Description

Technical Field

[0001] This application relates to the field of sheet conveying technology, specifically to a conveying mechanism. Background Technology

[0002] In industrial production, material conveying is one of the key links. Common conveying mechanisms include a support frame and drums mounted on the support frame, a conveyor belt, and a drive unit. The conveyor belt is wound around the drums, and the drive unit drives the drums to rotate, thereby driving the conveyor belt to move continuously or step by step.

[0003] However, in actual operation, such as Figure 8 As shown, due to installation errors, external interference, and other reasons, the conveyor belt 100 may experience belt misalignment. When misalignment occurs, one side of the conveyor belt 100 moves away from the center of the drum pulley 200, while the other side moves closer to the center of the drum pulley 200. At this time, the side of the belt closer to the center of the drum pulley 200 will be higher than the other side. Because the center of the drum pulley 200 is higher, during the automatic correction process of the drum pulley 200, the side of the conveyor belt 100 that is closer to or at the center of the drum pulley 200 will lift up, causing a significant reduction in the contact area between the conveyor belt 100 and the material with a flat bottom surface. This results in a significant decrease in static friction, increasing the risk of material slippage. Utility Model Content

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0046] Please refer to Figure 1 and Figure 2 , in some embodiments, the present application provides a conveying mechanism, the conveying mechanism comprising a bearing part 1 and a conveying part 2 and a driving part 3 mounted on the bearing part 1, wherein:

[0047] The bearing part 1 is the base support part of the whole conveying mechanism, which plays a role of fixing and supporting the conveying part 2 and the driving part 3. The common bearing part 1 structure is frame type, for example, T-shaped frame made of aluminum alloy or steel material, which is formed by welding, bolt connection and the like, and has strong stability, can adapt to different installation environment and load requirements, and is widely applied.

[0048] The conveying part 2 includes at least one conveying belt 23 and a driving wheel 21 and a driven wheel 22 arranged corresponding to each conveying belt 23. The driving wheel 21 and the driven wheel 22 are both drum-shaped wheels. The outer surface of the drum-shaped wheel for contacting the conveying belt 23 includes a straight section 211 extending in the circumferential direction and two inclined sections 212, the straight section 211 is located in the middle of the outer surface, the two inclined sections 212 are respectively located on both sides of the straight section 211, the straight section 211 and the inclined section 212 are smoothly connected, and the distance between each inclined section 212 and the drum-shaped wheel axis gradually decreases in the direction away from the straight section 211. The special design of the drum-shaped wheel can keep the part of the conveying belt 23 located in the straight section 211 substantially horizontal when the conveying belt 23 deviates, so that the conveying belt 23 still has more contact surface with the material (such as photovoltaic cell sheet and other sheet materials with flat bottom surface), which ensures the static friction force and effectively avoids the material slipping. At the same time, the design of the inclined section 212 ensures that the tension forces on both sides of the deviated conveying belt 23 are different, which can promote the deviated conveying belt 23 to correct itself to the appropriate position.

[0049] The driving part 3 is configured to drive the driving wheel 21 to rotate, thereby driving the conveying belt 23 to move. The driving part 3 usually includes a motor 31 and a transmission component 32. The motor 31 is a power source, and common motors include alternating current motor, direct current motor and the like. The transmission component 32 can be belt transmission, chain transmission or gear transmission and the like. Taking the belt transmission as an example, the output shaft of the motor 31 is connected with the rotating shaft of the driving wheel 21 through the belt. When the motor 31 operates, the driving wheel 21 is driven to rotate through the belt, thereby realizing the movement of the conveying belt 23.

[0050] Please refer to Figure 2 In one possible embodiment, the inclined section 212 continuously extends from the edge of the straight section 211 to the edge of the outer surface of the drum-shaped wheel, so that the shape transition of the drum-shaped wheel is smoother, which is beneficial to the conveying belt 23 to more naturally adapt to the change of the surface of the drum-shaped wheel during operation, reduces the problems such as wear or unstable operation of the conveying belt 23 caused by the sudden change of the shape of the drum-shaped wheel, and improves the overall reliability and durability of the conveying mechanism. Alternatively, the inclined section 212 can be a plane or a curved surface.

[0051] Please refer to Figure 1As shown in one possible embodiment, the conveying part 2 comprises at least one conveying belt 23 arranged in parallel, each conveying belt 23 corresponding driving wheel 21 is rotatably mounted on the bearing part 1 through the same driving shaft 27, and the driving part 3 rotates the driving shaft 27 to realize the synchronous rotation of each driving wheel 21. At least one conveying belt 23 arranged in parallel is used to carry and transport the materials.

