[0032] 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.

[0033] Reference Figure 1 An automatic film feeding mechanism includes: a turret assembly 100, two sets of first film suction assemblies 200, a second film suction assembly 300, and a third film suction assembly 400.

[0034] Reference Figure 1-8 The turret assembly 100 is equipped with a replacement roll 120 and a replacement roll 130. Two sets of first suction film assemblies 200 are installed on the upper and lower ends of the turret assembly 100. Each first suction film assembly 200 includes a first suction plate 210. The second suction film assembly 300 includes a second suction plate 310 and a cutting blade 320. The third suction film assembly 400 includes a third suction plate 410 and an adhesive applicator 470. The second suction plate 310 and the third suction plate 410 are arranged opposite to each other to cooperate in pressing down the material strip of the replacement roll 120, ensuring that the material strip remains stable during the cutting process. The cutting blade 320 is arranged above the second suction plate 310 and is used to cut along the length direction of the second suction plate 310. The material strip above the second adsorption plate 310 cuts the material strip of the replacement roll 120. After the material strip is cut, it drives the second adsorption plate 310 to separate from the third adsorption plate 410. The adhesive applicator 470 is used to attach a connecting material to the third adsorption plate 410 after the second adsorption plate 310 and the third adsorption plate 410 are separated. The turret assembly 100 is provided with roll mounting positions for installing the replacement roll 120 and the replacement roll 130 respectively. The turret assembly 100 can rotate to rotate the replacement roll 130 to the feeding position 110. The first adsorption plate 210 is used to press the material strip of the replacement roll 130 onto the third adsorption plate 410, so that the two material strips are connected together by the connecting material. For example, in a battery electrode production line, when the roll is about to run out, this mechanism can automatically connect a new roll to the roll that is about to run out without manual intervention, which greatly improves production efficiency and operational safety.

[0035] The connecting material can be single-sided tape, conductive tape, heat-pressed laminating film, etc. Different connecting materials can be formulated according to specific production needs, such as using different tapes. In this case, the preferred connecting material is single-sided tape, with the non-adhesive side of the single-sided tape facing the third adsorption plate 410. It can be understood that the adhesive applicator 470 is used to attach the connecting material to the third adsorption plate 410 after the second adsorption plate 310 and the third adsorption plate 410 are separated. At this time, the connecting material is single-sided tape, and the non-adhesive side faces the third adsorption plate 410. The single-sided tape is then adsorbed by the adsorption capacity of the third adsorption plate 410. In subsequent processes, the tape of the replacement roll 130 is pressed onto the adsorbed single-sided tape on the third adsorption plate 410 through the first adsorption plate 210, so that the tape and the adhesive side of the single-sided tape are tightly bonded.

[0036] In some embodiments, refer to Figure 1 , 7 8. Below the third suction film assembly 400, a belt pressing roller assembly 500 is installed. This assembly consists of three parts: a roller 510, a pressure bar 520, and a belt pressing cylinder 530, which work together to control the conveying path of the material belt. Specifically, the roller 510 and pressure bar 520 are located on opposite sides of the material belt conveying path. When the material belt is being conveyed normally, the belt pressing cylinder 530 drives the pressure bar 520 to move towards the roller 510, creating a controlled pressing area between the roller 510 and the pressure bar 520. This prevents the material belt from being accidentally pulled away due to tension or equipment vibration after the cutting operation, ensuring that the end of the material roll 120 to be replaced can be stably held on the third suction plate 410 for subsequent connection operations.

