Description

Technical Field

[0001] This utility model belongs to the field of hollow cup motor coil production technology, and in particular relates to an anti-misalignment coil flattening execution module for a hollow cup motor coil flattening device. Background Technology

[0002] In the production process of coreless motors, coil fabrication is a crucial step, encompassing multiple processes such as winding, flattening, wire end removal, and tinning. Among these, the flattening process plays a decisive role in the final performance and quality of the motor. After the enameled wire is wound on the winding die to form a hollow coil with multiple wire ends (also known as "electrode ends"), it must be flattened into a flat shape before proceeding to subsequent processes such as wire end removal and tinning.

[0003] In the prior art, Chinese patent CN203708033U discloses a coil flattening mechanism in the manufacturing process of motor coils. This mechanism includes a clamping component for gripping a hollow coil, a flattening component for flattening the hollow coil, and a moving component that drives the clamping component to a winding die. The flattening process is as follows: a first and a second flattening plate respectively adhere to the two opposite outer sides of the hollow coil, and while the first and second flattening plates move back and forth, they also move closer to each other to flatten the hollow coil located between the first and second flattening plates into a flat shape.

[0004] The shortcoming of existing technology is that, during the flattening process of hollow coils, there is a lack of effective positioning measures for the coil bundle and wire ends. During the flattening process, the position of the coil bundle and wire ends is prone to slippage and misalignment. Once slippage occurs, the position of the coil bundle and wires deviates from the predetermined position and shape, resulting in a defective product. In other words, when using the aforementioned coil flattening mechanism to flatten hollow coils, it is difficult to ensure the stability of the flattening effect, leading to a high scrap rate.

[0005] Therefore, it is necessary to provide a new anti-misalignment coil flattening execution module for a hollow cup motor coil flattening device to solve the above-mentioned technical problems. Summary of the Invention

[0048] 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.

[0049] The following is in conjunction with the appendix Figure 1-8 The present invention provides a further description of the anti-misalignment coil flattening execution module for a hollow cup motor coil flattening device.

[0050] Please refer to this carefully. Figure 1-4This utility model discloses an anti-misalignment coil flattening execution module for a hollow cup motor coil flattening device, used to flatten a wound hollow coil 100 to obtain a flat, regular wire block 200. The wound hollow coil 100 includes a first sidewall 101 and a second sidewall 102 arranged opposite to each other. The anti-misalignment coil flattening execution module for the hollow cup motor coil flattening device includes a first wire-twisting assembly 1 and a second wire-twisting assembly 2 arranged opposite to each other. The first wire-twisting assembly 1 includes: a first wire-twisting plate 11, a first inner pressure plate 12, and a first inner pressure plate cross-linear drive 13. The second wire-twisting assembly 2 includes: a second wire-twisting plate 21, a second inner pressure plate 22, and a second inner pressure plate cross-linear drive 23. The first wire-twisting plate 11 and the second wire-twisting plate 21 are arranged opposite to each other, and the anti-misalignment coil flattening execution module for the hollow cup motor coil flattening device also includes an opening and closing mechanism for driving the first wire-twisting plate 11 and the second wire-twisting plate 21 to open and close. Drive assembly 3; a first inner pressure plate 12 is mounted on a first washboard 11 via a first inner pressure plate cross linear drive 13. The first washboard 11 is rectangular in shape. The first inner pressure plate cross linear drive 13 is used to drive the first inner pressure plate 12 to move along the length and width directions of the first washboard 11, respectively. A second inner pressure plate 22 is mounted on a second washboard 21 via a second inner pressure plate cross linear drive 23. The second washboard 21 is rectangular in shape. The second inner pressure plate cross linear drive 23 is used to drive the second inner pressure plate 22 to move along the length and width directions of the second washboard 21, respectively. The first inner pressure plate 12 and the second inner pressure plate 22 are respectively disposed between the first washboard 11 and the second washboard 21. The first inner pressure plate 12 and the first washboard 11 are respectively used to press and clamp the inner and outer sides of the first sidewall 101. The second inner pressure plate 22 and the second washboard 21 are respectively used to press and clamp the inner and outer sides of the second sidewall 102.

