Description

Technical Field

[0001] This utility model belongs to the field of hollow cup motor coil production technology, and in particular relates to a high-safety, high-precision desktop motor coil hot press that is easy to load and unload materials. Background Technology

[0002] The core raw material of the hollow cup motor coil is enameled wire, which is essentially a copper conductor coated with self-adhesive insulating varnish. Its core function is to protect the copper conductor body and achieve electrical isolation between the inside of the coil and external components.

[0003] In the process of producing hollow cup motor coils using this enameled wire, the enameled wire must first be wound and flattened to obtain, as shown in the figure. Figure 1 The sheet-shaped hollow cup motor coil 200 shown in the diagram has enameled wires that are naturally separated, failing to meet the requirements for structural integrity. Therefore, the wound coil needs to undergo a hot-pressing treatment: temperature softens the self-adhesive insulating varnish on the surface of the enameled wires, while specific pressure is applied to allow the softened insulating varnish to bond between the wires, ultimately integrating the dispersed enameled wires into a structurally stable integral coil. Simultaneously, the insulating varnish ensures that the conductor portions of each copper wire remain electrically isolated, preventing short circuits.

[0004] In the prior art, a motor coil hot pressing device (authorization announcement number CN222127867U) is disclosed, including a base, a top plate fixed to the top of the base by several support rods, and a pressure plate that is movably disposed between the base and the top plate by a lifting component. A heating plate is provided on opposite sides of the base and the top plate. Two limiting rods are movably disposed on both sides of the top of the base by a linear drive component. The linear drive component is used to adjust the distance between the two limiting rods. Two connecting rods are movably disposed inside the limiting rods along both sides perpendicular to their moving direction by an adjustment mechanism. The two connecting rods extend to the outside of the limiting rods and are fixedly provided with inner support rods. The inner support rods are vertically fixed to the top of the connecting rods.

[0005] The shortcomings of the existing technology are that the pressing station of the motor coil hot pressing device is located in the middle, making it inconvenient to load materials from the side, and the whole structure is open, which makes it easy for the heating plate to cause injury (pressure or burn) to the workers, resulting in poor safety.

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] The present invention will be further described below with reference to the accompanying drawings. Example 1

[0024] Please pay close attention to the attached document. Figure 1-6This utility model discloses a high-safety, high-precision desktop motor coil hot press 100 that facilitates material handling and loading, comprising: a base plate 1, a hot pressing module 2, and a protective shell 3; the hot pressing module 2 is installed on the upper part of the base plate 1, and the protective shell 3 covers the hot pressing module 2, with the lower part of the protective shell 3 fixedly connected to the base plate 1; a material inlet / outlet 311 is provided on one side wall of the protective shell 3; the hot pressing module 2 includes: a fixing plate 21, a front support guide column 22, a rear support column 23, a lower hot pressing plate 24, a first transverse bolt 25, and a second transverse bolt 26; the lower hot pressing plate 24 is fixedly installed on the upper part of the base plate 1 near the material inlet / outlet 311; the front support guide column... There are two front support guide columns 22, which are located on both sides of the lower hot press plate 24. The upper end face of the front support guide column 22 is fixed to the lower part of the fixing plate 21, and the lower end face of the front support guide column 22 is fixed to the upper part of the base plate 1. The rear support column 23 is located on the side of the lower hot press plate 24 away from the inlet / outlet 311. The base plate 1 is provided with a first single-slit clamping hole 011, and the lower outer side of the rear support column 23 is fixed in the first single-slit clamping hole 011 by the first transverse bolt 25. The fixing plate 21 is provided with a second single-slit clamping hole 211, and the upper outer side of the rear support column 23 is fixed in the second single-slit clamping hole 211 by the second transverse bolt 26.

[0025] Compared with the prior art, the present invention has the following three beneficial effects: First, it facilitates the loading and unloading of materials. The upper surface of the lower hot press plate 24 is the coil pressing station. In this utility model, the pressing station is set as a front structure, that is, the pressing station is set close to the inlet / outlet 311, which facilitates the manual insertion and removal of the sheet-shaped hollow cup motor coil 200.

