Description

Technical Field

[0001] The utility model relates to the technical field of go detection, in particular to a go piece specification detection and sorting device. Background Art

[0002] As is known, there are two main methods for processing go pieces. One is the cold processing method using mechanical cutting of natural materials, and the other is firing the go pieces into ceramic go pieces. For example, the Chinese invention patent with the announcement number CN109824266B discloses a method for manufacturing ceramic go pieces using a dry production process. Although the cold processing method processes one piece at a time, which is inefficient, the specifications of the pieces processed by automatic cutting are relatively stable and have high dimensional accuracy. Although fired ceramic go pieces can be mass-produced, the fired ceramics may have morphological differences during the high-temperature dense molding process, resulting in different specifications of the final product.

[0003] The specifications of Go pieces are mainly in terms of diameter and thickness. As for thickness, because Go pieces are generally flat, a slight difference in size will make them appear more protruding, which will further affect the feel of use. As traditional Go pieces pay more attention to usability and are usually shipped in sufficient quantities with a margin for damage, the pieces off the production line are often subject to manual caliper sampling inspection. However, with the diversity of piece materials, patterns, and designs, their collection value is gradually increasing. The quality of each piece is related to the user's purchasing experience. Therefore, the traditional method of manual caliper sampling to detect the thickness of pieces can no longer meet production needs. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" and the like indicating directions or positional relationships, they are only corresponding to the drawings of the present invention, for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction:

[0020] Combined with Figure 1-2The go piece specification detection and sorting device comprises a controller and a chess piece conveying mechanism for upside-down and upside-down circular transmission, the chess piece conveying mechanism comprises a chain ring 1, a driving sprocket 2 and a driven sprocket 3 connected by the chain ring 1, and a driving mechanism for controlling the rotation of the driving sprocket 2, the chain ring 1 is formed by hingedly connecting a plurality of chain units 101 in sequence, the conventional chain unit 101 generally comprises plates on both sides, the corresponding ends of the plates on both sides are fixed by hinge shafts, so that there is a certain gap between the plates on both sides; a bearing disk 4 is fixed to the bearing surface of the outer ring of each chain unit 101 corresponding to the chain ring 1, and a plurality of elastic clips 5 are evenly arranged and fixed on the outer edge of the upper disk surface of the bearing disk 4, the elastic clips 5 are made of rubber, silicone or elastic plastic, wear-resistant to facilitate repeated use, and the elastic clips The outer end of the strip 5 has a tendency to move toward the center of the carrier plate 4 so as to be used for clamping the outer edge of the go piece. The design length of the elastic clamping strip 5 is not long, because the lower surface of the go piece is generally an arc surface or an inverted conical truncated table. If the design is too long, it will affect the installation of the go piece by pressing it down. The design length of the elastic clamping strip 5 needs to ensure that when the go piece is pressed down, the elastic clamping strip 5 that is enclosed is broken by the arc-shaped or conical lower surface of the go piece, so that the upper end of the elastic clamping strip 5 first elastically opens outward, and then waits for the go piece to be installed in place, and then elastically resets to cling to the upper surface edge of the go piece for clamping and positioning; according to needs, a feeding robot for sucking the go piece and pressing it down to be installed on the carrier plate 4 is provided on one side of the active sprocket 2. The feeding robot is used to suck and release the go piece instead of manual feeding, which is more efficient;

[0021] A thickness detector for detecting the thickness of the go pieces is provided on one side of the upper chain segment of the chain ring 1; the existing thickness detectors are mainly divided into contact and non-contact types, both of which are relatively mature. Their detection and structural principles will not be described in detail here. According to needs, the thickness detector is set to a contact type and includes a detection reference part 10 and a detection instrument part 11 corresponding to the upper and lower surfaces of the go pieces respectively. The detection reference part 10 is connected to a lifting mechanism 12, and can be driven by the lifting mechanism 12 to press down and contact the go pieces, so that the upper chain segment of the chain ring 1 bends downward and then contacts the lower disk surface of the corresponding supporting plate 4 to the detection head of the detection instrument part 11. Of course, the actual thickness of the go piece requires the detection thickness minus the thickness of the supporting plate 4. Four points need to be noted when using and installing the detector. First, the chain ring 1 cannot be stretched too tight, resulting in no bending deformation margin. Second, the detection reference part 10 is moved up. , after the chain circle 1 is restored, neither the detection reference part 10 nor the detection instrument part 11 can contact the chain circle 1, thereby affecting the transmission movement of the chain circle 1. Thirdly, the transmission drive mechanism needs to be set to intermittent start and stop to ensure the displacement of one chain unit 101 each time. Fourthly, the gap between the two side plates of the chain unit 101 can facilitate the detection head of the detection instrument part 11 to pass through the lower disk surface of the carrier plate 4; specifically, a protrusion 6 is fixed in the center of the lower disk surface of the carrier plate 4, which enhances the structural strength of the carrier plate 4 and reduces the bending degree of the chain circle 1; in addition, the thickness detector can also be set as an infrared detector or an ultrasonic detector, and is correspondingly arranged directly above the driven sprocket 3. Since non-contact detection is generally single-sided irradiation, the chain unit 101 at the position of the driven sprocket 3 is not affected by the fluctuation of the transmission deformation of the chain circle 1, the reference is more stable, and the measurement accuracy is relatively higher;

[0022] A plurality of suction mechanisms are provided below the lower chain section of the chain ring 1 along the conveying direction, and the suction mechanism includes a suction tube 7 with an upper interval corresponding to the go pieces, and a control valve 8 is installed at the lower end of the suction tube 7, and the control valve is set as a solenoid valve, and the control valve 8 is connected to an external vacuum device through a pipeline, and a collecting tank 9 is provided directly below the suction tube 7, and the go pieces are sucked out of the carrying plate 4 by vacuuming the negative pressure; according to needs, the upper end of the suction tube 7 is set as a pointed head to ensure that the go pieces after being sucked down will not be supported at the upper end of the suction tube 7, but will fall sideways into the collecting tank 9.

[0023] The controller is respectively connected with the drive mechanism, thickness detector and control valve 8 by signal. When it is implemented, the chain circle 1 is started for transmission, and the chess pieces are pressed down one by one at the position of the active sprocket 2 and installed on the passing carrier plate 4. The carrier plate 4 fixed by the chain unit 101 and the elastic clamping strip 5 are used to clamp the go pieces, so that the go pieces can be circulated and transmitted by the chain circle 1. In the process of transmission, the thickness is detected by the thickness detector, and the detection data is fed back to the controller in order, so that the moving position of the chess piece and the specification data are matched in real time. When the go piece flips to the lower part of the chain circle 1, the controller can control the suction mechanism to suck and discharge the go pieces corresponding to the same specification thickness range, and complete the sorting work of different thicknesses.

[0024] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
