DETAILED DESCRIPTION

[0035] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0036] The penetration welding device and the control method thereof of the present application will be described below. Figures 1-11

[0037] As shown in Figure 1 , Figure 2 and Figure 3 , the penetration welding device provided by the present application is used for penetration welding of a battery in a cup, and the penetration welding device comprises a turret 1, a clamping mechanism, a welding mechanism 3 and a removing mechanism.

[0038] ​The turret 1 includes a rotating mechanism 11 and an upper turntable 12 and a lower turntable 13 mounted on the rotating mechanism 11. The rotating mechanism 11 can be a rotating shaft and can rotate relative to the upper turntable 12 and the lower turntable 13. During the rotation of the rotating mechanism 11, the upper turntable 12 and the lower turntable 13 do not rotate. The upper turntable 12 is provided with an upper boss 121 that extends circumferentially along the upper turntable 12. The lower turntable 13 is provided with an inner boss 131 and an outer boss 132 coaxially arranged, both of which extend circumferentially along the lower turntable 13. The inner boss 131 is located inside the outer boss 132.

[0039] like Figure 3 As shown, the clamping mechanism includes a base 21, a clamping assembly 22, a lifting assembly 23, and a pressing assembly 24. The base 21 is connected to the rotating mechanism 11. The clamping assembly 22 is movably mounted on the base 21 in the vertical direction, and the bottom of the clamping assembly 22 abuts against the inner boss 131. The lifting assembly 23 is movably mounted on the base 21 in the vertical direction, and the bottom of the lifting assembly 23 abuts against the outer boss 132. The pressing assembly 24 is disposed opposite to the lifting assembly 23, movably mounted on the base 21 in the vertical direction, and the top of the pressing assembly 24 abuts against the upper boss 121. The bottom of the pressing assembly 24 abuts against the end of the battery, and a clearance position 2411 is formed at the bottom of the pressing assembly 24.

[0040] The connection between the base 21 and the rotating mechanism 11 can be by bolting, welding, or snap-fitting.

[0041] Since the base 21 is connected to the rotating mechanism 11, during the rotation of the rotating mechanism 11, the rotating mechanism 11 drives the pressing component 24, the clamping component 22 and the lifting component 23 to rotate. The pressing component 24 can slide on the upper boss 121, the clamping component 22 can slide on the inner boss 131, and the lifting component 23 can slide on the outer boss 132. Thus, the clamping component 22 can cooperate to clamp the battery, while the lifting component 23 is used to lift the battery, and the pressing component 24 presses the battery and drives the battery to rotate. Thus, the welding mechanism 3 can be used to complete the end welding of the battery.

[0042] Specifically, after the battery is capped, it is transferred to turret 1 in the penetration welding device. At this time, the lifting component 23 is lowered to a low position, the pressing component 24 is raised to a high position, and the clamping component 22 is raised to a high position to avoid the incoming material. After the battery is loaded, the clamping component 22 is lowered to a low position to clamp the battery, the lifting component 23 is raised to a high position to support the battery, and the pressing component 24 is lowered to a low position to press the battery down. Under the clamping of the clamping component 22 and the pressing of the pressing component 24 and the lifting component 23, the battery is fixed.

[0043] At this time, the bottom of the pressing assembly 24 abuts against the end of the battery, and the bottom of the pressing assembly 24 is formed with an avoiding position 2411 for avoiding at least part of the end of the battery, and the welding mechanism 3 welds the part of the end of the battery avoided by the avoiding position 2411.

[0044] As shown in Figure 1 , the rejecting mechanism is arranged on both sides of the turret 1, and is used for detecting the good and rejecting the defective before and after welding.

