[0071] Embodiment 1

[0072] As Figures 1 to 4 shown, this embodiment discloses a clamping and aligning structure, which can be applied to 300x300 and 300x400 small coating machine equipment for clamping and positioning the component to be clamped and aligned. Taking the substrate 5 as the component to be clamped and aligned as an example, this embodiment will be described.

[0073] The clamping and aligning structure includes a driving assembly, a clamping assembly, and a first buffer assembly. The driving assembly has two telescopic ends. A pair of clamping assemblies are provided. The two clamping assemblies are located on opposite sides of the component to be clamped and aligned. Each clamping assembly is respectively connected to a telescopic end, and the two clamping assemblies move towards or away from the component to be clamped and aligned under the drive of the driving assembly. A pair of first buffer assemblies are provided. The first buffer assembly has a telescopic end and a fixed end. The fixed end of the first buffer assembly is arranged on the clamping assembly. The telescopic end of the first buffer assembly extends out from the clamping assembly along the clamping direction. The first buffer assembly is adapted to slow down the clamping speed of the clamping assembly.

[0074] In the above-mentioned clamping structure, the first buffer assembly is arranged on the clamping assembly, and the first buffer assembly extends from the clamping assembly along the clamping direction. Thus, when clamping the substrate 5, before the substrate 5 contacts the clamping assembly, the first buffer assembly first abuts against the side wall of the positioning table 3, and then the first buffer assembly buffers the clamping assembly. Under the action of the first buffer assembly, the clamping speed of the clamping assembly will decrease, preventing the problem of hard collision between the clamping assembly and the substrate 5 due to too fast clamping speed when clamping the substrate 5. Then the substrate 5 will contact the clamping assembly, and then the two oppositely arranged clamping assemblies will perform clamping and positioning.

[0075] In some embodiments, the first buffer assembly includes at least one oil pressure buffer. The main function of the oil pressure buffer is to achieve the balance and buffering effect of oil pressure by using oil to achieve the effect of stable movement.

[0076] The existing clamping structure only relies on the cylinder to clamp the substrate 5, which cannot ensure that the substrate 5 is clamped in place. There will be errors during the clamping process of the substrate 5, and its positioning accuracy cannot be guaranteed, nor can its positioning accuracy range be adjusted. To solve this technical problem, in some embodiments, the oil pressure buffer is a stroke-adjustable oil pressure buffer. The adjustment method of the oil pressure buffer can include two methods: manual and automatic. Manual adjustment is usually carried out through the manual or mechanical adjustment device equipped with the hydraulic buffer. The damping coefficient can be changed by rotating or adjusting the handle or dial to achieve the required damping effect. Automatic adjustment is achieved through the sensor system built into the hydraulic buffer. It can monitor the impact force magnitude and speed and adjust the damping coefficient according to the system requirements. The automatic adjustment method usually requires setting certain parameters on the equipment to achieve the required damping effect.

[0077] In this embodiment, the clamping position is mainly adjusted by rotating and twisting the oil pressure buffer to make its clamping and positioning accuracy accurate, and the accuracy range is adjustable. After the position is adjusted, it can be locked with two nuts, and its position accuracy will not change due to external influences.

[0078] Hereinafter, the present invention will be described by taking the front and rear positioning assemblies 1 as the clamping structure as an example.

[0079] In some embodiments, the clamping assembly includes a first positioning block 138 and a first retaining column 139. The first positioning block 138 is arranged horizontally. There are at least two first retaining columns 139, and the first retaining columns 139 are vertically spaced on the positioning block. More specifically, the first retaining columns 139 are installed in the round holes 1381 of the first positioning block 138 and locked with screws. In this embodiment, when the first retaining column 139 contacts the substrate 5, the first retaining column 139 positions the side wall of the substrate 5.

[0080] In some embodiments, the driving assembly includes two first sliding table cylinders 11 symmetrically arranged in a split manner. The piston rod end of each first sliding table cylinder 11 is locked and connected to a first sliding table cylinder movable plate 12 by a first screw. The first sliding table cylinder 11 is located above the first sliding table cylinder movable plate 12. The first sliding table cylinder movable plate 12 is connected with a first lifting assembly 13, and the first lifting assembly 13 is adapted to drive the clamping assembly and the first buffer assembly to lift. In this embodiment, the first sliding table cylinder 11 moves to drive the first sliding table cylinder movable plate 12 to move back and forth, so as to realize the function of front and back clamping and positioning. The clamping structure is set as a jacking and clamping structure, so that the clamping assembly and the first buffer assembly have the lifting function.

[0081] In some embodiments, the first lifting assembly 13 includes a first limit block 133, a first lifting cylinder 137, a first lifting cylinder mounting plate 131, a first linear guide rail 135, a first guide block 136 and a first limit strengthening block 132.

