Description

Technical Field

[0001] This utility model relates to the field of SMT surface mount technology (SMT) processing, and in particular to a SMT manual connector mounting fixture. Background Technology

[0002] With the changing times and continuous technological advancements, the application fields of circuit boards are becoming increasingly widespread. The demand for medical flexible circuit boards is growing daily. Medical products have extremely high stability requirements, and their circuits are typically very precise. During SMT (Surface Mount Technology) assembly, installing connectors is very difficult and hard to automate. Manual connector installation is also very risky, as manual alignment can lead to significant deviations and inaccurate hole alignment. This can easily cause the pads around the mounting holes on the flexible circuit board to bulge, resulting in wire breakage or micro-fractures, causing considerable trouble for customers and seriously affecting the reliability of their products. Furthermore, these issues can lead to short circuits, fires, and other problems during product use, potentially causing medical accidents. These problems have been a persistent concern for us, severely impacting production progress and yield rates, and posing significant quality risks to our customers. Utility Model Content

Therefore, it should not be construed as a limitation of this utility model.

[0021] In the description of this utility model, if there is a description of quantity, "several" means one or more, "more than" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] like Figures 1 to 5As shown, this utility model discloses an SMT manual connector mounting fixture, including a base plate 1, a stripper plate 2, and a clamping plate 3. The stripper plate 2 is mounted on the upper end of the base plate 1, and the clamping plate 3 is mounted on the upper end of the stripper plate 2. The clamping plate 3 has a product fixing area in the middle, and the product fixing area is arrayed with multiple slots 31 for accommodating flexible circuit boards 4. The clamping plate 3 has a clamping fixture positioning hole 32 at each of the four corners of the product fixing area. The stripper plate 2 has a product carrying area in the middle corresponding to the position of the product fixing area. The product carrying area has multiple support through holes 21 corresponding to the positions of the connector pin holes 41 on the flexible circuit board 4 at positions corresponding to the positions of the slots 31. The stripper plate 2 has a product carrying area in the middle corresponding to the position of the product carrying area. The base plate 1 is provided with four unloading plate fixture positioning holes 22, each corresponding to one of the four positioning holes 32 of the card plate fixture. The middle part of the base plate 1 is provided with a product corresponding area, which corresponds to the product carrying area. The product corresponding area is provided with multiple pin through holes 11 corresponding to the positions of the support through holes 21 at the positions of each card slot 31. The base plate 1 is provided with four base plate fixture positioning holes 12, each adapted to one of the four positioning holes 22 of the unloading plate fixture, located around the product corresponding area. Positioning pins are provided in the base plate fixture positioning holes 12. The card plate 3 is provided with multiple directional holes 13, 23, and 33 located around the product fixing area, the unloading plate 2 is provided with multiple directional holes 13, 23, and 33 located around the product carrying area, and the base plate 1 is provided with multiple directional holes 13, 23, and 33 located around the product corresponding area.

[0024] In use, first install a positioning pin in each of the four positioning holes 12 on the base plate 1. Then, install the unloading plate 2 on the upper end of the base plate 1 according to the positions of the orientation holes 13 and 23, and fit the positioning pins in the four positioning holes 22 of the unloading plate fixture. Next, install the clamping plate 3 on the upper end of the unloading plate 2 according to the positions of the orientation holes 23 and 33, and fit the positioning pins in the four clamping plate fixture positioning holes 32. Then, place the flexible circuit board 4 into the slot 31 on the clamping plate 3. Finally, insert the connector pin 6 into the machine pin socket 41 of the flexible circuit board 4. At this time, since the lower end is provided with a support through hole 21 and a pin through hole 11, it can provide support for the outer periphery of the machine pin socket 41 of the flexible circuit board 4, preventing the ring pads around the machine pin socket 41 of the flexible circuit board 4 from bulging out when manually inserting the connector 5, thus avoiding the wires being broken. This makes the insertion of the connector 5 simpler and improves the product qualification rate.

[0025] After connector 5 is inserted, the corresponding soldering is performed in subsequent processes.

[0026] In this invention, the diameter of the support via 21 and the diameter of the pin via 11 are both 0.05 mm larger than the connector pin insertion hole 41 on the flexible circuit board 4, so as to provide support for the periphery of the hole without affecting the insertion of the connector pin 6.

[0027] In this invention, the positioning holes 22 of the unloading plate fixture and 32 of the clamping plate fixture are both 0.025mm larger than the positioning hole 12 of the bottom plate fixture, which facilitates the insertion and release of the unloading plate 2 and the clamping plate 3 into and out of the positioning pin.

[0028] In this invention, the unloading plate 2 is 5-10mm larger on one side than the base plate 1, making it easier to hold the unloading plate 2.

[0029] In this utility model, the base plate 1 is made of two fiberglass boards stacked together, and the thickness of each fiberglass board is 1-2mm. The unloading plate 2 is a fiberglass board with a thickness of 1mm, and the clamping plate 3 is a fiberglass board with a thickness of 0.5mm, to ensure the support strength.

[0030] This utility model has a simple structure and low cost. It effectively solves the problems of the top of the ring pad of the machine pin socket 41 of the flexible circuit board protruding, the top of the wire breaking, and micro-breakage when manually inserting the connector, thereby improving the production yield and reducing the production difficulty.

[0031] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
