Description

Technical Field

[0001] The invention relates to the technical field of pen sealing detection, in particular to a pen sealing detection device and method. Background Art

[0002] In a broad sense, a fountain pen is a commonly used writing instrument. It is a pen-type writing instrument that mainly uses metal as the pen body. The ink is held in the hollow pen tube, and writing is done through gravity and capillary action through the duckbill-style pen head. With the development of technology, more types of fountain pens have been developed, including pens with quickly replaceable ink cartridges. Compared with traditional fountain pens, this type of fountain pen can replenish ink more quickly. You only need to plug the ink cartridge into the back of the fountain pen, which effectively improves the convenience of using the fountain pen. The writing is smooth and elastic, quite fluent, and at the mouth of the pen cap Or the surface of the pen tip, there are obvious trademark brands and models. If it is divided into dip pens, tap pens and ink sac pens according to the water absorption method, attention should be paid to maintenance and cleaning when using. Poor sealing of the pen will not only affect the normal water flow of the pen, resulting in uneven writing, water interruption or uneven strokes, but also cause ink leakage in the pen, causing stains on the hands, pens, paper and tables, and troublesome cleaning. Therefore, the sealing of the water storage parts of the pen is an important parameter indicator. Therefore, after the water storage parts of the pen are assembled, a sealing test is required to ensure the quality of each pen.

[0003] During use, the existing pen sealing detection device is mostly placed in water and filled with gas of a certain pressure. The pen's sealing is judged by observing whether bubbles are generated in the water. However, the pen tested in this way is not easy to clean and water is easy to enter the inside. In addition, manual observation is inefficient. If multiple pens are tested at one time, the sealing of each pen cannot be quickly judged. In addition, it is not convenient to take out the tested pen, which further reduces the pen's detection efficiency and is not conducive to use. Therefore, we propose a pen sealing detection device.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing pen sealing detection devices on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect. Therefore, we propose a pen sealing detection device and method. Summary of the invention

If the front end of the pen is out If there is a leakage, gas will enter the sealing sleeve 2209, and the gas will continue to be filled. The gas in the sealing sleeve 2209 will push the sealing plate 2207, so that the sealing plate 2207 moves forward to squeeze the first spring 2208. At the same time, the sealing plate 2207 will drive the second contact block 2211 to move forward away from the first contact block 2210.

When the first contact block 2210 separates from the second contact block 2211, the detection light 2204 is in the on state. The sealing of the pen can be judged by observing the state of the detection light 2204, and then the pen with leakage can be taken out separately. S3. When the detection is completed, the first cylinder 2218 is controlled to operate to drive the movable sleeve 2203 to move backward for reset. The movable sleeve 2203 is removed from the surface of the pen. At the same time, the reset of the second spring 2213 will drive the push block 2212 to squeeze the pen, so that the front end of the pen is moved out of the sealing sleeve 2209, and the restriction of the movable sleeve 2203 and the sealing sleeve 2209 on the pen is released. Then the second cylinder 3002 is controlled to operate, which can drive one end of the support frame 3005 to move upward, and the other end of the support frame 3005 will drive one side of the unloading frame 3001 to tilt upward, so that the pen on the top of the placement shell 11 can be adjusted upward.

10. A method for using a pen sealing detection device, characterized in that: The following steps are involved: S1. Place the pens to be tested on a plurality of placement shells (11) in sequence, and then control the motor (2101) to drive the screw (2103) to rotate. The rotation of the screw (2103) drives the screw sleeve (2104) to move downward. The screw sleeve (2104) can drive the lifting plate (2102) and the pressing wheel (2108) to move downward through the cooperation of the lifting sleeve (2105), the lifting block (2106) and the lifting rod (2107). The pressing wheel (2108) gradually approaches the top of the pen until it is tightly attached to the top of the pen, so as to press and limit the pen to prevent it from being displaced. S2, then control the first cylinder (2218) to operate and drive the moving tube (2214) to move forward through the cooperation of the adjustment frame (2219) and the adjustment plate (2217), and the moving tube (2214) drives the moving sleeve (2203) to be sleeved on one end of the pen, and the moving sleeve (2203) continues to move to drive the other end of the pen to move forward, and the front end of the pen gradually enters the sealing sleeve (2209), and the pen continues to move to squeeze the push block (2212), and the device presses and fixes the pen through the cooperation of the moving sleeve (2203), and then the gas can be filled into the moving tube (2214) through the cooperation of the air inlet pipe (2216), and the gas enters the pen through the moving tube (2214) and the moving sleeve (2203). If the front end of the pen appears In case of air leakage, gas will enter the sealing sleeve (2209). As the gas is continuously filled, the gas in the sealing sleeve (2209) will push the sealing plate (2207), causing the sealing plate (2207) to move forward and squeeze the first spring (2208). At the same time, the sealing plate (2207) will drive the second contact block (2211) to move forward and away from the first contact block (2210). When the first contact block (2210) is in contact with the second contact block (2211), the detection light (2204) is in an off state. When the first contact block (2210) is separated from the second contact block (2211), the detection light (2204) is in an on state. The sealing property of the pen can be judged by observing the state of the detection light (2204), and the pen with leakage can be taken out separately. S3. After the detection is completed, the first air cylinder (2218) is controlled to operate to drive the movable sleeve (2203) to move backward for reset, and the movable sleeve (2203) is removed from the surface of the pen. At the same time, the reset of the second spring (2213) drives the push block (2212) to squeeze the pen, so that the front end of the pen moves out of the sealing sleeve (2209), and the restriction of the movable sleeve (2203) and the sealing sleeve (2209) on the pen is released. Then, the second air cylinder (3002) is controlled to operate to drive one end of the support frame (3005) to move upward, and the other end of the support frame (3005) drives one side of the discharge frame (3001) to tilt upward, so that the pen on the top of the placement shell (11) can be adjusted upward. After the pen is removed from the placement shell (11), it will roll downward on the surface of the discharge frame (3001) and finally fall into the receiving box (3003), completing the rapid discharge.
