Description

Technical Field

[0001] This invention relates to the field of hardness testing technology, and more specifically, to a device and process for testing the hardness of flexible resin boards. Background Technology

[0002] After the production of flexible resin boards is completed, random inspection of the same batch of products is required. Hardness testing is one of the testing steps for flexible resin boards. Most existing hardness testing devices place the flexible resin board on the testing table and then fix and clamp it. However, due to the hardness testing standards, at least five points need to be taken on the flexible resin board for testing. Therefore, the flexible resin board needs to be changed in position for each test, which is a relatively complicated operation. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a flexible resin board hardness testing device and its process, which has the advantage of simple operation.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a flexible resin board hardness testing device, comprising a worktable, a placement plate fixedly installed in the middle of the worktable, a driving assembly fixedly installed at the top of the worktable, and a moving assembly provided at the rear of the worktable; The drive assembly includes a hydraulic cylinder, which is fixedly mounted on the top of the worktable. A movable shaft is fixedly sleeved on the output end of the hydraulic cylinder. A fixing block is fixedly mounted on the bottom end of the movable shaft. An mounting block is sleeved on the bottom end of the movable shaft. A rack is fixedly mounted on the rear side of the mounting block. The moving component includes a slide rail, which is fixedly installed at the rear end of the worktable. A rack is slidably connected to the bottom end of the slide rail, and a connecting frame is fixedly installed at the bottom end of the rack. A moving platform is fixedly installed at the bottom end of the connecting frame. A gear is rotatably connected to the rear end of the worktable, and a gear is fixedly installed at the right end of the gear.

[0005] As a preferred embodiment of the present invention, the mounting block is located below the fixing block and the two are in contact, and the four corners of the fixing block and the mounting block are detachably connected by bolts.

[0006] As a preferred embodiment of the present invention, the rack includes a fixing strip, which is fixedly installed on the rear side of the mounting block. A rotating tooth is rotatably connected to the rear side of the fixing strip. A spring plate and a limiting block are fixedly installed at the rear end of the fixing strip. The spring plate is fixedly connected to the fixing strip and the rotating tooth. The limiting block is located above the rotating tooth.

[0007] As a preferred embodiment of the present invention, the movable platform is slidably connected to the top center of the placement plate, the top surface of the movable platform and the top surface of the placement plate are on the same horizontal plane, and the projection of the movable axis in the vertical direction is located inside the movable platform.

[0008] As a preferred embodiment of the present invention, flattening components are fixedly installed at both ends of the rack one. The flattening components include an extension shaft, a connecting block one is rotatably connected to the surface of the extension shaft, a telescopic rod and a spring are fixedly installed at the bottom end of the connecting block one, a connecting block two is fixedly installed at the bottom end of the telescopic rod and the spring, and a pressure shaft is rotatably connected to the bottom end of the connecting block two.

[0009] In a preferred embodiment of the present invention, the spring is sleeved on the outside of the telescopic rod, and the rack is located on the right side of the spring.

[0010] As a preferred embodiment of the present invention, a limiting shaft is fixedly installed at the front end of the mounting block, and both the left and right sides of the limiting shaft are in contact with the connecting block.

[0011] As a preferred embodiment of the present invention, a pressure sensor is fixedly installed at the bottom end of the movable shaft.

[0012] A testing process for a flexible resin board hardness testing device, the testing process comprising the following steps: The flexible resin board to be tested is placed on the placement plate. The driving component drives the flattening component to move down and press the flexible resin board flat. Then the pressure sensor comes into contact with the flexible resin board and performs hardness detection at the first point. Then the drive component moves upward, and after the flattening component unlocks the flexible resin plate, the drive component moves downward after passing the moving component. At this time, the drive moving component pushes the flexible resin plate forward, placing the second detection point below the pressure sensor. The steps for the second detection point are repeated until all five detection points have been detected, and then the flexible resin plate is removed.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a hydraulic cylinder to drive a moving shaft to move up and down, which in turn moves the mounting block up and down. After the mounting block moves down to perform a hardness test on the flexible resin board, the mounting block is driven to move up. Then, during the second hardness test, the mounting block moves down and drives a rack to rotate a gear, which in turn rotates a gear. The meshing of gear two with rack two drives the moving platform forward, which in turn moves the flexible resin board forward a certain distance, thus placing the second hardness test position below the pressure sensor. The operation is simple and convenient.

