Description

Technical Field

[0001] This utility model relates to the technical field of battery terminal processing equipment, and in particular to a conveying type battery terminal fixing ring bending mechanism. Background Technology

[0002] In new energy batteries, the battery top cover is mainly composed of three parts: the main cover plate, the explosion-proof valve, and the positive and negative terminals. One type of positive and negative terminal is injection molded by combining the electrode block and the fixing ring. Therefore, the fixing ring needs to be bent to cover the electrode block in order to increase the thrust and pull of the terminal.

[0003] Existing methods for bending fixed rings mostly use molds in conjunction with riveting machines to extrude and bend the rings. However, the molds are expensive to manufacture and also have problems such as long manufacturing and debugging cycles.

[0004] Patent CN202420709701 also proposes a fixed ring bending mechanism, which uses a clamping head and a fixed ring support to vertically clamp the fixed ring, then uses a support head to tighten the fixed ring at the four corner notches, and finally uses a bending head to move inwards to simultaneously bend the four side walls of the fixed ring. Due to the concentrated location of the various components, there is a problem with material feeding. Utility Model Content

[0006] This application provides a conveying type battery terminal fixing ring bending mechanism, including a base plate and a pressing mechanism and a bending mechanism disposed on the top of the base plate. The base plate is provided with a horizontally oriented and rotatable conveyor belt suspended above it. The outer surface of the conveyor belt is provided with a tooling seat. The tooling seat has a fixing ring placement groove at the top center position. The side wall of the fixing ring placement groove is provided with a bending avoidance groove.

[0007] The clamping mechanism includes a mounting bracket and a clamping head. The mounting bracket is equipped with a positioning sensor for monitoring the positioning of the fixing ring. The clamping head is positioned above the conveyor belt and is mounted on the mounting bracket in a manner that allows it to move up and down in a directional manner.

[0008] The bending mechanism is symmetrically distributed on both sides of the conveyor belt, including a bending head that can be horizontally oriented to approach or move away from the conveyor belt. The bending head is directly below the pressing head, so that when the pressing head presses the fixed ring in the fixed ring placement groove, the bending head can bend the fixed ring in the corresponding bending clearance groove.

[0009] In one possible implementation, the mounting bracket includes uprights symmetrically distributed on both sides of the conveyor belt and a mounting plate connected to the top of the two uprights. The clamping mechanism further includes a clamping cylinder mounted on the mounting plate. The clamping cylinder has a bottom telescopic shaft, and the clamping head is fixedly mounted on the bottom telescopic shaft. The positioning sensor is mounted on the mounting plate.

[0010] In one possible implementation, the bottom end of the bottom telescopic shaft is vertically connected to an adapter plate, the clamping head is installed on the bottom of the adapter plate, and the bottom of the adapter plate is also symmetrically equipped with positioning pins on the outside of the clamping head. The positioning pins protrude from the clamping head below, and the top of the tooling base is provided with positioning holes that cooperate with the positioning pins.

[0011] In one possible implementation, the mounting plate has mounting holes at both ends that mate with the column and linear holes distributed on both sides of the mounting holes, wherein the linear holes near the ends are open holes, and locking screws perpendicularly penetrating the open holes are installed at both ends of the mounting plate.

[0012] In one possible implementation, a rotary motor and two fixed plates are mounted on the top of the base plate. The two fixed plates are symmetrically distributed on both sides of the conveyor belt and connected to a conveyor belt support. The bending mechanism is mounted on the top of the fixed plates. A drive wheel and a driven wheel are respectively mounted on opposite ends of the conveyor belt support. The conveyor belt is wound between the drive wheel and the driven wheel. A rotary wheel is fixedly sleeved on the rotating shaft of the rotary motor. The rotary wheel is connected to the drive wheel via a transmission belt.

[0013] In one possible implementation, the bending clearance grooves are distributed in a cross shape on the sidewall of the fixed ring placement groove, and the bending mechanism has four of them.

