[0002] A PCBA, also known as a printed circuit board (PCB), is a crucial electronic component that supports and connects electronic components. Because it's manufactured using electronic printing technology, it's called a "printed" circuit board. Before the advent of PCBs, electronic components were interconnected directly via wires to create a complete circuit.

[0003] A Chinese utility model patent, granted with the publication number CN 215280283 U, discloses a PCBA auxiliary soldering jig comprising a base plate, a fixing slot, a fixing rod, and a support rod. The base plate's upper surface is provided with a fixing slot, and a support rod is movably mounted on the base plate's inner bottom end. A fixing mechanism is provided on one upper side of the base plate, comprising a first slide, a fixing rod, a mounting slot, a motor, a threaded rod, a linear slide, a second slider, and a threaded block. A support mechanism is provided on the base plate's inner bottom end, comprising a second slide, a support rod, a slide rod, and a first slider. An infrared sensor and a pressure sensor are mounted within the fixing rod. The utility model utilizes a fixing and support mechanism on the base plate to automatically secure the PCBA, replacing traditional manual securing methods. This improves securing efficiency, thereby increasing production efficiency, while preventing PCBA pinching and thus reducing product defect rates.

[0004] While the aforementioned existing solutions automatically secure the PCBA using a fixing and supporting mechanism, electronic components within the fixture, such as sensors and controllers, can malfunction. These failures can cause the fixing mechanism to malfunction, impacting production efficiency and product quality. Therefore, a PCBA soldering auxiliary jig is urgently needed to address this issue.

[0026] Specifically, through the provision of the guide groove 14 , the guide groove 14 is provided through the inner and outer ends of the rotating plate 12 away from the rotating seat 11 . During the sliding process of the sliding block 15 , the guide groove 14 can play a guiding role.

[0027] See also Figure 1-6 The sliding block 15 is movably connected to the second screw rod 16 , the outer surface of the second screw rod 16 is fixedly connected to the rotating ring 17 , and the bottom of the second screw rod 16 is fixedly connected to the rubber pad 27 .

[0028] Specifically, by setting the second screw rod 16 and rotating the rotating ring 17, the second screw rod 16 can push the rubber pad 27 to generate a lifting displacement, so that the rubber pad 27 can be pressed against the PCBC board to play a positioning role.

[0029] See also Figure 1-6 The first spring column 21 is fixedly connected between the connecting plate 20 and the top plate 22 , and the side surface of the top plate 22 is fixedly connected to the inside of the sliding block 15 .

[0030] Specifically, through the setting of the first spring column 21, when the pressing plate 18 is pressed, the pressing plate 18 will pull the limit block 19 toward the inside of the sliding block 15 through the connecting plate 20, so that the limit block 19 contacts the limit of the guide groove 14, allowing the sliding block 15 to slide.

[0031] See also Figure 1-6 The inside of the operating panel 1 is fixedly connected to a guide plate 2, and the outer surface of the guide plate 2 is slidably connected to a side clamping plate 3.

[0032] Specifically, through the setting of the guide plate 2, when the side clamping plate 3 is clamped, the guide plate 2 can play a guiding role, making the guide plate 2 more stable when clamping, and the surface of the side clamping plate 3 is sloped, which can be suitable for PCBAs of different specifications and sizes.

[0033] See also Figure 1-6 The side surface of the side splint 3 is fixedly connected to the first connecting block 23 , and the outer surface of the first connecting block 23 is movably connected to the second connecting block 24 .

[0034] Specifically, by setting the second connecting block 24, the first connecting block 23 and the third connecting block 25 can be effectively connected, so that the third connecting block 25 can effectively play a buffering role when pushing the first connecting block 23 to clamp, thereby avoiding damaging the PCBA.

[0035] See also Figure 1-6 The outer surface of the second connecting block 24 is movably connected to the third connecting block 25 , and the side surface of the second connecting block 24 is fixedly connected to the second spring column 26 .

[0036] Specifically, through the provision of the second spring column 26, when the third connecting block 25 pushes the first connecting block 23, both ends of the second connecting block 24 will be received inside the third connecting block 25 and the first connecting block 23, effectively improving the flexibility of the device.

[0037] See also Figure 1-6 The side surface of the third connecting block 25 is fixedly connected with a fixing ring 4, the interior of the fixing ring 4 is movably connected with a first screw rod 5, and the side of the first screw rod 5 away from the third connecting block 25 is fixedly connected with a rotating rod 6.

[0038] Specifically, by setting the first screw rod 5 and rotating the rotating rod 6 , the rotating rod 6 can push the side clamping plate 3 to the center of the operating panel 1 for clamping.

[0039] See also Figure 1-6 The side surface of the operating panel 1 is fixed with an anti-skid plate 8 , which is fixedly connected to the four corners of the operating panel 1 in four groups.

[0040] Specifically, by setting the anti-skid plate 8, the bottom of the anti-skid plate 8 is made of anti-skid rubber material. When the operating panel 1 is placed on the operating table, the anti-skid plate 8 can play an anti-skid role and prevent the operating panel 1 from slipping during operation.

[0041] Working principle: When in use, the operator places the PCBA on the upper surface of the side clamping plate 3, rotates the rotating rod 6, so that the rotating rod 6 drives the first screw rod 5 to rotate synchronously, so that the first screw rod 5 pushes the side clamping plate 3 to move on the guide plate 2. When the side clamping plate 3 is clamped to the PCNA, the side clamping plate 3 will first push the first connecting block 23 to squeeze toward the third connecting block 25. Under the action of the second spring column 26, the first connecting block 23 will play a clamping and buffering role, making the side clamping of the side clamping plate 3 more firmly. Then, the slider 9 is inserted into the side surface of the operating panel 1 along the guide plate 7, and the rotating plate 12 is rotated so that the end of the rotating plate 12 away from the rotating seat 11 is rotated to the PCBA. From the top, press the pressing plate 18, so that the pressing plate 18 drives the limiting block 19 to move toward the inside of the sliding block 15, thereby releasing the limiting block 19 from limiting the guide groove 14, and slide the sliding block 15. After the sliding block 15 slides to a suitable position, release the pressing plate 18. Under the action of the first spring column 21, the first spring column 21 will push the limiting block 19 to rest against the inner wall of the guide groove 14, thereby achieving the limiting fixation of the sliding block 15. Then rotate the rotating ring 17, so that the second screw rod 16 pushes the rubber pad 27 to move downward, so that the rubber pad 27 rests against the upper surface of the PCBA, thereby preventing the PCBA from falling off during operation, resulting in welding errors and scrapping.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
