Description

Technical Field

[0001] This utility model relates to the technical field of light-shielding sheet feeding, specifically to a light-shielding sheet feeding assembly. Background Technology

[0002] The prism assembly includes a prism base, a roof prism, a light-blocking plate, a semi-pentagonal prism, and a retaining ring. The retaining ring and the prism base are each provided with screw holes, and the two are fixed together by mortise screws.

[0003] In the existing technology, light-shielding sheets are fed using a material tray. Specifically, several light-shielding sheets are placed in the material cavity of the material tray, and a multi-axis robotic arm is used to load the light-shielding sheets into the prism assembly. However, this feeding method has the following drawbacks: the material cavities are arranged in an array on the material tray on the horizontal plane, resulting in a large area occupied by the material tray and a small number of sheets that can be accommodated. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a light-shielding sheet feeding assembly.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A light-shielding sheet feeding assembly, comprising:

[0007] Base;

[0008] The hopper is detachably mounted on the base and has a vertically oriented trough for stacking light-shielding sheets. The trough has a vertically arranged guide rod and a lifting guide sleeve coaxially mounted on the guide rod. Several light-shielding sheets are stacked on the lifting guide sleeve. The lifting guide sleeve has a horizontal bar extending outward in the horizontal direction. The trough has an anti-airway groove in the vertical direction.

[0009] The lifting structure, located on the base, includes a first drive and a lifting arm. One end of the lifting arm is connected to the first drive, and the other end extends towards the side near the hopper and has an assembly slot with an open top. One end of the crossbar passes through the clearance slot and its end is detachably placed in the assembly slot. The first drive can drive the lifting arm to move vertically.

[0010] The fixture structure is located on the base, and a slot is provided on the top for placing the light-shielding sheet;

[0011] A transfer structure, disposed on the base, acts on the light-shielding sheet and is capable of transferring the light-shielding sheet located in the material trough to the empty trough.

[0012] Preferably, the base has an open-top assembly slot, and the bottom of the hopper is adapted to the assembly slot, allowing it to be inserted into or removed from the assembly slot in the vertical direction.

[0013] Preferably, the lifting guide sleeve is T-shaped and includes a support block for supporting several light-shielding sheets and two oppositely arranged crossbars. The support block has a guide hole that slides with the guide bar. The lifting arm is U-shaped and has two assembly slots on the side near the hopper.

[0014] Preferred options also include:

[0015] A material monitoring structure is located at the top of the silo to monitor whether there is a light-shielding plate at the top of the trough. When there is a light-shielding plate at the top of the trough, the transfer structure transfers the light-shielding plate to the empty trough. When there is no light-shielding plate at the top of the trough, the first drive drives the lifting guide sleeve to rise upward through the lifting arm until the light-shielding plate is detected by the material monitoring structure.

[0016] Preferably, the material monitoring structure includes:

[0017] A pair of fiber optic supports, wherein the fixture structure is a columnar body of the same height as the hopper, and the pair of fiber optic supports are disposed on the top of the fixture structure;

[0018] An optical fiber transmitter, wherein the fixed end of the optical fiber support is fixedly connected to the fixture structure, and the free end extends toward the end near the hopper and is connected to the optical fiber transmitter;

[0019] The fiber optic receiver has a fixed end that is fixedly connected to the fixture structure, and a free end that extends toward the end near the hopper and is connected to the fiber optic receiver.

[0020] Preferably, the lifting structure further includes:

[0021] A lifting bracket is mounted on the base and slidably connected to a lifting slider, which is fixedly connected to the lifting arm.

[0022] A ball nut is provided on the lifting slider. The first drive is a lead screw stepper motor provided on the lifting bracket. The output end of the lead screw stepper motor is connected to the ball nut for transmission, thereby driving the lifting arm to achieve lifting through the lifting slider.

[0023] Preferred options also include:

[0024] A guide rail is provided vertically on the lifting bracket, and the lifting slider is slidably connected to the lifting bracket through the guide rail.

[0025] Preferred options also include:

[0026] At least two miniature photoelectric switches are sequentially arranged on the lifting bracket along the vertical direction;

[0027] The sensing element is fixed to the side of the lifting slider.

[0028] Preferably, the transfer structure includes:

[0029] A horizontal slider slides in conjunction with the base in the horizontal direction;

[0030] The lifting seat is fixed on the horizontal slider;

[0031] The vertical slider slides in a vertical direction with the lifting seat;

[0032] The material handling plate has one end fixedly connected to the vertical slider and the other end equipped with a suction nozzle that acts on the light-shielding sheet.

[0033] Preferred options also include:

[0034] The second drive is located on the base and is connected to the horizontal slider in a transmission manner, and can drive the horizontal slider to move back and forth in the horizontal direction.

[0035] The third drive is located on the lifting seat and is connected to the vertical slider in a transmission manner, capable of driving the vertical slider to move back and forth in the vertical direction.

[0036] The beneficial effects of this utility model are as follows: During material preparation, the guide rod is inserted into the holes of several light-shielding sheets, and the light-shielding sheets are stacked vertically in the material trough, changing the horizontal placement method to vertical stacking. This increases the capacity of the light-shielding sheets without increasing the area occupied by the silo, which helps to reduce the frequency of silo replacement. During operation, the lifting arm drives the lifting guide sleeve to move vertically, pushing the stacked light-shielding sheets upward and cooperating with the transfer structure to transfer individual light-shielding sheets into the fixture structure. During assembly, the adsorption end of the external multi-axis robotic arm moves to the empty slot of the fixture structure to realize the removal of individual light-shielding sheets. Compared with the prior art, the multi-axis robotic arm picks up the same material position each time, which helps to simplify the programming of the robotic arm and reduce the reserved space for the robotic arm's movement.
