Description

Technical Field

[0001] This invention belongs to the field of circuit board cleaning technology, and in particular relates to a cleaning mechanism. Background Technology

[0002] Before inserting electronic components, SMT (Surface Mount Technology) circuit boards need to be cleaned; otherwise, the production quality of the inserted electronic components will be affected, and the performance of the circuit board will be compromised.

[0003] Cleaning mechanisms typically include friction rollers, which are positioned above the circuit board transport track. These rollers remove particles, dust, and other foreign matter from the circuit board surface as it is transported. Current cleaning mechanisms are usually motor-driven, with their position adjusted according to the circuit board thickness. This results in a fixed distance between the friction rollers and the transport track, which cannot accommodate variations in circuit board thickness that can cause board jamming. This can lead to circuit board damage and compromised quality. Summary of the Invention

[0048] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention 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 invention and are not intended to limit the invention.

[0049] like Figures 1 to 9 As shown, an embodiment of the present invention provides a cleaning mechanism, including a first fixed base 9, a second fixed base 10 and a first cleaning component, wherein the first cleaning component is connected between the first fixed base 9 and the second fixed base 10.

[0050] The first cleaning assembly includes a friction roller 5, a first support base 1, a second support base 2, a first floating assembly 3 connected to the first support base 1, and a second floating assembly 4 connected to the second support base 2. The first support base 1 is fixedly mounted on a first fixed base 9, and the second support base 2 is fixedly mounted on a second fixed base 10. The friction roller 5 is used to remove foreign matter from the surface of the board to be cleaned during transport.

[0051] The first end of the friction roller 5 is slidably connected to the first support base 1. The first floating component 3 applies an elastic support force to the first end of the friction roller 5, enabling the first end of the friction roller 5 to slide on the first support base 1, thereby allowing the first end of the friction roller 5 to float up and down. The second end of the friction roller 5 is slidably connected to the second support base 2. The second floating component 4 applies an elastic support force to the second end of the friction roller 5, enabling the second end of the friction roller 5 to slide on the second support base 2, thereby allowing the second end of the friction roller 5 to float up and down, thus achieving the floating of the friction roller 5.

[0052] The cleaning mechanism provided in this embodiment of the invention has a first floating component 3 and a second floating component 4 that can apply an elastic support force to the friction roller 5. The direction of the elastic support force is opposite to the direction of the gravity of the friction roller 5. The friction roller 5 can abut against the plate to be cleaned on the transport track. When the thickness of the plate has a deviation, the elastic support force and the reverse force of the plate on the friction roller 5 can overcome the gravity of the friction roller 5 itself, so that the friction roller 5 can float upward. The distance between the friction roller 5 and the transport track changes, which can adapt to the thickness deviation of the plate, avoid the problem of plate jamming and plate damage, and improve the pass rate and quality of the plate.

[0053] In one embodiment, such as Figure 1 As shown, the friction roller 5 is a rubber roller. The friction roller 5 is located above the transport track. When the board is transported to the bottom of the friction roller 5, the friction roller 5 presses against the board, thereby adsorbing the dirt on the surface of the board and achieving the purpose of cleaning.

[0054] In one embodiment, such as Figure 3 As shown, the first floating component 3 includes a first floating pin 31 and a first elastic element 32. The first elastic element 32 is sleeved on one end of the first floating pin 31, and the other end of the first floating pin 31 abuts against the first end of the friction roller 5. The first end of the friction roller 5 can squeeze the first floating pin 31, thereby causing the first elastic element 32 to be squeezed and compressed, generating an elastic support force acting on the friction roller 5.

[0055] like Figure 4 As shown, the second floating component 4 includes a second floating pin 41 and a second elastic member 42. The second elastic member 42 is sleeved on one end of the second floating pin 41, and the other end of the second floating pin 41 abuts against the second end of the friction roller 5. The second end of the friction roller 5 can squeeze the second floating pin 41, thereby causing the second elastic member 42 to be squeezed and compressed, generating an elastic support force acting on the friction roller 5.

