Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] In order to solve the problems in the background art that existing automated assembly equipment often can only complete the assembly of a single process, lacks the function of on-line detection of the performance of the assembled nozzle, cannot screen out unqualified products in time, resulting in low production efficiency and increased rework costs, and during the production process of the nozzle, a protective cover needs to be installed for protection, and most existing assembly equipment cannot detect the connection tightness between the protective cover and the nozzle, and cannot timely discover assembly defects during the production process, please refer to Figures 1-9, A multi-component precise positioning and assembly device for a drug nozzle, including a chassis 100. The bottom wall of the inner cavity of the chassis 100 is fixedly connected with a first motor 110. The transmission end of the first motor 110 is fixedly connected with a first rotating rod 120. The upper side of the first rotating rod 120 is fixedly connected with a support plate 130. The outer side of the support plate 130 is fixedly connected with the inner wall of the chassis 100. A plurality of vibration plates 200 are evenly and fixedly arranged on the outer side of the chassis 100. One side of the vibration plate 200 close to the chassis 100 is fixedly connected with a feeding box 210. A blanking device 400 is fixedly arranged on the left side of the chassis 100. A plurality of feeding devices 500 are evenly arranged on the upper side of the chassis 100. During use, start the first motor 110. Drive the first rotating rod 120 to rotate through the first motor 110. Drive the support plate 130 to rotate through the rotation of the first rotating rod 120. Drive the auxiliary device 300 to rotate through the rotation of the support plate 130. During use, the vibration plate 200 arranges and feeds the goods into the feeding box 210. Then the workpieces in the feeding box 210 are fed into the interior of the front auxiliary device 300 through the feeding device 500. Subsequently, the auxiliary device 300 is rotated by the support plate 130 and fed into the next feeding device 500. Then continue the assembly through the next feeding device 500.

[0038] A plurality of auxiliary devices 300 are uniformly and fixedly arranged on the outer side of the support plate 130. The auxiliary device 300 includes a fixed pipe 310 and a movable pipe 330. A first annular groove 311 is formed in the inner wall of the fixed pipe 310. Two first lifting grooves 312 are formed in the inner wall of the fixed pipe 310. Two second annular grooves 313 are formed in the inner wall of the fixed pipe 310. A rotating pipe 340 is arranged on the upper side of the fixed pipe 310. Guide blocks 341 are fixedly connected to both the left and right sides of the rotating pipe 340. A rotating and lifting device is arranged on the lower side of the fixed pipe 310. The rotating and lifting device includes a second cylinder 320 and a movable pipe 330. The side of the limiting block 332 close to the movable rod 350 is arc-shaped. By arranging the side of the limiting block 332 close to the movable rod 350 to be arc-shaped, the friction between the limiting block 332 and the movable pipe 330 can be effectively reduced, making the movement between the limiting block 332 and the movable rod 350 smoother and improving the stability of the lifting of the movable pipe 330. The second cylinder 320 is installed on the upper side of the support plate 130. The movable pipe 330 is located inside the fixed pipe 310. The telescopic end of the second cylinder 320 is fixedly connected to the movable pipe 330. A movable rod 350 is arranged inside the movable pipe 330. The upper side of the movable rod 350 is fixedly connected to the rotating pipe 340. The movable pipe 330 is not connected to the rotating pipe 340. A limiting block 332 is fixedly connected to the left side of the movable pipe 330. A limiting groove matching the limiting block 332 is formed in the outer wall of the movable rod 350. First connecting plates 331 are fixedly connected to both the front and rear sides of the movable pipe 330. Sliding grooves matching the first connecting plates 331 are formed in both the front and rear sides of the fixed pipe 310. The telescopic end of the second cylinder 320 is fixedly connected to the rear first connecting plate 331. When the nozzle is generally assembled, the second cylinder 320 is started. The second cylinder 320 drives the movable pipe 330 to move upward. During the upward movement of the movable pipe 330, the rotating pipe 340 and the movable rod 350 are driven to move upward. At this time, the rotating pipe 340 drives the guide block 341 to move upward in the first lifting groove 312 until the guide block 341 enters the first annular groove 311. Then the guide block 341 is limited and cannot rise. At this time, the movable pipe 330 continues to move upward, driving the limiting block 332 to squeeze the movable rod 350, and the movable rod 350 cannot move either. Therefore, the limiting block 332 slides in the limiting groove of the movable rod 350, thereby squeezing the movable rod 350 and causing the movable rod 350 to rotate. Then the movable rod 350 drives the rotating pipe 340 to rotate. The rotating pipe 340 rotates 180° or 360° as required and then waits for the descending operation. When descending, the movable pipe 330 descends, driving the limiting block 332 to descend, and then driving the movable rod 350 and the rotating pipe 340 to descend until the guide block 341 located in the first lifting groove 312 enters the second annular groove 313. Subsequently, the movable pipe 330 continues to drive the limiting block 332 to descend. The rotating pipe 340 is limited by the guide block 341 and cannot descend, resulting in the movable rod 350 being unable to descend. Thus, the guide block 341 slides in the limiting groove of the movable rod 350.The guide block 341 squeezes the moving rod 350, causing the moving rod 350 to rotate and drive the rotating pipe 340 to rotate. When the rotating pipe 340 needs to descend, the second cylinder 320 is activated to drive the moving pipe 330, the moving rod 350, and the rotating pipe 340 to descend. The rotating pipe 340 drives the nozzle body to rise, then contacts the baffle 600 and is limited by the baffle 600. Then, the baffle 600 squeezes the upper side of the nozzle body, driving the nozzle body to move downward to test whether the spring in the nozzle body can be used normally. Then, the rotating pipe 340 rotates to drive the nozzle body to rotate. During this process, the shape detector 610 detects the shape of the nozzle body. After the detection, the auxiliary device 300 can also drive the nozzle to move downward and rotate again to detect the shape of the nozzle body again. For the nozzles that have been detected twice, the quality control is more strict and stable. Then, the unqualified nozzles are diverted through the feeding device 500. When the nozzle body is assembled, the next feeding device 500 assembles the upper protective cover of the nozzle body. During this process, the rotating pipe 340 drives the nozzle body to rise, and then the nozzle body rotates after rising, causing the nozzle body to rotate after entering the protective cover, so that the nozzle body is connected to the protective cover. At the same time, rotating in the reverse direction after the nozzle descends can also detect the connection tightness between the nozzle and the protective cover, improving the production efficiency and quality of the nozzles of this device. By setting the auxiliary device 300, the assembled nozzle components can be driven to rotate and lift, so that the nozzle body can test whether the spring in the nozzle body can be used normally. During this process, the nozzle body can also be rotated to drive the nozzle body to rotate, so that the shape detector 610 can perform cyclic multi-angle detection on the shape of the nozzle body, effectively improving the production efficiency and quality of the nozzles. At the same time, the feeding device 500 assists in the screw connection assembly of the upper protective cover of the nozzle body.,

