[0002] Existing processing jigs are mainly used to place and clamp battery covers during the product production process; however, existing processing jigs usually have the following problems: First, the size of the loading slot on the jig is difficult to adapt to battery covers of different sizes, and multiple sets of jigs of different sizes can only be prepared for use, which has a correspondingly higher manufacturing cost, and replacing jigs to adapt to different sizes is also more time-consuming; second, after the battery cover is placed in the loading slot, the wall of the loading slot is prone to friction contact with the side of the battery cover, and the side is prone to scratching and bumping the product surface, affecting product quality; third, after the battery cover is clamped and during subsequent operations, the battery cover usually has thermal expansion, so the battery cover becomes larger and is easily stuck in the loading slot. Subsequent processing can only be completed after waiting for the battery cover to cool down before the battery cover can be taken out, resulting in low production efficiency; fourth, due to the thermal expansion of the battery cover, it is easy to be squeezed and deformed in the loading slot, which damages product quality.

[0003] In summary, the existing processing fixtures still need to be further improved to meet actual usage needs. Utility Model Content

[0015] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The utility model provides a new type of processing jig for battery cover plates, which can solve the problem that the battery cover plates are easily stuck and the product quality is easily damaged when the existing processing jigs are clamped. The technical solution of the present invention is that the loading slot in the fixture body is provided with a clamping mechanism and an ejection mechanism at the same time; wherein the clamping mechanism includes at least two elastic holding components, and the two elastic holding components act on the two opposite ends of the battery cover through elastic holding force, so that battery covers of different sizes can be effectively adapted, and there is no need to worry about unstable clamping, inability to clamp, or easy squeezing and deformation of the battery cover when it expands due to thermal expansion. During the operation, there is no need to wait for the battery cover to cool down and it can be quickly taken out, so the production efficiency is high; and after the clamping and subsequent operations are completed, the battery cover is pushed upward by the ejection mechanism for a certain distance, so that the battery cover is partially separated from the clamping of the clamping mechanism, so that when the battery cover is taken out of the loading slot, the size of the friction surface between the battery cover and the holding component can be reduced, so that it is easier to take out later and the outer surface of the battery cover is protected. This not only protects the product quality and reduces the scrap rate, but also the processing fixture can adapt to battery covers of different sizes and has high production efficiency.

[0017] (2) In this technical solution, the push wheel abandons the columnar structure and adopts a cam-shaped structure, which has a more stable ejection effect. Even if it is used for a long time, there is no need to worry about its breakage or deformation. The service life is longer, ensuring production efficiency.

[0018] (3) In this technical solution, a guide tooth is formed around the outer periphery of the disc portion, so that the guide member only needs to push the guide tooth, and the disc portion will directly rotate. The mechanical structure is more simplified, the assembly is also easy, and the transmission stability is guaranteed.

[0019] (4) In the present technical solution, radial extensions are respectively formed on both sides of the disc portion to form a rotating shaft structure, and the rotating shaft is blocked in the rotating cavity at the lower end of the fixture body by the support plate; when the disc portion is rotating, the linked rotating shaft is also limited to rotate in the rotating cavity, so that the disc portion is not easy to tilt or swing during rotation, and the transmission efficiency is guaranteed.

[0020] (5) In this technical solution, a torsion spring is sleeved on the rotating shaft so that the push wheel can automatically rotate and reset toward the inside of the through hole after passing through the through hole. The mechanical structure is simple and the cost is low.

[0021] (6) In this technical solution, the fixture body is provided with a receiving cavity, and each elastic supporting component is located in each receiving cavity, so that the size of the loading slot can be accommodated without occupying the internal loading slot space, thereby ensuring the volume of the loading slot to adapt to a larger size of battery cover and reduce operating costs.

[0022] (7) In this technical solution, the guide column on the rear side of the sliding block can ensure that when the sliding block applies an elastic holding force toward the battery cover, the battery cover is not easy to tilt or separate from the fixture body, thereby ensuring the stability of the clamping function.

[0039] See Figures 1 to 9 .

