[0024] Embodiment of the present application

[0025] The battery connection assembly positioning method provided by the present application can be applied in the application environment as shown in FIG. 1. The processing device can include a processor 102 and a memory 104, and the memory 104 can be used to store CCS assembly design drawing data and CCS projection pattern data. The processor 102 can be used to obtain CCS assembly design drawing data corresponding to a battery module to be assembled; generate a CCS projection pattern according to the CCS assembly design drawing data, and project the CCS projection pattern on a first table; and position and place a connection assembly to be positioned on the first table according to the CCS projection pattern. The processing device can further include a display 106, which can display CCS assembly design drawing data and CCS projection pattern data through a graphical interface. For example, the processing device can be a projection control device.

[0026] In one embodiment, as shown in FIG. 2, a battery connection assembly positioning method is provided. Taking the processor 102 in FIG. 1 as an example, the method includes the following steps:

[0027] In step S210, CCS assembly design drawing data corresponding to a battery module to be assembled is obtained.

[0028] The battery module to be assembled can be composed of at least two single cells. The single cells can have regular shapes such as square or circular, and it should be noted that the single cells can also have irregular shapes. The single cells can be lithium ion cells, for example, the single cells can be lithium iron phosphate cells, ternary cells or manganese iron lithium cells. It should be noted that for different types or models of battery modules, the connection mode of each single cell of the corresponding battery module is different. For example, each single cell can be connected in series and / or parallel.

[0029] CCS refers to a battery connection assembly, which is used to connect the integrated connection bus bars between the single cells. The CCS assembly design drawing data refers to the design drawing data of the corresponding battery connection assembly. For example, the CCS assembly design drawing data can include the size and shape of the corresponding battery connection assembly. For another example, the CCS assembly design drawing data can also be graphical data established based on a two-dimensional coordinate or a three-dimensional coordinate system.

[0030] According to the test battery module and the test battery connection assembly, the test CCS assembly design drawing data corresponding to the test battery connection assembly and the identity characteristic information corresponding to the test battery module are obtained, and then the image database of the identity characteristic information and the test CCS assembly design drawing data is established. When the battery connection assembly positioning and assembly of the battery module to be installed is needed, the identity characteristic information of the battery module to be installed is obtained, and the CCS assembly design drawing data corresponding to the battery module to be installed is obtained according to the identity characteristic information of the battery module to be installed by querying the pre-established image database. It should be noted that the identity characteristic information can be the model information of the battery module to be installed.

[0031] In step S220, the CCS projection pattern is generated according to the CCS assembly design drawing data, and the CCS projection pattern is projected on the first table surface.

[0032] The CCS projection pattern can be obtained by a light source. For example, the CCS projection pattern can be obtained by a mercury lamp, an LED light or a laser light. The first table surface can be a table surface of a workbench, and the workbench is used to support the connection assembly to be positioned.

[0033] For example, the CCS projection pattern has the same size as the corresponding battery connection assembly, that is, the CCS projection pattern is projected on the first table surface by 1:1 equal proportion, so as to position the connection assembly to be positioned.

[0034] In step S230, the connection assembly to be positioned is positioned and placed on the first table surface according to the CCS projection pattern.

[0035] The connection assembly to be positioned refers to the CCS assembly to be positioned.

[0036] For example, according to the CCS projection pattern projected on the first table surface, the connection assembly to be positioned is moved to the CCS projection pattern, so that the boundary line of the connection assembly to be positioned can coincide with the boundary line of the CCS projection pattern, and then the connection assembly to be positioned is placed on the first table surface, and the connection assembly to be positioned is accurately and conveniently positioned, so as to facilitate the assembly of the connection assembly to be positioned after positioning on the battery module to be installed.

[0037] In the above embodiment, the CCS component design drawing data corresponding to the battery module to be assembled is acquired; the CCS projection pattern is generated according to the CCS component design drawing data, and the CCS projection pattern is projected on the first table; and the connecting component to be positioned is positioned and placed on the first table according to the CCS projection pattern, so as to realize the positioning and assembly of the connecting component to be positioned. According to the CCS component design drawing data, the CCS projection pattern generated is projected on the first table, and then the connecting component to be positioned is positioned and placed according to the CCS projection pattern. The positioning of the battery connecting component suitable for different battery modules is realized by adjusting the projection pattern, without the need to use a special type of positioning tool, and the positioning of the battery connecting component suitable for different battery modules is realized, the number of positioning tools is reduced, the cost is reduced, the assembly efficiency of the battery connecting component is improved, and the universality of the positioning of the battery connecting component is improved.

