Description

Technical Field

[0001] This invention relates to the field of electrothermal film processing technology, and in particular to a single electrothermal film power testing platform. Background Technology

[0002] Low-temperature electric heating film is a semi-transparent polyester film that generates heat when electricity is applied. It is made by processing and hot-pressing conductive special ink and metal current-carrying strips between insulating polyester films. When in operation, the electric heating film acts as the heating element, sending heat into the space in the form of radiation, so that people and objects are warmed first. Its overall effect is better than traditional convection heating methods.

[0003] Electric heating films are typically designed with a target power output. Testing confirms whether the actual power matches the design, ensuring the product achieves the expected heating efficiency. During production, minor variations may affect the performance of the electric heating film. By testing each piece of electric heating film, manufacturers can guarantee consistent performance across all products. This is crucial for mass production and quality control. Excessive power can lead to safety hazards such as overheating, fire, or electric shock. Therefore, single-piece power testing of electric heating films is an important quality control step, ensuring that the film does not exceed safe operating limits, thus protecting user safety.

[0004] Existing methods for testing the power of a single electrothermal film mostly involve manually measuring the resistance of each heating unit in the film using resistance measuring equipment before calculating the resistance of the entire film. This process is time-consuming, and errors can occur because the contact surfaces may not make full contact during testing. Therefore, there is an urgent need to develop a corresponding electrothermal film power testing platform to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide a power testing platform for a single electrothermal film in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A single-piece power testing platform for an electrothermal film includes a base, an electrothermal film under test, and an electrical measurement component. The resistance measurement component includes a DC low-resistance tester, terminals, and connecting wires. A guide rod and a base plate are fixedly connected to the top of the base. Two sets of movable stages are slidably connected to the outer wall of the guide rod. A translation component for adjusting the horizontal position of the two sets of movable stages is provided on the top of the base. A pusher is fixedly connected to the top of each set of movable stages via a mounting platform. A copper sheet is fixedly connected to the output end of the pusher via a support platform. The two sets of copper sheets are electrically connected to two sets of connecting wires. An elastic insulating pad is fixedly connected between the two sets of movable stages. A fixed platform and a smoothing platform are arranged sequentially on the outer side of one set of movable stages. A positioning component for positioning the electrothermal film under test is provided inside both the fixed platform and the smoothing platform. A slot that fits the contour of one side of the electrothermal film under test is provided on the bottom of the fixed platform.

[0008] Preferably, a horizontal chamber is fixedly connected to the top of the base, a drive rod is rotatably connected to the inner wall of the horizontal chamber, and an adjustment part for adjusting the angle of the DC low resistance tester is provided on the outer wall of the drive rod.

[0009] Preferably, the adjustment part includes a slider that is screwed to the outer wall of the drive rod, a push rod is hinged to the top of the slider, a connecting shell is provided on the outer wall of the DC low resistance tester, and the top of the push rod is hinged to the bottom of the connecting shell.

[0010] Preferably, the translation component includes a driving member fixedly connected to the top of the base, a screw fixedly connected to the output end of the driving member, and the outer wall of the screw being screwed into two sets of moving platforms through two sets of opposite threaded grooves.

[0011] Preferably, the outer wall of the longitudinal end of the elastic insulating pad abuts against the inner wall of the longitudinal end of the two sets of moving platforms, and the bottom of each set of moving platforms is fixedly connected with a protrusion that abuts against the outer wall of the horizontal end of the elastic insulating pad.

[0012] Preferably, the other set of the two sets of mobile platforms has magnetic plates embedded on the opposite side of the fixed platform, and metal plates are embedded on both sides of the horizontal end of the platform.

[0013] Preferably, the output end of the pusher is fixedly connected to a T-shaped block that is slidably connected to the inner wall of the mounting platform, and the T-shaped block is fixedly connected to the support platform.

[0014] Preferably, the positioning component includes a positioning plate and a pull rod that rotatably engages with the positioning plate. A spring is fixedly connected to the top of the positioning plate, and the pull rod includes a threaded section and a smooth section. A lifting ring is fixedly connected to the top of the pull rod.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In this application, the terminal block is connected to a DC low resistance tester. The positive and negative terminals of the terminal block are connected to two sets of copper plates via two sets of conductive clamps. An elastic insulating pad is placed on top of the base plate and positioned by two sets of moving platforms and protrusions at the bottom. The heating film to be tested is placed on top of the elastic insulating pad, and one side of the heating film is quickly positioned via a slot. Then, the positioning component on the fixed platform completes the positioning of one side of the heating film to be tested. Next, the platform is pushed until it engages with another set of moving platforms. During this process, the platform will... The heating film to be tested is smoothed out, and then positioned on the other side by the positioning component on the smoothing platform. Then, the pushing component is activated, and two sets of pushing components push two sets of copper sheets through two sets of support platforms until the two sets of copper sheets simultaneously abut against both sides of the multiple carbon paste printing parts on the heating film to be tested. At this time, the total resistance of the heating part of the heating film to be tested will be directly displayed on the DC low resistance tester, thereby improving the convenience of heating film power testing, and achieving the smoothing of the heating film while ensuring the quickness and accuracy of the heating film placement.

