Description

Technical Field

[0001] This application relates to the field of material conveying, specifically a conveying device. Background Technology

[0002] When conveying materials (such as battery strings), the carrier is equipped with adsorption holes to prevent the materials from shifting relative to the carrier. These adsorption holes continuously adsorb the materials during the conveying process.

[0003] In existing conveying devices, the supporting mechanism is connected to an air extraction device via a flexible air tube. This tube moves synchronously with the supporting mechanism to extract air from the adsorption holes on the supporting mechanism in real time. The problem with this extraction method is that when the conveying stroke is long, the excessively long, drooping flexible air tube is prone to entanglement, friction, and interference with other moving parts during movement, posing a risk of breakage or damage. Furthermore, the swaying of the flexible air tube increases the vibration of the supporting mechanism, affecting the stability of the conveying process. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a conveying device, the detailed technical solution of which is as follows:

[0005] A conveying device includes a conveying mechanism, a carrying mechanism, and a vacuum block, wherein:

[0006] The conveying mechanism is used to convey the bearing mechanism along the first direction. The air extraction block is set below the bearing mechanism and extends along the conveying path of the conveying mechanism. The upper surface of the air extraction block is provided with several air extraction slots arranged at intervals along the first direction. An air extraction passage is provided inside the air extraction block. Each air extraction slot is provided with a one-way valve. The one-way valve is used to control the opening and closing between the corresponding air extraction slot and the air extraction passage. The air extraction passage is connected to an external air extraction device through an air pipe.

[0007] The bearing surface of the bearing mechanism is provided with adsorption holes, and the bottom of the bearing mechanism is fixedly provided with a docking air block that is in contact with the upper surface of the suction block. The docking air block is provided with a docking air groove extending in the first direction on the surface of the docking air block that is in contact with the suction block. The docking air groove is connected to the adsorption holes.

[0008] During the process of conveying the carrying mechanism, the docking air block moves on the upper surface of the suction block, and the docking air groove can always dock with at least one suction groove.

[0009] When the docking gas tank is docked with the extraction gas tank, the one-way valve in the extraction gas tank opens, and the extraction gas tank connects the extraction gas path and the docking gas tank, so that the adsorption hole generates adsorption force.

[0010] When the docking air tank and the extraction air tank are separated, the one-way valve in the extraction air tank closes, sealing the extraction air tank.

[0011] The conveying device provided in this application has an air extraction block positioned below the carrying mechanism and extending along the conveying path of the conveying mechanism. A docking air block, which is in real-time connected to the air extraction block, is located at the bottom of the carrying mechanism. During conveying, the air extraction block extracts air from the adsorption holes on the carrying mechanism via the docking air block, thereby ensuring that the carrying mechanism can continuously adsorb materials. With this conveying device, the carrying mechanism no longer needs to be connected to the air extraction device via a flexible air pipe, thus avoiding the risk of breakage or damage to the flexible air pipe during movement and improving conveying stability.

[0012] In some embodiments, a first magnet is provided in the docking groove; an air extraction hole communicating with the air extraction passage is provided on the inner wall of the extraction groove; the one-way valve includes a floating plug, a spring, and a second magnet, wherein the floating plug includes a blocking section and an installation section arranged vertically, the diameter of the blocking section is larger than the diameter of the installation section, and the peripheral wall of the blocking section is in contact with the inner wall of the extraction groove; the spring is sleeved on the installation section, the lower end of the spring abuts against the bottom of the extraction groove, and the upper end of the spring abuts against the blocking section; the second magnet is provided at the top of the blocking section, and the second magnet and the first magnet are arranged with the same poles opposite each other so that the second magnet and the first magnet repel each other; when the docking groove and the extraction groove are docked, the first magnet pushes the floating plug downward through the second magnet, the blocking section and the air extraction hole are misaligned, so that the one-way valve opens and the spring is compressed and contracted; when the docking groove and the extraction groove are separated, the spring pushes the floating plug upward to reset, the blocking section blocks the air extraction hole, so that the one-way valve closes.

