Description

Technical Field

[0001] This invention relates to the field of electronic component processing equipment technology, and more particularly to an automatic tin-dipping machine for electronic components. Background Technology

[0002] In the production of electronic components such as network transformers, automotive electronic components, and industrial transformers, tin plating is a key subsequent process. Its main functions include concealing the exposed copper wires on the product surface to prevent copper wire oxidation, extending the product's service life, smoothing the product's contact surfaces to ensure stable electrical performance when assembled or used with other components, and improving the product's appearance to meet market demands.

[0003] In existing technologies, tin plating of such electronic components is mostly done manually or with semi-automatic equipment. When done manually, workers need to manually complete a series of processes such as loading workpieces, applying flux, tinning, flattening, and unloading. This is not only labor-intensive and inefficient, but also results in poor consistency, leading to uneven tin plating thickness and inconsistent flux application, which in turn causes unstable product quality. While semi-automatic equipment reduces some manual intervention, it is mostly designed with a single or few workstations, and the connection between processes is not smooth. Manual assistance is still required for workstation switching or material transfer, making it impossible to achieve fully automated production. Furthermore, the control precision of key processing parameters such as tinning temperature and flattening pressure is insufficient, further affecting the tin plating quality of the product and making it difficult to meet the needs of mass production. Therefore, it is necessary to design an automatic tinning machine for electronic components to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic tin-dipping machine for electronic components.

The feeding station is provided with a workpiece positioning groove. A vacuum nozzle assembly is provided above the feeding station on the frame. The vacuum nozzle assembly includes a vacuum generator, a negative pressure sensor, and eight vacuum nozzles. The vacuum generator is installed on the side of the frame and connected to the eight vacuum nozzles respectively through air pipes. Each vacuum nozzle is directly below the workpiece positioning groove of the corresponding station divider. The negative pressure sensor is installed on the air pipe connecting the vacuum generator and the vacuum nozzles and is electrically connected to the control module in the control panel.

The support plate can drive the workpiece on the tin-immersion station to be immersed in the molten solder in the tin-immersion tank under the drive of the third cylinder.

[0009] Preferably, the pressing platform is fixed to the machine frame table and located directly below the flattening station. The flattening station table has a clearance hole for the pressing platform to pass through. The fourth cylinder is vertically mounted on the machine frame and located directly above the flattening station. A metal flattening block is fixed to the lower end of the piston rod of the fourth cylinder. The fifth cylinder is horizontally mounted on the machine frame and located on one side of the immersion tank. The piston rod of the fifth cylinder faces the inside of the immersion tank. The CCD mounting bracket spans above the CCD inspection station. A CCD camera and a supplementary light source are fixed at the bottom of the CCD mounting bracket. The CCD camera is electrically connected to the control module in the control panel.

[0010] Preferably, a metal scraper is fixed to the piston rod end of the fifth cylinder, the bottom of the scraper is in contact with the surface of the molten tin in the immersion tank, a slag discharge port is opened on the side wall of the immersion tank away from the fifth cylinder, and an impurity collection box is provided below the slag discharge port.

This multi-dimensional approach ensures the tin plating quality of the product and reduces the defect rate.

[0016] 4. By setting up components such as compensation stations and pusher cylinders, the compensation station can temporarily take over the workpiece when a brief abnormality occurs at any preceding station, avoiding overall production interruption.

[0029] Furthermore, the bottom of the metal flattening block is polished to ensure its surface is flat and to avoid leaving scratches on the tin layer surface of the workpiece during flattening. The CCD mounting bracket 7 is also equipped with a height adjustment mechanism, which can adjust the distance between the CCD camera and the workpiece according to the detection requirements of different specifications of workpieces, thereby improving detection accuracy.

[0030] A metal scraper is fixed to the piston rod end of the fifth cylinder 24. The bottom of the scraper is in contact with the surface of the molten tin in the immersion tank 5. A discharge port is provided on the side wall of the immersion tank 5 away from the fifth cylinder 24. An impurity collection box is provided below the discharge port. The fifth cylinder 24 can drive the scraper to reciprocate along the surface of the molten tin.

[0031] Furthermore, the metal scraper is made of corrosion-resistant material to prevent rusting from prolonged contact with molten tin. A filter screen is also provided at the impurity discharge port to preliminarily filter impurities and prevent impurity fragments from falling back into the tin immersion tank 5. The impurity collection box is detachably connected to the frame 1 for easy periodic cleaning of internal impurities.

[0032] Multiple electric heating tubes are embedded in the inner wall of the immersion tank 5. A temperature sensor is installed at the bottom of the immersion tank 5.

[0036] When using this invention, the operator starts the equipment through the control panel 8, the drive component drives the station divider 11 to operate intermittently, the feeding vibratory plate 2 transports the workpiece to be processed to the workpiece positioning slot of the feeding station 12 through the feeding track, then the first cylinder 20 drives the vacuum nozzle assembly to move down, the vacuum generator starts to generate negative pressure, the vacuum nozzle contacts the workpiece and adsorbs and fixes it, the negative pressure sensor monitors the negative pressure value in the air pipe in real time, after confirming that the adsorption is stable, the station divider 11 drives the feeding station 12 to rotate to the flux station 13; Upon reaching flux station 13, the second cylinder 21 drives the pressure block to move downwards, pressing the workpiece so that the part to be tinned is immersed in the flux in flux tank 4. After tinning, the second cylinder 21 resets, and the station divider 11 continues to rotate the workpiece to tinning station 14. At this time, the third cylinder 22 drives the support plate to rise, lifting the workpiece into the tin liquid in tinning tank 5 to complete tinning. After tinning, the third cylinder 22 drives the support plate to fall, and the station divider 11 transfers the workpiece to flattening station 15. At flattening station 15, the fourth cylinder 23 drives the metal flattening block to move downwards, cooperating with the pressing platform 6 to flatten the tin layer on the surface of the workpiece. After flattening, the fourth cylinder 23 resets, and the station divider 11 rotates the workpiece to CCD detection station 16. The supplementary light source on the CCD mounting bracket 7 is turned on, and the CCD camera collects the tin-plated appearance image of the workpiece and transmits it to the control module in the control panel 8. The control module analyzes and judges whether the workpiece is qualified. If the workpiece is a good product, the station divider 11 drives the workpiece to the good product unloading station 17. The corresponding pusher cylinder drives the pusher plate to push the workpiece to the first discharge port, and the workpiece falls into the good product collection box 9. If it is a defective product, the workpiece is transferred to the defective product unloading station 18. Another pusher cylinder drives the pusher plate to push the workpiece to the second discharge port, and it falls into the defective product collection box 10. When the empty station rotates with the station divider 11 to the compensation station 19, if the previous station has a brief abnormality, the compensation station 19 can temporarily take over the workpiece to avoid the overall production interruption. At the same time, during the operation of the equipment, the fifth cylinder 24 periodically drives the metal scraper to reciprocate along the surface of the molten tin in the immersion tank 5, pushing the impurities on the surface of the molten tin to the impurity discharge port and falling into the impurity collection box. The temperature sensor in the immersion tank 5 collects the temperature of the molten tin in real time. The control module adjusts the working status of the electric heating tube according to the temperature data to maintain the molten tin temperature stably and ensure the continuous and efficient operation of each process.
