[0002] In the production of optical display screens, FOB binding machines are widely used in the production and maintenance of various liquid crystal and optical display panels. FOB is a processing method that first bonds the PCB (flexible printed circuit board) with the ACF film (anisotropic conductive film), and then hot presses it at a certain temperature and pressure to achieve mechanical connection and electrical conduction between the glass of the display screen and the PCB (flexible printed circuit board).

[0003] In the prior art, a binding machine is usually used to fix the driver chip on the glass substrate. The vacuum adsorption table on the binding machine is usually fixed on the frame. When a large-sized glass substrate needs to be bound, it is particularly inconvenient.

[0007] Furthermore, the machine body is arranged in the middle of the base, and a top block is fixedly extended on the bottom plane of the "concave" structure of the base.

[0008] Furthermore, a servo motor is built into the bottom recess of the "concave" structure of the base, and a gear column turntable is fixedly connected to the top output end of the servo motor, and the gear columns on the gear column turntable surface intermittently mesh with the teeth on the inner walls on both sides of the bidirectional gear plate.

[0009] Furthermore, side seats are symmetrically fixed on both sides of the top of the "concave" structure of the base, and electromagnets are fixed on the inner walls of the opposite recesses of the side seats, and the electromagnetic force generated by the electromagnets when energized is greater than the magnetic attraction of the permanent magnet.

[0010] Furthermore, an extended liquid crystal carrier is movably embedded in the recesses on the opposite surfaces of the side seats on both sides, and a docking tube is fixedly connected to the middle of the side of the extended liquid crystal carrier facing the core liquid crystal carrier, and the docking tube forces the torsion spring flap to open so that the internal cavity of the extended liquid crystal carrier is connected to the internal cavity of the body.

[0011] Furthermore, positioning grooves are provided at both ends of the extended liquid crystal carrier on one side facing the core liquid crystal carrier, and the extended liquid crystal carrier is engaged with the positioning seats at corresponding positions of the core liquid crystal carrier through the positioning grooves and is fixed by magnetic attraction.

[0012] Furthermore, the base is connected to the output end of the synchronous drive component, and the synchronous drive component includes a threaded seat, side panels, guide bars, a movable seat and a top groove.

[0016] The present invention provides a binding machine for liquid crystal screen manufacturing, which has the following beneficial effects:

[0017] 1. During the use of the present invention, the present application additionally installs a bidirectional toothed plate on the bottom plane of the body of the core liquid crystal carrier. Under the drive of the servo motor, the toothed column of the toothed column turntable intermittently meshes with the toothed shape of the inner wall on both sides of the bidirectional toothed plate, so that the core liquid crystal carrier can be located on the "concave" structure of the base and move horizontally left and right. The left and right movement of the core liquid crystal carrier makes the positioning seats on both sides of its end engage with the positioning grooves at the ends of the adjacent extended liquid crystal carriers, and the core liquid crystal carrier and the extended liquid crystal carrier are magnetically fixed by the permanent magnets inside the positioning seats. At the same time, the core liquid crystal carrier and the two connected extended liquid crystal carrier cavities synchronously generate a vacuum environment.

[0018] 2. During the use of the present invention, the present application, through the setting of the synchronous drive component, not only only needs to set up one driving motor, but also can sequentially complete the forward movement and lifting action under the coordinated action of the front and rear double cams, so that the liquid crystal glass to be processed can be moved forward to the processing station of the machine and continuously lifted to complete the pressing operation. The setting of the double cams not only effectively guarantees the repeatability of the forward movement and lifting action required for the above-mentioned binding operation, but also integrates the material collection and pressing process originally integrated on the machine into the transplanting table of the present application, so that the machine only needs to have the feeding function of different materials, which greatly reduces the production cost;

[0019] 3. During the use of the present invention, when a single small-sized liquid crystal glass is bound, the liquid crystal glass to be processed is firmly adsorbed on the core liquid crystal carrier through the pores on the orifice plate, and when multiple small-sized liquid crystal glasses are bound, or a single large-sized liquid crystal glass is bound, the core liquid crystal carrier of the present application can adapt to the synchronous operation requirements of multiple small-sized liquid crystal glasses and the multi-station operation requirements of a single large-sized liquid crystal glass through the extended liquid crystal carriers additionally installed on both sides. Moreover, because the electromagnetic force generated by the electromagnet when it is energized is greater than the magnetic attraction of the permanent magnet, during the left and right horizontal movement of the core liquid crystal carrier, the extended liquid crystal carriers on both sides can detach from the core liquid crystal carrier in the middle by themselves, and the entire process is automatically operated without manual intervention, thereby greatly improving the efficiency of automated production.

