DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figure 1 , Figure 4 , Figure 5 , Figure 6 ,and Figure 7As shown, a circuit board component welding auxiliary device described in the present invention includes a base plate 1, a driving structure 2 installed on the base plate 1, a flip structure 3 connected to the driving structure 2, a hinge 4 connected to the flip structure 3, a limiting structure 5 arranged on the flip structure 3, an adjusting structure 6 arranged on the flip structure 3, a placement structure 7 connected to the flip structure 3, and a welding gun 8 arranged on the placement structure 7. The driving structure 2 includes a mounting frame 201 and a connecting rod 202 rotatably connected to the top of the mounting frame 201. Two mounting frames 201 are fixedly connected to the surface of the base plate 1, and the flip structure 3 is matched on the connecting rod 202. The mounting frame 201 is internally slidably connected to a rotating plate 204, and the rotating plate 204 is connected to the mounting frame 201. A first spring 203 is fixedly connected between the inner walls of the mounting frame 201, the connecting rod 202 is rotatably connected to the rotating plate 204, a driving rod 205 is slidably connected to the top of the mounting frame 201, a driving groove 206 is provided inside the driving rod 205, the connecting rod 202 is slidably connected to the driving groove 206, a gear 207 is fixedly connected to the middle position of the driving rod 205, a limiting rod 208 is fixedly connected to the inner wall of the mounting frame 201, the limiting rod 208 and the gear teeth of the gear 207 are engaged with each other, the end of the driving rod 205 is in contact with the rotating plate 204, a welding gun 8 is connected to the mounting frame 201 through a placement structure 7, the two mounting frames 201 are symmetrically arranged, and the end of the driving rod 205 is a "T"-shaped structure;After the circuit board is fixed, it is necessary to flip the circuit board together with the installation frame 301 by 180 degrees. Just press the driving rod 205 inwards. And because the driving rod 205 is provided with a driving groove 206 inside, the connecting rod 202 rotatably connected to the mounting frame 201 and the driving groove 206 slide relative to each other. At the same time, the end of the driving rod 205 drives the rotating plate 204 to squeeze the first spring 203. At the same time, the driving rod 205 drives the gear 207 in the middle position to move, so that the limiting rod 208 on the inner wall of the mounting frame 201 no longer conflicts with the gear teeth of the gear 207. Then the driving rod 205 is rotated. Since the connecting rod 202 is provided with four protrusions, the driving rod 205 and the connecting rod 202 are effectively prevented from sliding relative to each other. The drive rod 205 drives the connecting rod 202 to rotate, and the other end of the connecting rod 202 is connected to the installation frame 301. The installation frame 301 rotates through the rotating shaft 304 fixed on the installation frame 201, so that the connecting rod 202 drives the installation frame 301 to rotate. After the installation frame 301 drives the circuit board to flip 180 degrees, the drive rod 205 is released again, and the rotating plate 204 drives the driving rod 205 to move outward under the reset action of the first spring 203, and the driving rod 205 drives the gear 207 to move, and then the gear teeth of the gear 207 are again in conflict with the limiting rod 208, so as to prevent the driving rod 205 from rotating under the gravity of the installation frame 301, and then complete the fixation of the flipped installation frame 301, and the stability is strong. ;

[0034] Specifically, Figure 1-Figure 6 As shown, the flip structure 3 includes a mounting frame 301 and a cover plate 302 connected to the edge of the mounting frame 301. The mounting frame 301 is provided between two mounting frames 201. The end of the connecting rod 202 is fixedly connected to the side of the mounting frame 301. The top of the other mounting frame 201 is fixedly connected to a rotating shaft 304, and the mounting frame 301 is rotatably connected to the rotating shaft 304.

