Description

Technical Field

[0001] The present invention relates to the field of production automation, and in particular to an assembling device and an assembling method for assembling a magnetic strip and a magnetic strip frame. Background Art

[0002] When the coil on the winding drum is energized, a magnetic field is generated, which can be used for electromagnetic induction heating. A magnetic strip can be set outside the coil, and the magnetic conductivity of the magnetic strip is used to increase the magnetic field strength. In order to better fix the magnetic strip on the outside of the coil, a magnetic strip rack can be used. The magnetic strip rack can be installed on the winding drum, and the magnetic strip needs to be fixed on the magnetic strip rack.

[0003] In the prior art, such as Figure 1 As shown, the magnetic stripe rack 1100 includes a bracket body 1110 and a magnetic stripe position 1120 extending from the edge of the bracket body 1110. The magnetic stripe position 1120 is used to accommodate the magnetic stripe 1200. The bracket body 1110 is disc-shaped, and at least one magnetic stripe position 1120 is arranged on the magnetic stripe rack 1100. The angle between the magnetic stripe position 1120 and the bracket body 1110 is an obtuse angle, and the projection of the magnetic stripe position 1120 on the plane where the bracket body 1110 is located extends outward along the radial direction of the bracket body 1110. The plurality of magnetic stripe positions 1120 are evenly distributed relative to the circumference of the bracket body 1110.

[0004] The end of the magnetic stripe position 1120 adjacent to the bracket body 1110 is the magnetic stripe position first end 1121, and the end of the magnetic stripe position 1120 away from the bracket body 1110 is the magnetic stripe position second end 1122. Figure 2 As shown, after the assembly is completed, the magnetic stripe 1200 is in the working position, at which time the magnetic stripe first end 1210 of the magnetic stripe 1200 is located at the magnetic stripe first end 1121, and the magnetic stripe second end 1220 of the magnetic stripe 1200 is located at the magnetic stripe second end 1122. Before assembly, the magnetic stripe 1200 must first be placed in the pre-installation position to form a pre-installed part, such as Figure 1 As shown, at this time, the second end 1220 of the magnetic stripe is located at the first end 1121 of the magnetic stripe.

[0005] In the prior art, the magnetic strip and the magnetic strip frame need to be assembled manually, and during the assembly, the magnetic strip located at the pre-installed position needs to be pressed to the working position by manpower. In order to prevent the magnetic strip from falling off from the magnetic strip position, the magnetic strip is fixed to the magnetic strip position with an interference fit, so the staff needs to use a large force to press the magnetic strip from the pre-installed position to the working position, resulting in a large workload, high labor intensity, long time consumption, and high labor cost for assembly, resulting in low production efficiency and high production cost for assembly. Summary of the invention

[0006] In response to the problems in the above-mentioned prior art, the present application proposes an assembly device and an assembly method for assembling magnetic strips and magnetic strip racks, thereby realizing the automatic assembly of magnetic strips and magnetic strip racks, greatly reducing the workload of assembly, and helping to reduce labor intensity, time consumption and labor costs, thereby improving production efficiency and reducing production costs.

By using the assembly device, the magnetic strips can be automatically pressed from the pre-assembly position to the working position, so that the workload of assembly is greatly reduced, which is conducive to reducing labor intensity, time consumption and labor costs, thereby improving production efficiency and reducing production costs.

[0008] In one embodiment of the first aspect, the power assembly includes a power source and a transmission component, and the transmission component includes a connecting piece, and the connecting piece connects the output shaft of the power source and the oblique pressure assembly. Through this embodiment, the driving force provided by the power source can be transmitted to the oblique pressure assembly by the transmission component, driving the oblique pressure assembly to move up and down in the vertical direction, which is conducive to the oblique pressure assembly to press the magnetic strip from the pre-installed position to the working position and reset it after the pressing is completed.

[0009] In one implementation of the first aspect, a through hole is opened in the middle of the connecting piece for fixing it on the output shaft.

