Description

Technical Field

[0001] The utility model belongs to the technical field of negative pressure formation of battery cells, and in particular relates to a positioning tool for a negative pressure formation nozzle. Background Art

[0002] In the production process of battery cells, battery cell injection is a very important step. After the battery cell injection, a negative pressure formation process is usually required. During the formation process, in order to avoid battery cell swelling and lithium deposition on the battery cell interface, the position of the negative pressure nozzle must be aligned with the injection port, and the gas generated in the formation process must be discharged in time. If the nozzle position is not aligned with the injection port, the battery cell will swell, black spots will appear on the interface, and the liquid loss will increase, seriously affecting the battery cell life and charge and discharge capabilities.

[0003] In the prior art, whether the position of the negative pressure nozzle is aligned with the liquid injection port is mostly determined by manual visual inspection. However, manual visual inspection is easily affected by external uncertain factors, which may lead to errors in the detection results and thus affect the production efficiency and quality of the battery cells.

[0035] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0036] In the description of this application, it should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0037] Example 1:

[0038] This embodiment provides a forming negative pressure nozzle positioning tool, including:

[0039] The frame 1 is provided with a plurality of positioning holes 2 arranged equidistantly along a first direction X;

[0040] Several detection components are respectively installed below each positioning hole 2;

[0041] The detection components include:

[0042] The fixing seat 3 is installed below the positioning hole 2;

[0043] The sliding rod 4 is movably mounted in the fixing base 3 along the second direction Z;

[0044] The reset member 5 is installed in the fixing seat 3 and is used to reset the slide rod 4;

[0045] The detection sensor 6 is installed on the fixing base 3 and is used to detect whether the sliding rod 4 moves along the second direction Z.

[0046] In the present technical solution, before the negative pressure formation of the battery cell is carried out, the positioning tool is first placed in the formation storage position. The positioning hole 2 provided on the frame 1 is used to simulate the injection hole of the battery cell to be negatively pressure formed. The number of the positioning holes 2 is several and they are arranged equidistantly along the first direction X, so as to simulate multiple injection holes of the battery cell to be negatively pressure formed at the same time. The fixing seat 3 of the detection component is installed on the frame 1 and is located below the positioning hole 2. A through hole 11 is provided in the fixing seat 3 along the second direction Z. The through hole 11 is connected to the positioning hole 2. The slide bar 4 can be movably installed in the through hole 11 along the second direction Z. The reset member 5 is installed in the through hole 11 for resetting the movement of the slide bar 4.

[0047] A power supply port and a communication port are provided on the frame 1. The power supply port is used to supply power to the detection sensor 6 and other electrical components in the tooling, and the communication port is used to communicate with the host computer. The communication method can adopt RS485, 232 and other communication methods. The staff can judge the detection results through the host computer and perform periodic nozzle positioning detection operations.

[0048] When performing the suction nozzle positioning detection operation, the negative pressure forming module is controlled by an external driving device to move downward along the second direction Z, so that the multiple suction nozzles of the negative pressure forming module are respectively in contact with each positioning hole 2. When the suction nozzle is plugged into the positioning hole 2, the suction nozzle will abut against one end of the slide rod 4 and push the slide rod 4 to descend along the second direction Z. The other end of the slide rod 4 extends outward from the fixed seat 3 and appears on the detection path of the detection sensor 6.

[0049] The detection sensor 6 is a photoelectric sensor, which can be a laser sensor or a slot-type photoelectric switch. When the detection sensor 6 detects an object on the detection path, the detection signal of the detection sensor 6 changes and is output to the host computer. The host computer determines that the nozzle positioning is accurate. Conversely, if the detection sensor 6 does not detect an object on the detection path, the detection signal of the detection sensor 6 does not change, and the host computer determines that the nozzle positioning is inaccurate. After the nozzle contacts the positioning hole 2 for a certain period of time, the external drive device controls the negative pressure generation module to move upward in the second direction Z to separate the nozzle from the positioning hole 2. The reset member 5 drives the slide bar 4 to reset, and the nozzle positioning detection operation is completed.

[0050] In summary, the nozzle positioning fixture simulates the contact between the battery cell injection hole and the nozzle during the negative pressure formation process by allowing the positioning hole 2 to contact the nozzle. The detection component is installed below the positioning hole 2. If the nozzle can accurately dock with the positioning hole 2, it will push the slide bar 4 to move. At the same time, the detection sensor 6 detects the movement of the slide bar 4, and the output signal changes, judging that the nozzle positioning is accurate. If the nozzle cannot accurately dock with the positioning hole 2, the slide bar 4 does not move, and the output signal of the detection sensor 6 does not change, judging that the nozzle positioning is inaccurate. The nozzle positioning fixture has a simple structure and is easy to use. It does not require manual inspection, effectively improving the detection efficiency and detection accuracy of the nozzle positioning, and reducing the probability of false detection and missed detection.

