Description

Technical Field

[0001] The utility model relates to the field of SMT patches, in particular to SMT patch detection equipment. Background Art

[0002] SMT is a surface assembly technology, also known as surface mounting or surface mounting technology. It is the most popular technology and process in the current electronic assembly industry. It is a circuit assembly technology that mounts pinless or short-lead surface mounting components on the surface of a printed circuit board or other substrate, and assembles them by soldering through methods such as reflow soldering or dip soldering. During the production and processing of SMT patches, various inspections and measurements are required for SMT patches.

[0003] After massive search, it is found that the Chinese patent with the prior art publication number CN215011380U discloses a SMT patch quality inspection device. The patent puts the SMT patch into the upper placement slot and presses it lightly so that the four corners of the SMT patch are adsorbed by the suction cup, and then the stepper motor drives the SMT patch through the conveyor roller and the conveyor belt to move it to the bottom of the detector for inspection. After the inspection is completed, the stepper motor drives another SMT patch to move to the bottom of the detector again. This is repeated continuously, and the inspected SMT patch is continuously moved until it moves to the position of a conveyor roller. However, in this scheme, since qualified SMT patches and unqualified SMT patches are both in the upper placement slot after inspection, it is difficult to directly remove unqualified SMT patches, resulting in the need for staff to screen qualified SMT patches and unqualified SMT patches after SMT patch inspection. The process is cumbersome and affects the staff's inspection of SMT patches. Therefore, based on the above search and combined with the prior art, the utility model proposes an SMT patch inspection device to solve the above problems. Utility Model Content

[0011] Furthermore, a fixed bin for collecting unqualified SMT patches is fixedly installed on one side of the bracket on the left side.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The SMT patches can be inspected by cooperating with the support, the conveyor body, the fixing frame and the detector.

[0025] Through the provided bracket 1, the staff places the SMT patch on the conveyor belt body 2 between the two brackets 1, and the conveyor belt body 2 transports the SMT patch forward to the bottom of the fixed frame 3. The detector 4 inside the fixed frame 3 can detect the SMT patch, and the qualified SMT patch continues to move forward. When there is an unqualified SMT patch, the drive motor 20 is started, and the output rotation of the drive motor 20 drives the first connecting rod 21 to rotate. The rotation of the first connecting rod 21 causes the second connecting rod 24 to move forward through the rotating shaft 23 on the first connecting rod 21. The forward movement of the second connecting rod 24 drives the gear 17 to roll forward and causes the second connecting rod 24 to rotate around the rotating shaft 23 on the gear 17. The forward rolling of the gear 17 will also drive the support shaft 13 to rotate and move forward inside the connecting hole 12. The gear 17 moves forward along the first rack 16 to drive the second rack 18 to move forward. The second rack 18 moves forward to drive the rubber block 19 to move forward, and the rubber block 19 moves forward to push the unqualified SMT patches on the conveyor belt body 2, thereby moving the unqualified SMT patches to the outside of the conveyor belt body 2, and the output shaft of the driving motor 20 continues to rotate to drive the first connecting rod 21 and the second connecting rod 24 to rotate backward, and the second connecting rod 24 rotates backward to drive the gear 17 to roll backward, and the gear 17 rolls backward to reset the second rack 18 and the rubber block 19.

[0026] A limiting hole 25 for sliding the second rack 18 is provided on one side of the support plate 11, a limiting rod 26 is fixedly installed inside the limiting hole 25, and a limiting block 27 is fixedly installed on one side of the second rack 18, and the limiting block 27 is slidably connected to the limiting rod 26;

[0027] By setting the second rack 18, the second rack 18 moves forward to drive the limiting block 27 to move forward along the limiting rod 26 inside the limiting hole 25 on the support plate 11. The limiting rod 26 and the limiting block 27 can limit the movement of the second rack 18 to achieve a limiting effect on the second rack 18.

[0028] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6, SMT patch detection equipment, the anti-displacement component 6 includes a plurality of support frames 8, and the plurality of support frames 8 are respectively fixedly mounted on the top surfaces of the two brackets 1. The interior of the support frame 8 is rotatably connected with a movable plate 9, and one side of the movable plate 9 is rotatably connected with one side of the support frame 8 through a bearing. One side of the movable plate 9 is rotatably connected with two fans 10. The other side of the support frame 8 is provided with an adjusting member for adjusting the angle of the movable plate 9. The adjusting member includes a connecting roller 28, and the connecting roller 28 is fixedly mounted on one side of the movable plate 9. One end of the connecting roller 28 passes through the support frame 8 and is fixedly mounted with a ratchet 29. Two latch teeth 30 are installed on one side of the support frame 8. The outer circumferential wall surface of the latch tooth 30 is rotatably connected with the latch tooth 30, and the latch tooth 30 is movably engaged with the ratchet 29. The outer circumferential wall surface of the mounting rod 31 is sleeved with a torsion spring 22, and the latch tooth 30 is elastically connected to the mounting rod 31 through the torsion spring 22;

[0029] Through the provided conveyor belt body 2, the staff places the SMT patch on the top surface of the conveyor belt body 2, and the staff rotates the movable plate 9 and the fan 10 downward to a suitable angle. The movable plate 9 and the fan 10 rotate downward to drive the connecting roller 28 to drive the ratchet 29 to rotate at the same time. The rotation of the ratchet 29 causes the latching tooth 30 to rotate around the mounting rod 31 and twists the torsion spring 22. When the movable plate 9 and the fan 10 are rotated downward to a suitable angle, the middle latching tooth 30 is clamped between the teeth of the ratchet 29 by the torsion spring 22, thereby determining the angle of the ratchet 29, and then determining the angle of the movable plate 9 and the fan 10. The staff starts the fan 10, and the fan 10 rotates to generate airflow, which blows downward onto the SMT patch, thereby using the airflow to press the SMT patch onto the conveyor belt body 2, thereby preventing the SMT patch from shifting on the conveyor belt body 2, and achieving the anti-shifting effect of the SMT patch.
