[0017] 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.

[0018] Example: Please refer to Figures 1-7 A solid-state soft-pack battery extrusion device includes: a base 1, on which a housing 11 is mounted; a feeding mechanism 2, mounted on the base 1, for conveying the battery to the extrusion station; the feeding mechanism 2 includes a conveying component, on which an adjusting component for adjusting the battery height is mounted, and a limiting component for limiting the battery is mounted on the upper end of the adjusting component; the limiting component includes a feeding fixing seat 26 mounted on the upper end of the adjusting component, the feeding fixing seat 26 having a plurality of threaded holes distributed thereon, a limiting baffle 261 provided on the upper left side of the feeding fixing seat 26, and a limiting bracket 262 provided on the upper right side of the feeding fixing seat 26, the bolts on the limiting baffle 261 and the limiting bracket 262 being threadedly connected to the corresponding threaded holes; a pair of side pressing mechanisms 3, mounted on the upper end of the base 1, for extruding the battery from the left and right sides; and a pressing plate mechanism 4, mounted on the side pressing component, for extruding the battery from the top.

[0019] The working principle of this utility model is as follows: In this embodiment, by adjusting the positions of the limiting baffle 261 and the limiting card seat 262, it is convenient to position batteries of different sizes. After positioning is completed, the battery is transported to the pressurization position by the conveying component. The side pressing mechanism moves closer to each other from both sides to squeeze the battery. The pressure plate mechanism moves downward to squeeze the battery from above. This can realize multi-angle squeezing of batteries of different sizes, which can better meet the needs of use.

[0020] As a further embodiment, the conveying assembly includes a pair of feeding brackets 21 mounted on the base 1. Each feeding bracket 21 is equipped with a feeding slide rail 22. A feeding slide block 23 is slidably mounted on the feeding slide rail 22. An adjustment component is mounted on the feeding slide block 23. Each feeding bracket 21 is also equipped with a feeding rodless cylinder 20. The moving end of the feeding rodless cylinder 20 is fixedly connected to the feeding slide block 23. The working principle of the conveying component is as follows: the feeding rodless cylinder 20 drives the feeding slide 23 to move backward, which in turn drives the battery to move backward and move it to the extrusion station for extrusion processing.

[0021] The adjustment components are provided in pairs, and the pair of adjustment components are distributed on the front and rear sides of the feeding slide 23. The adjustment components include a feeding mounting plate 24 installed on the feeding slide 23. An adjustment electric cylinder 27 is installed at the lower end of the feeding mounting plate 24. The telescopic end of the adjustment electric cylinder 27 passes through the feeding mounting plate 24 and is fixed to a feeding adjustment plate 25. A feeding guide rod is also slidably inserted on the feeding mounting plate 24. The upper end of the feeding guide rod is fixedly connected to the lower end of the feeding adjustment plate 25.

[0022] During adjustment, the electric cylinder 27 is adjusted to move the feeding adjustment plate 25 up and down, thereby adjusting the battery height and facilitating subsequent extrusion work.

[0023] Between the adjustment components is an auxiliary bracket 28 installed on the feeding slide 23. An auxiliary pad 281 is installed on the auxiliary bracket 28. An auxiliary support plate 282 is installed on the upper end of the auxiliary pad 281. The upper end of the auxiliary support plate 282 is flush with the upper surface of the feeding fixed seat 26.

[0024] The height of the auxiliary support plate 282 can be adjusted by changing the number of auxiliary pads 281, so that its upper surface is flush with the upper surface of the feeding fixing seat 26, thereby better supporting the battery.

[0025] As a further embodiment, the feeding adjustment plate 25 is also equipped with a fine-tuning component, which includes a fine-tuning bracket 29 installed on the feeding adjustment plate 25. A fine-tuning electric cylinder 291 is installed on the fine-tuning bracket 29, and the telescopic end of the fine-tuning electric cylinder 291 passes through the fine-tuning bracket 29 and is equipped with a fine-tuning push plate 292.

[0026] The working principle of the fine-tuning component is as follows: by extending the fine-tuning electric cylinder 291, the fine-tuning push plate 292 is moved, thereby pushing the battery to move backward, thus realizing the fine-tuning of the battery position, which facilitates the subsequent extrusion work.

