Description

Technical Field

[0001] This invention relates to the field of circuit board processing equipment technology, and in particular to a circuit board processing equipment with a chemical shaking function. Background Technology

[0002] In automated PCB (Printed Circuit Board) production, chemicals can remain on the circuit boards and fixtures. This residue can flow with the circuit boards to subsequent equipment, mixing and causing contamination. When contamination reaches a certain level, the remaining chemicals need to be discarded, increasing costs. Furthermore, chemicals on the fixtures can flow to other locations, where they can crystallize. These crystals can fall into the chemical tank, clogging filters and increasing maintenance frequency. The crystals can also adhere to the surface of the circuit boards and inside their holes, further increasing the defect rate. Summary of the Invention

[0003] The main objective of this invention is to provide a circuit board processing device with a chemical shaking function, which aims to reduce the defect rate of circuit boards.

[0004] To achieve the above objectives, the present invention provides a circuit board processing device with a chemical shaking function, comprising:

[0005] A frame and a fixture, wherein the frame is provided with an immersion position and a dispersing position;

[0006] A vibration assembly includes a drive component mounted on the frame, a vibrating component mounted on the drive component, and a vibrating plate mounted on the vibrating component, wherein the vibrating component and the vibrating plate are kinetically connected; and

[0007] A rotating assembly is mounted on the frame and is connected to the clamp via a transmission mechanism. The rotating assembly drives the clamp to rotate from the soaking position to the shaking position. The driving component drives the vibrating component and the vibrating plate to move to the shaking position. The vibrating component drives the vibrating plate to vibrate, thereby shaking off the clamp located at the shaking position and the medicine located on the circuit board on the clamp.

[0008] Optionally, the vibrating plate includes a connecting plate and a support plate. The connecting plate is drivenly connected to the output shaft of the vibrating element, and the support plate is rotatably connected to the connecting plate. The support plate has an initial position and a disengaged position. When the support plate is in the shaking position, the rotating component drives the clamp to rotate so as to move the support plate from the initial position to the disengaged position. At the disengaged position, the support plate disengages from the clamp, and the support plate returns to the initial position under the action of gravity.

[0009] Optionally, the vibrating plate further includes a rotating rod, and the connecting plate and the support plate are respectively provided with a first rotating hole and a second rotating hole. The support plate is rotatably connected to the connecting plate through the cooperation of the rotating rod with the first rotating hole and the second rotating hole.

[0010] Optionally, the connecting plate is provided with a limiting member. When the tray is in the initial position, the tray abuts against the limiting member to restrict the tray from rotating downward.

[0011] Optionally, the tray is provided with a convex arc surface on the side facing the soaking position.

[0012] Optionally, the driving component includes an extension cylinder mounted on the frame and a lifting cylinder that is hygienically connected to the output shaft of the extension cylinder. The extension cylinder drives the lifting cylinder, the vibrating element, and the vibrating plate to move horizontally, and the lifting cylinder drives the vibrating element and the vibrating plate to move up and down.

[0013] Optionally, the vibrating element is a vibrating cylinder.

[0014] Optionally, the frame is provided with a soaking chamber located at the soaking position for soaking the circuit board on the fixture.

[0015] Optionally, it also includes a transport component and a storage compartment, both mounted on the frame. The frame is also provided with a transport position, the transport component is located at the transport position, the rotating component drives the clamp to rotate from the dispersing position to the transport position, and the transport component drives the circuit board located on the clamp at the transport position to move to the storage compartment.

[0016] Optionally, the rotating assembly includes a rotating motor, a first rotating shaft, multiple second rotating shafts, a rotating gear, and a rotating chain. The rotating motor is mounted on the frame, and the output shaft of the rotating motor is connected to one end of the first rotating shaft. The first rotating shaft is fixed to the rotating gear, and the rotating motor drives the rotating gear to rotate through the first rotating shaft. The rotating chain is sleeved on the rotating gear, and the multiple second rotating shafts are fixed at intervals on the rotating chain. The clamping device is mounted on the second rotating shaft, and one clamping device corresponds to one second rotating shaft.

