[0009] In the above manner, the spacing adjustment assembly can be used to adjust the interval distance between the two conveyor belts, so that the clamps can adapt to items to be conveyed with different widths.

[0010] In some embodiments, the spacing adjustment assembly includes a first base, two first support frames, and a frame driving mechanism. The two first support frames are arranged on the first base, and the two first support frames are used to respectively support the corresponding one of the two conveyor belts. The frame driving mechanism can drive at least one of the two first support frames to move relative to the first base along the interval direction.

[0011] In the above manner, the frame driving mechanism can drive the first support frame, and further drive at least one of the two conveyor belts to move along the spacing direction to adjust the spacing between the two conveyor belts.

[0012] In some embodiments, the frame driving mechanism is configured to be able to synchronously drive the two first support frames to move in opposite directions along the spacing direction.

[0013] In the above manner, the frame driving mechanism can simultaneously drive the two first support frames to move away from or close to each other along the spacing direction, and further quickly adjust the spacing between the two conveyor belts.

[0014] In some embodiments, a slide rail extending along the spacing direction is provided on the first base, and the first support frame driven by the frame driving mechanism is slidably supported on the slide rail.

[0015] In the above manner, the resistance when the first support frame driven by the frame driving mechanism moves can be reduced.

[0018] In some embodiments, the number of the auxiliary support assemblies is at least two, and the at least two auxiliary support assemblies are arranged at intervals along the conveying direction of the two conveyor belts, and the spacing adjustment assembly is located between the two auxiliary support assemblies.

[0019] In the above manner, the pressure received by each auxiliary support assembly and the spacing adjustment assembly can be reduced, and further the spacing adjustment assembly can more easily drive the two conveyor belts to approach or separate from each other.

[0020] In some embodiments, the two clamps are configured to clamp the article to be conveyed along the conveying direction of the two conveyor belts.

[0023] In the above manner, the two transmission mechanisms can drive the two conveyor belts to move asynchronously, thereby adjusting the distance between the two jigs along the conveying direction.

[0024] In some embodiments, the driving assembly includes a transmission mechanism and a transfer mechanism, and one of the two conveyor belts is connected to the transmission mechanism through the transfer mechanism; the asynchronous mode includes that the transfer mechanism disconnects the connection between one of the two conveyor belts and the transmission mechanism in response to a control signal, so that one of the two conveyor belts remains stationary, and one of the two conveyor belts moves along the conveying direction under the drive of the transmission mechanism; or the asynchronous mode includes that the transfer mechanism switches in response to a control signal to make the two conveyor belts move in opposite directions along the conveying direction and / or at different speeds.

[0025] In the above manner, the two conveyor belts can be made to move in opposite directions and / or at different speeds by controlling the working state of the transfer mechanism. In addition, the two conveyor belts are both driven by the same driving assembly, which is conducive to the synchronous movement of the two conveyor belts when conveying the items to be conveyed.

[0026] In some embodiments, the driving assembly is further configured to be able to drive the two conveyor belts to convey the two jigs along the conveying direction in a synchronous manner, so that the distance between the two jigs along the conveying direction remains unchanged.

[0053] With the development of battery technology, batteries are applied in more and more fields and gradually replace traditional fossil energy in the field of automotive power. Batteries can store chemical energy and controllably convert chemical energy into electrical energy. In recyclable batteries, after discharging, the active substances can be activated by charging and continue to be used.

[0054] At present, there are more and more types of electronic devices that require batteries. For example, the electronic devices can be headphones, mobile phones, computers, bracelets, smart watches, smart glasses, cars, electric vehicles, etc. Moreover, the specifications of the batteries required by these electronic devices often vary. Additionally, even for the same type of electronic device (such as a car), the specifications of the batteries required may also be different. Therefore, manufacturers need to produce batteries of various specifications to meet different needs. Inevitably, conveying devices are needed in the process of producing batteries of different specifications. If matching conveying devices are purchased or made separately for different specifications of batteries, the manufacturing cost will be greatly increased.

