Description

Technical Field

[0001] This utility model relates to the field of LED bead cutting technology, and in particular to an LED bead cutting and collecting device. Background Technology

[0002] Traditional LED chip board cutting often employs a combined approach of static pressure fixing and roller cutting. The board is fixed by pressing down on the LED chips, and the cutting action is completed by rotating the roller. This method is widely used in mass production due to its simple structure, low cost, and convenient operation, and can quickly complete batch cutting.

[0003] However, continuous pressure from a stationary roller cutter can cause concentrated stress on the LED beads, leading to deformation or even breakage. This is especially true during high-speed cutting, where pressure fluctuations exacerbate the risk of damage, directly impacting product yield and increasing rework costs. Therefore, a cutting and collecting device for LED bead boards that avoids compressing the LED beads during cutting is needed. Utility Model Content

Detailed Implementation

[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Specific embodiments, combined with Figures 1 to 9 The technical solution of this utility model is further illustrated as shown.

[0022] After processing, the LED chips in the LED chip board need to be cut to separate individual chips for easy storage and application. Traditional processes rely on continuously pressing the LED chips to fix the cutting position of the rotary cutter. This operation easily causes local stress concentration in the LED chips, leading to deformation or breakage. Especially in high-speed cutting scenarios, pressure fluctuations further amplify the probability of damage, directly reducing product yield and increasing rework costs. To address this, this invention proposes a non-compression LED chip board cutting and collecting device, which optimizes the cutting mechanism design to complete the cutting of the LED chip board.

[0023] Overall, combined Figure 1 As shown, the LED bead board cutting and collecting device includes a feeding mechanism 1 for feeding LED bead boards, a collecting mechanism 2 for collecting the cut products on one side of the feeding mechanism 1, a cutting mechanism 3 for cutting LED bead boards and a driving mechanism (not shown in the figure) for driving the cutting mechanism 3 to move are provided between the feeding mechanism 1 and the collecting mechanism 2. The cutting mechanism 3 includes a first roller cutter 31 and a second roller cutter 32 that cooperates with the first roller cutter 31 to complete the cutting of LED beads on the LED board.

[0024] Based on the above overall design concept, the first roller cutter 31 and the second roller cutter 32 cooperate to form a shearing cutting structure. The cutting force is perpendicular to the plane of the lamp bead arrangement, avoiding the application of radial pressure to the lamp bead body and reducing the damage of mechanical stress to the internal structure of the lamp bead. The dual roller cutter collaborative cutting design effectively avoids the damage risk caused by directly pressing the lamp bead in the traditional lamp bead board cutting.

[0025] In the above-described cutting mechanism 3 configuration, preferably, the first roller cutter 31 includes a first blade body 311 and a plurality of first cutting blades 312 arranged in an equally spaced array along its axial direction, each of the first cutting blades 312 protruding from the outer peripheral wall of the first blade body 311; the second roller cutter 32 includes a second blade body 321 and a plurality of second cutting blades 322 arranged in an equally spaced array along its axial direction, each of the second cutting blades 322 protruding from the outer peripheral wall of the second blade body 321, the second cutting blades 322 being axially aligned with the first cutting blades 312, the first roller cutter 31 and the second roller cutter 32 being arranged parallel to each other axially and rotating in opposite directions on both axes to cut the connection between adjacent lamp beads on the lamp bead board.

[0026] Specifically, combined Figure 2 , Figure 3 As shown, the first cutting blade 312 and the second cutting blade 322 are axially aligned and distributed in an equally spaced array to form a cutting path that precisely matches the spacing between the LED beads. The cutting force is concentrated in the connection area between adjacent LED beads rather than the LED bead body, avoiding mechanical stress damage to the internal structure of the LED beads caused by radial pressure. In addition, the dual-axis counter-rotating motion causes the cutting blades to form a shearing action, improving the flatness of the cutting edge.

