[0021] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0022] The following describes the LED lead cutting device according to the embodiment of the present application in conjunction with the accompanying drawings.

[0023] like Figure 1-Figure 5 As shown, the pin cutting device of the light-emitting diode of the embodiment of the present application may include a support frame 1, a vibrating feeder 2, a limiting bracket 3, a cutting box 4, a material control component 5, a pressing component 6, a material blocking component 7 and a cutting component 8.

[0024] The vibrating feeder 2 is arranged on the support frame 1 , and a feeder frame 20 is arranged on the vibrating feeder 2 .

[0025] It should be noted that the vibration blanking machine 2 described in this embodiment is a common vibration blanking equipment on the market, which can load and unload multiple light-emitting diodes vertically upwards and with the pins downwards from the blanking rack 20, thereby ensuring continuous loading of the light-emitting diodes and improving the efficiency of cutting the pins of the light-emitting diodes.

[0026] The limiting bracket 3 is tiltedly arranged on the cutting box 4 , and one end of the limiting bracket 3 is connected to the unloading rack 20 .

[0027] It can be understood that, through the setting of the limiting bracket 3, the light-emitting diodes on the blanking rack 20 can continue to be limited and blanked by vibration, and through the inclined setting of the limiting bracket 3, multiple limited light-emitting diodes can be continuously blanked by vibration, thereby ensuring the continuous loading of the light-emitting diodes and improving the efficiency of the pin cutting of the light-emitting diodes.

[0028] A limiting groove 40 is provided on the cutting box body 4 , and the other end of the limiting bracket 3 is communicated with the limiting groove 40 .

[0029] It should be noted that a feed trough 32 is provided on the limit bracket 3 described in this example, and the feed trough 32 is connected to the limit groove 40, so that the light-emitting diode is vibrated and fed from the feed frame 20 of the vibrating feeder 2 to the feed trough 32 of the limit bracket 3, and then fed from the limit bracket 3 to the limit groove 40 of the cutting assembly 8, so that the cutting assembly 8 works to cut the pins of the light-emitting diode that is limited in the limit groove 40.

[0030] The material control component 5 , the pressing component 6 and the material blocking component 7 are respectively arranged on the cutting box 4 , the material control component 5 is located on one side of the limiting bracket 3 , the pressing component 6 is located above the limiting groove 40 , and the material blocking component 7 is located on the other side of the limiting groove 40 .

[0031] It is understandable that the material control component 5 is used to control the light-emitting diodes on the limiting bracket 3 to prevent excessive accumulation of light-emitting diodes and affect the cutting quality of the cutting component 8.

[0032] It can be understood that the pressing assembly 6 is used to press the pins of the light emitting diode to be cut on the limiting groove 40, so as to ensure the cutting quality of the pins of the light emitting diode.

[0033] It can be understood that the material blocking assembly 7 is used to block the light-emitting diodes on the limiting groove 40, thereby preventing excessive feeding of the light-emitting diodes and causing the uncut light-emitting diodes to leak into the receiving box (not shown in the figure) next to the cutting box 4, thereby ensuring the cutting quality of the pins of the light-emitting diodes.

[0034] The cutting assembly 8 is disposed in the cutting box 4 , and the cutting assembly 8 may include a motor 80 , a support plate 81 , a moving disk 82 , a linkage rod 83 , a linkage seat 84 , a cutting tool 85 and an abutment seat 86 .

[0035] Wherein, the motor 80 and the support plate 81 are respectively arranged in the cutting box 4;

[0036] The moving disk 82 is rotatably set on the support plate 81, and the output shaft of the motor 80 is fixedly connected to the eccentric side of the moving disk 82. One end of the interlocking control rod 83 is set on the moving disk 82 and is located on the side away from the output shaft of the motor 80. The other end of the interlocking control rod 83 is slidably connected to the linear slide groove 840 opened on the interlocking control seat 84. The interlocking control seat 84 is slidably set on the cutting box 4. The cutting tool is set on the interlocking control seat 84 and slidably abuts with the abutment seat 86. The abutment seat 86 is set on the cutting box 4.

