Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a drilling device for processing a display back panel. Background Art

[0002] Display is also commonly called monitor. Display is an I / O device of computer, that is, input and output device. It is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye. According to the different manufacturing materials, it can be divided into: cathode ray tube display, plasma display, liquid crystal display, etc. The display backplane is a component of the display. When processing the display backplane, it is necessary to directly punch the display backplane, so a drilling device is needed.

[0003] An existing drilling device for processing a display back panel (especially disclosed in the Chinese utility model patent with application number 202120022484.5) is provided, which has a plate groove and a slide groove on a processing table, and a slider is installed in the slide groove through a first lead screw, and the slider is connected to a supporting vertical rod through a damping shaft, and the supporting vertical rod is connected to a sliding cross rod through a second lead screw, and the sliding cross rod is connected to a mounting plate for placing a second motor and a drill bit through a first electric push rod, so that when drilling a hole in the display back panel on the processing table, the position of the drill bit can be moved laterally and longitudinally and rotated horizontally, so that the drill bit can reach any position of the back panel for drilling, and at the same time, a fixed clamping mechanism is provided on the outside of the drill bit, and the fixed clamping mechanism can vertically clamp the four sides of the drilling position of the back panel when the drill bit is pressed down to drill.

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

When the four electric push rods push the supporting mold 2 to move upward, the two arc-shaped pressing seats 506 will abut against the two sides of the drilled holes on the back plate. As the supporting mold 2 continues to move upward, the pressure generated by it will cause the telescopic rod 505 and the energy-absorbing spring 507 to be compressed and deformed to generate a reaction force acting on the four adaptive support components 3, so that the support seat 2 302 with a plurality of rubber anti-skid teeth 306 on the top slides on the support seat 1 301. The tension generated by the four adaptive support components 3 during sliding cooperates with the pressure applied to the back plate by the plurality of rubber anti-skid teeth 306 and the two arc-shaped pressing seats 506 to complete the positioning of the back plate, avoiding the situation where the back plate position is slightly offset due to vibration, thereby improving stability, facilitating later installation, and having strong practicality.

When the drilling is completed, the four electric push rods are started to pull the supporting mold 2 downward, thereby relieving the pressure applied to the top of the back plate, and the support seat 2 302 is pushed to slide on the top of the support seat 1 301 through multiple return springs 305. The four support seats 2 302 complete the lifting of the back plate, so that the staff can remove the back plate from the supporting mold 2, which simplifies the work process and is more practical.

[0028] It is worth mentioning that in order to complete the displacement of the drill bit 503, so as to perform drilling processing at different positions on the back plate, see Figure 1 , Figure 3 , Figure 4 A drilling assembly 4 is slidably provided on the top of the workbench 1, and the drilling assembly 4 includes a bracket 401.

A servo motor 403 is connected to one end of the screw rod 402 extending out of the rectangular groove, and the servo motor 403 is fixedly installed on one side of the bracket 401. A slider 404 slidably arranged in the rectangular groove is threadedly installed on the outer edge surface of the screw rod 402. The mounting frame 501 is welded and fixed to the top of the slider 404, and the two sides of the bottom end of the bracket 401 are centrally constructed with a slider 405 installed in the sliding groove, and one side of the slider 405 is centrally provided with an inner thread hole for the screw rod 6 to be threaded and installed, and the two sides of the top of the workbench 1 are provided with sliding grooves, and the screw rod 6 is rotatably installed between the two sides of the sliding groove through bearings, and one end of the screw rod 6 extending out of the sliding groove is connected to a servo motor 7 fixedly set on one side of the workbench 1, and the two screw rods 6 are driven to rotate by starting the servo motor 7, so as to drive the bracket 401 to move through the two screw rods 6 and the two sliders 405, and then the screw rod 402 is driven to rotate by the servo motor 403, so as to drive the slider 404 connected to the mounting frame 501 to move through the screw rod 402, so as to move the motor 502 equipped with the drill bit 503 to the position just above the drilling position on the back plate, so as to facilitate the subsequent drilling;

Apply force, so that the support seat 2 302 with multiple rubber anti-skid teeth 306 on the top slides on the support seat 1 301, and the tension generated by the four adaptive support components 3 when sliding cooperates with the pressure applied to the back plate by the multiple rubber anti-skid teeth 306 and the two arc-shaped pressing seats 506 to complete the positioning of the back plate, so that the motor 502 drives the drill bit 503 to drill holes in the back plate. When drilling, it is possible to avoid slight displacement of the back plate position due to vibration. When the drilling is completed, the four electric push rods are started again to pull the supporting mold 2 downward, thereby releasing the pressure applied to the top of the back plate, and the multiple reset springs 305 push the support seat 2 302 to slide on the top of the support seat 1 301, and the four support seats 2 302 complete the lifting of the back plate, so that the staff can remove the back plate from the supporting mold 2, which simplifies the work process, has high stability and strong practicality.
