Description

Technical Field

[0001] The present invention relates to the technical field of electroplating equipment, and particularly relates to a guide rod type electroplating production line. Background Art

[0002] The production of circuit boards requires an electroplating process step. During the electroplating process of the circuit board, the circuit board is transported into the electroplating tank through a conveying mechanism for electroplating.

[0003] For example, an electroplating production line disclosed in Chinese Patent Document CN112746305A, the circuit board is fixed on the conveyor belt of the conveying mechanism through a fixture, and then sequentially passes through a loading area, a cleaning area, an electroplating area, a cleaning area, a drying area, and an unloading area.

[0004] However, in the above solution, the plate is only clamped to the conveyor belt at the upper end.

[0061] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0062] This embodiment provides a guide rod type electroplating production line. The electroplating process is carried out on the plate 10 through an electroplating tank. The electroplating process generally includes processes such as loading, cleaning, electroplating, cleaning, and drying.

[0063] Such as Figure 1As shown in the figure, the guide rod type electroplating production line provided in this embodiment sequentially includes: a loading area 1, a cleaning area 2, a water washing area 3, a pre-impregnation area 4, a plurality of electroplating areas 5, a water washing area 3, a drying area 6, and a unloading area 7. In the cleaning area 2, the surface of the plate 10 is cleaned by blowing gas towards the plate 10; in the water washing area 3, the plate 10 is deeply cleaned by blowing washing liquid towards the plate 10; in the pre-impregnation area 4, the plate 10 is pretreated by a pre-impregnation liquid; in the electroplating area 5, the plate 10 is subjected to multiple electroplating treatments by an electroplating liquid. After electroplating the plate 10, the electroplated plate is cleaned in the water washing area 3, and then the plate 10 is dried in the drying area 6 for stacking. Among them, the electroplating areas 5 are sequentially connected by electroplating tanks, the inside of the electroplating tanks is adapted to accommodate the electroplating liquid, and a liquid blocking device 9 is respectively provided at the inlet end and the outlet end of each electroplating tank.

[0064] As Figure 1 shown, a conveyor belt 8 is provided above the above-mentioned loading area 1, cleaning area 2, water washing area 3, pre-impregnation area 4, plurality of electroplating areas 5, water washing area 3, drying area 6, and unloading area 7. The plate 10 is conveyed through the conveyor belt 8 and passes through the above-mentioned areas in sequence, so as to perform the electroplating process on the plate 10. As Figure 2 shown, a clamping assembly is provided on the conveyor belt 8, and the plate 10 is clamped and suspended through the clamping assembly. Specifically, the clamping assembly includes: an upper clamp 11 and a lower clamp 12. The upper clamp 11 is directly fixedly connected to the conveyor belt 8, and the lower clamp 12 is fixedly connected to a sliding rod 13. The sliding rod 13 is connected to the conveyor belt 8 in a vertically adjustable manner through an adjusting clamp 14. The upper end of the plate 10 is clamped by the upper clamp 11, and the lower end of the plate 10 is processed by the lower clamp 12, so as to avoid the shaking of the plate 10 during the conveyance by the conveyor belt 8 and avoid the problem of the plate 10 getting stuck. In addition, since the sliding rod 13 can be adjusted up and down, the lower clamp 12 can be driven to adjust the height to adapt to the clamping of plates 10 of different specifications. As Figure 11 , Figure 12As shown, the lower fixture 12 in the clamping assembly is made thinner in order to better pass through the liquid blocking device 9. Specifically, the lower fixture 12 includes a mounting plate 15 and a clamping member 17 rotatably connected to the mounting plate 15. The clamping member 17 has a clamping portion 19 that cooperates with the mounting plate 15 to clamp the sheet 10. The clamping member 17 also has an unclamping portion 18 for unclamping. Driving the unclamping portion 18 can make the chuck 20 of the clamping portion 19 move away from or close to the mounting plate 15. The mounting plate 15 has an avoidance opening 16, and the unclamping portion 18 is recessed in the avoidance opening 16, thereby reducing the protrusion of the unclamping portion 18 in the thickness direction of the fixture and reducing the overall thickness of the lower fixture 12, making it easier to pass through the gap between the two water blocking rollers.

[0065] As Figure 3 shown, the liquid blocking device 9 includes a first liquid blocking roller 21 and a second liquid blocking roller 22. The two liquid blocking rollers are respectively rotatably provided on a base 23. The two liquid blocking rollers are arranged oppositely and their axes are parallel to each other. The mutually approaching sides of the two liquid blocking rollers are in sealed contact and form a passing gap for the sheet 10 to pass through when being squeezed. Elastic sleeves are respectively sleeved on the two liquid blocking rollers, and the elastic sleeves can be elastic materials such as rubber foam sponge.

