Description

Technical Field

[0001] This invention relates to the field of wire harness isolation plate processing technology, and in particular to an automatic assembly and welding equipment for battery wire harness isolation plates for new energy electric vehicles. Background Technology

[0002] Battery harness separators for new energy electric vehicles are thin, sheet-like structural components installed inside power battery modules. They provide insulation, protection, and positioning between high-voltage harnesses and components such as cells and casings, preventing short circuits and damage caused by vibration, friction, or impact. Separators typically require fasteners, guides, and other components to secure the harnesses. Since separators are mostly made of engineering plastics, while fasteners are made of metal or rigid plastic, laser embedding welding machines can use high-energy lasers to instantly melt localized materials, firmly embedding the components inside the separator. This achieves high-strength, glue-free, and high-temperature resistant fastening, while also offering high precision and suitability for automated production.

[0003] In existing technologies, the welding quality of the card holder and the isolation plate is generally inspected by static vision. Specifically, the welded isolation plate is moved to the inspection camera lens and the surface image is taken to judge the quality of the weld. Although this method can quickly identify obvious appearance defects, it is difficult to effectively detect hidden problems such as the internal bonding strength, insufficient embedding depth or cold welding, and it is easy to miss the detection. Summary of the Invention

[0004] The purpose of this invention is to address the problem that in the prior art, the welding quality of the card holder and the separator plate is generally inspected using static visual inspection. Specifically, the welded separator plate is transferred to the inspection camera lens, and the quality of the weld point is judged by taking a surface image. Although this method can quickly identify obvious appearance defects, it is difficult to effectively detect hidden problems such as the internal bonding firmness of the weld point, insufficient embedding depth, or poor welding, which easily leads to missed detections. Therefore, this invention proposes an automatic assembly and welding equipment for the battery harness separator plate of new energy electric vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic assembly and welding equipment for battery harness isolation plates for new energy electric vehicles includes a laser embedding welding machine, a detection camera, and an extension frame. A top horizontal guide frame is symmetrically fixed on the top of the extension frame, and a clamping and transfer component is provided on the side of the top horizontal guide frame. The clamping and transfer component pulls the welded wire harness isolation plate from the welding position of the laser embedding welding machine to the detection position.

[0007] The extension frame has a vertical guide post fixedly installed at one end of the top horizontal guide frame. A vertical shaking component is installed between the two vertical guide posts. The vertical shaking component applies vertical shaking to the clamping and transfer component to detect the welding quality of the wire harness holder on the isolation plate.

[0008] The top of the top horizontal guide frame is provided with a vibration lock integrated switching mechanism, which is used to switch the vertical movement state between the clamping and transfer assembly and the extension frame. The switching includes: First state - allowing the clamping and transfer assembly to generate reciprocating vibration in the vertical direction to detect the vibration of the clamped isolation plate and its welded parts;

[0009] The second state restricts the free movement of the clamping and transfer assembly in the vertical direction, so that it maintains rigid support in the vertical direction during detection, handling or positioning.

[0013] Optionally, the vertical shaking assembly includes an edge crossbar, a shaking motor, a drive cam, a force-bearing frame, and a triangular guide block. Rectangular guide posts are fixedly installed at both ends of the edge crossbar, and the rectangular guide posts extend into the vertical grooves opened on the side of the vertical guide posts. A shaking motor is fixedly installed at the middle position of the side of the edge crossbar, and a drive cam is fixedly installed at the output end of the shaking motor. The force-bearing frame is fixedly installed at the top of the receiving frame, and a triangular guide block is fixedly installed on the side of the force-bearing frame.

[0014] Optionally, the vibration lock integrated switching mechanism includes a follower column and a restraint plate. The restraint plate is fixedly installed on the top of the top horizontal guide frame. The restraint plate has a stationary horizontal groove and a release horizontal V-groove opened sequentially on its side. The follower column is fixedly installed on the side of the extension block. The follower column extends into the stationary horizontal groove or the release horizontal V-groove.

[0015] Optionally, the interlocking protection assembly includes a bottom cylinder, a protection plate, and a secondary rigid locking assembly. The bottom cylinder is fixedly installed at the bottom of the guide slope side, and the protection plate is fixedly installed at the output end of the bottom cylinder.

