Description

Technical Field

[0001] This utility model relates to the field of ceramic brush rollers, and in particular to a ceramic brush roller chip removal assembly. Background Technology

[0002] Ceramic brush rollers are generally used in the grinding process of PCB boards. Their structure allows debris from the PCB board surface to enter the gaps. For example, the prior art with patent number CN218837398U discloses the structure of ceramic brush rollers. Therefore, in order to increase the service life and grinding efficiency of ceramic brush rollers, it is necessary to assist the ceramic brush rollers in chip removal.

[0003] However, existing ceramic brush rollers generally rely on their own chip removal gaps for chip removal. For finer chips and chips that tend to clump together, the ceramic brush roller needs to be removed and further processed after the machine is stopped. However, temporary shutdowns can disrupt the production line. Therefore, finding ways to assist in chip removal during the operation of ceramic brush rollers is a current technological trend in the field. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a ceramic brush roller chip removal component, which mainly solves the technical problem of how to achieve chip removal operation of ceramic brush rollers without stopping the machine.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model relates to a chip removal assembly for a ceramic brush roller, comprising a clamping member, a synchronous pulley located inside the clamping member, and a chip removal synchronous belt driven by the synchronous pulley. A transmission roller is connected to the middle of the synchronous pulley, and a drive motor is externally connected to the end of the transmission roller. The clamping member has through holes on its front and rear surfaces for the transmission roller to pass through. A bearing ring is installed inside the through hole, and a connector is installed on the surface of the bearing ring. A fixing member is externally connected to the end of the connector. The chip removal synchronous belt covers the upper and lower sides of the clamping member in a ring shape. The clamping member is symmetrically fixed on both sides of the gear, and both ends of the clamping member are arc-shaped. The synchronous pulley is located on both sides of the clamping member.

[0007] Preferably, the side surface of the clamping member is provided with a sliding groove, which is embedded and corresponding to the edge of the chip removal synchronous belt, and the sliding groove and the clamping member are detachably connected.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In the attached diagram, all identical reference numerals refer to the same components.

[0025] In the first embodiment, as Figure 1-4 As shown, this utility model provides a ceramic brush roller chip removal assembly, including a clamping member 1, a synchronous wheel 2 located inside the clamping member 1, and a chip removal synchronous belt 3 driven by the synchronous wheel 2. A transmission roller 4 is connected to the middle of the synchronous wheel 2, and a drive motor 5 is connected to the end of the transmission roller 4. The front and rear surfaces of the clamping member 1 are provided with through holes 6 for the transmission roller 4 to pass through. A bearing ring 7 is installed inside the through hole 6, and a connector 8 is installed on the surface of the bearing ring 7. A fixing member 9 is connected to the end of the connector 8. The chip removal synchronous belt 3 is annularly covering the upper and lower sides of the clamping member 1. The clamping member 1 is symmetrically fixed on both sides of the gear, and the two ends of the clamping member 1 are arc-shaped. The synchronous wheel 2 is located on both sides of the clamping member 1.

[0026] The chip removal component is mainly installed on the upper or lower part of the ceramic brush roller. When there are many chips inside the ceramic brush roller and they are not easy to remove, the chip removal can be continuously performed by this component. Its structure is mainly achieved by driving the motor 5 to drive the internal synchronous wheel 2. The synchronous wheel 2 then drives the chip removal synchronous belt 3 to rotate on the side surface of the clamping part 1. During the rotation process, the chip removal belt will continuously carry out the chips in the gap of the ceramic brush roller with the direction of rotation, thereby achieving the auxiliary chip removal function of the ceramic brush roller. Due to its compact structure, it can assist in chip removal without stopping the ceramic brush roller for a certain period of time when it is used with any support or gantry installation structure.

[0027] In a further embodiment, the side surface of the clamping member 1 is provided with a sliding groove 10, the sliding groove 10 is embedded and correspondingly installed with the edge of the chip removal synchronous belt 3, and the sliding groove 10 and the clamping member 1 are detachably connected.

