Description

Technical Field

[0001] The present application relates to the field of test piece grinding equipment, and in particular to a high-precision plane grinder for test pieces. Background Art

[0002] Test pieces are used for processing technology inspection and processing cleanliness inspection, and are often used in the field of semiconductor packaging and testing processes.

[0003] During the test, the surface of the test piece is required to be flat and there must not be any uneven areas. Therefore, after the test piece is processed and before the test, the test piece needs to be polished. At present, when polishing the test piece, a grinder is often used to polish the test piece. However, when the tooling on the traditional grinder fixes the test piece, the clamping force of the tooling on the test piece will cause wear or bending deformation of the surface of the test piece.

[0004] Therefore, there is an urgent need for a test piece grinding device that can effectively reduce unnecessary wear and deformation on the surface of the test piece. Utility Model Content

[0005] In order to effectively avoid unnecessary wear and bending deformation on the surface of the test piece caused by grinding, the present application provides a high-precision flat grinder for the test piece.

[0006] The present application provides a high-precision plane grinding machine for test pieces, which adopts the following technical solution:

[0007] A high-precision plane grinder for test pieces comprises a machine body and a grinding assembly arranged above the machine body, wherein the machine body is provided with a base, a placement platform is fixedly arranged below the grinding assembly, and the surface of the placement platform is magnetic.

[0008] By adopting the above technical solution, by setting the surface of the placing platform to have a magnetic structure, it is convenient to magnetically attract the test piece placed on the placing platform, so that the test piece is fixed on the placing platform, thereby effectively avoiding unnecessary wear and bending deformation on the surface of the test piece caused by wear-through.

[0009] Preferably, a workbench is provided between the machine body and the base, and a second driving assembly is provided between the workbench and the base, and the second driving assembly is used for driving the base to move parallel to the grinding direction.

[0010] By adopting the above technical solution, since the grinding component is basically in the same position during the grinding process, it is necessary to drive the test piece to reciprocate through the second driving component to ensure that the same horizontal surface of the test piece can be polished evenly, thereby effectively improving the overall grinding accuracy and grinding effect of the device.

[0011] Preferably, the second driving assembly comprises a cylinder, which is horizontally arranged on one side of the workbench and is flush with the grinding direction, and the output end of the cylinder is fixedly connected to the bottom of one side of the base.

[0012] By adopting the above technical solution, the cylinder is used to drive the base to perform reciprocating motion parallel to the grinding direction, so that the surface of the test piece can be evenly ground, and the grinding effect of the device is further improved.

[0013] Preferably, guide rails are provided on both sides of the base, and guide blocks are provided on the workbench, and the guide blocks are slidably provided in the corresponding guide rails.

[0015] Preferably, a stopper is provided at each end of both ends of each guide rail.

[0016] By adopting the above technical solution, the setting of the stopper can effectively avoid the problem of the base losing control and detaching from the guide rail during the reciprocating motion.

[0017] Preferably, a first driving assembly is provided between the workbench and the machine body, and the first driving assembly is used to drive the workbench to move perpendicularly to the grinding direction.

[0018] By adopting the above technical solution, since the width of the grinding wheel is smaller than the width of the test piece, the first driving component drives the workbench to move perpendicular to the grinding direction, so that the surface of the test piece can be polished, effectively improving the grinding effect of the device.

[0019] Preferably, the first driving component includes a slide groove opened at the bottom of the workbench, the opening direction of the slide groove is perpendicular to the grinding direction, the bottom of the workbench is slidably connected to the machine body through the slide groove, an adjusting screw is rotatably arranged in the slide groove, and the adjusting screw is threadedly connected to the part of the machine body located in the slide groove.

[0020] By adopting the above technical solution, the workbench is driven to move forward and backward by rotating the adjusting screw, thereby realizing the movement adjustment of the workbench perpendicular to the grinding direction, further improving the grinding effect of the device.

[0021] Preferably, an adjusting hand wheel is coaxially arranged at one end of the adjusting screw, and a handle is arranged at a side of the adjusting hand wheel away from the adjusting screw.

[0022] By adopting the above technical solution, the handle drives the rotation of the adjusting hand wheel, thereby effectively improving the operating convenience of the staff.

[0023] Preferably, the grinding assembly includes a mounting base vertically arranged on the machine body, an adjustment bracket is slidably arranged on the mounting base, the adjustment bracket is slidably connected to the mounting base through a screw structure, and the moving stroke is perpendicular to the placement platform, a grinding wheel is rotatably arranged on the adjustment bracket, and a driving motor for driving the grinding wheel to rotate is arranged on the adjustment bracket.

[0024] By adopting the above technical solution, the height of the adjustment bracket can be adjusted conveniently through the screw rod structure, thereby facilitating the adjustment of the height of the grinding wheel, thereby improving the applicability of the device.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. By setting the surface of the placement platform to have a magnetic structure, it is convenient to magnetically attract the test piece placed on the placement platform, so that the test piece is fixed on the placement platform, thereby effectively avoiding unnecessary wear and bending deformation on the surface of the test piece caused by wear-through;

[0027] 2. The second driving assembly drives the test piece to reciprocate, ensuring that the same horizontal surface of the test piece can be polished evenly, effectively improving the overall polishing accuracy and polishing effect of the device;

[0028] 3. The guide block guides the base during movement, thereby preventing the base from deviating during movement, thereby effectively improving the stability of the base during reciprocating movement;

[0029] 4. The first driving assembly drives the workbench to move perpendicularly to the grinding direction, so that the surface of the test piece can be ground, effectively improving the grinding effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS
