Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to a laminating device for producing optical adhesive. Background Technology

[0002] OCA laminating machines, also known as vacuum laminating machines or touchscreen laminating machines, are industrial automation products controlled by PLCs or microcontrollers. They are used for laminating mobile phone screens. The lamination principle involves placing the mobile phone's LCD screen and glass cover in a vacuum chamber. The machine's cylinder pressure lowers the inner mold of the vacuum cylinder, completely pressing the glass cover and LCD screen, which are placed in the lower mold of the vacuum cylinder, together.

[0003] The prior art patent CN214669936U discloses a precision-positioning optical adhesive bonding device. During clamping, the telescopic frame can be moved by the cooperation between the positive and negative threaded rods and the threaded sleeve, thereby changing the distance between the two clamping blocks. This allows the device to clamp more components of various sizes. However, when clamping some square components, it can only clamp the two sides of the square component and cannot align it with the bonding plate. The operator needs to manually align it, which is cumbersome and has low practicality. To address the above problems, a bonding device for optical adhesive production is proposed.

[0006] The bonding mechanism includes a telescopic cylinder, which is fixedly installed on the top of the box. The output end of the telescopic cylinder extends into the box and is fixedly installed with an adhesive plate. A column is fixedly installed on the bottom inner wall of the box, and a support plate is fixedly installed on the top of the column.

[0007] The clamping and positioning mechanism includes four movable plates. The top of the support plate is provided with four T-shaped grooves, and a T-shaped slide plate is slidably installed in each of the four T-shaped grooves. The bottom of the four movable plates is fixedly connected to the top of the four T-shaped slide plates respectively. The four T-shaped slide plates are connected to each other through a linkage component. Clamping components are provided on the sides of the four movable plates.

[0008] Preferably, the linkage assembly includes four screw guide sleeves, and the housing has four transmission chambers. Each of the four transmission chambers has a rotating hole on its inner side wall. The four screw guide sleeves are rotatably installed in the four rotating holes. Each of the four screw guide sleeves has a screw threadedly installed inside it. The ends of the four screws are fixedly connected to the sides of the four T-shaped slides. The outer peripheral walls of two of the screw guide sleeves are provided with rotating units. Each pair of matching screw guide sleeves is connected to each other through a transmission assembly.

[0009] Preferably, the rotating unit includes a rotating gear, which is fixedly sleeved on the outer peripheral wall of the screw guide sleeve. A limiting shaft is fixedly installed on the relative inner walls of the transmission cavity. A lifting rack is slidably sleeved on the outer peripheral wall of the limiting shaft. The lifting rack is meshed with the rotating gear. The lifting rack is connected to the telescopic cylinder through a pressing element.

[0010] Preferably, the extrusion element includes a square iron block and an electromagnet. A lifting hole is provided on the inner side wall of the transmission cavity. The square iron block is slidably disposed in the lifting hole. One side of the square iron block is fixedly connected to the side of the lifting rack. A T-shaped fixing plate is fixedly sleeved on the outer peripheral wall of the output end of the telescopic cylinder. The electromagnet is fixedly disposed on the side of the T-shaped fixing plate. The electromagnet is adapted to the square iron block.

[0011] Preferably, the two transmission cavities of each phase are connected by an L-shaped cavity. A partition is fixedly installed on the opposite inner wall of the L-shaped cavity. A circular hole is opened on the side of the partition. A rotating shaft is rotatably installed in the circular hole. A sprocket is fixedly sleeved on the outer peripheral wall of one of the screw guide sleeves. A chain is meshed on both sprockets. A driving bevel gear is fixedly sleeved on the other end of the rotating shaft. A driven bevel gear is fixedly sleeved on the outer peripheral wall of the other screw guide sleeve. The driving bevel gear and the driven bevel gear are meshed together.

[0012] Preferably, the clamping assembly includes a sliding shaft, a sliding hole is provided on the side of the movable plate, the sliding shaft is slidably disposed in the sliding hole, a clamping plate is fixedly disposed at one end of the sliding shaft, a sensing unit is provided on the side of the clamping plate, a limiting circular plate is fixedly disposed at the other end of the sliding shaft, and a return spring is sleeved on the outer periphery of the sliding shaft.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, when the electromagnet is energized, it drives the square iron block to move downward synchronously through its attraction with the square iron block. Then, the square iron block drives the lifting rack to move synchronously, so that it meshes with the rotating gear. When the square element is clamped and fixed, the electromagnet is de-energized. At this time, its attraction with the square iron block disappears, so that the adhesive plate can continue to move downward.

