Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a manual mounting device for polar and extremely small-sized surface mounting components. Background Art

[0002] Component placement is an important step in electronic manufacturing, usually used to attach passive components (such as resistors, capacitors, inductors, etc.) to printed circuit boards. This process involves a variety of techniques and equipment. Here are some common component placement uses and processes;

[0003] First, SMT (surface mount technology); this is the most common component placement method, which uses a printed circuit board printed with solder paste and surface mount components (SMD or SMC) with flux, and then heat is applied to melt the solder and connect the components and PCB;

[0004] Second, THT (reflow soldering technology): This is a more advanced placement technology that allows higher production efficiency and smaller component size. It is similar to SMT, but uses less material and more complex equipment.

[0005] Third, hybrid mounting technology: It combines the advantages of SMT and THT while reducing some disadvantages. For example, it can use SMT in some areas and THT in other areas;

[0006] Fourth, direct placement technology: This method is usually used for prototyping and small batch production. It involves sticking components directly to the surface of the PCB without the need for additional solder paste or other auxiliary materials;

[0007] Fifth, laser welding: This method is usually used to connect larger components, such as heat sinks or power modules. It uses a high-energy laser beam to produce local melting and firmly fix the components on the PCB.

[0008] Sixth, microwave curing: This is a method of melting solder through a high-frequency electromagnetic field without using heat. It is often used to connect small passive components such as chip resistors and capacitors.

[0009] Seventh, microwave curing and laser welding: Combining the advantages of the first two methods, higher quality connections and faster production speeds can be achieved;

[0010] Eighth, hot pressing technology: This is a traditional component installation method that deforms the metal lead by heating and inserts it into the hole of the PCB. This method is usually used in high current applications and high reliability requirements.

[0011] Ninth, ultrasonic welding: This method is similar to hot pressing, but it uses high-frequency sound waves to accelerate the heating process and reduce the thermal impact on components. This method may be more cost-effective than hot pressing in some cases.

[0012] At present, because electronic products have polar DFN0603-D extremely small surface mount components with a size of only 0.61*0.3mm, they are all SMT mounted by surface mount equipment, and cannot be mounted manually. First, extremely small components require special mounting equipment with high precision and high equipment procurement cost. The mounting equipment of many patch factories cannot meet the mounting requirements of extremely small components and cannot be mounted. Second, when extremely high-precision surface mount equipment is used for mounting, when equipment failure or equipment occupancy occurs, mounting cannot be performed, affecting product delivery. Third, when the number of samples is small, manual mounting is used instead of equipment mounting to reduce line change time. This device provides a manual mounting device for polar extremely small-sized surface mount components. Utility Model Content

[0013] The purpose of the utility model is to provide a manual mounting device for polarized extremely small-sized surface-mounted components in view of the deficiencies of the prior art, so as to solve the above-mentioned technical problems.

[0014] The embodiment of the utility model adopts the following technical scheme: it includes a workbench for placing the required equipment, a placement table for placing and processing components, a microscope imaging device for component placement, amplification and display, and a green light lighting device for illuminating the components by green light. The green light lighting device and the microscope imaging device are respectively located on the workbench, the green light lighting device is located next to the microscope imaging device, and the placement table is located on the microscope imaging device.

[0015] Furthermore, the microscope imaging device includes a microscope imaging table, a camera, a microscope and a display screen. The microscope imaging table is located on a workbench, the placement table is located on the microscope imaging table, the components can be placed in the center of the placement table for the operator to operate, the microscope is set on the microscope imaging table and the head end is facing the center of the microscope imaging table, which also means facing the center of the placement table. The camera is set on the observation end of the microscope, the display screen is set on the workbench and located next to the microscope, and the display screen is facing the center of the placement table. The camera is electrically connected to the display screen, and the camera can use the microscope to photograph and enlarge the components on the placement table and display and observe them through the display screen.

[0016] Furthermore, the green light lighting device includes a lighting base, a lighting board, a fixed block, an adjustment knob and a green light lighting lamp. The lighting base is arranged on the workbench and is located next to the microscope imaging table. The lighting board is arranged on the lighting base. Two fixed blocks are provided. The two fixed blocks are symmetrically arranged at the side ends of the lighting board and are located on the side facing the placement table. The adjustment knob is threadedly connected to the two fixed blocks, and the green light lighting lamp is sleeved on the adjustment knob and is fixedly connected.

