DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-4As shown, the battery cell precise positioning and lug shaping device includes a supporting assembly, a driving mechanism, a limiting mechanism and a sliding mechanism. The driving mechanism is vertically installed on the supporting assembly, and the driving mechanism is connected to the supporting assembly. The limiting mechanism is vertically installed on the supporting assembly, and the limiting assembly is connected to the driving mechanism for limiting the driving mechanism. The sliding mechanism is vertically installed on the supporting assembly, and the sliding mechanism is connected to the supporting assembly for driving the supporting assembly to move. The limiting mechanism includes a limiting sensor 301 and a limiting plate 302. The limiting plate 302 is vertically installed on the supporting assembly, and the limiting plate 302 is connected to the supporting assembly. The limiting sensor 301 is vertically installed on the limiting plate 302, and the limiting sensor 301 is connected to the limiting plate 302 for limiting the detected product.

[0020] Specifically, the limit sensor 301 and the limit plate 302 will limit the driving mechanism. When the driving mechanism moves to a preset limit position, the limit sensor 301 will send a signal to stop the driving mechanism from moving, thus avoiding over-position or collision and improving practicality.

[0021] The limiting mechanism includes a positioning block 303, a vertical plate 304 and a vacuum suction cup 305. The positioning block 303 is vertically installed on the driving mechanism, and the positioning block 303 is connected to the driving mechanism and is used to limit the position of the product. The two vertical plates 304 are vertically installed on the supporting assembly, and the vertical plates 304 are connected to the supporting assembly. The vacuum suction cup 305 is vertically installed between the two vertical plates 304, and the vacuum suction cup 305 is connected to the supporting assembly and is used to limit the position of the product.

[0022] Specifically, the positioning block 303 is vertically mounted on the driving mechanism to accurately limit the position of the battery cell. At the same time, the vacuum suction cup 305 between the two vertical plates 304 will generate negative pressure to tightly adsorb the battery cell on the workbench 102, further ensuring the stability of the battery cell during the shaping process and improving the practicality of the battery cell.

[0023] The limiting mechanism is provided with a sensing sheet 306 extending outwardly, and the sensing sheet 306 is vertically installed on the supporting assembly. The sensing sheet 306 is provided with a sensor 307 extending outwardly, and the sensor 307 is vertically installed on the supporting assembly. The sensor 307 is connected to the sensing sheet 306 and is used to limit the sliding mechanism.

[0024] Specifically, the cooperation between the sensor 307 and the sensor sheet 306 will monitor the position of the sliding mechanism in real time. When the sliding mechanism drives the workbench 102 to move, the sensor sheet 306 maintains an appropriate distance from the sensor 307. The sensor 307 does not detect the sensor sheet 306, and therefore does not generate a limit signal. At the same time, when the sensor sheet 306 moves to the point where the sensor 307 can detect the presence of the sensor sheet 306 and trigger a limit signal, a limit signal will be sent to the sliding mechanism, causing the sliding mechanism to slow down or stop the movement of the sliding mechanism, thereby achieving precise and reliable limit control of the sliding mechanism and improving practicality.

[0025] The driving mechanism includes a driving cylinder 201, which is vertically installed on the supporting assembly. One end of the driving cylinder 201 is provided with a clamping claw 202 connected thereto, and the clamping claw 202 is extended outwardly with a clamping plate 203, which is connected to the clamping claw 202 for grabbing the product.

[0026] Specifically, the driving cylinder 201 drives the opening and closing of the clamp 202. The clamp 203 connected to the clamp 202 is used to clamp the battery cell to ensure that the battery cell remains stable inside the clamp 203. By adjusting the stroke of the driving cylinder 201, the opening and closing degree of the clamp 202 can be controlled to adapt to battery cells of different sizes, thereby improving practicality.

[0027] The driving mechanism is extended outwardly to be provided with a rotating cylinder 205, and the rotating shaft 204 cylinder is vertically installed on the supporting assembly. One end of the rotating cylinder 205 is provided with a rotating shaft 204 connected thereto, which is used to drive the rotating shaft 204 to rotate.

[0028] Specifically, the rotating cylinder 205 drives the rotating shaft 204 to rotate, thereby driving the battery cell on the support plate 105 to rotate to one end of the vertical plate 304. At the same time, the vacuum suction cup 305 will suck the battery cell to prevent the battery cell from falling. During the rotation process, the driving cylinder 201 will adjust the position of the clamping claw 202 as needed to accurately shape the battery cell's tab, thereby improving practicality.

[0029] The sliding mechanism includes a driving motor 401, a screw rod 402, a linear guide rail 403 and a slider 404. The driving motor 401 is vertically installed on the supporting assembly, the screw rod 402 is installed on one end of the driving motor 401, the screw rod 402 is connected to the driving motor 401, and is used to drive the slider 404 to move. The linear guide rail 403 is vertically installed on the supporting assembly, the slider 404 is vertically installed on the linear guide rail 403, and the slider 404 is connected to the linear guide rail 403.

[0030] Specifically, the driving motor 401 drives the lead screw 402 to rotate, and then drives the slider 404 to move on the linear guide rail 403, so that the workbench 102 can be moved, which makes it easier to move the battery cell to a precise position and improves practicality.

[0031] The supporting assembly includes a base plate 101, a workbench 102 and a bracket 103. The bracket 103 is installed at one end of the base plate 101. The workbench 102 is vertically installed on the slider 404. The workbench 102 is connected to the slider 404. The limit plate 302 is located on the base plate 101. The vertical plate 304 is located on the workbench 102. The sensor 307 is located on the upper surface of the base plate 101. The sensor sheet 306 is located on one side of the workbench 102. The drive motor 401 is located on one side of the bracket 103. The linear guide rail 403 is located on the base plate 101.

[0032] Specifically, through the setting of the base plate 101, it is mainly used to support the entire equipment, thereby improving the stability of the entire equipment. Through the setting of the workbench 102, it is mainly used to further support the driving mechanism and the limiting mechanism. Through the setting of the bracket 103, it is mainly used to further support the mounting plate 104, thereby improving the stability of the mounting plate 104.

[0033] The supporting assembly includes a mounting plate 104, a supporting plate 105, a fixing plate 106 and a fixing block 107. The mounting plate 104 is vertically mounted on the bracket 103, and the mounting plate 104 is connected to the bracket 103 for supporting the driving cylinder 201. The supporting plate 105 is vertically mounted on the rotating shaft 204, and the supporting plate 105 is connected to the rotating shaft 204 for placing the product. The fixing plate 106 is vertically mounted on the workbench 102, and the fixing plate 106 is connected to the workbench 102 for supporting the driving assembly. The fixing block 107 is vertically mounted on the vacuum suction cup 305, and the fixing block 107 is connected to the vacuum suction cup 305 for supporting the battery cell. The driving cylinder 201 is located on the mounting plate 104, and the rotating shaft 204 cylinder is located at one end of the fixing plate 106.

[0034] Specifically, the installation plate 104 is mainly used to support the driving cylinder 201. When the battery cell is to be placed, the battery cell can be placed on the support plate 105. At the same time, in order to prevent the battery cell from falling, a positioning block 303 is provided between the two support plates 105 to limit the position of the battery cell. When the rotating shaft 204 and the rotating cylinder 205 are to be supported, the fixing plate 106 can be used to support the rotating shaft 204 and the rotating cylinder 205, thereby improving the stability of the rotating shaft 204 and the rotating cylinder 205.