[0028] The structure of the slide 10 is as follows Figure 2As shown, since its structure is spliced ​​and installed with the clamping component 1, such as by a detachable connection method like screws, the edge of the chip removal timing belt 3 can always maintain the front-to-back direction limit. At the same time, when the chip removal timing belt 3 becomes loose, the protruding slide groove 10 structure can be replaced to keep the chip removal timing belt 3 in a taut state.

[0029] In a further embodiment, the connecting member 8 is fixedly connected to the edge of the fixing member 9 and the bearing ring 7 respectively, and the drive motor 5 is located on one or both sides of the clamping member 1. The drive motor 5 is fixedly connected to the fixing member 9.

[0030] During the installation process, a drive motor 5 can be installed on one side of the clamping part 1 to rotate the synchronous wheel 2 on the same side, and the chip removal synchronous belt 3 can drive the synchronous wheel 2 on the other side to rotate together, thereby driving the chip removal synchronous belt 3; alternatively, the synchronous wheels 2 on both sides can be connected to drive motors 5 respectively to increase the torque of the chip removal belt and avoid hindering the rotation of the chip removal synchronous belt 3 during the rapid rotation process of the ceramic brush roller.

[0031] In another embodiment, an air pump 11 is mounted on the surface of the fixing member 9, a negative pressure port 12 is provided at the bottom of the inner side of the fixing member 9, and a chip discharge port 13 is provided at the bottom of the air pump 11; the negative pressure port 12 is located on the lower side of the chip discharge synchronous belt 3, and the chip discharge synchronous belt 3 covers half of the side surface of the clamping member 1.

[0032] The air pump 11 is mainly as follows: Figure 1 As shown, during the operation of the chip removal synchronous belt 3, the chips on both sides of the ceramic brush roller will be discharged from both sides. Therefore, a negative pressure port 12 is provided and connected to the air pump 11. The negative pressure port 12 will draw in the chips until they are discharged from the chip removal port 13. This not only concentrates the chips, but also allows the chip removal amount of the ceramic brush roller to be calculated according to the requirements of the PCB board in subsequent processes.

[0033] In a further embodiment, the inner side of the clamping member 1 is provided with a groove 14, and the side surface of the synchronous wheel 2 is slidably connected to the inner wall of the clamping member 1.

[0034] like Figure 2 As shown, this allows the timing wheel 2 to be embedded inside the clamping member 1, preventing the timing wheel 2 from coming loose.

[0035] In another embodiment, the two synchronous pulleys 2 are connected by a chip removal synchronous belt 3 for transmission. The chip removal synchronous belt 3 has a flat cross-section. The chip removal synchronous belt 3 includes a brush layer 15, an adhesive layer 16 located inside the brush layer 15, and a rubber layer 17 located inside the adhesive layer 16. The brush layer 15 is made of nylon bristles. The inner wall of the rubber layer 17 is provided with a toothed groove 18, which fits into the protrusions on the surface of the synchronous pulley 2.

[0036] Chip removal synchronous belt 3 Figure 4As shown, its structure mainly uses the brush layer 15 to penetrate into the gap of the ceramic brush roller to assist in the discharge of debris; the middle adhesive layer 16 is mainly used to fix the brush layer 15 to its surface; the inner rubber layer 17 has a toothed groove 18 on its inner wall, and the toothed groove 18 meshes with the synchronous wheel 2 to allow the synchronous wheel 2 to drive to the rubber layer 17.

[0037] Specifically, its structure is small and compact. It mainly achieves smooth discharge of small debris inside the ceramic brush roller by the lateral rotation of the chip removal synchronous belt 3, that is, when the conventional ceramic brush roller rotates axially, the chip removal synchronous belt 3 rotates laterally. Driven by rotation in different directions, the chip removal synchronous belt 3 can be smoothly discharged and avoid agglomeration.

[0038] Due to its small size and ease of disassembly, it can also be used in conjunction with a portal frame structure for auxiliary chip removal of ceramic brush rollers in long-term or short-term processes.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
