[0001] This application claims priority to Chinese patent application No. 2023116414364, filed on November 30, 2023, entitled “Conveying Equipment and Battery Assembly System,” which is incorporated herein by reference in its entirety.

Technical field

[0002] The present application relates to the technical field of mechanical equipment, in particular to conveying equipment and battery assembly systems. [Background Technology]

[0003] Conveying equipment is a common device used to transport items in life and engineering projects, and is often called a conveyor or conveying equipment.

[0004] However, current conveying equipment can usually only be used to transport items of a certain specification. Therefore, when transporting items of different specifications, multiple items of different specifications are often required, which greatly increases the cost.

[0005] In addition, the above statements are only used to provide background technical information related to the present application and do not necessarily constitute prior art.

[0006] [Summary of the invention]

[0007] In view of the above problems, the present application provides a conveying device and a battery assembly system, which can improve the adaptability of the conveying device to batteries of different models.

[0008] In a first aspect, an embodiment of the present application provides a conveying device, which includes two conveyor belts, at least two clamps and an adjustment assembly; the two conveyor belts are arranged side by side and at intervals; two clamps are respectively arranged on the two conveyor belts, and the two clamps cooperate with each other to clamp the items to be conveyed; the adjustment assembly can adjust the interval distance between the two clamps.

[0009] In the above manner, the adjustment component can adjust the relative positions of the two clamps so that the clamps can clamp objects of different sizes to be conveyed, and further improve the adaptability of the conveying device to objects of different sizes to be conveyed.

[0010] In some embodiments, the two clamps are configured to clamp the items to be conveyed along the spacing direction of the two conveyor belts, and the adjustment component includes a spacing adjustment component, which can adjust the spacing distance between the two conveyor belts along the spacing direction, and then adjust the spacing distance between the two clamps along the spacing direction.

[0011] In the above manner, the spacing adjustment assembly can be used to adjust the spacing distance between the two conveyor belts, thereby enabling the clamp to adapt to objects to be conveyed with different widths.

[0012] 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. The two first support frames are used to support the corresponding one of the two conveyor belts respectively. The frame driving mechanism can drive at least one of the two first support frames to move relative to the first base along the spacing direction.

[0013] In the above manner, the frame driving mechanism can drive the first supporting frame, thereby driving at least one of the two conveyor belts to move along the spacing direction to adjust the distance between the two conveyor belts.

[0014] In some embodiments, the frame driving mechanism is configured to synchronously drive the two first support frames to move in opposite directions along the spacing direction.

[0015] In the above manner, the frame driving mechanism can simultaneously drive the two first support frames to move away from or toward each other along the spacing direction, thereby quickly adjusting the spacing between the two conveyor belts.

[0016] 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.

[0017] By adopting the above-mentioned method, the resistance when the first supporting frame is driven by the frame driving mechanism to move can be reduced.

[0018] In some embodiments, the conveying equipment includes an auxiliary support assembly, which includes a second base and two second support frames. The two second support frames are arranged on the second base. The two second support frames are used to support the corresponding one of the two conveyor belts respectively. The second support frame is configured to be able to move relative to the second base under the drive of the first support frame driven by the frame driving mechanism.

[0019] In the above manner, by providing the auxiliary support assembly, the two conveyor belts can be kept roughly parallel when approaching or moving away from each other.

[0020] In some embodiments, the number of the auxiliary support assemblies is at least two, and the at least two auxiliary support assemblies are spaced apart along the conveying direction of the two conveyor belts, and the spacing adjustment assembly is located between the two auxiliary support assemblies.

[0021] By adopting the above-mentioned method, the pressure on each auxiliary support assembly and the spacing adjustment assembly can be reduced, thereby making it easier for the spacing adjustment assembly to drive the two conveyor belts closer to or farther away from each other.

[0022] In some embodiments, the two clamps are configured to clamp the items to be conveyed along the conveying direction of the two conveyor belts, and the adjustment component includes a drive component, which can drive the two conveyor belts in an asynchronous manner to convey the two clamps along the conveying direction, thereby adjusting the spacing distance between the two clamps along the conveying direction.

[0023] In the above manner, the driving assembly can control the two conveyor belts to move asynchronously, thereby adjusting the spacing between the two clamps along the conveying direction.

