Description

Technical Field

[0001] This utility model relates to the field of semiconductor processing equipment, and more specifically, to a precision cutting device for metal parts. Background Technology

[0002] Metal parts require cutting during processing. For example, semiconductors are materials whose conductivity at room temperature falls between that of conductors and insulators. Semiconductors have wide applications in radios, televisions, and temperature measurement. Diodes, for instance, are devices made using semiconductors. Semiconductors are materials whose conductivity can be controlled, ranging from that of insulators to conductors. After manufacturing, semiconductors need to be cut to appropriate sizes for subsequent processing.

[0003] Patent application number 202122103016.3 discloses a semiconductor cutting device, including a cutting platform. A laser cutting device is mounted on the top of the cutting platform, and a support frame is fixedly connected to the bottom of the platform. A waste collection box is placed on the inner wall of the bottom of the support frame. A feeding port is opened on the top of the cutting platform, and grooves are formed on both inner walls of the feeding port. A slider is slidably mounted on the inner wall of each groove. A vibration spring is fixedly connected between the slider and the groove. A feeding screen is positioned between the two sliders, and a fixed disk is fixedly connected to the bottom of the feeding screen. A rotating motor is fixedly connected to the inner wall of the bottom of the waste collection box, and a rotating shaft is fixedly connected to the output shaft of the rotating motor. A rotating disk is fixedly connected to the top of the rotating shaft. This invention has the advantage of preventing the feeding screen from clogging.

[0004] Regarding the aforementioned related technologies, a rotating motor drives a rotating disk to rotate, which in turn causes hemispherical vibrating blocks on the rotating disk to continuously press against vibrating blocks on a fixed disk. Under the action of a slider and a chute, the feeding screen can move up and down. Under the elastic force of the vibration spring, combined with the pressing of the vibrating blocks, the feeding screen vibrates continuously up and down, thereby preventing the feeding screen from clogging. However, in this application, the feeding screen does not have a fixed structure. When the equipment cuts semiconductors, the semiconductors may move due to the vibration of the feeding screen, reducing the cutting quality of the semiconductors. Utility Model Content

[0005] To solve the above problems, this utility model provides a precision cutting device for metal parts, which adopts the following technical solution:

[0006] A precision cutting device for metal parts includes a base frame, a bracket fixedly installed at the bottom end of the base frame, a limit frame fixedly installed at the top end of the base frame, a support frame fixedly installed at the top end of the limit frame, a filter plate provided inside the base frame, a clamping assembly provided at the top of the filter plate, a first linear motor module fixedly installed on the inner wall of the top end of the support frame, a second linear motor module provided at the bottom of the first linear motor module, a first telescopic rod provided at the bottom of the second linear motor module, and a laser cutting assembly provided at the end of the first telescopic rod.

[0007] A collection frame is provided inside the bottom frame. The collection frame slides through the bottom frame on one side. A filter cloth and filter cotton are provided inside the bottom frame. The filter cotton is located below the filter cloth. A dust extraction component is provided below the collection frame, and a cleaning component is provided above the filter cloth.

[0008] By adopting the above technical solution, when using this equipment, the operator places the semiconductor above the filter plate and then clamps and fixes the semiconductor using the clamping assembly, which helps maintain the stability of the semiconductor during cutting. After the semiconductor is clamped, the first telescopic rod drives the laser cutting assembly to cut the semiconductor. The cooperation of the first linear motor module and the second linear motor module changes the longitudinal and lateral positions of the laser cutting assembly, making it easier for the equipment to cut the semiconductor in different directions. When the laser cutting assembly cuts the semiconductor, it may generate smoke and debris. The dust extraction assembly generates air suction, which allows the smoke and debris to pass through the filter plate into the collection frame. The collection frame is equipped with filter cloth and filter cotton, which can filter the debris and help prevent the debris from entering the dust extraction assembly, thus maintaining the operating effect of the dust extraction assembly. In addition, a cleaning assembly is provided on the top of the filter cloth to clean the debris on the top of the filter cloth, making it easier for the debris to accumulate on both sides of the filter cloth. This helps to prevent the top of the filter cloth from being affected by excessive debris accumulation, thus maintaining the dust extraction effect of the equipment.

[0009] Furthermore, the clamping assembly includes two clamping plates that slide on top of the filter plate. Rubber pads are fixedly installed on the opposite side of the two clamping plates. Cylinders are fixedly installed on both sides of the limiting frame. The piston shafts of the two cylinders slide through the limiting frame and are fixedly connected to the opposite side of the clamping plate on the same side.

[0010] By adopting the above technical solution, the operator places the semiconductor above the filter plate, and then drives the clamping plates to move by the cylinder, so that the two clamping plates contact the opposite side of the semiconductor, which can play the role of clamping and fixing the semiconductor, which helps to maintain the stability of semiconductor cutting and thus helps to maintain the cutting quality of semiconductor.

[0011] Furthermore, the dust extraction assembly includes an air collection hopper disposed within the bottom frame, the air collection hopper being located below the collection frame, an installation plate being fixedly installed on one side of the bottom frame, an exhaust fan being provided at the bottom of the installation plate, and a connecting pipe being connected to the bottom of the air collection hopper opposite to the exhaust fan.

[0012] By adopting the above technical solution, the suction generated by the exhaust fan draws the smoke and waste generated during the cutting process into the collection frame through the filter plate, thus collecting the waste. The collection frame is equipped with filter cloth and filter cotton to filter the waste debris, which helps to prevent the waste debris from entering the exhaust fan and helps to maintain the performance of the exhaust fan.

