[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 2-Figure 5The present invention provides a technical solution: a tin furnace structure 100 for selective wave soldering equipment, comprising a tin furnace transfer cart 1, a cart positioning mechanism 2 installed on the selective wave soldering equipment 5 for positioning the tin furnace transfer cart 1, a detection component 3 for detecting whether the tin furnace transfer cart 1 is inserted into the cart positioning mechanism 2, and a control component 4 for disassembling the tin furnace 52 according to the detection result of the detection component 3. The tin furnace transfer cart 1 comprises a cart frame 11, at least one cart tin furnace platform 12 installed on the cart frame 11, one end of the cart frame 11 is provided with a positioning component 13 for positioning with the cart positioning mechanism 2, the cart positioning mechanism 2 specifically comprises a guide rod assembly 21, and a plurality of positioning blocks 131 in the positioning assembly 13 are inserted into the gaps between the guide rods to realize the installation of the tin furnace transfer cart 1 on the cart positioning mechanism 2 of the selective wave soldering equipment 5.

[0037] Specifically, the tin furnace transfer cart 1 is used to transfer the tin furnace 52 to the welding platform 51 of the selective wave soldering equipment 5 or to transfer from the welding platform 51 of the selective wave soldering equipment 5 to the tin furnace 52. It can be understood that the design of the tin furnace transfer cart 1 in the present application is to enable the tin furnace 52 to be disassembled or installed more easily, thereby eliminating the cumbersome problem of disassembling or installing the tin furnace 52 directly on the selective wave soldering equipment 5 in the past.

[0038] The specific trolley frame 11 of the tin furnace transfer trolley 1 is used to realize the transportation of the tin furnace 52. As shown in the figure, the trolley frame 11 is formed by overlapping two parallel, right-angled frames, one side of which is parallel to the ground and is equipped with a conveying wheel, such as a fixed wheel or a heavy-loaded universal wheel to realize the movement of the trolley frame 11. The other side is perpendicular to the ground and is provided with a handrail for pushing the trolley frame 11.

[0039] At least one trolley tin furnace platform 12 is installed on the trolley frame 11. Specifically, a support frame for carrying the trolley tin furnace platform 12 is also provided on one side of the two right-angled frames perpendicular to the ground, and one or more trolley tin furnace platforms 12 can be installed on the support frame.

[0040] Furthermore, the cart tin furnace platform 12 specifically includes: two parallel tin furnace support plates 121 and 122 for carrying the tin furnace 52; one end of the tin furnace support plate 121 and 122 is connected to the cart frame 11; the other ends of the tin furnace support plate 121 and 122 are respectively provided with tin furnace side blocks 123; the tin furnace support plate 121 and 122 are respectively provided with tin furnace guide columns 124 and 125 for positioning, and the tin furnace guide columns 124 and 125 are diagonally arranged.

[0041] Specifically, the tin furnace support plate 1 121 and the tin furnace support plate 2 122 can be directly connected to the support frame of the cart frame 11, or can be connected to the support frame of the cart frame 11 through a connecting plate. The tin furnace side block 123 is used to limit the movement of the tin furnace 52 along the long side direction of the support plate 2. The tin furnace guide column 1 124 is arranged on the tin furnace support plate 1 121, and the tin furnace guide column 2 125 is arranged on the tin furnace support plate 2 122, which are used to further limit the position of the tin furnace. The diagonal arrangement of the tin furnace guide column 1 124 and the tin furnace guide column 2 125 can more stably ensure that the tin furnace 52 is fixed to the tin furnace support plate 1 121 and the tin furnace support plate 2 122.

[0042] In addition, considering the problem that the tin furnace transfer cart 1 will carry the heated tin furnace 52 for transfer transportation, the tin furnace guide column 1 124 and the tin furnace guide column 2 125 are also respectively provided with locking holes 1251, which are used to lock the tin furnace 52 to the tin furnace support plate 1 121 and the tin furnace support plate 2 122 by butterfly screws after the tin furnace 52 is installed on the tin furnace guide column 124 and the tin furnace guide column 2 125 of the tin furnace support plate 121 and the tin furnace support plate 2 122.

