Description

Technical Field

[0001] This invention specifically relates to a fully automated prism ink-dip device, belonging to the technical field of prism ink-dip devices. Background Technology

[0002] In the manufacturing process of prisms, the edges of the prisms need to be coated with ink. In the prism edge ink coating technology, apart from the inefficient manual ink coating method, the following two methods are mainly used: First, a single prism is vacuum-adsorbed using a clamp, and then the angle of the prism is rotated so that the ink-coating needle applies ink to the corresponding edge. By adjusting the rotation angle, different edges of the prism can be coated with ink. Second, a single prism is placed in a prism clamping mechanism. A scraping mechanism is set above the prism clamping mechanism. The scraping mechanism includes a screen, also known as a silk screen, on which a scraper assembly is set. The scraper assembly is electrically connected to a servo motor and moves horizontally under the control of the servo motor. The screen is set with a pattern forming area corresponding to the position of the prism clamping mechanism. The scraper assembly scrapes the ink through the screen and prints it onto the surface of the prism. The above two methods have the following technical problems: both are ink coating schemes for a single prism, resulting in low ink coating efficiency and high requirements for the positioning of the individual prisms; failure to meet the requirements will affect the ink coating position and effect. In addition, the second method of ink coating via a stencil can only coat the fixed edges of the prism, which has poor applicability to products of various specifications. For example, Chinese Patent Publication No. CN111169157A discloses a prism edge ink coating fixture and prism edge ink coating device, which can alleviate the technical problems of low ink coating efficiency when ink coating the edges of prisms, where only a single prism is coated at a time, and the stencil ink coating method can only coat the fixed edges of the prism, which has poor applicability to products of various specifications. However, this device is not highly automated, and manual intervention is required for coating loading and unloading. Summary of the Invention

[0003] To address the aforementioned issues, this invention proposes a fully automated prism ink-dipping device that enables automatic feeding, screen printing transfer, ink-dipping printing, and material collection, allowing the prism to achieve fully automated ink-dipping throughout the entire process.

[0004] The prism ink-dipping fully automated equipment of the present invention includes an equipment chassis, an ink-dipping platform is provided inside the equipment chassis, and a stacking and feeding assembly, a mid-section conveying assembly, a stacking and unloading assembly, an ink-dipping robot assembly, a rotary table assembly, an ink-cleaning robot assembly, a screen lifting assembly, an ink-filling gantry assembly, and a transfer tray are arranged on the ink-dipping platform.

[0005] The middle section conveying component is connected to the stacking loading component and the stacking unloading component at both ends, respectively.

[0006] The rotary turntable assembly is located on the side of the middle section conveyor assembly;

[0007] The ink-dipped robotic arm assembly is connected above the rotating position of the middle section conveyor assembly and the rotary turntable assembly;

[0008] The screen lifting assembly and the ink-dispensing robotic arm assembly are oppositely arranged above the rotating position of the rotary table assembly; the ink-filling gantry assembly is arranged directly above the screen lifting assembly;

[0009] The travel direction of the middle section conveyor component is perpendicular to the travel direction of the ink cleaning robot component;

[0010] The transfer tray is transferred between the stacking loading component, the intermediate conveying component, and the stacking unloading component;

[0011] The transfer tray is equipped with multiple rows of fixtures; multiple triangular prisms are placed inside the fixtures, and the three sides of the triangular prisms protrude from the outside of the fixtures.

[0012] During operation, 5 to 10 transfer trays are stacked on the stacking and loading assembly. The transfer trays stacked on the stacking and loading assembly are sequentially transferred out of the stacking and loading assembly from the bottom by the middle section conveyor assembly. The middle section conveyor assembly moves the transfer trays forward and triggers the positioner. The middle section conveyor assembly stops and waits for the ink-dipping robot assembly to transfer them. When the ink-dipping robot assembly is transferring, it moves back and forth between the transfer trays above the middle section conveyor assembly and the printing platform of the rotary table assembly. The ink-dipping robot assembly completes the jig handling, flipping and ink-dipping actions on the transfer trays.

