Description

Technical Field

[0001] This invention relates to the field of terminal processing equipment technology, and more specifically to a terminal strip cutting device. Background Technology

[0002] In the manufacturing of electronic components, connectors, and various precision electrical parts, terminals are typically formed in a continuous arrangement on a strip of carrier material, creating a "terminal strip." Before use, these connected individual terminals need to be precisely separated from the strip. This separation process is mainly accomplished by a cutting device, the core of which is to cut off the small parts connecting the terminals to the carrier strip.

[0003] Traditional terminal strip cutting methods mostly rely on manual operation or semi-automatic equipment. Manual operation is not only inefficient and labor-intensive, but semi-automatic cutting equipment also uses simple gears or friction wheels for feeding. For terminal strips with precision positioning holes, it is difficult to achieve accurate positioning for each feed. Moreover, the strip is in an unrestrained state during movement, which can easily cause overshoot or inaccurate positioning due to inertia or transmission errors. In addition, the strip often lacks effective guidance and restraint during transport, further increasing positional uncertainty. In the cutting stage, most equipment relies on a single positioning structure downstream of the cutting point for fixation. For strips with a certain degree of flexibility, the upstream part is prone to local movement or slight warping due to stress impact during the punching moment, resulting in cutting position deviation and affecting cutting accuracy. Therefore, we propose a terminal strip cutting device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a terminal strip cutting device that overcomes the deficiencies of existing technologies. It features a reasonable design and compact structure, solving the problems of low cutting efficiency in manual terminal strip cutting and low cutting accuracy in semi-automatic cutting equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a terminal strip cutting device, comprising a base, wherein the top of the base is provided with a feeding mechanism, a guiding mechanism and a cutting mechanism;

[0006] The material guiding mechanism is used to guide and laterally limit the terminal strip during the conveying process;

[0007] The feeding mechanism is located on one side of the guiding mechanism and is used to pull the terminal strip for intermittent step-by-step conveying.

[0008] The cutting mechanism is located at the end of the guiding mechanism along the material feeding direction and is used to punch the terminal strip conveyed to the designated position.

[0009] The cutting mechanism includes:

[0010] A cutting platform, which is fixed to the base;

[0011] A cutting cylinder is mounted above the cutting platform via a column and a fixing block;

[0012] A cutting plate, which is connected to the output end of the cutting cylinder;

[0013] A pair of cutters and at least six positioning pins are mounted on the bottom of the cutting plate. The positioning pins are distributed on both sides of the cutters and are used to insert into the positioning holes at the front, back and middle of the terminal strip at the corresponding positions of the cutters.

[0014] Preferably, the top of the cutting platform is provided with two rows of first guide rollers equidistantly arranged along the material feeding direction. The middle of the first guide rollers has a tapered structure for limiting the side wall of the terminal strip. The top of the cutting platform is provided with a pin hole corresponding to the position of the positioning pin, and a support block offset from the cutter for supporting the bottom of the terminal strip. The base and the cutting platform are provided with a discharge port corresponding to the cutter position for the terminals after the terminal strip is cut to pass through.

[0015] Preferably, a pressure plate is laid flat on the top of the first guide wheel, and a cutting channel for the cutting plate to pass through is opened in the pressure plate and the fixing block.

[0016] Preferably, the feeding mechanism includes:

[0017] The first guide rail is fixed on the base and arranged along the material conveying direction;

[0018] The movable frame is slidably connected to the first guide rail;

[0019] A lifting frame, which is slidably connected to the movable frame in the vertical direction;

[0020] The positioning frame is located below the lifting frame;

[0021] A pair of feed pins are mounted on the positioning frame, and the spacing between them is adapted to the spacing between the positioning holes on both sides of the terminal strip.

[0022] A positioning unit is used to drive the lifting frame to perform lifting movements so that the feed pin can be inserted into or disengaged from the positioning hole of the terminal strip;

[0023] The feeding unit is used to drive the movable frame to reciprocate linearly along the first guide rail.

[0024] Preferably, the positioning unit includes:

[0025] A positioning cylinder is mounted on the movable frame;

[0026] A positioning block is connected to the output end of the positioning cylinder and is constrained to slide in the horizontal direction. The positioning block is provided with an inclined positioning groove.

