TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic module production, in particular to a tape pulling and attaching device for photovoltaic modules. BACKGROUND

[0002] The foam tape is made of EVA or PE foam as a base material, coated with solvent type (or hot melt type) pressure sensitive adhesive on one or both sides, and then covered with release paper. It has the functions of sealing and shock absorption. It has excellent sealing performance, compression resistance, flame resistance, and infiltration. It is widely used in electronic products, mechanical parts, various small household appliances, mobile phone accessories, industrial instruments, computers and peripheral equipment, automobile accessories, audio-visual equipment, toys, cosmetics, etc.

[0003] At present, the foam tape used for attaching photovoltaic modules is mostly wound for storage. When attaching, the tape needs to be pulled out and the release paper needs to be torn off before being attached to the surface of the photovoltaic module. However, after long-term winding storage, the curvature of the tape is affected by winding, and the flatness is low when attaching, which is easy to deviate. SUMMARY

[0004] To achieve the above purpose, the present application is realized by the following technical scheme: a tape pulling and attaching device for photovoltaic modules, comprising a cabinet, a control rod is fixedly connected to the outer surface edge of the cabinet, a connecting frame is fixedly connected to the surface of the cabinet away from the control rod, a lifting rod is rotatably connected to the surface of the connecting frame, an extension frame is fixedly connected to the lower surface of the connecting frame, two extension frames are provided, a sleeve rod is fixedly connected between the opposite surfaces of the two extension frames, and a limiting rod is sleeved on the middle of the outer surface of the sleeve rod; the staff sets two rolls of tape on the surface of the sleeve rod, the limiting rod limits the two rolls of tape between the limiting rod and the extension frame, a motor is installed in the cabinet, the output end of the motor is connected with a pulling and rotating assembly, and the motor drives the pulling and rotating assembly to rotate when rotating.

[0005] The tape pulling and attaching device for photovoltaic modules further comprises:

[0006] The pulling and rotating assembly is fixedly connected to the outer surface of the cabinet, the pulling and rotating assembly comprises a shaft seat, the lower surface of the shaft seat is fixedly connected with a base, the upper surface of the base is fixedly connected with a spring supporting assembly on both sides, the outer surface of the base is provided with a sliding groove on both sides, and the surface of the sliding groove is provided with a sliding groove; the staff passes the tape between the spring supporting assembly and the friction shaft, at this time the motor in the cabinet drives the friction shaft to rotate, the tape is conveyed to the pressing plate, the photovoltaic module is placed on the surface of the pressing plate, the release paper on one side of the double-glass tape pulled out is torn off, and the tape is attached to the surface of the photovoltaic module.

[0007] The cutting and pressing assembly is rotationally connected to the inner surface of the collecting seat, and the surface of the cutting and pressing assembly is fixedly connected with a pressing plate. The cutting and pressing assembly comprises fixed ring plates, and two fixed ring plates are symmetrically arranged on the surface of the pressing plate. The staff places the photovoltaic module on the surface of the pressing plate. The pressing plate is affected by gravity and falls down, and the connecting rods on both sides are driven to rotate downward on the surface of the rotating rod. At this time, the short shaft is affected by the connecting rods and drives the rotating plate and the sliding cutting frame to rotate, and friction is generated between the surface of the rotating plate and the surface of the friction shaft. The adhesive tape is cut.

[0008] Preferably, the elastic supporting assembly is fixedly connected to the outer surface of the base, and the elastic supporting assembly is provided with two elastic supporting assemblies which are symmetrically arranged around the shaft seat. The elastic supporting assembly comprises a screw rod, a limiting block is threadedly connected to the surface of the screw rod, a fixed table is fixedly connected to the surface of the limiting block, and a supporting frame is fixedly connected to the surface of the fixed table. The foam tape is made of EVA or PE foam as a base material, which is coated with solvent type (or hot melt type) pressure sensitive adhesive on one side or both sides and then is coated with release paper. The tape is usually stored in a winding manner. The tape passes between the elastic supporting assembly and the friction shaft. Since the elastic supporting assembly and the friction shaft are staggered, the tape is attached to the elastic supporting assembly and is in contact with the friction shaft. When the tape is pulled out, it is attached to the surface of the supporting frame and presses the supporting frame, so that the supporting frame stretches the tape between the fixed disc and the shaft seat and shapes the bent tape.

