Description

Technical Field

[0001] This invention belongs to the field of sealing treatment technology in mechanical manufacturing and maintenance, and specifically relates to an automated cylinder adhesive application tool and method. Background Technology

[0002] In traditional industrial production or maintenance processes, cylinder sealing typically relies on manual operation, which is not only inefficient but also makes it difficult to guarantee the uniformity and quality of adhesive application. With the development of automation technology, various automated adhesive application equipment has emerged on the market. However, these devices are often designed for specific application scenarios, and for complex-shaped components like cylinders, existing solutions may not be flexible enough or costly. Therefore, developing an automated tool that can adapt to cylinders of different heights and shapes while ensuring both adhesive application quality and efficiency has become an industry requirement. Summary of the Invention

[0003] To address the technical problems existing in the prior art, the purpose of this invention is to provide an automated cylinder adhesive application tool. This invention aims to improve the efficiency of adhesive application operations, reduce manual intervention, and ensure the consistency and reliability of the adhesive application process. Furthermore, the tool should also possess a certain degree of flexibility to adapt to cylinders of different sizes and heights.

[0004] Another objective of this invention is to provide an automated method for applying adhesive to cylinders.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated cylinder gluing tool includes a main controller, a power module, an AGV (Automated Guided Vehicle), and a gluing adjustment module, a gluing observation module, and a gluing module arranged sequentially from bottom to top on the AGV. The gluing module includes a material trough and a bracket disposed in the material trough. A feeding electric roller, a smoothing electric roller, and a scraping roller are arranged sequentially from front to back on the bracket, with the smoothing electric roller and the scraping roller in close contact. The AGV, the gluing adjustment module, the observation module, and the gluing module are electrically connected to the main controller, and the main controller controls the actions of the AGV, the gluing adjustment module, and the gluing module.

[0007] Furthermore, an adjustment handle is provided on the side of the bracket to adjust the position of the smoothing roller so that the scraper roller and the smoothing roller are in close contact.

[0008] Furthermore, the upper surface of both the feeding roller and the smoothing roller is higher than the edge of the material trough.

[0009] Furthermore, the upper surface of the smoothing roller is slightly lower than the upper surface of the feeding roller.

[0010] Furthermore, the upper surface of the scraper roller is at a lower horizontal level than the upper surface of the smoothing roller.

[0011] Furthermore, the feeding electric roller and the smoothing electric roller rotate relative to each other during operation, with the feeding electric roller rotating from front to back and the smoothing electric roller rotating from back to front.

[0012] Furthermore, the power module includes a first power supply, a second power supply, and a third power supply respectively disposed inside the feeding electric roller and the smoothing electric roller, and disposed on the AGV trolley.

[0013] Furthermore, the AGV includes an AGV body, an obstacle avoidance photocell located in front of the AGV body, and a start button and an emergency stop switch located on the AGV body.

[0014] Furthermore, the adhesive application adjustment module includes a lifting mechanism and an adhesive application control mechanism; the adhesive application control mechanism includes a support plate mounted on the lifting mechanism, an optical fiber signal transmitter, an optical fiber signal receiver, and an adjustment component mounted on one side of the support plate; the other side of the support plate is connected to the lifting mechanism and forms a certain angle with the upper surface of the lifting mechanism; the optical fiber signal transmitter and the optical fiber signal receiver are distributed on both sides of the adjustment component; the optical fiber signal transmitter and the optical fiber signal receiver are electrically connected to the lifting mechanism, and control the movement of the lifting mechanism through the receiving status of the optical fiber signal.

[0015] Furthermore, the reception status of the optical fiber signal includes two states: on and off.

[0016] Furthermore, the lifting mechanism is a scissor lift platform.

[0017] Furthermore, the support plate is made of stainless steel.

[0018] Furthermore, the optical fiber signal transmitting device includes a first transmitting device and a second transmitting device, and the optical fiber signal receiving device is correspondingly provided with a first receiving device and a second receiving device, thereby obtaining a first optical fiber signal and a second optical fiber signal, wherein the horizontal height of the second optical fiber signal is lower than that of the first optical fiber signal.

