Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, and in particular to a mobile visual inspection system. Background Technology

[0002] In industrial production quality control, visual inspection technology, with its non-contact, high-precision, and high-efficiency characteristics, has become a core technical means for verifying the dimensions of parts and screening for appearance defects.

[0003] To adapt to the multi-station inspection needs of production lines, portable vision inspection equipment has become an important choice in current flexible manufacturing scenarios due to its ability to be flexibly transferred to different workstations. While portable vision inspection equipment can be moved to the target workstation using simple handling tools, thus meeting the flexibility requirements of multi-station inspection to some extent, it faces significant protection challenges during transportation: On the one hand, vision inspection equipment contains precision components such as high-precision lenses and image sensors, which are easily displaced or damaged by accidental bumps during handling, directly affecting inspection accuracy and even causing equipment failure; on the other hand, existing simple handling tools lack dedicated protective structures, and there is no cushioning and shock absorption design after the equipment is placed. When the production line floor is uneven or the transfer speed changes, the equipment is prone to sliding and bumping, further increasing the risk of damage to precision components. Even if some improved handling equipment attempts to add simple fence structures, it can only prevent falls and cannot buffer against external forces such as vibration and impact during transportation, thus failing to solve the problem of protecting precision components.

[0004] In summary, technical personnel are urgently needed to solve the above problems. Utility Model Content The purpose of this invention is to provide a mobile vision inspection system that addresses the problem of fragile precision components and compromised inspection accuracy caused by the lack of dedicated buffer protection during the transport of existing portable vision inspection equipment. It also overcomes the shortcomings of existing improved handling equipment that can only prevent falls but lacks cushioning and shock absorption.

[0005] This utility model relates to a mobile visual inspection system, which is composed of a transport trolley and a visual inspection device; the transport trolley includes a load-bearing chassis, a walking mechanism, and a buffer protective compartment; The walking mechanism is assembled at the bottom of the load-bearing chassis; The buffer protective chamber is used to restrain and protect the visual inspection equipment, and it is supported by a load-bearing chassis; The visual inspection equipment is placed in a buffer protective chamber and relies on the mobility of the transport trolley through the walking mechanism to stop and inspect at different locations on the production line.

[0006] As a further improvement to the technical solution disclosed in this utility model, the buffer protection chamber includes an outer protective frame, an open bakelite carrier, and a foam buffer frame; the outer protective frame serves as an outer support structure; the open bakelite carrier is used to provide stable middle support and isolate electrostatic interference, and it is nested inside the outer protective frame; the foam buffer frame is used to directly absorb vibration energy during transportation, and it is directly attached to the side wall of the visual inspection equipment and nested inside the open bakelite carrier.

[0007] As a further improvement to the technical solution disclosed in this utility model, the walking mechanism consists of two sets of fixed casters and two sets of swivel casters; both the fixed casters and the swivel casters are detachably fixed to the load-bearing chassis; the two sets of fixed casters are fixed to the rear sides of the bottom wall of the load-bearing chassis to help limit the direction of movement; the two sets of swivel casters are fixed to the front sides of the bottom wall of the load-bearing chassis, and can rotate 360° to adjust the steering direction of the transport trolley, and cooperate with the fixed casters to achieve flexible movement.

[0008] As a further improvement to the technical solution disclosed in this utility model, the transport trolley also includes a pushing handle; the lower end of the pushing handle is fixed to one end of the load-bearing chassis by welding, bolt connection or plug-in method.

[0009] As a further improvement to the technical solution disclosed in this utility model, the visual inspection equipment includes a cabinet, a camera assembly, a light source, and a power distribution assembly; the cabinet provides installation support for the power distribution assembly, the camera assembly, and the light source; during the photo-taking process, the power distribution assembly ensures the operation of the camera assembly and the light source through power supply, and the light source assists the camera assembly in acquiring workpiece inspection images.

[0012] As a further improvement of the technical solution disclosed in this utility model, the vision inspection equipment also includes a position locking mechanism; the position locking mechanism is mounted on the bottom of the cabinet; when the vision inspection equipment moves to the designated inspection position on the production line, the position locking mechanism applies a lateral pressing force towards the production line track to clamp and fix the vision inspection equipment to the production line track.