[0009] Preferably, the supporting frame comprises a curved arc plate, a friction rod is fixedly connected to the lower surface of the curved arc plate, a sliding block is slidably connected to the outer surface of the friction rod, a spring rod is fixedly connected to the surface of the sliding block, and a curved arc rod is fixedly connected to the outer surface of the spring rod. The spring rod is made of elastic material and is bent downward after being pressed. When the spring rod is bent, the sliding block at the upper end is clamped between the curved arc rods to maintain the stability of the tape passing through the curved arc plate. After the tape is pulled and conveyed, the pressure on the spring rod disappears, driving the curved arc plate to reset.

[0010] When the tape is pulled, the curved arc plate is pressed, the friction rod slides on the surface of the sliding block, and the spring rod is pressed downward to be attached to the surface of the curved arc rod, supporting the tape during the pulling process. Because the bending radius of the tape is different when it is wound, the bending radius of the tape is small in the initial stage of use, and the surface of the tape is relatively flat. During the pulling process, the tape is easily straightened and attached to the surface of the photovoltaic module. The staff rotates the screw rod to move the fixed table away from the side of the side supporting block, so that the bending angle of the curved arc rod becomes gentle. When the curved arc plate is pressed and attached to the curved arc rod due to the tension of the tape, the upward supporting force on the tape is small, avoiding excessive upward supporting of the relatively flat tape and causing the tape to wrinkle in the opposite direction.

[0011] Preferably, the two arc bending rods are symmetrically arranged with the elastic rod as the center, the outer surface of the arc bending rod is fixedly connected with a side supporting block, the opposite surface of the arc bending rod is fixedly connected with an insertion piece, the surface of the arc bending rod away from the side supporting block is fixedly connected with a close contact block, and the close contact block is fixedly connected to the surface of the fixed table. The insertion piece is arranged between the two arc bending rods, and the insertion piece is supported between the two arc bending rods when the arc bending plate is pressed down. The pressure on the two arc bending rods is prevented from being uneven, the stability of the adhesive tape conveying is affected, and the adhesive tape is prevented from deviating during attachment.

[0012] Preferably, the upper surface of the shaft seat is fixedly connected with a fixed shaft, the outer surface of the fixed shaft is rotatably connected with a friction shaft on both sides, and the outer surface of the friction shaft is fixedly connected with a collection seat on both sides. In the later stage of use of the adhesive tape, due to a large bending arc caused by winding, wrinkles are generated on the surface of the adhesive tape, and in the process of pulling, the adhesive tape is not easy to attach to the surface of the photovoltaic module due to the influence of the wrinkles. The worker rotates the screw rod, the screw rod drives the fixed table to move towards the side supporting block, the bending angle of the arc bending rod is increased, the position of the arc bending plate when being attached to the arc bending rod is higher, the upward supporting force of the arc bending plate is increased, the adhesive tape is shaped between the arc bending plate and the friction shaft when the adhesive tape passes between the arc bending plate and the friction shaft, and the generation of wrinkles is reduced when the adhesive tape is attached.

[0013] Preferably, the collection seat comprises a fixed circular plate, the outer surface of the fixed circular plate is fixedly connected with a sleeve ring, the outer surface of the sleeve ring is fixedly connected with an extension plate on both sides, the surface of the extension plate is fixedly connected with an inclined piece, the surface of the inclined piece is fixedly connected with an extension plate, and the inner surface of the extension plate is fixedly connected with an inner inclined bending piece. When the adhesive tape passes between the friction shaft and the arc bending plate, due to the fact that the surface of the arc bending plate is connected with the friction rod, the adhesive tape is rubbed between the arc bending plate when the adhesive tape is pulled tight, dust attached to the surface of the adhesive tape is bounced off, and the dust slides along the inner inclined bending piece to the surface of the slide groove. Since the slide groove is arranged to be inclined, the dust bounced off from the surface of the adhesive tape is conveniently collected into the slide groove.

