[0031] Reference Figure 1 , Figure 2 and Figure 3As shown, a circuit board etching apparatus according to an embodiment of the present invention includes a conveying component 100, an etching component 200, and a flipping component 300. The following description uses the first direction as from back to front and the second direction as from left to right as examples.

[0032] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the conveying assembly 100 includes a first conveying line 110 and a second conveying line 120 arranged at intervals. The second conveying line 120 and the first conveying line 110 are arranged along a first direction, that is, the second conveying line 120 is located in front of the first conveying line 110. The first conveying line 110 and the second conveying line 120 can sequentially convey the circuit board so that the circuit board is conveyed from back to front.

[0033] Reference Figure 1 , Figure 2 and Figure 3 As shown, the etching component 200 is disposed above the first conveyor line 110 and the second conveyor line 120 to spray etching liquid onto the circuit boards on the first conveyor line 110 and the second conveyor line 120 to etch the end face of the circuit board.

[0034] Reference Figure 1 , Figure 2 and Figure 3 As shown, the flipping assembly 300 is disposed between the first conveyor line 110 and the second conveyor line 120. The flipping assembly 300 includes a first rotary driver 330, a rotary disk 310, and a first support 320. The first support 320 is disposed between the first conveyor line 110 and the second conveyor line 120 and provides support for the connection between the rotary disk 310 and the first rotary driver 330. The rotary disk 310 is rotatably connected to the first support 320, and the first rotary driver 330 is connected to the rotary disk 310 to drive the rotary disk 310 to rotate on the first support 320.

[0035] Reference Figure 1 , Figure 2 and Figure 3 As shown, the upper end of the first conveyor line 110 is provided with a first conveying surface 111, and the upper end of the second conveyor line 120 is provided with a second conveying surface 121. Both the first conveying surface 111 and the second conveying surface 121 are used to support the circuit board for conveying the circuit board. The height of the first conveying surface 111 is higher than that of the second conveying surface 121.

[0036] Reference Figure 1 , Figure 2 and Figure 3As shown, the rotating disk 310 has two accommodating slots 311 arranged symmetrically at the center. The accommodating slots 311 are open to the outside, and the openings of the accommodating slots 311 gradually narrow from the outside to the inside. The upper end of one accommodating slot 311 can be connected to the tail end of the first conveyor line 110, and the lower end of the other accommodating slot 311 can be connected to the head end of the second conveyor line 120.

[0037] Reference Figure 1 , Figure 2 and Figure 3 As shown, when the circuit board is conveyed from the beginning to the end of the first conveyor line 110, the receiving groove 311 is open to the outside, and the opening of the receiving groove 311 gradually narrows from the outside to the inside, so as to facilitate the alignment of the circuit board with the receiving groove 311 and allow the circuit board to slide down along the slope of the inner edge of the receiving groove 311, so that the circuit board and the receiving groove 311 are engaged. The first rotary driver 330 can drive the rotary disk 310 to rotate 180 degrees in the forward direction, so that the positions of the two receiving grooves 311 are exchanged, so that the opening of the receiving groove 311 containing the circuit board is open downward, so that the circuit board can slide down along the slope of the receiving groove 311. The inner edge slides down to the beginning of the second conveyor line 120 to realize the automatic flipping of the circuit board, so as to facilitate double-sided etching of the circuit board. The second conveyor line 120 can continue to transport the circuit board, avoiding the problem of etching solution accumulating on one side of the circuit board. Moreover, through the layout of the rotating disk 310 with the first conveyor line 110 and the second conveyor line 120, the transition of the circuit board between the rotating disk 310 and the first conveyor line 110 and the second conveyor line 120 can be more smooth, which is conducive to improving the accuracy of circuit board transportation and flipping, and helps to avoid problems such as circuit board accumulation, jamming or flipping failure.

[0038] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the upper and lower ends of the receiving groove 311 are provided with outwardly expanding chamfers. Taking one of the receiving grooves 311 as an example, the upper and lower edges of the outer end of the receiving groove 311 are respectively provided with arc-shaped chamfers. When the circuit board is conveyed to the tail end along the first conveying line 110, the circuit board can be connected with the chamfer of the outer end of the receiving groove 311, so that the circuit board slides into the receiving groove 311 along the chamfer at the end of the receiving groove 311.

[0039] Reference Figure 1 , Figure 2 and Figure 3As shown, the opening of the receiving groove 311 gradually narrows from the outside to the inside, that is, the opening of the receiving groove 311 is larger at the outer end and smaller at the inner end. Combined with the chamfer at the outer end of the receiving groove 311, it is convenient to align the circuit board with the receiving groove 311. Through the conveying action of the first conveying line 110 and the slope of the receiving groove 311, the circuit board can smoothly slide into the receiving groove 311.

