Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art 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.

[0021] Please refer to Figures 1 to 14 , is 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 transmission platform 101, and a plurality of functional components arranged in sequence along the transmission path of the transmission platform 101, specifically including a needle core loading component 200, an air film loading component 300, an air film welding component 400, an air film detection component 500, an air inlet seat loading component 600, a protective cap loading component 700, and a unloading component 800. The transmission platform 101 is provided with a plurality of carrier components 110 at intervals along its transmission path. Optionally, the transmission platform 101 is rotatably arranged on the workbench 100, and a plurality of carrier components 110 are arranged in sequence at intervals in the circumference of the rotating transmission platform 101, so that the carrier components 110 can be reused. In addition, the transmission platform 101 can also be set to a circular shape to facilitate the arrangement of various functional components.

[0022] During operation, the needle core loading assembly 200, the air membrane loading assembly 300, the air inlet seat loading assembly 600 and the protective cap loading assembly 700 transfer the needle core 121, the air membrane 122, the air inlet seat 123 and the protective cap 124 to the corresponding carrier assembly 110 in turn, and finally assemble them into a complete medical needle. At the same time, since the transmission platform 101 also drives other carrier assemblies 110 to move in an orderly manner, the needle core loading assembly 200, the air membrane loading assembly 300, the air inlet seat loading assembly 600 and the protective cap loading assembly 700 can perform their respective assembly operations simultaneously, thereby improving the assembly efficiency.

[0023] In order to facilitate loading, the needle core loading assembly 200, the air intake seat loading assembly 600 and the protective cap loading assembly 700 all include a vibration feeding mechanism 210 and a first material picking and transferring mechanism 220. Specifically, the vibration feeding mechanism 210 includes a vibration disk 211 and a vibration transmission line 212 arranged at the output end of the vibration disk 211. Through the automatic feeding function and automatic orientation function of the vibration disk 211, the corresponding assembly parts are quickly and accurately supplied to the vibration transmission line 212. It should be noted that the structure and working principle of the vibration disk 211 can be understood through the existing technology and will not be described in detail here. In addition, in order to orderly transmit the corresponding assembly parts, sorting channels 2121 are arranged at intervals on the vibration transmission line 212, and the first material picking and transferring mechanism 220 is arranged at the output end of the sorting channel 2121. When the first material picking and transferring mechanism 220 is working, the assembly parts at the output end of the vibration transmission line 212 are accurately transferred to the carrier component 110 in sequence. It should be noted that in order to prevent the assembly parts from falling off from the sorting channel 2121, the shape of the sorting channel 2121 needs to match the outer dimensions of the assembly parts.

[0024] The air film loading assembly 300 includes a film punching mechanism 310 and a second material picking and transporting mechanism 320. Specifically, the film punching mechanism 310 is used to punch the air film film sheet, so as to continuously obtain the air film 122 to be assembled. The second material picking and transporting 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, and 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 transmission platform 101. When the air film welding assembly 400 is working, the air film 122 and the needle core 121 are welded together, and 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 transmission platform 101 for detection. Specifically, the air film detection component 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. The flow detection device 520 is used to detect the performance of the air film 122 after welding, such as detecting whether there are airtightness defects.

[0025] The unloading component 800 is used to classify and remove the medical needles on the carrier component 110, specifically, to sort out the qualified medical needles and the unqualified partially assembled assemblies on the corresponding carrier component 110.

[0026] In order to ensure that the assembled parts can be smoothly transported in the sorting channel 2121, in some optional embodiments, a linear vibration motor (not shown in the drawings) is arranged below the sorting channel 2121, and the vibration of the sorting channel 2121 is controlled to drive the assembled parts along the extension path of the sorting channel 2121 until they are transported to the output end of the sorting channel 2121.

