[0024] In combination Figures 6-9 As shown in the drawings, the top surface of the main slider 9 and the top surface of the auxiliary slider 12 are integrally formed with a T-shaped connector 22, the bottom surface of the object table 5 is provided with a T-shaped slot which is in sliding cooperation with the connector 22, the connector 22 is elastically connected with a clamping block 17, and the inner wall of the T-shaped slot is uniformly provided with a plurality of clamping slots 18 which are in cooperation with the clamping block 17, the bottom surface of the main slider 9 and the bottom surface of the auxiliary slider 12 are slidingly assembled with a pull plate 19, the top surface of the pull plate 19 is fixedly provided with a vertical rod, the vertical rod is slidable relative to the main slider 9, the auxiliary slider 12 and the connector 22, and the vertical rod is provided with a plurality of clamping blocks 17 which are in cooperation with the clamping slots 18. Figure 9 As can be seen, the clamping block 17 is provided with a through slot for the vertical rod to pass through, a protrusion 1701 is fixedly arranged at the inner side wall of the through slot which is away from the clamping slot 18, a pressing block 16 is fixedly arranged on the vertical rod and is in cooperation with the protrusion 1701, the pressing block 16 is located on the top of the protrusion 1701 and the side of the pressing block 16 which is close to the protrusion 1701 is provided with an inclined pressing surface 1601, two housings 13 are fixedly installed on the material rack 2, in the initial state, the main slider 9 and the auxiliary slider 12 are respectively located above the two housings 13, an electromagnet 20 is fixedly installed in the housing 13, the pull plate 19 which is slidingly arranged at the bottom of the main slider 9 or the auxiliary slider 12 is made of iron and can be attracted by the electromagnet 20 to move downward.
[0025] In actual use, the driving assembly outside drives the object table 5 to roll along the main slide rail 201. When the parts on the object table 5 begin to pass through the detection unit 21, the electromagnet 20 below the main slide block 9 can be powered to move the pull plate 19 at the main slide block 9 downward, so that the pressure of the pressing block 16 on the protruding block 1701 can extrude the clamping block 17. When the clamping block 17 is inserted into the clamping groove 18, the main slide block 9 can be locked with the object table 5 and move synchronously with the object table 5. During the whole process, the connecting rope 11 between the main slide block 9 and the auxiliary slide block 12 will continue to be stretched, and the pressure of the pressing rod 601 on the connecting rope 11 makes the pressing rod 601 tend to move the sliding sleeve 602 to the midpoint of the connecting rope 11. When the parts on the top of the object table 5 completely pass through the detection unit 21, the electromagnet 20 at the auxiliary slide block 12 can promote the clamping between the auxiliary slide block 12 and the object table 5. At this time, the main slide block 9 and the auxiliary slide block 12 are both locked with the object table 5, and the connecting rope 11 also stops stretching. Since the connecting rope 11 is bent downward, the pressure between the pressing rod 601 and the connecting rope 11 can promote the sliding sleeve 602 to move to the midpoint of the connecting rope 11, and the pressure of the sliding sleeve 602 on the telescopic rod 15 can promote the end of the telescopic rod 15 away from the sliding sleeve 602 to extend out of the object table 5. Subsequently, when the object table 5 enters the cavity 1, the extended telescopic rod 15 is aligned with the positioning groove 103, and the end of the telescopic rod 15 can be inserted into the positioning groove 103, thereby locking the object table 5 in the cavity 1, and the parts on the object table 5 are at the center position of the upper electrode plate 4 and the lower electrode plate 3, thereby facilitating the activation of the surface of the parts.
[0026] In summary, the device cooperates the pressing rod 601 with the connecting rope 11. By the bending shape of the connecting rope 11 and the pressure of the pressing rod 601 on the connecting rope 11, the pressing rod 601 can drive the sliding sleeve 602 to move to the midpoint of the connecting rope 11, thereby marking the center line of the parts stacked on the object table 5. After the object table 5 moves into the cavity 1 and is locked, the parts are at the center position of the upper electrode plate 4 and the lower electrode plate 3, thereby facilitating the activation of the surface of the parts.
