Description

Technical Field

[0001] This utility model relates to the field of component processing technology, and in particular to inductor pin welding equipment. Background Technology

[0002] In the field of electronics manufacturing, PCBs (Printed Circuit Boards) are the basic components of various electronic devices. Numerous electronic components need to be soldered onto them to achieve specific circuit functions. Inductors, as one of the most common electronic components, are widely used in various circuits for storing and releasing electrical energy, filtering, and suppressing electromagnetic interference. A key step in soldering inductors onto the PCB is to accurately pass the inductor leads through the pre-set holes on the PCB and then solder the leads to ensure a stable and reliable electrical connection between the inductor and the PCB. This process is crucial for ensuring the performance and quality of electronic products. Poor soldering of the leads may lead to unstable circuit contact, obstructed signal transmission, and other problems, thereby affecting the normal operation of the entire electronic device.

[0003] Research has revealed that existing inductor pin soldering techniques typically employ a traditional method. This involves placing the circuit board within a frame, which serves to fix and support the board, preventing movement or wobbling during subsequent operations. After placement, a cover is placed, connected and secured to the frame using a specific fixing device, such as a latch. Then, a motor drives the entire device to flip, aligning the frame with the board facing upwards for subsequent soldering operations. For example, a soldering device for inductor pins disclosed in patent number CN220612592U uses this design. However, this existing technology suffers from a significant problem in practical applications: achieving an ideal horizontal position during the flipping process is difficult. In actual production, due to factors such as the precision of the motor drive, manufacturing errors in the mechanical structure, and gaps between transmission components, the frame often fails to achieve a precisely horizontal position after a 180-degree flip. This non-horizontal state negatively impacts subsequent soldering operations, and the latch-based stability after flipping may be insufficient.

[0004] Therefore, the applicant proposed an inductor pin soldering device as a solution. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Depend on Figures 1-7 The present invention includes a device base 1, with two frame plates 11 mounted on the top of the device base 1. A placement frame 12 is rotatably mounted inside the frame plates 11, and a cover 13 is hinged to one end of the placement frame 12. A flipping assembly 2 is mounted on a horizontal plate 14 fixed to the side wall of the frame plates 11. The flipping assembly 2 includes a hollow box 20 fixed to the top of the horizontal plate 14. A gear 21 is rotatably mounted on the inner wall of the hollow box 20. The gear 21 engages with the rotating shaft of the placement frame 12 and meshes with a toothed plate 22. The toothed plate 22 slides up and down in a slide rail 23 inside the hollow box 20. A cylinder 24 is fixed to the upper end of one side of the toothed plate 22. The cylinder 24 slides in a groove 26 of a moving plate 25. The moving plate 25 is horizontally mounted inside the hollow box 20. An electric drive assembly 3 is mounted on the top of the device base 1 to drive the moving plate 25 to move back and forth inside the hollow box 20. A plug-in assembly 4 is installed inside the hollow box 20 to limit the position of the placement frame 12.

[0029] The movable plate 25 and the crossbar 27 fixedly installed inside the hollow box 20 are slidably interlocked. The screw 28 is rotatably installed inside the hollow box 20 and is threadedly connected to the movable plate 25.

[0030] The electric drive assembly 3 includes a motor 31 fixed to the top of the equipment base 1. A composite toothed pulley 32 is installed at the output end of the motor 31. The composite toothed pulley 32 is connected to a secondary toothed pulley 34 via a toothed belt 33. The secondary toothed pulley 34 is rotatably mounted on the side wall of the hollow box 20 and is connected to the rotating shaft of the screw 28.

