Description

Technical Field

[0001] The present invention relates to the technical field of battery cover plate processing, and in particular to a battery cover plate processing method and processing equipment. Background Art

[0002] In the production process of the battery cover, it is necessary to assemble the bushing on the battery cover so that the battery cover can be assembled with other panels to form a battery box or to facilitate the installation of the battery cover. Specifically, a mounting hole is first opened on the battery cover, and then the bushing is assembled into the mounting hole. In order to ensure that the battery cover can be accurately assembled or installed later, the existing technology will detect the size and position of the bushing assembled on the battery cover.

[0003] From the above, the prior art specifically adopts a detection method in which the bushing on each battery cover is detected after the bushing assembly operation is completed. Since the size and position of the bushing assembled on the battery cover are mainly affected by the size, position and shape of the mounting hole, after each unqualified battery cover is detected, it is necessary to adjust the working parameters of the processing device used to process the mounting hole on the battery cover to ensure that the size, position and shape of the mounting hole opened on the subsequent battery cover meet the requirements, thereby ensuring that the size and position of the bushing assembled on the subsequent battery cover meet the requirements. However, since it is necessary to open the mounting hole on the battery cover before assembling the bushing, for the detection method in which the bushing on the battery cover is detected after the bushing assembly operation is completed, when unqualified battery covers are detected, several battery covers have been opened with mounting holes that do not meet the requirements, resulting in batch scrapping of the battery covers. Summary of the invention

[0004] The object of the present invention is to provide a battery cover plate processing method and processing equipment to solve the problem that after the bushing assembly operation on the battery cover plate is completed, the bushing on the battery cover plate is inspected. When unqualified battery covers are detected, several battery covers have installation holes that do not meet the requirements, thereby causing the battery covers to be scrapped in batches.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0037] In the description of this embodiment, the terms "upper", "lower", "right", "left" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] Based on the above mentioned contents, Figure 3 As shown, combined with Figure 1 and Figure 2 This embodiment provides a battery cover processing method, the battery cover processing method comprising:

[0039] S1, processing the mounting hole 111 on the battery cover 110 by a processing device;

[0040] S2. After the mounting hole 111 is processed, the size parameters, position parameters and shape parameters of the mounting hole 111 on the battery cover plate 110 are detected;

[0041] S3. If the deviation value of the size and / or position and / or shape of the mounting hole 111 exceeds the preset range, the working parameters of the processing device are adjusted; if the deviation values ​​of the size, position and shape of the mounting hole 111 are all within the preset range, the bushing 120 is installed in the mounting hole 111.

[0042] From the above, this embodiment adopts a detection method of detecting the mounting hole 111 immediately after the mounting hole 111 is formed on the battery cover plate 110. When a battery cover plate 110 with an unqualified mounting hole 111 is detected, the processing parameters of the processing device are adjusted to ensure that the size, position and shape of the mounting hole 111 opened on the subsequent battery cover plate 110 meet the requirements. Moreover, in this embodiment, the mounting hole 111 on the battery cover plate 110 is detected immediately after the mounting hole 111 is opened, so as to avoid the upstream processing device from continuously opening unqualified mounting holes 111 on several battery cover plates 110, thereby preventing the problem of batch scrapping of battery cover plates 110.

[0043] It is understandable that this embodiment detects the size parameters, position parameters and shape parameters of the mounting hole 111, thereby being able to detect parameters such as the contour, aperture, position, and flatness of the mounting hole 111, thereby performing a comprehensive inspection of the mounting hole 111.

[0044] Moreover, it is worth noting that the preset range mentioned above is specifically set according to actual production requirements, and this embodiment does not make any specific limitation on this.

[0045] In addition, in the present embodiment, the mounting hole 111 on any battery cover plate 110 is inspected after the mounting hole 111 is processed, that is, the present embodiment adopts a full inspection method to inspect the battery cover plate 110 after the mounting hole 111 is processed, so that the processing parameters of the processing device can be corrected in time, thereby improving the production qualification rate of the battery cover plate 110.

