Description

Technical Field

[0001] This invention relates to the field of feeding device technology, specifically to an automatic feeding device and process for processing aluminum heat sink strips with positioning and monitoring functions. Background Technology

[0002] In the field of aluminum heat sink processing, the feeding device is a crucial link in the production process. Existing automatic feeding devices for aluminum heat sink processing have many problems in practical applications.

[0003] On the one hand, insufficient feeding precision makes it difficult to accurately position the aluminum pillars, causing them to easily shift during the feeding process. This not only affects the quality of extrusion molding but may also damage the extruder and reduce its service life. On the other hand, limited automation and a lack of effective real-time monitoring and adjustment mechanisms prevent timely dynamic adjustments based on changes in the aluminum pillar's position, resulting in low feeding efficiency and making it difficult to meet the needs of large-scale production. Therefore, this invention proposes an automatic feeding device and process for aluminum heat sink processing with positioning monitoring function to solve the aforementioned problems in the prior art. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding device and process for processing aluminum heat sink strips with positioning and monitoring functions, so as to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic feeding device for processing aluminum heat sink strips with positioning monitoring function. The automatic feeding device includes an extruder, a feeding box, a feeding device, a positioning device, a positioning disc, and a drive device. The feeding box is placed below the extruder, the feeding device is placed inside the feeding box, the feeding device is connected to the feeding box, the positioning device is connected to the feeding device, the positioning disc is connected to the drive device, and the drive device is connected to the extruder.

[0007] After the equipment is installed in the production line, the aluminum column is fed to the feeding device by the equipment on the production line. Then, the feeding device and the positioning device work together to adjust the position of the aluminum column on the feeding device and send the aluminum column to the designated position. At the same time, the drive device sends the positioning disc to the designated position. Then, the positioning device and the positioning disc work together to monitor the position of the feeding device in real time and adjust the position of the feeding device to align with the aluminum column inlet of the extruder. After alignment, the drive device resets the positioning disc, and then the aluminum column is extruded into shape by the extruder.

[0008] Furthermore, the feeding device includes a feeding cylinder and a feeding gripper. The feeding cylinder and the feeding box are slidably connected. The output end of the feeding cylinder and the feeding gripper are fastened together. The feeding cylinder is equipped with a driving device, which is used to drive the feeding cylinder to move within the feeding box. The feeding gripper is connected to a positioning device.

[0009] After the aluminum column is fed onto the feeding gripper, the position of the aluminum column is adjusted by the positioning device and the feeding gripper. Then, the feeding cylinder is sent to the designated position by the drive device. Then, the positioning device and the positioning disc output signals to indicate the position of the feeding cylinder. Then, the feeding gripper is moved by the displacement output of the feeding cylinder until it moves to the designated position and stops moving. Then, the aluminum column is extruded by the extruder.

[0010] Furthermore, the feeding gripper includes a gripper plate, a first rotating roller, a clamping plate, and a second rotating roller. The gripper plate is fastened to the output end of the feeding cylinder. There are four clamping plates, which are symmetrically distributed about the gripper plate. A first rotating roller is provided between the gripper plate and the clamping plates. The first rotating roller is rotatably connected to the gripper plate and is fastened to the clamping plates. A second rotating roller is provided between the clamping plates. The clamping plates adjacent to the gripper plate are rotatably connected to the second rotating roller, and the clamping plates away from the gripper plate are fastened to the second rotating roller. The clamping plates are connected to the positioning device, the first rotating roller is connected to the positioning device, and the second rotating roller is connected to the positioning device.

[0011] The gripper plate serves as the main mounting base for installing other components and as the main load-bearing base for supporting the aluminum column. When the aluminum column is placed on the gripper plate, the first rotating roller drives the connected clamping plate to rotate, and the second rotating roller drives the connected clamping plate to rotate. The rotation of the clamping plate fixes the aluminum column on the gripper plate. At the same time, the positioning device limits the rotation angle of the clamping plate, which facilitates the subsequent positioning of the positioning device.

