DETAILED DESCRIPTION

[0027] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0028] Embodiment 1

[0029] like Figures 1 to 7As shown, an automatic conveying device for electroplating and cleaning of circuit boards comprises a rotating conveying disc 1, a plurality of conveying slides 2 are evenly installed on the top of the rotating conveying disc 1 along its own circumferential direction, a circuit board tooling mechanism is arranged on the conveying slide 2, and the circuit board tooling mechanism comprises a sliding plate 3, a flip seat 4 and a clamping seat 5, the sliding plate 3 is vertically installed on the conveying slide 2, the sliding plate 3 moves along the conveying direction of the circuit board, the flip seat 4 is rotatably installed at the bottom of the sliding plate 3, the rotation axis of the flip seat 4 is horizontally arranged, and the flip seat 4 can be deflected into the space formed by two adjacent sliding plates 3, the clamping seat 5 is installed at the bottom of the flip seat 4, and a finger cylinder 6 is arranged at the bottom of the clamping seat 5, the number of conveying slides 2 is an even number, and each adjacent two circuit board tooling mechanisms form a group, and each group of circuit boards The board fixture mechanism clamps a piece of circuit board, and the circuit board fixture mechanism is made to circulate through the rotation of the rotating conveyor disc 1. A loading mechanism, a cleaning mechanism, a rinsing mechanism and a unloading mechanism are sequentially arranged along the conveying track path of the rotating conveyor disc 1. The loading mechanism comprises a loading box 8 and a lifting plate 9. The top of the loading box 8 is open, and the circuit board is vertically placed in the loading box 8, and the circuit board is stacked along the horizontal direction. A lifting groove 10 is provided on the inner bottom wall of the loading box 8, and the lifting plate 9 is slidably adapted to the lifting groove 10, and the lifting plate 9 moves along the height direction of the loading box 8. The cleaning mechanism comprises a cleaning tank 11, and the rinsing mechanism comprises a rinsing tank 12. The unloading mechanism comprises a bottom plate 13 and a belt conveyor 14. Two groups of belt conveyors 14 are relatively arranged on the top surface of the bottom plate 13. The cleaning tank 1 1. The rinsing tank 12 and the bottom plate 13 both have the freedom to move in the vertical direction. The entire cleaning process of the circuit board is as follows: the rotating conveyor disc 1 drives the conveyor slide 2 to rotate, and the conveyor slide 2 drives the circuit board fixture mechanism thereon to rotate. Two adjacent circuit board fixture mechanisms form a group, and each group of circuit board fixture mechanisms clamps a circuit board. When one of the circuit board fixture mechanisms moves to the loading station, the lifting plate 9 moves upward, and the lifting plate 9 moves to the loading box 8 through the lifting groove 10 to lift the circuit board, thereby lifting the circuit board into the clamping space of the finger cylinder 6, and then the finger cylinder 6 acts to clamp the circuit board. The loading box 8 also has the freedom to move in the vertical direction. After the finger cylinder 6 clamps the circuit board, the loading box 8 moves downward, so that the circuit board is removed from the loading box 8. The top opening of the cleaning tank 11 is moved out, and when the circuit board moves to the top of the cleaning tank 11, the cleaning tank 11 moves upward to immerse the circuit board in the water in the cleaning tank 11, and the circuit board is preliminarily cleaned. Considering that the position where the finger cylinder 6 clamps the circuit board is blocked and cannot be cleaned, it is necessary to flip the circuit board, and the flip seat 4 drives the circuit board to deflect 90° close to the circuit board fixture mechanism in the idle state. At the same time, the flip seat 4 in the idle state deflects 90° close to the circuit board, and then the sliding plate 3 clamping the circuit board moves close to the circuit board fixture mechanism in the idle state, and the circuit board is sent into the clamping range of the finger cylinder 6 in the idle state, so that the circuit board is clamped by the circuit board fixture mechanism in the idle state. At this time, the circuit board fixture mechanism that initially clamps the circuit board is in an idle state.Then the two circuit board fixture mechanisms are reset in sequence, thereby turning the circuit board 180°, exposing the clamping position of the circuit board for cleaning, and achieving comprehensive cleaning of the circuit board; then the circuit board is transported to the top of the rinsing tank 12, and the rinsing tank 12 moves upward, so that the circuit board is located in the rinsing tank 12 for rinsing operation, and then the two circuit board fixture mechanisms cooperate again to turn the circuit board, so that the clamping position is exposed for rinsing, and achieving comprehensive rinsing of the circuit board. When the cleaning operation of the circuit board is completed, the circuit board is transported to the top of the unloading mechanism. At this time, the turning seat 4 clamping the circuit board is deflected, so that the circuit board is in a horizontal state, and then the bottom plate 13 drives the two sets of belt conveyors 14 to move upward, so that the belt conveyors 14 contact the circuit board, and the finger cylinder 6 is located between the two sets of belt conveyors 14, so that there is no interference between the unloading mechanism and the circuit board fixture mechanism. The finger cylinder 6 releases the circuit board, and the belt conveyor 14 starts at the same time, so as to transport the circuit board to the next work station. Finally, the unloading mechanism is reset, and the circuit board fixture mechanism moves to the loading mechanism to clamp the next circuit board, thereby realizing a complete circuit board cleaning operation. This cycle realizes the automatic transportation and cleaning of the circuit board, improves the cleaning efficiency, and reduces the cost. The two circuit board fixture mechanisms alternately cooperate to clamp the circuit board to realize the flipping operation of the circuit board, which can fully clean the circuit board and improve the cleaning effect of the circuit board. At the same time, the circuit board is cleaned by vertically clamping the circuit board, so that the pressure of the circuit board immersed in water is small, and the circuit board will not be squeezed, ensuring that the circuit board will not be damaged during the cleaning process. At the same time, the vertical transportation of the circuit board is convenient for draining water, so that the debris on it can fall along the water flow, and has a better cleaning effect.

Since the circuit board is in a vertical state, the water on the circuit board can quickly fall into the water receiving pool 42, and the hot air can quickly complete the drying operation of the circuit board with the help of the hot air, and the circuit board after drying is transported to the unloading mechanism for automatic unloading, so that the cleaned circuit board can be directly transported to the next workstation for processing.

During loading, the lifting cylinder 31 drives the lifting plate 9 to move upward, and the lifting plate 9 passes through the strip window 32 and the lifting groove 10 to enter the loading box 8, thereby lifting the circuit board in the loading box 8 upward, so that the circuit board enters the clamping range of the finger cylinder 6, and then the lifting cylinder 47 drives the loading box 8 to move downward, so that the circuit board is moved out of the loading box 8, and the loading process is completed. After the loaded circuit board is moved out of the loading box 8, the linear drive module 29 moves so that the next circuit board is within the lifting range of the lifting plate 9. When the next group of circuit board clamping mechanisms runs to the top of the loading box 8, the lifting cylinder 31 drives the loading box 8 to reset, and the lifting cylinder 31 moves again to lift the next circuit board to the clamping range of the finger cylinder 6, and so on.
