[0025] Among them, in order to ensure the dispensing accuracy of the first structural part and the second structural part, the flexible assembly production line may also include a jig assembly unit arranged before the dispensing unit, and a curing unit and a jig reflow unit arranged after the dispensing unit; wherein, in the process of the assembly part being transferred to the dispensing unit through the flow tooling, first, the flow tooling where the assembly part is located is assembled with the external dispensing jig through the jig assembly unit; the assembly part is subjected to dispensing treatment by the cooperation of the dispensing jig and the dispensing unit; the dispensing product after the dispensing treatment is subjected to standing, curing and cooling treatment by the curing unit to form a product; the dispensing jig is separated from the flow tooling by the jig reflow unit, and the separated dispensing jig is returned to the jig assembly unit.

[0026] It can be seen that the flexible assembly production line of the embodiment of the present invention includes a loading unit, an assembly unit, a jig assembly unit, a dispensing unit, a curing unit, a jig reflow unit, a preliminary inspection unit and a unloading unit which are arranged in sequence, and qualified products and unqualified products are unloaded and processed separately by the unloading unit; wherein, in order to avoid the entire production line being too long, the detection unit can be separated to form a flexible detection line, that is, the detection unit in the embodiment of the present invention can be used as an independent production line, and can also be connected with the above-mentioned units to form a production line.

[0027] Among them, the preliminary inspection unit is used to inspect the preset position holes, overflow glue and the front and back of the sound holes of the product, which belongs to the preliminary inspection of the appearance, and the inspection unit includes an inspection loading unit, an inspection unloading unit, a PIN height inspection unit, an airtight inspection unit, an electrical connection inspection unit and a front and back inspection unit which are arranged in sequence; among them, the product flows through the inspection loading unit, the front and back inspection unit, the electrical connection inspection unit, the airtight inspection unit, the PIN height inspection unit and the inspection unloading unit in sequence through the inspection assembly line tooling.
