Description

Technical Field

[0001] This application relates to the field of wire feeding devices, and in particular to a wire feeding device for a gold ribbon cutter. Background Technology

[0002] As microwave components continue to upgrade towards lighter weight and smaller size, higher requirements are placed on the utilization of internal space in the system. To save space, gold strips or gold wires are increasingly used for electrical interconnection inside the components, and the arrangement of components is becoming more compact and concentrated. The gold strips need to be cut to size before use.

[0003] A Chinese patent with authorization announcement number CN212665044U discloses a gold strip equidistant shearer, including a base, a rotatable wire feeding coil, a rotatable roller assembly, a rocker arm, and a blade. The roller assembly includes two parallel upper and lower rollers with their rolling surfaces in contact. A limiting hole is provided in the base for the gold strip to pass through. One end of the gold strip is wound around the wire feeding coil, and the other end passes through the space between the upper and lower rollers and then out through the limiting hole. The blade is fixed on the rocker arm, and the cutting edge of the blade rests against the outer end face of the limiting hole. One end of the rocker arm is hinged to the base, and the other end is suspended. The hinged end of the rocker arm is connected to the roller assembly through a linkage mechanism and a ratchet mechanism. When the rocker arm is turned, the rocker arm drives the roller assembly to roll, thereby conveying the gold strip and driving the blade to perform cyclic equidistant shearing of the gold strip.

[0004] In the aforementioned gold strip equidistant shearing device, during the feeding process, the upper and lower rollers pull the gold strip on the feeding coil through friction with the gold strip as they roll. The limiting hole on the base is located near the middle of the feeding coil. During the feeding process, the gold strip on the feeding coil gradually changes its exit angle and tension direction, which can easily cause the gold strip to twist. The twisted gold strip enters the roller group and is forcibly flattened, which can produce micro-creases or even stress concentration, directly affecting the subsequent bonding strength and microwave performance.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0022] This application discloses a wire feeding device for a gold strip cutter.

[0023] Example 1 A wire feeding device for a gold strip cutter is used to supply wire to the wire pulling device 6 of the gold strip cutter. The wire feeding device for the gold strip cutter includes a base plate 1, a wire feeding main wheel 2, and a wire feeding support wheel 3. The base plate 1 is fixedly installed in a predetermined position. The wire feeding main wheel 2 is set at different predetermined positions on the top of the base plate 1 through a bracket 21. The wire feeding support wheel 3 is coaxially set on the wire feeding main wheel 2, and multiple support wheels 3 are provided along the wire feeding main wheel 2. The wire feeding support wheel 3 slides with the wire feeding main wheel 2 along the axial direction of the wire feeding main wheel 2.

[0024] The gold strip to be cut is wound on the pay-off roller 3. During wire feeding, the position of the pay-off main roller 2 on the base plate 1 is adjusted according to the wire routing position of the gold strip on the wire pulling device 6 of the gold strip cutter. This brings the pay-off roller 3 closer to the wire routing position of the gold strip on the wire pulling device 6, reducing the possibility of twisting or deformation of the gold strip during the pay-off process. Simultaneously, the wire pulling device 6 pulls the pay-off roller 3 to rotate, and simultaneously pulls it to slide along the axis of the pay-off main roller 2. This fine-tunes the position between the gold strip to be cut on the pay-off roller 3 and the wire pulling device 6, further aligning the gold strip and the wire pulling device 6 and reducing the possibility of twisting during the wire pulling process. After the current pay-off roller 3 has finished paying, the pay-off main roller 2 is moved again to bring a new pay-off roller 3 closer to the wire pulling device 6. After all the pay-off rollers 3 on the current pay-off main roller 2 have finished paying, the pay-off rollers 3 are replaced uniformly.

[0025] The top of the base plate 1 is provided with a groove 11 along the axis of the main wire feeding wheel 2. The bracket 21 is partially placed inside the groove 11 and slides along the length of the groove 11. A locking member 4 for fixing the bracket 21 is provided between the base plate 1 and the bracket 21.

