Abstract

The present application relates to the technical field of wire harness crimping detection, and in particular to a multi-station wire harness crimping and detection machining center. An image acquisition device is arranged on the top of the lower pressing head of the crimping device and changes position according to the movement of the upper pressing head. The transmission mechanism comprises a sliding block that moves synchronously with the upper pressing head and a sliding assembly that cooperates with the sliding block and has a constant horizontal height. The vertical movement of the upper pressing head is converted into the horizontal movement of the image acquisition device through the sliding block that is linked with the crimping action of the upper pressing head and the sliding assembly that cooperates with the combined surface of the sliding block. When the upper pressing head is pressed down for crimping, the image acquisition device can automatically withdraw horizontally from the working area to make room for the crimping action. When the upper pressing head moves up after crimping is completed, the image acquisition device can automatically and accurately reset to the position directly above the lower pressing head for photographing. The whole process is driven by the crimping action without the need for additional control, and ensures that the visual detection and crimping action do not interfere physically.

Description

Technical Field

[0001] This invention relates to the field of wire harness crimping and testing technology, specifically a multi-station wire harness crimping and testing processing center. Background Technology

[0002] Wire harness crimping is one of the core processes in wire harness manufacturing. It refers to the process of using a special crimping die to plastically deform the metal part of the terminal (connector) under precisely controlled pressure and stroke, forming a firm, reliable, and inseparable electrical and mechanical connection with the conductor (core) of the wire. Multi-station wire harness crimping refers to the integration of multiple stations with different functions on one machine to complete the processing of a single wire harness. The wire passes through these stations in sequence, completing all steps from raw material to finished product in one processing cycle.

[0003] In some existing technologies, to achieve automatic quality inspection after wire harness crimping, a fixed vision camera is usually installed next to the crimping machine at the crimping station. The fixed camera is usually installed on the side or directly above the crimping mold. However, the installation position of this method is limited. If it is installed directly above, it will interfere with the crimping mold and a large safety distance needs to be reserved. Therefore, it may result in poor shooting angle and image distortion. If it is installed on the side, it is difficult to obtain a front view of the crimped terminal, which may affect the accuracy of the inspection. If it is a removable camera, an independent drive system may be required, which may pose certain risks in terms of timing synchronization. If the inspection is carried out outside the crimping station, there may be defects in the crimped wire harness during transportation, so it is impossible to determine whether the defect was caused during crimping or transportation.

[0004] Therefore, the present invention provides a wire harness crimping and inspection processing center for multi-station wire harness crimping, which performs visual inspection of the crimping effect immediately after crimping without affecting the crimping action. Summary of the Invention

[0005] To address the problem of difficulty in performing real-time and accurate visual inspection of wire harness crimping effects in existing technologies, this invention provides a multi-station wire harness crimping and inspection processing center.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a multi-station wire harness crimping and inspection processing center, including a frame and a crimping device fixedly installed on the frame. The crimping device includes an upper crimping head and a lower crimping head. Bases are provided on both sides of the upper crimping head. An image acquisition device that changes position according to the movement of the upper crimping head is provided on the top of the lower crimping head. A transmission mechanism is provided between the crimping device and the image acquisition device. The transmission mechanism includes a sliding block that moves synchronously with the upper crimping head and a sliding component that cooperates with the sliding block and whose horizontal height remains constant. A connecting mechanism for supporting the transmission mechanism is fixedly connected to the bottom of the base.

[0007] The transmission mechanism is configured to use the downward pressing action of the upper pressure head to cause the image acquisition device to retract from directly above the lower pressure head, and when the upper pressure head is lifted after crimping, it causes the image acquisition device to return to directly above the lower pressure head. The sliding block contacts the sliding component on its non-vertical side. As the sliding block moves up and down with the upper pressure head, the image acquisition device, which is fixedly connected to the sliding component, completes a smooth displacement. The crimping action of the upper pressure head completes the automatic avoidance and reset of the image acquisition device. In conjunction with the limiting component fixedly installed on the upper pressure head, it presses the wire harness to maintain the stability of the wire harness, enabling the image acquisition device to perform visual inspection of the crimped wire harness at a suitable angle and obtain accurate crimping effect image information.

[0008] Preferably, the connecting mechanism includes a first fixing plate and a second fixing plate, the height of the first fixing plate is higher than the height of the second fixing plate, a groove is provided in the base area between the first fixing plate and the second fixing plate, and a second sliding groove is provided on the side of the first fixing plate near the second fixing plate.

