Description

Technical Field

[0001] The utility model relates to an auxiliary robot for clamping a circuit board. Background Art

[0002] The auxiliary clamping robot next to the soldering circuit board is an automated production equipment that can precisely clamp and fix the circuit board to ensure the accuracy and stability of the soldering process. This robot is usually equipped with high-precision sensors and control systems, which can monitor the position and posture of the circuit board in real time and adjust the clamping force to ensure the soldering quality. At the same time, the clamping robot can also automatically complete the positioning and alignment of the circuit board according to the pre-set program, improving production efficiency and product quality. Figure 7 As shown, the existing circuit board includes a circuit board body 61 and a liquid crystal screen 62 welded on the circuit board body 61. The left and right ends of the circuit board body 61 are provided with circuit board positioning recesses 64. The circuit board body 61 is provided with an iron column 65 whose bottom is higher than the bottom of the circuit board body 61 near the circuit board positioning recess 64. When the auxiliary clamping robot clamps the circuit board body 61, it is found that the clamping of the circuit board is not stable and reliable enough during actual welding. A large amount of iron filings are easily generated on the circuit board when welding the circuit board. If the clamping is too tight, it is easy to damage the circuit board. If the clamping is too loose, it is easy to cause the circuit board to shake, shift or even fall off during the cleaning process of the circuit board, affecting the progress of the next workstation. In view of this, the existing auxiliary clamping robot is improved and optimized. Utility Model Content