[0040] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the inner wall of the receiving tank 311 is connected to multiple liquid outlets. Specifically, the rotating disk 310 is connected to liquid outlets at the left and right ends of the receiving tank 311, respectively. The liquid outlets are designed so that the etching solution sliding down from the end face of the circuit board can flow out from the liquid outlets.

[0041] Reference Figure 1 , Figure 2 and Figure 3 As shown, the circuit board etching device is designed with an outlet so that the etching solution can flow out of the receiving tank 311 quickly, thereby reducing or avoiding the problem of the etching solution being transported to the second conveying line 120 along with the circuit board. This helps to prevent the etching solution from accumulating and causing adverse effects on the circuit board.

[0042] It should be understood that in some other embodiments, the upper and lower walls of the receiving groove 311 are provided with a plurality of rollers 312 arranged from the outside to the inside. The circuit board etching device uses the rollers 312 to roll into or out of the upper or lower end face of the circuit board, thereby reducing the problem of the circuit board getting stuck and failing to enter or exit the receiving groove 311.

[0043] Reference Figure 1 , Figure 2 and Figure 3 As shown, it should be understood that in some other embodiments, the rotating disk 310 includes a rotating shaft, a first sub-disc and a second sub-disc arranged at a left-right interval, the rotating shaft passing through the first sub-disc and the second sub-disc, and a first rotary driver 330 driving the rotating shaft to rotate so that the first sub-disc and the second sub-disc rotate together. Both the first sub-disc and the second sub-disc have notches arranged in a centrally symmetrical manner, and the notches on the first sub-disc and the notches on the second sub-disc together form a receiving groove 311.

[0044] Reference Figure 1 , Figure 2 and Figure 3 As shown, when the circuit board is placed into the receiving groove 311, the etching solution can flow away from the gap between the first sub-disk and the second sub-disk. That is, the receiving groove 311 is hollowed out to facilitate the separation of excess etching solution from the circuit board.

[0045] Reference Figure 1, Figure 2 and Figure 3 As shown, it can be understood that in this embodiment, the etching component 200 includes a first spray component 210 and a second spray component 220, which are respectively disposed above the first conveying line 110 and the second conveying line 120.

[0046] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the first spraying component 210 includes a second support and a plurality of first spray heads 211. The second support is mounted above the first conveyor line 110, and the plurality of first spray heads 211 are connected to the second support and positioned facing the first conveying surface 111 of the first conveyor line 110. Under the conveying action of the first conveyor line 110, the circuit board is moved to the area below the first spraying component 210. An external water pump is connected to the plurality of first spray heads 211 to spray the etching solution onto the upper surface of the circuit board.

[0047] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the second spray component 220 includes a third support and a plurality of second spray heads 221. The third support is mounted above the second conveyor line 120, and the plurality of second spray heads 221 are connected to the third support and are positioned facing the second conveying surface 121 of the second conveyor line 120. Under the conveying action of the second conveyor line 120, the circuit board is moved to the area below the second spray component 220. An external water pump is connected to the plurality of second spray heads 221 to spray the etching solution onto the upper surface of the flipped circuit board.

[0048] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the circuit board etching apparatus also includes a fan 400, a second spray component 220 and the fan 400 arranged along a first direction, the fan 400 being positioned above the second conveyor line 120 for blowing air onto the circuit board located on the second conveyor line 120.

[0049] Reference Figure 1 , Figure 2 and Figure 3 As shown, after the second spraying component 220 finishes spraying the circuit board on the second conveying surface 121, the circuit board continues to be conveyed in the first direction along the second conveying line 120. After a preset length or time, the circuit board can be moved to the area below the fan 400. The fan 400 can blow air towards the circuit board on the second conveying surface 121, thereby blowing away the etching liquid accumulated on the upper surface of the circuit board, so that the etching liquid on the upper surface of the circuit board is more uniform.

[0050] It should be understood that in some other embodiments, the etching assembly 200 includes a fourth support, an upper spray member and a lower spray member, which are respectively disposed above and below the first conveyor line 110 for spraying etching liquid onto the upper and lower surfaces of the circuit board located on the first conveyor line 110.

[0051] The upper spraying component includes multiple third spray heads with downward openings, and the lower spraying component includes multiple fourth spray heads with upward openings. Both the upper and lower spraying components are connected to the fourth bracket. When the circuit board passes through the upper and lower spraying components, the upper and lower spraying components can simultaneously spray the upper and lower surfaces of the circuit board to achieve etching of the upper and lower surfaces of the circuit board.

