Description

Technical Field

[0001] The utility model relates to the field of vacuum suction cups, in particular to a vacuum suction cup for bipolar plate processing. Background Art

[0002] Bipolar plates, also known as current collectors, provide gas flow channels to prevent hydrogen and oxygen in the battery gas chamber from communicating with each other and to establish a current path between the positive and negative electrodes in series. Bipolar plates are one of the important components of fuel cells. Fuel cell technology is a promising way to generate electricity inside cars. Each fuel cell consists of hundreds of bipolar plates that separate the membrane electrode assembly and form cooling channels. The bipolar plate itself is composed of two pieces welded together. Special care must be taken during the processing and material extraction of the bipolar plate. The structural thickness is only a few millimeters compared to the thickness of graphite materials, composite materials and other solid powder materials. It is brittle, easy to break and deform, etc. The existing machine tool processing equipment cannot fix such thin workpieces, resulting in the equipment being unable to process and shape. Among them, a vacuum suction cup for bipolar plate processing with application number "CN202023068817.2" is applicable to various graphite materials, composite materials and other solid powder materials. It has low initial material cost, simple operation, high safety performance, stable production effect and product processing quality, but the vacuum suction cup still needs to be improved during use: due to the differences in the sizes of bipolar plates that need to be processed, bipolar plates of different sizes require vacuum suction cups of appropriate sizes. The vacuum suction cup cannot be adjusted according to the size of the bipolar plate, which reduces its applicability. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) A fixing seat is installed at the bottom of the support rod, and a servo motor is installed on one side of the fixing seat. When the servo motor rotates, it drives the bidirectional screw at the output end to rotate inside the fixing seat. When the bidirectional screw rotates, it drives the moving block on the surface to rotate accordingly. Since a mounting plate is installed at the bottom of the moving block, sliders are installed on both sides of the surface of the mounting plate. The sliders slide on the surface of the limit rods installed on both sides of the fixing seat, so that the rotation of the bidirectional screw drives the two moving blocks on the surface to approach each other. The moving blocks drive the mounting plates installed at the bottom to approach each other, thereby driving the vacuum suction cup installed on the surface of the mounting plate to approach each other, so that the vacuum suction cup can be adjusted accordingly according to the size of the bipolar plate, which is convenient for sucking and loading bipolar plates of different sizes, thereby improving the scope of application;

[0017] (2) Through the provided material picking assembly, vacuum suction cups are respectively installed at both ends of the surface of the mounting plate, and a connecting air pipe is installed on the top of the vacuum suction cup, which is connected to the external air source. When it is necessary to pick up the material, the air source sucks the air inside the vacuum suction cup through the connecting air pipe, so that a vacuum is formed between the vacuum suction cup and the material, which is convenient for sucking the bipolar plate. The silicone sleeve installed at the bottom of the vacuum suction cup is a multi-layer pleated structure, so that the vacuum suction cup contacts the bipolar plate through the silicone sleeve. The silicone sleeve has a certain buffer to prevent the vacuum suction cup from directly contacting the material and causing damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figure 2 The adjustment component 4 includes a fixed seat 41 installed at the bottom of the support rod 1, a servo motor 42 is fixedly installed on one side of the fixed seat 41, a bidirectional screw rod 43 is rotatably installed inside the fixed seat 41, the output end of the servo motor 42 is fixedly connected to one end of the bidirectional screw rod 43, a moving block 44 is threadedly connected to the surface of the bidirectional screw rod 43, a mounting plate 45 is fixedly connected to the bottom of the moving block 44, limit rods 46 are fixedly installed on both sides of the fixed seat 41, sliders 47 are fixedly installed on both sides of the surface of the mounting plate 45, and the sliders 47 are slidably installed on the surface of the limit rod 46.

[0034] During specific use: a fixing seat 41 is installed at the bottom of the support rod 1, and a servo motor 42 is installed on one side of the fixing seat 41. After the servo motor 42 rotates, it drives the bidirectional screw rod 43 at the output end to rotate inside the fixing seat 41. When the bidirectional screw rod 43 rotates, it drives the moving block 44 on the surface to rotate accordingly. Since a mounting plate 45 is installed at the bottom of the moving block 44, sliders 47 are installed on both sides of the surface of the mounting plate 45. The sliders 47 slide on the surface of the limit rods 46 installed on both sides of the fixing seat 41, so that the rotation of the bidirectional screw rod 43 drives the two moving blocks 44 on the surface to approach each other, and the moving block 44 drives the mounting plate 45 installed at the bottom to approach each other, thereby driving the vacuum suction cup 51 installed on the surface of the mounting plate 45 to approach, so that the vacuum suction cup 51 is adjusted accordingly according to the size of the bipolar plate, which is convenient for sucking and loading bipolar plates of different sizes, thereby improving the scope of application.

