Medical slide marking machine

Abstract

The application relates to a medical slide marking machine, which comprises a mounting frame, a slide loading box, a slide pushing device, a slide positioning and discharging device, a laser marking device and a slide collecting device. The slide loading box is only allowed to have one slide in and out of the slide outlet, so that the situation of missing printing due to adsorption and adhesion of the slide is avoided. The slide positioning and discharging device comprises a first positioning block, a second positioning block, a first motor, a first inclined slide and a first slide inductor. The first positioning block and the second positioning block can position the periphery of the slide, so that the position of the slide during marking has consistency and accuracy. When the second positioning block rotates downward, one end of the slide is inclined downward, and gradually falls on the first inclined slide, so that the slide and the first inclined slide are prevented from colliding violently and the slide is prevented from being damaged. The application can realize automatic operations such as slide feeding, positioning and discharging, and the slide is not easy to be damaged, the movement is stable, and the marking accuracy is high.

Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a medical slide marking machine. Background Technology

[0002] A glass slide is a container for storing pathological specimens. To identify slides, they need to be marked with characters such as QR codes, pathology numbers, and patient identification information. A slide numbering machine is a machine that prints serial numbers on slides in batches. By numbering each slide, it facilitates differentiation and prevents slides from being mixed up.

[0003] Chinese patent application CN217197477U, entitled "A Laser Marking Machine for Laterally Pushing Glass Slides," discloses a glass slide marking machine that uses laser printing. Laser printing has many advantages: it eliminates the need for consumables such as ink cartridges and ribbons, can print various texts, characters, numbers, QR codes, and other information, produces clear prints, and has a fast printing speed. The disclosed glass slide marking machine also boasts a simple structure, stable operation, and compact size. It can also achieve automatic feeding, automatic marking, automatic discharging, and automatic collection. However, the positioning and unloading structures of the glass slides are too simple, resulting in insufficient positioning accuracy and a lack of buffering during unloading, which easily leads to glass slide fragmentation. Further improvements are necessary. Summary of the Invention

[0004] In order to solve the technical problem that existing slide marking machines cannot effectively automate operations such as slide positioning and feeding, this invention provides a medical slide marking machine.

[0005] The technical solution provided in this application is as follows: A medical slide marking machine includes a mounting frame, a slide loading box, a slide pushing device, a slide positioning and feeding device, a laser marking device, and a slide collecting device; the slide loading box is placed on the mounting frame and is used to accommodate multiple stacked slides. The slide loading box has a slide pushing port and a slide exit port on its bottom sides, respectively. The slide exit port allows only one slide to enter and exit at a time; the slide pushing device includes a first driving mechanism, a horizontal driving block, and a slide pushing head. The slide pushing head is disposed on the horizontal driving block, which is horizontally slidably disposed on the mounting frame via a first guide rail slider assembly. The first driving mechanism is disposed on the mounting frame and is used to drive the horizontal driving block and the slide pushing head to move horizontally. The slide pushing head enters from the slide pushing port and pushes the slide at the bottom of the slide loading box out from the slide exit port; the slide positioning and feeding device includes a first positioning block, a second positioning block, a first motor, a first inclined slide rail, and a second positioning block. A slide sensor is included. The first positioning block, the first motor, and the first inclined slide are all mounted on a mounting frame. The second positioning block is mounted on the motor shaft of the first motor. The first motor drives the second positioning block to rotate in a vertical plane. When the second positioning block rotates to a horizontal position, it receives the slide pushed out from the slide pusher together with the first positioning block and positions the slide around its perimeter. The first slide sensor is used to detect the presence or absence of a slide on the first and second positioning blocks. When the second positioning block rotates downward, one end of the slide tilts downward and gradually falls onto the first inclined slide. The first inclined slide is located below the first and second positioning blocks and is used to receive the slide and allow it to slide into a slide collecting device under its own weight. A laser marking device is used to laser mark the positioned slide. The slide collecting device is used to receive the slide that slides down from the first inclined slide and collect it.

