Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and in particular to an explosion-proof valve feeding device and an explosion-proof valve welding equipment. Background Technology

[0002] To ensure the safe use of new energy batteries, explosion-proof valves are typically welded onto the battery cover. When a new energy battery malfunctions due to improper charging, a short circuit, or exposure to harsh environments such as high temperature and high pressure, the high-energy battery will generate a large amount of gas and its temperature will rise sharply. The gas will force open the explosion-proof valve to release pressure and cool down. The presence of the explosion-proof valve can greatly improve the safety performance of new energy batteries.

[0003] However, during the conveying and feeding process of explosion-proof valves, there is a possibility that the valves may be placed incorrectly in the opposite direction or with the correct opening orientation. Current explosion-proof valve feeding devices cannot avoid these risks. Not only is there a problem with poor assembly accuracy of the explosion-proof valves and cover plates, but it can also easily lead to large variations in the burst value after the explosion-proof valves and cover plates are welded together, affecting the pass rate and safety performance of the battery cover plates.

[0004] Therefore, there is an urgent need for an explosion-proof valve feeding device and an explosion-proof valve welding equipment to solve the above problems. Utility Model Content

[0014] The first turntable moves the first carrier, which passes sequentially through the first identification element, the flipping assembly, the second identification element, and the discharge assembly.

[0015] As an optional solution for the explosion-proof valve feeding device, the first feeding assembly includes a feeding mechanism and a first picking mechanism. The feeding mechanism is used to store a plurality of the explosion-proof valves, and the first picking mechanism is used to move the explosion-proof valves from the feeding mechanism to the first carrier.

[0016] As an optional solution for the explosion-proof valve feeding device, the feeding mechanism includes a clip structure and a lifting structure. The clip structure is provided with a slide groove, and the lifting structure is provided with a first driving member and a lifting member. The explosion-proof valve and the lifting member are located in the slide groove, and the first driving member drives the lifting member to lift the explosion-proof valve.

[0017] As an optional solution for the explosion-proof valve feeding device, the first feeding component also includes a second turntable, and multiple feeding mechanisms are provided, which are evenly distributed around the second turntable.

[0018] As an optional solution for the explosion-proof valve feeding device, the flipping assembly includes a flipping mechanism and a first placement platform. The flipping mechanism is used to flip the explosion-proof valve, and the first placement platform is used to place the flipped explosion-proof valve.

[0019] As an optional solution for the explosion-proof valve feeding device, the flipping mechanism includes a support member, a second driving member, and a rotating member. The support member is used to support the second driving member and the rotating member. The explosion-proof valve is fixed to the rotating member, and the second driving member flips the rotating member.

[0020] As an optional solution for the explosion-proof valve feeding device, the flipping assembly further includes a second material-retrieving mechanism and a third material-retrieving mechanism. The second material-retrieving mechanism is used to move the explosion-proof valve from the first carrier to the flipping mechanism, and the third material-retrieving mechanism is used to move the explosion-proof valve from the first placement platform to the first carrier.

[0021] As an optional solution for the explosion-proof valve feeding device, the first placement platform includes a support structure, a receiving component, and a third driving component. The support structure is used to support the receiving component and the third driving component. The third driving component drives the receiving component to rise and fall. The receiving component is used to place the explosion-proof valve.

[0022] As an optional solution for the explosion-proof valve feeding device, the explosion-proof valve feeding device further includes a first shaping mechanism, which is correspondingly disposed on one of the first carriers, and is used to adjust the shape of the explosion-proof valve.

[0023] Another objective of this invention is to provide an explosion-proof valve welding equipment that ensures accurate positioning of the explosion-proof valve with the cover plate during feeding, thereby guaranteeing production efficiency and improving product qualification rate.

[0024] To achieve this objective, the present invention adopts the following technical solution:

[0025] An explosion-proof valve welding device is provided, including a cover plate feeding device, a welding device, and the aforementioned explosion-proof valve feeding device.

[0026] The beneficial effects of this utility model are:

