Description

Technical Field

[0001] The utility model belongs to the technical field of tire pressure sensor manufacturing and relates to a tire pressure sensor patch device. Background Art

[0002] Tires are an important part of a car's driving mechanism. As an important supporting element and running element, tires not only bear the entire weight of the car, but also provide propulsion for the car to move forward and play a role in mitigating ground impact. Tires play a very critical role in the car's handling stability, smoothness, safety, comfort and fuel economy.

[0003] Existing automobile tires are equipped with tire pressure sensors to monitor the tire pressure status in real time, eliminate problems such as insufficient or excessive tire pressure in advance, and improve vehicle driving safety.

[0004] When producing tire pressure sensors in large quantities, automated placement machines are often used to place components in corresponding positions on the PCB circuit board to achieve the effect of automatic placement. However, in small-batch production and preliminary production of experimental products, operators are required to manually place the components. Since a PCB circuit board has multiple components and the components are located close to each other, operators are likely to touch previously placed components when placing components, causing the previously placed components to become skewed and need to be re-placed. This operation is difficult and is not conducive to improving work efficiency.

[0005] Based on this, we designed a tire pressure sensor patch device. Utility Model Content

[0006] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a tire pressure sensor patch device. The technical problem to be solved by the device is: how to reduce the difficulty of manual patching of tire pressure sensors, thereby improving work efficiency.

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

[0008] A tire pressure sensor patch device includes a base plate, a fixed tube is fixed in the middle position of the base plate, a patch plate is rotatably arranged at the bottom of the fixed tube, two symmetrically distributed placement slots are provided on the patch plate, a sliding hole is provided on the fixed tube, a sliding rod is slidably arranged in the sliding hole, a circular hole is provided at one end of the sliding rod, a lifting rod is slidably arranged in the circular hole, a thin baffle is fixed below the lifting rod, and the thin baffle is located directly above one of the placement slots, and a locking assembly for fixing the sliding rod is provided at the upper end of the fixed tube.

[0009] The locking assembly includes an electromagnet, which is fixed to the upper end of the fixed tube. The sliding rod is made of iron material, and the lower surface of the electromagnet is in contact with the upper surface of the sliding rod. A push switch for turning the electromagnet on and off is installed on the sliding rod. A retaining ring is fixed to the upper end of the lifting rod, and the retaining ring is located above the push switch.

[0010] With the above structure, when the thin baffle is pulled downward, the retaining ring will squeeze the press switch downward, causing the electromagnet to be energized and adsorb the sliding rod. At this time, the sliding rod will be fixed under the action of friction, thereby preventing the thin baffle from moving horizontally. When the operator places the components subsequently, he will not accidentally touch the previously placed components. The operation is more convenient and can effectively improve work efficiency.

[0011] A copper bottom sheet is provided at the bottom of the placement slot, an electric heater is provided on the bottom plate, and the electric heater is fitted to the lower surface of the copper bottom sheet at a corresponding position.

[0012] With the above structure, after manual patching is completed, the operator can lift the thin baffle upwards, then rotate the patch board and move the other placement slot to the front to continue patching. At this time, the PCB circuit board after patching will be rotated above the electric heater, and the copper base plate at the bottom will be heated by the electric heater, thereby melting the solder and flux to achieve welding of the PCB circuit board.

[0013] A lifting block is slidingly provided inside the fixed tube, a thrust spring is provided at the bottom of the lifting block, a long slot is provided on the side wall of the fixed tube, a pressure rod is provided on the outside of the fixed tube, and a connecting rod is connected between the pressure rod and the lifting block, and the connecting rod passes through the long slot, and an iron sheet is fixed to the upper end of the pressure rod.

[0014] With the above structure, when the thin baffle is lowered to abut against the PCB circuit board, the electromagnet is in the energized state. At this time, the electromagnet will attract the iron sheet downward and fit it on the electromagnet, so that the bottom of the pressure rod abuts against the upper surface of the patch board, limiting the rotation of the patch board and preventing the operator from rotating the patch board when the thin baffle is not lifted, causing the placed components to be messed up again, further facilitating the operator's operation.

[0015] An anti-slip pad is fixed to the bottom of the pressure rod.

[0016] With the above structure, when in use, the friction between the anti-slip pad and the patch board is relatively large, which can further improve the stability of the patch board.

[0017] A soft rubber strip is fixed below the thin baffle.

[0018] With the above structure, when the thin baffle moves downward, the soft rubber strip can fit on the PCB circuit board, preventing the lower edge of the thin baffle from scratching the PCB circuit board, thereby achieving a protective effect.

[0019] Compared with the existing technology, this tire pressure sensor patch device has the following advantages:

[0020] 1. Through the thin baffle, sliding rod, lifting rod, fixing tube, patch board and locking assembly, the placed components can be separated at any time through the thin baffle to prevent accidental touch when placing components later, which will cause the previously placed components to need to be rearranged, making manual patching simpler and more convenient, and can effectively improve work efficiency.

[0021] 2. Through the electric heater, the components can be soldered after the patch is completed, without the need to transfer the PCB circuit board, which can further prevent the components from shifting and improve the accuracy of the soldering position.

[0022] 3. Through the pressure rod, lifting block, iron sheet and electromagnet, the patch board can be pressed tightly when the operator is performing patching to prevent it from rotating, thereby improving the patch accuracy. It can also prevent the operator from rotating the patch board without lifting the thin baffle, causing the placed components to be messed up again. BRIEF DESCRIPTION OF THE DRAWINGS
