The control system includes a panel display switch, as well as a power supply, a five-way valve, a delay controller, and a three-way valve that are electrically connected to the panel display switch. The delay controller is set to send a start signal from its port X seconds after power supply. The five-way valve is used to control the switching of the lifting or lowering state of the piston rod of the cylinder, and the three-way valve is used to control the on-off switching of the rubber barrel pressure supply. This control system has the following working states: State 1: When the panel button is not pressed, the panel display switch is in the OFF state, and the power supply turns on the five-way valve. At this time, the cylinder is in the lifted state, the delay controller has no power supply, and the three-way valve is in the exhaust state; State 2: When the panel button is pressed, the panel display switch is in the ON state, and the power supply disconnects the five-way valve; the power supply turns on the delay controller, and the delay controller starts timing; the five-way valve switches to the lowering process. After a period of time T0 (T0 < X), the cylinder runs to the bottom end, and the rubber path and air path are sealed; after X seconds, the output terminal of the delay controller outputs a voltage to control the opening of the three-way valve, and the rubber barrel starts to be pressurized; State 3: When the panel button is pressed again, the panel display switch switches to the OFF state. At this time, the delay controller loses power, the three-way valve is powered off, the rubber barrel exhausts, the power supply turns on the five-way valve, and the cylinder starts to rise. The upper air path of the rubber barrel is first opened for exhaust, and then the lower end of the rubber barrel disengages from the flow channel.

[0026] Optionally, the panel display switch is provided with a three-color indicator light with a common cathode, including a blue indicator light indicating the power supply of the delay controller, a green indicator light indicating the output of the delay controller, and a red indicator light indicating the five-way valve; In the above State 1, the red indicator light is on when the power supply turns on the five-way valve; In the above State 2, the red indicator light goes out when the power supply disconnects the five-way valve, the blue indicator light is on when the power supply turns on the delay controller, and both the blue indicator light and the green indicator light are on when the three-way valve opens after X seconds; In the above State 3, both the blue indicator light and the green indicator light go out when the delay controller loses power, and the red indicator light is on when the power supply turns on the five-way valve.

[0027] The technical solution of the present invention has the following advantages: 1. This device uses a driver-driven method to remove the old rubber barrel and install a new rubber barrel. The rubber barrel is pushed in and pulled out from the front of the device. The driver drives the rubber barrel drive frame to move up and down to connect or open the air path and the rubber barrel; this device uses an automated method, simplifies the rubber barrel installation procedure, reduces the space required for rubber barrel installation, and has high application value for improving the automation level and production efficiency of the production line.

[0028] 2. The cone-angle Luer connector (a variant of the Luer connector) is used to supply air to the rubber cylinder and maintain the seal at the bottom of the rubber cylinder. Corresponding cone-angle internal holes are made at the top of the rubber cylinder adapter and the head of the flow channel, reducing the required downward pressure of the air cylinder and thus the size and weight of the air cylinder.

[0029] 3. One of the cone-angle Luer connector and the rubber cylinder adapter is made of a softer material. Preferably, the rubber cylinder adapter is made of a soft material to ensure the airtightness of air supply to the rubber cylinder. Similarly, the conical structure of the Luer connector at the head of the flow channel is made of a metal material, which, in combination with the soft material at the bottom of the rubber cylinder, ensures the airtightness of the connection between the bottom of the rubber cylinder and the flow channel.

[0030] 4. The large semi-circular arc structures of the upper bayonet on the rubber cylinder drive frame, the upper bayonet on the support frame, and the upper bayonet on the support base jointly complete the radial positioning and fixation of the rubber cylinder. The rubber cylinder is snapped in from the front using the elasticity of the rubber cylinder, preventing the rubber cylinder from slipping out while positioning it.

