With the continuous advancement of automation technology, more and more manufacturers are adopting automated cleaning equipment to clean their workpieces.
[0003] In existing technology, cleaning equipment includes grippers and a cleaning tank. The cleaning tank stores cleaning fluid, and the grippers hold the workpiece and immerse it in the cleaning fluid for cleaning. To ensure the cleanliness of the workpiece after cleaning, air nozzles are usually installed around the grippers to blow air onto the workpiece held by the grippers. In existing technology, multiple air nozzles are circumferentially fixed around the grippers, requiring a large number of nozzles, which increases the cost of the cleaning equipment. In addition, the air blown onto the workpiece by the nozzles also has certain dead zones (some parts of the workpiece are not blown by the air), resulting in incomplete cleaning of the workpiece by the nozzles. Summary of the Invention

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a pneumatic gripper mechanism, including a support frame 1, a lifting drive assembly 2, a rotating drive assembly 3, a clamp 4, multiple cleaning components 5, and a turntable 6 with a first through hole 61. The lifting drive assembly 2 is mounted on the support frame 1, and the turntable 6 is rotatably mounted on the support frame 1; the output end of the lifting drive assembly 2 passes through the first through hole 61 and is connected to the clamp 4; The rotary drive assembly 3 is mounted on the support frame 1 and connected to the turntable 6, used to drive the turntable 6 to rotate; The cleaning assembly 5 includes a hanging plate 51 and a first air nozzle 52 and a second air nozzle 53 that are vertically spaced on the hanging plate 51. The hanging plate 51 is fixedly mounted on the turntable 6. The first air nozzle 52 and the second air nozzle 53 are both used to blow air onto the workpiece on the fixture 4. All the cleaning assemblies 5 are distributed circumferentially around the fixture 4.
[0021] The number of cleaning components 5 can be set according to actual needs, and multiple cleaning components 5 are arranged at intervals along the circumference of the turntable 6; the clamp 4 can fix the workpiece by means of magnetic attraction, vacuum adsorption, clamping, bolt fixing, etc., and the workpiece includes but is not limited to electrodes, workpieces, etc.; the rotary drive component 3 includes but is not limited to motors, gear components, etc., and the lifting drive component 2 includes but is not limited to pneumatic cylinders, hydraulic cylinders, linear motors, lead screw and nut components, etc.
[0022] Specifically, after the clamp 4 grips the workpiece, the lifting drive assembly 2 moves the clamp 4 downward, allowing the workpiece to be placed in the cleaning solution in the storage space for cleaning. After the workpiece is cleaned in the cleaning solution, the lifting drive assembly 2 moves the clamp 4 and the workpiece upward and out of the storage space. The first air nozzle 52 and the second air nozzle 53 both blow air towards the workpiece, and the rotation drive assembly 3 drives the turntable 6 to rotate. The cleaning assembly 5 rotates around the workpiece under the drive of the turntable 6, so that the first air nozzle 52 and the second air nozzle 53 blow air onto the workpiece from 360° without dead angles, ensuring the cleanliness of the workpiece by the cleaning assembly 5 and improving the blowing efficiency of the pneumatic gripper mechanism. In addition, each of the cleaning assemblies 5 includes a first air nozzle 52 and a second air nozzle 53 spaced apart in the vertical direction. The first air nozzle 52 can blow air towards the workpiece from above, and the second air nozzle 53 can blow air towards the workpiece from below, further improving the efficiency and accuracy of the pneumatic gripper mechanism in cleaning the workpiece. Furthermore, since the cleaning component 5 can rotate around the clamp 4, the number of cleaning components 5 can be set to be relatively small, reducing the cost of the pneumatic gripper mechanism.
[0023] In one embodiment, such as Figures 1 to 4 As shown, the support frame 1 includes a support plate 11, a plurality of first support blocks 12 and a plurality of balls 13, the turntable 6 is rotatably mounted on the support plate 11, and the lifting drive assembly 2 is mounted on the support plate 11; All the first support blocks 12 are installed on the support plate 11 at intervals around the turntable 6. The first support block 12 is also provided with a rolling groove, and the balls 13 are rolled in the rolling groove one by one. The turntable 6 is rotatably mounted on all the balls 13, which support the turntable 6.