[0014] Preferably, the outer surface of the fixed ring plate is fixedly connected with a rotating rod, the surface of the rotating rod is rotatably connected with a connecting rod, the inner surface of the connecting rod is penetrated by a short shaft, the surface of the short shaft is fixedly connected with a rotating piece, and the surface of the rotating piece is fixedly connected with a slide cutting frame. The worker places the photovoltaic module on the pressing plate, and then attaches the adhesive tape pulled out to the surface of the photovoltaic module. Since the position between the elastic pad and the friction shaft is close when the pressing plate is lowered under the pressure, the worker presses the two pressing blocks downward after the attachment is completed, the pressing blocks slide on the surface of the elastic pad, and the adhesive tape is pressed to make the adhesive tape more closely attached to the photovoltaic module.

[0015] Preferably, the sliding cutting frame comprises a circular arc plate, a groove plate is fixedly connected to the surface of the circular arc plate, and a side scraping groove is formed in the surface of the groove plate.

[0016] Preferably, an elastic pad is rotatably connected to the outer surface of the circular arc plate, an insertion block is fixedly connected to the surface of the elastic pad, a cutting piece is fixedly connected to the surface of the insertion block, and a pressing block is slidably connected to the outer surface of the elastic pad.

The tape pulling and attaching device for the photovoltaic module uses double glass tape for edge sealing, the double glass tape is made of improved acrylic pressure-sensitive adhesive with two sides coated with glue, and white anti-sticking paper treated with organic silicon is used as the isolation paper. The tape is usually wound for storage, and the tape passes between the elastic supporting assembly and the friction shaft. Since the elastic supporting assembly and the friction shaft are staggered, the tape is attached to the elastic supporting assembly and in contact with the friction shaft. When the tape is pulled out, it is attached to the surface of the supporting frame and presses the supporting frame, so that the supporting frame pulls and supports the tape between the fixed circular plate and the shaft seat, and shapes the bent tape.

[0019] II. The tape pulling and attaching device for the photovoltaic module presses the bending plate when the tape is pulled, the friction rod slides on the surface of the sliding block under the pressure, and the elastic rod is pressed downward and attached to the surface of the bending rod. During the pulling of the tape, the tape is supported. Since the bending radius of the tape is different when it is wound, the bending radius of the tape is small in the initial stage of use, and the surface of the tape is relatively flat. During the pulling and attaching process, the tape is easily straightened and attached to the surface of the photovoltaic module. The worker rotates the screw, moves the fixed table away from the side supporting block, and makes the bending angle of the bending rod gentle. At this time, when the bending plate is pressed and attached to the bending rod under the pressure generated by the tension of the tape, the upward supporting force of the tape is small, so that the tape is not excessively supported and is not wrinkled in the opposite direction.

[0020] III. The tape pulling and attaching device for photovoltaic modules, through the large bending radius generated by winding in the later stage of tape use, wrinkles are generated on the surface of the tape, in the process of pulling, the photovoltaic module surface is not easy to attach due to the influence of wrinkles, the worker rotates the screw rod, the screw rod drives the fixed table to move to the side close to the side support block, the bending angle of the bending rod is increased, at this time, the position of the bending plate when being attached to the bending rod is higher, the upward tape supporting force is increased, when the tape passes between the bending plate and the friction shaft, the tape is shaped by the bending plate and the friction shaft, and the generation of wrinkles is reduced when the tape is attached.

[0021] IV.

[0022] V. The tape pulling and attaching device for photovoltaic modules, the worker presses the pressing block downward, the pressing block drives the inserted block to rotate, and the cutting piece contacts the tape when rotating to cut the tape, which is convenient for the worker to cut off the tape after attaching.

When the adhesive tape passes between the friction shaft 32 and the bending plate 641, the surface of the bending plate 641 is connected with the friction rod 645, friction is generated between the adhesive tape and the bending plate 641 when the adhesive tape is pulled tight, the dust attached to the surface of the adhesive tape is bounced off, and slides along the inner inclined bending piece 336 to the surface of the sliding channel 36. Since the sliding channel 36 is inclined, the dust bounced off from the surface of the adhesive tape is conveniently collected into the sliding groove 35.