[0027] In order to prevent the sorting channel 2121 from feeding too slowly or lacking materials, resulting in the first material transfer mechanism 220 being unable to effectively pick up the needle core 121, the air inlet seat 123 and the protective cap 124, in some optional embodiments, such as Figure 3 , Fig. 9 , Fig.10 As shown, a material shortage detector 2122 is provided on the sorting channel 2121, and the material shortage detector 2122 can adopt a sensor detection device such as a visual detection system and a photoelectric sensor. When working, the material shortage detector 2122 sends the collected conveying conditions 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 conditions of the needle core 121. When the control system determines that there is a material shortage, the linear vibration motor can be controlled 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.

[0028] In some optional embodiments, such as Figure 3 , Fig.10 As shown, an air pipe 2123 connected to an external air supply device is also provided on the sorting channel 2121. When the control system determines that there is a shortage of material, the control system can control the opening of the air pipe 2123 for blowing to accelerate the delivery of assembled parts.

[0029] When the first material transfer mechanism 220 fails to pick up the assembly parts in time, in order to prevent the assembly parts from falling out from the output end of the sorting channel 2121, in some optional embodiments, such as Figure 3 , Fig. 9 , Fig.10 As shown, a material blocking structure 2124 is provided at the output end of the sorting channel 2121. 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.

[0030] In some optional embodiments, such 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 clamping block 112, a positioning rod 113, a second clamping block 114, and an elastic member 115. The mounting block 111 is fixedly mounted on the transmission platform 101, and the positioning rod 113 is slidably and vertically penetrated on the mounting block 111. The first clamping block 112 is fixedly connected to the upper end of the positioning rod 113, and the second clamping block 114 is located below the mounting block 111 and fixedly connected to the lower end of the positioning rod 113. The elastic member 115 is limited between the second clamping 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 clamping block 114 upward, the positioning rod 113 drives the first clamping block 112 to move upward, and a sandwich space is formed between the first clamping 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, and the elastic member 115 is in a compressed state; when the first lifting mechanism 116 moves downward, the positioning rod 113 drives the first clamping block 112 to move downward together under the restoring force of the elastic member 115, and the sandwich space between the first clamping 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, and the spring can be sleeved on the positioning rod 113 during assembly, and the first lifting mechanism 116 can be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder or other devices.

[0031] 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 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 is extended 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 fixedly arranged 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 driving mechanism 226 is transmission connected to the first machine base 221.

[0032] In this embodiment, when the first translation driving mechanism 226 is in working state, the driving end of the first translation driving mechanism 226 drives the first base 221 to move horizontally along the line connecting the output end of the sorting channel 2121 and the carrying position of the object 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 drive mechanism 226 moves toward the side of the carrier assembly 110. At this time, the first machine base 221 moves toward the side of the carrier assembly 110, and the upper end of the first rotating arm 224 rolls in the slot 2231, so that the first rotating arm 224 rotates, and then the first rotating shaft 222 rotates, so that the first rotating shaft 222 will drive the first clamping mechanism 225 to flip until the first clamping mechanism 225 is in a state of horizontally clamping the needle core 121, and the first translation drive mechanism 226 stops moving. At this time, the needle core 121 is just inserted into the clamping space between the first clamping block 112 and the mounting block 111. When the first lifting mechanism 116 moves downward, the clamping space between the first clamping block 112 and the mounting block 111 is reduced, thereby locking the needle core 121. Optionally, the first clamping mechanism 225 can use a clamping motor, a clamping cylinder, a clamping hydraulic cylinder and other devices; the first translation drive mechanism 226 can use a telescopic motor, a pen-shaped cylinder, a telescopic hydraulic cylinder and other devices. Preferably, the first clamping mechanism 225 uses a pen-shaped cylinder, the cylinder body of the pen-shaped cylinder is fixedly mounted on the limit frame 223, and the driving end of the pen-shaped cylinder is fixedly mounted on the first machine base 221.