[0046] Furthermore, the present embodiment also provides a battery cover processing equipment, which adopts the battery cover processing method as described above to assemble the bushing 120 on the battery cover 110. From the above, the battery cover processing equipment includes a processing device, a first detection device and a bushing assembly device, wherein the processing device is arranged at the processing station and is configured to process the mounting hole 111 on the battery cover 110, the first detection device is arranged at the first detection station and is configured to detect the size parameters, position parameters and shape parameters of the mounting hole 111, and the bushing assembly device is arranged at the assembly station and is configured to install the bushing 120 in the mounting hole 111.

[0047] As described above, in this embodiment, the battery cover 110 is first transferred to the processing station, and the processing device opens the mounting hole 111 on the battery cover 110. After that, the battery cover 110 with the mounting hole 111 is transferred from the processing station to the first detection station, and the first detection device detects the size parameters, position parameters and shape parameters of the mounting hole 111. If the deviation value of the size and / or position and / or shape of the mounting hole 111 exceeds the preset range, the staff adjusts the working parameters of the processing device. After the adjustment is completed, the processing device continues to open the mounting hole 111 on the subsequent battery cover 110. After that, the first detection device detects the subsequent The size parameters, position parameters and shape parameters of the mounting hole 111 on the battery cover 110 are continuously inspected. If the deviation value of the size and / or position and / or shape of the mounting hole 111 still exceeds the preset range, the staff continues to adjust the working parameters of the processing device until the first detection device detects that the deviation values ​​of the size, position and shape of the mounting hole 111 are all within the preset range. After that, the battery cover 110 is transferred from the first detection station to the assembly station, and the assembly device installs the bushing 120 in the mounting hole 111. After that, the battery cover 110 installed with the bushing 120 is removed from the assembly station and transferred to other downstream stations.

[0048] Since the mounting holes 111 on the battery cover plate 110 are inspected immediately after the mounting holes 111 are opened in this embodiment, it is possible to avoid the upstream processing device from continuously opening unqualified mounting holes 111 on several battery cover plates 110, thereby preventing the battery cover plates 110 from being scrapped in batches.

[0049] Based on the above, the first detection device can detect the mounting holes 111 on all battery cover plates 110 flowing out of the processing station, so that the processing parameters of the processing device can be corrected in time, thereby improving the production qualification rate of the battery cover plates 110.

[0050] That is, in this embodiment, if the deviation value of the size and / or position and / or shape of the mounting hole 111 exceeds the preset range, the staff adjusts the working parameters of the processing device. After the adjustment is completed, the processing device continues to open the mounting hole 111 on the next battery cover 110. Thereafter, the first detection device detects the size parameters, position parameters and shape parameters of the mounting hole 111 on the next battery cover 110. If the deviation value of the size and / or position and / or shape of the mounting hole 111 still exceeds the preset range, the staff continues to adjust the working parameters of the processing device until the first detection device detects that the deviation values ​​of the size, position and shape of the mounting hole 111 are all within the preset range.

[0051] Exemplarily, in this embodiment, the processing device is a laser cutting device. If the deviation value of the size and / or position and / or shape of the mounting hole 111 exceeds a preset range, the process parameters of the laser cutting device are adjusted. Specifically, the staff can correct the deviation of the size and / or position and / or shape of the mounting hole 111 by adjusting one or more of the process parameters of the laser cutting device, such as the laser power, cutting speed, gas flow and pressure, and feed speed.

[0052] It is worth noting that in this embodiment, the laser cutting device is a conventional laser punching machine. Since the specific structure and working principle of the laser cutting device are existing technologies, and its specific structure and working principle do not involve the improvements made by the present invention to the existing technologies, this embodiment will not elaborate on this.

[0053] It is also worth mentioning that in this embodiment, the bushing assembly device can be selected as a servo press or a hydraulic press or other machine for assembling the bushing 120. Since the specific structure and working principle of the bushing assembly device are all existing technologies and do not involve the improvements made by the present invention to the existing technologies, this embodiment will not elaborate on this.

[0054] Also, see Figure 4 In this embodiment, the first detection device is a visual detection device including a visual detection robot 210, that is, this embodiment detects the size parameters, position parameters and shape parameters of the mounting hole 111 through the visual detection device, so that the size parameters, position parameters and shape parameters of the mounting hole 111 can be detected quickly and accurately.

