Description

Technical Field

[0001] This invention relates to the field of packaging inspection technology, and in particular to an external material self-rotating light inspection device. Background Technology

[0002] For liquid products with high quality requirements, such as injectable solutions and nutrient solutions, comprehensive testing of the liquid in the bottle is often necessary to avoid impurities and flocculation caused by product deterioration. Current technology generally uses visual inspection to detect these impurities in liquid products. However, small impurities in liquids tend to settle, and flocculation is similar in color to the liquid itself, making it easy to miss if the product is stationary. To accurately detect these impurities and floating flocculation, the liquid needs to be in motion. Conversely, to detect defects in the bottle itself, such as markings or flaws, the bottle needs to be stationary before reaching the camera. Therefore, the product must undergo a series of high-speed rotations and braking operations before entering visual inspection. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an external material rotation lamp inspection device that can realize continuous conveying, rotation, braking, detection, and rejection. It has high detection accuracy, high detection efficiency, simple structure, and is economical and practical.

[0004] This invention is achieved through the following technical solution: An external material rotation light inspection device includes a frame and a material conveying mechanism, a material rotation drive mechanism, a material braking mechanism, and a follow-up imaging mechanism mounted on the frame. The material conveying mechanism includes a material turntable and a material bottom mold assembly. A plurality of material bottom mold assemblies are evenly spaced and arranged in the circumferential direction of the material turntable and rotate with the material turntable. Each material bottom mold assembly includes a bottom mold, a drive wheel, and a first synchronous belt assembly. The bottom mold is used to place and position the product to be inspected. The drive wheel drives the plurality of bottom molds to rotate through the first synchronous belt assembly. A plurality of material rotation drive mechanisms are fixedly arranged on the frame near the outer periphery of the material turntable. When a material bottom mold assembly passes by, it drives the drive wheel on the material bottom mold assembly to rotate, thereby driving the bottom mold on the material bottom mold assembly to rotate.

[0005] The material braking mechanism includes a cam plate, a cam roller, a first mounting bracket, a connecting rod, a brake block, and a first spring. The cam plate is fixed to the frame and located at the position of the material rotation drive mechanism. One cam plate is correspondingly provided for each set of material rotation drive mechanisms. The cam plate has a contour that matches the movement trajectory of the cam roller. The middle part of the connecting rod is rotatably mounted on the material turntable near the material bottom mold assembly via the first mounting bracket. One connecting rod is correspondingly provided for each set of material bottom mold assemblies. The connecting rod can rotate with the material turntable. The cam roller is located at one end of the connecting rod. The brake block is located at the other end of the connecting rod and is opposite to the drive wheel. The first spring passes through the connecting rod, with one end abutting against the brake block and the other end abutting against the first mounting bracket. When the cam roller reaches the cam plate and rolls on the contour of the cam plate, the cam roller drives the connecting rod to swing, thereby driving the brake block to move away from the drive wheel to disengage from the drive wheel, so that the drive wheel can drive the product to rotate. The first spring is compressed. When the cam roller disengages from the cam plate, the brake block is reset under the action of the elastic force of the first spring to press against the drive wheel, thereby braking the rotating bottom mold.

[0006] The follow-up shooting mechanism is located on the side of the material turntable. The follow-up shooting mechanism includes a follow-up frame and several shooting components mounted on the follow-up frame. The number of shooting components is equal to the number of material rotation drive mechanisms. The shooting components are used to perform follow-up shooting inspection on the product after it has rotated and braked on the material bottom mold assembly.

[0007] Furthermore, the connecting rod includes a first arm and a second arm that are L-shaped to each other. The middle part of the first arm is rotatably mounted on the first mounting bracket, which is fixed on the material turntable. A cam roller is disposed at the end of the first arm, and the brake block is disposed at the end of the second arm via a first spring.

[0008] Furthermore, the profile on the cam includes a guide section and an arc section that are sequentially arranged and connected to each other along the rotation direction of the material turntable. The guide section extends obliquely from the inside to the outside, and the arc section is opposite to the material self-rotation drive mechanism, with its center coinciding with the center of the material turntable.

[0009] Furthermore, the drive wheel is a transmission wheel with meshing teeth, and the front end of the brake block is provided with a protruding ridge that can cooperate with the tooth groove of the drive wheel. The brake block brakes the drive wheel by the engagement of the protruding ridge with the tooth groove.

