The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] It is understandable that, referring to Figures 1 to 6 The utility model provides a PCB board 300 gong board machine board loading auxiliary device, including a support frame 200 and a plurality of positioning plates 100, the upper end of the positioning plate 100 is vertically provided with a plurality of first positioning pins 110, the plurality of first positioning pins 110 are arranged at intervals, the first positioning pins 110 can be inserted into the limiting holes 310 of the PCB board 300, and the positioning plate 100 is provided with a plurality of positioning holes 120; the top of the support frame 200 is provided with a top plate 210, the upper end surface of the top plate 210 is vertically provided with a plurality of second positioning pins 211, the plurality of second positioning pins 211 are arranged at intervals, the second positioning pins 211 correspond one to one with the positioning holes 120, and the second positioning pins 211 can be inserted into the positioning holes 120 to locate the position of the positioning plate 100, the support frame 200 is provided with a plurality of support plates 220, the support plates 220 are used to carry the positioning plate 100, and the plurality of support plates 220 are evenly spaced along the vertical direction.

[0031] When stacking the boards, first place a positioning plate 100 on the upper end of the top plate 210, and insert the second positioning pin 211 into the positioning hole 120 to locate the position of the positioning plate 100, which can reduce the possibility of position deviation of the positioning plate 100 when placing the boards. Then, multiple PCB boards 300 are placed on the upper end of the positioning plate 100 in sequence, and the first positioning pin 110 is inserted into the limiting hole 310 of the PCB board 300 to locate the position of the PCB board 300, so that the multiple PCB boards 300 can be aligned and stacked to improve the processing accuracy of the gong board. After the PCB boards 300 are stacked, the positioning plate 100 is lifted to transfer the multiple PCB boards 300 as a whole to one of the support plates 220. The operation is cyclically repeated to stack multiple groups of PCB boards 300 in sequence. When placing the boards, it is only necessary to place the positioning plate 100 and the multi-layer PCB boards 300 as a whole on the working platform of the gong board machine, so that stacking and gong boarding can be performed separately and simultaneously without stopping the machine for stacking, thereby improving the gong boarding efficiency of the PCB boards 300.

[0032] In addition, since the top plate 210 is located on the top of the support frame 200 , an operating space can be reserved above the top plate 210 for placing the PCB board 300 , thereby facilitating the stacking of the PCB board 300 .

[0033] Furthermore, the stacked PCB boards 300 are respectively carried by a plurality of support plates 220, which facilitates centralized storage and transportation.

[0034] It should be noted that in order to reduce the position offset of the PCB board 300 and improve the processing accuracy, a plurality of limit pins are usually set on the working platform of the roulette machine. When the positioning plate 100 and the multi-layer PCB board 300 are placed as a whole on the working platform of the roulette machine, the limit pins can be inserted into the positioning holes 120 of the positioning plate 100 to locate the position of the positioning plate 100, thereby locating the position of the PCB board 300.

[0035] The number of the first positioning pins 110 and the number of the second positioning pins 211 can be three or four and arranged in a triangle or quadrilateral to improve the stability of positioning.

[0036] Universal rollers 250 may be provided at the four corners of the bottom of the support frame 200 , respectively, so that the support frame 200 can be conveniently moved to a corresponding work station by the universal rollers 250 to facilitate the loading of the PCB board 300 .

[0037] It is understandable that, referring to Figure 1 、 Figure 2 and Figure 5The ends of the first positioning pin 110 and the second positioning pin 211 are both hemispherical. Since the end of the first positioning pin 110 is hemispherical, when the first positioning pin 110 is aligned with and inserted into the limiting hole 310 of the PCB board 300, the wear of the first positioning pin 110 on the PCB board 300 can be reduced. Furthermore, since the end of the second positioning pin 211 is hemispherical, when the second positioning pin 211 is aligned with and inserted into the positioning hole 120 of the positioning plate 100, the wear of the second positioning pin 211 on the positioning plate 100 can be reduced, thereby extending the service life of the positioning plate 100.

