Description

Technical Field

[0001] The present invention is applied to the technical field of glue dispensing mechanisms, and particularly relates to a double-valve glue dispensing module. Background Art

[0002] In the current dispensing industry, single-valve dispensing equipment is generally used. The design of the double-valve dispensing module can improve the production dispensing efficiency of the equipment. Depending on the software algorithm, the double valve can dispense the same product at the same time, or different products. In the market, double-valve dispensing equipment is relatively rarely used, and many are semi-automatic or manually controlled, with low efficiency and unstable dispensing effect. Therefore, the design of fully automatic double-valve dispensing has a broad market space. In terms of hardware, it is necessary to be able to realize the three-axis adjustment function of the position of the second set of dispensing valves relative to the first set of dispensing valves while meeting the size of most products in the industry. It is also necessary to consider the exchange of the position of the camera used to obtain the image with the first set of dispensing valves, and the structure of the entire module cannot be too heavy to affect the operation, or too large to occupy the equipment dispensing area. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a double-valve dispensing module which is small in size, flexible in control and precise in movement.

[0004] The technical solution adopted by the present invention is: the present invention includes a mounting plate, a first dispensing valve, a second dispensing valve and a visual module, the first dispensing valve and the visual module are both fixed on the mounting plate, the second dispensing valve is connected to the mounting plate through a three-axis fine-tuning mechanism, the three-axis fine-tuning mechanism includes an X-axis assembly, a Y-axis assembly and a Z-axis assembly connected in sequence, the Y-axis assembly includes an L-shaped movable frame, a Y-axis motor, a first triangular slide and a second triangular slide, the X-axis assembly drives the L-shaped movable frame to move horizontally, the Y-axis motor is fixed to the L-shaped movable frame in a vertical direction, the first triangular slide is slidably matched with the L-shaped movable frame in a vertical direction and is connected to the output shaft of the Y-axis motor, the second triangular slide is slidably matched with the L-shaped movable frame in a horizontal direction, the first triangular slide is provided with a first slide rail, the second triangular slide is provided with a second slide rail slidably matched with the first slide rail, the first slide rail is inclined to the axial setting of the Y-axis motor, and the Z-axis assembly is fixed to the second triangular slide.

[0005] As can be seen from the above scheme, the positions of the first dispensing valve and the second dispensing valve can be interchanged. By setting the three-axis fine-tuning mechanism, the position of the second dispensing valve relative to the first dispensing valve can be adjusted, so that the first dispensing valve and the second dispensing valve can be coordinated to perform dispensing of the same product, or two products can be synchronously dispensed separately, thereby improving the efficiency and accuracy of the dispensing process. The interpolation method is realized by combining the first triangular slide and the second triangular slide to realize the adjustment of the Y axis, so that the three-axis fine-tuning mechanism is more compact as a whole, which can save a lot of space and provide sufficient space for the installation of other components. At the same time, the weight of the overall mechanism is reduced to prevent the operation of the driving device from being affected. The first triangular slide and the second triangular slide are designed to be inclined to the axial setting of the Y-axis motor, so that when the Y-axis motor drives the first triangular slide forward, the first slide rail and the second slide rail are cooperated to drive the second triangular slide to drive the Z-axis assembly to move along the Y-axis direction, and there is no need to set the motor along the Y-axis direction. The first triangular slide and the second triangular slide slide slide on the two mutually perpendicular end faces of the L-shaped movable frame respectively. The Y-axis motor is a stepper motor.

[0006] A preferred solution is that the X-axis assembly includes an X-axis motor, a first screw and a first nut, the X-axis motor is fixed on the mounting plate, the first screw is rotatably engaged on the mounting plate, one end of the first screw is drivingly connected to the output shaft of the X-axis motor, the first nut is fixed on the L-shaped movable frame, the first nut is sleeved on the first screw, and when the X-axis motor drives the first screw to rotate, it drives the L-shaped movable frame to move horizontally in the horizontal direction.

[0007] It can be seen from the above scheme that the X-axis motor drives the first screw to rotate, thereby driving the first nut to move along the axial direction of the first screw. The first screw is a tightly ground screw to provide a higher displacement precision. The X-axis motor is a stepping motor.

[0008] A preferred solution is that the L-shaped movable frame is slidably engaged on the mounting plate via a guide rail.

[0009] It can be seen from the above solution that the guide rail is provided to guide the L-shaped movable frame, thereby improving the movement accuracy of the second dispensing valve in the Y-axis direction.

[0010] A preferred solution is that the Z-axis assembly includes a Z-axis motor and a mounting block arranged parallel to the Y-axis motor, the Z-axis motor is fixed on the second triangular slide, the mounting block is slidably fitted on the second triangular slide, the second dispensing valve is fixed on the mounting block, and the Z-axis motor drives the mounting block to move up and down in the vertical direction through the cooperation of the second screw and the second nut.

[0011] It can be seen from the above solution that by adopting the Z-axis motor arranged in parallel with the Y-axis motor, each component can be made more compact.

[0012] A preferred solution is that the vision module includes an industrial camera and a laser sensor fixed on the mounting plate.

[0013] It can be seen from the above scheme that the industrial camera is used to obtain the image data required for the operation of the double-valve dispensing module, and then realize movement according to the image data, and the laser sensor is used to detect the distance between the double-valve dispensing module and the product to be dispensed.

[0014] A preferred solution is that the first dispensing valve and the second dispensing valve both include a glue cartridge, a heated glue injection head and an adjustment seat, the heated glue injection head is fixed to the movable end of the adjustment seat, and the glue cartridge is connected to the heated glue injection head via a pipeline.

[0015] As can be seen from the above scheme, the glue cylinder is used to carry glue liquid, the heated glue injection head is used to heat the glue liquid and perform glue dispensing operations, and the adjustment seat is used to adjust the height position of the heated glue injection head.

[0016] A preferred solution is that two groups of in-place sensors are arranged on the mounting plate, and the two groups of in-place sensors are respectively arranged at the end points of the movable travel of the L-shaped movable frame, and the L-shaped movable frame is provided with a sensing sheet that cooperates with the in-place sensors.

[0017] It can be seen from the above solution that by setting the in-position sensor to detect the position of the L-shaped movable frame, the L-shaped movable frame is prevented from moving beyond the limit and causing the components to collide with each other. BRIEF DESCRIPTION OF THE DRAWINGS
