Detailed Implementation Methods

[0030] Example 1:

[0031] Please refer to Figures 1-7 This embodiment is an automatic assembly device 100 for a bacterial collector cap, which includes a conveyor line 4, a carrier 5 conveyed on the conveyor line 4, a cap assembly station and a cap dispensing station arranged sequentially along the conveyor line 1, a cap feeding mechanism 1 and a cap assembly and transporting mechanism 2 arranged at the cap assembly station, and a cap dispensing mechanism 3 arranged at the cap dispensing station.

[0032] The microbial collector 200 in this embodiment includes a cup assembly 201, a guide tube 202 and a protective cap 203 disposed on the top of the cup assembly 201. The cup assembly 201 includes a cup body 2011, a base 2012 disposed at the bottom of the cup body 2011 and a top cover 2013 disposed on the top of the cup body 2011. The guide tube 202 is disposed on a guide tube column 20111 on the top of the cup assembly 201, and the protective cap 203 is disposed on the exhaust pipe 20131 of the top cover 2013.

[0033] The cap feeding mechanism 1 includes a vibratory feeder 11, a material distribution module 12 located at the end of the vibratory feeder 11, a cap loading mechanism 13 that takes out caps 203 from the material distribution module 12, and a transfer feeding component 14 that receives a set of caps 203 at the cap loading mechanism 13 and then transfers them to the cap assembly and handling mechanism 2.

[0034] The material distribution module 12 receives one protective cap 203 output from the vibratory feeder 11 each time and cuts it out.

[0035] The cap feeding mechanism 13 includes a first cylinder 131, a first support plate 132 driven by the first cylinder 131 to move horizontally, a second cylinder 133 fixed on the first support plate 132, and a cap suction nozzle 134 driven by the second cylinder 133 to move up and down. The first support plate 132 is switched between the picking position and the discharging position by the first cylinder 131.

[0036] The transfer and feeding assembly 14 includes a driving member 141 and a second support plate 142 driven by the driving member 141 to move horizontally. A plurality of cap-limiting grooves 143 are arranged on the second support plate 142 along its direction of movement. The cap-limiting grooves 143 receive caps and limit their position. The driving member 141 enables the second support plate 142 to switch between a receiving position and a feeding position. At the receiving position, the second support plate 142 receives caps from the cap feeding mechanism 13; at the feeding position, it supplies caps to the cap assembly and conveying mechanism 2.

[0037] The cap assembly and handling mechanism 2 includes a two-axis transfer assembly 21, a third support plate 22 located at the movable end of the two-axis transfer assembly 21, a cap picking module 23 and a straightening module 24 fixed on the third support plate 22.

[0038] In this embodiment, the alignment module 24 and the cap picking module 23 are jointly disposed at the movable end of the biaxial transfer assembly 21. In other embodiments, the alignment module 24 may also be disposed separately at the cap assembly station, and a linear transfer module may be configured to drive the alignment module 24 to switch between a working position and a clearance position. In the working position, the alignment module 24 corrects the angle of the cup assembly 201; in the clearance position, it clears the space above the cup assembly 201 to allow the cap picking module 23 to assemble the cap.

[0039] The alignment module 24 includes a fourth support plate 246, a third cylinder 241 fixed on the fourth support plate 246, an active swing rod 242 driven by the third cylinder 241 to swing around the Z-axis at one end, and several driven swing rods 243 rotatably mounted on the fourth support plate 246 at one end. The other end of the active swing rod 242 and the other end of the driven swing rods 243 are connected together by a connecting rod 244 to achieve linkage. The lower surfaces of both the active swing rod 242 and the driven swing rods 243 are provided with alignment plates 245. All alignment plates 245 are arranged and correspond to the positions of the cup assembly 201 on the carrier 6. The fourth support plate 246 is fixed on the third support plate 22. When adjusting the angle and position of the cup assembly 201, the straightener 245 extends between the exhaust pipe 20131 and the guide pipe column 20111. Then, by swinging, one end of the straightener 245 moves the exhaust pipe 20131 and the other end moves the guide pipe column 20111, thereby causing the cup assembly 201 to rotate on the carrier 5, thus achieving the angle and position adjustment.

[0040] The position of the protective cap is changed through the two-axis transfer component 21. The protective cap is picked up and assembled through the protective cap picking module 23. The horizontal angle position of the cup body component 201 on the carrier 5 is adjusted and corrected through the alignment module 24, laying an important foundation for the precise assembly of the protective cap 203.

[0041] Multiple sets of cap-collecting modules 23 are arranged on the third support plate 22, and include a collecting rod 231 fixed to the lower surface of the third support plate 22, a discharging sleeve 232 that is movably mounted on the third support plate 22 and sleeved around the collecting rod 231, and a fourth cylinder 233 fixed to the third support plate 22 and driving the discharging sleeve 232 to move up and down. In the collecting state, the bottom of the collecting rod 231 extends beyond the discharging sleeve 232, and the extended part is inserted into the perforation of the cap 203 to collect the material from the cap. In the discharging state, the discharging sleeve 232 moves downward along the outer periphery of the collecting rod 231, pushing the cap 203 on the collecting rod 231 downward, and then installing the cap 203 onto the exhaust pipe at the top of the cup body 2011 to obtain the bacteria collector 200.

[0042] The cap dispensing mechanism 3 includes a three-axis transfer assembly 31, a fifth support plate 32 located at the movable end of the three-axis transfer assembly 31, and a camera 33 and a dispensing gun 34 fixed on the fifth support plate 32. The three-axis transfer assembly 31 enables the spatial movement of the fifth support plate 32, facilitating the dispensing of caps onto multiple cup components 201. The camera 33 accurately acquires the position of the cap on each cup component 201, providing precise positional information for dispensing.

[0043] Downstream of the cap dispensing station on conveyor line 4, there is also an adhesive curing station. This station is equipped with an adhesive curing mechanism 6, primarily used to cure the adhesive applied to the cap. The adhesive curing mechanism 6 is a thermosetting mechanism, comprising a protective cover and a thermosetting module housed within the cover. The thermosetting module can use various non-contact heating methods such as electric heating, infrared heating, and ultrasonic heating to cure the adhesive.

[0044] The workflow of the automatic assembly device 100 for the bacterial collector cap in this embodiment is as follows: The carrier 5 carries a set of cup body components 201 and moves them to the cap assembly station; the cap feeding mechanism 1 supplies a set of caps 203, which are moved to the feeding station via the transfer feeding component 14; the cap assembly and transport mechanism 2 takes out a set of caps 203 from the transfer feeding component 14, and then moves the upper part of the cup body component 201, while the alignment module 24 adjusts the angle and position of the cup body component 201 to the set position. In the following steps: The cap picking module 23 assembles the cap 203 onto the exhaust pipe 20131 on the cup body assembly 201; then, the carrier 5 moves to the cap dispensing station, the camera 33 acquires the position of the cap 203 on the cup body assembly 201, and then the dispensing gun 34 dispenses glue at the corresponding position; then the carrier 5 moves to the glue curing station, and the glue curing mechanism 6 cures the glue, fixing the cap 203 onto the exhaust pipe 20131, thus completing the cap assembly.

[0045] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