[0013] The working process of the rotating turntable assembly is as follows:

[0014] The rotary turntable assembly rotates the printing platform below the screen lifting assembly and the ink filling gantry assembly. The screen lifting assembly presses against the printing platform, and the ink is scraped onto the screen of the screen lifting assembly by the doctor blade and the ink return blade of the ink filling gantry assembly. The printing platform acts as an ink-adhesive medium, and the designed graphic ink layer thickness is transferred to the printing platform through screen printing.

[0015] The printed substrate platform is moved to the inking section via a turntable. The inking robot arm clamps the fixture containing the triangular prism product and places it directly above the printed substrate platform. It then descends to perform the inking operation. After one edge of the triangular prism product is inked, the inking robot arm moves upward and flips the fixture to change the edge until all edges of the triangular prism product are inked. The inking robot arm then moves upward and detaches from the substrate platform. It returns the fixture to the transfer tray on the intermediate conveyor assembly and sends the inked prisms to the stacking and unloading assembly for stacking.

[0016] After the transfer ink layer on the printing platform is contaminated with ink, the rotary turntable assembly rotates the printing platform to the ink cleaning robot assembly for ink cleaning. Excess ink is scraped off, and the rotary turntable assembly rotates the ink-cleaned printing platform to below the screen lifting assembly and the ink filling gantry assembly for re-transfer printing.

[0017] Furthermore, the stacking loading assembly and stacking unloading assembly include a frame body, a frame plate fixed to the top surface of the frame body, corner guards provided at the corners of the top surface of the frame plate, and electric conveyor belts provided on both sides of the bottom surface of the frame body. A hydraulic lifting assembly is fixed to the frame body between the two sets of electric conveyor belts via a frame plate. A material tray frame is provided inside the frame plate. The material tray frame is fixed to the lifting end of the hydraulic lifting assembly. Two sets of slide rails are fixed to the top surfaces of the frame plate respectively, and a receiving slide hand is slidably mounted on the slide rails. The bottom of both sides of the transfer tray has slots for engaging with the receiving slide hand. A slide hand hydraulic cylinder is fixed to the top surface of the frame plate between the two sets of slide rails. The slide hand hydraulic cylinder is fixed to the receiving slide hand.

[0018] Stack 5 to 10 transfer trays on the tray rack and limit the corners of the transfer trays with corner guards. When the transfer trays need to be transferred, the hydraulic lifting assembly drives the tray rack to press against the bottom transfer tray. Then, the hydraulic cylinder of the sliding hand drives the receiving sliding hand to exit the slot of the transfer tray. At this time, the hydraulic lifting assembly drives the tray rack to descend. The tray rack passes between two sets of electric conveyor belts, so that the bottom transfer tray is pressed against the top surface of the two sets of electric conveyor belts. Then, the hydraulic cylinder of the sliding hand drives the receiving sliding hand to engage in the slot of the second to last transfer tray. At this time, the transfer tray is sent out of the stacking and loading assembly and into the middle conveying assembly by the two sets of electric conveyor belts.

[0019] After the prisms on the transfer tray have completed their ink application, they are fed into the electric conveyor belt of the stacking and unloading assembly. Then, the hydraulic lifting assembly drives the tray frame to rise, thus lifting the transfer tray on the electric conveyor belt so that it is in contact with the bottom surface of the bottom transfer tray on the stacking and unloading assembly. Next, the hydraulic cylinder of the sliding handle drives the receiving sliding handle to exit the slot of the transfer tray. At this time, the hydraulic lifting assembly drives the tray frame to continue to rise. Then, the hydraulic cylinder of the sliding handle drives the receiving sliding handle to engage with the slot of the bottom transfer tray. This temporarily stores the transfer tray containing the prisms after ink application, awaiting retrieval.

