Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a battery positioning and processing device. Background Technology

[0002] The electrification of new vehicles has become the mainstream trend in the global automotive industry, leading to a continuous increase in demand for power batteries and a sustained expansion of the global lithium-ion battery market. Battery sealing nail welding equipment includes loading, laser cleaning, nailing, pre-welding, final welding, post-weld inspection, and unloading stations. All these stations, from cleaning and nailing to welding and inspection, require precise battery positioning. However, existing sealing nail welding equipment, whether rotary or linear, requires fixtures to move the battery between stations. When the fixture moves from one station to the next, the battery within it needs to be repositioned, resulting in repetitive positioning, high costs, difficulty in improving efficiency, and high failure rates. Summary of the Invention

[0003] Based on this, and in view of the technical problems existing in the prior art, the purpose of the present invention is to provide a battery positioning and processing device.

[0005] The present invention provides a battery positioning processing device, which includes a positioning fixture and a pre-pressing mechanism; the positioning fixture is provided with a plurality of positioning slots for placing batteries, each positioning slot has an elastic element at its bottom and a clamping element on the positioning fixture for clamping the batteries in each positioning slot; the pre-pressing mechanism is used to apply pressure to the batteries in each positioning slot to compress the elastic element, and when the elastic element is compressed, the clamping element clamps the battery.

[0006] This invention, by setting up an elastic element, a clamping element, and a pre-compression mechanism, allows the battery to be loaded into the positioning groove. The pre-compression mechanism applies pressure to the battery to compress the elastic element, thereby adjusting the battery height. Then, the clamping element clamps the battery, thus completing the battery positioning. After positioning, the battery position does not need to be adjusted again. Positioning only needs to be done once to meet the processing positioning accuracy. It has the advantages of simple positioning, high positional accuracy consistency, no need for repeated positioning, simplified mechanism design, and low cost, thereby improving the efficiency of battery processing and reducing the cost of design, debugging, and maintenance.

[0007] As a further improvement to the above-described solution of the present invention, the battery positioning and processing device further includes a conveying mechanism and an adjusting mechanism; wherein:

[0008] The conveying mechanism transports the positioning fixture along a predetermined direction. Along the conveying direction of the conveying mechanism, there are sequentially arranged a battery loading station, a pre-pressing station, several processing stations, and a battery unloading station; the pre-pressing mechanism is installed at the pre-pressing station.

[0009] The adjustment mechanism includes adjustment component one, adjustment component two, and adjustment component three. Adjustment component one, adjustment component two, and adjustment component three are respectively installed at the battery loading station, the pre-pressing station, and the battery unloading station. When the positioning fixture moves to the loading station, adjustment component one releases the clamping force of the clamping component to load the battery into the positioning slot. When the positioning fixture moves to the pre-pressing station, adjustment component two releases the clamping force of the clamping component to pre-press the battery in the pre-pressing mechanism. When the elastic component is compressed, the clamping component clamps the battery. When the positioning fixture moves to the battery unloading station, adjustment component three releases the clamping force of the clamping component to unload the battery.

The other side of the end clamp plate is connected to an end rod, which slides through the battery fixture. A spring is installed on one end of the end rod in the positioning groove, and the two ends of the spring are connected to the end clamp plate and the battery fixture, respectively. In the natural state, the side clamp plate and the end clamp plate can clamp the battery. Adjusting parts one, two, and three are used to apply pressure to the side rod and the end rod to increase the distance between the side clamp plate and the end clamp plate and the battery, thereby releasing the clamping force of the clamping parts.

[0014] As a further improvement of the above-mentioned solution of the present invention, the positioning fixture is provided with an open top opening, and a vertically arranged partition is fixed inside the opening. The partition divides the opening into two positioning slots, and an insulating plate is installed on both sides of the partition. The side clamps in the two positioning slots are arranged parallel to and opposite to the partition, and the space between the side clamps, end clamps, and partition is used to place the battery.

[0015] As a further improvement to the above-mentioned solution of the present invention, the clamping member further includes two connecting plates and a movable plate disposed outside the positioning fixture.