[0016] 2. In this utility model, when one of the screw guide sleeves rotates, the meshing action of the two sprockets and the chain can drive the rotating shaft and the driving bevel gear to achieve rotation. Thus, through the meshing action of the remaining driven bevel gears, the other screw guide sleeve is driven to rotate synchronously, enabling multiple moving plates to move synchronously.

[0017] 3. In this utility model, when the moving plate moves horizontally, it can drive the sliding shaft and clamping plate to move synchronously, so that the clamping plate contacts the side of the square element. Through the synchronous movement of the four clamping plates, the square element can be aligned with the adhesive plate. When the four main travel switches and the four auxiliary travel switches are in contact, an electrical signal can be transmitted to the two electromagnets to de-energize them and release the adsorption connection with the square iron block, so as to avoid affecting the lifting and lowering movement of the adhesive plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Reference Figures 1-5 The optical adhesive production bonding equipment shown includes a box body 1 and a box door. The box body 1 and the box door are hinged together. A bonding mechanism is provided inside the box body 1 for performing adhesive bonding operations. A clamping and positioning mechanism is provided inside the box body 1 for fixing the components to be bonded.

[0027] The bonding mechanism includes a telescopic cylinder 2, which is fixedly installed on the top of the box 1. The output end of the telescopic cylinder 2 extends into the box 1 and is fixedly installed with an adhesive plate 3. A column 4 is fixedly installed on the bottom inner wall of the box 1, and a support plate 5 is fixedly installed on the top of the column 4.

[0028] The clamping and positioning mechanism includes four movable plates 6. The top of the support plate 5 is provided with four T-shaped slide grooves. T-shaped slide plates 7 are slidably installed in each of the four T-shaped slide grooves. The bottom of the four movable plates 6 is fixedly connected to the top of the four T-shaped slide plates 7 respectively. The four T-shaped slide plates 7 are connected to each other through a linkage component. Clamping components are provided on the sides of the four movable plates 6.

[0029] With the above structure, when in use, the square element is placed on the top of the support plate 5, and then the telescopic cylinder 2 is activated to drive the adhesive plate 3 to move downward. When the telescopic cylinder 2 moves downward, the linkage component drives the four T-shaped slide plates 7 and the four moving plates 6 to move synchronously in the direction of the axis. When the four moving plates 6 move, they drive the four clamping components to move synchronously, thereby achieving the function of aligning and clamping the square element.

[0030] like Figure 2 and Figure 3As shown, the linkage assembly includes four screw guide sleeves 8. The housing 1 has four transmission chambers, each with a rotating hole on its inner side wall. The four screw guide sleeves 8 are rotatably installed in the four rotating holes. Each screw guide sleeve 8 has a screw 21 threadedly installed inside it. The ends of the four screws 21 are fixedly connected to the sides of four T-shaped sliding plates 7. Rotation of the screw guide sleeves 8 enables the screws 21 to move horizontally under the action of the threads, thereby driving the T-shaped sliding plates 7 to move synchronously. Two of the screw guide sleeves 8 have rotating units on their outer periphery, each adapted to... The two screw guide sleeves 8 are connected by a transmission assembly. The rotating unit includes a rotating gear 9, which is fixedly sleeved on the outer circumferential wall of the screw guide sleeve 8. The inner walls of the transmission cavity are fixedly installed with a limit shaft 11. A lifting rack 10 is slidably sleeved on the outer circumferential wall of the limit shaft 11. The lifting rack 10 is meshed with the rotating gear 9. With this configuration, the lifting rack 10 can drive the rotating gear 9 to rotate, thereby making the screw guide sleeve 8 rotate. The lifting rack 10 is connected to the telescopic cylinder 2 through a pressing element.

