[0002] A dispensing machine, also known as a glue coating machine, a drop glue machine, a glue applying machine, a potting machine, etc., is specialized for controlling fluids. It is an automatic machine that drops and coats fluids on the surface or inside of products.

[0003] In the existing dispensing equipment during the processing process, the movement of the dispensing head is basically controlled by manual dispensing to perform dispensing on the LED board. However, usually during the dispensing process, due to the instability of manual dispensing by humans, excess glue will adhere to the LED board during the processing. If the excess glue is not removed in time, it will affect the quality of the LED board when leaving the factory. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a dispensing equipment to solve the technical problem that during the dispensing process, due to the instability of manual dispensing by humans, excess glue will adhere to the LED board during the processing. If the excess glue is not removed in time, it will affect the quality of the LED board when leaving the factory.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A dispensing equipment, including a workbench, on which a work plate for placing an LED board is slidably installed. On both side walls at the two ends of the workbench, a first long strip-shaped groove is respectively opened, and the two first long strip-shaped grooves are parallel to each other. A sliding frame is slidably installed on the two first long strip-shaped grooves. Two first cylinders are installed on the sliding frame. The telescopic ends of the two first cylinders vertically penetrate through the sliding frame, and a horizontal flat plate is installed on the telescopic ends of the two first cylinders. A first translation assembly is installed on the flat plate. A dispensing assembly vertically facing the work plate is fixedly provided on the first translation assembly. A glue scraping assembly is also provided on the first translation assembly and is located on one side of the dispensing assembly. The glue scraping assembly includes a third cylinder, an L-shaped scraping plate, and a glue collecting plate. The third cylinder is fixedly installed on the first translation assembly. The scraping plate is fixedly installed on the telescopic end of the third cylinder. The glue collecting plate is fixedly installed at the bottom of the first translation assembly and abuts against the scraping plate when it rotates.

[0007] Working Principle:

[0008] When it is necessary to process the glue that overflows during the dispensing process, first, the operator places the LED board on the working board. Then, the operator starts the two first cylinders, and the two first cylinders drive the flat plate to move vertically. The flat plate drives the first translation assembly to move vertically. Then, the operator starts the first translation assembly, and the first translation assembly drives the dispensing assembly to move. Then, the operator starts the dispensing assembly to perform a dispensing operation on the LED board placed on the working board. When there is excess glue overflowing from the LED board, at this time, the operator can start the third cylinder, and the telescopic end of the third cylinder drives the scraper to move horizontally until the scraper is translated to one side of the glue receiving plate and abuts against the glue receiving plate.

[0009] The beneficial effects of the present utility model are as follows:

[0010] Compared with the prior art, during the dispensing process of the dispensing assembly, the operator only needs to drive the scraper to move horizontally through the telescopic end of the third cylinder until the scraper is translated to one side of the glue receiving plate and abuts against the glue receiving plate. In this way, the excess overflowing glue can be processed, preventing the factory quality of the LED board from being affected due to the failure to remove the glue in time.

The glue scraping assembly includes a third cylinder 7, an L-shaped scraping plate 9, and a glue collecting plate 10. The third cylinder 7 is fixedly mounted on the first translation assembly. The scraping plate 9 is fixedly mounted on the telescopic end of the third cylinder 7. The glue collecting plate 10 is fixedly mounted on the bottom of the first translation assembly and abuts against the scraping plate 9 when the scraping plate 9 rotates. One end of the glue collecting plate 10 that abuts against the scraping plate 9 is processed with an oblique angle, and the width of the glue collecting plate 10 is equal to that of the scraping plate 9. It also includes four retaining edges 11. The four retaining edges 11 are divided into two groups, and each group of retaining edges 11 is divided into two pieces and is respectively fixedly mounted at both ends of the glue collecting plate 10 and both ends of the scraping plate 9. The working width of the scraping plate 9 when scraping glue on the LED board is equal to the width of the glue collecting plate 10.

[0017] When it is necessary to dispense glue on LED boards with different widths during the glue dispensing process and handle the excess glue, first, the operator places the LED board on the working board 2. Then, the operator starts the two first cylinders 5, and the two first cylinders 5 drive the flat plate 6 to move vertically. The flat plate 6 drives the first motor 12 to move.

When there is excess glue overflowing from the LED board, at this time, the operator can start the third cylinder 7. The telescopic end of the third cylinder 7 drives the scraper 9 to move horizontally until the scraper 9 is translated to one side of the glue collecting plate 10 and abuts against the glue collecting plate 10. And through the provided stop edge 11, it can be ensured that when the scraper 9 scrapes the glue and collects it on the glue collecting plate 10, the glue will not overflow back onto the LED board due to too much glue.

