Description

Technical Field

[0001] The present application relates to the field of battery manufacturing technology, and in particular to a conveying device, a conveying method and a battery production line. Background Art

[0002] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in energy storage fields.

[0003] During the battery manufacturing process, conveyors are typically required to transport batteries, allowing them to flow between various workstations for processing. During this process, batteries may experience abnormalities such as jams. If the likelihood of jams is not reduced or abnormalities such as jams are not promptly identified and resolved, batteries may accumulate within the conveyor, exacerbating the abnormality and impacting the stability and efficiency of the conveying process. Therefore, reducing the likelihood of jams and promptly identifying abnormalities to improve conveying efficiency is a topic of ongoing research in the industry. Summary of the Invention

[0004] In order to solve the above technical problems, the present application provides a conveying device, a conveying method and a battery production line that can reduce the possibility of material jamming and can promptly identify abnormal conveying conditions.

[0005] This application is implemented through the following technical solutions.

[0006] The first aspect of the present application provides a conveying device for conveying a carrier carrying batteries to a specified position, the conveying device comprising: a first rotating mechanism, comprising a rotatable ratchet, the ratchet comprising a plurality of ratchet teeth, the plurality of ratchet teeth being arranged along the circumference of the ratchet, the carrier having an engaging portion for engaging with the tooth grooves of the ratchet teeth; a second rotating mechanism, engaging with the first rotating mechanism and capable of rotating with the rotation of the first rotating mechanism, the second rotating mechanism comprising a rotatable turntable, the turntable comprising a plurality of grooves, the plurality of grooves being arranged along the circumference of the turntable for engaging with the engaging portion of the carrier; and an alarm mechanism, arranged on the outer periphery of the ratchet and forming a first conveying channel for the carrier to pass through between the ratchet and the ratchet; wherein the alarm mechanism is configured to emit a first alarm signal when in contact with the carrier.

[0007] Because the conveyor's first rotating mechanism includes a ratchet with multiple teeth and grooves, and the second rotating mechanism includes a rotating disk with multiple grooves, the carriers can be transported along a predetermined route as the first and second rotating mechanisms rotate, using a simple structure and simple operation. Furthermore, since each carrier's engaging portion only engages with one tooth or groove during transport, interference between them is eliminated. Consequently, material jamming is virtually eliminated during transport, improving both the stability and efficiency of the conveying process.

[0008] In addition, if the engaging portion of the carrier fails to engage with the tooth groove due to an unexpected situation such as tilting of the carrier, the carrier will contact the alarm mechanism under the push of the ratchet, thereby triggering the alarm mechanism to send out a first alarm signal. Therefore, the conveying device can promptly identify abnormal conditions in the conveying and send out an alarm signal in time to remind the operator to deal with the abnormal conditions in time, thereby improving the stability of the conveying process.

[0009] In some embodiments, the first alarm signal includes an alarm signal and / or a shutdown signal.

[0010] The first alarm signal may, for example, include an alarm signal for prompting, so that the operator can promptly detect abnormal conditions in the conveying process based on the alarm signal and promptly handle the abnormal conditions, thereby ensuring the stability of the conveying process. Furthermore, the first alarm signal may also include a stop signal, so that the conveying device can stop the conveying device according to the stop signal and wait for the operator to handle the abnormal conditions, thereby reducing the undesirable accumulation of carriers due to the continuous operation of the conveying device and improving the safety of the operator when handling the abnormal conditions.

[0011] In some embodiments, the ratchet includes a tooth tip portion on an outer circumferential surface adjacent to the tooth groove, and the tooth tip portion is used to push the carrier, whose engagement portion is not engaged with the tooth groove, toward the alarm mechanism.

[0012] As a result, a carrier that fails to engage the tooth grooves will not remain stuck in the material-stuck position. Instead, it will be propelled by the tooth tips away from the first rotating mechanism and toward the alarm mechanism, thereby contacting and triggering the alarm mechanism, allowing the alarm mechanism to promptly identify the abnormal conveying condition and issue the first alarm signal. Furthermore, since the carrier that has become stuck will be propelled away from the first rotating mechanism by the tooth tips, the possibility of the carrier remaining stuck in the material-stuck position and causing the first rotating mechanism to become jammed and damaged is reduced, thereby improving the reliability of the conveying device.

[0013] In some embodiments, the alarm mechanism includes: a first rib, which is provided on the outer periphery of the ratchet and can rotate relative to the outer periphery of the ratchet, and the first conveying channel is formed between the first rib and the ratchet; a trigger rod, which is located on the side of the first rib facing away from the ratchet and is fixedly connected to the first rib; and a material jam sensor, which is spaced apart from the trigger rod, and when the relative position between the material jam sensor and the trigger rod changes, the material jam sensor sends the first alarm signal.

[0014] Therefore, when the carrier, pushed by the tooth tips, contacts the alarm mechanism, it first contacts the first rib, causing it to rotate relative to the outer periphery of the ratchet, thereby driving the trigger lever fixed to the first rib to rotate together. At this time, the material jamming sensor, spaced apart from the trigger lever, detects the change in relative position with the trigger lever and issues a first alarm signal. The alarm mechanism has a simple structure, ingenious design, high sensitivity, and can automatically and promptly identify abnormal conveying conditions, thereby improving the reliability of the conveyor device.

[0015] In some embodiments, the first retaining edge includes a straight portion and a curved portion connected to each other, the curved portion is provided on the outer periphery of the ratchet, and the straight portion extends in a direction away from the ratchet; the conveying device also includes a baffle, which is located at an opposite side of the straight portion and forms a feed channel between the baffle and the straight portion, and the feed channel is connected to the first conveying channel. The carrier is conveyed to the ratchet via the feed channel, can engage with the tooth groove of the ratchet, and flow through the first conveying channel as the first rotating mechanism rotates.

[0016] In this way, the carrier can be transported to the first rotating mechanism according to the specified feeding path, reducing the possibility of the carrier being unable to engage with the tooth groove of the ratchet due to position offset during feeding, thereby causing material jamming.

[0017] In some embodiments, the trigger rod is connected to a connection position between the straight portion and the curved portion and is located outside the feeding channel.

[0018] Therefore, the trigger rod will not interfere with the carriers transported in the feeding channel and the first conveying channel and the batteries carried in the carriers, thereby ensuring the stability of the conveying process.

[0019] In some embodiments, the conveying device includes a height detection sensor for detecting the height of the battery carried in the carrier; the height detection sensor is arranged on the side of the feed channel close to the feed port, and when the height of the battery flowing into the feed channel exceeds a preset height, the height detection sensor sends a second alarm signal.

[0020] This allows the conveying device to promptly identify abnormal battery heights. Before the carrier enters the first conveying channel and while being conveyed within the feed channel, the height detection sensor will detect the height of the batteries carried within the carrier to determine whether the batteries are excessively high or abnormally high due to tilted placement. If an abnormal battery height is detected, the height detection sensor will issue a second alarm signal, promptly alerting the operator to address the abnormality.

[0021] In some embodiments, the conveying device includes a rotary drive device, which is used to drive the first rotating mechanism to rotate; the first rotating mechanism is connected to the output end of the rotary drive device through a coupling, and the coupling is disconnected from the output end of the rotary drive device according to the first alarm signal, thereby causing the first rotating mechanism to stop rotating.

[0022] Thus, the first rotating mechanism can be automatically rotated by the rotation drive device, thereby driving the carrier to be transported in a predetermined direction. Furthermore, upon receiving the first alarm signal, the coupling can disconnect from the output end of the rotation drive device, thereby shutting down the entire conveyor device and facilitating operator intervention in the event of an abnormal condition.

