Description

Technical Field

[0001] This utility model relates to the field of conveying technology, and in particular to a conveying mechanism for a labeling machine. Background Technology

[0002] In the field of surface labeling of electronic components, precision parts and other products, fully automated labeling equipment has been widely used in mass production scenarios. It achieves rapid labeling through mechanical positioning and standardized processes. In existing technologies, products are generally transported to preset labeling stations by a conveyor mechanism.

[0003] However, it's worth considering that when products are transported from the previous process to the labeling station, there is a random error between the actual position of the product and its theoretically preset position. This error can lead to inaccurate labeling, severely affecting the product's appearance and quality. This is especially true for small products such as electronic components and precision parts, as it can reduce the labeling yield and fail to meet labeling requirements.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a conveying mechanism for a labeling machine to solve the problem that there is a random error between the actual position of the product at the labeling station and the theoretical preset position, which leads to inaccurate labeling position.

[0006] To achieve the above objectives, this utility model provides a conveying mechanism for a labeling machine, including a frame and a conveyor belt, wherein the frame is provided with a driver for driving the conveyor belt to move;

[0007] A support frame is provided above the conveyor belt. The support frame is equipped with a correction structure for correcting the position of the product. The frame is equipped with an adjustment component for adjusting the horizontal position of the support frame. The frame is also equipped with a positioning stop structure for positioning the product.

[0008] Preferably, the correction structure includes a guide column fixedly installed on a support frame, two correction plates slidably sleeved on the outside of the guide column, two rectangular holes opened on the support frame, a fixing column fixedly connected to the top of the correction plate and passing through the corresponding rectangular hole, a compression spring sleeved on the outside of the guide column and the two ends of the compression spring being fixedly connected to the two correction plates respectively, and a pusher for pushing the fixing column to move on the support frame.

[0009] Preferably, the pushing component includes a first hydraulic telescopic rod fixedly installed on the support frame, a movable plate is provided above the support frame, and the telescopic end of the first hydraulic telescopic rod is fixedly connected to the movable plate. Push plates are fixedly connected to both ends of the movable plate, and the push plates are inclined. The sides of the two push plates that are close to each other are in contact with two fixed columns.

[0010] Preferably, the adjusting component includes two first sliders fixedly installed on the support frame, and the two first sliders are slidably installed on both sides of the frame. Each side of the frame is provided with a pressing plate, and a plurality of second hydraulic telescopic rods are fixedly connected to each side of the frame. The telescopic ends of the second hydraulic telescopic rods are fixedly connected to the corresponding pressing plates, and the side of the first slider away from the frame is in contact with the pressing plate.

[0011] Preferably, the positioning and stopping structure includes stop plates respectively disposed on both sides of the support frame, a second slider is provided on both sides of the stop plate, and two adjacent second sliders are slidably connected to both sides of the frame, a third hydraulic telescopic rod is fixedly connected to the second slider, and the telescopic end of the third hydraulic telescopic rod is fixedly connected to the stop plate, and the side of the second slider away from the frame is in contact with the pressing plate.

[0012] Preferably, the frame is provided with several mounting brackets below, and two third sliders are fixedly connected to the top of the mounting brackets. Two adjacent third sliders are slidably mounted on both sides of the frame, and the side of the third slider away from the frame is in contact with the pressing plate.

[0013] Preferably, the driver includes a servo motor fixedly mounted on a frame, the output end of the servo motor being fixedly connected to a first synchronous pulley, two support rollers cooperating with a conveyor belt being rotatably connected to the frame, one of the support rollers being fixedly connected to a second synchronous pulley, the first synchronous pulley and the second synchronous pulley being connected by a synchronous belt, a protective shell being fixedly connected to the frame, and the first synchronous pulley and the second synchronous pulley being located inside the protective shell.

[0014] The beneficial effects of this utility model are as follows: The conveyor belt is driven by a driver to transport the product. When the product is about to move to the labeling station, the positioning and stopping structure positions the product so that it is stationary relative to the frame. Then, the straightening structure corrects the position of the product on the conveyor belt so that the product is centered relative to the conveyor belt. After the product is corrected, the positioning and stopping structure releases the product's positioning. The driver then drives the product to move to the labeling station again via the conveyor belt. Before the product moves to the labeling station, its position is corrected so that the position and angle of each product entering the labeling station are unified to a fixed reference position that is completely aligned with the coordinate system of the labeling head. This greatly improves the absolute accuracy and consistency of labeling and further increases the labeling yield. Attached Figure Description

[0025] This specification provides one or more embodiments of a conveying mechanism for a labeling machine, such as... Figure 1 As shown, it includes a frame 1 and a conveyor belt 2, and the frame 1 is equipped with a driver for driving the conveyor belt 2 to move.

[0026] A support frame 5 is provided above the conveyor belt 2. The support frame 5 is equipped with a correction structure for correcting the product position. The frame 1 is equipped with an adjustment component for adjusting the horizontal position of the support frame 5 and a positioning stop structure for positioning the product. The conveyor belt 2 is driven by a driver to move and transport the product. When the product is about to move to the labeling station, the positioning stop structure positions the product so that the product is stationary relative to the frame 1. Then, the correction structure corrects the position of the product on the conveyor belt 2 so that the product is centered relative to the conveyor belt 2. After the product correction is completed, the positioning stop structure releases the product positioning, and the driver drives the product to move to the labeling station again via the conveyor belt 2. Before the product moves to the labeling station, the position of the product is corrected so that the position and angle of each product when entering the labeling station are unified to a fixed reference position that is completely aligned with the coordinate system of the labeling head. This greatly improves the absolute accuracy and consistency of labeling and further improves the labeling yield.

