Description
Technical Field
[0001] The present invention relates to the technical field of medical needle assembly detection, in particular to an automatic assembly detection device for medical needles. Background Art
[0002] As a core component of medical infusion devices, medical needles are primarily used to puncture bottles or bags containing liquid medications and also provide air intake. Medical needles typically consist of a core, air membrane, air intake seat, and protective cap, and require precise assembly under a sterile environment.
[0003] Currently, the industry generally uses manual methods to assemble and test medical needles. However, this method has significant drawbacks. For example, manual assembly and testing are easily affected by the operator's proficiency and fatigue, which can easily lead to problems such as misalignment between the needle core and the air film, uneven air film heat welding temperature, and missed inspections due to visual fatigue. This results in large fluctuations in product assembly quality. Furthermore, manual operation is inefficient, leading to inefficient assembly and testing, which in turn affects the progress of large-scale production. Furthermore, manual assembly can increase the probability of microbial contamination, leading to increased production costs.
[0004] Based on this, there is an urgent need to develop a fully automatic equipment that integrates high-precision assembly and online detection to meet the requirements of large-scale production of medical needles while taking into account both efficiency and quality. Summary of the Invention

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0046] Please refer to Figures 1 to 14 , a medical needle automatic assembly and detection device provided by the present invention, which is applied to a control system. The medical needle automatic assembly and detection device includes a transfer table 101 and a variety of functional components arranged in sequence along the transfer path of the transfer table 101. Specifically, it includes a needle core feeding component 200, an air film feeding component 300, an air film welding component 400, an air film detection component 500, an air inlet seat feeding component 600, a cap feeding component 700, and a blanking component 800. A plurality of load components 110 are arranged at intervals along the transfer path of the transfer table 101. Optionally, the transfer table 101 is rotatably arranged on the workbench 100, and a plurality of load components 110 are arranged at intervals in sequence in the circumferential direction of the rotating transfer table 101, so that the load components 110 can be reused. In addition, the transfer table 101 can also be set to be circular to facilitate the arrangement of each functional component.
[0047] During operation, the needle core feeding component 200, the air film feeding component 300, the air inlet seat feeding component 600, and the cap feeding component 700 sequentially transfer the needle core 121, the air film 122, the air inlet seat 123, and the cap 124 to the corresponding load components 110, and finally assemble them into a complete medical needle. At the same time, since the transfer table 101 also drives other load components 110 to move orderly together, the needle core feeding component 200, the air film feeding component 300, the air inlet seat feeding component 600, and the cap feeding component 700 can synchronously perform their respective assembly operations, improving the assembly efficiency.
[0048] To facilitate loading, the needle core loading assembly 200, the air inlet seat loading assembly 600, and the cap loading assembly 700 all include a vibrating feeding mechanism 210 and a first picking and transferring mechanism 220. Specifically, the vibrating feeding mechanism 210 includes a vibrating disk 211 and a vibrating transmission line 212 provided at the output end of the vibrating disk 211. Through the automatic feeding function and automatic orientation function of the vibrating disk 211, the corresponding assembled parts are quickly and accurately supplied onto the vibrating transmission line 212. It should be noted that the structure and working principle of the vibrating disk 211 can be understood through the prior art and will not be specifically described here. In addition, in order to orderly transfer the corresponding assembled parts, sorting channels 2121 are arranged at intervals on the vibrating transmission line 212, and the first picking and transferring mechanism 220 is provided at the output end of the sorting channel 2121. When the first picking and transferring mechanism 220 works, it sequentially and accurately transfers the assembled parts at the output end of the vibrating transmission line 212 to the carrier assembly 110. It should be noted that in order to prevent the assembled parts from falling off the sorting channel 2121, the shape of the sorting channel 2121 needs to match the external dimension of the assembled parts.
[0049] The air film loading assembly 300 includes a film punching mechanism 310 and a second picking and transferring mechanism 320. Specifically, the film punching mechanism 310 is used to punch the air film sheet to continuously obtain the air film 122 to be assembled. The second picking and transferring mechanism 320 is used to accurately transfer the punched air film 122 to the carrier assembly 110 loaded with the needle core 121, so as to complete the preliminary assembly of the air film 122 and the needle core 121. Then, the carrier assembly 110 carrying the air film 122 and the needle core 121 is moved to the air film welding assembly 400 through the transfer table 101. When the air film welding assembly 400 works, it welds the air film 122 and the needle core 121 together. Then, the carrier assembly 110 loaded with the air film 122 and the needle core 121 is moved to the air film detection assembly 500 through the transfer table 101 for detection. Specifically, the air film detection assembly 500 includes an image detection device 510 and a flow detection device 520. The image detection device 510 is used to detect the welding quality of the air film 122 and the needle core 121, such as detecting whether there are welding defects, and the flow detection device 520 is used to detect the performance of the welded air film 122, such as detecting whether there are airtightness defects.