[0013] By installing a first magnet inside the docking air groove and configuring a one-way valve comprising a floating plug, a spring, and a second magnet, the one-way valve automatically opens when the docking air groove aligns with the extraction air groove due to the mutual repulsion between the first and second magnets. This allows the extraction block to draw air from the suction holes on the supporting mechanism via the docking air groove. When the docking air groove separates from the extraction air groove, the one-way valve automatically closes under the action of the spring, thus preventing air leakage from the extraction air groove separated from the docking air groove.

[0014] Furthermore, the automatic opening and closing of the check valve is triggered entirely by the magnetic force of the first and second magnets, without relying on additional control circuits and algorithms, thus reducing equipment costs and improving the reliability of the check valve.

[0015] In some embodiments, the inner wall of the suction groove is provided with a suction hole communicating with the suction air passage. The one-way valve includes a floating plug and a lifting drive. The floating plug is movably disposed in the suction groove and connected to the drive end of the lifting drive. When the docking groove is docked with the suction groove, the lifting drive pulls the floating plug downward, and the floating plug is misaligned with the suction hole, so that the one-way valve opens. When the docking groove is separated from the suction groove, the lifting drive pushes the floating plug upward, and the floating plug blocks the suction hole, so that the one-way valve closes.

[0016] An alternative one-way valve structure is provided. When the docking air groove and the suction air groove are docked, the lifting drive controls the floating plug to descend and offset from the suction port, thereby opening the one-way valve and allowing the suction block to suction air from the adsorption holes on the supporting unit via the docking air block. When the docking air groove and the suction air groove are separated, the lifting drive controls the floating plug to rise and block the suction port, thereby closing the one-way valve and preventing air leakage from the suction air groove separated from the docking air groove.

[0017] In some embodiments, the lifting drive is an electromagnet, a cylinder, or an electric cylinder.

[0018] Several simple and stable lifting drive components are provided, all of which can drive the floating piston to lift and lower, so as to quickly open and close the one-way valve.

[0019] In some embodiments, the length of the docking air groove in the first direction is greater than the center distance between two adjacent air extraction grooves, so that the docking air groove always remains docked with at least one air extraction groove during the conveying process.

[0020] By setting the length of the docking air groove in the first direction to be greater than the center distance between two adjacent air extraction grooves, it is ensured that the docking air groove is always docked with at least one air extraction groove during the conveying process.

[0021] In some embodiments, a flexible pad is provided on at least one of the upper surface of the suction block and the lower surface of the docking block, and the upper surface of the suction block and the lower surface of the docking block slide in contact to form an airtight fit.

[0022] By placing a flexible pad on at least one of the upper surface of the vacuum block and the lower surface of the docking block, an airtight fit can be formed when the upper surface of the vacuum block and the lower surface of the docking block slide in contact, thus preventing air leakage.

[0023] In some embodiments, the supporting mechanism includes two supporting plates spaced apart along a second direction, the second direction being perpendicular to the first direction; the bottom of each of the two supporting plates is provided with a docking air block; the conveying mechanism includes two sets of conveying units spaced apart along the second direction, the two sets of conveying units corresponding one-to-one with the two supporting plates, the two supporting plates respectively bearing on the corresponding conveying units, and the two sets of conveying units being configured for synchronous conveying; two air extraction blocks are provided, the two air extraction blocks being spaced apart along the second direction and corresponding one-to-one with the two docking air blocks.

[0024] By configuring the carrying mechanism to include two carrying plates spaced apart along a second direction, and making corresponding arrangements to the conveying mechanism, each carrying mechanism can carry and convey two pairs of first-class materials with an operating gap in between, or carry and convey one second-class material, thereby improving the versatility of this application.

[0025] In some embodiments, the conveying mechanism includes a driving pulley, a driven pulley, and a conveyor belt. The conveyor belt is fitted onto the driving pulley and the driven pulley and conveys along a first direction. A first positioning tooth is provided on the inner side of the conveyor belt. The conveyor belt meshes with the driving pulley and the driven pulley through the first positioning tooth. A second positioning tooth is also provided on the conveying surface of the conveyor belt. A toothed plate is installed at the bottom of the carrying mechanism. A plurality of tooth grooves are arranged side by side at intervals along the first direction on the toothed plate. The carrying mechanism meshes with the second positioning tooth on the conveyor belt through the tooth grooves.

