Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing equipment technology, specifically to an automatic assembly machine for sputum collection cups. Background Technology

[0002] Sputum collection cups are mainly composed of three parts: the cup body, the front cap, and the rear cap. These three parts are assembled by screwing on a screw thread. Currently, the industry primarily relies on manual operation to manufacture this type of sputum collection cup, which has several drawbacks. First, manual assembly is inefficient. Given the demand for large-scale medical testing, manually assembling each sputum collection cup individually cannot meet the needs of rapid testing processes, leading to prolonged overall testing time and impacting patient diagnosis and treatment progress. Second, manual operation is prone to errors. During assembly, the end cap may not be screwed on properly, potentially resulting in an incomplete seal and affecting sample preservation and the accuracy of test results. Third, during manual assembly, the operator's direct contact with the collection cup increases the risk of sample contamination, threatening the reliability of test results. Utility Model Content

[0003] The purpose of this invention is to provide an automatic assembly machine for sputum collection cups that can improve production efficiency and ensure the stability and consistency of sputum collection cup production.

[0004] An automatic sputum collection cup assembly machine includes a first machine base and a second machine base adjacent to the first machine base. The first machine base is equipped with a sleeve feeding vibratory feeder device, a first end cap feeding vibratory feeder device, and a second end cap feeding vibratory feeder device. The second machine base is equipped with a sleeve transport device for transporting sleeves conveyed by the sleeve feeding vibratory feeder device to the first conveying device, a first conveying device and a second conveying device for transporting sleeves, a first capping device and a second capping device for screwing end cap knobs onto the sleeves, a flipping and transferring device for flipping and transferring sleeves, a detection device, and a material unloading and transferring device.

[0005] In the above scheme, the sleeve conveying device transports the sleeve from the sleeve feeding vibratory feeder to the first conveying device. The first conveying device transports the sleeve to the position of the rotating end cap of the first capping device. The first end cap feeding vibratory feeder moves one end cap to the bottom of the first capping device. The first capping device takes out the end cap and screws it onto one end of the sleeve. Then, the flipping and transfer device flips the sleeve and transfers it to the second conveying device. The second conveying device transports the sleeve to the position of the rotating end cap of the second capping device. The second end cap feeding vibratory feeder moves the other end cap to the bottom of the second capping device. The second capping device takes out the end cap and screws it onto the other end of the sleeve. Then, the second conveying device transports the sleeve to the front of the detection device. When the unloading and transfer device takes the sleeve out of the second conveying device, the detection device can detect whether the front and rear end caps have rotated into place. This automated assembly machine integrates multiple processes such as feeding, handling, assembly, testing, and unloading into a complete automated production process. The assembly efficiency of sputum collection cups has been significantly improved, meeting the needs of large-scale medical testing. Through the first and second capping devices, the end caps can be precisely screwed onto both ends of the sleeve, avoiding the sealing problems caused by improper screwing during manual operation. The entire assembly process is completed automatically inside the machine, reducing direct contact between operators and collection cups and lowering the risk of sample contamination. The testing device can detect whether the front and rear end caps have been rotated into place after assembly, ensuring the stability and consistency of sputum collection cup production.

[0006] Furthermore, the sleeve conveying device includes a support frame, a first linear motor module, a lifting drive component, and a first finger cylinder. The support frame is mounted on the second machine base, the first linear motor module is mounted on the support frame, the lifting drive component is movably connected to the first linear motor module, the first finger cylinder is connected to the drive end of the lifting drive component, and the two output ends of the first finger cylinder are connected to two first clamping blocks.

[0007] In the above scheme, the support frame supports the first linear motor module, which is suspended above the first conveying device and the sleeve feeding vibratory feeder device. The first linear motor module drives the lifting drive and the first finger cylinder to move back and forth between the sleeve feeding vibratory feeder device and the first conveying device. The lifting drive drives the first finger cylinder to move up and down. The first finger cylinder can drive the two clamping blocks to open and close, thereby transporting the sleeve on the sleeve feeding vibratory feeder device to the first conveying device, which improves the accuracy and efficiency of sleeve transportation.