[0027] To further enhance the performance of the cutting mechanism 3, preferably, it is combined with Figures 5 to 9 As shown, the first cutting blade 312 has an integrally formed inclined first cutting edge surface 3121, and the first cutting edge surface 3121 is spaced apart from the surface of the first blade body 311; the second cutting blade 322 has a corresponding inclined second cutting edge surface 3221, and the second cutting edge surface 3221 is spaced apart from the surface of the second blade body 321. The second cutting edge surface 3221 and the first cutting edge surface 3121 form a complementary wedge structure on the axial projection plane to form a double-blade shearing system and cut off the connection between adjacent lamp beads on the lamp bead board.

[0028] Based on the above configuration, the complementary wedge structure formed by the first cutting edge 3121 and the second cutting edge 3221 in axial projection constitutes a double-blade shearing system. During cutting, the two cutting edges work together to generate shearing force, achieving precise matching between the cutting path and the spacing of the LED beads, and improving the flatness of the cutting edge. In addition, by setting an inclined and complementary wedge structure, the problem of the first roller cutter 31 and the second roller cutter 32 being too close together is avoided.

[0029] To further enhance the performance of the cutting mechanism 3, preferably, the first blade body 311 has first mounting ends 3111 on both sides, and the second blade body 321 has second mounting ends 3211 on both sides corresponding to the first mounting ends 3111. Each first mounting end 3111 and its adjacent first cutting edge 312 are spaced apart, and each second mounting end 3211 and its adjacent second cutting edge 322 are spaced apart. The driving mechanism is connected to the first mounting ends 3111 and the second mounting ends 3211 to drive the rotation of the first hobbing cutter 31 and the second hobbing cutter 32.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, the minimum edge distance between adjacent first cutting blades 312 is greater than the width of the LED bead, the spacing between adjacent first cutting blades 312 is less than the spacing between adjacent LED beads on the LED bead board, and the width of the first cutting blade 312 is less than the minimum edge distance between adjacent LED beads on the LED bead board.

[0031] As mentioned above, the spacing between adjacent first cutting blades 312 is smaller than the spacing between adjacent LEDs in the same row of the LED bead board, to ensure that the cutting path accurately covers the connection area between LEDs and avoids damage to the LED body caused by cutting blade deviation. The width of the first cutting blade 312 is smaller than the minimum edge distance between adjacent LEDs in the same row of the LED bead board, reducing the contact area with the LEDs during cutting, reducing the risk of mechanical stress concentration, forming a safe cutting gap, avoiding direct pressure of the cutting blade on the LED surface, effectively preventing hidden damage to the internal structure of the LED due to external impact, achieving precise control of the cutting force application area, improving cutting accuracy and edge quality, and reducing the LED breakage rate.

[0032] It should be noted that the second cutting blade 322 is axially aligned with the first cutting blade 312 and is distributed in an array with equal spacing. The spacing between adjacent second cutting blades 322 and the width of each second cutting blade 322 are set to correspond to the relevant settings of the first cutting blade 312.

[0033] It should be noted that, based on the above overall design concept, the technical solution of this application can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, combined with Figure 7 , Figure 8 As shown, a plurality of first cutting blades 312 are symmetrically distributed on both sides along the axial direction of the first blade body 311, and a plurality of second cutting blades 322 are symmetrically distributed on both sides along the axial direction of the second blade body 321.

[0034] The design of the cutting blades, symmetrically distributed on both sides, achieves mechanical balance and improves precision during the cutting process. Specifically, the symmetrical layout distributes the cutting force evenly on both sides of the blade axis, effectively suppressing blade offset or vibration caused by unilateral force, ensuring precise matching between the cutting path and the spacing between the LED beads, and reducing burrs or hidden damage to the LED bead edges caused by mechanical shaking. When working in conjunction with the symmetrical cutting blades of the second roller cutter 32, a balanced shearing force field is formed, avoiding uneven force on the LED bead body and reducing the risk of stress concentration in the internal structure.

[0035] To further expand the performance of the LED bead plate cutting and collecting device, preferably, it is combined with Figure 1 As shown, a conveyor belt 11 for conveying the LED bead board material into the cutting mechanism 3 is provided between the feeding mechanism 1 and the cutting mechanism 3.