[0026] The inner surface of the conveyor belt engages with the driving and driven pulleys via the first positioning teeth, improving the conveying stability of the conveyor belt and preventing slippage. By installing a toothed plate with grooves at the bottom of the carrying mechanism and setting a second positioning tooth on the conveying surface of the conveyor belt, the carrying mechanism can be engaged and positioned on the conveying surface of the conveyor belt, preventing positional deviation of the carrying mechanism during conveying.

[0027] In some embodiments, the conveying mechanism includes a driving sprocket, a driven sprocket, and a conveying chain. The conveying chain is fitted onto the driving sprocket and the driven sprocket and conveys along a first direction. A pin plate is installed at the bottom of the carrying mechanism. A plurality of pins are arranged side by side at intervals along the first direction at the bottom of the pin plate. The carrying mechanism is connected to the chain groove on the conveying chain via the pins.

[0028] The conveyor chain is mounted on the drive and driven sprockets to ensure the stability of the conveyor chain and prevent slippage. A pin plate with a pin is installed at the bottom of the carrying mechanism, allowing the carrying mechanism to be positioned on the conveyor chain via the pin, preventing positional shifts during transport.

[0029] In some embodiments, the conveying mechanism further includes two guide rails extending along a first direction, the guide rails being spaced apart on both sides of the conveyor belt or conveyor chain along a second direction, the carrying mechanism being slidably connected to each guide rail, the guide rails being used to cooperate with the conveyor belt or conveyor chain to carry the carrying mechanism and to guide the carrying mechanism during conveying.

[0030] By setting guide rails, the stability of the load-bearing and conveying mechanism is further improved, and positional deviation or deflection of the load-bearing mechanism is avoided. Attached Figure Description

[0046] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] As described in the background section, in existing conveying devices, the supporting mechanism is connected to an air extraction device via a flexible air tube. The flexible air tube moves synchronously with the supporting mechanism to perform real-time air extraction from the adsorption holes on the supporting mechanism. A problem with this extraction method is that when the conveying stroke of the device is long, the excessively long, drooping flexible air tube is prone to entanglement, friction, and interference with other moving parts during movement, posing a risk of breakage or damage. Furthermore, the swaying of the flexible air tube increases the vibration of the supporting mechanism, affecting the stability of the conveying process.

[0048] Therefore, this application provides a conveying device in which the flexible air tube does not need to move synchronously with the carrying mechanism, thus avoiding the risk of breakage or damage to the flexible air tube during movement and improving the conveying stability.

[0049] like Figures 1 to 9 As shown, the conveying device in this embodiment includes a conveying mechanism 1, a bearing mechanism 2, and a vacuum block 3, wherein:

[0050] The conveying mechanism 1 is used to convey the carrying mechanism 2 along the first direction. The air extraction block 3 is set below the carrying mechanism 2 and extends along the conveying path of the conveying mechanism 1. The upper surface of the air extraction block 3 is provided with a number of air extraction slots 31 arranged at intervals along the first direction (such as the X direction). The air extraction block 3 is provided with an air extraction passage 32. Each air extraction slot 31 is provided with a one-way valve 33. The one-way valve 33 is used to control the opening and closing between the corresponding air extraction slot 31 and the air extraction passage 32. The air extraction passage 32 is connected to an external air extraction device through an air pipe.

[0051] The bearing surface of the bearing mechanism 2 is provided with an adsorption hole 21. The bottom of the bearing mechanism 2 is fixedly provided with a docking air block 22 that is in contact with the upper surface of the suction block 3. The surface of the docking air block 22 that is in contact with the suction block 3 is provided with a docking air groove 23 extending in the first direction. The docking air groove 23 is connected to the adsorption hole 21.

[0052] During the process of conveying the carrying mechanism 2 by the conveying mechanism 1, the docking air block 22 moves on the upper surface of the suction block 3, and the docking air groove 23 can always dock with at least one suction groove 31 on the suction block 3. That is to say, as the docking air block 22 moves with the carrying mechanism 2, the docking air groove 23 on it docks with the suction groove 31 on the suction block 3 in sequence.

