Feeding device and feeding equipment

Abstract

This invention discloses a feeding device and feeding equipment. The feeding device includes a base, a support platform, a feeding mechanism, and a magnetic suction structure. The support platform is located on the base, and a material trough is recessed on the top of the support platform for receiving magnetic materials separated by the separation mechanism. The feeding mechanism includes a magnetic suction part that magnetically attracts the magnetic materials in the material trough during its downward stroke. The magnetic suction structure is located below the material trough. During the process of the magnetic materials falling into the material trough after being separated by the separation mechanism, the magnetic suction structure ensures that the first magnetic pole end face of each magnetic material falling into the material trough faces downwards, achieving coarse positioning of the magnetic poles of the magnetic materials. By selecting a magnetic suction part that is compatible with the second magnetic pole end face of the magnetic materials, the magnetic materials can self-align when the magnetic suction part approaches them. This solves the problem that existing feeding devices often encounter issues with the magnetic pole direction of irregularly shaped magnetic materials being uncertain and the mounting surface being difficult to control when feeding them.

Description

Technical Field

[0001] This invention relates to the field of magnetic material feeding technology, and more particularly to feeding devices and feeding equipment. Background Technology

[0002] In automation solution design, conventional alignment methods such as precise positioning and vision-guided alignment are widely used. However, when the magnetic material is irregularly shaped, the position of the magnetic poles of the magnetic material is different from that of regular magnetic materials. Therefore, when picking up and installing magnetic materials, there is an instability in material picking, which leads to the problem that the magnetic pole direction cannot be determined when the magnetic material is installed on the product body, and the installation surface is not easy to control. Summary of the Invention

[0010] Optionally, the feeding device further includes a driving device, which has a second driving part that is movably arranged in the vertical direction. The second driving part is fixedly connected to the magnetic structure to drive the magnetic structure to move up and down.

[0011] Optionally, the magnetic attraction structure includes an electromagnet, and the magnitude of the current in the coil of the electromagnet can be controlled to adjust the magnetic strength of the electromagnet.

[0012] Optionally, the magnetic suction part includes a mounting base and a magnetic suction nozzle, the mounting base is fixedly connected to the driving part, and the magnetic suction nozzle is detachably mounted on the mounting base.

[0013] Optionally, the sidewall of the trough is provided with a through groove that extends vertically.

[0014] Optionally, the drive assembly further includes an adjustment mechanism connected to the first drive unit, the adjustment mechanism being used to adjust the movement of the magnetic suction unit so that the magnetic suction unit also has a horizontal movement stroke and a rotational stroke about the axis set in the up-down direction.

[0015] Optionally, the feeding mechanism further includes a position measuring device and a control device. The position measuring device is used to measure the position of the magnetic material picked up by the magnetic suction part. The control device is electrically connected to the position measuring device and the drive assembly, and is used to control the operation of the drive assembly according to the position measuring device.

[0016] Optionally, the position determination device includes an image acquisition system.

[0017] The present invention also provides a feeding device, the feeding device comprising:

[0018] The frame is equipped with a first separation station and a second separation station.

[0019] A material tube separation device is provided corresponding to the first separation station, used to separate multiple material tubes and transport the separated material tubes to the second separation station;

[0020] A magnet separation device, corresponding to the second separation station, includes a separation mechanism for separating multiple magnetic materials in the material tube one by one; and...

[0021] The feeding device includes:

[0022] Base;

[0023] A support platform is provided on the machine base, and a material trough is recessed on the top of the support platform. The material trough is used to receive the magnetic material separated by the separation mechanism.

[0024] The feeding mechanism includes a drive assembly and a magnetic suction part located above the support platform. The drive assembly has a first drive part that is movably disposed in the vertical direction. The first drive part is fixedly connected to the magnetic suction part to drive the magnetic suction part to move vertically, so that the magnetic suction part magnetically attracts magnetic material in the material trough during its downward stroke; and...

[0025] A magnetic suction structure is located below the material trough.

