DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model technical scheme will be described clearly and completely in combination with specific embodiments of the utility model and corresponding drawings below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0028] The technical scheme disclosed by each embodiment of the utility model will be described in detail below in combination with the drawings.

[0029] As Figures 1 to 5 The utility model discloses a clamp device, which is applied to battery production equipment and is used for clamping a battery to be processed. For example, the clamp device can be used for clamping a battery shell to realize welding operation of the battery shell; or the clamp device can be used for clamping positive and negative electrodes to realize welding operation of the electrodes. Of course, the clamp device can also be used for clamping a battery cell to realize welding operation of the battery cell. The clamping device in the application can also realize welding process of other components of the battery. Of course, the clamp device in the application is not limited to clamping for welding process, and can also be applied to other processing processes, which is not limited in the present application. The disclosed clamp device comprises a driving mechanism, a clamping piece 200, a clamping table 300 and a suction pipeline 400.

[0030] The clamping piece 200 and the clamping table 300 form a clamping space, the driving mechanism is connected with at least one of the clamping piece 200 and the clamping table 300, and the driving mechanism can drive at least one of the clamping piece 200 and the clamping table 300 to move close to or away from the other. The clamping piece 200 and the clamping table 300 form a clamping space. At this time, when the battery is clamped, the battery is located between the clamping piece 200 and the clamping table 300. The battery can be placed on the clamping table 300 first, and then the driving mechanism drives the distance between the clamping piece 200 and the clamping table 300 to decrease. At this time, the driving mechanism exerts a force to abut the battery on the clamping table 300, so as to clamp the battery. When the driving mechanism drives the distance between the clamping piece 200 and the clamping table 300 to increase, the clamping space is opened, so the battery can be taken out.

[0031] In one embodiment, the driving mechanism may include a first driving source 100 connected to the clamping member 200. The first driving source 100 can drive the clamping member 200 to move in a direction closer to or further away from the clamping table 300. Here, the first driving source 100 and the clamping table 300 can be mounted on the equipment frame of the battery production equipment; that is, the equipment frame serves as the mounting base for the components of the clamping device. Alternatively, the clamping device may also include a clamping frame, in which case the clamping frame serves as the mounting base for other components of the clamping device. The aforementioned first driving source 100 and clamping table 300 can be mounted on the clamping frame, and the clamping device is fixedly mounted on the equipment frame via the clamping frame.

[0032] In another embodiment, the driving mechanism may include a second driving source 600 connected to the clamping stage 300. The second driving source 600 can drive the clamping stage 300 to move in a direction toward or away from the clamping member 200. In this case, when clamping the battery, the second driving source 600 drives the clamping stage 300 to move toward the clamping member 200, such as... Figure 1 As shown, the second drive source 600 drives the clamping stage 300 to rise. At this time, the clamping member 200 and the clamping stage 300 move closer to each other, thereby clamping the battery.

[0033] Alternatively, the driving mechanism may include a first driving source 100 and a second driving source 600. The second driving source 600 can adjust the height of the clamping table 300. During the clamping operation, the second driving source 600 maintains the height of the clamping table 300, with only the clamping member 200 descending. The first driving source 100 drives the clamping member 200 to move towards the clamping table 300, such as... Figure 1 As shown, the first drive source 100 drives the clamping member 200 to descend. The second drive source 600 drives the clamping stage 300 to move toward the clamping member 200, as... Figure 1 As shown, the second drive source 600 drives the clamping stage 300 to rise. At this time, the clamping member 200 and the clamping stage 300 move closer to each other, thereby clamping the battery. Alternatively, the second drive source 600 can adjust the height of the clamping stage 300, so that during the clamping operation, the second drive source 600 maintains the height of the clamping stage 300, and only the clamping member 200 descends.

[0034] Optionally, the first drive source 100 and the second drive source 600 can be power structures such as linear motors, pneumatic cylinders, and hydraulic cylinders. Of course, the first drive source 100 and the second drive source 600 can also be other power structures, which are not limited in this article.

[0035] The clamping stage 300 in this application can be a block structure. Of course, the clamping stage 300 can also be set to the same structure as the clamping member 200. This article does not limit the specific structure of the clamping stage 300.

