Description

Technical Field

[0001] The utility model belongs to the technical field of stamping, and in particular relates to an insulating PC vertical embossing device. Background Art

[0002] At present, my country's power lithium battery industry has entered a critical stage of industrialization construction and promotion and application, and the industrialization process of power lithium batteries has taken an international leading position. Power batteries are also the part that consumers pay the most attention to. They directly determine the vehicle's cruising range. The quality, safety, performance and reliability of power batteries are directly related to the user experience of pure electric vehicles.

[0003] Among them, insulating PC is particularly widely used. The application and role of insulating flame-retardant polycarbonate PC film in lithium batteries mainly include the following aspects:

[0004] Electrical isolation: Since PC film has excellent insulation properties, it can effectively electrically isolate different components inside the battery and between the battery and the external environment, preventing short circuits and ensuring that current flows along the designed path. Safety protection: With good flame retardancy and heat resistance, it can prevent the spread of fire or slow down the burning speed under extreme conditions, thereby improving the safety of the lithium battery system and reducing the risk of thermal runaway.

[0005] Mechanical support and fixation: used to make various brackets, spacers and other structural components in battery modules, battery cells and PACKs. They can provide the necessary mechanical strength, support and fix the position of internal battery components, and maintain structural stability.

[0006] Waterproof and moisture-proof: High-quality PC films tend to have lower water absorption rates, which can reduce the impact of moisture on battery performance to a certain extent. When used with special waterproof glue, it can enhance the overall waterproof effect.

[0007] Dimensional stability: PC film is resistant to bending, tearing and cracking, which helps to ensure that it maintains good shape and dimensional stability during long-term use of the battery and avoids safety hazards caused by deformation.

[0008] Meeting special requirements: In response to the special needs of new energy vehicle batteries, halogen-free flame-retardant PC / ABS materials can also be used in battery shell brackets and other parts. This type of composite material takes into account the requirements of lightweight and high flame retardancy, which helps to improve the overall performance of electric vehicles.

[0009] Most of the existing insulating PCs have a flat appearance and limited use environment. Generally, vertical bosses are pressed out on the insulating PCs by stamping equipment to adapt to the use environment with protrusions or that needs to be wrapped. When using stamping equipment for stamping, it is necessary to conduct random inspections on the stamped insulating PCs. Generally, the inspectors use inspection tools such as micrometers to inspect the insulating PCs and the boss sizes on the insulating PCs. Manual inspection is time-consuming and laborious. Secondly, it requires training to conduct inspections, which increases labor costs. Utility Model Content

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 5 As shown, an insulating PC vertical embossing device in one embodiment of the utility model, the design and precision of the mold are crucial in the embossing process. The mold usually includes a concave mold 11 and a convex mold 22 corresponding to the positive and negative, which need to be accurately designed and manufactured according to the characteristics of the PC material, the shape and size requirements of the product to ensure that the insulating PC 31 after embossing has a clear outline and distinct layers.

[0032] A cavity 13 is provided in the die 11, a punch head 23 matching the cavity 13 is fixedly connected to the bottom of the punch 22, and the insulating PC 31 is placed on the die 11 by a conveying device or manually and aligned with the die 11. A punch seat 21 is fixedly connected to the punch 22, and a lifting device such as a hydraulic cylinder is provided on the punch seat 21 to drive the punch 22 to rise and fall for stamping.

[0033] During stamping, the lifting device drives the punch seat 21 and the punch 22 to move downward, and the punch head 23 moves to the top of the corresponding insulating PC 31, that is, the insulating PC 31 at this location can be stamped into the cavity 13 to form a boss 32. After the stamping is completed, the punch 22 and the punch seat 21 rise under the action of the lifting device, and the stamped insulating PC 31 is removed from the die 11.

[0034] Preferably, since PC material has a certain hardness and toughness, the ideal relief effect can be achieved without damaging the material itself by adjusting the pressure of the lifting device. Too much or too little pressure may lead to unclear indentation or cracking.

[0035] For some thermoplastic materials such as PC, the material may need to be preheated during the embossing process to improve its plasticity and fluidity. At the same time, the temperature of the mold must be controlled to prevent the material from softening and deforming due to excessively high temperature or from becoming difficult to emboss due to excessively low temperature.

[0036] The speed and time parameters of the lifting device during the embossing process also directly affect the quality of the final product. Rapid and short-term pressure application can reduce the internal stress accumulation of the material and reduce deformation. The appropriate pressure holding time helps to form a stable and moderately deep embossing effect.