[0027] In embodiments of this utility model, such as Figure 1 and Figure 3As shown, the correction structure includes a guide post 12 fixedly installed on a support frame 5. Two correction plates 3 are slidably sleeved on the outside of the guide post 12. Two rectangular holes 7 are opened on the support frame 5. A fixing post 8 is fixedly connected to the top of the correction plate 3, and the fixing post 8 passes through the corresponding rectangular hole 7. A compression spring 13 is sleeved on the outside of the guide post 12, and the two ends of the compression spring 13 are fixedly connected to the two correction plates 3 respectively. The support frame 5 is provided with a pushing component for moving the fixing post 8. The pushing component includes a first hydraulic telescopic rod 11 fixedly installed on the support frame 5. A movable plate 9 is provided above the support frame 5, and the telescopic end of the first hydraulic telescopic rod 11 is fixedly connected to the movable plate 9. The two ends of the movable plate 9 are fixedly... A push plate 10 is connected and is inclined. The two push plates 10 are in contact with two fixed posts 8 on their adjacent sides. The compression spring 13 is initially in a compressed state. The compression spring 13 applies a pushing force to the straightening plate 3 so that the fixed post 8 is in close contact with the push plate 10. The first hydraulic telescopic rod 11 drives the movable plate 9 and the push plate 10 to move, so that the push plate 10 pushes the fixed post 8 to slide relative to the rectangular hole 7. The fixed post 8 can then drive the straightening plate 3 to move, so that the two straightening plates 3 move towards the product at the same time. Finally, the two straightening plates 3 straighten and center the product. When the first hydraulic telescopic rod 11 drives the movable plate 9 to move in the opposite direction, the compression spring 13 can drive the straightening plate 3 to no longer contact the product.

[0028] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the adjusting component includes two first sliders 6 fixedly mounted on the support frame 5, and the two first sliders 6 are slidably mounted on both sides of the frame 1. Pressing plates 14 are provided on both sides of the frame 1. Several second hydraulic telescopic rods 15 are fixedly connected to both sides of the frame 1, and the telescopic ends of the second hydraulic telescopic rods 15 are fixedly connected to the corresponding pressing plates 14. The side of the first slider 6 away from the frame 1 contacts the pressing plate 14. The positioning and stopping structure includes stopping plates 4 respectively provided on both sides of the support frame 5. Second sliders 16 are provided on both sides of the stopping plates 4, and two adjacent second sliders 16 are slidably connected to both sides of the frame 1. A third hydraulic telescopic rod 17 is fixedly connected to the second slider 16, and the telescopic end of the third hydraulic telescopic rod 17 is fixedly connected to the stop plate 4. The side of the second slider 16 away from the frame 1 is in contact with the pressing plate 14. Several mounting brackets 18 are provided below the frame 1. Two third sliders 19 are fixedly connected to the top of the mounting brackets 18, and two adjacent third sliders 19 are slidably mounted on both sides of the frame 1. The side of the third slider 19 away from the frame 1 is in contact with the pressing plate 14. The operator can change the initial position of the support frame 5 relative to the frame 1 by driving the first slider 6 to slide relative to the frame 1 through the support frame 5. The operator can also drive the second slider 16 to slide relative to the frame 1. Sliding the frame 1 changes the initial position of the stop plate 4. The operator drives the third slider 19 to slide relative to the frame 1, changing the initial position of the mounting bracket 18. The second hydraulic telescopic rod 15 drives the pressing plate 14 to move, pressing the first slider 6, second slider 16, and third slider 19, thus fixing them relative to the frame 1. The frame 1 is then fixed in the preset position by the mounting bracket 18. The third hydraulic telescopic rod 17 drives the stop plate 4, located on the side of the support frame 5 away from the labeling station, to move upwards. The conveyor belt 2 drives the product from the moved stop plate 4. When the product moves from below to the side of another stop plate 4, the stop plate 4 located on the side of the support frame 5 facing the labeling station positions the product so that the product is stationary relative to the frame 1. At this time, the stop plate 4 located on the side of the support frame 5 away from the labeling station is driven to move down by the third hydraulic telescopic rod 17. The stop plate 4 located on the side of the support frame 5 away from the labeling station blocks the next product from moving to the bottom of the support frame 5. When the straightening structure has corrected the position of the product, the stop plate 4 located on the side of the support frame 5 facing the labeling station can be driven to move up by the third hydraulic telescopic rod 17, and the product can move from below the moved stop plate 4 to the labeling station.

[0029] In embodiments of this utility model, such as Figure 1 and Figure 2As shown, the driver includes a servo motor 20 fixedly mounted on the frame 1. The output end of the servo motor 20 is fixedly connected to a first synchronous pulley 21. Two support rollers 22 that cooperate with the conveyor belt 2 are rotatably connected to the frame 1. A second synchronous pulley 23 is fixedly connected to one of the support rollers 22. The first synchronous pulley 21 and the second synchronous pulley 23 are connected by a synchronous belt 24. A protective shell 25 is fixedly connected to the frame 1, and the first synchronous pulley 21 and the second synchronous pulley 23 are located inside the protective shell 25. The servo motor 20 drives the first synchronous pulley 21 to rotate, and the first synchronous pulley 21 drives the second synchronous pulley 23 and the support roller 22 to rotate through the synchronous belt 24. The support roller 22 can then drive the product to move through the conveyor belt 2. The design of the protective shell 25 protects the first synchronous pulley 21 and the second synchronous pulley 23.