[0031] With the above structural design, in the initial state, the cover 13 is facing upwards and open. The PCB board with the inductor pins to be soldered is placed in the placement frame 12, and the cover 13, which is hinged to one end of the placement frame, is closed. A locking mechanism is used for initial fixation, completing the placement of the workpiece to be soldered. Then, when a flipping operation is required, the motor 31 fixed to the top of the equipment base 1 is started. A composite toothed pulley 32 is installed at the output end of the motor 31. The motor 31 drives the composite toothed pulley 32 to rotate. The rotation of the composite toothed pulley 32 is transmitted to the auxiliary toothed pulley 34 through the toothed belt 33, causing the auxiliary toothed pulley 34 to rotate around its own axis. This causes the screw 28 to rotate, and the moving plate 25 moves by the constraint of the crossbar 27. See details at this point. Figure 6The cylinder 24 is initially positioned at the horizontal end c of the channel 26, and then moves to the inclined section b. During this process, the position of the cylinder 24 within the channel 26 changes, causing the toothed plate 22 to slide upwards in the slide rail 23 inside the hollow box 20. This causes the gear 21 to rotate, which in turn causes the placement frame 12 to rotate 180 degrees. At this point, the cylinder 24 moves to the horizontal end a of the channel 26. After that, the motor 31 continues to operate, but the gear 21 and the placement frame 12 will not continue to operate. This effectively eliminates the error caused by the direct operation of the motor 31.

[0032] The plug-in assembly 4 includes a first inclined block 41 fixed to the bottom of the movable plate 25 and an air cylinder A46 fixed to the bottom of the hollow box 20. A piston lifting rod 47 is installed on the top of the air cylinder A46, and a second inclined block 42 is installed on the top of the piston lifting rod 47. The inclined surface of the second inclined block 42 corresponds to the inclined surface of the first inclined block 41. An air pipe 48 is connected to one side of the air cylinder A46, and an air cylinder B49 is connected to the air pipe 48. The air cylinder B49 is fixedly inserted through one side of the hollow box 20. A piston insertion rod 410 is installed at one end of the air cylinder B49. The piston insertion rod 410 can be inserted into the insertion hole of the cover 13 by horizontal movement.

[0033] Furthermore, when cylinder 24 has just moved to the horizontal end a of channel 26, the inclined surface of inclined block 22 42 is in contact with the inclined surface of inclined block 1 41. At this time, as motor 31 continues to operate, moving plate 25 continues to move horizontally. Due to the mutual compression of the inclined surfaces of inclined block 2 42 and inclined block 1 41, inclined block 2 42 generates a downward displacement in the vertical direction. The bottom of inclined block 2 42 is fixedly connected to piston lifting rod 47, which is inserted into air cylinder A46. When inclined block 2 42 moves downward, it drives piston lifting rod 47 to move downward together, compressing the air in air cylinder A46. One side of air cylinder A46 is connected to air cylinder B49 through air pipe 48. The compressed air in air cylinder A46 quickly enters air cylinder B49 through air pipe 48. As the air pressure in air cylinder B49 increases, the piston pushes piston rod 410 to move horizontally under the action of air pressure. The piston rod 410 is precisely inserted into the pre-set insertion hole on the cover 13, thereby limiting the position of the cover 13. During the process of limiting the cover 13, since the cover 13 is hinged to the placement frame 12, the fixed position of the cover 13 indirectly further fixes the position of the placement frame 12. At this time, the placement frame 12 is in a stable state after being flipped, and will not rotate downwards due to the loosening of the latch, providing reliable support for the subsequent soldering of the inductor pins (during this process, the cylinder 24 continues to move in the horizontal end a, without affecting the position of the placement frame 12). After that, the inductor pins can be inserted into the corresponding soldering holes on the PCB board inside the precisely positioned and stable placement frame 12, and soldered manually or by installing an existing electric soldering structure on the device base 1. This will not be described in detail here.

[0034] When the piston rod 410 moves horizontally and is inserted into the socket of the cover 13, the placement frame 12 is facing upwards, while the cover 13 is facing downwards.

[0035] Two lifting rods 43 are fixed at the bottom of the inclined block 2 42. The lifting rods 43 pass through the support plate 45 fixed to the inner wall of the hollow box 20. The bottom of the inclined block 2 42 is connected to the support plate 45 and the top of the air cylinder A46 with the return spring 44. The return spring 44 is respectively sleeved on the outside of the lifting rod 43 and the piston lifting rod 47.

[0036] The lifting rod 43 and the return spring 44 work together. When the inclined block 2 42 moves down, the return spring 44 is compressed and the lifting rod 43 also slides down. When the inclined block 1 41 moves away, it can drive the inclined block 2 42 to return to its original position, thereby causing the piston rod 410 to return to its original position. The same applies when moving away from the insertion point, which will not be described in detail here.
