Detailed Implementation

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0052] Example 1

[0053] like Figure 1-10 As shown, the present invention proposes a battery pack assembly fixing device, including a frame, and further including a limiting guide component, a lateral drive component, a lateral limiting component, a longitudinal limiting component, and an impurity removal component. The limiting guide component is disposed on the frame, the lateral drive component is disposed on the frame, one side of the lateral drive component is connected to the limiting guide component, and the lateral limiting component is connected to the lateral drive component. The lateral limiting component can limit the battery pack under the drive of the lateral drive component. The longitudinal limiting component is disposed on the lateral limiting component and limits the longitudinal direction of the battery pack. The impurity removal component is disposed on the frame and removes impurities.

[0054] In this embodiment, the limiting guide assembly includes a limiting guide rail 110 and a slider 120. The limiting guide rail 110 is provided in pairs and is symmetrically arranged on the frame. The slider 120 is provided in two pairs and is arranged on the frame. The slider 120 is slidably connected to the limiting guide rail 120 and the top surface of the slider is higher than the top surface of the frame.

[0055] In this embodiment, the lateral drive assembly includes a lateral drive motor 210, a bidirectional lead screw 220, a movable bracket 230, and a guide rod 240. The lateral drive motor is mounted on the frame, with its rotating end facing the frame. The bidirectional lead screw is rotatably mounted on the frame, with one side connected to the lateral drive motor. The bidirectional lead screw can rotate under the drive of the lateral drive motor. A pair of movable brackets are provided, each threadedly connected to both sides of the bidirectional lead screw. The bottom of the movable bracket is connected to the top of the slider. Sliding grooves 231 are provided on both sides of the movable bracket. Two pairs of guide rods are provided, each guide rod being disposed in one of the sliding grooves of the movable bracket.

[0056] In this embodiment, the lateral limiting assembly includes a lateral limiting plate 310 and a limiting spring 320. A pair of lateral limiting plates are provided, with both sides slidably disposed in the sliding grooves of the movable bracket. Each side of the lateral limiting plate is slidably connected to a guide rod, thus fixing the battery pack. The limiting spring is sleeved on the guide rod, with one side abutting against the lateral limiting plate and the other side abutting against the sliding groove of the movable bracket. By using the limiting spring to limit the lateral limiting plate, after the lateral limiting plate contacts the battery, it compresses the limiting spring, causing the spring to deform and generate a reaction force. This ensures the lateral limiting plate abuts against the battery pack, effectively preventing damage to the battery due to clamping distance inaccuracies or excessive clamping force, thereby increasing the battery yield.

[0057] In this embodiment, the longitudinal limiting assembly includes a second limiting guide rail 410, a moving block 420, a limiting bolt 430, and a longitudinal limiting plate 440. The second limiting guide rail is provided in pairs and is disposed on the transverse limiting plate. The second limiting guide rail has a moving space. Two pairs of moving blocks are provided, slidably disposed on the second limiting guide rail. Each moving block has a threaded hole. Two pairs of limiting bolts are provided, threadedly engaged in the threaded holes of the moving blocks. The bottom of each limiting bolt is movable and abuts against the second limiting guide rail, thereby limiting the movement of the moving blocks. The movable block is fixed, and the longitudinal limiting plate is set on the movable block. The longitudinal limiting plate limits the longitudinal movement of the battery pack. When it is necessary to adjust the position of the movable block during operation, simply loosen the limiting bolt so that the bottom of the limiting bolt no longer abuts against the limiting guide rail 2, thereby adjusting the position of the movable block. After the position of the movable block is adjusted, tighten the limiting bolt again to complete the adjustment of the position of the longitudinal movable plate. It is worth noting that the position adjustment of the longitudinal limiting plate is manual, so there will be no situation where the battery is damaged due to excessive clamping force or error in clamping distance.

[0058] Example 2

[0059] like Figure 1-10 As shown, the difference between this embodiment and Embodiment 1 is that, in this embodiment, the impurity removal component includes a negative pressure fan 510, a collection box 520, a filter plate 530, a suction duct 540, and a dust removal pipe 550. The negative pressure fan is located on one side of the frame, the collection box is located on one side of the negative pressure fan, the filter plate is slidably disposed in the collection box, and the filter plate filters impurities. A handle is provided on the top of the filter plate. One side of the suction duct 540 is connected to the suction end of the negative pressure fan, and the other side of the suction duct 550 is connected to the collection box. The suction duct 550 is located on the side of the negative pressure fan. On the left side of the filter plate, one side of the dust removal pipe is connected to the collection box. The dust removal pipe is located on the right side of the filter plate and is equipped with a diversion section 551. The diversion section is symmetrically arranged on both sides of the frame. The dust removal pipe collects impurities. During battery pack assembly, many impurities float in the air. These impurities will adhere to the battery pack during the floating process, thus affecting the accuracy of the battery pack. This device removes impurities around the battery pack through the dust removal pipe, thereby effectively preventing impurities from adhering to the battery pack, thus effectively increasing the accuracy of the battery pack after assembly and increasing the quality of the battery pack.

[0060] The working principle of this utility model:

[0061] During processing, multiple batteries are placed on the frame. The limit bolts abutting against the second limit guide rail are loosened. The moving block is moved, causing the longitudinal limit plates to move along the second limit guide rail. The longitudinal limit plates move to both sides of the battery, thus limiting the two sides of the battery pack. Then, the limit bolts are tightened so that the bottom of the limit bolts abuts against the second limit guide rail, thus fixing the moving block. Then, the transverse drive motor drives the bidirectional lead screw to rotate. As the bidirectional lead screw rotates, it drives the moving brackets to move closer together through the threaded engagement. The moving brackets drive the transverse limit plates to move towards the battery, and the transverse limit plates move towards both sides of the battery. Upon contact, the lateral limiting plate compresses the limiting spring, causing the spring to deform under force and generate a reaction force. This causes the lateral limiting plate to abut against both sides of the battery, thus securing the battery. Simultaneously, during battery assembly, the negative pressure fan is activated, drawing air out of the collection box and creating a negative pressure. Impurities in the air are then drawn into the collection box through a dust removal pipe, filtered by the filter screen within the box, and stored there. The filtered gas is then drawn out and discharged by the negative pressure fan before the battery pack is assembled, ensuring the quality of the battery pack assembly.