[0016] Optionally, the safety cylinder housing is fixedly mounted on the top of the top horizontal guide frame, a vertical rod is fixedly mounted on the output end of the safety cylinder, a common plate is fixedly mounted on the side of the vertical rod, a limiting horizontal groove is opened on the side of the vertical rod and the bottom of the side of the common plate, and a release short V groove is opened on the common plate at the position of the limiting horizontal groove.

[0018] Optionally, the second micro switch is fixedly mounted on the side of the vertical guide post, and the second micro switch is connected to the bottom cylinder control circuit.

[0019] Optionally, a locking bolt is screwed into the housing above the discharge port of the laser embedding welding machine, a vertical guide frame is movably inserted into the outer wall of the locking bolt, and a transparent cover is fixedly installed at the bottom of the vertical guide frame.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. This invention, by setting a vertical shaking component on the clamping and transfer assembly and cooperating with a vibration-lock integrated switching mechanism, enables the isolation plate to undergo controlled vertical shaking after being transferred to the detection position. Through shaking detection, the vibration environment experienced by the isolation plate and its welding holder under actual working conditions can be simulated. If there are problems such as weak weld joints, incomplete welds, or insufficient embedding depth, the welded parts will loosen or fall off during the shaking process, which will be promptly identified by the detection camera set on the side of the extension frame. Compared with the single static visual inspection method in the prior art, this invention can inspect the welding quality from the perspective of dynamic mechanical response, making up for the deficiency of visual inspection in being unable to identify internal defects, and greatly improving the accuracy and reliability of weld quality judgment.

[0022] 2. The present invention is equipped with a vibration-lock integrated switching mechanism, which can realize the switching of vertical motion mode under different processes. When vibration detection is performed, the clamping and transfer component is in a vibratory state to ensure that the isolation plate can withstand vertical shaking impact. When the workpiece is transported, the vibration-lock integrated switching mechanism switches to vertical rigid mode to restrict the degree of freedom of the clamping component and ensure that the workpiece position is stable and does not shift. Through this automatic switching of dual modes, the workpiece is ensured to remain stable during the transfer and positioning process without shifting or shaking.

[0023] 3. To ensure that the isolation plate held by the clamping and transfer assembly does not vibrate during visual inspection, this invention additionally provides an interlocking protection component. When the vertical vibration component is working, the interlocking protection component blocks the detection camera lens to prevent parts accidentally shaken off the isolation plate from damaging the camera. When the detection camera is working, the clamping and transfer assembly is restricted to a second state, locking the vertical degree of freedom of the clamping and transfer assembly, thus avoiding problems such as blurred camera imaging or recognition errors caused by workpiece vibration during the inspection process.

[0024] 4. The core component of the interlocking protection assembly of the present invention is a secondary rigid locking assembly. The extension action of a safety cylinder realizes the vertical freedom of the locking clamping and transfer assembly on the one hand, and raises the power source of the vertical shaking assembly to a certain height on the other hand, directly preventing the vertical shaking assembly from being accidentally activated. This effectively prevents the shaking mechanism from being accidentally activated in non-detection processes, thereby avoiding damage to the workpiece or affecting production safety. It achieves dual protection of clamping stability and shaking safety, avoiding the problem of blurred camera imaging or recognition error caused by workpiece shaking during the detection process.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] Reference Figure 1-11An automatic assembly and welding equipment for battery harness separators in new energy electric vehicles includes a laser embedding welding machine 1, an inspection camera 10, and an extension frame 7. The extension frame 7 is fixedly installed at the outlet of the laser embedding welding machine 1. A top horizontal guide frame 8 is symmetrically fixedly installed on the top of the extension frame 7. A locking bolt 3 is screwed into the shell above the outlet of the laser embedding welding machine 1. A vertical guide frame 4 is movably inserted into the outer wall of the locking bolt 3. A transparent cover 2 is fixedly installed at the bottom of the vertical guide frame 4. The transparent cover 2 protects all components installed on the top of the extension frame 7. The transparent cover 2 is made of transparent acrylic sheet material, which also allows users to observe the status of the internal components of the extension frame 7.

