Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a light inspection machine with rejection function. Background Technology

[0002] Light inspection machines are mainly used for quality inspection of products (commonly found in packaging products of pharmaceuticals, food, and daily chemical products). They use optical and other inspection methods to determine whether the product has foreign objects, appearance defects, or other quality problems. A light inspection machine generally consists of a light inspection box, a light inspection table, a light inspection instrument, and a computer display screen.

[0003] Traditional light inspection machines lack an automatic rejection mechanism, requiring manual removal of defective products, resulting in low efficiency. Furthermore, their fixed structure often leads to a fixed position of the light source. To provide sufficient light to the mechanical system, multiple light sources or more complexly positioned optical reflectors are often needed. Additionally, when inspecting bottles of different heights, workers must constantly adjust the height of the lights to achieve comprehensive and effective inspection of the products, which is cumbersome, wastes manpower, and is inefficient. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a light inspection machine with rejection function, which aims to improve the traditional light inspection machine detection device, which often requires manual rejection of unqualified products and adjustment of light height due to the lack of rejection unit and relatively fixed structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A light inspection machine with rejection function includes a detection device and a rejection unit. A workbench is provided between the detection device and the rejection unit. A conveyor belt for conveying products to be inspected is provided on the workbench. The rejection unit includes a clamping mechanism and a driving mechanism. The driving mechanism is used to drive the clamping mechanism to clamp and reject the products to be rejected. The detection device includes a fixed plate. A rack is fixedly connected inside the fixed plate. A cover is fixedly connected to the bottom wall of the fixed plate. An electric push rod is provided inside the cover. The output end of the electric push rod extends into the fixed plate and is fixedly connected. The system includes a connecting plate with sliding plates connected to both ends. Sliding plates are slidably connected inside a fixed plate. A gear is rotatably connected inside sliding plate one. A toothed block is fixedly connected to the inner side wall of sliding plate one. Sliding plate two is slidably connected inside sliding plate one. A gear two is rotatably connected inside sliding plate two. A rack two is fixedly connected to the outer side wall of sliding plate two. Sliding plate three is slidably connected inside sliding plate two. A toothed block two is fixedly connected to the outer side wall of sliding plate three. A fixed plate two is fixedly connected inside sliding plate three. A light source is fixedly connected to the side wall of fixed plate two.

[0007] As a further description of the above technical solution: the clamping mechanism includes a pneumatic clamp and a lifting electric cylinder for driving the pneumatic clamp to rise and fall. The output end of the pneumatic clamp is provided with two clamping parts, and the clamping parts are provided with semi-cylindrical grooves, and rubber pads are provided in the semi-cylindrical grooves.

[0008] As a further description of the above technical solution: the driving mechanism includes a drive motor and a rotating platform, the inner sidewall of the rotating platform is provided with a gear ring, and the output end of the drive motor is provided with a gear three that meshes with the gear ring.

[0009] As a further description of the above technical solution: the drive motor is a servo motor.

[0010] As a further description of the above technical solution: the rack one and rack two are meshed and connected on the outer wall of the gear one, and the tooth block one and tooth block two are meshed and connected on the outer wall of the gear two.

[0011] As a further description of the above technical solution: a guide plate is provided on the side of the rotating platform.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the mutual cooperation between the electric push rod, connecting plate, sliding plate one, gear one and gear two achieves the effect of freely adjusting the height of the light, which solves the problem that traditional light inspection machine detection devices often have a relatively fixed structure, which often leads to difficulties in lifting and lowering, and requires workers to constantly adjust the height of the light when facing inspection bottles of different heights, thus improving the practicality of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Reference Figure 1-3This utility model provides an embodiment of a light inspection machine with a rejection function, comprising an inspection device and a rejection unit. A workbench 18 is provided between the inspection device and the rejection unit. A conveyor belt 19 for conveying products to be inspected is provided on the workbench 18. The rejection unit includes a clamping mechanism 20 and a driving mechanism 21. The driving mechanism 21 is used to drive the clamping mechanism 20 to clamp and reject the products to be rejected. The inspection device includes a fixed plate 1. A rack 2 is fixedly connected inside the fixed plate 1. A cover 3 is fixedly connected to the bottom wall of the fixed plate 1. An electric push rod 6 is provided inside the cover 3. The output end of the electric push rod 6 extends into the fixed plate 1 and is fixedly connected. A connecting plate 7 is provided, with sliding plates 8 connected to both ends of the connecting plate 7. Sliding plates 8 are slidably connected inside a fixed plate 1. A gear 9 is rotatably connected inside sliding plate 8. A toothed block 10 is fixedly connected to the inner side wall of sliding plate 8. A second sliding plate 11 is slidably connected inside sliding plate 8. A gear 13 is rotatably connected inside sliding plate 11. A rack 12 is fixedly connected to the outer side wall of sliding plate 11. A third sliding plate 14 is slidably connected inside sliding plate 11. A toothed block 15 is fixedly connected to the outer side wall of sliding plate 14. A fixed plate 16 is fixedly connected inside sliding plate 14. A light source 17 is fixedly connected to the side wall of fixed plate 16. The rack 2 and rack 12 are meshed on the outer side wall of gear 9, and the toothed block 10 and toothed block 15 are meshed on the outer side wall of gear 13.

