Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, and in particular to an automatic adhesive application and sampling mechanism for coating electrode sheets. Background Technology

[0002] In the coating process of the lithium battery industry, it is usually necessary to perform online sampling by punching holes in the coated electrode sheets (with tension) to measure the areal density of each sample electrode sheet. The conventional sampling method is manual operation at the sampling point. First, adhesive tape is pasted on the sampling area of ​​the electrode sheet, and the electrode sheet is kept under tension on the conveyor roller. The tape can enhance the tensile strength of the electrode sheet in the sampling area. Then, die-cutting fixtures are used to cut the electrode sheets one by one. The problems are that during the sampling operation, due to the different heights of different operators, it is necessary to climb or two or more people to work together to apply the tape. The tape application time is long and the sampling efficiency is low. The larger the electrode sheet width, the more difficult it is to apply the tape. During operation, it is easy to hit the edge of the electrode sheet, and the electrode sheet is easily damaged due to the tension. Utility Model Content

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] like Figures 1-3This utility model provides an automatic adhesive application and sampling mechanism for coating electrode sheets. It is used to take samples from the electrode sheet 100 and apply adhesive tape 200 to the electrode sheet 100 in a timely manner after sampling, and cut the adhesive tape 200 after the adhesive application is completed, so as to realize the integrated automation of adhesive application and sampling and improve efficiency. The automatic adhesive application and sampling mechanism for coating electrode sheets includes a support, a mounting plate 2, a sampling component 3, an adhesive application component 4, a cutting component 5, and a first driving component 6. The support includes a crossbeam 1 positioned above the electrode sheet 100 to be sampled. The mounting plate 2 is movably mounted on the crossbeam 1, its movement direction parallel to the sampling direction (X-direction) of the electrode sheet 100. The sampling component 3 is mounted on the mounting plate 2 and is used to sample the electrode sheet 100. The adhesive application component 4 is mounted on the mounting plate 2 and positioned at the rear end of the sampling component 3 along the sampling direction (X-direction), and is used to adhere adhesive tape 200 to the sampled electrode sheet 100. The cutting component 5 is mounted on the mounting plate 2 and includes a cutter 51 capable of vertical movement and cutting the adhesive tape 200 during descent. The first driving component 6 is mounted on the crossbeam 1, and its output end is connected to the mounting plate 2 to drive the mounting plate 2 to move on the crossbeam 1.

[0043] The automatic adhesive application and sampling mechanism for coated electrode sheets provided by this utility model is used to automatically apply adhesive and sample coated electrode sheets 100, such as... Figure 2 As shown, the bottom of the electrode 100 is supported on multiple support rollers. A crossbeam 1 spans the electrode 100 along its width and is positioned above it. When the first driving component 6 drives the mounting plate 2 to move or slide along the crossbeam 1, the sampling component 3 and the adhesive application component 4 perform sampling and adhesive application as they move with the mounting plate 2, achieving automated control of adhesive application sampling. This eliminates the need for manual adhesive application, improving efficiency and quality. The sampling component 3 and the adhesive application component 4 are simultaneously positioned on the mounting plate 2, sequentially arranged along the sampling direction. After sampling, the electrode 100 can be promptly adhesive-applied, strengthening the electrode 100 in the sampling area, preventing crack development in the sampling area, and reducing the risk of tape breakage. It should be noted that during adhesive application sampling, the cutting component 5 must be in a non-working position; that is, the cutter 51 only performs the action of cutting the tape 200 after completing one sampling process. Figure 2 As shown, during the process of the mounting plate 2 moving from right to left, the sampling component 3 can take multiple samples on the electrode 100. When the mounting plate 2 moves to the leftmost position, both the sampling component 3 and the adhesive application component 4 leave the electrode 100. At this time, the cutting component 5 performs a cutting action, the cutter 51 descends and cuts the tape 200, and then the cutter 51 rises again to the non-working position. The mounting plate 2 slides back to the initial position in the opposite direction, ready for the next sampling and adhesive application.

[0044] In some embodiments, a lead screw 11 is provided on the crossbeam 1, a nut 12 is threaded onto the lead screw 11, the mounting plate 2 is fixedly connected to the nut 12, and the first driving member 6 is configured to drive the lead screw 11 to rotate and drive the mounting plate 2 to move.

