[0047] The present application provides a material feeding mechanism, Figures 1 to 3 The present application provides a material feeding mechanism.

[0048] Please refer to Figures 1 to 2The material loading mechanism 100 comprises a base 1, a hopper assembly 2, a material taking assembly 3, a discharging mechanism and a separating mechanism, the base 1 is provided with a separating station a, the hopper assembly 2 is formed with a material channel 21 for arranging a plurality of material pipes 200, the material channel 21 extends in the up-down direction and is arranged separately from the base 1; the material taking assembly 3 comprises a carrying part 31, the carrying part 31 is movably arranged between the base 1 and the material channel 21, the carrying part 31 has a material taking position corresponding to the lower end of the material channel 21 and an upper loading position separated from the material channel 21 in the movable stroke; the discharging assembly 4 comprises a driving part 41, the driving part 41 is movably arranged and used for driving each magnetic material in the material pipe 200 in the upper loading position to move from the material pipe 200 to the separating station a in sequence; the separating assembly 5 comprises a separating part 51 movably arranged in the up-down direction, the separating part 51 is used for abutting against the magnetic material in the separating station a in the up-down movement process, so that the magnetic material in the separating station a is separated from other magnetic materials in the material pipe 200.

[0049] In the technical scheme of the present application, the material pipes 200 are used for containing magnetic materials, a plurality of material pipes 200 are stacked in the material channel 21 extending in the up-down direction, the carrying part 31 takes out a single material pipe 200 containing magnetic materials from the material channel 21 and moves to the upper loading position away from the material channel 21, the driving part 41 moves a magnetic material close to the pipe opening in the material pipe 200 from the material pipe 200 to the separating station a, when the magnetic material is in the separating station a, the separating part 51 abuts against the magnetic material in the separating station a, further movement of the separating part 51 separates the magnetic material in the separating station a from other magnetic materials in the material pipe 200, the driving part 41 continues to move the magnetic material close to the pipe opening in the material pipe 200 to the separating station a, the separating part 51 separates the magnetic material in the separating station a from other magnetic materials in the material pipe 200 again, and separates a single magnetic material, thereby sequentially completing the loading of a single magnetic material, and by selecting material pipes 200 of different sizes, regular-shaped magnetic materials and irregular-shaped magnetic materials can be compatible, and universal design is realized.

[0050] The application does not limit the specific form of the bearing part 31, which can be provided as a clamp jaw or a suction head or the like. In an embodiment, the upper end of the bearing part 31 is concavely provided with a separation groove. Thus, when the bearing part 31 moves to the material taking position, the slot of the separation groove corresponds to the lower end of the material channel 21, facilitating the receiving. It can be understood that the shape of the separation groove can be matched with the shape of the material pipe 200, and can be designed in a profiled manner to avoid the shaking of the material pipe 200 in the separation groove, so that the state of the magnetic material in the material pipe 200 is stable.

[0051] The application does not limit the driving mode of the bearing part 31, which can be driven by a convex shaft, a connecting rod, a lead screw structure or the like. In the embodiment, the bearing part 31 is driven by a pneumatic cylinder to translate and realize the conversion between the two positions.

[0052] Further, please refer to Figure 2 The bin assembly 2 includes two seat bodies arranged in a transverse direction, and each of the two seat bodies is concavely provided with a material groove on the side close to each other. Each of the material grooves extends in the up-down direction and penetrates the top of the corresponding seat body upwardly. The material channel 21 is formed between the two material grooves. Since the two seat bodies are arranged in a transverse direction, after the two ends of the material pipe 200 are respectively mounted to the corresponding seat bodies, the remaining amount of the material pipe 200 between the two seat bodies can be observed in real time, facilitating the timely replenishment of the material pipe 200. Specifically, a stop structure can be provided at the bottom of the seat body, so that a single material pipe 200 can naturally fall under the action of gravity, and the remaining material pipes 200 will not fall successively, so that the bearing part 31 only carries one material pipe 200 at a time.

[0053] It can be understood that the distance between the two seat bodies can be close to or away from each other, so that the distance between the two seat bodies can be adjusted according to the length of the material pipe 200, so that the width of the material channel 21 can be matched with the length of the material pipe 200.

