DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0030] The following is combined with Figure 1-5 The utility model is described in further detail.

[0031] Reference Figure 1-3 A wiring harness terminal detection device includes: a machine platform 1, on which is provided a terminal base 2, a wiring harness connection end limiting mechanism 3, a first drive mechanism, and a sensor assembly; a terminal slot 21 is provided at the top of the terminal base 2, and during detection, the terminal portion of the product is placed in the terminal slot 21 so that the movement of the terminal is restricted during detection;

[0032] In order to limit the wiring harness connection end of the product, the wiring harness connection end limiting mechanism 3 includes a cover plate 31, a baffle 32 arranged on one side of the cover plate 31, and a second driving component 33. When the terminal portion of the product is placed in the terminal slot 21, the second driving component 33 drives the cover plate 31 and the baffle 32 to drive the cover plate 31 close to the wiring harness connection end at the terminal slot 21 until the cover plate 31 moves to the top of the wiring harness connection end at the terminal slot 21, and the baffle 32 is placed on one side of the wiring harness connection end;

[0033] After the terminal part and the wiring harness connection end part of the product are respectively restricted, the baffle 32 is driven by the first driving mechanism to approach the wiring harness connection end at the terminal groove 21 from the horizontal direction, and a fixed thrust is applied to the wiring harness connection end. The pressure sensor of the sensor assembly detects the magnitude of the thrust applied by the first driving mechanism to the baffle 32 (wiring harness connection end). When the detected product is a qualified product, the wiring harness connection end and the terminal will not be relatively displaced, and the maximum thrust value detected by the pressure sensor is a fixed value (the positions of the pressure sensor and the wiring harness connection end have not changed, so the pressure value detected by the pressure sensor is constant). When the detected product is unqualified, the welding position is broken, the wiring harness connection end and the terminal are relatively displaced, and the baffle 32 is displaced, so that the pressure detected by the pressure sensor becomes smaller. The pressure value detected by the pressure sensor is less than the pressure value detected when the product is qualified, indicating that the product is a defective product, thereby completing the detection of the product welding condition. Moreover, since the thrust applied to the wiring harness connection end is a fixed value, the qualified product will not be damaged and can continue to be used, reducing losses.

[0034] Reference Figure 3-4 In order to realize the driving of the wiring harness connection end limiting mechanism 3, the wiring harness first driving mechanism includes a slide 6, a screw 7 and a power assembly. The slide 6 is slidably set on the machine 1, and the screw 7 is rotatably set on the machine 1. The screw 7 is threadedly connected to the slide 6. The power assembly is used to drive the screw 7 to rotate. The wiring harness connection end limiting mechanism 3 is set on the slide 6 (the pressure sensor can be set on the side of the baffle 32 away from the first driving mechanism, or it can be set between the baffle 32 and the first driving mechanism to meet the detection of the pressure applied to the wiring harness connection end by the baffle 32). When the thrust of the first driving mechanism acts on the wiring harness connection end, pressure is applied to the pressure sensor. In this way, the screw 7 is driven to rotate by the power assembly, so that the slide 6 threadedly connected to the screw 7 moves toward the axial direction of the screw 7, thereby completing the driving of the baffle 3, and two parallel slide rails 8 are provided on the machine 1, and the slide 6 is clamped on the two slide rails 8. In this way, it is ensured that the slide 6 moves along the required route.

[0035] Reference Figure 2-4The second driving assembly 33 is used to drive the flap 34 to rotate. In this way, the flap 34 is driven by the second driving assembly 33 to rotate, so that the cover plate 31 makes a circular motion until the cover plate 31 covers the wiring harness connection end (the wiring harness connection end is in the path of the circular motion). After the detection is completed, the second driving assembly 33 drives the flap 34 to reverse, so that the cover plate 31 is away from the wiring harness connection end. In order to drive the flap 34 to rotate, the second driving assembly 33 can be a cylinder, which is horizontally arranged on the slide 6. The output end of the cylinder is rotatably connected to the flap 34. The rotation direction of the flap 34 relative to the cylinder is consistent with the rotation direction of the flap 34 relative to the slide 6. During detection, the flap 34 is in a horizontal state.

[0036] Further optimization is, Figure 3 As shown, in order to ensure the stability of the wiring harness connection end limiting mechanism 3 during detection, a supporting seat 5 is provided on the slide 6. When the cover 31 moves to the top of the wiring harness connection end at the terminal slot 21, the flap 34 is placed on the supporting seat 5. In this way, the flap 34 is supported by the supporting seat 5 to prevent the angle of the flap 34 from changing during the detection process.

[0037] like Figure 3 and 5 As shown, the machine 1 is provided with a fixing seat 4 on one side of the terminal seat 2, and a card slot is provided on one side of the fixing seat 4. A card plate 22 adapted to the card slot is provided on one side of the terminal seat 2. The position of the terminal seat 2 is positioned by cooperating with the card slot and the card plate 22, which is convenient for installation and replacement, and a threaded hole 23 is provided on the terminal seat 2, and the terminal seat 2 can be fixed to the machine 1 by bolts.

[0038] A further optimization is that in order to avoid interference with the detection and for safety reasons, a casing 9 is provided on the machine 1, and a product entry and exit operation window 91 is provided on the casing 9. In this way, the casing 9 improves the sealing of the device, and the product is taken and placed through the product entry and exit window 91, and a control panel 92 is provided on the casing 9, and the device is controlled by the control panel 92.

[0039] In summary, the baffle 32 is driven by the first driving mechanism to approach the wiring harness connection end at the terminal slot 21 from the horizontal direction, and a thrust is applied to the wiring harness connection end. The pressure sensor of the sensor assembly is used to detect the magnitude of the thrust applied by the first driving mechanism to the baffle 32. When the detected product is a qualified product, the wiring harness connection end and the terminal will not be relatively displaced. The maximum thrust value detected by the pressure sensor is a fixed value. When the detected product is unqualified, the welding position is broken, and the wiring harness connection end and the terminal are relatively displaced (a gap is generated between the wiring harness connection end and the baffle 32). At this time, the pressure value detected by the pressure sensor is less than the pressure value detected when the product is qualified, indicating that the product is a defective product, thereby completing the detection of the product welding condition. Moreover, since the thrust applied to the wiring harness connection end is a fixed value, the qualified product will not be damaged and can continue to be used, thereby reducing losses.

[0040] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
