Description

Technical Field

[0001] This invention relates to the field of fuel cell production testing equipment technology, specifically a measuring tool for rapidly detecting the uniformity of SOFC screen printing. Background Technology

[0002] SOFC stands for Solid Oxide Fuel Cell, a third-generation fuel cell. It is an all-solid-state chemical power generation device that efficiently and environmentally converts the chemical energy stored in fuel and oxidant into electrical energy at medium to high temperatures. A single cell consists of an electrolyte, cathode, anode, and connectors, and multiple single cells form a fuel cell stack. In the fuel cell production process, screen printing is a process that prints functional pastes such as electrode materials onto the battery substrate, such as the electrolyte, through a screen to form specific patterns. Due to its advantages of high precision, low cost, and stable process, screen printing technology occupies an important position in the SOFC preparation process and is now widely used in the preparation of electrolytes, anodes, and cathodes of SOFC batteries.

[0026] Example

[0027] Please see Figure 1-7 This invention provides a technical solution: a measuring tool for quickly detecting the uniformity of SOFC screen printing, comprising a conveyor frame 1, a frame 2 fixedly connected to the top of the conveyor frame 1, a screen printing plate 3 fixedly connected inside the frame 2, a waste material interception plate 31 fixedly connected to the back of the screen printing plate 3, the waste material interception plate 31 being vertically adjustable, a negative pressure mounting plate 4 provided at the top of the conveyor frame 1, the negative pressure mounting plate 4 including a plate body 41 located at the top of the conveyor frame 1, a negative pressure seat 42 communicating inside the plate body 41, an opening communicating with the plate body 41 at the top of the negative pressure seat 42, a one-way valve provided on the front of the plate body 41, a linear motor frame 5 fixedly connected to the top of the frame 2, a brush nozzle 6 slidably connected to the top of the linear motor frame 5, a tube opening scraper 61 slidably connected inside the tube opening at the top of the brush nozzle 6, and a tube opening scraper 61. The top of the plate 61 has a through hole, and the bottom of the tube scraper 61 is fixedly connected to the inner scraper 62. The inner scraper 62 includes a main body 621 fixedly connected to the bottom of the tube scraper 61. The main body 621 is slidably connected to the top of the inner wall of the main body 621 by a spring. The left and right sides of the main body 621 are fixedly connected to the perforated plate body 622. The top of the perforated plate body 622 has a through hole, and the end of the perforated plate body 622 is inclined downward. The two sides of the inner wall of the main body 621 are rotatably connected to the cam rod 63. The cam rod 63 is located at the top of the inner scraper 62. The end of the cam rod 63 is equipped with a motor. The bottom of the main body 621 is fixedly connected to the lower connecting rod 64. The front and back of the lower connecting rod 64 are slidably connected to the side scraper 65 by a spring. The side scraper 65 is slidably connected to the inclined surface at the bottom of the inner wall of the brush nozzle 6.

[0028] A scraper 7 is provided on the back of the brush nozzle 6. The top of the scraper 7 is slidably connected to the top of the brush nozzle 6 via a hydraulic cylinder. The hydraulic cylinder is fixedly connected to the top of the brush nozzle 6. A pneumatic vibrator is integrated on the front of the brush nozzle 6. The top of the scraper 7 is rotatably connected to the hydraulic cylinder. A comprehensive testing component 8 is provided on the back of the frame 2. The comprehensive testing component 8 includes:

[0029] The lifting and stabilizing kit 81 includes a hydraulic base 811 located at the bottom of the conveyor frame 1. An electromagnetic pusher 812 is fixedly connected to the top of the hydraulic base 811. A contact plate 813 is slidably connected to the inner side of the outer surface of the electromagnetic pusher 812 via a spring. The outer surface of the contact plate 813 is covered with a rubber layer. There are two lifting and stabilizing kits 81, which are symmetrically distributed on the left and right sides of the conveyor frame 1.

[0030] The detection kit 82 includes a mounting bracket 821 fixedly connected to the top of the hydraulic base 811, an inclined nozzle 822 fixedly connected to the top of the mounting bracket 821, a contour sensor 823 fixedly connected to the top of the mounting bracket 821, and an industrial camera 824 fixedly connected to the top of the mounting bracket 821.

[0031] A printing detection component 9 is provided on the top of the brush nozzle 6. The printing detection component 9 includes an electromagnetic push rod 91 fixedly connected to the top of the brush nozzle 6. A rotating slide 92 is provided on the back of the electromagnetic push rod 91. The rotating slide 92 includes a rotating seat 921 fixedly connected to the back of the electromagnetic push rod 91. A slide cylinder 922 is fixedly connected to the bottom of the rotating seat 921. A sliding rotating rod 923 is slidably connected to the bottom of the slide cylinder 922 by a spring. The bottom of the sliding rotating rod 923 is fixedly connected to the top of the scraper plate 7.

[0032] In use, adjust the position of the residual material interception plate 31, place the electrolyte plate on top of the negative pressure seat 42, then connect the one-way valve of the plate body 41 to the air extraction device to extract air, and use negative pressure to adsorb the electrolyte plate on top of the negative pressure seat 42. Then, place the negative pressure mounting plate 4 on top of the conveyor frame 1. When the negative pressure mounting plate 4 reaches the bottom of the brush nozzle 6, the brush nozzle 6 slides back and forth under the drive of the linear motor frame 5, coating the top of the screen plate 3. During this process, the pneumatic vibrator works to generate vibration, promoting the flow of coating paint. During this process, the motor drives the cam rod 63 to rotate. The rotation of the cam rod 63 periodically pushes the inner scraper 62 to slide up and down. The inner scraper 62 drives the tube scraper 61 and the lower connecting rod 64 to slide up and down, reducing paint adhesion and clogging, and promoting paint dispersion. While the lower connecting rod 64 slides up and down, it drives the side scraper 65 to slide up and down. During the downward movement, under the compression of the spring, the side scraper 65 makes closer contact with the inside of the brush nozzle 6, scraping off the paint adhering to the inner wall of the brush nozzle 6.

[0033] The coating is screened by the screen plate 3 and covered on the top of the electrolyte plate to form an electrode. After the coating is completed, the hydraulic cylinder pushes the scraper 7 downward, and at the same time, the linear motor frame 5 drives the brush nozzle 6 to slide in the opposite direction, scraping the coating material in the opposite direction so that the coating material covers the surface of the electrolyte plate. During this process, the monitoring lens 93 judges the accuracy of the coating position by monitoring and identifying the images of the electrolyte plate and the screen plate 3 on the top of the negative pressure mounting plate 4, and controls the electromagnetic push rod 91 to drive the rotating carriage 92 to rotate to adjust the angle of the scraper 7.

[0034] After coating, the negative pressure mounting plate 4 rotates down the conveyor frame 1 to the bottom of the integrated testing assembly 8. When the negative pressure mounting plate 4 leaves the bottom of the screen plate 3, the excess material interception plate 31 intercepts the excess coating material from the surface of the electrolyte plate. As the negative pressure mounting plate 4 passes by, the tilting nozzle 822 cleans away the impurities remaining on the surface of the electrolyte plate by air jetting. Then, the negative pressure mounting plate 4 is clamped by the contact plate 813 and is lifted by the hydraulic base 811 to detach from the contact with the conveyor frame 1. During this process, the contour sensor 823 scans the top of the electrolyte plate and transmits the scanning data back to the electrical control cabinet 10. Then, the negative pressure mounting plate 4 is lowered by the lifting and stabilizing kit 81. The industrial camera 824 scans and identifies the image on the top of the electrode plate to determine the position of the printed electrode.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