[0009] Preferably, the transmission mechanism further includes a connecting plate fixedly connected to one side of the upper pressure head, a connecting column fixedly connected to the bottom of the connecting plate, the bottom of the connecting column fixedly connected to the top of the sliding block, the side of the sliding block near the lower pressure head is set as a combination surface of straight upper and curved lower, and a slide rail is provided to match the combination surface, one end of the sliding component is tumblingly connected to the slide rail, a sensor is fixedly installed on one side of the bottom of the sliding block, and a set of guide members are fixedly connected to the side of the second fixed plate away from the first fixed plate.

[0010] Preferably, the sliding assembly includes a sliding rod that slides through the second fixed plate. A roller is fixedly connected to one end of the sliding rod near the sliding block. The roller cooperates with the slide rail. A connector is fixedly connected to the side of the sliding rod roller near the second fixed plate. An elastic member is fixedly connected to the side of the connector away from the roller. The end of the elastic member away from the connector is fixedly connected to the second fixed plate. A set of symmetrical third sliding grooves are formed on the surface of the sliding rod. A guide member is slidably connected to the third sliding grooves. The bottom of the connector cooperates with the sensor.

[0011] Preferably, the side of the sliding block away from the sliding component is slidably engaged with the second sliding groove.

[0012] Preferably, the crimping device further includes an extension platform fixedly connected to the end of the lower crimp head, and both the lower crimp head and the extension platform have an arc-shaped recess in the middle, with the metal part of the terminal block placed in the arc-shaped recess of the lower crimp head.

[0013] Preferably, the limiting component includes a fixed block located on one side of the upper pressure head mold. The fixed block has a first sliding groove on both sides of its inner end. A set of springs is fixedly connected to the top of the fixed block. A movable block is fixedly connected to the end of the spring away from the top of the fixed block. The two sides of the movable block are slidably connected to the first sliding groove. An arc-shaped slot is provided at the lower end of the movable block, and the movable block cooperates with the extension table.

[0014] Preferably, when the spring is not under force, the vertical distance between the bottom of the movable block and the lower pressure head is less than the vertical distance between the bottom of the upper pressure head and the lower pressure head.

[0015] Preferably, the image acquisition device is fixedly installed at the bottom of the sliding rod at the end away from the roller.

[0016] Preferably, the base is fixedly installed at the lower end of the frame, and the pressing head is fixedly installed at the lower end of the base.

[0017] The beneficial effects of this invention are:

[0018] (1) The multi-station wire harness crimping and inspection processing center of the present invention uses a sliding block that is linked to the crimping action of the upper pressure head and a sliding component that is combined with the curved surface of the sliding block to convert the vertical movement of the upper pressure head into the horizontal movement of the image acquisition device. When the upper pressure head is pressed down to crimp, the image acquisition device can automatically withdraw horizontally from the working area to make room for the crimping action. When the upper pressure head is moved up after the crimping is completed, the image acquisition device can automatically and accurately reset to the position directly above the lower pressure head to take pictures. The whole process is driven by the crimping action without additional control, and ensures that there is no physical interference between visual inspection and crimping action.

[0019] (2) The multi-station wire harness crimping and inspection processing center of the present invention utilizes the "press first, then release" characteristic of the retractable movable block, that is, when pressing down, the lower pressing head presses down on the wire harness first, and when lifting up, it leaves later than the upper pressing head. Combined with the automatic reset of the image acquisition device, it ensures that the wire harness is in a stable state when the image acquisition device reaches the shooting position, so that the acquired image can accurately reflect the real wire harness crimping state and avoid the wire harness displacement or shaking caused by the upper pressing head lifting up.

