Description

Technical Field

[0001] The present invention belongs to the technical field of nickel alloy screen printing stencils, and particularly relates to a device and method for testing the strength of nickel alloy screen printing stencils. Background Art

[0002] Photovoltaic screen printing stencils are used for printing electrodes, and their quality and performance directly affect the photoelectric conversion efficiency of the final product. In order to ensure the quality of the stencils, it is necessary to simulate printing on the stencils to judge the quality of the stencils.

[0003] The problems existing in the prior art are as follows: when the traditional testing device is running, it can only test a single position of the stencil at a time. When testing other positions, it is necessary to use another control machine to turn the testing structure. In this way, when the number of stencils to be tested is large, it will be very time-consuming and laborious, and the efficiency is low. Therefore, we propose a device for testing the strength of nickel alloy screen printing stencils. Summary of the Invention

[0004] The purpose of the present invention is to provide a device and method for testing the strength of nickel alloy screen printing stencils, so as to solve the problems raised in the above background art.

[0005] The present invention is realized as follows. A device for testing the strength of nickel alloy screen printing stencils includes a bottom plate, a vertical plate, and a limiting block. Two groups of the vertical plates are respectively fixedly connected to both sides of the upper surface of the bottom plate. Four groups of the limiting blocks are respectively fixedly connected to the lower surfaces of the two groups of vertical plates. The lower surfaces of the four groups of the limiting blocks are all commonly slidably connected with a clamping assembly. A testing assembly is arranged on the surface of the clamping assembly. The clamping assembly is used for fixing the position of the stencil, and the testing assembly is used for testing the strength of the stencil; The clamping assembly includes a motor, a lead screw, a telescopic rod, and a moving frame. The motor is fixedly connected to the middle part inside the bottom plate. The lead screw is fixedly connected to the output end of the motor. A support frame is arranged on the surface of the lead screw; A threaded block is threadedly connected to the surface of the lead screw. Both sides inside the threaded block are fixedly connected with rotating columns. One end of the surface of the lead screw is provided with a smooth area. Two groups of the telescopic rods are respectively rotatably connected to the surfaces of the two groups of rotating columns; Two groups of connecting rods are respectively rotatably connected to the inside of one end of the two groups of telescopic rods. Four groups of the moving frames are respectively fixedly connected to both ends of the two groups of connecting rods. Limiting plates are slidably connected inside the four groups of the moving frames, and the limiting plates are fixedly connected to the surface of the vertical plate. Corresponding to one end of the two groups of the moving frames, a clamping shell is commonly fixedly connected.

[0006] Preferably, the testing assembly includes a first rotating shaft, a connecting plate, and a turntable. The first rotating shaft is rotatably connected to one end of the lead screw. A placing plate is fixedly connected to the other side of the first rotating shaft. A second rotating shaft is rotatably connected inside the placing plate.

[0007] Preferably, a spring is sleeved on the lead screw. One end of the spring is fixedly connected to a moving plate, and six positioning rods are fixedly connected to the upper surface of the moving plate. The connecting plate is fixedly connected to the upper end of the placing plate.

[0008] Preferably, three sliding shells are fixedly connected to the upper end of the connecting plate. Two sliders are slidably connected inside each of the three sliding shells, and two fixing plates are fixedly connected to the surfaces of the three sliders.

[0009] Preferably, the turntable is movably connected between the six fixing plates. Moving grooves corresponding to the sliders are formed on the surface of the turntable. One end of each of the three sliders is provided with a roller, and holes for positioning the positioning rods are formed on the surface of the turntable.