[0027] As a further embodiment, the side-pressing mechanism 3 includes a side-pressing bracket 31 mounted on the base 1. Positioning electric cylinders 32 are installed on both the front and rear sides of the side-pressing bracket 31. The telescopic end of the positioning electric cylinder 32 passes through the side-pressing bracket 31 and is fixed with a positioning push plate 33. A positioning clamping plate 34 is also installed on the positioning push plate 33. A side-pressing port is opened in the middle of the positioning push plate 33. A side-pressing electric cylinder 35 is also installed in the middle of the side-pressing bracket 31 corresponding to the side-pressing port. The telescopic end of the side-pressing electric cylinder 35 passes through the side-pressing bracket 31 and is fixed with a side-pressing push plate 36. A side-pressing clamping plate 37 is also installed on the side-pressing push plate 36. In this embodiment, side-pressing guide rods 38 are also installed on the side-pressing brackets 31 of the side-pressing mechanism 3 on both the left and right sides. The positioning push plate 33 is slidably fitted onto the side-pressing guide rods 38. In this embodiment, the connecting assembly 30 includes a connecting sleeve 301 fixed on the positioning push plate 33 (or the side pressure push plate 36). A connecting boss 303 is slidably inserted into the connecting sleeve. The other end of the connecting boss 303 is fixedly connected to the telescopic end of the positioning electric cylinder (or the side pressure electric cylinder 35). Pressure sensors 302 are installed on the positioning push plate 33 (side pressure push plate 36) at positions corresponding to the connecting sleeve 301. To facilitate monitoring of battery compression deformation, displacement sensors 39 are installed on the side pressure bracket at positions corresponding to the positioning push plate 33 and the side pressure push plate 36. By setting the pressure sensors 302 in conjunction with the displacement sensors 39, it is convenient to monitor the pressure magnitude and the battery compression deformation.

[0028] The working principle of the side pressing mechanism 3 is as follows: the left positioning electric cylinder 32 extends and pushes the positioning push plate 33 to move towards the middle, so that the left positioning clamp 34 abuts against the limiting baffle 261. Then, by pushing the right positioning push plate 33 towards the middle, the right positioning clamp 34 can be brought closer to the battery, and the battery can be positioned in conjunction with the limiting baffle 261. Subsequently, the right side pressing electric cylinder 35 extends and pushes the side pressing push plate 36 to move towards the middle position, so that the side pressing clamp 37 passes through the side pressing port to apply pressure to the battery, and the battery can be squeezed on both sides in conjunction with the limiting baffle 261. When the battery is positioned on both sides of the loading fixing seat 26 by the limiting card seat 262, the positioning electric cylinder pushes the positioning clamps 34 on both sides to approach the battery to complete the positioning work. The side pressure electric cylinders 35 on both sides extend at the same time, pushing the side pressure push plates 36 on both sides to approach each other, so that the battery can be squeezed from both sides at the same time, which can better meet different processing needs.

[0029] As a further embodiment, the pressure plate mechanism 4 includes a top pressure bracket 41 installed on the upper end of the side pressure bracket 31. Lifting electric cylinders 42 are installed on both the left and right sides of the top pressure bracket 41. The telescopic ends of the lifting electric cylinders 42 pass through the top pressure bracket 41 and are fixed to a lifting seat plate 43. A top pressure mounting frame 44 is installed in the middle of the lifting seat plate 43. A top pressure electric cylinder 45 is installed on the upper end of the top pressure mounting frame 44. The telescopic ends of the top pressure electric cylinder 45 pass through the top pressure mounting frame 44 and are fixed to a top pressure lifting seat 46. Top pressure guide rods 47 are installed at the four corners of the lower end of the top pressure lifting seat 46. The lower ends of the top pressure guide rods 47 pass through the lifting seat plate 43 and are fixed to a top pressure plate 48.

[0030] The working principle of the pressure plate mechanism 4 is as follows: In specific use, the lifting electric cylinder 42 first drives the lifting seat plate 43 to move and adjust the height of the lifting seat plate 43. After the adjustment is completed, the top pressure electric cylinder 45 extends and pushes the top pressure lifting seat 46 to move down. The top pressure guide rod 47 pushes the top pressure plate 48 to move down, which can squeeze the upper end of the battery. By setting the pressure plate mechanism 4, the squeezing on both sides can effectively prevent the middle position of the battery from arching, reducing the damage to the battery caused by squeezing.
