Description

Technical Field

[0001] This invention relates to the field of industrial robot technology, and in particular to a robot for the recycling and inspection of electronic components. Background Technology

[0002] As core equipment in automated production, industrial robots are gradually extending into the field of electronic component testing with the development of the electronic waste recycling industry. In particular, they are used for electrical performance testing of recycled circuit boards. By contacting the test points of the circuit board with a test pen, parameters such as resistance and capacitance are measured to determine whether the board can be reused, which has become a key link in resource recycling.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: In the operation and use of existing testing robots, the circuit board fixing and reagent cleaning are carried out in separate steps, which can easily affect the testing effect due to secondary pollution or reagent diffusion. Most existing ones use a single wiping method, which is difficult to cover the testing point area and forms obvious wiping blind spots. These unremoved residual reagents will form an insulating layer or electrochemical interference when the testing pen comes into contact with them, causing abnormal fluctuations in contact resistance. This can lead to deviations in the testing data or, in severe cases, misjudgments by the testing pen, misclassifying reusable circuit boards as scrap. This reduces resource recycling efficiency and increases unnecessary testing costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the robots used for recycling and testing electronic components in the prior art have the disadvantage of low efficiency in removing residues at the testing points.

[0015] Advantages of this invention:

[0016] In this invention, while the abutting plate of the pressing component securely clamps the side of the circuit board, the gear and rack transmission mechanism simultaneously drives the drip tube of the medicine storage component to move precisely above the detection point. The directional delivery of the medicine is achieved through valve control, which eliminates the time spent on equipment idleness and workstation switching in traditional step-by-step operations. It also avoids dust contamination that may occur when the circuit board is exposed to the air while waiting for the medicine to drip, as well as the risk of edge corrosion caused by the diffusion of the medicine due to static placement.

[0017] In the directional cleaning structure, the electric push rod below the inner plate drives the wiping component and the angled wiping component to move down synchronously. The arc-shaped cotton plate reciprocates through the gear and rack transmission driven by the motor. Its arc-shaped contour fits the edge of the detection point, covering the chemical residue in the main area. The cotton block of the angled wiping component extends naturally to the gap between the arc-shaped cotton plates and the recessed corners of the detection point through the cooperation of the driven rod and the spring in the inclined groove. This eliminates the cleaning blind spots left by traditional single-plane wiping or rotary wiping. Subsequently, the miniature fan of the drying component delivers airflow into the housing through the hose. Combined with the closed space formed by the sponge ring and the detection point, it accelerates the evaporation of the chemical, ensuring that there is no liquid residue on the surface of the detection point before the test pen contacts it. This ensures pure contact between the test pen and the detection point, fundamentally improving the stability and reliability of electrical performance testing. Attached Figure Description

A collar 63 is disposed at the output end of the cylinder 62. The collar 63 is connected to the cover 72 to facilitate the movement and adjustment of the position of the directional impurity removal structure 7.

[0037] The directional cleaning structure 7 includes four sets of flexible hoses 71 connected to the outside of the duct 83. Each set of hoses 71 is evenly spaced and connected to a corresponding housing 72. The housing 72 is frustoconical. An inner plate 74 is provided at the top of the wiping component 75, connecting to the inner wall of the housing 72. An electric actuator 77 is provided at the bottom of the inner plate 74, with its output end connected to the wiping component 75. The reciprocating component also includes a rectangular shell 754 at the output end of the electric actuator 77. A motor 751 is provided at the top of the rectangular shell 754, with its output end extending into the interior of the rectangular shell 754. A gear 752 is provided at the output end of the motor 751. A sliding connection is provided inside the rectangular shell 754. The rack 3 753 consists of four sets of rack 3 753, which are staggered and mesh with gear 2 752. One end of the rack 3 753 is provided with an extension plate 756. A rotating rod 2 757 is rotatably connected to one side of the extension plate 756. A spring 2 758 is provided between the rotating rod 2 757 and the extension plate 756. The rotating rod 2 757 is connected to the cotton board 755. The surface of the cotton board 755 has a slanted groove 761. A driven rod 762 is rotatably connected to one side of the slanted groove 761. A spring 3 763 is provided between the driven rod 762 and the slanted groove 761. The driven rod 762 is connected to the cotton block 764, eliminating the wiping blind spot. The angled layout is adapted to the residual dead corner at the edge of the detection point.

[0038] The air-drying assembly 8 includes a fixing plate 81 set at the bottom of the connecting plate 52. A micro fan 82 is set at the bottom of the fixing plate 81. The output end of the micro fan 82 is connected to an air duct 83. The air duct 83 is connected to four sets of flexible hoses 71. The sponge ring 73 and the detection point close to form a relatively closed space, which accelerates the airflow on the detection point and realizes the rapid air-drying of the drug residue.

