DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0040] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present application are only for the convenience of clear description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship is also considered as the implementation scope of the present application without substantial change of the technical content.

[0041] Reference Figures 1-11 A ceramic substrate visual detection device, comprising: a loading and unloading bin device 1, two symmetrically arranged docking moving assemblies 2, a front and back surface detection camera device 3 and a code printing device 4, wherein the code printing device 4 is provided with a negative pressure dust removal assembly 5, and the negative pressure dust removal assembly 5 is fixedly installed in the middle part of the code printing device 4.

[0042] The negative pressure dust removal assembly 5 comprises a mounting ring pipe 51, a gas compression module 52, an air outlet pipe 53, two top blocks 54 and two bottom covers 55, the mounting ring pipe 51 is a rectangular ring pipe, and one side short edge is fixedly installed on the side edge of the coding device 4, the gas compression module 52 is fixedly installed in the short edge of the mounting ring pipe 51 away from the coding device 4, the air outlet pipe 53 is fixedly communicated on the other side of the mounting ring pipe 51, and two gas flows from the two sides of the gas compression module 52 to the air outlet pipe 53 are formed in the mounting ring pipe 51, the two top blocks 54 are fixedly connected to the inner top wall of the long edge of the mounting ring pipe 51, and the two bottom covers 55 are fixedly connected to the inner bottom of the long edge of the mounting ring pipe 51.

[0043] The two sides of the top block 54 and the bottom cover 55 are provided with arc-shaped edges, and a flow guide space is formed between the top block 54 and the bottom cover 55, a Venturi channel is formed between the two sides of the top block 54 and the bottom cover 55 and the flow guide space, a dust suction port 8 is arranged at the upper end of the bottom cover 55, and a plurality of porous suction nozzle arrays 9 are arranged below the long edges of the two sides of the mounting ring pipe 51.

[0044] In the embodiment of the application, the conventional single suction port is easy to form a "dead angle" of air flow on the surface of the substrate, air blowing may cause secondary pollution, and small particles cannot be removed, so the application uses a negative pressure dust removal mode for efficient dust removal. When working, the gas compression module 52 (the gas compression module 52 belongs to the prior art and is commonly used in the field of negative pressure adsorption) is started, two gas flows are formed in the mounting ring pipe 51 and flow from the two sides of the gas compression module 52 to the air outlet pipe 53. When the gas flow passes through the Venturi channel, due to the change of the cross section of the channel, the flow rate increases and the pressure decreases, and negative pressure is generated at the dust suction port 8 and the porous suction nozzle array 9, so as to adsorb the dust on the surface of the ceramic substrate. The application utilizes the Venturi effect to enhance the local negative pressure and improve the dust removal efficiency, and is especially suitable for small particles. At the same time, the negative pressure suction force is uniformly distributed to cover the entire surface of the substrate, and there is no dead angle for dust removal.

[0045] At the same time, through the cooperative work of the feeding and discharging bin device 1, the butt joint transfer assembly 2 and the visual detection module, automatic feeding, overturning, detection, coding and discharging of the ceramic substrate are realized, the production efficiency is greatly improved, and manual intervention is reduced.

[0046] The preferred technical solutions in the embodiment are as follows:

[0047] Referring to Figure 2 , the feeding and discharging bin device 1 comprises a mechanical hand transfer assembly 101, a collection assembly 102, a feeding assembly 103 and a tray transfer assembly 104, the collection assembly 102 is arranged below the mechanical hand transfer assembly 101, the feeding assembly 103 is arranged on the side edge of the collection assembly 102, and the tray transfer assembly 104 is arranged between the collection assembly 102 and the feeding assembly.

[0048] The ceramic substrate is stacked with the tray and enters the system through the feeding assembly 103, and then a series of detection and coding processes are performed. After the substrate completing the detection and coding processes is transferred to the unloading position by the docking transfer assembly 2, the robot transfer assembly 101 sorts the product to the corresponding (OK / NG) collection tray according to the detection result, and the empty tray is recycled.