[0017] 2. In this application, the base is installed horizontally. Before the operator stands in front of the base to test the electrothermal film, the drive rod is rotated. The outer wall of the drive rod screws into the inner wall of the slider. The slider moves longitudinally due to the constraint of the inner wall of the transverse chamber. At the same time, the two ends of the push rod are rotated and engaged with the connecting shell and the slider, respectively. The push rod changes shape and pushes the connecting shell to deflect around the pin axis until the operator can clearly observe the data displayed on the DC low resistance tester. This allows the DC low resistance tester to be quickly adjusted according to the usage requirements, thereby improving the ease of use of the electrothermal film single-piece power testing platform.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-5 The present invention provides a technical solution:

[0027] A single-piece power testing platform for an electric heating film includes a base 1, an electric heating film 21 to be tested, and an electrical measurement component. The resistance measurement component includes a DC low resistance tester 6, a terminal block 7, and a connecting wire 8. A light rod 2 and a base plate 4 are fixedly connected to the top of the base 1. Two sets of moving platforms 9 are slidably connected to the outer wall of the light rod 2. A translation component for adjusting the horizontal position of the two sets of moving platforms 9 is provided on the top of the base 1. A pusher 13 is fixedly connected to the top of each set of moving platforms 9 through a mounting platform 11. A copper sheet 15 is fixedly connected to the output end of the pusher 13 through a support platform 14. The two sets of copper sheets 15 are electrically connected to the two sets of connecting wires 8. An elastic insulating pad 20 is fixedly connected between the two sets of moving platforms 9. A fixed platform 16 and a smoothing platform 17 are arranged sequentially on the outer side of one of the sets of moving platforms 9. A positioning component for positioning the electric heating film 21 to be tested is provided inside the fixed platform 16 and the smoothing platform 17. A slot 24 that fits the contour of one side of the electric heating film 21 to be tested is opened at the bottom of the fixed platform 16.

[0028] Terminal 7 is connected to DC low resistance tester 6. The positive and negative connecting wires 8 of terminal 7 are connected to two sets of copper plates 15 through two sets of conductive clamps. The elastic insulating pad 20 is placed on top of the base plate 4 and positioned by two sets of moving platforms 9 and the bottom protrusions 22. The heating film 21 to be tested is placed on top of the elastic insulating pad 20, and one side of the heating film 21 to be tested is quickly positioned by the slot 24. Then, the positioning component on the fixed platform 16 completes the positioning of one side of the heating film 21 to be tested. Then, the smoothing platform 17 is pushed until it is combined with another set of moving platforms 9. During this process, the smoothing platform 17 will... The heating film 21 to be tested is smoothed out, and then positioned on the other side of the heating film 21 by the positioning component on the smoothing platform 17. Then, the pusher 13 is activated. The two sets of pushers 13 push the two sets of copper sheets 15 through the two sets of support platforms 14 until the two sets of copper sheets 15 simultaneously abut against both sides of the multiple carbon paste printing parts on the heating film 21 to be tested. At this time, the total resistance of the heating part of the heating film 21 to be tested will be directly displayed on the DC low resistance tester 6, thereby improving the convenience of heating film power testing and ensuring the speed and accuracy of heating film placement while smoothing the heating film.

[0029] It should be noted that the DC low resistance tester 6 used here is the JK2512B model resistance tester, which is equipped with terminal block 7 and connecting wire 8. This is existing technology, so the process of generating resistance data will not be described in detail here.

[0030] Specifically, such as Figure 2 and Figure 4 As shown, a horizontal chamber 10 is fixedly connected to the top of the base 1. A drive rod 12 is rotatably connected to the inner wall of the horizontal chamber 10. An adjustment part for adjusting the angle of the DC low resistance tester 6 is provided on the outer wall of the drive rod 12. The adjustment part includes a slider 18 that is screwed to the outer wall of the drive rod 12. A push rod 19 is hinged to the top of the slider 18. A connecting shell 5 is provided on the outer wall of the DC low resistance tester 6. The connecting shell 5 is connected to the DC low resistance tester 6 by screws, which ensures the rotation of the DC low resistance tester 6 without requiring modification of the DC low resistance tester 6. The top of the push rod 19 is hinged to the bottom of the connecting shell 5. The base 1 is installed horizontally. Before the operator stands in front of the base 1 to test the electrothermal film, the drive rod 12 is rotated. The outer wall of the drive rod 12 is screwed into the inner wall of the slider 18. The slider 18 is constrained by the inner wall of the transverse chamber 10 and moves longitudinally. At the same time, the push rod 19 rotates and engages with the connecting shell 5 and the slider 18 respectively. The push rod 19 changes shape and pushes the connecting shell 5 to deflect around the pin axis until the operator can clearly observe the data displayed on the DC low resistance tester 6. This allows the DC low resistance tester 6 to be quickly adjusted according to the usage requirements, thereby improving the ease of use of the electrothermal film single-piece power testing platform.