[0054] The way to realize the movement of the plurality of magnetic materials in the material pipe 200 to the separation station a in turn can be a push rod at the end of the material pipe 200 away from the separation station a, which can push the plurality of magnetic materials in the material pipe 200 towards the separation station a. Of course, an adsorption rod can also be arranged at the side of the material pipe 200 close to the separation station a, which can drag the plurality of magnetic materials in the material pipe 200 towards the separation station a. Considering that the magnetic materials in the material pipe 200 are different in size or shape, when the push rod is arranged at the end of the material pipe 200 away from the separation station a to push, the adjacent two magnetic materials are prone to misalignment and jamming, and it is difficult to achieve the purpose of moving the magnetic materials close to the separation station a to the separation station a. Therefore, the driving part 41 is preferably arranged as an adsorption rod with adsorption function, which is arranged in transverse direction with the bearing part 31, and has a material taking position and a positioning position in its active stroke. In the material taking position, the adsorption rod is used to approach the pipe opening of the material pipe 200 to adsorb the magnetic materials adjacent to the pipe opening in the material pipe 200. In the positioning position, the adsorption rod is used to move away from the pipe opening of the material pipe 200 to pull the adsorbed magnetic materials to the separation station a. In this way, by adsorbing and pulling outward, misalignment between the adjacent two magnetic materials in the material pipe 200 is avoided.

[0055] The following describes the corresponding devices with the driving part 41 arranged as an adsorption rod as an example.

[0056] It should be noted that when the length of the material pipe 200 is constant, when the magnetic materials in the material pipe 200 are different in shape, and different magnetic materials are installed to the material pipe 200, the total length of the plurality of magnetic materials in the pipe is difficult to be just consistent with the length of the material pipe 200. When the magnetic materials in the material pipe 200 need to be adsorbed, the adsorption rod needs to be inserted into the material pipe 200 for adsorption, and therefore the active stroke distance of the adsorption rod needs to be adjusted.

[0057] In order to realize the separation of a single magnetic material, please refer to Figure 3In one embodiment, the discharging assembly 4 further comprises a carrier table 42 and a magnetic attraction part 43. The carrier table 42 is arranged transversely apart from the carrier part 31, and the gap between the carrier table 42 and the carrier part 31 forms the separation station a. The magnetic attraction part 43 is arranged on the carrier table 42, and is arranged corresponding to the pipe opening of the material pipe 200 to magnetically attract the magnetic material in the material pipe 200. The driving part 41 is arranged on the side of the magnetic attraction part 43 away from the carrier part 31, and is used to magnetically attract and fix the magnetic material through the magnetic attraction part 43 in the active stroke. In this way, the active stroke distance of the suction rod does not need to be adjusted, and only the length of the magnetic attraction part 43 needs to be adjusted. When the magnetic material close to the pipe opening in the pipe is far away from the pipe opening, a longer magnetic attraction part 43 can be selected, and the suction rod can still attract and take the material through the magnetic attraction part 43 while the active distance of the suction rod remains unchanged. Conversely, when the magnetic material close to the pipe opening in the pipe is close to the pipe opening, a shorter magnetic attraction part 43 can be selected.

[0058] Further, in the present embodiment, the magnetic attraction part 43 comprises a plurality of magnets arranged in sequence in the transverse direction, and each adjacent two magnets are magnetically connected. In this way, the magnetic attraction part 43 is arranged in a segmented manner, and the number of magnets can be flexibly set according to the distance of the magnetic material close to the pipe opening from the pipe opening, so as to adjust the length of the magnetic attraction part 43. Of course, the magnets themselves have a certain magnetism, and when the magnetic material close to the pipe opening of the material pipe 200 is attracted and fixed, the magnetic force for attracting the magnetic material becomes larger, and the attracted and taken magnetic material is less likely to be separated when pulled to the separation station a. It should be further noted that the magnets can be arranged as standard accessories, or the same batch of magnetic material as the magnetic material in the material pipe 200 can be used as the magnets.

