Description

Technical Field

[0001] The present invention relates to the technical field of lamp cutting, and more particularly to a cutting device for processing a floodlight. Background Art

[0002] A floodlight is a lighting fixture that can focus light on a specific area to provide bright lighting effects. By adjusting the angle and position of the lamp, different lighting effects can be achieved, and the uniformity and brightness of the lighting can be improved. It is mainly used for architectural decorative lighting and commercial space lighting.

[0003] Floodlights are generally composed of an aluminum shell, a bracket, tempered glass, an aluminum substrate, a reflector, an LED lamp, a power supply, etc. The aluminum shell is formed by die-casting. In order to dissipate heat, a heat sink is usually provided on the back of the aluminum shell. For some high-power floodlights, more and denser heat sinks need to be provided on the back of the aluminum shell, and a control box needs to be installed. The control box is used to install the power supply, circuit board, etc., and has functions such as short circuit, overload, and over-temperature protection.

[0004] The control box is usually installed on the back of the aluminum shell by bolts. In order to avoid disassembling the entire floodlight during installation and maintenance, some floodlights will choose to weld internal threaded columns on the back of the aluminum shell, and then install the control box on the threaded columns by bolts. In this way, the control box can be directly installed or removed on the back of the aluminum shell without removing the parts of the floodlight body.

[0005] However, since the heat sinks are densely packed, the space between the heat sinks is insufficient for welding the threaded columns. Therefore, a portion of the heat sink where the threaded columns are installed needs to be cut off. The current method is to use a shearing tool to extend between the heat sinks for cutting. However, when the shearing tool cuts the root of the heat sink, the tool edge can only be flush. If the root part is cut directly, the cutting edges are likely to touch each other and cause collapse. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Refer to the instruction manual Figure 9-10 The floodlight includes a lamp body 100, a control box 101 and a bracket 102. The control box 101 and the bracket 102 are installed on the back of the lamp body 100. Specifically, the two ends of the bracket 102 are rotated on both sides of the control box 101 through screws and gaskets. There are more heat sinks 103 on the back of the lamp body 100. Before installing the control box 101, it is necessary to use a cutting device to cut the heat sink 103. Fig.10As shown, four installation positions 104 are cut out, and then internal threaded columns 105 are welded at the four installation positions 104 , and then the control box 101 is installed on the internal threaded columns 105 by bolts.

[0033] Refer to the instruction manual Figure 1-Figure 8 A cutting device for processing a floodlight is used to cut a mounting position 104 on a heat sink 103 on the back of a lamp body 100. In order to prevent the blades from collapsing due to contact with each other, the two cutters are first brought as close as possible but not touching each other during cutting, so that only a dent is cut on a part of the material and the material is not completely cut. Then the material to be cut is pushed back and forth to push it back and forth, thus preventing the blade from collapsing.

[0034] Specifically, the cutting device includes a base 1, a working platform 5 is installed on the base 1, and the working platform 5 is used to carry the lamp body 100. A mounting frame 11 is installed above the base 1, and a moving mechanism 2 is installed on the mounting frame 11. A fixed shaft 3 is installed at the output end of the moving mechanism 2, and a cutting mechanism 4 is installed at the lower end of the fixed shaft 3; the cutting mechanism 4 includes a mounting plate 40, and the mounting plate 40 is fixedly installed at the bottom of the fixed shaft 3. A right cutting knife 42 is fixedly installed at one end of the bottom of the mounting plate 40, and a left cutting knife 41 is slidably connected to the other end of the bottom of the mounting plate 40. The side of the left cutting knife 41 close to the right cutting knife 42 has a bevel edge 411, a straight cutting edge 412 and a bevel edge 413 from top to bottom. A driving assembly 44 is installed on the fixed shaft 3. The driving assembly 44 is used to drive the left cutting knife 41 to approach the right cutting knife 42 to cut the heat sink 103 on the lamp body 100. When cutting, the bevel edge 413 is flush with the bottom of the heat sink 103. A push plate 43 is provided on the inner side of the right cutting knife 42. The push plate 43 moves synchronously with the left cutting knife 41 to push the cut part of the heat sink 103.

[0035] In the above technical solution, the moving mechanism 2 includes a Y-axis moving device and a Z-axis moving device. The Y-axis moving device and the Z-axis moving device can adopt a linear motor, a screw-nut mechanism, etc., so that the Y-axis moving device and the Z-axis moving device constitute a two-axis moving mechanism for driving the fixed axis 3 and the cutting mechanism 4 to move along the Y-axis and the Z-axis.

