Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensor production, in particular to a surface plating device for pressure sensor production. Background Art

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules. During the production and processing of the sensor, a plating device is required to plate the surface of the sensor to improve the mechanical properties of the sensor. However, some existing sensor plating devices can only plate a single sensor, resulting in low processing efficiency and inconvenience for factory batch processing.

[0003] For example, Chinese patent announcement number CN219377723U discloses a surface plating device for sensor production. When in use, the number of fixed cylinders is ten, which can achieve the effect of batch operation. The bottom end of the sensor is inserted into the installation groove, which can compress the spring. The reaction force of the spring is used to push the clamping plate, and the two sides of the bottom of the sensor are squeezed and fixed by the clamping plate, thereby ensuring the stability of the sensor. After the sensor is installed, the installation plate is clamped at the bottom of the mounting seat, and the electromagnet is turned on. The magnetic adsorption effect of the electromagnet on the adsorption metal plate can ensure the stability of the installation plate at the bottom of the mounting seat. The stepper motor is turned on, and the threaded screw is driven by the rotation of the output end of the stepper motor. The rotation of the threaded screw can drive the internal threaded sleeve to move downward, and the mounting seat is driven by the internal threaded sleeve. The mounting seat drives the installation plate through the mounting seat, and the installation plate moves downward until the sensor is immersed in the liquid material in the liquid material barrel. After the plating operation is completed, the stepper motor is turned on to reverse, and the installation plate is raised. Finally, the electric heating component is turned on to increase the temperature of the inner cavity of the processing box, accelerate the drying of the plating material on the surface of the sensor, and effectively improve the processing efficiency of the device.

[0004] However, the surface plating device for sensor production in the above application clamps the sensor inside the mounting groove and squeezes and fixes the sensor through a clamping plate, which results in that the clamping part cannot be well plated. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a surface plating device for pressure sensor production. Utility Model Content

[0006] The purpose of the utility model is to provide a surface plating device for pressure sensor production, so as to solve the problem that the surface plating device for sensor production proposed in the above-mentioned background technology clamps the sensor inside the installation groove and squeezes and fixes the sensor through a clamping plate, which will cause the clamping part to not be well plated.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a surface plating device for pressure sensor production, comprising a base and a support frame, the support frame is fixedly connected to the upper surface of the base, and a plating device and a drying device are arranged on the base.

[0008] The plating device comprises a plating unit and a cleaning unit.

The pressure sensor is placed inside the placement box, and then the electric lifting rod is driven to push the U-shaped frame and the placement box at the bottom thereof to move down into the plating liquid immersed in the interior of the plating box, so that multiple pressure sensors are plated to improve the processing efficiency.

[0010] A further improvement is that the vibration assembly includes a sleeve, an electromagnet, a vibration spring, and a magnetic slide bar.

When the pressure sensor is immersed in the plating liquid, the electromagnet is intermittently energized, thereby generating a repulsive force between the electromagnet and the magnetic slide bar, pushing the magnetic slide bar to slide along the sleeve to the bottom and stretching the vibration spring. When the electromagnet is powered off, the vibration spring resets under the action of its own elasticity, thereby pulling the magnetic slide bar to reset, thereby driving the placement box to vibrate up and down, thereby driving the pressure sensor inside it to vibrate up and down, so that its outer surface is fully immersed in plating.

[0011] A further improvement is that the cleaning unit includes a driving motor, a fixed bearing, a transmission member, a slider, and a cleaning box. The driving motor is installed at the top of the left outer surface of the support frame, and the two fixed bearings are respectively installed at the bottom of the left and right outer surfaces of the support frame.

[0013] A further improvement is that the drying device includes a drying box, a dryer, an air outlet duct, and a drying hood, the drying box being fixedly connected to the right side of the upper surface of the base, the dryer being installed at the rear end of the right side of the upper surface of the base, the air outlet duct being fixedly connected to the air outlet of the dryer, and the top end of the air outlet duct extending into the interior of the drying box, and the drying hood being fixedly connected to the top end of the air outlet duct.

[0014] A further improvement is that a feed trough is provided above the left outer surface of the drying box, and a slide groove is provided at the top center of the drying box. The placement box and the electric lifting rod pass through the feed trough and the slide groove respectively. The placement box is moved again so that it passes through the feed trough on the drying box and then falls into the interior of the drying box. The dryer is then started to blow hot air to the drying hood through the air outlet pipe, thereby drying the pressure sensor inside the placement box and improving the processing efficiency.

[0015] A further improvement is that a push-pull groove is provided at the bottom of the right outer surface of the drying box, and a water collecting box is slidably connected to the inside of the push-pull groove.
