Description

Technical Field

[0001] This utility model relates to the field of wave soldering liquid guiding technology, and to a wave soldering liquid guiding device. Background Technology

[0002] The flow of molten solder in wave soldering is a key step in ensuring soldering quality. Its core is to control the flow state of molten solder by rationally designing the flow guide structure, so that it can evenly and stably cover the solder pads, while reducing oxide residue and soldering defects.

[0003] Currently, during the wave soldering process, the height of the ripples can easily vary and is difficult to detect, which can easily lead to excessive solder on the pads, thus affecting the normal use of the pads and corner electronic components.

[0004] To address the aforementioned issues, this application proposes a wave soldering liquid guiding device. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a wave soldering liquid guiding device.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a wave soldering liquid guiding device, including a bracket installed on a wave soldering device, wherein an adjustment structure is provided on the bracket;

[0007] The adjustment structure includes an adjustment block and a threaded rod rotatably connected to the bracket.

[0008] The regulating block is equipped with a peak measuring structure;

[0009] The peak measuring structure includes a mounting block installed at the bottom of the adjusting block. A support rod is installed on one side of the mounting block, a rotating plate is movably sleeved on the support rod, and a fixing block is installed on the support rod. A passage groove is opened on the side of the fixing block near the rotating plate. A spring is installed on the fixing block through the passage groove. A movable rod is installed at one end of the spring. The movable rod is movably inserted into the fixing block through the passage groove. A stop rod is installed at the other end of the movable rod. The stop rod movably passes through the fixing block. A contact switch is installed on the side of the mounting block near the stop rod.

[0010] The wave soldering device is equipped with an alarm, which is electrically connected to a contact switch.

[0011] A hemisphere is installed at one end of the abutment near the rotating plate. The hemisphere contacts the rotating plate, and the hemisphere facilitates the return of the rotating plate to its original position.

[0012] The threaded rod is threadedly connected to the adjusting block, and a limit rod is installed on the bracket. The limit rod is movably inserted into the adjusting block to facilitate the adjustment of the rotating plate position.

[0013] The adjusting block has a through threaded hole, and the threaded rod is threadedly connected to the adjusting block through the threaded hole. The threaded hole facilitates the rotation of the threaded rod.

[0014] A limiting hole is provided through the adjusting block, and the limiting rod is movably inserted into the adjusting block through the limiting hole. By providing the limiting hole, the rotation of the adjusting block is minimized.

[0015] A rotating block is installed at the top of the threaded rod, which facilitates the rotation of the threaded rod.

[0016] The fixing block has a through hole that communicates with the passage groove. The abutment is movably inserted into the fixing block through the through hole, and the through hole is provided for the abutment to pass through.

[0017] The support rod is threaded with a nut, one side of which contacts one side of the rotating plate. The nut facilitates the disassembly and replacement of the rotating plate.

[0018] The beneficial effects of this utility model are:

[0019] By setting up a peak measuring structure, when the peak becomes higher, it touches the rotating plate. With the help of the moving peak, the rotating plate is pushed, thus causing the rotating plate to rotate. The rotating plate prevents the side of the rotating plate from pressing the movable rod, and the moving rod no longer presses the contact switch, causing the alarm to sound. This achieves the purpose of enabling staff to quickly detect the problem and minimizes the contact of too much solder on the pads, which would affect the normal use of the pads and the corner electronic components.

[0020] By setting an adjustment structure, rotating the rotating block causes the threaded rod to rotate, which in turn causes the adjusting block to move up or down, thereby causing the rotating plate to make fine adjustments to adapt to different crest heights. Attached Figure Description

