Technical Field

[0001] [Cross-reference to Related Applications] This application claims the benefit of priority based on Korean Patent Application No. 10-2023-0067233 filed on May 24, 2023, and Korean Patent Application No. 10-2024-0063938 filed on May 16, 2024, and all the contents disclosed in the documents of the Korean patent applications are incorporated herein by reference.

[0002] The present invention relates to an object loading system for loading an object (or a loaded item) using a linear motor system (LMS). In particular, it relates to an object loading system capable of controlling the individual position and speed of an object to improve the supply speed.

Background Art

[0003] Generally, a secondary battery, unlike a primary battery that cannot be charged, refers to a battery that can be charged and discharged. Such secondary batteries are widely used in the field of advanced electronic devices such as mobile phones, notebook computers, and camcorders.

[0004] And the secondary battery can be classified in various ways according to the structure of the electrode assembly. As an example, the secondary battery can be classified into a stack type structure, a winding type (jelly roll type) structure, and a stack / folding type structure.

[0005] The secondary battery includes an electrode assembly, an electrolyte, and a case for housing the electrode assembly and the electrolyte. And the electrode assembly includes one or more basic units, and the basic unit has a structure in which a positive electrode and a negative electrode are alternately arranged with a separator interposed therebetween.

[0006] The manufacturing method of such a secondary battery includes a step of manufacturing a basic unit, a step of transferring and loading the basic unit, a step of manufacturing an electrode assembly by alternately arranging the basic unit and a separator, and a step of manufacturing a secondary battery by housing the electrode assembly in a case.

[0007] Here, the basic unit loading process includes a conveyor for transporting the basic units and a loading box into which the basic units falling from the conveyor are loaded.

[0008] However, conventional secondary battery manufacturing methods use conveyors, resulting in complex equipment configurations that make it impossible to control the individual position and speed of the objects, thus limiting the ability to improve the supply speed of the objects. [Overview of the project] [Problems that the invention aims to solve]

[0009] The object loading system of the present invention is to provide an object loading system that can control the individual position and speed of objects by applying a linear motor system (LMS), thereby improving the supply speed of objects. [Means for solving the problem]

[0012] The control unit can increase the power supplied to the first coil located in the acceleration section compared to the power supplied to the first coil located in the first and second sections, thereby controlling the first loading section to pass through the acceleration section at a faster speed than the first and second sections.

[0013] The control unit can increase the power supplied to the first coil located in the first section compared to the power supplied to the first coil located in the second section, thereby controlling the first loading section to pass through the first section at a faster speed than the second section.

[0014] The control unit can control the power supplied to each of the plurality of first coils so that the first loading unit passes through the acceleration section at a speed of 1501 mm / s to 3500 mm / s.

[0015] The control unit can control the power supplied to each of the plurality of first coils so that the first loading unit passes through the acceleration section at a speed of 2000 mm / s to 2500 mm / s.

[0016] The control unit can control the power supplied to the plurality of first coils so that the first loading unit passes through the first section at a speed of 1000 mm / s to 1500 mm / s.

[0017] The first stator further includes a return section connecting the second section and the first section so that the first loading section, having passed through the second section, returns to the first section, and the control unit can control the first loading section to pass through the return section at a faster speed than the first section and the second section.

[0018] The control unit can control the power supplied to the first coil located in the second section to position the first loading section at a previously set position in the second section.

[0019] The first loading unit may include a first movable element installed on the first stator, which repeatedly circulates through a first section, an acceleration section, and a second section through interaction with the magnetic field generated by the first stator; and a first shuttle fixed to the first movable element, which attracts the object in the first section and then drops the object into the second section.

[0020] The first shuttle may be detachably coupled to the first movable element.

[0021] A second stator having a circulating path that sequentially passes through a supply section to which the object is supplied and a 1-1 section opposite the first section; and one or more second loading units that repeatedly circulate between the supply section and the 1-1 section, grasping the object in the supply section and placing it in the 1-1 section, wherein the first loading unit can grasp the object placed in the 1-1 section in the first section.

The second loading section repeatedly circulates between the supply section and the 1-1 section through interaction with the magnetic field generated by the second stator, and the control unit can control the power supplied to the plurality of second coils so that the second loading section repeatedly circulates between the supply section and the 1-1 section.

