Description

Technical Field

[0001] This utility model relates to the field of protection technology for vision systems of industrial automation equipment, and specifically to a high-protection industrial camera protection device. Background Technology

[0002] In automated equipment operating environments in industrial fields such as cutting, welding, and logistics, vision systems need to capture information such as object features, weld characteristics, and environmental factors in real time using industrial cameras. These industrial cameras must possess reliable protective technology to ensure reliable operation in harsh working environments. Taking welding operations as an example, the welding process involves high temperatures, weld spatter, and metal dust, which can easily lead to camera lens contamination or damage. Even if the industrial camera itself has extremely high protection, it still cannot guarantee the reliable operation of the vision system.

[0003] Existing industrial camera protection solutions mainly include the following:

[0004] The first type: fixed transparent filter: the lens is covered with a transparent material (such as tempered glass), but it is very easy for welding slag to stick to the lens, causing the imaging surface to be contaminated and affecting the imaging quality, and it needs to be replaced frequently.

[0005] The second type is static protection devices, which protect the camera with fixed sealing covers, but cannot balance the needs of protection and real-time monitoring. They require frequent manual opening and closing, which affects work efficiency.

[0006] The third type: Linkage transmission device: It uses multi-stage linkages to achieve baffle rotation, but the structure is complex and the size is large, making it difficult to adapt to the compact installation requirements of the robotic arm end and posing a risk of jamming. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a high-protection industrial camera protection device. It uses a pneumatic mechanism in conjunction with a linear-to-rotary motion mechanism to drive the protective unit to swing. The protective unit can be flipped without a complex linkage structure. The protective unit automatically covers the imaging surface of the industrial camera without the need for manual opening and closing, thus ensuring work efficiency.

[0008] To address the aforementioned technical problems, this utility model provides a high-protection industrial camera protection device, comprising a drive unit and a protection unit. The protection unit covers the imaging surface of the industrial camera in the protection state. The drive unit includes a drive housing, within which a pneumatic mechanism and a linear-to-rotary motion mechanism are disposed. The linear-to-rotary motion mechanism includes a linear motion component and a rotary motion component. The pneumatic mechanism drives the linear motion component to move linearly, and the linear motion component drives the rotary motion component to rotate. The rotary motion component and the protection unit are rigidly connected via a connector. The rotary motion component, through the connector, causes the protection unit to swing, thereby opening and closing the imaging surface of the industrial camera.

[0009] Furthermore, the pneumatic mechanism includes a piston cylinder, a piston rod, and an air source. The side of the drive housing is provided with an air inlet and an air outlet that communicate with the piston cylinder at intervals along the axis of the piston cylinder. The piston rod is sealed and slidably disposed inside the piston cylinder. The air inlet and the air outlet are respectively connected to the air source through an air inlet passage and an air outlet passage. Solenoid valves are provided on both the air inlet passage and the air outlet passage.

[0010] Furthermore, two sets of piston cylinders are arranged radially at intervals, and the inlet and outlet ends of the two piston cylinders are connected by air passages.

[0011] Furthermore, the linear component includes a drive nut, the rotating component includes a drive screw, the axis of the drive screw is parallel to the axis of the piston cylinder, the drive nut is threadedly engaged with the drive screw, the drive nut is fixedly connected to the piston rod through a connecting rod, both ends of the drive screw are rotatably mounted on the drive housing, and the connecting component is fixedly connected to the end of the drive screw.

[0012] Furthermore, the two ends of the drive screw are provided with smooth small diameter sections, which are rotatably mounted on the drive housing via bearings.

[0013] Furthermore, the protective unit includes a protective baffle, the size of which is adapted to the size of the imaging surface of the industrial camera, and the inner side of the protective baffle is provided with a heat insulation component and a buffer component.

[0014] Furthermore, both the heat insulation element and the buffer element are annular, and the heat insulation element is disposed within the outline of the buffer element.

