At the bottom end of the top shaft sleeve 23, there is an auxiliary disc 232 that can cooperate with the ejector rod 223. On one side of the driving shaft 21 away from the conveyor belt 3, there are fixed lead screws 24. The bottom ends of the fixed lead screws 24 are fixedly connected to the fixing plate 12, and the top ends of the fixed lead screws 24 are fixedly connected to the base 1. The fixed lead screws 24 all pass through the bent plate 213. On the top surface of the bent plate 213, there is a lifting shaft sleeve 241 rotatably connected and sleeved on the outside of the fixed lead screw 24. The top end of the lifting shaft sleeve 241 is connected to a lifting gear 242 that can mesh with the driving gear 231. The lifting shaft sleeve 241 cooperates with the fixed lead screw 24. When the lifting shaft sleeve 241 rotates, it can drive the bent plate 213 and the supporting plate 212 to perform reciprocating lifting movements.

[0025] See Figures 1 to 4, on the base 1 on the side of the driving shaft 21 close to the conveyor belt 3, vertical driven shafts 251 are rotatably provided.

The driven sliders 252 are all slidably connected to the fixing frame 25. On the surface of the driven shaft 251, a second reciprocating groove (its structure refers to the first reciprocating groove) is provided. The driven slider 252 cooperates with the second reciprocating groove (its cooperation mode refers to the switching slider 222 and the first reciprocating groove). In the middle of the base 1, an avoidance groove is provided. Two moving seats 26 are slidably provided in the avoidance groove. Between the adjacent moving seats 26 and the driven sliders 252, driven connecting rods 253 are provided (that is, one end of the driven connecting rod 253 is rotatably connected to the moving seat 26, and the other end of the driven connecting rod 253 is rotatably connected to the driven slider 252).

On the bottom surface of the mounting seats 271, retractable pressure detecting elements are provided (the pressure detecting elements are used to apply a certain magnitude of pressure to the metal plate and observe the bending condition of the metal plate. This is the prior art, so it will not be elaborated in the present invention). The bottom ends of the driven shafts 251 all pass through the base 1. On the driven shafts 251 below the base 1, top gears 254 capable of meshing with the driving gears 231 are provided. On the driven shafts 251 below the top gears 254, adjusting bushings are rotatably provided. On the bottom ends of the adjusting bushings, bottom gears 28 capable of meshing with the driving gears 231 are provided. On the adjusting bushings, adjusting sliders 281 are provided. On the surfaces of the adjusting bushings, third reciprocating grooves (its structure refers to the first reciprocating groove) are provided. The adjusting sliders 281 cooperate with the third reciprocating grooves (its cooperation mode refers to the switching slider 222 and the first reciprocating groove). A cross support plate 282 is connected between the two adjusting sliders 281. One end of each of the rotating lead screws 27 passes through the moving seat 26 and is connected to a turntable 272. On the turntables 272, eccentric rods 273 are provided. On the cross support plate 282, through grooves capable of cooperating with the eccentric rods 273 are provided. When the two adjusting sliders 281 perform synchronous reciprocating lifting motions, under the action of the through grooves and the eccentric rods 273, the turntables 272 can drive the rotating lead screws 27 to rotate unidirectionally. On the bottom surface of the base 1, pressing plates 29 corresponding to and cooperating with the supporting plates 212 one by one are provided, which can fix the ends of the metal plates to prevent the metal plates from falling off during detection.

[0026] See Figures 1 to 4 , preferably, both the fixed lead screw 24 and the rotating lead screw 27 are reciprocating lead screws.

[0027] See Figures 1 to 4 , preferably, on the top surface of the bending plate 213, a plurality of first limiting rods passing through the switching slider 222 are provided, and on the bottom surface of the base 1, a plurality of second limiting rods passing through the adjusting slider 281 are provided.

[0028] SeeFigures 1 to 4 , preferably, a bottom rod capable of cooperating with the mating slider 19 is provided on the bottom surface of the bent plate 213, so that the centering plate 13 can center the metal plate before the support plate 212 lifts the metal plate.

