[0027] This utility model proposes a flip-plate device.

[0028] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of this utility model, the flip-plate device is applied to a developing and etching apparatus, which includes a machine base. The flip-plate device includes a first driving device 1, a rotating component 2, and a conveying device 3. The first driving device 1 is mounted on the machine base of the developing and etching apparatus. The rotating component 2 has a first inlet 21 and a first outlet 22, and the driving end of the first driving device 1 is drivenly connected to the rotating component 2. The conveying device 3 is disposed on the rotating component 2, and the conveying device 3 has a conveying channel 31 and a second inlet 32, a second outlet 33, a first liquid outlet 34, and a second liquid outlet 35 respectively connected to the conveying channel 31. Both the first liquid outlet 34 and the second liquid outlet 35 are used to allow the liquid medicine to flow into or out of the conveying channel 31. The second inlet 32 ​​is connected to the first inlet 21, and the second outlet 33 is connected to the first outlet 22. The first inlet 21 is used to transport the workpiece to the conveying channel 31, and the first outlet 22 is used to discharge the workpiece from the conveying channel 31. The first driving device 1 is used to drive the rotating component 2 and the conveying device 3 to rotate synchronously, so that the workpiece in the conveying channel 31 is flipped.

[0029] The technical solution of this utility model uses a first driving device 1 to drive the rotating part 2 to rotate, thereby driving the conveying device 3 to rotate synchronously, and then driving the circuit board in the conveying channel 31 to rotate synchronously to adjust the position of the circuit board. The liquid flows from the first liquid outlet 34 to the second liquid outlet 35 on the outer surface of the circuit board. In order to avoid the amount of liquid on the side wall of the circuit board near the second liquid outlet 35 being less than the amount of liquid on the side wall near the first liquid outlet 34, the conveying device 3 drives the circuit board to rotate, thereby exchanging the positions of the outer side wall of the circuit board near the first liquid outlet 34 and the outer side wall near the second liquid outlet 35. The liquid is sprayed onto the side of the current circuit board near the first liquid outlet 34, so that the entire outer surface of the circuit board is exposed to the liquid for the same amount of time, which improves the problem of poor etching uniformity of the circuit board and improves the quality and reliability of the circuit board.

[0030] In this embodiment, the developing and etching apparatus can be used to perform developing and etching processes on circuit boards. The developing and etching apparatus may include a machine table and a loading assembly, a unloading assembly, and a spraying assembly mounted on the machine table. The loading assembly can be used to transport the circuit board to be electroplated through the first feed port 21 into the conveying channel 31. The unloading assembly can be used to transport the electroplated circuit board to the production equipment of the next process. Both the loading assembly and the unloading assembly may include a drive motor and a conveyor belt. The drive motor drives the conveyor belt to rotate, and the conveyor belt drives the circuit board to the conveying channel 31 or the production equipment of the next process through conveying rollers. A flipping device can be installed on the machine table, thereby enabling the flipping device to more stably flip the circuit board. The first driving device 1 may be a drive motor or other driving device. The driving end of the first driving device 1 may be fitted with a drive gear. The driving end of the first driving device 1 is driven and connected to the rotating part 2 through the drive gear to drive the rotating part 2 to rotate. The rotating part 2 may have a first feed port 21. The loading assembly is located on the side of the machine table near the first feed port 21, which makes it easier for the circuit board to be transported from the loading assembly to the flipping device. The rotating component 2 may have a first discharge port 22. The unloading assembly is located on the side of the machine near the first discharge port 22, which facilitates the transport of circuit boards in the conveying channel 31 to the unloading assembly. The conveying device 3 can be used to store circuit boards. The conveying device 3 may have a conveying channel 31, in which the circuit boards to be electroplated are transported by the loading assembly into the conveying channel 31. The spraying assembly is located above the conveying channel 31 and can be used to spray the chemical solution into the conveying channel 31 so that the chemical solution develops and etches the outer surface of the circuit board. The conveying device 3 may also have a second inlet 32, which is connected to the first inlet 21, facilitating the transport of circuit boards from the rotating component 2 into the conveying channel 31. The conveying device 3 may also have a second discharge port 33, which is connected to the first discharge port 22, facilitating the transport of circuit boards from the conveying channel 31 into the unloading assembly. Driven by the feeding assembly, the circuit board to be etched enters the conveying channel 31 through the first feed port 21 and the second feed port 32. The spraying assembly sprays the etching solution towards the conveying channel 31, and the solution contacts the circuit board to perform an etching reaction. Due to gravity, the etching solution flows downwards along the outer surface of the circuit board, resulting in a longer reaction time for the solution on the upper surface than on the lower surface. The circuit board may include a first sidewall and a second sidewall connected to each other. The first sidewall is located on the side of the circuit board near the first liquid outlet 34, and the second sidewall is located on the side of the circuit board near the second liquid outlet 35. The first driving device 1 drives the rotating component 2 to rotate, thereby rotating the conveying device 3 and the circuit board, causing the positions of the first and second sidewalls to interchange. This allows the etching solution to be sprayed onto the second sidewall, avoiding differences in the reaction time of the etching solution on the first and second sidewalls of the circuit board, and thus improving the etching effect of the etching solution on the different outer sidewalls of the circuit board.

