A laser marking device for FPC

Abstract

In the field of coding equipment technology, this invention specifically relates to a laser coding device for FPCs, including a laser coding equipment housing and a fixed worktable inside the housing. The fixed worktable has two positioning constraint blocks, each with a limiting constraint groove, a rotation constraint groove, and a reset constraint groove on its inner side. Each limiting constraint groove is connected to a corresponding rotation constraint groove, and each rotation constraint groove is connected to a corresponding reset constraint groove. A telescopic cylinder is activated to rotate a fixed gear, moving a lifting worktable carrying an FPC board directly below the coding constraint groove. The other lifting worktable is rotated 90° by the rotation of a rotation constraint column, stopping near another pile of FPC boards. This process of robotic arm operation is repeated, allowing for the replacement of FPC boards simply by the lifting cylinder moving the lifting worktable after processing. This reduces equipment waiting time and improves overall production efficiency.

Description

Technical Field

[0001] This invention relates to the field of marking equipment technology, and specifically to a laser marking device for FPC. Background Technology

[0002] Laser marking is a crucial step in the production of FPC (Flexible Printed Circuit) boards, used to mark relevant product information. The core component of the equipment, the laser generator, releases a high-intensity laser beam, which is precisely focused by an optical focusing system. This concentrates the laser energy onto the surface of the target object. Upon absorbing the laser energy, the material instantly undergoes physical or chemical changes such as ablation, vaporization, or discoloration, thereby accurately forming the desired text, numbers, graphics, QR codes, or other markings. Because laser marking is a non-contact process, it requires no molds or cutting tools and does not cause additional pressure or wear on the product.

[0003] The existing equipment uses a robotic arm to place the FPC board under the laser emitter on the worktable. After the marking is completed, the robotic arm removes it for replacement. At the same time, before laser marking, a positioning device is needed to constrain the FPC board to prevent the FPC board from shifting during the marking process, which could cause processing problems.

[0004] However, when the robotic arm moves the FPC board, it needs to move the FPC board twice in succession. During this time, the worktable has a lot of idle time that cannot be used for processing, resulting in a lot of waiting time and seriously affecting work efficiency. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a laser marking device for FPC, which can effectively solve the problem of inconvenience in the use of the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a laser marking device for FPC, including a laser marking device housing and a fixed worktable inside the laser marking device housing.

Each linkage constraint block is provided with a limiting constraint block on one side, and each limiting constraint block is provided with a fixing constraint plate on one side.

[0010] The reset assembly includes a connecting limiting post, a guide sleeve, and a transmission spur gear plate disposed inside the positioning constraint block. A fixed connecting block is provided on one side of the connecting limiting post, and one side of the fixed connecting block is connected to the guide constraint post. A reset spring is provided on one side of each fixed connecting block.

[0011] The transport component includes a rotating connecting block disposed between a fixed worktable and a support constraint plate, and two fixed constraint blocks connected to the rotating connecting block, each fixed constraint block having an abutment support plate on one side.

[0012] Furthermore, each of the limiting constraint grooves is provided with a transmission spur gear plate inside, each of the rotation constraint grooves is provided with a rotation gear inside, and each of the reset constraint grooves is provided with a reset spur gear plate inside, with each transmission spur gear plate meshing with the corresponding rotation gear.

[0013] Furthermore, each of the reset constraint slots meshes with a corresponding rotating gear, each reset spur plate has a linkage constraint block on one side, each positioning constraint block has a reset slot on one side, and each linkage constraint block has a connecting limit post on one side.

[0014] Furthermore, each of the connecting limiting posts is provided with a fixed connecting block on one side, each reset groove is provided with a guide sleeve on the inner side, each fixed connecting block is provided with a guide constraint post on one side, and each guide constraint post is sleeved on the inner side of the corresponding guide sleeve.

[0015] Furthermore, each of the fixed connecting blocks is sleeved on the corresponding guide sleeve, an FPC plate is provided between the two positioning connecting blocks, a marking constraint groove is opened on the fixed worktable, a lifting worktable is provided inside the marking constraint groove, and one side of the lifting worktable is in contact with the FPC plate.

[0016] Furthermore, a limiting lifting plate is provided on one side of the lifting worktable, one end of which abuts against two fixed constraint plates. A limiting fixing groove is opened on one side of the limiting lifting plate, and an abutting constraint groove is opened on another side of the limiting lifting plate. An abutting support plate is provided on one side of part of the limiting lifting plate, and a rotating connecting block is provided between the fixed worktable and the support constraint plate.