[0052] Specifically, the bearing part 1 is provided with a driving shaft 27 penetrating the center of each driving wheel 21 of the conveying belt 23. The driving shaft 27 is rotatably mounted on the bearing part 1 through a bearing, which reduces friction and ensures the flexible rotation of the driving shaft 27. The center hole of each driving wheel 21 is tightly fitted on the driving shaft 27. The output shaft of the motor 31 of the driving part 3 is connected to the driving shaft 27 through a transmission part 32, which ensures that the power of the motor 31 can be stably transmitted to the driving shaft 27.

[0053] This structure ensures the synchronization of the movement of each conveying belt 23 and improves the stability of material conveying. For example, in the production line of photovoltaic cells, the cells are transported by multiple conveying belts 23 arranged in parallel, which improves the stability of the cells and avoids the deflection of the cells during the conveying process, facilitating subsequent processing operations. At the same time, the driving structure is simplified, the equipment cost and maintenance difficulty are reduced, and the failure points caused by multiple driving parts 3 are reduced.

[0054] Referring to Figure 1 As shown in one specific embodiment, the conveying part 2 comprises two conveying belts 23 arranged in parallel, and the bottom surface of the cell is placed on the two conveying belts 23 during the conveying process, which ensures the stability of the conveying belt 23.

[0055] Referring to Figure 1 and Figure 3 As shown in one possible embodiment, the conveying part 2 further comprises a flat key 24, the driving wheel 21 is sleeved on the driving shaft 27, the outer side of the driving shaft 27 is provided with a first flat key groove (not shown), the inner side of the driving wheel 21 is provided with a second flat key groove 25, the first flat key groove and the second flat key groove 25 are positionally corresponding to form a receiving hole, and the flat key 24 is embedded in the receiving hole to connect the driving shaft 27 and the driving wheel 21 in rotation.

[0056] Specifically, the first flat key groove on the driving shaft 27 and the second flat key groove 25 on the inner side of the driving wheel 21 are positionally accurately corresponding during processing. The flat key 24 is generally a metal strip with a rectangular cross section, and the material is usually 45# steel or other steel materials with high strength and wear resistance. During installation, the flat key 24 is embedded in the receiving hole formed by the two flat key grooves, the side surface of the flat key 24 is tightly fitted in the key groove, and the circumferential fixation between the driving shaft 27 and the driving wheel 21 is realized to prevent the relative rotation of the two.

[0057] The design of the flat key 24 achieves a firm connection between the driving shaft 27 and the driving wheel 21, ensuring effective power transmission. During the conveying process, the phenomenon of slipping between the driving shaft 27 and the driving wheel 21 is avoided, ensuring the stable operation of the conveyor belt 23. In addition, the connection of the flat key 24 is convenient for assembly and maintenance. When it is necessary to replace the driving wheel 21 or the driving shaft 27, only the flat key 24 needs to be removed for operation.

[0058] Please refer to Figure 1 In one possible embodiment, the conveying mechanism further includes a tensioning portion 26, which includes a rocker arm 261 adjustably mounted on the carrier portion 1 through a first screw position, and the driven wheel 22 is rotatably mounted on the rocker arm 261. The rocker arm 261 can drive the driven wheel 22 away from the driving wheel 21 to tension the conveyor belt 23.

[0059] Specifically, a first waist hole 263 in the shape of a long strip is formed on the rocker arm 261 along the conveying direction of the conveyor belt 23. At least one first threaded hole with internal threads is formed on the carrier portion 1, and a corresponding number of first screws are fixedly connected to the first waist hole 263 and the first threaded hole through threads, so as to adjustably mount the rocker arm 261 on the carrier portion 1. A bearing seat is mounted on the rocker arm 261, and the rotating shaft of the driven wheel 22 is mounted in the bearing seat through a bearing, so that the driven wheel 22 can rotate flexibly. When adjusting the tension of the conveyor belt 23, the first screw is loosened, and the rocker arm 261 can move along the conveying direction on the carrier portion 1, so as to change the distance between the driven wheel 22 and the driving wheel 21, and further adjust the tension of the conveyor belt 23. This structure design facilitates the operator to flexibly adjust the position of the driven wheel 22 according to the actual situation of the conveyor belt 23, effectively tension the conveyor belt 23, and ensure that the conveyor belt 23 always maintains appropriate tension, preventing the conveyor belt 23 from relaxing and affecting the material conveying effect, such as avoiding material jamming and unstable conveying speed, and ensuring smooth conveying.

