[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a circuit board solder separation device, including a fixed base 1. The top of the fixed base 1 is elastically connected to a movable frame 3 via a return spring 2. The movable frame 3 is slidably connected to the top of the fixed base 1. Heated liquid is placed inside the movable frame 3. During the sliding process of the movable frame 3, the return spring 2 is squeezed, causing the return spring 2 to deform. During the reset, the rebound of the return spring 2 drives the movable frame 3 to slide and reset. A gear 6 is rotatably connected to the bottom of the movable frame 3. A rotating rod 8 is fixedly connected to the top of the gear 6. The movable frame 3 drives the gear 6 to slide inside the fixed base 1. The rotating rod 8 passes through the movable frame 3 and extends into the interior of the separation frame 10. The outer surface of the rotating rod 8 is rotatably and sealingly connected to the movable frame 3. A sealing layer is provided on the outer surface of the movable frame 3 through the rotating rod 8. The sealing layer improves the sealing performance between the rotating rod 8 and the movable frame 3 during the rotation process.

[0033] Furthermore, a servo motor 4 is fixedly connected to the top of the fixed base 1, and a push mechanism 5 is connected to the output end of the servo motor 4. A rack 7 is provided on the inner side wall of the fixed base 1, and a limit groove is opened inside the fixed base 1. The rack 7 is set in the limit groove, and the outer surface of the gear 6 meshes with the rack 7. The rack 7 causes the gear 6 to rotate during movement. The rotating gear 6 drives the rotating rod 8 to rotate. A separation frame 10 is provided inside the moving frame 3. The separation frame 10 is used to place the circuit board. A connecting component 9 is provided inside the rotating rod 8, and a stirring rod 11 is provided on the side wall of the rotating rod 8. The stirring rod 11 is rotatably connected inside the separation frame 10. The rotating rod 8 drives the stirring rod 11 to rotate inside the separation frame 10 during rotation, which satisfies the effect of stirring the stacked circuit boards.

[0034] Reference Figures 1-3 The pushing mechanism 5 includes a turntable 51. The bottom of the turntable 51 is fixedly connected to the output end of the servo motor 4. The servo motor 4 drives the turntable 51 to rotate. A connecting rod 52 is hinged to the top of the turntable 51. The rotation of the turntable 51 drives the connecting rod 52 to move. A push rod 53 is hinged to the end of the connecting rod 52. The end of the push rod 53 is hinged to the side wall of the moving frame 3. The movement of the connecting rod 52 drives the push rod 53 to move, thereby pushing the moving frame 3 to slide on the top of the fixed base 1.

[0035] Reference Figures 4-5The connecting component 9 includes a connecting frame 91, which is inserted into the interior of the rotating rod 8. A connecting groove is formed on the inner side wall of the rotating rod 8, and the connecting frame 91 is inserted into the connecting groove. The side wall of the connecting frame 91 is fixedly connected to the side wall of the stirring rod 11, thus connecting the stirring rod 11 and the rotating rod 8. A push plate 92 is elastically connected to the inner side wall of the connecting frame 91 via a positioning spring 94. During the sliding process of the push plate 92, it compresses the positioning spring 94, causing the positioning spring 94 to deform. The rebound of 4 causes the push plate 92 to slide and reset. The push plate 92 is slidably connected inside the connecting frame 91. A slide rod is provided at the bottom of the push plate 92. The slide rod passes through and is slidably connected inside the connecting frame 91. Pushing the slide rod causes the push plate 92 to slide inside the connecting frame 91. A positioning block 93 is fixedly connected to the side wall of the push plate 92. The positioning block 93 passes through and is inserted into the rotating rod 8. The positioning block 93 is inserted into the rotating rod 8 to improve the stable connection between the stirring rod 11 and the rotating rod 8.

[0036] Working principle: In use, the circuit board to be separated from solder is placed inside the separation frame 10, and then the separation frame 10 is placed inside the moving frame 3. The sliding rod on the side wall of the push plate 92 is then pushed, causing the push plate 92 to compress the positioning spring 94, which in turn causes the positioning block 93 to enter the connecting frame 91. The connecting frame 91 is then inserted into the rotating rod 8. Releasing the push on the sliding rod causes the positioning spring 94 to spring back, which in turn inserts the positioning block 93 into the rotating rod 8, thus connecting the stirring rod 11 and the rotating rod 8. Simultaneously, the servo motor... The operation of 4 drives the turntable 51 to rotate. The rotation of the turntable 51 drives the connecting rod 52 and the push rod 53 to move. During the movement, the push rod 53 drives the moving frame 3 to slide after squeezing the reset spring 2 on the fixed base 1. The gear 6 meshes with the rack 7. The movement of the moving frame 3 drives the gear 6 to move, thereby generating rotation. The rotation of the gear 6 drives the rotating rod 8 and the stirring rod 11 to rotate. During the rotation, the stirring rod 11 stirs the circuit board inside the separation frame 10, improving the efficiency of the circuit board solder separation.

[0037] When the circuit board solder separation is completed and the separation frame 10 needs to be removed, and when the stirring rod 11 needs to be disassembled and replaced after long-term use, the sliding rod drives the push plate 92 to squeeze the positioning spring 94 and then drive the positioning block 93 into the interior of the connecting frame 91. Then the connecting frame 91 is pulled out from the interior of the rotating rod 8, which satisfies the effect of disassembling and replacing the stirring rod 11.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
