[0052] For the tray feeding mechanism 40, the box feeding mechanism 50 and the cover feeding mechanism 70, the three are loading operations. The corresponding trays, boxes and cover plates are placed on the corresponding feeding bottom plate 42. The feeding linear lifting module 41 moves upward with the materials through the feeding bottom plate 42. After the material arrival position sensor 43 senses that the materials are in place, the feeding linear lifting module 41 stops moving. After the top material is taken away, the feeding linear lifting module 41 drives the feeding bottom plate 42 to move upward again. The material arrival position sensor 43 stops moving after sensing the materials again. This cycle is repeated until all the materials are taken away. At this time, loading is required again.

[0057] Manual loading can be used for loading trays, cover plates, and loading and unloading of material boxes. The operator can directly place the corresponding materials on the corresponding feeding bottom plate 42. However, this will take some time to wait for the loading to be completed before working again, resulting in a waste of time. In this solution, a trolley is also designed to achieve fast loading and unloading operations; Figure 1 As shown, a feeding trolley 100 is provided at the material tray feeding mechanism 40 , the material box feeding mechanism 50 and the cover plate feeding mechanism 70 , and a material receiving trolley 110 is provided at the material box receiving mechanism 60 .

At this time, the bottom plate 102 of the material cart is located directly above the feeding bottom plate 42, and the feeding bottom plate 42 moves upward through the first gap 1022 to lift the materials upward, and the materials are separated from the bottom plate 102 of the material cart. At this time, the feeding cart 100 can be pulled out from the corresponding feeding mechanism to prepare for the next loading operation.

[0060] During the material unloading operation, when the material arrival position sensor 43 senses that there is a material box on the feeding bottom plate 42, the material receiving trolley 110 can be pushed into the material box receiving mechanism 60. At this time, the feeding bottom plate 42 is located directly above the material trolley bottom plate 102, and the feeding bottom plate 42 moves downward. When the feeding bottom plate 42 passes through the material trolley bottom plate 102, the material box is left on the material trolley bottom plate 102; when the feeding bottom plate 42 moves to the second position sensor 45 and sends a signal, it means that material unloading is possible, and the material receiving trolley 110 can be pulled out from the material box receiving mechanism 60.

A rotating clamping block 1011 is provided on the cylinder 1010; after the feeding trolley 100 or the receiving trolley 110 is pushed in, the rotating clamping cylinder 1010 rotates to drive the rotating clamping block 1011 to rotate, and the rotating clamping block 1011 rotates to the movement path of the feeding trolley 100 or the receiving trolley 110 and clamps with the trolley clamping block 109 to prevent the feeding trolley 100 or the receiving trolley 110 from leaving, thereby achieving positioning in the X-axis direction; and when the feeding trolley 100 or the receiving trolley 110 needs to be pulled out, the rotating clamping cylinder 1010 rotates to separate the rotating clamping block 1011 from the trolley clamping block 109, and the feeding trolley 100 or the receiving trolley 110 is manually pulled out; in order to facilitate pushing in or pulling out, a trolley handle 1012 is further provided on the trolley steel frame 101.

[0062] In summary, the circuit board is taken from the feeding mechanism 20 through the flipping mechanism 30, and then flipped and lifted and taken by the conveying component 80, thereby receiving the circuit board from the previous process and transitioning through the flipping mechanism 30, and the conveying component 80 realizes the placement of the circuit board and the transportation of the material tray; the material tray feeding mechanism 40, the material box feeding mechanism 50 and the cover plate feeding mechanism 70 realize the continuous supply of corresponding materials; the material box cover plate conveying mechanism 90 realizes the transportation of the material box and the cover plate; and the material box receiving mechanism 60 realizes the function of continuously collecting materials from the full material box; at the same time, the feeding cart 100 and the receiving cart 110 are designed to reduce the time for loading and unloading materials and improve the overall work efficiency of the system; the machine is used to work fully automatically, the efficiency of plate placement is improved, manual participation is no longer required, human resources are saved, and at the same time, the circuit board will not be damaged due to contact, bumps, static electricity and other factors.