[0059] Further, in order to avoid that the magnetic attraction part 43 moves with the attracted magnetic material when the magnetic attraction between the magnetic attraction part 43 and the suction rod is insufficient during the separation of the magnetic material, in the present embodiment, the separation mechanism further comprises a first pressing head, which is arranged to move in the up-down direction, and is used to press the magnetic attraction part 43 against the carrier table 42 in the downward movement. In this way, the magnetic material adjacent to the magnetic material in the separation station a is restricted and positioned by the pipe opening of the material pipe 200, and the magnetic attraction part 43 is restricted by the carrier table 42 and the first pressing head, so that the separation part 51 can more easily separate the magnetic material.

[0060] In the embodiment, the separating mechanism further comprises a second pressing head movably arranged in the up-down direction, used for pressing the tube 200 against the bearing part 31 in the downward movement stroke. In this way, the tube 200 is limited between the bearing part 31 and the second pressing head, avoiding the possibility of the tube 200 being lifted up when the separating part 51 separates the magnetic materials.

[0061] It can be understood that the separated single magnetic material can be received by the receiving bin arranged at the separating station a, and can be guided out through a conduit or other auxiliary mechanism, so as to be processed subsequently.

[0062] Based on the above-described material feeding mechanism 100, the application further provides a material feeding method, which is compatible with regular-shaped magnetic materials and irregular-shaped magnetic materials, and can provide a stable and versatile feeding process. Specifically, please refer to Figure 4 , the material feeding method comprises the following steps:

[0063] S10: sequentially stacking a plurality of tubes 200 in the material channel 21,

[0064] It should be noted that a plurality of magnetic materials are placed in each tube 200 by magnetic attraction, i.e. in the initial state, a plurality of magnetic materials are attracted to each other in a long strip structure and connected to each other in the tube 200. It should be understood that the tube 200 should be made of insulating material to ensure the smooth removal of the magnetic materials.

[0065] S20: receiving the tube 200 located at the bottom of the material channel 21 by the bearing part 31, and moving the tube 200 to the feeding position.

[0066] It should be noted that this step is to separate the stacked plurality of tubes 200, and the bearing part 31 receives a single tube 200 at a time. The tube 200 can naturally fall under the action of gravity, so as to be received by the bearing part 31.

[0067] S30: controlling the driving part 41 to cooperate with the separating part 51 to remove the plurality of magnetic materials in the tube 200 at the feeding position.

[0068] In the technical solution of the application, the tubes 200 loaded with magnetic materials are stacked in the material channel 21 by manual or machine, then the first separation is performed, i.e. the plurality of tubes 200 are separated to remove a single tube 200, then the second separation is performed, i.e. the plurality of magnetic materials connected by magnetic attraction in the single tube 200 are separated from each other to obtain a single magnetic material, so as to be processed subsequently. The equipment and station layout are compatible with the feeding of regular-shaped and irregular-shaped magnetic materials, and have good stability.

[0069] It can be understood that in the embodiment of the present application, in step S10, at least part of the plurality of magnetic materials placed in each said material pipe 200 is a special-shaped magnetic material. That is, the present application does not limit the shape of the material in the material pipe 200, which can be a regular-shaped magnetic material, such as a long strip magnet, or a special-shaped magnetic material, or a mixture of regular-shaped and special-shaped magnetic materials, as long as the polarity of the plurality of magnetic materials can be attracted to each other, and the material pipe 200 with a suitable shape and size can be placed. Since the shape of the material pipe 200 itself is regular, it is very convenient to perform feeding and material channel 21 stacking.

[0070] Further, the step S30 comprises:

[0071] S31: controlling the driving part 41 to work to drive the plurality of magnetic materials connected by adsorption to extend from the material pipe 200 at the feeding position, and move one of the magnetic materials to a separation station a;

[0072] It can be understood that in the step of separating the plurality of magnetic materials, the strip structure connected by adsorption needs to be taken out of the material pipe 200, which can be pushed out in the form of a push rod or pulled out in the form of a suction rod. At this time, the plurality of magnetic materials will move synchronously, but since the connection between them has a certain length, the magnetic material at the edge will be exposed to the material pipe 200 first, so it can reach the separation station a first, realizing the movement of each magnetic material to the separation station a in turn.

[0073] S32: controlling the separation part 51 to move downward to make the magnetic material at the separation station a fall.

[0074] It can be understood that initially, the separation part 51 is above the separation station a, and when one of the magnetic materials is at the separation station a, the separation part 51 is driven to move downward, thereby separating the magnetic material by the downward force. At this time, the remaining magnetic materials are limited by the material pipe 200, so they will not fall.

