Description

Technical Field

[0001] The invention relates to the technical field of visual inspection, in particular to a multi-channel component visual inspection device. Background Art

[0002] The existing mobile phone component detection device has the following problems:

[0003] 1. There are many cameras and the cost is high

[0004] Reason: Most mobile phone components are special-shaped products, and the product inspection angles are more. For the traditional handling method, multiple cameras with different installation angles are required to be used in combination, resulting in a large number of cameras and high costs.

[0005] 2. The inspection station is relatively fixed and it is impossible to add inspection items

[0006] Reason: The existing inspection stations are basically designed with fixed angles, and the stations are designed to be compact. If new inspection items need to be added, it is necessary to consider whether the existing stations can meet the requirements. If not, if new inspection stations are to be added, it is necessary to consider whether there is space for the addition.

[0007] 3. The equipment is large in size and difficult to debug and maintain

[0008] Reason: Traditional AOI equipment is generally divided into rotary type or snake type layout. Rotary type equipment is larger in size, and snake type equipment is not easy to maintain;

[0009] 4. Poor equipment versatility

[0010] Reason: Different mobile phone component inspections can be compatible through a set of inspection stations, but due to different inspection angles and different inspection quantities, the layout of the inspection stations varies greatly and cannot be compatible. Summary of the invention

[0011] The technical problem to be solved by the present invention is to provide a multi-channel component visual inspection device to solve the problems of the existing mobile phone component inspection device having a large number of cameras, fixed inspection stations, large equipment size and poor equipment versatility.

[0012] The technical solution adopted by the present invention to solve the technical problem is: a multi-channel component visual inspection device, including a loading bin mechanism, a loading positioning mechanism, a five-axis detection mechanism, a manipulator handling mechanism and a unloading bin mechanism, the rear end of the loading bin mechanism is connected to the front end of the loading positioning mechanism, the rear end of the loading positioning mechanism is connected to the front end of the five-axis detection mechanism, the unloading bin mechanism is arranged at the rear end of the five-axis detection mechanism, and the manipulator handling mechanism is arranged between the five-axis detection mechanism and the unloading bin mechanism.

[0013] The five-axis detection mechanism includes a first detection module and a second detection module. The first detection module is used to detect the front or back side of the mobile phone components, and the second detection module is used to detect the side opposite to the first detection module. Each detection module includes at least one AOI detection component. When there are multiple AOI detection components, the rear end of the previous AOI detection component is connected to the front end of the next AOI detection component, and the rear end of the last AOI detection component is provided with a material unloading and handling component.

[0014] The AOI detection component includes a mounting frame, an X / Z axis motion part, a Y axis motion part, an A / C axis motion part and a visual detection part. The mounting frame is vertically arranged on a table top. The Y axis motion part is arranged on the bottom table top of the mounting frame. The Y axis motion part and the mounting frame are in a cross shape. The A / C axis motion part is arranged on the Y axis motion part. The fixture is arranged on the A / C axis motion part. The Y axis motion part drives the fixture to move by the A / C axis motion part. The X / Z axis motion part is arranged on the back of the mounting frame above the Y axis motion part and consistent with the feeding direction. The visual detection part is arranged on the X / Z axis motion part. The detection lens of the visual detection part is aligned with the direction of the Y axis motion part. The number of detection lenses in the visual detection part is equal to the number of stations on the fixture, and they are arranged one by one. A handling robot is arranged on the front of the mounting frame opposite to the feeding direction, and the handling robot is arranged above the Y axis motion part.

[0015] Furthermore, the first detection module is used to detect the front of the mobile phone components, and the first detection module includes two AOI detection components, which are arranged front and back along the feeding direction, and the rear end of the Y-axis motion part in the first AOI detection component is connected to the front end of the Y-axis motion part in the second AOI detection component;

[0016] The second detection module is used to detect the back side of mobile phone components. The second detection module includes an AOI detection component.

[0017] When the second detection module is arranged at the front end of the first detection module, the rear end of the Y-axis motion part in the AOI detection component of the second detection module is connected to the front end of the Y-axis motion part in the front AOI detection component of the first detection module.

