Detailed implementation manners

[0049] The technical solutions of the present application will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0050] The following combines Figures 1 - 8 , and describes the battery cell casing assembly device provided in the embodiments of the present application.

[0051] Referring to Figure 3 as shown, the battery cell casing assembly device provided by the embodiment of the present application includes a conveying table 100, a limiting tooling 200, a screw locking component 300, a detection component 400, and a removal component 500. The conveying table 100 is used to convey materials; the limiting tooling 200 is arranged on the conveying table 100. The limiting tooling 200 includes a profiling block, and the profiling block cooperates with the material in a concave-convex manner to place the material on the limiting tooling 200; the screw locking component 300 is arranged around the conveying table 100, and the screw locking component 300 assembles the material by installing screws on the material; the detection component 400 is arranged around the conveying table 100 and is used to detect whether the material is qualified; the removal component 500 is arranged around the conveying table 100 and is used to remove unqualified materials from the limiting tooling 200. Referring toFigure 1 , Figure 2 As shown, in some specific embodiments, the battery cell shell assembly equipment also includes a chassis 700 and a conveyor belt 800, a conveyor platform 100, a limit fixture 200, a screw locking assembly 300, a detection assembly 400 and a removal assembly 500 are respectively arranged in the chassis 700, and the conveyor belt 800 is arranged outside the chassis 700, and is used to convey the assembled finished product to the next process. It should be noted that the material refers to the shell cover and the cover plate, and the shell cover and the cover plate are assembled by screws. The assembled shell cover and the cover plate are conveyed to the next process via the conveyor belt 800. In some specific embodiments, the shape of the profiling block matches the shape of the material to achieve concave-convex matching, so that the material can be stably placed on the profiling block. In some specific embodiments, the conveying platform 100 is a turntable, and multiple limiting fixtures 200 are evenly distributed on the turntable around the central axis of the turntable. The turntable rotates around the central axis by a preset angle so that each limiting fixture 200 reaches the corresponding workstation; for example, four limiting fixtures 200 are arranged on the turntable, and the four rotating fixtures correspond to four workstations respectively, and the four workstations are respectively a detection station, a screw locking station, a removal station and a loading / unloading station. The central axis of the turntable is transmission-connected to the output shaft of the motor. Driven by the motor, the turntable rotates around the central axis, and the turntable rotates 90 degrees each time, so that each limiting fixture 200 rotates from the previous workstation to the next workstation. In this way, the materials on each limiting fixture 200 can be assembled and inspected in sequence.

[0052] By using the technical solution in the above embodiment, by setting a limit fixture 200 on the conveyor platform 100, the material can be moved to different workstations in sequence with the conveyor platform 100; by setting a locking screw assembly 300, a detection assembly 400 and a removal assembly 500 around the conveyor platform 100, the locking screw assembly 300 can automatically tighten the screws of the material to achieve assembly, and the detection assembly 400 can detect whether the material is qualified, such as whether the material is missing and whether the number of screws is correct, and the removal assembly 500 can remove the unqualified material from the conveyor platform 100, and the qualified material moves with the conveyor platform 100 to the finished product unloading place. The assembly equipment of the present application does not require too much human intervention, only manual loading and unloading is required, and the equipment has a fast beat; it can realize automatic error prevention, timely remove defective products, and improve product quality.

[0053] Reference Figure 4As shown, in some embodiments provided by the present application, the positioning tooling 200 includes a substrate 210 and positioning pins 220. A positioning hole is formed in the substrate 210, and the profiling block is arranged on the substrate 210; the positioning pins 220 are arranged on the conveying table 100, and the positioning pins 220 can pass through the positioning holes to limit the substrate 210 on the conveying table 100. Specifically, the number of positioning pins 220 corresponding to each positioning tooling 200 is multiple. For example, there are two positioning pins 220 corresponding to the positioning pins 220 of each positioning tooling 200. The substrate 210 is a rectangular plate, and a positioning hole is formed at each of the two diagonal positions of the substrate 210. The positions of the positioning pins 220 correspond to the positioning holes one by one. Thus, by adjusting the position of the substrate 210 and inserting it into the corresponding positioning pins 220, the substrate 210 can be quickly and accurately movably installed on the conveying table 100. Through the substrate 210 and the positioning pins 220, it can be ensured that the position of the substrate 210 on the conveying table 100 always remains consistent, ensuring that the material can fit well with the profiling block after feeding. In some specific embodiments, the positioning tooling 200 further includes a handle 230. The handle 230 is arranged on the substrate 210. By providing the handle 230, it is convenient to remove the substrate 210 from the conveying table 100 during tool change.

