Description

Technical Field

[0001] This invention relates to the field of self-adhesive label paper production technology, and in particular to a visual inspection device for self-adhesive label paper production. Background Technology

[0002] Visual inspection devices for self-adhesive label production typically consist of a camera, lighting system, control device, and protection device. Industrial cameras are mostly used on production lines to monitor products or operating equipment in real time. Since the camera lens is exposed during monitoring, and the quality of the detected image is related to the lens's sharpness, when industrial cameras are used in non-cleanroom or factory environments, dust generated in the workshop or factory can easily adhere to the camera surface through airborne transmission, even adhering to the front lens, which can affect the inspection effect and lead to false detections. Furthermore, even when the existing industrial camera lens is not in operation, it is still exposed to dust. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a visual inspection device for the production of self-adhesive label paper, which solves the problems of dust easily adhering to the lens surface and the inability to store the lens when it is not in use.

[0004] This invention provides a visual inspection device for the production of self-adhesive label paper, employing the following technical solution: A visual inspection device for producing self-adhesive label paper includes an inspection platform of the main body, with winding and unwinding components for winding and unwinding self-adhesive label paper fixedly connected to both sides of the inspection platform, and an inspection structure for visual inspection of self-adhesive label paper fixedly connected to the inspection platform. The detection structure includes a rotating storage component that drives and adjusts the cleaning and dust blowing component, and an opening and closing dustproof component is provided inside the rotating storage component at the bottom. The rotating storage assembly includes a mounting bracket fixed to the testing table. A rotating connection groove is provided below the mounting bracket, and a storage groove is provided on one side of the rotating connection groove for sliding and storing the dustproof assembly components. The rotating connecting groove has three through connecting grooves on the upper part inside, and a mounting hole for fixing the electric telescopic rod is provided on one side inside the rotating connecting groove.

[0005] Through the above technical solution, by using the three through-cut connecting slots, it is convenient to fix one end of the first traction rope and the second traction rope to the rack frame. The rack frame can drive the first traction rope and the second traction rope to move synchronously under the force extension and contraction adjustment. The synchronous movement of the first traction rope and the second traction rope can achieve sliding opening and closing and sliding lifting of the dustproof plate and the fixed connecting plate.

[0006] Optionally, a sliding storage groove is provided on one side of the aforementioned rotating connecting groove, which is connected to the mounting hole, and the sliding storage groove can accommodate a rack frame that is fixedly connected to the output end of the electric telescopic rod.

[0007] The above technical solution utilizes a sliding storage slot to conveniently store the adjustable dustproof plate. This not only prevents the industrial vision camera from interfering with its normal operation, but also allows the dustproof plate to gradually extend and shield against dust during the camera's rotation and storage process. Furthermore, the adjustable dustproof plate can be made of plastic, which reduces its overall weight and allows for easy adjustment under load.

[0008] Optionally, the rack frame is meshed with the sector gear, and the sector gear is fixedly connected to the convex bearing frame. An industrial vision camera capable of visually inspecting self-adhesive labels is fixedly connected below the convex bearing frame, and the convex bearing frame is rotatably disposed below the rotating connecting groove.

[0009] Through the above technical solution, the sector gears are designed as semi-circular gears, which can rotate and extend the industrial vision camera. There are two sector gears, and the corresponding rack frame also has two racks, which improves the stability of the rotation adjustment of the industrial vision camera.

[0010] Optionally, the above-mentioned cleaning and dust blowing assembly includes a fixed connecting plate with a guide sliding groove, and two guide sliding blocks are symmetrically slidable inside the guide sliding groove. A cavity plate and a driving connecting block are fixedly connected between the two guide sliding blocks, and air blowing holes are opened in a ring array on the surface of the cavity plate. An air blowing guide plate that can deliver airflow upward is fixedly connected inside the air blowing holes.

[0011] Through the above technical solution, by setting up air blowing guide plates, and having multiple air blowing guide plates, each air blowing guide plate is set in a curved circular plate structure, so that the airflow can be conveniently transported upward along the air blowing guide plates. When the airflow is transported upward, it can blow away the dust particles adhering to the surface of the industrial vision camera lens. By blowing the dust upward on the industrial vision camera lens, it can also conveniently blow away the dust adhering to the surface of the soft brush.

[0012] Optionally, a soft brush for cleaning industrial vision camera lenses is fixedly connected to the surface of the cavity plate, and a conveying hole is provided through the bottom of the cavity plate to facilitate the delivery of airflow into the cavity plate.

