Description

Technical Field

[0001] This utility model relates to the field of welding strip manufacturing, specifically a high-efficiency welding strip manufacturing equipment. Background Technology

[0002] A solar cell stringer is an automated device that connects solar cells into a string. The stringing machine uses a mechanical transmission mechanism to transport the battery cells, and simultaneously applies a welding strip to the transported battery cells. Finally, the welding strip and battery cells are welded together using high-temperature gas from a hot air duct. In a common implementation, battery cells are typically connected into battery strings using solder ribbons. For example, the front end of the solder ribbon is soldered to the front main grid line of the front battery cell, and the rear end of the same solder ribbon is soldered to the back main grid line of the rear battery cell. This allows adjacent battery cells to be welded together using solder ribbons. In this process, the fabrication of the solder ribbon is a crucial step, as the speed of solder ribbon fabrication directly affects the welding efficiency. Currently, solder ribbon fabrication is basically a single-pass process, meaning that after the entire solder ribbon is fabricated, another solder ribbon is made for the next welding operation. Obviously, this single-pass process is not efficient enough and can easily affect the welding efficiency in the later stages. Therefore, it is necessary to design an efficient welding strip manufacturing equipment to make the welding strip manufacturing process faster, thereby improving welding efficiency. Utility Model Content

[0003] Purpose of the utility model: To provide a high-efficiency welding strip manufacturing equipment to solve the above-mentioned problems existing in the prior art.

[0004] Technical solution: A high-efficiency solder strip manufacturing equipment, comprising: The following components are arranged in sequence: belt pressing assembly, belt hammering assembly, belt cutting assembly, belt supporting assembly, belt pulling assembly, and belt tail fixing assembly; During installation, the belt pressing assembly, belt hammering assembly, belt cutting assembly, belt support assembly, belt pulling assembly, and belt tail fixing assembly can be installed in one housing or frame. The pull strap assembly and the support strap assembly are designed in two sets; Each pull belt assembly includes: The belt adjustment module includes a belt moving module (connected to the housing or frame) and a belt lifting module connected to the belt moving module; The belt pulling arm is designed in two sets. Each set includes a belt pulling frame connected to the belt pulling lifting module, a belt pulling motor located at the end of the belt pulling frame, a belt pulling screw connected to the output end of the belt pulling motor and inserted into the belt pulling frame, and a belt pulling movable frame sleeved on the belt pulling screw. The side of the pull belt frame is provided with a pull belt slide rail, and the side of the pull belt movable frame is provided with a pull belt slider that is adapted to the pull belt slide rail; The pull belt movable frame is provided with a plurality of pull belt movable teeth, and the pull belt frame is provided with a plurality of pull belt fixed teeth that are adapted to the pull belt movable teeth.

[0005] This invention utilizes a design with two sets of pull-tab assemblies for welding strip production. During welding strip production, these assemblies can work in an alternating manner. In the first set of pull-tab assemblies, the pull-tab arm closest to the slapping assembly first inserts the welding strip into the cutting assembly. Then, in the second set of pull-tab assemblies, the pull-tab arm furthest from the slapping assembly connects the welding strip. During this connection process, the pull-tab arm in the second set, closest to the slapping assembly, simultaneously inserts a new welding strip into the cutting assembly, which is then connected by the pull-tab arm in the first set, furthest from the slapping assembly. This reciprocating connection process forms a double-pass welding strip production system, improving welding strip production efficiency.

[0006] Meanwhile, the drive mechanism of the belt-pulling arm in this invention is achieved by a belt-pulling motor combined with a belt-pulling screw, which makes the control precision more accurate.

A belt-smashing cylinder is connected to the belt-smashing top frame, and the output end of the belt-smashing cylinder is provided with a belt-smashing base frame that abuts against the belt-smashing top frame.

A tape cutter is slidably engaged with the tape fixing frame, and a tape lifting cylinder with its output end connected to the tape cutter is installed on the tape lifting frame; By designing a welding strip assembly, the predetermined position of the weld is flattened, which facilitates the stacking of battery strings later and avoids the stacking of battery strings being affected by the stress of the welding strip.

