Description

Technical Field

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

[0002] Terminal strips are mainly 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 line, facilitating high-speed data and signal transmission between circuit boards; they are widely used in electronic equipment. After production, terminal strips are collected in reels. When different lengths or quantities of terminals are needed to assemble electronic components, they are punched into terminals of different lengths and specifications using punching equipment. Because terminal strips are made of relatively thin metal workpieces, and the reel-type terminal strips form a certain curved shape when stretched and punched, they need to be shaped before punching.

[0003] Although existing punching mechanisms all have built-in positioning punching functions, there is still a stroke between the reel and the punching mechanism. During this stroke, the terminal strip is at risk of being damaged by the fluctuations generated during punching, resulting in a low yield of punched terminals.

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

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.

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.

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 1-6As shown, this utility model provides a terminal positioning and punching device, which includes a frame 1, a worktable 10 on the frame 1, a terminal conveying mechanism 2 on one side of the worktable 10, and a punching mechanism 4 for punching terminals 14 on the other side; the punching mechanism 4 includes a drive assembly mounted above the worktable 10, an upper cutting die 40 mounted on the drive end of the drive assembly, and a lower cutting die 41 movably mounted on the worktable 10 below the upper cutting die 40; a positioning and conveying mechanism 3 is mounted on the worktable 10 and located between the terminal conveying mechanism 2 and the punching mechanism 4; the positioning and conveying mechanism 3... The system includes a positioning platform 30 mounted on a workbench 10. Two slide rails 301 are provided on one side of the positioning platform 30 along the X-axis. Matching sliders 302 slide on the slide rails 301. A drive plate 303 is mounted on the two sliders 302. A vertically downward transfer cylinder 31 is mounted on the drive plate 303. The telescopic end of the transfer cylinder 31 is equipped with a positioning pin 32 and a positioning block 33. A drive cylinder 35 is driven and connected to the side of the drive plate 303 facing the X-axis. A vertically upward positioning cylinder 34 is mounted below the positioning platform 30. The telescopic end of the positioning cylinder 34 is equipped with a positioning pin 32 and a positioning block 33.

[0039] The present invention provides a terminal positioning and punching device. A terminal conveying mechanism 2 places the free end of a terminal 14 onto a positioning table 30. A transfer cylinder 31 drives a positioning pin 32 and a positioning block 33 on its telescopic end to move downwards. The positioning pin 32 inserts into a positioning hole on the terminal 14 strip, and the positioning block 33 abuts against the terminal 14 strip. A drive cylinder 35 drives the transfer cylinder 31 to move towards the punching mechanism 4, thereby driving the positioning pin 32 to move the terminal 14 towards the punching structure. When the terminal 14 is transferred to the punching station, a positioning cylinder 34 drives the positioning pin 32 and the positioning block 33 on its telescopic end to move upwards. The positioning pin 32 inserts into a positioning hole on the terminal 14 strip, and the positioning block 33 abuts against the terminal 14 strip. At the bottom of the terminal 14 strip, the drive cylinder 35 drives the transfer cylinder 31 to reset, and the positioning pin 32 of the extension end of the transfer cylinder 31 is inserted into the positioning hole of the terminal 14 strip, and the positioning block 33 abuts against the strip; the punching structure punches the terminal 14 below it, thus completing the positioning, conveying and punching operation of the terminal 14; since the positioning pin 32 and positioning block 33 on the positioning cylinder 34 and the transfer cylinder 31 can position the terminal 14 on the positioning table 30; therefore, when the punching mechanism 4 punches the terminal 14, the terminal 14 between the terminal conveying mechanism 2 and the punching mechanism 4 will not be damaged due to its fluctuation; thus improving the yield of the terminal 14 punching.

[0040] Specifically, such as Figure 2-4As shown, a guide base plate 36 is installed on the positioning table 30. Guide pressure strips 37 are respectively provided on both sides of the guide base plate 36 in the X-axis direction. A guide groove 38 is formed between the guide pressure strips 37 and the guide base plate 36. The two free ends of the terminal 14 are respectively inserted into the guide groove 38 for movement; to prevent the terminal 14 from shifting during the transfer process; a positioning slide groove 39 is also provided on the coaxial position of the guide groove 38 below the transfer cylinder 31; when the transfer cylinder 31 drives the positioning pin 32 to move downward, the positioning pin 32 will pass through the positioning hole on the terminal 14 material strip and extend into the positioning slide groove 39; thus, the positioning slide groove 39 provides a guiding function for the positioning pin 32, so that the positioning pin 32, driven by the drive cylinder 35, can transport the terminal 14 along the X-axis direction to the punching station of the punching mechanism 4, further preventing the terminal 14 from being transported off-center.