[0027] A protruding column, which is fixed on the lifting frame and has one end extending into the positioning groove;

[0028] When the positioning cylinder drives the positioning block to move horizontally, the movement is converted into the lifting motion of the lifting frame through the cooperation of the positioning groove and the protruding post.

[0029] Preferably, the feeding unit includes:

[0030] A feed motor, which is fixed on the base;

[0031] A cam, which is mounted on the output shaft of the feed motor;

[0032] A connecting rod, one end of which is eccentrically rotatably connected to the cam;

[0033] A push-pull block, which is rotatably connected to the other end of the connecting rod;

[0034] The connecting block is connected at the top to the movable frame and slidably connected at the bottom to the second guide rail fixed to the base.

[0035] Preferably, the push-pull block has an inverted U-shaped structure and is fitted onto the U-shaped connecting block, and the length of the U-shaped structure of the connecting block is greater than the length of the push-pull block, so as to leave a gap time for the lifting frame to rise and fall when the push-pull block reciprocates to push the connecting block. The connecting block has a guide rod that passes through the connecting block inside the U-shaped structure.

[0036] Preferably, the lifting frame is a frame structure, and the movable block has a vertical groove for the lifting frame to slide. The front side of the movable block has a horizontal groove for the positioning block to slide laterally. The vertical groove and the horizontal groove are connected to facilitate the insertion of the protruding column into the positioning groove.

[0037] Preferably, the material guiding mechanism includes a material guiding plate, which is fixed to the base;

[0038] The second guide rollers are arranged in a row on the top of the guide plate, and the middle of the second guide rollers has a tapered structure for limiting the side wall of the terminal strip.

[0039] A strip groove is formed at the top of the guide plate and provides a moving channel for the feed pin of the feeding mechanism.

[0040] Preferably, a limiting mechanism is provided at the top of the base at the end of the cutting mechanism. The limiting mechanism includes a support frame and a pair of limiting plates disposed on its top. A limiting gap is formed between the limiting plates and the support frame to allow the cut strip to pass through.

[0041] This invention provides a terminal strip cutting device. It has the following advantages:

[0042] 1. By setting up a feeding mechanism, a guiding mechanism, and a cutting mechanism, the entire process from material belt feeding, step conveying, precise positioning to punching and separation is fully automated, which significantly improves production efficiency and reduces reliance on manual operation.

[0043] 2. Before cutting, six positioning pins are first inserted into multiple positioning holes of the strip to achieve precise positioning and clamping of the strip, effectively eliminating cutting errors caused by strip movement or deformation. The support block on the cutting platform provides support to the bottom of the strip near the cutting point, and together with the pressure plate at the top, prevents the strip from warping, further ensuring the stability of the strip during the cutting process and reducing errors.

[0044] 3. The feeding mechanism adopts a mechanical linkage method of "lifting insertion - horizontal pulling and feeding - lifting and resetting". The lifting and lowering of the feeding pin is controlled by the inclined groove mechanism driven by the positioning cylinder to ensure that the pin can be accurately inserted into the positioning hole of the material strip. The feeding motor drives the feeding component to move horizontally through the cam linkage mechanism with stable step distance. This mechanical linkage ensures the timing coordination and positioning accuracy of the feeding action.

[0045] 4. In the feeding unit, the U-shaped structure of the connecting block is longer than the push-pull block, creating a mechanical "time window". This allows the horizontal reciprocating motion of the feeding component and the lifting action of the feeding pin to be seamlessly connected under the continuous operation of the motor. There is no need to frequently start and stop the motor for the lifting action, which simplifies the control logic, saves power consumption, and improves the equipment operating cycle and production efficiency.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] See attached document Figure 1-10 A terminal strip cutting device includes a base 1, and a feeding mechanism, a guiding mechanism and a cutting mechanism are provided on the top of the base 1.

[0059] The feeding mechanism is located on one side of the guiding mechanism and is used to guide the intermittent conveying of the material strip at the top terminal of the guiding mechanism;

[0060] The cutting mechanism is located at the end of the guiding mechanism along the material feeding direction. It is used to punch the terminal strip conveyed to the designated position to separate individual terminals.

