[0025] Referring to Figure 1 , Figure 2 A flexible self-locking positioning device of a trolley, comprising a trolley body 5 and a connecting part 6 arranged on a chip mounter, the connecting part 6 and the trolley body 5 are movably connected through a sliding assembly 2, a middle buckling assembly 1 and an end buckling assembly 3, the trolley body 5 slides on the connecting part 6 of the chip mounter through the sliding assembly 2 and is buckled through the middle buckling assembly 1 and the end buckling assembly 3. The connecting part 6 is provided with two, and the two connecting parts 6 are movably connected with the trolley body 5 through the sliding assembly 2 and the middle buckling assembly 1 at both ends of the trolley body 5, and the end buckling assembly 3 is arranged at the end of the connecting part 6 connected with the trolley body 5. The trolley body 5 provided with the connecting part 6 is detachably connected with the chip mounter, increasing the versatility of the trolley and facilitating transportation. When installing the trolley body 5 and the chip mounter, the trolley can be pushed in a distance first, and after the connection between the sliding assemblies 2 is realized, the middle buckling assembly 1 is started, which can drive the trolley to move a small distance, further position the trolley, and then automatically lock after positioning, realizing the stable installation between the trolley body 5 and the chip mounter.

[0026] Referring to Figure 3 , Figure 4, Specifically, the sliding assembly 2 comprises a middle axle 21, a middle clamping groove 22 and a sliding rail 23. The middle axle 21 is adjustably arranged at the side of the trolley body 5, and the middle clamping groove 22 and the sliding rail 23 are matched with the middle axle 21 on the connecting part 6 of the chip mounter. The middle axle 21 is provided with two, and the two middle axles 21 are horizontally arranged at the side of the trolley body 5. The middle clamping groove 22 is arranged at the end of the sliding rail 23, and the two middle axles 21 are slidingly arranged on the sliding rail 23, and the middle axle 21 arranged at the front end is clamped with the middle clamping groove 22. The middle axle 21 is arranged on the trolley body 5, and the outer periphery is wrapped with a rotatable rotating wheel, and the sliding rail 23 is arranged on the side rail of the trolley body 5. The rotating wheel can roll on the horizontal bottom edge of the rail. One of the two middle axles 21 is matched with the middle clamping groove 22 to form a clamping, and the other is arranged at the other end of the sliding rail 23, and the corresponding position of the sliding rail 23 is provided with an arc-shaped recess. When the tail middle axle 21 falls into the recess, it can give the human body weight a disengaging feedback, so that the person pushing the trolley can feel that the middle axle 21 is clamped with the middle clamping groove 22, so as to avoid the damage to the middle clamping groove 22 caused by the inability to timely collect force when exerting force again. These structures can not only position the trolley body 5 within a certain range, but also facilitate the movement of the trolley, facilitate the exertion of force on the trolley body 5, and further push the trolley body 5 into the installation position.

[0027] Refer to 2, Figure 7 Because the manual pushing is adopted when the interactive rail on the trolley body 5 is pushed into the position matched with the middle axle 21, and the error is large during the pushing process, misalignment is easy to occur, which causes damage to the trolley body 5 and the connecting structure. Therefore, the middle axle 21 is connected with the trolley body 5 through the adjustable structure 4, and the adjustable structure 4 is arranged on the side of the trolley body 5 opposite to the direction of the middle axle 21. The adjustable structure 4 comprises a movable mounting block 41 and a connecting screw 42. The movable mounting block 41 is provided with a movable mounting hole 43, the connecting screw 42 passes through the movable mounting hole 43 and is connected with the middle axle 21, and the bottom of the movable mounting hole 43 is further provided with a fixed mounting block 44. The fixed mounting block 44 is provided with an adjusting screw 45, and the adjusting screw 45 adjusts the movable mounting block 41 at the bottom of the movable mounting block 41. When the height of the trolley body 5 is low, the adjusting screw 45 can be twisted, the adjusting screw 45 arranged at the bottom of the movable mounting block 41 moves downward, so that the force for lifting the movable mounting block 41 is reduced, the movable mounting block 41 moves downward, and the middle axle 21 moves downward and is matched with the lower sliding rail 23. Conversely, twist the adjusting screw 45 to adjust the middle axle 21 upward. The cooperation between the adjustable middle axle 21 and the interactive rail is more flexible, the applicability to trolleys of different heights is increased, and the stability and safety of the trolley body during the pushing process are increased.

