Description

Technical Field

[0001] The present application relates to the technical field of reflow soldering furnaces, and in particular to a reflow soldering furnace stability detection device. Background Art

[0002] The reflow oven is one of the commonly used equipment in the electronics manufacturing industry, which is used to carry out the soldering process in surface mount technology. In production, electronic components are placed on the printed circuit board and then soldered through the reflow oven to ensure that they are firmly connected to the printed circuit board. The reflow oven achieves the soldering process by controlling the temperature curve. Generally, the reflow oven includes a preheating zone, a soldering zone, and a cooling zone. In the preheating zone, the printed circuit board and components are gradually heated to a predetermined temperature to activate the solder paste. Next, they enter the soldering zone, where the soldering point reaches the melting point and forms a connection. Finally, the printed circuit board passes through the cooling zone, and the temperature is gradually reduced to ensure that the soldering is fully solidified. The design and control of the reflow oven is crucial to ensure the quality of soldering, because the correct temperature curve can avoid soldering defects. It plays an important role in electronic manufacturing and helps produce high-quality electronic products.

[0003] The reflow oven sets several groups of temperature detection probes inside the box to detect whether the temperature inside the box changes in real time at multiple points, so as to avoid the phenomenon of scrapping parts due to insufficient welding if the temperature is too low.

[0004] When temperature detection is performed using a temperature detection probe, the service life of the temperature detection probe is reduced because the temperature detection probe is in a high temperature environment for a long time. The temperature detection probe is arranged on the inner wall of the box, so when the damaged temperature detection probe is disassembled and replaced, the outer shell of the box needs to be disassembled for replacement. This replacement method will increase the operator's time and energy. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The following is combined with Figure 1-4 The embodiments of the present application are described in further detail.

[0037] Combined with Figure 1-Figure 4 , an embodiment provided by the present application: a reflow oven stability detection device, the stability detection device comprising:

[0038] The reflow oven body 1 is convenient for fixing the upper structure;

[0039] A conveyor belt 2 is fixed to the groove in the center of the reflow oven body 1 through a rotating roller, and the conveyor belt 2 can continuously convey the electronic components to the designated working area;

[0040] The bottom of the heating box 3 is connected with the upper center of the reflow oven body 1 by bolts, and the heating box 3 is convenient for subsequent welding work by heating up the inside;

[0041] The driving motor 4 is connected with the central part of one end of the outer side of the heating box 3 by bolts at the bottom of the driving motor 4, so that the driving motor 4 can drive the output end on one side to rotate conveniently;

[0042] A first shaft 5, one end of which is connected to the output end of the driving motor 4, so as to drive the structure on the shaft to rotate synchronously; and the other end of the first shaft 5 is located at one side of the interior of the heating box 3;

[0043] A second shaft 6, one end of which is welded to the other side of the heating box 3, so that the structure on the shaft provides stability during rotation;

[0044] Sleeve 7, sleeve 7 is rotatably connected to one end of the second shaft 6, and the diameter of the hole inside the sleeve 7 is larger than the diameter of the second shaft 6. Sleeve 7 can provide mutual connection between structures to facilitate subsequent stable rotation;

[0045] A "U"-shaped fixing plate 8, both ends of which are respectively welded to the first shaft 5 and one end of the sleeve 7, which can improve stability during subsequent rotation;

[0046] The temperature detection probe 9 has its top end engaged and fixed with a groove reserved at the bottom of the "U"-shaped fixing plate 8, so as to facilitate real-time temperature detection.

[0047] A No. 1 "C"-shaped plate 10 is horizontally welded on both sides of the interior of the heating box body 3, and the groove on one side of the No. 1 "C"-shaped plate 10 can stabilize the internal structure for displacement; a No. 2 "C"-shaped plate 11 is slidably connected inside the groove on one side of the No. 1 "C"-shaped plate 10, and the groove on one side of the No. 2 "C"-shaped plate 11 can stabilize the internal structure for displacement.

[0048] A "T"-shaped plate 12 is slidably connected inside the groove of the second "C"-shaped plate 11, and the two groups of "T"-shaped plates 12 are mirror-set inside the heating box 3. After one side of the two groups of "T"-shaped plates 12 are fitted together, effective temperature retention is convenient.

[0049] A bidirectional motor 13 is horizontally bolted to the center of one side of the outside of the heating box 3, and the bidirectional motor 13 can easily drive the structures on the output ends on both sides to rotate; threaded screws 14 are horizontally connected to the output ends on both sides of the bidirectional motor 13, and when the threaded screws 14 rotate, they can easily drive the structure on the rod to move.

[0050] A connecting plate 15 is rotatably connected to the threaded screw 14, and the connecting plate 15 serves to connect the structures. The connecting plate 15 is in a "U" shape, and the other end of the connecting plate 15 is welded to the bottom of one side of the "T"-shaped plate 12, so that when the structure is displaced, it can drive the structure on one side to displace synchronously.

[0051] The implementation principle of a reflow oven stability detection device of the present application is:

[0052] First, the electronic components are placed on the conveyor mesh 2, and then transported to the interior of the heating box 3 through the conveyor mesh 2, and then the heating box 3 is heated to perform welding of the electronic components. When the heating box 3 is heated, a number of groups of temperature detection probes 9 can be used to detect the internal temperature of the heating box 3 in real time, thereby avoiding the phenomenon of scrapping of electronic components during welding.

[0053] Secondly, when the temperature detection probe 9 is damaged in a high temperature environment and needs to be disassembled and replaced, the bidirectional motor 13 is started. The bidirectional motor 13 drives the threaded screw 14 on the output ends on both sides to rotate. When the threaded screw 14 rotates, the connecting plate 15 on the driving rod is displaced. When the connecting plate 15 is displaced, the "T"-shaped plate 12 is displaced. When the "T"-shaped plate 12 is displaced, it drives the second "C"-shaped plate 11 to displace inside the first "C"-shaped plate 10. When one side of the two groups of "T"-shaped plates 12 are in contact with each other, the temperature of the heating box 3 can be effectively maintained.

[0054] Finally, start the drive motor 4, which drives the No. 1 shaft 5 on the output end to rotate. When the No. 1 shaft 5 rotates, the other end of the "U"-shaped fixing plate 8 on one side rotates stably on the No. 2 shaft 6 through the sleeve 7. At this time, the temperature detection probe 9 at the bottom of the "U"-shaped fixing plate 8 will rotate to the top of the "U"-shaped fixing plate 8, thereby facilitating the disassembly and replacement of the "U"-shaped fixing plate 8.

[0055] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
