Description

Technical Field

[0001] This invention relates to the field of electrothermal film production equipment technology, and in particular to a testing device and a cutting machine. Background Technology

[0002] An electrothermal film is a thin film that generates heat when electricity is applied. It is a planar heating element composed of electrically insulating material and a heating resistor material encapsulated within it. The resistance value of the electrothermal film can be used to judge its performance qualification. Specifically, the resistance performance of the electrothermal film is an important indicator for the product performance, including service life and stability. Therefore, in the manufacturing process of electrothermal films, a special resistance testing step is required to confirm the yield rate of the electrothermal film.

[0003] In existing production workshops, the resistance of the heating film is generally measured manually. Specifically, the worker places the heating film on a table and then uses the black and red probes of a multimeter to contact the electrodes at both ends of the heating film. The resistance value of each heating film is calculated based on the value displayed by the multimeter. However, this manual measurement method is prone to errors because the force and angle applied to the electrodes at both ends of the heating film cannot be completely consistent each time. Furthermore, manual measurement is inefficient, labor-intensive, and costly.

[0004] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

Detailed Implementation

[0023] This invention provides a detection device and a cutting machine. To make the purpose, technical solution and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In the description of this invention, it should be understood that the terms "top," "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and should not be construed as limiting this invention; in addition, the terms "installation," "connection," etc. should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Please see Figures 1 to 3 This invention provides a detection device, including a first fixed rod 1, on which a controller 2 is disposed, and a distance detection mechanism and a third driving mechanism are electrically connected to the controller 2 respectively. The distance detection mechanism is used to detect the transmission distance of the electrothermal film. A resistance detection mechanism is disposed on the front side of the first fixed rod 1, and the third driving mechanism is drivenly connected to the resistance detection mechanism to drive the resistance detection mechanism to perform lifting and lowering movements. The resistance detection mechanism is electrically connected to the controller 2. In one embodiment, the controller 2 includes a housing, and a control circuit board is disposed inside the housing. The control circuit board is provided with multiple control chips, and the control chips may be STM32 series control chips.

[0026] In actual operation, the detection device disclosed in this application is set at the feeding end of the cutting machine. The cutting machine can drive the heating film to move in the cutting direction and cut the heating film. The controller 2 is electrically connected to the control device of the cutting machine. The moving distance of the heating film is detected by the distance detection mechanism. When the distance detection mechanism feeds back a signal to the controller 2, the controller 2 feeds back a signal to the control device to control the cutting machine to stop the conveying of the heating film and cut the heating film to ensure that the cutting length of the heating film is consistent with the preset length. When the heating film stops conveying, the controller 2 controls the third drive mechanism to start working. The third drive mechanism drives the resistance detection mechanism to move downward to perform resistance detection on the heating film to be cut. The controller 2 outputs the detection result, which facilitates the sorting of the cut and unqualified heating film by the staff, improves production efficiency and reduces the labor intensity of the staff.

[0027] In one embodiment, the controller 2 is equipped with two indicator lights, which display different colors. The controller 2 controls the different indicator lights to light up according to the information fed back by the resistance detection mechanism. The staff can use the different colored indicator lights to confirm whether the cut electric heating film is a qualified product.

[0028] Further, please refer to Figure 2 The detection device further includes a second drive mechanism and a marking mechanism located on the discharge side of the first fixed rod 1. The second drive mechanism is connected to the marking mechanism for driving the marking mechanism to move up and down. The second drive mechanism is electrically connected to the controller 2. When the information fed back by the resistance detection mechanism indicates that the resistance value of the electric heating film to be cut is unqualified, and when the cutting machine completes the cutting of the previous electric heating film and re-executes the electric heating film conveying, the controller 2 controls the second drive mechanism to start working. The second drive mechanism drives the marking mechanism to move downward to mark the electric heating film to be cut, making the detection results more intuitive and facilitating the staff to distinguish between qualified and unqualified electric heating films during sorting. When the working time preset in the controller 2 is reached, such as after the second drive mechanism has worked for 2 seconds, the second drive mechanism drives the marking mechanism to reset.