[0014] In one possible implementation, the bending mechanism includes an L-shaped mounting plate and a bending cylinder. The L-shaped mounting plate includes a vertical plate at one end away from the conveyor belt. The bending cylinder is mounted on the outer side of the vertical plate, and the output shaft of the bending cylinder passes vertically through the vertical plate. The bending head is mounted at the end of the output shaft of the bending cylinder.

[0015] In one possible implementation, the L-shaped mounting plate further includes a horizontal plate near one end of the conveyor belt, the top of the horizontal plate is provided with a guide rail, the guide rail extends along the extension and retraction direction of the output shaft of the bending cylinder, and a slider that slides with the guide rail is connected between the bending head and the output shaft of the bending cylinder.

[0016] In one possible implementation, the top of the cross plate is symmetrically provided with limit plates on both sides of the bending head, the slider is connected with adjusting screws, the adjusting screws extend along the extension and retraction direction of the output shaft of the bending cylinder and are respectively facing the limit plates.

[0017] In one possible implementation, a protective cover is mounted on the top of the base plate, the protective cover extends along the conveying direction of the conveyor belt, both ends of the conveyor belt protrude from the protective cover, and the pressing mechanism and the bending mechanism are both located inside the protective cover.

[0018] Beneficial effects: Compared with the prior art, the conveyor-type battery terminal fixing ring bending mechanism provided in this application uses the continuous directional rotation of the conveyor belt to drive the tooling seat to circulate through the clamping mechanism and the bending mechanism. After reaching the appropriate position, the clamping mechanism clamps the fixing ring in the fixing ring placement groove. Then, the bending head bends the fixing ring in the bending clearance groove, which makes it easier to unload the material during the bending operation, making the unloading more convenient and effectively improving the work efficiency.

[0019] The use of locating pins and locating holes allows for more precise clamping and fixing of the retaining ring, preventing product misalignment during bending and ensuring bending quality.

The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0028] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0029] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0030] refer to Figures 1 to 6 This application provides a conveying type battery terminal fixing ring bending mechanism, including a base plate 10 and a pressing mechanism 20 and a bending mechanism 30 disposed on the top of the base plate 10. The base plate 10 is provided with a horizontally oriented rotating conveyor belt 11 suspended above it. The outer surface of the conveyor belt 11 is provided with a tooling seat 12. The tooling seat 12 is provided with a fixing ring placement groove 101 at the top center for placing a fixing ring. The side wall of the fixing ring placement groove 101 is provided with a bending avoidance groove 102 (or avoidance channel), and the bending avoidance groove 102 is symmetrically distributed with respect to the conveying direction of the conveyor belt 11.

[0031] The clamping mechanism 20 includes a mounting bracket 21 and a clamping head 22. The mounting bracket 21 is equipped with a positioning sensor 23 for monitoring the positioning of the fixing ring. After the positioning ring is detected to be in position, the sensor sends a signal to the controller, which then controls the conveyor belt 11 to stop operating. The clamping head 22 is positioned above the conveyor belt 11 and is mounted on the mounting bracket 21 in a way that allows it to move up and down in a directional manner. It is used to clamp the fixing ring after it is in position.

[0032] The bending mechanism 30 is symmetrically distributed on both sides of the conveyor belt 11, including a bending head 31 that can be horizontally oriented to approach or move away from the conveyor belt 11. The bending head 31 is directly below the pressing head 22, so that when the pressing head 22 presses the fixed ring in the fixed ring placement groove 101, the bending head 31 can bend the fixed ring in the corresponding bending clearance groove 102.

[0033] The bending process is roughly as follows: with the left end as the feeding end and the right end as the picking end, the fixing ring is placed into the tooling seat 12, and the conveyor belt is controlled to rotate in a directional manner to feed the tooling seat 12 with the fixing ring to the right. When the positioning sensor 23 detects that the fixing ring is in place, the conveyor belt 11 is controlled to stop rotating, and the pressing head 22 is pressed down to the top of the fixing ring to press the fixing ring. Then the bending head 31 extends and bends the fixing ring through the corresponding bending clearance groove 102. After bending in place, it retracts, the pressing head 22 retracts, the bending action is completed, and then the next cycle is performed.

