Specifically, it is to laminate the diffusion film, lower light enhancement film, upper light enhancement film, shading film and other films on the semi-finished products composed of the frame and the light guide plate. The film is rectangular. The traditional backlight laminating machine uses a turntable mechanism to synchronously transfer the semi-finished products of multiple stations. Each station must be equipped with a positioning device and a film laminating device to perform the positioning and film laminating operations in sequence. This method is only suitable for the film laminating operation of small-sized (less than 7 inches) backlight products.

Exemplarily, each placement position 401 is used to place a type of film; the film transfer device 300 transfers the film from the placement position 401 to the corresponding film alignment device 100 for precise positioning, and then transfers the precisely positioned film to the semi-finished product on the corresponding workstation 251 to achieve film pasting of the semi-finished product; the semi-finished product to be pasted is placed on the loading position 253 of the support table 250 manually or mechanically, and the semi-finished products at different positions are transferred on the support table 250 along the Y-axis direction by the transfer and lifting device, the semi-finished product at the loading position 253 is transferred to the adjacent workstation 251, the semi-finished product at one workstation 251 is transferred to another adjacent workstation 251, and the semi-finished products are transferred in sequence at each workstation 251; different films are pasted on the semi-finished products at different workstations 251 of the support table 250; finally, the semi-finished product with the film pasted is transferred to the unloading position 254, and the semi-finished product at the unloading position 254 is transferred away manually or mechanically, so that the semi-finished product is pasted with multiple films.

[0056] In addition, the number of placement positions 401, the number of film alignment devices 100 and the number of workstations 251 are all set to one. This solution is suitable for attaching a film to a semi-finished product, and the specific process is similar and will not be repeated.

[0057] In another embodiment of the present application, please refer to Figures 3 to 5The diaphragm alignment device 100 includes: a first driving component 110, a connecting platform 120, a second driving component 130, a movable positioning member 140 and a fixed positioning member 150. The connecting platform 120 is driven by the first driving component 110 to move linearly. The second driving component 130 is arranged on the connecting platform 120, the axis of the first driving component 110 and the axis of the second driving component 130 are parallel to each other, and a guide block 130a is arranged at the output end of the second driving component 130. The movable positioning member 140 has a supporting surface 140a and two mutually perpendicular first positioning surfaces 140c. The movable positioning member 140 is slidably assembled on the connecting platform 120, and the sliding direction of the connecting platform 120 is perpendicular to the sliding direction of the movable positioning member 140; the movable positioning member 140 has a guide groove 140b, and the extension direction of the guide groove 140b forms an acute angle with the sliding direction of the movable positioning member 140.

The sliding direction of the connecting platform 120 is perpendicular to the sliding direction of the movable positioning member 140, so that the connecting platform 120 can move in two perpendicular directions.

[0058] Combination Figure 3 , Figure 6 When the diaphragm 10 needs to be positioned, the diaphragm 10 is placed on the support surface 140a of the movable positioning member 140. The diaphragm 10 initially placed on the support surface 140a of the movable positioning member 140 has a position deviation within a certain range in two vertical directions on the horizontal plane. The first drive component 110 and the second drive component 130 output a certain displacement, driving the movable positioning member 140 to move a predetermined displacement in two perpendicular directions, so that the movable positioning member 140 gradually approaches the fixed positioning member 150, so that the two first positioning surfaces 140c and the two second positioning surfaces 150a are respectively disposed on the four sides of the diaphragm 10, and the precise positioning of the diaphragm 10 can be achieved. The diaphragm alignment device has fewer parts, a simple and compact structure, and a low cost of use.

[0059] The axis of the first drive assembly 110 and the axis of the second drive assembly 130 can extend in the X-axis direction at the same time, or extend in the Y-axis direction at the same time, and both methods can achieve precise positioning of the diaphragm. The extension direction of the guide groove 140b is the length direction of the guide groove 140b. The connecting platform 120 is plate-shaped, and the first drive assembly 110 and the second drive assembly 130 are respectively located on opposite sides of the connecting platform 120. In this way, the position in the up and down directions is fully utilized, making the overall structure compact.

[0060] In another embodiment of the present application, please refer to Figures 3 to 5A first linear guide mechanism 161 is provided between the connecting platform 120 and the base. The first linear guide is provided to facilitate the stable and reliable linear sliding of the connecting platform 120. Among them, the guide rail 161a can be installed on the base, the slider 161b is installed on the connecting platform 120, and the slider 161b is slidably assembled on the guide rail 161a. A second linear guide mechanism 162 is provided between the connecting platform 120 and the movable positioning member 140. The second linear guide is provided to facilitate the stable and reliable linear sliding of the movable positioning member 140.

