Description

Technical Field

[0001] The invention relates to the technical field of stitch welding machines, in particular to an automated photovoltaic flexible component stitch welding machine. Background Art

[0002] In recent years, countries around the world have successively proposed the goal of "carbon neutrality". To achieve this goal, countries need to further increase the installed capacity of renewable energy such as photovoltaics and increase the proportion of renewable energy power generation. With the growing demand for photovoltaic new energy industries, reducing costs and increasing efficiency of photovoltaic products has become its core competitiveness. This requires new technological changes to promote it.

[0003] Traditional crystalline silicon battery components are not bendable. Although the power generation efficiency is significantly better than that of thin-film products, their cross-field applications are limited. Flexible and lightweight components have the high efficiency of traditional crystalline silicon components and the flexibility of thin-film components. They can be widely used in various fields. At the same time, they are easy to install and save costs. With the rise of BIPV, flexible and lightweight components have ushered in a broader market space with their special advantages.

[0004] The OPES series of lightweight, flexible and efficient modules weigh only 3.75kg per square meter. The advanced packaging composite materials and industry-leading technology make the lightweight modules flexible and can fit perfectly with the curved modules. The weight is as light as 5-8Kg, which is about 70% lighter than similar products. The module can be used in a variety of application scenarios such as color steel tile roofs with weak load-bearing capacity, curved carports, building facades, etc. It is easy to install, further improving the utilization rate of the roof, thereby achieving higher power generation benefits.

[0005] At present, the preparation equipment of flexible components is uneven. There is an important process in the production of flexible components: the welding of bus bars and diodes, and the welding of ECA strips and bus bars. The welding process of bus bars not only plays a role in connecting and conducting, but also plays a vital role in the quality and life of photovoltaic components.

[0006] Based on the above situation, we propose an efficient preparation device for OPES flexible components, which can realize the efficient preparation of OPES flexible components, and the overall qualification rate and quality of the components are greatly improved. Summary of the invention

Figure 4 shown.

[0070] The diode synchronous belt module 800 is provided with a hot head driving motor 801 .

[0077] The long side alignment screw rod module 502 is provided with a long side alignment wheel 502a;

[0078] The short side alignment module 503 is provided with a short side alignment wheel 503 a .

[0079] Lifting hand mechanism 600 Figure 1 shown.

[0080] It should be noted that all the components used above are prior art, and the connections between the components are made by combining the components together through the frame 700 as needed, so they are not described in detail but are shown through the drawings.

[0081] When in use, the busbar is pulled out from the welding tape roll 301, passes around the top guide wheel 302a, the weight guide wheel 302b in turn, and finally enters the welding tape cutter 303; the unwinding motor 301a is connected to the unwinding shaft through a coupling to control the unwinding speed so that the weight guide wheel 302b can achieve a balance with the internal tension of the busbar under the action of the counterweight block, thereby realizing an uninterrupted unwinding process.

[0082] Driven by the welding strip pulling motor 401a, the pulling double-acting sub-module 401 pulls the welding strip pulling clamp 401b to pull the bus strip out of the welding strip cutter 303 to a set length, and then cuts it. Then the welding strip pulling clamp 401b continues to pull the bus strip to the set position in sequence. At this time, the pressing machine 402b moves to the set position under the traction of the pressing synchronous belt module 402, extends downward to press the bus strip, and then the welding strip pulling clamp 401b retreats, and the bus bar falls into the preparation tray 304 with guide pins.

[0083] Next, the material preparation tray 304 is moved to the diode welding station under the traction of the cutting synchronous belt module 305. The first-level cylinder assembly 100, under the traction of the diode synchronous belt module 800, absorbs a diode from the diode carrier tape and places it at the joint between the two sections of the return strips. The first-level cylinder assembly 100 and the second-level cylinder assembly 200 are used for alternate downward pressure under the time-sharing control, and then welding is performed through the second-level cylinder assembly 200. A synthetic stone pad is provided under the diode to prevent the heat generated by welding from being conducted to the material preparation tray 304 through the pad.

