[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0044] like Figures 1 to 4 As shown, the explosion-proof valve feeding device of this embodiment includes a first turntable assembly 1, the first turntable assembly 1 includes a first turntable 11 and a plurality of first carriers 12, the explosion-proof valve can be placed on the first carrier 12, the plurality of first carriers 12 are evenly distributed on the first turntable 11, and a plurality of stations are evenly distributed around the first turntable 11, each station corresponds to at least one first carrier 12, and the plurality of stations at least include a first loading station, a first identification station, a flip station, a shaping station, a second identification station and a discharging station arranged in sequence, and the first turntable 11 drives the first carrier 12 and the explosion-proof valve to pass through all the stations in sequence, and then transfers the explosion-proof valve to the next process at the discharging station. In this embodiment, eight first carriers 12 are arranged on the first turntable 11, that is, the first turntable 11 is arranged with eight transfer positions, wherein the flip station is arranged corresponding to two transfer positions, and the remaining stations are arranged corresponding to one transfer position, and an empty position is arranged between the loading station and the discharging station, and the empty position is arranged corresponding to one transfer position.

[0045] The explosion-proof valve loading device includes a first loading assembly 2, which is arranged at a first loading station and is used to place the explosion-proof valve on the first carrier 12. In this embodiment, the first loading assembly 2 includes a feeding mechanism 21 and a first picking mechanism, the feeding mechanism 21 is used to store a plurality of explosion-proof valves, and the first picking mechanism is used to move the explosion-proof valve from the feeding mechanism 21 to the first carrier 12.

[0046] Specifically, refer to Figure 2 As shown, the feeding mechanism 21 includes a clip structure 211 and a lifting structure 212. The clip structure 211 is provided with a chute 2111 and a first sensing element 2112. The first sensing element 2112 is provided at the top of the clip structure 211 and corresponds to the chute 2111. A plurality of explosion-proof valves can be stacked in the chute 2111. The lifting structure 212 is provided with a first driving member (not shown in the figure), a lifting member 2121 and a hand piece 2122. The explosion-proof valve and the lifting member 2121 are located in the chute 2111. The explosion-proof valve is located above the lifting member 2121. The first sensing element 2112 is connected to the first driving member by signal. The first driving member drives the lifting member 2121 to lift the explosion-proof valve. The hand piece 2122 is connected to the lifting member 2121 and is located outside the chute 2111.

[0047] When taking materials from the first carrier 12, the end of the first material taking mechanism moves to the top of the chute 2111, and moves the top explosion-proof valve in the chute 2111 to the first carrier. At this time, the first sensing element 2112 can detect the movement of the first material taking mechanism, and start the first driving member to move upward by a distance equivalent to the thickness of the explosion-proof valve, that is, the lifting member 2121 pushes the explosion-proof valve upward, thereby realizing the continuous supply of the explosion-proof valve. By setting the handpiece 2122, the position of the lifting member 2121 can be manually adjusted, which is convenient for the later maintenance of the feeding mechanism 21.

[0048] In this embodiment, the first sensing element 2112 is set as an infrared sensor. When the infrared sensor is blocked by the first material taking mechanism for two seconds and then leaves, it can command the first driving member to move up; when the chute 2111 is empty, the infrared sensor will sense the first driving member for a long time and an alarm will be issued. At this time, it is necessary to add material to the chute 2111. The first driving member can use a direct-acting cylinder, which has high moving accuracy, mature products, and can be well controlled.

[0049] According to the characteristics of the explosion-proof valve being small in thickness, easy to bend and light in weight, a suction cup is provided at the end of the first material picking mechanism. The suction cup mechanism is simple, has high picking efficiency and can reduce the wear on the explosion-proof valve. Suction cups can be used at the ends of other material picking mechanisms in this embodiment and will not be described in detail hereinafter.

[0050] Preferably, the first loading assembly 2 further includes a second turntable 22, and a plurality of feeding mechanisms 21 are provided, and the plurality of feeding mechanisms 21 are evenly distributed around the second turntable 22. When one of the feeding mechanisms 21 is empty, the empty feeding mechanism 21 is driven away from the loading area by the rotation of the second turntable 22, and another full feeding mechanism 21 is driven into the loading area to continue feeding, so that the feeding can continue when the empty feeding mechanism 21 is fed, thereby ensuring the continuous feeding of the first loading assembly 2 and ensuring the production efficiency. Optionally, two, three, four, etc. feeding mechanisms 21 can be provided.

[0051] After the first material-picking mechanism places the explosion-proof valve on the first carrier 12, the first turntable 11 rotates one position, so that the first carrier 12 and the explosion-proof valve enter the first identification station. The explosion-proof valve feeding device also includes a first identification element, which is arranged at the first identification station and corresponds to the first carrier 12, and can identify the front and back of the explosion-proof valve on the first carrier 12. Specifically, the first identification element can be set as an image acquisition element (such as a CCD camera, etc.), and the first identification element compares the image of the explosion-proof valve with the database to determine whether there is an error in the front and back of the explosion-proof valve. After the image acquisition is completed, the first turntable 11 continues to rotate one position, driving the first carrier 12 and the explosion-proof valve to enter the flipping station.

