Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting device technology, specifically a substrate cutting device for component processing. Background Technology
[0002] The cutting device is a key piece of equipment in substrate processing, mainly responsible for cutting and slicing the substrate to form the required shape and contour. This device typically consists of a support frame, a laser cutter, and cylinders. The support frame provides a stable working platform for the entire device, ensuring that the substrate can be placed and moved smoothly during the cutting process.
[0003] In practical applications, existing substrate cutting devices typically consist of a slide rail, a sliding support, a laser cutting head, and a telescopic cylinder. During substrate cutting, the slide rail limits the sliding support, and when the telescopic cylinder pushes the sliding support, the sliding support can only move the laser cutting head horizontally along the outer wall of the slide rail to perform linear cutting on the substrate. Although existing devices ensure precise linear movement of the laser cutting head during substrate cutting, the limitation imposed by the slide rail on the sliding support restricts the laser cutting head to linear cutting. When faced with complex shape cutting requirements, the substrate can only be cut in multiple steps. Therefore, we provide a substrate cutting device for component processing. Utility Model Content

The first lead screws are located at both ends of the outer wall of the first synchronizing rod, and the outer wall of one end of the first synchronizing rod is rotatably connected to the outer wall of one end of the first synchronizing rod through beveled teeth meshing.
[0007] In one of the above, the outer wall of one end of the first lead screw is connected through to one side of the inner wall of the first cutting bracket, and the outer wall of one end of the first lead screw passes through the first cutting bracket and is fixedly connected to the outer wall of the output end of the first motor. The outer wall of one end of the first lead screw is connected through to one side of the outer wall of the first limiting slide, and one end of the outer wall of the first lead screw is rotatably connected to one end of the inner wall of the first limiting slide through a thread.
[0008] As described above, multiple first slide rails are fixedly connected to both sides of the inner wall of the first cutting bracket, and the first slide rails are located at both ends inside the first limiting slide. One end of the outer wall of the first slide rail is connected through to one side of the outer wall of the first limiting slide, and one end of the inner wall of the first limiting slide is slidably connected to one side of the outer wall of the first slide rail.
[0009] As described above, a set of corresponding second lead screws are fixedly connected to both sides inside the second cutting bracket, and the second lead screws are located at both ends inside the second limiting slide. The outer wall of one end of the second lead screw is connected through to the outer wall of one side of the second limiting slide, and the outer wall of the second lead screw is rotatably connected to one end inside the second limiting slide through a thread.
[0010] As described above, the outer wall of the output end of the second motor is connected through one side of the outer wall of the second cutting bracket, and the outer wall of the output end of the second motor is connected through one side of the outer wall of the second cutting bracket and fixedly connected to the outer wall of one end of one of the second lead screws. One end of the outer wall of the second lead screw is rotatably connected to a second synchronizing rod through a bevel gear meshing, and the second synchronizing rod is located inside one side of the second cutting bracket.
[0011] As described above, multiple second slide rails are fixedly connected to both sides of the inner wall of the second cutting bracket, and the second slide rails are located on the outer side of the second lead screw.

[0013] Compared with the prior art, the substrate cutting device for component processing has the following advantages:
[0014] Before cutting the substrate, the operator needs to move the substrate to the center of the top surface of the cutting base plate and then activate the first motor. The first motor drives multiple first lead screws to rotate simultaneously on both sides inside the first cutting bracket. As the first lead screws rotate, they can cooperate with the first slide rail and push the first limiting slide along the outer wall of the first slide rail to move horizontally through their own outer wall threads.