[0010] A method for testing the strength of a nickel alloy screen printing mesh, applied to the above-mentioned nickel alloy screen printing mesh strength testing device, includes the following steps: S1. According to the usage method, it can be divided into fixing the position of the screen printing mesh and testing the strength. S11. When fixing the position, as the motor runs, it will drive the threaded block to move upward on the surface of the lead screw, thereby using the telescopic rod to pull the moving frame and the clamping shell to move and clamp the screen printing mesh. S12. When testing the strength, as the threaded block moves upward, it will drive the moving plate and the positioning rods to move upward synchronously and be positioned inside the turntable, so that the turntable is driven to rotate by the lead screw, and the roller can be driven to roll back and forth on the surface of the screen printing mesh through the moving groove for strength detection. S2. Complete the operation steps corresponding to each usage method. S21. When the motor runs, it will cause the threaded block to move upward on the surface of the lead screw. During the movement, since the two ends of the telescopic rod are respectively rotatably connected to the rotating column and the connecting rod, the telescopic rod will pull the moving frame to move on the surface of the limiting block, thereby driving the clamping shell to move to fix the position of the screen printing mesh. The limiting plate is used to limit the movement of the moving frame. S22. When the threaded block moves upward, it will push the moving plate and the positioning rod upward, and position the positioning rod inside the turntable. There is no threaded connection between the moving plate and the lead screw. When the threaded block moves to the smooth area on the surface of the lead screw, the threaded block will fix the moving plate on the surface of the first rotating shaft, and the rotational friction of the second rotating shaft is greater than that of the first rotating shaft. Therefore, when the lead screw drives the first rotating shaft to rotate, the first rotating shaft will not drive the second rotating shaft to rotate. So when the moving plate is fixed, the three groups of positioning rods in the middle and the three groups of positioning rods on the outside will be respectively positioned inside the holes in the middle and on the outside of the turntable. The three groups of positioning rods in the middle will pass through the second rotating shaft. At this time, when the lead screw rotates, it will drive the turntable to rotate by using the positioning rods. The spring is used for connecting the moving plate. Due to the design of the moving groove, when the turntable rotates, it will cause the slider to move back and forth inside the sliding shell, thereby driving the roller to roll back and forth on the surface of the wire mesh for testing. The fixing plate is used for supporting the turntable. When the motor drives the lead screw to run in the reverse direction, while the clamping assembly disengages from clamping the wire mesh, the testing assembly will also stop testing the wire mesh. The clamping assembly and the testing assembly operate synchronously.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When in use, the present invention places the wire mesh on the upper ends of the two vertical plates, and then starts the clamping assembly to fix the position of the wire mesh. At the same time, it will drive the testing assembly to operate synchronously, so as to perform strength testing on the surface of the wire mesh, achieving the effect of improving the testing efficiency and preventing inaccurate testing caused by the movement of the wire mesh during testing.

[0012] 2. When the motor operates, the present invention will cause the threaded block to move upward on the surface of the lead screw. During the movement, since the two ends of the telescopic rod are respectively rotatably connected to the rotating column and the connecting rod (which can prevent jamming), the telescopic rod will pull the moving frame to move on the surface of the limiting block, thereby driving the clamping shell to move to fix the position of the wire mesh. The limiting plate is used to limit the movement of the moving frame, achieving the effect of preventing the wire mesh from moving during testing.

[0013] 3. When the threaded block moves upward, it will push the moving plate and the positioning rod upward, and the positioning rod will be positioned inside the turntable. The moving plate is not threadedly connected to the lead screw. When the threaded block moves to the smooth area of the lead screw surface without threads, the threaded block will fix the moving plate on the surface of the first rotating shaft. And the rotational friction of the second rotating shaft is greater than that of the first rotating shaft. Therefore, when the lead screw drives the first rotating shaft to rotate, the first rotating shaft will not drive the second rotating shaft to rotate. So when the moving plate is fixed, the three positioning rods in the middle and the three positioning rods on the outside will be respectively positioned inside the holes in the middle and outside of the turntable. The three positioning rods in the middle will pass through the second rotating shaft. At this time, when the lead screw rotates, it will drive the turntable to rotate by using the positioning rods. The spring is used for connecting the moving plate. Due to the design of the moving groove, when the turntable rotates, it will cause the slider to reciprocate inside the sliding shell, thereby driving the roller to roll back and forth on the surface of the wire mesh for testing. The fixing plate is used for supporting the turntable. When the motor drives the lead screw to run in the reverse direction, while the clamping assembly disengages from clamping the wire mesh, the testing assembly will also stop testing the wire mesh. The clamping assembly and the testing assembly operate synchronously, achieving the effect of effectively improving the testing efficiency of the wire mesh. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail with reference to the accompanying drawings as follows.