[0053] When the docking air groove 23 is docked with the extraction air groove 31 (i.e., the docking air groove 23 and the extraction air groove 31 are aligned vertically), the one-way valve 33 in the extraction air groove 31 is opened, and the extraction air groove 31 is connected to the extraction air passage 32 and the docking air groove 23, so that the adsorption hole 21 continuously generates adsorption force.

[0054] When the docking air groove 23 separates from the extraction air groove 31, the one-way valve 33 in the extraction air groove 31 closes, sealing the extraction air groove 31, thereby preventing air leakage from the extraction air groove 31 that has separated from the docking air groove 23.

[0055] As can be seen, by setting up an air extraction block 3 extending along the conveying path of the conveying mechanism 1, and setting a docking air block 22 at the bottom of the carrying mechanism 2 that is in real-time connected to the air extraction block 3, the air extraction block 3 can perform real-time air extraction on the adsorption holes 21 on the carrying mechanism 2 through the docking air block 22 during the conveying process, thereby ensuring that the carrying mechanism 2 can achieve continuous adsorption of materials. The air pipe connected to the air extraction device only needs to be connected to the air extraction block 3 to perform unified air extraction on each air extraction slot 31 on the air extraction block 3. It does not need to be connected to the carrying mechanism 2 and moves with the carrying mechanism 2, thereby avoiding the risk of tearing or breaking the air pipe during the movement and improving the conveying stability.

[0056] The conveying device of this application is capable of conveying materials such as battery strings awaiting processing.

[0057] In order to carry and transport multiple materials, the conveying device of this application includes multiple carrying mechanisms 2 supported on the conveying mechanism 1.

[0058] For example, in the cell string arrangement, multiple cell strings need to be arranged on the support mechanism 2 to obtain the cell string group required for the photovoltaic module, and the arranged cell string group is then transported to the downstream processing station (such as the busbar welding station, film application station, etc.) for processing. During the arrangement process, each support mechanism 2 only carries a cell unit consisting of one longer cell string or two shorter cell strings. However, a cell string group in a photovoltaic module usually includes several cell units, so at least a corresponding number of support mechanisms 2 are required.

[0059] like Figures 6 to 9 As shown, in some embodiments, a first magnet 24 is provided inside the docking air groove 23. An air extraction hole 34 communicating with the air extraction passage 32 is provided on the inner wall of the air extraction groove 31. The one-way valve 33 includes a floating plug 331, a spring 332, and a second magnet 333, wherein:

[0060] The floating plug 331 includes a blocking section 331a and an installation section 331b arranged vertically. The diameter of the blocking section 331a is larger than the diameter of the installation section 331b, and the peripheral wall of the blocking section 331a fits against the inner wall of the suction groove 31.

[0061] Spring 332 is sleeved on mounting section 331b, with its lower end abutting the bottom of suction groove 31 and its upper end abutting the sealing section 331a. Second magnet 333 is positioned at the top of sealing section 331a. Second magnet 333 and first magnet 24 are arranged with the same poles facing each other, so that they repel each other. That is, the magnetic polarities of the opposite sides of the second magnet 333 and the first magnet 24 are the same.

[0062] When the docking air groove 23 aligns with the suction groove 31, the first magnet 24 pushes the floating plug 331 downward via the second magnet 333, causing the sealing section 331a to be misaligned from the suction port 34, thus opening the one-way valve 33 and compressing the spring 332. The suction port 34, misaligned from the sealing section 331a, connects to the suction groove 31 and the suction air passage 32, enabling the suction device to extract air from the adsorption hole 21 through the air pipe, the suction air passage 32, and the docking air groove 23.

[0063] When the docking air groove 23 separates from the suction groove 31, the first magnet 24 releases the pressure on the second magnet 333, the spring 332 extends and resets, thereby pushing the floating plug 331 to rise and reset, and the sealing section 331a re-seals the suction hole 34 so that the one-way valve 33 closes.

[0064] As can be seen, by setting a first magnet 24 in the docking air groove 23 and configuring the one-way valve 33 as consisting of a floating plug 331, a spring 332, and a second magnet 333, the one-way valve 33 can be automatically triggered to open when the docking air groove 23 docks with the suction groove 31, thereby allowing the suction block 3 to suction air from the adsorption hole 21 on the bearing mechanism 2 via the docking air block 22. When the docking air groove 23 separates from the suction groove 31, the one-way valve 33 is automatically triggered to close, thereby preventing air leakage from the suction groove 31 separated from the docking air groove 23.

