Description

TECHNICAL FIELD

[0001] The present application relates to the field of lithium battery manufacturing, and particularly relates to a battery cell transfer clamp. BACKGROUND

[0002] The battery cell is the smallest unit of the power battery and an electric energy storage unit. The battery cell must have a high energy density to store as much electric energy as possible, so that the electric vehicle has a longer cruising range. In addition, the service life of the battery cell is also a key factor. Damage to any battery cell will result in damage to the entire battery pack.

[0003] In the process of battery cell production, a plurality of battery cells are placed together and separated by a partition plate. In the prior art, a battery cell transfer clamp is disclosed in Chinese Patent No. CN 219468960 U. The battery cell transfer clamp is provided with an adjusting mechanism between the battery cell pressing plate and the clamping plate and two clamping assemblies, so that the battery cell pressing plate and the clamping plate can be adjusted, thereby making the clamp suitable for battery cells of different sizes. After clamping the battery cell, the deformation of the spring remains unchanged, thereby ensuring that the clamping force is consistent when clamping battery cells of different sizes, and avoiding the situation that the clamping force is too large to damage the battery cell. When the device is used, although different track battery cells can be fixed, the device needs to be adjusted relatively complexly to realize the fixation of the battery cell, and the fixation efficiency is relatively low. SUMMARY

[0004] The purpose of the present application is to provide a battery cell transfer clamp, To achieve the above purpose, the present application provides the following technical scheme: A battery cell transfer clamp, comprising parallel base plates and cover plates, the base plates and the cover plates have a partition area therebetween, the partition area comprises a plurality of partition plates arranged in rows and spaced apart, and the partition plates and the base plates are movably connected together by a positioning mechanism.

[0005] Further scheme: the positioning mechanism comprises a clamping frame, the clamping frame has an upper boss and a lower boss; a side groove is formed in the edge of the base plate, and the side groove has an outer contour that simultaneously accommodates the upper boss and the lower boss.

[0006] Further scheme: the positioning mechanism further comprises a positioning screw; the clamping frame further comprises a slot opening between the upper boss and the lower boss; the positioning screw penetrates the slot opening and abuts against the side groove.

[0007] Further scheme: a guide groove for accommodating the extended end of the positioning screw is further formed in the base plate at the bottom of the side groove, and the guide groove is parallel to the side groove.

[0008] Further scheme: further include the bottom plate arranged at the bottom of the substrate; the length of the bottom plate is longer than the substrate; the positioning rod is arranged at the edge of the bottom plate, and the positioning rod penetrates the substrate and the cover plate in sequence.

[0009] Further scheme: the limiting ring is sleeved on the positioning rod.

[0010] Further scheme: the upper boss and the lower boss are provided with a gap at the lower edge of the partition plate.

[0012] Further scheme: the clamping frame further includes the edge part connecting the upper boss and the lower boss; the top of the edge part extends upward to form a convex rod part, and the convex rod part is fixedly connected with the side edge of the partition plate.

[0013] Compared with the prior art, the beneficial effects of the present application are: The present application realizes stepless adjustment of the distance between the partition plates through the sliding adjustment of the clamping frame in the side groove and the locking of the positioning screw, and adapts to the rapid switching of the production line of different sizes of battery cells. Compared with the traditional clamp, the adjustment time is greatly shortened.

[0014] The upper boss and the lower boss of the clamping frame in the present application are designed in pairs to solve the problem that the traditional single-point buckle is easy to cause the clamping frame to tilt and fall out of the groove due to vibration.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are directions or positional relationships in which the inventive product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0019] See also Figures 1-5 In this embodiment, a transfer fixture includes a base plate 1 and a cover plate 2, which are parallel to each other. A partition area 3 is defined between the base plate 1 and the cover plate 2. The partition area 3 includes a plurality of partitions 4 arranged in rows and spaced apart. The partitions 4 are movably connected to the base plate 1 via a positioning mechanism 5. The positioning mechanism 5 can adjust the distance between the partitions 4 and fix them.

[0020] Furthermore, the positioning mechanism 5 includes a bracket 51 having an upper boss 511 and a lower boss 512. A side groove 11 is provided on the edge of the base plate 1. The side groove 11 has an outer contour that can accommodate both the upper boss 511 and the lower boss 512. The bracket 51 can slide back and forth along the side groove 11 within a limited range. The bracket 51 is fixed to the lower left and right corners of the partition 4. The bracket 51 can be easily added or removed from both ends of the side groove 11. The upper boss 511 and the lower boss 512 are arranged parallel to each other in the vertical direction. The two are connected by an edge 513 to form an "I"-shaped cross-section. The upper boss 511 and the lower boss 512 are simultaneously embedded in the side groove 11, forming a two-way constraint to limit the upward and downward movement of the bracket 51.

