[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0032] Example 1: See Figure 3-6 As shown, a pin in-place detection device comprises a mounting frame 71, an in-place mounting plate 72, an in-place cylinder 73 and two sets of in-place detection mechanisms, wherein the in-place cylinder 73 is mounted on the mounting frame 71, the in-place mounting plate 72 is slidably mounted on the top of the in-place cylinder 73, and the in-place cylinder 73 drives the in-place mounting plate 72 to move forward and backward on the top of the in-place cylinder 73;

[0033] The in-place detection mechanism includes a contact detection member 74, a displacement sensor 75 and a self-resetting mechanism 76. The contact detection member 74 is slidably disposed on the top of the in-place mounting plate 72, and the moving direction of the contact detection member 74 is parallel to the moving direction of the in-place mounting plate 72.

[0034] The self-resetting mechanism 76 is installed on the front side of the contact detection member 74, and the self-resetting mechanism 76 gives the contact detection member 74 a reset force to move backward;

[0035] The displacement sensor 75 is mounted on the self-resetting mechanism 76 . A displacement detection rod 77 extending forward is disposed on the top of the contact detection member 74 . The middle portion of the displacement detection rod 77 is movably inserted into the displacement sensor 75 .

[0036] In this embodiment, a feeding slide 21 is arranged on the rear side of the in-place detection mechanism, a feeding chamber is arranged in the feeding slide, and a detection clearance groove 213 connected with the feeding chamber is arranged on the front side of the feeding slide 21, and the contact detection member is arranged opposite to the detection clearance groove. When the in-place cylinder output shaft is extended, the contact detection member passes through the detection clearance groove and is inserted into the feeding chamber; when the in-place cylinder output shaft is retracted, the contact detection member moves forward and disengages from the feeding chamber.

[0037] When in use, the pin 1002 is inserted into the housing 1001 of the connector (see the connector structure for details). Figure 1 , 2As shown), the front end of the pin is inside the shell, and it moves to the detection clearance groove, and then the output shaft of the in-place cylinder extends, driving the two sets of in-place detection mechanisms to move backward at the same time, wherein each contact detection piece will face a pin, and when the corresponding contact detection piece contacts the front end of the pin, the output shaft of the in-place cylinder continues to extend until the stroke of the output shaft of the in-place cylinder moves to the right position. Due to the limitation of the pin, the contact detection piece will move forward relative to the in-place mounting plate, and at the same time, it will drive the displacement detection rod to move forward. Since the displacement detection rod moves in the displacement sensor, the displacement distance of the contact detection piece can be detected by the displacement sensor, that is, the distance between the front end of the pin and the front end of the shell can be detected. It will feed back the data to a controller, and then compare it with the preset value in the controller to know whether the insertion distance of the pin is qualified. When the detection is completed, the output shaft of the in-position cylinder retracts, driving the contact in-position mounting plate to move forward. During this process, the in-position detection mechanism also moves forward. During this process, due to the existence of the self-resetting mechanism, when it moves forward, the self-resetting mechanism will also push the contact detection piece to move backward to its original position relative to the in-position mounting plate, so as to facilitate the subsequent detection of the connector pins.

[0038] See also Figure 3-5 As shown, the contact detection member 74 includes an in-position slide 741 and a detection rod 742 installed on the rear side of the in-position slide 741, a longitudinal in-position slide rail 743 is provided on the in-position mounting plate 72 below the in-position slide 741, the bottom of the in-position slide 741 is slidably set on the longitudinal in-position slide rail 743, the detection rod 742 is set parallel to the longitudinal in-position slide rail 743, the self-resetting mechanism 76 is connected to the front end of the in-position slide 741, and the front end of the displacement detection rod 77 is connected to the in-position slide 741.

[0039] The in-position slide plate is directly slidably set on the longitudinal in-position slide rail, and the detection rod at its rear end is used to contact the front end of the pin. The detection rod passes through the detection clearance groove and is inserted into the feeding chamber to contact the front end of the pin to realize the detection of the pin.

[0040] Among them, a connecting screw hole is provided on the rear side of the in-position slide plate 741, and the front end of the detection rod 742 is screwed to the screw hole.

[0041] By setting the connecting screw hole, the screw connection position between the detection rod and the screw hole can be adjusted to adjust the distance between the rear end of the detection rod and the rear end of the in-place slide plate. In this way, if the rear end of the detection rod is worn out after long-term use, it can be quickly adjusted to ensure the detection quality.

[0042] See also Figure 3-6As shown, the self-reset mechanism 76 includes a self-reset housing 761, a reset rod 762 and a reset spring 763. The self-reset housing 761 is mounted on the in-place mounting plate 72. The front end of the reset rod 762 is movably connected to the self-reset housing 761, and the rear end of the reset rod 762 is connected to the front end of the contact detection member 74.

[0043] A reset convex ring 764 is provided in the middle part of the reset rod 762, and the reset convex ring 764 and the reset spring 763 are arranged in the self-reset shell 761. The reset spring 763 is sleeved on the outside of the reset rod 762, and the front end of the reset spring 763 abuts on the front end inner wall of the self-reset shell 761, and the rear end of the reset spring 763 abuts on the front end surface of the reset convex ring 764. The reset spring 763 pushes the reset rod 762 to move backward and causes the contact detection member 74 to move backward.

[0044] The reset rod is pushed backward by the reset spring, so that when the detection rod abuts against the insertion pin and the in-position cylinder continues to push the in-position mounting plate backward, the insertion pin and the detection rod will give resistance to the in-position slide plate, so that the in-position slide plate moves forward relative to the in-position longitudinal slide rail, and the reset rod also moves forward to compress the spring. When the detection is completed and the output shaft of the in-position cylinder retracts, the restoring force of the reset spring will push the reset rod backward and synchronously push the contact detection member backward until the convex ring abuts against the inner wall of the rear end of the self-reset housing, indicating that the reset is in place.

[0045] The displacement sensor is installed on the top of the self-resetting housing, which makes it easy to install and disassemble the displacement sensor.

[0046] Wherein, a guide rail is provided on the top of the in-position cylinder 73, and the guide rail is arranged parallel to the axis of the output shaft of the in-position cylinder;

[0047] The output shaft at the rear end of the in-position cylinder 73 is connected to the in-position mounting plate 72 via a connecting component, and the front end of the connecting component is movably connected to the guide rail.

[0048] The connecting component includes a horizontal plate 78 and a vertical plate 79. The top of the vertical plate 79 is vertically connected to the rear end of the horizontal plate 78. The vertical plate 79 is arranged on the rear side of the in-place cylinder 73. The output shaft at the rear end of the in-place cylinder 73 is connected to the vertical plate 79. The horizontal plate 78 is slidably arranged on the guide rail, and the bottom of the in-place mounting plate 72 is installed on the top of the horizontal plate 78.

[0049] An L-shaped connecting component is adopted, and it is directly slidably set on the top of the positioning cylinder, so that the axial length of the entire pin-in-position detection device can be as short as possible, thereby reducing the space occupied. When it is set in the connector pin assembly equipment, it can reduce the space occupied and facilitate the placement, layout and design of other components of the equipment.
