Technical Field

[0001] This utility model relates to the field of foil flatness detection devices, and in particular to an online foil flatness detection device based on line laser. Background Technology

[0002] In the production process of foil materials, surface flatness is one of the key indicators for measuring product quality. Traditional flatness testing methods mostly involve manual sampling or offline testing using fixed sensors.

[0003] However, the above-mentioned technologies have at least the following technical problems: In different foil manufacturing equipment, the inclination angle of the plane where the foil is located in the detection section is different. The fixed detection element cannot always be directly facing the surface of the foil being measured, which will lead to the distortion of measurement data and affect the detection accuracy. Utility Model Content

[0004] The purpose of this invention is to provide an online foil flatness detection device based on line laser, so as to solve the problem that the fixed detection elements in the prior art cannot be compatible with different foil manufacturing equipment.

Any one of the detection elements can reciprocate relative to the base frame along the first direction under the drive of the detection driver. The detection element is connected to the base frame via an adjustment assembly, which includes a first adjustment module and a second adjustment module. The first adjustment module has a first adjustment end that can swing around an axis parallel to a first direction, and the detection element is directly or indirectly connected to the first adjustment end. The second adjustment module has a second adjustment end that can move perpendicular to the first direction, and the detection element is directly or indirectly connected to the second adjustment end.

[0014] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1 and Figure 2 As shown, an online foil flatness detection device based on line laser includes a base frame 1 and detection elements 2. Multiple detection elements 2 are arranged in parallel on the base frame 1 along a first direction, and any detection element 2 can reciprocate relative to the base frame 1 along the first direction under the drive of a detection driver 7. In this embodiment, the detection element 2 is a laser displacement sensor, and the detection driver 7 consists of a servo motor and a lead screw mechanism.

[0015] In the application scenarios of this application, foil materials such as aluminum foil and copper foil pass over multiple detection elements 2 along a second direction perpendicular to the first direction under the drive of an external driving device. Combined with the reciprocating motion of the detection elements 2 along the first direction with the detection driver 7, the multiple detection elements 2 can measure the distance of the foil surface, thereby calculating the flatness of the foil surface based on the reading of the detection elements 2.

[0016] To enable multiple detection elements 2 to detect the flatness of foils with different incoming angles, in this embodiment, the detection elements 2 are connected to the base frame 1 via an adjustment assembly, which includes a first adjustment module 31 and a second adjustment module 32. Combined with... Figure 3 and Figure 4 As shown, the first adjustment module 31 has a first adjustment end 311 capable of swinging around an axis parallel to the first direction, and the detection element 2 is directly connected to the first adjustment end 311; the second adjustment module 32 has a second adjustment end 321 capable of operating perpendicular to the first direction, and the first adjustment module 31 is placed on the second adjustment end 321. In other embodiments of this application, the detection element 2 can also be indirectly connected to the first adjustment end 311 through the second adjustment module 32. When the portion of the foil being detected passes through multiple detection elements 2 with an inclined plane, the first adjustment module 31 can be adjusted to make the multiple detection elements 2 swing around an axis, so that their detection ends are facing the surface of the foil, and the distance between the detection ends of the detection elements 2 and the foil is consistent before and after adjustment, in conjunction with the second adjustment end 321.

[0017] The first adjustment module 31 includes a first adjustment body 312 fixed to the second adjustment end 321, the first adjustment end 311 being rotatably mounted on the first adjustment body 312, and multiple detection elements 2 being fixed to the first adjustment end 311 via a detection mounting plate 4. The second adjustment module 32 includes a second adjustment body 322 fixed to the execution end of the detection driver 7, and the second adjustment end 321 being slidably mounted on the second adjustment body 322.

[0018] Specifically, the first adjusting end 311 is radially provided with an adjusting paddle 313, and the first adjusting body 312 is provided with an adjusting base 314 corresponding to the adjusting paddle 313. The adjusting base 314 is threadedly fitted with an adjusting drive rod 315 and is provided with an elastic push rod 316. The adjusting drive rod 315 abuts against one side of the adjusting paddle 313, and the elastic push rod 316 abuts against the other side of the adjusting paddle 313. By rotating the adjusting drive rod 315, the adjusting paddle 313 is moved, thereby driving the first adjusting end 311 to rotate. When the adjusting drive rod 315 is rotated in the opposite direction, the elastic push rod 316 simultaneously drives the adjusting paddle 313 in the opposite direction, so that the adjusting paddle 313 still slides against the end of the adjusting drive rod 315, realizing bidirectional rotation of the first adjusting end 311 relative to the first adjusting body 312.

[0019] Furthermore, to prevent the detection mounting plate 4 from bending due to gravity, at least one pair of first adjustment modules 31 are provided, with both ends of the detection mounting plate 4 respectively fixed to the first adjustment ends 311 of the pair of first adjustment modules 31. In addition, a weight-reducing groove 41 is provided in the middle of the detection mounting plate 4 to reduce the weight in the middle of the detection mounting plate 4 and further reduce the bending deformation.

[0020] In addition, such as Figure 1 As shown, a detection and calibration component 5 and a through-beam light curtain 6 are slidably mounted on the base frame 1 along a first direction. The detection and calibration component 5 is used to zero-calibrate the detection element 2. One end of the detection and calibration component 5 is slidably connected to the base frame 1 via a slide rail arranged along the first direction, and the other end extends towards the detection element 2. The through-beam light curtain 6 is arranged parallel to the detection driver 7 and is used to detect the presence or absence of incoming materials.

[0021] In this embodiment, such as Figure 2 As shown, the base frame 1 includes a driver mounting plate 11 and a bracket 12. The driver mounting plate 11 is used to mount the detection driver 7, and the bracket 12 is fixed to both sides of the driver mounting plate 11, making the driver mounting plate 11 suspended. A connection hole 13 is provided at one end of the bracket 12 that is not connected to the driver mounting plate 11. The base frame 1 can be fixed to the production line using fasteners that pass through the connection hole 13, allowing the detection element 2 to perform flatness detection on the foil during foil production.
