Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser marking machine technology, specifically to a laser marking machine for electronic components. Background Technology
[0002] Laser marking machines for electronic components use high-energy-density laser beams to irradiate the surface of materials, achieving permanent marking through "thermal processing" or "cold processing" effects. Marking machines are categorized into thermal and cold processing. Thermal processing involves laser energy melting and evaporating the material surface to form a clear mark (suitable for metals, ceramics, etc.). Cold processing, on the other hand, uses ultraviolet lasers (355nm wavelength) to break chemical bonds, achieving heat-free marking and preventing deformation of heat-sensitive components (such as flexible PCBs and polymer materials), making it particularly suitable for high-density integrated circuits and micro-sensors. However, traditional laser marking machines are not convenient for restricting the position of electronic components, requiring adjustments to the laser component's position based on the placement. This can lead to inaccurate laser marking and affect the overall usability.
[0003] To overcome the aforementioned defects, existing technology (Chinese Patent No. CN220196620U, Publication Date: 2023-12-19) provides a laser marking machine for electronic components, comprising a marking machine body and a placement table. The placement table is located on top of the marking machine body and is fixedly connected to the marking machine body by welding. Positioning posts are provided on both sides of the top of the placement table. The marking machine body has a positioning hole on the side near the positioning posts that cooperates with the positioning posts. A movable groove is provided at the bottom of the positioning posts. By using a fixing mechanism, a fixing groove, a control groove, and a fixing clamp in conjunction, pressing the push plate causes the push plate to drive the fixing block through a sliding rod to compress the first spring and enter the inner cavity of the movable groove. This solves the problem that existing laser marking machines, when marking electronic components, are prone to displacement due to external force, causing the electronic components to become misaligned, resulting in a change in the marking position and potential damage to small parts on the electronic components.
[0004] The aforementioned mechanism uses a fixing mechanism to press and restrict the position of electronic components. However, in actual use, it cannot restrict the same position of each identical electronic component. This results in deviations in the marked position of each electronic component during the manufacturing process, affecting the accuracy of the electronic components during production. Utility Model Content
[0005] The purpose of this invention is to provide a laser marking machine for electronic components, in order to solve the problem mentioned in the background art that the same position of each identical electronic component cannot be restricted, which leads to deviations in the marking position of each electronic component during the electronic component processing, affecting the accuracy of electronic component production.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic component laser marking machine, comprising a worktable, an installation box installed at the middle position of the top of the worktable, and a laser marking component slidably connected to the side of the installation box, a drive motor installed at the top of the installation box, and a threaded rod installed at the output end of the drive motor, a movable block threadedly connected to the outer side of the threaded rod, and one side of the movable block extending to the outside of the installation box and connected to the laser marking component, a placement plate provided on the top side of the worktable below the laser marking component; a positioning hole is provided on the surface of the placement plate, and a limiting mechanism for assisting in the positioning and placement of electronic components is provided inside the positioning hole, the limiting mechanism including a limiting frame, the limiting frame being disposed on the surface of the placement plate, and a limiting block matching the positioning hole being provided at the bottom end of the limiting frame; an adjusting rod is provided on the side of the top of the worktable near the placement plate, and a positioning mechanism for secondary restriction of the electronic components is provided inside the adjusting rod.
[0007] Furthermore, a second elastic airbag is attached to the bottom of the positioning hole, and a pressing plate is attached to the top of the second elastic airbag. A first elastic airbag is attached to the upper inner side of the positioning hole above the second elastic airbag, and the first elastic airbag and the second elastic airbag are connected by a flexible tube.
[0008] Furthermore, the bottom of the upper outer side of the limiting block is in contact with the top of the first elastic airbag, and the lower outer side of the limiting block is in contact with the inner side of the second elastic airbag.
[0009] Furthermore, the inner side of the pressing plate is fitted to the outer side of the limiting block, and the pressing plate and the positioning hole are vertically slidably connected.
[0010] Furthermore, the positioning mechanism includes a driven gear, which is slidably connected to the inside of the adjusting rod. A pressing rod is engaged with the top of the driven gear, and a rubber block is installed at the bottom of the pressing rod. The bottom of the rubber block is in contact with the top of the placement plate.