[0023] In some embodiments, the conveying device includes a second side guard, which is arranged on the outer periphery of the turntable and forms a second conveying channel between the second side guard and the turntable. The second conveying channel is connected to the first conveying channel. Along the conveying direction of the carrier, the second conveying channel is located downstream of the first conveying channel.

[0024] As a result, when the carrier is rotated and transported with the second rotating mechanism, it can be located between the groove and the second retaining edge, so that it can be transported according to the specified conveying route, reducing the possibility of the carrier's position shifting during the conveying process, making the conveying of the carrier more reliable.

[0025] In some embodiments, the conveying device also includes a color detection sensor, which is arranged in the second conveying channel and is used to detect the color of the top surface of the battery. When the color detection sensor detects that the color of the top surface of the battery is not a preset color, the color detection sensor sends a third alarm signal.

[0026] This allows the conveyor to promptly identify abnormal battery orientation. The conveyor uses a color detection sensor to detect the color of the top surface of the battery within the carrier, thereby determining whether the battery is placed in the carrier in the specified orientation. If an abnormal battery orientation is detected, the color detection sensor will issue a third alarm signal, prompting the operator to address the abnormality.

[0027] In some embodiments, the conveying device also includes a blocking mechanism, which is arranged in the feed channel; the blocking mechanism includes a blocking drive device and a block, and the block can rotate between a first position and a second position under the drive of the blocking drive device. The block is located in the first position, and the feed channel is connected to the first conveying channel, so that the carrier can flow into the first conveying channel. The block is located in the second position, blocking the carrier from flowing into the first conveying channel; when the first alarm signal is issued, the block rotates to the second position under the drive of the blocking drive device.

[0028] Therefore, when the alarm mechanism recognizes that the conveying device is in an abnormal state of material jamming and sends out a first alarm signal, the block can be rotated to the second position under the drive of the blocking drive device, thereby blocking the connection between the feed channel and the first conveying channel, so that the carriers conveyed by the feed channel cannot continue to be conveyed to the first conveying channel. In this way, no new carriers will flow into the first conveying channel before the operator has handled the abnormal state, reducing the possibility of the abnormal state becoming more serious due to the accumulation of carriers.

[0029] In some embodiments, after the second alarm signal is issued, the stopper is driven by the blocking drive device to rotate to the second position.

[0030] Therefore, when the height detection sensor recognizes that the battery carried in the carrier is in an abnormal state of height abnormality and issues a second alarm signal, the block can be rotated to the second position under the drive of the blocking drive device, thereby blocking the connection between the feed channel and the first conveying channel, so that the carrier conveyed by the feed channel cannot continue to be conveyed to the first conveying channel, thus making it easier for the operator to deal with the current abnormal state.

[0031] In some embodiments, after the third alarm signal is issued, the block is driven by the blocking drive device to rotate to the second position.

[0032] Therefore, when the color detection sensor recognizes that the battery carried in the carrier is in an abnormal state of being placed in the wrong direction and issues a second alarm signal, the block can be rotated to the second position under the drive of the blocking drive device, thereby blocking the connection between the feed channel and the first conveying channel, so that the carrier conveyed by the feed channel cannot continue to be conveyed to the first conveying channel, thereby making it easier for the operator to deal with the current abnormal state.

[0033] In some embodiments, the battery comprises a cylindrical battery, and the carrier comprises a cup for supporting the cylindrical battery.

[0034] Thus, the conveying device can convey the cylindrical batteries carried in the tray.

[0035] The second aspect of the present application provides a conveying method, which uses a conveying device to convey a carrier carrying batteries to a specified position, the conveying device including a first rotating mechanism, a second rotating mechanism and an alarm mechanism, the first rotating mechanism including a ratchet wheel configured to be able to rotate and having a plurality of ratchets, the second rotating mechanism including a turntable configured to be able to rotate and having a plurality of grooves, the carrier having an engaging portion for engaging with the tooth grooves of the ratchet teeth and the grooves of the turntable; the conveying method includes: a feeding step, causing the carrier carrying the batteries to flow to the first rotating mechanism; a first engaging step, causing the carrier to The engaging portion engages with the tooth groove of the ratchet; in the first conveying step, the carrier is conveyed to the second rotating mechanism through the rotation of the ratchet wheel of the first rotating mechanism; in the second engaging step, the engaging portion of the carrier is engaged with the groove of the turntable; in the second conveying step, the carrier is conveyed to the specified position through the rotation of the turntable of the second rotating mechanism; wherein, in the first engaging step, if the engaging portion of the carrier fails to engage with the tooth groove of the ratchet, the carrier contacts the alarm mechanism under the push of the ratchet wheel, and the alarm mechanism sends a first alarm signal.

[0036] Thus, by using the conveyor device, the transport of carriers carrying batteries can be achieved in a simple and automated manner, while reducing the possibility of carrier jams. In addition, if the conveyor device jams, the alarm mechanism can promptly identify the abnormal state of the jam and issue a first alarm signal to remind the operator to promptly address the abnormal state, thereby improving the stability of the conveying process.

[0037] In some embodiments, the conveying device includes a rotary drive device, which is used to drive the first rotating mechanism to rotate, and the first rotating mechanism is connected to the output end of the rotary drive device through a coupling; the conveying method also includes: a shutdown step, in which the coupling is disconnected from the output end of the rotary drive device according to the first alarm signal, thereby causing the first rotating mechanism to stop rotating; an alarm step, in which the conveying device issues an alarm notification according to the first alarm signal.

[0038] Therefore, when the alarm mechanism identifies the abnormal state of the conveying device with material jamming, it can stop the machine in time to avoid the abnormal state from becoming serious, and can issue an alarm notification to remind the operator to deal with the abnormal state.

[0039] In some embodiments, the conveying device includes a height detection sensor; before the first engagement step, the conveying method also includes: a height detection step, determining whether the height of the battery carried in the carrier exceeds a preset height; if it does not exceed the preset height, entering the first engagement step; if it exceeds the preset height, the height detection sensor sends a second alarm signal.

[0040] Thus, the conveying device can detect the height of the battery and promptly identify whether the battery is too high or tilted, and when the height of the battery is abnormal, promptly send out a second alarm signal to remind the operator to deal with the abnormal state.

[0041] In some embodiments, the conveying device includes a color detection sensor; the conveying method includes: a color detection step, determining whether the color of the top surface of the battery carried in the carrier is a preset color, if it is the preset color, continuing to convey the carrier, if it is not the preset color, the color detection sensor sends a third alarm signal.

[0042] Therefore, the conveying device can also detect the placement direction of the battery to promptly identify whether the placement direction of the battery is incorrect, and when the placement direction of the battery is abnormal, promptly send out a third alarm signal to remind the operator to deal with the abnormal state.

[0043] In some embodiments, the conveying device also includes a blocking mechanism, which includes a blocking drive device and a block. The block can rotate between a first position and a second position under the drive of the blocking drive device. The block is located at the first position to avoid the carrier, and the block is located at the second position to block the conveying of the carrier. The conveying method includes: a first blocking step, when the first alarm signal is issued, the block rotates to the second position under the drive of the blocking drive device.

[0044] Therefore, when the conveying device encounters an abnormal state of material jamming, the carrier in the feed channel can be blocked from continuing to be conveyed to the first conveying channel, thereby avoiding the abnormal state from becoming more serious.

[0045] In some embodiments, the conveying method includes: a second blocking step, when the second alarm signal is issued, the block is driven by the blocking drive device to rotate to the second position.

[0046] Therefore, when the battery carried by the carrier becomes highly abnormal, the carrier in the feed channel can be prevented from continuing to be conveyed to the first conveying channel, making it easier for operators to handle the current abnormal state.

[0047] In some embodiments, the conveying method includes: a third blocking step, when the third alarm signal is issued, the block is driven by the blocking drive device to rotate to the second position.

