Description

Technical Field

[0001] This utility model relates to the technical field of display panel bonding process equipment, and more specifically, to a flip-type vacuum PAD bonding mechanism. Background Technology

[0002] Most common lamination equipment on the market uses roller lamination, but for some special products, roller lamination is impossible, such as some 3D products and hard-to-hard products.

Furthermore, lamination is performed in a vacuum environment, greatly reducing the formation of lamination bubbles. It is thanks to this technology that the variety of electronic products used in our lives is so vast, and their appearances are more in line with popular preferences. However, existing vacuum lamination equipment has drawbacks such as cumbersome logistics and inconvenient fixture replacement and adjustment, thus requiring improvement. Utility Model Content

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] This embodiment provides a flip-type vacuum PAD bonding mechanism, which includes an upper cavity mechanism and a lower cavity mechanism located below the upper cavity mechanism;

[0037] like Figure 1 , 2 As shown, the upper cavity mechanism includes a flipping motor 13, a drive-side assembly 15, a support-side assembly 14, a crossbeam 11, an upper cavity assembly 16, an upper cavity extension cylinder 17, an upper fixture mounting plate 18, and an upper cavity gripper cylinder 19.

[0038] The drive-side assembly 15 and the support-side assembly 14 are respectively vertically disposed at both ends of the crossbeam 11.

[0039] The tilting motor 13 is mounted on the drive-side assembly 15. One end of the crossbeam 11 is connected to the tilting motor 13 via an L-shaped connecting plate 12, and the other end of the crossbeam 11 is movably connected to the support-side assembly 14 via the L-shaped connecting plate 12. When it is necessary to change or adjust the fixture, or when loading or unloading products, the cavity is tilted with the fixture facing upwards for easy operation.

[0040] The top of the upper cavity assembly 16 is connected to the crossbeam 11 via a connecting post.

[0041] The upper cavity extension cylinder 17 is installed in the middle of the crossbeam 11. The piston rod of the upper cavity extension cylinder 17 extends into the interior of the upper cavity assembly 16 and is connected to the upper fixture mounting plate 18. The upper fixture mounting plate 18 is connected to the upper fixture.

[0042] The fixture mounting plate is provided with upper cavity gripper cylinders 19 on both sides, and upper cavity grippers are installed on the upper cavity gripper cylinders 19.

[0043] A pressure sensor 110 is provided on one side of the upper fixture mounting plate 18 to detect the pressure that the product bears when it is attached.

[0044] The corresponding upper fixture is installed on the upper fixture mounting plate 18. A vacuum environment is created through an external air pipe to complete the adsorption and transfer of the product. At the same time, the upper cavity gripper cylinder 19 is equipped with a product clamping component to fix the product for a second time, preventing the product from shifting during vacuuming. After the product is placed, the upper cavity assembly 16 is rotated 180° by the flipping motor 13 so that the product faces down.

[0045] like Figure 3 As shown, the lower cavity mechanism includes a base plate 21, a middle plate 22, a mounting plate 23, a top plate 24, four vertical guide shafts 25, a Z-axis adjustment assembly, an adjustment assembly, a product fixing mechanism, and a lower fixture bearing mechanism.

[0046] The base plate 21, the intermediate plate 22, the mounting plate 23, and the top plate 24 are arranged sequentially along the Z-axis. One end of each vertical guide shaft 25 is connected to 21, and the other end passes through the intermediate plate 22 and the mounting plate 23 to connect to the top plate 24.

[0047] The Z-axis adjustment assembly includes a Z-axis motor 26, a Z-axis reducer 27, a Z-axis coupling 28, and a first ball screw 29 connected in sequence; one end of the first ball screw 29 passes through the Z-axis coupling 28, and the other end passes through the intermediate plate 22 and the mounting plate 23.

[0048] The adjustment assembly includes a UVW platform 41 fixed to the upper side of the mounting plate 23. The four corners of the top of the UVW platform 41 are connected to one end of the fixing column 43 via mounting bases 42. The other end of the fixing column passes through the lower cavity and connects to the product fixing mechanism. The product fixing mechanism is connected to the UVW platform 41 to realize the actual alignment function of the membrane material.

[0049] like Figure 4 As shown, the product fixing mechanism includes a gripper base plate 51, a left gripper mechanism, a right gripper mechanism, and two Y-axis adjustment mechanisms. The left gripper mechanism and the right gripper mechanism are symmetrically arranged.

