[0054] The following are arranged on the frame 17 and along the circumference of the main turntable 1 in sequence: a porcelain tube feeding mechanism 3, an inner cap pre-pressing device at one end 4, an inner cap pressing device at one end 5, a porcelain tube turning device 6, a visual inspection device at one end 7, an inner cap correction device at one end 8, inner cap pre-pressing mechanisms at both ends 9, inner cap pressing devices at both ends 11, a length detection device 12, and a finished product unloading mechanism 13.

[0055] like Figure 3 and Figure 4 As shown, the porcelain tube feeding mechanism 3 includes a tube elevator 301, a conveyor belt 302 and a feeding rotating device 303. The tube elevator is used to transport the porcelain tube 14 to the conveyor belt 302. The tube elevator 301 has several layers of inclined pushing guide plates in the material bin; the feeding rotating device 303 is connected to one end of the conveyor belt 302 facing the main turntable 1, and a feeding clamp 304 is rotatably connected to the feeding rotating device 303. A rotating cylinder 605 is arranged in the feeding rotating device 303, and the feeding clamp 304 is driven to rotate by the rotating cylinder 605; a travel limit block 305 is also arranged at the end of the conveyor belt 302, and when the porcelain tube 14 moves to the end of the conveyor belt 302, it abuts against the travel limit block 305 to prevent the porcelain tube 14 from falling.

[0056] Working principle: The pipe elevator 301 lifts the porcelain tube 14 in the silo upwards layer by layer to the conveyor belt 302, and the conveyor belt 302 conveys the porcelain tube 14 in the direction of the product clamp 2. When the porcelain tube 14 moves to abut against the travel limit block 305, the loading clamp 304 clamps the porcelain tube 14 and flips it to a vertical state, so that the middle position of the porcelain tube 14 is just in the middle of the arc of the product clamp 2. After the product clamp 2 is closed, the loading clamp 304 flips back to its original position, and the loading of the porcelain tube 14 is completed.

[0057] like Figure 5 As shown, the inner cap prestressing device 4 at one end includes a prestressing base 401, an inner cap guide block 402 is arranged on the prestressing base 401, a prestressing push rod 403 is movably arranged below the inner cap guide block 402, and a prestressing limit block 404 is arranged above it, a through hole corresponding to the shape of the inner cap 15 is penetrated through the middle of the inner cap guide block 402, so that the prestressing push rod 403 can lift the inner cap 15 in the inner cap guide block 402, and a prestressing cylinder 405 for driving the prestressing push rod 403 is installed below the prestressing base 401, and the cylinder head of the prestressing cylinder 405 drives the prestressing push rod 403 to move up and down toward the upper side.

[0058] The inner cap pre-pressing device 4 at one end also includes an inner cap feeding vibration disk 406 at one end, and a feeding track is connected to the inner cap feeding vibration disk 406 at one end, and the feeding track is connected to the inner cap 15 guide block 402, and the inner cap 15 in the inner cap feeding vibration disk 406 at one end is transported to the inner cap guide block 402 through spiral vibration, and a blowing hole for blowing is also provided at the lower end of the feeding track, so that the inner cap 15 can enter the inner cap guide block 402 faster.

[0059] Working principle: The product clamp 2 clamps the porcelain tube 14 and rotates to the inner cap preloading device 4 station at one end. At this time, there is a certain distance between the upper end face of the porcelain tube 14 and the preloading limit block 404, and the cylinder head of the preloading cylinder 405 moves upward, so that the preloading push rod 403 pushes the inner cap 15 in the inner cap guide block 402 upward into the lower end face of the porcelain tube 14. The upper end face of the porcelain tube 14 fits with the preloading limit block 404, completing the preloading of the inner cap 15 at one end.

[0060] like Figure 6 As shown, the inner cap pressing device 5 at one end includes a pressing base 501, a pressing limit block 502 is arranged on the pressing base 501, a pressing push rod 503 is movably arranged below the pressing limit block 502, and a pressing cylinder 504 for driving the pressing push rod 503 is installed below the pressing base 501, and the cylinder head of the pressing cylinder 504 drives the pressing push rod 503 to move up and down toward the upper side.

