Description

Technical Field

[0001] This utility model relates to the field of punching equipment technology, specifically to a displaceable terminal positioning punching device. Background Technology

[0002] Terminal strips are primarily used in electronic connections, automated production, automotive wiring harnesses, and industrial control. By connecting electronic components together, terminal strips provide efficient data transmission and power supply; they utilize strip material to connect electronic components into a single line, facilitating high-speed data and signal transmission between circuit boards; and are widely used in electronic devices. After production, terminal strips are collected in reels. When different lengths or quantities of terminals are needed to assemble electronic components, they are cut into terminals of different lengths and specifications using punching equipment.

[0003] In the terminal punching process, the terminal is first placed on the lower die of the punching mechanism. The upper die is then driven by a drive device to move relative to the lower die, thereby punching the terminal into the target specification. After the terminal is punched, it needs to be removed to facilitate the next punching operation. However, the lower die of the existing terminal punching mechanism is placed manually on the workstation below the upper die. Due to the limited space between the upper and lower dies, it is not suitable for a robot to pick up the terminal from the lower die. Therefore, after the terminal is punched, it is still necessary to manually remove the punched terminal from the lower die. This poses a safety hazard and reduces the efficiency of terminal punching due to manual operation.

[0004] Therefore, there is an urgent need for a displaceable terminal positioning and punching device to solve the above problems. Utility Model Content

[0017] As an optional technical solution for a displaceable terminal positioning and punching device, a limiting plate is provided between the drive plate and the lower cutting die.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0038] like Figure 1-6 As shown, this utility model provides a displaceable terminal positioning and punching device, which includes: a worktable 1, on which a punching mechanism 2 and a guide table for guiding and conveying terminals are mounted on the worktable 1 along the same axis; the punching mechanism 2 includes a slide rail 20 mounted on the worktable 1, on which a matching slider 201 slides; a drive plate 21 is mounted on the slider 201, and a lower cutting die 22 is mounted on the top of the drive plate 21; a... There is a rodless cylinder 24, the moving end of which is connected to the drive plate 21; guide columns 25 are respectively installed on the worktables 1 on the left and right sides of the slide rail 20, and a punching cylinder 26 is mounted on the top of the guide column 25. The telescopic end of the punching cylinder 26 is connected to the upper cutting die 27, which is slidably mounted on the guide column 25. The upper cutting die 27 is equipped with a cutter 270 and a positioning component 28 for terminal positioning at the end of the upper cutting die 27 near the guide table; the upper and lower dies and the lower cutting die 22 are arranged opposite each other.

[0039] The present invention provides a displaceable terminal positioning and punching device. An external terminal conveying mechanism transports the free end of a terminal along a guide table to the lower cutting die 22. A punching cylinder 26 drives an upper cutting die 27 to cause a cutter 270 and a positioning component 28 to move downwards. At this time, a positioning block 284 on the positioning component 28 presses against the terminal on the guide plate 31 near the lower cutting die 22. Simultaneously, the cutter 270 performs a relative punching motion on one side of the lower cutting die 22 and cuts off the terminal, thus completing the terminal positioning and punching operation. Since the lower cutting die 22 is slidably mounted on a slide rail 20 via a drive plate 21, after the terminal punching operation is completed, the lower cutting die 22 and the terminal located on it are moved out from below the upper cutting die 27 under the drive of a rodless cylinder 24. Finally, an external robotic arm removes the punched terminal from the lower cutting die 22. This displaceable terminal positioning and punching device prevents safety hazards caused by manual operation and improves terminal punching efficiency.

[0040] Specifically, such as Figure 2As shown, the guide table includes two support plates set on the workbench 1, and a bearing plate guide table 30 is installed on the top of the two support plates; a guide plate 31 is stacked on the bearing plate guide table 30, and guide pressure strips 32 are respectively installed on both sides of the guide plate 31 along the X-axis direction. A guide groove 33 is formed between the guide pressure strips 32 and the guide plate 31. The free end of the terminal is moved from the external conveying mechanism to the guide plate 31 and passes through the guide groove 33, and finally moved to the lower cutting die 22. This structure prevents the terminal from shifting position during the transfer process.

[0041] In this embodiment, as Figure 1 As shown, four guide pillars 25 are provided and are vertically installed on the worktable 1 and located on both sides of the slide rail 20. A top plate 251 is installed on the top of the four guide pillars 25. The punching cylinder 26 is vertically downward installed on the top plate 251. Linear bearings are slidably installed on the four guide pillars 25 respectively. A movable plate 261 is connected between the four linear bearings. The telescopic end of the punching cylinder 26 is connected to the top of the movable plate 261. The upper cutting die 27 is installed at the bottom of the movable plate 261. The punching cylinder 26 drives the movable plate 261 to drive the upper cutting die 27 to move up and down. The arrangement of the four guide pillars 25 not only provides guidance for the movable plate 261, but also enables the upper cutting die 27 to move up and down more stably, improving the accuracy of terminal punching.

