Description

Technical Field

[0001] This application relates to the field of solar cell module manufacturing technology, and in particular to a film tape splicing device. Background Technology

[0002] Coating and stringing is a crucial step in the manufacturing of solar cell modules. During this process, the film tape is cut into sheets or strips. When heated, these sheets or strips release their adhesive properties, bonding the solder tape to adjacent cells, thus connecting the cells in series to form a cell string. The film tape is released from the roll for supply. When the film tape on the roll is used up, a new roll needs to be replaced, and the ends of the film tape from the two rolls are spliced ​​together for reuse.

[0003] Currently, most membrane tape splicing is done manually, resulting in low splicing efficiency. Utility Model Content

[0004] To address the problems of the prior art, this application provides a film tape splicing device that can automatically splice the film tape of two consecutive rolls together when the film tape on the roll is about to run out.

[0005] Specifically, this application provides a membrane tape splicing device for splicing a first membrane tape and a second membrane tape. The membrane tape splicing device includes: a first fixing mechanism, a second fixing mechanism, and a splicing mechanism.

[0006] The first fixing mechanism is located at the first continuation station and is configured to fix the first film strip; the second fixing mechanism is located at the second continuation station and is configured to fix the second film strip; when the first film strip is the working film strip, the second film strip is the spare film strip; when the second film strip is the working film strip, the first film strip is the spare film strip.

[0007] The splicing mechanism includes a splicing component and a displacement driving component. The splicing component includes a docking component, a heating component, and a cutting component. The splicing component is mated with the displacement driving component, which is used to drive the splicing component to move between a first splicing station and a second splicing station.

[0008] The docking assembly is configured to: cooperate with the first fixing mechanism or the second fixing mechanism to fix the working membrane strip, and after the cutting assembly cuts the working membrane strip, be driven by the displacement driving assembly to overlap the tail of the working membrane strip remaining on the docking assembly with the head of the spare membrane strip fixed on the first fixing mechanism or the second fixing mechanism.

[0009] The cutting component is configured to cut the working membrane strip fixed between the docking component and the first fixing mechanism or the second fixing mechanism;

[0010] The heating component is configured to heat the overlap between the tail of the working film belt and the head of the spare film belt to bond the working film belt and the spare film belt together.

[0011] This application provides a film tape splicing device for splicing a first film tape and a second film tape. When the first film tape is a working film tape, the second film tape is a spare film tape; when the second film tape is a working film tape, the first film tape is a spare film tape. A first fixing mechanism is set at a first splicing station to fix the first film tape, and a second fixing mechanism is set at a second splicing station to fix the second film tape. When the working film tape is about to run out, a displacement driving component drives the splicing component to move between the first fixing mechanism and the second fixing mechanism, so that the docking component in the splicing component cooperates with the first fixing mechanism or the second fixing mechanism where the working film tape is located to fix the working film tape. After the cutting component cuts the working film tape, the displacement driving component drives the splicing component to move again, so that the tail of the working film tape remaining on the docking component overlaps with the head of the spare film tape fixed on the first fixing mechanism or the second fixing mechanism. The heating component in the splicing component heats the overlap. It can automatically complete the splicing of the working film tape and the spare film tape when the working film tape is about to run out, improve the splicing speed of the film tape roll, and improve the production efficiency of solar cell module coating and stringing.

[0012] In some embodiments, both the first membrane strip and the second membrane strip are conveyed along a first direction;

[0013] When the splicing component moves to the first splicing station, the first fixing mechanism, the cutting component, the heating component, and the docking component are arranged sequentially along the first direction;

[0014] When the splicing assembly moves to the second splicing station, the second fixing mechanism, the cutting assembly, the heating assembly, and the docking assembly are arranged sequentially along the first direction;

[0015] The first fixing mechanism and the second fixing mechanism are arranged at intervals along a second direction perpendicular to the first direction;

[0016] The displacement drive component is configured to drive the continuation component to move along a first direction and a second direction.

[0017] When the connecting assembly cooperates with the first fixing mechanism, the first fixing mechanism, the cutting assembly, the heating assembly, and the docking assembly are arranged along the conveying direction of the first film belt and the second film belt. When the connecting assembly cooperates with the second fixing mechanism, the second fixing mechanism, the cutting assembly, the heating assembly, and the docking assembly are arranged along the conveying direction of the first film belt and the second film belt. This allows for the sequential execution of the docking assembly fixing the working film belt, the cutting assembly cutting the working film belt located between the docking assembly and the first or second fixing mechanism, and the heating assembly heating the overlap between the working film belt and the spare film belt.

[0018] In some embodiments, the docking assembly includes a first platform, a first pressure block, and a first driving member;

[0019] The fixed end of the first driving member is fixed to the driving end of the displacement driving assembly. One of the first platform and the first pressure block is fixed to the driving end of the displacement driving assembly, and the other is engaged with the driving end of the first driving member. The first driving member is used to drive the first platform and the first pressure block to move relative to each other to clamp and fix the working film belt.

