[0027] 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.

[0028] Example: Reference Figure 1-8 The shown is a nickel-metal hydride battery core pressing device, which includes a frame 1, a feeding conveyor belt 2, a support platform 4, a discharging conveyor belt 3, a feeding rack 5, and a gantry 6.

[0029] The frame 1 is rotatably connected to the conveyor rollers 11. There are four sets of conveyor rollers 11. The two sets of conveyor rollers 11 at the rear are fitted with the feed conveyor belt 2, and the two sets of conveyor rollers 11 at the front are fitted with the discharge conveyor belt 3. The frame 1 is equipped with a conveyor motor 10 to drive the conveyor rollers 11. The conveyor rollers 11 are driven by synchronous belt transmission. The conveyor motor 10 drives the conveyor rollers 11 to rotate, thereby driving the feed conveyor belt 2 and the discharge conveyor belt 3 to operate.

[0030] The feeding conveyor belt 2, the support platform 4, and the discharging conveyor belt 3 are arranged adjacent to each other from back to front and their top surfaces are flush. The support platform 4 is located between the feeding conveyor belt 2 and the discharging conveyor belt 3. The feeding conveyor belt 2 and the discharging conveyor belt 3 operate in the same direction and synchronously to ensure that the battery cells can be smoothly transferred between the three.

[0031] The feeding rack 5 is located above the support platform 4, and its front and rear ends extend above the infeed conveyor belt 2 and the discharge conveyor belt 3. Vertical plates 50 are symmetrically arranged at the front and rear ends of the feeding rack 5. Rotating shafts 52 are rotatably connected between the corresponding vertical plates 50 on the left and right sides. Sprockets 53 are symmetrically arranged at the left and right ends of the rotating shafts 52. Chains 54 are fitted onto the two sets of sprockets 53 corresponding to the front and rear ends. Feeding rods 55 are connected between the two sets of chains 54. Multiple sets of feeding rods 55 are evenly arranged. The rotating shaft 52 is driven by a feeding motor 51, which is a servo motor. The feeding motor 51 drives the rotating shaft 52 to rotate, which in turn drives the sprockets 53 to rotate. The sprockets 53 then drive the chains 54 to move, thus causing the feeding rods 55 to move along with the chains 54, thereby pushing the battery cells.

[0032] The gantry 6 is located above the feeding rack 5. A telescopic cylinder 60 is mounted on the top of the gantry 6, with its telescopic end pointing downwards. A core-pressing frame 7 is located at the bottom of the telescopic end of the cylinder 60. The upper part of the chain 54 passes through the core-pressing frame 7, and a pressing block 70 is located at the bottom of the core-pressing frame 7, corresponding to the position of the support platform 4. When the battery cell is pushed onto the support platform 4, the telescopic cylinder 60 extends, causing the core-pressing frame 7 and the pressing block 70 to move downwards, performing a core-pressing operation on the battery cell. After pressing is completed, the telescopic cylinder 60 retracts, causing the core-pressing frame 7 and the pressing block 70 to return to their original position.

[0033] Guide bars 61 are symmetrically arranged on the left and right inner side walls of the gantry 6, and guide blocks 71 are symmetrically arranged on the left and right sides of the core pressing frame 7. The guide blocks 71 work with the guide bars 61 to guide the movement of the core pressing frame 7, making the up and down movement of the core pressing frame 7 more stable.

[0034] The frame 1 is symmetrically provided with guide frames 12, which are located above the feeding conveyor belt 2. The rear of the two sets of guide frames 12 extends outward, and the interval between the two sets of guide frames 12 corresponds to the position of the feeding rod 55. The guide frames 12 guide the battery cells entering the feeding conveyor belt 2, ensuring that they can move accurately towards the support platform 4.

[0035] The feeding rack 5 is equipped with a guide frame 56, and the guide frame 56 is symmetrically equipped with guide plates 57. The guide plates 57 are located between two sets of chains 54. The rear parts of the two sets of guide plates 57 extend outward, and the rear parts of the guide plates 57 are adapted to the front parts of the feeding rack 12. The guide plates 57 further guide the battery core to accurately enter the pressing position.

[0036] Positioning blocks 72 are symmetrically arranged on the left and right sides of the pressing block 70. The positioning blocks 72 correspond to the rear position of the guide plate 57. Positioning grooves 40 are symmetrically arranged on the support platform 4. The positioning grooves 40 are adapted to the positioning blocks 72. During the pressing process, the positioning blocks 72 are inserted into the positioning grooves 40 to accurately position the battery core and ensure that the battery core is subjected to uniform force.

[0037] The working principle of this utility model is as follows: During use, the battery cell is placed on the feeding conveyor belt 2 at the rear of the frame 1. The conveyor motor 10 drives the conveyor roller 11 to rotate, causing the feeding conveyor belt 2 to rotate and convey the battery cell forward. Guided by the guide frame 12, the battery cell moves towards the middle of the feeding conveyor belt 2 and accurately towards the support platform 4. Simultaneously, the feeding motor 51 on the vertical plate 50 drives the rotating shaft 52 to rotate, which in turn drives the feeding rod 55 through the sprocket 53 and chain 54. The feeding rod 55 pushes the battery cell conveyed on the feeding conveyor belt 2 along the feeding frame 5 to the support platform 4. During this process, the guide frame 56 and guide plate 57 further guide the battery cell, causing it to move towards the lower part of the pressing block 70. When the battery core reaches the pressing position on the support platform 4, the telescopic cylinder 60 on the gantry 6 extends, driving the pressing frame 7 and the pressing block 70 to move downwards. The guide block 71 and the guide bar 61 cooperate to ensure that the pressing frame 7 falls stably. When the positioning blocks 72 on both sides of the pressing block 70 fall, they position the side of the battery core so that the battery core is directly below the pressing block 70. Then, the positioning groove 40 on the support platform 4 engages with the positioning block 72 and inserts, while the pressing block 70 compacts the battery core. After pressing is completed, the telescopic cylinder 60 shortens, driving the pressing frame 7 and the pressing block 70 to reset upwards. Subsequently, the feeding rod 55 continues to move, pushing the pressed battery core onto the discharge conveyor belt 3, which then transports it to the next process.