[0043] Specifically, the tin furnace 52 is fixed to the tin furnace transfer cart 1 by locking the butterfly screws to the locking holes 1251 of the tin furnace guide column 1 124 and the tin furnace guide column 2 125 .

[0044] Furthermore, the tin furnace transfer cart 1 also includes: a UPS power supply 14 arranged on the cart frame 11, which is used to electrically heat the tin furnace 52 carried by the cart tin furnace platform 12.

[0045] It is conceivable that when the selective wave soldering equipment 5 needs to replace the tin furnace 52, the UPS power supply 14 can be used to preheat the tin furnace 52 carrying tin on the tin furnace platform 12 on the tin furnace transfer cart 1, thereby saving the previous need to first install the tin furnace 52 without tin on the selective wave soldering equipment 5, and then install screws, plugs, etc., and finally put the solid tin into the tin furnace 52 for tinning, which requires a long waiting time and affects the production capacity.

[0046] One end of the cart frame 11 is provided with a positioning assembly 13 for achieving positioning with the cart positioning mechanism 2. Specifically, positioning blocks 131 are respectively provided on one end of the two right-angled frames parallel to the ground to achieve positioning of the cart positioning mechanism 2 inserted into the selective wave soldering equipment 5.

[0047] Furthermore, an adjustable shock-absorbing pad is also provided on the cart frame 11. It is understandable that when the tin furnace transfer cart 1 is inserted through the gap between the guide rods in the guide rod assembly 21 of the cart positioning mechanism 2, if the insertion is too fast, the tin furnace transfer cart 1 may hit the guide rods, so an adjustable shock-absorbing pad is provided to effectively reduce the impact of the cart.

[0048] The trolley positioning mechanism 2 is installed in the wave soldering equipment, and is used for positioning the trolley 1 in the tin furnace when the tin furnace 52 needs to be disassembled or installed. As shown in the accompanying drawings, the trolley positioning mechanism is installed at the bottom of the selective wave soldering equipment. The trolley positioning mechanism 2 includes a guide rod assembly 21, and the guide rod assembly 21 at least includes a guide rod 1 211 and a guide rod 2 212 separated by a preset distance. It can be understood that the guide rod assembly 21 is mainly used for inserting the positioning blocks 131 on the two right-angled shelves. Obviously, the guide rod assembly 21 can only be used for positioning one of the positioning blocks 131 of the two right-angled shelves by the guide rod 1 211 and the guide rod 2 212, and the guide rod 3 and the guide rod 4 can also be set to position the other, that is, the guide rod 1 211, the guide rod 2 212 and the guide rod 3 and the guide rod 4 respectively position the two positioning blocks 131 of the two right-angled shelves.

[0049] Furthermore, the ends of the two opposite end surfaces of the guide rod 1 211 and the guide rod 2 212 for inserting the cart frame 11 are chamfered to facilitate the insertion of the cart frame 11. It should be understood that the chamfers are provided so that the ends of the two opposite end surfaces of the guide rod 1 211 and the guide rod 2 212 form an outer eight-shaped shape, thereby more conveniently realizing the insertion of the right-angled frame of the cart frame 11.

[0050] A detection component 3 is used to detect whether the tin furnace transfer trolley 1 is inserted into the trolley positioning mechanism 2. It can be understood that the setting of the detection component 3 can enable the tin furnace transfer trolley 1 to locate whether it is inserted into place after being inserted into the trolley positioning structure.

[0051] Furthermore, a plurality of balls 2121 are installed on the opposite end surfaces of the guide rod 1 211 and the guide rod 2 212 to facilitate the insertion of the cart frame 11 .

[0052] Specifically, by installing the ball bearings 2121 on the two opposite end surfaces of the guide rod 1 211 and the guide rod 212, the tin furnace transfer cart 1 can enter more conveniently.

