[0002] SMT (Surface Mount Technology) is an abbreviation for a series of processes performed on a PCB (Printed Circuit Board). SMT is a surface mount technology, one of the most popular technologies and processes in the electronics assembly industry.

[0003] A review of the publicly disclosed SMT adhesive curing device (CN218244010U) reveals that it includes a frame, a control mechanism on the surface of the frame, a control platform, a cylinder fixedly connected to the surface of the frame, a connecting frame fixedly connected to the bottom of the cylinder, a control box fixedly connected to the surface of the connecting frame, a blower fixedly connected to the surface of the control box, a through hole on the surface of the control box, a support frame slidably connected to the surface of the control box, a positioning hole on the surface of the support frame, a heating wire fixedly connected to the surface of the positioning hole, a control switch on the surface of the control platform, and a mounting mechanism on the surface of the frame. Through the control mechanism, the entire device allows for convenient heating and curing of the SMT adhesive by the blower by controlling the switch of the heating wire.

[0004] However, the above-mentioned SMT adhesive curing device has the following disadvantages: 1. Although the curing device in this patent can conveniently heat and cure the adhesive on the circuit board, the heating wire is fixed in the positioning hole of a single support frame during use. It is not possible to control the temperature of different areas individually during heating. Therefore, this device cannot meet the needs of circuit boards that require different fixed temperatures.

[0005] To address the aforementioned issues, this application proposes an SMT adhesive curing device. Summary of the Invention

[0007] Therefore, the specific technical solution adopted by this utility model is as follows: An SMT adhesive curing device includes a workbench, a turntable assembly installed in the middle of the workbench, a support installed on the upper left side of the workbench, a horizontal plate fixedly installed on the right side wall of the support, a lifting rod installed at the bottom of the horizontal plate, an equipment frame fixedly installed at the bottom of the lifting rod, and a curing assembly installed inside the equipment frame. The curing component includes an air duct. One end of the air duct passes through the top wall of the equipment frame and is connected to the air outlet of the fan. The other end of the air duct is connected to an auxiliary pipe. A connecting pipe is connected to the bottom wall of the auxiliary pipe, and three sets of connecting pipes are provided. An electrically controlled valve is installed on the connecting pipe, and a heating device is connected to the bottom end of the connecting pipe.

[0008] As a further embodiment of this utility model, the heating device includes an inlet pipe, the top end of which is connected to a connecting pipe, a guide cover is installed at the bottom end of the inlet pipe, and a heating wire is installed in the inner cavity of the lower section of the inlet pipe.

[0009] As a further embodiment of this utility model, the inlet pipe and the connecting pipe are also provided in three sets, and the heating wires in the inner cavities of the three sets of inlet pipes operate independently.

[0010] As a further embodiment of this utility model, the fan is installed on the top of the equipment frame, and a protective cover is installed on the bottom outer wall of the equipment frame by bolts.

[0012] As a further embodiment of this utility model, support legs are fixedly installed at the four corners of the bottom of the workbench.

[0013] As a further embodiment of this utility model, a controller is installed on the front side wall of the support, and the controller is electrically connected to the drive motor, the lifting rod, the fan, the electrically controlled valve and the heating device respectively.

[0014] The beneficial effects of this utility model are as follows: This invention utilizes a controller, lifting rod, equipment frame, fixing components, and turntable assembly that work together. During operation, the air duct and auxiliary pipe work together to deliver airflow from the fan into different connecting pipes, which then pass through heating wires inside the inlet pipes to heat the circuit board on the turntable body below. After heating is complete, the heating wires are turned off, and the airflow generated by the fan continues to cool and solidify the circuit board below.