[0050] The unloading assembly 800 is used to classify and remove the medical needles on the carrier assembly 110. Specifically, it sorts out the qualified medical needles and the unqualified partially assembled assemblies on the corresponding carrier assembly 110.
[0051] To ensure that the assembled parts can be smoothly transported in the sorting channel 2121, in some alternative embodiments, a linear vibration motor (not shown in the drawings) is provided below the sorting channel 2121. By controlling the vibration of the sorting channel 2121, the assembled parts are driven to move forward along the extension path of the sorting channel 2121 until they are transported to the output end of the sorting channel 2121.
[0052] To avoid the feeding speed of the sorting channel 2121 being too slow or lacking materials, resulting in the first picking and transferring mechanism 220 being unable to effectively pick up the needle core 121, the air inlet seat 123, and the cap 124, in some alternative embodiments, as Figure 3 , Figure 9 , Figure 10 shown, a material shortage detector 2122 is provided on the sorting channel 2121. The material shortage detector 2122 can adopt sensing detection devices such as a vision detection system and a photoelectric sensor. During operation, the material shortage detector 2122 sends the detected conveying situation of the needle core 121 in the sorting channel 2121 to the control system, and the control system determines whether there is a material shortage based on the received conveying situation of the needle core 121. When the control system determines a material shortage, it can control the linear vibration motor to increase the feeding speed, for example, by increasing the vibration frequency of the linear vibration motor. In addition, the control system can also trigger an alarm to remind the staff to handle it.
[0053] In some alternative embodiments, as Figure 3 , Figure 10 shown, an air pipe 2123 communicating with an external air supply device is also provided on the sorting channel 2121. When the control system determines a material shortage, the control system can control the opening of the air pipe 2123 to blow air to accelerate the transportation of the assembled parts.
[0054] When the first picking and transferring mechanism 220 fails to pick up the assembled parts in time, to prevent the assembled parts from falling out of the output end of the sorting channel 2121, in some alternative embodiments, as Figure 3 , Figure 9 , Figure 10 shown, a material blocking structure 2124 is provided at the output end of the sorting channel 2121. Among them, the material blocking structure 2124 can be specifically configured according to the structure of the sorting channel 2121 and the structure of the assembled parts.
[0055] In some alternative embodiments, as Figure 2As shown, the carrier assembly 110 is used to limit the needle core 121 in a horizontal state. The carrier assembly 110 includes a mounting block 111, a first pressing block 112, a positioning rod 113, a second pressing block 114, and an elastic member 115. The mounting block 111 is fixedly mounted on the transfer platform 101, and the positioning rod 113 is slidably and vertically penetrated on the mounting block 111. The first pressing block 112 is fixedly connected to the upper end of the positioning rod 113. The second pressing block 114 is located below the mounting block 111 and is fixedly connected to the lower end of the positioning rod 113. The elastic member 115 is limited between the second pressing block 114 and the mounting block 111. When loading the needle core 121 onto the carrier assembly 110, a first lifting mechanism 116 needs to be provided at the corresponding first material picking and transfer mechanism 220. Specifically, when the first lifting mechanism 116 lifts the second pressing block 114 upward, the positioning rod 113 drives the first pressing block 112 to move upward. At this time, a sandwich space is formed between the first pressing block 112 and the mounting block 111. The sandwich space can match the shape of the needle core 121, so that the needle core 121 can be stably placed in the sandwich space. At this time, the elastic member 115 is in a compressed state. When the first lifting mechanism 116 moves downward, the positioning rod 113 drives the first pressing block 112 to move downward together under the action of the restoring force of the elastic member 115. At this time, the sandwich space between the first pressing block 112 and the mounting block 111 is reduced, thereby achieving the purpose of locking the needle core 121. Optionally, the elastic member 115 can be a spring or other device. During assembly, the spring can be sleeved on the positioning rod 113. The first lifting mechanism 116 can be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder, or other devices.