[0065] Furthermore, the automatic opening and closing of the one-way valve 33 is triggered entirely by the magnetic force of the first magnet 24 and the second magnet 333, without relying on additional control circuits and control algorithms, thereby reducing equipment costs and improving the reliability of the one-way valve 33.

[0066] The one-way valve 33 can also be implemented in other ways. For example, in some other embodiments, the one-way valve 33 includes a floating plug and a lifting drive. The floating plug is movably disposed in the suction groove 31 and connected to the drive end of the lifting drive. When the docking groove 23 docks with the suction groove 31, the lifting drive pulls the floating plug downward, and the floating plug is misaligned with the suction hole 34, so that the one-way valve 33 opens. When the docking groove 23 separates from the suction groove 31, the lifting drive pushes the floating plug upward, and the floating plug blocks the suction hole 34, so that the one-way valve 33 closes.

[0067] The one-way valve 33 structure of this configuration can also achieve the following: when the docking air groove 23 is docked with the extraction air groove 31, the one-way valve 33 opens, allowing the extraction block 3 to extract air from the adsorption hole 21 on the bearing unit 2 via the docking air block 22. When the docking air groove 23 is separated from the extraction air groove 31, the one-way valve 33 closes to prevent air leakage from the extraction air groove 31 separated from the docking air groove 23.

[0068] To ensure rapid response of the lifting drive, the following is achieved: when the docking air groove 23 aligns with the suction groove 31, the lifting drive synchronously pulls the floating plug downward; when the docking air groove 23 separates from the suction groove 31, the lifting drive synchronously pushes the floating plug upward. An optional implementation involves installing a sensor within each docking air groove 23, with the sensor connected to the control terminal of the lifting drive. When the docking air groove 23 aligns with the suction groove 31, the sensor generates a first sensing signal to trigger the lifting drive to pull the floating plug downward. When the docking air groove 23 separates from the suction groove 31, the sensor generates a second sensing signal to trigger the lifting drive to push the floating plug upward.

[0069] In some embodiments, the lifting drive is an electromagnet, a cylinder or an electric cylinder, all of which can drive the floating plug 331 to rise and fall, so as to implement the rapid opening and closing of the one-way valve 33.

[0070] like Figure 7 As shown, in some embodiments, the length of the docking air groove 23 in the first direction is greater than the center distance between two adjacent suction grooves 31. This arrangement ensures that during the conveying process, the docking air groove 23 on the docking air block 22 at the bottom of the carrying mechanism 2 is always docked with at least one suction groove 31, ultimately ensuring that the adsorption holes on the carrying mechanism 2 can continuously generate adsorption force for adsorbing materials.

[0071] In some embodiments, a flexible pad is provided on at least one of the upper surface of the suction block 3 and the lower surface of the docking air block 22, and the upper surface of the suction block 3 and the lower surface of the docking air block 22 slide in contact to form an airtight fit, thereby preventing air leakage at the contact point between the suction block 3 and the docking air block 22.

[0072] As mentioned above, in some applications, the support mechanism 2 needs to support two pairs of materials, such as two battery strings that make up a battery cell, and an operating gap needs to be left between the two materials.

[0073] like Figures 1 to 2 As shown, in some embodiments, the support mechanism 2 includes two support plates spaced apart along a second direction (such as the Y-axis direction), such as the first support plate 25 and the second support plate 26 in the figure, and the second direction is perpendicular to the first direction.

[0074] Each of the two support plates has a docking air block 22 at its bottom. Correspondingly, the conveying mechanism 1 includes two sets of conveying units 10 spaced apart along the second direction. The two sets of conveying units 10 correspond one-to-one with the two support plates, and the two support plates are respectively supported on the corresponding conveying units 10. The two sets of conveying units 10 are configured for synchronous conveying. Two air extraction blocks 3 are also correspondingly provided, spaced apart along the second direction, and each corresponds one-to-one with the two docking air blocks 22.

