Description

Technical Field

[0001] This utility model relates to the field of circuit board welding technology, and in particular to a rapid welding fixture for integrated circuit boards. Background Technology

[0002] When soldering components for integrated circuits, the component's pins must first be inserted from the top of the circuit board until they protrude from the bottom. Then, the circuit board is flipped over to expose the pins located at the bottom. Finally, the circuit board is soldered to the component's pins.

[0003] To prevent the circuit board from falling out of the tooling slot after flipping, a limiting component is needed to limit the circuit board before flipping, such as the solution disclosed in the utility model patent with authorization announcement number CN219536439U. Although the above solution can realize the welding operation after the circuit board is flipped, the electric cylinder needs to be actively operated before flipping and after welding to limit and release the circuit board. The overall operation process is still relatively cumbersome, and the overall welding efficiency still needs to be improved.

[0004] Therefore, it is necessary to invent a rapid soldering fixture for integrated circuit boards to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a rapid welding fixture for integrated circuit boards. This fixture can actively block the positioning groove during the backward flipping of the support plate to prevent the circuit board from falling out after flipping. Simultaneously, when the support plate is flipped forward, it can actively release the obstruction of the positioning groove, allowing operators to directly remove the circuit board. This makes it more convenient to use and further improves welding efficiency. It addresses the problem in the background art where, before flipping and after welding, the electric cylinder needs to be actively operated to limit and release the circuit board, making the overall operation process relatively cumbersome and the overall welding efficiency still needing improvement.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a rapid soldering fixture for integrated circuit boards, comprising:

[0007] A rotating support assembly is provided, which is used to drive the circuit board support assembly to rotate.

[0008] A circuit board carrier assembly for supporting an integrated circuit board; and

[0009] Two sets of mutually rotationally symmetrical circuit board limiting assemblies, each set of circuit board limiting assemblies includes a limiting beam fixedly disposed on the inner side of the U-shaped base, the top of the inner side of the limiting beam is provided with a guide slope, the circuit board limiting assembly also includes a sliding shaft that slides through the support plate, one end of the sliding shaft is attached to the side of the limiting beam and the other end is fixedly connected to an L-shaped limiting plate that slides against the top of the support plate, and a return spring is sleeved on the outer side of the sliding shaft and fixedly connected between the support plate and the L-shaped limiting plate.

[0010] According to at least one embodiment of the integrated circuit board rapid soldering fixture of the present disclosure, the supporting rotation assembly includes a U-shaped base, and a support block is fixedly provided on both the inner front end and the inner rear end of the U-shaped base.

[0011] According to at least one embodiment of the integrated circuit board rapid welding fixture of the present disclosure, a rotating shaft is rotatably nested in the middle of the inner side of the U-shaped base via a bearing, and a manual turntable is fixedly sleeved at both ends of the outer side of the rotating shaft.

[0012] According to at least one embodiment of the present disclosure, a rapid soldering fixture for integrated circuit boards includes a circuit board support assembly comprising a connecting sleeve fixedly sleeved on the outside of a rotating shaft, a support plate fixedly disposed at the front end of the connecting sleeve, and the bottom of the support plate abutting against the top of an adjacent support block.

[0013] According to at least one embodiment of the present disclosure, a rapid welding fixture for an integrated circuit board is provided on the top of the support plate, which is adapted to the integrated circuit board, and a clearance channel penetrating the support plate is provided on the bottom inner side of the positioning groove in a vertical direction.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention incorporates a circuit board limiting assembly. When the support plate is attached to the top of the front support block, the two sliding shafts abut against the bottom inner sides of the two limiting beams. At this time, the return spring is stretched, and the L-shaped limiting plate does not obstruct the top of the positioning groove. Subsequently, when the circuit board is placed inside the positioning groove and the support plate is rotated, the support plate causes the sliding shafts to gradually disengage from the inner side of the limiting beams. When the limiting beams no longer obstruct the sliding shafts, the stretched return spring causes the L-shaped limiting plate to move closer to the positioning groove, thereby securing the top of the positioning groove. The edges are blocked to ensure that the circuit board cannot fall out after the carrier plate is flipped. After subsequent welding, when the carrier plate is flipped forward and reset, the sliding shaft guided by the guide slope abuts against the bottom of the inner side of the limiting beam, thereby actively releasing the obstruction of the positioning groove. Compared with the prior art, this utility model can actively block the positioning groove during the backward flipping of the carrier plate to prevent the circuit board from falling out after flipping. At the same time, when the carrier plate is flipped forward, it can actively release the obstruction of the positioning groove, making it convenient for operators to directly remove the circuit board. It is more convenient to use and further improves welding efficiency. Attached Figure Description

[0024] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0025] Figure 1 This is a schematic diagram of the overall structure of a rapid soldering fixture for integrated circuit boards according to one embodiment of the present disclosure.

[0026] Figure 2 This is a schematic diagram of the support rotation assembly 1 and the circuit board carrier assembly 2 of a rapid soldering fixture for integrated circuit boards according to one embodiment of the present disclosure.

[0027] Figure 3 This is a schematic diagram of the circuit board positioning assembly 3 of a rapid soldering fixture for integrated circuit boards according to one embodiment of the present disclosure.