[0037] A limiting groove 42 is provided in the concave die 11, and a lifting block 41 is provided in the limiting groove 42. A first spring 43 is fixedly connected between the lifting block 41 and the bottom wall of the limiting groove 42. The limiting groove 42 can protrude from the upper end surface of the concave die 11 under the action of the first spring 43, and the insulating PC31 is located above the lifting block 41. During stamping, the lifting block 41 moves downward into the limiting groove 42. After the stamping is completed, when the punch head 23 no longer presses the insulating PC31, the lifting block 41 can automatically lift the insulating PC31 under the action of the first spring 43, so that the boss 32 is separated from the concave cavity 13, and the insulating PC31 is easy to remove.

[0038] The convex mold 22 is fixedly connected with a clamping plate 24 around its periphery. A buffer portion 25 is provided at one end of the clamping plate 24 close to the convex mold 22. The convex mold 22 can drive the clamping plate 24 to move downward. When the insulating PC 31 is offset on the concave mold 11, the insulating PC 31 offset outside the range of the concave mold 11 can be adjusted to the concave mold 11 through the clamping plate 24 and the buffer portion 25. The accuracy of the embossing position can be guaranteed. In batch production, it can be ensured that the embossing position can accurately fall on the preset area each time.

[0039] A receiving groove 52 is provided in the die base 12, a detection fixture 51 is slidably connected in the receiving groove 52, a detection groove 55 matching the height of the insulating PC 31 is provided in the detection fixture 51, and a detection platform 56 matching the boss 32 is provided in the detection groove 55. A support plate 61 is fixedly connected to the detection fixture 51, a measuring plate 62 is provided on the support plate 61, and a scale line 63 is provided on the support plate 61.

[0040] Specifically, during stamping, the insulating PC 31 needs to be sampled, and the boss 32 is covered on the inspection table 56, and the insulating PC 31 is located in the inspection slot 55. A T-shaped slot 65 is provided in the support plate 61, and a T-shaped block matching the T-shaped slot 65 is fixedly connected to the measuring plate 62. The height of the boss 32 can be measured by the measuring plate 62 and the scale line 63, and the height of the boss 32 can be quickly detected.

[0041] The height of the detection groove 55 matches the height of the insulating PC 31. Observe whether the insulating PC 31 is flush with the detection groove 55 to detect whether the height of the insulating PC 31 meets the requirements. A limit frame 71 is fixedly connected to the detection fixture 51, and a detection plate 72 is arranged in the limit frame 71. The lower end surface of the detection plate 72 is flush with the upper end surface of the detection groove 55. A detection block 73 is arranged in the detection plate 72, and a second spring 74 is arranged between the detection block 73 and the detection plate 72.

[0042] Push the detection plate 72 forward. If the height of the insulating PC31 is greater than the height of the detection slot 55, the protruding portion of the insulating PC31 will block the detection plate 72, so that the detection plate 72 cannot move forward. If the height of the insulating PC31 is less than the height of the detection slot 55, there is a gap between the detection plate 72 and the insulating PC31, and the detection block 73 can be ejected under the action of the second spring 74. When the detection plate 72 is retracted, the detection block 73 will abut against the side wall of the detection slot 55, so that the detection plate 72 cannot be retracted. When the height of the insulating PC31 is slightly greater than or slightly less than the height of the detection slot 55, it is inconvenient to observe with the naked eye, that is, it is convenient to judge whether the height of the insulating PC31 meets the requirements through the detection plate 72.

[0043] The measuring plate 62 is provided with a detection section 64 that matches the outer diameter of the boss 32. The outer diameter of the boss 32 can be detected to determine whether the outer diameter of the boss 32 meets the requirements.

[0044] A slider 53 is fixedly connected to the detection jig 51, and a slide groove 54 matching the slider 53 is arranged in the storage groove 52. When not in use, the detection jig 51 is conveniently stored in the storage groove 52 to prevent it from being affected by the outside world and thus reducing its accuracy.

[0045] When using, refer to Figure 1 to Figure 5 As shown, the insulating PC31 can be stamped by the embossing equipment. When the insulating PC31 needs to be sampled, the sampled insulating PC31 can be fixed in the detection fixture 51, and the boss 32 can be covered on the detection table 56. The height of the boss 32 can be detected by the measuring plate 62 and the scale line 63, the height of the insulating PC31 can be detected by the detection groove 55, and the outer diameter of the boss 32 can be detected by the detection section 64.

[0046] Compared with the prior art, the utility model provides an insulating PC vertical embossing device, which can quickly detect the size of the insulating PC and the bosses on the insulating PC after embossing the insulating PC, and the sampling operators can operate it after simple training.