[0055] In addition, based on the content mentioned above, since the mounting hole 111 on the battery cover 110 is inspected immediately after the mounting hole 111 is opened in this embodiment, compared with the prior art, an assembly station for assembling the bushing 120 needs to be arranged between the processing station for opening the mounting hole 111 and the inspection station for inspecting the bushing 120, resulting in the processing station for opening the mounting hole 111 and the inspection station for inspecting the bushing 120 both need to be equipped with staff to carry out loading and unloading operations of the battery cover 110. In this embodiment, the processing station and the first inspection station can be arranged in close proximity, so that only one staff member is required at the processing station and the first inspection station. Specifically, the staff manually provides the battery cover 110 to the processing device, and manually transports the battery cover 110 from the processing device to the visual inspection device after the mounting hole 111 is processed. Therefore, this embodiment can save labor costs.

[0056] For further information, please refer to Figure 4The visual inspection device also includes a fixture 220, and the visual inspection device clamps and positions the battery cover 110 through the fixture 220, thereby ensuring that the visual inspection device can accurately detect the size parameters, position parameters and shape parameters of the mounting hole 111.

[0057] Moreover, in the present embodiment, the clamp 220 can be suitable for clamping and positioning battery covers 110 of different sizes. For example, the clamp 220 can be a clamping module including four clamping blocks 221, and the four clamping blocks 221 are arranged opposite to each other in pairs, and form a loading area for placing the battery cover 110, and the two relatively arranged clamping blocks 221 can move relative to or away from each other, so that the size of the loading area can be adjusted by controlling the stroke of the two relatively arranged clamping blocks 221, so as to adapt to battery covers 110 of different sizes.

[0058] It is understandable that the driving structure for driving the clamping block 221 to move is a prior art, and therefore, this embodiment will not elaborate on it.

[0059] Of course, in other optional embodiments, the clamp 220 may also be other clamping modules that can adjust the size of the placement area for placing the battery cover 110 , and this embodiment does not impose any specific limitation on this.

[0060] In addition, it should be noted that if Figure 3 As shown, in this embodiment, the battery cover processing method also includes:

[0061] S4 , extracting the battery cover plate 110 with the bushing 120 installed thereon, and inspecting the bushing 120 installed on the battery cover plate 110 .

[0062] That is, the present embodiment can also perform random inspection on the battery cover plate 110 installed with the bushing 120 , thereby further ensuring that the battery cover plate 110 can be accurately assembled or installed subsequently.

[0063] It is understandable that, since the upstream first detection device has already detected all battery cover plates 110 flowing downstream, subsequent spot checks on battery cover plates 110 installed with bushings 120 can ensure that the battery cover plates 110 can be accurately assembled or installed.

[0064] As described above, this embodiment can more fully ensure that the battery cover 110 can be accurately assembled or installed by combining full inspection and random inspection.

[0065] It is worth noting that, in the present embodiment, after the bushing 120 is installed, the size parameters and position parameters of the bushing 120 are detected. Since the bushing 120 is inserted into the mounting hole 111, it is possible to determine whether the shape of the bushing 120 meets the requirements by detecting the size parameters of the bushing 120. That is, the present embodiment can perform a comprehensive inspection of the bushing 120 by detecting the size parameters and position parameters of the bushing 120.

[0066] From the above, in this embodiment, the battery cover processing equipment also includes a second detection device, which is arranged at the second detection station and is configured to detect the bushing 120 on one of the battery cover plates 110 extracted from the plurality of battery cover plates 110. Specifically, this embodiment can extract one from the plurality of battery cover plates 110 sequentially removed from the assembly station, and transfer the extracted battery cover plate 110 to the second detection station, and the second detection device detects the bushing 120 on the battery cover plate 110.

[0067] It is worth noting that the second detection device can be a three-coordinate detection module or a special inspection tool or a visual detection module, etc., and this embodiment does not impose specific restrictions on this. Since the specific structure and working principle of the second detection device are all prior art, and its specific structure and working principle do not involve the improvement made by the present invention on the prior art, this embodiment will not be described in detail.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
