Description

Technical Field

[0001] The present application belongs to the field of laser processing technology, and more specifically, relates to a thickness measuring device and detection equipment. Background Art

[0002] During battery production, the thickness of battery cells needs to be measured. This method typically involves placing the cell flat on a measuring platform, pressing down on the top surface with an electric cylinder, and measuring the thickness with a distance meter. However, this method requires a robotic arm to grab the cell from a transport and place it on the measuring platform. After the thickness measurement is complete, the robotic arm must reposition the cell on the transport before another cell can be picked up and placed on the measuring platform. This results in inefficient cell thickness measurement and impacts production schedules. Utility Model Content

Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0032] See also Figure 1 and Figure 2 The thickness measuring device provided in the embodiment of the present application is now described. The thickness measuring device provided in the embodiment of the present application includes a transport component 1, a first distance measuring component 2 and a second distance measuring component 3.

[0033] The transport component 1 is used to transport workpieces. The first distance measuring component 2 and the second distance measuring component 3 are respectively arranged on both sides of the transport component 1. The first distance measuring component 2 includes a first abutting distance measuring component 21, and the second distance measuring component 3 includes a second abutting distance measuring component 31 and an adjusting mounting component 32. The first abutting distance measuring component 21 and the second abutting distance measuring component 31 respectively abut against the opposite sides of the workpiece to detect the thickness of the workpiece. The second abutting distance measuring component 31 is installed on the adjusting mounting component 32. The adjusting mounting component 32 is used to adjust the angle of the second abutting distance measuring component 31 so that the side of the second abutting distance measuring component 31 in contact with the workpiece is parallel to the side of the workpiece facing the second abutting distance measuring component 31.

[0034] The workpiece in the embodiment of the present application may be a square battery cell or a finished battery, and may also be other workpieces that require thickness measurement.

[0035] The transport component 1 can be a conveyor belt, on which the workpiece is placed to be moved from one workstation to another. The transport component 1 can also be an electric module or other transport device.

[0036] The first abutting distance measuring member 21 may specifically be a fixed plate provided on one side of the transport component 1 .

[0037] The second abutment distance measuring member 31 may include a motor, an abutment plate and a grating ruler. The motor is connected to the abutment plate to drive the abutment plate to move toward or away from the side of the workpiece. The grating ruler is connected to the abutment plate to measure the movement distance of the abutment plate.

[0038] When the workpiece runs between the first abutting distance measuring member 21 and the second abutting distance measuring member 31, the second abutting distance measuring member 31 moves toward the first abutting distance measuring member 21, pushing the workpiece toward the first abutting distance measuring member 21, so that the two sides of the workpiece abut against the first abutting distance measuring member 21 and the second abutting distance measuring member 31 respectively, and the distance between the first abutting distance measuring member 21 and the second abutting distance measuring member 31 is the thickness of the workpiece.

[0039] The adjusting mounting member 32 may specifically be a rotating driving member that is transmission-connected to the second abutting distance-measuring member 31 . The rotating driving member may be a rotating cylinder or a rotating motor.

[0040] When measuring the thickness of a workpiece in the embodiment of the present application, the measurement can be performed directly on the transport device without moving the workpiece out of the transport device, thereby improving the efficiency of measuring the thickness of the workpiece and meeting the requirements of the production rhythm.

[0041] In addition, the adjusting mounting member 32 can adjust the angle of the second abutting distance measuring member 31 so that the side of the second abutting distance measuring member 31 in contact with the workpiece is parallel to the side of the workpiece facing the second abutting distance measuring member 31, thereby improving the accuracy of workpiece thickness measurement.

[0042] See also Figure 3 The adjusting mounting member 32 includes a mounting portion 321 and an adjusting portion. The second abutting and distance measuring member 31 is mounted on the mounting portion 321. The mounting portion 321 is connected to the adjusting portion. The adjusting portion is used to adjust the angle of the mounting portion 321 so that the side of the second abutting and distance measuring member 31 in contact with the workpiece is parallel to the side of the workpiece facing the second abutting and distance measuring member 31.

[0043] The mounting portion 321 may include a mounting base and a support frame. The support frame is used to support the second abutting and distance-measuring member 31. The side of the support frame opposite the first abutting and distance-measuring member 21 is perpendicular to the mounting base. The mounting portion 321 supports the second abutting and distance-measuring member 31, preventing the adjustment portion from directly contacting the second abutting and distance-measuring member 31 and potentially damaging it.

[0044] The adjusting mounting member 32 may specifically be a rotating driving member that is transmission-connected to the mounting portion 321 , and the rotating driving member may be a rotating cylinder or a rotating motor.

[0045] The adjusting portion may include a fixing portion and an arc-shaped adjusting hole 322 . The arc-shaped adjusting hole 322 is provided on the mounting portion 321 . The fixing portion is inserted into the arc-shaped adjusting hole 322 to fix the angle of the mounting portion 321 .

