Description

Technical Field

[0001] This utility model belongs to the technical field of LED strip dispensing equipment, and in particular relates to a high-efficiency LED strip dispensing device for display screens. Background Technology

[0002] The display screen is formed by assembling several groups of light strips on a base plate. During the assembly of the display screen, glue needs to be applied evenly to the back of each light strip before the light strips are installed one by one on the base plate, and the light strips are connected to the base plate by circuitry. However, when applying glue to the back of each light strip manually, the glue is not applied evenly, which can easily cause glue to spill and adhere to other parts of the light strip, making the light strip easy to stick to other objects. This is also time-consuming, labor-intensive, and inefficient. In addition, the glue usually contains volatile substances, which can easily cause respiratory diseases in the operators after evaporation, affecting their health.

[0003] To address these issues, we provide a high-efficiency LED strip dispensing device for displays to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1 to 4 This utility model discloses a high-efficiency display screen LED strip dispensing device, comprising a conveying component 1 and a dispensing component 2. The conveying component 1 includes a conveyor belt 101, an intermittent stepping drive assembly 102, and a set of LED strip placement frames 103. The dispensing component 2 includes a bracket 201 and a dispensing assembly 202. By setting the dispensing component 2 above the conveying component 1, the LED strips are placed above the LED strip placement frames 103 in the conveying component 1. The dispensing assembly 202 in the dispensing component 2 automatically applies glue to the LED strips below, eliminating manual operation and avoiding the impact of glue evaporation on the workpiece. While improving the accuracy of dispensing and preventing glue overflow, the LED strip placement frame 103 is placed on the conveyor belt 101 of the conveying component 1. The conveyor belt 101 is driven by the intermittent stepping drive component 102. The dispensing component 202 is set on the bracket 201, which is located at the upper end of the conveyor belt 101. The conveyor belt 101 is pushed forward intermittently, so that the dispensing component 202 dispenses glue to the LED strips above the conveyor belt 101 in batches, and then pushes the LED strips forward after dispensing, thereby achieving the technical effect of improving dispensing efficiency.

[0028] Specifically, the intermittent stepping drive assembly 102 is located below the conveyor belt 101 and is connected to the rotating shaft of the conveyor belt 101 via a transmission. The light strip placement frame 103 is arranged in an array along the length of the conveyor belt 101 at the upper end of the conveyor belt 101. The bracket 201 is a U-shaped structure with the opening facing downwards. The lower inner sides of the vertical plates on both sides of the bracket 201 are fixedly installed on the outer sides of both sides of the conveyor belt 101. The glue injection assembly 202 is located at the lower end of the bracket 201.

[0029] Furthermore, the glue dispensing assembly 202 includes a set of glue guns 202a, a glue gun sleeve 202b, and a cylinder 202c. The cylinder 202c is fixedly mounted on the outside of the bracket 201, and the telescopic end of the cylinder 202c passes through the bracket 201. One side of the glue gun sleeve 202b is fixedly mounted on the telescopic end of the cylinder 202c. The glue gun sleeve 202b is a plate-shaped structure with its length parallel to the length direction of the conveyor belt 101. A set of mounting holes 202b-1 are vertically arrayed along the length direction of the glue gun sleeve 202b. The set of glue guns 202a are respectively installed on each mounting hole 202b-1. Inside the mounting hole 202b-1, the cylinder 202c pushes the glue gun sleeve 202b to the other side of the conveyor belt 101, so that the glue gun 202a passes over the top of the light strip at the top of the conveyor belt 101 and applies glue to the light strip. After the glue application is completed, the conveyor belt 101 moves forward, pushing the light strips with glue applied below the bracket 201 forward, and conveying the light strips that have not yet been glued to the bottom of the bracket 201. The cylinder 202c then pulls the glue gun sleeve 202b back, so that the glue gun sleeve 202b passes over the new batch of light strips and applies glue to that batch of light strips.

[0030] Furthermore, the glue gun 202a includes a glue gun barrel 202a-1, a glue gun head 202a-2, and a glue injection piston 202a-3. The glue gun barrel 202a-1 is fixedly sleeved in the mounting hole 202b-1, the glue gun head 202a-2 is sleeved on the lower end of the glue gun barrel 202a-1, and the glue injection piston 202a-3 is slidably sleeved in the glue gun barrel 202a-1 and passes through the upper end of the glue gun barrel 202a-1.

