Description

Technical Field

[0001] This application relates to the technical field of cleaning tooling, and particularly to a PCB board cleaning mechanism. Background Art

[0002] With the wide application of electronic devices, the PCB (printed circuit board), as the core component of electronic products, undertakes important electrical connection and support functions. To ensure the quality and reliability of PCB boards, during the production process, the cleaning of PCB boards has become an essential step. The cleaning process can not only remove surface impurities and residues but also effectively improve the electrical performance and stability of PCB boards. However, with the continuous progress of technology and the increasing quality requirements of electronic devices, the PCB board cleaning technology is also constantly developing and improving.

[0003] Currently, the cleaning of PCB boards mainly adopts two methods: liquid cleaning and mist cleaning. Liquid cleaning usually uses water-based or solvent-based cleaning liquids to remove contaminants on the surface of PCB boards by means of soaking, brushing, or spraying. Mist cleaning is to use a cleaning agent (such as isopropyl alcohol) to form fine particles after atomization and clean the PCB boards. Compared with liquid cleaning, mist cleaning has the advantages of high cleaning efficiency, wide applicability, and little damage to sensitive components, and has been widely used in the production of many high-precision PCB boards.

[0004] Although the existing PCB board cleaning technology has been relatively mature, in practical applications, especially when using volatile and flammable solvents such as isopropyl alcohol for mist cleaning, there are certain safety hazards. If the cleaning equipment is poorly sealed during the cleaning process, isopropyl alcohol may volatilize and accumulate outside the cleaning equipment, increasing the risk of explosion and fire. Therefore, how to improve the safety of the cleaning process while ensuring the cleaning effect has become an urgent problem to be solved in the current PCB board cleaning technology. Utility Model Content

[0005] In order to improve the safety of the cleaning process while ensuring the cleaning effect, this application provides a PCB board cleaning mechanism. This application provides the following technical solutions:

[0006] A PCB board cleaning mechanism includes a cleaning tooling and a cleaning tank with an isopropyl alcohol cleaning component. The cleaning tooling is arranged on one side of the cleaning tank, and a cleaning port is opened on the side of the cleaning tank close to the cleaning tooling; the cleaning tooling is connected with a driving mechanism, and the driving mechanism is used to send the cleaning tooling into the cleaning port; the cleaning tooling includes a cleaning tray, a copper sleeve, and a fixing frame. The fixing frame is arranged on the driving mechanism, and the cleaning tray and the copper sleeve are arranged on the fixing frame. After the cleaning tray enters the cleaning tank, the copper sleeve blocks the cleaning port.

[0007] In a specific feasible implementation scheme, a sealing assembly is provided at the cleaning port, and the sealing assembly includes a first cylinder, a first closing plate, a second cylinder and a second closing plate, the first cylinder and the first closing plate are arranged above the cleaning port, and the second cylinder and the second closing plate are arranged below the cleaning port; the piston rod of the first cylinder is connected to the first closing plate, and the piston rod of the second cylinder is connected to the second closing plate, a first through groove is opened on the first closing plate, and a second through groove is opened on the second closing plate, and the shape of the through groove formed by the first through groove and the second through groove is the same as the shape of the copper sleeve.

[0008] In a specific possible implementation manner, a mounting plate is provided on the peripheral side of the cleaning port, and the first closing plate and the second closing plate are both slidably disposed on the mounting plate and can slide in a vertical direction.

[0009] In a specific possible implementation mode, the cleaning tool further comprises a turning cylinder, the turning cylinder is arranged on the fixing frame, and the piston rod of the turning cylinder is connected to the cleaning tray through the copper sleeve.

[0010] In a specific possible implementation manner, a stainless steel connecting rod is connected between the piston rod of the flip cylinder and the cleaning tray, and the copper sleeve is arranged at the connection between the stainless steel connecting rod and the piston rod of the flip cylinder.

[0011] In a specific possible implementation manner, a clearance groove for the clamping claws to pass through is provided on the cleaning tray.

[0012] In a specific possible implementation scheme, the driving mechanism is a slide cylinder, and the fixed frame is mounted on a slide of the slide cylinder.

[0013] In a specific possible implementation mode, the cleaning box is provided with an isopropanol concentration detector.

[0014] In summary, the beneficial effects of this application include at least:

[0015] 1) The design of the sealing component ensures that the cleaning process is completely sealed, effectively preventing the leakage and volatilization of volatile and flammable solvents such as isopropyl alcohol, reducing the risk of explosion and fire, and significantly improving the safety of the cleaning process.

[0016] 2) The copper sleeve and stainless steel connecting rod design in the cleaning tooling prevents direct contact between isopropyl alcohol and the piston rod of the flip cylinder, avoids corrosion of the key components of the equipment by the solvent, and extends the service life and stability of the equipment.

[0017] 3) A dedicated cleaning component is provided inside the cleaning tank. With the precise control of the sliding table cylinder and the flipping cylinder, efficient and uniform cleaning of the PCB board is achieved, ensuring the complete removal of impurities on the surface of the PCB board, thereby improving the cleanliness and electrical performance of the PCB board.

[0018] By setting the sealing component and the cleaning tooling, airtight cleaning is realized when using mist-like isopropyl alcohol to clean the PCB board. The sealing component consists of a closing plate driven by two cylinders, upper and lower. The cleaning tooling drives the cleaning tray to perform cleaning inside the cleaning tank through the sliding table cylinder. During the cleaning process, the sealing component ensures the airtightness of the cleaning environment, effectively preventing the volatilization and leakage of isopropyl alcohol, thereby improving the safety of the cleaning process and solving the safety hazard problems existing in the prior art during the cleaning process.

