Description

Technical Field

[0001] This invention belongs to the field of flux filling technology, specifically an automatic filling mechanism suitable for high-activity flux. Background Technology

[0002] High-activity flux is a flux with a stronger or higher proportion of activators in its formulation. Its core function is to efficiently remove oxide films and significantly improve solder wetting and spreading capabilities, even when metal surfaces are heavily oxidized or components have poor solderability, thereby ensuring reliable and fast soldering. To facilitate precise application and dispensing on production lines or at repair stations, high-activity flux is typically packaged into multiple small-capacity bottles after production for subsequent transport and storage.

[0003] Patent CN215797164U discloses an automatic flux filling mechanism suitable for wave soldering. The mechanism includes a housing, with support rods fixedly connected to both sides of the inner top wall of the housing. The bottom ends of the two support rods are fixedly connected to the same bearing. The outer ring of the bearing is fixedly connected to the support rod, and a material container is fixedly connected to the inner side of the bearing's inner ring. A gear ring is connected to the bottom of the material container via a key. A motor is fixedly connected to one side of the inner top wall of the housing, and a rotating rod is fixedly connected to the bottom of the motor's output shaft. This patent, by incorporating a motor, allows the bottled flux to be inverted and placed in the material container after the cap is removed during flux filling. Starting the motor causes the gear ring to rotate, thus rotating the material container. The rotation of the material container causes the bottled flux to experience centrifugal force, creating a swirling flow within the bottle and allowing the flux to flow out more quickly.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] When filling the bottle with highly active flux, the worker needs to manually place the bottle with the opening facing upwards at the filling equipment and align it with the discharge port. Then, the filling equipment is turned on to fill the bottle with flux.

[0006] However, when there are a large number of bottles to be filled, this manual placement significantly increases the labor intensity of workers. In addition, even if a conveyor line can be used to transport multiple bottles to the filling equipment instead of workers, when multiple bottles move on the conveyor line, they may tip over or pile up, making it difficult to ensure that the bottle mouth of each bottle is aligned with the discharge port, thus affecting the filling effect. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes an automatic filling mechanism suitable for high-activity flux.

[0009] The bottle orientation assembly includes a baffle, a lifting plate, and two bottle-holding plates. The two bottle-holding plates are symmetrically distributed on both sides above the conveyor belt. One edge of the bottle-holding plate is attached to one end face of the lifting plate, and the other edge is attached to the baffle. A limit rod is fixedly connected to one side of the bottom of the bottle-holding plate.

[0011] Preferably, a slider is fixedly connected to one end of the bottle-holding plate, and one end of the slider is slidably disposed on the lifting plate. Two cylinders are symmetrically fixedly connected to the upper surface of the lifting plate, and the piston ends of the two cylinders are respectively fixedly connected to the ends of the two sliders.

[0012] Preferably, both ends of the baffle are fixedly connected to connecting rods, and the end of the connecting rod away from the baffle is slidably connected to the edge of the lifting plate.

[0013] Preferably, a cylinder is fixedly connected to one side of the lifting plate, and the piston end of the cylinder is fixedly connected to one end of the connecting rod.

[0014] Preferably, a vibrating plate is slidably mounted on the bottle-holding plate, two guide rods are fixedly connected to one side of the vibrating plate, a fixed plate is fixedly connected to one end of the bottle-holding plate, the guide rods are slidably mounted on the fixed plate, a second cylinder is fixedly connected to one side of the fixed plate, and the piston end of the second cylinder is fixedly connected to one side of the vibrating plate.

[0015] Preferably, a vision sensor is provided on one side of the upper end of the frame. The vision sensor is located below the filling head and is used to detect bottles that have reached below the filling head.

[0016] Preferably, the baffle is provided with a bottle-dispensing assembly;

[0017] The bottle-dispensing assembly includes a support base and a lever. One end of the lever is rotatably mounted on the support base, and one side of the support base is fixedly connected to a baffle.

