[0001] This invention relates to the field of PCB brushing machine technology, specifically to high-precision PCB grinding and polishing processes, and more specifically to a quick-release structure and method for a brush bearing seat in a brushing machine. Background Technology

[0002] A board cleaning machine is an automated device used in the electronics manufacturing industry to clean the surface of circuit boards (PCBA) after soldering. It mainly removes flux, rosin, solder dross and fine particulate contaminants to ensure the board surface is clean and provides a reliable foundation for subsequent processes such as testing, applying conformal coating or assembly.

[0003] Existing brush removal machines typically use screws to fix and disassemble the side bearing housing. Disassembly requires removing the bearing housing and screws, and reinstallation is equally cumbersome and time-consuming. To address this, the inventor proposes a quick-release structure and method for the bearing housing of a brush removal machine. Summary of the Invention

[0004] The purpose of this invention is to provide a quick-release structure and method for a brush bearing seat of a brushing machine. The quick-release structure of the brush bearing seat of the brushing machine has the advantages of simple structure, reasonable design, faster brush disassembly speed compared with conventional brushing machines, reduced manual brush replacement operation time, reduced labor costs, and improved production efficiency, thus solving the problems mentioned in the above technical background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-release structure for a brush bearing seat of a brushing machine. This quick-release structure includes two body plates and a brushing device running between the two body plates. A bearing seat assembly is provided on the brushing device and locks it to one of the body plates. The bearing seat assembly is movably mounted on the quick-release device, and the brushing device is locked and disassembled by the bearing seat assembly moving on the quick-release device. The bearing seat assembly includes a bearing seat base plate and a bearing inner bushing located at the end of the bearing seat base plate away from the quick-release device. Locking nuts and a front bearing seat are respectively provided at both ends of the bearing inner bushing. The quick-release device includes a bottom support base. The device also includes a flip shaft mounted on a base support, wherein the flip shaft is horizontally positioned and a flip slider seat plate is fixedly mounted on the flip shaft. During normal use, the flip slider seat plate is in contact with the base support, and both the flip slider seat plate and the base support are horizontal. A guide rail is fixed on the flip slider seat plate, and two symmetrically arranged fixing wedges are fixed on the end of the flip slider seat plate away from the flip shaft. The fixing wedges are extensions of the flip slider seat plate. The guide rail is slidably mounted on a slider. The quick-release device also includes a locking cylinder fixed on the base support and a locking pressure block connected to the output end of the locking cylinder. The two ends of the locking pressure block are in contact with the flip slider seat plate and the fixing wedges, respectively.

[0006] Preferably, the two body plates are arranged in parallel, the bottom support is fixed on one of the body plates, and the brush plate device is symmetrically arranged between the two body plates, so that the overall structure of the brush plate device is balanced and the forces at both ends are balanced during movement.

[0007] Preferably, the brush plate device includes a brush shaft and a brush fixedly sleeved on the brush shaft. The brush is disposed between two body plates. One end of the brush shaft is mounted on a bearing bushing, and this end of the brush shaft is locked to the bearing bushing by a lock nut. The bearing bushing is disposed on one of the body plates. The other end of the brush shaft is mounted on a common bearing, which is mounted on the other body plate.

[0008] Preferably, the front bearing housing is fixed to the bearing housing base plate, and both ends of the front bearing housing are fixed with U-shaped disassembly and assembly handles. The two disassembly and assembly handles are provided for the operator to hold, so as to facilitate the movement of the entire bearing housing assembly on the quick-release device.

[0011] Preferably, two locking cylinders are distributed at both ends of the flip slider base plate, and both locking blocks are in the shape of a truncated quadrangular pyramid. The two ends of each locking block are respectively in contact with the flip slider base plate and the fixing wedge, thereby limiting the position of the flip slider base plate.

[0012] Preferably, the flip slider base plate is provided with two symmetrically distributed inclined surfaces at one end near each fixed wedge, and the two ends of the locking blocks are respectively attached to the two inclined surfaces, so that the two locking blocks lock the flip slider base plate.

[0013] This invention also provides a quick-release method for a quick-release structure of a brush bearing seat in a brushing machine, comprising the following steps: ① The two locking cylinders operate synchronously, causing the push rods on them to rise, which in turn causes the two locking blocks to disengage from the two inclined planes, so that the two locking blocks are separated from the flipping slider seat plate at the same time; ② The worker first removes the locking nut, then holds the two disassembly and assembly operation handles with both hands to move the bearing seat base plate and the two sliders horizontally on the two guide rails until the bearing inner bushing separates from the brush fixing sleeve. At this time, the two sliders will also detach from the two guide rails. ③ Flip the slider base plate 180° along the flip axis, and then remove the brush fixing sleeve and the brush in sequence.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.
