[0003] The main purpose of this invention is to propose an automatic feeding device and production line, which aims to solve the problem of feeding devices damaging raw materials.

[0004] To achieve the above objectives, the present invention proposes an automatic feeding device for use in a production line, wherein the production line is provided with a feeding position, comprising:

[0005] Mounting base;

[0006] A material-receiving structure, comprising an inner core and an outer cylinder, the outer cylinder being disposed on the mounting base, the inner core having a magnetic component, the inner core being slidably inserted into the outer cylinder along the axial direction of the outer cylinder, and the outer cylinder having a material-receiving wall; and

[0007] A magnetic drive structure is provided, which is connected to the inner core drive to drive the inner core to slide toward or away from the material receiving wall.

[0008] In one embodiment, the mounting base includes a first mounting plate and a second mounting plate spaced apart from each other. The outer cylinder is movably mounted on the first mounting plate and the second mounting plate. The second mounting plate is located close to the material receiving wall. The outer circumferential surface of the outer cylinder is provided with a mounting protrusion located between the first mounting plate and the second mounting plate. An elastic element is provided between the mounting protrusion and the first mounting plate.

[0009] In one embodiment, the second mounting plate has an alignment protrusion on the side opposite to the elastic member to cooperate with the alignment groove of the feeding position.

[0010] In one embodiment, the material taking structure is further provided with a positioning protrusion, which is provided on the end face of the inner core and the material taking wall opposite to each other. The material taking wall is provided with a clearance through hole corresponding to the positioning protrusion, and the positioning protrusion is used to insert the positioning hole of the raw material.

[0011] In one embodiment, a plurality of positioning protrusions are provided at circumferential intervals along the inner core, and the material picking wall is provided with an avoidance through hole corresponding to each positioning protrusion.

[0012] In one embodiment, the free end of the positioning protrusion is conical.

[0013] In one embodiment, the magnetic component at least partially protrudes from the end face of the inner core, and the material receiving wall is provided with a magnetic clearance opening corresponding to the protruding section of the magnetic component.

[0014] In one embodiment, the material picking structure is provided in multiple ways, and the multiple material picking structures are spaced apart on the mounting base.

[0017] The technical solution of this utility model uses a magnetic drive structure to drive the inner core to slide towards or away from the material picking wall, thereby causing the magnetic component to slide towards or away from the material picking wall. This allows the material picking wall to attract the raw material, or for the magnetism of the magnetic component to gradually dissipate from the raw material, so that the raw material falls into the feeding position. This feeding device has a simple structure and will not squeeze the raw material or cause the raw material to bend due to excessive suction, thus avoiding the problem of the feeding device damaging the raw material.

[0031] Currently, the market generally uses grippers or vacuum suction cups for feeding. Grippers can easily squeeze the raw material 500, while suction cups can easily damage the raw material 500 due to excessive suction.

[0032] To address the problem of raw material damage caused by feeding devices, this utility model proposes an automatic feeding device.

[0033] Please see Figure 1 and Figure 4 In one embodiment of this utility model, the automatic feeding device is used in a production line. The production line is provided with a feeding position. The automatic feeding device includes a mounting base 100, a material picking structure 200, and a magnetic drive structure 300. The material picking structure 200 includes an inner core 210 and an outer cylinder 220. The outer cylinder 220 is disposed on the mounting base 100. The inner core 210 is provided with a magnetic element 230. The inner core 210 is slidably inserted into the outer cylinder 220 along the axial direction of the outer cylinder 220. The outer cylinder 220 has a material picking wall 221. The magnetic drive structure 300 is drivenly connected to the inner core 210 to drive the inner core 210 to slide towards or away from the material picking wall 221.

[0034] The technical solution of this utility model uses a magnetic drive structure 300 to drive the inner core 210 to slide towards or away from the material picking wall 221, thereby causing the magnetic component 230 to slide towards or away from the material picking wall 221. This allows the material picking wall 221 to attract the raw material 500, or to gradually reduce the magnetism of the magnetic component 230 from the raw material 500, so that the raw material falls into the feeding position. This feeding device has a simple structure and will not squeeze the raw material 500 or bend it due to excessive attraction, thus avoiding the problem of the feeding device damaging the raw material 500.

[0035] Specifically, when the automatic feeding device picks up material, the magnetic drive structure 300 drives the inner core 210 to slide towards the material picking wall 221, thereby causing the magnetic component 230 to slide towards the material picking wall 221, so that the raw material 500 can be attracted to the material picking wall 221. When the automatic feeding device discharges material, the magnetic drive structure 300 drives the inner core 210 to move away from the material picking wall 221, thereby causing the magnetic component 230 to move away from the material picking wall 221, so that the magnetism of the magnetic component 230 gradually dissipates from the raw material 500, allowing the raw material 500 to fall into the discharge position. This feeding device will not squeeze the raw material 500, thus preventing damage to the raw material 500 and ensuring the yield of the feeding.