[0026] Secondly, the hot-pressing module 2 also has the advantages of good load stability, resistance to deformation, fine adjustment of relative position, and high parallelism of the pressing surfaces. Specifically, the two front support guide columns 22 and the one rear support column 23 are arranged in a triangle to ensure support stability. The upper and lower ends of the two front support guide columns 22 directly support the fixing plate 21 and the base plate 1, effectively ensuring that the distance between the fixing plate 21 and the base plate 1 does not change, guaranteeing stable support under heavy load conditions. Furthermore, the fixing plate 21 and the base plate 1 respectively clamp the upper and lower outer sides of the rear support column 23, allowing the rear support column 23 to have a certain degree of sliding freedom between itself and the clamping hole before clamping. During installation, the horizontal installation angle of the fixing plate 21 and the base plate 1 can be finely adjusted, thereby ensuring the parallelism of the two pressing surfaces that directly contact the coil in this invention, and ensuring that the insulating varnish softens synchronously and adheres consistently throughout the entire coil area.

[0027] Third, it offers high safety. The protective outer shell 3 shields the internal moving parts and high-temperature components, protecting workers and improving the safety of this invention.

[0028] According to a specific embodiment of this utility model, the hot pressing module 2 further includes: a sliding plate 27, an upper hot pressing plate 28, and a lifting and pressing drive 29; the sliding plate 27 is located between the fixed plate 21 and the lower hot pressing plate 24, and two front support guide columns 22 pass through both sides of the sliding plate 27 respectively, and the sliding plate 27 is slidably connected to the front support guide columns 22; the upper part of the upper hot pressing plate 28 is fixed to the lower part of the sliding plate 27, and the lower part of the upper hot pressing plate 28 is directly opposite to the lower hot pressing plate 24; the lifting and pressing drive 29 is installed on the fixed plate 21, and the lifting and pressing drive 29 includes a drive body 291 and a lifting drive rod 292 that passes through the fixed plate 21 and is connected to the sliding plate 27; the two front support guide columns 22 are symmetrically arranged on both sides of the lifting drive rod 292, and the lifting drive rod 292 is directly opposite to the geometric center point of the upper hot pressing plate 28.

[0029] In this embodiment, the sliding plate 27 is used to mount the upper hot press plate 28. The lifting drive rod 292 can drive the sliding plate 27 and the upper hot press plate 28 to rise and fall as a whole. The front support guide column 22 is used to guide the sliding plate 27 to ensure accuracy. The upper hot press plate 28 moves with the lifting drive rod 292 to complete the hot pressing process of the sheet-shaped hollow cup motor coil 200 located on the lower hot press plate 24. The two guide parts of the sliding plate 27 are symmetrically arranged on both sides of its power drive part, and the extension line of the power drive part is located at the geometric center of the upper hot press plate 28. This structure is conducive to balancing the force application to ensure the smooth sliding of the sliding plate 27 and further ensure the pressing accuracy.

[0030] According to a specific embodiment of the present invention, the protective shell 3 includes a front side plate 031, an inlet / outlet 311 located on the front side plate 031, and the inlet / outlet 311 is located on the side of the front side plate 031 closer to the bottom plate 1. The outer wall of the front side plate 031 is also provided with a first start button 4 and a second start button 5 located on both sides of the inlet / outlet 311. Pressing the first start button 4 and the second start button 5 at the same time controls the lifting drive rod 292 to descend.

[0031] In practical implementation, the hot press of this utility model is limited to single-person operation. The first start button 4 and the second start button 5 are connected in series and then connected to the control circuit of the lifting and pressing drive 29. This ensures that the upper hot press plate 28 can only be controlled to press down when the operator's hands are separated and the first start button 4 and the second start button 5 are pressed down at the same time. In this way, it can be ensured that when the upper hot press plate 28 presses down, the operator's hands are outside the protective shell 3, avoiding accidental operation that could injure the operator's hands and further improving safety.

