Description

Technical Field

[0001] This utility model relates to the field of sensor processing technology, and in particular to a silicone coating device for preparing visual and tactile sensors. Background Technology

[0002] A visual-tactile sensor is a device that can simultaneously perceive visual and tactile information. It is mainly used in the field of robotics to help robots manipulate objects more accurately. Visual-tactile sensors are usually made of flexible materials and have embedded pressure sensing elements and imaging systems. They can capture various characteristics of objects such as shape, hardness, and texture. The manufacturing process involves coating with silicone.

[0003] For example, patent number CN215695270U discloses a silicone coating device for sensor processing, including a support leg, a support platform, a pulley, a sensor, a silicone support frame, and a silicone tube clamp. The support platform is positioned above the support leg, and the pulley is positioned on the upper side of the support platform. Sensor fixing plates are positioned on the front and rear sides of the pulley. A sensor fixing groove is provided inside one side of the sensor fixing plate, and sensors are installed in the two sensor fixing grooves. A second chassis and a first chassis are positioned behind the sensor fixing plate, with the second chassis located to one side of the first chassis. A rotary motor bracket is positioned on the upper side of the second chassis, and a rotary motor is installed in two holes in the rotary motor bracket. The beneficial effects are: improved silicone coating efficiency, reduced worker workload, and improved silicone coating quality, resulting in uniform and consistent silicone coverage on the sensor.

[0004] However, the limiting structure of existing silicone coating devices is relatively fixed, resulting in low versatility of the devices. The limiting structure cannot be flexibly adjusted and adapted according to the size of the workpiece to be processed. At the same time, its dust removal structure only removes dust by cleaning brushes and lacks the function of collecting dust. The dust that is swept off can easily fall back onto the workpiece surface, affecting the coating process. Utility Model Content

[0014] The beneficial effects of this utility model are:

[0015] 1. The silicone coating device for the fabrication of the visual-tactile sensor controls the rotation of the bidirectional lead screw to make the moving block slide along the inner side of the limiting frame, thereby driving the limiting strip to move on the surface of the conveyor belt. This makes the spacing of the limiting strips match the size of the workpiece to be processed, thus improving the versatility and flexibility of the device.

A filter box 12 is installed inside the dust collection bin 11. A fan 13 is installed on the left side of the dust collection bin 11, and a coating mechanism is installed on the right side of the dust collection bin 11. By rotating the knob, the bidirectional lead screw 5 is rotated, causing the moving block 6 to slide along the inner side of the limiting frame 4, which drives the limiting strip 7 to move on the surface of the conveyor belt 2, so that the spacing of the limiting strip 7 is adapted to the size of the workpiece to be processed. The surface of the workpiece is cleaned by the cleaning roller 9. The fan 13 works, and the airflow carries the swept dust from the suction pipe 10 into the dust collection bin 11. After being filtered by the filter box 12, the dust is collected in the filter box 12.

[0025] Please see Figures 1-4 In this embodiment, the upper end of the dust removal chamber 3 and the frame 1 are fixedly connected, the left side of the limiting frame 4 and the dust removal chamber 3 are fixedly connected, the front and rear ends of the bidirectional lead screw 5 are rotatably connected to the limiting frame 4, the front end of the bidirectional lead screw 5 extends to the outside of the limiting frame 4 and a knob is fixedly installed thereon, the moving block 6 and the limiting strip 7 are arranged symmetrically in front and behind, the upper end of the moving block 6 is slidably connected to the inner side of the limiting frame 4, the lower end of the moving block 6 is fixedly connected to the limiting strip 7, the limiting strip 7 and the upper end of the conveyor belt 2 are mutually adapted, the bidirectional lead screw 5 and the moving block 6 are threadedly connected, the bidirectional lead screw 5 is controlled to rotate by rotating the knob, so that the moving block 6 slides along the inner side of the limiting frame 4, and drives the limiting strip 7 to move on the surface of the conveyor belt 2, so that the spacing of the limiting strip 7 is mutually adapted to the size of the workpiece to be processed.

