Description

Technical Field

[0001] The present application relates to the technical field of glue supply equipment, and in particular to a non-stop glue supply system. Background Art

[0002] The production process of LED, LCD, plastic toys, and resin crafts involves the step of dispensing glue. During the dispensing process, the glue produced by the glue manufacturer cannot be used directly. It needs to be degassed by degassing equipment and then supplied to the dispensing valve by the degassing machine for dispensing.

[0003] The degassing device is provided with a glue outlet nozzle connected to the glue dispensing nozzle. After degassing is completed, the glue outlet nozzle is opened to supply glue to the glue dispensing valve. During the degassing process, the glue outlet nozzle needs to be closed to reduce the occurrence of colloid mixed with bubbles entering the glue dispensing valve.

[0004] During the dispensing process, when the colloid in the degassing device is used up, the staff needs to close the dispensing valve, and then add colloid to the degassing device for degassing. After the degassing is completed, the dispensing can be performed again. This process takes a long time, resulting in low overall product production capacity. Utility Model Content

[0008] By adopting the above technical solution, both groups of injection-type glue supply structures can inject glue into the collection cavity, and then discharge it from the glue outlet. The glue outlet is connected to the glue dispensing valve, and multiple groups of injection-type glue supply structures work alternately to inject glue into the collection cavity, so that the glue outlet can continuously supply glue to the glue dispensing valve.

[0015] Optionally, the driving member is provided in plurality, and the plurality of driving members are evenly spaced along the circumference of the cylinder body.

[0016] By adopting the above technical solution, the setting of multiple driving parts can, on the one hand, increase the power of driving the piston during movement, and on the other hand, make the connecting frame more evenly stressed, thereby making the piston evenly stressed and improving the stability of the piston during movement.

A collecting chamber 111 is provided inside the collecting piece 11, and the glue inlet 112 and the glue discharge port 113 are both connected to the inside of the collecting chamber 111. During the dispensing process, the colloids of the two groups of extraction-type glue supply structures 2 are alternately injected into the collecting chamber 111, so that the glue discharge port 113 can continuously discharge glue.

[0030] Reference Figure 2 The injection type glue supply structure 2 includes a cylinder body 22 and a piston 23. The cylinder body 22 is a cylindrical shell structure with an opening at one end. The piston 23 is slidably fitted in the cylinder body 22 along the length direction of the cylinder body 22. The glue nozzle 21 is arranged at the bottom of the cylinder body 22. The sliding piston 23 can squeeze the colloid inside the cylinder body 22 out of the glue nozzle 21. A solenoid valve is arranged at the glue nozzle 21 to facilitate the control of the opening and closing of the glue nozzle 21. An exhaust hole 24 is arranged on the piston 23, and a solenoid valve is connected to the exhaust hole 24 to control the opening and closing of the exhaust hole 24. Closing the solenoid valve at the glue nozzle 21 and moving the piston 23 can squeeze the colloid, and at the same time, the bubbles are discharged from the exhaust hole 24 to achieve the degassing of the colloid.

[0031] Reference Figure 2 The injection type glue supply structure 2 also includes a driving assembly 3 for driving the piston 23 to move. The driving assembly 3 includes a driving member 31 and a connecting frame 32. The driving member 31 is arranged on one side of the cylinder body 22. The connecting frame 32 includes a connecting rod 321 and a connecting plate 322. The connecting rod 321 is a cylindrical structure. One end of the connecting rod 321 is fixedly connected to the piston 23, and the other end extends to the outside of the cylinder body 22 along the length direction of the cylinder body 22. A through hole is provided at the position of the connecting rod 321 corresponding to the exhaust hole 24 to prevent the connecting rod 321 from blocking the exhaust hole 24. The connecting plate 322 is horizontally arranged above the driving member 31, and the connecting plate 322 is fixedly connected to the connecting rod 321 by screws. The driving member 31 is used to drive the connecting plate 322 to move along the length direction of the cylinder body 22. In this embodiment, the driving member 31 is a cylinder, and the cylinder shell is fixedly connected to the base 1. The piston 23 rod of the cylinder is fixedly connected to the connecting plate 322, so that the connecting plate 322 can be driven to rise and fall, and then the piston 23 can be driven to rise and fall.

[0032] A plurality of driving members 31 can be evenly spaced along the circumference of the cylinder body 22 to increase the power of driving the piston 23 to move. In the present embodiment, two driving members 31 are provided. The two driving members 31 are respectively arranged on both sides of the cylinder body 22. The two driving members 31 are respectively connected to the two ends of the connecting plate 322 to improve the uniformity of the force applied to the connecting plate 322 and improve the stability of the piston 23 during movement.

[0033] Reference Figure 2 The glue supply system also includes an external glue barrel 4 for containing the colloid, and the external glue barrel 4 is arranged between the two groups of injection-drawing glue supply structures 2. A glue supply port 41 is provided at the bottom of the external glue barrel 4, and a glue injection port 25 is provided at the bottom of the cylinder body 22. The glue supply port 41 is connected to the glue injection port 25 through a flexible hose, and a solenoid valve is provided on the flexible hose to control the connection and disconnection between the two. The exhaust hole 24 is closed by controlling the solenoid valve, and the piston 23 is moved, and negative pressure can be generated inside the piston 23, so that the colloid inside the external glue barrel 4 is drawn into the cylinder body 22 to achieve glue addition.

[0034] Reference Figure 2 A circulation pipe 5 is provided between the external glue barrel 4 and the exhaust hole 24, one end of the circulation pipe 5 is connected to the inside of the external glue barrel 4, and the other end is connected to the through hole on the connecting rod 321. In the process of exhaust colloid degassing, the colloid mixed with bubbles enters the external glue barrel 4 for circulation, reducing waste.

[0035] Reference Figure 2 A pressure sensor 6 is provided below the external glue barrel 4, and the external glue barrel 4 is fixedly connected to the pressure sensor 6. The pressure sensor 6 is electrically connected to the controller, and can send the weight information of the external glue barrel 4 to the controller. When the colloid inside the external glue barrel 4 is less, the controller can control the buzzer to alarm, thereby prompting the staff to add glue to the external glue barrel 4 to reduce the occurrence of glue shortage.

[0036] The implementation principle of a non-stop glue supply system in the embodiment of the present application is as follows: during the glue supply process, one group of the extraction type glue supply structure 2 operates to inject glue into the collection chamber 111. When the glue inside the cylinder 22 of the extraction type glue supply structure 2 is used up, the other group of the extraction type glue supply structure 2 supplies glue into the collection chamber 111. While the other group of the extraction type glue supply structure 2 is supplying glue, the extraction type glue supply structure 2 can suck the glue inside the external glue barrel 4 to perform a degassing process, thereby realizing the alternating glue supply of the two groups of the extraction type glue supply structures 2, ensuring that the glue outlet nozzle 21 on the collection piece 11 can continuously discharge glue, and improving the production capacity of the glue dispensing valve.