[0013] Through the above technical solution, the soft brush can effectively clean dust particles adhering to the surface of the industrial vision camera lens during its up-and-down movement. Furthermore, the vibration force received during the lifting and lowering process can rotate and shake off the dust adhering to the surface, preventing dust from adhering to the soft brush surface and causing incomplete cleaning.

[0014] Optionally, the cavity plate has an installation connection hole on one side, and the installation connection hole is fixedly connected to one end of the first spring. The other end of the first spring is fixedly connected to one end of the sliding rod, and the other end of the sliding rod is fixedly connected to one side of the trapezoidal extrusion block. An extrusion adjustment rod is fixedly connected above the surface of the trapezoidal extrusion block, and the extrusion adjustment rod is in sliding extrusion contact with the trapezoidal block. The trapezoidal block is fixedly connected to the surface of the fixed connection plate by a fixing nut.

[0015] Through the above technical solution, the trapezoidal block can be squeezed and stored under the pressure of the compression adjustment rod, allowing the overall fixed connecting plate to slide without force. The trapezoidal block has a through groove on one side, which facilitates the sliding of the rod and avoids interference with the rod's movement caused by the trapezoidal block.

[0016] Optionally, the top of the cavity plate is fixedly connected to one end of the second spring, and the other end of the second spring is fixedly connected to the bottom of the limiting plate. The limiting plate is fixedly connected to the top of the fixed connecting plate. A third spring is fixedly connected to the bottom of the fixed connecting plate, and a through-hole sliding plate that can slide and adjust below the fixed connecting plate is fixedly connected to the top of the third spring. A compressed air pump is fixedly connected between the through-hole sliding plate and the fixed connecting plate, and air outlet pipes that penetrate the through-hole sliding plate are embedded on both sides below the compressed air pump. The air outlet pipes slide and connect with the conveying hole.

[0017] Through the above technical solution, the set compression air pump can not only buffer the fixed connecting plate during its descent, but also use the impact force of the fixed connecting plate during its descent to compress the compression air pump, delivering the air inside the compression air pump into the fixed connecting plate and blowing it onto the surface of the industrial vision camera lens for cleaning. The compression air pump is made of plastic and adopts the push-type air pump design found in existing technology, which allows for convenient air intake and expulsion processes through its own compression and elastic recovery.

[0018] Optionally, two extrusion columns are fixedly and symmetrically connected to the bottom of the cavity plate, and the two extrusion columns simultaneously exert force on the air pump. A driving rod that can synchronously drive and adjust the trapezoidal extrusion block is fixedly connected to one side of the driving connecting block, and a first traction rope is fixedly connected above the driving connecting block. One end of the first traction rope passes through the connecting groove and is fixedly connected to one side of the rack frame.

[0019] Through the above technical solution, the first traction rope can be used to adjust the sliding motion of the connecting block under force. Under the force applied to the connecting block, the fixed connecting plate can also be adjusted under force. Furthermore, the first traction rope is made of thin steel wire rope, which not only avoids wear and breakage of the first traction rope, but also effectively extends the service life of the first traction rope.

[0020] Optionally, the dustproof opening and closing assembly includes an adjustable dustproof plate with a fourth spring fixedly connected to one side, and one end of the fourth spring is fixedly connected to the inside of the storage groove. The adjustable dustproof plate slides and pulls inside the storage groove for adjustment, and a second traction rope is fixedly connected to the other side of the adjustable dustproof plate. The other end of the second traction rope passes through the connecting groove and is fixedly connected to both sides of the rack frame symmetrically.

[0021] Through the above technical solution, two second traction ropes are set and fixed on the symmetrical sides of the adjusting dustproof plate. By setting them on the symmetrical sides of the adjusting dustproof plate, motion interference with the industrial vision camera can be avoided and the normal detection work of the industrial vision camera can be affected. At the same time, the second traction ropes are also made of thin steel wire ropes.

[0022] In summary, the present invention has at least one of the following beneficial effects: When the industrial vision camera is not in use, the electric telescopic rod drives the rack frame to move. During the force-driven movement of the rack frame, the sector gear is driven to rotate. During the force-driven movement of the sector gear, the industrial vision camera will be gradually rotated and stored inside the rotating connecting slot. After the industrial vision camera is completely rotated and stored inside the rotating connecting slot, the dustproof plate can be adjusted to cover the rotating connecting slot, thus protecting the stored industrial vision camera from dust.