[0008] Furthermore, the first conveying device includes a mounting frame, a drive mechanism, and a conveying mechanism. The mounting frame is mounted on the second machine base, the conveying mechanism is mounted on the mounting frame, the drive mechanism is connected to the conveying mechanism, and the conveying mechanism includes a synchronous belt, synchronous pulleys, and placement seats. Two synchronous pulleys are respectively mounted at both ends of the mounting frame, the synchronous belt is wound around the synchronous pulleys, and multiple placement seats are connected to the synchronous belt.

[0009] In the above scheme, the mounting frame is used to support the conveying mechanism, and the drive mechanism is used to drive one of the synchronous pulleys on the conveying mechanism to rotate. The synchronous pulley will drive the synchronous belt to convey. Multiple placement seats are connected to the synchronous belt. When the synchronous belt moves, the placement seats will also move with the synchronous belt. After the sleeve transport device transports the sleeve to the placement seat, the placement seat will transport the sleeve to the position of the rotating end cap of the first capping device with the cyclic movement of the synchronous belt, thereby realizing the continuous transport of the sleeve on the first conveying device.

[0010] Furthermore, the mounting frame is provided with symmetrical clamping mechanisms on both sides. The clamping mechanism includes a mounting plate, a pushing cylinder, and a clamping block. The mounting plate is connected to the mounting frame, the pushing cylinder is mounted on the mounting plate, and the clamping block is connected to the driving end of the pushing cylinder.

[0011] In the above scheme, when the sleeve is delivered to the position of the rotating end cap of the first capping device, the clamping mechanism on both sides of the mounting frame will clamp the sleeve. Specifically, the push cylinder pushes the clamping block to move towards the sleeve until the two clamping blocks clamp the sleeve, ensuring the stability of the sleeve when the first capping device rotates the end cap. This effectively avoids problems such as the end cap being tilted or not being tightened due to the sleeve shaking, and greatly improves the assembly accuracy and sealing performance of the sputum collection cup.

[0012] Furthermore, the first capping device includes a lifting drive mechanism, a connecting base plate, and a rotating drive mechanism. The connecting base plate is connected to the lifting drive mechanism, the rotating drive mechanism is connected to the connecting base plate, and the rotating drive mechanism is connected to a clamping assembly.

[0013] In the above solution, the clamping assembly is used to clamp the end cap, and the connecting base plate connects the rotary drive mechanism and the lifting drive mechanism. In this way, the lifting drive mechanism can drive the rotary drive mechanism to move back and forth in the vertical direction. By driving the clamping assembly to rotate through the rotary drive mechanism and cooperating with the lifting drive mechanism to drive the clamping assembly to move up and down, the end cap can be automatically screwed onto the sleeve, thereby improving production efficiency and avoiding problems such as the cap being too loose, too tight, or twisted due to the uncertainty of manual operation, thus ensuring the stability and consistency of the capping quality.

[0014] Furthermore, the rotary drive mechanism includes a fixed frame, a rotary drive assembly, a rotary shaft, an electric slip ring, and a connector. The fixed frame is mounted on the connecting base plate, the rotary drive assembly is mounted on the fixed frame, a bearing is provided on the connecting base plate, one end of the rotary shaft passes through the bearing and is connected to the rotary drive assembly, the connector is sleeved on the other end of the rotary shaft, the elastic element at the bottom of the connector abuts against the rotary shaft, and the electric slip ring is sleeved on the connecting shaft and located between the connecting base plate and the connector.

[0015] In the above scheme, when the rotary drive assembly is started, it generates rotational power. One end of the rotating shaft passes through a bearing on the connecting base plate and is connected to the rotary drive assembly. The bearing provides support and reduces friction, allowing the rotating shaft to rotate smoothly under the drive of the rotary drive assembly. The rotating shaft transmits the power of the rotary drive assembly to the connector, which in turn drives the clamping assembly connected to the connector to rotate, realizing the rotation operation of the end cap. This mechanism can ensure the accuracy and stability of the capping. The elastic element can play a buffering role, avoiding damage to the end cap, sleeve, or equipment itself due to rigid contact. Since the rotating shaft and connector are constantly rotating, ordinary wire connection methods cannot meet the electrical transmission requirements during the rotation process. The role of the electric slip ring is to achieve a reliable electrical connection between the rotating and stationary parts.

[0016] Furthermore, the clamping assembly includes a three-jaw cylinder, a connecting block, and a second clamping block. The three connecting blocks are respectively connected to the three sliders of the three-jaw cylinder. The second clamping block is connected to the connecting blocks, and the second clamping block is provided with an arc-shaped slot.

