Description

Technical Field

[0001] The present invention relates to the technical field of automatic feeding of electronic components, and particularly to a multi-station feeding device and method for the production of electronic components. Background Art

[0002] In order to improve production efficiency, reduce manual operation, lower costs, increase flexibility and adaptability, etc., most electronic components adopt a multi-station feeding method during production. Electronic components with different feeding requirements (such as clamping feeding or adsorption feeding) are set at different stations. Most mechanical arms with end effectors are arranged between multiple stations, and the mechanical arms complete the feeding work of the electronic components.

[0003] In the prior art, the end effector of the mechanical arm of some multi-station feeding devices has both an adsorption function and a clamping function, and feeds electronic components with different feeding requirements (such as clamping feeding or adsorption feeding). During the adsorption process, there may be impurities such as dust and oil stains on the surface of the components, and these impurities will adhere to the surface of the adsorption structure, affecting the adsorption effect. Therefore, it is necessary to clean the adsorption structure regularly. However, after the mechanical arm continuously alternates between clamping or adsorption feeding, when cleaning the adsorption structure of the mechanical arm at this time, the mechanical arm must be stopped, and the worker holds a cleaning cloth to clean the adsorption structure, which will interrupt the production process and lead to a decrease in production efficiency. Especially on a high-efficiency production line, the increase in downtime will directly affect the output. Workers need to approach the mechanical arm for cleaning. If safety measures are not in place, there may be potential safety hazards. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, the end effector of the mechanical arm of some multi-station feeding devices has both an adsorption function and a clamping function, and feeds electronic components with different feeding requirements (such as clamping feeding or adsorption feeding). During the adsorption process, there may be impurities such as dust and oil stains on the surface of the components, and these impurities will adhere to the surface of the adsorption structure, affecting the adsorption effect. Therefore, it is necessary to clean the adsorption structure regularly. However, after the mechanical arm continuously alternates between clamping or adsorption feeding, when cleaning the adsorption structure of the mechanical arm at this time, the mechanical arm must be stopped, and the worker holds a cleaning cloth to clean the adsorption structure, which will interrupt the production process and lead to a decrease in production efficiency. Especially on a high-efficiency production line, the increase in downtime will directly affect the output. Workers need to approach the mechanical arm for cleaning.

Workers sequentially feed the workpieces to be adsorbed and the workpieces to be clamped onto the loading conveyor belts on both sides of the workbench. S2. The six-degree-of-freedom robotic arm switches between the adsorption function and the clamping function, and continuously sends the workpieces to be adsorbed and the workpieces to be clamped. When the six-degree-of-freedom robotic arm is performing the clamping function, the adsorption component will be self-cleaned.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The main structure of the present invention includes a six-degree-of-freedom robotic arm and a fixed frame provided at its end. A free clamping component and an adsorption component are provided on the fixed frame. The free clamping component allows the clamping jaws to rotate freely while still being able to perform the clamping function. A control component and a wiping component are provided on the side of the fixed frame. The control component can drive the clamping component to perform the clamping function each time, and at the same time, control the wiping component to automatically wipe and clean the adsorption component. The whole process does not require the robotic arm to stop, without additional downtime, reducing production interruptions caused by cleaning, improving production efficiency. Workers do not need to approach the robotic arm for cleaning. The automated cleaning process can keep the adsorption component cleaner more frequently and effectively, reducing equipment failures and maintenance requirements caused by adsorption surface contamination, thereby reducing maintenance costs.

[0016] 2. An extended-range driving component is provided on the side of the fixed frame of the present invention. The extended-range driving component can transfer the small displacement in the vertical direction of the control component to the wiping component, and the wiping component finally makes a large displacement in the horizontal direction, so that the wiping component moves above the adsorption component for cleaning. The extended-range driving component adopts the principle of a gear and a rack. Compared with the lever principle, it can achieve the long-distance movement of the wiping component without increasing the stroke of the control component, improving the space utilization efficiency, making the whole system structure more compact, reducing the need for additional space, saving space, and being suitable for installation in the limited space of the end effector of the robotic arm.