[0028] The middle buckling assembly 1 comprises a driving cylinder 12, a connecting rod assembly 11, a movable hook 13 and a movable buckle 14, the connecting rod assembly 11 is used for connecting the driving cylinder 12 and the movable hook 13, the movable hook 13 is movably connected with the movable buckle 14, the driving cylinder 12 and the connecting rod assembly 11 are arranged in the inside of the connecting part 6, the side of the connecting part 6 is provided with a hook groove, the movable hook 13 is rotatably arranged in the hook groove. The movable buckle 14 is arranged on the trolley body 5 through a buckle block, the buckle block is provided with a buckle groove, the movable buckle 14 is rotatably arranged in the buckle groove, the end of the movable hook 13 is provided with a hook groove, the movable hook 13 is engaged with the movable buckle 13 through the hook groove. The movable hook 13 driven by the driving cylinder 12 and the connecting rod assembly 11 can change the linear motion provided by the driving cylinder 12 into the progressive motion process of linear plus rotation, when the movable hook 13 is connected with the movable buckle 14, the motion track of linear plus rotation is convenient for the movable buckle 14 to contact with the movable hook 13 to form the stable buckling, the too deep hook groove of the hook will not affect the contact between the movable hook 13 and the movable buckle 14, and the stability of the middle buckling assembly 1 during buckling is increased.

[0029] Referring to Figure 5 , Figure 6The connecting rod assembly 11 comprises a first connecting rod 111 integrated with the movable hook 13, the first connecting rod 111 is rotatably arranged through a first pin shaft 115, the first connecting rod 111 is arranged in a "V" shape with the movable hook 13, the first pin shaft 115 is arranged at the turning position of the first connecting rod 111 and the movable hook 13, the end of the first connecting rod 111 is provided with a sliding way, the air rod of the driving cylinder 12 is slidably arranged in the sliding way at the end of the first connecting rod 111, and the air rod is movably provided with a second connecting rod 112 at the connecting position of the air rod and the first connecting rod 111, the other end of the second connecting rod 112 is rotatably arranged through a second pin shaft 116, the first pin shaft 115 and the second pin shaft 116 are further provided with a third connecting rod 113 and a connecting block 114, the connecting block 114 is fixedly arranged at the top of the first pin shaft 115 and the second pin shaft 116, and the bottom of the connecting block 114 is further provided with a third pin shaft 117, the three pin shafts are arranged in a triangle shape at the bottom of the connecting block 114. When the air rod of the driving cylinder 12 is extended, the connecting part of the first connecting rod 111 and the movable hook 13 is pushed, and since the air rod of the driving cylinder 12 is slidably connected with the first pin shaft 115, the vertical force is cancelled when the movable hook is pushed, and the air rod of the cylinder pulls the movable hook 13 to rotate clockwise. However, since the second pin shaft 116 and the third pin shaft 117 are further connected to the movable hook 13 and the first connecting rod 111, the movement distance of the first connecting rod 111 is limited, so that the movement is converted into rotation, and the hook groove of the movable hook 13 is sleeved with the movable buckle 14 after rotating around the movable buckle 14, thereby completing the buckling of the two. This connecting rod type driving mode not only saves the installation space occupied by the motor and other driving devices, but also increases the diversity and stability of the movement process through pure mechanical connection driving, thereby increasing the service life of the equipment.

[0030] When the connecting part 6 of the chip mounter and the trolley body 5 are positioned and installed, in order to prevent the trolley body 5 from moving forward on the chip mounter beyond the relative limit range of the installation position, the end buckling assembly 3 comprises an end hook 31 and an end buckle 32, the end buckle 32 is arranged at the end of the connecting part 6, the end hook 31 is arranged at the end of the trolley body 5 and vertically arranged at the end of the trolley, the length of the hook groove edge of the end hook 31 is greater than the length of the end buckle 32, and the end buckle 32 is movably connected with the end hook 31 through the elastic hook groove edge of the end hook 31. After the middle buckling assembly 1 is buckled, the end hook and the end buckle 32 arranged at the end are in contact, and when the end hook 31 is subjected to a greater impact force, due to the elasticity of the edge of the end hook 31, the end hook 31 and the end buckle 32 are buckled to limit the trolley body 5, preventing the trolley body 5 from moving forward beyond the connection position between the trolley and the chip mounter, thereby further increasing the stability and safety of the trolley installation process.

[0031] The above is a specific description of the preferred embodiment of the application, but the application is not limited to the described embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the application, and these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
