[0003] The existing method is to manually place the product on the inspection table and use a 3D laser camera for inspection. During the inspection process, the product needs to be moved multiple times. This inspection method not only has high equipment costs but also requires operators to cooperate with the inspection, which increases the operator's physical labor and operation steps, thereby increasing the time spent on a single inspection and reducing work efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a high-efficiency automatic flatness detection device, which not only reduces the equipment cost but also realizes automated detection and improves detection efficiency.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] The detection component includes a laser displacement sensor, a rotating central control platform and an electromagnet. A first connecting plate is provided below the table top of the detection platform. The laser displacement sensor is fixed to one side of the first connecting plate. The rotating central control platform is provided at the bottom of the first connecting plate. The electromagnet is fixed on the rotating surface of the rotating central control platform and is located at the bottom of the rotating central control platform.

[0008] In a preferred example, the present invention can be further configured as follows: a first telescopic motor is provided on the top of the detection platform, and an output end of the first telescopic motor passes through the middle surface of the detection platform and is fixed to the first connecting plate.

[0009] In a preferred example, the present invention can be further configured as follows: two sleeves are provided on the table top;

[0011] The first telescopic motor is located between the two guide rods.

[0012] In a preferred example, the present invention can be further configured as follows: the detection table is further provided with a clamping assembly;

[0013] The clamping assembly includes two clamping plates, each of which has a clamping groove on one side, and the end of the clamping groove close to the product passes through the corresponding clamping plate;

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] 1.

DETAILED DESCRIPTION

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1-Figure 3 As shown, the present invention discloses an efficient automatic flatness detection device, comprising a device body 1. The device body 1 comprises a detection platform 11, which comprises four columns and a table top disposed on top of the four columns. A first telescopic motor 3 is disposed on the top of the table top.

[0026] The output end of the first telescopic motor 3 passes through the surface of the inspection platform 11 and is connected to a first connecting plate 24. Two guide rods 32 are symmetrically mounted on top of the first connecting plate 24. Two sleeves 31 extend through the surface of the inspection platform, and the guide rods 32 extend through corresponding sleeves 31, forming a sliding connection between the sleeves 31 and the guide rods 32. The first telescopic motor 3 is located between the two guide rods 32.

[0027] A detection assembly 2 is provided on the detection platform 11 . The detection assembly 2 includes a laser displacement sensor 21 , a rotating central control platform 22 and an electromagnet 23 .

[0028] The rotating central control platform 22 is arranged at the bottom of the first connecting plate 24 . The first connecting plate 24 is fixed to the fixed end of the rotating central control platform 22 . The electromagnetic sticker is fixed to the rotating end of the rotating central control platform 22 .

[0029] The laser displacement sensor 21 is fixed to one side of the first connecting plate 24. The light emitting end of the laser displacement sensor 21 points vertically downward. The rotating central control platform 22 rotates, driving the electromagnet 23. During this rotation, the electromagnet 23 does not collide with the light emitted from the laser displacement sensor 21.

[0030] A clamping assembly 4 is also provided on the testing platform 11 . The clamping assembly 4 includes two clamping plates 41 .

[0031] Two vertical plates 43 are symmetrically arranged on the outside of the testing platform 11. A sliding plate 5 is provided on each of the vertical plates 43 near the testing platform 11. A second telescopic motor 51 is horizontally passed through the sliding plate 5. The telescopic end of the second telescopic motor 51 passes through the corresponding sliding plate 5 and is fixed to the corresponding clamping plate 41.

[0032] A clamping groove 42 is formed on one side of each of the two clamping plates 41 , and the end of the clamping groove 42 close to the product passes through the corresponding clamping plate 41 .

[0033] Each vertical plate 43 is provided with a screw moving portion 6, wherein a moving block in the screw moving portion 6 is fixed to the corresponding sliding plate 5. The two clamping plates 41 are always at the same height.

[0034] A PLC controller (not shown) is provided on the outside of the device body 1. The PLC controller is electrically connected to the rotating central control platform 22, the laser displacement sensor 21, the electromagnet 23, the first telescopic motor 3, the second telescopic motor 51 and the screw moving part 6, and the PLC controller controls the actions of the rotating central control platform 22, the laser displacement sensor 21, the electromagnet 23, the first telescopic motor 3, the second telescopic motor 51 and the screw moving part 6 through a program.

[0035] The implementation principle of the above embodiment is:

[0036] When the product (with an iron round plate on the top of the cylinder) moves with the conveyor belt to the bottom of the electromagnet 23, the conveyor belt stops working. At this time, the product is placed in the fixture and the product generally maintains a vertical upward posture.

[0037] The PLC controller starts the two second telescopic devices at the same time, and the telescopic ends of the two second telescopic devices move toward the product at the same speed. When the product part is connected with the clamping groove 42 in the clamping plate 41, the two second telescopic devices stop moving.

[0038] The two clamping plates 41 play the role of correcting the position of the product. Since the product is placed in the jig, there is a certain gap between the inner hole wall of the jig and the product, and the product itself is slightly tilted.

[0039] Next, the PLC controller starts the first telescopic motor 3, and the telescopic rod in the first telescopic motor 3 moves downward, driving the first connecting plate 24 to move downward. When the electromagnet 23 contacts the iron plate on the top of the product, the first telescopic machine stops moving.

[0040] Next, the PLC starts the two second telescopic devices, causing the telescopic rods in the two second telescopic devices to move to the initial positions.

[0041] Next, the PLC starts the laser displacement sensor 21 and the rotating central control platform 22 simultaneously.

[0042] The rotating central control platform 22 drives the electromagnet 23 to rotate, and the electromagnet 23 drives the product to do circular motion. The light emitted by the laser displacement sensor 21 is irradiated on the iron plate on the top of the product. By collecting data at different positions on the iron plate and sending the data in the form of electrical signals to the computer terminal connected to the laser displacement sensor 21, rapid detection of the product can be achieved.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
