Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to a plastic pressing device for adhesive paper. Background Technology

[0002] Cylindrical battery tabs have an insulating adhesive strip around their edges to prevent the tabs from contacting the casing wall and causing voltage discrepancies. Currently, the industry standard is to wrap an adhesive strip around the edge, and then press the end face together to adhere the adhesive strip to the end face of the tab.

[0003] A battery adhesive applicator, disclosed in CN215377474U, includes a mounting frame, a battery mounting station, a positioning mechanism, an insulating adhesive paper feeding mechanism, an adhesive cutting mechanism, an adhesive pressing mechanism, a first driving mechanism, and an adhesive applicator. During adhesive cutting, the output ends of the adhesive applicator and the adhesive pressing mechanism clamp the lower end of the insulating adhesive paper. During adhesive applicator application, the output end of the adhesive applicator picks up the cut insulating adhesive paper, and the first driving mechanism drives the adhesive applicator to slide to the side of the battery mounting station and apply the insulating adhesive paper to a predetermined position on the battery.

[0004] Existing adhesive bonding methods all use a sleeve-type guide. The battery is lifted upwards and bends the adhesive paper through the guide groove. It continues to be lifted until the adhesive bonding platform presses the adhesive paper firmly. However, in this method, the adhesive bonding surface is in rigid contact with the core, which can easily damage the core and cause the battery to short circuit. Furthermore, if the stroke is too small, the adhesive paper cannot be properly adhered, resulting in a rebound phenomenon after the adhesive paper is pressed. Also, the rigid contact leads to uneven adhesive bonding, and some areas may not be in contact with the adhesive bonding surface due to dimensional tolerances, resulting in poor adhesive bonding effect, affecting subsequent processing and increasing the risk of short circuits in the battery itself.

[0036] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0037] like Figure 1-6As shown, this utility model discloses a plastic pressing device for adhesive tape, comprising a base plate 1, an adhesive feeding tray 2, a plasticizing mechanism 3, a supporting mechanism 4, and a pressing mechanism 5. The adhesive feeding tray 2 is rotatably connected to the base plate 1, and adhesive tape is wound onto the adhesive feeding tray 2 for unwinding. The plasticizing mechanism 3 is disposed on the base plate 1 and located on the unwinding side of the adhesive feeding tray 2. The plasticizing mechanism 3 has a plasticizing channel 300, through which the adhesive tape abuts and passes, causing the adhesive tape to bend and plasticize upon heating. The supporting mechanism 4 is disposed on the base plate 1 and located on the side of the plasticizing mechanism 3 away from the adhesive feeding tray 2. The supporting mechanism 4 has a circumferentially rotatable elastic support portion for placing the battery cell. The pressing mechanism 5 is disposed on the base plate 1 and located outside the supporting mechanism 4. The pressing mechanism 5 has a pressing portion that abuts against the end face of the battery cell, fixing the battery cell and pressing the adhesive tape onto the end face of the battery cell.

[0038] It should be noted that the adhesive tape is wound on the glue-dispensing tray 2, which is rotatably connected to the base plate 1. During the rotation of the glue-dispensing tray 2, the adhesive tape is unwound. The adhesive tape is released from the glue-dispensing tray 2 and first passes through the plastic channel 300. The plastic mechanism 3 heats the adhesive tape and causes local bending and plastic deformation in the middle of the adhesive tape. The support mechanism 4 is provided with a circumferentially rotatable elastic support part for placing the battery cell. The battery cell is fixed by the pressing part abutting against the end face of the battery cell. The adhesive tape passes through the pressing part and the end face of the battery cell and is fixed to the battery cell. The circumferential rotation of the elastic support part presses the plasticized adhesive tape onto the end face of the battery cell, thus completing the purpose of pressing the adhesive tape onto the battery cell.