[0052] Furthermore, the explosion-proof valve feeding device further includes a flipping assembly 3, which is located at the flipping station, and is connected to the first identification element signal, and the flipping assembly 3 can flip the explosion-proof valve located on a corresponding first carrier 12. The first identification element can send the judgment result of whether the explosion-proof valve has a positive and negative error to the flipping assembly 3. If the explosion-proof valve is correct, the flipping assembly 3 is not started, and the first turntable 11 drives the first carrier 12 and the explosion-proof valve to the next station; if the explosion-proof valve is wrong, the flipping assembly 3 is started to flip the explosion-proof valve.

[0053] In this embodiment, refer to Figure 3 and Figure 4 As shown, the flip assembly 3 includes a turning mechanism 31, a first storage platform 32, a second material picking mechanism and a third material picking mechanism. The second material picking mechanism is used to move the explosion-proof valve from the first carrier 12 to the turning mechanism 31, the turning mechanism 31 is used to turn the explosion-proof valve, the first storage platform 32 is used to place the turned explosion-proof valve, and the third material picking mechanism is used to move the explosion-proof valve from the first storage platform 32 to the first carrier 12.

[0054] It should be noted that the flipping mechanism 31 and the first storage table 32 correspond to one rotation position respectively, that is, when the second material picking mechanism takes the explosion-proof valve and places it on the flipping mechanism 31, the explosion-proof valve is flipped by the flipping mechanism 31 and moved to the first storage table 32. At this time, the first turntable 11 rotates one position, so that when the third material picking mechanism moves the explosion-proof valve from the first storage table 32 to the first carrier 12, the explosion-proof valve can return to the original first carrier 12, realizing a one-to-one correspondence between the explosion-proof valve and the first carrier 12, thereby ensuring the orderliness and traceability of material loading.

[0055] Specifically, the flip mechanism 31 includes a support member 311, a second driving member 312, a rotating member 313, and a second sensing element 314. The support member 311 is used to support the second driving member 312 and the rotating member 313. The explosion-proof valve is fixed to the rotating member 313. The second driving member 312 flips the rotating member 313. The second sensing element 314 is installed on the rotating member 313. Optionally, the rotating member 313 includes an extension portion 3131 and a platform portion 3132. The extension portion 3131 is connected between the platform portion 3132 and the second driving member 312. The platform portion 3132 is used to fix the explosion-proof valve to be flipped. The second sensing element 314 is connected to the platform portion. The extension portion 3131 is set at an angle to the rotation axis of the second driving member 312.

[0056] When the explosion-proof valve needs to be turned over, the second material-retrieving mechanism moves the explosion-proof valve to the platform portion 3132. At this time, the second sensing element 314 can sense and activate the suction cup on the platform portion 3132 to fix the explosion-proof valve to prevent the explosion-proof valve from falling after turning over, and then activate the second driving member 312 to turn it over. Since the extension portion 3131 and the rotation axis of the second driving member 312 are set at an angle, the position of the platform portion 3132 changes after the second driving member 312 rotates 180°. At this time, the platform portion 3132 is located above the explosion-proof valve, and the bottom of the explosion-proof valve can face the first storage platform 32, reducing other moving steps and improving production efficiency. In this embodiment, the second driving member 312 is configured as a rotary cylinder, and the product is mature and easy to select.

[0057] Optionally, the first placement table 32 includes a support structure 321, a receiving member 322, a third driving member 323 and a third sensing element 324, the third sensing element 324 is signal-connected to the third driving member 323, the support structure 321 is used to support the receiving member 322 and the third driving member 323, the third driving member 323 drives the receiving member 322 to rise and fall, and the receiving member 322 is used to place an explosion-proof valve.

[0058] When the flipping mechanism 31 turns over the explosion-proof valve and moves it above the first storage platform 32, the third sensing element 324 can sense it, thereby starting the third driving member 323 to lift the receiving member 322, so that the receiving member 322 can abut against the flipped explosion-proof valve. After the flipping mechanism 31 releases the explosion-proof valve, the third driving member 323 drives the receiving member 322 to descend, so that the explosion-proof valve falls back to be flush with the top surface of the support structure 321. Finally, the third material picking mechanism sends the explosion-proof valve on the receiving member 322 back to the first carrier 12.

[0059] Optionally, the first storage platform 32 further includes a clamping member 325, which is disposed on the support structure 321 and can clamp or release the receiving member 322. When the receiving member 322 needs to rise or fall, the clamping member 325 is loosened. When the receiving member 322 stops moving, the clamping member 325 clamps the receiving member 322 to ensure the stability of the receiving member 322. In this embodiment, four clamping members 325 are provided, and the four clamping members 325 are disposed around the receiving member 322.

[0060] After the explosion-proof valve is adjusted forward and backward, the first turntable 11 continues to rotate one position to move the explosion-proof valve to the first shaping station. The explosion-proof valve feeding device also includes a first shaping mechanism, which is arranged at the first shaping station, and the first shaping mechanism is correspondingly arranged on a first carrier 12, and the first shaping mechanism is used to adjust the shape of the explosion-proof valve.