[0038] In one embodiment, as shown in FIG. 3, a battery connecting component positioning method is provided. Taking the processor 102 in FIG. 1 as an example, the method includes the following steps:

[0039] In step S310, CCS component design drawing data corresponding to a battery module to be assembled is acquired.

[0040] In the above step S310, the specific description is referred to the description of the above embodiment, which is not repeated here.

[0041] In step S320, according to the CCS component design drawing data, an insulating sheet projection pattern and a conductive row projection pattern are generated, the insulating sheet projection pattern is projected on the first table, and the conductive row projection pattern is projected in the insulating sheet projection pattern.

[0042] The connecting component to be positioned can include an insulating sheet and a conductive row, the conductive row is arranged on the insulating sheet, and the conductive row is used to connect two adjacent single battery cells. The size of the insulating sheet projection pattern is the same as that of the insulating sheet of the corresponding connecting component to be positioned, for example, the insulating sheet projection pattern can be projected on the first table by 1:1 equal proportion, so as to position the insulating sheet of the corresponding connecting component to be positioned.

[0043] It should be noted that the size and shape of different types of insulating sheets are different, for example, the insulating sheet can be a regular shape such as a rectangle, a circle or an ellipse; for example, the insulating sheet can also be an irregular shape. Correspondingly, the insulating sheet projection pattern can be a regular shape such as a rectangle, a circle or an ellipse; the insulating sheet projection pattern can also be an irregular shape.

[0044] The conductive bar projection pattern has the same size as the conductive bar of the corresponding connection assembly to be positioned, for example, the conductive bar projection pattern can be projected on the first platform by 1:1 equal scale projection, so as to position the insulating sheet of the corresponding connection assembly to be positioned. It should be noted that the number of conductive bars is determined according to the number of single battery cells of the corresponding battery module to be assembled. That is, the number of conductive bar projection patterns is determined according to the number of single battery cells of the corresponding battery module to be assembled. For example, the battery module to be assembled includes two single battery cells, and the battery connection assembly can include two conductive bars, one of which is connected to the positive pole of each single battery cell, and the other of which is connected to the negative pole of each single battery cell, thereby realizing electrical connection of each single battery cell.

[0045] For example, according to the CCS assembly design drawing data, the insulating sheet projection pattern and the conductive bar projection pattern can be generated, and the insulating sheet projection pattern can be projected on the first platform by laser projection, and then the corresponding insulating sheet can be placed on the first platform, and the insulating sheet can be moved to the insulating sheet projection pattern, so that the boundary line of the insulating sheet coincides with the boundary line of the insulating sheet projection pattern, thereby realizing accurate positioning of the insulating sheet. Optionally, the conductive bar projection pattern can be projected in the insulating sheet projection pattern by laser projection, that is, the conductive bar projection pattern is projected on the insulating sheet, and then the corresponding conductive bar can be placed on the insulating sheet, and the conductive bar can be moved to the corresponding conductive bar projection pattern, so that the boundary line of the conductive bar coincides with the boundary line of the corresponding conductive bar projection pattern, thereby realizing accurate positioning of the conductive bar on the corresponding insulating sheet, thereby realizing accurate positioning of the connection assembly to be positioned.

[0046] In one example, whether the insulating sheet falls in the insulating sheet projection pattern can be monitored, when it is detected that the boundary line of the insulating sheet coincides with the boundary line of the insulating sheet projection pattern, a prompt signal corresponding to successful positioning of the insulating sheet can be generated, and the positioning situation can be reminded by voice and / or light, so that the user can know the positioning situation in real time. Similarly, whether the conductive bar falls in the conductive bar projection pattern can be monitored, when it is detected that the boundary line of the conductive bar coincides with the boundary line of the conductive bar projection pattern, a prompt signal corresponding to successful positioning of the conductive bar can be generated, and the positioning situation can be reminded by voice and / or light, so that the user can know the positioning situation in real time, thereby improving the positioning efficiency and positioning accuracy of the battery connection assembly.

[0047] In step S330, the connection assembly to be positioned is positioned and placed on the first platform according to the CCS projection pattern.

[0048] In the above step S330, the specific description is referred to the description of the above embodiment, which will not be repeated here.

[0049] In the above embodiment, by acquiring corresponding CCS component design drawing data, different CCS component design drawing data corresponds to the to-be-positioned connecting component of different battery models, according to the CCS component design drawing data, the generated insulating sheet projection pattern is projected on the first table, and the generated conductive row projection pattern is projected in the insulating sheet projection pattern, and then the insulating sheet projection pattern is used to position and place the insulating sheet of the to-be-positioned connecting component, and the conductive row projection pattern is used to position and place the corresponding conductive row, the positioning of the battery connecting component suitable for different battery modules is realized by adjusting the projection pattern, without using special type positioning tooling, the positioning of the battery connecting component suitable for different battery modules is realized, the number of positioning tooling is reduced, the cost is reduced, the assembly efficiency of the battery connecting component is improved, and the universality of the positioning of the battery connecting component is improved.