[0020] (3) The multi-station wire harness crimping and inspection processing center of the present invention has a combined curved surface on the side of the sliding block, which enables the roller to obtain differentiated horizontal displacement when contacting different sections, realizing the combination of rapid avoidance and smooth displacement. At the same time, the elastic element always provides the roller with a pressing force pointing towards the sliding block. The position of the image acquisition device is determined by the vertical height of the sliding block and the contour of the combined curved surface. Attached Figure Description

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1: As Figures 1-8As shown, the multi-station wire harness crimping and inspection processing center of the present invention includes a frame 1 and a crimping device 2 fixedly mounted on the frame 1. The crimping device 2 includes an upper crimping head 21 and a lower crimping head 22. Bases 3 are provided on both sides of the upper crimping head 21. An image acquisition device 7, whose position changes according to the movement of the upper crimping head 21, is provided on the top of the lower crimping head 22. A transmission mechanism 6 is provided between the crimping device 2 and the image acquisition device 7. The transmission mechanism 6 includes a sliding block 63 that moves synchronously with the upper crimping head 21 and a sliding component 66 that cooperates with the sliding block 63 and whose horizontal height remains constant. A connecting mechanism 5 for supporting the transmission mechanism 6 is fixedly connected to the bottom of the base 3. The transmission mechanism 6 is configured to utilize the movement of the upper crimping head 21 and the lower crimping head 22. The pressing action causes the image acquisition device 7 to withdraw from directly above the lower pressing head 22, and when the upper pressing head 21 is lifted after the crimping is completed, the image acquisition device 7 returns to directly above the lower pressing head 22. It contacts the sliding component 66 through the non-vertical side of the sliding block 63. As the sliding block 63 moves up and down with the upper pressing head 21, the image acquisition device 7, which is fixedly connected to the sliding component 66, completes a smooth displacement. It works in conjunction with the limiting component 4 fixedly installed on the upper pressing head 21 to press the wire harness. Utilizing the "press first, then release" characteristic of the limiting component 4, the stability of the wire harness is maintained when the upper pressing head 21 is lifted, causing the image acquisition device 7 to perform visual inspection of the crimped wire harness at a suitable angle and obtain accurate and stable image information.

[0033] In this embodiment, the metal part of the terminal block is placed in the arc-shaped recess of the lower pressure head 22. The wire harness processed at other stations is transported to the crimping station, and the exposed core wire of the wire harness is placed in the metal part of the terminal block. The upper pressure head 21 is located on the base 3 and is slidably connected to the base 3. When the upper pressure head 21 is not pressed down, the roller 662 of the sliding component 66 abuts against the lower end of the sliding block 63. At this time, the image acquisition device 7 is located directly above the lower pressure head 22. When the upper pressure head 21 is pressed down, it drives the sliding block 63 to move down, while the horizontal height of the sliding rod 661 remains unchanged. Therefore, the sliding block 63 follows the upper pressure head. When the upper pressure head 21 moves down, the roller 662 slides within the slide rail 64 and gradually comes into contact with the upper end of the sliding block 63. Under the action of the elastic element 664, the sliding rod 661 moves, causing the image acquisition device 7 to withdraw from directly above the lower pressure head 22 to avoid affecting the crimping action. The pre-crimping limit component 4 presses down on the wire harness first and then delays separating from the wire harness after crimping to maintain the stability of the wire harness. When the upper pressure head 21 is lifted, it drives the sliding block 63 to move up, causing the sliding rod 661 to extend and come to the position directly above the lower pressure head 22, and triggering the sensor 67 to make the image acquisition device 7 take a picture of the crimped wire harness for visual inspection of the crimping effect.

[0034] Specifically, such as Figure 3 , Figure 4 and Figure 8As shown, the crimping device 2 also includes an extension platform 23 fixedly connected to the end of the lower crimp head 22. Both the lower crimp head 22 and the extension platform 23 have arc-shaped recesses in the middle, and the metal part of the terminal block is placed in the arc-shaped recess of the lower crimp head 22. The limiting component 4 includes a fixing block 41 located on one side of the upper crimp head 21 mold. The inner two end side walls of the fixing block 41 are provided with first sliding grooves 43. A set of springs 42 are fixedly connected to the top of the fixing block 41. The end of the spring 42 away from the top of the fixing block 41 is fixedly connected to a movable block 44. The two sides of the movable block 44 are slidably connected to the first sliding grooves 43. The lower end of the movable block 44 is provided with an arc-shaped slot 441, and the movable block 44 cooperates with the extension platform 23. When the spring 42 is not under force, the vertical distance between the bottom of the movable block 44 and the lower crimp head 22 is less than the vertical distance between the bottom of the upper crimp head 21 and the lower crimp head 22.