[0051] like Figure 4 In this embodiment, the first inner pressure plate cross linear drive 13 and the second inner pressure plate cross linear drive 23 can extend and retract along the X-axis (the length direction of the first washboard 11) and the Y-axis (the width direction of the first washboard 11), respectively. The first inner pressure plate cross linear drive 13 and the second inner pressure plate cross linear drive 23 can be existing cross linear drive modules that can be directly purchased, or they can be composed of two linear drive modules combined. Since the first inner pressure plate 12 is mounted on the first washboard 11, when the first inner pressure plate cross linear drive 13 is stationary, the first inner pressure plate 12 moves synchronously with the first washboard 11; similarly, since the second inner pressure plate 22 is mounted on the second washboard 21, when the second inner pressure plate cross linear drive 23 is stationary, the second inner pressure plate 22 moves synchronously with the second washboard 21.

[0052] This invention relates to a flattening process, the preceding step of which is coil winding. After coil winding, a hollow coil 100 is fitted onto a hexagonal winding mold (not shown). The hollow coil 100 is hexagonal in shape, matching the open shape of the hexagonal winding mold. This invention requires removing the hollow coil 100 from the hexagonal winding mold and completing the flattening process. When removing the hollow coil 100, the hexagonal winding mold can retract, facilitating the flexible removal of the hollow coil 100.

[0053] In use, the entire utility model is mounted on a mobile mechanical module (not shown in the figure). The mobile mechanical module is also provided with a flattening component that is connected to the first rubbing plate 11 and the second rubbing plate 21 respectively and is used to realize the staggered movement of the first rubbing plate 11 and the second rubbing plate 21 to flatten the wound hollow coil 100. The flattening component can be an existing structure, or it can adopt the structure of the active linkage rubbing plate 4 and the driven linkage rubbing plate 5 described below.

[0054] Under the action of the transfer mechanical module, the entire structure of this utility model approaches the hexagonal winding mold. The extended ends of the first and second rubbing plates 11 and 21 respectively grip the outer sides of the two opposite sides (first sidewall 101 and second sidewall 102) of the wound hollow coil 100. Under the action of the transfer mechanical module, the entire structure moves away from the hexagonal winding mold to remove the wound hollow coil 100. Then, the first inner pressure plate cross-shaped linear drive 13 and the second inner pressure plate cross-shaped linear drive 23 respectively drive the first inner pressure plate 12 and the second inner pressure plate 22 to extend into the wound hollow coil 100. The first inner pressure plate 12 cooperates with the extended end of the first rubbing plate 11 to clamp the inner and outer sides of the first sidewall 101, thus fixing the position of the wire harness in the first sidewall 101. The second inner pressure plate 22 cooperates with the extended end of the second rubbing plate 21 to clamp the inner and outer sides of the second sidewall 102, thus fixing the position of the wire harness in the second sidewall 102. Then, the flattening component drives the first inner pressure plate 12 and the first rubbing plate 11 to move synchronously, and the second inner pressure plate 22 and the second rubbing plate 21 to move synchronously. The first rubbing plate 11 and the second rubbing plate 21 move in a staggered manner (approaching each other while moving alternately) until the first inner pressure plate 12 and the second inner pressure plate 22 are about to touch, at which point the staggered movement stops, thus completing the main flattening process of winding the hollow coil 100 (the entire flattening process consists of a main flattening process and a supplementary flattening process). Then, under the action of the first inner pressure plate cross-linear drive 13 and the second inner pressure plate cross-linear drive 23, the first inner pressure plate 12 and the second inner pressure plate 22 are pulled out from the wound hollow coil 100 and spread outwards, providing space for the continued staggered movement of the first rubbing plate 11 and the second rubbing plate 21. The continued staggered movement of the first rubbing plate 11 and the second rubbing plate 21 completes the supplementary flattening process of winding the hollow coil 100.

[0055] Compared with the prior art, this utility model, by adding the first inner pressure plate 12 and the second inner pressure plate 22 and their driving parts, can ensure that the first sidewall 101 and the second sidewall 102 are always fixed in the whole process of the main flattening process. Moreover, the main flattening process completes most of the deformation action of the entire flattening process, that is, the main flattening process accounts for most of the entire flattening process. This can effectively prevent the wire harness position from slipping and misaligning during the flattening process of the hollow coil 100 under force, improve the stability of the flattening and forming effect, make the obtained regular wire block 200 the same as the predetermined shape, and greatly improve the yield of the regular wire block 200.

