Therefore, the features limited by “first” and “second” can explicitly or implicitly include at least one of the features.

[0031] Please refer to Figures 1-14 The base and the loading and unloading clamping jig according to the embodiments of the present application.

[0032] The loading and unloading clamping jig includes a body and two clamping plates. The clamping plates are matched in size and shape with the glass panel product to be polished. The body is square, and the body is composed of a pressing plate, a fixed plate and two fixed side plates respectively arranged at the front, back, left and right. The body is provided with adjustable side plates on the left and right sides, and the bottom of the body is provided with an adjustable bottom plate corresponding to the position that can be adjusted up and down. The user can adjust the adjustable side plates and the adjustable bottom plate, so that the loading and unloading clamping jig of the present application can be matched with glass panel products of different specifications.

[0033] The middle part of the pressing plate and the fixed plate of the body is provided with a positioning groove, which is used for quick positioning during feeding. The pressing plate is provided with a quick clamp. Preferably, the quick clamp has two, which are arranged on the left and right sides of the pressing plate. The quick clamp is used to press against the clamping plate, so that the two clamping plates clamp a stack of glass panel products, facilitating the simultaneous feeding and discharging of the stack of glass panel products. The quick clamp adopts a push-pull compression type clamp.

[0034] A motor is arranged on the base, and the output shaft of the motor is vertically upward. The motor drives the glass panel product to rotate. A cylinder is arranged above the motor, and the piston rod of the cylinder is vertically downward. The piston rod is provided with a shaft sleeve, and a locating shaft one is vertically arranged in the shaft sleeve through a bearing. The locating shaft one is coaxial with the output shaft of the motor, and the bottom end of the locating shaft one and the top end of the output shaft are both provided with a positioning block matched with the positioning groove. The cylinder drives the shaft sleeve, the bearing and the locating shaft one to move downward to compress the glass panel product.

[0035] As an embodiment, a guide sleeve is further arranged on the base and surrounds the shaft sleeve, which prevents the shaft sleeve from moving up and down.

[0036] As an embodiment, a polishing wheel mechanism is arranged above the base corresponding to the two sides of the motor. The polishing wheel mechanism can adopt an existing polishing wheel mechanism to polish the glass panel product in the middle.

[0038] As an embodiment, a waist-round through hole is symmetrically arranged on the pressing plate and the fixed plate, which is consistent with the adjustable direction of the adjustable side plate and the adjustable bottom plate. An adjusting screw is arranged on the adjustable side plate and the adjustable bottom plate and passes through the through hole, so that the position is adjustable through the adjusting screw.

[0039] As an embodiment, a scale mark corresponding to the through hole is arranged on the pressing plate and the fixed plate. The scale mark facilitates the user to accurately adjust the position of the adjustable side plate and the adjustable bottom plate.

[0040] As an embodiment, a positioning hole is arranged in the middle of the clamping plate, and the clamping fixture further comprises a positioning plate and a locating shaft two matched with the positioning hole. The bottom of the positioning plate is provided with a positioning part matched with the positioning groove in front of and behind the body. The middle part of the positioning part is provided with a positioning slot hole through which the locating shaft two passes. When the clamping plate is positioned, the two clamping plates are placed on the body, the positioning plate is placed on the body, the positioning part is embedded in the positioning groove, and then the locating shaft two passes through the positioning part on one side, the two clamping plates and the positioning part on the other side. In this way, the two clamping plates can be quickly centered, and then the adjustable side plate and the adjustable bottom plate are adjusted to tightly clamp the clamping plate, and finally the adjustable side plate and the adjustable bottom plate are fixed.

[0041] The working principle of the present application is as follows: when loading, two clamping plates are placed into the body at the front and rear ends, and then a plurality of glass panel products are stacked between the two clamping plates; after stacking, the quick clamps are pressed to clamp the glass panel products; then the loading and unloading clamping jig is placed between the alignment shaft I and the output shaft of the peripheral polishing machine, the body is vertically placed on the output shaft, and the body is embedded in position through the positioning groove and the positioning block, the positioning block on the alignment shaft I is embedded into the positioning groove at the front end of the body, and then the glass panel products between the clamping plates are pressed tightly, so that the loading of the plurality of glass panel products is realized; finally, the quick clamps are loosened, and the body is removed; when unloading after polishing, the body is sleeved on the stack of glass panel products that have been polished through the alignment of the positioning groove, the quick clamps are pressed to fix the glass panel products that have been polished, and then the body is removed.

[0042] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
