[0021] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0022] like Figure 1-4 As shown, a stamping device with an alignment detection function comprises an alarm component 1, a detection mechanism, an upper die component and a lower die component arranged at the lower end of the upper die component, the lower die component comprises a lower die plate 2, the lower die plate 2 is provided with a receiving groove 21 for accommodating the detection mechanism, the detection mechanism comprises a positioning member 3, a support member 4 and a detection member 5 electrically connected to the alarm component 1, the upper end of the support member 4 protrudes out of the upper end surface of the lower die plate 2, the lower end of the support member 4 is placed in the receiving groove 21 and is slidably connected to the receiving groove 21, the upper end of the positioning member 3 protrudes out of the upper end surface of the support member 4 and is used to be inserted into the positioning hole 101 of the workpiece 10, that is, the height of the positioning member 3 protruding upward relative to the lower die plate 2 is higher than the height of the support member 4 protruding upward relative to the lower die plate 2, the lower end of the positioning column 32 is placed in the receiving groove 21 and is slidably connected to the receiving groove 21, one end of the detection member 5 is connected to the upper end of the support member 4, and the other end of the detection member 5 is used to abut against the outer wall of the positioning member 3 to sense the positioning member 3;

[0023] When the positioning member 3 fails to be inserted into the positioning hole 101 of the workpiece 10, the upper end of the positioning member 3 slides downward due to the pressure of the workpiece 10 until the outer wall of the positioning member 3 is separated from the detection member 5. The detection member 5 cannot sense the positioning member 3, and the alarm component 1 sounds an alarm.

[0024] The punching device with alignment detection function of the utility model has a simple structure and is easy to use. Compared with the prior art, a detection mechanism is provided to facilitate timely detection of misalignment between the workpiece 10 and the mold, thereby improving the punching efficiency and the punching accuracy. A positioning hole 101 is provided on the lower end surface of the workpiece 10, and the upper end of the positioning member 3 is used to be inserted into the positioning hole 101. The alarm component 1 is used to sound an alarm when the outer wall of the positioning member 3 is separated from the detection member 5, that is, the detection member 5 cannot sense the positioning column 32.

[0025] During use, the manipulator moves the workpiece 10 between the upper mold assembly and the lower mold assembly. When the upper end of the positioning member 3 can be inserted into the positioning hole 101 of the workpiece 10, that is, the workpiece 10 and the lower mold assembly are embedded with each other, at this time, the upper end face of the support member 4 abuts against the lower end face of the workpiece 10, and the end of the detection member 5 away from the support member 4 abuts against the outer wall of the positioning member 3. Under the pressure of the workpiece 10, the lower end of the support member 4 and the lower end of the positioning member 3 slide downward in the accommodating groove 21 synchronously, and drive the detection member 5 to move downward until the upper end face of the support member 4 is flush with the upper end face of the lower mold plate 2, that is, the support member 4 and the detection member 5 are both placed in the accommodating groove 21. During this process, the end of the detection member 5 away from the support member 4 always abuts against the outer wall of the lower end of the positioning member 3, and the alarm component 1 does not sound an alarm. When the positioning member 3 fails to be inserted into the positioning hole 101 of the workpiece 10, that is, the workpiece 10 and the lower mold assembly are misaligned, because the height of the positioning member 3 protruding upward relative to the lower mold plate 2 is higher than the height of the support member 4 protruding upward relative to the lower mold plate 2, the upper end of the positioning member 3 first slides downward under the pressure of the workpiece 10 until the outer wall of the positioning member 3 is separated from the detection member 5, the detection member 5 cannot sense the positioning member 3, and the alarm component 1 sounds an alarm. The operation is simple, and it is convenient for the operator to adjust the position between the workpiece 10 and the lower mold assembly in time according to the alarm of the alarm component 1 to achieve precise alignment.

[0026] Furthermore, the diameter of the upper end of the positioning member 3 is smaller than that of the lower end, and the end of the detection member 5 away from the support member 4 is used to abut against the outer wall of the lower end of the positioning member 3. Specifically, when the positioning member 3 fails to be inserted into the positioning hole 101 of the workpiece 10, that is, there is a misalignment between the workpiece 10 and the lower mold assembly, the upper end of the positioning member 3 first slides downward under the pressure of the workpiece 10, and the lower end of the positioning member 3 slides downward relative to the detection member 5, that is, the detection member 5 moves relative to the positioning member 3 and along the outer wall of the lower end of the positioning member 3 toward the outer wall of the upper end of the positioning member 3. When the end of the detection member 5 away from the support member 4 faces the upper end of the positioning member 3, there is a gap between the detection member 5 and the positioning member 3, and the alarm assembly 1 sounds an alarm.