[0023] The control unit can control the power supplied to the plurality of second coils so that the second loading unit passes through the supply section at a speed slower than that of the first-1 section.

[0024] The control unit can control the power supplied to the plurality of second coils so that the second loading unit passes through the supply section at a speed of 500 mm / s to 900 mm / s.

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached figures, so that they can be easily implemented by a person with ordinary skill in the art to which the present invention pertains. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Furthermore, in order to clearly illustrate the present invention, parts unrelated to the description have been omitted from the drawings, and similar parts have been denoted by similar reference numerals throughout the specification.

[0030] [Material Loading System Based on the Invention] The object loading system of the present invention has a structure to which a linear motor system (LMS) is applied. This allows for the individual attraction of each object 1 to minimize vacuum loss, and the individual transfer and speed control of each object 1, thereby improving the supply speed of the objects. In particular, the object loading system of the present invention can minimize vacuum loss and object displacement, and the positional accuracy of the objects can be precisely controlled to 0.05 to 0.1 mm, thereby greatly improving process capability and loading quality.

[0031] In other words, in the object loading system of the present invention, in the case of an adsorption section for adsorbing an object or a loading section for loading an object, the adsorption force and loading force can be increased by moving the object at a low speed or pausing, and in the case of a moving section for an object, the supply speed can be increased by moving the object at a high speed.

[0032] The object loading system of the present invention will be described in detail below with reference to the attached diagrams.

[0033] Figure 1 is a schematic process diagram showing the object loading system of the present invention, Figure 2a is a design drawing showing the object loading system of the present invention, Figure 2b is a design drawing showing the loading device included in the object loading system of the present invention, and Figure 2c is a design drawing showing the transfer device included in the object loading system of the present invention.

[0034] [Material Loading System Based on the Invention] The object loading system of the present invention includes a loading device 20 and a control unit 30, as shown in Figures 1 and 2a to 2c. The object loading system of the present invention may further include a transfer device 10.

[0035] Loading device The loading device 20 has a structure to which a linear motor system (LMS) is applied. In other words, the loading device 20 has a structure that picks up multiple objects one by one and then transports them individually.

[0036] As an example, the loading device 20 includes a first stator 21 and a first loading section 22.

[0037] The first stator 21 has a circular path that sequentially passes through the first section B, the acceleration section C, and the second section D. In particular, the first stator 21 has a structure in which a plurality of first coils are arranged at regular intervals so as to have a circular path that sequentially passes through the previously set first section B, the acceleration section C, and the second section D. Here, the first coils are provided by electromagnets.

[0038] In other words, the structure is such that multiple first coils are positioned to pass through the first section B, the acceleration section C, and the second section D, and then return to the first section B.

[0039] For example, multiple first coils are arranged in the form of a circular track, similar to the track of an athletics stadium.

[0040] On the other hand, Section 1B is the section where the object is placed, Section C is the section through which the object passes, and Section 2D is the section where the object is dropped and loaded. In particular, Section 2D is equipped with one or more loading boxes into which the object is loaded.

[0041] Figure 3 shows the first stator and first movable element of the object loading system of the present invention, and Figure 5 is a schematic diagram showing the interaction between the first stator and first movable element of the object loading system of the present invention.

[0042] On the other hand, as shown in Figures 3 and 5, the multiple first coils 211 are arranged in the direction of the circulating path and consist of electromagnets, which are electron coils. The first movable element 221, which corresponds to the first coils 211, includes a magnetic element 2211 equipped with a north pole and a south pole.

[0043] In other words, the thrust generated by the interaction of the first coil 211 and the magnetic 2211 of the first movable element 221 causes the first movable element 221 to circulate along the first coil 211 in one direction (counterclockwise when viewed from Figure 1). That is, by supplying power to the first coil through which the first movable element passes, the first movable element can be made to circulate along the first coil.

[0044] Such a first stator 21 is configured such that a first section B for positioning the object 1, an acceleration section C for moving the object 1, a second section D for loading the object 1, and a return section F connecting the second section D and the first section B are connected in the form of a circular road like a sports field track.