[0035] In this embodiment, when the upper pressure head 21 of the crimping device 2 presses down, the image acquisition device 7 is withdrawn from directly below the upper pressure head 21 to the side under the cooperation of the connecting mechanism 5 and the transmission mechanism 6. At the same time, as the upper pressure head 21 moves down, the lower end of the movable block 44 first abuts against the extension platform 23, pressing down the unstripped part of the wire harness. As the upper pressure head 21 continues to press down, the spring 42 at the top of the movable block 44 is compressed, and the movable block 44 slides into the fixed block 41. The arc-shaped groove 441 at the lower end of the movable block 44 cooperates with the arc-shaped recess of the lower pressure head 22 to press down the wire harness. Under the pressure of the mold of the upper pressure head 21, the metal part of the crimping terminal is deformed. After the core wire of the wire harness is wrapped and crimped, the upper pressure head 21 moves upward. In the initial stage of upward movement, the upper pressure head 21 mold separates from the wire harness first. At this time, the movable block 44 still presses the wire harness, while the spring 42 gradually relaxes. After the spring 42 is completely relaxed, as the upper pressure head 21 moves upward, the movable block 44 separates from the wire harness. That is to say, when the upper pressure head 21 presses down, the movable block 44 contacts the wire harness one step before the mold, stabilizing the wire harness before the mold crimps it. When the upper pressure head 21 lifts up, the movable block 44 separates from the wire harness one step later than the mold, avoiding the upper pressure head 21 moving upward after crimping and causing the image acquisition device 7 to be unable to capture the wire harness in a stable state.

[0036] Specifically, such as Figures 1-7As shown, the connecting mechanism 5 includes a first fixing plate 51 and a second fixing plate 53. The height of the first fixing plate 51 is higher than that of the second fixing plate 53. A groove 54 is provided in the base 3 area between the first fixing plate 51 and the second fixing plate 53. A second sliding groove 52 is provided on the side of the first fixing plate 51 near the second fixing plate 53. The transmission mechanism 6 also includes a connecting plate 61 fixedly connected to one side of the upper pressure head 21. A connecting column 62 is fixedly connected to the bottom of the connecting plate 61. The bottom of the connecting column 62 is fixedly connected to the top of the sliding block 63. The side of the sliding block 63 near the lower pressure head 22 is set as a combination surface of straight upper and curved lower, and a slide rail 64 that matches the combination surface is provided. One end of the sliding component 66 is tactilely connected to the slide rail 64. A sensor 67 is fixedly installed on one side of the bottom of the sliding block 63. A set of guide members 65 is fixedly connected to the side of the second fixing plate 53 away from the first fixing plate 51. The sliding component 66 includes a sliding through-hole. The sliding rod 661 of the second fixed plate 53 has a roller 662 fixedly connected to one end of the sliding rod 661 near the sliding block 63. The roller 662 cooperates with the slide rail 64. A connector 663 is fixedly connected to the side of the sliding rod 661 near the roller 662 near the second fixed plate 53. An elastic member 664 is fixedly connected to the side of the connector 663 away from the roller 662. The end of the elastic member 664 away from the connector 663 is fixedly connected to the second fixed plate 53. A set of symmetrical third slide grooves 665 are opened on the surface of the sliding rod 661. The guide member 65 is slidably connected to the third slide groove 665. The bottom of the connector 663 cooperates with the sensor 67. The side of the sliding block 63 away from the sliding assembly 66 is slidably engaged with the second slide groove 52. The image acquisition device 7 is fixedly installed at the bottom of the end of the sliding rod 661 away from the roller 662. The base 3 is fixedly installed at the lower end of the frame 1. The pressing head 22 is fixedly installed at the lower end of the base 3.

