Embodiment 1

[0044] In order to solve the problem of BL self-assembly, the prism sheet must be torn off inside the machine 400 due to its easy contamination, and the film accumulates in the film receiving area, blocking the vent hole at the bottom of the machine 400, thereby disturbing the top-down airflow of the lens unit , forming a turbulent flow, causing the foreign matter on the film to disturb in the air and fall to the lens after the film is torn off, so that the assembled BL has white spots, black spots, white stripes (pollution or scratches), or water dancing and other defective products, and the defects caused by prism sheets are extremely difficult to repair, and can only be repaired by replacing new prism sheets, and the maintenance cost is high, and the demand for human resources is large. Therefore, this embodiment provides a solution to BL from the source. In the automatic assembly line, the film frame 100 with bad problems caused by the introduction of foreign matter in the ...

Embodiment 2

[0069] This embodiment provides a push pedal assembly with the function of auxiliary film installation. The difference between the push pedal assembly of this embodiment and the above-mentioned embodiment 1 is that it also includes an auxiliary push assembly:

[0070] In order to enable the push plate to push the lens film in the film stacking frame into the garbage bag as much as possible, an auxiliary pushing mechanism 130 is also provided on the pushing film plate 111. The auxiliary pushing mechanism 130 includes an auxiliary pushing plate 131, a shearing structure 132, a guide Seat 133 and transmission part 134, the horizontal installation groove 135 that runs through arc surface 1112 is provided on the pushing film plate 111, is provided with driving motor, the driving gear that is fixed on the output shaft of driving motor in the horizontal installation groove 135; 132 is used to drive the auxiliary push plate 131 to extend or retract.

[0071] The guide seat 133 is fixe...

Embodiment 3

[0078] This embodiment also discloses a control system for an automatic film harvesting mechanism, including:

[0079]The pressure sensor 422 is fixed on the inside of the dodge door 420, and is used to detect the pressure information between the push plate and the dodge door 420, and feed back the detected pressure information to the controller;

[0080] a controller, set in the control area of ​​the machine 400, for receiving and processing pressure information;

[0081] The servo motor is connected to the signal output end of the controller through the motor driver, and is used to control the working state of the push film plate 111 through the controller;

[0082] The electromagnetic lock 421 is arranged at the bottom of the film outlet 410 and is connected to the signal output end of the controller for opening and closing the movable door 420 according to the pressure information received by the controller;

[0083] The controller is PLC control system;

[0084] The pre...

Abstract

The invention relates to a pushing plate assembly with an auxiliary film assembly function. The pushing plate assembly with the auxiliary film assembly function comprises a film pushing plate, the first side wall of the film pushing plate is an arc-shaped surface protruding towards a film outlet, bristles are evenly distributed at the lower end of the arc-shaped surface, a horizontal installing groove penetrating through the arc-shaped face is formed in a pushing plate, an auxiliary pushing mechanism is arranged in the horizontal installing groove and comprises an auxiliary pushing plate, a shearing structure, a guiding base and a transmission part, the guiding base is fixed in the horizontal installing groove, the transmission part is arranged on the guiding base in a sliding mode, the shearing structure comprises a first telescopic unit, one end of the first telescopic unit is movably connected with the guiding base, the other end of the first telescopic unit is movably connected with the transmission part, the auxiliary pushing plate is arranged on the outer side of the film pushing plate and is fixedly connected with the free end of the shearing structure. According to the pushing plate assembly, residual films located at the film outlet can be further pushed out through the auxiliary pushing mechanism, so that the films are prevented from being accumulated at the film outlet, it is guaranteed that a door at the film outlet can be completely closed, and the positive pressure environment in a machine table is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of production auxiliary equipment in the manufacturing process of the electronics industry, and in particular relates to a push plate assembly with the function of auxiliary film installation. Background technique [0002] Electronic display modules generally include backlight modules and panels. Backlight modules have gradually entered a fully automated assembly mode. Backlight modules (BL) generally include: backplane, reflector, light guide plate, lower diffuser, prism, upper The diffuser and the card frame used to fix the above-mentioned reflective sheet, light guide plate, lower diffuser, prism sheet, and upper diffuser are also called plastic frames; [0003] In order to reduce defects after assembly, it is necessary to clean the various components of the backlight module through the automatic feeding mechanism and cleaning mechanism during the assembly of the assembly line. Since the prism sheet is ea...
