Description

Technical Field

[0001] The present invention relates to the technical field of battery cell assembly, and particularly to an automatic installation mechanism for battery pack cell connectors. Background Art

[0002] Most existing battery pack cells are grouped by locking screws or by cell BSB welding process to form a module or a cell Block unit, and then assembled into a battery pack. After assembly, the heat dissipation effect of the battery is poor, there is a risk of poor welding, and disassembly and repair are inconvenient. When repairing, the entire battery module or cell Block needs to be replaced together, which is relatively costly in terms of repair, will cause waste of some cell materials, and will also cause environmental pollution to a certain extent.

[0003] To avoid the above situations, existing battery cells also connect the busbar connectors in series to the poles on each cell in the battery module. However, for this connection method, after the operator manually places the busbar connector at the position of the pole where the cell needs to be connected, the connection can be achieved by locking the screw tightly. This connection method requires a large number of repeated operations by the operator to place the busbar connector during assembly, and its efficiency is extremely low. At the same time, during assembly of this connection method, a positioning block is also required to position the connector. Therefore, after the connection is completed, the positioning block of the connector needs to be bent and snapped into the clamping groove of the pole, which further reduces the production speed of the battery module. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide an automatic installation mechanism for battery pack cell connectors, which can achieve batch automated assembly of cell busbar connectors without using a positioning block for positioning, and greatly improves the assembly efficiency.

[0005] An automatic installation mechanism for a battery pack cell connection member includes an installation frame, a fixture seat, fixtures, an X-direction adjustment mechanism, and a Y-direction adjustment mechanism disposed above the cells. A plurality of cells are evenly distributed in the X direction, and the positive and negative electrodes of adjacent cells are staggered. The cells are alternately connected in series through a first bus bar connection member and a second bus bar connection member. The first bus bar connection member is located on one side in the width direction of the cell, and the second bus bar connection member is located on the other side in the width direction of the cell. The fixtures include a first fixture corresponding to and clamping with each first bus bar connection member and a second fixture corresponding to and clamping with each second bus bar connection member. The fixture seat includes a first fixture seat connected to the first fixture and a second fixture seat connected to the second fixture. The first fixture seat and the second fixture seat are both movably disposed in the installation frame. The X-direction adjustment mechanism connects the first fixture seat and the second fixture seat and can synchronously displace the first fixture seat and the second fixture seat in the X direction. The Y-direction adjustment mechanism is used to drive the first fixture seat and the second fixture seat to move away from or towards each other. Among them, the X direction is the thickness direction of the cell, and the Y direction is the width direction of the cell.

[0006] Through the above technical solutions, the fixtures on both sides can respectively clamp the first bus bar connection member and the second bus bar connection member, and synchronously perform displacement in the X direction and the Y direction under the drive of the X-direction adjustment mechanism and the Y-direction adjustment mechanism, so that the first bus bar connection member and the second bus bar connection member can fall into the specified positions. Subsequently, only by tightening the locking screws of the pole columns can the series assembly of the cells be realized. This installation mechanism can be applied to the assembly of cell connection members of any specification, and can realize the batch automatic assembly of the connection members, greatly improving the efficiency. At the same time, since the X-direction adjustment mechanism and the Y-direction adjustment mechanism can realize the synchronous adjustment of each connection member at any position, the assembly consistency is high, and the assembly position can be accurately guaranteed through automatic precise control, so there is no need to use positioning blocks to position the position of the connection members, further improving the assembly efficiency.

[0007] Preferably, both the first fixture seat and the second fixture seat include a height adjustment mechanism, a top mounting seat, and a bottom mounting seat for connecting the fixture. One end of the height adjustment mechanism is connected to the top mounting seat, and the other end is connected to the bottom mounting seat. The X-direction adjustment mechanism and the Y-direction adjustment mechanism are connected to the first fixture seat or the second fixture seat through the top mounting seat. Integrating the height adjustment mechanism on the fixture seat can realize the automatic lifting of the fixture and make the control more flexible.

[0008] More preferably, the X-direction adjusting mechanism includes an X-direction driving member, an X-direction telescopic member, an X-direction sliding rod, a slider, and a Y-direction sliding rod. The X-direction driving member is fixedly connected to the X-direction telescopic member and can drive the X-direction telescopic member to displace along the X direction. X-direction sliding rods extending along the X direction are provided at both sides inside the installation frame. Each of the first fixture seats is slidably engaged with one of the X-direction sliding rods through a fixedly connected slider, and each of the second fixture seats is slidably engaged with the other X-direction sliding rod through a fixedly connected slider. A number of first connection parts and second connection parts are alternately arranged along the X direction on the X-direction telescopic member. The X-direction telescopic member is connected to the slider of the first fixture seat through the first connection part, and the second connection part of the X-direction telescopic member is connected to the second fixture seat through the Y-direction sliding rod.

