Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to a dual-workstation dispensing mechanism. Background Technology

[0002] Traditional dispensing equipment requires flipping a workpiece when dispensing glue to both the top and sides. This allows the equipment to dispense glue to different locations. However, this method can affect dispensing accuracy due to the flipping, and the dispensing time for a single workpiece is long due to the large number of dispensing locations, resulting in low dispensing efficiency.

[0003] Furthermore, if it is necessary to apply glue to two types of workpieces on the same fixture, one workpiece requires glue to be applied to its top surface and the other workpiece requires glue to be applied to its side surface, a five-axis machine can meet this requirement. However, the five-axis machine has a higher equipment cost and can only apply glue to one workpiece at a time, resulting in lower efficiency. Utility Model Content

[0028] This utility model discloses a dual-point adhesive mechanism.

[0029] Reference Figures 1 to 7 A dual-workstation dispensing mechanism includes a frame 1 and a three-axis motion mechanism mounted on the frame 1. The three-axis motion mechanism includes an X-axis moving component 21, a first Y-axis moving component 22, a first Z-axis moving component 23, and a second Z-axis moving component 24. The first Y-axis moving component 22 is connected to the frame 1, the X-axis moving component 21 is connected to the first Y-axis moving component 22, and the first Z-axis moving component 23 and the second Z-axis moving component 24 are connected to the X-axis moving component 21. The frame 1 is also equipped with a first dispensing device 3 and a second dispensing device 4. The first dispensing device 3 is connected to the first Z-axis moving component 23 and can move along the X, Y, and Z directions. The first dispensing device 3 includes a rotary mechanism 31 that rotates around the B-axis, an angular swing mechanism 32 that swings around the A-axis, and a first dispensing valve 34 connected to the angular swing mechanism 32. The angular swing mechanism 32 is connected to the rotary mechanism 31, and the first dispensing valve 34 can perform dispensing operations on the side of the workpiece. The second dispensing device 4 is connected to the second Z-axis moving assembly 24. The second dispensing device 4 can move along the X, Y and Z directions and can perform dispensing operations on the top surface of the workpiece.

[0030] The first Z-axis moving assembly 23 is also connected to a vision recognition mechanism 35. The vision recognition mechanism 35 and the first dispensing device 3 are arranged opposite each other on both sides of the first Z-axis moving assembly 23 along the X direction, so that the weight on both sides of the first Z-axis moving assembly 23 tends to be balanced, improving the stability of the first dispensing device 3 when moving. The vision recognition mechanism 35 is used to photograph the workpiece, which facilitates the dispensing device to perform precise dispensing.

[0031] The visual recognition mechanism 35 includes a lens barrel 351, a camera 352, and a light deflector 353. A mounting plate is connected to the movable end of a first Z-axis moving member. The lens barrel is positioned along the Z-axis and mounted on the mounting plate. The camera 352 is horizontally positioned; in this embodiment, the camera 352 is positioned along the X-axis and mounted on the mounting plate. The light deflector 353 is mounted on the lens barrel 351 and located between the lens barrel 351 and the camera 352. The light deflector 353 can reflect the pattern acquired by the lens barrel 351 to the camera 352.

[0032] Specifically, the light deflector 353 includes a mounting housing 3531 and a reflector 3532. The reflector 3532 is obliquely mounted inside the mounting housing 3531, and is positioned facing both the lens barrel 351 and the camera 352. The mounting housing 3531 is open on both sides facing the camera 352 and the lens barrel 351 to allow light to pass through. Preferably, the angle between the reflector 3532 and the axis of the camera 352 is 45 degrees, and the angle between the reflector 3532 and the axis of the lens barrel 351 is 45 degrees, so that the image reflected to the camera 352 has the same size and aspect ratio as the image acquired by the lens barrel 351.

[0033] It should be noted that the second Z-axis moving component 24 is also connected to the aforementioned visual recognition mechanism 35, and the installation position is the same, so it will not be described in detail.

[0034] Specifically, the angle adjustment component 23 includes a mounting base 231, a linear drive component 232, and a rotating base 233. The mounting base 231 is fixedly connected to the movable end of the rotating component 22. The linear drive component 232 includes a drive motor 2321, a lead screw 2322, and a lead screw seat 2323. The drive motor 2321 is fixedly mounted on the mounting base 231. The lead screw 2322 is arranged along the Z-axis direction and is coaxially fixedly connected to the output end of the drive motor 2321. The lead screw seat 2323 is slidably connected to the mounting base 231 along the Z-axis direction and is threadedly connected to the lead screw 2322.

[0035] The rotating seat 233 is arranged along the Y-axis and is rotatably connected to the mounting seat 231. One end of the rotating seat 233 is fixedly connected to the first dispensing valve 24, and the other end passes through the mounting seat 231 and is fixedly connected to a swing plate 236. Two slide rails 235 are fixedly connected to the swing plate 236. A mating plate 237 is fixedly connected to the thread holder 2323, and two slide blocks 234 are fixedly connected to the mating plate 237. The two slide rails 235 are slidably connected to the two slide blocks 234 respectively.

[0036] The swing plate 236 has a mating groove 2361 for the mating plate 237 to pass through. The mating plate 237 and the mating groove 2361 are mated together, which can further improve the stability of the movement between the slide rail 235 and the slide block 234. At the same time, this setting can make the fit between the slide block 234 and the slide rail 235 tighter, thereby improving the rotation accuracy of the rotating seat 233.

[0037] The swing plate 236 and the first dispensing valve 24 are arranged on both sides of the mounting base 231 along the Y-axis direction, which can reduce the possibility of interference between the swing plate 236, the slide 234 and other structures and the first dispensing valve, provide sufficient space for the dispensing assembly, and at the same time, make the weight on both sides of the mounting base 231 balanced, thus improving the stability of the dispensing operation.

[0038] It should be noted that in this embodiment, the first dispensing valve 24 swings at an angle of ±45 degrees along the Z-axis.

[0039] In addition, the second dispensing device includes a second Y-axis moving assembly and a second dispensing valve. The second Y-axis moving assembly is connected to the second Z-axis moving assembly, and the second dispensing valve is connected to the second Y-axis moving assembly. The second Y-axis moving assembly facilitates fine adjustment of the second dispensing valve along the Y direction, improving the flexibility of dispensing.

[0040] It should be noted that the first dispensing valve and the second dispensing valve include a dispensing frame and a dispensing head mounted on the dispensing frame, and dispensing is achieved through the dispensing head.

[0041] In addition, the rotating mechanism 31 can be a stepper motor, while the X-axis moving component 21, the first Y-axis moving component 22, the first Z-axis moving component 23, the second Z-axis moving component 24 and the second Y-axis moving component 41 can be linear modules or lead screw 3222 mechanisms, as long as they can realize the reciprocating movement of the dispensing device.

[0042] Working principle: The first dispensing device 3 and the second dispensing device 4 can dispense glue to the side and top surfaces of the workpiece respectively, which can meet the needs of dispensing glue to multiple positions of the workpiece or dispensing glue to different workpieces on the same fixture. The workpiece does not need to be flipped, and the dispensing accuracy is high. At the same time, the first dispensing device 3 and the second dispensing device 4 can work independently, which can improve dispensing efficiency. In addition, the assembly and debugging requirements of the first dispensing device 3 and the second dispensing device 4 are low, so the cost is low.

[0043] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
