Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically a device that can automatically open and close test tube caps. Background Technology

[0002] In the biomedical industry, in vitro embryo culture requires a large number of in vitro embryos for verification, as well as operations such as opening test tubes, injecting chemicals, and closing the tubes. This process involves high labor costs, low production efficiency, and the inability to guarantee sterile environmental conditions.

[0003] Traditionally, opening and closing test tube caps relies on manual operation. This is not only inefficient and unsuitable for large-scale sample processing, but also leads to worker fatigue due to prolonged repetitive tasks, affecting accuracy and consistency. Especially when handling potentially hazardous samples, such as biological samples or chemical reagents, manual operation can pose safety risks, such as sample leakage or personnel infection. Furthermore, manually opening and closing test tube caps presents the challenge of precisely controlling the force applied, potentially resulting in incomplete seals or damage, thus impacting sample quality and the reliability of experimental results. Summary of the Invention

[0004] The purpose of this invention is to provide a device that can automatically open and close test tube caps, so as to solve the problems of high labor costs and inability to guarantee sterile conditions in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic test tube cap opening and closing device is used to automatically open and tighten the caps of several test tubes. The device includes a cap removal mechanism, a clamping mechanism, and a feeding and discharging mechanism. The cap removal mechanism includes several contouring heads; The clamping mechanism includes a base plate, on which several sets of placement holes are provided; The feeding and discharging mechanism includes a bottom box and a tray. The bottom box is provided with several sets of placement slots, and the bottom box is located above one end of the tray. The number of contouring heads, test tubes, placement holes, and placement slots are matched. Several test tubes are placed in several sets of placement slots in the base box, and several contouring heads pass through several sets of placement holes in the base plate. The shape of the lower surface of the contouring head matches the shape of the upper surface of the test tube cap. The contouring head ensures that the automatic opening and closing of several test tube caps are consistent.

[0006] Several test tubes are placed into the slots on the base box. After the test tubes are secured, the feeding and discharging mechanism automatically feeds and discharges the test tubes, improving the automation level and efficiency of the entire device. The tray moves to below the clamping mechanism, causing the base box to move the test tubes to below the capping mechanism. The clamping mechanism restricts the position of the capping mechanism. Since the copying head passes through the placement hole, the clamping mechanism can move the copying head up and down. When the test tube moves to below the copying head, the base plate moves downward, causing the copying head to move downward until the lower end of the copying head abuts against the cap of the test tube. Then, the copying head is rotated. Through the specific structural design of the copying head and the test tube cap, the cap is automatically opened or tightened. Through the coordinated work of various mechanisms, the automatic opening and tightening of caps on several test tubes is achieved, ensuring the consistency of test tube cap opening and closing, improving work efficiency, reducing the labor intensity and error of manual operation, and reducing human-caused contamination.

[0007] Furthermore, the cap removal mechanism also includes a cap removal circuit board, which is electrically connected to several cap removal motors. The output end of the cap removal motor is provided with a pin, the lower end of the pin is provided with a retractable copper sleeve, and the lower end of the retractable copper sleeve is provided with a contour head. When removing the cap: the bottom box is placed below the copying head, and the lower surface of the copying head abuts against the cap of the test tube.

[0008] After receiving a control signal from the capping circuit board, the capping motor starts running, driving the ejector pin to rotate. This, in turn, drives the retractable copper sleeve below the ejector pin to rotate, further driving the contour head at the lower end of the retractable copper sleeve to rotate. When the lower end of the contour head contacts the cap of the test tube, the contour head, due to its matching shape with the cap, rotates under the force generated by the continuous operation of the capping motor, causing the cap to rotate and thus automatically opening the cap. If tightening the cap is required, the capping motor is controlled to rotate in the opposite direction, following the reverse process to cause the contour head to rotate the cap in the opposite direction, tightening the cap onto the test tube. The entire capping process, through the precise control of the capping motor by the capping circuit board and the coordinated operation between the retractable copper sleeve, ejector pin, and contour head, ensures the accuracy and stability of the capping action, efficiently completing the automatic opening and closing operation of the test tube cap.