[0012] Furthermore, the positioning device includes a positioning detection device and laser emitters. There are two positioning detection devices, which are respectively connected to the first rotating roller and the second rotating roller. The positioning detection device includes a positioning mounting shell, a positioning baffle, a positioning magnet, and an induction coil. There are four laser emitters, which are located in the middle of the clamping plate. The positioning mounting shell on the first rotating roller is rotatably connected to the first rotating roller, and the positioning baffle on the first rotating roller is fastened to the first rotating roller. The induction coil is placed inside the positioning mounting shell and is fastened to the positioning mounting shell. The positioning mounting shell on the second rotating roller is rotatably connected to the second rotating roller, and the positioning baffle on the second rotating roller is rotatably connected to the second rotating roller. The positioning magnet and the positioning baffle are fastened to each other.

[0013] The positioning detection device, as the main position detection device, is used to adjust the position of the aluminum column. The positioning mounting shell, as the main mounting base, is used for the installation of other components and also plays a certain protective role. The first rotating roller rotates at a certain speed, which drives the positioning baffle to rotate. The rotation of the positioning baffle drives the positioning magnet to rotate. The rotation of the positioning magnet causes a change in the magnetic flux in the induction coil. The electrical signal generated by the change in the magnetic flux in the induction coil determines the rotation angle of the first rotating roller. At the same time, the electrical signal controls the rotation of the second rotating roller, so that the laser emitters on the same side clamp can be vertically distributed, and the center position of the four laser emitters coincides with the center of the aluminum column, thus determining the center of the aluminum column, which facilitates the subsequent delivery of the aluminum column into the extrusion machine.

[0014] Furthermore, the positioning disc includes a support frame, a disc body, a photoresistor, an electromagnet, and a permanent magnet. The support frame is connected to the drive device. The disc body has several first mounting cavities, which are symmetrically distributed about the center of the disc body. The disc body also has four second mounting cavities, each containing an electromagnet. The extruder has four third mounting cavities, each containing a permanent magnet, which is fastened to the third mounting cavities. A photoresistor is located in each of the first mounting cavities, and the first mounting cavities are fastened to the photoresistors.

[0015] The support frame serves as the primary mounting base for positioning other components. When an aluminum column needs to be fed into the extruder, the drive device moves the disc to the designated position, then energizes the electromagnet, making it magnetic. The permanent magnet then attracts the electromagnet, magnetically connecting the disc to the extruder. Corresponding slots are provided in the second and third mounting cavities to fix the connection between the disc and the extruder, facilitating subsequent positioning of the aluminum column. A processor is also located within the disc. A laser emitter illuminates a photoresistor in the first mounting cavity, causing a change in the current flowing through it. Based on the positions of the four laser emitters on the photoresistor, different currents are generated and transmitted to the processor. The processor controls the output of the feeding cylinder and drive device to adjust the position of the aluminum column until it reaches the designated position. The extruder then extrudes the aluminum column, preventing positional shifts during feeding that could damage the extruder and improving its efficiency.

[0016] Furthermore, the drive device includes a support column, a movable sleeve, a connecting frame, and a drive cylinder. The support column is fastened to the extruder, the support column is slidably connected to the movable sleeve, the movable sleeve is connected to the connecting frame, the connecting frame is fastened to the drive cylinder, the output end of the drive cylinder is fastened to the support frame, and a movable motor is installed inside the movable sleeve.

[0017] The support column serves as the main mounting base for positioning other components. The connecting frame is used to connect the drive cylinder. When the disc needs to be moved to a designated position, the moving sleeve is moved by the moving motor, and then the drive cylinder outputs to move the support frame until the disc moves to the designated position.

[0018] Furthermore, the movable sleeve is provided with a mounting groove, the connecting bracket is placed in the mounting groove, and springs are provided at both ends of the connecting bracket. The springs and the connecting bracket are fastened together, and the end of the spring away from the connecting bracket is fastened together with the mounting groove.

[0019] Once the disc moves to the designated position, the electromagnet is energized, causing the permanent magnet to attract the electromagnet to the designated position. The electromagnet drives the support frame to move, which in turn drives the connecting frame to move. The spring installed in the mounting slot allows the connecting frame to move within the moving sleeve, providing tolerance for the connection between the disc and the extruder and improving the positioning accuracy of the aluminum column.

[0020] Furthermore, the processing technology of the automatic feeding device includes the following steps:

[0021] S1. The aluminum column is fed to the feeding equipment by the equipment, and then the feeding equipment feeds the column.

[0022] S2. During the feeding process, the aluminum column is fixed by the positioning device and the feeding equipment, and the position of the aluminum column is limited by the positioning device. Then, the positioning disc is sent to the working area by the driving device.

