[0013] In one embodiment, two first mounting plates are spaced apart to support the two ends of the first mounting block, and a first support beam is provided between the two first mounting plates, with the first mounting block disposed on the first support beam; and / or

[0014] The second mounting plate is provided in two spaced intervals to support the two ends of the second mounting block respectively, and a second support beam is provided between the two second mounting plates, with the second mounting block disposed on the second support beam.

[0015] In one embodiment, the carrier further includes a clamping assembly disposed on the first mounting plate and / or the second mounting plate for clamping the PCB board within the positioning slot.

[0041] PCB boards are an indispensable basic component in electronic devices, used to support and connect electronic components. Electrical connections and mechanical fixation between electronic components are achieved by printing conductive lines and pads on an insulating substrate. In the PCB board production process, PCB board transportation is an essential link. Some carriers use slot structures to support PCB boards. However, because the slot structure is open, the PCB board is prone to slipping when the carrier is moved.

[0042] This utility model proposes a carrier for supporting PCB boards.

[0043] Please see Figure 1 In one embodiment of this utility model, the carrier 20 includes:

[0044] The support frame 100 includes a horizontally arranged first plate 110 and a second plate 120 disposed on the first plate 110, wherein the first plate 110 and the second plate 120 form an angle.

[0045] Mounting bracket 200 includes a first mounting plate 210 and a second mounting plate 220 vertically connected. The first mounting plate 210 is disposed on a first plate 110, and the second mounting plate 220 is disposed on a second plate 120. The distance between the end of the first mounting plate 210 away from the second plate 120 and the first plate 110 is greater than the distance between the end of the first mounting plate 210 closer to the second plate 120 and the first plate 110. Similarly, the distance between the end of the second mounting plate 220 closer to the first plate 110 and the second plate 120 is greater than the distance between the end of the second mounting plate 220 away from the first plate 110 and the second plate 120.

[0046] The positioning slot is located on the mounting bracket 200 and is used to support the PCB board.

[0047] In the technical solution of this utility model, the carrier 20 includes a support frame 100 and a mounting frame 200. The support frame 100 includes a first plate 110 and a second plate 120. One end of the first plate 110 is connected to one end of the second plate 120 at a certain angle. The first plate 110 is horizontally arranged. Within the angle range, the mounting frame 200 is provided. The mounting frame 200 includes a first mounting plate 210 and a second mounting plate 220. The first mounting plate 210 and the second mounting plate 220 are vertically connected, making the mounting frame 200 have an L-shaped structure. A positioning groove is provided on the mounting frame 200 for positioning the bottom edge and side edge of the PCB board. The first mounting plate 210 is inclined relative to the first plate 110. The distance between the end of the second mounting plate 220 away from the first mounting plate 110 and the end of the second mounting plate 220 away from the first mounting plate 110 is greater than the distance between the end of the second mounting plate 220 away from the first mounting plate 110 and the second mounting plate 120 is greater than the distance between the end of the second mounting plate 220 away from the first mounting plate 110. That is, the mounting bracket 200 is in an inclined state. When the PCB board is placed in the positioning slot, the bottom plate of the PCB board is in an inclined state, and the end away from the second mounting plate 120 is higher than the end of the second mounting plate 120. This makes the PCB board more stable in the positioning slot. Compared with the horizontally set mounting bracket 200, the inclined storage of the PCB board makes the PCB board more stable during transportation. It can prevent the PCB board from slipping on the open side during transportation, thus improving the stability and safety of transportation.

[0048] Please refer to Figure 1 and Figure 4Specifically, the carrier 20 is used for a board receiving and unloading device. The board receiving and unloading device includes a housing 10, which houses a robotic arm and a transport mechanism. At least one set of processing stations is also provided within the housing 10. The carrier 20 can be moved to the processing station by an AGV (Automated Guided Vehicle) cart, where the robotic arm can transfer PCB boards transported by the transport mechanism onto the carrier 20, or vice versa. The carrier 20 includes a support frame 100, which includes a first plate 110 and a second plate 120. The first plate 110 and the second plate 120 form a certain angle, which is greater than or equal to 90°. In this embodiment, the angle is 90°. The material of the support frame 100 is not limited; it can be made of wood or, to ensure long-term stability, a high-strength metal material can be used. A mounting bracket 200 is provided within the included angle formed by the support frame 100. The mounting bracket 200 is inclined, meaning that the end of the first mounting plate 210 on the first plate 110 that is farther away from the second plate 120 is higher than the end that is closer to the second plate 120. The inclined mounting bracket 200 causes the PCB board to also be in an inclined state. The side and bottom edges of the PCB board contact the second mounting plate 220 and the first mounting plate 210, respectively, which can prevent the PCB board from slipping to one side when stored horizontally. In addition, a positioning groove is provided on the mounting bracket 200 for positioning the PCB board. The positioning groove can be set according to the size of the PCB board to ensure that the PCB board is more stable on the carrier 20 and avoid displacement or shaking. In one embodiment, an anti-slip pad or other structure can be provided in the positioning groove to further improve the fixing effect of the PCB board. The structure of the carrier 20 can reduce manual operation, reduce labor costs, and improve production efficiency.