[0010] Furthermore, the first synchronous belt assembly includes a first driving pulley, a first driven pulley, a first synchronous belt, and a first tensioning pulley. The first synchronous belt is a double-toothed synchronous belt. The first driving pulley is driven and connected to several first driven pulleys through the first tensioning pulley and the first synchronous belt. Each first driving pulley and first driven pulley is provided with a bottom mold. The first driving pulley is coaxially arranged with the drive pulley. The first tensioning pulley is mounted on a second mounting plate. The second mounting plate is provided with a second elongated slot. The second mounting plate is fixedly mounted on the material pallet through the second elongated slot, and its mounting position is adjusted through the second elongated slot.

[0011] Furthermore, the material rotation drive mechanism includes a first servo motor and a second synchronous belt assembly. The second synchronous belt assembly includes a second driving wheel, a second driven wheel, and a second synchronous belt. The first servo motor is driven and connected to the second driving wheel. The second synchronous belt is a double-tooth synchronous belt. The second driving wheel is driven and connected to several second driven wheels through the second synchronous belt. The second synchronous belt meshes with the drive wheel to drive the drive wheel to rotate.

[0012] Furthermore, the second synchronous belt assembly also includes a tensioning buffer mechanism, which includes a second tensioning wheel and an elastic adjustment mounting bracket. The elastic adjustment mounting bracket includes a fixed base, a mounting base, a connecting rod, and a second spring. The fixed base is fixedly installed, one end of the connecting rod is connected to the fixed base, and the mounting base is installed at the other end of the connecting rod via the second spring. The second tensioning wheel is rotatably installed on the mounting base and adjusts the tension of the second synchronous belt via the second spring.

[0013] Furthermore, the material conveying mechanism also includes a bottle pressing turntable disposed above the material turntable. The bottle pressing turntable is evenly provided with a plurality of bottle pressing rods in the circumferential direction, and the bottle pressing rods correspond one-to-one with the bottom mold on the material turntable, which are used to press the product on the bottom mold from above to ensure the stability of the product when it rotates at high speed.

[0014] Furthermore, the follower frame is arranged in an arc shape around the material turntable, with the center of the turntable as its center. The follower frame is connected to a follower drive component, which includes a second servo motor, a gear, and a rack. The second servo motor is driven by the gear, and the rack is set on the follower frame with the center of the material turntable as its center. The rack meshes with the gear, and the second servo motor drives the rack to swing through the gear, which in turn drives the follower frame to swing. Several shooting components on the follower frame swing accordingly, and the swing speed is adapted to the speed of the material tray so that the shooting components can move with the product to take pictures. One set of shooting components follows one set of material base mold components.

[0015] Furthermore, it also includes a feed plate chain, a bottle inlet screw, a bottle inlet star wheel assembly, and a bottle outlet star wheel assembly. The feed plate chain is used to transport the product to be tested. The outlet end of the feed plate chain is connected to the inlet end of the bottle inlet screw. The outlet end of the bottle inlet screw is connected to the inlet end of the bottle inlet star wheel assembly. The outlet end of the bottle inlet star wheel assembly is connected to the inlet end of the material turntable. The outlet end of the material turntable is connected to the bottle outlet star wheel assembly. The bottle outlet star wheel assembly includes a qualified product star wheel and an NG product star wheel. The qualified product star wheel is used to transport qualified products outward, and the NG product star wheel is used to transport unqualified products outward.

[0016] This invention comprises a material conveying mechanism, a material rotation drive mechanism, a material braking mechanism, a follow-up imaging mechanism, a feeding plate chain, a bottle inlet screw, a bottle inlet star wheel assembly, and a bottle outlet star wheel assembly, achieving continuous automatic conveying, rotation, braking, detection, and discharging of liquid products. The material rotation drive mechanism is fixedly mounted outside the material turntable, driving the bottom mold module of the material to rotate there. Compared to methods where the drive mechanism is mounted on the material turntable, it can run its wiring outside the turntable, eliminating the need for an electric slip ring structure on the material conveying mechanism, thus avoiding entanglement issues, saving costs, and simplifying the structure. The material braking mechanism uses a cam structure, allowing the product to be braked as it rotates with the material turntable, eliminating the need for additional power drive and further simplifying the structure. Both the mechanism and the material braking mechanism are driven and braked by drive wheels connected to the synchronous belt assembly. The rotation and braking of the drive wheels cause several bottom molds to rotate and brake simultaneously, enabling rapid rotation and braking of the product. Compared with braking the bottom molds by friction, the braking is faster and more sensitive, bringing the high-speed rotating bottles to an immediate stop. It also keeps the products on each bottom mold in a state of synchronous rotation and stillness, improving the accuracy of product inspection. The follow-up shooting mechanism is set opposite to the material rotation drive mechanism, and can follow and shoot the products after they have rotated and braked. The material turntable can rotate continuously, improving the accuracy and efficiency of inspection. The bottle discharge star wheel assembly is equipped with a qualified product star wheel and an NG product star wheel to classify and discharge the inspected products, realizing the integration of inspection and rejection.

