As the number of production lines increases, the number of defective products will also increase. There is a large manpower gap if only staff members perform real-time maintenance on each production line. If defective products are allowed to remain on the production line, the efficiency of the production line will be affected. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the embodiments of the utility model and the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0025] In the embodiment of the utility model, the NG cache structure is applied to the battery cell filling production line. The main cache objects include unqualified battery cells that have been filled with liquid, unqualified battery cells that have not been filled with liquid, etc. The battery cells need to be positioned and stored when loaded to keep the posture of the battery cells stable and avoid the risk of electrolyte leakage.

[0026] The utility model embodiment provides a production line NG buffer structure, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , including a slide rail 1 embedded in the production line structure, a chassis 2 slidingly arranged on the slide rail 1 and a sensor. The chassis 2 is equipped with a material box 7 for positioning and loading NG products. The chassis 2 slides along the slide rail 1 toward the outside of the production line to transfer the NG products loaded in the material box 7 to the outside.

[0027] In the present application, the cache structure is implemented based on the production line. A accommodating cavity can be set at an appropriate position of the production line, and an NG cache structure can be installed to temporarily store defective products with NG detection results in the production line, thereby having a buffering effect on the production line and reducing the production line pressure caused by the accumulation of defective products on the production line.

[0028] It is feasible that the slide rail 1 is loaded in the accommodating cavity in an embedded manner, and the chassis 2 is slidably installed on the slide rail 1. An opening and closing door can be provided at the port of the accommodating cavity to close the accommodating cavity during operation and open the opening and closing door when emptying the cache, thereby distinguishing the two operating states.

[0029] In the embodiment of the present application, a loading area 21 is provided on the chassis 2, in which a material box 7 is carried. The material box 7 is used to position and load NG products. The NG products can be loaded into the material box 7 by a robot. When the material box 7 is full or about to be full, the staff can clear the cache and take out the NG products, thereby realizing the transfer of NG products on the production line to the outside, maintaining the normal operation of the production line, and eliminating the impact caused by the accumulation of defective products.

[0030] In a feasible embodiment, taking the battery cell as an example of the NG product, the material box 7 has a built-in grid plate, and the battery cell is placed in the gap of the grid plate. Multiple battery cells are separated by the grid plate and are positioned and supported by the grid plate to prevent tipping, skewing, etc.

[0031] The grid gap can be adjusted according to the thickness of the battery cell, or selected according to the thickness of the battery cell on the current production line.

[0032] In another possible embodiment, see Figure 4 NG products take the battery cell as an example. Multiple partitions with uniform spacing are symmetrically arranged on the two side walls of the material box 7, and the battery cells are inserted into the gaps between the partitions. The two side ends of the multiple battery cells are limited, the middle is separated and parallel, and they are positioned and supported by the partitions without tipping or skewing.

[0033] In an embodiment of the present application, full load detection of NG products in the material box 7 can be achieved by a sensor. The sensor is set corresponding to the material box 7, and the sensor is used to detect the number of NG products in the material box 7.

[0034] In a feasible embodiment, the sensor is a weighing sensor 4, and the material box 7 is loaded in the loading area 21 of the chassis 2 through one or more weighing sensors 4. By weighing the material box 7, it is determined whether the material box 7 is fully loaded or about to reach a fully loaded state.

[0035] Specifically, a weighing sensor 4 is respectively arranged at the four corners of the loading area 21, and four weighing sensors 4 are installed corresponding to the four corners of the material box 7. The four weighing sensors 4 have a stable supporting effect on the material box 7, and can synchronously obtain the weight data of the material box 7, which is relatively accurate.

[0036] It can be understood that the number of battery cells in the material box 7 is fixed, and there is a weight difference between the injected battery cells and the uninjected battery cells, but it is small compared to the weight of the battery cells. At the same time, when the NG product is placed in the material box 7, the positioning of the product can be clear and have its weight data, which is conducive to judging the loading condition of the material box 7 by the overall weight.

[0037] In another feasible embodiment, the sensor is an image recognition module, which includes a camera unit for collecting images and a recognition unit for recognizing the content of the image. The camera unit is arranged directly above the slide rail 1, and the camera unit is electrically connected to the recognition unit. Image recognition technology is a technical means that is easily available to ordinary technicians in this field and will not be described in detail here.

