[0002] Automobile sun visors are generally first formed into a complete frame through injection molding, and then the edge wrapping technology is used. Edge wrapping is an important step to improve the appearance and durability of the edge of the sun visor. In the early days, it was mostly dependent on manual operation, but with the development of automation technology, the application of automated edge wrapping machines, hot melt adhesive laminating machines and other equipment has significantly improved efficiency and finished product quality.

[0003] In the prior art, for example, the invention patent with publication number CN109747168B can be pre-fixed when the sun visor frame is hemmed, thereby facilitating the later pressing and positioning of the sun visor frame and significantly improving work efficiency; however, since the fabric is located below the frame during the heat-sealed hemming, when the fabric is not fully stretched, wrinkles or waves are formed during the heat-sealing process, affecting the appearance quality of the finished product, and if there are air bubbles or gaps between the fabric and the frame, they cannot be fully fitted during heat sealing, which may lead to a decrease in bonding strength, and degumming or tearing may occur during long-term use, and frequent hemming quality problems require additional rework or scrapping, which prolongs the production cycle and reduces overall production efficiency.

DETAILED DESCRIPTION

[0049] See also Figure 1-Figure 6 In an embodiment of the present invention, a passenger car sun visor assembly processing device includes:

[0050] The heat sealing machine 1 has a bottom plate 11 fixed horizontally inside;

[0051] There are two hot pressing molds 12 arranged on the left and right. The two hot pressing molds 12 are used to horizontally position the sun visor frame that has been preliminarily processed. The two sun visor frames can be assembled into a group and hot pressed at the same time, which can greatly shorten the time of a single product in the hot pressing process, thereby producing more finished products per unit time and improving the overall efficiency of the production line.

[0052] A pressing plate mechanism 2 is horizontally arranged in the heat sealing machine 1 and is located directly above the bottom plate 11. A power plate 21 is arranged on the pressing plate mechanism 2;

[0053] The upper template 13 is arranged corresponding to the hot pressing mold 12. The upper template 13 is fixed to the lower end surface of the pressing plate mechanism 2. The upper template 13 cooperates with the hot pressing mold 12 to hot press the punched fabric onto the sun visor frame, so that the punched fabric and the sun visor frame are formed as a whole; the sun visor frames in the two hot pressing molds 12 are subsequently docked and assembled after the hot pressing operation is completed;

[0054] The film support unit 3 is distributed in the pressing plate mechanism 2 and is located at the edge of the hot pressing mold 12. The film support unit 3 is used to extend the side of the punched fabric on the hot pressing mold 12 so that the punched fabric is fully unfolded and laid flat on the surface of the sun visor frame, effectively improving the quality of the finished sun visor and avoiding the formation of wrinkles or waves in the punched fabric due to incomplete stretching during the heat sealing process;

[0055] The film support unit 3 comprises:

[0056] Inner mounting grooves 31 are equidistantly arranged in the pressing plate mechanism 2, and the inner mounting grooves 31 are arranged and distributed at the edge positions of the upper template 13;

[0057] A track frame 32 is horizontally fixed on the inner wall of the inner mounting groove 31, and a slider 33 is slidably connected to the track frame 32;

[0058] The rubber pressing plate 34 is horizontally installed below the slider 33 and slides laterally along the track frame 32 along with the slider 33;

[0059] A regulating unit 4 is fixed above the slider 33, and a side guide block 35 is installed on one side of the regulating unit 4;

[0060] The inner pressure plate 5 is installed in the pressing plate mechanism 2. A plurality of vertically fixed guide rods are arranged in the pressing plate mechanism 2. The inner pressure plate 5 is slidably connected with the guide rods. A lifting spring 51 is sleeved on the guide rods below the inner pressure plate 5. A convex edge is arranged on the inner pressure plate 5. One end face of the convex edge contacts the side guide block 35, and the contact surface is set to an inclined structure, so that when the inner pressure plate 5 is pressed down and slid, the side guide block 35 pushes the slider 33 to slide in a directional manner.

[0061] The central axis 36 is vertically connected to the middle part of the inner pressure plate 5, and the upper end of the central axis 36 is fixed to the power plate 21. That is to say, when the pressing plate mechanism 2 is pressing the stamped fabric and the sun visor frame, the central axis 36 is driven to slide vertically, so that the inner pressure plate 5 can drive the rubber pressure plate 34 in the corresponding inner mounting groove 31 to slide outward through the convex edge, so that the rubber pressure plate 34 spreads the punched fabric outward, effectively eliminating the air residue between the punched fabric and the sun visor frame, and improving the subsequent hot pressing effect.