[0031] like Figure 1 and Figure 4 As shown, in one embodiment, the rotating member 2 includes a first transmission member 23 and a turntable 24 spaced apart along a first direction. The two ends of the conveying device 3 along the first direction are detachably connected to the first transmission member 23 and the turntable 24, respectively. The conveying device 3 is located between the first transmission member 23 and the turntable 24. The driving end of the first driving device 1 is driven and connected to the first transmission member 23. The first feed port 21 is provided on the first transmission member 23, and the first discharge port 22 is provided on the turntable 24.

[0032] In this embodiment, the rotating component 2 may include a first transmission component 23 for transmission connection with the first driving device 1 and a turntable 24 for transmission connection with the machine base. The first transmission component 23 is located on the side of the conveying device 3 near the feeding component, and the turntable 24 is located on the side of the conveying device 3 near the unloading component. Specifically, the machine base may include a transmission pulley, and the outer periphery of the turntable 24 is transmissionally connected to the transmission pulley. The first transmission component 23 may be configured as a transmission gear, serving as the transmission part of the rotating component 2. The driving end of the first driving device 1 is drivenly connected to the first transmission component 23 via the drive gear, making it easier for the first driving device 1 to drive the rotating component 2 to rotate. The turntable 24 may serve as a support part of the rotating component 2, and the turntable 24 is rotatably mounted on the machine base via the transmission pulley, thereby improving the stability of the rotation of the rotating component 2. By setting the two ends of the conveying device 3 along the first direction to be detachably connected to the first transmission component 23 and the turntable 24 respectively, the rotating component 2 can drive the conveying device 3 to rotate more stably.

[0033] like Figure 1 and Figure 3 As shown, in one embodiment, the conveying device 3 includes a conveying seat 36, which includes two conveying plates 361 and a roller assembly disposed between the two conveying plates 361. The two conveying plates 361 are spaced apart in the rotating member 2 along a second direction, and the two conveying plates 361 enclose and form the conveying channel 31. The first direction intersects the second direction.

[0034] In this embodiment, the conveyor base 36 can be used to support the circuit board. The conveyor base 36 may include two conveyor plates 361 and a roller assembly disposed between the two conveyor plates 361. The two conveyor plates 361 are spaced apart from the rotating member 2 along a first direction, and the two conveyor plates 361 enclose a conveying channel 31, thereby making the circuit board move more stably within the conveying channel 31. When the circuit board is in the conveying channel 31, the roller assembly can restrict the movement of the circuit board along a second direction. The roller assembly between the two conveyor plates 361 slides against the circuit board, thereby reducing the friction of the circuit board during conveying in the conveying channel 31, and thus preventing the circuit board from being scratched during conveying in the conveying channel 31.

