Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging equipment technology, specifically relating to an automated packaging equipment. Background Technology
[0002] Solder paste is a paste made from soft solder powder, flux, and binder, used for connecting microelectronic devices. Its core function is to melt and fill gaps at the joint upon heating, forming a reliable connection. Through optimized composition and processes, efficient and precise brazing connections are achieved, making it widely used in precision manufacturing and high-temperature engineering. Its properties simplify the welding of complex structures while ensuring high joint reliability.
[0003] During the production and processing of solder paste, it needs to be packaged into various packaging containers using packaging equipment for sealing. Due to its certain stickiness, the part that comes into contact with the inner wall of the hopper can easily adhere to the hopper of the packaging equipment, resulting in a certain amount of residue. This part of the paste is inconvenient to use and also affects the convenience of cleaning the hopper later. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide an automated dispensing device that can shake off residual paste adhering to the inner wall of the hopper and drop it to the bottom of the hopper, making it convenient to utilize this portion of paste and also facilitating subsequent cleaning of the inside of the multi-functional storage hopper.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated dispensing device, including a support platform, a support rod mounted on the top of the support platform, a first support ring plate mounted on the top of the support rod, a buffer device connected to the inner side of the first support ring plate, the other end of the buffer device connected to a second support ring plate, a multi-functional storage hopper fixedly mounted on the inner side of the second support ring plate, a spiral guide plate mounted on the inner side of the multi-functional storage hopper, a warm water containing jacket jointly provided on the inner side of the multi-functional storage hopper and the inner side of the spiral guide plate, a first support frame connected to the side of the first support ring plate, a second motor mounted on the top of the first support frame, the output end of the second motor connected to an eccentric wheel, a telescopic cavity also provided on the top of the first support frame, a telescopic rod inserted and connected to the inner side of the telescopic cavity and provided with a spring, a toggle plate sleeved on the outer side of the telescopic rod, one end of the telescopic rod connected to a hammer ball, a second support frame mounted on the top of the support platform, a heating circulation device mounted on the top of the second support frame, and a dispensing quantitative extrusion mechanism connected to the bottom of the support platform.
[0006] The beneficial effects of this utility model are as follows: When using this device, after injecting the paste-like brazing filler metal to be dispensed into the multi-functional storage hopper through the filling pipe interface, the operation of the electric heating tube and water pump can be controlled. The electric heating tube heats the water inside the heating chamber to maintain a temperature of about 40 degrees Celsius. The water pump pumps the warm water from the heating chamber and delivers it into the warm water receiving jacket inside the multi-functional storage hopper. The warm water receiving jacket covers the paste inside the multi-functional storage hopper, providing uniform heat preservation and preventing the paste from solidifying and hardening, which would prevent it from flowing downwards. The spiral guide plate not only guides the paste to flow downwards but also increases the area of the warm water in the warm water receiving jacket acting on the paste inside the multi-functional storage hopper, providing better heat preservation.
[0007] To prevent excessive residue of paste from adhering to the inner wall of the multi-functional storage hopper, a second motor drives an eccentric wheel to rotate. This eccentric wheel, along with a sliding actuating plate and telescopic rod, causes the telescopic rod to retract into the telescopic cavity, compressing the spring. When the protruding end of the eccentric wheel leaves the actuating plate, the spring's rebound force pushes the telescopic rod rapidly towards the multi-functional storage hopper, causing the hammer ball to strike the hopper. This vibration, generated by the compression and rebound of the spring-hydraulic damper, is achieved through the first and second universal joints. The spring-hydraulic damper can rotate freely in the direction of the hopper's vibration without affecting its movement. The vibration of the hopper shakes off any residual paste adhering to its inner wall, causing it to fall to the bottom and enter the bellows, facilitating its utilization and subsequent cleaning.
[0008] As a further improvement to the above technical solution: the buffer device includes a first universal joint connected to the first support ring plate, one end of the first universal joint being connected to a spring hydraulic damper, one end of the spring hydraulic damper being connected to a second universal joint, and the other end of the second universal joint being connected to the second support ring plate.
[0009] Because of the first and second universal joints, the spring hydraulic damper can rotate arbitrarily with the vibration direction of the multi-functional storage hopper without affecting the movement of the multi-functional storage hopper.
