[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs; the terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the present application; the description herein and the claims of the present application together with the drawings serve to explain by way of example the principles of the present application. As used herein, the indefinite articles "a" and "an" mean "one or more" unless otherwise defined.

[0023] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that the embodiments described herein are merely examples from a multitude of embodiments that are of the application. Numerous variations and modifications supporting equivalents can be effected without departing from the spirit and scope of the application as defined in the claims.

[0024] In order to make the technical personnel in the technical field better understand the present application scheme, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings.

[0025] With reference to Figure 1 An embodiment of the present application discloses a vacuum glue injection equipment for injecting glue to products, comprising a vacuumizing device 1, a first conduit 2, a second conduit 3, a glue raw material bin 4, a first valve 5 arranged on the first conduit 2, a second valve 6 arranged on the second conduit 3, two ends of the first conduit 2 being a first conduit first end 201 and a first conduit second end 202 respectively, two ends of the second conduit 3 being a second conduit first end 301 and a second conduit second end 302 respectively, the first conduit first end 201 being connected with the vacuumizing device 1, the second conduit first end 301 being connected with the glue raw material bin 4, the first conduit second end 202 and the second conduit second end 302 being used for connecting with products 9 when injecting glue to the products 9.

[0026] In use, the first conduit second end 202 and the second conduit second end 302 are connected to the product 9 to be injected with glue, the second valve 6 is closed, the vacuumizing device 1 is opened to vacuumize the product 9 to be injected with glue, after the preset vacuum degree is reached, the vacuumizing device 1 is closed, the second valve 6 is opened, and the glue in the glue raw material bin 4 is injected into the product 9 to be injected with glue; when the injection space in the product 9 to be injected with glue is filled, a small amount of excess glue will enter the first conduit 2, at this time, the first valve 5 is closed, and the second valve 6 is closed, and the glue injection is stopped. Then the first conduit 2 and the second conduit 3 are taken off from the vacuumizing device 1 and the glue raw material bin 4, and the product connected with the first conduit 2 and the second conduit 3 with the closed valve is placed in the glue curing device for curing. After curing, the first conduit 2 and the second conduit 3 are directly pulled out, although local glue layer damage will be caused at the connection, but it does not affect the whole. In particular, the product 9 injected with glue by the vacuum glue injection equipment of the embodiment will be used for hole opening and wiring in subsequent steps, so even if the first conduit 2 and the second conduit 3 are pulled out in the process, local glue layer damage will not cause substantial impact on product quality.

[0027] The utility model discloses simple structure design, low manufacturing cost, easy to assemble, debugging and maintenance, and relatively smaller volume, and the requirement of lower to use environment and space, therefore can adapt to more diversified application scene.

[0028] Reference Figure 2 In one specific embodiment, the first conduit second end 202 is provided with a first connection assembly 7, which is a hollow structure, and includes a first connection assembly first end 701 and a first connection assembly second end 702 opposite to each other. The first connection assembly first end 701 is inserted into the first conduit second end 202, and the first connection assembly second end 702 is connected to the product 9 when injecting glue into the product.

[0029] In the embodiment, the first connection assembly 7 is used to connect the product 9 and the first conduit 2. For the first conduit 2 made of plastic pipe material, it is difficult to insert into the glue injection port of the product 9 to be injected with glue, and it is easy to fall off from the glue injection port during vacuumizing. The use of the first connection assembly 7 for connection can ensure the close connection of the first conduit 2 and the product glue injection port.

[0030] Specifically, the second end 702 of the first connecting component is provided with a thread outside. Correspondingly, a thread is provided at the glue injection port of the product, and the second end 702 of the first connecting component is stably connected to the product by the threaded connection. Since the plastic material has elasticity, the first end 701 of the first connecting component can be directly inserted into the second end 202 of the first conduit. In this way, reliable connection of the first conduit 2, the first connecting component 7 and the glue injection port of the product is achieved.

[0031] Referring to Figure 3 In one specific embodiment, the second end 302 of the second conduit is provided with a second connecting component 8. The second connecting component 8 is a hollow structure, and includes opposite first and second ends 801 and 802. The first end 801 is inserted into the second end 302 of the second conduit, and the second end 802 is connected to the product during glue injection. In one specific embodiment, the second end 802 of the second connecting component is provided with a thread outside. The second connecting component 8 is similar to the first connecting component 7, and will not be described here.

[0032] In one specific embodiment, the first connecting component 7 and the second connecting component 8 are made of a material with rigidity, which facilitates insertion into the first conduit 2 and the second conduit 3, and facilitates the provision of a threaded structure at the ends of the first connecting component 7 and the second connecting component 8.

[0033] Referring to Figure 4 In one specific embodiment, the vacuum device 1 includes a vacuum pump 101 and a glue buffer tank 102. The vacuum pump 101 is connected to the glue buffer tank 102, and the glue buffer tank 102 is connected to the first end 201 of the first conduit. During glue injection, in order to ensure that the glue injection space in the product 9 to be injected is filled, a small amount of glue needs to be overflowed from the first conduit 2 before the glue injection is stopped. The glue buffer tank 102 is provided to store the glue that may overflow from the first conduit 2, so as to prevent excess glue from entering the vacuum pump 101.

[0034] In one specific embodiment, the vacuum device 1 further includes a vacuum gauge (not shown in the figure) installed on the glue buffer tank 102. The vacuum gauge is used to measure the vacuum degree, so as to determine whether to stop vacuumizing when the preset vacuum degree is reached.

[0035] Referring to Figure 1In one embodiment, the glue raw material bin 4 is an open container, and the height of the glue raw material bin 4 relative to the product can be adjusted when injecting glue into the product. When the vacuum is completed, the second valve 6 is opened, and the atmospheric pressure of the external air directly presses the glue into the second conduit 3, thereby achieving glue injection. The height of the glue raw material bin 4 can be adjusted according to the viscosity of the glue. For glue with high viscosity, the height of the glue raw material bin 4 relative to the product can be increased, thereby facilitating glue injection. For glue with low viscosity, the height of the glue raw material bin 4 relative to the product can be appropriately reduced, thereby achieving gentle glue injection.

[0036] Referring to Figure 4 In one embodiment, the glue raw material bin 4 is a closed container, and a piston 401 is arranged on the glue raw material bin 4. The glue in the glue raw material bin 4 is injected into the product through the second conduit 3 by the piston 401. For the closed glue raw material bin 4, the piston 401 is used to inject glue. For glue with different viscosities, the force and speed of pushing and pulling the piston 401 can be adjusted to adjust the glue injection speed.

[0037] In use, the first conduit second end 202 and the second conduit second end 302 are connected to the product to be injected with glue, the second valve is closed, the vacuum device 1 is opened to perform vacuumization on the product to be injected with glue, the vacuum device 1 is closed after reaching the preset vacuum degree, and the second valve 6 is opened to inject the glue in the glue raw material bin 4 into the product to be injected with glue. The effective vacuum glue injection process can be ensured. The vacuum glue injection device has simple structure, low manufacturing cost, and is easy to assemble, debug, and maintain. The device has relatively small size and low requirements on the use environment and space, and can thus adapt to more diversified application scenarios.

The preferred embodiments of the present application are shown in the drawings, but do not limit the patent scope of the present application. The present application can be implemented in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
