Description

Technical Field

[0001] The utility model belongs to the technical field of back plate clamping, in particular to a clamping device for producing a back plate of an LED display. Background Art

[0002] LED display is a flat panel display with high brightness, low power consumption, wide viewing angle, long life, impact resistance and stable performance. It can display changing numbers, text, graphics and images. The back panel of LED display usually refers to the back support structure or component of the display. During its production, it is often processed by punching, stamping and other processing to meet different usage requirements.

[0003] At present, when punching and stamping the display back panel, it often takes a long time to position the back panel to the predetermined position, which affects the production efficiency. In addition, the manual positioning method also has certain errors, which affects the production quality of the back panel.

[0004] In order to solve the above problems, the present application proposes a clamping device for producing LED display back panels. Utility Model Content

[0005] The purpose of the utility model is to provide a clamping device for producing a back panel of an LED display, which solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a clamping device for producing a back panel of an LED display, comprising: a base, wherein the base is installed inside a processing device by bolts through plate mechanisms on both sides; slide seats for driving the back panel to move are arranged on both sides of the base, a positioning seat for positioning the back panel is arranged inside and at an upper end of the slide seat, and a positioning plate for a processing mechanism thereof is arranged on the upper end of the positioning seat; a grinding wheel for grinding the bottom of the back panel is arranged above one end of the base, a positioning frame for adjusting the use position of the grinding wheel is arranged above one end of the base, a transmission shaft is arranged inside one end of the base, the lower end of the transmission shaft is an electric telescopic mechanism, and a positioning hole for positioning the grinding wheel is opened above one end of the base.

[0008] Furthermore, a top plate supporting a back plate is arranged inside the slide seat, an electric retractor is arranged outside the upper end of the slide seat, and a clamping plate is arranged at one end of the electric retractor for pressing against the back plate to fix it.

[0009] Furthermore, a slide rack is arranged at the lower end of the slide seat, and a transmission screw for spirally mounting the slide rack is arranged inside the base.

[0010] Furthermore, a side plate is provided at the lower end of the positioning seat, and an automatic positioning block is provided at the lower end of the side plate.

[0011] Furthermore, a blocking pad is provided on the inner side of the clamping plate for forming protection close to the back plate.

[0012] Furthermore, a spring pin engaged with the positioning hole is provided inside the positioning frame.

[0013] Furthermore, the position adjustment of the positioning frame is used to drive the grinding wheel to adapt to different processing positions of the back plate.

[0014] The utility model has the following beneficial effects:

[0015] The utility model locates the processing position of the back plate when installing the back plate after the positioning plate corresponds to the punching position, and then directly moves the slide seat so that the clamping block is engaged with the groove inside the base surface, and then the back plate can be driven to move to the predetermined position to form a positioning. Compared with the existing installation method, only one positioning operation is required, and the back plate can be positioned for multiple times in a cycle, which greatly improves the production efficiency and ensures the processing accuracy to improve the production quality of the back plate.

[0016] The utility model uses a grinding wheel that is installed and whose use position is adjusted by a spring pin. When the back plate is recovered, the grinding wheel can be automatically aligned with the processing position of the bottom for grinding to remove burrs and protruding parts. This arrangement can greatly shorten the production cycle of the back plate, adapt to large-scale production operations, and improve the practical performance of the equipment to reduce the investment cost of the equipment.

[0038] A specific application of the operation process of this embodiment is as follows: when in use, first install the base 1 inside the processing equipment, then adjust the positioning seat 3 to a position flush with the processing tool, and then directly place the back plate on the upper end of the slide 2, and align the position to be processed with the positioning plate 4, then drive the transmission screw 13 to drive the slide 2 to move. At this time, the clamping block 15 automatically engages with the groove on the surface of the base 1 after moving to the predetermined position to position the back plate to the predetermined processing position. After this arrangement, the installation time of the back plate can be greatly shortened and the work efficiency can be improved. Furthermore, when the back plate is moved out after processing, the positioning frame 6, which is positioned by the spring pin 17 through the positioning frame 6, can be automatically lifted up to grind the bottom of the back plate when it is moved out to the predetermined position, so as to shorten the subsequent processing steps and improve production efficiency. It is suitable for large-scale production operations and improves the practical performance of the equipment.
