Description

Technical Field

[0001] The present disclosure relates to the field of welding technology, and in particular to a welding clamping device, a correction device and welding equipment. Background Art

[0002] Laser welding is a key process in the battery production process. The quality of welding directly affects the safety, reliability and service life of the battery. The quality of the pressing effect of the welding head on the two workpieces to be welded directly affects the welding effect.

[0003] As battery designs become thinner and lighter, welding space becomes smaller and smaller. To ensure welding effect, welding rams are also getting smaller and smaller, and the pressing angle requirements are getting higher and higher. However, during repeated use, the welding ram will have angle twisting problems due to various reasons, resulting in a pressing gap when the ram and the workpiece are rigidly pressed together, making it difficult to ensure the pressing effect of the ram, resulting in poor welding in some locations.

DETAILED DESCRIPTION

[0033] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0034] In the present disclosure, unless otherwise stated, the directional terms "inside" and "outside" used are defined based on the structure of the relevant components themselves. For example, the first air channel connecting the air inlet connector and the plurality of second pipe connectors is provided "inside" the first back plate, which means that the first air channel is provided inside each surface of the first back plate. The directional terms "front" and "rear" used are defined based on the positional relationship of the relevant components. For example, the "front" end face of the pressing block can pass through the corresponding calibration hole, and the "front end face" here refers to the end face of the pressing block facing the calibration block, that is, the end face of the pressing block in contact with the component to be welded.

[0035] In addition, in the present disclosure, the terms "first", "second", etc. are used to distinguish one element from another element, and have no order or importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] Reference Figure 1-Figure 3The present disclosure exemplarily provides a welding clamping device, including a first back plate 100 provided with a first through hole 101, a pressure head assembly 200 provided with a second through hole 201, a guide bolt 310 and a locking nut 320, and an elastic member 400 elastically connected between the first back plate 100 and the pressure head assembly 200. Among them, the guide bolt 310 passes through the second through hole 201 and the first through hole 101 in sequence, and the locking nut 320 is screwed on the guide bolt 310 to position the pressure head assembly 200 on the first back plate 100. Here, it needs to be explained that the aforementioned "to position the pressure head assembly 200 on the first back plate 100", the "positioning" here refers to locking the relative position of the pressure head assembly 200 and the first back plate 100, that is, by locking the guide bolt 310, it is ensured that the pressure head assembly 200 can be fixed to the first back plate 100 to maintain the position and angle before locking (after adjustment).

[0037] The present disclosure does not limit the number of the first through holes 101 and the second through holes 201. Figure 1 and Figure 2 In the illustrated embodiment, the pressure head assembly 200 may be provided with three second through holes 201, and correspondingly, the number of the first through holes 101 may also be three. In addition, in some other embodiments, the pressure head assembly 200 may be provided with four second through holes 201, and correspondingly, the number of the first through holes 101 may be four. It should be noted that when the number of the pressure head assemblies 200 is multiple, the number of the first through holes 101 also needs to be adaptively increased. The number of guide bolts 310 and locking nuts 320 can be adaptively adjusted according to the number of the first through holes 101 and the second through holes 201.

[0038] In the embodiment of the present disclosure, the portion of the guide bolt 310 located on the side of the pressure head assembly 200 away from the first back plate 100 can be constructed as a large head section to abut against the pressure head assembly 200; the portion of the guide bolt 310 located on the side of the first back plate 100 away from the pressure head assembly 200 can be provided with an external thread, so that the locking nut 320 can be screwed to abut against the first back plate 100 to achieve the positioning and locking of the pressure head assembly 200. In this case, the guide bolt 310 needs to pass through the second through hole 201 and the first through hole 101 in sequence. In addition, in some other embodiments, the guide bolt 310 can also pass through the first through hole 101 and the second through hole 201 in sequence, that is, the locking nut 320 can be screwed to abut against the pressure head assembly 200 to achieve the positioning and locking of the pressure head assembly 200, and the present disclosure does not limit this.