[0055] In order to enable the conveying device to be used for transporting batteries of different specifications and reduce the manufacturing cost, it is necessary to design a replaceable conveying device. Optionally, the conveying device may include two conveyor belts, at least one fixture group, and an adjustment component. The two conveyor belts are arranged side by side and spaced apart from each other. Each fixture group includes two fixtures. The two fixtures are respectively disposed on one of the two conveyor belts. The two fixtures cooperate with each other to clamp the item to be conveyed. The adjustment component is configured to adjust the spacing distance between the two fixtures in response to a control signal.

[0056] Based on the above considerations, the present application provides a conveying device and a battery assembly system. In the above manner, the adjustment component can adjust the relative positions of the two fixtures according to the control signal, so that the fixtures can clamp items to be conveyed of different models, and further improve the adaptability of the conveying device to items to be conveyed of different models.

[0057] The battery disclosed in the embodiments of the present application can be used in power-consuming devices that use the battery as a power source or various energy storage systems that use the battery as an energy storage element. The power-consuming devices can be, but are not limited to, mobile phones, tablets, laptop computers, electric toys, electric tools, battery cars, electric vehicles, ships, spacecrafts, etc. Among them, the electric toys can include fixed or mobile electric toys, such as game consoles, electric vehicle toys, electric ship toys, and electric aircraft toys, etc. The spacecrafts can include airplanes, rockets, space shuttles, and spaceships, etc. The battery assembly system disclosed in the embodiments of the present application can be used to assemble the above-mentioned batteries. The conveying device disclosed in the embodiments of the present application can be used to convey batteries or semi-finished products of batteries in the battery assembly system.

[0058] The following describes an exemplary structure of the conveying device involved in the embodiments of the present application. Additionally, it should be noted that the conveying device involved in the following embodiments of the present application can be used to convey finished batteries or semi-finished batteries, and can also be used to convey other types of items to be conveyed in other fields, such as mobile phones, tablets, smart speakers, displays, etc.

[0059] See Figure 1 and Figure 2, according to one or more embodiments of the present application, optionally, the conveying device 10 includes two conveyor belts 100, at least one fixture group 120 and an adjustment assembly 140. The two conveyor belts 100 are arranged side by side and spaced apart from each other. Each fixture group 120 includes two fixtures 121, and the two fixtures 121 are respectively arranged on one of the two conveyor belts 100. The two fixtures 121 cooperate with each other to clamp the item to be conveyed. The adjustment assembly 140 can adjust the spacing distance between the two fixtures 121.

[0060] The fixture group 120 may include at least two fixtures 121, and the spacing distance between the two fixtures 121 is adjustable to adapt to items to be conveyed with different specifications. Among them, the spacing distance may include the spacing distance L1 along the spacing direction of the two conveyor belts 100 and the spacing distance L2 along the conveying direction of the conveyor belt 100. When the spacing distance L1 along the spacing direction of the two conveyor belts 100 and the spacing distance L2 along the conveying direction of the conveyor belt 100 between the two fixtures 121 match two of the length, width and height of the item to be conveyed, the item to be conveyed can be firmly clamped. Subsequently, by controlling the synchronous movement of the two conveyor belts 100, the item to be conveyed can be conveyed.

[0061] The fixture 121 may include a first limiting side 121a and a second limiting side 121b. The first limiting side 121a may be parallel to the conveying direction of the conveyor belt 100. The second limiting side 121b may be parallel to the spacing direction of the two conveyor belts 100. The spacing distance L1 between the two fixtures along the spacing direction of the two conveyor belts 100 may refer to the distance between the first limiting sides 121a of the two fixtures 121. The spacing distance L2 between the two fixtures along the conveying direction of the conveyor belt 100 may refer to the distance between the second limiting sides 121b of the two fixtures.

[0062] Optionally, the fixture group 120 may further include two auxiliary fixtures 122. The two auxiliary fixtures 122 may be respectively arranged on the two conveyor belts 100. In addition, the auxiliary fixture 122 and the fixture 121 arranged on the same conveyor belt 100 may be spaced apart. The auxiliary fixture 122 may have a supporting bottom surface 122a for supporting the item to be conveyed.

