[0048] In addition, the term "plurality" shall mean two or more.

[0049] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0050] The battery connection assembly positioning method provided in this application can be applied to Figure 1 In the application environment shown. Among them, the processing device may include a processor 102 and a memory 104, and the memory 104 may be used to store CCS component design drawing data and CCS projection pattern and other data. The processor 102 may be used to obtain the CCS component design drawing data corresponding to the battery module to be installed; according to the CCS component design drawing data, a CCS projection pattern is generated, and the CCS projection pattern is projected on the first table; according to the CCS projection pattern, the connection component to be positioned is positioned and placed on the first table. The processing device may also include a display 106, and the display 106 may display CCS component design drawing data and CCS projection pattern and other data through a graphical interface. Exemplarily, the processing device may be a projection control device.

[0051] In one embodiment, Figure 2 As shown, a battery connection assembly positioning method is provided, and the method is applied to Figure 1 The processor 102 in the embodiment is taken as an example to illustrate, and the following steps are included:

[0052] Step S210, obtaining CCS component design drawing data corresponding to the battery module to be installed.

[0053] Among them, the battery module to be installed may be composed of at least 2 single cells. The single cell may be a regular shape structure such as a square or a circle. It should be noted that the single cell may also be an irregular shape structure. The single cell may be a lithium ion cell. For example, the single cell may be a lithium iron phosphate cell, a ternary cell or a manganese iron lithium cell. It should be noted that for different types or models of battery modules, the connection method of each single cell of the corresponding battery module is different. For example, each single cell can be connected in series and / or in parallel.

[0054] CCS refers to a battery connection assembly, which is used to connect the integrated connection busbars between single cells; CCS assembly design drawing data refers to the design drawing data of the corresponding battery connection assembly. For example, CCS assembly design drawing data may include data such as the size and shape of the corresponding battery connection assembly. For another example, CCS assembly design drawing data may also be graphic data established based on a two-dimensional coordinate system or a three-dimensional coordinate system.

[0055] Exemplarily, based on the test battery module and the test battery connection assembly, the test CCS component design drawing data of the corresponding test battery connection assembly and the identity feature information of the corresponding test battery module can be obtained, and then an image database of the identity feature information and the test CCS component design drawing data can be established. When it is necessary to position and assemble the battery connection assembly of the battery module to be installed, the identity feature information of the battery module to be installed can be obtained, and based on the identity feature information of the battery module to be installed, a pre-established image database can be queried to obtain the CCS component design drawing data of the corresponding battery module to be installed. It should be noted that the identity feature information can be the model information of the battery module to be installed.

[0056] Step S220, generating a CCS projection pattern according to the CCS component design drawing data, and projecting the CCS projection pattern onto the first table surface.

[0057] The CCS projection pattern can be obtained by projection of a light source. For example, the CCS projection pattern can be obtained by projection of a light source such as a mercury lamp, LED light or laser. The first table surface can be a table surface of a workbench, and the workbench is used to support the connection component to be positioned.

[0058] For example, the CCS projection pattern is the same size as the corresponding battery connection component, that is, the CCS projection pattern is projected on the first table surface in a 1:1 ratio to facilitate the positioning of the connection component to be positioned.

[0059] Step S230: Position the connection component to be positioned and place it on the first table according to the CCS projection pattern.

[0060] The connection component to be positioned refers to the battery connection component to be positioned (ie, the CCS component to be positioned).

[0061] For example, according to the CCS projection pattern projected on the first table, the connection component to be positioned is moved to the CCS projection pattern so that the boundary line of the connection component to be positioned can coincide with the boundary line of the CCS projection pattern, thereby placing the connection component to be positioned on the first table, and accurately and conveniently positioning the connection component to be positioned, thereby facilitating the assembly of the connection component to be positioned on the battery module to be installed after the positioning is completed.