[0045] like Figure 3 As shown, the two ends of the lead screw 11 are rotatably mounted on the end plates at both ends of the crossbeam 1. The first driving member 6 can be a rotary driving mechanism such as a rotary motor. The first driving member 6 drives the lead screw 11 to rotate counterclockwise or clockwise, causing the mounting plate 2 to reciprocate along the lead screw 11 or the crossbeam 1. The nut 12 or the mounting plate 2 is slidably mounted to the crossbeam 1, for example, by setting a slider 14 or a slide rail 13 assembly. By setting the lead screw 11 and nut 12, it is easy to control the reciprocating movement of the mounting plate 2 for multiple adhesive sampling. The lead screw 11 and nut 12 are used to convert the rotation of the first driving member 6 into the movement of the mounting plate 2, requiring little installation space and simplifying control. Of course, in other embodiments, the first driving member 6 can also directly drive the mounting plate 2 to perform linear motion, such as a cylinder. The lead screw 11 and nut 12 can be replaced by a ball screw.

[0046] In some embodiments, the mounting plate 2 includes a horizontal plate 21 and a vertical plate 22 that are perpendicular to each other. The horizontal plate 21 is fixedly connected to the nut 12, and the vertical plate 22 is attached to one side of the beam 1. A sampling component 3, an adhesive component 4 and a cutting component 5 are sequentially arranged on the vertical plate 22 along the sampling direction.

[0047] like Figure 3 As shown, the mounting plate 2 is L-shaped, with the horizontal plate 21 located above the horizontal beam 1 and fixedly connected to the nut 12, and the vertical plate 22 located on one side of the horizontal beam 1. A slider 14 and slide rail 13 mechanism are provided between the horizontal plate 21 and the horizontal beam 1, as shown... Figure 4As shown, two slide rails 13 are arranged on both sides of the lead screw 11 and parallel to the lead screw 11. Two sliders 14 are provided, and the two sliders 14 are fixed to the bottom surface of the cross plate 21. The two sliders 14 are slidably mounted on the two slide rails 13 respectively, realizing the sliding installation between the cross plate 21 and the cross beam 1. The slide rails 13 and sliders 14 can be rectangular in cross section. The lead screw 11 and nut 12 convert the rotation of the first driving member 6 into the movement of the cross plate 21. By sequentially arranging a sampling component 3, an adhesive application component 4, and a cutting component 5 along the sampling direction on the vertical plate 22, when the mounting plate 2 moves along the sampling direction, the first driving component 6 steps the mounting plate 2 to move. A pre-set step distance is used; for each step the mounting plate 2 takes, the sampling component 3 performs a sampling action, and the adhesive application component 4 applies adhesive to the sampling area as the mounting plate 2 continues to move. When the mounting plate 2 moves to the end of the electrode 100, both the sampling component 3 and the adhesive application component 4 disengage from the electrode 100. At this point, the cutter 51 can be driven to descend and cut the adhesive tape 200, completing one adhesive application sampling. Then, the cutter 51 rises, and the first driving component 6 reverses the direction, driving the mounting plate 2 back to the rightmost end, ready for the next sampling movement. The first driving component 6 can be a stepper motor.

[0048] In some embodiments, the sampling component 3 includes a second driving member 31 and a sampling blade 32 disposed at the output end of the second driving member 31. The second driving member 31 is disposed on the vertical plate 22, and the output end of the second driving member 31 is vertically downward and can drive the sampling blade 32 to move up and down to perform interval sampling.

[0049] For example Figure 3 and Figure 4 A sampling base 33 is provided on the vertical plate 22, and the sampling base 33 is set perpendicular to the vertical plate 22. The second driving member 31 is fixed on the sampling base 33. The output end of the second driving member 31 is vertically downward and passes through the sampling base 33 to connect to the sampling blade 32. The second driving member 31 can drive the sampling blade 32 to move up and down. When the first driving member 6 moves step by step, the second driving member 31 drives the sampling blade 32 to retract into the sampling base 33 to avoid scratching the electrode 100. When the first driving member 6 stops after stepping to the preset sampling distance, the second driving member 31 drives the sampling blade 32 to descend and sample the electrode 100 area on the electrode 100. After sampling, it rises again, and the first driving member 6 continues to step to the next sampling area. During the stepping process, the adhesive application component 4 applies adhesive to the sampling area after sampling. This sampling and adhesive application are repeated to automatically complete one sampling process in the width direction of the electrode 100. The sampling base 33 and the vertical plate 22 are detachably connected or are an integral structure.

