Description

Technical Field

[0001] The utility model relates to the technical field of dispensing, and particularly refers to an online dispensing machine with UV curing. Background Art

[0002] In various fields of modern industrial production, dispensing technology has become an indispensable part. As the core equipment for realizing dispensing technology, the dispensing machine is widely used in many industries such as electronics, automotive, medical, LED lighting, and solar energy because it can achieve high-precision and high-efficiency fluid control. With the continuous progress of technology, the dispensing machine is also constantly developing and innovating to meet the increasing industrial production requirements.

[0003] After the existing dispensing machines complete dispensing, they will all be cured by UV. For example, a UV glue dispensing and curing integrated device disclosed in the prior art CN218590978U is provided with a UV dispensing head and a light source curing head, which are integrated on the same frame. Through the mutual cooperation of the first and second X-axis moving mechanisms, the first and second Y-axis moving mechanisms, and the first and second Z-axis moving mechanisms, the UV dispensing head can be quickly and accurately moved to the position where dispensing is required, and then the product after dispensing is quickly and stably moved to the position below the light source curing head for ultraviolet light irradiation curing; however, there are the following problems:

[0004] 1. Manual loading and unloading are required, with high labor intensity and time-consuming and laborious.

[0005] 2. The UV dispensing head and the light source curing head are integrated on the same frame. Although this makes the overall structure compact, small in volume, and occupies less space, after each dispensing is completed, it is still necessary to wait for curing, resulting in low work efficiency.

[0006] Another example is a UV dispensing and curing device disclosed in CN213558053U. By setting a dispensing mechanism and a UV curing mechanism on the workbench, and through a conveying mechanism, a lifting assembly, a first blocking assembly, and a second blocking assembly to convey and position the carrier, and also through a displacement mechanism to move the dispensing head, automatic dispensing and curing are achieved; however, there are the following problems:

[0007] 1. The conveying mechanism uses a single conveyor belt to convey multiple jigs throughout the process. When dispensing and curing, blocking components need to be set respectively, and a lifting assembly also needs to be set separately for dispensing. Not only is the structure complex, but also the flexibility is low.

[0008] 2. The width of the conveying mechanism cannot be adjusted, and only carriers or PCB boards with a fixed width can be conveyed, resulting in poor compatibility. Content of the Utility Model

[0036] Appendix Figure 1-2 The on-line glue dispensing machine with UV curing according to the present utility model includes a machine platform 1, a conveyor line 2 provided on the machine platform 1, a glue dispensing mechanism 3 provided on the machine platform 1 and placed along the conveying direction of the conveyor line 2, and a curing mechanism 4.

[0037] The conveyor line 2 adopts a double-row belt conveyor line, wherein the width of the double-row belt conveyor line is adjustable and is divided into two sections for conveying, corresponding to the glue dispensing mechanism 3 and the curing mechanism 4 respectively.

[0038] The glue dispensing mechanism 3 includes an XYZ-axis linear module 31 located above the conveyor line 2, a glue dispensing assembly 32 and a vision assembly 33 respectively provided at the driving end of the XYZ-axis linear module 31.

[0039] The curing mechanism 4 includes a curing bracket 41 located above the conveyor line 2 and a UV curing lamp 32 provided on the curing bracket 41.

[0040] During operation: The two ends of the conveyor line 2 are respectively connected to the upstream and downstream conveyor lines. After the equipment in the previous process completes processing, it will automatically convey the product to the conveyor line 2 of this equipment; the conveyor line 2 conveys the product to be glue-dispensed to the glue dispensing mechanism 3. First, the vision assembly 33 takes a photo to identify and position the product to be glue-dispensed, and then the glue dispensing assembly 32 performs glue dispensing; after the glue dispensing is completed, the vision assembly 33 takes a photo to identify whether there is any missed glue dispensing; if there is no missed glue dispensing, the conveyor line 2 conveys the glue-dispensed product to the curing mechanism 4, and cures it through the UV curing lamp 32, and finally sends it to the equipment in the next process for processing; if there is missed glue dispensing, the glue dispensing assembly 32 continues to perform glue dispensing until the vision assembly 33 detects that it is qualified and there is no missed glue dispensing, and then sends it to the curing mechanism 4 through the conveyor line 2 for curing, and finally sends it to the equipment in the next process for processing.

[0041] Among them, the double-column belt conveyor line is a prior art, and reference can be made to the small double-column width-adjustable flat belt conveyor line disclosed in CN212049084U. Therefore, its structure will not be described in detail, but its width can be adjusted electrically or manually.

[0042] Furthermore, as Figure 1-2 shown, the dispensing mechanism 3 further includes a waste glue discharging assembly 34 disposed on the machine table 1 for storing waste glue; the waste glue discharging assembly 34 includes a discharging rack 341 and a discharging box 342 detachably disposed on the discharging rack 341; when the equipment stops for a long time, to prevent the glue at the glue outlet of the dispensing assembly 32 from contacting the air and deteriorating, during the initial gluing, the glue at the glue outlet of the dispensing assembly 32 can be discharged into the discharging box 342; the discharging box 342 is detachably disposed on the discharging rack 341, which is convenient for removal, cleaning or replacement.

[0043] Furthermore, as Figure 1 shown, the dispensing mechanism 3 further includes a cleaning assembly 35 for cleaning the glue outlet of the dispensing assembly 32; in an abnormal state, the XYZ-axis linear module 31 drives the glue outlet of the dispensing assembly 32 to insert into the cleaning assembly 35, and the cleaning assembly 35 cleans the glue outlet of the dispensing assembly 32 to prevent some glue from solidifying at the glue outlet of the dispensing assembly 32 and affecting the dispensing effect; the cleaning assembly 35 is a prior art, and reference can be made to a glue dispensing needle cleaning device and a coating machine disclosed in CN220048691U, so its structure will not be described in detail.

[0045] Furthermore, as Figure 3-4As shown in the figure, a clamping assembly 22 for fixing the product to be dispensed is further provided at the dispensing station on the conveyor line 2; the clamping assembly 22 includes a clamping seat 221 provided on the bracket of the conveyor line 2, a clamping cylinder 222 horizontally arranged on the clamping seat 221, and a clamping plate 223 horizontally arranged at the driving end of the clamping cylinder 222 for abutting against the product to be dispensed for fixing; when the product to be dispensed is transported to the dispensing station and stopped by the material blocking assembly 21, the clamping plate 223 is driven by the clamping cylinder 222 to abut against the product to be dispensed for fixing, realizing mechanical positioning + visual positioning, and further improving the dispensing accuracy.

[0046] Furthermore, as Figure 5 shown, a protective cover 12 with openings 11 at both ends is provided on the machine table 1, which plays a role of safety protection;

[0047] The conveyor line 2, the dispensing mechanism 3 and the curing mechanism 4 are all located inside the protective cover 12, and both ends of the conveyor line 2 extend out of the openings 11 at both ends of the protective cover 12 respectively, facilitating online operation.

[0048] Furthermore, as Figure 5 shown, a button panel 13 is provided on the front of the protective cover 12, an adjustable support frame 14 is provided on one side, and an alarm lamp 16 for displaying the working state is provided on the top; the support frame 14 is used to place the display 15, as well as the mouse and keyboard, facilitating the daily operation of the equipment by the staff.
