Description

A desktop dispensing machine Technical Field

[0001] This utility model relates to the field of spray painting machines, specifically to a desktop dispensing machine. Background Technology

[0002] A dispensing machine is a device used for spraying coatings onto the surface of parts. When spraying coatings onto parts, a dispensing machine is used to treat the surface of the parts. It is also called a glue applicator, dripping machine, glue applicator, or potting machine. It is specifically designed to control fluids and apply them to the surface or interior of products. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of dispensing machines.

[0003] Existing automatic dispensing machines mainly consist of four parts: an adhesive supply system, a motion control system, a dispensing valve, and a control system. The control system operates the dispensing machine by using air pressure or a mechanical pump to drive the adhesive from the glue tank through pipelines to the dispensing valve. Commonly used adhesive types include epoxy resin, silicone, and UV adhesive. The valve needle is pneumatically or electrically controlled to open and close, and the adhesive is extruded from the nozzle using air pressure or mechanical pressure to form a preset dispensing pattern.

[0004] However, although existing dispensing machines are mature in planar dispensing scenarios, they have significant drawbacks when dispensing on the outer surface of complex structural products. Existing dispensing guns generally approach the outer side of the product from a single direction through a vertical nozzle, causing the adhesive to flow along the direction of gravity, making it difficult to form a uniform coating layer. As a result, it is not easy to dispense adhesive evenly and stably on the side of the product. Handling outer dispensing requires repeated adjustment of the fixture angle or multiple spraying, which not only reduces production efficiency, but also introduces human error due to multiple positioning, affecting dispensing accuracy and efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned deficiencies by providing a desktop dispensing machine. This solves the technical problem in the prior art where existing dispensing guns dispense glue in a vertical, single direction, resulting in poor dispensing effect on the outer surface of the product on the corresponding fixture, thus affecting the dispensing effect and efficiency.

[0006] The objective of this utility model is achieved through the following means:

[0007] A desktop dispensing machine includes a base and a support frame mounted on the base. A movable module is connected to the support frame. A fixture is detachably connected to the base via a movable slide. A lifting module is connected to the movable module via a movable seat. A connecting device is connected to the lifting module via a lifting plate. The connecting device includes a connecting frame, a screw, an adjusting roller, and a sliding member. The connecting frame is connected to the lifting plate. The sliding member is mounted on the connecting frame. A lifting adjuster that can move along the extension direction of the sliding member is connected to the sliding member. The screw is connected to the connecting frame via a mounting block. The axial direction of the screw extends along the sliding direction of the sliding member. The adjusting roller is coaxially connected to the screw. A slot is provided on the side of the lifting adjuster to engage with the adjusting roller. The rotation of the adjusting roller along the screw can drive the lifting adjuster to move and adjust. A dispensing gun is connected to the lifting adjuster via a rotary drive component. The rotary drive component can drive the dispensing gun to tilt and adjust.

[0008] Furthermore, as described above, the lifting module is equipped with a lifting drive component, and the lifting module can drive the connecting device to move relative to the fixture via the lifting plate.

[0009] By setting up a lifting drive component, the connecting device can be precisely displaced in the vertical direction, allowing the dispensing gun to be adjusted according to the height changes of the outer surface of complex products, thereby improving coating uniformity and dispensing quality.

[0010] Furthermore, as described above, the sliding component includes a slide rail and a slider. The slide rail is mounted on a connecting frame, and the slider is paired with the slide rail. A lifting adjuster is mounted on the slider, allowing the slider to drive the lifting adjuster to move along the extension direction of the slide rail. An adjusting roller is threadedly connected to a screw, and the outer side of the adjusting roller is paired with a slot.

[0011] The cooperation between the slide rail and the slider provides a stable linear motion guide for the lifting adjuster. Combined with the threaded transmission structure of the screw and the adjusting roller, the horizontal position of the dispensing gun can be precisely adjusted, allowing multiple dispensing guns to be set and the spacing between adjacent guns to be adjusted along the sliding part. By connecting multiple dispensing guns, dispensing production efficiency can be improved.

[0012] Furthermore, as described above, the lifting adjuster consists of a connecting seat, a lifting guide block, and an adjusting rod. The lifting guide block is installed inside the connecting seat, and one end of the adjusting rod passes through the connecting seat and is connected to the lifting guide block through a guide sleeve. A slot is provided on the side of the connecting seat.

