[0002] PTC heating film is a thin-film heating element that uses the PTC effect to achieve heating function. The characteristic of PTC heating film is that when its temperature rises to a certain value, the resistance will increase sharply, thereby automatically limiting the increase of current. This makes the PTC heating film have the characteristics of self-limiting temperature, improving safety and reliability. PTC heating film is mainly composed of PTC heating element, electrode material, insulation layer, protective layer, backing material layer and adhesive layer. PTC heating film is widely used in heating elements in home appliances, automobiles, medical care, aerospace and other fields.

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0025] like Figure 1-Figure 5As shown, a PTC heating film positioning and pasting device includes: a pasting workbench 1, a placement plate 101 arranged on one side of the top of the pasting workbench 1, a support frame 102 installed on the top of the placement plate 101, a glue drop component arranged on the top of the placement plate 101, the glue drop component includes: a liquid storage tank 103, a liquid pump 104, a liquid suction pipe 105, a delivery pipe 106 and a glue drop head 107, a pasting component arranged on one side of the bottom of the support frame 102, the pasting component includes: a pressure plate 2, a vacuum suction cup 201, an infrared sensor 202, a telescopic cylinder 203, a telescopic rod 204 and a shielding plate 3.

[0026] Among them, a liquid storage tank 103 is fixedly installed on the top side of the support frame 102, and a liquid pump 104 is fixedly installed on the bottom side of the support frame 102 by bolts. A liquid extraction pipe 105 is fixedly installed between the water inlet end of the liquid pump 104 and the liquid storage tank 103, and a delivery pipe 106 is fixedly connected to the water outlet end of the bottom of the liquid pump 104, and a glue dripping head 107 is threadedly installed on the bottom side of the delivery pipe 106.

[0027] When pasting the PTC heating film, the backing material layer of the PTC heating film is placed on the placement plate 101, so that the side of the backing material layer is opposite to the glue dropper 107, and the liquid pump 104 is started. The liquid pump 104 generates negative pressure suction inside the liquid extraction tube 105, and the liquid extraction tube 105 extracts the glue inside the liquid storage tank 103 and discharges it to the delivery pipe 106 through the liquid pump 104. The delivery pipe 106 delivers the glue to the glue dropper 107, and the glue is discharged through the glue dropper 107 and drips on the side of the backing material layer, ensuring that the amount of glue is evenly discharged, solving the problem of excessive or insufficient extrusion during the manual glue dripping process, and eliminating the need to squeeze the glue multiple times, thereby improving the glue dripping work efficiency.

[0028] Among them, the top of the placement board 101 is connected with an anti-slip pad 117 by glue. The anti-slip pad 117 is a silicone pad made of silicone material. When the base material layer is placed on the placement board 101, the base material layer and the anti-slip pad 117 are in contact with each other. Since the anti-slip pad 117 is made of silicone material, the surface of the anti-slip pad 117 has a slight roughness, which can increase the friction between the base material layer and the base material layer, thereby providing good anti-slip performance and preventing the base material layer from slipping off the placement board 101.

[0029] Among them, a first chassis 108 is provided at the bottom of the placement plate 101, and a uniform speed motor 109 is fixedly installed inside the first chassis 108. The output end of the top of the uniform speed motor 109 is driven and connected to the rotating shaft 110. A rotating hole is opened on the top of the first chassis 108, and the rotating shaft 110 passes through the rotating hole and is connected to the placement plate 101. When the glue dripping on one side of the lining material layer is completed, since the lining material layer has four sides, the uniform speed motor 109 is started to drive the rotating shaft 110 to rotate at a uniform speed inside the rotating hole, that is, the rotating shaft 110 drives the placement plate 101 and the lining material layer placed on the top to rotate at a uniform speed. After the lining material layer is rotated and adjusted, the glue dripping work can be completed on the other three sides of the lining material layer to ensure that the pasting area of ​​the lining material layer is dripped with glue.

[0030] Among them, a second chassis 111 is provided at the bottom of the first chassis 108, and the bottom end of the second chassis 111 is fixedly installed on the workbench 1 by bolts. A forward and reverse motor 112 is fixedly installed on one side of the inside of the second chassis 111, and the output end of the forward and reverse motor 112 is driven and connected to a threaded screw 113. The other end of the threaded screw 113 is rotatably connected to the inner wall of the second chassis 111 through a bearing. A support rod 114 is fixedly installed at the bottom of the first chassis 108, and a screw hole 115 is provided at the bottom of the support rod 114 for transmission connection with the threaded screw 113. A movable groove 116 for moving the support rod 114 is provided at the top of the second chassis 111.

[0031] When dripping glue on the side of the backing material layer, start the forward and reverse motor 112 to drive the threaded screw 113 to rotate forward, and the threaded screw 113 and the screw hole 115 rotate in a threaded manner, driving the support rod 114, the first chassis 108, the placement plate 101 and the backing material layer placed on the top to move to the right. When the glue dripping head 107 drips glue, the glue can be evenly dripped at different positions on the side of the backing material layer to avoid the glue gathering in one place, ensuring that the glue dripped on the side of the backing material layer is in a straight line.