[0029] Further, please refer to Figure 2The second driving mechanism includes two second driving groups and a second fixed rod 61 disposed between the two second driving groups; the second driving group includes a second slider 62, a second driving cylinder 63, and a second fixed block 64. The second driving cylinder 63 is fixed to the top of the second slider 62, and the extension rod of the second driving cylinder 63 is connected to the second fixed block 64. The two ends of the second fixed rod 61 are respectively connected to the two second fixed blocks 64. The marking mechanism includes a second mounting base 71 and a marking pen 72. The second mounting base 71 is slidably disposed on the second fixed rod 61, and the marking pen 72 is detachably disposed at the bottom of the second mounting base 71, which facilitates the replacement of the marking pen 72 and the adjustment of the height of the marking pen 72. The second driving cylinder 63 is electrically connected to the controller 2. In one embodiment, the second driving cylinder 63 is bolted to the second slider 62, and the second fixed block 64 is welded to the second driving cylinder 63 and the second fixed rod 61 respectively. The marking pen 72 is bolted to the second mounting base 71, and the marking pen can be a marker pen.

[0030] When it is necessary to mark the electrothermal film to be cut, the controller 2 controls the second drive cylinder 63 to start working. The extension rod of the second drive cylinder 63 retracts, driving the marking pen 72 to move downward. The marking pen 72 contacts the electrothermal film to make a mark. When the working time preset in the controller 2 is reached, the extension rod of the second drive cylinder 63 extends, driving the marking pen 72 to reset.

[0031] In actual operation, the cutting machine is provided with slide bars on both sides, and the two second sliders 62 are respectively connected to the two slide bars. The second sliders 62 can slide on the slide bars. The second sliders 62 are provided with second fixing holes, and the second sliders 62 are fixedly connected to the slide bars through the second fixing holes. By adjusting the position of the second sliders 62 on the slide bars, the distance between the second fixing rod 61 and the first fixing rod 1 can be adjusted, improving the working flexibility of the detection device. The second mounting base 71 is provided with a second mounting hole, and the second mounting base 71 is bolted to the second fixing rod 61 through the second mounting hole. By adjusting the position of the second mounting base 71 on the second fixing rod 61, the marking position of the marking pen 72 can be adjusted, improving the working flexibility of the detection device.

[0032] Further, please refer to Figure 1The detection device further includes a first drive mechanism electrically connected to the controller 2. The first drive mechanism is tractively connected to the first fixed rod 1 and is used to drive the first fixed rod 1 to move up and down. A pressing mechanism is also provided on the first fixed rod 1. The pressing mechanism is used to press the electric heating film during transmission. After the cutting of a roll of electric heating film is completed, the controller 2 controls the first drive mechanism to start working. The first drive mechanism drives the first fixed rod 1 to move upward, so that the bottom of the pressing mechanism is a certain distance away from the cutting machine, which is convenient for the staff to place new electric heating film to be cut. When the cutting machine starts to move the electric heating film in the cutting direction, the first drive mechanism drives the first fixed rod 1 to move downward, so that the pressing mechanism presses the electric heating film again. The pressing mechanism is set to press the electric heating film to prevent the electric heating film from shifting during the cutting process and improve the cutting effect of the cutting machine on the electric heating film.

[0033] Further, please refer to Figure 1 The first driving mechanism includes two first driving groups. Each first driving group includes a first slider 81, a first driving cylinder 82, and a first fixing block 83. The first driving cylinder 82 is disposed on the top of the first slider 81. The extension rod of the first driving cylinder 82 is connected to the first fixing block 83. Both ends of the first fixing rod 82 are respectively fixedly connected to the two first fixing blocks 83. The first driving cylinder 82 is electrically connected to the controller 2. The clamping mechanism includes two clamping groups, which are respectively located on both sides of the distance detection mechanism. Each clamping group includes a third mounting base 91 and a connecting block 9. 2. A pressure wheel 93 is provided. The third mounting base 91 is slidably disposed on the first fixing rod 1. One end of the connecting block 92 is detachably connected to the third mounting base 91, and the pressure wheel 93 is rotatably disposed on the other end of the connecting block 92. In one embodiment, the first driving cylinder 82 is bolted to the first slider 81, and the first fixing block 83 is welded to the first driving cylinder 82 and the first fixing rod 1 respectively. The connecting block 92 is an L-shaped connecting block 92, which is bolted to the third mounting base 91. The pressure wheel 93 is connected to the connecting block 92 through a bearing.