[0009] Furthermore, the clamping mechanism also includes a chain, a support plate, a rotating shaft, and a transition plate. A clamping motor is located below the support plate, and a first sprocket is located at the output end of the clamping motor. A second sprocket is mounted on the outer sleeve of the rotating shaft. The chain meshes with the first sprocket and the second sprocket respectively. Several tensioning wheels are located above the support plate, and these tensioning wheels abut against the chain. The support plate and the rotating shaft are rotatably connected, and the rotating shaft and the transition plate are threadedly connected. A base plate is located above the transition plate.

[0010] After the clamping motor starts, the first sprocket at its output end begins to rotate, driving the chain. Since the chain is also meshed with the second sprocket, the rotating shaft also rotates with the chain. Several tensioning wheels are used to tension the chain, making it interlocked with the first and second sprockets to prevent slippage during rotation. The rotating shaft is threadedly connected to the transition plate. When the rotating shaft rotates, the transition plate moves up and down along the axial direction of the rotating shaft. A base plate is set above the transition plate, and it moves up and down synchronously with the transition plate. The base plate has several sets of placement holes for stable placement of test tubes. When the base plate moves up and down, it can drive the copying head to move up and down, so that when the feeding and discharging mechanism drives the test tubes into and out of the device, the copying head is located at a higher position above the test tube, preventing the copying head from interfering with the test tubes during movement. When the test tube reaches the cap removal station, the copying head is driven down until it abuts against the test tube cap.

[0011] Furthermore, the support plate is provided with several sets of upper through holes, and the transition plate is provided with several sets of lower through holes, with the positions of the several sets of upper through holes, lower through holes and placement holes corresponding to each other; The ejector pin passes through the upper through hole, and the retractable copper sleeve passes through the lower through hole.

[0012] The above structure allows the ejector pin and the retractable copper sleeve to rotate freely within the upper and lower through holes, while ensuring their stability and accuracy during movement. When the clamping motor drives the chain to move, which in turn moves the transition plate up and down, the ejector pin and the retractable copper sleeve will move synchronously with the movement of the transition plate, ensuring that the profiling head can accurately contact and separate from the cap of the test tube, thereby realizing the automatic opening and tightening operation of the test tube cap.

[0013] Furthermore, the feeding and discharging mechanism also includes a feeding and discharging motor and a sliding rail. The output end of the feeding and discharging motor is provided with a first pulley, and a feeding and discharging belt is provided on the first pulley. The feeding and discharging belt and the first pulley abut against each other. A connecting member is provided on the feeding and discharging belt, and a tray is provided on one side of the connecting member. The tray is slidably connected to the sliding rail.

[0014] When the feeding and discharging motor is running, the first pulley at its output end drives the feeding and discharging belt to move. Since there is a connector fixed on the feeding and discharging belt, the connector moves synchronously with the movement of the feeding and discharging belt. A tray is connected to one side of the connector, and the tray is placed on a sliding rail. Therefore, when the connector moves, it will drive the tray to slide on the sliding rail. A bottom box is set above one end of the tray, which is used to hold the test tubes to be operated. Through this structural design, the feeding and discharging mechanism can realize the automatic feeding and discharging of test tubes. When it is necessary to send the test tube into the device for operation, the feeding and discharging motor rotates forward, driving the tray and bottom box to move into the device. After the operation is completed, the feeding and discharging motor reverses, driving the tray and bottom box to move out of the device, so as to facilitate the removal of the operated test tubes. This automatic feeding and discharging design improves the automation level and working efficiency of the entire device.

[0015] Furthermore, the device for automatically opening and closing test tube caps also includes a lifting mechanism, a frame, and a housing, with the frame inside the housing and the lifting mechanism on the frame; The bottom of the frame is equipped with a feeding / discharging motor and a sliding rail, and the casing contains a cover removal circuit board.

[0016] The frame provides a stable support structure for the entire device. The feeding and discharging motors are located at the bottom of the frame, facilitating connection with the transmission components of the feeding and discharging mechanism to achieve automatic feeding and discharging of test tubes. The translation slide rail is also installed at the bottom of the frame, providing a reliable track for the smooth sliding of the tray and ensuring the stability of the test tubes during the feeding and discharging process. The housing encloses the frame and all the mechanisms and components installed on it, providing protection and preventing external factors from interfering with or damaging the internal components of the device. Furthermore, the cap removal circuit board inside the housing receives and sends control signals to achieve precise control of the cap removal motor, thereby completing the automatic opening and closing operation of the test tube caps.