Detailed Implementation

[0032] An external material self-rotating light inspection device, such as Figures 1 to 6 As shown, the device includes a frame 1 and a material conveying mechanism 2, a material rotation drive mechanism 3, a material braking mechanism 4, and a follow-up shooting mechanism 6 mounted on the frame 1. The material conveying mechanism 2 includes a material turntable 21 and a material bottom mold assembly 22. Several material bottom mold assemblies 22 are evenly spaced in the circumferential direction of the material turntable 21 and rotate with the material turntable 21. The material turntable 21 is equipped with corresponding power drive components, such as a servo motor that drives the turntable spindle to rotate.

[0033] like Figures 7 to 9 Each material bottom mold assembly 22 includes a bottom mold 221, a drive wheel 223, and a first synchronous belt 2223 assembly 222. The bottom mold 221 is used to place and position the product 5 to be tested, with one bottom mold 221 corresponding to one product 5. The drive wheel 223 drives several bottom molds 221 to rotate via the first synchronous belt 2223 assembly 222, thereby causing the product 5 to rotate. Several material rotation drive mechanisms 3 are fixedly arranged on the frame 1 near the outer periphery of the material turntable 21, and are used to drive the drive wheel 223 on the material bottom mold assembly 22 to rotate when the material bottom mold assembly 22 passes by, thereby causing the bottom mold 221 on the material bottom mold assembly 22 to rotate.

[0034] The material braking mechanism 4 includes a cam plate 41, a cam roller 43, a first mounting bracket 47, a connecting rod 44, a brake block 45, and a first spring 46. The cam plate 41 is fixed on the frame 1 and located at the position of the material rotation drive mechanism 3. One cam plate 41 is correspondingly provided for each set of material rotation drive mechanisms 3. The cam plate 41 has a contour that matches the movement trajectory of the cam roller 43. The middle part of the connecting rod 44 is rotatably mounted on the material turntable 21 near the material bottom mold assembly 22 via the first mounting bracket 47. One connecting rod 44 is correspondingly provided for each set of material bottom mold assemblies 22. The connecting rod 44 can rotate with the material turntable 21. The cam roller 43 is located at one end of the connecting rod 44. Brake block 45 is disposed at the other end of the connecting rod 44 and is opposite to the drive wheel 223. When the cam roller 43 reaches the cam plate 41 and rolls on the contour of the cam plate 41, the cam roller 43 drives the connecting rod 44 to swing, thereby driving the brake block 45 to move away from the drive wheel 223 to disengage from the drive wheel 223, so that the drive wheel 223 can drive the product to rotate at high speed. The first spring 46 passes through the connecting rod 44, with one end abutting against the brake block 45 and the other end abutting against the first mounting bracket 47. When the cam roller 43 disengages from the cam plate 41, the brake block 45 resets under the elastic force of the first spring 46 to press the drive wheel 223, thereby braking the rotating bottom mold 221. When the product 5 is braked, its bottle body stops rotating, the first spring 46 is compressed, and the liquid in the bottle continues to move under inertia, so as to facilitate the detection of impurities. The brake block 45 acts on the drive wheel 223, which in turn drives the product to rotate synchronously and brake through the first synchronous belt 2223 assembly 222, so that the rotation angle of the product 5 is consistent, which can improve the accuracy of detection.

[0035] The follow-up shooting mechanism 6 is located beside the material turntable 21. The follow-up shooting mechanism 6 includes a follow-up frame 61 and a plurality of shooting components 62 disposed on the follow-up frame 61. The number of shooting components 62 is equal to the number of material self-rotation drive mechanisms 3. The shooting components 62 are used to perform follow-up shooting detection on the product 5 after it has rotated and braked on the material bottom mold assembly 22. This can realize continuous conveying and detection of the product, and the material turntable 21 does not need to stop intermittently.

[0036] As one implementation method, such as Figure 10 , Figure 11 The connecting rod 44 includes a first arm 441 and a second arm 442 that are L-shaped to each other. The middle part of the first arm 441 is rotatably mounted on a first mounting bracket 47, which is fixed on the material turntable 21. A cam roller 43 is disposed at the end of the first arm 441, and the brake block 45 is disposed at the end of the second arm 442 by a first spring 46.