[0013] As a further improvement to the technical solution disclosed in this utility model, the position locking mechanism includes a side push plate, a push rod, a quick-locking device, and a guide assembly; the quick-locking device is fixed to the side wall of the cabinet and allows the push rod to pass freely; the side push plate is vertically positioned at the bottom of the cabinet and is connected to the end of the push rod away from the quick-locking device; the guide assembly is mounted on the side wall of the cabinet and cooperates with the side push plate. Initially, the quick-locking device is normally open. When it is necessary to lock the vision inspection equipment, a pushing force is applied to the push rod to cause it to move axially, which moves the side push plate toward the production line track.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 A perspective view of the mobile vision inspection system disclosed in this utility model is shown, indicating that it is composed of a transport trolley 1 and a vision inspection device 2. The transport trolley 1 is responsible for mobile support, providing a safe transport and stable placement basis for the vision inspection device 2. Relying on the mobility of the transport trolley 1, the vision inspection device 2 performs precise stopping and inspection operations at designated locations, jointly meeting the flexible inspection needs of the production line.

[0026] like Figure 2As shown, the transport trolley 1 serves as the mobile support core of the mobile vision inspection system, mainly composed of a load-bearing chassis 11, a walking mechanism 12, a buffer protective chamber 13, and a pushing handle 14. As the core load-bearing component of the transport trolley 1, the load-bearing chassis 11 plays a crucial role in connection and support. The bottom of the load-bearing chassis 11 uses a detachable structure to install and fix the walking mechanism 12, while the top supports and fixes the buffer protective chamber 13, providing placement space for the vision inspection equipment 2. One end of the load-bearing chassis 11 also has a reserved assembly interface for the pushing handle 14 to be fixed using a plug-in method, providing a convenient force application point for operators to push the transport trolley and meeting the mobile operation needs of different production line installation scenarios. Similarly, Figure 2 As shown, the traveling mechanism 12, serving as the moving actuator of the transport trolley 1, includes two sets of fixed casters 121 and two sets of swivel casters 122. All fixed casters 121 and swivel casters 122 are detachably fixed to the bottom wall of the load-bearing chassis 11. In terms of layout, the two sets of fixed casters 121 are symmetrically distributed on both rear sides of the bottom wall of the load-bearing chassis 11, primarily serving to help limit the movement direction of the transport trolley 1 and prevent deviation during transport. The two sets of swivel casters 122 are correspondingly installed on both front sides of the bottom wall of the load-bearing chassis 11, enabling 360° free rotation to flexibly adjust the steering direction of the transport trolley 1. In practical applications, through the synergistic effect of the fixed casters 121 and swivel casters 122, the transport trolley 1 can easily adapt to the complex movement paths of the production line, ensuring that the vision inspection equipment 2 is accurately transferred to the target inspection position.

[0027] The buffer protective chamber 13, as a key structure protecting the visual inspection equipment 2, adopts a multi-layered nested design to meet the protection requirements of the equipment's precision components (such as high-precision lenses and image sensors). Figure 3 , Figure 4 As shown, the buffer protection chamber 13 is composed of an outer protective frame 131, an open bakelite carrier 132, and a foam buffer frame 133 nested together in sequence. The outer protective frame 131 serves as the outer support structure, made of high-strength material, providing a stable framework for the entire buffer protection chamber 13. The open bakelite carrier 132, nested inside the outer protective frame 131, not only provides stable mid-level support for the vision inspection equipment 2, but its bakelite material also possesses excellent electrostatic isolation properties, effectively preventing static electricity in the production line environment from interfering with the precision components in the vision inspection equipment 2. The foam buffer frame 133, nested inside the open bakelite carrier 132, through its direct contact design with the sidewall of the vision inspection equipment 2, actively absorbs vibration energy generated by uneven ground or changes in transport speed during transportation, effectively reducing the risk of bump damage to the vision inspection equipment 2. As described above, the visual inspection equipment 2, as the core inspection component, is housed within the buffer protective chamber 13. It relies on the mobility of the transport trolley 1 via the walking mechanism 12 to move and inspect at different locations on the production line, following the transport trolley 1. For example... Figures 5-7 As shown, the vision inspection equipment 2 mainly consists of a cabinet 21, a camera assembly 22, a light source 23, and a power distribution assembly 24. The cabinet 21 serves as the mounting platform for the vision inspection equipment 2, providing a well-organized installation space and support for components such as the camera assembly 22, the light source 23, and the power distribution assembly 24. During image-based inspection operations, the power distribution assembly 24 ensures a stable power supply for the continuous operation of the camera assembly 22 and the light source 23. Simultaneously, the light source 23 flexibly adjusts its brightness according to the workpiece inspection requirements, assisting the camera assembly 22 in clearly acquiring workpiece inspection images, thereby effectively improving inspection accuracy.