[0039] In this embodiment, the adhesive paper is heated and plasticized by the plasticizing mechanism 3, causing local bending and plastic deformation in the middle of the adhesive paper, so that it can be perfectly attached to the end face of the battery cell without lifting up and affecting subsequent processing and the risk of short circuit in the battery itself. The unwinding, plasticizing, supporting and pressing of the adhesive paper are integrated by the adhesive unwinding tray 2, the supporting mechanism 4 and the pressing mechanism 5, which improves production efficiency.

[0040] In a preferred embodiment, the plasticizing mechanism 3 includes a first driving member 31, a roller member 32, a heating ring 33, and a plasticizing pressure roller 34. The first driving member 31 is fixed to the base plate 1. The roller member 32 is fixed to the output shaft of the first driving member 32. The heating ring 33 is sleeved and fixed to the outside of the roller member 32. The plasticizing pressure roller 34 is rotatably connected to the base plate 1, and the plasticizing pressure roller 34 and the heating ring 33 are arranged opposite to each other and spaced apart to form a plasticizing channel 300. The two sides of the adhesive paper abut against the surfaces of the heating ring 33 and the plasticizing pressure roller 34, respectively.

[0041] It should be noted that when the first driving component 31 is started, the roller component 32 rotates accordingly, driving the heating ring 33 to rotate. After the adhesive paper is unwound from the adhesive tray 2, it passes through the plastic channel 300, and its two sides abut against the surfaces of the heating ring 33 and the plastic pressure roller 34 respectively. Under the heating action of the heating ring 33, the adhesive paper softens locally. The plastic pressure roller 34 causes the adhesive paper to undergo local bending plastic deformation in the middle through pressure, forming the required shape.

[0042] In this embodiment, the heating ring 33 and the plastic pressure roller 34 work together to plastically deform the adhesive paper. The plasticized adhesive paper can better adhere to the end face of the battery cell, reduce lifting and rebound, and improve the adhesion.

[0043] In addition, the coaxiality between the heating ring 33 and the roller 32 is ≤0.05mm; and according to different adhesive paper materials, different temperatures are controlled by the temperature controller to heat and plasticize the local adhesive paper. The roller 32 is equipped with a temperature detection sensor to detect the temperature of the heating ring 33, and the heating ring 33 is controlled by an external temperature controller to heat and plasticize the local adhesive paper at different temperatures.

[0044] In a preferred embodiment, the plastic pressure roller 34 includes a cylindrical section 341 and a conical section 342. The cylindrical section 341 is rotatably connected to the base plate 1 and is perpendicular to the base plate 1. The conical section 342 is fixed to the end of the cylindrical section 341, and the outer side of the conical section 342 is inclined towards the heating ring 33 at a 45° angle.

[0045] It should be noted that by setting the tapered section 342 at a 45° angle, the adhesive tape can better adhere to the end face of the battery cell during the molding process, reducing the gap between the adhesive tape and the end face of the battery cell, improving the tightness and uniformity of the adhesion, and thus reducing the risk of battery short circuit.

[0046] In a preferred embodiment, the support mechanism 4 includes a second drive member 41, a chassis 42, a plurality of spring assemblies 43, and a carrier plate 44. The second drive member 41 is fixed to the base plate 1, and the chassis 42 is fixed to the output shaft of the second drive member 41. The plurality of spring assemblies 43 are evenly arranged on the side of the chassis 42 away from the second drive member 41 to ensure that the end face of the battery cell is always in contact with the pressing part. The carrier plate 44 is fixed on the plurality of spring assemblies 43, and the inner contour cross-sectional shape of the carrier plate 44 matches the outer contour cross-sectional shape of the battery cell to place and position the battery cell.

[0047] It should be noted that the inner contour cross-sectional shape of the carrier plate 44 matches the outer contour cross-sectional shape of the battery cell, ensuring that the battery cell can be accurately positioned when placed on the carrier plate 44, avoiding movement or misalignment of the battery cell during the pressing process, thereby improving the accuracy and consistency of the pressing. Furthermore, the spring assembly 43 gives the carrier plate 44 a certain degree of elasticity, providing stable support for the battery cell during the pressing process. At the same time, the elasticity of the spring assembly 43 allows the carrier plate 44 to adaptively adjust with the changes in the end face of the battery cell, ensuring that the end face of the battery cell is always in contact with the pressing part. This improves the tightness and uniformity of the pressing and reduces pressing defects caused by unevenness of the end face of the battery cell.