[0013] The guide sleeve structure of the lifting guide block and the adjusting rod enhances the linear motion stability of the lifting adjuster. The slot on the side of the connecting seat cooperates with the adjusting roller to further ensure accurate positioning during the adjustment process. The rotation of the adjusting roller along the screw can drive the connecting seat to move linearly.

[0014] Furthermore, as described above, the rotary drive component is composed of a rotary cylinder. The rotating end of the rotary drive component is connected to the dispensing gun via a mounting bracket, so that the rotary drive component can drive the mounting bracket to tilt and adjust the dispensing gun by rotating.

[0015] The rotary cylinder drives the dispensing gun to tilt, allowing the nozzle to approach the outer surface of the product at multiple angles. This changes the direction of adhesive flow to adapt to the side contours of complex structures, effectively reducing adhesive dripping and achieving a uniform and stable coating effect, while avoiding efficiency losses caused by multiple sprayings.

[0016] Furthermore, as described above, multiple glue guns are provided, and these multiple glue guns are connected to a sliding member via a lifting adjuster, and can move along the extension direction of the sliding member to adjust the spacing between adjacent guns.

[0017] The configuration of multiple dispensing guns, combined with the spacing adjustment function on the sliding part, allows for simultaneous dispensing operations on multiple outer areas of the product.

[0018] The beneficial effects of this utility model are as follows: By connecting the screw and adjusting roller in the connecting device and cooperating with the slot of the lifting adjuster, multiple dispensing guns can be connected. The distance between adjacent dispensing guns can be precisely adjusted by moving them along the extension direction of the sliding part. By driving the tilt adjustment of the dispensing gun through the rotary drive, the dispensing gun can approach the outer surface of the product at a non-perpendicular angle, effectively preventing the glue from flowing in a single direction along the surface or side of the product due to gravity. This ensures that the glue forms a uniform coating layer on the complex outer surface, improving the dispensing effect and production efficiency. The dispensing gun can cover dispensing areas of different heights and tilt angles on the outer side of the product through the driving of the moving module, lifting module and rotary drive, improving the applicability of the dispensing machine in the dispensing process of complex workpieces.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] This embodiment, referring to Figures 1-4, specifically implements a desktop dispensing machine, including a base 1 and a support frame 2 mounted on the base 1. A movable module 3 is connected to the support frame 2. A fixture 14 is detachably connected to the base 1 via a movable slide 4. A lifting module 5 is connected to the movable module 3 via a movable seat 13. A connecting device 7 is connected to the lifting module 5 via a lifting plate 6. The connecting device 7 includes a connecting frame 71, a screw 72, an adjusting roller 73, and a sliding member. The connecting frame 71 is connected to the lifting plate 6, and the sliding member is mounted on the connecting frame 71. A lifting adjuster 8 is provided, which can move along the extension direction of the sliding member. The screw 72 is connected to the connecting frame 71 through the mounting block 74. The axial direction of the screw 72 extends along the sliding direction of the sliding member. The adjusting roller 73 is coaxially connected to the screw 72. The side of the lifting adjuster 8 is provided with a slot 84 for engaging the adjusting roller 73. The rotation of the adjusting roller 73 along the screw 72 can drive the lifting adjuster 8 to move and adjust. A glue gun 10 is connected to the lifting adjuster 8 through a rotary drive 9. The rotary drive 9 can drive the glue gun 10 to tilt and adjust.

[0026] The lifting module 5 is equipped with a lifting drive component 11, and the lifting module 5 can drive the connecting device 7 to move relative to the fixture 14 through the lifting plate 6.

[0027] By setting up the lifting drive component 11, the connecting device 7 can be precisely displaced in the vertical direction, enabling the glue gun 10 to be adjusted according to the height changes of the outer surface of complex products, thereby improving coating uniformity and glue dispensing quality.

[0028] The sliding component includes a slide rail 75 and a slider 76. The slide rail 75 is mounted on the connecting frame 71, and the slider 76 is paired with the slide rail 75. The lifting adjuster 8 is mounted on the slider 76, so that the slider 76 can drive the lifting adjuster 8 to move along the extension direction of the slide rail 75. The adjusting roller 73 is threadedly connected to the screw 72, and the outer side of the adjusting roller 73 is paired with the slot 84.