[0036] At least one of the clamping member 200 and the clamping table 300 is provided with a smoke suction hole 500, which is in communication with the suction pipeline 400. The smoke suction hole 500 has an air inlet and an air outlet, and the air outlet is in communication with the suction pipeline 400. At this time, the suction pipeline 400 can provide negative pressure for the smoke suction hole 500, so that particulate matter and smoke will be sucked into the smoke suction hole 500 from the air inlet, then enter the suction pipeline 400 through the air outlet, and then be discharged through the suction pipeline 400. Here, the suction pipeline 400 can be in communication with the factory exhaust end, which can provide negative pressure for the suction pipeline, so as to make the smoke suction hole 500 have negative pressure. The factory exhaust end is provided with a smoke and particulate matter filtering or collecting component, so as to collect the smoke and particulate matter. The filtering or collecting component here can be a filter screen, a dust collecting box or other filtering or collecting components, which are not limited herein. Of course, the suction pipeline 400 can also be connected with a suction pump or a vacuum pump, so as to realize the negative pressure of the suction pipeline 400. The specific way of realizing the negative pressure of the suction pipeline 400 is not limited herein.

[0037] In the embodiments disclosed in the present application, the clamp device can adsorb and collect the smoke and particulate matter generated during the welding process, thereby avoiding the diffusion of the smoke and particulate matter in the environment, optimizing the production working environment of the operator, reducing the physical harm to the operator, and ensuring the safety of the operator.

[0038] In addition, the clamp device can adsorb and collect the smoke and particulate matter generated during the welding process, which also avoids the risk of welding particulate matter gathering on the welding surface of the battery, thereby being more conducive to realizing the self-cleaning performance of the battery process and being more conducive to providing the welding quality.

[0039] In one scheme, the clamping member 200 can include a connecting bracket 210 and a clamping jaw body 230. The driving shaft of the driving mechanism can be fixedly connected with the connecting bracket 210, and the driving shaft of the driving mechanism herein specifically refers to the driving shaft of the first driving source 100. The clamping jaw body 230 can be connected with the connecting bracket 210, and the clamping jaw body 230 is oppositely arranged with the clamping table 300, and the clamping jaw body 230 and the clamping table 300 form a clamping space. At this time, the first driving source 100 can drive the clamping jaw body 230 to move through the connecting bracket 210, and the clamping jaw body 230 can form a clamping space with the clamping table 300.

[0040] In another alternative embodiment, the clamping member 200 can include a connecting bracket 210, an elastic buffer 220, and a clamping jaw body 230. The driving shaft of the first driving source 100 is fixedly connected with the connecting bracket 210. The clamping jaw body 230 is elastically connected with the connecting bracket 210 through the elastic buffer 220. The clamping jaw body 230 is oppositely arranged with the clamping table 300. The clamping jaw body 230 and the clamping table 300 form a clamping space.

[0041] In a specific clamping operation, the first driving source 100 drives the connecting bracket 210 to move towards the clamping table 300. The connecting bracket 210 drives the clamping jaw body 230 to move together through the elastic buffer 220. When the clamping jaw body 230 contacts the battery, the reaction force of the battery on the clamping jaw body 230 can compress the elastic buffer 220. The elastic force generated by the elastic buffer 220 acts on the clamping jaw body 230. Therefore, the elastic buffer 220 exerts a force on the clamping jaw body 230, thereby clamping the battery.

[0042] In this scheme, the elastic buffer 220 can buffer the clamping jaw body 230 during clamping in the process of clamping the battery by the clamping member 200 and the clamping table 300. Rigid collision between the clamping jaw body 230 and the battery is avoided, thereby avoiding the risk of excessive extrusion deformation or damage of the battery during clamping. Therefore, the safety and reliability of battery clamping are improved.

[0043] Optionally, the elastic buffer 220 can be a spring, a spring sheet, or other elastic structure. Of course, the elastic buffer 220 can also be other structures, which are not limited herein.

[0044] Further, the clamping member 200 can further include a guide rail 240 and a sliding block 250. The guide rail 240 can be fixedly connected with the connecting bracket 210. Optionally, the guide rail 240 can be connected with the connecting bracket 210 through rivets, bolts, or other components. The extension direction of the guide rail 240 can be parallel to the elastic expansion direction of the elastic buffer 220. The sliding block 250 can slide with the guide rail 240 in the extension direction of the guide rail 240. The sliding block 250 can be fixedly connected with the clamping jaw body 230.