[0082] The first limit strengthening block 132, the first linear guide rail 135 and the first lifting cylinder 137 are locked to the first lifting cylinder mounting plate 131 by screws. The oil buffer is screwed into the screw hole of the first limit block 133 by rotation. Before the lifting assembly starts, rotate and twist the oil buffer to adjust the position for clamping and limiting, so that the clamping and positioning accuracy is accurate and the accuracy range is adjustable. After the position is adjusted, lock it with two nuts, and its position accuracy will not change due to external influences. The telescopic end of the first lifting cylinder 137 is connected to the first limit block 133 through a first floating joint 1310. The first floating joint 1310 is stuck in the U-shaped groove 1382 of the first positioning block 138. The first limit block 133 is locked to the first positioning block 138 by screws. One side of the first lifting cylinder mounting plate 131 is fixedly connected to the first sliding table cylinder movable plate 12 by a second screw, and the other side of the first lifting cylinder mounting plate 131 is connected to the side wall of the first lifting cylinder 137. The first linear guide rail 135 is arranged on the first lifting cylinder mounting plate 131. The first guide block 136 is connected to the first limit block 133 and is slidably assembled on the first linear guide rail 135. The first limit strengthening block 132 is connected to the first lifting cylinder mounting plate 131 and limits the lifting position of the first lifting cylinder 137.

[0083] The original lifting assembly only relies on the cylinder to realize lifting, and it will wobble during the lifting process, and its strength is insufficient to ensure its stability. In this embodiment, the first linear guide rails 135 are added on both sides of the first lifting cylinder 137. During lifting, the first floating joint 1310 installed on the first lifting cylinder 137 drives the first positioning block 138 to move up and down. The first linear guide rails 135 enhance the strength of the first lifting assembly 13 and will not wobble during the lifting process.

[0084] When the first lifting component 13 completes the ascending movement, the first sliding table cylinder 11 starts to move forward, driving the movable plate 12 of the first sliding table cylinder to move forward, thereby driving the first stop post 139 on the first positioning block 138 locked thereto to perform positioning and clamping. By utilizing the first oil buffer 134 installed on the first limit block 133 to play a certain buffering role, mainly to prevent the speed from being too fast during clamping, causing the first stop post 139 to collide with the substrate 5, and playing a certain speed buffering role; when the first lifting component 13 needs to descend back to its original position, the first sliding table cylinder 11 moves backward, the first stop post 139 leaves the substrate 5 to release it, and then the first lifting component 13 descends back to the initial position.

[0085] Embodiment 2

[0086] As Figures 5 to 7 shown, this embodiment discloses a clamping and straightening structure. On the basis of Embodiment 1, the difference between this embodiment and Embodiment 1 is that the structure of the driving component is changed, and a second buffer component 24 is provided.

[0087] The following takes the clamping and straightening structure as the left and right positioning components 2 as an example to illustrate the present utility model.

[0088] The driving component of this embodiment includes a second cylinder 21. The second cylinder 21 is a two-way cylinder, and the two-way cylinder is a thin type air gripper. The two telescopic ends of the second cylinder 21 are respectively connected with a second lifting component 25 through telescopic blocks 22, and the second lifting component 25 is adapted to drive the clamping component and the first buffer component to lift.

[0089] In some embodiments, the second lifting component 25 includes a second limit block 253, a second lifting cylinder 257, a second lifting cylinder mounting plate 251, a second linear guide 255, a second guide block 256, and a second limit strengthening block 252.

[0090] The second limit reinforcing block 252, the second linear guide rail 255, and the second lifting cylinder 257 are locked to the second lifting cylinder mounting plate 251 by screws. The oil buffer is screwed into the screw hole of the second limit block 253 by rotation. Before the lifting assembly starts, rotate and twist the oil buffer to adjust the position for clamping and limiting, so as to make the clamping and positioning accuracy accurate. The accuracy range is adjustable. After the position is adjusted, it can be locked tightly with two nuts, and its position accuracy will not change due to external influences. The telescopic end of the second lifting cylinder 257 is connected to the second limit block 253 through the second floating joint 2510. The second floating joint 2510 is stuck in the U-shaped groove of the second positioning block 258. The second limit block 253 is locked to the second positioning block 258 by screws. The second lifting cylinder mounting plate 251 is connected to the side wall of the second lifting cylinder 257. The second linear guide rail 255 is arranged on the second lifting cylinder mounting plate 251. The second guide block 256 is connected to the second limit block 253 and is slidably assembled on the second linear guide rail 255. The second limit reinforcing block 252 is connected to the second lifting cylinder mounting plate 251 and limits the lifting position of the second lifting cylinder 257.