[0026] In the technical solution provided by this invention, during the process of the magnetic material being separated by the separation mechanism and falling into the material tank, since the magnetic attraction structure is located below the material tank, the magnetic pole at the top of the magnetic attraction structure can be set to be opposite to the magnetic pole of the first magnetic end face that the magnetic material needs to face downwards. According to the law of attraction between opposite magnetic poles, the first magnetic end face of the magnetic material falling into the material tank each time can be consistently facing downwards, thereby achieving coarse positioning of the magnetic pole of the magnetic material. Since the magnetic material is irregularly shaped, its second magnetic end face may be tilted, and the positions of the second magnetic end face of different magnetic materials falling into the material tank on their respective horizontal planes are different. Therefore, the distribution of magnetic field lines of the magnetic material is inconsistent. In order to ensure that the magnetic attraction range of the magnetic attraction part can cover the material tank, the magnetic attraction structure can be adjusted accordingly. Different magnetic materials in the material tank ensure that the magnetic poles of the magnetic materials can be attracted by the magnetic suction unit regardless of the direction the second magnetic pole faces, and achieve self-alignment and flipping. The magnetic suction unit can be selected to ensure that it is compatible with the second magnetic poles of the magnetic materials. When the magnetic suction unit approaches the magnetic materials, the magnetic materials can automatically flip around the horizontally extending axis to achieve self-alignment. This allows the second magnetic poles of the magnetic materials to be stably attracted and engaged with the magnetic suction unit, which facilitates the subsequent assembly of the magnetic materials into the product body. It ensures that the magnetic materials are in a stable set position, and facilitates the precise positioning of the mounting surface of the magnetic materials. This solves the problem that existing feeding devices often cannot determine the magnetic pole direction of the magnetic materials and are difficult to control the mounting surface when feeding irregularly shaped magnetic materials.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0038] In automation solution design, conventional alignment methods such as precise positioning and vision-guided alignment are widely used. However, when the magnetic material is irregularly shaped, the position of the magnetic poles of the magnetic material is different from that of regular magnetic materials. Therefore, when picking up and installing magnetic materials, there is an instability in material picking, which leads to the problem that the magnetic pole direction cannot be determined when the magnetic material is installed on the product body, and the installation surface is not easy to control.

[0039] To address the above problems, the present invention provides a feeding device. Figures 1 to 3 This is a specific embodiment of the feeding device provided by the present invention.

[0040] Please see Figures 1 to 3The feeding device includes a base 1, a support platform 2, a feeding mechanism 3, and a magnetic attraction structure 4. The support platform 2 is disposed on the base 1, and a material trough 2a is recessed on the top of the support platform 2. The material trough 2a is used to receive the magnetic material 100 separated by the separation mechanism. The feeding mechanism 3 includes a driving component 31 and a magnetic attraction part 32 located above the support platform 2. The driving component 31 has a first driving part that is movably disposed in the vertical direction. The first driving part is fixedly connected to the magnetic attraction part 32 to drive the magnetic attraction part 32 to move in the vertical direction, so that the magnetic attraction part 32 magnetically attracts the magnetic material 100 in the material trough 2a during its downward stroke. The magnetic attraction structure 4 is located below the material trough 2a.

[0041] In the technical solution provided by this invention, during the process of the magnetic material 100 being separated by the separation mechanism and falling into the material tank 2a, since the magnetic attraction structure 4 is located below the material tank 2a, the magnetic pole at the top of the magnetic attraction structure 4 can be set to be opposite to the magnetic pole of the first magnetic end face that the magnetic material 100 needs to face downwards. According to the law of attraction between opposite magnetic poles, the first magnetic end face of the magnetic material 100 falling into the material tank 2a each time can face downwards in a consistent manner, thereby achieving coarse positioning of the magnetic pole of the magnetic material 100. Since the magnetic material 100 is irregularly shaped, its second magnetic end face may be tilted, and the positions of the second magnetic end face of different magnetic materials 100 falling into the material tank 2a on their respective horizontal planes are different. Therefore, the distribution of magnetic field lines of the magnetic material 100 is inconsistent. In order to ensure that the magnetic attraction range of the magnetic attraction part 32 can cover the material tank 2a... For different magnetic materials, the magnetic material 100 can be magnetically attracted by the magnetic suction part 32 regardless of the direction its second magnetic pole end faces, and can achieve self-alignment and flipping. The magnetic suction part 32 can be selected to ensure that it is compatible with the second magnetic pole end face of the magnetic material 100. When the magnetic suction part 32 approaches the magnetic material 100, the magnetic material 100 can automatically flip around the horizontally extending axis to achieve self-alignment. This allows the second magnetic pole end face of the magnetic material 100 to be stably magnetically attracted and engaged with the magnetic suction part 32. This facilitates the subsequent assembly of the magnetic material 100 into the product body, ensuring that the magnetic material 100 is in a stable set position. It also facilitates the precise positioning of the mounting surface of the magnetic material 100, thus solving the problem that existing feeding devices often cannot determine the magnetic pole direction of the magnetic material 100 and the mounting surface is difficult to control when feeding irregularly shaped magnetic materials 100.

