Description

Technical Field

[0001] The utility model belongs to the field of battery production equipment, and particularly relates to a battery capping colored glue device. Background Art

[0002] Before using a battery, a gel is often applied to the battery cap to complete the capping process. In existing capping technologies, it is difficult to effectively control the flow of the gel during each application process, causing the gel to drip onto other parts of the battery, making the capping process difficult and reducing production efficiency. Furthermore, the slow dispensing speed of the gel in existing technologies is also a major factor in the low production efficiency.

[0003] Application publication number CN104907226A discloses a battery cap dispensing device, comprising a workbench, a colloid supply barrel, and a dispensing system. The invention features automatic cleaning, an automatic alarm for low colloid levels, and a heat preservation function, solving the problem of colloid blockage in the dispensing barrel. It also reminds workers to add colloid to the dispensing barrel in a timely manner, and the heat preservation function prevents colloid from condensing inside the pipe. Although the invention with application publication number CN104907226A solves the aforementioned problems, it still has the following disadvantages: (1) it cannot control the dispensing of glue, which causes residual glue to drip, requiring manual wiping and reducing production efficiency; and (2) it cannot dispense glue quickly. Summary of the Invention

[0004] The utility model solves the problem that the battery cannot quickly discharge glue and cannot effectively stop the downward flow of glue during the sealing process. A battery capping colored glue device is provided. By arranging a glue gun on the capping colored glue device, the glue can be quickly discharged and the discharge of glue can be effectively stopped during the sealing process.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A battery capping device with colored glue includes a glue gun positioned above the battery. The glue gun is connected to a first air cylinder, which drives the glue gun up and down. The glue gun's glue filling port is connected to a second air cylinder and a colored glue barrel. The first cylinder drives the glue gun up and down, allowing the glue gun to reach above the battery for glue application and capping. The second cylinder provides power for the glue gun. A vent is provided above the colored glue barrel to facilitate the flow of glue from the barrel into the glue gun.

[0007] The glue gun includes a glue gun housing and a glue gun nozzle arranged below the glue gun housing. The glue gun housing and the glue gun nozzle can be connected by threads, so as to facilitate the disassembly, cleaning or maintenance of various internal components of the glue gun.

[0008] A colloid channel is provided in the glue gun housing, and a sealing plate is slidably provided at the lower part of the glue gun housing. A connecting rod is passed through the sealing plate, and the upper part of the connecting rod is connected to the second cylinder. The bottom of the connecting rod is connected to a sealing ball. The sealing ball is located below the sealing plate. The outer diameter of the sealing ball is larger than the aperture of the sealing plate for passing the connecting rod, so that the sealing ball can play a sealing effect when it contacts the sealing plate.

[0009] Preferably, two groups of glue guns are symmetrically arranged with the first cylinder as the center, and the two groups of glue guns are respectively connected to colored glue barrels filled with two different colored glues, so that the colloids used for sealing are different in color, so as to distinguish the positive and negative poles of the battery.

[0010] Preferably, a sealing ring is fixedly provided within the glue gun housing. The sealing ring is located above the sealing plate. A push rod hole is formed in the middle of the sealing ring, through which the connecting rod passes. The connecting rod comprises an upper power rod, a middle push rod, and a lower connecting rod. The diameter of the push rod matches the diameter of the push rod hole, the diameter of the power rod is smaller than the diameter of the push rod, and the diameter of the connecting rod is smaller than the diameter of the push rod. The sealing ring can divide the interior of the glue gun into upper and lower parts. When the push rod located in the middle of the connecting rod passes through the sealing ring, the hole in the center of the sealing ring is blocked by the push rod, thereby increasing the pressure of the push rod on the colloid below. At this time, the connecting rod drives the sealing ball to move downward, and the colloid flows downward through the sealing plate and out of the glue gun nozzle.

[0011] Preferably, a sealing ring groove is provided on the inner wall of the glue gun housing, and the sealing ring is fixed in the sealing ring groove.

[0012] Preferably, an annular plate is provided at the lower inner part of the glue gun housing, the annular plate is located below the sealing plate and the two are connected by a first spring, the middle part of the annular plate is a glue hole, a guide rod push piece is fixed on the connecting rod, a guide rod is provided above the sealing plate, the guide rod is passed through the sealing ring, one end of the guide rod is fixedly connected to the sealing plate, and the other end is fixed to the guide rod push piece.