[0039] The present disclosure does not limit the elastic member 400 , which may be a coil spring as will be described below, or a rubber column or the like.

[0040] Through the above technical solution, before use, the guide bolt 310 can be placed in a free state by screwing the locking nut 320, so that the position and angle of the pressure head assembly 200 can be adjusted by manually compressing the elastic member 400. After adjustment, the locking nut 320 can be screwed to lock the pressure head assembly 200 on the first back plate 100 and maintain the adjusted state (position and angle) to ensure that the angle and position of the pressure head assembly 200 can meet the clamping requirements during welding, so that during processing, the two parts to be welded can be pressed into place to ensure the welding effect, especially when the welding clamping device has multiple pressure head assemblies 200. The aforementioned adjustment can also be used to ensure the consistency of the positions and angles between the multiple press head assemblies 200, so as to ensure that multiple groups of parts to be welded can be pressed into place when processing multiple workpieces. In addition, when using multiple press head assemblies 200 for pressing, since an elastic member 400 is provided between each press head assembly 200 and the first back plate 100, the pressing into place can be ensured by the elastic force of the elastic member 400, and through the different compression amounts between the elastic members 400, it can be ensured that each press head assembly 200 can make the welding positions of the first part to be welded and the second part to be welded fit and press tightly, thereby improving the welding effect.

[0041] As described above, the present disclosure does not limit the type of the elastic member 400. For example, in the embodiment of the present disclosure, the elastic member 400 may be a coil spring sleeved on the corresponding guide bolt 310. In addition, in some other embodiments, the elastic member 400 may also be a rubber column supported between the pressure head assembly 200 and the first back plate 100.

[0042] Reference Figure 2In the embodiment of the present disclosure, the ram assembly 200 may further include: a second back plate 210, the second back plate 210 is provided with a second through hole 201; and a ram body 220, which is detachably mounted on the side of the second back plate 210 away from the first back plate 100. With such a design, the ram body 220 can be replaced separately when it is damaged, without replacing the ram assembly 200 as a whole, thereby reducing production costs. The cross section of the ram body 220 in the direction away from the second back plate 210 may gradually become smaller, and the ram assembly 200 may further include a pressing block 202 disposed at the end of the ram body 220 away from the second back plate 210, and the pressing block 202 is used to press the first part to be welded to the second part to be welded. The use of such a construction method with a gradually decreasing cross section can make it more convenient for the ram assembly 200 to be used in a narrow space inside the battery, avoiding the situation where the space is too small to be used. In the embodiment of the present disclosure, the pressing block 202 can be integrally formed with the pressing head body 220, or can be connected as a whole by assembly. It should be explained that the first part to be welded and the second part to be welded here refer to two parts in the battery that need to be connected by welding, such as the positive electrode and copper foil, the negative electrode and aluminum foil, etc. The present disclosure does not limit the specific type thereof. The first part to be welded is pressed against the second part to be welded by the pressing block 202 so that the welding positions of the two parts fit in place to avoid gaps, thereby ensuring the welding effect.

[0043] The present disclosure does not limit the connection method between the pressure head body 220 and the second back plate 210. For example, in an embodiment of the present disclosure, the pressure head body 220 and the second back plate 210 can be positioned by positioning pins and then locked by screws.

[0044] The present disclosure does not limit the number of the press head assembly 200. For example, in some embodiments, the number of the press head assembly 200 can be multiple. As described above, in this case, the above-mentioned adjustment can also be used to ensure the consistency of the position and angle between the multiple press head assemblies 200, so as to ensure that multiple groups of parts to be welded can be pressed into place when processing multiple workpieces. In addition, when multiple press head assemblies 200 are used for pressing, since elastic members 400 are provided between each press head assembly 200 and the first back plate 100, the elastic force of the elastic members 400 can ensure that the pressing is in place, and through the different compression amounts between the elastic members 400, it can be ensured that each press head assembly 200 can be attached to and pressed against the position to be welded, thereby improving the welding effect.