[0036] In this scheme, the raw material 500 is a magnetic raw material 500 made of a material that can be attracted by the magnetic component 230, such as, but not limited to, the material itself having ferromagnetism, the material containing ferromagnetic components, the material having magnetic additives added, or containing magnetic particles, etc.

[0037] In this embodiment, the production line is equipped with a workbench, which has a material picking position and a material placing position. The automatic feeding device is used to place the raw material 500 from the material picking position to the material placing position, so that the processing tools can process the raw material 500 into finished products.

[0038] In this embodiment, optionally, the production line also includes a sheet stacking device, which neatly stacks the scattered sheets at the picking position so that multiple sheets are coaxially stacked to form raw material, while the automatic feeding device feeds the raw material from the picking position to the discharging position.

[0039] Reference Figures 1 to 5 Optionally, the mounting base 100 includes a first mounting plate 110 and a second mounting plate 120 spaced apart from each other. The outer cylinder 220 is movably mounted on the first mounting plate 110 and the second mounting plate 120. The second mounting plate 120 is located close to the material receiving wall 221. The outer circumferential surface of the outer cylinder 220 is provided with a mounting protrusion 222 located between the first mounting plate 110 and the second mounting plate 120. An elastic element 240 is provided between the mounting protrusion 222 and the first mounting plate 110. It can be understood that... The outer cylinder 220 is movably mounted on the first mounting plate 110 and the second mounting plate 120, and an elastic element 240 is provided between the mounting protrusion 222 and the first mounting plate 110. This allows the outer cylinder 220 to have an elastic buffering effect, for example, but not limited to, when the outer cylinder 220 just touches the raw material 500, the outer cylinder 220 can elastically avoid contact with the raw material 500 and the outer cylinder 220, thereby reducing the probability of damage to the raw material 500 and the material handling structure 200. Of course, this solution is not limited to this. In other embodiments, the elastic element can also be provided between the mounting protrusion 222 and the second mounting plate 120, as long as the outer cylinder 220 can provide an elastic buffering effect.

[0040] The elastic element 240 is configured as a spring because springs have excellent elastic deformation capabilities, can withstand external forces within a certain range and maintain their shape, and can quickly return to their original shape when the external force disappears. This helps the outer cylinder 220 to return to its original state in a timely manner while elastically buffering and avoiding external forces, so that the outer cylinder 220 can better cooperate with the raw material 500 and the structure of the discharge position (such as the wall of the discharge trough). Of course, this solution is not limited to this. In other embodiments, the elastic element 240 can also be configured as a silicone pad, etc., as long as it can make the outer cylinder 220 elastically buffer and return to its original state.

[0041] Optionally, the second mounting plate 120 is provided with a positioning protrusion 121 on the side opposite to the elastic member 240 to cooperate with the positioning groove of the feeding position. It can be understood that the positioning cooperation between the positioning protrusion 121 and the positioning groove of the feeding position can increase the accuracy of the raw material 500 being placed in the preset placement position and reduce the probability of the raw material 500 deviating from the preset placement position.

[0042] Furthermore, in this embodiment, multiple alignment protrusions 121 are provided, and the alignment protrusions 121 are at least located at two opposite corners of the second mounting plate 120, which can increase the positioning effect of the mounting base 100.

[0043] Optionally, in this embodiment, four alignment protrusions 121 are provided, and the four alignment protrusions 121 are respectively located at the four corners of the second mounting plate 120. Of course, this solution is not limited to this. In other embodiments, only two alignment protrusions 121 may be provided, and the two alignment protrusions 121 are respectively located at opposite corners of the second mounting plate 120.

[0044] Furthermore, in this embodiment, there are four alignment protrusions 121, and the alignment protrusions 121 on the same side have different shapes, which can achieve the effect of preventing mistakes.

[0045] Furthermore, the free end of the alignment protrusion 121 is conical. Specifically, the cross-section of the alignment protrusion 121 decreases in the direction from the end face to the second mounting plate 120. This allows the mounting base 100 to move even if the alignment protrusion 121 slightly deviates from the alignment groove, thereby allowing the alignment protrusion 121 to be inserted into the alignment groove.

[0046] Furthermore, the material taking structure 200 is also provided with a positioning protrusion 211. The positioning protrusion 211 is provided on the end face of the inner core 210 and the material taking wall 221 opposite to each other. The material taking wall 221 is provided with a clearance through hole corresponding to the positioning protrusion 211. The positioning protrusion 211 is used to insert the positioning hole of the raw material 500. It is understood that the clearance through-hole is aligned with the positioning hole of the raw material 500, then the outer cylinder 220 is driven to abut against the material sheet, and the magnetic drive structure 300 is controlled to drive the inner core 210 to move towards the material receiving wall 221. This causes the positioning protrusion 211 to sequentially pass through the clearance through-hole and the positioning hole of the material sheet. Simultaneously, the raw material 500 is attracted to the material receiving wall 221. The positioning protrusion 211, inserted into the positioning hole of the raw material 500, achieves the positioning of the raw material 500, preventing it from deviating from the preset attraction position when attracted to the material receiving wall 221. This improves the accuracy of the raw material 500 being placed in the preset placement position on the feeding position. Furthermore, the positioning protrusion 211 prevents the position of the raw material 500 from shifting during collisions or vibrations. Of course, this solution is not limited to this; in other embodiments, the positioning protrusion 211 may not be provided.