[0046] The first distance measuring assembly 2 and the second distance measuring assembly 3 can be mounted on workbenches on both sides of the transport assembly 1. The fixing portion can be a bolt or a screw, and the arc-shaped adjustment hole 322 can be an arc-shaped waist-shaped hole. The workbench is provided with mounting holes. The fixing portion is provided through the arc-shaped adjustment hole 322 on the mounting portion 321 and is threadedly connected to the mounting hole on the workbench.

[0047] Loosen the fixing part and rotate the mounting part 321 along the curvature direction of the arc-shaped adjustment hole 322 so that the side of the second abutting distance measuring part 31 in contact with the workpiece is parallel to the side of the workpiece facing the second abutting distance measuring part 31, and then tighten the fixing part so that the head of the fixing part abuts against the edge of the arc-shaped adjustment hole 322 to fix the mounting part 321.

[0048] Compared with providing the driving member rotation installation portion 321 , the fixing portion and the arc-shaped adjustment hole 322 have lower costs and occupy less space.

[0049] In addition, the adjustment part can also include a first adjustment sub-part and a second adjustment sub-part. The first adjustment sub-part and the second adjustment sub-part are spaced apart on the side of the mounting part 321 away from the workpiece or facing the workpiece. The first adjustment sub-part includes a mounting sub-part and an adjustment rod. The adjustment rod is installed on the mounting sub-part, and the adjustment rod is abutted against the mounting part 321.

[0050] The adjustment rod can be threadedly connected to the mounting sub-section, and the second adjustment sub-section can adopt the same structure as the first adjustment sub-section. To adjust the angle of the mounting section 321, simply rotate the adjustment rods on the first and second adjustment sub-sections until the surface of the second abutting distance-measuring member 31 in contact with the workpiece is parallel to the surface of the workpiece facing the second abutting distance-measuring member 31.

[0051] Compared with providing the driving member rotation mounting portion 321 , the cost of installing the secondary portion and the adjusting rod is lower.

[0052] Preferably, the second abutment and distance measuring member 31 includes a driving part 311, an abutment part 312 and a distance measuring part. The driving part 311 is transmission-connected to the abutment part 312 to drive the abutment part 312 to approach or move away from the workpiece. The abutment part 312 is used to abut against the side of the workpiece. The distance measuring part is used to detect the distance between the abutment part 312 and the first abutment and distance measuring member 21 to detect the thickness of the workpiece.

[0053] The distance measuring unit can be a laser rangefinder or an ultrasonic rangefinder. The driving unit 311 can be a pneumatic cylinder, an electric cylinder or a linear motor.

[0054] The second abutting distance measuring member 31 further includes a pressure detecting portion 314 , which is connected to the abutting portion 312 . The pressure detecting portion 314 is used to detect the pressure value between the abutting portion 312 and the side surface of the workpiece.

[0055] The pressure detection unit 314 may include a pressure sensor and a pressure digital display. The pressure digital display is electrically or signal-connected to the pressure sensor, which is connected to the abutment portion 312. The pressure sensor measures the actual pressure between the abutment portion 312 and the side of the workpiece, and the pressure digital display displays the actual pressure value. When the actual pressure value measured by the pressure sensor is within a preset pressure range, the driving unit 311 stops driving the abutment portion 312 toward the workpiece to prevent the abutment portion 312 from damaging the workpiece.

[0056] The second abutting distance measuring member 31 further includes a guiding portion 315 , which is connected to the abutting portion 312 to guide the abutting portion 312 .

[0057] The guide portion 315 may include a bearing and a guide column. The bearing is mounted on the mounting portion 321 . The guide column passes through the bearing on the mounting portion 321 and is connected to the abutting portion 312 .

[0058] The guide portion 315 may further include a slide rail and a slider. The slide rail is mounted on the mounting portion 321 . The length direction of the slide rail is parallel to the moving direction of the abutting portion 312 . The slide rail and the slider are slidably connected. The slider is connected to the abutting portion 312 .

[0059] The guide portion 315 can prevent the abutting portion 312 from being angularly deflected during the movement, and the guide portion 315 can ensure that the abutting portion 312 is parallel to the side surface of the workpiece after the movement.

[0060] The second abutting distance measuring member 31 further includes a stroke detecting portion 316 , which is configured to detect a moving distance of the abutting portion 312 .

[0061] The travel detection unit 316 can be a photoelectric sensor or a grating ruler. When the travel detection unit 316 detects that the movement distance of the abutting portion 312 reaches a preset value, the driving unit 311 stops driving the abutting portion 312 to move, preventing the movement distance of the abutting portion 312 from exceeding the preset value and causing damage to the workpiece.

[0062] An insulating layer is provided on a surface of the contact portion 312 that contacts the workpiece.

[0063] The insulating layer prevents the workpiece from coming into contact with metal materials on other components, which could cause a short circuit in the workpiece.

[0064] The first distance measuring component 2 can adopt the same structure as the second distance measuring component 3 .

[0065] An embodiment of the present application further provides a detection device, including the above thickness measuring device.

[0066] Since the detection equipment of the embodiment of the present application includes the thickness measuring device in any of the above embodiments, it has the beneficial effects brought by the thickness measuring device in any of the above embodiments, which will not be described in detail here.

[0067] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