[0011] Furthermore, the adjusting rod is internally rotatably connected to a drive gear, and the drive gear meshes with the driven gear.
[0012] Furthermore, a return spring is wound around the upper end of the outer side of the pressing rod, and the pressing rod and the driven gear form an elastic structure through the return spring.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By utilizing the "L" shape of the limiting frame itself, the sides of electronic components can be fitted or positioned with the corners inside the limiting frame, so that electronic components of the same batch maintain basically the same position during processing, thus ensuring that the marking position is the same when laser marking is performed on the surface of electronic components using the laser marking assembly.
[0015] Furthermore, by rotating the output end of the drive motor and driving the threaded rod to rotate, the threaded rod and the movable block are connected by a thread, so that when the movable block is driven, it can synchronously drive the laser marking component to move up and down to achieve marking processing, and the marking height can be flexibly adjusted according to the needs.
[0016] Furthermore, by utilizing the engagement between the limiting block at the bottom of the limiting frame and the positioning hole, the limiting block can compress the first elastic airbag. The gas inside the first elastic airbag is thus compressed and transported through the hose to the inside of the second elastic airbag. As the gas inside the second elastic airbag increases, the inner side of the second elastic airbag and the lower outer side of the limiting block are kept in full contact, thereby stabilizing the position of the limiting block. The pressing plate can further restrict the position of the limiting block, effectively preventing the limiting block from wobbling when engaging with the positioning hole, which could lead to unstable placement of electronic components.
[0017] 2. Positioning holes are evenly spaced on the surface of the placement plate. Each positioning hole is equipped with a limit mechanism. The multiple positioning holes allow the limit frame to adjust its position according to the specific situation of the electronic components, so that the limit frame can adapt to electronic components of different sizes and increase the overall flexibility during use.
[0018] Furthermore, by using the elastic force of the return spring, the bottom of the rubber block can contact the surface of the electronic component, thereby using the rubber block to restrict the position of the electronic component, effectively preventing the electronic component from shifting during the marking process, and increasing the overall stability during use.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The technical solution shown addresses the problem that the inability to restrict the same position for every identical electronic component leads to deviations in the marking position of each electronic component during processing, affecting the accuracy of electronic component production. This electronic component laser marking machine discloses a limiting mechanism, including a worktable 1. A mounting box 2 is installed at the center of the top of the worktable 1, and a laser marking component 6 is slidably connected to the side of the mounting box 2. A drive motor 3 is installed at the top of the mounting box 2, and a threaded rod 4 is installed at the output end of the drive motor 3. A movable block 5 is threadedly connected to the outer side of the threaded rod 4, and one side of the movable block 5 extends to the outside of the mounting box 2 and connects to the laser marking component 6. A placement plate 7 is provided on the top side of the worktable 1 below the laser marking component 6; the surface of the placement plate 7 has positioning holes 9. The internal part of the 9 is provided with a limiting mechanism for assisting in the positioning and placement of electronic components. The limiting mechanism includes a limiting frame 10, which is disposed on the surface of the placement plate 7. The bottom end of the limiting frame 10 is provided with a limiting block 11 that matches the positioning hole 9. The bottom end of the positioning hole 9 is attached to a second elastic airbag 14, and the top end of the second elastic airbag 14 is attached to a pressing plate 13. The upper inner side of the positioning hole 9 above the second elastic airbag 14 is attached to a first elastic airbag 12, and the first elastic airbag 12 and the second elastic airbag 14 are connected by a flexible tube. The bottom of the upper outer side of the limiting block 11 is attached to the top end of the first elastic airbag 12, and the lower outer side of the limiting block 11 is attached to the inner side of the second elastic airbag 14. The inner side of the pressing plate 13 is attached to the outer side of the limiting block 11, and the pressing plate 13 and the positioning hole 9 are vertically slidably connected.
