Description

Keyboard compresses tightly tool

The utility model discloses a patent application number is 2019203892850, application date is 2019 3 month 26 days, the patent name is a keyboard button draws branch case application of detection device's utility model patent.

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of the button detects, especially, relate to a keyboard compresses tightly tool.

[ background of the invention ]

The keyboard is generally assembled by an aluminum substrate, a circuit board, a scissors support frame and a key cap, and the currently known main reasons for causing the poor elasticity or pulling force of the key cap of the keyboard are as follows: 1) the materials are not good, for example, the clamping hooks of the aluminum base plate deform, the middle shaft of the scissors supporting frame is broken, or the key cap structure assembled by the inner scissors and the outer scissors lacks materials and collapses, and the four corners of the key cap and the assembled part of the inner scissors and the outer scissors (namely, the written name is the structure of the water drop hole and the chute) are not good; 2) poor assembly, such as damage to the keyboard or keycap structure during assembly due to human or assembled mechanical device failure. The key cap elasticity or the drawing force of the keyboard is insufficient or has no elasticity due to the two points, and the service life and the mechanical hand feeling of the keyboard can be seriously influenced after the keyboard is made into a finished product. Therefore, after the key cap is mounted on the keyboard, in order to ensure the reliability of subsequent use, the drawing force of the keyboard key cap after being assembled needs to be tested.

When drawing the test to the keyboard key cap, it is very critical to compress tightly on keyboard surface, if the keyboard surface does not obtain effectual suppression, then when the key cap is pulled up or jack-up, the keyboard surface can be along with the one end distance of pulling out the piece or going up the mechanism and come up together, the influence draws the test result.

Therefore, the utility model discloses a new keyboard compresses tightly tool and solves above-mentioned problem.

[ Utility model ] content

The utility model discloses a main aim at provides a keyboard compresses tightly tool can effectually compress tightly, flatten the keyboard surface, and the reliability of test result is drawn to the guarantee key cap.

The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a keyboard compresses tightly tool, its is for covering a clamp plate on the keyboard surface, be provided with the bar that corresponds with the gap between two adjacent lines of key caps on the clamp plate and lead to the groove, adjacent two form a support strip between the groove is led to the bar, the lower surface of support strip is provided with a plurality of compact heap that insert in the gap between two adjacent key caps and compress tightly the keyboard surface.

Further, the key cap drawing block is inserted into the strip-shaped through groove to draw the key cap.

Compared with the prior art, the utility model relates to a keyboard compresses tightly tool's beneficial effect lies in: can effectually compress tightly, flatten the keyboard surface, ensure that the key cap draws the reliability of test result.

[ detailed description ] embodiments

Example (b):

referring to fig. 1 to 4, the present embodiment is a keyboard pressing fixture 100, which includes a supporting frame 1 capable of moving along a long side direction of a keyboard, a plurality of key cap drawing modules 2 fixed on the supporting frame 1, and a pressing member 3 for pressing the keyboard, where the key cap drawing modules 2 include a first driving member 21, an elastic pressure sensor 22 driven by the first driving member 21 to move up and down, and a drawing block 23 disposed at a sensing end of the elastic pressure sensor 22.

The support frame 1 is arranged at the movable end of a linear transfer mechanism, the linear transfer mechanism drives the key to move along the long edge direction of the keyboard, in the process, the key caps can be pulled and tested by driving the pull block 23 to move up and down through the first driving piece 21, and different heights of the key caps can be set according to different pull strokes.

The keycap drawing module 2 further comprises a second driving part 24 and a first connecting plate 25 driven by the second driving part 24 to perform horizontal linear motion, and the first driving part 21 is fixedly arranged on the first connecting plate 25. In this embodiment, the second driving member 24 can move the pulling block 23 between keycaps in different rows.

Elastic pressure sensor 22 forms one with drawing piece 23 and draws test module, and in order to improve detection efficiency, in this embodiment, the expansion end of first driving piece 21 is provided with second connecting plate 26, is provided with two on the second connecting plate 26 draw test module, adjust two draw the adjustment mechanism 27 of distance between the test module, adjustment mechanism 27 can adopt the screw rod structure to realize the position fine setting. Two pulling blocks 23 in the two pulling test modules respectively correspond to the same keycap in the two keyboards.

The pressing piece 3 is a pressing plate covering the surface of the keyboard, the pressing piece 3 is provided with strip-shaped through grooves 31 corresponding to gaps between two adjacent rows of keycaps, a supporting strip 32 is formed between every two adjacent strip-shaped through grooves 31, and the lower surface of the supporting strip 32 is provided with a plurality of pressing blocks 33 inserted into the gaps between every two adjacent keycaps to press the surface of the keyboard.

The pulling block 23 is inserted into the strip-shaped through groove 31 to pull the keycap. The end of the pulling block 23 is provided with a hook 231 for hooking the key cap.

In this embodiment, the key cap is drawn module 2 and is provided with threely, each key cap is drawn and is provided with two in module 2 and draws test module, detect two keyboards simultaneously, in every keyboard, again detect wherein three key cap simultaneously, once along the long limit walking of keyboard, then accomplish the detection of triplex row key cap, then once along with support frame 1 along the long limit direction of keyboard return, second driving piece 24 drive is drawn test module and is switched to the key cap position of adjacent one line, detect other triplex row key cap. Therefore, the support frame 1 is moved back and forth along the long edge direction of the keyboard once, so that the drawing test of all keycaps on the two keyboards can be completed, and the test efficiency is greatly improved; meanwhile, one key cap is tested by one drawing block, and the moving drive of the drawing block on the Z axis is independently arranged, so that different drawing heights can be set according to different key caps, and the test requirements of various key caps are met; set up the clamp plate alone and compress tightly the keyboard, alleviateed the holistic weight of test module, alleviateed the load of driving piece, improved life.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