[0048] Therefore, when the batteries carried by the carrier are in an abnormal state of being placed in the wrong direction, the carrier in the feeding channel can be prevented from continuing to be conveyed to the first conveying channel, making it easier for operators to handle the current abnormal state.

[0049] The third aspect of the present application provides a battery production line, which includes: a carrier conveyor line for conveying carriers; and a conveying device provided according to the first aspect of the present application, the carrier conveyor line is connected to the first conveying channel of the conveying device; wherein, the battery includes a cylindrical battery, and the carrier includes a tray for carrying the cylindrical battery.

[0050] This allows for automated conveying of the trays carrying cylindrical batteries, while reducing the likelihood of the trays becoming stuck. Furthermore, if a tray becomes stuck, the battery height is abnormal, or the battery placement orientation is abnormal, the conveying device can promptly identify the abnormality and alert the operator to address it, thereby improving the stability of the conveying process.

[0051] In some embodiments, the battery production line further includes a welding station for welding the batteries conveyed by the conveying device.

[0052] In this way, the cylindrical batteries can be transported to the welding station for welding in a normal, orderly and efficient manner, which is beneficial to improving the transportation efficiency and ensuring the smooth progress of welding.

[0077] Below, this application is described in detail.

[0078] During the battery manufacturing process, conveying devices are usually required to connect various conveyor lines or workstations to transport batteries, allowing them to flow between various workstations for corresponding processing operations. However, during the conveying process, abnormal conditions such as material jamming may occur. That is, the battery may become stuck during the conveying process and cannot be smoothly transported. Material jamming will seriously affect the conveying efficiency, which greatly affects the production efficiency of batteries. Therefore, reducing the possibility of material jamming and thus improving the conveying efficiency of the conveying device will help improve the production cycle of the battery production line, thereby reducing production costs.

[0079] In addition, if the conveying device has already entered an abnormal state of material jamming, and the conveying device does not recognize the abnormal state and solve it in time, the batteries may accumulate in the conveying device, thereby aggravating the abnormal state, seriously affecting the stability of the conveying process, and may even cause damage to the batteries or the conveying device.

[0080] In response to the problems existing in the above-mentioned related technologies, the present application proposes a conveying device. The conveying device is used to convey a carrier carrying batteries to a specified position. The conveying device includes: a first rotating mechanism, a second rotating mechanism and an alarm mechanism. The first rotating mechanism includes a rotatable ratchet, the ratchet includes a plurality of ratchets, the plurality of ratchets are arranged along the circumference of the ratchet, and the carrier has an engaging portion for engaging with the tooth grooves of the ratchets. The second rotating mechanism is engaged with the first rotating mechanism and can rotate with the rotation of the first rotating mechanism. The second rotating mechanism includes a rotatable turntable, the turntable includes a plurality of grooves, the plurality of grooves are arranged along the circumference of the turntable, and is used to engage with the engaging portion of the carrier. The alarm mechanism is arranged on the outer periphery of the ratchet and forms a first conveying channel for the carrier to pass through between the ratchet and the alarm mechanism. Wherein, the alarm mechanism is configured to emit a first alarm signal when in contact with the carrier.

[0081] The conveying device of the present invention can convey the carrier carrying batteries with a simple structure and simple operation by meshing the carrier's meshing portion with the ratchet's tooth grooves and grooves. Furthermore, since each carrier's meshing portion only meshes with one tooth groove or one groove during conveying, there is no interference between the meshing portions. Therefore, material jamming is virtually eliminated during conveying, thereby improving the stability and efficiency of the conveying process.

[0082] In addition, if the engaging portion of the carrier fails to engage with the tooth groove due to an unexpected situation such as the tilt of the carrier, the carrier will contact the alarm mechanism under the push of the ratchet, thereby triggering the alarm mechanism to send out a first alarm signal. Therefore, the conveying device can promptly identify the abnormal state of the conveying and send out an alarm signal in time to remind the operator to deal with the abnormal state in time, thereby improving the stability of the conveying process and reducing the possibility of damage to the battery or the conveying device.

[0083] The conveying device of the embodiment of the present application can be used in the production process of batteries, for example, for conveying a tray carrying batteries, etc. Of course, those skilled in the art should understand that the conveying device provided in the embodiment of the present application is not only used to convey various trays carrying batteries in the battery production process, but can also be used to convey various other workpieces in the battery production process, or can also be used to convey other workpieces that need to be conveyed on other production lines.

[0086] like Figures 1 to 3 As shown, the present application provides a conveying device 100 for conveying a carrier 200 carrying batteries to a predetermined location. The conveying device 100 includes a first rotating mechanism 1, a second rotating mechanism 2, and an alarm mechanism 3. The first rotating mechanism 1 includes a rotatable ratchet 11 having a plurality of ratchet teeth 111 arranged circumferentially thereof. The carrier 200 has an engagement portion 201 for engaging with the tooth grooves 111a of the ratchet teeth 111. The second rotating mechanism 2 engages with the first rotating mechanism 1 and is capable of rotating with the rotation of the first rotating mechanism 1. The second rotating mechanism 2 includes a rotatable turntable 21 having a plurality of grooves 211 arranged circumferentially thereof for engaging with the engagement portion 201 of the carrier 200. The alarm mechanism 3 is disposed on the outer periphery of the ratchet 11 and forms a first conveying passage 10 between the ratchet 11 and the second rotating mechanism 2 for the carrier to pass through. The alarm mechanism is configured to emit a first alarm signal when in contact with the carrier.

[0087] In the manufacturing process of products such as batteries, it is usually necessary to connect various conveyor lines or workstations through a conveyor device to transport the batteries, so that the batteries can be transported and circulated between various conveyor lines and workstations for different processing operations. The conveyor device 100 of the embodiment of the present application is a device that can connect a carrier conveyor line and a processing device and can transport a carrier 200 carrying batteries between them.

[0088] In the embodiment of the present application, the battery is carried in the carrier 200 during transportation. The carrier 200 can provide certain protection for the battery, reducing the possibility of wear between the battery and the transportation device 100 and thus causing damage to the battery.

[0089] like Figure 6As shown, the carrier 200 of the embodiment of the present application is a cup, which is generally cylindrical and is used to support cylindrical batteries. Of course, in some other embodiments, the cup can also be any other suitable shape, such as a cube, a cuboid, etc., and can be specifically set according to the shape of the battery to be supported. Moreover, the carrier 200 does not necessarily have to be a cup, and can also be any other suitable carrier, such as a tray.

[0090] In the embodiment of the present application, the battery may be a battery cell.

[0091] A battery cell refers to a basic unit that can realize the mutual conversion of chemical energy and electrical energy. It can be used to make battery modules or battery packs, which are used to power electrical devices.

[0092] The battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be recharged to activate the active material after the battery cell is discharged and can be used continuously.

[0093] The battery cells can be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., which are not limited in the embodiments of the present application.

[0094] Although not shown, a battery cell generally includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are inserted and removed between the positive and negative electrodes. The separator is placed between the positive and negative electrodes to prevent short circuits between the positive and negative electrodes while allowing active ions to pass through.

[0095] In some embodiments, the battery cell also includes an electrolyte, which acts as a conductor of ions between the positive and negative electrodes. This application does not specifically limit the type of electrolyte, and the electrolyte can be selected based on needs. The electrolyte can be liquid, gel, or solid.

[0096] In some embodiments, a battery cell may include a housing. The housing is used to encapsulate components such as the electrode assembly and the electrolyte. The housing may be a steel housing, an aluminum housing, a plastic housing (e.g., polypropylene), a composite metal housing (e.g., a copper-aluminum composite housing), or an aluminum-plastic film.