[0032] Furthermore, since the forward discharge port 311, the first start button 4, and the second start button 5 are all located close to the base plate 1, the hot press of this utility model can be placed on a table to form a desktop device. Operators can sit on a stool to pick up and put down materials and press buttons, which greatly reduces the labor intensity of personnel and helps to improve the market competitiveness of this utility model.

[0033] According to a specific embodiment of this utility model, the protective shell 3 further includes: a top plate 035, a rear side plate 032, a left side plate 033, and a right side plate 034. The top plate 035, the front side plate 031, the rear side plate 032, the left side plate 033, and the right side plate 034 together form a rectangular shell shape with an opening at the bottom. The high-safety and high-precision desktop motor coil hot press 100, which facilitates the loading and unloading of materials, also includes a connecting ear plate 6 fixed to the side of the bottom plate 1. The lower part of the inner wall of the protective shell 3 is provided with an annular connecting skirt plate 7. The connecting ear plate 6 and the annular connecting skirt plate 7 are threadedly fixedly connected to each other, so that the lower part of the protective shell 3 is fixedly connected to the bottom plate 1.

[0034] In this embodiment, the protective shell 3 has an overall shell-like structure with an opening at the bottom, which has the following technical advantages: Firstly, during assembly, it can be directly fitted onto the base plate 1, enabling quick installation and disassembly, and improving the convenience of installation and maintenance. Secondly, the outer surface of the protective shell 3 is a continuous and flat structure without transverse seams, which helps to improve the simplicity and regularity of the equipment, reduce the workload and difficulty of daily maintenance, and prevent the protruding structure of the shell from scratching operators. This meets the customer's demand for a simple and regular outline of desktop equipment, further enhancing the market competitiveness of this utility model.

[0035] In this embodiment, the structure of fixed connection between the protective shell 3 and the base plate 1 is achieved by the connecting ear plate 6 located on the side of the base plate 1 and the annular connecting skirt plate 7 located on the inner side wall of the outer side of the protective shell 3. This allows the connecting part to be completely contained inside the protective shell 3, which can improve the flatness of the outer contour of the protective shell 3 and further improve the dustproof effect. More importantly, when this utility model is used in desktop equipment, this structure can further avoid scratching the operator and facilitate operation.

[0036] According to a specific embodiment of the present invention, the base plate 1 includes a first lower notch 012 and a second lower notch 013 that are respectively connected to the interior of the protective shell 3. The first lower notch 012 and the second lower notch 013 are respectively located at both ends of the base plate 1 near the rear side plate 032. The first single-slit clamping hole 011 is located between the first lower notch 012 and the second lower notch 013. The fixing plate 21 includes a first upper notch 212 and a second upper notch 213 that are respectively provided opposite to the first lower notch 012 and the second lower notch 013. The second single-slit clamping hole 211 is located between the first upper notch 212 and the second upper notch 213.

[0037] In this embodiment, the notches (first lower notch 012 and second lower notch 013) on the base plate 1 serve several functions. First, they shorten the distance between the wall of the first single-slit clamping hole 011 and the outer wall of the base plate 1, correspondingly shortening the length of the first transverse bolt 25. The notches on the base plate 1 provide the necessary transverse installation space for the first transverse bolt 25, facilitating its rapid installation. The sidewalls of the notches also serve as the mounting base for the first corner plate 8 and the second corner plate 9, providing necessary space for the operation of installation tools. Second, the notches on the base plate 1 can also serve as mounting and adjustment ports for internal components of the protective housing 3, facilitating installation and adjustment. Furthermore, the notches on the base plate 1 can also serve as heat dissipation and weight reduction ports, aiding in heat dissipation and weight reduction.