[0045] On the other hand, the first stator 21 further includes a base portion 213 that supports a plurality of first coils 211 so as to have a circulating path. That is, the base portion 213 has a shape similar to a track in an athletics stadium, and the plurality of first coils are supported on its outer surface to form a circulating path.

[0046] The first loading section 22 repeatedly circulates through the first section B, the acceleration section C, and the second section D, grasping objects in the first section B and loading them into the second section D. In particular, one or more, preferably multiple, first loading sections 22 are provided. Specifically, the first loading section has a structure that can attract and grasp objects.

[0047] In other words, the first loading unit 22 repeatedly cycles through the first section B, the acceleration section C, and the second section D through interaction with the magnetic field generated by the first stator 21, and after attracting the object 1 in the first section B, drops it into the second section D for loading. At this time, two or more loading points are set in the second section D, and the first loading unit 22 temporarily stops at a loading point selected by the control unit 30 before dropping the attracted object 1. Meanwhile, the dropped object 1 is sequentially loaded into the loading boxes 24 located in the second section D.

[0048] As an example, the first loading section 22 includes a first movable element 221 that is movably mounted on the first stator 21 and repeatedly cycles through a first section B, an acceleration section C, and a second section D through interaction with the magnetic field generated by the first stator 21. The first movable element 221 includes a magnetic element with a north pole and a south pole.

[0049] Figure 4 is an enlarged view showing the first and second loading sections shown in Figure 2a.

[0050] As shown in Figure 4, when current is applied to the first coil 211, an electromagnetic force acts on the first coil 211 due to its interaction with the magnetic field generated by the first stator 21. This electromagnetic force causes the first movable element 221 to receive a thrust, and the first movable element 221 moves along the first coil 211 of the first stator 21. At this time, if the current applied to the first coil 211 is large, the movement speed of the movable element increases, and if the current is small, the movement speed of the first movable element 221 decreases.

[0051] In this manner, the movement speed of the first movable element 221 can be adjusted. Specifically, the control unit 30 can adjust the movement speed of the first loading section 22 according to the section set in the first stator 21 by controlling the power supply, i.e., the magnitude of the current, supplied to the multiple coils.

[0052] For example, if the control unit 30 controls the current of the first coil 211 located in acceleration section C to be greater than a previously set value, the first loading unit 22 will pass through acceleration section C at a faster speed. Conversely, if the control unit 30 controls the current of the first coil 211 located in the first section B and the second section D to be less than a previously set value, the first loading unit 22 will pass through the first section B and the second section D at a slower speed. In particular, the control unit 30 can control the current of the first coil 211 located in the second section D to be temporarily interrupted, thereby causing the first loading unit 22 to temporarily stop in the second section D, allowing the object 1 attracted to the first loading unit 22 to drop and be loaded at the correct position.

[0053] On the other hand, the first loading section 22 further includes a first shuttle 222 which is fixed to the first movable element 221 and, after attracting the object 1 in the first section B, drops the object 1 into the second section D.

[0054] As shown in Figure 6, the first shuttle 222 includes a suction plate 2221 that attracts an object 1 placed in the first section B with suction force, an inhaler 2222 that draws in air from the suction plate to generate suction force, and a fixing member 2223 that fixes the suction plate to the first movable element 221.

[0055] On the other hand, the first shuttle 222 may be detachably coupled to the first movable element 221. For example, the first shuttle 222 and the first movable element 221 may be detachably coupled via a coupling structure of grooves and protrusions. That is, a coupling groove is formed in the first shuttle, and a coupling protrusion is formed on the first movable element that is detachably coupled to the coupling groove.

[0056] As another example, the first shuttle 222 and the first movable element 221 may be detachably coupled using an electromagnet. This allows for easy replacement of the first shuttle 222 coupled to the first movable element 221, thereby improving interchangeability and ease of maintenance and repair.

[0057] A loading device 20 having such a structure can circulate multiple first loading sections 22 so that they sequentially pass through the first section B, the acceleration section C, and the second section D along the first stator 21.