[0015] II. In this utility model, multiple second lead screws in the second cutting bracket pass through one end of the second limiting slide. As the first and second lead screws drive the first and second limiting slides to move in different directions along the first and second slide rails respectively through the external wall threads, under their action, the limiting support and laser cutting head at one end of the bracket can be driven to make various movements such as arcs and straight lines on the top of the cutting base plate, so as to complete the cutting work of complex shapes of the substrate in one go. Thus, through the mutual cooperation of the first lead screw, the second lead screw, the first limiting slide, and the second limiting slide, the laser cutting head can be driven to make various movement trajectories on the top of the substrate, such as arcs and straight lines, and complete the cutting work of complex shapes of the substrate in one go. In this way, the cumbersome steps of cutting the substrate multiple times when facing the cutting requirements of complex shapes of substrates are avoided by traditional devices, and the processing efficiency of cutting substrates is effectively improved while ensuring cutting quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1-5 As shown, this utility model provides a technical solution: a substrate cutting device for component processing, including a first cutting bracket 1 and a second cutting bracket 2. The top outer wall of the first cutting bracket 1 is fixedly connected to the bottom outer wall of the second cutting bracket 2, and a cutting base plate 101 is fixedly connected to the bottom of the first cutting bracket 1. A first motor 102 and a second motor 201 are respectively fixedly connected to one side of the outer wall of the first cutting bracket 1 and the second cutting bracket 2, and the second cutting bracket 1 and the first cutting bracket 2 are both connected to the second motor 102 through the second motor 201. The motor 201 is slidably connected to the limiting support 103. The laser cutting head 104 is fixedly connected to the center of the bottom surface of the limiting support 103. The first cutting bracket 1 has the first motor 102 on both sides inside. The first limiting slide 105 is slidably connected to one side of the first cutting bracket 1 through the first motor 102. The second limiting slide 202 is slidably connected to one side of the second cutting bracket 2 inside. The outer walls of the second limiting slide 202 are slidably connected to one side of the second cutting bracket 2 inside through the output end of the second motor 201.
[0025] Before cutting the substrate, the operator needs to move the substrate to the center of the top surface of the cutting base plate 101 and then activate the first motor 102. The first motor 102 drives multiple first lead screws 106 to rotate simultaneously on both sides inside the first cutting bracket 1. As the first lead screws 106 rotate, they can cooperate with the first slide rail 108 and push the first limiting slide 105 to move horizontally along the outer wall of the first slide rail 108 through their own outer wall threads. Multiple second lead screws 203 in the second cutting bracket 2 pass through one end of the second limiting slide 202. As the first lead screws 106 and second lead screws 203 respectively drive the first limiting slide 105 and the second limiting slide 202 to move in different directions along the first slide rail 108 and the second slide rail 205 through their outer wall threads, the first and second lead screws 206 and second lead screws 203 respectively drive the first limiting slide 105 and the second limiting slide 202 to move in different directions along the first slide rail 108 and the second slide rail 205. Under their action, the limiting support 103 and the laser cutting head 104 at one end of the internal structure can move in various ways, such as arcs and straight lines, on the top of the cutting base plate 101, so as to complete the cutting of the complex shape of the substrate in one go. Thus, through the cooperation of the first lead screw 106, the second lead screw 203, the first limiting slide 105, and the second limiting slide 202, the laser cutting head 104 can be driven to move in various trajectories, such as arcs and straight lines, on the top of the substrate, and complete the cutting of the complex shape of the substrate in one go. In this way, the cumbersome steps of cutting the substrate multiple times when faced with the cutting requirements of the complex shape of the substrate by the traditional device are avoided, and the processing efficiency of cutting the substrate is effectively improved while ensuring the cutting quality.
[0026] like Figure 1 , Figure 4 As shown, multiple first lead screws 106 are rotatably connected to both sides of the interior of the first cutting bracket 1, and a first synchronizing rod 107 is rotatably connected to one side of the interior of the first cutting bracket 1. The first lead screws 106 are located at both ends of the outer wall of the first synchronizing rod 107, and one end of the outer wall of the first synchronizing rod 107 is rotatably connected to the other end of the first synchronizing rod 107 through bevel gear engagement. One end of the outer wall of one of the first lead screws 106 is connected through one side of the inner wall of the first cutting bracket 1, and the other end of the outer wall of the first lead screw 106 passes through the first cutting bracket 1 and is connected to the output end of the first motor 102. The outer wall is fixedly connected, and one end of the outer wall of the first lead screw 106 is connected through to one side of the outer wall of the first limiting slide 105. The outer wall of the first lead screw 106 is rotatably connected to one end of the inner wall of the first limiting slide 105 through a thread. Multiple first slide rails 108 are fixedly connected to both sides of the inner wall of the first cutting bracket 1. The first slide rails 108 are located at both ends inside the first limiting slide 105. One end of the outer wall of the first slide rail 108 is connected through to one side of the outer wall of the first limiting slide 105. The inner end of the first limiting slide 105 is slidably connected to one side of the outer wall of the first slide rail 108.
