As shown in fig. 1-7, the present invention provides an efficient sand blasting machine, which comprises a conveying mechanism 10, a sand blasting mechanism 20 and a housing 30.

The conveying mechanism 10 includes a collecting tank 11, a chain 12, a support bar 13, and a first motor 14. The top of collecting vat 11 is uncovered setting, and two parallel arrangement of chain 12 are at the top of collecting vat 11, and all pass through the bearing rotation with collecting vat 11 and be connected. Two install the bracing piece 13 that many intervals set up between chain 12, the both ends of every bracing piece 13 all with chain 12 fixed connection. The first motor 14 drives the two chains 12 to rotate synchronously by driving the rotating shaft. In use, a worker places a semiconductor substrate on the support bar 13, and the support bar 13 moves along with the chain 12 under the driving of the first motor 14, thereby driving the movement of the semiconductor substrate.

The sand blasting mechanism 20 includes a sand pump 21, a sand blasting pipe 22, a nozzle 23, and a shut-off structure 24. The inlet of the sand pump 21 is communicated with the bottom of the collecting tank 11, and the outlet is communicated with the sand blasting pipe 22. The plurality of nozzles 23 are arranged at the bottom of the sand blast pipe 22 at intervals and are communicated with the sand blast pipe 22. During the in-service use, take out the sand pump 21 and take out the sand water in the collecting vat 11, the semiconductor substrate that rethread shower nozzle 23 sprayed on conveying mechanism 10 carries out the sandblast operation, and after the sandblast operation was accomplished, the sand water can fall into to collect the groove 11 from the clearance between a plurality of bracing pieces 13 is automatic, realizes the cyclic utilization of sand water.

The plurality of intercepting structures 24 are all arranged in the sand blast pipe 22 and are respectively positioned between two adjacent spray heads 23. The shut-off structure 24 is used to prevent the sand water in the sand blast pipe 22 from flowing between two adjacent spray heads 23. When the size of the semiconductor substrate is small, the worker may select to open the corresponding shut-off structure 24 according to the actual size of the semiconductor substrate. The number of the blasting heads 23 for performing the blasting work is reduced and the flow rate of the blasting water sprayed from the other blasting heads 23 is increased, thereby further improving the efficiency of the blasting work. The intercepting structure 24 can be opened and closed according to the actual size of the semiconductor substrate, so that the number of the spray heads 23 for carrying out sand blasting operation is changed, and the semiconductor substrate can adapt to the semiconductor substrates with various sizes, and on one hand, the problem that the sand blasting efficiency is low due to the fact that the number of the spray heads 23 is too small when the semiconductor size is large is avoided; on the other hand, the sand water waste caused by the excessive number of the spray heads 23 when the semiconductor size is small can be avoided.

The shell 30 is sleeved outside the sand blasting mechanism 20, and openings for allowing the conveying mechanism 10 to pass through are formed in two ends of the shell 30, so that sand grains are prevented from splashing outwards, and the workshop environment is prevented from being polluted.

In one embodiment, in particular, the shut-off structure 24 includes a rotating member 241 and a shut-off plate 242. The lower end of the rotating member 241 is rotatably connected to the blast pipe 22, and the upper end thereof extends outward through the blast pipe 22. The rotating member 241 has a handle 243 at the top thereof, and the handle 243 can facilitate a worker to rotate the rotating member 241. The bottom of the rotating member 241 is provided with a threaded hole 244. The top of the closure plate 242 has a threaded portion 245 that mates with the threaded hole 244. When the shutoff plate 242 descends, the periphery of the shutoff plate 242 is attached to the inner wall of the sand blast pipe 22, so that the sand water in the sand blast pipe 22 is prevented from flowing; when the cut-off plate 242 is raised, the periphery of the cut-off plate 242 is separated from the inner wall of the sand blast pipe 22, and sand water in the sand blast pipe 22 can flow.

In one embodiment, the blast tube 22 has slots 221 therein that mate with the shut off plate 242. When the cut-off plate 242 is lowered, the cut-off plate 242 is inserted into the insertion slot 221. The arrangement of the slots 221 enables the cut-off plate 242 to be tightly attached to the inner wall of the sand blast pipe 22, so that the sealing performance can be further improved, sand water is effectively prevented from flowing out from a gap between the cut-off plate 242 and the inner wall of the sand blast pipe 22, and the cut-off effect is better.

In one embodiment, an agitation mechanism 40 is also included, disposed within collection tank 11. Since a part of sand in the sand water is deposited on the bottom of the collecting tank 11, the concentration of the sand water pumped by the sand pump 21 is greatly changed, and thus poor sand blasting of the surface of the semiconductor substrate is caused. Preferably, the stirring mechanism 40 includes a stirring shaft 41, a paddle 42, and a second motor 43. The stirring shaft 41 is arranged in the collecting tank 11, two ends of the stirring shaft are rotatably connected with the collecting tank 11 and kept sealed, the blades 42 are arranged on the stirring shaft 41, and the second motor 43 is used for driving the stirring shaft 41 to rotate. The stirring mechanism 40 stirs the sand water in the collecting tank 11, so that the concentration of the sand water is uniform, and the sand blasting yield of the semiconductor substrate is improved.

In one embodiment, the middle portion of the support rod 13 is sleeved with a flexible sleeve 131, and the flexible sleeve 131 is preferably made of silicone. The flexible sleeve 131 can prevent the semiconductor substrate from rigidly contacting the supporting rod 13, and prevent the supporting rod 13 from damaging the semiconductor substrate. The two ends of the support rod 13 are provided with threaded sections 132, and locking nuts 133 are respectively sleeved on the threaded sections 132. The worker can rotate the lock nuts 133 at both ends of the support rod 13 according to the size of the semiconductor substrate, so that the lock nuts 133 clamp the semiconductor substrate, thereby preventing the semiconductor substrate from being displaced under the impact of the blasting operation. The mounting of the lock nut 133 improves the stability of the blasting work.

In one embodiment, a brush 50 is mounted at each opening of the housing 30. The brushes 50 at the two ends can preliminarily clean the surface of the semiconductor substrate before sand blasting operation, and simultaneously clean part of sand grains remained on the semiconductor substrate after sand blasting operation, thereby avoiding manual cleaning of workers and reducing the labor intensity of the workers.