[0018] Preferably, a motor is fixedly connected to the upper end of the support base, and the output end of the motor is fixedly connected to one end of the lever.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The automatic filling mechanism for high-activity flux described in this invention utilizes a bottle orientation component. Multiple bottles are placed within a frame structure formed by a baffle, a lifting plate, and two bottle-holding plates. The bottles then move sequentially to the filling head with their openings facing upwards, eliminating the need for manual handling and placement of bottles by workers, significantly reducing labor intensity. Furthermore, compared to directly conveying multiple bottles to the filling equipment via a conveyor line, this solution organizes the previously disorganized bottles into a linear arrangement with their openings facing upwards and precisely aligned with the filling head. This prevents bottles from tipping over or piling up on the conveyor line, which could cause misalignment of the bottle openings and affect the filling effect.

[0021] 2. The automatic filling mechanism for high-activity flux described in this invention utilizes a bottle-dispensing assembly. During the conveying process, a dispensing lever rotates regularly back and forth. If a bottle stands upright with its opening facing down above the bottle channel, when the bottle reaches the baffle, it will contact the rotating dispensing lever. The dispensing lever will then push the bottle to both sides, causing the bottle to move away from the top of the bottle channel and contact the vibrating plate again until it can smoothly enter the bottle channel. This avoids the situation where some bottles stand upright with their openings facing down above the bottle channel, causing the bottles in the bottle channel to push the bottle along the top of the bottle channel, resulting in the bottle and subsequent bottles being stuck, thus affecting the smooth progress of subsequent filling work.

[0033] The technical solution of the present invention will now be clearly and completely described 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.

[0034] Please refer to Figures 1-9 The present invention provides a technical solution: an automatic filling mechanism suitable for high-activity flux, including a filling machine body 2 and a frame 1. A conveyor belt 15 is provided on the frame 1. A filling head 7 is provided at the bottom of the filling machine body 2. The filling head 7 is aligned with the center line of the conveyor belt 15. The filling machine body 2 is fixedly connected to a fixed frame 13. The fixed frame 13 is located on one side of the frame 1 and includes a bottle body orientation component.

[0035] The bottle orientation assembly includes a baffle 8, a lifting plate 4, and two bottle placement plates 5. The two bottle placement plates 5 are symmetrically distributed on both sides above the conveyor belt 15. One edge of the bottle placement plate 5 is attached to one end face of the lifting plate 4, and the other edge is attached to the baffle 8. A limit rod 24 is fixedly connected to one side of the bottom of the bottle placement plate 5. The baffle 8, the lifting plate 4, and the two bottle placement plates 5 cooperate with each other to form a frame structure.

[0036] In this embodiment, as Figures 2-5 , Figures 7-9As shown, the device includes a support column 3, a lifting plate 4 with one end slidably mounted on the support column 3, a threaded rod 17 threadedly connected to one end of the lifting plate 4, both ends of the threaded rod 17 being rotatably mounted on the support column 3, a motor 23 fixedly connected to one end of the support column 3, and the output end of the motor 23 being fixedly connected to one end of the threaded rod 17.

[0037] A slider 21 is fixedly connected to one end of the bottle plate 5. One end of the slider 21 is slidably mounted on the lifting plate 4. Two cylinders 20 are symmetrically fixedly connected to the upper surface of the lifting plate 4. The piston ends of the two cylinders 20 are fixedly connected to the ends of the two sliders 21 respectively.

[0038] Both ends of the baffle 8 are fixedly connected to connecting rods 9, and the end of the connecting rod 9 away from the baffle 8 is slidably connected to the edge of the lifting plate 4.

[0039] A cylinder 10 is fixedly connected to one side of the lifting plate 4, and the piston end of the cylinder 10 is fixedly connected to one end of the connecting rod 9.

[0040] A vibrating plate 6 is slidably inserted on the bottle-holding plate 5. Two guide rods 11 are fixedly connected to one side of the vibrating plate 6. A fixing plate 22 is fixedly connected to one end of the bottle-holding plate 5. The guide rods 11 are slidably inserted on the fixing plate 22. A cylinder 12 is fixedly connected to one side of the fixing plate 22. The piston end of the cylinder 12 is fixedly connected to one side of the vibrating plate 6.

[0041] A vision sensor 14 is provided on one side of the upper end of the frame 1. The vision sensor 14 is located below the filling head 7 and is used to detect bottles that have reached below the filling head 7.

[0042] Specifically, in the existing technology, when filling the bottle with highly active flux, the worker needs to manually place the bottle with the bottle opening facing upwards at the filling equipment and align it with the discharge port, and then turn on the filling equipment to fill the bottle with flux.