[0010] In one embodiment of the first aspect, the oblique pressure assembly includes an oblique pressure piece in contact with the magnetic strip, the connecting piece includes a circular connecting piece body and a connecting unit for connecting the oblique pressure piece; the connecting unit includes two connecting elements, the connecting elements extend outward from the outer wall of the connecting piece body along the radial direction of the connecting piece body, so as to connect the oblique pressure piece thereto. Through this embodiment, the connection between the oblique pressure piece and the connecting piece is achieved, which is conducive to the connecting piece driving the oblique pressure piece to move up and down, so that the oblique pressure piece can press the magnetic strip from the pre-installed position to the installation position.

[0011] In an embodiment of the first aspect, the oblique pressure piece, the connection unit and the magnetic strip correspond to each other one by one; and the plurality of connection units are evenly distributed along the circumference of the connection piece body. With this embodiment, all magnetic strips in the pre-assembled part can be pressed from the pre-assembly position to the installation position together, which is conducive to reducing assembly time and improving assembly efficiency.

[0012] In one embodiment of the first aspect, the oblique pressure piece is hinged to the connecting piece; the mounting portion further comprises an elastic member, and a connecting column is formed on the oblique pressure piece; the two ends of the elastic member are respectively fixed to the connecting columns of two adjacent oblique pressure pieces, and the elastic member is in a stretched state when the oblique pressure piece is pressed against the magnetic strip. Through this embodiment, the provision of the elastic member helps to prevent the oblique pressure piece from being offset under the force of the magnetic strip, thereby facilitating the oblique pressure piece to smoothly press the magnetic strip from the pre-installed position to the working position; and after the assembly is completed, the spring can assist the oblique pressure piece in resetting.

[0013] In one embodiment of the first aspect, the oblique pressure piece is further formed with a holding surface for contacting with and pressing down the magnetic strip. This embodiment is conducive to more effectively applying the force and avoiding stress concentration.

[0014] In an embodiment of the first aspect, the holding surface includes a first side wall and a second side wall that are perpendicular to each other. This embodiment is more conducive to achieving the adhesion of the holding surface to the rectangular magnetic strip, thereby facilitating more effective application of force and avoiding stress concentration.

[0015] In an embodiment of the first aspect, a limiting through hole is provided in the middle of the magnetic strip frame, a positioning column adapted to the limiting through hole is formed on the base, and the positioning column passes through the limiting through hole to prevent the magnetic strip frame from rotating relative to the positioning column.

[0016] In a second aspect, the present invention further provides an assembly method for assembling a magnetic strip and a magnetic strip frame, which is assembled using the assembly device of the first aspect and any embodiment thereof.

Using this assembly method, it is possible to automatically press the magnetic strip from the pre-assembly position to the working position, which greatly reduces the workload of assembly, helps reduce labor intensity, time consumption and labor costs, thereby improving production efficiency and reducing production costs.

[0017] In one embodiment of the second aspect, the oblique pressure piece is hinged to the connecting piece; during the downward movement of the oblique pressure assembly, the obtuse angle between the oblique pressure piece and the connecting piece increases, and the elastic member stretches under the action of the tension; during the upward movement of the oblique pressure assembly, the oblique pressure piece is reset under the action of the elastic force of the elastic member. Through this embodiment, the provision of the elastic member helps to prevent the oblique pressure piece from deviating under the action of the magnetic strip, thereby facilitating the oblique pressure piece to smoothly press the magnetic strip from the pre-installed position to the working position; and after the assembly is completed, the spring can assist the oblique pressure piece in resetting.

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] like Figure 3 and Figure 4 As shown, this embodiment provides an assembly device for assembling a magnetic strip 1200 and a magnetic strip rack 1100, and the assembly device includes: a base 2000, used to carry and fix a pre-assembled part 1000 consisting of a magnetic strip rack 1100 and a plurality of magnetic strips 1200; a mounting portion 3000, fixed above the base 2000, used to press the plurality of magnetic strips 1200 from the pre-assembly position to the working position, including an oblique pressing component for pressing the plurality of magnetic strips 1200 and a power component for driving the oblique pressing component to move up and down.

