[0028] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Figures 1 to 6 An embodiment of the laminating device of the present invention is shown. The laminating device of this embodiment includes a conveying mechanism 1, a supporting seat 2 located below the conveying mechanism 1, a laminating mechanism 3 located above the conveying mechanism 1, and a product clamp 4 installed on the conveying mechanism 1. The conveying mechanism 1 is arranged on a mounting frame 5. The mounting frame 5 is provided with a channel 51 for the supporting seat 2 to pass through. Elastic support components 6 are also provided at both ends of the mounting frame 5.

[0030] In the pressing device of this embodiment, the product to be pressed and riveted is positioned in the product fixture 4 and conveyed to between the pressing mechanism 3 and the supporting seat 2 by the conveying mechanism 1, and then the pressing mechanism 3 descends. When the pressing mechanism 3 contacts the product, under the action of its pressure, the product fixture 4, the conveying mechanism 1 and the mounting frame 5 overcome the elastic force of the elastic support component 6 and move downward, and the supporting seat 2 passes through the channel 51 on the mounting frame 5 and fits with the bottom of the product fixture 4, so that the supporting seat 2 is used to bear the riveting pressure of the overweight load to avoid damage to the conveying mechanism 1 and the mounting frame 5; after the riveting is completed, the pressing mechanism 3 rises, and under the elastic force of the elastic support component 6, the mounting frame 5, the conveying mechanism 1 and the product fixture 4 rise and reset as a whole, and finally the conveying mechanism 1 is used to convey the product fixture 4 to the downstream station without affecting the logistics transfer efficiency.

[0031] Further, in this embodiment, the elastic support assembly 6 includes a support rod 61 provided on both sides of the conveying mechanism 1 and an elastic member 62 provided on the support rod 61, the mounting frame 5 is movably sleeved on the support rod 61, and a limit portion 63 is provided on the support rod 61, the lower end of the elastic member 62 abuts against the limit portion 63, and the upper end abuts against the mounting frame 5. Preferably, the four support rods 61 are distributed in a rectangular shape, which can effectively provide floating support for the mounting frame 5. When the pressing mechanism 3 contacts the product, under the pressure of the pressing mechanism 3, the product fixture 4, the conveying mechanism 1 and the mounting frame 5 overcome the elastic force of the elastic member 62 and move downward; after the riveting is completed, the pressing mechanism 3 rises, and under the elastic force of the elastic member 62, the mounting frame 5, the conveying mechanism 1 and the product fixture 4 rise and reset as a whole. The support rod 61 can provide a guiding effect for the mounting frame 5, ensure that the lifting and lowering movement is stable and smooth, has a high movement accuracy, and has a simple and effective structure. Among them, the limit portion 63 preferably adopts an annular flange structure, which can provide a good limiting effect for the elastic member 62.

[0032] Furthermore, in this embodiment, the mounting frame 5 is provided with a first sliding sleeve 52, and the support rod 61 is inserted into the first sliding sleeve 52. The first sliding sleeve 52 can reduce the friction resistance and wear between the mounting frame 5 and the support rod 61, and the structure is reasonable and effective.

[0033] Furthermore, in this embodiment, the first sliding sleeve 52 is an inverted T-shaped structure, the end of the first sliding sleeve 52 with a smaller diameter is embedded in the mounting frame 5, and the upper end of the elastic member 62 abuts against the end of the first sliding sleeve 52 with a larger diameter. The elastic force of the elastic member 62 can be transmitted to the mounting frame 5 through the end of the first sliding sleeve 52 with a larger diameter, thereby driving the mounting frame 5 to rise and reset, and the inverted T-shaped structure can also prevent the first sliding sleeve 52 from moving relative to the mounting frame 5.

[0034] As a preferred embodiment, the elastic member 62 is a coil spring and is sleeved on the outer circumference of the support rod 61, which has a simple and reliable structure. Of course, in other embodiments, the elastic member 62 can also be elastic rubber, elastic rope, etc. Further, a locking member such as a locking nut can be set at the upper end of the support rod 61 to prevent the mounting frame 5 from falling off the support rod 61 under the elastic force of the elastic member 62.

