Description

Technical Field

[0001] The utility model belongs to the technical field of electrode sheet processing jigs, and particularly relates to an automatic jig for electrode sheets. Background Technique

[0002] In the manufacturing industry of electrode sheets, with the development of technology, the types of products are constantly enriched, and at the same time, the requirements for product performance are also constantly increasing. Therefore, product reliability testing has become a key technical standard for evaluating product quality. In order to meet the testing requirements of various different product forms, it has become particularly crucial to develop highly adaptable testing jigs. The research and development and use of such jigs have been regarded as necessary capital expenditures by many manufacturing enterprises and have been included in the company's operating costs. Considering the current industrial environment, reliability testing jigs not only require a relatively high initial investment, but also due to the rapid technological updates, these jigs often have a relatively high replacement frequency, resulting in cost losses. Currently, the mainstream electrode sheet reliability testing jigs on the market mostly adopt a complete set of press-sheet type designs. However, due to the limitations of the materials used and their manufacturing processes, during high and low temperature tests, these jigs often have problems such as electrode deformation and insecure fixation, which in turn affect the accuracy of test results. In addition, due to their relatively complex structures, this increases the complexity of operation, making it easier to make mistakes caused by human factors during the testing process.

[0003] An electrode jig with the patent publication number of CN209125063U improves its processing efficiency. The technical solution of the utility model includes an electrode jig base, a quick-change chuck, and a clamping pull stud.

Specific embodiments

[0020] The present utility model will be further described in detail below in conjunction with the drawings and specific preferred embodiments.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "left side", "right side", "upper part", "lower part", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not represent the importance of the components, so it cannot be understood as a limitation to the present utility model. The specific dimensions adopted in this embodiment are only for illustrating the technical solution by way of example, and do not limit the protection scope of the present utility model.

[0022] Embodiment 1: When testing the electrode plate, it is necessary to fix the electrode plate for convenient testing. When the existing electrode plate fixture fixes the electrode plate, the operation is complex and the automation degree of the device is low. Referring to Figure 1 , it can be seen that an automatic electrode plate fixture includes a base 1 located at the bottom of the device. One end of the base 1 is provided with a guide block 5. The lead screw 3 passes through the guide block 5. One end of the lead screw 3 is installed on the power output end of the drive motor 2, and the other end is installed on the movable clamping member 41. A fixed clamping member 42 is also installed on the base 1. Driven by the drive motor 2, the lead screw 3 rotates to drive the movable clamping member 41 to slide on the base and close or loosen with the fixed clamping member 42, improving the automation degree of the electrode plate fixture and the clamping efficiency of the electrode plate;

[0023] During use, first, place the electrode sheet to be tested on one side of the fixed clamping member 42, close to the position of the movable clamping member 41, and get ready for the clamping operation. Next, start the driving motor 2. When the motor runs, it drives the lead screw 3 to rotate. The rotational motion of the lead screw 3 is converted into a linear motion, causing the movable clamping member 41 to slide along the base 1 towards the fixed clamping member 42. As the movable clamping member 41 moves, it gradually approaches and finally closes with the fixed clamping member 42, thereby clamping the electrode sheet between the two. If there are positioning protrusions provided in the fixing holes of the electrode sheet, it can ensure that the electrode sheet is in the correct test position when being clamped. At this time, the position of the electrode sheet can be adjusted as needed to ensure its complete alignment. After the electrode sheet is fixed, the required test procedure can be started. After the test is completed, reverse-start the driving motor 2 to make the movable clamping member 41 return to its initial position along the lead screw 3, thereby releasing the electrode sheet. Finally, take out the electrode sheet from the fixture for the next test cycle.

[0024] Embodiment 2: To facilitate the fixing of the electrode sheet, the clamping member 4 is set to a structure adapted to the electrode sheet. Referring to Figure 2 , it can be seen that after the fixed clamping member 41 and the movable clamping member 42 are closed, an electrode sheet fixing hole 43 is formed. At the same time, a positioning protrusion 431 is also provided inside the electrode sheet fixing hole 43. The positioning protrusion 431 is used to carry the electrode sheet. The design of the positioning protrusion 431 can ensure the accurate positioning of the electrode sheet in the fixing hole 43, prevent the electrode sheet from shifting or shaking during the test, thereby improving the accuracy and consistency of the test results;

[0025] Select stainless steel to make the clamping member 4. First, use a machine tool to cut, drill, and shape the stainless steel to manufacture the fixed clamping member 41 and the movable clamping member 42. Mill out the positioning protrusion inside the clamping member 4. For the positioning protrusion 431 part, special attention needs to be paid to its accuracy to ensure that it can accurately contact the electrode sheet. After the machining is completed, perform necessary surface treatment on the clamping member 4 to improve the appearance and increase the corrosion resistance. Assemble the machined fixed clamping member 41 and the movable clamping member 42 onto the base 1, and ensure that they can close smoothly to form the electrode sheet fixing hole 43. At the same time, check whether the positioning protrusion 431 can effectively support the electrode sheet. Place the electrode sheet on one side of the electrode sheet fixing hole 43, ensure that the electrode sheet can be accurately placed on the positioning protrusion 431. Start the driving motor 2, and through the rotation of the lead screw 3, make the movable clamping member 41 move towards the fixed clamping member 41 until the two components close and clamp the electrode sheet. Confirm that the electrode sheet has been correctly positioned in the fixing hole 43 and will not be displaced during the test. With the electrode sheet fixed stably, perform the required test steps. After the test is completed, operate the driving motor 2 in reverse to make the movable clamping member 41 return to its original position, thereby releasing the electrode sheet.

