Description

Technical Field

[0001] This invention relates to the field of power electronic component fixture technology, and specifically to a positioning and holding fixture for manufacturing power electronic components. Background Technology

[0002] Electronic components are the components of electronic parts and small 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, radio, and instruments. They are a general term for electronic devices such as capacitors, transistors, hairsprings, and clockwork. When dispensing electronic components, it is necessary to use positioning clamps to hold the electronic components.

[0003] Chinese Patent (application number: CN202220605807.8) discloses a positioning fixture for coating electronic components, including a positioning fixture body. The positioning fixture body includes a base, and an easy-to-install device is provided on the upper part of the base. A clamping and positioning mechanism is provided on the inner side of the easy-to-install device. The easy-to-install device includes a movable seat, a fixed plate, an elastic limiting tube, and an installation rod. The lower surface of the movable seat is fixedly connected to the upper surface of the base. The clamping and positioning mechanism includes a clamping plate and an elastic tension ball.

[0004] The patent and existing technologies have the following technical problems in practical use:

[0005] 1. This positioning fixture, unlike existing fixtures, usually places electronic components in a designated position and requires repeated manual clamping and adjustment to hold the electronic components. It cannot automatically achieve positioning and clamping according to different placement positions of electronic components. In addition, some positioning is achieved by sensors, which can only perform simple positioning and cannot automatically adjust the clamping range according to the size of the circuit board, making clamping inconvenient.

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0068] A preferred embodiment of the present invention, a positioning and clamping fixture for manufacturing power electronic components, will be described in detail below, such as... Figure 1 As shown, a positioning and clamping fixture for manufacturing power electronic components includes: a frame 1, a loading assembly 2, an automatic clamping assembly 3, a positioning assembly 4, and a control assembly 5. The loading assembly 2 is disposed on the top of the frame 1, two sets of automatic clamping assemblies 3 are disposed on the outside of the loading assembly 2, two sets of positioning assemblies 4 are disposed on the outside of the loading assembly 2, and two sets of control assemblies 5 are disposed on the outside of the loading assembly 2.

[0069] The circuit board is placed on the carrier component 2. The carrier component 2 automatically identifies the position of the circuit board. The control component 5 provides feedback and controls the positioning component 4 to operate. The positioning component 4 limits the rising height of the automatic clamping component 3 and then controls the automatic clamping component 3 to rise. Then, air is supplied to the automatic clamping component 3 and the carrier component 2, so that the circuit board can be automatically clamped. By controlling the voltage, the clamping height can be controlled.

[0070] Furthermore, such as Figures 2-4As shown, the loading assembly 2 includes: a loading platform 21, a loading plate 23, a top spring 22, air pressure holes 24, a telescopic top tube 25, a lifting cylinder 26, a lifting plate 27, a pneumatic rod 28, and sliding holes 29. The loading platform 21 is located on the top of the frame 1, and the loading plate 23 is linearly arranged on the top of the loading platform 21. A top spring 22 is arranged between the loading plate 23 and the loading platform 21. Air pressure holes 24 are linearly arrayed inside the loading platform 21. A telescopic top tube 25 is provided at the top, and the telescopic top tube 25 is located directly below the carrying plate 23. In the initial state, there is a gap between the telescopic top tube 25 and the carrying plate 23. A lifting cylinder 26 is installed inside the frame 1. A lifting plate 27 is installed at the telescopic end of the lifting cylinder 26. A pneumatic rod 28 is linearly arranged on the top of the lifting plate 27. The pneumatic rod 28 slides in the pneumatic hole 24. Sliding holes 29 are linearly opened on both sides of the top of the carrying platform 21.

[0071] The circuit board is placed on the carrier plate 23. Initially, there is a gap between the telescopic jacking tube 25 and the carrier plate 23. The telescopic jacking tube 25 does not affect the descent of the carrier plate 23. Since the carrier plate 23 is linearly designed, the circuit board drives the carrier plate 23 below it to descend, thereby providing feedback on the position of the circuit board. When clamping, the lifting cylinder 26 is controlled to operate. The lifting cylinder 26 drives the lifting plate 27 to rise. The lifting plate 27 drives the pneumatic rod 28 to rise. The pneumatic rod 28 forces the gas inside the pneumatic hole 24 into the telescopic jacking tube 25. The telescopic jacking tube 25 lifts the carrier plate 23, thereby adjusting the placement height of the circuit board.