[0075] Further, in step S31,

[0076] controlling the driving part 41 to move to magnetically attract and fix the magnetic material at the end of the material pipe 200 by the magnetic attraction part 43 in its movement stroke, so as to pull one of the magnetic materials to be suspended between the material carrying table 42 and the carrying part 31.

[0077] It can be understood that the driving part 41 is on the side away from the material pipe 200 of the magnetic attraction part 43, which can drive the magnetic attraction part 43 to move synchronously. In the process of taking materials, the magnetic attraction part 43 first moves with the driving part 41 for an end distance, so as to reach the edge of the material pipe 200 of the bearing part 31 or even extend into the material pipe 200, so as to adsorb and fix the magnetic materials at the edge in the material pipe 200 in the magnetic force range. At this time, the driving part 41 is controlled to move reversely, and under the magnetic attraction, a plurality of magnetic materials will move together until the magnetic attraction part 43 returns to the material loading table 42. At this time, the magnetic materials at the edge connected thereto are arranged at the gap between the material loading table 42 and the bearing part 31 and are arranged in a suspended manner, so that when the magnetic materials are subjected to the force of the separating part 51, the magnetic materials can be separated by means of height difference.

[0078] Further, in step S32,

[0079] The separating part 51 is controlled to move downward, and the magnetic attraction part 43 and the corresponding material pipe 200 are pressed on the material loading table 42 and the bearing part 31 by the first pressing head and the second pressing head respectively.

[0080] It can be understood that the first pressing head and the second pressing head respectively play the roles of fixing the magnetic attraction part 43 and fixing the material pipe 200. The first pressing head and the second pressing head can be in contact with the corresponding magnetic attraction part 43 and material pipe 200 at the same time when the separating part 51 is in contact with the corresponding magnetic materials, or can be in contact with the corresponding magnetic attraction part 43 and material pipe 200 before the separating part 51 is in contact with the corresponding magnetic materials. Different contact times of the three can be realized by setting different initial heights of the first pressing head, the second pressing head and the separating part 51. The main purpose is to avoid that the connecting force between the magnetic attraction part 43 and the driving part 41 is insufficient, or the activity gap of the material pipe 200 on the bearing part 31 is too large, so that when the separating part 51 separates, the magnetic attraction part 43 moves with the magnetic materials attracted by the magnetic attraction part 43 and falls synchronously with the magnetic materials, or the material pipe 200 tilts and pours out the remaining magnetic materials in the material pipe 200 due to the warping of the material pipe 200.

[0081] It should be understood that after step S30,

[0082] S40: Remove the idle material pipe 200 inside the bearing part 31.

[0083] The control of the material pipe 200 can be collected by artificial or other mechanical equipment. The idle material pipe 200 will be placed in the material channel 21 after being filled with materials.

[0084] Furthermore, after step S40,

[0085] S50: control the carrier 31 to return to the taking position to continue to take the tube 200 currently located at the bottom of the tube 200.

[0086] It should be noted that when the taking position, the carrier 31 only picks up the tube 200 currently located at the bottom of the tube 200, and then moves it to the feeding position. After completing the separation and removal of all magnetic materials in the tube 200, the empty tube 200 is removed from the carrier 31. At this time, the empty carrier 31 returns to the initial taking position, thereby completing a cycle of the feeding process.

[0087] It should be understood that when a single magnetic material is separated from the tube 200, a feeding process is completed, and the single magnetic material taken out can be subjected to subsequent processing steps without waiting for all magnetic materials to be taken out.

[0088] It should be noted that the remaining equipment can be provided with two sets, three sets or even more on the base 1 to improve the efficiency of feeding. For example, the hopper assembly 2, the taking assembly 3, the discharging assembly 4 and the separating assembly 5 are provided with two sets respectively. At this time, the feeding steps performed by the two sets of mechanisms can be consistent or inconsistent. For example, one of the two sets of mechanisms is in the taking position while the other is in the feeding position, or the processing beats of the two sets of mechanisms are staggered, so that the single magnetic materials in the two mechanisms are alternately fed. The present application is not limited in this regard.

[0089] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields based on the inventive concept of the present application and the content of the specification and drawings are included in the patent protection scope of the present application.