[0061] The pressing base 501 is also provided with a pressure sensor 505 and a displacement sensor 506 for detecting the pressing quality. The pressure sensor 505 is fixed above the pressing limit block 502, and the displacement sensor 506 is fixed to the side wall of the pressing base 501. The pressing top rod 503 is connected to a displacement detection block 507, and the pressing top rod 503 drives the displacement detection block 507 to move together.

[0062] Working principle: the product clamp 2 rotates the porcelain tube 14 to the working station of the inner cap pressing device 5 at one end. At this time, there is a certain distance between the upper end face of the porcelain tube 14 and the pressing limit block 502. The cylinder head of the pressing cylinder 504 moves upward, so that the pressing push rod 503 moves upward to lift the porcelain tube 14. The upper end face of the porcelain tube 14 fits with the pressing limit block 502. The pressing cylinder 504 continuously presses upward to do work, so that the inner cap 15 is completely pressed into the lower end face of the porcelain tube 14 to complete the pressing of one end; the pressure sensor 505 obtains the pressing pressure value of the porcelain tube 14, and contacts the displacement detection block 507 through the displacement sensor 506 to obtain the displacement of the pressing of the inner cap 15 on the porcelain tube 14. If the two data reach the set parameter value range, it means that the pressing of the inner cap 15 on the porcelain tube 14 meets the technical requirements.

[0063] like Figure 7As shown, the porcelain tube flipping device 6 includes an adjusting plate 601, on which a moving plate 602 is slidably connected, and the moving plate 602 is moved by a guide rail arranged on the top of the adjusting plate 601. The adjusting plate 601 is also equipped with an adjusting cylinder 603 for driving the moving plate 602 to slide back and forth, and the cylinder head of the adjusting cylinder 603 is horizontally arranged and facing away from the product clamp 2. The moving plate 602 is rotatably connected with a flip clamp 604, and the rotating axis of the flip clamp 604 is horizontally arranged. The moving plate 602 is also equipped with a rotating cylinder 605 for driving the flip clamp 604 to rotate, and the rotating cylinder 605 drives the rotating axis of the flip clamp 604 to rotate through a transmission belt 606.

[0064] Working principle: when the product clamp 2 clamps the porcelain tube 14 and rotates to the porcelain tube flipping device 6 station, the flipping clamp 604 clamps the porcelain tube 14, the cylinder head of the adjustment cylinder 603 extends out, driving the movable plate 602 to move backward, and the rotating cylinder 605 drives the flipping clamp 604 to rotate 180° so that the two ends of the porcelain tube 14 face downward, the cylinder head of the adjustment cylinder 603 retracts, and the movable plate 602 moves forward and resets, and the product clamp 2 clamps the porcelain tube 14 again to complete the flipping action.

[0065] like Figure 8 As shown, the visual inspection device 7 at one end includes a visual inspection support rod 701, which is vertically arranged. A camera 702, a lens 703 and a light source 704 are arranged on the visual inspection support rod 701 from top to bottom to perform CCD visual inspection.

[0066] Working principle: When the product clamp 2 clamps the porcelain tube 14 and rotates to the visual inspection device 7 station at one end, the camera 702 captures and shoots the angle position of the semicircular groove 16 of the inner cap 15 at one end of the porcelain tube 14 vertically downward through the lens. The image acquisition part receives the analog video signal and digitizes it through A / D. The image acquisition part stores the digital image in the memory of the visual processor. The processor processes, analyzes and recognizes the image, and the measurement result is compared with the setting value of the system control interface on the display to measure the angle value of the semicircular groove 16 at the top of the inner cap 15 at one end of the porcelain tube 14. After the inspection is completed, the PLC control system instructs the stepper motor 805 on the inner cap correction device of the next process to rotate an angle to achieve the angle value required by the technical parameters.

