[0046] The utility model provides a battery cover plate assembly and fixing device, which is suitable for application scenarios of battery assembly production and can clamp and fix the battery cover plate and two battery cell monomers to complete welding operations.

[0047] See also Figure 1 The cell cover assembly and fixing device provided in this embodiment includes a main fixture assembly 1 and a transfer assembly 2 for conveying the main fixture assembly 1. Specifically, the transfer assembly 2 is a circular structure, which can drive the main fixture assembly 1 to cyclically move.

[0048] Along the feeding direction of the transfer component 2, there are sequentially provided a first main clamping component 3a for opening the main clamping component 1 to place the first battery cell, a second main clamping component 3b for opening the main clamping component 1 to place the battery cover, and a third main clamping component 3c for opening the main clamping component 1 to place the second battery cell.

[0049] See also Figure 2 The main clamp assembly 1 includes a clamp base 101 , a fixed clamp plate 102 , a movable clamp plate 103 , a clamp spring, and a side clamp assembly 104 .

[0050] The fixed clamping plate 102 is fixed on the clamp base 101 and is provided with a cover plate slot 1021 for inserting the end position of the battery cover. The movable clamping plate 103 is slidably connected to the clamp base 101. One end of the clamp spring is connected to the clamp base 101, and the other end is connected to the movable clamping plate 103, driving the movable clamping plate 103 to slide relative to the clamp base 101 toward the fixed clamping plate 102.

[0051] The first main clamping assembly 3a, the second main clamping assembly 3b and the third main clamping assembly 3c all include an XYZ three-way module and a clamping latch connected to the driving end of the XYZ three-way module.

[0052] See also Figure 2 to Figure 4 , in order to facilitate the distinction:

[0053] The XYZ three-way module of the first main clamp opening assembly 3a is recorded as "XYZ three-way module 301a", and the clamp opening latch of the first main clamp opening assembly 3a is recorded as "clamp opening latch 302a";

[0054] The XYZ three-way module of the second main clamp opening assembly 3b is recorded as "XYZ three-way module 301b", and the clamp opening latch of the second main clamp opening assembly 3b is recorded as "clamp opening latch 302b";

[0055] The XYZ three-way module of the third main clamp opening assembly 3c is referred to as “XYZ three-way module 301c”, and the clamp opening latch of the third main clamp opening assembly 3c is referred to as “clamp opening latch 302c”.

[0056] The axes of the clamping opening latch 302a and the clamping opening latch 302c are both perpendicular to the sliding direction of the movable clamping plate 103; and the movable clamping plate 103 is provided with a latch hole 1031 for the clamping opening latch 302a and the clamping opening latch 302c to be inserted.

[0057] See also Figure 3 The axis of the clamping pin 302b of the second main clamping assembly 3b is parallel to the sliding direction of the movable clamping plate 103 and is located on the side of the movable clamping plate 103 close to the fixed clamping plate 102.

[0058] See also Figure 5 The side clamp assembly 104 is used to clamp the tabs of the battery cell, and specifically includes a pressure plate shaft 1041 , a tab pressure plate 1042 , and a pressure plate tension spring 1043 .

[0059] The pressing plate rotating shaft 1041 is horizontally mounted on the clamp base 101. The tab pressing plate 1042 is connected to the clamp base 101 through the pressing plate rotating shaft 1041. One end of the pressing plate tension spring 1043 is fixed to the tab pressing plate 1042, and the other end is fixed to the base side fixing portion 1011 of the clamp base 101. The pressing plate tension spring 1043 has a pre-tightening force to play a tensioning role, thereby tightening the tab pressing plate 1042, so that the tab pressing plate 1042 can maintain an open clamping state (the tab pressing plate 1042 is vertical) to release the tab or maintain a clamping state (the tab pressing plate 1042 is horizontal) to clamp the tab after an external force acts.

[0060] The battery cover assembly and fixing equipment also includes a side clamping assembly 4 for switching the pressure plate tension spring 1043 to a clamped state and a side opening clamping assembly 5 for switching the pressure plate tension spring 1043 to an open state, and a welding station 6 for placing welding equipment is provided between the side clamping assembly 4 and the side opening clamping assembly 5.

[0061] See also Figure 6 The side clamping assembly 4 includes a clamping roller 401 and a clamping linear driving mechanism 402 for driving the clamping roller 401 to reciprocate in the vertical direction; see Figure 7 The side opening and clamping assembly 5 includes an opening and clamping roller 501 and an opening and clamping linear driving mechanism 502 for driving the opening and clamping roller 501 to reciprocate in a horizontal direction.