[0053] Furthermore, the detection component 3 specifically includes: a safety switch 31 respectively arranged on the cart frame 11 and the guide rod 211; a cart positioning detection cylinder 32 installed on the guide rod 211; the cart positioning detection cylinder 32 at least includes a cylinder 52 and a positioning column 34 connected to the cylinder 52, and the positioning block 131 is provided with a positioning hole 1311 for inserting the positioning column 34.

[0054] Specifically, when the tin furnace transfer trolley 1 is pushed to the gap between the guide rods of the trolley positioning mechanism 2 and is in place, the safety switch 31 receives a signal and then the positioning column 34 of the trolley positioning detection cylinder 32 extends and is inserted into the positioning hole 1311 of the positioning column 34 to achieve positioning.

[0055] It should be noted that only when the safety positioning switches on the cart frame 11 and the guide rod 211 receive signals, the positioning column 34 of the cart positioning detection cylinder 32 will be extended, thereby improving the safety of the tin furnace transfer cart 1.

[0056] It should also be noted that the positioning column 34 connected to the cylinder 52 can be a single one and then inserted into the positioning hole 1311 on the positioning block 131. It can also be that there are several positioning heads on the positioning column 34, and there are positioning holes 1311 corresponding to the several positioning heads on the positioning block 131. Of course, the positioning head can also be conical, and the conical positioning head corresponds to the expanded positioning hole 1311. It can be understood that the positioning of multiple positioning heads can more stably realize the fixing of the tin furnace transfer trolley 1 by the trolley positioning mechanism 2.

[0057] It should also be noted that the detection component 3 also includes a detection component 3 for detecting the tin content in the tin furnace 52, so as to determine whether the tin furnace 52 needs to be replaced.

[0058] A control component 4 is used to disassemble the tin furnace 52 according to the detection result of the detection component 3. Specifically, after receiving the detection signal of the detection component 3, the control component 4 determines the disassembly of the tin furnace 52. For example, when the control component 4 receives a signal from the detection component 3 that the tin furnace 52 has a low content and needs to be replaced, the control component 4 disassembles the tin furnace 52 after receiving the signal. It is understandable that after the tin furnace 52 is disassembled, the tin furnace 52 filled with tin needs to be installed. In the present application, when the control component 4 receives the signal that the tin content in the tin furnace 52 is low, the tin furnace 52 filled with solid tin and installed on the tin furnace transfer cart 1 is preheated. After the tin furnace 52 with a low tin content is disassembled, the tin furnace 52 in liquid state after preheating is installed on the cart positioning mechanism 2 through the tin furnace transfer cart 1, and it is replaced by the welding platform 51 of the selective wave soldering equipment 5.

[0059] It can be seen that compared with the previous disassembly of the tin furnace 52, the present application does not need to remove the tin first, turn off the heating of the tin furnace 52, unplug the plug of the tin furnace 52, and other cumbersome, dangerous, and inefficient disassembly and assembly. Compared with the previous installation of the tin furnace 52, the present application does not need to heat the solid tin to liquid tin after the cumbersome installation of the tin furnace 52, which requires a long time to wait and affects the installation of production capacity.

[0060] like Figure 6 As shown, based on a tin furnace structure 100 for selective wave soldering equipment provided in an embodiment of the present application, the present application also provides a disassembly method based on the structure, comprising the following steps:

[0061] S100: The control component 4 issues a disassembly instruction for the tin furnace 52;

[0062] S110: Push the tin furnace transfer trolley 1 to insert into the trolley positioning mechanism 2. When the safety switch 31 of the detection component 3 senses that the tin furnace transfer trolley 1 is inserted into the trolley positioning mechanism 2, the trolley positioning detection cylinder 32 extends the positioning column 34 and inserts it into the positioning hole 1311;

[0063] S120: The selective wave soldering equipment 5 descends to move the tin furnace 52 to the cart tin furnace platform 12, the cart positioning detection cylinder 32 retracts, the tin furnace transfer cart 1 exits the cart positioning mechanism 2, and the tin furnace 52 is disassembled.