[0056] Understandably, when the friction roller 5 presses against the plate, under the reaction force of the plate on the friction roller 5, the first floating component 3 applies an elastic support force to the first end of the friction roller 5 and the second floating component 4 applies an elastic support force to the second end of the friction roller 5 simultaneously, thereby overcoming the weight of the friction roller 5 and enabling the friction roller 5 to float upward.

[0057] In one embodiment, the first elastic element 32 and the second elastic element 42 are configured to generate elastic deformation and recover deformation, preferably, the first elastic element 32 and the second elastic element 42 are springs.

[0058] In one embodiment, such as Figure 7 As shown, the first floating pin 31 includes a first pin 311, a second pin 312, and a third pin 313. The first pin 311 and the third pin 313 are respectively connected to the two axial ends of the second pin 312. The cross-sectional area of ​​the second pin 312 is larger than the cross-sectional areas of the first pin 311 and the third pin 313. The cross-section refers to the section perpendicular to the axial direction. The end of the first pin 311 away from the second pin 312 abuts against the first end of the friction roller 5. The first elastic member 32 is sleeved on the outside of the third pin 313 and abuts against the second pin 312. The axial length of the first elastic member 32 is greater than the axial length of the third pin 313. When the first pin 311 is squeezed by the friction roller 5, the second pin 312 squeezes the first elastic member 32, and the first elastic member 32 can be compressed and generate an elastic support force.

[0059] like Figure 8 As shown, the second floating pin 41 includes a fourth pin 411, a fifth pin 412, and a sixth pin 413. The fifth pin 412 is connected between the fourth pin 411 and the sixth pin 413. The fourth pin 411 and the sixth pin 413 are located at the two axial ends of the fifth pin 412. The cross-sectional area of ​​the fifth pin 412 is larger than that of the fourth pin 411 and the sixth pin 413. The end of the fourth pin 411 away from the fifth pin 412 abuts against the second end of the friction roller 5. The second elastic member 42 is sleeved on the outside of the sixth pin 413 and abuts against the fifth pin 412. The axial length of the second elastic member 42 is greater than that of the sixth pin 413. When the fourth pin 411 is squeezed by the friction roller 5, the fifth pin 412 squeezes the second elastic member 42, and the second elastic member 42 can be compressed and generate an elastic support force.

[0060] In one embodiment, such as Figure 5 , Figure 7As shown, the first support base 1 includes a first support portion 11 and a first sliding connection portion 12 connected above the first support portion 11. The friction roller 5 is provided with a first bearing 51 and a second bearing 52. The first sliding connection portion 12 is provided with a first guide groove 121. The first bearing 51 is disposed in the first guide groove 121 and can move along the first guide groove 121. The first support portion 11 is provided with a first mounting hole 111, which communicates with the first guide groove 121. The first floating component 3 is disposed in the first mounting hole 111, and one end of the first floating component 3 extends into the first guide groove 121 and abuts against the first bearing 51.

[0061] like Figure 7 As shown, the first guide groove 121 is a U-shaped groove, and the first bearing 51 is disposed in the U-shaped groove. The outer peripheral surface of the first bearing 51 abuts against the side wall of the first guide groove 121. The first mounting hole 111 extends downward from the bottom surface of the first guide groove 121 and passes through the first support part 11. In the axial direction of the friction roller 5, the width of the first guide groove 121 is smaller than the width of the first sliding connection part 12. The position of the first bearing 51 is restricted by the first guide groove 121 to prevent the first bearing 51 from disengaging from the first floating pin 31 and to prevent the friction roller 5 from moving axially and deviating.

[0062] In one embodiment, such as Figure 7 As shown, the first elastic element 32 is disposed in the first mounting hole 111, one end of the first floating pin 31 is disposed in the first mounting hole 111 and connected to the first elastic element 32, and the end of the first floating pin 31 away from the first elastic element 32 extends into the first guide groove 121.

