Description

Technical Field

[0001] The present application relates to the technical field of batteries, and particularly to a conveying device and a conveying system. Background Art

[0002] In the production process of batteries, in order to facilitate the conveyance of electrode assemblies between different workstations, a conveying device is usually used for conveyance. Since different workstations are equipped with machines performing different operations, in order to cooperate with different machines, the conveying path of the conveying device is not necessarily all set to be straight, and there are also turning areas. The conveyed electrode assemblies are prone to collision when passing through the turning areas, resulting in damage to the conveyed electrode assemblies, thereby affecting the quality of the electrode assemblies. Summary of the Invention

[0003] In view of the above problems, the present application provides a conveying device and a conveying system, which can reduce the problem that the electrode assemblies to be conveyed are damaged due to collision in the turning areas.

[0004] In a first aspect, the present application provides a conveying device for conveying electrode assemblies. The conveying device includes a bracket, a first conveying member, a second conveying member, and a control mechanism. The bracket has a conveying channel, and the right-angle turning area of the conveying channel is divided into a first section and a second section along the diagonal; the first conveying member is arranged in the first section; the second conveying member is arranged in the second section, and the second conveying member and the first conveying member jointly support and convey the workpiece to be conveyed; the control mechanism is used to detect whether the workpiece to be conveyed enters or leaves the right-angle turning area, and according to the detection signal, control the rotation speed and rotation direction of the first conveying member and the second conveying member;

[0005] When the workpiece to be conveyed enters the right-angle turning area, the first conveying member rotates at a first preset speed, and jointly decelerates with the second conveying member to convey the workpiece to be conveyed to the positioning area;

[0006] When the workpiece to be conveyed leaves the right-angle turning area, the first conveying member rotates at a second preset speed, and jointly accelerates with the second conveying member to output the workpiece to be conveyed from the right-angle turning area, wherein the first preset speed is less than the second preset speed.

[0007] In the technical solution of the embodiment of the present application, the control mechanism is used to control the running speeds of the first conveying member and the second conveying member, so as to slow down the speed of the electrode assembly to be conveyed that has just entered the right-angle turning area, and convey it slowly to the positioning area. Subsequently, the first conveying member and the second conveying member are used to accelerate and output it from the right-angle turning area. In this way, the electrode assemblies to be conveyed can pass through the right-angle turning area smoothly, reducing the probability that the electrode assemblies to be conveyed collide with the bracket due to too high a speed when passing through the right-angle turning area, resulting in damage to the electrode assemblies to be conveyed, and protecting the electrode assemblies while conveying them.

[0008] In some embodiments, the control mechanism includes a first detector, a second detector, and a driving member. The first detector is disposed in the first section and is used to detect whether the item to be conveyed enters the first section. The second detector is disposed in the second section and is used to detect whether the item to be conveyed enters the second section.

[0009] Both the first detector and the second detector are electrically connected to the driving member and send signals to the driving member. The driving member controls the rotation speed and rotation direction of the first conveyor and the second conveyor according to the received signals.

[0010] In this way, by setting the first detector and the second detector to detect in real time whether the item to be conveyed enters the first section and the second section, and sending the detected signals to the driving member at any time, the driving member can then control the rotation speed and rotation direction of the first conveyor and the second conveyor in real time, so as to convey the item to be conveyed at a preset speed, improving the conveying efficiency and conveying stability of the item to be conveyed.

[0011] In some embodiments, the number of the first conveyors is multiple. All the first conveyors are arranged at intervals along the first direction and are linked, and one of the first conveyors is connected to the driving member.

[0012] When the item to be conveyed enters the right-angle turning area, all the first conveyors rotate forward around the second direction. When the item to be conveyed leaves the right-angle turning area, the first conveyors rotate backward around the second direction, and the second direction intersects with the first direction.

[0013] In this way, by setting all the first conveyors to be linked, there is no need to set multiple driving members to drive different first conveyors respectively, reducing the number of driving members to be set, simplifying the structure of the conveying device, and reducing the production cost of the conveying device. In addition, setting all the first conveyors to be linked is beneficial to controlling the running speed between all the first conveyors.