[0013] Preferably, the guide rod is covered with a second spring, one end of which is fixed to the guide rod push piece and the other end is fixed to the sealing ring. After the glue application is completed, the first and second springs rebound to reset the connecting rod and the connected sealing ball, sealing plate, and guide rod. After reset, the sealing ball contacts the sealing plate, and the glue stops flowing downward.

[0014] Preferably, the inner wall of the glue gun nozzle is not flush with the inner wall of the glue gun housing and protrudes inward, and the annular plate is arranged above the inner wall of the glue gun nozzle, which facilitates the removal of the annular plate and its connecting device from the glue gun for cleaning or maintenance.

[0015] Through the above technical solution, the beneficial effects of the utility model are:

[0016] 1. The utility model realizes the work of sealing the battery cap with colored glue by arranging a glue gun and a colored glue barrel above the battery. A connecting rod, a sealing plate and a sealing ball are arranged in the glue gun. After the gluing work, the connecting rod is reset upward, thereby driving the sealing ball at the bottom of the connecting rod to contact the upper sealing plate, achieving the effect of sealing the colloid channel and effectively stopping the colloid from flowing downward.

[0017] 2. The utility model provides a connecting rod and a sealing ring inside the glue gun. When the glue is applied, the connecting rod inside the glue gun moves downward. When the push rod in the middle of the connecting rod passes through the sealing ring, the hole in the center of the sealing ring is blocked by the push rod, so that the push rod increases the pressure on the colloid below, and the colloid flows out quickly through the nozzle of the glue gun, thereby achieving the effect of rapid glue discharge.

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1 to 3 As shown, this embodiment provides a battery capping colored glue device, including two glue guns 1 located above the battery 17, the two glue guns 1 are fixed on the base 10, the base 10 is fixedly connected to the first cylinder 9 by bolts, and the glue guns 1 are symmetrically arranged with the first cylinder 9 as the center. Different colors of glue are respectively input into the two glue guns 1, so that the positive and negative poles of the battery are marked with different colors when capping.

[0024] In this embodiment, if Figure 1As shown, the first cylinder 9 is connected to the gas tank 8 through the first air pipe 11, and the first cylinder 9 drives the card seat 10 and the glue gun 1 to move up and down. The glue filling port of the glue gun 1 is connected to the second cylinder 12 and the color glue barrel 14. A sealed chamber 141 is set above the glue gun 1. The sealed chamber 141 is connected to the color glue barrel 14 through the glue pipe 15. A vent 142 is set above the color glue barrel 14. The color glue barrel 14 is provided with two groups corresponding to the glue gun 1, and two different colors of color glue are respectively loaded. The vent 142 can keep the color glue barrel 14 The internal pressure is atmospheric pressure. When the glue gun 1 completes the gluing work, the pressure inside the glue gun 1 is lower than the pressure inside the colored glue barrel 14. At this time, due to the simultaneous action of gravity and pressure, the colored colloid is transported from the colored glue barrel 14 to the sealed chamber 141 located below the colored glue barrel through the glue pipe 15, and then flows from the sealed chamber 141 to the glue gun 1 below. The second cylinder 12 is connected to the gas tank 8 through the second gas pipe 13. The gas tank 8 provides gas to the first cylinder 9 and the second cylinder 12. The colored glue barrel 14 and the gas tank 8 are fixed on the base 16.

[0025] In this embodiment, if Figure 2 As shown, the glue gun 1 includes a glue gun housing 5 and a glue gun nozzle 6 arranged below the glue gun housing 5. The glue gun housing 5 and the glue gun nozzle 6 are threadedly connected, so as to facilitate the disassembly, cleaning or maintenance of the internal components of the glue gun 1.

[0026] In this embodiment, if Figure 3 As shown, a sealing ring 21 is fixedly provided in the glue gun housing 5. The sealing ring 21 is located above the sealing plate 32. A sealing ring groove 213 is provided on the inner wall of the glue gun housing 5. The sealing ring 21 is fixed in the sealing ring groove 213. The middle part of the sealing ring 21 is a push rod hole 211, and a guide rod hole 212 is also provided on the sealing ring 21.