[0020] Furthermore, the mid-section conveying assembly includes a conveying bracket, with electric transfer belts installed on both sides inside the conveying bracket; docking guide rails are fixed to both ends of the conveying bracket via seat plates; the docking guide rails are embedded between two sets of electric conveyor belts; the top surfaces of the docking guide rails, the electric transfer belts, and the electric conveyor belts are flush. When the transfer tray on the stacking loading assembly is sent to the electric transfer belt, it is conveyed forward by the electric transfer belt until the positioner of the mid-section conveying assembly is triggered, waiting for the prism to undergo ink dot printing. The transfer tray storing the ink-dot printed prism is sent to the stacking unloading assembly for storage, waiting for the transfer tray to be retrieved.

[0021] Furthermore, the ink-dispensing robotic arm assembly includes a first Y-axis electric slide connected above the intermediate conveyor assembly via a support column; the travel direction of the first Y-axis electric slide is perpendicular to the travel direction of the intermediate conveyor assembly; a first Z-axis electric slide is fixed on the slider of the first Y-axis electric slide; a fixture clamping and flipping module is fixed on the slider of the first Z-axis electric slide; when the fixture clamping and flipping module moves to the material tray position, the first Z-axis electric slide drives the fixture clamping and flipping module to descend and pick up the material. The clamping head of the fixture clamping and flipping module clamps and picks up the material from the fixture. After picking up the material, it moves to a safe height and then moves back to directly above the printing platform. Next, the fixture clamping and flipping module descends to perform the ink application operation. The equilateral triangular prism is placed vertically downwards inside the fixture. During ink application, the bottom edge of the triangular prism is repeatedly dipped in ink about 2 to 4 times. After completion, the fixture clamping and flipping module moves upwards, drives the clamping head to rotate so that the other edge is facing down, and performs the ink application step according to the above steps. After completion, the last edge is rotated downwards according to the above steps and the ink application action is performed. In this way, the product with 10 prisms in the fixture is completed. After the fixture clamping and flipping module returns to the safe height, the fixture is placed back into the material tray; a new fixture is then clamped.

[0022] Furthermore, the rotary turntable assembly includes a cam divider driven by a motor, and a rotary turntable is fixed to the rotating end of the cam divider; multiple printing platforms are equally divided and fixed on the top surface of the rotary turntable; the rotary turntable adopts a four-part turntable; it is responsible for completing the transfer conversion of the printing plate; and it completes the conversion of each station in sequence.

[0023] Furthermore, the ink-cleaning robot assembly includes a first X-axis electric slide fixed above the rotating position of the rotary turntable assembly via a column; a second cylinder support is fixed on the slider of the first X-axis electric slide; a second cylinder is fixed on the second cylinder support, and an ink-cleaning scraper is installed on the telescopic end of the second cylinder; an ink receiving plate is fixed to the outer edge of the rotating position of the rotary turntable assembly via the column.

[0024] After the transfer layer of the printing platform has completed the edge ink application, it is sent to the bottom of the ink cleaning robot assembly. Then, the ink cleaning blade is driven to move downward by the second cylinder, and the second cylinder and the ink cleaning blade are driven to clean the ink along the straight direction of the fixture by the first X-axis electric slide, thereby cleaning the ink on the top surface of the printing platform.

[0025] Furthermore, the screen lifting assembly includes a second Z-axis electric slide fixed to the outside of the rotary turntable assembly; a lifting bracket is fixed on the slider of the second Z-axis electric slide, a screen clamp is fixed on the lifting bracket, and a screen is clamped and fixed on the screen clamp, the screen being located above the rotation position of the rotary turntable assembly; the ink filling gantry assembly includes a second Y-axis electric slide fixed to the outside of the second Z-axis electric slide by a support column; a first cylinder support is fixed on the slider of the second Y-axis electric slide, a first cylinder is fixed on the first cylinder support, and an ink filling assembly is installed on the telescopic end of the first cylinder; after the prism completes ink cleaning, it rotates to be directly below the screen lifting assembly and the ink filling gantry assembly, then the second Z-axis electric slide descends to drive the screen to press against the top surface of the printing platform, then the first cylinder drives the ink filling assembly to press against the top surface of the screen, and the second Y-axis electric slide drives the ink filling assembly to perform one reciprocating motion on the screen, thereby scraping and returning ink to the screen; thus completing the transfer of ink on the printing platform.