[0014] In some embodiments, when the item to be conveyed enters the right-angle turning area, the second conveyor rotates backward around the first direction at a third preset speed. When the item to be conveyed leaves the right-angle turning area, the second conveyor rotates forward around the first direction at a fourth preset speed, where the third preset speed is less than the fourth preset speed.

[0015] With such a setting, by adjusting the rotation direction and rotation speed of the second conveyor to cooperate with the first conveyor, the conveying posture of the item to be conveyed can be jointly adjusted to protect the item to be conveyed and reduce the probability that the conveying posture of the item to be conveyed changes due to too fast conveying speed and then collides with the bracket.

[0016] In some embodiments, the number of the second conveyors is multiple. All the second conveyors are arranged at intervals along the second direction and are linked, and one of the second conveyors is connected to the driving member.

[0017] In this way, all the second conveying members are set to be linked, eliminating the need to set multiple driving members to drive different second conveying members respectively. This reduces the number of driving members to be set, simplifies the structure of the conveying device, and lowers the production cost of the conveying device. Moreover, setting all the second conveying members to be linked is conducive to controlling the running speeds of all the second conveying members.

[0018] In some embodiments, the conveying device further includes a plurality of transmission members. One transmission member is shared between two adjacent first conveying members, and they are connected by transmission through the transmission member.

[0019] One transmission member is also shared between two adjacent second conveying members, and they are connected by transmission through the transmission member.

[0020] With such a setting, during actual operation, if at least one of the first conveying members or the second conveying members is damaged, it is convenient for the user to quickly find and repair it. Moreover, compared with using different linkage components to connect two adjacent first conveying members and two adjacent second conveying members, using a single transmission member only requires producing one type of mold for preparing the transmission member, reducing the production quantity of the mold.

[0021] In some embodiments, the connection between the transmission member and the first conveying member is detachable, and the connection between the transmission member and the second conveying member is also detachable.

[0022] When any one of the transmission member, the first conveying member, and the second conveying member is damaged, only the damaged component needs to be replaced, reducing the maintenance cost compared with replacing the whole.

[0023] In some embodiments, the driving member includes a first sub-member and a second sub-member, and the control mechanism further includes a first control member and a second control member. The first control member, the second control member, the first sub-member, and the second sub-member are all electrically connected to the first detector and the second detector. The first control member is arranged in the first section, and the first control member controls the first sub-member according to the signal sent by the first detector to control the first conveying member. The second control member also controls the second sub-member according to the signal sent by the first detector to control the second conveying member.

[0024] The second control member is arranged in the second section. The first control member controls the first sub-member according to the signal sent by the first detector to control the first conveying member, and the second control member controls the second sub-member according to the signal sent by the second detector to control the second conveying member.

[0025] The above setting improves the accuracy of the cooperation between the first conveying member and the second conveying member, and can output the workpiece to be conveyed from the right-angle turning area relatively quickly.

[0026] In some embodiments, the support is divided into a first layer and a second layer in the vertical direction. Both the first layer and the second layer are provided with a conveying channel. The conveying direction of the first layer is opposite to that of the second layer. One of the first layer and the second layer is used to convey the piece to be conveyed supported by the supporting piece, and the other is used to output the supporting piece without carrying the piece to be conveyed.

[0027] In this way, two layers are arranged on the support in the vertical direction, which reduces the space used for recycling the supporting piece while realizing the semi-automatic recycling of the supporting piece.

[0028] In some embodiments, the support is convexly provided with an anti-collision part, and the anti-collision part is arranged at the edge of the right-angle turning area.

[0029] During the process that the piece to be conveyed passes through the right-angle turning area, if the piece to be conveyed has a tendency to move out of the support, the anti-collision part can block the piece to be conveyed, limit the piece to be conveyed within the conveying channel, reduce the probability of it falling from the support, and protect the piece to be conveyed.

[0030] In some embodiments, both the first conveying piece and the second conveying piece are detachably mounted on the support.

[0031] When the first conveying piece and the second conveying piece are damaged, it is convenient to disassemble and assemble the damaged parts to replace them with new parts, reducing the maintenance cost.

[0032] In a second aspect, the present application provides a conveying system, which includes a supporting piece and the conveying device in the above embodiments. The supporting piece is used to support the piece to be conveyed and is conveyed by the conveying device.

