Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass polishing, in particular to an automobile glass polishing device. BACKGROUND

[0002] In the field of automobile manufacturing, automobile glass is a key component for vehicle safety and comfort, and the edge polishing quality of the automobile glass is directly related to the assembly accuracy, sealing performance and impact resistance of the glass and the vehicle body. With the development of the automobile industry towards high-end and intelligentization, the market has put forward higher requirements on the size accuracy, surface quality and production efficiency of automobile glass. However, the existing automobile glass polishing technology and equipment have many problems to be solved, which seriously restricts the improvement of the production quality and manufacturing efficiency of automobile glass.

[0003] At present, most automobile glass polishing equipment adopts a rigid contact type polishing method, and the polishing assembly directly contacts the glass edge. This method is difficult to accurately control the polishing force during polishing, and it is easy to cause excessive or uneven polishing force. When the polishing force is too large, the edge of the automobile glass is easy to crack and break, which not only causes waste of raw materials, but also affects the assembly quality and safety of the whole vehicle; if the polishing force is insufficient, the expected polishing effect cannot be achieved, resulting in rough glass edge and size deviation, and reducing the product qualification rate. In addition, the large polishing impact force may also cause the glass adsorbed on the support mechanism to displace, further affecting the polishing accuracy and product consistency.

[0004] During the polishing operation, the traditional equipment needs the operator to frequently adjust the position and pressure parameters of the polishing assembly according to the actual state of the glass to prevent damage to the glass caused by excessive polishing force. This process not only consumes a lot of labor and time cost, reduces the production efficiency, and has high requirements on the experience and technology of the operator, and it is difficult to realize standardized and automated production. At the same time, frequent manual intervention also easily introduces human error, resulting in unstable product quality of different batches, which cannot meet the demand of the automobile manufacturing industry for high-precision and large-batch production.

[0005] In summary, it is an urgent task to develop an automobile glass polishing device that can accurately control the polishing force, reduce the risk of glass damage and improve the polishing accuracy, in order to promote the progress of automobile glass manufacturing technology and meet the demand of high-quality development of the automobile industry. The automobile glass polishing device of the present application is based on the above background and is born in response to the technical bottleneck in the prior art, and provides a more efficient and reliable solution for automobile glass production.

DETAILED DESCRIPTION

[0040] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0041] As Figures 1-13As shown, the automobile glass polishing device provided by the embodiment of the application comprises a base 101, a three-axis control mechanism and a driving motor 102. The three-axis control mechanism is arranged outside the base 101 and is used for controlling the accurate movement of the driving motor 102 in a three-dimensional space. An adsorption supporting mechanism for adsorbing and supporting the automobile glass is arranged above the base 101. The driving end of the driving motor 102 is drivingly connected with a square rod 103. A polishing disc 104 is arranged outside the square rod 103. A plurality of polishing discs 104 are arranged outside the polishing disc 104 at equal distances. An arc grinding groove is formed in one side of the polishing disc 104, so that the edge of the automobile glass can be polished into an arc chamfer shape. The automobile glass polishing device further comprises a fixing assembly, a gear position assembly and a connecting assembly. The fixing assembly is arranged outside the square rod 103 and is used for fixing and mounting the polishing disc 104 outside the square rod 103. The gear position assembly is arranged outside the polishing disc 104 and is used for blocking the polishing disc 105 distributed outside the polishing disc 104. The connecting assembly is arranged between the polishing disc 104 and the polishing disc 105 and is used for connecting the polishing disc 104 and the polishing disc 105 and promoting the polishing disc 105 to exert a resisting force on the inside of the gear position assembly.

[0042] When the glass sheet is cut into the shape of the automobile glass, the cut automobile glass can be placed above the base 101 and fixed by the adsorption support mechanism, and then the polishing disc 104 can be driven to rotate by the driving motor 102, and the driving motor 102 can be controlled to move accurately in three-dimensional space by the three-axis control mechanism, so as to drive the rotating polishing disc 104 to move along the edge of the automobile glass to be polished. During the movement, the polishing disc 104 is rotated with the polishing disc 104, and the polishing disc 104 is rotated with the polishing disc 104. The polishing piece 105 on the outer side of the polishing disc 104 realizes the polishing operation of the edge of the automobile glass. During the polishing process, the polishing disc 104 can be directly moved to any position in the preset polishing track by the three-axis control mechanism. At this time, the edge of the automobile glass enters the gear assembly on the outer side of the polishing disc 104 and contacts the polishing piece 105 to drive the polishing piece 105 to rotate towards the polishing disc 104. At this time, the torsion of the connecting assembly applied to the polishing piece 105 is transmitted to the edge of the automobile glass through the polishing piece 105, and the polishing force is moderate, which will not appear in the prior art. The polishing assembly directly contacts the automobile glass to cause the polishing force to be difficult to control, and the risk of causing the automobile glass to crack or the automobile glass adsorbed above the adsorption support mechanism to displace when the force is too large. At the same time, only the polishing disc 104 needs to be controlled to move according to the preset polishing track. With the continuous polishing of the edge of the automobile glass by the polishing piece 105, the position of the polishing piece 105 will also gradually recover, and when the end of the polishing piece 105 is again attached to the gear assembly, it indicates that the polishing operation of the edge of the glass has been completed. The step of frequently adjusting the position of the polishing assembly to prevent the polishing force from being too large to adversely affect the automobile glass when the polishing assembly moves along the preset track during the polishing of the automobile glass in the prior art is omitted, thereby significantly improving the polishing accuracy and achieving better use effect.
