Description

Technical Field

[0001] This utility model relates to the field of speed reducer technology, specifically a speed reducer for a string welding machine. Background Technology

[0002] In the automated production of photovoltaic cells, string welding machines are one of the key pieces of equipment, used to precisely weld cells into strings. To improve production efficiency, modern string welding machines typically employ a dual-track parallel operation mode, where two conveyor tracks run synchronously to ensure welding accuracy and consistency. However, this dual-track structure requires two sets of synchronously driven output shafts to ensure that the movement of the two tracks is completely synchronized; otherwise, misalignment of the cells may occur, affecting the welding quality.

[0003] Traditional solutions typically employ two independent speed reducers to drive the two tracks separately, or use complex synchronous transmission mechanisms (such as timing belts, gearboxes, etc.) to achieve dual-axis output. However, using two speed reducers not only increases equipment cost and space requirements but may also lead to asynchronous output between the two axes, affecting system stability. Complex synchronous transmission mechanisms, on the other hand, suffer from structural complexity, assembly difficulties, and high maintenance costs, making it difficult to meet the photovoltaic industry's requirements for high precision, high reliability, and low cost.

[0004] Therefore, there is an urgent need for a dual-output shaft reducer specifically designed for string welding machines, which can achieve synchronous output of both shafts under a single power input, and features a compact structure and strong load-bearing capacity to meet the requirements of dual-rail string welding machines for photovoltaic cells. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dedicated speed reducer for string welding machines.

[0006] This reducer achieves dual-shaft output, ensuring complete consistency in the speed and torque of both shafts. This guarantees the synchronization of the dual-rail movement of the string welding machine and saves on the cost of motors and control systems. The reducer features a compact structure and a rigid and high-load-bearing transmission system. It saves on the cost of motors and control systems while reducing energy consumption, better meeting the cost reduction and efficiency improvement needs of the photovoltaic industry.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: the special reducer for string welding machine includes: a housing, an input shaft, and two output shafts;

[0008] The housing contains an input chamber, two deceleration chambers, and an output chamber.

[0009] An input shaft is disposed in the input chamber, and the input shaft is rotatably disposed in the input chamber via a first single-row deep groove ball bearing. An input gear is also provided in the input chamber.

[0010] Each reduction chamber output cavity is provided with an intermediate reduction assembly and an output gear. The intermediate reduction assembly includes an intermediate shaft, a first reduction gear, and a second reduction gear. The two ends of the intermediate shaft are rotatably mounted in the reduction chamber output cavity via two single-row deep groove ball bearings. The first reduction gear and the second reduction gear are coaxially mounted on the intermediate shaft, wherein the number of teeth of the first reduction gear is greater than the number of teeth of the second reduction gear. The first reduction gear meshes with the input gear; the second reduction gear meshes with the output gear.

[0011] The two ends of the output shaft are the connection end and the load end, respectively. The two output shafts extend into the output chambers of the two reduction chambers through their connection ends, and each output gear is set on the connection end of one output shaft.

[0012] Furthermore, the housing includes a housing body and an end cap body. The housing body is provided with an input hole, and the end cap body is provided with two output holes. The input hole is coaxial with the input shaft, and the two output holes are respectively coaxial with the two output shafts.

[0013] Furthermore, the outer walls of both output shafts are also provided with a rubber coating layer.

[0014] Furthermore, both output shafts are equipped with output covers at their load ends, which are secured to the output shafts by internal hexagonal head screws.

[0015] Furthermore, the two deceleration chamber output chambers are located on both sides of the input chamber, and the two deceleration chamber output chambers are symmetrically arranged relative to the input chamber.

[0016] Furthermore, the input chamber is also provided with a sun gear shaft, which is coaxially connected to the input shaft. The input gear is mounted on the sun gear shaft, and the input gear and the sun gear shaft are an integrated structure.