[0063] See Figure 3 , the principle of the adjustment assembly 140 adjusting the spacing distance L1 between the two fixtures 121 along the spacing direction of the two conveyor belts 100 may be: driving the two conveyor belts 100 to move relatively closer or relatively farther apart, further driving the fixtures 121 arranged on the conveyor belts 100 to move relatively closer or relatively farther apart, or may be: directly driving the two fixtures 121 to move relatively closer or relatively farther apart along the spacing direction of the conveyor belts 100 relative to the conveyor belts 100.

[0064] See Figure 4, the principle of the adjusting component 140 for adjusting the spacing distance L2 between the two clamps 121 along the conveying direction of the conveyor belt 100 can be: driving the two conveyor belts 100 to rotate out of sync, so as to cause the clamps 121 provided on the conveyor belt 100 to move relatively, or it can be: directly driving the two clamps 121 to move relatively along the conveying direction of the conveyor belt 100.

[0065] As shown in the figure, the spacing distance L2 between the two clamps 121 along the conveying direction of the conveyor belt 100 is greater than 0 and less than the distance from the first limiting side 121a to the adjacent clamp group 120. Considering the stability of the item to be conveyed, the item to be conveyed can be placed on the clamp 121 and the auxiliary clamp 122. That is, preferably, the spacing distance can be greater than the spacing distance L4 between the clamp 121 and the auxiliary clamp 122 in the clamp group 120 and less than the spacing L3 between two adjacent clamp groups 120.

[0066] In the above manner, the adjusting component 140 can adjust the relative positions of the two clamps 121 so that the clamps 121 can clamp items to be conveyed of different models, and further improve the adaptability of the conveying device 10 to items to be conveyed of different models.

[0067] According to one or more embodiments of the present application, optionally, the two clamps 121 are arranged to clamp the item to be conveyed along the spacing direction of the two conveyor belts 100.

[0068] The adjusting component 140 may include a spacing adjusting component 141. The spacing adjusting component 141 can adjust the spacing distance between the two conveyor belts 100 along the spacing direction, and thereby adjust the spacing distance L1 between the two clamps 121 along the spacing direction.

[0069] In the above manner, the spacing adjusting component 141 can be used to adjust the spacing distance between the two conveyor belts 100, so that the clamps 121 can adapt to items to be conveyed with different widths. In addition, when the spacing adjusting component 141 can adjust the spacing distance between the two conveyor belts 100, and thereby simultaneously adjust the spacing distance L1 of the clamps 121 in multiple clamp groups 120 provided on the conveyor belt 100 along the spacing direction, the spacing distance adjustment of multiple clamp groups 120 can be quickly completed.

[0070] See Figure 5 , according to one or more embodiments of the present application, optionally, the spacing adjusting component 141 includes a first base 1410, two first support frames 1412, and a frame driving mechanism 1414. The two first support frames 1412 are arranged on the first base 1410. The two first support frames 1412 are used to respectively support the corresponding one of the two conveyor belts 100. The frame driving mechanism 1414 can drive at least one of the two first support frames 1412 to move relative to the first base 1410 along the spacing direction.

[0071] The frame driving mechanism 1414 may include a driving motor and a lead screw nut mechanism. The driving motor may have an output shaft to output a rotational motion. The lead screw nut mechanism may include a lead screw and a nut. The extending direction of the lead screw may be parallel to the spacing direction of the two conveyor belts 100. The nut is disposed on the lead screw, and the lead screw is connected to the output shaft. When the output shaft rotates, it can drive the lead screw to rotate and drive the nut to move linearly along the direction of the lead screw. A support frame 1412 may be connected to the nut to move along the spacing direction of the two conveyor belts under the action of the nut.

[0072] In the above manner, the frame driving mechanism 1414 can drive the first support frame 1412, and further drive at least one of the two conveyor belts 100 to move along the spacing direction to adjust the spacing between the two conveyor belts 100. When the spacing adjustment assembly 141 can drive at least one first support frame 1412 to move along the spacing direction through the frame driving mechanism 1414, it can further enable the two conveyor belts 100 to approach or move away from each other.