[0017] 3. The core component of the wiping assembly provided in the present invention is a section of cleaning cloth. One end of the cleaning cloth is wound around the winding roller, and the other end is wound around the outer wall of the releasing roller. A follow-up storage assembly is provided on the side of the wiping assembly. When the follow-up storage assembly controls the transverse movement of the wiping assembly under the control of the extended-range driving assembly, the follow-up storage assembly can release a section of brand-new cleaning cloth and store the soiled cleaning cloth. Through the follow-up storage assembly, new cleaning cloth can be continuously released while the used soiled cloth is stored. In this way, the wiping assembly can always use fresh cleaning cloth for cleaning, extending the duration of a single cleaning process and reducing the frequency of cleaning cloth replacement. The follow-up storage assembly is linked with the wiping assembly to automatically release and store the cleaning cloth without manual intervention, improving the automation level and reducing the labor intensity of the operator.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0033] Referring to Figure 1-12 , a multi-station feeding device for electronic component production, includes a working frame 3 and a six-degree-of-freedom robotic arm 1. A six-degree-of-freedom robotic arm 1 is fixedly arranged at the middle position on the top of the working frame 3. The six-degree-of-freedom robotic arm 1 is a general manipulator in the prior art. Loading conveyor belts 2 are arranged on both sides of the six-degree-of-freedom robotic arm 1 on the top of the working frame 3. One of the two loading conveyor belts 2 is used to send electronic components with adsorption characteristics to the feeding position of the robotic arm, and the other is used to send electronic components with clamping characteristics to the feeding position of the robotic arm. A fixed frame 4 is fixedly arranged at the output end of the six-degree-of-freedom robotic arm 1. A dual-mode loading component is arranged on the front side of the fixed frame 4, allowing the output end of the six-degree-of-freedom robotic arm 1 to have two functions of adsorption or clamping. The dual-mode loading component includes a free clamping component and an adsorption component.

[0034] The free clamping assembly includes clamping jaws 18, a rotating motor 11, and a guiding block 14. The adsorption assembly includes a vacuum suction nozzle 51 and a top cross seat 5. A receiving box 6 is fixedly arranged at the top of the fixed frame 4. A top cross seat 5 is fixedly arranged at the top of the side of the fixed frame 4. Four vacuum suction nozzles 51 are equidistantly arranged at the top of the top cross seat 5. A wiping assembly is arranged inside the receiving box 6. The wiping assembly can wipe the four vacuum suction nozzles 51 to prevent the vacuum suction nozzles 51 from failing. A control assembly is arranged on the side of the fixed frame 4. The control assembly can drive the clamping jaws of the free clamping assembly to open and close while rotating. An extended drive assembly is arranged above the drive assembly on the fixed frame 4. The extended drive assembly can transmit a small displacement in the vertical direction of the control assembly to the wiping assembly, driving the wiping assembly to clean the adsorption assembly immediately.

[0035] An installation plate 10 is fixedly arranged below the fixed frame 4 on the same side as the top cross seat 5. An avoidance groove 9 is formed at the top of the installation plate 10. A rotating motor 11 is fixedly arranged at the top of the installation plate 10. The output end of the rotating motor 11 is fixedly provided with a guiding block 14. A lifting block 13 is movably inserted above the guiding block 14 at the output end of the rotating motor 11. Transverse movement grooves 141 are formed at the tops of the lifting block 13 and the guiding block 14. An installation groove 142 is formed on the side of the guiding block 14. A rectangular block 17 is slidably connected inside the installation groove 142. The rectangular block 17 is fixedly connected to the side of the clamping jaw 18. An inclined groove 15 is formed at the top of the side of the clamping jaw 18. Driving columns 16 are symmetrically and fixedly arranged on the side of the lifting block 13. The inclined groove 15 and the driving columns 16 have the same width, and the outer walls of the driving columns 16 and the inner walls of the inclined groove 15 are polished into smooth surfaces.

