[0044] The rear sliding guide wheel 803 can slide between the front track module 3 and the outer track module 6 , between the middle module 4 and the outer track module 6 , and between the middle module 4 and the rear track module 5 .

[0045] Among them, the transport frame 8 also includes: a trigger support block 804, the main body of the trigger support block 804 is an inverted trapezoidal structure, two groups of spring rods 805 are fixedly arranged on the outside of the trigger support block 804, the spring rods 805 are sleeved with springs and pass through the two sides and middle of the transport frame 8.

[0046] like Figure 1 As shown, the width of the assembly low column 101 is reduced to ensure that the cyclic movement of the transport frame 8 will not be interfered with.

[0047] During the front assembly, the driving motor 105 is started to drive the transmission wheel 104 to rotate, and then the conveyor belt 7 is driven to convey the carbon sheet backwards. The carbon sheet is fed to one station at a time through program control;

[0048] At least two workstations are pre-arranged above the conveyor belt 7;

[0049] The worker places the carbon sheet in the trigger bracket 804 at the front station, and places the film in the flange of the carbon sheet at the rear station, and aligns and installs them, and can bond them as needed;

[0050] During the movement of the transport frame 8:

[0051] The front sliding guide wheel 802 slides between the front track module 3 and the middle module 4, between the middle module 4 and the outer track module 6, and between the rear track module 5 and the outer track module 6;

[0052] The rear sliding guide wheel 803 can slide between the front track module 3 and the outer track module 6, between the middle module 4 and the outer track module 6, and between the middle module 4 and the rear track module 5, forming a stable sliding cycle, ensuring that the transport frame 8 maintains a relatively unchanged position during the movement and ensuring that the carbon sheet always remains level.

[0053] Example 2: Based on Example 1, if the glue assembly method is adopted, it is necessary to recover the excess glue, and a collecting container is set on the top of the middle platform 401. Some batteries are combined with carbon sheets by gluing, and the fallen glue can be carried by the collecting container. More functions can be added as needed, and the middle platform 401 also provides a reinforced connection effect.

[0054] Embodiment 3: Based on Embodiment 1, when the transport frame 8 moves to the rear and moves downward, the triggering bracket 804 simultaneously descends, and the side of the carbon sheet is placed between the guide pole 201 and the movable pole 202;

[0055] When the trigger pulley 806 descends, it contacts the guide cover 203, generating thrust to push the trigger pulley 806 outward, thereby releasing the support of the carbon sheet by the trigger bracket 804. At this time, the carbon sheet naturally slides down following the guidance of the guide upright rod 201 and the movable upright rod 202, and the carbon sheet passes through the screw rod to be overlapped, and the unlocked carbon sheet naturally slides down to be stacked;

[0056] Compared with a robot or similar multi-drive conveying method, this conveying method is synchronous and single, and the tops of the guide poles 201 and the movable poles 202 are guide structures, so the assembly precision requirement is low and it is suitable for low-cost batch assembly.

[0057] Specific usage and function of this embodiment: In the present invention, when assembling the battery, the battery housing is placed above the assembly seat 2, positioned between the guide upright 201 and the movable upright 202, and a locking screw is installed;

[0058] Continue to place the carbon sheet in the upper transport frame 8, align the transport frames 8 on both sides, and then place the carbon sheet in the middle of the shoulder structure of the trigger bracket 804 on both sides to position and place it;

[0059] The driving motor 105 is started to drive the transmission wheel 104 to rotate, and then the conveyor belt 7 is driven to convey the carbon sheet backwards. The carbon sheet is fed to one station at a time through program control;

[0060] At least two workstations are arranged above the conveyor belt 7, the first workstation places the carbon sheet in the trigger bracket 804, and the second workstation places the film in the flange of the carbon sheet for alignment and installation;

[0061] During the movement of the transport frame 8, the front sliding guide wheel 802 slides between the front track module 3 and the middle module 4, between the middle module 4 and the outer track module 6, and between the rear track module 5 and the outer track module 6; the rear sliding guide wheel 803 can slide between the front track module 3 and the outer track module 6, between the middle module 4 and the outer track module 6, and between the middle module 4 and the rear track module 5, forming a stable sliding cycle, ensuring that the transport frame 8 maintains a relatively unchanged position during the movement, ensuring that the carbon sheet always remains horizontal, and avoiding motion interference during the movement;

[0062] When the transport frame 8 moves to the rear and moves downward, the trigger bracket 804 simultaneously descends, and the side of the carbon sheet is placed between the guide pole 201 and the movable pole 202; when the trigger pulley 806 descends, it contacts the guide cover 203, generating thrust to push the trigger pulley 806 outward, thereby releasing the support of the trigger bracket 804 on the carbon sheet, so that the carbon sheet naturally slides down following the guidance of the guide pole 201 and the movable pole 202, and the carbon sheet passes through the screw rod for overlap;

[0063] By repeating the previous process, continuous automatic assembly stacking can be achieved to assemble the battery;

[0064] After a set of batteries are assembled, a nut is installed outside the battery screw to lock the battery, and then the movable vertical rod 202 is removed to remove the entire battery.