[0031] 5. The form of a slide rail cooperating with the support base is adopted to restrain the deflection moment caused by the lateral installation of the actuator (the actuator applies pressure to the edge of the rubber cylinder drive frame close to it, causing a deflection moment of the rubber cylinder drive frame). At the same time, it can ensure that the support base can move longitudinally, facilitating the adjustment of the relative relationship between the flow channel and the piezoelectric valve body. Also, when cleaning the flow channel, the support base can be lifted to facilitate the rotational disassembly of the flow channel.

[0032] 6. A card slot is set on the side of the slide rail, and a spring clamping mechanism (a return spring and a locking block) is set on the back of the support base. After the support base is lifted (to meet the height for flow channel disassembly), the locking block snaps into the card slot of the slide rail to lock the support base and keep it in the lifted state. After cleaning the flow channel, the support base is unlocked by pressing the reset button.

[0033] 7. A spring plunger is installed at the top of the rubber cylinder drive frame. The height of the spring plunger can be adjusted up and down to ensure sufficient pressure is applied to the rubber cylinder when pressing down to maintain the seal between the rubber cylinder and the flow channel. At the same time, when the air cylinder is lifted, it ensures that the upper Luer interface disengages first, releasing the internal pressure of the rubber cylinder first to avoid residual glue flowing out from the lower interface of the rubber cylinder.

[0034] 8. A flat anti-rotation air cylinder is adopted to reduce the size and weight while ensuring no rotational movement.

[0035] 9. The air cylinder piston rod and the rubber cylinder drive frame are fixed by a double-nut clamping method, which can appropriately adjust the running position of the rubber cylinder drive frame. Description of the Drawings

[0054] Please refer to Figure 1, an embodiment of the present invention provides a rapid automatic replacement device for a rubber cylinder, including a rubber cylinder adapter 2, a rubber cylinder driving frame 3, a driver 6, a rubber cylinder radial positioning mechanism, a gas supply sealing joint 4, and a runner outer sealing joint 7.

[0055] Please refer to Figure 2 and Figure 3 , the rubber cylinder adapter 2 is detachably connected to the upper end of the rubber cylinder 1. There is a jack 21 on the rubber cylinder adapter 2, and the jack 21 penetrates the upper and lower surfaces of the rubber cylinder adapter 2. After the upper end of the rubber cylinder 1 is connected to the rubber cylinder adapter 2, the air inlet at the upper end of the rubber cylinder 1 communicates with the jack 21.

[0056] Specifically, the bottom of the rubber cylinder adapter 2 is provided with a T-shaped groove 22, and the T-shaped groove 22 penetrates to the side of the rubber cylinder adapter 2, preferably penetrating two opposite places on the side. The upper end of the rubber cylinder 1 has a flat connecting ear 1a, and the connecting ear and the cylinder body of the rubber cylinder 1 together form a T shape. The T-shaped groove 22 allows the connecting ear at the upper end of the rubber cylinder 1 to be inserted radially and translated.

[0057] Further, the inner side wall of the T-shaped groove 22 is an arc with the center of the jack 21 as the center of the circle, and this arc conforms to the rotation trajectory of the upper end of the rubber cylinder 1 (i.e., the connecting ear 1a) in the T-shaped groove 22; after the connecting ear at the upper end of the rubber cylinder 1 enters the T-shaped groove 22, rotate the rubber cylinder 90° around the central axis of the rubber cylinder 1 itself. At this time, the connecting ear can be supported by the T-shaped groove 22, and rotating the rubber cylinder 90° again can make the connecting ear move out of the T-shaped groove 22 along the radial direction of the rubber cylinder 1.