[0033] The above description is only an overview of the technical solution of the present application. In order to be able to understand the technical means of the present application more clearly, it can be implemented according to the content of the specification.

[0049] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power stations, but also widely used in electric transportation tools such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0050] The electrode assembly is one of the important components of the battery device. During the preparation process of the battery device, a conveying device is generally used to convey the electrode assembly between different workstations. And for the convenience of layout to adapt to the executing components at different workstations, the equipped conveying device generally has a right-angle turning area. And the electrode assembly is prone to collision and damage when passing through the right-angle turning area.

[0051] To solve the problem that the electrode assembly is easily damaged when passing through the right-angle turning area, an embodiment of the present application provides a conveying device, which includes a bracket, a first conveying member, a second conveying member and a control mechanism. The conveying channel of the bracket has a right-angle turning area, which has a first section and a second section. The first conveying member is arranged in the first section, and the second conveying member is arranged in the second section. The control mechanism controls the first conveying member and the second conveying member to decelerate together to slowly convey the workpiece to be conveyed to the positioning area. After the workpiece to be conveyed adjusts its posture in the positioning area, the control mechanism controls the first conveying member and the second conveying member to accelerate together to output the workpiece to be conveyed from the right-angle turning area, so as to output the workpiece to be conveyed from the right-angle turning area on the basis of protecting the workpiece to be conveyed.

[0052] The conveying device disclosed in the embodiment of the present application can be but is not limited to being used in a battery conveying line, for example, a battery conveying line that needs to detect whether a battery or a tray is in place. Of course, those skilled in the art should understand that the conveying device provided in the embodiment of the present application can not only be a battery conveying line, but also a conveying line for conveying other workpieces.

[0053] Please refer to Figures 1 to 4 , some embodiments of the present application provide a conveying device 1000 for conveying an electrode assembly. The conveying device 1000 includes a bracket 100, a first conveying member 200, a second conveying member 300 and a control mechanism 400. The bracket 100 has a conveying channel 10, and the right-angle turning area 11 of the conveying channel 10 is divided into a first section 111 and a second section 112 along the diagonal; the first conveying member 200 is arranged in the first section 111; the second conveying member 300 is arranged in the second section 112, and the second conveying member 300 and the first conveying member 200 jointly support and convey the workpiece 3000 to be conveyed; the control mechanism 400 is used to detect whether the workpiece 3000 to be conveyed enters or leaves the right-angle turning area 11, and according to the detection signal, control the rotation speed and rotation direction of the first conveying member 200 and the second conveying member 300.

[0054] When the workpiece 3000 to be conveyed enters the right-angle turning area 11, the first conveying member 200 rotates at a first preset speed and decelerates together with the second conveying member 300 to convey the workpiece 3000 to be conveyed to the positioning area; when the workpiece 3000 to be conveyed leaves the right-angle turning area 11, the first conveying member 200 rotates at a second preset speed and accelerates together with the second conveying member 300 to output the workpiece 3000 to be conveyed from the right-angle turning area 11, wherein the first preset speed is less than the second preset speed.

[0055] The bracket 100 is used to install components such as the first conveyor 200, the second conveyor 300, and the control mechanism 400. The conveying channel 10 on the bracket 100 is used to connect two workstations to convey the workpiece to be conveyed 3000 between different workstations. The structures of the first conveyor 200 and the second conveyor 300 are similar, and both are used to convey the workpiece to be conveyed 3000. The first conveyor 200 and the second conveyor 300 can but are not limited to using belt transmission and other parts. The number of control mechanisms 400 can be multiple. For example, one control mechanism 400 controls the first conveyor 200, and another control mechanism 400 controls the second conveyor 300.

[0056] The working principle of the conveying device 1000 will be described below in combination with the specific process of the conveying electrode assembly.

[0057] Suppose it is necessary to convey the electrode assembly from the first workstation to the second workstation. The electrode assembly will pass through the right-angle turning area 11 of the conveying channel 10 during the conveying process. When passing through the right-angle turning area 11, it will successively pass through the first section 111 and the second section 112. When the electrode assembly moves towards the first section 111 in the conveying channel 10 and has not reached the right-angle turning area 11, the electrode assembly is conveyed at a speed a.