DETAILED DESCRIPTION

[0028] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0029] See also Figures 1 to 7The present invention provides a technical solution: a binding machine for liquid crystal screen manufacturing, including a core liquid crystal carrier 1, the core liquid crystal carrier 1 includes a body 101, a hole plate 102, a vacuum interface 103, a docking interface 104, a torsion spring flap 105, a positioning seat 106, a permanent magnet 107 and a bidirectional tooth plate 108, the top of the opening of the body 101 is sealed and fixed with the hole plate 102, and the front of the cavity of the body 101 is connected to the vacuum pump through the vacuum interface 103, and the cavity of the body 101 is opened on both sides. There is a docking port 104, and a torsion spring flap 105 is rotatably installed on the inner side of the opening of the docking port 104. Positioning seats 106 are fixedly installed on both sides of the outside of the body 101, and permanent magnets 107 are embedded in the positioning seats 106. A two-way tooth plate 108 is fixedly installed at the bottom of the body 101, and the inner walls on both sides of the hollow cavity of the two-way tooth plate 108 are symmetrically arranged with teeth. The body 101 is set in the middle of the base 2, and the bottom plane of the "concave" structure of the base 2 is fixedly extended with a top block 3, and the base 2 is "concave" A servo motor 4 is built into the bottom recess of the "concave" structure, and a gear column turntable 5 is fixedly connected to the top output end of the servo motor 4, and the gear columns on the surface of the gear column turntable 5 are intermittently meshed with the teeth of the inner walls of the two sides of the bidirectional gear plate 108, and side seats 6 are symmetrically fixed on both sides of the top of the "concave" structure of the base 2, and electromagnets 7 are fixed on the inner walls of the opposite recesses of the side seats 6, and the electromagnetic force generated by the electromagnets 7 when powered on is greater than the magnetic attraction of the permanent magnet 107, and an extended liquid crystal carrier 8 is movably embedded in the opposite recesses of the side seats 6 on both sides, and a docking pipe 9 is fixedly connected to the middle of the side of the extended liquid crystal carrier 8 facing the core liquid crystal carrier 1, and the docking pipe 9 forces the torsion spring flap 105 to open so that the internal cavity of the extended liquid crystal carrier 8 is connected to the internal cavity of the body 101, and positioning grooves 10 are provided at both ends of the side of the extended liquid crystal carrier 8 facing the core liquid crystal carrier 1, and the extended liquid crystal carrier 8 is snap-fitted with the positioning seat 106 at the corresponding position of the core liquid crystal carrier 1 through the positioning groove 10 and fixed by magnetic attraction;

[0030] The specific operation is as follows: when a single small-sized liquid crystal glass is bound, the liquid crystal glass to be processed is placed on the core liquid crystal carrier 1, and the inner cavity of the body 101 is connected to the vacuum pump through the vacuum interface 103, and then the liquid crystal glass to be processed is firmly adsorbed on the orifice plate 102 through the air holes on the orifice plate 102. When a plurality of small-sized liquid crystal glasses are bound, or a single large-sized liquid crystal glass is bound, the size of the liquid crystal glass exceeds the original bearing area of ​​the core liquid crystal carrier 1, so the present application additionally installs a bidirectional tooth plate 10 on the bottom plane of the body 101 of the core liquid crystal carrier 1. 8. Driven by the servo motor 4, the toothed columns on the toothed turntable 5 intermittently mesh with the teeth on the inner walls of the two sides of the bidirectional toothed plate 108, so that the core liquid crystal carrier 1 can be located on the "concave" structure of the base 2 and move horizontally to the left and right. In the initial stage without the installation of the liquid crystal glass, the horizontal movement of the core liquid crystal carrier 1 makes the positioning seats 106 on both sides of its ends engage with the positioning grooves 10 at the ends of the adjacent extended liquid crystal carrier 8, and the core liquid crystal carrier 1 and the extended liquid crystal carrier 8 are magnetically fixed by the permanent magnets 107 inside the positioning seats 106. At the same time, the docking pipes 9 at the ends of the extended liquid crystal carrier 8 are connected by the magnetic fixing. The torsion spring flap 105 is forced to open so that the internal cavity of the extended liquid crystal carrier 8 is connected to the internal cavity of the core liquid crystal carrier 1, so that the core liquid crystal carrier 1 and the two connected extended liquid crystal carriers 8 are synchronously generated with the internal cavity of the vacuum environment, which is used to adapt to the loading requirements of multiple small-sized or single large-sized liquid crystal glasses. In the processing stage where the liquid crystal glasses have been installed, the left and right lateral movement of the core liquid crystal carrier 1 enables the driver chips located at different positions thereon to be pressed in sequence, so that the core liquid crystal carrier 1 of the present application can adapt to multiple small-sized liquid crystal glasses through the additionally installed extended liquid crystal carriers 8 on both sides and the left and right reciprocating lateral movement. The synchronous operation requirements of the 2-inch liquid crystal glass and the multi-station operation requirements of a single large-size liquid crystal glass further improve the applicability and processing efficiency of the device. When it is necessary to restore the independent operation state of the core liquid crystal carrier 1, it is only necessary to energize the electromagnet 7 on the inner wall of the recess of the side seat 6 to generate magnetism. Because the electromagnetic force generated by the electromagnet 7 when it is energized is greater than the magnetic attraction of the permanent magnet 107, during the left and right lateral movement of the core liquid crystal carrier 1, the extended liquid crystal carriers 8 on both sides can be separated from the core liquid crystal carrier 1 in the middle by themselves, and the whole process is automatically operated without manual intervention, which greatly improves the efficiency of automated production.

