Description

Technical Field

[0001] This utility model relates to the field of manufacturing conductive circuits on conductive circuit carriers, and more particularly to a developing tank used in the preparation of circuits. Background Technology

[0002] In known circuit board manufacturing processes, the conductive circuit carrier in the developing tank needs to be dissolved in a developing solution to remove the dry film from the non-transparent parts, thereby exposing the copper plate area that needs to be etched.

[0003] Inside the developing tank, the transport mechanism and the conductive circuit carrier share the same space. The gear set of this type of transport mechanism has the problem of generating dust. The laid-out conductive circuit will have various "pool effects", and dust can easily remain on the wire circuit carrier. This has led to incompatibility between some wire circuit carriers that require higher cleanliness and the existing developing process. Utility Model Content

[0004] To solve the above problems, this utility model provides a developing tank for preparing conductive circuits. By isolating the gear set and the conductive circuit carrier in two independent spaces, the problem of dust residue on the conductor circuit carrier is solved.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a developing tank for preparing conductive circuits, comprising a tank body, wherein a transmission mechanism is provided in the tank body, characterized in that an isolation chamber and a spray chamber are provided in the tank body, the transmission mechanism is simultaneously distributed in the isolation chamber and the spray chamber, the gear set of the transmission mechanism is located in the isolation chamber, and the isolation chamber prevents dust from penetrating into the spray chamber.

[0006] The beneficial effects of this utility model are:

[0007] To address the aforementioned technical issues, this invention employs a compartmentalized storage method, separating the gear assembly from the spray chamber. The use of the isolation chamber and the spray chamber intentionally prevents dust from mixing into the developing solution. This separation design not only effectively reduces the concentration of impurities in the fluid but also prevents reactions between the fluid and the gear assembly, such as with the developing solution. This fundamental dust avoidance significantly improves the cleanliness of the process, thereby achieving the ultimate goal of optimizing impurity concentration and extending the service life of the gear assembly.

[0008] The aforementioned conductive circuit carriers include glass used in mobile phone displays. Dust residue on the glass can cause poor touch sensitivity, preventing the phone from issuing corresponding commands.

[0009] In this specific embodiment, the transmission mechanism includes a roller shaft, which is located in both the isolation chamber and the spray chamber. In order to reduce the formation of crystals, the spray chamber is equipped with a bearing. The roller shaft passes through the bearing and is connected to the gear set. The movement of the inner ring and steel ball of the bearing can crush and wash away the deposits attached to its surface. Compared with the traditional use of bushings, the use of bearings can reduce the amount of crystal formation.

[0010] Because the roller shaft is tilted, the side of the spray chamber is detachable for easy assembly. The side of the spray chamber includes a transmission plate, a fixed plate, and a bearing mounting seat. The bearing mounting seat is set on the transmission plate. The lower end of the transmission plate is tilted outward as a support fulcrum, so that the upper end of the transmission plate can be inserted into the fixed plate through a slot, thereby maintaining the tilted position of the transmission plate. This insertion scheme can provide support through the fixed plate and prevent fluid from flowing through the joint between the fixed plate and the transmission plate, effectively preventing fluid from flowing into the isolation chamber.

[0011] The gear set is made of plastic material. In order to ensure that the gear set is fully lubricated, the traditional way to reduce friction is to let fluid flow onto the gear set, such as through developing solution or water. This invention uses a nozzle installed in the isolation chamber, which is connected to an external water storage device. The purpose of spraying water is to ensure that the gear set is fully lubricated.

[0012] In addition, the spray chamber is located in the middle area of ​​the developing tank, with isolation chambers on both sides. In order to facilitate the operators to observe the internal working conditions in real time, observation windows are provided on the sides of the isolation chamber and the spray chamber. At the same time, in order to prevent water vapor from appearing in the observation windows of the isolation chamber, a vacuum port located below the gear set is provided in the isolation chamber to solve the problem of water vapor appearing in the observation windows through a negative pressure environment.

[0013] Inside the developing tank, there are also nozzles, a spray frame, and a reciprocating drive mechanism. There are multiple nozzles, which are mounted on the spray frame. The output end of the reciprocating drive mechanism is connected to the spray frame. By driving the spray frame to move back and forth on the glass, the developer can fully cover the glass.

[0014] The reciprocating transmission mechanism includes an eccentric wheel, a drive motor, a connecting rod, a transmission mounting base, and a bushing. The transmission mounting base is mounted on the spray frame, and the end of the spray frame is equipped with a roller. The concave surface on the roller engages with the guide roller inside the spray chamber. One end of the connecting rod is rotatably connected to the transmission mounting base, and the other end is connected to the bushing. The eccentric wheel is located inside the bushing, and the eccentric wheel and the bushing are rotatably connected. The drive motor drives the eccentric wheel to rotate through the transmission rod. The arc trajectory of the eccentric wheel causes the connecting rod to drag the spray frame to reciprocate on the guide roller. Attached Figure Description

[0028] like Figure 1-13 As shown, a developing tank for preparing conductive circuits includes a tank body 1, and a transmission mechanism 2 is provided inside the tank body 1. The tank body 1 is characterized by having an isolation chamber 100 and a spray chamber 101 inside the tank body 1. The transmission mechanism 2 is distributed in both the isolation chamber 100 and the spray chamber 101. The gear set 21 of the transmission mechanism 2 is located in the isolation chamber 100, and the isolation chamber 100 prevents dust from penetrating into the spray chamber 101.

