Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

A welding strip cutting mechanism 10 and a cutting system having a segmented welding strip 60 according to an embodiment of the present invention will be described with reference to fig. 1-2.

According to the utility model discloses solder strip cutting mechanism 10 of the embodiment of the first aspect includes: two supports 11, two cutters 12 arranged oppositely and a blocking mechanism.

The two supports 11 are oppositely arranged, and at least one of the two supports 11 is a movable support which can move along a first direction. The two cutters 12 are respectively fixedly connected to the two supports 11 so as to be driven by the supports 11 to move towards or away from each other, the two cutters 12 are closed to cut the welding strip 60 when moving towards each other, and a gap for the welding strip 60 to pass through is formed between the two cutters 12 when moving away from each other; the blocking mechanism comprises two oppositely arranged baffle plates 13, the two baffle plates 13 are correspondingly connected with the two supports 11 respectively, the baffle plates 13 and the cutters 12 which are connected on the same support 11 are opposite in the second direction, and when the two supports 11 move oppositely, the two baffle plates 13 are constructed to be closed before the two cutters 12 are closed.

In the embodiment shown in fig. 1, two supports 11 of the cutting mechanism 10 are distributed up and down, wherein one support 11 can be arranged to move towards the other support 11, or both supports 11 can be arranged to move, and the moving direction of the supports 11 is perpendicular to the moving direction of the welding strip 60. Fixedly connected with cutter 12 respectively on two supports 11, the one end that deviates from mutually with cutter 12 of two supports 11 is connected with baffle 13 respectively, cuts solder strip 60 when two cutters 12 are the motion in opposite directions under the drive of support 11, can set up the height of baffle 13 to make baffle 13 closed earlier before cutter 12 is closed cuts. Similarly, if the cutters 12 and the baffle 13 move away from each other under the driving of the support 11, a gap is formed between the two cutters 12 and between the baffles 13, through which the solder strip 60 can pass.

It should be noted that the closing of the two blocking plates 13 does not mean that there is no gap between the two blocking plates 13, and here means that the two blocking plates 13 are in a state of being close to each other, the two blocking plates 13 jointly clamp the solder strip 60, and there is a gap between the two blocking plates 13 for the solder strip 60 to pass through.

From this, through the setting of removal support, realize the switching of baffle 13 and the switching of cutter 12, baffle 13 is closed earlier when cutting at every turn, then cutter 12 cuts solder strip 60, baffle 13 just has fallen before cutting because cutter 12 cuts, closed baffle 13 can cut the solder strip head that drops after to and block each other, outside guaranteeing that solder strip head can not fly out baffle 13, when avoiding solder strip 60 to glue solder strip head, still can not influence the process normal operating outside cutting mechanism 10, promote the yields of product.

Therefore, the elastic buffer parts 14 are arranged between the baffle plates 13 and the supports 11, so that after the two baffle plates 13 move to the limiting positions, when the two supports 11 continue to move oppositely to drive the cutter 12 to cut, the elastic buffer parts 14 can be compressed, so that the two baffle plates 13 can be kept at the limiting positions, and the mutual impact between the two baffle plates 13 is reduced; in addition, when the two baffles 13 move away from each other, the elastic potential energy stored in the elastic buffer 14 helps to drive the baffles 13 to reset.

In some examples, the baffle 13 or the seat 11 has a receiving groove into which the elastomeric cushion 14 at least partially extends.

Thus, providing the accommodation groove for placing the elastic buffer 14 makes the arrangement of the entire cutting mechanism 10 more compact.

Of course, the utility model discloses be not limited to and adopt elastic buffer 14, elastic buffer 14 can continue to compress when moving to the continuous motion in opposite directions of limiting position after support 11 to make baffle 13 and the respective function mutually noninterfere of cutter 12, in other embodiments, baffle 13 can also be elastic deformation's plastic part, utilizes the deformation of baffle 13 self like this, so that support 11 can continue to move in opposite directions and drive cutter 12 and cut.

In some embodiments, each flap 13 has an abutment end which abuts against the other flap 13 when closed, and each cutter 12 has a cutting edge end, the distance between the abutment ends of the two flaps 13 being less than the distance between the cutting edge ends of the two cutters 12 when the two flaps 13 are not closed.

Therefore, the distance between the baffles 13 is smaller than that between the cutters 12, and before the cutters 12 close and cut the welding strips 60, the baffles 13 are closed, so that the welding strips 60 are effectively blocked.

In the embodiment shown in fig. 1, the solder ribbon cutting mechanism 10 further includes an air blowing member 15, the air blowing member 15 is connected to one of the holders 11, and the air blowing member 15 is located between the shutter 13 and the cutter 12 in the second direction.

As shown in fig. 1, an air supply member 15 is disposed between the baffle 13 and the cutter 12 on one side, one end of the air supply member 15 is connected to the support 11, the other end is an air outlet with a certain angle, the air outlet faces the side of the welding strip 60 slightly inclined to the baffle 13, and the air outlet of the air supply member 15 is higher than the blade end of the cutter 12.

Therefore, the air supply part 15 connected with the support 11 can provide traction force for the cut solder strip head, guide the solder strip head to move towards the position of the baffle 13, and the air outlet with an angle can blow the solder strip 60 to a designated area.

In some embodiments, the solder ribbon cutting mechanism 10 further includes a collection box 16 disposed on the other support 11, the collection box 16 being located between the baffle 13 and the cutter 12 in the second direction, the collection box 16 having an open inlet opening facing the air outlet of the air blowing member 15 in an opposite direction.

That is, a collecting box 16 is arranged between the baffle 13 and the cutter 12 on the other support 11, the inlet of the collecting box 16 is arranged upward, the air outlet of the air blowing member 15 is arranged downward, the inlet of the collecting box 16 and the air outlet of the air blowing member 15 are not limited to be arranged oppositely up and down, and the inlet and the air outlet can be staggered by a certain distance in the feeding direction of the solder strip 60.

Therefore, the cut welding strips 60 are blown into the collecting box 16 through the air blowing piece 15, the arrangement of the collecting box 16 facilitates the collection of the welding strip heads, and the scattering of the welding strip heads on the welding strips 60 is reduced.

In some embodiments, the collection cassette 16 also has a suction port for connection to a negative pressure suction device to direct a flow of air from the inlet port to the suction port.

A suction port connected to a negative pressure suction device is provided in the collecting box 16 to form a negative pressure in the collecting box 16, so that the air blowing member 15 blows the solder ribbon head downward, and the collecting box 16 sucks the solder ribbon head downward to better guide the cut solder ribbon head to fall into the collecting box 16.

In some embodiments, the inlet of the collection cassette 16 is funnel-shaped, and the collection cassette 16 is removably attached to the support 11. Such as a collecting box 16, which is snapped, plugged or screwed onto the support 11.

Like this, the import is the infundibulate that one end cross-section is big, one end cross-section is little, and the design of flaring formula has increased the probability that the solder strip head got into and collects box 16 like this, and the inner wall of infundibulate can play the guide effect to the solder strip head that gets into and collect box 16 moreover. In addition, the removable collection box 16 facilitates the tipping of the weld head and also facilitates maintenance and replacement.