[0058] When the electrode assembly starts to enter the right-angle turning area 11, that is, the electrode assembly enters the first section 111 and starts to be conveyed by the first conveyor 200. At this time, the control mechanism 400 controls the first conveyor 200 to run at a speed b (the first preset speed), where b is less than a, so as to continue conveying the electrode assembly at a reduced speed. While the first conveyor 200 is running, the second conveyor 300 starts to run. The control mechanism 400 controls the second conveyor 300 to rotate to slow down the movement speed of the electrode assembly and adjust the posture of the electrode assembly so that the electrode assembly enters the positioning area in this posture.

[0059] When the electrode assembly is ready to leave the right-angle turning area 11, the control mechanism 400 controls the first conveyor 200 and the second conveyor 300 to run. The first conveyor 200 in the first section 111 runs at a speed c (the second preset speed). At this time, the second conveyor 300 in the second section 112 accelerates, and the first conveyor 200 and the second conveyor 300 jointly accelerate to continue conveying the electrode assembly forward, so as to convey the electrode assembly out of the right-angle turning area 11.

[0060] It should be noted that during the process of the electrode assembly exiting the right-angle turning area 11, the speed c of the first conveyor 200 is greater than the speed b of the first conveyor 200 when the electrode assembly enters the right-angle turning area 11. This is because when the electrode assembly enters the right-angle turning area 11, in order to prevent the electrode assembly from colliding with the bracket 100 due to excessive speed, it is necessary to slow down the speed of the electrode assembly entering the right-angle turning area 11. And the first conveyor 200 is used in cooperation with the second conveyor 300 to adjust the posture of the electrode assembly so that it can be output in a specific posture.

[0061] Subsequently, the first conveyor 200 and the second conveyor 300 run at an accelerated speed, thereby outputting the electrode assembly with adjusted posture from the right-angle turning area 11.

[0062] In summary, the control mechanism 400 controls the running speeds of the first conveyor 200 and the second conveyor 300 to slow down the speed of the electrode assembly to be conveyed that has just entered the right-angle turning area 11 and slowly convey it to the positioning area. Subsequently, the first conveyor 200 and the second conveyor 300 are used to accelerate and output it from the right-angle turning area 11. In this way, the electrode assembly to be conveyed can smoothly pass through the right-angle turning area 11, reducing the probability that the electrode assembly to be conveyed collides with the bracket 100 due to excessive speed when passing through the right-angle turning area 11 and causing damage to the electrode assembly to be conveyed, and protecting the electrode assembly while conveying the electrode assembly.

[0063] As Figure 1 and Figure 2 shown, in some embodiments, the control mechanism 400 includes a first detector 410, a second detector 420 and a driving member. The first detector 410 is disposed in the first section 111 and is used to detect whether the member to be conveyed 3000 enters the first section 111. The second detector 420 is disposed in the second section 112 and is used to detect whether the member to be conveyed 3000 enters the second section 112.

[0064] Both the first detector 410 and the second detector 420 are electrically connected to the driving member and send signals to the driving member. The driving member controls the rotation speed and rotation direction of the first conveyor 200 and the second conveyor 300 according to the received signals.

[0065] The structure of the first detector 410 is similar to that of the second detector 420. Both the first detector 410 and the second detector 420 include sensors, and the sensors are used to detect the member to be conveyed 3000. The driving member can be, but is not limited to, a motor, a cylinder, etc.

[0066] Exemplarily, when the item to be conveyed 3000 enters the first section 111, the first detector 410 can detect the item to be conveyed 3000 and send the relevant signal to the driving member. The driving member controls the first conveyor 200 to run at a first preset speed according to the received signal, and controls the second conveyor 300 to run, so as to slowly convey the item to be conveyed 3000 to the positioning area.

[0067] After the item to be conveyed 3000 is conveyed to the positioning area, some of the items to be conveyed 3000 can enter the second section 112 and be detected by the second detector 420. When the second detector 420 detects the item to be conveyed 3000, it can send a signal to the driving member. The driving member controls the first conveyor 200 and the second conveyor 300 to run according to the received signal, so as to accelerate the conveyance of the item to be conveyed 3000, thereby outputting the item to be conveyed 3000 from the right-angle turning area 11.