[0009] With the above structure, a single-sided X-direction driving member can be used to achieve synchronous driving of the bilateral fixtures, which greatly simplifies the structure of the X-direction adjusting mechanism and saves the space it occupies. Moreover, through this delicate design, synchronous driving of all fixtures in the X direction is achieved, ensuring the consistency of the assembly of the connecting parts.

[0010] More preferably, the X-direction telescopic member is a cross-type fence telescopic member. The cross-type fence telescopic member includes a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod cross and are hinged to each other in the middle, and the first connecting rod and the second connecting rod are hinged to each other at the top and bottom ends. The first connection part is the middle hinge point, and the second connection part is the top hinge point.

[0011] More preferably, the Y-direction adjusting mechanism includes a Y-direction driving member and a gear transmission member. A bracket is fixedly connected to the top of the second fixture seat, and a vertical sliding groove slidably engaged with the Y-direction sliding rod is provided on the bracket. The gear transmission member is used to drive the X-direction sliding rods on both sides to move away from or towards each other along the Y-direction sliding rod.

[0012] More preferably, connection blocks are fixedly connected to both ends of the X-direction sliding rod. The gear transmission member includes a gear driven by a motor, a first rack meshing with the upper part of the gear, and a second rack meshing with the lower part of the gear. The ends of the first rack and the second rack are respectively fixedly connected to the connection blocks on both sides.

[0013] With the above structure, combined with the Y-direction sliding rod, synchronous displacement of the bilateral fixtures in the Y direction can be achieved, so as to flexibly adjust the distance between the fixtures in the width direction, enabling the mechanism to be applicable to the assembly of various models of battery cells and improving the universality of the mechanism. At the same time, with the above structure, the Y-direction adjusting mechanism and the X-direction adjusting mechanism can be located in two different areas of the installation frame (one is the end part and the other is the side part), so as to realize the layout in a narrow space and avoid mutual interference between the Y-direction adjusting mechanism and the X-direction adjusting mechanism.

[0014] More preferably, the height adjustment mechanism includes a cylinder, the cylinder block of the cylinder is fixed to the top mounting seat, and the piston rod of the cylinder extends downward and is fixed to the bottom mounting seat.

[0015] More preferably, both the first fixture and the second fixture include a clamping body that opens and closes in the Y direction. The bottom of the clamping body is provided with a downwardly extending slot that penetrates in the X direction at the central position. The top wall and side wall of the downwardly extending slot are in limiting cooperation with the upper surface and side of the busbar connector. The design of the clamping body of this structure can assist in limiting the height and width directions of the connector through the downwardly extending slot, further ensuring the assembly accuracy.

[0016] More preferably, the mounting frame is a square frame with a hollow interior and openings at the top and bottom.

[0017] More preferably, the X-direction slide bar is a double-slide bar structure arranged vertically in the height direction.

[0018] The beneficial effects of the present invention are as follows: The two-side fixtures of this mechanism can respectively clamp the first busbar connector and the second busbar connector, and synchronously perform X-direction and Y-direction displacements under the drive of the X-direction adjustment mechanism and the Y-direction adjustment mechanism, so that the first busbar connector and the second busbar connector can fall into the designated positions. Subsequently, the staff only needs to tighten the locking screws of the pole columns to achieve the series assembly of the battery cells. This installation mechanism can be applied to the assembly of battery cell connectors of any specification, and can realize the batch automatic assembly of the connectors, greatly improving the efficiency. At the same time, since the X-direction adjustment mechanism and the Y-direction adjustment mechanism can realize the synchronous adjustment of each connector at any position, the assembly consistency is high, and the assembly position can be accurately guaranteed through automatic precision control, so there is no need to use positioning blocks to position the connector positions, further improving the assembly efficiency.

