Description

Technical Field

[0001] The utility model relates to the field of circuit board processing, in particular to a device for detecting the rotation stability of a brush roll. Background Art

[0002] The ceramic plate brush line is a device used to remove burrs and resin from the surface of PCB and to grind and polish PCB. Its working principle is that the driving shaft passes through the brush stick along the central axis of the brush stick, and the driving shaft rotates at high speed to drive the brush stick, and the outer periphery of the brush stick grinds the surface of the PCB. For example, the Chinese patent with the announcement number CN220532337U discloses a cleaning device, including a conveying mechanism and a brush roller mechanism for conveying plate parts. The brush roller mechanism is on the conveying mechanism and is used to grind the plate parts. Since the driving shaft drives the brush stick by rotating at high speed, the centrifugal force is large during high-speed rotation, which will cause a deviation between the rotation trajectory of the outer periphery of the driving shaft and the standard circle, that is, the rotation trajectory of the outer periphery of the driving shaft has true roundness, which makes the rotation of the brush stick unstable. The unstable rotation of the brush stick will cause uneven grinding of the PCB, abnormal noise in the equipment, etc., so it is necessary to detect the stability of the rotation of the brush stick. The utility model provides a device for detecting the rotation stability of the brush stick in the ceramic plate brush line. Utility Model Content

[0003] The utility model overcomes the shortcomings of the above-mentioned technology and provides a device for detecting the rotation stability of a brush roller.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A device for detecting the rotation stability of a brush roller comprises an indicating measuring tool, a brush roller and a driving shaft. The driving shaft penetrates the brush roller along its central axis. The driving shaft rotates with its central axis and drives the brush roller to rotate. The indicating measuring tool is used to measure the true roundness of the rotation trajectory of the driving shaft. The smaller the true roundness of the rotation trajectory of the driving shaft, the more stable the rotation of the brush roller.

[0006] Preferably, the indicating measuring tool is a dial indicator or a micrometer, and the indicating measuring tool comprises a measuring head, and the measuring head contacts the outer wall of the driving shaft.

[0007] Preferably, the device for detecting the rotational stability of the brush roller comprises a data collector for collecting readings of an indicating measuring tool.

[0008] Preferably, the device for detecting the rotational stability of the brush roller comprises a base, and the indicating measuring tool is mounted on the base.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The utility model measures the true roundness of the rotation track of the drive shaft to judge the rotation stability of the brush stick. Since the drive shaft passes through the brush stick along the central axis of the brush stick, the drive shaft rotates with its central axis and drives the brush stick to rotate, so the true roundness of the rotation track of the drive shaft is the true roundness of the rotation track of the brush stick. The smaller the reading of the indicating measuring tool, the closer the rotation track of the drive shaft is to the standard circle, and the more stable the rotation of the brush stick is. The utility model has a simple structure for detecting the rotation stability of the brush stick and intuitively reflects the stability of the rotation of the brush stick.

[0011] 2. The indicating measuring tool is a dial indicator or a micrometer. The measuring head of the indicating measuring tool contacts the outer wall of the drive shaft, thereby measuring the true roundness of the rotation trajectory of the drive shaft. The operation is simple.

[0012] 3. The utility model collects the readings of the indicating measuring tool through the data collector, which is convenient for reading the readings of the indicating measuring tool during the high-speed rotation of the driving shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The implementation, functional features and advantages of the present invention will be further described in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0017] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0018] Reference Figure 1-3 , an embodiment of a device for detecting the rotation stability of a brush roller of the utility model is proposed:

[0019] A device for detecting the rotation stability of a brush stick, comprising an indicating measuring tool, a brush stick 1, and a driving shaft 2. The driving shaft 2 penetrates the brush stick 1 along the central axis of the brush stick 1, and the driving shaft 2 rotates with its central axis and drives the brush stick 1 to rotate. The true roundness of the rotation trajectory of the driving shaft 2 is the true roundness of the rotation trajectory of the brush stick 1. The indicating measuring tool is used to measure the true roundness of the rotation trajectory of the driving shaft 2. If the reading of the indicating measuring tool is smaller, it means that the rotation trajectory of the driving shaft 2 is closer to the standard circle, and the rotation of the brush stick 1 is more stable. If the reading of the indicating measuring tool is larger, it means that the rotation trajectory of the driving shaft 2 deviates from the standard circle, and the driving shaft 2 shakes during high-speed rotation, resulting in unstable rotation of the brush stick 1. Figure 3 As shown, the brush stick 1 rotates to remove burrs and resin on the PCB surface and polish the PCB. If the brush stick 1 rotates unstably, the PCB will be polished unevenly, affecting the quality of the PCB. Therefore, when the indication of the indicating gauge is large, it is necessary to inspect the brush stick 1 and the drive shaft 2 to avoid problems such as uneven PCB polishing by the brush stick 1, abnormal noise in the equipment, and excessive damage to the brush stick 1.

[0020] The indicating measuring tool is a dial indicator or a micrometer 3. In this embodiment, the indicating measuring tool is a micrometer 3. The micrometer 3 includes a measuring head 31, which contacts the outer wall of the driving shaft 2, so as to measure the true roundness of the rotation track of the driving shaft 2 during high-speed rotation, and the measuring operation is simple.

[0021] The micrometer 3 is used to measure the true roundness of the rotation track of the drive shaft 2. Since the drive shaft 2 rotates quickly, the reading of the micrometer 3 changes frequently, and it is difficult for the operator to read the reading only with the eyes. Therefore, the device for detecting the rotation stability of the brush roller 1 also includes a data collector, which collects the reading of the micrometer 3. The operator can know the true roundness of the rotation track of the drive shaft 2 by checking the data collector.

[0022] Therefore, the device for detecting the rotation stability of the brush roller 1 further comprises a base 32 , and the indicating measuring tool is mounted on the base 32 .

[0023] Specifically, the brush roller 1 can be a ceramic brush roller or a non-woven brush roller.

[0024] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
