Description

Technical Field

[0001] The utility model relates to the technical field of SMD component detection, in particular to an SMD component detection device. Background Art

[0002] SMD stands for surface mount device, which is a type of SMT component. Surface mount components were introduced about twenty years ago and ushered in a new era. From passive components to active components and integrated circuits, they all eventually became surface mount devices (SMD) and can be assembled through pick-and-place equipment. For a long time, people believed that all pin components could eventually be packaged in SMD. SMD components are generally tested for their solderability. The solderability test is mostly done by the inspector first holding the SMD component body with stainless steel tweezers and immersing it in a tin pot at 235±5℃ or 230±5℃. After taking it out, the soldering end is checked under a 20x microscope for tinning. It is required that more than 90% of the component soldering end is tinned.

[0003] The intelligent detection and classification equipment for ceramic ultra-high frequency SMD components with publication number CN212494048U has the following defects in use:

[0004] The robot unit of the device includes a lifting cylinder, a lifting plate connected to the output end of the lifting cylinder, two vacuum suction units vertically connected to the two ends of the lifting plate, a third mounting plate, and a translation cylinder for driving the third mounting plate to move between the workpiece tray and the classification tray. The lifting cylinder is installed on the third mounting plate. This allows high detection accuracy, high work efficiency and reduced costs. However, in actual use, the patches are generally collected in rolls. If the entire roll is immersed in the detection liquid, it is very likely to cause uneven immersion, and the temperature of the tin pot is too high, which is very likely to cause harm to the staff. For this reason, we propose an SMD component detection device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an SMD component detection device, which solves the problem that in actual use, patches are generally collected in rolls. If the entire roll is immersed in the detection liquid, it is very likely to cause uneven immersion, and the temperature of the tin pot is too high, which is very likely to cause harm to the staff.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] 1. By setting the first pressing block, the design of the first pressing block can compress the part of the patch passing through the through hole. After selecting the length of the part to be tested, the first pressing block is used to compress and stabilize it, so that only a part of the extended patch needs to be tested during the test.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] refer to Figure 1-Figure 4, an SMD component detection device, a base 1, a support frame 2 is fixedly installed on the top surface of the base 1, an electric push rod 3 is fixedly installed on the top surface of the support frame 2, the output end of the electric push rod 3 extends into the bottom surface of the support frame 2, and a fixed block 4 is fixedly installed on the output end of the electric push rod 3, a placement groove 5 is opened on one side of the fixed block 4, a sliding groove 6 is opened on the inner bottom surface of the placement groove 5, and a first pressing block 7 is provided in the internal movable sleeve of the sliding groove 6. The design of the first pressing block 7 can press a part of the patch passing through the through hole, and the length of the part to be detected is selected and then pressed and stabilized by the first pressing block 7, so that only a part of the extended patch needs to be detected during detection, which is more convenient to remove after detection than the entire detection, and at the same time While ensuring the inspection quality, the workload can be reduced. Two sliding holes 8 are provided on one side of the fixed block 4. Two sliding rods 9 are fixedly installed on one side of the first pressing block 7. The sliding rod 9 consists of a cylindrical sliding part and a disc-shaped limiting part. The sliding part of the sliding rod 9 is movably sleeved with a spring 10. The spring 10 is limited by the limiting part of the sliding rod 9 and one side of the fixed block 4. A through hole is provided on the inner bottom surface of the sliding groove 6. When the first pressing block 7 is pulled, after a part of the patch is put into the through hole, the elastic force of the spring 10 can force the first pressing block 7 to return to its original position after letting go, thereby ensuring that the stability of the patch when clamping is enhanced, and avoiding the phenomenon of the growth of the detection part due to factors such as its own weight during the detection process;

[0023] A second pressing block 11 is arranged inside the placement groove 5. The design of the second pressing block 11 can clamp the collected patch roll, which can ensure that the overall position of the patch roll can be fixed during the detection process, and will not cause the extracted detection part to slide, affecting the actual detection effect or even causing the high-temperature liquid inside the tin pot 19 to splash. A connecting pipe 12 is fixed on one side of the second pressing block 11, and a rotating rod 13 is arranged at one end of the fixed block 4. One end of the rotating rod 13 extends into the interior of the placement groove 5. The rotating rod 13 consists of a cylindrical rotating part and disc-shaped clamping parts at both ends. The outer wall surface of the rotating part of the rotating rod 13 is provided with a thread, and the clamping part of the rotating rod 13 is clamped with the connecting pipe 12. By rotating the rotating rod 13, the second pressing block 11 can be driven to move inward or outward. It can be adjusted according to different patch rolls to increase the flexibility of the device. A contact block 14 is fixedly installed on one side of the second pressing block 11, and a fixing hole 15 is opened on one side of the contact block 14. Through the design of the fixing hole 15 and the contact block 14, the friction can be increased or the clamping method can be used. The device is enhanced to have a clamping capacity for the patch roll, and further increase the stability and safety of the device. A friction block 16 is fixedly installed on one side of the first pressing block 7. The material of the friction block 16 is rubber. Through the design of the friction block 16, the pressing capacity of the detection part can be enhanced by increasing the friction force. At the same time, its rubber texture can avoid damage due to excessive force during the pressing process, resulting in unnecessary losses. A fixing box 17 is fixedly installed on the top surface of the support frame 2. The design of the fixing box 17 can stabilize the electric push rod 3 to avoid the influence of its own vibration on the stability of the fixing block 4 during operation, thereby ensuring the overall stability of the device. A fixing groove 18 is provided on the top surface of the base 1. A tin pot 19 is fixedly installed inside the fixing groove 18. The inside of the tin pot 19 is provided with a heat-resistant coating. The design of the tin pot 19 can store the high-temperature solution required for the detection. Since the temperature of the solution needs to reach a maximum of 240 degrees during the patch detection, the internal heat-resistant coating can effectively protect the tin pot 19 and increase its service life.