[0010] To avoid the arching effect preventing the cream from flowing smoothly downwards:
[0011] As a further improvement to the above technical solution: a first motor is mounted on the top of the multifunctional storage hopper via a motor bracket, and the output end of the first motor is connected to a rotary paddle via a coupling.
[0012] The beneficial effects of this improvement are: by driving the rotary paddle to rotate through the first motor, the paste inside the multi-functional storage hopper is agitated, thus avoiding the inability of the paste to flow smoothly downwards due to the arching effect.
[0013] As a further improvement to the above technical solution: the side of the multi-functional storage hopper is provided with a first connecting joint and a second connecting joint.
[0014] As a further improvement to the above technical solution: the top of the multifunctional storage hopper is provided with a filling pipe interface.
[0015] The filling pipe interface is the channel through which materials are filled into the multi-functional storage hopper.
[0016] To circulate and heat the water:
[0017] As a further improvement to the above technical solution: the heating circulation device includes a heating chamber, an electric heating tube is installed on the inner side of the heating chamber, and a return port and a water pump are provided on the side of the heating chamber. A delivery hose is connected between the return port and the second connecting joint, and between the water pump and the first connecting joint.
[0018] The beneficial effects of this improvement are as follows: the water inside the heating chamber is heated by an electric heating tube to maintain a temperature of about 40 degrees Celsius. The warm water in the heating chamber is pumped out by a water pump and delivered into the warm water receiving jacket inside the multi-functional storage hopper. The water circulates back and forth between the heating chamber and the warm water receiving jacket. The water that enters the warm water receiving jacket flows back into the heating chamber for reheating through the delivery hose between the second connecting joint and the return interface.
[0019] For the packaging of solder paste:
[0020] As a further improvement to the above technical solution: the dispensing and quantitative extrusion mechanism includes a first one-way valve connected to a bellows, the bottom of the first one-way valve being connected to a three-way pipe, a connecting bracket being sleeved on the outside of the three-way pipe, the top of the connecting bracket being fixed to the bottom of the support platform, a second one-way valve being connected to one end of the three-way pipe, one end of the second one-way valve being connected to an extrusion pipe, and a cylinder being connected to one end of the three-way pipe, with the piston rod end of the cylinder being connected to a piston.
[0021] The beneficial effects of this improvement are as follows: When dispensing the paste, the piston is driven by the cylinder to slide towards the cylinder. Under negative pressure, the first one-way valve opens, and the paste in the bellows is sucked into the three-way tube under negative pressure, filling the space between the piston and the second one-way valve inside the three-way tube. Then, the paste can be extruded and dispensed. The piston is driven by the cylinder to move towards the second one-way valve. Under pressure, the second one-way valve opens, and the paste enters the extrusion tube and is output to the container to be dispensed.
[0022] To ensure that the connection between the multi-functional storage hopper and the first one-way valve is not affected when it is subjected to hammering vibration:
[0023] As a further improvement to the above technical solution: a bellows is connected between the bottom of the multifunctional storage hopper and the first one-way valve.
[0024] The beneficial effect of this improvement is that the bellows design ensures that the connection between the multi-functional storage hopper and the first one-way valve is not affected when the hopper is subjected to hammering vibration.
[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0034] like Figures 1-6 As shown, an automated dispensing device includes a support platform 1, a support rod 2 mounted on the top of the support platform 1, a first support ring plate 3 mounted on the top of the support rod 2, a buffer device connected to the inner side of the first support ring plate 3, and the other end of the buffer device connected to a second support ring plate 4. A multi-functional storage hopper 8 is fixedly provided on the inner side of the second support ring plate 4, and a spiral guide plate 9 is provided on the inner side of the multi-functional storage hopper 8. A warm water containing jacket 10 is provided on the inner side of both the multi-functional storage hopper 8 and the spiral guide plate 9. A first... The first support frame 17 has a second motor 18 mounted on its top. The output end of the second motor 18 is connected to an eccentric wheel 19. The top of the first support frame 17 is also provided with a telescopic cavity 20. A telescopic rod 21 is inserted and connected to the inner side of the telescopic cavity 20 and a spring 22 is provided. A toggle plate 23 is sleeved on the outer side of the telescopic rod 21. One end of the telescopic rod 21 is connected to a hammer ball 24. The top of the support platform 1 is provided with a second support frame 25. The top of the second support frame 25 is provided with a heating circulation device. The bottom of the support platform 1 is connected to a dispensing and quantitative extrusion mechanism.
