Description

Technical Field

[0001] The present invention relates to the technical field of component picking, and in particular to a fully automatic component picking device. Background Art

[0002] With the continuous advancement and development of science and technology, electronic products are also constantly updated, which leads to a large number of electronic products being eliminated every year. However, these eliminated electronic products are not completely eliminated. Some of their components can still be used. Decomposing, recycling or reusing these electronic components can not only save production resources, but also avoid the generation of electronic waste. In the process of recycling electronic components, they need to be classified according to different types to facilitate subsequent reuse.

[0003] In the prior art, automatic picking equipment generally uses an image collector to capture images of components, then uses a computer to identify the types of components, and then controls a robot or other transfer machinery based on the identification results to classify the components. However, there are many types of components, and directly using an image collector for identification requires the ability to identify a particularly large number of types, which increases the probability of incorrect picking.

After the components are identified by the image collector, the magnetic force of the electromagnet is controlled to control the position of the magnetic block, and then the position of the piston is controlled, and finally the direction of the guide hopper is controlled, so that the components sent out from the conveying tube fall into different packaging barrels according to the direction of the guide hopper, thereby completing automatic picking, so that automatic picking can be operated on a production line, greatly improving the picking efficiency;

[0022] 3. By setting the blocking component, the conveying speed of the components conveyed through the conveying tube is reduced after contacting the blocking component, while the speed of the components passing through the blocking component is also increased, so that the components in the conveying tube can pass through the image collector one by one and at a certain distance, thereby ensuring accurate identification and picking, and avoiding two components passing through the image collector at the same time to affect identification;

[0023] 4. By setting the speed control component, when the components pass through the baffle and rotate, the baffle rotates slowly, ensuring that the components pass through the baffle slowly, and after the components pass through, the baffle quickly resets, avoiding the subsequent components from passing through the baffle 33 too quickly, ensuring that the components pass through the image acquisition stably one by one;

[0024] 5. Picking is performed by controlling the position of the magnetic block by controlling the magnetic force of the electromagnet, and then controlling the direction of the guide hopper. This is easier to control than picking by a robot or other machine. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] Reference Figure 1-10 A fully automatic component picking device comprises a base 1, a plurality of vertical plates 2 are fixedly connected to the upper surface of the base 1, a screening plate 3 is fixedly connected to the vertical plates 2, a plurality of feed hoppers 11 are fixedly connected to the lower surface of the screening plate 3, a conveying pipe 12 is fixedly connected to the lower surface of the feed hopper 11, and an opening 29 (such as Figure 5 shown);

[0037] A preliminary screening mechanism is provided on the screening plate 3, which is used to perform preliminary screening of components according to their sizes;

[0038] The base 1 is provided with a plurality of secondary screening mechanisms, which are composed of a detection control assembly and a guide control assembly. The detection control assembly is used to perform different controls according to different components. The detection control assembly is arranged on the base 1. The guide control assembly is used to guide the components to different directions according to the control of the detection control assembly. The guide control assembly is arranged at the conveying pipe 12. The detection control assembly includes a sliding sleeve 14. The side wall of the sliding sleeve 14 is penetrated and fixedly connected with a connecting pipe 15 (such as Figure 4 shown);

[0039] A deceleration mechanism is provided at the conveying pipe 12 , and the deceleration mechanism consists of a blocking component and a speed control component. The blocking component is used to decelerate the falling components, and the speed control component is used to control the blocking component. Both the blocking component and the speed control component are arranged in the conveying pipe 12 .

[0040] The preliminary screening mechanism includes two rollers 4, which are rotatably connected to the corresponding vertical plates 2 through bearings. A servo motor 5 is fixedly connected to the side wall of one of the vertical plates 2 through a bracket. One of the rollers 4 is fixedly connected to the output shaft of the servo motor 5. The rollers 4 are tensioned with two drive belts 6. A plurality of push plates 7 are fixedly connected between the two drive belts 6. The push plates 7 are slidably connected to the upper surface of the screening plate 3. The screening plate 3 is provided with a plurality of first sieve holes 8, second sieve holes 9, and third sieve holes 10. The components to be selected are placed on the screening plate 3, and the equipment is turned on. The servo motor 5 rotates to drive the rollers 4 to rotate, and the rollers 4 rotate The driving belt 6 is driven to rotate, and the rotation of the driving belt 6 drives the push plate 7 to move. The movement of the push plate 7 pushes the components on the screening plate 3 to pass through the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10. When the components pass through the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10, they will fall into the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10 according to different sizes. Through the push of the push plate 7, the components are first classified according to size and then subsequently picked, which greatly reduces the types of subsequent image acquisition, thereby greatly reducing the wrong selection rate of picking, and at the same time can reduce the recognition time and improve efficiency.

