Description

Technical Field

[0001] The present invention relates to the technical field of clamping devices, and more specifically, to an adjustable rotary clamping device for a PSA automatic machine. Background Art

[0002] PSA refers to pressure-sensitive adhesive, a type of adhesive that can be firmly bonded to the adherend under relatively small pressure. In the flexible board industry, PSA specifically refers to a plastic sheet coated with pressure-sensitive adhesive on one side, which is usually used to position the flexible board or for local electrical and mechanical protection. Usually, the PSA pasting process requires positioning support for the product to ensure the position accuracy in the three directions of XYZ before pasting PSA to meet the product PSA pasting position accuracy requirements. Because pasting PSA on the front of the product requires leaving space for pasting, the positioning of the product in the Z direction can only be guaranteed by the bottom support.

[0028] The tops of the two pressing plates 34 are both provided with positioning rods 35, and the repelling sides of the two pressing plates 34 are both provided with upper cover plates 33, and the bottom of the upper cover plate 33 is fixedly connected with a first top plate 37, and a first slider 36 is installed on one side of the first top plate 37. Two first cylinders 32 are installed on the top of the workbench 1, and the two first cylinders 32 correspond to the two pressing plates 34 respectively. The piston rod of the first cylinder 32 is fixedly connected with one side of the first top plate 37, and the first slider 36 is slidably connected to one side of the first cylinder 32. The first cylinder 32 is used to drive the first top plate 37 and the upper cover plate When the first top plate 37 moves up, the first slider 36 is driven to slide on one side of the first cylinder 32, thereby guiding the first top plate 37. When the upper cover plate 33 moves up and down, the pressing plate 34 and the positioning rod 35 are driven to move up and down. When the pressing plate 34 moves up, the pressing plate 34 and the positioning rod 35 are separated from the product 8. When the pressing plate 34 moves down, the pressing plate 34 presses and positions the product 8, and a positioning hole corresponding to the positioning rod 35 is opened on the product 8, so that the positioning rod 35 is inserted into the corresponding positioning hole, thereby improving the effect of pressing and positioning the product 8.

[0029] A second cylinder 38 is installed at the bottom of the workbench 1, and a second slider 39 is slidably connected to one side of the second cylinder 38, and a second top plate 391 is fixedly connected to one side of the second slider 39. A through slot 11 is provided at the bottom of the workbench 1, and the piston rod of the second cylinder 38 and the second top plate 391 both pass through the interior of the through slot 11, and the piston rod of the second cylinder 38 is connected to the top of the second top plate 391, and a fixed block 31 is slidably connected to the top of the second top plate 391. The second cylinder 38 is used to drive the second top plate 391 to move up and down. When the second top plate 391 moves up and down, it drives the second slider 39 to slide on one side of the second cylinder 38, thereby guiding the second top plate 391, and the second top plate 391 drives the fixed block 31 to slide up and down inside the feeding track 2;

[0030] A slide rail 393 is provided on one side of the second top plate 391 close to the second cylinder 38. Two adjustment blocks 392 are slidably connected inside the slide rail 393. The tops of the two adjustment blocks 392 are fixedly connected to the bottom of the fixed block 31.

[0031] A support assembly 5 is installed inside the feeding track 2, and the support assembly 5 includes a support head 51. The support heads 51 are evenly arranged, and multiple support heads 51 are installed on the top of the fixed block 31. An adsorption hole 52 is opened on the top of the support head 51. When the fixed block 31 moves up and down, the fixed block 31 drives the support head 51 to move. The support head 51 is used to push the product 8 to rise, and the adsorption hole 52 is blocked by the product 8.

[0032] The top of the workbench 1 is provided with an adsorption assembly 6, and the adsorption assembly 6 is located on one side of the pressing assembly 3. The adsorption assembly 6 includes a fixing frame 61, which is installed on the top of the workbench 1. A vacuum pressure gauge 62 is evenly installed on one side of the fixing frame 61. A plurality of second air pipes 65 are provided on one side of the fixing block 31. The second air pipes 65 are arranged corresponding to the support head 51, and one end of the second air pipe 65 is connected to the adsorption hole 52 on the support head 51, and the other end of the second air pipe 65 is connected to the first air pipe 63 through a conduit. A vacuum generator 64 is provided on one side, and the vacuum generator 64 is provided corresponding to the vacuum pressure gauge 62. The pipeline of the vacuum generator 64 is connected to the outer wall of the first air pipe 63. Suction is generated by the vacuum generator 64. Under the action of vacuum suction, slight warping deformation less than 2 mm can be adsorbed and corrected, so that the product 8 is flat on the support head 51. The vacuum pressure gauge 62 is connected in series in the vacuum air path, which can monitor the vacuum pressure and set a safety value. When the support head 51 fails to adsorb the product 8 and the pressure value is lower than the safety value, an alarm will be triggered.