[0036] To further enhance the performance of the LED bead board cutting and collecting device, preferably, multiple sets of double roller cutting units are arranged in an array at equal intervals along the conveying path of the conveyor belt 11 within the cutting mechanism 3. Each set of double roller cutting units includes a first roller 31 and a second roller 32 that rotate in opposite directions on two axes.

[0037] By arranging multiple sets of double roller cutting units in an array, continuous and efficient operation and improved precision of LED bead board cutting are achieved. In addition, the collaborative work of multiple units can disperse the cutting force, reduce the pressure of single-point cutting, form a continuous shearing force field on the conveying path, optimize the mechanical distribution of the cutting process, reduce the risk of damage to the LED bead body due to local stress concentration, and improve the flatness of the cutting edge.

[0038] In addition, to further expand the performance of the LED bead board cutting and collecting device, the collecting mechanism 2 includes a first collecting component 21 for collecting complete LED beads and a second collecting component 22 for collecting the cut LED bead board substrate. A first groove 211 for guiding LED beads to the first collecting component 21 is provided between the cutting mechanism 3 and the first collecting component 21. A second groove 221 for guiding LED bead board substrate to the second collecting component 22 is provided between the second collecting component 22 and the cutting mechanism 3. The first collecting component 21 is located on the bottom side of the second collecting component 22, and the first groove 211 is located on the bottom side of the cutting mechanism 3.

[0039] Specifically, the bottom of the first chute 211 is provided with a third receiving member 23 for collecting cutting residual waste. The first chute 211 is a vibrating screen that can vibrate to dislodge the cutting residual waste to the third receiving member 23 and transport the LED beads to the first receiving member 21.

[0040] Based on the above configuration, the third receiving component 23 is located on the bottom side of the cutting mechanism 3 and the first chute 211. The first chute 211 adopts a vibrating screen structure, which uses mechanical vibration to promote the shedding of cutting residue such as chips and glue residue and guides them into the third receiving component 23 through the screen holes, thus avoiding secondary pollution or mechanical scratches caused by waste adhering to the surface of the LED beads. In addition, the vibration effect simultaneously optimizes the LED bead conveying efficiency and reduces damage to the LED bead surface caused by friction.

[0041] More specifically, the third receiving component 23 is dedicated to waste collection and forms a physically isolated classification and storage system with the first receiving component 21 and the second receiving component 22, thereby improving the purity of each material being recycled. The overall design reduces the need for manual sorting through a dynamic separation mechanism, reduces the risk of contact damage during the transfer of LED beads, and maintains the cleanliness of the production environment.

[0042] The present invention proposes a lamp bead board cutting and collecting device, wherein multiple first cutting blades 312 are symmetrically distributed on both sides along the axial direction of the first blade body 311, and multiple second cutting blades 322 are symmetrically distributed on both sides along the axial direction of the second blade body 321. The first cutting blades 312 are provided with an inclined first cutting edge surface 3121, and the second cutting blades 322 are correspondingly provided with an inclined second cutting edge surface 3221. The second cutting edge surface 3221 is separated from the surface of the second blade body 321, and the second cutting edge surface 3221 and the first cutting edge surface 3121 form a complementary wedge structure in the axial projection plane.

[0043] When cutting the LED chip board, the first roller cutter 31 and the second roller cutter 32 rotate in opposite directions on two axes. The first cutting edge 312 and the second cutting edge 322 are axially aligned. The second cutting edge surface 3221 and the first cutting edge surface 3121 combine to form a shearing action, thereby improving the flatness of the cutting edge.

[0044] After the LED beads are cut, the cutting waste falls into the first chute 211 along with the LED beads. The first chute 211 is a vibrating screen, which uses mechanical vibration to promote the removal of the cutting waste and guide it through the screen holes to the third receiving component 23, thereby optimizing the LED bead conveying efficiency and conveying the LED beads to the first receiving component 21. The cut LED bead board substrate falls into the second receiving component 22 through the second chute 221.

Detailed explanations of configurations, examples of specific structural arrangements, and descriptions of assembly and connection methods are provided to ensure sufficient disclosure so that those skilled in the art can better implement this application, and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
