Description

Technical Field

[0001] The present invention relates to the technical field of light guide plate assembly, and in particular to an assembly and pressing device for light guide plates. Background Art

[0002] A glass light guide plate (LGP) is a glass plate with light-guiding dots printed on the back using laser engraving, V-shaped cross-grid engraving, or UV screen printing. Light enters the LGP from the end face and diffuses at various angles upon reaching each light-guiding dot, breaking the reflective conditions and exiting through the front face. Fully laminated glass LGPs are connected to other structures using adhesive layers such as 3M adhesive.

[0003] The general pressing operation of the existing light guide plate and other structures is completed by a pressing device. For relatively complex pressing structures, complex manual alignment operations are required before the pressing operation can be carried out. The processing efficiency is low, the workload of the operators is high, and the reliability of the alignment accuracy is low. The pressing efficiency is low during pressing. If dust or particles fall on the glass light guide plate during the pressing process, defective products will be produced, which will cause certain losses to production.

[0004] In the patent document with the announcement number CN114919195A4, an assembly and pressing device for automobile light guide plates is disclosed. Through the setting of a positioning device, the structure to be assembled is driven to move in a small range so that it is in the best position with the pressing device above, thereby improving work efficiency and work quality. Through the setting of the pressing device, pressing adjustment is performed for different types of light guide plates. Under the action of each pressing component, multi-angle fitting is performed according to the surface curvature of the light guide plate. The pressing force is buffered and coordinated to ensure the pressing quality of the product.

[0005] However, when the assembly and pressing device for automobile light guide plates is used, the pressing force cannot be fine-tuned during pressing. Different pressing forces may cause the light guide plates to be damaged or not pressed properly, resulting in a decrease in the production quality of the light guide plates. Therefore, it is necessary to propose an assembly and pressing device for light guide plates. Summary of the Invention

[0006] The object of the present invention is to provide an assembly and pressing device for a light guide plate to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: an assembly and pressing device for a light guide plate, comprising a workbench and a support frame arranged on the top of the workbench, a fixed buffer device being arranged inside the workbench, and a pressing mechanism being arranged at the bottom of the support frame;

The left mounting plate and the right mounting plate are fixedly connected to the left and right sides of the workbench respectively. The positioning rod is fixedly connected to the inner wall of the left mounting plate. The screw rod is rotatably connected to the inner wall of the right mounting plate. The roller is arranged at the bottom of the support frame. The roller can reduce the friction force when the support frame moves and can also support the support frame. The motor is arranged on one side of the right mounting plate, the mounting frame is arranged at the bottom of the support frame, the pressing roller is rotatably connected to one side of the mounting frame, the guide rod is fixedly connected to the top of the mounting frame, the threaded rod is rotatably connected to the top of the mounting frame, and the handle is fixedly connected to the top of the threaded rod.

[0012] Preferably, a tripod is fixedly connected to the bottom of the workbench, and four tripods are evenly distributed on the bottom of the workbench.

[0013] Preferably, the outer surface of the laminating roller is provided with felt, which can protect the outer surface of the light guide plate during laminating on the one hand, and absorb some dust particles on the surface of the light guide plate during laminating on the other hand.

[0014] Preferably, the top of the support frame is provided with two through holes cooperating with the guide rod and one threaded hole cooperating with the threaded rod, and one side of the support frame is provided with a through hole cooperating with the positioning rod and one threaded hole cooperating with the screw rod. When the threaded rod rotates, the mounting frame moves linearly in the direction of the threaded rod, and when the screw rod rotates, the support frame moves linearly in the direction of the screw rod.

[0015] Preferably, one side of the connecting rod is fixedly connected to one side of the square support plate, and the other side is fixedly connected to one side of the T-shaped plate. There are eight connecting rods evenly distributed around the square support plate. When the square support plate is pressed down, it will drive the T-shaped plate to move downward.

[0016] Preferably, a rubber pad is provided at the bottom of the square support plate, which can play a buffering role during pressing. The square support plate does not contact the bottom of the inner wall of the workbench in a natural state.

[0017] Preferably, two through holes cooperating with the connecting rod are formed on one side of the splint, and the splint can move in the direction of the connecting rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The assembly and pressing device for the light guide plate adjusts the position of the surrounding clamps through the provided fixing mechanism, so that the clamps compress the reset springs, and the structure to be assembled is placed between the surrounding clamps. The clamps are then released, and the compressed reset springs will generate a rebound force under the action of their own restoring force. The rebound force acts on one side of the clamps, so that the surrounding clamps clamp the structure to be assembled, thereby completing the fixation of the structure to be assembled. The device is suitable for accessories of different specifications and has a wide range of applications.