[0028] like Figures 1-3 As shown, the rapid soldering fixture for integrated circuit boards disclosed herein may include: a support rotation assembly 1, a circuit board carrying assembly 2, and two sets of mutually rotationally symmetrical circuit board positioning assemblies 3, etc.

[0029] like Figure 2 As shown in this disclosure, the supporting rotating assembly 1 includes a U-shaped base 11, which is integrally stamped from Q235 cold-rolled steel plate. Four M8 mounting holes (not shown) are reserved at the bottom, which can be fixed to the workbench with expansion bolts to ensure no shaking when flipping. Support blocks 12 are fixedly installed on the inner front end and inner rear end of the U-shaped base 11. When the bearing plate 22 is placed horizontally, its bottom is completely in contact with the top of the support block. The load of the bearing plate 22 is completely borne by the support block, avoiding deformation of the rotating shaft 13 due to force. The rotating shaft 13 is rotatably nested in the middle of the inner side of the U-shaped base 11 through a bearing. It is made of 40Cr alloy round steel. The two ends of the shaft are rotatably nested with the U-shaped base 11 through deep groove ball bearings to ensure smooth rotation without jamming. The service life can reach more than 100,000 times. Manual turntables 14 are fixedly sleeved at both ends of the outer side of the rotating shaft 13.

[0030] Therefore, when it is necessary to flip the support plate 22 backward or forward, any manual turntable 14 can be rotated clockwise or counterclockwise. When the manual turntable 14 rotates, it drives the connecting sleeve 21 to rotate through the rotating shaft 13. The connecting sleeve 21 then drives the support plate 22 to flip backward or forward. The two support blocks 12 can support the support plate 22 when it is flipped backward or forward, so that the support plate 22 remains horizontal after flipping backward or forward.

[0031] like Figure 2 As shown, in a preferred embodiment, the circuit board support assembly 2 includes a connecting sleeve 21 fixedly sleeved on the outside of the rotating shaft 13. A support plate 22 is fixedly mounted on the front end of the connecting sleeve 21. The support plate is made of aerospace aluminum by milling and the surface of the support plate is anodized to be corrosion resistant and insulating, thus preventing the circuit board from communicating with the tooling during soldering. The bottom of the support plate 22 is attached to the top of the adjacent support block 12. A positioning groove 23 adapted to the integrated circuit board is opened on the top of the support plate 22. An avoidance channel 24 penetrating the support plate 22 is opened on the bottom of the inner side of the positioning groove 23 along the vertical direction.

[0032] This allows the circuit board to be soldered to be placed inside the positioning groove 23. Then, the pins of multiple components are inserted from the top of the circuit board into the holes on the surface of the circuit board, with the bottom of the pins extending to the inside of the clearance channel 24. When the carrier plate 22 is flipped back, the components cannot fall out due to the friction between the pins and the holes, and the circuit board cannot fall out due to the obstruction of the circuit board limiting component 3.

[0033] like Figure 3 As shown in this disclosure, any set of circuit board limiting components 3 includes a limiting beam 31 fixedly disposed inside the U-shaped base 11. A guide slope 32 is provided on the top of the inner side of the limiting beam 31. The circuit board limiting component 3 also includes a sliding shaft 33 that slides through the bearing plate 22. The shaft is made of 304 stainless steel round bar. The end of the shaft that contacts the limiting beam is ground into a hemispherical shape to reduce friction with the side of the limiting beam 31. One end of the sliding shaft 33 is attached to the side of the limiting beam 31, and the other end is fixedly connected to an L-shaped limiting plate 34 that slides against the top of the bearing plate 22. A return spring 35 is sleeved on the outside of the sliding shaft 33 and fixedly connected between the bearing plate 22 and the L-shaped limiting plate 34.

[0034] Therefore, when the support plate 22 is attached to the top of the front support block 12, the two sliding shafts 33 respectively abut against the bottom inner side of the two limiting beams 31. At this time, the return spring 35 is in a stretched state, and the L-shaped limiting plate 34 does not obstruct the top of the positioning groove 23. Subsequently, when the circuit board is placed inside the positioning groove 23 and the support plate 22 is rotated, the support plate 22 drives the sliding shafts 33 to gradually disengage from the inside of the limiting beams 31. When the limiting beams 31 no longer obstruct the sliding shafts 33, the stretched return spring 35 drives the L-shaped limiting plate 34 to move closer to the positioning groove 23, thereby abutting the top of the positioning groove 23. The edges are blocked to ensure that the circuit board cannot fall out after the carrier plate 22 is flipped. After subsequent welding is completed, when the carrier plate 22 is flipped forward and reset, the sliding shaft 33 guided by the guide slope 32 abuts against the bottom of the inner side of the limiting beam 31 again, thereby actively releasing the obstruction of the positioning groove 23. Compared with the prior art, this utility model can actively block the positioning groove 23 during the backward flipping of the carrier plate 22 to prevent the circuit board from falling out after flipping. At the same time, when the carrier plate 22 is flipped forward, it can actively release the obstruction of the positioning groove 23, making it convenient for operators to directly remove the circuit board. It is more convenient to use in practice and further improves welding efficiency.

[0035] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0036] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
