Description

Technical Field

[0001] This utility model belongs to the field of PCB processing technology, and in particular relates to a board gripping robot and a PCB board processing equipment. Background Technology

[0002] In the field of printed circuit board (PCB) manufacturing, the intelligentization and automated transfer functions of processing tools have become an important trend for future development. This helps simplify equipment operation processes, shorten tool changeover times, and effectively reduce downtime. Currently, due to the frequent need to change PCBs to be processed, operators generally rely on manually placing the boards on the worktable. This method of manually transferring PCBs one by one to the worktable is not only time-consuming but also particularly inconvenient when placing and aligning large PCBs.

[0003] Although some mechanisms for clamping and transferring sheets have emerged, these mechanisms suffer from drawbacks such as complex structure and large size. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a gripping robot with a simple and practical structure and a small assembly volume, facilitating direct assembly into processing equipment without complex modifications. This utility model also discloses a PCB board processing device incorporating the aforementioned gripping robot.

[0005] The specific technical solution of this utility model is as follows: A gripper includes a base plate, a rotating pressure plate, and a drive mechanism; one side of the base plate is configured as a positioning surface, and the other side is configured as a mounting surface; the drive mechanism is disposed on the mounting surface, and the drive mechanism is drively connected to the rotating pressure plate to clamp the plate between the mounting surface and the free end of the rotating pressure plate.

[0006] This application uses the base plate on which the drive mechanism is placed as a positioning element, making it part of the clamping and holding plate. Therefore, the application requirements can be met by using a single rotating pressure plate. Compared with the prior art which requires the setting of relatively moving grippers, it greatly reduces the assembly space and volume occupied, thus achieving miniaturization. Furthermore, due to its simple structure, it does not require complex modifications to the processing equipment.

[0007] Preferably, the substrate is provided with a hole, the active end of the driving mechanism is located on one side of the positioning surface, and one end of the rotating pressure plate is connected to the active end of the driving mechanism so as to move in the hole; The other end of the rotating pressure plate passes through the hole to press the plate firmly against the positioning surface.

[0008] This structure can further reduce its volume by utilizing the provided holes.

[0009] Preferably, the drive mechanism is configured as a rack and pinion mechanism.

[0010] This structure has a simple transmission mechanism and high transmission efficiency.

[0011] Preferably, the driving mechanism includes a cylinder, a rack, a gear, and a drive shaft; the cylinder is mounted on the mounting surface, the driving end of the cylinder is connected to the rack, the gear is rotatably connected to the mounting surface via the drive shaft, and the gear and rack mesh; the rotating pressure plate is connected to the drive shaft.

[0012] This structure can effectively drive the rotating pressure plate, and it is simple in structure and easy to assemble.

[0013] Preferably, a connecting plate for changing the direction of cylinder power output is provided between the cylinder and the rack.

[0014] This structure utilizes the specific structure of the connecting plate, which can effectively save space and achieve miniaturization.

[0015] Preferably, a guide member is provided between the connecting plate and the mounting surface.

[0016] The guide member can improve the motion stability of the rack, ensure the rotational stability of the meshing gear, and thus improve the driving efficiency of the rotating pressure plate.

[0017] Preferably, the connecting plate and the rack are detachably connected, one of the connecting plate and the rack is provided with an assembly groove, and the other is provided with an assembly protrusion, and the assembly groove and the assembly protrusion are slidably engaged.

[0018] This structure is simple and easy to install, which can effectively maintain the rack and reduce the reduction in process efficiency caused by a lot of assembly and disassembly.

[0019] Preferably, it further includes a support base, which is placed on the mounting surface and is rotatably connected to one end of the drive shaft; The support base is provided with a limiting part, and the rack moves inside the limiting part.

[0020] The limiting part can provide the rack with the ability to move, and prevent the rack from moving crookedly, which would result in the inability to drive the gear to rotate well.

[0021] Preferably, it also includes a second support base, which is placed on the mounting surface and is rotatably connected to the other end of the drive shaft.

[0022] This structure can improve the output stability of the drive shaft and ensure the smooth rotation of the drive shaft.

[0023] A PCB board processing device includes a board gripping robot as described above.

[0024] Compared with existing technologies, this utility model has a simple structure and small size, which can effectively clamp and hold the board, thus improving the overall production efficiency of the board processing technology. This utility model avoids manual operation, effectively reduces labor costs, avoids excessive board placement time caused by human factors, and effectively improves work efficiency.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] This embodiment discloses a PCB board processing equipment, including a board-grabbing robot. The board-grabbing robot is used to pre-place the PCB board to be processed onto the router's worktable for positioning and fixation. The router then executes a router program, completing the forming process of the PCB board along a preset trajectory. After processing, the board-grabbing robot restarts, removing the processed PCB board and transferring it to a material bin for subsequent processes. This equipment achieves automatic board grabbing and automatic positioning, effectively solving the problem of difficult manual positioning and significantly improving work efficiency.

[0029] Specifically, such as Figures 1-3 As shown, a gripper includes a base plate 1, a rotating pressure plate 2, and a drive mechanism; one side of the base plate 1 is configured as a positioning surface 3, and the other side is configured as a mounting surface 4; the drive mechanism is disposed on the mounting surface 4, and the drive mechanism and the rotating pressure plate 2 are connected in a transmission manner to clamp the plate 100 between the mounting surface 4 and the free end of the rotating pressure plate 2.