[0024] In some embodiments, the drive assembly includes two transmission mechanisms, which respectively drive two conveyor belts to move along the conveying direction; the asynchronous method includes sending a control signal to one of the two transmission mechanisms so that the conveyor belt corresponding to one of the two transmission mechanisms moves along the conveying direction, and the conveyor belt corresponding to the other of the two transmission mechanisms remains stationary, or the control signal includes a first control signal and a second control signal, and the asynchronous method includes sending the first control signal to one of the two transmission mechanisms and sending the first control signal to the other of the two transmission mechanisms so that the two conveyor belts move in opposite directions along the conveying direction and / or move at different speeds.

[0025] In the above manner, the two transmission mechanisms can drive the two conveyor belts to move asynchronously, thereby adjusting the spacing between the two clamps along the conveying direction.

[0026] In some embodiments, the drive assembly includes a transmission mechanism and a transfer mechanism, and one of the two conveyor belts is connected to the transmission mechanism via the transfer mechanism; the asynchronous mode includes the transfer mechanism disconnecting 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 the transfer mechanism switching in response to a control signal so that the two conveyor belts move in opposite directions along the conveying direction and / or move at different speeds.

[0027] In this way, the two conveyor belts can be moved in opposite directions and / or at different speeds by controlling the working state of the switching mechanism. In addition, the two conveyor belts are driven by the same drive assembly, thereby helping the two conveyor belts to move synchronously when transmitting the item to be transmitted.

[0028] In some embodiments, the driving assembly is further configured to drive the two conveyor belts in a synchronous manner to convey the two clamps along the conveying direction, so that the spacing distance between the two clamps along the conveying direction remains unchanged.

[0029] In this way, the drive components can move synchronously to transport the items to be conveyed.

[0030] In some embodiments, the conveying device further comprises a control system configured to generate a control signal according to a target spacing distance between two clamps corresponding to the objects to be conveyed and an actual spacing distance between the two clamps.

[0031] In the above manner, the conveying device can be used to convey objects of different specifications.

[0032] In some embodiments, the conveying device further comprises a human-machine interface configured to allow a user to input or specify identification information of the item to be conveyed, and the control system retrieves the target interval distance from a preset database according to the identification information of the item to be conveyed.

[0033] In the above manner, the user can conveniently input identification information (such as the model of the item to be conveyed) through the human-machine interface, and the control system can determine the target spacing distance that matches the conveyed item based on the identification information.

[0055] With the advancement of battery technology, batteries are being used in a growing number of fields and are gradually replacing traditional fossil fuels in the automotive powertrain sector. Batteries store chemical energy and controllably convert it into electrical energy. In recyclable batteries, after discharge, the active materials can be activated by recharging for continued use.

[0056] Currently, there are more and more types of electronic devices that require batteries. For example, electronic devices can be headphones, mobile phones, computers, bracelets, smart watches, smart glasses, cars, electric cars, etc. The specifications of the batteries required for these electronic devices are often different. In addition, even the same type of electronic device (such as a car) may require different battery specifications. Therefore, manufacturers need to produce batteries of various specifications to meet different needs. In the process of producing batteries of different specifications, conveying equipment is inevitably required. If matching conveying equipment is purchased or made for batteries of different specifications, the manufacturing cost will be greatly increased.

[0057] In order to enable the conveying equipment to be used to transport batteries of different specifications and reduce manufacturing costs, it is necessary to design a replaceable conveying equipment. Optionally, the conveying equipment may include two conveyor belts, at least one clamp group, and an adjustment component. The two conveyor belts are arranged side by side and spaced apart. Each clamp group includes two clamps. The two clamps are respectively arranged on a corresponding one of the two conveyor belts. The two clamps cooperate with each other to clamp the items to be conveyed. The adjustment component is configured to adjust the spacing between the two clamps in response to a control signal.

[0058] Based on the above considerations, the present application provides a conveying device and a battery assembly system. Through the above method, the adjustment component can adjust the relative position of the two clamps according to the control signal, so that the clamps can clamp different types of objects to be conveyed, further improving the adaptability of the conveying device to different types of objects to be conveyed.