[0026] Embodiment 3: To ensure good stability when the movable clamping member 42 moves on the base 1, referring to Figure 1 and Figure 3 , it can be seen that a first guide block 51, a second guide block 52 and a guide frame 52 are provided on the base 1. Among them, the first guide block 51 is welded to the end of the base 1, and the second guide block 52 and the guide frame 53 are welded to the base 1. The lead screw 3 sequentially passes through the first guide block 51 and through the guide hole 521 of the second guide block 52 and the guide frame 53. A guide rail 11 is also provided on the base 1. The movable clamping member 42 is clamped on the guide rail 11. By installing the first guide block 51, the second guide block 52 and the guide frame 53 on the base 1 and allowing the lead screw 3 to pass through these guide blocks in sequence, the linear motion of the movable clamping member 42 can be effectively guided. At the same time, a handle 6 is installed on the base 1 to facilitate the movement of the electrode sheet fixture, reduce its shaking and deviation during the movement, and ensure the stability and accuracy of the movable clamping member 42 during the movement. The guide block and the guide frame are fixed to the base 1 by welding. This fixed installation method not only increases the mechanical strength of the entire system, but also can resist the influence of external forces, avoid wear or loosening caused by long-term use, and extend the service life of the equipment. The lead screw 3 passes through the guide hole 521 on the guide block and the guide frame 53, ensuring that the lead screw 3 can move smoothly along the set path when rotating, avoiding the jamming phenomenon caused by the bending or deviation of the lead screw from the track, and ensuring the smoothness when the driving motor 2 drives the lead screw 3 to rotate;

[0027] During use, prepare the base 1 and preset the installation positions on it. Weld the first guide block 51 at one end of the base 1 to ensure its stability and ability to withstand the guiding force of the lead screw 3. Weld the second guide block 52 and the guide frame 53 at the selected positions on the base 1 to ensure that there is enough distance between these three components to support the full-course guiding of the lead screw 3. Pass the lead screw 3 through the first guide block 51 in sequence, then through the guide hole 521 of the second guide block 52, and finally through the guide frame 53. One end of the lead screw 3 should be connected to the power output end of the driving motor 2, and the other end is connected to the movable clamping member 42 to ensure that the lead screw 3 can drive the movable clamping member 42 to perform linear motion. Lay the guide rail 11 on the base 1. Usually, the guide rail 11 is arranged parallel to the lead screw 3 to ensure the linear motion trajectory of the movable clamping member 42. Install the movable clamping member 42 so that it can be clamped on the guide rail 11 and can slide smoothly along the guide rail 11 driven by the lead screw 3. Start the driving motor 2 and observe whether the movable clamping member 42 can move smoothly along the guide rail 11, and check whether there is abnormal noise or jamming phenomenon. Check the movement of the lead screw 3 in the first guide block 51, the second guide block 52 and the guide frame 53 to ensure its smoothness. After confirming that all components are installed correctly and function normally, conduct a trial run to ensure the stable and reliable operation of the entire system.

[0028] Embodiment 4: The drive motor 2 is connected to an external power supply to provide power for the entire device. The drive motor 2 drives the screw rod 3 to rotate, driving the movable clamping member 42 to slide on the base 1. The drive motor 2 serves as the power source, and its rotating shaft is directly or through a coupling connected to one end of the screw rod 3. The screw rod 3 (or called the screw) is connected to the movable clamping member 42. When the motor rotates, the screw rod 3 rotates accordingly. The screw rod 3 usually has threads, and the corresponding threaded holes or nuts are provided in the cooperating movable clamping member 42. In this way, the rotation of the screw rod 3 can be converted into the linear motion of the movable clamping member 42 along the axial direction of the screw rod 3. As the screw rod 3 rotates, the movable clamping member 42 advances or retreats along the axis direction of the screw rod 3 to achieve the function of clamping or loosening the electrode sheet. The drive motor 2 is installed on the base 1 and ensured that its position is stable and can withstand the vibration generated during the operation of the motor. Connect the power cord of the motor to the external power supply to ensure that the motor can obtain sufficient power supply. Install one end of the screw rod 3 on the power output end of the drive motor 2 to ensure that the connection between the two is tight and concentric. The other end passes through the guiding block 5 fixed on the base 1 and is connected to the movable clamping member 42. Threaded holes or nuts matching the screw rod 3 should be designed on the movable clamping member 42. Install the guide rail 11 on the base 1 to ensure that the movable clamping member 42 can smoothly move on the guide rail 11. The installed guiding block 5 includes the first guiding block 51, the second guiding block 52 and the guiding frame 53 to ensure that the screw rod 3 can smoothly slide therein and maintain straightness. Connect to the external power supply, start the drive motor 2, observe whether the movable clamping member 42 can smoothly move along the axial direction of the screw rod 3, check whether the movement of the movable clamping member 42 is smooth and whether there is jamming. Place the electrode sheet and test whether the fixture can accurately clamp the electrode sheet to ensure its reliable fixation.