[0010] In a further embodiment, each set of towing components includes: The carrier-mounted mobile module is connected to the housing or frame. The support plate is connected to the towing moving module; The solder strip is prevented from falling by designing the drag-carrying components.

[0011] In a further embodiment, the tail-fixing assembly includes: A tail-fixing plate is connected to the housing or frame, and a tail-fixing motor is mounted on the tail-fixing plate. The output end of the tail-fixing motor is provided with a cam. A movable plate with a tail is slidably fitted with a fixed plate with a tail, and the movable plate with a tail has a cam groove that matches the cam. The comb teeth with tails are mounted on the tail fixing plate; A tail-mounted fixing clamp, connected to the tail-mounted fixing plate, includes a clamp arm connecting shaft inserted into the tail-mounted fixing plate, and two sets of clamp arms hinged to the clamp arm connecting shaft. A spring is provided between the two sets of clamp arms below or above the clamp arm connecting shaft. A clamping arm closing block is installed on the movable plate with a tail, and the clamping arm closing block has a clamping arm slot that is adapted to the tail fixing clamp. The tail of the welding strip is fixed by a tail fixing component, and the welding strip is straightened by a pull arm, which facilitates the subsequent placement of the welding strip and the battery cell.

[0012] Beneficial Effects: This utility model discloses a high-efficiency welding strip manufacturing equipment. This utility model uses two sets of pulling components to manufacture welding strips. During the manufacturing process, the pulling arms of the first pulling component, which are closer to the slapping component, first thread the welding strip into the cutting component.

During the connection process, the pulling arms of the second group, which are closer to the slapping component, simultaneously thread new welding strips into the cutting component, and the pulling arms of the first group, which are farther away from the slapping component, connect them. This process is repeated to form a double-pass welding strip manufacturing process, thereby improving the welding strip manufacturing efficiency. Attached Figure Description

In the first set of pull-tab assemblies 256, the pull-tab arm 2563 closest to the slapping assembly 252 first inserts the welding strip into the cutting assembly 253. Then, the pull-tab arm 2563 in the second set of pull-tab assemblies 256, furthest from the slapping assembly 252, connects the welding strip. During the connection process, the pull-tab arm 2563 in the second set, closest to the slapping assembly 252, simultaneously inserts a new welding strip into the cutting assembly 253, and the pull-tab arm 2563 in the first set of pull-tab assemblies 256, furthest from the slapping assembly 252, connects it. This reciprocating connection process forms a double-pass welding strip manufacturing process, improving the welding strip manufacturing efficiency.

A belt pressing cylinder 2513 is installed on the belt pressing swing frame 2512. The output end of the belt pressing swing frame 2512 is provided with a belt pressing top frame 2514. A belt pressing block 2515 is provided on the belt pressing top frame 2514. The welding strip is pressed down by the design of the pressing assembly 251 to prevent the welding strip from falling when it is not under the tension of the pulling arm 2563.

By designing the welding strip assembly 252, the predetermined position of the weld is flattened, which facilitates the stacking of battery strings later and avoids the stacking of battery strings being affected by the stress of the welding strip.

[0028] Each towing assembly includes: The carrier-mounted moving module 2542 is connected to the housing or frame; The support plate 2541 is connected to the towing moving module; By designing a drag-carrying component, the solder strip is prevented from falling, thus achieving control over the solder strip.

The tail of the welding strip is fixed by a tail fixing component 255, and the welding strip is straightened by a pull arm 2563, which facilitates the subsequent placement of the welding strip and the battery cell.

[0030] The belt moving module 2561, belt lifting module 2562, and belt supporting moving module 2542 are all linear motion modules, which are existing technologies. They can include a module frame, a module motor installed at the end of the module frame, a module lead screw connected to the output end of the module motor and inserted into the module frame, and a module slider sleeved on the module lead screw and slidingly engaged with the module frame.