[0039] The feeding device 500 includes a first linear guide rail 510, which is fixedly installed on the lower side of the upper side wall of the chassis 100. The moving end of the first linear guide rail 510 is fixedly connected with a first cylinder 520, and the telescopic end of the first cylinder 520 is connected with a clamp 530. By activating the first linear guide rail 510, the clamp 530 is driven to move back and forth through the first linear guide rail 510, and the clamp 530 is driven to move up and down through the first cylinder 520. By setting the feeding device 500, the workpieces removed from the vibrating disk 200 can be moved to cooperate with the auxiliary device 300 for the assembly work of the nozzles.,

[0040] The blanking device 400 includes a first blanking slide plate 410. Two groups of second blanking slide plates 420 are fixedly connected to the left side of the first blanking slide plate 410. A first guiding plate 430 is movably installed on the upper side of the first blanking slide plate 410. A third air cylinder 450 is fixedly connected to the upper side of the first blanking slide plate 410. The telescopic end of the third air cylinder 450 is movably connected to the first guiding plate 430. During use, the third air cylinder 450 is started, and the first guiding plate 430 is driven by the third air cylinder 450 to adjust the angle, so as to guide the workpieces falling from the first blanking slide plate 410, so that the unqualified workpieces enter the second blanking slide plate 420 at the front side, and the qualified workpieces enter the second blanking slide plate 420 at the rear side. By setting the blanking device 400, the nozzle body can be guided, so that the qualified nozzle body and the unqualified nozzles enter different second blanking slide plates 420 for collection work, improving the practicability and convenience of the use of this device. A first connecting rod 440 is fixedly connected to the upper side of the first guiding plate 430. The telescopic end of the third air cylinder 450 is fixedly connected to a second connecting plate 460. A chute is opened on the body of the second connecting plate 460. The first connecting rod 440 is located in the chute of the second connecting plate 460. The third air cylinder 450 is started, and the second connecting plate 460 is driven by the third air cylinder 450 to move back and forth. The first connecting rod 440 is driven to move back and forth by the back-and-forth movement of the second connecting plate 460. The first guiding plate 430 is driven to perform the angle adjustment work by the back-and-forth movement of the first connecting rod 440. By setting the second connecting plate 460 and the first connecting rod 440, the running stability of the blanking device 400 can be effectively improved, and the practicability of the use of this device is improved.

By setting the baffle 600 and the outer shape detector 610, the spring test and outer shape detection work of the nozzle can be effectively cooperated with the auxiliary device 300, improving the production efficiency and quality of this device.