[0035] See also Figure 4 The material picking component 5 includes a vacuum suction cup 51 fixedly mounted on both ends of the surface of the mounting plate 45, the top of the vacuum suction cup 51 is fixedly connected with a connecting air pipe 52, the connecting air pipe 52 is connected to an external air source, and the bottom of the vacuum suction cup 51 is fixedly connected with a silicone sleeve 53, and the silicone sleeve 53 is a multi-layer pleated structure.

[0036] During specific use: vacuum suction cups 51 are respectively installed at both ends of the surface of the mounting plate 45, and a connecting air pipe 52 is installed on the top of the vacuum suction cup 51, and the connecting air pipe 52 is connected to an external air source. When it is necessary to take materials, the air source sucks the air inside the vacuum suction cup 51 through the connecting air pipe 52, so that a vacuum is formed between the vacuum suction cup 51 and the material, which is convenient for sucking the bipolar plate. The silicone sleeve 53 installed at the bottom of the vacuum suction cup 51 is a multi-layer pleated structure, so that the vacuum suction cup 51 contacts the bipolar plate through the silicone sleeve 53, and the silicone sleeve 53 has a certain buffer to prevent the vacuum suction cup 51 from directly contacting the material and causing damage.

[0037] See also Figure 1 , Figure 4 Two sets of drag chains 6 are arranged inside the installation cavity 2, and the connecting air pipes 52 are inserted inside the drag chains 6.

When the moving block 44 drives the mounting plate 45 to move, the mounting plate 45 drives the connecting air pipe 52 to follow the movement. The connecting air pipe 52 is installed inside the drag chain 6 so that it keeps moving neatly to avoid the connecting air pipe 52 being scattered outside and causing entanglement. The length of the drag chain 6 is greater than the adjustment range of the moving block 44, so that the moving distance of the connecting air pipe 52 is met.

[0039] See also Figure 1 Both sides of the end of the support rod 1 are fixedly connected with connecting plates 7, and the bottom of the connecting plate 7 is fixedly installed with a visual sensor 8.

[0040] During specific use: connecting plates 7 are connected to both sides of the end of the support rod 1, and the visual sensor 8 installed at the bottom of the connecting plate 7 is used to measure the size of the bipolar plate, so that the moving block 44 drives the vacuum suction cup 51 to adjust to the size corresponding to the bipolar plate.

[0041] See also Figure 1 A plurality of weight-reducing holes 9 are provided on the surface of the support rod 1 .

[0042] During specific use: a weight-reducing hole 9 is provided on the surface of the support rod 1, so as to reduce the weight of the support rod 1 while satisfying the structural strength.

[0043] See also Figure 1 The servo motor 42 and the visual sensor 8 are both controlled and connected to the control panel 3, and the control panel 3 is electrically connected to the external power supply.

[0044] During specific use: when the control panel 3 is connected to an external power source, the servo motor 42 and the visual sensor 8 are powered on and controlled to work; when the control panel 3 is disconnected from the external power source, the device stops running.

[0045] A fixing seat 41 is installed at the bottom of the support rod 1, and a servo motor 42 is installed on one side of the fixing seat 41. When the servo motor 42 rotates, it drives the bidirectional screw 43 at the output end to rotate inside the fixing seat 41. When the bidirectional screw 43 rotates, it drives the moving block 44 on the surface to rotate accordingly. Since a mounting plate 45 is installed at the bottom of the moving block 44, sliders 47 are installed on both sides of the surface of the mounting plate 45. The sliders 47 slide on the surfaces of the limit rods 46 installed on both sides of the fixing seat 41, so that the rotation of the bidirectional screw 43 drives the two moving blocks 44 on the surface to approach each other, and the moving block 44 drives the mounting plate 45 installed at the bottom to approach each other, thereby driving the vacuum suction cup 51 installed on the surface of the mounting plate 45 to approach, so that the vacuum suction cup 51 is adjusted accordingly according to the size of the bipolar plate, which is convenient for sucking and loading bipolar plates of different sizes, thereby improving the scope of application.
