Description

Technical Field

[0001] The utility model relates to the field of glue dispensing equipment, in particular to a rotary glue dispensing device capable of automatically aligning needles. Background Art

[0002] A dispensing device is a device that uses a glue needle to dispense glue on products. Existing dispensing devices can only dispense glue on holes of specific sizes and are not compatible with dispensing glue on inner holes and outer circles of products of various sizes. In addition, its mechanism is difficult to debug and has no automatic needle alignment function, requiring manual debugging. This limits the application scenarios and reduces dispensing efficiency.

[0003] For example, Chinese patent publication number CN 212189829 U discloses a rotary glue dispensing machine with an automatic needle alignment mechanism. The machine includes a controller, a three-dimensional worktable consisting of X, Y, and Z axes, a rotating mechanism fixed to the Z axis, a glue dispensing controller, a glue cartridge and a needle, a movable carrier, and a needle alignment mechanism fixed to the movable carrier. The needle alignment mechanism includes an X-direction sensor, a Y-direction sensor, and a cross-shaped groove. Because the needle of this rotary glue dispensing machine is always in a vertical position, it is not convenient for dispensing glue to outer circles or inner holes, limiting its use.

[0004] In view of this, it is necessary to provide a rotary dispensing device with automatic needle alignment. Summary of the Invention

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, an embodiment of the present application provides a rotary dispensing device that can automatically align needles, and its structure includes a base 1, a dispensing mechanism 2 arranged on the base 1, and a fixture platform 3, the dispensing mechanism 2 includes a support 21 arranged on the base 1, a moving component 22 arranged on the support 21, a rotating shaft 23 arranged vertically on the moving component 22, a motor 24 arranged on the moving component 22 for driving the rotating shaft 23 to rotate, a connecting frame 25 arranged at the lower end of the rotating shaft 23, a rotating cylinder 26 arranged on the connecting frame 25, and a glue needle 27 arranged at the output end of the rotating cylinder 26, an angle is formed between the glue needle 27 and the rotating shaft 23, and the glue outlet of the glue needle 27 is located below the rotating shaft 23, the fixture platform 3 includes a mounting platform 31, a moving platform 32 arranged on the base 1 for driving the mounting platform 31 to move, and a cross-needle optical fiber 33 arranged on the mounting platform 31.

[0019] During actual use, the product to be glued is placed on the mounting platform 31, and then the mobile platform 32 drives the mounting platform 31 to move. The mobile component 22 drives the rotating shaft 23 to move, and the motor 24 drives the rotating shaft 23 to rotate, driving the rotating cylinder 26 and the glue needle 27 to rotate synchronously to achieve glue dispensing of the product. When the needle or glue barrel of the glue needle 27 is replaced, the needle tip coordinates of the glue needle 27 will change, that is, the glue outlet coordinates of the glue needle 27 will change. At this time, the rotating cylinder 26 is required to drive the glue needle 27 to a vertical state, and then the mobile component 22 drives the rotating shaft 23 to move, so that the needle tip of the glue needle 27 is placed in the cross-needle optical fiber 33. The coordinated movement of the mobile component 22 and the mobile platform 32 corrects the needle tip coordinates of the glue needle 27 to achieve automatic needle alignment.

[0020] In the above design, the rotating cylinder 26 drives the glue needle 27 to rotate to an inclined position, and the rotation of the rotating shaft 23 can achieve glue dispensing on the inner wall of the hole or the outer wall of the cylinder. The glue needle 27 can also be moved horizontally in a vertical position to dispense glue or dispense glue along with the movement of the rotating shaft 23, realizing diversified glue dispensing application scenarios. The cross-needle alignment optical fiber 33 can automatically achieve automatic needle alignment, improving the accuracy and efficiency of the needle calibration of the glue needle 27.

[0021] Specifically: Figure 2 As shown, the mounting platform 31 includes a discharge plate 311 arranged on the movable platform 32, a No. 1 limit bar 312 arranged on the front side of the discharge plate 311, a No. 2 limit bar 313 arranged on the left side of the discharge plate 311, a No. 1 cylinder 314 arranged on the right side of the discharge plate 311 along the left-right direction, a No. 1 push plate 316 fixedly arranged at the output end of the No. 1 cylinder 314, a No. 2 cylinder 315 arranged on the rear side of the discharge plate 311 along the front-back direction, and a No. 2 push plate 317 fixedly arranged at the output end of the No. 2 cylinder 315.

[0022] In actual use, the product is placed on the discharge plate 311, and then the No. 1 cylinder 314 drives the No. 1 push plate 316 to push the product against the No. 2 limit bar 313, and the No. 2 cylinder 315 drives the No. 2 push plate 317 to push the product against the No. 1 limit bar 312, so that the four sides of the product are positioned.

[0023] In the above design, the product can be effectively positioned to ensure that the product dispensing process is always in a stable state and the accuracy of dispensing is ensured.

[0024] Specifically: Figure 2 As shown, a notch 301 is provided on the left side of the discharge plate 311, which passes through the upper and lower end surfaces of the discharge plate 311. The notch 301 extends in the left-right direction and protrudes to the right side of the second limiting strip 313.

[0025] In actual use, after the product is dispensed, the first cylinder 314 drives the first push plate 316 to separate from the product, and the second cylinder 315 drives the second push plate 317 to separate from the product. The product is grabbed from the notch 301 and transferred.

[0026] In the above design, by providing the notch 301 , the product can be quickly clamped and transferred from the notch 301 after the product dispensing is completed without affecting the positioning of the product.

[0027] Specifically: Figure 1 and Figure 3As shown, the movable platform 32 is a No. 1 linear module, which is arranged on the base 1 along the Y direction. The movable assembly 22 includes a No. 2 linear module 222221 arranged on the support 21 along the X direction, a No. 3 linear module arranged at the output end of the No. 2 linear module 222221 along the Z direction, and a mounting bracket fixedly arranged at the output end of the No. 3 linear module. The rotating shaft 23 is rotatably arranged on the mounting bracket.

[0028] During actual use, the mounting platform 31 is driven to move in the Y direction by the No. 1 linear module, and the No. 2 linear module 222221 is used to drive the No. 3 linear module to move in the X direction, thereby realizing the movement of the glue needle 27 in the X direction, and the No. 3 linear module is used to drive the glue needle 27 to rise and fall in the Z direction, thereby realizing the movement of the XYZ axis of the glue dispensing track.

[0029] The above design can realize three-axis drive of the dispensing track.

[0030] Specifically: Figure 2 As shown, a plurality of supporting legs 4 are provided on the lower end surface of the base 1 .

[0031] During actual use, the base 1 is supported by the supporting glue.

[0032] In the above design, the support legs 4 are provided to effectively support the base 1 and ensure the stability of the base 1 .

[0033] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