[0014] 2. The present invention drives the mounting block to move downward by moving the shaft. When the pressure shaft contacts the flexible resin plate, the pressure shaft will move to both sides under the action of the downward movement of the mounting block. During the movement, the periphery of the area to be tested can be flattened, avoiding the occurrence of warping and wrinkles near the testing area of ​​the flexible resin plate during the testing process. Furthermore, after the flexible resin plate is placed, the testing area can be automatically fixed and clamped. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 8As shown, the present invention provides a flexible resin board hardness testing device, including a worktable 1, a placement plate 2 fixedly installed in the middle of the worktable 1, a drive assembly 3 fixedly installed at the top of the worktable 1, and a moving assembly 4 provided on the rear side of the worktable 1. The drive assembly 3 includes a hydraulic cylinder 31, which is fixedly installed on the top of the worktable 1. A movable shaft 32 is fixedly sleeved on the output end of the hydraulic cylinder 31. A fixed block 33 is fixedly installed on the bottom end of the movable shaft 32. A mounting block 34 is sleeved on the bottom end of the movable shaft 32. A rack 35 is fixedly installed on the rear side of the mounting block 34. The moving component 4 includes a slide rail 41, which is fixedly installed at the rear end of the worktable 1. A rack 42 is slidably connected to the bottom end of the slide rail 41. A connecting frame 43 is fixedly installed at the bottom end of the rack 42. A moving stage 44 is fixedly installed at the bottom end of the connecting frame 43. A gear 45 is rotatably connected to the rear end of the worktable 1. A gear 46 is fixedly installed at the right end of the gear 45.

[0019] The hydraulic cylinder 31 drives the moving shaft 32 to move up and down, which in turn drives the mounting block 34 to move up and down. After the mounting block 34 moves down to perform a hardness test on the flexible resin board, the mounting block 34 is driven to move up. Then, during the second hardness test, the mounting block 34 moves down and drives the gear 45 to rotate via the rack 35, which in turn drives the gear 46 to rotate. The meshing of the gear 46 and the rack 42 drives the moving table 44 to move forward, which in turn moves the flexible resin board forward a certain distance. This allows the second hardness test position to be placed below the pressure sensor 6, saving the time of canceling the clamping and moving of the flexible resin board and then clamping it again. The operation is simple and convenient.

[0020] The mounting block 34 is located below the fixing block 33 and the two are in contact. The four corners of the fixing block 33 and the mounting block 34 are detachably connected by bolts.

[0021] By fixing the fixing block 33 and the mounting block 34 with bolts, the mounting block 34 can be quickly disassembled, replaced, and maintained. When modifying a conventional hardness testing device, the mounting block 34 can be installed by simply welding the fixing block 33 onto the moving shaft 32, making the modification more convenient and efficient.

[0022] Among them, the rack 35 includes a fixing strip 351, which is fixedly installed on the rear side of the mounting block 34. The rear side of the fixing strip 351 is rotatably connected to a rotating tooth 352. A spring plate 353 and a limiting block 354 are fixedly installed at the rear end of the fixing strip 351. The spring plate 353 is fixedly connected to the fixing strip 351 and the rotating tooth 352. The limiting block 354 is located above the rotating tooth 352.

[0023] By setting a rotatable rotating tooth 352, when the mounting block 34 moves upward, the rotating tooth 352 will be blocked by the gear 45 and rotate downward, thereby preventing the gear 45 from rotating. When the mounting block 34 moves downward, the rotating tooth 352 will be blocked by the limiting block 354 and will not be able to rotate upward. Instead, it will mesh with the gear 45 and drive the gear 45 to rotate.

[0024] The movable stage 44 is slidably connected to the top center of the placement plate 2. The top surface of the movable stage 44 is on the same horizontal plane as the top surface of the placement plate 2. The projection of the movable axis 32 in the vertical direction is located inside the movable stage 44.

[0025] To ensure that when the moving shaft 32 moves downward, the area of ​​the flexible resin plate that is pressed by the pressure sensor 6 can always be pressed on the moving platform 44, and that the top surface of the moving platform 44 and the top surface of the placement plate 2 are on the same horizontal plane, the flexible resin plate will not be twisted, and the flexible resin plate will remain horizontal and move smoothly back and forth.