[0068] In this way, by setting the first detector 410 and the second detector 420 to detect in real time whether the item to be conveyed 3000 enters the first section 111 and the second section 112, and sending the detected signal to the driving member at any time, so as to control the rotation speed and rotation direction of the first conveyor 200 and the second conveyor 300 in real time through the driving member, and convey the item to be conveyed 3000 at a preset speed, the conveyance efficiency and conveyance stability of the item to be conveyed 3000 are improved.

[0069] In some embodiments, the number of the first conveyors 200 is multiple. All the first conveyors 200 are spaced apart along the first direction X and are linked, and one of the first conveyors 200 is connected to the driving member;

[0070] When the item to be conveyed 3000 enters the right-angle turning area 11, all the first conveyors 200 rotate forward around the second direction Y; when the item to be conveyed 3000 leaves the right-angle turning area 11, the first conveyor 200 rotates reversely around the second direction Y, and the second direction Y intersects the first direction X.

[0071] Exemplarily, the conveying component connected to the first section 111 conveys the item to be conveyed 3000 towards the first section 111 along the first direction X. The first conveyor 200 is configured as a roller. All the rollers are spaced apart along the first direction X. One of the rollers is used as a driving wheel and is connected to the driving member. Adjacent two rollers can be connected by a conveyor belt to realize the linkage between the rollers.

[0072] When the item to be conveyed 3000 enters the right-angle turning area 11, it is assumed that the driving member drives a first conveying member 200 to rotate clockwise (forward rotation) around the second direction Y, and the remaining first conveying members 200 rotate clockwise around the second direction Y under the drive of the above-mentioned first conveying member 200 to slowly convey the item to be conveyed 3000 forward. When the item to be conveyed 3000 is about to leave the right-angle turning area 11, the driving member drives a first conveying member 200 to rotate counterclockwise (reverse rotation) around the second direction Y, and the remaining first conveying members 200 rotate counterclockwise around the second direction Y under the drive of the above-mentioned first conveying member 200 to accelerate the output of the item to be conveyed 3000 from the right-angle turning area 11.

[0073] In this way, the first conveying members 200 are set to be linked, and there is no need to set multiple driving members to separately drive different first conveying members 200 to operate, reducing the number of driving members to be set, simplifying the structure of the conveying device 1000, and reducing the production cost of the conveying device 1000. In addition, setting the first conveying members 200 to be linked is beneficial to controlling the running speed between all the first conveying members 200.

[0074] In some embodiments, when the item to be conveyed 3000 enters the right-angle turning area 11, the second conveying member 300 rotates in reverse around the first direction X at a third preset speed; when the item to be conveyed 3000 leaves the right-angle turning area 11, the second conveying member 300 rotates forward around the first direction X at a fourth preset speed, where the third preset speed is less than the fourth preset speed.

[0075] Exemplarily, when the item to be conveyed 3000 enters the first section 111, the first conveying member 200 rotates clockwise (forward rotation) around the second direction Y at a speed b, and the second conveying member 300 rotates counterclockwise (reverse rotation) around the first direction X at a speed d (the third preset speed). At this time, the first conveying member 200 and the second conveying member 300 can cooperate to slowly convey the item to be conveyed 3000 to the positioning area and adjust the posture of the item to be conveyed 3000 so that the item to be conveyed 3000 is in dynamic balance relative to the support 100, to avoid the item to be conveyed 3000 colliding with the support 100 due to too fast conveying speed, resulting in a change in the conveying posture and thus being prone to collide with the support 100.

[0076] When the item to be conveyed 3000 is about to leave the right-angle turning area 11, the first conveying member 200 rotates counterclockwise (reverse rotation) around the second direction Y at a speed c, and the second conveying member 300 rotates forward (forward rotation) around the first direction X at a speed e (the fourth preset speed). At this time, the first conveying member 200 and the second conveying member 300 can accelerate the output of the item to be conveyed 3000 with the adjusted posture from the right-angle turning area 11.