[0058] Please refer to Figure 1 , the rubber cylinder driving frame 3 has an inner cavity 31, the bottom of the rubber cylinder driving frame 3 is opened with a first opening 32, and at least the front side of the rubber cylinder driving frame 3 is provided with a second opening 33. Preferably, second openings 33 are provided on both the front and rear sides of the rubber cylinder driving frame 3; the upper end of the rubber cylinder 1 passes through the first opening 32 and is located in the inner cavity 31, and the rest of the rubber cylinder 1 is located below the first opening 32; the rubber cylinder adapter 2 is located in the inner cavity 31, and the rubber cylinder adapter 2 can be completely located in the inner cavity 31, and the front and rear ends of the rubber cylinder adapter 2 can also extend out of the rubber cylinder driving frame 3 through the second opening 33; the bottom wall of the inner cavity 31 of the rubber cylinder driving frame 3 is adapted to fit the bottom surface of the rubber cylinder adapter 2, and a fillet is provided at the bottom edge of the rubber cylinder adapter 2, and an arc surface matching the fillet is provided on the inner cavity 31 wall of the rubber cylinder driving frame 3. The positioning of the rubber cylinder adapter 2 is achieved through the cooperation of the fillet and the arc surface. The bottom wall of the inner cavity 31 can support the rubber cylinder adapter 2, that is, when the rubber cylinder driving frame 3 moves upward, it can support the rubber cylinder adapter 2 through the bottom wall of the inner cavity 31 and move upward together; there is a space in the inner cavity 31 of the rubber cylinder driving frame 3 for the rubber cylinder adapter 2 to move a certain distance along the height direction of the rubber cylinder 1; Please refer to Figure 1 and Figure 2, two planes 23 opposite to each other in position are provided on the side surface of the cartridge adapter 2, and the planes 23 cooperate with the side wall of the inner cavity 31 of the cartridge driving frame 3 and can slide relative to each other along the axial direction of the cartridge 1; when actually installing the cartridge 1, the cartridge 1 is translated into the inner cavity 31 through the second opening 33 from the front side of the cartridge driving frame 3; when actually disassembling the cartridge 1, the upper end of the cartridge 1 is translated out of the inner cavity 31 from the second opening 33.

[0059] Please refer to Figure 1 , the driver 6 includes a main body 61 and a moving part 62. The position of the main body 61 is fixed relative to the cartridge 1 after installation and positioning. The moving part 62 is connected to the cartridge driving frame 3, and the moving part 62 is used to drive the cartridge driving frame 3 to move along the axial direction of the cartridge 1. Specifically, the driver 6 uses a power cylinder, such as an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder; the power cylinder preferably uses a flat anti-rotation pneumatic cylinder, which can not only reduce the size and weight but also ensure non-rotating motion; the main body 61 of the pneumatic cylinder is the housing part of the pneumatic cylinder, and the moving part 62 of the pneumatic cylinder is the piston rod. Please refer to Figure 4 , the piston rod penetrates through the cartridge driving frame 3, and two nuts 9 are screwed on the piston rod to clamp the cartridge driving frame 3. This double-nut 9 clamping method can appropriately adjust the relative position between the cartridge driving frame 3 and the piston rod, so as to adjust the running position of the cartridge driving frame 3.

[0060] Please refer to Figure 4 , the air supply sealing joint 4 is fixed to the top of the cartridge driving frame 3. The air supply sealing joint 4 penetrates into the inner cavity 31 from the outer top wall of the cartridge driving frame 3. The jack 21 on the cartridge adapter 2 is directly below the bottom of the air supply sealing joint 4. The air supply sealing joint 4 is used for plugging and mating with the jack 21; specifically, the air supply sealing joint 4 is a tapered Luer joint, and the jack 21 is a corresponding tapered inner hole. The material of the air supply sealing joint 4 is designed to be different from the hardness of the inner wall material of the jack 21 to improve the sealing performance of the fit. The upper and lower ends of the traditional cartridge do not use Luer joint sealing, and the area of the plug-in fit between the cartridge end and the joint is large. The sealing pressure is equal to the fit area multiplied by the pressure. The larger the fit area, the greater the air cylinder pressure required; after changing to the Luer joint, the fit area is reduced, and the requirement for the air cylinder pressure can be reduced.

