[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2 As shown, a locking spring insertion and removal detection mechanism for an automotive connector is characterized by comprising a fixing fixture 1 for positioning the automotive connector to be tested.

[0026] Clamping structure 2 is used to clamp the car connector to be inspected;

[0027] The detection structure 3 includes a pull rod 30 that moves up and down. The pull rod 30 has a pull ring 31 on its outer side that is larger than the inner diameter of the locking spring. The pull rod 30 is connected to a tension tester 32. After the pull rod 30 is inserted into the locking spring of the car connector, the pull ring 31 is located on the lower side of the locking spring.

[0028] The fixing fixture 1 moves to the testing mechanism position under the action of the conveying structure. At this time, the car connector to be tested is fixed by the clamping structure 2. Then, the pull rod 30 of the testing structure 3 is inserted into the lower side of the locking spring of the car connector. Then, the pull rod 30 is controlled to move upward. At this time, the insertion and removal test of the locking spring can be completed by the tensile tester connected to the pull rod 30. By combining the locking spring insertion and removal testing mechanism with the conveying structure of the fixing fixture 1, the insertion and removal test can be automated, thereby improving production efficiency.

[0029] During the testing process using the tensile testing instrument 32, it is necessary to test the upward pulling force of the pull rod 30. Therefore, in this embodiment, the pull rod 30 is connected to the tensile testing instrument via a first vertical moving structure. The first vertical moving structure includes a first cylinder 33, and the pull rod 30 is fixed to the piston rod of the first cylinder 33. The cylinder body of the first cylinder 33 is fixed to the moving end of the tensile testing instrument. In the initial state, the piston rod of the first cylinder 33 extends a certain distance, causing the pull rod 30 to insert into the locking spring of the automotive connector. At this time, the force when the pull ring 31 of the pull rod 30 is inserted can be tested during the tensile test. When the piston rod of the first cylinder 33 retracts, the pull rod 30 moves upward. As the pull rod 30 moves upward, the pull ring 31 on the outside of the pull rod 30 abuts against the locking spring. As the pull rod 30 continues to move upward, the pull-out force can be tested, thus completing the testing process.

[0030] At this time, the fixed fixture 1 is used to place the car connector to be inspected and moves on the conveyor structure, which is a conveyor belt. Several fixed fixtures 1 are provided on the conveyor belt to realize the movement of the fixed fixtures 1. When it moves to the position of the inspection mechanism, the conveyor belt stops moving to realize the inspection of the car connector. After the inspection is completed, the conveyor belt moves so that the next fixed fixture 1 moves to the position under the inspection structure 3, thereby realizing automated inspection.

[0031] The first cylinder 33 mainly controls the up-and-down movement of the pull rod 30, but its stroke may be insufficient. Therefore, in this embodiment, the locking spring insertion / removal detection mechanism also includes a second vertical moving structure. The second vertical moving structure includes a vertical plate 41, and a moving plate 42 is connected to the side of the vertical plate 41 via a guide rail slider. A second cylinder 43 is provided on the upper side of the vertical plate 41, and the piston rod of the second cylinder 43 is fixed to the moving plate 42 to control the up-and-down movement of the moving plate 42. At this time, the detection structure 3 is set on the side of the moving plate 42. Under the action of the second cylinder 43, the moving plate 42 moves up and down, thereby causing the detection structure 3 to move up and down as a whole. This increases the range of movement of the pull rod 30, thus adapting to different needs.

[0032] During use, the tensile tester is fixed relative to the moving plate 42. Therefore, in this embodiment, an upper fixing plate 34 is provided on the side of the moving plate 42, and the tensile tester is fixed on the upper side of the upper fixing plate 34. The upper fixing plate 34 is provided with an upper through hole, through which the moving end of the tensile tester passes and is fixed to the cylinder body of the first cylinder 33. In this way, under the action of the upper fixing plate 34, the tensile tester can be fixed on the outside of the moving plate 42 and move up and down under the action of the first cylinder 33.

[0033] Meanwhile, a lower fixing plate 35 is also fixed to the side of the movable plate 42. The fixing fixture 1 is located below the lower fixing plate 35. The lower fixing plate 35 has an opening, and the pull rod 30 passes through the lower fixing plate 35 from the opening to the fixing fixture 1 on the lower side. At this time, the clamping structure 2 is fixed to the upper side of the lower fixing plate 35.

[0034] Specifically, the clamping structure 2 includes a clamping cylinder 21, which is a finger cylinder. Two piston rods of the clamping cylinder 21 are connected to grippers 22. The lower fixing plate 35 has through holes, and the lower side of the grippers 22 passes through these through holes to the fixing fixture 1. Under the action of the clamping structure 2, the car connector to be tested can be fixed, preventing it from being pulled off the fixing fixture 1 during the upward movement of the pull rod 30, thus affecting the accuracy of the testing structure 3.

[0035] Furthermore, to ensure that the gripper 22 remains horizontal during movement, in this embodiment, a guide block 23 is provided on the upper side of the lower fixing plate 35. The guide block 23 has a guide groove 231 with a transverse hole. A moving block 232 that moves along the direction of the guide groove 231 is provided within the guide groove 231. The gripper 22 is connected to the piston rod of the finger cylinder through the moving block 232. Under the action of the guide groove 231, the gripper 22 can move along the direction of the guide groove 231 to clamp the car connector.

[0036] Finally, the pull rod 30 has an annular groove on its outer side, and the pull ring 31 is a silicone ring. The pull ring 31 is snapped into the annular groove, and the annular groove secures the pull ring 31. At the same time, silicone is used as the pull ring 31, so that the locking spring will not be damaged during use.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