[0045] The penetrating welding device provided by the application comprises a turret 1, a clamping mechanism, and a welding mechanism 3. The clamping assembly 22 is movably arranged on the base 21 in the vertical direction and abuts against the inner boss 131 at the bottom, the jacking assembly 23 is movably arranged on the base 21 in the vertical direction and abuts against the outer boss 132 at the bottom, and the pressing assembly 24 is movably arranged on the base 21 in the vertical direction and abuts against the upper boss 121 at the top. Thus, during the rotation of the rotating mechanism 11 relative to the upper turntable 12 and the lower turntable 13, the clamping mechanism can clamp the battery, the jacking assembly 23 is used for jacking the battery, and the pressing mechanism is used for pressing the battery, so that the welding mechanism 3 can complete the welding of the battery, and the penetrating welding of the battery is automatically completed. Compared with the penetrating welding device of the prior art, on the one hand, the chain transmission structure is improved to the turret 1 type transmission structure by arranging the turret 1, so that the overall size is reduced and the welding efficiency is improved; on the other hand, the rejecting mechanism is arranged on both sides of the turret 1, so that the good and the defective before and after welding are detected and rejected, and the welding quality is ensured.

[0046] In one embodiment, as shown in Figure 1 , the rejecting mechanism comprises a first rejecting unit 41 and a second rejecting unit 42. The first rejecting unit 41 is arranged on one side of the welding mechanism 3 and is used for detecting the height of the battery before welding and rejecting the defective battery. The second rejecting unit 42 is arranged on the other side of the welding mechanism 3 and is used for detecting the welding quality of the battery after welding and rejecting the defective battery.

[0047] Specifically, the first rejecting unit 41 comprises a height detector, and is arranged between the feeding chain plate 5 and the turret 1, and is used for detecting the height of the battery to be fed into the turret 1. The battery meeting the height requirement is fed into the turret 1, and the battery not meeting the requirement is rejected. The second rejecting unit 42 comprises an image acquisition and recognition device and a pushing mechanism, and is arranged at the discharge port of the turret 1. The image recognition device is used for recognizing the welding quality of the battery after welding. The good battery meeting the welding requirement is pushed into the good output chain plate 8, and the defective battery not meeting the welding requirement is pushed into the defective output chain plate 9 by the pushing mechanism.

[0048] The pushing mechanism is fixed on the table top of the machine table 10, and the output end of the pushing mechanism is used for pushing the substandard battery.

[0049] Further, as shown in Figure 1 the penetrating welding device further comprises a rejection turntable, an input turntable 6, and an output turntable 7. The input turntable 6 is arranged at the outlet of the input chain plate 5 and is used for pushing the incoming material of the input chain plate 5 into the turret 1. The output turntable 7 is arranged at the outlet of the turret 1 and is used for pushing the outgoing material of the turret 1 out. The rejection turntable is arranged on one side of the output turntable 7, and the battery pushed out by the output turntable 7 enters the rejection turntable. The second rejection unit 42 is arranged above the rejection turntable. The good battery is pushed into the good output chain plate 8 by the rejection turntable, and the substandard battery is pushed into the substandard output chain plate 9 by the second rejection unit 42.

[0050] It can be understood that the rejection mechanism can not only reject substandard products, but also can be applied to classify different models of batteries and is suitable for application in various scenes.

[0051] Specifically, the cup and the battery are first fed from the battery incoming chain plate, and then rotated by the input turntable 6 to rotate the cup and the battery to the carrying plate of the turret 1, and then wait for the clamping mechanism to hold.

[0052] After the welding is completed, the cup and the battery are released by the clamping mechanism, and then the cup and the battery are output to the rejection turntable by the output turntable 7. The second rejection unit 42 and the rejection turntable sort the battery to the good output chain plate 8 or the substandard output chain plate 9.

[0053] Based on the above embodiment, in one embodiment, as shown in Figure 4 the lower pressing assembly 24 comprises a mounting seat 242, a pressing head 241, and a cam assembly 243. The mounting seat 242 is movably connected with the base 21 in the vertical direction, the mounting seat 242 is arranged on the upper boss 121 through the cam assembly 243, the mounting seat 242 is connected with the pressing head 241, and the pressing head 241 is coaxially arranged with the jacking assembly 23. The pressing head 241 is used for abutting against the end of the battery, and at least part of the end of the battery is avoided when the pressing head 241 abuts against the end of the battery.