[0031] See also Figures 2 to 3The base 2 is connected to the output end of the synchronous drive component 11. The synchronous drive component 11 includes a threaded seat 1101, a side plate 1102, a guide bar 1103, a moving seat 1104 and a top groove 1105. The side plates 1102 are symmetrically fixed on both sides of the top of the threaded seat 1101, and the guide bar 1103 is fixed on the inner side of the side plate 1102. The moving seat 1104 is slidably installed on the outside of the guide bar 1103, and the end of the moving seat 1104 is provided with a top groove 1105 that slides with the top block 3. The synchronous drive component 11 also includes a reset spring 1106 and a driven wheel 1107. The side end of the moving seat 1104 is elastically connected to the end boss of the guide bar 1103 through the reset spring 1106, and the bottom of the side end of the moving seat 1104 is fixedly connected to the driven wheel 1107. The synchronous drive component 11 It also includes a driving motor 1108, a shaft 1109, a rear cam 1110 and a front cam 1111. The driving motor 1108 is fixed to the outside of the side plate 1102, and the output end of the driving motor 1108 is fixedly connected to the shaft 1109, the rear end of the shaft 1109 is coaxially connected to the rear cam 1110, and under the elastic force of the return spring 1106, the outer edge of the rear cam 1110 is always tightly fitted with the rim of the driven wheel 1107, the front end of the shaft 1109 is coaxially connected to the front cam 1111, and under the action of gravity, the outer edge of the front cam 1111 is always tightly fitted with the bottom plane of the top block 3, the screw hole in the middle of the threaded seat 1101 is matched with the ball screw 12, and the ball screw 12 is connected to the output end of the screw motor 13, and the screw motor 13 is fixed to one end of the workbench 14;

[0032] The specific operation is as follows: the threaded seat 1101 is matched with the thread of the ball screw 12, and is moved on the workbench 14 under the drive of the screw motor 13, so that the liquid crystal glass to be processed is circulated between the processing stations to complete the binding operation. During the processing, on the one hand, the driving motor 1108 rotates and drives the rear cam 1110 coaxially with the rear end of the shaft rod 1109, so that the outer edge of the rear cam 1110 squeezes the driven wheel 1107 at the bottom of the side end of the moving seat 1104, so that the moving seat 1104 is located on the guide bar 1103 and slides forward, and the liquid crystal glass to be processed is extended from the turnover position on the workbench 14 to the processing station of the corresponding machine. On the other hand, the driving motor 1108 rotates and drives the front cam 1111 coaxially with the front end of the shaft rod 1109, so that the outer edge of the front cam 1111 squeezes the top block 3. The bottom plane causes the top block 3 to slide and lift in the top groove 1105 at the end of the moving seat 1104, so that the liquid crystal glass to be processed is lifted on the processing station of the corresponding machine and pressed with the FPC and other materials to complete the binding operation. The present application uses the setting of the synchronous drive component 11, which not only requires the setting of one drive motor 1108, but can complete the forward movement and lifting actions in sequence under the coordinated action of the front and rear double cams, so that the liquid crystal glass to be processed can be moved forward to the processing station of the machine and continuously lifted to complete the pressing operation. The setting of the double cams not only effectively guarantees the repeatability of the forward movement and lifting actions required for the above-mentioned binding operation, but also integrates the material picking and pressing process originally integrated on the machine into the transplanting table of the present application, so that the machine only needs to have the feeding function of different materials, which greatly reduces the production cost.