[0021] Further, the positioning mechanism 5 further comprises a positioning screw 52; the clamping frame 51 further comprises a notch 514 which is opened between the upper boss 511 and the lower boss 512; the positioning screw 52 penetrates through the notch 514 and abuts against the side groove 11. The positioning screw 52 is threadedly connected with the clamping frame 51. The notch 514 is located between the double bosses and is used for penetrating the positioning screw 52, and the width thereof is slightly larger than the diameter of the positioning screw 52, thereby providing a fine adjustment allowance. The pre-tightening positioning screw 52 can make the extending end thereof abut against both sides of the base plate 1 (the side groove 11), so as to fix the position of the partition plate 4.

[0022] Further, the base plate 1 at the bottom of the side groove 11 is further provided with a guide groove 12 which is used for accommodating the extending end of the positioning screw 52 and is parallel to the side groove 11. The cross section of the guide groove 12 is U-shaped or rectangular, and when the clamping frame 51 slides in the side groove 11, the extending end of the positioning screw 52 synchronously slides in the guide groove 12. The interaction between the guide groove 12 and the positioning screw 52 forces the partition plate 4 to keep a vertical state, and when the positioning screw 52 is locked, the extending end of the positioning screw 52 is pressed against the side wall of the guide groove 12, thereby forming a rigid constraint. In addition, the guide groove 12 serves as a sacrificial groove, and the wear only occurs at the end of the replaceable positioning screw 52 and in the guide groove 12 (the groove can be plated with hard chromium, thereby facilitating repair and replacement), thereby avoiding the direct friction between the positioning screw 52 and the base plate 1, so as to prevent the base plate from being scratched.

[0023] Further, the bottom plate 6 which is provided at the bottom of the base plate 1 is further provided; the length of the bottom plate 6 is longer than that of the base plate 1; the positioning rod 7 is mounted at the edge of the bottom plate 6; the first positioning hole 13 which corresponds to the positioning rod 7 is opened at the periphery of the base plate 1; the second positioning hole 21 which corresponds to the positioning rod 7 is opened at the periphery of the cover plate 2; and the positioning rod 7 penetrates through the base plate 1 and the cover plate 2 in sequence, so that the bottom plate 6, the base plate 1 and the cover plate 2 form a “sandwich” structure skeleton, thereby increasing the overall stability of the clamp and improving the reliability during transportation.

[0024] Further, the positioning rod 7 is sleeved with the limiting ring 8, the limiting ring 8 is used for supporting and limiting the cover plate 2, thereby preventing the cover plate 2 from extruding the battery cell or the partition plate 4. The position of the limiting ring 8 can be fixed through screwing or buckling, and the height thereof can be adjusted, so as to adapt to the transfer of battery cells with different sizes.

[0025] Further, the upper boss 511 and the lower edge of the partition plate 4 form a narrow slit, and the height of the narrow slit is slightly higher than the thickness of the side groove 11, so that the partition plate 4 does not interfere with the base plate 1 during installation.

[0026] Further, the handle 9 which is provided at both ends of the base plate 1 is further provided.

[0027] Further, the clamping frame 51 further comprises the edge portion 513 which connects the upper boss 511 and the lower boss 512; the top of the edge portion 513 extends upwards to form the convex rod portion 5131, and the convex rod portion 5131 is fixedly connected with the side edge of the partition plate 4.

[0028] In the installation, first, according to the size and quantity of the battery to be transported, the number of partitions 4 is determined, the partitions 4 are pushed from the end of the side groove 11, the partitions 4 are adjusted, then the battery is placed between the adjacent partitions 4, then the positioning bolt 52 is pre-tightened, the connection between the partition 4 and the base plate 1 is fixed, finally, the cover plate 2 is covered, the positioning rod 7 penetrates the first positioning hole 13 and the second positioning hole, and then the transportation is carried out.

[0029] Although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.

[0030] Therefore, the above description is only a preferred embodiment of the present application, and is not intended to limit the scope of the present application; that is, any equivalent transformation within the scope of the claims of the present application is within the protection scope of the claims of the present application.