[0056] According to a specific embodiment of the present invention, the first swivel board 11 includes: a first front and rear swivel board 111 and a first outer pressure plate 112 fixedly installed at one end of the first front and rear swivel board 111; a first inner pressure plate cross linear drive 13 is installed on the upper part of the first front and rear swivel board 111; the second swivel board 21 includes: a second front and rear swivel board 211 and a second outer pressure plate 212 fixedly installed at one end of the second front and rear swivel board 211; a second inner pressure plate cross linear drive 23 is installed on the upper part of the second front and rear swivel board 211; the first inner pressure plate 12 and the first outer pressure plate 112 are respectively used to press and clamp the inner and outer sides of the first sidewall 101; the second inner pressure plate 22 and the second outer pressure plate 212 are respectively used to press and clamp the inner and outer sides of the second sidewall 102.

[0057] In this embodiment, more specifically, the first front and rear winding plates 111 are horizontal plates. The first outer pressure plate 112 is generally a slender rod, and the two are detachably connected. In specific implementations, the first outer pressure plate 112 of different regular sizes can be replaced according to the specifications and dimensions of the hollow coil 100 being wound. The horizontal plate-shaped first front and rear winding plates 111 facilitate the provision of sufficient and stable installation space for the active linkage winding disc 4 and the first inner pressure plate cross linear drive 13. The structure and function of the second winding plate 21 are described above for the first winding plate 11, and will not be repeated here.

[0058] According to a specific embodiment of the present invention, the anti-misalignment coil flattening execution module for the hollow cup motor coil flattening device further includes an active linkage rubbing disc 4 and a driven linkage rubbing disc 5 that rotates synchronously with the active linkage rubbing disc 4. The upper two sides of the active linkage rubbing disc 4 are rotatably connected to the first front and rear thread rubbing plates 111 and the second front and rear thread rubbing plates 211, respectively. The upper two sides of the driven linkage rubbing disc 5 slide against the inner sidewalls of the first front and rear thread rubbing plates 111 and the second front and rear thread rubbing plates 211, respectively.

[0059] In this embodiment, only the upper two sides of the active linkage spinning disc 4 are rotatably connected to the first and second front and rear spinning plates 111 and 211, respectively. For the driven linkage spinning disc 5, its upper two sides are configured to slide against the inner walls of the first and second front and rear spinning plates 111 and 211, respectively. With this structure, the driven linkage spinning disc 5 can both constrain the sliding direction of the first and second front and rear spinning plates 111 and 211 through the abutment structure and slide relative to them. This provides good operational flexibility and improves the smoothness of the spinning action of the first and second front and rear spinning plates 111 and 211.

[0060] According to a specific embodiment of the present invention, the first wire twisting assembly 1 and the second wire twisting assembly 2 are symmetrical to each other; the first front and rear wire twisting plate 111 is provided with a recessed first inner pressure plate receiving groove 1111 on the side near the second front and rear wire twisting plate 211, and the second front and rear wire twisting plate 211 is provided with a recessed second inner pressure plate receiving groove 2111 on the side near the first front and rear wire twisting plate 111. The anti-misalignment coil flattening execution module for the hollow cup motor coil flattening device includes a fully retracted state. When the anti-misalignment coil flattening execution module for the hollow cup motor coil flattening device is in the fully retracted state, the first inner pressure plate 12 is received in the first inner pressure plate receiving groove 1111, the second inner pressure plate 22 is received in the second inner pressure plate receiving groove 2111, and the gap between the first outer pressure plate 112 and the second outer pressure plate 212 is less than or equal to the thickness value of the regular wire block 200.

