Description

Technical Field

[0001] This utility model relates to the field of automatic unloading technology for PCB drilling machines, and in particular to an automatic lifting, clamping and transferring device. Background Technology

[0002] Drilling is a crucial step in PCB manufacturing. Currently, mainstream PCB drilling machines generally employ a dual-pin fixing mode for precise positioning of the PCB: a positioning pin (front pin and rear pin) is drilled into each of the front and rear edges of the PCB, and corresponding front and rear clamping devices on the worktable clamp these two pins respectively, thus ensuring the PCB is firmly fixed during processing. After drilling, the drilled PCB needs to be removed from the worktable and transferred to the subsequent processing area or board placement area. However, existing technology heavily relies on manual operation for this unloading step. Operators must manually release the front and rear clamping pins from the pins, then remove the PCB from the clamps and move it away. This manual unloading method is not only inefficient and increases labor costs, but also carries the risk of damage to the board surface or deformation of the positioning pins due to operational errors, affecting production yield and equipment uptime.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1, referring to Figures 1-2 This is the first embodiment of the present invention. This embodiment provides an automatic lifting, clamping, and transferring device. The automatic lifting, clamping, and transferring device includes a lifting cylinder 1, which is disposed on both sides of the front clamping pin, with one end connected to an air pump; a clamping assembly 2, which includes a moving plate 21, a clamping member 22, and a driving member 23. The moving plate 21 is disposed above the worktable, and the clamping member 22 is disposed above the moving plate 21 for driving the moving plate 21 to move; a transferring assembly 3, which is disposed on the rear side of the worktable, includes a conveyor belt 31 and a guide member 32. The conveyor belts 31 are arranged in pairs, and the guide member 32 is disposed in the middle of the pair of conveyor belts 31.

[0028] The lifting cylinder 1 provides vertical lifting force, causing the front of the PCB board to tilt up, thus physically separating the front pin from the front clamping pin. The moving plate 21 carries the clamping component and transmits the rearward moving force. The clamping component 22 directly clamps the front edge of the PCB board. The driving component 23 drives the moving plate to move horizontally backward. The conveyor belt 31 stably transports the PCB board to the board placement area. The guide component 32 guides the rear pin to disengage from the rear clamping pin and transition to the conveyor belt. It is worth noting that the support legs of the conveyor belt can be raised and lowered (this is existing technology and will not be described in detail here). When the drilling machine is working, the transfer component 3 is located above the worktable and will not affect the movement of the worktable.

[0029] When in use, the front and rear clamping pins are opened, the transfer assembly 3 is lowered, the worktable is moved back until the position of the rear clamping pin coincides with the position of the guide 32, the lifting cylinder 1 lifts the front part of the PCB board so that the front pin is disengaged from the front clamping pin, the clamping member 22 clamps the front edge of the board, the driving member 23 drives the moving plate 21 to move back, the rear pin slides and is guided in the rear clamping pin, then the rear pin slides into the guide groove, the gripper is released, and the conveyor belt moves the PCB board to the board placement area.

[0030] Example 2, refer to Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] Specifically, the outer side of the lifting cylinder 1 is provided with threads that engage with the threaded hole on the worktable; it is worth noting that the outer side of the lifting cylinder 1 is provided with a nut, which locks the position of the lifting cylinder 1 after it is screwed into the threaded hole.

[0032] Specifically, the movable plate 21 is provided with a sliding guide rail 211, one end of which is located below the cable tray, and the other end is connected to the movable plate 21.

[0033] The sliding guide rail 211 constrains the moving plate 21 to move only horizontally backward to prevent tilting. In this embodiment, the sliding guide rail 211 has three sections and can extend to the edge of the worktable.

[0034] Specifically, the clamping component 22 includes a cylinder 221, a connecting block 222, a driving block 223, a fixed seat 224, and a gripper 225. The connecting block 222 is connected to the piston of the cylinder 221, the connecting block 222 is connected to the driving block 223, the fixed seat 224 is disposed on one side of the cylinder 221, and the gripper 225 is connected to the fixed seat 224.