[0015] Furthermore, the protection unit also includes a status sensor disposed on the protection baffle, the status sensor being used to monitor the opening and closing status of the protection unit.

[0016] Furthermore, the status sensor is a photosensitive sensor installed inside the heat insulation component.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) The drive unit uses pneumatics to achieve rapid response. The pneumatic mechanism can use compressed air, which is common in automated production lines, as the power source, making it easy to integrate into the production line. The pneumatic mechanism is used in conjunction with a linear-to-rotary motion mechanism. The linear motion component drives the rotary motion component to rotate, which in turn drives the protective unit to swing. The overall structure is simple and compact. The protective unit can be flipped without a complex linkage structure, reducing the risk of jamming. The drive mechanism provides a reliable and stable driving force for the movement of the protective unit. When protection is needed, the protective unit automatically covers the imaging surface of the industrial camera to prevent the camera lens from being contaminated or damaged. When the industrial camera needs to work, the protective unit moves away from the imaging surface of the industrial camera. The whole operation is automated and does not require manual opening and closing, ensuring work efficiency. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings: Specific Implementation Example 1:

[0029] In this embodiment, as Figure 1 , 2 As shown, the length direction of the industrial camera 3 is the left-right direction, the width direction of the industrial camera 3 is the front-back direction, and the surface where the imaging surface 31 of the industrial camera is located is the front.

[0030] refer to Figures 1 to 5 This utility model discloses a high-protection industrial camera 3 protection device (hereinafter referred to as the protection device), which includes a drive unit 1 and a protection unit 2.

[0031] The drive unit 1 is fixedly mounted on the upper surface of the industrial camera 3. It uses compressed air (0.2 to 0.6 MPa), commonly found in automated production lines, as its power source to provide a reliable and stable driving force for the protective device. This enables the protective unit 2 to rotate and open / close along the edge of the industrial camera's imaging surface 31. The protective unit 2 covers the industrial camera's imaging surface 31 in the protective state, providing all-around protection and displaying the open or closed status of the protective device.

[0032] Specifically, the drive unit 1 includes a drive housing 11, and the left and right sides of the drive housing 11 are fixedly mounted on the upper end of the industrial camera 3 via transition sheet metal 115. The drive housing 11 contains a pneumatic mechanism 12 and a linear-to-rotary motion mechanism, wherein the linear-to-rotary motion mechanism includes a linear motion component and a rotary motion component. The pneumatic mechanism 12 drives the linear motion component to move linearly, and the linear motion component drives the rotary motion component to rotate. The rotary motion component's protective unit 2 is rigidly connected via a connector 14. The rotary motion component, through the connector 14, drives the protective unit 2 to swing, thereby opening and closing the industrial camera's imaging surface 31.

[0033] Drive unit 1 utilizes pneumatics for rapid response, with an opening and closing time of ≤0.5s, meeting the real-time protection requirements of welding / cutting scenarios and the fast cycle time of automated production lines. Pneumatic mechanism 12 uses compressed air, commonly found in automated production lines, as its power source, facilitating integration into the production line. Pneumatic mechanism 12, in conjunction with a linear-to-rotary motion mechanism, drives a rotary motion component through linear motion, thereby causing the protective unit 2 to swing. The overall structure is simple and compact, eliminating the need for complex linkage structures to achieve the rotation of the protective unit 2, reducing the risk of jamming.

[0034] The drive mechanism provides a reliable and stable driving force for the movement of the protective unit 2. When protection is required, the protective unit 2 automatically covers the imaging surface 31 of the industrial camera to prevent the camera lens 32 from being contaminated or damaged. When the industrial camera 3 needs to work, the protective unit 2 moves away from the imaging surface 31 of the industrial camera. The whole operation is automated and does not require manual opening and closing, ensuring work efficiency.

