DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0038] Please refer to Figure 1-3 , the overall view, exploded view and magnified view of the assembly state of the dropper of the present invention are shown in the figure, which shows that the dropper includes a cover S1, a rubber head S2 and a glass tube S3. At the position marked A, a groove is provided on the cover S1, and the bottom end of the rubber head S2 is clamped in the groove; at the position marked B, the top diameter of the glass tube S3 is larger than the bottom diameter, and the end with the larger diameter is used as a snap-fit ​​structure to buckle with the components of the cover S1 and the rubber head S2.

[0039] Please refer to Figure 4-5 The present invention discloses an automatic dropper assembly machine, comprising a workbench 1, a turntable 11 disposed thereon, and a positioning fixture 12 on the turntable 11, wherein a feeding mechanism, an auxiliary mechanism, and a discharging mechanism are disposed along the workbench 1;

[0040] The feeding mechanism includes a cap conveyor belt 21, a glue head transmission device, a glass tube conveyor chain 42 and a manipulator device, and the auxiliary mechanism includes a cap pressing device 24, a glue pressing head device 37 and a glue pulling head device 38;

[0041] The robot device includes a cap robot 23, a rubber head mechanical rod 36 and a glass tube robot 41. The cap robot 23 is arranged on the side of the cap conveyor belt 21, the rubber head mechanical rod 36 is arranged on the side of the material dividing piece 35, and the glass tube robot 41 is arranged on the side of the glass tube conveyor chain 42, respectively clamping the cap S1, the rubber head S2 and the glass tube S3;

[0042] The discharging mechanism includes a finished product discharging device 5 and a defective product discharging device 6, and the defective product discharging device 6 is arranged on the side of the finished product discharging device 5;

[0043] The cover conveyor belt 21 transports the cover S1 to the edge of the workbench 1, the robot device clamps the cover S1 into the positioning fixture 12 of the turntable 11, the cover pressing device 24 fixes the cover S1 in the positioning fixture 12, the rubber head transmission device transports the rubber head S2 to the edge of the workbench 1, the robot assembly places the rubber head S2 in the cover S1 of the positioning fixture 12, the rubber head pressing device 37 pushes the rubber head S2 into the cover S1, the rubber head pulling device 38 further fixes the rubber head S2 in the cover S1, the glass tube conveyor chain 42 sends the glass tube S3 to the edge of the workbench 1, the robot device fixes the glass tube S3 on the cover and rubber head assembly of the positioning fixture 12, the assembled dropper S3 enters the discharging mechanism for delivery, the finished product enters the finished product discharging device 5, and the defective product enters the defective product discharging device 6.

[0044] For details, please refer to Figure 6-7 The cover conveyor belt 21 includes a supporting frame 211, a conveyor belt 212, and a motor. One end of the conveyor belt 212 is arranged on the workbench 1, and the other end is supported by the supporting frame 211. The motor drives the conveyor belt 212 to rotate. Four channels 8 are arranged on the conveyor belt 212. Each channel 8 limits the transportation of a column of covers S1. Most of the existing conveyor belts are not provided with channels. The products are directly placed on the conveyor belt 212. When it is used for dropper assembly, individual products need to be assembled. It is not enough to only solve the problem of transporting the covers to the workbench 1. The robot device cannot accurately take out the covers S2 from the conveyor belt 212 full of covers S1. Therefore, the cover conveyor belt 21 is provided with 4 channels 8, which match the number of slots 121 of the positioning fixture 12. If the number of slots in the positioning fixture 12 is 6, the number of channels is also increased to 6 accordingly.

[0045] The caps S1 are designed to be transported to the workbench 1 in a row of 4 columns. There is another problem, that is, the spacing between the manipulators can be designed according to the spacing between the slots 121 on the positioning fixture 12, but the manipulators also need to match the distance between the caps arranged on the channel 8 of the conveyor belt 212; at the same time, it is necessary to ensure that the manipulators accurately clamp the caps S1 to the positioning fixture 12.

[0046] Therefore, a telescopic device 22 is provided between the cover manipulator 23 and the cover conveyor belt 21, and the telescopic device 22 includes a telescopic cylinder 221, a telescopic rod 222 and a platform 223. The telescopic rod 222 passes through the platform 223, and the telescopic cylinder 221 drives the telescopic rod 222, and the platform 223 is laterally opened and closed, so as to grab the cover S1 to the cover conveyor belt 21 and then transition to the positioning fixture 12 through the platform 223. In the figure, it can be seen that the width of the conveyor belt is inconsistent with the width of the positioning fixture 12, so after the cover is clamped from the cover conveyor belt 21, the cover needs to be placed on the telescopic device 22. The telescopic device 22 has two functions: one is the positioning function, which makes the position of the platform 223 correspond to the position of the slot 121 of the positioning fixture 12; the second is to ensure that the cover S1 can be accurately clamped into the positioning fixture 12.