[0019] Furthermore, the optical fiber signal transmitting device and the optical fiber signal receiving device are provided with a long slot; the first transmitting device and the first receiving device are disposed in the long slot, so that the horizontal height of the first optical fiber signal can be adjusted.

[0020] Furthermore, the lower surface of the adjusting member is at a height higher than the horizontal height of the first optical fiber signal, and in the working state, the adjusting member is at a height that only cuts off the first optical fiber signal.

[0021] Furthermore, one side of the support plate is placed in a fixed frame on the lifting mechanism and on a protrusion in front of the fixed frame, so that the support plate forms a certain angle with the upper surface of the lifting mechanism.

[0022] Furthermore, a support frame is provided on the support plate, and the support frame is connected to the glue application module.

[0023] Furthermore, the adhesive application observation module includes a lighting device and an image recognition device mounted on the lifting mechanism; the lighting devices are distributed at the four corners of the lifting mechanism; and the image recognition devices are distributed at the front and rear of the adhesive application module.

[0024] An automated cylinder adhesive application method, using the aforementioned automated cylinder adhesive application tool, includes the following steps:

[0025] (1) After lifting the cylinder surface of the low-pressure cylinder to a certain height, pour the liquid into the material trough. The amount of liquid poured in should meet the following requirements: the liquid should be in contact with the feeding electric roller, but not in contact with the smoothing electric roller and the scraping roller.

[0026] (2) Press the start button of the cylinder automatic glue applicator, and drive the automatic glue applicator to the position below the glue applicator on the cylinder surface through the main controller. Press the emergency stop switch to stop the cylinder automatic glue applicator from moving forward.

[0027] (3) Start the feeding electric roller and the smoothing electric roller through the main controller;

[0028] (4) Start the lifting mechanism through the main controller. The lifting mechanism rises. After the feeding electric roller carrying the liquid contacts the cylinder surface, the feeding electric roller is gradually subjected to pressure during the rising process, causing the support plate to deflect. The support plate drives the adjustment component to move down. When the adjustment component cuts off the first optical fiber signal, the lifting mechanism stops rising.

[0029] (5) Determine whether the thickness of the adhesive coating is appropriate by the image transmitted by the image recognition device; if the thickness needs to be reduced, adjust the horizontal height of the adjusting component or the first optical fiber signal until the first optical fiber signal is not cut off by the adjusting component, and raise the lifting mechanism until the adjusting component cuts off the first optical fiber signal; if the thickness needs to be increased, adjust the adjusting component downwards until the first optical fiber signal and the second optical fiber signal are cut off simultaneously, and lower the lifting mechanism until the adjusting component only cuts off the first optical fiber signal.

[0030] (6) The main controller controls the cylinder automatic glue application tool to complete the glue application along the trajectory of the cylinder surface.

[0031] Furthermore, during the continued upward movement described in step (4), the feeding roller is subjected to pressure, and the horizontal height of the upper surface of the smoothing roller is infinitely close to that of the upper surface of the feeding roller.

[0032] Furthermore, the lifting action of the lifting mechanism in step (4) is controlled by the receiving status of the optical fiber signal. When the first optical fiber signal is not cut off, the lifting mechanism continues to rise; when the first optical fiber signal is cut off, the lifting mechanism stops; when both the first and second optical fiber signals are cut off, the lifting mechanism descends until only the first optical fiber signal is cut off.

[0033] The implementation of this invention has the following beneficial effects:

[0034] (1) Improve work efficiency: Automated glue application tools greatly reduce the time of manual operation and improve the overall work efficiency.

[0035] (2) Ensure the quality of adhesive application: The coordinated operation of the feeding roller, the smoothing roller and the scraping roller ensures the uniform application of adhesive, thereby improving the quality and consistency of adhesive application.

[0036] (3) Reduce labor intensity: Automated tools replace the traditional manual glue application method, which reduces the labor intensity of workers and reduces the risk of work-related injuries.