[0040] The top horizontal guide frame 8 is provided with a clamping and transfer assembly on its side. The clamping and transfer assembly pulls the welded wire harness isolation plate from the welding position of the laser embedding welding machine 1 to the detection position. The model of the laser embedding welding machine 1 is LMW-200. Its specific structure is existing technology and therefore is not disclosed in this application document. The laser embedding welding machine 1 uses a high energy density laser beam to precisely irradiate the welding area, causing the metal in the welding area to melt instantly and combine with the implant. Then it cools rapidly to form a high-strength weld point.

[0041] The clamping and transfer assembly includes a first micro switch 71, a receiving frame 12, a transfer motor 6, and a drive block 11. The housing of the transfer motor 6 is fixedly mounted on the side of the top horizontal guide frame 8. The side of the top horizontal guide frame 8 has a cavity, and both ends of the top horizontal guide frame 8 are closed. A transfer screw 61 is fixedly mounted on the output end of the transfer motor 6. Since the transfer screw 61 needs to perform a rotational action, in order to make the rotation of the transfer screw 61 smooth, bearings are sleeved on both ends of the transfer screw 61 and inserted into the side of the top horizontal guide frame 8. The drive block 11 is threaded into the outer wall of the transfer screw 61. The drive block 11 extends into the inner cavity of the top horizontal guide frame 8. The cross-sectional dimensions of the drive block 11 and the inner cavity of the top horizontal guide frame 8 are the same, and the contact positions are all ground into smooth surfaces. Therefore, when the transfer screw 61 rotates, the drive block 11 will smoothly move laterally with low resistance along the inner cavity of the top horizontal guide frame 8.

[0042] A vertical guide frame 110 is fixedly mounted on the side of the drive block 11, and a clamping cylinder 14 is fixedly mounted on the top of the receiving frame 12. In order to ensure that the clamping cylinder 14 can only perform its action when it reaches the unloading position of the laser embedding welding machine 1, a first micro switch 71 is required. The first micro switch 71 is connected to the control circuit of the clamping cylinder 14, and the first micro switch 71 is fixedly mounted above the discharge port housing of the laser embedding welding machine 1. When the first micro switch 71 is triggered by the receiving frame 12, the clamping cylinder 14 will then perform its action.

[0043] A clamping plate 141 is fixedly installed at the output end of the clamping cylinder 14. The clamping plate 141 extends into the inner cavity of the receiving frame 12. The clamping plate 141 cooperates with the bottom of the inner cavity of the receiving frame 12 to clamp the isolation plate. In order to prevent the isolation plate from moving laterally along the inner cavity of the receiving frame 12 after being clamped, the length of the inner cavity of the receiving frame 12 and the length of the clamping plate 141 are slightly larger than the width of the isolation plate to be clamped in actual settings.

[0044] In order to allow the receiving frame 12 to move freely in the vertical direction, extension blocks 15 are fixedly provided at both ends of the receiving frame 12. The extension blocks 15 extend into the inner cavity of the vertical guide frame 110. Limiting plates 151 are fixedly provided on both sides of the vertical guide frame 110 for the extension blocks 15. The limiting plates 151 restrict the extension blocks 15 to move freely in the vertical direction only along the outer wall of the vertical guide frame 110. In order to reduce the contact resistance between the limiting plates 151 and the vertical guide frame 110, auxiliary wheels 1510 are rotatably provided on the side of the limiting plates 151. The auxiliary wheels 1510 replace the limiting plates 151 and contact the vertical guide frame 110.

[0045] A vertical column 16 is movably inserted into the bottom of the extension block 15. A retaining spring 17 is movably sleeved under the extension block 15. The retaining spring 17 needs to be set with a certain preload. When the receiving frame 12 is not under pressure, the retaining spring 17 will push the extension block 15 up to the top of the inner cavity of the vertical guide frame 110. When the receiving frame 12 captures the isolation plate, the retaining spring 17 will keep the extension block 15 at a certain height in the inner cavity of the vertical guide frame 110, so that the receiving frame 12 still has a certain displacement space in the vertical direction.