[0037] It can be understood that, through the linear slide groove 840 opened on the joint control seat 84, the moving disk 82 drives the joint control rod 83 to rotate in a circle, and the joint control rod 83 is slidably connected to the linear slide groove 840, and when the joint control rod 83 rotates in a circle, it is limited by the linear slide groove 840, so that the circular motion of the joint control rod 83 is converted into the reciprocating linear motion of the joint control seat 84 on the cutting box 4, thereby ensuring the cutting of the pins of the light-emitting diode.

[0038] It can be understood that, through the fixed connection between the output shaft of the motor 80 and the eccentric side of the moving disk 82 and the arrangement of one end of the interlocking control rod 83 on the moving disk 82 and on the side away from the output shaft of the motor 80, the output shaft of the motor 80 rotates to drive the moving disk 82 to rotate, thereby driving the interlocking control rod 83 to rotate, causing the interlocking control rod 83 to rotate, and driving the interlocking control seat 84 and the cutting tool 85 to move back and forth in the cutting box 4, and intermittently abut against the abutment seat 86, and when the cutting tool 85 abuts against the abutment seat 86, the pins of the light-emitting diode can be cut, thereby realizing the pin cutting of the light-emitting diode.

[0039] Specifically, in the actual operation process, the relevant staff pours multiple light-emitting diodes into the vibrating feeder 2, and the controller (not shown in the figure) controls the vibrating feeder 2 to perform work vibration, so that the multiple light-emitting diodes are sequentially discharged from the feed rack 20 in an orderly manner, and the feed rack 20 limits the position of each light-emitting diode. Multiple light-emitting diodes are discharged from the feed rack 20 to the limiting bracket 3, and the controller controls the material control component 5 to control the quantity of the discharged light-emitting diodes, and controls the material blocking component 7 to block the discharged light-emitting diodes, so that the discharge of the fixed cutting number of light-emitting diodes is prevented, thereby preventing excessive discharge of light-emitting diodes, affecting the cutting quality of the cutting component 8, or excessive discharge causing the discharge to be pushed without cutting.

[0040] A fixed number of LEDs are then loaded and unloaded from the limiting bracket 3 into the limiting groove 40 on the cutting box 4, and the controller controls the pressing component 6 to press and limit the LEDs in the limiting groove 40, thereby ensuring the cutting quality of the LED pins.

[0041] The controller then controls the motor 80 to rotate, the motor 80 drives the moving disk 82 to rotate in a circle, the moving disk 82 drives the interlocking rod 83 to move in a circle, the interlocking rod 83 drives the interlocking seat 84 to move toward the abutting seat 86 in the cutting box 4, thereby driving the cutting tool 85 to abut and cut with the pin and the abutting seat 86, thereby cutting the pin of the light-emitting diode in the limiting groove 40. After the cutting is completed, the motor 80 continues to rotate to drive the other components of the cutting assembly 8 to reset, the controller controls the material control assembly 5, the pressing assembly 6 and the material blocking assembly 7 to reset, so that the next batch of light-emitting diodes are unloaded into the limiting groove 40, and the above operation is repeated, thereby completing the continuous cutting of the light-emitting diode pins and improving the cutting efficiency of the pins. In addition, when unloading the next batch of light-emitting diodes, the light-emitting diodes whose pins have been cut can be pushed to unload.

[0042] In one embodiment of the present application, Figure 1 and Figure 2As shown, the limiting bracket 3 may include a first limiting plate 30 and a second limiting plate 31, one end of the first limiting plate 30 and the second limiting plate 31 are respectively connected to the cutting box 4, the other ends of the first limiting plate 30 and the second limiting plate 31 are respectively connected to the unloading rack 20, and the first limiting plate 30 and the second limiting plate 31 are symmetrically arranged to form a unloading trough 32, and the unloading trough 32 is connected to the limiting groove 40.

[0043] It should be noted that the unloading rack 20 described in this embodiment is provided with two ports, so that one end of the first limiting plate 30 is connected to one port, and one end of the second limiting plate 31 is connected to the other port, thereby ensuring the unloading effect of the light-emitting diode.

[0044] In one embodiment of the present application, Figure 1-Figure 3 As shown, the material control assembly 5 may include a support block 50 , a first electric telescopic rod 51 , a material control plate 52 and a counting sensor 53 .

[0045] Among them, the support block 50 is arranged on the cutting box 4 and is located on one side of the limit bracket 3, the first electric telescopic rod 51 is arranged on the support block 50, the extension axis of the first electric telescopic rod 51 is connected to the material control plate 52, the material control plate 52 is slidably connected to the top of the support frame 1, and the counting sensor 53 is arranged on the support block 50 and is located above the limit bracket 3.

