Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stacking machines, and particularly relates to a stacking mechanism and a stacking machine. Background Technology
[0002] During the stacking of cores, partitions are placed on the stacking platform, and then the electrode stacking process is performed on the partitions. In one existing stacking machine, the width of the gripper is 6mm, the width of the gripper clearance groove on the stacking platform is 7.5mm, and the width of the suction plate is only 3mm. One gripper can extend into the clearance groove of the stacking platform and cooperate with the other gripper, so that the two grippers clamp and transfer the cores from the top and bottom.
[0003] Reference Figure 4 In existing stacking machines, during the stacking process, the partition 4 is located above the clearance groove 11, and the periphery of the partition 4 overlaps with other areas of the stacking platform. The suction plate 5 moves to be located above the clearance groove 11 and presses the partition 4 and electrode 6 on the stacking platform from top to bottom. Because the width of the suction plate 5 is smaller than the width of the clearance groove, the orthographic projection of the suction plate 5 on the stacking platform is located in the middle of the clearance groove 11. The suction plate 5 applies downward pressure to the electrode 6 and the partition 4 below the electrode 6. However, the area of the partition 4 directly facing the clearance groove 11 lacks support. Under the pressure of the suction plate 5, the partition 4 is prone to deformation, which ultimately leads to the deformation of the electrode 6. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a stacking mechanism and a stacking machine, which addresses the problem that existing stacking machines are prone to electrode deformation during the stacking process.
[0005] To solve the above problems, on the one hand, this utility model provides a stacking mechanism, including a clamp and a stacking platform. The stacking platform is provided with a clearance groove, which extends along a first direction. The clearance groove has an open end and a closed end opposite to each other in the first direction. From the open end to the closed end, the clearance groove includes a plurality of sub-grooves that are connected in sequence and whose cross-sectional areas decrease in sequence.
[0006] The clamp includes a base and a jaw, the jaw is connected to the base, the shape of the jaw is adapted to the shape of the clearance groove, and the jaw engages with the clearance groove when it extends into the clearance groove.
[0007] Optionally, the sub-slot extends through the stack along a second direction, wherein the first direction is perpendicular to the second direction.
[0008] Optionally, the gripper includes a plurality of sub-plates connected sequentially along the first direction, each sub-plate corresponding to one of the sub-slots, such that each sub-plate can be inserted into its corresponding sub-slot;
[0009] The length of the sub-plate along the first direction is the same as the length of its corresponding sub-slot along the first direction, and the length of the sub-plate along a third direction is less than the length of its corresponding sub-slot along the third direction, so that the gripper and the clearance groove are in clearance fit; the first direction and the third direction are perpendicular to each other.
[0010] Optionally, the sub-plate and its corresponding sub-slot are clearance-fitted, and the clearance between the sub-plate and its corresponding sub-slot is 0.4mm-0.6mm.
[0011] Optionally, the sub-plate is flat, the same side surface of the plurality of sub-plates is coplanar, and the thickness of the plurality of sub-plates decreases sequentially in the direction away from the base.
[0012] Optionally, a notch is provided at one end of the sub-plate that is furthest from the base, and a rubber plug connected to the sub-plate is provided in the notch.
[0013] Optionally, the length of the sub-slot gradually decreases towards the center of the stack along the first direction.
[0014] Optionally, three sub-slots are provided; along the first direction, the sub-slot farthest from the center of the stack has a length of 2mm-4mm, the sub-slot next closest to the center of the stack has a length of 5mm-7mm, and the sub-slot closest to the center of the stack has a length of 9mm-11mm.

[0017] The present invention provides a stacking mechanism and stacking machine in which the width of the clearance groove gradually decreases, thereby reducing the area of the partition that is suspended.

[0028] like Figures 1 to 3As shown, one embodiment of this utility model provides a stacking mechanism, referring to... Figure 1 and Figure 2 The system includes a clamp 2 and a stacking platform 1. The stacking platform 1 has a clearance groove 11 extending along a first direction. The clearance groove 11 has an open end and a closed end opposite to each other in the first direction. From the open end to the closed end, the clearance groove 11 includes a plurality of sub-grooves 111 connected sequentially and with progressively decreasing cross-sectional areas. The clamp 2 includes a base 21 and a gripper 22. The gripper 22 is connected to the base 21, and its shape is adapted to the shape of the clearance groove 11. When the gripper 22 extends into the clearance groove 11, it engages with the clearance groove 11 with a clearance fit. The gripper 22 extends into the clearance groove 11 along the first direction, thereby supporting the partition 4 and electrode 6 on the upper surface of the stacking platform 1, and clamping the stacked core with another gripper 22 above the stacking platform 1.
[0029] Reference Figure 1 and Figure 4 Compared to Figure 4 The prior art described in this embodiment is as follows: Figure 1 The width of the clearance groove 11 gradually decreases, reducing the area of the partition 4 that is suspended. When the partition 4 is placed on the stacking platform 1, the area of the partition 4 facing the clearance groove 11 decreases, which means that the area of the partition 4 overlapping other solid areas of the stacking platform 1 increases. The gradually narrowing clearance groove 11 provides support for the partition 4 on the stacking platform 1. Due to the change in the shape of the clearance groove 11, the gripper 22 is also improved in this embodiment. This allows the gripper 22 to enter the clearance groove 11 and fit with the clearance groove 11. If the existing long strip-shaped gripper 22 is still used, the width of the gripper 22 must be less than or equal to the width of the shortest sub-groove 111. At this time, the width of the gripper 22 is the narrowest, and the contact area with the partition 4 is the smallest, making it easy for the stacked core to slip off the gripper 22 during the transfer of the stacked core. While the width of the gripper 22, which is matched to the shape of the clearance groove 11, gradually decreases along the first direction, the width of a portion of the gripper 22 in this embodiment is still greater than that of the narrowest sub-groove 111, thereby improving the stability during the transfer of the core stack.