[0023] S3. Adjust the position of the feeding equipment using the positioning device and positioning disc to prevent the feeding equipment from deviating from its position, and then extrude the aluminum column into shape using an extruder.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention achieves precise positioning of the aluminum column through the synergistic effect of the positioning device and the positioning disk. The positioning detection device in the positioning device uses an induction coil and a positioning magnet to accurately detect the rotation angle of the first rotating roller and the second rotating roller, thereby determining the position of the aluminum column. The laser emitter works in conjunction with the photoresistor on the positioning disk to adjust the position of the aluminum column by controlling the feeding equipment through the processor according to the current change generated at the laser irradiation position, ensuring that the aluminum column is accurately aligned with the extruder inlet, effectively avoiding aluminum column deviation, significantly improving the extrusion molding quality of the aluminum heat sink, and reducing the scrap rate.

[0026] 2. The structure of each part, such as the feeding equipment, positioning device, positioning disc, and driving device, is scientifically and rationally designed. The structure of the feeding gripper can stably fix the aluminum column. The spring set between the moving sleeve and the connecting frame in the driving device provides fault tolerance space for the connection between the positioning disc and the extruder, which enhances the overall stability of the device operation, reduces the probability of failure caused by unstable equipment operation, and lowers maintenance costs.

[0027] 3. The entire feeding process is highly automated. From the aluminum column being fed to the feeding equipment, to its position being fixed and adjusted by the positioning device, to the drive device sending the positioning disc to the working area and completing the aluminum column position calibration, and finally to the extrusion press for extrusion molding, minimal manual intervention is required. The close cooperation between the components enables the feeding operation to be completed quickly and accurately, greatly improving production efficiency and meeting the needs of large-scale production.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example: Figures 1-7 As shown, the present invention provides an automatic feeding device and process technology solution for processing aluminum heat sink strips with positioning and monitoring functions. The automatic feeding device includes an extruder 1, a feeding box 2, a feeding device 3, a positioning device 4, a positioning disc 5, and a driving device 6. The feeding box 2 is placed below the extruder 1, the feeding device 3 is placed inside the feeding box 2, the feeding device 3 is connected to the feeding box 2, the positioning device 4 is connected to the feeding device 3, the positioning disc 5 is connected to the driving device 6, and the driving device 6 is connected to the extruder 1.

[0038] After the equipment is installed in the production line, the aluminum column is fed to the feeding device 3 by the equipment on the production line. Then, the feeding device 3 and the positioning device 4 work together to adjust the position of the aluminum column on the feeding device 3 and send the aluminum column to the designated position. At the same time, the drive device 6 sends the positioning disc 5 to the designated position. Then, the positioning device 4 and the positioning disc 5 work together to monitor the position of the feeding device 3 in real time and then adjust the position of the feeding device 3 to align with the aluminum column inlet of the extruder 1. After alignment, the drive device 6 resets the positioning disc 5, and then the aluminum column is extruded into shape by the extruder 1.

[0039] like Figures 1-2 As shown, the feeding device 3 includes a feeding cylinder 31 and a feeding gripper 32. The feeding cylinder 31 and the feeding box 2 are slidably connected. The output end of the feeding cylinder 31 and the feeding gripper 32 are fastened together. The feeding cylinder 31 is equipped with a driving device, which is used to drive the feeding cylinder 31 to move within the feeding box 2. The feeding gripper 32 is connected to the positioning device 4.

[0040] After the aluminum column is fed onto the feeding gripper 32, the position of the aluminum column is adjusted by the positioning device 4 and the feeding gripper 32. Then, the feeding cylinder 31 is sent to the designated position by the drive device. Then, the positioning device 4 and the positioning disc 5 output signals to indicate the position of the feeding cylinder 31. Then, the feeding cylinder 31 outputs displacement to drive the feeding gripper 32 to move until the feeding gripper 32 moves to the designated position and stops moving. Then, the aluminum column is extruded by the extruder 1.

[0041] like Figures 1-3As shown, the feeding gripper 32 includes a gripper plate 321, a first rotating roller 322, a clamping plate 323, and a second rotating roller 324. The gripper plate 321 is fastened to the output end of the feeding cylinder 31. There are four clamping plates 323, which are symmetrically distributed about the gripper plate 321. The first rotating roller 322 is provided between the gripper plate 321 and the clamping plate 323. The first rotating roller 322 is rotatably connected to the gripper plate 321 and is fastened to the clamping plate 323. The second rotating roller 324 is provided between the clamping plates 323. The clamping plates 323 adjacent to the gripper plate 321 and the second rotating roller 324 are rotatably connected. The clamping plates 323 away from the gripper plate 321 and the second rotating roller 324 are fastened to the second rotating roller 324. The clamping plate 323 is connected to the positioning device 4. The first rotating roller 322 is connected to the positioning device 4, and the second rotating roller 324 is connected to the positioning device 4.