[0061] Please refer to Figure 1 , the outer sealing joint 7 of the flow channel is located directly below the cartridge 1 and is fixed relative to the driver 6, and is suitable for plugging and mating with the glue outlet at the lower end of the cartridge 1. Specifically, a support base 8 is fixed to the side of the piezoelectric valve body 16 of the dispenser. The support base 8 is located below the cartridge driving frame 3 and above the outer sealing joint 7 of the flow channel. The main body 61 of the driver 6 is fixed to the support base 8; a pivot seat 81 is formed at the bottom of the support base 8, and a detachable shaft rod 18 is provided on the pivot seat as a pivot shaft. The detachable method preferably uses a threaded connection method. The piezoelectric valve flow channel module 17 of the dispenser is pivotally connected to the bottom of the support base 8 through the shaft rod 18; specifically, please refer to Figure 5and Figure 4 A protrusion structure 171 is provided on the top of the piezoelectric valve channel module 17 . A positioning hole 172 is provided on the protrusion structure. The shaft rod 18 is passed through the positioning hole. The shaft rod is pivotally connected to the pivot seat 81 .

[0062] Please refer to Figure 5 and Figure 6 The piezoelectric valve channel module 17 has a nozzle 19, most of which is located inside the piezoelectric valve channel module 17, and a small part is exposed from the bottom of the piezoelectric valve channel module 17; the piezoelectric valve body 16 has a striker (the striker is a basic component structure of the piezoelectric valve, which belongs to the prior art), the striker extends from its bottom and extends into the nozzle 19 of the piezoelectric valve channel module 17, the center axis of the striker coincides with the center axis of the nozzle 19, and the piezoelectric valve channel module 17 can rotate around the striker; a movable part 161 is provided between the bottom of the piezoelectric valve body 16 and the top of the piezoelectric valve channel module 17, the striker passes through the movable part and then extends into the nozzle 19, a guide structure and a spring reset structure are provided between the movable part and the bottom of the piezoelectric valve body 16, and the guide structure is a plug-in matching structure of the guide rod and the guide groove The spring return structure is a structure in which both ends of the spring respectively press against the movable part 161 and the piezoelectric valve body 16, and the movable part can move up and down relative to the piezoelectric valve body 16, that is, move along the axial direction of the striker; a card block 1611 is provided on the movable part, and a corresponding card slot is provided on the piezoelectric valve channel module 17, and the positions of the card block and the card slot are interchangeable. For example, a card slot is provided on the movable part, and a card block is provided on the piezoelectric valve channel module 17, as long as the following functions can be achieved: when the piezoelectric valve channel module 17 rotates around the striker, the card block can be inserted into the card slot (this is the working state), and when the piezoelectric valve channel module 17 is reversed, the card block is removed from the card slot (this is the non-working state for disassembling the piezoelectric valve channel module 17 to clean the channel), and a handle 1612 that can be moved up and down can also be provided on the side of the movable block (see Figure 6 ), the handle can be used to prevent the piezoelectric valve channel module 17 from being moved out of the slot, and when the channel needs to be cleaned, the handle can be pulled open to disassemble the piezoelectric valve channel module 17 normally.

[0063] When the force of the cylinder acts downward on the piezoelectric valve channel module 17 through the rubber tube, since the piezoelectric valve channel module 17 has a tendency to rotate around the shaft 18, the piezoelectric valve channel module 17 has an upward force on the movable part, and the movable part can move upward relative to the piezoelectric valve body 16, so the force of the cylinder will not be directly transmitted to the piezoelectric valve body 16.

[0064] The flow channel outer sealing joint 7 is protrudingly arranged on the piezoelectric valve flow channel module 17, and a conical inner hole 71 is arranged in the flow channel outer sealing joint 7 (please refer to Figure 8 ), which is suitable for matching with the rubber outlet at the lower end of the rubber cylinder 1, and the material of the flow channel outer sealing joint 7 is designed to be harder than that of the rubber cylinder 1 to improve the sealing effect when the two are matched.