The cover plate 302 has a rubber pad 303 fixedly connected to one side of the cover plate 302, and a handle 305 fixedly connected to the other side of the cover plate 302. When a plurality of circuit boards are placed on the first slide bar 603 and the second slide bar 604, the cover plate 302 only needs to be rotated by the hinge 4 so that the rubber pad 303 on the inner side of the cover plate 302 contacts the circuit board. The setting of the rubber pad 303 can protect the circuit board, and then the cover plate 302 can be rotated upward by the handle 305. The operation is simple and flexible.

[0035] Specifically, Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the limiting structure 5 includes a limiting block 501 and a connecting strip 502 fixedly connected to the end of the limiting block 501, the internal sliding connection of the installation frame 301 is connected to the limiting block 501, a first tension spring 503 is fixedly connected between the limiting block 501 and the inner wall of the installation frame 301, and a pressing block 504 is fixedly connected to the end of the connecting strip 502, and the pressing block 504 is slidably connected to the inner wall of the installation frame 301, and a limiting groove 505 is provided on the cover plate 302, and the cross section of the limiting groove 505 is an "L"-shaped structure, and the top of the limiting block 501 is provided with an inclined surface; when the end of the cover plate 302 rotates to the end of the installation frame 301, due to the limiting groove 505 provided at the front end of the cover plate 302, the edge of the limiting groove 505 squeezes the limiting block 501 on the installation frame 301, and the edge of the limiting groove 505 and the inclined surface of the top of the limiting block 501 slide and cooperate, thereby driving The movable limit block 501 slides toward the center direction of the installation frame 301 until the top of the limit block 501 no longer conflicts with the edge of the limit groove 505. At this time, the top of the limit block 501 slides into the limit groove 505, and at the same time, under the reset action of the first tension spring 503, the limit block 501 and the connecting strip 502 are driven to slide toward the inside of the installation frame 301, so that the convex portion at the top of the limit block 501 conflicts with the inner wall of the limit groove 505, thereby effectively fixing the cover plate 302 with strong firmness. At the same time, the cover plate 302 drives the rubber pad 303 to press the circuit board. When it is necessary to open the cover plate 302, it is only necessary to press the pressing block 504, and the pressing block 504 drives the connecting strip 502 and the limit block 501 to slide toward the center direction of the installation frame 301, so that the convex portion at the top of the limit block 501 no longer conflicts with the inner wall of the limit groove 505, and then the cover plate 302 is rotated upward by the handle 305. It is easy to operate and has strong flexibility.

[0036] Specifically, Figure 1-Figure 8As shown, the adjustment structure 6 includes two first guide rods 601 and four pairs of first sliders 602 slidably connected between the two first guide rods 601. Two first guide rods 601 are fixedly connected to the inner wall of the installation frame 301, and the first sliders 602 on one side are slidably connected to the first sliders 603. One end of the first slider 603 is fixedly connected to the second slider 607, and the second slider 607 is slidably connected to the first slider 602. A rubber block 608 is fixedly connected to the second slider 607, and the rubber block 608 is slidably connected to the first slider 602. The rubber block 608 abuts against the first guide rod 601. The other end of the rod 603 is threadedly connected with a connecting cover 606, the end of the first slide bar 603 is slidably connected with the second slide bar 604, one end of the second slide bar 604 abuts against the connecting cover 606, the other end of the second slide bar 604 is fixedly connected to the first slider 602 on the other side, and a second spring 605 is fixedly connected between the end of the second slide bar 604 and the inner wall of the first slide bar 603, wherein the two pairs of the first slide bars 603 and the second slide bars 604 are fixedly connected with a support plate 609, and the two first guide rods 601 are symmetrically arranged; place the bottom plate 1 on the desktop, and then adjust the position of the first slide bar 603, just hold the first slide bar with one hand 603, and push the first slide bar 603 to the middle position, so that the end of the second slide bar 604 slides relatively with the inner wall of the first slide bar 603, and the second spring 605 is compressed at the same time. At this time, the other end of the first slide bar 603 drives the second slider 607 and the rubber block 608 to slide along the inner wall of the first slider 602, so that the rubber block 608 no longer conflicts with the first guide rod 601, so that it is convenient to slide the two symmetrical first sliders 602 along the first guide rod 601, and then release the first slide bar 603, and then the rubber block 608 conflicts with the first guide rod 601 again under the reset action of the second spring 605. The setting of the connecting cover 606 is convenient for installing the second spring 605, thereby effectively fixing the positions of the first slide bar 603 and the second slide bar 604, and repeating the operation on the other first slide bars 603 until they are adjusted to the appropriate positions, and the two first slide bars 603 and the second slide bars 604 in the middle position of the installation frame 301 are fixedly connected with the support plate 609, and then one end of the circuit board is placed on the support plate 609, the middle is placed on the first slide bar 603 and the second slide bar 604, and the other end of the circuit board is placed on the edge of the installation frame 301 until the installation frame 301 is full of circuit boards, thereby effectively adjusting the positions of the first slide bar 603 and the second slide bar 604, which is convenient for adapting to circuit boards of different sizes and has strong flexibility.