[0056] In some optional embodiments, such as Figure 3 、 Figure 4 As shown, the carrier assembly 110 is used to limit the needle core 121 in a horizontal state, and the sorting channel 2121 on the vibration transmission line 212 for transferring the needle core 121 is used to limit the needle core 121 in a vertical state. The corresponding first material picking and transfer mechanism 220 includes a first machine base 221, a first rotating shaft 222, a relatively arranged limiting frame 223, a first rotating arm 224, a first clamping mechanism 225, and a first translation drive mechanism 226. Specifically, the first rotating shaft 222 is rotatably arranged on the first machine base 221, the limiting frame 223 is arranged on the workbench 100, and a card slot 2231 is provided in the limiting frame 223, and the card slot 2231 extends along the material transfer and conveying direction. The lower end of the first rotating arm 224 is fixedly connected to the first rotating shaft 222, and the upper end of the first rotating arm 224 is rollingly arranged in the card slot 2231. The first clamping mechanism 225 is fixed on the first rotating shaft 222. When the first clamping mechanism 225 is in a clamping state, the first clamping mechanism 225 corresponds to the position of the sorting channel 2121, and the driving end of the first translation drive mechanism 226 is transmission-connected to the first machine base 221.
[0057] In this embodiment, when the first translation driving mechanism 226 is in a working state, the driving end of the first translation driving mechanism 226 drives the first base 221 to horizontally move along the direction of the connection line between the output end of the sorting channel 2121 and the carrying position of the carrying component 110. When the first clamping mechanism 225 is directly above the output end of the sorting channel 2121 and clamps the needle core 121, the first translation driving mechanism 226 moves towards the side of the carrying component 110. At this time, the first base 221 moves towards the side of the carrying component 110, and the upper end of the first rotating arm 224 rolls in the clamping groove 2231, causing the first rotating arm 224 to rotate. Furthermore, the first rotating shaft 222 rotates, so that the first rotating shaft 222 drives the first clamping mechanism 225 to flip until the first clamping mechanism 225 is in a state of horizontally clamping the needle core 121. Then the first translation driving mechanism 226 stops moving. At this time, the needle core 121 just inserts into the clamping space between the first pressing block 112 and the mounting block 111. When the first lifting mechanism 116 moves downward, the clamping space between the first pressing block 112 and the mounting block 111 shrinks, realizing the locking of the needle core 121. Optionally, the first clamping mechanism 225 can be a jaw motor, a jaw cylinder, a jaw hydraulic cylinder, etc.; the first translation driving mechanism 226 can be a telescopic motor, a pen-shaped cylinder, a telescopic hydraulic cylinder, etc. Preferably, the first clamping mechanism 225 is a pen-shaped cylinder. The cylinder body of the pen-shaped cylinder is fixedly installed on the limiting frame 223, and the driving end of the pen-shaped cylinder is fixedly installed on the first base 221.
[0058] In order to make the translation of the first base 221 have better stability, in some alternative embodiments, such as Figure 3 shown, a first sliding plate 2232 is slidably arranged on the limiting frame 223, and the first base 221 is fixedly installed on the first sliding plate 2232. Optionally, a guide rail can be installed on the limiting frame 223, and a slider cooperating with the guide rail is arranged at the bottom of the first sliding plate 2232. At this time, in order to avoid the limiting relationship between the limiting frame 223 and the first sliding plate 2232 from restricting the rotation of the first rotating arm 224, the clamping groove 2231 needs to be set as a stepped clamping groove, that is, there is a height difference between the head and the tail of the stepped clamping groove, and the side close to the sorting channel 2121 has a lower height.
[0059] In order to further make the translation of the first base 221 have better stability, in some alternative embodiments, limiting buffers (not shown in the drawings) are installed on both sides of the first sliding plate 2232 to ensure that the first sliding plate 2232 can stop stably and accurately.
[0060] In some alternative embodiments, such as Figure 5 、 Figure 6As shown, the film punching mechanism 310 includes a conveyor frame 311, a roller-type winding device 312, a punching rod 313, and a first telescopic drive mechanism 314, which are arranged on the conveyor frame 311. The roller-type winding device 312 includes a reel 3121 for winding the air film film and a conveying roller 3122 for conveying the air film film. During operation, the air film 122 on the conveying roller 3122 passes through the active area of the punching rod 313, and the first telescopic drive mechanism 314 is in transmission connection with the punching rod 313. When the first telescopic drive mechanism 314 is in operation, the driving end of the first telescopic drive mechanism 314 drives the punching rod 313 to reciprocate and punch the air film film conveyed on the roller-type winding device 312. Optionally, the first telescopic drive mechanism 314 can be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder, or other devices.
[0061] In some optional embodiments, such as Figure 7 As shown, the loading assembly 110 is used to limit the needle core 121 in a horizontal state, and the second material picking and transporting mechanism 320 includes a first fixed seat 321, a second rotating shaft 322, a rotation drive mechanism 323, a support platform 324, a vacuum suction head 325, and a second translation drive mechanism 326. Specifically, the first fixed seat 321 is fixed on the workbench 100, the second rotating shaft 322 is rotatably arranged on the first fixed seat 321, the rotation drive mechanism 323 is transmission-connected with the second rotating shaft 322, the support platform 324 is arranged on the second rotating shaft 322, the vacuum suction head 325 is slidingly arranged on the support platform 324, the vacuum suction head 325 is used to connect to the external negative pressure generating device, and the suction force generated when in use sucks the air film 122, and when sucking the air film 122, the vacuum suction head 325 corresponds to the position of the punching rod 313, and the second translation drive mechanism 326 is arranged on the support platform 324, and the driving end of the second translation drive mechanism 326 is transmission-connected with the vacuum suction head 325.