[0050] In one embodiment, the insulating sheet projection pattern comprises a first frame pattern and at least 2 connection hole group patterns; each connection hole group pattern is located in the first frame pattern.

[0051] In one embodiment, the connection hole group comprises 2 connection holes, and the connection holes can be used to facilitate the electrical connection of the pole of the single battery cell to the corresponding conductive row. The shape of the connection hole can be but is not limited to a circle or a square. Correspondingly, the connection hole group pattern can comprise 2 connection hole patterns. Each connection hole group is spaced apart, and each connection hole in the same connection hole group is spaced apart. It should be noted that the specific shape and size of the connection hole group pattern are determined according to the shape and size of each single battery cell of the to-be-assembled battery module.

[0052] The first frame pattern refers to the boundary line pattern of the insulating sheet. For example, if the insulating sheet is square-shaped, the corresponding first frame pattern is square-shaped. It should be noted that the first frame pattern can be composed of solid lines formed by the projection light source; the first frame pattern can also be composed of dashed lines formed by the projection light source, for example, the dashed lines can be composed of a plurality of dot shapes or a plurality of cross shapes.

[0053] For example, according to the CCS component design drawing data, the first frame pattern can be generated, and the first frame pattern can be projected on the first table by laser projection, and then the initial insulating sheet can be placed on the first table, and the initial insulating sheet can be moved to the first frame pattern, so that the boundary line of the initial insulating sheet coincides with the boundary line of the first frame pattern, and the accurate positioning of the initial insulating sheet is realized. It should be noted that a plurality of connection hole groups are pre-set on the insulating sheet according to the position of the conductive row, and the connection holes contained in the connection hole group play a role of giving way, so that the conductive row can directly contact the cell pole below the insulating sheet, and the subsequent process of welding is facilitated. The role of the insulating sheet is to isolate the contact between the cell and the module, and the entire cell upper surface is not directly contacted with the module wire harness, sensor, etc. except that the pole and the conductive row are directly contacted, so as to achieve the insulation effect.

[0054] In one embodiment, the conductive strip projection pattern comprises at least 2 positioning frame patterns; the step of projecting the conductive strip projection pattern within the insulating sheet projection pattern comprises:

[0055] According to the CCS component design drawing data, the positioning frame pattern is projected on the periphery of the corresponding connection hole group pattern.

[0056] The positioning frame pattern is used for positioning the conductive strip, and the positioning frame pattern can be in the shape of a square or a circle, etc. It should be noted that the size and shape of the positioning frame pattern can be determined according to the size and shape of the conductive strip.

[0057] The positioning frame pattern can be composed of solid outline lines formed by a projection light source; the positioning frame pattern can also be composed of dashed outline lines formed by a projection light source, for example, the dashed outline lines can be composed of a plurality of dot shapes or a plurality of cross shapes. It should be noted that the positioning frame pattern can also use other shapes of outline lines, which are suitable for clearly displaying the position of the conductive strip.

[0058] For example, according to the CCS component design drawing data, the positioning frame pattern is generated, and the positioning frame pattern is projected on the periphery of the corresponding connection hole group pattern by a laser projection method, i.e. the positioning frame pattern is projected on the periphery of the corresponding connection hole group of the insulating sheet, and then the corresponding conductive strip can be placed on the insulating sheet, and the insulating sheet is moved to the positioning frame pattern, so that the boundary line of the conductive strip coincides with the boundary line of the corresponding positioning frame pattern, and then the precise positioning of the conductive strip is realized, thereby facilitating the electrical connection of the conductive strip to the pole of the single battery cell through the corresponding connection hole group, realizing the positioning assembly of the battery connection assembly, without using a special type of positioning tool, which can be suitable for the positioning of the battery connection assembly of different battery modules, reducing the number of positioning tools, reducing the cost, improving the assembly efficiency of the battery connection assembly, and improving the versatility of the positioning of the battery connection assembly.

[0059] In one embodiment, as shown in FIG. 4, the connection assembly to be positioned comprises an insulating sheet to be positioned and at least 2 conductive strips; the step of positioning and placing the connection assembly to be positioned on the first table according to the CCS projection pattern comprises:

[0060] In step S410, the insulating sheet to be positioned is placed on the first table, the insulating sheet to be positioned is positioned according to the first frame pattern, and each positioning frame pattern is formed on the positioned insulating sheet.