[0024] The number of the ball bearings 13 and the first support block 12 can be set according to actual needs, and the number of both is equal; the lifting drive assembly 2 is installed on the top surface of the support plate 11, and the first support block 12 is installed on the bottom surface of the support plate 11.
[0025] In this embodiment, the ball bearing 13 can support the turntable 6 from the bottom, and the ball bearing 13 can roll in the groove during the rotation of the turntable 6. The turntable 6 and the ball bearing 13 have rolling friction, and the friction between the turntable 6 and the ball bearing 13 is small, which extends the service life of the pneumatic gripper mechanism and ensures the smoothness of the rotation of the turntable 6.
[0026] In one embodiment, such as Figures 1 to 4As shown, the support frame 1 also includes a plurality of second support blocks 14 and a plurality of limiting posts 15; the second support blocks 14 are installed on the support plate 11 at intervals around the turntable 6, and the limiting posts 15 are installed one-to-one on the second support blocks 14; all the limiting posts 15 abut against the side of the turntable 6.
[0027] The number of the limiting post 15 and the second support block 14 can be set according to actual needs, and the number of both is equal; the second support block 14 is installed on the bottom surface of the support plate 11.
[0028] In this embodiment, the limiting post 15 can limit the turntable 6 from all sides. During the rotation of the turntable 6, the turntable 6 will drive the limiting post 15 to rotate on the second support block 14. The turntable 6 and the limiting post 15 have rolling friction. The friction between the turntable 6 and the limiting post 15 is small, which extends the service life of the pneumatic gripper mechanism and further ensures the smoothness of the rotation of the turntable 6.
[0029] In one embodiment, such as Figure 2 and Figure 3 As shown, the rotary drive assembly 3 includes a motor 31 and a disc 32 mounted on the motor 31. The motor 31 is mounted on the support plate 11, and the disc 32 abuts against the side of the turntable 6. The motor 31 is used to drive the disc 32 to rotate, and the disc 32 drives the turntable 6 to rotate.
[0030] The motor 31 is located above the support plate 11, and the disc 32 is located below the support plate 11.
[0031] Specifically, the motor 31 drives the disc 32 to rotate, and the disc 32 can drive the turntable 6 to rotate through friction. In this embodiment, the rotary drive assembly 3 has a simple structure and low cost.
[0032] In one embodiment, the disk 32 is a first gear, and the side of the turntable 6 is provided with a first meshing tooth, which meshes with the first gear.
[0033] Specifically, the motor 31 drives the first gear to rotate, and the first gear drives the turntable 6 to rotate through the meshing teeth, thus ensuring the stability of the rotation drive assembly 3 in driving the turntable 6 to rotate.
[0034] In one embodiment, such as Figure 1 and Figure 6As shown, the lifting drive assembly 2 includes a lifting drive component 21, multiple guide rods 22 and multiple guide sleeves 23. The lifting drive component 21 is mounted on the support plate 11, and the output end of the lifting drive component 21 passes through the first through hole 61 and is connected to the clamp 4. All the guide sleeves 23 are mounted on the support plate 11, and all the guide rods 22 are fixedly connected to the clamp 4, with each guide rod 22 slidingly inserted into the inner hole of the guide sleeve 23.
[0035] The lifting drive component 21 includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, a linear motor 31, and a lead screw and nut assembly. The number of guide rods 22 and guide sleeves 23 can be set according to actual needs, and the number of guide rods 22 and guide sleeves 23 is equal. Furthermore, the guide sleeves 23 are circumferentially distributed around the first through hole 61.
[0036] Specifically, during the process of the lifting drive 21 driving the clamp 4 to move up and down, the guide rod 22 slides in the inner hole of the guide sleeve 23, ensuring the stability of the clamp 4 moving up and down.
