[0003] When detecting the temperature of the reflow furnace, a furnace temperature tester needs to be sent into the furnace body. When the existing furnace temperature tester is in use, a battery needs to be installed inside. When installing, it is necessary to turn the screw connecting the cover plate and the housing with a screwdriver, and then separate the cover plate from the housing before the battery can be disassembled and assembled. This installation method is relatively cumbersome and not convenient for replacing the battery inside the furnace temperature tester. Content of the Utility Model

[0004] The purpose of the utility model is to provide an on-line monitoring device for the temperature curve of a reflow furnace to solve the problem that the existing furnace temperature tester is not convenient for replacing the battery proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An on-line monitoring device for the temperature curve of a reflow furnace, comprising: a body and a tension spring a. One side of the body is provided with a connector a, a battery is installed inside the body, and a connector b is installed on the other side of the body. It is characterized in that

[0006] Two groups of fixing plates are fixed on one side of the body close to the battery. A closing cover is slidably connected to the outside of the fixing plate.

[0012] Compared with the prior art, the beneficial effects of the reflow furnace temperature curve online monitoring device are:

[0013] 1. When testing the temperature of the reflow oven, the oven temperature tester needs to be sent into the oven body. When separating the closing cover from the body, the two sets of toggle rods are turned to rotate. When the protrusion at one end of the toggle rod rotates, it will slide in the rotating groove inside the closing cover and cross the limiting groove inside the fixed plate. When the protrusion enters the straight groove, the closing cover can be pulled up, and the protrusion will slide in the straight groove until it leaves the inside of the fixed plate, completing the separation of the closing cover and the body. At this time, the battery inside the body can be disassembled and assembled.

[0014] 2. When testing the temperature of the reflow oven, the furnace temperature tester needs to be sent into the furnace body. When using the furnace temperature tester, the thermocouple needs to be inserted into the joint a, and then the thermocouple is fixed to the outside of the measured workpiece. When it is necessary to remove multiple sets of thermocouples inserted on joint a, the push plate is pushed to move. The push plate will slide on the outside of the slide bar and pull the tension spring b to stretch it. When the push plate contacts the thermocouple plug connected to the joint a, it can push the multiple sets of thermocouple plugs to move and disconnect them from the joint a. In this way, the above operation can facilitate the centralized removal of the thermocouples connected to the online monitoring device of the reflow oven temperature curve.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 5 , the present invention provides a technical solution: an online monitoring device for the reflow furnace temperature curve, including: the body 1 and the tension spring a 8. A connector a 2 is installed on one side of the body 1, a battery 3 is installed inside the body 1, and a connector b 4 is installed on the other side of the body 1.

[0024] Two groups of fixing plates 5 are fixed on one side of the body 1 close to the battery 3. The outside of the fixing plate 5 is slidably connected with a closing cover 6. One side of the closing cover 6 is movably connected with a toggle lever 7 through a rotating shaft. A tension spring a 8 is fixed on one side of the toggle lever 7. One end of the tension spring a 8 is fixedly connected with a fixing block 9. One side of the fixing block 9 is fixedly connected with the closing cover 6; One end of the toggle lever 7 is fixedly connected with a convex block 10, and the outer shape of the convex block 10 is cylindrical. Rotating grooves 11 are opened on both sides of the closing cover 6, and the rotating grooves 11 are slidably connected with the convex block 10; The outer shape of the rotating groove 11 is arc-shaped. A limiting groove 13 is opened on one side of the fixing plate 5, and the limiting groove 13 is engaged with the convex block 10; A straight groove 12 is arranged on one side of the limiting groove 13, and the straight groove 12 is slidably connected with the convex block 10. The straight groove 12 is opened inside the fixing plate 5. The convex block 10 and the rotating groove 11 form a sliding structure, and the toggle lever 7 forms a rotating structure with the body 1 through a rotating shaft.

[0025] In specific implementation, when testing the temperature of the reflow furnace, the furnace temperature tester needs to be sent into the furnace body. When the closing cover 6 is separated from the body 1, the two sets of toggle rods 7 are toggled to rotate. When the protrusion 10 at one end of the toggle rod 7 rotates, it will slide in the rotating groove 11 inside the closing cover 6, and at the same time, it will cross the limiting groove 13 inside the fixing plate 5. When the protrusion 10 enters the straight groove 12, the closing cover 6 can be pulled up, and the protrusion 10 will slide in the straight groove 12 until it leaves the inside of the fixing plate 5, completing the separation of the closing cover 6 and the body 1. At this time, the electrical inside the body 1 can be tested. When the battery 3 is disassembled and assembled and the closing cover 6 is installed, the toggle rod 7 is toggled 90°, and the toggle rod 7 will pull the tension spring a8 to stretch it, and then the protrusion 10 at one end of the toggle rod 7 is docked with the straight groove 12 in the fixing plate 5. After the docking is completed, the toggle rod 7 can be released, and the tension spring a8 will be reset and pull the toggle rod 7 to rotate. At this time, the protrusion 10 at one end of the toggle rod 7 will enter the limiting groove 13 and engage with it, completing the connection between the body 1 and the body 1. In this way, the above operation can facilitate the disassembly and assembly of the battery 3 of the online monitoring device for the temperature curve of the reflow furnace.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 One end of the body 1 close to the joint a2 is fixedly connected to a slide rod 15, and a tension spring b14 is sleeved on the outer side of the slide rod 15; one end of the tension spring b14 is fixedly connected to a push plate 16, and the other end of the tension spring b14 is fixedly connected to the body 1. A through hole is opened inside the push plate 16, and the through hole is slidably connected to the slide rod 15. The slide rod 15 and the push plate 16 constitute a sliding structure, and the push plate 16, the body 1 and the tension spring b14 constitute an elastic telescopic structure.

[0027] During specific implementation, when the temperature of the reflow furnace is detected, the furnace temperature tester needs to be sent into the furnace body. When the furnace temperature tester is used, the thermocouple needs to be inserted into the joint a2, and then the thermocouple is fixed to the outside of the measured workpiece. When it is necessary to remove multiple sets of thermocouples inserted on the joint a2, the push plate 16 is pushed to move. The push plate 16 will slide on the outside of the slide bar 15 and pull the tension spring b14 to stretch it. When the push plate 16 contacts the thermocouple plugs connected to the joint a2, it can push the multiple sets of thermocouple plugs to move and disconnect them from the joint a2, completing the removal of the thermocouples. After removal, the push plate 16 can be released. At this time, the tension spring b14 will reset and pull the push plate 16 to move, so that the push plate 16 is also reset. In this way, the above operation can facilitate the centralized removal of the thermocouples connected to the online monitoring device of the reflow furnace temperature curve.

[0028] In summary: When using the online monitoring device for the reflow oven temperature curve, first insert the thermocouple into the connector a2 at one end of the body 1, then fix the thermocouple to the workpiece, and then send the workpiece and the body 1 into the reflow oven. The thermocouple will convert the temperature signal into a thermoelectromotive force signal and transmit the signal to the outside through the body 1 to achieve the online monitoring of the reflow oven temperature curve. After the test is completed, the body 1 can be taken out, and the wire can be inserted into the connector b4 and connected to the computer to download and save the temperature curve data. This is the feature of the online monitoring device for the reflow oven temperature curve.
