Description

Technical Field

[0001] The present invention relates to the technical field of fuse processing, and particularly relates to a clamping and transferring mechanism for fuses. Background Art

[0002] A fuse, also known as a current fuse, mainly functions for overload protection. When the current in a circuit is abnormal and the temperature on the fuse rises to a certain degree, the fuse can cut off the current to protect other components in the circuit. During the production of fuses, when transferring the cut fuses, since the cross-sectional area of the fuse is small, in order to avoid accidental detachment of the fuse during the transfer process, a clamping mechanism is often required to clamp the fuse. At the same time, since the fuse needs to be transferred, a transmission mechanism is also required to drive the clamping mechanism to move. At this time, at least two drivers are required in the entire device to provide power for clamping and transferring, which leads to a more complex structure of the device; on the other hand, since at least two drivers are required for driving, control logic for their coordinated operation needs to be written for the two drivers. Especially during short-distance transfer, the transmission mechanism needs to move a relatively small distance, which is more likely to cause errors between the clamping and transferring actions, resulting in transfer failure. Summary of the Invention

[0003] Aiming at the deficiencies in the prior art, the main object of the present invention is to provide a clamping and transferring mechanism for fuses, which controls the clamping and transfer of fuses through a single driver to avoid errors in the coordinated operation of multiple drivers.

[0004] To achieve the above object and other advantages of the present invention, the present invention aims to provide a clamping and transferring mechanism for fuses, including:

[0005] Including:

[0006] A support;

[0007] Two clamping parts pivotally connected to the base surface of the support, which are used for clamping the fuse;

[0008] A pushing part, which is used to drive the two clamping parts to open; and

[0009] A driver, which is used to drive the pushing part to reciprocate vertically;

[0010] Wherein, the clamping parts are a first clamping part and a second clamping part. A second clamping claw is installed at one end of the second clamping part, and a convex part is provided on the side wall of the other end; the driver drives the pushing part to drive the first clamping part to rotate;

[0011] A stop portion is also installed on the support, which is used to limit the rotation distance of the second clamping portion. When the second clamping portion abuts against the stop portion, the second clamping portion is in a balanced state. When the second clamping portion is in a balanced state, the convex portion of the second clamping portion is located on the moving path of the pushing portion;

[0012] A guide chute is provided on the support. The movement path of the pushing portion is restricted by the guide chute so that it reciprocates between the starting end and the terminal end, and the starting end is above the terminal end;

[0013] When the pushing portion is located at the starting end, the first clamping portion is close to the stop portion; when the pushing portion is located at the terminal end, the pushing portion abuts against the convex portion, causing the second clamping portion to deviate from the balanced state and fall towards the first clamping portion.

[0014] Preferably, the pushing portion includes a roller, and the first clamping portion includes a guide sliding surface. The roller is attached to the guide sliding surface and is driven by a driver so that the roller rolls on the guide sliding surface to drive the first clamping portion to rotate and close the two clamping portions.

[0015] Preferably, the first clamping portion and the second clamping portion are pivotally connected by a pivot shaft, and the pivot shaft is installed on the support.

[0016] Preferably, the guide sliding surface is inclined relative to the vertical line of the first clamping portion. The first clamping portion and the stop portion are arranged on both sides of the axis of the pivot shaft, and the vertical line of the first clamping portion is always on the other side of the pivot shaft opposite to the side where the stop portion is provided.

[0017] Preferably, when the second clamping portion is in a balanced state, the vertical line of the second clamping portion is located at the rotation center of the pivot shaft.

[0018] Preferably, when the second clamping portion is in a balanced state, the vertical line of the second clamping portion is located between the rotation center of the pivot shaft and the stop portion, and the vertical line of the second clamping portion approximately falls on the rotation center of the pivot shaft.

