Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery processing technology, specifically to a fixing fixture for PACK battery packaging that adsorbs and prevents pressure damage. Background Technology
[0002] A battery pack, usually referring to a lithium-ion battery pack or battery module, is a manufacturing process for lithium-ion batteries. It involves connecting multiple lithium-ion cells in parallel and series, and is equipped with a battery management system and thermal management system to meet specific voltage, capacity, and safety requirements. The battery module, composed of multiple cells connected in parallel and series, is the core of the battery pack, responsible for storing and releasing electrical energy. The electrical system mainly consists of connecting copper busbars, high-voltage harnesses, low-voltage harnesses, and electrical protection devices. The high-voltage harnesses are used to deliver battery energy to the end load, acting like major arteries, while the low-voltage harnesses are used to transmit detection and control signals in real time, acting like a neural network.
[0003] In lithium battery production, machines are generally used to group and transport lithium batteries. The operation of batteries is accomplished by installing matching grippers on robotic arms. When using existing grippers, they are clamped by fixing on both sides, but strong pressure is required to ensure the stability of the limit, which can easily damage the surface of the battery, thus reducing its practicality. Utility Model Content
[0004] The purpose of this invention is to provide a fixing fixture for PACK battery packaging that adsorbs and prevents pressure damage, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing clamp for PACK battery packaging with adsorption and anti-pressure damage, including a supporting slider with a groove on its lower surface, and a drive motor fixedly connected to the inner wall of the groove of the supporting slider. A transmission screw is installed between the output end of the drive motor and the inner wall of the groove of the supporting slider. Two positioning sliders are installed on the outer surface of the transmission screw. A limit clamp is fixedly connected to the lower surface of the positioning slider. An air pump is fixed to the side surface of the positioning slider. An anti-slip suction cup is fixedly connected to the side surface of the limit clamp. A communicating air groove is provided between the positioning slider and the limiting clamp. A supporting slide rod is installed through the side surface of the limiting clamp. An anti-slip pad is fixedly connected to one end of the supporting slide rod, and a locking slider is fixed to the other end of the supporting slide rod. An opening is provided on the surface of the locking slider, and a locking block is fixed to the inner wall of the opening of the locking slider. A linkage sealing mechanism is provided inside the limiting clamp. The workpiece pushes the anti-slip pad, the supporting slide rod and the locking slider to move, so that the locking block unlocks the linkage slider, which facilitates the spring to drive the linkage slider and the adjusting tooth plate to descend and engage the adjusting gear, which facilitates the rotation and opening of the sealing baffle.
[0006] Preferably, the transmission screw and the support slider are rotatably connected, the threads on the outer surfaces of the two ends of the transmission screw are in opposite directions, the transmission screw and the positioning slider are threadedly connected, and the positioning slider and the support slider are slidably connected.
[0007] With the above technical solution, since the threads at both ends of the transmission screw are in opposite directions, when the drive motor drives the transmission screw to rotate, the two positioning sliders that are threadedly connected to the transmission screw will slide synchronously and in opposite directions along the support slider.
[0008] Preferably, the anti-slip suction cups are arranged horizontally and symmetrically arranged vertically, and the anti-slip suction cups are interconnected, with one side of the anti-slip suction cup connected to the air groove.
[0009] By adopting the above technical solution, the anti-slip suction cups are arranged horizontally and symmetrically, which can adsorb and fix the battery from the top and bottom sides and multiple points in the horizontal direction, increasing the contact area between the suction cups and the battery surface and making the adsorption force distribution more uniform.
[0010] Preferably, the supporting slide rod and the limiting clamp block are slidably connected, a spring is connected between the anti-slip pad and the limiting clamp block, and a rubber anti-slip strip is provided on the surface of the anti-slip pad.
[0011] By adopting the above technical solution, the sliding connection between the support slide rod and the limiting clamp block, together with the spring between the anti-slip pad and the limiting clamp block, allows the anti-slip pad to have a certain buffer stroke when in contact with the battery.
[0012] Preferably, the linkage sealing mechanism includes a linkage slider, which is installed on the inner wall of the cavity of the limiting clamp block. An adjusting toothed plate is fixedly connected to the upper surface of the linkage slider, an adjusting gear is provided on the inner wall of the cavity of the limiting clamp block, and a sealing baffle is installed on the inner wall of the communicating air groove.