[0023] After the industrial vision camera is rotated and stored, the cavity plate slides downwards under force. During this downward movement, the soft brush moves downwards simultaneously, providing initial cleaning of the camera lens. Simultaneously, the cavity plate, under pressure from the through-hole sliding plate, compresses the air pump, sending air from inside the pump into the cavity plate and out through the air vents, effectively cleaning the camera lens. Furthermore, the cavity plate, through the intermittent reciprocating elastic adjustment of the third spring, carries the soft brush to repeatedly wipe and clean the camera lens. Dust adhering to the brush surface is shaken off by the vibration, preventing excessive dust buildup at the brush tip from affecting the cleaning effect.

[0024] As the industrial vision camera rotates under increasing force, the second traction rope gradually carries the dustproof plate as it slides, which can shield the fully retracted industrial vision camera from dust. This prevents the industrial vision camera from having an opening below the rotating connection slot after being retracted, which would otherwise cause dust or particles to adhere to the lens of the industrial vision camera.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figures 1-9 The present invention will be described in further detail below.

[0028] Please refer to the attached diagram in the instruction manual. Figure 1 An embodiment of the present invention provides a visual inspection device for the production of self-adhesive label paper, comprising an inspection table 1 of the main body, on both sides of the inspection table 1 being fixedly connected to a winding and unwinding component 2 for winding and unwinding self-adhesive label paper, and an inspection structure 3 for visual inspection of self-adhesive label paper being fixedly connected to the inspection table 1.

[0029] The testing station 1 and the take-up and unwinding assembly 2 both adopt existing technical structures. The take-up and unwinding assembly 2 can be used to rotate and unwind the self-adhesive label paper and rotate and rewind the self-adhesive label paper after testing.

[0030] See the attached diagram in the instruction manual. Figure 2 , Figure 3 , Figure 4 and Figure 5 The detection structure 3 includes a rotating storage component 301 that drives and adjusts the cleaning and dust blowing component 302, and an opening and closing dustproof component 303 is provided inside the lower part of the rotating storage component 301. The rotating storage assembly 301 includes a mounting bracket 3011 fixed on the testing table 1. A rotating connecting groove 3012 is provided below the mounting bracket 3011, and a storage groove 3013 is provided on one side of the rotating connecting groove 3012 for sliding storage of the components of the opening and closing dustproof assembly 303. The rotating connecting groove 3012 has three through connecting grooves 3014 on the upper part of its interior, and a mounting hole 3015 is provided on one side of the rotating connecting groove 3012 for fixing the electric telescopic rod 3016.

[0031] The storage slot 3013 and the rotating connection slot 3012 are both rectangular and matched. This not only facilitates the adjustment of the dustproof plate 3031 to prevent dust, but also allows the dustproof plate 3031 to be completely stored inside the storage slot 3013, thus avoiding interference with the rotation of the industrial vision camera 30111.

[0032] See the attached diagram in the instruction manual. Figure 2 , Figure 3 , Figure 4 and Figure 5 The rotating connecting groove 3012 has a sliding storage groove 3017 on one side that is connected to the mounting hole 3015. The sliding storage groove 3017 can store the rack frame 3018 that is fixedly connected to the output end of the electric telescopic rod 3016.

[0033] The rack and pinion frame 3018 can be gradually stored inside the sliding storage slot 3017. By gradually storing the rack and pinion frame 3018 inside the sliding storage slot 3017, motion interference caused by the rotating storage and rotation extension of the industrial vision camera 30111 can be avoided, which would prevent the industrial vision camera 30111 from being rotated, stored and extended smoothly.

[0034] See the attached diagram in the instruction manual. Figure 2 , Figure 3 , Figure 4 and Figure 5 The rack and pinion 3018 is meshed with the sector gear 3019, and the sector gear 3019 is fixedly connected to the convex bearing bracket 30110. An industrial vision camera 30111 capable of visually inspecting self-adhesive labels is fixedly connected below the convex bearing bracket 30110, and the convex bearing bracket 30110 is rotatably disposed inside the lower part of the rotating connecting groove 3012.

[0035] The industrial vision camera 30111 uses existing technology, and the existing industrial vision camera 30111 model is CV60. See the attached diagram in the instruction manual. Figure 6 , Figure 7 and Figure 8The cleaning and dust blowing assembly 302 includes a fixed connecting plate 3021 with a guide sliding groove 3022, and two guide sliding blocks 3023 are symmetrically slidable inside the guide sliding groove 3022. A cavity plate 3024 and a driving connecting block 3025 are fixedly connected between the two guide sliding blocks 3023 respectively. An air blowing hole 3026 is opened through the annular array on the surface of the cavity plate 3024, and an air blowing guide plate 3027 that can deliver airflow upward is fixedly connected inside the air blowing hole 3026.