[0019] Preferably, when the pushing portion moves from the terminal end to the starting end, the second clamping portion closes on the first clamping portion, and the second clamping portion rotates forward along with the first clamping portion so that the second clamping portion and the first clamping portion clamp the fuse close to the stop portion;

[0020] When the pushing portion moves from the starting end to the terminal end, the first clamping portion rotates reversely so that the first clamping portion moves away from the second clamping portion; when the pushing portion moves to the terminal end, at this moment, the convex portion is pushed by the pushing portion, causing the second clamping portion to rotate reversely under its own weight and close towards the first clamping portion.

[0021] Preferably, a mounting seat is installed on the power output end of the driver, and the pushing portion is received on the mounting seat;

[0022] Among them, the pushing part further includes an installation shaft. The roller is sleeved on the installation shaft, and while the installation shaft is inserted into the installation seat, it extends into the guide chute, so that the installation shaft slides along the direction of the guide chute.

[0023] Preferably, the installation seat has a U-shaped structure, and the power output end is connected to the bottom surface of the installation seat; a shaft hole corresponding to the pushing part is provided on the side wall of the installation seat, and a relief groove is provided on the bottom surface of the installation seat so that the first clamping part and the second clamping part can pass through the relief groove and abut against the roller.

[0024] Preferably, the clamping part includes a clamping jaw and an extension block. The clamping jaw is fixedly connected to one end of the extension block, and an arc-shaped notch is provided on the clamping jaw. When the two clamping parts are closed, the notches on the two clamping jaws cooperate with each other to form a clamping position for clamping the fuse.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] The present invention provides a clamping and transfer mechanism for a fuse. The driver drives the pushing part to move to drive the first clamping part and the second clamping part to perform the actions of closing or unfolding to clamp the fuse. At the same time, the driver drives the first clamping part and the second clamping part to move simultaneously to transfer the fuse.

[0053] In the accompanying drawings, for clarity, the shapes and dimensions may be enlarged, and the same reference numerals will be used throughout the drawings to indicate the same or similar components.

[0054] Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art to which the present invention pertains. The terms "first", "second" and similar terms used in the specification of this patent application of the present invention do not denote any order, quantity or importance, but are only used to distinguish different components. Similarly, the terms such as "a", "an" or "the" do not denote a quantity limitation, but mean that there is at least one. The terms such as "comprising" or "including" mean that the elements or items appearing before "comprising" or "including" cover the elements or items listed after "comprising" or "including" and their equivalents, and do not exclude other elements or items. The terms such as "upper", "lower", "left", "right" etc. are only used to indicate relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0055] In the following description, terms such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are defined with respect to the structures shown in the respective drawings. In particular, "height" corresponds to the dimension from the top to the bottom, "width" corresponds to the dimension from the left to the right, and "depth" corresponds to the dimension from the front to the back. They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientations should not be construed as restrictive terms.

[0056] Terms related to attachment, connection, etc. (e.g., "connect" and "attach") refer to the relationship in which these structures are directly or indirectly fixed or attached to each other through an intermediate structure, as well as a movable or rigid attachment or relationship, unless otherwise explicitly stated.

[0057] According to an embodiment of the present invention in combination with Figures 1-6As can be seen, a clamping and transferring mechanism for a fuse includes a support 410, a clamping part, a pushing part 460, and a driver 420; the number of clamping parts is two, and the two clamping parts are pivotally connected to the base surface of the support 410, and the fuse is clamped by the closing of the two clamping parts; the pushing part 460 is used to drive the two clamping parts to open; the driver 420 is used to drive the pushing part 460 to reciprocate vertically. The pushing part 460 is driven by the driver 420 to drive the clamping part to open so that the clamping part can move to both sides of the fuse;

[0058] Specifically, the two clamping parts are respectively a first clamping part 430 and a second clamping part 440. The driver 420 drives the pushing part 460 to drive the first clamping part 430 to rotate; on the other hand, a second clamping jaw 441 is installed at one end of the second clamping part 440, and a convex part protrudes outward from the side wall at the other end of the second clamping part 440;

[0059] A stop part 450 is also installed on the support 410, which is used to limit the rotation distance of the second clamping part 440. When the second clamping part 440 abuts against the stop part 450, the second clamping part 440 is in a balanced state. When the second clamping part 440 is in a balanced state, the convex part of the second clamping part 440 is located on the moving path of the pushing part 460;

