[0023] like Figures 1 to 8 As shown, in this embodiment, the utility model includes a placement seat 1, a limit push assembly 2 and several side push assemblies 3, and mounting grooves 11 for fixing and connecting several side push assemblies 3 are formed on both sides of the placement seat 1, three slide grooves 12 are formed in the middle of the placement seat 1, and a connecting plate 13 is provided on the lower surface of the placement seat 1. The limit push assembly 2 includes a push drive device 21 arranged on the connecting plate 13, a lifting block 22 arranged at the movable end of the push drive device 21, and a push block 23 for squeezing and limiting the shell body and corresponding to the corresponding slide groove 12. The lifting block 22 is formed with three connecting ears 24, and each connecting ear 24 is connected to the corresponding push block 23 by a connecting rod 25. The push drive device 21 is a telescopic cylinder, which is received in the placement seat 1 The three slides 12 are arranged at equal intervals, and there is an angle of 120 degrees between two adjacent slides 12. Multiple groups of side push assemblies 3 arranged on the side are adopted. When the product is placed in the side push assembly 3, the side push drive device 32 pushes the push block 33 to approach and fits tightly to the shell through the buffer pad 35, forming a pre-positioning in the X-axis and Y-axis directions of the shell. After the pre-positioning is completed, the push drive device 21 is ejected, and the lifting block 22 drives the push block 23 in the slide 12 to move through the connecting rod 25. The pad 28 is squeezed and deformed with the inner wall of the shell, so that the shell is positioned on the placement seat 1 through friction. After positioning is completed, each group of side push drive devices 32 retracts, and the buffer pad 35 disengages and moves away from the outer surface of the shell, which is convenient for the appearance inspection mechanism to perform visual inspection on the outer surface of the shell, thereby improving the inspection accuracy. The overall structure is simple and convenient for daily maintenance by the staff.
[0024] In this embodiment, the pushing block 23 includes a sliding plate 231 that slides with the slide groove 12, a limit block 232 arranged on the upper surface of the sliding plate 231, a lifting adjustment plate 26 for adjusting the pushing height arranged on one side of the sliding plate 231, and a lifting adjustment plate 27 that slides with the lifting adjustment plate 26. The lower surface of the sliding plate 231 is formed with a rotating block 233 that is rotatably connected to the connecting rod 25. The limit block 232 and the sliding plate 231 cooperate to form a limit space that guides the slide groove 12. An adjusting screw 234 that threadably cooperates with the lifting adjustment plate 26 is provided between the limit block 232 and the lifting adjustment plate 26. A spring for floating support is provided between the lifting adjustment plate 26 and the lifting adjustment plate 27. The elastic member 235 is a compression spring. The inner wall of the shell is usually not a uniform circular structure. The elastic member 235 is used in conjunction with the slidable lifting and adjusting plate 27 structure. When the floating pad 28 contacts the inner wall of the shell, the elastic member 235 provides a thrust to make the pad 28 close to the inner wall of the shell, ensuring the effect of extrusion friction, while preventing the floating push block 33 from forming a rigid contact with the inner wall of the shell, causing damage to the inner wall of the shell.
[0025] In this embodiment, a block 261 is formed at the lower portion of the lifting adjustment plate 26, and a protruding plate 262 is formed in the middle portion of the lifting adjustment plate 26, which is threadedly engaged with the adjusting screw 234. A sleeve 263 is formed on the upper portion of the lifting adjustment plate 26, which is guided and engaged with the lifting adjustment plate 27. A guide column 264 is provided in the sleeve 263, which is guided and engaged with the elastic member 235. A guide groove 265 is formed on the side wall of the sleeve 263. A protrusion 271 is formed on the lifting adjustment plate 27 to slide and engage with the guide groove 265. The block 261 is limited and engaged with the sliding plate 231 to limit the maximum lifting position of the lifting adjustment plate 26. The protruding plate 262 is formed with a screw hole threadedly engaged with the adjusting screw 234. The protrusion 271 and the guide groove 265 cooperate to effectively prevent the lifting adjustment plate 27 from encountering a side thrust when pushing the inner wall of the shell, thereby causing the floating push block 33 to rotate.
[0026] In this embodiment, a second end of the sliding plate 231 is formed with an anti-collision block 236 that pushes and limits the sliding groove 12. The anti-collision block 236 is a rubber structure and is used to prevent the lifting adjustment plate 26 from colliding with the sliding groove 12.
[0027] In this embodiment, the side thrust assembly 3 includes a fixed seat 31 fixedly connected to the mounting groove 11, a side thrust driving device 32 arranged at the lower end of the fixed seat 31, and a side pressure pushing block 33 rotatably connected to the upper part of the fixed seat 31 for transmitting the side thrust force. The movable end of the side thrust driving device 32 is provided with a rotating seat 34 rotatably connected to the first end of the side pressure pushing block 33, and the other end of the side pressure pushing block 33 is formed with a buffer pad 35 in contact with the shell. The side thrust driving device 32 is a telescopic cylinder, and the middle part of the side pressure pushing block 33 is rotatably connected to the fixed seat 31, and the pushed end is connected to the movable end of the side thrust driving device 32. When the side thrust driving device 32 is extended, the buffer pad 35 is pushed close to the outer surface of the shell by the lever principle.
[0028] In this embodiment, the side pressure push block 33 is in a “Z” shape.
[0029] In this embodiment, a through hole rotatably connected to the fixing seat 31 is formed in the middle of the side pressure push block 33 , and a transmission groove rotatably connected to the rotating seat 34 is formed at the first end of the push block 33 .
[0030] In this embodiment, waist-shaped grooves are formed at both ends of the connecting rod 25 .
[0031] The working principle of this utility model:
[0032] Before use, the staff adjusts the screw 234 by turning the knob according to the height of the inner wall of the shell to make the pad 28 equal to the middle of the inner wall of the shell;
[0033] After being placed in the shell, the multiple groups of side push drive devices 32 located on both sides push the push block 33 to approach and fit tightly to the shell through the buffer pad 35, forming a pre-positioning in the X-axis and Y-axis directions of the shell. After the pre-positioning is completed, the push drive device 21 is ejected, and the lifting block 22 drives the push block 23 in the slide groove 12 to move through the connecting rod 25. The pad 28 is squeezed and deformed with the inner wall of the shell, thereby positioning the shell on the placement seat 1 through friction. After positioning is completed, each group of side push drive devices 32 retracts, so that the buffer pad 35 is detached and away from the outer surface of the shell. The appearance inspection device can perform a complete visual inspection of the outer surface of the shell.
[0034] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
