[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] Please refer to Figures 1 to 12 , an explosion-proof valve welding equipment, comprising a frame 001, a cover plate coding and transporting device 2 and a turntable 4, wherein the cover plate coding and transporting device 2 is arranged on the frame 001; the turntable 4 is rotatably installed on the frame 001, and a plurality of explosion-proof valve welding fixtures 1 are evenly distributed on the circumference of the turntable 4; it also includes a cover plate positioning mechanism 6, an explosion-proof valve feeding mechanism 5, an explosion-proof valve positioning mechanism 7, a welding mechanism 8 and a blanking mechanism 9 which are sequentially arranged along the rotation direction of the turntable 4, and when the explosion-proof valve welding fixture 1 on the turntable 4 rotates with the turntable 4, it can pass through the lower area of ​​the cover plate positioning mechanism 6, the explosion-proof valve feeding mechanism 5, the explosion-proof valve positioning mechanism 7, the welding mechanism 8 and the blanking mechanism 9 in sequence; the cover plate coding and transporting device 2 is arranged opposite to the turntable 4, and a cover plate feeding mechanism 3 is arranged between the two. In this embodiment, the cover plate positioning mechanism 6, the explosion-proof valve feeding mechanism 5, the explosion-proof valve positioning mechanism 7, the welding mechanism 8, the cover plate feeding mechanism 3 and the unloading mechanism 9 are all arranged on the frame 001. When in use, the cover plate coding and transporting device 2 codes the battery cover plate 23 and transports it to the cover plate feeding mechanism 3, the cover plate feeding mechanism 3 grabs the battery cover plate 23 and transports it to the explosion-proof valve welding fixture 1, and then the turntable 4 rotates so that the battery cover plate 23 on the explosion-proof valve welding fixture 1 passes through the cover plate positioning mechanism 6, the explosion-proof valve feeding mechanism 5, the explosion-proof valve positioning mechanism 7, the welding mechanism 8 and the unloading mechanism 9 in sequence, thereby realizing the rapid welding of the explosion-proof valve on the battery cover plate 23. Here, a plurality of explosion-proof valve welding fixtures 1 are arranged on the turntable 4, which can realize the multi-station production and processing of the battery cover plate 23, which is conducive to improving the automated production efficiency of the explosion-proof valve welding.

[0040] Specifically, Figures 2 to 7As shown, the welding fixture 1 for explosion-proof valves includes a base frame 10 and a clamping member 11, wherein at least one welding station area 121 is provided on the base frame 10 for assembling the battery cover plate 23; the clamping member 11 is provided corresponding to the welding station area 121 for fixing the battery cover plate 23; the clamping member 11 includes at least two pressing claws 110, which are rotatably mounted on the base frame 10 and are located on at least one side of the welding station area 121 corresponding thereto; the welding fixture 1 for explosion-proof valves also includes a driving member for driving the pressing claws 110 to switch between an open state and a clamping state in a rotating manner; when the pressing claws 110 are in an open state, the projection of the pressing claws 110 in a direction perpendicular to the welding station area 121 is outside the welding station area 121. As shown in FIG. Figure 2 As shown, there are two welding stations 121, and the two welding stations 121 are spaced apart along the first direction X. Here, the pressing claw 110 is located on at least one side of the welding station 121, which means that the pressing claw 110 can be set not only at the end of the battery cover 23 in the length direction, but also at the side of the battery cover 23 in the width direction, so that the pressing claw 110 can be set in the specific position of the battery cover 23 in the length direction according to the specific position of the explosion-proof valve to better press the battery cover 23 to avoid the battery cover 23 from warping. Occurs, ensuring the negative pressure adsorption effect of the explosion-proof valve, which is beneficial to ensuring the welding quality of the explosion-proof valve and the battery cover 23; when the pressure claw 110 is in the open state, the projection of the pressure claw 110 in the direction perpendicular to the welding station area 121 is outside the welding station area 121, which ensures that the clamp has a large range of air avoidance after the pressure claw 110 is opened, ensuring the smooth loading and unloading of the battery cover 23; at the same time, at least one welding station area 121 can meet the simultaneous assembly and welding of the explosion-proof valve of at least one battery cover 23, which is beneficial to improving work efficiency. In other embodiments, the number and arrangement of the welding station areas 121 can be specifically set according to processing needs, and are not limited to Figure 2 The structural form shown.

