Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a tape shaping device and a production line. Background Art

[0002] During the production of lithium batteries, blue glue needs to be attached after the top cover and the battery cell are laser welded to isolate the conductive areas of the tabs, connecting pieces and top cover from the pole pieces of the battery cell after the battery cell is assembled, to prevent the tabs, connecting pieces and conductive areas of the top cover from short-circuiting after they come into contact with the pole pieces in the battery cell. Usually, the adhesive tape is U-shaped, and the bottom of the tape is covered with glue, which makes it very easy for the glue-coated part of the tape to interfere with the winding core when the tape is inserted into the gap between the connecting parts of the two winding cores, resulting in poor adhesion of the tape.

[0003] The traditional glue sticking method is to directly stick the glue to the battery cell after the glue sucker takes the glue. After the glue is stuck, the glue is deformed randomly when the AB surface of the battery cell is assembled. After the battery cell is assembled, the bending state of the PET glue is poorly consistent, so the consistency of the support state of the battery cell tab is poor, which increases the risk of short circuit caused by the bending of the tab into the battery cell. The existing equipment bends the glue before sticking it, so that creases are formed on the glue to reduce the probability of poor sticking during the glue sticking process. However, the glue is elastic and will rebound after bending, resulting in poor sticking of the glue. Utility Model Content

DETAILED DESCRIPTION

[0032] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] A preferred embodiment of the adhesive tape shaping device of the utility model is as follows Figures 1 to 9 As shown, the adhesive tape shaping device includes a base 1, an adhesive head 2, a floating block 3, a shaping block 4 and a hot stamping block 5. The base 1 forms an assembly basis, and the floating block 3, the shaping block 4 and the hot stamping block 5 are all assembled on the base 1. The adhesive head 2 is used to absorb the adhesive tape by means of negative pressure.

[0034] The base 1 has a first direction Z and a second direction Y intersecting each other. In this embodiment, the first direction Z and the second direction Y are perpendicular to each other. The glue dispensing head 2 and the base 1 are arranged at intervals along the first direction Z. The glue dispensing head 2 can move along the first direction Z to approach or move away from the base 1. The floating block 3 is floatingly assembled on the base 1 along the first direction Z. When the glue dispensing head 2 moves along the first direction Z, the adhesive tape can be abutted against the floating block 3 to fix the adhesive tape during the process of shaping the adhesive tape and prevent the adhesive tape from moving.

[0035] The adhesive head 2 has an adsorption surface 21 and a bending surface 22. The adsorption surface 21 is arranged toward the base 1, and the bending surface 22 is located on the side of the adsorption surface 21 away from the base 1. There is an angle between the bending surface 22 and the adsorption surface 21, and the angle is an acute angle. The adsorption surface 21 has a negative pressure hole 23, and the negative pressure hole 23 is used to connect with an external vacuum device, so that negative pressure is generated in the negative pressure hole 23 of the adsorption surface 21, and the adhesive tape to be bent and shaped is adsorbed and fixed by negative pressure.

[0036] The bending surface 22 is used for the adhesive tape to be bent and then adhered, so that both sides of the adhesive tape are squeezed between the shaping block 4 and the bending surface 22, and the adhesive tape is shaped into a shape with different angles. For adhesive tapes with different shaping angles, the glue-taking head 2 with different angles between the adsorption surface 21 and the bending surface 22 can be replaced to complete the shaping and bending of the adhesive tape at different angles.

[0037] The glue-taking head 2 can move along the first direction Z. The glue-taking head 2 has a high position and a low position during the moving stroke. The glue-taking head 2 is at the high position when it is far from the base 1, and the glue-taking head 2 is at the low position when it is close to the base 1. The glue-taking head 2 is at the high position in the initial state and can adsorb the adhesive tape to be bent or transfer the already bent adhesive tape; when bending the adhesive tape, the glue-taking head 2 moves to the low position, and the adhesive tape is clamped and fixed between the adsorption surface 21 and the floating block 3.