The connecting plates are connected to the side rods. A vertically arranged connecting shaft is installed on the connecting plate and a roller is rotatably mounted on the connecting shaft. A sliding plate is disposed between the connecting plate and the positioning fixture. The sliding plate is inclined and both ends of the sliding plate are slidably connected to the positioning fixture through sliders. A straight plate is connected to one end of the sliding plate. The distance between the end of the sliding plate away from the straight plate and the connecting plate is less than the distance between the end of the sliding plate closer to the straight plate and the connecting plate. The sliding plate is always rolling and in close contact with the roller. The movable plate is perpendicular to the partition plate. The movable plate is connected to each end rod and the end of the two straight plates away from the sliding plate is connected.

[0022] This invention, by setting up an elastic element, a clamping element, and a pre-compression mechanism, allows the battery to be loaded into the positioning groove. The pre-compression mechanism applies pressure to the battery to compress the elastic element, thereby adjusting the battery height. Then, the clamping element clamps the battery, thus completing the battery positioning. After positioning, the battery position does not need to be adjusted again. Positioning only needs to be done once to meet the processing positioning accuracy. It has the advantages of simple positioning, high positional accuracy consistency, no need for repeated positioning, simplified mechanism design, and low cost, thereby improving the efficiency of battery processing and reducing the cost of design, debugging, and maintenance.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Please refer to Figures 1-3 This embodiment proposes a battery positioning processing device, including a positioning fixture 100, a pre-pressing mechanism 200, and may also include a conveying mechanism 400 and an adjustment mechanism.

[0037] The conveying mechanism 400 includes a turntable 410 and a drive motor 420 for rotating the turntable 410. Along the rotation direction of the turntable 410, a battery loading station, a pre-pressing station, and a battery unloading station are arranged sequentially. A battery loading robot (not shown) is installed at the battery loading station, a pre-pressing mechanism 200 is installed at the pre-pressing station, and a battery unloading robot (not shown) is installed at the battery unloading station. Several processing stations are also arranged between the pre-pressing station and the battery unloading station. For example, according to the processing steps, a laser cleaning station, a nailing station, a pre-welding station, a final welding station, and a post-welding inspection station are arranged sequentially between the pre-pressing station and the battery unloading station. Corresponding laser cleaning equipment, nailing equipment, pre-welding equipment, final welding equipment, and post-welding inspection equipment can be installed at the laser cleaning station, nailing station, pre-welding station, final welding station, and post-welding inspection station, respectively.

[0038] The positioning fixture 100 is used to position and clamp the battery 300. In this embodiment, the positioning fixture 100 is mounted on the turntable 410 and can rotate with the turntable 410. Multiple positioning fixtures 100 can be provided, and they are evenly distributed circumferentially on the top surface of the turntable 410. This allows multiple batteries 300 to be processed simultaneously, improving work efficiency. Please refer to... Figures 4-6 The positioning fixture 100 has an open top opening, inside which a vertically arranged partition 140 is fixed. The partition 140 divides the opening into two positioning slots 110 for placing batteries 300. The loading robot loads two batteries 300 to be processed into the two positioning slots 110 at a time. To ensure safety, insulating plates 141 are installed on both sides of the partition 140. The positioning fixture 100 is equipped with clamping members 130 for clamping the batteries 300 in the two positioning slots 110.