[0047] Optionally, multiple positioning protrusions 211 are spaced apart circumferentially along the inner core 210, and the material-receiving wall 221 is provided with a clearance through hole corresponding to each positioning protrusion 211; this can improve the positioning effect. Of course, this solution is not limited to this. In other embodiments, there may be only one positioning protrusion 211, or multiple positioning protrusions 211 may be spaced apart circumferentially along the inner core 210, and the material-receiving wall 221 may be provided with an annular clearance through hole corresponding to multiple positioning protrusions 211.

[0048] In this embodiment, the automatic feeding device further includes a robotic arm, with a mounting base 100 disposed on the robotic arm. The robotic arm can drive the mounting base 100 to operate, for example, but not limited to, driving the mounting base 100 to move the outer cylinder 220 against the raw material 500, or driving the mounting base 100 to move the material-picking structure 200 from the material-picking position to the material-discharging position. Of course, this solution is not limited to this. In other embodiments, the automatic feeding structure may also include an axial drive structure, which is driven and connected to the base to drive the material-picking structure 200 to move along the X-axis, Y-axis, and Z-axis, thereby allowing the outer cylinder 220 to abut against the material sheet, or moving the material-picking structure 200 from the material-picking position to the material-discharging position.

[0049] Reference Figure 5 and Figure 6Optionally, the free end of the positioning protrusion 211 is conical. Specifically, the cross-section of the positioning protrusion 211 gradually decreases in the direction from the end face to the inner core 210, so that even if the positioning protrusion 211 deviates slightly from the positioning hole of the raw material 500, the free end of the positioning protrusion 211 can guide the positioning protrusion 211 into the positioning hole of the raw material 500. Of course, this solution is not limited to this. In other embodiments, the free end of the positioning protrusion 211 may also be pyramidal.

[0050] Furthermore, the magnetic component 230 protrudes at least partially from the end face of the inner core 210, and the material receiving wall 221 is provided with a magnetic clearance opening corresponding to the protruding section of the magnetic component 230. This can increase the magnetic strength of the magnetic component 230 acting on the raw material 500 and increase the stability of the raw material 500 adhering to the material receiving wall 221.

[0051] Optionally, multiple material-grabbing structures 200 are provided, and the multiple material-grabbing structures 200 are spaced apart on the mounting base 100. The automatic feeding device also includes a transmission base 400. The inner cores 210 of the multiple material-grabbing structures 200 are respectively connected to the transmission base 400, and the magnetic drive structure 300 is drivenly connected to the transmission base 400. It can be understood that by providing multiple material-grabbing structures 200, several sets of raw materials 500 can be picked up at one time, which is beneficial to improving the feeding efficiency. Moreover, by utilizing the cooperation between the transmission base 400 and the magnetic drive structure 300, the synchronous picking and unloading of multiple material-grabbing structures 200 can be realized.

[0052] Furthermore, the magnetic drive structure 300 includes a motor, a fixed base, and a telescopic rod. The telescopic rod is located between the fixed base and the transmission base 400, and the motor is mounted on the fixed base. The output shaft of the motor is connected to the transmission base 400. This magnetic drive structure 300 has a simple structure, and the use of the telescopic rod between the fixed base and the transmission base 400 helps to increase the stability of the inner core 210 during operation. Of course, this solution is not limited to this. In other embodiments, the magnetic drive structure 300 can also be configured as other drive structures, as long as they can drive the inner core 210 to move.

[0053] In this embodiment, a material feeding groove is provided on the worktable, and a preset placement position is formed in the material feeding groove.

[0054] Furthermore, the outer circumference of the material-receiving wall 221 is smaller than the outer diameter of the raw material 500. This avoids interference between the material-receiving wall 221 and the wall of the discharge trough, and also prevents the material-receiving wall 221 from colliding with the wall of the discharge trough, thus preventing the material-receiving wall 221 from damaging the discharge trough. Of course, this solution is not limited to this. In other embodiments, the outer circumference of the material-receiving wall 221 can also be equal to the outer diameter of the raw material 500.

[0055] This utility model also proposes a production line, which includes an automatic feeding device. The specific structure of the automatic feeding device is as described in the above embodiments. Since this production line 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.

[0056] Optionally, in this embodiment, the production line includes a shift plate, which is provided with a finished product picking section and a raw material feeding section. A first mounting plate 110 is formed on the raw material feeding section, and the finished product picking section is provided with a finished product picking device. The shift plate is driven to connect with a robotic arm to drive the finished product picking section and the raw material feeding section to interchange positions. Thus, after the raw material 500 is processed into a finished product, the robotic arm can drive the finished product picking section and the raw material feeding section of the shift plate to interchange positions, thereby using the finished product picking device on the finished product picking section to pick up the finished product. This can improve the processing efficiency of the production line while reducing the setup of the drive structure for the finished product picking device.

[0057] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