[0031] Specifically, when the screw guide sleeve 8 rotates, the screw 21 and the T-shaped slide plate 7 can move horizontally through the thread action. Thus, through the connection between the T-shaped slide plate 7 and the moving plate 6, the moving plate 6 can be driven to achieve synchronous movement. When the lifting rack 10 moves downward, it can drive the rotating gear 9 to rotate through its meshing with the rotating gear 9, thereby driving the screw guide sleeve 8 to achieve rotation.

[0032] like Figure 1 As shown, the extrusion element includes a square iron block 12 and an electromagnet 14. A lifting hole is provided on the inner wall of the side of the transmission cavity. The square iron block 12 is slidably disposed in the lifting hole. One side of the square iron block 12 is fixedly connected to the side of the lifting rack 10. A T-shaped fixing plate 13 is fixedly sleeved on the outer wall of the output end of the telescopic cylinder 2. The electromagnet 14 is fixedly disposed on the side of the T-shaped fixing plate 13. Through the setting of the electromagnet 14, it can attract the square iron block 12 when energized, thereby driving the square iron block 12 to achieve synchronous movement. The electromagnet 14 is compatible with the square iron block 12.

[0033] Specifically, when the electromagnet 14 is energized, it attracts the square iron block 12, causing the square iron block 12 to move downward synchronously. In turn, the square iron block 12 drives the lifting rack 10 to move synchronously, so that it meshes with the rotating gear 9. After the square element is clamped and fixed, the electromagnet 14 is de-energized, and the attraction between it and the square iron block 12 disappears, so that the adhesive plate 3 can continue to move downward.

[0034] like Figure 3 , Figure 4 and Figure 5As shown, the two transmission chambers of each phase are connected by an L-shaped cavity. A partition 15 is fixedly installed on the inner wall of the L-shaped cavity. A circular hole is opened on the side of the partition 15, and a rotating shaft 16 is rotatably installed in the circular hole. A sprocket 17 is fixedly sleeved on the outer wall of one of the screw guide sleeves 8. A chain 18 is meshed on both sprockets 17. A driving bevel gear 19 is fixedly sleeved on the other end of the rotating shaft 16, and a driven bevel gear 20 is fixedly sleeved on the outer wall of the other screw guide sleeve 8. This arrangement enables the other screw guide sleeve 8 to rotate synchronously when one of the screw guide sleeves 8 rotates. The driving bevel gear 19 and the driven bevel gear 20 are meshed together.

[0035] Specifically, when one of the screw guide sleeves 8 rotates, the meshing of the two sprockets 17 and the chain 18 drives the rotating shaft 16 and the driving bevel gear 19 to rotate. Thus, through the meshing of the remaining driven bevel gears 20, the other screw guide sleeve 8 is driven to rotate synchronously, enabling the multiple moving plates 6 to move synchronously.

[0036] like Figure 3 As shown, the clamping assembly includes a sliding shaft 22. A sliding hole is provided on the side of the moving plate 6. The sliding shaft 22 is slidably disposed in the sliding hole. A clamping plate 23 is fixedly disposed at one end of the sliding shaft 22. Through the setting of the clamping plate 23, the moving plate 6 can drive the clamping plate 23 to move synchronously when moving horizontally, thereby clamping the four sides of the square element. A sensing unit is provided on the side of the clamping plate 23. A limit circular plate 26 is fixedly disposed at the other end of the sliding shaft 22. A return spring 27 is sleeved on the outer wall of the periphery of the sliding shaft 22. The sensing unit includes a main travel switch 24 and a secondary travel switch 25. Sensing grooves are provided on the opposite sides of the clamping plate 23 and the moving plate 6. The main travel switch 24 and the secondary travel switch 25 are respectively disposed in the two sensing grooves. The main travel switch 24 and the secondary travel switch 25 are both electrically connected to the electromagnet 14.

[0037] Specifically, when the moving plate 6 moves horizontally, it can drive the sliding shaft 22 and the clamping plate 23 to move synchronously, so that the clamping plate 23 contacts the side of the square element. Through the synchronous movement of the four clamping plates 23, the square element can be aligned with the adhesive plate 3. When the four main travel switches 24 and the four auxiliary travel switches 25 are in contact, an electrical signal can be transmitted to the two electromagnets 14 to de-energize them and release the adsorption connection with the square iron block 12, so as to avoid affecting the lifting and lowering movement of the adhesive plate 3.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
