Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a separation and feeding device, a feeding control method and a battery production equipment. Background Art

[0002] During the operation of the battery, a sampling component (CCS, Cells Contact System) is needed to collect voltage signals and temperature signals of each battery cell in the battery. The sampling component transmits the sampling signal to the battery management system (Battery Management System) so that the battery management system can monitor the working status of the battery in real time.

[0003] The manifold is an important structural component in the sampling assembly, and the quality of the manifold plays a vital role in the product quality of the sampling assembly.

[0004] In the related art, during the production process of the sampling assembly, when the busbars are loaded, it is easy to take out two busbars that are stuck together and put them into the assembly position, causing abnormal or failure electrical connection of the busbars, making the entire sampling assembly scrapped and reducing the production efficiency of the sampling assembly. Summary of the invention

[0005] The present application aims to solve the problem that two pieces of the busbars that are stuck together are easily loaded and assembled together when loading the busbars, causing abnormal or failed electrical connections of the busbars and reducing the production efficiency of the sampling assembly. To this end, the present application provides a separate loading device, a loading control method and a battery production device.

[0006] In a first aspect, the present application provides a separation and feeding device, comprising:

[0007] A material supply assembly, comprising a material storage channel arranged obliquely relative to a horizontal plane, the material storage channel having a material discharge end, the material storage channel being used to accommodate a plurality of stacked manifolds and discharge the manifolds from the material discharge end;

[0008] A separation assembly, comprising a stopper, a separation groove is formed between the stopper and the discharge end, the separation groove is used to receive the collector discharged from the discharge end, and the stopper is used to stop or release the collector in the separation groove, and the width of the separation groove is greater than or equal to the thickness of one collector and less than the thickness of two collectors;

[0009] The pressing component is used for pressing or releasing the manifold on the material storage channel.

[0010] The separation and feeding device according to the first aspect of the present application has at least the following beneficial effects:

[0011] The separation and loading device of the present application, through the coordinated arrangement of the feeding component, the separation component and the holding component, enables the stacked collectors on the storage channel to enter the separation groove one by one and be released and guided out from the separation groove one by one, so as to load and assemble a single collector, effectively solving the problem of loading two collectors that are stuck together when loading the collector, reducing the production scrap rate of the sampling component, improving the production efficiency of the sampling component, and directly improving the production efficiency of the battery.

[0012] In some embodiments, there is a height difference between the bottom surface of the separation tank and the discharge end.

[0013] Such an arrangement enables the front-end collector to slide relative to the adjacent collector when falling into the separation groove, thereby breaking away from the adhesive contact with the adjacent collector, so that the position of the front-end collector is lower than the adjacent collector and they are misaligned with each other, so that after the stopper releases the collector in the separation groove, the collector in the separation groove can be more smoothly separated from the adjacent collector.

[0014] In some embodiments, the separation component further includes a material guide table, and the stopper, the material guide table and the discharge end together form the separation groove, and the material guide table can guide the conduit to a preset position after the stopper releases the conduit.

[0015] Such an arrangement enables the guide platform to serve as a receiving part of the separation groove, which can stably receive a single collector component, and can also guide the collector component to a preset position after the stopper releases the collector component, thereby improving the loading efficiency of the single collector component.

[0016] In some embodiments, the material guiding platform is inclined relative to the horizontal plane and the inclination angle is adjustable.

[0017] Such arrangement enables the collector in the separation slot to slide freely to a preset position along the inclined material guide platform after being freed from the stopper limit, thereby improving the feeding efficiency of a single collector.

[0018] In some embodiments, the stop member has an initial position for stopping the collector and a release position for releasing the collector, and the stop member can move relative to the material guide table and the material discharge end to adjust the initial position and enable the stop member to switch back and forth between the initial position and the release position.

[0019] Such a configuration, on the one hand, can effectively enable the stopper to switch back and forth between the initial position and the release position, thereby realizing the function of stopping and releasing the collector in the separation groove; on the other hand, it can also adjust the initial position of the stopper, thereby correspondingly adjusting the distance between the stopper and the discharge end, thereby realizing the adjustment of the width of the separation groove, so that the separation groove can adaptively accommodate a single collector of corresponding thickness, so that the separation loading device of the present application can realize the one-by-one loading of collectors of different thicknesses, thereby improving the compatibility and universality of the device.

[0020] In some embodiments, the stopper is configured to be rotatable relative to the guide platform and the discharge end to adjust the width of the separation trough.

[0021] With such a configuration, on the one hand, the width of the separation slot can be adjusted by rotating the stopper relative to the guide platform, so that the separation slot can accommodate the adaptability of the collectors of different specifications and thicknesses, thereby improving the compatibility and universality of the device. On the other hand, the stopper can be directly switched back and forth between the initial position and the release position by rotating the stopper relative to the guide platform, effectively simplifying the overall structure of the device.

[0022] In some embodiments, there are two stoppers, which are arranged opposite to each other. When the two stoppers are in a position perpendicular to the storage channel, the separation groove is closed; when the two stoppers are in a position parallel to the storage channel, the separation groove is opened.

[0023] Such an arrangement enables the stopper to stably limit the stop of the collector in the separation groove or smoothly release the collector in the separation groove, thereby improving the continuity of feeding a single collector, further improving the production efficiency of the sampling assembly, and directly improving the production efficiency of the battery.

[0024] In some embodiments, the separation and loading device also includes a detection mechanism, which is configured to detect whether there is a collector at the preset position, and the stopper is configured to stop or release the collector in the separation groove according to a detection signal of the detection mechanism.