[0035] When using this device, the paste-like brazing filler metal to be dispensed is injected into the multi-functional storage hopper 8 through the filling pipe interface 16. Then, the electric heating tube 27 and water pump 29 are controlled to operate. The electric heating tube 27 heats the water inside the heating chamber 26 to maintain a temperature of about 40 degrees Celsius. The water pump 29 pumps the warm water out of the heating chamber 26 and delivers it into the warm water receiving jacket 10 inside the multi-functional storage hopper 8. The warm water receiving jacket 10 covers the paste inside the multi-functional storage hopper 8, providing uniform heat preservation and preventing the paste from solidifying and hardening, which would prevent it from flowing downwards. The spiral guide plate 9 guides the paste downwards while increasing the contact area of the warm water in the warm water receiving jacket 10 on the paste inside the multi-functional storage hopper 8, providing better heat preservation.
[0036] To prevent excessive residue of paste from adhering to the inner wall of the multi-functional storage hopper 8, the second motor 18 can be controlled to drive the eccentric wheel 19 to rotate. The eccentric wheel 19 then moves the actuating plate 23, along with the telescopic rod 21, causing the telescopic rod 21 to retract into the telescopic cavity 20, compressing the spring 22. When the protruding end of the eccentric wheel 19 leaves the actuating plate 23, the spring 22 rebounds, pushing the telescopic rod 21 rapidly toward the multi-functional storage hopper 8. This causes the hammer ball 24 to strike the multi-functional storage hopper 8, causing the multi-functional storage hopper to... Vibration is generated by the compression and rebound of the spring hydraulic damper 6. Due to the presence of the first universal joint 5 and the second universal joint 7, the spring hydraulic damper 6 can rotate arbitrarily with the vibration direction of the multi-functional storage hopper 8 without affecting the movement of the multi-functional storage hopper 8. Through the vibration of the multi-functional storage hopper 8, the residual paste adhering to the inner wall of the multi-functional storage hopper 8 can be shaken off and fall to the bottom of the multi-functional storage hopper 8 into the bellows 31, making it convenient to utilize this part of the paste and also convenient for subsequent cleaning of the inside of the multi-functional storage hopper 8.
[0037] The buffer device includes a first universal joint 5 connected to the first support ring plate 3, one end of the first universal joint 5 being connected to a spring hydraulic damper 6, one end of the spring hydraulic damper 6 being connected to a second universal joint 7, and the other end of the second universal joint 7 being connected to the second support ring plate 4.
[0038] Because of the first universal joint 5 and the second universal joint 7, the spring hydraulic damper 6 can rotate arbitrarily with the vibration direction of the multi-functional storage hopper 8 without affecting the movement of the multi-functional storage hopper 8.
[0039] The top of the multi-functional storage hopper 8 is equipped with a first motor 13 via a motor bracket, and the output end of the first motor 13 is connected to the rotary paddle 15 via a coupling 14.
[0040] The first motor 13 drives the rotary paddle 15 to rotate, which agitates the paste inside the multi-functional storage hopper 8, preventing the paste from not flowing smoothly downwards due to the arching effect.
[0041] The side of the multi-functional storage hopper 8 is provided with a first connecting joint 11 and a second connecting joint 12.
[0042] The top of the multi-functional storage hopper 8 is provided with a filling pipe interface 16.
[0043] The filling pipe interface 16 is the channel for filling materials into the multi-functional storage hopper 8.
[0044] The heating circulation device includes a heating chamber 26, an electric heating tube 27 is installed on the inner side of the heating chamber 26, and a return port 28 and a water pump 29 are provided on the side of the heating chamber 26. A delivery hose 30 is connected between the return port 28 and the second connecting joint 12, and between the water pump 29 and the first connecting joint 11.
[0045] The water inside the heating chamber 26 is heated by the electric heating tube 27 to maintain a temperature of about 40 degrees Celsius. The warm water in the heating chamber 26 is pumped out by the water pump 29 and sent into the warm water receiving jacket 10 inside the multi-functional storage hopper 8. The water circulates back and forth between the heating chamber 26 and the warm water receiving jacket 10. The water that enters the warm water receiving jacket 10 flows back into the heating chamber 26 for reheating through the conveying hose 30 between the second connecting joint 12 and the return interface 28.