[0049] In one embodiment, the angle between the first mounting plate 210 and the first plate 110 is greater than or equal to 30°. The tilt angle can ensure that the mounting bracket 200 provides sufficient support for the PCB board, while also avoiding the problem of the PCB board slipping due to insufficient support caused by an angle that is too small. In addition, the tilt angle can better distribute the weight of the PCB board and reduce local pressure.

[0050] In the embodiments of this utility model, the angle between the first mounting plate 210 and the first plate 110 is less than or equal to 65°, which can avoid the problem of the PCB board slipping off the top side due to excessive tilt angle, and improve the stability of the carrier 20 in supporting the PCB board. The tilt angle is between 30° and 65°, which can not only support the PCB board more stably, but also adapt to PCB boards of different shapes and sizes, thus improving the stability and compatibility of the carrier 20.

[0051] In an embodiment of the present invention, the carrier 20 further includes a plurality of first support blocks 300, which are disposed between the first mounting plate 210 and the first plate 110, and the height of the plurality of first support blocks 300 increases from the end of the first plate 110 that is closer to the second plate 120 to the end that is farther away from the second plate 120.

[0052] Please refer to Figure 1 and Figure 2 A first support block 300 is provided between the first mounting plate 210 and the first plate 110. Multiple first support blocks 300 are provided at intervals from the end of the first mounting plate 210 near the second plate 120 to the end away from the second plate 120. The height of the first support block 300 increases from the end near the second plate 120 to the end away from the second plate 120. This makes the end of the first mounting plate 210 away from the second plate 120 higher than the end near the second plate 120. The increasing height of the first support block 300 can provide progressive support for the first mounting plate 210 and ensure its stability at different positions.

[0053] In one embodiment, a single first support block 300 is provided, which extends from one end of the second plate 120 toward the end away from the second plate 120 and increases in height. This can also provide progressive support for the first mounting plate 210. Compared with the previous embodiment, providing multiple first support blocks 300, i.e., the discontinuous arrangement of the first support blocks 300, can not only provide progressive support but also reduce the overall weight of the vehicle 20.

[0054] The vehicle 20 also includes a plurality of second support blocks 310, which are disposed between the second mounting plate 220 and the second plate 120, and the height of the plurality of second support blocks 310 decreases from the end of the second plate 120 that is closer to the first plate 110 to the end that is farther away from the first plate 110.

[0055] Please refer to Figure 1 and Figure 2 Similar to the first support block 300, a second support block 310 is provided between the second mounting plate 220 and the second plate 120. Multiple second support blocks 310 are spaced apart in the direction from the end of the second mounting plate 220 near the first plate 110 to the end away from the first plate 110. The height of the second support blocks 310 decreases from the end near the first plate 110 to the end away from the first plate 110. This makes the distance between the end of the second mounting plate 220 away from the first plate 110 and the second plate 120 smaller than the end near the first plate 110. That is, the distance between the second mounting plate 220 and the second plate 120 decreases from bottom to top. The decreasing height of the second support blocks 310 can provide progressive support for the second mounting plate 220, ensuring its stability in different positions.

[0056] In one embodiment, a single second support block 310 is provided, which extends from one end of the first plate 110 toward the end away from the first plate 110 and decreases in height. This can also provide progressive support for the second mounting plate 220. Compared with the previous embodiment, providing multiple second support blocks 310, i.e., the discontinuous arrangement of the second support blocks 310, can not only provide progressive support but also reduce the overall weight of the vehicle 20.

[0057] In an embodiment of this utility model, the carrier 20 further includes a first mounting block 400 and a second mounting block 410. The first mounting block 400 is mounted on a first mounting plate 210, and the second mounting block 410 is mounted on a second mounting plate 220. The positioning groove includes a plurality of first slots 401 provided on the first mounting block 400 and a plurality of second slots 411 provided on the second mounting block 410. The first slots 401 and the second slots 411 are correspondingly provided, and the first slots 401 and the second slots 411 are used to support the adjacent sides of the PCB board.

[0058] Please refer to Figure 1 A first mounting block 400 is provided on the first mounting plate 210, extending horizontally. A second mounting block 410 is provided on the second mounting plate 220, also extending horizontally. A first slot 401 is provided on the first mounting block 400, and multiple first slots 401 are spaced apart along the length of the first mounting block 400. Similarly, multiple second slots 411 are spaced apart along the length of the second mounting block 410. Each first slot 401 corresponds to a second slot 411 to support the bottom plate and side plate of the same PCB board. By supporting the bottom plate and side plate of the PCB board, the PCB board can be made more stable on the carrier 20, preventing it from falling off during the movement of the carrier 20. The multiple first slots 401 and second slots 411 can support multiple PCB boards, improving transfer efficiency. Furthermore, each PCB board does not contact each other, avoiding scratches.