[0039] The clamping component 130 includes two side clamping plates 131, two end clamping plates 132, two connecting plates 139, and a moving plate 1311. The two side clamping plates 131 are respectively disposed in two positioning grooves 110 and are parallel to the partition 140. The side of the side clamping plate 131 facing the partition 140 is the clamping surface and an insulating plate 133 is installed on the clamping surface. The other side of the side clamping plate 131 is connected to a side rod 134, which slides through the battery 300 fixture. A spring 135 is fitted on a section of the side rod 134 located in the positioning groove 110, and the two ends of the spring 135 are respectively connected to the side clamping plate 131 and the battery 300 fixture. Two end clamps 132 are respectively disposed in two positioning slots 110. The end clamps 132 and side clamps 131 in the same positioning slot 110 are arranged in an L-shape. The side of the end clamp 132 near the side clamp 131 is a clamping surface and an insulating plate 136 is installed on the clamping surface. The other side of the end clamp 132 is connected to an end rod 137, which slides through the battery 300 fixture. A spring 138 is fitted on a section of the end rod 137 in the positioning slot 110, and the two ends of the spring 138 are respectively connected to the end clamp 132 and the battery 300 fixture. An insulating plate 150 is installed on the inner wall of the positioning slot 110 opposite to the end clamp 132. The side clamps 131, end clamps 132, and partition 140 in the positioning slot 110 form an area for placing the battery 300. Two connecting plates 139 are respectively disposed on opposite sides of the positioning fixture 100, and both connecting plates 139 are parallel to the partition plate 140. The side rods 134 connected to the two side clamping plates 131 are located outside the positioning fixture 100 and are respectively connected to the two connecting plates 139. A vertically arranged connecting shaft 1312 is installed on the connecting plate 139, and a roller 1313 is rotatably installed on the connecting shaft 1312. A sliding plate 1310 is provided between the connecting plate 139 and the positioning fixture 100. The sliding plate 1310 is arranged at an angle, and both ends of the sliding plate 1310 are slidably connected to the positioning fixture 100 through sliders 1315. A straight plate 1314 is connected to one end of the sliding plate 1310. The distance between the end of the sliding plate 1310 away from the straight plate 1314 and the connecting plate 139 is less than the distance between the end of the sliding plate 1310 closer to the straight plate 1314 and the connecting plate 139. The sliding plate 1310 is always rolling and in contact with the roller 1313. The movable plate 1311 is located at one end of the positioning fixture 100 and is perpendicular to the partition plate 140. The end rods 137 connected to the two end clamps 132 are located outside the positioning fixture 100 and are connected to the movable plate 1311. The movable plate 1311 is connected to the ends of the two straight plates 1314 away from the sliding plate 1310. Two L-shaped plates 1316 arranged vertically opposite each other are installed on the side of the movable plate 1311 away from the positioning fixture 100, and a groove is formed between the two L-shaped plates 1316.When the movable plate 1311 is moved away from the positioning fixture 100, the movable plate 1311 directly pulls the two end clamps 132 to move and compress the third spring 138 via the end rod 137. The movable plate 1311 also pulls the two sliding plates 1310 to move via the two straight plates 1314. Because the sliding plates 1310 are tilted and always in contact with the rollers 1313, the sliding plates 1310 will press the connecting plate 139 outward when they move. The connecting plate 139 then pulls the side clamps 131 to move and compress the second spring 135 via the side rod 134, thereby... As the area between the side clamping plate 131 and the end clamping plate 132 increases, the loading robot loads the battery 300 into the positioning slot 110 and then releases the moving plate 1311. Under the action of the second spring 135 and the third spring 138, the side clamping plate 131 and the end clamping plate 132 can reset and clamp the battery 300. When it is necessary to remove the battery 300, the moving plate 1311 is moved away from the positioning fixture 100 so that the side clamping plate 131 and the end clamping plate 132 release the battery 300, and the unloading robot can remove the battery 300.

[0040] Due to processing requirements, the height of the battery 300 within the positioning groove 110 may need to be adjusted. In this embodiment, elastic elements 120 are installed at the bottom of both positioning grooves 110. After the battery 300 enters the positioning groove 110, the elastic elements 120 will be compressed to a certain extent under the gravity of the battery 300. When the positioning fixture 100 moves to the pre-pressing station, the moving plate 1311 is moved away from the positioning fixture 100 so that the side clamping plate 131 and the end clamping plate 132 release the battery 300. The pre-pressing mechanism 200 applies pressure to the battery 300 in the two positioning grooves 110 to further compress the elastic elements 120. When the height of the battery 300 reaches the predetermined height, the moving plate 1311 is released. Under the action of the second spring 135 and the third spring 138, the side clamping plate 131 and the end clamping plate 132 can reset and just clamp the battery 300. At this time, the height of the battery 300 meets the processing requirements.