[0060] Please refer to Figure 1 In one possible embodiment, the tensioning portion 26 further includes a limiting block 262 and a limiting bolt (not shown). The limiting block 262 is fixedly mounted on the carrier portion 1 and located on the side of the rocker arm 261 close to the driving wheel 21. The limiting block 262 is provided with a threaded through hole extending towards the rocker arm 261, and the limiting bolt is threadedly connected with the threaded through hole. The end of the limiting bolt abuts against the side of the rocker arm 261 close to the driving wheel 21.

[0061] Specifically, the limiting block 262 is welded or bolted on the bearing part 1, and is located close to the rocker arm 261 and on the side of the rocker arm 261 close to the driving wheel 21. The limiting block 262 is provided with a threaded hole, and the limiting bolt is screwed into the threaded hole. By rotating the limiting bolt, the distance between the end of the limiting bolt and the rocker arm 261 can be adjusted. In actual operation, after the conveying belt 23 is installed on the two drum wheels, the end of the limiting bolt is abutted against the rocker arm 261 by screwing the limiting bolt, and the conveying belt 23 reaches a predetermined tensioning degree. When the tensioning degree of the conveying belt 23 is adjusted, the rocker arm 261 can be fixed by locking at least one first screw. At the same time, the limiting screw can also provide some auxiliary fixing effect to prevent the tensioning degree from changing. In this way, the movement of the driven wheel 22 towards the driving wheel 21 can be effectively limited, and the fixing effect of the position of the rocker arm 261 is further enhanced, so as to prevent the rocker arm 261 from being displaced due to vibration or other external factors during the conveying process, maintain the stable tensioning state of the conveying belt 23, and reduce the conveying accidents caused by the change of the tension of the conveying belt 23.

[0062] Referring to Figure 4 In another possible embodiment, a structure of a tensioning part 26 is additionally provided, which is composed of an adjusting block 264 and a tensioning wheel 265. The adjusting block 264 is adjustably mounted on the bearing part 1 by a second screw, and the tensioning wheel 265 is rotatably mounted on the adjusting block 264. The inner side of the conveying belt 23 passes around the tensioning wheel 265, and the adjusting block 264 can drive the tensioning wheel 265 to move to tension the conveying belt 23.

[0063] Specifically, the adjusting block 264 is provided with a second waist hole 266 extending in the vertical direction, and the bearing part 1 is provided with a second threaded hole threadedly matched with the second screw. The second screw passes through the second waist hole 266 and is threadedly matched with the second threaded hole, so as to adjustably mount the adjusting block 264 on the bearing part 1. The adjusting block 264 is provided with a rotating shaft, and the tensioning wheel 265 is rotatably mounted on the rotating shaft by a bearing, so that the tensioning wheel 265 can freely rotate. The inner side of the conveying belt 23 passes around the tensioning wheel 265, and when the adjusting block 264 moves along the second waist hole 266 on the bearing part 1, the height position of the tensioning wheel 265 changes, thereby adjusting the tensioning degree of the conveying belt 23. At this time, the rocker arm 261, the limiting block 262 and the limiting bolt and the like can not be provided, and a fixed shaft 28 can be fixedly mounted on the bearing part 1, and the driven wheel 22 is rotatably mounted on the fixed shaft 28 by a bearing.

[0064] Further, the tensioning part 26 further comprises at least one transition wheel 267, and the outer side of the conveying belt 23 passes around the transition wheel 267. The transition wheel 267 is configured to change the extension direction of the conveying belt 23.