[0073] According to one or more embodiments of the present application, optionally, the frame driving mechanism 1414 is arranged to be able to synchronously drive the two first support frames 1412 to move in opposite directions along the spacing direction.

[0074] In the above manner, the frame driving mechanism 1414 can simultaneously drive the two first support frames 1412 to move away from or close to each other along the spacing direction, and thus quickly adjust the spacing between the two conveyor belts 100.

[0075] According to one or more embodiments of the present application, optionally, a slide rail 1416 extending along the spacing direction is provided on the first base 1410, and the first support frame 1412 driven by the frame driving mechanism 1414 is slidably supported on the slide rail 1416.

[0076] When the frame driving mechanism 1414 can drive the first support frame 1412 to slide along the slide rail 1416 and drive the conveyor belt 100 to move. In the above manner, the resistance when the first support frame 1412 driven by the frame driving mechanism 1414 moves can be reduced.

[0077] According to one or more embodiments of the present application, optionally, the conveying device 10 includes an auxiliary support assembly 150. The auxiliary support assembly 150 includes a second base 1500 and two second support frames 1502. The two second support frames 1502 are disposed on the second base 1500. The two second support frames 1502 are used to support the corresponding one of the two conveyor belts 100 respectively. The second support frame 1502 is arranged to be movable relative to the second base 1500 under the drive of the first support frame 1412 driven by the frame drive mechanism 1414.

[0078] Sliding rails extending in the spacing direction may be provided on the second base 1500. When the frame drive mechanism 1414 drives the two conveyor belts 100 to move relative to each other through the first support frame 1412, since the second support frame 1502 is also provided with the conveyor belt 100, the second support frame 1502 can move synchronously relative to the second base 1500 under the drive of the conveyor belt 100.

[0079] In the above manner, by providing the auxiliary support assembly 150, the two conveyor belts 100 can be kept substantially parallel during the process of approaching or separating from each other.

[0080] According to one or more embodiments of the present application, optionally, the number of the auxiliary support assemblies 150 is at least two, and the at least two auxiliary support assemblies 150 are arranged at intervals along the conveying direction of the two conveyor belts 100, and the spacing adjustment assembly 141 is located between the two auxiliary support assemblies 150.

[0081] In the above manner, the pressure on each of the auxiliary support assemblies 150 and the spacing adjustment assembly 141 can be reduced, so that the spacing adjustment assembly 141 can more easily drive the two conveyor belts 100 to approach or separate from each other.

[0082] According to one or more embodiments of the present application, optionally, the two clamps 121 are arranged to clamp the item to be conveyed along the conveying direction of the two conveyor belts 100.

[0083] The adjustment assembly 140 includes a drive assembly 145. The drive assembly 145 can drive the two conveyor belts 100 to convey the two clamps 121 along the conveying direction in an asynchronous manner, so as to adjust the spacing distance L2 between the two clamps 121 along the conveying direction.

[0084] Among them, the drive assembly 145 driving the two conveyor belts 100 in an asynchronous manner may mean that the drive assembly 145 drives the two conveyor belts 100 to move in a non-synchronous manner. For example, the drive assembly 145 can drive the two conveyor belts 100 to run in opposite directions, or the drive assembly 145 can drive the two conveyor belts 100 to move at different speeds.

[0085] In this way, the driving assembly 145 can control the two conveyor belts 100 to move asynchronously, thereby adjusting the spacing L2 of the two clamps 121 along the conveying direction. In addition, by controlling the two conveyor belts 100 to move asynchronously, multiple clamp groups 120 of the conveyor belt 100 can also be adjusted simultaneously.

[0086] According to one or more embodiments of the present application, optionally, the driving assembly 145 includes two transmission mechanisms 147. The two transmission mechanisms 147 respectively drive the two conveyor belts 100 to move along the conveying direction.

[0087] Optionally, the asynchronous method includes sending a control signal to one of the two transmission mechanisms 147 so that the conveyor belt 100 corresponding to one of the two transmission mechanisms 147 moves along the conveying direction, and the conveyor belt 100 corresponding to the other of the two transmission mechanisms 147 remains stationary.