[0018] When the second detection module is arranged at the rear end of the first detection module, the front end of the Y-axis motion part in the AOI detection component of the second detection module is connected to the rear end of the Y-axis motion part in the last AOI detection component of the first detection module.

[0019] Furthermore, there is a distance between adjacent Y-axis moving parts.

[0020] Furthermore, the A / C axis motion part includes a base, and both sides of the base have mounting positions extending vertically upward for a distance, one side mounting position is a drive mounting position for installing a driver, and the other side mounting position is a shaft mounting position for installing a shaft, and a rotating part is rotatably arranged between the two mounting positions, and the top of the rotating part has a connecting hole for connecting to a fixture.

[0021] Furthermore, the number of the connection holes is equal to and corresponds to the number of the jigs, and each jig has a station for placing mobile phone components.

[0022] The beneficial effects of the present invention are that the defects existing in the background technology are solved, and the present invention has the characteristics of a small number of cameras, a large number of detection stations, a small device size and good device versatility;

[0023] Specifically, 1. The number of cameras can be reduced and the cost can be reduced by using a five-axis detection mechanism; the five-axis detection mechanism uses a set of camera light sources to detect defects at different angles of the product;

[0024] 2. By using the five-axis detection mechanism, the corresponding detection process can be changed according to the actual detection needs to increase the detection items, avoiding the problem of adding new detection stations in traditional AOI;

[0025] 3. The layout of linear transport AOI equipment is generally divided into rotary type or snake type layout. The rotary type layout equipment is large in size and cannot meet the layout requirements of some customers for loading and unloading. The snake type layout equipment is not easy to maintain and difficult to debug. The five-axis detection mechanism is now used to reduce the size of the AOI equipment and facilitate debugging in terms of space.

[0026] 4. To detect different mobile phone components, through the five-axis detection mechanism, you only need to replace the corresponding product fixture or increase the number of five axes to achieve universal AOI;

[0027] The present invention effectively reduces the number of cameras and reduces the cost of equipment. Without adding hardware, some inspection items can be added by modifying the inspection process, thereby avoiding the increase in equipment size due to reserved workstations and increasing equipment debugging space, thereby improving the convenience of debugging, improving the versatility of equipment, reducing design workload, and achieving versatility of mobile phone components and equipment by modifying a small amount of fixtures.

DETAILED DESCRIPTION

[0038] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0039] Figures 1 to 9 A multi-channel component visual inspection device shown in the figure includes a loading bin mechanism 1, a loading positioning mechanism 2, a five-axis detection mechanism 3, a robot handling mechanism 4 and a unloading bin mechanism 5. The rear end of the loading bin mechanism 1 is connected to the front end of the loading positioning mechanism 2, the rear end of the loading positioning mechanism 2 is connected to the front end of the five-axis detection mechanism 3, the unloading bin mechanism 5 is arranged at the rear end of the five-axis detection mechanism 3, and the robot handling mechanism 4 is arranged between the five-axis detection mechanism 3 and the unloading bin mechanism 5.

[0040] The five-axis detection mechanism 3 includes a first detection module and a second detection module. The first detection module is used to detect the front side of the mobile phone components, and the second detection module is used to detect the back side of the mobile phone components. The first detection module uses two AOI detection components, and the two AOI detection components are installed front and back along the feeding direction. The rear end of the Y-axis motion part in the first AOI detection component is connected to the front end of the Y-axis motion part in the second AOI detection component, that is, the first AOI detection component and the second AOI detection component are installed front and back; the second detection module uses an AOI detection component, that is, the third AOI detection component. Since the front side or the back side of the mobile phone components is detected first by the user, It is decided by oneself that when the second detection module is arranged at the front end of the first detection module, the rear end of the Y-axis motion part in the third AOI detection component is connected to the front end of the Y-axis motion part in the first AOI detection component; when the second detection module is arranged at the rear end of the first detection module, the front end of the Y-axis motion part in the third AOI detection component is connected to the rear end of the Y-axis motion part in the second AOI detection component, and there is a distance between adjacent Y-axis motion parts 33; the number of AOI detection components in the first detection module and the second detection module can be increased or decreased according to the different components of the mobile phone, and the unloading and handling component 6 is set at the rear end of the last AOI detection component in the first detection module and the second detection module.