[0041] It should be noted that, in this embodiment, Figure 2 As shown, the length direction of the battery cover plate 23 is the second direction Y, and the width direction of the battery cover plate 23 is the first direction X.

[0042] In this embodiment, all the pressing jaws 110 are linked together. The linkage of all the pressing jaws 110 can realize synchronous movement of all the pressing jaws 110, which reduces the driving cost of the pressing jaws 110 and is conducive to improving work efficiency.

[0043] Furthermore, if Figure 3 and Figure 6As shown, the pressing claw 110 is provided with a fixed rotating shaft 112 and a sliding rotating shaft 111, the fixed rotating shaft 112 is parallel to the sliding rotating shaft 111, the pressing claw 110 is rotatably mounted on the base frame 10 via the fixed rotating shaft 112, and the driving member acts on the sliding rotating shaft 111; the pressing claw 110 is provided with a clamping plane 1101, the fixed rotating shaft 112 is between the sliding rotating shaft 111 and the clamping plane 1101; the plane where the central axis of the fixed rotating shaft 112 and the central axis of the sliding rotating shaft 111 are located is defined as a reference plane 1102, and the angle between the clamping plane 1101 and the reference plane 1102 is α, 0°≤α≤90°. Preferably, 30°≤α≤60°, and more preferably, α=45°.

[0044] like Figure 2 , Figure 3 and Figure 7 As shown, when the pressure claw 110 is in an open state, the sliding shaft 111 is at the lower side of the fixed shaft 112; when the pressure claw 110 is in a clamped state, the sliding shaft 111 is at the upper side of the fixed shaft 112; when 30°≤α≤60°, a dead point can be prevented when the pressure claw 110 is driven to rotate, and at the same time, during the rotation of the pressure claw 110, the movement range of the sliding shaft 111 in the first direction X is small, which is conducive to improving the compactness of the assembly of the driving member and the pressure claw 110. In this embodiment, based on the structural design of the aforementioned explosion-proof valve welding fixture 1, its occupied space can be effectively reduced, which is conducive to arranging more stations of the explosion-proof valve welding fixture 1 along the circumferential direction on the turntable 4, thereby further improving the production efficiency of the explosion-proof valve welding equipment.

[0045] In this embodiment, the driving member includes a driving block 16 and an integrated board 13. The driving block 16 is arranged corresponding to the pressing claw 110. All driving blocks 16 are fixedly mounted on the integrated board 13. A sliding groove 161 is provided on the driving block 16. The sliding shaft 111 is slidably embedded in the sliding groove 161. The integrated board 13 is adjustably arranged on the base frame 10. Figure 3 As shown, all the driving blocks 16 are integrated on the integrated board 13 to realize the linkage of the driving blocks 16, thereby realizing the linkage of the pressure claw 110. When in use, the driving block 16 drives the sliding shaft 111 to rotate around the fixed shaft 112. During the process, the sliding shaft 111 can move in the sliding groove 161 along the extension direction of the sliding groove 161 to realize the motion transmission from the translation of the driving block 16 to the rotation of the pressure claw 110.

[0046] In order to reduce friction, Figure 3 As shown, a roller 1111 is mounted on the sliding shaft 111 , and the roller 1111 can roll or slide on the inner wall of the sliding groove 161 .

[0047] In this embodiment, the driving member also includes a driving source (not shown in the figure), which is arranged on the base frame 10, and is used to drive the integrated board 13 to move longitudinally, so that the clamping plane 1101 is close to or away from the welding station area 121 in the manner that the sliding shaft 111 slides in the slide groove 161 and the pressing claw 110 rotates around the central axis of the fixed shaft 112. Optionally, the driving source includes but is not limited to a telescopic member such as a cylinder, a hydraulic cylinder or an electric push rod, or other existing mechanical structures that can drive the integrated board 13 to move longitudinally. Figure 2 As shown, in this embodiment, the longitudinal direction is the third direction Z.

