Description

Technical Field

[0001] The utility model relates to the technical field of intelligent manufacturing, specifically to the technical field of an LED lamp board cutting device. Background Art

[0002] The demand for LED lamp boards in various application scenarios is increasing day by day. In order to pursue lighting effects and board manufacturing efficiency, through-hole LED lamp beads are directly soldered on the PCB. For this kind of LED lamp board, due to the protrusion of the LED lamp beads on the PCB board, existing automated cutting devices cannot be used universally. Therefore, manual segmentation is generally adopted, which makes it difficult to ensure the smoothness and consistency of the segmentation edge, thus affecting the quality and aesthetics of the product.

[0003] In this regard, for example, Chinese Patent CN118081875A, a cutting device for PCB circuit board production, discloses a solution in which, driven by the telescopic shaft of a hydraulic cylinder, a cross bar moves horizontally, and the movement of the cross bar drives the movement of a placement plate, so that the PCB circuit board on the placement plate can be conveniently adjusted in the cutting position.

[0004] However, when this solution is used for through-hole LED lamp beads, it is necessary to avoid the through-hole components and align the position by moving the cross bar, resulting in low efficiency. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model proposes an improved LED lamp board cutting device, aiming to improve the segmentation accuracy and the protection level of LED components, and ensure that the segmented LED lamp board has excellent quality and reliable performance.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] An LED lamp board cutting device includes a base, guide columns, a lower template, an upper template, a power plate sequentially sleeved on the guide columns, a lower die and an upper die arranged between the lower template and the upper template, a driving rod arranged between the upper template and the power plate, and a driving device arranged at the upper end of the power plate;

[0008] The upper die includes guide rods arranged at four corners, a hollow part in the middle, and a plurality of punches on the outer periphery of the hollow part;

[0009] The lower die includes positioning pins arranged at four corners of the lower die and through-type concave dies corresponding to the punches;

[0010] It further includes a hollow-shaped backing plate arranged between the lower template and the lower die.

[0011] Compared with the prior art, in this case, the PCB board with through-hole LED lamp beads is fixed by the positioning pins on the outer periphery of the lower die, and the through-hole die of the lower die is used to directly drop the stamping waste into the hollow part of the backing plate for recycling, while the hollow part on the upper die avoids the through-hole LED lamp beads to prevent damage.

[0012] In a preferred embodiment, the hollow part is two square parts arranged in a staggered manner. By arranging the two relatively small square parts in a staggered manner, while meeting the clearance requirements for the LED lamp beads, the stability of the upper die can be maintained as much as possible.

[0013] In some embodiments, it further includes a protective net arranged at the upper end of the hollow part.

[0014] In some embodiments, there are 2 positioning pins respectively at each corner, and they present a right angle at the guide rod.

[0015] In some embodiments, the punch includes an inner punch and an outer punch.

[0016] In some embodiments, the lower die includes a lower die core and a hollow lower die base.

[0017] In some embodiments, it further includes a control board arranged on the base, and the control board is provided with a start button and an emergency brake.

[0023] The following further details the features of the present invention and other related features through embodiments for the understanding of those skilled in the same industry:

[0024] It should be noted that the terms "upper" and "lower" used in the following description refer to the positional relationship of the upper and lower parts in the spatial scope. The terms "inner" and "outer" are also used to refer to the directions towards or away from the geometric center of a specific component respectively.

[0025] Please refer to Figure 1, an LED light board cutting device in this case includes a base 1, guide posts 2, a lower template 3, an upper template 4, and a power board 5 that are sequentially arranged sleeved on the guide posts 2. The base 1 is an operating platform, and 4 guide posts 2 are respectively provided at the four corners of the base 1. A lower die 6 and an upper die 7 are provided between the lower template 3 and the upper template 4.

[0026] It also includes a driving rod 51 provided between the upper template 4 and the power board 5, and a driving device 52 provided at the upper end of the power board 5. This is a relatively common setting in the field of stamping equipment, and no detailed description will be given to it.

[0027] In this case, it is the cutting of a PCB board that already has a V-shaped groove or a concave groove. Therefore, according to requirements, its drive can be selected from pneumatic, electric, or hydraulic, and all can be implemented. This case does not make specific restrictions on this. When the driving device 52 drives the driving rod 51 to move the upper template 4 up and down on the guide posts 2.

[0028] The following focuses on the application of the mold on this equipment. Further, please refer to Figures 2 to 4 , the upper die 7 includes an upper die core 71 and an upper die seat 72. Guide rods 73 are provided at the four corners of the upper die core 71. Actually, the guide rods 73 are provided on the upper die seat 72. Spring columns 74 are provided between the upper die core 71 and the upper die seat 72, which is a commonly used buffering means during stamping, and no detailed description will be given to it.

[0029] In the middle of the upper die core 71 of this case, there is a hollow part 75, and a plurality of punch heads 76 are provided on the outer periphery of the hollow part 75. In a preferred embodiment, the hollow part 75 is two square parts arranged in a staggered manner. By arranging two relatively small square parts in a staggered manner, while meeting the clearance for the LED lamp beads, the stability of the upper die core 71 can be maintained as much as possible. Further, in some embodiments, a protective net 77 is provided at the upper end of the hollow part 75. The function of the protective net 77 is to prevent damage caused by the LED lamp beads flying during stamping.

[0030] Further, a PCB board with a V-shaped groove or a concave groove generally includes a working board with LED lamp beads and a positioning board on the outer periphery. When cutting the board, in addition to separating the grooves between the working boards, the positioning board also needs to be separated. Therefore, the punch head 76 in this case includes an inner punch head 761 that is arranged around the hollow part 75 and cuts the grooves between the working boards, and an outer punch head 762 that separates the relationship between the working board and the positioning board.

[0031] As described above, the PCB board is provided with a positioning plate, and for this reason, a positioning device is provided on the lower template 6. Specifically, the lower template 6 includes a lower die core 61 and a lower die base 62, and positioning pins 63 are respectively provided at the four corners of the lower die core 61. Correspondingly, there will also be corresponding clearance on the upper die core 71 for the positioning pins 63, which will not be described in detail here. Preferably, two positioning pins 63 are provided at each corner respectively, specifically presenting a right angle at the guide rod 73. In this way, there is no need to set a special positioning function on the PCB board. As long as the size of the positioning plate conforms to the size of the mold, it can be completely positioned through the four corners, improving the versatility.

[0032] Furthermore, corresponding to the punch 76 of the upper die 7, a through-type female die 64 is provided on the lower die core 61. During stamping, the stamping waste will be discharged from the female die 64. Therefore, the corresponding lower die base 62 is provided in a hollow shape, so that the stamping waste can be directly discharged. In some embodiments, a hollow spacer 8 is provided between the lower die 6 and the lower template 3, so that the stamping waste directly falls into the hollow part of the spacer 8 for recycling.

[0033] Compared with manual plate cutting, using stamping plate cutting has potential safety hazards. For this reason, a control board 9 is provided on the base 1. The control board is provided with a start button 91 and an emergency brake 92. The start button 91 can be two buttons on both sides of the emergency brake 92. Safety sensors 93 are provided on both sides of the base 1, specifically between the control board 9 and the lower template 3, that is, used to determine whether the hand has left the die working area.

[0034] As described above, the present case protects an LED lamp board cutting device, and all technical solutions identical or similar to the present case should be regarded as falling within the protection scope of the present case.