[0033] In order to make the first base 221 have better stability in translation, in some optional embodiments, such as Figure 3 As shown, a first sliding plate 2232 is slidably provided on the limiting frame 223, and the first machine 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 matching the guide rail is provided at the bottom of the first sliding plate 2232. At this time, in order to prevent the limiting relationship between the limiting frame 223 and the first sliding plate 2232 from limiting the rotation of the first rotating arm 224, it is necessary to set the card slot 2231 as a stepped card slot, that is, the head and tail of the stepped card slot have a height difference, and the height of the side close to the sorting channel 2121 is lower.

[0034] In order to further ensure better stability in the translation of the first base 221 , in some optional embodiments, limit 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.

[0035] In some optional embodiments, such as Figure 5 , Figure 6As shown, the film punching mechanism 310 includes a conveying frame 311, and a roller-type rolling device 312, a punching rod 313 and a first telescopic driving mechanism 314 arranged on the conveying frame 311. The roller-type rolling device 312 includes a reel 3121 for winding an air film film, and a conveying roller 3122 for conveying the air film film. When working, the air film 122 on the conveying roller 3122 passes through the action area of ​​the punching rod 313, and the first telescopic driving mechanism 314 is connected to the punching rod 313 by transmission. When the first telescopic driving mechanism 314 is in working state, the driving end of the first telescopic driving mechanism 314 drives the punching rod 313 to reciprocately punch the air film film transmitted on the roller-type rolling device 312. Optionally, the first telescopic driving mechanism 314 can select a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder and the like.

[0036] In some optional embodiments, such as Figure 7 As shown, the object-carrying 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 rotating driving mechanism 323, a supporting platform 324, a vacuum suction head 325, and a second translation driving 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 rotating driving mechanism 323 is transmission-connected with the second rotating shaft 322, the supporting platform 324 is arranged on the second rotating shaft 322, the vacuum suction head 325 is slidably arranged on the supporting 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, the second translation driving mechanism 326 is arranged on the supporting platform 324, and the driving end of the second translation driving mechanism 326 is transmission-connected with the vacuum suction head 325.

[0037] During operation, the driving end of the rotary drive mechanism 323 drives the second rotating shaft 322 to rotate, so that the vacuum suction head 325 can be flipped and converted between the vertical state and the horizontal state, and the driving end of the second translation drive mechanism 326 drives the vacuum suction head 325 to slide on the support table 324 to control the lifting and placing of objects. In this way, through the cooperation of the rotary drive mechanism 323 and the second translation drive mechanism 326, the vacuum suction head 325 can change its position and angle posture, complete the operation of the vacuum suction head 325 sucking the air film 122 from the punch rod 313, and the vacuum suction head 325 places the picked-up air film 122 on the object carrier 110 loaded with the needle core 121. Optionally, the rotary drive mechanism 323 can use a rotary motor, a rotary cylinder, a rotary hydraulic cylinder and other devices, and the second translation drive mechanism 326 can use a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder and other devices.

[0038] In some optional embodiments, such as Figure 7As shown, the vacuum suction head 325 uses a telescopic suction head, and a buffer spring 3251 is set on the vacuum suction head 325. In this way, the impact force can be reduced when the vacuum suction head 325 touches the punch rod 313, thereby improving the picking accuracy of the vacuum suction head 325. At the same time, the impact force can also be reduced when the vacuum suction head 325 contacts the needle core 121 on the carrier component 110, thereby improving the placement accuracy of the vacuum suction head 325.

[0039] Considering the length of the carrier assembly 110 and the punching efficiency of the punching rod 313, in some scenarios, the arrangement length of the vacuum suction head 325 is shorter than the arrangement length of the punching rod 313, resulting in that the currently punched air film 122 cannot be picked up by the vacuum suction head 325 at one time. Figure 5 , Figure 6 As shown, a stepping drive mechanism 130, such as a stepping motor, is arranged on the workbench 100, and a conveying frame 311 is arranged on the driving end of the stepping drive mechanism 130. The stepping drive mechanism 130 moves the film punching mechanism 310 to the side by multiple equal distances, so that the second material picking and transfer mechanism 320 can pick up the single-punched air film 122 multiple times.

