Description

Technical Field

[0001] This utility model relates to the field of resistive element equipment technology, and in particular to a visual inspection device for resistive elements. Background Technology

[0002] A resistor is an electronic component that impedes the flow of electric current. Some types of resistors on the market are quite small, and they need to be inspected before being used in the next stage of production, either after being transported to the manufacturer or after manufacturing, to check for wear or damage.

[0003] The prior art, authorized by CN221515271U, discloses an electronic component defect detection and screening device that uses visual inspection combined with conveyor belt inspection for detection and screening. It uses push rods for differentiation. However, since the conveyor belt is continuously transmitting, there may be components that cannot be separated in time after detection and identification. At the same time, the unloading unit also needs to position the loaded components to accurately unload them. This process is time-consuming and has low positioning accuracy.

[0004] Therefore, it is necessary to design a visual inspection device for resistive elements to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a visual inspection device for resistive elements to overcome the aforementioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A visual inspection device for resistive elements includes a frame and a storage unit disposed on the frame platform. The device further includes a material holding unit disposed next to the storage unit for storing defective resistive elements.

[0008] A robotic arm module detects resistive elements on a storage unit and picks up defective resistive elements from the storage unit onto a bonding unit; the robotic arm module includes a multi-axis robotic arm, a mounting base disposed at the drive end of the robotic arm, a vision inspection unit disposed at one end of the mounting base for detecting resistive elements, and a pick-up unit disposed at the other end of the mounting base for picking up resistive elements.

[0009] The suction unit includes a suction mounting block mounted on the mounting base, a vacuum adsorption mounting block mounted on the suction mounting block by a fastener, and a vacuum adsorption head that can move up and down and is partially installed in the vacuum adsorption mounting block.

[0010] Preferably, a quick connector is also provided on the mounting base.

[0011] Preferably, a limiting platform is provided on a portion of the vacuum adsorption head that is not placed inside the vacuum adsorption mounting block, and a spring is sleeved on the outer side of the end of the vacuum adsorption head that is not placed inside the vacuum adsorption mounting block, with one end of the spring abutting against the limiting platform and the other end abutting against the bottom surface of the vacuum adsorption mounting block.

[0012] Preferably, a connector is provided on the top of the vacuum adsorption mounting block.

[0013] Preferably, the storage unit includes a flexible vibrating plate and a material tray detachably mounted on the flexible vibrating plate.

[0014] Preferably, the tray is surrounded by a barrier.

[0015] Preferably, the adhesive unit includes a support and an adhesive plate disposed on the support.

[0016] Preferably, the adhesive plate is provided with several layers of adhesive films stacked together.

[0017] The beneficial effects of this utility model are: This technical solution installs the visual inspection unit and the suction unit on the same set of mounting bases, which can realize rapid visual inspection and remove defective products as soon as possible. This design not only saves time and speeds up the cycle, but also, since the positional relationship between the two is fixed, after the defective product is detected, the control system positions it and the robotic arm drives the picking unit to accurately pick up the defective product.

[0018] The flexible vibratory feeder is used in conjunction with the vision inspection unit and the suction unit. The vibration function of the flexible vibratory feeder is used to adjust the position of the resistive elements in the feeder, thereby achieving comprehensive inspection with an accuracy of at least 95%.

Detailed Implementation

[0024] Reference Figures 1 to 4 A visual inspection device for resistive elements includes a device frame 1, a storage unit 2 disposed on the platform of the device frame 1, a bonding unit 3 disposed next to the storage unit 2, and a robotic arm module 4 for detecting resistive elements on the storage unit 2 and picking up defective resistive elements on the storage unit 2 and transferring them to the bonding unit 3.

[0025] The robotic arm module 4 includes a multi-axis robotic arm 41, a mounting base 42 disposed at the driving end of the robotic arm 41, a vision inspection unit 43 disposed at one end of the mounting base 42 for detecting resistive elements, and a suction unit 44 disposed at the other end of the mounting base 42 for picking up resistive elements. By disposing of the suction unit 44 and the vision inspection unit 43 on the same mounting base 42, the two units can be driven simultaneously when driven by the robotic arm 41, thereby achieving simultaneous vision inspection and suction. Since the suction unit 44 and the vision inspection unit 43 are disposed on the same mounting base 42, their spacing and position are fixed. Therefore, after the vision inspection unit 43 detects a defective product, it is convenient to transmit the information to the control system, and the system can be directly driven according to the position and spacing. Compared with the prior art, it is not necessary to calculate the entire plane, thereby improving the accuracy of movement and ensuring that the suction unit 44 picks up defective products.

[0026] In order to enable quick installation with the robot arm 41, a quick connector 45 is also provided on the mounting base 42. The quick connector can be a threaded connector, a pin connection, or other quick connection structure.