[0035] Cylinder 221 provides the power for opening and closing of gripper 225; connecting block 222 connects to piston: transmitting linear thrust; drive block 223 pushes gripper to rotate; fixed seat 224 supports gripper and limits the axis of motion; gripper 225 directly contacts PCB board to achieve non-destructive clamping; preferably, the moving plate 21 below gripper 225 also has an opening to facilitate the rotation and clamping of gripper 225.

[0036] Specifically, the fixed base 224 is provided with a through hole 2241, and the drive block 223 slides in conjunction with the through hole 2241; the through hole 2241 restricts the drive block 223 to only move in a straight line, so as to avoid the displacement of the thrust causing the gripper 225 to malfunction.

[0037] Specifically, one end of the fixed base 224 is provided with an opening 2242, which is connected to the through hole 2241; the gripper 225 is provided with a rotating shaft 2251, which rotates and engages with both sides of the opening 2242.

[0038] Specifically, a first toothed block 2252 is provided at one end of the rotating shaft 2251 near the drive block 223; a second toothed block 2231 is provided on the side of the drive block 223 near the opening 2242, and the first toothed block 2252 meshes with the second toothed block 2231.

[0039] The cylinder drives the drive block 223 to make linear motion. The first tooth block 2252 meshes with the second tooth block 2231, causing the gripper 225 to rotate and hold. It is worth noting that the end of the gripper 225 is hook-shaped, which can effectively hold the PCB board.

[0040] Specifically, the driving component 23 includes a lead screw 231, a drive motor 232, a first slider 233, and a connecting plate 234. The connecting plate 234 is disposed on both sides of the moving plate 21. The lead screw 231 is arranged parallel to the movement direction of the moving plate 21. The output end of the drive motor 232 is connected to the lead screw 231. The first slider 233 is disposed on the connecting plate 234 and is threadedly engaged with the lead screw 231.

[0041] The lead screw 231 converts the motor rotation into linear displacement, and the drive motor 232 provides precise and controllable power. The first slider 233 is threadedly engaged with the lead screw 231 to drive the connecting plate 234 to move, thereby transmitting the backward movement force to the clamping assembly 2.

[0042] Specifically, the drive component 23 is also provided with a linear guide 235 and a second slider 236. The linear guide 235 is arranged parallel to the lead screw 231, and the second slider 236 is arranged on the connecting plate 234 and slides with the linear guide 235.

[0043] The linear guide 235 shares the load of the moving plate 21, and the second slider 236 prevents the moving plate 21 from tilting, thus improving the stability of the transfer.

[0044] Specifically, the guide component 32 includes a first guide block 321 and a second guide block 322. The first guide block 321 is disposed on the rear side of the rear clamping pin on the worktable, and the second guide block 322 matches the first guide block 321. Both the first guide block 321 and the second guide block 322 are provided with a sliding groove 323.

[0045] The first guide block 321 receives the rear pin, and the second guide block 322 matches the first guide block 321: extending the guide path; the slide 323 guides the rear pin to slide smoothly into the conveyor belt to avoid jamming. When the gripper 225 moves the PCB board to the position where the front pin is above the first guide block 322, the PCB board is released. At this time, the front pin falls into the slide 323 of the first guide block 322, and the PCB board is transported to the board placement area by the conveyor belt 31.

[0046] In use, the lifting cylinder 1 automatically lifts the front of the PCB after drilling, so that the front pin can be reliably disengaged from the front clamping pin. The clamping assembly 2 uses the driving component 23 to drive the moving plate 21 and the gripper 225 to accurately clamp the front edge of the board and move smoothly backward along the sliding guide rail 211. At this time, the rear pin slides in the rear clamping pin to form a natural guide. The guide component 32 of the transfer assembly seamlessly receives the rear pin and guides the board to disengage from the rear clamping pin through the matching first guide block 321 and second guide block 322 and their sliding groove 323. Finally, the conveyor belt automatically transfers the board to the board placement area.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
