Technical Field
[0001] The utility model relates to the technical field of jigs, in particular to a capacitive pen assembly jig. Background Art
[0002] The capacitive pen includes a pen cap, a pen tube and a pen nib, wherein the pen cap, the pen tube and the pen nib are produced in sections by the manufacturer and subsequently assembled using an assembly jig.
[0003] During the production process, the processing machine has errors in processing accuracy, resulting in the problem of different radial dimensions and specifications of the mass-produced pen tubes. The limiting grooves that the assembly jig can accommodate and roughly position the pen tubes adopt a groove structure with a square cross-section shape. The size of the limiting groove is constant and can only be applied to pen tubes of one specification. In the rough positioning scheme of the pen tube of the capacitive pen, firstly, when the cross-sectional area of the pen tube is larger than the cross-sectional area of the limiting groove, there is a problem that the pen tube cannot be put in; secondly, when the cross-sectional area of the pen tube is smaller than the cross-sectional area of the limiting groove, there is a problem that the pen tube cannot be transferred into the limiting groove and cannot be completely clamped by the limiting groove. The above two situations where the pen tube and the limiting groove are not compatible also further cause the pen tube to be easily displaced relative to the limiting groove. Then, when one end of the pen tube is pressurized and bonded with the pen cap, the pen tube and the pen cap cannot maintain ideal coaxiality, and a large step difference is likely to occur between the two, which greatly affects the holding experience of the finished capacitive pen.
[0004] In summary, in the related art, when a set of assembly jigs is used to assemble capacitive pens of different specifications, the coaxiality of the pen cap and the pen tube is likely to be low. Utility Model Content

[0036] The capacitive pen assembly fixture proposed in the utility model is as follows: Figures 1 to 3 As shown, including:
[0037] Fixture base 10;
[0038] A pressure-maintaining bottom block 20 is disposed on the fixture base 10; the pressure-maintaining bottom block 20 is provided with at least one limiting groove capable of accommodating a portion of the structure of the pen cap 999 and a portion of the structure of the pen tube 998, and supporting inclined surfaces are formed on opposite side walls of each limiting groove 20A, respectively, and the supporting inclined surfaces are extended along the length direction of the limiting groove 20A; and
[0039] A pressure-maintaining top block 30, the pressure-maintaining top block 30 is movably connected to the pressure-maintaining bottom block 20, and a flexible pad 301 is provided on one side of the pressure-maintaining top block 30 facing the pressure-maintaining bottom block 20;
[0040] The capacitive pen assembly jig has an assembly state in which the pen cap 999 and the pen tube 998 are accommodated side by side in the limiting groove 20A; in the assembly state, the flexible pad 301 cooperates with the two supporting surfaces to clamp and fix the pen cap 999 and the pen tube 998 so that the pen cap 999 and the pen tube 998 are coaxially arranged in the limiting groove.
[0041] In the technical solution of the utility model, the capacitor pen assembly jig includes a jig base 10, a pressure-maintaining bottom block 20 and a pressure-maintaining top block 30. In order to realize that a set of assembly jigs can assemble capacitor pens of various specifications, the limiting groove 20A of the pressure-maintaining bottom block 20 has two supporting inclined surfaces, each supporting upper surface supports one surface of the capacitor pen, and then the pressure-maintaining top block 30 moves toward the pressure-maintaining bottom block 20 so that the flexible pad 301 of the pressure-maintaining top block 30 abuts against the capacitor pen and undergoes deformation to match the shape of the capacitor pen. At this time, the pen cap 999 and the pen mouth 997 of the capacitor pen are subjected to the force from the supporting inclined surfaces and the flexible pad 301 in the upper and lower positions to correct the coaxiality between the pen cap 999 and the pen mouth 997 of the capacitor pen. At the same time, the pen cap 999 and the pen mouth 997 will not roll in the limiting groove 20A under the restriction of the two supporting inclined surfaces and the flexible pad 301, so as to meet the assembly requirements, reduce the step difference between the pen cap 999 and the pen tube 998, and improve the assembly accuracy.
[0042] In the present embodiment, the fixture base 10 is composed of a metal plate, and a pressure-maintaining bottom block 20 is provided on its surface. The pressure-maintaining bottom block 20 can be detachably connected by fasteners such as bolts, or can be integrated with the fixture base 10 through a casting process, etc., which is not limited here. At least one limiting groove 20A is provided on the side of the pressure-maintaining bottom block 20 facing away from the fixture base 10. The cross-sectional shape of the limiting groove 20A can be V-shaped or not. It is only necessary to form the two inner side surfaces of the limiting groove 20A at a certain angle to form two supporting inclined surfaces. When the capacitive pen is placed in the limiting groove 20A, the supporting inclined surface can abut against the two side surfaces of the pen cap 999 and the pen tube 998. Furthermore, a portion movable relative to the pressure-maintaining bottom block 20 is provided above the pressure-maintaining bottom block 20. The pressure-maintaining top block 30 can be moved by setting a guide rod structure that penetrates the pressure-maintaining bottom block 20 and the pressure-maintaining top block 30, or by setting a guide rail structure on the same side of the pressure-maintaining bottom block 20 and the pressure-maintaining top block 30. No limitation is made here. A flexible pad 301 is provided on the side of the pressure-maintaining top block 30 facing the pressure-maintaining bottom block 20. The flexible pad 301 is bonded to the pressure-maintaining top block 30 to prevent it from falling. When the capacitive pen needs to be assembled, the capacitive pen assembly fixture enters an assembly state. In the assembly state, the flexible pad 301 cooperates with the two supporting surfaces to clamp and fix the pen cap 999 and the pen tube 998, so that the pen cap 999 and the pen tube 998 are coaxially arranged in the limiting through groove 20A. The pen tube 998 and the pen cap 999 are ensured to be coaxial under the joint action of the flexible pad 301 and the two supporting inclined surfaces.