[0037] Specifically, Figure 1 , Figure 2 and Figure 4-Figure 6As shown, the placement structure 7 includes two connecting plates 701 and a second guide rod 702 slidably connected between the two connecting plates 701, a second tension spring 703 is fixedly connected between the end of the second guide rod 702 and the connecting plate 701, the end of the rotating shaft 304 is fixedly connected to a mounting plate 704, the top of the mounting plate 704 is fixedly connected to a placement rack 705, and a welding gun 8 is engaged inside the placement rack 705; when soldering components to the circuit board, in order to avoid the problem of the welding wire being entangled when moving the welding wire, it is only necessary to pull the second guide rod 702 outward to make the second guide rod 702 The end of the rod 702 slides out from the connecting plate 701, and then the wire roller wrapped with the welding wire is put on the second guide rod 702, and then the second guide rod 702 is loosened, and the end of the second guide rod 702 slides back into the interior of the connecting plate 701 under the resetting action of the second tension spring 703, and then during the welding process, the wire roller wrapped with the welding wire can be moved back and forth through the second guide rod 702, avoiding the problem of inconvenient to take the welding wire. At the same time, the end of the rotating shaft 304 is installed with a placement rack 705 through the mounting plate 704, so that the welding gun 8 can be temporarily stored in the placement rack 705 during the welding process, which has strong flexibility.

[0038] When the present invention is in use, the bottom plate 1 is placed on a desktop, and then the position of the first slide bar 603 is adjusted. The first slide bar 603 only needs to be held with one hand and pushed toward the middle position, so that the end of the second slide bar 604 slides relatively with the inner wall of the first slide bar 603, and the second spring 605 is compressed at the same time. At this time, the other end of the first slide bar 603 drives the second slider 607 and the rubber block 608 to slide along the inner wall of the first slider 602, so that the rubber block 608 no longer conflicts with the first guide rod 601, thereby facilitating the two symmetrical first sliders 602 to slide along the first guide rod 601, and then the first slide bar 603 is released, and then the rubber block 608 is re-aligned with the first guide rod 601 under the reset action of the second spring 605. 01, the setting of the connecting cover 606 facilitates the installation of the second spring 605, thereby effectively fixing the position of the first slide bar 603 and the second slide bar 604, and repeating the operation on the other first slide bars 603 until they are adjusted to a suitable position, and the two first slide bars 603 and the second slide bars 604 in the middle of the installation frame 301 are fixedly connected with a support plate 609, and then one end of the circuit board is placed on the support plate 609, the middle is placed on the first slide bar 603 and the second slide bar 604, and the other end of the circuit board is placed on the edge of the installation frame 301 until the installation frame 301 is full of circuit boards, thereby effectively adjusting the position of the first slide bar 603 and the second slide bar 604, which is convenient for adapting to circuit boards of different sizes and has strong flexibility;

