Description

Technical Field

[0001] This invention relates to the field of BTB terminal processing technology, and in particular to a precision BTB terminal automatic bending and straightening mechanism. Background Technology

[0002] Board-to-board connectors, also known in the industry as BTB connectors, are currently the connector products with the highest transmission capacity among all connector product types. As a high-precision multi-contact connector, BTB connectors are widely used in electronic products such as mobile phones and laptops for connecting components such as motherboards and flexible circuit boards inside electronic devices.

[0003] Current BTB connectors are tested using micro-needles, where the micro-needle tip contacts the test product to achieve connection testing. However, this connection testing structure suffers from the small diameter of the micro-needle tip, making it prone to bending. Existing BTB terminal correction mechanisms employ a unidirectional corrector, requiring multiple adjustments to achieve multi-directional correction, resulting in low correction efficiency. Summary of the Invention

[0004] This invention provides a precision automatic bending and straightening mechanism for BTB terminals, which solves the problem that existing BTB terminal straightening mechanisms use a single-direction straightener to adjust the direction multiple times for multi-directional straightening, resulting in low straightening efficiency.

[0005] On one hand, the present invention provides a precision BTB terminal automatic bending and straightening mechanism, comprising:

[0006] The base has an automatic BTB terminal conveying mechanism mounted on its upper surface and a correction component mounted in the middle of its center.

[0007] The corrective assembly includes an electric telescopic rod with arc-shaped brackets fixed to both sides. A rectangular frame is fixed to the top of each arc-shaped bracket, and a slider is slidably connected inside the rectangular frame. The movable rod of the electric telescopic rod is connected to the bottom of the slider. Multiple corrective blades are mounted on the side of the slider, and a toothed rod is fixed to the other side of the slider. An L-shaped bracket is fixed to the side of the rectangular frame, and a long gear is rotatably connected to the end of the L-shaped bracket. Two limiting blocks are fixed to the side of the rectangular frame, and a sliding rod is slidably connected through the limiting blocks. A connecting block is fixed to the side of the sliding rod, and multiple corrective blades are mounted on the side of the connecting block. A toothed rod is fixed to the bottom of the connecting block. This application, by setting up the corrective assembly, allows the electric telescopic rod to push the slider upward, at which point multiple corrective blades perform vertical correction. Furthermore, as the slider continues to rise, the connecting block drives multiple corrective blades to perform lateral correction. This linkage method ensures both the integrity and efficiency of the correction.

[0008] On the other hand, the first and second toothed rods are staggered, and the first and second toothed rods respectively mesh with the long gear.

[0009] On the other hand, the top and bottom of the first corrective blade are both set with double inclined surfaces, while the end of the second corrective blade near the first corrective blade is set with a single inclined surface.

[0010] On the other hand, a triangular pressure bar is fixed to the top of the connecting block.

[0011] On the other hand, the top of the rectangular frame is fitted with a grease-adding component for adding grease.

[0012] On the other hand, the grease application assembly includes a storage box one, a storage box two, and a sponge mounting frame two. The storage box one is fixed to the top of a rectangular frame and is connected to the storage box two via a soft rubber sleeve. A one-way valve is fitted to the top of the storage box two. The bottom of the storage box one is fixed to the sponge mounting frame one, and a sponge body one is installed inside the sponge mounting frame one. The sponge body one is connected to the storage box one via a hose one. The sponge mounting frame two is fixed to the side of the rectangular frame, and a sponge body two is installed on the side of the sponge mounting frame two. The sponge body two is connected to the storage box one via a hose two. By setting up the grease application assembly, grease can be applied to multiple straightening blades one when they move upward to the sponge body one, and grease can be applied to multiple straightening blades two when they move laterally to the sponge body two. In this way, lubrication during straightening can be improved, and the straightening blades one and two can be protected at the same time.

[0013] On the other hand, the second storage box is located on the movement trajectory of the triangular pressure rod.

[0014] On the other hand, a dust removal assembly is fitted to the side of the rectangular frame. This assembly includes a small bracket, a rotating rod bracket, and a fan. Both the small bracket and the rotating rod bracket are fixed to the side of the rectangular frame. An elastic telescopic rod is fixed to the side of the small bracket, and its side is connected to the fan via a universal joint. A rotating rod is rotatably connected inside the rotating rod bracket. A friction wheel is fixed to one end of the rotating rod, and a disc is fixed to the other end. A transmission rod is connected to the surface of the disc via a universal joint, and the other end of the transmission rod is connected to the fan via a universal joint. This application, by setting up the dust removal assembly, utilizes the linkage effect generated when the correction assembly is working to cause the fan to rotate in multiple directions, using irregular turbulence to clean dust or impurities adsorbed by electrostatic charge on the BTB terminals, preventing these impurities from affecting the correction effect of the first and second correction blades.

