[0017] Figure 2 This is a top view of the support plate of this utility model. Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] Reference Figure 1-2 A high-precision dispensing machine for sealing optical wave tubes is provided. The dispensing machine includes a dispensing platform 1, which serves as the supporting foundation for the entire dispensing machine. The horizontal arrangement of the dispensing platform 1 ensures the stability of the overall structure and the convenience of operation.
[0020] A horizontally arranged support plate 2 and a driving device 3 for driving the support plate 2 to move horizontally on the dispensing platform 1 are installed on the dispensing platform 1. The support plate 2 is designed to facilitate the placement of the light wave tube and can withstand various forces during the dispensing process. Preferably, the support plate 2 is rectangular in shape and made of metal (such as stainless steel), which has good strength and stability. To facilitate the placement of the light wave tube, several insertion slots 4 are provided on the top of the support plate 2. Preferably, there are 2-5 insertion slots 4. The top of plate 2 is evenly spaced to facilitate the simultaneous placement of multiple optical wave tubes. When dispensing adhesive to one of the optical wave tubes, the dispensed optical wave tube can be removed and replaced, thereby improving dispensing efficiency. More preferably, the insertion slot 4 is cylindrical in shape, and its size matches the outer diameter of the optical wave tube so that the optical wave tube can be accurately inserted into the insertion slot 4. A spherical groove 5 is also connected to the bottom of the insertion slot 4 to facilitate the cooperation with the wire connected to the end of the optical wave tube, providing it with a space to accommodate it and preventing the wire from being damaged due to bending or kinking in the insertion slot 4.
[0021] The driving device 3 is used to drive the support plate 2 to move the optical wave tube, thereby realizing the switching of different optical wave tubes. Preferably, the driving device 3 is a high-precision cylinder, which is horizontally mounted on the dispensing platform 1. The piston rod of the high-precision cylinder is fixedly connected to the support plate 2. The high-precision cylinder has the characteristics of fast response speed and high motion accuracy, and can accurately control the horizontal movement of the support plate 2. By adjusting the air pressure and flow rate of the cylinder, the moving speed and position of the support plate 2 can be precisely controlled so that the support plate 2 can be accurately moved to the designated position so that the dispensing nozzle 10 can perform precise dispensing operation on the optical wave tube.
[0022] To ensure the smooth movement of the support plate 2, a guide slider 6 is installed at the bottom of the support plate 2, and a guide rail 7 that cooperates with the guide slider 6 is set at the top of the dispensing platform 1. The guide slider 6 is slidably installed on the guide rail 7. The guide slider 6 and the guide rail 7 usually adopt a high-precision linear guide pair, which has the advantages of low friction, smooth movement and high precision. At the same time, it can also withstand the lateral force generated by the support plate 2 during movement, thus improving its stability.
[0023] A dispensing tank 8 is installed above the support plate 2 via a bracket to store the adhesive required for dispensing, such as epoxy resin adhesive or polyurethane adhesive. The dispensing tank 8 is usually made of transparent or semi-transparent material so that the operator can intuitively observe the remaining amount of adhesive. The top of the dispensing tank 8 is provided with an adhesive inlet for easy addition of adhesive.
[0024] A vertically arranged dispensing nozzle 10 and a power device for driving the dispensing nozzle 10 to move vertically to insert into the end of the light wave tube for dispensing are installed on the side of the dispensing tank 8. The dispensing nozzle 10 is connected to the bottom of the dispensing tank 8 through a dispensing tube 9. The size and shape of the dispensing nozzle 10 are designed according to the dispensing requirements of the light wave tube, which can accurately control the amount and shape of the glue dispensed. Preferably, the dispensing tube 9 is a flexible plastic tube with good flexibility and corrosion resistance, which can adapt to the vertical movement of the dispensing nozzle 10 and the dispensing needs at different positions.
[0025] A dispensing control valve 12 and a peristaltic pump 11 are installed on the dispensing tube 9. The dispensing control valve 12 is used to control the flow of glue, while the peristaltic pump 11 precisely controls the flow rate and pressure of glue by squeezing the tube, thereby achieving precise control of the dispensing process.
[0026] During the dispensing process, a power unit is used to drive the dispensing nozzle 10 to insert into the end of the optical wave tube for dispensing operation. Preferably, the power unit is a high-precision ball screw. The lead screw 13 of the high-precision ball screw is vertically mounted on the side of the dispensing tank 8 through a bearing and bearing seat. The dispensing nozzle 10 is fixedly mounted on the nut 14 of the high-precision ball screw. A servo motor 16, which is connected to the lead screw 13 of the high-precision ball screw, and a guide rod 15, which passes through the nut 14 of the high-precision ball screw, are installed on the dispensing tank 8. The servo motor 16 achieves precise position control of the dispensing nozzle 10 through the nut 14 by precisely controlling the rotation angle and speed of the lead screw 13. The guide rod 15 prevents the nut 14 from rotating during movement, ensuring that the dispensing nozzle 10 always maintains vertical movement and improving the dispensing accuracy.
[0027] To ensure that the light wave tube can accurately stop directly below the dispensing nozzle 10 and achieve high-precision dispensing operation, a limit switch 17 that cooperates with the support plate 2 is also installed on the dispensing platform 1 directly below the dispensing nozzle 10. A trigger plate 18 that cooperates with the operating head of the limit switch 17 is set on the support plate 2 at the insertion slot 4. The function of the limit switch 17 is to limit the movement range of the support plate 2. When the support plate 2 moves to the preset position, the trigger plate 18 will trigger the operating head of the limit switch 17. The limit switch 17 sends a signal to control the drive device 3 to stop moving, thereby ensuring that the support plate 2 moves accurately to the designated position, thereby improving the accuracy and reliability of dispensing and avoiding dispensing errors caused by excessive movement of the support plate 2.
[0028] The high-precision dispensing machine for sealing optical wave tubes provided in this application is used as follows:
[0029] During operation, the optical wave tube is first inserted into the insertion slot 4 on the support plate 2. The spherical groove 5 stores the wires connected to the end of the optical wave tube. Then, the high-precision cylinder drives the support plate 2 to move laterally. When the support plate 2 moves to the designated position, the trigger plate 18 triggers the limit switch 17 to stop the movement. Next, the servo motor 16 drives the screw 13 of the high-precision ball screw to rotate, causing the nut 14 to drive the dispensing nozzle 10 to move vertically and insert into the end of the optical wave tube. At the same time, the dispensing control valve 12 opens, and the peristaltic pump 11 starts working, delivering the glue in the dispensing tank 8 to the dispensing nozzle 10 through the dispensing tube 9 to achieve precise dispensing of the optical wave tube. After dispensing is completed, the dispensing control valve 12 closes, the peristaltic pump 11 stops working, and the dispensing nozzle 10 moves upward under the action of the power device, leaving the optical wave tube. Then, the high-precision cylinder drives the support plate 2 to move to the position of the next optical wave tube, repeating the above dispensing process until the support plate 2 moves to the limit position, and then moves in the opposite direction, and so on.
[0030] During this period, workers can remove the light wave tube after it has been glued and replace it with a new light wave tube to be glued. The removed light wave tubes are stored together and, after the glue dries, they are inverted and inserted into the insertion slot 4 to perform the glue dispensing operation on the other end. After the light wave tubes have been glued on both ends, they can be sent to the drying oven for drying to accelerate the curing of the glue and achieve the sealing operation of the light wave tube.