[0038] It is understandable that, referring to Figure 1 and Figure 3 A first groove 212 is formed at the upper end of the top plate 210. The first groove 212 extends from the edge of the top plate 210 toward the center. Since the first groove 212 extends from the edge of the top plate 210 toward the center, a worker's hand can be inserted into the bottom of the positioning plate 100 along the first groove 212 to facilitate lifting the positioning plate 100.

[0039] Specifically, refer to Figure 3 A plurality of first grooves 212 are provided, and the plurality of first grooves 212 are evenly spaced along the circumference of the top plate 210. Since the plurality of first grooves 212 are evenly spaced along the circumference of the top plate 210, it is convenient for a worker to reach into the bottom of the positioning plate 100 from the first grooves 212 at different positions along the circumference of the top plate 210 to apply force to lift the positioning plate 100.

[0040] It is understandable that, referring to Figures 1 to 3 A positioning block 213 is rotatably connected to the upper end of the top plate 210. The positioning block 213 can abut the upper edge of the positioning plate 100 to limit the vertical movement of the positioning plate 100. When the positioning plate 100 is placed on the top plate 210, the positioning block 213 is rotated so that it abuts the upper edge of the positioning plate 100 to limit the vertical movement of the positioning plate 100. This can improve the positional stability of the positioning plate 100 and facilitate the stacking of PCBs.

[0041] Specifically, refer to Figures 1 to 3 Two positioning blocks 213 are provided, one on each side of the top plate 210. The positioning blocks 213 on opposite sides simultaneously abut against the edges of the positioning plate 100, thereby balancing the forces on the opposite sides of the positioning plate 100 and further improving the positional stability of the positioning plate 100, thereby facilitating the stacking of PCBs.

[0042] Specifically, refer to Figure 1 、 Figure 3 and Figure 7A blind hole 214 is provided at the center of the upper end of the top plate 210, and a lifting block 230 is slidably connected to the top plate 210. The lifting block 230 is located in the blind hole 214. The lifting block 230 is provided with a supporting portion 231 and a guide portion 232. A compression spring 240 is sheathed on the guide portion 232. The two ends of the compression spring 240 are respectively connected to the bottom wall of the blind hole 214 and the supporting portion 231. The compression spring 240 can drive the supporting portion 231 to rise. When the positioning plate 100 is placed on the top plate 210, the positioning plate 100 first abuts against the support part 231, and the positioning plate 100 is pressed down to drive the support part 231 to move down, and the compression spring 240 is compressed and deformed until the support part 231 is flush with the upper end surface of the top plate 210, and then the positioning block 213 is rotated to make the positioning block 213 abut against the upper end edge of the positioning plate 100 to limit the vertical movement of the positioning plate 100. When the PCB board 300 is stacked, the positioning block 213 is rotated to make the positioning block 213 disengage from the positioning plate 100. At the same time, the compression spring 240 elastically recovers and drives the support part 231 to rise. The support part 231 lifts the positioning plate 100, so that the positioning plate 100 is separated from the upper end surface of the top plate 210, which can facilitate workers to reach into the bottom of the positioning plate 100 and lift the positioning plate 100.

[0043] Specifically, refer to Figure 7 A vertical guide rod 215 is protruding from the bottom wall of the blind hole 214, and the guide portion 232 is slidably mounted on the guide rod 215. Since the guide portion 232 is slidably mounted on the guide rod 215, the guide portion 232 is guided vertically by the guide rod 215, which can improve the lifting stability of the lifting block 230, thereby improving the lifting stability of the positioning plate 100.

[0044] It is understandable that, referring to Figure 1 and Figure 4 A second groove 221 is formed at the upper end of the support plate 220, extending from the edge toward the center of the support plate 220. Since the second groove 221 extends from the edge toward the center of the support plate 220, a worker's hand can be inserted into the bottom of the positioning plate 100 along the second groove 221 to facilitate lifting the positioning plate 100.

[0045] Specifically, refer to Figure 1 and Figure 4 A rear baffle 222 is vertically provided on one side of the support plate 220 away from the second groove 221. The rear baffle 222 can abut against one side of the positioning plate 100. By abutting against the side of the positioning plate 100, the positioning plate 100 can be limited, thereby improving the position stability of the positioning plate 100 and reducing the possibility of the positioning plate 100 and the PCB board 300 falling.

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