[0062] During operation, the driving end of the rotary drive mechanism 323 drives the second rotating shaft 322 to rotate, allowing the vacuum suction head 325 to flip and switch between a vertical state and a horizontal state. The driving end of the second translation drive mechanism 326 drives the vacuum suction head 325 to slide on the support platform 324 to control the lifting and placing of objects. In this way, through the cooperation between the rotary drive mechanism 323 and the second translation drive mechanism 326, the vacuum suction head 325 can change its position and angular posture, completing the operation of the vacuum suction head 325 sucking the air film 122 from the punch rod 313 and placing the picked-up air film 122 on the carrier assembly 110 loaded with the needle core 121. Optionally, the rotary drive mechanism 323 can be a rotary motor, a rotary cylinder, a rotary hydraulic cylinder, etc., and the second translation drive mechanism 326 can be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder, etc.
[0063] In some optional embodiments, such as Figure 7As shown, the vacuum suction head 325 is a telescopic suction head, and a buffer spring 3251 is provided on the vacuum suction head 325. In this way, when the vacuum suction head 325 touches the stamping rod 313, the impact force can be reduced, the picking accuracy of the vacuum suction head 325 can be improved, and when the vacuum suction head 325 contacts the needle core 121 on the load-carrying assembly 110, the impact force can also be reduced, and the placement accuracy of the vacuum suction head 325 can be improved.
[0064] Considering the length of the load-carrying assembly 110 and the stamping efficiency of the stamping rod 313, in some scenarios, the arrangement length of the vacuum suction heads 325 is less than the arrangement length of the stamping rods 313, resulting in the current stamping air film 122 not being able to be completely picked up by the vacuum suction heads 325 at one time. For this reason, in some alternative embodiments, such as Figure 5 , Figure 6 As shown, a stepping drive mechanism 130 is provided on the workbench 100, such as a stepping motor. The conveying frame 311 is arranged on the driving end of the stepping drive mechanism 130. The stepping drive mechanism 130 moves the punching die mechanism 310 laterally by multiple equal distances, realizing multiple pickups of the air film 122 for a single stamping by the second material picking and transferring mechanism 320.
[0065] In some alternative embodiments, such as Figure 8 As shown, the air film welding assembly 400 includes a heat insulation plate 410, a heating rod 420, a welding head 430, and a first vertical drive mechanism 440. The fixed end of the first vertical drive mechanism 440 can be installed on the workbench 100 through a first support seat 450. The heat insulation plate 410 surrounds to form a heat preservation cavity 411, and the heating rod 420 is arranged in the heat preservation cavity 411. The heat insulation plate 410 can effectively prevent the influence of the external environment on the heat preservation cavity 411, so that the temperature fluctuation in the heat preservation cavity 411 is small. The welding head 430 is connected to the heating rod 420, and the driving end of the first vertical drive mechanism 440 is in transmission connection with the heat insulation plate 410. During operation, the heating rod 420 heats the heat preservation cavity 411 until the temperature in the heat preservation cavity 411 rises to a preset temperature. Then, the first vertical drive mechanism 440 drives the heat insulation plate 410 to move downward until the welding head 430 is at the preset welding position. At this time, the high temperature generated by the welding head 430 welds the corresponding parts of the air film 122 and the needle core 121 together. Optionally, the first vertical drive mechanism 440 can be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder and other devices.
[0066] In some alternative embodiments, such as Figure 1 As shown, multiple groups of air film welding assemblies 400 are arranged in sequence along the transmission path of the transmission table 101 to improve the welding efficiency.
[0067] In some alternative embodiments, such as Figure 8As shown, the heat insulation plate 410 is slidably arranged on the first support seat 450 to improve the stability of the up-and-down movement of the heat insulation plate 410.
[0068] In some alternative embodiments, such as Figure 8 As shown, a limit adjustment column 460 is arranged on the movement path of the heat insulation plate 410. The limit adjustment column 460 can prevent the first vertical driving mechanism 440 from driving the heat insulation plate 410 beyond the preset welding position, so that the needle core 121, the carrier assembly 110, and the air film welding assembly 400 are not easily damaged due to collision. Optionally, the limit adjustment column 460 is arranged on the first support seat 450 or can be directly arranged on the workbench 100.
