[0001] The present invention relates to the technical field of electromagnetic heating devices, specifically to an electromagnetic heating mechanism for a laminator, and more specifically to a snap - stable electromagnetic heating mechanism for a laminator. Background Art

[0002] The essence of an electromagnetic heating mechanism is to use electromagnetic induction to perform eddy - current heating on workpieces. Its application in a laminator is reflected in the heating plate of the laminator. The laminator has a heating plate and an upper cover. The conveyor belt transports the battery module to the heating plate. After closing the cover, it is evacuated to laminate the battery module, and the heating plate can assist in processing the battery module by electromagnetic heating. For example, in the prior art, an electromagnetic induction heating device and a laminator having the same with the publication number CN114828318B include a hot pressing plate, an electromagnetic induction heater, a plurality of electromagnetic induction wires, and a controller. A plurality of annular grooves are formed on the bottom surface of the hot pressing plate along the thickness direction thereof, and a plurality of electromagnetic induction wires are respectively wound around fixed columns in a plurality of annular grooves in a one - to - one correspondence. The plurality of electromagnetic induction wires are respectively electrically connected to the electromagnetic induction heater, and the controller is electrically connected to the electromagnetic induction heater. The electromagnetic induction heating device and the laminator having the same provided by this invention can improve the heat transfer efficiency, reduce heat loss, and shorten the pre - heating time.

[0003] Another example is an electromagnetic heating coil disk with the publication number CN102573160B in the prior art. It includes a coil disk bracket having a plurality of winding portions. A magnetic strip is provided on the back of the winding portion, and an interval cavity is left between adjacent winding portions. A plurality of baffles are provided on the winding portion, and a wire groove is formed between adjacent baffles. The wire grooves on the winding portion together form a concentric circle structure. An enameled wire is wound on the wire groove, and the enameled wire changes from the wire groove of one turn to the wire groove of the adjacent turn in any one of the interval cavities. Accordingly, the winding portions on the coil disk bracket of this invention can be set to have a consistent structure, greatly simplifying the structure of the coil disk bracket and the structure of the preparation mold; when the producer performs the winding operation, it can freely realize the change - over from the wire groove of one turn to the wire groove of the adjacent turn in any one of the interval cavities between the winding portions, which is flexible and convenient.

[0004] However, although the above - mentioned prior art discloses perfect coil energization heating and its application in a laminator, since the electromagnetic coil often faces a high - temperature environment during actual use and has a higher working intensity in industrial production, the replacement and maintenance frequency are higher, and the coil needs to be repeatedly disassembled and fixed. However, the prior art does not install and fix the coil more reasonably, resulting in troublesome disassembly and installation. Summary of the Invention

[0005] The purpose of the present invention is to provide a snap - stable electromagnetic heating mechanism for a laminator, so as to solve the problem raised in the above - mentioned background technology. Although the prior art discloses perfect coil energization heating and its application in a laminator, since the electromagnetic coil often faces a high - temperature environment during actual use and has a higher working intensity in industrial production, the replacement and maintenance frequency are higher, and the coil needs to be repeatedly disassembled and fixed. However, the prior art does not install and fix the coil more reasonably, resulting in more troublesome disassembly and installation.

[0006] To achieve the above - mentioned purpose, the present invention provides the following technical solution: A snap - stable electromagnetic heating mechanism for a laminator includes a bracket snap - installed in the heating plate of the laminator, and a coil snap - installed in the groove on the upper surface of the bracket. Among them, a paddle is also arranged in the bracket on the side of the working space of the coil. The paddle is rotationally installed inside the bracket through a vertical shaft, and the paddle drives the air flow through a motor to cool the coil. At the same time, the above - mentioned air flow passes through the air holes opened on the bracket and contacts the joint surface of the coil and the air holes. The heating mechanism also includes clamping plates evenly distributed at equal angles around the center of the coil. The clamping plates are rotationally installed at the top end of the fixing plate through pin shafts, and the fixing plate is fixedly installed in the bracket.

[0007] Furthermore, the side of the bottom end of the clamping plate is set as an inclined surface, and an opening is opened on the inclined surface, and the opening is communicated with the air supply mechanism. The air supply mechanism is used to continuously generate air flow and cool the coil after the heating mechanism is powered off.

[0008] Furthermore, the air supply mechanism includes a connection mechanism and a gas source mechanism. Among them, the connection mechanism includes a connection pipe arranged inside the bracket and a trachea for connecting the gas source mechanism and the connection pipe.

[0009] Furthermore, the connection pipe is connected to the internal space of the fixing plate from below, and this internal space is also connected to the internal space of the clamping plate and the opening through a hollow pin shaft.

[0010] Furthermore, the gas source mechanism includes a horizontal cylinder arranged at the bottom end of the vertical shaft. A first valve plate for generating pressure change to transport air flow is arranged inside the horizontal cylinder, and the first valve plate continuously moves to generate an air flow transportation effect after the non - self - locking motor is powered off.

