Description

Technical Field

[0001] The utility model belongs to the technical field of battery processing, and in particular relates to a lithium battery positioning mechanism. Background Art

[0002] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. During the processing of lithium batteries, it is often necessary to position the lithium batteries, so processing positioning mechanisms are often used.

[0003] As for the product positioning mechanism of existing equipment and fixtures, in order to achieve simultaneous opening or retracting in four directions to complete positioning, most of them require multiple independent driving sources (such as cylinders or motors) and driving mechanisms to achieve this. In this way, the structure of the positioning mechanism will be relatively complex, occupy a large space, and also increase its production cost. Utility Model Content

[0004] In view of the above problems, the purpose of the present utility model is to provide a lithium battery positioning mechanism, aiming to solve the problems of the existing lithium battery positioning mechanism having a complex structure, occupying a large space and having a high manufacturing cost.

[0005] The utility model adopts the following technical scheme: the positioning mechanism includes a stand, a positioning plate is provided on the top of the stand, a pair of clamping cylinders are provided above the stand and at left and right positions, a pair of side plates are provided at front and rear positions, a pair of sliding bars are provided between the two side plates, slide plates are provided on the slide bars at the front and rear sides of the positioning plate, a driving block is provided on the driving shaft of each clamping cylinder, clamping blocks are provided on the slide plates and the driving blocks facing the positioning plate, a triangular linkage block is provided on the driving block, short blocks are provided on the left and right ends of each slide, a push rod is provided on the short block facing the linkage block on the same side, a roller is provided at the end of the push rod, and the roller is always in contact with the linkage block.

[0006] Furthermore, each slide bar is provided with a pair of limit blocks, and a matching spring is provided on the slide bar and between the limit blocks and the side plates.

[0008] Furthermore, each clamping block is bent upward to form a curled edge, and a mounting groove is formed on the curled edge. A locking nut is inserted into the mounting groove and a stopper is screwed into the groove.

[0009] Furthermore, a pair of avoidance openings are provided at the top and front and rear positions of the stand.

[0010] Furthermore, an adjustment slot is provided on the clamping block.

[0011] The beneficial effects of the utility model are as follows: first, the lithium battery is adsorbed by the suction cup, moved toward the positioning plate and the lithium battery is placed flat on the positioning plate as required, and then the four clamping blocks are simultaneously moved toward the four sides of the lithium battery until the lithium battery is clamped, and finally the lithium battery can be processed. After the processing is completed, the four clamping blocks are simultaneously moved outward and the battery is released, and the lithium battery is adsorbed by the mechanical arm again and unloaded.

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0017] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0018] Combination Figure 1-3 As shown, the positioning mechanism includes a stand 1, a positioning plate 2 is provided on the top of the stand 1, a pair of clamping cylinders 3 are provided above the stand 1 and at left and right positions, a pair of side plates 4 are provided at front and rear positions, a pair of slide bars 5 are provided between the two side plates 4, slide bars 6 are provided on the slide bars 5 at the front and rear sides of the positioning plate 2, a driving block 7 is provided on the driving shaft of each clamping cylinder 3, clamping blocks 8 are provided on the slide bars 6 and the driving blocks 7 facing the positioning plate 2, a triangular linkage block 9 is provided on the driving block 7, short blocks 10 are provided on the left and right ends of each slide bar 6, a push rod 11 is provided on the short block 10 facing the linkage block 9 on the same side, a roller 12 is provided at the end of the push rod 11, and the roller 12 is always in contact with the linkage block 9.

[0019] During the processing of lithium batteries, the positioning mechanism can be used to achieve the positioning of lithium batteries. Specifically, the lithium batteries are positioned by the mechanism, and at this time, the four clamping blocks located around the positioning plate are in the initial state.

[0020] First, you can use a robotic arm or other methods. The bottom of the robotic arm is a suction cup. The lithium battery is sucked by the suction cup, moved toward the positioning plate and the lithium battery is placed flat on the positioning plate as required. Then the four clamping blocks move toward the surroundings of the lithium battery at the same time until the lithium battery is clamped. Finally, the lithium battery can be processed. After the processing is completed, the four clamping blocks move outward at the same time and release the battery. The lithium battery is sucked by the robotic arm again and unloaded. The robotic arm is not the focus of this positioning mechanism, so it will not be described here.

[0021] As a preferred structure, combined with Figure 3 Each slide bar 5 is provided with a pair of limit blocks 13, and a matching spring 15 is provided on the slide bar 5 and between the limit blocks 13 and the side plate 4. When the front and rear clamping blocks are opened, all the springs are in a compressed state.

[0022] The clamping cylinder is used as a power source. When clamping and positioning the lithium battery, the two clamping cylinders first drive the driving blocks on the left and right sides to move inward at the same time. At this time, the left and right clamping blocks move toward the left and right sides of the lithium battery respectively until the left and right sides of the lithium battery are clamped. At the same time, the two linkage blocks move inward, and the spring gradually recovers its deformation, so that all the rollers move inward along the inclined surface of the linkage block. Under the action of the spring, the front and rear sides of the lithium battery are clamped by the corresponding two clamping blocks.

[0023] In the present structure, only a pair of clamping cylinders are used as the power source to achieve clamping and positioning of the battery in all directions, so that the positioning mechanism occupies less space, reduces its production cost, and makes the structure of the positioning mechanism simpler.

[0024] And as Figure 1 Each clamping block 8 is bent upward to form a curling edge, and a mounting groove 16 is opened on the curling edge. A locking nut is inserted into the mounting groove and a stopper 17 is screwed into the groove.

[0025] When the lithium battery is actually clamped and positioned, the block is mainly used to contact and position the corresponding side of the lithium battery. Each block can be adjusted to its installation position according to the specific specifications of the lithium battery, further improving the positioning effect of the lithium battery. When adjusting the installation position of the block, first loosen the locking nut, then the block can be adjusted along the length of the long slot, and after it is adjusted to the right position, tighten the locking nut.

[0026] As a further preferred structure, the push rod 11 is provided with a long slot 18, and an adjusting nut (not shown in the figure) is inserted into the long slot, and the adjusting nut is screwed into the short block 10 and locked. Since the short blocks are provided at both ends of the slide plate, the position of the slide plate can be fine-tuned by fine-tuning the installation position of the same pair of push rods, thereby adapting to lithium batteries of different lengths. When fine-tuning, loosen the adjusting nut and determine the installation position of the push rod, and then tighten the adjusting nut.

[0027] In addition, the clamping block 9 is provided with an adjustment slot 19. The front and rear clamping blocks 9 are both penetrated with fixing nuts, which are screwed into the slide plate 6 and locked. The left and right clamping blocks are penetrated with fixing nuts, which are screwed into the drive block and locked. By providing the adjustment slot on each clamping block, the installation position of the clamping block can be adjusted, and the mechanism can be further adapted to different lithium batteries, thereby improving the adaptability of the mechanism.

[0028] A pair of escape openings (blocked in the figure) are provided at the top and front and rear positions of the stand 1. A pair of escape openings are provided at the top of the stand, and the escape openings are used to escape the slide board on the same side.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