[0054] Specifically, the mounting seat 242 is movably connected with the base 21 in the vertical direction, and the cam assembly 243 is arranged on the mounting seat 242. When the rotating mechanism 11 rotates, the cam assembly 243 moves on the upper boss 121, and the mounting seat 242 also moves. The pressing head 241 is a copper pressing head 241. When the cam assembly 243 moves on the upper boss 121, the mounting seat 242 is driven to move, and the copper pressing head 241 is also driven to move up and down. The copper pressing head 241 is provided with an avoiding hole. When the pressing head 241 abuts against the end of the battery, at least part of the end of the battery is avoided, so that the penetrating welding mechanism 3 can perform penetrating welding on the avoided part of the end of the battery.

[0055] In one embodiment, as shown in Figure 5 and Figure 6 The jacking assembly 23 comprises a jacking piece 232, a second roller 233 and a carrier 231. One end of the jacking piece 232 is connected to the carrier 231 for carrying the battery, and the bottom end of the jacking piece 232 is arranged on the outer boss 132 through the second roller 233.

[0056] The jacking piece 232 comprises a sleeve rod 2321, a jacking rod 2322 and an elastic piece 2323. One end of the sleeve rod 2321 is connected to the carrier 231 for carrying the battery, the sleeve rod 2321 is provided with the elastic piece 2323, the other end of the sleeve rod 2321 is connected with the elastic piece 2323, the elastic piece 2323 is connected with the top end of the jacking rod 2322, and the bottom end of the jacking rod 2322 is arranged on the outer boss 132 through the second roller 233.

[0057] Specifically, the top end of the sleeve rod 2321 is connected with an inner support rod, the inner support rod is provided with the carrier 231 for directly carrying the battery, the sleeve rod 2321 is provided with the elastic piece 2323, the elastic piece 2323 can be a spring, and the bottom end of the sleeve rod 2321 is arranged on the outer boss 132 through the elastic piece 2323, the jacking rod 2322 and the second roller 233. During the rotation of the rotating mechanism 11, the second roller 233 can move on the outer boss 132, and the elastic piece 2323 can provide a certain floating space for the entire jacking assembly 23, so that the battery can be prevented from being damaged by pressure when being lifted.

[0058] In order to adjust the length of the entire jacking assembly 23, the inner support rod is slidably arranged in the sleeve rod 2321, the inner support rod is connected with the carrier 231, the sleeve rod 2321 is provided with a limiting groove, and the inner support rod is provided with a sliding block extending out of the limiting groove. By moving the sliding block, the relative position between the inner support rod and the sleeve rod 2321 can be adjusted, so that the length of the jacking assembly 23 can be adjusted.

[0059] Based on the above embodiment, in one embodiment, as shown in Figure 7 The clamping assembly 22 comprises a clamp 221, a support rod 222 and a first roller 223. One end of the clamp 221 is provided with two clamping pieces arranged at intervals, the two clamping pieces are arranged on both sides of the axis of the jacking assembly 23, the two clamping pieces are both provided with a profiling groove for abutting against the outer wall of the battery, and the other end of the clamp 221 is arranged on the inner boss 131 through the support rod 222 and the first roller 223.

[0060] In the embodiment, the two clamping members are provided with profiling grooves for abutting against the outer wall of the battery. Thus, when the battery is clamped, the contact area between the inner wall of the clamping member and the outer wall of the battery is increased, thereby ensuring the stability of clamping. The other end of the clamp 221 is connected to the support rod 222, and the bottom of the support rod 222 is provided with a first roller 223, so that the first roller 223 can move on the inner boss 131 during the rotation of the rotating mechanism 11.

[0061] In some embodiments, the profiling grooves are provided with a buffer layer towards the inner wall of the battery, so as to play a buffering role when the battery is clamped, preventing damage to the battery.