[0059] The battery disclosed in the embodiment of the present application can be used in an electrical device that uses a battery as a power source or various energy storage systems that use a battery as an energy storage element. The electrical device can be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, and the like. Among them, electric toys can include fixed or mobile electric toys, for example, game consoles, electric car toys, electric ship toys, and electric airplane toys, and the like, and spacecraft can include airplanes, rockets, space shuttles, and spacecraft, and the like. The battery assembly system disclosed in the embodiment of the present application can be used to assemble the above-mentioned batteries. The conveying equipment disclosed in the embodiment of the present application can be used to convey batteries or semi-finished batteries in a battery assembly system.

[0060] The following describes an exemplary structure of the conveying equipment involved in the embodiments of the present application. In addition, it should be noted that the conveying equipment 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 in other fields to convey other types of items to be conveyed, such as mobile phones, tablets, smart speakers, monitors, etc.

[0061] Referring to Figures 1 and 2 , according to one or more embodiments of the present application, a conveyor apparatus 10 optionally includes two conveyor belts 100, at least one clamp assembly 120, and an adjustment assembly 140. The two conveyor belts 100 are arranged side by side and spaced apart. Each clamp assembly 120 includes two clamps 121, each of which is disposed on a corresponding one of the two conveyor belts 100. The two clamps 121 cooperate with each other to clamp the items to be conveyed. The adjustment assembly 140 can adjust the distance between the two clamps 121.

[0062] The clamp assembly 120 can include at least two clamps 121. The distance between the two clamps 121 is adjustable to accommodate items of varying sizes. The distance can include a distance L1 along the spacing direction of the two conveyor belts 100 and a distance L2 along the conveying direction of the conveyor belts 100. When the distance L1 and the distance L2 between the two clamps 121 along the spacing direction of the two conveyor belts 100 match two of the length, width, and height of the items to be conveyed, the items can be securely clamped. The two conveyor belts 100 are then controlled to move synchronously to transport the items.

[0063] The clamp 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 clamps along the spacing direction of the two conveyor belts 100 may refer to the distance between the first limiting sides 121a of the two clamps 121. The spacing distance L2 between the two clamps along the conveying direction of the conveyor belt 100 may refer to the distance between the second limiting sides 121b of the two clamps.

[0064] Optionally, the clamp assembly 120 may further include two auxiliary clamps 122. The two auxiliary clamps 122 may be respectively disposed on the two conveyor belts 100. In addition, the auxiliary clamps 122 and the clamps 121 disposed on the same conveyor belt 100 may be spaced apart. The auxiliary clamps 122 may have a supporting bottom surface 122a for supporting the items to be conveyed.

[0065] Referring to Figure 3, the principle of the adjustment component 140 adjusting the spacing distance L1 between the two clamps 121 along the spacing direction of the two conveyor belts 100 can be: driving the two conveyor belts 100 relatively close to or relatively far away, and further driving the clamps 121 set on the conveyor belts 100 relatively close to or relatively far away, or directly driving the two clamps 121 relatively close to or relatively far away from the conveyor belt 100 along the spacing direction of the conveyor belts 100.

[0066] Referring to Figure 4, the principle of the adjustment component 140 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 asynchronously, thereby causing the clamps 121 set on the conveyor belt 100 to move relative to each other, or directly driving the two clamps 121 to move relative to each other along the conveying direction of the conveyor belt 100.

[0067] As shown in the figure, the 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 placement of the objects to be conveyed, the objects to be conveyed can be placed on the clamps 121 and the auxiliary clamps 122. In other words, preferably, the distance between the two clamps 121 and the auxiliary clamps 122 in the clamp group 120 is greater than the distance L4 between them and less than the distance L3 between two adjacent clamp groups 120.

[0068] In the above manner, the adjustment component 140 can adjust the relative positions of the two clamps 121 so that the clamps 121 can clamp different types of objects to be conveyed, further improving the adaptability of the conveying device 10 to different types of objects to be conveyed.

[0069] According to one or more embodiments of the present application, optionally, two clamps 121 are configured to clamp the items to be conveyed along the spacing direction of the two conveyor belts 100 .

[0070] The adjustment assembly 140 may include a spacing adjustment assembly 141. The spacing adjustment assembly 141 can adjust the spacing distance between the two conveyor belts 100 along the spacing direction, and further adjust the spacing distance L1 between the two clamps 121 along the spacing direction.