[0047] Reference Figure 8 The cover manipulator 23 clamps the cover S1 to the positioning fixture 12 and can accurately drop it to the position, but it cannot guarantee that all the covers can be stably placed in the slots of the positioning fixture. Therefore, it is necessary to add a cover pressing device 24, which includes a cover pressing cylinder 241, a parallel plate 242 and a baffle 243. The parallel plate 242 is arranged below the cover pressing cylinder 241, and the baffle 243 is arranged on the side of the parallel plate 242 and blocks the positioning fixture 12. The cover pressing cylinder 241 drives the parallel plate 242 and the baffle 243 to move longitudinally to press the cover S1 into the positioning fixture 12.

[0048] When the cap enters the positioning fixture, the rubber head needs to be transported into the cap. Because the rubber head is soft, it is not convenient to transport it neatly and orderly; at the same time, how to transport the rubber head into the cap is the most difficult problem to be solved in this equipment.

[0049] Please refer to Fig. 9 The rubber head transmission device adopts a material bin 31, a vibration plate 32, a pusher 33, a material trough 34 and a material dividing piece 35. The rubber head S2 is placed in the material bin 31, and the rubber head S2 enters the vibration plate 32 through the material bin 31. The vibration plate 32 arranges the rubber heads in an orderly manner and enters the pusher 33. The pusher 33 sends the rubber heads individually into the material trough 34, and then sends them to the dividing piece 35 through the material trough 34. The dividing piece 35 arranges the rubber heads and waits for the robot device to clamp them.

[0050] The silo 31 includes a feed port 311, a discharge port 312 and a straight vibrator 313. The feed port 311 is arranged at the top of the silo 31, the discharge port 312 is arranged at the side of the silo 31, and the straight vibrator 313 is arranged at the connection between the feed port 311 and the discharge port 312. The rubber head is poured into the silo 31 from the feed port 311. The silo 31 is a containing barrel. The straight vibrator 313 generates an exciting force to vibrate the rubber head S2, thereby causing the vibrated rubber head to flow out from the discharge port 312.

[0051] The vibration plate is composed of a hopper and a chassis. As shown in the figure, the hopper used in the present invention is a cylindrical hopper, and its working principle is as follows: the chassis is provided with a pulse electromagnet, which can make the hopper vibrate in the vertical direction, and the inclined spring sheet drives the hopper to perform torsional vibration around its vertical axis; the rubber head in the hopper rises along the spiral track due to the vibration; during the rising process, after a series of track screening or posture changes, the rubber head can automatically enter the assembly or processing position in a unified state according to the requirements of assembly or processing; its working purpose is to automatically and orderly arrange the disordered rubber heads in a directional manner through vibration, and transport them to the next process accurately.

[0052] Furthermore, a sensor 321 is provided in the vibration plate 32 , and the sensor 321 is used to sense whether there is a rubber head in the vibration plate 32 .

[0053] Reference Figure 10-11 , the position of the rubber head in the figure is a slot, and the rubber head is dropped into the slot through the vibration disk, and a pusher 33 is arranged at the outlet 322 of the vibration disk 32, and the pusher 33 includes a foot seat 331 and a push rod 332, a push rod cylinder 333, a blow pipe cylinder 334, and a blow pipe 335 arranged on the foot seat 331, and the push rod 332 penetrates into the rubber head S2, and the head of the push rod contacts the bottom surface of the rubber head. When the push rod is upward, the rubber head is lifted up; the push rod cylinder 333 drives the push rod 332 to move longitudinally, and the blow pipe cylinder 334 is arranged on the opposite side of the push rod cylinder 333, and the blow pipe cylinder 334 drives the blow pipe 335 to move longitudinally. In the figure, the air pipe is connected to the lower part of the mark C to introduce gas to the blow pipe 335, and from the material trough 34 to the material dividing piece 35. Blow pipe principle: the blow pipe 335 and the push rod 332 move upward synchronously to ensure that the rubber head does not sink; a hole is drilled in the blow pipe 335, and the rubber head S2 is blown to a deeper part of the material trough 34 through positive pressure; the working sequence of the pusher is: (1) first push the push rod upward (2) then push the blow pipe upward (3) and finally blow air.

[0054] from Fig. 9 It can be seen that the material trough 34 is divided into two channels, which is the same number as the push rod 332. The material trough 34 includes an inlet and an outlet. The inlet is arranged above the pushing piece 33, and the outlet is arranged above the dividing piece 35. The material trough 34 is "U"-shaped, and the blowpipe 335 pushes the rubber head S2 individually from the inlet to the outlet of each channel to the dividing piece 35.

