Description
Technical Field
[0001] The invention belongs to the technical field of FPC / FPCA and other product inspections, and specifically relates to a single-pcs product appearance defect inspection device for incoming materials from a tray carrier. Background Art
[0002] Tray carriers (often referred to as Tray Carriers or Tray Loaders) are devices used to carry, transport and organize products during production and logistics. They are widely used in industries such as electronics manufacturing, semiconductor production, and food processing to improve production efficiency and ensure product safety. Tray carriers are designed to carry single products (i.e., "single pcs" products) and transport them through production lines, inspection processes, or logistics systems. They can neatly organize single products on the carrier to prevent collisions or damage during transportation and handling. As key equipment in production and logistics, tray carriers play an important role in ensuring product quality and production efficiency.
[0003] Generally, the quality of products after production needs to be guaranteed to meet standards after multiple steps of processing. At this time, it is necessary to inspect their appearance to ensure quality. The existing single-pcs product appearance defect inspection equipment with incoming trays performs in-situ inspection. The products in the entire tray are inspected together, resulting in low accuracy during product inspection. At the same time, the reverse side of the product cannot be inspected, resulting in a high leakage rate, which greatly reduces the working performance of the appearance defect inspection equipment. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a single pcs product appearance defect detection device for incoming materials from a tray carrier.
[0005] The technical solution adopted to solve the above technical problems is: a single pcs product appearance defect detection device for incoming materials from a tray carrier, comprising a feeder, a detection machine is fixedly connected to one side of the X-axis of the feeder, and a feeder is installed on one side of the X-axis of the detection machine;
[0006] The loading machine is provided with an internal loading mechanism, the detection machine is provided with an internal detection mechanism, and the unloading machine is provided with an internal unloading mechanism.
[0007] Furthermore, the internal loading mechanism includes a full bin, which is located on one side of the Y-axis, an empty bin is fixedly connected to one side of the Y-axis of the full bin, a extraction tray body is provided on the top of the empty bin, a first extraction tray material taking module is provided on the top of the full bin, two groups of cylinders are provided on one side of the X-axis of the empty bin and the full bin, a secondary positioning module is provided on the top of the two groups of cylinders, a first four-axis robot module is provided on one side of the X-axis of the empty bin and the full bin, the empty bin and the full bin are arranged side by side, the empty bin and the full bin are mirror-displayed along the Y-axis, and a cylinder is provided inside the first four-axis robot module.
[0008] Through the above technical solution, when in use, it is composed of two full bins and an empty bin on both sides, and the extraction tray body is lifted up. The full extraction tray body on the full bin takes out the extraction tray body lifted up and puts it on the transfer module. Before placing the tray, if there is an empty extraction tray body that has taken out the product on the transfer module, the front blocking cylinder will drop, and the empty extraction tray body will be pushed into the empty bin. The full extraction tray body put down by the material taking module will be moved to the robot material taking position after secondary positioning, and the product will be sucked out from the full extraction tray body and put into the detection machine. The secondary positioning module is composed of two groups of cylinders, one group locates the long side of the extraction tray through the rocker mechanism, and one group directly locates the short side of the extraction tray by pushing the cylinder forward. The other two are the reference sides, thereby completing the secondary positioning of the extraction tray, improving the stability and accuracy of the robot taking materials, and improving the utilization rate of the whole machine. Then the empty extraction tray body drops.
[0009] Furthermore, the internal detection mechanism includes a bottom plate fixedly connected to the inner wall of the detection machine, two transfer platforms are fixedly connected to one side of the X-axis of the top of the bottom plate, a positioning and correction camera is arranged between the two transfer platforms, a reverse detection module is arranged on one side of the X-axis of the positioning and correction camera, reverse material picking modules are arranged on both sides of the Y-axis of the reverse detection module, a front detection platform is fixedly connected to the top of the bottom plate, the front detection platform, a front detection module is arranged at the middle end of the top of the bottom plate, and material picking and placing lifting modules are arranged at the bottom of the two transfer platforms, and two A product transfer and translation module is provided on one side of the X-axis of the transfer platform, a vacuum suction nozzle group for picking up and discharging materials is provided on one side of the X-axis of the two front detection platforms, and a picking up and discharging lifting cylinder group is provided on one side of the X-axis of the vacuum suction nozzle group. The two transfer platforms are composed of vacuum adsorption platforms, and the two positioning and correction cameras are respectively located at the front and rear of the detection machine. The two reverse detection modules are composed of XY two-axis servo screw modules and a camera Z-axis stepping module, and the front detection module is composed of an X-axis servo screw module and a camera Z-axis stepping module.