[0020] The docking assembly uses a first platform and a first pressure block to clamp and fix the working membrane belt, which can stably clamp and fix the working membrane belt and prevent the working membrane belt from shifting during cutting and splicing.

[0021] In some embodiments, the membrane tape splicing device further includes a first receiving portion and a second receiving portion, wherein:

[0022] The first receiving part is fixedly disposed on the side of the first fixing mechanism to support the first film strip, and a gap is left between the first receiving part and the first fixing mechanism for the cutting component to cut.

[0023] The second receiving part is fixedly installed on the side of the second fixing mechanism to support the second film strip. A gap is left between the second receiving part and the second fixing mechanism for the cutting component to cut.

[0024] The bottom of the first pressing block has a first pressing part and a second pressing part. The second pressing part is located at one end of the first pressing part adjacent to the heating component and extends toward the heating component. The first pressing part is used to cooperate with the first platform to clamp and fix the working film belt. The second pressing part is used to cooperate with the first receiving part or the second receiving part to clamp and fix the working film belt or the overlap between the working film belt and the spare film belt.

[0025] The heating component is used to heat the overlap between the working film strip and the spare film strip through the second pressing part.

[0026] By providing a first receiving part supporting the first film strip on the side of the first fixing mechanism and a second receiving part supporting the second film strip on the side of the second fixing mechanism, the pressure-bearing area of ​​the first film strip and the second film strip can be increased, and the first film strip and the second film strip can be better fixed. The heating component passes through the second pressing part to heat the overlap between the working film strip and the spare film strip, which can increase the contact area of ​​the first pressing block with the film strip and reduce the gap between the first pressing block and the first fixing mechanism or the second fixing mechanism after pressing, making it easier for the cutting component to cut the working film strip more smoothly.

[0027] In some embodiments, the bearing surfaces of both the first receiving portion and the second receiving portion are covered with heat insulation pads.

[0028] By covering the bearing surfaces of the first and second receiving parts with heat insulation pads, the heat from the heating component can be concentrated at the overlap between the working film belt and the spare film belt, improving the heat bonding effect between the working film belt and the spare film belt, while avoiding adverse thermal effects of the heat from the heating component on the first and second receiving parts.

[0029] In some embodiments, a flexible layer is provided at the bottom of the first pressing block; and / or,

[0030] The bearing surface of the first platform is covered with a heat insulation pad.

[0031] By providing a flexible layer at the bottom of the first pressing block, it can be ensured that the first pressing block and the first platform effectively press the working film belt together. Covering the bearing surface of the first platform with a heat insulation pad can prevent the heating component from having a thermal impact on other mechanisms.

[0032] In some embodiments, the membrane tape splicing device further includes a support, and the first fixing mechanism includes a second platform, a second pressure block and a second driving member;

[0033] The fixed end of the second driving member is fixed to the bracket. One of the second platform and the second pressure block is fixed to the bracket, and the other is connected to the driving end of the second driving member. The second driving member is used to drive the second platform and the second pressure block to move relative to each other to clamp and fix the first film strip or reset it.

[0034] The second fixing mechanism includes a third platform, a third pressure block, and a third driving member. The fixed end of the third driving member is fixed to the bracket. One of the third platform and the third pressure block is fixed to the bracket, and the other is connected to the driving end of the third driving member. The third driving member is used to drive the third platform and the third pressure block to move relative to each other to clamp and fix the second membrane strip or reset it.

[0035] The first fixing mechanism clamps and fixes the first film strip by cooperating with the second platform and the second pressure block, and the second fixing mechanism fixes the second film strip by cooperating with the third platform and the third pressure block. This can firmly fix the first film strip and the second film strip and prevent the first film strip and the second film strip from shifting during cutting and splicing.

[0036] In some embodiments, a flexible layer is provided at the bottom of the second pressure block; and / or, a heat insulation pad is provided on the bearing surface of the second platform.

[0037] The bottom of the third pressing block is provided with a flexible layer; and / or, the bearing surface of the third platform is covered with a heat insulation pad.

[0038] The first fixing mechanism, by providing a flexible layer at the bottom of the second pressing block and / or providing a heat insulation pad on the bearing surface of the second stage, can ensure that the second pressing block and the second stage effectively press the first film strip together, thus avoiding the thermal impact on the second stage when the heating component heats it up. The second fixing mechanism, by providing a flexible layer at the bottom of the third pressing block and / or providing a heat insulation pad on the bearing surface of the third stage, can ensure that the third pressing block and the third stage effectively press the second film strip together, and avoid the thermal impact on the third stage when the heating component heats it up.