[0011] Furthermore, the first valve plate is elastically slidably connected inside the horizontal cylinder through a cross bar and a spring, and a sphere for counterweight is fixed at the outer end of the cross bar.

[0012] Furthermore, the space between the first valve plate and the vertical shaft is communicated with the hollow part in the vertical shaft through a through - hole structure, and this hollow part is also connected to a trachea rotatably connected to the bottom end of the vertical shaft.

[0013] As a further feature, the gas source mechanism comprises a gas box installed at a side position at the bottom of the bracket, wherein a horizontally distributed second valve plate is provided in the gas box, and the internal space of the gas box below the second valve plate is connected to the input end of the air pipe.

[0014] Furthermore, the upper end surface of the second valve plate is fixedly connected to the bottom end of the slide rod, and the middle section of the slide rod is vertically elastically slidably installed in the bracket through a spring, and the top end of the slide rod is connected to a metal sheet of memory alloy material, and the metal sheet is located in the air flow channel.

[0015] The beneficial effects of the present invention are as follows: the installation structure of the electromagnetic coil is redesigned, which not only can fix the coil stably and conveniently, but also can facilitate the disassembly for subsequent maintenance and replacement, and the installation structure can also use the heat generated by the electromagnetic coil during operation and electromagnetic induction to generate airflow, so that the electromagnetic heating mechanism can continue to generate airflow to fully cool the coil after power failure, which is energy-saving and environmentally friendly and reduces the damage rate of the coil, as shown in the following content:

[0016] 1. The structural design of the card plate and the opening can firstly fasten and fix the coil on the bracket from multiple directions through the rotation design of the card plate on the fixed plate. In combination with the grooves set on the surface of the bracket, the coil can be stably distributed in the bracket, and subsequent disassembly is also more convenient;

[0017] Furthermore, the structural design of the openings on the surface of the card plate enables the card plate to not only fix the coil, but also fully cool the cables in the coil through the airflow flowing through the openings, resulting in better use effect;

[0018] 2. The structural design of the horizontal cylinder and the first valve plate enables the first valve plate to move due to the driving effect of centrifugal force when the vertical shaft rotates, so that when the electromagnetic heating mechanism stops running, that is, when the vertical shaft stops rotating, the valve plate can be used to generate airflow, thereby accelerating the cooling rate of the coil after stopping, effectively improving the service life;

[0019] 3. Use materials that deform by temperature change, such as metal sheets, as the driving source for generating airflow to replace components such as horizontal cylinders that generate airflow by centrifugal force. The heat changes that are inevitably generated in the electromagnetic heating mechanism can be used as the driving force to generate airflow, which is more energy-saving and environmentally friendly and has better use effects.

Specific embodiments

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-9 , the present invention provides the following technical solutions:

[0032] Embodiment 1: In order to solve the problems existing in the prior art in this embodiment, the following solutions are disclosed. Specifically, reference can be made to Figures 1-4, including a bracket 1 snap-fitted and installed in the heating plate of the laminator, and a coil 2 snap-fitted in the groove on the upper surface of the bracket 1. Among them, a paddle 4 is also arranged on the side of the working space of the coil 2 in the bracket 1. The paddle 4 is rotationally installed inside the bracket 1 through a vertical shaft 5. The paddle 4 drives the air flow through the motor to cool the coil 2. At the same time, the above air flow passes through the air holes 6 opened in the bracket 1 and contacts the joint surface of the coil 2 and the air holes 6. This heating mechanism also includes a clamping plate 3 evenly distributed at equal angles around the center of the coil 2. The clamping plate 3 is rotationally installed at the top of the fixing plate 7 through a pin shaft, and the fixing plate 7 is fixedly installed in the bracket 1. After the coil 2 is powered on, its own heat is relatively low. However, after the workpiece to be heated is in a high-temperature state, coupled with the resistance of the coil 2 itself, the coil 2 itself will also have a relatively high temperature. Therefore, in this embodiment, not only the cable in the coil 2 is snap-fitted in the groove at the corresponding position, but also the paddle 4 is in an operating state through the operation of the motor to generate an air flow, so that the air flow can fully contact the lower surface of the coil 2 to achieve a better cooling effect. At the same time, when the coil 2 reaches the replacement cycle or suffers from heat loss, the clamping plate 3 can be rotated upward after the heating plate is opened, so that the clamping plate 3 is disengaged from the snap-fitting and fixing of the coil 2. After the replacement of the coil 2 is completed, the clamping plate 3 can be rotated and closed again. The lower end surface of the clamping plate 3 can be provided with a groove buckle structure corresponding to the cable in the coil 2, or the clamping plate 3 and the pin shaft can be set to be connected in a damped rotation or other fixable rotation connection methods.

