Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tape processing technology, and specifically relates to a tape bending device. Background Technology
[0002] Currently, the automated production of backsheet modules in the photovoltaic industry is still in its nascent stage of development, making automated production particularly important. Solar cells are connected in series and then undergo processes such as stacking, lamination, and encapsulation to form photovoltaic modules. Specifically, multiple solar cells are welded together in series using solder strips to form a cell string. These cell strings are then arranged according to the required photovoltaic module layout and laminated. Busbars are then welded to the ends of the cell strings using solder strips to collect current into a junction box, thus providing power to the outside world. After the busbars are bent, they need to be covered with tape to prevent movement and damage in subsequent processes. Later in the process, this tape needs to be removed, which presents a challenge due to the tape being difficult to remove. Utility Model Content

[0006] When folding the tape, the non-adhesive side of the tape is adsorbed and fixed on the adsorption surface, and the free end of the tape is placed on the first pressure block. The first pressure block and the adsorption platform are close together in the extension direction of the tape until the adsorption surface is below the first pressure block, so that the tape is bent. Then the first pressure block and the adsorption platform are close together in the height direction until the first pressure block presses the bent tape onto the adsorption platform, so that the two opposite adhesive sides of the tape are in contact with each other after bending.
[0007] As a further improvement of this utility model, there is a preset height difference between the side of the first pressing block away from the tape and the adsorption surface in the height direction.
[0008] As a further improvement of this utility model, the folding mechanism includes a second pressing block arranged along the height direction, and the second pressing block is connected to the first pressing block to form an inverted L-shaped structure.

[0010] As a further improvement of this utility model, the cutting mechanism includes a cutting blade clamping block, which fixes the cutting blade on the first clamping block or the second clamping block.
[0011] As a further improvement of this utility model, it includes a first driving mechanism, a second driving mechanism and a third driving mechanism. The first driving mechanism can drive the first pressing block and / or the adsorption table to move in the tape extension direction, the second driving mechanism can drive the first pressing block and / or the adsorption table to move in the height direction, and the third driving mechanism can drive the cutting knife to move to cut the tape.
[0012] As a further improvement of this utility model, the power output end of the first driving mechanism is connected to the adsorption platform, and the first driving mechanism drives the adsorption platform to move in the tape extension direction, so that the adsorption platform moves closer to or further away from the second pressure block.

[0014] As a further improvement of this utility model, the third driving mechanism drives the second driving mechanism to move in the width direction of the tape, so that the cutter moves in the width direction of the tape to cut the tape.
[0015] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.
[0016] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:
[0017] (1) The tape bending device of this utility model includes a folding mechanism and an adsorption platform. The adsorption platform has an adsorption surface. The folding mechanism includes a first pressure block. When folding the tape, the adsorption platform first presses and fixes the non-adhesive side of the tape onto the adsorption surface, and places the free end of the tape on the first pressure block. Then, the first pressure block and the adsorption platform move closer together in the extension direction of the tape, so that the tape is bent. Then, the first pressure block and the adsorption platform move closer together in the height direction, so that the two adhesive sides of the tape are attached to each other after bending, forming a tearing position that is easy to tear off the tape later, effectively solving the problem of difficulty in tearing the tape later.
[0018] (2) The tape bending device of this utility model includes a cutting mechanism, which includes a cutting blade. The cutting blade can cut the tape after it has been pulled out to a preset length, so that the free end of the tape falls on the first pressure block, so that the device can make a tear-off position at the end according to the above process.

[0029] Example:
[0030] Please see Figures 1-3 In a preferred embodiment of this utility model, the tape bending device includes a folding mechanism 1 and an adsorption platform 2. The adsorption platform 2 holds the tape 8 on it tightly. The relative displacement between the folding mechanism 1 and the adsorption platform 2 causes one end of the tape 8 to be folded to form a tear-away position 803. Figure 3 As shown, one side of the tape 8 is the adhesive side 801, and the other side is the non-adhesive side 802. The tear-off position 803 is a small section that can be torn manually, which can effectively solve the problem of difficulty in tearing the tape later.
[0031] like Figure 1 As shown, the adsorption platform 2 has an adsorption surface 201, and the folding mechanism 1 includes a first pressing block 101. The first pressing block 101 and the adsorption platform 2 can be close to or far away in the tape extension direction, and the first pressing block 101 and the adsorption platform 2 can be close to or far away in the height direction.
