The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] Reference Figures 1 to 6 As shown, a stripping device for an LED bracket bending machine disclosed in the present invention includes a control box 100, a slide rail 200, a lower template 300, a first drive assembly (not shown in the drawings), an upper template 500, a second drive assembly 600, a vacuum adsorption device 700, a gas compressor 800, and an image control device (not shown in the drawings).

[0030] The slide rail 200 is mounted on the top surface of the control box 100. The lower mold plate 300 is slidably mounted on the slide rail 200. The lower mold plate 300 is provided with a pressing groove 310 that matches the LED bracket and a collection chamber 320 that communicates with the pressing groove 310. The first drive assembly is fixedly mounted on the control box 100. During use, the first drive assembly drives the lower mold plate 300 to slide on the slide rail 200, placing the LED bracket into the pressing groove 310 and moving the lower mold plate 300 loaded with the LED bracket to the mold closing position. The LED bracket is loaded with a large number of LED chips. The upper mold plate 500 is movably mounted on the control box 100. The upper mold plate 500 is provided with a sizing block 510 that matches the pressing groove 310 and a flow chamber 520. When the upper mold plate 500 and the lower mold plate 300 are closed, the shaping block 510 extends into the pressing groove 310, bending the pins of the LED chip on the LED bracket and peeling the LED chip from the LED bracket. The LED chip then falls into the pressing groove 310. The upper mold plate 500 and the lower mold plate 300 are then separated, and the LED chips in the pressing groove 310 are collected before the next step. The flow chamber 520 is equipped with at least one air nozzle 521, which is facing the pressing groove 310.

[0031] The second drive assembly 600 is provided on the control box 100. When in use, the second drive assembly 600 drives the upper template 500 to reciprocate up and down relative to the lower template 300, so that the upper template 500 approaches the lower template 300 when moving downward until the shaping block 510 extends into the pressing groove 310, and the upper template 500 separates from the lower template 300 when moving upward.

[0032] The vacuum adsorption device 700 is connected to the collection chamber 320 via an air pipe. The vacuum adsorption device 700 generates a negative pressure, allowing air to flow sequentially from the compression groove 310, the collection chamber 320, and the air pipe into the vacuum adsorption device 700. The airflow carries debris from the compression groove 310 along with it. The collection chamber 320 acts as a buffer, allowing air to flow into the air pipe connected to the vacuum adsorption device 700 in an orderly manner, preventing the air pipe from becoming blocked.

[0033] The gas compressor 800 is connected to the overflow chamber 520 via an air pipe. The gas compressor 800 generates high-speed, high-pressure gas, which is sequentially blown through the air pipe, the overflow chamber 520, and the air nozzle 521 to purge the sizing block 510. It should be noted that after collecting the LED chips in the pressing groove 310, the upper mold plate 500 and the lower mold plate 300 can be closed. Since the space between the upper mold plate 500 and the lower mold plate 300 is relatively closed, the gas compressor 800 can also be used to pass high-speed, high-pressure gas into the pressing groove 310 at this time, so that the high-speed, high-pressure gas simultaneously blows the inner wall of the pressing groove 310 and the surface of the sizing block 510.

[0034] The image control device is electrically connected to the first drive component, the second drive component 600, the vacuum adsorption device 700, and the gas compressor 800. The image control device is used to collect images of the pressing groove 310 and the forming block 510. When the image control device determines that there is debris in the collected images of the pressing groove 310 and the forming block 510 and it affects the next step of bending and stripping, it controls the vacuum adsorption device 700 and the gas compressor 800 to operate. In addition, the relative position between the upper template 500 and the lower template 300 during purging and vacuum adsorption can also be adjusted by controlling the operation of the first drive component and the second drive component 600.

[0035] In this embodiment, the first driving component may be a telescopic cylinder, a telescopic motor or the like, or a linear motor.

