Description

Technical Field

[0001] This utility model belongs to the field of dispensing machine technology, and in particular relates to a bidirectional dispensing machine with controllable dispensing. Background Technology

[0002] In the field of dispensing machine technology, traditional equipment usually adopts a single-axis or simple multi-axis structure to achieve dispensing path control. However, its motion flexibility and precision are limited, making it difficult to adapt to the needs of complex curved surfaces or high-precision micro-dispensing. Especially in high-density electronic packaging, precision semiconductor packaging or micro-mechanical assembly, traditional dispensing machines often have problems such as unstable dispensing and poor dispensing consistency.

[0003] For products requiring dispensing at two locations, existing dispensing equipment typically dispenses one location at a time, resulting in low efficiency and inconsistent dispensing. Furthermore, the frequent start-ups, shutdowns, and repositioning of the equipment increase dispensing cycle time and can lead to adhesive stringing or splattering due to inertia, affecting product appearance and performance. While some existing technologies employ dual-dispensing-head designs to improve efficiency, most solutions have inherent drawbacks. For example, using two independent motors or pneumatic components to drive each dispensing head results in high system costs, complex control, and difficulty in achieving truly synchronized dispensing. Due to differences in motor response characteristics or air pressure fluctuations, slight deviations in dispensing volume between the two heads often accumulate into significant inconsistencies over long-term operation, leading to a decrease in product yield.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0021] In one embodiment of this utility model, a controllable bidirectional dispensing machine is provided, including a base 100, and... The three-axis drive mechanism 400 includes an X-axis mechanism 500, a Y-axis mechanism 410, and a Z-axis mechanism 600. The Y-axis mechanism 410 is mounted on the base 100, the X-axis mechanism 500 is mounted on the drive end of the Y-axis mechanism 410, and the Z-axis mechanism 600 is mounted on the drive end of the X-axis mechanism 500. The dispensing mechanism 200 includes a mounting base 210, a dispensing seat 220, and a screw assembly 300. The mounting base 210 is connected to the drive end of the Z-axis mechanism 600 and is fixedly connected above the dispensing seat 220. The left and right ends of the dispensing seat 220 are respectively provided with two sets of interconnected dispensing channels 230 and dispensing channels 240. The lower ends of the two dispensing channels 230 are respectively connected to a first dispensing head 250 and a second dispensing head 260, and the two dispensing channels 240 are respectively connected to a first dispensing connector 270 and a second dispensing connector 271. The screw assembly 300 includes a rotating connector 310 and two pressure screws 320. The pressure screws 320 are respectively disposed in the corresponding glue dispensing channels 230. The rotating connector 310 is installed in the mounting base 210, and the rotating connector 310 is meshed with two auxiliary gears 340 through a main gear 330. Each auxiliary gear 340 is fixedly connected to the upper end of a pressure screw 320. The rotating connector 310 causes the two auxiliary gears 340 to rotate simultaneously, driving the two pressure screws 320 to rotate in the glue dispensing channels 230, so as to realize the simultaneous dispensing of glue from the two glue heads.

[0022] Specifically, when dispensing begins, the Y-axis mechanism 410 activates first, driving the entire X-axis and Z-axis mechanism 600 (and its dispensing mechanism 200) to move along the Y direction (back and forth) on the base 100 for coarse positioning or long-stroke movement. Next, the X-axis mechanism 500 activates, driving its Z-axis mechanism 600 and dispensing mechanism 200 to move along the X direction (left and right) for precise lateral positioning. Finally, the Z-axis mechanism 600 activates, driving its end mounting base 210 and the entire dispensing mechanism 200 to move along the Z direction (up and down), lowering the first dispensing head 250 and the second dispensing head 260 to the preset dispensing height. The rotating connector 310 includes a connecting rod 350, two bearings 360, and a support sleeve 370. The connecting rod 350 extends into the mounting base 210 from top to bottom. A rotary motor 380 is connected to the upper end of the connecting rod 350, and the lower end of the connecting rod 350 is fixedly connected to the pressure screw 320. The support sleeve 370 is installed in the mounting base 210 and sleeved on the connecting rod 350. Bearings 360 are respectively located at the upper and lower ends of the support sleeve 370, and the two bearings 360 are respectively sleeved on the upper and lower ends of the connecting rod 350. The support sleeve 370 and the bearings 360 serve to limit the connecting rod 350. The main gear 330 is fixedly connected to the lower part of the connecting rod 350. The rotary motor 380 drives the connecting rod 350 to rotate, and the main gear 330 rotates synchronously. The main gear 330 meshes with two secondary gears 340 at the same speed but in opposite directions (one clockwise and one counterclockwise). Each secondary gear 340 is directly connected to a pressure screw 320 at its lower end. The two pressure screws 320 are in opposite directions, allowing them to push downwards simultaneously when pulled. The adhesive is injected into the two inlet channels 240 through an external adhesive supply system (such as a pressure tank) from the first inlet connector 270 and the second inlet connector 271, and then pushed into the outlet channel 230. The rotating pressure screws 320 steadily deliver the adhesive downwards from the inlet channel 240 along the outlet channel 230, squeezing it out from the bottom outlet head to apply it to the pre-positioned product location. For products with dual dispensing positions, this ensures simultaneous dispensing from both outlet heads with consistent dispensing volume, improving dispensing synchronization and stability.