[0035] Preferably, in this embodiment, the pneumatic mechanism 12 includes a piston cylinder 15, a piston rod 16, and an air source (not shown in the figure). In this embodiment, the pneumatic mechanism 12 is integrally disposed on the rear side of the inner cavity of the drive housing 11, and the axis of the piston cylinder 15 extends in the left-right direction. The rear side of the drive housing 11 is provided with an air inlet 18 and an air outlet 19 communicating with the piston cylinder 15 at intervals along the axis of the piston cylinder 15. The piston rod 16 is slidably disposed within the piston cylinder 15 and is sealed with a sealing medium to form a piston mechanism. In this embodiment, the sealing medium includes, but is not limited to, sealing rings, Glyd rings, C-rings, etc. How to achieve the sliding sealing fit between the piston rod 16 and the piston cylinder 15 is common knowledge well known to those skilled in the art and will not be elaborated here.

[0036] In this embodiment, the air inlet 18 and air outlet 19 are connected to the air source through the air inlet passage 118 and air outlet passage 119, respectively. Solenoid valves 117 are installed on both the air inlet passage 118 and air outlet passage 119. The piston rod 16 moves linearly under the action of compressed air. The solenoid valves 117 are linked with the automated equipment control system. If a visual system is detected to require shooting or shutting down, the solenoid valves 117 on the air inlet passage 118 and air outlet passage 119 are immediately activated to switch the air paths, thereby causing the piston mechanism to reciprocate.

[0037] Specifically, in this embodiment, such as Figure 4 , 5 As shown, a piston block 17 is provided inside the drive housing 11, and a piston cylinder 15 is integrated inside the piston block 17. A sealing block 121 is provided on the side of the piston cylinder 15 facing away from the piston cylinder 15, and the sealing block 121 cooperates with the piston rod 16 to form a sealing structure. In this embodiment, an elastic buffer mechanism is also provided at the extreme position of the reciprocating linear trajectory of the pneumatic mechanism 12 piston mechanism to reduce mechanical vibration caused by rigid impact. Specifically, the elastic buffer mechanism is an elastic block provided on the side of the sealing block 121 facing the piston rod 16. The elastic block can be a rubber or nylon elastic block. Of course, in other embodiments, the elastic buffer mechanism can also be an elastic plate or a buffer spring.

[0038] In this embodiment, preferably, two sets of piston mechanisms are spaced apart along the front-to-back direction. Specifically, two sets of piston cylinders 15 are spaced apart along the front-to-back direction inside the piston block 17. The air inlet and outlet ends of the two piston cylinders 15 are connected through air passages 110 opened inside the piston block 17. Each piston cylinder 15 is provided with a matching piston rod 16, realizing the parallel design of the two sets of piston mechanisms. The synchronous operation of the two sets of piston mechanisms is achieved by using a set of air inlet holes 18 and air outlet holes 19. The redundant design of the two sets of piston mechanisms ensures stable movement on the one hand, and on the other hand, when any piston mechanism fails, the pneumatic mechanism 12 can still maintain its function, improving reliability. Of course, in other embodiments, the number of piston mechanisms can be set according to actual usage requirements, such as three or four sets spaced apart.

[0039] Preferably, in this embodiment, the linear-to-rotary motion mechanism is located at the front of the drive housing 11, ensuring a compact internal structure and reducing the overall volume of the protective device, thus making it miniaturized and lightweight. Specifically, the linear component includes a drive nut 111, the rotary component includes a drive screw 112, and the linear-to-rotary motion mechanism is a screw-nut mechanism 13 composed of the two. To ensure that the drive nut 111 smoothly drives the drive screw 112 to rotate, in this embodiment, the screw-nut mechanism 13 can be a ball screw-nut mechanism 13.

[0040] The axis of the drive screw 112 is parallel to the axis of the piston cylinder 15. The drive nut 111 is threaded into the drive screw 112. The drive nut 111 is fixedly connected to the piston rod 16 via a connecting rod 120 extending in the front-rear direction. Both ends of the drive screw 112 are rotatably mounted on the drive housing 11. The connecting piece 14 is fixedly connected to the end of the drive screw 112. Specifically, in this embodiment, the connecting rod 120 is rigidly fixedly connected to the ends of the two piston rods 16 and the end of the drive nut 111 by screws, ensuring that the piston rods 16 move synchronously and the thrust is uniform.