[0051] Example 2:

[0052] This embodiment provides a forming negative pressure nozzle positioning tool, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0053] Furthermore, the frame 1 includes:

[0054] A plurality of movable brackets 7, wherein the plurality of movable brackets 7 are mounted on the frame 1 so as to be movable along a third direction Y;

[0055] Among them, a plurality of positioning holes 2 are respectively provided on each movable bracket 7 , and the fixing seat 3 is installed on the movable bracket 7 .

[0056] In this technical solution, multiple mobile brackets 7 are arranged equidistantly along the third direction Y, and several positioning holes 2 are provided on each mobile bracket 7 to simulate multiple rows of battery cell packs equidistantly along the third direction Y, thereby meeting the positioning and detection requirements for different numbers of negative pressure nozzles. In addition, each mobile bracket 7 can be moved along the third direction Y, thereby adjusting the spacing between them and effectively improving adaptability.

[0057] Furthermore, it also includes:

[0058] Guide rail 8, guide rail 8 is installed on frame 1;

[0059] Slide 9, slide 9 is mounted on the guide rail 8 so as to be movable along the third direction Y;

[0060] The movable bracket 7 is installed on the slide 9 .

[0061] This structural design makes the movement of the mobile bracket 7 in the third direction Y more stable and smooth, effectively reducing the vibration and noise generated by the mobile bracket 7 during movement. It is worth mentioning that the driving mechanism for controlling the movement of the mobile bracket 7 can be an electric cylinder or a screw module. The motor of the electric cylinder or screw module is communicatively connected to the host computer. The operator can control the operation of the driving mechanism by operating the host computer, thereby driving the mobile bracket 7 to move and adjust.

[0062] Furthermore, the mobile bracket 7 is detachably mounted on the slide 9. The mobile bracket 7 and the slide 9 are fixedly connected by setting fasteners to ensure a firm connection between the mobile bracket 7 and the slide 9, while facilitating disassembly and assembly by the staff, which is helpful for subsequent replacement and maintenance.

[0063] Furthermore, the fixed base 3 is detachably mounted on the mobile bracket 7. The fixed base 3 and the mobile bracket 7 are also fixedly connected by setting fasteners to ensure that the connection between the detection component and the mobile bracket 7 is firm, and the staff also maintains the various components of the detection component.

[0064] Example 3:

[0065] This embodiment provides a forming negative pressure nozzle positioning tool, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0066] Furthermore, the detection component also includes:

[0067] The sensing piece 10 is installed at the end of the sliding rod 4 and is used to enter the detection path of the detection sensor 6.

[0068] The fixing seat 3 defines a through hole 11 , the axis of the through hole 11 coincides with the axis of the positioning hole 2 , and the sliding rod 4 is disposed in the through hole 11 .

[0069] In this technical solution, one end of the slide bar 4 is exposed from the fixing base 3 through a through hole 11, and a sensing plate 10 is provided on the end. The sensing plate 10 can be integral with the slide bar 4 or removably mounted on the slide bar 4 via fasteners. When the suction nozzle pushes the slide bar 4 downward in the second direction Z, the sensing plate 10 moves into the detection path of the photoelectric sensor, causing the detection signal of the photoelectric sensor to change. This structural design ensures that when the suction nozzle is accurately positioned, the sensing path of the photoelectric sensor is completely blocked, and the detection signal of the photoelectric sensor will change, effectively improving detection accuracy and avoiding the possibility of false detection.

[0070] Furthermore, there are multiple detection sensors 6 arranged in a ring array on the fixing base 3; there are also multiple induction plates 10, which are arranged one-to-one with each detection sensor 6. Through this structural design, multiple detection sensors 6 are used in a one-to-one correspondence with multiple induction plates 10, which can reduce the detection errors that may occur due to a single detection sensor 6 and increase the redundancy of the tooling. If one detection sensor 6 malfunctions or fails, the other detection sensors 6 can continue to work normally, ensuring the reliability of nozzle positioning detection.

[0071] Example 4:

[0072] This embodiment provides a forming negative pressure nozzle positioning tool, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0073] Furthermore, the reset member 5 is a spring.

[0074] In this technical solution, if Figure 3 As shown, the spring is sleeved on the slide rod 4, and one end of the spring abuts against the slide rod 4, and the other end abuts against the inner wall of the through hole 11 of the fixing seat 3. The suction nozzle and the positioning hole 2 are accurately docked to push the slide rod 4 downward along the second direction Z. At the same time, the spring is compressed. After the suction nozzle is separated from the positioning hole 2, the spring recovers and pushes the slide rod 4 upward along the second direction Z, thereby realizing the reset of the slide rod 4.

[0075] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.