[0069] In some alternative embodiments, the limit adjustment column 460 includes a stopper and a screw rod. The screw rod can be arranged on the first support seat 450 or can be directly arranged on the workbench 100. The stopper is fixedly installed on the heat insulation plate 410, and the contact height between the stopper and the screw rod is adjusted by adjusting the screwing depth of the screw rod.
[0070] In some alternative embodiments, such as Figure 8 As shown, the air film welding assembly 400 further includes an anti-tilting lifting mechanism 470, and the anti-tilting lifting mechanism 470 is arranged on the workbench 100. When the welding head 430 performs welding, a downward force will be applied, which may cause the transfer table 101 to tilt, which is not conducive to precise assembly and welding. At this time, the transfer table 101 is lifted and pushed upward by the anti-tilting lifting mechanism 470 to prevent the transfer table 101 from tilting. Optionally, the anti-tilting lifting mechanism 470 can be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder or other devices.
[0071] In some alternative embodiments, such as Figure 9As shown, the load-carrying assembly 110 is provided with a plurality of load-carrying positions arranged side by side, so that a plurality of assembled parts can be carried, improving the assembly efficiency. The image detection device 510 includes a third translation driving mechanism 511, an image sensor 512, a position sensor 513, and a plurality of induction trigger members 514. Specifically, the moving direction of the driving end of the third translation driving mechanism 511 is parallel to the arrangement direction of the load-carrying positions on the load-carrying assembly 110. The image sensor 512 is arranged on the driving end of the third translation driving mechanism 511, the position sensor 513 is arranged on the image sensor, and the plurality of induction trigger members 514 are arranged at intervals along the moving direction of the driving end of the third translation driving mechanism 511. The positions of the respective induction trigger members 514 correspond one-to-one to the respective load-carrying positions on the load-carrying assembly 110. Optionally, the image sensor 512 can be an image acquisition device such as a CCD camera or a CMOS camera. The position sensor 513 and the induction trigger member 514 can be a photoelectric switch assembly, and a combination of a magnetic sensor and a magnetic marking member can also be selected, or a combination of a capacitive sensor and a metal induction sheet can be selected. The third translation driving mechanism 511 can be a device such as a telescopic motor, a telescopic cylinder, or a telescopic hydraulic cylinder.
[0072] In this embodiment, when the third translation driving mechanism 511 is in a working state, the driving end of the third translation driving mechanism 511 drives the image sensor 512 to move, so that the image sensor 512 can sequentially collect each assembled part on the load-carrying assembly 110. Moreover, when the image sensor 512 moves to the position of a certain assembled part for shooting, the position sensor 513 on the image sensor 512 is aligned with the induction trigger member 514. At this time, the position sensor 513 generates a trigger signal, and the control system controls the third translation driving mechanism 511 to stop moving the image sensor 512 according to this trigger signal, ensuring the alignment accuracy between the image sensor 512 and the assembled parts on the load-carrying assembly 110. After completing a single detection, it moves to the next detection position. After the air film 122 and the needle core 121 are assembled together, a welding line will be formed in a circle on the surface of the needle core 121 by the welded air film 122. At this time, image acquisition is performed through the image sensor 512, and the control system compares the image data collected by the image sensor 512 with the welding line of the qualified product to determine whether the welding is qualified.
[0073] In some alternative embodiments, such as Figure 10As shown in the figure, the flow rate detection device 520 includes a second vertical driving mechanism 521, a ventilation pipe 522, a ventilation head 523, a spring 524, and a flow meter 525. Specifically, the fixed end of the second vertical driving mechanism 521 can be installed on the workbench 100 through a second support base 526. The moving direction of the driving end of the second vertical driving mechanism 521 intersects with the arrangement direction of the bearing positions on the load-carrying assembly 110. One end of the ventilation pipe 522 is fixed to the driving end of the second vertical driving mechanism 521. The ventilation head 523 is slidably arranged at the other end of the ventilation pipe 522. The ventilation head 523 communicates with the ventilation pipe 522. The spring 524 is sleeved on the ventilation pipe 522 and is arranged between the ventilation head 523 and the driving end of the second vertical driving mechanism 521. The output end of the flow meter 525 communicates with the intake end of the ventilation pipe 522. The input end of the flow meter 525 is used to connect to the gas delivery device. Optionally, the second vertical driving mechanism 521 can be selected from devices such as a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder, etc.