[0045] When the number of the pressure head assembly 200 is more than one, refer to Figure 1In the embodiment of the present disclosure, each pressure head assembly 200 may be provided with a first pipe joint 203, and the first back plate 100 may be provided with a plurality of second pipe joints 102, and the plurality of second pipe joints 102 may be connected to the corresponding first pipe joints 203 through pipelines (not shown in the figure, such as hoses). Among them, the first back plate 100 may be provided with an air inlet joint (not shown in the figure) for connecting the gas source, and the air inlet joint may be connected to the air inlet ends of the plurality of second pipe joints 102 respectively; the pressing block 202 may be provided with an air outlet 204 facing the corresponding position to be welded, and the first pipe joint 203 may be connected to the air outlet 204 of the pressing block 202. With such a design, when the welding clamping device is installed on the welding equipment, the gas source can be quickly connected to the air inlet joint, so that the gas can flow to different first pipe joints 203 through different second pipe joints 102, and then flow to the air outlet 204 through the first pipe joint 203 and be discharged from 204 to protect the molten pool of the welding position. Gases usually use inert gases such as helium, argon, and nitrogen to prevent the workpiece from being oxidized during the welding process. In addition, the gas circuit design disclosed in the present invention can realize the quick replacement of the welding clamping device, that is, when replacing different clamping devices, there is no need to connect the gas source with each second pipe joint 102 through a pipeline, and it is only necessary to quickly connect the gas source with the air inlet joint. In addition, since the setting position of the gas source is usually located on the side of the first back plate 100 away from the pressure head assembly 200, it is more conducive to quickly realize the connection between the gas circuit and the gas source by setting the air inlet joint on the side of the first back plate 100 away from the pressure head assembly 200.

[0046] In the embodiment of the present disclosure, a first air passage (not shown in the figure) connecting the air inlet joint and the plurality of second pipe joints 102 may be provided in the first back plate 100, and a second air passage (not shown in the figure) connecting the first pipe joint 203 and the air outlet 204 may be provided in the pressure head assembly 200. The present disclosure does not limit the formation method of the first air passage and the second air passage. For example, in some embodiments, they may be hoses provided in the first back plate 100 or the pressure head assembly 200. Alternatively, in some other embodiments, they may also be formed by a cavity or channel inside the first back plate 100 or the pressure head assembly 200, and the present disclosure does not limit this.

[0047] Reference Figure 1-Figure 3 In an embodiment of the present disclosure, the welding clamping device may further include a fixing assembly 500 installed on the first back plate 100, and the fixing assembly 500 may be used to install the first back plate 100 on the device body of the welding device.

[0048] The present disclosure does not limit the specific structure of the fixing assembly 500. Figure 1 and Figure 3In the illustrated embodiment, the welding device may be provided with a first chuck for cooperating with the fixing assembly 500, and the fixing assembly 500 may include: an internal thread sleeve 510, embedded in the first back plate 100; a spring 520, fixed to the first back plate 100, and a evasion hole 521 may be provided at a position corresponding to the internal thread sleeve 510 of the spring 520; a rivet 530, one end of which passes through the evasion hole 521 and is screwed on the internal thread sleeve 510, and the other end of which is used to cooperate with the first chuck; an anti-rotation member 540, screwed on the rivet 530, and one side of the anti-rotation member 540 abuts against the spring 520; and a washer 550, sleeved on the anti-rotation member 540, for sealing between the first chuck and the anti-rotation member 540. The spring 520 can play a buffering role for the rivet 530 and the anti-rotation member 540. The anti-rotation member 540 is used for clamping the first chuck so that the pressing device can be fixed by the first chuck, and the cross-section of the anti-rotation member 540 is non-circular to prevent the fixing assembly 500 from rotating relative to the first chuck. The gasket 550 can be made of rubber material and is arranged between the first chuck and the anti-rotation member 540 to seal through the gasket 550 to prevent air leakage.

