[0025] The technical solution of the utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-4 As shown, a special gripper for a loading and unloading robot includes a support frame 1 and a flange 2. The support frame 1 includes a support platform 10, a support plate 11 and a mounting plate 12. The support platform 10 is a horizontal U-shaped thin plate. The length of the support platform is 850 mm, the width is 315 mm, and the thickness is 12 mm. One end is a connecting end, and the other end is a grasping end. The mounting plate 12 is vertically welded below the connecting end of the support platform 10. The mounting plate 12 is a rectangular thin plate. An arc plate is added to the middle of the bottom edge of the mounting plate. The mounting plate 12 is provided with connecting holes 13. The shape of the multiple connecting holes 13 is arc-shaped. The connecting holes 13 correspond to the holes at the lower end of the flange 2. The mounting plate 12 is connected to the flange 2 by bolts 3. The upper end of the flange 2 is connected to the robot by bolts 3. The support platform 10 Support plates 11 are vertically welded below both sides of the U-shaped arm. The support plates 11 are irregular in shape and are an integrated structure. They are composed of two different right-angled trapezoidal plates and a rectangular plate. The support plate 11 near the connecting end is composed of a rectangular plate and a right-angled trapezoidal plate 1. The bottom side of the right-angled trapezoidal plate 1 is the same length as the long side of the rectangular plate. The long side of the rectangular plate is welded to the support platform 10, and the other long side of the rectangular plate is integrally formed with the bottom side of the right-angled trapezoidal plate 1. The support plate 11 near the grasping end is composed of a right-angled trapezoidal plate 2. The bottom side of the right-angled trapezoidal plate 2 is as long as the width of the rectangular plate. Similarly, the right-angled side of the second right-angled trapezoidal plate is welded to the support platform 10, and the bottom edge is integrally formed with the wide side of the rectangular plate. The bottom of the support plate 11 forms a "V"-shaped structure, and the other wide side of the rectangular plate is welded to the mounting plate 12; by welding the support platform and the support plate, the overall structural stability is enhanced to prevent the gripper from deforming under load and high temperature conditions; the bottom of the support plate adopts a "V"-shaped structure to prevent the material frame from moving at will, and the heat conduction of the sample in the material frame from causing motor failure, while also preventing the material frame from swinging back and forth during operation and causing deviation; special grippers replace manual loading and unloading to eliminate safety hazards.

[0027] The support frame 1, flange 2 and bolt 3 are all made of stainless steel 0Cr18Ni9; the gripper is close to the robot motor, and stainless steel 0Cr18Ni9 has poor thermal conductivity, so as to avoid motor failure caused by heat conduction between the material frame and the sample.

[0028] The loading and unloading time of the special gripper is generally 15 to 25 seconds. In actual application, the gripper fully meets the loading and unloading requirements of the robot. It is used for a short time and at high temperature without any deformation and has little effect on the temperature of the robot. The application effect is good.