[0058] control unit The control unit 30 controls the first loading unit to repeatedly cycle through the first section, the acceleration section, and the second section. That is, the control unit 30 can adjust the moving speed of the multiple first loading units 22 as they pass through the first section B, the acceleration section C, and the second section D by controlling the power supply (i.e., current) supplied to each of the multiple first coils so that the multiple first loading units 22 repeatedly cycle through the first section B, the acceleration section C, and the second section D.

[0059] In other words, the control unit 30 can control the position and speed of each of the multiple first loading units 22, thereby individually adjusting the speed of the multiple first loading units 22 as they pass through the first section B, the acceleration section C, and the second section D, and thereby increasing the supply speed of the object 1.

[0060] Here, the control unit 30 can control the first loading unit 22 to pass through the acceleration section C at high speed. That is, the control unit 30 can control the first loading unit to pass through the acceleration section at a speed faster than the first section and the second section.

[0061] More specifically, the control unit 30 controls the power supplied to the multiple first coils 211 so that the first loading unit 22 passes through acceleration section C at a faster speed than the first section B and the second section D. That is, the control unit 30 controls the first loading unit 22 to move at a faster speed when passing through acceleration section C, and controls the first loading unit 22 to move at a slower speed when passing through the first and second sections D. As a result, the control unit 30 can increase the current supplied to acceleration section C significantly more than in the first section B and the second section D, thereby increasing the speed at which the first loading unit 22 passes through acceleration section C compared to the first and second sections, and improving the supply speed of the object 1.

[0062] Here, the control unit 30 controls the power supplied to each of the multiple first coils 211 so that the first loading unit 22 passes through the acceleration section C at a speed of 1501 mm / s to 3500 mm / s, and preferably controls the power supplied to each of the multiple first coils 211 so that it passes through at a speed of 1800 mm / s to 2500 mm / s. On the other hand, if the first loading unit 22 moves through the acceleration section C at a speed of 1500 mm / s or less, the supply speed cannot be effectively increased, and if the first loading unit 22 moves through the acceleration section C at a speed of 3500 mm / s or more, there is a problem that the object 1 attracted to the first shuttle 222 will be released. As a result, the control unit 30 controls the power supplied to each of the multiple first coils 211 so that the first loading unit 22 passes through the acceleration section C at a speed of 1501 mm / s to 3500 mm / s.

[0063] On the other hand, the control unit 30 can control the power supplied to the multiple first coils 211 so that the first loading unit 22 passes through the first section B at a speed of 1000 mm / s to 1500 mm / s. However, if the first loading unit 22 passes through the first section B at a speed of 1000 mm / s or less, there is a problem that the supply speed of the object 1 decreases, and if the first loading unit 22 passes through the first section B at a speed of 1500 mm / s or more, there is a problem that the object 1 placed in the first section B cannot be stably attracted. As a result, the control unit 30 controls the power supplied to each of the multiple first coils 211 so that the first loading unit 22 passes through the first section B at a speed of 1000 mm / s to 1500 mm / s.

[0064] On the other hand, when the first loading unit 22 drops the object 1 in the second section D, the control unit 30 can temporarily cut off the power supplied to the first coil 211 located in the second section D so that the first loading unit 22 temporarily stops. This allows the object 1 to be dropped vertically into the second section D, and as a result, the object 1 can be loaded in the correct position. Here, the control unit 30 can temporarily stop the first loading unit 22 located in the second section D for 1 to 5 seconds, preferably for 2 to 3 seconds.

[0065] Then, when the pause time is exceeded, the control unit 30 supplies power to the first coil 211 located in the second section D, causing the first loading section 22 to move back to the first section B.

[0066] On the other hand, the first stator 21 further includes a return section F connecting the second section D and the first section B so that the first loading section 22, having passed through the second section D, returns to the first section B, and the control unit 30 controls the return section to pass through at a faster speed than the first section and the second section. In other words, the control unit can control the power supplied to each of the multiple first coils 211 so that the first loading section 22 passes through the return section F at the same speed as or faster than the acceleration section C. That is, the control unit 30 can control the current supplied to the first coil 211 located in the return section F to increase so that the first loading section 22, without the object 1, returns to the first section B at a faster speed.