[0049] Reference Figure 1 and Figure 3 In the embodiment of the present disclosure, the number of the fixing components 500 can be two and they are symmetrically installed on both sides of the first back plate 100. Among them, one of the two fixing components 500 can be used to cooperate with the first chuck. With such a design, when one of the fixing components 500 fails or the positioning is not accurate enough, it can be directly switched to another fixing component 500 to cooperate with the first chuck, so as to avoid affecting the welding progress and improve the service life of the clamping device. In addition, two groups of fixing components 500 are set, one of which can be used to cooperate with the first chuck, and the second group can be used for the convenience of the operator to hold.

[0050] According to a second aspect of the present disclosure, a correction device for the above-mentioned welding clamping device is provided, comprising: a base frame 600, for installing the welding clamping device; a guide mechanism 700; and a calibration block 800, which is installed on the guide mechanism 700 so that the calibration block 800 can reciprocate in a direction close to or away from the welding clamping device, and the calibration block 800 is provided with at least one calibration hole 801. Among them, the inner contour of the calibration hole 801 matches the outer contour of the pressure block 202, so that when the calibration block 800 moves in a direction close to the welding clamping device, the pressure block 202 can extend into the calibration hole 801. It should be explained that "the inner contour of the calibration hole 801 matches the outer contour of the pressure block 202" means that the two have the same cross-section along the direction perpendicular to the movement direction of the calibration block 800, for example, both can be Figure 4 and Figure 5The rectangle shown, or both can be circular. The size relationship between the two is a clearance fit, and the clearance allows the two to move relative to each other and the inner contour of the calibration hole 801 can be matched with the outer contour of the pressure block 202 to limit the angle of the pressure block 202. With such a design, when the calibration block 800 moves toward the clamping device, the pressure block 202 can be extended into the calibration hole 801 to adjust the angle of the pressure block 202 through the calibration hole 801, and the position of the pressure block 202 can be adjusted by compressing the elastic member 400 through the pressure head assembly 200. After it is at an angle and position that meets the welding pressure requirements, it can be positioned by screwing the locking nut 320.

[0051] Reference Figure 4-Figure 5 In some embodiments, the welding clamping device may include a plurality of pressure head assemblies 200, and the calibration block 800 may be provided with a plurality of calibration holes 801, so that when the calibration block 800 moves in a direction close to the welding clamping device, the plurality of pressure blocks 202 may extend into the corresponding calibration holes 801 respectively, and the calibration block 800 may push the plurality of pressure head assemblies 200 to compress the corresponding elastic members 400 respectively. Such a design may also keep the positions and angles of the plurality of pressure blocks 202 consistent. Here, "keeping the positions and angles consistent" means that the front end faces of the plurality of pressure blocks 202 for contacting the parts to be welded keep the positions consistent in the direction of movement of the calibration block 800, and the front end faces of the plurality of pressure blocks 202 remain parallel to each other.

[0052] It should be explained that “the inner contour of the calibration hole 801 matches the outer contour of the pressing block 202” means that the two have the same cross section along the direction perpendicular to the movement direction of the calibration block 800, for example, both can be Figure 4 and Figure 5 The rectangle shown, or they can all be circular. The size relationship between the two is a clearance fit, which allows the two to move relative to each other and can limit the angle of the pressing block 202 by matching the inner contour of the calibration hole 801 with the outer contour of the pressing block 202, so that the front end faces of the multiple pressing blocks 202 can remain parallel (within the allowable error range). In other words, since the angles and positions of the multiple calibration holes 801 are consistent, when the multiple pressing blocks 202 are respectively installed in the corresponding calibration holes 801 in a shape-matched manner and the elastic member 400 is compressed (ensuring that the pressing block 202 moves into place in the calibration hole 801 and cannot continue to move relative to each other), it can indirectly ensure that the positions and angles between the multiple pressing blocks 202 are consistent.