[0062] In the above-mentioned embodiment, by obtaining the CCS component design drawing data corresponding to the battery module to be installed; generating a CCS projection pattern according to the CCS component design drawing data, and projecting the CCS projection pattern on the first table surface; according to the CCS projection pattern, the connection component to be positioned is positioned and placed on the first table surface, so as to realize the positioning and assembly of the connection component to be positioned. The present application obtains the corresponding CCS component design drawing data, and different CCS component design drawing data correspond to the connection components to be positioned of different battery models. According to the CCS component design drawing data, the generated CCS projection pattern is projected on the first table surface, and then the connection component to be positioned is positioned and placed according to the CCS projection pattern. The positioning of the battery connection components suitable for different battery modules is realized by adjusting the projection pattern. There is no need to use a special type of positioning tooling, and the positioning of the battery connection components suitable for different battery modules can be realized, which reduces the number of positioning tooling, reduces the cost, improves the assembly efficiency of the battery connection components, and improves the versatility of the positioning of the battery connection components.

[0063] In one embodiment, Figure 3 As shown, a battery connection assembly positioning method is provided, and the method is applied to Figure 1 The processor 102 in the embodiment is taken as an example to illustrate, and the following steps are included:

[0064] Step S310, obtaining CCS component design drawing data corresponding to the battery module to be installed.

[0065] For the specific description of the above step S310, please refer to the description of the above embodiment, which will not be repeated here.

[0066] Step S320, generating an insulating sheet projection pattern and a conductive row projection pattern according to the CCS component design drawing data, projecting the insulating sheet projection pattern onto the first table, and projecting the conductive row projection pattern into the insulating sheet projection pattern.

[0067] The connection component to be positioned may include an insulating sheet and a conductive bar, the conductive bar is arranged on the insulating sheet, and the conductive bar is used to connect two adjacent single cells. The projection pattern of the insulating sheet is the same size as the insulating sheet of the corresponding connection component to be positioned, for example, the projection pattern of the insulating sheet can be projected on the first table in a 1:1 ratio so as to position the insulating sheet of the corresponding connection component to be positioned.

[0068] It should be noted that the sizes and shapes 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; or an irregular shape. Correspondingly, the insulating sheet projection pattern can be a regular shape such as a rectangle, a circle or an ellipse; or an irregular shape.

[0069] The projection pattern of the conductive row is the same size as the conductive row of the corresponding connection component to be positioned. For example, the projection pattern of the conductive row can be projected on the first table surface at a 1:1 ratio so as to position the insulating sheet of the corresponding connection component to be positioned. It should be noted that the number of conductive rows is determined according to the number of single cells of the corresponding battery module to be installed. That is, the number of conductive row projection patterns is determined according to the number of single cells of the corresponding battery module to be installed. For example, the battery module to be installed includes 2 single cells, and the battery connection component may include 2 conductive rows, one of which is connected to the positive poles of the two single cells, and the other conductive row is connected to the negative poles of the two single cells, thereby realizing the electrical connection of each single cell.

[0070] Exemplarily, the insulating sheet projection pattern and the conductive row projection pattern can be generated according to the CCS component design drawing data, and the insulating sheet projection pattern can be projected onto the first table surface by laser projection, and then the corresponding insulating sheet can be placed on the first table surface, 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 achieving accurate positioning of the insulating sheet. Further, the conductive row projection pattern can be projected into the insulating sheet projection pattern by laser projection, that is, the conductive row projection pattern is projected onto the insulating sheet, and then the corresponding conductive row can be placed on the insulating sheet, and the conductive row can be moved to the corresponding conductive row projection pattern so that the boundary line of the conductive row coincides with the boundary line of the corresponding conductive row projection pattern, thereby achieving accurate positioning of the conductive row on the corresponding insulating sheet, thereby achieving accurate positioning of the connection component to be positioned.

[0071] In one example, it is possible to monitor whether the insulating sheet falls on the projection pattern of the insulating sheet. When it is detected that the boundary line of the insulating sheet coincides with the boundary line of the projection pattern of the insulating sheet, a prompt signal corresponding to the successful positioning of the insulating sheet can be generated, and a reminder can be given through voice and / or light, so that the user can understand the positioning situation in real time. Similarly, it is possible to monitor whether the conductive bar falls on the projection pattern of the conductive bar. When it is detected that the boundary line of the conductive bar coincides with the boundary line of the projection pattern of the conductive bar, a prompt signal corresponding to the successful positioning of the conductive bar can be generated, and a reminder can be given through voice and / or light, so that the user can understand the positioning situation in real time, thereby improving the positioning efficiency and positioning accuracy of the battery connection assembly.

