Description
Technical Field
[0001] This utility model relates to the technical field of wire harness testing equipment, and in particular to a quality control and testing equipment for large-scale production of automotive wire harnesses. Background Technology
[0002] In the mass production of automotive wiring harnesses, traditional testing methods have significant limitations: On the one hand, traditional testing relies heavily on manual visual inspection or single-position testing methods, making it difficult to achieve a comprehensive scan of all parts of the wiring harness. Moreover, manual testing is inefficient, highly subjective, and prone to missed or false detections. On the other hand, due to the significant differences in length and structure of wiring harnesses for different car models and functions, existing testing equipment often struggles to flexibly adjust the clamping spacing to accommodate diverse specifications of wiring harnesses. This often requires replacing specialized fixtures or adjusting equipment parameters, which is not only cumbersome and time-consuming but also prone to unstable clamping of the wiring harness due to improper spacing adjustment, affecting testing accuracy. Therefore, we have introduced a new quality control and testing equipment for the mass production of automotive wiring harnesses. Utility Model Content
[0003] The main purpose of this invention is to provide a quality control and testing device for large-scale production of automotive wiring harnesses, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A quality control and testing device for large-scale production of automotive wiring harnesses includes a testing platform. The upper left and upper right sides of the testing platform are each equipped with a sliding groove. Electric push rods are fixedly installed through the walls of both sliding grooves. Support plates are fixedly installed at the output ends of both electric push rods via sliders. An installation adjustment assembly is movably installed between the two support plates. A display is fixedly installed at the front right end of the right support plate. A buzzer and indicator light are located at the lower front of the display. A mounting groove is located at the rear upper end of the testing platform. Guide grooves are provided on the upper front and upper rear inner walls of the mounting groove. A testing mechanism is installed inside the mounting groove.
[0005] Preferably, the installation adjustment assembly includes two circular shells, which are arranged in a left-right correspondence. A rotating shaft is jointly provided at the middle of the left end of each of the two circular shells through a through hole. The left part of the rotating shaft passes through the right end of the left support plate and extends to the left side of the support plate. A first motor is fixedly installed at the left end of the rotating shaft. A drive gear is fixedly installed on both the left and right sides of the outer surface of the rotating shaft. Two drive gears are located on the inner surfaces of the two circular shells respectively. Four driven gears are meshed with the outer surfaces of the two drive gears. Rotating rods are fixedly installed at the middle of the left ends of the eight driven gears. Several first racks are provided on the inner surfaces of the two circular shells. The four rotating rods on the left and four on the right respectively pass through the inner walls of the two circular shells and extend between them. Fixing clips are provided on the facing surfaces of the four rotating rods on the left and four on the right. An automotive wiring harness body is jointly provided between the two corresponding fixing clips on the left and right sides.
[0006] Preferably, the first motor is fixedly mounted on the left end of the left support plate, and the right end of the rotating shaft is rotatably connected to the left end of the right support plate through a bearing.
[0007] By adopting the above technical solution, the first motor can be stably fixed and the rotating shaft can be reliably supported.
[0008] Preferably, the driven gear is connected to the support plate by meshing through a bearing, and the plurality of first racks are distributed in an equally spaced ring array.
[0009] By adopting the above technical solution: the bearing connection allows the driven gear to rotate flexibly relative to the support plate, while the first rack of the equidistant ring array can ensure uniform and stable meshing with the driven gear, thus guaranteeing the consistency and stability of power transmission.
[0010] Preferably, the four adjacent driven gears are arranged in an equidistant circular array, and the outer surfaces of the four adjacent driven gears are meshed and connected with several first racks.
[0011] By adopting the above technical solution, the driven gears of the equidistant ring array form a symmetrical meshing structure with the first rack, which can realize the synchronous drive of multiple gears.
[0012] Preferably, the detection mechanism includes a U-shaped frame and a cross frame, which are arranged vertically in correspondence. The upper end of the cross frame is provided with several second racks. The rear end of the U-shaped frame is fixedly installed with a second motor. The output end of the second motor is fixedly installed with a pinion via a drive rod. The upper end of the U-shaped frame is fixedly installed with an L-shaped support. The front part of the L-shaped support extends to the top of the automotive wiring harness body. The lower front and lower rear parts of the L-shaped support are provided with L-shaped plates. An industrial camera is detachably installed between the two L-shaped plates.
[0013] By adopting the above technical solution, the second motor can drive the U-shaped frame to move as a whole through the cooperation of the pinion and the second rack, thereby realizing the position adjustment of the industrial camera.
