[0034] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0035] The present invention provides a flat enameled wire paint removal, tin lining and glue dispensing device, comprising an upper cover plate 1, a lower cover plate 2, an adsorption component and a tray 8.

[0036] like Figure 1As shown, the upper surface of the lower cover plate 2 is provided with more than two positioning grooves for placing flat enameled wires; the upper cover plate 1 and the lower cover plate 2 are rotatably connected on the same side by a rotating shaft, and an adsorption component is provided on the other side of the upper cover plate 1 and the lower cover plate 2, so that the upper cover plate 1 is fixed on the upper surface of the lower cover plate 2 to form a clamping device to achieve the clamping of the flat enameled wire; the clamping device is a rectangular parallelepiped, and the width and height are equal; the length is consistent with the tinning furnace, which is convenient for tinning. The width is determined according to the outer diameter of each flat enameled wire, and the height is determined according to the thickness of the flat enameled wire. The aspect ratio is between 8:1 and 9:1. The clamping device is a clamping and fixing device that directly contacts the flat enameled wire, and the material is synthetic stone.

[0037] Specifically, Figure 2 As shown, the positioning groove is an annular positioning groove 6, with a protrusion in the middle. The annular positioning groove 6 is connected to one of the side edges of the lower cover plate 2, serving as a projection groove for the flat enameled wire, and the side edge is perpendicular to the axis direction of the rotating shaft. The length of the flat enameled wire extending out of the clamping device is not more than 1 cm. In this embodiment, seven annular positioning grooves 6 are provided on the upper surface of the lower cover plate 2. The flat enameled wires are placed in the positioning grooves one by one, and seven products can be processed at the same time.

[0038] The lower cover plate 2 is L-shaped, the upper surface of the horizontal part 4 is used to set the positioning groove, the vertical part 3 is used to abut against the side of the upper cover plate 1, and after the upper cover plate 1 is adsorbed onto the upper surface of the horizontal part 4, the upper end surface of the vertical part 3 is flush with the upper surface of the upper cover plate 1; the lower cover plate 2 is provided with clamping parts 5 at both ends of the side opposite to the side where the vertical part 3 is located, one of the clamping parts 5 cooperates with the vertical part 3 to install the rotating shaft, and the other clamping part 5 cooperates with the vertical part 3 to limit the upper cover plate 1; the side where the clamping part 5 is located is the side connected to the annular positioning groove 6. Figure 3 As shown, notches are provided at both ends of the upper cover plate 1 to avoid the clamping portion 5.

[0039] Preferably, both the upper cover plate 1 and the lower cover plate 2 are provided with weight-reducing holes 7, which are used to reduce the weight of the device and improve the reliability of the vacuum nozzle adsorption process of the fully automatic tinning machine. In this embodiment, both the upper cover plate 1 and the lower cover plate 2 are provided with six through holes, and other numbers can also be provided, and the positions of the through holes of the upper cover plate 1 and the lower cover plate 2 may not correspond.

[0040] The adsorption components are magnets, which are respectively embedded in the magnet mounting holes 10 on the upper cover plate 1 and the lower cover plate 2 to help quick clamping and fixing.

[0041] The size of tray 8 is designed according to the preparation area of ​​the fully automatic tinning machine. Its external dimensions are consistent with the feeding platform of the fully automatic tinning machine equipment. It can be used as an ordinary tray during manual operation. Figure 4As shown, the tray 8 adopts a partially hollowed-out design, and a plurality of long holes are provided on the tray 8, and a slot 9 for engaging the clamping device is provided in the long holes. The clamping device is overlapped on the slot 9, and the width of the long hole is consistent with the width of the clamping device. Since the width and height of the clamping device are equal, while ensuring stable transportation of products, the clamping device can be stably lifted in all four placement states. Preferably, two extensions are provided on the long side of the long hole as support points to improve stability, and the extensions extend to the opposite long side and are located at the same level as the slot 9.

[0042] The tray 8 and the clamping device can cooperate to realize three production conditions, namely, paint removal, tinning and glue dispensing. Paint removal is a process of removing the paint from the surface of the enameled wire. Commonly used paint removal methods include physical paint removal and chemical paint removal. The present device can be suitable for high-temperature physical paint removal, and can also be suitable for chemical paint removal. The present device can depaint seven flat enameled wire products at a time, and can be painted manually or with a laser paint removal machine; tinning is a process of surface tinning. The present device can depaint seven flat enameled wire products at a time, and can be painted manually or with a fully automatic tinning machine with a vacuum nozzle; glue dispensing and fixing is a process of using an adhesive to bond the flat enameled wire and then clamping and fixing it. The present device can realize the glue dispensing of seven flat enameled wire products at a time and clamping and fixing them. Manual glue dispensing can be used, and it can also be used with a programmed fully automatic glue dispensing machine. Figure 5 As shown, the four side surfaces of the clamping device are defined as surface a, surface b, surface c, and surface d, wherein surface a is parallel to surface c, surface b is parallel to surface d, surface a is the upper surface of the upper cover plate 1, surface b is the outer surface of the clamping portion 5 of the lower cover plate 2, and surface d is the outer surface of the vertical portion 3 of the lower cover plate 2.

[0043] The specific steps of paint removal, tin lining and dispensing are as follows:

[0044] Step 1, such as Figure 6 As shown, the clamping device is placed with its surface a facing upwards in the long hole of the tray 8 and is limited on the card slot 9, and a laser paint removal device is used for automatic batch paint removal or manual paint removal;

[0045] Step 2, such as Figure 7 As shown, the clamping device is placed with its d side facing upwards in the long hole of the tray 8 and limited on the card slot 9, and batch automatic tinning or manual batch tinning is performed using a fully automatic tinning equipment with a vacuum nozzle;

[0046] Step three, such as Figure 8 As shown, the clamping device is placed with its b side facing upward in the long hole of the tray 8 and limited on the card slot 9, and a fully automatic dispensing machine is used to perform batch dispensing or manual dispensing of the flat enameled wire.

[0047] It can be seen that the device only needs to clamp the flat enameled wire once, and realize the three processes of paint removal, tinning and glue dispensing at the same time, and can process seven products at the same time for batch processing, avoiding repeated clamping of products, and improving actual production efficiency.

[0048] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. 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.