[0022] When the light inspection machine inspects products of different heights, it first activates the electric push rod 6. The output end of the electric push rod 6 causes the connecting plate 7 to move up and down. Then, the movement of the connecting plate 7 causes the sliding plate 8 to move inside the fixed plate 1. The movement of the sliding plate 8 causes the gear 9 to rotate through the rack 2 inside the sliding plate 8. The rotation of the gear 9 then causes the rack 12 to move. The movement of the rack 12 then drives the sliding plate 11 to move. The movement of the sliding plate 11 causes the gear 13 to move through the gear block 10. The sliding plate 11 rotates inside, and the rotation of gear 13 causes gear block 15 to move. The movement of gear block 15 drives sliding plate 14 to move as well. When sliding plate 14 moves, light source 17 moves with it via fixed plate 16, thereby adjusting the height of light source 17. This solves the problem of traditional lamp inspection machines having difficulty in raising and lowering, requiring manual fixing to a certain height and tightening with screws, and not being able to adjust online in real time. The specific height adjustment depends entirely on personal experience, which is extremely inconvenient when changing to inspect products of different specifications.

[0023] The clamping mechanism 20 includes a pneumatic clamp 201 and a lifting electric cylinder 202 for driving the pneumatic clamp 201 to rise and fall. The output end of the pneumatic clamp 201 has two clamping portions 203, each with a semi-cylindrical groove containing a rubber pad. The driving mechanism 21 includes a drive motor 211 and a rotating platform 212. The inner wall of the rotating platform 212 has a gear ring 213, and the output end of the drive motor 211 has a gear 214 that meshes with the gear ring 213. The drive motor 211 is a servo motor. A guide plate is located on the side of the rotating platform 212.

[0024] When a defective product is detected, the lifting electric cylinder 202 drives the air clamp 201 to hold the defective product. Then, the output end of the drive motor 211 drives the gear ring 213 to rotate through the meshing of the gear 214 and the gear ring 213, thereby causing the rotating platform 212 to rotate. Then, the defective product is moved to the guide plate and slides down to the defective product collection point, completing the automatic rejection of the defective product.

[0025] Working principle: When using the lamp inspection machine of this utility model, firstly, start the electric push rod 6. The output end of the electric push rod 6 causes the connecting plate 7 to move up and down. Then, the movement of the connecting plate 7 causes the sliding plate 8 to move inside the fixed plate 1. The movement of the sliding plate 8 causes the gear 9 to rotate inside the sliding plate 8 via the rack 2. Then, the rotation of the gear 9 causes the rack 12 to move. Then, the movement of the rack 12 drives the sliding plate 11 to move. The movement of the sliding plate 11 causes the gear 13 to rotate inside the sliding plate 11 via the tooth block 10. The rotation of the gear 13 causes the tooth block 15 to move. The movement of the tooth block 15 drives the sliding plate 14 to move accordingly. When the sliding plate 14 moves, the light source 17 will move along with the sliding plate 14 via the fixed plate 16, thereby adjusting the height position of the light source 17. When a defective product is detected, the lifting electric cylinder 202 drives the air clamp 201 to hold the defective product. Then, the output end of the drive motor 211 drives the gear ring 213 to rotate through the meshing of the gear 214 and the gear ring 213, thereby causing the rotating platform 212 to rotate. Then, the defective product is moved to the guide plate and slides down to the defective product collection point.

[0026] This invention achieves automatic adjustment of the light source height by setting up a detection device, thus improving the practicality of the light inspection machine; by setting up a rejection unit, unqualified products are directly rejected without manual operation, which greatly improves the working efficiency of the light inspection machine and saves labor costs.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