[0030] In one embodiment, the sub-groove 111 penetrates the stack 1 along a second direction, where the first direction is perpendicular to the second direction. The second direction is the thickness direction of the stack 1, and in actual production, the second direction is the vertical direction. In this embodiment, the clearance groove 11 penetrates the stack 1, allowing the gripper 22 to move vertically within the clearance groove 11 after entering it, thus providing more vertical movement space for the gripper 22 within the clearance groove 11.
[0031] In one embodiment, the gripper 22 includes a plurality of sub-plates 221 connected sequentially along the first direction. Each sub-plate 221 corresponds to one of the sub-slots 111, such that each sub-plate 221 can be inserted into its corresponding sub-slot 111. The length of the sub-plate 221 along the first direction is the same as the length of its corresponding sub-slot 111 along the first direction. The width of the sub-plate 221 along a third direction is less than the width of its corresponding sub-slot 111 along the third direction, such that the gripper 22 and the clearance groove 11 are in clearance fit. The first direction and the third direction are perpendicular to each other. The third direction is the width direction of the gripper 22, and also the width direction of the base 21 and the sub-plate 221.
[0032] In this embodiment, the width of multiple sub-plates 221 decreases along the direction away from the base 21, but the width of each sub-plate 221 is constant. The width of two adjacent sub-plates 221 decreases along the first direction, so that the sub-plates 221 decrease in a step-like manner, and their decreasing trend is the same as that of the sub-groove 111.
[0033] Reference Figure 3 In one embodiment, the sub-plate 221 and its corresponding sub-slot 111 are clearance-fitted, and the clearance between the sub-plate 221 and its corresponding sub-slot 111 is 0.4mm-0.6mm. In this embodiment, the sub-plate 221 is clearance-fitted with the sub-slot 111 along its width direction, and the clearance between the width side of the sub-plate 221 and the width side of the sub-slot 111 is generally controlled at 0.5mm. If the clearance is too large, the width of the sub-plate 221 is reduced, and the stacked cores are prone to falling off during the transfer process. If the clearance is too small, the processing difficulty of the sub-plate 221 and the sub-slot 111 increases, and the cost increases.
[0034] In one embodiment, the sub-plate 221 is flat, with the same side surface of multiple sub-plates 221 being coplanar, and the thickness of the multiple sub-plates 221 decreasing sequentially in the direction away from the base 21. In this embodiment, the thickness of the multiple sub-plates 221 is not uniform, and the thickness decreases sequentially in the direction away from the base 21, that is, the thickness of the multiple sub-plates 221 decreases in a stepped manner in the direction away from the base 21. This allows the sub-plates 221 to have greater vertical movement space in the clearance groove 11, and also reduces the material usage of the sub-plates 221 to a certain extent.
[0035] In one embodiment, a notch is provided at one end of the sub-plate 221, which is furthest from the base 21, and a rubber plug 3 connected to the sub-plate 221 is provided in the notch 23. In this embodiment, the notch 23 and the rubber plug 3 are provided on the side of the sub-plate 221 that is in contact with the partition 4 and the stacked core. The rubber plug 3 is used to increase the friction to ensure that the gripper 22 stably clamps the partition 4 and the stacked core.
[0036] In one embodiment, the length of the sub-slot 111 gradually decreases towards the center of the stack 1 along the first direction. In this embodiment, the length of the wider sub-plate 221 is greater than the length of the narrower sub-plate 221. The rigidity of the sub-plate 221 decreases as the width decreases. However, since the thickness and width of the sub-plate 221 near the base 21 are relatively large, its rigidity is higher than that of the other sub-plates 221. Compared with the thinner gripper 22 with a uniform width, the sub-plate 221 in this embodiment is less likely to bend.
[0037] In one embodiment, three sub-slots 111 are provided; the length of the sub-slot 111 furthest from the center of the stack 1 along the first direction is 2mm-4mm. For ease of understanding, in actual production, the length of the sub-slot along the first direction is generally referred to as the slot width. When the length of the innermost sub-slot along the first direction is less than 2mm, that is, the slot width of the sub-slot is too small, which makes processing difficult and costly. When the length of the innermost sub-slot along the first direction is greater than 4mm, the slot width of the sub-slot is too large, resulting in insufficient support. The length of the sub-slot 111 closest to the center of the stack 1 is 5mm-7mm. When the length of the innermost sub-slot along the first direction is less than 5mm, processing is difficult and costly. When the length of the innermost slot along the first direction is greater than 7mm, the slot width of the sub-slot is too large, resulting in insufficient support. The length of the sub-slot 111 closest to the center of the stack 1 along the first direction is 9mm-11mm. In this embodiment, when the length of the innermost sub-groove along the first direction is less than 9mm, the processing is difficult and costly. When the length of the innermost sub-groove along the first direction is greater than 11mm, the groove width of the sub-groove is too large, resulting in insufficient support.
[0038] In one embodiment, both sides of the open end are rounded. In this embodiment, the rounded corners facilitate the entry of the gripper 22 from the open end toward the closed end.
[0039] In addition, this utility model embodiment provides a stacking machine, including the stacking mechanism described above.
[0040] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