[0027] Before cutting the substrate, the operator needs to move the substrate to the center of the top surface of the cutting base plate 101 and then activate the first motor 102. Since a first synchronizing rod 107 is provided between the two first lead screws 106, and conical teeth are respectively provided on the outer wall of one end of the first lead screw 106 and the outer walls of both ends of the first synchronizing rod 107, the first lead screw 106 and the first synchronizing rod 107 rotate relative to each other through the meshing transmission between the conical teeth. Furthermore, by placing the first synchronizing rod 107 between the first lead screws 106, the output end of the first motor 102 can simultaneously drive multiple first lead screws 106 inside the first cutting bracket 1 to rotate simultaneously. Multiple first slide rails 108 are provided on both sides, and the first slide rails 108 pass through the first limiting slide 105, so that the first slide rails 108 restrict the movement trajectory of the first limiting slide 105. As the first lead screw 106 rotates inside both sides of the first cutting bracket 1, the first lead screw 106 can cooperate with the first slide rail 108, and push the first limiting slide 105 to move horizontally along the outer wall of the first slide rail 108 through its own outer wall thread. Thus, through the cooperation between the first lead screw 106, the first synchronization rod 107 and the first slide rail 108, the device can drive the laser cutting head 104 to perform complex shape cutting tasks on the substrate in subsequent operations.
[0028] like Figure 1 ,like Figure 2 , Figure 3 and Figure 5 As shown, a set of corresponding second lead screws 203 are fixedly connected to both sides inside the second cutting bracket 2. The second lead screws 203 are located at both ends inside the second limiting slide 202. The outer wall of one end of the second lead screw 203 is connected through to the outer wall of one side of the second limiting slide 202. The outer wall of the second lead screw 203 is rotatably connected to the inner end of the second limiting slide 202 by a thread. The outer wall of the output end of the second motor 201 is connected through to one side of the outer wall of the second cutting bracket 2. The outer wall of the output end of the second motor 201 is also connected through to one side of the outer wall of the second cutting bracket 2 and is fixedly connected to the outer wall of one end of one of the second lead screws 203. The outer wall of the second lead screw 203 is rotatably connected to a second lead screw 203 by a bevel gear meshing. Synchronizing rod 204, and the second synchronizing rod 204 is located inside one side of the second cutting bracket 2. Multiple second slide rails 205 are fixedly connected to both sides of the inner wall of the second cutting bracket 2. The second slide rails 205 are located outside one side of the second lead screw 203. One end of the outer wall of the second slide rail 205 is connected through to one side of the outer wall of the second limiting slide 202. The inner side of the second limiting slide 202 is slidably connected to the inner side of the second slide rail 205. The two sides of the outer wall of the limiting support 103 are respectively connected through to one end of the inner wall of the first limiting slide 105 and the second limiting slide 202. The two sides of the outer wall of the limiting support 103 are simultaneously slidably connected to one end of the inner wall of the first limiting slide 105 and the second limiting slide 202.
