Description

Technical Field

[0001] This utility model relates to the field of tension detection technology, and in particular to a diaphragm tension detection device. Background Technology

[0002] After production, the tension uniformity of the diaphragm needs to be tested. Currently, the test is usually conducted by having staff manually pull the diaphragm to provide the force. However, there are some shortcomings in providing the force by manually pulling the diaphragm, such as the instability of the force provided, which affects the test effect of the diaphragm tension. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to propose a diaphragm tension detection device to solve the problem that the applied force is unstable, which affects the detection effect of diaphragm tension uniformity.

[0004] To achieve the above objectives, this utility model provides a diaphragm tension detection device, including a frame, and further comprising: a support, a winding roller, a limiting part, a conveying assembly, a top frame, a laser rangefinder, a driving part, and a force-applying part, wherein:

[0005] The bracket is disposed on one side of the frame, the take-up roller is rotatably connected to the bracket, and the limiting part is disposed below the take-up roller to limit the rotation of the take-up roller;

[0006] The conveying assembly includes a first conveying roller, a second conveying roller, a third conveying roller, and a fourth conveying roller disposed on the frame;

[0007] The top frame is disposed above the frame, the laser rangefinder is slidably mounted on the top frame via a mounting plate, and the drive unit is connected to the laser rangefinder via a transmission connection.

[0008] The force-applying part includes a first clamping plate, a second clamping plate, and a support plate. The first clamping plate and the second clamping plate are detachably connected by bolts. The bottom of the second clamping plate is provided with a connecting strip, and the connecting strip has multiple through holes for hanging weights. The frame is provided with a sliding groove, and the support plate is slidably connected in the sliding groove for supporting the first clamping plate.

[0009] Optionally, the limiting part includes an electric cylinder disposed below the take-up roller, and a pressing plate is provided on the telescopic rod of the electric cylinder, the pressing plate being used to press the diaphragm on the take-up roller.

[0010] Optionally, the drive unit includes a lead screw rotatably connected to the top frame, one end of the lead screw being driven by a drive motor, and the lead screw being threadedly connected to the mounting plate.

[0011] Optionally, the distance between the third and fourth conveyor rollers is greater than 0.5 meters.

[0012] Optionally, the first, second, third, and fourth conveyor rollers are all detachably connected to the top of the frame by bolts.

[0013] When using this device to detect the tension of the diaphragm, the diaphragm is wound on the take-up roller and passes sequentially through the first, second, third, and fourth conveyor rollers. The diaphragm passes over the top of the third and fourth conveyor rollers, so that the diaphragm between the third and fourth conveyor rollers is in a horizontal state. The first end of the diaphragm is located between the first and second clamping plates. Then, the first and second clamping plates are fixed together to clamp the diaphragm. Then, according to the required force, a weight of appropriate weight is hung on the through hole. Then, the support plate is moved to separate the support plate from the first clamping plate, allowing the first and second clamping plates to fall freely. This applies a stable force to the diaphragm. Then, the drive unit moves the laser rangefinder to detect the diaphragm.

[0014] As can be seen from the above, this device can apply different stable forces by hanging weights of appropriate weight as needed, thereby improving the detection effect of diaphragm tension uniformity. Attached Figure Description

[0022] like Figures 1-2 As shown, a diaphragm 19 tension detection device includes a frame 1, and further includes: a support 2, a take-up roller 3, a limiting part, a conveying assembly, a top frame 4, a laser rangefinder 5, a drive part, and a force application part, wherein:

[0023] The bracket 2 is disposed on one side of the frame 1, the take-up roller 3 is rotatably connected to the bracket 2, and the limiting part is disposed below the take-up roller 3 to limit the rotation of the take-up roller 3;

[0024] The conveying assembly includes a first conveying roller 6, a second conveying roller 7, a third conveying roller 8, and a fourth conveying roller 9 disposed on the frame 1;

[0025] The top frame 4 is disposed above the frame 1, the laser rangefinder 5 is slidably disposed on the top frame 4 via the mounting plate 18, and the drive unit is connected to the laser rangefinder 5 in a transmission connection.

[0026] The force-applying part includes a first clamping plate 10, a second clamping plate 11, and a support plate 12. The first clamping plate 10 and the second clamping plate 11 are detachably connected by bolts. The bottom of the second clamping plate 11 is provided with a connecting strip 13. The connecting strip 13 has multiple through holes 14 for hanging weights. The frame 1 is provided with a sliding groove. The support plate 12 is slidably connected in the sliding groove and is used to support the first clamping plate 10.

[0027] When using this device to detect the tension of the diaphragm 19, the diaphragm 19 is wound on the take-up roller 3. The diaphragm 19 passes sequentially through the first conveyor roller 6, the second conveyor roller 7, the third conveyor roller 8, and the fourth conveyor roller 9. The diaphragm 19 passes over the top of the third conveyor roller 8 and the fourth conveyor roller 9, so that the diaphragm 19 between the third conveyor roller 8 and the fourth conveyor roller 9 is in a horizontal state. The first end of the diaphragm 19 is located between the first clamping plate 10 and the second clamping plate 11. Then, the first clamping plate 10 and the second clamping plate 11 are fixed together to clamp the diaphragm 19. Then, according to the required force, a weight of appropriate weight is hung on the through hole 14. Then, the support plate 12 is moved to separate the support plate 12 from the first clamping plate 10, so that the first clamping plate 10 and the second clamping plate 11 fall freely. In this way, a stable force is applied to the diaphragm 19. Then, the laser rangefinder 5 is moved by the drive unit to detect the diaphragm 19.

[0028] As can be seen from the above, this device can apply different stable forces as needed by hanging weights of appropriate weights, thereby improving the detection effect of the tension uniformity of the diaphragm 19.

[0029] In some embodiments, the limiting part includes an electric cylinder 15 disposed below the take-up roller 3, and a pressing plate 16 is provided on the telescopic rod of the electric cylinder 15. The pressing plate 16 is used to press the diaphragm 19 on the take-up roller 3.

[0030] When it is necessary to prevent the take-up roller 3 from rotating during the testing process, in order to prevent the take-up roller 3 from rotating, the electric cylinder 15 extends and drives the pressure plate 16 to move upward. After the pressure plate 16 contacts the diaphragm 19, it presses the diaphragm 19 to prevent the take-up roller 3 from rotating.

[0031] In some embodiments, the drive unit includes a lead screw 17 rotatably connected to the top frame 4, one end of which is connected to a drive motor, and the lead screw 17 is threadedly connected to the mounting plate 18. The drive motor rotates the lead screw 17, causing the mounting plate 18 to slide on the top frame 4, thereby moving the laser rangefinder 5. The laser rangefinder 5 determines the uniformity of the tension in the diaphragm 19 by measuring the distance.

[0032] In some embodiments, the distance between the third conveying roller 8 and the fourth conveying roller 9 is greater than 0.5 meters. This allows a larger surface of the diaphragm 19 to be flat, facilitating subsequent inspection.

[0033] In some embodiments, the first conveyor roller 6, the second conveyor roller 7, the third conveyor roller 8, and the fourth conveyor roller 9 are all detachably connected to the top of the frame 1 by bolts. This facilitates the maintenance and replacement of the first conveyor roller 6, the second conveyor roller 7, the third conveyor roller 8, and the fourth conveyor roller 9.
