Description

A PCB board transfer device Technical Field

[0001] This utility model relates to the field of transfer device technology, specifically a PCB board workstation transfer device. Background Technology

[0002] A PCB, also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is made using electronic printing technology, it is called a "printed" circuit board. PCBs have evolved from single-layer to double-sided, multi-layer, and flexible, and continue to develop in their own ways.

[0003] Existing patent document CN221795270U provides a PCB board transfer device. Addressing the problems of existing transfer devices being bulky and inconvenient for placement, and the tendency for PCBs to collide and be squeezed together during transfer, leading to wear and a reduced PCB yield, the present invention proposes the following solution: It includes two symmetrically arranged U-shaped rods, two horizontal rods fixedly connected to the inner walls of the corresponding U-shaped rods, two vertical rods fixedly positioned between the top of their corresponding horizontal rods and the top wall of the U-shaped rods, and four first connecting rods symmetrically fixedly connected to one side of one of the U-shaped rods. In this invention, the rectangular plate and the carrier plate are designed for foldable storage, greatly reducing the device's volume and facilitating transportation and placement. A first limiting groove and a second limiting groove are provided to separate each PCB board, preventing squeezing or collisions that could cause wear.

[0004] However, while existing PCB board transfer devices can transfer PCB boards, the process requires placing a carrying frame or rack on the device before placing the PCB board on it. Upon arrival at the designated workstation, the PCB board is placed there. However, the transfer device is difficult to adjust in height, and workers are required to bend over for extended periods, leading to high workload and reduced efficiency. Therefore, we propose a new PCB board transfer device. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, this utility model provides a PCB board station transfer device to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a PCB board workstation transfer device, comprising a transfer cart, a lifting frame fixedly connected to the top of the transfer cart, a pushing frame fixedly connected to one side of the lifting frame, a handle fixedly connected to the inner side of the pushing frame, a limiting groove formed on the inner side of the lifting frame, a lifting plate movably connected to the inner side of the lifting frame through the limiting groove, limiting blocks fixedly connected to both the front and back of the lifting plate, a top plate fixedly connected to the top of the lifting frame, a lifting motor mounted on the top of the top plate, a lifting screw fixedly connected to the drive end of the lifting motor, and a nut seat threadedly connected to the outer side of the lifting screw.

[0009] Preferably, a mounting slot is provided on one side of the transfer vehicle, and a battery panel is installed on the inner side of the mounting slot.

[0010] Preferably, a control panel is fixedly connected to the front of the push frame, and control buttons are installed on the front of the control panel.

[0011] Preferably, there are two limiting blocks, which are symmetrically arranged and are movably connected to the limiting groove.

[0012] Preferably, the lifting plate is made of metal material and is fixedly connected to the nut seat.

[0013] Preferably, the bottom of the transfer vehicle is fixedly connected with four casters, which are located at the four corners of the bottom of the transfer vehicle.

[0014] (III) Beneficial Effects

[0015] This utility model provides a PCB board transfer device at the workstation, which has the following advantages:

[0016] (1) This PCB board workstation transfer device, through the setting of a lifting frame, lifting plate, lifting motor, lifting screw and nut seat, when using the PCB board workstation transfer device, the worker places the rack or frame on the lifting plate, and then starts the lifting motor by controlling the button according to the placement requirements. The lifting motor drives the lifting screw to rotate, and the nut seat drives the lifting plate to rise and fall through the limit groove on the lifting frame due to the rotation direction of the lifting screw, thereby adjusting the height of the rack and frame on the lifting plate. Then the worker can place the PCB board in the rack and frame. When the bottom layer is placed, the height of the lifting plate can be lowered in turn so that the rack and frame are at a suitable height. When the transfer is carried to the designated position for material retrieval, the worker uses the same method to make the rack and frame at a suitable height and take out the PCB board in turn. This eliminates the need for the worker to bend over when using the transfer device to pick up and put down the PCB board, thus reducing the worker's workload and improving work efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4. This utility model provides a technical solution: a PCB board workstation transfer device, including a transfer cart 1. A lifting frame 3 is fixedly connected to the top of the transfer cart 1. A push frame 4 is fixedly connected to one side of the lifting frame 3. A handle 5 is fixedly connected to the inner side of the push frame 4. A limit groove 8 is opened on the inner side of the lifting frame 3. A lifting plate 9 is movably connected to the inner side of the lifting frame 3 through the limit groove 8. Limit blocks 10 are fixedly connected to both the front and back of the lifting plate 9. A top plate 11 is fixedly connected to the top of the lifting frame 3. A lifting motor 12 is installed on the top of the top plate 11. A lifting screw 13 is fixedly connected to the drive end of the lifting motor 12. A nut seat 14 is threadedly connected to the outer side of the lifting screw 13.

[0024] Furthermore, a mounting slot 15 is provided on one side of the transfer vehicle 1, and a battery panel 16 is installed inside the mounting slot 15. The battery panel 16 can provide power to power the lifting components for lifting and lowering.

[0025] Furthermore, a control panel 6 is fixedly connected to the front of the pusher frame 4. Control buttons 7 are installed on the front of the control panel 6, which facilitates operation by staff and allows the transfer device to move up and down as needed.

[0026] Furthermore, there are two limit blocks 10, which are symmetrically arranged. The limit blocks 10 are movably connected to the limit groove 8. Through the limit blocks 10, the lifting plate 9 can only move up and down in a straight line.

[0027] Furthermore, the lifting plate 9 is made of metal and is fixedly connected to the nut seat 14. The lifting plate 9, made of metal, is more robust, durable, and less prone to damage.

[0028] Furthermore, the bottom of the transfer vehicle 1 is fixedly connected with four casters 2. The four casters 2 are located at the four corners of the bottom of the transfer vehicle 1. The casters 2 facilitate the movement of the transfer device, allowing the transfer device to move to the designated position as needed.

[0029] Working Principle: After installation, first check the installation, fixation, and safety protection of this utility model. When using the PCB board transfer device, the worker places the rack or frame on the lifting plate 9. Then, according to the placement requirements, the lifting motor 12 is started via control button 7. The lifting motor 12 drives the lifting screw 13 to rotate. The nut seat 14, due to the rotation direction of the lifting screw 13, causes the lifting plate 9 to rise and fall through the limiting groove 8 on the lifting frame 3, thereby adjusting the height of the rack and frame on the lifting plate 9. The worker can then place the PCB board inside the rack and frame. When the bottom layer is placed, the height of the lifting plate 9 can be lowered sequentially to ensure that the rack and frame are at a suitable height. After placement, when transferring the equipment, the operator lowers the lifting plate 9 to its lowest position, then grasps the handle 5 and applies a pushing force. The pushing force is transmitted to the push frame 4 through the handle 5, while the casters 2 rotate to move the transfer device. When the equipment is transferred to the designated location for material retrieval, the operator uses the same method to ensure that the rack and frame are at a suitable height and then removes the PCB board sequentially. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