[0041] The detection and control assembly also includes a mounting post 13, one end of which is fixedly connected to the upper surface of the base 1, and the other end is fixedly connected to the lower surface of the sliding sleeve 14, a magnetic block 24 is sealed and slidably connected inside the sliding sleeve 14, a fixing plate 22 is fixedly connected between two opposite inner side walls of the sliding sleeve 14, and a plurality of first springs 25 (such as Fig.10 As shown in the figure, the side wall of the fixed plate 22 close to the magnetic block 24 is fixedly connected with an electromagnet 23, and the electromagnet 23 can generate magnetic force on the magnetic block 24 when it is energized. The inner wall of the opening 29 is fixedly connected with an image collector 30, and the image collector 30 is connected to the electromagnet 23 through a PLC control circuit. The image collector 30 can collect images passing through the components and identify them through the computer of the PLC control circuit. According to the identification result, the magnetic force of the electromagnet 23 is controlled, and the control of the magnetic force of the electromagnet 23 can control the position of the magnetic block 24.

[0042] The guide control mechanism includes a fixed column 16, the delivery pipe 12 is fixedly connected to the fixed column 16, the fixed column 16 is provided with an annular groove 17, the end of the connecting pipe 15 away from the sliding sleeve 14 is fixedly connected to the fixed column 16, the connecting pipe 15 connects the annular groove 17 with the inside of the sliding sleeve 14, and the inner wall of the annular groove 17 is rotatably connected to an annular plate 18 (such as Figure 7 As shown, a piston 19 is sealingly and slidably connected in the annular groove 17, and the piston 19 is fixedly connected to the lower surface of the annular plate 18. A partition plate 26 (as shown in FIG. 2 ) is fixedly connected to the inner wall of the annular groove 17. Fig.10As shown in the figure, the partition plate 26 is sealed and slidably connected to the lower surface of the annular plate 18, the upper surface of the annular plate 18 is fixedly connected to the connecting rod 20, and the end of the connecting rod 20 away from the annular plate 18 is fixedly connected to the guide hopper 21, the sliding sleeve 14, the connecting pipe 15, and the annular groove 17 are all filled with hydraulic oil, and the annular groove 17 is located between the piston 19 and the partition plate 26 and is close to the connecting pipe 15. The side wall of the fixed column 16 is provided with a hole (such as Fig.10 As shown), the part between the piston 19 and the partition 26 without the connecting pipe 15 is connected to the outside world, so that the piston 19 with a sealed sliding connection can slide freely in the annular groove 17, and the components that fall one by one continue to slide down. When passing through the image collector 30, the image collector 30 identifies the components and controls the magnetic force of the electromagnet 23 according to the identification result, which will control the magnetic repulsion of the electromagnet 23 on the magnetic block 24, so that the position of the magnetic block 24 changes. The change in the position of the magnetic block 24 will change the amount of hydraulic oil pumped into the annular groove 17, thereby controlling the position of the piston 19. The change in the position of the piston 19 will drive the annular plate 18 to rotate, and the annular plate 18 controls the direction of the guide hopper 21 through the connecting rod 20. After the components are identified, they fall out of the conveying pipe 12 and fall on the guide hopper 21. According to the direction of the guide hopper 21, they slide in different directions. The picking is carried out by changing the direction of the guide hopper 21, so that the picking process can be carried out in an assembly line, which greatly improves the picking efficiency.

[0043] It is worth mentioning that the present invention collects images through the image collector 30, and controls the magnetic force of the electromagnet 23 after identification, and finally controls the direction of the guide hopper 21 to complete the screening. Compared with the prior art through manipulators or other machines, the required structural components are simpler. At the same time, since other machines such as manipulators require a set of complex control programs to control, the program required for the picking method of the present invention is also simpler, thereby greatly reducing the equipment cost.

[0044] The blocking assembly includes two side plates 31 (such as Fig. 9 As shown in the figure, the side plate 31 is fixedly connected to the inner bottom wall of the opening 29, and a rotating rod 32 is fixedly connected between the two side plates 31. The rotating rod 32 is rotatably connected to a baffle 33 through a bearing. The baffle 33 blocks the component so that the speed is reduced after it contacts the baffle 33, and the descending speed is restored after it passes over the baffle 33, so that the distance between the two components is increased and they fall one by one, so that the components pass through the image collector 30 regularly one by one, avoiding missed recognition due to two components passing at the same time, and ensuring the accuracy of the recognition result.

