Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning equipment for SMT fixtures. Background Art

[0002] An SMT jig is a tool specifically designed to assist in positioning and supporting electronic components during the SMT production process. It ensures that components are accurately and stably placed on the PCB (printed circuit board) before soldering, thereby improving production efficiency and product quality. As an important auxiliary tool on the SMT production line, the cleanliness of the SMT jig directly affects the placement quality of electronic components and product reliability, making it essential to clean the SMT jig.

[0003] Currently, when cleaning SMT jigs, high-pressure water jet equipment is used to clean the SMT jigs. However, during the cleaning process, the high-pressure water jet equipment cannot directly and comprehensively rinse the SMT jigs, and workers are required to flip the SMT jigs multiple times for cleaning. The cleaning efficiency is low and the cleaning effect is poor. In view of this, we propose an SMT jig cleaning device. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] This embodiment provides a technical solution:

[0029] See also Figure 1-Figure 5As shown, a cleaning device for SMT jigs includes a water tank 1 with an opening at the top, a water supply pipe 11 is installed at the top opening of the water tank 1, and the water supply pipe 11 is in a U-shaped shape. A plurality of nozzles 12 are installed on the upper and lower side walls of the opening of the water supply pipe 11, and a water inlet pipe 13 passing through the water tank 1 is installed at the front end of the water supply pipe 11; a rotating shaft 14 is rotatably installed at both ends of the interior of the water tank 1, a sprocket 15 is coaxially keyed to the center of the rotating shaft 14, and a chain 16 is engaged between the two sprockets 15; a first motor 17 for driving the rotating shaft 14 to rotate is installed on the front face of the water tank 1; a jig carrying part 2 that can move horizontally is provided above the chain 16, and the jig carrying part 2 includes two symmetrical brackets 20, and the brackets The bottom end of 20 is fixedly connected to the top of the chain 16 by bolts, and a double-headed screw 22 is rotatably installed at the bracket 20 on the right, and a second motor 23 for driving the double-headed screw 22 to rotate is installed on the front end face of the bracket 20; a guide rod 26 is fixed at the bracket 20 on the left; two symmetrical clamping seats 24 are provided between the double-headed screw 22 and the guide rod 26, and the right end of the clamping seat 24 is threadedly connected to the thread grooves at both ends of the double-headed screw 22, and the left end of the clamping seat 24 is passed through by the guide rod 26 and is slidably connected to the guide rod 26, and the two clamping seats 24 both pass through the opening of the water supply pipe 11; a plurality of brackets 25 for carrying and clamping SMT fixtures are fixed near the left end on the two opposite end faces of the two clamping seats 24.

[0030] In this embodiment, the overall shape of the bracket 25 is L-shaped, and the bracket 25 is fixedly connected to the clamping base 24 by bolts. The L-shaped design facilitates the bracket 25 to support the SMT fixture, and the bolt fixing method ensures the installation reliability of the bracket 25.

[0031] In this embodiment, the overall shape of the bracket 20 is U-shaped and the bracket 20 is made of stainless steel. The U-shape facilitates the installation of the double-ended screw 22 and the guide rod 26. The stainless steel material is corrosion-resistant, ensuring the service life of the bracket 20.

[0032] In this embodiment, two guide connecting rods 18 are bolted into the inner cavity of the water tank 1. Two connecting blocks 21 are fixed to the bottom of the bracket 20. The connecting rods 18 pass through the connecting blocks 21 and are slidably connected to the connecting blocks 21. The provision of the connecting rods 18 guides the horizontal movement of the bracket 20, ensuring smooth and stable movement of the bracket 20.

[0033] In this embodiment, the overall shape of the water inlet pipe 13 is Z-shaped, and the water inlet pipe 13 is fixedly connected to the water supply pipe 11 via a flange. The Z-shaped arrangement facilitates the water inlet pipe 13 to supply water to the water supply pipe 11.

[0034] In this embodiment, the upper and lower nozzles 12 are positioned opposite each other, and the nozzles 12 on the same horizontal plane are linearly and evenly spaced. This design facilitates comprehensive cleaning of the SMT jig by the upper and lower nozzles 12, and the provision of multiple nozzles 12 improves cleaning efficiency.

[0035] In this embodiment, the threads at both ends of the double-ended screw 22 are wound in opposite directions, and the ends of the double-ended screw 22 are rotatably connected to the inner wall of the bracket 20 via bearings. When the double-ended screw 22 rotates, the clamping seats 24 on both sides can move synchronously with each other, and the bearings support and enable the rotation of the double-ended screw 22, ensuring the stability of the double-ended screw 22.

[0036] In this embodiment, a drain outlet 10 is installed at the lower part of the left end surface of the water tank 1, and a plug is installed at the drain outlet 10. The setting of the drain outlet 10 is convenient for draining sewage, and the setting of the plug is convenient for controlling drainage.

[0037] It should be added that the first motor 17 in this embodiment is a waterproof motor. When cleaning the SMT jig, some water stains will splash onto the first motor 17, and the first motor 17 has a waterproof effect, thereby ensuring the stability of use of the first motor 17.

[0038] It is worth noting that the first motor 17 and the second motor 23 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0039] Before use, the user first places the SMT jig between the multiple brackets 25 on both sides. Then, the user turns on the power of the second motor 23, and the second motor 23 starts to work. The output shaft of the second motor 23 rotates to drive the double-headed screw 22 to rotate. As the double-headed screw 22 rotates, the two clamping seats 24 move inward relative to each other synchronously. When the brackets 25 on both sides clamp the SMT jig, the user turns off the power of the second motor 23.

[0040] During specific use, the user first connects the water inlet pipe 13 to the power supply, and the water source enters the water supply pipe 11 through the water inlet pipe 13. At the same time, the water source is sprayed out through multiple nozzles 12. Then the user turns on the power of the first motor 17, and the first motor 17 starts to work. The output shaft of the first motor 17 rotates to drive the rotating shaft 14 to rotate, and the rotating shaft 14 drives the sprocket 15 to rotate. Because the sprocket 15 is engaged with the chain 16, the chain 16 moves between the two sprockets 15. At the same time, the chain 16 drives the bracket 20 to move horizontally. At this time, the bracket 20 drives the clamping seat 24 and the SMT fixture to move horizontally. At this time, the SMT fixture slowly passes through the opening of the water supply pipe 11. At this time, the water source sprayed by the nozzle 12 is sprayed on the outside of the SMT fixture. Under the spraying of the water source, the SMT fixture can be cleaned.

[0041] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
