Description

Technical Field

[0001] This invention relates to the field of liquid level sensor processing technology, specifically a liquid level sensor processing device. Background Technology

[0002] The working principle of a liquid level sensor is that when two pressures of the measured medium are introduced into the high and low pressure chambers, they act on the diaphragms on both sides of the element (i.e., the sensing element), and are transmitted to both sides of the measuring diaphragm through the diaphragms and the filling liquid inside the element. Therefore, liquid level sensors often have a cylindrical metal head connected to the data cable. Since the metal head needs to be immersed in water for a long time, it needs to be waterproofed.

[0003] However, the metal head at the front end of the liquid level sensor is relatively small. When painting it separately, a robotic arm is needed to hold and rotate it, which makes the entire device more complex and the manufacturing cost higher. Therefore, it is necessary to design painting equipment specifically for the processing of liquid level sensors. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In one embodiment, see Figures 1-8 A liquid level sensor processing device includes a base 1, a feeding mechanism 2 and a material handling mechanism 3;

[0029] The feeding mechanism 2 includes a rotatable conveyor belt 6 located on the left side of the base 1. The conveyor belt 6, which can rotate clockwise, is positioned on the left side of the upper surface of the base 1. Both ends of the conveyor belt 6 are connected to forward and backward oriented transmission rollers 5. The forward and backward ends of the transmission rollers 5 are rotatably connected to the upper end of a first support plate 4. The lower end of the first support plate 4 is fixedly connected to the left side of the upper surface of the base 1. A first drive motor 9 is mounted on the first support plate 4. The output shaft of the first drive motor 9 is fixedly connected to a first bevel gear 8. The first bevel gear 8 meshes with a second bevel gear 7. The second bevel gear 7 is fixedly connected to the front end of the transmission roller 5. Therefore, the first drive motor 9 can drive the transmission roller 5 via gear transmission. The moving roller 5 rotates clockwise, causing the conveyor belt 6 to rotate clockwise. A first column 10 is set at the left side of the base 1, and first columns 10 are also set on the front and rear sides of the base 1. The upper end of the first column 10 is fixedly connected to the first guide plate 11. The first guide plate 11 is set to the lower right. The left end of the first guide plate 11 is attached to the right side of the conveyor belt 6, so the material on the conveyor belt 6 can roll freely onto the first guide plate 11. A retaining edge 12 is set at the right end of the first guide plate 11. The retaining edge 12 is set perpendicular to the first guide plate 11, so the material will be blocked by the retaining edge 12 after sliding down to the right side with the first guide plate 11.

[0030] The material handling mechanism 3 includes a second support plate 14 fixedly connected to the base 1. The second support plate 14 is vertically positioned at the right-hand side of the center of the upper surface of the base 1. The upper end of the second support plate 14 is rotatably connected to a main shaft 15 facing forward and backward. The front and rear ends of the main shaft 15 are fixedly connected to the center of a rotating U-shaped frame 19. A second column 20 is positioned on the right side of the second support plate 14. The upper end of the second column 20 is fixedly connected to a second guide plate 21. The second guide plate 21 is tilted downward and to the right, and its lower right end is horizontal, thus forming an L-shape. After the rotating U-shaped frame 19 rotates counterclockwise, the rotating U-shaped frame... The left end of frame 19 is located below the right end of the first guide plate 11, and when the U-shaped frame 19 rotates counterclockwise, the maximum height of the right end of the U-shaped frame 19 will be lower than the right end of the second guide plate 21. At the same time, a painting assembly 29 is set on the right side of the second column 20 to process the metal head of the liquid level sensor. Meanwhile, a third column 13 is set on the right end of the upper surface of the base 1, and a support plate 30 is set on the upper end of the third column 13. The support plate 30 is tilted to the lower right, and the left end of the support plate 30 is located directly below the right end of the second guide plate 21. The height of the support plate 30 is lower than the lowest height of the U-shaped frame 19 after it rotates clockwise.

[0031] In one embodiment, a U-shaped groove is provided above the rotating U-shaped frame 19, and rounded edges are provided on the left and right sides of the bottom of the U-shaped groove and on the left and right ends of the outer side of the rotating U-shaped frame 19. Therefore, when the rotating U-shaped frame 19 rotates counterclockwise, the left end of the rotating U-shaped frame 19 pushes the material of the first guide plate 11 to the upper left. When the rotating U-shaped frame 19 intersects with the second guide plate 21, the right side of the U-shaped groove of the rotating U-shaped frame 19 is an arc surface. At this time, the material on the left side of the arc surface will be squeezed out by the second guide plate 21, so that the material slides to the right along with the second guide plate 21.