[0043] However, when there are a large number of bottles to be filled, this manual placement significantly increases the labor intensity of workers. In addition, even if a conveyor line can be used to transport multiple bottles to the filling equipment instead of workers, when multiple bottles move on the conveyor line, they may tip over or pile up, making it difficult to ensure that the bottle mouth of each bottle is aligned with the discharge port, thus affecting the filling effect.

[0044] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0045] This solution is applied in a single application to fill multiple bottles of the same specification within the same batch with highly active flux. These bottles are not sealed before filling; the main body of the bottle is cylindrical, with its length exceeding its diameter, and the bottle opening has multiple raised threads for subsequent connection to the internal threads of the bottle cap.

[0046] The vertical section at the bottom of the two bottle-holding plates 5 serves as the bottle channel. Depending on the bottle diameter, two cylinders 20 drive two sliders 21 to slide simultaneously towards or away from each other, adjusting the distance between the two bottle-holding plates 5 and thus controlling the width of the bottle channel to match the bottle diameter. When multiple bottles are placed between the two bottle-holding plates 5, they slide down the inner cavity of the bottle-holding plates 5 under gravity and converge into the bottle channel. Because the bottle width matches the bottle diameter, the bottle can only enter the bottle channel when its bottom is facing down. Conversely, if the bottle opening is facing up or the bottle is laid flat, the protruding threads at the bottle opening will prevent the bottle from smoothly entering the bottle channel. Therefore, all bottles entering the bottle channel have their openings facing upwards. Furthermore, after the bottle enters the frame structure, cylinder 212 drives the vibrating plate 6 to move back and forth, causing the bottle in the frame structure to vibrate, thereby causing multiple bottles to continuously change their posture until they can fall smoothly into the bottle channel. Also, depending on the height of the bottle, motor 23 drives the threaded rod 17 to rotate, causing the lifting plate 4 to rise and fall, so that the bottom of the bottle in the bottle channel is in contact with the surface of the conveyor belt 15, and the bottle mouth is flush with the top of the bottle channel.

[0047] Subsequently, cylinder 10 is used to drive baffle 8 to rise and fall, adjusting the distance between the lower edge of baffle 8 and the surface of conveyor belt 15, so that the distance is equal to the height of the bottle.

[0048] Because the bottle bottom is in contact with the surface of the conveyor belt 15, the conveyor belt 15 can move the bottle body. Multiple bottles located in the bottle channel pass under the baffle 8 sequentially and are arranged between the two limiting rods 24. When the bottle reaches below the filling head 7, the vision sensor 14 detects the bottle. The conveyor belt 15 then stops, the filling machine body 2 starts, and flux is injected into the bottle through the filling head 7. The bottle is then removed from under the filling head 7. Repeating this process allows multiple bottles to move sequentially to the filling head 7 with their openings facing upwards for filling, eliminating the need for workers to manually pick up the bottles and place them at the filling head 7, significantly reducing the labor intensity of workers. In addition, compared to the process of directly transporting multiple bottles to the filling equipment via a conveyor line, this solution can organize the originally messy and disordered multiple bottles into a linear arrangement, with the bottle mouths facing upwards and precisely aligned with the filling head 7. This avoids the bottle mouths not being aligned with the discharge port due to tilting and piling up when multiple bottles move on the conveyor line, thus affecting the filling effect.

[0049] In this embodiment, as Figure 6 As shown, the baffle 8 is equipped with a bottle-dispensing assembly;

[0050] The bottle-dispensing assembly includes a support base 16 and a lever 18. One end of the lever 18 is rotatably mounted on the support base 16, and one side of the support base 16 is fixedly connected to the baffle 8.

[0051] A motor 19 is fixedly connected to the upper end of the support base 16, and the output end of the motor 19 is fixedly connected to one end of the lever 18.

[0052] Specifically, in the above embodiments, although multiple bottles can be brought into the bottle channel by vibration, when the bottle is standing above the bottle channel with its mouth facing down, the bottle will not be affected by the vibrating plate 6. When the bottle in the bottle channel moves, it will be pushed to move along the top of the bottle channel. When the bottle reaches the baffle 8, the bottle is blocked by the baffle 8 and pushed by the subsequent bottles, which causes the bottle and the subsequent bottles to be stuck and unable to move further, thus affecting the smooth progress of the subsequent filling work.

