Description

Technical fields:

[0001] This invention relates to the technical field of display plastic component manufacturing apparatus, and more specifically to a display plastic component manufacturing equipment. Background technology:

[0002] A monitor is a computer's I / O device, or output device. It is a display tool that displays electronic documents onto a screen via a specific transmission device. Currently, monitors come in a variety of shapes and sizes. Some monitors have feet or stands at the bottom, allowing for proper placement. Our company previously proposed a strip-shaped insert-type monitor stand, patent number 202120421021.6. Its main body has an isosceles trapezoidal cross-section, and a T-shaped support bracket is inserted into the main body. The support bracket connects to the monitor. To facilitate the installation of the support bracket on the main body, corresponding slots are provided. An isosceles trapezoidal cover plate is provided at one end of the slot. The cover plate is fixed to the main body by adhesive to restrict the movement of the support bracket. Currently, the assembly of this insert-type monitor stand is mainly done manually. After the cover plate is glued to the main body, a clamp is needed to hold the main body and the cover plate together. Then, it is moved to a hot air drying station to accelerate the drying of the adhesive between the cover plate and the main body, ensuring the cover plate is firmly fixed to the main body before the clamp is removed. This manual assembly method of the monitor stand has low production efficiency. Therefore, it is necessary to design a corresponding mechanical structure to assist in the manual assembly of the monitor stand and improve production efficiency. Summary of the Invention:

One end of the tension spring 39 is fixedly connected to the positioning sleeve 38 and the other end is fixedly connected to the positioning plate 33;

[0020] Below the frame 1 in front of the conveying chain plate 2, a vertical glue-brushing roller 7 is fixedly connected opposite to the front end face of the fixed groove box 32; Behind the conveying chain plate 2, an L-shaped support frame 5 is fixedly connected to the frame 1. A set of longitudinal opening and closing components 4 opposite to the clamping racks 3 on the conveying chain plate 2 are fixedly connected to the support frame 5. The opening and closing component 4 includes a longitudinal opening and closing cylinder 42 fixedly connected to the support frame 5. The piston rod of the opening and closing cylinder 42 passes through the support frame 5 and is fixedly connected to a transverse push plate 41. The push plate 41 is located directly behind the T-shaped guide rod 34 on the clamping rack 3;

[0021] At the front end of the support frame 5 directly above the opening and closing component 4, a vertical cover plate conveying component 6 is fixedly connected. The cover plate conveying component 6 includes a lifting seat 61 abutted against the support frame 5. A vertical front guard plate 611 is formed at the front end of the lifting seat 61. An installation groove 612 penetrating the upper end face of the front guard plate 611 is formed on the rear end face of the upper part of the front guard plate 611. An avoidance notch 613 opposite to the pressing plate 37 is formed on the upper end face of the front guard plate 611; The rear end face of the front guard plate 611 abuts against an L-shaped rear guard plate 63. The upper end of the rear guard plate 63 is located directly behind the installation groove 612. A number of vertical T-shaped guide columns 64 are inserted into the rear guard plate 63. The lower ends of the guide columns 64 are inserted and fixed on the lifting seat 61. A compression spring 65 is inserted on the guide columns 64. Both ends of the compression spring 65 are respectively pressed against the rear guard plate 63 and the lifting seat 61. A vertical limiting column 66 is fixedly connected to the lifting seat 61. The limiting column 66 is inserted into the support frame 5. A vertical lifting cylinder 62 is fixedly connected to the support frame 5. The piston rod of the lifting cylinder 62 passes through the support frame 5 and is fixed on the lifting seat 61; The upper end of the rear guard plate 63 is located directly below the fixed groove box 32.

[0022] The width of the rear guard plate 63, the width of the lifting seat 61, and the width of the front guard plate 611 are equal. The width of the front guard plate 611 is less than the spacing between the T-shaped guide rods 34 on the clamping frame 3.

[0023] The distance between the positioning plate 33 and the positioning sleeve 38 on the clamping rack 3 is greater than the distance from the pressure plate 37 to the front end face of the fixed slot box 32.

[0024] The support frame 5 consists of a vertical part and a horizontal part. The vertical part of the support frame 5 is located behind the clamping rack 3, and the horizontal part of the support frame 5 is located below the clamping rack 3 on the lower side of the conveyor chain plate 2. The opening and closing assembly 4 is installed on the vertical part of the support frame 5, and the cover plate conveying assembly 6 is installed on the horizontal part of the support frame 5. An oblique support is fixed between the vertical part and the horizontal part of the support frame 5.

[0025] The rear end face of the front guard plate 611 of the cover plate conveying assembly 6 is flush with the front end of the fixed slot box 32.

[0026] The longitudinal distance between the front end face of the fixed groove box 32 and the glue-applying brush roller 7 is greater than the length of the brush on the glue-applying brush roller 7.

[0027] The slotted box 32 has a cavity with an isosceles trapezoidal cross-section. The cavity passes through the front and lower surfaces of the slotted box 32. The rear surface of the slotted box 32 abuts against a sealing plate covering the cavity. A screw is inserted into the upper end of the sealing plate and screwed into the slotted box 32. The sealing plate is hinged to the slotted box 32 by the screw. When the assembled monitor base needs to be removed from the slotted box 32, the sealing plate can be moved. Then, the pressure plate 37 on the clamping rack 3 will push the monitor base out from the rear side of the slotted box 32, and the assembled monitor base can be pulled out. The new main body 81 and support bracket 82 are inserted into the slotted box 32 from the rear end of the slotted box 32, and then the sealing plate is moved and closed.

[0028] Working principle: This invention is a production equipment for plastic components of displays. The production equipment for plastic components of displays uses a conveyor chain plate 2 as a conveying component. The conveyor chain plate 2 is equipped with a clamping rack 3. The main body 81 and the support bracket 82 of the display base can be inserted into the fixed slot box 32 of the clamping rack 3. The station for inserting the main body 81 and the support bracket 82 is also the station for picking up the completed display base (the front end of the main body 81 extends out of the fixed slot box 32), which can be completed manually.

[0029] Then, as the conveyor chain plate 2 runs, the main seat 81 passes through the glue-applying brush roller 7, which applies glue to the front end face of the main seat 81, and then moves to the opening and closing assembly 4.

[0030] Next, the opening and closing cylinder 42 on the opening and closing assembly 4 is activated, driving the push plate 41 to push the T-shaped guide rod 34 forward. Then, the lifting cylinder 62 on the cover plate conveying assembly 6 is activated. The lifting cylinder 62 moves the cover plate 83 held by the front guard plate 611 and the rear guard plate 63 upward. During the upward movement, the front guard plate 611 will stop moving due to the restriction of the fixed slot box 32, while the front guard plate 611 continues to convey the cover plate 83 upward (during this upward movement, the cover plate abuts against the front end of the main body 81). Then, when the cover plate 83 is in place, the opening and closing cylinder 42 is reset, and the pressure plate 37 is pressed against the front end surface of the main body 81 by the tension spring 39.

[0031] Then, the monitor base, pressed by the conveyor chain plate 2, moves to the hot air drying area, and finally moves to the starting position with the conveyor chain plate 2 to pick up the material.

[0032] The embodiments described are illustrative of the invention and are not intended to limit the invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