[0063] On the first floating pin 31, the first pin 311, the second pin 312, and the third pin 313 are all cylindrical structures. The first mounting hole 111 includes a first hole and a second hole that are interconnected. The inner diameter of the first hole is smaller than the inner diameter of the second hole, forming a stepped hole. The second pin 312 and the third pin 313 are disposed in the second hole. The inner diameter of the second hole matches the outer diameter of the second pin 312. The first elastic element 32 is sleeved on the third pin 313, which facilitates the second pin 312 to squeeze the first elastic element 32. One end of the first pin 311 is disposed in the second hole, and the other end of the first pin 311 passes through the first hole and extends into the first guide groove 121. The inner diameter of the first hole matches the outer diameter of the first pin 311. This allows the end face of the second pin 312 near the first pin 311 to abut against the junction of the first hole and the second hole when the first pin 311 is not squeezed by the friction roller 5, thus providing a stop and preventing the first floating pin 31 from popping out of the first mounting hole 111.

[0064] In one embodiment, such as Figure 8As shown, the second support base 2 includes a second support portion 21 and a second sliding connection portion 22 connected above the second support portion 21. The second sliding connection portion 22 is provided with a second guide groove 221. The second bearing 52 can move along the second guide groove 221. The second bearing 52 is disposed in the second guide groove 221. The second mounting hole 211 communicates with the second guide groove 221. The second support portion 21 is provided with the second mounting hole 211. The second floating component 4 is disposed in the second mounting hole 211. One end of the second floating component 4 extends into the second guide groove 221 and abuts against the second bearing 52.

[0065] like Figure 8 As shown, the second guide groove 221 is a U-shaped groove, and the second bearing 52 is disposed in the U-shaped groove. The outer peripheral surface of the second bearing 52 abuts against the side wall of the second guide groove 221. The second mounting hole 211 passes through the second support part 21 from the bottom surface of the second guide groove 221 downwards. In the axial direction of the friction roller 5, the width of the second guide groove 221 is smaller than the width of the second sliding connection part 22. The second guide groove 221 restricts the position of the second bearing 52, preventing the second bearing 52 from disengaging from the second floating pin 41 and preventing the friction roller 5 from moving axially and deviating. The first sliding connection part 12 and the second sliding connection part 22 restrict the axial movement of the friction roller 5, preventing the friction roller 5 from shifting.

[0066] In one embodiment, such as Figure 8 As shown, the second elastic element 42 is disposed in the second mounting hole 211, one end of the second floating pin 41 is disposed in the second mounting hole 211 and connected to the second elastic element 42, and the end of the second floating pin 41 away from the second elastic element 42 extends into the second guide groove 221.

[0067] On the second floating pin 41, the fourth pin 411, the fifth pin 412, and the sixth pin 413 are all cylindrical structures. The second mounting hole 211 includes a third hole and a fourth hole that are interconnected. The inner diameter of the third hole is smaller than the inner diameter of the fourth hole, forming a stepped hole. The fifth pin 412 and the sixth pin 413 are disposed in the fourth hole. The inner diameter of the fourth hole matches the outer diameter of the fifth pin 412. The second elastic element 42 is sleeved on the sixth pin 413, which facilitates the fifth pin 412 to compress the second elastic element 42. One end of the fourth pin 411 is set in the fourth hole, and the other end of the fourth pin 411 passes through the third hole and extends into the second guide groove 221. The inner diameter of the third hole matches the outer diameter of the fourth pin 411. This allows the end face of the fifth pin 412 near the fourth pin 411 to abut against the junction of the third hole and the fourth hole when the fourth pin 411 is not squeezed by the friction roller 5, thus providing a stop and preventing the second floating pin 41 from popping out of the second mounting hole 211.

[0068] In one embodiment, the first bearing 51 and the second bearing 52 are self-aligning ball bearings.

[0069] In one embodiment, such as Figure 5 , Figure 7 As shown, a first connecting plate 13 is mounted on the side of the first support portion 11 away from the first sliding connection portion 12, and the other end of the first floating component 3 abuts against the first connecting plate 13. The first connecting plate 13 is provided with a first through hole 131 and a second through hole 132 that communicate with each other. The inner diameter of the first through hole 131 is larger than the inner diameter of the second through hole 132. The end of the first elastic member 32 away from the first floating pin 31 is disposed in the first through hole 131, and the first elastic member 32 is disposed between the second pin 312 and the second through hole 132. When the first elastic member 32 is compressed by the first floating pin 31, the first elastic member 32 abuts against the interface between the first through hole 131 and the second through hole 132. Preferably, the inner diameter of the first through hole 131 is the same as the inner diameter of the second hole of the first mounting hole 111.