[0029] The beneficial effects of this utility model are:

[0030] To solve the above-mentioned technical problems, this utility model adopts a compartmentalized storage method to separate the gear set 21 from the spray chamber 101. The use of the isolation chamber 100 and the spray chamber 101 deliberately avoids dust from mixing into the developer. This separation design not only effectively reduces the concentration of impurities in the fluid, but also avoids the reaction between the fluid and the gear set 21, such as the developer. This fundamental dust avoidance effect significantly improves the cleanliness of the process, thereby achieving the ultimate goal of optimizing the impurity concentration. At the same time, it also extends the service life of the gear set 21.

[0031] The aforementioned conductive circuit carriers include glass used in mobile phone displays. Dust residue on the glass can cause poor touch sensitivity, preventing the phone from issuing corresponding commands.

[0032] In this specific embodiment, the transmission mechanism 2 includes a roller shaft 22, which is located in both the isolation chamber 100 and the spray chamber 101. In order to reduce the formation of crystals, the spray chamber 101 is provided with a bearing 102. The roller shaft 22 passes through the bearing 102 and is connected to the gear set 21. The movement of the inner ring and steel ball of the bearing 102 can crush and wash away the deposits attached to its surface. Compared with the traditional use of bushings, the effect of using the bearing 102 is to reduce the amount of crystal formation.

[0033] In this embodiment, since the roller shaft 22 is inclined (the inclination of the roller shaft 22 is to solve the water pooling effect on the glass), the side of the spray chamber 101 is a detachable structure for easy assembly. The side of the spray chamber 101 includes a transmission plate 101a, a fixing plate 101b, and a bearing fixing seat 101c. The bearing fixing seat 101c is set on the transmission plate 101a. The lower end of the transmission plate 101a is inclined outward as a support fulcrum, so that the upper end of the transmission plate 101a can be embedded in the fixing plate 101b through the provided slot 101b-1, thereby maintaining the inclined position of the transmission plate 101a. This embedding arrangement can provide support force through the fixing plate 101b and prevent fluid from flowing through the joint between the fixing plate 101b and the transmission plate 101c, effectively preventing fluid from flowing into the isolation chamber 100.

[0034] The gear set 21 is made of plastic material. In order to ensure that the gear set 21 is fully lubricated, the traditional way to reduce friction is to let fluid flow onto the gear set 21 and lubricate it with developer or water. This utility model sets a nozzle 100a in the isolation chamber 100. The nozzle 100a is connected to an external water storage device. The purpose of spraying water is to ensure that the gear set 21 is fully lubricated.

[0035] In addition, the spray chamber 101 is located in the middle area of ​​the developing tank, with isolation chambers 100 on both sides. In order to facilitate the operator to observe the internal working conditions in real time, observation windows 103 are provided on the sides of the isolation chambers 100 and the spray chamber 101. At the same time, in order to prevent water vapor from appearing in the observation windows 103 inside the isolation chambers 100, a vacuum port located below the gear set 21 is provided inside the isolation chambers 100 to solve the problem of water vapor appearing on the observation windows 103 through a negative pressure environment.

[0036] Inside the developing tank, there are also nozzles 104, a spray frame 105, and a reciprocating transmission mechanism. There are multiple nozzles 104, which are mounted on the spray frame 105. The output end of the reciprocating transmission mechanism is connected to the spray frame 105. By driving the spray frame 105 to reciprocate on the glass, the developing solution can fully cover the glass.

[0037] The reciprocating transmission mechanism includes an eccentric wheel 106a, a drive motor, a connecting rod 106b, a transmission fixing seat 106c, and a bushing 106d. The transmission fixing seat 106c is mounted on the spray frame 105. The end of the spray frame 105 is provided with a roller 107. The concave surface 107-a on the roller 107 cooperates with the guide roller 108 in the spray chamber 101. One end of the connecting rod 106b is rotatably connected to the transmission fixing seat 106c, and the other end is connected to the bushing 106d. The eccentric wheel 106a is located inside the bushing 106d. The eccentric wheel 106a and the bushing 106d are rotatably connected. The drive motor drives the eccentric wheel 106a to rotate through the transmission rod 106e. The arc trajectory of the eccentric wheel 106a causes the connecting rod 106b to drag the spray frame 105 to reciprocate on the guide roller 108.

[0038] It should be noted that the above-mentioned developing tank can also be applied to circuit boards, and in other embodiments, when dissolving the dry film on the circuit board or cleaning the developing solution on the circuit board, the roller shaft can be set to a horizontal position.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
