[0002] Irregularly shaped PCBs refer to printed circuit boards whose shape differs from the traditional rectangular shape. They possess various special shapes such as circles, polygons, and irregular shapes, as well as non-circular irregular holes. They can better adapt to special space requirements, enabling the layout and connection of electronic components in small or irregular spaces. For example, PCBs in wearable devices such as smart bracelets and Bluetooth headsets can conform to the curves of the human body or be compactly stored.

[0003] Existing tools lack flexibility in adjusting the contact angle and force with irregularly shaped PCBs, making it difficult to meet the diverse processing needs of irregularly shaped PCBs with different shapes and requirements. Moreover, in actual operation, traditional tools are also insufficient in terms of ease of use and adaptability, failing to efficiently and accurately complete the cleaning and related processing tasks of irregularly shaped PCBs. Therefore, this application provides a ceramic brush for irregularly shaped PCBs to meet these needs. Utility Model Content

Detailed Implementation

[0022] The ceramic brush for irregularly shaped PCB boards provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art can also use other alternative methods to implement the invention; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0023] Example 1: As Figures 1 to 3 As shown, an embodiment of this utility model provides a ceramic brush for irregularly shaped PCB boards, comprising: a flexible rod 1; multiple sets of ceramic brush modules 2, all located on the flexible rod 1; the multiple sets of ceramic brush modules 2 are evenly distributed on the flexible rod 1; a connecting frame 3, located on the flexible rod 1; an electric push rod 4, located at the bottom end of the connecting frame 3; and a connecting flexible rod 5, located on the flexible rod 1, with both ends of the connecting flexible rod 5 connected to one end of the flexible rod 1, and configured to push the middle part of the connecting flexible rod 5 away from the flexible rod 1 when the electric push rod 4 is activated.

[0024] like Figures 1 to 2 As shown, it also includes: a push rod 6, located on the connecting frame 3; and a caster wheel 7, located between the push rod 6 and the connecting frame 3, and configured to rotatably connect the connecting frame 3 and the push rod 6.

[0025] like Figures 1 to 3 As shown, it also includes: a transmission block 8 located on the connecting flexible rod 5; and a circular groove 9 formed on the transmission block 8, which is configured to engage with the top of the electric push rod 4 in the circular groove 9.

[0026] like Figure 1 As shown, it also includes: an electric button 10, located on the connecting frame 3, and configured to control the extension or retraction of the electric push rod 4 via the electric button 10.

[0027] Example 2: Figures 1 to 2As shown, the connecting frame 3 is located on two sets of ceramic brush modules 2 in the middle of the multiple sets of ceramic brush modules 2.

[0028] like Figures 1 to 2 As shown, the connecting frame 3 has an opening so that the cleaning side of the multiple ceramic brush modules 2 is not blocked.

[0029] The flexible rod 1 is made of a material that is elastic and can recover its deformation. This material property allows the flexible rod 1 to flexibly conform to the shape of the complex surface contour of the irregular PCB board, ensuring that the ceramic brush always maintains good contact with the PCB board surface during operation, thereby achieving efficient cleaning or other treatment operations. Silicone rubber, thermoplastic elastomers, etc. can be used.

[0030] The connecting flexible rod 5 is made of an elastic telescopic material; this material property gives it the ability to flexibly extend and retract when subjected to force. When the electric push rod 4 is activated, the thrust it generates will push the middle part of the connecting flexible rod 5 away from the flexible rod 1, thereby adjusting the contact angle and force between the ceramic brush and the irregular PCB board to adapt to irregular PCB boards of different shapes and requirements. Rubber, polyurethane, etc. can be used.

[0031] The technical solution provided by this utility model involves moving the ceramic brush device to the vicinity of the irregularly shaped PCB board to be processed. Based on the approximate shape of the irregularly shaped PCB board, the contact angle and force between the ceramic brush and the PCB board that need to be adjusted are initially estimated. By pressing the electric button 10 on the connecting frame 3, the electric push rod 4 is controlled to extend or retract.

[0032] The top of the electric actuator 4 engages with the circular groove 9 on the transmission block 8. When the electric actuator 4 is activated, it pushes the transmission block 8, which in turn pushes the middle of the connecting flexible rod 5 to move away from the flexible rod 1 (when the electric actuator 4 extends) or towards the flexible rod 1 (when the electric actuator 4 shortens), thus achieving initial adjustment of the contact angle and force between the ceramic brush and the irregularly shaped PCB board. When the flexible rod 1 is brought close to the irregularly shaped PCB board, because the flexible rod 1 is made of an elastic material that can recover its deformation (such as silicone rubber, thermoplastic elastomers, etc.), it can automatically and flexibly conform to the shape of the complex surface contour of the irregularly shaped PCB board. During this process, the ceramic brush gradually forms good contact with the PCB board surface.

[0033] After confirming that the ceramic brush makes good contact with the surface of the irregularly shaped PCB board and that the angle and pressure are appropriate, start the ceramic brush to perform cleaning or related processing operations. Because the connecting frame 3 has an opening, the cleaning side of the multiple ceramic brush modules 2 is not blocked, which can efficiently clean irregularly shaped PCB boards and perform other operations.

[0034] If, during operation, it is found that the ceramic brush does not make good contact with certain parts of the irregular PCB board, or if the contact angle and force need to be changed according to the processing requirements, the electric push rod 4 is controlled again by the electric button 10 to adjust the position of the connecting soft rod 5 in real time, thereby changing the contact angle and force between the ceramic brush and the irregular PCB board, ensuring that the operation is carried out continuously, efficiently and accurately.

[0035] After completing the cleaning or treatment of a specific area of ​​the irregularly shaped PCB board, the electric push rod 4 is controlled by the electric button 10 to separate the ceramic brush from the irregularly shaped PCB board.

[0036] Move the ceramic brush device to the next location to be processed, and repeat the above steps until the cleaning and related processing tasks of the entire irregularly shaped PCB board are completed.

[0037] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