[0045] In this scheme, the guide rail 240 can guide the moving direction of the clamping jaw body 230, thereby avoiding the risk of shaking of the clamping jaw body 230, and improving the stability of the clamping jaw body 230.

[0046] In the above scheme, the clamping jaw body 230 can be an integral structure. The clamping jaw body 230 can be integrally formed by casting or machining.

[0047] In another alternative embodiment, the clamping jaw body 230 can comprise a fixed block 231 and a pressing jaw 232, and the end of the elastic buffer 220 away from the connecting bracket 210 can be connected to the fixed block 231. The pressing jaw 232 can be located at the end of the fixed block 231 away from the elastic buffer 220, and the pressing jaw 232 can be detachably connected to the fixed block 231, and the pressing jaw 232 is used to form a clamping space with the clamping table 300. The fixed block 231 here is used to realize the connection of the elastic buffer 220, and the pressing jaw 232 is used to form a clamping space with the clamping table 300.

[0048] In this scheme, the pressing jaw 232 is used to press the battery, so the pressing jaw 232 is easy to wear out. At this time, the pressing jaw 232 and the fixed block 231 are in a detachable structure, so only the worn-out pressing jaw 232 needs to be replaced, without the need to replace the entire clamping jaw body 230. That is, the fixed block 231 is not easy to wear out, so there is no need to replace the fixed block 231. Therefore, the detachable structure of the pressing jaw 232 and the fixed block 231 in this scheme can reduce the maintenance cost of the clamping device.

[0049] Alternatively, the pressing jaw 232 and the fixed block 231 can be connected by a buckle, a bolt or other detachable structure, which is not limited in this article.

[0050] In an alternative scheme, the above-mentioned smoke suction hole 500 can be provided on the fixed block 231.

[0051] Alternatively, in another alternative embodiment, the above-mentioned smoke suction hole 500 can be provided on the pressing jaw 232. In this scheme, since the pressing jaw 232 is closer to the welding area of the battery, it is more beneficial to adsorb smoke and particulate matter by providing the smoke suction hole 500 on the pressing jaw 232, thereby further reducing the diffusion of smoke and particulate matter.

[0052] In the above-mentioned embodiments, the pressing jaw 232 can be a block structure, and of course the pressing jaw 232 can also be a long strip structure, for example, a rectangular strip structure.

[0053] In another alternative, the pressure jaw 232 can include a connecting portion 2321 and a pressing portion 2322, the connecting portion 2321 is detachably connected with the fixing block 231. The pressing portion 2322 can have a first end 2322a and a second end 2322b oppositely arranged, the first end 2322a is towards the clamping table 300, at this time, the end surface of the first end 2322a is opposite to the clamping table 300, and the end surface of the first end 2322a is pressed on the battery when the battery is clamped. The second end 2322b is connected with the connecting portion 2321, and the end surface of the second end 2322b is connected with the connecting portion 2321, and it can also be understood that the end surface of the second end 2322b is the cross section of the connecting portion 2321. Among them, the end surface area of the first end 2322a can be larger than the end surface area of the second end 2322b. It can be understood here that the pressing portion 2322 is a tapered or prismatic structure with one end large and the other end small.

[0054] In this scheme, the end surface of the first end 2322a is used to press the battery, so the end surface area of the first end 2322a is designed to be larger, thereby ensuring the reliability of the pressing. And the end surface area of the second end 2322b is designed to be smaller, so that the volume of the upper half of the pressure jaw 232 is smaller, so that the weight of the pressure jaw 232 is lighter. Therefore, this scheme not only ensures the reliability of the pressing, but also reduces the overall weight of the pressure jaw 232.

[0055] Of course, this application only discloses one possible structure of the pressure jaw 232, and the pressure jaw 232 can also have other structures, which are not limited herein.