[0050] In some embodiments, the adhesive application assembly 4 includes a first support rod 41, a third drive member 42, and an adhesive application roller 43. The first support rod 41 is disposed on the vertical plate 22 and perpendicular to the vertical plate 22, and the first support rod 41 is used to rotatably mount the adhesive tape 200. The third drive member 42 is disposed on the vertical plate 22, and the output end of the third drive member 42 is vertically downward. The adhesive application roller 43 is rotatably disposed on the output end of the third drive member 42, and the third drive member 42 can drive the adhesive application roller 43 to descend to abut against the electrode 100 to roll and press one end of the adhesive tape 200.

[0051] like Figure 1 and Figure 3 A base 45 is provided above the horizontal plate 21 to fix the first support rod 41. By setting the base 45, sufficient space can be provided for the installation of the tape roll 200. The tape roll 200 continuously rolls and releases tape 200 during the tape application process. One end of the tape 200 is pre-fixed between the tape roller 43 and the electrode plate 100 and provides appropriate pressure, that is, controlling the descent distance of the tape roller 43 by the third drive component 42 and adjusting the clamping pressure. A base 46 is set on the vertical plate 22, and the third drive component 42 is fixedly set on the base 46. The output end of the third drive component 42 is vertically downward and rotates to install the tape roller 43. The third drive component 42 can be a linear drive mechanism, such as a cylinder or hydraulic cylinder. The adhesive roller 43 is rotatably mounted inside the U-shaped frame 47, which is fixed to the output end of the third drive member 42. Furthermore, to ensure good contact between the adhesive tape 200 and the surface of the electrode 100 during the adhesive application process, the top surface of the U-shaped frame 47 is provided with a first limiting groove 471. The output end of the third drive member 42 is provided with at least one first guide rod 472, preferably two first guide rods 472. The top ends of the two first guide rods 472 are slidably disposed on both sides of the output end of the third drive member 42, and the bottom ends of the two first guide rods 472 are located in the first limiting groove 471. When the output end of the third drive member 42 extends or retracts, the bottom ends of the first guide rods 472 are always located in the first limiting groove 471. The bottom ends of the first guide rods 472 slide relative to the body of the third drive member 42, thereby achieving at least two-point fixation between the output end of the third drive member 42 and the U-shaped frame 47, ensuring the stability of the rolling plane of the adhesive roller 43 during the rolling process, and improving the adhesive application effect.

[0052] In some embodiments, the axial length of the adhesive roller 43 is not less than the width of the tape 200 to ensure that the adhesive roller 43 can press the two ends of the tape 200 and improve the adhesive application effect.

[0053] In some embodiments, the adhesive application assembly 4 further includes a second support rod 44, which is disposed on the vertical plate 22 and parallel to the first support rod 41. One end of the adhesive tape 200 can be wrapped around the second support rod 44 and pressed between the adhesive application roller 43 and the electrode 100.

[0054] like Figure 1 By providing a second support rod 44, one end of the tape 200 is led out from the tape 200 roll, wrapped around the second support rod 44, and fixed between the adhesive roller 43 and the electrode 100, facilitating the release of the tape 200 from the tape roll. In some embodiments, a limiting member is provided at the end of the first support rod 41 facing away from the adhesive base 45 to limit the tape 200 roll on the first support rod 41 and prevent it from slipping and falling. A limiting member can also be provided at the end of the second support rod 44 facing away from the vertical plate 22 to limit the tape 200 and ensure that the tape 200 is in the release direction.

[0055] In some embodiments, there are two second support rods 44, which are spaced apart in the vertical direction and arranged sequentially in the sampling direction.

[0056] For example Figure 1 The projections of the two second support rods 44 and the first support rod 41 onto the horizontal plane along the sampling direction, with the first support rod 41 located between the two second support rods 44, are used to guide the tape 200 to the adhesive roller 43, facilitating the gradual unfolding of the tape 200. Figure 3 One end of the tape 200 is gradually pressed downward between the adhesive roller 43 and the electrode 100 via two second support rods 44, which helps to reduce the tension of the tape 200 and improve the adhesive application effect.

[0057] In some embodiments, the cutting component 5 is disposed at the rear end of the adhesive application component 4 along the sampling direction (X direction).