[0038] The number of NG products loaded in the material box 7 can be determined by image recognition, and the loading state of the material box 7 can be directly determined. It can be understood that the camera unit can be arranged directly above a branch rail of the slide rail 1 without affecting the transfer of NG products by the robot.

[0039] In this application, when the sensor detects the number of NG products, it can prompt and warn the staff, who will then clear the cache.

[0040] An alarm may be provided, which is electrically connected to the sensor and includes indicator lights and a voice unit, wherein the indicator lights may include multiple groups, indicating different states respectively, which may be distinguished by colors; the voice unit may directly broadcast corresponding voices to call the staff to the corresponding production line to perform cache clearing operations.

[0041] It should be clear that when the manipulator is putting in NG products, the chassis 2 should be in a relatively stable state to ensure that the NG products can be stably loaded into the material box 7; similarly, when the sensor is detecting, the chassis 2 should also be in a relatively stable state to ensure that the detection results are more stable and accurate. Therefore, in this application, a locking structure is set at the rear beam 3 of the slide rail 1 to lock the chassis 2 to achieve the fixed position of the chassis 2 under certain circumstances.

[0042] In an embodiment of the present application, the slide rail 1 includes two branch rails, and a rear beam 3 is provided at the rear ends of the two branch rails. A locking structure is provided between the rear beam 3 and the chassis 2 to fix the position of the chassis 2 when the material box 7 is loaded with NG products.

[0043] In a feasible embodiment, an electromagnet is mounted on the rear beam 3 , and a magnetically attracted positioning rod 22 is provided at the rear end of the chassis 2 , so that the positioning rod 22 is magnetically attracted by the electromagnet, thereby fixing the position of the chassis 2 .

[0044] It can be understood that when the NG product is loaded, the electromagnet attracts the positioning rod 22 to position the chassis 2 so that it does not shake or move. After the loading is completed, the chassis 2 can be released, but based on the sliding friction between the slide rail 1 and the chassis 2, the chassis 2 will not have a large displacement tendency and will remain in place. When the subsequent loading operation is performed, it can be directly positioned by magnetic attraction.

[0045] When a weighing sensor is used, the electromagnet can be turned off during weighing so as not to affect the weighing sensor 4. The weighing is not performed during the loading operation, and the weighing conditions are met after the loading is completed.

[0046] In another feasible embodiment, a snap-in notch is provided in the middle of the rear beam 3, a clip 31 is built into the snap-in notch, a positioning rod 22 is provided at the rear end of the chassis 2, an elastic clip 24 is provided in the middle of the positioning rod 22 corresponding to the snap-in notch, and the elastic clip 24 snaps with the clip 31 in the snap-in notch to fix the position of the chassis 2.

[0047] It can be understood that the chassis 2 and the rear beam 3 are positioned by a snap-fit ​​structure, and the position of the chassis 2 is always relatively stable, so loading and weighing operations can be carried out directly; when the cache needs to be cleared, the snap-fit ​​can be released by external force.

[0048] For example, see Figure 3 The rod of the elastic clamp 24 is elastic, and the two elastic clamps 24 are arranged in a back-to-back manner, and the gap between them can be an elastic space to restrict each other; when buckled, it can be pushed in forcefully to achieve buckle fit; when released, it can be pulled out forcefully to release the buckle. Based on this, a handle 23 can be set at the front end of the chassis 2 for pulling the chassis 2 to run in the slide rail 1.

[0049] In the embodiment of the present application, a slideway 11 is provided on the opposite side walls of the two branch rails, a front axle 6 is provided at the front end of the chassis 2, and front wheels 61 are provided at both ends of the front axle 6 in the slideway 11; a rear axle 5 is provided at the rear end of the chassis 2, and a rear wheel group is provided at both ends of the rear axle 5 in the slideway 11, and the rear wheel group includes a first wheel 51 and a second wheel 52, and the first wheel 51 and the second wheel 52 are parallel.

[0050] The chassis 2 is mounted on the front axle 6 and the rear axle 5, and a plurality of wheels are arranged on the rear axle 5, so that the overall contact between the chassis 2 and the slideway 11 is more stable. Furthermore, a slideway valve 12 is arranged at the front end of the slideway 11 to prevent the chassis 2 from falling off the slideway 1.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device comprising the elements.

[0052] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation methods, and the specific embodiments of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