[0046] The dispensing and quantitative extrusion mechanism includes a first one-way valve 32 connected to a bellows 31. The bottom of the first one-way valve 32 is connected to a three-way pipe 33. A connecting bracket is sleeved on the outside of the three-way pipe 33. The top of the connecting bracket is fixed to the bottom of the support platform 1. A second one-way valve 34 is connected to one end of the three-way pipe 33. One end of the second one-way valve 34 is connected to an extrusion pipe 35. A cylinder 36 is connected to one end of the three-way pipe 33. The piston rod end of the cylinder 36 is connected to a piston 37.
[0047] When dispensing the paste, the piston 37 is driven by the cylinder 36 to slide towards the cylinder 36. Under negative pressure, the first one-way valve 32 opens, and the paste in the bellows 31 is sucked into the three-way pipe 33 under negative pressure, filling the space between the piston 37 and the second one-way valve 34 inside the three-way pipe 33. Then, the paste can be extruded for dispensing. The piston 37 is driven by the cylinder 36 to move towards the second one-way valve 34. Under pressure, the second one-way valve 34 is opened, and the paste enters the extrusion pipe 35 and is output to the container to be dispensed.
[0048] A bellows 31 is connected between the bottom of the multifunctional storage hopper 8 and the first one-way valve 32.
[0049] The bellows 31 ensures that the multi-functional storage hopper 8 will not be affected by the hammering vibration when it is connected to the first one-way valve 32.
[0050] The working principle and usage process of this utility model are as follows: When using this device, the paste-like solder to be dispensed is injected into the multi-functional storage hopper 8 through the filling pipe interface 16. Then, the electric heating tube 27 and water pump 29 are controlled to operate. The electric heating tube 27 heats the water inside the heating chamber 26, maintaining it at approximately 40 degrees Celsius. The water pump 29 pumps the warm water from the heating chamber 26 and delivers it into the warm water receiving jacket 10 inside the multi-functional storage hopper 8. The warm water receiving jacket 10 coats the paste inside the multi-functional storage hopper 8, providing uniform heat preservation and preventing the paste from solidifying and hardening, thus preventing it from flowing downwards. The spiral guide plate 9 guides the paste downwards. At the same time, the increased warm water in the warm water receiving jacket 10 has a greater effective contact area with the paste inside the multi-functional storage hopper 8, providing better heat preservation. The water circulates back and forth between the heating chamber 26 and the warm water receiving jacket 10. The water entering the warm water receiving jacket 10 flows back into the heating chamber 26 for reheating through the delivery hose 30 between the second connecting joint 12 and the return port 28. When dispensing the paste, the piston 37 is driven by the cylinder 36 to slide towards the cylinder 36. Under negative pressure, the first one-way valve 32 opens, and the paste in the bellows 31 is drawn into the three-way pipe 33 under negative pressure, filling the space between the piston 37 and the second one-way valve 34 inside the three-way pipe 33. Then, the paste can be extruded and dispensed. The piston 37 is driven by cylinder 36 to move toward the second one-way valve 34. Under pressure, the second one-way valve 34 is opened, and the paste enters the extrusion tube 35 and is output to the container to be dispensed. By controlling the stroke of cylinder 36, the amount of paste output each time can be controlled to achieve quantitative dispensing. To avoid a large amount of paste adhering and remaining on the inner wall of the multi-functional storage hopper 8, the second motor 18 can be controlled to drive the eccentric wheel 19 to rotate. The eccentric wheel 19 moves the actuating plate 23 and the telescopic rod 21 to slide, causing the telescopic rod 21 to retract into the telescopic cavity 20 and compress the spring 22. When the protruding end of the eccentric wheel 19 leaves the actuating plate 23, the spring 22 rebounds and pushes the telescopic rod 21 toward the direction of the extrusion tube 35. The material moves rapidly towards the multi-functional storage hopper 8, causing the hammer ball 24 to strike the hopper. This causes the hopper to vibrate due to the compression and rebound of the spring-hydraulic damper 6. Because of the first universal joint 5 and the second universal joint 7, the spring-hydraulic damper 6 can rotate freely in the direction of vibration of the hopper without affecting its movement. The vibration of the hopper shakes off residual paste adhering to its inner wall, causing it to fall to the bottom and enter the bellows 31 for easy utilization and subsequent cleaning. The first motor 13 drives the rotary paddle 15 to rotate.The paste inside the multi-functional storage hopper 8 is agitated to prevent it from being unable to flow smoothly downwards due to the arching effect.
