Abstract
Description
Technical Field
[0001] This utility model relates to the field of marking machine technology, and in particular to a marking device. Background Technology
[0002] In the electronics manufacturing industry, chip marking is a crucial process. It plays a vital role in assigning unique identification information to chips, which is indispensable for chip traceability, identification, and subsequent production management and quality control. As the core equipment for chip marking, the performance of the marking machine directly affects the quality and efficiency of the marking process.
[0003] In actual production, chips are typically encapsulated in tape and reel for convenient transportation and automated production operations. Tape and reel are generally made of flexible plastic or paper materials. While this softness facilitates chip storage and transmission to some extent, it also presents several problems during the marking process. When a marking machine marks the chips on the tape and reel, the chips move along with the tape. However, due to the tape's soft texture, it is easily deformed by its own weight, slight external pressure, or inertia during movement. This deformation prevents the chips on the tape from remaining stably on the same plane, resulting in chips at different positions exhibiting unevenness.
[0004] Traditional laser marking machines typically use fixed-width guide rails or conveyor belts. This structure, designed from the outset, has a fixed transport channel width, making it impossible to directly adjust for products of varying widths during production. To address the marking needs of products with different widths, some traditional laser marking machines have adopted replaceable guide rails or conveyor belt components for width adjustment. However, this adjustment method presents several inconveniences in practice. First, it requires stopping the machine to disassemble and replace components, which not only interrupts the production process and reduces efficiency but also increases downtime and production costs. Second, replacing components requires specialized technicians with high skill levels; improper operation can lead to component damage or inaccurate installation, affecting the machine's normal operation and marking quality.
[0005] Therefore, this application develops a marking device to solve the problems existing in the prior art. Utility Model Content
[0006] The purpose of this invention is to provide a marking device to solve the problem of deviations that easily occur when marking machines perform marking in the prior art.
[0007] The technical solution of this utility model is: a marking device, comprising:
[0008] A feeding device is used to provide the chip tapes to be marked;
[0009] The unloading device is used to receive the marked chip tapes;
[0010] The marking mechanism, located between the feeding device and the unloading device, includes: a workbench, a conveying track, and a clamping mechanism;
[0011] The conveying track is fixedly installed on the workbench and extends along the direction of chip tape movement. Its two ends are respectively connected to the discharge port of the loading device and the inlet of the unloading device. The clamping mechanism is fixed on the workbench and provides clamping power through the first driving device to apply clamping force to the chip tape placed on the conveying track.
[0012] The marking machine is located above the conveying track, with its marking head facing the chip tape surface and moving along the chip tape movement direction via a fourth driving device.
[0013] Preferably, the clamping mechanism includes a fixing part and a clamping part disposed opposite to each other, wherein the fixing part remains relatively stationary with respect to the conveying track, and the clamping part is controlled by the first driving device, which drives the clamping part to generate displacement, so that the fixing part and the clamping part move closer to each other to fix the chip tape.
[0014] Preferably, the clamping part has a groove on the side near the conveying track, and the two sides of the groove form contact parts along the length direction. When the clamping part approaches the contact parts under the drive of the driving device, the two contact parts contact the chip tape and make the chip tape contact the contact parts.
[0015] Preferably, the conveying track includes two guide rails arranged in a parallel state, and a second driving device is provided at each end of the two guide rails. The two guide rails move closer to each other or further away from each other through the driving action of the second driving device.
[0016] Preferably, the second driving device has a screw with opposite threads, and fixing blocks are respectively installed at the positions of the opposite threads of the screw. The two fixing blocks are respectively installed on the two guide rails, driving the guide rails to move in a direction perpendicular to the chip tape movement direction.
[0017] Preferably, the workbench is provided with a support member located below the conveying track. The support member is provided with a sliding device adjacent to the guide rail. The sliding device includes a slide rail and a pair of slide tables. The slide rail is fixed on the support member, and the pair of slide tables are slidably disposed on the slide rail and respectively fixedly connected to the corresponding guide rail.
[0018] Preferably, the workbench is provided with a limiting plate and is arranged along the chip tape-and-reel movement direction. A pair of limiting blocks are symmetrically arranged on the limiting plate, and the two limiting blocks are respectively located on both sides of the conveying track along the chip tape-and-reel movement direction, for limiting the movement of the guide rail.
[0019] Preferably, the marking machine is mounted on the fourth drive device via an electric cylinder, driving the marking machine to move along a direction perpendicular to the chip tape feeding direction.
[0020] Preferably, the marking mechanism further includes an isolation device located on one side of the conveying track along the chip tape movement direction. The isolation device includes a third driving device and an isolation cover. The third driving device causes the isolation cover to move closer to or away from the conveying track along a direction perpendicular to the chip tape movement direction.
[0021] Preferably, the isolation device is connected to an air suction device, which creates a negative pressure inside the isolation device when the isolation cover is placed on the conveying track.
