Description

Technical Field

[0001] The utility model relates to the technical field of laser resistance trimming machine preparation, in particular to a locking fixture for a ceramic circuit substrate. Background Art

[0002] The laser resistor trimming machine uses an extremely fine laser beam to hit thick and thin film resistors, and realizes the cutting of thick and thin film circuits by vaporizing and evaporating the resistor body, such as a laser resistor trimming machine disclosed in Chinese patent announcement number CN220856243U. The laser beam cuts thick and thin film resistors according to a computer-preset program, and changes the resistance value of the resistor by changing the geometric shape of the thick and thin film resistors. During the laser resistor trimming process of the ceramic circuit substrate by the laser resistor trimming machine, the ceramic circuit substrate needs to be locked and fixed. However, since the laser resistor trimming machine needs to frequently replace the ceramic circuit substrate, the current locking fixture of the laser resistor trimming machine can only be used for one size of ceramic circuit substrate. When different sizes of ceramic circuit substrates are needed, different locking fixtures need to be replaced accordingly. Therefore, each time the ceramic circuit substrate is replaced, the corresponding locking fixture needs to be replaced, which increases the operating intensity.

[0034] The technical solution of the utility model is further described in conjunction with the following embodiments.

[0035] Example 1

The pneumatic clamping arms 300 can be movably embedded in the plate body 200, and the fixed clamping arms 400 are fixedly embedded in the plate body 200. One pneumatic clamping arm 300 and one fixed clamping arm 400 are arranged opposite to each other, the pneumatic clamping arm 300 and the other pneumatic clamping arm 300 are perpendicular to each other, and the fixed clamping arm 400 and the other fixed clamping arm 400 are perpendicular to each other. A locking clamp 100 can be detachably assembled on one fixed clamping arm 400 or one pneumatic clamping arm 300.

[0037] The fixed clamp arm 400 is provided with a plurality of first assembly holes 410 for detachable assembly of the locking clamp 100 .

[0038] The pneumatic clamp arm 300 is provided with an air inlet pipe 310, a pneumatic slide pipe 320 and an assembly plate 330. The pneumatic slide pipe 320 can be slidably mounted on the outer surface of the air inlet pipe 310, and the assembly plate 330 is fixedly assembled on the upper surface of the pneumatic slide pipe 320; the assembly plate 330 is provided with a plurality of second assembly holes 340 for detachable assembly of the locking chuck 100, such as Figure 2 .

[0039] It should be noted that the fixed clamp arm 400 of the utility model can be set to adjust the fixed position of the locking clamp 100 in the fixed clamp arm 400 through different first assembly holes 410, and the pneumatic clamp arm 300 can be set to adjust the fixed position of the locking clamp 100 in the pneumatic clamp arm 300 through different second assembly holes 340, so as to fix ceramic circuit substrates of different sizes. In addition, the utility model clamps the ceramic circuit substrate through the pneumatic clamp arm 300, and since the pneumatic clamp arm 300 is more flexible than the current mechanical clamp arm, it will not cause damage to the ceramic circuit substrate. A return spring is arranged inside the pneumatic slide tube 320, and the two ends of the return spring are respectively fixed to the inner wall of the pneumatic slide tube 320 and the air inlet pipe 310.

[0040] The locking chuck 100 is provided with a base 110, an abutment member 120 for abutting against a ceramic circuit substrate, and an elastic connection assembly 130. The base 110 and the fixed clamp arm 400 or the pneumatic clamp arm 300 are detachably assembled, and the abutment member 120 is movably assembled on the upper surface of the base 110 through the elastic connection assembly 130. Figure 3 .

[0041] The base 110 is provided with a third assembly hole 111 and a fourth assembly hole 112 . The third assembly hole 111 is detachably assembled with the fixed clamp arm 400 or the pneumatic clamp arm 300 . The third assembly hole 111 is elastically connected to the fourth assembly hole 112 .

[0042] The elastic connection assembly 130 is provided with a connecting rod 131, a pair of transverse tension springs 132 and a pair of vertical tension springs 133. The connecting rod 131 is located inside the abutment 120 and inside the fourth assembly hole 112.

[0043] It should be noted that the elastic connection assembly 130 of the utility model is used to improve the buffering degree of the locking clamp 100. When the locking clamp 100 is clamped with the ceramic circuit substrate, the abutment member 120 will move backward to prevent the locking clamp 100 from damaging the ceramic circuit substrate when it contacts the ceramic circuit substrate. The utility model clamps the ceramic circuit substrate by stretching the horizontal pull spring 132 in two opposite directions.

[0044] The base 110 is provided with a sliding groove 113 for the abutment member 120 to move, and one end of the abutment member 120 is located inside the sliding groove 113 .

[0045] The locking clamp can fix ceramic circuit substrates of different sizes by cooperating with the pneumatic clamp arm 300 and the fixed clamp arm 400. In addition, the utility model clamps the ceramic circuit substrate through the pneumatic clamp arm 300. Since the pneumatic clamp arm 300 is more flexible than the current mechanical clamp arm, it will not cause damage to the ceramic circuit substrate.

[0046] Example 2

Figure 7 and Figure 8 .

[0048] The upper plate 210 is provided with a second fixing hole 211 for fixing the relative positions of the upper plate 210 and the lower plate 220 . The first fixing hole 221 and the second fixing hole 211 respectively fix the member 230 so that it can be detachably assembled.

[0049] It should be noted that the upper plate 210 of the present invention can rotate relative to the lower plate 220 . When adjusting the current angle, the upper plate 210 can be fixed by using the fixing member 230 to pass through the first fixing hole 221 and the corresponding second fixing hole 211 .

[0050] Similar to the first embodiment, the pneumatic clamp arm 300 and the fixed clamp arm 400 can be rotated in this embodiment, thereby improving the flexibility of the clamping angle of the locking clamp.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model.