[0006] By adopting the above technical solution, the medical slide marking machine described in this application still uses conventional laser printing for marking. It utilizes a slide loading box and a slide pushing device to load slides. Slides are stacked and placed in the slide loading box, which has a large capacity. By limiting the height of the slide outlet, it ensures that only one slide can be pushed out at a time, preventing missed printing due to slide adhesion. The slide pushing head is mounted on the mounting frame via a first guide rail slider assembly, ensuring smooth and precise movement. After being pushed out, the slide enters between the first and second positioning blocks (when in a horizontal state) and is positioned by their periphery, ensuring consistent and accurate positioning during marking. After marking, the first motor drives the second positioning block to rotate downwards, causing one end of the slide to descend while the other remains stationary, gradually tilting until it finally lands on the first inclined slide. The speed of the first motor is adjusted appropriately to avoid violent impact between the slide and the first inclined slide, preventing damage. Under the influence of gravity, the slide slides downwards along the first inclined slide and enters the slide collection device. This application can effectively automate the feeding, positioning, and unloading of glass slides, without easily damaging the slides, ensuring smooth movement and high marking accuracy.

[0007] In summary, this application includes at least one of the following beneficial technical effects:

[0008] 1. This application utilizes a slide loading box and a slide pushing device to load slides. The slides are stacked and placed in the slide loading box, which has a large capacity. By limiting the height of the slide outlet, it is ensured that only one slide can be pushed out at a time, thus preventing the situation of slides being missed due to adsorption and adhesion during printing.

[0009] 2. The first and second positioning blocks can perform peripheral positioning of the slide, ensuring the consistency and accuracy of the slide's position during marking;

[0010] 3. Adjust the speed of the first motor to avoid violent impact between the glass slide and the first inclined slide, thus preventing damage to the glass slide;

[0011] 4. This application can effectively automate the feeding, positioning and unloading of glass slides, without easily damaging the slides, with smooth movement and high marking accuracy. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1-29 This application will be described in further detail.

[0043] Example 1:

[0044] Reference Figures 1 to 3This application discloses a medical slide marking machine, including a mounting frame 1, a slide loading box 2, a slide pushing device 3, a slide positioning and feeding device 4, a laser marking device 5, and a slide collecting device 6. The slide loading box 2 is placed on the mounting frame 1 and is used to accommodate multiple stacked slides 100. The slide loading box 2 has a slide pushing port 21 and a slide exit port 22 on both sides of its bottom. The slide exit port 22 can only allow one slide 100 to enter or exit at a time. The slide pushing device 3 includes a first driving mechanism 31. The device comprises a horizontal drive block 32 and a slide pusher 33. The slide pusher 33 is mounted on the horizontal drive block 32. The horizontal drive block 32 is horizontally slidably mounted on the mounting frame 1 via a first guide rail slider assembly 34. The first drive mechanism 31 is mounted on the mounting frame 1 and is used to drive the horizontal drive block 32 and the slide pusher 33 to move horizontally. The slide pusher 33 enters from the slide pusher port 21 and pushes the slide 100 at the bottom of the slide loading box 2 out from the slide outlet 22. The slide positioning and unloading device 4 includes a first guide rail slider assembly 34 and a first drive mechanism 35. The system comprises a positioning block 41, a second positioning block 42, a first motor 43, a first inclined slide 44, and a first slide sensor 45. The first positioning block 41, the first motor 43, and the first inclined slide 44 are all mounted on the mounting bracket 1. The second positioning block 42 is mounted on the motor shaft of the first motor 43. The first motor 43 drives the second positioning block 42 to rotate in the vertical plane. When the second positioning block 42 rotates to a horizontal state, it receives the slide 100 pushed out from the slide pusher 3 together with the first positioning block 41 and performs peripheral positioning of the slide 100. The first slide sensor 45 is used to detect the presence or absence of the slide 100 on the first positioning block 41 and the second positioning block 42. When the second positioning block 42 rotates downward, one end of the slide 100 tilts downward and gradually falls onto the first inclined slide 44. The first inclined slide 44 is located below the first positioning block 41 and the second positioning block 42 and is used to receive the slide 100 and allow the slide 100 to slide into the slide collecting device 6 under its own gravity. The laser marking device 5 is used to mark the positioned glass slide 100 with a laser; the glass slide collecting device 6 is used to receive the glass slide 100 that slides down from the first inclined slide rail 44 and collect the glass slide 100.

