Description

Technical Field

[0001] This utility model relates to the field of adsorption and transfer device technology, and in particular to an adjustable vacuum adsorption device and a substrate transfer device. Background Technology

[0002] In the production and quality inspection of mobile phone displays, in order to ensure the smooth progress of each step, it is usually necessary to use specialized transfer equipment to efficiently and safely transfer glass substrates or partially completed displays between different processes.

[0003] In traditional substrate transfer devices, the position of the suction cup components is difficult to adjust, making it difficult to adapt to workpieces of different sizes. This reduces the equipment's adaptability. When transferring workpieces, some suction cup components may fail due to unforeseen circumstances, causing offset when clamping the workpiece. This can easily lead to the workpiece tilting or slipping, resulting in damage and affecting the overall stability of the equipment. Furthermore, because some workpieces have non-standard dimensions, some suction cup components may have difficulty clamping them accurately, increasing downtime and affecting the efficiency of subsequent workpiece transfer. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low equipment compatibility and easy tilting of workpieces in the prior art, and to propose an adjustable vacuum adsorption device and a substrate transfer device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable vacuum adsorption device and substrate transfer device includes a worktable, in which multiple suction cups are symmetrically arranged. Three pairs of slide rods are linearly arranged inside the worktable. Two slide grooves are symmetrically opened at the ends of the worktable. Multiple first moving blocks are respectively provided on the outer walls of the slide grooves and slide rods. Each first moving block is provided with an adjustment component for adjusting the suction cups. A protective plate is provided on the side wall of the first moving block. Two second fixed seats are symmetrically arranged on the side wall of the worktable. A servo motor is provided on the side wall of the second fixed seat. A transmission component is provided at the output end of the servo motor.

[0007] Preferably, the adjustment assembly includes a second moving block and a rotating bolt. A sliding groove is provided in the first moving block. The second moving block is disposed on the inner sidewall of the sliding groove, and the end of the second moving block is connected to the end of the suction cup. The rotating bolt is inserted into the end of the first moving block, and the end of the rotating bolt is connected to the sidewall of the second moving block.

[0008] Preferably, the first movable block has two symmetrically formed grooves on its side wall, and a third movable block is provided in the groove. The end of the third movable block is connected to the side wall of the protective plate, and a return spring is also provided in the groove.

[0009] Preferably, the transmission assembly includes a bidirectional lead screw and a connecting block. The bidirectional lead screw is disposed on the side wall of the second fixed seat, and the end of the bidirectional lead screw is coaxially connected to the output end of the servo motor. The connecting block is disposed on the outer side wall of the bidirectional lead screw, and the end of the connecting block is connected to the bottom of the first moving block.

[0010] Preferably, the workbench sidewall is symmetrically provided with four first fixed seats, each first fixed seat having a guide rod at its end, and a limit block is coaxially provided at the center of the guide rod.

[0011] Preferably, the workbench sidewall is provided with a plurality of limiting holes symmetrically, and a limiting rod is coaxially provided in the limiting holes.

[0012] Preferably, it includes a transfer device for moving the adjustable vacuum adsorption device.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model, by setting an adjustment component, drives the second moving block to move in the sliding groove by rotating the bolt, thereby driving the suction cup to make precise position adjustment, ensuring that the suction cup can closely fit the workpiece surface, improving the stability and accuracy during clamping.

[0015] 2. This utility model uses a protective plate and a return spring to compress the connecting rod, causing the connecting rod to move the protective plate. This allows the inner wall of the protective plate to abut against the outer wall of the workpiece, reducing the tilting and slippage of the workpiece during transport due to unexpected situations and ensuring the overall stability of the equipment during operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 An adjustable vacuum adsorption device and a substrate transfer device are included, comprising a transfer device for moving the adjustable vacuum adsorption device, and a worktable 1. Multiple suction cups 12 are symmetrically arranged inside the worktable 1. Three pairs of slide rods 8 are symmetrically fixed on the inner sidewall of the worktable 1. Two slide grooves 3 are symmetrically opened at the end of the worktable 1. Multiple first moving blocks 11 are respectively provided on the outer sidewall of the slide grooves 3 and the slide rods 8. Through the cooperation of the slide rods 8 and the slide grooves 3, the multiple suction cups 12 slide on the outer sidewall of the slide rods 8 and the slide grooves 3 via the first moving blocks 11, which facilitates the operator to adjust the multiple suction cups 12 and improves the overall adaptability of the equipment.