[0017] This invention employs a method of mounting a drive unit and a rotating assembly on a frame, with a soaking position and a dispersing position on the frame. A vibrating element is mounted on the drive unit, and a vibrating plate is mounted on the vibrating element. When the rotating assembly drives the fixture from the soaking position to the dispersing position, the drive unit drives the vibrating element and vibrating plate to move to the dispersing position to contact the fixture. At this point, the vibrating element drives the vibrating plate to vibrate, causing the fixture to vibrate and dissipate the chemicals from the fixture and the circuit board on it. This effectively cleans the fixture and the circuit board, reducing the possibility of chemicals crystallizing and adhering to the holes in the circuit board, thus lowering the defect rate of the circuit board. It also reduces the damage to subsequent processes caused by chemicals adhering to the circuit board and fixture, thereby lowering production costs. Attached Figure Description

[0032] Reference Figure 1 and Figure 2 This invention proposes a circuit board processing device with a shaking function for dispersing chemicals, comprising:

[0033] The frame 10 and the clamp 20 are provided, wherein the frame 10 is provided with a soaking position 11 and a shaking position 12;

[0034] The vibration assembly includes a drive component mounted on the frame 10, a vibrating component mounted on the drive component, and a vibrating plate mounted on the vibrating component, wherein the vibrating component and the vibrating plate are throttle connected; and

[0035] A rotating assembly 40 is mounted on the frame 10 and is connected to the clamp 20 in a transmission manner. The rotating assembly 40 drives the clamp 20 to rotate from the soaking position 11 to the shaking position 12. The driving member drives the vibrating member and the vibrating plate to move to the shaking position 12. The vibrating member drives the vibrating plate to vibrate, so as to shake off the clamp 20 and the medicine on the circuit board located on the clamp 20 located at the shaking position 12.

[0036] The technical solution of this invention employs a drive component and a rotating assembly 40 mounted on a frame 10, with an immersion position 11 and a dispersing position 12 set on the frame 10. A vibrating component is mounted on the drive component, and a vibrating plate is mounted on the vibrating component. When the rotating assembly 40 drives the clamp 20 from the immersion position 11 to the dispersing position 12, the drive component drives the vibrating component and the vibrating plate to move to the dispersing position 12 to abut against the clamp 20. At this time, the vibrating component drives the vibrating plate to vibrate, thereby causing the clamp 20 to vibrate and dissipate the chemicals from the clamp 20 and the circuit board on it. This achieves the effect of cleaning the clamp 20 and the circuit board on it, reducing the possibility of chemicals crystallizing and adhering to the holes in the circuit board, thus reducing the defect rate of the circuit board. It also reduces the damage to subsequent processes caused by chemicals adhering to the circuit board and the clamp 20, thereby reducing production costs.

[0037] It should be noted that the subsequent process mentioned in this article may involve a second chemical soaking of the circuit board. If the chemical solution is not shaken off at this point, it will contaminate the solution at the second soaking site. Once the contamination reaches a certain level, the subsequent chemical solution will need to be discarded, thus increasing the cost of the chemical solution. Of course, it is also possible that the chemical solution adhering to the circuit board may fall onto the equipment during transportation, causing corrosion to the equipment. This is not only difficult to clean, but may also increase environmental pollution in the production process, thereby increasing the harm to human health.

[0038] In this embodiment, the circuit board processing equipment with the function of shaking medicine also includes a transport component and a storage compartment 60 both installed on the frame 10. The frame 10 is also provided with a transport position 13. The rotating component 40 drives the clamp 20 to rotate from the shaking position 12 to the transport position 13. The transport component drives the circuit board located on the clamp 20 at the transport position 13 to move to the storage compartment 60.

[0039] The rotating component 40 moves multiple clamps 20 from the soaking position 11 to the shaking position 12 for vibration treatment, and then continues to rotate to move the upstream clamps 20 to the shaking position 12 and the downstream clamps 20 to the transport position 13. This process is repeated to greatly improve the production efficiency of the circuit board.