[0039] In some embodiments, the cutting assembly includes a fourth driving member and a scribing blade, the fixed end of the fourth driving member is connected to the driving end of the displacement driving assembly, and the driving end of the fourth driving member is mated with the scribing blade.

[0040] The fourth drive unit is configured to drive the scribing blade to move along the width direction of the working film strip to cut the working film strip.

[0041] The working film belt is cut by moving the scriber along the width direction of the working film belt through the fourth driving component. It can smoothly cut the working film belt between the first fixing mechanism or the second fixing mechanism and the docking assembly. It has a simple structure and low cost.

[0042] In some embodiments, the heating assembly includes a fifth driving member and a heating member, the fixed end of the fifth driving member is connected to the driving end of the displacement driving assembly, the driving end of the fifth driving member is mated with the heating member, and the heating member is configured to heat the overlap between the working film strip and the spare film strip by being driven by the fifth driving member.

[0043] When the heating element contacts the overlap between the heating working film belt and the spare film belt, a flexible layer is provided at the bottom of the heating element.

[0044] By setting a flexible layer at the bottom of the heating element, it is possible to effectively press the overlap between the working film belt and the spare film belt when the heating element is over-pressurized, thus ensuring the heating and bonding effect. Attached Figure Description

[0053] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0054] As described in the background section, the film strip is released from the feed roll for feeding. When the film strip on the feed roll is used up, a new feed roll needs to be replaced, and the ends of the film strips from the two feed rolls need to be spliced ​​together for reuse. Currently, film strip splicing is done manually, which is inefficient.

[0055] To address the aforementioned issues, this application creatively proposes a film tape splicing device for splicing a first film tape and a second film tape. When the first film tape is a working film tape, the second film tape is a spare film tape; conversely, when the second film tape is a working film tape, the first film tape is a spare film tape. A first fixing mechanism is set at a first splicing station to fix the first film tape, and a second fixing mechanism is set at a second splicing station to fix the second film tape. When the working film tape is about to run out, a displacement driving component drives the splicing component to move between the first and second fixing mechanisms, so that the docking component in the splicing component cooperates with the first or second fixing mechanism where the working film tape is located to fix the working film tape. After the cutting component cuts the working film tape, the displacement driving component drives the splicing component to move again, overlapping the tail of the working film tape remaining on the docking component with the head of the spare film tape fixed on the first or second fixing mechanism. The heating component in the splicing component heats the overlap. This device can automatically complete the splicing of the working film tape and the spare film tape when the working film tape is about to run out, improving the splicing speed of the film tape rolls and increasing the production efficiency of solar cell module coating and stringing.

[0056] The present application will be described in detail below through specific embodiments.

[0057] This application provides a membrane tape splicing device, which is described in an embodiment. Figure 1 As shown, the membrane tape splicing device is used to splice the first membrane tape 1 and the second membrane tape 2. The membrane tape splicing device includes: a first fixing mechanism 3, a second fixing mechanism 4 and a splicing mechanism 5.

[0058] The first fixing mechanism 3 is located at the first continuation station M and is configured to fix the first film strip 1. The second fixing mechanism 4 is located at the second continuation station N and is configured to fix the second film strip 2. When the first film strip 1 is the working film strip, the second film strip 2 is the spare film strip. When the second film strip 2 is the working film strip, the first film strip 1 is the spare film strip.

[0059] The continuing mechanism 5 includes a continuing component and a displacement driving component 51. The continuing component includes a docking component 52, a heating component 53 and a cutting component 54. The continuing component is mated with the displacement driving component 51.

When the first membrane tape 1 is a working membrane tape, the second membrane tape 2 is a spare membrane tape; when the second membrane tape 2 is a working membrane tape, the first membrane tape 1 is a spare membrane tape. A first fixing mechanism 3 is set at a first splicing station M to fix the first membrane tape 1, and a second fixing mechanism 4 is set at a second splicing station N to fix the second membrane tape 2. When the working membrane tape is about to run out, a displacement driving component 51 drives the splicing component to move between the first fixing mechanism 3 and the second fixing mechanism 4, so that the docking component 52 in the splicing component connects with the working membrane. The first fixing mechanism 3 or the second fixing mechanism 4, where the working film tape is located, cooperates to fix the working film tape. After the cutting component 54 cuts the working film tape, the displacement driving component 51 drives the continuing component to move, so that the tail of the working film tape remaining on the docking component 52 overlaps with the head of the spare film tape fixed on the first fixing mechanism 3 or the second fixing mechanism 4. The heating component 53 in the continuing component heats the overlap, which can automatically complete the continuation of the working film tape and the spare film tape when the working film tape is about to be used up, improve the continuation speed of the film tape roll, and improve the production efficiency of solar cell module coating stringing.

