Description

Technical Field

[0001] This utility model relates to the field of automotive sensor wiring harness detection technology, and in particular to an automotive sensor wiring harness positioning and pullback detection device. Background Technology

[0002] Automotive sensor wiring harnesses are an important component of automotive circuitry. They are responsible for connecting various sensors in a vehicle to the electronic control unit (ECU) or other electrical components, ensuring that the sensors can transmit information accurately and promptly. An automotive sensor wiring harness refers to a cable assembly consisting of multiple wires, connectors, and other components used to connect automotive sensors to the ECU or other electrical components.

[0003] Automotive sensor wiring harnesses are prone to malfunctions during use. This is often due to deficiencies in the manual pull-back testing of connections during post-production inspection. Manual pull-back testing cannot guarantee uniform pull-back force, and it can easily damage the connectors. Furthermore, manual sorting of good and defective products can lead to misclassification. Therefore, this invention proposes an automotive sensor wiring harness position pull-back testing device to address these shortcomings. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an automotive sensor wiring harness positioning and pullback detection device. By setting a contour fixing module, a positioning component, and an elastic pin, the socket head of the automotive sensor wiring harness can be stably fixed. The pullback drive cylinder of the pullback detection mechanism can provide a stable and uniform pullback force for the detection process, resulting in high accuracy of wire pullback detection.

[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figure 1-7As shown, this embodiment proposes an automotive sensor wiring harness pull-back detection device, including a pull-back detection workbench 1, a contour fixing module 2, a positioning component 3, a dotting component 4, and a pull-back detection mechanism. The pull-back detection workbench 1 has a base block 5 on its top, and a mounting groove on the base block 5. An elastic pin 6 is located inside the mounting groove. The contour fixing module 2 is located inside the mounting groove above the elastic pin 6. A dotting component 4 is located on one side of the base block 5 inside the mounting groove. A positioning component 3 is located on the rear side of the base block 5 inside the mounting groove. The top of the pull-back detection workbench 1 on the rear side of the base block 5 is... The device includes a support 7, with an outer cover 8 on top of the support 7. Inside the outer cover 8, the top of the support 7 is equipped with a pullback detection mechanism. The pullback detection mechanism includes a pullback drive cylinder 9, a clamping drive cylinder 10, a baffle 11, and a gripper 12. The pullback drive cylinders 9 are symmetrically arranged on the top of the support 7. The output end of the pullback drive cylinder 9 is equipped with a connecting plate 13. The top front end of the connecting plate 13 is equipped with a baffle 11. The top of the connecting plate 13 is equipped with a clamping drive cylinder 10. The output end of the clamping drive cylinder 10 is equipped with a gripper 12. A clamping groove is formed between the front end of the gripper 12 and the front end of the connecting plate 13.

[0023] The automotive sensor wiring harness pullback detection device of this invention performs pullback detection on automotive sensor wiring harnesses by inserting the connector of the automotive sensor wiring harness into the contour fixing module 2 until the connector contacts the elastic pin 6. Then, the elastic pin 6 is further compressed downwards. Next, the positioning component 3 is activated to fix the connector of the automotive sensor wiring harness onto the contour fixing module 2. At this time, the two wires of the automotive sensor wiring harness are respectively inserted into the clamping grooves formed between the front end of the gripper 12 and the front end of the connecting plate 13. Then, the clamping drive cylinder 10 is activated to move the gripper 12. The gripper 12 clamps the wire in the clamping groove. Then, it controls two sets of pull-back drive cylinders 9 to move. One set of pull-back drive cylinders 9 extends and moves all the structures on the connecting plate 13 upward, so that the wire fixed in the clamping groove on one side is pulled upward. After the pull-back test of this set of wires is completed, it resets. The other set of pull-back drive cylinders 9 extends and moves all the structures on the connecting plate 13 upward, so as to realize the pull-back test of the other set of wires. After the pull-back test is completed, the two clamping drive cylinders 10 drive the gripper 12 to reset, and the positioning component 3 also resets, so that the elastic pin 6 resets and pops out the car sensor wiring harness.

[0024] The positioning component 3 includes a positioning cylinder 301 and a positioning plate 302. The positioning cylinder 301 is located inside the rear side of the base block 5, and the positioning plate 302 is located at the output end of the positioning cylinder 301. The positioning plate 302 has a positioning slot 303, which is adapted to the size of the connector of the automotive sensor wiring harness. By activating the positioning cylinder 301, the positioning plate 302 is moved closer to the connector of the automotive sensor wiring harness, so that the connector of the sensor wiring harness is engaged and positioned in the positioning slot 303.

[0025] The dotting assembly 4 includes a dotting cylinder 401 and a dotting needle 402. The dotting cylinder 401 is installed inside one side of the base block 5, and the dotting needle 402 is provided at the output end of the dotting cylinder 401. The tip of the dotting needle 402 points towards the side wall of the socket head of the automotive sensor wiring harness. Qualified automotive sensor wiring harnesses need to be dotted. At this time, the dotting cylinder 401 extends, driving the dotting needle 402 to dot the side wall of the socket head of the automotive sensor wiring harness.

[0026] The connecting plate 13 at the clamping groove location has a groove at its front end, and an infrared sensor 14 is installed in the groove. This application uses the infrared sensor 14 to sense whether the wire is stuck in the clamping groove. Only when the wire is detected stuck can the subsequent start-up pull-back drive cylinder 9 and clamping drive cylinder 10 perform the corresponding operations.

[0027] The outer cover 8 has a first cover plate 15 and a second cover plate 16 at its front end. The first cover plate 15 has an opening 17, and the front ends of the gripper 12 and the connecting plate 13 both extend out of the opening 17.

[0028] The top of the pullback detection workbench 1 inside the rear side of the bottom block 5 is provided with a fixing groove, and a sensing plate 18 is provided in the fixing groove. The sensing plate 18 is used to sense the pullback stroke of the pullback drive cylinder 9. If the pullback drive cylinder 9 fails to drive the wire back to the corresponding stroke distance, an alarm will be triggered (the alarm structure part is the prior art, and this utility model is a public disclosure).

[0029] This invention achieves stable fixation of the automotive sensor wiring harness socket head by setting up a contour fixing module 2, a positioning component 3, and an elastic pin 6. The pull-back drive cylinder 9 of the pull-back detection mechanism provides a stable and uniform pull-back force for the detection process, resulting in high accuracy of wire pull-back detection. The clamping drive cylinder 10, baffle 11, gripper 12, and connecting plate 13 of the pull-back detection mechanism cooperate with each other to achieve stable fixation of multiple wires of the automotive sensor wiring harness and enable separate pull-back detection of multiple wires, which can effectively improve the efficiency of pull-back detection of automotive sensor wiring harnesses.