[0017] In the above scheme, the three-jaw cylinder uses compressed air as a power source, which can quickly realize the movement of the slider, thereby driving the second clamping block to quickly complete the clamping and releasing action. On the automated production line, this fast response characteristic can greatly improve production efficiency and reduce the processing time of a single product. The arc-shaped groove on the second clamping block is adapted to the shape of the end cap, which can closely fit the surface of the end cap. This not only increases the contact area during clamping and improves the friction, making the clamping more secure, but also avoids damage to the surface of the end cap to a certain extent.

[0018] Furthermore, the turning and transferring device includes a horizontal drive mechanism, a sliding lifting mechanism, a rotary cylinder, and a second finger cylinder. The sliding lifting mechanism is connected to the horizontal drive mechanism, the rotary cylinder is movably connected to the sliding lifting mechanism, the second finger cylinder is connected to the rotary cylinder, and the two output ends of the second finger cylinder are connected to a third clamping block.

[0019] In the above scheme, when the horizontal drive mechanism and the sliding lifting mechanism work together, the rotary cylinder and the second finger cylinder can be moved to the required horizontal and vertical positions. The rotary cylinder is driven by air pressure, which can drive the second finger cylinder connected to it to rotate around a specific axis. When air pressure enters the second finger cylinder, the two output ends will move towards each other, driving the third clamping block connected to it to move closer, thereby clamping the workpiece. When the air pressure is released or reversed, the two output ends move away from each other, and the third clamping block releases the workpiece, completing the clamping and releasing operation of the workpiece. This realizes the transfer of one end of the sleeve knob and end cap downward to the second conveying device, thereby improving the overall production efficiency.

[0020] Furthermore, the detection device and the material feeding and transfer device are respectively located on both sides of the second conveying device. The detection device includes two sets of inclined detection mechanisms. The detection mechanism includes a first light source assembly, a second light source assembly, and a camera assembly. The camera assembly is located on the side of the first light source assembly and the second light source assembly away from the second conveying device.

[0021] In the above scheme, two sets of inclined detection mechanisms illuminate and acquire images of the sleeve from different angles, which can more comprehensively detect all parts of the sleeve and improve the accuracy of detection. The first light source assembly and the second light source assembly provide sufficient light for the sleeve, enabling the camera assembly to gradually capture clear image details, so that the installation of the two end caps can be presented more clearly under suitable lighting conditions.

[0022] Furthermore, the first end cap feeding vibratory feeder device includes a vibratory feeder mechanism, a vibratory feeder discharging mechanism, and a pressing mechanism;

[0023] The pressing mechanism includes an overlapping plate, a pressing cylinder, and a pressing block. The overlapping plate is installed above the discharge end of the discharge track of the vibratory feeder mechanism. The pressing cylinder is installed on the overlapping plate, and the pressing block is connected to the output end of the pressing cylinder.

[0024] The vibratory feeder discharge mechanism includes a support base, a slider, a guide rail, a discharge drive cylinder, and a discharge block. The slider is mounted on the support base, the guide rail is slidably connected to the slider, the discharge block is connected to the guide rail, the discharge drive cylinder is connected to the support base, and the output end of the discharge drive cylinder is connected to the discharge block.

[0025] In the above scheme, the vibratory feeder mechanism realizes the orderly transfer and feeding of end caps, and the pressing mechanism is used to press the end caps. When an end cap is transferred to the vibratory feeder discharge mechanism, the pressing cylinder drives the pressing block to press down on the end cap. The overlapping plate provides support for the pressing cylinder. The vibratory feeder discharge mechanism transfers the end cap to the bottom of the first capping device. Specifically, the discharge driving cylinder drives the discharge block to move towards the first capping device. Since the slider is installed on the support base, the guide rail is connected to the slider, and the discharge block is connected to the guide rail, the discharge block and the guide rail can slide along the slider to ensure the stability and accuracy of the end cap transfer.

