In this embodiment, the ejector pin holder elastic member 23 is a compression spring, and when the ejector pin 1 works, the ejector pin holder elastic member 23 abuts against the ejector pin holder 221, so that the clamping member 222 extends into the mounting cavity 20 to clamp the ejector pin 1, and only when the ejector pin 1 is replaced, additional power needs to be applied to the ejector pin holder 221, thereby saving power resources and having a simple structure.

One of the key points of the quick-replacing device 1000 of the present application is that the clamping piece 222 is extended into or retracted from the mounting cavity 20 through the thimble clamping seat 221 to clamp or unclamp the top needle cylinder 1, thereby realizing quick replacement of the top needle cylinder 1. In order to facilitate the clamping piece 222 to clamp the top needle cylinder 1, as shown in fig. 3, in this embodiment, the outside of the thimble cylinder 11 is provided with a clamping groove 114, and when the thimble cylinder clamp 22 clamps the top needle cylinder 1, the clamping piece 222 stretches into the clamping groove 114, so that the top needle cylinder 1 can be stably clamped on the one hand, and the top needle cylinder 1 can be assisted to be installed in place on the other hand. Further, in the embodiment, the locking element 222 is a steel ball, the cross section of the locking groove 114 is arc-shaped, so that the locking element 222 can be adaptively locked into the locking groove 114 only by installing the top needle cylinder 1 in place, and the operation is convenient. In this embodiment, the contact surface between the ejector pin holder 221 and the clamping piece 222 is an inclined surface, so that all the clamping pieces 222 can be adjusted by moving the ejector pin holder 221 along the same direction, the moving direction of the ejector pin holder 221 can be the same as the moving direction of the movable seat 1223, and the moving direction of the member requiring additional driving force in the whole device is the same, so that the structure is simple, the operation is stable, and the space is saved.

The cylinder is connected with the pushing piece 24, the cylinder pushes the pushing piece 24 to move upwards, the movable seat 1223 is stressed to drive the thimble installation reference table 1222, the thimble installation disc 1221 and the thimble 121 to move upwards, the thimble 121 is ejected out of the thimble cover 113 by the required length, and meanwhile, the vacuum connector 81 for connecting the installation cavity 20 to the vacuum is opened to the vacuum, so that the thimble 121 adsorbs the target piece. When the thimble 121 needs to be retracted after the task is completed, the air cylinder drives the pushing piece 24 to move downwards, and the movable seat 1223 drives the installation reference table 1222, the thimble installation disc 1221 and the thimble 121 to descend under the action of the movable seat elastic piece 13 until reset, so that the working procedure is completed.

And (3) quick-change process: when the ejector cylinder 1 needs to be quickly replaced, the pneumatic connector 82 for driving the ejector pin clamping seat 221 is ventilated, the ejector pin clamping seat 221 is pushed by aerodynamic force to move downwards, the ejector pin clamping seat elastic piece 23 is compressed, the clamping seat elastic piece 23 does not abut against the steel balls (clamping piece 222), so that the steel balls are loosened and separated from the clamping groove 114, the ejector cylinder 1 is loosened, the ejector cylinder 1 can be pulled out of the mounting cavity 20, after the required ejector cylinder 1 is replaced, the pneumatic connector 82 for ventilating and pneumatically driving the ejector pin clamping seat 221 is disconnected, the ejector pin clamping seat 221 moves upwards under the action of the ejector pin clamping seat elastic piece 23 to abut against the steel balls, and the steel balls extend into the clamping groove 114 to clamp the ejector cylinder 1, so that a quick replacement process is completed.

According to the ejector cylinder quick-change device 1000 in the above embodiment, through the action of the ejector cylinder clamp 22, when the ejector cylinder 1 needs to be replaced, the ejector cylinder 1 can be taken out only by controlling the position of the ejector pin clamp seat 221 so that the clamp piece 222 is retracted out of the mounting cavity 20 to loosen the ejector cylinder body 11, and after the replaced ejector cylinder 1 is placed into the mounting cavity 20 in place, the ejector pin clamp seat 221 can be controlled to reset so that the clamp piece 222 extends into the mounting cavity 20 to clamp the ejector cylinder body 11, thereby fixing the ejector cylinder 1, and the ejector cylinder quick-change device is easy to assemble and disassemble and convenient to replace and has low cost. Meanwhile, the elastic piece is adopted to realize the resetting of part of the components, compared with the existing thimble barrel replacement device, the driving force is saved, the saved air path can be used for the vacuum ventilation of the thimble 121, and the thimble barrel replacement device is simple in structure, convenient to operate and time-saving. And most movable components in the whole device have the same moving direction, and the device has the advantages of simple structure, stable operation and space saving.

The foregoing description of the utility model has been presented for purposes of illustration and description, and is not intended to be limiting. Several simple deductions, modifications or substitutions may also be made by a person skilled in the art to which the utility model pertains, based on the idea of the utility model.
