[0038] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.

[0039] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0040] Reference Figures 1 to 5This utility model provides an empty roll gluing device that can accurately position the empty roll 8 before the electrode is wound up, and automatically apply glue to the empty roll 8, effectively improving the glue application quality of the empty roll 8 and the winding efficiency of the electrode. It includes a frame 1, a gluing module 3, a transverse component 5, a lifting component 4, and a glue supply component 6. The frame 1 is the base of the empty roll gluing device, used to install and support the various components. The frame 1 can be a gantry structure, a frame structure, etc., and is not limited to any particular type. Positioning brackets 2 are provided on both sides of the frame 1, symmetrically arranged to position and support both ends of the empty roll 8, ensuring the empty roll 8 is installed in place and thus guaranteeing the glue application quality. The lifting assembly 4 is connected to the frame 1 and is used to drive the glue application module 3 to move vertically closer to or further away from the empty roll 8. The traversing assembly 5 is mounted on the frame 1 and is used to drive the glue application module 3 to reciprocate along the axial direction of the empty roll 8 on the frame 1 to perform glue application on the empty roll 8. The glue application module 3 is used to perform glue application on the empty roll 8 and includes a control valve assembly 32 and a glue application head 31. The glue application head 31 has a glue application surface 311 adapted to the surface shape of the empty roll 8 so as to evenly apply the glue to the surface of the empty roll 8. The control valve assembly 32 is connected to the glue application head 31 and to the glue supply assembly 6. The control valve assembly 32 is used to control whether the glue application head 31 feeds glue. The glue supply assembly 6 is located on one side of the frame 1 and is used to supply glue to the glue application head 31. In this embodiment, the applicator head 31 can perform either applicator application or applicator scraping. When the control valve assembly 32 supplies adhesive to the applicator head 31, the lateral movement assembly 5 drives the applicator head 31 to apply the adhesive onto the empty roll 8. When the control valve assembly 32 does not supply adhesive to the applicator head 31, the lateral movement assembly 5 drives the applicator head 31 to perform applicator scraping. Specifically, a buffer spring (not shown in the figure) is provided inside the applicator head 31, allowing the applicator surface 311 to extend and retract. When the applicator head 31 contacts and presses against the surface of the empty roll 8, the buffer spring contracts. This configuration controls the amount of interference between the applicator surface 311 and the surface of the empty roll 8, maintaining a constant pressure between them, thus resulting in more uniform applicator scraping.

[0041] In addition, the empty roll coating device of this utility model also includes conventional structures such as an operation control unit, an electrical cabinet, and a three-color safety warning light. Its connection structure and working principle can be referred to the existing technology, and will not be described in detail here.

[0042] Reference Figure 2 and Figure 3The positioning bracket 2 has a V-shaped groove structure on the side that contacts the empty roll 8, and photoelectric positioning detection elements 23 are fixedly installed on opposite sides of the frame 1. The photoelectric positioning detection elements 23 are used to detect whether the empty roll 8 is installed in place. The positioning bracket 2 has a V-shaped groove structure, which can position both ends of the empty roll 8 to ensure that the empty roll 8 is installed in place for subsequent glue application. In use, the AGV transport trolley places the empty roll 8 on the positioning bracket 2. Due to the V-shaped groove structure of the positioning bracket 2, there is no need to manually adjust the empty roll 8 for positioning, which helps to improve work efficiency. The photoelectric positioning detection element 23 is electrically connected to the operation control unit. When the empty roll 8 is placed on the positioning bracket 2, the photoelectric positioning detection element 23 detects once and sends the detection signal to the control unit.

[0043] Because the AGV transport vehicle itself has low positioning accuracy, large angle error, or strong randomness, the empty drum 8 can be repositioned by setting a positioning bracket 2 and a photoelectric positioning detection component 23. This can effectively ensure the accuracy of the empty drum 8's position and thus ensure the accuracy of the glue application position.

[0044] Furthermore, a bracket support 11 is fixedly connected to the frame 1, and a positioning bracket 2 is installed on the bracket support 11. Specifically, the positioning bracket 2 includes a V-bracket 21 and a V-plate 22. The V-plate 22 is fixedly connected to the bracket support 11. Two oblong holes 221 are symmetrically opened on the V-plate 22. A fixing bolt 222 is connected in the oblong hole 221. The tail end of the fixing bolt 222 passes through the oblong hole 221 and is threaded to the V-bracket 21. The fixing bolt 222 can slide up and down along the oblong hole 221. An adjusting bolt 211 is threaded to the bottom of the V-bracket 21. The tail end of the adjusting bolt 211 extends into the oblong hole 221 and abuts against the fixing bolt 222.

