Referring to fig. 2 to 8, according to the electromagnetic component end trimming apparatus provided in the embodiment of the present invention, an electromagnetic component 40 includes an insulating base 401 and a magnetic core coil 402, the insulating base 401 has a conductive pin 401a, and an end of the magnetic core coil 402 is wound on the conductive pin 401a to form a hitching end 402a, the electromagnetic component end trimming apparatus includes two stationary knife bases 10, a movable knife member 20 and a driving apparatus 30.
Specifically, two of the fixed tool seats 10 are oppositely arranged in a first direction and define a work positioning space adapted to position the electromagnetic element 40, and each of the fixed tool seats 10 has a fixed tool bit 101. That is, the electromagnetic element 40 after the hitching is completed can be just clamped in the workpiece positioning space between the two stationary blade seats 10.
The movable cutter element 20 is located between the two fixed cutter seats 10, the movable cutter element 20 is provided with a cutter head 201, and the cutter head 201 is provided with two movable cutter edges 201a which are oppositely arranged in the first direction. The movable cutter element 20 can swing back and forth between the two fixed cutter seats 10, in the swing process, two oppositely-facing movable cutter blades 201a on the movable cutter element 20 are respectively matched with the fixed cutter seats 10 on two sides, namely one movable cutter blade 201a is matched with the fixed cutter seat 10 opposite to the same side, and the movable cutter blade 201a is used for cutting off the hitching leg thread head 402a on the fixed cutter seat 10.
The driving means 30 is adapted to drive the movable cutter element 20 to switch between a central position, a first cutting position and a second cutting position, which are located on either side of the central position.
When the movable cutter element 20 moves from the center position to the first cutting position, one movable blade 201a of the cutter head 201 abuts one stitch line head 402a of the electromagnetic element 40 against the fixed blade head 101 of one of the two fixed blade seats 10 and cuts off; when the movable cutting blade 20 moves from the central position to the second cutting position, the other movable cutting blade 201a of the cutting head 201 presses the other stitch-hanging thread head 402a of the electromagnetic element 40 against the fixed cutting head 101 of the other of the two fixed cutting bases 10 and cuts the thread.
That is, the driving device 30 can drive the movable cutter element 20 to switch between a center position, in which the movable cutter element 20 is held at a position right in the middle of the two stationary blade seats 10, and a first cutting position, in which both the movable blades 201a are separated from the two stationary blade seats 10, and a second cutting position. When the driving device 30 drives the movable cutter element 20 to move to the first cutting position, the movable blade 201a on one side of the movable cutter element 20 moves to the fixed cutter base 10 (one of the fixed cutter bases 10) on the same side, and the stitch-hanging thread head 402a on the electromagnetic element 40 is abutted against the fixed cutter base 10 and cut off. When the driving device 30 drives the movable cutter element 20 to move to the other side to the second cutting position, the movable cutter edge 201a on the other side of the movable cutter element 20 moves to the fixed cutter base 10 on the same side, and the leg hanging thread head 402a on the electromagnetic element 40 is abutted against the fixed cutter base 10 (the other fixed cutter base 10) and is cut off.
In a specific application, the electromagnetic element thread end shearing device can be arranged on a multi-axis mechanical arm. The electromagnetic element 40 completes the hitching in the hitching mechanism. The multi-axis mechanical arm can drive the electromagnetic element thread end shearing device to move into the stitch hanging mechanism and descend to a preset height, so that the two fixed cutter seats 10 are positioned outside the electromagnetic element 40, namely the electromagnetic element 40 is better clamped in a workpiece positioning space between the two fixed cutter seats 10, at this time, one stitch hanging thread end 402a on the electromagnetic element 40 is just positioned between one fixed cutter seat 10 and one movable cutter edge 201a of the cutter head 201, and the other stitch hanging thread end 402a on the electromagnetic element 40 is just positioned between the other fixed cutter seat 10 and the other movable cutter edge 201a of the cutter head 201. The movable cutter 20 is driven by the driving device 30 to move from the center position to the first cutting position and from the center position to the second cutting position, thereby cutting off the two hitching leg wire ends 402a at a time.
