[0021] This utility model proposes a circuit board conveying device.
[0022] Please see Figure 1 , Figure 2 and Figure 3In one embodiment of this utility model, the circuit board conveying device is applied to a developing and etching apparatus. The circuit conveying device includes a machine base 1 and a loading mechanism 2, a flipping mechanism 3, and a conveying mechanism 4 disposed on the machine base 1. The developing and etching apparatus includes a spraying mechanism. The flipping mechanism 3 includes a flipping driver 31, a rotating base 32, and a plurality of clamping components 33 disposed on the rotating base 32. The flipping driver 31 drives and connects to the rotating base 32. The plurality of clamping components 33 are arranged circumferentially around the rotating base 32. The clamping components 33 are provided with a conveying channel 331 and are used to clamp the circuit board. The conveying mechanism 4 is located below the conveying channel 331 and is provided with a sliding groove 41. The flipping driver 31 is used to drive the rotating base 32 to rotate, thereby driving the plurality of clamping components 33 to rotate, so that the conveying channel 331 of any one of the clamping components 33 has a horizontal state and a vertical state. When the conveying channel 331 of any of the clamping components 33 is in a horizontal state, the feeding mechanism 2 is used to convey the circuit board into the conveying channel 331 in the horizontal state; when the conveying channel 331 of any of the clamping components 33 is in the vertical state, the circuit board in the conveying channel 331 is slidably connected to the sliding groove 41, the spraying mechanism is used to spray etching liquid onto the circuit board in the conveying channel 331 in the vertical state, and the conveying mechanism 4 is used to drive the circuit board to be conveyed to the external device along the axial direction of the rotating seat 32.
[0023] The technical solution of this utility model uses a flip driver 31 to drive the rotating seat 32 to rotate, thereby driving multiple clamping components 33 to rotate synchronously, realizing the switching of the conveying channel 331 of any clamping component 33 between horizontal and vertical states. When the conveying channel 331 of any clamping component 33 is in a horizontal state, the feeding mechanism 2 can convey circuit boards into the conveying channel 331; when the conveying channel 331 of any clamping component 33 is in a vertical state, the circuit board in the conveying channel 331 slides and engages with the sliding groove 41, and the spraying mechanism sprays etching solution onto the circuit board in the vertical state. The conveying mechanism 4 conveys the circuit board along the axial direction of the rotating seat 32 to external equipment. The circuit board completes the development and etching processes in the vertical state, effectively reducing the circuit board's obstruction of the solution and improving the uniformity of solution utilization. This application realizes continuous feeding, development, etching, and unloading operations of circuit boards, improving the production continuity of circuit boards, thereby improving the production efficiency of circuit boards.
[0024] In this embodiment, the etching apparatus includes a spraying mechanism and a circuit board conveying device. The etching apparatus is used to perform developing and etching processes on circuit boards. The machine base 1 has a loading area 11, and a loading mechanism 2 is located in the loading area 11 of the machine base 1. The loading mechanism 2 includes a feeding driver, a first drive shaft 64, and multiple conveying rollers mounted on the first drive shaft 64. The feeding driver drives and connects to the first drive shaft 64. The feeding driver drives the first drive shaft 64 to rotate, thereby rotating the multiple conveying rollers and conveying the circuit board to the clamping assembly 33 of the flipping mechanism 3. The flipping mechanism 3 includes a flipping driver 31, a rotating seat 32, and multiple clamping assemblies 33 mounted on the rotating seat 32. The flipping driver 31 can be a motor or electric motor. The flipping driver 31 drives and connects to the rotating seat 32, and is used to drive the rotating seat 32 to rotate, thereby driving the clamping assemblies 33 to rotate. The machine tool 1 has a conveying area 12, and multiple clamping components 33 are arranged circumferentially around the rotating seat 32. At least two adjacent clamping components 33 are arranged at an angle. One of the clamping components 33 is a first clamping component 33 and is located in the loading area 11 of the machine tool 1. The first clamping component 33 and the loading mechanism 2 are both in a horizontal state, so that the first clamping component 33 has a horizontal conveying channel 331, which makes it easier for the loading mechanism 2 to convey the circuit board into the horizontal conveying channel 331. The other clamping component 33 is a second clamping component 33 and is located in the conveying area 12 of the machine tool 1. The second clamping component 33 has a vertical conveying channel 331, which makes it easier for the conveying mechanism 4 to convey the circuit board to external equipment. In one embodiment, the multiple clamping components 33 may also be configured as three or more groups. The clamping assembly 33 is provided with a transport channel 331. The clamping assembly 33 is used to clamp the circuit board, thereby making the circuit board more stable in the transport channel 331 for development, etching and transport to external equipment.