[0035] like Figure 1 and Figure 4 As shown, in one embodiment, the conveyor plate 361 is provided with a first connecting portion 3611 on both sides along the first direction, the first transmission member 23 is provided with a first mounting portion 231, the turntable 24 is provided with a second mounting portion 241, one side of the conveyor plate 361 is mounted to the first mounting portion 231 through the first connecting portion 3611, and the other side of the conveyor plate 361 is mounted to the second mounting portion 241 through the first connecting portion 3611.

[0036] In this embodiment, the first direction can be consistent with the front-back direction of the flip-plate device. To improve the stability of the connection between the conveyor plate 361 and the first transmission member 23, the conveyor plate 361 is provided with a first connecting portion 3611 on both sides along the first direction. The first transmission member 23 is provided with a first mounting portion 231 that matches the first connecting portion 3611. The first mounting portion 231 can be configured as a mounting groove. One side of the conveyor plate 361 is inserted into the first mounting portion 231 through the first connecting portion 3611 to securely connect the conveyor plate 361 and the first transmission member 23. To improve the stability of the connection between the conveyor plate 361 and the turntable 24, the turntable 24 is provided with a second mounting portion 241 that matches the first connecting portion 3611. The second mounting portion 241 can be configured as a mounting groove. The other side of the conveyor plate 361 is inserted into the second mounting portion 241 through the first connecting portion 3611 to securely connect the conveyor plate 361 and the turntable 24.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the flipping device further includes a second driving device 4 and a conveying roller assembly 5. The second driving device 4 is disposed on the conveying seat 36, and the conveying roller assembly 5 is disposed in the conveying channel 31. The second driving device 4 includes a first driving member 41 and a transmission assembly 42. The driving end of the first driving member 41 is driven to connect to the transmission assembly 42, and the transmission assembly 42 is driven to connect to the conveying roller assembly 5. The second driving device 4 is used to drive the transmission assembly 42 and the conveying roller assembly 5 to rotate, so that the workpiece moves along the first direction under the action of the conveying roller assembly 5.

[0038] In this embodiment, the third direction can be consistent with the up and down direction. Two sets of conveying roller assemblies 5 can be configured. The number of second driving devices 4 can be limited according to the number of conveying roller assemblies 5. Each second driving device 4 is driven and connected to one set of conveying roller assemblies 5, thereby driving the conveying roller assemblies 5 to rotate. The two sets of conveying roller assemblies 5 can be respectively located at the first liquid outlet 34 and the second liquid outlet 35 of the conveying device 3. The two sets of conveying roller assemblies 5 support the circuit board, thereby restricting the movement of the circuit board along the third direction. In this application, the first driving member 41 drives the transmission assembly 42 to rotate, thereby driving the conveying roller assemblies 5, and thus driving the circuit board on the two sets of conveying roller assemblies 5 to be conveyed along the extension direction of the conveying channel 31, improving the stability of the circuit board conveyed along the extension direction of the conveying channel 31. The conveying roller assemblies 5 can also cooperate with the roller assembly to support the circuit board, preventing the circuit board from falling off during the flipping process.

[0039] like Figure 1 and Figure 3 As shown, in one embodiment, the conveying roller assembly 5 includes a plurality of first conveying rollers 51 and a plurality of second conveying rollers 52. The first conveying rollers 51 and the second conveying rollers 52 are respectively disposed on both sides of the conveying seat 36 along a third direction. The plurality of first conveying rollers 51 are spaced apart along the first direction, and the plurality of second conveying rollers 52 are spaced apart along the first direction. The roller assembly is located between the first conveying rollers 51 and the second conveying rollers 52. The first direction, the second direction and the third direction intersect each other.