[0046] The extension frame 7 has a vertical guide post 80 fixedly installed at one end of the top horizontal guide frame 8. A vertical shaking component is installed between the two vertical guide posts 80. The vertical shaking component applies vertical shaking to the clamping and transfer component to detect the welding quality of the wire harness holder on the isolation plate. The vertical shaking component includes an edge crossbar 19, a shaking motor 18, a drive cam 181, a force-bearing frame 13, and a triangular guide block 131.

[0047] Rectangular guide posts 191 are fixedly installed at both ends of the edge crossbar 19. The rectangular guide posts 191 extend into the vertical groove 801 opened on the side of the vertical guide post 80. A shaking motor 18 is fixedly installed at the middle position of the side of the edge crossbar 19. A drive cam 181 is fixedly installed at the output end of the shaking motor 18. The force-bearing frame 13 is fixedly installed on the top of the receiving frame 12. Obviously, the power source of the vertical shaking component, i.e., the shaking motor 18, and the force-bearing component, i.e., the force-bearing frame 13, are set separately. Therefore, the vertical shaking component can only be activated after the clamping and transfer component captures the isolation plate and suspends the isolation plate in a vertical state, avoiding no-load or accidental triggering of shaking, and preventing the vertical shaking component from running ineffectively and damaging the parts.

[0048] Since the drive cam 181 typically includes a lift area, a rest area, and a return area, when the vibrating motor 18 stops, it is impossible to guarantee what kind of area is directly below the drive cam 181. In order to enable the drive cam 181 to move smoothly to the top of the force-bearing frame 13, a triangular guide block 131 is fixedly provided on the side of the force-bearing frame 13. The top of the triangular guide block 131 is set as an inclined surface, and the lowest end of the triangular guide block 131 is close to one side of the drive cam 181.

[0049] The top of the top horizontal guide frame 8 is equipped with a vibration lock integrated switching mechanism, which is used to switch the vertical movement state between the clamping and transfer assembly and the extension frame 7. The switching includes two states: the first state allows the clamping and transfer assembly to generate reciprocating vibration in the vertical direction to detect the vibration of the clamped isolation plate and its welded parts; the second state allows the clamping and transfer assembly to be restricted from free movement in the vertical direction, so that it maintains rigid support in the vertical direction during detection, handling or positioning.

[0050] An extension frame 7 is fixedly provided with a docking plate 73 on one side near the laser embedding welding machine 1. A guide slope 730 is fixedly provided on the side of the docking plate 73. A detection camera 10 is fixedly provided inside the guide slope 730. An interlocking protection component is provided on the side of the guide slope 730. When the vertical shaking component is working, the interlocking protection component blocks the lens of the detection camera 10. When the detection camera 10 is working, it restricts the clamping and transfer component to the second state, that is, restricts the free movement of the clamping and transfer component in the vertical direction.

[0051] The vibration lock integrated switching mechanism includes a follower column 152 and a restraint plate 9. The top of the top horizontal guide frame 8 is fixedly provided with the restraint plate 9. The side of the restraint plate 9 is sequentially provided with a stationary horizontal groove 91 and a release horizontal V groove 92. The side of the extension block 15 is fixedly provided with the follower column 152, which extends into the stationary horizontal groove 91 or the release horizontal V groove 92.

[0052] The interlocking protection assembly includes a bottom cylinder 5, a protection plate 51, and a secondary rigid locking assembly. The bottom cylinder 5 is fixedly installed at the bottom side of the guide slope 730, and the protection plate 51 is fixedly installed at the output end of the bottom cylinder 5. A detection camera 10 is fixedly installed inside the guide slope 730. To prevent the bottom of the isolation plate from falling directly to the ground when it is pulled by the clamping and transfer assembly, the docking plate 73 and the guide slope 730 must be installed. The secondary rigid locking assembly includes a second micro switch 72, a safety cylinder 20, a common plate 21, a vertical rod 201, and a secondary column 1920. The housing of the safety cylinder 20 is fixedly installed at the top of the top horizontal guide frame 8. The automatic switch 72 is fixedly installed on the side of the vertical guide post 80. The second micro switch 72 is connected to the control circuit of the safety cylinder 20. A vertical rod 201 is fixedly installed at the output end of the safety cylinder 20. A common plate 21 is fixedly installed on the side of the vertical rod 201. Limiting transverse grooves 22 are opened on the side of the vertical rod 201 and the bottom of the side of the common plate 21. A release short V groove 23 is opened at the position of the limiting transverse groove 22 on the common plate 21. The top surface of the release short V groove 23 is parallel to the top surface of the limiting transverse groove 22, and the bottom surface of the release short V groove 23 is an inclined surface. When the follower post 152 enters the interior of the release short V groove 23, the follower post 152 has a certain displacement space in the vertical direction.