[0036] Specifically, Figure 6-Figure 8 As shown, the driving assembly 44 includes a turntable 441, which is rotatably mounted on the fixed shaft 3. An eccentric annular groove 442 is provided at the bottom of the turntable 441. A rotating driving component 443 is installed on the fixed shaft 3. The output end of the rotating driving component 443 is transmission-connected to the turntable 441. The upper end of the left cutting knife 41 is fixedly connected to a guide shaft 414, and the guide shaft 414 slides inside the eccentric annular groove 442.

[0037] It should be noted that, during cutting, the left cutting knife 41 is driven to approach the right cutting knife 42 by the driving assembly 44, and the rotating driving component 1 443 drives the turntable 441 to rotate through the gear set. During the rotation of the turntable 441, the guide shaft 414 slides inside the eccentric annular groove 442. Since the eccentric annular groove 442 and the turntable 441 are not coaxial, the turntable 441 can drive the guide shaft 414 to move along the radial direction of the turntable 441, so that the left cutting knife 41 can be moved close to or away from the right cutting knife 42. When it is close to the right cutting knife 42, it is used to cut the heat sink 103. Among them, the rotating driving component 1 443 adopts a reduction motor.

[0038] Specifically, Figure 5-Figure 8 As shown, the driving assembly 44 also includes a transmission assembly 45, which includes a connecting rod 1 451, which is fixedly connected to the upper end of the left cutting knife 41, and a connecting rod 2 452 is fixedly connected to one side of the push plate 43, and the connecting rod 2 452 is connected to the connecting rod 1 451.

[0039] In this embodiment, the implementation method is as follows: during processing, first, the lamp body 100 is placed on the working platform 5, and then the moving mechanism 2 drives the fixed axis 3 and the cutting mechanism 4 to move to the position where cutting is required, such as Figure 8As shown, the left cutting blade 41 and the right cutting blade 42 are respectively located on both sides of the heat sink 103, and the end surface of the right cutting blade 42 is pressed on the side wall of the heat sink 103, which can prevent the uncut part of the heat sink 103 from bending and deforming during cutting. Then, the rotating drive component 1443 drives the turntable 441 to rotate, and the turntable 441 drives the guide shaft 414 and the left cutting blade 41 to move toward the direction close to the right cutting blade 42. The bevel edge 411 first contacts the heat sink 103, and interacts with the inner edge of the right cutting blade 42 to cut (shearing mode) the heat sink 103. Then, the straight cutting edge 412 contacts the heat sink 103 to cut the heat sink 103. The state after cutting is: the heat sink 103 contacting the bevel edge 411 is cut off and enters the inner side of the right cutting blade 42, and the heat sink 103 contacting the straight cutting edge 412 and the bevel edge 1413 is only cut with a dent. Furthermore, the left cutting knife 41 is driven to move back and forth by the driving component 44. When the left cutting knife 41 moves to the left, it disengages from the heat sink 103, and the left cutting knife 41 drives the push plate 43 to move to the left synchronously with the left cutting knife 41 through the connecting rod 1 451 and the connecting rod 2 452. At this time, the push plate 43 will push the cut part of the heat sink 103 to the left. When the left cutting knife 41 moves to the right, the bevel edge 411 will push the heat sink 103 to the right. After several reciprocating movements, the heat sink 103 can be pushed back and forth, and the part of the heat sink 103 where only the dents are cut will produce metal fatigue and break. In this way, the cutting is completed. After completion, the two left cutting knives 41 approach each other to keep the cut heat sink 103 waste in the right cutting knife 42, and then the moving mechanism 2 drives the fixed shaft 3 and the cutting mechanism 4 to move upward and then discharge the waste.

[0040] The above technical solution firstly moves the left cutting knife 41 close to the right cutting knife 42, so that the bevel edge 411 cuts off most of the heat sink 103 from top to bottom, and then cuts a dent on the bottom of the heat sink 103 through the straight cutting edge 412 and the bevel edge 413. Since only the dent is cut, the bottoms of the left cutting knife 41 and the right cutting knife 42 do not touch each other, thereby avoiding the problem of collapse. Finally, the heat sink 103 is pushed by using the push plate 43 to move synchronously with the left cutting knife 41, so that the bottom of the heat sink 103 produces metal fatigue and breaks, thereby completing the cutting.

[0041] Furthermore, when the left cutting blade 41 and the right cutting blade 42 are closest to each other, the distance between the front end of the bevel cutting edge 1 413 and the bottom of the right cutting blade 42 is less than the thickness of the heat sink 103 and is not zero.

[0042] The purpose of the above technical solution is to make the straight cutting edge 412 and the bevel cutting edge 413 only cut out a dent, but not directly cut off the heat sink 103 at that position, causing the bevel cutting edge 413 to collide with the right cutting knife 42 and produce a chipping problem.

[0043] Furthermore, a second bevel cutting edge 421 is provided on the bottom side of the right cutting knife 42 close to the left cutting knife 41 , the second bevel cutting edge 421 is horizontally aligned with the straight cutting edge 412 , and the front end of the second bevel cutting edge 421 is flush with the side wall of the right cutting knife 42 close to the left cutting knife 41 .

