[0001] The utility model relates to the technical field of electronic chip processing, in particular to an electronic chip welding auxiliary tooling. Background Art

[0002] When soldering electronic chips, one usually holds the circuit board with one hand and keeps the electronic components on the circuit board with the other hand to ensure that the electronic components are installed in the specified position. The pins of the electronic components pass through the circuit board. The electronic components are on the front of the circuit board and the pins are on the back of the circuit board. In order to facilitate soldering, electronic chip soldering auxiliary tooling is required.

[0003] The patent specification with announcement number CN212264804U discloses a manual soldering tool for processing electronic chips, including a base plate fixedly connected to an external workbench, on which a tool body is detachably mounted, the upper surface of the tool body is an arc surface and is provided with a special-shaped mounting groove for mounting an electronic chip frame, the inner bottom of the special-shaped mounting groove is an inclined bottom surface matching the electronic chip frame, and the upper edges on both sides of the special-shaped mounting groove are provided with taking grooves for facilitating the taking of the electronic chip frame; the utility model has reasonable design, simple structure, and convenient use, and assists staff to efficiently and high-quality complete the welding of the electronic chip frame and several small accessories, and reasonably opens a special-shaped mounting groove at the upper end of the tool body, the special-shaped mounting groove is the same shape as the electronic chip frame, so as to fix the electronic chip frame, and at the same time, in order to prevent the electronic chip frame from shaking during installation, the frame can complete the welding stably and reliably.

[0004] However, in the implementation of relevant technologies, it was found that the manual soldering tool for processing electronic chips designed above has the following problems: in the prior art, the electronic chip frame is fixed by cooperating with components such as special-shaped mounting grooves. Since the back of the circuit board faces upward during soldering and the front of the circuit board faces the bottom wall of the mounting groove, there is no force to position the electronic components on the front of the circuit board during soldering. The pins may be touched too hard during soldering, causing the electronic components to fall into the mounting groove. In view of this, an electronic chip soldering auxiliary tool is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an electronic chip welding auxiliary tooling.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electronic chip welding auxiliary tooling, comprising a mounting seat, a control terminal is embedded on one side of the top of the mounting seat, and a limiting hole is provided at the bottom end of the mounting seat, and a lifting mechanism is provided inside the limiting hole;

[0007] The lifting mechanism includes a lifting rod, which is slidably connected to the inside of the limiting hole, and the outer wall of the lifting rod that penetrates into the limiting hole is sleeved with a spring, the bottom end of the lifting rod is fixed with a connecting block, and a permanent magnet is connected below the connecting block, a limiting block is sleeved below the permanent magnet, and an iron core is fixed to the bottom end of the limiting block, and a coil is sleeved on the outside of the iron core, and magnetism is generated when the coil fixed to the mounting seat is energized, so that the iron core inside the coil generates magnetic force and repels the permanent magnet, allowing the connecting block to push the lifting rod up, so that the electronic chip frame can be supported, and at the same time, the permanent magnet can maintain vertical sliding through the limiting block to avoid offset.

[0008] As a further description of the above technical solution: the mounting seat forms an elastic structure between the spring and the connecting block, and a sliding structure is formed between the spring and the lifting rod. Through the elastic expansion and contraction of the spring, the connecting block is pushed after power failure to reset the lifting rod, which facilitates the disassembly and assembly of the electronic chip frame.

[0009] As a further description of the above technical solution: a lifting plate is fixed to one end of the lifting rod passing through the limiting hole, and a flexible pad is connected to the top of the lifting plate. The lifting rod supports the electronic chip frame from the bottom through the lifting plate and the flexible pad, thereby preventing the electronic components from detaching after welding, and preventing the lifting plate from being too hard to cause damage to the electronic components through the flexible pad.

[0010] As a further description of the above technical solution: sliding grooves are opened on both sides of the interior of the mounting seat, and a pressing rod is slidably connected inside the sliding groove. The electronic chip frame is clamped and fixed by the pressing rod and the lifting plate to avoid loosening during the welding process. At the same time, the pressing rod slides through the sliding groove to facilitate the conditional position to avoid blocking the welding position of the electronic component.