[0025] With such an arrangement, each stacked busbar can be accurately and continuously loaded individually to a preset position, effectively solving the problem of loading two busbars that are stuck together when loading the busbars, reducing the production scrap rate of the sampling assembly, improving the production efficiency of the sampling assembly, and directly improving the production efficiency of the battery.

[0026] In some embodiments, the material storage channel includes two side plates and a bottom plate connected between the two side plates, one end of the bottom plate close to the stopper forms the discharge end, and one end of the side plate close to the stopper protrudes out of the discharge end and abuts against the stopper.

[0027] With such an arrangement, after the collector falls from the discharge end into the separation trough, its four sides are stopped and limited, so that the collector is accurately limited in the separation trough and will not deviate outside the separation trough. This is beneficial for the subsequent material guide platform to accurately guide the collector to the preset position after the stopper releases the collector in the separation trough, thereby improving the accuracy of loading a single collector and further improving the production quality of the sampling assembly.

[0028] In some embodiments, the pressing assembly includes a first driving member and a pressing member connected to an output end of the first driving member, wherein the first driving member is used to drive the pressing member to approach or move away from the material storage channel so that the pressing member presses or releases the conduit on the material storage channel.

[0029] Such an arrangement can automatically hold or release the remaining collectors on the storage channel, so that the stacked collectors on the storage channel enter the separation groove one by one and are guided from the separation groove to the preset position one by one, thereby accurately realizing the loading and assembly of a single collector.

[0030] In some embodiments, the inclination angle of the storage channel relative to the horizontal plane can be adjusted.

[0031] Such arrangement makes the material storage channel inclined relative to the base frame, so that the collectors stacked on the material storage channel can slide along the inclined material storage channel to the material discharge end.

[0032] In some embodiments, the separation and loading device further includes a pushing mechanism, and the pushing mechanism is used to push the conduit on the storage channel to the discharge end.

[0033] Such an arrangement allows the collector on the storage channel to overcome the friction on the surface of the storage channel and accurately move to the discharge end of the storage channel, eliminating the undesirable situation where the collector on the storage channel is difficult to move to the discharge end due to excessive friction.

[0034] In some embodiments, the material supply assembly includes a base frame, and a plurality of the material storage channels are provided on the base frame, and the widths of any two of the material storage channels are different.

[0035] Such an arrangement enables each storage channel to adaptably accommodate the manifolds of corresponding specification thickness. Each group of storage channels, separation components and holding components cooperate to accurately load and assemble the manifolds of corresponding specification thickness one by one, thereby further improving the compatibility and universality of the separation and loading device of the present application.

[0036] In a second aspect, the present application provides a feeding control method, wherein the feeding control method uses the above-mentioned separation feeding device to perform feeding, and the feeding control method comprises the following steps:

[0037] S1, pushing the stacked and arranged confluence pieces on the material storage channel, so that the confluence piece on the material storage channel closest to the stopper falls into the separation groove;

[0038] S2, detecting whether there is a collector at the preset position, if there is no collector at the preset position, controlling the pressing assembly to press the collector on the material storage channel, and then controlling the stopper to release the collector in the separation groove, and guiding the collector released in the separation groove to the preset position;

[0039] If there is a manifold at the preset position, the pressing assembly is controlled to release the manifold on the material storage channel, and step S1 is repeated.

[0040] The feeding control method according to the second aspect of the present application has at least the following beneficial effects:

[0041] The feeding control method of the present application, by using the above-mentioned separation feeding device to implement steps S1 and S2, can accurately and continuously feed each stacked busbar to a preset position separately, effectively solving the problem of loading two busbars that are stuck together when feeding the busbars, reducing the production scrap rate of the sampling components, improving the production efficiency of the sampling components, and directly improving the production efficiency of the battery.

[0042] In a third aspect, the present application provides a battery production equipment, the battery production equipment comprising the separation and loading device described above.

[0043] The battery production equipment according to the third aspect of the present application has at least the following beneficial effects:

[0044] The battery production equipment of the present application, since it is equipped with the above-mentioned separation and loading device, also has the same technical effect brought by the above-mentioned separation and loading device, that is, through the coordinated arrangement of the feeding component, the separation component and the holding component, the stacked collectors on the storage channel enter the separation groove one by one and are released and guided out from the separation groove, so that the single collector is loaded and assembled, which effectively solves the problem of loading two collectors that are stuck together when loading the collector, reduces the production scrap rate of the sampling component, improves the production efficiency of the sampling component, and directly improves the production efficiency of the battery.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0059] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0060] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. 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 vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0061] The battery is composed of one or more battery cells. For each battery, the battery cells that make up the battery can be connected in series, in parallel, or in mixed connection. Mixed connection means that the battery cells are connected in series and in parallel.

[0062] A battery cell is the smallest unit that makes up a battery. In the structure of a battery cell, it includes a shell, an electrolyte, and an electrode assembly. The electrode assembly is the component that undergoes electrochemical reactions in the battery cell. The electrode assembly includes a positive electrode sheet, a negative electrode sheet, and a separator. The shell may include one or more electrode assemblies. The electrode assembly is mainly formed by winding or stacking a positive electrode sheet and a negative electrode sheet, and a separator is usually provided between the positive electrode sheet and the negative electrode sheet.

[0063] The shell is a structure with one end open and a hollow interior. The electrode assembly is arranged inside the shell, and the end cover is arranged at the opening of the shell. The internal environment of the battery cell is formed by covering the opening with the end cover. Of course, the end cover and the shell can also be integrated. Specifically, the end cover and the shell can form a common connection surface before other components are put into the shell. When the interior of the shell needs to be encapsulated, the end cover is closed with the shell. The shell can be of various shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, a hexagonal prism, etc. Specifically, the shape of the shell can be determined according to the specific shape and size of the electrode assembly. The shell can be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not impose any special restrictions on this.