[0017] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Embodiment: As Figures 1 to 7 shown, a nickel alloy screen mesh strength testing device provided by an embodiment of the present invention includes a bottom plate 1, vertical plates 3 and limit blocks 5. Two groups of vertical plates 3 are respectively fixedly connected to both sides of the upper surface of the bottom plate 1, and four groups of limit blocks 5 are respectively fixedly connected to the lower surfaces of the two groups of vertical plates 3. A clamping assembly 2 is slidably connected to the lower surfaces of the four groups of limit blocks 5. A testing assembly 4 is arranged on the surface of the clamping assembly 2. The clamping assembly 2 is used for fixing the position of the screen mesh, and the testing assembly 4 is used for testing the strength of the screen mesh; The clamping assembly 2 includes a motor 210, a lead screw 209, a telescopic rod 205 and a moving frame 201. The motor 210 is fixedly connected to the middle of the interior of the bottom plate 1, the lead screw 209 is fixedly connected to the output end of the motor 210, and a support frame 211 is arranged on the surface of the lead screw 209; a threaded block 207 is threadedly connected to the surface of the lead screw 209. Two rotating columns 206 are fixedly connected to both sides inside the threaded block 207. A smooth area 208 is arranged at one end of the surface of the lead screw 209. Two groups of telescopic rods 205 are respectively rotatably connected to the surfaces of the two groups of rotating columns 206; One end of each of the two groups of telescopic rods 205 is rotatably connected to a connecting rod 204 inside. Four groups of moving frames 201 are respectively fixedly connected to both ends of the two groups of connecting rods 204. A limiting plate 202 is slidably connected inside each of the four groups of moving frames 201, and the limiting plate 202 is fixedly connected to the surface of the vertical plate 3. Clamping shells 203 are commonly fixedly connected to one end of the corresponding two groups of moving frames 201; The testing assembly 4 includes a first rotating shaft 405, a connecting plate 401 and a turntable 408. The first rotating shaft 405 is rotatably connected to one end of the lead screw 209, a placing plate 407 is fixedly connected to the other side of the first rotating shaft 405, and a second rotating shaft 406 is rotatably connected inside the placing plate 407; A spring 404 is sleeved on the surface of the lead screw 209. One end of the spring 404 is fixedly connected to a moving plate 403. Six positioning rods 402 are fixedly connected to the upper surface of the moving plate 403. The connecting plate 401 is fixedly connected to the upper end of the placing plate 407; Three sliding shells 409 are fixedly connected to the upper end of the connecting plate 401. Sliders 410 are slidably connected inside each of the three sliding shells 409. Two fixing plates 413 are fixedly connected to the surfaces of each of the three sliders 410; The turntable 408 is movably connected between the six fixing plates 413. A moving groove 412 corresponding to the slider 410 is formed on the surface of the turntable 408. A roller 411 is arranged at one end of each of the three sliders 410. A hole for positioning the positioning rod 402 is formed on the surface of the turntable 408.

[0019] Using the above solution: during use, place the wire mesh on the upper ends of the two sets of vertical plates 3. Subsequently, when starting the clamping assembly 2 to fix the position of the wire mesh, it will drive the test assembly 4 to run synchronously, thereby performing a strength test on the surface of the wire mesh, achieving the effect of improving the test efficiency and preventing inaccurate testing caused by the movement of the wire mesh during testing; When the motor 210 operates, it will cause the threaded block 207 to move upward on the surface of the lead screw 209. During the movement, since the two ends of the telescopic rod 205 are respectively rotatably connected to the rotating column 206 and the connecting rod 204 (which can prevent jamming), the telescopic rod 205 will pull the moving frame 201 to move on the surface of the limiting block 5, thereby driving the clamping shell 203 to move to fix the position of the wire mesh. The limiting plate 202 is used to limit the movement of the moving frame 201, achieving the effect of preventing the wire mesh from moving during testing; When the threaded block 207 moves upward, it will push the moving plate 403 and the positioning rod 402 upward, and make the positioning rod 402 positioned inside the turntable 408. The moving plate 403 is not threadedly connected to the lead screw 209. When the threaded block 207 moves to the smooth area 208 on the surface of the lead screw 209 where there is no thread, the threaded block 207 will fix the moving plate 403 on the surface of the first rotating shaft 405. And the rotational friction of the second rotating shaft 406 is greater than the rotational friction of the first rotating shaft 405. Therefore, when the lead screw 209 drives the first rotating shaft 405 to rotate, the first rotating shaft 405 will not drive the second rotating shaft 406 to rotate. So when the moving plate 403 is fixed, the three central positioning rods 402 and the three outer positioning rods 402 will be respectively positioned inside the central and outer holes of the turntable 408. The three central positioning rods 402 will pass through the second rotating shaft 406. At this time, when the lead screw 209 rotates, it will drive the turntable 408 to rotate by using the positioning rod 402. The spring 404 is used for the connection of the moving plate 403. Due to the design of the moving groove 412, when the turntable 408 rotates, it will cause the slider 410 to reciprocate inside the sliding shell 409, thereby driving the roller 411 to roll back and forth on the surface of the wire mesh for testing. The fixing plate 413 is used for the support of the turntable 408. When the motor 210 drives the lead screw 209 to run in the reverse direction, while the clamping assembly 2 releases the clamping of the wire mesh, the test assembly 4 will also stop testing the wire mesh. The clamping assembly 2 and the test assembly 4 run synchronously, achieving the effect of effectively improving the test efficiency of the wire mesh.

