Description

Technical Field

[0001] This utility model relates to the field of laser marking equipment technology, and in particular to a laser marking and positioning device for medical shells. Background Technology

[0002] In the production and management of medical devices, permanent marking is usually required on the outer shell of medical devices to achieve product traceability, anti-counterfeiting certification and compliance with relevant regulations. Laser marking technology has become the mainstream process for marking medical device outer shells due to its advantages such as high precision, non-contact, durable marking and the ability to engrave complex graphics and tiny text.

[0003] Patent CN213318353U discloses a laser marking positioning device. This device includes a base plate, a dual-axis cylinder, a worktable, and two adjustable positioning plates. The dual-axis cylinder is vertically mounted on the bottom of the base plate, with its piston rod connected upwards to drive the worktable to rise and fall. The worktable has sliding grooves on its front and rear sides. The two positioning plates are slidably positioned above the grooves via a slider structure and their positions can be adjusted laterally. Each positioning plate has a laser positioner, and a support frame is located at the rear end, with a marking head mounted on its top. This device adjusts the distance between the two positioning plates to accommodate workpieces of different sizes and uses the laser positioners on both sides to determine the starting and ending reference points for marking, thereby achieving precise positioning of the marking area. However, in practical applications, when positioning the workpiece, the two positioning plates need to be manually adjusted sequentially, and the laser positioners need to be triggered separately for coordinate calibration, increasing preparation time before marking and reducing production efficiency. Furthermore, the positioning plates only serve a dimensional limiting function and lack clamping capability; the workpiece may still shift due to external forces during the marking process.

[0004] Therefore, there is an urgent need to provide a laser marking and positioning device for medical shells that features automatic clamping and enables precise positioning and stable fixation of workpieces. Utility Model Content

[0005] In order to overcome the shortcomings of existing laser marking and positioning devices that still require manual operation and lack clamping function and have poor positioning stability during medical shell processing, this utility model provides a medical shell laser marking and positioning device with automatic clamping, which can achieve accurate positioning and stable fixation of the workpiece.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a medical shell laser marking and positioning device, comprising a conveyor table, a laser marking device disposed in the middle of the conveyor table, a fixed base disposed at the lower part of the conveyor table, a U-shaped sliding frame slidably disposed at the lower part of the fixed base, a cylinder mounted at the lower part of the conveyor table, the movable rod of the cylinder being fixedly connected to the U-shaped sliding frame, symmetrically distributed rotating shafts rotatably disposed at the upper part of the fixed base, a positioning plate being fixedly disposed on each rotating shaft, an mounting plate being disposed at the lower end of the rotating shaft, the mounting plate contacting and engaging with the inner side of the U-shaped sliding frame, a torsion spring being sleeved on the rotating shaft, one end of the torsion spring being fixedly connected to the positioning plate, and the other end being fixedly connected to the fixed base.

[0007] In one embodiment, mounting holes are provided at the corners of the conveyor table.

[0008] In one embodiment, a symmetrically distributed fixing frame is fixedly provided on the outer side of the positioning plate, and a gas storage tank is installed on the fixing frame. An air bladder is provided on the inner side of the positioning plate, and the air bladder is connected to the gas storage tank through a connecting pipe. An air pump is installed at the end of the connecting pipe near the gas storage tank.

[0009] In one embodiment, the airbag employs an embedded mounting design.

[0010] In one embodiment, a vision detector is installed at the lower center of the laser marking device.

[0011] In one embodiment, warning devices are provided on both sides of the lower part of the laser marking device, and the warning devices are electrically connected to the visual detector.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The device drives the U-shaped sliding frame to move through the cylinder, linking the mounting plate and the rotating shaft, and with the reset action of the torsion spring, realizes the automatic opening and closing of the positioning plate. The entire positioning and release process does not require manual intervention. It can work in conjunction with the conveyor and laser marking machine to form a fully automatic marking process, significantly reducing the intensity of manual operation and improving the automation level of the production line. In addition, under the drive of the cylinder, the positioning plate can stably clamp the two sides of the medical shell, effectively restricting the lateral degree of freedom and preventing it from shifting or vibrating during the marking process.

[0013] 2. By using a positioning plate in conjunction with a flexible airbag structure, the airbag can adaptively conform to the curved surface or irregular contour of the medical shell after inflation, achieving uniform and non-damaging flexible clamping, preventing problems such as blurred or misaligned markings caused by vibration or displacement during the marking process, and greatly improving marking accuracy and consistency.

Detailed Implementation

[0020] 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.

