the limiting component comprises a limiting block, a limiting connecting rod and a limiting hole, the limiting hole is arranged on the top surface of the clamp body, the lower part of the limiting connecting rod is rotatably connected with the limiting hole, the upper part of the limiting connecting rod is connected with one end of the limiting block, the bottom surface of the limiting block is contacted with the top surface of the clamp body,
when the limiting block moves to the upper part of the profiling installation groove, the limiting block is tightly pressed on the top surface of the product to lock the product and prevent the product from moving up and down; when the limiting block leaves the profiling installation groove, the limiting block is separated from the product to unlock the product so as to carry out loading and unloading on the product.
In a preferred embodiment of the invention, the contour mounting groove and the reinforcing rib are matched to bear a product, so that the top surface of the product is flush with the top surface of the clamp body.
In a preferred embodiment of the present invention, the reinforcing rib is provided with a plurality of positioning holes.
In a preferred embodiment of the present invention, the limit connecting rod and the limit hole are in threaded connection.
In a preferred embodiment of the present invention, the clamp body is provided with an avoiding groove.
The invention has the beneficial effects that: the secondary furnace passing can be completed through the fixture under the condition that no plate edge exists after the PCBA cuts the plate, the repair rate is improved, and the production cost is reduced.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments are briefly introduced below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without inventive efforts, wherein:
fig. 1 is a schematic structural diagram of a repair reflow soldering fixture for a 5G communication product according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention includes:
the utility model provides a reprocess reflow soldering anchor clamps for 5G communication product, has cut the PCBA of board through the anchor clamps is fixed, uses the spacing PCBA that bears of anchor clamps, has realized that no flange limit PCBA accomplishes the secondary and has crossed reflow soldering and accomplish BGA and reprocess, and its structure includes: the fixture comprises a fixture body 1, a reinforcing rib 2, a profiling installation groove 3, a positioning hole 4, a positioning pin and a limiting assembly.
The profile modeling mounting groove set up in this is internal to the anchor clamps, the strengthening rib set up in the bottom of profile modeling mounting groove, when using, the PCBA board that does not have the flange limit is placed in the profile modeling mounting groove to by the bottom surface of strengthening rib bearing product, make the top surface of product and the top surface of anchor clamps body flush.
The locating hole set up in on the strengthening rib, the hole on the product is passed to the lower part of locating pin to can dismantle with the locating hole and be connected, further fix a position the product, place the product and produce the displacement in the course of working, improve accurate nature.
The limiting assembly comprises a limiting block 6, a limiting connecting rod 7 and a limiting hole, the limiting hole is formed in the top surface of the fixture body, the lower portion of the limiting connecting rod is rotatably connected with the limiting hole, the upper portion of the limiting connecting rod is connected with one end of the limiting block, the bottom surface of the limiting block is in contact with the top surface of the fixture body, and therefore the limiting block can compress a product in the profiling installation groove.
Wherein, the limiting connecting rod and the limiting hole can be in threaded connection.
When the limiting block moves to the upper part of the profiling installation groove, the limiting block is tightly pressed on the top surface of the product to lock the product and prevent the product from moving up and down; when the limiting block leaves the profiling installation groove, the limiting block is separated from the product to unlock the product so as to carry out loading and unloading on the product.
Through locating pin and stopper mode, fixed PCBA prevents that secondary backward flow PCB from being heated and producing the deformation and lead to the product to reprocess the unsuccessful product of causing and scrap.
