Description

Technical Field

[0001] The utility model belongs to the technical field of tire pressure sensor manufacturing, and relates to a jig for batch burning of tire pressure sensors. Background Art

[0002] Tires are a crucial component of a vehicle's running mechanism. As crucial supporting and driving elements, they not only bear the vehicle's entire weight 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.

[0003] Existing car tires are equipped with tire pressure sensors to monitor tire pressure status in real time, eliminate problems such as insufficient or excessive tire pressure in advance, and improve vehicle driving safety. The tire pressure sensor chip needs to be burned after being installed on the PCB board.

[0004] A search revealed a Chinese patent document [Application No. 202221050507.4; Publication No. CN217280040U], which discloses a jig for batch programming of tire pressure sensors. The jig comprises a support base with support columns and a support plate disposed on its top surface; a snap-in placement mechanism disposed on the top surface of the support base for placing PCBs; and a lifting and fixing mechanism disposed on the side of the support plate proximate the snap-in placement mechanism. The mechanism comprises a sliding lifting assembly and a drive assembly for securing PCBs within a fixing groove. Multiple PCBs can be simultaneously placed within corresponding fixing grooves, where they contact the PCBs via power contacts, ground contacts, and programming contacts disposed within the fixing grooves. The lifting and fixing mechanism then abuts and secures the PCBs within the fixing grooves. This standardized operation reduces labor and costs, ensures the safety of the PCBs during programming, improves production efficiency, and is highly practical. However, removing the PCBs from the fixing grooves after programming is complete is difficult and inconvenient.

[0005] Based on this, we designed a fixture for batch burning of tire pressure sensors. Utility Model Content

[0006] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a jig for batch burning of tire pressure sensors. The technical problem to be solved by this device is: how to automatically eject the PCB board of the tire pressure sensor after burning is completed, to facilitate material removal and improve work efficiency.

[0007] The purpose of this utility model can be achieved through the following technical solutions:

[0008] A jig for batch burning of tire pressure sensors includes a base, wherein the base is provided with a plurality of burning card slots, and the burning card slots are provided with power contacts, burning contacts and ground contacts. A sliding hole is opened at the bottom of the burning card slot, and a push rod is slidably arranged in the sliding hole. Two symmetrically distributed support plates are fixed on both sides of the base, and a horizontal plate is fixed to the upper end of the support plate. An electric push rod is installed above the horizontal plate. The output shaft of the electric push rod passes through the horizontal plate, and a pressure plate is fixed to its end. A pulling assembly for pulling the push rod upward is provided between the pressure plate and the push rod.

[0009] The lifting assembly includes an upper hook fixed on the pressure plate, a sliding groove connected to the sliding hole is opened on the base, a cross bar is fixed to the side end of the top rod, the cross bar is located inside the sliding groove, and a lower hook is fixed to the end of the cross bar away from the top rod.

[0010] With the above structure, when the pressure plate descends and applies pressure to the PCB placed in the burning card slot, the upper hook will engage with the lower hook at the corresponding position. After burning is completed, the pressure plate rises, and the upper and lower hooks can drive the crossbar and the push rod to move upward and lift the PCB. In addition, there is a pressure plate above the PCB to block it, so the PCB will not pop out when it is pushed upward. When the crossbar slides to the upper end, the pressure plate continues to move upward, and the upper and lower hooks will disengage, making it convenient for the operator to remove the material.

[0011] A plurality of damping rubber rings are arranged on the outer side of the push rod, and the damping rubber rings abut against the inner wall of the sliding hole.

[0012] With the above structure, when in use, the damping rubber ring can increase the friction force on the push rod when it moves, so that the push rod will not fall after lifting the PCB board, preventing the PCB board from sliding sideways, thereby improving the protection effect of the PCB board. When placing the PCB board, the operator can directly press the push rod downward, which is convenient and further facilitates the operator's operation.

[0013] Two vertical guide rods are fixed above the pressure plate, and two symmetrically distributed guide holes are provided on the transverse plate, and the guide rods are slidably arranged in the guide holes at corresponding positions.

[0014] With the above structure, when in use, the guide rod can improve the stability of the pressing plate when the pressing plate moves up and down, ensure that the pressing plate will not deviate or tilt, and improve the effect of pressing the PCB board.

[0015] A rubber gasket is provided at the upper end of the push rod, and a plurality of shallow grooves are opened on the upper surface of the rubber gasket. A plurality of soft pressure pads distributed at equal intervals are fixed below the pressure plate.

[0016] With the above structure, when the PCB is pressed, the soft pressure pad and rubber gasket respectively press against the PCB, which can prevent damage to the PCB and chip. In addition, when the ejector lifts the PCB, the solder joints on the PCB will be stuck in the shallow groove, which can prevent the PCB from sliding sideways, further improving the protection effect of the PCB.

[0017] The front end of the base is provided with a plurality of indicator lights, and the indicator lights are located in front of the corresponding positions of the burning card slots.

[0018] With the above structure, when in use, if an error occurs during the burning process or the chip cannot be burned into the program, the corresponding indicator light will flash, prompting the operator that there is a problem with the PCB board in the corresponding burning card slot and that it needs to be repaired, thereby improving product quality.

[0019] Compared with existing technologies, this tire pressure sensor batch programming fixture has the following advantages:

[0020] 1. The base, ejector, pressure plate and lifting assembly can press the PCB tightly during programming to prevent poor contact. After programming is completed, the PCB can be lifted up to detach it from the programming slot, allowing the operator to remove the programmed PCB, making operation more convenient.

[0021] 2. The lifting assembly, rubber gasket and soft pressure pad can improve the protection effect of the PCB board when clamping the PCB board. In addition, the rubber gasket and soft pressure pad can continue to clamp the PCB board during the process of lifting the PCB board to prevent the PCB board from bouncing up and falling. After lifting the PCB board, the shallow groove on the rubber gasket can prevent the PCB board from sliding sideways, further improving the protection effect of the PCB board.

[0022] 3. When an error occurs during the programming process, the corresponding indicator light will flash, prompting the operator that the PCB board or chip in the programming slot at the corresponding position is defective and needs to be repaired, which can improve product quality.
