Abstract
Description
Technical Field
[0001] This utility model relates to the field of servo control system technology, specifically to a servo control system for a dispensing machine based on an Omron PLC. Background Technology
[0002] In industries such as electronics manufacturing, dispensing adhesive onto winding coils is a common and crucial process. Traditional dispensing methods are inefficient, requiring manual handling of winding coil loading, transport, and dispensing, resulting in high labor intensity and susceptibility to human error, leading to inconsistent dispensing quality. To address these issues, those skilled in the art have explored solutions. For example, the CCD automatic loading and unloading dispensing machine (Chinese Patent Publication No. CN213558057U) uses an adsorption mechanism to pick up the workpiece and move it to a fixed mechanism. The dispensing mechanism then dispenses adhesive onto the workpiece in the fixed mechanism, after which the fixed mechanism unloads the workpiece. However, existing dispensing equipment still has shortcomings. Its functions are relatively limited, lacking integrated design, making it difficult to achieve efficient and precise dispensing of winding coils. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a servo control system for dispensing machines based on Omron PLC.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A servo control system for a dispensing machine based on an Omron PLC includes an Omron PLC controller and a robotic arm connected to the Omron PLC controller. The end effector of the robotic arm is equipped with an adsorption mechanism and a dispensing mechanism via a support frame.
[0006] The adsorption mechanism is moved to the feeding line by a robotic arm. The feeding line has winding coils arranged at intervals. The adsorption mechanism includes an electromagnet. When the electromagnet is energized, it attracts the winding coils on the feeding line.
[0007] The dispensing mechanism moves to the unloading line via a robotic arm. The unloading line has fixed fixtures arranged at intervals, and the fixtures have magnets that attract the winding coils. The dispensing mechanism includes a dispensing cylinder, as well as hydraulic pistons and dispensing needles located on both sides of the dispensing cylinder. The hydraulic pistons squeeze the adhesive in the dispensing cylinder and apply it to the winding coils through the dispensing needles.
[0008] This technical solution utilizes a robotic arm integrating an adsorption mechanism and a dispensing mechanism to perform dispensing on wound coils, improving dispensing efficiency. Specifically, the unloading line is equipped with a fixed fixture that works with the wound coils. Magnets on the fixture ensure that the wound coils do not shift during the dispensing process. The adsorption mechanism is also a specially designed electromagnet for adsorbing the wound coils; conventional suction heads and grippers have limited adsorption effects on wound coils. The dispensing mechanism is arranged vertically, allowing for dispensing at multiple angles on wound coils of different depths, and it has its own dispensing cylinder, meeting the needs of mass production.
[0009] In addition, the Omron PLC-based servo control system for the dispensing machine proposed above can also have the following additional technical features:
[0010] According to one embodiment of the present invention, the fixing fixture is arranged in a column shape, and a ring of magnets matching the winding coil is arranged around its periphery.
[0011] In this technical solution, the magnets are arranged in a matrix around the fixed fixture, which can evenly attract the winding coil and avoid bumps and damage.
[0012] According to one embodiment of the present invention, the dispensing cylinder is connected to the colloid storage tank via a pipeline, and a dispensing valve is installed on the pipeline, which is connected to an Omron PLC controller.
[0013] In this technical solution, the colloid storage tank is externally mounted on an Omron PLC controller. By opening and closing the dispensing valve, the suction mechanism can be driven to supply colloid to the dispensing cylinder.
[0014] According to one embodiment of the present invention, the dispensing mechanism is hinged to one side of the support below the robotic arm and rotates 90° relative to the support.
[0015] In this technical solution, the dispensing mechanism is too long. During the feeding process, the dispensing mechanism can be folded or extended outward by rotating 90° to avoid affecting the movement of the adsorption mechanism.
[0016] According to one embodiment of the present invention, both the electromagnet and the hydraulic piston are connected to an Omron PLC controller.
[0017] In this technical solution, the Omron PLC controller achieves energy saving and the attraction of the winding coil through the switching of the electromagnet; the Omron PLC controller starts the hydraulic piston, and through the extension and retraction of the piston, the adhesive in the dispensing cylinder is squeezed downward, so as to be evenly coated through the dispensing needle.
[0018] According to one embodiment of the present invention, both the loading and unloading production lines are equipped with drive motors, which are connected to Omron PLC controllers. When the dispensing mechanism is working, the loading and unloading production lines are in a paused state.
[0019] In this technical solution, in order to minimize interference during the dispensing process, the loading and unloading lines are paused. Once the dispensing is complete, the loading and unloading lines resume transmission.
[0020] Compared with the prior art, this utility model has the following advantages:
[0021] By using a robotic arm that integrates an adsorption mechanism and a dispensing mechanism, the dispensing efficiency of the winding coil is improved. Attached Figure Description