[0027] It needs to be further explained that the lower mold assembly is provided with a plurality of inserts protruding upward from the upper end surface of the lower mold plate 2, the upper end of the support member 4 protrudes out of the upper end surface of the lower mold plate 2, and the height of the support member 4 protruding upward relative to the lower mold plate 2 is greater than the height of the insert protruding upward relative to the lower mold plate 2. This is to facilitate that when the positioning member 3 fails to be inserted into the positioning hole 101 of the workpiece 10, the workpiece 10 will first touch the support member 4 as the robot arm descends, and will not touch the insert protruding upward from the lower mold assembly, thereby avoiding damage to the insert and playing a warning role. The upper end of the positioning member 3 protrudes out of the upper end surface of the supporting member 4, so that when the positioning member 3 fails to be inserted into the positioning hole 101 of the workpiece 10, the workpiece 10 pushes the positioning member 3 to slide downward as the robot descends until the outer wall of the positioning member 3 is separated from the detecting member 5. Since the end of the detecting member 5 away from the positioning member 3 is connected to the upper end of the supporting member 4, that is, when the workpiece 10 is about to touch the insert protruding upward from the lower mold assembly, the alarm assembly 1 promptly sounds an alarm, thereby ensuring the safety of the workpiece 10 and the mold insert and improving the stamping efficiency.

[0028] Furthermore, the positioning member 3 includes a positioning block 31 and a positioning column 32 arranged at the lower end of the positioning block 31, the positioning block 31 is used to be inserted into the positioning hole 101 of the workpiece 10, the lower end of the positioning column 32 is placed in the receiving groove 21 and is slidably connected to the receiving groove 21, the diameter of the positioning block 31 is smaller than the diameter of the positioning column 32, and the end of the detection member 5 away from the support member 4 is used to abut against the outer wall of the positioning column 32 to sense the positioning column 32 to determine whether the positioning block 31 is inserted into the positioning hole 101 of the workpiece 10 and the alignment is accurate. Specifically, when the positioning block 31 can be inserted into the positioning hole 101 of the workpiece 10, under the pressure of the workpiece 10, the lower end of the support member 4 and the lower end of the positioning column 32 slide downward in the accommodating groove 21 synchronously, and drive the detection member 5 to move downward, until the upper end surface of the support member 4 and the upper end surface of the positioning column 32 are both flush with the upper end surface of the lower template 2. During this process, the end of the detection member 5 away from the support member 4 always rests on the outer wall of the positioning column 32, and the alarm component 1 does not sound an alarm. When the positioning block 31 fails to be inserted into the positioning hole 101 of the workpiece 10, the upper end of the positioning block 31 first slides downward under the pressure of the workpiece 10 until the outer wall of the positioning column 32 is separated from the detection member 5. During this process, the detection member 5 moves toward the positioning block 31 relative to the positioning column 32 and along the outer wall of the positioning column 32. When the end of the detection member 5 away from the support member 4 faces the positioning block 31, because the diameter of the positioning block 31 is smaller than the diameter of the positioning column 32, a gap is left between the detection member 5 and the positioning block 31, and the alarm component 1 sounds an alarm.

[0029] In this embodiment, the upper end of the positioning column 32 protrudes out of the upper end surface of the lower template 2, and the end of the detection member 5 away from the support member 4 is used to abut against the outer wall of the upper end of the positioning column 32, so as to facilitate the inspection of the positional relationship between the end of the detection member 5 away from the support member 4 and the positioning column 32, and facilitate timely adjustment to improve the stamping efficiency.

