Description

Technical Field

[0001] This utility model relates to the field of water pump stator processing technology, specifically a laser marking device with a positioning mechanism. Background Technology

[0002] During the manufacturing process, water pump stators undergo marking on their outer surface to identify their model, production batch, manufacturer information, or other relevant markings. This marking is typically done using laser marking. Laser marking utilizes a high-energy laser beam to locally ablate or evaporate the material on the outer surface of the stator, thus engraving clear characters, numbers, or patterns. Because the marking location on the water pump stator is on its outer planar structure, and currently, marking is often performed simultaneously during transport by a conveyor, it lacks a corresponding positioning structure and cannot accurately locate the stator's axis. This results in varying distances between the water pump stator and the marking machine. If the laser marking machine is too far from the stator surface, the laser beam will diffuse before reaching the surface, causing the focal point to become larger, resulting in a blurry and unclear marking effect. If it is too close, the focal point may be too small, making it difficult to cover the required marking area. Utility Model Content

[0003] The purpose of this invention is to provide a laser marking device with a positioning mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a laser marking device with a positioning mechanism, comprising:

[0005] The equipment frame has multiple drive rollers symmetrically and rotatably mounted on its inner wall, and a synchronous belt drive assembly that drives the drive rollers to rotate is mounted on the outer side of the equipment frame.

[0006] The positioning part is located in the middle of the equipment frame. The positioning part includes a lifting limit plate and a support plate. An inner support ring is fixedly connected to the top of the support plate. Multiple extrusion plates are equidistantly arranged in the middle of the inner support ring with respect to the center of the inner support ring. A conical block that drives the extrusion plates to move outward is arranged inside the inner support ring.

[0007] The laser marking equipment is placed on the outside of the equipment frame.

[0008] Preferably, the drive rollers located at one end of the equipment frame are connected by a transmission rod. The synchronous belt drive assembly is fixed to the outer shell of the equipment frame. A servo motor is fixed to one end of the bottom of the shell. The servo motor is connected to one of the drive rollers through a reducer. A synchronous pulley is fixed to one end of each drive roller through a rotating shaft. Adjacent synchronous pulleys are connected by a synchronous belt drive.

[0009] Preferably, a dual-axis cylinder is fixedly connected to the bottom of the equipment frame, and the output end of the dual-axis cylinder is fixedly connected to the limiting plate.

[0010] Preferably, a support frame is fixedly connected to the bottom of the equipment frame, and a cylinder is fixedly connected to the bottom of the support frame. A limit slide rod is fixedly connected to the output end of the cylinder.

[0011] Preferably, the limiting slide rod is slidably connected to the equipment frame, the top of the limiting slide rod is fixedly connected to the support plate, the bottom of the support plate is fixedly connected to a second cylinder, and the output end of the second cylinder is fixedly connected to a conical block.

[0012] Preferably, the end of the extrusion plate adjacent to the conical block is a slope, and a limit rod is fixedly connected to the top end of the extrusion plate. The limit rod is slidably connected to the inner support ring, and a spring is sleeved on the outside of the limit rod to drive the extrusion plate to reset inside the inner support ring.

[0013] Preferably, a dual-axis cylinder is fixedly connected to the outer side of the equipment frame and at the position corresponding to the laser marking equipment.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the water pump stator is delivered to the designated position, the limiting plate is raised, and the driving roller stops working, initially positioning the water pump stator in a specific position. Cylinder 1 drives the limiting slide rod and support plate to rise, and the support plate lifts the water pump stator to separate it from the driving roller. At the same time, the inner support ring is inserted into the middle of the water pump stator, realizing the vertical positioning of the water pump stator. Cylinder 2 drives the conical block to move upward, and uses the inclined surface of the conical block to squeeze the extrusion plate, causing the extrusion plate to move outward at the same time, squeezing and fixing it from the inside of the water pump stator. This internal fixing method can ensure that the water pump stator is fixed in the horizontal direction, and multiple extrusion plates act simultaneously, with uniform fixing force and high positioning accuracy. Dual-axis cylinder 2 drives the extrusion positioning plate to contact the outside of the water pump stator. Utilizing the elasticity of spring 2, when the water pump stator is fixed by the internal extrusion plate, it provides lateral auxiliary positioning and top limiting of the water pump stator, preventing the water pump stator from tilting during the fixing process, further improving the positioning accuracy and stability.

[0022] It should be noted that in this embodiment, a controller and a corresponding operation panel are provided. The water pump stator is placed on top of the drive roller 3, and the drive roller 3 drives the water pump stator forward. There is an infrared sensor on one side of the equipment frame 1. When the water pump stator is transported to the position of the infrared sensor, the infrared sensor detects the signal and transmits it to the controller. The controller controls the equipment drive limit plate 19 to rise and controls the drive roller 3 to stop working. At this time, the inner ring of the water pump stator is placed above the inner support ring 12. The support plate 11 drives the inner support ring 12 to move upward. The support plate 11 lifts the water pump stator and controls the conical block 14 to move upward. Under the action of the inclined surface of the conical block 14, the extrusion plate 15 moves outward at the same time, thereby extruding and fixing the water pump stator from the inside. Then, the outer side is laser-marked by the laser marking device 6.