[0061] In another embodiment of the present application, please refer to Figures 3 to 5 The diaphragm alignment device 100 further includes a first support body 1611 disposed on the base and used to support the first linear guide mechanism 161, and a second support body 1621 disposed on the connecting platform 120 and used to support the second linear guide mechanism 162. The first support body 1611 is provided to raise the first linear guide mechanism 161 to a certain height, so as to facilitate at least a portion of the first drive assembly 110 to be accommodated between the base and the connecting platform 120. The second support body 1621 is provided to facilitate at least a portion of the second drive assembly 130 to be accommodated between the connecting platform 120 and the movable positioning member 140. This is conducive to a compact structure.

[0062] In another embodiment of the present application, please refer to Figures 3 to 5 , the first drive assembly 110 includes a first motor 111 and a first screw-nut mechanism 112 for transmitting the power of the first motor 111 to the connecting platform 120; the second drive assembly 130 includes a second motor 131 and a second screw-nut mechanism 132 for transmitting the power of the second motor 131 to the movable positioning member 140. The drive assembly adopts a combination of a control motor and a screw-nut mechanism, which is easy to assemble and convenient for controlling the output displacement to adjust the position of the actuator. Specifically, the motor output shaft is connected to one end of the screw, the screw and the nut are threaded, and the nut is connected to the actuator as the output end of the drive assembly. When the motor is working, the rotation of the screw is converted into a linear displacement of the nut to drive the actuator to move linearly. The actuator here refers to the connecting platform 120 or the movable positioning member 140. In addition, the first motor 111 and the second motor 131 are arranged in the same direction and adjacent to each other, which facilitates the wiring operation of the motor.

[0063] In another embodiment of the present application, please refer to Figure 5The movable positioning member 140 includes a support plate 141 and a first L-shaped barrier arm 142 provided on the support plate 141, a support surface 140a is formed on the support plate 141, a first positioning surface 140c is formed on the first L-shaped barrier arm 142, and a guide groove 140b is provided on the support plate 141. The movable positioning member 140 is easy to form. The support plate 141 and the first L-shaped barrier arm 142 can be directly formed or assembled. The fixed positioning member 150 includes a support foot 151 and a second L-shaped barrier arm 152 connected to the support foot 151, and the second positioning surface 150a is formed on the second L-shaped barrier arm 152. The fixed positioning member 150 is easy to form. The support foot 151 can be mounted on the base by fasteners.

[0064] In another embodiment of the present application, please refer to Figure 3 , Figure 5 The guide block 130a is rotatably mounted on the output end of the second driving assembly 130 so that the guide block 130a can roll relative to the inner wall of the guide groove 140b. This solution is beneficial for the guide block 130a to move in the guide groove 140b, and for the guide block 130a to drive the movable positioning member 140 to slide linearly relative to the connecting platform 120.

[0065] In another embodiment of the present application, please refer to Figures 7 to 9 The transfer and lifting device includes: a transfer drive mechanism 210, a lifting drive mechanism 220 and a plurality of adsorption mechanisms 230. The transfer drive mechanism 210 includes a third drive component 211 and a first slide 212 driven by the third drive component 211 to move along the Y-axis direction. The lifting drive mechanism 220 includes a fourth drive component 221 mounted on the first slide 212, a second slide 222 slidably mounted on the first slide 212 along the Y-axis direction and driven by the fourth drive component 221 to move along the Y-axis direction, and a plurality of reversing components 223 equidistantly distributed along the Y-axis direction. The number of the reversing components 223 is one more than the number of the workstations 251. Each reversing assembly 223 includes a reversing seat 2231 fixed to the second slide 222, a movable frame 2232 slidably mounted on the reversing seat 2231 along a predetermined direction, and a limit frame 2234 mounted on the first slide 212 and used to limit the movement of the movable frame 2232 along the Z-axis direction. The sliding direction of the movable frame 2232 relative to the reversing seat 2231 forms an acute angle with the Y-axis direction, and the Y-axis direction and the Z-axis direction are perpendicular to each other. The adsorption mechanism 230 is mounted on each movable frame 2232 in a one-to-one correspondence, and each adsorption mechanism 230 has a semi-finished product suction nozzle 231 arranged upward. The support table 250 has a strip gap 252 extending along the Y-axis direction and for the movable frame 2232 to pass through, and the movable frame 2232 is arranged corresponding to the strip gap 252.