[0036] The air blowing holes 3026 are provided in multiple ways. The multiple air blowing holes 3026 arranged in a ring can be used to blow air to remove dust from the lens of the industrial vision camera 30111 and can also remove dust adhering to the end of the soft brush 3028.

[0037] See the attached diagram in the instruction manual. Figure 6 , Figure 7 and Figure 8 A soft brush 3028 for cleaning the lens of an industrial vision camera 30111 is fixedly connected to the surface of the cavity plate 3024, and a conveying hole 3029 is provided at the bottom of the cavity plate 3024 to facilitate the delivery of airflow into the cavity plate 3024.

[0038] See the attached diagram in the instruction manual. Figure 6 , Figure 7 and Figure 8 A mounting connection hole 30210 is provided on one side of the cavity plate 3024, and one end of the first spring 30211 is fixedly connected inside the mounting connection hole 30210. The other end of the first spring 30211 is fixedly connected to one end of the sliding rod 30212, and the other end of the sliding rod 30212 is fixedly connected to one side of the trapezoidal extrusion block 30213. An extrusion adjustment rod 30214 is fixedly connected above the surface of the trapezoidal extrusion block 30213, and the extrusion adjustment rod 30214 slides and extrudes into contact with the trapezoidal block 30215. The trapezoidal block 30215 is fixedly connected to the surface of the fixed connection plate 3021 by a fixing nut.

[0039] The cavity plate 3024 is rectangular, and its falling speed is greater than the sliding closing speed of the adjustable dustproof plate 3031. This allows the dust or particulate matter cleaned by the soft brush 3028 or by air blowing on the surface of the cavity plate 3024 to be easily discharged through the outlet of the rotating connecting groove 3012 and the outlet of the adjustable dustproof plate 3031. This avoids the dust or particulate matter after cleaning from adhering to the surface of the industrial vision camera 30111 in the closed state.

[0040] See the attached diagram in the instruction manual. Figure 6 , Figure 7and Figure 8 The top of the cavity plate 3024 is fixedly connected to one end of the second spring 30216, and the other end of the second spring 30216 is fixedly connected to the bottom of the limiting plate 30217. The limiting plate 30217 is fixedly connected to the top of the fixed connecting plate 3021. A third spring 30218 is fixedly connected to the bottom of the fixed connecting plate 3021, and a through-hole sliding plate 30219 that can slide and adjust below the fixed connecting plate 3021 is fixedly connected to the top of the third spring 30218. A compression air pump 30220 is fixedly connected between the through-hole sliding plate 30219 and the fixed connecting plate 3021. An air outlet pipe 30221 that penetrates the through-hole sliding plate 30219 is embedded on both sides below the compression air pump 30220. The air outlet pipe 30221 slides and connects with the conveying hole 3029.

[0041] The third spring 30218 is provided with four springs. By utilizing the elastic recovery of the multiple third springs 30218, the cavity plate 3024 can be driven to perform a brief reciprocating sliding adjustment. The cavity plate 3024 can perform a reciprocating cleaning of the lens of the industrial vision camera 30111 through the brief reciprocating sliding adjustment. This reciprocating cleaning not only makes the lens of the industrial vision camera 30111 cleaner more thoroughly, but also avoids incomplete cleaning after a single cleaning.

[0042] See the attached diagram in the instruction manual. Figure 6 , Figure 7 and Figure 8 Two extrusion columns 30222 are fixedly and symmetrically connected to the bottom of the cavity plate 3024. The two extrusion columns 30222 simultaneously compress the air pump 30220. A driving rod 30223 is fixedly connected to one side of the connecting block 3025, which can simultaneously drive and adjust the trapezoidal extrusion block 30213. A first traction rope 30224 is fixedly connected above the connecting block 3025. One end of the first traction rope 30224 passes through the connecting groove 3014 and is fixedly connected to one side of the rack frame 3018.

[0043] The cavity plate 3024 is installed at one-third of the lower position of the fixed connecting plate 3021. This allows the cavity plate 3024 to slide down a distance less than the sliding and sealing distance of the dustproof plate 3031. This facilitates the cavity plate 3024 sliding down during the rotation, storage, and sliding of the dustproof plate 3031 and the industrial vision camera 30111. At this time, the cavity plate 3024 has already slid down, allowing for reciprocating cleaning of the lens of the industrial vision camera 30111 during the rotation and storage process. The relative distance between the lens of the industrial vision camera 30111 and the soft brush 3028 on the surface of the cavity plate 3024 does not exceed 1cm. This preserves the rotation angle space between the soft brush 3028 and the industrial vision camera 30111, and also avoids rotational interference caused by the industrial vision camera 30111 coming into contact with the cavity plate 3024 during rotation.