[0061] Specifically, the first shaping mechanism includes a fourth driving member and a pressing member. The pressing member is arranged above the explosion-proof piece. The fourth driving member can drive the pressing member to rise or fall. When the explosion-proof piece enters the first shaping station, the pressing member descends and applies pressure to the explosion-proof valve to flatten the explosion-proof valve to ensure the flatness of the explosion-proof valve.

[0062] After the explosion-proof valve is shaped, the first turntable 11 continues to rotate one position to move the explosion-proof valve to the second identification station. Since the opening direction of the explosion-proof valve needs to match the injection hole on the cover plate, it is necessary to adjust the opening direction of the explosion-proof valve before welding the explosion-proof valve. The second identification station is provided with a second identification element, and the second identification element is arranged corresponding to a first carrier 12, which can identify the opening direction of the explosion-proof valve and calculate the angle that needs to be adjusted. The second identification element can be set as an image acquisition element (such as a CCD camera, etc.), and can use the same model as the first identification element to improve matching efficiency.

[0063] Furthermore, the explosion-proof valve continues to rotate with the first turntable 11 to the discharge station. The discharge station is provided with a discharge assembly 4, which is connected to the second identification element signal, and can clamp and rotate the explosion-proof valve on the first carrier 12, and can move the explosion-proof valve to the next process.

[0064] The discharging assembly 4 includes a rotating head, a fourth moving mechanism and a second storage platform 41. The rotating head can pick up the explosion-proof valve and rotate according to the angle calculated by the second identification element so that the opening direction of the explosion-proof valve is correct. The fourth moving mechanism can move the rotating head, move the rotating head and the explosion-proof valve to the top of the second storage platform 41, and the second storage platform 41 receives the explosion-proof valve to realize the loading of the explosion-proof valve. The structure of the second storage platform 41 can be set with reference to the first storage platform 32, and will not be repeated here.

[0065] When using the explosion-proof valve feeding device, the first turntable 11 moves the first carrier 12 and the explosion-proof valve to pass through the first identification element, the flip assembly 3, the second identification element and the discharge assembly 4 in sequence, and can automatically identify and adjust the front and back and the opening direction of the explosion-proof valve during feeding, avoiding the need to adjust the front and back and the opening direction of the explosion-proof valve again after discharging, effectively improving the accuracy of the explosion-proof valve feeding positioning, ensuring the production efficiency of the explosion-proof valve assembly, improving the product qualification rate, and ensuring the safe use of batteries.

[0066] This embodiment also provides an explosion-proof valve welding device, including a welding device 500, a cover plate feeding device 600, a shaping and unloading device 700 and the above-mentioned explosion-proof valve feeding device, the cover plate feeding device 600 is used to convey the cover plate to the welding device 500, the explosion-proof valve feeding device is used to convey the explosion-proof valve to the welding device 500, the welding device 500 is used to weld the cover plate and the explosion-proof valve, and the shaping and unloading device 700 is used to trim the shape of the battery cover and unload.

[0067] Specifically, the welding device 500 includes a third turntable 510 and multiple second carriers 520. The cover plate and the explosion-proof valve can be placed on the second carrier 520. The multiple second carriers 520 are evenly distributed on the third turntable 510. Multiple workstations are evenly distributed around the third turntable 510. Each workstation corresponds to at least one second carrier 520. The multiple workstations include at least a second loading station, a feeding station, a welding station and a shaping and unloading station arranged in sequence. After the third turntable 510 drives the second carrier 520 to pass through all the workstations in sequence, the welded top cover is transferred out at the shaping and unloading station.

[0068] The cover plate loading device 600 is arranged at the second loading station, and the cover plate loading device 600 includes a second loading component 610 and a transfer mechanism 620. The second loading component 610 and the transfer mechanism 620 can place the cover plate on the second carrier 520. The structure of the second loading component 610 is consistent with the structure of the first loading component 2, which will not be repeated here.

[0069] After the cover sheet is placed on the second carrier, the third turntable 510 rotates to move the cover sheet to the feeding station. The feeding station is provided with a fifth material taking mechanism, which can move the explosion-proof valve placed on the second storage platform 41 onto the cover sheet.

[0070] Furthermore, the cover plate and the explosion-proof valve enter the welding station with the third rotating disk 510. The welding station is provided with a plurality of welding manipulators for welding the cover plate and the explosion-proof valve, realizing automatic welding of the battery top cover and improving the efficiency of welding production. Optionally, the third rotating disk 510 can rotate clockwise or counterclockwise to achieve precise stopping and starting.

[0071] After the explosion-proof valve and the cover plate are welded, the third turntable 510 rotates to the shaping and unloading station. The shaping and unloading device 700 is arranged at the shaping and unloading station. The shaping and unloading device 700 includes a second shaping mechanism 710 and an unloading mechanism 720. The second shaping mechanism 710 is used to trim the shape of the battery top cover, and the unloading mechanism 720 is used to move the battery top cover from the second carrier 520 to the next process.
