Description

Technical Field

[0001] The utility model relates to the technical field of PCB production devices, and particularly relates to a sheet material positioning carrier and a sheet material loading device. Background Art

[0002] PCB boards are widely used in various electronic related products. During the production process of PCB boards, it is necessary to load the PCB boards, or when stacking PCB boards, it is necessary to load sheet materials (such as aluminum sheets, cardboard, etc.) that can separate two PCB boards. Currently, the loading carriers used in the production process of PCB boards usually set guide rods on the carrier plate for carrying the sheet materials. The guide rods can position the sheet materials. During loading, the transfer mechanism descends and sucks up the sheet materials through a suction cup. As the loading process progresses, the sheet materials on the carrier plate will gradually decrease, that is, the thickness of the sheet materials placed on the carrier plate will gradually decrease. The descending height of the transfer mechanism needs to be gradually increased in order to suck up the sheet materials. However, the guide rods for positioning the sheet materials will hinder the descent of the transfer mechanism, resulting in a limited descending height of the transfer mechanism, making it difficult to suck up the sheet materials through the suction cup of the transfer mechanism, causing a picking obstacle. The transfer mechanism may also interfere and collide with the guide rods during the descending process, damaging the equipment. Summary of the Utility Model

Sliding blocks can also be provided on the first movable fork 301 and the second movable fork 302, and slots are opened on the bearing plate 1 and the bottom plate 2. The sliding blocks are stuck in the slots and slide in the slots.

[0060] In the technical solution of this embodiment, by setting up a bracket 13, when in use, the bottom plate 2 of the sheet material positioning carrier is placed on the AGV trolley, and the sheet materials are stacked on the carrying plate 1. After the sheet materials are stacked, the sheet material positioning carrier is transferred to the bracket 13 by the AGV trolley, so that the part of the carrying plate 1 protruding from the bottom plate 2 is placed on the bracket 13, and the material loading can be started. As the sheet materials are consumed, the thickness of the sheet materials gradually decreases, and the lifting drive component 14 can be started. The lifting drive component 14 drives the bracket 13 to move along the Z direction. As the bracket 13 moves along the Z direction, the carrying plate 1 placed on the bracket 13 also moves with the bracket 13, so that the height of the upper end of the sheet materials gradually increases. Since the bottom plate 2 is placed on the upper end of the AGV trolley, the bottom plate 2 is affected by gravity and it is always close to the AGV trolley, so The height of the guide rod 4 will not change. When the height of the sheet is flush with the upper end of the guide rod 4, stop the lifting drive component 14 and continue loading to adjust the height of the sheet stacked on the supporting plate 1. When the sheet is used up, the AGV trolley can be directly used to move the entire sheet positioning carrier away to replenish the sheet. After the sheet is replenished, the AGV trolley is used to move the sheet positioning carrier to the sheet loading device, and the sheet positioning carrier is placed on the bracket 13 again to continue loading. It is more convenient to use. Since the sheet positioning carrier itself does not have a power mechanism, hydraulic system, etc., it does not need to use power wires. Therefore, it will not be affected by the power wires during transportation, and transportation is also more convenient. In this embodiment, the Z direction is along the height direction of the guide rod 4.

[0061] See also Figure 10 and Figure 11 In a preferred embodiment of the present invention, the lifting drive component 14 includes a driving motor 1401, a driving sprocket 1402, a driven sprocket 1403, a chain 1404 and a screw 1405. The driving sprocket 1402 is arranged at the output end of the driving motor 1401, the driving sprocket 1402 and the driven sprocket 1403 are connected by the chain 1404, the driven sprocket 1403 is arranged on the screw 1405, and the nut of the screw 1405 is fixedly connected to the bracket 13.

[0062] In the technical solution of this embodiment, when in use, the drive motor 1401 is started, and the drive motor 1401 forms a sprocket chain transmission mechanism through the drive sprocket 1402, the driven sprocket 1403, and the chain 1404, driving the lead screw 1405 to rotate, and then the nut of the lead screw 1405 moves along the lead screw 1405, driving the bracket 13 to move. A linear electric guide rail can also be used to replace the drive motor 1401, the drive sprocket 1402, the driven sprocket 1403, the chain 1404 and the lead screw 1405. Compared with the lifting drive component 14 composed of the above components, the linear electric guide rail runs more smoothly and can be selected according to specific needs.

[0063] It should be noted that the sheet loading device further includes a frame. The driving motor 1401 and the lead screw 1405 can be fixedly connected to the frame of the sheet loading device respectively to ensure driving stability. In addition, a plurality of limiting rods can be arranged on both sides in the height direction of the lead screw 1405. The limiting rods are fixedly connected to the frame of the sheet loading device. A sliding sleeve is arranged on the limiting rod, and the sliding sleeve slides on the sliding rod. The sliding sleeve is fixedly connected to the bracket 13. Since the sheet positioning carrier and the sheet placed above are relatively heavy, the limiting rods and the sliding sleeve can be added to improve the stability of the movement of the bracket 13.

[0064] Please refer to Figure 10 , in a preferred embodiment of the present invention, the cross-section of the bracket 13 is in a U shape.

[0065] In the technical solution of this embodiment, the bracket 13 is set in a U shape. When placing the sheet positioning carrier, the part of the bearing plate 1 protruding from the bottom plate 2 can be directly placed on the bracket 13, which is relatively convenient to place.

[0066] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
