Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing equipment technology, and in particular to an auxiliary device for cleaning and maintaining the chip placement head of a chip placement machine. Background Technology

[0002] In the electronics manufacturing industry, surface mount technology (SMT) machines are key equipment for accurately mounting surface mount components onto printed circuit boards. As the core component of the SMT machine, the performance of the placement head directly affects the accuracy and efficiency of placement. During long-term use, the nozzles, vacuum lines, and other parts of the placement head will accumulate a large amount of solder dross, dust, and other impurities. These impurities will affect the adsorption performance and vacuum level of the placement head, leading to an increase in the defect rate of placement and even damage to the placement head. Therefore, cleaning and maintenance of the placement head of the SMT machine is extremely important.

[0003] Although existing pick-and-place head cleaning and maintenance devices are widely used, they still have some shortcomings and limitations. For example, existing pick-and-place head cleaning and maintenance devices do not have a clamping mechanism to fix the pick-and-place head, and cannot perform stable and comprehensive cleaning of the surface and internal details of the pick-and-place head, making it difficult to remove residual impurities and leading to an increase in the defect rate of subsequent pick-and-place operations.

[0004] Therefore, it is necessary to design an auxiliary device for cleaning and maintaining the placement head of a chip placement machine. Utility Model Content

[0005] To overcome the shortcomings of existing chip mount head cleaning and maintenance devices, which lack a clamping mechanism to fix the chip mount head and cannot perform stable and comprehensive cleaning of the surface and internal details of the chip mount head, resulting in the difficulty in removing residual impurities and leading to an increase in the defect rate of subsequent chip mount operations, this utility model provides an auxiliary device for cleaning and maintaining the chip mount head of an integrated chip mounter.

[0006] The technical solution of this utility model is: an auxiliary device for cleaning and maintaining the placement head of a chip mounter, comprising a housing, a power connector, a sealing cover, a water pump, a water supply pipe, a nozzle, a filter frame, a control panel, an anti-slip block, columns, clamps, and springs. The power connector is installed inside the housing. A sealing cover is slidably connected to the top of the housing. Water pumps are symmetrically distributed front and back inside the housing, each connected to a water supply pipe that passes through and is fixedly connected to the housing. A nozzle is installed at the other end of each water supply pipe. A filter frame is fixedly connected to the top left end of the housing. A control panel is installed on the left side of the housing. The water pumps are electrically connected to the control panel. An anti-slip block is fixedly connected to the top of the housing. Columns are fixedly connected to both the front and rear sides of the anti-slip block. A clamp is slidably connected between the two columns, and a spring connects the columns and the clamp.

[0007] As an improvement to the above solution, it also includes a water collection frame and a handle. The water collection frame is slidably connected to the lower left side of the housing and is located directly below the filter frame. A handle is fixedly connected to the left side of the water collection frame.

[0008] As an improvement to the above solution, a filter screen is also included, with symmetrically distributed filter screens fixedly connected to the lower ends of both the front and rear sides of the housing.

[0009] As an improvement to the above solution, it also includes a protective cover, a glass plate, and a pull rod. The protective cover is rotatably connected to the top of the housing, the glass plate is fixedly connected to the protective cover, and the pull rod is fixedly connected to the lower left side of the protective cover.

[0010] As an improvement to the above solution, it also includes magnets. A magnet is fixedly connected to the bottom left side of the protective cover, and a magnet is also fixedly connected to the top left end of the housing. The two magnets are magnetically engaged.

[0011] As an improvement to the above scheme, it also includes a compressor, a gas supply pipe and a one-way valve. Compressors are installed symmetrically on both the front and rear sides inside the housing. The control panel is electrically connected to the compressor. Each compressor is connected to a gas supply pipe, which passes through the housing and is fixedly connected to it. The other end of each gas supply pipe is connected to a water supply pipe. A one-way valve is installed on the gas supply pipe.

[0012] Beneficial effects: 1. By manually lifting the clamping block upwards and sliding it upwards on the column, the spring is compressed. After placing the patch head in the center of the anti-slip block, the clamping block is released, and the spring returns to its original position, pushing the clamping block downwards to fix the patch head. This solves the problem that existing patch head cleaning and maintenance devices lack a clamping mechanism to fix the patch head, making it impossible to perform stable and comprehensive cleaning of the surface and internal details of the patch head, resulting in the difficulty in removing residual impurities and leading to an increase in the defect rate of subsequent patching operations.

