Description

Technical Field

The last step of packaging is capping. The current capping equipment, for example, the patent previously applied by the applicant, 201820099451.9, discloses a sample bottle automatic encapsulation device, which includes: an upper cap mechanism for conveying the bottle caps; an X-Y moving module arranged above the upper cap mechanism, and a capping mechanism is arranged on the X-Y moving module, which clamps and transports a bottle cap of the upper cap mechanism to a preset position above the sample bottle and screws the bottle cap onto the sample bottle. The opening and capping mechanism grabs the cap from the upper cap mechanism, then moves above the sample bottle for capping. It is found in the use process that since the caps on the cap placing mechanism are stacked in a stack, it is very difficult for the capping mechanism to keep the bottle caps horizontal when grabbing. Once the grabbed bottle cap cannot be kept horizontal, then capping is likely to produce misalignment or capping failure. Therefore, it will affect the automatic operation of sample preparation.

The cap can be taken from the cap covering mechanism 7 through the vacuum suction cup 13.

[0023] See Figure 4, the lid opening and closing mechanism 3 includes: a lifting module 31 provided on the first mounting base 8, the telescopic end of the lifting module 31 is connected to a second mounting base 36. The second mounting base 36 includes a horizontal plate 361 and a vertical plate 362 connected to the lifting module 31. The horizontal plate 361 is provided at the lower end of the vertical plate 362. Two side plates 363 are connected between the horizontal plate 361 and the vertical plate 362. A rotary motor 32 is provided on the horizontal plate 361. The end of the output shaft of the rotary motor 32 is provided with a driving gear 331.

A driven gear 332 meshing with the driving gear 331 is provided on the rotary shaft 37. Four lid opening and closing cylinders 34 are provided at the lower end of the rotary shaft 37. The free end of the lid opening and closing cylinder 34 has a jaw 35. The rotary motor 32 drives the rotary shaft 37 and the jaws 35 provided on the rotary shaft 37 to rotate together through the driving gear 331 and the driven gear 332. When closing the lid, the lifting module 31 drives the second mounting base 36 and the components on the second mounting base 36 to move downward above the bottle cap. The lid opening and closing cylinder 34 drives the jaws 35 to open. The lid opening and closing cylinder 34 is also called a lid opening and closing finger. It continues to descend to the lid placing platform 2. The lid opening and closing cylinder 34 drives the jaws 35 to close to grab the bottle cap. Then, the lifting module 31 rises. The horizontal moving module 5 drives the lid opening and closing mechanism 3 to move above the sample bottle fixing mechanism 9, descends to close the lid, and the rotary motor 32 rotates to drive the rotary shaft 37 and the jaws 35 to rotate to close the lid.

[0024] Further, referring to Figure 5 , the lid detecting mechanism 4 includes: a cylinder 41 fixed to the first mounting base 8 through a connecting seat 44. The connecting seat 44 includes a vertical plate 441 vertically connected to the first mounting base 8 and a flat plate 442 vertically provided at the front end of the vertical plate 441. The cylinder 41 is provided on the flat plate 442. An inductor mounting bracket 42 is provided at the lower telescopic end of the cylinder 41. The inductor mounting bracket 42 has three uniformly distributed mounting vertical surfaces 421 for mounting. Three inductors 43 are mounted on the mounting vertical surfaces 421 of the inductor mounting bracket 42. After the lid closing is completed, the horizontal moving module 5 drives the lid detecting mechanism 4 above the sample bottle fixing mechanism 9. The cylinder 41 descends. The inductor 43 is used to detect whether there is a bottle cap on the sample bottle and whether the bottle cap is installed flatly.

[0025] A collection box for collecting waste lids is also provided on the frame. The sample bottle fixing mechanism 9 includes a second lid opening and closing cylinder 91 and jaws two 92 located at the upper end of the second lid opening and closing cylinder 91, for holding the sample bottle. The second lid opening and closing cylinder 91 is an off-the-shelf lid opening and closing finger.

[0026] Referring to Figure 1, the upper cover mechanism 7 is used to store and provide bottle caps. It includes 4 cap holding barrels arranged on a disc, which adopts the structure disclosed in the prior patent 201820099451.9 and will not be elaborated here. One of the cap holding barrels rotates to the side adjacent to the cap placing platform 2, and the horizontal movement module 5 drives the cap picking mechanism 1 to move above the cap holding barrel, as Figure 6 shown. The cap picking mechanism 1 picks up a bottle cap, then moves above the cap placing platform 2, as Figure 7 shown, and releases the bottle cap onto the cap placing platform 2. Then, the cap opening and closing mechanism 3 moves above the cap placing platform 2, as Figure 8 shown, grabs the bottle cap, as Figure 9 shown. Then, the cap opening and closing mechanism 3 moves above the sample bottle fixing mechanism 9, as Figure 10 shown, and performs cap closing. After the cap closing is completed, the horizontal movement module 5 drives the cap detecting mechanism 4 to move above the sample bottle fixing mechanism 9, as Figure 11 shown, to detect whether there is a bottle cap on the sample bottle and whether the bottle cap is screwed on flatly.

[0027] For the novel cap picking and closing device of the present utility model, since the cap picking mechanism and the cap placing platform 2 are added, the cap opening and closing mechanism 3 grabs the bottle cap on the cap placing platform 2. The position of the bottle cap is flat, and the cap opening and closing mechanism 3 will keep the bottle cap in a horizontal state when grabbing the bottle cap, so it will not tilt, and there will be no misalignment or cap closing failure during the cap closing process, thus greatly improving the accuracy of cap closing.

[0028] The above description is illustrative rather than restrictive for the present utility model. The present utility model aims to provide a novel cap picking and closing device, which picks the cap twice. One time is to pick the cap from the upper cover mechanism in the vacuum chuck and place it on the cap placing platform 2, and then pick the cap from the cap placing platform 2 through the cap opening and closing mechanism 3, and then perform cap closing. It can reduce the error rate of cap closing. Those of ordinary skill in the art understand that without departing from the spirit and scope defined by the claims, many modifications, changes or equivalents can be made, such as the structures of the upper cover mechanism and the cap placing platform 2, etc., but they will all fall within the protection scope of the present utility model.