[0040] In some optional embodiments, such as Figure 8 As shown, the air film welding assembly 400 includes a heat insulation board 410, a heating rod 420, a welding head 430, and a first vertical driving mechanism 440. The fixed end of the first vertical driving mechanism 440 can be installed on the workbench 100 through a first supporting seat 450, the heat insulation board 410 surrounds to form a heat preservation cavity 411, the heating rod 420 is arranged in the heat preservation cavity 411, the heat insulation board 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 driving mechanism 440 is connected to the heat insulation board 410 in a transmission connection. During operation, the heating rod 420 heats the heat preservation chamber 411 until the temperature in the heat preservation chamber 411 rises to a preset temperature, and then the first vertical driving mechanism 440 drives the heat insulation plate 410 to move downward until the welding head 430 is at a preset welding position, at which 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 driving mechanism 440 can use a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder, and the like.

[0041] In some optional embodiments, such as Figure 1 As shown, a plurality of groups of air film welding assemblies 400 are sequentially arranged along the transmission path of the transmission platform 101 to improve the welding efficiency.

[0042] In some optional embodiments, such as Figure 8As shown, the heat insulation board 410 is slidably disposed on the first support seat 450 to improve the stability of the heat insulation board 410 moving up and down.

[0043] In some optional embodiments, such as Figure 8 As shown, a limit adjustment column 460 is provided on the moving path of the heat insulation board 410, and the limit adjustment column 460 can prevent the first vertical driving mechanism 440 from driving the heat insulation board 410 beyond the preset welding position, so that the needle core 121, the object carrier assembly 110, and the air film welding assembly 400 are not easily damaged by collision. Optionally, the limit adjustment column 460 is provided on the first support seat 450, or can be directly provided on the workbench 100.

[0044] In some optional embodiments, the limit adjustment column 460 includes a stopper and a screw. The screw can be set on the first support seat 450 or directly on the workbench 100. The stopper is fixedly mounted on the insulation board 410, and the contact height between the stopper and the screw is adjusted by adjusting the screwing depth of the screw.

[0045] In some optional embodiments, such as Figure 8 As shown, the air film welding assembly 400 further includes an anti-tilt lifting mechanism 470, which is disposed on the workbench 100. When the welding head 430 is welding, a force is applied downward, which may cause the transmission platform 101 to tilt, which is not conducive to precise assembly and welding. At this time, the anti-tilt lifting mechanism 470 is used to lift and push the transmission platform 101 upward to prevent the transmission platform 101 from tilting. Optionally, the anti-tilt lifting mechanism 470 can be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder, or the like.

[0046] In some optional embodiments, such as Fig. 9As shown, the object carrier assembly 110 is provided with a plurality of bearing positions arranged side by side, so that a plurality of assembly parts can be carried, thereby improving assembly efficiency. The image detection device 510 includes a third translation drive mechanism 511, an image sensor 512, a position sensor 513, and a plurality of induction triggering members 514. Specifically, the moving direction of the driving end of the third translation drive mechanism 511 is parallel to the arrangement direction of the bearing positions on the object carrier assembly 110, the image sensor 512 is arranged on the driving end of the third translation drive mechanism 511, the position sensor 513 is arranged on the image sensor, and the plurality of induction triggering members 514 are arranged at intervals along the moving direction of the driving end of the third translation drive mechanism 511, and the position of each induction triggering member 514 corresponds one by one to each bearing position on the object carrier 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 514 can be a photoelectric switch component, a combination of a magnetic sensor and a magnetic marking component, or a combination of a capacitive sensor and a metal sensor sheet, and the third translation drive mechanism 511 can be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder or the like.

