Description

Technical Field

[0001] This invention relates to the field of workpiece bending technology, and more particularly to a terminal bending device. Background Technology

[0002] With the increasing use of power conversion in industries such as electric vehicles, high-speed rail, and solar energy, the use of IGBT (Insulated Gate Bipolar Transistor) modules in power conversion inverters is growing rapidly. Furthermore, it is frequently necessary to bend the terminals of both 62mm and 34mm IGBT modules. Manually bending terminals is difficult, inaccurate, and costly, making mass production impractical. Existing terminal bending machines can only bend one type of terminal at a time, significantly reducing production efficiency.

[0003] Therefore, there is an urgent need for a terminal bending device to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a terminal bending device that can simultaneously bend multiple module terminals without manual bending, achieving high precision and low cost, thereby improving production efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A terminal bending device, comprising:

[0007] The body includes a base and a cabinet, wherein the cabinet is disposed on the base;

[0008] A slide rail is provided on the base, and one end of the slide rail extends into the cabinet body along a first direction;

[0009] Multiple support mechanisms are provided at intervals along the second direction. The support mechanisms are used to support terminals and are capable of sliding along the extension direction of the slide rail.

[0010] A bending mechanism is disposed inside the cabinet and located above the slide rail. The bending mechanism includes a telescopic component and multiple sets of bending components. The bending components are correspondingly disposed with the supporting mechanism. When the supporting mechanism moves to the lower position of the bending components, the telescopic component can drive the multiple sets of bending components to move downward in the vertical direction and bend the terminals on the multiple supporting mechanisms to a preset shape.

[0011] Preferably, each set of bending components includes at least two bending blocks, which are spaced apart along the first direction. Each bending block has a different bending angle, and the bending angles of the multiple bending blocks increase sequentially along the first direction.

[0012] Preferably, each set of the bending assembly includes three bending blocks, which are capable of bending the terminal to 45°, 75° and 180° respectively in the first direction.

[0013] Preferably, the bearing mechanism is provided with limiting holes, and each bending block is provided with a limiting post. The limiting post can mate with the limiting hole to ensure that the pressing height is the same each time.

[0014] Preferably, the terminal bending device further includes a protective structure, which is used to cover the portion of the base exposed outside the cabinet after the supporting mechanism enters the cabinet.

[0015] Preferably, the protective structure includes a bellows cover, one end of which is disposed on the base. The bellows cover can extend along the first direction. When the supporting mechanism is loading, the bellows cover and the supporting mechanism are attracted and engaged with each other, so that when the supporting mechanism slides along the first direction, it can drive the bellows cover to unfold. After the supporting mechanism enters the cabinet, the bellows cover disengages from the supporting mechanism.

[0016] Preferably, the protective structure further includes a first adsorption member, which is disposed at one end of the bellows cover near the supporting mechanism, so that the bellows cover is adsorbed onto the supporting mechanism. After the supporting mechanism enters the cabinet, the cabinet can limit the bellows cover from continuing to move along the first direction, so that the bellows cover can detach from the supporting mechanism.

[0017] Preferably, the support mechanism includes a support platform and a second adsorption member. The support platform is used to support the terminal, and the second adsorption member is disposed on the side of the support platform near the protective structure. When the support platform is loaded, the first adsorption member and the second adsorption member adsorb each other.

[0018] Preferably, the cabinet is provided with a third adsorption element, and the bellows cover is provided with a fourth adsorption element at both ends along the second direction. After the supporting mechanism enters the cabinet, the third adsorption element is adsorbed onto the fourth adsorption element.

[0019] Preferably, the cabinet is also equipped with an operation screen.

[0020] The beneficial effects of this invention are:

[0021] This invention discloses a terminal bending device. The terminal bending device includes a body, a slide rail, a supporting mechanism, and a bending mechanism. The body includes a base and a cabinet, with the cabinet mounted on the base. The slide rail is mounted on the base, with one end extending into the cabinet along a first direction. Multiple supporting mechanisms are spaced apart along a second direction, and these supporting mechanisms are used to support terminals and can slide along the extension direction of the slide rail. The bending mechanism is located inside the cabinet and above the slide rail. The bending mechanism includes a telescopic component and multiple sets of bending assemblies. The bending assemblies are correspondingly arranged with the supporting mechanisms. When the supporting mechanism moves below the bending assemblies, the telescopic component can drive the multiple sets of bending assemblies to move downwards vertically and bend the terminals on the multiple supporting mechanisms to a preset shape.