[0061] In this embodiment, before the supplementary flattening process of the wound hollow coil 100, the first inner pressure plate cross linear drive 13 drives the first inner pressure plate 12 to retract into the first inner pressure plate receiving groove 1111, and at the same time, the second inner pressure plate cross linear drive 23 drives the second inner pressure plate 22 to retract into the second inner pressure plate receiving groove 2111. This reduces the size of the device and facilitates the continued closing of the first outer pressure plate 112 and the second outer pressure plate 212 to complete the supplementary flattening process. In the fully retracted state, the gap between the first outer pressure plate 112 and the second outer pressure plate 212 ensures that the wound hollow coil 100 is completely flattened.

[0062] In this embodiment, since the first yarn twisting assembly 1 and the second yarn twisting assembly 2 are symmetrical structures, the specific structure of the second yarn twisting assembly 2 is the same as that of the first yarn twisting assembly 1.

[0063] Please refer to Figure 5 The diagram shows the first inner pressure plate 12 in the following states from top to bottom: open and retracted, open and extended, and pressing the coil sidewall.

[0064] Please refer to Figure 6The diagram shows, from top to bottom, the second inner pressure plate 22 in the following states: the state of being housed in the second inner pressure plate receiving groove 2111, and the state of being opened and extended.

[0065] According to a specific embodiment of this utility model, the first inner pressure plate cross linear drive 13 includes: a wide-direction slide rail module 131, a wide-direction connecting plate 132, a wide-direction telescopic power 133, a long-direction slide rail module 134, a long-direction connecting plate 135, and a long-direction telescopic power 136; the wide-direction slide rail module 131 includes: a wide-direction guide rail 1311 and a wide-direction guide groove 1312 that cooperates with the wide-direction guide rail 1311. The wide-direction guide rail 1311 and the wide-direction telescopic power 133 are respectively fixed on the upper part of the first front and rear thread-rolling plates 111 along the width direction of the first thread-rolling plate 11, and the wide-direction guide rail 1311 and the wide-direction telescopic power 133 are arranged side by side. One side of the wide-direction connecting plate 132 is fixedly fastened to the wide-direction guide groove 1312, and the other side of the wide-direction connecting plate 132 faces the wide-direction telescopic power 133. The configuration includes a wide-direction telescopic power 133 connected to a wide-direction connecting plate 132, which drives the wide-direction connecting plate 132 to slide along the wide-direction guide rail 1311; a long-direction connecting plate 135 fixed on the side of the wide-direction connecting plate 132 away from the wide-direction telescopic power 133; a long-direction slide rail module 134 including a long-direction guide rail 1341 and a long-direction guide groove 1342 that cooperates with the long-direction guide rail 1341; a long-direction telescopic power 136 and a long-direction guide groove 1342 fixed on the long-direction connecting plate 135 along the length direction of the first corrugated board 11; the long-direction telescopic power 136 and the long-direction guide groove 1342 being arranged vertically; and a long-direction telescopic power 136 connected to a first inner pressure plate 12, which drives the long-direction guide rail 1341 and the first inner pressure plate 12 to slide together along the long-direction guide groove 1342.

[0066] In this embodiment, a structure for the first inner pressure plate cross-shaped linear drive 13 is specifically designed. The operating mechanism of the first inner pressure plate cross-shaped linear drive 13 is as follows: the wide-direction telescopic power 133 extends and retracts, driving the wide-direction connecting plate 132, together with the upper long-direction slide rail module 134, the long-direction connecting plate 135, the long-direction telescopic power 136, and the first inner pressure plate 12, to extend and retract along the wide-direction guide rail 1311; the long-direction telescopic power 136 extends and retracts, driving the long-direction connecting plate 135, the long-direction guide rail 1341, and the first inner pressure plate 12 to slide along the long-direction guide groove 1342; ultimately achieving the position adjustment requirement of the first inner pressure plate 12. The structure of the second inner pressure plate cross-shaped linear drive 23 is the same as that of the first inner pressure plate cross-shaped linear drive 13. The wide-direction slide rail module 131 and the long-direction slide rail module 134 can be existing ready-made products that can be directly purchased externally. In specific implementation, the specific stroke specifications are selected according to the needs.

[0067] According to a specific embodiment of the present invention, the wide connecting plate 132 includes a first connecting part 1321 and a second connecting part 1322 that are fixedly connected and together form an "L" shape. The first connecting part 1321 is a rectangular plate with an opening at the bottom, and the second connecting part 1322 is a square column. The first connecting part 1321 is fixedly fastened to the wide guide groove 1312, and the second connecting part 1322 is disposed directly opposite the wide telescopic power 133, which is connected to the second connecting part 1322.