[0028] To further optimize the performance of the visual inspection equipment, the visual inspection equipment 2 is also equipped with a fan 25 and a concealed handle 26. The fan 25 is mounted on the side wall of the cabinet 21 and is electrically connected to the power distribution component 24. During long-term operation, the fan 25 actively dissipates heat from the inside of the cabinet 21, preventing heat buildup from affecting image quality. The concealed handle 26 is mounted on the top wall of the cabinet 21, using a two-pair design and fitting snugly against the cabinet surface, without affecting the overall appearance of the visual inspection equipment 2. When the relative position of the visual inspection equipment 2 within the buffer protective compartment 13 needs to be adjusted individually or when it needs to be lifted out, the operator can easily grip it using the concealed handle 26, improving operational flexibility.

[0029] Furthermore, by Figure 7 , Figure 8 As shown, the visual inspection device 2 is also equipped with a position locking mechanism 27. The position locking mechanism 27 is mounted on the bottom of the cabinet 21 and is specifically used to fix the visual inspection device 2 after it is moved to the designated inspection position, so as to prevent the device from shifting due to vibration during the inspection process and ensure the accuracy of the inspection results. like Figure 8 As shown, the position locking mechanism 27 mainly consists of a side push plate 271, a push rod 272, a quick-locking device 273, and a guide assembly 274. The quick-locking device 273 is fixed to the side wall of the cabinet 21, with a through hole in the middle for the push rod 272 to pass through freely. The side push plate 271 is vertically positioned at the bottom of the cabinet 21 and is connected to the end of the push rod 272 away from the quick-locking device 273. The guide assembly 274 is mounted on the side wall of the cabinet 21 to ensure the side push plate 271 maintains a stable posture and orientation during movement. There are two sets of guide assemblies 274, symmetrically arranged on both sides of the push rod 272. Each guide assembly 274 is composed of a linear bearing 2741 and a guide rod 2742, working together to ensure that the side push plate 271 always moves smoothly in a preset direction.

[0030] In the initial state, the quick-locking device 273 is normally open, and the push rod 272 can move freely along the axial direction. When the vision inspection device 2 moves to the designated inspection position on the production line with the transport trolley 1, the operator applies an axial force to the push rod 272, causing the side push plate 271 to move towards the production line track. After the side push plate 271 contacts the production line track and forms a stable fit, the quick-locking device 273 is switched to the locked state, which locks the axial movement freedom of the push rod 272, thus clamping and fixing the vision inspection device 2 to the production line track. When it is necessary to move the vision inspection device 2, simply reverse the operation of the quick-locking device 273 to switch back to the normally open state, release the restriction on the push rod 272, and then drag the push rod 272 to reset, which will cause the side push plate 271 to disengage from the production line track. The entire operation process is convenient and efficient, and requires no tools. In practical applications, the mobile visual inspection system disclosed in this utility model achieves the following beneficial technical effects: First, the multi-layered nested design of the buffer protective chamber 13 provides all-round protection for the visual inspection equipment 2. The outer outer protective frame 131 resists external impacts, the middle open bakelite carrier 132 isolates electrostatic interference, and the inner foam buffer frame 133 absorbs vibration energy, effectively avoiding the displacement and damage of precision components during the handling of the visual inspection equipment 2, significantly reducing the risk of equipment failure and extending its service life. Second, through the synergistic effect of the buffer protective chamber 13 and the walking mechanism 12, the transportation risks in complex environments such as uneven production line floors and variable transfer paths are effectively mitigated. The shock absorption capacity of the buffer protective chamber 13 effectively prevents the sliding and bumping of the visual inspection equipment 2, while the flexible movement capability of the walking mechanism 12 ensures that the visual inspection equipment 2 can be quickly transferred to different workstations on the production line, achieving inspection on demand and perfectly adapting to the multi-workstation, multi-batch inspection needs in flexible production scenarios.
