Description

Technical Field

[0001] The present invention relates to the technical field of circuit board drying, and particularly to a drying device and method for PCB circuit board production. Background Art

[0002] In the field of circuit board production, a circuit board is a provider of electrical connections for electronic components. When processing a circuit board, it is usually necessary to wash it with water to remove oxides on the circuit board. After washing, the circuit board usually needs to be baked to remove surface moisture, and a drying device is usually required for baking moisture.

[0003] Currently, in the drying device for circuit board processing, there are generally multiple layers of racks inside. When in use, in order to dry evenly, the circuit boards need to be placed on the surface of the racks respectively. Although this method is convenient for drying the surface of the circuit boards, the bottom surface of the circuit board in contact with the placement rack is difficult to be dried evenly and quickly, and it is also necessary to turn the circuit board over halfway, which is very inconvenient. Moreover, the air circulation inside the drying device is inconvenient, resulting in a low drying efficiency. In addition, placing the circuit boards on the surface of the racks respectively also wastes time, and the same is true when taking them out. Since multiple circuit boards need to be taken one by one during the taking and placing process, it takes a long time, resulting in more heat leakage, which is not conducive to drying the circuit boards next time.

[0004] In view of the above problems, the present invention document proposes a drying device and method for PCB circuit board production. Summary of the Invention

[0012] Preferably, the material storage component includes a storage bin, which is installed in the drying device.

The blanking plate extends into the storage bin.

[0014] Preferably, the pushing component includes a bracket mounted on the drying device. Two first electric push rods are mounted on one side of the bracket. One end of each of the two first electric push rods is fixedly connected with a fixing bar. Second switches are mounted on both the fixing bar and the bracket.

Two rubber clamps are mounted in the frame, and a circuit board is clamped between the two rubber clamps.

[0015] A method for using a drying device for PCB circuit board production includes the following steps: S1. When drying the circuit board, open the transparent door, place the circuit boards into the storage bin from above in sequence. After the placement is completed, close the transparent door, and then control the first electric push rod to push the fixing bar to move. Due to the position limitation of the second spring on the sliding rod, the fixing bar pushes the pushing plate to move through the sliding rod. The pushing plate pushes the lowermost circuit board out of the feed inlet, and one side of the circuit board is clamped and fixed by the rubber clamp. After the circuit board is fixed, by continuously applying pressure, the second spring deforms and drives the fixing bar to move, so that the second switch contacts the pushing plate. At this time, the pushing component retracts and resets. S2. During the reset process of the pushing component, the second motor drives the rotating rod to drive the first gear to rotate. The first gear is in transmission with the second gear, and the second gear drives the rotating shaft to rotate. The rotating shaft drives the two belt transmission structures to rotate. The belt transmission structures drive the clamping component to rise, so that the circuit board rises. The unclamped rubber clamp corresponds to the feed inlet again. When the pushing plate retracts to the right side of the feed inlet, at this time, the circuit board in the storage bin falls to the position of the feed inlet. When the contact rod presses another second switch following the reset of the fixing bar, at this time, the pushing component performs the pushing operation again, so as to cooperate with the turning component for cyclic feeding operation. S3. After the feeding is completed, the turning-over assembly drives the clamping assembly to continue rotating, and the circuit board rises to both the upper and lower sides of the belt drive structure for turning-over operation. Meanwhile, the drying device operates for drying operation. Secondly, the rotation of the second gear also drives the third gear, causing the third gear to drive the connecting shaft and the fan blades to rotate. The operation of the fan blades on both sides realizes the convection operation, which is beneficial to the drying operation of the circuit board. S4. After drying is completed, the second electric push rod is used to push the cross bar and the push rod to move, so that the push rod pushes the circuit board into the discharge port and locates it on the blanking plate, causing the circuit board to contact the inner wall of the discharge bin. By continuously applying pressure, relative movement occurs between the fixed bar and the push rod, pressing the third switch. At this time, the discharging assembly resets, and at the same time, the turning-over assembly operates to transfer the circuit board upward to the position of the discharge port. S5. Meanwhile, the first motor drives the first bevel gear to drive the second bevel gear, and the second bevel gear drives the screw rod and the nut for threaded transmission, causing the nut to drive the blanking plate to descend, so that the circuit board on the blanking plate is offset from the discharge port. After the discharging assembly resets, the connecting rod presses another third switch, and at this time, the discharging assembly performs pushing again, thus cooperating with the turning-over assembly and the lowering assembly for discharging operation. S6. When the blanking plate descends to squeeze the material placing table, the material placing table compresses the first spring downward. When the material placing table drives the first switch to contact the bottom rod, the alarm sounds to remind the staff to take the material.

[0016] Compared with the prior art, the present invention provides a drying device and method for PCB circuit board production, having the following beneficial effects: 1. For the drying device and method for PCB circuit board production, the pushing component can push the circuit board at the bottom layer out of the feeding port, enabling the circuit board to be clamped on the clamping component. The driving component drives the turning-over component to convey the circuit board upward for a certain distance. After the pushing component resets, the circuit board falls back to the feeding port again. In this way, the pushing component pushes the material again and cooperates with the turning-over component to perform cyclic feeding operation. During discharging, the discharging component can push the circuit board into the discharge port, and then the lowering component drives the circuit board to descend. At the same time, the discharging component resets, and the turning-over component lifts the circuit board to be discharged to correspond to the discharge port. At this time, the discharging component pushes the material again and cooperates with the lowering component and the turning-over component to perform discharging operations in sequence, thus meeting the automatic loading and unloading of the circuit board. Moreover, the opening area of the transparent door is relatively small, which can reduce the leakage of hot air and facilitate the subsequent drying operation.

[0017] 2. The drying equipment and method for PCB circuit board production drive the rotating rod to rotate through the second motor. The rotating rod drives the first gear and the second gear to transmit power. The second gear drives the rotating shaft to rotate. The rotating shaft drives the belt transmission structure to rotate, causing the belt transmission structure to drive the material clamping component to rotate, enabling the circuit board to move up and down following the belt transmission structure, evenly drying the circuit board. And when the circuit board moves to the upper and lower sides of the belt transmission structure for turning operation, it is beneficial to the drying operation of the circuit board. At the same time, during the rotation of the second gear, the second gear also transmits power to the third gear. The third gear drives the connecting shaft to rotate, and the connecting shaft drives the fan blades to rotate, causing the fan blades on both sides to rotate to realize the convection of hot air flow. Through convection, the circuit board can be fully dried, and at the same time, the drying efficiency of the circuit board can be accelerated.

[0018] 3. The drying equipment and method for PCB circuit board production stack the circuit boards above the storage bin, and then use the pusher component to push the circuit boards, so that the circuit boards are clamped on the material clamping component. Then the driving component controls the operation of the turning component. The turning component drives the circuit board to rise a certain distance. At the same time, after the pusher component resets, it pushes the circuit boards again, thereby achieving the purpose of feeding. At the same time, the turning component cooperates with the blowing component, which can not only realize the displacement drying of the circuit board but also realize the convection drying. After drying, the discharging component cooperates with the lowering component and the turning component to achieve the purpose of discharging. When the lowering component presses down on the feeding table, when the first switch contacts the bottom rod, an alarm can be given through the alarm to remind taking the materials, enabling this device to meet the requirements of automatic loading and unloading, and having the functions of improving the drying speed of the circuit board and alarming for taking materials, thereby improving the automation ability of the equipment and the efficiency of the operation.
