[0001] This utility model relates to the field of PCB manufacturing technology, and in particular to an auxiliary material testing device used in PCB manufacturing. Background Technology

[0002] With the continuous development of society and the continuous progress of technology, the technology related to PCB board manufacturing is also constantly improving. In the PCB printed circuit board manufacturing industry, the incoming material inspection (IPQC) scope of the water-absorbing sponge roller used as an auxiliary material on the horizontal processing production line has always been a blank area. The incoming material inspection only focuses on visual confirmation of damage and defects.

[0003] The patent document with publication number "CN211013920U" discloses an auxiliary material testing device for PCB manufacturing, including an operating platform and a measuring cup, wherein the measuring cup is fixed on the top surface of the operating platform.

[0004] Although the aforementioned patent documents have solved the problems of not being able to effectively inspect the quality of the absorbent sponge roller and increasing the workload of experimental personnel, they still have the following drawbacks: after the DI water in the measuring cup is reduced due to testing, it is inconvenient to quickly add a new appropriate amount of DI water to the measuring cup, making the operation relatively inconvenient and not conducive to the use of the testing device. Utility Model Content

[0005] The purpose of this invention is to address the following shortcomings in the prior art: after the DI water in the measuring cup is reduced due to testing, it is inconvenient to quickly add a new and appropriate amount of DI water to the measuring cup, making the operation inconvenient and detrimental to the use of the testing device. Therefore, this invention proposes an auxiliary material testing device for PCB manufacturing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A PCB manufacturing auxiliary material testing device includes an operating platform and a measuring cup set on the operating platform. A measuring cylinder is fixedly connected to one side of the measuring cup, and an inlet tube is inserted into the measuring cup. A vertical plate is fixedly connected to the operating platform, and a T-shaped plate and an electric push rod are fixedly connected to one side of the vertical plate. A rack plate is slidably connected to the T-shaped plate, and an installation cavity is formed inside the rack plate. A T-shaped rod is slidably connected inside the installation cavity. The drive end of the electric push rod is fixedly connected to the T-shaped rod. A rotating assembly is provided on the liquid inlet pipe. The rotating assembly includes a sealing plate rotatably installed inside the liquid inlet pipe. A rotating shaft is fixedly connected to the sealing plate. A gear is fixedly connected to the rotating shaft. The gear meshes with the rack plate. A hollow shell is fixedly connected to the upper surface of the measuring cylinder. A moving assembly is provided on the hollow shell.

[0007] Preferably, the movable component includes a rectangular plate slidably installed inside the hollow shell, a bending rod fixedly connected to one side of the rectangular plate, a first spring sleeved on the bending rod, one end of the first spring being fixedly connected to the bending rod, and the other end of the first spring being fixedly connected to the inner wall of the hollow shell.

[0008] Preferably, a support ring is fixedly connected inside the measuring cylinder, a float plate is provided above the support ring, an air inlet and an air outlet are provided on the measuring cylinder, a circular hole communicating with the air outlet is provided on the lower inner wall of the hollow shell, a one-way valve is provided in both the air inlet and the air outlet, and an exhaust port is provided on one side of the inner wall of the hollow shell.

[0009] Preferably, an L-shaped rod is fixedly installed on one side of the T-shaped rod, and a sealing plate is fixedly connected to one end of the L-shaped rod.

[0010] Preferably, a slide rod is slidably connected to the vertical plate, and a return spring is sleeved on the slide rod. One end of the return spring is fixedly connected to the slide rod, and the other end of the return spring is fixedly connected to the vertical plate.

[0011] Preferably, the T-shaped plate has a groove for the rack plate to slide back and forth, and the side surface of the rack plate and the surface of the T-shaped plate are in contact.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When the DI water in the measuring cup needs to be replenished due to reduced usage during testing, the electric push rod is activated. The electric push rod drives the T-shaped rod to slide within the mounting cavity of the rack plate. The sealing plate seals and blocks the vent. As the T-shaped rod continues to move in the same direction, the sealing plate continues to seal and block the vent. The T-shaped rod then moves against the inner wall of one side of the mounting cavity, which drives the rack plate to slide along the groove of the T-shaped plate. The sealing plate changes from a horizontal state to an inclined state, opening the inlet pipe channel. DI water can then be delivered to the measuring cup and measuring cylinder through the inlet pipe. The float plate moves upward in the measuring cylinder, squeezing the air in the measuring cylinder and allowing it to enter the hollow shell. When the bending rod squeezes the sliding rod, the electric push rod drives the T-shaped rod back to its initial position. At this time, the measuring cylinder and measuring cup contain a new and appropriate amount of DI water. The operation is relatively simple and quick, which is beneficial to the use of the testing device and improves the ease of use and practicality of the PCB manufacturing auxiliary material testing device.

[0017] Reference Figures 1-5 A PCB manufacturing auxiliary material testing device includes an operating platform 1 and a measuring cup 2 mounted on the operating platform 1. A measuring cylinder 6 is fixedly connected to one side of the measuring cup 2, and an inlet pipe 3 is inserted into the measuring cup 2. A vertical plate 7 is fixedly connected to the operating platform 1. A T-shaped plate 9 and an electric push rod 11 are fixedly connected to one side of the vertical plate 7. A rack plate 10 is slidably connected to the T-shaped plate 9. An installation cavity is opened in the rack plate 10, and a T-shaped rod 12 is slidably connected in the installation cavity. The drive end of the electric push rod 11 is fixedly connected to the T-shaped rod 12. A rotating assembly is provided on the inlet pipe 3. The rotating assembly includes a sealing plate 18 rotatably mounted inside the inlet pipe 3. A rotating shaft is fixedly connected to the sealing plate 18, and a gear 8 is fixedly connected to the rotating shaft. The gear 8 and the rack plate 10 are meshed. A hollow shell 4 is fixedly connected to the upper surface of the measuring cylinder 6, and a moving assembly is provided on the hollow shell 4.

