DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1-4 An automatic sound-absorbing sheet bonding device comprises a bearing assembly, an adjusting assembly and a pressing assembly. The bearing assembly comprises a bottom plate 1, bearing blocks 2, studs 3 and support tubes 4. The bottom plate 1 is provided with a plurality of groups of bearing blocks 2. The top walls of the bearing blocks 2 in the groups are flush. The bearing blocks 2 are provided with studs 3. The top walls of the studs 3 in the groups are flush. The support tubes 4 are threadedly connected with the studs 3. The outer diameter of the support tubes 4 is smaller than that of the bearing blocks 2. The bottom plate 1 is further provided with the adjusting assembly for assisting in supporting the materials. The pressing assembly comprises a back plate 5, a top plate 6, a lifter 7 and a pressing plate 8. The back plate 5 is arranged above the back side of the bottom plate 1. The top plate 6 is arranged above the front side of the back plate 5. The lifter 7 penetrates through the top plate 6 and is connected with the pressing plate 8. The pressing plate 8 is further provided with a plurality of groups of first through holes matched with the bearing blocks 2.

[0025] The bearing assembly is the basic part for placing materials such as steel back and sound-absorbing sheet. The bottom plate 1 plays a role in overall support. The plurality of groups of bearing blocks 2 arranged thereon provide a stable placing platform for the materials. The top walls of the bearing blocks 2 are flush. The top walls of the studs 3 in the groups are flush, so as to ensure that the steel back placed thereon is at the same horizontal height. The steel back and the sound-absorbing sheet are both provided with guide holes with the same outer diameter as that of the support tubes 4. The corresponding two groups of studs 3 are selected to be assembled with the support tubes 4. The top wall of the support tube 4 is higher than that of the stud 3. The bottom plate 1 provides stable support for the back plate 5. The top plate 6 provides stable support for the back plate 5. The lifter 7 is started. The lifter 7 (a hydraulic cylinder is adopted because the hydraulic cylinder has a large thrust and can meet the requirement for pressure in the process of pressing and bonding, so as to ensure that the sound-absorbing sheet and the steel back can be fully contacted and firmly bonded) penetrates through the top plate 6 and is connected with the pressing plate 8. When the lifter 7 is started, the piston of the hydraulic cylinder is extended to drive the pressing plate 8 to move stably downward along the vertical direction, so that the glue solution coated on the steel back is stably bonded with the sound-absorbing sheet.

[0026] In this embodiment, the pressing plate 8 is further provided with a buffer pad 9 below, and the buffer pad 9 is provided with a second through hole 10 penetrating the first through hole. The buffer pad 9 can not only buffer the impact force of the pressing plate 8 on the material during pressing, avoid damage to the sound-absorbing sheet and the surface of the steel back due to excessive impact force, and affect the bonding effect, but also can make the contact between the pressing plate 8 and the material more in line with the actual needs, ensure that the sound-absorbing sheet and the steel back are uniformly stressed and fully contacted during the entire pressing process, and improve the bonding quality. The second through hole 10 penetrating the first through hole is provided on the buffer pad 9, and the outer diameter of the first through hole and the second through hole 10 is larger than the outer diameter of the bearing block 2, so that the pressing plate 8 can be stably fed downward.

[0027] In actual use, the pressing plate 8 is further provided with a guide rod 16 penetrating the top plate 6, to ensure the stability of the lifting of the pressing plate 8.

[0028] In actual use, the adjusting assembly includes a reversible screw 11, a motor 12, a sliding block 13, a moving plate 14 in the shape of a Chinese character and a support block 15. The bottom plate 1 is further provided with a sliding groove with an upper opening, the bearing block 2 is arranged on the periphery of the sliding groove, the reversible screw 11 and two sets of symmetrically arranged sliding blocks 13 are further arranged in the sliding groove, the output end of the motor 12 penetrates the bottom plate 1 and is connected with the reversible screw 11, the sliding blocks 13 are threadedly connected with the reversible screw 11, the moving plate 14 with a side opening towards the center of the sliding groove is further arranged on the sliding blocks 13, the two free ends of the moving plate 14 are arranged on the periphery of the bearing block 2, and the support block 15 with a top wall flush with the top wall of the stud 3 is further arranged above the two free ends of the moving plate 14. The adjusting assembly is mainly used to expand the support area and ensure the stability of the material during the bonding process. When the motor 12 is started, the motor 12 drives the reversible screw 11 to rotate around its axis, and according to the screw transmission principle, the two sets of symmetrically arranged sliding blocks 13 threadedly connected with the reversible screw 11 will move towards or away from each other in the sliding groove. The moving plate 14 with a side opening towards the center of the sliding groove is installed on the sliding blocks 13, and the moving plate 14 will move synchronously with the sliding blocks 13. The two free ends of the moving plate 14 are arranged on the periphery of the bearing block 2, and the support block 15 with a top wall flush with the top wall of the stud 3 arranged above the two free ends of the moving plate 14 will also move to the corresponding position. According to the requirements, for example, when it is necessary to bond a steel back or a sound-absorbing sheet with a larger size, the original support range of the bearing block 2 is not enough. By operating the motor 12, the sliding blocks 13 drive the moving plate 14 to move away from each other, and the support block 15 is extended to the outside of the bearing block 2, thereby expanding the overall support area, so that the steel back and the sound-absorbing sheet can be placed more stably on the support structure, avoiding shaking and warping during the bonding process due to insufficient local support, ensuring that the two can be stably attached and ensuring the bonding quality. If the bottom wall of the steel back is a special-shaped structure and the studs 3 at other positions cannot provide stable support, a support plate can be sleeved on the support block 15 for stable loading of the steel back.

[0029] The corresponding two sets of bearing blocks 2, studs 3 and support blocks 15 can be used to position one gauge of steel back and sound deadening sheeting.
