[0002] A force sensor is a device that can sense external force and convert it into electrical signal output. It is usually composed of elastic elements, resistance strain gauges and other auxiliary components. Painting the surface of the force sensor can protect the sensor surface and improve its corrosion resistance, wear resistance and aesthetics.

[0003] On the one hand, when fixing the sensor, the operation is often complicated, and it is difficult to fix the sensor in the appropriate position quickly and accurately. Moreover, due to the fixing jig, the jig may block the position that needs to be painted, resulting in the need for secondary repainting of the blocked position later, and the production efficiency is relatively low. For this reason, it is necessary to provide a force-sensitive sensor surface painting device, which adopts an internal support clamping positioning method to achieve fast and easy positioning, ensure that the sensor is stable and does not block the paint surface during the painting process, thereby ensuring uniform painting and improving production efficiency and product quality.

DETAILED DESCRIPTION

[0022] Hereinafter, an embodiment of the force-sensitive sensor surface painting device of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 The force-sensitive sensor surface painting device of an embodiment of the present invention is shown, comprising a workbench 1: a positioning fixture 2 is fixedly installed on the front side of the top of the workbench 1, a paint spraying assembly 3 is provided on the rear side of the top of the workbench 1, and the paint spraying assembly 3 comprises a paint sprayer 31 fixedly installed on the rear side of the top of the workbench 1, a propulsion device 32 is fixedly installed on the top of the paint sprayer 31, and the output end of the propulsion device 32 is fixedly connected to a paint spraying rack 33, and a nozzle 34 is fixedly installed on the front side of the top and bottom of the inner cavity of the paint spraying rack 33. The liquid outlet of the paint sprayer 31 is connected to the workbench 1 through a hose, and a protective cover 35 is fixedly installed on the front side of the top of the workbench 1. The protective cover 35 is set on the surface of the positioning fixture 2 and the paint spraying rack 33. Through the setting of the paint spraying assembly 3, the paint sprayer 31, the hose and the nozzle 34 are used in conjunction to atomize and spray the paint liquid. At the same time, through the cooperation of the propulsion device 32 and the paint spraying rack 33, the upper and lower surfaces of the sensor are sprayed with paint at the same time, thereby improving the painting efficiency and avoiding the need to flip the sensor to receive the paint liquid. The positioning fixture 2 Both sides of the top are fixedly connected with a fixed tube 4, the top of the fixed tube 4 is fixedly connected with a shell 5, the inner cavity of the shell 5 is provided with an inner support assembly 6, the inner support assembly 6 includes three inner support clamps 61 distributed in an annular manner in the inner cavity of the shell 5, the outer surface of the inner support clamp 61 is set to an arc shape, and the surface of the shell 5 is provided with three arc-shaped openings 65 adapted to the inner support clamp 61. The top and bottom of the inner cavity of the shell 5 are fixedly connected with three limit blocks 7, and the top and bottom of the inner support clamp 61 are provided with a space adapted to the limit block 7. The matching limiting groove 8, through the coordinated use of the limiting block 7 and the limiting groove 8, plays a limiting and guiding role on the inner support clamp 61, thereby improving the stability of the inner support clamp 61 during the sliding process. The inner cavity of the fixed tube 4 is fixedly installed with an electric telescopic rod 62, and the output end of the electric telescopic rod 62 is fixedly connected to the lifting head 63. The surface of the lifting head 63 is annularly distributed with three connecting parts 64, one end of the connecting part 64 is rotatably connected to the lifting head 63, and the other end of the connecting part 64 is rotatably connected to the inner support clamp 61.

[0024] Working principle: When using the present invention, the user first places the sensor on the top of the positioning fixture 2 so that the shell 5 penetrates into the interior of the sensor. Then the electric telescopic rod 62 is opened and the lifting head 63 is pulled downward. The lifting head 63 squeezes the three connecting parts 64 during the downward sliding process, causing the connecting parts 64 to rotate and push the inner support clamp 61. At this time, the three inner support clamps 61 move backward at the same time and contact the inner wall of the sensor, thereby achieving the inner support clamping and fixing of the sensor. Then, the paint sprayer 31 and the propulsion device 32 are turned on. The propulsion device 32 is pointed forward to the paint spray rack 33, so that the sensor is located in the inner cavity of the paint spray rack 33. At the same time, the paint sprayer 31 transports paint liquid to the nozzle 34 through a hose. The paint liquid is atomized and sprayed out under the action of the nozzle 34 and sprayed on the top and bottom of the sensor.

[0025] To sum up: the surface painting device of the force-sensitive sensor, through the coordinated use of the fixed tube 4, the outer shell 5 and the inner support component 6, performs internal support clamping and positioning of the sensor, and then evenly sprays paint on its surface through the paint spray component 3, thereby achieving the purpose of quick and easy positioning and uniform painting without flipping.