[0042] It should be noted that the selection of the magnetic attraction part 32 can be achieved first by analyzing the magnetic field distribution of the magnetic material 100, and confirming the polarity of the magnetic attraction part 32 through the polarity and magnetic field line distribution of the magnetic material 100. Then, after confirming the polarity of the magnetic attraction part 32, several existing standard magnet types are selected as candidate magnetic attraction parts 32. Next, the optimal standard magnet model (1 to 3 types) is determined by analyzing the magnetic field and magnetic field lines of the magnetic material 100 using 3D software. Finally, the optimal 1 to 3 standard magnets are physically verified to confirm the optimal standard magnet model for the magnetic attraction part 32. Through the above selection of the magnetic attraction part 32, the self-alignment accuracy of the magnetic attraction part 32 at the center of the magnetic material 100 can be controlled within ±0.5mm.

[0043] Specifically, in the first embodiment, the magnetic attraction structure 4 is located below the support platform 2 and is movably arranged vertically. Thus, when initial magnetic pole positioning of the magnetic material 100 is required, the magnetic attraction structure 4 can move upwards. As the magnetic attraction structure 4 gradually moves upwards towards the material trough 2a, the magnetic field generated by the magnetic attraction structure 4 gradually strengthens its magnetic force on the magnetic material 100 near the material trough 2a. This allows each magnetic material 100 to flip and adjust its magnetic poles before falling to the bottom of the material trough 2a, so that the first magnetic end face of the magnetic material 100 faces downwards. When the magnetic attraction part 32 moves downwards to pick up material, to facilitate the adsorption and pickup of the magnetic material 100, the magnetic attraction structure 4 can move downwards away from the material trough 2a. The magnetic field exerted by the magnetic attraction structure 4 on the magnetic material 100 gradually weakens, so that the magnetic material 100 is no longer bound by the magnetic force of the magnetic attraction structure 4, making it easier for the magnetic attraction part 32 to magnetically attract the magnetic material 100.

[0044] Specifically, in this embodiment, the feeding device further includes a driving device 41. The driving device 41 has a second driving part that is movably arranged in the vertical direction. The second driving part is fixedly connected to the magnetic suction structure 4 to drive the magnetic suction structure 4 to move up and down. The present invention does not limit the specific structure of the driving device 41, and it can be a cam shaft drive, a connecting rod drive, a lead screw structure, etc. Preferably, the driving device 41 includes a cylinder or an electric cylinder. When the driving device 41 is set as a cylinder, the cylinder rod is set as the driving part.

[0045] In the second embodiment, the magnetic attraction structure 4 includes an electromagnet, and the current of the electromagnet's coil can be controlled to adjust the strength of the electromagnet's magnetism. It is understood that the electromagnet can be located at the bottom of the material trough 2a or adjacent to the bottom of the material trough 2a. Thus, when initial magnetic pole positioning of the magnetic material 100 is required, the current of the electromagnet's coil can be increased. The magnetic field generated by the electromagnet gradually strengthens the magnetic force on the magnetic material 100 near the material trough 2a, allowing each magnetic material 100 to flip and adjust its magnetic poles before falling to the bottom of the material trough 2a, so that the first magnetic end face of the magnetic material 100 faces downwards. Conversely, when the current of the electromagnet's coil decreases, the magnetic field acting on the magnetic material 100 gradually weakens, so that the magnetic material 100 is no longer magnetically bound by the magnetic attraction structure 4, facilitating the magnetic attraction part 32 to magnetically attract the magnetic material 100.

