Abstract
Description
Technical Field
[0001] The utility model relates to a detection device, in particular to a film detection flattening device. Background Art
[0002] For the detection of film products, a projector is mainly used. For example, for the detection of lithium battery separators, a projector is mainly used, and the condition of holes is detected by the lighting lamp below the projector. During the inspection by the projector, since the film is prone to wrinkling, unevenness, etc., these conditions will lead to inaccurate detection results and affect the reliability of the detection. Therefore, it is necessary to keep the lithium battery separator in a flat state during detection.
[0003] In the existing detection, in order to keep the lithium battery separator flat, the separator is usually attached to the detection glass of the projector with tape. Usually, one end of the film is first attached to the detection glass with tape, and then the separator is pulled and the other end of the separator is attached to the detection glass with tape. This process is rather cumbersome. After the detection is completed, the tape needs to be torn off, and the separator is easily damaged when tearing off the tape. In addition, the separator will be deformed during the process of pulling the separator, which also affects the accuracy and reliability of the detection results. Content of the Utility Model

[0020] The present utility model will now be further described in conjunction with the accompanying drawings.
[0021] As Figures 1 to 5As shown in the figure, a film detection flattening device includes a rotating device 4, a flattening frame 1, a transparent plate 2, and a flipping device 3. The rotating device 4 is installed on the detection table of the projector and is located behind the detection table; one end of the flattening frame 1 is installed on the rotating device 4, and the other end is connected to the flipping device 3. The flattening frame 1 is also located above the detection glass of the projector, and a transparent plate 2 is installed on the flattening frame 1. The transparent plate 2 can be glass, a transparent plastic plate, etc., and the surface of the transparent plate 2 needs to be flat. The detection glass is installed on the detection table, and the flipping device 3 is also installed on the detection table and is located in front of the detection table. The flipping device 3 is used to flatten the film on the projector with the transparent plate 2 and to place the film after the transparent plate 2 is flipped.
[0022] The flipping device 3 can drive the flattening frame 1 to flip by a certain angle, that is, to form a certain angle between the transparent plate 2 and the detection glass, so that the transparent plate 2 is in an inclined state, which is convenient for placing the film on the detection glass and taking out the film after the detection is completed. During the detection, the flipping device 3 drives the flattening frame 1 and the transparent plate 2 to press against the detection glass. The transparent plate 2 flattens the film on the detection glass. The transparent plate 2 keeps the film in a flat state and enables the film not to be subjected to tensile force. The film can be both in a flat state and in a free state, reducing the influence of the outside world on the film detection, thereby improving the reliability and accuracy of the film detection. Since there is no need to use tape to keep the film in a flat state, the detection steps are simplified and the detection efficiency is improved.
[0023] To facilitate the rotation of the flattening frame 1 and keep the rotation axis unchanged, the rotating device 4 includes a bearing seat 41 and a rotating shaft 42. The bearing seat 41 is fixed on the detection table and is located on both sides of the detection glass. One end of the rotating shaft 42 is installed on the bearing seat 41, and the other end of the rotating shaft 42 is connected to the flattening frame 1.
[0024] To prevent the flattening frame 1 from moving axially along the rotating shaft 42, the rotating device 4 further includes a positioning ring 43. The positioning ring 43 is installed on the rotating shaft 42 and is located between the bearing of the flattening frame 1 and the bearing seat 41.
[0025] The flipping device 3 is symmetrically located on both sides of the detection table. The flipping device 3 includes a flipping base 31, a flipping cylinder 32, a ball eye joint 33, and a flipping shaft 34. The flipping base 31 is fixed on the detection table and is located on both sides of the detection glass. The flipping base 31 is rotatably connected to the tail of the flipping cylinder 32; the end of the piston rod of the flipping cylinder 32 is connected to the ball eye joint 33, and the ball eye joint 33 is connected to one end of the flipping shaft 34. The other end of the flipping shaft 34 is fixed on the flattening frame 1. When the piston rod of the flipping cylinder 32 extends, the flattening frame 1 flips upward above the detection glass. When the piston rod of the flipping cylinder 32 retracts, the flattening frame 1 presses against the detection glass.
[0026] To improve the strength of the flattening frame 1, strengthening protrusions 11 are provided on the flattening frame 1. The strengthening protrusions 11 are located on one side of the flipping shaft 34. The strengthening protrusions 11 can prevent the flattening frame 1 from deforming, thereby ensuring the reliability of the flattening film. The flattening frame 1 is formed by bending a sheet.
[0027] The flattening frame 1 is provided with a connecting groove 12 and mounting holes 13 provided at the bottom of the connecting groove 12. The transparent plate 2 is installed in the mounting holes 13, and the transparent plate 2 protrudes from the bottom surface of the flattening frame 1. The connecting groove 12 facilitates the fixing of the transparent plate 2, and the mounting holes 13 facilitate the transparent plate 2 to protrude from the bottom surface of the flattening frame 1. The fact that the transparent plate 2 protrudes from the flattening frame 1 can ensure that the film is pressed on the detection glass, preventing the flattening frame 1 from touching the detection glass and causing the transparent plate 2 to be unable to press the film flat on the detection glass.
[0028] To facilitate the installation of the transparent plate 2 and ensure that the transparent plate 2 can protrude from the flattening frame 1, the film detection and flattening device further includes a connecting device 5. The connecting device 5 is respectively connected to the transparent plate 2 and the flattening frame 1. Specifically, the connecting device 5 includes a backing plate 51, a connecting plate 52, a first screw 53, and a second screw 54. The backing plate 51 is welded in the connecting groove 12 of the flattening frame 1, and a first threaded hole is provided on the backing plate 51. The first screw 53 passes through the connecting plate 52 and is connected to the first threaded hole. The first screw 53 fixes the connecting plate 52 on the backing plate 51. The backing plate 51 makes the transparent plate 2 protrude from the bottom surface of the flattening frame 1, and the backing plate 51 also facilitates the installation of the first screw 53. The transparent plate 2 is provided with a counterbore 21. The second screw 54 is a countersunk head screw. The second screw 54 is inserted into the counterbore 21 and is connected to the second threaded hole on the connecting plate 52. The second screw 54 fixes the transparent plate 2 on the connecting plate 52. Since the second screw 54 is a countersunk head screw, it can not only prevent the screw from protruding from the transparent plate 2, but also facilitate the fixing of the transparent plate 2, improve the connection strength between the transparent plate 2 and the connecting plate 52, and avoid opening threaded holes on the transparent plate 2.
[0029] During detection, the flipping cylinder 32 is started. The piston rod of the flipping cylinder 32 extends. The piston rod drives the flattening frame 1 to rotate through the ball eye joint 33 and the rotating shaft 42. The flattening frame 1 and the transparent plate 2 rotate to an inclined state. Then the film is placed on the detection glass and the film is made as flat as possible. Next, the flipping cylinder 32 is started again. The piston rod of the flipping cylinder 32 retracts. The transparent plate 2 presses the film tightly on the detection glass. The film automatically becomes flat under the pressure of the transparent plate 2. Then the detection is carried out. After the detection is completed, the flipping cylinder 32 is started again to open the transparent plate 2 and take out the film.

These descriptions are only for explaining the principle of the present utility model and cannot be construed as a limitation to the protection scope of the present utility model in any way. Based on the explanations herein, those skilled in the art can think of other specific implementation manners of the present utility model without creative efforts, and these manners will all fall within the protection scope of the claims of the present utility model.