[0033] In summary, when using the binding machine for LCD screen manufacturing, when performing a binding operation on a single small-sized liquid crystal glass, the liquid crystal glass to be processed is placed on the core liquid crystal carrier 1, and the inner cavity of the machine body 101 is connected to the vacuum pump through the vacuum interface 103, and then the liquid crystal glass to be processed is firmly adsorbed on the orifice plate 102 through the air holes on the orifice plate 102. When in use, the threaded seat 1101 cooperates with the thread of the ball screw 12, and is moved on the workbench 14 under the drive of the screw motor 13, so that the liquid crystal glass to be processed is circulated between the various processing stations to complete the binding operation. During the processing, on the one hand, the driving motor 1108 rotates and drives the rear cam 1110 coaxially with the rear end of the shaft 1109, so that the outer edge of the rear cam 1110 squeezes The driven wheel 1107 at the bottom of the side end of the movable seat 1104 is pressed, so that the movable seat 1104 slides forward on the guide bar 1103, and the liquid crystal glass to be processed is extended from the turnover position on the workbench 14 into the processing station of the corresponding machine. On the other hand, the driving motor 1108 rotates and transmits the front cam 1111 coaxially with the front end of the shaft rod 1109, so that the outer edge of the front cam 1111 squeezes the bottom plane of the top block 3, so that the top block 3 is located in the top groove 1105 at the end of the movable seat 1104 and slides and lifts, so that the liquid crystal glass to be processed is lifted on the processing station of the corresponding machine, and is pressed with the FPC and other materials to complete the binding operation. The present application adopts the setting of the synchronous driving component 11, not only only the setting of the driving motor 1108 is required, but also the setting of the front cam 1111 is also required. The arrangement of the double cams can complete the forward movement and lifting movements in sequence under the coordinated action of the front and rear double cams, so that the liquid crystal glass to be processed can be moved forward to the processing station of the machine and continuously lifted to complete the pressing operation. The arrangement of the double cams not only effectively guarantees the repetitive accuracy of the forward movement and lifting movements required for the above-mentioned binding operation, but also integrates the material picking and pressing process originally integrated on the machine into the transplanting table of the present application, so that the machine only needs to have the loading function of different materials, which greatly reduces the production cost. When performing the binding operation of multiple small-sized liquid crystal glasses or the binding operation of a single large-sized liquid crystal glass, the size of the liquid crystal glass exceeds the bearing area of ​​the original core liquid crystal carrier 1. Therefore, the present application additionally installs a bottom plane of the body 101 of the core liquid crystal carrier 1 There is a bidirectional tooth plate 108. Under the drive of the servo motor 4, the tooth column on the tooth column turntable 5 is intermittently meshed with the tooth shape of the inner wall on both sides of the bidirectional tooth plate 108, so that the core liquid crystal carrier 1 can be located on the "concave" structure of the base 2 and move horizontally to the left and right. In the initial stage without the installation of liquid crystal glass, the left and right movement of the core liquid crystal carrier 1 makes the positioning seats 106 on both sides of its end engage with the positioning grooves 10 at the end of the adjacent extended liquid crystal carrier 8, and the permanent magnets 107 inside the positioning seats 106 are used to achieve magnetic fixation of the core liquid crystal carrier 1 and the extended liquid crystal carrier 8. At the same time, the docking tube 9 at the end of the extended liquid crystal carrier 8 forces the torsion spring flap 105 to open so that the internal cavity of the extended liquid crystal carrier 8 is connected with the internal cavity of the core liquid crystal carrier 1.Thus, the core liquid crystal carrier 1 and the two connected extended liquid crystal carriers 8 on both sides can simultaneously generate a vacuum environment inside the cavity, which is used to adapt to the loading requirements of multiple small-sized or single large-sized liquid crystal glasses. In the processing stage where the liquid crystal glass has been installed, the left and right lateral movement of the core liquid crystal carrier 1 enables the driver chips located at different positions on it to be pressed in sequence, so that the core liquid crystal carrier 1 of the present application can adapt to the synchronous operation requirements of multiple small-sized liquid crystal glasses and the multi-station operation requirements of a single large-sized liquid crystal glass through the additional extended liquid crystal carriers 8 installed on both sides and the left and right reciprocating lateral movement, further improving the applicability and processing efficiency of the device. When it is necessary to restore the independent operation state of the core liquid crystal carrier 1, it is only necessary to energize the electromagnet 7 on the inner wall of the recess of the side seat 6 to generate magnetism. Because the electromagnetic force generated by the electromagnet 7 when it is energized is greater than the magnetic attraction of the permanent magnet 107, during the left and right lateral movement of the core liquid crystal carrier 1, the extended liquid crystal carriers 8 on both sides can be separated from the core liquid crystal carrier 1 in the middle by themselves, and the whole process is automatically operated without manual intervention, which greatly improves the efficiency of automated production.