[0077] With such a setting, by adjusting the rotation direction and speed of the second conveyor 300 to cooperate with the first conveyor 200, the conveying posture of the workpiece to be conveyed 3000 can be jointly adjusted, so as to protect the workpiece to be conveyed 3000 and reduce the probability that the conveying posture of the workpiece to be conveyed 3000 changes due to too fast conveying speed and then collides with the bracket 100.

[0078] Further, in some embodiments, the number of the second conveyors 300 is multiple, and all the second conveyors 300 are spaced apart along the second direction Y and are linked. One of the second conveyors 300 is connected to the driving member.

[0079] Exemplarily, the second conveyor 300 is configured as a roller, and all the rollers are spaced apart along the second direction Y. Adjacent two rollers can be connected by a conveyor belt to realize the linkage between the rollers. One of the second conveyors 300 is connected to the driving member. It should be noted that a driving member can be respectively arranged for the first section 111 and the second section 112, and the first conveyor 200 and the second conveyor 300 are driven and connected by different driving members, so as to better control the rotation speed, rotation direction of the first conveyor 200 and the rotation speed and rotation direction of the second conveyor 300.

[0080] In this way, the second conveyors 300 are set in a linked manner, and there is no need to set multiple driving members to respectively drive different second conveyors 300 to operate, which reduces the number of driving members to be set, simplifies the structure of the conveying device 1000, and reduces the production cost of the conveying device 1000. Moreover, setting the second conveyors 300 in a linked manner is beneficial to controlling the running speed between all the second conveyors 300.

[0081] Specifically, in some embodiments, the conveying device 1000 further includes a plurality of transmission members 500. A transmission member 500 is shared between adjacent two first conveyors 200, and they are transmission-connected through the transmission member 500; a transmission member 500 is also shared between adjacent two second conveyors 300, and they are transmission-connected through the transmission member 500.

[0082] For example, the transmission member 500 can be prepared by using a wedge belt, so as to reduce the preparation difficulty of the transmission member 500 and facilitate the preparation of the transmission member 500.

[0083] As for using one transmission member 500 to link two adjacent first conveying members 200 and also using one transmission member 500 to link two adjacent second conveying members 300, during actual operation, if at least one of the first conveying members 200 or the second conveying members 300 is damaged, it is convenient for users to quickly identify and repair. Moreover, compared with using different linkage components to connect two adjacent first conveying members 200 and two adjacent second conveying members 300, by adopting a single transmission member 500, only one type of mold needs to be produced to prepare the transmission member 500, reducing the production quantity of molds.

[0084] More specifically, the connection between the transmission member 500 and the first conveying member 200 is detachable, and the connection between the transmission member 500 and the second conveying member 300 is also detachable.

[0085] The connection method between the transmission member 500 and the first conveying member 200 can be but is not limited to sleeving and clamping. The connection method between the transmission member 500 and the second conveying member 300 is the same as that between the transmission member 500 and the first conveying member 200, and will not be elaborated here.

[0086] When any one of the transmission member 500, the first conveying member 200, and the second conveying member 300 is damaged, only the damaged component needs to be replaced, which reduces the maintenance cost compared with replacing the whole.

[0087] In some embodiments, the driving member includes a first sub-member and a second sub-member, and the control mechanism 400 further includes a first control member 430 and a second control member 440. The first control member 430, the second control member 440, the first sub-member, and the second sub-member are all electrically connected to the first detector 410 and the second detector 420. The first control member 430 is disposed in the first section 111. The first control member 430 controls the first sub-member according to the signal sent by the first detector 410 to control the first conveying member 200. The second control member 440 also controls the second sub-member according to the signal sent by the first detector 410 to control the second conveying member 300.

[0088] The second control member 440 is disposed in the second section 112. The first control member 430 controls the first sub-member according to the signal sent by the first detector 410 to control the first conveying member 200. The second control member 440 controls the second sub-member according to the signal sent by the second detector 420 to control the second conveying member 300.

[0089] Exemplarily, the first sub-component is disposed on the first section 111 and is drivingly connected to one of the first conveying members 200. The first control member 430 is also disposed on the first section 111 and is electrically connected to the first sub-component. When the first detector 410 detects that the item to be conveyed 3000 enters the first section 111, the first detector 410 sends a signal to the first control member 430 and the second control member 440. The first control member 430 controls the first sub-component according to the received signal, and drives the first conveying member 200 to rotate forward at a reduced speed around the second direction Y through the first sub-component.