[0074] In this embodiment, when the second vertical driving mechanism 521 is in the working state, the driving end of the second vertical driving mechanism 521 drives the ventilation pipe 522 to move downward until the ventilation head 523 is inserted into the corresponding position of the needle core 121 on the load-carrying assembly 110. During the insertion process, the ventilation head 523 slides upward relative to the lower end of the ventilation pipe 522, causing the spring 524 to be compressed. The spring 524 generates a downward thrust, causing the ventilation head 523 to be tightly inserted into the corresponding position of the needle core 121 on the load-carrying assembly 110, thereby forming a good seal. Then, the gas delivery device is turned on, and the output gas passes through the flow meter 525 and the ventilation pipe 522 in sequence, and finally is output from the ventilation head 523. The gas delivery device can precisely adjust the intake pressure by setting a precision pressure regulating valve 527, thereby achieving the intake pressure required for detection. When abnormal situations such as film breakage occur in the air film 122, the gas flow rate of the flow meter 525 will change, thereby determining whether there are airtightness defects in the air film 122.
[0075] Through the combined detection of the image detection device 510 and the flow rate detection device 520, the positions of qualified products and unqualified products can be recorded, which is convenient for the control system to determine whether to assemble the remaining assembly parts, thereby reducing the waste of subsequent assembly parts.
[0076] In some alternative embodiments, such as Figure 11As shown, the load-carrying component 110 is used to limit the needle core 121 in a horizontal state, and the sorting channel 2121 on the vibration transmission line 212 of the transfer intake seat 123 is used to limit the intake seat 123 in a vertical state. The corresponding first material-taking and transferring mechanism 220 includes a second fixed seat 231, a fourth translation driving mechanism 232, a third vertical driving mechanism 233, a material-taking head 234, and a second telescopic driving mechanism 235. Specifically, the fixed end of the fourth translation driving mechanism 232 is arranged on the second fixed seat 231, the second fixed seat 231 is fixedly installed on the workbench 100, the fixed end of the third vertical driving mechanism 233 is arranged on the driving end of the fourth translation driving mechanism 232, the material-taking head 234 is arranged on the driving end of the third vertical driving mechanism 233, and the middle of the material-taking head 234 is hollow. In order to ensure that the material-taking head 234 can clamp the intake seat 123, the clamping position of the material-taking head 234 and the intake seat 123 is in interference fit. The fixed end of the second telescopic driving mechanism 235 is arranged on the driving end of the third vertical driving mechanism 233, and the telescopic end of the second telescopic driving mechanism 235 can shuttle through the hollow part in the middle of the material-taking head 234. Optionally, the fourth translation driving mechanism 232, the third vertical driving mechanism 233, and the second telescopic driving mechanism 235 can all be selected from devices such as telescopic motors, telescopic cylinders, and telescopic hydraulic cylinders. Preferably, both the fourth translation driving mechanism 232 and the third vertical driving mechanism 233 are selected as pen-shaped cylinders.
[0077] In this embodiment, when the third vertical driving mechanism 233 is in the working state, the driving end of the third vertical driving mechanism 233 drives the material-taking head 234 to move downward until the material-taking head 234 is inserted into the clamping position of the intake seat 123 on the sorting channel 2121. Then, the driving end of the third vertical driving mechanism 233 drives the material-taking head 234 to move upward, and the driving end of the fourth translation driving mechanism 232 then drives the entire third vertical driving mechanism 233 to move toward the load-carrying component 110 side until the intake seat 123 clamped on the material-taking head 234 is aligned with the corresponding position of the assembled part on the load-carrying component 110. Then, the driving end of the third vertical driving mechanism 233 drives the material-taking head 234 to move downward until the material-taking head 234 is inserted into the corresponding position of the assembled part on the load-carrying component 110. Finally, the telescopic end of the second telescopic driving mechanism 235 extends to eject the intake seat 123 from the material-taking head 234. When it is necessary to pick up the remaining intake seats 123 on the sorting channel 2121, first, the telescopic end of the second telescopic driving mechanism 235 contracts, then the driving end of the third vertical driving mechanism 233 drives the material-taking head 234 to move upward, then the driving end of the fourth translation driving mechanism 232 drives the entire third vertical driving mechanism 233 to move toward the sorting channel 2121 side, and finally, the driving end of the third vertical driving mechanism 233 drives the material-taking head 234 to move downward.
[0078] In order to make the translation of the driving end of the fourth translation driving mechanism 232 have better smoothness, in some alternative embodiments, such as Figure 11 As shown, a second sliding plate 236 is slidably provided on the second fixed seat 231, and the fixed end of the third vertical driving mechanism 233 is fixedly installed on the second sliding plate 236. Optionally, a guide rail can be installed on the second fixed seat 231, and a slider cooperating with the guide rail is provided at the bottom of the second sliding plate 236.