[0026] This utility model discloses an automatic sputum collection cup assembly machine, which has the beneficial effects of improving production efficiency and ensuring the stability and consistency of sputum collection cup production. A sleeve transport device transports the sleeves from the sleeve feeding vibratory feeder to a first conveying device. The first conveying device transports the sleeves to the position of the rotating end cap of the first capping device. The first end cap feeding vibratory feeder moves one end cap to the bottom of the first capping device, which removes the end cap and screws it onto one end of the sleeve. Then, a flipping and transfer device flips the sleeve and transfers it to a second conveying device. The second conveying device transports the sleeve to the position of the rotating end cap of the second capping device. The second end cap feeding vibratory feeder moves the other end cap to the bottom of the second capping device, which removes the end cap and screws it onto the other end of the sleeve. Then, the second conveying device transports the sleeve to the front of a detection device. When the unloading and transfer device removes the sleeve from the second conveying device, the detection device can detect whether the front and rear end caps have rotated into place.

[0044] The present invention provides a more detailed description of an automatic sputum collection cup assembly machine in conjunction with specific embodiments and accompanying drawings.

[0045] like Figure 1 and Figure 2 As shown in a preferred embodiment, the present invention provides an automatic sputum collection cup assembly machine, comprising a first machine base 1 and a second machine base 2 arranged adjacent to the first machine base 1. The first machine base 1 is equipped with a sleeve feeding vibratory feeder device 11, a first end cap feeding vibratory feeder device 12, and a second end cap feeding vibratory feeder device 13. The second machine base 2 is equipped with a sleeve transport device 3 for transporting the sleeves conveyed by the sleeve feeding vibratory feeder device 11 to a first conveying device 4, a first conveying device 4 and a second conveying device 8 for transporting the sleeves, a first capping device 5 and a second capping device 7 for screwing the end cap knobs onto the sleeves, a flipping and transferring device 6 for flipping and transferring the sleeves, a detection device 9, and a feeding and transferring device 10.

[0046] In the above embodiment, the sleeve conveying device 3 transports the sleeve from the sleeve feeding vibratory feeder device 11 to the first conveying device 4. The first conveying device 4 transports the sleeve to the position of the first capping device 5 rotating the end cap. The first end cap feeding vibratory feeder device 12 moves one end cap to the bottom of the first capping device 5. The first capping device 5 takes out the end cap and twists it onto one end of the sleeve. Then, the flipping and transfer device 6 flips the sleeve and transfers it to the second conveying device 8. The second conveying device 8 transports the sleeve to the position of the second capping device 7 rotating the end cap. The second end cap feeding vibratory feeder device 13 moves the other end cap to the bottom of the second capping device 7. The second capping device 7 takes out the end cap and twists it onto the other end of the sleeve. Then, the second conveying device 8 transports the sleeve to the front of the detection device 9. When the unloading and transfer device 10 takes the sleeve out of the second conveying device 8, the detection device 9 can detect whether the front and rear end caps have been rotated into place.

[0047] This automatic assembly machine integrates multiple processes such as feeding, handling, assembly, testing, and unloading into a complete automated production process. The assembly efficiency of sputum collection cups has been significantly improved, meeting the needs of large-scale medical testing. Through the first capping device 5 and the second capping device 7, the end caps can be precisely screwed onto both ends of the sleeve, avoiding the problem of poor sealing caused by improper screwing during manual operation. The entire assembly process is completed automatically inside the machine, reducing direct contact between operators and collection cups and lowering the risk of sample contamination. The testing device 9 can detect whether the front and rear end caps have been rotated into place after assembly, ensuring the stability and consistency of sputum collection cup production.

[0048] like Figure 4 As shown, in some embodiments, the sleeve conveying device 3 includes a support frame 31, a first linear motor module 32, a lifting drive component 33, and a first finger cylinder 34. The support frame 31 is mounted on the second machine base 2, the first linear motor module 32 is mounted on the support frame 31, the lifting drive component 33 is movably connected to the first linear motor module 32, the first finger cylinder 34 is connected to the drive end of the lifting drive component 33, and the two output ends of the first finger cylinder 34 are connected to two first clamping blocks 35. The support frame 31 supports the first linear motor module 32, which is suspended above the first conveying device 4 and the sleeve feeding vibratory feeder device 11. The first linear motor module 32 drives the lifting drive component 33 and the first finger cylinder 34 to move back and forth between the sleeve feeding vibratory feeder device 11 and the first conveying device 4. The lifting drive component 33 drives the first finger cylinder 34 to move up and down. The first finger cylinder 34 can drive the two clamping blocks to open and close, thereby transporting the sleeve on the sleeve feeding vibratory feeder device 11 to the first conveying device 4, improving the accuracy and efficiency of sleeve transport.