[0026] Among them, flattening components 5 are fixedly installed at both ends of the rack 35. The flattening components 5 include an extension shaft 51. A connecting block 52 is rotatably connected to the surface of the extension shaft 51. A telescopic rod 53 and a spring 54 are fixedly installed at the bottom end of the connecting block 52. A connecting block 55 is fixedly installed at the bottom end of the telescopic rod 53 and the spring 54. A pressure shaft 56 is rotatably connected to the bottom end of the connecting block 55.

[0027] The mounting block 34 is driven to move downward by the moving shaft 32. When the pressure shaft 56 contacts the flexible resin plate, the pressure shaft 56 will move to both sides under the action of the downward movement of the mounting block 34. During the movement, the periphery of the area to be tested can be flattened, avoiding the occurrence of warping and wrinkles near the testing area of ​​the flexible resin plate during the testing process. After the flexible resin plate is placed, the testing area can be automatically fixed and clamped.

[0028] Among them, spring 54 is sleeved on the outside of telescopic rod 53, and rack 2 42 is located on the right side of spring 54.

[0029] The flexible resin board is fixed by applying pressure to it using the elastic force of spring 54. By placing rack 2 42 on the right side of spring 54, the up-and-down movement of mounting block 34 can be prevented from interfering with the back-and-forth movement of rack 2 42.

[0030] Among them, the front end of the mounting block 34 is fixedly mounted with a limiting shaft 7, and both the left and right sides of the limiting shaft 7 are in contact with the connecting block 52.

[0031] By setting the limiting shaft 7 to limit the lower swing of the connecting block 52, it is ensured that the two connecting blocks 52 are in a figure-eight shape when stationary, so that they can move in different directions after the pressure shaft 56 contacts the flexible plate.

[0032] A pressure sensor 6 is fixedly installed at the bottom of the movable shaft 32.

[0033] The pressure sensor 6 is model EVT-14F, and it has a conical pressure head at the bottom. The pressure sensor 6 is used to detect the pressure on the flexible resin board and then calculate the hardness of the current detection area. This is existing technology and will not be described in detail here.

[0034] A testing process for a flexible resin board hardness testing device is as follows: like Figure 1 The image shows the initial state. The flexible resin board to be tested is placed on the placement plate 2, and the rear side of the flexible resin board is in contact with the rear end of the moving stage 44. Hydraulic cylinder 31 drives moving shaft 32 to move downward. When moving shaft 32 moves downward, it drives mounting block 34 to move downward through fixed block 33, which in turn drives pressure shaft 56 to move downward. When pressure shaft 56 contacts flexible resin plate, pressure shaft 56 will press on the surface of flexible resin plate and move to the left and right sides, pressing and flattening the left and right sides of the detection area, and making room for pressure sensor 6. As moving shaft 32 moves downward, pressure sensor 6 contacts flexible resin plate. Pressure sensor 6 detects the applied pressure. When the pressure value reaches the threshold, no more pressure is applied. Then moving shaft 32 moves upward. At this time, observe whether there is any damage, whitening, or irreparable damage on flexible resin plate. If there is no damage, it means the hardness is qualified; otherwise, the hardness is unqualified. After the moving shaft 32 moves upward, the pressure shaft 56 will move in the opposite direction until the connecting block 52 contacts the limiting shaft 7. Then the pressure shaft 56 leaves the flexible resin plate. At this time, the moving shaft 32 continues to move upward. When the rack 35 contacts the gear 45, the rotating tooth 352 will be blocked by the gear 45 and rotate downward. Therefore, the gear 45 will not rotate. When the rack 35 is completely above the gear 45, the mounting block 34 moves downward. At this time, the rotating tooth 352 is blocked by the limiting block 354 and cannot rotate upward. It will mesh with the gear 45, thereby driving the gear 45 and the gear 46 to rotate. Through the meshing of the gear 46 and the rack 42, the moving stage 44 moves forward, thereby pushing the flexible resin plate forward and placing the second detection point below the pressure sensor 6. Repeat the steps for the second test point until all five test points have been tested, then remove the flexible resin board.