[0047] In this embodiment, when the third translation drive mechanism 511 is in working state, the driving end of the third translation drive mechanism 511 drives the image sensor 512 to move, so that the image sensor 512 can sequentially capture each assembly part on the carrier assembly 110, and when the image sensor 512 moves to the position of a certain assembly part for shooting, the position sensor 513 on the image sensor 512 is aligned with the induction trigger 514, and the position sensor 513 generates a trigger signal at this time. The control system controls the third translation drive mechanism 511 to stop moving the image sensor 512 according to the trigger signal, thereby ensuring the alignment accuracy between the image sensor 512 and the assembly part on the carrier assembly 110. After completing a single test, it moves to the next test position. When the air film 122 and the needle core 121 are assembled together, the welded air film 122 will form a circle of weld lines on the surface of the needle core 121. At this time, the image is captured by the image sensor 512. The control system can judge whether the welding is qualified by comparing the image data collected by the image sensor 512 with the weld lines of good products.

[0048] In some optional embodiments, such as Fig.10As shown, the flow detection device 520 includes a second vertical drive mechanism 521, a vent pipe 522, a vent head 523, a spring 524, and a flow meter 525. Specifically, the fixed end of the second vertical drive mechanism 521 can be mounted on the workbench 100 through a second support seat 526, the moving direction of the driving end of the second vertical drive mechanism 521 intersects with the arrangement direction of the bearing positions on the object-carrying assembly 110, one end of the vent pipe 522 is fixed on the driving end of the second vertical drive mechanism 521, the vent head 523 is slidably disposed on the other end of the vent pipe 522, the vent head 523 is communicated with the vent pipe 522, the spring 524 is sleeved on the vent pipe 522, and is disposed between the vent head 523 and the driving end of the second vertical drive mechanism 521, the output end of the flow meter 525 is communicated with the air inlet end of the vent pipe 522, and the input end of the flow meter 525 is used to connect the gas delivery device. Optionally, the second vertical driving mechanism 521 may be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder or the like.

[0049] In this embodiment, when the second vertical driving mechanism 521 is in working state, the driving end of the second vertical driving mechanism 521 drives the vent pipe 522 to move downward until the vent head 523 is inserted into the corresponding position of the needle core 121 on the carrier assembly 110. During the plugging process, the vent head 523 slides upward relative to the lower end of the vent pipe 522, so that the spring 524 is compressed. The spring 524 generates a downward thrust so that the vent head 523 is tightly inserted into the corresponding position of the needle core 121 on the carrier 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 vent pipe 522 in sequence, and finally outputs from the vent head 523. The gas delivery device can precisely adjust the intake pressure by setting a precision pressure regulating valve 527, thereby reaching the intake pressure required for detection. When the air film 122 has an abnormal situation such as a broken film, the gas flow rate of the flow meter 525 will change, thereby judging whether the air film 122 has an airtightness defect.

[0050] Through the joint detection of the image detection device 510 and the flow 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.

[0051] In some optional embodiments, such as Fig.11As 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 of the transfer air inlet seat 123 is used to limit the air inlet seat 123 in a vertical state. The corresponding first material picking and transfer mechanism 220 includes a second fixed seat 231, a fourth translation drive mechanism 232, a third vertical drive mechanism 233, a material picking head 234, and a second telescopic drive mechanism 235. Specifically, the fixed end of the fourth translation drive 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 drive mechanism 233 is arranged on the driving end of the fourth translation drive mechanism 232, the material taking head 234 is arranged on the driving end of the third vertical drive mechanism 233, the middle part of the material taking head 234 is hollow, in order to ensure that the material taking head 234 can clamp the air inlet seat 123, the material taking head 234 and the air inlet seat 123 have an interference fit at the clamping position, the fixed end of the second telescopic drive mechanism 235 is arranged on the driving end of the third vertical drive mechanism 233, and the telescopic end of the second telescopic drive mechanism 235 can shuttle in the middle hollow part of the material taking head 234. Optionally, the fourth translation drive mechanism 232, the third vertical drive mechanism 233, and the second telescopic drive mechanism 235 can all use telescopic motors, telescopic cylinders, telescopic hydraulic cylinders and other devices. Preferably, both the fourth translation driving mechanism 232 and the third vertical driving mechanism 233 are pen-shaped cylinders.