[0079] In order to further make the translation of the driving end of the fourth translation driving mechanism 232 have better smoothness, in some alternative embodiments, limiting buffers are installed on both sides of the second sliding plate 236 to ensure that the second sliding plate 236 can stop stably and accurately.
[0080] In some alternative embodiments, such as Figure 12 As shown, the load-carrying assembly 110 is used to limit the needle core 121 in a horizontal state, and the sorting channel 2121 on the vibration transmission line 212 of the transfer cap 124 is used to limit the cap 124 in a vertical state. The corresponding first material-taking and transferring mechanism 220 includes a third fixed seat 241, a fifth translation driving mechanism 242, a third rotating shaft 243, a second clamping mechanism 244, a second rotating arm 245, a third telescopic driving mechanism 246, and a fourth telescopic driving mechanism 247. Specifically, the third fixed seat 241 is fixedly installed on the workbench 100, the fixed end of the fifth translation driving mechanism 242 is provided on the third fixed seat 241, the third rotating shaft 243 is rotatably provided on the driving end of the fifth translation driving mechanism 242, the second clamping mechanism 244 is fixedly provided on the third rotating shaft 243. When the second clamping mechanism 244 is in a clamping state, the position of the second clamping mechanism 244 corresponds to that of the sorting channel 2121. The upper end of the second rotating arm 245 is fixedly connected to the third rotating shaft 243, the fixed end of the third telescopic driving mechanism 246 is provided on the driving end of the fifth translation driving mechanism 242, the telescopic end of the third telescopic driving mechanism 246 is rotatably connected to the lower end of the second rotating arm 245, the fixed end of the fourth telescopic driving mechanism 247 is provided on the third fixed seat 241, and the telescopic end of the fourth telescopic driving mechanism 247 is set to be unloaded and the telescopic direction is parallel to the placing direction of the needle core 121 on the load-carrying assembly 110.
[0081] In this embodiment, when the fifth translation driving mechanism 242 is in the working state, the driving end of the fifth translation driving mechanism 242 moves horizontally along the connecting line direction between the output end of the sorting channel 2121 and the carrying position of the carrying component 110. When the third telescopic driving mechanism 246 is in the working state, the telescopic end of the third telescopic driving mechanism 246 drives the second rotating arm 245 to rotate, and then drives the third rotating shaft 243 to rotate, so that the second clamping mechanism 244 is directly above the output end of the sorting channel 2121 and picks up the protective cap 124 on the sorting channel 2121. Then, the telescopic end of the third telescopic driving mechanism 246 drives the second rotating arm 245 to rotate in the reverse direction, and then drives the third rotating shaft 243 to rotate in the reverse direction, so that the second clamping mechanism 244 horizontally clamps the protective cap 124. Then, the fifth translation driving mechanism 242 moves toward the side of the carrying component 110. At this time, the second clamping mechanism 244 horizontally clamps the protective cap 124 and moves toward the side of the carrying component 110. Until the protective cap 124 horizontally clamped by the second clamping mechanism 244 is aligned with the position of the needle core 121 on the carrying component 110, the telescopic end of the fourth telescopic driving mechanism 247 quickly retracts, and the protective cap 124 is sleeved on the needle core 121 through inertia force. Optionally, the second clamping mechanism 244 can be a jaw motor, a jaw cylinder, a jaw hydraulic cylinder and other devices; the fifth translation driving mechanism 242 can be a telescopic motor, a pen-shaped cylinder, a telescopic hydraulic cylinder and other devices, and both the third telescopic driving mechanism 246 and the fourth telescopic driving mechanism 247 can be telescopic motors, telescopic cylinders, telescopic hydraulic cylinders and other devices. It should be noted that, in order to provide appropriate inertia force, the fourth telescopic driving mechanism 247 needs to select a model with appropriate thrust according to the actual situation.
[0082] It should also be noted that when the image detection device 510 and the flow detection device 520 jointly detect and record the positions of qualified products and unqualified products, the second clamping mechanism 244 can be controlled not to clamp the protective cap 124 at the corresponding position for assembly, so as to avoid assembling the protective cap 124 onto unqualified products.
[0083] In some alternative embodiments, such as Figure 12 shown, a push plate 2431 is provided on the third rotating shaft 243, and the push plate 2431 can push the protective cap 124 tightly to prevent the protective cap 124 from falling off the second clamping mechanism 244.
[0084] In some alternative embodiments, such as Figure 12 shown, the fixed end of the third telescopic driving mechanism 246 is rotatably connected to the driving end of the fifth translation driving mechanism 242, so that the fixed end of the third telescopic driving mechanism 246 can rotate to prevent the second rotating arm 245 from getting stuck during rotation.