[0070] In one embodiment, such as Figure 8 As shown, a second connecting plate 23 is installed on the side of the second support portion 21 away from the second sliding connection portion 22, and the other end of the second floating component 4 abuts against the second connecting plate 23. The second connecting plate 23 is provided with a third through hole 231 and a fourth through hole 232 that communicate with each other. The inner diameter of the third through hole 231 is larger than the inner diameter of the fourth through hole 232. The end of the second elastic member 42 away from the second floating pin 41 is disposed in the third through hole 231. The second elastic member 42 is disposed between the fifth pin 412 and the fourth through hole 232. When the second elastic member 42 is pressed by the second floating pin 41, the second elastic member 42 abuts against the interface between the third through hole 231 and the fourth through hole 232. Preferably, the inner diameter of the third through hole 231 is the same as the inner diameter of the fourth hole of the second mounting hole 211.

[0071] In one embodiment, such as Figure 2 As shown, the cleaning mechanism further includes a first lifting component 6 for adjusting the position of the first end of the friction roller 5 and a second lifting component 7 for adjusting the position of the second end of the friction roller 5. The position of the friction roller 5 can be adjusted by the first lifting component 6 and the second lifting component 7. The position of the friction roller 5 is set according to the thickness of the plate to be cleaned. When there is a slight deviation in thickness between different plates, the thickness deviation is absorbed by the first floating component 3 and the second floating component 4.

[0072] like Figure 3 , Figure 5As shown, the first lifting assembly 6 includes a first lifting rod 61, a first lever adjustment member 62, and a first adjustment component 63. The first lever adjustment member 62 has a first rotating shaft in the middle, and the first lever adjustment member 62 can rotate around the first rotating shaft. The first adjustment component 63 is connected to one end of the first lever adjustment member 62, and the first lifting rod 61 is connected to the other end of the first lever adjustment member 62. The first rotating shaft forms the fulcrum of the first lever adjustment member 62. The first adjustment component 63 causes the lever to rotate, and the first lifting rod 61 hinders the rotation of the lever.

[0073] Specifically, the interior of the first floating pin 31 is a hollow structure. The first end of the first push rod 61 is connected to the other end of the first lever adjustment member 62. The second end of the first push rod 61 passes through the first connecting plate 13 and is inserted into the first floating pin 31. That is, the first push rod 61 passes through the second through hole 132, the first through hole 131, and the first elastic member 32 in sequence and is then inserted into the first floating pin 31.

[0074] The first adjusting component 63 can apply pressure to the first lever adjusting member 62 in a first direction. The first lever adjusting member 62 rotates around the first rotating axis and drives the first push rod 61 to move in a second direction, which is opposite to the first direction. The first direction is downward and the second direction is upward. The first adjusting component 63 applies downward pressure to the first lever adjusting member 62, and the first lever adjusting member 62 rotates clockwise, driving the first push rod 61 to move upward. The first push rod 61 can move within the hollow channel inside the first floating pin 31. It should be noted that the top end of the first push rod 61 cannot protrude beyond the top end of the first floating pin 31. When the first bearing 51 is not pressing on the first floating component 3, the first elastic member 32 is in a relaxed state, and there is a height difference between the top end of the first push rod 61 and the top end of the first floating pin 31. When the first bearing 51 presses on the first floating component 3, the first elastic member 32 is gradually compressed, and the height difference between the top end of the first push rod 61 and the top end of the first floating pin 31 gradually decreases. When the first push rod 61 touches the first bearing 51, the first elastic member 32 stops compressing. When cleaning the plates, the reaction force of the plates on the friction roller 5 and the elastic force of the first elastic element 32 push the friction roller 5 upward, thus achieving floating.

[0075] In one embodiment, such as Figure 4As shown, the second lifting assembly 7 includes a second lifting rod 71, a second lever adjustment member 72, and a second adjustment assembly 73. The second lever adjustment member 72 has a second rotating shaft in the middle, and the second lever adjustment member 72 can rotate around the second rotating shaft. The second adjustment assembly 73 is connected to one end of the second lever adjustment member 72, and the second lifting rod 71 is connected to the other end of the second lever adjustment member 72. The second rotating shaft forms the fulcrum of the second lever adjustment member 72. The second adjustment assembly 73 causes the lever to rotate, and the second lifting rod 71 hinders the rotation of the lever.

