Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes.
The embodiment 1 of battery core surface roll pressure trimmer of the present invention, as Figure 1-Figure 2, including rack 1 and is arranged on rack
The conveyer belt 2 for being used to convey battery core 11 on 1.Conveyer belt 2 is smooth surface conveyer belt, will not generate coining, and have to battery core surface
Adhesive force.Convey bandwidth 450mm.Conveyer belt is driven by motor, and conveying speed 0.3m/s, rotating speed is adjustable.Rack is equipped with four
A rubber roller, respectively the first rubber roller 8, the second rubber roller 9, third rubber roller 3, the 4th rubber roller 7.Each rubber roller along battery core conveying direction according to
Secondary arrangement, top roller diameter 75mm, length 450mm.In the present embodiment, the first rubber roller 8, the second rubber roller 9, third rubber roller the 3, the 4th
7 left and right directions arranged for interval of rubber roller.The vertical distance between conveyer belt of each rubber roller is gradually reduced to realize rubber roller to battery core
Multistage roll-in, specifically, the first rubber roller 8, the second rubber roller 9, third rubber roller 3, the 4th rubber roller 7 minimum point and conveyer belt 2 on
The vertical distance on surface is denoted as H1, H2, H3, H4, and H1 ＞ H2 ＞ H3 ＞ H4 respectively.Vertical distance namely gap, the model in gap
It is trapped among 0~20mm.
Supporting plate 10 is equipped in the position of rubber roller in rack, supporting plate 10 lifts conveyer belt 2, and the upper side of supporting plate is flat
Face.Supporting plate uses steel plate, by setting supporting plate, coordinates in roll-in position and rubber roller, and roll-in can be prevented uneven.
Each rubber roller is supported by cylinder 5, and cylinder 5 is fixed in rack 1.Cylinder 5 is double-rod cylinder, and cylinder upper end is equipped with bearing
Seat 4, rubber roller is assemblied in by bearing on bearing block.Cylinder uses in pairs namely a rubber roller is to a pair of of cylinder, this is to cylinder
It is distributed rack both sides.Rack is equipped with hand control valve 6, and hand control valve 6 is connected with cylinder 5 by corresponding tracheae.
It advanced optimizes, is additionally provided with grating in charging delivery end in rack, is used cooperatively with relay.When having detected electricity
During core, whole equipment is primary with regard to automatic running.
It advanced optimizes, hairbrush is additionally provided in rack, conveyer belt is cleared up.
The embodiment of battery core surface of the present invention shaping methods, includes the following steps, 1), battery core lain in a horizontal plane in into conveyer belt
On, 2), under the conveying of conveyer belt, battery core successively by more than two rubber rollers, between each rubber roller and conveyer belt it is vertical away from
From being gradually reduced, to realize multiple roll-in of the rubber roller to battery core.