[0040] In this embodiment, multiple first conveying rollers 51 can be disposed at the first liquid outlet 34 of the conveying seat 36, and multiple second conveying rollers 52 can be disposed at the second liquid outlet 35 of the conveying seat 36, which facilitates the first conveying rollers 51 and the second conveying rollers 52 in supporting the circuit board. The multiple first conveying rollers 51 are spaced apart along the first direction, and the multiple second conveying rollers 52 are spaced apart along the first direction. The circuit board is located between the multiple first conveying rollers 51 and the multiple second conveying rollers 52. The multiple first conveying rollers 51 and the multiple second conveying rollers 52 rotate to drive the circuit board to move along the conveying channel 31, thereby improving the stability of the conveying roller assembly 5 in moving the circuit board.

[0041] like Figure 2 As shown, in one embodiment, the transmission assembly 42 includes a first transmission gear 421, a transmission shaft 422, and a second transmission gear 423 disposed on the transmission shaft 422. The first transmission gear 421 is sleeved on the transmission shaft 422. The first driving member 41 is drivenly connected to the first transmission gear 421, and the second transmission gear 423 is drivenly connected to the conveying roller assembly 5.

[0042] In this embodiment, both the first transmission gear 421 and the second transmission gear 423 can be helical gears. Multiple second transmission gears 423 can be configured, spaced apart along the extension direction of the transmission shaft 422. Each second transmission gear 423 is connected to a conveying roller assembly 5. Under the drive of the second driving device 4, the first transmission gear 421 drives the transmission shaft 422 to rotate, which in turn drives the second transmission gear 423 to rotate, thereby driving the conveying roller assembly 5 to rotate. This allows the conveying roller assembly 5 to rotate more stably under the drive of the second driving device 4.

[0043] like Figure 3 As shown, in one embodiment, the first conveying roller 51 is provided with a first groove 511 for sliding engagement with the workpiece, the first groove 511 extending circumferentially along the first conveying roller 51, and the second conveying roller 52 is provided with a second groove 521 for sliding engagement with the workpiece, the second groove 521 extending circumferentially along the second conveying roller 52.

[0044] In this embodiment, the outer diameter of the first chute 511 gradually increases from the middle of the first conveying roller 51 towards the opening of the first chute 511, so that the cross-section of the first chute 511 along the third direction can be V-shaped. The outer diameter of the second chute 521 gradually increases from the middle of the second conveying roller 52 towards the opening of the second chute 521, so that the cross-section of the second chute 521 along the third direction can be V-shaped. The circuit board is slidably connected to the first chute 511 and the second chute 521 on both sides along the third direction, so that when the first conveying roller 51 and the second conveying roller 52 rotate, they can drive the circuit board to move along the direction of the conveying channel 31, thereby improving the stability of the transmission connection between the circuit board and the first conveying roller 51 and the second conveying roller 52.

[0045] like Figure 2 and Figure 3 As shown, in one embodiment, the conveying roller assembly 5 includes a third transmission member 53 and a third transmission gear 54.

[0046] In this embodiment, the third transmission member 53 can be configured as a rotating shaft. Both the first conveying roller 51 and the second conveying roller 52 can have mounting holes. The third transmission member 53 passes through the mounting holes to enable a transmission connection between the third transmission member 53 and either the first or second conveying roller 51. The third transmission gear 54 is sleeved on one end of the third transmission member 53, facilitating a transmission connection between the first conveying roller 51 and the second transmission gear 423 via the third transmission member 53 and the third transmission gear 54, and also facilitating a transmission connection between the second conveying roller 52 and the second transmission gear 423 via the third transmission member 53 and the third transmission gear 54. The rotation of the second transmission gear 423 drives the third transmission gear 54 to rotate, which in turn drives the first conveying roller 51 to rotate via the third transmission member 53, or the second conveying roller 52 to rotate via the third transmission member 53.