[0032] In this embodiment, the direction of extension of the tape refers to... Figure 2 The X-direction and the height direction refer to Figure 2 In the Z direction. The approach or distance between the first pressing block 101 and the adsorption stage 2 in the X and / or Z directions can be caused by the movement of the first pressing block 101, the movement of the adsorption stage 2, or the simultaneous movement of the first pressing block 101 and the adsorption stage 2.
[0033] For example, in the X direction, the first pressing block 101 can move back and forth, while the adsorption stage 2 remains stationary; alternatively, in the X direction, the first pressing block 101 remains stationary, while the adsorption stage 2 can move back and forth; or, in the X direction, both the first pressing block 101 and the adsorption stage 2 can move back and forth. The same applies in the Z direction, and will not be described further.
[0034] In actual use, the process of creating the tear-out position by this tape bending device is as follows: the adsorption table 2 adsorbs and fixes the non-adhesive side 802 of the tape 8 onto the adsorption surface 201, and the free end of the tape 8 is placed on the first pressure block 101. The first pressure block 101 and the adsorption table 2 move closer together in the tape extension direction until the adsorption surface 201 is below the first pressure block 101, so that the tape 8 on the first pressure block 101 is bent. Then the first pressure block 101 and the adsorption table 2 move closer together in height until the first pressure block 101 presses the bent tape 8 onto the adsorption table 2, so that the two opposite adhesive sides 801 of the tape after bending stick together to form the tear-out position 803 that is easy to tear off later.
[0035] Preferably, there is a preset height difference in the height direction between the side of the first pressing block 101 facing away from the tape 8 and the adsorption surface 201, so that there is a suitable height gap between the first pressing block 101 and the adsorption surface 201. This makes it easier for the tape to bend when the first pressing block 101 and the adsorption table 2 approach each other in the X direction, and for the adhesive surface 801 to remain in a relative state, so as to avoid the height gap between the two being too large, causing the opposite adhesive surfaces 801 to misalign, resulting in poor subsequent bonding.
[0036] Preferably, the adsorption platform 2 uses vacuum adsorption to adsorb the non-adhesive side 802 of the tape 8 onto the adsorption surface 201, so that the non-adhesive side 802 of the tape 8 and the adsorption surface 201 are tightly attached together, ensuring that the tape 8 will not detach from the adsorption surface 201 when the adsorption platform 2 and the first pressure block 101 move relative to each other.
[0037] In a preferred embodiment, the folding mechanism 1 includes a second pressing block 102 arranged along the height direction. The second pressing block 102 is connected to the first pressing block 101 to form an inverted L-shaped structure to accommodate the adsorption platform 2.
[0038] In this preferred embodiment, when the adsorption stage 2 and the first pressing block 101 approach each other along the X direction, the second pressing block 102 can restrict the adsorption stage 2 to the area below the first pressing block 101, so as to prevent the relative displacement between the adsorption stage 2 and the first pressing block 101 along the X direction from being too large, which would affect the subsequent bonding between the two opposing adhesive surfaces 801.
[0039] Preferably, the second pressing block 102 and the first pressing block 101 can be a single unit or two independent structures. The side of the second pressing block 102 facing the adsorption table 2 and the side of the first pressing block 101 facing away from the tape form an inverted "L" shaped area.
[0040] More preferably, the tape bending device of this utility model further includes a cutting mechanism 3, which includes a cutter 301. When the tape is pulled out to a preset length, the cutter 301 can cut the tape to form a free end.
[0041] In this embodiment, the tape 8 can be pulled out to a preset length by a tape pulling mechanism or manually, so that the tape 8 passes through the adsorption table 2 and the first pressure block 101 in sequence, and then the cutter 301 cuts the tape 8 to form a free end, and the free end falls on the first pressure block 101.
[0042] For example, the tape bending device of this utility model is provided with a tape dispensing device and a tape pulling device on both sides. The tape released by the tape dispensing device passes through the adsorption table 2 and the first pressure block 101 in sequence and is pulled out to a preset length by the tape pulling device. The cutting knife 301 is located on the side of the first pressure block 101 close to the tape pulling device. After the tape 8 is pulled out to a preset length, the cutting knife 301 cuts the tape 8 to form a free end, and the free end falls on the first pressure block 101. Then, the tear-off position 903 is made according to the aforementioned process.