[0036] In the prior art, the magnetic strip 1200 and the magnetic strip frame 1100 need to be assembled manually. During assembly, the magnetic strip 1200 located at the pre-installed position needs to be pressed to the working position by manpower. In addition, since the magnetic strip 1200 and the magnetic strip frame 1100 are fixed by interference fit, the staff has to use a large force to press the magnetic strip 1200 into the working position, resulting in a large workload, high labor intensity, long time consumption, and high labor cost.

[0037] In this embodiment, the installation part 3000 of the assembly device can automatically press the magnetic strip 1200 located at the pre-installation position to the working position. The installation part 3000 includes an oblique pressure component and a power component. The power component provides power for the upward and downward movement of the oblique pressure component. The oblique pressure component directly contacts the magnetic strip 1200 and applies a force to the first end 1210 of the magnetic strip, thereby pressing the magnetic strip 1200 from the pre-installation position to the installation position.

[0038] In this embodiment, the process of pressing the magnetic stripe 1200 is implemented by an assembly device, thereby realizing the automatic assembly of the magnetic stripe 1200 and the magnetic stripe frame 1100, which greatly reduces the workload of assembly, is conducive to reducing labor intensity, time consumption and labor costs, thereby improving production efficiency and reducing production costs.

[0039] The pre-assembled part 1000 includes a plurality of magnetic strips 1200 and a magnetic strip rack 1100, and each magnetic strip 1200 is in a pre-assembled position, such as Figure 1 As shown, the second end 1220 of the magnetic stripe is located at the first end 1121 of the magnetic stripe, and the first end 1210 of the magnetic stripe is suspended. Each magnetic stripe 1200 has the same shape and size. The angles between each magnetic stripe 1120 and the bracket body 1110 are equal, and the multiple magnetic stripe 1120 are evenly distributed around the bracket body 1110.

[0040] The assembly device includes a base 2000. During the assembly process, the pre-assembled component 1000 needs to remain stationary, that is, the pre-assembled component 1000 cannot translate or rotate, so that the magnetic strip 1200 can be smoothly pressed to the working position. Therefore, the pre-assembled component 1000 needs to be fixed on the base 2000. The mounting portion 3000 is fixed above the base 2000 through the support body 4000. Figure 3 and Figure 4 As shown, the support body 4000 is also fixed on the base 2000. The support body 4000 needs to be arranged so that the oblique pressure assembly of the mounting portion 3000 is located directly above the pre-assembled component 1000.

[0041] like Figure 1 and Figure 2 As shown, the magnetic stripe holder 1100 is a central symmetrical structure, which includes a bracket body 1110 and a plurality of magnetic stripe positions 1120. The magnetic stripe positions 1120 are symmetrically distributed relative to the bracket body 1110. During the assembly process, the center line of the mounting portion 3000 needs to be on the same straight line as the center line of the magnetic stripe holder 1100, so as to avoid the mounting portion 3000 from being offset, resulting in the mounting portion 3000 being unable to smoothly contact and press down the magnetic stripe 1200.

[0042] This embodiment utilizes an assembly device to automatically press the magnetic strip 1200 from the pre-installation position to the working position, thereby greatly reducing the workload of assembly, which is beneficial to reducing labor intensity, time consumption and labor costs, thereby improving production efficiency and reducing production costs.

[0043] Optionally, the power assembly of this embodiment includes a power source and a transmission component, and the transmission component includes a connecting piece 3100, and the connecting piece 3100 connects the output shaft of the power source and the oblique pressure assembly.

[0044] Alternatively, the power source may be a pneumatic cylinder.

[0045] The transmission component drives the oblique pressure assembly to move up and down in the vertical direction under the drive of the power source, thereby pressing the magnetic strip 1200 from the pre-installed position to the working position, or driving the oblique pressure assembly to reset after the pressing is completed.