[0042] The gripper plate 321 serves as the main mounting base for installing other components and as the main load-bearing base for supporting the aluminum column. When the aluminum column is delivered onto the gripper plate 321, the first rotating roller 322 drives the connected clamping plate 323 to rotate, and the second rotating roller 324 drives the connected clamping plate 323 to rotate. Thus, the rotation of the clamping plate 323 fixes the aluminum column on the gripper plate 321. At the same time, the positioning device 4 limits the rotation angle of the clamping plate 323, which facilitates the subsequent positioning of the positioning device 4.

[0043] like Figures 2-3 As shown, the positioning device 4 includes a positioning detection device 41 and a laser emitter 42. There are two positioning detection devices 41, which are respectively connected to the first rotating roller 322 and the second rotating roller 324. The positioning detection device 41 includes a positioning mounting shell 411, a positioning baffle 412, a positioning magnet 413, and an induction coil 414. There are four laser emitters 42, which are located in the middle of the clamping plate 323. The positioning mounting shell 411 on the first rotating roller 322 and the first rotating roller 324 are connected to the first rotating roller 322. The first rotating roller 322 is rotatably connected to the positioning baffle 412 on the first rotating roller 322. The induction coil 414 is placed inside the positioning mounting shell 411 and is tightly connected to the positioning mounting shell 411. The positioning mounting shell 411 on the second rotating roller 324 is rotatably connected to the second rotating roller 324. The positioning baffle 412 on the second rotating roller 324 is rotatably connected to the second rotating roller 324. The positioning magnet 413 is tightly connected to the positioning baffle 412.

[0044] The positioning detection device 41 serves as the main position detection device, used to adjust the position of the aluminum column. The positioning mounting shell 411 serves as the main mounting base, used for the installation of other components, and also provides a certain degree of protection. The first rotating roller 322 rotates at a certain speed, driving the positioning baffle 412 to rotate. The rotation of the positioning baffle 412 drives the positioning magnet 413 to rotate. The rotation of the positioning magnet 413 causes a change in the magnetic flux in the induction coil 414. The change in the magnetic flux in the induction coil 414 generates an electrical signal, which determines the rotation angle of the first rotating roller 322. At the same time, the electrical signal controls the second rotating roller 324 to rotate, ultimately allowing the laser emitters 42 on the same side clamp 323 to be vertically distributed, so that the center position of the four laser emitters 42 coincides with the center of the aluminum column, thus determining the center of the aluminum column and facilitating the subsequent delivery of the aluminum column into the extruder 1.

[0045] like Figures 4-6 As shown, the positioning disc 5 includes a support frame 51, a disc body 52, a photoresistor 53, an electromagnet 54, and a permanent magnet 55. The support frame 51 is connected to the driving device 6. The disc body 52 is provided with a plurality of first mounting cavities 521, which are symmetrically distributed about the center of the disc body 52. ​​The disc body 52 is also provided with four second mounting cavities 522, each containing an electromagnet 54. The extruder 1 is provided with four third mounting cavities 11, each containing a permanent magnet 55. The permanent magnet 55 and the third mounting cavity 11 are fastened together. The first mounting cavity 521 contains a photoresistor 53, which is fastened together.

[0046] The support frame 51 serves as the main mounting base for positioning other components. When the aluminum column needs to be fed into the extruder 1, the drive device 6 moves the disc 52 to the designated position, then energizes the electromagnet 54, making it magnetic. The permanent magnet 55 then attracts the electromagnet 54, magnetically connecting the disc 52 and the extruder 1. Corresponding slots are provided on the second mounting cavity 522 and the third mounting cavity 11 to fix the connection position between the disc 52 and the extruder 1, facilitating subsequent positioning of the aluminum column. The disc 52 also contains a processor. After the laser emitter 42 emits a laser beam that irradiates the photoresistor 53 in the first mounting cavity 521, the current flowing through the photoresistor 53 changes. Based on the positions of the four laser emitters 42 irradiating the photoresistor 53, the current generated at different positions is transmitted to the processor. The processor controls the output of the feeding cylinder 31 and the drive device to adjust the position of the aluminum column until the aluminum column is adjusted to the designated position. Then, the extruder 1 extrudes and feeds the aluminum column to prevent the position of the aluminum column from shifting during the feeding process, thereby preventing damage to the extruder 1 and improving the working efficiency of the extruder 1.

