[0002] With the development of society and the acceleration of urbanization, signboards, as important guidance tools and information transmission media, play an increasingly important role in our daily lives. Whether it is a public building, a commercial place or a tourist attraction, clear and accurate signboards are needed to guide people. The production of signboards involves multiple links, including design, printing, cutting, bending and drilling. Among them, the drilling process is crucial to the final installation of the signboard, which is directly related to the stability and aesthetics of the signboard.

[0003] At present, most of the signboard drilling processes on the market still rely on manually operated traditional drilling machines or manual drilling tools. Manual drilling has low safety and it is difficult to ensure the consistency of hole positions for the same type of signboards. Traditional drilling machines require manual clamping each time to ensure positioning before drilling, which reduces production efficiency. Summary of the invention

[0015] Beneficial effects of the present invention:

[0016] 1. Clamping arms are fixed on both sides of the workbench. The clamping arms are slidably connected to the frame.

[0033] By adopting the above technical solution, clamping arms 300 are fixedly provided on both sides of the workbench 200, and the clamping arms 300 are slidably connected to the frame 100. The displacement of the workbench 200 relative to the drilling assembly is realized by the driving of the driving mechanism. When the workbench 200 moves up, the identification plate is drilled, and when the workbench 200 moves down, the processing of the identification plate is completed. The clamping assembly is slidably arranged on the clamping arms 300. When the workbench 200 moves up and down, the rocker arm 120 swings accordingly. Fig.10 As shown, a first torsion spring 111 is provided between the rocker arm 120 and the mounting frame 110 to facilitate swinging and resetting. Fig.11 As shown, a hinge seat is provided at the top of the rocker arm 120, the top of the rocker arm 120 is hinged to the hinge seat, and the hinge seat is connected to the clamping assembly, such as Figure 3As shown, when the workbench 200 moves up, the two rockers 120 swing toward the middle, driving the clamping assembly to automatically clamp the sign and perform drilling. After the drilling is completed, the workbench 200 moves down, and the rockers 120 swing to both sides to automatically loosen the sign. At this time, the sign can be removed and the next sign can be drilled. The overall realization is convenient and the degree of automation is high, and there is no need to punch holes after manual clamping every time.

[0034] In order to ensure the positioning effect of the identification plate, a placement frame can be set according to the identification plates of the corresponding batch, and the placement frame can be fixedly connected to the workbench 200 to ensure the positioning of the identification plate.

[0035] As a preferred solution, the driving mechanism includes a rotating seat 400 and a limiting member 500, the rotating seat 400 is rotatably connected to the frame 100, the rotating seat 400 is driven by a motor, the rotating seat 400 is provided with a first lever 410 and a second lever 420 staggered from each other, the workbench 200 is provided with a shift block 210 and a first limiting block 220 on the side close to the rotating seat 400, the workbench 200 is provided with a guide groove 230, the frame 100 is provided with a guide block 140, and the guide block 140 matches the guide groove 230; the limiting member 500 is connected to the frame 10 0 rotation connection, a second torsion spring 530 is sleeved on the rotation shaft of the limit member 500, and the two ends of the second torsion spring 530 are respectively connected to the limit member 500 and the frame 100, the limit member 500 includes an integrally formed second limit block 510 and a third lever 520, the first lever 410 is used to move the lever block 210 to move the workbench 200 upward, the first limit block 220 matches the second limit block 510, and is used to limit the height of the workbench 200; the second lever 420 is used to move the third lever 520 to disengage the second limit block 510 from the first limit block 220, and the workbench 200 moves downward.

[0036] The initial state is Figure 3 and Figure 6 As shown, at this time, the workbench 200 is in the initial state, the clamping components are located at both ends of the clamping arms 300, and the swing arms are unfolded to remove the processed identification plates and place the identification plates to be processed;

[0037] The rotating seat 400 starts to rotate counterclockwise. During the rotation, the first lever 410 moves the shifting block 210 on the workbench 200. Figure 6 The state of the critical point of contact between the first lever 410 and the lever block 210 is shown in FIG. 2. As the first lever 410 rotates, the workbench 200 is lifted up, and the workbench 200 moves up in a straight line under the action of the guide block 140 and the guide groove 230 until the first limit block 220 on the workbench 200 contacts the second limit block 510. Figure 7-9As shown, the first limit block 220 and the second limit block 510 are both triangular block structures, and the second limit block 510 is located on the left side of the rotation axis of the limit member 500.

At this time, the third lever 520 rotates clockwise, so that the first limit block 220 falls onto the second limit block 510 to maintain the height of the workbench 200, and drilling is performed synchronously at this time;

[0038] As the rotating seat 400 continues to rotate, when the second lever 420 moves to the critical point of contact with the third lever 520, the second lever 420 drives the third lever 520 to rotate clockwise again. At this time, the workbench 200 automatically falls due to gravity under the action of the guide block 140 and returns to the initial state, thereby removing the processed identification plate and placing the identification plate to be processed.

[0039] The swing arm swings accordingly when the workbench 200 rises and moves downward, thereby achieving synchronous clamping of the identification plate.

The two ends of the spring 313 are respectively connected to the clamping block 320 and the moving block 310.

[0042] like Figure 5As shown, through the arrangement of the moving block 310 and the clamping block 320, when the workbench 200 moves upward, the rocker arm 120 drives the two clamping components to move closer to each other to clamp the identification plate, and the hinged seat on the rocker arm 120 is connected to the bottom of the moving block 310; during the upward movement, the clamping block 320 first contacts the identification plate, and as the workbench 200 moves upward, the spring 313 is compressed, so that the clamping block 320 applies uniform force to clamp the identification plate until the workbench 200 reaches the best clamping state when it is stationary at the highest point, and drilling is performed synchronously, with a good clamping effect.