[0020] As Figures 1-7 shown, a method for testing the strength of a nickel alloy mesh wire mesh uses the above-mentioned nickel alloy mesh wire mesh strength testing device, and includes the following steps; S1, according to the usage method, it can be divided into fixing the position of the wire mesh and strength testing; S11. When performing position fixation, as the motor 210 operates, it drives the threaded block 207 to move upward on the surface of the lead screw 209, thereby using the telescopic rod 205 to pull the moving frame 201 and the clamping shell 203 to move and clamp the wire mesh for fixation. S12. When performing strength testing, as the threaded block 207 moves upward, it drives the moving plate 403 and the positioning rod 402 to move upward synchronously and be positioned inside the turntable 408, so that the turntable 408 is driven to rotate by the lead screw 209, and the roller 411 can be driven to roll back and forth on the surface of the wire mesh through the moving groove 412 for strength detection. S2. Complete the operation steps corresponding to each usage method. S21. When the motor 210 operates, the threaded block 207 moves upward on the surface of the lead screw 209. During the movement, since both ends of the telescopic rod 205 are rotatably connected to the rotating column 206 and the connecting rod 204 (which can prevent jamming), the telescopic rod 205 pulls the moving frame 201 to move on the surface of the limiting block 5, thereby driving the clamping shell 203 to move to fix the position of the wire mesh. The limiting plate 202 is used to limit the movement of the moving frame 201, achieving the effect of preventing the wire mesh from moving during testing. S22. When the threaded block 207 moves upward, it pushes the moving plate 403 and the positioning rod 402 upward, and positions the positioning rod 402 inside the turntable 408. The moving plate 403 is not threadedly connected to the lead screw 209. When the threaded block 207 moves to the smooth area 208 on the surface of the lead screw 209 where there is no thread, the threaded block 207 fixes the moving plate 403 on the surface of the first rotating shaft 405, and the rotational friction of the second rotating shaft 406 is greater than that of the first rotating shaft 405. Therefore, when the lead screw 209 drives the first rotating shaft 405 to rotate, the first rotating shaft 405 does not drive the second rotating shaft 406 to rotate. So when the moving plate 403 is fixed, the three groups of positioning rods 402 in the middle and the three groups of positioning rods 402 on the outside will be respectively positioned in the holes in the middle and on the outside of the turntable 408. The three groups of positioning rods 402 in the middle will pass through the second rotating shaft 406. At this time, when the lead screw 209 rotates, it will drive the turntable 408 to rotate by using the positioning rod 402. The spring 404 is used for connecting the moving plate 403. Due to the design of the moving groove 412, when the turntable 408 rotates, the slider 410 will reciprocate inside the sliding shell 409, thereby driving the roller 411 to roll back and forth on the surface of the wire mesh for testing. The fixing plate 413 is used for supporting the turntable 408. When the motor 210 drives the lead screw 209 to run in the reverse direction, while the clamping assembly 2 releases the clamping of the wire mesh, the testing assembly 4 also stops testing the wire mesh. The clamping assembly 2 and the testing assembly 4 operate synchronously, achieving the effect of effectively improving the testing efficiency of the wire mesh.