[0027] This invention provides an explosion-proof valve feeding device. A first feeding component places the explosion-proof valve onto a first carrier on a first turntable. The rotation of the first turntable sequentially transfers the first carrier and the explosion-proof valve to multiple workstations. After a first identification element captures an image of the explosion-proof valve, it analyzes whether the valve is correctly oriented. The valve then moves with the first turntable to the workstation corresponding to the flipping component. If the valve is incorrectly oriented, the flipping component removes the valve from the first carrier, flips it over, and places it back on the carrier. The valve then moves with the first turntable to the next workstation. If the valve is correctly oriented, the flipping component does not operate, and the valve moves directly to the next workstation. After a second identification element captures an image of the explosion-proof valve, it determines whether the valve's opening orientation meets the standard. The valve then moves with the first turntable to the discharge workstation. If the opening orientation of the explosion-proof valve does not meet the requirements, the discharge assembly, after clamping the valve, rotates it by a certain angle to adjust its opening orientation so that it is within a preset range before discharging it. If the opening orientation meets the requirements, the discharge assembly can directly discharge the valve. Using this explosion-proof valve feeding device, the device automatically identifies and adjusts the valve's orientation and opening direction during feeding, avoiding the need to readjust these aspects after discharging. This effectively improves the accuracy of the valve feeding and positioning, ensures efficient assembly, increases product qualification rates, and guarantees battery safety.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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 based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] like Figures 1 to 4 As shown, the explosion-proof valve feeding device in this embodiment includes a first turntable assembly 1. The first turntable assembly 1 includes a first turntable 11 and multiple first carriers 12. Explosion-proof valves can be placed on the first carriers 12. The multiple first carriers 12 are evenly distributed on the first turntable 11. Multiple workstations are evenly distributed around the first turntable 11, each workstation corresponding to at least one first carrier 12. The multiple workstations include at least a first feeding workstation, a first identification workstation, a flipping workstation, a shaping workstation, a second identification workstation, and a discharging workstation arranged sequentially. After the first turntable 11 drives the first carriers 12 and the explosion-proof valve through all the workstations in sequence, the explosion-proof valve is transferred to the next process at the discharging workstation. In this embodiment, eight first carriers 12 are provided on the first turntable 11, that is, the first turntable 11 has eight rotation positions. Among them, the flipping workstation corresponds to two rotation positions, and the remaining workstations are each corresponding to one rotation position. Furthermore, there is a gap between the feeding workstation and the discharging workstation, and the gap corresponds to one rotation position.

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

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

[0047] When retrieving material from the first carrier 12, the end of the first material-retrieving mechanism moves above the chute 2111, moving the uppermost explosion-proof valve in the chute 2111 onto the first carrier. At this time, the first sensing element 2112 can detect the movement of the first material-retrieving mechanism and activate the first driving component to move upward by a distance equivalent to the thickness of one explosion-proof valve. That is, the lifting component 2121 pushes the explosion-proof valve upward, thereby realizing the continuous supply of the explosion-proof valve. By setting the handheld component 2122, the position of the lifting component 2121 can be manually adjusted, which facilitates 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 handling mechanism for two seconds and then moves away, it can command the first driving component to move upward. When the chute 2111 is empty, the infrared sensor will issue an alarm if it senses the first driving component for an extended period of time, at which point the chute 2111 needs to be replenished with material. The first driving component can be a direct-acting cylinder, which has high movement accuracy, is a mature product, and can be well controlled.

[0049] Based on the characteristics of explosion-proof valves being thin, easy to bend, and lightweight, the end of the first material handling mechanism is set as a suction cup. The suction cup mechanism is simple, has high picking efficiency, and can reduce wear on the explosion-proof valve. In this embodiment, suction cups can also be used at the ends of other material handling mechanisms, which will not be described in detail hereafter.

[0050] Preferably, the first feeding assembly 2 also includes a second turntable 22, and multiple feeding mechanisms 21 are provided, which are evenly distributed around the second turntable 22. When one of the feeding mechanisms 21 is empty, the rotation of the second turntable 22 moves the empty feeding mechanism 21 away from the feeding area, and moves another full feeding mechanism 21 into the feeding area to continue feeding. This ensures continuous feeding when adding material to the empty feeding mechanism 21, thereby guaranteeing continuous feeding of the first feeding assembly 2 and ensuring production efficiency. Optionally, two, three, or four feeding mechanisms 21 can be provided.

[0051] After the first material handling mechanism places the explosion-proof valve onto the first carrier 12, the first turntable 11 rotates one position, causing the first carrier 12 and the explosion-proof valve to enter the first identification station. The explosion-proof valve feeding device also includes a first identification element, which is located at the first identification station and corresponds to the first carrier 12, capable of identifying the orientation of the explosion-proof valve on the first carrier 12. Specifically, the first identification element can be an image acquisition element (such as a CCD camera). The first identification element compares an image of the explosion-proof valve with a database to determine if there is an error in the orientation of the explosion-proof valve. After image acquisition is completed, the first turntable 11 continues to rotate one position, driving the first carrier 12 and the explosion-proof valve into the flipping station.

[0052] Furthermore, the explosion-proof valve feeding device also includes a flipping assembly 3, which is located at the flipping station and is signal-connected to the first identification element. The flipping assembly 3 can flip the explosion-proof valve located on a corresponding first carrier 12. The first identification element can send the determination result of whether the explosion-proof valve is flipped correctly to the flipping assembly 3. If the explosion-proof valve is flipped correctly, the flipping assembly 3 is not activated, 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 flipped incorrectly, the flipping assembly 3 is activated to flip the explosion-proof valve.

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

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

[0055] Specifically, the flipping mechanism 31 includes a support member 311, a second drive member 312, a rotating member 313, and a second sensing element 314. The support member 311 supports the second drive member 312 and the rotating member 313. The explosion-proof valve is fixed to the rotating member 313. The second drive member 312 flips the rotating member 313. The second sensing element 314 is mounted on the rotating member 313. Optionally, the rotating member 313 includes an extension 3131 and a platform 3132. The extension 3131 is connected between the platform 3132 and the second drive member 312. The platform 3132 is used to fix the explosion-proof valve to be flipped. The second sensing element 314 is connected to the platform. The extension 3131 is angled to the rotation axis of the second drive member 312.