[0038] The floating block 3 is floatingly assembled on the base 1 along the first direction Z. One side of the floating block 3 facing the glue-taking head 2 has a supporting surface 31, and the supporting surface 31 is used for supporting the adhesive tape when shaping the adhesive tape. When the glue-taking head 2 moves to the low position, the adsorption surface 21 presses the adhesive tape tightly on the supporting surface 31, and the adhesive tape is fixed by the clamping force to prevent the adhesive tape from moving during bending. In this embodiment, the height of the supporting surface 31 of the floating block 3 is slightly higher than the height of the shaping block 4 in the initial state, so that the glue-taking head 2 can contact the supporting surface 31 of the floating block 3 in advance to press the adhesive tape tightly when moving to the low position; and the floating distance of the floating block 3 is greater than the distance between the shaping block 4 and the hot stamping block 5, so that the adsorption surface 21 of the glue-taking head 2 can move to the position of the heating groove 51 of the hot stamping block 5 along the first direction Z.

[0039] The shaping block 4 has a shaping surface 41, and the shaping surface 41 is parallel to the bending surface 22 of the glue-taking head 2. The shaping block 4 is movably assembled on the base 1 along the second direction Y. There are two groups of shaping blocks 4, and the two groups of shaping blocks 4 are symmetrically arranged on the base 1 along the second direction Y, and the shaping surfaces 41 of the two groups of shaping blocks 4 are arranged oppositely. The shaping block 4 has an open state away from the glue-taking head 2 and a contracted state close to the glue-taking head 2 during the moving stroke. When the shaping block 4 is in the contracted state, the shaping surface 41 is attached to the bending surface 22 of the glue-taking head 2 at the low position, and the side edge of the adhesive tape can be bent and clamped on the bending surface 22, and the shaping surface 41 and the bending surface 22 are used for shaping and positioning the adhesive tape.

[0040] When shaping the adhesive tape, the two groups of shaping blocks 4 are in an open state. At this time, the distance between the two groups of shaping blocks 4 is slightly larger than the size of the glue pickup head 2 in the second direction Y. The glue pickup head 2 moves from a high position to a low position, and both sides of the adhesive tape adsorbed on the adsorption surface 21 come into contact with the shaping blocks 4. The shaping blocks 4 initially fold both sides of the adhesive tape towards the first direction Z; in this embodiment, the distance between the two groups of shaping blocks 4 in the open state is 3-5 mm larger than the width of the glue pickup head 2, which can not only prevent the glue pickup head 2 from hitting the shaping blocks 4 when moving, but also ensure the shaping effect. When the glue pickup head 2 moves to the low position, the shaping blocks 4 move along the second direction Y and move from the open state to the contracted state. At this time, the shaping surface 41 presses the preliminarily bent adhesive tape against the bending surface 22.

[0041] The hot stamping block 5 is fixedly assembled on one side of the shaping block 4 close to the base 1. The hot stamping block 5 has a heating groove 51, and the heating groove 51 is located on the side of the hot stamping block 5 close to the shaping surface 41. The hot stamping block 5 is fixedly assembled with the shaping block 4. When the shaping block 4 moves along the second direction Y, it can drive the hot stamping block 5 to move synchronously. When the shaping block 4 moves to the contracted state, the connection part between the bending surface 22 and the adsorption surface 21 of the glue pickup head 2 is embedded in the heating groove 51. At this time, the crease of the adhesive tape is located in the heating groove 51, and the hot stamping block 5 directly heats the crease of the adhesive tape. After the hot stamping is in place, the adhesive tape cools and is shaped, improving the heating efficiency and also preventing the crease from rebounding after shaping.

[0042] The adhesive tape shaping device is provided with negative pressure holes 23 on the adsorption surface 21 of the glue pickup head 2. Using the negative pressure holes 23 to adsorb the adhesive tape can realize the transfer of the adhesive tape. When the glue pickup head 2 moves from a high position to a low position in the first direction Z, the adsorption surface 21 fits with the support surface 31 on the floating block 3, and the adhesive tape is squeezed and fixed between the glue pickup head 2 and the floating block 3. The shaping blocks 4 move from the open state along the second direction Y to the contracted state, and the shaping surface 41 fits with the bending surface 22, which can bend and fix the edge part of the adhesive tape between the shaping surface 41 and the bending surface 22. The shaping blocks 4, the floating block 3 and the glue pickup head 2 are used to fix and shape the adhesive tape. The hot stamping block 5 is fixedly assembled on the shaping block 4. When the shaping block 4 moves to the contracted state, the connection part between the bending surface 22 and the adsorption surface 21 is embedded in the heating groove 51 of the hot stamping block 5, and the heating groove 51 directly heats the folded corner of the adhesive tape, ensuring the shaping effect at the folded corner of the adhesive tape, preventing the adhesive tape from rebounding after being bent, and the adhesive tape can maintain a fixed angle for attachment after cooling, reducing the risk of cracked pole ears after the battery cores are combined.

