Description

Technical Field

[0001] This utility model relates to the field of terminal processing equipment technology, specifically to a feeding mechanism for processing terminal strips. Background Technology

[0002] In the field of electronic component manufacturing, terminals are typically processed in the form of continuous strips through stamping, forming, and injection molding. During processing, the strip needs to be fed precisely and intermittently into the processing station. Traditional feeding mechanisms usually employ a cyclical action of "clamping-forward-releasing-resetting." The drive mechanism (such as a cylinder or motor) needs to stop or pause at the end of each action cycle, waiting for the positioning pin to insert or remove from the positioning hole on the strip before proceeding to the next action. This working mode results in significant cycle time loss, limiting the improvement of production efficiency and equipment operating speed. Furthermore, the constant start-stop operation also generates a large amount of energy damage. Therefore, we propose a feeding mechanism for terminal strip processing. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism for terminal strip processing, which solves the problems of significant cycle time loss and energy waste in existing strip feeding mechanisms.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for processing terminal strips, comprising a base, wherein the top of the base is provided with a feeding mechanism for guiding the intermittent conveying of terminal strips, the feeding mechanism comprising:

[0005] The first guide rail is fixedly installed on the base, and its extension direction is arranged along the conveying direction of the material belt.

[0006] The movable frame is slidably connected to the top of the first guide rail;

[0007] A movable block is fixed to one side of the movable frame. The movable block has a vertical groove inside and a horizontal sliding groove communicating with the vertical groove on its front side.

[0008] The lifting frame is a frame structure, with one side wall slidably connected to the vertical groove of the movable block;

[0009] A positioning frame is installed at the bottom of the lifting frame;

[0010] A pair of feed pins are vertically mounted on the positioning frame, and the distance between the two feed pins is adapted to the spacing of the positioning holes on both sides of the terminal strip to be processed;

[0011] The positioning unit is used to control the lifting frame to perform lifting movements;

[0012] The feeding unit is used to drive the movable frame together with the positioning unit thereon to reciprocate along the first guide rail.

[0013] Furthermore, the positioning unit includes a positioning cylinder mounted on the movable frame, and the output end of the positioning cylinder is connected to a positioning block that is slidably disposed in the transverse groove of the movable block. An inclined positioning groove is provided in the positioning block.

[0014] A protruding column is fixed on the lifting frame, and one end of the protruding column extends into the positioning groove;

[0015] The positioning cylinder is configured to drive the positioning block to move horizontally, and through the cooperation of the positioning groove and the protruding column, the lifting frame is forced to move up and down in the vertical groove.

[0016] Furthermore, the feeding unit includes a feeding motor fixed on the base, a cam is mounted on the output shaft of the feeding motor, the cam is eccentrically connected to a connecting rod via a pin, and a push-pull block is rotatably connected to the end of the connecting rod away from the cam via a pin.

[0017] The push-pull block has an inverted U-shaped structure and is fitted inside the U-shaped structure of a connecting block, the top of which is connected to the movable frame.

[0018] The bottom of the connecting block is slidably connected to a second guide rail fixed on the base, and the guiding direction of the second guide rail is set along the conveying direction of the material belt.

[0019] Furthermore, the connecting block has a guide rod that passes through the U-shaped structure.

[0020] Furthermore, the length of the U-shaped structure of the connecting block is greater than the length of the push-pull block, so that when the push-pull block is driven by the connecting rod to make reciprocating motion, there is a time difference in the contact and pushing between it and the connecting block.

[0021] This utility model embodiment provides a feeding mechanism for processing terminal strip materials, which has the following beneficial effects:

[0022] 1. By designing the length of the U-shaped structure of the connecting block to be greater than the length of the push-pull block, a non-contact time window is created. Using this time window, the positioning unit can independently complete the insertion (positioning) and lifting (release) actions of the feeding pin, while the feeding motor that drives the reciprocating motion of the movable frame does not need to stop and wait, realizing continuous operation. This not only significantly improves the feeding cycle and the overall production efficiency of the equipment, but also reduces energy consumption compared to the mode where both drives need to be stopped or paused.

[0023] 2. The cam-linkage mechanism converts the continuous rotation of the motor into precise linear reciprocating motion. Combined with the double guide rail design, it ensures the straightness and stability of the movement of the movable frame and connecting block. The positioning unit adopts a simple mechanical structure of cylinder-driven inclined groove-protruding column to achieve lifting, which is accurate, reliable and has a low failure rate.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] See attached document Figure 1-5A feeding mechanism for processing terminal strip includes a base 1. A feeding mechanism is installed on the top of the base 1. The feeding mechanism includes a first guide rail 21, which is horizontally fixed to the base 1 by fasteners such as bolts. Its length direction is the conveying direction of the terminal strip. A movable frame 22 is slidably connected to the top of the first guide rail 21 through a slider or groove structure at its bottom, so that it can slide smoothly back and forth along the first guide rail 21.