[0039] Working principle: The staff places the recycled circuit boards on the tables on both sides of the frame 2, and then feeds the circuit boards on the tables through the corresponding windows of the frame 2 to the position between the pressing structures 4 by operating the feeding components or moving arms 1 on both sides of the frame 2. Since there are two sets of symmetrically distributed inside the moving arms 1, after the circuit board is placed in the middle of the pressing structure 4, it needs to be fixed. Through the feeding on both sides of the frame 2 and the symmetrically distributed pressing structures 4, the circuit boards can be quickly fed and positioned, providing a stable foundation for subsequent fixing and testing. The symmetrical layout can also adapt to the fixing requirements of circuit boards of different sizes.

[0040] Driven by a hydraulic rod 42 fixed inside a groove 41 on the surface of the frame 2, the hydraulic rod 42 moves the top plate 43 at the output end upward to a suitable position. This, in turn, causes the top plate 43 to move the vertical plate 44 at the top upward, pushing one end of the rotating plate 45 upward. The rotating plate 45 then drives the rotating rod 410 to rotate. A side plate 48 is rotatably connected to one side of the rotating rod 410 and is connected to the frame 2. The rotating rod 410 causes the spring 411 to twist and store power, thus... The other end of the rotating plate 45 drives the medicine storage component 46 and the pressure plate 47 to move downward. Since the pressure plate 47 is slidably connected to the pressure component 49, and the abutment plate 491 is lower than the bottom surface of the pressure plate 47, the abutment plate 491 first contacts the side of the circuit board and is squeezed. The abutment plate 491 is flush with the bottom surface of the pressure plate 47 and fixes the side of the circuit board. The automatic clamping of the circuit board is achieved by using the hydraulic rod 42. The contact of the abutment plate 491 can ensure a firm fixation and avoid damaging the edge of the circuit board.

[0041] The abutment plate 491 drives the rack 492 on one side to slide inward into the pressure plate 47. The rack 492 drives the slider 496 on one side to slide and connect with the inner wall of the pressure plate 47. The slider 496 drives the spring 497 to stretch and store force. The spring 497 is used to rebound and reset when the abutment plate 491 is no longer under force. Since the rack 492 is meshed with the gear 493, the rack 492 drives the rotating shaft 494 inside the gear 493 to rotate. The rotating shaft 494 is rotatably connected to the pressure plate 47. The gear 493 is meshed with the rack 495. The rotation of the gear 493 drives the rack 495 to move. The rack 495 slides and connects to the outside of the pressure plate 47. The rack 495 drives the drip tube 462 of the medicine storage component 46 connected at one end to the circuit. The device moves directly above the detection point on the circuit board. When the drip tube 462 moves to a position directly above the detection point, the valve on the surface of the drip tube 462 is opened, allowing the medicine inside the medicine storage box 461 to drip onto the detection point through the drip tube 462 to react and dissolve residues. This facilitates the subsequent contact of the test pen 54 with the detection point for electrical performance testing. A short tube is also connected to one side of the medicine storage box 461 for replenishing the medicine inside the medicine storage box 461, achieving synchronization between circuit board fixation and medicine dripping. The drip tube 462 moves above the detection point to ensure that the medicine acts directionally on the residues, avoiding waste and diffusion. The spring 497 reset structure ensures that the pressure component 49 can be reused, and the short tube design facilitates medicine replenishment, improving continuous operation capability.

[0042] Once the circuit board is fixed and the reagents have dripped onto the corresponding detection points, the operator activates the moving arm 1. The driving source at each joint of the moving arm 1 drives the detection component 5, moving assembly 6, directional cleaning structure 7, and drying assembly 8 at the end of the moving arm 1 to move in a designated direction until they approach the detection point. A connecting frame 51 is located at the end of the moving arm 1, and a connecting plate 52 is located directly below the connecting frame 51. Multiple test pens 54 are positioned at the bottom of the connecting plate 52 corresponding to the circuit board detection points, and the directional cleaning structure 7 is positioned corresponding to each test pen 54. Cameras 53 are also positioned on both sides of the connecting frame 51. The cameras 53 monitor the movement of the moving arm 1 as the detection component 5 descends, dissolving the reagents and residues dripping onto the detection points during this time. The time difference during the movement allows for a full reaction between the reagents and residues. The cameras 53 monitor in real time to ensure the alignment of each component. The multiple test pens 54 correspond to the directional cleaning structure 7, allowing for simultaneous processing of multiple detection points and improving detection efficiency.

[0043] Because the directional cleaning structure 7 at the bottom of the connecting plate 52 is lower than the test head of the test pen 54, the reagent on the test point will be precisely cleaned and dried by the directional cleaning structure 7 before the test pen 54 contacts the test point. When the connecting plate 52 moves the moving component 6, the directional cleaning structure 7, and the drying component 8 closer to the test point, the cylinder 62 fixed at the bottom of the connecting plate 52 via the bottom connecting plate 61 is activated first. Multiple sets of cylinders 62 are evenly distributed, and the number of cylinders 62 is equal to the number of the cover 72 and the test pen 54. The cylinder 62 drives the output end to move the cover 72, which is fixed by the collar 63, to a position directly above the detection point. The drive of the cylinder 62 is paused. When the moving arm 1 is driven downward, it can drive the sponge ring 73 at the bottom of the cover 72 to contact the outer ring of the detection point. The sponge ring 73 can adsorb the reagent at the detection point. The directional impurity removal structure 7 contacts the detection point before the test pen 54. The sponge ring 73 pre-adsorbs the reagent on the outer ring to prevent the reagent from spreading to the contact area of ​​the test pen 54. Multiple sets of synchronous operation can adapt to the simultaneous processing needs of multiple detection points.