[0046] The transmission component includes a connecting piece 3100 , which connects the output shaft of the power source and the diagonal pressure assembly. The output shaft of the power source directly drives the connecting piece 3100 to move up and down in the vertical direction, so that the diagonal pressure assembly moves up and down in the vertical direction driven by the connecting piece 3100 .

[0047] The transmission component of this embodiment transmits the driving force provided by the power source to the oblique pressing assembly, thereby driving the oblique pressing assembly to move up and down in the vertical direction, which is beneficial for the oblique pressing assembly to press the magnetic strip 1200 from the pre-installed position to the working position and reset it after the pressing is completed.

[0048] like Figure 6 As shown, optionally, a through hole is opened in the middle of the connecting piece 3100 of this embodiment for fixing it on the output shaft.

[0049] The output shaft of the power source passes through the through hole in the middle of the connecting piece 3100, and the connecting piece 3100 is fixed on the output shaft of the power source, so that the extension and contraction of the output shaft in the vertical direction can drive the connecting piece 3100 to move vertically downward and upward.

[0050] like Figure 7 As shown, optionally, the oblique pressure assembly of this embodiment includes an oblique pressure piece 3200 in contact with the magnetic strip 1200, and the connecting piece 3100 includes a circular connecting piece body 3110 and a connecting unit 3120 for connecting the oblique pressure piece 3200; the connecting unit 3120 includes two connecting elements 3121, and the connecting elements 3121 extend outward from the outer wall of the connecting piece body 3110 along the radial direction of the connecting piece body 3110 to connect the oblique pressure piece 3200 therein.

[0051] The oblique pressure piece 3200 is in direct contact with the magnetic strip 1200 and applies a force to the first end 1210 of the magnetic strip, thereby pressing the magnetic strip 1200 from the pre-installed position to the installed position. The connecting unit 3120 of the connecting piece 3100 is used to connect the oblique pressure piece 3200, that is, to connect the oblique pressure piece 3200 to the connecting piece 3100. Therefore, when the connecting piece 3100 moves up and down, it will drive the oblique pressure piece 3200 to move up and down.

[0052] The connecting piece 3100 of this embodiment includes a connecting piece body 3110 and a connecting unit 3120. The connection between the oblique pressure piece 3200 and the connecting piece 3100 is achieved through the connecting unit 3120, which is beneficial for the connecting piece 3100 to drive the oblique pressure piece 3200 to move up and down, so that the oblique pressure piece 3200 can press the magnetic strip 1200 from the pre-installed position to the installation position.

[0053] Optionally, the connecting piece body 3110 may also be a regular polygon.

[0054] Optionally, the oblique pressure pieces 3200 , the connection units 3120 and the magnetic strips 1200 of this embodiment correspond one to one; and the plurality of connection units 3120 are evenly distributed along the circumference of the connection piece body 3110 .

[0055] The oblique pressure pieces 3200, the connecting units 3120 and the magnetic strips 1200 correspond one to one, that is, the number of the oblique pressure pieces 3200 in the oblique pressure assembly is equal to the number of the magnetic strips 1200 in the pre-assembled part 1000 and their positions correspond, so that under the drive of the power assembly, multiple oblique pressure pieces 3200 can move up and down at the same time, thereby being able to press all the magnetic strips 1200 in the pre-assembled part 1000 from the pre-assembly position to the installation position together.

[0056] In the prior art, the magnetic strips 1200 and the magnetic strip rack 1100 need to be assembled manually. During assembly, the magnetic strips 1200 located at the pre-installation position need to be pressed one by one to the working position by manpower. However, the oblique pressing assembly in this embodiment can press all the magnetic strips 1200 in the pre-installation part 1000 from the pre-installation position to the installation position together by using a plurality of oblique pressing pieces 3200, which is conducive to reducing assembly time and improving assembly efficiency.

[0057] The multiple connection units 3120 are evenly distributed along the circumference of the connection piece body 3110, and the multiple magnetic stripe positions 1120 are also evenly distributed relative to the circumference of the bracket body 1110, which is beneficial to ensure that each inclined pressure piece 3200 can contact the corresponding magnetic stripe 1200 without misalignment.

