Referring to fig. 4, 5 and 6, the positioning mechanism 40 includes the positioning top block 41, the first ejector rod 42 and the supporting block 43. One end of the first ejector rod 42 abuts against the positioning ejector block 41, and the other end is connected to the abutting block 43.

Specifically, the positioning top block 41 is disposed at the center of the bottom plate 10, and extends toward the direction approaching the cover plate 20 for another preset distance. When the product 300 is provided on the workpiece assembling device 100, the cover plate 20 is pressed down toward the product 300, and the distance by which the positioning top block 41 is pressed down is the height difference H. At this time, the upper end of the positioning jack 41 is flush with the upper end of the support block 30, and the positioning jack 41 is not moved downward any more.

In one embodiment, the height difference H is 6mm, and it is understood that in other embodiments, the height difference H may be 2mm, 3mm, 4mm, 5mm, 7mm, 8mm, 9mm, or 10mm, and further, the value of the height difference H is not limited thereto, and may be replaced according to specific needs.

The first ejector rod 42 is embedded in the bottom plate 10, and the first ejector rod 42 and the positioning ejector block 41 are abutted through an inclined plane P.

The fourth elastic member 5444 is configured to provide an elastic force to the second clamping block 5442, so that the fourth elastic member 5444 can provide a force to clamp the workpiece 200 by the second clamping block 5442 when the second clamping block 5442 and the second fixing block 5441 are gradually separated.

The two second clamping blocks 5442 are vertically arranged to fix different surfaces of the workpiece 200, and it is understood that in other embodiments, only one second clamping block 5442 may be provided, and the second clamping block 5442 may be L-shaped to fix different surfaces of the workpiece 200.

Specifically, the second assembly 54 operates such that, when the push-pull rod 51 is operated to be located at the first station, the second ejector 52 moves toward the clamping groove 511 until the end of the second ejector 52 extends into the clamping groove 511. At this time, the second ejector rod 52 is close to the end of the second connection block 542, the inclined plane P of the end is gradually separated from the inclined plane P on the second connection block 542, the second ejector rod 52 unlocks the second connection block 542, the third elastic member 543 drives the second connection block 542 to move upwards, and at the same time, the second connection block 542 drives the second clamping block 5442 to move upwards. In the process of moving the second clamping block 5442 upwards, the inclined plane P on the second clamping block 5442 is gradually separated from the inclined plane P on the second fixing block 5441, and the fourth elastic member 5444 provides an elastic force to the second clamping block 5442, so that the second clamping block 5442 and the second connecting block 542 clamp the workpiece 200 until the third elastic member 543 is not moved upwards any more, and the workpiece 200 is assembled on the product 300.

When the push-pull rod 51 is operated to be located at the second station, the second ejector rod 52 moves away from the clamping groove 511 until the end of the second ejector rod 52 is separated from the clamping groove 511 and abuts against the side wall of the push-pull rod 51. At this time, the second ejector rod 52 is close to the end of the second connection block 542, the inclined plane P of the end gradually abuts against the inclined plane P on the second connection block 542, the second ejector rod 52 gradually fixes the second connection block 542, the third elastic member 543 is compressed by the second connection block 542, and the second connection block 542 drives the second clamping block 5442 to move downward. In the process of moving the second clamping block 5442 downward, the inclined plane P on the second clamping block 5442 gradually abuts against the inclined plane P on the second fixing block 5441, and the fourth elastic member 5444 is also gradually compressed, so that a gap is generated between the second clamping block 5442 and the second connecting block 542, so that the workpiece 200 can be placed until the end portion of the second ejector rod 52 abuts against the side wall of the push-pull rod 51, and the second assembly 54 is re-fixed.

Similarly, when another work 200 is assembled, the work 200 is placed between the second clamp block 5442 and the second connection block 542, and the above steps may be repeated. The second component 54 operates in the same manner as the first component 53. The difference is that the first component 53 is one of the first clamping blocks 5342, and the second component 54 includes two of the second clamping blocks 5442.

In one embodiment, the first elastic member 533, the second elastic member 5344, the third elastic member 543 and the fourth elastic member 5444 are springs, and it is understood that in other implementations, other structures with equivalent functions or actions may be substituted.