[0029] See Figures 1 to 4 , preferably, brackets 16 are provided on the support legs 11, and the guide shafts 15 are rotatably connected to the brackets 16, which can improve the stability of the device.

[0030] See Figures 1 to 4 , preferably, the driving member 211 is a rotary motor, which can provide sufficient power.

[0031] In the implementation process of the present invention: The conveyor belt 3 conveys the metal plate. When the metal plate is transported below the base 1, the conveyor belt 3 stops running, and the driving member 211 starts and rotates in reverse. At this time, the positive ratchet wheel does not cooperate with the positive ratchet pawl, and the reverse ratchet wheel cooperates with the reverse ratchet pawl. The bottom shaft sleeve 22 does not drive the rotating shaft sleeve 221 to rotate, and the top shaft sleeve 23 drives the driving gear 231 to rotate (at this time, the device is in the initial state, the support plate 212 is located below the metal plate, the first spring is in a compressed state, and the driving gear 231 meshes with the lifting gear 242). The driving gear 231 drives the lifting gear 242 to rotate. Under the cooperation of the lifting shaft sleeve 241 and the fixed lead screw 24, the bending plate 213 drives the support plate 212 to rise. Before the support plate 212 lifts the metal plate, the first spring restores its deformation, causing the fitting slider 19 to rise, thereby driving the two centering sliders 17 at the same end of the base 1 to move away from each other, causing the centering plate 13 to move towards the metal plate and push the metal plate to complete the centering of the metal plate. Then the support plate 212 lifts the metal plate until the top end of the metal plate abuts against the pressing plate 29. The support plate 212 and the pressing plate 29 cooperate to complete the fixation of the metal plate. Then the driving member 211 rotates forward. At this time, the positive ratchet wheel cooperates with the positive ratchet pawl, and the reverse ratchet wheel does not cooperate with the reverse ratchet pawl. The bottom shaft sleeve 22 drives the rotating shaft sleeve 221 to rotate, and the top shaft sleeve 23 does not drive the driving gear 231 to rotate. The rotating shaft sleeve 221 rotates to drive the switching slider 222 to move, so that the top shaft sleeve 23 moves relative to the bottom shaft sleeve 22, and the driving gear 231 disengages from the lifting gear 242 until the driving gear 231 meshes with the bottom gear 28. Then the driving member 211 rotates in reverse, causing the driving gear 231 to drive the bottom gear 28 to mesh, thereby driving the adjusting shaft sleeve to rotate. Under the action of the third reciprocating groove, the adjusting slider 281 performs reciprocating lifting motion. Under the cooperation of the eccentric rod 273 and the through groove, the rotating lead screw 27 rotates to change the position of the mounting seat 271 on the rotating lead screw 27. Then the driving member 211 rotates forward, causing the top shaft sleeve 23 to continue to rise until the driving gear 231 meshes with the top gear 254. Then the driving member 211 rotates in reverse, driving the driven shaft 251 to rotate. Under the action of the driven slider 252 and the driven connecting rod 253, the position of the moving seat 26 can be changed. During a single detection process, the user can adjust the position of the mounting seat 271 multiple times according to actual needs to achieve comprehensive detection.

[0032] The present invention provides a metal plate strength detection device, and its beneficial effects are as follows:

[0033] 1. By setting the detection component, it can not only realize the automatic picking and placing of the metal plate, reduce the labor intensity of the user, but also perform multi-point bending strength detection on the metal plate, expand the detection range, and ensure good detection effects and accuracy.

[0034] 2. By setting multiple centering plates, centering of the metal plate can be performed before lifting it, avoiding deflection of the metal plate during transportation, which may lead to abnormal picking, placing and detection, and further improving the detection accuracy.

[0035] In summary, the beneficial effects of the present invention are as follows: it can not only automatically pick and place the metal plate and perform multi-point detection, reducing the labor intensity and expanding the detection range, but also automatically center the metal plate, ensuring good detection accuracy.

[0036] Of course, the present invention may also have various embodiments.