[0037] In this embodiment, the upper pressure head 21 presses down, causing the connecting plate 61 fixedly connected to it to move downward, thereby causing the sliding block 63 to move downward. When the sliding block 63 moves vertically, it is always slidably engaged with the first fixed plate 51, enhancing its stability. When the upper pressure head 21 moves to its lowest point, the lower end of the sliding block 63 moves into the groove 54. Initially, the roller 662 abuts against the lower end of the sliding block 63. The image acquisition device 7 is located directly above the lower pressure head 22, therefore, when the sliding block 63 moves downward... At this time, roller 662 gradually moves from the lower end of sliding block 63 to the upper end of sliding block 63. Under the action of elastic element 664, it pushes sliding rod 661 to move horizontally towards sliding block 63. The horizontal distance between the upper and lower ends of sliding block 63 is the range of movement of sliding rod 661. When roller 662 abuts against the vertical surface of sliding block 63, sliding rod 661 is withdrawn from directly below upper pressure head 21 to avoid obstructing its movement when pressed by upper pressure head 21. When roller 662 rolls on the inclined surface of sliding block 63, sliding rod 661 moves horizontally. When roller 662 rolls on the vertical surface of sliding block 63, sliding rod 661 remains stationary, only roller 662 rotates. When sliding rod 661 slides horizontally, guide member 65 always slides within the third groove 665, maintaining the stability of sliding rod 661 during movement. During the up-and-down movement of sliding block 63, roller 662 always rolls within slide rail 64. After crimping device 2 completes crimping, upper pressure head 21 moves upward, causing sliding rod 661 to gradually extend. When the lower end of sliding block 63 abuts against roller 662, connector 663 abuts against sensor 67 at the lower end of sliding block 63, triggering image acquisition device 7 to take a picture of the crimped wire harness from directly above lower pressure head 22, acquiring a picture of the crimped wire harness, visually inspecting the crimping effect, detecting whether there are defects or flaws (such as exposed core wires) in the crimped wire harness, and marking defective products.

[0038] like Figure 7 As shown, the combined curved surface of the sliding block 63 is divided into a vertical surface at the top and an inclined surface at the bottom. The connecting bend is set as an arc surface. The roller 662 gradually approaches the vertical surface from the bottom of the sliding block 63. Within the range of the bottom of the sliding block 63, the sliding rod 661 makes a horizontal displacement. When the upper pressure head 21 presses down, the sliding rod 661 and the image acquisition device 7 will not affect the movement of the upper pressure head 21. When the sliding block 63 continues to move down, the roller 662 contacts the vertical surface of the sliding block 63. Within the range of the vertical surface, the horizontal position of the sliding rod 661 remains unchanged, and only the roller 662 rotates on the vertical surface. The crimping device 2 completes the crimping of the wire harness.

[0039] like Figure 5 and Figure 6As shown, the elastic element 664 is set as a spring. When the roller 662 abuts against the upper straight section of the sliding block 63, the elastic element 664 is longer and experiences the least pressure, while the sliding rod 661 extends to its shortest length. As the roller 662 gradually abuts against the lower end of the sliding block 63, the elastic element 664 is compressed. Under the action of the elastic element 664, the sliding rod 661 moves directly above the lower pressure head 22. After triggering the image acquisition device 7 to take a picture, the pressure of the elastic element 664 is released during the next pressing motion, and the sliding rod 661 moves towards the sliding block 63. The sliding rod 661 then retracts from directly below the upper pressure head 21.

[0040] Example 2: Similar to Example 1, except that the elastic element 664 is a permanent magnet and is installed on the side of the connector 663 near the second fixing plate 53. An electromagnet coil that can be switched on and off is installed on the second fixing plate 53. When the upper pressure head 21 is pressed down, the electromagnet is energized, generating a magnetic field that repels the permanent magnet. This causes the electromagnetic force to push the sliding rod 661 to move, thereby causing the image acquisition device 7 to withdraw from directly above the lower pressure head 22 to the side. When the upper pressure head 21 moves up, the electromagnet is de-energized. The permanent magnet is not affected by the electromagnet. When the sliding block 63 moves up, its inclined surface pushes the sliding rod 661 to move directly above the lower pressure head 22 and triggers the sensor 67, causing the image acquisition device 7 to take a picture of the wire harness.

[0041] Working principle: During use, the wire harness is processed at different stations and then conveyed to the final crimping station, where it is placed in the arc-shaped recess of the lower crimping head 22. The upper crimping head 21 of the crimping device 2 presses down, causing the sliding block 63 to move downward. This causes the sliding rod 661 to move horizontally under the cooperation of the elastic element 664 and the sliding block 63, withdrawing it directly below the upper crimping head 21 to avoid affecting the crimping action. The movable block 44 first presses the wire harness against the upper mold. As the upper crimping head 21 presses down... This causes the metal part of the crimping terminal to deform, wrapping the exposed core wire of the wire harness. After crimping, the upper crimping head 21 moves upward, and the movable block 44 leaves the wire harness later than the upper mold to avoid the upper crimping head 21 moving upward and affecting the shooting effect of the image acquisition device 7. The sliding rod 661 moves smoothly under the push of the sliding block 63, so that the image acquisition device 7 comes to the top of the lower crimping head 22, acquires the effect image of the wire harness after crimping, analyzes the crimping effect, and marks the defective products.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.

Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