[0097] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a soft-pack battery cell or a battery cell of other shapes. The prismatic battery cell includes a square-shell battery cell, a blade-shaped battery cell, and a polygonal battery. The polygonal battery is, for example, a hexagonal battery, etc. There is no special limitation in this application.

[0098] In some embodiments, the housing includes an end cap and a shell. The shell has an opening, and the end cap closes the opening to form a sealed space for accommodating the electrode assembly, electrolyte, and other substances. The shell may have one or more openings. One or more end caps may also be provided.

[0100] In some embodiments, the housing is provided with a pressure relief mechanism for releasing the internal pressure of the battery cell.

[0101] The following describes the conveying device 100 according to the embodiment of the present application with reference to the accompanying drawings. Figures 1 to 3 As shown, the conveying device 100 includes a first rotating mechanism 1 and a second rotating mechanism 2 .

[0102] It should be noted that Figure 1 R1 in the figure can be the height direction.

[0103] The first rotating mechanism 1 is a mechanism that can rotate around its own axis under the drive of a driving device (not shown in the figure). The second rotating mechanism 2 is engaged with the first rotating mechanism 1 and can rotate as the first rotating mechanism 1 rotates. In this way, the second rotating mechanism 2 no longer needs to be equipped with an additional driving device, which reduces the number of parts, reduces the development cost of the device, and is also beneficial to energy conservation and environmental protection.

[0104] Specifically, the first rotating mechanism 1 is provided with a first gear 12 along one side of its height direction, and the second rotating mechanism 2 is provided with a second gear 22 along one side of its height direction. The first gear 12 and the second gear 22 are located on the same side and mesh with each other. When the first rotating mechanism 1 rotates, the second rotating mechanism 2 rotates along with the rotation of the first rotating mechanism through the meshing of the second gear 22 with the first gear 12. This embodiment of the present application does not specifically limit the types of the first gear 12 and the second gear 22; they can be spur gears, helical gears, or any other suitable gears.

[0105] Of course, those skilled in the art should understand that in some other embodiments, the second rotating mechanism 2 may rotate around its own axis under the drive of the driving device, and the first rotating mechanism 1 may rotate as the second rotating mechanism 2 rotates. Alternatively, both the first rotating mechanism 1 and the second rotating mechanism 2 may be provided with a driving device.

[0106] In the embodiment of the present application, the first rotating mechanism 1 rotates counterclockwise, and the second rotating mechanism 2 rotates clockwise. In some other embodiments, the first rotating mechanism 1 may rotate clockwise, and the second rotating mechanism may rotate counterclockwise.

[0107] like Figure 1 and Figure 2 As shown, the first rotating mechanism 1 includes a ratchet 11 on the other side of its height direction. The ratchet refers to a gear with a rigid tooth shape on the outer edge or inner edge. The ratchet 11 rotates together with the rotation of the first rotating mechanism 1. In the embodiment of the present application, the outer edge of the ratchet 11 has a plurality of ratchet teeth 111, and the plurality of ratchet teeth 111 are evenly arranged along the circumference of the ratchet 11. The outer peripheral surface of the ratchet teeth 111 has a tooth groove 111a that is recessed toward the axial direction of the ratchet 11 and a tooth tip 111b that protrudes away from the axial direction. The tooth groove 111a and the tooth tip 111b are connected by a curved wall.

[0108] The second rotating mechanism 2 includes a rotating disk 21 on the other side thereof in the height direction. The rotating disk 21 rotates along with the second rotating mechanism 2. The rotating disk 21 includes a plurality of grooves 211 recessed toward its axis. The grooves 211 are evenly arranged along the circumference of the rotating disk 21.

[0109] like Figure 6 As shown, the outer wall of the carrier 200 is recessed toward its axial center to form an engaging portion 201 . The engaging portion 201 is used to engage with the tooth groove 111 a of the first rotating mechanism 1 and the groove 211 of the second rotating mechanism 2 .

[0110] In the embodiment of the present application, the supporting member 200 is a cylindrical support cup, and the outer surface of the engaging portion 201 of the support cup is arc-shaped. Therefore, the tooth groove 111a of the first rotating mechanism 1 and the groove 211 of the second rotating mechanism 2 are generally semicircular, and the curvature radius of the tooth groove 111a, the groove 211 and the engaging portion 201 is the same. In this way, the engaging portion of the supporting member 200 can be well engaged with the tooth groove 111a and the groove 211.

[0111] Of course, those skilled in the art should understand that the embodiment of the present application does not specifically limit the shapes of the tooth groove 111a, the groove 211 and the engaging portion 201, as long as the engaging portion 201 can engage with the tooth groove 111a and the groove 211.

[0112] In the embodiment of the present application, one tooth groove 111a and one groove 211 are each used to engage with one meshing portion 201 to transport one carrier 200. The first rotating mechanism 1 includes multiple tooth grooves 111a, and the second rotating mechanism 2 includes multiple grooves 211. The number of the multiple tooth grooves 111a corresponds to the number of the multiple grooves 211. In this way, multiple carriers 200 can be transported simultaneously, improving transportation efficiency. The embodiment of the present application does not specifically limit the number of tooth grooves 111a and grooves 211, and they can be specifically set according to the actual dimensions of the ratchet 11 and the rotating disk 21.

[0113] Because the first rotating mechanism 1 of the conveying device 100 includes a ratchet 11 having a plurality of tooth grooves 111a, and the second rotating mechanism 2 includes a turntable 21 having a plurality of grooves 211, the carrier 200 can be conveyed along a predetermined route with a simple structure and simple movement as the first rotating mechanism 1 and the second rotating mechanism 2 rotate by engaging its own engaging portion 201 with the tooth grooves 111a and the grooves 211. Furthermore, when the carrier 200 is being conveyed, because the engaging portion 201 of each carrier 200 only engages with one tooth groove 111a or one groove 211, the multiple carriers 200 will not interfere with each other. As long as the carrier 200 can smoothly engage with the tooth grooves 111a of the ratchet 11 during feeding, the material will hardly get stuck during the conveying process. Therefore, the possibility of material jamming in the conveying device 100 can be effectively reduced, thereby improving the stability of the conveying process and increasing the conveying efficiency.

[0114] like Figure 1 As shown, the first rotating mechanism 1 includes two ratchet wheels 11 spaced apart and coaxially arranged along the height direction. The ratchet teeth 111 of the two ratchet wheels 11 are aligned with each other along the height direction. That is, in a projection plane perpendicular to the height direction, the projections of the two ratchet wheels 11 overlap. As such, when the conveying device 100 conveys a carrier 200, the meshing portion 201 of the carrier 200 simultaneously engages with the tooth grooves 111a of both ratchet wheels 11, further improving meshing reliability and reducing the possibility of the meshing portion 201 disengaging from the tooth grooves 111a, which could cause material jamming.

[0115] Similarly, the second rotating mechanism 2 also includes two rotating disks 21, spaced apart and coaxially arranged along the height direction. The grooves 211 of the two rotating disks 21 are aligned with each other along the height direction. That is, in a projection plane perpendicular to the height direction, the projections of the two rotating disks 21 overlap. In this way, when the conveying device 100 conveys the carrier 200, the engaging portion 201 of the carrier 200 engages with the grooves 211 of both rotating disks 21 simultaneously, further improving engagement reliability and reducing the possibility of the engaging portion 201 and the groove 211 disengaging, which could cause material jamming.

[0116] Of course, those skilled in the art should understand that the embodiment of the present application does not specifically limit the number of ratchets 11 of the first rotating mechanism 1 and the turntable 21 of the second rotating mechanism 2. The first rotating mechanism 1 can include only one ratchet 11 or more (more than two) ratchets 11, and the second rotating mechanism 2 can include only one turntable 21 or more (more than two) turntables 21.