[0061] The cutting mechanism includes a cutting platform 41 fixed on a base 1. The top of the cutting platform 41 is provided with several rectangular columns 42. A fixing block 43 is installed on the top of these columns 42. A cutting cylinder 44 is provided on the top of the fixing block 43. The output end of the cutting cylinder 44 is vertically downward and connected to a cutting plate 45. At the bottom of the cutting plate 45, there is a pair of cutters 46 for cutting the material strip and the terminal connection position and six positioning pins 47. The six positioning pins 47 are arranged in two rows and three columns in a rectangle on both sides of the cutter 46. Their positions correspond one-to-one with the preset positioning holes on the terminal material strip. They are used to insert into the positioning holes before cutting to achieve precise positioning of the cutting position.

[0062] The top of the cutting platform 41 is provided with two rows of first guide rollers 411 equidistantly arranged along the terminal strip conveying direction. The middle part has a tapered structure for guiding the terminal strip conveying and limiting its side wall. The top of the cutting platform 41 is also provided with corresponding pin holes 412 for the insertion of positioning pins 47. The top of the cutting platform 41 is provided with several support blocks 413. These support blocks 413 are offset from the blade of the cutter 46 and are used to support the terminal strip from the bottom during cutting to ensure stable cutting. On the base 1 and the cutting platform 41, there are feeding ports 414 at the position directly below the cutter 46. The cut single terminal falls through this port and enters the collection box. The collection box is prior art and is not specifically shown in the figure.

[0063] To prevent the material strip from warping in the cutting area and affecting accuracy, a pressure plate 48 is laid flat on top of the first guide wheel 411. The pressure plate 48 and the fixing block 43 are both vertically opened with cutting channels 49 for the cutting plate 45 and its cutting blade 46 and positioning pin 47 to pass through.

[0064] The feeding mechanism includes a first guide rail 21, a movable frame 22, a movable block 23, a lifting frame 24, a positioning frame 25, a pair of feeding pins 26, a positioning unit, and a feeding unit;

[0065] The first guide rail 21 is fixedly installed on the base 1, and its extension direction is arranged along the conveying direction of the material belt. The movable frame 22 is slidably connected to the top of the first guide rail 21 and can slide back and forth on it. The movable block 23 is fixed on one side of the movable frame 22. The movable block 23 has a vertical groove 231 in its interior and a horizontal sliding groove 232 on its front side, and the vertical groove 231 and the horizontal sliding groove 232 are interconnected.

[0066] The lifting frame 24 is a frame structure, and one side wall of it is slidably connected to the vertical groove 231 of the movable block 23, so that the lifting frame 24 can slide up and down relative to the movable block 23. The bottom of the lifting frame 24 is provided with a positioning frame 25, and the positioning frame 25 is provided with a pair of feeding pins 26. The two feeding pins 26 are installed vertically, and the distance between the two feeding pins 26 is indirectly adapted to the positioning holes on both sides of the terminal strip to be processed, so that the feeding pins 26 can be inserted into the positioning holes when they move downward.

[0067] The positioning unit is used to control the lifting frame 24 to move up and down. The positioning unit includes a positioning cylinder 271 installed on the movable frame 22. The output end of the positioning cylinder 271 is connected to a positioning block 272. The positioning block 272 is slidably set in the transverse groove 232 of the movable block 23. An inclined positioning groove 273 is opened in the positioning block 272. A protruding post 241 is fixed on the lifting frame 24. One end of the protruding post 241 extends into the positioning groove 273. When the positioning cylinder 271 works, it drives the positioning block 272 to move horizontally. At this time, under the action of the inclined surface of the positioning groove 273, the protruding post 241 is forced to drive the lifting frame 24 to move up and down in the vertical groove 231, thereby realizing the insertion and disengagement of the feed pin 26 and the material belt positioning.