[0054] Refer to Figure 5As shown, in some embodiments provided by the present application, the detection component 400 includes a first detection mechanism 410 and a second detection mechanism 420. The first detection mechanism 410 is arranged on the upstream side of the screw-locking component 300 and is used to detect whether there is material on the profiling block; the second detection mechanism 420 is arranged on the downstream side of the screw-locking component 300 and is used to detect whether the assembled material is qualified. It should be noted that during manual feeding, there may be a situation where a certain positioning tooling 200 is short of material. Therefore, setting the first detection mechanism 410 on the upstream side of the screw-locking component 300 can timely detect the lack of material. In some specific embodiments, the first detection mechanism 410 includes a column 411, a moving seat 412, a detection rod 415, a high-position detection sensor 413, and a low-position detection sensor 414. The moving seat 412 is arranged on the column 411 and can move along the height direction of the column 411; the detection rod 415 is slidably matched with the moving seat 412, and the detection rod 415 moves along the height direction of the column 411 driven by the moving seat 412; the high-position detection sensor 413 and the low-position detection sensor 414 are respectively arranged on the moving seat 412 and are used to detect the position of the detection rod 415. The position of the high-position sensor is higher than that of the low-position sensor, and a proximity sensor can be used. Specifically, a linear slide is also installed on the column 411, and the moving seat 412 is installed on the linear slide. The moving seat 412 can move up and down driven by the linear slide, thereby driving the detection rod 415 to move up and down; in some specific embodiments, the detection rod 415 includes a sleeve 4151 and a rod body 4152. The sleeve 4151 is installed on the moving seat 412, and the rod body 4152 is slidably matched with the inner wall of the sleeve 4151. One end of the rod body 4152 away from the ground has an end cap 4153. Under the action of gravity, the end cap 4153 is blocked at the upper end of the sleeve 4151.

[0055] During detection, the detection rod 415 moves downward. When the detection rod 415 touches the material below and is blocked, it moves upward. At this time, the high-position sensor detects the detection rod 415 and outputs a signal to determine that "there is material on the positioning tooling 200"; when there is no material on the positioning tooling 200, the detection rod 415 will not touch the obstacle. At this time, the low-position sensor detects the detection rod 415 and outputs a signal to determine that "there is no material on the positioning tooling 200".

[0056] In some specific embodiments, the second detection mechanism 420 can be a vision camera. The vision camera is arranged on the downstream side of the screw-locking component 300 and is used to detect whether the assembled material is qualified, such as whether the number of screws is sufficient and whether the position of the screws is correct.

[0057] Refer to Figure 6As shown, in some embodiments provided by the present application, the screw locking assembly 300 includes an automatic screw locking machine 310. The automatic screw locking machine 310 is a machine that realizes the automatic conveying, tightening and other processes of screws through various electric and pneumatic components. Screws flow into a plastic pipe at the entrance of the automatic screw locking machine 310. The plastic pipe is made of nylon material with a wall thickness of 3 mm. The solenoid valve is opened to input high-pressure gas, and the screws are sequentially sent to the head position of the tightening gun. The vacuum bit at the head recognizes the screw cap and adsorbs the screw, and under the drive of the motor, the screw is tightened into the corresponding hole of the housing. The motor is signal-connected to the high-position sensor and the low-position sensor. When the motor receives the corresponding signal from the low-position sensor ("there is no material on the limit tooling 200"), the automatic screw locking machine 310 will not act and will not perform the screw locking operation on the material; when the motor receives the corresponding signal from the high-position sensor ("there is material on the limit tooling 200"), the automatic screw locking machine 310 will act within a preset time and perform the screw locking operation on the material.