[0045] The medical slide marking machine described in this application still uses conventional laser printing for marking. It utilizes a slide loading box 2 and a slide pushing device 3 to feed slides 100. Slides 100 are stacked in the slide loading box 2, which has a large capacity. By limiting the height of the slide outlet 22, it ensures that only one slide 100 can be pushed out at a time, preventing missed printing due to slide adhesion. The slide pushing head 33 is mounted on the mounting frame 1 via the first guide rail slider assembly 34, ensuring smooth and precise movement. After being pushed out, the slide 100 enters between the first positioning block 41 and the second positioning block 42 (when in a horizontal state). The slide 100 is positioned by the first positioning block 41 and the second positioning block 42, ensuring consistency and accuracy in its position during marking. After marking, the first motor 43 drives the second positioning block 42 to rotate downwards, causing one end of the slide 100 to descend while the other end remains stationary, gradually tilting until it finally lands on the first inclined slide 44. The speed of the first motor 43 is adjusted appropriately to prevent violent impact between the slide 100 and the first inclined slide 44, thus preventing damage to the slide 100. Under the influence of gravity, the slide 100 slides downwards along the first inclined slide 44 and enters the slide collection device 6. This application effectively automates slide loading, positioning, and unloading operations, minimizing damage to the slide 100, ensuring smooth movement, and achieving high marking accuracy.

[0046] Reference Figures 7 to 9 The slide loading box 2 includes a box body 24 and a base plate 25. The box body 24 has a receiving cavity for accommodating multiple stacked slides 100. The base plate 25 is fixed to the bottom of the box body 24 to support the slides 100 inside the box body 24. A slide pusher 21 is located at the bottom of the front wall of the box body 24, and a slide outlet 22 is located at the bottom of the rear wall of the box body 24. In this embodiment, the slide outlet 22 has a length of 77.6 mm and a width of 1.5 mm, which meets the placement requirements of most commercially available slides. Multiple protruding first vertical guide strips 26 are provided on the inner walls of both side walls of the box body 24, and multiple protruding first vertical guide strips 26 are also provided on the inner wall of the rear wall of the box body 24. The top of each first vertical guide strip 26 is an upwardly converging guide slope 261, which has a guiding function, allowing the glass slide 100 to smoothly enter the receiving cavity. The multiple first vertical guide strips 26 are generally distributed or evenly arranged, which allows the edge of the glass slide 100 to completely detach from the inner wall of the box body 24. This embodiment has six first vertical guide strips 26, which makes the feeding of the glass slide 100 smoother.

[0047] When the slide 100 is loaded into the slide loading box 2, the top of the first vertical guide bar 26 is an upwardly converging guide slope 261, which can guide the slide 100 into the receiving cavity of the box body 24. Only the first vertical guide bar 26 will contact the edge of the slide 100. The contact area is very small, and the friction generated is also very small. The slide 100 is not easy to tilt or get stuck, and the loading is smoother. When the slide 100 is pushed out, the edge of the slide 100 only contacts the first vertical guide bar 26 on the two side walls of the box body 24. The contact area is small, and the friction generated is also small. It is not easy to be pushed tilted, which greatly reduces the probability of fragmentation. The gap reserved between the slide 100 and the first vertical guide bar 26 can be designed to be smaller, thereby improving the positional accuracy of the slide 100 after it is pushed out.

[0048] Reference Figure 10 The mounting frame 1 is provided with a positioning groove 11. The lower end of the slide loading box 2 is inserted into the positioning groove 11. The outer walls of both sides of the slide loading box 2 are also provided with positioning posts 23. The upper end of the mounting frame 1 is provided with a corresponding slot 12. The positioning posts 23 are inserted into the slots 12 from above. The bottom of the positioning groove 11 on the mounting frame 1 is provided with a contact switch 13 for detecting whether the slide loading box 2 is placed on the mounting frame 1. The positioning groove 11 only plays a preliminary positioning role for the slide loading box 2. After the positioning posts 23 on both sides of the box body 24 are inserted into the slots 12, a fine positioning is formed, which can make the placement angle of the slide loading box 2 more upright and reduce the amount of sway. In this way, when the slide 100 is pushed out, the friction between it and the first vertical guide strip 26 can be reduced. The slide loading box 2 is triggered by its own weight. When the slide loading box 2 is removed, the contact switch 13 returns to its initial state, thereby sensing whether the slide loading box 2 exists. When the slide loading box 2 is sensed, the medical slide numbering machine will start the numbering operation.