[0017] Furthermore, each of the abutting support plates is provided with an insertion positioning block on one side, and each insertion positioning block is inserted into the inner side of the corresponding limiting and fixing groove. A rotation constraint column is provided on one side of the rotating connecting block, and one end of the rotation constraint column passes through the support constraint plate and is suspended in the air.

[0018] Furthermore, a fixed connector is provided on one side of the support constraint plate, which is movably sleeved on the rotation constraint column. A right-angle rotating component is provided inside the fixed connector, which is sleeved and fixed on the rotation constraint column.

[0021] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0022] 1. Activate the telescopic cylinder to rotate the fixed gear, moving the lifting worktable with the FPC board directly below the marking constraint groove. The other lifting worktable rotates 90° by rotating the constraint column, stopping the lifting worktable near another pile of FPC boards. Repeat the above robotic arm operation, so that after the FPC board is processed, the lifting cylinder only needs to drive the lifting worktable to lift and lower to complete the replacement of the FPC board, reducing the waiting time of the equipment and improving the overall production efficiency.

[0023] 2. The lifting fixed column on one side of the lifting cylinder moves upward from below the support plate until it is inserted into the inner side of the constraint groove. The limiting lifting plate on one side of the lifting worktable abuts against the two fixed constraint plates, driving the meshing rotating gears to rotate together, so that the two positioning connecting blocks move closer to the coding constraint groove until the FPC board is limited on both sides, preventing the FPC board from moving during coding and improving the stability of coding.

[0052] The fixed gear 32 is sleeved and fixed on the rotating constraint column 31. A movable toothed plate 36 is provided on one side of the support constraint plate 3. The movable toothed plate 36 meshes with the fixed gear 32. A telescopic cylinder 35 is provided on one side of the movable toothed plate 36. A lifting cylinder 27 is provided on one side of the support constraint plate 3. A lifting fixed column 26 is provided on one side of the lifting cylinder 27. One end of the lifting fixed column 26 passes through the support constraint plate 3 and is inserted into the corresponding abutment constraint groove 25. Two positioning constraint members 38 are provided on the support constraint plate 3. Multiple FPC plates 21 are provided on one side of each positioning constraint member 38.

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

[0054] Working principle of the invention:

[0055] The first step involves a laser marking equipment housing 1 equipped with multiple openable doors. Multiple FPC boards 21 to be processed are placed through the doors on one side of the support constraint plate 3 and in contact with the positioning constraint member 38 to position them. The fixed worktable 2 is equipped with two robotic arms, one end of which is located between the fixed worktable 2 and the support constraint plate 3. The robotic arms use negative pressure to adsorb the FPC boards 21 and then move them to the top of the lifting worktable.

[0056] The second step involves activating the telescopic cylinder 35 to rotate the fixed gear 32, which in turn rotates the rotation constraint column 31. Simultaneously, the rotation connecting block 28 connected to the rotation constraint column 31 also rotates, moving the lifting worktable 22 with the FPC board 21 directly below the coding constraint groove 20. At the same time, another lifting worktable 22 is rotated 90° by the rotation of the rotation constraint column 31, causing the lifting worktable 22 to stop near another pile of FPC boards 21. The operation of the robotic arm described above is repeated.

[0057] Third, when the rotating constraint column 31 rotates, it drives the right-angle rotating component 34 to rotate inside the fixed connector 33 until the limiting connecting block 39 on one side of the right-angle rotating component 34 abuts against the fixed connector 33, thereby ending the rotation. At the same time, because the telescopic cylinder 35 changes its working direction in the next operation, its rotation changes to a 90° reverse rotation until the limiting connecting block 39 on one side of the right-angle rotating component 34 abuts against the fixed connector 33.

[0058] Fourth step: After the lifting worktable 22 is rotated, the lifting fixed column 26 on one side of the lifting cylinder 27 moves upward from the bottom of the support plate 30 until the lifting fixed column 26 is inserted into the inner side of the constraint groove 25. Then, the lifting worktable 22 is moved towards the fixed worktable 2. During this period, the limiting lifting plate 23 on one side of the lifting worktable 22 abuts against the two fixed constraint plates 14, causing the two fixed constraint plates 14 to move towards the fixed worktable 2, thereby causing the connected reset straight gear plate 11 to move, and driving the meshing rotating gear 7 to rotate together.

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

[0060] Step 6: After the lifting worktable 22 is reset, the rotating connecting block 28 is rotated so that another lifting worktable 22 and the FPC board 21 placed on it are moved to the bottom of the marking constraint groove 20. The operation is repeated. The processed FPC board 21 is taken out from one side of the laser marking equipment housing 1. The operation of the robotic arm is repeated until the marking 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, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions 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.
