Furthermore, by utilizing the spring force, the push plate can slide in the opposite direction under the action of the spring force when the cam is not abutting the abutment plate. This allows the push plate in the detection frame to push the defective products on the conveyor belt, thereby enabling the defective products to pass through the discharge port opened on the detection frame and be removed from the conveyor belt.

[0013] Preferably, a support plate is fixedly installed on the detection frame, and the output shaft is rotatably mounted on the support plate.

[0018] The aforementioned components achieve the following effect: by utilizing the detection probe, the detection probe can detect defective products on the conveyor belt, and the detected defective products can be removed by the push plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a drive assembly to control the sliding of a push plate within the detection frame, thereby enabling the push plate to push defective products on the conveyor belt.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a defective product sorting device for an SMT production line, including a base 1, a conveyor belt 2 mounted on the base 1, and a detection frame 3 fixedly mounted on the base 1. A discharge port 5 is provided on one side of the detection frame 3, and a push plate 15 is provided inside the detection frame 3, which is slidably disposed within the detection frame 3 via a drive assembly. The push plate 15 is positioned on the conveyor belt 2. By controlling the sliding of the push plate 15 in the detection frame 3 using the drive assembly, the push plate 15 can push the defective products on the conveyor belt 2, allowing the defective products to pass through the discharge port 5 on the detection frame 3 and thus be removed from the conveyor belt 2, thereby improving the practicality of the entire device.

[0024] The following is a detailed explanation of its overall setup and function.

[0025] The drive assembly includes a connecting rod 14 slidably disposed on the other side of the detection frame 3, and a push plate 15 fixedly mounted on one end face of the connecting rod 14. By utilizing the connecting rod 14, the connecting rod 14 can reciprocate under the action of the drive assembly, thereby driving the push plate 15 in the detection frame 3 to reciprocate during the sliding process, so that the sliding of the push plate 15 can remove defective products from the conveyor belt 2.

[0026] The drive assembly includes a bracket 6 fixedly mounted on the detection frame 3. A motor 7 is fixedly mounted on the bracket 6. An output shaft 8 is fixedly mounted on the output end of the motor 7. A cam 10 is fixedly mounted on the other end of the output shaft 8. A connecting plate 13 is fixedly mounted on the other end of the connecting rod 14. An abutment plate 11 that abuts against the cam 10 is fixedly mounted on the connecting plate 13. By utilizing the motor 7, the output shaft 8 can rotate under the action of the motor 7, thereby allowing the cam 10 to slide through the abutment plate 11, thus causing the push plate 15 in the connecting frame to slide.

[0027] Multiple elastic elements 12 are provided between the abutment plate 11 and the detection frame 3. Each elastic element 12 is a spring, with one end of the spring fixedly connected to the detection frame 3 and the other end fixedly connected to the abutment plate 11. By utilizing the spring, the abutment plate 11 can slide against the spring force during the process of the cam 10 abutting against the abutment plate 11. Furthermore, by utilizing the spring force, the push plate 15 can slide in the opposite direction under the action of the spring force when the cam 10 is not abutting against the abutment plate 11. This allows the push plate 15 in the detection frame 3 to push the defective products on the conveyor belt 2, thereby allowing the defective products to pass through the discharge port 5 opened on the detection frame 3 and be removed from the conveyor belt 2.

[0028] A support plate 9 is fixedly mounted on the detection frame 3, and the output shaft 8 is rotatably mounted on the support plate 9. By utilizing the support plate 9, the output shaft 8 is provided with auxiliary support, thereby improving the stability of the cam 10 during rotation.

[0029] A protective pad 16, which is a rubber pad, is fixedly installed on the push plate 15. By using the rubber pad, it can protect defective products.

[0030] A detection probe 4 is fixedly installed on the top surface of the detection frame 3, and the detection probe 4 is located above the push plate 15. By using the detection probe 4, the detection probe 4 can detect defective products on the conveyor belt 2, and the push plate 15 can remove the detected defective products.

[0031] Working principle: The conveyor belt 2 on the base 1 is used to transport the products, and the detection probe 4 on the detection frame 3 can detect defective products on the conveyor belt 2. When the detection probe 4 detects a defective product, the motor 7 is activated. It is worth noting that a sensor should be installed between the detection probe 4 and the motor 7. This allows the detection probe 4 to start and stop the motor 7 when it detects a defective product on the conveyor belt 2. The output shaft 8 rotates under the action of the motor 7, causing the cam 10 to abut against the abutment plate 11. Using a spring, the abutment plate 11 slides against the spring force during the contact process. Furthermore, the spring force allows the push plate 15 to slide in the opposite direction when the cam 10 is not in contact with the abutment plate 11. This push plate 15 in the detection frame 3 pushes the defective product on the conveyor belt 2, allowing it to pass through the discharge port 5 on the detection frame 3 and be removed from the conveyor belt 2.
