Description
Technical Field
[0001] The utility model relates to the technical field of flexible circuit board processing, in particular to a material clamping and leveling device. Background Art
[0002] Flexible circuit board is a kind of printed circuit board with high reliability and excellent flexibility made of polyimide or polyester film as the base material. It is called soft board or FPC for short. It has the characteristics of high wiring density, light weight and thin thickness. FPC and other film materials need to be opened during use.
[0003] When punching a flexible circuit board, it is often necessary to flatten it. In the existing flexible circuit board punching equipment, the clamping and flattening device is composed of two front and rear clamps, and only one clamp can be moved to flatten the flexible circuit board front and back. This arrangement makes the flexible circuit board can only be aligned to the fixed clamp during the clamping process, and the movable clamp is used to flatten it, and then the punching processing head punches according to the punching route. For flexible circuit boards with relatively small widths (the width of the flexible circuit board is less than half the length of the clamping and flattening device for a small width), after clamping and aligning with the fixed clamp, the movable clamp needs to travel a longer distance to clamp, and each moving clamp needs to return to the origin for alignment before clamping. For the clamping and flattening of batches of small-width flexible circuit boards, this takes a lot of time, reduces the clamping and flattening efficiency of flexible circuit boards with smaller widths, and thus reduces the subsequent processing efficiency.
[0004] Therefore, it is necessary to propose a clamping and leveling device to quickly clamp and level flexible circuit boards of different widths to improve processing efficiency. Utility Model Content
[0005] In order to solve the above problems, the utility model proposes a material clamping and leveling device to quickly clamp and level flexible circuit boards of different widths to improve processing efficiency.

The driving device is fixedly connected to the fixed frame and is parallel to the fixed frame. The first clamping mechanism is slidably connected to one end of the fixed frame and forms a screw connection with the rotating shaft of the driving device. The second clamping mechanism is slidably connected to the other end of the fixed frame and forms a detachable connection with an adjustable position to change the fixed position of the second clamping mechanism.
[0008] Furthermore, a first fixing position and a second fixing position are provided at one end of the fixing frame, the first fixing position and the second fixing position are arranged laterally in sequence, and the second clamping mechanism can form a detachable connection with the first fixing position or the second fixing position.
[0009] Furthermore, the first fixing position and the second fixing position are both provided with fixing holes for insertion and fixing.
[0010] Furthermore, a contact switch is provided on the inner side of the fixing frame, and the contact switch is located below the second fixing position.

The back of the sliding frame is slidably connected to one end of the fixed frame, the longitudinal cylinder clamp is fixedly connected to the top of the sliding frame, and the insert fixing component is fixedly connected to one side of the sliding frame and faces the fixed frame. The insert fixing component can form a detachable connection with the first fixed position or the second fixed position to change the fixed position of the second clamping mechanism.

[0015] Furthermore, the clamping assembly also includes a controller, which is fixedly connected to one end of the fixing frame and electrically connected to the driving device.
[0016] Beneficial effects of the utility model:
[0017] The utility model uses the second clamping mechanism as a fixed and position-adjustable clamping head, and the first clamping mechanism as a movable clamping head. After the first clamping mechanism and the second clamping mechanism both clamp the flexible circuit board, the first clamping mechanism is driven by a driving device to move backward to flatten the flexible circuit board. For flexible circuit boards with smaller widths, the fixed position of the second clamping mechanism can be adjusted to make it closer to the first clamping mechanism.

