[0005] To address the shortcomings of existing technologies, this invention provides a laser cutting device for connector housings with clamp-type fixing, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting device for a clamp-type fixed connector housing, comprising a cutting positioning component, a laser cutting head fixedly connected to the top of the cutting positioning component, a support platform fixedly connected to the bottom of the cutting positioning component, a suction mechanism fixedly connected to the bottom of the support platform, the suction mechanism comprising a follower positioning component, a suction box fixedly connected to the top of the follower positioning component at the bottom of the support platform, an air extraction component fixedly connected to the back of the suction box, and a pushing mechanism provided on the top of the suction mechanism, the pushing mechanism comprising an impact component and a buffer component, the impact component being disposed inside the suction box.

[0007] Preferably, the air extraction assembly includes an air extraction pipe, which is fixedly connected to the back of the suction box, and an air extraction fan is fixedly connected inside the air extraction pipe.

[0008] Preferably, an isolation net is fixedly connected to the back of the suction box at the position corresponding to the suction pipe, a scraper is fixedly connected to the bottom of the buffer assembly at the front of the isolation net, and an openable door is provided on the front of the suction box.

[0009] Preferably, the top of the suction box is fixedly connected to a top cover, and the support platform supporting the workpiece to be cut has a mesh structure and a rough surface.

[0010] Preferably, the impact assembly includes a partition plate, which is fixedly connected inside the suction box. A guide post is movably connected inside the partition plate, and a mounting platform is fixedly connected to the top of the guide post. A laser plate is fixedly connected to the top of the mounting platform.

[0011] Preferably, the bottom of the mounting platform is movably connected to a roller, the bottom of the mounting platform is fixedly connected to a first spring, and the bottom of the first spring is fixedly connected to a partition plate. A shielding frame is provided on the top of the partition plate, and the shielding frames are all located at the bottom of the corresponding rollers. An air inlet that cooperates with the bottom of the shielding frame is provided on the top of the partition plate.

[0012] Preferably, a side post is fixedly connected to the side of the shielding frame near the inner wall of the corresponding suction box, and the side post is movably connected to the suction box. A second spring is fixedly connected to the side of the shielding frame near the inner wall of the corresponding suction box, and the second spring is fixedly connected to the inner wall of the suction box.

A third spring is fixedly connected to the bottom of the fixing tube, and a buffer tube is fixedly connected to the bottom of the third spring and fixedly connected to the outer wall of the fixing tube.

[0014] This invention provides a laser cutting device for a clamp-type fixed connector housing. It has the following advantages:

[0015] 1. This clamp-type fixed connector housing laser cutting device generates air intake through the central opening of the top cover. Combined with the mesh structure of the support platform, it makes the connector fit tightly against the top of the support platform, realizing the rapid fixing of connector housings of various specifications and preventing the connector housing from sliding during cutting, which can significantly improve the cutting efficiency of connectors.

[0016] 2. This clamp-type fixed connector housing laser cutting device draws in splashed metal particles through the airflow into the suction box. These particles are then intercepted by an isolation net and continuously cut inside. The collected metal particles can be processed by opening the door on the front of the suction box, greatly saving the steps required to handle the splashed metal particles and indirectly improving the cutting efficiency.

[0017] 3. In this clamp-type fixed connector shell laser cutting device, after the cutting is completed, the mounting table impacts the bottom of the support table under the push of the first spring, and is transmitted through the support table, so that the cut connector shell is affected and lifted upward, which facilitates the quick removal of metal particles attached to the connector shell, reduces post-processing steps, and helps to improve cutting efficiency.