[0027] The visual inspection unit 43 includes a visual verification camera 432 mounted on the mounting base 42 via a mounting block 431, and an illumination light source 434 disposed at the front end of the lens of the visual verification camera 432 via a connecting rod 433; the visual verification camera 432 identifies the resistive elements on the storage unit 2, and simultaneously transports the defective resistive elements to the control system, which controls the robotic arm to drive the suction unit 44 to remove the defective products.

[0028] The suction unit 44 includes a suction mounting block 441 mounted on the mounting base 42, a vacuum adsorption mounting block 443 mounted on the suction mounting block 441 by a fastener 442, and a vacuum adsorption head 444 that can move up and down and is partially installed in the vacuum adsorption mounting block 443. By setting the vacuum adsorption head 444 that can move up and down, when it comes into contact with the resistive element, it will not make hard contact but will have a certain compression, thereby ensuring that the electronic component will not be damaged secondary.

[0029] A limiting stage 445 is provided on the part of the vacuum adsorption head 444 that is not placed inside the vacuum adsorption mounting block 443, and a spring 446 is sleeved on the outer side of the end of the vacuum adsorption head 444 that is not placed inside the vacuum adsorption mounting block 443. One end of the spring 446 abuts against the limiting stage 445, and the other end abuts against the bottom surface of the vacuum adsorption mounting block 443. When the vacuum adsorption head 444 is squeezed and retracted, the spring 446 resets the vacuum adsorption head 444 after the squeezing is released.

[0030] A connector 447 is provided on the top of the vacuum adsorption mounting block 443. This connector 447 is used to connect to an external air pressure system. The air pressure system provides adsorption force, and the air pressure connects to the vacuum adsorption head 444, so that the end of the vacuum adsorption head 44 has adsorption force, which can pick up and remove the resistive element.

[0031] The storage unit 2 includes a flexible vibrating plate 21 and a detachable tray 22 mounted on the flexible vibrating plate. The continuous vibration of the flexible vibrating plate 21 causes the resistive elements placed in the tray 22 to jump and flip over, which is then detected by the visual inspection unit 43 to check the resistive elements. The detachable tray 22 is for easy removal after inspection, and the inspected resistive elements in the tray 22 can be directly recycled.

[0032] The material tray 2 is surrounded by a barrier to increase the height of the material tray 2 and prevent resistance atoms from flying out during vibration.

[0033] The adhesive unit 3 includes a support 31 and an adhesive plate 32 disposed on the support 31; defective resistive elements are picked up and placed on the adhesive plate 32 for recycling;

[0034] The adhesive plate 32 is provided with multiple layers of adhesive film. Depending on the usage time, the film with insufficient adhesion can be removed and replaced with a new film for continued use.

[0035] The equipment frame 1 also houses a control system for controlling the storage unit 2 and the robotic arm module 4. This control system can be a remote I / O system, meaning it remotely controls the input and output of the equipment. While sensors and actuators are typically directly connected to the control system, in a remote I / O system, these devices are connected to a remote controller via a communication network. This allows for efficient data transmission and equipment control even when the equipment and controller are geographically distant. The aforementioned existing technology enables the control system to control the storage unit 2 and the robotic arm module 4, as well as receive and analyze signals.

[0036] In this implementation, the resistive elements to be tested are placed in the tray 22. Then, the flexible vibrating plate 21 is activated. The vibration of the flexible vibrating plate 21 causes the entire tray 22 and the resistive elements inside to vibrate together. The robot arm 41 drives the vision inspection unit 43 and the suction unit 44 to move synchronously to the tray 22. They move sequentially along the area inside the tray 22. The vision inspection unit 43 inspects the resistive elements to check if they are qualified. If they are qualified, it moves to continue inspection. If they are defective, the control system receives the signal and transmits the signal to the robot arm 41. The robot arm 41 is then driven to align the vacuum suction head 444 of the suction unit 44 with the defective resistive element and pick it up. After picking it up, the robot arm 41 moves to the adhesive plate 32 of the adhesive unit 3. The resistive elements contact and stick to the adhesive plate 32. The robot arm then moves back to the tray 22 for inspection. The above work is carried out synchronously and continuously until all the resistive elements in the tray are inspected. After the inspection and sorting work is completed, the tray 22 is manually removed for recycling.

[0037] The advantages of this utility model are that the visual inspection unit and the picking unit 44 are installed on the same set of mounting bases, which can realize rapid visual inspection and remove defective products in the first time. This design not only saves time and speeds up the cycle, but also, since the positional relationship between the two is fixed, after the defective product is detected, the control system will position it and the robotic arm will drive the picking unit to accurately pick up the defective product.

[0038] The flexible vibratory feeder is used in conjunction with the vision inspection unit and the suction unit. The vibration function of the flexible vibratory feeder is used to adjust the position of the resistive elements in the feeder, thereby achieving comprehensive inspection with an accuracy of at least 95%.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
