Description

Technical Field

[0001] This utility model relates to the field of SMT (Surface Mount Technology) for walkie-talkies, and in particular to an SMT wiping device. Background Technology

[0002] SMT (Surface Mount Technology) is an abbreviation for a series of processes performed on a PCB (Printed Circuit Board). It is one of the most popular technologies and processes in the electronics assembly industry. SMT assembly for walkie-talkies involves assembling the electronic components required for the walkie-talkie onto the circuit board using SMT technology. SMT technology enables high-density assembly of electronic components, making the walkie-talkie circuit board more compact, smaller, and lighter, while improving production efficiency. During the process, SMT components need to be wiped, but current wiping devices are cumbersome and do not effectively remove dust and impurities, affecting the quality of the SMT assembly.

[0003] To address the aforementioned issues, existing patent (CN213670606U) discloses a wiping device for SMT chip mounting, comprising a base plate, a support plate, a blower cleaning unit, and a threaded shaft control unit. The base plate has top rods fixedly connected to its front and rear sides. Four telescopic rods are fixedly connected to the inner sides of the top rods and are evenly distributed on two of the top rods. Four springs are movably sleeved on the sides of the telescopic rods. Two clamping rods are fixedly connected to the inner ends of the telescopic rods. An SMT chip is placed in the center of the upper surface of the base plate. The support plate is fixedly connected to the upper surface of the base plate. Two support plates are evenly distributed. A threaded shaft is rotatably connected to the upper part of each support plate, and a sliding rod is fixedly connected to the upper part of the support plate. This wiping device for SMT chips effectively cleans dust and impurities during wiping, is simple and convenient, and ensures the quality of the SMT chips.

[0004] However, in the aforementioned prior art, when the clamping rod fixes SMT components of different sizes, the brush cannot adaptively adjust the working length, causing the clamping rod to block the brush's wiping operation. This results in a decrease in the cleanliness of the SMT components and a reduction in the brush's lifespan. Utility Model Content

[0021] In this specific embodiment, the fixing block 102 is fixedly connected to the worktable 101 and located below the worktable 101. The auxiliary components include a clamping member, a support frame 109, a telescopic cylinder 110, a drive rod 104, a placement plate 112, and a lifting member.

The SMT component is placed above the placement plate 112. The telescopic cylinder 110 is fixed inside the support frame 109. The telescopic cylinder 110 drives the drive rod 104 to move upward. The drive rod 104 pushes the placement plate 112 upward, so that the SMT component and the clamping member are on the same horizontal plane. The clamping member fixes the SMT component. The lifting member is used to adjust the working height of the wiping mechanism 119. The wiping mechanism 119 has been described in the prior art CN213670606U. It uses a brush to wipe the SMT component, so it will not be described in detail.

The drive motor 103 drives the adjusting rod 111 to rotate, and the moving block 105 drives the push plate 106 to move. When the clamping plate 108 clamps the SMT chip, the telescopic spring 107 is compressed to achieve elastic clamping of the SMT chip. The synchronous motor 117 drives the drive gear to rotate. Through the meshing of the drive gear 118 and the rack 114, the rack 114 slides upward in the support block 113. The lifting block 115 pushes the wiping mechanism 119 to perform lifting operations. The wiping mechanism 119 performs wiping operations on the SMT chip, which can effectively avoid the device blocking the brush and ensure the cleanliness of the SMT chip wiping operation.