[0041] In this embodiment, the elastic element 120 includes multiple springs 121, a base plate 122, and multiple guide rods (not shown). The multiple springs 121 are all installed at the bottom of the positioning groove 110. The base plate 122 is positioned above the multiple springs 121 and its bottom is connected to the multiple springs 121. An insulating plate (not shown) is installed on the top surface of the base plate 122. The multiple guide rods are respectively disposed within the multiple springs 121, with their top ends connected to the base plate 122 and their bottom ends slidably connected to the positioning fixture 100. After the battery 300 enters the positioning groove 110, it is directly supported by the base plate 122. The battery 300 will compress the base plate 122, causing the springs 121 to compress.

[0042] In this embodiment, please refer to Figure 7The pre-compression mechanism 200 includes a mounting plate 210, a cylinder 220, and a pre-compression plate 230. The mounting plate 210 is vertically arranged and installed on the ground or an external equipment mounting frame. A vertically arranged guide rail 240 is mounted on the side of the mounting plate 210 near the turntable 410. The pre-compression plate 230 is horizontally arranged, with one end slidably connected to the guide rail 240. A pre-compression block 250 is mounted on the bottom of the pre-compression plate 230. The cylinder 220 is mounted on the mounting plate 210, and its telescopic end is connected to the pre-compression plate 230. When the positioning fixture 100 moves to the pre-compression station, the cylinder 220 drives the pre-compression plate 230 to move downwards. The pre-compression block 250 follows the pre-compression plate 230 downwards, contacting the top of the battery 300 and pre-compressing the battery 300.

[0043] To facilitate the movement of the movable plate 1311, this embodiment is provided with an adjustment mechanism, which includes an adjustment component 1 510, an adjustment component 2 520, and an adjustment component 3 530. The adjustment components 1 510, 2 520, and 3 530 are respectively installed at the battery loading station, the pre-pressing station, and the battery unloading station. The adjustment components 1 510, 2 520, and 3 530 are all used to pull the movable plate 1311 to move away from the positioning fixture 100.

[0044] Combination Figure 8 The adjusting component 510 includes a cylinder 511, with a locking block 512 connected to the telescopic end of the cylinder 511. The cylinder 511 is always extended. As the positioning fixture 100 moves to the loading station following the turntable 410, the locking block 512 can precisely engage with the slots formed by the two L-shaped plates 1316 on the outer side of the moving plate 1311. Then, the cylinder 511 retracts, pulling the moving plate 1311 away from the positioning fixture 100, thus increasing the area between the side clamping plate 131 and the end clamping plate 132. This allows the loading robot to load the two batteries 300 into the two positioning slots 110 respectively. After the batteries 300 enter the positioning slots 110, the cylinder 511 extends, causing the moving plate 1311 to reset. The side clamping plate 131 and the end clamping plate 132 reset under the action of springs 135 and 138 respectively, thus clamping the batteries 300 again. Then the turntable 410 rotates, causing the positioning fixture 100 to rotate. During the rotation, the locking block 512 automatically disengages from the two L-shaped plates 1316.

[0045] Combined Figure 7Adjustment component 2 520 includes cylinder 2 521, which is mounted on mounting plate 210. A locking block 2 522 is connected to the telescopic end of cylinder 2 521. Cylinder 2 521 is always extended. During the process of positioning fixture 100 rotating and moving with turntable 410 to the pre-pressing station, locking block 2 522 can just fit into the slots formed by the two L-shaped plates 1316 on the outer side of moving plate 1311. Then, cylinder 2 521 retracts, pulling moving plate 1311 away from positioning fixture 100, so that side clamping plate 131 and end clamping plate 132 release battery 300. Cylinder 4 220 drives pre-pressing plate 230 to move downwards, compressing battery 300 to compress spring 1 121, thereby adjusting the height of battery 300. Once the battery 300 reaches the predetermined height, cylinder 2 521 extends, causing the moving plate 1311 to reset. The side clamping plate 131 and end clamping plate 132 reset under the action of spring 2 135 and spring 3 138 respectively, thus clamping the battery 300 again. Then, the turntable 410 rotates, causing the positioning fixture 100 to rotate. During the rotation, the locking block 2 522 automatically disengages from the two L-shaped plates 1316.

