[0037] Specifically, the solder paste tray 2 is used to contain solder paste, and the solder paste tray 2 is located above the base 1 .

[0038] like Figure 3 , Figure 4 and Figure 5 As shown, the mobile module 3 is arranged on one side of the base 1 and extends horizontally along one side of the base 1. The mobile module 3 includes a connecting plate 31, a first transmission wheel 32, a second transmission wheel 33, a transmission belt 34, a transmission block 35, a motor 36 and a vertical support rod 37; the connecting plate 31 is connected to one side of the base 1, the first transmission wheel 32 and the second transmission wheel 33 are respectively connected to the connecting plate 31, the first transmission wheel 32 and the second transmission wheel 33 are located at the same horizontal height and are arranged at intervals, and the transmission belts 34 are respectively connected to the first transmission wheel 32 The motor 36 is arranged on the connecting plate 31, and the rotating shaft of the motor 36 is connected to the first transmission wheel 32. The middle part of the transmission block 35 is provided with a through slot adapted to the transmission belt 34, and the transmission belt 34 passes through the through slot and is fixedly connected to the transmission block 35. When the motor 36 is started, the first transmission wheel 32 rotates with the rotating shaft of the motor 36, and the transmission belt 34 rotates with the first transmission wheel 32, and drives the second transmission wheel 33 to rotate; the transmission block 35 also moves with the transmission belt 34. The vertical support rod 37 is arranged vertically, and its downward end is connected to the transmission block 35 and moves with the transmission block 35. The upward end of the vertical support rod 37 is connected to the buffer module 5 through the support assembly 4.

[0039] As a further improvement of the present embodiment, in order to make the support rod move smoothly, the mobile module 3 is further provided with a second slide rail 38 and a second slider 39 that cooperate with each other. The second slide rail 38 is connected to the connecting plate 31, and the second slide rail 38 is arranged horizontally and is consistent with the extension direction of the connecting plate 31; the second slider 39 is engaged with the second slide rail 38 and can move along the axial direction of the second slide rail 38, and the second slider 39 is connected to the vertical support rod 37. When the vertical support rod 37 moves with the transmission block 35, it drives the second slider 39 to move along the second slide rail 38. The second slider 39 can support the vertical support rod 37 to prevent the downward force of the vertical support rod 37 from acting entirely on the transmission belt 34. In order to make the vertical support rod 37 move more smoothly, a second slide rail 38 can be provided on each of the upper and lower sides of the transmission belt 34, and a second slider 39 can be provided to connect with the vertical support rod 37.

[0040] The support assembly 4 includes a first support member 41 and a second support member 42. The first support member 41 is arranged horizontally and perpendicular to the first slide rail 52. One end of the first support member 41 is connected to the vertical support rod 37, and the other end of the first support member 41 is connected to the second support member 42. The first support member 41 extends from the vertical support rod 37 to above the solder paste tray 2, so as to make the second support member 42 located in the middle of the solder paste tray 2. The second support member 42 is a plate body, which extends in the vertical direction.

[0041] like Figure 2 As shown, the buffer module 5 includes a first slide rail 52 and a first slider 51 that cooperate with each other, and also includes a first stopper 53, a second stopper 54 and a column 55. Specifically, the first slide rail 52, the first stopper 53 and the second stopper 54 are all located on a side of the second support member 42 away from the vertical support rod 37; the first stopper 53 and the second stopper 54 are respectively arranged at the upper and lower ends of the second support member 42, the first stopper 53 is provided with a first through hole, the shaft body is passed through the first through hole, and is connected to the lifting module 6; the first slide rail 52 is located above the second support member 42, the first slide rail 52 extends in the vertical direction, and the first slider 51 is engaged with the first slide rail 52.

[0042] The lifting module 6 includes a first connecting member 61 and a cylinder 62. The first connecting member 61 includes an integrally formed vertical plate and a horizontal plate, wherein the vertical plate extends in the vertical direction and the horizontal plate is arranged horizontally; the vertical plate is located between the first limiting member 53 and the second limiting member 54, and the vertical plate is connected to the first slider 51. The first limiting member 53 and the second limiting member 54 are used to limit the up and down movement range of the first connecting member 61 and / or the first slider 51 to prevent the first slider 51 from being separated from the first slide rail 52. Specifically, the first connecting member 61 is connected to one end of the column 55, and the other end of the column 55 extends into the first through hole and is movably connected to the first limiting member 53. The cylinder body of the first cylinder 62 is connected to the horizontal plate, and the piston rod of the first cylinder 62 is connected to the scraper 7 through the second connecting member; the first cylinder 62 is arranged vertically.

[0043] The scraper 7 is arranged horizontally, and the extending direction of the scraper 7 is perpendicular to the axial direction of the second slide rail 38 .

[0044] This embodiment provides a solder paste scraping device. When working, the first cylinder 62 is first started to extend the piston rod to a suitable position, so that the scraper 7 is close to the solder paste tray 2, or the scraper 7 is in contact with the solder paste tray 2. Due to the buffer module 5, when there is a gap between the scraper 7 and the solder paste tray 2, the first slider 51 will slide downward due to gravity, so that the scraper 7 is in contact with the solder paste tray 2; if the piston rod is extended to a greater position so that the scraper 7 is squeezed with the solder paste tray 2, the slider will be pushed upward to slide upward, so that the scraper 7 is just in contact with the solder paste tray 2, avoiding the scraper 7 and the solder paste tray 2 from being squeezed and deformed. The motor 36 in the moving module 3 is started, and the scraper 7 moves along the direction of the second slide rail 38 to scrape the solder paste in the solder paste tray 2.

[0045] This embodiment provides a solder paste scraping device, which is provided with a buffer module 5 and a lifting module 6 flexibly connected to avoid the scraper 7 and the solder paste tray 2 from being squeezed and deformed, and the scraper 7 just abuts against the surface of the solder paste tray 2, which can effectively scrape the solder paste. The height of the solder paste is flush with the surface of the solder paste tray 2, and the surface flatness of the solder paste is good.