[0042] Furthermore, such as Figure 3 and Figure 4 As shown, a support frame 262 connects the movable plate 261 and the upper cutting die 27. An upper limit cylinder 263 is mounted on the bottom surface of the support frame 262. A limit seat 264 is slidably mounted on the top surface of the upper cutting die 27 via multiple guide rods. Multiple upper limit rods 265 are connected to the bottom of the limit seat 264, and the ends of the upper limit rods 265 are Y-shaped. The top of the limit seat 264 is connected to the telescopic end of the upper limit cylinder 263. The free ends of the upper limit rods 265 pass through the upper cutting die and extend below it. The upper limit cylinder 263 drives... The moving limit base drives multiple upper limit rods 265 to extend and retract at the bottom of the upper cutting die 27; the cutter 270 is embedded on one side of the upper cutting die 27; in this structure, before the punching cylinder 26 drives the upper cutting die 27 to move downward to punch the terminal, the upper limit cylinder 263 drives the upper limit seat 264 and drives the upper limit rods 265 to pass through the upper cutting die 27 and extend to the bottom of the upper cutting die 27 to limit and fix the terminal, so that the terminal is more stable during the punching process and prevents the terminal from shifting during punching, which would lead to inaccurate punching accuracy.

[0043] In this embodiment, as Figure 3 and Figure 5As shown; a limiting plate 23 is provided between the drive plate 21 and the lower cutting die. Multiple lower limiting rods 211 are installed on the upper surface of the limiting plate 23, and the ends of the lower limiting rods 211 are Y-shaped. The free ends of the lower limiting rods 211 pass through the lower cutting die 22 and extend to the upper surface of the lower cutting die 22. Second guide rods 215 are installed at the four corners of the lower cutting die 22, and the bottom ends of the second guide rods 215 pass through the limiting plate 23 and are connected to the drive plate 21. A lifting cylinder 212 is provided at the bottom of the drive plate 21, and the telescopic end of the lifting cylinder 212 passes through the drive plate 21 and is connected to the limiting plate 21. At the bottom of the position plate 23, when the lifting cylinder 212 drives the limiting plate 23 to slide up and down on the second guide rod 215, the lower limiting rod 211 will pass through the lower cutting die 22 and perform telescopic movement. As a result, when the part of the terminal that needs to be punched moves onto the lower cutting die 22, the lifting cylinder 212 will drive the lower limiting rod 211 to pass through the lower cutting die 22 and limit the terminal, while the upper limiting cylinder 263 will drive the upper limiting rod 265 to move down and limit the terminal through the free end of the upper limiting rod 265 and the free end of the lower limiting rod 211, thereby improving the stability of the terminal punching.

[0044] Furthermore, the upper cutting die 27 is fixedly connected to the bottom of the support frame 262, and the four corners of the upper cutting die 27 are respectively equipped with first guide rods 213; the four corners of the limiting plate 23 are respectively equipped with sliding sleeves 214; when the upper cutting die 27 moves downward, it is inserted into the sliding sleeves 214 through the first guide rods 213, which improves the accuracy and stability of die closing and punching between the upper cutting die 27 and the lower cutting die 22.

[0045] In this embodiment, as Figure 3 As shown, the rodless cylinder 24 is mounted on the worktable 1 on one side of the slide rail 20 along the X-axis. The moving end of the rodless cylinder 24 is connected to the drive plate 21. After the terminal is punched, the rodless cylinder 24 drives the drive plate 21 to move the lower cutting die 22 and the terminal outward. Due to the setting of the lifting cylinder 212 and the lower limit rod 211, the terminal can be lifted upward, thus facilitating the external robot to grasp the terminal, improving the punching efficiency of the terminal, and avoiding the need for manual operation on the upper cutting die 21. Safety hazards arising from terminal gripping between 7 and the lower cutting die 22; furthermore, support blocks 10 are installed at both ends of the slide rail 20, and limit sensors 11 are provided on the support blocks 10. The limit sensors 11 can accurately control the movement of the rodless cylinder 24 driving the lower cutting die 22; on the other hand, the support blocks 10 are also provided with limit screws 12, which are threaded to the support blocks 10. That is to say, the limit screws 12 can physically limit the lower cutting die 22.

[0046] In this embodiment, as Figure 6As shown, the positioning assembly 28 includes a positioning base 280 disposed on the upper cutting die 27 and near the guide plate 31. A positioning upper seat 281 is mounted on the positioning base 280, and a cavity 282 is provided at the bottom of the positioning upper seat 281. A positioning rod 283 is inserted through the positioning base 280 located below the cavity 282, and a retaining ring is provided at the top of the positioning rod 283. A positioning block 284 is connected to the free end of the positioning rod 283 located below the positioning base 280. A mounting hole 286 is provided at the top of the cavity 282. The 6 is equipped with a spring 285 or an elastic airbag; the top end of the positioning rod 283 abuts against the bottom end of the spring 285, and the top end of the positioning upper seat 281 is also equipped with a baffle 287. The baffle 287 blocks the top of the mounting hole 286 and abuts against the top end of the spring 285. When the cutting die 22 moves downward, the positioning block 284 abuts against the terminal on the guide plate 31. Under the compression of the spring 285, the positioning block 284 will provide a certain pressure to press the terminal, so that the terminal is displaced during punching, which improves the stability of terminal punching.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
