[0030] Another object of the present invention is to provide a control system that employs the above-mentioned rapid automatic rubber cylinder replacement device, wherein the driver is a cylinder. 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 cylinder pressure supply. This control system has the following working states:

[0031] State 1: When the panel button is not pressed, the panel display switch is in the OFF state. 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;

[0032] 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; the power supply turns on the delay controller, and the delay controller starts timing; the five-way valve switches to the downward process. After a period of time T0 (T0 < X), the cylinder runs to the bottom end, and the rubber path airtightness is completed; after X seconds, the output terminal of the delay controller outputs a voltage to control the three-way valve to open, and the rubber cylinder starts to supply pressure;

[0033] 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 cylinder exhausts, the power supply turns on the five-way valve, and the cylinder starts to rise. The upper air path of the rubber cylinder is first opened for exhaust, and then the lower end of the rubber cylinder disengages from the flow channel.

[0034] 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;

[0035] In the said State 1, the red indicator light is on when the power supply turns on the five-way valve;

[0036] In the said 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;

[0037] In the said 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.

[0038] The technical solution of the present invention has the following advantages:

[0039] 1. This device uses a driver-driven method to remove the old rubber cartridge and install the new rubber cartridge. The rubber cartridge is pushed in and pulled out from the front of the device, and the driver drives the rubber cartridge drive frame up and down to connect or open the air circuit and the rubber cartridge. This device uses an automated method, which simplifies the rubber cartridge installation procedure and reduces the space required for rubber cartridge installation. It has high practical value in improving the automation level of the production line and improving production efficiency.

[0040] 2. A tapered Luer connector (a variant of the Luer connector) is used to supply air to the cartridge and maintain the seal at the bottom of the cartridge. Corresponding tapered inner holes are made at the top of the cartridge adapter and the head of the flow channel, reducing the downward force required for the cylinder and reducing the size and weight of the cylinder.

[0041] 3. One of the tapered Luer connector and the cartridge adapter should be made of a softer material. It is preferred that the cartridge adapter be made of a soft material to ensure the air tightness of the cartridge air supply. Similarly, the tapered structure of the Luer connector at the head of the flow channel is made of metal, which, combined with the soft material at the bottom of the cartridge, ensures the air tightness of the connection between the bottom of the cartridge and the flow channel.

[0042] 4. The large semi-circular arc structure of the bayonet on the rubber cylinder drive frame, the large semi-circular arc structure of the bayonet on the support frame, and the large semi-circular arc structure of the bayonet on the support base jointly complete the radial positioning and fixation of the rubber cylinder; the elasticity of the rubber cylinder is used to clamp the rubber cylinder from the front, positioning it while preventing it from slipping out.

[0043] 5. The slide rail is combined with the support base to constrain the deflection torque caused by the lateral installation of the driver (the driver applies pressure to the rubber cartridge drive frame near the side edge to generate a deflection torque for the rubber cartridge drive frame). At the same time, it can ensure that the support base 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 cleaning the flow channel, the support base can be moved upward to facilitate the rotation and disassembly of the flow channel.

[0044] 6. Set a slot on the side of the slide rail and a spring clamping mechanism (reset spring and locking block) on the back of the support base. After the support base moves up (to meet the flow channel disassembly height), the locking block is locked into the slot of the slide rail, which can lock the support base and keep it in the raised state. After cleaning the flow channel, press the reset button to unlock the support base.

[0045] 7. A spring plunger is installed on the top of the rubber cartridge drive frame. The spring plunger can be adjusted up and down to ensure that sufficient pressure is applied to the rubber cartridge to maintain the seal between the rubber cartridge and the flow channel when pressing down. At the same time, when the cylinder is lifted, ensure that the upper Luer interface is disengaged first to release the internal pressure of the rubber cartridge first and prevent residual rubber from flowing out of the lower interface of the rubber cartridge.

[0046] 8. Use flat anti-rotation cylinder to reduce size and weight while ensuring no rotational motion.

[0047] 9. The cylinder piston rod and the rubber barrel drive frame are fixed by a double-nut clamping method, and the running position of the rubber barrel drive frame can be adjusted appropriately. Brief Description of the Drawings

[0066] 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 drive frame 3, a driver 6, a rubber cylinder radial positioning mechanism, a gas supply and sealing joint 4, and a runner outer sealing joint 7.