[0052] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that in this embodiment, both the first conveyor line 110 and the second conveyor line 120 include two conveying components 130 arranged at intervals along a second direction. The second direction is arranged at right angles to the first direction. The conveying component 130 includes a belt 131 and at least two pulleys 132. The belt 131 is wound between the two pulleys 132.

[0053] Reference Figure 1 , Figure 2 and Figure 3 As shown, the upper surfaces of the two conveying components 130 of the first conveyor line 110 together define the first conveying surface 111, and the circuit board is conveyed linearly by the rotational motion of the belt 131. The upper surfaces of the two conveying components 130 of the second conveyor line 120 together define the second conveying surface 121, and the circuit board is conveyed linearly by the rotational motion of the belt 131.

[0054] Reference Figure 1 , Figure 2 and Figure 3 As shown, both the first conveyor line 110 and the second conveyor line 120 include a drive shaft extending to the left and right at both ends. The left and right ends of the drive shaft are connected to the pulleys 132 of the two conveying components 130, respectively. Under the transmission action of the drive shaft, the two conveying components 130 are rotated synchronously, which helps to improve the stability of the circuit board conveying.

[0055] Reference Figure 1 , Figure 2 and Figure 3 As shown, it is understood that the circuit board etching apparatus also includes a second rotary driver, and both the second rotary driver and the first rotary driver 330 can be rotary motors. The second rotary driver is used to drive the first conveyor line 110 and the second conveyor line 120 to rotate synchronously.

[0056] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the circuit board etching apparatus also includes a first transmission belt and a second transmission belt. A transmission wheel is connected to the conveyor shaft of the second rotary driver. One end of the first transmission belt is connected to the drive shaft of the first conveyor line 110, and the other end is connected to the transmission wheel. One end of the second transmission belt is connected to the transmission wheel of the second conveyor line 120, and the other end is connected to the transmission wheel. Under the driving action of the second rotary driver, the first and second transmission belts can be driven to rotate synchronously, so as to realize the conveying of the circuit board by the first conveyor line 110 and the second conveyor line 120. This helps to save the manufacturing cost of the circuit board etching apparatus and ensures the synchronicity of the first conveyor line 110 and the second conveyor line 120.

[0057] Reference Figure 1 , Figure 2 and Figure 3 As shown, one embodiment of the present invention is a production line including the production line shown in any of the above embodiments.

[0058] The conveying assembly 100 includes a first conveying line 110 and a second conveying line 120 arranged at intervals. The first conveying line 110 and the second conveying line 120 can sequentially convey circuit boards so that the circuit boards are conveyed along a first direction. The etching assembly 200 is used to spray etching liquid onto the circuit boards on the first conveying line 110 and / or the second conveying line 120 to etch the circuit boards. The circuit board etching apparatus also includes a flipping assembly 300, which is disposed between the first conveying line 110 and the second conveying line 120. The flipping assembly 300 includes a first rotation... The drive 330 and the rotating disk 310 have two centrally symmetrical receiving slots 311 for accommodating circuit boards. Since the conveying surface of the first conveyor line 110 is higher than the conveying surface of the second conveyor line 120, the rotation of the rotating disk 310 by the first rotary drive 330 allows the upper end of one receiving slot 311 to connect with the tail end of the first conveyor line 110, and the lower end of the other receiving slot 311 to connect with the beginning end of the second conveyor line 120. When the circuit board is conveyed from the beginning to the end of the first conveyor line 110, due to the accommodating slots... The slot 311 is open outwards, and the opening of the slot 311 gradually narrows from the outside to the inside to facilitate the alignment of the circuit board with the slot 311. This allows the circuit board to slide down the slope of the inner edge of the slot 311, enabling it to engage with the slot 311. The first rotary driver 330 can drive the rotary disk 310 to rotate 180 degrees clockwise, causing the positions of the two slots 311 to be exchanged. This results in the slot 311 containing the circuit board having its opening facing downwards, allowing the circuit board to slide down the inner edge of the slot 311 to the second conveyor line 120. At the first end, the circuit board is automatically flipped to facilitate double-sided etching. The second conveyor line 120 can continue to transport the circuit board, avoiding the problem of etching solution accumulating on one side of the circuit board. Furthermore, the layout of the rotating disk 310 with the first conveyor line 110 and the second conveyor line 120 ensures a smoother transition of the circuit board between the rotating disk 310 and the first and second conveyor lines 110 and 120. This helps improve the accuracy of circuit board transport and flipping, and helps avoid problems such as circuit board accumulation, jamming, or flipping failure.