[0048] Furthermore, the base frame 10 includes a longitudinal plate 101 and a transverse plate 102 connected to each other, and the welding station area 121 and the pressing claw 110 are both arranged on the transverse plate 102; the longitudinal plate 101 is provided with a first slide rail 172 extending in the longitudinal direction, and the integrated board 13 is provided with a first slider 171 adapted to the first slide rail 172. Preferably, the longitudinal plate 101 and the transverse plate 102 are perpendicular. In this way, the assembly of the first slide rail 172 extending in the longitudinal direction is convenient, and the structures of the first slider 171 and the first slide rail 172 are simple, which can ensure the stability of the integrated board 13 in the longitudinal movement.

[0049] Furthermore, a preload spring 14 is provided between the base frame 10 and the integrated board 13, and the preload spring 14 acts on the integrated board 13 so that the pressing plane 1101 has a movement tendency to approach the welding station area 121. Figure 2 and Figure 7 As shown, when the pressure claw 110 is in the open state, the preload spring 14 is stretched to store energy. When the pressure claw 110 switches from the open state to the clamped state, the preload spring 14 can act on the integrated board 13 to make it move quickly upward in the longitudinal direction so that the pressure claw 110 can quickly reach the clamped state.

[0050] It should be noted that the pre-tensioning spring 14 here can realize part of the functions of the aforementioned driving source, that is, the pre-tensioning spring 14 always acts on the integrated board 13 to ensure that the pressure claw 110 always remains in a clamped state. When the pressure claw 110 needs to be switched to an open state, it is only necessary to pull the integrated board 13 downward in the longitudinal direction through external force.

[0051] In this embodiment, the integrated board 13 includes a first plate 131 and a second plate 132 connected to each other, the first plate 131 is parallel to the longitudinal plate 101, the second plate 132 is parallel to the transverse plate 102, the driving block 16 is connected to the second plate 132 through an extension rod 133, and the first slider 171 is installed on the first plate 131.

[0052] In this embodiment, a through hole 1021 is formed through the transverse plate 102 , and the driving block 16 can pass through the through hole 1021 .

[0053] In this embodiment, a negative pressure hole 1210 is provided through the horizontal plate 102, and the negative pressure hole 1210 extends to the welding station area 121 and is connected to the explosion-proof valve installation area. The negative pressure hole 1210 is externally connected to a negative pressure source. Under the action of the negative pressure source, the negative pressure hole 1210 can generate negative pressure in the explosion-proof valve installation area to adsorb and fix the explosion-proof valve.

[0054] In this embodiment, a base plate 12 is provided on the horizontal plate 102, and a welding station area 121 is located on the base plate 12. The base plate 12 corresponds to the welding station area 121. When there are multiple welding station areas 121, the multiple base plates 12 can be provided independently or integrally. The method of providing the welding station area 121 on the base plate 12 facilitates the replacement of the explosion-proof valve and the battery cover plate 23.

[0055] like Figure 3 As shown, a fork frame 15 is provided on the transverse plate 102 , and the pressing claw 110 is rotatably mounted on the fork frame 15 via a fixed rotating shaft 112 .

[0056] In this embodiment, the transverse plate 102 is located on the upper side of the turntable 4, and the longitudinal plate 101 passes through the turntable 4 and extends to the bottom of the turntable 4; the longitudinal plate 101 and / or the transverse plate 102 are fixedly connected to the turntable.

[0057] like Figures 8 to 12 As shown, the cover plate coding transfer device 2 includes an upstream conveyor belt 21, a downstream conveyor belt 22 and a flipping mechanism 25. A coding mechanism 24 is arranged on the side of the upstream conveyor belt 21 for coding the battery cover plate 23 on the upstream conveyor belt 21; the flipping mechanism 25 is arranged between the upstream conveyor belt 21 and the downstream conveyor belt 22. The flipping mechanism 25 can rotate unidirectionally to flip the battery cover plate 23 on the upstream conveyor belt 21 and then transport it to the downstream conveyor belt 22. In this embodiment, the coding mechanism 24 is used to engrave the battery cover 23 on the upstream conveyor belt 21. After the coded battery cover 23 moves to a predetermined position toward the downstream conveyor belt 22 under the action of the upstream conveyor belt 21, the flipping mechanism 25 grabs the battery cover 23 at the predetermined position and rotates 180° in one direction to realize the flipping of the battery cover 23 and transfer the battery cover 23 to the downstream conveyor belt 22, and then the coded and flipped battery cover 23 is transported to the explosion-proof valve welding station through the downstream conveyor belt 22 to facilitate the assembly and welding of the explosion-proof valve. The flipping mechanism 25 here realizes the flipping and transportation of the cover at the same time by unidirectional rotation, which can effectively improve production efficiency.

