Description

A processing device and method for improving the uniformity of border film thickness Technical Field

[0001] This invention relates to the field of electroplating equipment, and in particular to a processing device and method for improving the uniformity of the thickness of a border film. Background Technology

[0002] In photovoltaic power generation equipment, solar panels are usually installed on the frame of photovoltaic modules. The frame of photovoltaic modules is an aluminum alloy profile product, which is obtained by deep processing of extruded aluminum profiles. In order to improve the corrosion resistance of the frame, a black coating is electroplated on the frame, thereby improving the durability of photovoltaic power generation equipment.

[0003] During electroplating, the bundled frame profiles are usually lowered into the electroplating bath and then lifted out after electroplating is complete. However, when electroplating in this way, the frame profiles are stacked and pressed against each other, which causes the thickness of the black film at the stacked parts to differ from that at other parts, resulting in uneven black film thickness and affecting the quality of the frame. Summary of the Invention

[0004] In order to make the thickness of the electroplated film on the frame more uniform, this application provides a processing equipment and processing method for improving the uniformity of the film thickness on the frame.

[0005] In the first aspect, the processing equipment for improving the uniformity of border film thickness provided in this application adopts the following technical solution:

[0006] A processing device for improving the uniformity of frame film thickness includes an electroplating tank for electroplating frame profiles, wherein two first pull ropes are provided in the electroplating tank, the frame profiles are scattered on the first pull ropes, and a plurality of first protrusions are provided on the first pull ropes.

[0007] By adopting the above technical solution, after the frame profile is hoisted into the electroplating tank, the hoisting rope is untied, and the frame profile is shaken and scattered between the first protrusions on the first pull rope, so that the frame profiles can be separated and the area of ​​mutual stacking and pressing is reduced, thereby making the electroplating film thickness on the frame profile more uniform after electroplating.

[0008] Preferably, the electroplating tank is further provided with two second pull ropes, each with a plurality of second protrusions. The two second pull ropes are arranged parallel above the first pull rope. Both ends of the second pull ropes are provided with driving blocks. The electroplating tank is provided with a driving device for driving the driving blocks on both sides to move closer or further apart.

[0009] By adopting the above technical solution, the initial positions of the two second pull ropes are located at both ends of the electroplating tank, reducing the impact on the placement of the frame profile on the first pull rope. When the frame profile is placed on the first pull rope, the driving device can drive the driving blocks on both sides to move closer to each other, thereby causing the driving blocks on both sides to drive the two second pull ropes to move closer to each other, so that the frame profile can also be placed on the second pull rope, increasing the electroplating efficiency of the electroplating tank.

[0010] Preferably, the driving device includes two double-ended screws rotatably disposed in the electroplating tank. The two ends of the double-ended screws have opposite thread directions. The two ends of the double-ended screws pass through two driving blocks on the same side, and the driving blocks are threadedly connected to the double-ended screws. The driving blocks abut against the inner wall of the electroplating tank. The driving device also includes a power mechanism for driving the two double-ended screws to rotate synchronously.

[0011] By adopting the above technical solution, since the two drive blocks on the same side are respectively threaded to the two ends of the double-ended screw, when the power mechanism drives the two double-ended screws to rotate synchronously, the drive blocks at both ends of the second pull rope can drive the two second pull ropes to move closer to each other, which facilitates the placement of the second layer of frame profile.

[0012] Preferably, since the two drive blocks on the same side are threaded to the two ends of the double-ended screw, when the power mechanism drives the two double-ended screws to rotate synchronously, the drive blocks at both ends of the second pull rope can drive the two second pull ropes to move closer to each other, which facilitates the placement of the second layer of frame profile.

[0013] By adopting the above technical solution, when the forward motor starts, the forward drive gear can drive one of the double-headed screws to rotate through the forward driven gear, and under the transmission of the chain and sprocket, the two double-headed screws rotate synchronously in the forward direction, so that the two second lifting ropes move closer to each other.

