Description

Technical Field

[0001] This utility model relates to the field of display panel manufacturing equipment technology, and in particular to a POL bonding machine with an intelligent alignment mechanism. Background Technology

[0002] Polarizing film, abbreviated as POL, is a key component in the display panel manufacturing industry. The performance of the POL bonding machine directly impacts product quality and production efficiency. In recent years, with the rapid development of display technology, higher demands have been placed on the precision, efficiency, and adaptability of POL bonding machines, highlighting the shortcomings of existing equipment.

[0003] Traditional POL (Polymer Optical Loading) machines are poorly adaptable to display panels and polarizers of varying sizes and shapes. In today's market, display products are increasingly diverse in size and shape, ranging from a few inches for smartwatch screens to tens of inches for television panels. Traditional loading machines are often designed for specific sizes and shapes. When switching to produce different specifications, significant time and manpower are required for adjusting the mechanical structure and setting parameters. Some machines are even incompatible with certain special-shaped products, severely limiting production flexibility and efficiency. They cannot quickly respond to market changes and diverse customer needs, resulting in limited applicability and inconvenience. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a POL bonding machine with an intelligent alignment mechanism.

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

[0006] A POL bonding machine with an intelligent alignment mechanism includes a support base, a worktable, and support frames. The worktable is fixed to the upper surface of the support base. Support frames are fixed to the left and right sides of the rear end of the upper surface of the worktable. Hydraulic cylinders are vertically fixed to the top front end of each support frame. Mounting plates are fixed to the bottom of the push rods at the power output ends of the hydraulic cylinders. Electric suction cups are fixed to the front and rear ends of the bottom of the mounting plates. A top connecting plate is sleeved on the end of the mounting plate away from the middle of the support base. Top connecting members are sleeved on the front and rear ends of the outer wall of the top connecting plate. The top connecting member is located near the middle of the support base. Each end is fixed with a top limiting plate. Electric push rods are horizontally fixed at the left and right ends of the upper surface of the worktable. One end of the push rod of each of the two electric push rods is fixedly connected to a bottom connecting plate. A servo motor is fixed at the front end of each bottom connecting plate. A two-way lead screw is rotatably connected to the rear end of the transmission shaft of each servo motor. Bottom connecting pieces are sleeved on the front and rear ends of the outer side of the bottom connecting plate. A bottom limiting plate is fixed at the end of each bottom connecting piece near the middle of the support base. A pressure sensor is fixed inside the lower part of each bottom limiting plate. An extension plate is fixedly connected to the top of each bottom limiting plate.

[0007] Preferably, the bottom of the top limiting plate is on the same horizontal plane, and the top of the bottom limiting plate is on the same horizontal plane.

[0008] Preferably, the outer wall of the top connecting plate is tightly attached to the inner wall of the top connecting member, and the outer wall of the bottom connecting plate is tightly attached to the inner wall of the bottom connecting member. The bottom connecting member and the top connecting member slide back and forth in the horizontal direction on the outer walls of the bottom connecting plate and the top connecting plate, respectively.

[0009] Preferably, the two bottom connectors are nested at the front and rear ends of the outer wall of the bidirectional lead screw, and the outer wall of the bidirectional lead screw and the inner wall of the bottom connector are connected by threads.

[0010] Preferably, the cross-sections of the bottom limiting plate and the top limiting plate are both arranged in the shape of the letter "L", and the middle parts of the bottom limiting plate and the top limiting plate are both located on the same vertical axis.

[0011] Preferably, the outer wall of the extension plate is in close contact with the inner wall of the top limiting plate, and the top limiting plate moves up and down vertically on the outer side of the extension plate.

[0012] After the substrate is placed on the surface of the worktable, two electric push rods simultaneously push the bottom connecting plate towards the center of the worktable. This causes the bottom connecting plate, along with the bottom limiting plate, extension plate, and top limiting plate, to move simultaneously. After the bottom limiting plate is in close contact with the left and right ends of the substrate, the pressure sensor sends a signal to the control panel to stop the hydraulic cylinder. At the same time, the servo motor drives the bidirectional lead screw to rotate in the bottom connector, causing the bottom connector to move the bottom limiting plate, extension plate, and top limiting plate towards the center of the bottom connecting plate. After the bottom limiting plate is in close contact with the front and rear ends of the substrate, the pressure sensor sends a signal to the control panel to stop the servo motor. This ensures that the four bottom limiting plates are in close contact with the four corners of the substrate, and the four top limiting plates are in close contact with the four corners of the polarizer. This enables rapid and intelligent alignment of the substrate and polarizer, resulting in higher accuracy for subsequent polarizer attachment. It also expands the applicability of the device and makes it more convenient to use. Attached Figure Description