[0084] At this time, the diode and the busbar are welded into a whole, and then the busbar suction claw frame 903d on the busbar welding mechanism 900 grabs the whole to the battery assembly for welding with the ECA strip. The mechanism realizes the movement of the Y axis and the Z axis under the control of the translation motor 901a and the lifting motor 902a. The electromagnetic induction welding head 903c installed on the aluminum profile realizes the downward pressure welding under the control of the lifting cylinder 903a. A spring guide column 903b is installed above the welding head to realize soft contact with the ECA strip.

[0085] Before the welding process, the battery assembly is transmitted to the inside of the machine through the assembly transmission mechanism 500. A transmission speed regulating motor is arranged on the transmission timing belt 501. The transmission speed regulating motor drags four transmission timing belts 501 to smoothly transport the assembly. The long side alignment wheels 502a and the short side alignment wheels 503a arranged around the assembly center the glass under the drive of the long side alignment screw module 502 and the short side alignment module 503.

[0086] After the battery assembly and the bus bar are welded, the lifting arm mechanism 600 lifts the battery assembly and places it on the glass, and then the material can be taken out.

[0087] In the present invention, by arranging two sets of busbar unwinding and cutting mechanisms 300, a busbar pulling and preparing mechanism 400 and a diode welding mechanism G, feeding and welding are performed alternately on the left and right sides, thereby improving the efficiency of busbar preparation and welding; at the same time, a precise positioning mechanism is arranged on the busbar preparation tray 304, and combined with the control method of cooperating with the servo motor and the relevant synchronous belt module, the entire preparation process can be completed quickly while ensuring high positioning accuracy.

[0088] In the present invention, the diode and the bus bar are welded by hot pressure conduction. At the same time, the welding tension is stabilized above the standard value by adding the technical means of flux-assisted welding, and the welding effect is greatly improved. The bus bar and the ECA strip are welded by electromagnetic induction welding, and the high-frequency oscillation circuit + current feedback system is used to accurately control the welding temperature, achieving technical indicators of high responsiveness, high temperature control accuracy, and high welding quality.

[0089] Example 2

[0096] When in use, the busbar passes through the rolling wheel 303e-2 and the upper limit pulley 303e-1 and is placed on the surface of the matching spring block 303e-32 on the tool matching block 303e-3. After the welding strip clamp 401b pulls the busbar to a certain position, the piston rod inside the cutting drive cylinder 303b is started to move upward, and the vertical block 303c moves upward synchronously. The downward pressing slide rod 303c-1 slides in the groove 303d-1 and drives the downward pressing block 303d to move upward, and the entire downward pressing block 303d rotates, and the spring cutting knife 303 d-3 contacts with the tool matching block 303e-3 and moves downward to cut the busbar. After completion, the piston rod inside the cutting drive cylinder 303b can be controlled to move downward, and then the welding strip clamp 401b pulls the cut busbar to the appropriate position and fixes it through the pressing machine 402b. The welding strip clamp 401b moves to the tool matching block 303e-3 and pushes the matching spring block 303e-32 to move, so that part of the busbar that has just been cut will leak out and then the welding strip clamp 401b can be controlled to clamp it.

[0105] When in use, start the hot head drive motor 801 to move the cylinder fixing plate 102 to the appropriate position, then start the mobile cylinder 103 and extend the piston rod thereon until the suction cup rod 105 contacts the diode, then start the vacuum equipment to suck the diode through the suction cup mouth, then control the piston rod on the mobile cylinder 103 to retract, and when the mobile cylinder fixing plate 102 is to the gap between the two bus bars, control the piston rod on the mobile cylinder 103 to extend and retract to a certain position again to make the diode contact the two bus bars.

[0106] When the driving cylinder 201 is controlled to drive the linear connecting block 202 to move downward, the spring column 203 and the heating block 204 move synchronously. The heating block 204 stops when it contacts the diode. The spring column 203 can reduce the impact force of the downward pressure, close the suction cup nozzle of the vacuum equipment and no longer absorb the diode. Then, the piston rod on the moving cylinder 103 is controlled to retract to the initial position, and the diode and the bus bar are welded through the heating block 204. The heating temperature is controlled by the thermocouple sensor.