[0040] This embodiment provides a new type of processing jig for battery cover Y, which is used to load battery cover Y and can solve the problem that the battery cover Y is easily stuck and the product quality is easily damaged when the existing processing jig is clamped. The processing jig mainly includes a jig body 1, a clamping mechanism 2 and an ejection mechanism 3; wherein,

[0041] Jig body 1, see Figure 1It has at least one loading slot 11 for placing the battery cover Y, and the opening of the loading slot 11 is vertically upward; the loading slots 11 on the fixture body 1 can be provided with two or more, according to actual production needs; and setting the opening vertically upward makes it easier to accurately align the battery cover Y and place it in the loading slot 11, reducing deviation.

[0042] Clamping mechanism 2, see Figure 1 , which is used to limit and fix the battery cover Y in the loading slot 11, preventing the battery cover Y from leaving the loading slot 11 and from automatically deviating significantly in the loading slot 11. The clamping mechanism 2 includes at least two elastic supporting components 21 provided on the inner side wall of the loading slot 11. The two elastic supporting components 21 are horizontally arranged on the opposite wall surfaces of the loading slot 11. The two opposite elastic supporting components 21 apply corresponding elastic supporting forces, which will clamp and fix the battery cover Y located between the two elastic supporting components 21. Since the elastic supporting components 21 apply elastic supporting forces, the flexible force generated by them can automatically change and adjust to adapt to battery covers Y of different sizes, and is less likely to damage the side surface of the battery cover Y. In this embodiment, the elastic supporting components 21 are arranged in groups of two, with each two being arranged opposite to each other and corresponding to each other on the inner wall surface of the loading slot 11. The number of groups can be set according to needs.

[0043] The ejection mechanism 3 is located at the lower end of the loading slot 11; the ejection mechanism 3 includes a guide 31 and a pushing wheel 32. The guide 31 acts on the pushing wheel 32 to drive the pushing wheel 32 to rotate and guide it through the through hole 111 opened on the bottom wall of the loading slot 11 to apply a force to the battery cover Y, so that the battery cover Y is pushed upward by the pushing wheel 32 for a certain distance, so that the battery cover Y, in this embodiment, there are two ejection mechanisms 3, which are respectively provided at both ends of the loading slot 11. When pushing upward, the entire battery cover Y can be pushed upward, so that the side wall surface of the battery cover Y is partially separated from the clamping mechanism 2, reducing some friction, and facilitating the subsequent manipulator or suction cup to drive it out of the fixture.

[0044] It is worth noting that in this embodiment, the battery cover Y is only pushed upward a certain distance by the pushing wheel 32, and the battery cover Y is not completely released from the clamping of the clamping mechanism 2; if it is directly released from the clamping, the battery cover Y may be displaced left and right in the loading slot 11, and the subsequent robot arm or suction cup will not be able to pick it up accurately.

[0045] In this embodiment, see Figure 2The push wheel 32 is cam-shaped and includes a disc portion 321 and a protrusion 322 integrally formed in the through hole 111. A guide tooth 321A is formed around the outer periphery of the disc portion 321. A rotating shaft 323 is radially extended on both sides of the disc portion 321. A torsion spring 323A is sleeved on the rotating shaft 323, so that the push wheel 32 can always rotate toward the inside of the through hole 111 under the action of the torsion spring 323A. Figure 3 and Figure 4 The guide member 31 is a push cylinder (not shown in the figure). The output end of the push cylinder acts on the guide tooth 321A of the push wheel 32 to drive the disc portion 321 of the push wheel 32 to rotate until the protrusion 322 of the push wheel 32 passes through the through hole 111 opened on the bottom wall of the loading slot 11, until it acts on the lower end of the battery cover Y to push the battery cover Y upward for a certain distance.

[0046] In this embodiment, see Figure 8 and Figure 9 The ejection mechanism 3 also includes two support plates 33 respectively provided at the lower ends of the two rotating shafts 323. The support plates 33 block and limit the rotating shaft 323 and install it in the rotating cavity 12 opened at the lower end of the fixture body 1, so that when the disc part 321 rotates, the linkage rotating shaft 323 is also limited to rotate in the rotating cavity 12, so that the disc part 321 is not easy to tilt or swing during the rotation process.