[0044] It should be noted that the purpose of providing the second bevel cutting edge 421 is to support the bottom of the side wall of the heat sink 103 so that the first bevel cutting edge 413 can cut a dent.

[0045] Refer to the instruction manual Figure 5-Figure 8 It should be noted that when cutting the heat sink 103, since the bottom of the heat sink 103 is not completely broken, the push plate 43 is best to push the upper end of the heat sink 103. However, when discharging the waste, if the bottom of the waste is stuck in the right cutting knife 42, the push plate 43 cannot be pushed to the bottom of the heat sink 103. Therefore, the waste may not be discharged. Therefore, the following technical solution is proposed: a linear drive component 46 is fixedly mounted on the fixed shaft 3, and the output end of the linear drive component 46 is fixedly connected to a connecting rod 3 461, and the bottom of the connecting rod 3 461 is horizontally movably sleeved on the connecting rod 2 452, and the connecting rod 2 452 is vertically movably plugged into the connecting rod 1 451.

[0046] It should be noted that the linear driving component 1 46 drives the connecting rod 2 452 to move downward through the connecting rod 3 461, and the connecting rod 2 452 moves downward relative to the connecting rod 1 451, thereby driving the push plate 43 to move downward, so that the push plate 43 contacts the bottom of the heat sink 103, so that the heat sink 103 can be pushed out from the right cutting knife 42 for easy discharge. Among them, the linear driving component 1 46 can be a cylinder, an electromagnet, etc. Since the required force is not large, it is best to use an electromagnet to reduce costs.

[0047] The above technical solution sets a linear drive component 46 and a connecting rod 3 461 to drive the push plate 43 to move downward when discharging waste, so that the push plate 43 can push the bottom of the waste, thereby preventing the bottom of the waste from being stuck in the right cutting knife 42 and unable to be discharged.

[0048] Refer to the instruction manual Figure 1-Figure 4 A moving platform 7 is arranged on the upper surface of the working platform 5, and a linear driving component 6 is installed on the lower surface of the working platform 5. The output end of the linear driving component 6 is fixedly connected to the moving platform 7, and both ends of the moving platform 7 are rotatably connected with a plurality of pressure wheels 71.

[0049] Furthermore, a movable plate 72 is provided at one end of the movable platform 7, a movable shaft 73 is installed on one side of the movable plate 72, the movable shaft 73 is plugged into the movable platform 7, an elastic component 74 is sleeved on the outer side of the movable shaft 73, and both ends of the elastic component 74 are respectively pressed with the movable platform 7 and the movable plate 72, and the pressure wheel 71 close to one end of the movable plate 72 is rotatably connected to the movable plate 72.

[0050] Furthermore, a conveyor belt 9 is provided on one side of the front end of the working platform 5. When the movable platform 7 moves to one end of the rotating driving component 28, the rotating driving component 28 conveys the lamp body 100 to between the pressure wheels 71 at both ends of the movable platform 7, so that the pressure wheels 71 clamp the lamp body 100.

[0051] It should be noted that the linear drive component 2 6 can adopt a screw nut device to drive the mobile platform 7 to move back and forth on the working platform 5. When loading is required, the linear drive component 2 6 moves the mobile platform 7 to one end of the conveyor belt 9, and then conveys the lamp body 100 between the pressure wheels 71 at both ends of the mobile platform 7 through the conveyor belt 9. When entering, the elastic component 74 is compressed, so that the pressure wheel 71 can clamp the lamp body 100. The purpose of setting the pressure wheel 71 is to reduce the friction between the side wall of the lamp body 100 and reduce noise. Among them, the elastic component 74 is a compression spring.

[0052] It is also necessary to explain that a cylinder may be provided on one side of the conveyor belt 9 , and the lamp body 100 conveyed on the conveyor belt 9 may be pushed between the two pressure discharge wheels 71 by means of the cylinder.

[0053] Furthermore, a second rotating driving component 8 is fixedly installed on one side of the rear end of the working platform 5 , and a waste box 81 is fixedly installed on the output end of the second rotating driving component 8 . The waste box 81 is used to store waste generated by cutting the heat sink 103 .

[0054] It should be noted that after the cutting is completed, when the waste is discharged, the waste box 81 is first driven to rotate by the rotating drive component 8, so that the front end of the waste box 81 is rotated to the bottom of the cutting mechanism 4. After the cutting mechanism 4 discharges the waste into the waste box 81, the rotating drive component 8 drives the waste box 81 to rotate out from the bottom of the cutting mechanism 4, which does not affect the subsequent cutting operation. The rotating drive component 8 is a reduction motor.

[0055] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
