[0004] This automatic battery cell sealing device, while able to slide downwards via a guide rod and seal the battery cell through a heating plate during the sealing process, is prone to developing bulges and air bubbles on the sealing film surface, leading to a decrease in sealing quality. Therefore, the device needs to be improved. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic cell sealing device, comprising a base plate, wherein a flattening mechanism is fixedly connected to the front and rear ends of the top of the base plate, and a sealing mechanism is fixedly connected to the right end of the top of the base plate; The pushing mechanism includes a driving component and a clamping component, wherein the clamping component is disposed on the surface of the driving component; The drive assembly includes two sets of first electric actuators, which are respectively fixedly connected to the front and rear ends of the top of the base plate.

A motor is fixedly connected to the left end of the slide block, and a lead screw is fixedly connected to the right end of the motor. A cross-threaded block is threaded onto the surface of the lead screw, and there are two cross-threaded blocks. A gantry frame is fixedly connected between the two cross-threaded blocks, and a pressure roller is rotatably connected inside the gantry frame.

[0007] Preferably, a guide groove is formed inside the slide block, the surface of the cross-threaded block is slidably connected to the inside of the guide groove, and the right end of the lead screw is rotatably connected to the inside of the guide groove, so as to facilitate the sliding of the cross-threaded block under the limiting position inside the guide groove.

[0008] Preferably, the clamping assembly includes a support plate, there are two support plates, the two support plates are respectively fixedly connected to the top of the base plate, an adjusting screw is threadedly connected to the middle of the inside of the support plate, a clamping bar is fixedly connected to one end of the adjusting screw, a stop block is fixedly connected to the top left end of the base plate, and limit strips are fixedly connected to both ends of the surface of the clamping bar.

[0009] Preferably, the support plate has limiting holes at its left and right ends, and the surface of the limiting strip is slidably connected to the limiting hole, so that the limiting strip can move under the limitation of the limiting hole.

[0010] Preferably, the sealing mechanism includes an L-shaped plate, which is fixedly connected to the top right end of the base plate.

[0013] Compared with the prior art, the present invention provides an automatic battery cell sealing device, which has the following advantages: This automatic battery cell sealing device, through a set flattening mechanism, rotates the adjusting screw to drive the clamping strip to move under the limiting support of the support plate, thereby clamping and fixing the workpiece. At this time, the start motor drives the lead screw to rotate under the support inside the slide block and drives the cross thread block to move, thereby driving the gantry frame and pressure roller to move. The pressure roller lowers the sealing film and flattens it by adhering to the surface of the workpiece. This ensures the flatness of the sealing film when sealing the workpiece and effectively avoids the phenomenon of bulging and air bubbles on the surface of the sealing film during sealing, thus ensuring the sealing quality of the battery cell.

[0014] This automatic cell sealing device, through a sealing mechanism, uses a second electric push rod to drive the support frame downwards, which in turn drives the crossbar and support block downwards. Then, the support block drives the heating plate downwards to the upper corner of the right end of the cell. The support block continues to move downwards, allowing the heating plate to rotate under the support of the crossbar until it is perpendicular to and fits against the right end of the cell. This fixes the sealing film on the right end of the cell onto the cell, thus achieving the sealing effect. Attached Figure Description

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] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] This utility model provides the following technical solution: Example 1: Combining Figures 2 to 7 An automatic sealing device for battery cells includes a base plate 1, with a flattening mechanism 2 fixedly connected to the front and rear ends of the top of the base plate 1, and a sealing mechanism 3 fixedly connected to the right end of the top of the base plate 1. The flattening mechanism 2 includes a driving component 21 and a clamping component 22, with the clamping component 22 disposed on the surface of the driving component 21; The drive assembly 21 includes two sets of first electric actuators 211, which are fixedly connected to the front and rear ends of the top of the base plate 1, respectively. An L-shaped strip 212 is fixedly connected to the top of each first electric actuator 211. A slide block 213 is fixedly connected to the surface of the L-shaped strip 212. A motor 214 is fixedly connected to the left end of the slide block 213, and a lead screw 215 is fixedly connected to the right end of the motor 214. A cross-threaded block 216 is threaded onto the surface of the lead screw 215. There are two cross-threaded blocks 216, and a portal frame 217 is fixedly connected between the two cross-threaded blocks 216. The 17 is internally rotatably connected to a pressure roller 218. A guide groove is opened inside the slide block 213. The surface of the cross threaded block 216 is slidably connected to the inside of the guide groove. The right end of the screw 215 is rotatably connected to the inside of the guide groove. The clamping assembly 22 includes a support plate 221. There are two support plates 221. The two support plates 221 are respectively fixedly connected to the top of the base plate 1. An adjusting screw 224 is threadedly connected to the middle of the support plate 221. A clamping bar 223 is fixedly connected to one end of the adjusting screw 224. A stop block 225 is fixedly connected to the top left end of the base plate 1. Limiting bars 222 are fixedly connected to both ends of the surface of the clamping bar 223.