[0028] Embodiment 1

[0029] Figures 1-4 The schematic structural diagram of an automatic installation mechanism for a battery pack cell connector provided by a preferred embodiment of the present application is shown. For the convenience of description, only the parts related to this embodiment are shown and are described in detail as follows:

[0030] As Figure 1 , 2As shown in the figure, an automatic installation mechanism for battery pack cell connectors includes an installation frame 1, a fixture base, fixtures, an X-direction adjustment mechanism, and a Y-direction adjustment mechanism arranged above the cells 2. A plurality of cells 2 are evenly distributed along the X-direction, and the positive and negative electrodes of adjacent cells 2 are arranged staggeredly. Each cell 2 has a positive electrode and a negative electrode. The staggered arrangement of the positive and negative electrodes means that cells 1, 3, 5,... are placed with the positive electrode facing forward and the negative electrode facing backward, and cells 2, 4, 6,... are placed with the negative electrode facing forward and the positive electrode facing backward. The cells 2 are alternately connected in series through a first busbar connector 5 and a second busbar connector 6. The first busbar connector 5 is located on one side of the cell 2 in the width direction, and the second busbar connector 6 is located on the other side of the cell 2 in the width direction. That is, the positive electrode of a certain cell is connected to the negative electrode of the previous cell through the first busbar connector 5, and the negative electrode is connected to the positive electrode of the next cell through the second busbar connector 6. Connecting in this alternating manner can achieve the series connection of all cells in the X-direction to form a group.

[0031] The fixtures include a first fixture 3 corresponding to and clamping with each first busbar connector 5 and a second fixture 4 corresponding to and clamping with each second busbar connector 6. The fixture base includes a first fixture base 7 connected to the first fixture 3 and a second fixture base 8 connected to the second fixture 4. The first fixture base 7 and the second fixture base 8 are both movably arranged in the installation frame 1. The X-direction adjustment mechanism is connected to the first fixture base 7 and the second fixture base 8 and can synchronously displace the first fixture base 7 and the second fixture base 8 along the X-direction. The Y-direction adjustment mechanism is used to drive the first fixture base 7 and the second fixture base 8 to move away from or towards each other. Among them, the X-direction is the thickness direction of the cell 2, and the Y-direction is the width direction of the cell 2. The fixtures on both sides can respectively clamp the first busbar connector and the second busbar connector, and under the drive of the X-direction adjustment mechanism and the Y-direction adjustment mechanism, they can synchronously perform X-direction and Y-direction displacements, so that the first busbar connector and the second busbar connector can fall into the specified positions. Subsequently, only by tightening the locking screws of the pole columns can the series connection and assembly of the cells be achieved. This installation mechanism can be applied to the assembly of cell connectors of any specification and can achieve batch automatic assembly of the connectors, greatly improving the efficiency. At the same time, since the X-direction adjustment mechanism and the Y-direction adjustment mechanism can synchronously adjust each connector to any position, the assembly consistency is high. Through automatic precision control, the assembly position can be guaranteed to be accurate, so there is no need to use positioning blocks to position the connectors, further improving the assembly efficiency.

[0032] In one embodiment, as Figure 3As shown, the first fixture base 7 and the second fixture base 8 both include a height adjustment mechanism 20, a top mounting base 21, and a bottom mounting base 22 for connecting the fixture. One end of the height adjustment mechanism 20 is connected to the top mounting base 21, and the other end is connected to the bottom mounting base 22. The X-direction adjustment mechanism and the Y-direction adjustment mechanism are connected to the first fixture base 7 or the second fixture base 8 through the top mounting base 21.

[0033] In one embodiment, the X-direction adjustment mechanism includes an X-direction driving member 28, an X-direction telescopic member 11, an X-direction sliding rod 9, a slider 19, and a Y-direction sliding rod 10. The X-direction driving member 28 is fixedly connected to the X-direction telescopic member 11 and can drive the X-direction telescopic member 11 to displace in the X direction. The X-direction sliding rods 9 extending in the X direction are provided on both sides inside the mounting frame 1. Each first fixture base 7 is slidably engaged with one of the X-direction sliding rods 9 through a fixedly connected slider 19. Each second fixture base 8 is slidably engaged with the other X-direction sliding rod 9 through a fixedly connected slider 19. A plurality of first connection portions 26 and second connection portions 27 are alternately arranged in the X direction on the X-direction telescopic member 11. The X-direction telescopic member 11 is connected to the slider 19 of the first fixture base 7 through the first connection portion 26. The second connection portion 27 of the X-direction telescopic member 11 is connected to the second fixture base 8 through the Y-direction sliding rod 10.