[0041] The piston rod 16 is affected by the compressed air introduced from the air inlet 18 or the air outlet 19, and moves to the left or right in a straight line. Then, through the connecting rod 120, it drives the drive nut 111 to move in a straight line in the left and right direction, thereby driving the drive screw 112 to rotate clockwise or counterclockwise in an arc along its axis.

[0042] In this embodiment, specifically, both ends of the drive screw 112 are provided with smooth small-diameter sections 113. Mounting through holes adapted to the smooth small-diameter sections 113 are provided on the left and right sides of the drive housing 11. The smooth small-diameter sections 113 are rotatably mounted in the mounting through holes of the drive housing 111 via bearings 114. The smooth small-diameter sections 113 of the drive screw 112 and their threaded sections form shoulders, suppressing axial and radial movement of the drive screw 112. Simultaneously, bearing baffles 122, fixed to the drive housing 111, are provided on the outside of the mounting through holes via screws, thus fixing the bearing 114 mechanism.

[0043] In this embodiment, the connector 14 is as follows: Figure 1 , 2 The L-shaped connecting arm shown is provided on both the left and right sides of the drive screw 112. The side of the L-shaped connecting arm facing the drive screw 112 is rigidly fixed to the end of the drive screw 112 by screws, and the other side is fixedly connected to the protective unit 2. Under the drive of the drive screw 112, the protective unit 2 rotates clockwise or counterclockwise along the axis of the drive cylinder to complete the closing and opening actions. At the same time, it ensures that the protective unit 2 does not interfere with the drive housing 11 when it is open, and that the protective unit 2 can be tightly attached to the imaging surface 31 of the industrial camera when it is closed.

[0044] In this embodiment, the protective unit 2 includes a protective baffle 21. The size of the protective baffle 21 is adapted to the size of the imaging surface 31 of the industrial camera. The exposed surface of the protective baffle 21 is treated with a high-temperature resistant surface treatment process to prevent high-temperature splashes from metallurgically bonding with the protective baffle 21. The high-temperature resistant surface treatment process includes, but is not limited to, micro-arc oxidation and PEFE coating.

[0045] The inner side of the protective baffle 21 is provided with a heat insulation component 22 and a buffer component 23. The buffer component 23 is used to contact the imaging surface 31 of the industrial camera. In this embodiment, the buffer component 23 is a buffer rubber. The buffer component 23 absorbs the buffer energy during the closing process of the protective device and undergoes compression deformation, thereby forming a full-circumferential seal protection with the imaging surface 31 of the industrial camera in the closed state. The heat insulation component 22 is heat insulation cotton with a hardness lower than that of the buffer component 23, which reduces the adverse effects of the external high temperature environment on the thermal devices and other parts of the industrial camera 3. In the protective state, the heat insulation component 22 transitions with the imaging surface 31 of the industrial camera in the compressed state, further preventing the intrusion of external foreign objects.

[0046] Preferably, in this embodiment, both the heat insulation member 22 and the buffer member 23 are annular, and the heat insulation member 22 is disposed within the outline of the buffer member 23.

[0047] The protective unit 2 also includes a status sensor 24 disposed on the protective baffle 21. The status sensor 24 is used to monitor the opening and closing status of the protective unit 2. Specifically, in this embodiment, the status sensor 24 is a photosensitive sensor disposed inside the heat insulation component 22. In other embodiments, the status sensor 24 may also be a magnetic sensor, a mechanical micro switch, a pressure sensor, etc.

[0048] When the high-protection industrial camera 3 protection device completes its closed operation, the status sensor 24 detects that the gap between the protective baffle 21 and the industrial camera imaging surface 31 has reached the closing threshold. In this state, the sensor 24 then triggers the corresponding sensor on the industrial camera imaging surface 31 to generate a closing signal and issues a closing state command. Similarly, when the high-protection industrial camera 3 protection device performs its opening operation, the status sensor 24 detects that the gap between the protective baffle 21 and the industrial camera imaging surface 31 has reached the opening threshold. In this state, the sensor 24 then triggers the corresponding sensor on the industrial camera imaging surface 31 to generate an opening signal and issues an opening state command.