[0046] Specifically, because the position and tilt angle of the second magnetic end face of the magnetic material 100 change after it falls into the material tank 2a, especially for different magnetic materials 100, the magnetic suction part 32 needs to be adjusted according to different batches of magnetic materials 100. In this embodiment, the magnetic suction part 32 includes a mounting base 321 and a magnetic suction nozzle 322. The mounting base 321 is fixedly connected to the driving part, and the magnetic suction nozzle 322 is detachably mounted on the mounting base 321. Thus, after changing the magnetic material 100, the magnetic lines of force of the magnetic material 100 falling into the material tank 2a can be analyzed again to select the optimal standard magnet as the magnetic suction nozzle 322, and the previously unsuitable magnetic suction nozzle 322 can be disassembled and the suitable magnetic suction nozzle 322 can be installed on the mounting base 321.

[0047] Furthermore, in this embodiment, a through groove 2b is provided through the side wall of the material tank 2a, and the through groove 2b extends vertically. This arrangement facilitates timely observation of the status of the magnetic material 100 in the material tank 2a, and determines whether there is magnetic material 100 in the material tank 2a. It avoids the stacking of multiple magnetic materials 100 or the occurrence of empty material.

[0048] Furthermore, after the magnetic suction part 32 picks up the magnetic material 100, in order to facilitate subsequent precise assembly, in this embodiment, the driving assembly 31 further includes an adjustment mechanism connected to the first driving part. The adjustment mechanism is used to adjust the movement of the magnetic suction part 32, so that the magnetic suction part 32 also has a horizontal movement stroke and a rotation stroke around the axis set to the up and down direction. Since the self-alignment accuracy of the magnetic suction part 32 in the center of the magnetic material 100 is controlled within ±0.5mm, in order to facilitate fine adjustment of the precise position of the magnetic material 100, the adjustment mechanism can adjust the position of the magnetic suction part 32 in the horizontal and vertical directions, and can also adjust its angle, so that the magnetic suction part 32 can drive the magnetic material 100 to be adjusted to the set position.

[0049] Furthermore, in this embodiment, the feeding mechanism 3 further includes a position measuring device and a control device. The position measuring device is used to measure the position of the magnetic material 100 picked up by the magnetic suction part 32. The control device is electrically connected to the position measuring device and the drive assembly 31, and is used to control the operation of the drive assembly 31 according to the position measuring device. In this way, by measuring the position of the magnetic material 100 on the magnetic suction part 32 in real time, the initial position of the magnetic material 100 can be accurately obtained. By comparing and analyzing the data with the set position, the required displacement and rotation angle of the magnetic material 100 in the horizontal and vertical directions can be obtained. Then, the control device controls the drive assembly 31 to adjust so that the magnetic suction part 32 can drive the magnetic material 100 to the set position.

[0050] The drive assembly 31 may further include a first drive device, a second drive device, and a third drive device. The first drive device is connected to the drive part that can move vertically. The first drive device has a first drive part that can move horizontally. The second drive device is fixedly connected to the first drive part. The second drive device has a second drive part that can move vertically. The third drive device is fixedly connected to the second drive part. The third drive device has a rotating shaft that extends vertically. The magnetic suction part 32 is fixedly connected to the rotating shaft.

[0051] Of course, the assembly and connection relationship of the first driving device, the second driving device and the third driving device is not limited to the connection method described above. Other driving forms that can ultimately enable the magnetic suction part 32 to rotate along the horizontal, vertical and vertical axes are all within the protection scope of this invention.

[0052] Specifically, in this embodiment, the position measuring device includes an image acquisition system. Thus, by acquiring images, the device can compare them with images of the magnetic material 100 at a set position, thereby intuitively and quickly obtaining the position offset. The detection method is simple, fast, and easy to operate.

[0053] The present invention also provides a feeding device, which includes a frame, a tube separation device, a magnet separation device, and a feeding device. The frame is provided with a first separation station and a second separation station. The tube separation device is provided corresponding to the first separation station and is used to separate multiple tubes and transport the separated tubes to the second separation station. The magnet separation device is provided corresponding to the second separation station and includes a separation mechanism. The separation mechanism is used to separate multiple magnetic materials 100 in the tubes one by one. Since the feeding device includes the feeding device, the specific structure of the feeding device is as described in the above embodiments. Since the feeding device of this feeding device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0054] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
