Description

Technical Field

[0001] The present patent application relates to manufacturing equipment for wire core electronic devices, and more particularly to manufacturing equipment for manufacturing induction devices by flat non-contact winding of fine metal wires, and more specifically to manufacturing equipment for preparing the inner core of an induction device using a temperature-sensitive platinum thermal resistance wire as the core. Background Art

[0002] The existing platinum thermistor temperature sensor has a sensing core composed of a platinum thermistor wire spirally wound on a core body. The minimum diameter of the core body itself is Φ0.7mm, so it is difficult to produce and develop thin sensing core products, which affects the temperature sensing performance of the temperature sensor, such as sensing sensitivity, sensing accuracy and anti-interference. Therefore, ultra-thin platinum resistor sensing cores are imperative.

[0003] Patent document CN210198591 U discloses a new type of ultra-thin platinum thermal sensor. The solution is to coil a platinum thermal resistance wire between two insulating protective sheets. Figure 1 As shown. The diameter of the platinum thermal resistor wire is only 0.03mm, and the thickness of the entire sensing core can be as thin as 0.2mm. The ultra-thin temperature sensor can greatly improve its sensing sensitivity, temperature sensing accuracy and anti-interference performance, especially becoming a new type of ultra-thin thermal sensor with compact layout and high-precision motor thermal sensing response protection. However, this ultra-thin platinum thermal sensor sensing core has higher process manufacturing requirements, because the diameter of the platinum thermal resistor wire is only 0.03mm, and the spacing between the winding wires is only 0.2-0.5mm. During the winding, it is necessary to ensure that the platinum wire does not deviate or short-circuit. Therefore, the difficulty of its manufacturing process can be imagined, resulting in low production efficiency, difficult quality assurance, and inability to implement large-scale industrial production of such ultra-thin platinum thermal sensor sensing cores. Summary of the invention

[0004] The invention purpose of this patent application is to provide a new type of ultra-thin platinum thermal sensor, especially its inductive core, with an ultra-thin platinum thermal sensor inductive core manufacturing device suitable for large-scale industrial application.

[0009] One of the preferred means of the above overall technical solution is that the XY axis linear coordinate drive system is an XY axis ball screw linear drive module.

[0010] One of the preferred means of the above-mentioned overall technical solution is that the platinum wire supply group includes a platinum wire material tray and a platinum wire guide arranged on the vertical rotating shaft part. The platinum wire guide is a guide groove, a guide tube or a guide hole, which is in the same plane perpendicular to the wire roller as the axial center line of the wire roller.

[0011] The technical solution of the ultra-thin platinum thermal sensor induction core manufacturing equipment disclosed in this patent application is that the XY axis linear coordinate drive system drives the roller wire working head to accurately position and move the coordinates, and accurately controls the steering motor to manipulate the roller wire working head to turn. In combination with a wire roller with an outer diameter of 0.5-0.8mm, the platinum thermal resistance wire with a wire diameter of only 0.03mm is accurately coiled and laid on the rubber surface of the insulating protective sheet on one side, ensuring the accuracy and quality of the platinum thermal resistance wire winding, greatly improving the manufacturing efficiency of the ultra-thin platinum thermal sensor induction core, reducing the manufacturing cost, and meeting the technical requirements of large-scale industrial production.

[0017] The ultra-thin platinum thermal sensor induction core making equipment applied for in this patent is a special equipment for preparing ultra-thin platinum thermal sensor platinum thermal induction core by plane winding of platinum thermal resistance wire. Figure 2 , Figure 3As shown, its overall composition includes two major components: a roller wire operation head 2 and an XY axis linear coordinate driving system 1 that drives the roller wire operation head 2 to position and move the cross coordinates.

[0018] The XY axis linear coordinate drive system 1 may use an XY axis ball screw linear drive module.

[0019] The wire roller operation head 2 comprises a vertical rotating shaft, a wire roller and a platinum wire supply group. The vertical rotating shaft is composed of a vertical rotating shaft 3 and a steering motor for driving the vertical rotating shaft 3. The wire roller is rotatably arranged at the top of the vertical rotating shaft 3.

[0020] Under the control of an external intelligent controller, the XY-axis ball screw linear drive module and the steering motor use the polyimide substrate rubber surface 20 as the coordinate plane to accurately position and steer the mobile roller wire operation head 2. The platinum thermal resistance wire 10 with a wire diameter of only 0.03 mm is flatly coiled and rolled and fixed on the polyimide substrate rubber surface 20 by the wire roller, and finally bonded to the other side of the polyimide substrate to complete the manufacture of the ultra-thin platinum thermal sensor sensing core.

[0021] The best outer diameter of the roller shaft of the silk roller is 0.5-0.8 mm, and the length of the silk roller is preferably 1-4 mm, preferably 1-2 mm. Figure 6 , Figure 7 As shown, the wire roller is composed of a stainless steel core shaft 4 which is freely rotatable and sleeved on a stainless steel sleeve 5 with an outer diameter of 0.5-0.8 mm.

[0022] The platinum wire supply group includes a platinum wire material tray 7 and a platinum wire guide disposed on the wire roller operation head 2. The platinum thermal resistance wire 10 is fed into the wire roller from the platinum wire material tray 7 through the guidance of the platinum wire guide and is wound and rolled to be fixed on the rubber surface 20 of the polyimide substrate. Figure 4 , Figure 5 In the implementation structure, the platinum wire guide is a fixed pulley 8, whose central guide ring groove 18 and the center line of the stainless steel sleeve 5, that is, the axial center line of the stainless steel sleeve 5, are on the same plane perpendicular to the wire roller, and the platinum thermal resistance wire 10 is directed to the center of the stainless steel sleeve 5. In order to ensure that the platinum thermal resistance wire 10 is accurately coiled according to the designed coiling structure, the platinum thermal resistance wire 10 of the platinum wire material plate 7 enters the wire roller from the fixed pulley 8 close to the wire roller side, such as Figure 3 shown.

[0023] Practice has proved that the best setting of the wire roller diameter is 0.5-0.8mm. Under the control of the external intelligent controller, the wire roller can accurately roll and fix the platinum thermal resistance wire 10 on the rubber surface 20 of the polyimide sheet according to the set winding route as the wire roller operation head 2 moves, thereby ensuring that the platinum thermal resistance wire 10 is accurately fixed on the rubber surface 20 of the polyimide sheet according to the designed winding structure, thereby ensuring the quality of the sensing core of the ultra-thin platinum thermal sensor.

[0024] The platinum wire guide can also be a guide groove, a guide tube, or a guide hole, which is arranged on the front side of the wire roller and is in the same plane perpendicular to the wire roller as the axial midline of the wire roller.