[0058] Optionally, the number of the oblique pressure pieces 3200 , the number of the connection units 3120 , and the number of the magnetic strips 1200 are all six.

[0059] This embodiment arranges the oblique pressing pieces 3200, the connecting units 3120 and the magnetic strips 1200 in one-to-one correspondence, so that all the magnetic strips 1200 in the pre-assembled part 1000 can be pressed together from the pre-assembly position to the installation position, which is beneficial to reducing assembly time and improving assembly efficiency.

[0060] Optionally, the assembly device may also be equipped with only one inclined pressing plate 3200. After a magnetic strip 1200 is pressed from the pre-installation position to the working position and the inclined pressing plate 3200 is reset, the inclined pressing plate 3200 can be rotated relative to the center line of the mounting portion 3000 until the inclined pressing plate 3200 corresponds to the position of another magnetic strip 1200 to be assembled, and the press-feed assembly is performed again. The process is repeated until all magnetic strips 1200 are pressed to the mounting position.

[0061] Optionally, the oblique pressure piece 3200 of this embodiment is hinged to the connecting piece 3100; Figure 5 As shown, the mounting portion 3000 also includes an elastic member, and a connecting column 3210 is formed on the oblique pressure piece 3200; both ends of the elastic member are respectively fixed on the connecting columns 3210 of two adjacent oblique pressure pieces 3200, and when the oblique pressure piece 3200 is pressed against the magnetic strip 1200, the elastic member is in a stretched state.

[0062] Optionally, the oblique pressure assembly may further include a fixing member, a first through hole is opened on the connecting element 3121, and a second through hole is opened on the oblique pressure sheet 3200. The fixing member may pass through the first through hole and the second through hole as a hinge axis to hinge the oblique pressure sheet 3200 with the connecting element 3121, so that the oblique pressure sheet 3200 can rotate relative to the connecting element 3121.

[0063] like Figure 7 As shown, in order to expand the range of the rotatable angle of the oblique pressure piece 3200 relative to the connecting element 3121, an avoidance surface 3230 is further formed on the oblique pressure piece 3200 for avoiding the connecting piece body 3110 when the oblique pressure piece 3200 rotates.

[0064] In the process of pressing the magnetic strip 1200 from the pre-loading position to the working position, in order to prevent the inclined pressing piece 3200 from being offset under the force of the magnetic strip 1200, the elastic part is in a stretched state, so that the angle between the inclined pressing piece 3200 and the connecting piece 3100 cannot increase freely, thereby limiting the inclined pressing piece 3200, which is conducive to the inclined pressing piece 3200 to smoothly press the magnetic strip 1200 from the pre-loading position to the working position.

[0065] After the assembly is completed, the oblique pressure piece 3200 and the magnetic strip 1200 are separated from each other, and the spring is reset under the action of the elastic force, thereby driving the oblique pressure piece 3200 to reset, thereby preparing for the next use of the assembly device.

[0066] This embodiment uses a spring to prevent the inclined pressure piece 3200 from shifting under the force of the magnetic strip 1200, thereby facilitating the inclined pressure piece 3200 to smoothly press the magnetic strip 1200 from the pre-installed position to the working position, and after the assembly is completed, the spring can assist the inclined pressure piece 3200 in resetting.

[0067] like Figure 7As shown, optionally, the oblique pressure piece 3200 of this embodiment is further formed with a holding surface 3220 for contacting the magnetic strip 1200 and pressing down the magnetic strip 1200 .

[0068] During the pressing process, the holding surface 3220 needs to fit with the magnetic strip 1200 so as to apply the force more effectively and avoid stress concentration, so that the assembly device can press the magnetic strip 1200 into the working position with less force, which is beneficial to saving energy and avoiding damage to the magnetic strip 1200 and the oblique pressure sheet 3200 caused by stress concentration.

[0069] like Figure 7 As shown, optionally, the holding surface 3220 of this embodiment includes a first side wall 3221 and a second side wall 3222 that are perpendicular to each other.