[0013] Using the above technical solution, the linkage sealing mechanism can automatically control the opening and closing of the sealing baffle based on whether the battery is clamped in place, thereby realizing the automatic switching of the anti-slip suction cup adsorption function.
[0014] Preferably, the linkage slider and the limiting clamp are slidably connected, and a spring is connected between the linkage slider and the limiting clamp, with the linkage slider passing through the opening of the locking slider.
[0015] By adopting the above technical solution, the sliding connection between the linkage slider and the limit clamp provides a stable motion trajectory for the up and down movement of the linkage slider, ensuring smooth movement during the triggering process and avoiding jamming.
[0016] Preferably, the side surface of the linkage slider is provided with a groove, and the linkage slider and the locking block are engaged. The adjusting tooth plate and the adjusting gear are meshed. The rotating shaft of the adjusting gear is fixedly connected to the rotating shaft of the sealing baffle.
[0017] Using the above technical solution, the groove on the side surface of the linkage slider is engaged with the locking block, which can stably lock the linkage slider in the initial position when not in operation, preventing it from moving unexpectedly due to spring force or external interference, ensuring that the sealing baffle remains closed, and avoiding gas leakage.
[0018] Compared with the prior art, the beneficial effects of this utility model are: the adsorption-resistant and pressure-damage-preventing fixing fixture for PACK battery packaging: 1. The anti-slip suction cup achieves double protection against pressure damage through uniform adsorption and flexible buffering of the anti-slip pad. The anti-slip suction cup is connected to the air pump through the connecting air groove to form a uniform negative pressure, avoiding excessive local pressure. The spring between the anti-slip pad and the limiting clamp can elastically adjust the clamping force. With the rubber anti-slip strip, it can not only clamp stably, but also buffer rigid pressure to prevent damage to the battery shell and internal structure. 2. The reverse thread design at both ends of the transmission screw drives the positioning slider to slide synchronously in the opposite direction, which can flexibly adjust the spacing of the limit clamps to adapt to different sizes of PACK batteries. The anti-slip suction cups are symmetrically arranged horizontally with multiple adsorption points. Combined with the anti-slip effect of the anti-slip pad, it can effectively prevent the battery from shifting during the packaging process and ensure the accuracy of the packaging operation. 3. The linkage sealing mechanism realizes automatic synchronization of adsorption function and clamping action. When the battery pushes the anti-slip pad to trigger the support slide and lock the slider to move, the locking block unlocks the linkage slider. The sealing baffle is opened by adjusting the tooth plate and adjusting the gear transmission. There is no need for manual control of the air circuit, which simplifies the operation process and improves the automation efficiency of battery packaging. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-6 This utility model provides a technical solution: a fixing fixture for PACK battery packaging with adsorption and anti-pressure damage, including a supporting slider 1, a drive motor 2, a transmission screw 3, a positioning slider 4, a limiting clamp 5, an air pump 6, an anti-slip suction cup 7, a connecting air groove 8, a supporting slide rod 9, an anti-slip pad 10, a locking slider 11, a locking block 12, a linkage slider 13, an adjusting toothed plate 14, an adjusting gear 15, and a sealing baffle 16. The supporting slider 1 has a groove on its lower surface, and the drive motor 2 is fixedly connected to the inner wall of the groove of the supporting slider 1. The output end of the drive motor 2 is connected to the supporting slider 1. A transmission screw 3 is installed between the inner walls of the groove. The transmission screw 3 is rotatably connected to the support slider 1. The threads on the outer surfaces of the two ends of the transmission screw 3 are opposite in direction. The transmission screw 3 is threadedly connected to the positioning slider 4, and the positioning slider 4 is slidably connected to the support slider 1. When the drive motor 2 is started, its output end drives the transmission screw 3 to rotate inside the support slider 1. Because the threads at both ends of the transmission screw 3 are opposite and are threadedly connected to the positioning slider 4, the positioning slider 4 slides along the support slider 1, causing the lower limit clamping block 5 to move closer or further away synchronously until the limit clamping block 5 moves to the position that matches the battery size.