[0046] It should be noted that the counting sensor 53 described in this example is a common sensor on the market and will not be described in detail here.

[0047] In one embodiment of the present application, Figure 3 As shown, the pressing assembly 6 may include a pressing frame 60 , a second electric telescopic rod 61 and a pressing plate 62 .

[0048] Among them, the pressing frame 60 is arranged on the cutting box 4 and is located above the limiting groove 40. The second electric telescopic rod 61 is arranged on the pressing frame 60. The extension axis of the second electric telescopic rod 61 is connected to the pressing plate 62. The pressing plate 62 is located at the bottom of the pressing frame 60.

[0049] It can be understood that, by disposing the pressing plate 62 , the light emitting diode can be pressed and limited, thereby ensuring the cutting quality of the pins of the light emitting diode.

[0050] In one embodiment of the present application, Figure 3 As shown, the material blocking assembly 7 may include a third electric telescopic rod 70 and a material blocking plate 71 .

[0051] Among them, the third electric telescopic rod 70 is arranged on the cutting box 4 and is located on one side of the limiting groove 40, and the extension shaft of the third electric telescopic rod 70 is connected to the baffle plate 71, and the baffle plate 71 is slidably arranged above the cutting box 4.

[0052] It is understandable that, by providing the blocking plate 71 , the light emitting diodes at the limiting grooves 40 can be blocked to prevent leakage of the light emitting diodes whose pins have not been cut, thereby ensuring the efficiency of cutting the pins of the light emitting diodes.

[0053] Specifically, in the actual operation process, the relevant staff pours multiple light-emitting diodes into the vibrating feeder 2, and the controller (not shown in the figure) controls the vibrating feeder 2 to perform work and vibration, so that the multiple light-emitting diodes are sequentially discharged from the feed rack 20 in an orderly manner, and the feed rack 20 limits the position of each light-emitting diode, and multiple light-emitting diodes are discharged from the feed rack 20 to the limiting bracket 3, and the controller controls the counting sensor 53 to perform work, so as to count the light-emitting diodes that have been discharged to the limiting groove 40. After reaching a certain number, the controller controls the first electric telescopic rod 51 to extend, and drives the material control plate 52 to extend, so as to block the discharge of the light-emitting diodes on the feed slot 32, and the controller controls the third electric telescopic rod 70 to extend, and drives the material blocking plate 71 to move to the light-emitting diodes at the limiting groove 40 for limiting and blocking, so that it discharges a fixed number of light-emitting diodes for cutting, to prevent excessive discharge of light-emitting diodes, affecting the cutting quality of the cutting component 8, or excessive discharge causing the discharge to be pushed without cutting.

[0054] A fixed number of light-emitting diodes are then loaded and unloaded from the limiting bracket 3 into the limiting groove 40 on the cutting box 4, and the controller controls the second electric telescopic rod 61 to extend and drive the pressing plate 62 to move downward, thereby pressing and limiting the light-emitting diodes in the limiting groove 40, thereby ensuring the cutting quality of the pins of the light-emitting diodes.

[0055] The controller then controls the motor 80 to rotate, the motor 80 drives the moving disk 82 to rotate in a circle, the moving disk 82 drives the interlocking rod 83 to move in a circle, the interlocking rod 83 drives the interlocking seat 84 to move toward the abutting seat 86 in the cutting box 4, thereby driving the cutting tool 85 to abut and cut with the pin and the abutting seat 86, thereby cutting the pin of the light-emitting diode in the limiting groove 40. After the cutting is completed, the motor 80 continues to rotate to drive the other components of the cutting assembly 8 to reset, the controller controls the material control assembly 5, the pressing assembly 6 and the material blocking assembly 7 to reset, so that the next batch of light-emitting diodes are unloaded into the limiting groove 40, and the above operation is repeated, thereby completing the continuous cutting of the light-emitting diode pins and improving the cutting efficiency of the pins. In addition, when unloading the next batch of light-emitting diodes, the light-emitting diodes whose pins have been cut can be pushed to unload.

[0056] In summary, the LED pin cutting device according to the embodiment of the present application can continuously load and cut the LED pins, thereby improving the LED pin cutting efficiency.