[0072] Step S330: Position the connection component to be positioned and place it on the first table according to the CCS projection pattern.

[0073] For the specific description of the above step S330, please refer to the description of the above embodiment, which will not be repeated here.

[0074] In the above-mentioned embodiment, by obtaining corresponding CCS component design drawing data, different CCS component design drawing data correspond to the connection components to be positioned of different battery models, and according to the CCS component design drawing data, the generated insulating sheet projection pattern is projected onto the first table surface, and the generated conductive bar projection pattern is projected into the insulating sheet projection pattern, and then the insulating sheet of the connection component to be positioned is positioned and placed according to the insulating sheet projection pattern, and the corresponding conductive bar is positioned and placed according to the conductive bar projection pattern, and the positioning of the battery connection components suitable for different battery modules is achieved by adjusting the projection pattern, without the need to use special types of positioning tooling, and the positioning of the battery connection components suitable for different battery modules can be achieved, thereby reducing the number of positioning tooling, reducing costs, improving the assembly efficiency of the battery connection components, and improving the versatility of the positioning of the battery connection components.

[0075] In one embodiment, the insulating sheet projection pattern includes a first frame pattern and at least two connection hole group patterns; each connection hole group pattern is located within the first frame pattern.

[0076] Among them, the connection hole group may include two connection holes, and the connection holes can be used to facilitate the electrical connection of the pole of the single cell to the corresponding conductive bar. The shape of the connection hole can be but is not limited to circular or square. Accordingly, the connection hole group pattern may include two connection hole patterns. Each connection hole group is arranged at intervals and each connection hole of the same connection hole group is arranged at intervals. 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 cell of the battery module to be installed.

[0077] The first frame pattern refers to the boundary line pattern of the insulating sheet. For example, if the insulating sheet is in a square shape, the corresponding first frame pattern is in a square shape. 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 dotted lines formed by the projection light source, for example, the dotted lines can be composed of a plurality of dot shapes or a plurality of cross shapes.

[0078] For example, a first frame pattern can be generated according to the CCS component design drawing data, and the first frame pattern can be projected onto the first table surface by laser projection, and then the corresponding initial insulating sheet can be placed on the first table surface, 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, thereby achieving accurate positioning of the initial insulating sheet. It should be noted that a plurality of connection hole groups are preset on the insulating sheet according to the position of the conductive row, and the connection holes included in the connection hole group play a role of giving way, so that the conductive row can directly contact the battery cell pole under the insulating sheet, which is convenient for subsequent welding of the two. The function of the insulating sheet is to isolate the contact between the battery cell and the module. Except for the direct contact between the pole and the conductive row on the entire upper surface of the battery cell, other positions on the top of the battery cell are not in direct contact with the wiring harness, sensor, etc. of the module, thereby achieving an insulation effect.

[0079] In one embodiment, the conductive row projection pattern includes at least two positioning frame patterns; and the step of projecting the conductive row projection pattern into the insulating sheet projection pattern includes:

[0080] According to the CCS component design drawing data, the positioning frame pattern is projected onto the periphery of the corresponding connection hole group pattern.

[0081] The positioning frame pattern is used to position the conductive bar, and the positioning frame pattern may be in a shape other than square or circular. It should be noted that the size and shape of the positioning frame pattern may be determined according to the size and shape of the conductive bar.

[0082] The positioning frame pattern may be composed of solid contour lines formed by the projection light source; the positioning frame pattern may also be composed of dotted contour lines formed by the projection light source, for example, the dotted contour lines may be composed of a plurality of dot-shaped shapes or a plurality of cross-shaped shapes. It should be noted that the positioning frame pattern may also use contour lines of other shapes, so as to clearly show the position of the conductive bar.

