DETAILED DESCRIPTION

[0032] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , a handheld flat or curved product laminating device is provided, comprising a first support part 1 and a second support part 2, one end of the first support part 1 is hinged to one end of the second support part 2 through a rotating shaft, an elastic element 3 is connected between the first support part 1 and the second support part 2; the other end of the first support part 1 is connected to a pressing roller 4 through a bearing, a first fixing frame 5 is connected between the first support parts 1, and a handheld handle 6 is connected to the middle of the first fixing frame 5; a second fixing frame 7 is connected between the second support parts 2;

[0034] A clamping block 8 is provided at the end of the first support portion 1, and the clamping block 8 forms a limiting groove 9. A through opening 10 is formed at the center of the second support portion 2. One end of the first support portion 1 passes through the through opening 10 and is hinged to the second support portion 2 in the area of ​​the limiting groove 9 via a rotating shaft. The clamping block 8 limits the opening and closing angle between the first support portion 1 and the second support portion 2 to 90°~120°.

[0035] Specifically, the first support part 1 is two brackets parallel to each other, and the pressure roller 4 is connected to the end of the bracket through a bearing; the second support part 2 is two support columns parallel to each other, and a through hole 10 is formed in the center of the support column. One end of the bracket passes through the through hole 10 and is hinged to the support column in the area of ​​the limit groove 9 through a rotating shaft, and the hinged part is limited to the section of the limit groove 9, so as to realize that when the first support part 1 and the second support part 2 rotate relative to each other, the opening and closing angle between the first support part 1 and the second support part 2 is limited to 90°~120° by the block 8.

[0036] Specifically, the width of the block 8 is greater than the width of the through opening 10 to prevent the block 8 from sliding through the through opening 10 and ensure that it can play a limiting role.

[0037] Specifically, the bottom of the second support portion 2 is connected with a roller 11. The design of the roller 11 facilitates the movement on the laminating platform when the laminating is pushed by the hand-held handle 6, thereby saving the laminating thrust.

[0038] Specifically, the clamping block 8 includes a left clamping member 12 and a right clamping member 13, and the limiting groove 9 is formed between the left clamping member 12 and the right clamping member 13; the left clamping member 12 is attached to the side of the second support portion 2 to limit the opening and closing angle between the first support portion 1 and the second support portion 2 to be less than 90°. A gap 14 is provided between the right clamping member 13 and the side of the second support portion 2, and the right clamping member 13 limits the opening and closing angle between the first support portion 1 and the second support portion 2 to be greater than 120°. Since the left clamping member 12 is attached to the side of the second support portion 2, the second support portion 2 is blocked from rotating toward the left clamping member 12, that is, the minimum opening and closing angle between the first support portion 1 and the second support portion 2 is ensured to be 90°. At the same time, since the right clamping member 13 is provided with a gap 14 between the side of the second support portion 2, the second support portion 2 can rotate toward the right clamping member 13, but when it rotates to 120°, it is blocked by the right clamping member 13, so as to prevent the opening and closing angle between the first support portion 1 and the second support portion 2 from exceeding 120°.

[0039] Specifically, the distance of the gap 14 can be determined by the angular geometric relationship. Under the technical inspiration of the present technical solution, a person skilled in the art can also determine the size of the gap 14 through a limited number of tests to ensure that the opening and closing angle between the first support part 1 and the second support part 2 does not exceed 120°.

[0040] Specifically, the elastic element 3 is a spring, and the connection position of the elastic element 3 on the first support part 1 is between the first fixing frame 5 and the rotating shaft; the connection position of the elastic element 3 on the second support part 2 is between the second fixing frame 7 and the rotating shaft. The elastic element 3 is connected between the first support part 1 and the second support part 2. When a force is applied to the hand-held handle 6, the elastic element 3 can balance the force applied to the hand-held handle 6, so that the second support part 2 rotates smoothly around the first support part 1, which helps the stability of the fit and achieves the best fit effect.

[0041] In one embodiment of the handheld flat or curved product laminating device, the pressing roller 4 includes a rubber layer 15, a metal core 16 and a roller neck 17; the rubber layer 15 is wrapped around the surface of the metal core 16, and the metal core 16 is connected to the bearing at the end of the bracket through the roller neck 17. The rubber layer 15 is made of silicone; the rubber layer 15 has good heat resistance, elasticity, and separation, and avoids deformation and adhesion during the laminating process.