[0072] Furthermore, such as Figure 5 , Figure 6 As shown, both sets of automatic clamping components 3 include: a clamping motor 31, a clamping screw 32, a pressure rod 33, a support plate 34, a clamping nut 35, a telescopic pressure tube 36, a support rod 38, and an elastic pull rope 39. The pressure rod 33 is slidably connected inside the sliding hole 29. The bottom of the pressure rod 33 is provided with a support plate 34. Multiple sets of pressure rods 33 are fixedly connected to a support plate 34. The outside of the support plate 34 is provided with a clamping nut 35. The clamping motor 31 is installed on the top of the platform 21. The output end of the clamping motor 31 is equipped with a clamping screw 32. The clamping screw 32 is threadedly connected to the clamping nut 35. The clamping end of the pressure rod 33 is provided with a telescopic pressure tube 36. The inside of the telescopic pressure tube 36 is provided with a support rod 38. An elastic pull rope 39 is provided between the support rod 38 and the pressure rod 33.

[0073] The two sets of automatic clamping components 3 also include: clamping air cylinder 312 and clamping piston rod 313. The clamping air cylinder 312 is linearly arranged on the top of the support plate 34. The clamping air cylinder 312 and the pressure rod 33 are distributed alternately. The clamping air cylinder 312 is connected to the pressure rod 33 through an air pipe. The clamping piston rod 313 is slidably connected to the inside of the clamping air cylinder 312. The top of the clamping piston rod 313 is fixedly connected to the bottom of the platform 21.

[0074] A threaded connector 37 is provided on the outside of the telescopic pressure tube 36, and a magnetic frame 310 is provided on the outside of the pressure rod 33. A sealing cover 311 is magnetically attracted to the outside of the magnetic frame 310, and the sealing cover 311 can be threadedly connected to the threaded connector 37.

[0075] The top of the pressure rod 33 is designed in a hook shape.

[0076] When clamping is required, the clamping motor 31 is powered on, which drives the clamping screw 32 to rotate. The clamping screw 32 drives the support plate 34 to rise through the clamping nut 35. The support plate 34 drives multiple sets of pressure rods 33 to rise. Since the top of the pressure rod 33 is hook-shaped and the telescopic pressure tube 36 is located at the hook end of the pressure rod 33, the higher the pressure rod 33 rises, the closer the bottom of the telescopic pressure tube 36 is to the middle of the platform 21 when it is fully extended. By controlling the lifting height of the pressure rod 33, the telescopic pressure tube 36 can press on different positions on the platform 21. At the same time, since the automatic clamping assembly 3 is provided with two sets, the pressure rods 33 on both sides are controlled to rise to different heights, thereby clamping the circuit board at any position on the platform 21.

[0077] As the support plate 34 drives multiple sets of pressure rods 33 to rise, the support plate 34 also drives the clamping air cylinder 312 to rise. The clamping air cylinder 312 rises relative to the clamping piston rod 313. The clamping piston rod 313 presses the air pressure in the clamping air cylinder 312 into the telescopic pressure tube 36, causing the telescopic pressure tube 36 to expand and extend. The higher the pressure rod 33 rises, the longer the clamping distance, and the longer the telescopic pressure tube 36 extends, resulting in stable clamping. When the support plate 34 descends, the telescopic pressure tube 36 can automatically return to its original position under the action of the elastic pull rope 39 and the support rod 38, making it convenient to use.

[0078] When cleaning of the carrier plate 23 is required, unscrew the sealing cap 311 from the threaded joint 37, and then let the sealing cap 311 adhere to the magnetic frame 310. At this time, the telescopic pressure tube 36 is ventilated and cannot extend. When the support plate 34 rises, the support plate 34 drives the clamping air cylinder 312 to rise. The clamping air cylinder 312 rises relative to the clamping piston rod 313. The clamping piston rod 313 blows the gas in the clamping air cylinder 312 out through the telescopic pressure tube 36. As the pressure rod 33 rises, the gas sprayed from the telescopic pressure tube 36 blows from the outermost carrier plate 23 to the middle carrier plate 23, thereby cleaning the carrier plate 23 thoroughly and achieving a good self-cleaning effect.

