Description

Technical Field

[0001] The utility model relates to the field of polarizer processing, in particular to a double-seat special-shaped polarizer edge grinding machine. Background Technique

[0002] A polarizer is an optical device that can suppress specific vibration directions in light waves and is commonly used in fields such as optical lenses, cameras, and liquid crystal displays. A polarizer edge grinding machine is a processing machine for polarizers. During the production and processing of polarizers, they generally need to be positioned and fixed first, and then grinding begins. Some polarizer products need to be drilled after grinding. For example, the polarizer of a mobile phone display module needs to be drilled at the camera position. Currently, most edge grinding machines on the market do not have a tool magazine, resulting in the inability to automatically change tools. Moreover, the edge grinding machine has a single function. Obviously, adding a tool magazine to a numerical control machine tool to enable the machine tool to achieve the function of automatically changing tools is not realistic and also increases the manufacturing cost. In the case where automatic tool change cannot be achieved, only manual tool change can be carried out. After the polarizer completes the grinding process, the machine needs to be paused to replace the tool, and then the polarizer is drilled, which is time-consuming and laborious and affects the production speed. Summary of the Invention

[0003] An object of the utility model is to provide: a double-seat special-shaped polarizer edge grinding machine, which solves the technical problem of waste of production time caused by the lack of a drilling function in the existing edge grinding machine and manual tool change.

[0004] The technical solution of the utility model is realized as follows: a double-seat special-shaped polarizer edge grinding machine includes a frame. On both sides of the frame, two groups of vertically arranged workbench slide rails are respectively installed. At one end of the two groups of workbench slide rails, two groups of positioning components for pressing the polarizer are respectively arranged, and at the other end, two groups of jigs are respectively installed. Outside the two groups of workbench slide rails, a U-shaped support frame is installed. The U-shaped support frame separates the two groups of positioning components on the workbench slide rails from the two groups of jigs. On the side of the U-shaped support frame located on the jig, a transversely slidable first slide rail is installed. On one side of the first slide rail, a second slide rail perpendicular to the first slide rail is installed. The sliding component of the second slide rail is connected to the main shaft. The main shaft includes a grinding main shaft and a drilling main shaft assembly.

[0005] Further, the two groups of positioning components include a positioning frame. Two sliding seats are transversely arranged on the positioning frame. On the two sliding seats, two groups of positioning cylinders that can extend towards the jig direction are respectively installed. The connecting ends of the two groups of positioning cylinders vertically extend out of the positioning plate. One side of the two sliding seats is respectively connected to two groups of positioning motors.

[0006] Furthermore, both sets of jigs are composed of a base plate, a bidirectional driving component, a left clamping jaw, a right clamping jaw, a fixture, a fixture support frame, and a lifting slide group. The bidirectional driving component is horizontally arranged on the base plate, and two sets of lifting slide groups are respectively installed at both ends of the bidirectional driving component. The left clamping jaw and the right clamping jaw are respectively installed at the tops of the two sets of lifting slide groups. The fixture support frame is installed in the middle of the bidirectional driving component, and the fixture is installed on the fixture support frame. By adjusting the horizontal sliding through the bidirectional driving component and controlling the lifting of the left clamping jaw and the right clamping jaw by the lifting component on the bidirectional driving component, the left clamping jaw and the right clamping jaw can alternately press the fixture.

[0007] Furthermore, the bidirectional driving component includes a bidirectional cylinder located in the middle of the bidirectional driving component, and the telescopic rods at both ends of the bidirectional cylinder are respectively connected to the sliders located at both ends of the bidirectional cylinder.

[0008] Furthermore, the fixture is also provided with a convex column extending upward.

[0009] Furthermore, the left clamping jaw and the right clamping jaw are provided with holes that are engaged with the convex column.

[0010] Furthermore, a spindle box fixedly installed on the second slide rail is also provided outside the main spindle, and the main spindle protruding from the working area of the main spindle is installed inside the spindle box.