[0071] In this manner, the spacing adjustment assembly 141 can be used to adjust the spacing between the two conveyor belts 100, thereby allowing the clamps 121 to accommodate items of varying widths. Furthermore, by adjusting the spacing between the two conveyor belts 100, the spacing adjustment assembly 141 can simultaneously adjust the spacing distance L1 of the clamps 121 of the multiple clamp groups 120 disposed on the conveyor belts 100 along the spacing direction, thereby rapidly adjusting the spacing between the multiple clamp groups 120.

[0072] Referring to FIG. 5 , according to one or more embodiments of the present application, the spacing adjustment assembly 141 optionally includes a first base 1410, two first support frames 1412, and a frame drive mechanism 1414. The two first support frames 1412 are disposed on the first base 1410. The two first support frames 1412 are configured to respectively support a corresponding one of the two conveyor belts 100. The frame drive mechanism 1414 is capable of driving at least one of the two first support frames 1412 to move relative to the first base 1410 in a spacing direction.

[0073] The frame drive mechanism 1414 may include a drive motor and a screw-nut mechanism. The drive motor may have an output shaft to output rotational motion. The screw-nut mechanism may include a screw and a nut. The screw may extend in a direction parallel to the spacing between the two conveyor belts 100. The nut is provided on the screw, which is connected to the output shaft. When the output shaft rotates, it can drive the screw to rotate and drive the nut to perform linear motion along the direction of the screw. A support frame 1412 may be connected to the nut so that it can move along the spacing between the two conveyor belts under the action of the nut.

[0074] In the above manner, the frame driving mechanism 1414 can drive the first supporting frame 1412, thereby driving 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 component 141 can drive at least one of the first supporting frames 1412 to move along the spacing direction through the frame driving mechanism 1414, the two conveyor belts 100 can be moved closer to or farther away from each other.

[0075] According to one or more embodiments of the present application, optionally, the frame driving mechanism 1414 is configured to synchronously drive the two first support frames 1412 to move in opposite directions along the spacing direction.

[0076] In the above manner, the frame driving mechanism 1414 can simultaneously drive the two first support frames 1412 to move away from or toward each other along the spacing direction, thereby quickly adjusting the spacing between the two conveyor belts 100.

[0077] 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 .

[0078] When the frame driving mechanism 1414 can drive the first supporting frame 1412 to slide along the slide rail 1416, the conveyor belt 100 can be driven to move. In this way, the resistance of the first supporting frame 1412 driven by the frame driving mechanism 1414 when moving can be reduced.

[0079] According to one or more embodiments of the present application, the conveyor apparatus 10 optionally 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 configured to respectively support a corresponding one of the two conveyor belts 100. The second support frames 1502 are configured to move relative to the second base 1500 under the drive of the first support frame 1412 driven by the frame drive mechanism 1414.

[0080] The second base 1500 may be provided with a slide rail extending in the spacing direction. When the frame driving mechanism 1414 drives the two conveyor belts 100 to move relative to each other via the first support frame 1412, the second support frame 1502 is also provided with the conveyor belt 100. Therefore, the second support frame 1502 can be driven by the conveyor belt 100 to move synchronously relative to the second base 1500.

[0081] In the above manner, by providing the auxiliary support assembly 150 , the two conveyor belts 100 can be kept roughly parallel when approaching or moving away from each other.

[0082] According to one or more embodiments of the present application, optionally, the number of auxiliary support assemblies 150 is at least two, at least two auxiliary support assemblies 150 are spaced apart 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.

[0083] By adopting the above-mentioned method, the pressure on each auxiliary support assembly 150 and the spacing adjustment assembly 141 can be reduced, thereby making it easier for the spacing adjustment assembly 141 to drive the two conveyor belts 100 closer to or farther away from each other.

[0084] According to one or more embodiments of the present application, optionally, two clamps 121 are configured to clamp the items to be conveyed along the conveying direction of the two conveyor belts 100 .

[0085] The adjustment assembly 140 includes a driving assembly 145. The driving assembly 145 can drive the two conveyor belts 100 in an asynchronous manner to convey the two clamps 121 along the conveying direction, thereby adjusting the interval L2 between the two clamps 121 along the conveying direction.

[0086] The drive assembly 145 driving the two conveyor belts 100 asynchronously may mean that the drive assembly 145 drives the two conveyor belts 100 to move asynchronously. For example, the drive assembly 145 may drive the two conveyor belts 100 to run in opposite directions, or the drive assembly 145 may drive the two conveyor belts 100 to move at different speeds.