[0056] In order to improve the welding efficiency of the battery, in another alternative, the pressure jaw 232 further includes an extension portion 2323, the extension portion 2323 can be arranged at the first end 2322a of the pressing portion 2322 and located on the side away from the connecting bracket 210. The extension portion 2323 can be provided with a welding hole 2323a, and the welding hole 2323a is arranged opposite to the clamping table 300. Here, it can be specifically understood that when the pressure jaw 232 and the clamping table 300 clamp the battery, the welding area of the battery is opposite to the welding hole 2323a, and the laser beam or the welding machine passes through the welding hole 2323a to weld the welding area. In this scheme, when welding each time, as long as the welding area of the battery is aligned with the welding hole 2323a, the precision and position of the battery do not need to be adjusted, thereby simplifying the positioning operation of the battery, and thus improving the welding efficiency of the battery.

[0057] In another alternative, the number of elastic buffers 220 can be multiple, and the number of clamping jaw bodies 230 can be multiple. The multiple clamping jaw bodies 230 are arranged side by side, and the multiple clamping jaw bodies 230 and the multiple elastic buffers 220 can be one-to-one corresponding. The multiple clamping jaw bodies 230 are arranged opposite to the clamping table 300. In this scheme, the multiple clamping jaw bodies and the clamping table 300 can form multiple clamping spaces side by side, thereby improving the clamping reliability of the battery. In addition, the multiple clamping jaw bodies 230 can clamp multiple batteries at the same time, thereby improving the processing efficiency. In addition, when the multiple clamping jaw bodies 230 and the clamping table 300 clamp a battery at the same time, the multiple clamping jaw bodies 230 can be clamped at different positions of the battery, and due to the existence of the elastic buffer 220, all the clamping jaw bodies 230 can reliably abut against the region, thereby further improving the reliability and safety of the clamp device.

[0058] In an alternative, as shown in FIG. 2, the number of elastic buffers 220 and the number of clamping jaw bodies 230 can both be two, and the two clamping jaw bodies 230 are arranged side by side. Of course, the number of elastic buffers 220 and the number of clamping jaw bodies 230 can also be other numbers, which are not limited herein. Figure 1

[0059] Of course, the number of guide rails 240 and the number of sliding blocks 250 correspond to the number of clamping jaw bodies 230, which are not described herein.

[0060] In another alternative, the connecting bracket 210 can include a first plate body 211 and a second plate body 212, and the first plate body 211 can be fixedly connected with the drive shaft of the first driving source 100. The second plate body 212 can be located on the side of the first plate body 211 away from the clamping table 300, and the first plate body 211 is perpendicular to the second plate body 212. The elastic buffer 220 and the clamping jaw body 230 can be located on the side of the first plate body 211 away from the first driving source 100. The clamping jaw body 230 can be connected with the second plate body 212 through the elastic buffer 220. In this scheme, the structure of the connecting bracket 210 is relatively simple, so as to reduce the manufacturing cost of the clamp device.

[0061] Optionally, in the case that the clamping member 200 includes the guide rail 240, the guide rail 240 is arranged on the surface of the side of the first plate body 211 away from the first driving source 100. Here, the guide rail 240 can be integrally formed with the first plate body 211, and of course the guide rail 240 can be connected with the first plate body 211 by welding, riveting, threaded connection, etc.

[0062] Of course, the connecting bracket 210 can also have other structures, which are not limited herein.

[0063] ​Based on the clamp device disclosed in the embodiments of the present application, the embodiments of the present application further disclose a battery production equipment, and the disclosed battery production equipment comprises the clamp device described in any of the above embodiments.

[0064] The battery production equipment in the present application further comprises an equipment rack, and the clamp device is mounted on the equipment rack. In one scheme, when the driving mechanism only comprises the first driving source 100, the first driving source 100 and the clamping table 300 can be arranged on the equipment rack of the battery production equipment. At this time, the equipment rack serves as the mounting basis of the components of the clamp device. Alternatively, in another optional scheme, the clamp device further comprises a clamp rack, at this time, the clamp rack serves as the mounting basis of other components of the clamp device, and the first driving source 100 and the clamping table 300 described above can be arranged on the clamp rack, and the clamp device is fixed on the equipment rack through the clamp rack. Meanwhile, when the driving mechanism comprises the first driving source 100 and the second driving source 600, the first driving source 100 and the second driving source 600 can be arranged on the equipment rack of the battery production equipment.