[0032] The threaded screw 113 can drive the support rod 114, the first chassis 108, the placement plate 101 and the base material layer placed on the top to move left and right and adjust the position. It can be adjusted and used according to the needs of the glue dripping process to facilitate evenly dripping glue on the four sides of the base material layer.

[0033] Among them, a pressure plate 2 is provided on one side of the bottom of the support frame 102, and vacuum suction cups 201 are fixedly installed on both sides of the bottom of the pressure plate 2. An infrared sensor 202 is fixedly installed on one side of the outer end of the pressure plate 2 by bolts, and a telescopic cylinder 203 is fixedly installed on one side of the top of the support frame 102 by bolts. The output end of the telescopic cylinder 203 is connected to a telescopic rod 204, and a through hole is opened on the top of the support frame 102. The telescopic rod 204 passes through the through hole and is connected to the pressure plate 2, and a baffle plate 3 is fixedly installed on one side of the outer end of the placement plate 101 by bolts.

[0034] After evenly dripping glue on the four sides of the backing material layer, the protective layer of the PTC heating film is placed on the bottom of the vacuum suction cup 201, and the protective layer is firmly sucked and placed by the vacuum suction cup 201. At this time, the forward and reverse motor 112 is started to drive the threaded screw 113 to rotate forward, and the threaded screw 113 and the screw hole 115 are threadedly rotated, driving the support rod 114, the first chassis 108, the placement plate 101 and the backing material layer placed on the top to move to the right, so that the placement plate 101 moves to the bottom of the pressing plate 2. When the shielding plate 3 is aligned with the infrared sensor 202 at the outer end of the pressing plate 2, the infrared rays emitted by the infrared sensor 202 will be blocked by the shielding plate 3, reflecting The amount of radiation coming back will change, thereby triggering induction, that is, the infrared sensor 202 sends an electrical signal to the control panel and processes the information. The control panel will turn off the forward and reverse motors 112 and start the telescopic cylinder 203. The telescopic cylinder 203 drives the telescopic rod 204 to move downward. The telescopic rod 204 pushes the pressing plate 2, the vacuum suction cup 201 and the protective layer to move downward and contact the bottom lining material layer, so that the protective layer and the bottom lining material layer are positioned and pasted together. When the pressing plate 2 is pressed, the protective layer and the bottom lining material layer can be pressed and pasted together, without the need for multiple rework and pasting, to avoid glue overflowing from the bottom lining material layer and the outside of the protective layer to cause waste.

[0035] Among them, the infrared sensor 202 is HC-SR501, and its working principle is: the infrared sensor is a device that uses infrared technology for detection. It uses the characteristics of infrared signals to detect and identify heat sources, converts the infrared rays radiated by objects into corresponding electrical signal outputs, and analyzes and processes the objects. The infrared sensor uses an infrared sensor as a receiving element. Under the illumination of the infrared indicator light, when people or objects pass by, the objects will naturally radiate infrared rays. The infrared sensor senses the visible light within a certain range radiated by the object, and analyzes the detected object information through circuit processing and feedback system. The infrared sensor 202 is a mature conventional technology in this technical field, and this solution does not make any improvements to the circuit or program of the infrared sensor 202. The circuit and signal connection method between the infrared sensor 202 and the control panel also belongs to public conventional technology, so its circuit and signal connection relationship will not be repeated.

[0036] Among them, a vacuum pump 205 is fixedly installed on one side of the top of the pressure plate 2 by bolts, and an exhaust pipe 206 is fixed between the exhaust end of the vacuum pump 205 and the vacuum suction cup 201, and an exhaust pipe 207 is fixed on the exhaust end of the top of the vacuum pump 205. When the vacuum suction cup 201 is in use, the vacuum pump 205 is started to work, and the vacuum pump 205 generates negative pressure suction in the exhaust pipe 206 to extract the air inside the vacuum suction cup 201 and discharge it from the exhaust pipe 207, so that the inside of the vacuum suction cup 201 reaches a vacuum, and the protective layer is sucked and placed tightly to prevent the protective layer from falling off, so as to facilitate the alignment and pasting of the protective layer and the base material layer.

[0037] Among them, an exhaust pipe 208 is fixed on one side of the outer end of the vacuum suction cup 201, and a solenoid valve 209 is fixed on the exhaust pipe 208. After the protective layer and the backing material layer are pasted and fixed, the solenoid valve 209 is started to open, so that the air pressure inside the vacuum suction cup 201 is balanced with the outside, and the vacuum suction cup 201 falls off naturally, that is, the vacuum suction cup 201 does not suck the protective layer tightly, and the fixation of the protective layer is released.