[0053] In order to further understand the technical solution, an example is given here for explanation. Assume that there are three pressure head assemblies 200, and the positions of the pressure blocks 202 of the three pressure head assemblies 200 in the movement direction of the calibration block 800 are different. The distances of the first pressure block, the second pressure block, and the third pressure block extending from the pressure head assembly 200 decrease successively, and the angles of the front end faces of the three pressure blocks are also different. In this case, the calibration block 800 gradually moves closer to the pressure head assembly 200, and the three pressure blocks 202 are respectively extended into the corresponding calibration holes 801. Due to the relationship between the outer contour of the pressure block 202 and the inner contour of the calibration hole 801, the angles of the front end faces of the three pressure blocks 202 can be ensured to be consistent. In addition, during the continuous movement of the calibration block 800, the first pressure block will first move to the extreme position with the calibration hole 801, and the calibration block 800 will first push the pressure head assembly 200 corresponding to the first pressure block to move and compress the elastic member 400. The second pressure block and the third pressure block will perform the corresponding process of the first pressure block in turn until the three pressure blocks 202 all move to the extreme position with the calibration hole 801. At this time, the positions and angles of the three pressure blocks 202 can be kept consistent, and then the locking nut 320 is screwed until it presses against the first back plate 100, so as to keep the elastic member 400 and the pressure head assembly 200 in the original position and original angle and position and fix them to meet the consistency.

[0054] Reference Figure 4-Figure 5 In the embodiment of the present disclosure, the calibration hole 801 can be configured as a through hole. When the calibration block 800 moves in a direction close to the welding clamping device, the front end face of the pressing block 202 can pass through the corresponding calibration hole 801, and the calibration block 800 can push the front side of the pressure head assembly 200 to move to compress the elastic member 400 when the pressing block 202 and the calibration hole 801 are relatively stationary. The calibration hole 801 is configured as a through hole so that the front end face of the pressing block 202 can pass through the corresponding calibration hole 801, which can improve the matching stroke of the pressing block 202 and the calibration hole 801, thereby further ensuring the consistency of the angle and position between multiple pressing blocks 202. When the front end faces of the multiple pressing blocks 202 all pass through the corresponding calibration holes 801 (relative movement to the extreme position, that is, the two are relatively still), at this time, since the positions and angles of the multiple calibration holes 801 are consistent, and the positional relationship between each pressing block 202 and the corresponding calibration hole 801 is consistent, the positions and angles of the various pressing blocks 202 can be guaranteed to be consistent. At this time, the calibration block 800 continues to move so as to push the front side of the pressure head assembly 200 and compress the elastic member 400. At this time, screwing the locking nut 320 can fix and maintain the position and angle of the pressure head assembly 200.

With such a design, when calibrating different welding clamping devices, only the calibration portion 820 needs to be replaced, and there is no need to remove the calibration block 800 as a whole from the guide mechanism 700, which is convenient and quick to operate.

[0056] The present disclosure does not limit the connection method between the calibration part 820 and the base part 810. For example, the calibration part 820 and the base part 810 can be connected by screws, bolts, etc.

By setting the second chuck 900, the welding clamping device can be quickly installed or disassembled, and it is only necessary to control the opening and closing of the second chuck 900, and the fixing of the second chuck 900 is stable and the positioning is accurate. The consistency of the structure of the first chuck and the second chuck 900 can ensure that the welding clamping device is installed on the second chuck 900 and the angle of the first chuck is consistent, thereby ensuring that the clamping device that has been calibrated by the correction device can be directly used for the welding equipment, because the installation environment of the clamping device is consistent.

[0060] The present disclosure does not limit the type of the second chuck 900 , and it may be, for example, a pneumatic chuck, an electric chuck, a hydraulic chuck, etc.

With such a design, the calibration block 800 is mounted on the slider 720, and when calibration is required, it is only necessary to control the slider 720 to drive the calibration block 800 to reciprocate. It can be specifically implemented in an electric or manual manner, and the operation is convenient and fast. The present disclosure does not limit the specific structure of the guide rail 710, for example, it may include two straight segments that are spaced apart from each other and extend in parallel, and the slider 720 is installed between the two straight segments. In addition, in some other embodiments, the guide rail 710 may be a flat plate, and a guide groove may be provided on the flat plate, and the slider 720 is at least partially mounted in the guide groove and can reciprocate along the extension direction of the guide groove.