According to the electromagnetic element thread end shearing device provided by the embodiment of the invention, the movable cutter element 20 is positioned between the two fixed cutter seats 10 and can be switched among a middle position, a first cutting position and a second cutting position, when the movable cutter element 20 moves from the middle position to the first cutting position, one movable blade 201a of the cutter head 201 supports one thread end 402a of the electromagnetic element 40 against the fixed cutter head 101 of one of the two fixed cutter seats 10 and cuts the thread end; when the movable cutter element 20 moves from the middle position to the second cutting position, the other movable blade 201a of the cutter head 201 abuts against the other stitch-hanging thread head 402a of the electromagnetic element 40 on the other fixed blade head 101 of the two fixed blade seats 10 and cuts off the stitch-hanging thread head 402a, so that the stitch-hanging thread head 402a of the electromagnetic element 40 can be automatically cut off, and the production and processing efficiency and the product quality are improved.
In some embodiments of the present invention, there are four conductive pins 401a, and a hitching leg head 402a is formed on each of the four conductive pins 401 a. For example, the electromagnetic component 40 has two coils 402, each coil 402 has two ends at the beginning and the end, the two coils 402 have four ends, the insulating base 401 has four conductive pins 401a, and the four ends are wound on the four conductive pins 401a in a one-to-one correspondence, so that four hitching-pin ends 402a can be formed. Illustratively, the four thread ends are arranged symmetrically two by two and extend in the second direction.
The number of the fixed cutter heads 101 on each fixed cutter seat 10 is two, and the two fixed cutter heads 101 are oppositely arranged in a second direction, and the second direction is perpendicular to the first direction; the number of the cutter heads 201 on the movable cutter element 20 is two, and the two cutter heads 201 are arranged oppositely in the second direction.
One of the two cutting heads 201 is located between two opposite fixed cutting heads 101 on the two fixed tool seats 10, and is used for cutting off the hitching leg wire heads 402a on two of the four conductive pins 401 a; the other of the two cutting heads 201 is located between the other two opposite fixed cutting heads 101 on the two fixed tool seats 10, and is used for cutting off the hitching leg wire heads 402a on the other two of the four conductive pins 401 a.
That is, two fixed tool bits 101 on one fixed tool seat 10 correspond to two fixed tool bits 101 on the other fixed tool seat 10 one by one, and two groups of fixed tool bits 101 are correspondingly formed, and the two fixed tool bits 101 in each group of fixed tool bits 101 are oppositely arranged in the first direction. And two cutter heads 201 correspond to two sets of fixed cutter heads 101 one to one, and each cutter head 201 is located between two fixed cutter heads 101 of the corresponding set of fixed cutter heads 101.
Thus, when the driving device 30 drives the movable cutter element 20 to move from the middle position to the first cutting position, the two movable cutter blades 201a on one side of the two cutter heads 201 respectively cooperate with the fixed cutter heads 101 on the two fixed cutter seats 10 on the same side, and the cutting of the two hitching leg wire heads 402a on the side is completed. And when the driving device 30 drives the movable cutter element 20 to move from the middle position to the second cutting position, the two movable cutter blades 201a on the other side of the two cutter heads 201 are respectively matched with the fixed cutter heads 101 on the two fixed cutter seats 10 on the same side to cut off the two stitch hanging wire heads 402a on the side, so that the four stitch hanging wire heads 402a can be cut off, and thus, the four stitch hanging wire heads 402a can be cut off quickly, the efficiency is high, and the cutting is reliable and stable.
Referring to fig. 5 to 8, in an embodiment of the present invention, the stationary blade 101 has a stop surface S1a, and the first direction is perpendicular to the stop surface S1 a. When the electromagnetic element 40 is located in the workpiece positioning space, the conductive pin 401a is located inside the stop surface S1a and is close to the stop surface S1 a.
In the cutting operation, when the cutter head 201 moves toward the fixed blade base 10, the movable blade 201a of the cutter head 201 applies pressure to the stitch yarn head 402a, and since the stitch yarn head 402a is formed by winding the stitch yarn head on the coil 402 around the conductive pin 401a, the stitch yarn head 402a extends outward around the conductive pin 401a, and when the movable blade 201a applies pressure to the stitch yarn head 402a, part of the pressure is transmitted to the conductive pin 401a through the stitch yarn head 402a. In this embodiment, the stop surface S1a is disposed on the fixed blade seat 10, and when the stop surface S1a stops at the outer side of the conductive pin 401a, the stop surface S1a is used to support the conductive pin 401a, so as to prevent the conductive pin 401a from deforming outward due to stress, which may result in a problem that the switching of the pin head 402a is not smooth, and the quality of the product with the deformed conductive pin 401a is not high.