[0026] When adjusting the relative position of the main feed roller 2 and the base plate 1, the operator manually slides the bracket 21 inside the slide groove 11 to adjust the position of the feed roller 3 over a wide range. After the feed roller 3 approaches the wire pulling device 6, the main feed roller 2 is locked onto the base plate 1 by the locking piece 4 to reduce the possibility of the main feed roller 2 moving again, thereby improving the position accuracy of the feed roller 3 that is feeding wire.

[0027] A locking groove 12 is provided on the side wall of the slide 11 along the length direction of the slide 11. The bracket 21 includes a slide plate 211 and a support plate 212. The slide plate 211 and the support plate 212 are integrally formed. The slide plate 211 is partially placed in the locking groove 12 and slides in cooperation with the locking groove 12 along the length direction of the locking groove 12. The support plate 212 supports the wire feeding main wheel 2 and rotates in cooperation with the wire feeding main wheel 2.

[0028] When the slide plate 211 slides inside the locking groove 12, the inner wall of the locking groove 12 limits the slide plate 211, further reducing the possibility of the bracket 21 flipping over.

[0029] The inner wall of the locking groove 12 is provided with a locking hole 13 that penetrates the top of the base plate 1. The locking component 4 includes a locking rod, which is threadedly connected to the locking hole 13. The bottom end of the locking rod is used to press the slide plate 211 against the inner wall of the locking groove 12.

[0030] When fixing the bracket 21 to the base plate 1, rotate the locking rod to press the sliding plate 211 against the inner wall of the locking groove 12. When it is necessary to move the bracket 21, simply loosen the locking rod.

[0031] The main feed roller 2 is provided with multiple blocking elements 5 along its own length. Two adjacent blocking elements 5 form the moving area on a single feed roller 3. By limiting the feed roller 3 with two adjacent blocking elements 5, the moving area of ​​the feed roller 3 along the axis of the main feed roller 2 is controlled.

[0032] The outer wall of the main wire feeding roller 2 is provided with multiple annular blocking grooves 22 coaxially along its length. The blocking component 5 includes a retaining spring, which engages with the blocking groove 22. The retaining spring is engaged with the blocking groove 22 according to the width of the wire feeding support roller 3, thereby improving the convenience and accuracy of setting the size of the moving area of ​​the wire feeding support roller 3.

[0033] The implementation principle of the wire feeding device for a gold strip cutter in Embodiment 1 of this application is as follows: According to the wire feeding position of the gold strip to be cut on the wire pulling device 6, the bracket 21 is manually slidable to move the wire feeding main wheel 2 in the groove 11 of the base plate 1, so that the wire feeding support wheel 3 of the gold strip is close to the wire feeding position. The locking rod is tightened to fix the bracket 21. The wire pulling device 6 pulls the wire feeding support wheel 3 to rotate and slide slightly along the axis of the wire feeding main wheel 2, so that the gold strip is precisely aligned with the wire pulling device 6. After the current wire feeding support wheel 3 finishes feeding, the wire feeding main wheel 2 is moved again to put the new wire feeding support wheel 3 into place, until all wire feeding support wheels 3 have finished feeding and are replaced uniformly.

[0034] Example 2 The difference between Embodiment 2 and Embodiment 1 is that the top of the base plate 1 has multiple placement slots 14 along the axis of the main wire feeding wheel 2, and the bracket 21 is inserted into the placement slots 14. The side wall of the placement slot 14 along the axis of the main wire feeding wheel 2 has an inverted T-shaped limiting slot 15, and the bracket 21 is inserted into the limiting slot 15. In order to further improve stability, the base plate 1 is also provided with a locking rod, which presses the bracket 21 tightly.

[0035] The implementation principle of Example 2 is as follows: According to the position where the wire feeding support roller 3 needs to be placed, the worker inserts the bracket 21 into the adjacent placement slot 14. At this time, the placement slot 14 acts as a scale mark, which makes it easy for the worker to quickly place the bracket 21 near the predetermined position. Then, the bracket 21 is finely adjusted and moved in the placement slot 14 so that the bracket 21 is placed in the limiting slot 15, thereby further improving the convenience of adjusting the position of the wire feeding support roller 3.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