[0029] Multiple second lead screws 203 inside the second cutting bracket 2 are respectively inserted through one end of the second limiting slide 202. Multiple second slide rails 205 are fixed on both sides of the second cutting bracket 2. By sliding through the second slide rails 205 and the first end of the second limiting slide 202, the movement trajectory of the second limiting slide 202 is restricted. Since a second synchronizing rod 204 is provided between the second lead screws 203 and they are driven by the meshing of bevel teeth, the multiple second lead screws 203 on both sides of the second cutting bracket 2 can rotate simultaneously on both sides of the second cutting bracket 2 under the drive of the output end of the second motor 201. Since both the second limiting slide 202 and the first limiting slide 105 can limit the limiting support 103 through their own inner walls, the first limiting slide 105 and the second limiting slide 202 are arranged in a cross pattern. As the first lead screw 106 and the second lead screw 203 respectively drive the first limiting slide 105 through their own outer wall threads, the first limiting slide 105 and the second limiting slide 202 are respectively arranged in a cross pattern. The first and second limiting slides 202 move in different directions along the outer walls of the first slide rail 108 and the second slide rail 205. Under the action of the inner walls of the first limiting slide 105 and the second limiting slide 202, the limiting support 103 and the laser cutting head 104 at one end of the inner wall can move in various ways, such as arcs and straight lines, on the top of the cutting base plate 101, so as to complete the cutting of the complex shape of the substrate in one go. Thus, through the cooperation of the first lead screw 106, the second lead screw 203, the first limiting slide 105, and the second limiting slide 202, the laser cutting head 104 can be driven to move in various trajectories, such as arcs and straight lines, on the top of the substrate, and complete the cutting of the complex shape of the substrate in one go. This avoids the tedious steps of cutting the substrate multiple times when the traditional device faces the cutting requirements of the complex shape of the substrate, and makes the device effectively improve the processing efficiency of cutting the substrate while ensuring the cutting quality.
[0030] Working principle: Before cutting the substrate, the operator needs to move the substrate to the center of the top surface of the cutting base plate 101 and then activate the first motor 102. Since a first synchronizing rod 107 is provided between the two first lead screws 106, and conical teeth are respectively provided on the outer wall of one end of the first lead screw 106 and the outer walls of both ends of the first synchronizing rod 107, the first lead screw 106 and the first synchronizing rod 107 rotate relative to each other through the meshing transmission between the conical teeth. By placing the first synchronizing rod 107 between the first lead screws 106, the output end of the first motor 102 can simultaneously drive multiple first lead screws 106 inside the first cutting bracket 1 to rotate simultaneously. Furthermore, the first cutting bracket 1 has synchronizing rods 107 on both sides inside. Multiple first slide rails 108 are provided, and the first slide rails 108 pass through the first limiting slide 105, so that the first slide rails 108 restrict the movement trajectory of the first limiting slide 105. As the first lead screw 106 rotates inside both sides of the first cutting bracket 1, the first lead screw 106 can cooperate with the first slide rail 108, and push the first limiting slide 105 horizontally along the outer wall of the first slide rail 108 through its own outer wall thread. Multiple second lead screws 203 inside the second cutting bracket 2 pass through one end of the second limiting slide 202, and multiple second slide rails 205 are fixed on both sides of the second cutting bracket 2. The second slide rails 205 and the second limiting slide 202 are connected by a thread. The end passes through and slides, thus limiting the movement trajectory of the second limiting slide 202. Since a second synchronizing rod 204 is provided between the second lead screws 203 and they mesh with each other through bevel gears, multiple second lead screws 203 on both sides of the inner side of the second cutting bracket 2 can simultaneously rotate on both sides of the inner side of the second cutting bracket 2 under the drive of the output end of the second motor 201. Furthermore, since both the second limiting slide 202 and the first limiting slide 105 can limit the limiting support 103 through their own inner walls, the first limiting slide 105 is arranged crosswise with the second limiting slide 202. As the first lead screw 106 and the second lead screw 203 respectively drive the first limiting slide 105 and the second limiting slide 202 through their own outer wall threads... The second limiting slide 202 moves in different directions along the outer walls of the first slide rail 108 and the second slide rail 205. Under the action of the inner walls of the first limiting slide 105 and the second limiting slide 202, it can drive the limiting support 103 at one end and the laser cutting head 104 to make various movements such as arcs and straight lines on the top of the cutting base plate 101, so as to complete the cutting work of the complex shape of the substrate in one go. Thus, through the mutual cooperation of the first lead screw 106, the second lead screw 203 and the first limiting slide 105 and the second limiting slide 202, the laser cutting head 104 can be driven to make various movement trajectories on the top of the substrate, such as arcs and straight lines, and complete the cutting work of the complex shape of the substrate in one go.
