Description

Technical Field

[0001] The utility model relates to the technical field of glue coating equipment, in particular to a backboard primer coating equipment. Background Art

[0002] With the development of electronic products, various smart devices have entered the lives of ordinary consumer families. Due to the fierce competition in electronic products, the technical process, output and performance requirements of electronic components are gradually increasing. For example, the primer process of the back panel of electrical equipment requires a higher level of automation, higher coating efficiency and precision.

[0003] There are some shortcomings in today's automated operation processes. For example, commonly used fixture flow channel types include synchronous belt flow channels, fork flow channels, and belt flow channels with accessories, etc. However, the operating fixtures that cooperate with existing conveyor lines often cannot guarantee fast, vibration-free, and friction-free movement positioning and reflux, and the conveyor line cannot protect the fixtures and processed products well during operation. Specifically, the patent document with application number 202020226009.5 discloses a "multi-axis robot arm spraying equipment", which uses a conveyor belt to transport products and identify and determine the spraying path. Since the product is deformed by the pressure of the conveyor belt, the position and posture change during the conveying process, resulting in a decrease in the accuracy of the spraying path, affecting the final spraying effect.

[0004] It can be seen that the current backplane primer solution still has room for improvement and should be optimized to improve the efficiency and stability of the fixture movement positioning and improve the protection of the fixture and products. Therefore, a more reasonable technical solution should be proposed to solve the technical problems existing in the existing technology. Utility Model Content

[0005] In order to overcome at least one of the above-mentioned defects, the utility model provides a backplane primer coating device.

[0006] In order to achieve the above purpose, the primer equipment disclosed in the utility model can adopt the following technical solutions:

[0007] A backplane primer coating device, comprising:

[0008] A conveyor line assembly, comprising a plurality of rigid conveying members arranged continuously along a conveying path to convey the product to be coated with glue, and a blocker is arranged on the conveyor line to assist in positioning the product to be coated with glue;

[0009] A manipulator assembly is used to connect the detachable spray assembly and drive the spray assembly to move, so as to align the spray assembly with the spray point;

[0010] A spraying component is connected to the manipulator component through a joint, and the spraying component includes a spraying part for spraying glue, a height detection part for detecting the current spraying height, and an array camera component for obtaining the spraying effect in real time;

[0011] The guiding assembly includes several guiding cameras facing the conveyor line assembly, which are used to obtain the position of the product to be coated with glue and determine the spraying point.

[0012] The primer coating equipment disclosed above transports the product to be coated with glue through a conveyor line component, moves the spray component to a correct position through a robot component, and then sprays after being guided to the correct position by a guide component, thereby achieving the effect of precise spraying of the product.

[0013] Furthermore, the rigid conveyor can ensure the stability of the product conveying and gluing process, and its structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the rigid conveyor includes a roller. When such a solution is adopted, the rollers are several in number and are arranged continuously along the conveying direction.

[0014] Furthermore, the blocker is located on the conveyor assembly and is used to limit the progress of the product to be glued. The specific structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the blocker includes a block that moves relative to the conveyor, but when the block is in the interference position, it abuts against the product to be glued and prevents it from moving. When the block is in the release position, it is away from the product to be glued and allows the product to be glued to move along with the conveyor assembly. When such a solution is adopted, the block can be driven to move up and down by setting a lifting mechanism, and the block is located between two adjacent rollers and rises or falls from the gap.

[0015] Furthermore, the spray assembly can be constructed into a variety of structures and is not limited to a single one. Here, an optimization is performed and one feasible option is proposed: the spray assembly includes a spray rack that cooperates with the joint, and a lateral adjustment structure is provided on the spray rack to adjust the position of the spray part.

[0016] Furthermore, in this embodiment, the height of the spray assembly can be detected by a variety of schemes, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the height detection member includes a laser sensor. When such a scheme is adopted, the laser sensor is vertically downward to detect the current height of the spray assembly, which is convenient for subsequent adjustment and spraying operation.

[0017] Furthermore, in order to better detect the spraying position and improve the accuracy of spraying, optimization is performed here and one of the feasible options is proposed: the area array camera assembly includes a plurality of area array detection cameras, and the area array detection cameras are illuminated by corresponding detection light sources.

[0018] Furthermore, the glue spraying part can be constructed in various forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the glue spraying part includes a glue spraying valve, and the glue spraying valve is connected to a calibration plate for calibrating the glue spraying position. When such a solution is adopted, the calibration plate is fixedly connected to the glue spraying valve and moves synchronously.