[0026] Furthermore, the ink filling assembly includes a blade holder, on which a doctor blade and a return blade are mounted.

[0038] Example 1:

[0039] like Figures 1 to 10 The prism ink-dipping fully automated equipment shown includes a machine housing 1, an ink-dipping platform 2 is provided inside the machine housing 1, and a stacking and feeding assembly 3, a mid-section conveying assembly 4, a stacking and unloading assembly 5, an ink-dipping robot assembly 6, a rotary table assembly 7, an ink-cleaning robot assembly 8, a screen lifting assembly 9, an ink-filling gantry assembly 10, and a transfer tray 11 are arranged on the ink-dipping platform 2.

[0040] The middle section conveying component 4 is connected to the stacking loading component 3 and the stacking unloading component 5 at its two ends, respectively.

[0041] The rotary turntable assembly 7 is located on the side of the middle section conveyor assembly 4;

[0042] The ink-dipped robotic arm assembly 6 is connected across the rotation position of the middle section conveyor assembly 4 and the rotary turntable assembly 7;

[0043] The screen lifting assembly 9 and the ink-dipping robotic arm assembly 6 are oppositely arranged above the rotation position of the rotary turntable assembly 7; the ink-filling gantry assembly 10 is arranged directly above the screen lifting assembly 9;

[0044] The travel direction of the middle section conveyor component 4 is perpendicular to the travel direction of the ink cleaning robot component 8;

[0045] The transfer tray 11 is transferred between the stacking loading component 3, the middle section conveying component 4 and the stacking unloading component 5;

[0046] The transfer tray 11 is equipped with multiple rows of fixtures; multiple triangular prisms are placed inside the fixtures.

[0047] During operation, 5 to 10 transfer trays 11 are stacked on the stacking and loading assembly 3. The transfer trays 11 stacked on the stacking and loading assembly 3 are sequentially transferred out of the stacking and loading assembly 3 from the bottom by the middle section conveyor assembly 4. The middle section conveyor assembly 4 moves the transfer trays 11 forward to trigger the positioner, and the middle section conveyor assembly 4 stops, waiting for the ink-dipping robot assembly 6 to transfer them. When the ink-dipping robot assembly 6 transfers, it moves back and forth between the transfer trays 11 above the middle section conveyor assembly 4 and the printing platform 73 of the rotary turntable assembly 7. The ink-dipping robot assembly 6 completes the jig handling, flipping and ink-dipping actions on the transfer trays 11; and then sends them into the printing platform 73.

[0048] The working process of the rotating turntable assembly is as follows:

[0049] The rotating turntable assembly 7 rotates the printing platform 73 below the screen lifting assembly 9 and the inking gantry assembly 6. The screen lifting assembly 7 presses against the printing platform 73, and the squeegee and return blade of the inking gantry assembly 6 scrape ink onto the screen of the screen lifting assembly 7. The printing platform 73 acts as an ink-adhesive medium, and the designed image and ink layer thickness are transferred to the printing platform 73 through screen printing. During screen printing, the basic principle of ink permeability is used, where the mesh openings of the image area of ​​the screen printing plate allow ink to pass through, while the mesh openings of the non-image area do not. During printing, ink is poured into one end of the screen printing plate, and the squeegee and return blade apply a certain pressure to the ink area of ​​the screen printing plate (screen) while moving towards the other end of the screen printing plate. During the movement, the ink is squeezed from the mesh openings of the image area by the squeegee onto the printing platform 73. On the printing surface (substrate), the ink's viscosity keeps the printing edge fixed within a certain range. During printing, the squeegee remains in line contact with both the screen printing plate and the substrate. This contact line moves with the squeegee. Because a certain gap is maintained between the screen printing plate and the substrate, the screen printing plate generates a reaction force on the squeegee through its own tension. This reaction force is called the rebound force. Due to the rebound force, the screen printing plate and the substrate only maintain a moving line contact, while other parts of the screen printing plate remain detached from the substrate. This causes the ink to break apart from the screen, ensuring dimensional accuracy and preventing smudging of the substrate. When the squeegee and return blade have scraped across the entire surface and are lifted, the screen printing plate also lifts, gently scraping the ink back to its initial position. This completes one printing transfer process.