[0058] like Figure 2 During the sampling process along the sampling direction, the first driving component 6 drives the sampling component 3, the adhesive application component 4, and the cutting component 5 to move synchronously through the mounting plate 2. The cutting component 5 is always in a non-working state during the sampling and adhesive application process. After the sampling and adhesive application are completed, the mounting plate 2 moves to the outside of the electrode 100, and the sampling component 3 and the adhesive application component 4 are detached from the electrode 100. At this time, the cutting component 5 is located above the adhesive tape 200 between the adhesive application roller 43 and the electrode 100. The cutting component 5 is started to cut the adhesive tape 200. This ensures that the adhesive tape 200 is fully adhered to the surface of the electrode 100, and avoids stress expansion in the sampling area of ​​the electrode 100.

[0059] In some embodiments, the cutting assembly 5 includes a fourth drive member 52, a cutter 51 is disposed at the output end of the fourth drive member 52, the fourth drive member 52 is fixed on the vertical plate 22, and the output end of the fourth drive member 52 is vertically downward to drive the cutter 51 to descend and cut the tape 200.

[0060] like Figure 1To simplify the structural design and optimize the design space, the cutting assembly 5 and the adhesive application assembly 4 share a base 46. The fourth drive component 52 is fixed on the base 46. The fourth drive component 52 can be a linear drive mechanism, such as a cylinder. The fourth drive component 52 is used to drive the cutter 51 to move up and down. During the sampling and adhesive application process, the fourth drive component 52 drives the cutter 51 to the raised position. After the sampling and adhesive application is completed, the fourth drive component 52 drives the cutter 51 to descend to cut the tape 200. Figure 5 As shown, similar to the installation of the U-shaped frame 47 in the adhesive application assembly 4, a guide and limiting assembly is provided between the output end of the fourth drive unit 52 and the cutter 51. In this embodiment, the cutter 51 is a serrated blade, and the width of the cutter 51 is not less than the width of the tape 200, so that the cutter 51 can fully contact the tape 200 when it descends and cut it in one go. The guide and limiting assembly includes a second limiting groove 53 provided on the top of the cutter 51 and a second guide rod 54 slidably provided on the fourth drive unit 52. The bottom end of the second guide rod 54 is connected to the second limiting groove 53. The guide and limiting assembly is used to prevent the cutter 51 from deflecting.

[0061] The process of punching and sampling the coated electrode 100 using the automatic adhesive application and sampling mechanism provided in this embodiment is as follows:

[0062] Assemble and install the automatic adhesive application and sampling mechanism for coating the electrode sheet. The first driving component 6 drives the lead screw 11 to rotate and move the mounting plate 2 along the crossbeam 1 to the initial target position. A receiving tray 300 is set below the electrode sheet 100 along the sampling direction.

[0063] Set up a touchscreen communication connection with the first driver 6, the second driver 31, the third driver 42 and the fourth driver 52, and set the sampling interval through the touchscreen;

[0064] The third driving component 42 drives the adhesive roller 43 to descend and presses one end of the adhesive tape 200 onto the surface of the electrode 100.

[0065] The second driving component 31 drives the sampling blade 32 to descend and punch the electrode 100 to obtain the electrode 100 sample;

[0066] The first driving component 6 begins to advance along the sampling direction at a set distance, causing the entire mechanism to move. At the same time, the tape 200 covers the sampling position that has just been punched, ensuring that the tension and toughness of the sampling area are not interrupted.

[0067] The process repeats itself, punching one electrode 100 sample, followed by the application of adhesive roller 43 and adhesive tape 200, which adhere to the punched sampling area. After the last electrode 100 sample is punched, the fourth drive unit 52 drives the cutter 51 to descend and cut the adhesive tape 200. After sampling is completed, the first drive unit 6 drives the mounting plate 2 to automatically return to its initial position.

[0068] In the above-mentioned sampling and adhesive application process, the operator only needs to pre-set the sampling interval and turn on the equipment, and fix the initial position of the adhesive tape 200 between the electrode 100 and the adhesive roller 43. The sampling and adhesive application process does not require manual intervention, which improves the sampling and adhesive application effect and reduces the intensity of manual labor. The sampling area on the punched electrode 100 is promptly coated with adhesive to strengthen the electrode 100, prevent the development of cracks in the punched part, and reduce the risk of tape breakage. After sampling, the electrode 100 samples are taken out sequentially from the receiving tray 300 below the electrode 100, which reduces the risk of tape breakage during the operation.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