[0076] Furthermore, the interior of the second floating pin 41 is a hollow structure. The first end of the second push rod 71 is connected to the other end of the second lever adjustment member 72. The second end of the second push rod 71 passes through the second connecting plate 23 and is inserted into the second floating pin 41. That is, the second push rod 71 passes through the fourth through hole 232, the third through hole 231, and the second elastic member 42 in sequence and is then inserted into the second floating pin 41.

[0077] The second adjusting component 73 can apply pressure to the second lever adjusting member 72 in the first direction. The second lever adjusting member 72 rotates around the second rotation axis and drives the second push rod 71 to move in the second direction. The second adjusting component 73 applies downward pressure to the second lever adjusting member 72, and the second lever adjusting member 72 rotates counterclockwise, driving the second push rod 71 to move upward. The second push rod 71 can move within the hollow channel inside the second floating pin 41. It should be noted that the top end of the second push rod 71 cannot protrude beyond the top end of the second floating pin 41. When the second bearing 52 is not pressing on the second floating component 4, the second elastic member 42 is in a relaxed state, and there is a height difference between the top end of the second push rod 71 and the top end of the second floating pin 41. When the second bearing 52 presses on the second floating component 4, the second elastic member 42 is gradually compressed, and the height difference between the top end of the second push rod 71 and the top end of the second floating pin 41 gradually decreases. When the second push rod 71 touches the second bearing 52, the second elastic member 42 stops compressing. When cleaning the plates, the reaction force of the plates on the friction roller 5 and the elastic force of the second elastic element 42 push the friction roller 5 upward, thus achieving floating.

[0078] It is understandable that the first adjustment component 63 acts on the first lever adjustment component 62 and the second adjustment component 73 acts on the second lever adjustment component 72 simultaneously, ensuring that the first push rod 61 and the second push rod 71 move upward at the same distance, so that the friction roller 5 remains horizontal and does not tilt.

[0079] In one embodiment, such as Figure 3 , Figure 5As shown, the first adjustment assembly 63 includes a first drive wheel 631, a first threaded rod 632, and a first screw support 633. The first screw support 633 is mounted on the first fixed seat 9. The first drive wheel 631 is connected to the first threaded rod 632, and the first threaded rod 632 is threadedly connected to the first screw support 633. The first threaded rod 632 has an external thread, and the first screw support 633 has a threaded hole with an internal thread. The first threaded rod 632 passes through and is threadedly connected to the threaded hole. Under the drive of the power mechanism, the first drive wheel 631 can rotate, and the first threaded rod 632 rotates with the first drive wheel 631. Through the threaded connection between the first threaded rod 632 and the first screw support 633, the first threaded rod 632 can be driven to move up and down axially. When the first threaded rod 632 moves downward, it can apply pressure downward to the first lever adjustment member 62, causing the first lever adjustment member 62 to rotate clockwise, thereby driving the first push rod 61 to move upward.

[0080] like Figure 4 As shown, the second adjustment assembly 73 includes a second drive wheel 731, a second threaded rod 732, and a second screw support 733. The second screw support 733 is mounted on the second fixed base 10. The second drive wheel 731 is connected to the second threaded rod 732, and the second threaded rod 732 is threadedly connected to the second screw support 733. The second threaded rod 732 has an external thread, and the second screw support 733 has a threaded hole with an internal thread. The second threaded rod 732 passes through and is threaded into the threaded hole. Under the drive of the power mechanism, the second drive wheel 731 can rotate, and the second threaded rod 732 rotates with the second drive wheel 731. Through the threaded connection between the second threaded rod 732 and the second screw support 733, the second threaded rod 732 can be driven to move up and down axially. When the second threaded rod 732 moves downward, it can apply downward pressure to the second lever adjustment member 72, causing the second lever adjustment member 72 to rotate counterclockwise, thereby driving the second push rod 71 to move upward.