[0035] Furthermore, in this embodiment, the mounting frame 5 includes a mounting plate 53 and conveying guide rails 54 provided on both sides of the mounting plate 53, the channel 51 is provided on the mounting plate 53, and correspondingly, the support rod 61 is also provided in the mounting plate 53, the conveying mechanism 1 includes pulleys 11 provided at both ends of the conveying guide rails 54 and a conveying belt 12 wound around the pulleys 11, and the product fixture 4 is provided on the conveying belt 12. When the pressing mechanism 3 is pressed down, the product fixture 4, the conveying mechanism 1, the conveying guide rails 54 and the mounting plate 53 are lowered as a whole; after the pressing is completed, the pulley 11 rotates to drive the conveying belt 12 to operate, and the conveying belt 12 conveys the product fixture 4 to the downstream station, and the structure is reasonable and effective.

[0036] Furthermore, in this embodiment, the pressing device also includes a conveying drive member 7 (such as a servo motor, etc.) arranged on the side of the mounting frame 5, and the conveying drive member 7 is connected to the pulley 11 at one end of the conveying guide rail 54 through a universal coupling 71. The floating connection between the conveying drive member 7 and the pulley 11 is realized through the universal coupling 71, so as to avoid damage caused by the relative displacement of the two when the pulley 11 descends, and the structure is simple and effective. When the conveyor belt 12 needs to convey the product fixture 4 to the downstream station, the conveying drive member 7 is started and drives the pulley 11 to rotate through the universal coupling 71.

[0037] Furthermore, in this embodiment, a slider 41 is provided on the product fixture 4 to cooperate with the conveying guide rail 54. The product fixture 4 cooperates with the conveying guide rail 54 through the slider 41, which can prevent the product fixture 4 from deviating on the conveyor belt 12 and improve the stability and reliability of the conveying. On the other hand, the downward pressure on the product fixture 4 can be transmitted to the conveying guide rail 54 and the mounting plate 53, thereby driving the conveyor belt 12 to descend, avoiding the excessive downward pressure being directly transmitted to the conveyor belt 12 to cause damage. The structure is reasonable and effective.

[0038] Further, in this embodiment, the pressing mechanism 3 includes a pressing head 31, a pressing head mounting seat 32 for mounting the pressing head 31, a lifting drive member 33 (such as a cylinder, an electric push rod, etc.) connected to the pressing head mounting seat 32, and a lifting guide column 34 arranged at both ends of the pressing head mounting seat 32, and a second sliding sleeve 35 is arranged at both ends of the pressing head mounting seat 32, and the lifting guide column 34 is inserted into the second sliding sleeve 35 in a one-to-one correspondence. When pressing is required, the lifting drive member 33 drives the pressing head mounting seat 32 and the pressing head 31 to descend until the lower side of the product fixture 4 is in contact with the bearing seat 2, and then the lifting drive member 33 drives the pressing head 31 to further apply downward pressure to complete the pressing and riveting of the upper and lower parts of the product. The lifting guide column 34 cooperates with the second sliding sleeve 35 to provide a guiding effect and reduce friction resistance, so as to ensure that the lifting process of the pressing head 31 is stable and smooth, and has a high motion accuracy. Preferably, the second sliding sleeve 35 adopts a T-shaped structure, and the end with a smaller diameter is embedded in the pressing head mounting seat 32.

[0039] Furthermore, in the present embodiment, the pressing device also includes a protective box 8, the conveying mechanism 1, the bearing seat 2 and the mounting frame 5 are arranged in the protective box 8, the lower end of the pressing mechanism 3 extends into the protective box 8, and the protective box 8 is provided with a protective box door 81 at both ends of the conveying mechanism 1. When the product may be harmful or dangerous during the pressing process, the protective box door 81 remains closed, so that the pressing can be carried out in a closed environment to avoid damage to the operators and the factory environment. When the product fixture 4 needs to enter and exit the protective box 8, the corresponding protective box door 81 can be opened. Preferably, the protective box door 81 adopts a lifting structure, and is driven to rise and fall by a cylinder, an electric push rod, etc., which can make full use of the vertical space in the protective box 8, making the protective box 8 more compact.