[0021] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5A laser marking and positioning device for medical casings includes a conveyor table 1. Mounting holes are provided at each of the four corners of the conveyor table 1, allowing for quick installation of the device on the ground via bolts. A laser marking device 2 is positioned in the center of the conveyor table 1. A fixed base 3 is located at the lower part of the conveyor table 1. A U-shaped sliding frame 4 is slidably mounted on the lower part of the fixed base 3. A cylinder 5 is mounted on the lower part of the conveyor table 1, with its movable rod fixedly connected to the U-shaped sliding frame 4. A rotating shaft 6 is symmetrically distributed on the upper part of the fixed base 3, with a positioning plate 7 fixedly mounted on each shaft 6. A mounting plate 8 is located at the lower end of each shaft 6, engaging with the inner side of the U-shaped sliding frame 4. The mounting plate 8 is pushed or released by the U-shaped sliding frame 4. This drives the rotating shaft 6 to rotate, controlling the positioning plate 7 to clamp or loosen. A torsion spring 9 is sleeved on the rotating shaft 6. One end of the torsion spring 9 is fixedly connected to the positioning plate 7, and the other end is fixedly connected to the fixed seat 3, so that the positioning plate 7 has a tendency to open outward. A vision detector 15 is installed in the middle of the lower part of the laser marking device 2 to collect images of the marking area in real time, detect the integrity, clarity and positional deviation of the marking content, and realize online monitoring of marking quality. Warning devices 16 are set on both the left and right sides of the lower part of the laser marking device 2. The warning devices 16 are electrically connected to the vision detector 15. When the detector detects a marking abnormality, it controls the warning device 16 to emit an audible and visual alarm signal to prompt the operator to deal with it in time and prevent defective products from flowing into the next process.

[0022] During operation, initially, cylinder 5 is in a retracted state. At this time, the inner side of the U-shaped sliding frame 4 contacts and abuts against the sides of the mounting plates 8. The rotating shaft 6 rotates against the spring force of the torsion spring 9, causing the two positioning plates 7 to rotate inward and be in a closed clamping state. When the medical shell needs to be inserted, cylinder 5 extends, pushing the U-shaped sliding frame 4 forward. Its inner side gradually disengages from the mounting plates 8. The mounting plates 8 are released outward under the restoring force of the torsion spring 9, driving the rotating shaft 6 to rotate outward, thereby causing the two positioning plates 7 to open outward, forming sufficient space for the workpiece to enter. Subsequently, the workpiece to be marked is placed... The medical casing is placed on the conveyor table 1 and then conveyed by the conveyor table 1 to the area directly below the laser marking machine 2. Then, the cylinder 5 retracts, driving the U-shaped sliding frame 4 to move backward. Its inner side contacts and presses the mounting plate 8 again, forcing the rotating shaft 6 to drive the positioning plate 7 to rotate inward until it clamps both sides of the medical casing, completing the automatic positioning. After positioning, the laser marking machine 2 is started to perform the marking operation. After the marking is completed, the cylinder 5 extends again, the U-shaped sliding frame 4 moves forward, releasing the mounting plate 8. The positioning plate 7 automatically opens under the action of the torsion spring 9, making it easy to take out the finished product and put in the next workpiece.

[0023] Example 2: Based on Example 1, please refer to... Figure 4The positioning plate 7 is fixedly provided with symmetrically distributed fixing frames 10 on the outside. The two fixing frames 10 are used to install the air tank 13. An air bladder 11 is provided on the inside of the positioning plate 7. The air bladder 11 adopts an embedded installation design, which is convenient for disassembly for maintenance and cleaning. The air bladder 11 is connected to the air tank 13 through a connecting pipe 12. An air pump 14 is installed at one end of the connecting pipe 12 near the air tank 13. The air pump 14 delivers the compressed gas in the air tank 13 to the air bladder 11 to realize the expansion and contraction of the air bladder 11.

[0024] When the positioning plate 7 positions and clamps the medical shell, the air pump 14 is activated to inject the pre-stored compressed gas in the air tank 13 into the air bladder 11 inside the positioning plate 7 through the connecting pipe 12, causing the air bladder 11 to gradually expand. During this process, it can adaptively conform to the curved surface or irregular contour of the edge of the medical shell, forming a uniform contact pressure and achieving flexible clamping. This clamping method avoids scratches or stress concentration on the shell surface that may be caused by rigid clamps, and effectively prevents the workpiece from undergoing slight displacement during the marking process, ensuring the accuracy and consistency of the laser marking position. After marking is completed, the air pump 14 can be turned on to expel the gas in the air bladder 11, causing it to contract and reset, thereby releasing the workpiece, making it easier to remove the finished product and enter the next cycle.