[0022] In this equipment, each supporting mechanism can support a terminal of a specific device, and the supporting mechanism can slide along a slide rail into the cabinet. This allows multiple sets of bending components to descend via telescopic parts, enabling the simultaneous bending of various terminals without manual bending. This not only ensures high precision and low cost but also improves production efficiency. Furthermore, the bending mechanism is located inside the cabinet during bending operations, preventing structural exposure and guaranteeing good operational safety. Attached Figure Description

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 4As shown, the present invention provides a terminal bending device, which includes a body 10, a slide rail 20, a supporting mechanism 30, and a bending mechanism 40. The body 10 includes a base 11 and a cabinet 12, with the cabinet 12 disposed on the base 11. The slide rail 20 is disposed on the base 11, with one end of the slide rail 20 extending into the cabinet 12 along a first direction. Multiple supporting mechanisms 30 are spaced apart along a second direction, and the supporting mechanisms 30 are used to support terminals and can slide along the extension direction of the slide rail 20. The bending mechanism 40 is disposed inside the cabinet 12 and above the slide rail 20. The bending mechanism 40 includes a telescopic member 41 and multiple sets of bending components. The bending components are correspondingly disposed with the supporting mechanisms 30. When the supporting mechanism 30 moves to below the bending components, the telescopic member 41 can drive the multiple sets of bending components to move downward in the vertical direction and bend the terminals on the multiple supporting mechanisms 30 to a preset shape.

[0039] In this device, each supporting mechanism 30 can support a terminal of a specific device, and the supporting mechanism 30 can slide on the slide rail 20 into the cabinet 12. This allows the telescopic component 41 to drive multiple sets of bending assemblies downwards, enabling simultaneous bending of multiple terminals without manual bending. This not only achieves high precision and low cost but also improves production efficiency. Furthermore, the bending mechanism 40 is located inside the cabinet 12 during bending operations, preventing structural exposure and ensuring good operational safety.

[0040] It should be noted that in this embodiment, the telescopic component 41 is a cylinder. Cylinders are not only simple in structure and inexpensive, but also easy to install and use, reducing manufacturing and operating costs. Furthermore, the device includes a drive component capable of moving the carrying mechanism 30. During loading, the carrying mechanism 30 is located outside the cabinet 12. After loading is complete, the drive component can move the carrying mechanism 30 into the cabinet 12 to perform the bending operation, thereby improving automation and reducing manual intervention. In this embodiment, two carrying mechanisms 30 are provided, meaning that two carrying mechanisms 30 can simultaneously carry different types of terminals into the cabinet 12, thus completing the bending of two types of terminals simultaneously. In other embodiments, the number of carrying mechanisms 30 can be adjusted according to requirements.

[0041] In addition, an operation screen 14 is installed on the cabinet 12. Workers can operate according to the prompts on the operation screen 14 to complete continuous transportation and bending work.

[0042] Specifically, such as Figures 1-3As shown, each bending assembly includes at least two bending blocks 42, which are spaced apart along a first direction. Each bending block 42 has a different bending angle, and the bending angles of the multiple bending blocks 42 increase sequentially along the first direction. This arrangement allows for multiple bending of the terminals, with only a partial bend completed each time, thus avoiding poor bending results in a single operation, ensuring good bending performance, and improving yield.

[0043] In this embodiment, each bending assembly includes three bending blocks 42. In the first direction, the three bending blocks 42 can bend the terminal to 45°, 75°, and flattened states, respectively. That is, after the supporting mechanism 30 moves the terminal to the first bending block 42, the telescopic member 41 can drive the first bending block 42 to press down and bend the terminal into a 45° opening. At this time, the supporting mechanism 30 continues to move along the first direction, the second bending block 42 presses down and bends the terminal into a 75° opening, the supporting mechanism 30 continues to move along the first direction, and the third bending block 42 presses down and completely flattens the terminal, thereby completing the entire bending operation. During this process, the bending operation is gradual, and the bending angle is always within a controllable range, thereby avoiding the situation where the terminal breaks due to a one-time bending.

[0044] It is worth noting that in other embodiments, more bending blocks 42 can be provided, as long as the bending angle of the bending blocks 42 increases sequentially along the first direction.

[0045] Furthermore, it should be noted that in this embodiment, the bending blocks 42 at different angles are used to bend the shapes of the terminals, so even if they are pressed down to the same height, the bending angles can be different. However, to ensure that the bending blocks 42 at different angles can all be pressed down to the same height, such as... Figure 2 As shown, the bearing mechanism 30 is provided with limiting holes, and each bending block 42 is provided with a limiting post 43. The limiting post 43 can align with the limiting hole to ensure that the pressing height is the same each time. That is, during the bending operation, the limiting post 43 can move simultaneously with the bending block 42. When the limiting post 43 aligns with the limiting hole, it indicates that the bending block 42 has reached the preset height, at which point the terminal can be bent to the preset angle (45°, 75°, or flattened state), thus ensuring the accuracy of the bending angle. In addition, by setting the limiting post 43, it is also possible to avoid the terminal breaking due to excessive pressing, thereby ensuring the yield and service life of the terminal.