[0011] Furthermore, the drilling spindle assembly includes a drilling spindle, a drilling spindle slide group, and a drilling cylinder. The drilling cylinder and the drilling spindle slide group are vertically installed on the inner wall of the spindle box. The drilling cylinder is connected to one end of the drilling spindle slide group, and the other end of the drilling spindle slide group is fixedly installed with the drilling spindle.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] 1. A drilling spindle is added on one side of the grinding spindle, and the drilling process and the grinding process can be carried out simultaneously without pausing the machine to replace the tool, reducing the process time and saving the manufacturing cost at the same time.

[0014] 2. Two sets of jigs are arranged in the working area. The two sets of jigs can be used separately or simultaneously. After the main spindle finishes working in one working area, it will move to another working area to continue working, increasing the workpiece capacity, reducing the time for manually placing workpieces, and improving the manufacturing time.

[0015] 3. The two sets of jigs have independent positioning components, effectively improving the accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Further, each of the two sets of jigs 4 is composed of a base plate 41, a bidirectional driving assembly 42, a left clamping jaw 43, a right clamping jaw 44, a fixture 45, a fixture support frame 46, and a lifting slide group 47. The bidirectional driving assembly 42 is horizontally arranged on the base plate 41. Two sets of lifting slide groups 47 are respectively installed at both ends of the bidirectional driving assembly 42. The left clamping jaw 43 and the right clamping jaw 44 are respectively installed at the tops of the two sets of lifting slide groups 47. The fixture support frame 46 is installed in the middle of the bidirectional driving assembly 42, and the fixture 45 is installed on the fixture support frame 46. By adjusting the horizontal sliding through the bidirectional driving assembly 42 and controlling the lifting of the left clamping jaw 43 and the right clamping jaw 44 by the lifting assembly 47 on the bidirectional driving assembly 42, the left clamping jaw 43 and the right clamping jaw 44 can alternately press the fixture 45.

[0024] Further, the bidirectional driving assembly 42 includes a bidirectional cylinder 421 located in the middle of the bidirectional driving assembly 42. The telescopic rods at both ends of the bidirectional cylinder 421 are respectively connected to the sliders 422 located at both ends of the bidirectional cylinder 421.

[0029] The working principle of this embodiment: Two sets of workbench slide rails 2 are installed on the frame 1. Two sets of jigs 4 are installed at one end of the two sets of workbench slide rails 2, and two sets of positioning components 3 for assisting the positioning of the two sets of jigs 4 are installed at the other end. A U-shaped support frame 5 is installed outside the two sets of jigs 4. A horizontally sliding first slide rail 51 is installed on the side of the U-shaped support frame 5 above the jig 4.

The spindle box 7 is installed on the second slide rail 52, and the grinding spindle 61 and the drilling spindle 621 are installed in the spindle box 7;

[0030] When drilling, due to the preset position parameters + combined with CCD vision imaging, precise drilling is performed on the polarizer. Only after the left clamping jaw 43 and the right clamping jaw 44 are simultaneously pressed against the fixture 45 can the polarizer be drilled.

[0031] During edge grinding, the laterally arranged sliding seat 32 is driven by the positioning motor 35 to position the lateral position of the polarizer. Then, through the drive of the positioning cylinder 33, the longitudinal position of the polarizer is positioned to achieve precise positioning. The edge of the polarizer is ground. Subsequently, the left clamping jaw 43 first presses one side of the jig 45, and the other side is polished. Then, the sides are exchanged. The right clamping jaw 44 presses the polished side, and then the unpolished side is polished.

[0032] During edge grinding on the other side, the left clamping jaw 43 first presses tightly on the jig 45, and the right clamping jaw 44 moves onto the jig 45. The right clamping jaw 44 and the jig 45 are pressed together through the lifting assembly 47 until the hole 48 on the right clamping jaw 44 passes through the convex post 451 on the hole jig 45 for a tight fit. Then, the lifting assembly 47 controls the left clamping jaw 43 to lift and move away to complete the side exchange, and finally grinding is performed.

[0033] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention are equivalent replacement methods and are all included in the protection scope of the present invention.