[0014] Preferably, the outer surface of the pinion is meshed with the second rack.
[0015] By adopting the above technical solution, the rotational motion of the motor is converted into the linear motion of the U-shaped frame by utilizing the meshing characteristics of gears and racks, thereby driving the industrial camera to move smoothly.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The electric push rod in the slide groove of the testing table can drive the two support plates to move synchronously along the slide groove through the slider. The spacing can be precisely adjusted according to the length of the wire harness to adapt to different specifications of wire harnesses. When the operator places the automotive wire harness body between the fixed clamps, the first motor drives the rotating shaft and the drive gear to rotate at the same time. The drive gear meshes with the driven gear, and the driven gear rolls along the first rack in the circular shell, driving the rotating rod and the fixed clamp to adjust the angle synchronously, realizing the multi-directional rotation of the wire harness, ensuring that all parts of the wire harness can be within the inspection field of view, which is convenient for simultaneous inspection of multiple wire harnesses. 2. After clamping and fixing, the second motor in the detection mechanism drives the pinion to rotate. The pinion meshes with the second rack on the crossbeam, causing the U-shaped frame to move smoothly along the crossbeam and guide groove. This allows the industrial camera to flexibly adjust its position above the automotive wiring harness body, enabling comprehensive scanning and detection. The detachable design of the L-shaped plate also facilitates the maintenance and replacement of the industrial camera. The industrial camera transmits images to the display. If a quality problem is detected, the buzzer will sound an alarm and the indicator light will illuminate. By combining visual inspection with audible and visual alarms, problems can be quickly identified and responded to, effectively improving detection efficiency and stability, and ensuring timely screening of unqualified products.

[0022] Please see Figure 1-4 This utility model provides a technical solution: The quality control and testing equipment for large-scale production of automotive wiring harnesses includes a testing platform 1. The upper left and upper right sides of the testing platform 1 are each equipped with a sliding groove 10. Electric push rods 11 are fixedly installed through the walls of both sliding grooves 10. Support plates 2 are fixedly installed at the output ends of both electric push rods 11 via sliders. An installation adjustment assembly 3 is movably installed between the two support plates 2. A display 4 is fixedly installed at the front right end of the right support plate 2. A buzzer 5 and an indicator light 6 are located at the lower front end of the display 4. A mounting groove 7 is located at the rear upper end of the testing platform 1. Guide grooves 8 are located on the upper front and upper rear inner walls of the mounting groove 7. A testing mechanism 9 is located inside the mounting groove 7.
[0023] In this embodiment, the installation adjustment assembly 3 includes two circular shells 31, which are arranged in a left-right correspondence. A rotating shaft 32 is jointly provided at the center of the left end of each of the two circular shells 31 through a through hole. The left part of the rotating shaft 32 passes through the right end of the left support plate 2 and extends to the left side of the support plate 2. A first motor 33 is fixedly installed at the left end of the rotating shaft 32. A drive gear 34 is fixedly installed on both the left and right sides of the outer surface of the rotating shaft 32. The two drive gears 34 are located on the inner surfaces of the two circular shells 31, respectively. Four driven gears 35 are meshed with the outer surfaces of the two drive gears 34. A rotating rod 36 is fixedly installed through the center of the left end of each of the eight driven gears 35. Several first racks 37 are provided on the inner surfaces of the two circular shells 31, located on the left side. The four rotating rods 36 on the left and right sides respectively penetrate the inner walls of the two circular shells 31 and extend between the two circular shells 31. The four rotating rods 36 on the left and the four rotating rods 36 on the right are all provided with fixing clips 38 facing each other. The automotive wiring harness body 39 is provided between the two corresponding fixing clips 38 on the left and right sides. The first motor 33 is fixedly installed on the left end of the support plate 2 on the left side. The right end of the rotating shaft 32 is rotatably connected to the left end of the support plate 2 on the right side through a bearing. The driven gear 35 is meshed with the support plate 2 through a bearing. Several first racks 37 are distributed in an equally spaced ring array. The four adjacent driven gears 35 are distributed in an equally spaced ring array. The outer surfaces of the four adjacent driven gears 35 are meshed with several first racks 37.
