[0045] The working principle of the terminal insertion depth detection mechanism 100 in this embodiment: During operation, the terminal to be measured 200 reaches a predetermined position under the drive of the manipulator. The telescopic driver 20 drives the detection assembly 40 to move towards the terminal to be measured 200 until the terminal to be measured 200 is inserted into the insertion slot 433. The front end of the terminal to be measured 200 abuts against the limiting block 432. The signal acquisition component 46 drives the front end of the detection main rod 441 to extend into the terminal to be measured 200 by a certain depth. Since the abutting portion 453 of the detection main rod 441 always abuts against the contact portion 4611, at this time, please refer to Figure 2, when it is detected that the front end of the main rod 441 abuts against the wire harness 201 in the terminal 200 to be tested, the signal acquisition component 46 can send an electrical signal, and thus it can be concluded that the wire harness 201 is installed in place and the terminal 200 to be tested is a qualified product; when it is detected that the front end of the main rod 441 does not abut against the wire harness 201 in the terminal 200 to be tested, the signal acquisition component 46 cannot send an electrical signal, and thus it can be concluded that the wire harness 201 is not installed in place and the terminal 200 to be tested is a defective product. The signal acquisition component 46 sends an electrical signal to the main controller of the riveting equipment. After the main controller obtains this electrical signal, it drives the manipulator to clamp the terminal and enter the next process.

[0046] The beneficial effects of the present utility model are as follows: Through the cooperation of the frame 10, the telescopic driver 20, the mounting plate 30 and the detection component 40, it is possible to automatically complete the detection of the insertion depth of the terminal, effectively improve the automation level, improve the production efficiency, reduce the production cost, and at the same time can effectively improve the product qualification rate, improve the product quality, and save unnecessary resource waste.

[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0048] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