[0024] like Figure 4 As shown, the first moving block 11 is equipped with an adjustment component for adjusting the suction cup 12. The adjustment component includes a second moving block 16 and a rotating bolt 17. The first moving block 11 has a sliding groove, and the second moving block 16 is slidably disposed on the inner side wall of the sliding groove. The end of the second moving block 16 is fixedly connected to the bottom of the suction cup 12. The rotating bolt 17 is inserted into the end of the first moving block 11. The end of the first moving block 11 has a threaded hole that matches the rotating bolt 17. The external thread of the rotating bolt 17 is engaged with the internal thread of the first moving block 11. The end of the rotating bolt 17 is rotatably connected to the side wall of the second moving block 16. Through the mutual cooperation of the rotating bolt 17 and the second moving block 16, it is convenient for the operator to adjust the position of the suction cup 12, preventing secondary adjustment of the workpiece due to different workpiece sizes, improving the workpiece's secondary adjustment effect, and ensuring the suction cup 12's fixation effect on the workpiece.

[0025] like Figure 5As shown, the first moving block 11 has two symmetrical grooves on its side wall. The slider of the third moving block 18 is disposed on the inner side wall of the groove. The end of the third moving block 18 is fixedly connected to the side wall of the protective plate 14. The end of the return spring 19 is fixedly disposed on the inner side wall of the groove, and the other end of the return spring 19 is fixedly disposed on the end of the third moving block 18. Through the cooperation of the third moving block 18 and the return spring 19, the workpiece is prevented from falling off due to accidental circumstances. The inner side wall of the protective plate 14 protects the outer side wall of the workpiece, ensuring the stability of the workpiece during processing.

[0026] The first moving block 11 has a protective plate 14 on its side wall, and the inner side wall of the protective plate 14 has a rubber pad. Two second fixed seats 5 are symmetrically fixed on the side wall of the worktable 1. The servo motor 6 is fixed on the side wall of the second fixed seat 5. A shock-absorbing pad is provided between the servo motor 6 and the second fixed seat 5. A servo controller is provided on the servo motor 6. Through the operation program of the servo controller, the rotation direction and rotation angle of the output end of the servo motor 6 are adjusted so as to effectively control the direction of rotation and provide driving force for the bidirectional lead screw 7. This operation program is existing technology and will not be described in detail here.

[0027] like Figure 3 As shown, the output end of the servo motor 6 is equipped with a transmission assembly, which includes a bidirectional lead screw 7 and a connecting block 10. The bidirectional lead screw 7 is rotatably mounted on the side wall of the second fixed base 5, and the end of the bidirectional lead screw 7 is coaxially and fixedly connected to the output end of the servo motor 6. The connecting block 10 is located on the outer side wall of the bidirectional lead screw 7, and a threaded hole adapted to the bidirectional lead screw 7 is opened in the connecting block 10. The end of the connecting block 10 is connected to the bottom of multiple first moving blocks 11. Through the mutual cooperation of the connecting block 10 and the bidirectional lead screw 7, it is convenient for the operator to adjust the position of multiple suction cups 12, improve the adaptability of the equipment to workpieces of different sizes, and ensure the working efficiency of the overall equipment during operation.

[0028] Four first fixed seats 4 are symmetrically fixedly installed on the side wall of the workbench 1. The guide rod 13 is fixedly installed at the end of the first fixed seat 4. The limiting block 9 is coaxially fixedly installed at the center of the guide rod 13. Through the cooperation of the limiting block 9 and the guide rod 13, the offset of the connecting block 10 when it moves is reduced. The limiting block 9 also prevents multiple suction cups 12 on both sides from colliding, which could cause malfunctions during equipment operation and affect the fixing effect of subsequent equipment operation.

[0029] Multiple limiting holes 15 are symmetrically opened on the side wall of the workbench 1. A limiting rod 2 is coaxially arranged in the limiting hole 15. Through the cooperation of the limiting hole 15 and the limiting rod 2, the operator can easily limit and fix the first moving block 11, reducing the possibility of the workpiece accidentally falling off.

[0030] The functional principle of this utility model can be explained through the following operation methods:

[0031] The operator starts the servo motor 6, and the output of the servo motor 6 drives the bidirectional lead screw 7 to rotate. The two connecting plates 10 move on the outer wall of the bidirectional lead screw 7 through the threaded holes. The two connecting plates 10 slide on the outer wall of the guide rods 13 on both sides. The connecting plates 10 drive multiple first moving blocks 11 to move on multiple slide rods 8. The operator places the workpiece at the end of the worktable 1 and starts the suction cup 12 to adsorb and fix the workpiece. The operator moves the first blocks 11 on both sides to slide in the slide groove 3. The limit rod 2 is inserted to limit the first limit rod 11 and reduce the excessive sliding of the first moving block 11.

[0032] Since some workpieces have different sizes and specifications, the second moving block 16 is driven to slide in the sliding groove by rotating the bolt 17, which makes it convenient for the operator to adjust the position of the suction cup 12. The return spring 19 squeezes the end of the connecting rod 18, causing the connecting rod 18 to move the protective plate 14, so that the inner side wall of the protective plate 14 and the outer side wall of the workpiece abut against each other, preventing the workpiece from falling off due to accidental situations.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