[0034] The tooling seat 12 can be evenly or unevenly distributed on the surface of the conveyor belt 11. Before pressing and bending, the fixed ring to be bent can be placed in the fixed ring placement groove 101 in advance. After bending, the finished fixed ring can be removed manually or automatically (by a robotic arm) so that the tooling seat 12 can make room for the fixed ring after rotating half a turn from the bottom to return to the feeding end. Therefore, the feeding of the bending mechanism is more convenient, and the feeding is less likely to affect the normal pressing and bending operation, resulting in higher work efficiency.

[0035] In one embodiment, the mounting bracket 21 includes uprights 211 symmetrically distributed on both sides of the conveyor belt 11 and mounting plates 212 connected to the top of the two uprights 211. The clamping mechanism 20 also includes a clamping cylinder 24 mounted on the mounting plate 212. The clamping cylinder 24 has a bottom telescopic shaft, and the clamping head 22 is fixedly mounted on the bottom telescopic shaft, so that the clamping head 22 can be moved up and down in a directional manner by the clamping cylinder 24. The positioning sensor 23 is mounted on the mounting plate 212.

[0036] In one embodiment, the bottom end of the bottom telescopic shaft is vertically connected to an adapter plate 25, and the pressing head 22 is installed at the bottom of the adapter plate 25. In addition, the bottom of the adapter plate 25 is symmetrically equipped with positioning pins 26 on the outside of the pressing head 22, and the positioning pins 26 protrude from the pressing head 22 below. Correspondingly, the top of the tooling base 12 is provided with a positioning hole 103 that cooperates with the positioning pin 26. In this way, before the pressing head 22 presses the fixed ring, the positioning pin 26 first positions the tooling base 12 through the positioning hole 103, that is, secondary positioning (where the directional rotation of the conveyor belt 11 is primary positioning). This ensures that the pressing head 22 is accurately pressed on the surface of the fixed ring, thereby avoiding the problem of the fixed ring shifting during the pressing process, and thus ensuring the bending quality of the fixed ring.

[0037] In one embodiment, the mounting plate 212 has mounting holes 201 at both ends that mate with the column 211, and linear holes 202 distributed on both sides of the mounting holes 201. The linear holes 202 near the ends are open holes. Simultaneously, locking screws 27 perpendicularly penetrating the open holes are installed at both ends of the mounting plate 212. After loosening or removing the locking screws 27, the mounting plate 212 can move up and down along the column 211. Once in position, the locking screws 27 compress the linear holes 202, thereby fixing the mounting plate 212 at a predetermined height position on the column 211. This allows for flexible adjustment of the height position of the mounting plate 212, the clamping cylinder 24, and the positioning sensor 23, facilitating the clamping of products at different heights and providing greater flexibility in use.

[0038] In one embodiment, a rotary motor 13 and two fixed plates 14 are mounted on the top of the base plate 10. The two fixed plates 14 are symmetrically distributed on both sides of the conveyor belt 11 and connected to a conveyor belt support 15. The fixed plates 14 are supported and fixed at the bottom by support columns or support plates 16. The bending mechanism 30 is mounted on the top of the fixed plates 14. In addition, a drive wheel 17 and a driven wheel 18 are respectively mounted on opposite ends of the conveyor belt support 15. The conveyor belt 11 is wound between the drive wheel 17 and the driven wheel 18. The rotating shaft of the rotary motor 13 is fixedly sleeved with a rotating wheel 131, and the rotating wheel 131 is connected to the drive wheel 17 through a transmission belt 132. The rotary motor 13 drives the rotary wheel 131 to rotate via the rotary shaft. The rotary wheel 131 drives the drive wheel 17 to rotate synchronously via the transmission belt 132. Under the transmission connection of the conveyor belt 11, the driven wheel 18 rotates passively. Thus, the rotary motor 13 can drive the conveyor belt 11 to rotate in a specific direction. The transmission belt 132 can also be a transmission chain. The corresponding rotary wheel 131, drive wheel 17, and driven wheel 18 are gears. The inner surface of the conveyor belt 11 is provided with toothed grooves. The conveyor belt 11 is not only wound around the drive wheel 17 and the driven wheel 18, but also around the conveyor belt support 15. That is, the position between the drive wheel 17 and the driven wheel 18 can be supported by the conveyor belt support 15. When the fixed ring is tightened or bent, the conveyor belt support 15 can provide good support.