[0065] Please refer toFigure 9 , the rubber cylinder radial positioning mechanism includes at least two bayonets 5 distributed along the axial direction of the rubber cylinder 1. When installing the rubber cylinder 1, the rubber cylinder 1 is radially inserted into the bayonet 5, and when removing the rubber cylinder 1, the rubber cylinder 1 radially exits the bayonet 5. Preferably, the bayonet 5 is provided at the first opening 32 and the support base 8. A support frame 10 can also be provided on the main body 61 of the driver 6, and the bayonet 5 is also provided on the support frame 10. The openings of all the bayonets 5 face the same direction for the rubber cylinder 1 to be inserted or removed; the bayonet 5 is a large semi-circular arc structure, and the arc length of the bayonet 5 is greater than 1 / 2 of the circumference and less than 3 / 4 of the circumference, so as to use the elasticity of the rubber cylinder 1 to insert the rubber cylinder 1 into the bayonet 5, positioning the rubber cylinder 1 and preventing the rubber cylinder 1 from slipping out.

[0066] Further, please refer to Figure 1 , a pressing mechanism 11 for pressing the rubber cylinder adapter 2 against the upper end of the rubber cylinder 1 is connected to the top of the rubber cylinder drive frame 3. The pressing mechanism 11 can be a spring or a spring plunger or a rubber pad. A spring plunger is preferably used, and two threaded holes are symmetrically provided on the top of the rubber cylinder drive frame 3 with respect to the air supply sealing joint 4. A spring plunger is screwed into each threaded hole so that the spring plunger can adjust the up and down height, and the internal spring tension of the spring plunger can also be adjusted, so as to ensure that sufficient pressure is applied to the rubber cylinder 1 when pressing down to maintain the seal between the rubber cylinder 1 and the flow channel. At the same time, when the air cylinder is lifted (i.e., when the rubber cylinder is disassembled), the air supply sealing joint 4 first disengages from the rubber cylinder 1, ensuring that the upper Luer interface disengages first, releasing the internal pressure of the rubber cylinder 1 first, and avoiding the residual glue from flowing out from the lower interface of the rubber cylinder 1.

[0067] Further, please refer to Figure 1 , a slide rail 12 is fixed to the piezoelectric valve body 16 on the side facing the rubber cylinder 1. The length direction of the slide rail 12 is parallel to the axis direction of the rubber cylinder 1. The above-mentioned support base 8 and support frame 10 are both slidably connected to the slide rail 12. The slide rail 12 is a dovetail slide rail, and limit screws 20 are provided at both the upper and lower ends to prevent the moving object on the slide rail 12 from disengaging from the slide rail 12 at the upper and lower ends of the slide rail 12.

[0068] Further, please refer to Figure 4 and Figure 10 , a locking mechanism is provided between the support base 8 and the slide rail 12. The function of the locking mechanism is: when the support base 8 moves along the slide rail 12 to a specified height, the support base 8 is locked. The locking mechanism includes a card slot 121, a return spring 13, a return button 15 and a locking block 14. The card slot 121 is provided on the slide rail 12, and the return spring 13, the return button 15 and the locking block 14 are provided on the support base 8. When the support base 8 moves and does not reach the specified position, the locking block 14 is located outside the card slot 121 and moves along the side of the slide rail 12. When the support base 8 moves to the specified position, the locking block 14 is pushed into the card slot 121 by the return spring 13. The return button 15 is used to push the locking block 14, squeezing and compressing the return spring 13 to make the locking block 14 disengage from the card slot 121.

[0069] Specifically, the support base 8 is provided with a groove 82 on the side facing the slide rail 12, and the locking block 14 is inserted into the groove. For example, the locking block 14 is turned right (this direction is reference Figure 4 When the direction Figure 10 When the locking block 14 enters the card slot 121 to the right, the reset spring 13 will also push the reset button 15 to the right, so that the reset button 15 will pop out of the support base 8.

