In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the protection scope required by the present application.

[0036] In the automatic stamping process, the next workpiece is usually fed after the previous workpiece is completed and taken away by the manipulator, but in actual production process, the next workpiece may be fed without waiting for the previous workpiece to be taken away, so that the stamping die may prevent at least two workpieces in the same stamping position from being stamped at the same time, that is, double pieces.

[0037] In order to prevent the occurrence of stamping at least two plates placed in the same stamping position, in some related technologies, a sensor is installed on the die. In order not to affect the stamping process and to be able to sense the workpiece placed on the lower die, a sensor is usually installed on the lower die, when the sensor senses that the workpiece is still placed on the lower die, the signal is sent to the control module to control the feeding mechanism to stop feeding the workpiece; when the sensor cannot sense the workpiece on the lower die, the feeding mechanism can be controlled to feed the workpiece to the lower die. However, the sensor in the related art is usually fixed, and the sensor can only detect the workpiece within a certain distance range, if the workpiece is placed at a higher position, the sensor may not be able to sense the workpiece and there is a risk of misjudgment.

[0038] In order to reduce the risk of misjudgment of the sensor, the present application provides a sensing positioning device.

[0039] Please refer to Figures 1 to 3 In an embodiment of the present application, the sensing positioning device comprises a fixing seat 100, a supporting adjusting mechanism 200, a sensing assembly 300 and a limiting piece 400; the supporting adjusting mechanism 200 is in transmission connection with the sensing assembly 300 and can drive the sensing assembly 300 to move in a first direction; the limiting piece 400 is adjustably connected to the fixing seat 100 in the first direction and can limit the sensing assembly 300 in the first direction.

[0040] The support adjusting mechanism 200 is a mechanism for supporting the sensing assembly 300 and adjusting the position of the sensing assembly 300 in the first direction. The support adjusting mechanism 200 can be a support spring, a gas cylinder, a screw nut assembly, or a gear ruler assembly, etc. The first direction can be upward, downward, leftward, rightward, forward, or backward, etc., and is specifically the direction of the sensing assembly 300 towards the workpiece. It can be understood that when the sensing positioning device is applied to a mold, and the movable mold is arranged above the fixed mold, the sensing positioning device can be specifically installed on the lower mold of the mold, and the support adjusting mechanism 200 can adjust the position of the sensing assembly 300 in the upward direction. Of course, the sensing positioning device can also be used in other machining equipment, as long as the sensing positioning device can timely adjust the position of the sensing assembly 300 according to the placement accuracy of the workpiece to reduce the risk of misjudgment. For example, in other machining equipment, the sensing positioning device can be arranged on the left side or the right side of the workpiece, at which time the support adjusting mechanism 200 can be timely adjusted to adjust the position of the sensing assembly 300 in the left-right direction. Alternatively, in other machining equipment, the sensing positioning device can be arranged on the front side or the back side of the workpiece, at which time the support adjusting mechanism 200 can be timely adjusted to adjust the position of the sensing assembly 300 in the front-back direction.

[0041] When the limiting piece 400 is adjustably connected to the fixing base 100 in the first direction, specifically, the limiting piece 400 or the fixing base 100 is provided with a plurality of connecting holes 120 in the first direction, and the limiting piece 400 is detachably connected to the fixing base 100 to selectively connect with different connecting holes 120, so as to adjust the position of the limiting piece 400 in the first direction, and to limit the inductive assembly 300 in different positions in the first direction. Alternatively, the limiting piece 400 can be slidably arranged on the fixing base 100, and the limiting piece 400 is provided with a plurality of first insertion holes and the fixing base 100 is provided with a plurality of second insertion holes, when the limiting piece 400 is adjusted to the right position on the fixing base 100, a pin can be inserted into a corresponding first insertion hole and a corresponding second insertion hole, so as to realize the positioning effect of the limiting piece 400, and to realize the stable limiting effect of the inductive assembly 300. Alternatively, the fixing base 100 is provided with a mounting groove, and a elastic limiting assembly is mounted in the mounting groove, the elastic limiting assembly includes an elastic piece and a ball connected to the elastic piece, wherein the elastic piece is located in the mounting groove, and a part of the ball is located in the mounting groove and another part of the ball extends out of the mounting groove; the limiting piece 400 is provided with a plurality of positioning holes arranged in the first direction, and when the limiting piece 400 moves in the first direction, the ball can be clamped into different positioning holes, thereby realizing the effect that the limiting piece 400 can be fixed in different positions in the first direction. When the inductive assembly 300 is adjusted in the up-down direction, the limiting piece 400 can be arranged above the inductive assembly 300, thereby limiting the risk of over-adjustment of the inductive assembly 300 under the driving action of the support adjusting mechanism 200, and reducing the risk of damage of the inductive assembly 300 by the workpiece. The limiting piece 400 can be a plate-shaped body, a block-shaped body or a rod-shaped body, etc.

[0042] The technical scheme of the present application can drive the inductive assembly 300 to move in the first direction by driving connection between the support adjusting mechanism 200 and the inductive assembly 300, so as to adjust the position of the inductive assembly 300 in the first direction, so that the inductive assembly 300 can adjust the distance between the inductive assembly 300 and the workpiece in time according to the position of the workpiece, thereby reducing the risk of misjudgment due to the inductive assembly 300 failing to sense the workpiece. In addition, the limiting piece 400 is adjustably connected to the fixing base 100 in the first direction, and can limit the inductive assembly 300 in the first direction, so as to adjust the position of the limiting piece 400 in the first direction, thereby adapting to effectively limit the inductive assembly 300 in different positions, and reducing the risk of damage of the inductive assembly 300 by the workpiece due to over-adjustment by the support adjusting mechanism 200.

