Abstract
Description
Technical Field
[0001] This utility model relates to the field of diode manufacturing equipment, and in particular to a diode dispensing fixture and a diode dispensing jig. Background Technology
[0002] Diode dispensing is a crucial encapsulation step in the manufacturing process of LEDs. The core of an LED is its chip and internal circuitry. The adhesive formed after dispensing can isolate external impurities, separate different electrodes, prevent leakage or short circuits, ensure normal circuit operation, and protect the stability and lifespan of the core components. At the same time, dispensing can produce refraction and scattering effects through the properties of the adhesive, adjusting the LED's emission angle, color temperature, or brightness, thereby improving its optical performance and making the light emission effect more in line with application requirements.
[0003] Currently, diode dispensing is mostly carried out in a continuous automated production line mode, such as the diode dispensing machine disclosed in patent document CN214637856U, which uses a conveyor belt and a tray fixture to dispense and encapsulate diodes on the tray through a dispensing device.
[0004] However, in the existing production methods, diodes have different sizes, such as 3mm and 5mm. The tray fixtures need to use dispensing positioning holes that match the type of LED for dispensing operations. They also need to match the shape of the LED. Since LEDs have various shapes and sizes, different types of matching dispensing tray fixtures are required for different types, resulting in a large number of fixtures on the production line, complicated equipment storage and management, and high production costs. Summary of the Invention
[0005] This invention addresses the problems of high production costs and complex equipment redundancy management in current diode dispensing and encapsulation processes, which require corresponding tray fixtures for diodes of different sizes. It provides a more versatile diode dispensing tooling and a diode dispensing fixture.
[0006] To address the aforementioned problems, firstly, the technical solution adopted by this utility model is a diode dispensing fixture, comprising a guide seat, which includes two opposing baffles. A guiding mechanism is provided between the baffles, and the guiding direction of the guiding mechanism is perpendicular to the baffles. Two clamping blocks are slidably mounted on the guiding mechanism. A first positioning groove is formed on the upper surface of each clamping block on one side close to the other. The two first positioning grooves interlock to form a receiving space for clamping the diode. A spring is also provided between the baffles and the clamping blocks. The clamping blocks are automatically clamped by the spring, which can accommodate diodes of different sizes, solving the problem that traditional special fixtures can only correspond to a single model, and improving clamping stability and ease of operation.
[0007] As a preferred embodiment of a diode dispensing fixture, the cross-section of the first positioning groove is an isosceles trapezoid, with the long base of the trapezoid located on the side where the two clamping blocks are close to each other. The trapezoidal structure is adaptable to diodes of various shapes, such as round and square, expanding the fixture's applicability while reducing the difficulty of diode alignment and improving operational efficiency.
[0008] As a preferred implementation of a diode dispensing fixture, the bottom surface of the first positioning groove has a wire hole. This accommodates diodes with leads, protects the leads from damage, and ensures that the adhesive covers the connection area between the leads and the chip during dispensing, thus improving dispensing quality.
[0009] As a preferred embodiment of a diode dispensing fixture, the guiding mechanism includes at least two guide rods, each end of which is fixedly connected to two baffles. The clamping block is slidably threaded onto the guide rods. The guide rods ensure smooth sliding of the clamping block, preventing uneven force on the diode during clamping and thus preventing skewing. They also simplify the assembly process of the fixture and reduce maintenance costs.
[0010] As a preferred embodiment of a diode dispensing fixture, the spring is sleeved on the guide rod and located between the baffle and the clamping block. Furthermore, the second positioning groove has the same structure as the first positioning groove, maintaining compatibility with various diodes and further reducing changeover costs.
[0011] As a preferred implementation of a diode dispensing fixture, a second positioning groove is provided on the opposite side of the upper surface of the two clamping blocks, and the structure of the second positioning groove is the same as that of the first positioning groove.
[0012] Secondly, this utility model also provides a diode dispensing fixture, including a fixture tray on which multiple diode dispensing toolings as described above are arranged. This solution achieves batch operation through the integration of multiple toolings, significantly improving dispensing efficiency; the standardized design of the fixture tray is compatible with mainstream dispensing equipment, reducing equipment adaptation costs.
[0013] As a preferred embodiment of a diode dispensing fixture, the fixture tray is rectangular, and multiple partitions are evenly spaced and parallel to each other on the upper surface of the fixture tray. The diode dispensing fixture is disposed between adjacent partitions, and two baffles of the diode dispensing fixture are fixedly connected to the partitions on its two sides, respectively. The partitions form an installation space for multiple dispensing fixtures, increasing the density of diode clamping.
[0014] As can be seen from the above technical solutions, the advantages of this utility model are as follows: The tooling of this solution uses a spring-driven clamping block for automatic clamping, which can be adapted to diodes of different sizes, solving the problem that traditional special fixtures only correspond to a single model, and improving clamping stability and ease of operation; the isosceles trapezoidal first positioning groove can adapt to diodes of various shapes such as round and square, reducing the difficulty of placement and alignment and improving operational efficiency; the wire hole on the bottom of the groove is adapted to diodes with leads, which can protect the leads from damage and ensure dispensing quality; the guide rod ensures that the clamping block slides smoothly, prevents the diode from tilting, and simplifies the assembly process and reduces maintenance costs; the spring sleeved on the guide rod is not easily twisted or deformed, extending its service life and improving the stability of the tooling; the second positioning groove on the clamping block has the same structure as the first positioning groove, maintaining compatibility with various diodes and further reducing the cost of changing models. The diode dispensing fixture achieves batch operation through the integration of multiple tooling, which greatly improves dispensing efficiency; the standardized design of the fixture tray is compatible with mainstream dispensing equipment, reducing equipment adaptation costs; the partitions on the rectangular tray form multiple tooling installation spaces, increasing the diode clamping density.