[0024] Through the above scheme: the first motor 33 starts and drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the two left and right drive gears 34 to rotate synchronously. Since the drive gears 34 mesh with four driven gears 35, and the driven gears 35 are mounted on the support plate 2 through bearings and mesh with the first rack 37, which is distributed in an equal-distance ring array inside the circular shell 31, and the four adjacent driven gears 35 are also distributed in an equal-distance ring array, when the drive gears 34 rotate, they drive the four driven gears 35 to roll along the first rack 37, thereby driving the rotating rod 36 to rotate. Finally, the corresponding left and right fixing clamps 38 adjust their angles synchronously, realizing multi-directional clamping and angle adjustment of the automotive wiring harness body 39. The rotating shaft 32 is connected to the right support plate 2 through bearings, and together with the left support plate 2 to fix the first motor 33, the overall rotation stability is ensured.
[0025] In this embodiment, the detection mechanism 9 includes a U-shaped frame 90 and a cross frame 91, which are arranged vertically in correspondence. The upper end of the cross frame 91 is provided with several second racks 92. The rear end of the U-shaped frame 90 is fixedly installed with a second motor 94. The output end of the second motor 94 is fixedly installed with a pinion 93 via a drive rod. The upper end of the U-shaped frame 90 is fixedly installed with an L-shaped support 95. The front part of the L-shaped support 95 extends above the automotive wiring harness body 39. The lower front and lower rear parts of the L-shaped support 95 are provided with L-shaped plates 96. An industrial camera 97 is detachably installed between the two L-shaped plates 96. The outer surface of the pinion 93 is meshed with the second racks 92.
[0026] With the above scheme: During testing, the second motor 94 starts and drives the pinion 93 to rotate via the drive rod. Because the pinion 93 meshes with the second rack 92 on the cross frame 91, the U-shaped frame 90 moves smoothly along the cross frame 91. The U-shaped frame 90 drives the L-shaped support 95 and the industrial camera 97 mounted below via the L-shaped plate 96 to move synchronously, allowing the industrial camera 97 to adjust its testing position above the automotive wiring harness body 39, thereby performing a comprehensive test on the automotive wiring harness body 39 held by the fixing clamp 38.
[0027] It should be noted that this utility model is a quality control and testing equipment for large-scale production of automotive wiring harnesses. During use, the operator places the automotive wiring harness body 39 between the corresponding left and right clamps 38 in the installation and adjustment assembly 3. Based on the wiring harness length, the electric push rods 11 in the two slide grooves 10 on the testing table 1 are activated, driving the two support plates 2 to move synchronously along the slide grooves 10 via the slider, adjusting the spacing to match the wiring harness length. Then, the wiring harnesses to be tested are placed in their respective clamps 38. Next, the first motor 33 is activated, driving the rotating shaft 32 to rotate. 2. The two driving gears 34 rotate synchronously. Because the driving gears 34 mesh with four driven gears 35, and the driven gears 35 are mounted on the support plate 2 via bearings and mesh with the first rack 37 arranged in an equidistant ring within the circular shell 31, and the four adjacent driven gears 35 are also arranged in an equidistant ring, the rotation of the driving gears 34 drives the four driven gears 35 to roll along the first rack 37, thereby driving the rotating rod 36 to rotate. Ultimately, this causes the corresponding left and right fixing clamps 38 to adjust their angles synchronously, achieving multi-directional and multi-angle adjustment of the wire harness and ensuring the proper functioning of each part of the wire harness. All parts are within the detection field of view. After clamping and fixing, the detection mechanism 9 starts working. The second motor 94 starts and drives the pinion 93 to rotate through the drive rod. Because the pinion 93 meshes with the second rack 92 on the cross frame 91, the U-shaped frame 90 moves smoothly along the cross frame 91. At the same time, the U-shaped frame 90 slides along the guide groove 8 in the mounting groove 7 to further improve the stability of the movement. The U-shaped frame 90 drives the L-shaped support 95 and the industrial camera 97 mounted below through the L-shaped plate 96 to move synchronously, so that the industrial camera 97 can flexibly adjust the detection position above the automotive wiring harness body 39. This system enables comprehensive scanning and inspection of the entire wire harness. The detachable design of the L-shaped plate 96 facilitates the maintenance and replacement of the industrial camera 97. The industrial camera 97 transmits the detected image information to the display 4, which displays the inspection results in real time. If a quality problem is detected in the wire harness, the buzzer 5 immediately sounds an alarm and the indicator light 6 illuminates, promptly alerting the operator. By combining visual inspection with audible and visual alarms, rapid identification and response to quality problems are achieved, effectively improving the efficiency and stability of wire harness quality inspection in large-scale production and ensuring that unqualified products are promptly screened out.