[0034] In one embodiment, as Figure 4 shown, the X-direction telescopic member 11 is a cross-type fence telescopic member. The cross-type fence telescopic member includes a first connecting rod 24 and a second connecting rod 25. The first connecting rod 24 and the second connecting rod 25 cross and are hinged to each other in the middle. The first connecting rod 24 and the second connecting rod 25 are hinged to each other at the top and bottom ends. The first connection portion 26 is the middle hinge point, and the second connection portion 27 is the top hinge point. When the cross-type fence telescopic member is driven to expand and contract by the X-direction driving member 28, the first connection portion 26 drives each slider 19 to move synchronously. At the same time, the second connection portion 27 drives each Y-direction sliding rod 10 to move synchronously, thereby driving each second fixture base 8 connected to the Y-direction sliding rod 10 to move synchronously. With the above structure, combined with the Y-direction sliding rod, the Y-direction synchronous displacement of the bilateral fixtures can be realized, so as to flexibly adjust the distance between the fixtures in the width direction. The flexible displacement in the X direction can realize the adjustment of the distance between the fixtures in the thickness direction of the battery cell, so as to be applicable to the assembly of battery cells with different thicknesses. This enables the mechanism to be applicable to the assembly of various models of battery cells and improves the universality of the mechanism.

[0035] In one embodiment, the Y-direction adjusting mechanism includes a Y-direction driving member 14 and a gear transmission member. A bracket 12 is fixedly connected to the top of the second fixture base 8. The bracket 12 is an L-shaped bracket, whose horizontal part is fixed to the top of the second fixture base 8, and a vertical chute 13 that slidably cooperates with the Y-direction slide bar 10 is formed on its vertical part. The gear transmission member is used to drive the X-direction slide bars 9 on both sides to move away from or towards each other along the Y-direction slide bar 10.

[0036] In one embodiment, connection blocks 18 are fixedly connected to both ends of the X-direction slide bar 9. The gear transmission member includes a gear 15 driven by a motor, a first rack 16 meshing with the upper part of the gear 15, and a second rack 17 meshing with the lower part of the gear 15. The end parts of the first rack 16 and the second rack 17 are respectively fixedly connected to the connection blocks 18 on both sides. With the above structure, the Y-direction adjusting mechanism and the X-direction adjusting mechanism can be located in two different areas of the installation frame (one is the end part and the other is the side part), so as to realize the layout in a narrow space and avoid mutual interference between the Y-direction adjusting mechanism and the X-direction adjusting mechanism. When the Y-direction driving member 14 drives the gear 15 to rotate forward, under the sliding cooperation of the vertical chute 13 and the Y-direction slide bar 10, the two racks drive the slide bars on both sides to move towards each other. When the Y-direction driving member 14 drives the gear 15 to rotate reversely, under the sliding cooperation of the vertical chute 13 and the Y-direction slide bar 10, the two racks drive the slide bars on both sides to move away from each other. Thus, the distance between the two clamps on both sides can be adjusted to adapt to the assembly of battery cells with different widths.

[0037] In one embodiment, the height adjusting mechanism 20 includes a cylinder. The cylinder block of the cylinder is fixed to the top mounting seat 21, and the piston rod of the cylinder extends downward and is fixed to the bottom mounting seat 22. Through the adjustment of the cylinder, when its piston rod extends or retracts, the lifting control of the fixture can be realized, so as to realize the clamping, placing and separating of the connecting piece.

[0038] In one embodiment, both the first fixture 3 and the second fixture 4 include a clamp body that opens and closes in the Y direction. A lower slot 23 that penetrates in the X direction is provided at the center of the bottom of the clamp body. The top wall of the lower slot 23 is in limit cooperation with the upper surface of the clamped busbar connecting piece. The design of the clamp body with this structure can perform auxiliary limiting on the connecting piece in the height direction and the width direction through the lower slot, further ensuring the assembly accuracy of the connecting piece.

[0039] In one embodiment, the installation frame 1 is a square frame with a hollow interior and open top and bottom.

[0040] In one embodiment, the X-direction slide bar 9 is a double-slide bar structure arranged vertically in the height direction. This double-slide bar structure form can make the stability between the slider and the slide bar higher, so that the fixture will not shake.

[0041] The working process of this device is as follows:

[0042] After the battery cells are placed in place in the manner of alternating positive and negative electrodes described above, the fixture is loosened to form a clamping space. The automatic installation mechanism grabs two columns of busbar connectors from the conveyor belt through each fixture. The X-direction driving member 28 and the Y-direction driving member 14 synchronously drive the cross-shaped fence telescopic member and the gear transmission member to make the distance between the fixtures in the X-direction and the Y-direction reach a suitable position. At this suitable position, the first busbar connector 5 and the second busbar connector 6 are respectively located directly above the positions to be assembled. At this time, the cylinder of the height adjustment mechanism 20 is extended to make the fixture descend. When the clamping grooves of the first busbar connector 5 and the second busbar connector 6 are engaged with the pole columns on the left and right sides, the fixture separates and ascends. The operator can sequentially tighten the locking screws at each pole column.

[0043] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the protection scope of the present application.