[0041] Furthermore, such as Figure 5As shown, before punching, in order to flatten the terminal 14 located between the terminal conveying mechanism 2 and the positioning conveying mechanism 3, a shaping mechanism 5 is also provided between the terminal conveying mechanism 2 and the positioning conveying mechanism 3. The shaping mechanism 5 includes an "L"-shaped support frame 50 mounted on the workbench 10. The top of the "L"-shaped support frame 50 is provided with multiple sets of lower guide wheels 51 along the X-axis direction. The number of lower guide wheels 51 can be set according to the thickness of the terminal 14. In this embodiment, the preferred number of lower guide wheels 51 is five sets, with two in each set. The L-shaped support frame 50 is rotatably mounted on both sides of its top end via a pivot. A shaping cylinder 52 is mounted on the base of the L-shaped support frame 50; preferably, the shaping cylinder 52 is a sliding cylinder. The sliding cylinder is vertically mounted on the base of the L-shaped support frame 50. A guide wheel seat 54 is mounted on the slide of the sliding cylinder. Multiple connecting rods 55 slide within the guide wheel seat 54. Multiple U-shaped brackets 56 corresponding to the connecting rods 55 are mounted on the top of the guide wheel seat 54. Adjusting rods 57 are threaded onto the U-shaped brackets 56. The free end of 57 is connected to the top of the connecting rod 55; two upper guide wheels 53 are rotatably mounted on the bottom of the connecting rod 55 via a rotating shaft; the distance between the upper guide wheels 53 and the lower guide wheels 51 can be adjusted by adjusting the rod 57, and the height between multiple sets of upper guide wheels 53 can also be adjusted, so that the multiple sets of upper guide wheels 53 are always on the same plane; this improves the shaping effect of the terminal 14; the upper guide wheels 53 and the lower guide wheels 51 are staggered relative to each other; in the above structure, the terminal 14 passes through the upper guide wheels 53. Between the upper guide wheel 53 and the lower guide wheel 51, the upper guide wheel 53 is driven to move down by the slide cylinder and abut against the terminal 14. At this time, the upper and lower surfaces of the terminal 14 abut against the upper guide wheel 53 and the lower guide wheel 51 respectively. While the positioning and conveying mechanism 3 moves the terminal 14, the terminal 14 slides between the upper guide wheel 53 and the lower guide wheel 51, so that the curved terminal 14 coming out of the turntable 22 of the conveying mechanism can be flattened under the roller pressure of the upper guide wheel 53 and the lower guide wheel 51, further reducing the risk of the terminal 14 breaking.

[0042] Furthermore, in order to correctly guide the terminal 14 between the upper guide wheel 53 and the lower guide wheel 51 for shaping, terminal transition platforms 58 are installed on both sides of the upper end of the "L"-shaped support frame 50. A pressure roller 580 is installed on the terminal transition platform 58 near one end of the terminal conveying mechanism 2. The pressure roller 580 can initially flatten the terminal 14 before it enters the upper guide wheel 53 and the lower guide wheel 51 for shaping, thus improving the shaping effect and efficiency. A displacement sensor 581 is installed on the other terminal transition platform 58. The displacement sensor 581 can provide a signal to the positioning conveying mechanism 3. Through the setting of the background data, the positioning conveying mechanism 3 can punch the terminal 14 conveyed by the punching mechanism 4 at a target distance, thus improving the punching accuracy of the terminal 14.

[0043] In this embodiment, as Figure 6 As shown, the terminal conveying mechanism 2 includes a "7"-shaped bracket 20 mounted on the workbench 10; a rotary motor 21 is mounted on a horizontal bar above the "7"-shaped bracket 20, and a turntable 22 is mounted on the output shaft of the rotary motor 21; terminals 14 are installed in the turntable 22, and the rotary motor 21 drives the turntable 22 to rotate so as to output the terminals 14 in the turntable 22; two guide rods 23 are connected to the horizontal end of the "7"-shaped bracket 20, and a moving block is slidably mounted on the guide rods 23; a rotatable roller 24 is mounted on the moving block, and the roller 24 is arranged in the opening slot of the turntable 22 along the Y-axis direction. By sliding the moving block, the roller 24 can abut or separate from the opening of the turntable 22. When the turntable 22 rotates to release material, the roller 24 can prevent the terminals 14 in the turntable 22 from becoming loose and causing excessive material release.

[0044] Furthermore, such as Figure 1 and Figure 6 As shown, a first guide 11, a second guide 12, and a third guide 13 are sequentially mounted above the workbench 10 along the X-axis. The first guide 11 is inclined and connected to the "7"-shaped bracket 20 and located below the turntable 22. The second guide 12 is horizontally positioned between the first guide 11 and the third guide 13. The third guide 13 is inclined and connected to the terminal transition platform 58 near the terminal conveying mechanism 2. The three guides are arranged in an arc along the X-axis, thereby enabling the terminals 14 conveyed from the turntable 22 to be linearly conveyed toward the shaping mechanism 5.

[0045] 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.