[0037] The upper contour of the cam plate 41 must be designed according to the movement trajectory of the brake block 45, and must be compatible with the diameter of the light inspection machine turntable, the size of the connecting rod 44, and the stroke of the brake block 45. In this embodiment, for example... Figure 14 The profile on the cam includes a guide section 411 and an arc section 412 that are sequentially arranged and interconnected along the rotation direction of the material turntable 21. The guide section 411 extends obliquely from the inside to the outside, and the arc section 412 is opposite to the material rotation drive mechanism 3, with its center coinciding with the center of the material turntable 21. The cam roller 43 slides from the guide section 411 to the arc section 412. When the material rotation drive mechanism 3 drives the drive wheel 223 and the bottom mold 221 to rotate, the cam roller 43 transitions from the guide section 411 to rolling on the arc section 412 on the cam plate 41. Figure 10 The first arm 441 of the connecting rod 44 swings at a certain angle under the action of the cam roller 43, causing the second arm 442 of the connecting rod 44 to move away from the drive wheel 223. The brake block 45 does not contact the drive wheel 223, and the bottom mold 221 rotates at high speed. At the same time, due to the swing of the connecting rod 44, the first spring 46 is compressed. As the material bottom mold assembly 22 rotates with the material turntable 21, such as Figure 11 The drive wheel 223 disengages from the material rotation drive mechanism 3, the cam roller 43 disengages from the cam plate 41, and the restoring force of the first spring 46 causes the connecting rod 44 to reset. The first arm 441 of the connecting rod 44 stands upright, driving the second arm 442 to approach the drive wheel 223 until the brake block 45 on the second arm 442 contacts the drive wheel 223 and presses the drive wheel 223 under the elastic force of the first spring 46 to brake.

[0038] To better achieve braking of the drive wheel 223, in this embodiment, the drive wheel 223 is a pulley, that is, a transmission wheel with meshing teeth, such as... Figure 12 The front end of the brake block 45 is provided with a protruding ridge 451 that can cooperate with the tooth groove of the drive wheel 223. The brake block 45 brakes the drive wheel 223 by the engagement of the protruding ridge 451 with the tooth groove.

[0039] In this embodiment, as Figure 9The first synchronous belt 2223 assembly 222 includes a first driving pulley 2221, a first driven pulley 2222, a first synchronous belt 2223, and a first tensioning pulley 2224. The first synchronous belt 2223 is a double-sided toothed synchronous belt. The first driving pulley 2221 is driven and connected to several first driven pulleys 2222 via the first tensioning pulley 2224 and the first synchronous belt 2223. Each first driving pulley 2221 and each first driven pulley 2222 is provided with a bottom mold 221. The first driving pulley 2221 is coaxially arranged with the drive pulley 223, and the drive pulley 223 drives the first driving pulley 2221 to rotate. Multiple bottom molds 221 can be provided on a set of material bottom mold assemblies 22, allowing for simultaneous driving, rotation, braking, and detection of multiple products. The first tensioning pulley 2224 is mounted on the second mounting plate 224. The second mounting plate 224 is provided with a second elongated slot 2241. The second mounting plate 224 is fixedly mounted on the material pallet through the second elongated slot 2241, and its installation position is adjusted through the second elongated slot 2241, thereby adjusting the tension of the first synchronous belt 2223.

[0040] As one implementation method, such as Figure 8 The material rotation drive mechanism 3 includes a first servo motor 33 and a second synchronous belt assembly 32. The second synchronous belt assembly 32 includes a second driving pulley 321, a second driven pulley 322, and a second synchronous belt 323. The first servo motor 33 is drivenly connected to the second driving pulley 321. The second synchronous belt 323 is a double-tooth synchronous belt. The second driving pulley 321 is drivenly connected to several second driven pulleys 322 through the second synchronous belt 323. The second synchronous belt 323 meshes with the drive wheel 223 to drive the drive wheel 223 to rotate.

[0041] In this embodiment, the second synchronous belt assembly 32 further includes a tensioning and buffering mechanism 324. The tensioning and buffering mechanism 324 includes a second tensioning wheel 3241 and an elastic adjustment mounting bracket. The elastic adjustment mounting bracket includes a fixed base 3244, a mounting base 3242, a connecting rod 3243, and a second spring. The fixed base 3244 is fixedly installed. One end of the connecting rod 3243 is connected to the fixed base 3244. The mounting base 3242 is mounted on the other end of the connecting rod 3243 via the second spring. The second tensioning wheel 3241 is rotatably mounted on the mounting base 3242. The position of the second tensioning wheel 3241 can be adjusted by the second spring, thereby adjusting the tension of the second synchronous belt 323 and providing tensioning and buffering effects on the second synchronous belt 323. The second tensioning wheel 3241 is located on the outer side of the second synchronous belt 323.