[0015] Preferably, the friction wheel is located on the motion trajectory of the toothed rod.

[0016] The advantages of this application are:

[0017] (1) This application sets up a correction component, and pushes the slider upward by an electric telescopic rod. At this time, multiple correction blades are used to perform vertical correction. Secondly, as the slider continues to rise, the connecting block will drive multiple correction blades to perform horizontal correction. The above linkage method is used to perform vertical and horizontal correction, which not only ensures the integrity of the correction but also improves the efficiency of the correction.

[0018] (2) By setting up a grease-adding component, the multiple straightening blades can be coated with grease when they move upward to the sponge body. At the same time, the multiple straightening blades can be coated with grease when they move laterally to the sponge body. This can improve the lubrication during the straightening process and protect the straightening blades.

[0019] (3) By setting up a dust removal component, the fan rotates in multiple directions through the linkage effect generated when working with the correction component. The irregular turbulence cleans the dust or impurities adsorbed by static electricity on the BTB terminal, preventing these impurities from affecting the correction effect of the first and second correction blades.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0035] Example 1, see Figures 1-6 This embodiment provides a precision BTB terminal automatic bending and straightening mechanism, including:

[0036] The base 100 has an automatic BTB terminal conveying mechanism 200 mounted on its upper surface and a correction component 300 mounted in the middle of its middle section.

[0037] The corrective assembly 300 includes an electrically operated telescopic rod 301. Arc-shaped supports 302 are fixed to both sides of the electrically operated telescopic rod 301. A rectangular frame 303 is fixed to the top of the two arc-shaped supports 302. A slider 304 is slidably connected inside the rectangular frame 303. The movable rod of the electrically operated telescopic rod 301 is connected to the bottom of the slider 304. Multiple corrective blades 305 are mounted on the side of the slider 304. A toothed rod 306 is fixed to the other side of the slider 304. An L-shaped support 307 is fixed to the side of the rectangular frame 303. A long gear 308 is rotatably connected to the end of the L-shaped support 307. Two limiters are fixed to the side of the rectangular frame 303. Block 309, the limiting block 309 has a sliding rod 310 that runs through and slides through it. A connecting block 311 is fixed to the side of the sliding rod 310. Multiple straightening blades 312 are mounted on the side of the connecting block 311. The top and bottom of the first straightening blade 305 are both set with double inclined surfaces. The end of the second straightening blade 312 near the first straightening blade 305 is set with a single inclined surface. A second toothed rod 313 is fixed to the bottom of the connecting block 311. The first toothed rod 306 and the second toothed rod 313 are staggered and mesh with the long gear 308 respectively. A triangular pressure rod 314 is fixed to the top of the connecting block 311. This application sets up a correction component 300, which pushes the slider 304 upward via an electric telescopic rod 301. At this time, multiple correction blades 305 perform vertical correction. Secondly, as the slider 304 continues to rise, the connecting block 311 drives multiple correction blades 312 to perform horizontal correction. By using the above-mentioned linkage method for both vertical and horizontal correction, the integrity of the correction is ensured and the efficiency of the correction is improved.

[0038] In practical use, the aforementioned equipment first transports the BTB terminals to the front end of the straightening assembly 300 via the automatic BTB terminal conveying mechanism 200. Then, the electric telescopic rod 301 is activated, pushing the slider 304 upwards within the rectangular frame 303. During this upward movement, multiple straightening blades 305 mounted on the side of the slider 304 vertically straighten the connection of the BTB terminals from bottom to top. As the slider 304 moves upwards, when it reaches halfway down the rectangular frame 303, the locking rod 306 engages with the long gear 308, causing the long gear 308 to rotate. At this point, the rotation of the long gear 308 causes the locking... The second toothed bar 313 moves, thereby driving the connecting block 311 to move laterally. Lateral correction is performed by the second straightening knife 312 mounted on its side, and vertical correction is performed by multiple first straightening knives 305. Lateral correction is performed in conjunction with multiple second straightening knives 312. During this process, while the first straightening knife (305) and the second straightening knife (312) are in contact with the BTB terminal, the component force generated by their inclined surface structure forms effective limit and support for the terminal in the vertical and horizontal directions, respectively, ensuring the positional stability of the terminal during the correction action. The above linkage method is used to perform vertical and horizontal correction, which not only ensures the integrity of the correction but also improves the efficiency of the correction.