[0117] like Figure 1 and Figure 2 As shown, the conveying device 100 further includes an alarm mechanism 3, which can be mounted on a frame (not shown). The alarm mechanism 3 is disposed on the periphery of the ratchet 11 and forms a first conveying channel 10 for the carrier 200 to pass through between the alarm mechanism 3 and the ratchet 11.

[0118] If the carrier 200 successfully engages with the tooth groove 111a of the ratchet 11 of the first rotating mechanism 1 when entering the first conveying channel 10, it will smoothly pass through the first conveying channel 10 as the ratchet 11 rotates, thereby realizing the conveyance of the carrier 200, and the carrier 200 will not contact the alarm mechanism 3 on the outer periphery of the ratchet 11 when being conveyed in the first conveying channel 10.

[0119] If the engaging portion 201 of the carrier 200 fails to engage with the tooth groove 111a of the ratchet 11 of the first rotating mechanism 1 when the carrier 200 enters the first conveying channel 10 due to an unexpected condition such as the carrier 200 tilting, an abnormal state will occur in which the material is stuck and cannot be conveyed further. If the conveying device 100 fails to promptly identify this abnormal state and remind the operator to deal with it, subsequent carriers 200 will be continuously conveyed toward the first conveying channel 10, resulting in an accumulation of carriers 200, and may even push the carrier 200 toward the ratchet 11, causing the carrier 200 and the ratchet 11 to get stuck or wear each other, making the abnormal state more serious and causing damage to the carrier 200, the battery carried in the carrier 200, or the conveying device 100.

[0120] The conveying device 100 of the present embodiment includes an alarm mechanism 3 disposed on the outer periphery of the ratchet 11. If the engaging portion 201 of the carrier 200 fails to engage with the tooth groove 111a, the carrier 200, pushed by the ratchet 11, moves toward the alarm mechanism 3 and contacts the alarm mechanism 3, thereby triggering the alarm mechanism 3 to emit a first alarm signal. Therefore, the conveying device 100 can promptly identify abnormal conveying conditions and promptly emit an alarm signal to remind the operator to promptly address the abnormal condition, thereby improving the stability of the conveying process and reducing the possibility of damage to the carrier 200, the battery carried in the carrier 200, or the conveying device 100.

[0121] In some embodiments of the present application, the first alarm signal includes an alarm signal and / or a shutdown signal.

[0122] The first alarm signal may, for example, include an alarm signal for prompting, so that the operator can promptly discover abnormal conditions in transportation based on the alarm signal, and promptly handle the abnormal conditions and resume transportation as soon as possible, thereby ensuring the stability of the transportation process and improving transportation efficiency.

[0123] The alarm signals include but are not limited to visual alarm signals such as flashing indicator lights, auditory alarm signals such as sound alarms, or pop-up alarm abnormality prompts in the host computer.

[0124] In addition, the first alarm signal may also include a shutdown signal, so that the conveying device 100 can stop the operation of the conveying device 100 according to the shutdown signal and wait for the operator to deal with the abnormal state, thereby reducing the occurrence of adverse conditions such as accumulation of the carriers 200 due to the continuous operation of the conveying device 100, avoiding the aggravation of the abnormal state, and also improving the safety of the operator when dealing with the abnormality.

[0125] In some embodiments of the present application, the ratchet 11 includes a tooth tip 111 b on its outer circumference adjacent to the tooth groove 111 a , and the tooth tip 111 b is used to push the carrier 200 , whose engagement portion 201 is not engaged with the tooth groove 111 a , toward the alarm mechanism 3 .

[0126] The tooth tip 111b protrudes away from the axis of the ratchet 11 and is located on the downstream side of the tooth groove 111a along the conveying direction of the carrier 200. The downstream side refers to the material removal direction of the carrier 200.

[0127] When the engaging portion 201 of the carrier 200 fails to engage with the tooth groove 111a, the ratchet 11 will continue to rotate, so that the protruding tooth tip 111b will contact the carrier 200, and as the ratchet 11 rotates, the carrier 200 will be pushed in the direction away from the first rotating mechanism 1, and the alarm mechanism 3 is located on the periphery of the ratchet 11. Therefore, the carrier 200 with stuck material will move toward the alarm mechanism 3 under the push of the tooth tip 111b and contact the alarm mechanism 3, so that the alarm mechanism 3 recognizes that the transportation is abnormal and sends a first alarm signal.

[0128] In addition, since the carrier 200 that is stuck will be pushed away from the first rotating mechanism 1 by the tooth tip 111b, the possibility of the carrier 200 always staying in the stuck position and causing the first rotating mechanism 1 to be stuck and damaged can be reduced, thereby improving the reliability of the conveying device 100.

[0129] In the embodiment of the present application, the minimum distance between the tooth tip 111b and the alarm mechanism 3 is smaller than the minimum equivalent diameter of the carrier 200. In this way, it can be ensured that the carrier 200 can come into contact with the alarm mechanism 3 under the push of the tooth tip 111b, thereby smoothly triggering the alarm mechanism 3.

[0130] Next, the specific structure of the alarm mechanism 3 will be described in detail.

[0131] In some embodiments of the present application, Figure 1 、 Figure 2 and Figure 4 As shown, the alarm mechanism 3 includes a first rib 31, a trigger lever 32, and a material jam sensor 33. The first rib 31 is disposed on the outer periphery of the ratchet 11 and is rotatable relative to the outer periphery of the ratchet 11. The first rib 31 and the ratchet 11 form a first conveying channel 10 between the first rib 31 and the ratchet 11. The trigger lever 32 is located on the side of the first rib 31 facing away from the ratchet 11 and is fixedly connected to the first rib 31. The material jam sensor 33 is spaced apart from the trigger lever 32. When the material jam sensor 33 detects a change in its relative position to the trigger lever 32, it issues the first alarm signal.

[0132] For example, the first retaining edge 31 is generally plate-shaped and is provided on a frame (not shown) via a rotating shaft in a manner that allows it to rotate relative to the outer periphery of the ratchet 11 , and the material jamming sensor 33 is fixedly connected to the frame.

[0133] The jam sensor 33 may be, for example, a proximity sensor capable of detecting changes in the position of a trigger lever 32 spaced apart from it, and the proximity sensor is always positioned stationary. Under normal circumstances, the first rib 31 remains stationary in its initial position. However, when the carrier 200, pushed by the tooth tip 111b, contacts the alarm mechanism 3, it contacts the first rib 31 of the alarm mechanism 3. Force is applied to the first rib 31, causing it to rotate relative to the outer periphery of the ratchet 11. Since the trigger lever 32 is fixedly connected to the first rib 31, the trigger lever 32 rotates with the first rib 31. At this point, the proximity sensor detects a change in relative position with the trigger lever 32, thereby identifying an abnormal conveying state and issuing a first alarm signal.

[0134] Specifically, in the embodiments of the present application, Figure 2As shown, the proximity sensors are spaced below the trigger rod 32 along the height direction. When the alarm mechanism 3 is in its initial state, the proximity sensors and the trigger rod 32 are arranged parallel to each other and extend in the same direction. That is, in a projection plane perpendicular to the height direction, the angle between the proximity sensors and the trigger rod 32 is zero. When the carrier 200 contacts the first rib 31, it pushes the first rib 31 to rotate away from the first rotating mechanism 1, driving the trigger rod 32 to rotate toward the first rotating mechanism 1. This causes the relative position between the trigger rod 32 and the proximity sensors to change. That is, in a projection plane perpendicular to the height direction, the angle between the proximity sensors and the trigger rod 32 changes, causing the proximity sensors to detect a conveying anomaly and issue a first alarm signal.