[0017] Furthermore, the lower end of the placement table has a certain degree of adsorption magnetism.

[0018] Furthermore, the upper end of the placement table has a certain degree of flatness and smoothness.

[0019] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0020] The utility model can take pictures of polar and extremely small components, enlarge them, and find the required component status through the imaging on the display, so as to facilitate the operator to perform manual placement, improve the accuracy of processing, and avoid the situation that the components are extremely small and cannot be manufactured. If the components are extremely small and operated in an automated manner, it is easy to cause damage to the product and the automated processing cost is high.

[0021] The extremely small components of this device require special mounting equipment with high precision and high equipment procurement cost. The mounting equipment of many chip factories cannot meet the mounting requirements of extremely small components and cannot be mounted;

[0022] If a highly accurate surface mount device is used to mount components, if the device fails or is occupied, the mounting cannot be performed, affecting product delivery. Therefore, this device provides a precise mounting method for manual mounting, which solves this problem.

[0023] When the number of samples is small, manual placement can be used instead of equipment placement. In order to reduce line change time, manual placement methods can also be used for processing, which not only improves production efficiency but also reduces costs, making it easier to use.

[0034] The device can take pictures of polar and extremely small components, enlarge them, and find the required component status through the image on the display, so as to facilitate the operator to carry out manual placement, improve the accuracy of processing, and avoid the problem that the components are extremely small and cannot be manufactured. If the components are extremely small and operated in an automated manner, it is easy to cause damage to the product and the automated processing cost is high;

[0035] The extremely small components of this device require special mounting equipment with high precision and high equipment procurement cost. The mounting equipment of many chip factories cannot meet the mounting requirements of extremely small components and cannot be mounted;

[0036] If a highly accurate surface mount device is used to mount components, if the device fails or is occupied, the mounting cannot be performed, which affects product delivery. Therefore, this device provides a precise mounting method for manual mounting.

[0037] When the number of samples is small, manual placement can be used instead of equipment placement. In order to reduce line change time, manual placement methods can also be used for processing, which not only improves production efficiency but also reduces costs, making it easier to use.

[0039] When manually mounting polar and extremely small-sized products, firstly, the camera 22 is turned on and the focal length of the microscope 23 is adjusted to a suitable state for the required processing. At this time, the display screen 24 is in a display state through the camera 22 and the microscope 23. Then, the green light is turned on and aimed at the center of the placement table 11. At this time, the operator can place the required processed product at the center of the placement table 11. After the placement is completed, the required processed product is finally magnified through observation and photography of the camera 22 and the microscope 23, and then the green light is turned on and aimed at the center of the placement table 11. The display is displayed on the display screen 24, and the operator can use the magnified state on the display screen 24 to provide the necessary tools such as handheld tweezers to mount the required products. The whole process is simple to operate, and it is possible to photograph and magnify the polar and extremely small-sized components, and find the required component status through the imaging on the display, so as to facilitate the operator to perform manual mounting, improve the accuracy of processing, and avoid the situation where the components are extremely small and cannot be manufactured. Because the components are extremely small, if they are operated in an automated manner, it is easy to cause damage to the products and the cost of automated processing is high.

[0041] When manually mounting polar and extremely small-sized products, the operator can rotate the adjustment knob 34 to drive the green light lamp 35 to rotate, thereby adjusting the lighting angle of the green light lamp 35 so that the lighting source of the green light lamp 35 is concentrated on the center of the placement table 11, thereby facilitating the operator to better observe and operate the processing, thereby improving the processing quality.

[0042] In a further preferred embodiment of the utility model, the lower end of the placement table 11 has a certain adsorption magnetism, and the lower end of the placement table 11 has a certain adsorption magnetism, which can achieve an anti-slip effect when the operator is working, and the upper end of the placement table 11 has a certain flatness and smoothness, and the upper end of the placement table 11 has a certain flatness and smoothness, which can reduce the unevenness and other problems that may occur in the mounting process when the operator is working.
