[0028] AGVs are vehicles that automatically travel along predetermined routes, replacing manual material handling and enabling automated material transport to improve transfer efficiency. They are particularly useful for transporting PCBs. To facilitate centralized transfer, PCB carriers are required. AGVs transfer PCBs by placing and retrieving these carriers. However, if the PCB carriers are misaligned, the AGVs struggle to locate and identify the carriers, preventing them from properly retrieving materials and impacting PCB transfer.

[0029] It is understandable that, referring to Figures 1 to 4 The utility model provides a PCB board carrier for use with an AGV, including a base 100 and an L-shaped support plate 200. The bottom surface of the base 100 is provided with two first positioning holes 110 and two second positioning holes 120. The two first positioning holes 110 are symmetrically arranged along the width direction of the base 100, and the two second positioning holes 120 are symmetrically arranged along the width direction of the base 100. The positioning portion of the placement platform can be inserted into the first positioning holes 110 to locate the position of the base 100, and the positioning portion of the AGV can be inserted into the second positioning holes 120 to locate the position of the base 100; the L-shaped support plate 200 is fixedly arranged above the base 100.

[0030] When unloading, the AGV places the PCB board carrier loaded with PCB boards on the placement platform of the equipment such as the PCB feeder, PCB collector and storage rack by lowering the lifting platform. Since there are two first positioning holes 110 on the bottom surface of the base 100, the two first positioning holes 110 are symmetrically arranged along the width direction of the base 100. The positioning part of the placement platform is inserted into the first positioning holes 110 to locate the position of the base 100, thereby locating the position of the L-shaped support plate 200. This can reduce the possibility of positional deviation of the PCB board carrier during placement, making it easier for the AGV to identify and find the PCB. B board carrier, when taking materials, since there are two second positioning holes 120 on the bottom surface of the base 100, the two second positioning holes 120 are symmetrically arranged along the width direction of the base 100, and the AGV moves to the position of the positioning part of the lifting platform and aligns it with the second positioning holes 120, so that the lifting platform lifts the PCB board carrier, and at the same time, the positioning part of the lifting platform is inserted into the second positioning hole 120 to locate the position of the base 100, thereby locating the position of the L-shaped support plate 200, which can reduce the possibility of the PCB board carrier being offset and falling during transportation, thereby improving the transportation efficiency and quality of the PCB board.

[0031] In addition, the position of the PCB board carrier is positioned by cooperating with the positioning part of the lifting platform through the second positioning hole 120 to reduce the possibility of position deviation of the PCB board carrier, and the positioning part of the placement platform can be easily aligned and inserted into the first positioning hole 110 to locate the placement position of the PCB board carrier.

[0032] It should be noted that equipment such as the board thrower, board collector and storage rack are all provided with a placement platform for placing the PCB board carrier. The placement platform is provided with a positioning portion corresponding to the first positioning hole 110. The positioning portion of the placement platform can be inserted into the first positioning hole 110 to locate the position of the PCB board carrier. The lifting platform of the AGV is provided with a positioning portion corresponding to the second positioning hole 120. The positioning portion of the AGV can be inserted into the second positioning hole 120 to locate the position of the PCB board carrier.

[0033] It is understandable that, referring to Figure 2 The bottom surface of the base 100 is provided with an identification mark 130. By providing the identification mark 130 on the bottom surface of the base 100, the AGV can read the information of the identification mark 130 when retrieving materials, which facilitates the scheduling of the AGV to transfer the PCB board carrier. The relevant information is connected with the scheduling system to realize the AGV automatic transfer of the PCB board carrier. Moreover, when the AGV recognizes the identification mark 130, it can control the AGV to stop moving, so that the positioning part of the lifting platform can be aligned with the second positioning hole 120, which facilitates the positioning part of the lifting platform to be aligned with the second positioning hole 120 and inserted into the second positioning hole 120.

[0034] It should be noted that the identification mark 130 may be a QR code or a barcode, etc., as long as the AGV can read the information of the identification mark 130 .

[0035] Specifically, refer to Figure 1 and Figure 2 The identification mark 130, the first positioning hole 110, and the second positioning hole 120 are all located on the same straight line. By arranging the identification mark 130, the first positioning hole 110, and the second positioning hole 120 on the same straight line, the AGV can read the identification mark 130 and align with the second positioning hole 120 at the same time, thereby improving the convenience of detection and positioning.

[0036] Specifically, refer to Figure 2 The bottom surface of the base 100 is provided with a groove 140, and the identification mark 130 is disposed on the bottom wall of the groove 140. By disposing the identification mark 130 on the bottom wall of the groove 140, the identification mark 130 can be separated from the placement surface, thereby reducing the possibility of the identification mark 130 being worn and extending the service life of the identification mark 130.