[0050] The printed substrate 73 is moved to the inking section via the turntable assembly 7. The inking robot assembly 6 holds the fixture containing the triangular prism product and places it directly above the printed substrate 73. Then, it moves downward to perform the inking operation. After one edge of the triangular prism product is inked, it moves upward via the inking robot assembly 6 and flips the fixture to change the edge until the inking robot assembly 6 has completed the inking of all edges of the triangular prism product. The inking robot assembly 6 then moves upward to detach from the substrate and returns the fixture to the transfer tray 11 on the intermediate conveyor assembly. The intermediate conveyor assembly then sends the inked prism to the stacking and unloading assembly for stacking.

[0051] After the transfer ink layer on the printing platform 73 is contaminated with ink, the rotary turntable assembly 7 rotates the printing platform 73 to the ink cleaning robot assembly 6 for ink cleaning. Excess ink is scraped off, and the rotary turntable assembly 7 rotates the ink-cleaned printing platform 73 to below the screen lifting assembly 9 and the ink filling gantry assembly 10 for re-transfer printing.

[0052] After the product with multiple prism fixtures has finished working, the ink-dipped robot arm assembly 6 returns to a safe height and is placed back into the transfer tray 11. The printed steel plate rotates to the de-inking section. At the same time, two working units are operating: 1. The ink-dipped robot arm assembly 6 picks up a new fixture. 2. The screen printing is repeated on the second steel plate. The ink removal robot in the de-inking section scrapes off the excess ink from the steel plate and collects it in the waste box. This process is repeated for all four steel plates. The ink-adhesive robot 6 continuously completes the work of 16 product jigs on one tray, picking up two jigs at a time. One tray is picked up and operated 8 times. The de-inking section removes ink using the same steps. After one tray is completed, it is transported to the stacking and unloading component 5 via the intermediate conveyor component 4. After five trays are completed in the material tower, the photosensitive element indicates that the material tower is full. The completed tray is then removed and moved to the next process, thus completing the equipment operation. The stacking and loading component 3 simultaneously feeds the ink-adhesive work position via the intermediate conveyor component 4, operating at the same time as the unloading conveyor.

[0053] The stacking loading assembly 3 and stacking unloading assembly 5 include a frame body 31. A frame plate 32 is fixed to the top surface of the frame body 31. Corner guards 33 are provided at the corners of the top surface of the frame plate 32. Electric conveyor belts 34 are provided on both sides of the bottom surface of the frame body 31 and the frame plate 32. A hydraulic lifting assembly 35 is fixed between the two sets of electric conveyor belts 34 through a frame plate. A material tray frame 36 is provided on the inner side of the frame plate 32. The material tray frame 36 is fixed to the lifting end of the hydraulic lifting assembly 35. Two sets of slide rails 37 are fixed to the two sides of the top surface of the frame plate 32. A receiving slide handle 38 is slidably mounted on the slide rails 37. The bottom of both sides of the transfer tray 11 has slots 111 that engage with the receiving slide handle 38. A slide handle hydraulic cylinder 39 is fixed between the two sets of slide rails 37 on the top surface of the frame plate 32. The slide handle hydraulic cylinder 39 is fixed to the receiving slide handle 38.