[0037] (4) High flexibility: The design of the scissor lift platform allows the tool to adapt to cylinders of different heights, expanding its application range. Attached Figure Description

[0048] Example 1

[0049] like Figures 1-4 As shown, an automated cylinder gluing tool includes a main controller, a power module, an AGV (Automated Guided Vehicle), and a gluing adjustment module, a gluing observation module, and a gluing module arranged sequentially from bottom to top on the AGV. The gluing module includes a material trough 1 and a bracket 2 disposed in the material trough 1.

[0050] The bracket 2 is provided with an adjustment handle 6 on its side, which is used to adjust the position of the smoothing roller 4 so that the scraper roller 5 and the smoothing roller 4 are in close contact.

[0051] The upper surface of both the feeding roller 3 and the smoothing roller 4 is higher than the edge of the material trough 1.

[0052] The upper surface of the smoothing roller 4 is slightly lower than the upper surface of the feeding roller 3.

[0055] The power module includes a first power supply, a second power supply, and a third power supply 7, which are respectively installed inside the feeding electric roller and the smoothing electric roller.

[0056] The AGV includes an AGV body 8, an obstacle avoidance photocell 9 located in front of the AGV body 8, a start button 10 and an emergency stop switch 11 located on the AGV body 8.

[0057] The adhesive application adjustment module includes a lifting mechanism 12 and an adhesive application control mechanism. The adhesive application control mechanism includes a support plate 13 mounted on the lifting mechanism 12, an optical fiber signal transmitter 14, an optical fiber signal receiver 15, and an adjustment component 16 mounted on one side of the support plate 13. The other side of the support plate 13 is connected to the lifting mechanism 12 and forms a certain angle with the upper surface of the lifting mechanism 12. The optical fiber signal transmitter 14 and the optical fiber signal receiver 15 are distributed on both sides of the adjustment component 16. The optical fiber signal transmitter 14 and the optical fiber signal receiver 15 are electrically connected to the lifting mechanism 16 and control the movement of the lifting mechanism 12 through the reception status of the optical fiber signal.

[0058] The optical fiber signal reception status includes two states: on and off.

[0059] The lifting mechanism 12 is a scissor lift platform.

[0060] The support plate 13 is made of stainless steel.

[0061] The optical fiber signal transmitting device 14 includes a first transmitting device 1401 and a second transmitting device 1402. The optical fiber signal receiving device 15 is correspondingly provided with a first receiving device 1501 and a second receiving device 1502, thereby obtaining a first optical fiber signal and a second optical fiber signal, wherein the horizontal height of the second optical fiber signal is lower than that of the first optical fiber signal.

[0062] The optical fiber signal transmitting device 14 and the optical fiber signal receiving device 15 are provided with a long slot 1403; the first transmitting device 1401 and the first receiving device 1501 are provided in the long slot 1403 so that the horizontal height of the first optical fiber signal can be adjusted.

[0063] The lower surface of the adjusting member 16 is at a height higher than the horizontal height of the first optical fiber signal. In the working state, the adjusting member 16 is at a height that only cuts off the first optical fiber signal.

[0064] One side of the support plate 13 is placed in the fixed frame 17 set on the lifting mechanism 12, and is placed on the protrusion 18 set in front of the fixed frame 17, so that the support plate 13 forms a certain angle with the upper surface of the lifting mechanism 12.

[0065] A support frame 19 is provided on the support plate 13, and the support frame 19 is connected to the glue application module.

[0066] The adhesive application observation module includes a lighting device 20 and an image recognition device 21 mounted on the lifting mechanism 12; the lighting device 20 is distributed at the four corners of the lifting mechanism 12; the image recognition device 21 is distributed at the front and rear of the adhesive application module.

[0067] An automated cylinder adhesive application method, using the automated cylinder adhesive application tool of the present invention, includes the following steps:

[0068] (1) After lifting the cylinder surface of the low-pressure cylinder to a certain height, pour the liquid into the material trough 1. The amount of liquid poured in should meet the following requirements: the liquid is in contact with the feeding electric roller 3, but not in contact with the smoothing electric roller 4 and the scraping roller 5.