[0049] like Figure 5 As shown, in some embodiments, the first conveying device 4 includes a mounting frame 41, a drive mechanism 42, and a conveying mechanism 43. The mounting frame 41 is mounted on the second machine base 2, the conveying mechanism 43 is mounted on the mounting frame 41, the drive mechanism 42 is connected to the conveying mechanism 43, and the conveying mechanism 43 includes a synchronous belt 431, synchronous pulleys 432, and placement seats 433. Two synchronous pulleys 432 are respectively mounted on both ends of the mounting frame 41, the synchronous belt 431 is wound around the synchronous pulleys 432, and multiple placement seats 433 are connected to the synchronous belt 431. Mounting bracket 41 is used to support conveying mechanism 43, and drive mechanism 42 is used to drive one of the synchronous pulleys 432 on conveying mechanism 43 to rotate. Synchronous pulley 432 will drive synchronous belt 431 to convey. Multiple placement seats 433 are connected to synchronous belt 431. When synchronous belt 431 moves, placement seats 433 will also move with synchronous belt 431. After sleeve conveying device 3 transports sleeve to placement seat 433, placement seat 433 will transport sleeve to the position of rotating end cap of first capping device 5 with the cyclic movement of synchronous belt 431, thereby realizing continuous conveying of sleeve on first conveying device 4.

[0050] The second conveying device 8 has the same structure as the first conveying device 4, and the structure and principle of the second conveying device 8 will not be described in detail here.

[0051] like Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, the mounting frame 41 is provided with symmetrical clamping mechanisms 44 on both sides. The clamping mechanism 44 includes a mounting plate 441, a pushing cylinder 442, and a clamping block 443. The mounting plate 441 is connected to the mounting frame 41, the pushing cylinder 442 is mounted on the mounting plate 441, and the clamping block 443 is connected to the drive end of the pushing cylinder 442. When the sleeve is transported to the position of the rotating end cap of the first capping device 5, the clamping mechanisms 44 on both sides of the mounting frame 41 will clamp the sleeve. Specifically, the pushing cylinder 442 pushes the clamping block 443 to move towards the sleeve until the two clamping blocks 443 clamp the sleeve, ensuring the stability of the sleeve when the first capping device 5 rotates the end cap. This effectively avoids problems such as the end cap being tilted or not tightened due to the sleeve shaking, and greatly improves the assembly accuracy and sealing performance of the sputum collection cup.

[0052] In this embodiment, a clamping mechanism 44 is also installed on the second conveying device 8. The structure and principle of the clamping mechanism 44 are the same as those of the first conveying device 4.

[0053] like Figures 8 to 10As shown, in some embodiments, the first capping device 5 includes a lifting drive mechanism 5142, a connecting base plate 52, and a rotating drive mechanism 53. The connecting base plate 52 is connected to the lifting drive mechanism 5142, and the rotating drive mechanism 53 is connected to the connecting base plate 52. The rotating drive mechanism 53 is connected to a clamping assembly 54. The clamping assembly 54 is used to clamp the end cap. The connecting base plate 52 connects the rotating drive mechanism 53 to the lifting drive mechanism 5142, so that the lifting drive mechanism 5142 can drive the rotating drive mechanism 53 to move back and forth in the vertical direction. By driving the clamping assembly 54 to rotate through the rotating drive mechanism 53 and cooperating with the lifting drive mechanism 5142 to drive the clamping assembly 54 to move up and down, the end cap can be automatically screwed onto the sleeve, thereby improving production efficiency and avoiding problems such as capping being too loose, too tight, or twisted due to the uncertainty of manual operation, thus ensuring the stability and consistency of capping quality.

[0054] In the above embodiments, the lifting drive mechanism 5142 mainly consists of a mounting bracket and a linear motor, which drives the connecting base plate 52 to rise and fall. The second capping device 7 has the same structure as the first capping device 5, and its structure and principle will not be described in detail here.