[0052] In this embodiment, when the third vertical drive mechanism 233 is in working state, the driving end of the third vertical drive mechanism 233 drives the material picking head 234 to move downward until the material picking head 234 is inserted into the clamping position of the air inlet seat 123 on the sorting channel 2121, and then the driving end of the third vertical drive mechanism 233 drives the material picking head 234 to move upward, and the driving end of the fourth translation drive mechanism 232 then drives the third vertical drive mechanism 233 to move as a whole toward the side of the carrier component 110 until the air inlet seat 123 clamped on the material picking head 234 is aligned with the corresponding position of the assembly parts on the carrier component 110, and then the driving end of the third vertical drive mechanism 233 drives the material picking head 234 to move downward until the material picking head 234 is inserted into the corresponding position of the assembly parts on the carrier component 110, and finally the telescopic end of the second telescopic drive mechanism 235 extends to push the air inlet seat 123 out of the material picking head 234. When it is necessary to pick up the remaining air inlet seat 123 on the sorting channel 2121, first the telescopic end of the second telescopic driving mechanism 235 contracts, and then the driving end of the third vertical driving mechanism 233 drives the material picking head 234 to move upward, and then the driving end of the fourth translation driving mechanism 232 drives the third vertical driving mechanism 233 to move as a whole toward the side of the sorting channel 2121, and finally the driving end of the third vertical driving mechanism 233 drives the material picking head 234 to move downward.

[0053] In order to make the translation of the driving end of the fourth translation driving mechanism 232 have better stability, in some optional embodiments, such as Fig.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 mounted on the second sliding plate 236. Optionally, a guide rail can be installed on the second fixed seat 231, and a slider matching the guide rail is provided at the bottom of the second sliding plate 236.

[0054] In order to further ensure that the translation of the driving end of the fourth translation drive mechanism 232 has better stability, in some optional embodiments, limit 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.

[0055] In some optional embodiments, such as Fig.12 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 of the transfer cap 124 is used to limit the cap 124 in a vertical state. The corresponding first material picking and transfer mechanism 220 includes a third fixed seat 241, a fifth translation drive mechanism 242, a third rotating shaft 243, a second clamping mechanism 244, a second rotating arm 245, a third telescopic drive mechanism 246, and a fourth telescopic drive 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 arranged on the third fixed seat 241, the third rotating shaft 243 is rotatably arranged on the driving end of the fifth translation driving mechanism 242, the second clamping mechanism 244 is fixedly arranged on the third rotating shaft 243, when the second clamping mechanism 244 is in the clamping state, the second clamping mechanism 244 corresponds to the position 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 arranged 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 arranged on the third fixed seat 241, the telescopic end of the fourth telescopic driving mechanism 247 is set in an unloaded state and the telescopic direction is parallel to the placement direction of the needle core 121 on the carrier assembly 110.

[0056] 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 line connecting the output end of the sorting channel 2121 and the carrying position of the object 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, and then the telescopic end of the third telescopic driving mechanism 246 drives the second rotating arm 245 to rotate in the opposite direction, and then drives the third rotating shaft 243 to rotate in the opposite direction, so that the second clamping mechanism 244 horizontally clamps the protective cap 124, and then the fifth translation driving mechanism 242 moves toward the side of the carrier component 110. At this time, the second clamping mechanism 244 horizontally clamps the protective cap 124 and moves to the side of the carrier 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 carrier component 110, the telescopic end of the fourth telescopic driving mechanism 247 retracts quickly, and the protective cap 124 is sleeved on the needle core 121 by inertia force. Optionally, the second clamping mechanism 244 may be a clamping motor, a clamping cylinder, a clamping hydraulic cylinder, etc.; the fifth translation drive mechanism 242 may be a telescopic motor, a pen-shaped cylinder, a telescopic hydraulic cylinder, etc.; the third telescopic drive mechanism 246 and the fourth telescopic drive mechanism 247 may be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder, etc. It should be noted that in order to provide a suitable inertial force, the fourth telescopic drive mechanism 247 needs to select a model with a suitable thrust according to the actual situation.

