Description

Technical Field

[0001] This utility model relates to the field of automatic alignment technology for pad printing machines, and in particular to an automatic alignment device for the feeding mechanism of a pad printing machine. Background Technology

[0002] Pad printing machines are devices that transfer patterns or text from a printing plate to a substrate using a transfer printing method. They are used for printing on various material surfaces, such as plastics, glass, metals, and sheets. The biggest advantages of pad printing machines are high printing accuracy, high speed, and wide applicability, which makes them widely used in industrial production. Because pad printing machines require high printing accuracy, and human eyes can make mistakes that cannot meet the requirements, automatic alignment equipment has been developed.

[0003] Automatic alignment equipment can automatically adjust and precisely align the positional relationship between workpieces and equipment. This device plays a crucial role in robot loading and unloading operations. It can not only quickly and accurately identify the position and posture of the workpiece, but also achieve seamless docking between the workpiece and equipment through sophisticated algorithms and mechanical structures. Early automatic alignment equipment consisted of a basic mechanical frame, drive device, and positioning components. However, due to limitations in technology and component precision, the alignment accuracy of early automatic alignment equipment was not high. To solve the problem of low alignment accuracy, current automatic alignment equipment on the market has installed laser displacement sensors, which can quickly and accurately measure the position and distance of objects and monitor changes in the position of objects in real time, providing accurate data for alignment control. However, since the objects may deviate during loading, alignment deviations still occur, making it impossible to accurately align the objects with the pad printing machine. This affects the printing quality and production efficiency of the products and wastes materials. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic alignment device for the feeding mechanism of a pad printing machine, which aims to improve the problem in the prior art where the object deviates during feeding, resulting in alignment errors and making it impossible to accurately align the object with the pad printing machine.

[0010] As a further description of the above technical solution:

[0011] Multiple iron plates are fixedly connected to the bottom of the outer wall of the pad printing equipment, and tripods are fixedly connected to the front and back sides of the multiple iron plates.

[0012] As a further description of the above technical solution:

[0013] A start switch is fixedly connected to the front end of the outer wall of the pad printing equipment. The start switch is electrically connected to the servo motor, the conveying equipment, the electric telescopic rod, and the pad printing equipment.

[0014] As a further description of the above technical solution:

[0015] A collection box is fixedly installed on the inner wall of the rear support shell, and a handle is fixedly connected to the middle of the outer wall of the collection box.

[0016] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the operator places the sheet material onto the conveying equipment, which moves the sheet material to the center of the fixed frame via a conveyor belt. The electric telescopic rods on both sides of the fixed frame extend. When the electric telescopic rods extend, the fixed plate on the electric telescopic rod approaches the sheet material. The sponge pad on the fixed plate first contacts the sheet material to reduce friction and protect the sheet material. The sliding groove restricts the rotation of the sliding block. When the threaded rod is rotated, the sliding block will drive the plug strip to move and lock into the circular groove of the fixed plate to complete the fixation. Reverse rotation will disassemble the sheet material. After the sheet material is fixed, the pad printing equipment starts the pad printing head to transfer the pattern, so that the sheet material is printed and becomes a finished product, thereby improving the alignment accuracy of the device and the ability to disassemble quickly.

[0022] 2. In this utility model, by starting the servo motor, the servo motor rotates and drives the rolling brush to rotate, thereby cleaning the surface of the conveying equipment. At the same time, the external water source is manually opened, and water flows into the water pipe and enters the nozzle to spray and clean the conveying equipment again. Since the water flow generates pressure and impact during the conveying process, water pipe leakage may occur. At this time, the sealing ring relies on its good sealing performance to tightly fit the two ends to prevent water leakage and ensure that the water flow reaches the nozzle smoothly, thereby improving the deep cleaning effect of the device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of an automatic alignment device for a pad printing machine's feeding mechanism, comprising two support shells 1. A conveying device 3 is fixedly connected to the middle of the inner wall of each of the two support shells 1. A fixed frame 12 is fixedly connected to the top of the conveying device 3. Two electric telescopic rods 4 are fixedly connected to the left and right sides of the fixed frame 12. When a sheet is placed on the conveying device 3, the conveying device 3 can transport the sheet to the middle of the fixed frame 12. At this time, the electric telescopic rods 4 on the fixed frame 12 will clamp the sheet. A connecting shell 5 is fixedly connected to an adjacent end of each of the two electric telescopic rods 4. Multiple threaded rods 8 are rotatably connected inside the connecting shell 5. Sliding blocks 9 are threadedly connected to the outer wall of each of the multiple threaded rods 8. Inserted strips 10 are fixedly connected to the front and rear sides of each sliding block 9. When the threaded rod 8 is rotated, it will drive the sliding block 9 on the threaded rod 8 to move back and forth. When the sliding block 9 moves, the inserted strip 10 will also move simultaneously. Two sliding grooves 21 are opened on an adjacent side of each of the two connecting shells 5. The opposite sides of the multiple sliding blocks 9 are slidably connected to the corresponding sliding grooves 21. The sliding groove 21 restricts the rotation of the sliding block 9. Fixed plates 6 are fixedly connected to the left and right sides of both connecting shells 5. Circular grooves 11 are provided on the front and rear sides of the fixed plates 6. The front and rear ends of the insert strip 10 engage with the circular grooves 11. When the insert strip 10 on the sliding block 9 moves horizontally, it engages with the circular grooves 11, thus fixing the fixed plates 6 and allowing for quick disassembly and replacement. A pad printing device 13 is provided on the right side of the conveying device 3. The sheet material is conveyed to the middle fixed frame 1 of the fixed frame 12. The electric telescopic rod 4 on the 2nd plate clamps the plate and fixes it in place. Then, the pad printing equipment 13 starts working and prints the pattern onto the plate, forming a finished product. The inner wall of the rear support shell 1 is equipped with a cleaning mechanism 2, which is used to improve the cleanliness of the equipment and the quality of the product. The left and right sides of the two fixed plates 6 are fixedly connected with sponge pads 7. The sponge pads 7 are semi-circular in shape. The sponge pads 7 can reduce the friction when the plate is clamped by the electric telescopic rod 4, so that the plate is minimally damaged when it is clamped.