[0034] When it is necessary to press the heating film, the controller 2 controls the first drive cylinder 82 to start working. The extension rod of the first drive cylinder 82 retracts, driving the first fixed rod 1 to move downward, so that the pressing wheel 93 contacts the heating film and presses the heating film. During the process of the heating film being transported in the cutting direction, the pressing wheel 93 rotates relative to the connecting block 92. The outer side of the pressing wheel 93 is provided with a rubber layer, which can increase the friction between the pressing wheel 93 and the heating film and effectively prevent the heating film from shifting. After the cutting of a roll of heating film is completed, the extension rod of the first drive cylinder 82 extends, driving the first fixed rod 1 to move upward. There is a certain distance between the pressing wheel 93 and the bottom of the cutting machine, which facilitates the placement of new heating film.

[0035] In actual operation, the two first sliders 81 are respectively connected to the slide bars on both sides of the cutting machine, and the first sliders 81 can slide on the slide bars; the first sliders 81 are provided with first fixing holes, and the first sliders 81 are bolted to the slide bars through the first fixing holes; by adjusting the position of the first sliders 81 on the slide bars, the position of the first fixing rod 1 can be adjusted to adjust the detection range of the distance detection mechanism and improve the working flexibility of the detection device; the third mounting base 91 is provided with a third mounting hole, and the third mounting base 91 is bolted to the first fixing rod 1 through the third mounting hole; by adjusting the position of the third mounting base 91 on the first fixing rod 1, the position of the pressure roller 93 can be adjusted to press the electric heating film of different widths, thereby improving the working flexibility of the detection device.

[0036] Further, please refer to Figure 1 The distance detection mechanism includes a first mounting base 31 and a detection rod 32. The first mounting base 31 is slidably disposed on the first fixed rod 1. A first through hole is provided on the first mounting base 31, and the detection rod 32 passes through the first through hole. The detection rod 32 is detachably connected to the first through hole. An infrared sensor is provided at the bottom of the detection rod 32. The infrared sensor is electrically connected to the controller 2, and the controller 2 is fixed on the first mounting base 31. In one embodiment, the infrared sensor is glued to the detection rod 32.

[0037] In actual operation, the electrothermal film is provided with multiple parallel heating resistor materials. When the heating resistor material moves directly below the infrared sensor, the infrared sensor feeds back a signal to the controller 2. The controller 2 records the number of times the infrared sensor feeds back the signal to confirm the transmission length of the electrothermal film.

[0038] In actual operation, the first mounting base 31 is also provided with a first mounting hole and a second through hole. The first mounting base 31 is bolted to the first fixing rod 1 through the first mounting hole. By adjusting the position of the first mounting base 31 on the first fixing rod 1, the detection position of the detection rod 32 can be adjusted. Furthermore, the first through hole and the second through hole are connected. The detection rod 32 is fixed by the fixing screw and the second through hole. By adjusting the position of the detection rod 32 in the first through hole, the detection range of the detection rod 32 can be adjusted, thereby improving the working flexibility of the detection device.

In one embodiment, the third driving mechanism is bolted to the fixing frame, the fixing frame is bolted to the first fixed rod 1, and the driving bracket 42 is welded to the third driving cylinder 41.

[0040] When resistance detection is required, controller 2 controls the extension rod of the third drive cylinder 41 to extend, driving the drive bracket 42 and the resistance detection mechanism to move downward, so that the resistance detection mechanism contacts the heating film and the resistance value is detected; when the heating film starts to transmit again, controller 2 controls the extension rod of the third drive cylinder 41 to retract, driving the resistance detection mechanism to move upward, so that the resistance detection mechanism does not contact the heating film.

[0041] Further, please refer to Figure 1 and Figure 3The resistance detection mechanism includes a third fixed rod 51, a detection probe 52, and a guide block 53. The third fixed rod 51 is fixed to the bottom of the drive bracket 42, and a sliding groove 511 is formed on the third fixed rod 51.

[0043] In actual operation, the connecting seat 11 is slidably mounted on the first fixed rod 1 and fixedly connected to the first fixed rod 1 by bolts; resistance detection mechanisms of different widths can be selected according to the actual width of the electric heating film. By adjusting the position of the first fixed rod 1 on the connecting seat 11, the connecting seat 11 can be connected to the third fixed rod 51 of different widths, thereby improving the flexibility of the detection device during operation.
