Description

Technical Field

[0001] This utility model belongs to the field of dispensing machine technology, specifically a dispensing workbench and a dispensing machine. Background Technology

[0002] For example, the Chinese invention patent with authorization announcement number: CN 114377913 B, authorization announcement date: 2023.09.08, invention title: A lithium battery assembly dispensing machine describes that "the dispensing device 7 includes a horizontal moving module 70 fixed on the top of the frame 1, a flipping conveying mechanism 71 disposed on the horizontal moving module 70 and used to transfer the lithium battery 3 on the chamfering device 2 to the fixing device 5, and a dispensing conveying mechanism 72 used to dispense the lithium battery 3 on the fixing device 5 and transfer it to the stacking device 6".

[0003] The dispensing and conveying mechanism 72 includes a second bracket 721 mounted on a horizontally moving module 70 and movable under its drive, a third electric cylinder 722 vertically fixed on the second bracket 721, a third connecting plate 723 mounted on the third electric cylinder 722 and movable under its drive, a dispensing assembly 724 fixed on the third connecting plate 723, and several vacuum suction cups 725. A support plate 700 movable under its drive is mounted on the top of the horizontally moving module 70, and the bottoms of the first bracket 711 and the second bracket 721 are respectively fixed on the support plate 700. The dispensing points are applied to the large flat surface of the lithium battery 3. The amount of dispensing depends on the size of the lithium battery 3; two points can be applied to smaller batteries, and four points to larger batteries, ensuring that the two lithium batteries 3 are tightly bonded together. "Existing dispensing machines have the problem that they can only apply a small amount of dispensing to the target point and cannot apply multiple dispensings at the target location to draw the required adhesive pattern to improve the adhesive strength." Utility Model Content

[0004] Purpose of the utility model: To provide a dispensing worktable that, through the cooperation of a U-shaped photoelectric sensor, a first moving component, and a second moving component, and the fast and stable high-precision jet dispensing of a piezoelectric valve, can repeatedly dispense adhesive at the target position to draw the required adhesive pattern, thereby improving the adhesion strength.

[0005] The technical solution of this utility model is as follows: Firstly, a dispensing worktable is installed on the first moving component of a dispensing machine.

[0006] The worktable includes: a base, a second moving component, a piezoelectric valve, and a U-shaped photoelectric sensor.

[0007] The base is mounted on the first movable component.

[0008] The second moving component includes: a second Y-axis power source, a second Y-axis guide rail slider mechanism, a second Y-axis gear and rack mechanism, a second X-axis power source, a second X-axis guide rail slider mechanism, and a second X-axis gear and rack mechanism.

[0009] The second Y-axis power source and the second Y-axis guide rail slider mechanism are mounted on the base. The gear of the second Y-axis gear rack mechanism is mounted on the second Y-axis power source, and the rack of the second Y-axis gear rack mechanism is mounted on the second Y-axis guide rail slider mechanism.

[0010] The second X-axis power source and the second X-axis guide rail slider mechanism are mounted on the second Y-axis guide rail slider mechanism. The gear of the second X-axis gear rack mechanism is mounted on the second X-axis power source, and the rack of the second X-axis gear rack mechanism is mounted on the second X-axis guide rail slider mechanism.

[0011] The piezoelectric valve and the U-shaped photoelectric sensor are mounted on the second X-axis guide rail slider mechanism of the second moving component, which is used to drive the piezoelectric valve and the U-shaped photoelectric sensor to move horizontally.

[0012] In a further embodiment of the first aspect, the second Y-axis gear and rack mechanism includes: a second Y-axis gear and a second Y-axis rack.

[0013] The rotation axis of the second Y-axis gear is vertically oriented.

[0014] The tooth surface of the second Y-axis rack is disposed on the vertical surface of the rack, so that the second Y-axis gear meshes with the vertical surface of the second Y-axis rack.

[0015] In a further embodiment of the first aspect, the second X-axis gear rack mechanism includes: a second X-axis gear and a second X-axis rack.

[0016] The rotation axis of the second X-axis gear is vertically oriented.

[0017] The tooth surface of the second X-axis rack is set on the vertical surface of the rack, so that the second X-axis gear meshes with the vertical surface of the second X-axis rack. This allows the second Y-axis power source and the second X-axis power source to be set vertically along the central axis of the gear, so that their length and width dimensions are smaller than their height dimensions, further reducing the length and width of the worktable.

[0018] In a further embodiment of the first aspect, the second Y-axis power source includes: a second Y-axis reducer and a second Y-axis servo motor.

[0019] The second Y-axis reducer is mounted on the base, and the second Y-axis servo motor is mounted on the second Y-axis reducer.

[0020] The gears of the second Y-axis gear rack mechanism are mounted on the second Y-axis reducer.

[0021] In a further embodiment of the first aspect, the second X-axis power source includes: a second X-axis reducer and a second X-axis servo motor.

[0022] The second X-axis reducer is mounted on the second Y-axis guide rail slider mechanism, and the second X-axis servo motor is mounted on the second X-axis reducer.

[0023] The gear of the second X-axis gear rack mechanism is mounted on the second X-axis reducer. Based on the high-precision servo motor, the reducer is used as a power source, which can improve the working accuracy of the second Y-axis and the second X-axis movement from the power source level.

[0024] In a further embodiment of the first aspect, the base is provided with reinforcing ribs to enhance its resistance to deformation.

[0025] In a second aspect, a dispensing machine includes: a first moving component, and the dispensing worktable described in the first aspect.

[0026] The first moving component includes a first Y-axis motion mechanism, a first X-axis motion mechanism, and a first Z-axis motion mechanism connected in sequence.

[0027] The three dispensing worktables are mounted on the first Z-axis motion mechanism.

[0028] The beneficial effects of this utility model are as follows: By combining a U-shaped photoelectric sensor, a first moving component, and a second moving component, this application, compared with the prior art which only uses one set of moving components, can not only use a large-span first moving component to increase the moving speed and meet the need for large-span movement of dispensing to improve dispensing efficiency, but also use the U-shaped photoelectric sensor to detect the position, then use the second moving component to adjust the position of the piezoelectric valve, and then use the second moving component to drive the piezoelectric valve to move to ensure the moving accuracy of the piezoelectric valve. In addition, combined with the fast and stable high-precision jet dispensing of the piezoelectric valve, it can apply dispensing multiple times at the target position to draw the required adhesive pattern to improve the adhesive strength. This solves the problem that the existing dispensing machine can only apply a small amount of dispensing to the target point and cannot apply dispensing multiple times at the target position to draw the required adhesive pattern to improve the adhesive strength.

[0029] Moreover, the X and Y axes are moved through a power source and a gear and rack mechanism. The power source can be vertically set on one side of the rack, which greatly reduces the size of the worktable in the X and Y axis directions, allowing multiple worktables to be set on the first moving component for coordinated operation.

[0057] Three dispensing worktables 1 are mounted on the first Z-axis motion mechanism 23.

[0059] Working method: First, the product to be glued is fixedly installed on the dispensing machine using tooling. According to the process requirements, the motion trajectory and positioning coordinates of the worktable in the XY plane are set in the control system. After the equipment is started, the control system sends motion commands to the first moving component and the second moving component. After the first moving component moves the second moving component to the predetermined position, the three second moving components drive multiple piezoelectric valves 17 to move. At the same time, the multiple piezoelectric valves 17 spray a large amount of glue onto the product with fast, stable and high precision. Multiple glue dispensings at the target position draw the required adhesive pattern to improve the adhesion strength.