[0058] Referring to Figure 7 As shown, the removal assembly 500 includes a base 510 and a moving jaw 520. The moving jaw 520 is arranged on the base 510 and can move along the height direction of the base 510 to separate non-conforming materials from the limit tooling 200, and can also move along the length direction of the base 510 to move the non-conforming materials to the material box 600. Specifically, the moving jaw 520 can move up and down driven by a cylinder. The cylinder is installed on a linear slide table, and the moving jaw 520 realizes left and right movement driven by the linear slide table. The cylinder is respectively signal-connected to the low-position sensor and the vision camera. After receiving the corresponding signal, the cylinder performs a downward movement and the moving jaw 520 grabs the non-conforming materials. In some specific embodiments, the removal assembly 500 further includes a first cross bar 530, a in-place detection sensor, a second cross bar 540 and a box-in detection sensor. The first cross bar 530 and the second cross bar 540 are respectively installed on the base 510. The first cross bar 530 faces the conveying table 100; the in-place detection sensor is arranged on the first cross bar 530 and is used to detect whether the non-conforming materials are in place; the second cross bar 540 faces the material box 600; the box-in detection sensor is arranged on the second cross bar 540 and is used to detect whether the non-conforming materials are moved to the material box 600. Specifically, the in-place detection sensor and the box-in detection sensor are proximity sensors. By installing the in-place detection sensor on the first cross bar 530, the in-place detection sensor can sense the material when the material reaches the corresponding station, so as to judge whether the tooling material is in place, so as to grab the non-conforming material after it is in place; by installing the box-in detection sensor on the second cross bar 540, the box-in detection sensor can sense whether the material is moved to the material box 600 after the material is transferred to the material box 600, so as to prevent the situation that the material is stuck at the entrance of the material box 600. Referring to Figure 8As shown, in some of these embodiments, the material box 600 includes an inlet section 610 and a drawer 620. Materials enter the drawer 620 through the inlet section 610, and the materials can be taken out just by pulling the drawer 620 open.

[0059] The working process of the battery cell case cover assembly device provided in the embodiments of the present application:

[0060] At the loading / unloading station, an operator loads materials (battery cell cases and covers) onto the profiling block. The conveying table 100 rotates 90 degrees, and the materials move to the first detection station. The detection rod 415 moves downward to detect whether there are materials on the profiling block.

[0061] If there are materials on the profiling block, the detection rod 415 touches the materials below and is blocked, so it moves upward. At this time, the high-position sensor detects the detection rod 415 and outputs a signal to determine that "there are materials on the positioning tooling 200". The conveying table 100 rotates 90 degrees, and the materials move to the screw-locking station. The screw-locking assembly 300 performs the screw-locking operation on the materials. The conveying table 100 rotates 90 degrees to the removal station again. During the rotation of the conveying table 100, the second detection mechanism 420 detects the materials after screw-locking. If the detection shows that they are unqualified, after the materials arrive, the removal mechanism grabs the unqualified materials and transfers them to the material box 600. If the detection shows that they are qualified, the assembled finished products will rotate 90 degrees with the conveying table 100 back to the loading / unloading station and are successfully unloaded.

[0062] If there are no materials on the profiling block, the detection rod 415 will not touch the obstruction. At this time, the low-position sensor detects the detection rod 415 and outputs a signal to determine that "there are no materials on the positioning tooling 200". And a signal is sent to the screw-locking assembly 300 and the removal assembly 500. The screw-locking assembly 300 will not perform the screw-locking operation on the materials. The conveying table 100 rotates 90 degrees to the removal station again, and the removal assembly 500 grabs the unqualified materials and transfers them to the material box 600.
