Description

Technical Field

[0001] The utility model belongs to the technical field of tire pressure sensor production, and relates to a PCBA board positioning device for tire pressure sensor production. Background Art

[0002] Tires are a crucial component of a vehicle's driving mechanism. As crucial supporting and driving elements, they not only bear the vehicle's entire mass, but also provide propulsion and mitigate ground impact. Tires play a crucial role in a vehicle's handling stability, ride quality, safety, comfort, and fuel economy. To ensure safe driving, a common method is to install a tire pressure monitoring system (TPMS) on vehicles. This system monitors tire pressure and other parameters in real time, providing visual and audible warnings for low tire pressure caused by leaks, as well as blowouts caused by high temperatures and high tire pressure.

[0003] Existing tire pressure sensors are mostly produced using PCBAs to carry the corresponding programs. After the tire pressure sensor PCBA board is produced, it needs to be placed under a burner to burn the corresponding program onto the PCBA board. However, the existing tire pressure sensor PCBA board needs to be manually placed under the burner and manually positioned so that the tire pressure sensor PCBA board is directly under the burner. The placement speed is slow, which affects the burning efficiency of the tire pressure sensor PCBA board. Therefore, this paper proposes a PCBA board positioning device for tire pressure sensor production. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a PCBA board positioning device for tire pressure sensor production. The technical problem to be solved by this device is: how to quickly position the tire pressure sensor PCBA board and improve the burning efficiency of the tire pressure sensor PCBA board.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] A PCBA board positioning device for tire pressure sensor production includes a mounting plate and a support assembly. The support assembly includes two fixed plates, both of which are fixed above the mounting plate. A T-slot plate is fixed above the two fixed plates. A push groove and a plurality of sliding grooves are provided above the T-slot plate. The push groove and the plurality of sliding grooves are perpendicular to each other. A burner is fixed above the mounting plate. The burner is located on the side of the T-slot plate. A clamping assembly is provided between the two fixed plates, and an extrusion assembly is provided below the T-slot plate.

[0007] Four supporting legs are fixed below the mounting plate, and a fixing rod is fixed between the four supporting legs.

[0008] With the above structure, the four legs can support the mounting plate, and the fixing rod can increase the stability of the four legs.

[0009] The clamping assembly includes a clamping motor and a bidirectional threaded rod. The bidirectional threaded rod is rotatably arranged between two fixed plates. Two movable plates are rotatably arranged on the bidirectional threaded rod. Two clamping plates are fixed above the two movable plates. The clamping plates are slidably arranged inside sliding grooves at corresponding positions. The clamping motor is fixed above one of the fixed plates, and the output shaft of the clamping motor is connected to the bidirectional threaded rod through a coupling.

[0010] With the above structure, the clamping motor drives the bidirectional threaded rod to rotate through the output shaft, and the bidirectional threaded rod drives the two movable plates to move synchronously in opposite directions. The movable plate drives the clamping plate to slide inside the sliding groove, thereby squeezing and positioning the PCBA board.

[0011] The extrusion assembly includes an electric push rod, which is fixed under the T-slot plate. A connecting plate is fixed to the end of the electric push rod, an L-shaped plate is fixed to the connecting plate, an oblique stopper is rotatably arranged above the L-shaped plate, and a spring is arranged between the oblique stopper and the L-shaped plate.

[0012] With the above structure, the electric push rod contracts to drive the connecting plate to move, the connecting plate drives the L-shaped plate to move, the L-shaped plate drives the oblique stopper to move, and the oblique stopper drives the PCBA board to move, so that the PCBA board contacts the T-slot plate.

[0013] Compared with the existing technology, this PCBA positioning device for tire pressure sensor production has the following advantages:

[0014] Through the cooperation of the supporting assembly, clamping assembly and extrusion assembly, the electric push rod contracts to drive the connecting plate to move, the connecting plate drives the L-shaped plate to move, the L-shaped plate drives the oblique block to move, and the oblique block drives the PCBA board to move, so that the PCBA board contacts the T-slot plate. The clamping motor drives the bidirectional threaded rod to rotate through the output shaft, and the bidirectional threaded rod drives the two moving plates to move synchronously in opposite directions. The moving plate drives the clamping plate to slide inside the sliding groove, thereby squeezing the PCBA board into position, accelerating the positioning speed of the tire pressure sensor PCBA board and improving the burning efficiency of the tire pressure sensor PCBA board.