[0049] Referring to Figure 3 , the docking transfer assembly 2 comprises a transfer rail 21, a lifting cylinder 22, an electric clamp jaw 23 and a turnover table 24. The two transfer rails 21 are symmetrically arranged, the lifting cylinder 22 is slidingly arranged on the transfer rail 21, the turnover table 24 is rotatably installed on the upper end of the lifting cylinder 22, and the electric clamp jaw 23 is fixedly connected to the rotating end of the turnover table 24.

[0050] After the product is corrected, it is sent to the docking transfer assembly 2 by the robot transfer assembly 101, and the ceramic substrate is clamped by the lifting cylinder 22, the turnover table 24 and the electric clamp jaw 23. At the same time, the lifting cylinder 22 moves on the transfer rail 21 to transfer the ceramic substrate to be detected under the front and back detection camera device 3. After the detection and coding are completed, the ceramic substrate is transferred to the robot transfer assembly 101 by the transfer rail 21, and the unloading of the ceramic substrate is completed.

[0051] After the lifting cylinder 22 moves along the transfer rail 21 and the electric clamp jaw 23 clamps the product, the turnover table 24 rotates 180° to realize the switching of the front and back of the product. The whole process is controlled by PLC, which has high precision and fast response. The two docking transfer assemblies 2 are symmetrically arranged to support parallel processing and improve throughput. The electric clamp jaw 23 is suitable for different size substrates to avoid damaging the product.

[0052] Referring to Figure 4 , the front and back detection camera device 3 comprises a face array camera assembly 31, a gantry detection transfer assembly 32 and an ion dust removal assembly 33. The gantry detection transfer assembly 32 is erected on the transfer rail 21, the ion dust removal assembly 33 is fixedly connected to the side of the gantry detection transfer assembly 32 close to the feeding and discharging bin device 1, and the face array camera assembly 31 is fixedly installed on the side of the gantry detection transfer assembly 32 close to the coding device 4.

[0053] The ceramic substrate is first pretreated by the ion dust removal assembly 33 to eliminate static electricity on the surface of the substrate before detection, prevent dust interference and improve image quality. Then it enters the vision detection position, and the gantry detection transfer assembly 32 drives the face array camera assembly 31 to move to collect high-resolution images of the front and back of the ceramic substrate. Then the product is turned over by the turnover table 24 for back detection. Through the cooperation of the front and back detection camera device 3, the movable clamp jaw and the turnover table 24, the automatic turnover and detection of the front and back of the ceramic substrate can be quickly completed, thereby improving the detection efficiency.

[0054] Referring to Figure 5 The code printing device 4 comprises a code scanning assembly 41, a laser code printing machine 42 and a lifting adjusting seat 43, the laser code printing machine 42 is fixedly installed at the top end of the lifting adjusting seat 43, and the code scanning assembly 41 is fixedly installed at the side of the lifting adjusting seat 43 close to the front-back surface detection camera device 3.

[0055] When the qualified ceramic substrate is transferred to the code printing position, the dust adhered to the surface of the ceramic substrate during the movement is removed by the negative pressure dust removal assembly 5, and then the code printing is performed on the ceramic substrate by the laser code printing machine 42. The ceramic substrate after the code printing is transferred to the lower side of the code scanning assembly 41 by the docking transfer assembly 2, and the code printing content is verified by the code scanning assembly 41, thereby improving the accuracy and efficiency of the overall processing.

[0056] The design of the lifting adjusting seat 43 can adjust the code printing height according to the thickness of the substrate, adapt to products of multiple specifications, and simultaneously realize the integration of dust removal and code printing, thereby directly integrating the dust removal function at the code printing position, reducing the interval between processes and improving the overall efficiency.

[0057] Referring to Figures 8-9 Two communication channels 10 are formed in the top blocks 54, one end of the communication channel 10 is located at the upper end of the dust suction port 8, and the other end is located at the upper side of the air outlet pipe 53.