[0081] In one embodiment, such as Figure 9 As shown, the first lever adjustment member 62 includes a first push rod connecting part 621, a first screw connecting part 622, and a first rotating part 623 connected between the first push rod connecting part 621 and the first screw connecting part 622. The first rotating part 623 is rotatably connected to the first fixed seat 9 through a first connecting pin 6231. The first end of the first push rod 61 is engaged with the first push rod connecting part 621, and the end of the first threaded rod 632 away from the first drive wheel 631 is engaged with the first screw connecting part 622.

[0082] like Figure 4As shown, the second lever adjustment member 72 includes a second push rod connecting part 721, a second screw connecting part 722, and a second rotating part 723 connected between the second push rod connecting part 721 and the second screw connecting part 722. The second rotating part 723 is rotatably connected to the second fixed seat 10 through a second connecting pin 7231. The first end of the second push rod 71 is engaged with the second push rod connecting part 721, and the end of the second threaded rod 732 away from the second drive wheel 731 is engaged with the second screw connecting part 722.

[0083] In one embodiment, the first lever adjustment member 62 and the second lever adjustment member 72 have the same structure. The first push rod connection part 621 and the first screw connection part 622 are symmetrically connected on both sides of the first rotating part 623, and the second push rod connection part 721 and the second screw connection part 722 are symmetrically connected on both sides of the second rotating part 723.

[0084] like Figure 9 As shown, the first push rod connecting part 621 includes a first plate 6211 and a second plate 6212 arranged parallel to each other. The first plate 6211 is provided with a U-shaped first slot 62111. The end of the first push rod 61 has a tapered head, and the first push rod 61 is engaged in the first slot 62111 through the tapered head.

[0085] The first screw connection part 622 includes a third plate 6221 and a fourth plate 6222 arranged parallel to each other. The third plate 6221 is provided with a U-shaped second slot 62211. The end of the first threaded rod 632 has a tapered head, and the first threaded rod 632 is engaged in the second slot 62211 through the tapered head.

[0086] In one embodiment, such as Figure 1 , Figure 2 As shown, the cleaning mechanism further includes a second cleaning assembly connected between the first fixed seat 9 and the second fixed seat 10. The second cleaning assembly includes an adhesive roller 81, a third support seat 82, a fourth support seat 83, a third floating assembly 84 connected to the third support seat 82, and a fourth floating assembly 85 connected to the fourth support seat 83. The third support seat 82 is fixedly mounted on the first fixed seat 9, and the fourth support seat 83 is fixedly mounted on the second fixed seat 10. The outer circumferential surface of the adhesive roller 81 abuts against the outer circumferential surface of the friction roller 5. The adhesive roller 81 is formed by sleeved adhesive paper rolls around the roller shaft. The adhesive paper can remove dirt from the surface of the friction roller 5. The outermost layer of adhesive paper covered with dirt can be periodically torn off the adhesive paper roll for cutting, thus completing the cleaning of the friction roller 5.

[0087] The first end of the adhesive roller 81 is slidably connected to the third support 82. The third floating component 84 applies an elastic support force to the first end of the adhesive roller 81, allowing the first end of the adhesive roller 81 to float up and down. The second end of the adhesive roller 81 is slidably connected to the fourth support 83. The fourth floating component 85 applies an elastic support force to the second end of the adhesive roller 81, allowing the second end of the adhesive roller 81 to float up and down. When the board to be cleaned is conveyed below the friction roller 5, the reaction force of the board on the friction roller 5 and the elastic support force of the first floating component 3 and the second floating component 4 cause the friction roller 5 to float upward. The friction roller 5 abuts against the adhesive roller 81. When the friction roller 5 floats upward, it exerts an upward thrust on the adhesive roller 81. The third floating component 84 and the fourth floating component 85 provide an upward elastic support force on the adhesive roller 81, thereby overcoming the weight of the adhesive roller 81 and allowing the adhesive roller 81 to float up and down.

[0088] The installation method of the adhesive roller 81 is the same as that of the friction roller 5. The third support 82 has the same structure as the first support 1, and the fourth support 83 has the same structure as the second support 2. These will not be described in detail here.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