[0031] Working principle description: Let the two sets of pull belt assemblies 256 be pull belt group one and pull belt group two respectively. In pull belt group one and pull belt group two, the pull belt arm 2563 closer to the snapping belt assembly 252 is designated as arm one, and the pull belt arm 2563 farther away from the snapping belt assembly 252 is designated as arm two. During operation, the welding strip is passed through the pressing assembly 251 and the pressing assembly 252. The welding strip is then clamped by the first middle arm of the first pulling assembly and passed into the cutting assembly 253. The second middle arm of the second pulling assembly connects the welding strip that has passed through the cutting assembly 253. As the welding strip is continuously pulled out, when the pulling assembly reaches the required welding length, the pulling assembly 253 cuts the pulling assembly. At this time, the unloaded end of the welding strip is supported by the support assembly 254. The second middle arm of the second pulling assembly continues to move, driving the welding strip to the predetermined position. The cut end of the welding strip is fixed by the tail fixing assembly 255. The second middle arm of the second pulling assembly continues to move and straighten the welding strip. After the welding strip is straightened, the tail fixing assembly 255 releases the fixing of the welding strip, and the second middle arm of the second pulling assembly places the welding strip in the predetermined position (this process is carried out by two sets of pulling assemblies 256, which can work alternately to improve the efficiency of the strip production). During the tape pulling process, the middle position of the welding tape is flattened by the tape-smashing assembly 252, which makes it easier to weld the front part of the welding tape to the front main grid line of the front cell and the rear part of the same welding tape to the back main grid line of the rear cell (at the same time, it is also easy to stack the battery strings after welding). When the pressing assembly 251 is working, the pressing swing frame 2512 is attached to the pressing base frame 2511 and fixed by the fastener. Then, the pressing cylinder 2513 drives the pressing top frame 2514 to descend, and the pressing block 2515 presses the welding strip (to prevent the welding strip from moving due to its own weight during manufacturing. When the pulling arm 2563 moves, it releases the pressing work). When the strip-smashing assembly 252 is working, the strip-smashing cylinder 2523 drives the strip-smashing base frame 2521 to rise until it contacts the strip-smashing top frame 2522, causing the welding strip located between the strip-smashing base frame 2521 and the strip-smashing top frame 2522 to be flattened. When the strip cutting assembly 253 is working, the strip cutting lifting cylinder 2533 drives the strip cutting lifting frame 2532 to move, and then the cutting blade lifting cylinder 2534 drives the welding strip cutter 2535 to move upward, so that the welding strip cutter 2535 contacts the strip cutting top frame 2536, thereby cutting the welding strip between the strip cutting top frame 2536 and the welding strip cutter 2535 (the dual cylinders are designed here mainly for compact design. A single cylinder would require a longer design, which would not meet the size requirement. Therefore, the dual cylinders are designed to add up to obtain a long cylinder stroke). When the support assembly 254 is working, the support moving module 2542 drives the support plate to move, thereby supporting the welding strip; When the tail fixing assembly 255 is working, the tail fixing motor 2553 drives the cam to move in the cam groove, causing the tail movable plate 2551 to move up and down. When the tail movable plate 2551 rises, the clamping arm closing block 2551A rises, and the end of the tail fixing clamp 2551B closes in the clamping arm groove, so that the tail fixing clamp 2551B is in a loose state. When it is necessary to clamp the welding strip, the fixing motor drives the clamping arm closing block 2551A to fall. Through the action of the spring, the end of the tail fixing clamp 2551B closes, completing the clamping of the welding strip. When the belt pulling assembly 256 is working, the belt pulling moving module 2561 and the belt pulling lifting module 2562 adjust the position of the belt pulling arm 2563, and then the belt pulling motor 2563E drives the belt pulling screw 2563B to rotate, so that the belt pulling movable frame 2563C moves along the belt pulling frame 2563A, thereby bringing the belt pulling movable tooth 2563C1 closer to the belt pulling fixed tooth 2563A1, thereby fixing the welding strip, and then pulling the welding strip to move.