[0037] It is understandable that, referring to Figure 1 、 Figure 2 and Figure 5 A positioning sleeve 150 is provided in each of the first positioning hole 110 and the second positioning hole 120 . The positioning portion can be inserted into the positioning sleeve 150 . An annular flange 151 is protruded from the outer periphery of one end of the positioning sleeve 150 , and the annular flange 151 can abut against the base 100 . By inserting the end of the positioning sleeve 150 away from the annular flange 151 into the first positioning hole 110 or the second positioning hole 120 until the annular flange 151 abuts the base 100 to limit the axial movement of the positioning sleeve 150, it is convenient to locate the installation position of the positioning sleeve 150, and then the positioning sleeve 150 is fixedly installed in the first positioning hole 110 or the second positioning hole 120 by welding or threaded connection, so that the positioning part of the AGV or the positioning part of the placement platform can be inserted into the positioning sleeve 150, and the positioning part of the placement platform and the wall surface of the first positioning hole 110 or the positioning part of the AGV and the wall surface of the second positioning hole 120 are separated by the positioning sleeve 150 to reduce the wear on the wall surfaces of the first positioning hole 110 and the second positioning hole 120. After the positioning sleeve 150 is worn, only the positioning sleeve 150 needs to be replaced, and there is no need to replace the PCB board carrier as a whole to maintain the positioning accuracy, which can reduce the cost of use.

[0038] Specifically, refer to Figure 5A guide portion 152 is provided at one end of the positioning sleeve 150 away from the annular flange 151. The inner diameter of the guide portion 152 gradually decreases along the axial direction of the positioning sleeve 150 toward the annular flange 151. Because the inner diameter of the guide portion 152 gradually decreases along the axial direction of the positioning sleeve 150 toward the annular flange 151, the positioning portion can gradually slide into the inner hole of the positioning sleeve 150 along the inner wall of the guide portion 152, guiding the positioning portion to align with and insert into the inner hole of the positioning sleeve 150, thereby improving positioning accuracy.

[0039] It is understandable that, referring to Figure 1 and Figure 4 The L-shaped support plate 200 includes a bottom plate 210 and a back plate 220. The bottom plate 210 and the back plate 220 are perpendicular to each other. The bottom plate 210 is provided with a clearance groove 211. The clearance groove 211 extends along the length of the bottom plate 210 from the side of the bottom plate 210 away from the back plate 220 to the connection between the bottom plate 210 and the back plate 220. Because the clearance groove 211 extends along the length of the bottom plate 210 from the side of the bottom plate 210 away from the back plate 220 to the connection between the bottom plate 210 and the back plate 220, a transporter can reach into the bottom of the PCB through the clearance groove 211, making it easier for the transporter to lift the PCB from the bottom.

[0040] Specifically, refer to Figure 1 and Figure 4 A plurality of escape grooves 211 are provided, and the plurality of escape grooves 211 are spaced apart along the width direction of the bottom plate 210. The plurality of escape grooves 211 are spaced apart along the width direction of the bottom plate 210, so that multiple transporters can simultaneously reach into the bottom of the PCB board through different escape grooves 211, thereby improving transport efficiency.

[0041] Specifically, refer to Figure 1 and Figure 3 A vertical reinforcing rib 300 is provided between the back plate 220 and the base 100, with both ends of the reinforcing rib 300 fixedly connected to the back plate 220 and the base 100, respectively. The vertical reinforcing rib 300 provided between the back plate 220 and the base 100 improves the overall structural strength of the PCB carrier, thereby reducing the possibility of the L-shaped support plate 200 turning over or detaching from the base 100.

[0042] Specifically, refer to Figures 1 to 3 A vertical reinforcement plate 400 is provided between the bottom plate 210 and the base 100. The two ends of the reinforcement plate 400 are fixedly connected to the bottom plate 210 and the base 100, respectively. The vertical reinforcement plate 400 provided between the bottom plate 210 and the base 100 improves the overall structural strength of the PCB carrier, thereby reducing the possibility of the L-shaped support plate 200 turning over or detaching from the base 100.

[0043] It should be noted that a plurality of anti-slip strips may be provided on the side of the back plate 220 close to the bottom plate 210. The anti-slip strips are provided along the length of the back plate 220 and are evenly spaced along the width of the back plate 220. The anti-slip strips can increase the frictional resistance between the PCB and the back plate 220, thereby improving the positional stability of the PCB.

[0044] 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.