[0057] It should also be noted that after the image detection device 510 and the flow detection device 520 have jointly detected and recorded 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 on unqualified products.

[0058] In some optional embodiments, such as Fig.12 As 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 from the second clamping mechanism 244 .

[0059] In some optional embodiments, such as Fig.12 As 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 rotating and getting stuck.

[0060] 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 stop of the third rotating shaft 243.

[0061] 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 Fig.12 As shown, a third sliding plate 248 is slidably provided on the third fixed seat 241, a driving end of the fifth translation driving mechanism 242 is fixedly connected to the third sliding plate 248, and the third rotating shaft 243 is rotatably provided on the third sliding plate 248. Optionally, a guide rail may be installed on the third fixed seat 241, and a slider cooperating with the guide rail may be provided at the bottom of the third sliding plate 248.

[0062] 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.

[0063] In some optional embodiments, such as Figure 1 As shown, the unloading assembly 800 includes a qualified product unloading assembly 810 and a failed product unloading assembly 820 which are sequentially arranged along the transmission path of the transmission platform 101 .

[0064] Specifically, Fig.13 As shown, the qualified product unloading assembly 810 includes a fourth vertical driving mechanism 811 and a sixth translation driving mechanism 812 that work in sequence. The total number of the fourth vertical driving mechanism 811 and the sixth translation driving mechanism 812 is consistent with the number of needle cores 121 placed on the object carrier assembly 110, and the fixed end of the fourth vertical driving mechanism 811 is fixedly installed on the workbench 100. During operation, the driving end of the fourth vertical driving mechanism 811 pushes up the second clamping block 114, and the positioning rod 113 drives the first clamping block 112 to move upward. At this time, the sandwich space formed between the first clamping block 112 and the mounting block 111 is expanded, and the clamping of the needle core 121 is released. At this time, the driving end of the sixth translation driving mechanism 812 pushes the needle core 121 horizontally, thereby removing the corresponding needle core 121 on the object 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. Fig.15As shown. Then, the carrier assembly 110 loaded with defective products is moved to the defective product unloading assembly 820 through the transmission platform 101. Optionally, the fourth vertical drive mechanism 811 and the sixth translation drive mechanism 812 can both use telescopic motors, pen-shaped cylinders, telescopic hydraulic cylinders and other devices. Preferably, the fourth vertical drive mechanism 811 and the sixth translation drive mechanism 812 both use pen-shaped cylinders.

[0065] like Fig.14 As shown, the unqualified 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 transmission 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 sandwich space formed between the first clamping block 112 and the mounting block 111 is expanded, 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 unqualified 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 ejector rods 8221, so that the seventh translation drive mechanism 822 can eject all defective products on the carrier assembly 110 by performing one extension and contraction.

[0066] In order to facilitate the collection of qualified products ejected by the sixth translation drive mechanism 812, in some optional embodiments, such as Fig.13 As shown, the qualified product unloading assembly 810 further includes a guide plate 813, which is disposed on the workbench 100, and the qualified products are moved to a preset collection device through the guiding function of the guide plate 813. At this time, in order to avoid interference between the installation position of the guide plate 813 and the position of the sixth translation drive mechanism 812, the fixed end of the sixth translation drive mechanism 812 is fixedly installed on the transmission platform 101.