In other words, by the support action of the stop surface S1a on the conductive pin 401a, it is ensured that when the movable blade 201a applies pressure to the stitch stub 402a, the conductive pin 401a does not deform outward, the stitch stub 402a smoothly abuts against the fixed blade seat 10 and is reliably cut off, and the reliability of cutting the stitch stub and the product quality are improved.
It should be understood that the movable blade 201a may cut the stitch yarn head 402a by abutting against the stop surface S1a, or may cut the stitch yarn head 402a by abutting against another position of the fixed blade base 10, which is not intended to limit the present invention.
Referring to fig. 5 to 8, in an embodiment of the present invention, the fixed blade head 101 has a slope S1b, the slope S1b intersects with the stop surface S1a to form a fixed blade edge 101a, and the movable blade edge 201a is substantially opposite to the fixed blade edge 101a in the first direction. Preferably, the angle between the inclined surface S1b and the stop surface S1a is in the range of 90 ° to 180 °.
In this embodiment, the inclined surface S1b and the stop surface S1a intersect to form the fixed blade edge 101a, and when the movable blade edge 201a approaches the fixed blade base 10, the hitching leg wire end 402a abuts against the fixed blade edge 101a, and under the pressing of the movable blade edge 201a, a shearing force is easily formed on the fixed blade edge 101a, and the hitching leg wire end 402a is more easily cut off from the position of the fixed blade edge 101 a. In addition, in the process, the hitching leg wire head 402a deflects towards the inclined surface S1b and is attached to the inclined surface S1b, so that the cut end after cutting is favorable for forming a wrapping and attaching state on the conductive pin 401a instead of deviating from a loose state of the conductive pin 401a, and the wrapping and attaching state is favorable for improving the reliability of the electrical connection between the coil 402 and the conductive pin 401a, and can form more reliable electrical connection after spot welding at the position.
In one embodiment of the present invention, the bottom of the cutter head 201 has a knife groove H2a for cooperating with the fixed cutter head 101, the knife groove H2a is opened to an open side toward one side of the fixed cutter head 101, and the movable blade 201a is formed on the inner wall of the knife groove H2 a.
That is, the cutter head 201 is provided with the siping H2a, and when the movable cutter 20 moves to the first cutting position, the fixed cutter 101 is received by the siping H2a, so that the movable blade 201a can be brought close to the fixed cutter 101, and the hitching leg wire end 402a can be smoothly cut. In addition, the knife groove H2a can be used for inserting the conductive pin 401a, and the pin hanging thread head 402a on the conductive pin 401a can be positioned between the fixed cutter head 101 and the movable cutter blade 201a, so that the thread head can be cut accurately and reliably.
Preferably, the bottom of the cutter head 201 is provided with a notch H2b, and the notch H2b is communicated with the cutter groove H2a and is opened in the second direction to avoid the stitch line head 402a when the electromagnetic element 40 is inserted into the workpiece positioning space. With the provision of the notch H2b communicating with the pocket H2a in the cutter head 201, when the work positioning space of the electromagnetic element thread end cutting device is positioned and fitted with the electromagnetic element 40, the conductive pin 401a on the electromagnetic element 40 is inserted into the guide groove, and hitching leg end of a thread 402a on the conductive pin 401a just can extend outwards along the second direction from the notch H2b, so that the hitching leg end of a thread 402a can be positioned between the fixed cutter head 101 and the movable cutter blade 201a and extend outwards, thereby being convenient for cutting off the hitching leg end of a thread 402a and improving the reliability of cutting off.
In an embodiment of the present invention, the fixed cutter holder 10 is provided with a positioning groove H1a for positioning the insulating holder 401, and the two fixed cutter heads 101 are located at two sides of the positioning groove H1a in the second direction.
That is to say, set up constant head tank H1a on two stationary knife seat 10, this constant head tank H1a and electromagnetic element 40's insulating seat 401 adaptation, just can ensure insulating seat 401's both sides card when two stationary knife seat 10 descend in two constant head tanks H1a, so, ensure that electromagnetic element 40 keeps fixed, in the follow-up cutting process, based on relatively stable position relation, can cut off hitching leg end of a thread 402a smoothly.
