The present invention will be described in detail below with reference to the accompanying drawings. The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but not to be construed as a limitation of the present invention. Orientation terms such as left, middle, right, upper and lower in the examples of the present invention are only relative concepts to each other or refer to the normal use state of the product, and should not be regarded as limiting.
 A pull-type manipulator loading and unloading structure, such as figure 1 and image 3 As shown, it includes a manipulator and an inclined first feeding channel 1, the manipulator is arranged on the first feeding channel 1 and moves back and forth, and the manipulator is provided with a second feeding channel 2, The second feeding channel 2 is arranged in parallel with the first feeding channel 1 and communicates with each other. A material blocking mechanism is provided on the first feeding channel 1 near the unloading side of the manipulator. The mechanism is linked with the manipulator. When the manipulator drives the second feeding passage 2 to move to the first feeding passage 1 and communicates with each other, the actuator provided by the blocking mechanism cuts off the first feeding passage 1; When the manipulator drives the second feeding channel 2 to move and is staggered from the first feeding channel 1, the actuator releases the state of cutting off the first feeding channel 1, and the feeding side of the manipulator stops at the On the first material passing channel 1 ; a processing port 421 communicating with the first material passing channel 1 is opened on the manipulator.
 Among them, combined figure 2 , Figure 4 and Figure 5 As shown, the manipulator comprises a strip-shaped plate, the strip-shaped plate is arranged on the first material-passing channel 1 and is perpendicular to each other, and the second material-passing channel 2 is arranged on the strip-shaped plate; One end of the strip-shaped plate is linked with the telescopic mechanism 43 to move back and forth along its long direction. The cross section of the first feeding channel 1 is a rectangular structure, the bottom wall and the top wall of the first feeding channel 1 are used to contact the outer circumferential surface of the ferrule, and the side wall of the first feeding channel 1 It is used for contacting with the end face of the ferrule; the strip plate includes a strip baffle 41 and a panel 42 , and the side wall of the first feeding channel 1 is provided with a gap corresponding to the position of the panel 42 , and the panel 42 Located in the gap, one side of the panel 42 is the fixing part 402, the other side of the panel 42 is the blocking part 401, and the strip-shaped baffle 41 is fixedly connected to the fixing part and penetrates through it. The top wall and the low wall of the first feeding channel 1, the second feeding channel 2 are located on the strip baffle 41, and the top wall and the low wall of the second feeding channel 2 are both located on the On the strip baffle 41, one side wall of the second feeding channel 2 is located on the panel 42, the other side of the second feeding channel 2 is open, and the processing port 421 is located on the panel 42. The fixing portion 402 corresponds to the position of the second material feeding channel 2, and a material blocking block 422 is provided on the unloading side of the material blocking portion 401 and corresponding to the position of the second feeding channel 2. The position corresponding to the material blocking block 422 on the top wall or the lower wall of the first feeding channel 1 is provided with a pass-through groove 11 , and the material blocking block 422 is the material blocking mechanism. The bit-through groove 11 is moved out of the first feeding channel 1 .
 like figure 1 and image 3As shown, the upper end of the first feeding channel 1 is connected with a vertically arranged third feeding channel 3, which includes a base plate 5 and a cover plate 51 fixedly attached to the base plate 5. On the base plate 5 The upper position between the base plate 5 and the cover plate 51 starts with a vertical groove and an oblique groove, and the vertical groove and the cover plate 51 form the third feeding channel 3. The groove and the cover plate 51 constitute the first material passing channel 1 . The telescopic mechanism 43 is a double-rod telescopic cylinder, and the synchronous telescopic double rods provided in the double-rod telescopic cylinder are fixedly connected to the strip baffle 41 .
 The working principle of the invention: the bearing ring rolls from the third feeding channel into the first feeding channel and into the second feeding channel on the manipulator, and the telescopic mechanism drives the strip baffle and the bearing ring in it Movement, move the second bearing ring to the grinding position, grinding starts, and at the same time the first bearing ring completes blanking, grinding ends, the drive mechanism returns, and the manipulator drives the second bearing ring to return, Move the second bearing ring to the upper and lower material level, the grinding is finished, at the same time, the second bearing ring enters the lower half of the first material passage, and the third bearing ring enters the second passage and passes through. The conversion is complete and the first loop ends.
 The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have Various changes and modifications fall within the scope of the claimed invention. The claimed scope of the present invention is defined by the appended claims and their equivalents.