[0033] Specifically, when the operator places the sheet material to be processed onto the conveyor 3, the conveyor 3 is immediately started. The conveyor 3 uses a conveyor belt drive to make the sheet material move smoothly forward along the preset track. Driven by the conveyor 3, the sheet material is gradually transported to the position of the fixed frame 12 until it reaches the middle area of ​​the fixed frame 12. When the sheet material accurately reaches the middle of the fixed frame 12, the electric telescopic rods 4 on the left and right sides of the fixed frame 12 will start simultaneously. The electric telescopic rods 4 are driven by a motor to rotate the screw, converting the rotational motion into linear motion, thereby realizing the extension of the telescopic rods. As the electric telescopic rods 4 extend, the connecting shell 5 at its end will gradually approach the sheet material for clamping and fixing. A semi-circular sponge pad 7 is installed on the fixing plate 6. When the fixing plate 6 approaches the sheet material, the sponge pad 7 will first contact the surface of the sheet material. The main function of the sponge pad 7 is to prevent the sheet material from being clamped during the clamping process. In this process, the friction between the plate and the board is reduced to avoid damage to the board surface due to excessive friction, thus ensuring the integrity of the board. The function of the sliding groove 21 is to restrict the rotation of the sliding block 9, ensuring that the sliding block 9 can only move linearly along the direction of the sliding groove 21. At this time, the rotating threaded rod 8 rotates and drives the sliding block 9 on the threaded rod 8 to slide. Simultaneously, the sliding causes the plug strip 10 to slide into the circular groove 11 for fixation. Through this fixing method, the fixing plate 6 is firmly fixed to the connecting shell 5. Conversely, when the fixing plate 6 needs to be replaced, the threaded rod 8 is rotated in the opposite direction, causing the sliding block 9 to drive the plug strip 10 out of the circular groove 11, so that the fixing plate 6 can be quickly disassembled. When the board is fixed, the pad printing equipment 13 receives the start signal and starts working. At this time, the ink pattern on the steel plate is transferred to the surface of the board through the pad printing head, so that the board completes the printing process and forms a finished product.

[0034] Reference Figure 2 , Figure 3 and Figure 6 The cleaning mechanism 2 includes a servo motor 205. The left side of the servo motor 205 is fixedly connected to the right side of the rear support shell 1. A rolling brush 206 is fixedly connected to the left side of the servo motor 205. When the servo motor 205 starts, it will drive the rolling brush 206 to rotate, thus cleaning the conveying equipment 3. A nozzle 204 is fixedly connected to the inner top wall of the rear support shell 1. A water pipe 201 is connected to the left side of the nozzle 204. A valve 202 is fixedly installed in the middle of the water pipe 201. When the valve 202 is opened... The water will then be transported to the nozzle 204 through the other end of the water pipe 201 with the help of an external water source for spraying, enabling the equipment to be deeply cleaned; a sealing ring 203 is fixedly connected to the right side of the valve 202, and the right side of the sealing ring 203 is fixedly connected to the top left side of the rear support shell 1. When water enters the water pipe 201, it will generate an impact force, which may cause water leakage. However, the sealing performance of the sealing ring 203 can seal the two ends of the connection, so that the water can be transported to the nozzle 204 for spraying without leakage.

