Description

Technical Field

[0001] The invention relates to the technical field of table tennis racket polishing equipment, and in particular to an automatic table tennis racket polishing equipment and a polishing method. Background Art

[0002] In the prior art, table tennis is a sport with a wide range of fans. A good table tennis racket is particularly important in table tennis. Table tennis rackets are mostly made of wooden materials. During the manufacturing process, they need to be polished later. However, most of the polishing methods are basically manual polishing or semi-automatic polishing, which has problems such as uneven polishing, irregular polishing, appearance deformation, poor quality, labor consumption, and high cost. Long-term manual polishing by workers will lead to a poor working environment. Workers inhale a large amount of dust and are prone to dust occupational diseases. In addition, as far as the current table tennis racket processing device is concerned, the cost is high, and the table tennis racket cannot be processed quickly. The processing accuracy is low, and the defective rate is increased. At the same time, its surface flatness is poor, and the double-sided rubber cannot be firmly attached. After bonding, the edge is prone to warping, which leads to the phenomenon that the rubber falls off due to uneven glue coating during later use, and it is very easy to overflow glue, so secondary polishing is required, which reduces the quality of quality control.

[0003] The Chinese utility model patent with application number: 202222094048.6 discloses an automatic polishing device for a table tennis racket, which consists of a main frame assembly, a swing angle sand rack assembly, a working slide assembly, a suction cup feeding assembly and a racket positioning seat assembly. The upper left side of the main frame assembly is a swing angle sand rack assembly, and the swing angle sand rack assembly includes an X-axis guide rail, and the X-axis guide rail is provided with an X-axis ball screw that cooperates with it. The X-axis ball screw and the X-axis guide rail are provided with a sand rack slide, one end of the X-axis ball screw is connected to the X-axis servo motor, and a fixed sand rack is assembled on the side of the sand rack slide, a swing angle cylinder is installed on the upper part of the fixed sand rack, and the bottom of the fixed sand rack is a swing angle sand rack. However, this type of automatic polishing device for table tennis rackets absorbs and loads the table tennis racket, and the material is prone to falling off during the loading process, and the loading stability is poor. In addition, it is unable to drive the table tennis racket to rotate during the polishing process according to the curvature of the side of the table tennis racket to achieve fine processing of the arc side of the table tennis racket, resulting in poor polishing accuracy for the table tennis racket.

During the polishing process, the two-dimensional moving structure drives the grabbing mechanism to move closer to or away from the sanding machine 31 to meet the polishing requirements of the table tennis racket. At the same time, the angle adjustment motor 29 drives the grabbing mechanism to rotate a certain angle through the angle adjustment gear 28 to drive the table tennis racket to rotate a certain angle according to the curvature of the side of the table tennis racket, so as to achieve fine processing of the arc side of the table tennis racket. In addition, the fine-tuning motor 21 during the processing process can drive the movable top column 20 to rotate a certain angle to fine-tune the polishing angle of the table tennis racket, thereby improving the polishing accuracy of the arc side of the table tennis racket;

[0046] e. After polishing is completed, the two-dimensional moving structure drives the grabbing mechanism to move to the unloading channel 32, and the holding cylinder retracts to drive the movable top column 20 to rise. The polished table tennis racket falls into the unloading channel 32 and slides out of the polishing equipment along the unloading channel 32, and the polishing process of the table tennis racket is completed.

[0047] Working principle:

[0048] When it is necessary to automatically polish the table tennis racket to be polished, start the equipment, the feeding mechanism automatically clamps and feeds the table tennis racket to be polished and transports it to the grabbing mechanism, the grabbing mechanism grabs the table tennis racket to be polished and moves to the sanding machine 31 under the action of the displacement component to polish the table tennis racket. During the polishing process, the angle adjustment motor 29 adjusts the polishing angle of the grabbing mechanism and the table tennis racket, and the fine-tuning motor 21 fine-tunes the polishing angle of the table tennis racket, thereby achieving fine polishing of the arc side of the table tennis racket. After the polishing is completed, the displacement component drives the grabbing mechanism to move to the unloading channel 32 and unloads the polished table tennis racket through the unloading channel 32 to complete the polishing process of the table tennis racket.

[0049] The beneficial effects of the present invention are that a feeding mechanism is provided, which can automatically clamp and feed the table tennis racket, and no falling off will occur during the feeding process. The feeding stability is strong. A grasping mechanism is provided to cooperate with a grinding mechanism, which can grasp the table tennis racket and drive the table tennis racket to rotate according to the curvature of the side of the table tennis racket during the grinding process to achieve fine processing of the arc side of the table tennis racket. The grinding accuracy is high. Grinding the table tennis racket by using this equipment can effectively improve the grinding accuracy and grinding efficiency of the arc side of the table tennis racket and reduce the grinding error.