[0038] According to a specific embodiment of the present invention, the high-safety and high-precision desktop motor coil hot press 100, which facilitates material handling, also includes a first corner plate 8 and a second corner plate 9. The upper and lower ends of the first corner plate 8 and the second corner plate 9 are respectively provided with waist-shaped adjustable mounting holes 10. The upper and lower ends of the first corner plate 8 are respectively threadedly connected to the side walls of the first upper notch 212 and the first lower notch 012 through the waist-shaped adjustable mounting holes 10 at corresponding positions. The upper and lower ends of the second corner plate 9 are respectively threadedly connected to the side walls of the second upper notch 213 and the second lower notch 013 through the waist-shaped adjustable mounting holes 10 at corresponding positions.

[0039] In this embodiment, the first corner plate 8 and the second corner plate 9 are provided with waist-shaped adjustable mounting holes 10. During installation, after the fixing plate 21 and the base plate 1 are leveled, the threaded connectors are used to pass through the waist-shaped adjustable mounting holes 10 to lock and fix the upper and lower ends of the first corner plate 8 and the second corner plate 9 onto the fixing plate 21 and the base plate 1, respectively. The base plate 1, the fixing plate 21, the first corner plate 8 and the second corner plate 9 together form a rectangular frame structure, which can further improve the stability of this utility model.

[0040] According to a specific embodiment of this utility model, a left inner lip plate 11 is fixedly provided on the side of the left side plate 033 near the right side plate 034, and a right inner lip plate 12 is fixedly provided on the side of the right side plate 034 near the left side plate 033; the high-safety and high-precision desktop motor coil hot press 100, which facilitates material handling, also includes a first middle connecting plate 13 and a second middle connecting plate 14, which are respectively fixed to both sides of the fixed plate 21 by threaded connectors. The first middle connecting plate 13 and the second middle connecting plate 14 are respectively provided with a waist-shaped horizontal adjustable mounting hole 15 and a waist-shaped vertical adjustable connecting hole 16 passing through them. The first middle connecting plate 13 and the second middle connecting plate 14 are respectively fixedly connected to the left inner lip plate 11 and the right inner lip plate 12 by threaded connectors.

[0041] In this embodiment, the waist-shaped horizontally adjustable mounting hole 15 and the waist-shaped vertically adjustable connecting hole 16 cooperate to achieve adjustment in two mutually perpendicular horizontal directions to meet adjustment requirements. In specific implementation, after the fixing plate 21 and the base plate 1 are leveled, a threaded connector is used to pass through the waist-shaped horizontally adjustable mounting hole 15 and the waist-shaped vertically adjustable connecting hole 16 to fix the top of the fixing plate 21 and the inner middle of the protective shell 3 as one unit, which can further improve the stability of this utility model.

[0042] According to a specific embodiment of the present invention, the fixing plate 21 has two upper mounting grooves 214 respectively facing the two front support guide columns 22 on one side near the base plate 1. The upper end of the front support guide column 22 abuts against the bottom of the upper mounting groove 214. The front support guide column 22 is fixed to the fixing plate 21 by a threaded connector that passes through the fixing plate 21 and extends into the front support guide column 22. The base plate 1 has a lower mounting groove 014 for installing the front support guide column 22.

[0043] In this embodiment, the upper mounting groove 214 is used to receive and limit the front support guide post 22, preventing it from coming out and improving the ease of installation. It should be noted that the lower mounting groove 014 has the same function as the upper mounting groove 214.

[0044] According to a specific embodiment of this utility model, the high-safety, high-precision desktop motor coil hot press 100, which facilitates material handling, also includes a connecting lug 17 fixed on a sliding plate 27.

The snap-fit ​​groove 171 is located in the middle of the connecting lug 17, and the snap-fit ​​hole 172 is located at the top of the connecting lug 17. The snap-fit ​​hole 172 communicates with the snap-fit ​​groove 171, and both the snap-fit ​​groove 171 and the snap-fit ​​hole 172 penetrate the same side wall of the connecting lug 17. The extended end of the lifting drive rod 292 is fixedly connected with a radially protruding tension rod head 293. The lifting drive rod 292 penetrates the snap-fit ​​hole 172, and the tension rod head 293 is received in the snap-fit ​​groove 171. There is a gap between the outer side wall of the tension rod head 293 and the side wall of the snap-fit ​​groove 171, and there is a gap between the outer side wall of the tension rod head 293 and the side wall of the snap-fit ​​hole 172.

