Description

Technical Field

[0001] The invention relates to the technical field of LED light source plate cutting, and in particular to a cutting device for producing LED products. Background Art

[0002] An LED lamp is an electroluminescent semiconductor material chip, which is cured onto a bracket with silver glue or white glue, and then connected to the chip and the circuit board with silver wire or gold wire. It is sealed with epoxy resin on all sides to protect the internal core wire, and finally the outer shell is installed. Therefore, the LED lamp has good shock resistance. In the production of LED lamps, an LED light source board cutting device is required; however, the workbench of the existing cutting device lacks a mechanism for fixing the LED light source board, which causes the LED light source board to shake easily during cutting, which in turn causes irregular notches or crooked cutting at the cutting position of the LED light source board.

[0003] Therefore, there is a cutting device for LED lamp head production with patent number CN220050241U to solve the above problems. However, the device has the following defects when in use, such as: since the spacing between the two sets of limit plates is fixed, it cannot be applied to products of different widths, and the position of the pressure plate is fixed. When it is applied to the processing of products of different widths, it may be located directly above the middle area of ​​the product, causing it to move down to fix the product, easily causing squeezing of components in the middle area of ​​the top of the product, thereby damaging the product. Summary of the invention

[0004] The purpose of the present invention is to provide a cutting device for producing LED products.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0006] A cutting device for producing LED products, comprising a machine platform, wherein an equipment box is fixed above the machine platform through a bracket, and a cutting knife group driven by a hydraulic rod is arranged in the equipment box:

[0007] On both sides of the top of the machine table, there are limiting mechanisms for clamping and fixing the LED light source board. The limiting mechanism includes a U-shaped plate with an opening facing the corresponding bracket direction. On the top of the machine table inside the opening of the U-shaped plate, there is a mounting plate. On the inner side wall of the opening of the U-shaped plate, there are a limiting rod and a screw rod passing through the mounting plate. On the mounting plate, there is a screw tube sleeved on the screw rod, and on the side wall of the U-shaped plate, there is a rolling bearing for fixing the screw rod. On the top of the U-shaped plate, there is also a fixing plate located above the mounting plate. On the fixing plate, there is an L-shaped frame, and on the L-shaped frame, there is an electric push rod. On the output shaft of the electric push rod, there is a pressing plate located outside the U-shaped plate. The pressing plate is located between two groups of U-shaped plates. On the bottom end surface of the pressing plate, there are grooves and multiple arc-shaped grooves. Inside the grooves, there are pressure sensors. The arc-shaped grooves are connected to a vacuum pump through hoses.

[0008] Preferably, through holes for the limiting rods to pass through are provided on the mounting plate.

[0009] Preferably, a driving block is provided at the end of the screw rod, and the screw rod is fixedly connected to the screw tube by screwing.

[0010] Preferably, the U-shaped plate is suspended above the machine table, and the distance between the bottom of the U-shaped plate and the top end of the machine table is 0.1 - 0.2 cm.

[0011] Preferably, multiple arc-shaped grooves are axially provided on the outer side wall of the U-shaped plate, and a rubber protective layer is also provided on the outer side wall of the U-shaped plate.

[0012] Preferably, the number of the limiting rods is not less than two groups. Multiple limiting rods are fixedly connected to the inner side wall of the vertical end of the U-shaped plate. At the bottom of one end of the limiting rod, there is also a roller group abutted against the top end surface of the machine table. The roller group is arranged at the bottom of the limiting rod close to the side wall of the vertical end of the U-shaped plate.

[0013] The beneficial effects of the present invention are as follows: By adjusting the distance between the U-shaped plates in the two limiting mechanisms, the processing requirements of LED light source boards with various different widths can be met. When the U-shaped plate moves, it will drive the pressing plate to displace through the fixing plate, the L-shaped frame, and the electric push rod, so that the pressing plate is always located at the edge of the area between the two groups of U-shaped plates. After clamping and fixing the LED light source board between the two groups of U-shaped plates, the electric push rod can drive the pressing plate to move downwards, so that the pressing plate is located at the blank areas on both sides of the top edge of the LED light source board.

Specific embodiments

[0018] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the drawings.