DETAILED DESCRIPTION
[0024] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.
[0025] Please refer to Figure 1-Figure 4The utility model proposes a material clamping and flattening device, comprising two clamping components 1, the two clamping components 1 are arranged in an arranged manner, the two clamping components 1 clamp the four corners of the flexible circuit board respectively, and then flatten it, the distance between the two clamping components 1 is set according to the length of the current punching device, the clamping component 1 comprises a fixing frame 11, a driving device 12, a first clamping mechanism 13, and a second clamping mechanism 14, the driving device 12 is fixedly connected to the fixing frame 11 and is parallel to the fixing frame 11, and the first clamping mechanism 13 is slidably connected to the fixing frame 11 One end of the fixed frame 11 is connected with the rotating shaft of the driving device 12 by a screw rod. A slide rail is provided on the inner side of the fixed frame 11. The first clamping mechanism 13 and the second clamping mechanism 14 are both slidably connected with the slide rail. The driving device 12 is a DC reduction motor. The number of rotations is determined by the power-on time, thereby driving the first clamping mechanism 13 to move a preset distance, thereby clamping and flattening the flexible circuit board. The second clamping mechanism 14 is slidably connected with the other end of the fixed frame 11 and forms a detachable connection with adjustable position to change the fixed position of the second clamping mechanism 14.
[0026] In this embodiment, the second clamping mechanism 14 is a fixed and adjustable clamping head, and the first clamping mechanism 13 is a movable clamping head. After the first clamping mechanism 13 and the second clamping mechanism 14 clamp the flexible circuit board, the first clamping mechanism 13 is driven by the driving device 12 to move backward to flatten the flexible circuit board. For a flexible circuit board with a smaller width, the fixed position of the second clamping mechanism 14 can be adjusted. When adjusting, the second clamping mechanism 14 is slid along the fixing frame 11 and then fixed. The second clamping mechanism 14 is adjusted to a position closer to the first clamping mechanism 13. In this way, when clamping and flattening the clamped flexible circuit board, the first clamping mechanism 13 does not need to travel a long distance to clamp, which saves clamping time for clamping and flattening a batch of flexible circuit boards with small widths.
[0027] In summary, the material clamping and leveling device can quickly clamp and level flexible circuit boards of different widths to improve processing efficiency.
[0028] In this embodiment, a first fixing position 111 and a second fixing position 112 are provided at one end of the fixing frame 11, and the first fixing position 111 and the second fixing position 112 are arranged in sequence in a horizontal direction, and the second fixing position 112 is located at the end of the fixing frame 11, and the second clamping mechanism 14 can form a detachable connection with the first fixing position 111 or the second fixing position 112; the length of the connection line between the first fixing position 111 and the second fixing position 112 is a, and the maximum clampable length of the clamping assembly 1 is b, 3a=b, that is, the second fixing position 112 is located at one-third of b. When the flexible circuit boards of different widths are clamped and flattened, if the If the width of the flexible circuit board is greater than two-thirds of b, the second clamping mechanism 14 needs to be adjusted and fixed on the first fixed position 111. At this time, the maximum distance between the first clamping mechanism 13 and the second clamping mechanism 14 is equal to b. If the width of the flexible circuit board is less than two-thirds of b, the second clamping mechanism 14 needs to be adjusted and fixed on the second fixed position 112. At this time, the maximum distance between the first clamping mechanism 13 and the second clamping mechanism 14 is equal to ba. For flexible circuit boards with smaller widths, after the second clamping mechanism 14 is fixed on the second fixed position 112, the stroke of the first clamping mechanism 13 is shorter and less time-consuming.
[0029] In this embodiment, both the first fixing position 111 and the second fixing position 112 are provided with fixing holes 101 for insertion and fixing. The fixing holes 101 provide a stationary insertion structure for the second clamping mechanism 14, so that workers can quickly adjust the position of the second clamping mechanism 14.
[0030] In this embodiment, a contact switch 113 is provided on the inner side of the fixing frame 11, and the contact switch 113 is located below the second fixing position 112. The contact switch 113 is electrically connected to an external controller. When the second clamping mechanism 14 is adjusted to the second fixing position 112, the contact switch 113 is triggered, and the external controller can receive the information sent back by the contact switch 113, thereby displaying the information that the second clamping mechanism 14 has been fixed on the second fixing position 112.
[0031] In this embodiment, the second clamping mechanism 14 includes a sliding frame 141, a longitudinal cylinder clamp 142, and an insertion fixing component 143.

At this time, the position adjustment of the second clamping mechanism 14 is completed; the structure of the first clamping mechanism 13 and the second clamping mechanism 14 is substantially the same, but the first clamping mechanism 13 does not have the insertion fixing component 143, and the sliding frame 141 of the first clamping mechanism 13 is also connected to the rotating shaft of the driving device 12 by a screw when being slidably connected to the fixed frame 11.

One end of the spring 1433 abuts against one end of the plug-in rod 1434, and the other end of the spring 1433 abuts against the side wall of the sleeve 1432. One end of the plug-in rod 1434 faces the fixing frame 11, and one end of the plug-in rod 1434 can be connected to the fixing frame 11. The first fixed position 111 or the second fixed position 112 forms a plug-in fixed connection; when the plug-in fixing component 143 is loosened, the plug-in rod 1434 is pulled in the opposite direction of the fixed frame 11, and the spring 1433 is squeezed and compressed to accumulate force. After the position of the sliding frame 141 is adjusted and aligned with the first fixed position 111 or the second fixed position 112, the plug-in rod 1434 is loosened, and the plug-in rod 1434 is extended and inserted toward the first fixed position 111 or the second fixed position 112 driven by the elastic force of the spring 1433, and the position fixation of the second clamping mechanism 14 is completed after insertion.
[0033] In this embodiment, a handle 14341 is provided at the other end of the plug rod 1434 , and the handle 14341 is away from the spring 1433 . The handle 14341 is convenient for a worker to pull the plug rod 1434 so as to loosen the plug fixing assembly 143 .
[0034] In this embodiment, the rotating shaft of the driving device 12 is provided with a screw rod 121, the screw rod 121 is parallel to the fixed frame 11, one end of the screw rod 121 is rotatably connected with one end of the fixed frame 11, and one side of the first clamping mechanism 13 is connected with the screw rod 121; when the first clamping mechanism 13 needs to clamp and flatten one end of the flexible circuit board, the driving device 12 rotates to drive the screw rod 121 to rotate, thereby driving the first clamping mechanism 13 to slide back and forth relative to the fixed frame 11.
