Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electronic device processing, and in particular to an SMT packaging product bending and shaping jig. BACKGROUND

[0002] With the continuous development of science and technology, the importance of electronic products in people's lives is increasing. As a commonly used electronic manufacturing technology, SMT (Surface Mount Technology) is widely used in the production engineering of electronic products. SMT is a circuit connection technology that installs a pinless or short lead surface mounted component on the surface of a printed circuit board or the surface of another substrate, and is welded and assembled by reflow soldering or dip soldering.

[0003] After the existing SMT packaging product is processed and prepared, the pins need to be shaped for easy fixation on the circuit board. Since the pins are plated with tin and have a soft texture, the pins are usually shaped by hand. For example, a processing tool such as tweezers and needle-nose pliers is used to first straighten the pins with tweezers, then bend the pins one by one by clamping the root of the pin with needle-nose pliers, and finally trim and cut the pins.

[0004] At present, a Chinese patent with publication number CN214282001U discloses an integrated circuit SMT packaging product shaping device, which comprises a processing seat, a support column is fixedly connected to the top outer wall of the processing seat by welding, a power box is fixedly connected to the top end of the support column, a blower is arranged on the top outer wall of the power box, a pressing plate is arranged in the power box, an inflatable air bag is arranged on the upper end of the pressing plate, a connecting rod is fixedly connected to the bottom outer wall of the pressing plate, a shaping module is fixedly connected to the lower end of the connecting rod through the bottom end outer wall of the power box, a clamping table is arranged in the processing seat, a storage groove is arranged on the top end of the clamping table, a hydraulic device is fixedly connected to the inner wall of the two side ends of the processing seat, a hydraulic rod is fixedly connected to the hydraulic device, and a shearing cutter is fixedly connected to the top end of the hydraulic rod.

[0039] With reference to Figure 1 and Figure 3 When the SMT packaging products are processed, a plurality of packaging products are placed in the placing grooves 351 of the plurality of placing blocks 35 one by one, and a part of the connecting pins is arranged on the lower pin grooves 352. The motor 7 drives the rotating gear 8 to rotate, and the driven gear ring 9 and the supporting circular plate 5 rotate under the driving action of the rotating gear 8. When one of the lower extrusion arc plates 32 rotates to a position corresponding to the upper extrusion arc plate 31 in the vertical direction, the operator rotates the rotating handle 22, the driving rod 23 and the connecting rod 25 drive the lifting rod 21 to move downward and drive the upper extrusion arc plate 31 to descend. The top end of the packaging product is embedded in the accommodating cavity 332 of the upper forming block 33, and the connecting pin is bent under the action of the upper pin groove 333 and the lower pin groove 352. The arrangement of the connecting pad reduces the possibility of damage to the connecting pin in the process of bending and forming, and the arrangement of the crank connecting rod structure facilitates the operator to adjust the extrusion forming strength according to needs, which helps to improve the processing quality of the connecting pin.

[0040] With reference to Figure 1 , Figure 3 and Figure 4After the bending and extruding of a batch of connecting pins is completed, the motor 7 is started again to drive the bearing disc 5 to rotate, and the formed product is moved out from below the upper extruding arc plate 31, and another batch of unprocessed packaging products is moved to below the upper extruding arc plate 31 for uninterrupted and high-efficiency forming operation. When the bearing disc 5 rotates, the limiting block 43 slides in the limiting ring groove 451. When the bent and formed product rotates to above the ejection protrusion 452, the sliding rod 42 slides upward, and the reset spring 44 is extruded and deformed to accumulate elastic potential energy. The supporting block 41 moves upward and ejects the packaging product in the placing groove 351, achieving automatic ejection of the packaging product and helping to improve the processing efficiency of the device. The lower forming block 34 that has completed ejection continues to rotate with the bearing disc 5, and the sliding rod 42 slides downward under the action of the reset spring 44 to achieve automatic reset, and the supporting block 41 moves back into the ejection through groove 12.

[0041] Reference Figure 3 Since the upper extruding arc plate 31 is connected with the upper forming block 33 by bolts, and the lower extruding arc plate 32 is connected with the lower forming block 34 by bolts, different upper forming blocks 33 and lower forming blocks 34 can be selected and installed on the upper extruding arc plate 31 and the lower extruding arc plate 32 according to different packaging products during processing. When the upper forming block 33 moves downward for extruding and forming, the cutting knife 11 is embedded in the cutting groove 341 of the lower forming block 34 to cut off the excess connecting pins, avoiding trimming of the connecting pins in subsequent operation and helping to improve the processing efficiency of the packaging product.

[0042] The implementation principle of the SMT packaging product bending and shaping jig in the embodiment of the application is as follows: when processing the SMT packaging product, the packaging products are placed one by one in the placing grooves 351 of the placing blocks 35. When one of the lower extruding arc plates 32 rotates to correspond to the upper extruding arc plate 31 in the vertical direction, the upper extruding arc plate 31 descends, and the connecting pins are bent under the action of the upper pin groove 333 and the lower pin groove 352. After a batch of products is processed, the bearing disc 5 rotates, and another batch of packaging products is moved to below the upper extruding arc plate 31 for uninterrupted and high-efficiency forming operation. When the bent and formed product rotates to above the ejection protrusion 452, the supporting block 41 moves upward and ejects the packaging product in the placing groove 351, achieving automatic ejection of the packaging product and helping to improve the processing efficiency of the device.

[0043] The above are preferred embodiments of the application, which do not limit the protection scope of the application. Any equivalent changes made according to the structure, shape, and principle of the application should be covered within the protection scope of the application.