[0035] Specifically, the servo motor 205 serves as the power source. When the equipment control system issues a cleaning command, the servo motor 205 starts. The servo motor 205 has precise speed control and stable power output characteristics. It can convert electrical energy into mechanical energy through the internal electromagnetic induction principle, driving the motor shaft to rotate. When rotating, it drives the rolling brush 206 to rotate for cleaning. When the valve 202 is opened manually, the water pipe 201 is transported by means of an external water source, and water is sprayed into the water pipe 201 for cleaning. When the water enters the water pipe 201, due to the pressure and impact of the water flow, water leakage may easily occur at the connection between the water pipe 201 and the rear support shell 1. At this time, the sealing ring 203 can seal the two ends of the connection, so that the water can be transported to the nozzle 204 without leakage for comprehensive wetting and cleaning, achieving a deep cleaning effect.

[0036] Reference Figure 1 and Figure 2 A fixing plate 20 is fixedly connected to the top left side of the pad printing equipment 13. A laser alignment device 19 is fixedly connected to the left side of the fixing plate 20. When the plate is fixed, the laser alignment device 19 on the pad printing equipment 13 can assist the electric telescopic rod 4 in precise fixing. Multiple iron plates 16 are fixedly connected to the bottom of the outer wall of the pad printing equipment 13. Tripods 15 are fixedly connected to the front and back sides of the multiple iron plates 16. The iron plates 16 are fixed on the pad printing equipment 13 and in contact with the ground. The tripods 15, based on the stability of triangles, are fixed to the iron plates 16 to enhance the fixing effect of the pad printing equipment 13.

[0037] Specifically, once the board reaches the fixed position, the laser beam projects onto the board surface to form a clear mark. At the same time, the electric telescopic rod 4 starts working, which can clamp the board more accurately, ensuring the positional accuracy of the board during the pad printing process. Through the contact between the iron plate 16 and the ground and the reinforcement of the tripod 15, the pad printing equipment 13 can maintain a stable state during operation, avoiding adverse effects on the pad printing quality caused by equipment shaking, ensuring the clarity and accuracy of the pad printing pattern, and improving product quality and production efficiency.

[0038] Reference Figure 2 A start switch 14 is fixedly connected to the front end of the outer wall of the pad printing equipment 13. The start switch 14 is electrically connected to the servo motor 205, the conveying device 3, the electric telescopic rod 4 and the pad printing equipment 13 respectively. When the start switch 14 is activated, the servo motor 205, the conveying device 3, the electric telescopic rod 4 and the pad printing equipment 13 on the equipment can start working.

[0039] Specifically, when the start switch 14 is activated, all electrically connected devices can begin to operate, enabling all electrically connected devices to enter the working phase.

[0040] Reference Figure 1 and Figure 3 A collection box 17 is fixedly installed on the inner wall of the rear support shell 1. A handle 18 is fixedly connected to the middle of the outer wall of the collection box 17. The collection box 17 can collect the dust that falls off during cleaning and the burrs that fall off when the rolling brush 206 is working. The handle 18 can help pull out the collection box 17 and pour out the dirty water in the collection box 17.

[0041] Specifically, the collection box 17 can clean up the dust that falls off when the cleaning mechanism 2 is operating and the burrs that fall off when the rolling brush 206 is working, and collect them to prevent them from falling to the ground and being difficult to clean. The handle 18 can help pull out the collection box 17 to pour out the dirty water in the collection box 17.

[0042] Working principle: Before using the device, the operator first places the board on the conveyor 3, and the conveyor belt drives the board to move along the track to the middle of the fixed frame 12. After the board reaches the fixed frame 12, the electric telescopic rods 4 on both sides extend and retract. When the electric telescopic rods 4 extend, the fixed plate 6 on the connecting shell 5 approaches the board. The sponge pad 7 on the fixed plate 6 contacts the board first to reduce friction and prevent damage. The sliding groove 21 restricts the rotation of the sliding block 9. The rotating threaded rod 8 causes the sliding block 9 to drive the plug strip 10 to slide into the circular groove 11 for fixing. Reverse rotation allows for disassembly and replacement. After the board is fixed, the pad printing device 13 is started. The pad printing head transfers the ink pattern of the steel plate to the board to complete the printing and become the finished product. This improves the alignment accuracy and quick disassembly of the device.

[0043] Furthermore, when the servo motor 205 starts, it drives the rolling brush 206 to rotate for cleaning. When the valve 202 is opened manually, the water pipe 201 is transported by means of an external water source, and water is sprayed into the water pipe 201 for cleaning again. Because the water flow has a certain pressure and impact force, water may seep into the connection when the water enters the nozzle 204. At this time, the sealing ring 203 can seal the two ends of the connection, so that the water can be transported into the nozzle 204 without leakage for comprehensive wetting and cleaning, thereby improving the deep cleaning effect of the device.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