[0067] Here, the control unit 30 controls the power supply to the first coil 211 located in the second section D so that the first loading unit 22, which has attracted the object 1, is located at a pre-set position in the second section D. In other words, the control unit 30 can control the power supply to the first coil 211 located in the second section D to decrease so that the first loading unit 22 decelerates as it enters the second section D. This allows the first loading unit 22 to be stably positioned at a pre-set position in the second section D.

[0068] A control unit 30 having such a configuration separately controls the movement speed of the first loading unit 22 in relation to the first section B, acceleration section C, second section D, and return section F of the first stator 21. In particular, by greatly increasing the movement speed of the object 1 in the acceleration section C and return section F, the supply speed of the object 1 can be greatly improved. For example, the control unit 30 can greatly improve the supply speed of the object 1 by controlling the first loading unit 22 to move at a low speed in the first section B and second section D and at a high speed in the acceleration section C and return section F when the first loading unit 22 completes one rotation of the first stator 21.

[0069] On the other hand, the second section D includes the discharge point G. That is, when the inspection unit 23 inspects the object 1 that has been attracted to the first loading unit 22 as it passes through the acceleration section C and determines that it is defective, the control unit 30 positions the first loading unit 22 with the defective object at the discharge point G in the second section D, and the first loading unit 22 loads the defective object onto the discharge unit 25 that drops it at the discharge point G.

[0070] Here, the inspection unit 23 uses vision imaging to inspect the object 1 for any broken corners, foreign objects on the surface, etc. On the other hand, the inspection unit 23 may be a vision inspection machine.

[0071] On the other hand, the object loading system of the present invention may further include a transfer device 10 for placing the object 1 in the first section B.

[0072] Transfer device The transfer device 10 is for positioning the object 1 in the 1-1 section B-1, which is opposite the first section B, and has a structure to which a linear motor system (LMS) is applied, similar to the loading device. That is, the transfer device 10 has a structure that can pick up multiple object 1 located in the supply section A and then position them in the 1-1 section B-1.

[0073] Here, the object is supplied to supply section A by the supply device 40.

[0074] As an example, the transfer device 10 includes a second stator 11 and a second loading section 12.

[0075] The second stator 11 has a circulating path that sequentially passes through the supply section A, which is supplied with the object 1, and the 1-1 section B-1, which is opposite the first section B. In particular, the second stator 11 has a structure in which a plurality of second coils 111 are arranged at regular intervals so as to have a circulating path that sequentially passes through the supply section A, which is supplied with the object 1, and the 1-1 section B-1, which is opposite the first section B. Here, the second coils 111 are provided by electromagnets.

[0076] For example, multiple second coils 111 are connected in the form of a circular track, similar to a track in an athletics stadium, and the second loading section 12 is repeatedly circulated between supply section A and section B-1 in the same manner as the first coil 211.

[0077] Specifically, the multiple second coils 111, as shown in Figure 7, are arranged in the direction of the circulating path and include an electromagnet, which is an electronic coil. The second movable element 121, which corresponds to the second coil 111, includes a magnetic element 1211 with a north pole and a south pole.

[0078] As a result, the thrust generated by the interaction between the second coil 111 and the magnetic 1211 of the second movable element 121 causes the second movable element 121 to circulate along the second coil 111 in one direction (counterclockwise when viewed from Figure 1).

[0079] In this second stator 11, the supply section A where the object 1 is located and the 1-1 section B-1 where the object 1 is placed are connected in the form of a circular road, similar to a sports track.

[0080] Here, the second stator 11 includes an acceleration section C' between the supply section A and the first-first section B-1. That is, the second loading section 12 passes through the acceleration section C' at a faster speed than the supply section A and the first-first section B-1.

[0081] On the other hand, the second stator 11 further includes a return section F' that connects the first-first section B-1 and the supply section A. That is, the second stator 11 has the form of a sports field track in which the supply section A, the acceleration section C', the first-first section B-1, and the return section F' are sequentially connected.

[0082] Here, the second stator 11 is configured such that the second loading section 12 passes through the return section F' at the same speed as or faster than the acceleration section C'.

