Technical Field

[0001] The invention relates to the field of winding machines, and in particular to a heating structure of a winding machine. Background Art

[0002] A winding machine is a device that winds a linear object onto a specific workpiece. The above-mentioned linear objects are mostly enameled copper wires, enameled aluminum wires, etc., which can be used to wind the inductor coils of electronic products. However, with the increasing number of types and models of electronic technology products, the requirements for winding machines are also getting higher and higher.

[0003] For example, a traditional winding machine can only wind coils in one direction on one side of a PCB at a time. For products where coils are wound on both sides of the PCB and the coils on both sides have the same rotation direction with their respective sides as a reference, there are shortcomings such as low processing efficiency, difficulty in controlling the processing standards of double-sided coils, low qualified rate of processed products, and high processing costs. If the winding is done manually, it is easy to have undesirable conditions such as uneven tightness and crossing, and the efficiency is lower and the cost is higher.

[0004] At present, there is no winding machine that can simultaneously wind coils with the same rotation direction on both sides of a substrate (such as a PCB board).

[0005] In addition, the coil obtained by winding needs to be heated and cooled so that the hot melt adhesive on the enameled wire can shape the coil obtained by winding. When heating, the hot melt adhesive is melted by blowing hot air from the outside, which not only often leads to the undesirable phenomena of the hot melt adhesive being scorched, the insulating paint being damaged, and the coil being baked black, but also the heating device used has high purchase cost, complex structure, high energy consumption, and is extremely inconvenient to use. Therefore, it is necessary to improve the above-mentioned shortcomings. Summary of the invention

[0006] In order to improve the above shortcomings, the present invention provides a heating structure of a winding machine capable of in-situ heating of a coil. The present invention is implemented through the following technical scheme: a heating structure of a winding machine, comprising a frame and a main control device, the frame is provided with a winding mechanism and a heating device, the winding mechanism is connected to the main control device, the rotating shaft of the winding mechanism is used to correspond to the workpiece to be wound, and the rotating shaft is provided with a gas path corresponding to the workpiece and connected to the heating device.

[0007] Preferably, a first air inlet and an air outlet are provided on the air path, the air outlet is located on the rotating shaft corresponding to the workpiece, and the first air inlet is located at a heating position corresponding to the heating device.

[0008] Preferably, the air path is further provided with a second air inlet hole, and the second air inlet hole is located between the air outlet hole and the heating part of the heating device.

[0009] Preferably, the heating device includes a heater, the air path passes through the heater, the heater includes an air duct, a heating wire rod and a cover, the heating wire rod is installed in the air duct, the cover is installed at the outer port of the air duct, and the first air inlet is located on the air duct corresponding to the heating wire rod.

[0010] Preferably, the workpiece is a substrate, and the air outlet comprises a first air outlet and a second air outlet, and the first and second air outlets are respectively located on two sides of the substrate.

[0013] Preferably, when viewed from the second rotating shaft member toward the first rotating shaft member, the first and second rotating shaft members have the same rotation direction, and the rotation speed of the first rotating shaft member is twice that of the second rotating shaft member.

[0014] The present invention has a simple structure, practical functions, and lower energy consumption. The wound coil can be heated in situ, which makes the heating temperature easier to control, the shaping process is simpler and easier, and the efficiency is higher.

A threading hole 330 is provided at the outer end surface of the first rotating shaft 33, and a wire outlet communicating with the threading hole 330 is provided at the middle portion of the first rotating shaft 33 corresponding to the conduit 321. Figure 3 The wire path 210 shown in the figure, that is, one side of the substrate 1 is before winding, and the enameled wire is passed through the threading hole 330, the first rotating shaft 33, the wire outlet, the conduit 321 and the guide needle 322. The first photoelectric sensor 34 includes a trigger plate 341 and a photoelectric sensor 342. The trigger plate 341 is fixed on the first output gear, and the photoelectric sensor 342 is fixed on the vertical plate. The trigger plate 341 and the photoelectric sensor 342 cooperate with each other to generate a signal for monitoring the rotation speed of the first rotating shaft 33. The main control device can control the first motor 31 based on the signal of the photoelectric sensor 342 to realize the monitoring and regulation of the rotation speed of the first rotating shaft 33.

[0032] When the first rotating shaft member 33 is implemented specifically, it preferably includes a first half shaft 331 and a second half shaft 332. The wire path 210 passes through the first half shaft 331. A bearing is provided at the connection between the first half shaft 331 and the second half shaft 332. When winding, the first half shaft 331 rotates, and the second half shaft 332 can dynamically adapt to the actual winding environment, and can achieve no rotation or low rotation speed. This can provide protection for the substrate 1 and the coil, avoid unnecessary friction interference, and also facilitate the winding formation of the coil.

[0033] Continue to refer to Figures 1 to 6As shown, a mounting seat 40 is further provided on the frame, and a second winding mechanism is installed on the mounting seat 40. Specifically, the second winding mechanism includes a second motor 41, a second input gear, a second synchronous belt, a second output gear, a second photoelectric sensor 43 and a second rotating shaft. The second motor 41 drives the second rotating shaft to rotate through the second input gear, the second synchronous belt and the second output gear. The second rotating shaft includes a rotating shaft sleeve 42 and a hollow shaft 73. The rotating shaft sleeve 42 is sleeved on the hollow shaft 73, and a clamping strip and a clamping strip groove are provided between the two. This structure can make the hollow shaft 73 3 rotates with the rotating shaft sleeve 42 and can move along the axial direction of the rotating shaft sleeve 42. The rotating shaft sleeve 42 is rotatably arranged on the vertical wall of the mounting seat 40 through a bearing. The inner end of the hollow shaft 73 passes through the rotating shaft sleeve 42. The outer peripheral surface of the inner end is provided with a mounting structure 732. The mounting structure 732 is used to install and fix the substrate 1. The second photoelectric sensor 43 has the same function as the first photoelectric sensor 34.

