Description

Technical Field

[0001] The invention relates to the technical field of coding equipment, and in particular to a laser coding equipment for FPC. Background Art

[0002] In the production process of FPC (flexible circuit board), laser coding is an important process for marking relevant information of products. The core component of the equipment, the laser generator, releases a high-intensity laser beam, which is precisely focused by the optical focusing system, so that the laser energy is highly concentrated on the surface of the target object. After the object material absorbs the laser energy, it instantly produces physical or chemical changes such as ablation, vaporization, and discoloration, thereby accurately forming the required text, numbers, graphics, QR codes and other logos to achieve the purpose of marking. Because laser coding is a non-contact processing, it does not require molds or tools, and will not cause additional extrusion or wear on the product.

[0003] The existing equipment uses a robotic arm to place the FPC board under the laser launch platform of the workbench. After the coding is completed, the robotic arm will remove it for replacement. At the same time, before laser coding, a positioning device is required to constrain the FPC board to a certain extent to prevent the position of the FPC board from shifting during the coding process, which will cause processing problems.

[0004] However, when the robot arm moves the FPC board, it needs to move the FPC board twice in succession. During this period, the workbench has a lot of idle time that cannot be used for processing, resulting in a lot of waiting time, which seriously affects work efficiency. Summary of the invention

A lifting fixed column 26 is provided on one side of the lifting cylinder 27, and one end of the lifting fixed column 26 passes through the support constraint plate 3 and is inserted into the inner side of the corresponding abutment constraint groove 25. Two positioning constraints 38 are provided on the support constraint plate 3, and a plurality of FPC boards 21 are provided on one side of each positioning constraint 38.

[0053] The remaining structure is the same as that of Example 3.

[0054] Working principle of the present invention:

[0055] In the first step, a plurality of movable doors that can be opened are provided on the shell 1 of the laser coding equipment. A plurality of FPC boards 21 to be processed are placed on one side of the support and constraint plate 3 through the movable doors and contact the positioning and constraint parts 38, so as to position them. Two mechanical arms are provided on the fixed workbench 2, and one end of the mechanical arm is arranged between the fixed workbench 2 and the support and constraint plate 3. The FPC board 21 is adsorbed by negative pressure and then moved above the lifting workbench.

[0056] In the second step, the telescopic cylinder 35 is started to rotate the fixed gear 32, so that the rotation constraint column 31 rotates together, and the rotation connection block 28 connected to the rotation constraint column 31 also rotates, and the lifting workbench 22 with the FPC board 21 is moved to the bottom of the coding constraint groove 20. At the same time, the other lifting workbench 22 is rotated 90° by the rotation of the rotation constraint column 31, so that the lifting workbench 22 stops near another pile of FPC boards 21, and the operation of the above-mentioned robot arm is repeated.

[0057] The third step is that when the rotation constraint column 31 rotates, the right-angle rotating member 34 is driven to rotate inside the fixed connecting member 33 until the limit connecting block 39 on one side of the right-angle rotating member 34 abuts against the fixed connecting member 33, thereby ending the rotation. At the same time, because the telescopic cylinder 35 changes its working direction for the next time, its rotation is changed to a reverse rotation of 90° until the limit connecting block 39 on one side of the right-angle rotating member 34 abuts against the fixed connecting member 33.

[0058] In the fourth step, after completing the rotation of the lifting workbench 22, the lifting fixed column 26 on one side of the lifting cylinder 27 moves upward from the bottom of the abutment support plate 30 until the lifting fixed column 26 is inserted into the inner side of the abutment constraint groove 25, and then drives the lifting workbench 22 to move toward the side of the fixed workbench 2. During this period, the limiting lifting plate 23 on one side of the lifting workbench 22 abuts against the two fixed constraint plates 14, driving the two fixed constraint plates 14 to move toward the side of the fixed workbench 2, thereby moving the connected reset spur plate 11, driving the meshing rotating gear 7 to rotate together.

[0059] The fifth step, when the rotating gear 7 rotates, it drives the meshing transmission spur plate 8 to move, so that the two positioning connecting blocks 9 are close to the coding constraint groove 20, until the lifting cylinder 27 drives the lifting workbench 22 to stop moving, the two positioning connecting blocks 9 are also set on both sides of the FPC board 21 for limiting, and then the laser coding device on the coding support 40 is used for coding. After the coding operation is completed, the lifting cylinder 27 drives the lifting workbench 22 to move downward, and the reset spring 16 also drives the linkage constraint block 12 to move to reset it.

[0060] Step 6. After the lifting workbench 22 is reset, the rotating connecting block 28 is rotated to move another lifting workbench 22 and the FPC board 21 placed thereon to below the coding constraint groove 20. The operation is repeated. The processed FPC board 21 is taken out from one side of the laser coding equipment housing 1, and the operation of the robotic arm is repeated until the coding of this batch of FPC boards 21 is completed.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