[0033] An adjustment mechanism 4 is installed on the opposite side of the clamping assembly 3. The adjustment mechanism 4 includes a fixing plate 43. The fixing plate 43 is fixedly connected to one side of the second top plate 391. An adjusting bolt 41 is threadedly connected to the top of the fixing plate 43. An oil pressure buffer 42 is arranged on the top of the fixing plate 43. The top of the oil pressure buffer 42 passes through the top of the fixing plate 43. The adjusting bolt 41 and the oil pressure buffer 42 can adjust the extended position of the second cylinder 38 to ensure the reference position of the product 8 in the Z direction. Since the fixing block 31 will move upward and the pressing plate 34 will move downward, when the fixing block 31 and the pressing plate 34 are close to each other, the oil pressure buffer 42 will buffer the relative pressure.

[0034] A positioning assembly 7 is installed at one end of the feeding track 2, and the positioning assembly 7 includes a second positioning frame 73, the second positioning frame 73 is arranged on one side of the feeding track 2, and the top of the second positioning frame 73 is threadedly connected with a second adjusting rod 74, and a first positioning frame 71 is installed on one side of the feeding track 2, and a first adjusting rod 72 is arranged on one side of the first positioning frame 71, one end of the first adjusting rod 72 passes through one side of the first positioning frame 71 and is fixedly connected to one side of the second positioning frame 73. When the product 8 is placed inside the feeding track 2, the staff adjusts the first adjusting rod 72 to cause the second positioning frame 73 and the second adjusting rod 74 to be displaced and moved to the top of the product 8. By adjusting the height of the second adjusting rod 74, the bottom end of the second adjusting rod 74 is attached to the top of the product 8, thereby limiting the product 8.

[0035] Example

[0036] Specifically, the staff places the product 8 inside the feeding track 2, and by adjusting the first adjusting rod 72, the second positioning frame 73 and the second adjusting rod 74 are displaced and moved to the top of the product 8. By adjusting the height of the second adjusting rod 74, the bottom end of the second adjusting rod 74 is attached to the top of the product 8, thereby limiting the position of the product 8. The feeding track 2 is used to guide and convey the product 8, and the pressing plate 34 limits the product 8 to prevent the product 8 from being separated from the feeding track 2 during the conveying process.

[0037] The first top plate 37 and the upper cover plate 33 are driven to move up and down by the first cylinder 32. When the first top plate 37 moves up, the first slider 36 is driven to slide on one side of the first cylinder 32, thereby guiding the first top plate 37. When the upper cover plate 33 moves up and down, the pressing plate 34 and the positioning rod 35 are driven to move up and down. When the pressing plate 34 moves up, the pressing plate 34 and the positioning rod 35 are separated from the product 8. When the pressing plate 34 moves down, the pressing plate 34 presses and positions the product 8, and a positioning hole corresponding to the positioning rod 35 is opened on the product 8, so that the positioning rod 35 is inserted into the corresponding positioning hole, thereby improving the effect of pressing and positioning the product 8.

[0038] When the first cylinder 32 is started, the second cylinder 38 is started synchronously, and the second cylinder 38 drives the second top plate 391 to move up and down. When the second top plate 391 moves up and down, it drives the second slider 39 to slide on one side of the second cylinder 38, thereby guiding the second top plate 391. The second top plate 391 drives the fixed block 31 to slide up and down inside the feeding track 2. When the fixed block 31 moves up and down, the fixed block 31 drives the supporting head 51 to move. The supporting head 51 is used to push the product 8 to lift, and the adsorption hole 52 is blocked by the product 8.

[0039] The adjusting bolt 41 and the oil pressure buffer 42 can adjust the extended position of the second cylinder 38 to ensure the reference position of the product 8 in the Z direction. Since the fixed block 31 will move upward and the pressure plate 34 will move downward, when the fixed block 31 and the pressure plate 34 approach each other, the oil pressure buffer 42 will buffer the relative pressure.

[0040] Suction is generated by the vacuum generator 64. Under the action of vacuum suction, slight warping deformation less than 2 mm can be adsorbed and corrected, so that the product 8 is flat on the support head 51. The vacuum pressure gauge 62 is connected in series in the vacuum air path to monitor the vacuum pressure and set a safety value. When the support head 51 fails to adsorb the product 8 and the pressure value is lower than the safety value, an alarm will be triggered.