[0043] Preferably, the heating groove 51 has a side wall 52 and a bottom wall 53, and the side wall 52 and the bottom wall 53 are perpendicular to each other.

[0044] The side wall 52 and the bottom wall 53 of the heating groove 51 are perpendicular to each other, and the heating groove 51 is an overall rectangular notch structure, which simplifies the structure of the heating groove 51 and is convenient for processing and forming.

[0045] Preferably, the heating groove 51 has a side wall 52 and a bottom wall 53 , the side wall 52 and the bending surface 22 are parallel to each other, and the bottom wall 53 and the adsorption surface 21 are parallel to each other.

[0046] like Figure 10 As shown, the side wall 52 of the heating groove 51 is parallel to the bending surface 22 of the glue dispensing head 2, and the bottom wall 53 is parallel to the adsorption surface 21, so that the heating groove 51 and the glue dispensing head 2 are contoured structures, increasing the contact area between the side wall 52 and the bottom wall 53 of the heating groove 51 and the fold of the adhesive paper, thereby improving the heating efficiency and shaping effect.

[0047] Preferably, the hot stamping block 5 comprises a heat conducting block 54 and an electric heating rod 55 , the electric heating rod 55 is inserted into the heat conducting block 54 , and the heating groove 51 is opened at the end of the heat conducting block 54 close to the shaping block 4 .

[0048] The hot stamping block 5 is formed by a heat conducting block 54 and an electric heating rod 55. After the electric heating rod 55 is heated, the heat can be transferred to the heat conducting block 54, so that the heating groove 51 of the heat conducting block 54 heats the adhesive tape. After the heat conducting block 54 is heated, the heat at each location is more uniform, ensuring that the bending angles at each location of the adhesive tape fold are uniform. In this embodiment, the heat conducting block 54 is made of stainless steel.

[0049] Preferably, the shaping block 4 includes a first side plate 42 and a second side plate 43, the first side plate 42 and the second side plate 43 are perpendicular to each other to form an L-shaped structure, the hot stamping block 5 is attached to the first side plate 42 and the second side plate 43, and the shaping surface 41 is arranged at one end of the first side plate 42 away from the second side plate 43.

[0050] The shaping block 4 is formed into an L-shaped structure by a first side plate 42 and a second side plate 43 vertically, and the hot stamping block 5 is attached to the first side plate 42 and the second side plate 43, thereby increasing the contact area between the hot stamping block 5 and the shaping block 4. When the hot stamping block 5 is used to directly heat the crease of the adhesive tape, part of the heat can be transferred to the shaping block 4, and the bent part of the adhesive tape is heated and shaped through the shaping surface 41 of the shaping block 4, thereby reducing the rebound of the adhesive tape after shaping.

[0051] Preferably, it also includes a slide 6, a driving member 7 and a slide rail 8, the slide rail 8 is assembled on the base 1, the slide rail 8 extends along the second direction Y, the slide 6 is guided and assembled on the slide rail 8, the driving member 7 is transmission-connected to the slide 6, and the shaping block 4 is fixedly assembled on the slide 6.

In this embodiment, the driving member 7 is a cylinder, and the cylinder is fixedly mounted on the bottom of the base 1.

[0053] Preferably, the sliding seat 6 includes a sliding block 61, a fixed block 62, an adjusting rod 63 and a compression spring 64. The sliding block 61 is slidably assembled on the slide rail 8. The fixed block 62 is fixedly assembled on the sliding block 61. One end of the adjusting rod 63 is assembled on the fixed block 62 and the other end is fixedly connected to the shaping block 4. The compression spring 64 is sleeved on the adjusting rod 63, and the compression spring 64 is press-fitted between the fixed block 62 and the shaping block 4.

[0054] The adjusting rod 63 is inserted through the fixed block 62. By changing the thickness of the gasket on the adjusting rod 63, the elastic force of the compression spring 64 can be overcome to change the distance between the shaping block 4 and the fixed block 62, so as to adjust the distance between the two groups of shaping blocks 4 in the open state, and it can adapt to the bending of adhesive tapes of different sizes.