[0014] Preferably, the inner wall of the electroplating tank has two sliding grooves located on the same side wall. The inner wall of each sliding groove has a connecting groove that communicates with the other sliding groove. The bottom wall of the connecting groove has a strip-shaped groove, the length of which is parallel to the direction of the sliding groove. The strip-shaped groove is located in the middle of the connecting groove. A first control component is provided inside the electroplating tank. The first control component includes two sliding sealing blocks slidably disposed within the sliding grooves. One end of a first pull rope is fixedly connected to the inner wall of the electroplating tank, and the other ends of the two first pull ropes are fixedly fixed to the two sliding sealing blocks. A trigger rod is slidably disposed within the connecting groove, the width of which is smaller than the width of the connecting groove. Connecting ropes are fixedly connected to each sliding sealing block. The connecting rope is fixed to both ends of the trigger rod on the side away from the sliding sealing block. A trigger block is slidably disposed in the strip groove. The trigger rod is installed on the trigger block. A first spring is disposed in the strip groove to prevent the trigger block from sliding inward toward the electroplating tank. A first fixed contact is embedded in the inner wall of the strip groove. A first movable contact is embedded in the side of the trigger block to abut against the first fixed contact. A first power supply and a time relay are fixedly installed on the electroplating tank. The first movable contact is electrically connected to one terminal of the time relay. The other terminal of the time relay is electrically connected to one electrode of the first power supply. The other electrode of the first power supply is electrically connected to one terminal of the forward motor. The other terminal of the forward motor is electrically connected to the first fixed contact.

[0015] By adopting the above technical solution, when a frame profile of a predetermined weight is placed on the first pull rope, the first pull rope can pull the trigger rod towards the inner cavity of the electroplating tank through the sliding sealing block and the connecting rope. The trigger rod drives the trigger block to slide towards the inner cavity of the electroplating tank, so that the first moving contact piece and the first fixed contact piece come into contact. After the first pull rope carries a certain amount of frame profile, the forward motor automatically starts and automatically drives the second pull ropes on both sides to move closer to each other. Under the action of the time relay, the forward motor starts and stops automatically after a predetermined time, so that the second pull rope stops automatically after reaching the predetermined position, which makes it convenient for the frame profile to be placed on the second pull rope.

[0016] Preferably, the trigger rod is rotatably mounted on the top surface of the trigger block via a pin.

[0017] By adopting the above technical solution, since the width of the trigger rod is smaller than the width of the connecting groove, and the trigger rod is rotatably mounted on the trigger block via a pin, during the process of placing the frame profile on the first pull rope, it is difficult to maintain the absolute balance of the frame profile. When the frame profile first applies pressure to one of the first pull ropes, the trigger rod will swing, preventing the trigger block from sliding and causing the first moving contact piece to contact the first fixed contact piece. Only when both ends of the frame profile are placed on the two first pull ropes can the trigger rod drive the trigger block to slide, causing the first moving contact piece to contact the first fixed contact piece. This reduces the occurrence of the second pull ropes starting to approach each other before the lower frame profile is properly placed.

[0018] Preferably, the electroplating tank is further provided with a reverse motor, a reverse drive gear is fixedly connected to the output shaft of the reverse motor, and a reverse driven gear is fixedly connected to the double-ended screw away from the forward motor, and the reverse drive gear meshes with the reverse driven gear.

[0019] By adopting the above technical solution, when the reverse motor starts, the reverse drive gear can drive the double-headed screw to rotate in the opposite direction through the reverse driven gear, thereby causing the two second pull ropes to move away from each other. This facilitates the removal of the lower electroplated frame profile after the upper frame profile has been electroplated and lifted out of the electroplating tank.

[0020] Preferably, one of the driving blocks has a movable groove, and the electroplating tank is further provided with a second control component. The second control component includes a movable block slidably disposed in the movable groove, a second spring for preventing the movable block from sliding out of the movable groove, a first damping rod for preventing the movable block from sliding into the movable groove, a second fixed contact piece embedded in the inner wall of the movable groove, and a second movable contact piece embedded in the movable block that can abut against the second fixed contact piece. The inner wall of the electroplating tank is also provided with a transverse sliding groove, in which a control block is slidably disposed. The end face of the control block abuts against the side of the driving block. A third spring for preventing the control block from sliding is slidably disposed in the transverse sliding groove, and a third fixed contact piece, which is elongated, is embedded in the inner wall of the transverse sliding groove. A groove is provided on the side of the control block, in which a movable contact piece is slidably disposed. A third movable contact is provided that can abut against the third fixed contact. A fourth spring is provided in the groove to push the third movable contact out of the groove. A second damping rod is also provided in the groove to prevent the third movable contact from sliding out of the groove. An attraction block is fixedly connected to the third movable contact. An electromagnet that can generate an attraction force on the attraction block is fixed on the inner wall of the groove. A second power supply and a third power supply are also fixedly installed on the electroplating tank. The second fixed contact is electrically connected to one of the terminals of the electromagnet. The other terminal of the electromagnet is electrically connected to one of the electrodes of the second power supply. The other electrode of the second power supply is electrically connected to the second movable contact. The third fixed contact is electrically connected to one of the electrodes of the third power supply. The other electrode of the third power supply is electrically connected to one of the terminals of the reverse motor. The other terminal of the reverse motor is electrically connected to the third movable contact.