[0023] In one embodiment, the drive rollers 3 located at one end of the equipment frame 1 are connected by a transmission rod 5. The synchronous belt drive assembly 2 is fixed to the outer shell of the equipment frame 1. A servo motor is fixed to one end of the bottom of the shell. The servo motor is connected to one of the drive rollers 3 through a reducer. A synchronous pulley is fixed to one end of each drive roller 3 through a rotating shaft. Adjacent synchronous pulleys are connected by a synchronous belt drive.

[0024] It should be noted that, in this embodiment, when the drive roller 3 needs to rotate, the servo motor drives one of the drive rollers 3 on one side of the equipment frame 1 to rotate, and the drive roller 3 drives the drive roller 3 on the other side to rotate through the transmission rod 5. The two adjacent drive rollers 3 are connected by a synchronous pulley and a synchronous belt to achieve the conveying of the water pump stator.

[0025] In one embodiment, a dual-axis cylinder 9 is fixedly connected to the bottom of the equipment frame 1, and the output end of the dual-axis cylinder 9 is fixedly connected to the limiting plate 19.

[0026] It should be noted that in this embodiment, when the water pump stator is in contact with the infrared sensor structure, the controller controls the dual-axis cylinder 9 to drive the limit plate 19 to rise, thereby blocking the water pump stator in the corresponding position.

[0027] In one embodiment, a support frame 7 is fixedly connected to the bottom of the equipment frame 1, and a cylinder 8 is fixedly connected to the bottom of the support frame 7. A limiting slide rod 10 is fixedly connected to the output end of the cylinder 8. The limiting slide rod 10 is slidably connected to the equipment frame 1. The top of the limiting slide rod 10 is fixedly connected to the support plate 11. A cylinder 13 is fixedly connected to the bottom of the support plate 11. The output end of the cylinder 13 is fixedly connected to the conical block 14. The end of the extrusion plate 15 adjacent to the conical block 14 is a slope. A limiting rod 16 is fixedly connected to the top end of the extrusion plate 15. The limiting rod 16 is slidably connected to the inner support ring 12. A spring 17 is sleeved on the outside of the limiting rod 16 to drive the extrusion plate 15 to reset inside the inner support ring 12.

[0028] It should be noted that in this embodiment, when the limiting plate 19 blocks the workpiece at the predetermined position, the controller controls the cylinder 8 to lift the limiting slide rod 10. The limiting slide rod 10 rises in the middle of the equipment frame 1 and drives the support plate 11 to move upward. During the movement, the support plate 11 lifts the water pump stator, separating it from the drive roller 3, and the inner support ring 12 is inserted into the middle of the water pump stator. Under the action of the timer, the cylinder 13 drives the conical block 14 to move upward. The inclined surface of the conical block 14 presses the extrusion plate 15 outward. During the movement of the extrusion plate 15, the limiting rod 16 moves into the inner support ring 12 and compresses the spring 17, so that the extrusion plate 15 presses and fixes the inner ring of the water pump stator. When the cylinder 13 drives the conical block 14 to reset, the spring 17 drives the extrusion plate 15 to reset into the inner support ring 12.

[0029] In one embodiment, a dual-axis cylinder 18 is fixedly connected to the outer side of the equipment frame 1 and to the position corresponding to the laser marking device 6. A metal frame is fixedly connected to the output end of the dual-axis cylinder 18. A T-shaped extrusion positioning plate 4 is slidably connected to one side of the metal frame. A spring 20 is installed between the extrusion positioning plate 4 and the metal frame. A metal rod that is slidably connected to the metal frame is fixedly connected to one side of the extrusion positioning plate 4. The spring 20 is sleeved on the outer side of the metal rod.

[0030] It should be noted that in this embodiment, the two side planes of the water pump stator are located above the drive roller 3. When the cylinder 1 8 drives the support plate 11 to lift the water pump stator through the limiting slide rod 10, the controller controls the dual-axis cylinder 2 18 to extend. The dual-axis cylinder 2 18 drives the squeezing positioning plate 4 to contact the outside of the water pump stator. With the two ends of the water pump stator as the planar structure, one of the planes is used for marking. When the dual-axis cylinder 2 18 drives the squeezing positioning plate 4 to fit against the plane of one end of the water pump stator, one side of the squeezing positioning plate 4 fits against the top of the water pump. When the squeezing plate 15 moves outward to fix the water pump stator, the water pump stator squeezes the squeezing positioning plate 4 and the corresponding spring 20 to one side, so that the water pump stator and the support plate 11 are concentric. In this way, under the limiting action of the squeezing positioning plate 4 on the top of the water pump stator, the squeezing plate 15 is prevented from tilting when fixing the inner ring of the water pump stator.