[0070] The replacement process of the rubber cartridge 1 of the above-mentioned rubber cartridge rapid automatic replacement device is as follows: 1. Install the rubber cartridge adapter 2 on the upper end of the rubber cartridge 1; 2. When the pressure supply of rubber cylinder 1 is removed, the cylinder piston rod is raised by controlling the cylinder air pressure; 3. The rubber cartridge 1 and the rubber cartridge adapter 2 are pushed into the rubber cartridge drive frame 3 from the front end, and the side wall of the rubber cartridge 1 is snapped into the bayonet 5; 4. By controlling the air pressure of the cylinder, lower the cylinder piston rod and press the Luer interfaces at both ends of the rubber cylinder 1 to maintain air tightness; 5. After the air supply of rubber cartridge 1 is turned on, it works normally until the glue inside rubber cartridge 1 is used up; 6. Control the air pressure of the cylinder and raise the piston rod of the cylinder. First, the upper Luer joint of the rubber cylinder 1 is separated, and then the lower Luer joint of the rubber cylinder 1 is separated; 7. Pull out the rubber cartridge 1 assembly forward, replace it with a new one, and then reinstall it.

[0071] After replacing the rubber cartridge 1, the flow channel needs to be cleaned. The process of cleaning the flow channel is as follows: 1. Take out the rubber cylinder 1 forward, control the air pressure of the cylinder, and lower the piston rod of the cylinder (consider the upper space problem); 2. Remove the shaft 18 between the piezoelectric valve channel module 17 and the support base 8; 3. Lift the support base 8, the support base 8 together with the cylinder and the rubber tube 1. The support base 8 is locked after reaching the limit position, and the reset button 15 pops out; 4. Rotate the piezoelectric valve flow channel module 17 to separate the piezoelectric valve flow channel module 17 from the piezoelectric valve body 16 so as to clean the flow channel; 5. After the flow channel is cleaned, reinstall the piezoelectric valve flow channel module 17, press the reset button 15 to release the locking mechanism, and reinstall the shaft 18; 6. Install the new rubber cartridge and perform normal operation.

[0072] In summary, the rapid automatic replacement device for the rubber cartridge proposed by the present invention has the following advantages: 1. The device uses a driver-driven method to remove the old rubber cartridge and install the new rubber cartridge. The rubber cartridge 1 is pushed in and pulled out from the front of the device, and the driver 6 drives the rubber cartridge drive frame 3 to move up and down to connect or open the air circuit and the rubber cartridge 1. The device uses an automated method, which simplifies the installation procedure of the rubber cartridge 1 and reduces the space required for the installation of the rubber cartridge 1. It has a high use value for improving the automation level of the production line and improving production efficiency.

[0073] 2. A conical Luer connector (a modified Luer connector) is used to supply air to the rubber cartridge 1 and to maintain the seal of the bottom of the rubber cartridge 1. Corresponding conical inner holes 71 are made at the top of the rubber cartridge adapter 2 and the head of the flow channel, which reduces the downward force requirement of the cylinder and can reduce the size and weight of the cylinder.

[0074] 3. One of the conical Luer connector and the rubber cartridge adapter 2 is made of a softer material, and preferably the rubber cartridge adapter 2 is made of a soft material to ensure the air tightness of the rubber cartridge 1. Similarly, the conical structure of the Luer connector at the head of the flow channel is made of metal, which cooperates with the soft material at the bottom of the rubber cartridge 1 to ensure the air tightness of the connection between the bottom of the rubber cartridge 1 and the flow channel.

[0075] 4. The semicircular arc structure of the bayonet 5 on the rubber cartridge driving frame 3, the semicircular arc structure of the bayonet 5 on the support frame 10, and the semicircular arc structure of the bayonet 5 on the support base 8 together complete the radial positioning and fixation of the rubber cartridge 1.

[0076] 5. The slide rail 12 is used in conjunction with the support base 8 to constrain the deflection torque caused by the lateral installation of the driver 6 (the driver 6 applies pressure to the rubber cartridge drive frame 3 near the side edge to cause the rubber cartridge drive frame 3 to generate a deflection torque), while ensuring that the support base 8 can move in the longitudinal direction, which is convenient for adjusting the relative relationship between the flow channel and the piezoelectric valve body. At the same time, when the flow channel is cleaned, the support base 8 can be moved up to facilitate the rotation and disassembly of the flow channel.