[0087] In this way, the drive assembly 145 can control the two conveyor belts 100 to move asynchronously, thereby adjusting the spacing L2 between 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.

[0088] 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.

[0089] 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.

[0090] 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 host computer based on the identification information and matching the identification information. The identification information may be used to represent the size information (e.g., length, width, or height) or model information of the object to be transported, and may be input by a user through the human-machine interface 180 or recognized by an image processing component.

[0091] Optionally, the control signal may 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.

[0092] 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.

[0093] According to one or more embodiments of the present application, the driving assembly 145 optionally 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.

[0094] Optionally, the asynchronous mode 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.

[0095] The switching mechanism can specifically be a clutch. When the switching mechanism does not receive a control signal, the transmission mechanism 147 can directly control the movement of one of the two conveyor belts 100 and control the synchronous movement of the other through the switching mechanism. When the switching mechanism receives a control signal, it disconnects the power connection between the other conveyor belt 100 and the transmission mechanism 147, causing the conveyor belt 100 directly driven by the transmission mechanism 147 to move while the conveyor belt 100 indirectly driven by the switching mechanism remains stationary.

[0096] Optionally, the asynchronous mode includes the switching mechanism switching in response to a control signal so that the two conveyor belts 100 move in opposite directions along the conveying direction and / or move at different speeds.

[0097] The switching mechanism can specifically be a transmission. When the switching mechanism does not receive a control signal, the transmission mechanism 147 can directly control the movement of one of the two conveyor belts 100 and control the synchronous movement of the other through the switching mechanism. When the switching mechanism receives a control signal, the switching mechanism operates in a variable speed mode, allowing the conveyor belt 100 directly driven by the transmission mechanism 147 and the conveyor belt 100 indirectly driven by the transmission mechanism 147 through the switching mechanism to move in opposite directions and / or at different speeds.

[0098] In this way, the two conveyor belts 100 can move in opposite directions and / or at different speeds by controlling the working state of the switching mechanism. In addition, 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.

[0099] According to one or more embodiments of the present application, optionally, the drive assembly 145 is further configured to drive the two conveyor belts 100 to convey the two clamps 121 along the conveying direction in a synchronous manner so that the spacing distance L2 between the two clamps 121 along the conveying direction remains unchanged.

[0100] In this manner, the drive assembly 145 can be synchronized to transport the items being conveyed. When a change in type (changing the type or size of the items being conveyed) is required, the conveyor device 10 typically has no previous or upcoming items being conveyed. In this case, the drive assembly 145 controls the conveyor belt 100 to move asynchronously, thereby achieving the change in type. Once the change in type is complete, the conveyor can resume synchronously.

[0101] According to one or more embodiments of the present application, the conveying device 10 optionally further includes a control system 160. The control system 160 is configured to generate a control signal according to the target spacing distance between the two clamps 121 corresponding to the objects to be conveyed and the actual spacing distance between the two clamps 121.

[0102] The actual spacing distance between the two clamps 121 may refer to the spacing distance between the two clamps 121 before the changeover. The actual spacing distance may include the actual distance along the spacing direction of the two conveyor belts 100 and the actual distance along the conveying direction of the conveyor belts 100. The target spacing distance between the two clamps 121 may refer to the desired spacing distance between the two clamps 121 after the changeover is completed. The target spacing distance may include the target distance along the spacing direction of the two conveyor belts 100 and the target distance along the conveying direction of the conveyor belts 100.

[0103] The principle of generating a control signal based on the target spacing distance between the two clamps 121 and the actual spacing distance between the two clamps 121 can be as follows: obtaining the actual distance and target distance of the two clamps 121 along the spacing direction of the two conveyor belts 100, and calculating the first difference between the actual distance and target distance of the two clamps 121 along the spacing direction of the two conveyor belts 100; obtaining the actual distance and target distance of the two clamps 121 along the conveying direction of the conveyor belt 100, and calculating the second difference between the actual distance and target distance of the two clamps 121 along the conveying direction of the conveyor belt 100, and generating a control signal based on the first difference and the second difference.

[0104] In response to the control signal, the adjustment component 140 can control the spacing adjustment component 141 to drive the two conveyor belts 100 to move relative to each other by a first distance along the spacing direction. The first distance is related to the first difference. The first distance can be equal to or slightly greater than the first difference.