[0060] A guide chute 411 is provided on the support 410. Specifically, the guide chute 411 extends on the support 410 along a perpendicular straight line direction. The moving path of the pushing part 460 is restricted by the guide chute 411 so that it reciprocates between the starting end and the terminal end, and the starting end is above the terminal end. Specifically, the starting end is the end of the guide chute 411 at the highest point in the vertical direction, and the terminal end is the end of the guide chute 411 at the lowest point in the vertical direction;

[0061] Furthermore, the pushing part 460 includes a roller 462, and the first clamping part 430 includes a guide sliding surface 4321. The roller 462 is attached to the guide sliding surface 4321 and is driven by the driver 420 so that the roller 462 rolls on the guide sliding surface 4321 to drive the first clamping part 430 to rotate. The guide sliding surface 4321 is inclined relative to the plumb line of the first clamping part 430, so that when the pushing part 460 rolls on the guide sliding surface 4321, it forces the first clamping part 430 to rotate around the axis of its pivot shaft. On the other hand, the center of gravity of the first clamping part 430 is always located on the same outer side of its pivot shaft, so that the gravity of the first clamping part 430 always presses on the pushing part 460 to ensure that when the driver 420 drives the pushing part 460 to move, the pushing part 460 always drives the first clamping part 430. More specifically, the position of the guide chute 411 is provided on one outer side of the pivot shaft of the first clamping part 430, and the center of gravity of the first clamping part 430 and the guide chute 411 are on the same side of the pivot shaft of the first clamping part 430.

[0062] When the pushing part 460 is at the starting end, the first clamping part 430 is close to the stop part 450. While the stop part 450 restricts the rotation angle of the second clamping part 440, it also restricts the rotation angle of the driving part 420 to drive the first clamping part 430 to rotate. When the pushing part 460 is at the terminal end, the pushing part 460 abuts against the convex part, causing the second clamping part 440 to deviate from the balanced state and fall towards the first clamping part 430 to close the two clamping parts.

[0063] Specifically, the first clamping part 430 and the second clamping part 440 are pivotally connected through a pivot shaft 412, and the pivot shaft 412 is installed on the support 410, enabling the first clamping part 430 and the second clamping part 440 to rotate around the same axis. The first clamping part 430 and the stop part 450 are arranged on both sides of the axis of the pivot shaft 412, and the plumb line of the first clamping part 430 is always located on the other side of the pivot shaft 412 opposite to the side where the stop part 450 is provided.

[0064] As Figures 7-10 As shown in detail, the working steps of the clamping and transferring mechanism include:

[0065] When the pushing part 460 is at the starting end, the second clamping part 440 and the first clamping part 430 are closed at the first position close to the stop part 450;

[0066] When the pushing part 460 is at the terminal end, the second clamping part 440 and the first clamping part 430 are closed at the second position far from the stop part 450;

[0067] When the pushing part 460 moves from the terminal end to the starting end, the second clamping part 440 closes on the first clamping part 430, and the second clamping part 440 rotates forward along with the first clamping part 430, causing the second clamping part 440 and the first clamping part 430 to clamp the fuse close to the stop part 450, that is, the second clamping part 440 and the first clamping part 430 move from the second position to the first position;

[0068] When the pushing part 460 moves from the starting end to the terminal end, the first clamping part 430 rotates in the reverse direction, causing the first clamping part 430 to move away from the second clamping part 440. Specifically, when the pushing part 460 moves from the starting end to the terminal end and the pushing part 460 does not touch the convex part, the first clamping part 430 moves relative to the second clamping part 440. When the pushing part 460 moves from the starting end to the terminal end, the first clamping part 430 moves from the first position to the second position. When the pushing part 460 moves to the terminal end, at this moment, the convex part is pushed by the pushing part 460, causing the second clamping part 440 to rotate in the reverse direction under its own weight and close towards the first clamping part 430 at the second position to clamp the fuse.