[0053] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0054] During the conveying process, motor 19 drives lever 18 to rotate regularly back and forth. Since the lower surface of lever 18 is flush with the lower surface of baffle 8, when the height of baffle 8 is adjusted, lever 18 is also at a suitable height. When a bottle in the bottle channel moves to baffle 8, it will not contact lever 18. If a bottle stands upright above the bottle channel with its opening facing down, it will contact the rotating lever 18 when it reaches baffle 8. Lever 18 will then push the bottle to both sides, moving it away from the top of the bottle channel and allowing it to contact vibrating plate 6 again until it can smoothly enter the bottle channel. This avoids the situation where some bottles stand upright with their openings facing down, causing other bottles in the channel to move along the top of the channel, resulting in the bottle and subsequent bottles getting stuck and affecting the smooth progress of subsequent filling.

[0055] Working principle: The vertical section at the bottom of the two bottle-holding plates 5 serves as the bottle channel. Based on the bottle diameter, two cylinders 20 drive two sliders 21 to slide simultaneously towards or away from each other, adjusting the distance between the two bottle-holding plates 5 and thus controlling the width of the bottle channel to match the bottle diameter. When multiple bottles are placed between the two bottle-holding plates 5, they slide down the inner cavity of the bottle-holding plates 5 under gravity and converge into the bottle channel. Because the bottle width matches the bottle diameter, the bottle can only enter the bottle channel when its bottom is facing down. Conversely, if the bottle opening is facing up or the bottle is laid flat, the protruding threads at the bottle opening will prevent the bottle from smoothly entering the bottle channel. Therefore, all bottles entering the bottle channel have their openings facing upwards. Furthermore, after the bottle enters the frame structure, cylinder 212 drives the vibrating plate 6 to move back and forth, causing the bottle in the frame structure to vibrate, thereby causing multiple bottles to continuously change their posture until they can fall smoothly into the bottle channel. Also, depending on the height of the bottle, motor 23 drives the threaded rod 17 to rotate, causing the lifting plate 4 to rise and fall, so that the bottom of the bottle in the bottle channel is in contact with the surface of the conveyor belt 15, and the bottle mouth is flush with the top of the bottle channel.

[0056] Subsequently, cylinder 10 is used to drive baffle 8 to rise and fall, adjusting the distance between the lower edge of baffle 8 and the surface of conveyor belt 15, so that the distance is equal to the height of the bottle.

[0057] Because the bottle bottom is in contact with the surface of the conveyor belt 15, the conveyor belt 15 can move the bottle body. Multiple bottles located in the bottle channel pass under the baffle 8 sequentially and are arranged between the two limiting rods 24. When the bottle reaches below the filling head 7, the vision sensor 14 detects the bottle. The conveyor belt 15 then stops, the filling machine body 2 starts, and flux is injected into the bottle through the filling head 7. The bottle is then removed from under the filling head 7. Repeating this process allows multiple bottles to move sequentially to the filling head 7 with their openings facing upwards for filling, eliminating the need for workers to manually pick up the bottles and place them at the filling head 7, significantly reducing the labor intensity of workers. In addition, compared to the process of directly transporting multiple bottles to the filling equipment via a conveyor line, this solution can organize the originally messy and disordered multiple bottles into a linear arrangement, with the bottle mouths facing upwards and precisely aligned with the filling head 7. This avoids the bottle mouths not being aligned with the discharge port due to tilting and piling up when multiple bottles move on the conveyor line, thus affecting the filling effect.

[0058] During the conveying process, motor 19 drives lever 18 to rotate regularly back and forth. Since the lower surface of lever 18 is flush with the lower surface of baffle 8, when the height of baffle 8 is adjusted, lever 18 is also at a suitable height. When a bottle in the bottle channel moves to baffle 8, it will not contact lever 18. If a bottle stands upright above the bottle channel with its opening facing down, it will contact the rotating lever 18 when it reaches baffle 8. Lever 18 will then push the bottle to both sides, moving it away from the top of the bottle channel and allowing it to contact vibrating plate 6 again until it can smoothly enter the bottle channel. This avoids the situation where some bottles stand upright with their openings facing down, causing other bottles in the channel to move along the top of the channel, resulting in the bottle and subsequent bottles getting stuck and affecting the smooth progress of subsequent filling.