[0045] Before placing the empty drum 8, the two adjusting bolts 211 on one side of the V-plate 22 can be rotated synchronously to control how much the tail end of the adjusting bolt 211 extends into the oblong hole 221, thereby causing the fixing bolt 222 to slide up and down in the oblong hole 221, and thus fine-tuning the vertical position of the V-support 21. The installation angle of the V-support 21 can also be fine-tuned by adjusting the two adjusting bolts 211 on one side of the V-plate 22, thus achieving fine-tuning of the vertical and horizontal installation position of the empty drum 8. Similarly, the adjusting bolts 211 on both sides of the V-plate 22 of the frame 1 can be adjusted as needed to ensure that the positioning bracket 2 positions and supports the empty drum 8 in the required position, effectively reducing the impact of the installation error of the positioning bracket 2 on the positioning of the empty drum 8.

[0046] Reference Figure 2 and Figure 4The adhesive application module 3 also includes a mounting plate 41. A control valve assembly 32 and an adhesive scraper head 31 are both mounted on the mounting plate 41. The mounting plate 41 is connected to the lifting assembly 4. The lifting assembly 4 drives the mounting plate 41 to move vertically, thereby causing the adhesive application module 3 to move vertically. In some embodiments, the lifting assembly 4 is a lifting linear motor module, and the lateral movement assembly 5 is a lateral movement linear motor module. A drag chain is provided on one side of both the lifting linear motor module and the lateral movement assembly 5. A lateral movement plate 51 is fixedly mounted on one side of the lifting linear motor module and is connected to the lateral movement linear motor module. The lateral movement linear motor module drives the lateral movement plate 51 to slide on the crossbeam 12, causing the lifting linear motor module to slide along the axial direction of the empty drum 8, thereby realizing the adhesive application action of the adhesive application module 3. The mounting plate 41 and the lateral movement plate 51 are driven by a linear motor module, which is well known and achievable by those skilled in the art and can be referred to in the prior art; therefore, it will not be described in detail in this embodiment.

[0047] Furthermore, in this embodiment, the frame 1 includes a crossbeam 12 and two side supports 13. The two side supports 13 are symmetrically erected at both ends of the crossbeam 12, and the transverse moving component 5 is fixedly mounted on the top of the crossbeam 12. A limiting guide rail 121 is fixedly mounted on the crossbeam 12, and the limiting guide rail 121 extends along the length direction of the crossbeam 12. A limiting slider (not shown in the figure) is fixedly mounted on one side of the lifting linear motor module, and the limiting slider is slidably connected to the limiting guide rail 121. The limiting slider cooperates with the limiting guide rail 121 to limit the sliding of the lifting component 4 along the length direction of the crossbeam 12, which can effectively ensure the stability of the sliding and thus ensure the uniformity of the glue application by the glue applicator 31.

[0048] Reference Figure 4The control valve assembly 32 includes an inlet valve 321, an outlet valve 323, and a storage valve 322. The storage valve 322 stores a small amount of adhesive for the application head 31 to perform one application. The inlet valve 321 is connected to the adhesive supply assembly 6, the storage valve 322 is connected to the inlet valve 321, and the outlet valve 323 is connected to the storage valve 322 and the application head 31. The inlet valve 321 and the outlet valve 323 can be controlled by solenoid valves. When preparing to apply adhesive, the inlet valve 321 is opened, and the adhesive supply system supplies adhesive, ensuring the storage valve 322 has sufficient adhesive. When applying adhesive, the inlet valve 321 is closed, and the outlet valve 323 is opened, allowing the adhesive to be delivered to the application head 31 for the application operation. During glue application, both the glue inlet valve 321 and the glue outlet valve 323 are closed, meaning the glue applicator head 31 does not output glue, allowing the existing glue on the surface of the empty roll 8 to be evenly applied. The glue supplied from the glue supply assembly 6 enters the glue storage valve 322 through the glue inlet valve 321, and then is delivered to the glue applicator head 31 via the glue outlet valve 323. To precisely control the amount of glue stored in the glue storage valve 322, a precision pressure regulating valve can be used to adjust the back pressure of the glue storage valve 322, thereby regulating the amount of glue stored.