[0061] The to-be-positioned insulation sheet can be a PC (polycarbonate) insulation sheet. It should be noted that the to-be-positioned insulation sheet can also be made of other insulation materials; for example, the to-be-positioned insulation sheet can also be a PP (polypropylene) insulation sheet. The conductive bar is also called a bus bar or a connecting piece, and the conductive bar can be a connecting piece made of aluminum, copper, or a mixture of at least two conductive metals.

[0062] For example, the to-be-positioned insulation sheet can be provided with a set of connecting holes in advance. A first frame pattern can be generated according to CCS component design drawing data, and the first frame pattern can be projected on the first table by laser projection. Then, the corresponding to-be-positioned insulation sheet can be placed on the first table, and the to-be-positioned insulation sheet can be moved to the first frame pattern, so that the boundary line of the to-be-positioned insulation sheet coincides with the boundary line of the first frame pattern, thereby achieving accurate positioning of the to-be-positioned insulation sheet and obtaining a positioned insulation sheet. Alternatively, a positioning frame pattern can be generated according to the CCS component design drawing data, and the positioning frame pattern can be projected on the periphery of the set of connecting holes of the to-be-positioned insulation sheet by laser projection, thereby forming each positioning frame pattern on the positioned insulation sheet.

[0063] In step S420, each conductive bar is placed on the positioned insulation sheet, and each conductive bar is positioned according to each positioning frame pattern.

[0064] By placing the corresponding conductive bar on the insulation sheet and moving the insulation sheet to the positioning frame pattern, the boundary line of the conductive bar coincides with the boundary line of the corresponding positioning frame pattern, thereby achieving accurate positioning of the conductive bar. This facilitates electrically connecting the conductive bar to the pole of the single battery cell through the corresponding set of connecting holes, realizes positioning and assembly of the battery connecting assembly, eliminates the need for a special type of positioning tool, and is suitable for positioning of battery connecting assemblies of different battery modules. This reduces the number of positioning tools, reduces costs, improves the assembly efficiency of the battery connecting assembly, and improves the versatility of positioning of the battery connecting assembly.

[0065] In one embodiment, as shown in FIG. 5, the to-be-positioned connecting assembly is provided with a positioning hole; the step of positioning and placing the to-be-positioned connecting assembly on the first table according to the CCS projection pattern includes:

[0066] In step S510, the to-be-positioned connecting assembly is placed on the first table, and a positioning point pattern is output to the first table.

[0067] The positioning hole can be, but is not limited to, a circular or rectangular shape; the positioning hole can be a through hole or a non-through hole. The positioning hole can be arranged at the center of the insulation sheet; the positioning hole can be used to project a light source to quickly and accurately position the insulation sheet. The positioning point pattern can be, but is not limited to, a laser point pattern.

[0068] For example, the user can place the to-be-positioned connection assembly on the first table by manual operation, and control the projection light source to output the positioning point pattern to the first table, and then the user can quickly position the to-be-positioned connection assembly according to the positioning point pattern. For another example, the to-be-positioned connection assembly can be placed on the first table by a transmission mechanism in an automatic operation mode, and the projection light source is controlled to output the positioning point pattern to the first table, and then the transmission mechanism can quickly drive the to-be-positioned connection assembly to move according to the positioning point pattern to position the to-be-positioned connection assembly.

[0069] In step S520, the position of the to-be-positioned connection assembly is adjusted according to the positioning point pattern until the positioning point pattern falls into the positioning hole.

[0070] For example, the to-be-positioned connection assembly is driven to approach the positioning point pattern according to the positioning point pattern until the positioning hole of the to-be-positioned connection assembly coincides with the positioning point pattern, that is, when the positioning point pattern falls into the positioning hole, it is determined that the preliminary position positioning of the to-be-positioned connection assembly is completed.

[0071] In step S530, the angle of the to-be-positioned connection assembly is adjusted according to the CCS projection pattern until the to-be-positioned connection assembly coincides with the CCS projection pattern.

[0072] For example, the CCS projection pattern is generated according to the CCS component design drawing data, and the CCS projection pattern is projected on the first table by laser projection, and then the to-be-positioned connection assembly can be rotated based on the center of the positioning hole for quick angle adjustment of the to-be-positioned connection assembly, so that the boundary line of the to-be-positioned connection assembly coincides with the boundary line of the CCS projection pattern, and then the to-be-positioned connection assembly is quickly and accurately positioned, thereby facilitating the electrical connection of the to-be-positioned connection assembly to the pole of the single battery cell, realizing the positioning and assembly of the battery connection assembly, without the need for a special type of positioning tool, which can be applied to the positioning of battery connection assemblies of different battery modules, reducing the number of positioning tools, reducing costs, improving the assembly efficiency of the battery connection assembly, and improving the universality of the positioning of the battery connection assembly.