[0091] When the second lifting assembly 25 starts, the second lifting cylinder 257 starts to move up and down. The second floating joint 2510 installed on the second lifting cylinder 257 drives the second positioning block 258 to move up and down, so as to realize the lifting function. The second linear guide rail 255 enhances the strength of the second lifting assembly 25 and will not shake during the up and down movement; when the second lifting assembly 25 completes the rising action, the thin air gripper starts to move forward, driving the telescopic block 22 to move forward, thereby driving the second stop post 259 on the second positioning block 258 locked to it to perform positioning and clamping. The second oil buffer 254 installed on the second limit block 253 plays a certain buffering role, mainly to prevent the speed from being too fast during clamping, so that the second stop post 259 collides with the substrate 5, playing a certain role in speed buffering; when the second lifting assembly 25 is to descend back to the original position, the thin air gripper moves backward, and the second stop post 259 leaves the substrate 5 to release it, and then the second lifting assembly 25 descends back to the initial position.

[0092] In some embodiments, at least one second buffer assembly 24 is arranged between the telescopic block 22 and the second lifting assembly 25. The second buffer assembly 24 plays a buffering role, that is, when clamping the substrate 5, the second buffer assembly 24 slows down the telescopic speed of the second cylinder 21.

[0093] The second buffer component 24 includes a linear bearing 245, a fixing block 246, a sliding rod 241, a first washer 242 and a second washer 243. The fixed end of the linear bearing 245 is connected to the telescopic block 22 through the fixing block 246. The side wall of the fixing block 246 is fixedly connected to the telescopic block 22. The linear bearing 245 is installed in cooperation with the blind pin hole on the telescopic block 22 and locked by screws. A through hole is formed in the fixing block 246. The sliding rod 241 is slidably assembled on the linear bearing 245. One end of the sliding rod 241 is connected to the second lifting cylinder mounting plate 251 of the second lifting component 25, and the other end of the sliding rod 241 extends out of the through hole of the fixing block 246. The first washer 242 is arranged on the side wall of the sliding rod 241 extending out of the fixing block 246. The outer diameter of the first washer 242 is larger than the outer diameter of the through hole. Thus, when the telescopic block 22 and the fixing block 246 move along the clamping direction, the first washer 242 will be driven to move along the clamping direction. The second washer 243 is fixedly arranged at the end of the sliding rod 241 extending out of the fixing block 246. A compression spring 244 is arranged between the second washer 243 and the first washer 242. Thus, when the first washer 242 moves, it will drive the compression spring 244 to squeeze the second washer 243, and then the second washer 243 will drive the sliding rod 241 to slide along the clamping direction.

[0094] In this embodiment, the thin air gripper is used to drive the telescopic block 22 to move left and right, so as to realize the left and right clamping and positioning function; the compression spring 244 is used to play a certain strength buffering role during left and right clamping. The clamping force during clamping is determined by the spring force to prevent the substrate 5 from being scratched or cracked.

[0095] Embodiment 3

[0096] As Figures 8 to 11 shown, a clamping and positioning device includes a positioning table 3, a carrier table 4 and the clamping and positioning structure in Embodiment 1 or Embodiment 2.

[0097] One or two clamping and positioning structures are provided. When one clamping and positioning structure is provided, the clamping and positioning structure is suitable for clamping the substrate 5 left and right or front and back; when two clamping and positioning structures are provided, one clamping and positioning structure is suitable for clamping the substrate 5 left and right, and the other clamping and positioning structure is suitable for clamping the substrate 5 front and back.

[0098] The carrier table 4 is arranged on the positioning table 3, and the substrate 5 is placed on the carrier table 4. A plurality of positioning grooves 42 adapted to the stop pins are formed in the carrier table 4. When the stop pins clamp the substrate 5, the telescopic end of the oil buffer will touch the positioning table 3. Thus, the oil buffer plays a buffering role. The stop pins pass through the positioning grooves 42 and move along the positioning grooves 42 towards the position of the substrate 5. When the stop pins contact the substrate 5, the clamping of the substrate 5 is realized.

[0099] A lifting mechanism 6 is arranged below the positioning table 3, and the lifting mechanism 6 is adapted to drive the substrate 5 to move up and down. The lifting mechanism 6 includes a lifting cylinder 61, a lifting plate, and ejector pins 62. The piston rod of the lifting cylinder 61 is connected to the lifting plate, and a plurality of ejector pins 62 are arranged on the lifting plate, and each ejector pin 62 can pass through the carrier table 4 respectively. When it is necessary to lift the substrate 5, the ejector pins 62 pass through the carrier table 4 under the drive of the lifting cylinder 61 and lift the substrate 5; when it is not necessary to lift the substrate 5, the ejector pins 62 retract from the carrier table 4 under the drive of the lifting cylinder 61.

[0100] The specific working process of the above clamping device is as follows:

[0101] Place the substrate 5 on the positioning table 3, and clamp the substrate 5 front and back through a plurality of first stoppers 139 on the front and back positioning assembly 1, and clamp the substrate 5 left and right through a plurality of second stoppers 259 on the left and right positioning assembly 2.