[0070] The magnetic stripe 1200 is in the shape of a cuboid, and the mutually perpendicular first side wall 3221 and second side wall 3222 can respectively fit with two adjacent side surfaces of the magnetic stripe 1200 , thereby achieving fitting of the holding surface 3220 with the magnetic stripe 1200 .

[0071] like Figure 1 and Figure 2 As shown, optionally, a limited position through hole 1111 is provided in the middle of the magnetic strip frame 1100 of this embodiment. Figure 4 As shown, a positioning column 2100 adapted to the limiting through hole 1111 is formed on the base 2000 , and the positioning column 2100 passes through the limiting through hole 1111 to prevent the magnetic strip frame 1100 from rotating relative to the positioning column 2100 .

[0072] During the assembly process, the pre-assembled component 1000 needs to remain stationary, that is, the pre-assembled component 1000 cannot translate or rotate, so that the magnetic strip 1200 can be smoothly pressed to the working position. Therefore, the pre-assembled component 1000 needs to be fixed on the base 2000. One of the main functions of the positioning column 2100 is to fix the pre-assembled component 1000 on the base 2000, thereby preventing the pre-assembled component 1000 from translating or rotating relative to the base 2000.

[0073] Another main function of the positioning column 2100 is to achieve the vertical correspondence between the position of the oblique pressure piece 3200 and the position of the magnetic strip 1200. The position of the mounting portion 3000 is fixed, and the mounting position of the pre-assembled part 1000 on the base 2000 also needs to be fixed, so the cross-sectional shape of the positioning column 2100 needs to be designed to ensure that the position of the oblique pressure piece 3200 corresponds to the position of the magnetic strip 1200.

[0074] The positioning column 2100 of this embodiment can prevent the pre-assembled component 1000 from translating or rotating relative to the base 2000, and can also ensure that the position of the inclined pressure piece 3200 corresponds to the position of the magnetic strip 1200.

[0075] This embodiment also provides an assembly method for assembling the magnetic strip 1200 and the magnetic strip frame 1100, which is assembled using the above-mentioned assembly device. The assembly method includes the following steps: fixing the pre-assembled component 1000 on the base 2000; the power component drives the oblique pressure component to move downward until the magnetic strip 1200 is pressed from the pre-assembly position to the working position; the power component drives the oblique pressure component to move upward to reset the oblique pressure component.

[0076] This assembly method can automatically press the magnetic strip 1200 from the pre-installation position to the working position, which greatly reduces the workload of assembly, helps to reduce labor intensity, time consumption and labor costs, thereby improving production efficiency and reducing production costs.

[0077] Optionally, the oblique pressure piece 3200 of the present embodiment is hinged to the connecting piece 3100; during the downward movement of the oblique pressure assembly, the obtuse angle between the oblique pressure piece 3200 and the connecting piece 3100 increases, and the elastic member stretches under the action of the tension; during the upward movement of the oblique pressure assembly, the oblique pressure piece 3200 is reset under the action of the elastic force of the elastic member.

[0078] This embodiment uses a spring to prevent the inclined pressure piece 3200 from shifting under the force of the magnetic strip 1200, thereby facilitating the inclined pressure piece 3200 to smoothly press the magnetic strip 1200 from the pre-installed position to the working position; and after the assembly is completed, the spring can assist the inclined pressure piece 3200 in resetting, thereby preparing for the next use of the assembly device.

[0079] Optionally, the inclined pressure pieces 3200 of this embodiment correspond one-to-one to the magnetic strips 1200. During the up and down movement of the inclined pressure assembly, the displacements of multiple inclined pressure pieces 3200 are the same and the multiple magnetic strips 1200 corresponding thereto are pressed one-to-one from the pre-loading position to the working position synchronously.

[0080] This embodiment arranges the oblique pressing pieces 3200, the connecting units 3120 and the magnetic strips 1200 in one-to-one correspondence, so that all the magnetic strips 1200 in the pre-assembled part 1000 can be pressed together from the pre-assembly position to the installation position, which is beneficial to reducing assembly time and improving assembly efficiency.