[0018] 4. The laser cutting device for the connector housing with clamp-type fixing causes the mounting table to impact the bottom of the support table, which in turn loosens the metal particles attached to the surface due to welding. This prevents excessive metal particles from adhering to the surface of the support table during continuous operation, reduces the amount of cleaning work during continuous processing, and indirectly improves the cutting efficiency.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0030] Example 1: Please refer to Figure 1-6 The present invention provides a technical solution: a laser cutting device for a clamp-type fixed connector shell, including a cutting positioning component 1, a laser cutting head 5 fixedly connected to the top of the cutting positioning component 1, a support platform 2 fixedly connected to the bottom of the cutting positioning component 1, a suction mechanism 3 fixedly connected to the bottom of the support platform 2, the suction mechanism 3 including a follow-up positioning component 31, a suction box 32 fixedly connected to the top of the follow-up positioning component 31 at the bottom of the support platform 2, an air extraction component 34 fixedly connected to the back of the suction box 32, and a pushing and impacting mechanism 4 provided on the top of the suction mechanism 3, the pushing and impacting mechanism 4 including an impact component 41 and a buffer component 42, the impact component 41 being disposed inside the suction box 32.

[0031] The connector housing to be cut is placed on top of the support platform 2. The position of the laser cutting head 5 is moved by the cutting positioning component 1. The laser is emitted from the bottom of the laser cutting head 5 to cut the connector housing. At the same time, during the cutting process, the suction box 32 is driven to the bottom by the follow-up positioning component 31, and the position of the suction box 32 is controlled by the follow-up positioning component 31 so that the suction box 32 is located at the bottom of the laser cutting head 5. The air inside the suction box 32 is discharged by the air extraction component 34, creating a negative pressure inside the suction box 32. When the suction box 32 is located at the bottom of the connector to be cut, a pressure difference is created between the bottom and top of the suction box 32. The air pressure at the top of the connector to be cut will push the connector to be cut downward. When the laser cutting head 5 emits laser to make a moving cut on the connector housing, the follow-up positioning component 31 makes the suction box 32 move together with the laser cutting head 5.

[0032] The air extraction assembly 34 includes an air extraction pipe 341, which is fixedly connected to the back of the suction box 32. An air extraction fan 342 is fixedly connected inside the air extraction pipe 341.

[0033] When the laser cutting head 5 emits a laser from its bottom to cut the connector housing, the exhaust fan 342 uses the exhaust pipe 341 to expel the air from the suction box 32, creating a negative pressure inside the suction box 32. This creates an airflow at the top of the suction box 32, which quickly flows over the laser cutting surface, rapidly cooling and solidifying the cut surface.

[0034] An isolation net 343 is fixedly connected to the back of the suction box 32 at the corresponding position of the suction pipe 341. A scraper 344 is fixedly connected to the bottom of the buffer assembly 42 at the front of the isolation net 343. An openable door is provided on the front of the suction box 32. When the suction assembly 34 starts to extract air from the inside of the suction box 32, the suction assembly 34 will move downward under the action of the impact assembly 41, so that the scraper 344 scrapes the surface of the isolation net 343, pushing the metal particles attached to the surface of the isolation net 343 downward, so as to avoid the continuous adhesion of metal particles to the surface of the isolation net 343 and affect the smoothness of airflow.

[0035] When the laser cutting head 5 emits a laser from its bottom to cut the connector housing, the sputtered metal particles are sucked into the suction box 32 by the flowing air. The metal particles sucked into the suction box 32 are intercepted by the isolation net 343 and left inside the suction box 32. When too many metal particles accumulate inside the suction box 32 due to continuous cutting, the metal particles collected inside the suction box 32 can be processed by opening the door on the front of the suction box 32.

[0036] The top of the suction box 32 is fixedly connected to the top cover 33. The support platform 2 supports the workpiece to be cut with a mesh structure and a rough surface.

[0037] When the air is drawn out of the suction box 32 by the suction component 34, air will be drawn in at the center opening of the top cover 33. Since the support platform 2 is a mesh structure, a negative pressure will be generated at the bottom of the connector shell to be cut under the restriction of the support platform 2. As a result, the connector shell to be cut will be pressed tightly against the top of the support platform 2 under the action of the air pressure at the top. And through the restriction of the rough surface of the top of the support platform 2, it is possible to quickly fix the connector shells of various specifications, and avoid the connector shells from sliding during cutting, which would cause the pre-cutting path to deviate and affect the cutting quality.

