Most of the existing film coating processes are off-line operations. After the operator tears off the bottom release film of the diaphragm and places the diaphragm on the lamp board, it is then put into a vacuum defoaming box to remove the bubbles between the diaphragm and the lamp board. Manual operation has low efficiency, high production instability, and the operator will be fatigued after long-term operation, posing a safety hazard. Content of the Utility Model:

[0015] The following elaborates on the present utility model in combination with the drawings and embodiments:

[0016] Figures 1 - 4 As shown, it is an embodiment of the present utility model.

[0017] A diaphragm loading mechanism includes a fixed machine table 1. A moving platform assembly 2 is provided on the fixed machine table 1. A working platform 3 and a positioning assembly 4 and a lifting component 5 are provided on the moving platform 21 of the moving platform assembly 2. Among them, the moving platform assembly 2 moves between the loading station and the unloading station. The positioning assembly 4 positions the workpiece 6 on the working platform 3, and the lifting component 5 drives the working platform 3 to lift and lower to cooperate with the manipulator to pick up the workpiece.

[0018] In a specific embodiment, the mobile platform assembly 2 includes a mutually cooperating mobile cylinder 22, a mobile platform 21, a guide rail assembly 23, and a cylinder in-place sensor 24; wherein, the mobile cylinder 22, the guide rail assembly 23, and the cylinder in-place sensor 24 are respectively arranged on a fixed machine table, the mobile platform 21 is installed on the mobile end of the mobile cylinder 22 and is driven by it to move, a chute is provided under the mobile platform 21 and cooperates with the guide rail assembly 23 to move along the guide rail assembly 23, and the cylinder in-place sensor 24 cooperates with the mobile platform 21 to sense its position and control the action of the mobile cylinder 22.

[0019] The positioning assembly 4 includes a mutually cooperating X-axis dovetail chute 41, an X-axis baffle 42, a Y-axis dovetail chute 43, a Y-axis baffle 44, and a brush assembly 45; wherein, the X-axis dovetail chute 41 and the Y-axis dovetail chute 42 are fixed in the vertical direction on the mobile platform 21, the X-axis baffle 42 and the Y-axis baffle 44 respectively move along the X-axis dovetail chute 41 and the Y-axis dovetail chute 43 to the position where they fit the workpiece to position the workpiece 6, and the brush assembly 45 is fixed on the mobile platform 21 and cooperates with the workpiece 6 to prevent multiple workpieces from sticking together.

[0020] The lifting assembly 5 includes a mutually cooperating brake servo motor 51, a coupling (not shown in the figure), a ball screw assembly 52, a diaphragm in-place sensor 53, a diaphragm material shortage alarm sensor 54, and a diaphragm material availability sensor 55; wherein, the brake servo motor 51 and the coupling are installed on the mobile platform, the brake servo motor 51 is energized and drives the ball screw assembly 52 to rotate through the coupling, the ball screw assembly 52 cooperates with the work platform 3 to drive the work platform 3 to lift, and the diaphragm in-place sensor 53, the diaphragm material shortage alarm sensor 54, and the diaphragm material availability sensor are installed on the work platform 3 to sense the position of the diaphragm and control the action of the brake servo motor 51.

[0021] During operation, an operator places several diaphragms (workpiece 6) on the working platform. The diaphragm presence sensor is triggered. The operator adjusts the positioning component according to the size of the diaphragm to position the workpiece. After pressing the start button, the moving cylinder of the moving platform assembly operates to move the moving platform to the working position. The cylinder in-place sensor triggers a signal, and the lifting component starts working. The brake servo motor is powered on and drives the ball screw to rotate through the coupling, thereby driving the working platform to rise. After the working platform rises to the in-place position, the diaphragm in-place sensor triggers a signal, and the platform stops moving. The manipulator adsorbs one PCS of diaphragm. The film separating brush assembly prevents multiple diaphragms from sticking together. After taking away one or several diaphragms each time, the diaphragm in-place sensor fails to sense the material and disconnects the signal. The working platform rises by a fixed stroke until the diaphragm in-place sensor triggers the signal again, and the platform stops moving and continues to pick up diaphragms in a cycle. When the platform rises to a certain height, the diaphragm material shortage alarm sensor triggers a signal to remind the operator to prepare for replenishing materials. The diaphragm presence sensor disconnects the signal, indicating that all the diaphragms on the platform have been taken away. The working platform descends to the lowest position, and the moving cylinder retracts to the manual replenishing position. The cylinder in-place sensor triggers a signal. After the manual replenishment is completed, the next cycle is carried out.

When the loading mechanism is seamlessly connected to manufacturing equipment, automatic control of the entire production process can be realized, saving human resources and manufacturing costs.

It can store about 500 PCS of materials at one time; has high compatibility and can be compatible with various specifications of materials; monitors the quantity of materials and gives a shortage warning.
