That is, the driving device 202 may drive the cutter 201 to move in a direction approaching the stop surface S12 or away from the stop surface S12, and when the cutter 201 moves in a direction approaching the stop surface S12, the cutter 201 pushes the toe end against the stop surface S12 and cuts it off, and then the cutter 201 moves in a direction away from the stop surface S12.
In a specific application, during the cutting operation of the hitching leg wire end of the electromagnetic element 50, the electromagnetic element 50 may be moved and loaded onto the positioning seat 10 by using a manipulator, and then the cutter mechanism 20 is utilized to cut the wire end.

Referring to fig. 7, in one embodiment of the present invention, the insulating base 502 has a protruding portion extending in the same direction as the conductive pin 5021, and the protruding portion generally plays a supporting and isolating role with the circuit board, that is, when the electromagnetic element 50 is applied to a specific product, the insulating base 502 is plugged onto the circuit board, and the protruding portion contacts with the circuit board, so that a gap is formed between the electromagnetic element 50 and the circuit board. The positioning seat 10 is provided with a positioning opening H10 matched with the protruding part.
In this embodiment, the positioning opening H10 on the positioning seat 10 matching with the protruding portion can enable the protruding portion to be just clamped in the positioning opening H10 when the positioning seat 10 is matched with the electromagnetic element 50 in a loading manner, so that the positioning seat 10 and the electromagnetic element 50 can be kept relatively positioned and fixed by utilizing the matching of the protruding portion and the positioning opening H10.
Referring to fig. 7 to 11, in an embodiment of the present invention, the cutter 201 includes a blade 2011, a first positioning portion 2012 and a second positioning portion 2013, wherein the blade 2011 is used for cutting off the hook wire end, and preferably, the blade 2011 is opposite to the stop surface S12.
The first positioning portion 2012 and the second positioning portion 2013 are disposed opposite to each other and define an open slot H20 therebetween, and the open slot H20 is adapted to the stop table 101. The blade 2011 is provided in the open groove H20 and extends in parallel. When the driving device 202 drives the cutter 201 to move to a predetermined position, the stop table 101 is located in the opening H20, and the blade abuts against the stop surface S12 to cut off the thread end.
In this embodiment, the first positioning portion 2012 and the second positioning portion 2013 define the opening H20, and the blade 2011 is disposed in the opening H20 and extends in parallel, so that when the driving device 202 drives the cutter 201 to move toward the stopper 101, the stopper 101 is inserted into the opening H20, so that the cutter 201 is ensured to engage with the stopper 101, the cutter 201 moves reliably, and the blade 2011 can cut off the hitching leg wire end on the stopper surface S12 accurately and reliably.
Advantageously, the open slot H20 is formed in a V-shape, and the open slot H20 has two side walls, that is, two opposite side surfaces on the first positioning portion 2012 and the second positioning portion 2013 of the open slot H20. The stopping platform 101 further has a first inclined surface S10 and a second inclined surface S11, the stopping surface S12 is located between the first inclined surface S10 and the second inclined surface S11, when the stopping platform 101 is located in the open slot H20, the first inclined surface S10 is attached to one of two side walls of the open slot H20, and the second inclined surface S11 is attached to the other of two side walls of the open slot H20.
That is, the first inclined surface S10 and the second inclined surface S11 on the stop table 101 correspond to two sidewalls of the open slot H20, respectively, and an included angle formed between the first inclined surface S10 and the second inclined surface S11 is adapted to the open slot H20. When the driving device 202 drives the cutter 201 to move toward the stop table 101, the two side walls of the opening groove H20 interact with the first inclined surface S10 and the second inclined surface S11 on the stop table 101, which plays a guiding role, and guides the stop table 101 to be accurately inserted into the opening groove H20, so that the cutting edge 2011 accurately and reliably cuts off the hitching leg wire end on the stop surface S12, and the tangent line is ensured to be more stable and reliable.