[0068] Working principle: When the product clamp 2 clamps the porcelain tube 14 and rotates to the inner cap correction device 8 station at one end, the PLC control system collects information based on the visual inspection device 7 at one end of the upper station. If there is no error in the angle of the groove 16, the step will be skipped. If there is an error in the angle of the groove 16, the lifting cylinder 803 drives the correction clamp 804 to move downward. The correction clamp 804 clamps the porcelain tube 14. After the product clamp 2 is released, the stepper motor 805 drives the porcelain tube 14 to rotate so that the angle of the groove 16 meets the requirements. After the product clamp 2 re-clamps the porcelain tube 14, the correction is completed.

[0072] Working principle: When the inner cap clamp 902 rotates to the two-end inner cap feeding device 903 station, the cylinder head of the clamping cylinder 9034 moves upward, so that the pre-pressure push rod 403 moves to lift the inner cap 15 in the clamping guide rail 9032 to the middle of the inner cap clamp 902, and the inner cap clamp 902 clamps the inner cap 15 to complete the two-end inner cap 15 feeding.

[0073] The structure of the two-end visual inspection device 904 is the same as that of the one-end visual inspection device 7. It measures the angle value of the semicircular groove 16 at the bottom of the two-end inner caps 15. After the inspection is completed, the PLC control system instructs the stepper motor 805 on the next process two-end inner cap correction device 905 to rotate an angle to achieve the angle value required by the technical parameters.

[0074] The correction clamp 804 of the two-end inner cap correction device 905 is located below the two-end inner cap 15, and the rest of the structure is the same as the one-end inner cap correction device 8. The PLC control system adjusts the angle of the groove 16 of the two-end inner cap 15 through the correction clamp 804 according to the information collected by the two-end visual inspection device 904 at the upper workstation, so that the angle of the groove 16 on the two-end inner cap 15 is the same as that on the one-end inner cap 15.

When the two-end visual inspection device 904 detects defective products caused by reasons such as dirt on the inner wall of the inner cap 15 or deformation of the semicircular arc groove 16 at the bottom of the inner wall, the unloading cylinder 9063 drives the unloading rod 9062 to move downward to abut the inner cap 15, thereby opening the inner cap clip 902, so that the defective inner cap falls into the waste box 9064.

[0076] The two-end inner cap preloading device 907 includes a preloading mounting plate 9071, on which two-end inner cap push rods 9072 are movably arranged, and also includes two-end push rod cylinders 9073 for driving the two-end inner cap push rods 9072 to move, the cylinder heads of the two-end push rod cylinders 9073 are directed upward to drive the two-end inner cap push rods 9072 to move up and down, two-end inner cap limit blocks 9074 are arranged above the preloading mounting plate 9071, and one-end inner cap correction rod 9075 and a correction cylinder 9076 for driving one-end inner cap correction rod 9075 are also arranged, the cross-sectional shape of one-end inner cap correction rod 9075 is the same as the shape of the groove 16, and the two-end inner cap limit blocks 9074 are penetrated with correction holes for one-end inner cap correction rod 9075 to pass through.

[0077] Working principle: When the inner cap clamp 902 rotates to the two-end inner cap pre-pressing device 907 station, the product clamp 2 on the main turntable 1 clamps the porcelain tube 14 and rotates to align with the inner cap clamp 902, and the two-end push rod cylinder 9073 drives the two-end inner cap push rod 9072 to move upward, and the two-end inner caps 15 in the inner cap clamp 902 are lifted upward and pressed into the lower end surface of the porcelain tube 14. The inner cap 15 at one end above the porcelain tube 14 fits with the two-end inner cap limit blocks 9074 to complete the pre-pressing of the two-end inner caps 15, and the correction cylinder 9076 drives the inner cap correction rod 9075 at one end to move downward to the groove 16 of the inner cap 15 at one end, which plays a role in re-correcting the positioning.

[0078] The principle of the two-end inner cap pre-pressing mechanism 9 is briefly described as follows: the two-end inner cap loading device 903 conveys the two-end inner caps 15 to the inner cap clamps 902, the two-end visual inspection device 904 detects the angle of the groove 16 on the two-end inner caps 15, and the two-end inner cap correction device 905 rotates the two-end inner caps 15 according to the inspection results to make the angle of the groove 16 of the two-end inner caps 15 meet the requirements. When the two-end inner cap pre-pressing device 907 completes the pre-pressing of the two-end inner caps 15, the angle of the groove 16 of the two-end inner caps 15 is aligned with the angle of the groove 16 of the one-end inner cap 15.