[0049] Reference Figure 11 The top surface of the pusher head 33 is a driving inclined surface 331. The front end of the driving inclined surface 331 is higher than the rear end. The pusher head 33 is floatingly mounted on the horizontal driving block 32. When there is no external force, the pusher head 33 is at the upper stop point and can move horizontally forward to push the bottom glass slide in the glass slide loading box 2. When the pusher head 33 retracts, the glass slide 100 in the glass slide loading box 2 relies on gravity to press the pusher head 33 down through the driving inclined surface 331 to reduce the friction between the pusher head 33 and the glass slide 100.

[0050] Reference Figure 11The pusher head 33 is hinged to the horizontal drive block 32 via a rotating shaft 35. A first tension spring 36 is also provided between the tail end of the pusher head 33 and the horizontal drive block 32. The first tension spring 36 is used to keep the pusher head 33 at the top dead center of rotation when there is no external force. The pusher head 33 rotates as a whole, and the front end of the pusher head 33 will float up and down during the rotation. The upward buoyancy of the pusher head 33 can be adjusted by adjusting the tension of the first tension spring 36.

[0051] In this application, the slide pusher 33 is designed to float up and down. When no external force is applied, the slide pusher 33 can stably be at the top stop. When the slide pusher 33 moves forward horizontally, it can push out the bottom slide 100 in the slide loading box 2 horizontally. When the slide pusher 33 retracts, the slides 100 in the slide loading box 2 rely on gravity to press the slide pusher 33 down through the driving inclined surface 331. The slide pusher 33 can then smoothly exit from the slide loading box 2 without having to lift all the slides 100 above. At this time, the friction between the slide pusher 33 and the slide 100 is related to the upward buoyancy of the slide pusher 33 and is not related to the weight of all the slides 100 above. The smaller the upward buoyancy of the slide pusher 33 (under the condition that the slide pusher 33 can float normally), the smaller the friction between the two, the less wear on the slide 100, and the less likely it is to scratch the surface of the slide 100.

[0052] Reference Figure 10 The first drive mechanism 31 adopts a transmission method of motor, synchronous pulley and synchronous belt. The mounting bracket 1 is also equipped with a first position sensor 311. The technology is mature, the cost is low, the movement speed is appropriate, and the noise is low. With the first position sensor 311, the movement limit positions of the horizontal drive block 32 and the pusher head 33 can be well controlled, and the glass slide 100 can be pushed into place.

[0053] Reference Figure 12 and Figure 13 The slide positioning and unloading device 4 also includes a second position sensor 46 for detecting the angular position of the second positioning block 42. By setting the second position sensor 46, it can be ensured that the second positioning block 42 can be rotated upward to a horizontal state to smoothly receive the slide 100 that has been moved over. It can also be ensured that the second positioning block 42 can be rotated downward to the required angle, thereby ensuring that one end of the slide 100 can be completely detached from the second positioning block 42 and fall smoothly onto the first inclined slide 44.

[0054] Reference Figures 14 to 18The slide collecting device 6 includes a second inclined slide 61, a slide collecting groove 62, a lifting handle 63, a second motor 64, a lead screw and slider transmission assembly 65, a first one-way check block 66, and a second one-way check block 67. The second inclined slide 61 is used to connect with the first inclined slide 64. The slide collecting groove 62 is inclinedly arranged above the second inclined slide 61. The second motor 64 and the lead screw and slider transmission assembly 65 are arranged on the side of the second inclined slide 61. The lifting handle 63 is arranged on the lead screw and slider transmission assembly 65 and is located at the bottom of the second inclined slide 61, and slides with the second inclined slide 61. The surfaces are parallel. The first one-way check block 66 and the second one-way check block 67 are respectively hinged to both ends of the slide collection groove 62. The second motor 64 drives the lifting handle 63 to move up and down in the slide collection groove 62 through the lead screw slider transmission assembly 65, so as to push the slide 100 above the first one-way check block 66 and the second one-way check block 67. The first one-way check block 66 and the second one-way check block 67 are pushed to rotate upward, so that the slide 100 passes through the first one-way check block 66 and the second one-way check block 67, and rotates downward under the action of the gravity of the slide 100 to prevent the slide from falling back onto the second inclined slide 61.