[0041] The structure of each AOI detection component is roughly the same, and can be fine-tuned according to the on-site installation environment. Specifically, the AOI detection component includes a mounting frame 31, an X / Z axis motion part 32, a Y axis motion part 33, an A / C axis motion part 34 and a visual detection part 35. The mounting frame 31 is vertically mounted on the table 7, and the Y axis motion part 33 is arranged on the bottom table 7 of the mounting frame 31. The Y axis motion part 33 and the mounting frame 31 form a cross shape. The A / C axis motion part 34 is installed on the Y axis motion part 33, and the A / C axis motion part 34 is arranged on the jig 8. The Y axis motion part 33 drives the jig 8 to move forward and backward along the feeding direction through the A / C axis motion part 34. The A / C axis motion part 34 includes a base 341. Both sides of the base 341 have mounting positions extending vertically upward for a distance. The mounting position on one side is a drive mounting position 342 for driver installation, and the mounting position on the other side is a shaft mounting position 343 for shaft installation. A rotating part 344 is dynamically arranged, and a connecting hole 345 for connecting to a jig 8 is provided on the top of the rotating part 344. The number of the connecting holes 345 is equal to the number of the jigs 8 and corresponds one to one. Each jig 8 has a station 9 for placing mobile phone components. The A / C axis moving part 34 drives the jig 8 to rotate forward and backward at multiple angles in the same direction as the Y axis moving part 33. An X / Z axis moving part 32 is installed on the back of a mounting frame 31 above the Y axis moving part 33 and in the same direction as the feeding direction. A visual inspection part 35 is installed on the X / Z axis moving part 32. The X / Z axis moving part 32 drives the visual inspection part 35 to move up and down and left and right. The inspection lens of the visual inspection part 35 is aligned with the direction of the Y axis moving part 33. The number of inspection lenses in the visual inspection part 35 is equal to the number of stations 9 on the jig 8 and corresponds one to one. A handling robot 36 is arranged on the front of the mounting frame 31 opposite to the feeding direction, and the handling robot 36 is arranged above the Y axis moving part 33.

[0042] The loading bin mechanism 1, loading positioning mechanism 2, robot transport mechanism 4 and unloading bin mechanism 5 are prior arts, and the same applicant has applied for patents before the present application, so the description of the specific structure is omitted.

[0043] When used specifically,

[0044] First, mobile phone components are loaded through the tray in the loading bin mechanism 1, and full trays are stacked manually or mechanically in the loading bin of the loading bin mechanism 1. 25 trays can be stacked at a time, and the trays are transferred to the automatic loading position through the bin tray separation mechanism of the loading bin mechanism 1. After the robot takes the materials, the empty trays are stacked at the unloading position;

[0045] Next, the robot places the mobile phone components in the positioning assembly of the loading and positioning mechanism 2, and the positioning mechanism is as follows: Fig. 9 As shown, it includes a driving unit 10, a track 11 and a positioning member 12. The driving unit 10 drives the fixture 8 to move along the track 11, and stops moving after touching the positioning member 12, so that the mobile phone components are positioned;

[0046] Then, the handling manipulator 36 carries the mobile phone components to the AOI inspection component in the five-axis inspection mechanism 3, and after the inspection is completed, it is carried to the next AOI inspection component. Two front and one back AOI inspection components are set according to the inspection requirements. The AOI inspection component inspects 6 mobile phone components at a time. The mobile phone components are placed in the station 9 of the fixture 8. The motion trajectory is controlled by the board card. The five axes of the AOI inspection component work together to realize the inspection of mobile phone components at all angles.

[0047] Finally, after the inspection is completed, the mobile phone components are transported to the unloading positioning component through the unloading transport component 6. The unloading positioning component is similar to the positioning component in the loading positioning mechanism 2. The unloading robot transports the mobile phone components to the unloading tray corresponding to the unloading bin mechanism 5.

[0048] The above description only describes the specific implementation mode of the present invention. Various examples do not limit the essential content of the present invention. After reading the description, ordinary technicians in the relevant technical field can modify or deform the specific implementation modes described above without departing from the essence and scope of the invention.