[0017] Furthermore, the lifting mechanism includes a support frame, a lifting belt, a lifting slide rail, a lifting plate, and a rotating shaft. A lifting motor is provided below the support frame, and a second pulley is provided at the output end of the lifting motor. The lifting belt abuts against the second pulley and the rotating shaft respectively. The two ends of the rotating shaft are rotatably connected to the support frame and the connecting plate respectively. The rotating shaft and the lifting plate are threadedly connected. Two side plates are symmetrically provided on both sides of the lifting plate, and the side plates are slidably connected to the lifting slide rail. The frame is provided with connecting plates and support frames from top to bottom. Lifting slide rails are provided on both sides of the frame, and a support plate is provided between the two side plates.

[0018] After the lifting motor starts, the second pulley at its output end begins to rotate. Since the lifting belt abuts against the second pulley and the rotating shaft respectively, the rotation of the second pulley will drive the lifting belt to move, which in turn drives the rotating shaft to rotate. The rotating shaft is threadedly connected to the lifting plate. During the rotation of the rotating shaft, the lifting plate will move up and down along the axial direction of the rotating shaft. The side plates symmetrically arranged on both sides of the lifting plate are slidably connected to the lifting slide rail. The lifting slide rail provides a stable track for the movement of the side plates, making the lifting plate move more smoothly during the up and down movement without shaking or deviation. Through this structural design of the lifting mechanism, the height of components such as the capping mechanism and the clamping mechanism can be easily adjusted. When it is necessary to operate test tubes of different specifications, simply control the operation of the lifting motor to move the lifting plate to the appropriate height, so that the profiling head can accurately abut and separate from the test tube cap, thereby realizing the automatic opening and tightening operation of test tube caps of different specifications, improving the versatility and adaptability of the device.

[0019] Furthermore, the device for automatically opening and closing test tube caps also includes a main circuit board and a display screen, which are electrically connected. The main circuit board is located inside the housing, and the display screen is located outside the housing. The main circuit board needs to be electrically connected to the cover removal circuit board, clamping motor, feeding / discharging motor and lifting motor respectively.

[0020] The main circuit board receives and sends various control signals, which can precisely coordinate the operation of the capping circuit board, clamping motor, feeding and discharging motor, and lifting motor, ensuring that each component operates according to the predetermined program and rhythm. This enables the device to operate the test tube caps automatically and efficiently. Since the display screen is electrically connected to the main circuit board, the operator can clearly understand the current operating status of the device by observing the display screen, such as the operating status of the capping motor, the feeding and discharging progress, and the height position of the lifting mechanism. This facilitates the operator to monitor and operate the device in real time, promptly identify and resolve any potential problems, and ensure the stable operation and efficient functioning of the device.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention achieves automatic opening and tightening of caps on several test tubes through the coordinated operation of the cap removal mechanism, clamping mechanism, feeding and discharging mechanism, lifting mechanism, and the main circuit board and display screen. The device has a high degree of automation, which can significantly improve work efficiency, reduce the labor intensity and error of manual operation, and reduce pollution caused by human labor. Furthermore, due to the reasonable structural design between the various mechanisms, it can ensure the accuracy and stability of the cap removal action, adapt to the cap opening and closing requirements of test tubes of different specifications, and has wide versatility and adaptability.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example: Figures 1-9 As shown, the present invention provides a technical solution: a device that can automatically open and close test tube caps.

[0026] like Figures 1-2 As shown, an automatic test tube cap opening and closing device is used to automatically open and tighten the caps of several test tubes 5. The device includes a cap removal mechanism 1, a clamping mechanism 2, and a feeding and discharging mechanism 3. The cap removal mechanism 1 includes several contour heads 11; The clamping mechanism 2 includes a base plate 27, on which a plurality of placement holes are provided; The feeding and discharging mechanism 3 includes a bottom box 31 and a tray 35. The bottom box 31 is provided with several sets of placement slots, and the bottom box 31 is located above one end of the tray 35. The number of contouring heads 11, test tubes 5, placement holes, and placement slots are matched. Several test tubes 5 are placed in several sets of placement slots in the base box 31, and several contouring heads 11 pass through several sets of placement holes in the base plate 27. The shape of the lower surface of the contouring head 11 matches the shape of the upper surface of the cap of the test tube 5. The contouring head 11 makes the automatic opening and closing of the caps of several test tubes 5 consistent.