[0027] An embodiment of the present application discloses a PCB board cleaning mechanism.

[0028] Referring to Figure 1 , the PCB board cleaning mechanism includes a driving mechanism, a cleaning tooling 5, and a cleaning tank 2 with an isopropyl alcohol cleaning component. The cleaning tooling 5 and the driving mechanism are provided on one side of the cleaning tank 2. The cleaning tooling 5 is provided on the driving mechanism. A cleaning port 21 is opened on one side of the cleaning tank 2 close to the cleaning tooling 5, and a sealing component 3 is provided at the cleaning port 21. An isopropyl alcohol concentration detector is installed on the outer wall of the cleaning tank 2 for real-time detection of whether there is isopropyl alcohol leakage.

[0029] Referring to Figure 1 and Figure 2, the cleaning tooling 5 includes a cleaning tray 55, a copper sleeve 54, a stainless steel connecting rod 53, a turning cylinder 52 and a fixing bracket 51. The fixing bracket 51 is arranged on the driving mechanism. The cleaning tray 55, the copper sleeve 54, the stainless steel connecting rod 53 and the turning cylinder 52 are all horizontally installed on the fixing bracket 51. The piston rod of the turning cylinder 52 passes through the fixing bracket 51 and is connected to the stainless steel connecting rod 53. The other end of the stainless steel connecting rod 53 is fixedly connected to the cleaning tray 55. The copper sleeve 54 is sleeved on the connection part of the stainless steel connecting rod 53 and the piston rod of the turning cylinder 52. By horizontally installing the cleaning tray 55, the copper sleeve 54, the stainless steel connecting rod 53 and the turning cylinder 52 on the fixing bracket 51, the overall stability and structural compactness of the cleaning tooling 5 are ensured. This horizontal arrangement enables the acting force of the turning cylinder 52 to be directly and evenly transmitted to the cleaning tray 55, ensuring the precise movement of the tray during the cleaning process, avoiding tilting or shaking, and thus improving the cleaning effect and consistency. The copper sleeve 54 is sleeved on the connection part of the stainless steel connecting rod 53 and the piston rod of the turning cylinder 52, effectively isolating the contact between corrosive solvents such as isopropyl alcohol and the piston rod, preventing corrosion and extending the service life of the turning cylinder 52. In addition, the stainless steel connecting rod 53 itself has good corrosion resistance, further enhancing the durability of the cleaning tooling 5.

[0030] Referring to Figure 1 and Figure 2 , the cleaning tray 55 is provided with a first relief groove 551 and a second relief groove 552 for the gripper to pass through. The first relief groove 551 and the second relief groove 552 are located on both sides of the length direction of the PCB board 1. The setting of the relief grooves provides a passing space for the gripper, enabling the gripper to smoothly place the PCB board 1 on the cleaning tray 55 or remove it from the tray. In addition, the relief grooves ensure that the gripper can be accurately positioned when placing or removing the PCB board, avoiding interference or collision between the gripper and the cleaning tray 55, reducing the risk of misoperation during the operation, and lowering the damage probability to the equipment and the PCB board. The driving mechanism is a slide cylinder 4, and the fixing bracket 51 is installed on the slide of the slide cylinder 4. Other types of driving mechanisms can also be selected, and the present application does not limit the specific type of the driving mechanism.

[0031] Referring to Figure 1 and Figure 2, a sealing assembly 3 is provided at the cleaning port 21. The sealing assembly 3 includes a mounting plate 31, a first cylinder 33, a first closing plate 32, a second cylinder 35 and a second closing plate 34. The mounting plate 31 is fixedly installed on the periphery of the cleaning port 21. The first cylinder 33 and the first closing plate 32 are arranged above the cleaning port 21, and the second cylinder 35 and the second closing plate 34 are arranged below the cleaning port 21. The piston rod of the first cylinder 33 is connected to the top end of the first closing plate 32, and the piston rod of the second cylinder 35 is connected to the bottom end of the second closing plate 34. Both the first closing plate 32 and the second closing plate 34 are slidably arranged on the mounting plate 31 and can slide in the vertical direction. A first through groove 36 is formed in the first closing plate 32, and a second through groove 37 is formed in the second closing plate 34. Both the first through groove 36 and the second through groove 37 are semicircular, and the shape of the through groove formed by the first through groove 36 and the second through groove 37 is the same as the shape of the copper sleeve 54. Therefore, in practice, first, the first cylinder 33 and the second cylinder 35 are controlled to open the first closing plate 32 and the second closing plate 34. After driving the sliding table cylinder 4 to drive the cleaning tray 55 into the cleaning tank 2, then the first cylinder 33 and the second cylinder 35 are controlled to drive the first closing plate 32 and the second closing plate 34 to close. At this time, the copper sleeve 54 can just block the cleaning port 21, realizing the sealing operation of the cleaning tank 2.

[0032] In summary, the cleaning tooling 5 is driven by the sliding table cylinder 4. The cleaning tray 55, the copper sleeve 54, the stainless steel connecting rod 53 and the flipping cylinder 52 are horizontally installed on the fixing frame 51, ensuring the stability and corrosion resistance of the cleaning tooling 5. The sealing assembly 3 forms a seal by driving the upper and lower closing plates through two cylinders, and the copper sleeve 54 further enhances the sealing effect to prevent isopropyl alcohol from leaking. At the same time, an isopropyl alcohol concentration detector is equipped on the outer wall of the cleaning tank 2 to monitor in real time whether there is solvent leakage. This design effectively solves the potential safety hazards existing in the cleaning process of the prior art and provides a more stable and safe cleaning environment.

[0033] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