[0045] In this embodiment, the connecting lug 17 is used to realize the quick connection between the lifting drive rod 292 and the sliding plate 27. The specific description is as follows: During installation, the pull rod head is inserted into the snap-fit ​​groove 171 from the side wall of the connecting lug 17, and the snap-fit ​​hole 172 is used for the lifting drive rod 292 to be snapped in. The installation is convenient, and by setting the lateral gap, the pull rod head 293 has a certain adjustment range in the radial direction, which can accommodate a certain radial installation error and improve the smoothness of the lifting and pressing drive 29 action.

[0046] According to a specific embodiment of the present invention, a left handle 18 is fixedly connected to the outer side of the left side plate 033, and a right handle 19 is fixedly connected to the outer side of the right side plate 034.

[0047] In this embodiment, this structure is adopted for ease of handling.

[0048] More specifically, a lower heat insulation plate 021 is provided between the lower hot press plate 24 and the bottom plate 1, and an upper heat insulation plate 022 is provided between the upper hot press plate 28 and the sliding plate 27. Both the upper heat insulation plate 022 and the lower heat insulation plate 021 are graphite polystyrene boards.

[0049] More specifically, all threaded connectors in this invention are fitted with mica gaskets to isolate heat transfer during fastening, and heat insulation films are attached to the surrounding parts of the upper hot press plate 28 and the lower hot press plate 24 to prevent burns to personnel, thus providing a certain degree of safety protection.

[0050] More specifically, the front panel 031 is also equipped with a control panel 20 for controlling temperature and pressure, and the lifting and pressing drive 29 is a cylinder. Heating rods 30 and thermocouples 31 are provided on the upper hot press plate 28 and the lower hot press plate 24.

[0051] In use, this invention first connects to power and air supply. After powering on, the temperature and time for hot pressing are set.

The upper hot pressing plate 28 automatically presses down into place and holds for the set time. Then, the upper hot pressing plate 28 automatically rises back to its original position, completing the coil pressing operation. The coil is then removed through the inlet / outlet 311. The lifting and pressing drive 29 is a cylinder. Its stroke is pre-adjusted to flexibly adjust the pressing gap between the upper and lower hot pressing plates 28 and 24 to accommodate workpieces of different thicknesses. The pressing time of the lifting and pressing drive is achieved through a preset electrical control program. Example 2

[0052] Please pay close attention to the attached document. Figures 7-8This utility model also discloses a high-safety, high-precision desktop motor coil hot press that facilitates material handling. Based on the high-safety, high-precision desktop motor coil hot press 100 of Embodiment 1, this hot press adds a pressing surface cleaning unit 40. The pressing surface cleaning unit 40 includes: a rodless cylinder 401, an upper paint removal roller assembly 402 and a lower paint removal roller assembly 403 arranged vertically; the rodless cylinder 401 includes a horizontal drive body 4011 and a horizontal reciprocating slider 4012, with both ends of the horizontal drive body 4011 fixedly mounted on a first corner plate 8 and a second corner plate 9 respectively; one end of the upper paint removal roller assembly 402 and the lower paint removal roller assembly 403 in the same direction is fixedly mounted on the horizontal reciprocating slider 4012, and the horizontal reciprocating slider 4012 moves back and forth, driving the lower paint removal roller assembly 403 to move back and forth on both sides of the upper surface of the lower hot press plate 24 to clean the upper surface of the lower hot press plate 24.

[0053] Because this invention uses hot pressing during coil pressing, after a period of use, a small amount of paint from the sheet-shaped hollow cup motor coil 200 will adhere to the pressing surfaces of the upper hot pressing plate 28 and the lower hot pressing plate 24. The pressing surface cleaning unit 40 is used to clean the pressing surfaces of the upper hot pressing plate 28 and the lower hot pressing plate 24. The first corner plate 8 and the second corner plate 9 are used to fix the pressing surface cleaning unit 40.

