Abstract
Description
Technical Field
[0001] This application relates to the field of power strip appearance inspection technology, and in particular to a multi-station power strip appearance inspection device. Background Technology
[0002] Power strips, as indispensable electrical accessories in daily life, are directly related to user safety as their appearance quality affects not only product aesthetics but also user safety. Traditional appearance inspection relies mainly on manual visual inspection, which suffers from low efficiency, high labor intensity, susceptibility to subjective factors, and a high rate of missed inspections. With the increasing automation and intelligence of manufacturing, manual inspection can no longer meet the requirements of modern production for high efficiency, high precision, and consistency. Therefore, developing automated appearance inspection equipment has become a key step in improving the production quality and efficiency of power strips.
[0003] Currently, automated inspection technology based on machine vision has been widely used in the industrial field. This technology uses industrial cameras to capture product images and utilizes image processing algorithms to analyze and identify defects, achieving non-contact, high-speed, and high-precision inspection.

The automatic identification of these defects places high demands on the imaging stability of the vision system, the robustness of the detection algorithm, and the motion control precision of the equipment.
[0004] Many automated inspection equipment adopts fixed-station or single-station inspection modes, which improves inspection efficiency to some extent, but still has the following limitations: such as inspection efficiency bottlenecks, single-station inspection cannot achieve parallel operation of loading and unloading and inspection processes, and the production cycle is limited by the cycle time of a single process; at the same time, there is a lack of flexibility, traditional equipment is often designed for specific models of power strips, and when changing products, it is necessary to readjust the hardware layout and visual parameters, resulting in long changeover times and difficulty in adapting to the flexible production needs of multiple varieties and small batches. Therefore, a multi-station power strip appearance inspection equipment is proposed to solve the problems mentioned above. Summary of the Invention

[0023] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.
[0024] Example 1, such as Figures 1-4 As shown, a multi-station power strip appearance inspection device includes an inspection device 1 consisting of a storage component 12, an inspection component 13, a linear module 14, a material gripping device 16, and a material discharging component 17 mounted on a frame 11. The frame 11 is also equipped with material trays 15 used in conjunction with the material gripping device 16. Specifically, there are three material trays 15, which are equidistantly distributed. Each of the three material trays 15 is equipped with a lifting structure to adjust its height, avoiding height differences caused by removing or stacking the material trays 15. This ensures that the material gripping device 16 can accurately position the material each time, simplifying operation and realizing automated palletizing. Furthermore, the design of three equidistantly distributed material trays 15 increases the quantity and variety of materials that can be stored in a limited space, improving space utilization. At the same time, the materials on the material trays 15 can be flexibly adjusted according to different production needs, facilitating the replacement of different specifications or types of power strips for inspection, and enhancing the adaptability of the equipment to diversified production.
[0025] The placement component 12 in this embodiment includes a circular platform 121 and multiple support frames 122 disposed above the circular platform 121. A detection platform 123 is rotatably mounted on each of the multiple support frames 122. Each of the multiple support frames 122 is equipped with an induction motor 124 for driving the rotation of the detection platform 123. An air cushion slip ring 125 is installed on the bottom side of the circular platform 121 to drive its rotation. More importantly, this solves the problem of cable entanglement during rotation, ensuring long-term, stable, and trouble-free operation of the equipment. The detection component 13 in this embodiment includes a mounting frame 131. A CCD detection probe 132 is slidably disposed on the mounting frame 131. A guide rail 1 is provided between the mounting frame 131 and the CCD detection probe 132. 33. The guide rail 133 provides a stable guide for the sliding of the CCD inspection probe 132, enabling it to move flexibly on the mounting bracket 131 and be precisely positioned above the connector to be inspected, thereby achieving accurate inspection of the connector's appearance and improving the quality and efficiency of the inspection. Specifically, the CCD inspection probe 132 is located above the inspection table 123; the linear module 14 is installed above the frame 11, and the material gripping device 16 is installed on the linear module 14. There are multiple linear modules 14. The design of multiple linear modules 14 allows the material gripping device 16 to move in different linear directions, increasing the flexibility and coverage of material gripping, and enabling it to reach each workstation more quickly and accurately for material gripping and unloading operations, further improving production efficiency.
[0026] The material handling device 16 in this embodiment includes a frame 161 slidably mounted on a linear module 14. A movable structure 162 cooperating with the linear module 14 is provided on the frame 161. A lifting cylinder 163 is installed outside the frame 161, and a suction nozzle 164 is installed on the output end of the lifting cylinder 163. Furthermore, this embodiment achieves parallel processing of multiple workstations through a circular platform 121 and multiple support frames 122 and a detection platform 123 mounted above it. When a connector at one workstation is being detected by a CCD detection probe 132, other workstations can simultaneously perform loading or unloading operations, greatly shortening the production cycle and improving overall equipment efficiency.
