Description
Technical Field
[0001] This utility model belongs to the field of chip testing technology, specifically a device for testing the welding strength of electronic components. Background Technology
[0002] Electronic component solder joint strength testing equipment is primarily used to evaluate the mechanical strength and reliability of solder joints to ensure the long-term stable operation of electronic products. Testing the strength and reliability of electronic component connections simulates the impact of external forces on the connectors. By applying static or dynamic push or pull forces, it monitors and records the sample's performance during stress to determine key performance indicators such as solder joint strength, deformation, fatigue life, and failure point. Electronic component solder joint strength testing equipment is a crucial tool for ensuring the reliability of electronic products, providing strong support for product quality control through high-precision and automated testing methods.
[0003] However, common welding strength testing devices, due to the destructive testing of thrust, will cause a large number of electronic components to fall off, which can easily damage the equipment and make the inside dirty and messy, requiring manual cleaning, resulting in low work efficiency and high capital costs. Utility Model Content

[0005] The technical solution adopted by this utility model is as follows: an electronic component welding strength testing device includes a housing. A vertical displacement groove is provided on the left side of the interior of the housing. A sliding fixed base is slidably connected inside the vertical displacement groove. A translation motor is fixedly connected to the right side of the sliding fixed base. A horizontal displacement screw is rotatably connected to the right side of the translation motor. A worktable base is slidably connected to the middle of the horizontal displacement screw. A lifting rod is fixedly connected below the worktable base. A horizontal displacement groove is slidably connected below the lifting rod. Waste outlets are provided at both ends of the horizontal displacement groove. Inclines are fixedly connected to both sides of the horizontal displacement groove.
[0006] By adopting the above technical solution, the translation motor starts and drives the horizontal displacement screw to rotate, which in turn moves the worktable base. The circuit board fixed on the worktable base is sent to the pusher under the fixed block for welding strength testing. After the test, some electronic components will fall due to the thrust test. The fallen electronic components will slide down the ramp into the horizontal displacement chute. The movement of the worktable base will drive the lifting rod to slide in the horizontal displacement chute, pushing the electronic components that have fallen into the horizontal displacement chute into the waste outlet. This achieves cleaning of the inside of the box, keeps the inside of the box clean, reduces manual cleaning, improves work efficiency, reduces labor costs, and at the same time ensures the accuracy of test data.

[0012] By adopting the above technical solution, the fastening block can be fastened and loosened by manually rotating the fastening knob to drive the fastening reverse screw to rotate. At the same time, the left and right translation knob can be manually rotated to drive the left and right translation base to move slightly left and right, adjusting the position of electronic components on the circuit board. Meanwhile, the sensor can measure the thrust generated during the thrust detection to ensure that the detection is carried out smoothly.
[0013] In a preferred embodiment, a fixing block is fixedly connected to the top of the box, an infrared emitter is fixedly connected to the upper front end of the fixing block, and a pusher is fixedly connected to the bottom of the fixing block.

[0017] By adopting the above technical solutions, the equipment can be kept level.
[0018] In a preferred embodiment, waste outlets are provided on the bottom and right side of the container.
[0019] By adopting the above technical solution, the electronic components that fell during the test were removed.
[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0021] In this invention, the translation motor starts and drives the horizontal displacement screw to rotate, which in turn moves the worktable base. This moves the circuit board fixed on the worktable base to the pusher below the fixed block for welding strength testing. After the test, some electronic components will fall due to the pushing force. The fallen electronic components will slide down the ramp into the horizontal displacement chute. The movement of the worktable base will cause the lifting rod to slide in the horizontal displacement chute, pushing the electronic components that have fallen into the chute into the waste outlet. This achieves the cleaning of the inside of the box, keeps the inside of the box clean, reduces manual cleaning, improves work efficiency, reduces labor costs, and ensures the accuracy of test data. It also prevents the equipment from being blocked by a large number of fallen electronic components, thus reducing financial costs. Attached Figure Description

After the test, some electronic components will fall due to the pushing force. The fallen electronic components will slide down the ramp 7 into the horizontal displacement chute 9. The movement of the worktable base 6 will drive the lifting rod 8 to slide in the horizontal displacement chute 9, pushing the electronic components that have fallen into the horizontal displacement chute 9 into the waste outlet 10. This achieves the cleaning of the inside of the box 1, keeping the inside of the box 1 clean, reducing manual cleaning, improving work efficiency, reducing labor costs, and ensuring the accuracy of test data.