When the connecting component cooperates with the second fixing mechanism 4, the second fixing mechanism 4, the cutting component 54, the heating component 53, and the docking component 52 are arranged along the conveying direction of the first membrane belt 1 and the second membrane belt 2. The docking component 52 can sequentially fix the working membrane belt, the cutting component 54 can cut the working membrane belt located between the docking component 52 and the first fixing mechanism 3 or the second fixing mechanism 4, and the heating component 53 can heat the overlap between the working membrane belt and the spare membrane belt.

[0070] Optionally, the displacement drive assembly 51 includes a translation drive and a lifting drive. The translation drive is connected to the drive end of the lifting drive, and the connecting assembly is connected to the drive end of the translation drive. The translation drive is used to drive the connecting assembly to translate along a first direction, and the lifting drive is used to drive the connecting assembly to move up and down along a second direction. The translation drive and the lifting drive can be any existing linear drive, such as a cylinder, a lead screw motor, etc.

One of the first platform 521 and the first pressure block 522 is fixed to the driving end of the displacement driving assembly 51, and the other is engaged with the driving end of the first driving member 523. The first driving member 523 is used to drive the first platform 521 and the first pressure block 522 to move relative to each other to clamp and fix the working film belt.

[0073] The docking assembly 52 uses a first platform 521 and a first pressure block 522 to clamp and fix the working film belt, which can stably clamp and fix the working film belt and prevent the working film belt from shifting during cutting and splicing. The first driving component 523 can be a linear motor, a cylinder, or any other structure or device that can drive the first pressure block 522 or the first platform 521 to rise and fall, and this application does not limit it.

The toothed second pressing part 52B extending towards the heating assembly 53 at the bottom of the first pressing block 522, together with the first clearance groove 531 at the bottom of the heating assembly 53, can increase the contact area of ​​the first pressing block 522 with the film strip, reduce the gap between the first pressing block 522 and the first fixing mechanism 3 or the second fixing mechanism 4 after pressing, and facilitate the cutting assembly to cut the working film strip more smoothly.

This allows the working film to be cut smoothly between the first fixing mechanism 3 or the second fixing mechanism 4 and the docking assembly 52. ​​The structure is simple and the cost is low.

[0095] Optionally, the cutting assembly 54 can also drive the cutter to rise and fall via the fourth driving member 541, with a gap 8 between the first receiving part 6 and the first fixing mechanism 3 for the cutting assembly to cut the working film strip. Alternatively, the fourth driving member 541 can drive the strip soldering iron to rise and fall or move along the width direction of the working film strip, with the gap 8 between the first receiving part 6 and the first fixing mechanism 3 for the cutting assembly to cut the working film strip to melt it.

[0096] In some examples, continue to refer to Figure 6 As shown, the cutting assembly 54 also includes a fixing frame 543 and a guide rail 544, and the fixing frame 543 is connected to the drive end of the displacement driving assembly 51.

[0097] The fixed end of the fourth driving component 541 is fixed on the fixed frame 543. The guide rail 544 is installed on the fixed frame 543 along the width direction of the working film belt, that is, the guide rail 544 is set along the third direction, which is perpendicular to the first direction and the second direction. The scribing blade 542 is slidably connected to the guide rail 544.

[0098] The fourth driving component 541 may be a linear motor, a cylinder, or other component or device that can be coupled with the scribing blade 542 to drive the scribing blade 542 to move along the width direction of the working film belt.

[0099] In some embodiments, the heating assembly 53 includes a fifth driving member 532 and a heating member 533. The fixed end of the fifth driving member 532 is connected to the driving end of the displacement driving assembly 51, and the driving end of the fifth driving member 532 is mated with the heating member 533. The heating member 533 is configured to heat the overlap between the working film belt and the spare film belt by being driven by the fifth driving member 532.

[0100] When the heating element 533 contacts the overlap between the heating working film belt and the spare film belt, a flexible layer 9 is provided at the bottom of the heating element 533.

[0101] Optionally, the heating element 533 can be any heating element that can heat the first membrane strip 1 and the second membrane strip 2, such as a heating plate with an internal heating rod, a heating plate with a heating pad at the bottom, an ultrasonic heating element, an electric heating box, or a heating lamp box, and thermally bond the tail of the working membrane strip to the head of the spare membrane strip at the overlap.

[0102] When the heating element 533 heats the overlap between the tail of the working film belt and the head of the spare film belt by means of contact heating (such as the heating plate of the internal heating rod or the heating plate with the heating pad at the bottom), by setting a flexible layer 9 at the bottom of the heating element 533, the overlap between the working film belt and the spare film belt can be effectively pressed when the heating element 533 is over-pressurized, so as to ensure the heating and bonding effect.

[0103] The fifth driving component 532 may be a linear motor, a cylinder, or other component or device that can be connected to the heating component 533 to drive the heating component 533 to rise and fall.