[0045] The speed control assembly includes a function block 34, which is fixedly connected between the two side plates 31. The function block 34 is provided with a main slot 35 and a secondary slot 36 (such as Figure 5As shown in the figure, the main groove 35 and the auxiliary groove 36 are symmetrically arranged, the function block 34 is sealed and slidably connected with the top block 37 through the main groove 35, the function block 34 is sealed and slidably connected with the slider 38 through the auxiliary groove 36, a plurality of second springs 41 are fixedly connected between the top block 37 and the function block 34, the function block 34 is provided with an entry hole 39 and a reflux hole 40, the entry hole 39 and the reflux hole 40 connect the main groove 35 with the auxiliary groove 36, the main groove 35, the auxiliary groove 36, the entry hole 39, and the reflux hole 40 are all filled with hydraulic oil, after the components fall into the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10, they fall into the conveying pipe 12 through the feed hopper 11, the components enter the conveying pipe 12, and fall down along the conveying pipe 12, when the components contact the baffle 33, the components push the baffle 33 to rotate, and the baffle 33 pushes the top block 37 to move, so that the top block 37 moves into the main groove 35, and pumps the hydraulic oil into the auxiliary groove 36 through the inlet hole 39. Since the aperture of the inlet hole 39 is small, the hydraulic oil has a large entry resistance, so that the component moves slowly after contacting the baffle 33. After the component passes over the baffle 33, the baffle 33 is lost and the component falls faster. The top block 37 is reset under the elastic force of the second spring 41, and the hydraulic oil flows back from the auxiliary groove 36 into the main groove 35 through the reflux hole 40. The reflux hole 40 has a large aperture, so that the reflux resistance is small. The top block 37 will drive the baffle 33 to reset quickly and block the next component, ensuring that after the component passes through the baffle 33, the baffle 33 can be quickly reset to block the next component, avoiding the subsequent components from passing through the baffle 33 too quickly, and ensuring that the components pass through the image acquisition stably one by one.

[0046] A plurality of dispensing barrels 28 are disposed on the upper surface of the base 1 , and the dispensing barrels 28 are used to contain different types of components.

[0047] The apertures of the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10 gradually increase (e.g. Figure 1 and Figure 2 As shown), the parts pass through the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10, and fall into the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10 according to their sizes, thereby screening the components according to their sizes.

[0048] Both the inlet hole 39 and the return hole 40 are provided with a one-way valve. The one-way valve in the inlet hole 39 only allows the hydraulic oil to enter the sub-groove 36 from the main groove 35, and the one-way valve in the return hole 40 only allows the hydraulic oil to enter the main groove 35 from the sub-groove 36. The aperture of the inlet hole 39 is smaller than the aperture of the return hole 40. Through the setting of the aperture, the hydraulic oil enters the sub-groove 36 from the main groove 35 with a larger entry pressure, while when the hydraulic oil enters the main groove 35 from the sub-groove 36, the entry pressure is smaller.

[0049] The inner wall of the conveying tube 12 is glued with a rubber pad, and the rubber pad inside the conveying tube 12 can increase the friction when the components pass through, thereby reducing the speed and avoiding the image collector 30 not having enough time to identify the components when the speed is too fast.

[0050] In the present invention, the components to be picked are placed on the screening plate 3, and the equipment is turned on. The servo motor 5 rotates to drive the roller 4 to rotate, and the rotation of the roller 4 drives the driving belt 6 to rotate. The rotation of the driving belt 6 drives the push plate 7 to move. The movement of the push plate 7 pushes the components on the screening plate 3 to pass through the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10. When the components pass through the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10, they will fall into the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10 according to different sizes.

[0051] After the components fall into the first sieve hole 8, the second sieve hole 9, and the third sieve hole 10, they fall into the conveying pipe 12 through the feed hopper 11. The components enter the conveying pipe 12 and fall along the conveying pipe 12. When the components contact the baffle 33, the components push the baffle 33 to rotate, and the baffle 33 pushes the top block 37 to move, so that the top block 37 moves into the main groove 35, and the hydraulic oil is pumped into the auxiliary groove 36 through the inlet hole 39. Since the aperture of the inlet hole 39 is small, the hydraulic oil entry resistance is large, so that the components move slowly after contacting the baffle 33, and the components move slowly in the main groove 35. After the component passes over the baffle 33, it loses the obstruction of the baffle 33 and the component accelerates to fall, while the top block 37 is reset under the elastic force of the second spring 41, and the hydraulic oil flows back from the auxiliary groove 36 into the main groove 35 through the reflux hole 40. The reflux hole 40 has a larger aperture, so that the reflux resistance is smaller, and the top block 37 will drive the baffle 33 to reset quickly to block the next component. Through the obstruction of the baffle 33, the speed of the component decreases after contacting the baffle 33, and after passing over the baffle 33, the descending speed is restored, so that the distance between the two components is pulled apart and they fall one by one.

[0052] The components that fall one by one continue to slide down. When they pass through the image collector 30, the image collector 30 identifies the components and controls the magnetic force of the electromagnet 23 according to the identification result. The control of the magnetic force of the electromagnet 23 will control the magnetic repulsion of the electromagnet 23 on the magnetic block 24, thereby changing the position of the magnetic block 24. The change in the position of the magnetic block 24 will change the amount of hydraulic oil pumped into the annular groove 17, thereby controlling the position of the piston 19. The change in the position of the piston 19 will drive the annular plate 18 to rotate, and the annular plate 18 controls the direction of the guide hopper 21 through the connecting rod 20.

[0053] After the components are identified, they fall out of the conveying tube 12 and onto the guide hopper 21. Depending on the orientation of the guide hopper 21, they fall into different packaging barrels 28, so that different types of components fall into different packaging barrels 28 for storage, thereby completing fully automatic component picking.