[0055] Preferably, the floating block 3 includes a backing plate 32 and a spring guide rod 33. The spring guide rod 33 is fixedly assembled on the base 1. The backing plate 32 is assembled at one end of the spring guide rod 33 away from the base 1. A supporting surface 31 is formed on the surface of the backing plate 32 away from the spring guide rod 33.

[0056] The floating block 3 is formed by the backing plate 32 and the spring guide rod 33. The spring guide rod 33 has good stability and a more stable reset elastic force, and can well feedback the pressure of the glue pickup head 2 on the pressing plate, ensuring the clamping force of the supporting surface 31 and the adsorption surface 21 on the adhesive tape.

[0057] Preferably, the bending surface 22 is provided with negative pressure holes 23.

[0058] The bending surface 22 is provided with the same negative pressure holes 23 as the adsorption surface 21. When the shaping surface 41 of the shaping block 4 bends the adhesive tape so that the adhesive tape fits on the bending surface 22, the negative pressure holes 23 on the bending surface 22 can adsorb the adhesive tape through negative pressure, and the bent part of the adhesive tape is adsorbed and fixed on the bending surface 22, so that the angle of the bent adhesive tape is fixed and the rebound of the adhesive tape is reduced.

[0059] The present utility model also provides a preferred embodiment of a production line, including an adhesive tape shaping device. The specific structure of the adhesive tape shaping device is the same as that of the adhesive tape shaping device in any of the above embodiments, and will not be repeated here.

[0060] The working process of the present utility model is as follows: as Figure 6 shown, the driving member 7 drives the two groups of shaping blocks 4 to move away from each other along the second direction Y through the sliding seat 6 and move to the open state. The adsorption surface 21 of the glue pickup head 2 sucks and fixes the blue glue under negative pressure and then moves along the first direction Z. The adhesive tape contacts the floating block 3 and is clamped between the adsorption surface 21 and the supporting surface 31; as Figure 7 shown, the glue pickup head 2 continues to move along the first direction Z and enters between the two groups of shaping blocks 4. At this time, both sides of the adhesive tape contact the shaping blocks 4, and the shaping blocks 4 initially fold the adhesive tape upward; as Figure 8As shown in the figure, the rubber head 2 is moved to the low position, and the driving member 7 drives the shaping block 4 to move to the contracted state. At this time, the crease of the adhesive tape is embedded in the heating groove 51 of the heat conducting block 54. The electric heating rod 55 transfers heat to the heat conducting block 54. The heat conducting block 54 directly heats the crease of the adhesive tape by using the heating groove 51. At the same time, the heat conducting block 54 transfers part of the heat to the shaping block 4, and the shaping block 4 heats the bent part of the adhesive tape to perform hot ironing and shaping on the adhesive tape. Moreover, the negative pressure holes 23 on the bent surface 22 of the rubber head 2 adsorb and fix the adhesive tape. As Figure 9 shown in the figure, after the adhesive tape is hot ironed and shaped, the shaping block 4 moves to the open state along the second direction Y. The rubber head 2 adsorbs and fixes the adhesive tape through the adsorption surface 21 and the negative pressure holes 23 on the bent surface 22 and drives the adhesive tape to move to the high position along the first direction Z, and can drive the adhesive tape to stick to the battery cell.

[0061] In summary, the embodiment of the present utility model provides an adhesive tape shaping device and a production line. Negative pressure holes are arranged on the adsorption surface of the rubber head. The adhesive tape can be transferred by using the negative pressure holes to adsorb the adhesive tape. When the rubber head moves from the high position to the low position in the first direction, the adsorption surface fits with the supporting surface on the floating block, and the adhesive tape is squeezed and fixed between the rubber head and the floating block. The shaping block moves from the open state to the contracted state along the second direction, and the shaping surface fits with the bent surface, and the edge part of the adhesive tape can be bent and fixed between the shaping surface and the bent surface. The adhesive tape is fixed and shaped by using the shaping block, the floating block and the rubber head. A hot ironing block is fixedly assembled on the shaping block. When the shaping block moves to the contracted state, the connection part between the bent surface and the adsorption surface is embedded in the heating groove of the hot ironing block, and the heating groove directly heats the folded corner of the adhesive tape to ensure the shaping effect at the folded corner of the adhesive tape, prevent the adhesive tape from rebounding after being bent, and the adhesive tape can maintain a fixed angle for attachment after cooling, reducing the risk of cracked pole ears after the battery cells are assembled.

[0062] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