[0033] The movable block 23 is fixed to the front side of the movable frame 22 by welding or bolting. The movable block 23 has a vertically extending vertical groove 231 inside and a horizontally extending horizontal sliding groove 232 on its front side. The vertical groove 231 and the horizontal sliding groove 232 are internally connected.

[0034] The lifting frame 24 has a rectangular frame structure. One side wall of the lifting frame 24 is embedded in the vertical groove 231 of the movable block 23 and can slide up and down along it. A positioning frame 25 is fixedly connected to the bottom of the lifting frame 24. A pair of feeding pins 26 are vertically installed on the positioning frame 25. The distance between the two pins precisely matches the spacing of the positioning holes on both sides of the terminal strip to be processed. The strip is not shown in the figure.

[0035] The positioning unit is responsible for controlling the lifting and lowering of the feed pin 26. It includes a positioning cylinder 271 fixed on the movable frame 22. The piston rod end of the positioning cylinder 271 is connected to a positioning block 272. The main body of the positioning block 272 is slidably accommodated in the transverse groove 232 of the movable block 23. An inclined positioning groove 273 is machined on the positioning block 272. At the same time, a protruding post 241 is fixedly installed on the frame of the lifting frame 24. The end of the protruding post 241 extends into the positioning groove 273. When the piston rod of the positioning cylinder 271 extends or retracts, it drives the positioning block 272 to move horizontally left and right in the transverse groove 232. Since the protruding post 241 is restricted by the inclined surface of the positioning groove 273, the horizontal movement of the positioning block 272 will force the protruding post 241 and the lifting frame 24 to rise or fall in the vertical groove 231, thereby driving the feed pin 26 to complete the action of inserting into the positioning hole of the material strip or pulling it out of the hole.

[0036] The feeding unit is responsible for driving the reciprocating motion of the entire moving part to pull the material belt. It includes a feeding motor 281 fixed on the base 1. A cam 282 is mounted on the output shaft of the feeding motor 281. One end of a connecting rod 283 is hinged to the eccentric position of the cam 282 by a pin, and the other end is hinged to a push-pull block 284 in an inverted U-shape by a pin. A U-shaped connecting block 285 has its U-shaped opening facing upward. The push-pull block 284 is inverted and fitted into the U-shaped cavity of the connecting block 285. The top of the connecting block 285 is fixedly connected to the movable frame 22, and its bottom is slidably connected to another second guide rail 286 fixed on the base 1 by a slider. The guiding direction of the second guide rail 286 is parallel to the first guide rail 21. In order to improve the smoothness of the movement, a guide rod 287 is also installed through the U-shaped cavity of the connecting block 285. The length of the U-shaped structure of the connecting block 285 in the front-back direction is greater than the length of the push-pull block 284 in the corresponding direction.

[0037] Working principle: In the initial state, the feed pin 26 is in the raised position and the material strip is in the initial working position.

[0038] When the positioning cylinder 271 is activated, it drives the positioning block 272 to move. Through the positioning groove 273 and the protrusion 241, the lifting frame 24 is lowered, and the two feed pins 26 are precisely inserted into the positioning holes on the material belt.

[0039] When the feed motor 281 starts and rotates continuously at a constant speed, the cam 282 drives the push-pull block 284 to move forward through the connecting rod 283. Since there is a gap between the push-pull block 284 and the connecting block 285, the push-pull block 284 will first move a distance without moving, and only after the gap is eliminated will it contact the connecting block 285 and push it forward together. The connecting block 285 drives the movable frame 22 and all its components to move forward a preset step distance along the first guide rail 21, thereby pulling the material belt forward one station.

[0040] When the feeding step is completed, the movable frame 22 reaches the end of the forward stroke. At this time, the push-pull block 284 starts to move in the opposite direction under the drive of the connecting rod 283. Also due to the gap caused by the length difference, the push-pull block 284 will first disengage from the connecting block 285 and have a brief empty return stroke. Taking advantage of this time difference, the positioning cylinder 271 moves in the opposite direction, driving the positioning block 272 back to its original position, so that the lifting frame 24 is lifted and the feeding pin 26 is pulled out from the positioning hole of the material belt.

[0041] After the feed pin 26 is fully pulled out, the push-pull block 284 finishes its empty return stroke and begins to contact the connecting block 285 and pull it backward, thereby quickly pulling the movable frame 22 back to its initial position and preparing to start the next feeding cycle.

[0042] Throughout the process, the feed motor 281 maintains a continuous and uniform rotation speed, without needing to stop or slow down while waiting for the feed pin 26 to move, thus achieving efficient and continuous intermittent feeding.