[0067] 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 is communicated with the jack 21.

[0068] 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 horizontally along the radial direction.

[0069] Furthermore, 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 its own central axis. 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.

[0070] Please refer to Figure 1 , the rubber cylinder drive frame 3 has an inner cavity 31. The bottom of the rubber cylinder drive frame 3 is opened with a first opening 32, and at least the front side of the rubber cylinder drive 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 drive 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. 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 drive frame 3 through the second opening 33; the bottom wall of the inner cavity 31 of the rubber cylinder drive frame 3 is adapted to fit the bottom surface of the rubber cylinder adapter 2, and the bottom edge of the rubber cylinder adapter 2 is provided with a fillet. There is an arc surface on the inner cavity wall of the rubber cylinder drive frame 3 that cooperates with this fillet to realize the positioning of the rubber cylinder adapter 2. The bottom wall of the inner cavity 31 can support the rubber cylinder adapter 2, that is, when the rubber cylinder drive 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 drive 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. The plane 23 cooperates with the inner wall of the inner cavity 31 of the cartridge driving frame 3 and can slide relatively 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.

[0071] 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 shell 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 passes 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.

[0072] 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 conical Luer joint, and the jack 21 is a corresponding conical 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 cartridge end plugged and mated with the joint is large. The sealing pressure is equal to the mating area multiplied by the pressure. The larger the mating area, the greater the air cylinder pressure required; after changing to the Luer joint, the mating area is reduced, and the required air cylinder pressure can be reduced.

[0073] 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 outlet of 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 dispensing machine. 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 dispensing machine 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 , and a positioning hole 172 is provided on the protrusion structure. The above-mentioned shaft rod 18 is passed through the positioning hole, and the shaft rod is pivotally connected to the pivot seat 81 .

[0074] Please refer to Figure 5 and Figure 6 The piezoelectric valve flow channel module 17 has a nozzle 19, most of which is located inside the piezoelectric valve flow channel module 17, and a small part is exposed from the bottom of the piezoelectric valve flow channel module 17; the piezoelectric valve body 16 has a striker (the striker is the basic component structure of the piezoelectric valve and belongs to the prior art), the striker extends from its bottom and extends into the nozzle 19 of the piezoelectric valve flow channel module 17, the central axis of the striker coincides with the central axis of the nozzle 19, and the piezoelectric valve flow 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 flow channel module 17, the striker passes through the movable part and extends into the nozzle 19, and a guide structure and a spring return 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 the two 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 clamping block 1611 is provided on the movable part, and a corresponding clamping groove is provided on the piezoelectric valve flow channel module 17. The positions of the clamping block and the clamping groove are interchangeable. For example, a clamping groove is provided on the movable part and a clamping block is provided on the piezoelectric valve flow channel module 17. As long as the following functions can be achieved: when the piezoelectric valve flow channel module 17 rotates around the striker, the clamping block can be clamped into the clamping groove (this is the working state), and when the piezoelectric valve flow channel module 17 is reversed, the clamping block is removed from the clamping groove (this is the non-working state for disassembling the piezoelectric valve flow channel module 17 to clean the flow channel). A handle 1612 that can be toggled 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. When the channel needs to be cleaned, the handle can be pulled open and the piezoelectric valve channel module 17 can be disassembled normally.

[0075] 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 exerts 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.

[0076] The flow channel outer sealing joint 7 is protrudingly provided on the piezoelectric valve flow channel module 17, and a tapered inner hole 71 is provided in the flow channel outer sealing joint 7 (see Figure 8 ), which is suitable for matching the rubber outlet at the lower end of the rubber cylinder 1, the material of the flow channel outer sealing joint 7 is designed to be harder than the material of the rubber cylinder 1 to improve the sealing effect when the two are matched.

[0077] Please refer toFigure 9 , the cartridge radial positioning mechanism includes at least two bayonets 5 distributed along the axial direction of the cartridge 1. When installing the cartridge 1, the cartridge 1 is radially snapped into the bayonet 5, and when removing the cartridge 1, the cartridge 1 radially disengages from the bayonet 5. Preferably, the bayonet 5 is provided at the first opening 32 and on 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 to facilitate the insertion or removal of the cartridge 1; 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 of the circle and less than 3 / 4 of the circumference of the circle, so as to use the elasticity of the cartridge 1 to snap the cartridge 1 into the bayonet 5, positioning the cartridge 1 and preventing the cartridge 1 from slipping out.