[0075] By configuring the carrying mechanism 2 to include two carrying plates spaced apart along the second direction, and by making corresponding arrangements for the conveying mechanism 1 and the vacuum block 3, each carrying mechanism 2 can carry and convey two pairs of first-type materials (e.g., short battery strings), and ensure that both first-type materials are adsorbed, forming an operating gap between the two first-type materials.

[0076] Of course, the two support plates of the support mechanism 2 can also be used to support and transport a second type of material (such as a long battery string).

[0077] like Figures 1 to 3 and Figure 10 As shown, in some embodiments, the conveying mechanism 1 includes a driving pulley 11, a driven pulley 12, and a conveyor belt 13. The conveyor belt 13 is fitted onto the driving pulley 11 and the driven pulley 12 and conveys along a first direction. The inner side of the conveyor belt 13 is provided with a first positioning tooth 14. The conveyor belt 13 meshes with the driving pulley 11 and the driven pulley 12 through the first positioning tooth 14. The conveying surface of the conveyor belt 13 is also provided with a second positioning tooth 15. The bottom of the bearing mechanism 2 is equipped with a toothed plate 27. The toothed plate 27 is provided with a plurality of toothed grooves arranged side by side along the first direction. The bearing mechanism 2 meshes with the second positioning tooth 15 on the conveyor belt 13 through the toothed grooves.

[0078] The conveyor belt 13, which is mounted on the drive pulley 11 and the driven pulley 12 via the first positioning teeth 14, is used to transport the carrying mechanism 2, ensuring that the conveyor belt 13 provides stable transport to the carrying mechanism 2 and preventing the conveyor belt 13 from slipping.

[0079] By installing a toothed plate 27 with toothed grooves at the bottom of the carrying mechanism 2 and setting a second positioning tooth 15 on the conveying surface of the conveyor belt 13, the carrying mechanism 2 can be engaged and positioned on the conveying surface of the conveyor belt 13, thus preventing the carrying mechanism 2 from shifting position during the conveying process.

[0080] To further improve the conveying stability of the bearing mechanism 2, a toothed synchronous belt with zero gap can be used as the conveyor belt 13, and a toothed plate with zero gap can be used as the conveyor plate 27.

[0081] like Figure 11As shown, in some other embodiments, the conveying mechanism 1 includes a driving sprocket, a driven sprocket, and a conveying chain 16. The conveying chain 16 is mounted on the driving sprocket and the driven sprocket and conveys along a first direction. The bottom of the carrying mechanism 2 is equipped with a pin plate 28. The bottom of the pin plate 28 is provided with a plurality of pins 29 arranged side by side at intervals along the first direction. The carrying mechanism 2 is connected to the chain groove on the conveying chain 16 via the pins 29.

[0082] The conveyor chain 16, which is fitted onto the driving sprocket and driven sprocket, is used to transport the carrying mechanism 2, which also ensures stable transport of the carrying mechanism 2. By installing a pin plate 28 with a pin 29 at the bottom of the carrying mechanism 2, the carrying mechanism 2 is positioned on the conveyor chain 16 by the pin 29, thus preventing the carrying mechanism 2 from shifting during transport.

[0083] To further improve the conveying stability of the bearing mechanism 2, a zero-gap conveying chain 16 and a zero-gap pin plate 28 can be used.

[0084] like Figures 1 to 3 As shown, in some embodiments, the conveying mechanism 1 further includes two guide rails 17 extending along a first direction. The guide rails 17 are spaced apart on both sides of the conveyor belt 13 or the conveyor chain 16 along a second direction. The carrying mechanism 2 is slidably connected to each guide rail 17. The guide rails 17 are used to cooperate with the conveyor belt 13 or the conveyor chain 16 to carry the carrying mechanism 2 and to guide the carrying mechanism 2.

[0085] By setting guide rail 17, the stability of bearing and conveying of the bearing mechanism 2 is further improved, and positional deviation and deflection of the bearing mechanism 2 are avoided.

[0086] This application provides a sufficiently detailed and specific description. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within its protection scope. The scope of protection claimed in this application is defined by the claims, not by the above descriptions in the embodiments.