[0011] As a further description of the above technical solution: a mounting shell is fixed on one side of the outer wall of the mounting seat, and a clamping mechanism is arranged inside the mounting shell. The clamping mechanism is supported and fixed by the mounting shell, and at the same time has a certain protective effect.

[0012] As a further description of the above technical solution: the clamping mechanism includes a micro motor, which is embedded in one side of the interior of the mounting shell, and the power output end of the micro motor is connected to a bidirectional threaded rod, the outer wall of the bidirectional threaded rod is slidably connected to a sliding plate, and a clamping plate is fixed to one side of the sliding plate, and the outer wall of the clamping plate is connected to a protective pad, and the bidirectional threaded rod is driven by the micro motor, so that the two groups of sliding plates drive the corresponding clamping plates to slide relative to each other, thereby clamping and fixing the electronic chip frame, maintaining the accurate position and avoiding loosening during the welding process.

[0013] As a further description of the above technical solution: the sliding plate forms a sliding structure with the mounting shell through the bidirectional threaded rod, and a sliding structure is formed between the sliding plate and the sliding groove. The sliding plate axially penetrates the sliding groove and is fixed to the clamping plate, so that the sliding plate and the clamping plate can slide stably.

[0014] The utility model has the following beneficial effects:

[0015] The utility model discloses an electronic chip welding auxiliary tooling. When the electronic chip frame is placed inside a mounting seat with the welding surface facing downward, the iron core is magnetized by an energized coil. The magnetic poles of the iron core are the same as those of the permanent magnet, thereby generating a repulsive force, allowing the permanent magnet to stably slide along a limit block to avoid deviation or shaking, thereby allowing the connecting block to drive the lifting rod to rise, allowing the lifting plate and the flexible pad to fit the bottom end of the electronic chip frame, thereby preventing the electronic components from being separated or loosened after welding. After welding is completed, the coil is disconnected, and the lifting rod is reset under the elasticity of the spring.

[0016] The utility model discloses an auxiliary tooling for electronic chip welding. When the coil is not energized, the pressing rod is pushed to slide along the slide groove to reserve space for inserting the electronic chip frame into the mounting seat. Then the pressing rod is slid to correspond to the non-welding area of ​​the electronic chip frame, and the coil is energized through the control end. Then the lifting plate and the pressing rod are used to clamp the electronic chip frame to avoid shaking during the welding process, which may cause the electronic chip to loosen. The two-way threaded rod is driven to rotate by a micro motor, and the rotating two-way threaded rod pushes the two sliding plates to slide relative to each other, and drives the clamping plate to clamp the electronic chip frame, thereby improving the stability of the welding process and avoiding damage caused by excessive clamping through the protective pad.

[0023] Reference Figure 1-4 The utility model provides an electronic chip welding auxiliary tooling: comprising a mounting seat 1, a control terminal 2 is embedded on one side of the top of the mounting seat 1, a limiting hole 3 is provided at the bottom end of the inner part of the mounting seat 1, and a lifting mechanism 4 is arranged inside the limiting hole 3; the lifting mechanism 4 comprises a lifting rod 401, the lifting rod 401 is slidably connected to the inside of the limiting hole 3, a spring 407 is sleeved on the outer wall of one end of the lifting rod 401 that penetrates into the limiting hole 3, a connecting block 402 is fixed to the bottom end of the lifting rod 401, and a permanent magnet is connected below the connecting block 402 403, a limit block 405 is sleeved under the permanent magnet 403, an iron core 404 is fixed at the bottom end of the limit block 405, and a coil 406 is sleeved outside the iron core 404. When the coil 406 fixed to the mounting seat 1 is energized, magnetism is generated, so that the iron core 404 inside the coil 406 generates magnetic force and repels the permanent magnet 403, allowing the connecting block 402 to push the lifting rod 401 to rise, so that the electronic chip frame can be supported, and at the same time, the permanent magnet 403 is kept sliding vertically through the limit block 405 to avoid deviation.