[0049] In this embodiment, the protective baffle 21 has matching grooves at the positions corresponding to the buffer 23 and the heat insulation 22. The buffer 23 and the heat insulation 22 are fixedly installed in the corresponding grooves using a high-temperature resistant adhesive. A matching blind hole is provided on the protective baffle 21 at the position corresponding to the status sensor 24. The status sensor 24 is fixedly installed in the blind hole using a high-temperature resistant adhesive. The specific type of high-temperature resistant adhesive used is common knowledge well-known to those skilled in the art, and will not be elaborated further.

[0050] The control process for the high-protection industrial camera 3 protection device of this application is as follows:

[0051] Activation Action: When the vision system of the automated equipment receives the shooting command, it switches to the activation action air path, and compressed air is pumped into the drive unit 1 to drive the piston mechanism to move linearly, which in turn drives the linear-to-rotary motion mechanism to rotate, and the protection unit 2 is fully activated.

[0052] Closing action: When the vision system of the automated equipment receives the shooting completion command, the pneumatic solenoid valve 117 reverses, the air pressure reverses and drives the piston mechanism to retract, and the protection unit 2 is fully closed.

[0053] Status feedback: During the closing action, if the device is fully closed, the status monitoring sensor will issue a status command, allowing the automated equipment to proceed to the next work command; conversely, if the accidental protection unit 2 is not fully closed, the system will not allow the automated equipment to proceed to the next work command.

[0054] In summary, the protection device of this invention utilizes a redundant design of a parallel multi-stroke piston mechanism, which can maintain functionality even if any piston mechanism fails, thus improving reliability. High protection is achieved through the use of buffer 23 and heat insulation 22, reaching IP55 protection when closed, and it allows for a non-electrical design, providing reliable protection for the stable operation of the industrial camera 3 under harsh conditions. It achieves rapid pneumatic response, with an opening and closing action time ≤0.5s, meeting the real-time protection requirements of welding or cutting scenarios and the fast-paced requirements of automated production lines.

[0055] Example 2: This example provides a different pneumatic mechanism. Unlike Example 1, in this example, when meeting actual usage requirements, the piston mechanism of the pneumatic mechanism can be an electric cylinder. In this case, two sets of electric cylinders are connected in parallel inside the drive housing. The air inlet and air outlet of the electric cylinder are connected to the air inlet and air outlet on the drive housing, respectively, which facilitates installation and maintenance.

[0056] Example 3: This example provides a different linear-to-rotary motion mechanism. Unlike Example 1, in this example, to meet actual usage requirements, the linear-to-rotary motion mechanism is a gear and rack mechanism, which includes a meshing drive gear and a drive rack. A rotating shaft extending in the left-right direction is provided at the front of the drive housing cavity. Both ends of the rotating shaft are rotatably engaged with the drive housing. A connecting piece is fixedly connected to the end of the rotating shaft. A drive gear is mounted on the rotating shaft to prevent rotation. The drive rack is located at the bottom of the drive housing cavity and extends in the front-back direction.

[0057] Specifically, a groove extending in the front-to-back direction and adapted to the drive rack is provided at the bottom of the inner cavity of the drive housing. The drive rack is slidably disposed in the groove. The axis of the piston cylinder extends in the front-to-back direction, and the end of the piston rod is fixedly connected to the drive rack. The piston rod is driven to reciprocate in the front-to-back direction by a pneumatic source, which in turn drives the drive rack to move, thereby driving the drive gear to rotate and causing the protective unit to flip, thus realizing the opening and closing of the imaging surface of the industrial camera.

[0058] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0059] In the description of the embodiments of this application, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0060] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