[0039] Subsequently, the electric telescopic rod 301 retracts, causing the slider 304 to move downwards. At this time, the toothed rod 306 moves downwards, causing the long gear 308 to rotate in the opposite direction, resetting the connecting block 311. As the slider 304 moves downwards, the entire device is restored to its initial state.

[0040] Example 2, see Figures 1-7In this embodiment, based on Embodiment 1, a grease-adding component 400 for adding grease is fitted to the top of the rectangular frame 303. The grease-adding component 400 includes a first storage box 401, a second storage box 403, and a second sponge mounting frame 409. The first storage box 401 is fixed to the top of the rectangular frame 303 and is connected to the second storage box 403 via a soft rubber sleeve 402. A one-way valve 404 is fitted to the top of the second storage box 403. A sponge mounting frame 405 is fixed to the bottom of 01. A sponge body 406 is installed inside the sponge mounting frame 405. The sponge body 406 is connected to the storage box 401 via a hose 407. A second sponge mounting frame 409 is fixed to the side of the rectangular frame 303. A second sponge body 410 is installed on the side of the second sponge mounting frame 409. The second sponge body 410 is connected to the storage box 401 via a hose 408. The storage box 403 is located on the movement trajectory of the triangular pressure rod 314. This application, by setting a grease-adding component 400, allows grease to be applied to multiple straightening blades 305 when they move upwards to the sponge body 406. Simultaneously, grease is applied to multiple straightening blades 312 when they move laterally to the sponge body 410. This improves lubrication during straightening and protects both the straightening blades 305 and 312.

[0041] In practical use, based on the movement of Embodiment 1, as the connecting block 311 moves laterally, it drives the fixed triangular pressure rod 314 to move laterally. At this time, as the triangular pressure rod 314 moves, it squeezes the top of the storage box 403. With the cooperation of the one-way valve 404, the grease stored inside is injected into the sponge 406 and sponge 410 through hose 407 and hose 408 respectively to replenish the grease. As the slider 304 continues to rise, multiple straightening blades 305 will come into contact with sponge 406, and then multiple straightening blades 312 will come into contact with sponge 410. Grease can be applied to multiple straightening blades 305 and multiple straightening blades 312 at the same time. This can improve the lubrication during straightening and protect the straightening blades 305 and straightening blades 312.

[0042] Example 3, see Figures 1-8In this embodiment, based on Embodiment 1, a dust removal assembly 500 is mounted on the side of the rectangular frame 303. The dust removal assembly 500 includes a small bracket 501, a rotating rod bracket 502, and a fan 504. The small bracket 501 and the rotating rod bracket 502 are both fixed to the side of the rectangular frame 303. An elastic telescopic rod 503 is fixed to the side of the small bracket 501. The side of the elastic telescopic rod 503 is connected to the fan 504 via a universal joint. A rotating rod 505 is rotatably connected inside the rotating rod bracket 502. A friction wheel 506 is fixed to one end of the rotating rod 505, and a disc 507 is fixed to the other end of the rotating rod 505. A transmission rod 508 is connected to the surface of the disc 507 via a universal joint. The other end of the transmission rod 508 is connected to the fan 504 via a universal joint. The friction wheel 506 is located on the movement trajectory of the toothed rod 306. This application sets up a dust removal component 500, which, through the linkage effect generated when working with the correction component 300, causes the fan 504 to rotate in multiple directions, using irregular turbulence to clean the dust or impurities adsorbed by static electricity on the BTB terminals, preventing these impurities from affecting the correction effect of the first correction blade 305 and the second correction blade 312.

[0043] In specific use, based on Embodiment 1, as the toothed rod 306 rises, it comes into contact with the friction wheel 506. Under the action of friction, the friction wheel 506 rotates. The rotation of the friction wheel 506 drives the rotating rod 505 and the disc 507 on the side of the rotating rod 505 to rotate. Then, the transmission rod 508 connected to the side of the disc 507 via a universal joint transmits the rotational force to the fan 504. Since the fan 504 is connected to the elastic telescopic rod 503 via a universal joint, the fan 504 can swing in multiple directions. Through its multi-directional swing, the airflow becomes irregular, increasing the air delivery area to clean the dust or impurities adsorbed by static electricity on the BTB terminals, preventing these impurities from affecting the correction effect of the first correction blade 305 and the second correction blade 312.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
