Description

Technical Field

[0001] This utility model relates to the field of electronic component manufacturing technology, and in particular to a fixture and laser marking device. Background Technology

[0002] Laser marking machines use laser technology to create permanent marks on the surfaces of various materials. Due to their advantages such as high precision, low damage, and rapid response, they are widely used in industry, medicine, daily life, and technology. Especially on semiconductor electronic components, laser marking has become an important method for printing identification codes.

[0003] In the production of radio frequency (RF) electronic components, manual laser marking machines are commonly used equipment. However, due to the wide variety of RF components and their significant differences in package shape and size, ranging from a few millimeters to tens of millimeters, precise positioning becomes extremely challenging. During production, operators need to constantly perform manual adjustments and repositioning to accommodate components of different sizes and shapes. This frequent adjustment not only consumes a lot of time, reducing marking efficiency, but also easily causes positioning errors, further affecting the consistency of marking positions and product quality. Utility Model Content

[0004] To address the aforementioned problems, this application provides a fixture and a laser marking device.

[0005] In a first aspect, this application provides a clamp, which adopts the following technical solution:

[0006] A fixture includes a carrier plate having a positioning unit, the positioning unit having a positioning groove for placing a product to be marked, the center of the positioning groove coinciding with the projection of the center of the positioning unit onto a first plane.

[0007] Preferably, the carrier plate has a plurality of the positioning units;

[0008] And / or, at least the portion of the carrier plate that contacts the marked product is made of insulating material;

[0009] And / or, the cross-sectional area of ​​the positioning groove gradually decreases from the opening side to the bottom side.

[0010] Preferably, the positioning groove extends through the carrier plate.

[0011] Preferably, the carrier plate is provided with a boss to prevent the product to be marked from falling out from the other side of the positioning groove.

[0012] Preferably, the carrier plate includes a first surface and a second surface that are parallel to each other, the first surface being parallel to the first plane, and the positioning groove being formed along a direction perpendicular to the first surface and / or the second surface.

[0013] Preferably, the carrier plate includes at least two unit plates, each unit plate having at least one positioning unit, and adjacent unit plates are detachably connected.

[0014] Preferably, the positioning slots on adjacent unit plates have the same or different dimensions.

[0015] Preferably, the unit board is provided with a connecting groove, and adjacent unit boards are connected through the connecting groove;

[0016] And / or, the unit plate is provided with a connecting protrusion, and adjacent unit plates are connected through the connecting protrusion.

[0017] Preferably, the positioning groove is a stepped groove along the thickness direction of the carrier plate.

[0018] Secondly, this application provides a laser marking device, which adopts the following technical solution:

[0019] A laser marking device includes a worktable and a marking mechanism. The worktable is provided with a fixture as described in the above technical solution. The worktable is parallel to the first plane. The marking mechanism is positioned according to the center point of the positioning unit.

[0020] This utility model has the following advantages and beneficial effects:

[0021] This invention enables laser marking machines to complete marking operations efficiently and stably by precisely positioning the product to be marked using a carrier plate. Specifically, before marking, the laser marking machine and the carrier plate are positioned using coordinates. During the positioning process, the center point of the positioning unit is aligned with the laser marking machine. This means that when the product to be marked is placed in the positioning slot, its center will coincide with the center of the positioning unit in the marking direction of the laser marking machine.

[0022] Because laser marking machines use the center point of the positioning unit for coordinate positioning, even if the product to be marked is changed to a different size or model, the center of the product to be marked will still remain in the center position of the positioning unit. In this way, the laser marking machine can accurately locate the coordinates using the center point of the positioning unit, thereby achieving efficient and precise marking of products of different sizes.

[0023] The biggest advantage of this solution is that it eliminates the need for repositioning each time, regardless of changes in the size or model of the product to be marked. This avoids errors caused by multiple positioning attempts, significantly shortens marking time, and improves marking efficiency. Furthermore, by reducing the number of positioning operations, it ensures consistency in the marking position, effectively improving product quality. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0035] The following is in conjunction with the appendix Figures 1 to 6 The present application provides a detailed description of a fixture and laser marking device through specific embodiments and application scenarios.

[0036] The first aspect of this embodiment describes a fixture in detail.

[0037] This application provides a fixture for use in a marking device. For example, the marking device is a laser marking device. After the product to be marked is positioned using the fixture, marking can be performed. It should be noted that the fixture can be integrally mounted on the marking device or designed to be detachable, facilitating flexible application in different scenarios.