[0029] The cooperation between the slide rail 75 and the slider 76 provides a stable linear motion guide for the lifting adjuster 8. Combined with the threaded transmission structure of the screw 72 and the adjusting roller 73, the horizontal position of the dispensing gun 10 can be precisely adjusted, allowing multiple dispensing guns 10 to be set and the spacing between adjacent guns to be adjusted along the sliding part. By connecting multiple dispensing guns 10, the dispensing production efficiency can be improved.

[0030] The lifting adjuster 8 consists of a connecting seat 81, a lifting guide block 82, and an adjusting rod 83. The lifting guide block 82 is installed inside the connecting seat 81. One end of the adjusting rod 83 passes through the connecting seat 81 and is connected to the lifting guide block 82 through a guide sleeve. A slot 84 is opened on the side of the connecting seat 81.

[0031] The guide sleeve structure of the lifting guide block 82 and the adjusting rod 83 enhances the linear motion stability of the lifting adjuster 8. The slot 84 on the side of the connecting seat 81 cooperates with the adjusting roller 73 to further ensure accurate positioning during the adjustment process. The rotational movement of the adjusting roller 73 along the screw 72 can drive the connecting seat 81 to move linearly.

[0032] The rotary drive component 9 is composed of a rotary cylinder. The rotating end of the rotary drive component 9 is connected to the dispensing gun 10 through the mounting bracket 12, so that the rotary drive component 9 can drive the mounting bracket 12 to tilt the dispensing gun 10 by rotating.

[0033] The rotary cylinder drives the dispensing gun to tilt, allowing the nozzle to approach the outer surface of the product at multiple angles. This changes the direction of adhesive flow to adapt to the side contours of complex structures, effectively reducing adhesive dripping and achieving a uniform and stable coating effect, while avoiding efficiency losses caused by multiple sprayings.

[0034] Two glue guns 10 are provided, and the two glue guns 10 are connected to the sliding member through the lifting adjuster 8, and can move along the extension direction of the sliding member to adjust the adjacent spacing.

[0035] The configuration of multiple dispensing guns 10, combined with the spacing adjustment function on the sliding part, allows for simultaneous dispensing operations on multiple outer areas of the product, adapting to the needs of products of different sizes and shapes, significantly improving dispensing efficiency, while maintaining the uniformity of coating in each area and improving overall production quality.

[0036] The movement control of the lifting adjuster 8 is achieved by using a screw 72 and an adjusting roller 73, which, together with the tilt adjustment of the rotary drive 9, improves the repeatability of the dispensing path and the coating stability. This solution, through the coordinated movement of the lifting module 5, the sliding component, and the rotary drive 9, can directly control the spatial position and tilt angle of the dispensing gun 10 without the need for angle adjustment of the fixture 14.

[0037] The specific usage process in this embodiment is as follows:

[0038] Two sets of dispensing guns 10 are connected to the sliding parts via lifting adjusters 8 and paired with adjusting rollers 73 via slots 84 of connecting seats 81. By rotating the adjusting rollers 73 along the screw 72, the lifting adjusters 8 are pushed and moved along the extension direction of the sliding parts for adjustment. Thus, the spacing between the two sets of dispensing guns 10 can be adjusted according to the needs of the product on the fixture 14 to suit the dispensing of the product. Specifically, the two sets of dispensing guns 10 are paired on opposite sides of the product, so that the two sets of dispensing guns 10 can simultaneously dispense glue to the product as the moving slide 4 moves. The glue is applied to both sides. The rotating drive component 9 drives the mounting bracket 12 to rotate and tilt the glue gun 10, allowing the glue gun 10 to approach the outer surface of the product at a non-perpendicular angle. This effectively prevents the glue from flowing along the product surface or side in a single direction due to gravity, ensuring that the glue forms a uniform coating layer on the complex outer surface, improving the glue application effect and production efficiency. At the same time, the movement module 3, the lifting module 5, and the rotating drive component 9 enable the glue gun 10 to cover glue application areas at different heights and tilt angles on the outer side of the product, improving the applicability of the glue dispensing machine in the glue application process of complex workpieces.