[0048] In a preferred embodiment, each spring assembly 43 in this embodiment includes a telescopic rod 431, an elastic element 432, and a sleeve 433. The telescopic rod 431 is fixed on the side of the chassis 42 away from the second driving member 41. The sleeve 433 is sleeved on the outside of the telescopic rod 431 and is slidably connected to the telescopic rod 431. The elastic element 432 is disposed inside the sleeve 433. One end of the telescopic rod 431 passes through and extends into the sleeve 433 and is fixedly connected to the end face of the elastic element 432.

[0049] It should be noted that the telescopic rod 431 extends into the sleeve 433, and a limiting part is provided between the telescopic rod 431 and the sleeve 433 to prevent the telescopic rod 431 from disengaging from the sleeve 433 and to ensure the normal use of the spring assembly 43.

[0050] In a preferred embodiment, the pressing mechanism 5 includes a pushing member 51, a mounting member 52, a first right-angle pressing roller 53, and a second right-angle pressing roller 54. The pushing member 51 is fixed to the base plate 1, and the mounting member 52 is fixed to the telescopic end of the pushing member 51. The first right-angle pressing roller 53 is rotatably connected to the mounting member 52 and is perpendicular to the pushing direction of the pushing member 51. The pushing member 51 pushes the first right-angle pressing roller 53 to abut against the end face of the battery cell. The second right-angle pressing roller 54 is rotatably connected to the base plate 1 and is opposite to the first right-angle pressing roller 53, and the second right-angle pressing roller 54 abuts against the end face of the battery cell.

[0051] It should be noted that when the pressing mechanism 5 in this embodiment is working, the pusher 51 starts and drives its telescopic end to move the mounting part 52, thereby causing the first right-angle pressure roller 53, which is rotatably connected to the mounting part 52, to approach and abut against the end face of the battery cell. At the same time, the second right-angle pressure roller 54, which is arranged opposite to it, also abuts against the end face of the battery cell. The two work together to apply uniform pressure to the plasticized adhesive paper, and the battery cell rotates circumferentially to press it tightly against the end face of the battery cell, thus completing the pressing process.

[0052] In this embodiment, through the synergistic action of the first right-angle pressure roller 53 and the second right-angle pressure roller 54, the adhesive tape can be pressed evenly and tightly onto the end face of the battery cell, improving the quality and stability of the adhesive pressing. The adhesive pressing mechanism 5 makes the adhesive pressing process more efficient. The synergistic action of the pusher 51 and the first right-angle pressure roller 53 and the second right-angle pressure roller 54 greatly shortens the adhesive pressing time and improves production efficiency.

[0053] In addition, the first right-angle pressure roller 53 and the second right-angle pressure roller 54 in this embodiment both include a cylindrical section 501 and a pressing section 502. The pressing section 502 is fixed relative to the side of the cylindrical section 501 away from the bottom plate 1, and the diameter of the pressing section 502 is larger than the diameter of the cylindrical section 501. The cylindrical section 501 abuts against the side of the battery cell, and the pressing section 502 abuts against the end face of the battery cell.

[0054] It should be noted that during the pressing process, the first right-angle pressure roller 53 moves towards the battery cell through the drive of the pusher 51. The cylindrical section 501, as a support structure, fits tightly against the side of the battery cell, providing lateral positioning and support. The lower pressing section 502, with its diameter larger than that of the cylindrical section 501, applies uniform pressure to the end face of the battery cell in the vertical direction, pressing the adhesive paper firmly onto the end face. The two work together, with the cylindrical section 501 controlling the lateral position of the battery cell and the lower pressing section 502 completing the end face pressing, forming a three-dimensional pressing path.