[0027] Several test tubes 5 are placed into the placement slots on the bottom box 31. After the test tubes 5 are fixed, the feeding and discharging mechanism 3 realizes the automatic feeding and discharging of the test tubes 5, improving the automation level and working efficiency of the entire device. The tray 35 moves to the bottom of the clamping mechanism 2, thereby causing the bottom box 31 to move the test tubes 5 to the bottom of the capping mechanism 1. The clamping mechanism 2 is used to limit the position of the capping mechanism 1. Since the profiling head 11 passes through the placement hole, the clamping mechanism 2 can drive the profiling head 11 to move up and down. When the test tube 5 moves to the bottom of the profiling head 11, the bottom plate 27 moves downward, driving the profiling head 11 downward until the lower end of the profiling head 11 abuts against the cap of the test tube 5. Then the profiling head 11 is rotated. Through the specific structural design of the profiling head 11 and the cap of the test tube 5, the cap is automatically opened or tightened. Through the coordinated work of various mechanisms, the automatic opening and tightening of the caps of several test tubes 5 is realized, ensuring the consistency of the opening and closing of the test tubes 5, improving working efficiency, reducing the labor intensity and error of manual operation, and reducing pollution caused by human.

[0028] like Figures 4-6 As shown, the cap removal mechanism 1 also includes a cap removal circuit board 12, which is electrically connected to several cap removal motors 13. The output end of the cap removal motor 13 is provided with a pin 14, and the lower outer ring of the pin 14 is provided with a retractable copper sleeve 15. The lower end of the retractable copper sleeve 15 is provided with a contour head 11. When removing the cap: the bottom box 31 is placed below the copying head 11, and the lower surface of the copying head 11 abuts against the cap of the test tube 5.

[0029] After receiving a control signal from the capping circuit board 12, the capping motor 13 starts operating, driving the ejector pin 14 to rotate. This, in turn, drives the retractable copper sleeve 15 below the ejector pin 14 to rotate, further driving the contour head 11 at the lower end of the retractable copper sleeve 15 to rotate. When the lower end of the contour head 11 contacts the cap of the test tube 5, because the shape of the contour head 11 matches the shape of the cap of the test tube 5, the contour head 11 will drive the cap of the test tube 5 to rotate under the rotational force generated by the continuous operation of the capping motor 13. This enables the automatic opening of the bottle cap. If the bottle cap needs to be tightened, the cap removal motor 13 is controlled to run in reverse. Following the reverse process, the contour head 11 drives the bottle cap to rotate in the opposite direction, tightening the bottle cap onto the test tube 5. The entire cap removal process is ensured by the precise control of the cap removal motor 13 by the cap removal circuit board 12, as well as the coordinated cooperation between the telescopic copper sleeve 15, the ejector pin 14, and the contour head 11. This ensures the accuracy and stability of the cap removal action and enables the efficient automatic opening and closing of the bottle cap on the test tube 5.

[0030] like Figures 3-4 As shown, the clamping mechanism 2 also includes a chain 22, a support plate 24, a rotating shaft 25, and a transition plate 26. A clamping motor 21 is provided below the support plate 24. A first sprocket is provided at the output end of the clamping motor 21. A second sprocket is provided on the outer sleeve of the rotating shaft 25. The chain 22 meshes with the first sprocket and the second sprocket respectively. Several tensioning wheels 23 are provided above the support plate 24. Several tensioning wheels 23 abut against the chain 22. The support plate 24 and the rotating shaft 25 are rotatably connected. The rotating shaft 25 and the transition plate 26 are threadedly connected. A base plate 27 is provided above the transition plate 26.

[0031] After the clamping motor 21 is started, the first sprocket at its output end begins to rotate, driving the chain 22 to move. Since the chain 22 is also meshed with the second sprocket, the rotating shaft 25 also rotates with the movement of the chain 22. Several tensioning wheels 23 are used for tensioning, so that the chain 22 and the first and second sprockets are interlocked to prevent slippage during rotation. The rotating shaft 25 is threadedly connected to the transition plate 26. When the rotating shaft 25 rotates, the transition plate 26 moves up and down along the axial direction of the rotating shaft 25. A [something is placed] on top of the transition plate 26. There is a base plate 27, which moves up and down synchronously with the movement of the transition plate 26. The base plate 27 is provided with several sets of placement holes, which are used to stably place the test tube 5. When the base plate 27 moves up and down, it can drive the contour head 11 to move up and down, so that when the feeding and discharging mechanism 3 drives the test tube 5 into and out of the device, the contour head 11 is located at a higher position above the test tube 5, preventing the contour head 11 from interfering with the test tube 5 during the movement of the test tube 5. When the test tube 5 reaches the cap removal station, it drives the contour head 11 to move down until it touches the cap of the test tube 5.