[0050] Linear guide rails 52 are respectively provided on both sides of the gripper base plate 51. Both the left and right gripper mechanisms include a fixed gripper 53, a movable gripper 57, a forward / reverse cylinder 54, a cylinder mounting plate 55, a lifting cylinder 56, and gripper linear guide rails. The two sides of the fixed gripper 53 are slidably connected to the corresponding linear guide rails 51. The forward / reverse cylinder 54 and gripper linear guide rails are mounted on the lower side of the fixed gripper 53, and are arranged parallel to each other. One end of the cylinder mounting plate 55 is connected to the piston rod of the forward / reverse cylinder 54, and the other end is slidably connected to the gripper linear guide rail. The lifting cylinder 56 is mounted on the cylinder mounting plate 55, and the movable gripper 57 is mounted on the lifting cylinder 56. The clamping of the membrane material is controlled by the lifting cylinder 56 and the forward / reverse cylinder 54.

[0051] Two Y-axis adjustment mechanisms are symmetrically arranged on both sides of the gripper base plate 51. Each Y-axis adjustment mechanism includes a Y-axis motor 581, a fixed plate 582, a connecting plate 583, and a third ball screw 584. The Y-axis motor 581 is connected to the gripper base plate 51 via a mounting base, the fixed plate 582 is connected to the gripper base plate 51, and the connecting plate 583 is connected to the fixed gripper 53. The Y-axis motor 581 is connected to the third ball screw 584 via a Y-axis coupling, and the third ball screw 584 passes through the fixed plate 582 and is connected to the connecting plate 583. The Y-axis adjustment mechanism can adjust the distance between the left and right gripper mechanisms, accommodating different size requirements.

[0052] like Figure 5 As shown, the lower fixture support mechanism includes a servo motor 31, a reducer 32, a second ball screw 34, a flange seat 35, a PAD mounting plate, and a PAD fixture 36. The servo motor 31 is connected to the reducer 32, and the reducer 32 is connected to the second ball screw 34 through a coupling 33. The second ball screw 34 passes through the middle of the base plate 21 and the middle of the intermediate plate 22 and is connected to one end of the flange seat 35. The other end of the flange seat 35 passes through the lower cavity and is connected to the lower fixture mounting plate. The top of the lower fixture mounting plate is connected to the PAD fixture 36.

[0053] Membrane material fixing: The upper surface of PAD fixture 36 is on the same horizontal plane as the lower surface of the right gripper mechanism and the left gripper mechanism. The carrier membrane with the membrane material is placed on PAD fixture 36. By controlling the forward and backward cylinder 54 and the lifting cylinder 56, the lifting and backward movement of the right gripper mechanism and the left gripper mechanism can be realized to fix the membrane material.

[0054] Product alignment and calibration: The CCD first takes a picture of the product in the lower cavity assembly 61, then moves the lower cavity assembly 61 below the upper cavity assembly 16, and then takes a picture of the upper product. After the picture is taken, the UVW platform 41 drives the entire film clamping mechanism to perform visual calibration to ensure the product's bonding accuracy.

[0055] Cavity Closing Action: After the lower cavity reaches directly below the upper cavity, the upper cavity extension cylinder 17 closes the upper and lower cavities. Simultaneously, the Z-axis adjustment component pulls the membrane material down for contouring. After cavity closure, a vacuum is applied to the cavity. When the vacuum value reaches the set value, the Z-axis adjustment component and PAD fixture 36 rise simultaneously. When the membrane material just makes contact with the product on the upper cavity assembly 16, the upper cavity gripper cylinder 19 actuates, and the upper cavity gripper retracts. Then, the Z-axis adjustment component and PAD fixture 36 continue to rise. At this time, the pressure sensor outputs a pressure value. After the pressure value reaches the set value, the PAD fixture 36 stops rising and holds for 5 seconds. Pressure Holding Acceptance: The cavity is depressurized. When the pressure value inside the cavity is normal, the upper cavity extension cylinder 17 opens the cavity. Simultaneously, the Z-axis adjustment component and PAD fixture 36 return to the standby position, and the UVW platform 41 returns to the standby position. Then the internal mechanism of the lower cavity remains stationary, the lower cavity mechanism returns to the standby position, the right gripper mechanism and the left gripper mechanism return to their original states (reverse and upward states) to complete the unloading, and at the same time the upper cavity rotates 180° to return to the standby position.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