[0038] Example 2: Please refer to Figure 1-8 Based on Embodiment 1, the present invention provides a technical solution:

[0039] The impact assembly 41 includes a partition plate 419, which is fixedly connected inside the suction box 32. A guide post 412 is movably connected inside the partition plate 419. A limiting structure is provided between the guide post 412 and the partition plate 419, so that the guide post 412 can only move up and down relative to the partition plate 419. A mounting platform 411 is fixedly connected to the top of the guide post 412. A laser plate 413 is fixedly connected to the top of the mounting platform 411. The laser plate 413 can absorb the residual laser that penetrates the plate and suppress the upward reflection of the laser. The connection between the laser plate 413 and the mounting platform 411 is detachable, which facilitates the replacement of the laser plate 413 in the future.

[0040] The laser cutter head 5 cuts the connector housing from the bottom. The laser will irradiate the bottom of the laser plate 413. When the laser cutting head 5 is driven by the cutting positioning component 1 to cut, the follow-up positioning component 31 synchronously drives the suction box 32 to move, and puts the laser plate 413 at the bottom of the laser cutting head 5, so that the cutting laser always irradiates the top of the laser plate 413.

[0041] The bottom of the laser plate 413 is connected to the scraper 344. When the guide post 412 moves down, it can drive the scraper 344 to move downward, so that the scraper 344 scrapes the surface of the isolation net 343.

[0042] The bottom of the mounting platform 411 is movably connected to a roller 415, and the bottom of the mounting platform 411 is fixedly connected to a first spring 414, and the bottom of the first spring 414 is fixedly connected to a partition plate 419. A shielding frame 416 is provided on the top of the partition plate 419, and the shielding frames 416 are all located at the bottom of the corresponding roller 415. An air inlet that cooperates with the bottom of the shielding frame 416 is provided on the top of the partition plate 419.

[0043] A side post 417 is fixedly connected to the side of the shielding frame 416 near the inner wall of the corresponding suction box 32, and the side post 417 is movably connected to the suction box 32. A second spring 418 is fixedly connected to the side of the shielding frame 416 near the inner wall of the corresponding suction box 32, and the second spring 418 is fixedly connected to the inner wall of the suction box 32.

[0044] When the air is extracted from the suction box 32 by the suction assembly 34, the bottom of the partition plate 419 will be in a low-pressure state. The external air pressure will gradually push the mounting platform 411 downward and compress the guide column 412. As the mounting platform 411 moves downward, the mounting platform 411 will push the corresponding bottom shield 416 to the opposite side through the bottom roller 415, and compress the corresponding second spring 418, so that the air inlet on the partition plate 419 is opened, and air is sucked in from the top of the suction box 32.

[0045] After the cutting is completed, the air extraction assembly 34 stops expelling the air from the suction box 32. At this time, the mounting platform 411 will be pushed upward and reset under the push of the first spring 414. Under the push of the elastic force of the first spring 414, the laser plate 413 will hit the bottom of the support platform 2 and be transmitted through the support platform 2. This will affect the cut connector shell and push it upward, causing the connector shell to be impacted and promoting the removal of the metal particles adhering to its surface. In addition, the impact on the support platform 2 will also loosen the metal particles adhering to its surface due to welding. As a result, the support platform 2 will vibrate after each round of cutting, which will prevent the support platform 2 from having too many metal particles adhering to its surface during continuous operation and reduce the amount of cleaning work during continuous processing.

[0046] The buffer assembly 42 includes a fixed tube 421, which is fixedly connected to the bottom of the cutting positioning assembly 1 and located at the bottom of the laser cutting head 5. A third spring 423 is fixedly connected to the bottom of the fixed tube 421, and a buffer tube 422 is fixedly connected to the bottom of the third spring 423. The buffer tube 422 is fixedly connected to the outer wall of the fixed tube 421.

[0047] When the connector housing is pushed on top of the support platform 2, if the upward momentum of the connector housing is too large, the upward-moving connector housing will push the buffer tube 422 upward and compress the third spring 423 to buffer the impact and prevent the connector housing from hitting the bottom of the laser cutting head 5 under the influence of the top, causing damage to the laser cutting head 5.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
