[0018] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model. However, the present utility model is not limited to these embodiments.
[0019] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a reed switch automatic leg-cutting device includes a base 1. A first mounting plate 2 is vertically fixed at the middle position on the top of the base 1. An oscillating cylinder 21 is fixed on the upper part of one surface of the first mounting plate 2. A first cylinder 22 is fixed on the rotor of the oscillating cylinder 21. A second mounting plate 23 is fixed on the piston rod of the first cylinder 22. A second cylinder 24 is fixed on the second mounting plate 23. A sleeve 25 is sleeved outside the piston rod of the second cylinder 24, and one end of the sleeve 25 is threadedly connected to the cylinder block of the second cylinder 24. A material-taking port 26 is provided at the other end of the sleeve 25. A permanent magnet block 27 is fixed at the outer end of the piston rod of the second cylinder 24, and the permanent magnet block 27 can reciprocally slide in the sleeve 25 under the drive of the second cylinder 24. At the top end of the base 1, a first mounting bracket 3 and a second mounting bracket 4 are respectively fixed on both sides of the first mounting plate 2. Two baffles 31 made of aluminum alloy are spaced at the top of the first mounting bracket 3, and one end of each of the two baffles 31 close to the first mounting plate 2 is thinner than the other end. The two opposite surfaces of the two baffles 31 are parallel to each other, and step surfaces 32 are provided at the bottoms of the two opposite surfaces. Permanent magnet plates 33 are fixed on one of the two opposite surfaces of the two baffles 31. A shearing mechanism 41 is fixed at the top end of the second mounting bracket 4, and two cutting scissors 42 are spaced on the shearing mechanism 41. The oscillating cylinder 21 can drive the sleeve 25 to reciprocally swing within an interval of 180°. When the sleeve 25 swings to one extreme position, the material-taking port 26 is just aligned between the two baffles 31. When the sleeve 25 swings to the other extreme position, the material-taking port 26 is switched to between the two cutting scissors 42.
[0020] Working principle: When using this device to perform the pin-cutting operation on the reed switch 5, a large number of reed switches 5 can be horizontally placed between the two baffles 31. Since permanent magnet plates 33 are provided on the outer sides of both baffles 31 and the distance between the two baffles 31 is slightly greater than the length of the reed switch 5, each reed switch 5 is horizontally arranged between the two baffles 31 under the attraction at both ends. Then, the swing cylinder 21 operates to drive the first cylinder 22, the second cylinder 24, and the sleeve 25 to swing, making it in a horizontal state and stop, and aligning the material-taking port 26 thereon with the space between the two baffles 31. At the same time, the second cylinder 24 operates to drive the permanent magnet block 27 to extend forward to a position close to the material-taking port 26. Then, the first cylinder 22 operates to drive the second mounting plate 23 to extend forward, and further drive the entire second cylinder 24 and the sleeve 25 to extend forward, making the material-taking port 26 close to the reed switch 5. At this time, since the material-taking port 26 is semi-circular and its inner diameter slightly matches the outer diameter of the reed switch 5, only one reed switch 5 is adsorbed by the permanent magnet block 27 in the material-taking port 26. Then, the first cylinder 22 retracts to retract the sleeve 25 that has completed the material-taking. Then, the swing cylinder 21 operates again to drive the sleeve 25 to swing in the opposite direction. At this time, the pins at both ends of the reed switch 5 are exactly located in the two cutting scissors 42 respectively. Then, the shearing mechanism 41 operates to make the two cutting scissors 42 cut a part of the pins at both ends of the reed switch 5. Finally, the second cylinder 24 retracts to move the permanent magnet block 27 away from the reed switch 5, so that it loses the adsorption force and automatically drops into the plastic basket 6 below the cutting scissors 42. There is a control module in this device. We only need to burn the corresponding program in the control module, and it can automatically and orderly complete the above actions and repeat continuously, thus realizing the automatic pin-cutting operation on the reed switch 5.
[0021] As Figure 5 shown, since one end of the two baffles 31 of this device close to the first mounting plate 2 is thinner and the baffle 31 is made of aluminum alloy, the end of the reed switch 5 close to the thinner end of the baffle 31 is closer to the permanent magnet plate 33, that is, the magnetic field is stronger at the thinner end, and the greater the attraction of the permanent magnet plate 33 to the reed switch 5. In addition, since the two permanent magnet plates 33 are inclined and symmetrically arranged, their attraction to the reed switch 5 will also be inclined accordingly (as shown by the arrows in Figure 5 ). Therefore, after the front reed switch 5 is taken away by the sleeve 25, the reed switch 5 behind it will automatically move forward under the action of the magnetic field. In this way, the orderly arrangement of the reed switches 5 can be realized without any mechanical structure and action, waiting to be taken by the sleeve 25. Step surfaces 32 are provided at the lower parts of the two opposite surfaces of the two baffles 31, which can prevent the reed switch 5 from falling. At the same time, the pins at both ends of the reed switch 5 at the lowermost position are always supported by the step surfaces 32, so as to limit it in the vertical direction, facilitating the sleeve 25 to adsorb and take it.
[0022] The structure of this device is simple. Especially for the arrangement and feeding of the reed switches 5, only by relying on two inclined and symmetrically arranged permanent magnet plates 33 can the automatic orderly arrangement of the reed switches 5 be realized, and then the automatic feeding can be achieved. It has a high degree of automation and low cost.
[0023] As Figure 1 , Figure 2 and Figure 3 , a chute 34 is provided at the top of the first mounting frame 3, and each baffle 31 is detachably mounted at the top of the first mounting frame 3 through the chute 34. By using the chute 34 to install the two baffles 31, the distance between the two baffles 31 can be adaptively adjusted according to the length of the reed switches 5 purchased, so that the applicability of this device is more extensive.
[0024] As Figure 1 , Figure 2 and Figure 3 , a pneumatic gripper 43 is fixed at the top of the shearing mechanism 41, and extension plates 44 extending downward are fixed on both clamping plates of the pneumatic gripper 43, and the lower ends of the two extension plates 44 both extend to the outside of the two cutting scissors 42; through holes are opened at the lower ends of the two extension plates 44, adjusting rods 45 are inserted into each through hole, a stop piece 46 is fixed at one end of each adjusting rod 45 close to the cutting scissors, and the distance between the stop piece 46 and the cutting scissors 42 can be adjusted by sliding each adjusting rod 45; locking bolts 47 are also provided on each extension plate 44, and each locking bolt 47 can lock the corresponding adjusting rod 45 in the corresponding through hole. After the reed switch 5 reaches the cutting scissors 42, the two clamping plates of the pneumatic gripper 43 act simultaneously, driving the two extension plates 44 to move towards the middle synchronously, thereby pushing the reed switch 5 to a central position, that is, after cutting, the lengths of the pins at both ends are the same. And the existence of the adjusting rod 45, the stop piece 46 and the locking bolt 47 enables us to adjust the position of the stop piece 46, and then adjust the cutting position again to make the cutting more accurate.
[0025] As Figure 5 shown, the magnetic poles of the two permanent magnet plates 33 are symmetrically arranged. For example, one opposite surface of the two permanent magnet plates 33 is an S pole, then the two reed pieces in the reed switch 5 are both N poles, that is, they repel each other and the reed switch 5 is not conducting. At the same time, the magnetic poles at the middle positions of each reed switch 5 are the same (S pole), so the adjacent reed switches 5 must repel each other, and then automatically disperse, making the subsequent taking more accurate, avoiding the situation of taking multiple pieces at one time, and then ensuring the orderly progress of the subsequent shearing operation and making its operation stability higher.
