A plurality of vertical plates 642 are arranged on the base plate 641 corresponding to the lower side of the plug plate 632, and an inclined pushing surface is arranged on the upper end of the vertical plate 642, and the pushing roller 635 abuts against the pushing surface. There is at least one position point on the push surface, so that when the push roller 635 is located at this position point, the locking roller 634 on the upper end of the plug plate 632 does not protrude from the upper end surface of the upper bracket 31; and there is another position point, so that when the push roller 635 is located at this position point, the locking roller 634 on the upper end of the plug plate 632 can be clamped in the locking groove 612 to complete the carrier locking. Preferably, the second two ends of the second sub-slide rail 643 are configured with second limit members 645 for controlling the sliding stop position of the base plate 641 to ensure that the push roller 635 can pass through the above two position points during the sliding process of the base plate 641 to achieve the locking and unlocking of the carrier.

[0050] like Figure 7As shown, the lower conveyor line 4 is placed below the machine 1 and is used to transport a single reflow carrier. The lower conveyor line 4 includes a lower bracket 41 fixed below the machine 1, and the lower bracket 41 is provided with a second slide rail 42 and a second pusher 43 for driving the carrier 2 to slide along the second direction on the second slide rail 42.

The driven wheels 433 are respectively arranged at both ends of the lower bracket 41 along the transmission direction, and the rotating motor 431 drives the driving wheel 432 to rotate, thereby driving the belt 434 to rotate. A second push plate 435 is fixedly connected to the belt 434, and a second push portion 4351 is protrudingly provided on one side of the second push plate 435 close to the second slide rail 42. The second push portion 4351 can be mutually engaged with the buckle portion 23 on the side of the carrier, and the second push plate 435 and the belt 434 rotate synchronously while driving the carrier 2 to slide. Preferably, a third sub-slide rail 436 parallel to the second slide rail 42 is provided below the second push plate 435, and the second push plate 435 is slidably provided on the third sub-slide rail 436 through a slider, which effectively enhances the stability of the second push plate 435 during the sliding process.

[0052] like Figure 1 As shown, two groups of transfer components 5 are correspondingly arranged, which are respectively placed at the two ends of the upper conveyor line 3 and the lower conveyor line 4. One group is used to connect the output end of the upper conveyor line 3 and the input end of the lower conveyor line 4, and the other group is used to connect the output end of the lower conveyor line 4 and the input end of the upper conveyor line 3. After the processed products are taken away from the output end of the upper conveyor line 3, the empty carrier is transferred to the lower conveyor line 45 through the transfer component 5 and then flows back to the input end of the upper conveyor line 3 through another group of transfer components, thereby realizing the recycling of the carrier 2.

[0053] like Figure 7 As shown, the transfer assembly 5 includes a side bracket 51 fixed to the machine platform 1 , and a liftable transfer support plate 53 and a third lift member 54 for driving the transfer support plate 53 to move up and down are disposed on the side bracket 51 .

[0054] like Figure 8As shown, a subordinate slide rail 55 is provided on the transfer support plate 53, and the subordinate slide rail 55 is extended along the first direction. The subordinate slide rail 55 can be connected with the first slide rail 32 and the second slide rail 42 respectively by lifting and lowering the transfer support plate 53, so as to ensure that the carrier 2 can slide from the second slide rail 42 to the subordinate slide rail 55 or slide from the subordinate slide rail 55 to the first slide rail 32. Preferably, a side baffle 56 is provided on the side of the transfer support plate 53 away from the first slide rail 32 or the second slide rail 42, so as to control the sliding stop position of the carrier and prevent the carrier 2 from falling off from the subordinate slide rail 55.

The third lifting cylinder 542 extends to drive the lifting connecting plate 541 to rise, and the rotating wheel 543 drives the lifting belt 544 to rise, thereby driving the transfer supporting plate 53 to rise, and vice versa.

[0057] like Figure 8 , 9 As shown, preferably, a guide column 545 that cooperates with the lifting connecting plate 541 is disposed in the lifting guide groove to improve the stability of the lifting connecting plate 541 during the lifting process.

[0058] Working principle:

[0059] The first pushing cylinder 331 drives the second pushing plate 332 to push in the first direction, and the first pushing portion 3321 is engaged with the buckle portion 23 to drive the carrier 2 to slide in the first direction.

[0060] Once the carrier 2 reaches the processing station, the positioning ball 611 on one side of the locking plate 61 engages with the locking groove 612, and the carrier 2 stops sliding. The second push cylinder 644 below the carrier 2 pushes the base plate 641, and the vertical plate 642 slides synchronously. The push roller 635 below the plug plate 632 rolls from the lowest point on the upper end surface of the vertical plate 642 to the highest point. The locking roller 634 on the top of the plug plate 632 rises and is inserted into the locking groove 612 of the locking plate 61 to fix the position of the carrier and perform the processing operation. After the processing is completed, the second push cylinder 644 drives the base plate 641 to retreat, the plug plate 632 drops, the carrier is in a loose state, and the first push cylinder 331 continues to move, driving the carrier to slide to the next station.

[0061] This reciprocating process continues until the carrier moves to the last station, and the external robot takes away the product. The first pusher 33 pushes the empty carrier onto the transfer support plate 53, and the third lifting member 54 is actuated to drive the transfer support plate 53 down to the height of the lower conveyor line 3. The rotary motor 431 is actuated to drive the belt 434 to rotate, and the second push plate 435 on the belt 434 pushes the carrier to slide in the second direction until the carrier passes through the second slide rail 42 and slides onto another transfer assembly, and then is driven to the height of the upper conveyor line 3 by another transfer assembly, and the product is loaded again for the processing cycle.

[0062] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