[0031] Furthermore, an end cap 202a-4 is fixedly provided on the upper end of the glue injection piston column 202a-3, and a return spring 202a-5 is sleeved on the outer side of the glue injection piston column 202a-3. The lower end of the return spring 202a-5 abuts against the upper end face of the glue gun barrel 202a-1, and the upper end of the return spring 202a-5 abuts against the lower top surface of the end cap 202a-4. A lower pressure plate 202a-6 is fixedly sleeved on the upper end of the glue injection piston columns 202a-3 of the glue gun 202a assembly. The lower pressure plate 202a-6 is a U-shaped opening with the opening facing upward. The molded plate structure has a rotating roller 202a-7 rotatably mounted between the two vertical plates on the upper end of the lower pressure plate 202a-6. Semi-cylindrical grooves 201a are respectively opened at both ends of the lower frame surface of the bracket 201 near the two vertical plates. The rotating roller 202a-7 fits against the lower frame surface of the bracket 201. When the cylinder 202c pulls the glue gun sleeve 202b to one end face below the bracket 201, the return spring 202a-5 pushes the end cap edge 202a-4 upwards, causing the lower pressure plate 202a above the glue gun 202a assembly to... -6 rises accordingly, causing the rotating roller 202a-7 at the upper end of the lower pressure plate 202a-6 to push into the semi-cylindrical groove 201a, thereby stopping the glue injection piston 202a-3 from injecting glue. When the cylinder 202c pushes the glue gun sleeve 202b to move and pass the light strip above the conveyor belt 101, the rotating roller 202a-7 at the upper end of the lower pressure plate 202a-6 disengages from the semi-cylindrical groove 201a and presses against the lower frame surface of the bracket 201, thereby causing the lower pressure plate 202a-6 to press the glue injection piston 202a-3 downward. 3. The lower end of the glue injection piston 202a-6 moves downward inside the glue gun barrel 202a-1, and squeezes the glue in the glue gun barrel 202a-1 from the glue gun head 202a-2 onto the light strip below. When the cylinder 202c pushes the glue gun sleeve 202b to the other side of the bracket 201, the rotating roller 202a-7 is pushed into the semi-cylindrical groove 201a under the pressure of the return spring 202a-5, and at the same time, the glue injection piston 202a-3 moves upward inside the glue gun barrel 202a-1, thereby stopping the glue injection.

[0032] Furthermore, guide lugs 201b are fixedly provided on the upper two sides of each side plate of the bracket 201, and a guide post 201b-1 is fixedly provided between the guide lugs 201b on each side of the bracket 201. Sliding lugs 202a-8 are fixedly provided on the outer sides of the vertical plates on both sides of the lower pressure plate 202a-6. The two sliding lugs 202a-8 are slidably sleeved on the outer sides of the two guide posts 201b-1, so that the reciprocating motion of the glue gun sleeve 202b under the bracket 201 remains stable.

[0033] The operation process in this embodiment is as follows:

[0034] Place the light strips to be glued on the light strip placement frame 103, and arrange the light strip placement frames 103 on the upper end of the conveyor belt 101. The conveyor belt 101 transports the light strip placement frames 103 to the lower part of the bracket 201. The cylinder 202c pushes the glue gun sleeve 202b to the other side of the conveyor belt 101. At this time, the rotating roller 202a-7 at the upper end of the lower pressure plate 202a-6 disengages from the semi-cylindrical groove 201a and presses against the lower frame surface of the bracket 201, thereby causing the lower pressure plate 202a-6 to press down on the glue injection piston column 202a-3. The lower end of the glue injection piston column 202a-6 moves downward in the glue gun barrel 202a-1, and squeezes the glue in the glue gun barrel 202a-1 from the glue gun head 202a-2 onto the light strip below, so that the glue gun 2... As 02a passes over the top of the light strip on the upper end of the conveyor belt 101, it applies glue to the light strip. When the cylinder 202c pushes the glue gun sleeve 202b to the other side of the bracket 201, the rotating roller 202a-7 is pushed into the semi-cylindrical groove 201a under the pressure of the return spring 202a-5. At the same time, the glue injection piston column 202a-3 moves upward in the glue gun barrel 202a-1, thereby stopping the glue injection. After the glue application is completed, the conveyor belt 101 moves forward, pushing the light strips with glue application below the bracket 201 forward, and conveying the light strips that have not been glued to the bottom of the bracket 201. The cylinder 202c then pulls the glue gun sleeve 202b back, so that the glue gun sleeve 202b passes over the new batch of light strips, and applies glue to the new batch of light strips.

[0035] Example 2

[0036] Please see Figures 1 to 5 Based on Embodiment 1, the intermittent stepping drive assembly 102 includes a drive motor 102a, an intermittent gear 102b, and a full gear 102c. The drive motor 102a drives the intermittent gear 102b to rotate, and the intermittent gear 102b intermittently drives the full gear 102c to rotate, so that the full gear 102c drives the conveyor belt 101 to intermittently convey motion.

[0037] Specifically, drive motor 102a is installed at the lower end of conveyor belt 101, intermittent gear 102b is fixedly sleeved on the output shaft of drive motor 102a, and full gear 102c is rotatably installed on the side of conveyor belt 101 and meshes with intermittent gear 102b. The rotating shaft of full gear 102c is connected to the rotating shaft of conveyor belt 101 via a sleeve belt.

[0038] Furthermore, a glue injection cylinder 203 is fixedly installed on the upper end of the bracket 201, and each discharge end of the glue injection cylinder 203 is connected to the glue gun cylinder 202a-1 on each glue gun 202a through a hose.

[0039] The operation process in this embodiment is as follows:

[0040] The drive motor 102a drives the intermittent gear 102b to rotate, causing the intermittent gear 102b to intermittently drive the full gear 102c to rotate. This causes the full gear 102c to drive the conveyor belt 101 to move intermittently. When the cylinder 202c pushes the glue gun sleeve 202b to move, causing the glue gun 202a to dispense glue, the tooth surface of the intermittent gear 102b does not mesh with the tooth surface of the full gear 102c, causing the full gear 102c to stop rotating, thus stopping the conveyor belt 101. When the cylinder 202c pushes the glue gun sleeve 202b to one side of the bracket 201, the tooth surface of the intermittent gear 102b meshes with the tooth surface of the full gear 102c, causing the full gear 102c to drive the conveyor belt 101 forward, pushing the light strips that have been dispensed forward and conveying the light strips that have not been dispensed to the bottom of the bracket 201.