[0056] When the explosion-proof valve needs to be flipped, the second material handling mechanism moves the valve onto the platform 3132. At this time, the second sensing element 314 detects this and activates the suction cup on the platform 3132 to secure the valve, preventing it from falling after flipping. Then, the second drive component 312 is activated to flip the valve. Because the extension 3131 and the rotation axis of the second drive component 312 are angled, the position of the platform 3132 changes after the second drive component 312 rotates 180°. At this point, the platform 3132 is positioned above the explosion-proof valve, and the valve's lower surface is directly opposite the first placement platform 32, reducing other moving steps and improving production efficiency. In this embodiment, the second drive component 312 is a rotary cylinder, a mature product that is easy to select.

[0057] Optionally, the first shelf 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. The receiving member 322 is used to place the explosion-proof valve.

[0058] When the flipping mechanism 31 flips the explosion-proof valve and moves it above the first platform 32, the third sensing element 324 can sense it and activate 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 fall, so that the explosion-proof valve falls back to be flush with the top surface of the support structure 321. Finally, the third material handling mechanism sends the explosion-proof valve on the receiving member 322 back to the first carrier 12.

[0059] Optionally, the first shelf 32 further includes clamping members 325. The clamping members 325 are 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 members 325 release; when the receiving member 322 stops moving, the clamping members 325 clamp 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 arranged around the receiving member 322.

[0060] After the explosion-proof valve is adjusted in both directions, the first turntable 11 continues to rotate one position, moving the explosion-proof valve to the first shaping station. The explosion-proof valve feeding device also includes a first shaping mechanism, which is located at the first shaping station and is correspondingly located on a first carrier 12. 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 component and a pressing component. The pressing component is positioned above the explosion-proof sheet. The fourth driving component can drive the pressing component to rise or fall. When the explosion-proof sheet enters the first shaping station, the pressing component descends and applies pressure to the explosion-proof valve to flatten it and ensure its flatness.

[0062] After the explosion-proof valve is shaped, the first turntable 11 rotates one position, moving 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, the opening direction of the explosion-proof valve needs to be adjusted before welding. The second identification station is equipped with a second identification element, which corresponds to a first carrier 12. This second identification element 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), and can be the same model as the first identification element, improving selection efficiency.

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

[0064] The discharge assembly 4 includes a rotating head, a fourth moving mechanism, and a second loading platform 41. The rotating head can pick up the explosion-proof valve and rotate it according to the angle calculated by the second identification element, so that the opening of the explosion-proof valve faces the correct direction. The fourth moving mechanism can move the rotating head, moving the rotating head and the explosion-proof valve above the second loading platform 41, where the second loading platform 41 receives the explosion-proof valve, thus realizing the feeding of the explosion-proof valve. The structure of the second loading platform 41 can be set with reference to the first loading platform 32, and will not be described in detail here.

[0065] Using this explosion-proof valve feeding device, the first turntable 11 moves the first carrier 12 and the explosion-proof valve sequentially through the first identification element, the flipping assembly 3, the second identification element, and the discharge assembly 4. It can automatically identify and adjust the front and back and opening direction of the explosion-proof valve during feeding, avoiding the need to readjust the front and back and opening direction of the explosion-proof valve after discharging. This effectively improves the accuracy of the explosion-proof valve feeding and positioning, ensures the production efficiency of explosion-proof valve assembly, increases the product qualification rate, and ensures the safety of battery use.

[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 aforementioned explosion-proof valve feeding device. The cover plate feeding device 600 is used to feed the cover plate to the welding device 500, the explosion-proof valve feeding device is used to feed 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 plate and unload it.

[0067] Specifically, the welding device 500 includes a third turntable 510 and multiple second carriers 520. The second carriers 520 can hold cover plates and explosion-proof valves. 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 workstation, a feeding workstation, a welding workstation, and a shaping and unloading workstation arranged in sequence. After the third turntable 510 drives the second carriers 520 to pass through all the workstations in sequence, the welded top cover is delivered at the shaping and unloading workstation.

[0068] The cover plate feeding device 600 is set at the second feeding station. The cover plate feeding device 600 includes a second feeding component 610 and a transfer mechanism 620. The second feeding component 610 and the transfer mechanism 620 can place the cover plate on the second carrier 520. The structure of the second feeding component 610 is the same as that of the first feeding component 2, and will not be described in detail here.

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

[0070] Furthermore, the cover plate and explosion-proof valve enter the welding station along with the third turntable 510. The welding station is equipped with several welding robots for welding the cover plate and explosion-proof valve, realizing automatic welding of the battery top cover and improving welding production efficiency. Optionally, the third turntable 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 set 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 shape 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.

[0072] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