[0058] The dust collection assembly 6 is arranged inside the side of the mounting ring pipe 51 close to the air outlet pipe 53, and the dust collection assembly 6 is used to collect the dust introduced into the inside of the mounting ring pipe 51.

[0059] The dust collection assembly 6 comprises two baffle plates 61, a dust collection plate 62 and two J-shaped pipes 63, the two baffle plates 61 are fixedly connected to the bottom of the side of the mounting ring pipe 51 close to the air outlet pipe 53 in a symmetrical manner and are arranged in a spreader shape, the two J-shaped pipes 63 are fixedly connected to the bottom of the two communication channels 10 in a symmetrical manner, and the two arc-shaped edges are arranged away from each other, and the dust collection plate 62 is a reversed V-shaped plate and is fixedly connected to the bottom of the mounting ring pipe 51.

[0060] During the dust removal process, the dust particles adsorbed into the inside of the mounting ring pipe 51 need to be collected and cleaned, in order to efficiently complete the collection of dust, a communication channel 10 is formed on the upper part of the top block 54, thereby forming a negative pressure in the inside of the communication channel 10, thereby causing the end of the J-shaped pipe 63 connected with the communication channel 10 to form a negative pressure adsorption, thereby adsorbing the dust introduced into the inside of the mounting ring pipe 51, adsorbing the dust to the position of the dust collection plate 62, thereby leaving the dust in the collection space between the dust collection plate 62 and the baffle plate 61, completing the collection of dust and facilitating the cleaning of the dust in the later stage.

[0061] A Venturi channel can form two negative pressure ports in the middle, which can complete the adsorption of dust from the outside, and also can complete the collection of dust introduced into the installation ring pipe 51 inside, through the movement of compressed gas, the adsorption and collection of dust can be formed, which reduces the use of structure and has good effect.

[0062] With reference to Figure 10 The bottom cover 55 is internally provided with a scraping assembly 7 for horizontally scraping the porous nozzle array 9.

[0063] The scraping assembly 7 comprises two limiting frames 71, two elastic strips 72, two scraping blocks 73 and a sliding piece 74, the two limiting frames 71 are fixedly connected symmetrically below the bottom cover 55, the sliding piece 74 is slidingly arranged inside the communication channel 10 and is annularly provided with a plurality of air guide ports on the side edge, the two scraping blocks 73 are fixedly and interactively arranged at the bottom of the installation ring pipe 51, and the two elastic strips 72 are fixedly connected at one end to the bottom of the sliding piece 74 and are fixedly connected at the other end to the two scraping blocks 73 through the two limiting frames 71.

[0064] In a long time of work, a large amount of dust will enter the inside of the bottom cover 55, but in the process of adsorption, dust will still fall and adhere to the porous nozzle array 9, causing blockage of the porous nozzle array 9, thereby affecting the cleaning effect on the surface of the ceramic substrate.

[0065] In order to avoid the blockage of the porous nozzle array 9 by dust, when dust removal is not performed, since the elastic strip 72 is made of metal material, the elastic strip 72 remains vertical when not subjected to external force, and the two scraping blocks 73 are close to each other, when compressed air passes through the Venturi channel, negative pressure is generated inside the communication channel 10, causing the sliding piece 74 to be subjected to pressure and slide downward inside the communication channel 10, the sliding piece 74 is arranged in a streamline shape and is provided with a plurality of air guide ports on the side edge for ventilation, to ensure the normal adsorption effect of the dust collection assembly 6, the sliding piece 74 drives the elastic strip 72 to move downward in the process of sliding downward, the elastic strip 72 will move horizontally along the arc-shaped port on the limiting frame 71 with the scraping block 73, thereby scraping the dust above the porous nozzle array 9 by the scraping block 73, to avoid blockage of dust and ensure the adsorption strength of the porous nozzle array 9.

[0066] The scraping assembly 7 can periodically clean the porous nozzle array 9 to prevent blockage, the dust collection assembly 6 can collect dust to reduce the maintenance frequency and prolong the service life of the equipment.

[0067] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