[0039] In one embodiment, combined Figure 5 The bending and positioning grooves 102 are distributed in a cross shape on the side wall of the fixed ring placement groove 101. At the same time, there are four bending mechanisms 20, which are symmetrically distributed on both sides of the conveyor belt 11 and are respectively aligned with each bending and positioning groove 102 when the tooling seat 12 moves into place.

[0040] In one embodiment, combined Figure 6 The bending mechanism 30 includes an L-shaped mounting plate 32 and a bending cylinder 33. The L-shaped mounting plate 32 includes a vertical plate 321 at one end away from the conveyor belt 11. The bending cylinder 33 is mounted on the outer side of the vertical plate 321, and the output shaft of the bending cylinder 33 passes vertically through the vertical plate 321. The bending head 31 is mounted at the end of the output shaft of the bending cylinder 33. Thus, the bending cylinder 33 drives the bending head 31 to move horizontally, extending the bending fixing ring outward or retracting it inward.

[0041] More preferably, the L-shaped mounting plate 32 further includes a horizontal plate 322 near one end of the conveyor belt 11, wherein the top of the horizontal plate 322 is provided with a guide rail 323, and the guide rail 323 extends along the extension and retraction direction of the output shaft of the bending cylinder 33. Correspondingly, a slider 34 that slides with the guide rail 323 is connected between the bending head 31 and the output shaft of the bending cylinder 33. In this way, during the bending process of the bending head 31 bending the fixed ring, the cooperation between the slider 34 and the guide rail 323 can ensure the accuracy of the movement direction of the bending head 31, thereby ensuring the bending quality.

[0042] In one embodiment, the top of the horizontal plate 322 is symmetrically provided with limit plates 324 on both sides of the bending head 31, and the slider 34 is connected with an adjusting screw 341. The adjusting screw 341 extends along the extension and retraction direction of the output shaft of the bending cylinder 33 and is respectively facing the limit plate 324. In this way, the angle of the fixed ring after bending can be controlled by adjusting the length of the screw 341 protruding from the slider 34, that is, the relative distance between the screw 341 and the limit plate 324. Specifically, in the initial working state, the bending cylinder 33 drives the slider 34 and the bending head 31 to move the bending fixing ring inward. When the adjusting screw 341 reaches the limit plate 324, it means that the bending is in place. When it is necessary to adjust the bending angle, the adjusting screw 341 can be rotated to move it closer to or further away from the limit plate 324. After the adjustment is in place, when the bending cylinder 33 runs again, the bending is still considered to be in place when the adjusting screw 341 reaches the limit plate 324. However, the extension length of the bending head 31 has changed accordingly, thus achieving the function of adjusting the bending angle.

[0043] In one embodiment, a protective cover 19 is installed on the top of the base plate 10, wherein the protective cover 19 extends along the conveying direction of the conveyor belt 11, and both ends of the conveyor belt 11 protrude from the protective cover 19. The pressing mechanism 20 and the bending mechanism 30 are both located inside the protective cover 19, thereby protecting the pressing mechanism 20 and the bending mechanism 30 by the protective cover 19 and preventing external impurities from affecting the bending quality.

[0044] In addition, a transmission belt protective cover 111 is installed on the top of the base plate 10. It is L-shaped and is used to protect the transmission belt 132 from the top and the outside, respectively, so as to ensure the transmission accuracy of the transmission belt 132.

The advantages of the present invention have been fully and effectively realized.