[0027] The lower part of the glue gun housing 5 is slidingly provided with a sealing plate 32, and a guide hole 321 is provided in the middle of the sealing plate 32. A connecting rod 2 is passed through the guide hole 321, and the connecting rod 2 includes an upper power rod 23, a middle push rod 22 and a lower connecting rod 31. The push rod 22 is threadedly connected to the power rod 23. In order to accommodate more colloid in the upper part of the glue gun 1, the diameter of the power rod 23 is set to be smaller than the diameter of the push rod 22. The upper part of the power rod 23 is connected to the piston rod of the second cylinder 12, and the downward movement of the piston rod of the second cylinder 12 drives the power rod 23 to move downward; the diameter of the push rod 22 is adapted to the push rod hole 211, so that when the push rod 22 passes through the push rod hole 211, the pressure in the glue gun below the sealing ring is increased to achieve rapid glue discharge; the bottom of the push rod 22 is threadedly connected to the connecting rod 31, and the diameter of the connecting rod 31 is smaller than the diameter of the push rod 22, so that when the connecting rod 2 is reset upward to Figure 2 In the initial position, the colloid can flow downward from the push rod hole 211 .

[0028] The connecting rod 31 passes through the guide hole 321 on the sealing plate 32. In order to allow the colloid to pass through the sealing plate 32 and flow downward, the diameter of the connecting rod 31 is set to be smaller than the diameter of the guide hole 321. The bottom of the connecting rod 31 is connected to a sealing ball 3. The sealing ball 3 is located below the sealing plate 32. In order to achieve the best sealing effect of the sealing ball 3, the diameter of the sealing ball 3 is set to be larger than the diameter of the guide hole 321. The colloid channel refers to the Figure 2 When the glue is applied, the connecting rod 31 in the guide hole 321 moves downward. At this time, the sealing ball 3 no longer seals the guide hole 321, and the glue continues to flow downward through the guide hole 321.

[0029] In this embodiment, if Figure 2 As shown, an annular plate 41 is provided in the lower part of the glue gun housing 5, and the annular plate 41 is located below the sealing plate 32 and the two are connected by a first spring 322. The middle part of the annular plate 41 is a glue hole, and a guide rod push piece 43 is fixed on the connecting rod 2. The guide rod push piece 43 moves up and down with the connecting rod 2. A guide rod 42 is provided above the sealing plate 32, and the guide rod 42 is inserted into the guide rod hole 212. One end of the guide rod 42 is fixedly connected to the sealing plate 32 and the other end is fixed to the guide rod push piece 43. The guide rod 42 is covered with a second spring 4 21, one end of the second spring 421 is fixed to the guide rod push piece 43, and the other end is fixed to the sealing ring 21. The sealing plate 32, the connecting rod 2 and the sealing ball 3 can be reset by the spring when the glue is applied. The spring coefficient of the first spring 322 is set to be smaller than the spring coefficient of the second spring 421, so that the reset speed of the first spring 322 is smaller than the reset speed of the second spring 421. When the second spring 421 completes its reset, the sealing ball 3 and the sealing plate 32 are in contact, the guide hole 321 is sealed, and the colloid stops flowing downward. Finally, the first spring is reset to Figure 2 The colloid flows downward through the push rod hole 211 to the top of the sealing plate 32 again, preparing for the next capping and gluing work.

[0030] The wall thickness of the upper portion of the glue gun nozzle 6 is greater than the wall thickness of the glue gun housing 5 . The annular plate 41 is disposed above the inner wall of the glue gun nozzle 6 , thereby making it easy to disassemble, clean, or maintain the annular plate 41 .

[0031] The specific working mode of the utility model is:

[0032] When the battery 17 is transported to the bottom of the glue gun 1, the first cylinder 9 drives the two glue guns 1 to move downward to the working position. In the initial position, the push rod 22 is located above the sealing ring 21, and the colloid flows downward to the top of the sealing plate 32 through the push rod hole 211. Then the second cylinder 12 drives the connecting rod 2 to move downward. As the connecting rod 2 moves downward to the sealing ring 21, the push rod 22 in the middle of the connecting rod 2 passes through the push rod hole 211 in the center of the sealing ring 21. The pressure below the sealing ring 21 gradually increases, and the connecting rod 2 continues to move downward. At this time, the sealing ball 3 no longer seals the guide hole 3. 21, the colloid continues to flow downward through the guide hole 321, thereby accelerating the colloid to flow out from the glue gun nozzle 6, completing the gluing work; after the gluing work is completed, the reset speed of the first spring 322 is less than the reset speed of the second spring 421, so that when the second spring 421 is reset, the sealing ball 3 and the sealing plate 32 are in contact, the guide hole 321 is sealed, and the colloid stops flowing downward, sealing the colloid channel, and finally the first spring 322 is reset to the initial position, and the colloid flows downward through the push rod hole 211 again to the top of the sealing plate 32, preparing for the next capping and gluing work.

[0033] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