[0083] For example, a positioning frame pattern is generated according to the CCS component design drawing data, and the positioning frame pattern is projected onto the periphery of the corresponding connection hole group pattern by laser projection, that is, the positioning frame pattern is projected onto the periphery of the corresponding connection hole group of the insulating sheet, and then the corresponding conductive bar 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 bar coincides with the boundary line of the corresponding positioning frame pattern, thereby achieving precise positioning of the conductive bar, thereby facilitating the electrical connection of the conductive bar to the pole of the single cell through the corresponding connection hole group, and realizing the positioning and assembly of the battery connection assembly. There is no need to use a special type of positioning tooling, and it can be suitable for the positioning of battery connection assemblies of different battery modules, thereby reducing the number of positioning tooling, reducing costs, improving the assembly efficiency of the battery connection assembly, and improving the versatility of the positioning of the battery connection assembly.

[0084] In one embodiment, Figure 4 As shown, the connection component to be positioned includes an insulating sheet to be positioned and at least two conductive bars; according to the CCS projection pattern, the steps of positioning and placing the connection component to be positioned on the first table include:

[0085] Step S410 , placing the insulating sheet to be positioned on the first table, positioning the insulating sheet to be positioned according to the first frame pattern, and forming various positioning frame patterns on the positioned insulating sheet.

[0086] The insulating sheet to be positioned may be a PC (polycarbonate) insulating sheet. It should be noted that the insulating sheet to be positioned may also be made of other insulating materials; for example, the insulating sheet to be positioned may also be a PP (polypropylene) insulating sheet. The conductive bar is also called a bus bar or a connector, and the conductive bar may be a connector made of aluminum, copper, or a mixed material composed of at least two conductive metals.

[0087] For example, the insulating sheet to be positioned may be pre-set with a connection hole group, and a first frame pattern may be generated according to the CCS component design drawing data, and the first frame pattern may be projected onto the first table surface by laser projection, and then the corresponding insulating sheet to be positioned may be placed on the first table surface, and the insulating sheet to be positioned may be moved to the first frame pattern, so that the boundary line of the insulating sheet to be positioned coincides with the boundary line of the first frame pattern, thereby achieving accurate positioning of the insulating sheet to be positioned and obtaining the positioned insulating sheet. Furthermore, a positioning frame pattern may be generated according to the CCS component design drawing data, and the positioning frame pattern may be projected onto the periphery of the connection hole group of the insulating sheet to be positioned by laser projection, thereby forming each positioning frame pattern on the positioned insulating sheet.

[0088] Step S420, placing each conductive bar on the positioned insulating sheet, and positioning each conductive bar according to each positioning frame pattern.

[0089] By placing the corresponding conductive bus on the insulating sheet and moving the insulating sheet to the positioning frame pattern, the boundary line of the conductive bus coincides with the boundary line of the corresponding positioning frame pattern, thereby achieving precise positioning of the conductive bus, thereby facilitating electrical connection of the conductive bus to the pole of the single cell through the corresponding connection hole group, thereby achieving positioning and assembly of the battery connection assembly. There is no need to use special positioning tooling, and the positioning of battery connection assemblies of different battery modules can be applied, thereby reducing the number of positioning tooling, reducing costs, improving the assembly efficiency of the battery connection assembly, and improving the versatility of the positioning of the battery connection assembly.

[0090] In one embodiment, Figure 5 As shown, the connection component to be positioned is provided with a positioning hole; according to the CCS projection pattern, the step of positioning and placing the connection component to be positioned on the first table surface includes:

[0091] Step S510: placing the connection component to be positioned on a first table, and outputting a positioning point pattern to the first table.

[0092] The positioning hole may be, but is not limited to, circular or rectangular; the positioning hole may be a through hole or a non-through hole. The positioning hole may be set at the center of the insulating sheet; the positioning hole may be used to project a light source to quickly and accurately position the insulating sheet. The positioning point pattern may be, but is not limited to, a laser point pattern.