[0032] like Figure 4As shown, the support plate 24 is provided with several sets of upper through holes, and the transition plate 26 is provided with several sets of lower through holes. The positions of the several sets of upper through holes, lower through holes and placement holes are corresponding. The ejector pin 14 passes through the upper through hole, and the retractable copper sleeve 15 passes through the lower through hole.

[0033] The above structure allows the ejector pin 14 and the retractable copper sleeve 15 to rotate freely within the upper and lower through holes, while ensuring their stability and accuracy during movement. When the clamping motor 21 drives the chain 22 to move, which in turn drives the transition plate 26 to move up and down, the ejector pin 14 and the retractable copper sleeve 15 will move synchronously with the transition plate 26, ensuring that the contour head 11 can accurately contact and separate from the cap of the test tube 5, thereby realizing the automatic opening and tightening operation of the cap of the test tube 5.

[0034] like Figure 7 As shown, the feeding and discharging mechanism 3 also includes a feeding and discharging motor 32 and a sliding rail 34. The output end of the feeding and discharging motor 32 is provided with a first pulley, and a feeding and discharging belt 33 is provided on the first pulley. The feeding and discharging belt 33 and the first pulley abut against each other. A connecting member 36 is provided on the feeding and discharging belt 33, and a tray 35 is provided on one side of the connecting member 36. The tray 35 and the sliding rail 34 are slidably connected.

[0035] When the feeding / discharging motor 32 is running, the first pulley at its output end drives the feeding / discharging belt 33 to move. Since a connector 36 is fixed on the feeding / discharging belt 33, the connector 36 moves synchronously with the feeding / discharging belt 33. A tray 35 is connected to one side of the connector 36, and the tray 35 is placed on the translation slide rail 34. Therefore, when the connector 36 moves, it will drive the tray 35 to slide on the translation slide rail 34. A bottom box 31 is set above one end of the tray 35. The bottom box 31 is used to place the test tube 5 to be operated. Through this structural design, the feeding / discharging mechanism 3 can realize the automatic feeding and discharging of the test tube 5. When it is necessary to send the test tube 5 into the device for operation, the feeding / discharging motor 32 rotates forward, driving the tray 35 and the bottom box 31 to move into the device. When the operation is completed, the feeding / discharging motor 32 rotates in reverse, driving the tray 35 and the bottom box 31 to move out of the device, so as to facilitate the removal of the operated test tube 5. This automatic feeding / discharging design improves the automation level and working efficiency of the entire device.

[0036] like Figure 1 As shown, the device that can automatically open and close test tube caps also includes a lifting mechanism 4, a frame 6, and a housing 7. The housing 7 contains the frame 6, and the frame 6 is equipped with the lifting mechanism 4. The bottom of the frame 6 is equipped with a feeding / discharging motor 32 and a sliding rail 34, and the casing 7 is equipped with a cover removal circuit board 12.

[0037] The frame 6 provides a stable support structure for the entire device. The feeding motor 32 is located above the bottom of the frame 6, which facilitates connection with the transmission components of the feeding mechanism 3 to realize the automatic feeding and discharging operation of the test tubes 5. The translation slide rail 34 is also installed above the bottom of the frame 6, providing a reliable track for the smooth sliding of the tray 35 and ensuring the stability of the test tubes 5 during the feeding and discharging process. The housing 7 encloses the frame 6 and the various mechanisms and components installed on it, playing a protective role and preventing external factors from interfering with or damaging the internal parts of the device. Furthermore, the cap removal circuit board 12 installed inside the housing 7 receives and sends control signals to achieve precise control of the cap removal motor 13, thereby completing the automatic opening and closing operation of the caps on the test tubes 5.