[0068] The feeding unit drives the movable frame 22, together with the positioning unit thereon, to reciprocate along the first guide rail 21 to pull the material belt forward. The feeding unit includes a feeding motor 281 fixed on the base 1. A cam 282 is mounted on the output shaft of the feeding motor 281. The cam 282 is eccentrically connected to a connecting rod 283 via a pin. The end of the connecting rod 283 away from the cam 282 is rotatably connected to a push-pull block 284 via a pin. The push-pull block 284 has an inverted U-shaped structure. The bottom of the push-pull block 284 is provided with a U-shaped connecting block 285. The push-pull block 284 is fitted inside the U-shaped structure of the connecting block 285. The top of the connecting block 285... Connected to the movable frame 22, the bottom is slidably connected to the second guide rail 286 fixed on the base 1. The guide direction of the second guide rail 286 is set along the conveying direction of the material belt. In addition, the U-shaped structure of the connecting block 285 is provided with a guide rod 287 that passes through the connecting block 285 to increase the stability of the movement. In particular, the length of the U-shaped structure of the connecting block 285 is greater than the length of the push-pull block 284, so that when the push-pull block 284 is driven by the connecting rod 283 to make reciprocating motion, there is a time difference between its contact and push with the connecting block 285, which leaves a necessary gap time for the lifting frame 24 to lift at the end of the stroke, without having to stop and wait.

[0069] The guiding mechanism includes a guide plate 31 fixed on the base 1. Two rows of second guide rollers 32 are equidistantly arranged on the top of the guide plate 31 along the conveying direction of the material strip. Each second guide roller 32 has a tapered structure in the middle. This structure can be used to guide the conveying of the terminal material strip and limit the side of the terminal material strip to prevent it from deviating, thereby ensuring the straightness of the conveying. A pair of strip grooves 33 that cooperate with the feed pin 26 are opened on the top of the guide plate 31. The strip grooves 33 are arranged along the conveying direction of the terminal material strip, and their length is greater than the single lateral movement distance of the feed pin 26, providing a channel for the displacement of the feed pin 26 after it is inserted into the positioning hole of the terminal material strip, thus avoiding interference.

[0070] At the top of the base 1, a limiting mechanism is provided at the end of the cutting mechanism. The limiting mechanism includes a support frame 51. A pair of opposing limiting plates 52 are provided on the top of the support frame 51. A gap is left between the limiting plates 52 and the support frame 51 for the passage of the feeding belt. This gap can limit the upper and lower surfaces of the cut material belt to prevent it from sagging or tilting due to its own weight or inertia, and ensure that the material belt is output smoothly.

[0071] Working principle: In the initial state, the feed pin 26 of the feeding mechanism is in the raised state. During operation, the positioning cylinder 271 is activated, driving the lifting frame 24 to descend through the cooperation of the positioning inclined groove 273 and the protrusion 241, so that the feed pin 26 is inserted into the positioning hole of the terminal strip placed in the initial position. Subsequently, the feeding motor 281 starts, driving the connecting block 285 and the movable frame 22 to move forward one step along the guide rail through the cam 282, connecting rod 283, and push-pull block 284, thereby pulling the strip forward. After each step is completed, the positioning cylinder 271 reverses its action, causing the feed pin 26 to lift and disengage from the material belt positioning hole. Since the length of the U-shaped structure of the connecting block 285 is greater than the length of the push-pull block 284, when the push-pull block 284 is driven by the connecting rod 283 to reciprocate, there is a time difference in the contact and push between it and the connecting block 285. During this process, the feed motor 281 does not need to stop and can maintain continuous operation. Immediately afterwards, the feed motor 281 will drive the movable frame 22 to reset, ready for the next feeding cycle.

[0072] The pulled material strip is guided by the second guide wheel 32 of the guiding mechanism and enters the cutting mechanism area. It is then guided forward by the first guide wheel 411. When the cutting station on the material strip reaches directly below the cutter 46, the cutting cylinder 44 drives the cutting plate 45 to move downward. First, six positioning pins 47 are inserted into the positioning holes of the material strip to complete the precise positioning. Then, a pair of cutters 46 move downward and cut the material strip under the support of the support block 413 to obtain a single terminal. The terminal falls from the discharge port 414. The cut waste material strip continues to move forward and passes through the gap between the support frame 51 and the limiting plate 52. This cycle is repeated to achieve automatic, precise and continuous cutting of the terminal material strip.