[0018] refer to Figure 3The moving component includes a rectangular plate 15 slidably installed inside the hollow shell 4. A bent rod 5 is fixedly connected to one side of the rectangular plate 15. A first spring 14 is sleeved on the bent rod 5. One end of the first spring 14 is fixedly connected to the bent rod 5, and the other end of the first spring 14 is fixedly connected to the inner wall of the hollow shell 4. A support ring 20 is fixedly connected inside the measuring cylinder 6. A float plate 19 is provided above the support ring 20. The measuring cylinder 6 has an air inlet and an air outlet. The lower inner wall of the hollow shell 4 has a section connected to the air outlet. One-way valves are installed in the through round hole, air inlet and air outlet. An exhaust port 17 is opened on one side of the inner wall of the hollow shell 4. When the smaller float 19 moves up in the measuring cylinder 6, the float 19 has good sealing when connected to the inner wall of the measuring cylinder 6, which can squeeze the air in the upper part of the measuring cylinder 6 and let it enter the hollow shell 4. The rectangular plate 15 has good sealing when connected to the inner wall of the hollow shell 4. The rectangular plate 15 and the bent rod 5 slide relative to the hollow shell 4 at the same time, and the first spring 14 deforms.

[0019] refer to Figure 4 An L-shaped rod 21 is fixedly installed on one side of the T-shaped rod 12. A sealing plate 16 is fixedly connected to one end of the L-shaped rod 21. The drive end of the electric push rod 11 extends out and drives the T-shaped rod 12, which is fixedly connected to it, to slide in the mounting cavity of the rack plate 10. That is, the T-shaped rod 12 slides relative to the rack plate 10, and the L-shaped rod 21 moves at the same time. After the sealing plate 16 moves, it will seal and block the exhaust port 17.

[0020] refer to Figure 4 A slide rod 13 is slidably connected to the vertical plate 7. A return spring is sleeved on the slide rod 13. One end of the return spring is fixedly connected to the slide rod 13, and the other end of the return spring is fixedly connected to the vertical plate 7. When the bending rod 5 gradually moves and squeezes the slide rod 13, the electric push rod 11 drives the T-shaped rod 12 back to the initial position, that is, the sealing plate 16 is misaligned with the exhaust port 17, and the sealing plate 18 re-seals and blocks the liquid inlet pipe 3.

[0021] refer to Figure 3 The T-shaped plate 9 has a groove for the rack plate 10 to slide back and forth. The side surface of the rack plate 10 is in contact with the surface of the T-shaped plate 9. The drive end of the electric push rod 11 extends out and drives the T-shaped rod 12, which is fixedly connected to it, to slide in the mounting cavity of the rack plate 10. That is, the T-shaped rod 12 slides relative to the rack plate 10. As the T-shaped rod 12 continues to move in the same direction, it will move against the inner wall of the other side of the mounting cavity, which will drive the rack plate 10 to slide along the groove of the T-shaped plate 9.

[0022] In this invention, in the initial state, the sealing plate 16 and the exhaust port 17 are misaligned. At this time, the side surface of the rack plate 10 is in contact with the side surface of the T-shaped plate 9, and the sealing plate 18 is in a horizontal state to seal and block the liquid inlet pipe 3. At this time, the T-shaped rod 12 is in contact with one side of the inner wall of the mounting cavity. When the DI water in the measuring cup 2 needs to be replenished due to the decrease in detection usage, the electric push rod 11 is activated. The drive end of the electric push rod 11 extends, driving the T-shaped rod 12, which is fixedly connected to it, to slide within the mounting cavity of the rack plate 10, that is, the T-shaped rod 12 and the rack plate 10 slide relative to each other. As the L-shaped rod 21 moves, the sealing plate 16 moves and seals the exhaust port 17. As the T-shaped rod 12 continues to move in the same direction, the sealing plate 16 keeps the exhaust port 17 sealed. The T-shaped rod 12 then moves against the inner wall of the other side of the mounting cavity, which drives the rack plate 10 to slide along the groove of the T-shaped plate 9. Because the rack plate 10 is meshed with the gear 8, the gear 8 rotates. The gear 8 drives the sealing plate 18 in the liquid inlet pipe 3 to rotate through the rotating shaft. The sealing plate 18 changes from a horizontal state to an inclined state, opening the liquid inlet pipe 3 channel.

[0023] The inlet pipe 3 is connected to a DI water storage tank (not shown). DI water from the storage tank can then be transported through the inlet pipe 3 to the measuring cup 2 and the measuring cylinder 6. As the amount of DI water in the measuring cylinder 6 increases, the smaller float 19 will rise within the cylinder. The float 19 has a good seal when connected to the inner wall of the measuring cylinder 6, thus squeezing out air from the upper part of the measuring cylinder 6 and allowing it to enter the hollow shell 4. The rectangular plate 15 has a good seal when connected to the inner wall of the hollow shell 4. The rectangular plate 15 and the bent rod 5 simultaneously interact with the hollow shell 4. During relative sliding, the first spring 14 deforms. When the bending rod 5 gradually moves and squeezes the sliding rod 13, the electric push rod 11 drives the T-shaped rod 12 back to the initial position, that is, the sealing plate 16 and the exhaust port 17 are misaligned. The sealing plate 18 re-seals and blocks the liquid inlet pipe 3, completing the operation of adding DI water to the measuring cup 2. At this time, the measuring cylinder 6 and the measuring cup 2 contain a new and appropriate amount of DI water. The operation is relatively simple and quick, which is beneficial to the use of the testing device and improves the ease of use and practicality of the PCB manufacturing auxiliary material testing device.