[0017] Furthermore, the housing is provided with an input mounting hole, which communicates with the input chamber. A clamping clip is also provided in the input mounting hole, and the clamping clip is connected to the end of the input shaft.

[0018] Furthermore, the sun gear shaft is rotatably supported in the input chamber by a second single-row deep groove ball bearing.

[0019] Furthermore, the two ends of the intermediate shaft are rotatably mounted in the output chamber of the deceleration chamber via a third single-row deep groove ball bearing and a fourth single-row deep groove ball bearing, respectively, and the output shaft is rotatably mounted in the output chamber of the deceleration chamber via a fifth single-row deep groove ball bearing and a sixth single-row deep groove ball bearing.

[0020] Furthermore, the input shaft is provided with a limiting ring, which axially limits the first single-row deep groove ball bearing.

[0021] Compared with the prior art, the beneficial effects of the special reducer for string welding machines in this utility model are as follows:

[0022] The reducer includes a housing, an input shaft, and two output shafts. The input and output shafts are driven by an intermediate reduction assembly, which includes an intermediate shaft, a first reduction gear, and a second reduction gear. The intermediate shaft is rotatably mounted in the output chamber of the reduction chamber via two single-row deep groove ball bearings at both ends. This reducer employs a one-in-two-out transmission structure, where the input shaft simultaneously drives both output shafts through the intermediate reduction assembly. This ensures that the speed and torque of the two shafts are completely identical, thereby guaranteeing the synchronicity of the dual-rail movement of the string welding machine, avoiding misalignment of the solar cells due to asynchrony, and improving welding quality.

[0023] The input shaft, intermediate shaft, and output shaft of this reducer are all supported by high-precision single-row deep groove ball bearings. The reducer adopts a symmetrical housing design, with two reduction chambers and the output chamber distributed on both sides of the input chamber. The internal transmission layout is reasonable, making the overall structure more compact. The transmission system has strong rigidity and load-bearing capacity, making it particularly suitable for the installation environment of photovoltaic string welding machines with limited space, ensuring stable operation under long-term high-load conditions.

[0024] This reducer only requires one drive motor to achieve synchronous output of two shafts. Compared with the traditional dual reducer solution, it can save the cost of motor and control system, while reducing energy consumption, which is more in line with the needs of the photovoltaic industry to reduce costs and increase efficiency.

[0035] refer to Figure 1 and Figure 2 A special reducer for a string welding machine includes a housing 100, an input shaft 200 and two output shafts 500; the housing 100 is provided with an input chamber and two reduction chamber output chambers; the two reduction chamber output chambers are located on both sides of the input chamber and are symmetrically arranged relative to the input chamber.

[0036] An input shaft 200 is disposed within the input chamber and is rotatably mounted within the input chamber via a first single-row deep groove ball bearing. An input gear 301 is also disposed within the input chamber. The input shaft 200 drives the input gear 301 to rotate synchronously. The input shaft 200 is used to connect to a drive motor.

[0037] Each reduction chamber output cavity is equipped with an intermediate reduction assembly 400 and an output gear 501. The intermediate reduction assembly 400 includes an intermediate shaft 401, a first reduction gear 402, and a second reduction gear 403. The intermediate shaft 401 is rotatably mounted in the reduction chamber output cavity via two single-row deep groove ball bearings at both ends. The first reduction gear 402 and the second reduction gear 403 are coaxially mounted on the intermediate shaft 401 and are connected to the intermediate shaft 401 by a key, allowing all three to rotate synchronously. The number of teeth on the first reduction gear 402 is greater than the number of teeth on the second reduction gear 403; the ratio of the number of teeth on the first reduction gear 402 to the number of teeth on the second reduction gear 403 is the reduction ratio of the intermediate reduction assembly 400. The first reduction gear 402 meshes with the input gear 301; the second reduction gear 403 meshes with the output gear 501. In this embodiment, all components of the two intermediate reduction assemblies 400 have the same specifications.