[0047] like Figures 4-6 As shown, the drive device 6 includes a support column 61, a movable sleeve 62, a connecting frame 63, and a drive cylinder 64. The support column 61 is fastened to the extruder 1, the support column 61 is slidably connected to the movable sleeve 62, the movable sleeve 62 is connected to the connecting frame 63, the connecting frame 63 is fastened to the drive cylinder 64, the output end of the drive cylinder 64 is fastened to the support frame 51, and a movable motor is provided inside the movable sleeve 62.

[0048] The support column 61 serves as the main mounting base for positioning other components. The connecting frame 63 is used to connect the drive cylinder 64. When the disc 52 needs to be moved to the designated position, the moving sleeve 62 is moved by the moving motor, and then the drive cylinder 64 outputs to move the support frame 51 until the disc 52 moves to the designated position.

[0049] like Figure 6 As shown, the movable sleeve 62 is provided with a mounting groove 621, the connecting frame 63 is placed in the mounting groove 621, and the connecting frame 63 is provided with springs 622 at both ends. The springs 622 and the connecting frame 63 are fastened together, and the end of the spring 622 away from the connecting frame 63 is fastened together with the mounting groove 621.

[0050] When the disc 52 moves to the designated position, the electromagnet 54 is energized, causing the permanent magnet 55 to attract the electromagnet 54 to the designated position. The electromagnet 54 drives the support frame 51 to move, and the movement of the support frame 51 drives the movement of the connecting frame 63. The spring 622 set in the mounting groove 621 allows the connecting frame 63 to move within the moving sleeve 62, providing fault tolerance for the connection between the disc 52 and the extruder 1 and improving the positioning accuracy of the aluminum column.

[0051] like Figures 1-7 As shown, the processing technology of the automatic feeding device includes the following steps:

[0052] S1. The aluminum column is fed to the feeding device 3 by the equipment, and then the feeding device 3 feeds the material.

[0053] S2. During the feeding process, the aluminum column is fixed by the positioning device 4 and the feeding equipment 3, and the position of the aluminum column is limited by the positioning device 4. Then, the positioning disc 5 is sent to the working area by the driving device 6.

[0054] S3. The position of the feeding device 3 is adjusted by the positioning device 4 and the positioning disc 5 to prevent the feeding device 3 from deviating from its position. Then, the aluminum column is extruded and formed by the extruder 1.

[0055] The working principle of this invention is as follows: After the equipment is installed in the production line, when the aluminum column is fed onto the gripper plate 321, the first rotating roller 322 rotates at a certain speed, driving the positioning baffle 412 to rotate. The rotation of the positioning baffle 412 drives the positioning magnet 413 to rotate. The rotation of the positioning magnet 413 causes a change in the magnetic flux within the induction coil 414. The electrical signal generated by this change in magnetic flux within the induction coil 414 determines the rotation angle of the first rotating roller 322. Simultaneously, the electrical signal controls the rotation of the second rotating roller 324, ultimately allowing the laser emitters 42 on the same side of the clamping plate 323 to be vertically distributed, so that the center positions of the four laser emitters 42 coincide with the center of the aluminum column. When it is necessary to feed the aluminum column... When the disc 52 is placed into the extruder 1, the drive device 6 sends it to the designated position. Then, the electromagnet 54 is energized, making it magnetic. The permanent magnet 55 then attracts the electromagnet 54, magnetically connecting the disc 52 and the extruder 1. The laser emitter 42 then emits a laser beam that irradiates the photoresistor 53 in the first mounting cavity 521, causing a change in the current flowing through the photoresistor 53. Based on the positions of the four laser emitters 42 irradiating the photoresistor 42, the current generated at different positions is transmitted to the processor. The processor controls the output of the feeding cylinder 31 and the drive device to adjust the position of the aluminum column until it is adjusted to the designated position. Then, the extruder 1 extrudes the aluminum column to prevent the position of the aluminum column from shifting during the feeding process.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
