Description

Technical Field

[0001] This invention relates to the field of battery plate airtightness testing technology, specifically to a centering slide mechanism. Background Technology

[0002] Based on their materials, electrode plates are mainly classified into three categories: metal electrode plates, composite plates, and graphite plates. Metal electrode plates are lightweight and thin. During the processing of metal electrode plates, especially in the development and trial production of new fuel cell bipolar plates, testing for airtightness is a crucial process. In automated production, robotic arms are typically used to pick up the electrode plates and feed them into the testing device. During this process, the matching and positioning of the equipment and multiple electrode plates is of paramount importance.

[0003] Existing centering slide mechanisms, due to their unidirectional push plate design, are prone to electrode plate warping during positioning, leading to inaccurate positioning. Furthermore, electrode plate warping can cause contact sensors to fail to detect the electrode plate, resulting in machine misidentification and malfunction. Summary of the Invention

[0032] Please see Figure 1-5 As shown, the present invention is a centering slide mechanism, including a centering platform 1, a support platform 2, pads 4, a push plate 5, and a guide shaft 6. The support platform 2 is fixedly mounted on the centering platform 1, and a limiting plate 3 is fixedly mounted on the top surface of the support platform 2, forming a placement groove between the two limiting plates 3; the pads 4 are fixedly mounted on the centering platform 1, and two pads 4 are respectively located on both sides of the support platform 2; the push plate 5 is connected to a linear drive assembly, and the push plate 5 and the support platform 2 are respectively located on both sides of one of the pads 4; the guide shaft 6 is connected to the centering platform 1 through a bracket, and the guide shaft 6 is located between the pads 4 and the support platform 2, and a positioning part 7 is fixedly mounted on the guide shaft 6, one end face of which is perpendicular to the push plate 5.

[0033] Please see Figure 1-4In one embodiment of the present invention, the centering platform 1 serves as the worktable and support body of the centering slide mechanism. The bearing platform 2 is fixedly mounted on the centering platform 1, and limiting plates 3 are fixedly mounted at both ends of the top surface of the bearing platform 2. A placement groove is formed between the two limiting plates 3 to accommodate workpieces. There can be multiple placement grooves, with adjacent placement grooves sharing a limiting plate 3. For example, four placement grooves can be arranged consecutively to allow for the sequential placement of multiple workpieces, improving work efficiency. Furthermore, a removal notch 10 can be provided on one side of the limiting plate 3, located on the side of the workpiece, facilitating easy removal of the workpiece. One placement groove corresponds to one set of removal notches 10, and one set of removal notches 10 can consist of one, two, or three notches.

[0034] Please see Figure 1-4 In one embodiment of the present invention, the pad 4 is fixedly disposed on the centering platform 1, and two pads 4 are respectively disposed on both sides of the support platform 2. The pad 4 may include a first pad and a second pad. The first pad is located on one side of the support platform 2, and a blocking strip is provided at the end of the top surface of the first pad away from the support platform 2 to block the bipolar plate workpiece. The second pad is located on the other side of the support platform 2, and a sensor is provided on the second pad to detect the presence or absence of the workpiece. The top surface of the pad 4 is flush with the top surface of the support platform 2 to form a plane for placing the bipolar plate workpiece.

[0035] Please see Figure 1-4 In one embodiment of the present invention, the push plate 5 is connected to a linear drive assembly, and the push plate 5 and the support platform 2 are respectively located on opposite sides of one of the pad blocks 4. That is, the support platform 2 is located on the upper side of the second block, and the push plate 5 is located on the lower side of the second block; the linear drive assembly may include a linear guide rail, which is fixedly mounted on the centering platform 1, the push plate 5 is fixedly connected to a mounting plate, the mounting plate is fixedly connected to a slider, and the slider slides in cooperation with the linear guide rail, so that the push plate 5 can move linearly.

[0036] Please see Figure 1-4 In one embodiment of the present invention, the guide shaft 6 is connected to the centering platform 1 via a bracket. The guide shaft 6 is located between the pad 4 and the support platform 2, and can be arranged parallel to the push plate 5. A positioning part 7 is fixedly provided on the guide shaft 6, and one end face of the positioning part 7 is perpendicular to the push plate 5. In use, one end face of the positioning part 7 and one side face of the push plate 5 respectively align and position the workpiece in the X and Y directions, ensuring the positioning accuracy of the workpiece.

[0037] Please see Figure 1-4In one embodiment of the present invention, since the length, width, and other dimensions of different battery plates are inconsistent, it is necessary to change the corresponding alignment slide when testing different plates, which is cumbersome and inefficient. To solve this problem, the pad 4 and the support platform 2 are detachably connected to the lifting blocks 8. The pad 4 and the support platform 2 are movably connected to the corresponding lifting blocks 8. That is, at least one stepped surface is provided on the first block, and a lifting block 8 can be set at the stepped surface. Corresponding lifting blocks 8 can be set on the support platform 2 and the second block. When the lifting blocks 8 are not installed, it can be used to test one model of product. When the lifting blocks 8 are installed, the raised plane can be used to place and test another model of product. Furthermore, multiple stepped surfaces can be provided, and lifting blocks 8 of different heights can be set to form a plane for placing the plates.

[0038] Please see Figure 1-4 In one embodiment of the present invention, to achieve positioning for different electrode plate products, the positioning part 7 can be configured to be movably sleeved with the guide shaft 6. This movable sleeve connection can be a sliding sleeve or a threaded sleeve, allowing the position of the positioning part 7 to be adjusted according to the width of the product. Alternatively, the positioning part 7 can be configured to include a sleeve and an end plate that are fixedly connected. The height of the guide shaft 6's fixed point matches the height of the top surface of the support platform 2 before the installation of the lifting block 8, and the end face of the sleeve provides positioning for the workpiece in this state. The height of the apex of the outer circular surface of the sleeve matches the height position after the installation of the lifting block 8, and the end plate, connected to the sleeve, provides positioning for the workpiece, thereby accommodating products of different specifications. The positioning part 7 can also be divided into multiple segments to accommodate more product models.

[0039] Please see Figure 1-5 In one embodiment of the present invention, the end face of the sleeve can be further divided into multiple parts of different heights. During use, the sleeve is rotated so that the parts of different heights are positioned on the upper side and contact the workpiece, thus positioning the workpiece. Alternatively, the end face of the sleeve can be configured into two parts of different heights, with a bevel between the two parts (e.g., ...). Figure 5 When placing the workpiece, the left part of the sleeve end face is located on the upper side, thus providing a larger space between it and the limiting plate 3 on the other side, making it easier to place the workpiece. After placing the workpiece, the sleeve is rotated so that the right part of the sleeve end face contacts the workpiece, improving the positioning accuracy of the workpiece.

[0040] Please see Figure 1-4In one embodiment of the present invention, to ensure the accuracy of the sensor in identifying the electrode plate, a mounting hole 9 is provided on a push block near the push plate 5, and an upward-facing laser sensor is installed in the mounting hole 9. When the electrode plate is placed on the centering mechanism, the mounting hole 9 forms a closed space, free from other objects that could cause false sensing, thus ensuring the accuracy of electrode plate identification. Furthermore, the use of a photoelectric sensor provides a longer range than existing proximity switches, allowing the sensor to detect the presence of the electrode plate even if it warps.

[0041] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the scope of the claims.