Detailed Implementation

[0019] Example 1, referring to Figure 1-4A POL bonding machine with an intelligent alignment mechanism includes a support base 1, a worktable 2, and a support frame 201. The worktable 2 is fixed to the upper surface of the support base 1, and the support frame 201 is fixed to both the left and right sides of the rear end of the upper surface of the worktable 2. The support frame 201 is characterized in that a hydraulic cylinder 202 is vertically fixed to the top front end of each support frame 201, and a mounting plate 203 is fixed to the bottom of the push rod at the power output end of the hydraulic cylinder 202. An electric suction cup 204 is fixed to the front and rear ends of the bottom of the mounting plate 203. A top connecting plate 205 is sleeved on the end of the mounting plate 203 away from the middle of the support base 1. Top connecting parts 206 are sleeved on the front and rear ends of the outer wall of the top connecting plate 205, and the top connecting parts 206 are close to the support base 1. One end of the middle section is fixed with a top limit plate 207. The left and right ends of the upper surface of the worktable 2 are horizontally fixed with electric push rods 3. The push rod ends of the power output ends of the two electric push rods 3 are fixedly connected to a bottom connecting plate 301. The front end of the bottom connecting plate 301 is fixed with a servo motor 302. The rear end of the transmission shaft of the power output end of the servo motor 302 is rotatably connected with a two-way lead screw 303. The front and rear ends of the outer side of the bottom connecting plate 301 are sleeved with bottom connecting parts 304. The bottom limit plate 305 is fixed at one end of the bottom connecting part 304 near the middle of the support base 1. The pressure sensor 306 is fixed inside the lower part of the bottom limit plate 305. The top of the bottom limit plate 305 is fixedly connected with an extension plate 307.

[0020] The bottom of the top limiting plate 207 is on the same horizontal plane, and the top of the bottom limiting plate 305 is on the same horizontal plane.

[0021] The outer wall of the top connecting plate 205 is in close contact with the inner wall of the top connecting piece 206, and the outer wall of the bottom connecting plate 301 is in close contact with the inner wall of the bottom connecting piece 304. The bottom connecting piece 304 and the top connecting piece 206 slide back and forth horizontally on the outer walls of the bottom connecting plate 301 and the top connecting plate 205, respectively.

[0022] After the substrate is placed on the upper surface of the worktable 2, the two electric push rods 3 simultaneously push the bottom connecting plate 301 toward the middle of the worktable 2, so that the bottom connecting plate 301 drives the bottom limiting plate 305, the extension plate 307 and the top limiting plate 207 to move simultaneously and closely adhere to the left and right ends of the substrate.

[0023] Two bottom connectors 304 are respectively nested at the front and rear ends of the outer wall of the bidirectional lead screw 303, and the outer wall of the bidirectional lead screw 303 and the inner wall of the bottom connector 304 are connected by threads.

[0024] The cross-sections of the bottom limiting plate 305 and the top limiting plate 207 are both arranged in the shape of the letter "L", and the middle parts of the bottom limiting plate 305 and the top limiting plate 207 are both on the same vertical axis.

[0025] To achieve intelligent alignment, this equipment is equipped with an integrated PLC controller that is electrically connected to the electric push rod 3 and the pressure sensor 306 respectively. It receives the signal from the pressure sensor 306 (detection accuracy ±0.1N) and then automatically controls the electric push rod 3 and the servo motor 302 to achieve an alignment error ≤ ±0.01mm and a response time ≤ 0.5s.

[0026] When the bottom limiting plate 305 is in close contact with the left and right ends of the substrate, the pressure sensor 306 sends a signal to the control panel to stop the hydraulic cylinder 202. At this time, the servo motor 302 drives the bidirectional lead screw 303 to rotate in the bottom connector 304, so that the bottom connector 304 drives the bottom limiting plate 305, the extension plate 307 and the top limiting plate 207 to move towards the middle of the bottom connecting plate 301 at the same time. After the bottom limiting plate is in close contact with the front and rear ends of the substrate, the pressure sensor 306 sends a signal to the control panel to stop the servo motor 302. This allows the four bottom limiting plates 305 to be in close contact with the four corners of the substrate at the same time, and the four top limiting plates 207 to be in close contact with the four corners of the polarizer at the same time. This enables a fast and intelligent alignment operation of the substrate and the polarizer, resulting in higher subsequent polarizer attachment accuracy. It also improves the applicability of the device and makes it more convenient to use.

[0027] Example 2 differs from Example 1 in that, in this example, the outer wall of the extension plate 307 is closely attached to the inner wall of the top limiting plate 207, and the top limiting plate 207 moves up and down vertically on the outer side of the extension plate 307.

[0028] During the attachment process, the hydraulic cylinder 202 pushes the polarizer adsorbed below the mounting plate 203 and the electric suction cup 204 to move downward. At this time, the top limiting plate 207 moves downward outside the extension plate 307 to limit the up and down movement of the top limiting plate 207, preventing misalignment and displacement during the up and down movement of the top limiting plate 207, and further improving the attachment accuracy of the polarizer limited by the top limiting plate 207.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