[0055] In this embodiment, the first right-angle pressure roller 53 and the second right-angle pressure roller 54 are set through the cylinder section 501 and the lower pressure section 502 to realize the dual functions of lateral positioning and end face pressure during the adhesive pressing process, which improves the adhesive pressing accuracy and optimizes the structural stability.

[0056] This embodiment also includes a first guide member 6 and a second guide member 7. The first guide member 6 and the second guide member 7 are both fixed on the base plate 1. The first guide member 6 is located between the glue dispensing tray 2 and the plastic pressure roller 34 and is used to guide the unwound adhesive paper. The second guide member 7 is located between the plastic pressure roller 34 and the second right-angle pressure roller 54 and is used to guide the plasticized adhesive paper.

[0057] It should be noted that in this embodiment, the first guide member 6 guides the adhesive paper unwound from the adhesive tray 2 to ensure that the adhesive paper can enter the working area of ​​the plastic pressure roller 34 smoothly and accurately; the second guide member 7 guides the adhesive paper after it has been plasticized by the plastic pressure roller 34, so that the adhesive paper can accurately reach the second right-angle pressure roller 54 for the final pressing operation; through the guidance of the first guide member 6 and the second guide member 7, the adhesive paper can maintain a stable path during the conveying process, reducing the problem of poor pressing caused by adhesive paper deviation or shaking, and improving the accuracy and consistency of pressing.

[0058] In this embodiment, both the first guide member 6 and the second guide member 7 include a vertical section 801, an inclined section 802, and a support section 803. The vertical section 801 is fixed to the base plate 1, the inclined section 802 is fixed to the side of the vertical section 801 away from the base plate 1, and the inclined section 802 is inclined toward the adhesive paper side; the support section 803 is fixed to the side of the vertical section 801 close to the plastic mechanism 3, and the bottom end of the adhesive paper abuts against the inner wall of the support section 803 to support the adhesive paper.

[0059] Specifically, in this embodiment, the inclined section 802 and the vertical section 801 of the first guide member 6 form a 70° angle; the inclined section 802 and the vertical section 801 of the second guide member 7 form a 45° angle.

[0060] It should be noted that, in this embodiment, the inclined section 802 and the vertical section 801 of the first guide member 6 form a 70° angle, which is beneficial for changing the shape of the adhesive paper after it is released from the adhesive tray 2; the inclined section 802 and the vertical section 801 of the second guide member 7 form a 45° angle, which is more suitable for guiding the adhesive paper again after it has been plasticized, so that it can reach the second right-angle pressure roller 54 for the final pressing operation.

[0061] Working principle:

[0062] The glue unwinding tray 2 is rotatably connected to the base plate 1. The adhesive paper is wound around it and rotates with it to achieve unwinding. After unwinding, the adhesive paper is guided by the first guide 6 and enters the plastic mechanism 3.

[0063] In the plastic mechanism 3, the first driving member 31 drives the roller member 32 and the heating ring 33 to rotate. The two sides of the adhesive paper abut against the surfaces of the heating ring 33 and the plastic pressure roller 34 respectively. After being heated and softened by the heating ring 33, the adhesive paper undergoes local bending and plastic deformation in the middle due to the pressure of the plastic pressure roller 34.

[0064] Subsequently, the molded adhesive tape is guided by the second guide member 7 and passes through the carrier plate 44 in the support mechanism 4, which matches the outer contour of the battery cell and is supported by the spring assembly 43. At this time, the push member 51 of the pressing mechanism 5 drives the mounting member 52 to move, so that the first right-angle pressing roller 53 abuts against the end face of the battery cell, and at the same time, the second right-angle pressing roller 54 also abuts against the end face of the battery cell. The two work together with the carrier plate 44 on the support mechanism 4, which is driven to rotate by the second drive member 41, to drive the battery cell to rotate circumferentially, and press the adhesive tape evenly and tightly onto the end face of the battery cell to complete the pressing.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
