Description

Technical Field

[0001] This utility model relates to a laser marking disk, and more particularly to a laser array marking disk applied in the field of laser marking equipment technology. Background Technology

[0002] As a key component in a refrigeration system, the quality and performance of the expansion valve directly affect the operating efficiency and stability of the refrigeration system. During the production process of the expansion valve, it is necessary to mark it to facilitate product traceability, quality control, and after-sales service.

[0003] Chinese patent CN217394088U discloses an electronic component array disk for a laser marking machine. By matching the size of the electronic components with the three spatial parts of the cavity, the electronic components can be placed in different spaces. That is, one cavity can accommodate electronic components of any size among three different specifications.

[0004] Chinese patent CN221802129U discloses a self-controlled expansion valve that allows gaseous refrigerant to enter and be stored in the outer casing when refrigerant leaks at the weld seam, causing the casing to expand. This allows for visual detection of refrigerant leaks and effectively achieves the goal of quickly identifying the leak point when refrigerant leaks occur.

[0005] In the aforementioned comparative documents, when laser marking the expansion valves, the marking disc is fixed, requiring manual unloading of the marked expansion valves, resulting in low efficiency. Utility Model Content

[0006] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that when laser marking is performed, since the marking plate is fixed, the expansion valve needs to be manually unloaded after marking, resulting in low effect.

[0007] To address the aforementioned problems, this utility model provides a laser array marking disc, comprising a base, a processing chamber with a viewing door fixedly connected to the top of the base, a feeding port in the center of the processing chamber, and electric guide rails symmetrically fixedly connected to both sides of the feeding port inside the processing chamber. A slider is slidably connected to the electric guide rails, and a marking disc with multiple equidistant limiting grooves at its top is detachably connected to the slider. Connecting rods are symmetrically fixedly connected to both ends of the marking disc, and limiting blocks are fixedly connected to the bottom ends of the connecting rods. A groove is formed at the top of the slider, and a second electric push rod is embedded in the groove. The limiting block engages with the groove and the power end of the second electric push rod. A slot is formed at the end of the connecting rod away from the marking disc, and a first electric push rod is symmetrically arranged on the side of the processing chamber. The fixed end of the first electric actuator is embedded in the side wall of the processing chamber. The movable end of the first electric actuator is fixedly connected to a locking block, which engages with a slot. The fixed end of the first electric actuator is rotatably connected to a connecting sleeve fixed to the processing chamber on the side away from the connecting rod. The end of the connecting sleeve away from the first electric actuator is rotatably connected to a first rotating shaft, which passes through the connecting sleeve and is fixedly connected to the first electric actuator. The side end of the processing chamber is rotatably connected to a second rotating shaft located directly above the first rotating shaft. Both the side ends of the second rotating shaft and the first rotating shaft are fitted with belt pulleys, and the two belt pulleys are connected by a belt. The side end of the processing chamber is fixedly connected to a support plate, and a servo motor is fixedly connected to the support plate. The output end of the servo motor is connected to one of the second rotating shafts.

[0008] In the aforementioned laser array marking disc, the automatic rotation of the feeding port can achieve the effect of automatically feeding the qualified expansion valve.

[0009] As a further improvement of this application, the vertical projection of the marking disc is located inside the cross-section of the discharge port, and an inner chamber connected to the discharge port is opened on the side of the base.

[0010] As a further improvement of this application, a baffle is symmetrically connected to the inner wall of the discharge port via a connecting axis, and a third electric push rod is movably connected to the bottom end of the baffle via a hinge, and the fixed end of the third electric push rod is inclinedly and fixedly connected to the inner side wall of the chamber.

[0011] As a further improvement of this application, the inner compartment is provided with a storage drawer, and the cross-sectional area of ​​the storage drawer is larger than the cross-sectional area of ​​the discharge port. Support blocks are fixedly connected to the four corners of the inner wall of the storage drawer, and a filter layer is provided on the support blocks.

[0012] As another improvement of this application, the top of the fixed end of the second electric actuator is flush with the top of the groove, and the length of the movable end of the second electric actuator is greater than half the total length of the slider and the side wall of the connecting rod.

[0013] As a further improvement to this application, a controller for controlling the first electric actuator, the servo motor, the third electric actuator, the electric guide rail, and the second electric actuator is fixedly connected to the base.

[0014] As a further improvement to this application, a distance sensor is fixedly connected to the top of the processing chamber, located in front of the marking plate, and the distance sensor is electrically connected to the controller.

[0015] In summary, after positioning the expansion valve in the corresponding limiting groove on the marking plate, the marking plate is then placed on the slider. At this time, the second electric push rod is in a retracted state, the limiting block engages with the groove, and the bottom end of the limiting block engages with the second electric push rod, thus positioning the marking plate. Then, the controller activates the electric guide rail to drive the slider, moving the marking plate to the position corresponding to the laser marking head in the processing chamber for marking. After marking is completed, the controller can activate the second electric push rod to push the marking plate upwards until it reaches its maximum extension height. At this time, the distance sensor detects the marking plate and sends a signal to the controller to extend the first electric push rod, which engages the locking block with the corresponding slot. Then, the second electric push rod retracts, and the servo motor can be activated to drive the second rotating shaft, so that the two first rotating shafts rotate synchronously through the belt pulley and belt, thereby flipping the marking plate. The marked expansion valve can be poured from the discharge port into the inner chamber for collection. After disconnecting the first electric push rod from the marking plate, the drive slider resets the marking plate to the initial position and continues to feed and mark. Attached Figure Description

[0025] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] First implementation method:

[0027] Figures 1-5 A laser array marking disc is shown, comprising a base 1, a processing chamber 2 with a viewing door 5 fixedly connected to the top of the base 1, a feeding port 15 opening in the center of the processing chamber 2, electric guide rails 4 symmetrically fixedly connected to both sides of the feeding port 15 inside the processing chamber 2, sliders 16 slidably connected to the electric guide rails 4, and a marking disc 17 with multiple equidistant limiting grooves 18 on its top end detachably connected to the sliders 16, connecting rods 19 symmetrically fixedly connected to both ends of the marking disc 17, limiting blocks 23 fixedly connected to the bottom ends of the connecting rods 19, a groove 21 opening at the top of the slider 16, a second electric push rod 22 embedded in the groove 21, and the limiting block 23 engaging with the groove 21 and engaging with the power end of the second electric push rod 22, a slot opening at the end of the connecting rod 19 away from the marking disc 17, and first electric push rods 6 symmetrically arranged on the side of the processing chamber 2, and the first The fixed end of the electric actuator 6 is embedded in the side wall of the processing chamber 2. The movable end of the first electric actuator 6 is fixedly connected to a locking block 20, and the locking block 20 engages with the locking slot. The fixed end of the first electric actuator 6 is rotatably connected to a connecting sleeve 7 fixed to the processing chamber 2 on the side away from the connecting rod 19. The end of the connecting sleeve 7 away from the first electric actuator 6 is rotatably connected to a first rotating shaft 8, and the first rotating shaft 8 passes through the connecting sleeve 7 and is fixedly connected to the first electric actuator 6. The side end of the processing chamber 2 is rotatably connected to a second rotating shaft 10 located directly above the first rotating shaft 8. Both the side ends of the second rotating shaft 10 and the first rotating shaft 8 are fitted with belt pulleys 11, and the two belt pulleys 11 are connected to each other by a belt 12. The side end of the processing chamber 2 is fixedly connected to a support plate 9, and a servo motor 13 is fixedly connected to the support plate 9. The output end of the servo motor 13 is connected to one of the second rotating shafts 10.

[0028] The vertical projection of the marking plate 17 is located inside the cross section of the discharge port 15. The side end of the base 1 has an inner chamber that communicates with the discharge port 15. The top of the fixed end of the second electric push rod 22 is flush with the top of the groove 21, and the length of the movable end of the second electric push rod 22 is greater than half the total length of the side wall height of the slider 16 and the connecting rod 19. A controller that controls the first electric push rod 6, the servo motor 13, the third electric push rod 24, the electric guide rail 4, and the second electric push rod 22 is fixedly connected to the base 1. A distance sensor is fixedly connected to the top of the processing chamber 2 at the front of the marking plate 17, and the distance sensor is electrically connected to the controller.

[0029] Working principle: After the expansion valve is positioned in the corresponding limiting groove 18 on the marking plate 17, the marking plate 17 is placed on the slider 16. At this time, the second electric push rod 22 is in a retracted state, the limiting block 23 engages with the groove 21, and the bottom end of the limiting block 23 engages with the second electric push rod 22, thereby positioning the marking plate 17. Then, the controller activates the electric guide rail 4 to drive the slider 16 to move the marking plate 17 to the position corresponding to the laser marking head in the processing chamber 2 for marking. After marking is completed, the controller can activate the second electric push rod 22 to push the marking plate 17 upward. When pushed to the maximum extension of the second electric push rod 22... After reaching the height, the distance sensor detects the marking plate 17 and sends a signal to the controller to extend the first electric push rod 6, engaging the locking block 20 with the corresponding slot. Then, the second electric push rod 22 retracts, at which point the servo motor 13 can be activated to drive the second rotating shaft 10, causing the two first rotating shafts 8 to rotate synchronously through the belt pulley 11 and belt 12, thereby flipping the marking plate 17. The marked expansion valve can then be poured from the discharge port 15 into the inner chamber for collection. After disconnecting the first electric push rod 6 from the marking plate 17, the slider 16 is driven to reset the marking plate 17 to the initial position to continue feeding and marking.

[0030] By automatically flipping the discharge port 15, the expansion valve that has met the standards can be automatically discharged.

[0031] Second implementation method:

[0032] Figure 3 and Figure 7 The inner wall of the discharge port 15 is shown to be symmetrically connected to a baffle 3 via a connecting axis. The bottom end of the baffle 3 is movably connected to a third electric push rod 24 via a hinge 25. The fixed end of the third electric push rod 24 is inclinedly and fixedly connected to the side wall of the inner chamber. The inner chamber is provided with a storage drawer 14, and the cross-sectional area of ​​the storage drawer 14 is larger than that of the discharge port 15. Support blocks are fixedly connected at the four corners of the inner wall of the storage drawer 14, and a filter layer is provided on the support blocks.

[0033] Working principle: Before marking the expansion valve, first activate the third electric actuator 24 to push the baffle 3 upward, thereby closing the discharge port 15 to prevent dust generated during marking from entering the inner chamber. After marking is completed, insert the collection drawer 14 with the filter layer into the inner chamber. At this time, retract the third electric actuator 24, flip the two baffles 3 downward, open the discharge port 15, and pour the expansion valve into the collection drawer 14, where it falls onto the filter layer to filter the mixed powder. The filtered powder falls to the bottom of the collection drawer 14, making it easy to collect the clean expansion valve.

[0034] By setting baffle 3 and collection drawer 14 with filter layer, the expansion valve mixed with powder after reaching the standard can be filtered and separated, which facilitates collection. In addition, the collection drawer 14 can facilitate the collection and transportation of the whole batch of expansion valves.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