[0013] Furthermore, the cleaning assembly includes a brush plate slidably mounted on top of the filter cloth, a second telescopic rod fixedly mounted on one side of the collection frame, the end of the second telescopic rod being fixedly connected to the side opposite to the brush plate, a battery being provided on one side of the collection frame, a baffle being provided above the battery, and two symmetrically distributed sliding rods being fixedly mounted inside the collection frame, with the ends of the two sliding rods away from the battery sliding through the brush plate.

[0014] By adopting the above technical solution, the brush plate is driven to move back and forth on the top of the filter cloth by the second telescopic rod, which plays the role of cleaning the filter cloth. This facilitates the accumulation of waste on both sides of the filter cloth, helps to prevent the top of the filter cloth from being affected by excessive waste accumulation, thus maintaining the dust collection effect of the equipment.

[0015] Furthermore, sliders are fixedly installed on both sides of the collection frame, and the inner wall of the bottom frame is provided with a groove that matches the slider on the same side. The side walls of the sliders are all fitted with rubber sleeves.

[0016] By adopting the above technical solution, workers can pull the collection frame by hand to move it out of the bottom frame, which facilitates the subsequent cleaning of waste. The collection frame is equipped with sliders on both sides, which engage with the grooves opened on the inner wall of the bottom frame to support and stabilize the collection frame. The sliders are also fitted with rubber sleeves on their side walls, which helps to increase the friction between the sliders and the grooves on the same side, thereby helping to maintain the stability of the collection frame placed inside the bottom frame.

[0017] Furthermore, the bottom of the support frame is provided with an insert block, and the top of the limiting frame is provided with a slot that matches the insert block.

[0018] By adopting the above technical solution, when installing the support frame, the workers place the support frame above the limiting frame, so that the plug installed at the bottom of the support frame engages with the slot opened at the top of the limiting frame, which plays the role of positioning the support frame and facilitating subsequent fixing.

[0019] Furthermore, two symmetrically distributed locking blocks are fixedly installed on both sides of the filter plate, and the inner walls of the limiting frame and the bottom frame are provided with locking grooves that match the locking blocks on the same side.

[0020] By adopting the above technical solution, the filter plate has a locking block on its side wall. The locking block engages with the slot opened on the inner wall of the bottom frame, which can be used to position and install the filter plate, and facilitates the subsequent disassembly and cleaning of the filter plate.

[0021] In summary, this utility model has the following beneficial technical effects:

[0022] (1) In this utility model, by setting up the clamping component, the clamping plate is moved by the cylinder so that the two clamping plates come into contact with the opposite side of the semiconductor, which can play the role of clamping and fixing the semiconductor, which is beneficial to maintaining the stability of semiconductor cutting and thus to maintaining the cutting quality of the semiconductor.

[0023] (2) In this utility model, by setting up the dust extraction component, the suction force generated by the exhaust fan will draw the smoke and waste generated during the cutting of the equipment into the collection frame through the filter plate, which can play the role of collecting waste. The collection frame is equipped with filter cloth and filter cotton to achieve the effect of filtering waste, which helps to prevent waste from entering the exhaust fan and helps to maintain the performance of the exhaust fan.

[0024] (3) In this utility model, a cleaning component is provided on the top of the filter cloth. The brush plate is driven to move back and forth on the top of the filter cloth by the second telescopic rod, which plays the role of cleaning the filter cloth. This makes it easier for waste to accumulate on both sides of the filter cloth, which helps to prevent the top of the filter cloth from being affected by too much waste and thus affecting the airflow. This helps to maintain the dust collection effect of the equipment. Attached Figure Description

The collection frame 14 is provided with a filter cloth 20 and a filter cotton 21, which achieves the effect of filtering waste and helps to prevent waste from entering the exhaust fan 10, thus maintaining the performance of the exhaust fan 10.

[0037] A cleaning assembly is provided above the filter cloth 20. The cleaning assembly includes a brush plate 13 that is slidably installed above the filter cloth 20. A second telescopic rod 18 is fixedly installed on one side of the collection frame 14. The end of the second telescopic rod 18 is fixedly connected to the side opposite to the brush plate 13.

[0038] The collection frame 14 is fixedly installed with sliders 15 on both sides. The inner wall of the bottom frame 1 is provided with a groove that matches the slider 15 on the same side.

[0041] The implementation principle of this utility model embodiment is as follows: When using the device, the operator places the semiconductor above the filter plate 17, and then clamps and fixes the semiconductor using the clamping assembly, which helps to maintain the stability of the semiconductor during cutting. After the semiconductor is clamped, the first telescopic rod 6 drives the laser cutting assembly 7 to cut the semiconductor. The cooperation of the first linear motor module 4 and the second linear motor module 5 changes the longitudinal and lateral positions of the laser cutting assembly 7, making it easier for the device to cut the semiconductor in different directions. When the laser cutting assembly 7 cuts the semiconductor, it may generate smoke and debris. The dust extraction assembly generates air suction, which allows the smoke and debris to pass through the filter plate 17 into the collection frame 14. The collection frame 14 is equipped with a filter cloth 20 and a filter cotton 21, which can filter the debris and help prevent the debris from entering the dust extraction assembly, thus maintaining the operating effect of the dust extraction assembly.