[0025] like Figure 3 As shown, in one embodiment, the conveying mechanism 4 includes a sliding wheel 42, the sliding wheel 42 is provided with the sliding groove 41, the sliding groove 41 extends along the circumference of the sliding wheel 42, and the sliding groove 41 is used for the circuit board to slide and connect with the sliding wheel 42.
[0026] In this embodiment, the conveying mechanism 4 includes a sliding wheel 42 with a sliding groove 41 extending circumferentially along the sliding wheel 42. When the circuit board is conveyed within the vertical conveying channel 331, it slides in connection with the sliding groove 41, improving the stability of the circuit board during conveying within the vertical conveying channel 331. In the radial direction of the sliding wheel 42, the outer diameter of the sliding groove 41 gradually decreases from the side near the groove opening towards the middle of the sliding wheel 42, resulting in a V-shaped cross-section of the sliding groove 41 along the vertical direction. This further ensures a more stable sliding connection between the circuit board and the sliding groove 41, improving the stability of the circuit board conveyed by the sliding wheel 42 along the axial direction of the rotating seat 32 to the external device.
[0027] like Figure 2 and Figure 3 As shown, in one embodiment, the clamping assembly 33 includes a clamping member 332, which includes a first clamping arm 3321, a second clamping arm 3322, and a connecting plate 3323. One end of the first clamping arm 3321 is connected to the rotating base 32, and the other end of the first clamping arm 3321 is connected to the connecting plate 3323. One end of the second clamping arm 3322 is connected to the rotating base 32, and the other end of the second clamping arm 3322 is connected to the connecting plate 3323. A transport channel 331 for storing circuit boards is formed between the first clamping arm 3321 and the second clamping arm 3322.
[0028] In this embodiment, the first clamping arm 3321, the second clamping arm 3322, and the connecting plate 3323 respectively limit the circuit board to prevent it from falling during flipping and conveying, thereby improving the stability of the clamping assembly 33 in holding the circuit board. Specifically, when the conveying channel 331 in the clamping assembly 33 is in a horizontal state, the conveying channel 331 on the clamping member 332 is located in the feeding mechanism 2, and the feeding mechanism 2 drives the circuit board to be etched to be conveyed into the accommodating space. The flipping mechanism 3 drives the clamping assembly 33 to rotate, so that the conveying channel 331 in the clamping assembly 33 switches from a horizontal state to a vertical state, thereby driving the circuit board to be etched to switch from a horizontal state to a vertical state, and thus causing the bottom end of the circuit board to be etched to slide against the sliding groove 41.
[0029] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the distance between the first clamping arm 3321 and the second clamping arm 3322 gradually decreases in the direction from the connecting plate 3323 toward the rotating seat 32.
[0030] In this embodiment, to further improve the stability of the clamping assembly 33 in clamping the circuit board, the present application adopts a gradually narrowing conveyor channel 331. Specifically, in the direction from the self-connecting plate 3323 toward the rotating seat 32, the distance between the first clamping arm 3321 and the second clamping arm 3322 gradually decreases, thereby making the conveyor channel 331 gradually narrow, and thus enabling the clamping assembly 33 to clamp the circuit board more stably.
[0031] like Figure 2 As shown, in one embodiment, the circuit board conveying device further includes a plurality of first rollers 5 and a plurality of second rollers 51, wherein the plurality of first rollers 5 are rotatably disposed on the first clamping arm 3321, and the plurality of second rollers 51 are rotatably disposed on the second clamping arm 3322.
[0032] In this embodiment, the present application employs multiple first rollers 5 and multiple second rollers 51 to slide and abut against the circuit board, and uses the rolling friction engagement conveying mechanism 4 provided by the first rollers 5 and second rollers 51 to convey the circuit board, thus avoiding damage to the circuit board by the first clamping arms 3321 and second clamping arms 3322 during the conveying process. The multiple first rollers 5 and multiple second rollers 51 are also used to limit the horizontal movement of the circuit board, improving the stability of the clamping assembly 33 in clamping the circuit board.