[0038] In some schemes, refer to Figure 1 , Figure 2 The fixture includes a carrier plate 100, which has a positioning unit 110. The positioning unit 110 has a positioning groove 111 for placing the product to be marked. The center of the positioning groove 111 coincides with the projection of the center of the positioning unit 110 onto a first plane. Here, the first plane is a plane perpendicular to the laser marking direction, that is, the marking direction of the laser marking device is perpendicular to the first plane.

[0039] For example, the carrier board 100 may be made of a PCB board or other suitable material. The positioning units 110 can be formed by marking lines on the carrier board 100, such as a grid area formed on the carrier board 100. Each positioning unit 110 has a positioning groove 111 formed along the thickness direction of the carrier board 100. It is understood that the size of the positioning groove 111 is less than or equal to the size of the positioning unit 110; that is, the positioning groove 111 is always located within the area of ​​the positioning unit 110.

[0040] During operation, the product to be marked is placed in the corresponding positioning slot 111. The shape and size of the positioning slot 111 ensure accurate positioning of the product. Specifically, the center of the positioning slot 111 aligns with the center of the product to be marked through the slot's connection, ensuring that the center of the product coincides with the center of the positioning slot 111, and that both are aligned along the same straight line in the marking direction of the laser marking machine. This structural design simplifies the marking process to some extent, especially for products of different models and sizes. It avoids the need for complex repositioning steps each time a product is changed, thus saving time and improving marking efficiency.

[0041] Since the positioning groove 111 is opened along the thickness direction of the carrier plate 100, this design not only helps to stably position products of different thicknesses, but also improves the positioning accuracy and avoids errors caused by unstable product placement. The design of the positioning groove 111 ensures that even if the product to be marked is changed, the product's positioning position remains consistent, improving the accuracy and consistency of the marking process.

[0042] According to an optional embodiment, refer to Figure 1 , Figure 2 The carrier plate 100 has multiple positioning units 110. By aligning the center coordinates of the positioning units 110 with multiple positions of the marking device, multiple products can be marked at once. Specifically, when multiple products are placed in the positioning slots 111 simultaneously, by aligning the center coordinates of each positioning unit 110, the laser marking device can mark multiple products in the same operation, significantly improving work efficiency and making it particularly suitable for mass production.

[0043] According to an optional embodiment, at least the portion of the carrier board 100 in contact with the marked product is made of insulating material. This is particularly important when marking electronic components, which typically have leads. Short circuits in these leads can damage the electronic components. By employing an insulating material design, current that may be generated during the marking process can be effectively isolated, preventing malfunctions caused by short circuits in the leads. This design is significant in protecting electronic components, especially in high-precision electronic product marking, as it improves product reliability and reduces the risk of damage.

[0044] According to an optional embodiment, refer to Figure 1 , Figure 3The cross-sectional area of ​​the positioning groove 111 gradually decreases from the opening side to the bottom side. This design is suitable for products with the same shape but different sizes, allowing products of different sizes to be effectively placed and positioned in the positioning groove 111. Specifically, the cross-sectional area of ​​the positioning groove 111 refers to the cross-sectional area along the direction perpendicular to the depth of the positioning groove 111. As the depth of the positioning groove 111 increases, the groove opening gradually narrows, thereby better accommodating products of different sizes, ensuring that the product is stably placed in the positioning groove 111, and avoiding positioning inaccuracies caused by differences in product size.

[0045] According to an optional embodiment, refer to Figure 1 , Figure 2 The positioning groove 111 extends through the carrier plate 100. Specifically, the positioning groove 111 extends from one opening on one side of the carrier plate 100 to the other, forming a channel that runs through the entire carrier plate 100. This design allows the product to be marked to be more stably fixed when placed in the positioning groove 111, avoiding insecure positioning caused by excessive product thickness or inaccurate positioning. At the same time, this structural design further enhances the adaptability of the fixture, especially in applications requiring larger products or omnidirectional support.

[0046] According to an optional embodiment, refer to Figure 1 , Figure 5 The carrier plate 100 is provided with a boss 111a to prevent the product to be marked from falling out of the other side of the positioning groove 111. Specifically, a boss 111a is provided on the bottom side or the other end side of the positioning groove 111 to prevent the product to be marked from sliding out of the positioning groove 111 due to external force during placement. This design ensures that the product to be marked maintains a stable position during the marking process, avoids displacement of the product during marking, and ensures the accuracy and consistency of marking. It can be understood that by providing the boss 111a, the opening on the other side of the positioning groove 111 can be made smaller than the size of the product to be marked, thereby preventing the product to be marked from falling out of the other side of the positioning groove 111.