[0038] The two ends of the output shaft 500 are a connecting end and a load end, respectively. The two output shafts 500 extend into the output chambers of the two reduction gear chambers through their connecting ends. Each output gear 501 is mounted on the connecting end of one output shaft 500 and connected by a key. The output gear 501 drives the output shafts 500 to rotate synchronously. The two output shafts 500 are used to connect to a string welding machine.

[0039] The reducer adopts a one-in-two-out transmission structure. The input shaft 200 drives the two output shafts 500 simultaneously through the intermediate reduction assembly 400, ensuring that the speed and torque of the two shafts are completely consistent. This ensures the synchronicity of the dual-rail movement of the string welding machine, avoids cell alignment deviation caused by asynchrony, and improves welding quality.

[0040] The reducer adopts a symmetrical housing design with two reduction chambers and output chambers distributed on both sides of the input chamber, which optimizes the internal transmission layout and makes the overall structure more compact, making it particularly suitable for the installation environment of photovoltaic string welding machines in space-constrained environments.

[0041] In a preferred embodiment, the housing 100 includes a housing 101 and an end cap 102. The housing 100 has an input hole, and the end cap 102 has two output holes. The input hole is coaxial with the input shaft 200, and the two output holes are coaxial with the two output shafts 500, respectively. The end cap 102 is fixedly connected to the housing 101 by fastening screws, thus allowing the housing 100 to be opened for easy installation and maintenance of the reducer.

[0042] In a preferred embodiment, the outer walls of the two output shafts 500 are further provided with a rubber coating layer 502. Each output shaft 500 has an output cap 600 at its load end, and the output cap 600 is locked onto the output shaft 500 by an internal hexagon head screw 601.

[0043] In a preferred embodiment, the input chamber is further provided with a sun gear shaft 300, and the end of the input shaft 200 is provided with a mounting shaft hole 202. The end of the sun gear shaft 300 is inserted into the mounting shaft hole 202, and the two are connected by an interference fit, so that the sun gear shaft 300 and the input shaft 200 are coaxially connected and rotate synchronously. The input gear 301 is disposed on the sun gear shaft 300, and the input gear 301 and the sun gear shaft 300 are an integral structure.

[0044] In a preferred embodiment, the housing 101 is provided with an input mounting hole that communicates with the input chamber. A clamping clip 201 is also provided within the input mounting hole and is connected to the end of the input shaft 200. The clamping clip 201 facilitates the connection of the drive motor's rotating shaft to the input shaft 200.

[0045] In a preferred embodiment, the sun gear shaft 300 is rotatably supported in the input chamber by a second single-row deep groove ball bearing. The intermediate shaft 401 is rotatably mounted in the output chamber of the reduction chamber at both ends by a third and a fourth single-row deep groove ball bearing, respectively. The output shaft 500 is rotatably mounted in the output chamber of the reduction chamber by a fifth and a sixth single-row deep groove ball bearing. A retaining ring is provided on the input shaft 200, which axially limits the first single-row deep groove ball bearing. The third and fourth single-row deep groove ball bearings are of the same specification.

[0046] The input shaft 200, intermediate shaft 401 and output shaft 500 of the reducer are all supported by high-precision single-row deep groove ball bearings, which can make the rigidity and load-bearing capacity of the transmission system stronger and ensure that it can still operate stably under long-term high-load conditions.

[0047] The working principle of the special reducer for the string welding machine is as follows: the rotating shaft of the drive motor rotates, which drives the input shaft 200, the sun gear shaft 300 and the input gear 301 to rotate synchronously; the rotation of the input gear 301 drives the first reduction gear 402 meshing with it to rotate, thereby causing the intermediate shaft 401 and the second reduction gear 403 to rotate; the rotation of the second reduction gear 403 can drive the output shaft 500 to rotate through the output gear 501, thus achieving a one-in-two-out transmission effect.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