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0021] Example 1
[0022] like Figure 1 As shown, this embodiment provides a diode dispensing fixture, including a guide seat 1. The guide seat includes two baffles 1-1 arranged opposite each other along a first straight line direction. The two baffles 1-1 are parallel to each other, and the surface of the baffles 1-1 is perpendicular to the first straight line direction. A guiding mechanism is provided between the baffles 1-1, and the guiding direction of the guiding mechanism is arranged along the first straight line direction, that is, perpendicular to the baffles 1-1. Two clamping blocks 2 are slidably mounted on the guiding mechanism. In this embodiment, the guiding mechanism includes at least two (two in this embodiment) guide rods 1-2. The two ends of the guide rod 1-2 are fixedly connected to the two baffles 1-1 respectively. The two clamping blocks 2 are slidably connected to the guide rod 1-2. The clamping blocks slide along a fixed direction through the guide rod to ensure that the movement trajectories of the two clamping blocks are parallel and to avoid deviation during clamping. A spring 3 is also provided between the baffle 1-1 and the clamping block 2. The spring 3 is sleeved on the guide rod 1-2 and located between the baffle 1-1 and the clamping block 2. One end of the spring abuts against the baffle 1-1 and the other end abuts against the clamping block 2, and pushes the two clamping blocks 2 toward each other.
[0023] The upper surface of the clamping blocks 2 has a first positioning groove 2-1 on one side close to each other. The two first positioning grooves 2-1 are joined together to form a receiving space for clamping the diode. In this embodiment, the cross-section of the first positioning groove 2-1 is an isosceles trapezoid. The long base of the isosceles trapezoid is located on the side close to each other of the two clamping blocks 2. The isosceles trapezoid is preferably set with a base angle of 60° and the length of the short base is equal to the length of the leg. Thus, the two first positioning grooves 2-1 are joined together to form a regular hexagon, which has a better centering effect. The bottom surface of the first positioning groove 2-1 is also provided with a wire hole 2-3. When clamping a through-hole diode, its pin can pass through the wire hole to avoid the pin being deformed by pressure or affecting the clamping stability. When dispensing glue, the glue can penetrate along the gap between the pins to ensure the integrity of the glue dispensing.
[0024] Furthermore, a second positioning groove 2-2 is provided on the opposite side of the upper surface of the two clamping blocks 2, and the structure of the second positioning groove 2-2 is the same as that of the first positioning groove 2-1.
[0025] In this embodiment, when the tooling is in use, the light-emitting diode is placed at the joint of the first positioning groove of the two clamping blocks. The elastic force of the spring will push the clamping blocks to move towards the middle along the guide mechanism. The inclined side of the trapezoid guides the diode, and the diode contacts the waist (hyposide) of the trapezoid. The diode is clamped by the receiving space formed by the two first positioning grooves. After the glue is applied, the clamping blocks are pulled to both sides to compress the spring, and the diode can be removed.
[0026] Example 2
[0027] This embodiment further provides a diode dispensing fixture, including a fixture tray 4, on which multiple diode dispensing fixtures provided in Embodiment 1 are arranged, such as... Figure 2 As shown, the fixture tray 4 is rectangular, and multiple partitions 5 are equally spaced on the upper surface of the fixture tray 4. The multiple partitions 5 are parallel to each other. The diode dispensing fixture is arranged between adjacent partitions 5, and the two baffles 1-1 of the diode dispensing fixture are fixedly connected to the partitions 5 on its two sides respectively.
[0028] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: the tooling of this solution uses a spring-driven clamping block for automatic clamping, which can be adapted to diodes of different sizes, solving the problem that traditional special fixtures only correspond to a single model, and improving clamping stability and ease of operation; the isosceles trapezoidal first positioning groove can adapt to diodes of various shapes such as round and square, reducing the difficulty of placement and alignment and improving operational efficiency; the wire hole on the bottom of the groove is adapted to diodes with leads, which can protect the leads from damage and ensure dispensing quality; the guide rod ensures that the clamping block slides smoothly, prevents the diode from tilting, and simplifies the assembly process and reduces maintenance costs; the spring sleeved on the guide rod is not easily twisted or deformed, extending its service life and improving the stability of the tooling; the second positioning groove on the clamping block has the same structure as the first positioning groove, maintaining compatibility with various diodes and further reducing the cost of changing models. The diode dispensing fixture achieves batch operation through the integration of multiple tooling, which greatly improves dispensing efficiency; the standardized design of the fixture tray is compatible with mainstream dispensing equipment, reducing equipment adaptation costs; the partitions on the rectangular tray form multiple tooling installation spaces, increasing the diode clamping density.