[0058] like Figure 8As shown, the upstream conveyor belt 21 includes two first synchronous belts 210 arranged at intervals, and the downstream conveyor belt 22 includes two second synchronous belts 220 arranged at intervals; the flip mechanism 25 includes an adsorption plate 250 rotatably installed between the upstream conveyor belt 21 and the downstream conveyor belt 22, the rotation axis of the adsorption plate 250 is between the upstream conveyor belt 21 and the downstream conveyor belt 22, and an adsorption portion 251 is provided on the adsorption plate 250. When the adsorption plate 250 rotates, the contour line of the adsorption portion 251 passes through the area between the two first synchronous belts 210, and at the same time, the contour line of the adsorption portion 251 passes through the area between the two second synchronous belts 220. In this way, when the adsorption portion 251 passes through the area between the synchronous belts, it is convenient to adsorb and grasp the battery cover plate 23 placed between the two first synchronous belts 210 and the two second synchronous belts 220. At the same time, the structural form of the adsorption portion 251 can be set as needed to achieve simultaneous grasping of multiple battery cover plates 23.

[0059] For example, in this embodiment, if Figure 8 and Fig. 9 As shown, the adsorption portion 251 includes a vacuum suction cup 2510. Two groups of vacuum suction cups 2510 may be provided at one end of the adsorption plate 250 in the length direction, so that two battery cover plates 23 can be grasped simultaneously.

[0060] like Figures 9 to 11 As shown, two adsorption parts 251 are provided on the adsorption plate 250, and the central axis of the adsorption plate 250 when rotating is defined as the rotation axis, and the two adsorption parts 251 are symmetrical about the rotation axis. In this embodiment, the adsorption plate 250 is rotatably installed between the upstream conveyor belt 21 and the downstream conveyor belt 22 through the flip shaft 255, and the rotation axis is the central axis of the flip shaft 255. With such a configuration, two cover plate transfers between the upstream conveyor belt 21 and the downstream conveyor belt 22 can be achieved when the adsorption plate 250 rotates one circle, which can further improve work efficiency.

[0061] like Figures 8 to 11 As shown, in this embodiment, in order to ensure the stability of the battery cover plate 23 and avoid the interference between the two adsorption parts 251, the bearing surface of the downstream conveyor belt 22 and the bearing surface of the upstream conveyor belt 21 have a height difference. The cover plate engraving and transporting device 2 also includes a base plate 20, and the upstream conveyor belt 21, the downstream conveyor belt 22 and the flip mechanism 25 are all installed on the base plate 20; the adsorption plate 250 is movably installed on the base plate 20 in the longitudinal direction. Fig.11As shown, when in use, after the adsorption portion 251 on the downstream conveyor belt 22 is separated from the battery cover plate 23, the downstream conveyor belt 22 carries away the battery cover plate 23. During the process, the adsorption plate 250 moves upward until the adsorption portion 251 close to the upstream conveyor belt 21 contacts the lower side of the battery cover plate 23 on the upstream conveyor belt 21 and stops the longitudinal movement.

[0065] like Figure 8 and Fig.12 As shown, the cover plate engraving and transporting device 2 also includes a first correction component 26 and a second correction component 27, wherein: the first correction component 26 includes two first correction mechanisms 261 arranged opposite to each other, the upstream conveyor belt 21 is located between the two first correction mechanisms 261, and the battery cover plate 23 on the upstream conveyor belt 21 passes through the area between the two first correction mechanisms 261 during the conveying process; the second correction component 27 includes two second correction mechanisms 271 arranged opposite to each other, the downstream conveyor belt 22 is located between the two second correction mechanisms 271, and the battery cover plate 23 on the downstream conveyor belt 22 passes through the area between the two second correction mechanisms 271 during the conveying process. In this embodiment, the first correction component 26 and the second correction component 27 are both used to adjust the posture of the battery cover plate 23 for easy grasping, and the structures of the two can be the same.