[0027] It should be noted that the frame 161 of the material gripping device 16 is slidably mounted on the linear module 14 and is provided with a moving structure 162 that cooperates with the linear module 14. A lifting cylinder 163 is installed externally, and a suction nozzle 164 is installed on the output end of the lifting cylinder 163. This allows the material gripping device 16 to move horizontally and also to lift vertically through the lifting cylinder 163. The suction nozzle 164 can firmly adsorb the inserts, achieving efficient and stable gripping and placement operations, reducing errors and damage during the gripping process, and improving production quality.
[0028] The feeding assembly 17 in this embodiment includes a fixed frame 171 fixed to the top side of the frame 11. A rotary motor 172 is fixed to the top side of the fixed frame 171. A feeding station 173 is installed on the output end of the rotary motor 172. The feeding station 173 has two feeding areas, so that when material is detected and picked up in one feeding area, material can be fed in the other feeding area, eliminating waiting time and realizing uninterrupted continuous production.
[0029] It should be noted that the testing platform 123 is rotatably mounted on the support frame 122 via a rotating shaft. The rotation angle of the testing platform 123 is ±30°, and the rotating shaft of the testing platform 123 is connected to the connecting assembly 2. The angle adjustment of ±30° can be achieved through the fine-tuning platform. Each platform can be adjusted independently. The detection is performed by CCD to ensure the accuracy of detection for different materials. After the material is detected, it is placed into the rotating platform near the unloading station 173 by the material gripping device 16. Then the steps are repeated, and finally the material is placed in the unloading tray 15 to complete the detection process.
[0030] Furthermore, the support frame 122 is equipped with a stop to limit the rotation of the inspection stage 123, allowing it to rotate within preset values. The surface of the guide rail 133 undergoes special treatment, exhibiting excellent wear and corrosion resistance, maintaining high precision and stability during long-term use and reducing inspection errors caused by wear on the guide rail 133. Additionally, the support frame 122 is equipped with a light source system consisting of multiple LED light sources arranged in a ring or strip pattern, providing uniform and sufficient illumination for the power strip. LED light sources offer advantages such as high luminous efficiency, long lifespan, and energy saving, meeting the needs of continuous long-term inspection. The light intensity and angle of the light source system can be adjusted according to the appearance characteristics of the power strip and inspection requirements. For example, for power strips with smooth surfaces, a higher light intensity and a smaller incident angle can be used to highlight minor surface defects; for power strips with rough or textured surfaces, a lower light intensity and a larger incident angle can be used to avoid reflections and shadows, improving image quality.
[0031] To reduce interference from ambient light, the light source system is also equipped with a light shield, which can effectively block external light from entering the detection area and ensure the stability of the detection environment.
[0032] Example 2, as follows Figures 5-9 As shown, the mounting bracket 131 is equipped with a linkage module for use with the induction motor 124. The linkage module consists of a connecting component 2, a pressurizing structure 3, and a connecting mechanism 4. The pressurizing structure 3 includes a pressurizing cylinder 31, inside which a pressurizing piston 32 is installed. A push rod 33 extending outward is fixed to the bottom side of the pressurizing piston 32. There are two pressurizing structures 3, and the push rods 33 in the two pressurizing structures 3 are respectively connected to the connecting component 2 and the CCD detection probe 132. Specifically, the connecting component 2 includes a horizontal arm 21 and a vertical arm 22. The horizontal arm 21 and the vertical arm 22 are hinged on opposite sides, and their opposite sides are respectively connected to a rotating shaft and the end of one of the push rods 33. It should be noted that the rotating shaft of the detection stage 123 is connected to the push rod 33 of the first pressurizing structure 3 through the connecting component 2, and the two pressurizing structures 3 are linked through the closed pipeline tee pipe 35 and the connecting pipe 36, which ultimately drives the second push rod 33 connected to the CCD detection probe 132. By strictly binding and linking the flip angle of the detection stage 123 with the lifting height of the CCD detection probe 132, the flipping is the same as the focusing, which fundamentally ensures the best imaging distance between the camera and the product at any angle.
[0033] In this embodiment, a three-way pipe 35 is installed between the two pressurizing cylinders 31, and a connecting pipe 36 connected to the guide rail 133 is installed at the other end of the three-way pipe 35. A connecting plate 34 is installed at the end of the push rod 33 away from the connecting assembly 2, and the bottom end of the connecting plate 34 is connected to the guide rail 133. The pressure control or linkage function related to the guide rail 133 is realized through the connection of the connecting pipe 36 to the guide rail 133. At the same time, according to the function of the connecting mechanism 4, the pressurizing structure 3 connected to the connecting assembly 2 can perform liquid delivery or air blowing functions, further increasing the applicability of the structure. Specifically, the pressurizing structure 3 is installed on the top side of the support frame 122. Check valves are provided on both the three-way pipe 35 and the pressurizing piston 32.