[0069] After gripping the fuse, the clamping and transfer mechanism moves between the first position and the second position. Moreover, the clamping and transfer mechanism uses a driver 420 to simultaneously achieve the clamping and transfer actions, reducing the use of drive components to lower the manufacturing cost. At the same time, the clamping and transfer actions are achieved through a rigid structure, simplifying the control logic and avoiding operation errors.

[0070] Wherein, when the second clamping part 440 is in a balanced state, the plumb line of the second clamping part 440 is at least not on the same side of the axis of the pivot shaft 412 as the plumb line of the first clamping part 430. And when the pushing part 460 moves to the terminal to push the protruding part, it forces the second clamping part 440 to rotate until the plumb line of the second clamping part 440 is on the same side of the axis of the pivot shaft 412 as the plumb line of the first clamping part 430. In a preferred embodiment, when the second clamping part 440 is in a balanced state, the plumb line of the second clamping part 440 is located at the rotation center of the pivot shaft 412.

[0071] In another preferred embodiment, when the second clamping part 440 is in a balanced state, the plumb line of the second clamping part 440 is located between the rotation center of the pivot shaft 412 and the stop part 450, and the plumb line of the second clamping part 440 approximately falls on the rotation center of the pivot shaft 412.

[0072] The clamping part includes a clamping jaw and an extension block. The clamping jaw is fixedly connected to one end of the extension block. The second clamping part 440 includes a second clamping jaw 441 and a second extension block 442. The second extension block 442 at least includes a clamping initial end 4421, an extension rod 4422 and a protruding end 4423. The clamping initial end 4421, the extension rod 4422 and the protruding end 4423 are integrally combined in sequence to form the second extension block 442. A protruding block is formed at the protruding end 4423. The second clamping jaw 441 is installed on the clamping initial end 4421. The second clamping part 440 is formed by connecting the second clamping jaw 441 to the second extension block 442. The pivot shaft 412 is connected to the extension rod 4422. Specifically, the weight of the second clamping jaw 441 is much greater than that of the second extension block 442, so that the center of gravity of the second clamping part 440 is close to the second clamping jaw 441. The first clamping part 430 includes a first clamping jaw 431 and a first extension block 432. The first clamping jaw 431 is fixedly installed at one end of the first extension block 432. A guiding sliding surface 4321 is arranged at the other end of the first extension block 432.

[0073] In a preferred embodiment, a mounting seat 422 is installed on the power output end 4211 of the driver 420, and the pushing part 460 is received on the mounting seat 422; wherein, the pushing part 460 further includes a mounting shaft 461, the roller 462 is sleeved on the mounting shaft 461, and while the mounting shaft 461 is inserted into the mounting seat 422, it extends into the guide chute 411, so that the mounting shaft 461 slides along the direction of the guide chute 411; mounting blocks 463 are installed at both ends of the mounting shaft 461, and the two mounting blocks 463 are located on both side surfaces of the support 410, so that the mounting blocks 463 are attached to the outside of the guide chute 411.

[0074] The mounting seat 422 has a U-shaped structure, and the power output end 4211 is connected to the bottom surface of the mounting seat 422; a shaft hole 4223 corresponding to the pushing part 460 is opened on the side wall 4221 of the mounting seat 422, and a relief groove 4222 is provided on the bottom surface of the mounting seat 422, so that the first clamping part 430 and the second clamping part 440 pass through the relief groove 4222 and abut against the roller 462.

[0075] The first jaw 431 and the second jaw 441 include a first clamping body 4311 and a second clamping body 4411, and a first notch 4312 and a second notch 4412 are respectively opened on the first clamping body 4311 and the second clamping body 4411. The jaws are provided with arc-shaped notches, and the first notch 4312 and the second notch 4412 are semi-circular. When the two clamping parts are closed, the first notch 4312 and the second notch 4412 cooperate with each other to form a clamping position for clamping the fuse.

[0076] Although the embodiments of the present invention have been disclosed above, it is not limited to only the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to specific details.
