Description

Technical Field

[0001] This utility model relates to the field of piezoelectric ceramic processing technology, specifically to a dust removal device for edge grinding in piezoelectric ceramic processing. Background Technology

[0002] Piezoelectric ceramics are a type of information-functional ceramic material that can convert mechanical energy and electrical energy into each other—the piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric and elastic properties, and have been widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors, etc. During the processing of piezoelectric ceramics, a grinding device is needed to grind the burrs on the edges and corners of the piezoelectric ceramics to make the edges and corners smoother.

[0003] While existing grinding devices can grind the edges and corners of piezoelectric ceramics, most only have one set of grinding wheels rotating for single-station grinding. Therefore, only one worker can grind multiple piezoelectric ceramics sequentially, which limits the grinding efficiency of the device. Furthermore, existing grinding devices cannot promptly transport the ground piezoelectric ceramics to the next process, requiring workers to periodically move the ground piezoelectric ceramics stacked in the collection box to the next process, thus increasing the labor intensity of workers and making them impractical. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device for edge grinding in piezoelectric ceramic processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dust-reducing device for edge grinding in piezoelectric ceramic processing includes an operating table and temporary storage boxes. Temporary storage boxes are placed on both sides of the upper surface of the operating table, and multiple piezoelectric ceramic sheets are stacked inside each box. A dual-station grinding assembly is installed on the upper surface of the operating table, allowing two workers to simultaneously grind the edges of the piezoelectric ceramic sheets. A feeding assembly is located behind the operating table to transport the ground piezoelectric ceramic sheets to the next process. The dual-station grinding assembly includes a first grinding wheel, a support box, a second grinding wheel, a drive shaft, a second support plate, a driven pulley, a drive belt, and a drive motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By starting the drive motor, the drive motor can drive the transmission shaft to rotate together through the connecting shaft, the driving pulley, the transmission belt and the driven pulley. The transmission shaft will drive the first grinding wheel and the second grinding wheel to rotate together through the first support plate and the second support plate.

The support box 38 is fixedly connected to the upper surface of the operating table 1. The support box 38 is connected to the operating table 1 by welding. The support box 38 supports the drive motor 315 and the drive shaft 311. The drive motor 315 is installed on the left side inside the support box 38. The drive motor 315 is electrically connected to an external control switch via wires. The drive motor 315 is fixed in a designated position inside the support box 38 by bolts. When working, the drive motor 315 can drive the connecting shaft 316 to rotate. The connecting shaft 316 is installed at the transmission end of the drive motor 315, and the connecting shaft 316 is connected to the drive motor 315 via a coupling. Figure 3 (As shown in the drawing), the connecting shaft 316 is connected to the drive pulley 317 by welding, and the connecting shaft 316 can support the drive pulley 317.

[0026] A drive pulley 317 is provided at the right end of the connecting shaft 316. A transmission shaft 311 is inserted and installed inside the upper side of the support box 38. The transmission shaft 311 is connected to the driven pulley 313, the follower ring 3111, the first support plate 318, and the second support plate 312 by welding. The driven pulley 313 is provided at the middle position of the annular side of the transmission shaft 311. A transmission belt 314 connects the driven pulley 313 and the drive pulley 317.

The drive shaft 311 will drive the first grinding wheel 32 and the second grinding wheel 39 to rotate together through the first support plate 318 and the second support plate 312.

[0029] Example 2:

[0030] Based on Embodiment 1, in this embodiment, by activating the servo motor 41, the servo motor 41 can drive the feeding belt 45 to the left via the active rotating roller 42, so that the workers can easily place the polished piezoelectric ceramic sheet 5 on the feeding belt 45 to be transported to the next process, thereby reducing the labor intensity of the workers.

[0031] The feeding assembly 4 includes a servo motor 41, a drive roller 42, a support platform 43, a support frame 44, a feeding belt 45, and a driven roller 46. A support platform 43 is installed behind the operating platform 1. The bottom of the support platform 43 is fixed to a designated position on the ground using expansion bolts. The support platform 43 supports the support frame 44. Support frames 44 are fixedly connected to both sides of the upper surface of the support platform 43. The support frames 44 are connected to the support platform 43 by welding. The support frame 44 supports the servo motor 41, the drive roller 42, and the driven roller 46. A servo motor is mounted on the upper side of the front end face of the support frame 44. The servo motor 41 is electrically connected to an external servo controller via wires. The drive end of the servo motor 41 is connected to an active roller 42. A driven roller 46 is installed to the left of the active roller 42. Both the active roller 42 and the driven roller 46 are rotatable. A feeding belt 45 is provided between the driven roller 46 and the active roller 42. When the servo motor 41 is working, it can drive the active roller 42 to rotate, so that the active roller 42 drives the feeding belt 45 to the left to perform a conveying action (the conveying direction of the feeding belt 45 has been drawn in the figure). The driven roller 46 can improve the conveying stability of the feeding belt 45.

[0032] Working principle: During the processing of piezoelectric ceramic sheet 5, the operator first places the temporary storage box 2 containing multiple piezoelectric ceramic sheets 5 to be ground at a designated position on the upper surface of the operating table 1 (see reference). Figure 1 After placement, the drive motor 315 is started, causing it to drive the drive pulley 317 to rotate via the connecting shaft 316. The drive pulley 317, in turn, drives the drive shaft 311 to rotate via the transmission belt 314 and the driven pulley 313. This, in turn, causes the drive shaft 311 to drive the first grinding wheel 32 and the second grinding wheel 39 to rotate via the first support plate 318 and the second support plate 312. At this point, two workers wearing protective gear can stand next to the first grinding wheel 32 and the second grinding wheel 39 respectively. They then take out the piezoelectric ceramic sheet 5 to be ground from the temporary storage box 2 and attach its edges to the lower side of the annular side of the first grinding wheel 32 and the second grinding wheel 39 for dual-station grinding and deburring. When the external industrial vacuum cleaner is started, it can sequentially suck up and reduce most of the dust inside the protective cover 33 through the connecting corrugated pipe 36, connecting pipe 35 and suction pipe 34, thus preventing the dust generated during the grinding process from being polluted by the surrounding environment and the respiratory health of the workers. During the grinding process of the piezoelectric ceramic sheet 5, the debris collection box 31 will collect most of the debris that falls off during grinding. When the servo motor 41 is started, it can drive the feeding belt 45 to the left through the active rotating roller 42, so that the workers can easily place the ground piezoelectric ceramic sheet 5 on the feeding belt 45 to be transported to the next process, thereby reducing the labor intensity of the workers.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