[0040] Reference Figure 1 , Figure 4 and Figure 5 Specifically, the transport assembly includes a transport cylinder, a transport claw 51, a first transport motor, a first transport rod 52, and a transport frame. The transport frame is mounted on the frame 10. The transport cylinder and the first transport motor are both mounted on the transport frame. The transport claw 51 is driven to the output shaft of the transport cylinder. The transport claw 51 moves the circuit board located on the clamp 20 at the transport position 13 onto the first transport rod 52. One end of the first transport rod 52 is driven to the output shaft of the first transport motor. The first transport motor drives the first transport rod 52 to rotate, thereby moving the circuit board to the storage compartment 60.

[0041] Of course, in another embodiment, the first transport motor may not be provided. The transport cylinder, during the process of gripping the circuit board by the transport claw 51, drives the first transport rod 52 to move. The reason for providing the first transport rod 52 is to reduce the friction experienced by the circuit board during movement, thereby reducing wear and increasing the yield rate. It should be further noted that transport rollers 59 can also be installed on the first transport rod 52 and the second transport rod 53. By providing transport rollers 59, the contact between the circuit board and the transport components is further reduced, further reducing wear. Simultaneously, the transport rollers 59 can be made of materials such as silicone or rubber. These materials are relatively soft, thus minimizing wear on the circuit board during transport, further reducing wear during transportation.

[0042] Furthermore, the transport assembly also includes a lifting assembly, a second transport motor 55, a second transport rod 53, and a lifting plate 54. The second transport motor 55 is mounted on the lifting plate 54, and the output shaft of the second transport motor 55 is connected to the second transport rod 53. The second transport rod 53 is rotatably connected to the lifting plate 54. The transport cylinder drives the transport claw 51 to move the circuit board onto the second transport rod 53. Then, the lifting assembly moves the lifting plate 54 to a predetermined height. The second transport motor 55 then drives the second transport rod 53 to rotate, thereby driving the circuit board to move into the storage compartment 60. It should be noted that the predetermined height is the height of the circuit board stack in the storage compartment, and therefore changes in real time. Therefore, the storage compartment 60 is equipped with a sensor to detect the height of the circuit board stack in the storage compartment 60, and then controls the lifting height of the lifting assembly. The lifting assembly can be a cylinder, or it can be achieved by the cooperation of a lifting motor, a lifting gear, and a lifting chain to lift the lifting plate 54. Specifically, the lifting motor drives the lifting gear to rotate, thereby driving the lifting chain to rotate, and thus the lifting chain drives the lifting plate 54 to lift.

[0043] Multiple transport cylinders and multiple second transport rods 53 can be provided. A second transport motor 55 drives a second transport rod 53 to rotate, and then the circuit board moves through multiple second first transport rods 52. Alternatively, a second transport motor 55 can drive multiple second transport rods 53 to rotate. The transport assembly also includes a transmission rod 58, one end of which is connected to the output shaft of the second transport motor 55 to make the transmission rod 58 rotate. Multiple first bevel gears 56 are installed on the transmission rod 58, and a second bevel gear 57 is installed at one end of the second transport rod 53. The first bevel gears 56 and the second bevel gears 57 mesh with each other. Multiple first bevel gears 56 are spaced apart on the transmission rod 58, and one second transport rod 53 is set with one second bevel gear 57, so that the second transport motor 55 drives multiple second transport rods 53 to rotate through one transmission rod 58. Of course, in other embodiments, the length of the second transport rod 53 is relatively long, and a second transport motor 55 and a transmission rod 58 can be installed at both ends of the second transport rod 53 to improve the transmission efficiency of the second transport rod 53.

[0044] In this embodiment, the rotating assembly 40 includes a rotating motor, a first rotating shaft, multiple second rotating shafts, a rotating gear, and a rotating chain. The rotating motor is mounted on the frame 10, and the output shaft of the rotating motor is connected to one end of the first rotating shaft. The first rotating shaft is fixed to the rotating gear, and the rotating motor drives the rotating gear to rotate through the first rotating shaft. The rotating chain is sleeved on the rotating gear, and multiple second rotating shafts are fixed to the rotating chain at intervals. The clamping device 20 is mounted on the second rotating shaft, and one clamping device 20 corresponds to one second rotating shaft.