[0135] Those skilled in the art will appreciate that in other embodiments, the arrangement of the trigger lever 32 and the material jam sensor 33 may differ from that of the present application. As long as the material jam sensor 33 detects a change in the relative position between the trigger lever 32 and the material jam sensor 33 compared to the initial position, it can be determined that the carrier 200 has failed to engage with the tooth groove 111a, thereby causing an abnormal material jam. Furthermore, the material jam sensor 33 need not necessarily be a proximity sensor; it may be any other suitable sensor capable of detecting a change in the relative position between the material jam sensor 33 and the trigger lever 32.

[0136] The alarm mechanism 3 of the embodiment of the present application has a simple structure, ingenious design, high sensitivity, and can timely identify abnormal transportation conditions in an automated manner, thereby improving the reliability of the transportation device 100.

[0137] In some embodiments of the present application, Figure 2 and Figure 4 As shown, the first rib 31 includes a straight portion 311 and a curved portion 312 connected to each other. The curved portion 312 is provided on the outer periphery of the ratchet 11, and the straight portion 311 extends away from the ratchet 11. The conveying device 100 also includes a baffle 4, which is spaced apart and located on opposite sides of the straight portion 311. The baffle 4 and the straight portion 311 form a feed channel 30 between the baffle 4 and the feed channel 30. The feed channel 30 is connected to the first conveying channel 10. The carrier 200 is conveyed to the ratchet 11 via the feed channel 30, can engage with the tooth groove 111a of the ratchet teeth 111, and flow through the first conveying channel 10 as the first rotating mechanism 1 rotates.

[0138] The curved portion 312 is generally semicircular in shape and is arranged on the outer periphery of the ratchet 11, forming a first conveying channel 10 between the ratchet 11. In this way, whether the carrier 200 is stuck during feeding or during the conveying process of the first conveying channel 10, it can contact the curved portion 312 of the first retaining edge 31 under the push of the tooth tip 111b, thereby triggering the alarm mechanism 3 to send a first alarm signal.

[0139] The baffle 4 is generally flat and positioned opposite the straight portion 311 of the first retaining edge 31, forming a feed channel 30 therebetween. Because the carrier 200 flows through the feed channel 30 before flowing into the first conveying channel 10, the carrier 200 is conveyed to the first rotating mechanism 1 along a prescribed feed path, reducing the possibility of the carrier 200 being misaligned during feeding and unable to engage with the tooth grooves 111a of the ratchet teeth 111, thereby causing material jamming.

[0140] In some embodiments of the present application, the trigger rod 32 is connected to the connection position of the straight portion 311 and the curved portion 312 and is located outside the feeding channel 30 .

[0141] Therefore, no matter whether the trigger rod 32 remains stationary in the normal conveying state or rotates in the abnormal state of material jamming, the trigger rod 32 will not interfere with the carrier 200 conveyed in the feeding channel 30 and the first conveying channel 10, as well as the batteries carried in the carrier 200, thereby ensuring the stability of the conveying process and reducing the possibility of damage to the carrier 200 and the batteries carried in the carrier 200 due to interference collision.

[0142] In some embodiments of the present application, the conveying device 100 includes a height detection sensor 5 for detecting the height of the batteries carried in the carrier 200. The height detection sensor 5 is disposed on one side of the feed channel 30 near the feed port 301. When the height of the batteries flowing into the feed channel 30 exceeds a preset height, the height detection sensor 5 issues a second alarm signal.

[0143] When the battery is carried in the carrier 200, if it is placed at an angle or the battery model is wrong, the height of the battery may change. If this abnormal height condition is not identified in time during the transportation of the battery, it may cause the subsequent processing to fail.

[0144] Therefore, the conveying device 100 of the embodiment of the present application further includes a height detection sensor 5 disposed near the feed port 301, enabling the conveying device 100 to promptly identify abnormal battery height conditions. Before the carrier 200 enters the first conveying channel 10 and while being conveyed within the feed channel 30, the height detection sensor 5 detects the height of the batteries carried within the carrier 200 to determine whether the batteries are excessively high or abnormally high due to tilted placement. If abnormal battery height is detected, a second alarm signal is issued to promptly alert the operator to address the abnormal condition.

[0145] Specifically, the height detection sensor 5 can be fixed on a rack, and can be a laser sensor, for example. When the battery is placed at an angle or exceeds a preset height, the top of the battery will exceed the laser sensor in the height direction, so that the laser beam emitted by the laser sensor will illuminate the extra-high part of the battery and reflect in advance, thereby identifying that the height of the battery is abnormal.

[0146] Of course, those skilled in the art should understand that the embodiment of the present application does not specifically limit the type of the height detection sensor 5, and any other suitable sensor may also be used.

[0147] Exemplarily, the second alarm signal may include a prompt alarm signal, such as an auditory alarm signal, a visual alarm signal, etc., for prompting an operator that a highly abnormal state has occurred.

[0148] As another example, the second alarm signal may further include a stop signal. The conveying device 100 stops the operation of the conveying device 100 according to the stop signal sent by the height detection sensor 5 and waits for the operator to handle the abnormal state.

[0149] In some embodiments of the present application, although not shown in the figures, the conveying device 100 includes a rotation drive device, which is used to drive the first rotating mechanism 1 to rotate. The first rotating mechanism 1 is connected to the output end of the rotation drive device via a coupling 6. The coupling 6 is disconnected from the output end of the rotation drive device in response to the first alarm signal, thereby stopping the rotation of the first rotating mechanism 1.

[0150] Thus, the first rotating mechanism 1 can be rotated in an automated manner by being driven by the rotary drive device, thereby driving the carrier 200 engaged with the tooth groove 111 a to be transported along a predetermined direction.

[0151] Furthermore, the coupling 6 transmits power from the output end of the rotation drive device to the first rotating mechanism 1, thereby ensuring smoother rotation of the first rotating mechanism 1. Furthermore, upon receiving a first alarm signal, the coupling 6 can disconnect from the output end of the rotation drive device, thereby stopping the rotation of the first rotating mechanism 1 and the entire conveying device 100, making it easier for operators to address abnormal conditions.

[0152] The coupling 6 may be, for example, a commercially available safety coupling, so that it can be tripped or slipped to disconnect from the output end of the rotary drive device after receiving the first alarm signal.

[0153] The rotary drive device includes but is not limited to a motor and a servo motor.

[0154] In some embodiments of the present application, Figures 1 to 3 As shown, the conveying device 100 includes a second side 7, which is arranged on the outer periphery of the turntable 21 and forms a second conveying channel 20 between the second side 7 and the turntable 21. The second conveying channel 20 is connected to the first conveying channel 10. Along the conveying direction of the carrier 200, the second conveying channel 20 is located downstream of the first conveying channel 10.

[0155] Downstream refers to the direction of removal of the carrier 200 , that is, the carrier 200 first flows through the first conveying channel 10 as the first rotating mechanism 1 rotates, and then flows through the second conveying channel 20 as the second rotating mechanism 2 rotates.

[0156] The second rib 7 is generally in the shape of an arcuate plate and can be fixedly connected to the frame, for example. When the carrier 200 is rotated and transported by the second rotating mechanism 2, it can be located between the groove 211 and the second rib 7, thereby being transported along a prescribed conveying route. This reduces the possibility of the carrier 200 shifting during transport, making the transport of the carrier 200 more reliable.

[0157] In an embodiment of the present application, the carrier 200 is transported by rotating the first rotating mechanism 1 and the second rotating mechanism 2. The first conveying channel 10 and the second conveying channel 20 are both arc-shaped, and the carrier 200 is transported along the arc-shaped conveying path. Compared with the conventional conveying device, which is a conveying path arranged in a straight line in the same direction, the conveying device 100 of the embodiment of the present application occupies a smaller space, which is conducive to improving the space utilization rate of factory workshops, etc.