[0042] To achieve a reasonable spatial layout, in this embodiment, as follows: Figure 13The material rotation drive mechanism 3 is mounted on the frame 1 via a second mounting bracket. The second mounting bracket includes a third mounting plate 31 and two support columns 34. The two support columns 34 are located at the bottom of the third mounting plate 31 and support the frame 1 to support the material rotation drive mechanism 3. The first servo motor 33 is mounted at the bottom of the third mounting plate 31, and the second synchronous belt assembly 32 is located at the top of the third mounting plate 31. An outer cover 35 may also be provided on the second mounting bracket to enclose the material rotation drive mechanism 3.

[0043] In order to adjust the installation position of the cam plate 41 and adapt to the adjustment of the braking force of the drive wheel 223, in this embodiment, the cam plate 41 is fixed on the first mounting plate 42. The first mounting plate 42 is provided with a first elongated slot 421. The first mounting plate 42 is fixedly installed on the bottom of the third mounting plate 31 through the first elongated slot 421. The cam plate 41 adjusts its installation position through the first elongated slot 421.

[0044] In this embodiment, as Figure 2 , Figure 3 The material conveying mechanism 2 also includes a bottle-pressing turntable 23 disposed above the material turntable 21. The bottle-pressing turntable 23 has a plurality of bottle-pressing rods 24 evenly arranged circumferentially, and each bottle-pressing rod 24 corresponds one-to-one with a bottom mold 221 on the material turntable 21. These rods are used to press the product on the bottom mold 221 from above, ensuring the stability of the product during high-speed rotation. The bottle-pressing rods 24 are connected to a lifting drive mechanism to cooperate with the bottom mold 221 in pressing the product.

[0045] In this embodiment, the follower frame 61 is arranged in an arc shape around the material turntable 21 with the center of the turntable as the center. The follower frame 61 is connected to a follower drive component, which includes a second servo motor, a gear and a rack (not shown in the figure). The second servo motor is driven by the gear. The rack is arranged on the follower frame 61 with the center of the material turntable 21 as the center. The rack meshes with the gear. The second servo motor drives the rack to swing through the gear, which in turn drives the follower frame 61 to swing. Several shooting components 62 on the follower frame 61 swing accordingly. The swing speed is adapted to the speed of the material tray so that the shooting components 62 can move with the product to take pictures. A group of shooting components 62 follows a group of material bottom mold components 22.

[0046] like Figures 1 to 3The present invention also includes a feed plate chain 7, a bottle inlet screw 8, a bottle inlet star wheel assembly 9, and a bottle outlet star wheel assembly 10. The feed plate chain 7 is used to transport the product to be tested. The outlet end of the feed plate chain 7 is connected to the inlet end of the bottle inlet screw 8. The outlet end of the bottle inlet screw 8 is connected to the inlet end of the bottle inlet star wheel assembly 9. The outlet end of the bottle inlet star wheel assembly 9 is connected to the inlet end of the material turntable 21. The outlet end of the material turntable 21 is connected to the bottle outlet star wheel assembly 10. The bottle outlet star wheel assembly 10 includes a qualified product star wheel 11 and an NG (Not Good) product star wheel. The qualified product star wheel 11 is used to transport qualified products outward, and the NG product star wheel 12 is used to transport unqualified products outward. After the product passes through the feeding plate chain 7, the bottle feeding screw 8, and the bottle feeding star wheel assembly 9 in sequence, it reaches the bottom mold 221 of the material turntable 21. As the material turntable 21 rotates, it is driven to rotate when passing through the material rotation drive mechanism 3. When it leaves the material rotation drive mechanism 3, the product bottle is braked, but the internal liquid continues to move. The follow-up shooting mechanism 6 follows and shoots the detection. After the detection is completed, it is output by the bottle exit star wheel assembly 10. Qualified products are output by the qualified product star wheel 11, and unqualified products are output by the NG product star wheel 12.

[0047] The above detailed description is a specific description of feasible embodiments of the present invention. These embodiments are not intended to limit the patent scope of the present invention. All equivalent implementations or modifications that do not depart from the present invention should be included in the patent scope of this case.