[0023] Two positioning sliders 4 are installed on the outer surface of the transmission screw 3. A limit clamp 5 is fixedly connected to the lower surface of the positioning slider 4. An air pump 6 is fixed to the side surface of the positioning slider 4. An anti-slip suction cup 7 is fixedly connected to the side surface of the limit clamp 5. A communicating air groove 8 is opened between the limit clamp 5 and the positioning slider 4. A support slide rod 9 is installed through the side surface of the limit clamp 5. An anti-slip pad 10 is fixedly connected to one end of the support slide rod 9. The anti-slip suction cups 7 are arranged horizontally and symmetrically arranged vertically. The anti-slip suction cups 7 are interconnected. One side of the anti-slip suction cup 7 is connected to the communicating air groove 8. The support slide rod 9 and the limit clamp 5 form a sliding connection. A spring is connected between the anti-slip pad 10 and the limit clamp 5. A rubber anti-slip strip is provided on the surface of the anti-slip pad 10. When the limit clamp 5 is close to the battery, the battery pushes the anti-slip pad 10, causing the support slide rod 9 to slide along the limit clamp 5, thereby driving the locking slider 11 to move.
[0024] The other end of the supporting slide rod 9 is fixed with a locking slider 11. The surface of the locking slider 11 is provided with an opening, and the inner wall of the opening of the locking slider 11 is fixed with a locking block 12. The linkage sealing mechanism includes a linkage slider 13. The linkage slider 13 is installed on the inner wall of the cavity of the limiting clamp 5. An adjusting tooth plate 14 is fixedly connected to the upper surface of the linkage slider 13. An adjusting gear 15 is provided on the inner wall of the cavity of the limiting clamp 5. A sealing baffle 16 is installed on the inner wall of the connecting air groove 8. The locking block 12 on the locking slider 11 disengages from the groove of the linkage slider 13, and the linkage slider 13 slides down along the cavity of the limiting clamp 5 under the action of its own spring.
[0025] The limiting clamp 5 is internally equipped with a linkage sealing mechanism. The workpiece pushes the anti-slip pad 10, support slide rod 9, and locking slider 11 to move, causing the locking block 12 to unlock and the linkage slider 13 to descend. This allows the spring to drive the linkage slider 13 and adjusting gear plate 14 to engage the adjusting gear 15, facilitating the rotation and opening of the sealing baffle 16. The linkage slider 13 and the limiting clamp 5 form a sliding connection, and a spring connects them. The linkage slider 13 passes through the opening of the locking slider 11. A groove is provided on the side surface of the linkage slider 13. 3 and locking block 12 form a locking connection. Adjusting tooth plate 14 and adjusting gear 15 form a meshing connection. The rotating shaft of adjusting gear 15 is fixedly connected to the rotating shaft of sealing baffle 16. The linkage slider 13 slides down and drives adjusting tooth plate 14 to move synchronously. Adjusting tooth plate 14 meshes with adjusting gear 15 and drives adjusting gear 15 to rotate. Since the rotating shaft of adjusting gear 15 is fixed to the rotating shaft of sealing baffle 16, sealing baffle 16 rotates to open the connecting air groove 8. The negative pressure generated by air pump 6 is transmitted to anti-slip suction cup 7 through connecting air groove 8. Anti-slip suction cup 7 adsorbs the battery to achieve stable fixation.
[0026] Working principle: When using this anti-pressure-damage PACK battery packaging clamp, the drive motor 2 is started, which drives the transmission screw 3 inside the support slider 1 to rotate. Because the two ends of the transmission screw 3 have reverse threads, the positioning slider 4, which is threaded to it, slides along the support slider 1, causing the limiting clamp 5 to approach the battery. The battery pushes the anti-slip pad 10, causing the support slider 9 to move the locking slider 11. The locking block 12 unlocks the linkage slider 13, which slides down under the action of the spring. The adjusting tooth plate 14 above it engages with the adjusting gear 15 and drives it to rotate. The rotating shaft of the adjusting gear 15 is fixed to the rotating shaft of the sealing baffle 16, so the sealing baffle 16 opens the connecting air groove 8. The negative pressure of the air pump 6 is transmitted to the anti-slip suction cup 7 through the connecting air groove 8. Finally, the anti-slip suction cup 7 adsorbs the battery, completing the clamping and fixing, increasing the overall practicality.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