[0062] In the process of clamping the battery by using the clamping assembly 22, the first roller 223 of the clamping assembly 22 moves on the inner boss 131, and when the first roller 223 moves to the low position, the clamp 221 moves downward, and the profiling grooves on the clamp 221 clamp the battery. When the first roller 223 moves to the high position, the clamp 221 moves upward, so that the clamp 221 is separated from the battery.

[0063] In addition, the two clamping members on the clamp 221 are a first clamping member and a second clamping member, and the first clamping member and the second clamping member are arranged on the connecting plate through corresponding rotating shafts. The first clamping member and the second clamping member can rotate relative to the connecting plate. At the same time, the first clamping member is hinged with a first guide rod, the second clamping member is hinged with a second guide rod, the first clamping member is connected to the support rod 222 through the first guide rod, the second clamping member is connected to the support rod 222 through the second guide rod, and a spring is connected with the first clamping member and the second guide rod.

[0064] In the process of clamping the battery by using the clamping assembly 22, the first roller 223 of the clamping assembly 22 moves on the inner boss 131, and when the first roller 223 moves to the low position, the clamp 221 moves downward, and the first clamping member is pulled by the support rod 222 through the first guide rod, and the second clamping member is pulled by the support rod 222 through the second guide rod. At this time, the first guide rod and the second guide rod rotate relative to the support rod 222, and in the process of rotating the first guide rod and the second guide rod relative to the support rod 222, the spring rotates relative to the support rod 222. When the spring rotates to an acute angle with the support rod 222, the spring pulls the first clamping member and the second clamping member to close to each other, and the two clamping members clamp the battery. After the clamp 221 moves upward, the first guide rod and the second guide rod rotate relative to the support rod 222, and the spring rotates relative to the support rod 222. When the spring rotates to a perpendicular or other angle with the support rod 222, the spring pulls the first clamping member and the second clamping member apart, and at this time, the two clamping members are opened, so that the inner wall of the clamping member is separated from the battery, thereby realizing the clamping and loosening of the battery, and effectively ensuring the stability of the battery during sealing and welding.

[0065] In order to guide the movement of the clamping assembly 22, the second side of the base 21 is provided with a guide rail arranged in the vertical direction, and the support rod 222 is slidably arranged on the guide rail. By arranging the vertically extending guide rail, the vertical movement of the clamping assembly 22 can be ensured.

[0066] Similarly, a guide rail for the pressing assembly 24 can also be arranged on the base 21, and by arranging the vertically extending guide rail, the vertical movement of the pressing assembly 24 can be ensured.

[0067] In an embodiment, as shown in Figure 2 the first protrusion and the second protrusion are arranged on the inner boss 131, the height of the first protrusion is greater than the height of the second protrusion, the third protrusion and the fourth protrusion are arranged on the outer boss 132, the height of the third protrusion is greater than the height of the fourth protrusion, and the fifth protrusion and the sixth protrusion are arranged on the upper boss 121, the height of the fifth protrusion is greater than the height of the sixth protrusion.

[0068] During the welding process of the welding mechanism 3, the clamping assembly 22 moves to the second protrusion to clamp the battery, the jacking assembly 23 moves to the third protrusion to lift the battery, and the pressing assembly 24 moves to the sixth protrusion to press the battery; during the non-welding process of the welding mechanism 3, the clamping assembly 22 moves to the first protrusion to release the battery, the jacking assembly 23 moves to the fourth protrusion to lower the battery, and the pressing assembly 24 moves to the fifth protrusion to move away from the battery.

[0069] Specifically, after the battery is transferred to the clamping mechanism, the jacking assembly 23 moves to the fourth protrusion to be in a low position, the pressing assembly 24 moves to the fifth protrusion to be in a high position, and the clamping assembly 22 moves to the first protrusion to be in a high position to avoid the incoming material. When the battery feeding is completed, the clamping assembly 22 moves to the second protrusion to be in a low position, the clamping assembly 22 is lowered to clamp the battery, the jacking assembly 23 moves to the third protrusion to rise to a high position, the jacking assembly 23 lifts the battery, and the pressing assembly 24 moves to the sixth protrusion to a low position to press the battery. The battery is fixed under the clamping of the clamping assembly 22 and the pressing of the pressing assembly 24 and the jacking assembly 23. At this time, the bottom of the pressing assembly 24 abuts against the end of the battery, and the bottom of the pressing assembly 24 forms an avoiding position 2411; the welding mechanism 3 welds the end of the battery avoided by the avoiding position 2411.