[0034] When in use, the substrate 1 is arranged between the first rotating shaft and the second rotating shaft, the first winding mechanism winds the wire on one side of the substrate 1, and the second winding mechanism winds the wire on the other side of the substrate 1. Figure 7 As shown, before winding, the enameled wire 2 is passed through the substrate 1, and then the substrate 1 is installed at the mounting structure 732 so that it can rotate with the second rotating shaft, and then the enameled wire 2 on one side of the substrate 1 is passed through the wire path 210, and the enameled wire 2 on the other side of the substrate 1 is released by a wire release device or manual operation control, and then the first and second winding mechanisms are started simultaneously by the main control device, so that coils can be wound on both sides of the substrate 1 at the same time. The above-mentioned wire release device is preferably implemented in the form of a mechanical arm. Specifically, the mechanical arm is connected to the main control device so that it cooperates with the winding mechanism to release the wire.

[0035] For example, refer to Figure 8 and 9 As shown, the winding machine of this embodiment starts the first and second winding mechanisms simultaneously through the main control device, and observes from the second rotating shaft member to the first rotating shaft member as a reference, so that the second rotating shaft member and the first rotating shaft member are both rotated clockwise, and the rotation speed of the first rotating shaft member is controlled to be twice that of the second rotating shaft member. In this way, the first coil 21 and the second coil 22 with the same rotation direction and number of turns can be wound on both sides of the substrate 1 at the same time, that is, the first coil 21 and the second coil 22 have the same number of turns and are both counterclockwise. Of course, before the operation, it should be ensured that the enameled wire 2 on both sides of the substrate 1 has sufficient length or is equal in length. After the winding is completed, a PIN needle is set on the substrate 1 to fix the wire head.

[0036] In specific implementation, it is preferred that the frame is further provided with a slide mechanism connected to the main control device, specifically, as Figures 1 to 3 As shown, the slide mechanism includes a first cylinder 51, a slide and a guide rail.

The mounting seat 40 is installed on the slide, and the guide rail is installed on the base plate 30. In this way, the main control device can control the first cylinder 51 to achieve adjustment and control of the distance between the first and second rotating shaft members, so that the substrate 1 can be installed and disassembled more conveniently, thereby improving work efficiency.

[0037] In order to facilitate the heating and cooling of the winding coil to shape it, in the specific implementation, it is preferred that a heating device is also provided on the frame. Specifically, the heating device of this embodiment is also referred to Figures 10 to 12 As shown, it includes a heater 71, a hollow shaft 73 is provided with an air outlet at a position corresponding to the substrate 1, an air path connecting the air outlet and the heater 71 is penetrated inside the hollow shaft 73, the heater includes an air duct 714, an electric heating wire rod 712 and a cover 711, the electric heating wire rod 712 is installed in the air duct 714, the cover 711 is installed at the outer end of the air duct 714, a first air inlet 7141 is provided on the air duct 714 at a position corresponding to the electric heating wire rod 712, and a second air inlet 7142 is provided on the air path between the air outlet and the heater 71 (further specifically the electric heating wire rod 712). When heating is required, air is introduced through the first air inlet 7141, and the introduced air heats the substrate 1 at the air outlet after the electric heating wire rod 712 is heated. When cooling is required, the connection between the electric heating wire rod 712 and the power supply is disconnected, and cooling air at room temperature or low temperature is introduced through the second air inlet 7142, and the cooling air cools the substrate 1 at the air outlet.

[0038] The air outlet of this embodiment preferably includes a through hole 731 and a through opening 733. A first air cavity connecting the through opening 733 and the outside is provided at the second semi-shaft 332 corresponding to the through opening 733. A second air cavity connecting the through hole 731 and the outside is provided at the rotating shaft sleeve 42 corresponding to the through hole 731. The through opening 733 and the first air cavity, and the through hole 731 and the second air cavity are respectively located on both sides of the substrate 1, so as to respectively correspond to the first coil 21 and the second coil 22 formed by winding on both sides of the substrate 1. The setting of the first and second air cavities is conducive to faster heating and cooling at this location, thereby improving the heating and cooling efficiency of the coils, saving operation time, and reducing energy costs.

[0039] The heater 71 can be arranged on the mounting seat 40 during specific implementation. The heater 71 of this embodiment is fixedly arranged on the frame through the fixing seat 713. The heater 71 and the hollow shaft 73 are connected through the adapter shaft cylinder 72. Specifically, the outer end of the hollow shaft 73 is rotatably arranged on the slide 60 through the bearing and moves with the slide 60. The slide 60 and the mounting seat 40 are slidably connected. The mounting seat 40 is fixedly provided with a second cylinder 61 connected to the main control device. The telescopic part of the second cylinder 61 is connected to the slide 60. The adapter shaft One end of the cylinder 72 is fixedly connected to the sliding seat 60, and the other end of the adapter shaft cylinder 72 is slidably connected to the air duct 714 to realize the connection of the air path. When in use, the main control device can slide through the second cylinder 61, thereby driving the hollow shaft 73 and the adapter shaft cylinder 72 to move along the axial direction relative to the rotating shaft sleeve 42, that is, adjusting the axial position of the adapter shaft cylinder 72 and the hollow shaft 73. This structure is conducive to the setting of the heater 71, and can better connect and cooperate between the heating device and the winding mechanism, making the winding operation more convenient and easy, and the degree of automation is higher.
