Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary devices for electronic industry, in particular to a pin braiding clamping device for tinning. Background Art
[0002] For high-reliability electronic products in the military, aerospace and other fields, in order to avoid "gold brittleness" and the resulting degradation of solder joint performance, it is clearly stated that gold-plated components must be tinned and gold-removed before soldering. Most of the pins are gold-plated on the surface, so the pins must be tinned and gold-removed before soldering. In the traditional small-batch tinning process, clips are used to clamp the pins waiting for tinning parts, and tinning is performed manually. This method is inefficient, the consistency is more dependent on manual labor, and the cost is high. Assembly line tinning is an automatic process that uses specific cycle fixtures to clamp-tin-remove pins. This method is more efficient, but the equipment cost is also high. Nitrogen atmosphere protection is required during the tinning process, and the cost of use is relatively high.
[0003] How to solve the above technical problems is the subject faced by the present utility model. Utility Model Content

It will not interfere with the braid during the matching process, and basically only fixes the braid when the matching is completed. It has a reasonable layout and a good clamping effect.
[0013] The specific characteristics of the utility model are that the outer sides of the roots of the two second clamping strips located on the outside are in an arc transition, and the third rubber cotton is outside the inner side of the arc transition and close to the arc transition, thereby ensuring the clamping effect of the end of the braided tape.

[0018] The specific features of the utility model are that the slider includes a first slider located at the end of the second clamping strip and a second slider located at the root of the second clamping strip, which saves materials, limits the two ends of the second clamping strip respectively, and has a reasonable layout.
[0019] The specific characteristics of the utility model are that the material of the first clamping unit is set to be wood with dense texture and smooth surface.

DETAILED DESCRIPTION
[0028] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method. Example
[0029] See also Figure 1 The embodiment of the utility model provides a pin braiding clamping device for tinning, comprising:
[0030] The first clamping unit 1 comprises a first clamping plate 11, a plurality of first clamping strips 12 arranged parallel to each other on one side of the first clamping plate 11, and a first spacer 13 left between adjacent first clamping strips 12;
[0031] The second clamping unit 2 includes a second clamping plate 21, a plurality of second clamping strips 22 arranged parallel to each other at one end of the second clamping plate 21 and corresponding to the plurality of first intervals 13, and a second interval 23 left between adjacent second clamping strips 22; the plurality of first clamping strips 12 located in the middle portion correspond to the plurality of second intervals 23 one by one;
[0032] And a plurality of collodions 3 are arranged between the first clamping unit 1 and the second clamping unit 2.
[0033] The first clamping strip 12 and the second clamping strip 22 are of equal length;
[0034] The second clamping strip 22 is slightly narrower than the corresponding first interval 13 ; the first clamping strip 12 is slightly narrower than the corresponding second interval 23 .
[0035] When in use, the end of the first clamping strip 12 and the end of the second clamping strip 22 are close to each other, and the middle part of the braid 41 of the pin braid 4 is pressed between the end of the first clamping strip 12 and the end of the second clamping strip 22, pushing the first clamping unit 1 and the second clamping unit 2, so that the first clamping strip 12 cooperates with the corresponding second interval 23, and the second clamping strip 22 cooperates with the corresponding first interval 23, similar to the insertion of fingers of both hands. During the process, the braid 41 slides in an S shape along the gap between the first clamping strip 12 and the second clamping strip 22, and is finally stored in the gap between the first clamping strip 12 and the second clamping strip 22. At the same time, the rubber cotton 3 fixes the braid 41, completing the clamping of the pin braid 4 and exposing the end of the pin that needs to be tinned evenly as a whole, see attached Figure 2 , and then the clamped pins 42 can be tinned as a whole. The structure and production are simple, the cost is low and it is easy to mass produce, the operation is convenient and the working efficiency is high. At the same time, after the matching is completed, the presence of the rubber cotton 3 can prevent the first clamping strip 12 and the second clamping strip 22 from sliding relative to each other, prevent the clamping failure, and ensure the smooth progress of subsequent operations.
[0036] The ends of the first clamping strip 12 and the ends of the second clamping strip 22 are both arc transitions, and the roots of two adjacent first clamping strips 12 and the roots of two adjacent second clamping strips 22 are both arc transitions, which facilitates the S-shaped sliding of the braid 41 and improves working efficiency.
[0037] The rubber cotton 3 includes a first rubber cotton 31 arranged between the roots of two adjacent first clamping strips 12, a second rubber cotton 32 arranged between the roots of two adjacent second clamping strips 22, and a third rubber cotton 33 arranged on the outer surface of the root of the second clamping strip 22 located on the outside. It will not cause interference to the braid 41 during the matching process, and basically only fixes the braid 41 when the matching is completed. The layout is reasonable and the clamping effect is good.
[0038] The roots of the two second clamping strips 22 on the outside are in an arc transition, and the third rubber cotton 33 is outside the inside of the arc transition and close to the arc transition, so as to ensure the clamping effect of the end of the braided tape 41.
[0039] The material of the first clamping unit 1 is set to be dense and smooth wood, which can be painted when necessary, or hard plastic, which is easy to obtain and low in cost, and at the same time ensures that its surface friction coefficient is small, which is convenient for clamping and matching.
[0040] The material of the collodion 3 is a foam sponge strip, which is easy to obtain and low in cost. At the same time, its surface friction coefficient is large, ensuring the fixing effect after clamping. Example
[0041] On the basis of Example 1, the rest is the same as Example 1, and the difference from Example 1 is that a slide groove 14 parallel to the first clamping strip 12 is provided on the first clamping plate 11, and the slide groove 14 extends to the end surface of the first clamping plate 11 away from the root of the first clamping strip 12;
[0042] The second clamping strip 22 is provided with a sliding block matching the sliding groove 14 .
[0043] This further prevents the first clamping unit 1 from sliding along the normal direction of the first clamping plate 11 after the first clamping unit 1 cooperates with the second clamping unit 2, thereby further ensuring that subsequent operations proceed smoothly.
[0044] The slide groove 14 is located at any first interval 13 and is located on the same side of the first clamping plate 11 as the first clamping strip 12; correspondingly, the slider is located on the bottom surface of the second clamping strip 22, see the attached Figure 4 , 5 , the layout is reasonable to prevent interference when the braid 41 slides.
[0045] The slider includes a first slider 24 located at the end of the second clamping strip 22 and a second slider 25 located at the root of the second clamping strip 22, which saves materials, limits the two ends of the second clamping strip 22 respectively, and has a reasonable layout.
[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