[0073] In one embodiment, as shown in FIG. 6, a battery connection assembly positioning method is provided, which is applied to the processor 102 in FIG. 1 as an example for illustration, including the following steps:

[0074] In step S610, the CCS number corresponding to the to-be-assembled battery module is obtained.

[0075] The CCS number can be the material number or model number of the battery connection assembly. For example, battery modules of the same model have the same CCS number, and battery modules of different models have different CCS numbers.

[0076] Step S620, according to the CCS number, query the preset CCS image library to get the CCS component design drawing data.

[0077] The preset CCS image library can be obtained according to historical test data, for example, the test CCS component design drawing data corresponding to the test battery module and the CCS number corresponding to the test battery module can be obtained according to the test battery module, and then the preset CCS image library of the CCS number and the test CCS component design drawing data is established.

[0078] When the battery connection assembly needs to be positioned and assembled for the to-be-assembled battery module, the CCS number of the to-be-assembled battery module can be obtained, and the CCS component design drawing data corresponding to the to-be-assembled battery module can be obtained by querying the preset CCS image library according to the CCS number of the to-be-assembled battery module.

[0079] Step S630, according to the CCS component design drawing data, generate the CCS projection pattern, and project the CCS projection pattern on the first table.

[0080] The specific description of step S630 is described above, and will not be repeated here.

[0081] Step S640, according to the CCS projection pattern, position and place the to-be-positioned connection assembly on the first table.

[0082] The specific description of step S640 is described above, and will not be repeated here.

[0083] In the above embodiment, according to the CCS number, the corresponding CCS component design drawing data is obtained by querying the preset CCS image library. Different CCS component design drawing data corresponds to the to-be-positioned connection assembly of different battery models. According to the CCS component design drawing data, the generated CCS projection pattern is projected on the first table, and then the to-be-positioned connection assembly is positioned and placed according to the CCS projection pattern. By adjusting the projection pattern, the positioning of the battery connection assembly suitable for different battery modules is realized. Without using special type positioning tooling, the positioning of the battery connection assembly suitable for different battery modules is realized, the number of positioning tooling is reduced, the cost is reduced, the assembly efficiency of the battery connection assembly is improved, and the universality of the positioning of the battery connection assembly is improved. In addition, it can be applied to temporary sample making demand. Only by importing the projection pattern of the sample making CCS according to the design drawing, the corresponding battery connection assembly sample can be quickly obtained, the new product trial preparation period is shortened, and the product development efficiency is improved.

[0084] In one embodiment, the battery connection assembly positioning method further comprises the steps of: when the CCS assembly design drawing data is changed, obtaining target CCS assembly design drawing data; and updating the corresponding CCS assembly design drawing data in the preset CCS image library according to the target CCS assembly design drawing data.

[0085] The target CCS assembly design drawing data refers to the CCS assembly design drawing data after the drawing change.

[0086] When the CCS assembly design drawing data is changed, the target CCS assembly design drawing data can be obtained, and the corresponding CCS assembly design drawing data in the preset CCS image library can be updated according to the target CCS assembly design drawing data, so that the corresponding projection pattern can be quickly changed when the CCS design drawing is changed, and the modification or new manufacturing process of the conventional tooling can be avoided, so that the next positioning of the connection assembly to be positioned can be matched to the corresponding CCS assembly design drawing data, and the positioning of the battery connection assembly suitable for different battery modules is realized, and the assembly efficiency and positioning universality of the battery connection assembly are improved.

[0087] It should be understood that although each step in the flowcharts of FIGS. 2 to 6 is displayed in sequence according to the direction of the arrow, these steps are not necessarily executed in sequence according to the direction of the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, at least part of the steps in FIGS. 2 to 6 can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these sub-steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least part of other steps or sub-steps or stages of other steps.

Each module described above can be embedded in the processor of the battery connection assembly positioning system in hardware form or independent of the processor, or stored in the memory of the battery connection assembly positioning system in software form, so that the processor invokes and executes the corresponding operations of each module described above.

[0094] The projection control module 710 can be used to control the projection light source to output a corresponding CCS projection pattern. For example, the projection control module 710 can include a processor and a projection light source, and the processor is connected to the projection light source, which can be but is not limited to a laser projection light source. The workbench has a first table top, which can be used to support the connection assembly to be positioned, and the CCS projection pattern output by the projection light source can be projected on the first table top of the workbench.