[0043] Preferably, the cutting blade 301 is fixedly connected to the first pressing block 101 or the second pressing block 102, for example, as shown in the example. Figure 1 As shown, the cutter 301 is fixedly connected to the second pressure block 102. For example, the cutter 301 can be glued to the side of the second pressure block 102.
[0044] Preferably, the cutting mechanism 3 includes a cutting blade clamping block 302 for fixing the cutting blade 301 on the first clamping block 101 or the second clamping block 102 to maintain the stability of the cutting blade 301 during cutting.
[0045] More preferably, the tape bending device of this utility model further includes a first driving mechanism 4, a second driving mechanism 5 and a third driving mechanism 6. The first driving mechanism 4 can drive the first pressing block 101 and / or the suction table 2 to move in the tape extension direction. The second driving mechanism 5 can drive the first pressing block 101 and / or the suction table 2 to move in the height direction. The third driving mechanism 6 can drive the cutter 301 to move and cut the tape, so as to realize the actions of cutting the tape 8, folding the tape 8 and pressing the adhesive surface 801, so that the end of the tape 8 forms a tear-off position 903, so that the tape can be easily and quickly torn off later.
[0046] Specifically, the first drive mechanism 4, the second drive mechanism 5, and the third drive mechanism 6 can all be cylinders.
[0047] In a preferred embodiment, the power output end of the first driving mechanism 4 is preferably fixedly connected to the adsorption table 2 to drive the adsorption table 2 to move in the tape extension direction. The power output end of the second driving mechanism 5 is preferably fixedly connected to the first pressure block 101 or the second pressure block 102 to drive the first pressure block 101 or the second pressure block 102 to move in the height direction. When the cutter 301 is not connected to the first pressure block 101 or the second pressure block 102, the power output shaft of the third driving mechanism 6 is preferably connected to the cutter 301 to drive the cutter 301 to move in the tape width direction; when the cutter 301 is fixedly connected to the first pressure block 101 or the second pressure block 102, the power output end of the third driving mechanism 6 is preferably connected to the first driving mechanism 4, and by driving the first driving mechanism 4 as a whole to move in the width direction of the tape 8, the cutter 301 moves in the width direction of the tape to cut the tape 8.
[0048] In this embodiment, the width direction of the tape refers to... Figure 2 In the Y direction, the width direction of the tape is preferably perpendicular to the extension direction of the tape, and the height direction is preferably perpendicular to the plane containing the width direction and the extension direction of the tape.
[0049] More preferably, the first drive mechanism 4, the second drive mechanism 5 and the third drive mechanism 6 are mounted on the mounting plate 7 to ensure the stability of the tape bending device during operation.
[0050] In a preferred embodiment, when the driving of the first driving mechanism 4, the second driving mechanism 5, and the third driving mechanism 6 does not affect each other, the first driving mechanism 4 is mounted and fixed on the mounting plate 7 via the first mounting plate 701, the second driving mechanism 5 is mounted and fixed on the mounting plate 7 via the second mounting plate 702, and the third driving mechanism 6 is mounted and fixed on the mounting plate 7 via the third mounting plate 703.
[0051] In another preferred embodiment, the cutter 301 is fixedly mounted on the first pressure block 101 / second pressure block 102. The adsorption table 2 is connected to the power output shaft of the first drive mechanism 4, and the second pressure block 102 is connected to the power output shaft of the second drive mechanism 5. The first drive mechanism 4 and the second drive mechanism 5 are respectively mounted and fixed on the first mounting plate 701. The first mounting plate 701 is connected to the power output shaft of the third drive mechanism 6, and the third drive mechanism 6 is mounted on the mounting plate 7 via the third mounting plate 703. In this embodiment, the third drive mechanism 6 drives the first mounting plate 701 to move along the Y direction, which in turn drives the folding mechanism 1, the adsorption table 2, and the cutting mechanism 3 above it to move together along the Y direction, so that the cutter 301 cuts the tape 8. Then, the folding mechanism 1 and the adsorption table 2 respectively perform adsorption, folding, and pressing operations on the tape 8 through the second drive mechanism 5 and the first drive mechanism 4, without interfering with each other, making the overall structure compact and reducing the space occupied.
[0052] The tape bending device of this utility model can perform operations such as cutting, adsorption, folding and pressing of tape, quickly cut the tape and automatically fold the end of the tape into a tear-off position. The operation is smooth, highly versatile and has good application prospects and promotion value.
