Description

Technical Field

[0001] The utility model relates to a ceramic bottom grinding machine capable of accurately feeding ceramic finished products. Background Art

[0002] The bottom of a ceramic finished product usually has a bottom edge, and the bottom edge usually has problems such as rough surface and easy to cut the user's hand. Therefore, a special bottom edge grinding device is required to process the bottom edge.

[0003] At present, the bottom edge grinding device usually uses a disc-shaped grinding wheel that rotates continuously to grind the bottom edge of the ceramic finished product. For example, a ceramic product automatic bottom grinding machine disclosed in a Chinese patent document with the publication number CN202377883U and the name "Ceramic Product Automatic Bottom Grinding Machine" includes an upper frame and a lower frame. The lower frame is provided with a circulating conveyor belt and a first motor, and the circulating conveyor belt is driven by the first motor; the upper frame is installed with a grinding disc assembly; the grinding disc assembly includes a horizontal grinding disc and a second motor for driving the horizontal grinding disc to rotate. The installation direction of the rotating shaft of the horizontal grinding disc is vertical, the rotating shaft of the horizontal grinding disc is connected to the rotating shaft of the second motor, and the horizontal grinding disc is located at the lowermost end of the grinding disc assembly; the upper frame is also provided with a vertical power mechanism for driving the grinding disc assembly to move up and down; the upper frame is fixedly installed with a first photoelectric eye device, and the grinding disc assembly is located in front of the first photoelectric eye device; a PLC programming controller is also provided. The first photoelectric eye device is connected to the PLC programming controller through a signal line, and the PLC programming controller is connected to the vertical power mechanism through a signal line.

[0004] However, the applicant found that the disadvantage of this processing equipment is that the grinding disc, that is, the disc-shaped grinding wheel, the part used for grinding is its top surface or bottom surface. Therefore, during grinding, in fact, a plane of the grinding wheel continuously rubs against the bottom edge of the ceramic finished product. Although the processing speed is relatively fast, there are many disadvantages: due to the large individual differences caused by the shrinkage of the ceramic finished product, and the lifting distance of the grinding wheel during operation is preset, it is easy to cause the situation that the grinding wheel descends to the lowest position but fails to contact the ceramic finished product or the grinding wheel presses the ceramic finished product to be damaged, and the probability is not low; the grinding accuracy is relatively low, and the bottom edge is difficult to be finely ground. In particular, the grinding wheel is difficult to grind the inner and outer sides of the bottom edge. Therefore, a smooth single curved surface or multiple curved surfaces cannot be processed, and it is difficult to meet the increasingly high quality requirements for ceramic finished products. In addition, the cost of the grinding wheel is high, and a large amount of electric energy is consumed for driving. Therefore, the manufacturing and use costs are relatively high. Moreover, the utilized area of the grinding wheel is limited, and the unutilized part is wasted.

[0005] For this reason, the applicant has improved the grinding device, enabling producers to grind the inner and outer sides of the bottom edge according to actual needs with the grinding device and at low cost. A patent was also applied for simultaneously with this application. However, the applicant found that the prior art uses a rotary intermittent transfer device to complete the transfer of ceramic finished products, and the picking and placing device uses a vacuum chuck to pick up and place the ceramic finished products. Therefore, the conveying device needs to accurately convey the ceramic finished products to the picking station to ensure that the ceramic finished products picked up by the vacuum chuck can be properly processed at other stations, such as grinding, printing bottom labels, etc. Therefore, it is necessary to improve the existing ceramic finished product input device and the picking and placing device. Summary of the Invention

[0006] The object of the present utility model is to provide a ceramic bottom grinding machine that can accurately feed ceramic finished products. This ceramic bottom grinding machine that can accurately feed ceramic finished products can accurately deliver the ceramic finished products to the picking station.

The number of grinding devices is the same as and corresponds one-to-one with the number of grinding stations. Each grinding device is arranged at the corresponding grinding station. Each ceramic finished product clamping and rotating device is respectively installed on the intermittent transfer mechanism. The ceramic finished product clamping and rotating device sucks the ceramic finished product and drives the ceramic finished product to rotate. The intermittent transfer mechanism makes intermittent rotation, carrying each ceramic finished product clamping and rotating device along the movement route of the ceramic finished products to stop at each station in sequence. The outlet of the precise feeding device for ceramic finished products is arranged at the picking station. It is characterized in that: the precise feeding device for ceramic finished products includes a movable bracket, a conveying auxiliary support plate, a driving unit, at least one precise feeding conveyor belt unit, and at least one driving roller unit. The conveying auxiliary support plate, the driving unit, and all driving roller units are respectively installed on the movable bracket.

The two ends of the transmission chain are respectively connected to the second end of the telescopic member and the first end of the spring. The second end of the spring is connected to the bottom surface of the conveying auxiliary support plate. The transmission chain meshes with the sprockets of all calibration units. When the precise feeding device for ceramic finished products conveys the ceramic finished products to the outlet, the ceramic finished products may shift during the movement. In order to ensure that the positions of the ceramic finished products are in the correct positions, the ceramic finished product calibration mechanism is also required to calibrate the positions of the ceramic finished products.

[0012] In a more preferred embodiment, each calibration unit further includes at least one synchronous calibration structure. The number of the synchronous calibration structures is the same as that of the main calibration structures and they are in one-to-one correspondence.

The other synchronous gear is coaxially fixed with the sprocket and the first swing rod of the corresponding main calibration structure, and the two synchronous gears mesh. In this way, the synchronous calibration structure can utilize the power of the corresponding main calibration structure and work synchronously with the corresponding main calibration structure.

[0013] In a preferred embodiment, the clamping and rotating device for ceramic finished products includes a mounting frame, a liftable frame, a lifting member, a driving mechanism, and at least one rotatable clamping unit. The mounting frame is installed around the intermittent transfer mechanism. The lifting member is installed on the mounting frame. The liftable frame is installed on the lifting member.

[0016] The beneficial effect of the present utility model compared with the prior art is that the precise feeding device for ceramic finished products utilizes the precise feeding conveyor belt and the conveying auxiliary support plate to cooperate with each other to achieve the precise conveying of ceramic finished products; while the ceramic finished product calibration mechanism uses multiple first calibration rods to cooperate with each other to calibrate the position of the ceramic finished product, ensuring the accuracy of the position of the ceramic finished product. Adding the second calibration rods corresponding to the first calibration rods can reduce the number of components and lower the cost. Description of the Drawings