[0066] The reversing seat 2231, the movable frame 2232 and the limiting frame 2234 in the reversing assembly 223 cooperate to convert the Y-axis movement of the reversing seat 2231 into the Z-axis movement of the movable frame 2232. Figure 7 , Fig. 9 In the reversing assembly 223, the limit frame 2234 and the fourth driving assembly 221 are installed on the first slide 212, and the second slide 222 is slidably installed on the first slide 212 along the Y-axis direction. When the third driving assembly 211 drives the first slide 212 to move along the Y-axis direction, the first slide 212 drives the limit frame 2234, the fourth driving assembly 221 and all structures arranged on the second slide 222 to move along the Y-axis direction. The reversing seat 2231 is fixed on the second slide 222. When the fourth driving assembly 221 drives the second slide 222 to move along the Y-axis direction, the second slide 222 drives the reversing seat 2231 to move along the Y-axis direction. At this time, the movable frame 2232 slides on the reversing seat 2231 along a predetermined direction. The sliding direction of the movable frame 2232 relative to the reversing seat 2231 forms an acute angle with the Y-axis direction. The limiting frame 2234 limits the movable frame 2232 to move along the Z-axis direction, thereby realizing the movement of the movable frame 2232 along the Z-axis direction.

[0067] The third driving assembly 211 and the fourth driving assembly 221 enable the adsorption mechanisms 230 disposed on each movable frame 2232 to move in the Y-axis and Z-axis directions, thereby allowing the semi-finished products adsorbed by each adsorption mechanism 230 to be transferred synchronously. Fig.11 , the third driving assembly 211 and the fourth driving assembly 221 are set to output displacement at a predetermined time interval, so that the adsorption mechanism 230 on the movable frame 2232 can move along a predetermined path, and the adsorption mechanism 230 can adsorb or release the semi-finished product 20. A plurality of stations 251 are arranged above each reversing assembly 223 along the Y-axis direction. For example, the adsorption mechanism 230 first adsorbs a semi-finished product 20, and moves the adsorption mechanism 230 upward along the Z-axis direction by a predetermined displacement, then moves along the Y-axis direction by a predetermined displacement, and then moves downward along the Z-axis direction by a predetermined displacement, and the adsorption mechanism 230 releases the semi-finished product. This process is used to transfer the semi-finished product from one station 251 to another adjacent station 251; finally, the adsorption mechanism 230 moves in the reverse direction along the Y-axis direction to return to the previous station 251, thus completing a movement cycle; the same steps are performed later, so that the adsorption mechanism 230 can be continuously moved between the two stations 251 in a cycle, so that the semi-finished product 20 can be transferred from one station 251 to another adjacent station 251.

[0068] The support platform 250 is plate-shaped, and the support platform 250 is connected to a support leg 259, and the support leg 259 is installed on a base. The support platform 250 is arranged above the transfer and lifting device. The movable frame 2232 can pass through the strip gap 252 of the support platform 250, so as to facilitate the upward or downward movement of the adsorption mechanism 230 along the Z-axis direction, and the movement of the adsorption mechanism 230 along the Y-axis direction when the adsorption mechanism 230 is above the workstation 251.

The up-down driving mechanism 320 includes a sixth driving assembly 321 mounted on the first support 312, a second support 322 slidably mounted on the first support 312 along the X-axis direction and driven by the sixth driving assembly 321 to move along the X-axis direction, and a direction-changing assembly 323; each direction-changing assembly 323 includes a direction-changing seat 3231 fixed to the second support 322, a mounting frame 3232 slidably mounted on the direction-changing seat 3231 along a predetermined direction, and a stopper 3233 mounted on the first support 312 and used to limit the movement of the mounting frame 3232 along the Z-axis direction, the sliding direction of the mounting frame 3232 relative to the direction-changing seat 3231 forms an acute angle with the X-axis direction, and the X-axis direction and the Z-axis direction are perpendicular to each other. A plurality of adsorption assemblies 330 are mounted on the mounting frame 3232, and each adsorption assembly 330 has a film suction nozzle 331 arranged downward.

[0075] The direction-changing seat 3231, the mounting frame 3232 and the stopper 3233 in the direction-changing assembly 323 cooperate to convert the movement of the direction-changing seat 3231 in the X-axis direction into the movement of the mounting frame 3232 in the Z-axis direction.