[0026] Please see Figures 2-5In this embodiment, the inner sides of the cleaning roller 9 and the dust collection chamber 3 are rotatably connected by a rotating shaft. A motor is fixedly installed on the front side of the dust collection chamber 3, and the output end of the motor extends to the inner side of the dust collection chamber 3 and is fixedly connected to the cleaning roller 9. The motor is used to drive the cleaning roller 9 to rotate. The lower end of the suction pipe 10 and the upper end of the dust collection chamber 11 are connected to each other. The input end of the fan 13 and the lower end of the dust collection chamber 11 are connected to each other through a pipe. The left and right sides of the filter box 12 are slidably connected to the inner side of the dust collection chamber 11. A filter screen is fixedly installed at the bottom of the filter box 12. A pull cover is fixedly installed on the rear side of the filter box 12 to the outer side of the dust collection chamber 11. The pull cover is sealed to the rear side of the dust collection chamber 11. A cavity is provided between the bottom of the filter box 12 and the bottom of the dust collection chamber 11. The coating mechanism includes a support frame 101. A silicone liquid tank 102 is fixedly installed on the front side of the upper end of the support frame 101. The upper end is connected to an air pressure pipe interface, and the lower end of the silicone liquid tank 102 is equipped with a silicone injection head. The lower end of the silicone injection head is equipped with a silicone liquid unfolding component. The workpiece is fed by the conveyor belt 2 and moves into the dust removal chamber 3. The cleaning roller 9 is rotated by the motor to clean the surface of the workpiece. The blower 13 operates to drive the airflow to carry the swept dust from the suction pipe 10 into the dust collection chamber 11. After being filtered by the filter screen at the bottom of the filter box 12, the dust is collected in the filter box 12. The filter box 12 can be pulled out of the dust collection chamber 11 by pulling the cover for easy cleaning. The dust-removed workpiece is moved to the outside of the dust removal chamber 3 by the conveyor belt 2. Air is introduced into the air pressure pipe interface to apply pressure to the silicone liquid tank 102, so that the silicone liquid tank 102, silicone injection head and silicone liquid unfolding component cooperate to realize the silicone coating process of the workpiece.

[0027] During operation, the double-acting screw 5 is rotated by turning the knob, causing the moving block 6 to slide along the inner side of the limiting frame 4, which in turn drives the limiting strip 7 to move on the surface of the conveyor belt 2. This ensures that the spacing of the limiting strip 7 matches the size of the workpiece to be processed. The workpiece is fed by the operation of the conveyor belt 2 and moves into the dust removal chamber 3. The cleaning roller 9 is rotated by the motor, which cleans the surface of the workpiece. The blower 13 operates, causing the airflow to carry the swept dust from the suction pipe 10 into the dust collection chamber 11. After being filtered by the filter screen at the bottom of the filter box 12, the dust is collected in the filter box 12. The workpiece after dust removal is moved to the outside of the dust removal chamber 3 by the conveyor belt 2, where the silicone coating process is performed on the workpiece by the coating mechanism.

[0028] Through the above steps, the bidirectional lead screw 5 is rotated by turning the knob, causing the moving block 6 to slide along the inner side of the limiting frame 4, which in turn drives the limiting strip 7 to move on the surface of the conveyor belt 2. This ensures that the spacing of the limiting strip 7 matches the size of the workpiece to be processed. The surface of the workpiece is cleaned by the cleaning roller 9, and the airflow from the blower 13 carries the swept dust from the suction pipe 10 into the dust collection chamber 11. After being filtered by the filter box 12, the dust is collected in the filter box 12. This solves the problems of the relatively fixed limiting structure of the silicone coating device, the low versatility of the device, and the lack of dust collection function in its dust removal structure.