[0068] More specifically, the wide-direction telescopic power 133 and the long-direction telescopic power 136 are pneumatic cylinders, hydraulic cylinders, or electric telescopic cylinders.

[0069] In this embodiment, the structure of the first connecting part 1321 facilitates a stable connection between the wide connecting plate 132 and the wide guide groove 1312. Furthermore, the "L"-shaped wide connecting plate 132 provides sufficient space for the installation and extension / retraction of the wide telescopic power 133, thus improving the compactness of the device.

[0070] According to a specific embodiment of the present invention, the opening and closing drive assembly 3 includes: an opening telescopic cylinder 31, a closing tension spring 32, a cylinder mounting base 33, and a cylinder rod push plate 34. The cylinder mounting base 33 is fixed to the lower part of the first front and rear thread rolling plate 111, and the cylinder rod push plate 34 is fixed to the lower part of the second front and rear thread rolling plate 211. The two ends of the closing tension spring 32 are respectively connected to the cylinder mounting base 33 and the cylinder rod push plate 34. One end of the opening telescopic cylinder 31 is installed on the cylinder mounting base 33, and the other end of the opening telescopic cylinder 31 abuts against the cylinder rod push plate 34.

[0071] More specifically, the telescopic cylinder 31 is a hydraulic, pneumatic, or electric telescopic cylinder, and the telescopic cylinder 31 includes: a cylinder mounted on the cylinder mounting seat 33 and a cylinder rod abutting against the cylinder rod push plate 34.

[0072] More specifically, the closed tension spring 32 is a tension spring.

[0073] In use, opening the telescopic cylinder 31 introduces extension power (if it is a cylinder, pressurized gas is filled into the intake chamber), causing the cylinder rod of the telescopic cylinder to extend and drive the first washboard 11 and the second washboard 21 to open, and stretching the closing tension spring 32 to accumulate elastic force. In this state, the first outer pressure plate 112 and the second outer pressure plate 212 are open and located on the outside of the first side wall 101 and the second side wall 102, respectively. When opening the telescopic cylinder 31 loses extension power, the first washboard 11 and the second washboard 21 close under the action of the closing tension spring 32. In this state, the first outer pressure plate 112 and the second outer pressure plate 212 respectively hold the outside of the first side wall 101 and the second side wall 102, for removing the hollow coil 100 from the hexagonal winding die.

[0074] Please refer to this carefully. Figure 7-8According to a specific embodiment of the present invention, the hollow coil 100 further includes multiple wire ends distributed in a straight line; the anti-misalignment coil flattening execution module for the hollow cup motor coil flattening device further includes a wire clamping assembly 6 for simultaneously clamping and fixing all wire ends.

[0075] According to a specific embodiment of this utility model, the wire clamping head assembly 6 includes: a cylinder fixing plate 61, a two-finger opening and closing gripper 62 fixed to the side of the cylinder fixing plate 61, and a first wire clamping head plate 63 and a second wire clamping head plate 64 respectively connected to and driven to open and close by the two-finger opening and closing gripper 62; the anti-misalignment coil flattening execution module for the hollow cup motor coil flattening device also includes a coil positioning state. When the anti-misalignment coil flattening execution module for the hollow cup motor coil flattening device is in the coil positioning state, the first wire clamping head plate 63 and the second wire clamping head plate 64 jointly clamp and fix all wire ends; the first inner pressure plate 12 and the first outer pressure plate 112 respectively clamp the inner and outer sides of the first side wall 101; the second inner pressure plate 22 and the second outer pressure plate 212 respectively clamp the inner and outer sides of the second side wall 102.

[0076] In this embodiment, the cylinder fixing plate 61 is used to fix the two-finger opening and closing gripper 62. The two-finger opening and closing gripper 62 has two telescopic gripping fingers, which are respectively connected to the first wire clamping head plate 63 and the second wire clamping head plate 64.