[0033] like Figure 2 As shown, in one embodiment, the circuit board conveying device further includes a conveying drive assembly 6 and a mounting bracket 61. The mounting bracket 61 is disposed on the machine base 1 and is located on one side of the feeding mechanism 2. The conveying drive assembly 6 is disposed on the mounting bracket 61 and is connected to the conveying mechanism 4. The conveying drive assembly 6 is used to drive the conveying mechanism 4 to rotate.
[0034] In this embodiment, the conveying drive assembly 6 includes a driver 62, a transmission belt 63, a second transmission shaft 66, a plurality of first transmission gears 65, a third transmission shaft, and a plurality of second transmission gears 67. The output end of the driver 62 is driven to the transmission belt 63, and the other end of the transmission belt 63 is driven to the second transmission shaft 66. The plurality of first transmission gears 65 are arranged at intervals along the axial direction of the second transmission shaft 66. One end of the third transmission shaft is driven to the first transmission gears 65 through the second transmission gears 67, and the other end of the third transmission shaft is driven to the drive end on the sliding wheel 42 through the second transmission gears 67. Driven by the driver 62, the transmission belt 63 drives the second transmission shaft 66 and the first transmission gears 65 to rotate, thereby driving the third transmission shaft and the second transmission gears 67 to rotate, and further driving the third transmission shaft and the sliding wheel 42 to rotate, thus improving the stability of the rotation of the sliding wheel 42. In order to improve the stability of the connection between the conveying drive assembly 6 and the machine base 1, this application sets the conveying drive assembly 6 to be installed in a mounting bracket 61, which is located above the sliding wheel 42.
[0035] like Figure 2 and Figure 3 As shown, in one embodiment, the sliding wheels 42 are configured as a plurality of them, and the plurality of conveying mechanisms 4 are arranged along the extension direction of the conveying channel 331.
[0036] In this embodiment, to ensure more stable circuit board transport, multiple sliding wheels 42 are provided, and multiple transport mechanisms 4 are arranged along the extension direction of the vertical transport channel 331. During the transport of the circuit board, the multiple sliding wheels 42 intermittently slide and abut against the circuit board through the sliding groove 41, thereby improving the stability of the transport mechanism 4 in transporting the circuit board.
[0037] like Figure 2 As shown, in one embodiment, the clamping components 33 are configured in four groups, and the four groups of clamping components 33 are arranged at an angle along the circumference of the rotating seat 32; and / or, the flipping mechanism 3 further includes a rotating shaft 34, and the rotating seat 32 is configured in multiple ways, with the multiple rotating seats 32 arranged along the axial direction of the rotating shaft 34.
[0038] In this embodiment, the included angle between the four sets of clamping components 33 is configured to be no less than 80° and no more than 90°, so that the four sets of clamping components 33 cooperate to form an approximately cross-shaped layout structure. In a preferred embodiment, the included angle between the four sets of clamping components 33 is set to 90°. Under the driving action of the rotating seat 32, each clamping component 33 can rotate clockwise or counterclockwise to the position of the adjacent clamping component 33, thereby realizing the alternating switching between the horizontal and vertical states of two adjacent clamping components 33, which is beneficial to realize the continuous production of circuit boards and thus improve the production efficiency of circuit boards. In order to facilitate the synchronous driving of multiple rotating seats 32, this device is provided with a flip driver 31, which is drivenly connected to the rotating shaft 34. Multiple rotating seats 32 are arranged sequentially along the axial direction of the rotating shaft 34 and are driven and linked through the rotating shaft 34. Four clamping members 332 are arranged circumferentially on each rotary table 32, and multiple clamping members 332 located on the same side along the extension direction of the conveying channel 331 together form a set of clamping assemblies 33. Thus, the four sets of clamping assemblies 33 are arranged around the outer periphery of the rotary table 32, ensuring that after each rotation of the rotary table 32, at least one set of clamping assemblies 33 is always located in the loading area 11 and the conveying area 12, thereby ensuring the continuity and stability of the circuit board processing process.
[0039] In one embodiment, the circuit board conveying device further includes a lifting assembly, which is drivenly connected to the conveying mechanism 4 and is used to drive the conveying mechanism 4 to move up and down.
[0040] In this embodiment, to accommodate circuit boards of different sizes, a lifting assembly is used to drive the conveying mechanism 4 for lifting. The lifting assembly is configured as a cylinder, and the output end of the cylinder is connected to the conveying mechanism 4 to drive the sliding wheel 42 to lift and adjust the relative position of the sliding wheel 42 and the circuit board, making it easier for the sliding groove 41 on the sliding wheel 42 to abut against the circuit board.