[0043] As Figure 1As shown, in some embodiments of this application, the limiting member 400 includes a connecting portion 410 and an extension arm 420. The connecting portion 410 is adjustablely connected to the fixed base 100 in a first direction; the extension arm 420 is connected to the connecting portion 410 and is opposite to the sensing component 300, and limits the sensing component 300 in the first direction.

[0044] When the connecting part 410 is adjustablely connected to the fixed base 100 in the first direction, the structure of connecting the limiting member 400 to the fixed base 100 described above can be adopted, which will not be described in detail here. The connecting part 410 can be a connecting plate, connecting strip, connecting rod, or connecting block, etc.

[0045] The extension arm 420 is connected to the connecting part 410 and faces the sensing component 300, limiting the sensing component 300 in a first direction. The sensing component 300 may include a main body and a stop portion disposed on the main body that mutually limits the extension arm 420. The stop portion may be block-shaped, columnar, or other shaped, as long as it can be limited by the extension arm 420 when it moves along the first direction with the main body of the sensing component 300. Taking an upward direction as an example, the sensing component 300 can move upward under the action of the support adjustment mechanism 200. The extension arm 420 of the limiting member 400 can be disposed above the stop portion in the sensing component 300 to limit the upward movement of the stop portion.

[0046] By including a connecting portion 410 and an extension arm 420 in the limiting member 400, with the connecting portion 410 adjustablely connected to the fixed base 100 in the first direction and the extension arm 420 connected to the connecting portion 410, the extension arm 420 can also change position in the first direction along with the connecting portion 410 when the connection position of the connecting portion 410 with the fixed base 100 changes. This allows the extension arm 420 to adapt to the movement of the sensing component 300 to different positions in the first direction and effectively limit its movement. Furthermore, this configuration results in a smaller size and lower cost for the limiting member 400.

[0047] like Figure 1 As shown, in some embodiments of this application, one of the connecting part 410 and the fixed base 100 is provided with an elongated adjustment hole 411, which extends along a first direction, and the other is provided with a connecting hole 120; the sensing positioning device also includes a fastener 500, which passes through the adjustment hole 411 and the connecting hole 120, and fixes the limiting member 400 to the fixed base 100.

[0048] Specifically, the connecting portion 410 is provided with a long strip-shaped adjusting hole 411, and the fixing seat 100 is provided with a connecting hole 120; or the connecting portion 410 is provided with the connecting hole 120, and the fixing seat 100 is provided with the long strip-shaped adjusting hole 411. The long strip-shaped adjusting hole 411 can be a waist-shaped hole or a rectangular hole, etc. The connecting hole 120 can be a circular hole or a long strip-shaped hole. The fastener 500 can be a screw or a bolt, etc.

[0049] By providing the long strip-shaped adjusting hole 411 on one of the connecting portion 410 and the fixing seat 100, and providing the connecting hole 120 on the other one, and then penetrating the fastener 500 through the adjusting hole 411 and the connecting hole 120 to fix and connect the limiting piece 400 to the fixing seat 100, on one hand, the stable connecting effect of the connecting portion 410 and the fixing seat 100 can be ensured, and on the other hand, the stepless adjusting effect of the installation position of the connecting portion 410 on the fixing seat 100 along the first direction can be realized.

[0050] Please refer to Figure 2 and Figure 3 In some embodiments of the present application, the support adjusting mechanism 200 is an elastic support mechanism, which extends along the first direction and elastically supports the sensing assembly 300.

[0054] The elastic member can be a spring or a spring piece. The cross-sectional shape of the guide groove 312 can be circular, rectangular or other special-shaped, etc. The end of the elastic member extending out of the guide groove 312 away from the first direction can abut or be fixedly connected to a base 600, so as to provide good support effect for the elastic member.

[0055] By setting the guide groove 312 on the induction assembly 300, one end of the elastic member extends into the guide groove 312, and the other end extends out of the guide groove 312 away from the first direction, so that the elastic member can be more stable in the first direction. The risk of elastic member skew is reduced.

[0056] Further, the elastic member can be provided with at least two in parallel, and the corresponding guide groove 312 is also provided with at least two, so as to improve the elastic support stability of the elastic support mechanism to the induction assembly 300.

Or one surface of the induction assembly 300 and the fixed seat 100 can be in sliding contact, so as to realize the sliding connection effect of the induction assembly 300 and the fixed seat 100.

[0059] By slidingly connecting the induction assembly 300 and the fixed seat 100, the induction assembly 300 and the fixed seat 100 have good connection effect, so as to reduce the risk of shaking of the induction assembly 300 when moving in the first direction under the drive of the support adjusting mechanism 200.

The cooperation of the sliding groove 110 and the sliding block 313 makes the induction assembly 300 have good guiding effect when sliding.

[0063] As shown in Figure 4 In some embodiments of the present application, the chute 110 has a bottom wall, and the opening area of the chute 110 away from the bottom wall is smaller than the opening area of the chute 110 close to the bottom wall.

[0064] Specifically, the chute 110 can be a T-shaped slot or a dovetail slot, etc. The slider 313 can correspond to a T-shaped slider 313 or a dovetail block, etc.

[0065] By making the opening area of the chute 110 away from the bottom wall smaller than the opening area of the chute 110 close to the bottom wall, the risk of the slider 313 easily falling out of the chute 110 in the vertical first direction can be reduced.
