Description

Technical Field

[0001] The utility model relates to the technical field of integrated busbar processing, in particular to an automatic pressure maintaining machine. Background Art

[0002] The CCS integrated busbar is a key component that integrates the conductive busbar, control circuit and other components in the battery module into one module, realizing high-voltage series and parallel connection of battery cells, as well as battery temperature sampling, battery cell voltage sampling, and overcurrent fuse functions. By integrating these components, the CCS integrated busbar can effectively manage and distribute energy.

[0003] During the pressing process of the CCS integrated busbar, a holding press is required to hot-press the components into a whole. Since the components are of different sizes and shapes, it is difficult to extrude them evenly during hot pressing, resulting in unstable local connections and affecting the overall quality of the product. Therefore, further improvements can be made. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides the following technical solutions: an automatic pressure-maintaining machine, comprising a machine base, a bracket fixedly installed on the top of the machine base, a hydraulic cylinder fixedly installed on the top front side of the bracket, a base plate fixedly installed on the telescopic end of the hydraulic cylinder, a pressure plate fixedly installed on the bottom of the base, an operating area is provided on the front side of the machine base, a processing table is provided on the top of the machine base and directly below the base plate, a plurality of mounting holes are opened inside the pressure plate, and a pressure rod assembly is provided in the mounting hole.

[0005] As an optimization, the pressure rod assembly includes a lower pressure rod inserted in the mounting hole, a baffle is fixedly installed on the outer side of the middle part of the lower pressure rod, a fixing ring is fixedly installed on the top of the mounting hole, a compression spring is fixedly installed between the baffle and the fixing ring, and the compression spring is sleeved on the outer side of the lower pressure rod. The compression spring's own elastic force will make the lower pressure rod squeeze on the lower component, and can be lifted to different heights according to different parts of the component, and thus can adapt to the shape of different components, squeeze different parts of the component, and achieve uniform pressing.

[0006] As an optimization, a protective pad is fixedly installed at the bottom end of the downward pressure rod to prevent the downward pressure rod from directly contacting the component and to avoid damage to the surface of the component due to overpressure.

[0007] As an optimization, the protective pad is made of rubber.

[0008] As an optimization, limiting sleeves are fixedly installed on the front side of the bracket and on both sides of the hydraulic cylinder, and a guide rod is fixedly installed on the top side of the base plate corresponding to the limiting sleeve, and the guide rod is slidably inserted in the limiting sleeve. When the base plate is driven up and down by the hydraulic cylinder, the guide rod will slide along the inner wall of the limiting sleeve, and then it will play the role of limiting guide, ensuring vertical and accurate pressing.

[0009] As an optimization, a heating tube is provided inside the processing table, and temperature sensors are provided on both sides of the processing table. The temperature sensors and the heating tube signals are connected. The surface of the processing table can be heated by the heating tube to improve the efficiency of component pressing. The induced temperature is then detected in real time by the temperature sensor to avoid damage to the components due to temperature overload.

[0010] As an optimization, the heating tube is in an "S" shape that bends back and forth.

[0011] The beneficial effects of the utility model are:

[0012] This automatic pressure-maintaining machine will drive the pressure plate downward on the processing table by starting the hydraulic cylinder, so that the pad will contact the surface of the component and move upward relative to the pressure plate, thereby compressing the compression spring, thereby being able to adapt to different component surfaces and evenly squeeze according to the uneven thickness of the component surface, so that the components can be evenly pressed to avoid local uneven pressing that affects product quality.

The compression spring 12 itself causes the lower pressure rod 9 to be squeezed on the lower component according to its own elastic force, and can be lifted to different heights according to different parts of the component, thereby being able to adapt to the shape of different components, squeeze different parts of the component, and achieve uniform pressing;

[0022] See also Figure 2-3 , a pad 13 is fixedly installed at the bottom end of the pressing rod 9, and the pad 13 is made of rubber. The pad 13 prevents the pressing rod 9 from directly contacting the component, thereby preventing overpressure from damaging the surface of the component;

Temperature sensors 17 are provided on both sides of the processing table 7, and the temperature sensors 17 and the heating tube 16 are connected by signal. The surface of the processing table 7 can be heated by the heating tube 16 to improve the efficiency of component pressing. The induced temperature is then detected in real time by the temperature sensor 17 to avoid damage to the components due to temperature overload.

[0025] When in use, first place each component on the processing table 7, then start the heating tube 16 to heat it, and then use the hydraulic cylinder 3 to drive the bottom plate 4 to move downward, so that the pressing plate 5 will be pressed downward on the processing table 7. At this time, the pad 13 will first contact the component, so it will compress the compression spring 12 upward through the baffle 10, and then it can be lifted to different distances on the surface of the component, and can be pressed on the entire surface of the component, so that the pressing is more uniform;

[0026] At the same time, the temperature sensor 17 can detect the induced temperature in real time. When it is detected that the temperature is too high, the current at the heating tube 16 will be disconnected to avoid temperature overload and damage to components, thereby playing a protective role.

[0027] To sum up, the automatic pressure-maintaining machine, by starting the hydraulic cylinder 3, will drive the pressure plate 5 to press downward on the processing table 7, so that the protective pad 13 will contact the surface of the component and move upward relative to the pressure plate 5, so the compression spring 12 will be compressed, and thus it can adapt to different component surfaces and squeeze evenly according to the uneven thickness of the component surface, so that the components can be evenly pressed to avoid local uneven pressing affecting product quality.