[0030] The dispensing mechanism 7 moves to the unloading line 1 via the robotic arm 5. The unloading line 1 is equipped with fixed fixtures 2 arranged at intervals. The fixed fixtures 2 have magnets that attract the winding coils 4. The dispensing mechanism 7 includes a dispensing cylinder, as well as hydraulic pistons and dispensing needles 8 located on both sides of the dispensing cylinder. The hydraulic piston squeezes the adhesive in the dispensing cylinder and applies it to the winding coils 4 through the dispensing needles 8.
[0031] like Figures 1 to 3 As shown, this technical solution utilizes a robotic arm 5 integrating an adsorption mechanism 6 and a dispensing mechanism 7 to perform dispensing on the winding coil 4, thereby improving dispensing efficiency. Specifically, the unloading line 1 is equipped with a fixed fixture 2 that cooperates with the winding coil 4. The magnet on the fixed fixture 2 ensures that the winding coil 4 does not shift during the dispensing process.

[0034] In this technical solution, the magnets are arranged in a matrix around the fixed fixture 2, which can evenly attract the winding coil 4 and avoid bumping and damage.

[0036] In this technical solution, the colloid storage tank is externally mounted on an Omron PLC controller. By opening and closing the dispensing valve, the suction mechanism can be driven to supply colloid to the dispensing cylinder.
[0037] According to one embodiment of the present invention, the dispensing mechanism 7 is hinged to one side of the support below the robotic arm 5 and rotates 90° relative to the support.
[0038] In this technical solution, the dispensing mechanism 7 is too long. During the feeding process, the dispensing mechanism 7 can be folded or extended outward by rotating 90° to avoid affecting the movement of the adsorption mechanism 6.
[0039] According to one embodiment of the present invention, both the electromagnet and the hydraulic piston are connected to an Omron PLC controller.
[0040] In this technical solution, the Omron PLC controller achieves energy saving and attraction of the winding coil 4 by switching the electromagnet; the Omron PLC controller starts the hydraulic piston, and through the extension and retraction of the piston, the adhesive in the dispensing tube is squeezed downward, so that it is evenly coated through the dispensing needle 8.

[0043] The usage process of the above embodiments is as follows:
[0044] like Figures 1 to 3 As shown, firstly, the robotic arm 5 drives the adsorption mechanism 6 to the feeding line 3, and the electromagnet is energized to attract the winding coil 4; then, the robotic arm 5 drives the adsorption mechanism 6 to rotate 180°, placing the winding coil 4 onto the fixed fixture 2 on the unloading line 1; the fixed fixture 2 is columnar with a matrix of magnets around its periphery, which can evenly attract the coil and prevent displacement and damage; the robotic arm 5 drives the dispensing mechanism 7 to rotate 180°, and the dispensing mechanism 7 is aligned with the winding coil 4; the dispensing cylinder is connected to the glue storage tank through a pipeline, and the dispensing valve is controlled by an Omron PLC controller to supply glue as needed; during dispensing, the hydraulic piston squeezes the glue in the dispensing cylinder and applies it to the coil through the dispensing needle 8; the dispensing mechanism 7 can be hinged and rotated 90°, folding or expanding during feeding to avoid interfering with the adsorption mechanism 6.