[0020] 2. The assembly and pressing device for the light guide plate, through the provided buffer mechanism, will apply pressure to the square support plate under the action of the gravity of the structure to be assembled after the structure to be assembled is fixed. At this time, the T-shaped plate fixed at one end of the connecting rod will apply pressure to the buffer spring. At this time, the position of the entire square support plate moves downward, and the buffer spring is in a compressed state. On the one hand, it can provide sufficient buffer space during pressing to avoid damage to the light guide plate when the pressing force is large. On the other hand, it can cooperate with the pressing roller to adjust the pressing force.

[0021] 3. The assembly and pressing device for the light guide plate uses a pressing mechanism to rotate the handle and then the threaded rod, so that the mounting frame makes a linear motion in the direction of the threaded rod, and adjusts the position of the pressing roller until the outer surface of the pressing roller is close to the horizontal height of the top of the light guide plate to be assembled. The pressing force required in actual work can be adjusted according to the height of the pressing roller. After starting the motor, the screw rod rotates accordingly, and the roller shows a linear motion in the direction of the screw rod, so that the pressing roller rolls and presses on the surface of the light guide plate to be assembled. The pressing roller can also adsorb dust particles on the surface of the light guide plate during pressing, and the pressing force can be gradually adjusted by adjusting the height of the pressing roller during pressing. The pressing roller can also make a linear reciprocating motion by the forward and reverse rotation of the motor to repeatedly press the light guide plate to ensure the pressing quality.

Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0031] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] See also Figures 1-6 , the present invention provides a technical solution:

[0033] Example 1:

[0034] An assembly and pressing device for a light guide plate comprises a workbench 1 and a support frame 2 arranged on the top of the workbench 1, wherein a fixed buffer device is arranged inside the workbench 1;

[0035] The fixed buffer device includes a fixing mechanism and a buffer mechanism;

[0036] The fixing mechanism is located inside the workbench 1 and includes a square support plate 101, a connecting rod 102, a clamping plate 103, a return spring 104, and a spring washer 105. The square support plate 101 is arranged inside the workbench 1. A rubber pad is provided at the bottom of the square support plate 101. The rubber pad can act as a buffer when pressing. The square support plate 101 does not contact the bottom of the inner wall of the workbench 1 in its natural state. The connecting rod 102 is fixedly connected to one side of the square support plate 101. One side of the connecting rod 102 is fixedly connected to one side of the square support plate 101, and the other side is fixedly connected to one side of the T-shaped plate 106. There are eight connecting rods 102 evenly distributed around the square support plate 101. When the square support plate 101 is pressed down, it will drive the T-shaped plate 106 to move downward. The clamping plate 103 is movably connected to one side of the square support plate 101. Two through holes are opened on one side of the clamping plate 103 to cooperate with the connecting rod 102. The clamping plate 103 can move in the direction of the connecting rod 102. The return spring 104 is movably connected to the outside of the connecting rod 102, and the spring washer 105 is provided on one side of the connecting rod 102. The positions of the surrounding clamping plates 103 are adjusted so that the clamping plates 103 compress the return spring 104. The structure to be assembled is placed between the surrounding clamping plates 103. The clamping plates 103 are then released. At this time, the compressed return spring 104 generates a rebound force under the action of its own restoring force. The rebound force acts on one side of the clamping plates 103, causing the surrounding clamping plates 103 to clamp the structure to be assembled, thus completing the fixation of the structure to be assembled.

[0037] Example 2:

[0038] Based on the first embodiment, the buffer mechanism is located on one side of the inner wall of the workbench 1. The buffer mechanism includes a T-shaped plate 106, a T-shaped slot 107, a telescopic rod 108, a buffer spring 109, and a damping plate 110. The T-shaped slot 107 is opened on one side of the inner wall of the workbench 1, the T-shaped plate 106 is slidably connected to the inner wall of the T-shaped slot 107, the telescopic rod 108 is fixedly connected to the bottom of the T-shaped plate 106, the buffer spring 109 is movably connected to the outside of the telescopic rod 108, and the damping plate 110 is set at the bottom of the telescopic rod 108. After the structure to be assembled is fixed, the weight of the structure to be assembled will apply pressure to the square support plate 101. The T-shaped plate 106 fixed at one end of the connecting rod 102 will apply pressure to the buffer spring 109, causing the entire square support plate 101 to move downward and the buffer spring 109 to be in a compressed state.