[0013] 2. This utility model is equipped with a compressor, an air supply pipe and a one-way valve. When the compressor starts, it generates compressed air, which is delivered to the water supply pipe through the air supply pipe. The one-way valve can prevent the cleaning liquid from flowing back into the compressor, ensuring that the gas flows only towards the nozzle. The compressed air and the cleaning liquid mix in the water supply pipe and are sprayed out in a high-pressure form to form a high-speed water flow. Attached Figure Description

Detailed Implementation

[0018] Example: An auxiliary device for cleaning and maintaining the placement head of a chip mounter, such as... Figures 1-4 As shown, the device includes a housing 1, a power connector 101, a sealing cover 2, a water pump 3, a water supply pipe 4, a nozzle 5, a filter frame 6, a control panel 7, an anti-slip block 18, a column 19, a clamping block 20, and a spring 21. The power connector 101 is installed inside the housing 1. The sealing cover 2 is slidably connected to the top of the housing 1. Water pumps 3 are symmetrically distributed front and back inside the housing 1. Each water pump 3 is connected to a water supply pipe 4, which penetrates the housing 1 and is welded to it. A nozzle 5 is installed at the other end of each water supply pipe 4. The top of the housing 1... A filter frame 6 is welded to the left end. The filter frame 6 can intercept large particulate impurities (such as solder dross and metal shavings) in the cleaning waste liquid. A control panel 7 is installed on the left side of the housing 1. The water pump 3 is electrically connected to the control panel 7. An anti-slip block 18 is welded to the top of the housing 1 to prevent the patch head from sliding under the impact of the cleaning water flow. It forms a double fixation with the clamping block 20. Columns 19 are welded to both the front and rear sides of the anti-slip block 18. The clamping block 20 is slidably connected between the two columns 19. A spring 21 is connected between the columns 19 and the clamping block 20.

[0019] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a water collection frame 8 and a handle 9. The water collection frame 8 is slidably connected to the lower left side of the housing 1. The water collection frame 8 is located directly below the filter frame 6 and is used to collect waste liquid. The handle 9 is welded to the left side of the water collection frame 8.

[0020] like Figures 1-4 As shown, it also includes a filter screen 10, a protective cover 11, a glass plate 12, a pull rod 13, and a magnet 14. The lower ends of the front and rear sides of the housing 1 are welded with symmetrically distributed filter screens 10, which can realize heat dissipation of the internal components of the housing 1 and avoid overheating of the equipment due to long-term operation. The protective cover 11 is rotatably connected to the top of the housing 1, and a glass plate 12 is welded on the protective cover 11. The operator can observe the cleaning process through the glass plate 12 without frequently opening the protective cover 11. A pull rod 13 is welded to the lower left side of the protective cover 11, and a magnet 14 is welded to the bottom left side of the protective cover 11. A magnet 14 is also welded to the top left end of the housing 1. The two magnets 14 cooperate magnetically to enhance the sealing effect.

[0021] like Figure 2 and Figure 4 As shown, it also includes a compressor 15, an air supply pipe 16, and a one-way valve 17. The compressors 15 are symmetrically distributed on both the front and rear sides of the housing 1. The control panel 7 is electrically connected to the compressors 15. Each compressor 15 is connected to an air supply pipe 16. The air supply pipe 16 passes through the housing 1 and is welded to it. The other end of each air supply pipe 16 is connected to a water supply pipe 4. A one-way valve 17 is installed on the air supply pipe 16 to prevent the cleaning liquid from flowing back into the compressor 15 and to ensure that the gas flows only in the direction of the nozzle 5.

[0022] When cleaning and maintenance of the placement head of the integrated placement machine is required, overcome the magnetic force between the magnets 14, pull the lever 13 to rotate the protective cover 11 to open the housing 1, manually lift the clamp 20 upwards and slide it upwards on the column 19. The spring 21 is compressed. Place the placement head in the center of the anti-slip block 18 and then release the clamp 20. The spring 21 returns to its original position and pushes the clamp 20 downwards, thereby fixing the placement head. Connect the placement head to the power connector 101 for subsequent cleaning. The anti-slip block 18 can prevent the placement head from sliding during the cleaning process. Then rotate the protective cover 11 to close the housing 1. The two magnets 14 attract each other again to form a closed space. The operator can observe the cleaning process through the glass plate 12. Next, lift the sealing cover 2 to open the housing 1, pour the cleaning solution into the housing 1, and then put the sealing cover 2 back to close the housing 1. The water pump 3 and compressor 15 can then be started through the control panel 7. The water pump 3 draws the cleaning solution out of the housing 1 and delivers it to the nozzle 5 through the water pipe 4. The compressor 15 starts to generate compressed air, which is delivered to the water pipe 4 through the air supply pipe 16. The one-way valve 17 prevents the cleaning fluid from flowing back into the compressor 15, ensuring that the gas flows only towards the nozzle 5. The compressed air and the cleaning fluid mix in the water pipe 4 and are sprayed out in the form of high pressure to form a high-speed water flow, which washes away the solder slag, dust and other impurities on the surface of the chip head. The waste liquid after rinsing carries the impurities through the filter frame 6. After filtering out large particles of impurities, it falls into the water collection frame 8 below the housing 1. The filter screen 10 can dissipate heat to prevent the internal components of the housing 1 from overheating due to long-term operation. After cleaning, the water pump 3 and the compressor 15 are turned off, the housing 1 is opened, the connection between the chip head and the power connector 101 is disconnected, the clamp 20 is lifted to remove the cleaned chip mounter, the clamp 20 is released, and the impurities on the surface of the filter frame 6 are cleaned. The housing 1 can then be closed. Finally, the handle 9 is pulled to pull the water collection frame 8 off the housing 1, cleans it inside and pushes it back for subsequent use. This completes the working process of this device.