[0064] During the operation of the battery, in order to enable the battery to operate within the specified voltage and temperature ranges, a sampling component (CCS, Cells Contact System) is required to collect voltage and temperature signals from each battery cell in the battery. The sampling component transmits the sampling signal to the battery management system (Battery Management System) so that the battery management system can monitor the working status of the battery in real time.

[0065] The sampling assembly includes wiring harness isolation plates, output pole assemblies (output pole copper bars, output pole aluminum bars), aluminum bars, connectors and other structural components. The output pole assemblies and aluminum bars are collectively referred to as bus-bars (or bus-bars). The bus-bars are used to connect multiple battery cells in series, parallel or mixed connection. The quality of the bus-bars plays a vital role in the product quality of the sampling assembly.

[0066] In the related art, during the production process of the sampling assembly, the loading of the collector is usually done manually. Since the collectors are generally delivered in a stacked form, it is easy to take out two collectors that are stuck together and place them in the assembly position when manually picking up the materials, which can easily cause abnormal or failure of the electrical connection of the collector, making the entire sampling assembly scrapped and reducing the production efficiency of the sampling assembly.

[0067] Based on the problem that two convergent pieces that are stuck together are easily loaded and assembled together when loading the convergent pieces during the current production process of the sampling assembly, resulting in abnormal or failed electrical connections of the convergent pieces and reduced production efficiency of the sampling assembly, one or more embodiments of the present application provide a separation loading device, through the coordinated arrangement of the feeding assembly 100, the separation assembly 200 and the holding assembly 300, so that the stacked convergent pieces 500 on the storage channel 110 enter the separation groove 230 one by one and are released and guided out from the separation groove 230 one by one, so that a single convergent piece 500 is loaded and assembled, effectively solving the problem that two convergent pieces 500 that are stuck together are easily loaded and assembled together when loading the convergent pieces, thereby reducing the production scrap rate of the sampling assembly, improving the production efficiency of the sampling assembly, and directly improving the production efficiency of the battery.

[0068] See also Figure 1 and Figure 2 An embodiment of the present application provides a separation and loading device, which includes a feeding component 100, a separation component 200 and a holding component 300.

[0069] The material supply assembly 100 includes a material storage channel 110 having a material discharge end 111 . The material storage channel 110 is used to accommodate a plurality of stacked manifolds 500 and discharge the manifolds 500 from the material discharge end 111 .

[0070] The separation assembly 200 includes a stopper 220 , and a separation groove 230 is formed between the stopper 220 and the discharge end 111 . The separation groove 230 is used to receive the collector 500 discharged from the discharge end 111 , and the stopper 220 is used to stop or release the collector 500 in the separation groove 230 .

[0071] The pressing assembly 300 is used to press or release the manifold 500 on the material storage channel 110 .

[0072] It should be noted that the feed assembly 100 refers to a structure for providing initial busbar material. The busbar is in block shape, and the initial busbar material refers to a plurality of busbars 500 arranged in a stack, that is, a stack of busbars. It is easy to understand that after the busbars 500 are produced and shipped, they are stored, transported and fed in a stacked arrangement.

[0073] Multiple collectors 500 are stacked and arranged in a preset track such as a straight line, a curve, or a ring. Correspondingly, the shape of the storage channel 110 is adapted to the arrangement track of the multiple collectors 500, which corresponds to a straight channel, a curve channel, an annular channel, etc., so as to accommodate multiple stacked collectors 500 in an adaptive manner.

[0074] Exemplarily, after the busbars 500 are produced, multiple busbars 500 are stacked and arranged along a straight track, and the storage channel 110 corresponds to a straight channel. That is, when multiple busbars 500 are accommodated on the storage channel 110, multiple busbars 500 are stacked and arranged along the extension track of the storage channel 110.

[0075] The initially stacked busbars 500 may be placed on the material storage channel 110 manually or by a robot to achieve initial material supply to the initially stacked busbars 500 .

[0076] The storage channel 110 can be arranged to be inclined at a certain angle relative to the horizontal plane, so that the multiple stacked collectors 500 thereon can automatically slide along the inclined storage channel 110 to the discharge end 111 and fall into the separation tank 230 from the discharge end 111. The discharge end 111 can be understood as the end of the storage channel 110.

[0077] Of course, a corresponding push mechanism 400 may also be provided on the material storage channel 110, and the output end of the push mechanism 400 acts on the surface of the manifold 500 on the material storage channel 110 that is farthest from the stopper 220, and by intermittently pushing the manifold 500, all manifolds 500 are pushed to the material discharge end 111 in sequence. The push mechanism 400 may be, but is not limited to, a matching structure of a cylinder, a slider, and a ball screw mechanism.

[0078] In the separation assembly 200, the stopper 220 refers to a structure for stopping or releasing the collector 500. The stopper 220 is configured to be able to rotate or move relative to the discharge end 111 so as to adjust the position of the stopper 220 relative to the discharge end 111 so that the stopper 220 stops or releases the collector 500 in the separation groove 230.

[0079] It should be understood that when the stopper 220 is in the initial position, the size of the separation groove 230 formed between the stopper 220 and the discharge end 111 can only accommodate a single collector 500, and it is difficult to accommodate two or more collectors 500, so that the collectors 500 of the storage channel 110 fall into the separation groove 230 one by one from the discharge end 111. When the stopper 220 is in the release position, the stopper 220 can separate the collectors 500 in the separation groove 230.

[0080] The pressing component 300 refers to a structure capable of pressing or releasing at least one collector 500 on the storage channel 110 . The pressing component 300 can be disposed above the storage channel 110 to press or release 500 on the storage channel 110 by lifting or lowering relative to the storage channel 110 .