[0037] In some embodiments, refer to Figure 2 , 8The first suction film assembly 200 also includes a first rodless cylinder 220, which drives the first adsorption plate 210 to move. It should be noted that the first adsorption plate 210 positions and presses the material strip of the replacement roll 130 into the connection position. When the turret assembly 100 rotates, rotating the replacement roll 130 to the feeding position 110, the first rodless cylinder 220 drives the first adsorption plate 210 closer to the third adsorption plate 410, and bonds and fixes the material strip of the replacement roll 130 to the connecting material on the third adsorption plate 410. It should be noted that at this time, the end of the raw material strip of the replacement roll 120 is bonded to the third adsorption plate 410 by the connecting material. After the first adsorption plate 210 presses the material strip of the replacement roll 130 onto the third adsorption plate 410, the material strip of the replacement roll 130 and the raw material strip are firmly connected, forming a continuous feeding channel. Subsequently, the first adsorption plate 210, the second adsorption plate 310 and the third adsorption plate 410 stop adsorption, and the first adsorption plate 210 is driven back to its original position by the first rodless cylinder 220. At this time, the replacement roll 130 begins to unwind and feed material normally. After the replacement roll 120 is removed by the operator, the equipment can continue to prepare for the next round of tape connection operation.

[0038] Furthermore, to ensure the stability and accuracy of the first film suction assembly 200 during movement, guide rods 230 are provided on both sides of the first rodless cylinder 220. Specifically, when the first rodless cylinder 220 drives the first adsorption plate 210 to move towards the third adsorption plate 410, these guide rods 230 provide additional support and guidance, preventing the first adsorption plate 210 from swaying, shifting, or tilting during movement, thereby ensuring that the first film suction assembly 200 maintains a stable movement trajectory and posture throughout the entire driving process.

[0039] In some embodiments, refer to Figure 3 , 4 The second suction assembly 300 further includes a second rodless cylinder 330, a first thin cylinder 340, a second thin cylinder 350, a third thin cylinder 360, and a third rodless cylinder 370. The second rodless cylinder 330 drives the first thin cylinder 340 and the second thin cylinder 350 to move vertically. Specifically, the output end of the second rodless cylinder 330 is provided with a mounting plate, on which the first thin cylinder 340 and the second thin cylinder 350 are mounted. In this case, the first thin cylinder 340 and the second thin cylinder 350 can be individually controlled to extend and retract their output ends, achieving independent positioning of the second suction plate 310 and the third rodless cylinder 370. Through the vertical driving of the second rodless cylinder 330, overall height adjustment is achieved during the material strip pressing and cutting process, ensuring that each functional component maintains the optimal working distance with the material strip on the third suction plate 410, improving the accuracy and reliability of the strip splicing operation.

[0040] Furthermore, after the height is adjusted vertically by the second rodless cylinder 330, the first thin cylinder 340 is connected to the second adsorption plate 310 to drive the second adsorption plate 310 to cooperate with the third adsorption plate 410 to press and fix the material strip, so that the subsequent cutting operation can be carried out in a stable state. The second thin cylinder 350 is connected to the third rodless cylinder 370 to drive the third rodless cylinder 370 to extend and approach the third adsorption plate 410; the third rodless cylinder 370 is connected to the third thin cylinder 360 to drive the third thin cylinder 360 to move along the extension direction of the second adsorption plate 310; the third thin cylinder 360 is connected to the cutting blade 320 to drive the cutting blade 320 to approach the third adsorption plate 410 to cut the material strip fixed on the third adsorption plate 410. The specific operation process is as follows: First, the cutting blade 320 is adjusted to an appropriate height by the second rodless cylinder 330. Then, the first thin cylinder 340 drives the second adsorption plate 310 and the third adsorption plate 410 to clamp the material strip, ensuring that the material strip remains stable and does not move during the cutting process. Next, the second thin cylinder 350 drives the third rodless cylinder 370 to extend forward to the cutting position, so that the cutting mechanism is close to the fixed material strip. Finally, the third thin cylinder 360 drives the cutting blade 320 to further fine-tune its position. Then, the third rodless cylinder 370 drives the third thin cylinder 360 to move smoothly along the width direction of the material strip, thereby driving the cutting blade 320 to cut the material strip, realizing a flat break of the material strip, preparing for the subsequent strip splicing process, and ensuring that the new and old material strips can be seamlessly connected.