[0021] By adopting the above technical solution, when the two second pull ropes are at their initial positions at both ends of the electroplating tank, there is no frame profile on the second pull ropes. The second moving contact is in contact with the second fixed contact, and the electromagnet's electrical circuit is in a conductive state. The electromagnet pulls the third moving contact completely into the groove through the attraction block, causing the third moving contact to detach from the third fixed contact, and the reverse motor is de-energized. When the two second pull ropes approach each other, the control block overcomes the elastic force of the third spring under the action of the resistance with the drive block and slides to the other end of the transverse slide groove, placing the frame profile on the second pull rope. At this time, the second pull rope can pull the movable block out of the movable groove, causing the second moving contact to detach from the second fixed contact. At this time, the electromagnet's electrical circuit is broken, and the electromagnet loses its attraction to the attraction block. Under the action of the fourth spring and the second damping rod, the third moving contact slowly approaches the third fixed contact, giving the frame profile time for electroplating and time to be lifted away after electroplating. When the third moving contact piece contacts the third fixed contact piece, the reverse motor automatically starts, and the drive block moves the second pull rope towards both ends of the electroplating tank, returning to the initial position to facilitate the lifting of the lower frame profile. After the frame profile is lifted off the second pull rope, the second moving contact piece slowly slides into the movable groove under the action of the second spring and the first damping rod. When the drive block returns to the initial position, the second moving contact piece contacts the second fixed contact piece. At this time, the third moving contact piece disengages from the third moving contact piece, and the reverse motor automatically stops.

[0022] Secondly, this application provides a processing method for improving the uniformity of border film thickness, which adopts the following technical solution:

[0023] A processing method for improving the uniformity of frame film thickness includes the following steps: S1: hoisting the frame profile that has not been electroplated black onto the first pull rope, and detaching the pull rope from the frame profile, thus separating the frame profiles on the first pull rope; S2: hoisting the frame profile that has not been electroplated black onto the second pull rope, and detaching the pull rope from the frame profile, thus separating the frame profiles on the second pull rope; S3: hoisting the frame profile that has been electroplated black off the second pull rope; S4: hoisting the frame profile that has been electroplated black off the first pull rope.

[0024] By adopting the above technical solution, the frame profiles can be separated, reducing the area of ​​mutual stacking and pressing, thereby making the electroplating film thickness on the frame profiles more uniform after electroplating.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. After hoisting the frame profile into the electroplating tank, untie the hoisting rope, shake the frame profile and scatter it between the first protrusions on the first pull rope, so that the frame profiles can be separated and the area of ​​mutual stacking and pressing is reduced, so that the electroplating film thickness on the frame profile is more uniform after electroplating.

[0027] 2. Since the width of the trigger rod is smaller than the width of the connecting groove, and the trigger rod is rotatably mounted on the trigger block via a pin, during the process of placing the frame profile on the first pull rope, it is difficult to maintain the absolute balance of the frame profile. When the frame profile first applies pressure to one of the first pull ropes, the trigger rod will swing, preventing the trigger block from sliding and causing the first moving contact piece to contact the first fixed contact piece. Only when both ends of the frame profile are placed on the two first pull ropes can the trigger rod drive the trigger block to slide, causing the first moving contact piece to contact the first fixed contact piece. This reduces the occurrence of the second pull ropes starting to approach each other before the lower frame profile is properly placed.

[0028] 3. When the two second pull ropes are in their initial positions at both ends of the electroplating tank, there is no frame profile on the second pull ropes. The second moving contact is in contact with the second fixed contact, and the electromagnet's electrical circuit is in a conductive state. The electromagnet pulls the third moving contact completely into the groove through the attraction block, causing the third moving contact to separate from the third fixed contact, and the reverse motor is de-energized. When the two second pull ropes approach each other, the control block overcomes the elastic force of the third spring under the action of the resistance with the drive block and slides to the other end of the transverse slide groove, placing the frame profile on the second pull rope. At this time, the second pull rope can pull the movable block out of the movable groove, causing the second moving contact to separate from the second fixed contact. At this time, the electromagnet's electrical circuit is broken, and the electromagnet loses its attraction to the attraction block. Under the action of the fourth spring and the second damping rod, the third moving contact slowly approaches the third fixed contact, giving the frame profile time for electroplating and time to be lifted away after electroplating. When the third moving contact piece contacts the third fixed contact piece, the reverse motor automatically starts, and the drive block moves the second pull rope towards both ends of the electroplating tank, returning to the initial position to facilitate the lifting of the lower frame profile. After the frame profile is lifted off the second pull rope, the second moving contact piece slowly slides into the movable groove under the action of the second spring and the first damping rod. When the drive block returns to the initial position, the second moving contact piece contacts the second fixed contact piece. At this time, the third moving contact piece disengages from the third moving contact piece, and the reverse motor automatically stops. Attached Figure Description

