In order to improve the air tightness of LED lamp beads, the viscosity of the packaging glue is also gradually increasing. The problem that comes with it is that the greater the viscosity, the worse the fluidity, resulting in more wall residues in the glue tank. The wall residues in the glue cup account for about 15%, the glue loss is too much, and the cost is high.

[0004] In view of this, how to design a low-loss glue tank is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] refer to Figure 1 and Figure 2 The present application provides a glue tank, comprising a glue tank body 1, wherein the glue tank body 1 comprises a tank body 11 and a tank bottom 12, wherein the outer wall of the tank body 11 is provided with a plurality of clamping parts 13 distributed along the circumference of the tank body 11, wherein each clamping part 13 is adapted to be one-to-one correspondingly matched to each degassing machine base slot, and the glue tank body 1 is clamped in the degassing machine base slot.

[0028] The tank bottom 12 is an inverted conical tank bottom, and a glue outlet is provided at the bottom of the tank bottom 12. Correspondingly, a bottom cover 2 is adapted to the glue outlet of the tank bottom 12, and the bottom cover 2 is connected to the glue outlet of the tank bottom 12 to achieve blocking of the glue outlet. Correspondingly, an inverted conical cavity is provided at the base of the degassing machine to adapt to the inverted conical tank bottom and fix the glue tank.

[0029] like Figure 3 A bottom cover 2 is installed at the glue outlet of the tank bottom 12, and the bottom cover 2 is adapted to be connected with the tank bottom 12 to seal the glue at the glue outlet.

[0030] When using the glue pot provided in this application to produce LED lamp beads, perform the following steps:

[0031] Step 1: Install the bottom cover 2 at the glue outlet of the tank bottom 12;

[0032] Step 2: Prepare glue;

[0033] Step 3: Fix the glue tank body 1 with the bottom cover 2 installed in the card slot of the degassing machine base;

[0034] Step 4: Remove the bottom cover 2, connect the top to the dispensing machine vacuum tube, and directly connect the tank bottom 12 to the dispensing valve body;

[0035] Step 5: Produce LED lamp beads.

[0036] In this solution, the glue is directly added to the machine for production after being prepared, which reduces the loss of glue turnover and reduces production costs.

[0037] In a specific embodiment, the bottom cover 2 and the outer wall of the glue outlet can be connected by threads or the like.

[0038] Specifically, the outer wall of the glue outlet is provided with a first external thread, and the inner wall of the bottom cover 2 is provided with a circle of first internal threads. The bottom cover 2 is screwed to the first external thread of the glue outlet through the first internal threads, thereby realizing the connection between the bottom cover 2 and the tank bottom 12.

[0039] In addition, the bottom cover 2 and the outer wall of the glue outlet can also be connected by snap connection, bolt connection, etc.

[0040] like Figure 4 and Figure 5 Furthermore, a glue tank cover 3 is installed at the glue inlet of the tank body 11 , and the glue tank cover 3 can be connected to the tank body 11 by snapping, bolting or threading.

[0041] When degassing, cover the glue tank cover 3 to seal the glue inlet at the top to prevent glue from flowing out. When dispensing glue, remove the glue tank cover 3 and directly connect the dispensing machine vacuum tube to facilitate vacuum connection.

[0042] Regarding the connection relationship between the can body 11 and the plastic jar cover 3, specifically, the outer wall of the cup mouth of the can body 11 is provided with a circle of second external threads, and the inner wall of the plastic jar cover 3 is provided with a circle of second internal threads. The plastic jar cover 3 is screwed to the second external threads of the can body 11 through the second internal threads, thereby realizing the connection with the can body 11.

[0043] The nominal diameter of the second external thread is larger than the outer diameter of the can body 11, and a transition groove is formed between the bottom edge of the second external thread and the top surface of the can body 11 and the clamping member 13, and the entrance diameter of the transition groove is larger than the bottom inner diameter of the transition groove. This arrangement allows the can body to be firmly clamped in the degassing machine clamping groove, preventing the can body from falling out during degassing, and the installation is more firm and reliable.

[0044] In order to observe the remaining glue in the can body 11 and to observe more intuitively whether the glue is evenly shaken after degassing, a window is provided on the can body 11. The window is made of a transparent material and embedded in the can body 11. The window is provided to facilitate the operator to observe the volume of glue inside the can body 11 through the window. In addition, the can body 11 can also be made of a transparent material to facilitate observation of the remaining glue. The material of the can body 11 can be high temperature resistant polyethylene plastic. The specific material of the can body 11 is not limited herein.

[0045] Furthermore, the window is provided with capacity scale lines, through which the glue capacity can be accurately obtained, and the measurement is more precise.

[0046] The first external threads on the bottom cover 2 and the can body 11 are forward and reverse bidirectional threads. The double-layer threads and embedded structure adopted by the bottom cover 2 and the can body 11 can increase the sealing performance of the upper end of the can body 11.

[0047] Similarly, the second external thread on the outer wall of the can body 11 and the second internal thread on the inner wall of the plastic tank cover 3 are both forward and reverse bidirectional threads to increase the sealing performance of the lower end of the can body 11.

[0048] The present application adjusts the structure of the glue tank to integrate the functions of glue preparation, degassing and glue dispensing, which can reduce the loss of glue hanging on the wall caused by replacing the glue cup during the production process, thereby achieving the purpose of reducing glue loss.

[0049] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0050] The above is a detailed introduction to the glue tank provided by the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