[0023] Furthermore, the lower end of the mounting base 210 is provided with a limiting cavity 390, which houses a main gear 330 and two auxiliary gears 340. The two auxiliary gears 340 are located at both ends of the main gear 330 and mesh with it. The main gear 330 and the auxiliary gears 340 are surrounded by the limiting cavity 390. This limiting cavity 390 is a semi-enclosed space, and its primary function is to ensure that the main gear 330 and the auxiliary gears 340 on the left and right sides always maintain precise meshing and positioning. A sealing ring 391 is provided between the limiting cavity 390 and the glue outlet channel 230 to prevent the gears from being affected by the glue.

[0024] Furthermore, the glue dispenser 220 is provided with a first glue inlet 280 and a second glue inlet 281 at its left and right ends. The first glue inlet connector 270 extends into the first glue inlet 280 to guide the glue into the corresponding glue inlet channel 240; the second glue inlet connector 271 extends into the second glue inlet 281 to guide the glue into the corresponding glue inlet channel 240. The other end of the glue inlet channel 240 is also provided with an air outlet 392 that connects to the outside, providing a balanced air pressure and preventing uneven air pressure from preventing the glue from flowing into the glue inlet channel 240.

[0025] Furthermore, the first dispensing head 250 and the second dispensing head 260 are respectively designed as inverted triangular cones. The cross-section of this type of flow channel is uniformly varied, and the colloid is guided and polymerized by the cone-shaped wall during the outflow process.

[0026] Furthermore, a mounting bracket 110 is connected to the outer wall of the mounting base 210, and an industrial camera 120 for positioning is mounted on the mounting bracket 110. The industrial camera 120 is fixed to the side wall of the mounting base 210 and moves together with the entire dispensing mechanism 200. It continuously acquires images of the working area below and transmits the data to the control system. The control system uses an image recognition algorithm to accurately calculate the coordinate deviation of the product's dispensing position, and then automatically compensates for and corrects the motion trajectory program of the three-axis drive mechanism 400.

[0027] Furthermore, the Y-axis mechanism 410 includes a Y-axis support 420, a Y-axis vertical plate 430, a Y-axis screw 440, a Y-axis motor 450, and a Y-axis guide rod 460. The Y-axis supports 420 are mounted on the base 100 in pairs, and the Y-axis vertical plate 430 is connected between the two Y-axis supports 420. The Y-axis vertical plate 430 is provided with parallel Y-axis screws 440 and Y-axis guide rods 460. The Y-axis motor 450 is mounted on one of the Y-axis supports 420, and its drive end is connected to the Y-axis screw 440 to drive it to rotate. The Y-axis screws 440 of both Y-axis vertical plates 430 are provided with X-axis moving frames 510, which move back and forth along the direction of the Y-axis guide rod 460 under the drive of the Y-axis screws 440.

[0028] Furthermore, the X-axis mechanism 500 includes two X-axis moving frames 510, an X-axis motor 520, an X-axis screw 530, and an X-axis guide rod 540. The two X-axis moving frames 510 move synchronously, and the X-axis screw 530 and the X-axis guide rod 540 are connected between the two X-axis moving frames 510. The X-axis motor 520 is mounted on one of the X-axis moving frames 510, and its drive end is connected to the X-axis screw 530 to drive it to rotate. A Z-axis moving frame 610 is mounted on the X-axis screw 530, and the Z-axis moving frame 610 moves back and forth along the direction of the X-axis guide rod 540 under the drive of the X-axis screw 530.

[0029] Furthermore, the Z-axis mechanism 600 includes a Z-axis moving frame 610, a Z-axis screw 610, a Z-axis guide rod 620, and a Z-axis motor 630. The Z-axis moving frame 610 is provided with a vertical Z-axis screw 610 and a Z-axis guide rod 620. The Z-axis motor 630 is connected to the Z-axis moving frame 610, and its driving end is connected to the Z-axis screw 610 to drive it to rotate. The Z-axis moving frame 610 traction mounting base 210 moves up and down along the direction of the Z-axis guide rod 620 under the drive of the Z-axis screw 610.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
