Description

Technical Field

[0001] The utility model relates to the technical field of electric heating film withstand voltage test, in particular to a tool for withstand voltage test of electric heating film finished products. Background Art

[0002] Electric heating film is a commonly used electronic device in heating systems. Before leaving the factory, the finished electric heating film generally needs to undergo a series of tests to ensure the product's factory quality and the stability of various electric heating properties. The voltage test is an indispensable test link.

[0003] Currently, traditional pressure-testing tooling for finished heating film products involves manually placing the film under test under a testing machine. The film is then flattened and positioned using traditional fixing components (such as rollers), and then subjected to a pressure test using a tester. However, the roller-pressing method is ineffective for flattening heating films that are already wrinkled or prone to wrinkling. Manual flattening increases the number of steps required, limiting the efficiency and accuracy of the test process and reducing overall test efficiency. Utility Model Content

[0020] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0021] The following describes the pressure test tool for the finished product of the electric heating film according to the embodiment of the present invention with reference to the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, the pressure test tool for the finished product of the electric heating film according to the embodiment of the present invention may include a base 10 , a movable frame 20 , a positioning assembly 30 and a tester 40 .

[0023] A groove 11 is formed transversely on the top surface of the base body 10 , and two linear rails 12 are symmetrically provided on both sides of the groove 11 . The linear rails 12 are provided with a sliding telescopic assembly 50 .

[0024] The movable frame 20 is disposed longitudinally, and both ends thereof are slidably disposed on corresponding linear rails 12 . Both longitudinal ends of the movable frame 20 are connected to corresponding sliding telescopic components 50 .

[0025] It should be noted that the mobile frame 20 described in this embodiment can drive the sliding telescopic assembly 50 to extend and retract accordingly during the lateral movement, thereby facilitating the stability of the movement of the mobile frame 20. In addition, the provided sliding telescopic assembly 50 can limit the movement distance of the mobile frame 20, thereby allowing the mobile frame 20 to move within the designated groove 11.

[0026] The positioning assembly 30 includes a first roller 31 and a second roller 32 which are movably arranged on the movable frame 20 in sequence and transversely, wherein the first roller 31 and the second roller 32 are both in sliding contact with the bottom wall of the groove 11, and a torsion spring 70 is provided between the first roller 31 and the movable frame 20. A connecting frame 22 movably connected to the second roller 32 is provided on the movable frame 20, and the connecting frame 22 is rotatably connected to the movable frame 20.

[0027] The tester 40 is provided on the test hole 21 on the movable frame 20, and the tester 40 is located between the first roller 31 and the second roller 32. It should be noted that the tester 40 described in this embodiment can perform a withstand voltage test on the electric heating film. The tester 40 is prior art and will not be described in detail here.

[0028] It should be noted that the connecting frame 22 described in this embodiment is movably connected to the second roller 32 and is rotationally connected to the movable frame 20. When only the second roller 32 is fixed, the first roller 31 can rotate accordingly relative to the movable frame 20, and during the rotation of the first roller 31, the movable frame 20 can rotate accordingly relative to the connecting frame 22.

[0029] It should be noted that after the relevant personnel control the movable frame 20 to move a certain distance, they press the second roller 32 to keep it stable. At this time, the position of the movable frame 20 is fixed. The first roller 31 described in this embodiment can rotate in the opposite direction and reset under the action of the torsion spring 70. During the process, the electric heating film between it and the second roller 32 can be leveled, thereby realizing the wrinkle removal and leveling operation of the test part of the electric heating film.

[0030] Specifically, in the actual process of performing a pressure test on the electric heating film, the relevant personnel first place one end of the electric heating film (usually in a rolled-up state) in the groove 11 and in front of the first roller 31, and then control the movable frame 20 to move so that the first roller 31 and the second roller 32 move together and roll the electric heating film. When they reach the appropriate position, the relevant personnel can control the second roller 32 to be fixed by pressing. At this time, the first roller 31 can be rotated in the opposite direction and reset under the action of the torsion spring 70. In the process, the electric heating film between it and the second roller 32 can be leveled, thereby achieving the wrinkle removal and leveling operation of the test part of the electric heating film.

[0031] After the electric heating film is flattened and positioned, the movable frame 20 , the first roller 31 and the second roller 32 are all in a stationary state. At this time, relevant personnel can use the tester 40 to perform a pressure test on the flattened electric heating film in the test hole 21 .

[0032] In one embodiment of the present invention, Figure 1 As shown, the sliding telescopic assembly 50 may include at least two sliders 51 and a bending piece, wherein the two sliders 51 are arranged on the corresponding linear rails 12 for sliding transversely in sequence, and the two sliders 51 on both sides are respectively connected to the linear rails 12 and the movable frame 20, and the bending piece is arranged between the two sliders 51, and the bending piece includes two rotatably connected connecting plates 52, wherein the free ends of the two connecting plates 52 are respectively rotatably connected to the corresponding sliders 51.

[0033] Specifically, when the relevant personnel manipulate the mobile rack 20 to move horizontally, it can drive the slider 51 connected to it to slide on the corresponding linear track 12. During the process, the slider 51 can drive the two connections to rotate, thereby changing the distance between the two sliders 51, thereby adapting to the movement of the mobile rack 20.

[0034] In one embodiment of the present invention, a soft layer (not shown) is provided on the outer sides of the first roller 31 and the second roller 32. It should be noted that the soft layer described in this embodiment can be a rubber layer, a silicone layer, etc., so that the soft layer can maintain contact with the electric heating film while protecting the electric heating film, thereby facilitating the flattening and positioning of the electric heating film.

[0035] In one embodiment of the present invention, Figure 1 As shown, a protective cover 80 is provided on the outer side of the first roller 31, and the protective cover 80 is connected to the movable frame 20. It can be understood that the protective cover 80 can provide protection for the first roller 31.

[0036] In one embodiment of the present invention, Figure 1 As shown, a handle 60 is provided on the movable frame 20. It can be understood that the provided handle 60 can conveniently control the lateral movement of the movable frame 20.

[0037] In summary, the finished product pressure test tooling of the electric heating film in the embodiment of the present invention can drive the positioning component to efficiently flatten and position the electric heating film through the movable frame, so that the tester can perform stable pressure test on the electric heating film, thereby significantly improving the efficiency and reliability of the pressure test.
