Description

Technical Field

[0001] This utility model relates to the field of PCB board loading and unloading devices, specifically to a PCB board testing loading and unloading transport device. Background Technology

[0002] A PCB, or printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection.

[0003] PCBs require electrical testing. During unloading after testing and loading before testing, PCBs are typically stacked for easy transport. Current technology usually places the stacked PCBs on a carrier board, which is then transferred using a transport device. However, this technology has the following problems: the transport device lacks restraints for the carrier board. When the transport device transfers the stacked PCBs, the carrier board can easily move relative to the transport device, causing the PCBs to shake during transport and potentially leading to damage. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a PCB board testing loading and unloading conveying device, comprising:

[0005] A movable first frame, on which multiple positioning slots are provided;

[0006] A telescopic cylinder has a carrier frame at its output end, a movable cylinder on the carrier frame, a push plate at its output end, a second frame on the push plate, a carrier plate for placing a PCB board on the second frame, and a positioning frame corresponding to a positioning slot on the second frame. The telescopic cylinder is used to drive the positioning frame to insert into the positioning slot, and the movable cylinder is used to drive the push plate to move.

[0007] The second frame is equipped with a limiting component, which is used to limit the PCB board.

[0008] Furthermore, the push plate is provided with a slot corresponding to the positioning frame, and the moving cylinder is used to drive the slot to insert into the positioning frame.

[0009] Furthermore, the limiting component includes a two-finger gripper and a first limiting block. The output end of the two-finger gripper is provided with a plurality of second limiting blocks. The two-finger gripper is connected to the first limiting block. The two-finger gripper is used to drive the second limiting blocks to move to cooperate with the first limiting block, thereby limiting the PCB board.

[0010] Furthermore, the first limiting block is provided with a stepped groove, and the second limiting block is provided with a stepped structure corresponding to the stepped groove.

[0011] Furthermore, the positioning frame has a triangular structure.

[0012] Furthermore, the first frame is provided with a positioning post, and the second frame is provided with a positioning hole. When the positioning frame is inserted into the positioning groove, the positioning post is inserted into the positioning hole.

[0013] Furthermore, the first frame is equipped with multiple casters.

[0014] Furthermore, the first frame is equipped with handles.

[0015] The beneficial effects of this utility model are: by setting the positioning frame and positioning groove, the carrier board is relatively limited to the first frame during transportation. When the first frame moves to transfer the stacked PCB board, the carrier board is not easy to move relative to the first frame, thereby making the PCB board less likely to shake and be damaged during transportation, thus improving the stability of the PCB board during transportation.

Detailed Implementation

[0021] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Please refer to Figure 1 This utility model provides a PCB board testing loading and unloading transport device 100, including a movable first frame 10 and a telescopic cylinder 20. The first frame 10 is provided with multiple positioning slots 11. The output end of the telescopic cylinder 20 is provided with a carrier frame 21, the carrier frame 21 is provided with a moving cylinder 22, the output end of the moving cylinder 22 is provided with a push plate 23, a second frame 24 is placed on the push plate 23, the second frame 24 is provided with a carrier plate 242 for placing PCB boards, and the second frame 24 is provided with positioning frames 241 corresponding to the positioning slots 11. The telescopic cylinder 20 is used to drive the positioning frames 241 to insert into the positioning slots 11, and the moving cylinder 22 is used to drive the push plate 23 to move.

[0023] Specifically, in this embodiment, the positioning frame 241 has a triangular structure. The first frame 10 is equipped with a handle 14 and multiple casters 13. When transferring the stacked PCB boards, the telescopic cylinder 20 drives the positioning frame 241 to insert into the positioning slot 11. After the second frame 24 is placed on the first frame 10, the moving cylinder 22 drives the push plate 23 to move off the second frame 24. Then, the casters 13 move the first frame 10.

[0024] After testing, the stacked PCB boards are placed on the second frame 24. The telescopic cylinder 20 drives the carrier frame 21 to rise and fall, causing the push plate 23 to move the second frame 24, thereby allowing the positioning frame 241 to insert into the positioning slot 11. The positioning frame 241 and the positioning slot 11 ensure that the carrier board 242 is relatively positioned relative to the first frame 10 during transportation. When the first frame 10 moves to transfer the stacked PCB boards, the carrier board 242 is less likely to move relative to the first frame 10, thus preventing the PCB boards from shaking and being damaged during transportation, and improving the stability of the PCB boards during transport.

[0025] Please refer to Figure 2 and Figure 3The first frame 10 is equipped with positioning posts 12, and the second frame 24 is equipped with positioning holes 2411. When the positioning frame 241 is inserted into the positioning slot 11, the positioning posts 12 are inserted into the positioning holes 2411. Through the cooperation of the positioning posts 12 and the positioning holes 2411, the first frame 10 and the second frame 24 are relatively fixed, which further limits the relative positioning of the carrier board 242 and the first frame 10 during transportation. This makes it less likely for the PCB board to shake during transportation and cause damage, thus further improving the stability of the PCB board during transportation.

[0026] Please refer to Figure 1 and Figure 2 The push plate 23 is provided with a slot 231 corresponding to the positioning frame 241. The moving cylinder 22 is used to drive the slot 231 to insert into the positioning frame 241. By setting the slot 231, when the telescopic cylinder 20 drives the push plate 23 to move, and thus drives the second frame 24 to rise and fall, the push plate 23 and the second frame 24 are relatively fixed, so that the carrier plate 242 is less likely to shake during the rise and fall, thus improving the stability of PCB board transfer.

[0027] Please refer to Figure 1 and Figure 2 The second frame 24 is equipped with a limiting component 30, which is used to limit the PCB board. The limiting component 30 includes a two-finger gripper 31 and a first limiting block 32. The output end of the two-finger gripper 31 is provided with a plurality of second limiting blocks 33. The two-finger gripper 31 is connected to the first limiting block 32. The two-finger gripper 31 is used to drive the second limiting blocks 33 to move and cooperate with the first limiting block 32, thereby limiting the PCB board.

[0028] Please refer to Figure 2 The first limiting block 32 is provided with a stepped groove 321, and the second limiting block 33 is provided with a stepped structure corresponding to the stepped groove 321. Specifically, there are two of each of the first limiting blocks 32 and the second limiting blocks 33. The two first limiting blocks 32 are arranged in pairs about the central axis in the length direction of the PCB board, and the two second limiting blocks 33 are arranged in pairs about the central axis in the width direction of the PCB board.

[0029] By cooperating with the second limiting block 33 and the stepped groove 321, which have a stepped structure, the second limiting block 33 and the stepped groove 321 can adapt to PCBs of different heights and lengths through the stepped structure when encountering PCBs of different specifications. Then, the two-finger gripper 31 drives the two second limiting blocks 33 to slide relative to each other, so that the two second limiting blocks 33 can be adjusted according to the width of different PCB models. This allows the edges of the PCB and the edges of the two second limiting blocks 33 to fit together, achieving the purpose of limiting the PCB while adapting to PCBs of various specifications, thus improving practicality.