[0054] During the cleaning operation, the upper hot platen 28 and the lower hot platen 24 are first heated to bring the paint on the pressing surfaces to a hot-melt state that facilitates removal. Then, the upper hot platen 28 is lowered to the cleaning position using the lifting and pressing drive 29. The rodless cylinder 401 drives the upper paint removal roller assembly 402 and the lower paint removal roller assembly 403 to reciprocate. During the movement, the upper paint removal roller assembly 402 and the lower paint removal roller assembly 403 contact the pressing surfaces of the upper hot platen 28 and the lower hot platen 24, respectively. The upper paint removal roller assembly 402 contacts the lower surface of the upper hot platen 28 and rotates passively, removing the paint from the pressing surfaces. After cleaning the pressing surfaces, the rodless cylinder 401 drives the upper paint removal roller assembly 402 and the lower paint removal roller assembly 403 to one side of the lower hot platen 24 to facilitate subsequent coil pressing operations.

[0055] Since the lower hot press plate 24 is a fixed structure, its relative position with the lower paint removal roller assembly 403 in the height direction is fixed. The cleaning position of the upper hot press plate 28 can be specifically referenced to the relative position of the lower hot press plate 24 and the lower paint removal roller assembly 403. The upper surface of the lower hot press plate 24 and the lower paint removal roller assembly 403 have an overlapping section in the height direction to ensure that the lower paint removal roller assembly 403 can act on the upper surface of the lower hot press plate 24 when it rolls over it. The surface layer of the paint removal roller assembly is made of a compressible material, and the overlapping section cannot be too long to avoid the lower paint removal roller assembly 403 colliding with the lower hot press plate 24 when it moves laterally.

[0056] It should be noted that the rodless cylinder 401 is an existing component that can be directly purchased. The structure of the cylinder is not described in detail in this utility model, but this does not affect the full disclosure of this utility model.

[0057] According to a specific embodiment of this utility model, the upper paint removal roller assembly 402 includes: a fixed shaft 4021, a bearing (not shown), a rotating roller 4023, and a replaceable adhesive consumable ring 4022 arranged sequentially from the inside to the outside; one end of the fixed shaft 4021 is fixedly installed on the horizontal reciprocating slider 4012, the rotating roller 4023 is rotatably connected to the fixed shaft 4021 via the bearing, and the replaceable adhesive consumable ring 4022 is detachably connected to the rotating roller 4023; the upper paint removal roller assembly 402 and the lower paint removal roller assembly 403 have the same structure; the thickness of the replaceable adhesive consumable ring 4022 is H1, the bottom of the replaceable adhesive consumable ring 4022 is lower than the upper surface of the lower hot press plate 24, and the distance between the upper surface of the lower hot press plate 24 and the bottom of the replaceable adhesive consumable ring 4022 is H2, where H2 < H1.

[0058] In this embodiment, the replaceable adhesive consumable ring 4022 can be formed by winding double-sided adhesive strips. The surface of the replaceable adhesive consumable is sticky, making it easy to remove paint from the pressing surface. The upper surface of the lower hot press plate 24 and the bottom of the replaceable adhesive consumable ring 4022 in the lower paint removal roller assembly 403 have an overlapping section in the height direction. This ensures that when the lower paint removal roller assembly 403 rolls over the upper surface of the lower hot press plate 24, the replaceable adhesive consumable ring 4022 can act on the upper surface of the lower hot press plate 24 to remove paint from it. Furthermore, the height of the overlapping section cannot exceed the thickness of the replaceable adhesive consumable ring 4022 (i.e., H2 < H1), which can prevent the lower paint removal roller assembly 403 from hitting the hot press plate 24 during lateral movement and thus failing to work smoothly.

[0059] In this embodiment, both the upper paint removal roller assembly 402 and the lower paint removal roller assembly 403 are passive rolling paint removal structures, and they can also be structures that only move (without rolling) to wipe away paint.

[0060] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can also refer to a "transmission connection," that is, a power connection through various suitable methods such as belt drive, gear drive, or sprocket drive. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