[0038] As shown in the second embodiment, Figures 5-6 The spring supporting assembly 6 is fixedly connected to the outer surface of the base 37, and the spring supporting assembly 6 is provided with two, the two spring supporting assemblies 6 are symmetrically arranged with the shaft seat 34 as the center, the spring supporting assembly 6 comprises a screw rod 62, the surface of the screw rod 62 is threadedly connected with a limiting block 63, the surface of the limiting block 63 is fixedly connected with a fixed table 61, and the surface of the fixed table 61 is fixedly connected with a tape supporting frame 64. The foam adhesive tape is made of EVA or PE foam as a base material, one side or both sides are coated with solvent type (or hot melt type) pressure sensitive adhesive, and then are coated with release paper. The adhesive tape is usually wound and stored, and passes between the spring supporting assembly 6 and the friction shaft 32. Since the spring supporting assembly 6 and the friction shaft 32 are staggered, the adhesive tape is attached to the spring supporting assembly 6 at the same time and contacts the friction shaft 32. When the adhesive tape is pulled out, the adhesive tape is attached to the surface of the tape supporting frame 64 and extrudes the tape supporting frame 64, so that the tape supporting frame 64 pulls and supports the adhesive tape between the fixed circular plate 331 and the shaft seat 34, and shapes the bent adhesive tape.

[0039] The supporting frame 64 comprises a curved plate 641, the lower surface of the curved plate 641 is fixedly connected with a friction rod 645, the outer surface of the friction rod 645 is slidably connected with a sliding block 646, the surface of the sliding block 646 is fixedly connected with an elastic rod 647, and the outer surface of the elastic rod 647 is fixedly connected with a curved rod 643.

[0040] When the adhesive tape is extruded, the friction rod 645 is extruded and slides on the surface of the sliding block 646, and the elastic rod 647 is pressed downward and is combined with the surface of the curved rod 643, so that the adhesive tape is supported during the process of pulling the adhesive tape; because the bending radius generated during winding of the adhesive tape is different, the bending radius generated during winding is small in the initial stage of use of the adhesive tape, the surface of the adhesive tape is relatively flat, and the adhesive tape is easily straightened and attached to the surface of the photovoltaic module during the process of being pulled, the staff rotates the screw rod 62, the screw rod 62 drives the fixed table 61 to move to the side away from the side support block 648, the bending angle of the curved rod 643 becomes gentle, the pressing force of the curved plate 641 combined with the curved rod 643 is small when being pressed downward, the adhesive tape is prevented from being excessively supported and being wrinkled in the opposite direction.

[0041] The curved rod 643 is provided with two curved rods 643 which are symmetrically arranged around the elastic rod 647, the outer surface of the curved rod 643 is fixedly connected with the side support block 648, the opposite surfaces of the curved rod 643 are fixedly connected with the insert piece 642, and the surface of the curved rod 643 away from the side support block 648 is fixedly connected with the abutting block 644.

The insert piece 642 is arranged between the two curved rods 643, and the insert piece 642 is supported between the two curved rods 643 when the curved plate 641 is pressed downward. The pressure on the two curved rods 643 is prevented from being uneven, the stability of the adhesive tape is prevented from being affected, and the adhesive tape is prevented from being deviated during attachment.

[0042] In the late stage of use of the adhesive tape, because the bending radius generated during winding is large, the surface of the adhesive tape is wrinkled, the adhesive tape is not easy to be attached to the surface of the photovoltaic module during the process of being pulled, the staff rotates the screw rod 62, the screw rod 62 drives the fixed table 61 to move to the side close to the side support block 648, the bending angle of the curved rod 643 is increased, the position of the curved plate 641 combined with the curved rod 643 is higher, the supporting force of the adhesive tape is increased, the adhesive tape is shaped by the curved plate 641 and the friction shaft 32 when passing through between the curved plate 641 and the friction shaft 32, and the generation of wrinkles of the adhesive tape is reduced during attachment.