[0036] The driving columns 16 extend into the inclined groove 15. When the lifting block 13 moves vertically, the driving columns 16 arranged on the side of the lifting block 13 will move along the inclined groove 15, thereby pushing the two clamping jaws 18 closer to or away from each other. The arrangement of the rectangular block 17 and the installation groove 142 restricts the two clamping jaws 18 to only displace in the horizontal direction. Anti-slip protrusions 181 are equidistantly arranged on the sides of the two clamping jaws 18 in the vertical direction to increase the friction between the clamping jaws 18 and the electronic components to be clamped.

[0037] The drive assembly includes a pushing ring 12, a drive fork 28, and a vertical rod 23. The pushing ring 12 is fixedly connected to the top of the lifting block 13. The drive fork 28 is movably inserted into the pushing ring 12 in the horizontal direction. A weight reduction groove 27 is formed at the top of the drive fork 28. A horizontal block 24 is fixedly arranged on the side of the drive fork 28. A vertical rod 23 is fixedly arranged at the top of the horizontal block 24. A fixed block 25 is fixedly arranged on the side of the vertical rod 23. The bottom of the fixed block 25 is fixedly connected to the output end of the micro electric push rod 26. The micro electric push rod 26 is fixedly connected to the top of the installation plate 10. When the micro electric push rod 26 expands and contracts to drive the vertical rod 23 to move upward, the drive fork 28 will lift the lifting block 13 through the pushing ring 12.

[0038] The wiping assembly includes a U-shaped frame 34, a winding roller 39, a releasing roller 37, a cleaning cloth 38, and a follow-up storage assembly. The side of the U-shaped frame 34 is sequentially rotatably connected with a winding roller 39 and a releasing roller 37. One end of the cleaning cloth 38 is adhered to the outer wall of the winding roller 39, and the other end of the cleaning cloth 38 is adhered to the outer wall of the releasing roller 37. A damping ring 35 is fixedly arranged on the outer walls of the rotating shafts of the winding roller 39 and the releasing roller 37 of the U-shaped frame 34. A damping bolt 36 is screwed into the top of the damping ring 35. By closely contacting the rotating shafts of the winding roller 39 and the releasing roller 37, the damping bolt 36 applies a certain resistance to the rotation of the winding roller 39 and the releasing roller 37, so that the winding roller 39 winds one end of the cleaning cloth 38, the releasing roller 37 winds one end of the cleaning cloth 38, and the cleaning cloth 38 remains taut throughout the process.

[0039] The follow-up storage assembly includes a one-way bearing 30, a storage gear 29, a storage rack 33, and a guide plate 7. The end of the rotating shaft of the winding roller 39 is fixedly connected to the inner ring of the one-way bearing 30. The outer ring of the one-way bearing 30 is welded with a storage gear 29. A vertical groove 330 is formed on the side of the storage rack 33. A stepped block 32 is movably inserted into the vertical groove 330. The stepped block 32 is fixedly connected to the side of the U-shaped frame 34. An elastic column 31 is fixedly connected to the top of the stepped block 32. The top of the elastic column 31 is fixedly connected to the top of the vertical groove 330. The storage rack 33 is stably meshed with the storage gear 29. A guide plate 7 is fixedly arranged on the side of the storage box 6. A guide inclined surface 71 is formed on the top of the guide plate 7. The bottom of the storage rack 33 is attached to the guide inclined surface 71. The bottom of the storage rack 33 is polished into a smooth surface. The range-increasing drive assembly includes an input rack 22, a driving gear 20, a driven gear 19, and an output rack 21. The driving gear 20 is rotatably connected to the side of the fixed frame 4. The driven gear 19 is fixedly connected concentrically with the driving gear 20. The input rack 22 is vertically and stably meshed with the side of the driving gear 20. The input rack 22 is fixedly connected to the top of the side of the vertical rod 23. The number of teeth of the driving gear 20 is less than that of the driven gear 19. The output rack 21 is horizontally and stably meshed with the bottom of the driven gear 19.

