A movable plate 23 is slidably connected to the guide column 22. A cylinder 21 is connected above the movable plate 23. The cylinder 21 is fixed on the bracket 3, and the output end of the cylinder 21 passes through the bracket 3 and is connected to the movable plate 23. The bottom surface of the movable plate 23 is connected to the telescopic end of a vertical telescopic rod 31. The vertical telescopic rod 31 is installed on the ground. A battery discharge mechanism 5 is also provided on the mounting plate 1.

[0030] As an implementation method in this embodiment, the discharge mechanism 5 also includes a positioning block 55, which is a cylindrical shell with an inclined top surface and a hollow interior, and there are multiple groups of positioning blocks 55. The mounting plate 1 is also provided with a guide plate 51 corresponding to the position of the positioning block 55. The guide plate 51 is used to transport the battery to the positioning block 55. A weighing plate 54 is provided below the positioning block 55 to detect whether the battery is missing a cell. The weighing plates 54 are provided in multiple groups and are connected by a connecting rod 53. The connecting rod 53 is slidably connected to the mounting plate 1. The mounting plate 1 is also provided with a first electric telescopic rod 52 for driving the connecting rod 53 to move, so that when the battery is packaged, the weighing plate 54 can be moved out of the working area, and the battery will not be directly pressed on the weighing plate 54. A unloading mechanism 6 for the packaged battery is also provided below the weighing plate 54.

[0031] As an implementation method in this embodiment, the unloading mechanism 6 also includes a discharge plate 62 and a support plate 63. The support plate 63 is installed on the fixed end of the vertical telescopic rod 31. The discharge plate 62 is arranged below the weighing plate 54. The side wall of the through groove of the mounting plate 1 and the support plate 63 are provided with a slide groove. The discharge plate 62 is installed in the slide groove on the support plate 63 through the second electric telescopic rod 61. The discharge plate 62 is connected to the telescopic end of the second electric telescopic rod 61. The support plate 63 is clamped with the mounting plate 1, and one end of the discharge plate 62 is located at the mounting plate 1. The other end is located in the slide groove of the support plate 63, so that when the equipment compresses and packages the battery, the discharge plate 62 plays a supporting role. At the same time, under the action of the second electric telescopic rod 61, the discharge plate 62 slides between the two slide grooves on the mounting plate 1 and the support plate 63. The cross-section of the discharge plate 62 is trapezoidal, and the connection between the second electric telescopic rod 61 and the discharge plate 62 is not directly below the positioning block 55, so as to avoid interference with the battery during discharge. The discharge plate 62 can control the discharge direction of the battery under the action of the second electric telescopic rod 61.

[0032] As an implementation method in this embodiment, a baffle 41 is provided in the material receiving box 4 arranged below the discharge plate 62 to divide the material receiving box 4 into an unpackaged area and a packaged area.

A retrieval port for quickly removing unpackaged batteries is also provided on the side wall of the unpackaged area of ​​the material receiving box 4.

[0033] The working principle of this utility model is as follows: when in use, the equipment is first connected to the power supply, and the opening and closing of the electrical components of the equipment are controlled by adopting an external PLC control unit. The guide plate 51 in the discharge mechanism 5 is first connected to the feeding vibration plate, and the batteries to be processed are transported to the guide plate 51 of the discharge mechanism 5. The batteries are moved to the positioning block 55 through the guide plate 51, and the weighing plate 54 under the positioning block 55 weighs the batteries, detects and records the positions of the batteries with missing cells through the PLC external control unit, and then the first electric telescopic rod 52 drives the weighing plate 54 to move through the connecting rod 53, so that it leaves the bottom of the positioning block 55, and makes the batteries fall onto the discharge plate 62. According to the recorded position of the batteries with missing cells, the PLC external control unit controls its corresponding second electric telescopic rod 61 to push out The material plate 62 slides the discharge plate 62 into the slide groove on the mounting plate 1, so that the battery with missing cells passes through the inclined surface on the discharge plate 62 close to the support plate 63 and slides onto the dividing plate 42 of the receiving box 4, and then falls into the unpackaged area. After that, the battery cap is placed on the top of the battery, and the cylinder 21 in the stamping mechanism 2 pushes the movable plate 23 through the stamping mechanism 2 on the bracket 3, so that the movable plate 23 slides downward on the guide column 22, and the movable plate 23 seals the cap and the battery downward. After the packaging is completed, the second electric telescopic rod 61 pulls the discharge plate 62 longitudinally, so that the processed battery passes through the inclined surface on the discharge plate 62 close to the mounting plate 1 side and slides onto the dividing plate 42 of the receiving box 4, and then falls into the finished product area. After that, the equipment is reset and the next packaging is repeated.
