Description

Technical Field

[0001] The utility model relates to the technical field of circuit board curing tanks, and particularly relates to a circuit board curing device. Background Art

[0002] In the existing circuit board processing technology, it is necessary to carry out copper deposition on the printed circuit board to be processed. The staff first cleans the surface of the circuit board to be processed, and then places the circuit board to be processed into the electroplating tank to deposit a layer of copper on the surface of the circuit board. After the existing process completes copper deposition, the circuit board needs to be placed in a curing tank for curing. The curing tank is filled with a chemical reagent solution, and the chemical reagent solution is used to prevent the copper on the surface of the circuit board from being exposed to the air and undergoing oxidation. In actual production and manufacturing, the staff first adds clean water into the curing tank, and then adds a high-concentration acid-base solution into the water tank according to the ratio for dilution. After the circuit board completes copper deposition, the stacked circuit boards are directly placed into the curing tank, and the solution in the tank is made to submerge the board surface to prevent contact with the air. Since the size and weight of each batch of circuit boards are different, it is very difficult for the staff to grasp the quantity when placing the circuit boards, which will cause the solution in the curing tank to easily overflow. The acid-base solution has certain corrosiveness, and the overflowed solution will corrode the ground and may even splash onto the skin of the staff, posing a great potential safety hazard.

[0025] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0026] In the existing circuit board processing technology, it is necessary to perform copper deposition on the printed circuit board to be processed. The staff first cleans the surface of the circuit board to be processed, and then places the circuit board to be processed into the electroplating tank to deposit a layer of copper on the surface of the circuit board. After the existing process completes copper deposition, it is necessary to place the circuit board into the curing tank for curing. The curing tank is filled with a chemical reagent solution to prevent the copper on the surface of the circuit board from being exposed to the air and undergoing oxidation. In actual production, the staff first adds clean water to the curing tank, and then adds a high-concentration acid-base solution to the water tank according to the ratio for dilution. After the circuit board completes copper deposition, the stacked circuit boards are directly placed into the curing tank, and the solution in the tank is made to submerge the board surface to prevent contact with the air. Since the size and weight of each batch of circuit boards are different, it is very difficult for the staff to grasp the quantity when placing the circuit boards, which will cause the solution in the curing tank to overflow relatively easily. The acid-base solution has certain corrosiveness, and the overflowing solution will corrode the ground and may even splash onto the skin of the staff, posing a great safety hazard.

[0027] Reference Figure 1 As shown, the circuit board curing device 1000 of the embodiment of the present invention includes a box body 100, a connecting pipe 200, and a switching valve 300. Reference Figure 1 And Figure 2 As shown, the box body 100 has a groove body 110, the notch of the groove body 110 is arranged upward, and a first partition plate 111 extending in the vertical direction is arranged in the groove body 110. The first partition plate 111 divides the groove body 110 into a first groove 120 and a second groove 130. The first partition plate 111 is provided with an overflow port 140. When the liquid in the first groove 120 is higher than the overflow port 140, the liquid in the first groove 120 can flow into the second groove 130 through the overflow port 140. The connecting pipe 200 communicates with the groove body 110 and is connected to the lower part of the box body 100. The switching valve 300 is arranged on the connecting pipe 200. The switching valve 300 is used to control the connection or disconnection between the connecting pipe 200 and the groove body 110. The switching valve 300 can be a ball valve, which is convenient for switching operations. In some embodiments, the volume of the first groove 120 is larger than that of the second groove 130, which can reduce the volume of the box body 100.

[0028] During use, first add clean water to the first groove 120 and pour in the acid-base solution for mixing, and then put the PCB board into the first groove 120. As more and more PCB boards are put in, the solution in the first groove 120 will overflow from the overflow port 140 into the second groove 130. The second groove 130 can store a certain volume of solution, preventing the solution from directly overflowing outside the box body 100, which can play a role in preventing overflow. In addition, the connecting pipe 200 can be docked with the collection box, and then the switching valve 300 is opened to recover the solution in the box body 100, avoiding waste and eliminating the need to invert the box body 100, making the recovery convenient.

[0029] Reference Figure 1 And Figure 2 As shown, according to some embodiments of the present invention, a second partition plate 134 extending in the vertical direction is arranged in the second groove 130. The second partition plate 134 divides the second groove 130 into a third groove 132 and a fourth groove 133. The overflow port 140 is located above the second partition plate 134. The height of the second partition plate 134 is less than that of the first partition plate 111, and the second partition plate 134 is perpendicular to the first partition plate 111, such that the divided second groove 130 and third groove 132 are square in shape.

[0030] Reference Figure 1As shown, according to some embodiments of the present utility model, the overflow port 140 extends in the thickness direction of the second partition 134 above the third groove 132 and above the fourth groove 133. The thickness direction of the second partition 134 is the left - right direction. When the liquid in the first groove 120 is higher than the overflow port 140, the liquid in the first groove 120 can flow into the third groove 132 or the fourth groove 133 through the overflow port 140. Specifically, it can be understood that the liquid in the first groove 120 can be simultaneously split into the third groove 132 and the fourth groove 133, which can avoid uneven distribution of the liquid in the third groove 132 and the fourth groove 133, resulting in a relatively large pressure on the second partition 134.

[0031] Refer to Figure 1 As shown, according to some embodiments of the present utility model, the second partition 134 bisects the second groove 130, so that the volume of the third groove 132 is equal to the volume of the fourth groove 133, which can evenly divide the second groove 130, ensure that the volumes of the liquid accumulated in the third groove 132 and the fourth groove 133 are approximately the same, and the pressure of the liquid on the second partition 134 is relatively balanced.

[0032] According to some embodiments of the present utility model, the first partition 111 is integrally formed with the box body 100, which is convenient for manufacturing. In some other embodiments, the first partition 111 can be an independent detachable structure, and the first partition 111 is inserted into the box body 100 through a clamping structure.

[0033] According to some embodiments of the present utility model, the second partition 134 is integrally formed with the box body 100, which is convenient for manufacturing. In some other embodiments, the second partition 134 can be an independent detachable structure, and the second partition 134 is inserted into the box body 100 through a clamping structure.

[0034] Refer to Figure 1 As shown, according to some embodiments of the present utility model, the circuit board curing device 1000 includes a trolley 400. The trolley 400 is provided with a frame 410, and the box body 100 is placed in the frame 410. The trolley 400 can be pushed, so as to drive the box body 100 to move, improve portability and facilitate the collection of circuit boards.

[0035] Refer to Figure 1 As shown, according to some embodiments of the present utility model, the number of the connecting pipes 200 is at least two. At least one connecting pipe 200 is communicated with the first groove 120, and at least one connecting pipe 200 is communicated with the second groove 130. When the second groove 130 is divided into the third groove 132 and the fourth groove 133, the connecting pipe 200 can be communicated with the third groove 132 or the fourth groove 133, which can facilitate the simultaneous recovery of the liquid medicine in the first groove 120 and the second groove 130, and avoid the liquid medicine remaining in the box body 100.