[0040] A limiting horizontal groove 210 is formed on the side of the output rack 21. A T-shaped block 211 is movably inserted into the limiting horizontal groove 210. The other end of the T-shaped block 211 is fixedly connected to the side of the auxiliary vertical plate 8. The auxiliary vertical plate 8 is fixedly arranged on the side of the fixed frame 4. The top of the side of the output rack 21 is fixedly connected to the bottom end of an inverted U-shaped rod 40. A docking crank 41 is screwed into the top of the side of the inverted U-shaped rod 40. A guide groove 61 is formed on the side of the storage box 6. After passing through the guide groove 61, the docking crank 41 is screwed into the side of the U-shaped frame 34. A limiting horizontal groove 210 is formed on the side of the output rack 21. A T-shaped block 211 is movably inserted into the limiting horizontal groove 210.

[0041] The other end of the T-shaped block 211 is fixedly connected to the side surface of the auxiliary vertical plate 8, the auxiliary vertical plate 8 is fixedly arranged on the side surface of the fixed frame 4, the top of the side surface of the output tooth bar 21 is fixedly connected to the bottom end of the inverted U-shaped rod 40, a docking crank 41 is screwed into the top of the side surface of the inverted U-shaped rod 40, a guide groove 61 is formed in the side surface of the accommodating box 6, and after the docking crank 41 passes through the guide groove 61, it is screwed into the side surface of the U-shaped frame 34. One end of the U-shaped frame 34 is inserted into the inside of the guide groove 61. When the docking crank 41 is unscrewed from the side surface of the U-shaped frame 34, the wiping assembly arranged on the U-shaped frame 34 can be disassembled, so that it is convenient for workers to maintain and clean the wiping assembly.

[0042] The installation direction of the one-way bearing 30 needs to be properly installed so that when the bottom of the receiving tooth bar 33 moves from the bottom to the top along the bottom of the guiding inclined surface 71, the winding roller 39 can be driven to wind the cleaning cloth 38 through the receiving gear 29 and the one-way bearing 30. When the bottom of the receiving tooth bar 33 moves from the top to the bottom along the top of the guiding inclined surface 71, after the elastic column 31 resets, the receiving gear 29 cannot drive the winding roller 39 to rotate through the one-way bearing 30.

[0043] The specific implementation steps and principles of the present invention are as follows: When the six-degree-of-freedom robotic arm 1 controls the free clamping assembly to perform the clamping operation, a plurality of vacuum suction nozzles 51 are vertically upward, and two clamping claws 18 are vertically downward. The micro electric push rod 26 is controlled to start. The micro electric push rod 26 drives the lifting block 13 to move up or down through the driving fork 28 and the pushing ring 12, and drives the two clamping claws 18 to approach or move away from each other through the driving column 16 and the inclined groove 15. At the same time, the vertical rod 23 drives the output tooth bar 21 to move horizontally through the input tooth bar 22, the driving gear 20 and the driven gear 19. Since the driving gear 20 and the driven gear 19 are concentrically and fixedly arranged, and the number of teeth of the driving gear 20 is less than that of the driven gear 19, when the vertical rod 23 has a small displacement in the vertical direction, the U-shaped frame 34 directly connected to the output tooth bar 21 drives the wiping assembly to approach the tops of the four vacuum suction nozzles 51. During this process, when the bottom of the receiving tooth bar 33 moves from the bottom to the top along the bottom of the guiding inclined surface 71, the winding roller 39 can be driven to wind the cleaning cloth 38 through the receiving gear 29 and the one-way bearing 30, and the cleaning cloth 38 wipes the four vacuum suction nozzles 51.

[0044] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