[0028] In this example, such as Figure 1 and Figure 3 As shown, the electronic components to be processed are placed on the surface of the placement plate 7. The limiting frame 10 engages with the positioning hole 9 through the limiting mechanism, thus keeping the position of the limiting frame 10 unchanged. Utilizing the "L" shape of the limiting frame 10 itself, the sides of the electronic components can be fitted or positioned against the inner corner of the limiting frame 10. This ensures that electronic components of the same batch maintain essentially the same position during processing, resulting in identical marking positions when laser marking is applied to the surface of the electronic components using the laser marking assembly 6. Figure 2 As shown, the output end of the drive motor 3 rotates, driving the threaded rod 4 to rotate. The threaded rod 4 and the movable block 5 are connected by a thread, so that when the movable block 5 is driven, it can synchronously drive the laser marking component 6 to move up and down to achieve marking processing. The marking height can be flexibly adjusted according to the needs. Figure 5As shown, a first elastic airbag 12 is provided at the upper end of the limiting mechanism. The limiting block 11 at the bottom of the limiting frame 10 engages with the positioning hole 9, allowing the limiting block 11 to compress the first elastic airbag 12. The gas inside the first elastic airbag 12 is thus compressed and transported through a hose to the inside of the second elastic airbag 14. As the gas inside the second elastic airbag 14 increases, the inner side of the second elastic airbag 14 and the lower outer side of the limiting block 11 maintain a fully fitted state, thereby stabilizing the position of the limiting block 11. Furthermore, the pressing plate 13 provides a secondary restriction on the position of the limiting block 11, effectively preventing positional wobbling when the limiting block 11 engages with the positioning hole 9, which could lead to instability in the placement of electronic components. Figure 3 As shown, the surface of the placement plate 7 is provided with positioning holes 9 at equal intervals. Each positioning hole 9 is provided with a limiting mechanism. By using multiple positioning holes 9, the limiting frame 10 can fully adjust its position according to the specific situation of the electronic components, so that the limiting frame 10 can adapt to electronic components of different sizes and increase the overall flexibility during use.
[0029] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The technical solution shown addresses the problem that when marking electronic components, the side of the electronic component may be in contact with the inner side of the limiting frame 10, and the position may shift due to device shaking. The electronic component laser marking machine discloses a positioning mechanism. An adjusting rod 15 is provided on the top of the worktable 1 near the placement plate 7, and the adjusting rod 15 has a positioning mechanism for secondary restriction of the electronic component. The positioning mechanism includes a driven gear 17, which is slidably connected to the inside of the adjusting rod 15. A pressing rod 18 is engaged at the top of the driven gear 17, and a rubber block 19 is installed at the bottom of the pressing rod 18. The bottom of the rubber block 19 is in contact with the top of the placement plate 7.
[0030] In this example, such as Figure 6As shown, by moving the pressing rod 18 upward, the rubber block 19 is separated from the placement plate 7. After the electronic component is attached to the inner side of the limiting frame 10, the tension applied to the pressing rod 18 is removed, allowing the pressing rod 18 to reset by the elastic force of the return spring 8. This allows the bottom end of the rubber block 19 to contact the surface of the electronic component, thereby using the rubber block 19 to restrict the position of the electronic component, effectively preventing the electronic component from shifting position during marking and increasing the overall stability during use. The elastic force of the return spring 8 can quickly pull the pressing rod 18 upward, and when the pressing rod 18 loses tension, it will also reset synchronously by the elastic force, increasing the overall flexibility during use.
[0031] Example 3: Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The technical solution shown addresses the problem that the bottom of the rubber block 19 cannot make contact with the electronic components due to their different sizes: the laser marking machine for electronic components discloses an adjustment mechanism, in which the internal rotating connection of the adjustment rod 15 is a drive gear 16, and the drive gear 16 meshes with the driven gear 17; a return spring 8 is wound around the upper end of the outer side of the pressing rod 18, and the pressing rod 18 and the driven gear 17 form an elastic structure through the return spring 8.
[0032] In this example, such as Figure 6 As shown, the drive gear 16 rotates, meshing with the driven gear 17, causing the driven gear 17 to move outwards towards the adjusting rod 15. This, in turn, causes the pressing rod 18 to move synchronously towards the position of the placement plate 7. The meshing of the drive gear 16 and the driven gear 17 ensures that the bottom of the rubber block 19 remains in contact with the electronic components. Simultaneously, the driven gear 17 and the adjusting rod 15 are laterally slidingly connected, allowing the driven gear 17 to move more smoothly due to its meshing with the drive gear 16.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