[0064] Specifically, before the control component 4 issues a disassembly instruction, the detection component 3 sends a signal indicating that the tin content in the tin furnace 52 in use is low to the control component 4. After receiving the signal, the control component 4 issues a disassembly instruction, and the welding platform 51 of the selective wave soldering equipment 5 moves to the waiting position. The user inserts the tin furnace transfer cart 1 into the cart positioning mechanism 2, and the cart positioning detection cylinder 32 extends and inserts into the positioning hole 1311 of the positioning block 131 to achieve the positioning of the tin furnace transfer cart 1. The welding platform 51 carries the tin content with low content and moves all the way to the top of the tin furnace transfer cart 1. The personnel unplug the plug of the tin furnace 52, loosen the mounting nut of the tin furnace 52, and the welding platform 51 starts to descend, and the tin furnace 52 is placed on the cart tin furnace platform 12. The cart tin furnace platform 12 is provided with a tin furnace guide column, and the tin furnace 52 is chamfered along the tin furnace guide column and inserted into the cart tin furnace platform 12. When it reaches the bottom, the tin furnace 52 is placed and has been positioned. The welding platform 51 returns to the waiting position, the cart positioning detection cylinder 32 retracts, and the equipment prompts the personnel to take out the tin furnace transfer cart 1. The personnel take out the tin furnace transfer cart 1, and the tin furnace 52 is disassembled.

[0065] like Figure 7 As shown, based on a tin furnace structure 100 for a selective wave soldering device provided in an embodiment of the present application, the present application also provides an installation method of the tin furnace structure 100 for a selective wave soldering device, comprising the following steps:

[0066] S200: preheating the tin furnace 52 placed on the tin furnace transfer cart 1 through the UPS power supply 14 of the cart frame 11, so as to facilitate the electrothermal tinization of the tin in the tin furnace 52;

[0067] S210: Obtaining the installation instruction of the tin furnace 52 issued by the control component 4;

[0068] S220: Push the tin furnace transfer trolley 1 to insert into the trolley positioning mechanism 2. When the safety switch 31 of the detection component 3 senses that the tin furnace transfer trolley 1 is inserted into the trolley positioning mechanism 2, the trolley positioning detection cylinder 32 extends the positioning column 34 and inserts it into the positioning hole 1311;

[0069] S230: The welding platform 51 of the selective wave soldering equipment 5 rises to connect the tin furnace 52 of the tin furnace transfer trolley 1 on the tin furnace platform 12 to the welding platform 51, the trolley positioning detection cylinder 32 retracts, the tin furnace transfer trolley 1 exits the trolley positioning mechanism 2, and the installation of the tin furnace 52 is completed.

[0070] Specifically, before the control component 4 issues the installation instruction, the control instruction first receives a signal indicating that the tin content in the tin furnace 52 is low. At the time of receiving the signal or a period of time later, the control component 4 issues an instruction to preheat the tin furnace 52 to be installed, and the personnel preheat the tin furnace 52 placed on the tin furnace transfer cart 1 through the UPS power supply 14 of the cart frame 11, so as to facilitate the electrothermal tinization of the tin in the tin furnace 52. After the tin furnace 52 with a low content is disassembled, the control component 4 issues an instruction to install the tin furnace 52, and the welding platform 51 of the selective wave soldering equipment 5 moves to the waiting position. The user inserts the tin furnace transfer cart 1 into the cart positioning mechanism 2, and the cart positioning detection cylinder 32 extends and inserts into the positioning hole 1311 of the positioning block 131 to realize the positioning of the tin furnace transfer cart 1. The welding platform 51 moves to the bottom of the cart tin furnace platform 12 and starts to rise, connecting the tin furnace 52 of the tin furnace transfer cart 1 to the welding platform 51. The personnel install the tin furnace 52 installation nut, plug in the tin furnace 52 plug, and the welding platform 51 returns to the waiting position. The cart positioning detection cylinder 32 retracts, and the equipment prompts the personnel to take out the tin furnace transfer cart 1. The personnel take out the tin furnace transfer cart 1, and the installation of the tin furnace 52 is completed.

[0071] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