[0077] In this embodiment, in addition to fixing the first sidewall 101 and the second sidewall 102 in the main flattening process, a wire clamping assembly 6 is added, which can be opened and closed freely. By using the wire clamping assembly 6 to clamp and fix all wire ends in the entire flattening process, it is possible to effectively prevent the wire ends from slipping or misaligning during the flattening process of the hollow coil 100 under force, thereby further improving the stability of the flattening and forming effect.

[0078] According to a specific embodiment of the present invention, the cylinder fixing plate 61 is generally in the shape of a door frame, and the lower part of the cylinder fixing plate 61 is respectively located above the first front and rear thread rolling plate 111 and the second front and rear thread rolling plate 211. Universal balls 65 are respectively provided on the lower parts of both sides of the cylinder fixing plate 61, and the upper parts of the first front and rear thread rolling plate 111 and the second front and rear thread rolling plate 211 are in contact with the lower part of the cylinder fixing plate 61 through the universal balls 65.

[0079] With the structure of this embodiment, when the cylinder fixing plate 61 is fixed, the cylinder fixing plate 61 can achieve an upper limit on the first front and rear thread-pulling plates 111 and the second front and rear thread-pulling plates 211, that is, restrict the upward movement of the first front and rear thread-pulling plates 111 and the second front and rear thread-pulling plates 211 without affecting the degree of freedom of the first front and rear thread-pulling plates 111 and the second front and rear thread-pulling plates 211 in the horizontal direction. Furthermore, the use of the universal ball 65 can further improve the smoothness of the sliding of the first front and rear thread-pulling plates 111 and the second front and rear thread-pulling plates 211.

[0080] According to a specific embodiment of this utility model, one end of the first wire clamping head plate 63 and the second wire clamping head plate 64, facing the same direction, is fixed to the two-finger opening and closing claw 62. The other end of the first wire clamping head plate 63 is provided with a first adjustment window 631 passing through it, so that a first upper clamping strip 632 and a first lower clamping strip 633 are formed on the upper and lower sides of the width direction of the first adjustment window 631, respectively. The second wire clamping head plate 64 is provided with a second adjustment window 641 passing through it, so that a second upper clamping strip 642 and a second lower clamping strip 643 are formed on the upper and lower sides of the width direction of the second adjustment window 641. The first adjustment window 631 is directly opposite the second adjustment window 641, and the two are shaped like... The shapes are the same; a complete sheet-like holding area 66 is formed on each of the left and right sides of the first adjustment window 631; among the multiple wire ends in the hollow coil 100, the two wire ends located on both sides are set as half-strand wire ends to be twisted 103, and the wire end between the two half-strand wire ends to be twisted 103 is set as full-strand wire end 104; when the anti-misalignment coil flattening execution module of the hollow cup motor coil flattening device is in the coil positioning state: all full-strand wire ends 104 are clamped and fixed by the first upper clamping bar 632, the first lower clamping bar 633, the second upper clamping bar 642 and the second lower clamping bar 643; the two half-strand wire ends to be twisted 103 are respectively located in the two complete sheet-like holding areas 66.

[0081] The full-strand wire head 104 is a complete electrode wire head. The diameter of the two half-strand wire heads 103 to be twisted together is generally half the diameter of the full-strand wire head 104. In subsequent processes, the two half-strand wire heads 103 to be twisted together need to be twisted together into a single full-strand wire head 104.

[0082] The first clamping plate 63 and the second clamping plate 64 need to clamp two wire ends of different diameters simultaneously. To ensure stable clamping, in this embodiment, a first adjustment window 631 and a second adjustment window 641 are provided. The full-strand wire end 104 is clamped only at its upper and lower ends by the first upper clamping bar 632 and the first lower clamping bar 633, while the entire lower section of the half-strand wire end 103 to be twisted is clamped. This allows the full-strand wire end 104 to be easily flattened first, so that the thickness of the flattened full-strand wire end 104 is comparable to the diameter of the half-strand wire end 103 to be twisted. Then, the first clamping plate 63 and the second clamping plate 64 simultaneously clamp wire ends of similar thickness, ensuring that the half-strand wire end 103 to be twisted is also stably clamped. This ensures that each wire end is stably clamped during the flattening process, further improving the accuracy of coil flattening.

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.