[0055] like Figures 8 to 10 As shown, in some embodiments, the rotary drive mechanism 53 includes a fixed frame 531, a rotary drive assembly 532, a rotary shaft 533, an electric slip ring 534, and a connector 535. The fixed frame 531 is mounted on the connecting base plate 52, the rotary drive assembly 532 is mounted on the fixed frame 531, the connecting base plate 52 is provided with a bearing 536, one end of the rotary shaft 533 passes through the bearing 536 and is connected to the rotary drive assembly 532, the connector 535 is sleeved on the other end of the rotary shaft 533, the elastic element 537 at the bottom of the connector 535 abuts against the rotary shaft 533, and the electric slip ring 534 is sleeved on the connecting shaft and located between the connecting base plate 52 and the connector 535.

[0056] When the rotary drive assembly 532 is started, it generates rotational power. One end of the rotary shaft 533 passes through the bearing 536 on the connecting base plate 52 and is connected to the rotary drive assembly 532. The bearing 536 provides support and reduces friction, allowing the rotary shaft 533 to rotate smoothly under the drive of the rotary drive assembly 532. The rotary shaft 533 transmits the power of the rotary drive assembly 532 to the connector 535, which in turn drives the clamping assembly 54 connected to the connector 535 to rotate, realizing the rotation operation of the end cap. This mechanism can ensure the accuracy and stability of the cap screwing.

[0057] In addition, the elastic element 537 can act as a buffer to prevent damage to the end cover, sleeve or equipment itself due to rigid contact. Since the rotating shaft 533 and the connecting element 535 are constantly rotating, ordinary wire connection methods cannot meet the electrical transmission requirements during the rotation process. The function of the electric slip ring 534 is to achieve a reliable electrical connection between the rotating part and the stationary part.

[0058] like Figures 8 to 10 As shown, in some embodiments, the clamping assembly 54 includes a three-jaw cylinder 541, a connecting block 542, and a second clamping block 543. The three connecting blocks 542 are respectively connected to the three sliders 1232 of the three-jaw cylinder 541. The second clamping block 543 is connected to the connecting blocks 542 and has an arc-shaped slot 5431. The three-jaw cylinder 541 uses compressed air as a power source, which can quickly move the sliders 1232, thereby driving the second clamping block 543 to quickly complete the clamping and releasing actions. In automated production lines, this rapid response characteristic can greatly improve production efficiency and reduce the processing time of a single product. The arc-shaped slot 5431 on the second clamping block 543 is adapted to the shape of the end cap and can closely fit the surface of the end cap. This not only increases the contact area during clamping and improves the friction, making the clamping more secure, but also avoids damage to the surface of the end cap to a certain extent.

[0059] like Figure 11 As shown, in some embodiments, the turning and transferring device 6 includes a horizontal drive mechanism 6142, a sliding lifting mechanism 62, a rotary cylinder 63, and a second finger cylinder 64. The sliding lifting mechanism 62 is connected to the horizontal drive mechanism 6142, the rotary cylinder 63 is movably connected to the sliding lifting mechanism 62, the second finger cylinder 64 is connected to the rotary cylinder 63, and the two output ends of the second finger cylinder 64 are connected to a third clamping block 65. When the horizontal drive mechanism 6142 and the sliding lifting mechanism 62 work together, the rotary cylinder 63 and the second finger cylinder 64 can be moved to the required horizontal and vertical positions. The rotary cylinder 63 is driven by air pressure, which can drive the second finger cylinder 64 connected to it to rotate around a specific axis. When air pressure enters the second finger cylinder 64, the two output ends will move towards each other, driving the third clamping block 65 connected to it to move closer, thereby clamping the workpiece. When the air pressure is released or reversed, the two output ends move away from each other, and the third clamping block 65 releases the workpiece, completing the clamping and releasing operation of the workpiece, thereby realizing the transfer of one end of the sleeve knob and end cap downward to the second conveying device 8, thereby improving the overall production efficiency.

[0060] In this embodiment, the feeding and transplanting device 10 and the turning and transplanting device 6 have basically the same structure. Since the feeding and transplanting device 10 does not require a rotating sleeve during the production process, the rotating cylinder 63 can be eliminated, and the second finger cylinder 64 can be directly connected to the sliding lifting mechanism 62.