[0046] like Figures 1-4As shown, the terminal equipment also includes a protective structure 50. After the supporting mechanism 30 enters the cabinet 12, the protective structure 50 is used to cover the part of the base 11 exposed outside the cabinet 12. This arrangement not only prevents dust from entering the cabinet 12, but also covers the entrance of the cabinet 12, preventing operators from accidentally touching or putting their hands into the cabinet 12, thus improving the safety of use.

[0047] Specifically, such as Figures 1-4 As shown, the protective structure 50 includes a bellows cover 51, one end of which is mounted on the base 11. The bellows cover 51 can extend along a first direction. When the supporting mechanism 30 loads materials, the bellows cover 51 and the supporting mechanism 30 adhere to each other, so that when the supporting mechanism 30 slides along the first direction, it can drive the bellows cover 51 to unfold. After the supporting mechanism 30 enters the cabinet 12, the bellows cover 51 disengages from the supporting mechanism 30. That is, the supporting mechanism 30 can load materials into the cabinet 12. Due to the mutual adhesion between the supporting mechanism 30 and the bellows cover 51, as the supporting mechanism 30 moves into the cabinet 12, it can drive the bellows cover 51 to gradually unfold until the supporting mechanism 30 is completely inside the cabinet 12. At this time, the bellows cover 51 will be stopped and limited by the cabinet 12. As the supporting mechanism 30 continues to move, the bellows cover 51 will disengage from the supporting mechanism 30, thereby completing the sealing of the exterior of the cabinet 12 without affecting subsequent bending work.

[0048] like Figures 1-4 As shown, the protective structure 50 also includes a first adsorption member 52, which is disposed at the end of the bellows cover 51 near the supporting mechanism 30, so that the bellows cover 51 is adsorbed onto the supporting mechanism 30. After the supporting mechanism 30 enters the cabinet 12, the cabinet 12 can limit the bellows cover 51 from continuing to move in the first direction, so that the bellows cover 51 can detach from the supporting mechanism 30. This arrangement is not only simple in structure, but also convenient to install, requiring only the first adsorption member 52 to be correspondingly installed on the bellows cover 51, reducing manufacturing costs and improving ease of use.

[0049] In addition, such as Figures 1-4 As shown, the supporting mechanism 30 includes a supporting platform 31 and a second adsorption member 32. The supporting platform 31 is used to support the terminals, and the second adsorption member 32 is disposed on the side of the supporting platform 31 near the protective structure 50. When the supporting platform 31 is loaded, the first adsorption member 52 and the second adsorption member 32 adsorb each other. This arrangement can further improve the stability of the adsorption between the supporting platform 31 and the bellows cover 51, ensuring sufficient adsorption force, thereby preventing the bellows cover 51 from detaching from the supporting platform 31 before the supporting mechanism 30 is fully immersed in the cabinet 12.

[0050] like Figures 1-4As shown, a third suction element 13 is provided on the cabinet 12, and a fourth suction element 53 is provided at both ends of the bellows cover 51 along the second direction. After the supporting mechanism 30 enters the cabinet 12, the third suction element 13 is attracted to the fourth suction element 53. That is, after the supporting platform 31 enters the cabinet 12, the bellows cover 51 detaches from the supporting platform 31. At this time, the third suction element 13 and the fourth suction element 53 attract and cooperate with each other, thereby preventing the bellows cover 51 from springing back to its initial position, thus ensuring that the bellows cover 51 always covers the entrance of the cabinet 12 and ensuring the safety of the operation.

[0051] It should be noted that the first adsorption component 52, the second adsorption component 32, the third adsorption component 13, and the fourth adsorption component 53 are all magnets. Magnets are not only simple in structure but also easy to install. They can be attached to each other by simply bringing them close together. Even after the support platform 31 enters the cabinet 12, they can also improve the ease of detachment between the support platform 31 and the bellows cover 51, ensuring good performance.

[0052] The working process of the terminal bending equipment in this embodiment is explained with reference to the accompanying drawings:

[0053] First, the support platform 31 is located outside the cabinet 12 for loading. At this time, the bellows cover 51 is in a compressed state, and the first adsorption component 52 and the second adsorption component 32 adsorb each other.

[0054] Secondly, the support platform 31 slides along the slide rail 20, and the support platform 31 drives the bellows cover 51 to unfold. When it is fully immersed in the cabinet 12, the first adsorption component 52 and the second adsorption component 32 separate, and the bellows cover 51 fully unfolds to cover the entrance of the cabinet 12. The third adsorption component 13 and the fourth adsorption component 53 adsorb each other to prevent the bellows cover 51 from rebounding.

[0055] Finally, as the two support platforms 31 move continuously, the two types of terminals are bent at 45° and 75° in sequence until they are completely flattened to obtain the target product.

[0056] In summary, this equipment can simultaneously bend multiple module terminals without manual bending, offering high precision, low cost, and high efficiency. Furthermore, it prevents dust and operator arms from entering the cabinet 12, ensuring operational safety.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
