[0068] See also Figure 1-10 The present invention shows a lithium battery pole piece intelligent gluing machine, including a supporting frame 1, a control system, a pole piece conveying mechanism 2 and a battery tape conveying and correcting mechanism 3.

Of course, a plurality of pole piece driven rollers 25 are also provided on the first base 20 to assist the pole piece 26 to bypass the first glue pressing and heating assembly, the pole piece active roller device 23 and the pole piece buffer adjustment device 24 in sequence from the position of the pole piece detection unit 21 .

[0070] Specifically, the battery tape conveying and correcting mechanism 3 includes a second base 30, a tape detection unit 31, a second glue pressing mechanism 32, a tape active roller device 33 and a correcting sliding mechanism 34; the second base 30 is arranged opposite to the first base 20, but the second base 30 is not fixedly connected to the supporting frame 1, that is, it can be understood that the supporting frame 1 only supports the second base 30 but does not fix it. Among them, the tape detection unit 31 is fixedly mounted on the second base 30 to detect the position of the hot melt adhesive on the tape 36; the tape active roller device 33 is fixedly mounted on the second base 30 to drive the transmission of the tape 36; the second glue pressing mechanism 32 is fixedly mounted on the second base 30, and the second glue pressing mechanism 32 has the same structure as the first glue pressing mechanism 22 and the second glue pressing mechanism 32 is arranged opposite to the first glue pressing mechanism 22; further, the second glue pressing mechanism 32 includes a second pressing cylinder and a second glue pressing heating assembly, and the second pressing cylinder is connected to the second glue pressing heating assembly so that the second pressing cylinder The tightening cylinder can drive the second glue pressing and heating component to move closer to the first glue pressing and heating component; the correcting sliding mechanism 34 is fixed at the bottom of the second base 30, and is used to correct the movement of the second base 30; in addition, the tape active roller device 33 serves as a power source for driving the tape 36, driving the tape 36 from the position of the tape detection unit 31 to bypass the second glue pressing and heating component and the tape active roller device 33 in sequence, and when the second tightening cylinder drives the second glue pressing and heating component to move closer to the first glue pressing and heating component, the side of the tape 36 with hot melt adhesive attached can contact the surface of the pole piece 26. Of course, a number of tape driven rollers 35 are also provided on the second base 30, which are used to assist the tape 36 to bypass the second glue pressing and heating component and the tape active roller device 33 in sequence from the position of the tape detection unit 31.

[0071] During the simultaneous transmission of the pole piece 26 and the tape 36, the pole piece detection unit 21 detects the position of the pole piece 26 being glued, and the tape detection unit 31 detects the position of the hot melt adhesive on the tape 36. The correcting sliding mechanism 34 corrects the second base 30 according to the information fed back by the pole piece detection unit 21 and the tape detection unit 31, so that the position of the hot melt adhesive on the correcting tape 36 is aligned with the position of the pole piece 26 being glued; at the position of the first glue pressing heating component and the second glue pressing heating component, the first glue pressing heating component heats the pole piece 26, and the second glue pressing heating component heats the tape 36, and the hot melt adhesive attached to the tape 36 is heated and separated from it, so that the hot melt adhesive on the tape 36 is attached to the pole piece 26, thereby controlling the accuracy of the glue sticking of the pole piece 26, ensuring the stability of the product, and improving production efficiency. Of course, in order to facilitate the separation of the hot melt adhesive on the tape 36 from the tape 36, a blowing device 39 is also provided on the second base 30, and the blowing device 39 can blow air toward the position of the tape 36 at the second adhesive pressing and heating component. The hot melt adhesive on the tape 36 is heated by the second pressing and heating component, and then blows air toward it with the help of the blowing device 39, so as to facilitate the separation of the hot melt adhesive on the tape 36 from the tape 36. It should be noted that the blowing device 39 can be selected from the blowing device 39 in the prior art, as long as it can ensure that it can blow air toward the position of the tape 36 at the second adhesive pressing and heating component, and the blowing device 39 will not be specifically described here.

[0072] like Figure 4-6As shown, the first glue pressing and heating assembly includes a first support plate 220, a first mounting frame 221, a first roller 2210, a first electric heating rod 225 and a first thermocouple temperature sensor 226. The first support plate 220 is fixed on the first base 20, and the first pressing cylinder 222 is arranged on the first support plate 220 to drive the first glue pressing and heating assembly; of course, a guide device 223 is also arranged on the first support plate 220 to guide the first glue pressing and heating assembly when the first pressing cylinder 222 drives the first glue pressing and heating assembly to move. The guide device 223 can use a telescopic rod of the prior art, which will not be described in detail here. The first mounting frame 221 is connected to the movable end of the first pressing cylinder 222 and is vertically arranged with the first base 20; the first roller 2210 is arranged on the first mounting frame 221, and the first roller 2210 is arranged along the height direction of the first mounting frame; the first electric heating rod 225 and the first thermocouple temperature sensor 226 are both installed in the first roller 2210, and the heat generated by the first electric heating rod 225 can heat the outer wall of the first roller 2210 through heat conduction; the first thermocouple temperature sensor 226 is used to sense the temperature of the first electric heating rod 225, and can feed back the temperature information of the first electric heating rod 225 detected to the control system, so as to adjust and control the temperature of the first electric heating rod 225 within a set range. In addition, since the first glue pressing mechanism 22 and the second glue pressing mechanism 32 have the same structure, it can be understood that the structure of the second glue pressing heating component is also the same as that of the first glue pressing heating component, which will not be elaborated in detail here. It should be noted that the operating temperature range of the first electric heating rod 225 is set to 115-125°, and the optimal temperature setting is 120°; similarly, the operating temperature range of the electric heating rod in the second glue pressing heating assembly is also 115-125°, and the optimal temperature setting is 120°.