[0034] To achieve different detections, the connecting mechanism 4 includes a mounting platform 41 mounted on the outer surface of the connecting plate 34. Two slides 42 are slidably mounted on the top side of the mounting platform 41. A drive motor 43 is also mounted on the top side of the mounting platform 41. A swing block 46 is fixed on the output shaft of the drive motor 43. The upper and lower ends of the swing block 46 are hinged to the two slides 42 with hinge arms 44. Two clamps 45 are slidably mounted on the outside of the two slides 42. Locking holes 47 that engage with the clamps 45 are opened inside the two push rods 33.
[0035] To achieve synchronous movement of the two clamps 45, the top side of the mounting platform 41 is provided with inclined guide grooves 49. Inside each clamp 45, guide wheels 48 are installed that roll in cooperation with the guide grooves 49, ensuring that the two clamps 45 remain synchronized and precise during movement, improving the accuracy and stability of the inspection. Specifically, guide blocks 421 are fixed to the outer walls of both slides 42, and sliding sleeves 451 that slide in cooperation with the guide blocks 421 are fixed to the ends of both clamps 45. In this embodiment, the swing block 46 is driven by the drive motor 43, which pushes the slide 42 via the hinge arm 44. Finally, the clamps 45 are precisely inserted into the locking holes 47 of the push rod 33 using the cooperation of the guide wheels 48 and the inclined guide grooves 49. When different products need to be inspected or maintenance is required, the linkage can be quickly disengaged, allowing the camera to move independently, greatly facilitating debugging and product changeover.
[0036] In this embodiment, the guide block 421 and sliding sleeve 451 ensure the linearity and stability of the movement of the slide table 42 and the clamp 45. The inclined guide groove 49 converts the horizontal movement of the slide table 42 into a combined horizontal and vertical movement of the clamp 45 via the guide wheel 48, ultimately achieving centripetal clamping and insertion. This ensures that the four clamps 45 can synchronously and accurately lock into the locking holes 47, avoiding jamming or unilateral force. It also achieves linkage between the connecting mechanism 4 and the pressure boosting structure 3. Furthermore, through the setting of the connecting mechanism 4 and the linkage with the pressure boosting structure 3, the CCD detection probe 132 can be raised and lowered according to the rotation of the detection stage 123 to adapt to different detection needs. This design is convenient and highly flexible. When different products need to be detected or maintenance is required, the linkage can be quickly disengaged, allowing the camera to move independently. This flexible design greatly facilitates equipment debugging and changeover operations, reduces the time and effort required for debugging and changeover, improves production efficiency, reduces production costs, and enables the equipment to better adapt to diverse production needs.
[0037] Combined with appendix Figures 1-9 The working principle of the above embodiments is as follows: The connector to be tested is placed on the feeding station 173. Since the feeding station 173 has two feeding areas, it can achieve one station feeding while the other station is testing, alternating in a cycle to improve efficiency. The rotary motor 172 starts and rotates the feeding station to the gripping position. The linear module 14 drives the gripping device 16 to move above the feeding station 173. The lifting cylinder 163 descends and the suction nozzle 164 picks up a connector. Then the lifting cylinder 163 rises and the linear module 14 drives the gripping device 16 to move above an empty testing platform 123. The lifting cylinder 163 descends and the suction nozzle 164 breaks the vacuum, placing the connector on the testing platform 123.
[0038] The circular stage 121 achieves 360-degree continuous rotation drive through the air cushion slip ring 125 at the bottom, rotating the detection stage 123 carrying the power strip stepwise to directly below the CCD detection probe 132. The induction motor 124 starts, driving the detection stage 123 to flip to a specific angle. At the same time, the rotating shaft of the detection stage 123 pulls or pushes the push rod 33 connected to it through the connecting component 2. Through the pressure boosting piston 32 and the connecting pipe, the pressure is transmitted to another pressure boosting structure 3, thereby driving the push rod 33 and the connecting plate 34 connected to the CCD detection probe 132. The CCD detection probe 132 achieves precise synchronous lifting and lowering along the guide rail 133. The CCD detection probe 132 takes pictures and detects the power strip at this angle. Then, the induction motor 124 drives the detection stage 123 to flip to the next angle, and the camera lifts and lowers synchronously again for detection. This process is repeated until all preset angles are detected.
[0039] After the inspection is completed, the circular platform 121 continues to rotate, sending the inspected plug-in to the unloading position. The grabbing device 16 grabs the plug-in from the inspection platform 123 according to the inspection result, whether it is qualified or unqualified, and places it into the corresponding material tray 15. The three material trays 15 can be used to store qualified products, unqualified products or products to be re-inspected, respectively. The lifting structure at the bottom of the material tray 15 can compensate for the height change of the material tray 15 caused by the increase of parts, ensuring that the grabbing device 16 can accurately reach the position every time.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