[0041] Furthermore, driven by the third rodless cylinder 370, the cutting blade 320 adheres to the surface of the second adsorption plate 310, causing it to move along the surface of the second adsorption plate 310 to cut the material strip. Since the second adsorption plate 310, in conjunction with the third adsorption plate 410, has pressed and fixed the material strip, a flat cutting plane is formed on the surface of the material strip. The movement of the cutting blade 320 against the surface of the second adsorption plate 310 ensures a consistent cutting path. This allows the cutting blade 320 to cut the material strip with constant pressure and angle as it moves along the surface of the second adsorption plate 310, avoiding problems such as uneven cutting depth or cutting path deviation.

[0042] Furthermore, refer to Figure 4A gap 411 is provided on the third adsorption plate 410 along its length. Specifically, the third adsorption plate 410 can be formed by splicing two adsorption plates, with a gap 411 at the splice for the cutting blade 320 to pass through. The gap 411 is divided into a first adsorption side 412 at the top and a second adsorption side 413 at the bottom. During cutting, the second adsorption plate 310 and the second adsorption side 413 cooperate to press the material strip, and the cutting blade 320 can be inserted into the gap, thereby achieving complete cutting of the material strip without damaging the surface of the third adsorption plate 410. At the same time, due to the effective clamping of the material strip by the second adsorption plate 310 and the second adsorption side 413, it is ensured that the material strip will not be lifted or shifted during the cutting process, ensuring the accuracy and flatness of the cut.

[0043] In some embodiments, refer to Figure 5 , 6 The third film suction assembly 400 includes a bracket 420, a long cylinder 430, a mounting arm 440, a pen-shaped cylinder 450, and a linear module 460. The bracket 420 serves as the basic structure of the entire third film suction assembly 400, providing a stable mounting platform. The long cylinder 430 is located in the middle of the bracket 420 and is responsible for driving the mounting arm 440 to extend and retract. The mounting arm 440 is connected to the long cylinder 430 and is movably connected to the third suction plate 410, facilitating the extension and retraction of the third suction plate 410. Angle adjustment; one end of the pen-shaped cylinder 450 is connected to the mounting arm 440, and the other end is connected to the third adsorption plate 410. The pen-shaped cylinder 450 controls the rotation of the third adsorption plate 410 by telescopic control, thereby realizing the posture adjustment of the third adsorption plate 410 in different working states; the linear module 460 is set at the top of the bracket 420 and is used to drive the adhesive applicator 470 to move along the length direction of the third adsorption plate 410 to attach the bonding material to the third adsorption plate 410.

[0044] Furthermore, refer to Figure 6The linear module 460 includes a first slide rail 461 and a first slide table 462. The first slide table 462 slides in conjunction with the first slide rail 461 to provide horizontal motion control. The adhesive applicator 470 consists of a second slide rail 471, a second slide table 472, a fourth thin cylinder 473, and an adhesive applicator head 474. The second slide rail 471 is vertically fixed on the first slide table 462, and the second slide table 472 slides in conjunction with the second slide rail 471 to achieve vertical movement. The fourth thin cylinder 473 is disposed on the first slide table 462, and its output end is connected to the second slide table 472. The extension and retraction of the fourth thin cylinder 473 drives the second slide table 472 to slide vertically relative to the second slide rail 471. The adhesive applicator head 474 is mounted on the second slide table 472. As the second slide table 472 moves up and down, the distance between the adhesive applicator head 474 and the third adsorption plate 410 can be precisely adjusted.

[0045] Further, continue to refer to Figure 6 The adhesive applicator 474 includes an adhesive guide rod 4741 and a fifth thin cylinder 4743. One end of the adhesive guide rod 4741 is movably connected to the second slide table 472, ensuring that the angle of the adhesive guide rod 4741 can be adjusted. The other end of the adhesive guide rod 4741 is provided with an adhesive guide roller 4742, which is used to guide the adhesive tape to be smoothly attached to the material belt. The fifth thin cylinder 4743 is fixedly installed on the second slide table 472, and its output end is movably connected to the side of the adhesive guide rod 4741 near the adhesive guide roller 4742. The position of the adhesive guide rod 4741 can be precisely controlled by the extension and retraction movement of the fifth thin cylinder 4743, thereby realizing the fine adjustment of the distance between the adhesive guide roller 4742 and the third adsorption plate 410.