[0105] In response to the control signal, the adjustment component 140 can control the drive component 145 to drive the two conveyor belts 100 to move relative to each other along the conveying direction in an asynchronous manner by a second distance. The second distance can be related to the second difference. The second distance can be equal to or slightly greater than the second difference.

[0106] In the above manner, the conveying device 10 can be used to convey objects of different specifications.

[0107] Referring to Figure 6, according to one or more embodiments of the present application, optionally, the conveying device 10 also includes a human-machine interface 180, which is configured to allow a user to input or specify identification information of the item to be conveyed, and the control system 160 retrieves the target interval distance from a preset database based on the identification information of the item to be conveyed.

[0108] The identification signal may be the model of the object to be transported. The target spacing distance in the preset database may be related to the specifications and dimensions of the object to be transported. The specifications and dimensions may include at least one of length, width, and height.

[0109] The human-machine interface may refer to the interface of an input / output device that establishes communication and exchanges information between a person and the device. The input / output device may include at least one of a keyboard, a display, a mouse, and a touch screen.

[0110] In the above manner, the user can conveniently input identification information (such as the model of the item to be conveyed) through the human-machine interface 180, and the control system 160 can determine the target spacing distance that matches the conveyed item based on the identification information.

[0111] According to one or more embodiments of the present application, the battery assembly system may include conveying equipment and assembly equipment, the conveying equipment is used to convey the structure to be assembled to each workstation of the assembly equipment, and the conveying section of the conveying equipment that conveys the assembly structure to any workstation includes the above-mentioned conveying equipment.

[0113] According to one or more embodiments of the present application, the workstations of the assembly equipment include at least a pole tab welding device, a shell insertion device, a pole tab piercing device, a pole column welding device and a bottom cover welding device; wherein, the pole tab welding device is used to weld multiple pole tab sheets of the electrode assembly to form a pole tab portion; the shell insertion device is used to load the electrode assembly into the shell from the open end; the pole tab piercing device is used to clamp the pole tab portion through the through hole when the electrode assembly is loaded into the shell; the pole column welding device is used to weld the pole tab portion passing through the through hole to the side of the pole away from the accommodating cavity; the bottom cover welding device is used to weld the bottom cover to the open end of the shell.

[0116] The purpose of the tab welding device is to form the tab portion after pre-welding the tab sheet. It can be an ultrasonic welding device that can ensure that the tab is welded in a clamped and stable state. The shell entry device is a pushing mechanism or a clamping mechanism that can stably move the electrode assembly toward the open end of the shell and enter the accommodating cavity through the open end. Similarly, the tab piercing device can adopt a clamping structure or a guiding structure that can guide the tab portion to pass through the through hole smoothly without interfering with the shell. The pole welding device is intended to achieve welding of the tab portion and the pole. It can be a laser welding device. The bottom cover welding device is intended to achieve welding of the circumferential edges of the bottom cover and the open end of the shell. It is also a laser welding device.

[0117] In addition, the assembly equipment is not limited to including a tab welding device, a shell insertion device, a tab piercing device, a pole welding device, and a bottom cover welding device. For example, when the number of electrode assemblies is multiple, for example, two, the assembly equipment also includes a pairing device, which is used to stack multiple electrode assemblies so that the tabs of the two electrode assemblies are roughly opposite each other, so that the conveying structure can convey the matched electrode assemblies to the tab welding device for welding the tabs to facilitate the formation of the tab portion. For example, in order to ensure the reliability of the battery assembly process, dust removal, NG detection stations, etc. can also be added between any two adjacent stations, which is not limited in this embodiment.

The two conveyor belts 100 are arranged side by side and at intervals. Each clamp group 120 includes two clamps 121, and the two clamps 121 are respectively arranged on a corresponding one of the two conveyor belts 100. The two clamps 121 cooperate with each other to clamp the items to be conveyed. The adjustment component 140 is configured to adjust the spacing distance between the two clamps 121 in response to a control signal.

[0119] The spacing adjustment assembly 141 adjusts the spacing distance between the two conveyor belts 100 in the spacing direction in response to a control signal, thereby adjusting the spacing distance L1 between the two clamps 121 in the spacing direction. The spacing adjustment assembly 141 includes a first base 1410, two first support frames 1412, and a frame drive mechanism 1414. The two first support frames 1412 are disposed on the first base 1410 and are configured to support a corresponding one of the two conveyor belts 100. 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.