[0049] In some embodiments, the adhesive application module 3 also includes heating and air supply devices such as a heating pack and a hot air knife mounted on the mounting plate 41. The heating pack heats the air and delivers it to the hot air knife. When the adhesive application head 31 performs the adhesive application action, the hot air knife blows hot air onto the empty roll 8 to dry the adhesive. The specific installation structure and implementation principle of the heating pack and hot air knife can be referred to the prior art, and will not be elaborated here.

[0050] Furthermore, refer to Figure 2 , Figure 3 and Figure 5 The frame 1 is also equipped with a scraper cleaning module 9, which includes a cleaning box 94, a cleaning cloth 91, an unwinding roller 92, and a take-up roller 93. The cleaning box 94 is fixedly mounted on the frame 1, specifically on the side support 13, and located below the scraper head 31. The cleaning cloth 91 is mounted on the cleaning box 94 and faces the scraper head 31. The unwinding roller 92 is located inside the cleaning box 94 and is used to unwind the clean cleaning cloth 91. The take-up roller 93 is located inside the cleaning box 94 and is used to take up the wiped cleaning cloth 91. The cleaning cloth 91 can wipe away any residual adhesive on the scraper head 31. When cleaning the coating head 31, the lifting assembly 4 is activated to drive the coating module 3 to descend until the coating head 31 contacts the cleaning cloth 91. Then, the take-up roller 93 and unwind roller 92 are activated to take up and unwind the cleaning cloth 91, so that the cleaning cloth 91 wipes the coating head 31. A guide roller is also provided inside the cleaning box 94, and the cleaning cloth 91 is wound around the guide roller.

[0051] Furthermore, the scraper cleaning module 9 also includes foam 95, which is disposed on the cleaning box 94 and located on one side of the cleaning cloth 91. The foam 95 has a moist sponge structure to keep the scraper head 31 moist. When the scraper head 31 is not scraping glue, the glue application module 3 is driven to move so that the scraper head 31 is placed on the foam 95 to reduce the possibility that the glue will solidify and affect the scraper head 31 and thus affect the scraping glue function.

[0052] Reference Figure 1 and Figure 4 The glue supply assembly 6 includes a glue storage tank 61 and a glue supply pipe 62. The glue supply pipe 62 connects the glue storage tank 61 and the glue application module 3, allowing the glue in the glue storage tank 61 to be transferred to the glue application module 3. A pressing assembly 63 is provided on the glue storage tank 61. The pressing assembly 63 includes a pressing motor and a pressing head. The pressing motor drives the pressing head to squeeze the glue in the glue storage tank 61 into the glue supply pipe 62 for delivery. In this embodiment, the glue supply pipe 62 is connected to both the glue storage tank 61 and the glue inlet valve 321 in the glue application module 3. Specifically, the glue supply pipe 62 can be connected and fixed to the glue inlet valve 321 using a conventional pipe connection structure such as a clamp.

[0053] The empty roll coating device of this utility model also includes a safety guardrail 7, which is set around the outer perimeter of the entire mechanism to provide safety protection for the entire workspace and improve the user's operational safety.

[0054] The working process of this utility model is as follows:

[0055] The AGV transport trolley transports the empty roll 8 to the front of the frame 1, and then places the empty roll 8 on the positioning bracket 2. At this time, the photoelectric positioning detector 23 detects the positioning signal of the empty roll 8 and sends a positioning signal to the operation control unit. After receiving the positioning signal, the operation control unit drives the lifting assembly 4 to lower the glue application module 3 to the end of the empty roll 8 and contact the surface of the empty roll 8. Then, the lateral movement assembly 5 drives the glue application module 3 to move laterally to apply glue until the glue application module 3 moves laterally to the other end of the empty roll 8. Then, the lateral movement assembly 5 pauses, the lifting assembly 4 drives the glue application module 3 to rise to the initial height, and then the lateral movement assembly 5 drives the glue application module 3 back to above the scraper cleaning module 9. The lifting assembly 4 drives the glue application module 3 to lower until it contacts the cleaning cloth 91. The unwinding roller 92 unwinds and the take-up roller 93 rewinds, so that the cleaning cloth 91 wipes the scraper head 31. Then, the scraper head 31 is driven to move onto the foam 95 to wait for the next glue application instruction.

[0056] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments.