[0059] In one embodiment, the depth of the positioning groove is 10-40mm. This depth range allows the PCB board to be stored stably, prevents the PCB board from shaking and deforming on the carrier 20, and avoids excessive depth, which would make the carrier 20 too thick and increase its weight.

[0060] In an embodiment of this utility model, two first mounting plates 210 are spaced apart to support the two ends of the first mounting block 400 respectively, and a first support beam 230 is provided between the two first mounting plates 210. The first mounting block 400 is mounted on the first support beam 230. Please refer to [reference needed]. Figure 1The two first mounting plates 210 are arranged opposite each other and connected in the middle by the first support beam 230 and screws, which makes the installation of the first mounting block 400 more stable, and thus makes the storage of the PCB board more stable.

[0061] Two second mounting plates 220 are spaced apart to support the two ends of the second mounting block 410 respectively. A second support beam 240 is provided between the two second mounting plates 220, and the second mounting block 410 is mounted on the second support beam 240. Similarly, the two second mounting plates 220 are arranged opposite each other and installed at the two ends of the second mounting block 410. The two second mounting plates 220 are fixedly connected to each other by the second support beam 240 and screws, making the installation of the second mounting block 410 more stable, and thus making the storage of the PCB board more stable.

[0062] Please refer to Figure 1 In this embodiment of the invention, the carrier 20 further includes a clamping component 500, which is disposed on the first mounting plate 210 and / or the second mounting plate 220 for clamping the PCB board in the positioning slot. The clamping component 500 can prevent the PCB board from shaking and causing deformation, and can also keep the PCB board in a vertical and consistent reference position, avoiding deviations in the board removal position in subsequent processes. In addition, the clamping component 500 can also be used for PCB boards of different thicknesses, so that PCB boards of different thicknesses can be stored stably. The clamping component 500 can be disposed on the first mounting plate 210 corresponding to the first slot 401, or on the second mounting plate 220 corresponding to the second slot 411, or one clamping component 500 can be disposed on both the first mounting plate 210 and the second mounting plate 220. No limitation is made here.

[0063] In one embodiment, the clamping assembly 500 includes:

[0064] Support base 510 is disposed on first mounting plate 210 and / or second mounting plate 220;

[0065] Multiple grippers 520 are provided, and the multiple grippers 520 are spaced apart along the length direction of the support base 510, and each gripper 520 corresponds to a positioning groove.

[0066] Please refer to Figure 1 and Figure 3The clamping assembly 500 includes a horizontally arranged support base 510. If the clamping assembly 500 is set on the first mounting plate 210, the two ends of the support base 510 are respectively mounted on the two first mounting plates 210 and parallel to the first support beam 230. If the clamping assembly 500 is set on the second mounting plate 220, the two ends of the support base 510 are respectively mounted on the two second mounting plates 220 and parallel to the second support beam 240. Multiple grippers 520 are arranged at intervals along the length of the support base 510. The grippers 520 can be two-finger grippers 520, vacuum suction cup grippers 520, pneumatic grippers 520, or electric grippers 520, etc., without limitation. Each gripper 520 corresponds to a positioning slot, so that each PCB board in the positioning slot has a corresponding gripper 520 for clamping, thereby improving the stability of PCB board transfer and storage.

[0067] In one embodiment, the support base 510 includes:

[0068] Two first mounting parts 511 are provided, and the two first mounting parts 511 are respectively mounted on the two second mounting plates 220. A mounting hole is provided at the end of the first mounting part 511 away from the second mounting plate 220.

[0069] The second mounting part 512 is located at the end of the first mounting part 511 away from the second mounting plate 220, and both ends of the second mounting part 512 are respectively connected to the two first mounting parts 511. Each end of the second mounting part 512 is provided with an elongated hole 5121, and the long axis of the elongated hole 5121 extends along the length direction of the second mounting part 512.

[0070] Fasteners are screwed through the elongated hole 5121 and into the mounting hole.

[0071] Please refer to Figure 3 The clamping assembly 500 is disposed on the second mounting plate 220. The support base 510 includes a first mounting part 511 and a second mounting part 512. The two first mounting parts 511 are disposed opposite each other and are respectively mounted on the two second mounting plates 220 by screws. The second mounting part 512 is disposed between the two first mounting parts 511. The gripper 520 is disposed on the second mounting part 512. The second mounting part 512 is parallel to the second support beam 240. An elongated hole 5121 is provided at each end of the second mounting part 512. A mounting hole is provided at the end of the first mounting part 511 near the second mounting part 512. A fastener passes through the elongated hole 5121 and is screwed into the mounting hole to realize the connection between the first mounting part 511 and the second mounting part 512. The setting of the elongated hole 5121 allows the installation position of the second mounting part 512 to be finely adjusted, so that the gripper 520 on the second mounting part 512 can better correspond to the PCB board on the positioning groove, which is convenient for more stable clamping.

[0072] In another embodiment, the clamping assembly 500 is disposed on the first mounting plate 210, and the two first mounting parts 511 are respectively mounted on the two first mounting plates 210 by screws. The two ends of the second mounting part 512 are respectively connected to a second mounting part 512 and are parallel to the first support beam 230.