[0030] Before clamping the plate 100, there is a space between the rotating pressure plate 2 and the substrate 1 for placing the plate 100. When the plate 100 is located in this space, the driving mechanism is activated, and the rotating pressure plate 2 rotates relative to the substrate 1. This causes one side of the plate 100 to be pressed by the rotating pressure plate 2, so that the other side of the plate 100 is tightly pressed against the positioning surface 3 of the substrate 1. Since there is a certain contact area between the rotating pressure plate 2 and the plate 100, the rotating pressure plate 2 and the substrate 1 can clamp and hold the plate 100, thereby meeting the requirements for transporting the plate 100. It is known that if two relatively moving grippers are set, in addition to requiring a more complex transmission structure, it is also necessary to meet the requirement of synchronous movement of the two grippers. Therefore, the robot structure of this embodiment is not only simple, but also effectively reduces the plate slippage caused by incomplete clamping.

[0031] In this embodiment, the substrate 1 is provided with a hole 5. The active end of the driving mechanism is located on one side of the positioning surface 3. One end of the rotating pressure plate 2 is connected to the active end of the driving mechanism to move within the hole 5. The other end of the rotating pressure plate 2 passes through the hole 5 to press the plate 100 against the positioning surface 3. Since the rotating pressure plate 2 can move within the hole 5, a large rotation radius relative to the substrate 1 can be avoided. By reducing the rotation radius through the hole 5, miniaturization can be achieved accordingly.

[0032] In this embodiment, the driving mechanism is configured as a rack and pinion mechanism. Specifically, the driving mechanism includes a cylinder 6, a rack 7, a gear 8, and a drive shaft 9. The cylinder 6 is mounted on the mounting surface 4, and the driving end of the cylinder 6 is connected to the rack 7. The gear 8 is rotatably connected to the mounting surface 4 via the drive shaft 9, and the gear 8 and rack 7 mesh. The rotating pressure plate 2 is connected to the drive shaft 9. The extension or shortening of the driving end of the cylinder 6 causes the rack 7 to move along its axis, thereby enabling the gear 8 to rotate forward or backward. At this time, the drive shaft 9 rotates due to the rotation of the gear 8, thus driving the rotating pressure plate 2 to rotate synchronously. This structure has high transmission efficiency.

[0033] To further reduce size, a connecting plate 10 is provided between the cylinder 6 and the rack 7 to change the power output direction of the cylinder 6. In this embodiment, the connecting plate 10 has a 90° structure, which can transmit the power output direction of the cylinder 6 to one side of the cylinder 6, so that the rack 7 and the cylinder 6 are in parallel positions, thereby shortening the assembly space. The connecting plate 10 can be a split structure or a one-piece structure.

[0034] To better drive the rack 7, a guide member is provided between the connecting plate 10 and the mounting surface 4. The guide member includes a guide rail 11 and a guide block 12, which are slidably engaged. The guide rail 11 is disposed on the connecting plate 10, and the guide block 12 is disposed on the mounting surface 4. Alternatively, the guide rail 11 can be disposed on the mounting surface 4, and the guide block 12 can be disposed on the connecting plate 10. Thus, the movement direction of the connecting plate 10 is always along the extension direction of the guide rail 11.

[0035] In this embodiment, the connecting plate 10 and the rack 7 are detachably connected. One of the connecting plate 10 and the rack 7 is provided with an assembly groove 13, and the other is provided with an assembly protrusion 14. The assembly groove 13 and the assembly protrusion 14 are slidably engaged. In this embodiment, the end of the connecting plate 10 is provided with an assembly groove 13, and the end of the rack 7 is provided with an assembly protrusion 14. The assembly protrusion 14 configures the end of the rack 7 into an I-beam structure, thereby satisfying the engagement requirements with the connecting plate 10. Furthermore, the connecting plate 10 is provided with a first pin hole, and the rack 7 is provided with a second pin hole. After the connecting plate 10 and the rack 7 are properly engaged, a pin is inserted into the first and second pin holes to complete the connection. Since the mating groove and the mating protrusion can abut against each other, a single pin is sufficient for stable assembly.

[0036] In this embodiment, a first support base 15 is also included. The first support base 15 is placed on the mounting surface 4 and is rotatably connected to one end of the transmission shaft 9. The first support base 15 is provided with a limiting part 16, and the rack 7 moves inside the limiting part 16. The limiting part 16 is a cover-shaped structure, which limits the rack 7 in its vertical position and prevents the rack 7 from tilting relative to the far end of the guide rail 11 component. Furthermore, a second support base 17 is also included. The second support base 17 is placed on the mounting surface 4 and is rotatably connected to the other end of the transmission shaft 9. The first support base 15 and the second support base 17 provide positioning support for the transmission shaft 9, thereby effectively improving the motion stability of the transmission shaft 9, the gear 8, and the rotating pressure plate 2.

[0037] Therefore, under the action of compressed air, the cylinder 6 moves to drive the connecting plate 10 to drive the rack 7 to move together. The connecting plate 10 connects to the rack 7 and drives the gear 8 to rotate. In turn, the gear 8 drives the rotating pressure plate 2 to rotate. When the end face of the printed PCB board (board 100) extends into the lower part of the substrate 1, the rotating pressure plate 2 rotates to press the printed PCB board, thereby realizing the function of gripping the board. After the board is successfully gripped, it can be accurately placed on the workbench for positioning and placement.

[0038] Therefore, this embodiment realizes the function of mechanized gripping and positioning of the board 100, eliminating the need for manual multiple picking and placing of the board 100. This not only saves labor costs and reduces the excessively long board placement time caused by human factors, but also improves the intelligence and work efficiency of the equipment.

[0039] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