[0061] like Figure 3 and Figure 12 As shown, in some embodiments, the detection device 9 and the feeding and transferring device 10 are located on opposite sides of the second conveying device 8. The detection device 9 includes two sets of inclined detection mechanisms 91. Each detection mechanism 91 includes a first light source assembly 911, a second light source assembly 912, and a camera assembly 913. The camera assembly 913 is located on the side of the first light source assembly 911 and the second light source assembly 912 away from the second conveying device 8. The two sets of inclined detection mechanisms 91 illuminate and acquire images of the sleeve from different angles, enabling more comprehensive detection of various parts of the sleeve and improving the accuracy of the detection. The first light source assembly 911 and the second light source assembly 912 provide sufficient light for the sleeve, allowing the camera assembly 913 to gradually capture clear image details, so that the installation of the two end caps can be more clearly presented under suitable lighting conditions. Here, the camera assembly 913 is equipped with two vertically distributed cameras, which can detect the front end cap and the rear end cap respectively.

[0062] like Figure 2 , Figure 6 and Figure 13 As shown, in some embodiments, the first end cap feeding vibratory feeder device 12 includes a vibratory feeder mechanism 121, a vibratory feeder discharging mechanism 123, and a pressing mechanism 122. The pressing mechanism 122 includes an overlapping plate 1221, a pressing cylinder 1222, and a pressing block 1223. The overlapping plate 1221 is installed above the discharge end of the discharge track 1211 of the vibratory feeder mechanism 121. The pressing cylinder 1222 is installed on the overlapping plate 1221, and the pressing block 1223 is connected to the output end of the pressing cylinder 1222. The vibratory feeder mechanism 121 realizes the orderly transfer and feeding of end caps, and the pressing mechanism 122 is used to press the end caps. When an end cap is transferred to the vibratory feeder discharging mechanism 123, the pressing cylinder 1222 drives the pressing block 1223 to press down on the end cap, and the overlapping plate 1221 provides support for the pressing cylinder 1222.

[0063] like Figure 14As shown, the vibratory feeder discharge mechanism 123 includes a support base 1231, a slider 1232, a guide rail 1233, a discharge drive cylinder 1234, and a discharge block 1235. The slider 1232 is mounted on the support base 1231, the guide rail 1233 is slidably connected to the slider 1232, the discharge block 1235 is connected to the guide rail 1233, the discharge drive cylinder 1234 is connected to the support base 1231, and the output end of the discharge drive cylinder 1234 is connected to the discharge block 1235. The vibratory feeder discharge mechanism 123 moves the end cap to below the first capping device 5. Specifically, the discharge drive cylinder 1234 drives the discharge block 1235 to move towards the first capping device 5. Since the slider 1232 is mounted on the support base 1231, the guide rail 1233 is connected to the slider 1232, and the discharge block 1235 is connected to the guide rail 1233, the discharge block 1235 and the guide rail 1233 can slide along the slider 1232 to ensure the stability and accuracy of the end cap transfer.

[0064] It should be noted that the vibratory feeder mechanism 121 used for feeding materials in the sleeve feeding vibratory feeder device 11, the first end cover feeding vibratory feeder device 12, and the second end cover feeding vibratory feeder device 13 in this embodiment all adopt conventional vibratory feeders. The structure and principle of the vibratory feeder mechanism 121 will not be described in detail here.

[0065] The working principle and process of this utility model of an automatic sputum collection cup assembly machine are as follows: First, the sleeve conveying device 3 transports the sleeve from the sleeve feeding vibratory feeder device 11 to the first conveying device 4. Then, the first conveying device 4 transports the sleeve to the position of the first capping device 5 for rotating the end cap. The first end cap feeding vibratory feeder device 12 moves an end cap to below the first capping device 5. After the clamping mechanism 44 clamps the sleeve, the first capping device 5 removes the end cap and screws it onto one end of the sleeve. Finally, the flipping and transfer device 6 flips the sleeve and transfers it to the second conveying device 8. The second conveying device 8 conveys the sleeve to the position of the rotating end cap of the second capping device 7. The second end cap feeding vibrating plate device 13 moves another end cap to the bottom of the second capping device 7. The second capping device 7 takes out the end cap and screws it onto the other end of the sleeve. Then the second conveying device 8 conveys the sleeve to the front of the detection device 9. The unloading and transfer device 10 takes the sleeve out from the placement seat 433 in the second conveying device 8. After the detection device 9 completes the detection of whether the front and rear end caps are rotated into place, the unloading and transfer device 10 performs the subsequent unloading work of the hand sputum collection cup.