[0078] Further, please refer to Figure 1 , a pressing mechanism 11 for pressing the cartridge adapter 2 against the upper end of the cartridge 1 is connected to the top of the cartridge driving frame 3. The pressing mechanism 11 can adopt a spring or a spring plunger or a rubber pad, preferably a spring plunger. Two threaded holes are symmetrically arranged on the top of the cartridge driving frame 3 with respect to the air supply sealing joint 4, and a spring plunger is screwed into each threaded hole so that the spring plunger can adjust the up and down height, and the spring tension inside the spring plunger can also be adjusted, so as to ensure that sufficient pressure is given to the cartridge 1 when pressing down to maintain the seal between the cartridge 1 and the flow channel. At the same time, when the air cylinder is lifted (i.e., when the cartridge is disassembled), the air supply sealing joint 4 first disengages from the cartridge 1, ensuring that the upper Luer interface disengages first, releasing the internal pressure of the cartridge 1 first, and avoiding the residual glue from flowing out from the lower interface of the cartridge 1.

[0079] Further, please refer to Figure 1 , a slide rail 12 is fixed to the side of the piezoelectric valve body 16 facing the cartridge 1. The length direction of the slide rail 12 is parallel to the axis direction of the cartridge 1. The above-mentioned support base 8 and support frame 10 are both slidably connected to the slide rail 12. The slide rail 12 adopts 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 upper and lower ends of the slide rail 12.

[0080] 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 disengage the locking block 14 from the card slot 121.

[0081] 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 placed in the groove. For example, the locking block 14 is turned right (this direction is reference Figure 4 When the direction, if the reference Figure 10 When the locking block 14 enters the slot 121 to the right, it will also push the reset button 15 to the right, causing the reset button 15 to pop out of the support base 8.

[0082] The replacement process of the rubber cartridge 1 of the above-mentioned rubber cartridge rapid automatic replacement device is as follows:

[0083] 1. Install the rubber cartridge adapter 2 on the upper end of the rubber cartridge 1;

[0084] 2. When the pressure supply of rubber cylinder 1 is removed, the cylinder piston rod is raised by controlling the cylinder pressure;

[0085] 3. Push the rubber cartridge 1 and the rubber cartridge adapter 2 into the rubber cartridge drive frame 3 from the front end, and snap the side wall of the rubber cartridge 1 into the bayonet 5;

[0086] 4. By controlling the air pressure in the cylinder, lower the cylinder piston rod and tighten the Luer connectors at both ends of the rubber cylinder 1 to maintain air tightness;

[0087] 5. After the air supply of rubber cylinder 1 is turned on, it works normally until the glue inside rubber cylinder 1 is used up;

[0088] 6. Control the air pressure in the cylinder and raise the piston rod. First, the upper Luer connector of the rubber cylinder 1 will separate, and then the lower Luer connector of the rubber cylinder 1 will separate.

[0089] 7. Pull out the rubber cartridge 1 assembly forward, replace it with a new one, and then reinstall it.

[0090] After replacing the rubber cartridge 1, the flow channel needs to be cleaned. The process of cleaning the flow channel is as follows:

[0091] 1. Take out the rubber cylinder 1 forward, control the air pressure in the cylinder, and lower the piston rod of the cylinder (consider the upper space problem);

[0092] 2. Remove the shaft 18 between the piezoelectric valve flow channel module 17 and the support base 8;

[0093] 3. Lift the support base 8, the cylinder and the rubber tube 1 together. The support base 8 is locked after reaching the limit position, and the reset button 15 pops out.

[0094] 4. Rotate the piezoelectric valve flow channel module 17 to separate the piezoelectric valve flow channel module 17 from the piezoelectric valve body 16 to clean the flow channel;

[0095] 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;

[0096] 6. Install the new rubber cartridge and perform normal operation.

[0097] In summary, the rapid and automatic replacement device for the rubber cartridge proposed in the present invention has the following advantages:

[0098] 1. This 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. This 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 high practical value in improving the automation level of the production line and enhancing production efficiency.

[0099] 2. A tapered Luer connector (a modified Luer connector) is used to supply air to the cartridge 1 and maintain a seal at the bottom of the cartridge 1. Corresponding tapered inner holes 71 are made at the top of the cartridge adapter 2 and the head of the flow channel, reducing the downward force required for the cylinder and thus reducing the size and weight of the cylinder.