[0045] Of course, to further improve the transmission efficiency of the rotating assembly 40, a rotating motor can be installed at both ends of the first rotating shaft, thereby further increasing the load on the first rotating shaft. The second rotating shaft can be detachably mounted on the rotating gear, allowing the operator to freely adjust the distance between adjacent second rotating shafts. The detachable connection can be secured with threaded screws or a snap-fit ​​connection.

[0046] Reference Figure 3 Preferably, the vibrating plate includes a connecting plate 34 and a support plate 35. The connecting plate 34 is drivenly connected to the output shaft of the vibrating element, and the support plate 35 is rotatably connected to the connecting plate 34. The support plate 35 has an initial position and a disengaged position. When the support plate 35 is located at the drug shaking position 12, the rotating component 40 drives the clamp 20 to rotate so as to move the support plate 35 from the initial position to the disengaged position. At the disengaged position, the support plate 35 disengages from the clamp 20, and the support plate 35 returns to the initial position under the action of gravity.

[0047] Understandably, when the drive component malfunctions and the vibrating plate stops at the shaking position 12 and cannot move, if the rotating component 40 continues to drive the clamp 20 from the soaking position 11 to the shaking position 12, interference will occur between the clamp 20 and the vibrating plate, causing damage to at least one of the clamp 20 and the vibrating plate. Therefore, in this embodiment, by rotatably connecting the tray 35 to the connecting plate 34, even if the drive component malfunctions and the vibrating plate cannot move, the rotating component 40 will drive the clamp 20 to rotate to the shaking position 12, which will cause the tray 35 to rotate. After the clamp 20 rotates past the shaking position 12, the tray 35 will return to its initial position under the action of gravity, and then repeat, thereby reducing the damage to the clamp 20, ensuring the normal operation of the equipment, providing maintenance personnel with a certain amount of time to detect problems, and improving the stability of the equipment.

[0048] In this embodiment, the vibrating plate further includes a rotating rod 36. The connecting plate 34 and the support plate 35 are respectively provided with a first rotating hole and a second rotating hole. The support plate 35 is rotatably connected to the connecting plate 34 through the cooperation of the rotating rod 36 with the first rotating hole and the second rotating hole. The rotating rod 36 has a simple structure, is easy to install, is stable and reliable, and reduces the production and manufacturing cost.

[0049] Optionally, the connecting plate 34 is provided with a limiting member 37. When the support plate 35 is in the initial position, the support plate 35 abuts against the limiting member 37 to restrict the downward rotation of the support plate. The limiting member 37 enables the support plate 35 to always hold the clamp 20 when it drives the clamp 20 to vibrate. The limiting member 37 can be a limiting plate or a limiting rod.

[0050] In this embodiment, the tray 35 is provided with a convex arc surface on the side facing the soaking position 11. By making the tray 35 an arc surface structure, it is easier for the clamp 20 to slide on the tray 35.

[0051] Specifically, the driving component includes an extension cylinder 31 mounted on the frame 10 and a lifting cylinder 32 drivenly connected to the output shaft of the extension cylinder 31. The extension cylinder 31 drives the lifting cylinder 32, the vibrating component, and the vibrating plate to move horizontally, and the lifting cylinder 32 drives the vibrating component and the vibrating plate to move up and down. Through the cooperation of the extension cylinder 31 and the lifting cylinder 32, the vibrating component and the vibrating plate are driven to move to the shaking position 12. The cylinder driving effect is simple in structure, stable and reliable, and low in cost, thereby reducing the operating cost of the equipment and improving the stability of the equipment. Among them, the vibrating component is a vibrating cylinder 33.

[0052] Furthermore, the frame 10 is provided with an immersion chamber located at the immersion position 11, which is used to immerse the circuit board on the fixture 20 and process the circuit board through the immersion chamber.

[0053] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