[0083] On the other hand, the first loading unit can attract and grasp the object 1 placed in section 1-1B-1 by the second loading unit 12 in section 1B. That is, when the second loading unit 12 is located in section 1-1B-1, the first loading unit 22 is positioned in section 1B with respect to the object 1 attracted to the second loading unit 12. Referring to Figure 4, the first loading unit and the second loading unit are positioned so that they correspond vertically with respect to the object. In this state, the suction force of the second loading unit 12 is removed, and at the same time, a suction force is generated in the first loading unit 22. As a result, the first loading unit 22 can attract the object 1 of the second loading unit 12, that is, the object placed in section 1-1.

[0084] In this manner, the second loading unit can continuously supply the object 1 to the 1-1 section B-1, and the first loading unit can continuously attract and move the object 1 that is continuously supplied to the 1-1 section B-1.

[0085] More specifically, the second loading section 12 is provided in multiple units, and through interaction with the magnetic field generated by the second stator 11, it repeatedly cycles through the supply section A, acceleration section C', 1-1 section B-1, and return section F', attracting the object 1 in the supply section A and then placing it in the 1-1 section B-1.

[0086] On the other hand, the second loading unit 12 can be temporarily stopped in the first-first section B-1 by the control unit 30, thereby enabling the first loading unit 22 to stably pick up the object 1 of the second loading unit 12 in the first section B.

[0087] As an example, the second loading section 12 includes a second movable element 121 that is movably mounted on the second stator 11 and repeatedly circulates between the supply section A and the 1-1 section B-1 through interaction with the magnetic field generated by the second stator 11. The second movable element 121 includes a magnetic element 1211 provided with a north pole and a south pole.

[0088] As shown in Figure 4, when current is applied to the second coil 111, an electromagnetic force acts on the second coil due to its interaction with the magnetic field generated by the second stator 11. This electromagnetic force causes the second movable element 121 to receive a thrust, and the second movable element 121 moves along the second coil 111 of the second stator 11. At this time, if the current applied to the second coil is large, the speed of movement of the second movable element 121 increases, and if the current is small, the speed of movement of the second movable element 121 decreases.

[0089] On the other hand, the second loading section 12 further includes a second shuttle 122 that is fixed to the second movable element 121 and, after picking up the object 1 in the supply section A, places the object 1 in the 1-1 section B-1.

[0090] Figure 8 is a cross-sectional view showing the second shuttle.

[0091] As shown in Figure 8, the second shuttle 122 includes a suction plate 1221 that attracts the object 1 placed in the supply section A with suction force, an inhaler 1222 that draws air from the suction plate 1221 to generate suction force, and a fixing member 1223 that fixes the suction plate to the second movable element 121.

[0092] In other words, once power is supplied, the second shuttle will use a solenoid valve to attract and detach objects.

[0093] On the other hand, the second shuttle 122 may be detachably coupled to the second movable element 121. For example, the second shuttle 122 and the second movable element 121 may be detachably coupled via a groove-and-projection coupling structure. As another example, the second shuttle 122 and the second movable element 121 may be detachably coupled using an electromagnet. This allows for easy replacement of the second shuttle 122 coupled to the second movable element 121, thereby improving interchangeability and ease of maintenance and repair.

[0094] On the other hand, the second shuttle 122 has the same structure as the first shuttle 222 described above, and therefore the redundant explanation will be omitted.

[0095] The control unit 30 controls the power supplied to each of the multiple second coils 111 so that the multiple second loading units 12 repeatedly circulate between supply section A and section 1-1 B-1. In particular, the control unit 30 adjusts the movement speed of each of the multiple second loading units 12 as they pass through supply section A and section 1-1 B-1.

[0096] In other words, the control unit 30 controls the power supplied to each of the multiple second coils 111 so that the second loading unit 12 passes through supply section A at a slower speed than section B-1. The control unit 30 can reduce the power supplied to the second coils 111 located in supply section A compared to the power supplied to the coils located in section B-1, thereby controlling the second loading unit 12 to pass through supply section A at a slower speed than section B-1. As an example, the control unit controls the power supplied to multiple second coils so that the second loading section passes through the supply section at a speed of 500 mm / s to 900 mm / s.

[0097] Therefore, the object loading system of the present invention can effectively move the object 1 by further including the transfer device 10, thereby greatly improving the supply speed of the object 1.