[0019] A cutting device for LED product production includes a machine table 1, wherein an equipment box 2 is fixed above the machine table 1 through a bracket 3, and a cutting knife group driven by a hydraulic rod is arranged in the equipment box 2:

[0020] Limiting mechanisms 4 for clamping and fixing the LED light source board are arranged on both sides of the top of the machine table 1. The limiting mechanism 4 includes a C-shaped plate 41 with an opening facing the corresponding bracket 3. An installation plate 42 is arranged on the top of the machine table 1 inside the opening of the C-shaped plate 41. A limiting rod 43 and a screw rod 44 passing through the installation plate 42 are arranged on the inner side wall of the opening of the C-shaped plate 41. A through hole for the limiting rod 43 to pass through is opened on the installation plate 42. A screw tube 45 sleeved on the screw rod 44 is further arranged on the installation plate 42, and a rolling bearing 46 for fixing the screw rod 44 is arranged on the side wall of the C-shaped plate 41;

[0021] A fixing plate 47 located above the installation plate 42 is also erected on the top of the C-shaped plate 41. An L-shaped frame 48 is arranged on the fixing plate 47, and an electric push rod 49 is arranged on the L-shaped frame 48. A pressing plate 410 located outside the C-shaped plate 41 is arranged on the output shaft of the electric push rod 49. The pressing plate 410 is located between two groups of C-shaped plates 41. Grooves and multiple arc grooves are arranged on the bottom end surface of the pressing plate 410. A pressure sensor is arranged in the groove, and the arc groove is connected to a vacuum pump through a hose.

[0022] As Figure 1 、 2 As shown in FIGS. 2 and 3, a driving block 5 is arranged at the end of the screw rod 44, and the screw rod 44 is screwed and fixed with the screw tube 45. The screw rod 44 can be conveniently rotated through the driving block 5.

[0023] In this embodiment, the C-shaped plate 41 is suspended above the machine table 1, and the distance between the bottom of the C-shaped plate 41 and the top end of the machine table 1 is 0.1 - 0.2 cm. This prevents the C-shaped plate 41 from contacting the top of the machine table 1 and causing severe friction with the top surface of the machine table 1 when it moves.

[0024] As Figure 2 、3 As shown, there are multiple groups of arc-shaped grooves 6 axially arranged on the outer side wall of the U-shaped plate 41, and a rubber protective layer is also arranged on the outer side wall of the U-shaped plate 41. The contact area between it and the side wall of the LED light source board is reduced through the arc-shaped grooves 6, and the friction between the two is reduced.

[0025] In this embodiment, the number of the limiting rods 43 is not less than two groups. Among them, multiple groups of limiting rods 43 are fixedly connected to the inner side wall of the vertical end of the U-shaped plate 41. A roller group that abuts against the top surface of the machine table 1 is also arranged at the bottom of one end of the limiting rod 43. The roller group is arranged at the bottom of the limiting rod 43 close to the side wall of the vertical end of the U-shaped plate 41. The roller group plays a role in supporting and fixing components such as the U-shaped plate 41 to improve its stability. When components such as the U-shaped plate 41 move, the roller group will be driven to slide on the top of the machine table 1, so as to facilitate its movement.

[0026] The usage method of the present invention: Adjust the distance between the two groups of limiting mechanisms 4 according to the width of the LED light source board. The specific steps are to rotate the screw rod 44 so that it rotates in the screw tube 45 and on the rolling bearing 46, and then drive the U-shaped plate 41 to move, so as to expand or reduce the distance between the two U-shaped plates 41. At this time, the U-shaped plate 41 drives the limiting rod 43 to slide in the through hole, preventing the U-shaped plate 41 from rotating or swinging together with the screw rod 44;

[0027] When the U-shaped plate 41 moves, it will drive the pressing plate 410 to displace through the fixing plate 47, the L-shaped frame 48, and the electric push rod 49, so that the pressing plate 410 is always located at the edge of the area between the two U-shaped plates 41. Then, after placing the LED light source board between the two U-shaped plates 41 for clamping and fixing, the electric push rod 49 can drive the pressing plate 410 to move down, so that the pressing plate 410 is located at the blank area on both sides of the top edge of the LED light source board;

[0028] When the pressing plate 410 squeezes and fixes the LED light source board, it will drive the pressure sensor to contact the top surface of the LED light source board to detect the pressure it receives, preventing the pressing plate 410 from moving down excessively and causing extrusion damage to the LED light source board. Then, the LED light source board can be cut by the cutting knife group. When the processing is completed and the pressing plate 410 is driven to move up by the electric push rod 49, the arc-shaped groove can be evacuated through the vacuum pump and the hose to adsorb and fix the LED light source board to the bottom of the pressing plate 410. Then, when the pressing plate 410 moves up, it will drive the LED light source board to slide out upward from between the two U-shaped plates 41, so as to facilitate the removal of the LED light source board from between the two U-shaped plates 41.

[0029] The above has described the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