[0018] Such as Figure 2 and Figure 3 On the support plate 16, a glue dispensing assembly vertically facing the working board 2 is fixedly provided.

[0019] When it is necessary to perform glue dispensing operations on the LED board placed on the working board 2, first, the operator starts the second cylinder 17. The telescopic end of the second cylinder 17 drives the pressing plate 18 to move vertically until the pressing plate 18 contacts the extrusion head 20. Through the extrusion of the extrusion head 20, the glue is pressed out from the glue tank 19 and coated on the LED board. The extrusion methods in this application document are all prior arts, and will not be elaborated too much in the text.

[0020] Such as Figure 1 、 Figure 2 and Figure 3, further comprising a second motor 21 and a second rotating shaft 22 in a lead screw structure. The second motor 21 is fixedly installed at one end of the workbench 1. The second rotating shaft 22 is fixedly installed at the output end of the second motor 21 and is screwed through the sliding frame 4. It further comprises a third motor 24, a third rotating shaft 25 in a lead screw structure and a third guiding block 26. A second long strip-shaped groove 27 is respectively formed on the side walls at both ends of the workbench 1, and both second long strip-shaped grooves 27 are located above the two first long strip-shaped grooves 3. The two ends of the work plate 2 are respectively slidably installed on the two second long strip-shaped grooves 27. The third motor 24 is fixedly installed on one side of the workbench 1.

[0021] When it is necessary to perform glue dispensing work on LED boards of different lengths, the operator starts the second motor 21. The second motor 21 drives the second rotating shaft 22 to rotate, and the second rotating shaft 22 drives the sliding frame 4 to move. In this way, the glue dispensing device on the support plate 16 can be driven to move. When it is necessary to move a sufficient position during the glue dispensing process of the LED board to meet the glue dispensing requirements, at this time, the operator starts the third motor 24. The third motor 24 drives the third rotating shaft 25 to rotate, the third rotating shaft 25 drives the third guiding block 26 to move, and the third guiding block 26 drives the work plate 2 to move. Then, the LED boards are placed through the two placement grooves 30 provided on the work plate 2, and the LED boards can be stabilized on the placement grooves 30 through the cooperation of the compression springs 28 and the pressing plates.

[0022] Working principle:

[0023] When it is necessary to dispense glue on LED boards with different widths during the glue dispensing process and handle the excess glue, first, the operator places the LED board on the working board 2. Then, the operator starts the two first cylinders 5. The two first cylinders 5 drive the flat plate 6 to move vertically, and the flat plate 6 drives the first motor 12 to move. Next, the operator starts the first motor 12. The first motor 12 drives the first rotating shaft 13 to rotate, and the first rotating shaft 13 drives the first guide block 15 to move on the guide rail 14. And this first guide block 15 simultaneously drives the support plate 16 to move, and the support plate 16 drives the glue dispensing assembly to move. Then, the operator starts the glue dispensing assembly to perform glue dispensing operations on the LED board placed on the working board 2. When there is excess glue overflowing from the LED board, at this time, the operator can start the third cylinder 7. The telescopic end of the third cylinder 7 drives the scraper 9 to move horizontally until the scraper 9 is translated to one side of the glue receiving plate 10 and abuts against the glue receiving plate 10. And through the provided retaining edge 11, it can prevent the scraper 9 from re-overflowing the glue onto the LED board when scraping and collecting the glue onto the glue receiving plate 10. By this method, glue dispensing work can be carried out on LED boards with different widths, improving work efficiency and preventing the quality of the LED board from being damaged due to glue overflow during glue dispensing on the working board 2.

[0024] When it is necessary to perform glue dispensing operations on the LED board placed on the working board 2, first, the operator starts the second cylinder 17. The telescopic end of the second cylinder 17 drives the pressing plate 18 to move vertically until the pressing plate 18 contacts the extrusion head 20. Through the extrusion of the extrusion head 20, the glue is pressed out from the glue tank 19 and coated on the LED board. When it is necessary to perform glue dispensing work on LED boards with different lengths, the operator starts the second motor 21. The second motor 21 drives the second rotating shaft 22 to rotate, and the second rotating shaft 22 drives the sliding frame 4 to move. By this method, the glue dispensing equipment on the support plate 16 can be driven to move. When it is necessary to move a sufficient position to meet the glue dispensing requirements during the glue dispensing process of the LED board, at this time, the operator starts the third motor 24. The third motor 24 drives the third rotating shaft 25 to rotate, and the third rotating shaft 25 drives the third guide block 26 to move. The third guide block 26 drives the working board 2 to move. Then, the two placement grooves 30 provided on the working board 2 are used to place the LED board, and through the cooperation of the compression spring 28 and the pressing plate, the LED board can be stabilized on the placement groove 30.
