Taking the conventional production of bacterial culture plates as an example, when a mold is used for injection molding, a set of mold is used for simultaneously injection molding a base and an upper cover, a manipulator takes out an injection molded product from the mold and then places the injection molded product on a workbench, two workpieces of the base and the upper cover are buckled together manually, and then the product is placed into a plastic package bag. The risk of contamination is great during this process because of the high number of workers touching the parts. It is generally required that the glove worn by the worker must be replaced after half an hour of use, and that the glove must not touch objects other than the product during use.

The special cover closing machine is widely used at present, and after the mechanical arm takes out the product, the product is placed on a jig of the machine, and the machine falls into the plastic package bag after closing the cover.

The utility model relates to a manipulator injection molding part cover closing jig with an automatic cover closing function, which realizes the functions of taking out, overturning and cover closing of an injection molding part, does not need other machine stations and manual operation, effectively improves the product quality and saves the cost.

Specifically, the method comprises the following steps: the jig comprises a vacuum suction mechanism, a turnover mechanism and a cover closing mechanism, wherein the vacuum suction mechanism is used for taking out an injection molding piece from a die, the turnover mechanism is used for turning the upper cover 12 clockwise for 180 degrees, and the cover closing mechanism is used for horizontally moving the base 13 to be buckled with the upper cover 12.

The vacuum suction mechanism is characterized in that a base sucker 5 is arranged on a base 13 which is profiled according to the outline of a product, and the positioning accuracy of the product is ensured while the product is sucked through the base sucker 5. The base chuck 5 is a vacuum chuck.

As shown in fig. 5 to 6, the tilting mechanism is driven by a rack and pinion mechanism to rotate the opening direction of the upper cover 12 clockwise by 180 °, and alignment of the upper cover 12 and the base 13 is completed.

The cover closing mechanism moves the base 13 rightward, and the base 13 and the upper cover 12 are completely buckled.

After closing the cover, the base sucker 5 breaks vacuum, and the cover closing mechanism retreats, so that the product falls into a plastic package bag which is placed manually in advance in a cover closing state. After the product falls into the plastic package bag, the bag opening is manually sealed, and the product processing is completed.

Referring to fig. 1 to 3, the jig is composed of a rack driving cylinder 1, a rack 2, a gear 3, a base profile plate 4, a base suction cup 5, a rotating shaft 6, an upper cover suction cup 7, an upper cover profile plate 8, a manipulator mounting flange 9, a base driving cylinder 10, a base buckling cylinder 11 and the like.

The main function of the manipulator mounting flange 9 is to connect with the manipulator of the injection molding machine. The jig is connected with the manipulator through a screw hole on the manipulator mounting flange 9, and the manipulator moves with the jig in space. After the injection of the mold is completed, the mold is opened. The manipulator brings the jig into the mold, and removes the base 13 and the upper cover 12 from the mold. After the product is taken down, the manipulator moves outside the die with the jig, and in the moving process, the base 13 and the upper cover 12 complete the cover closing action.

Referring to fig. 4, when the jig takes the base 13 and the upper cover 12 from the mold, the base driving cylinder 10 is in an extended state, the base fastening cylinder 11 is in a retracted state, and the rack driving cylinder 1 is in a retracted state. The upper cover sucker 7 arranged on the upper cover profiling plate 8 sucks the upper cover 12 through vacuum, and the base sucker 5 arranged on the base profiling plate 4 sucks the base 13. It can be seen that the base 13 is to the right of the upper cover 12, and that a direct flip of the upper cover would collide with the base.

Referring to fig. 5, the base driving cylinder 10 is retracted, moving the base 13 to the left of the upper cover 12.

Referring to fig. 6, the rack driving cylinder 1 is extended, the linear motion of the rack 2 is converted into the rotational motion of the gear 3 by the gear 3 engaged therewith, the gear drives the rotation shaft 6 to rotate, and the rotation shaft 6 drives the upper cover cam 8 to rotate 180 ° clockwise. The turned upper cover 12 and the base 13 are in an aligned state, and the opening of the upper cover 12 faces the base 13.

Referring to fig. 7, the base buckling cylinder 11 extends to drive the base profiling plate 4 to move rightwards, and the base 13 and the upper cover 12 complete the closing.

In the present utility model, the upper cover 12 and the base 13 are formed with a step (i.e., staggered) when they are injection molded into a mold (not shown): as shown in fig. 4, the base 13 is further to the right, and the upper cover 12 is further to the left. As shown in fig. 5, the base driving cylinder 10 is configured to move the base 13 to the left of the upper cover 12 (by driving the connecting member 18 to move the frame ii 17 in a left-to-left translation relative to the frame i 14). Thus, as shown in fig. 6, the upper cover 12 can not interfere after being turned over, the upper cover 12 and the base 13 are not collided, and the rear cover can be closed more easily. After the base 13 is moved to the left, the upper cover 12 is turned 180 ° so that the upper cover 12 and the base 13 are aligned, and only without being snapped. Then the base 13 moves to the right for a small distance under the movement of the base buckling cylinder 11, and the base 13 and the upper cover 12 are buckled.

According to the utility model, the plastic package bag is manually sleeved on the lower half parts of the buckled base 13 and upper cover 12, the base buckling cylinder 11 retracts, the base sucker 5 and upper cover sucker 7 release vacuum, and products fall into the plastic package bag. The product falls into the plastic package bag, namely the processing of one product is completed, and before the next product is processed, the base driving cylinder 10 is extended and the rack driving cylinder 1 is retracted, namely the initial state is returned.

The utility model, not described in detail, is well known or known in the art.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