[0093] For example, the user can manually place the connection component to be positioned on the first table, and control the projection light source to output a positioning point pattern to the first table, and then the user can quickly position the connection component to be positioned according to the positioning point pattern. For another example, the connection component to be positioned can be placed on the first table automatically through the transmission mechanism, and the projection light source can be controlled to output a positioning point pattern to the first table, and then the transmission mechanism can quickly drive the connection component to be positioned to move according to the positioning point pattern to position the connection component to be positioned.

[0094] Step S520: adjusting the position of the connection component to be positioned according to the positioning point pattern until the positioning point pattern falls into the positioning hole.

[0095] For example, according to the positioning point pattern, the connection component to be positioned is driven to approach the positioning point pattern until the positioning hole of the connection component to be positioned coincides with the positioning point pattern, that is, when the positioning point pattern falls into the positioning hole, it is determined that the initial position positioning of the connection component to be positioned is completed.

[0096] Step S530, adjusting the angle of the connection component to be positioned according to the CCS projection pattern until the connection component to be positioned coincides with the CCS projection pattern.

[0097] For example, a CCS projection pattern is generated according to CCS component design drawing data, and the CCS projection pattern is projected onto the first table surface by laser projection, and then the connection component to be positioned can be rotated based on the positioning hole as the center, so as to quickly adjust the angle of the connection component to be positioned, so that the boundary line of the connection component to be positioned coincides with the boundary line of the CCS projection pattern, thereby achieving rapid and accurate positioning of the connection component to be positioned, thereby facilitating the electrical connection of the connection component to be positioned to the pole of the single cell, and realizing the positioning and assembly of the battery connection component. There is no need to use special types of positioning tooling, and it can be suitable for the positioning of battery connection components of different battery modules, thereby reducing the number of positioning tooling, reducing costs, improving the assembly efficiency of battery connection components, and improving the versatility of positioning of battery connection components.

[0098] In one embodiment, Figure 6 As shown, a battery connection assembly positioning method is provided, and the method is applied to Figure 1 The processor 102 in the embodiment is taken as an example to illustrate, and the following steps are included:

[0099] Step S610, obtaining the CCS number of the battery module to be installed.

[0100] The CCS number may be a material number or model number of a battery connection component. For example, battery modules of the same model to be installed have the same CCS number, and battery modules of different models to be installed have different CCS numbers.

[0101] Step S620, according to the CCS number, query the preset CCS image library to obtain the CCS component design drawing data.

[0102] Among them, the preset CCS image library can be established based on historical test data. For example, based on the test battery module, the test CCS component design drawing data of the corresponding test battery module and the CCS number of the corresponding test battery module can be obtained, and then the preset CCS image library of the CCS number and the test CCS component design drawing data can be established.

[0103] When it is necessary to position and assemble the battery connection components of the battery module to be installed, the CCS number of the battery module to be installed can be obtained, and according to the CCS number of the battery module to be installed, the preset CCS image library can be queried to obtain the CCS component design drawing data corresponding to the battery module to be installed.

[0104] Step S630, generating a CCS projection pattern according to the CCS component design drawing data, and projecting the CCS projection pattern onto the first table surface.

[0105] For the specific description of the above step S630, please refer to the description of the above embodiment, which will not be repeated here.

[0106] Step S640: Position the connection component to be positioned and place it on the first table surface according to the CCS projection pattern.

[0107] For the specific description of the above step S640, please refer to the description of the above embodiment, which will not be repeated here.

[0108] In the above-mentioned embodiment, according to the CCS number, the preset CCS image library is queried to obtain the corresponding CCS component design drawing data. Different CCS component design drawing data correspond to the connection components to be positioned of different battery models. According to the CCS component design drawing data, the generated CCS projection pattern is projected onto the first table surface, and then the connection components to be positioned are positioned and placed according to the CCS projection pattern. The positioning of the battery connection components suitable for different battery modules is achieved by adjusting the projection pattern. There is no need to use special positioning tooling.

Further, a positioning frame pattern 730 may be generated according to the CCS component design drawing data, and the positioning frame pattern 730 may be projected on the periphery of the connection hole group 7222 of the insulating sheet 722 to be positioned by laser projection, thereby forming each positioning frame pattern 730 on the positioned insulating sheet 722.