[0107] It should be noted that the above equipment can be automatically controlled by PLC.

[0116] It should be noted that a torsion spring is provided at the hinge between the resistance plate 102a and the cylinder fixing plate 102, so that one end of the resistance plate 102a is in a tilted state.

[0117] The mobile cylinder 103 also includes a mobile limit groove 103d, a mobile limit rod 103e and a mobile air inlet nozzle 103f. The mobile limit groove 103d is arranged on the side of the mobile cylinder 103 and is connected to the main mobile air groove 103b. The mobile limit rod 103e is rotatably installed in the mobile limit groove 103d. The mobile air inlet nozzle 103f is arranged on the side of the mobile cylinder 103 for entering and exiting compressed gas into the mobile cylinder 103.

[0118] It should be noted that when a torsion spring is provided at the hinge of the movable limit rod 103e in the movable limit groove 103d, the limit rod 103e is always in a horizontal state, and the two ends of the movable limit rod 103e extend out from the movable limit groove 103d respectively, one end is located in the main movable air groove 103b, and the other end is located outside the movable cylinder 103.

[0119] The driving cylinder 201 includes a driving push plate 201a, a driving air groove 201b, a driving air inlet nozzle 201c and a driving air outlet nozzle 201d. The driving air groove 201b is arranged at the lower end of the driving cylinder 201, and the driving air inlet nozzle 201c and the driving air outlet nozzle 201d are arranged on the side of the driving cylinder 201. A driving push column 201a-1 is arranged on the side of the driving push plate 201a. The driving push column 201a-1 is inserted into the driving air groove 201b. When in use, the driving push plate 201a is controlled to move up and down by the driving air inlet nozzle 201c and the driving air outlet nozzle 201d.

[0120] An auxiliary plate 201a-2 is provided on the driving push column 201a-1, and the auxiliary plate 201a-2 is located at the upper end of the movable limit rod 103e. In this way, when the movable limit rod 103e does not rotate so that its entirety is located in the movable limit groove 103d, the auxiliary plate 201a-2 will move downward and collide with the movable limit rod 103e and cannot move.

[0121] An auxiliary push rod 201a-21 is arranged on the side of the auxiliary plate 201a-2, and an auxiliary sliding block 201a-22 is arranged on the side of the auxiliary push rod 201a-21. Two auxiliary push rods 201a-21 are symmetrically arranged along the center line of the auxiliary plate 201a-2, and the auxiliary sliding block 201a-22 is provided with rounded corners.

[0122] The mobile cylinder 103 also includes an unlocking slide groove 103g and a mobile unlocking groove 103h. The unlocking slide groove 103g and the mobile unlocking groove 103h are arranged on the side of the mobile cylinder 103. The unlocking slide groove 103g and the mobile unlocking groove 103h are connected. The mobile unlocking groove 103h is connected to the secondary mobile air groove 103c. The auxiliary sliding block 201a-22 is placed in the unlocking slide groove 103g.

[0123] Two groups of unlocking grooves 103g and movable unlocking grooves 103h are symmetrically arranged along the center line of the movable cylinder 103.

[0124] A secondary limit slot 103a-21 is provided on the circumferential surface of the secondary movable spring column 103a-2, and an arc spring block 103a-22 is provided in the secondary limit slot 103a-21. Under normal circumstances, the arc spring block 103a-22 extends out of the secondary limit slot 103a-21.

[0125] A main unlocking plate 103h-1 is arranged in the movable unlocking slot 103h, a bevel groove 103h-11 is arranged on the side of the main unlocking plate 103h-1, and an unlocking spring 103h-12 is arranged on the other side of the main unlocking plate 103h-1, and the unlocking spring 103h-12 is fixedly connected to the inside of the movable unlocking slot 103h.

[0126] When the main unlocking plate 103h-1 is not squeezed, the main unlocking plate 103h-1 and the side surface of the moving cylinder 103 remain on the same plane, and the inclined groove 103h-11 is connected to the unlocking sliding groove 103g.

[0127] An arc block 103h-13 is also provided on the side of the main unlocking plate 103h-1.

