Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The present invention provides a structure for a dual-head precision synchronous dispensing head mechanism as follows: Figure 1 as well as Figure 5 As shown, it includes a lifting module 1, which consists of a support plate 11, a Z-axis linear module 12, a slide block 13, and a precision displacement sensor 14. The Z-axis linear module 12 is mounted on the surface of the support plate 11, the slide block 13 is mounted on the sliding end of the Z-axis linear module 12, the precision displacement sensor 14 is mounted on the surface of the slide block 13, and a carrier frame 5 is fixed on the surface of the slide block 13.

[0020] During implementation, the slide block 13 is driven to move by the Z-axis linear module 12 on the surface of the support plate 11, and the displacement is sensed by the precision displacement sensor 14 during the movement.

[0021] Furthermore, such as Figure 2 , Figure 6 as well as Figure 7 As shown, a right dispensing assembly 2 is installed at one end of the surface of the carrier 5. The right dispensing assembly 2 is used to realize mobile dispensing operation. The right dispensing assembly 2 includes an X-axis lead screw module 21, an X-axis moving frame 22, a Y-axis lead screw module 23, a Y-axis moving frame 24, a right side mounting base 25, and a right side dispensing device 26. The X-axis lead screw module 21 is installed on the surface of the carrier 5, and an outer protective cover 211 is installed on the surface of the X-axis lead screw module 21. The X-axis moving frame 22 is installed on the nut block of the X-axis lead screw module 21. The Y-axis lead screw module 23 is installed at the bottom of the X-axis moving frame 22, and the Y-axis moving frame 24 is fixed on the nut block of the Y-axis lead screw module 23. The right side mounting base 25 is installed on the surface of the Y-axis moving frame 24, and the right side mounting base 25 and the X-axis moving frame 22 are slidably connected to each other through a slide rail slider. The right side dispensing device 26 is installed on the surface of the right side mounting base 25, and the right side dispensing device 26 is used to realize dispensing operation.

[0022] During implementation, the X-axis lead screw module 21 drives the X-axis moving frame 22 to move along the X-axis, and the Y-axis lead screw module 23 drives the right mounting base 25 to move along the Y-axis under the action of the Y-axis moving frame 24, so that the right dispensing device 26 on the surface of the right mounting base 25 moves synchronously to complete the dispensing work.

[0023] Furthermore, such as Figure 3 as well as Figure 8As shown, the other end of the surface of the carrier 5 is connected to the left dispensing assembly 3. The left dispensing assembly 3 is used to realize fixed dispensing work, and the left dispensing assembly 3, together with the right dispensing assembly 2, can realize dual-head synchronous dispensing work. The left dispensing assembly 3 is composed of a fixed frame 31, a Z-axis lead screw module 32, a mounting plate 33, a left mounting frame 34, and a left dispensing device 35. The fixed frame 31 is fixedly connected to the surface of the carrier 5. The Z-axis lead screw module 32 is mounted on the surface of the fixed frame 31, and the sliding end of the Z-axis lead screw module 32 is mounted with the mounting plate 33. The left mounting frame 34 is fixed on the surface of the mounting plate 33, and the left dispensing device 35 is mounted on the surface of the left mounting frame 34.

[0024] During implementation, the Z-axis lead screw module 32 on the surface of the fixed frame 31 drives the mounting plate 33 to move along the Z-axis. When the mounting plate 33 moves, it will drive the left dispensing device 35 on the surface of the left mounting frame 34 to complete the dispensing work.

[0025] Furthermore, such as Figure 4 as well as Figure 9 As shown, a visual positioning component 4 is mounted on the surface of the slide 13. The visual positioning component 4 is used for visual positioning when the right dispensing component 2 and the left dispensing component 3 are dispensing. The visual positioning component 4 includes a connecting plate 41, a CCD camera 42, a coaxial light source 43, and a backlight plate 44. The connecting plate 41 is mounted on the surface of the slide 13, and the CCD camera 42 is fixed on the surface of the connecting plate 41. The coaxial light source 43 is mounted on the surface of the carrier 5 through a bracket. The backlight plate 44 is mounted on the bracket of the coaxial light source 43 through a fixing piece, and the center lines of the backlight plate 44, the coaxial light source 43, and the CCD camera 42 coincide.

[0026] During implementation, the CCD camera 42 on the surface of the connecting plate 41, in conjunction with the coaxial light source 43 and the backlight plate 44, performs visual positioning of the product position to facilitate the dispensing work of the right dispensing assembly 2 and the left dispensing assembly 3.

[0027] Working principle: When in use, the Z-axis linear module 12 on the surface of the support plate 11 first drives the slide 13 to move. During the movement, the displacement sensor 14 senses the displacement. When the slide 13 moves, it will drive the right dispensing assembly 2 and the left dispensing assembly 3 on the surface of the carrier 5 to move. At the same time, under the visual positioning of the vision positioning assembly 4, dual-head synchronous dispensing is performed.

[0028] Specifically, when the right dispensing assembly 2 is implemented, the X-axis lead screw module 21 drives the X-axis moving frame 22 to move along the X-axis, and the Y-axis lead screw module 23 drives the right mounting base 25 to move along the Y-axis under the action of the Y-axis moving frame 24, so that the right dispensing device 26 on the surface of the right mounting base 25 moves synchronously to complete the dispensing work.

[0029] When the left dispensing assembly 3 is implemented, the Z-axis lead screw module 32 on the surface of the fixed frame 31 drives the mounting plate 33 to move along the Z-axis. When the mounting plate 33 moves, it will drive the left dispensing device 35 on the surface of the left mounting frame 34 to complete the dispensing work.

[0030] When the visual positioning component 4 is implemented, the CCD camera 42 on the surface of the connecting plate 41 performs visual positioning of the product position in cooperation with the coaxial light source 43 and the backlight plate 44, so as to facilitate the dispensing work of the right dispensing component 2 and the left dispensing component 3.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