[0158] In some embodiments of the present application, the conveying device 100 also includes a color detection sensor 8, which is arranged in the second conveying channel 20 and is used to detect the color of the top surface of the battery. When the color detection sensor 8 detects that the color of the top surface of the battery is not a preset color, the color detection sensor 8 sends a third alarm signal.

[0159] When batteries are placed in the carrier 200, they must be oriented correctly. For example, when a cylindrical battery is being processed, the positive electrode must be placed upward within the carrier 200. If the battery orientation is incorrect and this is not detected during transport, subsequent processing may fail.

[0160] Therefore, the conveyor 100 also includes a color detection sensor 8, which enables the conveyor 100 to promptly identify abnormal battery placement orientations. For example, the positive and negative electrodes of cylindrical batteries can be coated with different colors. The conveyor 100 can use the color detection sensor 8 to detect the color of the top surface of the battery held within the carrier 200, thereby determining whether the battery is placed within the carrier 200 in the specified orientation.

[0161] Those skilled in the art will appreciate that this application uses cylindrical batteries as an example for explanation and does not limit the battery type to cylindrical batteries. When the battery supported by the carrier 200 is of other shapes, each surface of the battery can be coated with a color, and the color detection sensor 8 can be used to identify whether the surface to be processed is placed upward within the carrier 200.

[0162] Specifically, if Figures 1 to 3 As shown, the color detection sensor 8 is arranged on a bracket 71 fixedly connected to the second rib 7 and is located above the second conveying channel 20 in the height direction, so that it can effectively detect the color of the top surface of the battery flowing through the second conveying channel 20.

[0163] The color detection sensor 8 is arranged in the second conveying channel 20 to avoid interference with the alarm mechanism 3 of the first conveying channel 10 and the height detection sensor 5 arranged in the feeding channel 30 , thereby improving the detection reliability of the color detection sensor 8 .

[0164] Of course, those skilled in the art should understand that the embodiment of the present application does not limit the specific location of the color detection sensor 8, as long as it can detect the color of the top surface of the conveyed battery.

[0165] If the color detection sensor 8 detects that the color of the top surface of the battery is abnormal, it can be identified that the placement direction of the battery is abnormal. At this time, the color detection sensor 8 will issue a third alarm signal to promptly remind the operator to pay attention to the incorrect placement direction of the battery and to deal with the abnormal state in a timely manner.

[0166] Exemplarily, the third alarm signal may include a prompt alarm signal, such as an auditory alarm signal, a visual alarm signal, etc., for prompting the operator that an abnormal placement direction state has occurred.

[0167] As another example, the third alarm signal may further include a stop signal. The conveying device 100 stops the operation of the conveying device 100 according to the stop signal sent by the color detection sensor 8 and waits for the operator to handle the abnormal state.

[0168] In some embodiments of the present application, Figures 1 to 3 and Figure 5 As shown, the conveying device 100 further includes a blocking mechanism 9, which is disposed in the feed channel 30. The blocking mechanism 9 includes a blocking drive 91 and a block 92. The block 92 is driven by the blocking drive 91 to rotate between a first position and a second position. When the block 92 is in the first position, the feed channel 30 is connected to the first conveying channel 10, allowing the carrier 200 to flow into the first conveying channel 10. When the block 92 is in the second position, it blocks the carrier 200 from flowing into the first conveying channel 10. When the first alarm signal is issued, the block 92 is driven by the blocking drive 91 to rotate to the second position.

[0169] The blocking mechanism 9 can be fixedly connected to the frame, for example, and includes a blocking drive 91 and a block 92. The block 92 can be rotatably connected to the blocking drive 91 via a rotating shaft, for example. The baffle 4 is provided with an escape opening 41, through which the block 92 can be driven by the blocking drive 91 to rotate between a first position for releasing the block and a second position for blocking.

[0170] When the alarm mechanism 3 identifies the abnormal state of material jamming in the conveying device 100 and issues a first alarm signal, the block 92 can be rotated to the second position under the drive of the blocking drive device 91, thereby blocking the connection between the feed channel 30 and the first conveying channel 10, so that the carrier 200 conveyed by the feed channel 30 cannot continue to be conveyed to the first conveying channel 10. In this way, before the operator handles the abnormal state, no new carriers 200 will flow into the first conveying channel 10, reducing the possibility of the carriers 200 accumulating in the first conveying channel 10 and causing the abnormal state to worsen.

[0171] In some embodiments of the present application, after the second alarm signal is issued, the stopper 92 is driven by the blocking driving device 91 to rotate to the second position.

[0172] Therefore, when the height detection sensor 5 recognizes that the battery carried in the carrier 200 is in an abnormal state with an abnormal height and issues a second alarm signal, the block 92 can be rotated to the second position under the drive of the blocking drive device 91, thereby blocking the connection between the feed channel 30 and the first conveying channel 10, so that the carrier 200 conveyed by the feed channel 30 cannot continue to be conveyed to the first conveying channel 10, thereby making it easier for the operator to deal with the current abnormal state.

[0173] In some embodiments of the present application, after the third alarm signal is issued, the stopper 92 is driven by the blocking driving device 91 to rotate to the second position.

[0174] Therefore, when the color detection sensor 8 recognizes that the battery carried in the carrier 200 is in an abnormal state of being placed in the wrong direction and issues a second alarm signal, the block 92 can be rotated to the second position under the drive of the blocking drive device 91, thereby blocking the connection between the feed channel 30 and the first conveying channel 10, so that the carrier 200 conveyed by the feed channel 30 cannot continue to be conveyed to the first conveying channel 10, thereby making it easier for the operator to deal with the current abnormal state.

[0175] In some embodiments of the present application, the battery includes a cylindrical battery, and the carrier 200 includes a cup for supporting the cylindrical battery.

[0176] Therefore, the conveying device 100 can convey the cylindrical batteries carried in the cup, and can promptly identify whether the cup carrying the cylindrical batteries has abnormal conditions such as material jamming, battery tilting, or reversed battery polarity during the conveying process, which is conducive to improving the stability of conveying.

[0177] The present application provides a conveying method, using a conveying device 100 to convey a carrier 200 carrying batteries to a specified position, the conveying device 100 includes a first rotating mechanism 1, a second rotating mechanism 2 and an alarm mechanism 3, the first rotating mechanism 1 includes a ratchet 11 configured to be rotatable and having a plurality of ratchet teeth 111, the second rotating mechanism 2 includes a turntable 21 configured to be rotatable and having a plurality of grooves 211, and the carrier 200 has an engaging portion 201 for engaging with the tooth grooves 111a of the ratchet teeth 111 and the grooves 211 of the turntable 21. Figure 7 As shown, the delivery methods include:

[0178] S100: a feeding step, wherein the carrier carrying the batteries flows toward the first rotating mechanism.

[0179] S200: A first engagement step, engaging the engagement portion of the carrier with the tooth groove of the ratchet.

[0180] S300: A first conveying step, wherein the carrier is conveyed to the second rotating mechanism by the rotation of the ratchet wheel of the first rotating mechanism.

[0181] S400: a second engagement step, engaging the engagement portion of the carrier with the groove of the turntable.

[0182] S500: A second conveying step, wherein the carrier is conveyed to a predetermined position by the rotation of the turntable of the second rotating mechanism.

[0183] In the first engagement step, if the engagement portion 201 of the carrier 200 fails to engage with the tooth groove 111 a of the ratchet 111 , the carrier 200 contacts the alarm mechanism 3 under the push of the ratchet 11 , and the alarm mechanism 3 issues a first alarm signal.

[0184] Thus, by using the conveying device 100, the carrier 200 can be conveyed in a simple and automated manner, and the possibility of the carrier 200 getting stuck can be reduced. In addition, if a jam occurs, the alarm mechanism 3 can promptly identify the abnormal state of the jam and issue a first alarm signal to remind the operator to promptly handle the abnormal state, thereby improving the stability of the conveying process.