[0021] The working principle of the present invention: During use, when the motor 210 operates, it causes the threaded block 207 to move upward on the surface of the lead screw 209. During the movement, since both ends of the telescopic rod 205 are rotatably connected to the rotating column 206 and the connecting rod 204 respectively (which can prevent jamming), the telescopic rod 205 will pull the moving frame 201 to move on the surface of the limiting block 5, thereby driving the clamping shell 203 to move to fix the position of the wire mesh. The limiting plate 202 is used to limit the movement of the moving frame 201, achieving the effect of preventing the wire mesh from moving during testing. When the threaded block 207 moves upward, it will push the moving plate 403 and the positioning rod 402 upward, and make the positioning rod 402 positioned inside the turntable 408. The moving plate 403 is not threadedly connected to the lead screw 209. When the threaded block 207 moves to the smooth area 208 on the surface of the lead screw 209 where there is no thread, the threaded block 207 will fix the moving plate 403 on the surface of the first rotating shaft 405, and the rotational friction of the second rotating shaft 406 is greater than that of the first rotating shaft 405. Therefore, when the lead screw 209 drives the first rotating shaft 405 to rotate, the first rotating shaft 405 will not drive the second rotating shaft 406 to rotate. So when the moving plate 403 is fixed, the three central positioning rods 402 and the three outer positioning rods 402 will be respectively positioned inside the central and outer holes of the turntable 408. The three central positioning rods 402 will pass through the second rotating shaft 406. At this time, when the lead screw 209 rotates, it will drive the turntable 408 to rotate by using the positioning rod 402. The spring 404 is used for connecting the moving plate 403. Due to the design of the moving groove 412, when the turntable 408 rotates, it will cause the slider 410 to reciprocate inside the sliding shell 409, thereby driving the roller 411 to roll back and forth on the surface of the wire mesh for testing. The fixing plate 413 is used for supporting the turntable 408. When the motor 210 drives the lead screw 209 to run in the reverse direction, while the clamping assembly 2 releases the clamping of the wire mesh, the testing assembly 4 will also stop testing the wire mesh. The clamping assembly 2 and the testing assembly 4 operate synchronously, achieving the effect of effectively improving the testing efficiency of the wire mesh.

[0022] In summary, for this nickel alloy mesh screen strength testing device, through the structures of the connecting plate 401, positioning rod 402, moving plate 403, spring 404, first rotating shaft 405, second rotating shaft 406, placing plate 407, turntable 408, sliding shell 409, slider 410, roller 411, moving groove 412 and fixing plate 413, it solves the problem that the traditional testing device can only test a single position of the wire mesh during operation. When testing other positions, it is necessary to control another machine to turn the testing structure. In this way, when the number of wire meshes to be tested is large, it is very time-consuming and laborious, and the efficiency is low.

The limit plate (202) is used to limit the movement of the moving frame (201); S22, when the threaded block (207) moves upward, it pushes the moving plate (403) and the positioning rod (402) to move upward, and positions the positioning rod (402) inside the turntable (408). There is no threaded connection between the moving plate (403) and the screw rod (209). When the threaded block (207) moves to the smooth area (208) on the surface of the screw rod (209), the threaded block (207) fixes the moving plate (403) on the surface of the first rotating shaft (405), and the rotational friction force of the second rotating shaft (406) is greater than the rotational friction force of the first rotating shaft (405). Therefore, when the screw rod (209) drives the first rotating shaft (405) to rotate, the first rotating shaft (405) does not drive the second rotating shaft (406) to rotate. Therefore, when the moving plate (403) is fixed, the three sets of positioning rods (402) in the middle and the three sets of positioning rods (402) on the outside are fixed. ) will be positioned in the middle and outer holes of the turntable (408) respectively, and the three sets of positioning rods (402) in the middle will pass through the second rotating shaft (406). At this time, the screw rod (209) will rotate to drive the turntable (408) to rotate using the positioning rod (402). The spring (404) is used to connect the movable plate (403). Due to the design of the movable groove (412), when the turntable (408) rotates, the slider (410) will reciprocate inside the sliding shell (409), thereby driving the roller (411) to roll back and forth on the surface of the wire mesh for testing. The fixed plate (413) is used to support the turntable (408). When the motor (210) drives the screw rod (209) to run in the reverse direction, the clamping assembly (2) disengages from the clamping of the wire mesh, and the test assembly (4) also stops testing the wire mesh. The clamping assembly (2) and the test assembly (4) run synchronously.
