Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, and more specifically, to a laser marking machine. Background Technology

[0002] Laser marking technology, as a non-contact marking method, has been widely used in the field of industrial product identification, especially in high-precision and high-requirement marking scenarios where it has significant advantages. Membrane electrodes, as core components of new energy devices such as fuel cells, typically require QR codes or characters to be marked on their surfaces for product traceability, quality control, and anti-counterfeiting functions. In the production of precision materials such as membrane electrodes, flexible circuit boards, and optical films, the uniformity of material thickness directly affects product performance. For example, localized thickness deviations in fuel cell membrane electrodes can lead to uneven conductivity, affecting battery efficiency; abnormal thickness in lithium battery separators can even pose safety hazards. However, existing laser marking machines can only perform surface marking and cannot detect changes in material thickness, a parameter crucial to product quality. Furthermore, in current membrane electrode production processes, the thickness measurement and marking processes are independent, belonging to two different processes, resulting in slow production cycles and low production efficiency. Utility Model Content

[0003] Therefore, in order to solve the problem that the thickness measurement and marking processes of existing laser marking machines cannot be combined, this utility model provides a laser marking machine, the specific technical solution of which is as follows:

[0004] A laser marking machine includes a marking device, a thickness measuring device, and an adsorption platform for fixing a membrane electrode. The marking device includes a laser component that can slide relative to the adsorption platform, and a marking device is slidably mounted on the laser component. The thickness measuring device includes a sensing component that can slide relative to the adsorption platform. The sensing component includes a detector and a drive component for controlling the raising and lowering of the detector. The detector is provided with a contact plate and a detection head. The contact plate is connected to the detector by an elastic element and is used to abut against the surface of the membrane electrode. The contact plate has a detection hole for the detection head to reciprocate through. The marking device and the detector are both located above the adsorption platform.

[0005] The aforementioned laser marking machine incorporates an adsorption platform. The uniform negative pressure of the adsorption platform flattens the membrane electrode, ensuring a smooth processing surface and preventing laser defocusing or inconsistent marking depth due to unevenness. This also facilitates subsequent thickness measurement. A marking device marks QR codes and other markings on the membrane electrode surface without physical contact, avoiding damage to fragile materials. A detector measures the membrane electrode thickness in real time during the marking process, detecting areas that are too thin or too thick. A contact plate, designed to mechanically press against the flexible membrane electrode to force it into a flat state, provides a stable reference plane for the subsequent detection head, and eliminates thickness measurement errors caused by material deformation.

[0006] Furthermore, the laser marking machine also includes a control cabinet and a mounting cabinet located on one side of the control cabinet. The marking device is mounted on the top of the control cabinet, and a control power supply electrically connected to the marking device is installed inside the control cabinet. The thickness measuring device and the adsorption platform are both mounted on the top of the mounting cabinet.

[0007] Furthermore, the top of the control cabinet is provided with a first guide rail, and the top of the mounting cabinet is provided with a second guide rail, the setting direction of the first guide rail and the setting direction of the second guide rail being perpendicular to each other.

[0008] Furthermore, the adsorption platform is provided with a plurality of adsorption holes evenly distributed, and a negative pressure fan is installed at the bottom of the mounting cabinet, with the exhaust port of the negative pressure fan connected to the adsorption holes.

[0009] Furthermore, the laser assembly includes a connecting seat and a sliding seat slidably mounted on the first guide rail. The connecting seat is fixed to the top of the sliding seat, and a first transverse slide rail is provided on the connecting seat. One end of the coding device is slidably connected to the first transverse slide rail, and a coding dock is installed on the other end of the coding device.

[0010] Furthermore, the coding device also includes a first driving structure and a second driving structure. The first driving structure is mounted on the first guide rail and is used to control the sliding state of the sliding seat. The second driving structure is mounted on the first transverse slide rail and is used to control the sliding state of the coding device.

[0011] Furthermore, the sensing component also includes a sliding frame and a transverse base. The sliding frame is mounted on the second guide rail and can slide relative to the mounting cabinet. The sliding frame is provided with a second transverse slide rail. One end face of the transverse base is slidably mounted on the second transverse slide rail, and the other end face of the transverse base is provided with a lifting slide rail that is slidably connected to the detector.

[0012] Furthermore, the detector includes a lifting base, which is slidably connected to the lifting slide rail. One end of the elastic element is detachably connected to the bottom of the lifting base, and the other end of the elastic element is fixedly connected to the contact plate. The detection head is fixedly inserted on the lifting base, and the driving element is installed on the lifting slide rail and used to control the lifting state of the lifting base.

[0013] Furthermore, the elastic element includes a plug block, a compression block, and a return spring. The plug block is detachably inserted into the bottom of the lifting seat. The compression block is fixedly connected between the plug block and the contact plate. The return spring is wound around the compression block. One end of the return spring abuts against the bottom of the plug block, and the other end of the return spring abuts against the top of the contact plate.

[0014] Furthermore, the thickness measuring device also includes a third driving structure and a fourth driving structure. The third driving structure is mounted on the second guide rail and is used to control the sliding state of the sliding frame. The fourth driving structure is mounted on the second transverse slide rail and is used to control the sliding state of the transverse seat. Attached Figure Description

[0025] like Figures 1-4 As shown, a laser marking machine according to one embodiment of the present invention includes a marking device 1, a thickness measuring device 2, and an adsorption platform 3 for fixing a membrane electrode. The marking device 1 includes a laser component that can slide relative to the adsorption platform 3, and a marking device 11 is slidably mounted on the laser component. The thickness measuring device 2 includes a sensing component that can slide relative to the adsorption platform 3. The sensing component includes a detector 21 and a driving component 22 for controlling the lifting and lowering of the detector 21. The detector 21 is provided with a contact plate 211 and a detection head 212. The contact plate 211 is connected to the detector 21 through an elastic component 213 and is used to abut against the surface of the membrane electrode. The contact plate 211 has a detection hole for the detection head 212 to reciprocate through. The marking device 11 and the detector 21 are both located above the adsorption platform 3.

[0026] The aforementioned laser marking machine, by incorporating an adsorption platform 3, allows the membrane electrode to flatten under uniform negative pressure, ensuring a smooth processing surface and preventing laser defocusing or inconsistent marking depth due to unevenness. This also facilitates subsequent thickness measurement. A marking device 11 marks QR codes and other markings on the membrane electrode surface without physical contact, avoiding damage to fragile materials. A detector 21 measures the membrane electrode thickness in real-time during the marking process, detecting areas that are too thin or too thick. A contact plate 211, due to the flexible nature of the membrane electrode, prevents slight warping caused by internal stress or environmental temperature and humidity in its free state. The contact plate 211 mechanically abuts the membrane electrode surface, forcing it to a flat state, providing a stable reference plane for the subsequent detection head 212 and eliminating thickness measurement errors caused by material deformation.

The detection head 212 is fixedly inserted into the lifting base 25. When performing a test, the elastic element 213 can absorb the instantaneous impact force when the contact plate 211 is pressed down, preventing rigid collision damage to the surface of the membrane electrode. After the pressure is released, the elastic element 213 can also automatically push the contact plate 211 back to its initial position through the stored elastic potential energy, ensuring that the platform reset is consistent before each measurement / coding, and avoiding manual intervention.

[0040] Furthermore, the drive unit 22 is mounted on the lifting slide rail and is used to control the lifting state of the lifting seat 25.