[0185] The first alarm signal may include, for example, an alarm signal and / or a shutdown signal.

[0186] In some embodiments of the present application, the conveying device 100 includes a rotary drive device, which is used to drive the first rotary mechanism 1 to rotate. The first rotary mechanism 1 is connected to the output end of the rotary drive device via a coupling 6. Figure 8 As shown, the delivery method further includes:

[0187] S600: a shutdown step, in which the coupling is disconnected from the output end of the rotation drive device according to the first alarm signal, thereby stopping the first rotating mechanism from rotating.

[0188] S700: Alarm step: the conveying device issues an alarm notification according to the first alarm signal.

[0189] Therefore, when the alarm mechanism 3 identifies that the conveying device 100 is in an abnormal state of material jamming, it can stop the machine in time to avoid the abnormal state from becoming serious, and can issue an alarm notification to remind the operator to deal with the abnormal state.

[0190] In some embodiments of the present application, the conveying device 100 includes a height detection sensor 5. Figure 9 As shown, before the first engagement step, the conveying method further includes:

[0191] S800: Height detection step, determining whether the height of the battery carried in the carrier exceeds a preset height. If it does not exceed the preset height, the process proceeds to the first engagement step. If it exceeds the preset height, the height detection sensor issues a second alarm signal.

[0192] Thus, the conveying device 100 can detect the height of the battery and promptly identify whether the battery is too high or tilted, and when the height of the battery is abnormal, promptly send out a second alarm signal to remind the operator to deal with the abnormal state.

[0193] The second alarm signal may include, for example, an alarm signal and / or a shutdown signal.

[0194] In some embodiments of the present application, the delivery device 100 includes a color detection sensor 8. Figure 10 As shown, the delivery methods include:

[0195] S900: a color detection step, determining whether the color of the top surface of the battery carried in the carrier is a preset color. If it is the preset color, the carrier is continued to be conveyed. If it is not the preset color, the color detection sensor sends a third alarm signal.

[0196] Therefore, the conveying device 100 can also detect the placement direction of the battery to promptly identify whether the placement direction of the battery is incorrect, and when the placement direction of the battery is abnormal, promptly issue a third alarm signal to remind the operator to deal with the abnormal state.

[0197] The third alarm signal may include, for example, a warning signal and / or a shutdown signal.

[0198] In some embodiments of the present application, the conveying device 100 further includes a blocking mechanism 9, which includes a blocking drive device 91 and a block 92. The block 92 can rotate between a first position and a second position under the drive of the blocking drive device 91. The block 92 is in the first position to avoid the carrier 200. The block 92 is in the second position to block the conveyance of the carrier 200. Figure 11 As shown, the delivery methods include:

[0199] S801: a first blocking step, when a first alarm signal is issued, the blocking block is driven by the blocking driving device to rotate to the second position.

[0200] Therefore, when the conveying device encounters an abnormal state of material jamming, the blocking mechanism 9 can prevent the carrier 200 in the feeding channel 30 from continuing to be conveyed to the first conveying channel 10, thereby avoiding the aggravation of the abnormal state.

[0201] In some embodiments of the present application, the delivery method includes:

[0202] S802: A second blocking step, when the second alarm signal is issued, the block is driven by the blocking drive device to rotate to the second position.

[0203] Therefore, when the carrier 200 carrying batteries is in a highly abnormal state, the blocking mechanism 9 can prevent the carrier 200 in the feeding channel 30 from continuing to be conveyed to the first conveying channel 10, making it easier for operators to handle the current abnormal state.

[0204] In some embodiments of the present application, the delivery method further comprises:

[0205] S803: The third blocking step, when the third alarm signal is issued, the blocking block is driven by the blocking driving device to rotate to the second position.

[0206] Therefore, when the carrier 200 carrying the battery is in an abnormal state of being placed in the wrong direction, the blocking mechanism 9 can prevent the carrier 200 in the feeding channel 30 from continuing to be conveyed to the first conveying channel 10, making it easier for the operator to handle the current abnormal state.

[0207] The present application also provides a battery production line, comprising a carrier conveyor line and a conveying device 100 according to any of the above embodiments. The carrier conveyor line is used to convey carriers 200. The carrier conveyor line is connected to the first conveying channel 10 of the conveying device 100. The battery comprises a cylindrical battery, and the carrier 200 comprises a tray for holding the cylindrical battery.

[0208] In the battery production line provided in the embodiment of the present application, the cylindrical battery is placed in a tray in the front workstation, and the tray containing the cylindrical battery is transported to the conveying device 100 via the carrier conveying line, and then the tray containing the cylindrical battery is transported to the subsequent workstation via the conveying device 100.

[0209] Exemplarily, the carrier conveying line may be a conveyor belt, for example, a belt or other belt-like object, or a plurality of rollers arranged in parallel, or a plurality of chains or a double-speed chain, etc.

[0210] In this way, the conveying of the trays carrying cylindrical batteries can be achieved in an automated manner, and the possibility of the trays getting stuck can be reduced. In addition, if the trays get stuck, the battery height is abnormal, or the battery placement direction is abnormal, the conveying device 100 can promptly identify the abnormal state and remind the operator to deal with the abnormal state in a timely manner, thereby improving the stability of the conveying process.

[0211] In some embodiments of the present application, the battery production line further includes a welding station, which is used to weld the batteries conveyed by the conveying device 100 .

[0212] In this way, the cylindrical batteries can be transported to the welding station for welding in a normal, orderly and efficient manner.

[0213] Below, some specific examples of embodiments of the present application are described with reference to the accompanying drawings.

[0214] As a specific example, the conveying device 100 includes a feed turntable (first rotating mechanism 1), a transition turntable (second rotating mechanism 2), a jam alarm mechanism (alarm mechanism 3), a laser sensor (height detection sensor 5), a color sensor (color detection sensor 8), and a stop cylinder (blocking mechanism 9). The toothed disc (ratchet 11) of the feed turntable and the toothed disc (rotary disc 21) of the transition turntable work closely together to transport the battery cells (batteries) in the feed, effectively reducing the possibility of jams.

[0215] The jam alarm mechanism is fixed to one side of the feed turntable and includes a rib (first rib 31), a torsion beam (trigger rod 32), and a proximity sensor (stuck sensor 33). When battery cells are fed, if the battery cup and the feed turntable become stuck, the battery cup (supporting member 200) will be pushed toward the rib by the feed turntable, and the rib will move outward, driving the torsion beam at one end inside to move outward, and the other end of the torsion beam to move inward away from the proximity sensor, thereby triggering the proximity sensor alarm. In addition, the torque converter (coupling 6) on the feed turntable and the transition turntable will be disengaged, causing the turntable to stop rotating.

[0216] The laser sensor is fixed on the other side of the feed port. When the feeding state of the cylindrical battery cell is abnormal (the battery cell is tilted / the battery cell is too high), the edge of the battery cell top cover is too high and will touch the micro-motion sensor to cause an alarm, reminding that the cylindrical battery cell is too high. The color sensor is fixed on one side of the transfer turntable to detect the polarity of the cylindrical battery. If the polarity of the cylindrical battery is reversed, the color sensor alarm will remind you that the polarity is reversed. The stop cylinder is fixed on the same side of the laser sensor. The stop cylinder includes a cylinder (blocking drive device 91) and a block (block 92). When the feeding of the cylindrical battery cell is abnormal, the stop cylinder is used to block the battery cell at the previous workstation.

[0217] In this way, the conveying device 100, through the cooperation of the double turntable structure and the detection of various sensors, enables the cylindrical battery cells to flow into the welding station for welding operations in a normal state, efficiently and orderly, thereby improving the stability of transportation.