[0090] The second control member 440 controls the second sub-component according to the received signal, and drives the second conveying member 300 to rotate reversely at a reduced speed around the first direction X through the second sub-component. In this way, the first conveying member 200 and the second conveying member 300 can cooperate in time to slowly convey the item to be conveyed 3000 that enters the first section 111 to the positioning area, and at the same time adjust the posture of the item to be conveyed 3000.

[0091] When the item to be conveyed 3000 enters the second section 112 and is detected by the second detector 420, the second detector 420 sends a signal to the first control member 430 and the second control member 440. The first control member 430 controls the first sub-component according to the received signal, and drives the first conveying member 200 to rotate reversely at an increased speed around the second direction Y through the first sub-component. The second control member 440 controls the second sub-component according to the received signal, and drives the second conveying member 300 to rotate forward at an increased speed around the first direction X through the second sub-component.

[0092] In this way, the item to be conveyed 3000 after the posture is adjusted can be accelerated and output from the right-angle turning area 11.

[0093] The above settings improve the accuracy of the cooperation between the first conveying member 200 and the second conveying member 300, and can quickly output the item to be conveyed 3000 from the right-angle turning area 11.

[0094] Further, in some embodiments, the first control member 430 is provided with a first operation part for adjusting the rotation speed of the first sub-component, and the second control member 440 is provided with a second operation part for adjusting the rotation speed of the second sub-component.

[0095] The user adjusts the rotation speed of the first sub-component by manipulating the first operation part, thereby adjusting the rotation speed of the first conveying member 200. And adjusts the rotation speed of the second sub-component by manipulating the second operation part, thereby adjusting the rotation speed of the second conveying member 300. With such a setting, it is convenient for the user to operate.

[0096] Such as Figure 4As shown, in some embodiments, the bracket 100 is divided into a first layer and a second layer in the vertical direction. A conveying channel 10 is provided in both the first layer and the second layer. The conveying direction of the first layer is opposite to that of the second layer. One of the first layer and the second layer is used to convey the piece to be conveyed 3000 carried by the carrier 2000, and the other is used to output the carrier without the piece to be conveyed 3000.

[0097] To further protect the piece to be conveyed 3000, the piece to be conveyed 3000 is usually placed on a carrier 2000 (such as a tray) for conveying.

[0098] Exemplarily, the conveying direction of the conveying channel 10 in the first layer is opposite to that of the conveying channel 10 in the second layer. The first layer of the bracket 100 is used to convey the carrier 2000 on which the piece to be conveyed 3000 is placed to convey the piece to be conveyed 3000. The second layer of the bracket 100 is used to convey the carrier 2000 to recycle the carrier 2000.

[0099] When the carrier 2000 on which the piece to be conveyed 3000 is placed moves from the output end to the receiving end of the first layer, the user removes the piece to be conveyed 3000 from the carrier 2000, and then puts the empty carrier 2000 into the conveying channel 10 of the second layer, so as to send back the carrier 2000. Repeating this process, the piece to be conveyed 3000 is continuously conveyed and the carrier 2000 is recycled.

[0100] By arranging two layers on the bracket 100 in the vertical direction, on the basis of realizing semi-automatic recycling of the carrier 2000, the space used for recycling the carrier 2000 is reduced.

[0101] In some embodiments, an anti-collision part is convexly provided on the bracket 100, and the anti-collision part is arranged at the edge of the right-angle turning area 11.

[0102] The anti-collision part can be prepared from materials with buffering functions such as silica gel and rubber. When the piece to be conveyed 3000 passes through the right-angle turning area 11, if the piece to be conveyed 3000 has a tendency to move outside the bracket 100, the anti-collision part can block the piece to be conveyed 3000, limit the piece to be conveyed 3000 within the conveying channel 10, reduce the probability of it falling from the bracket 100, and protect the piece to be conveyed 3000.

[0103] Specifically, in some embodiments, both the first conveyor 200 and the second conveyor 300 are detachably installed on the bracket 100.

