DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be arbitrarily combined with each other.

[0024] See also Figures 1 to 4The embodiment of the utility model is a battery cell clamping device for square aluminum shell batteries, comprising a first adjusting member, a first lifting member, two upper clamping plates 11, two connecting pads 19 respectively connected to the two upper clamping plates 11, two pressure detecting members 22 respectively arranged on two side surfaces close to each other on the two connecting pads 19, a plurality of hot melt adhesive strips 20 respectively arranged on the two connecting pads 19, a plurality of heating members 21 for respectively heating the plurality of hot melt adhesive strips 20, and a controller 23 for respectively controlling the first adjusting member, the first lifting member and the heating member 21; the first lifting member is used to drive the first adjusting member to move up and down; the first lifting member drives the first adjusting member to move downward to a first preset height In order to clamp the battery cell, the controller 23 is used to control the first adjusting member to drive the two upper clamps 11 to move closer, so that the two connecting pads 19 are respectively in contact with the two side surfaces of the battery cell that are away from each other; the pressure detecting member 22 is used to detect the real-time pressure exerted on the connecting pad 19; the controller 23 is used to control the first adjusting member to stop when the real-time pressure is equal to the preset pressure, and control the heating member 21 to heat the hot-melt adhesive strip 20 for a first preset time, so that the hot-melt adhesive strip 20 softens and is bonded to the battery cell after cooling and fixing. The controller 23 is used to control the heating member 21 to heat the hot-melt adhesive strip 20 for a second preset time when the clamped battery cell is placed on the work surface, so that the hot-melt adhesive strip 20 softens and is separated from the battery cell.

[0025] Here, the battery cell of the square aluminum shell battery can be placed vertically in the initial position, the first lifting member can be set vertically, and the connecting pad 19 can be set vertically; the battery cell is initially placed on the initial table, and the controller 23 controls the first lifting member so that the first lifting member drives the first adjusting member to move downward to a first preset height, so that the two connecting pads 19 move to a position that matches the height of the battery cell placed on the initial table; the controller 23 controls the first adjusting member so that the first adjusting member drives the two upper clamps 11 to move closer, so that the two upper clamps 11 drive the two connecting pads 19 to move closer, and the two connecting pads 19 respectively abut against the battery cell. The two sides of the core are away from each other; the pressure detection part 22 detects the real-time pressure on the connecting pad 19 squeezed by the battery cell. When the real-time pressure is equal to the preset pressure, it indicates that the clamping force applied by the two upper clamping plates 11 on the battery cell is most appropriate, and the clamping force will not be too small or too large. If the first adjustment member continues to drive the two upper clamping plates 11 to move closer, the two connecting pads 19 continue to move closer, and the real-time pressure applied by the battery cell to the connecting pad 19 will be greater than the preset pressure, and the clamping force applied by the two upper clamping plates 11 on the battery cell will be too large, which may easily cause damage to the battery cell. Therefore, when the real-time pressure is equal to the preset pressure, the controller 23 controls the first The adjusting member stops; then the controller 23 controls the heating member 21 to heat the hot melt adhesive strip 20 for a first preset time, so that the hot melt adhesive strip 20 softens and sticks to the battery cell. After heating for the first preset time, the controller 23 controls the heating member 21 to stop, so that the heating member 21 no longer heats the hot melt adhesive strip 20, and the hot melt adhesive strip 20 cools and solidifies.

After the first adjusting member 11 descends a certain height, the first adjusting member controls the upper clamping plate 11 to move toward the battery cell, thereby clamping the battery cell.

The lower piston rod 12 returns to its initial position. The electric slide rail 4 drives the sliding frame 6 and the upper clamping plate 11 to move downward through the slide 5. The downward moving upper clamping plate 11 will drive the battery cells to fall onto the work surface.

[0048] 5. The controller 23 starts the heating element 21, which heats and softens the hot-melt adhesive strip 20. The controller 23 starts the first drive motor 25. The first drive motor 25 drives the worm gear and the support rod 7 to rotate in opposite directions through the worm 10. The reverse-rotating support rod 7 drives the upper clamping plate 11 to move away from the battery cell through the sliding nut 8, and the upper clamping plate 11 is separated from the battery cell. At the same time, the controller 23 starts the electric push rod 16, which pushes the scraper 17 to move outward. The scraper 17 moving outward is close to the battery cell. The electric slide rail 4 drives the sliding frame 6 and the upper clamping plate 11 to move upward through the slide 5. The upper clamping plate 11 drives the scraper 17 to rise along the outer wall of the battery cell through the lower piston rod 12. The scraper 17 sliding upward will scrape off the glue marks of the hot-melt adhesive strip 20 remaining on the battery cell.

[0049] Specifically, the present application has the following advantages: 1. The first drive motor 25 is started by the controller 23, and the first drive motor 25 drives the support rod 7 to rotate. The rotating support rod 7 drives the two sets of upper clamps 11 to clamp the battery cells through the sliding nut 8. The pressure sensor in the connecting pad 19 detects the pressure data. The controller 23 controls the first drive motor 25 to stop running according to the signal input by the pressure sensor, so that the upper clamp 11 is no longer close to the battery cells. The heating element 21 heats and softens the hot melt adhesive strip 20. The softened hot melt adhesive strip 20 will stick to the battery cells. The heating element 21 is then turned off. The hot melt adhesive strip 20 cools and solidifies. The cooled and solidified hot melt adhesive strip 20 will stick the battery cells to the upper clamp 11. The electric slide rail 4 slides The frame 6 drives the upper clamping plate 11 to move upward, and the rising upper clamping plate 11 will lift the battery cell. The air pump 18 sends air into the upper clamping plate 11, and the incoming air will push the lower piston rod 12 to move downward, and the lower piston rod 12 drives the supporting plate 15 to descend to the bottom of the battery cell. The second drive motor 14 drives the supporting plate 15 to rotate, and the supporting plate 15 is rotated to the bottom of the battery cell. The air pump 18 then extracts the air in the upper clamping plate 11, and the return spring 13 drives the lower piston rod 12 and the supporting plate 15 to move upward, and the rising supporting plate 15 will press against the bottom of the battery cell. The supporting plate 15 will support the battery cell. During the transportation process, the battery cell is not easy to fall, and the pressure when clamping the battery cell is controllable, the battery cell is not easily damaged, and the safety is higher.

[0050] 2. The electric push rod 16 pushes the scraper 17 outward. The outward-moving scraper 17 will be close to the battery cell. The upper clamping plate 11 drives the scraper 17 to rise along the outer wall of the battery cell through the lower piston rod 12. The upward-sliding scraper 17 will scrape off the glue marks of the hot melt adhesive strip 20 remaining on the battery cell.