[0062] At the beginning, the side clamp assembly 104 is in an open clamp state. The battery cover assembly and fixing device provided in this embodiment has the following working process:

[0063] S10: The XYZ three-way module 301a of the first main clamping assembly 3a drives the clamping pin 302a to be inserted into the pin hole 1031 of the movable clamping plate 103, and then drives the movable clamping plate 103 to move away from the fixed clamping plate 102, thereby opening the main clamping assembly 1 for the first time;

[0064] S20: The first battery cell is placed between the fixed clamping plate 102 and the movable clamping plate 103. The XYZ three-way module 301a of the first main clamping assembly 3a drives the clamping pin 302a to disengage from the pin hole 1031 of the movable clamping plate 103. Under the driving action of the clamp spring, the movable clamping plate 103 moves toward the fixed clamping plate 102 and cooperates with the fixed clamping plate 102 to clamp the first battery cell.

[0065] S30: The transfer assembly 2 transfers the main clamp assembly 1 to the second main opening clamp assembly 3b, and the XYZ three-way module 301b of the second main opening clamp assembly 3b drives the opening clamp pin 302b to push the first battery cell monomer in a direction away from the fixed clamp plate 102, so that the first battery cell monomer drives the movable clamp plate 103 to move in a direction away from the fixed clamp plate 102, thereby opening the main clamp assembly 1 again;

[0066] S40: The battery cover is placed into the cover slot 1021 of the fixed clamping plate 102. Then, the second main clamping assembly 3b releases the first battery cell. Under the driving action of the clamp spring, the movable clamping plate 103 moves toward the fixed clamping plate 102 and cooperates with the fixed clamping plate 102 to clamp the first battery cell and the battery cover.

[0067] S50: the transfer assembly 2 transfers the main clamp assembly 1 to the third main clamp opening assembly 3c, and the XYZ three-way module 301c of the third main clamp opening assembly 3c drives the clamp opening latch 302c to be inserted into the latch hole 1031 of the movable clamp plate 103, and then drives the movable clamp plate 103 to move away from the fixed clamp plate 102, thereby opening the main clamp assembly 1 for the third time;

[0068] S60: Put the second battery cell between the fixed clamping plate 102 and the movable clamping plate 103 (at this time, the second battery cell is stacked on the first battery cell), and the XYZ three-way module 301c of the third main clamping assembly 3c drives the clamping pin 302c to disengage from the pin hole 1031 of the movable clamping plate 103. Under the driving action of the clamp spring, the movable clamping plate 103 moves toward the fixed clamping plate 102 and cooperates with the fixed clamping plate 102 to clamp the first battery cell, the second battery cell and the battery cover;

[0069] S70: The transfer assembly 2 transfers the main clamp assembly 1 to the side clamp assembly 4. At this time, the tab pressing plate 1042 is in a horizontal state, and the outer end of the tab pressing plate 1042 is directly above the clamping roller 401. The clamping linear drive mechanism 402 drives the clamping roller 401 to move upward, so that the tab pressing plate 1042 can be rotated to a vertical state, and the tabs on the sides of the two battery cell monomers are pressed tightly under the tension of the pressure plate tension spring 1043;

[0070] S80: The transfer assembly 2 transfers the main fixture assembly 1 to the welding station 6, and the welding equipment performs welding operation on the tab;

[0071] S90: The transfer assembly 2 transfers the main clamp assembly 1 to the side opening clamp assembly 5. At this time, the tab pressing plate 1042 is in a vertical state, and the lower end of the tab pressing plate 1042 is at the side of the opening clamp roller 501. The opening clamp linear drive mechanism 502 drives the closing clamp roller 401 to be horizontally close to the lower end of the tab pressing plate 1042, so that the tab pressing plate 1042 can be rotated to a horizontal state to release the tabs on the sides of the two battery cell monomers.

[0072] S100: The transfer assembly 2 continues to move the main clamp assembly 1 downstream to perform other processes.

[0073] To sum up, the battery cover assembly and fixing equipment provided in this embodiment has the following advantages: the first main clamping component 3a, the second main clamping component 3b, and the third main clamping component 3c open the main clamping component 1 in sequence, and can sequentially insert the first battery cell, the battery cover and the second battery cell, thereby clamping and fixing the battery cover and the two battery cells to complete the welding operation.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