[0039] Example 3:

[0040] On the basis of Example 2, a pressing mechanism is provided at the bottom of the support frame 2, and the pressing mechanism includes a left mounting plate 201, a right mounting plate 202, a positioning rod 203, a screw rod 204, a roller 205, a motor 206, a mounting frame 207, a pressing roller 208, a guide rod 209, a threaded rod 210 and a handle 211. The left mounting plate 201 and the right mounting plate 202 are respectively fixedly connected to the left and right sides of the workbench 1, the positioning rod 203 is fixedly connected to the inner wall of the left mounting plate 201, the screw rod 204 is rotatably connected to the inner wall of the right mounting plate 202, and the roller 205 is provided at the bottom of the support frame 2. The roller 205 can reduce the friction when the support frame 2 moves, and can also support the support frame 2. The motor 206 is mounted on one side of the right mounting plate 202, the mounting frame 207 is mounted on the bottom of the support frame 2, and the pressing roller 208 is rotatably connected to one side of the mounting frame 207. The outer surface of the pressing roller 208 is provided with a felt. The felt can protect the outer surface of the light guide plate during pressing and absorb some dust particles on the surface of the light guide plate during pressing. The guide rod 209 is fixedly connected to the top of the mounting frame 207, the threaded rod 210 is rotatably connected to the top of the mounting frame 207, and the handle 211 is fixedly connected to the top of the threaded rod 210. The top of the support frame 2 is provided with two through holes that cooperate with the guide rod 209 and a threaded hole that cooperates with the threaded rod 210. The side of the support frame 2 is provided with a through hole that cooperates with the positioning rod 203 and a threaded hole that cooperates with the screw rod 204. When the screw rod 210 rotates, the mounting frame 207 performs linear motion in the direction of the threaded rod 210. When the screw rod 204 rotates, the support frame 2 performs linear motion in the direction of the screw rod 204. Rotate the handle 211 to adjust the position of the pressing roller 208 until the outer surface of the pressing roller 208 is close to the horizontal height of the top of the light guide plate to be assembled. The pressing force required in actual work can be adjusted according to the height of the pressing roller 208. After starting the motor 206, the screw 204 rotates accordingly, and the roller 205 performs a linear motion in the direction of the screw 204, so that the pressing roller 208 rolls and presses on the surface of the light guide plate to be assembled. After adjusting the height of the pressing roller 208, during the pressing process, the square support plate 101 will present different heights for different pressing forces. Correspondingly, the buffer spring 109 will be further compressed. The buffer spring 109 can provide sufficient adjustment space when adjustment is needed before pressing to avoid excessive pressing force causing damage to the light guide plate.

[0041] A tripod 3 is fixedly connected to the bottom of the workbench 1 , and four tripods 3 are evenly distributed on the bottom of the workbench 1 .

[0042] Working principle:

[0043] First, the positions of the four surrounding clamps 103 are adjusted through the provided fixing mechanism, so that the clamps 103 compress the reset springs 104, and the structure to be assembled is placed between the four surrounding clamps 103. Then the clamps 103 are released. At this time, the reset springs 104 that have been compressed by the force will generate a rebound force under the action of their own restoring force. The rebound force acts on one side of the clamps 103, so that the four surrounding clamps 103 clamp the structure to be assembled, thereby completing the fixation of the structure to be assembled.

[0044] Furthermore, through the provided buffer mechanism, after the structure to be assembled is fixed, the square support plate 101 will be pressurized by the gravity of the structure to be assembled itself. At this time, the T-shaped plate 106 fixed at one end of the connecting rod 102 will apply pressure to the buffer spring 109. At this time, the entire square support plate 101 moves downward, and the buffer spring 109 is in a compressed state.

[0045] Furthermore, after the structure to be assembled is fixed, the light guide plate to be assembled is placed on top of the structure to be assembled, and the assembly positions are matched with each other.

[0046] Furthermore, through the provided pressing mechanism, the handle 211 is rotated to rotate the threaded rod 210, so that the mounting frame 207 makes a linear motion in the direction of the threaded rod 210, and the position of the pressing roller 208 is adjusted until the outer surface of the pressing roller 208 is close to the horizontal height of the top of the light guide plate to be assembled. The pressing force required in actual work can be adjusted according to the height of the pressing roller 208. After starting the motor 206, the screw rod 204 rotates accordingly, and the roller 205 shows a linear motion in the direction of the screw rod 204, so that the pressing roller 208 rolls and presses on the surface of the light guide plate to be assembled.

[0047] Furthermore, the pressing roller 208 can perform preliminary cleaning of dust and debris on the surface of the light guide plate to be assembled during pressing, thereby improving the quality of the light guide plate.

[0048] Furthermore, after adjusting the height of the pressing roller 208, during the pressing process, the square support plate 101 will present different heights for different pressing forces, and correspondingly, the buffer spring 109 will be further compressed. The buffer spring 109 can provide sufficient adjustment space when adjustment is needed before pressing to avoid damage to the light guide plate due to excessive pressing force.