[0066] As Figure 4 shown, liquid blocking bending members 24 are respectively provided on both sides of the liquid blocking roller. One end of the liquid blocking bending member 24 is fixedly connected to a fixing plate 25, and the other end elastically abuts against the outer circumference of the liquid blocking roller. A regulating member 26 is movably connected to the fixing plate 25. The regulating member 26 can adjust the abutting force between the liquid blocking bending member 24 and the liquid blocking roller by abutting against the liquid blocking bending member 24. Specifically, the regulating member 26 can be a fastener such as a butterfly bolt. As Figure 4 、 Figure 5 shown, a notch 27 for passing a guide rod is formed on the first liquid blocking roller 21. During the process of conveying the sheet 10 by the conveyor belt 8, when the guide rod passes through the passing gap, it can be recessed into the notch 27, so that the guide rod can pass more conveniently, and avoid the reaction force of the guide rod on the liquid blocking roller causing the liquid blocking roller to be deformed or displaced under force, ensuring the smooth operation of the system.

[0067] As Figure 6 、 Figure 7As shown, the liquid-blocking roller in the liquid-blocking device 9 is driven by the driving device to rotate, and the conveyor belt 8, while driving the plate 10 to move, also serves as the first transmission mechanism to provide rotational power for the liquid-blocking roller, and to make the liquid-blocking roller of the liquid-blocking device 9 move synchronously with the conveyor belt 8. Specifically, the second transmission mechanism is driven by the first transmission mechanism to convert the linear movement of the conveyor belt 8 into the rotation of the liquid-blocking roller, and to make the rotational linear speed of the liquid-blocking roller equal to the moving speed of the conveyor belt 8, so that when the plate 10 passes between the two liquid-blocking rollers, the friction between the plate 10 and the liquid-blocking roller can be reduced. The second transmission mechanism includes: a first transmission shaft 31, a coupling 32 and a transmission member 30; wherein the transmission member 30 is a wheel disc that rotates synchronously with the conveyor belt 8, and a plurality of protrusions 33 are arranged on the outer peripheral wall of the wheel disc at intervals along the circumferential direction, and the protrusions 33 are used to plug and match with the conveyor belt 8. The conveyor belt 8 has a recessed portion for matching with the protrusion 33. The plurality of protrusions 33 on the wheel disc are constituted as follows: a plurality of slots are distributed at intervals along the circumferential direction on the outer peripheral wall of the wheel disc, a toggle portion is inserted in each of the slots, and at least a part of the structure of the toggle portion extends out of the slot, thereby forming the protrusion 33. In addition, it also includes: an inductive sensor 34 for detecting the rotation speed of the wheel disc, the inductive sensor 34 cooperates with the inductive point on the outer peripheral wall of the wheel disc, thereby detecting the rotation speed of the wheel disc, and the inductive point on the outer peripheral wall of the wheel disc is arranged on the protrusion 33. The wheel disc is arranged on the first transmission shaft 31, and the coupling 32 connects the first transmission shaft 31 and the corresponding rotating shaft of the liquid retaining roller respectively; specifically, the coupling 32 connects the first transmission shaft 31 and the rotating shaft of the liquid retaining roller through the meshing between gears. The coupling 32 includes: a first synchronous gear 35, a second synchronous gear 36 and an idler gear 37; wherein the first synchronous gear 35 is fixed on the first transmission shaft 31, the second synchronous gear 36 is fixed on the rotating shaft of the liquid-blocking roller, and the idler gear 37 is meshed between the first synchronous gear 35 and the second synchronous gear 36, so as to realize meshing transmission between the second synchronous gear 36 and the first synchronous gear 35. When working, driven by the first transmission mechanism, the wheel plate drives the first transmission shaft 31 to rotate, and simultaneously drives the corresponding liquid-blocking roller to rotate through the coupling 32.