[0073] As a preferred embodiment, a first rotating shaft 22100 is provided at the upper end of the first roller 2210, and the first rotating shaft 22100 is coaxially arranged with the first roller 2210, and an upper bearing cooperating with the first rotating shaft 22100 is provided at the upper end of the first mounting frame 221, that is, the upper end of the first mounting frame 221 is provided with an upper bearing cooperating with the first rotating shaft 22100 arranged at the upper end of the first roller 2210 to achieve connection; a second rotating shaft 22101 is provided at the lower end of the first roller 2210, and the second rotating shaft 22101 is coaxially arranged with the first roller 2210, and a lower bearing cooperating with the second rotating shaft 22101 is provided at the lower end of the first mounting frame 221, that is, the lower end of the first mounting frame 221 is provided with a lower bearing cooperating with the second rotating shaft 22101 arranged at the lower end of the first roller 2210 to achieve connection.

[0074] As a preferred embodiment, the first heating group further includes a through-hole slip ring 224, which is installed on the second rotating shaft 22101 and is located between the bottom of the first roller 2210 and the bottom of the first mounting frame 221. Since the first roller 2210 will passively rotate during the process of pulling the lithium battery pole piece 26 and the battery tape 36, that is, the lithium battery pole piece 26 and the battery tape 36 will drive the first roller 2210 to rotate, and the first electric heating rod 225 and the first thermocouple temperature sensor 226 are both installed inside the first roller 2210, the wires of the first electric heating rod 225 and the first thermocouple temperature sensor 226 will be entangled with the rotation of the first roller 2210. Therefore, the through-hole slip ring 224 is installed on the second rotating shaft 22101 to prevent the wires from being entangled.

[0075] It should be noted that the through-hole slip ring 224 is a general term for a series of conductive slip rings with a hole in the center, which is an electrical component responsible for connecting the rotating body and transmitting energy and signals; according to the transmission medium, the slip ring is divided into electric slip ring, fluid slip ring, smooth slip ring, which can also be generally referred to as "rotational connection" or "rotational connection". In addition, the slip ring is usually installed at the rotation center of the equipment, mainly composed of two parts: rotating and stationary. The rotating part is connected to the rotating structure of the equipment and rotates with it, which is called "rotor"; the stationary part is connected to the energy of the fixed structure of the equipment, which is called "stator". It can be understood that the through-hole slip ring 224 here is installed on the second rotating shaft 22101, its inner ring rotates with the second rotating shaft 22101, and its outer ring is fixed on the first mounting frame 221. The wires of the first electric heating rod 225 and the first thermocouple temperature sensor 226 pass through the bottom of the first roller 2210 and are connected to the input wire of the through-hole slip ring 224, so as to prevent the phenomenon of wire entanglement.

[0076] like Figure 7 As shown, the active roller 231 device of the pole piece 26 includes an active roller 231, a mounting door frame 230, an active roller driving device 232 and an active roller pressing device 233, wherein the mounting door frame 230 is fixed on the first base 20 and is perpendicular to the first base 20; the active roller 231 is installed in the mounting door frame 230 and is arranged along the height direction of the mounting door frame 230; the active roller driving device 232 is used to drive the active roller 231 to rotate, and the active roller driving device 232 uses a servo motor; the active roller pressing device 233 is arranged on one side of the active roller 231, and is used to press the pole piece 26 to fit the outer wall of the active roller 231, so that the active roller driving device 232 (servo motor) drives the active roller 231 to rotate, thereby driving the transmission of the pole piece 26.

[0077] Specifically, Figure 7As shown, the active roller clamping device 233 includes a pressing cylinder 2332, a pressing cylinder mounting plate 2330 and a pressing cylinder clamping cylinder 2331. The pressing cylinder mounting plate 2330 is arranged in the mounting door frame 230 along the height direction of the mounting door frame 230. The pressing cylinder 2332 is vertically arranged on the pressing cylinder mounting plate 2330 and is located on one side of the first active roller 231. The movable end of the pressing cylinder 2331 is fixedly connected to the pressing cylinder mounting plate 2330, so that the pressing cylinder 2332 is driven by the pressing cylinder 2331 to approach the direction of the active roller 231 to clamp the pole piece 26, thereby clamping the pole piece 26 and preventing the active roller driving device 232 from slipping when driving the active roller 231 to rotate and drive the pole piece 26 to be transmitted, thereby affecting the transmission of the pole piece 26. It should be noted that the pole piece 26 active roller 231 device has the same structure as the tape active roller device 33, and the structure of the tape active roller device 33 will not be repeated in detail here. The only difference is that the pole piece 26 active roller 231 device is arranged on the first base 20, and the tape active roller device 33 is arranged on the second base 30, and the pole piece 26 active roller 231 device and the tape active roller device 33 are arranged perpendicular to each other.

[0078] like Fig. 9 and 10 As shown, the correcting sliding mechanism 34 includes a correcting driving device (not shown), a connecting reinforcing plate 340, a second guide rail 341 and a second slider 342.