[0020] Furthermore, limiting holes are respectively opened at the left and right ends of the support plate 221. The surface of the limiting strip 222 is slidably connected to the limiting hole. Rotating the adjusting screw 224 drives the clamping strip 223 to move under the limiting support of the support plate 221 using the limiting strip 222, thereby clamping and fixing the workpiece. At this time, the starting motor 214 drives the lead screw 215 to rotate under the support inside the slide block 213 and drives the cross thread block 216 to move, thereby driving the gantry frame 217 and the pressure roller 218 to move and allowing the pressure roller 218 to lower the sealing film and flatten it by adhering to the surface of the workpiece. This ensures the flatness of the sealing film when sealing the workpiece and effectively avoids the phenomenon of bulging and air bubbles on the surface of the sealing film during sealing, thereby ensuring the sealing quality of the battery cell.

[0021] Example 2: See Figure 1-7 Furthermore, based on Embodiment 1, the sealing mechanism 3 further includes an L-shaped plate 31, which is fixedly connected to the top right end of the base plate 1. A second electric push rod 32 is fixedly connected inside the top end of the L-shaped plate 31, and a support crossbar 33 is fixedly connected to the bottom end of the second electric push rod 32. Springs 35 are fixedly connected to both ends of the support crossbar 33, and a support block 36 is fixedly connected to one end of the spring 35. A heating plate 37 is fixedly connected to the bottom end of the support block 36, and a crossbar 34 is fixedly connected inside the support block 36. Through holes are opened at both ends of the support crossbar 33, and the surface of the crossbar 34 is rotatably connected to the through holes.

[0022] Furthermore, a through hole is opened inside the top of the L-shaped plate 31, and the surface of the second electric push rod 32 penetrates through the through hole inside the top of the L-shaped plate 31. The second electric push rod 32 drives the support crossbar 33 downward, which in turn drives the crossbar 34 and the support block 36 to move downward. Then, the support block 36 drives the heating plate 37 downward to the upper corner position of the right end of the battery cell. The support block 36 continues to move downward, so that the heating plate 37 rotates under the support of the crossbar 34 until it is perpendicular to and fits against the right end of the battery cell. This can fix the sealing film on the right end of the battery cell to the battery cell and play a sealing role.

[0023] In actual operation, when this device is used, an opening slot is opened inside the right end of the base plate 1. When sealing the battery cell, the battery cell workpiece is clamped first. Before clamping, the sealing film is sealed and fixed to the left end of the workpiece. At this time, the workpiece is placed on the base plate 1, and one end of the sealing film is aligned with one end of the abutment block 225. Then, the adjusting screw 224 is rotated to drive the clamping bar 223 to move under the limiting support of the support plate 221 using the limiting bar 222, thereby clamping and fixing the workpiece. At this time, the motor 214 is started to drive the lead screw 215 to rotate under the support inside the slide block 213 and drive the cross thread block 216 to move, thereby driving the gantry frame 217 and the pressure roller 218 to move and allowing the pressure roller 218 to lower the sealing film and flatten it by adhering to the surface of the workpiece. This ensures the flatness of the sealing film when sealing the workpiece, thereby ensuring the sealing quality of the battery cell. During the sealing process, the heating plate 37 is heated to a suitable and stable temperature, causing the second electric push rod 32 to drive the support crossbar 33 downward, which in turn drives the crossbar 34 and support block 36 to move downward. Then, the support block 36 drives the heating plate 37 downward to the upper corner of the right end of the battery cell. The support block 36 continues to move downward, so that the heating plate 37 rotates under the support of the crossbar 34 until it is perpendicular to and fits against the right end of the battery cell. This fixes the sealing film on the right end of the battery cell to the battery cell, thus achieving the sealing effect.
