DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0028] Embodiment 1

[0029] With reference to Figures 1-5 A detection device mainly comprises a bracket 1, and a handrail 7 is fixedly installed on one side of the bracket 1 so as to facilitate an operator to hold or operate the device. In order to realize clamping and positioning, pulling and comprehensive detection of a flexible circuit board, the detection device further comprises the following structures:

[0030] A clamping mechanism part, which comprises a bottom clamping plate 2 and a mounting plate 3 located above the bottom clamping plate 2, and two screw assemblies are symmetrically connected to the mounting plate 3. Each screw assembly is composed of a nut 4 fixedly installed on the top of the mounting plate 3 and a screw rod 5 penetrating through the nut 4 and being threadedly connected. The bottom end of the screw rod 5 extends below the mounting plate 3 and is rotationally connected to the top of an upper clamping plate 6. In use, one side edge of the flexible circuit board is placed on the bottom clamping plate 2, and then the two screw rods 5 are simultaneously rotated. Due to the threaded transmission action of the screw rod 5 and the nut 4, the screw rod 5 moves downward, thereby driving the upper clamping plate 6 to move downward, until the bottom clamping plate 2 and the upper clamping plate 6 cooperatively clamp one side edge of the flexible circuit board, and the positioning is completed.

[0031] A pulling mechanism part, which comprises two slide rails 8 fixedly installed on the inner walls of the two sides of the bracket 1, and a slide bar 9 is slidably connected to each slide rail 8. A detection mechanism is connected to the two slide bars 9, specifically by fixedly connecting a moving plate 10 of the detection mechanism to one side of the two slide bars 9 close to each other. In addition, the top of the two slide bars 9 is fixedly installed with a same connecting plate 19, and the top of the connecting plate 19 is fixedly installed with a ball head rod 20. In operation, the operator can pull the ball head rod 20 to drive the connecting plate 19 to move horizontally, thereby driving the two slide bars 9 and the detection mechanism connected thereto to move horizontally in the bracket 1.

[0032] The detection mechanism part is specifically constructed as follows: the top of the moving plate 10 is fixedly provided with a support frame 11, and a scale rod 12 is slidably connected through the top inner wall of the support frame 11. The bottom end of the scale rod 12 extends to the lower side of the moving plate 10 and is fixedly provided with a detection rod 16, which is in contact with the top of the flexible circuit board. A tension spring 18 is sleeved on the scale rod 12 and located in the support frame 11, and the top end and the bottom end of the tension spring 18 are fixedly connected with the scale rod 12 and the top of the moving plate 10 respectively. Under the action of the tension of the tension spring 18, the scale rod 12 has a downward thrust, so that the detection rod 16 always keeps in contact with the top of the flexible circuit board. When the moving plate 10 moves with the two sliding bars 9, the detection rod 16 moves transversely along the flexible circuit board, so as to detect the thickness of the flexible circuit board. If the thickness of a certain area of the flexible circuit board changes, the height of the detection rod 16 will change, thereby driving the scale rod 12 to move longitudinally. At this time, the change amount of the thickness of the flexible circuit board can be detected by referring to the scale on the scale rod 12.

[0033] The present application can be used in the field of circuit board detection, and can also be used in other fields applicable to the present application.

[0034] Embodiment 2

[0035] Reference Figure 5 On the basis of embodiment one, an improved soft circuit board thickness detection device is applied to the field of circuit board detection. In order to improve the detection accuracy, the top end of the scale rod 12 is further fixedly provided with a support plate 13, and two distance sensors 14 are symmetrically fixedly installed on the bottom of the support plate 13. Two baffles 15 are symmetrically fixedly installed on the top of the support frame 11, and the distance sensors 14 are matched with the corresponding baffles 15. A display screen 17 is fixedly installed on one side of the bracket 1, and the display screen 17 is electrically connected with the two distance sensors 14 respectively. When the support plate 13 moves longitudinally with the scale rod 12, the two distance sensors 14 move longitudinally. At this time, under the reference of the corresponding baffles 15, the distance sensors 14 can measure the displacement amount thereof and transmit the measured data to the display screen 17. In this way, the operator can directly observe the change amount of the thickness of the flexible circuit board.

[0036] However, as known to those skilled in the art, the working principle and wiring method of the distance sensor 14 and the display screen 17 are common, which belong to conventional means or common knowledge, and will not be described here. Those skilled in the art can arbitrarily select and match according to their needs or convenience.

[0037] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