[0055] Reference Fig.12 The material dividing member 35 includes a slide rail base 351, a slide rail cylinder 352, a glue head fixture 353 and a moving cylinder 354. The slide rail cylinder 352 is connected to the slide rail base 351, the glue head fixture 353 is arranged on the slide rail base 351, and the moving cylinder 354 is connected to the glue head fixture 353. The slide rail cylinder 352 drives the glue head fixture 355 to move to the bottom of the material trough 34 or move out of the bottom of the material trough 34. The rubber head holding jig 353 is provided with four slots, and the rubber head S2 on the material slot 34 falls into the rubber head holding jig 353 in a staggered manner. The implementation principle is: the rubber head holding jig 353 is driven by the moving cylinder 354 to arrange the slots on the rubber head holding jig 353, and the rubber head S2 first enters the 1st and 3rd slots. When the moving cylinder 354 drives the rubber head holding jig to move horizontally, the rubber head falls into the 2nd and 4th slots.

[0056] Reference Figure 13-14 The rubber head mechanical rod 36 includes a transverse slide rail 361, a longitudinal slide rail 362, a mechanical rod cylinder 363 and a material picking rod 364. The material picking rod 364 connects the transverse slide rail 361 and the longitudinal slide rail 362. The transverse slide rail 361 and the longitudinal slide rail 362 are both provided with cylinders. The cylinder drives the material picking rod 364 to move transversely along the transverse slide rail 361 and drives the material picking rod to move longitudinally along the longitudinal slide rail 362. The diameter of the material picking rod 364 is roughly the same as the internal diameter of the rubber head. The material picking rod 364 is tightly matched with the rubber head to lift the rubber head in the rubber head fixture 353, thereby moving the rubber head. When the rubber head is buckled with the cover, the material picking rod 364 can be taken out. The mechanical rod cylinder 363 includes a material taking cylinder 3631 and a material stripping cylinder 3632. The rubber head mechanical rod 36 places the rubber head into the positioning fixture, the material stripping cylinder 3632 moves down to press the rubber head, and the taking and placing cylinder 3631 is closed, thereby realizing the action of loading the rubber head.

[0057] Reference Fig.15 The glue head device 37 includes a column 371 and a column cylinder 372. The column 371 is arranged above the positioning fixture 11. The column cylinder 372 drives the column 371 to move longitudinally to push the glue head S2 in the positioning fixture 12 into the cover S1.

[0058] Reference Fig.16The rubber head pulling device 38 includes a pressure plate 381, a clamp 382, ​​a clamp cylinder 383, a large cylinder 384 and a small cylinder 385. The pressure plate 381 is arranged above the positioning fixture 12, and the clamp 382 is arranged below the positioning fixture 12. The small cylinder 385 moves up to the rubber head S2 position, and the clamp 382 clamps the rubber head; then the large cylinder 384 moves downward to realize the rubber head pulling action; then it returns to the initial position, the clamp 382 is released, and the small cylinder 38 5 moves down, and the large cylinder 384 moves up; the large cylinder 384 and the small cylinder 385 drive the pressure plate 381, the clamp 382 and the clamp cylinder 383 to move longitudinally, and the pressure plate 381 blocks the rubber head and pops out, and the clamp cylinder 383 drives the clamp 382 to clamp the rubber head, and clamps the rubber head in the positioning fixture 12 on the lid; when the material is waiting, the large cylinder opens, and the small cylinder opens, so that there is enough space between the clamp and the pressure plate, and the turntable rotates without interference. Due to the material of the rubber head, the large cylinder pulls down about 10mm, and the rubber head is in place. If the large cylinder is forced to pull down more than 28mm, it may damage the rubber head. Since the large cylinder pulls down about 10mm, the turntable will interfere. Therefore, after the large cylinder is pulled, the small cylinder moves down to ensure no interference. When the turntable turns to the rubber head pulling device, the large cylinder closes, the small cylinder closes, and reaches a height that can clamp the rubber head; the clamp cylinder closes and clamps the rubber head; then the clamp cylinder resets and fully opens to complete the rubber head pulling action.

[0059] Reference Figure 17-18 A plurality of glass tube fixtures 421 are provided on the glass tube conveyor chain 42, and an electric eye detection bracket 43 is provided on the side of the glass tube conveyor chain 42. The electric eye detection bracket 43 is used to detect whether a glass tube is installed on the glass tube fixture.

[0060] A clamping cylinder 44 is also provided on the side of the glass tube conveying chain 42 , and the glass tube S3 on the positioning fixture 12 is clamped by the clamping cylinder 44 , so that the glass tube manipulator 41 can fix the glass tube on the assembly of the cover and the rubber head.

[0061] The finished product discharging device 5 includes a finished product manipulator 51 and a finished product conveyor belt 52, and the finished product manipulator 51 clamps the dropper to the finished product conveyor belt 52. The defective product discharging device 6 includes a defective product manipulator 61 and a chute 62, and the defective product manipulator 61 clamps the defective product to the chute 62.

[0062] Furthermore, a residual material detection device 7 is provided on the side of the defective product discharging device, which senses whether there is any dropper material that has not been clamped away on the positioning fixture through the induction principle, and transmits the information to the control center.

[0063] The above-mentioned control center is a necessary component for each mechanical equipment. The program is input into the control center, and the control center receives instructions and collected information to make feedback control.

[0064] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