[0033] The prior art also uses structures such as fan blades to generate air flow to cool the coil 2. However, most of them cool the lower surface of the coil 2 from the installation position of the coil 2. At the same time, in order to fully cool the upper surface of the coil 2, the following solution is also disclosed in this embodiment, that is, using an air source mechanism to cool the upper surface of the coil 2. Its main cooling method is as Figure 2 and Figures 4-5 shown. The side of the bottom end of the clamping plate 3 is set as an inclined surface, and an opening 9 is opened on the inclined surface. The opening 9 is connected to the air supply mechanism. The air supply mechanism is used to continue to generate air flow and cool the coil 2 after the heating mechanism is powered off. The air supply mechanism includes a connection mechanism and an air source mechanism. Among them, the connection mechanism includes a connection pipe 8 arranged inside the bracket 1 and a trachea 10 for connecting the air source mechanism and the connection pipe 8. The connection pipe 8 is connected to the internal space of the fixing plate 7 from below, and this internal space is also connected to the internal space of the clamping plate 3 and the opening 9 through a hollow pin shaft. When the air source mechanism operates, it will transport the air flow into the trachea 10, and through the connection of the trachea 10, the air flow will enter the connection pipe 8. The air flow passing through the internal spaces of the fixing plate 7 and the clamping plate 3 will finally be ejected from the opening 9, so as to cool the upper surface of the cable. At the same time, the trachea 10 can be set in two groups, one group is connected to the connection pipe 8, and the other group is connected to the internal space of the bracket 1, so as to use the air source mechanism to fully cool the coil 2.

[0034] Although heating will stop accordingly after power failure or the electromagnetic heating mechanism stops operating, the workpiece itself will cause the heating mechanism to be in a high heat state for a period of time after being continuously heated. Although slow cooling can also restore the electromagnetic heating component to normal temperature, being in a high temperature state for a long time will accelerate the aging of the coil 2 and related structures. Therefore, to solve this problem, the following solution is disclosed in this embodiment, which can be referred to Figures 6-7 , the air source mechanism includes a horizontal cylinder 11 provided at the bottom end of the vertical shaft 5. A first valve plate 12 for generating a pressure change to convey air flow is provided inside the horizontal cylinder 11. The first valve plate 12 continuously moves after the power failure of the non-self-locking motor to generate an air flow conveying effect. The first valve plate 12 is elastically slidably connected inside the horizontal cylinder 11 through a cross bar 13 and a spring. A sphere 14 for counterweight is fixed to the outer end of the cross bar 13. The space between the first valve plate 12 and the vertical shaft 5 is communicated with the hollow part in the vertical shaft 5 through a through hole structure, and this hollow part is also communicated with an air pipe 10 rotatably connected to the bottom end of the vertical shaft 5. During this process, when the vertical shaft 5 rotates, it will drive the horizontal cylinder 11 and related components to rotate together. Therefore, under the centrifugal force of the sphere 14, the first valve plate 12 will be pulled towards the outside by the cross bar 13. After the vertical shaft 5 stops rotating, the first valve plate 12 will slowly move back under the drive of the spring and the cross bar 13. During this process, the air flow between the first valve plates 12 will enter the internal space of the vertical shaft 5 and then enter the air pipe 10, so that air flow can continue to be generated to fully cool the coil 2 after the motor stops running.

[0035] Embodiment 2: In this embodiment, the following solution is disclosed. The main difference between this solution and the above embodiment is reflected in the air source mechanism. This is mainly because the durability of the connection between the horizontal cylinder 11 and the vertical shaft 5 is insufficient during the testing stage in the above solution. Although it can also be put into production and use, the reinforcement design will lead to an increase in cost and counterweight, making the vertical shaft 5 prone to polarization problems during high-speed rotation and having a high damage rate. Therefore, this embodiment discloses as Figures 8-9As shown in the figure, the air source mechanism includes an air box 15 installed at the side position of the bottom of the bracket 1. A second valve plate 16 horizontally distributed is arranged in the air box 15. The internal space of the air box 15 below the second valve plate 16 is communicated with the input end of the air pipe 10. The upper end surface of the second valve plate 16 is fixedly connected to the bottom end of the sliding rod 17. The middle section of the sliding rod 17 is vertically and elastically slidably installed in the bracket 1 through a spring. The top end of the sliding rod 17 is connected to a metal sheet 18 made of shape memory alloy material. The metal sheet 18 is located in the air flow channel. This content is divided into two forms. The first form is that when the air flow is flowing from the air hole 6 towards the blade 4, the hot air flow will contact the metal sheet 18. Accordingly, the metal sheet 18 deforms and upwardly pulls the second valve plate 16 to move through the sliding rod 17. After the electromagnetic heating mechanism stops operating, the metal sheet 18 will also rebound accordingly and enable the air flow below the second valve plate 16 to enter the air pipe 10, thus achieving the effect of supplying air flow. The second form is to adjust the position of the metal sheet 18 so that the pulsating magnetic field generated by the energization of the coil 2 can pass through the metal sheet 18 and generate heat through electromagnetic induction, causing the metal sheet 18 to heat up and deform. Both methods achieve the supply of air flow through thermal induction deformation, but the temperature change of the latter is more obvious and rapid, and the use effect is relatively better, and the perception of temperature change is more sensitive.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