[0085] In some optional embodiments, a limit buffer is provided on the fixed end of the third telescopic drive mechanism 246, which can ensure that the third rotating shaft 243 can stop stably and accurately, thereby achieving the effect of accurately adjusting the rotation angle of the third rotating shaft 243 and reducing the vibration caused by the rapid stopping of the third rotating shaft 243.
[0086] In order to make the translation of the driving end of the fifth translation driving mechanism 242 have better stability, in some optional embodiments, such as Figure 12 As shown, a third sliding plate 248 is slidably mounted on the third fixed seat 241, a driving end of the fifth translation drive mechanism 242 is fixedly connected to the third sliding plate 248, and the third rotating shaft 243 is rotatably mounted on the third sliding plate 248. Optionally, a guide rail may be mounted on the third fixed seat 241, and a slider that cooperates with the guide rail may be disposed at the bottom of the third sliding plate 248.
[0087] In order to further ensure better stability in the translation of the driving end of the fifth translation drive mechanism 242, in some optional embodiments, limit buffers are installed on both sides of the third sliding plate 248 to ensure that the third sliding plate 248 can stop stably and accurately.
[0088] In some optional embodiments, such as Figure 1 As shown, the blanking assembly 800 includes a qualified product blanking assembly 810 and a rejected product blanking assembly 820 which are sequentially arranged along the transmission path of the transmission platform 101 .
[0089] Specifically, if Figure 13 As shown, the qualified product unloading assembly 810 includes a fourth vertical drive mechanism 811 and a sixth translation drive mechanism 812 that operate sequentially. The total number of the fourth vertical drive mechanism 811 and the sixth translation drive mechanism 812 is consistent with the number of needle cores 121 placed on the carrier assembly 110. The fixed end of the fourth vertical drive mechanism 811 is fixedly mounted on the workbench 100. During operation, the driving end of the fourth vertical drive mechanism 811 pushes the second clamping block 114 upward, and the positioning rod 113 drives the first clamping block 112 to move upward. At this time, the sandwiched space formed between the first clamping block 112 and the mounting block 111 expands, releasing the pressure on the needle core 121. At this time, the driving end of the sixth translation drive mechanism 812 pushes the needle core 121 horizontally, thereby removing the corresponding needle core 121 from the carrier assembly 110. The control system can control the sixth translation drive mechanism 812 to push out the qualified products on the carrier assembly 110, but not to push out the unqualified products on the carrier assembly 110. The qualified products finally assembled are as follows: Figure 15As shown. The carrier assembly 110 loaded with defective products then moves via the transfer platform 101 to the defective product unloading assembly 820. Optionally, the fourth vertical drive mechanism 811 and the sixth translation drive mechanism 812 can both utilize a telescopic motor, a pen-shaped cylinder, a telescopic hydraulic cylinder, or the like. Preferably, both the fourth vertical drive mechanism 811 and the sixth translation drive mechanism 812 utilize a pen-shaped cylinder.
[0090] like Figure 14 As shown, the defective product unloading assembly 820 includes a set of fifth vertical drive mechanisms 821 and a set of seventh translation drive mechanisms 822 that work in sequence. The fixed end of the fifth vertical drive mechanism 821 is fixedly mounted on the workbench 100, and the fixed end of the seventh translation drive mechanism 822 is fixedly mounted on the transfer platform 101. During operation, the driving end of the fifth vertical drive mechanism 821 lifts the second clamping block 114 upward, and the positioning rod 113 drives the first clamping block 112 to move upward. At this time, the sandwiched space formed between the first clamping block 112 and the mounting block 111 expands, and the needle core 121 is not compressed. At this time, the driving end of the seventh translation drive mechanism 822 pushes the needle core 121 horizontally, thereby removing the corresponding needle core 121 on the carrier assembly 110, thereby collecting the defective products. Optionally, the fifth vertical drive mechanism 821 and the seventh translation drive mechanism 822 can both use telescopic motors, telescopic cylinders, telescopic pressure cylinders and other devices. The telescopic end of the seventh translation drive mechanism 822 is installed with multiple ejection rods 8221, so that the seventh translation drive mechanism 822 can eject all defective products on the carrier component 110 with one extension and contraction.
[0091] In order to facilitate the collection of qualified products ejected by the sixth translation drive mechanism 812, in some optional embodiments, such as Figure 13 As shown, the qualified product unloading assembly 810 also includes a guide plate 813, which is installed on the workbench 100. The guide plate 813 guides the qualified products to a predetermined collection device. To prevent the installation position of the guide plate 813 from interfering with the position of the sixth translation drive mechanism 812, the fixed end of the sixth translation drive mechanism 812 is fixedly mounted on the transfer platform 101.