[0054] Five to ten transfer trays 11 are stacked on the tray frame 36, and corner guards 33 limit the corners of the transfer trays 11. When the transfer trays 11 need to be transferred, the hydraulic lifting assembly 35 drives the tray frame 36 to press against the bottom transfer tray 11. Then, the sliding hydraulic cylinder 39 drives the receiving sliding hand 38 to exit the slot 111 of the transfer tray 11. At this time, the hydraulic lifting assembly 35 drives the tray frame 36 to descend. The tray frame 36 passes between two sets of electric conveyor belts 34, so that the bottom transfer tray 11 is pressed against the top surface of the two sets of electric conveyor belts 34. Then, the sliding hydraulic cylinder 39 drives the receiving sliding hand 38 to engage in the slot 111 of the second to last transfer tray 11. At this time, the transfer trays 11 are sent out of the stacking and loading assembly 3 and into the middle conveying assembly 4 by the two sets of electric conveyor belts 34.

[0055] After the prisms on the transfer tray 11 have completed ink application, they are fed into the electric conveyor belt 34 of the stacking and unloading assembly 5. Then, the hydraulic lifting assembly 35 drives the tray frame 36 to rise, thereby lifting the transfer tray 11 on the electric conveyor belt 34 so that the transfer tray 11 is in contact with the bottom surface of the bottom transfer tray 11 on the stacking and unloading assembly 5. Next, the sliding hydraulic cylinder 39 drives the receiving sliding hand 38 to exit the slot 111 of the transfer tray 11. At this time, the hydraulic lifting assembly 35 drives the tray frame 36 to continue to rise. Then, the sliding hydraulic cylinder 39 drives the receiving sliding hand 38 to engage with the slot 111 of the bottom transfer tray 11. Thus, the transfer tray 11 of the prisms after ink application is temporarily stored, waiting to be retrieved.

When the transfer tray 11 on the stacking loading assembly 3 is sent to the electric conveyor belt 42, it is passed forward by the electric conveyor belt 42 until the positioner 44 of the intermediate conveying assembly 4 is triggered, waiting for the prism to be dipped in ink for dot printing. The transfer tray 11 storing the ink-dipped prism is sent to the stacking unloading assembly 5 for storage, waiting for the transfer tray 11 to be retrieved.

[0057] The ink-dipped robotic arm assembly 6 includes a first Y-axis electric slide 61 that is connected above the middle section conveyor assembly 4 via a support column 64; the travel direction of the first Y-axis electric slide 61 is perpendicular to the travel direction of the middle section conveyor assembly 4; a first Z-axis electric slide 62 is fixed on the slider of the first Y-axis electric slide 61; a jig clamping and flipping module 63 is fixed on the slider of the first Z-axis electric slide 62.

[0058] During the ink application process, the first Y-axis electric slide 61 and the middle section conveying assembly 4 work together to enable the fixture clamping and flipping module 63 to position the fixture on the transfer tray 11 in the X and Y directions. After positioning is completed, the slider of the first Z-axis electric slide 62 drives the fixture clamping and flipping module 63 to move down to clamp and flip the fixture, and to apply ink to the edge of the prism.

[0059] The rotating turntable assembly 7 includes a cam divider 71 driven by a motor, and a rotating turntable 72 is fixed to the rotating end of the cam divider 71. Multiple sets of printing platforms 73 are equally divided and fixed on the top surface of the rotating turntable 72. The printing platforms 73 are made of printing steel plates. The rotating turntable 72 is a four-part turntable, responsible for completing the conversion of the printing steel plates. The conversion is carried out by counterclockwise rotation, and the conversion of each station is completed in sequence. The printing steel plates serve as ink-dipping media. The equipment is equipped with four such steel plates, which are placed on the disc and fixed in a cross shape. They can be individually parallelized and corrected.