[0077] 6. A clamping groove 121 is arranged on the side of the slide rail 12, and a spring clamping mechanism (return spring 13 and locking block 14) is arranged on the back of the support base 8. After the support base 8 is lifted (to meet the height for removing the flow channel), the locking block 14 is snapped into the clamping groove 121 of the slide rail 12, so as to lock the support base 8 and keep the support base 8 in the lifted state. After cleaning the flow channel, by pressing the reset button 15, the support base 8 is unlocked.

[0078] An embodiment of the present invention further provides a control system adopting the above-mentioned rubber barrel rapid automatic replacement device. In combination with the above-mentioned rubber barrel rapid automatic replacement device, a set of control system is required to control the replacement process of the rubber barrel.

[0079] The control system uses a cylinder as a driver and mainly completes the following functions: 1. It can respectively adjust and display the pressure of the supply rubber barrel and the pressure of the cylinder; 2. It can realize the air supply and air stop sequences conforming to normal operation; Please refer to Figure 11 , the control system includes a panel display switch, and a power supply, a five-way valve, a delay controller and a three-way valve electrically connected to the panel display switch. The delay controller is set to send a start signal from the port X seconds after power supply. The five-way valve is used to control the lifting or lowering state switching of the piston rod of the cylinder, and the three-way valve is used to control the on-off switching of the pressure supply of the rubber barrel 1.

[0080] Specifically, the panel display switch is a self-locking single-pole double-throw switch with red, blue and green three-color LED indicators (common cathode). Among them, the blue indicator indicates the power supply of the delay controller, the green indicator indicates the output of the delay controller, and the red indicator indicates the five-way valve; the power supply is 24V, the power supply is connected to an AC / DC converter through a switch, and the AC / DC converter is connected to the delay controller, the first air pressure sensor and the second air pressure sensor; the air source interface is connected to the five-way valve, the cylinder pressure regulating valve, the throttle valve and the cylinder to realize the regulation of the air supply volume of the cylinder and the switching of the cylinder action; the air source interface is connected to the rubber barrel pressure regulating valve, the three-way valve and the rubber barrel, and the internal air pressure of the rubber barrel is controlled by controlling the air inlet at the top of the rubber barrel.

[0081] The control system has the following working states: State 1, when the panel button is not pressed, the panel display switch is in the OFF state, the power supply is connected to the five-way valve, and the red indicator is on. At this time, the cylinder is in the lifted state, the delay controller has no power supply, and the three-way valve is in the exhaust state; State 2: When the panel button is pressed, the panel display switch is in the ON state. The power supply disconnects the five-way valve, and the red indicator light goes out. The power supply connects to the power supply terminal of the delay controller, the blue indicator light is on, and the delay controller starts timing. The five-way valve switches to the downward process. After a period of T0 (T0 < X), the cylinder runs to the bottom end, and the glue path and air path are sealed. After X time, the output terminal of the delay controller outputs a voltage to control the three-way valve to open. At this time, the green indicator light is on (both the blue and green indicator lights are on), and the glue cylinder starts to supply pressure. State 3: When the panel button is pressed again, the panel display switch switches to the OFF state. At this time, the delay controller loses power, and both the blue and green indicator lights go out. The three-way valve is powered off, the glue cylinder exhausts, the power supply connects to the five-way valve, the red indicator light is on, and the cylinder starts to rise. Since the upper air path Luer connector is opened first during the first half of the upward movement of the cylinder to accelerate exhaust, when the cylinder rises to the point where the glue path is separated, the exhaust process is over, there is no pressure inside the glue cylinder, and the residual glue will not overflow. Then the cylinder continues to rise until the lower end of the glue cylinder completely disengages from the flow channel.

[0082] The following is the control system state switching process table:

[0083] The following is the control system indicator light color correspondence table:

[0084] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