[0024] As a further implementation scheme of the above technical scheme: the mounting seat 1 forms an elastic structure with the connecting block 402 through the spring 407, and a sliding structure is formed between the spring 407 and the lifting rod 401. Through the elastic expansion and contraction of the spring 407, the connecting block 402 is pushed after power failure to reset the lifting rod 401, which is convenient for disassembly and assembly of the electronic chip frame.

[0025] As a further implementation scheme of the above technical scheme: a lifting plate 5 is fixed to one end of the lifting rod 401 passing through the limiting hole 3, and a flexible pad 6 is connected to the top of the lifting plate 5. The lifting rod 401 supports the electronic chip frame from the bottom through the lifting plate 5 and the flexible pad 6, thereby preventing the electronic components from being detached after welding, and preventing the lifting plate 5 from being too hard to cause damage to the electronic components through the flexible pad 6.

[0026] In specific implementation, when the electronic chip frame is placed inside the mounting base 1, the control coil 406 is energized through the control end 2 to start. After the coil 406 is energized, the iron core 404 generates magnetism, so that the permanent magnet 403 slides along the limit block 405 to avoid offset and allow the connecting block 402 to drive the lifting rod 401 to rise, and allow the lifting plate 5 and the flexible pad 6 to rise to support the electronic chip frame, so as to avoid the loosening of the electronic components after welding. When the welding is completed, the coil 406 is de-energized and the lifting rod 401 is reset through the elastic push of the spring 407. The limit hole 3 is smaller than the spring 407, which is convenient for limiting the spring 407 to prevent loosening.

[0027] As a further implementation scheme of the above technical scheme: slide grooves 7 are opened on both sides of the interior of the mounting seat 1, and a pressing rod 8 is slidably connected inside the slide groove 7. The electronic chip frame is clamped and fixed by the pressing rod 8 and the lifting plate 5 to avoid loosening during the welding process. At the same time, the pressing rod 8 slides through the slide groove 7 to facilitate the conditional position to avoid blocking the welding position of the electronic components.

[0028] As a further implementation scheme of the above technical scheme: a mounting shell 9 is fixed to one side of the outer wall of the mounting seat 1, and a clamping mechanism 10 is arranged inside the mounting shell 9. The clamping mechanism 10 is supported and fixed by the mounting shell 9, and at the same time has a certain protective effect.

[0029] As a further implementation scheme of the above technical scheme: the clamping mechanism 10 includes a micro motor 1001, which is embedded in one side of the inner part of the mounting shell 9, and the power output end of the micro motor 1001 is connected to a bidirectional threaded rod 1002, and the outer wall of the bidirectional threaded rod 1002 is slidably connected to a sliding plate 1003, and a clamping plate 1004 is fixed to one side of the sliding plate 1003, and the outer wall of the clamping plate 1004 is connected to a protective pad 1005. The bidirectional threaded rod 1002 is driven by the micro motor 1001, so that the two groups of sliding plates 1003 drive the corresponding clamping plates 1004 to slide relative to each other, thereby clamping and fixing the electronic chip frame, maintaining the accurate position and avoiding loosening during the welding process.

[0030] As a further implementation scheme of the above technical scheme: the sliding plate 1003 forms a sliding structure with the mounting shell 9 through the bidirectional threaded rod 1002, and the sliding plate 1003 and the slide groove 7 form a sliding structure. The sliding plate 1003 axially penetrates the slide groove 7 and is fixed to the clamping plate 1004, so that the sliding plate 1003 and the clamping plate 1004 can slide stably.

[0031] During specific implementation, the electronic chip frame is placed in the reserved space by sliding the pressing rod 8 along the slide groove 7, and at the same time slides to the position of the electronic chip without soldered electronic components, and the electronic chip frame is clamped and limited under the lifting of the lifting plate 5 to prevent loosening or shaking during the welding process, which may cause the electronic components soldered at the bottom to fall off. At the same time, the micro motor 1001 drives the bidirectional threaded rod 1002, so that the two sliding plates 1003 drive the corresponding clamping plates 1004 along the slide groove 7 to clamp and fix the electronic chip frame from both sides, thereby further achieving stability. At the same time, the protective pad 1005 prevents the clamping plate 1004 from excessive clamping and causing damage to the electronic chip frame.