[0044] Because an inner plate 74 is provided inside the housing 72, and an electric push rod 77 is provided at the bottom of the inner plate 74, the wiping component 75 at the output end is moved downward by activating the electric push rod 77, so that the cotton board 755 and the cotton block 764 come into contact with the detection point. Then, the motor 751 is started to rotate clockwise and counterclockwise a few times. The motor 751 extends into the interior of the rectangular housing 754. The motor 751 drives the gear 2 752 at the output end to rotate. Because four sets of racks 3 753 are meshed on the outer side of the gear 2 752, and the four sets of racks 3 753 are staggered and all four sets of racks 3 753 are slidably connected to the rectangular housing 754, each of the four sets of racks 3 753 drives one end of the cotton board 755. The four sets of arc-shaped cotton plates 755 and arc-shaped cotton blocks 764 move back and forth to wipe and absorb the agent on the detection point. Since an extension plate 756 is provided on one side of the rack three 753, and a rotating rod two 757 is rotatably connected to one side of the extension plate 756, and a spring two 758 is provided at the top of the rotating rod two 757, the rotating rod two 757 is connected to the cotton plate 755, so that the cotton plate 755 always stays in contact when the rack three 753 drives the cotton plate 755 to move, realizing the reciprocating wiping of the cotton plate 755. The arc shape adapts to the shape of the detection point, improving the wiping coverage. The four sets of staggered cotton plates 755 can remove the agent and residue without dead corners, ensuring that the cotton plate 755 fits the detection point and avoids missed wiping.

[0045] Furthermore, a slanted groove 761 is provided on one side of the cotton board 755. A driven rod 762 is rotatably connected inside the slanted groove 761. The driven rod 762 is connected to the cotton block 764. A spring 763 is provided at the top of the driven rod 762. The cotton block 764 is at a certain angle to the cotton board 755. One end of the cotton block 764 extends to the outside of the cotton board 755. Therefore, the cotton block 764 can wipe and absorb the agent in the gap between two adjacent cotton boards 755. The slanted groove 761 and the driven rod 762 allow the cotton block 764 to penetrate into the gap between the cotton boards 755, eliminating the wiping blind spot. The angled layout is adapted to the residual dead corner at the edge of the detection point. The spring 763 ensures that the cotton block 764 always fits the detection point, further improving the agent removal effect and laying the foundation for the subsequent detection by the test pen 54.

[0046] After wiping, the micro fan 82, which is fixed by the fixing plate 81 at the bottom of the connecting plate 52, is driven. The air output by the micro fan 82 through the air duct 83 is split into four sets of hoses 71. The four sets of hoses 71 input the air into the interior of the corresponding connected cover 72, so that the sponge ring 73 contacts and closes with the detection point, allowing the air inside the cover 72 to quickly dry the detection point. The airflow generated by the micro fan 82 is directionally delivered to the cover 72 through the hoses 71. The sponge ring 73 closes with the detection point to form a relatively closed space, which accelerates the effect of the airflow on the detection point, realizes the rapid drying of the reagent residue, and avoids the residual liquid from affecting the electrical performance detection of the test pen 54.

[0047] Then, the electric push rod 77 is activated again to move the erasing component 75 and the oblique erasing component 76 upward. Then, the cylinder 62 is activated to move the cover 72 from directly above the detection point to one side, without obstructing the test pen 54. Subsequently, the driving moving arm 1 moves the test pen 54 downward to contact the detection point, so that the test pen 54 can perform electrical performance testing on the circuit board. The automatic retraction of the directional cleaning structure 7 avoids interference with the test pen 54, ensuring that the test pen 54 can accurately contact the detection point. The action sequence of each component is closely connected, reducing invalid waiting time and improving the detection efficiency of a single circuit board.

[0048] Furthermore, the servo motor 32 fixed inside the frame 2 can drive the worm gear 33 at the output end to rotate. The worm gear 33 is meshed with the worm wheel 34, which drives the rotating plate 31 at the top to rotate. The rotating plate 31 is fixedly connected to the moving arm 1, and the rotating plate 31 drives the moving arm 1 to turn, so that the frame 2 can automatically repeat the above operation to test the circuit board on the other side. The rotation of the moving arm 1 is achieved through the transmission structure of the worm gear 33 and the worm wheel 34. With the symmetrical layout on both sides of the frame 2, dual-station alternating testing can be achieved. Continuous testing of the circuit boards on both sides can be completed without manual intervention, which greatly improves the continuous operation capability of the equipment.

[0049] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