[0038] Among them, the outer end of the pasting workbench 1 is fixed with a control panel by bolts, a plurality of control buttons are movably installed on the outside of the control panel, and a power cord is fixedly installed on the back of the control panel, and the liquid pump 104, the uniform speed motor 109, the forward and reverse motor 112, the infrared sensor 202, the telescopic cylinder 203, the vacuum pump 205 and the electromagnetic valve 209 are connected to the control panel through wires, and the power cord is three meters long. A plug is fixedly installed at the other end of the power cord, and the plug can be inserted into the socket to turn on the power, so that the control panel, the liquid pump 104, the uniform speed motor 109, the forward and reverse motor 112, the infrared sensor 202, the telescopic cylinder 203, the vacuum pump 205 and the electromagnetic valve 209 are connected to the control panel through wires. The machine 109, the forward and reverse motor 112, the infrared sensor 202, the telescopic cylinder 203, the vacuum pump 205 and the solenoid valve 209 are powered on and used normally. The liquid pump 104, the uniform speed motor 109, the forward and reverse motor 112, the infrared sensor 202, the telescopic cylinder 203, the vacuum pump 205 and the solenoid valve 209 can be controlled to start and stop through the control panel. The control procedures involved in the present invention can be implemented by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the present invention.

[0039] Working principle:

[0040] When pasting the PTC heating film, the backing material layer of the PTC heating film is placed on the placement plate 101, so that the side of the backing material layer is opposite to the glue dropper 107, and the liquid pump 104 is started. The liquid pump 104 generates negative pressure suction inside the liquid extraction tube 105, and the liquid extraction tube 105 extracts the glue inside the liquid storage tank 103 and discharges it to the delivery pipe 106 through the liquid pump 104. The delivery pipe 106 delivers the glue to the glue dropper 107, and the glue is discharged through the glue dropper 107 and drips on the side of the backing material layer, ensuring that the amount of glue is evenly discharged, solving the problem of excessive or insufficient extrusion during the manual glue dripping process, and eliminating the need to squeeze the glue multiple times, thereby improving the glue dripping work efficiency.

[0041] When the glue dripping on one side of the backing material layer is completed, since the backing material layer has four sides, the uniform speed motor 109 is started to drive the rotating shaft 110 to rotate at a uniform speed inside the rotating hole, that is, the rotating shaft 110 drives the placement plate 101 and the backing material layer placed on the top to rotate at a uniform speed. After the backing material layer is rotated and adjusted, the glue dripping work can be completed on the other three sides of the backing material layer to ensure that the pasting area of ​​the backing material layer is dripped with glue. When the glue is dripped on the side of the backing material layer, the forward and reverse motors 112 are started to drive the threaded screw 113 to rotate forward, and the threaded screw 113 and the screw hole 115 are threaded to rotate, driving the support The support rod 114, the first chassis 108, the placement plate 101 and the lining material layer placed on the top move to the right. When the glue dropper 107 drops glue, the glue can be evenly dropped at different positions on the side of the lining material layer to avoid the glue gathering in one place, and ensure that the glue dropped on the side of the lining material layer is in a straight line. The threaded screw 113 can drive the support rod 114, the first chassis 108, the placement plate 101 and the lining material layer placed on the top to move left and right and adjust their positions. They can be adjusted and used according to the needs during the glue drop process to facilitate even glue drop on the four sides of the lining material layer.

[0042] After evenly dripping glue on the four sides of the backing material layer, the protective layer of the PTC heating film is placed on the bottom of the vacuum suction cup 201, and the protective layer is firmly sucked and placed by the vacuum suction cup 201. At this time, the forward and reverse motor 112 is started to drive the threaded screw 113 to rotate forward, and the threaded screw 113 and the screw hole 115 are threadedly rotated, driving the support rod 114, the first chassis 108, the placement plate 101 and the backing material layer placed on the top to move to the right, so that the placement plate 101 moves to the bottom of the pressing plate 2. When the shielding plate 3 is aligned with the infrared sensor 202 at the outer end of the pressing plate 2, the infrared rays emitted by the infrared sensor 202 will be blocked by the shielding plate 3, reflecting The amount of radiation coming back will change, thereby triggering induction, that is, the infrared sensor 202 sends an electrical signal to the control panel and processes the information. The control panel will turn off the forward and reverse motors 112 and start the telescopic cylinder 203. The telescopic cylinder 203 drives the telescopic rod 204 to move downward. The telescopic rod 204 pushes the pressing plate 2, the vacuum suction cup 201 and the protective layer to move downward and contact the bottom lining material layer, so that the protective layer and the bottom lining material layer are positioned and pasted together. When the pressing plate 2 is pressed, the protective layer and the bottom lining material layer can be pressed and pasted together, without the need for multiple rework and pasting, to avoid glue overflowing from the bottom lining material layer and the outside of the protective layer to cause waste.