[0043] In an embodiment of the present invention, the two supporting inclined surfaces are symmetrically arranged.
[0044] In this embodiment, the supporting inclined surfaces are symmetrically arranged so that the pen cap 999 and the pen tube 998 will not tilt in a certain direction when placed in the limiting groove 20A, and when the flexible pad 301 is tightly against the pen cap 999 and the pen tube 998, the pen cap 999 and / or the pen tube 998 will not roll.
[0045] In one embodiment of the present invention, Figures 1 to 3 As shown, the capacitive pen assembly jig also includes a pressing adjustment component, which includes a pressing adjustment rod 41 and a rotating handshake 42; the pressing adjustment rod 41 is fixed to the jig base 10, and the pressing adjustment rod 41 passes through the pressure-maintaining bottom block 20 and the pressure-maintaining top block 30; the rotating handshake 42 is arranged on the side of the pressure-maintaining top block 30 facing away from the pressure-maintaining bottom block 20, and the rotating handshake 42 is rotatably connected to the pressing adjustment rod 41.
[0046] In this embodiment, the capacitive pen assembly jig also includes a pressing adjustment component, which includes a pressing adjustment rod 41 and a rotating handshake 42. One end of the pressing adjustment rod 41 is a hexagonal nut end. A contoured groove that can accommodate the hexagonal nut is provided at the bottom of the jig base 10, so that the hexagonal nut end of the pressing adjustment rod 41 can be stably inserted into the jig base 10. Then spot welding or adhesive can be used to ensure that the pressing adjustment rod 41 is fixed. The main rod of the pressing adjustment rod 41 is penetrated by a pressure-maintaining bottom block 20 and a pressure-maintaining top block 30. A rotating handshake 42 is sleeved on the end of the pressing adjustment rod 41. The rotating handshake 42 is screwed onto the pressing adjustment rod 41. The rotating handshake 42 has two gripping parts, which are arranged relatively to each other so that the rotating handshake 42 can be rotated to adjust the distance between the pressure-maintaining top block 30 and the pressure-maintaining bottom block 20, thereby changing the deformation of the flexible pad 301 after abutting the pen cap 999 and the pen tube 998. It can be understood that under the adjustment of the rotating handshake 42 and the pressing adjustment rod 41, the downward stroke of the pressure-maintaining top block 30 can be judged based on the operator's naked eye observation, so as to know whether the flexible pad 301 abuts against the pen cap 999 and the pen tube 998.
[0047] In one embodiment of the present invention, Figures 1 to 3 As shown, each pressure-maintaining bottom block 20 includes a first limiting segment 201 and a second limiting segment 202, and the first limiting segment 201 and the second limiting segment 202 are spaced apart to form a pressure-maintaining gap 20B; the first limiting segment 201 and the second limiting segment 202 both have a limiting through groove 20A, and the pressure-maintaining gap 20B is connected to the limiting through groove 20A.
[0048] In this embodiment, each pressure-maintaining bottom block 20 includes a first limiting section 201 and a second limiting section 202. The first limiting section 201 and the second limiting section 202 are spaced apart to form a pressure-maintaining gap 20B. The first limiting section 201 and the second limiting section 202 both have a limiting through groove 20A. The pressure-maintaining gap 20B is connected to the limiting through groove 20A. After the capacitive pen is placed in the limiting through groove 20A, the first limiting section 201 accommodates part of the structure of the pen cap, and the second limiting section 202 accommodates part of the structure of the pen tube. At least part of the structure connecting the pen cap 999 and the pen tube 998 will be located in and block the pressure-maintaining gap 20B there. At the same time, the pressing adjustment rod 41 is inserted in the pressure-maintaining gap 20B.

When the push rod handle 61 is pressed down, the push rod 62 is driven by the connecting arc piece 63. The push rod 62 moves forward so that it can abut the pen cap 999. At the same time, the pen mouth 997 is limited by the pen mouth 997 limit block 50. At this time, the pen cap 999 and the pen tube 998 are subjected to axial force to make the pen cap 999 and the pen tube 998 in close contact. After the push rod handle 61 is pressed into place, the rotating handshake 42 is rotated to lock the pressure-maintaining bottom block 20 and the pressure-maintaining top block 30 to ensure the coaxial alignment between the pen cap 999 and the pen tube 998.