[0038] like Figures 8-9 As shown, the lifting mechanism 4 includes a support frame 42, a lifting belt 43, a lifting slide rail 44, a lifting plate 45, and a rotating shaft 47. A lifting motor 41 is provided below the support frame 42. A second pulley is provided at the output end of the lifting motor 41. The lifting belt 43 abuts against the second pulley and the rotating shaft 47 respectively. The two ends of the rotating shaft 47 are rotatably connected to the support frame 42 and the connecting plate 48 respectively. The rotating shaft 47 and the lifting plate 45 are threadedly connected. Two side plates 46 are symmetrically provided on both sides of the lifting plate 45. The side plates 46 are slidably connected to the lifting slide rail 44. The frame 6 is provided with a connecting plate 48 and a support frame 42 from top to bottom. Lifting slide rails 44 are provided on both sides of the frame 6, and a support plate 24 is provided between the two side plates 46.

[0039] After the lifting motor 41 starts, the second pulley at its output end begins to rotate. Since the lifting belt 43 abuts against the second pulley and the rotating shaft 47 respectively, the rotation of the second pulley will drive the lifting belt 43 to move, which in turn will drive the rotating shaft 47 to rotate. The rotating shaft 47 is threadedly connected to the lifting plate 45. During the rotation of the rotating shaft 47, the lifting plate 45 will move up and down along the axial direction of the rotating shaft 47. The side plates 46 symmetrically arranged on both sides of the lifting plate 45 are slidably connected to the lifting slide rail 44. The lifting slide rail 44 provides a stable track for the movement of the side plates 46. This design makes the lifting plate 45 move more smoothly up and down without shaking or shifting. Through this structural design of the lifting mechanism 4, the height of components such as the cap removal mechanism 1 and the clamping mechanism 2 can be easily adjusted. When it is necessary to operate test tubes 5 of different specifications, simply control the lifting motor 41 to move the lifting plate 45 to the appropriate height, so that the contour head 11 can accurately contact and separate from the cap of the test tube 5, thereby realizing the automatic opening and tightening operation of caps of test tubes 5 of different specifications, improving the versatility and adaptability of the device.

[0040] like Figure 1As shown, the device that can automatically open and close test tube caps also includes a main circuit board 8 and a display screen 9. The main circuit board 8 and the display screen 9 are electrically connected. The main circuit board 8 is located inside the housing 7, and the display screen 9 is located outside the housing 7. The main circuit board 8 is electrically connected to the cover removal circuit board 12, the clamping motor 21, the feeding and discharging motor 32, and the lifting motor 41.

[0041] The main circuit board 8 receives and sends various control signals. It can precisely coordinate the operation of the cap removal circuit board 12, the clamping motor 21, the feeding and discharging motor 32, and the lifting motor 41 to ensure that each component operates according to the predetermined program and rhythm. This enables the device to automatically open and close the caps of the test tubes 5 efficiently. Since the display screen 9 is electrically connected to the main circuit board 8, the operator can clearly understand the current operating status of the device by observing the display screen 9, such as the operating status of the cap removal motor 13, the feeding and discharging progress, and the height position of the lifting mechanism 4. This facilitates the operator to monitor and operate the device in real time, promptly identify and resolve any potential problems, and ensure the stable operation and efficient work of the device.

[0042] Working principle of the invention: During operation, the operator first places the test tube 5 to be processed into the bottom box 31 of the feeding / discharging mechanism 3, sets the operating parameters through the display screen 9, and starts the device. The main circuit board 8 immediately sends control commands to each subsystem. The feeding / discharging motor 32 drives the transmission system to accurately transport the test tube 5 to the capping station. The lifting motor 41 automatically adjusts the height of the capping mechanism 1 according to the specifications of the test tube 5 to ensure that the contour head 11 is perfectly aligned with the bottle cap. The clamping motor 21 drives the transition plate 26 to descend through the chain 22, so that the contour head 11 presses against the bottle cap with appropriate pressure. After receiving the positioning signal, the capping circuit board 12... The device immediately controls the cap removal motor 13 to operate at a preset torque and speed. Through the transmission chain of the ejector pin 14, the retractable copper sleeve 15, and the contour head 11, the rotational motion is precisely converted into the opening or closing action of the cap. After the operation is completed, the feeding and discharging mechanism 3 automatically removes the test tube 5 from the device. At the same time, the display screen 9 displays the operation result data.