[0100] 3. One of the tapered Luer connector and the cartridge adapter 2 is made of a softer material. Preferably, the cartridge adapter 2 is made of a soft material to ensure the air tightness of the gas supply of the cartridge 1. Similarly, the tapered structure of the Luer connector at the head of the flow channel is made of metal, which, combined with the soft material at the bottom of the cartridge 1, ensures the air tightness of the connection between the bottom of the cartridge 1 and the flow channel.

[0101] 4. The large semicircular arc structure of the bayonet 5 on the rubber cylinder driving frame 3, the large semicircular arc structure of the bayonet 5 on the support frame 10, and the large semicircular arc structure of the bayonet 5 on the support base 8 jointly complete the radial positioning and fixation of the rubber cylinder 1.

[0102] 5. The form of using the slide rail 12 in cooperation with the support base 8 is adopted to restrain the deflection moment caused by the lateral installation of the driver 6 (the driver 6 applies pressure to the glue barrel driving frame 3 near the side edge, causing the glue barrel driving frame 3 to generate a deflection moment), and at the same time, it can ensure that the support base 8 can move longitudinally, facilitating the adjustment of the relative relationship between the flow channel and the piezoelectric valve body. At the same time, when cleaning the flow channel, the support base 8 can be lifted to facilitate the rotary disassembly of the flow channel.

[0103] 6. A clamping groove 121 is arranged on the side of the slide rail 12, and a spring clamping mechanism (a return spring 13 and a locking block 14) is arranged on the back of the support base 8. After the support base 8 is lifted (to meet the disassembly height of the flow channel), the locking block 14 is clamped into the clamping groove 121 of the slide rail 12, and the support base 8 can be locked to maintain the lifted state of the support base 8. After cleaning the flow channel, by pressing the reset button 15, the support base 8 can be unlocked.

[0104] The embodiment of the present invention also provides a control system adopting the above glue barrel rapid automatic replacement device. In combination with the above glue barrel rapid automatic replacement device, a set of control system is required to control the replacement process of the glue barrel.

[0105] The control system uses a cylinder as the driver and mainly completes the following functions:

[0106] 1. It can respectively adjust and display the pressure of the supply glue barrel and the pressure of the cylinder;

[0107] 2. It can realize the gas supply and gas stop sequences that conform to normal working conditions;

[0108] Please refer to Figure 11 , 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 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 glue barrel 1.

[0109] 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, a pressure sensor one, and a pressure sensor two; 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 adjustment of the air supply volume to the cylinder and the switching of the cylinder action; the air source interface is connected to the glue barrel pressure regulating valve, the three-way valve, and the glue barrel to control the internal air pressure of the glue barrel by controlling the air inlet at the top of the glue barrel.

[0110] The control system has the following working states:

[0111] State 1: When the panel button is not pressed, the panel display switch is in the OFF state, the power is connected to the five-way valve, the red indicator light is on, the cylinder is in the lifting state, the delay controller has no power supply, and the three-way valve is in the exhaust state;

[0112] State 2: When the panel button is pressed, the panel display shows the switch is in the ON state, the power is disconnected from the five-way valve, and the red indicator light goes out; the power is connected to the power supply end of the delay controller, the blue indicator light turns on, and the delay controller starts timing; the five-way valve switches to the descending process, and in a period of time T0 (T0 <X)后,气缸运行到底端,胶路气路密封完成;X时间后,延时控制器输出端输出电压控制三通阀打开,此时绿色指示灯亮(蓝色和绿色指示灯均亮),胶筒开始供压;

[0113] State three, when the panel button is pressed again, the panel display switch switches to the OFF state, the delay controller loses power, the blue and green indicators are off, the three-way valve is powered off, the rubber cylinder is exhausted, the power is connected to the five-way valve, the red indicator light is on, and the cylinder begins to rise. Since the upper air path Luer interface is opened first in the first half of the cylinder's ascent, exhaust is accelerated. When the cylinder rises to the point where the glue path is separated, the exhaust process is over, there is no pressure inside the rubber cylinder, and residual glue will not overflow; then the cylinder continues to rise until the lower end of the rubber cylinder is completely out of the flow channel.

[0114] The following is a table of the control system state switching process:

[0115]