[0081] The following describes the loading process of the single manifold 500 in combination with the coordinated actions of the material storage channel 110, the separation assembly 200 and the pressing assembly 300:

[0082] The stopper 220 is in the initial position. At this time, a separation groove 230 is formed between the stopper 220 and the discharge end 111 of the storage channel 110 . The separation groove 230 can only accommodate a single manifold 500 .

[0083] The storage channel 110 discharges the multiple collectors 500 stacked thereon from the discharge end 111. Since the separation tank 230 can only accommodate a single collector 500, the collector 500 at the front end of the storage channel 110 falls into the separation tank 230 from the discharge end 111. At this time, the stopper 220 constitutes a wall surface of the separation tank 230, which plays a role in stopping and limiting the collector 500 in the separation tank 230, so that the collector 500 in the separation tank 230 remains stationary at this time, and the remaining collectors 500 on the storage channel 110 are stopped and limited by the collector 500 in the separation tank 230 and cannot continue to be discharged from the discharge end 111. In this way, the collector 500 at the front end of the storage channel 110 is separated from the adjacent adhered collectors 500.

[0084] When the separation groove 230 receives a single collector 500 discharged from the discharge end 111, the collector 500 has been separated from the storage channel 110. At this time, the pressing assembly 300 presses and limits the remaining collectors 500 on the storage channel 110 to keep the remaining collectors 500 on the storage channel 110 stationary.

[0085] Then, after the stopper 220 rotates a certain angle or moves a certain distance relative to the discharge end 111, the stopper 220 moves to the release position to open the separation groove 230, release the stop limit on the collector 500 in the separation groove 230, and release the collector 500, thereby releasing and exporting the single collector 500. In this way, the separation and release of the single collector 500 is achieved, and the single collector 500 released from the separation groove 230 can be loaded to the assembly position manually or by a robot. In this way, the loading of the single collector 500 is achieved.

[0086] After the stopper 220 releases the collector 500 in the separation groove 230, the stopper 220 is reset to the initial position, and the holding assembly 300 releases the remaining collectors 500 on the storage channel 110, and the frontmost collector 500 on the storage channel 110 falls into the separation groove 230 again, and so on.

[0087] In this way, through the coordinated arrangement of the feeding component 100, the separation component 200 and the holding component 300, the stacked collectors 500 on the storage channel 110 enter the separation groove 230 one by one and are released and guided out from the separation groove 230 one by one, so that the single collector 500 can be loaded and assembled, which effectively solves the problem of loading two collectors 500 that are stuck together when loading the collector, reduces the production scrap rate of the sampling component, improves the production efficiency of the sampling component, and directly improves the production efficiency of the battery.

[0088] In some embodiments of the present application, see Figure 2 and Figure 3 , the width of the separation groove 230 is greater than or equal to the thickness of one busbar 500 and less than the thickness of two busbars 500 .

[0089] It should be noted that the width of the separation groove 230 refers to the distance between the initial position of the stopper 220 and the discharge end 111 of the storage channel 110, and the initial position of the stopper 220 refers to the position where the stopper 220 can serve as a wall of the separation groove 230 to stop and limit the collector 500 in the separation groove 230.

[0090] It can be understood that the width direction of the separation groove 230 is consistent with the thickness direction of the manifold 500 on the storage channel 110 .

[0091] It is easy to understand that by setting the width of the separation groove 230 to be greater than or equal to the thickness of one runner 500 and less than the thickness of two runners 500, the separation groove 230 can be large enough to accommodate only a single runner 500, and cannot accommodate two or more runners 500, thereby effectively overcoming the problem of two runners 500 that are stuck together entering the separation groove 230 together and being loaded in a stuck state.

[0092] Exemplarily, the width of the separation groove 230 is equal to the thickness of the single current collector 500 , so that the size of the separation groove 230 is just suitable for accommodating the single current collector 500 .

[0093] In some embodiments of the present application, see Figure 1 , Figure 2 and Figure 3 , there is a height difference between the bottom surface of the separation tank 230 and the discharge end 111 .

[0094] Specifically, the separation component 200 further includes a material guiding platform 210 , which is docked at the material discharging end 111 of the material storage channel 110 , and there is a height difference between the material guiding plane of the material guiding platform 210 and the material discharging end 111 of the material storage channel 110 .

[0095] When the stopper 220 is in the initial position, the stopper 220, the guide platform 210 and the discharge end 111 enclose a separation groove 230, and the separation groove 230 is in the shape of a step groove relative to the discharge end 111. The bottom surface of the separation groove 230 is the planar portion of the guide platform 210 defined between the stopper 220 and the discharge end 111, so that a height difference is formed between the bottom surface of the separation groove 230 and the discharge end 111.

[0096] In the process of the front-end collector 500 on the storage channel 110 falling from the discharge end 111 into the separation trough 230, thanks to the height difference between the bottom surface of the separation trough 230 and the discharge end 111, the front-end collector 500 can slide relative to the adjacent collector 500 when falling into the separation trough 230, thereby breaking away from the adhesive contact with the adjacent collector 500, making the position of the front-end collector 500 lower than the adjacent collector 500 and staggered with each other, so that after the stopper 220 releases the collector 500 in the separation trough 230, the collector 500 in the separation trough 230 can be more smoothly separated from the adjacent collector.

[0097] In addition, thanks to the height difference between the bottom surface of the separation groove 230 and the discharge end 111, the top position of the collector 500 that falls into the separation groove 230 is lower than the top position of the remaining collectors 500 on the storage channel 110. In this way, when the pressing component 300 limits the remaining collectors 500 on the storage channel 110, it only needs to press and hold the top surface of the frontmost collector 500 on the storage channel 110 to achieve the limitation on the storage channel 110, thereby reducing the overall structural cost of the pressing component 300 and simplifying the structural design of the entire separation and feeding device.