[0042] In one embodiment of the handheld flat or curved product laminating device, the first fixing frame 5 is connected to a position between 1 / 3 and 2 / 3 of the length of the first support portion 1; the second fixing frame 7 is connected to a position between 1 / 3 and 2 / 3 of the length of the second support portion 2. Thus, the center of gravity of the entire laminating device is close to the geometric center, which is convenient for operation and placement.

[0043] In one embodiment of the handheld flat or curved product laminating device, the bracket of the first support part 1 is made of stainless steel, aluminum alloy or bakelite to ensure the strength of the bracket of the first support part 1 and prevent it from being deformed.

[0044] See also Figure 5 and Figure 6 The present invention also provides a handheld flat or curved product lamination method, comprising the following steps:

[0045] S1: placing the handheld flat or curved product laminating device in the embodiment on a laminating platform, buckling the first support part 1 and the second support part 2 on the laminating platform; adjusting the position of the handheld flat or curved product laminating device, and determining the laminating direction and laminating distance;

[0046] S2: placing the first layer of material to be bonded on the bonding platform, with one end of the first layer of material located at the pressure roller 4 of the first support part 1, adjusting the starting position of bonding, and fixing the first layer of material;

[0047] S3: placing the second layer of material to be laminated on the first layer of material, adjusting the starting position of the lamination, and fixing the second layer of material;

[0048] S4: Press the hand on the hand-held handle 6 and apply a pushing force along the bonding direction to complete the bonding of the first layer of material and the second layer of material.

[0049] In the technical solution of the present invention, one end of the first support part 1 is hinged to one end of the second support part 2 through a rotating shaft, and an elastic element 3 is connected between the first support part 1 and the second support part 2; the other end of the first support part 1 is connected to a pressure roller 4 through a bearing, a first fixed frame 5 is connected between the first support parts 1, and a hand-held handle 6 is connected to the middle of the first fixed frame 5; a second fixed frame 7 is connected between the second support parts 2; a clamping block 8 is provided at the end of the first support part 1, and the clamping block 8 forms a limiting groove 9, and a through opening 10 is formed in the center of the second support part 2, one end of the first support part 1 passes through the through opening 10 and is hinged to the second support part 2 in the area of ​​the limiting groove 9 through a rotating shaft, and the clamping block 8 limits the opening and closing angle between the first support part 1 and the second support part 2 to 90°~120°. Since the left clamp 12 is in contact with the side of the second support part 2, the second support part 2 is blocked from rotating toward the left clamp 12, which ensures that the opening and closing angle between the first support part 1 and the second support part 2 is at least 90°. At the same time, since a gap 14 is provided between the right clamp 13 and the side of the second support part 2, the second support part 2 can rotate toward the right clamp 13, but when it rotates to 120°, it is blocked by the right clamp 13, which prevents the opening and closing angle between the first support part 1 and the second support part 2 from exceeding 120°. The elastic element 3 is connected between the first support part 1 and the second support part 2. When a force is applied to the hand-held handle 6, the elastic element 3 can balance the force applied to the hand-held handle 6, so that the second support part 2 rotates smoothly around the first support part 1, which helps the stability of the fit and achieves the best fit effect. When in use, place the handheld flat or curved product laminating device on the laminating platform, and buckle the first support part 1 and the second support part 2 on the laminating platform; adjust the position of the handheld flat or curved product laminating device to determine the laminating direction and laminating distance; place the first layer of material to be laminated on the laminating platform, with one end of the first layer of material located at the pressure roller 4 of the first support part 1, adjust the starting position of laminating, and fix the first layer of material; place the second layer of material to be laminated on the first layer of material, adjust the starting position of laminating, and fix the second layer of material; press the hand on the handheld handle 6, apply thrust along the laminating direction, and complete the laminating of the first layer of material and the second layer of material. The present invention can realize the laminating of flat products and curved products with a certain curvature, especially involving the laminating of Film and Film (soft to soft), and the laminating of Film and Cover Glass (soft to hard). The present invention is flexible to use, simple to operate, and has low equipment investment cost and production cost, and realizes low-cost laminating operations for medium and large-sized products.

[0050] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