[0022] Compared with the prior art, the advantages of this utility model are:
[0023] (1) The conveying track consists of two symmetrical guide rails. With the help of the screw structure of the second drive device, the two fixed blocks installed on the screw drive the guide rails to move closer or further away from each other along the direction perpendicular to the chip tape movement, thereby flexibly adjusting the distance between the two guide rails. This can meet the conveying needs of products of different widths and enhance the versatility and applicability of the equipment.
[0024] (2) A sliding device is installed at the adjacent position of the support component and the guide rail on the workbench. The guide rail is fixed on the support component. The slide table is connected to the guide rail and can slide on the guide rail. When the guide rail moves, the slide table slides in a straight line under the support and guidance of the guide rail, ensuring that the guide rail moves according to the predetermined trajectory and speed, realizing the precise adjustment of the product in the carrying space, and ensuring the stability and accuracy of the conveying process.
[0025] (3) The groove opened on the side of the clamping part near the conveying track, during the clamping process, the contact parts on both sides of the groove contact the chip tape and apply an upward force, so that the chip tape and the fixing part are in close contact. The groove reduces the damage to the chip tape surface caused by large-area extrusion, while providing a space for the chip tape to be accommodated, avoiding excessive extrusion deformation, and protecting the integrity and performance of the chip.
[0026] (4) The marking machine is connected to the fourth drive device through an electric cylinder. Under the drive of the fourth drive device, it can move along the direction of chip tape movement to achieve the marking action. At the same time, the electric cylinder can also make the marking machine move in a straight line perpendicular to the direction of chip tape movement. It can be adjusted according to the chip tape laying situation to avoid poor marking effect due to small deviations, thus improving the marking accuracy and flexibility. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to specific embodiments:
[0036] like Figures 1-3As shown, a marking device includes a feeding device 1, a discharging device 2, a marking mechanism 3, and a marking machine 5. The feeding device 1 provides chip tapes to be marked for subsequent marking processes, ensuring the continuity and stability of the marking process. The discharging device 2 is located at the end of the marking process and receives the chip tapes that have already been marked. The marking mechanism 3 is located between the feeding device 1 and the discharging device 2, and includes a worktable 31, a conveyor rail 32, and a clamping mechanism 33. The worktable 31 serves as the supporting foundation for the marking mechanism 3, providing a stable mounting platform for the conveyor rail 32 and the clamping mechanism 33, ensuring the stability and reliability of the entire marking mechanism 3 during operation. The conveyor rail 32 is fixedly installed on the worktable 31 and extends along the movement direction of the chip tapes. Its two ends are precisely connected to the outlet of the feeding device 1 and the inlet of the discharging device 2, respectively, forming a continuous conveying channel through which the chip tapes can be transported. Guided by the conveyor track 32, the chip tape smoothly moves from the loading device 1 to the unloading device 2, realizing an automated conveying process. The clamping mechanism 33 is fixed on the worktable 31 and is provided with clamping power by the first drive device 4. After the chip tape is placed on the conveyor track 32, the clamping mechanism 33 can apply a suitable clamping force to the chip tape to fix it stably on the conveyor track 32, preventing the chip tape from moving or shaking during the marking process, thereby ensuring the accuracy of the marking position and the marking quality. The marking machine 5 is set above the conveyor track 32, with its marking head facing the surface of the chip tape. The fourth drive device 51 makes the marking machine 5 move along the movement direction of the chip tape, and performs precise marking operations on the surface of the chip tape while moving, realizing the printing of various marks, patterns or text.
[0037] In this embodiment, the conveying track 32 consists of two symmetrically arranged guide rails 321, which move closer or further apart via a second driving device 322. The second driving device 322 has a screw (not shown in the figure) with opposite thread directions at both ends (one end is a left-hand thread, and the other end is a right-hand thread). Fixing blocks 323 are installed on the screw at positions corresponding to the opposite threads. Specifically, one fixing block 323 is installed on the left-hand thread section, and another fixing block 323 is installed on the right-hand thread section. The two fixing blocks 323 are respectively mounted on the corresponding guide rails 321. When the second driving device 322 is activated, the screw begins to rotate. Because the threads at both ends of the screw are opposite in direction, during the rotation of the screw, the fixing blocks 323 installed on the left-hand thread section and the fixing blocks 323 installed on the right-hand thread section will move in opposite directions as the threads rotate. Since the fixing block 323 is connected to the guide rail 321, the two guide rails 321 can move closer to each other or further away from each other along the direction perpendicular to the chip tape movement, thereby adjusting the distance between the two guide rails 321 to accommodate different product widths.
[0038] Specifically, such as Figure 5 As shown, a support member 6 is provided on the workbench 31. A sliding device 61 is provided adjacent to the support member 6 and the guide rail 321. The sliding device 61 includes a slide rail 611 and a pair of slide tables 612. The slide rail 611 is fixedly mounted on the support member 6, and its length direction is parallel to the chip tape-and-reel movement direction. The pair of slide tables 612 are slidably mounted on the slide rail 611 and are respectively fixedly connected to the corresponding guide rail 321. In actual operation, when the second drive device 322 drives the guide rail 321 to move, the guide rail 321 will transmit the force to the connected slide table 612. Under the support and guidance of the slide rail 611, the slide table 612 slides linearly along the length direction of the slide rail 611, ensuring that the guide rail 321 moves according to the predetermined trajectory and speed, thereby achieving precise adjustment of the product in the carrying space.