[0079] Furthermore, such as Figure 7 , Figure 8As shown, both sets of positioning components 4 include: a limiting plate 41, an insertion hole 42, a threaded hole 43, a limiting rod 44, a motor frame 45, a DC motor 46, a key shaft 47, and a limiting screw 48. The limiting plate 41 is provided on the outer side of the stage 21. The limiting plate 41 has an insertion hole 42 inside and a threaded hole 43 on the side. The limiting rod 44 is provided on the top of the support plate 34. The top of the limiting rod 44 is tapered. The motor frame 45 is provided on the outer side of the stage 21. The DC motor 46 is installed on the outer side of the motor frame 45. The key shaft 47 is installed at the output end of the DC motor 46. The limiting screw 48 is sleeved on the outer side of the key shaft 47. The limiting screw 48 has a keyway inside. The key on the key shaft 47 is inserted into the keyway. The limiting screw 48 is threaded into the threaded hole 43.

[0080] By controlling the DC motor 46 to rotate, the DC motor 46 drives the key shaft 47 to rotate, and the key shaft 47 drives the limit screw 48 to rotate. The limit screw 48 moves under the action of the threaded hole 43, thereby controlling the length of the limit screw 48 in the insertion hole 42. Since the top of the limit rod 44 is tapered, the lifting height of the limit rod 44 can be controlled. The limit rod 44 controls the lifting height of the pressure rod 33 through the support plate 34.

[0081] Both sets of control components 5 include: mounting plate 51, sliding rheostat 52, transmission air cylinder 53, control air cylinder 54, connecting pipe 55, piston rod 56, and tension spring 57. Mounting plate 51 is mounted on the outside of platform 21. Sliding rheostat 52 is mounted on the outside of mounting plate 51. Sliding rheostat 52 is connected in series with DC motor 46. Transmission air cylinder 53 is linearly mounted on the outside of platform 21. The number of transmission air cylinders 53 is half the number of platforms 23. Transmission air cylinder 53 is located directly below platform 23. Control air cylinder 54 is mounted on the outside of mounting plate 51. Connecting pipe 55 is provided on the outside of control air cylinder 54. Connecting pipe 55 is connected to transmission air cylinder 53. Piston rod 56 is slidably connected inside control air cylinder 54. Piston rod 56 is connected to the slider on sliding rheostat 52. Tension spring 57 is provided between piston rod 56 and control air cylinder 54.

[0082] The circuit board is placed on the carrier plate 23. Initially, there is a gap between the telescopic top tube 25 and the carrier plate 23. The telescopic top tube 25 does not affect the descent of the carrier plate 23. Since the carrier plate 23 is linearly designed, the circuit board drives the carrier plate 23 below it to descend. The carrier plate 23 compresses the transmission cylinder 53. The gas inside the transmission cylinder 53 is forced into the control cylinder 54 through the connecting pipe 55. The air pressure pushes the piston rod 56 to slide. The piston rod 56 drives the slider on the sliding rheostat 52, which in turn controls the voltage of the DC motor 46. Since the voltage of the DC motor 46 changes, the speed of the DC motor 46 changes per unit time, which in turn controls the length of the limit screw 48 in the insertion hole 42, and then limits the lifting height of the pressure rod 33.

[0083] When the circuit board is placed on the carrier plate 23 near the left, the number of carrier plates 23 pressed down on the left is greater than the number of carrier plates 23 pressed down on the right. Therefore, the sliding distance of the left piston rod 56 is longer than that of the right piston rod 56. The voltage of the left DC motor 46 is greater than that of the right DC motor 46 through the sliding rheostat 52. The length of the left limiting screw 48 in the socket 42 is greater than that of the right limiting screw 48 in the socket 42. When the support plate 34 rises, under the action of the limiting rod 44 and the limiting screw 48, the rising height of the left support plate 34 is less than that of the right support plate 34. The height of the left pressure rod 33 is lower than that of the right pressure rod 33. The clamping distance of the left telescopic pressure tube 36 is less than that of the right telescopic pressure tube 36. Thus, the circuit board position can be automatically identified and clamped, making clamping convenient.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