[0070] In order to improve the welding efficiency of the penetration welding device, as shown in Figure 1 a plurality of clamping mechanisms are arranged, and each clamping mechanism is arranged in sequence along the rotation direction of the turret 1. The pressing assembly 24 in each clamping mechanism is arranged on the upper boss 121, the clamping assembly 22 in each clamping mechanism is arranged on the inner boss 131, and the jacking assembly 23 in each clamping mechanism is arranged on the outer boss 132.

[0071] When only one welding mechanism 3 is provided, when the clamping mechanism of the first station is aligned with the welding mechanism 3, the corresponding clamping assembly 22 moves to the second protrusion to clamp the battery, the jacking assembly 23 moves to the third protrusion to lift the battery, and the pressing assembly 24 moves to the sixth protrusion to press the battery. At this time, the welding mechanism 3 is used to weld the end of the battery. During welding, the rotating mechanism 11 stops rotating. While the clamping assembly 22 in the other clamping mechanism moves to the first protrusion to release the battery, the jacking assembly 23 moves to the fourth protrusion to lower the battery, and the pressing assembly 24 moves to the fifth protrusion to move away from the battery. After the first station completes welding, the rotating mechanism 11 continues to rotate, and the clamping mechanism of the second station is aligned with the welding mechanism 3, so that the welding mechanism 3 can weld the battery of the second station. Repeat the above steps to weld all the batteries on the clamping mechanism.

[0072] As shown in Figure 3 , the base 21 is a bearing structure of the pressing assembly 24, the clamping assembly 22 and the jacking assembly 23. The first side of the base 21 is connected with the rotating mechanism 11. The second side opposite to the first side of the base 21 is provided with the pressing assembly 24, the clamping assembly 22 and the jacking assembly 23 which are slidable relative to the base 21. The central axis of the jacking assembly 23 coincides with the central axis of the pressing assembly 24. The clamping central axis of the clamping assembly 22 is parallel to the central axis of the jacking assembly 23. Since the base 21 is connected with the rotating mechanism 11, during the rotation of the rotating mechanism 11, the rotating mechanism 11 drives the pressing assembly 24, the clamping assembly 22 and the jacking assembly 23 to rotate. The pressing assembly 24 is slidable on the upper boss 121. The clamping assembly 22 is slidable on the inner boss 131. The jacking assembly 23 is slidable on the outer boss 132. Thus, the clamping assembly 22 can clamp the battery, the jacking assembly 23 can lift the battery, and the pressing assembly 24 can press the battery, so that the welding mechanism 3 can weld the end of the battery.

[0073] In addition, the penetration welding device further comprises a support plate and a cup. The support plate is connected to the base 21. The support plate is provided with a first through hole. As shown in Figure 4 , the support plate is further provided with a corner guard. The corner guard is used to limit the cup as shown in Figure 8 , so that the battery can be coaxial with the pressing assembly 24 and the jacking assembly 23. The support plate is connected to the base 21. The corner guard is arranged on the support plate and located on both sides of the central axis of the jacking assembly 23. The corner guard is matched with the shape of the cup and is used to limit and fix the position of the cup. The bottom of the cup is provided with a second through hole. The first through hole and the second through hole are coaxially arranged. The second driven wheel can pass through the first through hole and the second through hole in sequence through the lifting of the jacking rod 2322 to lift the battery in the cup.

[0074] In addition, in order to make the battery more precisely welded during the sealing process, the cup and the angle can be made to be more closely fitted, and in the embodiment, the peripheral wall of the angle can be provided with a magnet sheet, and the outer wall of the cup can be provided with a material capable of being attracted by the magnet sheet, such as iron, nickel, cobalt, or other metal or alloy materials. Conversely, the magnet sheet can also be provided on the cup, which will not be described here.