[0019] Furthermore, the guide assembly can adopt a variety of structures, which are not limited to the only one. Here, we optimize and propose one feasible option: the guide assembly includes a guide frame, and the guide camera is connected and arranged on the guide frame. When such a solution is adopted, the guide frame is used for connection and fixing, providing a force point to connect the guide camera and drive the guide camera to move.

[0020] The structure of the guide frame is not limited by displacement, and can be constructed in various forms, and is not limited to a single form. Here, an optimization is made and one of the feasible options is proposed: the guide frame is set on the device body, and an adjustment block is set on the device body and the guide frame is driven to rise and fall by the adjustment block. When such a solution is adopted, the adjustment block slides with the device body and rises and falls along the device body, thereby driving the guide frame to rise and fall.

[0021] Furthermore, in order to improve the position recognition and alignment during spraying, the number and position of the guide cameras can be reasonably set to improve the alignment. The specific method is not limited to the only one. Here, an optimization is made and one of the feasible options is proposed: the number of the guide cameras is several and they are arranged at intervals on the guide frame, and the corresponding guide light sources are used to illuminate. When such a solution is adopted, guide cameras can be set at the edges and corners of the guide frame to perform image recognition from the side of the spraying component. The alignment effect can be improved by recognizing with multiple groups of guide cameras.

[0022] Furthermore, during long-term use, there are situations where the equipment is shut down for maintenance or intermittent operation. At this time, the glue spraying assembly needs to be maintained and maintained, which can be achieved in a variety of ways, which are not limited to the only ones: it also includes a feeding assembly for supplying glue, a glue wiping mechanism for wiping the spraying assembly, a dissolving tank structure for preventing the glue of the spraying assembly from solidifying, and a waste box for receiving discarded glue, and also includes a controller and is used to control the start and stop operation of the primer equipment. When such a solution is adopted, the feeding assembly supplies glue by air pressure; the glue wiping mechanism includes a glue wiping box body, which can lower the glue spraying valve into the box body to achieve wiping; the dissolving tank structure includes a dissolving tank for placing the head of the glue spraying part, which can avoid blockage inside the glue spraying head; the waste box is used to receive the discarded glue at the glue spraying part.

[0023] Compared with the prior art, some beneficial effects of the technical solution disclosed in the utility model include:

[0024] The utility model optimizes and improves the structure, so that the whole machine has a simple structure, is easy to maintain, and has a long service life. The whole machine replaces manual work to achieve automatic spraying. A laser detection calculation slope is set to ensure uniform spraying. Real-time detection is performed by guiding components to improve detection accuracy and avoid detection deviation caused by rapid volatilization of glue. At the same time, a larger monitoring field of view is obtained through the camera, which can automatically determine more product sizes and spraying paths and is compatible with a variety of product sizes.

[0039] The second structure of the primer equipment provided in this embodiment includes:

[0047] Preferably, in this embodiment, the height of the spray assembly 8 can be detected by a variety of schemes, which are not limited to the only one. This embodiment is optimized and adopts one of the feasible options: the height detection member 14 includes a laser sensor. When such a scheme is adopted, the laser sensor is vertically downward to detect the current height of the spray assembly 8, which is convenient for subsequent adjustment and spraying operation.

[0048] In order to better detect the spraying position and improve the accuracy of spraying, this embodiment is optimized and adopts one of the feasible options: the area array camera assembly includes a plurality of area array detection cameras 18, and the area array detection cameras 18 are illuminated by corresponding detection light sources 17.

This embodiment optimizes and adopts one of the feasible options: the guide assembly 11 includes a guide frame, and the guide camera 19 is connected and arranged on the guide frame. When such a solution is adopted, the guide frame is used for connection and fixing, providing a force point to connect the guide camera 19 and drive the guide camera 19 to move.

[0052] The structure of the guide frame is not limited by displacement, and it can be constructed in various forms, and is not limited to a single form. This embodiment is optimized and adopts one of the feasible options: the guide frame is set on the device body, and the device body is provided with an adjustment block 21, and the guide frame is driven to rise and fall by the adjustment block 21. When such a solution is adopted, the adjustment block 21 is slidably matched with the device body and rises and falls along the device body, thereby driving the guide frame to rise and fall.

The primer in the feeding component 2 is squeezed to the spraying component 8 by air pressure. When changing shifts or not being used for a long time, the head of the spraying component 8 is immersed in the dissolving liquid tank. Before use, the sprayed part is wiped by the wiping mechanism 3, and then a small amount of primer on the head is discharged from the waste box 5. After discharge, the manipulator can perform normal primer work.