[0098] In some embodiments of the present application, see Figure 1 and Figure 2 The separation component 200 further includes a guide platform 210 , a stopper 220 , the guide platform 210 and a discharge end 111 together form a separation slot 230 , and the guide platform 210 can guide the conduit 500 to a preset position after the stopper 220 releases the conduit 500 .

[0099] Specifically, the guide platform 210 is a structure capable of receiving the collector 500 and guiding the collector 500 to a preset position. The guide platform 210 is docked at the discharge end 111 of the storage channel 110 and there is a height difference between the guide plane of the guide platform 210 and the discharge end 111 of the storage channel 110.

[0100] The guide platform 210 can be set to be inclined at a certain angle relative to the horizontal plane, so that the collector 500 on the guide platform 210 can slide freely along the guide platform 210 to a preset position without being stopped and limited by the stopper 220. The preset position can be understood as the final loading position of the collector 500. After the collector 500 is guided to the preset position by the guide platform 210, the collector 500 at the preset position can be loaded to the assembly position manually or by a robot, so that the loading of the collector 500 is realized.

[0101] It is not difficult to understand that, through the setting of the material guide platform 210, the stopper 220, the material guide platform 210 and the discharge end 111 are enclosed to form a separation groove 230, so that the material guide platform 210 serves as a receiving part of the separation groove 230, which can stably receive the single-block collector 500, and can also guide the collector 500 to a preset position after the stopper 220 releases the collector 500, thereby improving the loading efficiency of the single-block collector 500.

[0102] In some embodiments of the present application, see Figure 2 The stopper 220 has an initial position for stopping the collector 500 and a release position for releasing the collector 500. The stopper 220 can move relative to the material guide platform 210 and the material discharge end 111 to adjust the initial position and switch the stopper 220 back and forth between the initial position and the release position.

[0103] Specifically, the stop member 220 is slidably installed on the material guide table 210 so as to be able to slide freely on the material guide table 210. Exemplarily, the stop member 220 is slidably installed on the material guide table 210 through a second driving member (not shown in the figure). The second driving member can be an XY two-axis sliding platform. The second driving member drives the stop member 220 to slide along the length and width directions of the material guide table 210.

[0104] It should be noted that the length direction of the material guide platform 210 coincides with the thickness direction of the collector 500 on the material storage channel 110 , and the width direction of the material guide platform 210 coincides with the length direction of the collector 500 on the material storage channel 110 and also coincides with the width direction of the material storage channel 110 .

[0105] When the stopper 220 is in the initial position, the stopper 220 is perpendicular to the storage channel 110 and is distributed opposite to the discharge end 111 of the storage channel 110. At this time, the stopper 220 is also parallel to the collector 500. At this time, the stopper 220, the discharge end 111 and the guide platform 210 enclose a rectangular separation groove 230 with an upward opening.

[0106] When it is necessary to export the collector 500 in the separation groove 230, the stopper 220 can move along the width direction of the guide platform 210, so that the stopper 220 opens the wall of the separation groove 230 opposite to the discharge end 111, and the stopper 220 is in the release position, disengaging from the stopper of the collector 500 in the separation groove 230, and cooperating with the guiding function of the guide platform 210, the collector 500 in the separation groove 230 is released to the preset position, thereby realizing the loading of a single collector 500.

[0107] Likewise, the stopper 220 moves along the width direction of the material guiding platform 210 and returns to the initial position.

[0108] In addition, it should be noted that in the production process of the sampling assembly, various specifications of the collectors 500 are loaded into multiple assembly positions for processing and assembly, and the thicknesses of the collectors 500 of different specifications are different (the specifications of the collectors on each stack of collectors are the same, that is, the thickness is the same).

[0109] Based on this, during the initial debugging, the separation and loading device of the present application can change the initial position of the stopper 220 by moving the stopper 220 along the length direction of the guide platform 210 according to the thickness of the collector 500 to be loaded, thereby correspondingly adjusting the distance between the stopper 220 and the discharge end 111, thereby adjusting the width of the separation groove 230, so that the separation groove 230 can adaptively accommodate a single collector 500 of corresponding thickness.

[0110] In this way, the separation and loading device of the present application can load the collectors 500 of different thicknesses one by one, thereby improving the compatibility and universality of the device.

[0111] Of course, in other embodiments, the stopper 220 can be rotatably mounted on the material guide platform 210 , so that the stopper 220 can switch back and forth between the initial position and the release position by rotating relative to the material guide platform 210 and the discharge end 111 .

[0112] Similarly, during the early debugging of the separation loading device, the stopper 220 can be rotated based on the thickness of the collector 500 to be loaded, so that an angle is set between the stopper 220 and the discharge end 111, so that the initial position of the stopper 220 is adjusted to a distance between the stopper 220 and the discharge end 111 that can just accommodate a single collector 500 of corresponding thickness.

[0113] It should be noted that the thickness difference between the collectors 500 of different specifications is relatively small. Therefore, the angle at which the stopper 220 needs to be rotated is relatively small. When the stopper 220 is in a position with an angle with the discharge end 111, it can also stop the collector 500 in the separation groove 230.