[0069] (2) Press the start button 10 of the cylinder automatic glue applicator, and drive the automatic glue applicator to the position below the glue applicator on the cylinder surface through the main controller. Press the emergency stop switch 11 to stop the cylinder automatic glue applicator from moving forward.

[0070] (3) Start the feeding electric roller 3 and the smoothing electric roller 4 through the main controller;

[0071] (4) Start the lifting mechanism 12 through the main controller. The lifting mechanism 12 rises. After the feeding electric roller 3 carrying the liquid material contacts the cylinder surface, the feeding electric roller 3 is gradually subjected to pressure during the rising process, causing the support plate 13 to deflect. The support plate 13 drives the adjusting component 16 to move down. When the adjusting component 16 cuts off the first optical fiber signal, the lifting mechanism stops rising.

[0072] (5) Determine whether the thickness of the adhesive coating is appropriate by using the image transmitted by the image recognition device 21; if the thickness needs to be reduced, adjust the horizontal height of the adjusting member 16 or the first optical fiber signal until the first optical fiber signal is not cut off by the adjusting member 16, and raise the lifting mechanism 12 until the adjusting member 16 cuts off the first optical fiber signal; if the thickness needs to be increased, adjust the adjusting member 16 downward until the first optical fiber signal and the second optical fiber signal are cut off simultaneously, and lower the lifting mechanism 12 until the adjusting member 16 only cuts off the first optical fiber signal.

[0073] (6) The main controller controls the cylinder automatic glue application tool to complete the glue application along the trajectory of the cylinder surface.

[0074] During the continued upward movement described in step (4), the feeding roller 3 is subjected to pressure, and the horizontal height of the upper surface of the smoothing roller 4 is infinitely close to that of the upper surface of the feeding roller 3.

[0075] The lifting action of the lifting mechanism 12 in step (4) is controlled by the receiving status of the optical fiber signal. When the first optical fiber signal is not cut off, the lifting mechanism 12 continues to rise; when the first optical fiber signal is cut off, the lifting mechanism 12 stops; when both the first and second optical fiber signals are cut off, the lifting mechanism 12 descends until only the first optical fiber signal is cut off.

[0076] The lifting mechanism 12 in step (4) is a scissor lift with a lifting range of 285mm to 590mm.

[0077] During the glue application in step (6), the working states of the feeding roller 3, the smoothing roller 4, and the scraping roller 5 are as follows: Figure 5 As shown, A represents the movement direction of the feeding roller 3, B represents the movement direction of the smoothing roller 4, and C represents the forward direction of the automated cylinder gluing tool. The feeding roller 3 is responsible for carrying the adhesive from the material trough 1 onto the cylinder surface. The smoothing roller 4 is responsible for smoothing the adhesive adhering to the cylinder surface. The scraper roller 5 is mainly responsible for removing the adhesive from the smoothing roller 4, ensuring the smoothness of the roller surface. If the adhesive on the smoothing roller 4 cannot be removed relatively cleanly, it can be finely adjusted using the adjustment handle 6. After loosening the screw, turn the handle to ensure that the scraper roller 5 and the smoothing roller 4 are tightly attached, and then tighten the screw using the provided tool.

[0078] When the automated cylinder adhesive applicator encounters a raised or recessed surface during operation, it can automatically adjust its coating thickness through a working mechanism of pressure-adjustment-fiber optic signal-lifting mechanism. For example, when encountering a raised surface during operation, the feeding roller 3 and the smoothing roller 4 are subjected to greater pressure, causing the support plate 13 to deflect more violently. This drives the adjustment component 16 to move further downward, changing the process from cutting off only the first fiber optic signal to simultaneously cutting off both the first and second fiber optic signals. The lifting mechanism 12 then moves downward until only the first fiber optic signal is cut off.

[0079] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