[0047] According to an optional embodiment, the carrier plate 100 includes a first surface 120 and a second surface 130 that are parallel to each other. The first surface 120 is parallel to a first plane, and the positioning groove 111 is formed in a direction perpendicular to the first surface 120 and / or the second surface 130. In use, the second surface 130 is positioned and installed with the marking device, and the first surface 120 faces the marking side. This design allows the product to be marked in the positioning groove 111 to be positioned in a direction perpendicular to the first surface 120, thereby ensuring that the marking direction is aligned with the positioning groove 111 during the marking process, and the product can be accurately marked.

[0048] According to an optional embodiment, refer to Figure 1 , Figure 2 The carrier plate 100 includes at least two unit plates 140, each unit plate 140 having at least one positioning unit 110, and adjacent unit plates 140 are detachably connected. This design allows the number of unit plates 140 to be adjusted according to the size and batch quantity of the products to be marked in actual production, thereby controlling the number of products marked at one time. By flexibly adjusting the number of unit plates 140, the production cycle can be effectively managed, improving the adaptability and production efficiency of the production line.

[0049] According to an optional embodiment, the positioning slots 111 on adjacent unit plates 140 have the same or different dimensions. In actual production, there may be small batches of sample products, or products of different sizes that need to be marked simultaneously. To save production time and avoid frequent fixture changes, unit plates 140 with positioning slots 111 of different sizes can be combined together to mark products of different sizes in the same batch simultaneously without repositioning, thereby further improving production efficiency.

[0050] According to an optional embodiment, refer to Figure 1 , Figure 2 Each unit panel 140 is provided with a connecting groove 141, through which adjacent unit panels 140 are connected. In use, a rod structure can be inserted into the connecting groove 141 to achieve a stable connection between two unit panels 140. This design facilitates convenient disassembly and assembly, especially when adjusting the number of unit panels 140 or replacing unit panels 140, making operation more flexible.

[0051] According to an optional embodiment, unit plate 140 is provided with connecting protrusions 142, and adjacent unit plates 140 are connected via connecting protrusions 142. The connecting protrusions 142 cooperate with connecting grooves 141, allowing the connecting protrusions 142 to be inserted into the connecting grooves 141 when docking is required, thereby completing the connection between unit plates 140. This design makes the connection between unit plates 140 more stable, ensures positioning accuracy during production, and simplifies the disassembly and assembly process.

[0052] According to an optional embodiment, refer to Figure 1 , Figure 4 The positioning groove 111 is a stepped groove along the thickness direction of the carrier plate 100. The stepped groove design can accommodate products of different sizes to be marked. For example, the opening size of the stepped groove gradually decreases along the thickness direction of the carrier plate 100, thereby securely fixing products of different sizes. This design not only improves positioning accuracy but also effectively prevents offset problems caused by different product sizes during the marking process, ensuring consistency and stability during marking.

[0053] The second aspect of this embodiment describes in detail a laser marking apparatus.

[0054] Reference Figure 1 , Figure 6 A laser marking device includes a worktable 10 and a marking mechanism 11. The worktable 10 is equipped with a fixture as described in the above embodiment. The worktable 10 is parallel to a first plane. The marking mechanism 11 is positioned according to the center point of a positioning unit 110. During use, the second surface 130 of the fixture is placed against the surface of the worktable 10. At this time, the first surface 120 of the fixture is perpendicular to the marking direction, thereby achieving accurate positioning and marking of the product to be marked.

[0055] Specifically, the fixture design on the worktable 10 ensures accurate docking between the fixture and the marking device during use. Using the center point of the positioning unit 110 as a marking reference, the marking machine can perform high-precision marking based on this center point. The first surface 120 of the fixture is set perpendicular to the marking direction, ensuring that the center position of the product to be marked is always aligned with the marking direction of the marking machine, thereby improving the accuracy and consistency of marking.

[0056] To further improve the stability and positioning accuracy of the fixture during the marking process, refer to Figure 6 Furthermore, a limiting structure can be installed on the worktable 10 for precise positioning of the carrier plate 100. This limiting structure physically guides the carrier plate 100 on the worktable 10, preventing the fixture from shifting or displacing during operation and ensuring that each marking operation is performed in the same position. This design is particularly important in high-speed or mass production, significantly improving production efficiency and marking consistency.

[0057] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