[0104] For example, the first conveyor 200 can be installed on the bracket 100 by means of snap connection or the like. The installation method of the second conveyor 300 is the same as that of the first conveyor 200 and will not be elaborated here.

[0105] When the first conveyor 200 and the second conveyor 300 are damaged, it is convenient to disassemble and assemble the damaged components so as to replace them with new components, reducing the maintenance cost.

[0106] In addition, some embodiments of the present application further provide a conveying system, which includes a carrier 2000 and the conveying device 1000 in the above embodiments. The carrier 2000 is used to carry the workpiece to be conveyed 3000 and convey it through the conveying device 1000.

[0107] Based on the same inventive concept, since the conveying system includes the conveying device 1000, the conveying device 1000 also includes all the beneficial effects of the conveying device 1000, which will not be elaborated here.

[0108] Specifically, in one embodiment, the conveying device 1000 includes a bracket 100, a first conveyor 200, a second conveyor 300 and a control mechanism 400. The bracket 100 is divided into a first layer and a second layer in the vertical direction. Both the first layer and the second layer are provided with a conveying channel 10. The conveying direction of the first layer is opposite to that of the second layer. The first layer is used to convey the workpiece to be conveyed 3000 supported by the carrier 2000, and the second layer is used to output the carrier without the workpiece to be conveyed 3000. The right-angle turning area 11 of each conveying channel 10 is divided into a first section 111 and a second section 112 along the diagonal; the first conveyor 200 is arranged in the first section 111; the second conveyor 300 is arranged in the second section 112. The second conveyor 300 and the first conveyor 200 jointly support and convey the workpiece to be conveyed 3000.

[0109] The control mechanism 400 is used to detect whether the workpiece to be conveyed 3000 enters or leaves the right-angle turning area 11, and control the rotation speed and rotation direction of the first conveyor 200 and the second conveyor 300 according to the detection signal.

[0110] When the workpiece to be conveyed 3000 enters the first section 111, the first conveyor 200 rotates clockwise (forward rotation) around the second direction Y at a speed b, and the second conveyor 300 rotates counterclockwise (reverse rotation) around the first direction X at a speed d (the third preset speed). At this time, the first conveyor 200 and the second conveyor 300 can cooperate with each other to slowly convey the workpiece to be conveyed 3000 to the positioning area, and adjust the posture of the workpiece to be conveyed 3000 so that the workpiece to be conveyed 3000 is in dynamic balance relative to the bracket 100, so as to prevent the workpiece to be conveyed 3000 from colliding with the bracket 100 due to too fast conveying speed, resulting in a change in the conveying posture and thus being prone to collide with the bracket 100.

[0111] When the item to be conveyed 3000 is about to leave the right-angle turning area 11, the first conveyor 200 rotates counterclockwise (in reverse) around the second direction Y at a speed c, and the second conveyor 300 rotates clockwise (forward) around the first direction X at a speed e (the fourth preset speed). At this time, the first conveyor 200 and the second conveyor 300 can accelerate to output the item to be conveyed 3000 with an adjusted attitude from the right-angle turning area 11.

[0112] When the carrier 2000 with the item to be conveyed 3000 moves from the output end to the receiving end of the first layer, the user removes the item to be conveyed 3000 from the carrier 2000, and then places the empty carrier 2000 into the conveying channel 10 of the second layer, so as to send back the carrier 2000. Repeating this process continuously conveys the item to be conveyed 3000 and recovers the carrier 2000.

[0113] In summary, by controlling the operating speeds of the first conveyor 200 and the second conveyor 300 through the control mechanism 400, the speed of the electrode assembly to be conveyed just entering the right-angle turning area 11 is slowed down, and it is slowly conveyed to the positioning area and the attitude of the item to be conveyed 3000 is adjusted. Subsequently, the first conveyor 200 and the second conveyor 300 are used to accelerate and output it from the right-angle turning area 11. In this way, the electrode assembly to be conveyed can smoothly pass through the right-angle turning area 11, reducing the probability that the electrode assembly to be conveyed collides with the bracket 100 due to too high a speed when passing through the right-angle turning area 11, resulting in damage to the electrode assembly to be conveyed, and protecting the electrode assembly while conveying it.

[0114] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0115] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