[0075] Specifically, after the battery is capped, the battery is transferred to the penetration welding device through the feeding chain plate 5 and the feeding turntable 6. The rotating mechanism 11 rotates, and the rotating mechanism 11 drives the pressing assembly 24, the clamping assembly 22, and the lifting assembly 23 to rotate. The second roller 233 moves on the outer boss 132, and after the second roller 233 moves to the high position, the inner support rod lifts the battery on the second driven roller. At the same time, the first roller 223 of the clamping assembly 22 moves on the inner boss 131, and when the first roller 223 moves to the low position, the clamp 221 moves downward, and the plurality of first driven rollers on the clamp 221 clamp the battery. At this time, the cam assembly 243 on the pressing assembly 24 rotates to the low position, and the pressing head 241 is pressed downward, and the battery is between the pressing head 241 and the second driven roller. At this time, the elastic member 2323 is in a compressed state, and the elastic member 2323 can provide a certain floating space for the entire lifting assembly 23.

[0076] The welding mechanism 3 controls the welding of the end of the battery. After the welding is completed, the rotating mechanism 11 continues to rotate, and the second roller 233 moves on the outer boss 132. After the second roller 233 moves to the low position, the inner support rod lowers the battery on the second driven roller. At the same time, the first roller 223 of the clamping assembly 22 moves on the inner boss 131, and when the first roller 223 moves to the high position, the clamp 221 moves upward, so that the clamp 221 is separated from the battery. The cam assembly 243 on the pressing assembly 24 rotates to the high position, and the pressing head 241 also moves upward. At this time, the elastic member 2323 is in a natural state, and then the battery can be moved to the next station, thereby completing the penetration welding of the battery.

[0077] After the penetration welding is completed, the battery is transferred to the rejection turntable through the output turntable 7. The second rejection unit 42 detects the welding quality of the battery. The good products are transferred to the good product output chain plate 8 by the rejection turntable, and the defective products are transferred to the defective product output chain plate 9 by the second rejection unit 42.

[0078] Further, as shown in Figure 9 The present application also provides a control method of the penetration welding device based on any one of the above embodiments, comprising steps 910 to 960.

[0079] Step 910, obtaining a target height threshold and actual height information of the battery.

[0080] In this step, the target height threshold value can be the good product height range of the battery, or the height range of a specific model of battery.

[0081] The controller detects the actual height of the passing battery through the first rejection unit 41.

[0082] Step 920, based on the actual height information and the target height threshold value, the first rejection unit 41 is controlled to reject the first defective battery, and the first good product battery is sent into the turret 1.

[0083] In this step, the controller compares the actual height information of the battery with the target height threshold value, and the battery that meets the target height threshold value is the first good product battery, and the battery that does not meet the target height threshold value is the first defective battery.

[0084] Step 930, control the welding mechanism 3 to perform penetration welding on the first good product battery.

[0085] In this step, the clamping mechanism is driven by the rotating mechanism 11 to bring the first good product battery to the welding station, and the welding mechanism 3 performs penetration welding on the end of the first good product battery.

[0086] Step 940, control the clamping mechanism to send the welded first good product battery out of the turret 1.

[0087] In this step, the first good product battery after welding is sent out of the turret 1, and the first good product battery enters the rejection turntable.

[0088] Step 950, get the actual welding picture of the first good product battery after welding.

[0089] In this step, the actual welding picture is the end picture of the first good product battery after welding obtained by the second rejection unit 42, and the actual welding picture includes the welding position of the first good product battery.

[0090] Step 960, based on the actual welding picture, control the second rejection unit 42 to reject the second defective battery, and send the second good product battery into the next station.

[0091] In this step, the controller compares the actual welding picture with the target welding image, or directly detects the actual welding picture intelligently to identify the welding quality of the end of the first good product battery, and the first good product battery that meets the welding requirement is the second good product battery, and the first good product battery that does not meet the welding requirement is the second defective battery.