[0044] See the attached diagram in the instruction manual. Figure 9 The dustproof opening and closing assembly 303 includes an adjustable dustproof plate 3031 with a fourth spring 3032 fixedly connected to one side, and one end of the fourth spring 3032 is fixedly connected to the inside of the storage groove 3013. The adjustable dustproof plate 3031 slides and pulls inside the storage groove 3013 for adjustment, and a second traction rope 3033 is fixedly connected to the other side of the adjustable dustproof plate 3031. The other end of the second traction rope 3033 passes through the connecting groove 3014 and is fixedly connected to both sides of the rack frame 3018 symmetrically.

[0045] Working principle: When using this visual inspection device for self-adhesive label production, when the self-adhesive label needs to be inspected, the electric telescopic rod 3016 is controlled to operate. When the electric telescopic rod 3016 is under force, it carries the rack frame 3018, which drives the sector gear 3019 to rotate. During the rotation of the sector gear 3019, the industrial vision camera 30111 is driven to rotate gradually. Simultaneously, during the gradual movement of the rack frame 3018, the first traction rope 30224 and the second traction rope 3033 are driven to move. During the force-driven movement of 30224, the connecting block 3025 and the driving rod 30223 are driven to slide down along the fixed connecting plate 3021. During the downward movement of the driving rod 30223, it squeezes the trapezoidal squeezing block 30213. At this time, the trapezoidal squeezing block 30213 is squeezed by the force to squeeze the first spring 30211, causing the sliding rod 30212 to slide into the mounting connecting hole 30210. When the driving rod 30223 and the trapezoidal squeezing block 30213 are separated by force, the connecting block 3025 slides down to the bottom of the fixed connecting plate 3021. During the movement of the second traction rope 3033 under force, the fourth spring 3032 elastically recovers, causing the adjusting dustproof plate 3031 to gradually slide into the storage groove 3013 for storage. When the adjusting dustproof plate 3031 gradually slides into the storage groove 3013, the industrial vision camera 30111 gradually rotates out of the rotating connection groove 3012. During the gradual rotation of the industrial vision camera 30111, it also rotates and contacts the soft brush 3028 for rotational cleaning. During the operation of the industrial vision camera 30111, it can perform visual inspection on the continuously conveyed self-adhesive label paper. After all the self-adhesive labels have been inspected, the electric telescopic rod 3016 drives the industrial vision camera 30111 to rotate and retract. During this rotation, the first traction rope 30224 and the second traction rope 3033 are simultaneously subjected to force. The first traction rope 30224, in turn, drives the connecting block 3025 and the driving rod 30223 to move. When the driving rod 30223 contacts the trapezoidal extrusion block 30213, it simultaneously drives the cavity plate 3024 and the soft brush 3028 upwards. When the extrusion adjustment rod 30214 contacts the trapezoidal block 30215, the sliding rod 30212 is gradually extruded. At this point, the trapezoidal extrusion block 30212... After being squeezed and stored, 0213 separates from the trapezoidal block 30215 under force. At this time, the cavity plate 3024 moves downward under its own weight. During the downward movement of the cavity plate 3024, the soft brush 3028 moves synchronously under force. When the cavity plate 3024 carrying the squeezing column 30222 comes into contact with the through hole sliding plate 30219 under force, the through hole sliding plate 30219 squeezes the third spring 30218 and the compression air pump 30220 simultaneously. At this time, the air inside the compression air pump 30220 is transported to the cavity plate 3024 through the air outlet pipe 30221 and the conveying hole 3029, and blown to the surface of the lens of the industrial vision camera 30111 for dust removal through the air blowing hole 3026 and the air blowing guide plate 3027. Furthermore, during the impact process, the third spring 30218 and the second spring 30216 reciprocate and recover elastically, simultaneously carrying the cavity plate 3024 in a reciprocating sliding motion to clean the lens of the industrial vision camera 30111 during the rotation and storage process. The blown airflow carries dust or powder upwards and contacts the top of the rotating connecting groove 3012. At this time, the airflow forms a turning airflow, carrying dust or powder through the opening between the adjusting dustproof plate 3031 and the rotating connecting groove 3012 and is discharged into the rotating connecting groove 3012. When the industrial vision camera 30111 is completely rotated and stored, the adjusting dustproof plate 3031 slides and closes the rotating connecting groove 3012.

[0046] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