[0128] When in use, the slider plate 101 moves to the diode picking position on the diode synchronous belt module 800, and then the movable push plate 103a on the movable cylinder 103 is controlled to move downward by the movable air inlet nozzle 103f, thereby driving the suction cup rod 105 to move and contact the diode, and then the vacuum equipment is started to absorb the diode through the suction cup nozzle, and the movable air inlet nozzle 103f is no longer used for air intake but for air exhaustion, and under the action of the springs on the main movable spring column 103a-1 and the secondary movable spring column 103a-2, the push plate 103a moves upward and returns to the initial position without moving downward.

[0129] It should be noted that when the push plate 103a moves downward, it will squeeze and push the resistance plate 102a to rotate so that one end of it contacts the diode synchronous belt module 800, thereby reinforcing the position of the slider plate 101 to prevent it from moving. When the push plate 103a moves upward, the reinforcement is released.

[0130] It should be noted that during the process of sucking up the diode, the main moving spring column 103a-1 and the secondary moving spring column 103a-2 only move part of the position in the main moving air groove 103b and the secondary moving air groove 103c. At this time, the main moving spring column 103a-1 is not in contact with the moving limit rod 103e, and the arc spring block 103a-22 on the secondary moving spring column 103a-2 is not aligned with the moving unlocking groove 103h. The descending position of the main moving spring column 103a-1 and the secondary moving spring column 103a-2 can be limited by the diode picking platform.

[0131] When the moving cylinder fixing plate 102 is at the gap between the two bus bars, the moving push plate 103a on the moving cylinder 103 is controlled to move down to the maximum stroke again. At this time, the diode is in close contact with the bus bar; in this process, the main moving spring column 103a-1 squeezes and pushes the moving limit rod 103e to rotate so that it is completely placed in the moving limit groove 103d. At this time, the auxiliary plate 201a-2 on the driving push plate 201a can move down. When the secondary moving spring column 103a-2 moves to the bottom, the arc spring block 103a-22 on the secondary moving spring column 103a-2 extends out of the secondary limit slot 103a-21 and is placed in the moving unlocking slot 103h and contacts the arc block 103h-13. The secondary moving spring column 103a-2 is limited and cannot move up under the action of the spring on it, and the entire moving push plate 103a cannot move.

[0132] The driving cylinder 201 is controlled to drive the push plate 201a and the linear connection block 202 to move downward, the spring column 203 and the heating block 204 move synchronously, and the brass heating head 204a on the heating block 204 stops when pressing the diode, and the spring column 203 can reduce the impact of the downward pressure, and the vacuum device suction cup nozzle is closed to stop sucking the diode, and the heating device is started to weld the diode and the bus bar through the brass heating head 204a, and the heating temperature is controlled by the thermocouple sensor; in this process, the auxiliary push rod 201a-21 also moves synchronously and abuts against the flipped resistance plate 102a, and the auxiliary sliding block 201a-22 slides in the unlocking slot 103g, and when it slides to a positioning When the auxiliary sliding block 201a-22 is in the position, it enters the inclined groove 103h-11 on the main unlocking plate 103h-1, pushing the main unlocking plate 103h-1 to move in the movable unlocking groove 103h, and the arc block 103h-13 pushes the arc spring block 103a-22 to contract. When the auxiliary sliding block 201a-22 completely passes through the inclined groove 103h-11, the arc block 103h-13 pushes the arc spring block 103a-22 completely into the secondary limit slot 103a-21, and the two secondary movable spring columns 103a-2 are released from the restriction, and the entire movable push plate 103a retracts to the initial position, and at this time the brass heating head 204a presses the diode and the bus bar.

[0133] By setting the above-mentioned components, when the brass heating head 204a welds the diode and the bus bar, the suction cup nozzle must not contact the diode to avoid damage to the suction cup nozzle, and ensure that when the movable cylinder 103 picks up the diode, even if the driving cylinder 201 is erroneously operated, it cannot move for welding, thereby ensuring that the steps are carried out step by step and avoiding accidents.

[0134] The device operates stably and welds firmly, and the steps are locked by the cooperation of related components to avoid the influence of misoperation or program failure on the diode welding.