[0065] The transition wheel 267 also adopts a drum wheel structure, which is installed on the bearing part 1 through a rotating shaft and a bearing in a similar manner to the tensioning wheel 265. The transition wheel 267 is located around the outer side of the conveying belt 23, and its position is set according to the conveying path and the tensioning requirement. The setting of the transition wheel 267 increases the contact area between the tensioning wheel 265 and the conveying belt 23, and improves the tensioning effect. Changing the extension direction of the conveying belt 23 makes the layout of the conveying belt 23 in the conveying process more reasonable, and better adapts to different installation spaces and conveying path requirements. For example, in a production workshop with limited space, the conveying line can be made more compact by changing the direction of the conveying belt 23 through the transition wheel 267. At the same time, it helps to optimize the stress condition of the conveying belt 23, reduces the wear and fatigue of the conveying belt 23, and improves its service life. In some cases, multiple transition wheels 267 can be provided to realize the turning of the conveying belt 23 in a complex space, which can avoid the interference of some mechanisms in certain cases. For example, the transition wheel 267 is provided with two, and the two transition wheels 267 can be arranged on the two sides of the tensioning wheel 265, respectively, and can apply force to the conveying belt 23 from both sides to work cooperatively with the tensioning wheel 265. This makes the stress of the conveying belt 23 more uniform during the tensioning process, avoiding the situation of excessive local stress.

[0066] Referring to Figure 1 In one possible embodiment, the conveying mechanism further includes a sensing piece 4, which can be installed on the top of the bearing part 1 for sensing the passing or staying materials. Common types of sensing pieces 4 include photoelectric sensing pieces and capacitive sensing pieces. The photoelectric sensing piece 4 is composed of a light-emitting element and a light-sensing element. When the materials pass, the light is blocked, and the light signal received by the light-sensing element changes, thereby triggering a counting or detection signal. The capacitive sensing piece 4 detects the change of the capacitance between the materials and the sensing piece 4 to determine the presence of the materials. The number of sensing pieces 4 can be one or more, and the function of the sensing piece 4 can be to count the materials or detect the arrival of the materials, or to have both functions.

[0067] By implementing the counting function of the materials, it is convenient for the production process to count and manage the production. For example, in a battery piece production line, the number of battery pieces is accurately counted through the sensing piece 4. At the same time, it can detect whether the conveying belt 23 is loaded with materials, and timely find abnormal conditions in the material conveying process, such as material missing or accumulation, etc., thereby improving the automation degree and monitoring ability of the production process, and avoiding production stagnation and product quality problems caused by abnormal material conveying.

[0068] Referring to Figures 5-7As shown, in one possible embodiment, the conveying unit 2 further includes an adsorption member 29. The adsorption member 29 is disposed between the upper and lower belt bodies of the conveyor belt 23, with the driving wheel 21 and the driven wheel 22 located at opposite ends of the adsorption member 29. The adsorption member 29 has an air inlet 291, an air outlet 292, and an airflow channel 293. The airflow channel 293 connects the air inlet 291 and the air outlet 292, allowing gas input from an external air source to the air inlet 291 to be blown out of the air outlet 292 through the airflow channel 293. The angle between the blowing direction of the air outlet 292 and the horizontal direction is acute. When the air outlet 292 blows air, the difference in gas velocity between the upper and lower surfaces of the material generates an adsorption force that causes the material to adhere to the conveyor belt 23, thereby increasing static friction and preventing slippage.

[0069] Specifically, the adsorption element 29 is elongated and located between the upper and lower belts of the conveyor belt 23, with the driving pulley 21 and driven pulley 22 at its two ends, respectively. An airflow channel 293 is machined inside the adsorption element 29, with one end connected to an air inlet 291 and the other end connected to multiple air outlets 292. For example... Figure 7 and Figure 9 The air inlet angle of 292 is specially designed, horizontally ( Figure 9 The angle between the horizontal straight line in the middle and the blowing direction of the air inlet 292 is α, for example, an acute angle, and can be further selected in the range of 15°-60°, such as 15°, 26°, 40°, 55°, etc. An external air source is connected to the air inlet 291 through a pipe to provide gas to the adsorption element 29.

[0070] According to Bernoulli's principle, the blown airflow creates a relatively fast velocity on the lower surface of the material, resulting in a velocity difference with the airflow on the upper surface, thus generating an adsorption force. Therefore, when conveyor belt 23 transports materials, the airflow from the nozzle 292 ultimately creates an adsorption force on the material, causing it to adhere to the conveyor belt 23. This effectively increases the static friction between the material and the conveyor belt 23, further preventing the material from detaching from the conveyor belt 23 due to inertia or vibration during high-speed transport. This improves the accuracy and stability of material transport, reducing material loss and equipment malfunctions. For example, when transporting thin battery cells, it ensures that the cells are stably adsorbed onto the conveyor belt 23, preventing them from falling and causing damage.

[0071] Please see Figures 5-7As shown, in one specific embodiment, the suction accessory 29 is composed of a mounting block 294 and a cover plate 296.