[0043] The third embodiment is as follows,Figures 7-8 As shown, the cutting and pressing assembly 5 is rotationally connected to the inner surface of the collecting seat 33, the surface of the cutting and pressing assembly 5 is fixedly connected with the pressing plate 4, the cutting and pressing assembly 5 comprises the fixed ring plate 56, the fixed ring plate 56 is provided with two, and the two fixed ring plates 56 are symmetrically distributed on the surface of the pressing plate 4. The staff places the photovoltaic module on the surface of the pressing plate 4, the pressing plate 4 is affected by gravity to fall down, and the connecting rod 54 on the two sides is driven to rotate downward on the surface of the rotating rod 55, at this time, the short shaft 52 is affected by the connecting rod 54 to drive the rotating plate 53 and the sliding cutting frame 51 to rotate, and friction is generated with the surface of the friction shaft 32, so that the adhesive tape is cut.

[0044] The outer surface of the fixed ring plate 56 is fixedly connected with the rotating rod 55, the surface of the rotating rod 55 is rotationally connected with the connecting rod 54, the inner surface of the connecting rod 54 penetrates the short shaft 52, and the surface of the short shaft 52 is fixedly connected with the rotating plate 53, and the surface of the rotating plate 53 is fixedly connected with the sliding cutting frame 51. The staff places the photovoltaic module on the surface of the pressing plate 4, and then attaches the adhesive tape pulled out to the surface of the photovoltaic module. Since the pressing plate 4 falls down under the pressure, the position between the elastic pad 514 and the friction shaft 32 is narrowed, when the attachment is completed, the staff presses the two pressing blocks 517 downward, so that the pressing blocks 517 slide on the surface of the elastic pad 514, and press the torn adhesive tape, so that the adhesive tape can be more closely attached to the photovoltaic module.

[0045] The sliding cutting frame 51 comprises the circular arc plate 511, the surface of the circular arc plate 511 is fixedly connected with the groove plate 512, and the surface of the groove plate 512 is provided with the side scraping groove 513. The circular arc plate 511 is arranged at the side of the friction shaft 32, and the side scraping groove 513 is used for grinding the edge of the adhesive tape, so that the flatness of the adhesive tape is improved.

[0046] The outer surface of the circular arc plate 511 is rotationally connected with the elastic pad 514, the surface of the elastic pad 514 is fixedly connected with the insertion block 515, the surface of the insertion block 515 is fixedly connected with the cutting piece 516, and the outer surface of the elastic pad 514 is slidingly connected with the pressing block 517. The staff presses the pressing block 517 downward, so that the pressing block 517 drives the insertion block 515 to rotate, and the cutting piece 516 is in contact with the adhesive tape during rotation, so that the adhesive tape is cut, and the staff can cut the adhesive tape after the attachment is completed.

[0047] In use, the staff sets two rolls of adhesive tapes on the surface of the sleeve rod 8, the limiting rod 7 limits the two rolls of adhesive tapes between the limiting rod 7 and the extension frame 9, the machine box 10 is provided with a motor, the output end of the motor is connected with the pulling and rotating assembly 3, and the motor drives the pulling and rotating assembly 3 to rotate when rotating.

[0048] The staff passes the adhesive tape between the elastic support assembly 6 and the friction shaft 32, at this time the motor in the cabinet 10 rotates to drive the friction shaft 32 to rotate, the adhesive tape is transported to the pressing plate 4, the photovoltaic assembly is placed on the surface of the pressing plate 4, the isolation paper on one side of the adhesive tape pulled out is torn, and the adhesive tape is attached to the surface of the photovoltaic assembly.

[0049] In the later stage of the use of the adhesive tape, due to the large bending radius generated by winding, wrinkles are generated on the surface of the adhesive tape, and in the process of pulling, the adhesive tape is not easy to attach to the surface of the photovoltaic assembly due to the influence of the wrinkles. The staff rotates the screw rod 62, so that the screw rod 62 drives the fixed table 61 to move to the side close to the side support block 648, so that the bending angle of the bending rod 643 is increased. At this time, the position of the bending plate 641 when it is attached to the bending rod 643 is higher, the upward supporting force of the upper adhesive tape is increased, so that the adhesive tape is shaped between the bending plate 641 and the friction shaft 32 when passing between the bending plate 641 and the friction shaft 32, and the generation of wrinkles is reduced when the adhesive tape is attached.

