[0021] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0022] In the prior art, the code disc is generally adsorbed by a suction cup, and then the inner and outer edges of the code disc are polished. Although this adsorption effect is relatively good, since the size of the suction hole is generally fixed, for a code disc with a narrow edge, the suction hole size is too large, and the code disc may not be able to cover the suction hole, making it difficult to ensure the stability of adsorption. For a code disc with a wide edge, the suction hole size is small, and it is also difficult to ensure the stability of adsorption.

[0023] It should be understood that the narrow side and wide side of the code disk are defined based on the difference between the inner diameter and the outer diameter of the code disk. That is, if the difference between the inner diameter and the outer diameter is too small, it means that the code disk has a narrow side. If the difference between the inner diameter and the outer diameter is large, the code disk has a wide side.

[0024] To solve the above technical problems, please refer to Figure 1 The present application proposes a glass code disk fixing chuck for cooperating with a cylinder, comprising a seat body 10 and a plurality of clamping parts 20.

[0025] The base 10 is connected to the pneumatic cylinder. It's important to understand that the entire pneumatic clamping device primarily consists of a pneumatic chuck, a cylinder, a valve, and a control system. The pneumatic chuck is the primary component that performs the clamping action, while the cylinder provides the power source, the valve controls the cylinder's movement, and the control system provides overall coordination and control.

[0026] Air source input: The air source is input into the cylinder through the pipeline to provide power for the movement of the cylinder.

[0027] Cylinder piston movement: When the air valve is opened, air enters the cylinder, pushing the piston forward or backward. The direction of the piston's movement depends on the control of the air valve.

[0028] Chuck body movement: The movement of the piston causes the pneumatic chuck to clamp or release. Specifically, when the cylinder piston moves forward, it pushes the pneumatic chuck's clamping jaws toward the workpiece, achieving a clamping action. When the cylinder piston moves backward, the pneumatic chuck in the chuck body opens, releasing the workpiece.

[0029] The base 10 can be mounted to the cylinder via bolts, threads, or other means. This is prior art and will not be explained in detail here. The primary improvement in this application lies in the structure of the pneumatic chuck itself. Specifically, the pneumatic chuck (also known as a "fixed chuck") includes a plurality of clamping portions 20 connected to one side of the base 10 along the central axis of the base 10. The plurality of clamping portions 20 are spaced apart around the central axis and enclose a clamping groove 10a, with a notch 10b defined in the center. Under the action of the cylinder, the plurality of clamping portions 20 can be moved toward or away from each other relative to the central axis.

[0030] During the specific implementation process, the glass code disc is placed in the clamping groove 10a by means of a robot or the like, and then under the action of the cylinder, multiple clamping parts 20 approach each other to clamp the outer edge of the code disc. It can be understood that the depth of the clamping groove 10a should be sufficient. When the code disc is placed in the clamping groove 10a, at least part of it extends out of the clamping groove 10a, that is, it is equivalent to the code disc being semi-embedded in the clamping groove 10a, so that the grinding or chamfering equipment can process the outer edge of the code disc, and the notch 10b can be facing the middle of the code disc, so that the grinding or chamfering equipment can extend into the middle of the code disc to process the inner edge of the code disc.

[0031] It should be understood that in the present application, since the outer edge of the code disk is clamped by the clamping portion 20 rather than being clamped or adsorbed by the surface of the code disk, it is not affected by the wide side or narrow side of the code disk. Within a certain range, it can provide a good clamping effect for both wide and narrow side code disks.

[0032] In the embodiment of the present application, the main focus is on an annular code disk. In order to improve the clamping effect, the portion of the clamping portion 20 that contacts the outer edge of the code disk is an arc surface. In this way, the contact area with the code disk can be increased, thereby improving the clamping effect.

[0033] After processing one side of the code disc, the code disc can be removed, and then the processed side is placed in the clamping groove 10a, and then the other side of the code disc is processed.

[0034] See also Figure 1 It should be understood that since there will be patterns on the surface of the code disk, in order to avoid scratches between the patterns and the bottom of the clamping groove 10a, multiple groups of base supports 30 are provided in this application. The multiple groups of base supports 30 are correspondingly arranged on the multiple clamping parts 20, and the base supports 30 are installed on the bottom of the clamping groove 10a.

[0035] The base 30 not only prevents scratches but also enhances the stability of the code disc during the clamping process. They provide additional support points for the code disc, making it more stable during processing and less likely to move or deform. The position of the base 30 is staggered with the pattern, meaning that the base 30 can support the code disc while not contacting the pattern on the code disc, thereby improving the processing yield of the code disc.

[0036] The base 30 is integrally connected to the clamping portion 20. This means the clamping portion 20, base 30, and base 10 can be integrally molded. All are injection molded using PEEK (Poly-Ether-Ether-Ketone), ensuring overall stability. This one-piece structure reduces the number of parts and assembly steps, thereby simplifying the production process. This not only improves production efficiency but also reduces production costs. Furthermore, using a shared mold for injection molding further simplifies the production process, ensuring product consistency and reliability.

[0037] The use of PEEK injection molding can ensure that the clamping portion 20, the base 30 and the seat body 10 have sufficient strength and rigidity to withstand various forces and temperature fluctuations during the processing.

[0038] In some other embodiments, see Figure 2The base 30 can be detachably connected to the clamping portion 20. When the base 30 is worn or contaminated, it can be easily removed for cleaning or replacement without disassembling the entire fixing chuck. This greatly simplifies maintenance and extends the service life of the fixing chuck.

[0039] In addition, for code discs of different thicknesses, the clamping portion 20 can be enabled to stably clamp the edge of the glass code disc by replacing the base bracket 30 with different lengths. For example, for code discs with thicker thicknesses, the length of the base bracket 30 can be replaced so that more of the glass code disc is located in the clamping groove 10a, thereby enabling the clamping portion 20 to stably clamp the glass code disc.

[0040] Specifically, the base support 30 is threadedly connected to the clamping part 20. In one embodiment, a threaded groove can be provided on the base support 30, and a screw can be provided on the clamping part 20 to achieve the detachable function through threaded connection. Alternatively, an external thread can be provided on the base support 30, and a threaded groove can be provided on the clamping part 20, and the detachable function can be achieved through threaded connection between the base support 30 and the threaded groove.

[0041] When external threads are provided on the base 30, there is also a portion of the surface where no threads are provided. For bases 30 of different lengths, the area where no threads are provided occupies different areas along the length of the base 30, so that bases 30 of different lengths can be replaced for code discs of different thicknesses.

[0042] It can also be understood that a plurality of threaded grooves are provided on the clamping portion 20, and the user can install the base 30 in a targeted manner according to the pattern areas of different code disks, so that the base 30 is staggered with the pattern area, thereby further increasing the applicability of the fixing chuck in the embodiment of the present application.

[0043] Of course, in some other embodiments, the user can also open a positioning groove in the clamping portion 20, and set a spring clip inside the positioning groove. The base support 30 can be extended into the positioning groove, and the side wall of the base support 30 is clamped by the spring clip, thereby limiting and fixing the base support 30.

[0044] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the drawings. This is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
