Description

Technical Field

[0001] The utility model belongs to the technical field of furnace temperature detection, and in particular relates to a wave soldering furnace temperature detection carrier. Background Art

[0002] Wave soldering furnace refers to a furnace that sprays molten soft solder (lead-tin alloy) into a solder wave crest as required by the design through an electric pump or electromagnetic pump. It can also be formed by injecting nitrogen into the solder pool, so that a printed circuit board pre-installed with components passes through the solder wave crest, achieving soft soldering of mechanical and electrical connections between the component terminals or pins and the printed circuit board pads.

[0003] Although the existing wave soldering furnace temperature detection carrier can drive the thermometer to move horizontally in the furnace during use, since the thermometer is fixedly installed on the detection carrier, the thermometer can only be detected on the same horizontal line in the furnace during the movement, thereby reducing the detection range and failing to better detect the temperature in the furnace, which is inconvenient for people to use.

[0022] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] like Figures 1-8 As shown, a wave soldering furnace temperature detection carrier includes an installation box 1, a thermometer 3 and a driving mechanism for driving the thermometer 3 to move left and right are provided inside the installation box 1, a limit rod 8 is installed inside the installation box 1, a limit plate 9 is provided on the outside of the limit rod 8, and the thermometer 3 is fixed on the top of the limit plate 9. The driving mechanism includes a rotating rod 4 rotatably connected to the installation box 1, a rotating column 5 installed on the outside of the rotating rod 4, a wave groove 6 provided on the outside of the rotating column 5, and a ball 7 slidably connected to the inside of the wave groove 6, a fixing rod 10 fixedly connected to the bottom of the limit plate 9 is installed on the ball 7, a strip opening 11 is provided on the top of the installation box 1, and the temperature measuring end of the thermometer 3 extends to the outside of the installation box 1 through the strip opening 11. The thermometer is an industrial thermometer, and the thermometer is wirelessly connected to the detection system, so that the staff can observe the temperature in the furnace in real time from the outside;

[0024] The top of one of the fixed plates 12 is rotatably connected to a driving rod 21, and a support plate 23 is installed on one side of the fixed plate 12. The interior of the support plate 23 is rotatably connected to a connecting rod 24. A first bevel gear 22 is installed on the outside of the driving rod 21, and one end of the connecting rod 24 is installed with a second bevel gear 26 that meshes with the first bevel gear 22. A moving groove 25 is opened inside the rotating rod 4, and the moving block 2 is slidably connected inside the moving groove 25. The other end of the connecting rod 24 extends into the moving groove 25 and is fixedly connected to one side of the moving block 2. A driving wheel 27 is installed on the outside of the driving rod 21. The moving groove 25 and the moving block 2 are both square structures, so that when the connecting rod 24 rotates, the rotating rod 4 is driven to rotate;

[0025] Both sides of the installation box 1 are equipped with a fixing mechanism, which includes a fixing plate 12, a mounting cavity 13 provided in the fixing plate 12, a slide 14 slidably connected to the mounting cavity 13, and a card plate 15 installed on one side of the slide plate 14 and extending to the outside of the fixing plate 12. The other side of the slide plate 14 is equipped with a plurality of springs 16 fixedly connected to the inner wall of the mounting cavity 13; the other two sides of the installation box 1 are equipped with a telescopic mechanism used in conjunction with the fixing mechanism, the telescopic mechanism includes a fixed cylinder 17 installed on the outside of the installation box 1, two limit blocks 18 slidably connected in the fixed cylinder 17, and two movable plates 19 installed on one side of the two limit blocks 18, one end of the two movable plates 19 extends to the outside of the fixed cylinder 17 and is fixedly connected to one side of the two fixing plates 12 respectively, the top of the fixed cylinder 17 is provided with a plurality of mounting holes 20, and the top of the limit block 18 is provided with a threaded hole used in conjunction with the mounting holes 20. When the distance between the plates 15 is adjusted, the two card plates 15 can be pulled toward or away from each other. In the process of pulling the card plates 15, the two adjacent movable plates 19 will drive the two adjacent limit blocks 18 to move. At the same time, the movable block 2 will move inside the movable groove 25. When it is adjusted to the appropriate position, the bolt is screwed into one of the mounting holes 20 corresponding to the threaded holes, and the mounting hole 10 is fixed with the threaded hole, so that the limit block 18 is fixed in the mounting cylinder 20. When adjusting the position of the card plate 15, it is necessary to make the driving wheel 27 fit tightly with the outer shell of the conveying rail. When the card plate 15 contacts the conveying rail and the driving wheel 27 has not yet fit with the outer shell of the conveying rail, the card plate 15 can be squeezed. At this time, the card plate 15 will push the slide plate 14 to slide inside the mounting cavity 13, thereby squeezing multiple springs 16 until the driving wheel 27 fits with the outer shell of the conveying rail;

[0026] Working principle: During use, the distance between the two card plates 15 can be adjusted according to the width of the transmission track. When adjusted to the appropriate position, the detection carrier is clamped between the two transmission tracks, so that one side of the driving wheel 27 is tightly fitted with the shell on which the transmission track is installed. When the transmission track drives the detection carrier to move, the driving rod 27 fits tightly with the shell, and the driving wheel 27 rotates under the drive of the driving wheel 27. The driving rod 21 drives the first bevel gear 22 to rotate under the drive of the driving wheel 27. Under the engagement of the first bevel gear 22 and the second bevel gear 26, the connecting rod 24 drives the rotating rod 4 to rotate. Driven by the rotating rod 4, the rotating column 5 will rotate, causing the ball 7 to reciprocate in the wave groove 6, thereby driving the fixed rod 10 to reciprocate. Driven by the fixed rod 10, the limit plate 10 drives the thermometer 3 to reciprocate, which can expand the detection range of the thermometer and better detect the temperature in the furnace.

[0027] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
