When the scraping device 9 is about to contact the right inner wall of the heating chamber 1001, the propulsion device 8 will also drive the up and down moving parts of the displacement device 7 to work, so that the scraping device 9 moves upward, so that the impurities on the surface of the tin paste in the heating chamber 1001 are adhered to the scraping device 9, thereby completing a scraping of the surface of the tin paste in the heating chamber 1001.

[0035] Example 2

The second moving pair 73 is provided with a first elastic member 74, and the first elastic member 74 is a straight spring.

[0037] When the above embodiment is in operation, when the propulsion device 8 moves left and right, the propulsion device 8 will drive the movable plate 72 to move left and right through the first movable pair 71, thereby driving the scraping device 9 to move left and right. When the scraping device 9 is about to contact the inner wall of the heating chamber 1001, the propulsion device 8 will drive the scraping device 9 to move upward through the second movable pair 73. When the propulsion device 8 runs in the reverse direction, the propulsion device 8 will cause the scraping device 9 to move downward through the second movable pair 73 and the first elastic member 74 for reset.

[0038] like Figure 7 As shown, the propulsion device 8 includes a first electric slide rail 81, the middle part of the mounting frame 6 is connected to the first electric slide rail 81 by bolts, the moving part of the first electric slide rail 81 is connected to a moving frame 82 by bolts, the left and right sides of the moving frame 82 are connected to L-shaped frames 83 by bolts, the inner side of the L-shaped frame 83 is rotatably connected to a contact wheel 84, the contact wheel 84 cooperates with the scraping device 9, the inner rear side of the L-shaped frame 83 is connected to a second elastic member 85 by bolts, the second elastic member 85 is a straight spring, the inner side of the second elastic member 85 is connected to a connecting frame 86 by bolts, and the connecting frame 86 is connected to the moving plate 72.

[0039] When the above embodiment is in operation, after the start button is triggered by the control box 13, the first electric slide rail 81 will first run from left to right, thereby driving the movable frame 82 to move to the right, and the movable frame 82 will drive the contact wheel 84 to move to the right, and the L-shaped frame 83 will drive the connecting frame 86 and the movable plate 72 to move to the right through the second elastic member 85, thereby driving the scraping device 9 to move to the right. When the scraping device 9 is about to contact the right inner wall of the heating chamber 1001, the moving part of the first moving pair 71 has reached its own right end and will not continue to move to the right, and will not cause the scraping device 9 to continue to move to the right. At this time, the moving part of the first electric slide rail 81 continues to move to the right, which will cause the movable frame 82 to move to the right through the force of the second elastic member 85. When the contact wheel 84 does not cooperate with the scraping device 9, the scraping device 9 enters the heating chamber 1001 again, and the moving part of the first moving pair 71 will also begin to move to the left driven by the connecting frame 86.

[0040] like Figure 8As shown, the scraping device 9 includes a U-shaped frame 91, the front side of the moving part of the second moving pair 73 is connected to the U-shaped frame 91 by bolts, a V-shaped frame 92 is connected between the U-shaped frames 91 by bolts, the V-shaped frame 92 cooperates with the contact wheel 84, the front side of the U-shaped frame 91 is connected to an extension frame 93 by bolts, and a scraping plate 94 is installed on the lower side of the extension frame 93 by bolt connection.

[0041] When the above embodiment is in operation, when the movable plate 72 moves left and right, the movable plate 72 will drive the U-shaped frame 91, the V-shaped frame 92, the extension frame 93 and the scraper plate 94 to move left and right to remove impurities from the tin paste in the heating chamber 1001. When the scraper plate 94 is about to contact the inner wall of the heating chamber 1001, the movable part of the first movable pair 71 is at its own end. At this time, the scraper plate 94 will stay in this vertical position, and the contact wheel 84 will begin to contact the V-shaped frame 92, thereby driving the V-shaped frame 92 to move upward. The V-shaped frame 92 will drive the U-shaped frame 91 to move upward through the second movable pair 73, thereby driving the scraper plate 94 to move upward and away from the heating chamber 1001; when the contact wheel 84 moves away from the V-shaped frame 92, the V-shaped frame 92 will move downward to reset, thereby driving the scraper plate 94 to move downward to reset.

[0042] like Fig. 9 and Fig.10 As shown, it also includes a slag removal device 10, which includes a fixed frame 101. The slag removal device 10 is arranged between the support rod 2 and the extension frame 93, and the slag removal device 10 is used to remove slag from the scraping plate 94. The upper periphery of the support rod 2 is connected to the fixed frame 101 by bolts, and the inner side of the fixed frame 101 is rotatably connected to the rotating shaft 102, and the rotating shaft 102 is connected to a rotating frame 103 by bolts. A third elastic member 104 is connected between the rotating frame 103 and the adjacent fixed frame 101, and the third elastic member 104 is a torsion spring. A slag removal bucket 105 is connected to the lower side of the rotating frame 103 by bolts, and the slag removal bucket 105 cooperates with the scraping plate 94. The inner side of the rotating frame 103 is connected to a contact rod 106 by bolts, and the upper side of the extension frame 93 is connected to a contact frame 107 by bolts, and the contact frame 107 cooperates with the contact rod 106.

[0043] When the above embodiment is in operation, when the extension frame 93 and the scraper plate 94 move, the extension frame 93 will drive the contact frame 107 to move to the bottom of a contact rod 106 for contact. When the scraper plate 94 moves upward, the upward movement of the scraper plate 94 will drive the contact frame 107 to move upward, thereby driving the contact rod 106 to drive the rotating frame 103 to rotate through the rotating shaft 102, thereby driving the slag bucket 105 to rotate. During the rotation of the slag bucket 105, the scraper plate 94 will be surrounded. The scraper bucket 105 will remove impurities adhered to the surface of the scraper plate 94 in the process of surrounding it; when the scraper plate 94 moves downward, the contact frame 107 will also move downward. At this time, the third elastic member 104 will drive the rotating frame 103 and the contact rod 106 to reset, thereby driving the slag bucket 105 to reset.

[0044] like Fig.11 As shown, it also includes a covering device 11, which includes a second electric slide rail 111. The covering device 11 is arranged between the support frames 3, and the covering device 11 is used to cover the heating chamber 1001 and quickly dip the pine oil.

The up and down movement of the second electric slide 111 will drive the oiling component 12 and the lifting frame 113 to move up and down, so as to facilitate the processing of the heating chamber 1001; when the activation button is pressed, when the handheld circuit board is inserted into the oiling component 12 to loosen the oil, the oiling component 12 will be triggered, so that the second electric slide 111 is in a standby state. When the handheld circuit board is extended out of the position of the oiling component 12, the oiling component 12 will control the second electric slide 111 to start from the standby state through the control box 13, so that the moving part of the second electric slide 111 drives the lifting frame 113 and the oiling component 12 to When the activation button is pressed, the dwell time of the second electric slide rail 111 after it moves upward can be set through the digital buttons on the control box 13, so as to cope with the time required for the dip soldering of different types of circuit boards. After the second electric slide rail 111 moves upward and reaches the set dwell time, the control box 13 will control the second electric slide rail 111 to automatically move downward for reset, thereby driving the lifting frame 113 and the oiling assembly 12 to move downward for reset. This can prevent the heating chamber 1001 from being contaminated by external impurities or dust during the process of taking and placing the circuit boards, and at the same time enable manual labor to quickly dip in pine oil when performing dip soldering of the circuit boards, thus avoiding manual forgetfulness, and also reducing the path required for manual transfer of the circuit boards, thereby improving the auxiliary capacity.