It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0033] Reference Figure 1-4A wave soldering liquid guiding device includes a bracket 1 mounted on a wave soldering device. An adjustment structure 2 is provided on the bracket 1. The adjustment structure 2 includes an adjustment block 203 and a threaded rod 201 rotatably connected to the bracket 1. A peak measuring structure 3 is provided on the adjustment block 203. The peak measuring structure 3 includes a mounting block 301 mounted on the bottom of the adjustment block 203. A support rod 302 is mounted on one side of the mounting block 301. A rotating plate 303 is movably sleeved on the support rod 302. A fixing block 304 is mounted on the support rod 302. A passage groove 305 is opened on the side of the fixing block 304 near the rotating plate 303. A spring 306 is mounted on the fixing block 304 through the passage groove 305. A movable rod 309 is mounted on one end of the spring 306. The movable rod 309 is movably inserted into the fixing block 304 through the passage groove 305. A stop rod 307 is mounted on the other end of the movable rod 309. A contact switch 308 is installed on the side of the mounting block 301 near the abutment rod 307, and an alarm 310 is installed on the wave soldering device. The alarm 310 is electrically connected to the contact switch 308. According to the above technical solution, specifically, when the wave peak becomes higher, the wave peak touches the rotating plate 303. With the help of the moving wave peak, the rotating plate 303 is pushed, thereby causing the rotating plate 303 to rotate. The side of the rotating plate 303 no longer presses the movable rod 309, thereby causing the spring 306 to be no longer compressed. Therefore, the movable rod 309 is moved. The movement of the movable rod 309 drives the movement of the abutment rod 307, which in turn no longer presses the contact switch 308, causing the alarm 310 to sound. This achieves the purpose of allowing the staff to quickly notice the problem and minimize the contact of too much solder on the pads, which would affect the normal use of the pads and the corner electronic components.

[0034] Among them, the contact switch 308 is an Omron D2F-L manufactured by Omron Corporation, and the alarm 310 is a Patlite LHV manufactured by Patlite (Shanghai) Electronics Co., Ltd. The wiring connection between the two can be reasonably set according to the actual situation, and the signal transmission method of the two is existing technology.

[0035] Reference Figure 5 The fixing block 304 has a through hole 312 that communicates with the passage groove 305. The abutment 307 is movably inserted into the fixing block 304 through the through hole 312, and the through hole 312 is used for the smooth passage of the abutment 307.

[0036] Reference Figure 3 The support rod 302 is threaded with a nut 3021. One side of the nut 3021 contacts one side of the rotating plate 303, and the nut 3021 facilitates the disassembly and assembly of the rotating plate 303.

[0037] Reference Figure 4A hemisphere 311 is installed at one end of the stop rod 307 near the rotating plate 303. The hemisphere 311 contacts the rotating plate 303. It should be noted that the movable rod 309 will not leak out of the passage groove 305, and the hemisphere 311 facilitates the rotation plate 303 to return to its original position. Figure 2 The state.

[0038] Reference Figure 1 and Figure 2 The threaded rod 201 is threadedly connected to the adjusting block 203. A limit rod 204 is installed on the bracket 1, and the limit rod 204 is movably inserted into the adjusting block 203. A threaded hole 205 is provided through the adjusting block 203, and the threaded rod 201 is threadedly connected to the adjusting block 203 through the threaded hole 205. A limit hole 206 is provided through the adjusting block 203, and the limit rod 204 is movably inserted into the adjusting block 203 through the limit hole 206. A rotating block 202 is installed at the top of the threaded rod 201. Specifically, by rotating the rotating block 202, the threaded rod 201 is rotated. The rotation of the threaded rod 201 causes the adjusting block 203 to move up or down, thereby causing the rotating plate 303 to be finely adjusted to adapt to different peak heights.

[0039] Working principle:

[0040] The wave soldering liquid guiding device rotates the rotating block 202, which drives the threaded rod 201 to rotate. The rotation of the threaded rod 201 drives the adjusting block 203 to move up or down, thereby driving the rotating plate 303 to make fine adjustments to adapt to different wave heights.

[0041] This wave soldering fluid guiding device, when the wave crest becomes higher, touches the rotating plate 303. With the help of the moving wave crest, the rotating plate 303 is pushed, thereby causing the rotating plate 303 to rotate. The rotating plate 303 prevents its side from pressing the movable rod 309, thus relieving the pressure on the spring 306. As a result, the movable rod 309 moves, which in turn moves the stop rod 307, thus relieving the pressure on the contact switch 308 and causing the alarm 310 to sound. This achieves the purpose of allowing staff to quickly detect the problem and minimize the contact of too much solder on the pads, which could affect the normal use of the pads and the plug-in electronic components.