[0053] The top of the common plate 21 and the limiting transverse groove 22 is provided with a folded groove 24. The secondary post 1920 extends into the folded groove 24. One end of the secondary post 1920 is fixedly set on the side of the vertical plate 192. The vertical plate 192 is fixedly set at both ends of the bottom of the edge crossbar 19. The folded groove 24 includes a first horizontal section, an inclined section and a second horizontal section. The horizontal height of the first horizontal section is higher than the horizontal height of the second horizontal section. When the secondary post 1920 moves to the second horizontal section of the folded groove 24, the edge crossbar 19 will be raised to the limit position.

[0054] In addition, the length of the follower column 152 needs to be set appropriately. When the safety cylinder 20 is in the retracted state, the release short V groove 23 is flush with the release horizontal V groove 92, and the limit horizontal groove 22 is flush with the stationary horizontal groove 91. The follower column 152 can simultaneously enter the release short V groove 23 and the release horizontal V groove 92, or enter the limit horizontal groove 22 and the stationary horizontal groove 91.

[0055] The specific implementation steps and principles of this invention are divided into the following steps:

[0056] The clamping and transfer assembly captures the welded isolation plate:

[0057] Initially, the secondary column 1920 is located inside the second horizontal section of the folded groove 24, at which point the horizontal height of the edge crossbar 19 is at its lowest. After the laser embedding welding machine 1 completes welding, the control transfer motor 6 is started. The transfer motor 6 drives the transfer screw 61 to rotate, causing the drive block 11 to move towards the laser embedding welding machine 1. During this process, the follower column 152 moves from the release horizontal V-groove 92 to the stationary horizontal groove 91, and the receiving frame 12 cannot move in the vertical direction. When the receiving frame 12 is pressed against the first micro switch 71, When the clamping cylinder 14 moves, it causes the clamping plate 141 to move down. The clamping plate 141 cooperates with the receiving frame 12 to clamp one end of the welded isolation plate. The transfer motor 6 is started to reverse, which drives the drive block 11 to return to the initial position. At this time, the welded isolation plate becomes vertical due to its own weight. The follower column 152 enters the release horizontal V groove 92 and the release short V groove 23. The receiving frame 12 can move freely in the vertical direction. At this time, the drive cam 181 is guided to the top of the force frame 13 through the triangular guide block 131.

[0058] The vertical shaking component causes the welded isolation plate to shake vertically.

[0059] Start the vibration motor 18, which drives the drive cam 181 to rotate. The drive cam 181 intermittently applies downward pressure to the force frame 13, while the holding spring 17 intermittently drives the receiving frame 12 to return to its initial position. The receiving frame 12 vibrates back and forth in the vertical direction. At this time, the bottom cylinder 5 is in the extended state, and the protective plate 51 blocks the lens of the detection camera 10. Assuming there is a poorly welded wiring seat on the side of the isolation plate, the wiring seat will be shaken off.

[0060] Camera 10 performs defect detection on the isolation plates:

[0061] The safety cylinder 20 is activated, extending and moving the common plate 21 until the second micro switch 72 is triggered by the common plate 21. At this time, the bottom cylinder 5 retracts, causing the protection plate 51 to move away from the lens of the detection camera 10. During this process, the end of the follower column 152 enters the limit groove 22, and the receiving frame 12 cannot move in the vertical direction. At the same time, the secondary column 1920 moves to the second horizontal section of the folded groove 24. At this time, the edge crossbar 19 is raised to the limit position. Even if the shaking motor 18 is activated and drives the drive cam 181 to rotate, the drive cam 181 cannot contact the force frame 13. The detection camera 10 is activated and takes a picture of the isolation plate.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