[0010] Through the above technical scheme, the two transfer platforms are composed of vacuum adsorption platforms. The products are placed alternately on the two transfer platforms through the manipulator. The two positioning and correction cameras correspond to the loading and correction positioning, and the unloading positioning, respectively. The two reverse detection modules are distributed in a mirror image. This module takes the product out of the transfer platform and moves it to the reverse material collection module. After the reverse detection is completed, the product is moved and placed on the front detection module. The front detection platform and the front detection module X-axis and its own Y-axis move to perform four-degree-of-freedom movement in the plane, so as to perform front detection. After completion, it moves to the unloading position and waits for the unloading machine to pick up the material. The dual-channel detection machine can speed up the detection speed of the whole machine. While detecting in one channel, loading and unloading can be carried out in another channel. The same is true for unloading, which can effectively save the pause time of the mechanical structure of the equipment and make the whole machine action more coherent. In addition, the two sets of cameras for positive and negative detection are mutually compatible in the two channels, which can effectively eliminate imaging errors, and the software program is more streamlined, which is convenient for personnel to debug and operate.
[0011] Furthermore, the internal mechanism of the material unloading includes an NG bin opened in one of the mirror-image-arranged unloading machines, an OK bin opened in the other unloading machine, a full and empty extraction tray bin is fixedly connected to one side of the Y-axis of the OK bin, a second four-axis robot module is installed between the NG bin and the top of the OK bin, a extraction tray transfer module is provided on the top of the OK bin, a second extraction tray picking module is provided on the top of the full and empty extraction tray bin, the OK bin and the full and empty extraction tray bin are arranged in parallel, and a cylinder is provided inside the second four-axis robot module.
[0012] Through the above technical solution, the internal mechanism of unloading is the same as that of loading, but the definition mode is different. The material bin is composed of an OK material bin on one side and an NG material bin on the other side and an empty extraction tray material bin. Its function is to lift up the empty extraction tray and lower the extraction tray in the OK bin or NG bin. The second extraction tray material taking module is distributed in a mirror image, and the material bin position of the empty extraction tray takes out the above-mentioned extraction tray that has been lifted into place and places it on the extraction tray transfer module. Before placing the tray, if there is a full extraction tray with products on the extraction tray transfer module, the front blocking cylinder will drop and push the full extraction tray into the OK bin or NG bin material bin. The extraction tray transfer module is distributed in a mirror image, and the full extraction tray lowered by the second extraction tray material taking module is re-positioned and moved to the robot extraction position. The second four-axis manipulator module sucks the product out of the inspection machine and puts it into the extraction tray in the OK bin or NG bin.
[0013] The beneficial effects of the present invention are as follows: (1) The present invention designs an internal loading mechanism, an internal detection mechanism and an internal unloading mechanism. The detection internal mechanism is usually faster than manual detection, and a large number of products can be processed in a short time, which significantly improves the detection efficiency of the production line. At the same time, under the detection of multiple probes, the overall detection accuracy is high and the error rate is low, thereby greatly improving the detection strength of the product; (2) The present invention designs an internal loading mechanism and an internal unloading mechanism, which can achieve an automated feeding effect when the product is loaded and unloaded, greatly improving the detection efficiency of the PCS product appearance defect detection equipment; (3) The present invention designs an internal detection mechanism. After the product successfully enters the device, it is simultaneously detected through two detection lines, and the front and back sides of the product can be detected separately, which can replace traditional disk inspection and manual front and back defect detection of products, and has the advantages of high efficiency, high accuracy, low error rate, and high utilization rate.