[0030] Furthermore, the detection mechanism also includes a first elastic member 6 placed in the receiving groove 21, the upper end of the first elastic member 6 is connected to the lower end of the support member 4, and the lower end of the first elastic member 6 is connected to the inner wall of the lower template 2. The first elastic member 6 is used to reduce the pressure of the workpiece 10 on the support member 4, and also provides a driving force for the support member 4 to slide upward along the groove wall of the receiving groove 21. Specifically, when the positioning block 31 is inserted into the positioning hole 101 of the workpiece 10, the product acts on the upper end of the support member 4, so that the support member 4 slides downward and compresses the first elastic member 6, and the first elastic member 6 generates an elastic restoring force to reduce the pressure of the workpiece 10 on the support member 4; when the pressure of the product on the upper end of the support member 4 disappears, the elastic restoring force of the first elastic member 6 causes the support member 4 to slide upward, and the support member 4 returns to its original position, and the operation is stable.

[0031] Furthermore, the detection mechanism also includes a second elastic member 7 placed in the receiving groove 21, the upper end of the second elastic member 7 is connected to the lower end of the positioning column 32, and the lower end of the second elastic member 7 is connected to the inner wall of the lower template 2. The second elastic member 7 is used to reduce the pressure of the workpiece 10 on the positioning column 32, and also provides a driving force for the positioning column 32 to slide upward along the groove wall of the receiving groove 21. Specifically, the product acts on the upper end of the positioning block 31, so that the positioning block 31 and the positioning column 32 slide downward to compress the second elastic member 7, and the second elastic member 7 generates an elastic restoring force to reduce the pressure of the workpiece 10 on the positioning column 32; when the pressure of the product on the upper end of the positioning block 31 disappears, the elastic restoring force of the second elastic member 7 causes the positioning column 32 to slide upward, and the positioning column 32 returns to its original position, and the operation is stable.

[0032] Furthermore, the detection mechanism further includes a limit block 8 placed in the accommodating groove 21, the limit block 8 extends a first extension arm 81 toward the support member 4, the support member 4 extends a second extension arm 41 toward the lower end of the first extension arm 81, the first extension arm 81 abuts against the second extension arm 41, and the structure is simple. The mutual cooperation between the first extension arm 81 and the second extension arm 41 makes it difficult for the support member 4 to separate from the lower template 2, thereby improving the safety performance of the stamping device.

[0033] Furthermore, the lower template 2 is provided with a mounting block 22 placed in the accommodating groove 21, and the positioning column 32 is passed through the mounting block 22 and is slidably connected to the mounting block 22. Specifically, the lower end of the positioning column 32 is passed through the mounting block 22 and is connected to the second elastic member 7, and the positioning column 32 is slidably connected to the mounting block 22. The mounting block 22 is used to install the positioning column 32 in the lower template 2 for easy assembly.

[0034] Further, the lower mold assembly includes a mold base 9 disposed at the lower end of the lower mold plate 2, the mold base 9 is provided with a second groove 92 and a first groove 91 both communicating with the accommodating groove 21, the lower end of the first elastic member 6 extends downward to the first groove 91, the first elastic member 6 is slidably connected to the first groove 91, the lower end of the second elastic member 7 extends downward to the second groove 92, the second elastic member 7 is slidably connected to the second groove 92. The first groove 91 and the second groove 92 separate the first elastic member 6 and the second elastic member 7, respectively, so that the first elastic member 6 and the second elastic member 7 are compressed and extended, respectively, and the operation is stable.

[0035] In this embodiment, the alarm component 1 is used to connect with an external device. Specifically, a wire groove is provided on the upper end surface of the mold base 9, which is connected to the first groove 91 and the second groove 92. The wire groove is used to install the wires of the alarm component 1. The wires of the alarm component 1 extend outward from the alarm component 1, and then the first line and the second line are separated by the wire groove. The first line passes through the first groove 91 and the receiving groove 21 in turn and passes through the support member 4 and is connected to the detection member 5. The second line passes through the second groove 92 and the receiving groove 21 in turn and is connected to the positioning column 32. In this arrangement, when the end of the detection member 5 away from the support member 4 abuts against the outer wall of the positioning column 32, the first circuit and the second circuit form a closed loop, that is, the positioning column 32, the detection member 5 and the alarm component 1 form a closed loop, and the alarm component 1 does not sound an alarm, that is, the alarm component 1 determines whether the end of the detection member 5 away from the support member 4 abuts against the outer wall of the positioning column 32 based on whether the first circuit and the second circuit form a closed loop, thereby determining whether the positioning block 31 is inserted into the positioning hole 101 of the workpiece 10. The structure is simple and easy to assemble.