[0046] Combination Figure 9 The adjusting component 530 includes a cylinder 531, with a locking block 532 connected to the telescopic end of the cylinder 531. The cylinder 531 is always extended. During the process of the positioning fixture 100 rotating and moving to the pre-pressing station with the turntable 410, the locking block 532 can just fit into the slots formed by the two L-shaped plates 1316 on the outer side of the moving plate 1311. Then, the cylinder 531 retracts, pulling the moving plate 1311 away from the positioning fixture 100, so that the side clamping plate 131 and end clamping plate 132 release the battery 300, allowing the unloading robot to remove the battery 300. After the battery 300 is removed, the cylinder 531 extends, causing the moving plate 1311 to reset, and the side clamping plate 131 and end clamping plate 132 reset under the action of springs 135 and 138, respectively. Then the turntable 410 rotates, causing the positioning fixture 100 to rotate. During the rotation, the three-piece card block 532 automatically disengages from the two L-shaped plates 1316.

[0047] Next, the working principle of this embodiment will be explained.

[0048] In the initial state, cylinder 1 511, cylinder 2 521, and cylinder 3 531 are in the extended state, and drive motor 420 starts to drive turntable 410 to rotate intermittently;

[0049] The positioning fixture 100 moves to the loading station following the rotation of the turntable 410. The first clamping block 512 fits perfectly into the slots formed by the two L-shaped plates 1316 on the outer side of the moving plate 1311. Then, the first cylinder 511 retracts, pulling the moving plate 1311 away from the positioning fixture 100, thus increasing the area between the side clamping plate 131 and the end clamping plate 132. This allows the loading robot to load two batteries 300 into the two positioning slots 110 respectively. After the batteries 300 enter the positioning slots 110, the first cylinder 511 extends, causing the moving plate 1311 to reset. The side clamping plate 131 and the end clamping plate 132 reset under the action of the second spring 135 and the third spring 138, respectively, and clamp the batteries 300 again. Then, the turntable 410 rotates, causing the positioning fixture 100 to rotate. During this rotation, the first clamping block 512 automatically disengages from the two L-shaped plates 1316.

[0050] The positioning fixture 100 moves to the pre-pressing station as the turntable 410 rotates. The second clamping block 522 can just fit into the slot formed by the two L-shaped plates 1316 on the outer side of the moving plate 1311. Then, the second cylinder 521 retracts and pulls the moving plate 1311 away from the positioning fixture 100, so that the side clamping plate 131 and the end clamping plate 132 release the battery 300. The fourth cylinder 220 drives the pre-pressing plate 230 to move downward and squeeze the battery 300 so that the first spring 121 is compressed, thereby adjusting the height of the battery 300. When the height of the battery 300 reaches the predetermined height, the second cylinder 521 extends and drives the moving plate 1311 to reset. The side clamping plate 131 and the end clamping plate 132 are reset under the action of the second spring 135 and the third spring 138, respectively, and clamp the battery 300 again. Then, the turntable 410 rotates and drives the positioning fixture 100 to rotate. During the rotation, the second clamping block 522 automatically disengages from the two L-shaped plates 1316.

[0051] Then, the positioning fixture 100, carrying the positioned battery 300, sequentially enters the laser cleaning station, the nail mounting station, the pre-welding station, the final welding station, and the post-welding inspection station to perform laser cleaning, nail mounting, pre-welding, final welding, and post-welding inspection in sequence.

[0052] Finally, the positioning fixture 100 moves to the battery unloading station along with the turntable 410. The third clamping block 532 can just fit into the slot formed by the two L-shaped plates 1316 on the outer side of the moving plate 1311. Then, the third cylinder 531 retracts and pulls the moving plate 1311 away from the positioning fixture 100, so that the side clamping plate 131 and the end clamping plate 132 release the battery 300, and the unloading robot takes away the battery 300. After the battery 300 is taken away, the third cylinder 531 extends and drives the moving plate 1311 to reset. The side clamping plate 131 and the end clamping plate 132 are reset under the action of the second spring 135 and the third spring 138, respectively. Then, the turntable 410 rotates and drives the positioning fixture 100 to rotate. During the rotation, the third clamping block 532 automatically disengages from the two L-shaped plates 1316.