[0114] It is not difficult to understand that by setting the stop member 220 to be movable relative to the guide platform 210 and the discharge end 111, on the one hand, the stop member 220 can be effectively switched back and forth between the initial position and the release position, thereby realizing the function of stopping and releasing the collector 500 in the separation groove 230; on the other hand, the initial position of the stop member 220 can be adjusted, thereby correspondingly adjusting the distance between the stop member 220 and the discharge end 111, thereby realizing the adjustment of the width of the separation groove 230, so that the separation groove 230 can adaptively accommodate a single collector 500 of corresponding thickness, so that the separation loading device of the present application can realize the one-by-one loading of collectors 500 of different thicknesses, thereby improving the compatibility and universality of the device.

[0115] In some embodiments of the present application, see Figure 2 and Figure 3 The stopper 220 is configured to be rotatable relative to the material guiding platform 210 and the material discharging end 111 to adjust the width of the separation groove 230 .

[0116] Specifically, the separation component 200 also includes a rotating shaft 240 and a third driving member (not shown in the figure). The stop member 220 is rotatably installed on the material guide table 210 via the rotating shaft 240. The output end of the third driving member is connected to the rotating shaft 240 to drive the stop member 220 to rotate relative to the material guide table 210 and the discharge end 111 via the rotating shaft 240. The third driving member can be a rotating driving structure such as a motor.

[0117] It should be noted that, during the early debugging process of the separation and loading device of the present application, the initial position of the stopper 220 can be adjusted according to the thickness of the collector 500 to be loaded, so as to adjust the width of the separation groove 230, so that the stopper 220 can be rotated to a distance between it and the discharge end 111 that can just accommodate a single collector 500 of corresponding thickness, thereby achieving adaptation to collectors 500 of different thicknesses.

[0118] In addition, when it is necessary to release the collector 500 in the separation groove 230, the third driving member drives the stopper 220 to rotate a certain angle relative to the guide platform 210 and the discharge end 111 by driving the rotating shaft 240 to rotate, so that the stopper 220 rotates to the release position where the separation groove 230 is fully opened, and cooperates with the guiding function of the guide platform 210 to release the collector 500 in the separation groove 230 to the preset position, thereby realizing the loading of a single collector 500.

[0119] It is not difficult to understand that by configuring the stopper 220 to be rotatable relative to the material guide platform 210 and the material discharge end 111, on the one hand, the width of the separation slot 230 can be adjusted by rotating the stopper 220 relative to the material guide platform 210, so that the separation slot 230 can accommodate the adaptability of the collectors 500 of different specifications and thicknesses, thereby improving the compatibility and universality of the device. On the other hand, by rotating the stopper 220 relative to the material guide platform 210, the stopper 220 can be directly switched back and forth between the initial position and the release position, effectively simplifying the overall structure of the device.

[0120] In some embodiments of the present application, see Figure 1 , Figure 2 and Figure 3 The stoppers 220 have two stoppers 220 that are disposed opposite to each other. When the two stoppers 220 are at a position perpendicular to the material storage channel 110 , the separation groove 230 is closed. When the two stoppers 220 are at a position parallel to the material storage channel 110 , the separation groove 230 is opened.

[0121] Specifically, the stopper 220 is constructed as a stop block. When the two stoppers 220 are in the initial position, the two stoppers 220 are on the same plane, perpendicular to the storage channel 110, and parallel to the collector 500. At the same time, the length of the collector 500 is less than the length of the connecting line of the two stoppers 220, and the length direction of the collector 500 corresponds to the width direction of the storage channel 110.

[0122] After the two stoppers 220 rotate 90° relative to the initial position, they are in a position parallel to the storage channel 110. At this time, the separation groove 230 is fully opened, and the conduit 500 in the separation groove 230 is no longer limited by the stoppers 220 and is dumped onto the guide platform 210 and is smoothly guided to the preset position by the guide platform 210.

[0123] Such a configuration enables the stopper 220 to stably stop the collector 500 in the separation groove 230 or smoothly release the collector 500 in the separation groove 230, thereby improving the continuity of feeding a single collector 500, further improving the production efficiency of the sampling assembly, and directly improving the production efficiency of the battery.

[0124] In some embodiments of the present application, see Figure 2 and Figure 3 The storage channel 110 includes two side plates 112 and a bottom plate 113 connected between the two side plates 112 , and one end of the bottom plate 113 close to the stopper 220 forms a discharge end 111 , and one end of the side plate 112 close to the stopper 220 protrudes from the discharge end 111 and abuts against the stopper 220 .

[0125] It should be noted that the line between the two side plates 112 corresponds to the width direction of the material storage channel 110, and also corresponds to the length direction of the busbar 500. The height direction of the side plate 112 corresponds to the width direction of the busbar 500. The spacing between the two side plates 112 is slightly larger than the length of the busbar 500, and the top of the side plate 112 is lower than the top of the busbar 500, so that the pressing assembly 300 can effectively contact and press the busbar 500 on the material storage channel 110.

[0126] It can be understood that when the stopper 220 is in the initial position, since one end of the side plate 112 close to the stopper 220 protrudes from the discharge end 111 and abuts against the stopper 220, the separation groove 230 formed by the stopper 220, the discharge end 111 and the guide platform 210 is a rectangular groove with an opening facing upward, and the two ends of the separation groove 230 in the width direction are respectively limited by the stopper 220 and the discharge end 111 on the bottom plate 113, and the two ends of the separation groove 230 in the length direction are respectively limited by the two side plates 112 protruding from the bottom plate 113.

[0127] In this way, after the collector 500 falls from the discharge end 111 into the separation groove 230, it is stopped and limited on all four sides, so that the collector 500 is accurately limited in the separation groove 230 and will not deviate outside the separation groove 230. This is beneficial for the subsequent guide platform 210 to accurately guide the collector 500 to the preset position after the stopper 220 releases the collector 500 in the separation groove 230, thereby improving the accuracy of loading a single collector 500 and further improving the production quality of the sampling component.

