Description
Technical Field
[0001] The utility model belongs to the field of soft circuit boards, and in particular relates to a protective mechanism for processing soft circuit boards. Background Art
[0002] Flexible printed circuits, also known as flexible circuit boards or flexible printed circuit boards (FPCs), are a type of flexible printed circuit board (FPC) that, compared to conventional rigid resin printed circuit boards, offer advantages such as high wiring density, light weight, thinness, fewer wiring space restrictions, and greater flexibility. However, the soft nature of FPCs currently hinders flexible fastening and the required flexibility for easy and flexible removal and fastening during use. Furthermore, existing protective mechanisms used in FPC processing often have limitations, making it difficult to adjust them to the board's size. This introduces certain inconveniences during FPC processing and complicates operations. Utility Model Content
[0003] The purpose of the utility model is to provide a protective mechanism for processing soft circuit boards, which has the advantages of increasing the convenience of the operator in processing soft circuit boards, while improving the adaptability of the soft circuit boards to the use, and is suitable for the functions of the operator's processing.
[0004] The above technical objectives of the present invention are achieved through the following technical solutions: a protective mechanism for processing soft boards of circuit boards, comprising a base, the top of the base being respectively provided with a placement plate and a rear shell fixedly connected to each other, a moving block being provided at both ends of one side of the rear shell, a contact block being provided at the bottom of the moving block, a pull rod being fixedly installed on the top of the contact block and penetrating to the top of the moving block, a vertical shell being provided on one side of the moving block, a screw rod being rotatably connected to the interior of the vertical shell through a bearing, a screw rod being rotatably connected to the interior of the rear shell through a bearing, both ends of the surface of the screw rod being threadedly connected to a threaded block rod being fixedly connected to the vertical shell, a rod body rod being fixedly installed on the bottom of the placement plate and penetrating to the interior of the base, a worm gear being fixedly sleeved on the surface of the rod body rod, and a worm being meshed with the surface of the worm gear.
[0005] Using the above technical solution, when using a protective mechanism for a flexible circuit board, the position of the shift block is preferentially determined based on the thickness of the flexible board. The operator rotates knob 1, which in turn rotates screw rod 1. This rotation causes threaded block 1 to move longitudinally, which in turn drives the shift block and contact block longitudinally. Guide rod 1 coordinates with the movement of threaded block 1 to provide guidance. This arrangement facilitates adaptability to flexible circuit boards of varying thicknesses, increasing the flexibility of the protective mechanism. Furthermore, when processing the ends of the flexible circuit board, the operator can flexibly adjust the distance between the two contact blocks based on the length of the flexible circuit board, facilitating securement of the flexible circuit board. Rotating knob 2 rotates rod body 1, which in turn drives bevel gear 2 to rotate synchronously. The rotation of bevel gear 2 drives bevel gear 1 and screw rod 2 to rotate synchronously. Guide rod 2 coordinates with the movement of threaded block 2 to provide guidance. Screw rod 2 features opposing threads at both ends, enabling opposite movement of the two threaded blocks, thereby adjusting the position of the vertical housing, shift block, and contact block. The operator then pulls the pull ring and moves the pull rod. The spring contracts and expands in conjunction with the movement of the pull rod, placing the soft circuit board at the bottom of the contact block. After releasing the force on the pull ring, the spring expands, causing the contact block to squeeze and secure the soft circuit board. The operator then processes both ends of the soft circuit board. This arrangement increases the operator's convenience in processing the soft circuit board and improves the adaptability of the soft circuit board. Furthermore, during processing of the soft circuit board, the operator can adjust the angle of the soft circuit board. Turning knob three will drive the worm to rotate, which in turn drives the worm gear and rod body two to rotate. The bearings cooperate with rod body two to smoothly rotate inside the base. Rod body two simultaneously drives the placement plate and the back shell to adjust their angles, making the soft circuit board more suitable for the operator's processing and improving the operator's convenience in processing the soft circuit board.
[0006] The utility model is further configured such that a spring fixedly connected to the interior of the shift block is fixedly sleeved on the surface of the pull rod, and a pull ring is fixedly installed on the top of the pull rod.

[0009] With the above technical solution, the rotation of the knob 1 will drive the screw 1 to rotate, and the rotation of the screw 1 will cause the threaded block 1 to move longitudinally.
[0010] The utility model is further configured such that a bevel gear 1 is fixedly sleeved on the surface of the second screw, and a bevel gear 2 is meshed on the surface of the first bevel gear.
[0011] By adopting the above technical solution, the rotation of the bevel gear 2 will drive the bevel gear 1 and the screw 2 to rotate synchronously.
[0012] The present invention is further configured such that a rod body 1 penetrating to the top of the rear shell is fixedly sleeved inside the second bevel gear, and a knob 2 is fixedly mounted on the top of the first rod body.
[0013] With the above technical solution, the rotation of the second knob will drive the first rod to rotate, and the first rod will drive the second bevel gear to rotate synchronously.
[0014] The utility model is further configured such that the interior of the threaded block 1 is slidably sleeved with a guide rod 1 fixedly connected to the interior of the vertical shell, and the interior of the threaded block 2 is slidably sleeved with a guide rod 2 fixedly connected to the interior of the rear shell.

[0016] The utility model is further configured such that one end of the worm penetrates the surface of the base and is fixedly mounted with a knob three, and the rod body two and the base are rotatably connected to each other via a bearing.

[0019] The above technical solution is adopted: through the sliding connection between the slider and the circular groove, the rear shell is smoothly guided on the top of the base.
[0020] In summary, the present invention has the following beneficial effects:
[0021] 1.

The two ends of screw 2 14 are designed with opposite threads, which can achieve opposite movement of the two threaded blocks 2 15, thereby adjusting the position of vertical shell 9, shift block 4 and contact block 6. The operator then pulls pull ring 8 and drives pull rod 5 to move. Spring 7 contracts and expands in conjunction with the movement of pull rod 5.