[0053] Example 2

[0054] This embodiment provides a battery positioning and processing device, which differs from Embodiment 1 in that: Please refer to... Figure 10 In this embodiment, the conveying mechanism 400 adopts a linear conveying mechanism (such as a belt conveyor) in the prior art. The conveying mechanism conveys the positioning fixture 100 linearly in a predetermined direction. Along the conveying direction of the conveying mechanism 400, a battery loading station, a pre-pressing station, a laser cleaning station, a nailing station, a pre-welding station, a final welding station, a post-welding inspection station, and a battery unloading station are arranged in sequence. A battery loading robot (not shown) is arranged at the battery loading station. The pre-pressing mechanism 200 is installed at the pre-pressing station. A battery unloading robot (not shown) is arranged at the battery unloading station. Corresponding laser cleaning equipment, nailing equipment, pre-welding equipment, final welding equipment, and post-welding inspection equipment can be installed at the laser cleaning station, nailing station, pre-welding station, final welding station, and post-welding inspection station, respectively.

[0055] Next, the working principle of this embodiment will be explained.

[0056] In the initial state, cylinder 1 511, cylinder 2 521, and cylinder 3 531 are in the extended state, and multiple positioning fixtures 100 are placed on the conveying surface of the linear conveying mechanism 100, and the linear conveying mechanism 100 is started.

[0057] When the positioning fixture 100 is conveyed to the loading station, the linear conveyor mechanism 100 pauses. The first clamping block 512 can then be inserted into the slots formed by the two L-shaped plates 1316 on the outer side of the moving plate 1311. Then, the first cylinder 511 retracts, pulling the moving plate 1311 away from the positioning fixture 100, thus increasing the area between the side clamping plate 131 and the end clamping plate 132. This allows the loading robot to load the two batteries 300 into the two positioning slots 110 respectively. After the batteries 300 enter the positioning slots 110, the first cylinder 511 extends, causing the moving plate 1311 to reset. The side clamping plate 131 and the end clamping plate 132 reset under the action of the second spring 135 and the third spring 138, respectively, and clamp the batteries 300 again. Then, the linear conveyor mechanism 100 continues to convey the positioning fixture 100 forward. During this movement, the first clamping block 512 automatically disengages from the two L-shaped plates 1316.

[0058] When the positioning fixture 100 is conveyed to the pre-pressing station, the linear conveying mechanism 100 pauses. The second clamping block 522 can just fit into the slot formed by the two L-shaped plates 1316 on the outer side of the moving plate 1311. Then, the second cylinder 521 retracts and pulls the moving plate 1311 away from the positioning fixture 100, so that the side clamping plate 131 and the end clamping plate 132 release the battery 300. The fourth cylinder 220 drives the pre-pressing plate 230 to move downward and squeeze the battery 300 so that the first spring 121 is compressed, thereby adjusting the height of the battery 300. When the height of the battery 300 reaches the predetermined height, the second cylinder 521 extends and drives the moving plate 1311 to reset. The side clamping plate 131 and the end clamping plate 132 are reset under the action of the second spring 135 and the third spring 138, respectively, and clamp the battery 300 again. Then, the linear conveying mechanism 100 continues to convey the positioning fixture 100 forward. During the movement, the second clamping block 522 automatically disengages from the two L-shaped plates 1316.

[0059] Then, the positioning fixture 100, carrying the positioned battery 300, sequentially enters the laser cleaning station, the nail mounting station, the pre-welding station, the final welding station, and the post-welding inspection station to perform laser cleaning, nail mounting, pre-welding, final welding, and post-welding inspection in sequence.

[0060] Finally, the positioning fixture 100 is conveyed to the battery unloading station. The third clamping block 532 can just fit into the slot formed by the two L-shaped plates 1316 on the outer side of the moving plate 1311. Then, the third cylinder 531 retracts and pulls the moving plate 1311 away from the positioning fixture 100, so that the side clamping plate 131 and the end clamping plate 132 release the battery 300, and the unloading robot takes away the battery 300. After the battery 300 is taken away, the third cylinder 531 extends and drives the moving plate 1311 to reset. The side clamping plate 131 and the end clamping plate 132 are reset under the action of the second spring 135 and the third spring 138, respectively. Then, the linear conveying mechanism 100 continues to convey the positioning fixture 100 forward. During the movement, the third clamping block 532 automatically disengages from the two L-shaped plates 1316.