[0032] In one embodiment, the painting assembly 29 includes a support block 23 fixedly connected to the side of the second column 20. The rear support block 23 is fixedly connected to a third drive motor 22, the output shaft of which faces forward and is fixedly connected to a rotating disk 24. A support frame 25 is provided at the right end of the rear support block 23, and a spray nozzle 26 is provided on the left side of the support frame 25. The spray nozzle 26 can paint the metal head. A cylinder 27 is provided on the front support block 23, and the piston rod of the cylinder 27 faces backward. The end of the piston rod of the cylinder 27 is connected to a pressure plate 28. Therefore, after the piston rod of the cylinder 27 extends, the pressure plate 28 moves backward and pushes the metal head at the right end of the rotating U-shaped frame 19 to move backward and press against the rotating disk 24. At this time, when the third drive motor 22 drives the rotating disk 24 to rotate, the metal head will achieve a self-rotation effect. At this time, the spray nozzle 26 can effectively paint the entire outer surface of the metal head.

[0033] In one embodiment, a second drive motor 16 is mounted on the second support plate 14. The output shaft of the second drive motor 16 is fixedly connected to a third bevel gear 17, which meshes with a fourth bevel gear 18. The fourth bevel gear 18 is fixedly connected to the main shaft 15. The second drive motor 16 can effectively drive the main shaft 15 to rotate, thereby causing the rotating U-shaped frame 19 to rotate.

[0034] In this embodiment, the device is placed at the output end of the metal head production device of the liquid level sensor. The metal head that has completed the initial processing can fall freely to the left end of the conveyor belt 6, so that the metal head moves to the right with the conveyor belt 6 for painting. The first drive motor 9 is started, and the output shaft of the first drive motor 9 causes the conveyor belt 6 to rotate clockwise through gear transmission. The metal head moves to the right with the conveyor belt 6. After the metal head moves to the first guide plate 11, the metal head will move to the right end with the first guide plate 11 and be blocked by the baffle.

[0035] The second drive motor 16 is started. The output shaft of the second drive motor 16 causes the rotating U-shaped frame 19 to rotate via gear transmission. After the rotating U-shaped frame 19 rotates counterclockwise, its left end rotates to below the right end of the first guide plate 11. When the rotating U-shaped frame 19 rotates clockwise again, its left end lifts the metal head at the right end of the first guide plate 11, causing a metal head to fall onto the left end of the rotating U-shaped frame 19. When the rotating U-shaped frame 19 rotates clockwise to a horizontal position and continues to rotate, the metal head slides to the right with the rotating U-shaped frame 19. However, at this time, the height of the metal head is lower than that of the second guide plate 11. The material plate 21 is located at the left end, so the metal will not be stuck by the second guide plate 21 when it moves to the right. The second drive motor 16 stops when the rotating U-shaped frame 19 rotates clockwise to the right and faces downwards and backwards. At this time, the cylinder 27 is started and the piston rod of the cylinder 27 extends, which causes the pressure plate 28 to move backwards. The pressure plate 28 pushes the metal head to move backwards and press against the rotating disk 24. At this time, the third drive motor 22 is started and drives the rotating disk 24 to rotate. The rotating disk 24 will drive the metal head to rotate. At this time, the spray nozzle 26 sprays paint onto the surface of the metal head, so that the entire surface of the metal head is effectively painted.

[0036] After the metal head finishes painting, the rotating U-shaped frame 19 is rotated counterclockwise again. When the rotating U-shaped frame 19 rotates to a horizontal position and then to the lower left, the metal head will first move to the left with the rotating U-shaped frame 19. When the metal head moves to contact the second guide plate 21, the rotating U-shaped frame 19 continues to rotate counterclockwise, pushing the metal head to the upper left of the second guide plate 21. When the metal head is pushed to a height higher than the rotating U-shaped frame 19, it will pass the right end of the rotating U-shaped frame 19. At this time, the metal head will roll to the lower right with the second guide plate 21. Since the lower end of the second guide plate 21 is flat, the metal head will follow a parabolic trajectory after leaving the right end of the second guide plate 21. At this time, the metal head will fall onto the tray 30. After the rotating U-shaped frame 19 rotates to the lower left, it can grab the next metal head for painting.

[0037] This invention relates to a liquid level sensor processing device. By rotating the U-shaped frame 19 in both directions, the metal heads on the first guide plate 11 are picked up one by one for painting. The entire device only requires controlling the rotation of the U-shaped frame 19 to pick up the metal heads. The structure of the entire processing device is simpler than that of a robotic arm, and the manufacturing cost is greatly reduced.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