[0047] In this embodiment, see Figure 3 and Figure 5 The fixture body 1 is formed with a plurality of accommodating cavities 13 connected to the loading slots 11, and each elastic supporting component 21 is respectively located in the accommodating cavity 13 to apply a supporting force to the battery cover Y. Figure 6 and Figure 7 The elastic supporting assembly 21 includes a sliding block 211 and a guide spring 212 and a guide column 213 arranged on the rear side of the sliding block 211. The sliding block 211 applies an elastic supporting force toward the battery cover Y under the action of the guide spring 212, and the guide column 213 is inserted into the guide hole 14 formed in the fixture body 1, and the guide hole 14 is connected to the accommodating cavity 13.

[0048] In this embodiment, an elastic layer is formed on the sliding block 211, and the elastic layer is a plastic layer, elastic fabric, etc. The sliding block 211 is in contact with the battery cover Y through the elastic layer, thereby playing a protective role.

[0049] In this embodiment, the fixture body 1 is mainly made of plastic steel and bakelite. Even if the battery cover Y expands due to heat, the temperature is transferred to the fixture body 1 and it is not easy to generate high temperature.

[0050] The working principle and use process of this utility model:

[0051] When using the fixture,

[0052] First, the battery cover Y can be placed manually, by a robot, or by using a suction cup into one of the loading slots 11 of the fixture body 1. Each corresponding set of sliding blocks 211 in the loading slot 11 will be compressed and moved backward by the rear guide spring 212. The generated reaction force will act on the side wall of the battery cover Y, thus clamping the battery cover Y.

[0053] Next, the external machine is controlled to process the battery cover Y. At this time, the battery cover Y will begin to heat up and expand and deform, and each group of sliding blocks 211 will move back slightly to make way.

[0054] Afterwards, see Figure 1 and Figure 2 At this time, the push wheel 32 is in the initial state and has not started working; Figure 3 and Figure 4 The output end of the external push cylinder (not shown) is controlled to act on the guide tooth 321A of the disc portion 321, controlling the rotation of the disc portion 321, causing the protrusion 322 to pass through the through hole 111 in the bottom wall of the loading slot 11 until it acts on the lower end of the battery cover Y, pushing the battery cover Y upward a certain distance, causing the side wall of the battery cover Y to partially break away from the clamping mechanism 2, completing partial loosening and reducing some friction; finally, the battery cover Y can be controlled to be removed by the manipulator and suction cup. This utility model can solve the problem that the battery cover Y is easily stuck when clamping the battery cover Y with existing processing jigs, which easily damages the product quality. According to the technical solution of the present invention, the loading slot 11 in the fixture body 1 is provided with a clamping mechanism 2 and an ejection mechanism 3 at the same time; wherein the clamping mechanism 2 includes at least two elastic holding components 21, and the two elastic holding components 21 act on the two opposite ends of the battery cover Y through elastic holding force, so that battery covers Y of different sizes can be effectively adapted, and there is no need to worry about unstable clamping, inability to clamp, or easy squeezing and deformation of the battery cover Y when it expands due to thermal expansion. During the operation, there is no need to wait for the battery cover Y to cool down and it can be quickly taken out, which has high production efficiency; and after clamping and subsequent operations are completed, the battery cover Y is pushed upward by the ejection mechanism 3 for a certain distance, so that the battery cover Y is partially separated from the clamping of the clamping mechanism 2, so that when the battery cover Y is taken out of the loading slot 11, the friction surface size of the battery cover Y and the holding component can be reduced, and it is easier to take out and the outer surface of the battery cover Y is protected. This not only protects the product quality and reduces the scrap rate, but also the processing fixture can adapt to battery covers Y of different sizes, and has high production efficiency.

[0055] The above description and embodiments are used to explain the scope of protection of the utility model, but do not constitute a limitation on the scope of protection of the utility model. Based on the enlightenment of the utility model or the above embodiments, modifications, equivalent replacements, or other improvements to the embodiments of the utility model or part of the technical features thereof that can be obtained by ordinary technicians in this field through logical analysis, reasoning, or limited experiments in combination with common knowledge, ordinary technical knowledge in this field and / or existing technology should be included in the scope of protection of the utility model.