[0037] In one embodiment, such as Figure 1 and 6 As shown, the pneumatic gripper mechanism also includes a mounting block 17, which is mounted on the output end of the lifting drive assembly 2, and the clamp 4 is mounted on the mounting block 17; the support frame 1 also includes a buffer 16, which is mounted on the support plate 11 and is used to buffer the mounting block 17.
[0038] The end of the buffer 16 may be made of silicone or soft rubber material; the buffer 16 is located above the mounting block 17.
[0039] Specifically, during the process of the lifting drive assembly 2 driving the mounting block 17 and the clamp 4 to move upward, the mounting block 17 abuts against the buffer 16, indicating that the mounting block 17 has moved to its limit position. The buffer 16 and the clamp 4 are in flexible contact, which reduces the impact force generated during the upward movement of the mounting block 17 and reduces the vibration of the lifting drive assembly 2 caused by rigid impact, thereby extending the service life of the pneumatic gripper mechanism.
[0040] In one embodiment, such as Figure 5 As shown, the first air nozzle 52 is located above the second air nozzle 53, the first air nozzle 52 extends diagonally downward, and the second air nozzle 53 extends diagonally upward.
[0041] The first air nozzle 52 can blow air diagonally downwards, and the second air nozzle 53 can blow air diagonally upwards. Both the first air nozzle 52 and the second air nozzle 53 blow air towards the workpiece, which increases the contact area between the gas and the workpiece, further improving the drying efficiency of the cleaning component 5 on the workpiece, and further improving the cleanliness of the workpiece after drying.
[0042] In one embodiment, such as Figure 7 As shown, the clamp 4 includes a clamping base 41 and a plurality of clamping blocks 42. The clamping base 41 is provided with a positioning hole 411 and a plurality of sliding grooves 412 arranged around the positioning hole 411. The clamping blocks 42 are slidably installed in the sliding grooves 412 in a one-to-one correspondence. The clamping blocks 42 are used to clamp the workpiece located in the positioning hole.
[0043] The clamping seat 41 is also provided with a control air passage. When high-pressure gas is input into the control air passage, multiple clamping blocks 42 move closer to each other and clamp the workpiece in the positioning hole 411. When the control air passage is depressurized, multiple clamping blocks 42 move away from each other, so that the clamping blocks 42 will release the workpiece in the positioning hole 411, and the worker or robot can take out the workpiece from the positioning hole.
[0044] Another embodiment of this utility model provides a cleaning device, including a cleaning tank (not shown in the figure) and the above-mentioned pneumatic gripper mechanism. The cleaning tank is provided with a liquid storage space for storing cleaning fluid, and the lifting drive component 2 is used to drive the clamp 4 into or out of the liquid storage space.
[0045] The cleaning tank is located directly below the pneumatic gripper mechanism, and the opening of the liquid storage space faces upward.
[0046] Specifically, after the clamp 4 grips the workpiece, the lifting drive assembly 2 moves the clamp 4 downward, allowing the workpiece to be placed in the cleaning solution in the storage space for cleaning. After the workpiece is cleaned in the cleaning solution, the lifting drive assembly 2 moves the clamp 4 and the workpiece upward and out of the storage space. The first air nozzle 52 and the second air nozzle 53 both blow air towards the workpiece, and the rotation drive assembly 3 drives the turntable 6 to rotate. The cleaning assembly 5 rotates around the workpiece, so that the first air nozzle 52 and the second air nozzle 53 blow air onto the workpiece from 360° without dead angles, ensuring the blowing efficiency of the gripper mechanism and ensuring that the workpiece can be cleaned by the cleaning assembly 5. In addition, each cleaning assembly 5 includes a first air nozzle 52 and a second air nozzle 53 spaced apart in the vertical direction. The first air nozzle 52 can blow air towards the workpiece from above, and the second air nozzle 53 can blow air towards the workpiece from below, further improving the efficiency and accuracy of the gripper mechanism in cleaning the workpiece. Furthermore, since the cleaning component 5 can rotate around the clamp 4, the number of cleaning components 5 can be set to be relatively small, reducing the cost of the pneumatic gripper mechanism.
[0047] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