[0068] like Figure 1 As shown, a loading and unclamping device 28 is provided at the inlet of the electroplating tank, and a unloading and unclamping device 29 is provided at the outlet of the electroplating tank. The loading and unclamping device 28 and the unloading and unclamping device 29 have similar structures, so they are collectively referred to as loading and unloading and unclamping devices. Figure 2 , Figure 7 , Figure 8As shown, the loading and unloading clamping device includes: a first frame 38 and a second frame 39 which are oppositely arranged. Both the first frame 38 and the second frame 39 are movably connected to the machine frame 41 through slide rails 40. The first frame 38 and the second frame 39 are on the machine frame 41 and can be driven by a sliding driving member 42 to move synchronously with the conveyor belt. Between the first frame 38 and the second frame 39, a clamping assembly connected by a conveyor belt 8 is adapted to be accommodated. When the sheet 10 is conveyed into the machine frame 41, the sheet 10 needs to be connected to the moving conveyor belt 8 through the clamping assembly. At this time, through the loading and unloading clamping device that moves synchronously with the conveyor belt 8, the upper clamp 11 and the lower clamp 12 connected to the conveyor belt 8 can be opened, and the height of the lower clamp 12 can be adjusted to adapt to the specification of the sheet 10. Thus, the sheet 10 can be moved to the clamping area by a manipulator to complete the loading of the sheet 10. Above the first frame 38, there is a first upper clamping and opening mechanism 43, and above the second frame 39, there is a second upper clamping and opening mechanism 44 opposite to the first upper clamping and opening mechanism 43; below the first frame 38, a first lower clamping and opening mechanism 45 is slidably connected, and below the second frame 39, a second lower clamping and opening mechanism 46 is slidably connected. The first lower clamping and opening mechanism 45 and the second lower clamping and opening mechanism 46 are adapted to be driven to move in the vertical direction; when performing the loading work, the upper clamp 11 is opened and clamped through the cooperation of the first upper clamping and opening mechanism 43 and the second upper clamping and opening mechanism 44, and the lower clamp 12 is opened and clamped through the cooperation of the first lower clamping and opening mechanism 45 and the second lower clamping and opening mechanism 46. Among them, the first lower clamping and opening mechanism 45 and the second lower clamping and opening mechanism 46 can be driven to move in the vertical direction. Specifically, when adjusting the height of the lower clamp 12, the first lower clamping and opening mechanism 45 and the second lower clamping and opening mechanism 46 are adjusted simultaneously by a guide rod lifting device, so that the first lower clamping and opening mechanism 45 and the second lower clamping and opening mechanism 46 adapt to the height of the lower clamp 12 to accurately complete the opening and clamping operation of the lower clamp 12.

[0069] As Figure 7 , Figure 8As shown in the figure, a guide rod lifting device is further provided in the lower area between the first frame 38 and the second frame 39. The guide rod lifting device includes: a mounting frame 47, which is fixedly hoisted on the first frame 38 and the second frame 39 to ensure that the guide rod lifting device and the first frame 38 and the second frame 39 can move synchronously along the slide rail 40. There is a supporting member 49 on the guide rod lifting device that can move up and down. When the supporting member 49 moves upward, it is adapted to abut against the lower end of the guide rod. Thus, after the adjusting clamp 14 at the upper end of the guide rod is opened, the supporting member 49 can drive the guide rod to move up and down. A lifting drive device 48 for driving the supporting member 49 to move up and down is connected to the mounting frame 47, and the lifting drive device 48 can be any one of an electric push rod, a cylinder or an oil cylinder for driving.

[0070] As Figure 8 shown, on the supporting member 49, there is a first pushing member 50 extending towards the direction of the first lower clamping mechanism 45, and a second pushing member 51 extending towards the direction of the second lower clamping mechanism 46. The top heights of the first pushing member 50 and the second pushing member 51 are equal; when the supporting member 49 moves upward to drive the guide rod, the first pushing member 50 abuts against the first lower clamping mechanism 45, and the second pushing member 51 abuts against the second lower clamping structure, so as to synchronously adjust the heights of the first lower clamping mechanism 45 and the second lower clamping mechanism 46 to adapt to the position of the lower clamp 12 and achieve accurate clamping opening. Since the top heights of the first pushing member 50 and the second pushing member 51 are equal, the heights of the first lower clamping mechanism 45 and the second lower clamping mechanism 46 can be ensured to be equal, thus facilitating coordinated clamping opening. In addition, as a preferred embodiment, the first pushing member 50 and the second pushing member 51 on the supporting member 49 extend upward at an angle towards the direction of mutual separation. With such a setting, the first pushing member 50 and the second pushing member 51 on the supporting member 49 can respectively more easily abut against the first lower clamping mechanism 45 and the second lower clamping mechanism 46, thus ensuring that the heights of the two lower clamping mechanisms are equal.

[0071] As Figure 9 、 Figure 10As shown, the manipulator picks up and places the sheet 10 through the suction cup structure. The manipulator is arranged in the areas of the loading clamp-opening device 28 and the unloading clamp-opening device 29. The suction cup structure of the manipulator includes: an upper suction cup 52, a lower suction cup 53 and a connecting frame 54. The upper suction cup 52 and the lower suction cup 53 are connected to the connecting frame 54 in the same plane, and the upper suction cup 52 and the lower suction cup 53 are slidably connected to the connecting frame 54, so that the distance between the upper suction cup 52 and the lower suction cup 53 can be adjusted to adapt to sheets 10 of different specifications. Specifically, a suction cup driving member 55 is further arranged on the connecting frame 54. The suction cup driving member 55 is respectively connected to the upper suction cup 52 and the lower suction cup 53. The suction cup driving member 55 is used to drive the lower suction cup 53 to slide in a direction close to or away from the upper suction cup 52. The suction cup driving member 55 can be driven by a motor and transmitted through a transmission screw rod 56, so that the upper suction cup 52 and the lower suction cup 53 can move closer to or away from each other simultaneously.

[0072] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
