Description

Technical Field

[0001] The utility model belongs to the technical field of hundred-grid testing, and in particular relates to an adhesive tape tearing device used for hundred-grid testing. Background Art

[0002] The 100-grid test is the most basic test item for evaluating the surface adhesion performance of parts by vehicle manufacturers, paint manufacturers and surface treatment manufacturers. Usually, a special tool is used to draw multiple small grids on the surface of the test sample during the test, and the grid spacing is set according to the coating thickness. Finally, the quality of the product is evaluated by evaluating the amount of material adhered to the tape in the grid. At present, since the 100-grid test process is manually operated, there is considerable uncertainty in the tape removal environment. In the process of manually removing the tape, the angle and speed of each tape removal cannot be guaranteed to be consistent, which leads to deviations in the test results. Utility Model Content

[0003] In order to solve the problem described in the background art that the angle and speed of manual tape removal cannot be guaranteed to be consistent each time, which leads to deviation in the test results, the utility model proposes the following technical solutions:

[0004] A tape tearing device for a 100-grid test is arranged on a test bench, and comprises: a positioning plate, a moving device, a retaining frame and a clamping device; the positioning plate is fixedly arranged on the test bench, the moving device comprises a fixed part and a moving part, the fixed part is fixedly arranged on the surface of the positioning plate, and the moving part can be movably arranged on the surface of the fixed part relative to the test bench; one side of the retaining frame is fixedly arranged on the moving part, and the other side of the retaining frame is fixedly connected to the clamping device; when performing a 100-grid test, after the clamping device clamps the tape, the moving device drives the retaining frame to move relative to the test bench, thereby completing the tape tearing action.

[0005] Wherein, the positioning plate is arranged to be inclined relative to the table top of the test bench.

[0006] Furthermore, the clamping device includes a first part and a second part that are hingedly connected; the first part and the second part can rotate at the center of a circle at a hinge point, and when one end of the first part and one end of the second part rotate toward each other, the other end of the first part and the other end of the second part jointly clamp the tape; when one end of the first part and one end of the second part rotate relative to each other, the other end of the first part and the other end of the second part release the fixation of the tape.

[0007] Furthermore, in the clamped state, an angle exists between the end surfaces of the first part and the second part abutting against each other and the table surface of the test table.

[0008] Furthermore, the angle between the positioning plate and the table top of the test bench is 45°.

[0009] Beneficial effect: The utility model simulates the manual action of tearing off the tape during the 100-grid test by driving the clamping device through the moving device. Under the force of the moving device in a fixed direction, the tape is torn off as the moving device moves. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 The present invention is a tape tearing device for a hundred-grid test according to an embodiment of the present invention.

[0014] Reference Figure 1 According to an embodiment of the utility model, a tape tearing device for a hundred-grid test is arranged on a test bench 1, including: a positioning plate 2, a moving device 3, a retaining frame 4 and a clamping device 5. The positioning plate 2 is fixedly arranged on the test bench 1, and the moving device 3 includes a fixed part 31 and a moving part 32, the fixed part 31 is fixedly arranged on the surface of the positioning plate 2, and the moving part 32 can be movably arranged on the surface of the fixed part 31 relative to the test bench 1. One side of the retaining frame 4 is fixedly arranged on the moving part 32, and the other side of the retaining frame 4 is fixedly connected to the clamping device 5. When performing a hundred-grid test, after the clamping device 5 clamps the tape, the moving device 3 drives the retaining frame 4 to move relative to the test bench 1, thereby completing the tape tearing action.

[0015] Specifically, the moving device 3 is a linear moving device 3 driven by a motor, a back plate is vertically fixed on the table top of the test bench 1, and the narrow surface of the positioning plate 2 is vertically and fixedly arranged on the surface of the back plate. The table top of the test bench 1 is horizontal, and there is an angle between the wide surface of the positioning plate 2 and the table top of the test bench 1. Among them, the fixing part 31 is fixedly arranged on the positioning plate 2 in parallel with the wide surface of the positioning plate 2, and the moving direction of the moving part 32 is the same as the extension direction of the positioning plate 2.

[0016] Furthermore, the clamping device 5 includes a first part 51 and a second part 52 which are hingedly connected. The middle part of the first part 51 and the middle part of the second part 52 are hingedly connected, and with the hinge point as the boundary, one end on the left side of the first part 51 and one end on the left side of the second part 52 are the clamping end, and one end on the right side of the first part 51 and one end on the right side of the second part 52 are the operating end. When performing the hundred-grid test, the relative position of the first part 51 and the second part 52 at the operating end is changed, so that the clamping end releases or clamps the tape.

[0017] When the right end of the first part 51 and the right end of the second part 52 move relative to each other, the left end of the first part 51 and the left end of the second part 52 clamp the adhesive tape together. When the right end of the first part 51 and the right end of the second part 52 move toward each other, the left end of the first part 51 and the left end of the second part 52 release the clamped adhesive tape.

[0018] Furthermore, there is an angle between the end face of the clamping end and the table top of the test bench 1. Preferably, in this embodiment, the angle between the end face of the clamping end and the table top of the test bench 1 is 45°, and the angle between the wide surface of the positioning plate 2 and the table top of the test bench 1 is also 45°. In other embodiments, the angle is an acute angle. During the hundred-grid test, after the operator sticks the tape on the surface of the product to be tested, one end of the tape needs to be clamped by the operator using the clamping device 5. After the tape is pasted, the moving device 3 is started, and the tape is torn off as the moving device moves.

[0019] In summary, the utility model simulates the manual tape tearing action during the 100-grid test by driving the clamping device through the moving device. Under the force of the moving device in a fixed direction, the tape is torn off as the moving device moves.