[0088] The control signal may be a control signal sent by a processor or a host computer, and may specifically be a control signal output by the processor or the host computer according to the identification information and matching the identification information. The identification information may be used to characterize the size information (e.g., length, width, or height) or model information of the object to be transported, which may be input by a user through the human-machine interface 180, or may be recognized by an image processing component.

[0089] Optionally, the control signal may also include a first control signal and a second control signal. The asynchronous mode includes sending the first control signal to one of the two transmission mechanisms 147 and sending the second control signal to the other of the two transmission mechanisms 147, so that the two conveyor belts 100 move in opposite directions along the conveying direction and / or move at different speeds.

[0090] In the above manner, the two transmission mechanisms 147 can drive the two conveyor belts 100 to move asynchronously, thereby adjusting the spacing distance L2 between the two clamps 121 along the conveying direction.

[0091] According to one or more embodiments of the present application, optionally, the driving assembly 145 includes a transmission mechanism 147 and a switching mechanism. One of the two conveyor belts 100 is connected to the transmission mechanism 147 via the switching mechanism.

[0092] Optionally, the asynchronous method includes a switching mechanism disconnecting the connection between one of the two conveyor belts 100 and the transmission mechanism 147 in response to a control signal, so that one of the two conveyor belts 100 remains stationary, and one of the two conveyor belts 100 moves along the conveying direction under the drive of the transmission mechanism 147.

[0093] The transfer mechanism can specifically be a clutch. When the transfer mechanism does not receive a control signal, the drive mechanism 147 can directly control the movement of one of the two conveyor belts 100 and control the other to move synchronously through the transfer mechanism. When the transfer mechanism receives the control signal, the transfer mechanism disconnects the power connection between the other of the two conveyor belts 100 and the drive mechanism 147, so that the conveyor belt 100 directly driven by the drive mechanism 147 moves, and the conveyor belt 100 indirectly driven by the drive mechanism 147 through the transfer mechanism remains stationary.

[0094] Optionally, the asynchronous mode includes that the transfer mechanism responds to the control signal and switches to make the two conveyor belts 100 move in opposite directions along the conveying direction and / or move at different speeds.

[0095] The transfer mechanism can specifically be a transmission. When the transfer mechanism does not receive a control signal, the drive mechanism 147 can directly control the movement of one of the two conveyor belts 100 and control the other to move synchronously through the transfer mechanism. When the transfer mechanism receives the control signal, the transfer mechanism operates in a speed-changing mode, so that the conveyor belt 100 directly driven by the drive mechanism 147 and the conveyor belt 100 indirectly driven by the drive mechanism 147 through the transfer mechanism can move in opposite directions and / or move at different speeds.

[0096] Through the above method, the two conveyor belts 100 can be made to move in opposite directions and / or move at different speeds by controlling the working state of the transfer mechanism. In addition, both of the two conveyor belts 100 are driven by the same drive assembly 145, which is conducive to the synchronous movement of the two conveyor belts 100 when conveying the items to be conveyed.

[0097] According to one or more embodiments of the present application, optionally, the drive assembly 145 is further arranged to be able to drive the two conveyor belts 100 to convey the two jigs 121 in the conveying direction in a synchronous manner, so that the interval distance L2 between the two jigs 121 in the conveying direction remains unchanged.

[0098] Through the above method, the drive assembly 145 can move synchronously for transporting the items to be conveyed. When a change of model (change of the type or specification of the items to be conveyed) is required, generally there is no previous item to be conveyed or the item to be conveyed about to be conveyed on the conveying device 10. At this time, the drive assembly 145 controls the conveyor belt 100 to move in an asynchronous manner, thereby realizing the change of model. After the change of model is completed, the conveying can be carried out in a synchronous manner.

[0099] According to one or more embodiments of the present application, optionally, the conveying device 10 further includes a control system 160. The control system 160 is configured to generate a control signal according to the target interval distance between the two jigs 121 corresponding to the item to be conveyed and the actual interval distance between the two jigs 121.