[0039] Furthermore, such as Figures 4-5 As shown, a limiting structure is provided on the worktable 31 and installed on it. This structure mainly consists of a limiting plate 7 and a limiting block 71, which restricts the movement of the guide rail 321. The limiting plate 7 is elongated and set along the chip tape movement direction. Its length is reasonably designed according to the expected movement range of the guide rail 321. It not only provides a mounting base for the limiting block 71, but also provides support for the guide rail 321. A pair of limiting blocks 71 are symmetrically arranged on the limiting plate 7. When the second driving device 322 drives the guide rail 321 to move along the direction perpendicular to the chip tape movement direction, the guide rail 321 will move linearly under the guidance of the sliding device 61. As the guide rail 321 moves, when it approaches the set limit position, the side of the guide rail 321 will contact the corresponding limiting block 71, thereby limiting the movement range of the guide rail 321. This effectively prevents the equipment from being damaged due to excessive movement of the guide rail 321 and ensures the safe operation of the equipment.
[0040] In this embodiment, as Figure 6 As shown, the clamping mechanism 33 includes a fixed part 331 and a clamping part 332 arranged opposite to each other. The fixed part 331 is fixedly mounted on the limiting block 71 and remains relatively stationary with respect to the conveying track 32. The clamping part 332 is connected to the first driving device 4, and its movement is controlled by the first driving device 4. When the first driving device 4 receives a corresponding driving command, it drives the clamping part 332 to move towards the fixed part 331. As the clamping part 332 moves closer to the fixed part 331, the distance between the two gradually decreases. When the two reach a suitable distance, a bidirectional constraint force is applied to the chip tape placed on the conveying track 32 between the fixed part 331 and the clamping part 332. Through this bidirectional compression, the chip tape is firmly fixed on the conveying track 32, ensuring that the chip tape will not shift or shake during the subsequent marking process.
[0041] Specifically, such as Figure 6 As shown, a groove 333 is provided on the side of the clamping part 332 near the conveying track 32, and the groove 333 extends along the length direction of the clamping part 332, with contact parts 334 naturally formed on both sides. In actual operation, when the first driving device 4 drives the clamping part 332 to move towards the fixing part 331, as the clamping part 332 continues to rise, the contact parts 334 on both sides of the groove 333 will gradually approach the chip tape placed on the guide rail 321. Eventually, the two contact parts 334 will directly contact the chip tape, and under the continuous upward action, the contact parts 334 will apply an upward force to the chip tape, causing the chip tape to move upward until it is in close contact with the fixing part 331 located above and covering the guide rail 321, thus achieving stable fixing. Furthermore, the design of the groove 333 also protects the chip tape. During the process of the clamping part 332 rising and contacting the chip tape, the contact area between the fixing part 331 and the chip tape is relatively small and flat, reducing damage to the surface of the chip tape caused by large-area compression. At the same time, the groove 333 can provide a relatively accommodating space for the chip tape, preventing the chip tape from being excessively squeezed and deformed during the fixing process, protecting the integrity and performance of the chip on the chip tape, and reducing losses and costs in the production process.
[0042] In this embodiment, as Figure 3 As shown, the marking machine 5 is connected to the fourth drive device 51 via the electric cylinder 8. The electric cylinder 8 serves as an intermediate transmission component, with one end fixed to the fourth drive device 51 and the other end connected to the marking machine 5. Under the drive of the fourth drive device 51, the marking machine 5 can move along the chip tape movement direction to achieve the marking action. The electric cylinder 8 enables the marking machine 5 to move linearly along a direction perpendicular to the chip tape movement direction, thereby allowing adjustments to be made based on the chip tape laying condition and avoiding poor marking results due to minor deviations.
[0043] Furthermore, such as Figure 1As shown, the marking mechanism 3 is also equipped with an isolation device 9, which is located on one side of the conveying track 32 along the chip tape-making direction. The isolation device 9 includes a third driving device 91 and an isolation cover 92. The third driving device 91 can drive the isolation cover 92 to move it closer to the conveying track 32 to form an isolation space, or move it away from the conveying track 32 to release the isolation state, meeting the environmental isolation requirements of different working conditions during the marking process. Furthermore, the isolation device 9 is connected to a suction device (not shown in the figure). Specifically, when the isolation cover 92 is accurately placed on the conveying track 32 under the drive of the third driving device 91, the suction device immediately starts working. At this time, the suction device performs a suction operation on the internal space of the isolation device 9 through the pipeline, so that the gas pressure inside the isolation device 9 drops rapidly, thereby forming a stable micro-negative pressure environment inside the isolation device 9. This effectively removes pollutants such as dust and exhaust gas generated during the marking process in a timely manner, avoiding any impact on compliance.