[0128] In some embodiments of the present application, see Figure 2 and Figure 3The pressing assembly 300 includes a first driving member 310 and a pressing member 320 connected to the output end of the first driving member 310. The first driving member 310 is used to drive the pressing member 320 to approach or move away from the storage channel 110 so that the pressing member 320 presses or releases the conduit 500 on the storage channel 110.

[0129] Specifically, the first driving member 310 may be a cylinder, a hydraulic cylinder, an electric push rod, etc., or may be a combination of a motor and a transmission assembly, and the transmission assembly may be a bidirectional lead screw, a gear rack, etc. Exemplarily, the first driving member 310 may be a cylinder, which has a simple structure and is easy to operate.

[0130] The holding member 320 is constructed as a holding block, which is located directly above the discharge end 111 of the storage channel 110. By holding the single manifold 500 at the discharge end 111, the stop and limit of all manifolds on the storage channel 110 is achieved, simplifying the structural design.

[0131] It is not difficult to understand that, through the cooperative arrangement of the first driving member 310 and the holding member 320, the remaining collectors 500 on the storage channel 110 can be automatically held or released, so that the stacked collectors 500 on the storage channel 110 enter the separation groove 230 one by one and are guided from the separation groove 230 to the preset positions one by one, thereby accurately realizing the loading and assembly of a single collector 500.

[0132] In some embodiments of the present application, see Figure 1 The material storage channel 110 is inclined relative to the horizontal plane and the inclination angle can be adjusted.

[0133] Specifically, the feeding assembly 100 also includes a base frame 120, with the plane where the base frame 120 is located as the horizontal plane, the storage channel 110 is hinged on the base frame 120, and the base frame 120 is installed with a fourth driving member 130. The output end of the fourth driving member 130 is connected to the storage channel 110 to drive the storage channel 110 to rotate around the hinged end with the base frame 120 at a certain angle and then remain fixed, so that the storage channel 110 is inclined relative to the base frame 120, so that the collector 500 stacked on the storage channel 110 can slide along the inclined storage channel 110 to the discharge end 111.

[0134] The driving connection between the fourth driving member 130 and the material storage channel 110 can adjust the inclination angle of the material storage channel 110 relative to the horizontal plane to meet the needs of the site. For example, the fourth driving member 130 can be a gas spring structure.

[0135] In some embodiments of the present application, see Figure 1 and Figure 4 The separation and loading device further includes a pushing mechanism 400 , which is used to push the conduit 500 on the storage channel 110 to the discharge end 111 .

[0136] Specifically, the pushing mechanism 400 includes a fifth driving member 410 and a pushing block 420 . The output end of the fifth driving member 410 is connected to the pushing block 420 to drive the pushing block 420 to move along the storage channel 110 . The pushing block 420 abuts against the collector 500 on the storage channel 110 that is farthest from the stopper 220 .

[0137] Through the pushing action of the pushing mechanism 400 on the collector 500 on the storage channel 110, the collector 500 on the storage channel 110 can overcome the friction on the surface of the storage channel 110 and accurately move to the discharge end 111 of the storage channel 110, thereby eliminating the undesirable situation that the collector 500 on the storage channel 110 is difficult to move to the discharge end 111 due to excessive friction.

[0138] In some embodiments of the present application, see Figure 1 and Figure 5 The material guiding platform 210 is inclined relative to the horizontal plane and the inclination angle can be adjusted.

[0139] Specifically, the material guide platform 210 can be directly connected to the bottom of the material storage channel 110. During the process of rotating and adjusting the material storage channel 110 to be inclined relative to the horizontal plane, the material storage channel 110 drives the material guide platform 210 to rotate synchronously, thereby realizing synchronous adjustment of the material guide platform 210.

[0140] By setting the guide platform 210 to a position inclined relative to the horizontal plane, the collector 500 in the separation groove 230 can slide freely along the inclined guide platform 210 to a preset position after being stopped by the stopper 220, thereby improving the loading efficiency of a single collector 500.

[0141] In some embodiments of the present application, the separation and loading device also includes a detection mechanism (not shown in the figure), which is configured to detect whether there is a collector 500 at a preset position, and the stopper 220 is configured to be able to stop or release the collector 500 in the separation groove 230 according to the detection signal of the detection mechanism.

[0142] Specifically, the separation and feeding device further includes a controller (not shown in the figure), and the stopper 220 is driven by the third driving member to rotate relative to the material guide platform 210 to stop or release the confluence member 500 in the separation groove 230. The detection mechanism is arranged just above the preset position, and the detection mechanism can be, but is not limited to, an optical camera, an infrared detector and other structures, and the third driving member, the detection mechanism, the first driving member 310 of the pressing assembly 300 and the fifth driving member 410 of the pushing mechanism 400 are all electrically connected to the controller.

[0143] When the detection mechanism detects that there is no collector 500 at the preset position, it means that the collector 500 in the separation groove 230 has not been discharged yet. At this time, the controller controls the first driving member 310 to operate, so that the first driving member 310 drives the holding member 320 to move toward the collector 500 near the discharge end 111 and press on the collector 500, thereby realizing the stop limit of all the collectors 500 on the storage channel 110.

[0144] Then, the controller controls the third driving member to drive the stopper 220 to rotate to the release position, so that the collector 500 in the separation groove 230 is preset by the guide table 210, thereby achieving accurate loading of a single collector 500.

[0145] When the detection mechanism detects that there is a collector 500 at the preset position, it means that the collector 500 in the separation groove 230 has been discharged. At this time, the controller controls the third driving member to operate, so that the third driving member drives the stop member 220 to reset and rotate to the initial position, and then controls the first driving member 310 to operate, so that the first driving member 310 drives the holding member 320 to move away from the collector 500 on the discharge end 111, so as to release the stop limit of all the collectors 500 on the storage channel 110.

