Technical Field

[0001] The utility model relates to the technical field of automobile component detection, in particular to a signal pin detection structure. Background Art

[0002] During the assembly process of the steering gear electronic control unit, it is necessary to ensure that the height of the signal pin passing through the upper shell after the upper shell is installed meets the product design requirements, and it is necessary to ensure that the signal pin will not retreat during the normal plugging process when the customer plugs in the wiring harness, so the assembled signal pin needs to be tested.

[0003] At present, conventional signal pin detection is carried out in steps. First, the extension height of the pin is detected, and then the retraction status of the pin is manually detected. This requires more personnel and space, and the detection efficiency is low.

[0004] Therefore, it is necessary to design a signal pin detection structure that can simultaneously detect the extension height and anti-pin withdrawal ability of the pin, improve the detection efficiency, and reduce the requirements for personnel and space. Summary of the invention

[0023] The utility model is now further described with reference to the accompanying drawings.

[0024] See also Figure 1 , Figure 2The utility model is a signal pin detection structure, including an upper substrate, a lower substrate, a mounting seat, a detection probe, a spring, a hole plate, a connecting plate, and a positioning pin. An upper substrate 6 is installed above the lower substrate 12, a through hole 121 is provided in the center of the lower substrate 12, a positioning pin 4 is installed at the bottom of the lower substrate 12, a mounting seat 11 is installed in the bottom center of the upper substrate 6, a detection probe 8 is vertically installed inside the mounting seat 11, and the lower end of the detection probe 8 is exposed from the bottom of the mounting seat 11, a hole plate 9 and a connecting plate 13 are installed in the top center of the upper substrate 6, the hole plate 9 is located above the connecting plate 13, the upper end of the detection probe 8 passes through the connecting plate 13 and the hole plate 9, a spring 7 is provided on the outer sleeve of the detection probe 8, one end of the spring 7 is fixed to the detection probe 8, and the other end of the spring 7 is against the connecting plate 13.

[0025] A connecting rod 5 is installed between the lower substrate 12 and the upper substrate 6 to support the upper substrate 6 .

[0026] A lifting mechanism 16 is installed below the lower substrate 12. A product tray 15 is placed on the supporting surface of the lifting mechanism 16. The product to be tested is placed on the product tray 15. The positioning pins 4 correspond to the positioning holes of the product tray 15. Preferably, the lifting mechanism 16 is a cylinder.

[0027] The lifting mechanism 16 lifts the product to be tested on the product tray 15 into place. After the positioning pin 4 is inserted into the positioning hole of the product tray 15, the pin 18 or the shell 17 of the product to be tested abuts against the lower end of the detection probe 8, and the upper end of the detection probe 8 is exposed from the top of the orifice plate 9, and the exposed part is used for subsequent detection.

[0028] The height detection of the upper end of the detection probe 8 can be performed manually or automatically. For example, if an automatic method is used, a height detection camera 14 is installed above the orifice plate 9 to perform detection.

[0029] See also Figure 5 The detection probe 8 includes a pin detection probe 81 and a shell detection probe 82. The setting position of the shell detection probe 82 matches the position of the shell 17 of the product to be tested, and the setting position of the pin detection probe 81 matches the position of the pin 18 of the product to be tested.

[0030] The top of the upper substrate 6 is provided with a positioning pin hole 1 and a quick locking screw 2 to achieve quick installation of the detection structure and the equipment, so as to facilitate quick replacement of the detection structure according to the model of the product to be tested.

[0031] Handles 10 are provided on both sides of the top of the upper substrate 6 to facilitate carrying the detection structure.

[0032] The upper substrate 6 is mounted with an RFID tag 3 to prevent the detection structure used from not matching the model of the product to be detected.

[0033] See also Figure 3 , Figure 4 , after the product to be tested moves to the top of the lifting mechanism 16 along with the product tray 15, the lifting mechanism 16 lifts the product tray 15, and the positioning pin 4 is inserted into the positioning hole of the product tray 15 to accurately position the tray and the product, and the lifting mechanism 16 is stopped as a mechanical limit. At this time, the product to be tested passes through the through hole 121, and the shell 17 of the product to be tested and the pin 18 surrounded by the shell 17 respectively press the shell detection probe 82 and the pin detection probe 81 upward, and the shell detection probe 82 and the pin detection probe 81 move upward to generate a height difference, which is measured by the height detection camera 14 or manually, so as to obtain the protruding height of the pin 18 of the product to be tested.

[0034] Since the pin detection probe 81 compresses the spring 7 to generate a reverse thrust, each pin detection probe 81 will generate a force of about 10N on the corresponding pin 18, thereby detecting the anti-retraction ability of the pin 18. If the anti-retraction ability of the pin 18 is insufficient, it will be squeezed back by the pin detection probe 81, which will also cause the height detection of the pin 18 to fail.

[0035] See also Figure 6 , the extended height H of the pin to be detected is the vertical distance between the tip of the pin 18 and the upper edge of the shell 17, H=(ba)-d, where a is the length of the shell detection probe 82, b is the length of the pin detection probe 81, and d is the measured height difference between the pin detection probe 81 and the shell detection probe 82. a and b are fixed values, which are input to the height detection camera 14 or manual as fixed compensation values ​​(ba). After the height detection camera 14 or manual recognizes the height difference d, it can directly output the extended height H of the pin to be detected, and compare it with the specified value, so as to synchronously determine whether the product to be tested is qualified.

[0036] The utility model designs a signal pin detection structure, which completes the detection of the extension height and the anti-pin withdrawal ability of the pin in one detection process, improves the detection efficiency, reduces the requirements for personnel and space, and optimizes the production rhythm of the steering machine.