[0062] In this embodiment, the pressing plate mechanism 2 includes:

[0063] The hot pressing plate 22 is horizontally arranged below the power plate 21;

[0064] The machine base 23 is fixed in the heat sealing machine 1. A mounting plate 24 is arranged in parallel below the machine base 23 in the heat sealing machine 1. Slide rods 25 are symmetrically fixed on the mounting plate 24. The upper ends of the slide rods 25 are slidably connected to the machine base 23.

A positioning hole 28 is provided in the middle of the power plate 21 , and the upper end of the central shaft 36 is coaxially connected in the positioning hole 28 .

[0068] The rubber pressing plate 34 protrudes downward from the upper template 13, and its protruding height ranges from 8 mm to 14 mm, so that the rubber pressing plate 34 can contact the edge of the punching fabric before the upper template 13. As the upper template slides downward and contacts the punching fabric, the rubber pressing plate 34 can press and contact the punching fabric with a certain pressure so as to subsequently extend it.

[0069] In this embodiment, the spring stiffness of the spring telescopic rod 37 is smaller than the spring stiffness of the lifting spring 51, so that when the center shaft 36 is driven downward, the spring telescopic rod 37 on the rubber pressure plate 34 can be compressed before the lifting spring 51. That is to say, when the rubber pressure plate 34 is pressed and contacted with the surface of the punched fabric with a certain pressure, the inner pressure plate 5 is continuously pressed downward, and its corresponding convex edge pushes the corresponding side guide block to slide, so that the rubber pressure plate 34 spreads the punched fabric outward, and when the lifting spring 51 is fully compressed, the hot pressing plate 22 in the pressing plate mechanism 2 is continuously pressed downward with the center shaft 36 to complete the thermal synthesis of the punched fabric and the sun visor frame.

[0070] In this embodiment, the control unit 4 includes:

[0071] A special-shaped frame 41, vertically fixed on the slide block 33;

[0072] A sliding sleeve 42 is vertically slidably connected to the special-shaped frame 41, and the side guide block 35 is fixed to the sliding sleeve 42;

[0073] An outer lining plate 43 is rotatably connected to the special-shaped frame 41, a straight guide groove 44 is provided in the outer lining plate 43, a pin shaft 45 is vertically fixed on the sliding sleeve 42, and the pin shaft 45 is slidably connected to the straight guide groove 44;

[0074] The electric telescopic rod 46 is rotatably connected to the special-shaped frame 41 , and the telescopic end of the electric telescopic rod 46 is hinged to the outer lining plate 43 .

[0075] In this embodiment, the electric telescopic rod 46 drives the sliding sleeve 42 to slide up and down along the special-shaped frame 41 through the straight guide groove 44 on the outer lining plate 43 under telescopic adjustment; thereby, the effective spacing between the side guide block and the convex edge on the sliding sleeve 42 can be effectively adjusted, so as to adjust the sliding displacement of the side guide block, and realize the fine adjustment control of the sliding amount of the rubber pressing plate 34, so that the rubber pressing plate 34 can be extended according to the specifications and materials of the punching fabric;

[0076] An inner spring 61 is laterally connected to the track frame 32, one end of the inner spring 61 is connected to the slider 33, and a limit block 6 is also fixed to the track frame 32, the limit block 6 abuts against a side of the slider 33 away from the inner spring 61, so that each slider 33 can always abut against the limit block 6 at the initial position under the elastic force of the inner spring 61.

[0077] As a preferred embodiment, each of the control units 4 effectively fine-controls the horizontal displacement sliding amount of the rubber pressure plate 34 according to the material, specification and ductility characteristics of the punched fabric, so that the punched fabric can be fully spread before the heat-coating operation with the sun visor frame, realizing personalized and refined processing methods, ensuring that each fabric can obtain the most suitable pretreatment, and improving the adaptation accuracy of the finished product; at the same time, automatic adjustment reduces the influence of human factors, and even in the face of subtle changes in fabric properties between batches, it can maintain the consistency and stability of the finished product quality, thereby enhancing the overall quality of the product.

[0078] In this embodiment, a heating mechanism is provided in the hot pressing plate 22 .

[0081] S2. Fine-tune the stretching process, combine with detailed analysis of the material, thickness, density, texture direction and stretching characteristics of the punching fabric, customize the hardness, surface texture and shape of the rubber pressing plate 34, so that the rubber pressing plate 34 can provide sufficient friction to drive the punching fabric to unfold smoothly; at the same time, the sliding sleeve 42 on the special-shaped frame 41 is adjusted up and down through each control unit 4 to adjust the initial installation height of the side guide block 35, thereby changing the sliding displacement of the rubber pressing plate 34 in each film support unit 3; ensure that the subsequent punching fabric can be evenly and fully spread on the surface of the sun visor frame, reducing quality problems caused by wrinkles or unevenness of the fabric;