[0039] When multiple circuit boards are placed on the first slide bar 603 and the second slide bar 604, it is only necessary to rotate the cover plate 302 through the hinge 4 so that the rubber pad 303 on the inner side of the cover plate 302 contacts the circuit board. The setting of the rubber pad 303 can protect the circuit board. When the end of the cover plate 302 is rotated to the end of the installation frame 301, since the front end of the cover plate 302 is provided with a limiting groove 505, the edge of the limiting groove 505 squeezes the limiting block 501 on the installation frame 301, and the edge of the limiting groove 505 slides with the inclined surface at the top of the limiting block 501, thereby driving the limiting block 501 to slide toward the center direction of the installation frame 301 until the top of the limiting block 501 no longer conflicts with the edge of the limiting groove 505. At this time, the limiting block 5 01, the top of the limit block 501 slides into the limit groove 505, and at the same time, under the reset action of the first tension spring 503, the limit block 501 and the connecting strip 502 are driven to slide toward the inside of the installation frame 301, so that the convex part at the top of the limit block 501 conflicts with the inner wall of the limit groove 505, thereby effectively fixing the cover plate 302 with strong firmness. At the same time, the cover plate 302 drives the rubber pad 303 to press the circuit board. When it is necessary to open the cover plate 302, it is only necessary to press the pressing block 504, and the pressing block 504 drives the connecting strip 502 and the limit block 501 to slide toward the center direction of the installation frame 301, so that the convex part at the top of the limit block 501 no longer conflicts with the inner wall of the limit groove 505, and then the cover plate 302 is rotated upward by the handle 305, which is easy to operate and has strong flexibility.

[0040] After the circuit board is fixed, it is necessary to flip the circuit board together with the installation frame 301 by 180 degrees. Just press the driving rod 205 inwards. And because the driving rod 205 is provided with a driving groove 206 inside, the connecting rod 202 rotatably connected to the mounting frame 201 and the driving groove 206 slide relative to each other. At the same time, the end of the driving rod 205 drives the rotating plate 204 to squeeze the first spring 203. At the same time, the driving rod 205 drives the gear 207 in the middle position to move, so that the limiting rod 208 on the inner wall of the mounting frame 201 no longer conflicts with the gear teeth of the gear 207. Then the driving rod 205 is rotated. Since the connecting rod 202 is provided with four protrusions, the driving rod 205 and the connecting rod 202 are effectively prevented from sliding relative to each other. The drive rod 205 drives the connecting rod 202 to rotate, and the other end of the connecting rod 202 is connected to the installation frame 301. The installation frame 301 rotates through the rotating shaft 304 fixed on the installation frame 201, so that the connecting rod 202 drives the installation frame 301 to rotate. After the installation frame 301 drives the circuit board to flip 180 degrees, the driving rod 205 is released again, and the rotating plate 204 drives the driving rod 205 to move outward under the reset action of the first spring 203, and the driving rod 205 drives the gear 207 to move, and then the gear teeth of the gear 207 are again in conflict with the limiting rod 208, so as to prevent the driving rod 205 from rotating under the gravity of the installation frame 301, thereby completing the fixation of the flipped installation frame 301, and the stability is strong;

[0041] When soldering components to the circuit board, in order to avoid the problem of the welding wire getting tangled when moving the welding wire, it is only necessary to pull the second guide rod 702 outward to make the end of the second guide rod 702 slide out from the connecting plate 701, and then put the wire roller wrapped with the welding wire on the second guide rod 702, and then release the second guide rod 702. The end of the second guide rod 702 slides back into the interior of the connecting plate 701 under the resetting action of the second tension spring 703, and then during the welding process, the wire roller wrapped with the welding wire can be moved back and forth by the second guide rod 702, avoiding the problem of the welding wire being inconvenient to take. At the same time, the end of the rotating shaft 304 is installed with a placement rack 705 through the mounting plate 704, so that the welding gun 8 can be temporarily stored in the placement rack 705 during the welding process, which has strong flexibility.
