[0036] The UV adhesive dispensing fixture of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0037] Reference Figures 1 to 3 As shown, the UV adhesive dispensing fixture provided in this embodiment of the present invention is used to dispense and fix the connector 401 on the circuit board 40. It includes: a base plate 10, a positioning seat 20 and an adhesive injection assembly 30. The positioning seat 20 is disposed on the base plate 10 and is used to install and position the circuit board 40. The adhesive injection assembly 30 is detachably disposed on the positioning seat 20 and together with the connector 401 defines an adhesive injection cavity P10 so that UV adhesive can be injected into the adhesive injection cavity P10 through the adhesive injection assembly 30.

[0038] The UV adhesive dispensing fixture provided by this utility model can mount the circuit board 40 on the positioning seat 20 and clamp and fix it together with the dispensing component 30 and the positioning seat 20, so that the dispensing component 30 and the connector 401 can form a dispensing cavity P10, and then the UV adhesive can be injected from the dispensing component 30 into the dispensing cavity P10, making the dispensing method simpler and preventing the connector 401 from falling off the circuit board 40, thus improving its stability.

[0039] Reference Figure 5As shown, the positioning base 20 includes a support portion 201 and a relief groove 202. The support portion 201 surrounds the edge of the relief groove 202 and supports the circuit board 40 to suspend it above the relief groove 202. Furthermore, the relief groove 202 is provided with a plurality of mounting holes 204, which are used to install pins to support the circuit board 40.

[0040] In this embodiment, the circuit board 40 can be placed on the clearance groove 202, which supports the edge of the circuit board 40 and the support part 201. At the same time, the bottom of the circuit board 40 is supported by the pins in the clearance groove 202, so that the circuit components at the bottom of the circuit board 40 can be avoided, and the circuit board 40 is not easy to move during the dispensing process, which can ensure that the circuit board 40 is supported more stably.

[0041] Furthermore, the support 201 is provided with a positioning groove 203, which is adapted to the circuit board 40 to restrict the horizontal movement of the circuit board 40. The positioning groove 203 supports and positions the edge of the circuit board 40, allowing the circuit board 40 to be suspended on the clearance groove 202. The circuit board 40 is then supported by pins to avoid circuit components, making it more convenient to use.

[0042] Reference Figure 4 As shown, the glue injection assembly 30 includes: a positioning plate 31 and a glue injection component 32. The positioning plate 31 is used to engage with the positioning seat 20. The glue injection component 32 is detachably disposed on the positioning plate 31 and is adapted to fit into the connector 401. Further, the glue injection component 32 includes: an engaging part 321 and a molding part 322. The engaging part 321 engages with the positioning plate 31. The molding part 322 is disposed on the engaging part 321 and is close to the side of the positioning plate 31 facing the circuit board 40.

[0043] In this embodiment, when the molding part 322 and the connector 401 are in close contact, a glue injection cavity P10 can be formed between the molding part 322 and the connector 401. The glue injection cavity P10 can correspond to the pin portion of the connector 401. When injecting UV glue, the UV glue can enter the molding part 322 from the engaging part 321, thereby ensuring that the UV glue wraps the pin portion of the connector 401 and preventing the UV glue from covering other parts of the connector 401. After the glue is applied, the positioning plate 31 and the positioning seat 20 are separated, and the UV glue on the circuit board 40 is cured. Optionally, the glue injection part 32 can be made of rubber or other materials, which makes it easier to assemble the glue injection part 32 and the positioning plate 31, and can better separate the pin portion of the connector 401 from other parts, making the glue application more convenient and simple.

[0044] Optionally, the engaging portion 321 to the molding portion 322 are formed with semi-cylindrical through holes 323, and when the molding portion 322 abuts against the connector 401, the through holes 323 and at least a portion of the connector 401 are not interconnected. The through holes 323 can be directly aligned with the pins of the connector 401, allowing UV adhesive to directly cover the pins of the connector 401, making adhesive application faster and more convenient.

[0045] Reference Figure 5 As shown, the base plate 10 is also provided with a limiting seat 50, which is located on both sides of the positioning seat 20 in the length direction to limit the height of the positioning plate 31; furthermore, the limiting seat 50 is provided with a positioning post 501, and the positioning plate 31 is provided with a positioning hole corresponding to the positioning post 501. The positioning post 501 is used to be inserted into the positioning hole to limit the movement of the positioning plate 31.

[0046] In this embodiment, the positioning plate 31 can be installed and fixed with the limiting seat 50, so that the height of the positioning plate 31 can be limited by the limiting seat 50. At the same time, the positioning plate 31 and the positioning seat 20 can clamp and fix the circuit board 40 together, making the circuit board 40 more stable during the dispensing process.