[0100] The actual spacing distance between the two jigs 121 may refer to the spacing distance between the two jigs 121 before changeover. The actual spacing distance may include the actual distance in the spacing direction of the two conveyor belts 100 and the actual distance in the conveying direction of the conveyor belt 100. The target spacing distance between the two jigs 121 may refer to the desired spacing distance between the two jigs 121 after changeover is completed. The target spacing distance may include the target distance in the spacing direction of the two conveyor belts 100 and the target distance in the conveying direction of the conveyor belt 100.

[0101] The principle of generating a control signal based on the target spacing distance between the two jigs 121 and the actual spacing distance between the two jigs 121 may be: obtaining the actual distance and the target distance of the two jigs 121 in the spacing direction of the two conveyor belts 100, and calculating a first difference between the actual distance and the target distance of the two jigs 121 in the spacing direction of the two conveyor belts 100; obtaining the actual distance and the target distance of the two jigs 121 in the conveying direction of the conveyor belt 100, and calculating a second difference between the actual distance and the target distance of the two jigs 121 in the conveying direction of the conveyor belt 100, and generating a control signal based on the first difference and the second difference.

[0102] After the adjustment assembly 140 responds to the control signal, it can control the spacing adjustment assembly 141 to drive the two conveyor belts 100 to move relatively in the spacing direction by a first distance. Wherein, the first distance is related to the first difference. The first distance may be equal to the first difference or slightly greater than the first difference.

[0103] After the adjustment assembly 140 responds to the control signal, it can control the drive assembly 145 to drive the two conveyor belts 100 to move relatively in the conveying direction in an asynchronous manner by a second distance. Wherein, the second distance may be related to the second difference. The second distance may be equal to the second difference or slightly greater than the second difference.

[0104] In the above manner, the conveying device 10 can be used to convey articles to be conveyed of different specifications.

[0105] See Figure 6 , according to one or more embodiments of the present application, optionally, the conveying device 10 further includes a human-machine interface 180, and the human-machine interface 180 is configured to allow a user to input or specify identification information of the article to be conveyed, and the control system 160 retrieves the target spacing distance from a preset database according to the identification information of the article to be conveyed.

[0106] Wherein, the identification signal may be the model of the article to be conveyed. The target spacing distance in the preset database may be related to the specification dimensions of the article to be conveyed of this model. The specification dimensions may include at least one of length, width and height.

[0107] The human-machine interface may refer to the interface of an input-output device through which a person establishes contact with the device to exchange information. The input-output device may include at least one of a keyboard, a display, a mouse, and a touch screen.

[0108] In the above manner, the user can conveniently input identification information (such as the model of the object to be conveyed) through the human-machine interface 180, and the control system 160 can determine the target interval distance that matches the conveyed object based on the identification information.

[0109] According to one or more embodiments of the present application, a battery assembly system may include a conveying device and an assembly device, wherein the conveying device is used to convey the structure to be assembled to each workstation of the assembly device, and the conveying section of the conveying device that conveys the assembly structure to any workstation includes the above-mentioned conveying device.

The housing insertion device is a pushing mechanism or a clamping mechanism, which can stably move the electrode assembly towards the open end of the housing and enter the accommodation cavity through the open end. Similarly, the tab threading device can adopt a clamping structure or a guiding structure, which can guide the tab portion to smoothly pass through the through hole without interfering with the housing.

The purpose of the bottom cover welding device is to weld the circumferential edge of the bottom cover and the open end of the housing, and it is also a laser welding device.

[0115] In addition, the assembly equipment is not limited to including the tab welding device, the housing insertion device, the tab threading device, the terminal welding device, and the bottom cover welding device. Exemplarily, when the number of electrode assemblies is multiple, for example, two, the assembly equipment further includes a pairing device, which is used to stack multiple electrode assemblies so that the tab pieces of the two electrode assemblies are substantially opposite to each other, so that the conveying structure can convey the paired electrode assemblies to the tab welding device for welding the tab pieces to facilitate the formation of the tab portion. Another example is that in order to ensure the reliability of the battery assembly process, a dust removal and NG detection station can also be added between any two adjacent stations, which is not limited in this embodiment.

The frame drive mechanism 1414 is configured to drive at least one of the two first support frames 1412 to move relative to the first base 1410 in the spacing direction in response to a control signal.