[0031] Specifically, such as Figure 2 and Figure 3 As shown, the translation component includes a drive unit fixedly connected to the top of the base 1, and a screw 3 fixedly connected to the output end of the drive unit. The outer wall of the screw 3 is screwed to two sets of moving platforms 9 through two sets of opposite threaded grooves. The relative movement of the two sets of moving platforms 9 is used to adapt to electric heating films of different widths. The elastic insulating pad 20 is replaced accordingly. The outer wall of the longitudinal end of the elastic insulating pad 20 abuts against the inner wall of the longitudinal end of the two sets of moving platforms 9. The bottom of each set of moving platforms 9 is fixedly connected to a protrusion 22 that abuts against the outer wall of the horizontal end of the elastic insulating pad 20, so as to ensure the convenience of assembling and disassembling the elastic insulating pad 20. The other set of moving platforms 9 has a magnetic absorbing plate embedded on the opposite side of the fixed platform 16. The two sides of the horizontal end of the smoothing platform 17 have metal plates embedded, so as to improve the stability of the smoothing platform 17 in the initial stage of the fixed platform 16 and the smoothing platform 17 in the other set of moving platforms 9 by increasing the magnetic attraction.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the output end of the pusher 13 is fixedly connected to a T-shaped block that slides on the inner wall of the mounting platform 11. The T-shaped block is fixedly connected to the support platform 14 to ensure the stability of the movement of the two sets of support platforms 14 and copper plates 15. The positioning assembly includes a positioning plate 23 and a pull rod 27 that rotates with the positioning plate 23. A spring 25 is fixedly connected to the top of the positioning plate 23. The pull rod 27 includes a threaded section and a smooth section, and a lifting ring 26 is fixedly connected to the top of the pull rod 27. Taking the positioning assembly on the fixed platform 16 as an example, the top of the spring 25 and the top of the fixed platform 16 are connected... With the inner wall fixed, the pull rod 27 is pulled by the lifting ring 26, causing the smooth section to slide against the top of the fixed platform 16. Then, the pull rod 27 is rotated by the lifting ring 26, and the threaded section is screwed onto the top of the fixed platform 16. At this time, the positioning piece 23 remains away from the heating film 21 to be tested, and the spring 25 is compressed. At this time, the heating film 21 to be tested can be picked up and put down. Similarly, rotating the pull rod 27 separates the threaded section from the fixed platform 16, and the spring 25 pushes the positioning piece 23 against the top of the heating film 21 to be tested, thereby completing the positioning of the heating film 21 to be tested.

[0033] Working principle: Terminal 7 is connected to DC low resistance tester 6. The positive and negative connecting wires 8 of terminal 7 are connected to two sets of copper sheets 15 through two sets of conductive clamps. The elastic insulating pad 20 is placed on top of the base plate 4 and positioned by two sets of moving platforms 9 and the bottom protrusions 22. The heating film 21 to be tested is placed on top of the elastic insulating pad 20, and one side of the heating film 21 is quickly positioned by the slot 24. Then, the positioning component on the fixed platform 16 completes the positioning of one side of the heating film 21. Next, the smoothing platform 17 is pushed until it is combined with another set of moving platforms 9. During this process, the smoothing platform 17 will smooth the heating film 21 to be tested. The positioning component on the smoothing platform 17 positions the other side of the heating film 21 to be tested. Then, the pushing component 13 is activated. The two pushing components 13 push the two sets of copper sheets 15 through two sets of support platforms 14 until the two sets of copper sheets 15 simultaneously abut against the multiple carbon paste imprints on the heating film 21 to be tested. On both sides of the brush section, the total resistance of the heating part of the heating film 21 under test will be directly displayed on the DC low resistance tester 6, thereby improving the convenience of the heating film power test. At the same time, the heating film is smoothed out, ensuring the quickness and accuracy of the heating film placement. The base 1 is installed horizontally. Before the operator stands in front of the base 1 and tests the heating film, the drive rod 12 is rotated. The outer wall of the drive rod 12 is screwed into the inner wall of the slider 18. The slider 18 is constrained by the inner wall of the transverse chamber 10 and moves longitudinally. At the same time, the push rod 19 rotates with the connecting shell 5 and the slider 18 respectively. The push rod 19 changes shape and pushes the connecting shell 5 to deflect around the pin axis until the operator can clearly observe the data displayed on the DC low resistance tester 6. This allows the DC low resistance tester 6 to be quickly adjusted according to the usage requirements, thereby improving the convenience of using the single-piece power test platform for the heating film.
