[0027] See also Figures 1 to 6 , the figure discloses a casing removal jig, including a mounting plate 1, a connecting device 2 connecting the mounting plate and a contour structure 3, wherein:

[0028] The mounting plate is provided with a mounting seat 11, an opening 12, a through hole 13 and a stepped hole 14. In this embodiment, four circular through holes 13 are provided at the four corners of the mounting plate, two openings are located on opposite sides of the mounting plate and between the two through holes, and two stepped holes are located on the other opposite sides of the mounting plate and between the two through holes. The aperture of the stepped hole is larger than the aperture of the opening. The mounting seat is located in the middle of the mounting plate and is provided with a notch (not marked) of the same position and number as the middle of the mounting plate. The tail end of the industrial robot passes through the notch and is connected to the mounting plate, thereby controlling the movement direction and position of the housing picking fixture;

[0029] The connecting device 2 comprises a long rod 21, an auxiliary rod 22, a bolt 23, a limiter 24 and a ring body 25. The two long rods are provided with a support rod 211 which is hollow inside and has a spring 212 on the outer wall. The two auxiliary rods are hollow inside and shorter than the support rods. The bolt 23 can pass through the opening 12 of the mounting plate and be placed inside the auxiliary rod. The limiter is provided with a convex ring (not marked) and is a hollow cylinder which can be sleeved on the outer wall of the support rod. After the limiter is sleeved on the support rod, it is placed in the stepped hole. One end of the long rod is fixed to the mounting plate 1 through the limiter and protrudes from the mounting plate, and the other end is fixed to the profiling structure 3 by bolts. The hollow cylinder of the ring body 25 is provided for the auxiliary rod to be assembled. One end of the auxiliary rod is fixed to the mounting plate 1 by bolts, and the other end is fixed to the profiling structure 3 by the ring body 25.

[0030] The profiling structure 3 is provided with four placement cavities (not marked), and the adjacent placement cavities are connected and the connection is provided with countersunk holes 31 and through holes 35, and there are two countersunk holes and two through holes, and the annular body 25 is adapted to the countersunk holes, and the bolts 23 are adapted to the through holes. A circular hole 33 and two tracheal ports 32 are provided at the bottom of each placement cavity. The tracheal ports are connected to the pneumatic device and the trachea passes through the through hole 13 above the placement cavity. The circular hole passes through the bottom of the placement cavity, and the through hole (not marked) for placing the tracheal port also passes through the bottom of the placement cavity. The suction cup 34 is adapted in the through hole and connected to the tracheal port. Two suction cups are provided in each placement cavity and are diagonally distributed on both sides of the circular hole to provide stable suction;

[0031] The injection molding machine once injection molds four housings 4, and each housing is provided with an annular portion 41 at the rear end. After the housing is injection molded, the housing pick-up fixture moves to the vicinity of the housing, the pneumatic device is turned on, the suction cup generates suction, and the injection molding machine provides the housing with a force to move toward the housing pick-up fixture. The mounting plate 1 is stationary, the housing is pushed into the corresponding placement cavity, the length of the support rod and the auxiliary rod between the mounting plate and the profiling structure is shortened, and the profiling structure drives the support rod 211 to move relative to the mounting plate, the spring 212 is compressed, and the auxiliary rod moves relative to the profiling structure 3. The profiling structure using the above structure has a certain range of motion, and the limiter and the annular body are respectively provided with a convex ring 241 and a snap ring 251, so that when the support rod and the auxiliary rod move, the limiter and the annular body are not easy to fall off from the stepped hole 14 and the countersunk hole 31;

[0032] After the casing is assembled with the contouring structure, the industrial robot drives the mounting plate to move away from the contouring structure, the spring recovers, the distance between the mounting plate and the contouring structure returns to the original distance, and the industrial robot drives the casing removal fixture and the casing to move to the placement position. At this time, the pneumatic device is turned off, the suction force of the suction cup disappears, and the casing falls off from the contouring structure.

[0033] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0034] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