More advantageously, the predetermined distance is provided between the blade 2011 and the opening of the open slot H20, that is, the blade 2011 is hidden in the open slot H20, so that the blade can be ensured to move accurately toward the stop surface S12 under the guiding cooperation between the open slot H20 and the stop table 101.
Referring to fig. 7 to 11, in an embodiment of the present invention, a clearance groove H21 is defined between the blade 2011 and the second positioning portion 2013 for clearance of the conductive pin 5021 of the insulating base 502. Since the conductive pin 5021 is provided on the insulating base 502, and when the electromagnetic element 50 is in loading engagement with the positioning base 10, the hitching leg wire end on the electromagnetic element 50 is close to the stop surface S12 and opposite to the blade 2011, in this embodiment, a clearance groove H21 is defined between the blade 2011 and the second positioning portion 2013, and when the stop table 101 is inserted into the opening groove H20, the conductive pin 5021 is just located in the clearance groove H21, so as to avoid mechanical interference between the conductive pin 5021 and the cutter 201, and ensure that the blade 2011 can abut against the stop surface S12 to cut off the hitching leg wire end on the conductive pin 5021.
Preferably, the extending direction of the blade 2011 is perpendicular to the extending direction of the thread end, and the first positioning portion 2012 is provided with a clearance H22 for avoiding the thread end. Generally, after the hanging pin, the extending direction of the hanging pin line head is perpendicular to the conductive pin 5021, and the extending direction of the blade 2011 is also perpendicular to the extending direction of the hanging pin line head, so the first positioning portion 2012 easily interferes with the hanging pin line head, which causes the first positioning portion 2012 to bend the hanging pin line head, which is not beneficial to the wire cutting operation. In order to avoid mechanical interference between the first positioning portion 2012 and the hitching leg wire end when the cutter 201 moves toward the stopper 101, the clearance H22 is provided on the first positioning portion 2012, so that the first positioning portion 2012 does not interfere with the hitching leg wire end during the movement of the blade 2011 to contact with the stopper surface S12, thereby ensuring that the blade 2011 can reliably cut the hitching leg wire end.
Referring to fig. 1 to 4, in an embodiment of the present invention, the electromagnetic component wire cutting apparatus further includes a fixing base 30 and a moving mechanism 40, wherein the positioning base 10 and the cutter 201 are mounted on the fixing base 30. The moving mechanism 40 is connected to the fixed base 30, and is used for driving the fixed base 30 to move so as to move the positioning base 10 to be in loading fit with the electromagnetic element 50.
That is, the moving mechanism 40 can drive the fixing base 30 to move, so that the positioning base 10 on the fixing base 30 moves towards the electromagnetic element 50 to realize loading cooperation, for example, the electromagnetic element 50 completes the operation of hanging feet on the hanging foot mechanism, and then the moving mechanism 40 drives the fixing base 30 to move, so that the positioning structure of the positioning base 10 cooperates with the electromagnetic element 50 to complete loading, thus, automatic hanging feet and wire cutting operation can be completed by cooperation with the hanging foot mechanism, and the automation degree is higher.
Referring to fig. 9-12, in some embodiments of the present invention, the electromagnetic element 50 has two first leg wire ends 5012a and two second leg wire ends 5012b, the two first leg wire ends are oppositely arranged in a first direction and extend along a second direction; the two second hanging wire heads are on the same straight line and extend towards opposite directions in the first direction.
Correspondingly, the number of the stop platforms 101 is four, two of the four stop platforms 101 are respectively positioned at two sides of the positioning seat 10 in the first direction, and the other two of the four stop platforms 101 are positioned at the same side of the positioning seat 10 in the second direction.
The number of cutters 201 is four, two of the four cutters 201 are respectively positioned at two sides of the positioning seat 10 in the first direction and correspond to the two stopping platforms 101 one by one, and the open grooves H20 of the two cutters 201 are opposite in the first direction; two other cutters 201 are located on the same side of the positioning seat 10 in the second direction and are in one-to-one correspondence with the two other stop platforms 101, and the open grooves H20 of the two other cutters 201 face the same side of the second direction.