[0079] The structure of the two-end inner cap pressing device 11 is the same as that of the one-end inner cap pressing device 5. After the two-end inner cap pre-pressing mechanism 9 completes pre-pressing, the product clamp 2 clamps the porcelain tube 14 and rotates to the working position of the two-end inner cap pressing device 11 to complete the pressing of the two-end inner caps 15.

[0080] like Fig.14As shown, the length detection device 12 is located between the two-end inner cap pressing device 11 and the finished product unloading mechanism 13, and is used to detect the length of the finished product. The length detection device 12 includes a detection fixed plate 1201, on which a detection sliding plate 1202 is slidably arranged in a vertical direction, and a first cylinder 1203 for driving the detection sliding plate 1202 to move is arranged above the detection fixed plate 1201. The cylinder head of the first cylinder 1203 faces downward to drive the detection sliding plate 1202 to move up and down. An analog proximity switch 1204 is installed on the detection sliding plate 1202, and a length sensing guide rod 1205 is movably arranged below the detection sliding plate 1202, and the bottom of the length sensing guide rod 1205 is an upper top block 1206, and a second cylinder 1208 is arranged below the detection sliding plate 1202, and the cylinder head of the second cylinder 1208 faces upward and is connected to a lower top block 1207.

[0081] Working principle: When the product clamp 2 clamps the porcelain tube 14 and enters the length detection device 12 station, the second cylinder 1208 drives the lower top block 1207 to move upward until the lower top block 1207 fits with the inner cap 15 at the lower end of the porcelain tube 14, and the first cylinder 1203 drives the detection sliding plate 1202 to move downward, so that the upper top block 1206 at the lower end of the length detection sensor approaches the inner cap 15 at the upper end of the porcelain tube 14, and a pressure spring is installed between the upper top block 1206 and the length sensing guide rod 1205. After they are in contact, the length value of the porcelain tube 14 can be obtained by the distance between the analog proximity switch and the upper end face of the length detection sensing guide rod. If the data obtained is within the technical requirements, it is determined that the length value of the porcelain tube 14 is a qualified product.

[0082] like Fig.15 As shown, the unloading mechanism includes a good product unloading device 1301 and a defective product unloading device 1302. The good product unloading device 1301 and the defective product unloading device 1302 are arranged in sequence along the circumference of the main turntable 1. The two have the same structural principle. The good product unloading device 1301 is provided with an unloading clamp and a cylinder for driving the unloading clamp to move. After the unloading clamp clamps the finished product on the product clamp 2, the cylinder drives the unloading clamp to move to the unloading area for unloading.

[0083] The finished product unloading mechanism 13 respectively picks up the good products and the bad products on the product clip 2 through the good product unloading device 1301 and the bad product unloading device 1302 according to the measurement result of the length detection device 12.

[0084] The working process of the utility model is as follows:

[0085] The porcelain tube loading mechanism 3 conveys the porcelain tube 14 to the product clamp 2 in sequence, and the main turntable 1 drives the product clamp 2 to rotate to each workstation in sequence. The inner cap pre-pressing device 4 at one end completes the loading of the inner cap 15 at one end and pre-presses it on the porcelain tube 14. The inner cap pressing device 5 at one end completes the pressing of the inner cap 15 at one end. The visual inspection device 7 at one end and the inner cap correction device 8 at one end detect the angle of the groove 16 of the inner cap 15 at one end and adjust it to correction. The inner cap pre-pressing mechanism 9 at both ends completes the loading, correction and pre-pressing of the inner caps 15 at both ends. The inner cap pressing device 11 at both ends completes the pressing of the inner caps 15 at both ends. The length detection device 12 detects whether the assembled finished product is qualified. Finally, the good products and the defective products are unloaded separately through the finished product unloading mechanism 13 to complete the assembly of the inner caps 15 at both ends of the porcelain tube 14.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