[0036] In some embodiments of the present invention, Figure 2 As shown, the second drive assembly 600 includes a column 610, a base 620, and a telescopic motor 630. Multiple columns 610 are provided, with one end of each column 610 fixedly mounted on the control box 100. The base 620 is located at the other end of each column 610, so that the base 620 is suspended above the control box 100 by the columns 610. The telescopic motor 630 is fixedly mounted on the base 620, and the telescopic shaft of the telescopic motor 630 is connected to the upper template 500. When the telescopic motor 630 is in operation, the telescopic movement of the telescopic motor 630 synchronously drives the upper template 500 to move up and down.

[0037] In some embodiments of the present invention, Figure 2 As shown, the second drive assembly 600 further includes a guide base 640, which is fixedly mounted on the control box 100. The upper template 500 is slidably mounted on the guide base 640. When the telescopic motor 630 synchronously drives the upper template 500 to move up and down, the guide base 640 acts as a position limiter and guide for the upper template 500, ensuring smoother up and down movement of the upper template 500.

[0038] In some embodiments of the present invention, a brush assembly is provided in the pressing groove 310, which is used to clean the inner wall of the pressing groove 310, and when the upper template 500 and the lower template 300 are molded together, the brush assembly is used to clean the inner wall of the pressing groove 310 and the surface of the forming block 510, so that the debris on the inner wall of the pressing groove 310 and the surface of the forming block 510 are detached and fall into the pressing groove 310, thereby preventing the vacuum adsorption device 700 and the gas compressor 800 from being unable to completely clean the attached debris when acting alone, and then the debris in the pressing groove 310 is sucked away by the vacuum adsorption device 700.

[0039] In some embodiments of the present invention, the lower template 500 is provided with a chute (not shown in the accompanying drawings). It should be noted that the chute should be positioned so as not to interfere with the bending and stripping operations of the LED chips. Specifically, the brush assembly includes a brush body (not shown in the accompanying drawings), bristles (not shown in the accompanying drawings), and a third drive assembly (not shown in the accompanying drawings). The brush body slides within the chute, the bristles are attached to the brush body, and the third drive assembly is located on the lower template 500 and is in transmission connection with the brush body. When the third drive assembly is activated, it drives the brush body to slide within the chute, causing the bristles to move and remove debris adhering to the inner wall of the pressing groove 310 and the surface of the shaping block 510.

[0040] In some embodiments of the present invention, the image control device includes a first camera, a second camera, and a control unit. The first camera is used to capture an image of the pressing groove 310, and the second camera is used to capture an image of the shaping block 510. The control unit is electrically connected to the first camera, the second camera, the first drive assembly, the second drive assembly 600, the third drive assembly, the vacuum adsorption device 700, and the gas compressor 800. After receiving the image information captured by the first and second cameras, the control unit processes the image information and determines whether the amount and size of debris attached to the inner wall of the pressing groove 310 and the surface of the shaping block 510 will affect the bending and stripping operation of the LED chip. If so, the control unit controls the vacuum adsorption device 700, the gas compressor 800, and the third drive assembly to operate according to a specific workflow. Of course, the control unit can also adjust the relative position between the upper template 500 and the lower template 300 during purging and vacuum adsorption by controlling the operation of the first and second drive assemblies 600.

[0041] In some embodiments of the present invention, a receiving cavity (not shown in the drawings) is provided in the control box 100 , and the control unit is disposed in the receiving cavity, which serves to physically protect and electrically insulate the control unit.

[0042] In some embodiments of the present invention, Figure 1 As shown, a start switch 110 is provided on the side wall of the control box 100 , and the start switch 110 is electrically connected to the control unit. The operator presses the start switch 110 to perform the bending and stripping operation of the LED chip.

[0043] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, an emergency stop switch 120 is provided on the side wall of the control box 100. The emergency stop switch 120 is electrically connected to the control unit. When an emergency occurs, the operator can press the emergency stop switch 120 to stop the bending and stripping operation of the LED chip.

[0044] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the stripping device of the LED bracket bending machine further includes a shielding cover 900, which is provided on the column 610 and is arranged around the upper template 500. By providing the shielding cover 900, on the one hand, it can prevent foreign objects from touching the moving upper template 500, and on the other hand, it can prevent debris from splashing when the gas compressor 800 is working.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