[0146] Then, the controller controls the fifth driving member 410 to move, so that the fifth driving member 410 drives the push block 420 to push the converging member 500 on the storage channel 110 that is farthest from the stopper 220, so that the converging member 500 on the storage channel 110 that is closest to the stopper 220 falls from the discharge end 111 into the separation groove 230. Then, the controller controls the first driving member 310 to move, so that the first driving member 310 drives the pressing member 320 to press the converging member 500 on the discharge end 111 again, and stops and limits all the converging members 500 on the storage channel 110 again.

[0147] In this way, each stacked busbar 500 is accurately and continuously loaded to the preset position, which effectively solves the problem of loading two busbars 500 that are stuck together when loading the busbars, reduces the production scrap rate of the sampling assembly, improves the production efficiency of the sampling assembly, and directly improves the production efficiency of the battery.

[0148] In some embodiments of the present application, see Figure 1 and Figure 5 The feeding assembly 100 includes a base frame 120 , on which a plurality of material storage channels 110 are disposed, and the widths of any two material storage channels 110 are different.

[0149] Specifically, each material storage channel 110 corresponds to a set of separation components 200 and a pressing component 300 .

[0150] Such an arrangement enables each storage channel 110 to adaptively accommodate a manifold 500 of corresponding specification thickness. Each group of storage channels 110, separation components 200 and holding components 300 cooperate to accurately load and assemble manifolds 500 of corresponding specification thickness one by one, thereby further improving the compatibility and universality of the separation and loading device of the present application.

[0151] In addition, see Figure 1 , Figure 2 and Figure 6 The embodiment of the present application further provides a feeding control method, which uses the above-mentioned separation feeding device to feed materials, and the feeding control method includes the following steps:

[0152] S1, pushing the stacked and arranged flow collectors 500 on the material storage channel 110, so that the flow collector 500 on the material storage channel 110 closest to the stopper 220 falls into the separation groove 230;

[0153] S2, detecting whether there is a collector 500 at the preset position. If there is no collector 500 at the preset position, controlling the pressing assembly 300 to press the collector 500 on the material storage channel 110, and then controlling the stopper 220 to release the collector 500 in the separation groove 230, and guiding the collector 500 released from the separation groove 230 to the preset position;

[0154] If there is a manifold 500 at the preset position, the pressing assembly 300 is controlled to release the manifold 500 on the material storage channel 110 , and step S1 is repeated.

[0155] It should be noted that, as mentioned above, when implementing step S1 , the manifold 500 on the material storage channel 110 , that is, the manifold 500 closest to the stopper 220 on the material storage channel 110 , can be pushed by the pushing mechanism 400 to fall into the separation groove 230 .

[0156] When step S2 is implemented, a detection mechanism is used to detect whether there is a current collector 500 at the preset position.

[0157] The preset position can be understood as the final loading position of the busbar 500 , and the aforementioned guide platform 210 can guide the busbar 500 to the preset position after the stopper 220 releases the busbar 500 .

[0158] When the detection mechanism detects that there is no collector 500 at the preset position, it means that the collector 500 in the separation groove 230 has not been discharged yet. At this time, the controller controls the first driving member 310 to operate, so that the first driving member 310 drives the holding member 320 to move toward the collector 500 near the discharge end 111 and press on the collector 500, thereby realizing the stop limit of all the collectors 500 on the storage channel 110.

[0159] Then, the controller controls the third driving member to drive the stopper 220 to rotate to the release position, so that the collector 500 in the separation groove 230 is preset by the guide table 210, thereby achieving accurate loading of a single collector 500.

[0160] When the detection mechanism detects that there is a collector 500 at the preset position, it means that the collector 500 in the separation groove 230 has been discharged. At this time, the controller controls the third driving member to operate, so that the third driving member drives the stop member 220 to reset and rotate to the initial position, and then controls the first driving member 310 to operate, so that the first driving member 310 drives the holding member 320 to move away from the collector 500 on the discharge end 111, so as to release the stop limit of all the collectors 500 on the storage channel 110.

[0161] Then, the controller controls the fifth driving member 410 to move, so that the fifth driving member 410 drives the push block 420 to push the converging member 500 on the storage channel 110 that is farthest from the stopper 220, so that the converging member 500 on the storage channel 110 that is closest to the stopper 220 falls from the discharge end 111 into the separation groove 230. Then, the controller controls the first driving member 310 to move, so that the first driving member 310 drives the pressing member 320 to press the converging member 500 on the discharge end 111 again, and stops and limits all the converging members 500 on the storage channel 110 again.

[0162] In this way, each stacked busbar 500 is accurately and continuously loaded to the preset position, which effectively solves the problem of loading two busbars 500 that are stuck together when loading the busbars, reduces the production scrap rate of the sampling assembly, improves the production efficiency of the sampling assembly, and directly improves the production efficiency of the battery.

[0163] It is not difficult to understand that the loading control method of the embodiment of the present application, by using the above-mentioned separate loading device to implement steps S1 and S2, can accurately and continuously load each stacked busbar 500 separately to a preset position, effectively solving the problem of loading two busbars 500 that are stuck together when loading the busbars, reducing the production scrap rate of the sampling assembly, improving the production efficiency of the sampling assembly, and directly improving the production efficiency of the battery.

[0164] In addition, based on the same concept as the above-mentioned separation and loading device, an embodiment of the present application further provides a battery production equipment, and the battery production equipment includes the above-mentioned separation and loading device.