[0050] When the adhesive tape passes between the friction shaft 32 and the bending plate 641, the surface of the bending plate 641 is connected with the friction rod 645, and the friction between the adhesive tape and the bending plate 641 is generated when the adhesive tape is pulled tight. The dust attached to the surface of the adhesive tape is bounced off and slides down to the surface of the slide 36 along the inwardly inclined bending piece 336. Since the slide 36 is inclined, the dust bounced off from the surface of the adhesive tape is easily collected into the sliding groove 35.

[0051] The foam adhesive tape is made of EVA or PE foam as a base material, which is coated with solvent type (or hot melt type) pressure sensitive adhesive on one side or both sides, and then is coated with release paper. The adhesive tape is usually wound for storage. When the adhesive tape passes between the elastic support assembly 6 and the friction shaft 32, the elastic support assembly 6 and the friction shaft 32 are staggered, so that the adhesive tape is attached to the elastic support assembly 6 and contacts the friction shaft 32 at the same time. When the adhesive tape is pulled out, it is attached to the surface of the support frame 64 and extrudes the support frame 64, so that the support frame 64 pulls and supports the adhesive tape between the fixed circular plate 331 and the shaft seat 34, and shapes the bent adhesive tape.

[0052] The elastic rod 647 is of elastic material and is bent downward after being extruded. When it is bent, the sliding block 646 at the upper end is clamped between the bending rods 643, so as to maintain the stability of the adhesive tape when it passes through the bending plate 641. After the adhesive tape is pulled and transported, the pressure on the elastic rod 647 disappears, driving the bending plate 641 to reset.

[0053] When the adhesive tape is pulled, the bending plate 641 is pressed, the friction rod 645 is pressed to slide on the surface of the sliding block 646, and the elastic rod 647 is pressed to be attached to the surface of the bending rod 643, supporting the adhesive tape during the pulling process. Because the bending radius of the adhesive tape is different when it is wound, the bending radius of the adhesive tape is small when it is used at the beginning, and the surface of the adhesive tape is relatively flat. During the pulling process, the adhesive tape is easily straightened and attached to the surface of the photovoltaic module. The worker rotates the screw rod 62, and the screw rod 62 drives the fixed table 61 to move away from the side of the side support block 648, so that the bending angle of the bending rod 643 becomes gentle. At this time, when the bending plate 641 is pressed to be attached to the bending rod 643, the upward supporting force of the adhesive tape is small, which avoids over-supporting the relatively flat adhesive tape and causes the adhesive tape to be wrinkled in the opposite direction.

[0054] The two bending rods 643 are provided with an insert piece 642, which supports between the two bending rods 643 when the bending plate 641 is pressed. Prevent the pressure on the two bending rods 643 from being uneven, which affects the stability of the adhesive tape conveying and causes deviation during attachment.

[0055] The worker places the photovoltaic module on the surface of the pressing plate 4, and the pressing plate 4 is affected by gravity to fall down and drive the connecting rod 54 on the surface of the rotating rod 55 to rotate downward. At this time, the short shaft 52 is affected by the connecting rod 54 to drive the rotating piece 53 to rotate with the sliding cutter 51, and to generate friction with the surface of the friction shaft 32 to cut the adhesive tape.

[0056] The worker places the photovoltaic module on the surface of the pressing plate 4, and then attaches the pulled adhesive tape to the surface of the photovoltaic module. Because the position between the elastic pad 514 and the friction shaft 32 is close after the pressing plate 4 is pressed to fall down, when the attachment is completed, the worker presses the pressing block 517 on both sides downward, so that the pressing block 517 slides on the surface of the elastic pad 514 and presses the torn adhesive tape, so that the adhesive tape can be more closely attached to the photovoltaic module.

[0057] The circular arc plate 511 is arranged at the side of the friction shaft 32, and the side scraping groove 513 is used to grind the edge of the adhesive tape to improve the flatness of the adhesive tape.

[0058] The worker presses the pressing block 517 downward, so that the pressing block 517 drives the insert block 515 to rotate, and the cutting piece 516 is in contact with the adhesive tape during rotation to cut the adhesive tape, which is convenient for the worker to cut off the adhesive tape after attachment.
