Description

Technical Field

[0001] The invention relates to the technical field of power electronic component processing, in particular to a power electronic component drilling device. Background Art

[0002] Electronic components are components of electronic elements and small and medium-sized machines and instruments. They are usually composed of several parts and can be used in similar products. They often refer to certain parts in industries such as electrical appliances, radios, and instruments, such as capacitors, transistors, hairsprings, springs and other electronic devices. During the processing of electronic components, drilling devices are required to complete the processing and production of electronic components.

[0003] A Chinese patent discloses a drilling device for the production of electronic components with a clamping function (publication number: CN112091271A). The patent uses a screw drive assembly to drive two clamping ring plates to move closer or farther together, making it easier to clamp and fix the electronic components. The dust removal device can also remove dust from the two clamping ring plates during drilling and clamping through a dust removal pipe. However, when blind holes need to be drilled on multiple sides of the electronic components, the patent requires the electronic components to be removed and clamped again. This method requires more operational processes, thereby reducing processing efficiency. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0026] See also Figure 1-5 As shown, the present invention is a power electronic component drilling device, comprising a workbench 1, a lifting drill 2 is fixedly connected to the top of the workbench 1, a fixed seat 3 is fixedly connected to one side of the top of the workbench 1, an electric telescopic rod 4 is fixedly connected to the inside of the fixed seat 3, an output end of the electric telescopic rod 4 is fixedly connected to a movable seat 5 for placing electronic components, a limiting frame 6 for limiting the position of the electronic components is provided inside the movable seat 5, a hollow groove 7 is provided on the end surface of the limiting frame 6, and a fixed screwdriver 3 is fixedly connected to the top of the workbench 1 and located on one side of the movable seat 5. A fixing frame 8, one side of the fixing frame 8 is fixedly connected to a servo motor 9, the output end of the servo motor 9 passes through the fixing frame 8 and is fixedly connected to a limit plate 10, and a plurality of plug rods 11 adapted to the inner wall of the hollow groove 7 are fixedly connected to the limit plate 10, and the limit plate 10 and the limit frame 6 are used to elastically clamp the electronic components. Compared with the prior art, by directly clamping the electronic components, it is difficult to control the force required for clamping and the distance the clamping parts move, so it is very likely to cause damage to the surface of the electronic components.

[0027] In order to realize the elastic clamping of electronic components, a connecting rod 12 is fixedly connected to one side of the limit frame 6, a connecting sleeve 14 is provided on one side of the inner wall of the movable seat 5, a rotating groove 15 adapted to the surface of the connecting rod 12 is provided on one side of the connecting sleeve 14, and a compression spring 17 is provided on the outer surface of the connecting rod 12, one end of the compression spring 17 is fixedly connected to one side of the connecting sleeve 14, and the compression spring 17 can give a thrust to the limit frame 6 when squeezed, so as to clamp the electronic components, and a plurality of limit blocks 13 are fixedly connected to the surface of the connecting rod 12. A plurality of blocking blocks 16 are fixedly connected to the inner surface of the movable groove 15, and one side of the blocking block 16 is slidably connected to one side of the limit block 13. When the limit block 13 is located between two adjacent blocking blocks 16, it can limit the connecting rod 12 to prevent the limit frame 6 on the connecting rod 12 from rotating at will. When the limit block 13 completely passes through the two blocking blocks 16, the connecting rod 12 can rotate at this time. Both sides of the top of the workbench 1 are fixedly connected with slide rails 22, and the top of the slide rails 22 is slidably connected with a slider 23, and the top of the slider 23 is fixedly connected to the bottom of the moving seat 5.

[0028] In order to prevent the electronic components from being unable to rotate due to the contact between the moving seat 5 and the bottom of the electronic components when they are rotated, the bottom of the moving seat 5 is fixedly connected to a fixed sleeve 18, and the inner surface of the fixed sleeve 18 is slidably connected to a sliding rod 19. The top of the sliding rod 19 is fixedly connected to a support plate 21, and a support spring 20 is provided on the outer surface of the sliding rod 19 and below the support plate 21. When the electronic components are placed on the support plate 21, since the support plate 21 can slide downward, when the electronic components rotate with the limit frame 6, no hard contact will occur, causing them to be unable to rotate or causing damage to the electronic components.

[0029] In order to enable the coolant to be reused, the workbench 1 is fixedly connected with a guide frame 28 that follows the lifting drill rig 2 for lifting, and a water spray pipe 29 for adjusting the angle is fixedly connected to the guide frame 28. A reflux slot is opened through the top of the workbench 1, and a collection box 24 for storing coolant is fixedly connected to the top of the workbench 1 and below the reflux slot. A reflux pipe 25 is set through one side of the collection box 24, and a water pump 26 is fixedly connected to the top of the workbench 1. The water inlet end of the water pump 26 is connected to one end of the reflux pipe 25, and the water outlet end of the water pump 26 is connected to a hose 27, and one end of the hose 27 is connected to one end of the water spray pipe 29. The interior of the collection box 24 is fixedly connected with a support frame 30, and the surface of the support frame 30 is provided with a filter cotton sleeve 31 for filtering impurities. The inner surface of the collection box 24 is fixedly connected with an annular conical plate 32. The conical plate 32 can concentrate the coolant into the interior of the filter cotton sleeve 31, and the top of the filter cotton sleeve 31 is fixedly connected with a handle 33.

[0030] The working principle of the present invention is as follows: first, the electronic components that need to be drilled are placed above the support plate 21, and the electric telescopic rod 4 in the fixed seat 3 is started to extend, so that the slider 23 on the movable seat 5 slides on the surface of the slide rail 22 toward the side close to the servo motor 9, and further the insertion rod 11 on the limit plate 10 is inserted into the inside of the hollow groove 7. At this time, the limit frame 6 and the side opposite to the limit plate 10 limit the electronic components, and under the continuous push of the electric telescopic rod 4, the compression spring 17 on the connecting rod 12 is compressed, and the connecting rod 12 slides toward the inside of the rotating groove 15, thereby clamping the electronic components to prevent the electronic components from being damaged. At this time, the electronic components can be drilled by the drill bit on the lifting drill rig 2. When it is necessary to drill other surfaces of the electronic components, the electric telescopic rod 4 is extended to make the limit block 13 on the connecting rod 12 staggered with the rotating groove 15, and then the servo motor 9 on the fixed frame 8 is started to rotate, thereby driving the limit The positioning plate 10 rotates, and due to the connection between the insertion rod 11 and the hollow groove 7, the limiting block 13 is driven to rotate on the inner surface of the rotating groove 15, and the limiting frame 6 is further driven to rotate. At this time, the electronic component pushes the sliding rod 19 on the support plate 21 to slide inside the fixed sleeve 18 when rotating, so that the surface of the electronic component that needs to be drilled is rotated upward. At this time, the drilling rig 2 can be lifted and lowered to drill again, and when drilling, the water pump 26 is started to pump the water through the return pipe 25. The coolant in the collection box 24 is pumped into the inside of the hose 27 and sprayed on the drill hole through the water spray pipe 29 to cool it down and take away the dust generated during drilling. The coolant remains on the conical plate 32 through the reflux groove and falls into the inside of the support frame 30. When the coolant is reused, the filter cotton sleeve 31 can block the dust. When the filter cotton sleeve 31 needs to be removed, the filter cotton sleeve 31 can be pulled out from the inside of the support frame 30 through the handle 33 to clean the filter cotton sleeve 31.

[0031] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