[0058] The implementation principle of the processing equipment for improving the uniformity of the thickness of the frame film in this application embodiment is as follows: after the frame profile 9 is hoisted into the electroplating tank 1, the hoisting rope is untied, and the frame profile 9 is shaken and scattered between the first protrusions 21 on the first pull rope 2, so that the frame profiles 9 can be separated and the area of ​​mutual stacking and pressing is reduced, thereby making the thickness of the electroplated film on the frame profile 9 more uniform after electroplating.

[0059] When a predetermined weight of frame profile 9 is placed on the first pull rope 2, the first pull rope 2 can pull the trigger rod 72 towards the inner cavity of the electroplating tank 1 through the sliding sealing block 71 and the connecting rope 78. The trigger rod 72 drives the trigger block 73 to slide towards the inner cavity of the electroplating tank 1, so that the first moving contact piece 75 and the first fixed contact piece 74 come into contact. After the first pull rope 2 bears a certain amount of frame profile 9, the forward motor 64 starts automatically and automatically drives the second pull ropes 3 on both sides to move closer to each other. Under the action of the time relay 77, the forward motor 64 starts for a predetermined time and then stops automatically, so that the second pull rope 3 stops automatically after reaching the predetermined position, which makes it easy for the frame profile 9 to be placed on the second pull rope 3.

[0060] When the two second pull ropes 3 are in their initial positions at both ends of the electroplating tank 1, the frameless profile 9 on the second pull rope 3, the second moving contact 811 and the second fixed contact 42 are in contact. At this time, the electrical circuit of the electromagnet 88 is in a conducting state. The electromagnet 88 pulls the third moving contact 842 completely into the groove 841 through the attraction block 87, so that the third moving contact 842 is separated from the third fixed contact 141, and the reverse motor 67 is in a de-energized state. When the two second pull ropes 3 approach each other, the control block 84, under the action of contact with the drive block 4, overcomes the elastic force of the third spring 85 and slides to the other end of the transverse slide groove 14, placing the frame profile 9 on the second pull rope 3. At this time, the second pull rope 3 can pull the movable block 81 outwards from the movable groove 41, causing the second moving contact 811 to disengage from the second fixed contact 42. At this time, the electric circuit of the electromagnet 88 is disconnected, and the electromagnet 88 loses its attraction to the attraction block 87. Under the action of the fourth spring 843 and the second damping rod 86, the third moving contact 842 slowly approaches the third fixed contact 141, giving the frame profile 9 time for electroplating and time to be lifted away after electroplating. When the third moving contact 842 contacts the third fixed contact 141, the reverse motor 67 automatically starts, and the drive block 4 drives the second pull rope 3 to move towards both ends of the electroplating tank 1, returning to the initial position, which facilitates the lifting away of the lower frame profile 9. When the frame profile 9 is lifted off the second rope, the second movable contact 811 slowly slides into the movable groove 41 under the action of the second spring 82 and the first damping rod 83. When the drive block 4 returns to the initial position, the second movable contact 811 contacts the second fixed contact 42. At this time, the third movable contact 842 disengages from the third movable contact 842, and the reverse motor 67 stops automatically.

[0061] This application also discloses a processing method for improving the uniformity of frame film thickness, comprising the following steps: S1: hoisting the frame profile 9 that has not been electroplated black onto the first pull rope 2, and detaching the pull rope on the first pull rope 2 from the frame profile 9, thus separating the frame profile 9 on the first pull rope 2; S2: hoisting the frame profile 9 that has not been electroplated black onto the second pull rope 3, and detaching the pull rope on the second pull rope 3 from the frame profile 9, thus separating the frame profile 9 on the second pull rope 3; S3: hoisting the frame profile 9 that has been electroplated black off the second pull rope 3; S4: hoisting the frame profile 9 that has been electroplated black off the first pull rope 2.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