[0055] To ensure the smooth descent of the glass slide, the preferred inclination angles of the first inclined slide 44 and the second inclined slide 61 are 25-45 degrees. Furthermore, the sliding surface of the first inclined slide 44 is wholly or partially wavy 441, resulting in a smaller contact area between the glass slide 100 and the sliding surface, thus reducing sliding friction and facilitating descent. This solution ensures the smooth descent of the glass slide 100 while preventing excessively fast descent to avoid impact damage. The sliding surface of the second inclined slide 61 is slightly lower than that of the first inclined slide 44, and the upper surface of the lifting handle 63 is slightly lower than that of the second inclined slide 61. This further ensures the smooth descent of the glass slide 100 under gravity without obstruction.

[0056] The length of the glass slide 100 must be greater than the distance between the first one-way check block 66 and the second one-way check block 67 when they are in the blocking state, and less than the distance between the first one-way check block 66 and the second one-way check block 67 when they are in the passing state. This allows the glass slide 100 to pass through the first one-way check block 66 and the second one-way check block 67 without being able to retract. The length of the lifting handle 63 should be less than the distance between the first one-way check block 66 and the second one-way check block 67 when they are in the blocking state. This ensures that the lifting handle 63 can always move freely up and down without interfering with the first one-way check block 66 and the second one-way check block 67.

[0057] Since the glass slide 100 is tilted in the glass slide collecting groove 62, a certain amount of one-sided friction will be generated between the glass slide 100 and the glass slide collecting groove 62. The one-sided friction not only increases the wear on the side of the glass slide 100, but may also cause the glass slide 100 to flip over during the process of the glass slide 100 rising (there is no friction on the upper side of the glass slide 100, so it may tilt upwards and flip over). Once it flips over, it may hit the glass slide collecting groove 62 or the second one-way check block 67, and the glass slide 100 will easily break.

[0058] Reference Figure 16 To address the aforementioned technical problem, the slide collecting groove 62 has multiple protruding second guide strips 621 (vertically arranged) on its lower inner side wall. These second guide strips 621 are in line contact with the slide 100 to reduce friction between the slide 100 and the inner wall of the slide collecting groove 62. In this embodiment, there are specifically two second guide strips 621, which maintain the balanced support for the slide 100.

[0059] Reference Figure 14 and Figure 15 The slide collecting groove 62 is further provided with grooves 622 on the two side walls at the upper and lower ends for accommodating the first one-way check block 66 and the second one-way check block 67. When the first one-way check block 66 and the second one-way check block 67 are pushed upward and rotated, they can be completely retracted into the grooves 622 without affecting the upward movement of the slide 100.

[0060] Reference Figure 14 The second inclined slide 61 is further equipped with a second slide sensor 69 at its lower end, used to detect the presence or absence of slides 100 on the lifting handle 63. When a slide 100 slides down from the second inclined slide 61 and enters the lifting handle 63, the second slide sensor 69 detects the slide 100, and the control system of the medical slide marking machine controls the second motor 64 to start collecting slides 100. The slide collection trough 62 is equipped with a full-load sensor 691 at its upper part, used to detect whether the slide collection trough 62 is full of slides 100. When there are enough slides 100 in the slide collection trough 62, the topmost slide 100 will trigger the full-load sensor 691. After receiving the corresponding signal, the control system of the medical slide marking machine will issue a full-load notification and stop receiving slides 100, stopping the marking process until the staff removes the slides 100, at which point the marking and collection of slides 100 will resume.

[0061] Reference Figure 14 This application uses a combination structure of a second motor 64 and a lead screw and slider transmission assembly 65 to drive the lifting handle 63 to lift, which has the advantages of high repeatability, small error and long service life.

[0062] Reference Figure 19 and Figure 20 The slide positioning and feeding device 4 and the slide collecting device 6 adopt a modular docking assembly method. The docking surface of the slide positioning and feeding device 4 is provided with a plug-in positioning hole 14 and a first electrical connector 15. The docking surface of the slide collecting device 6 is provided with a plug-in positioning protrusion 692 and a second electrical connector 693 at corresponding positions. The plug-in positioning protrusion 692 is inserted into the plug-in positioning hole 14 to realize the docking assembly of the slide positioning and feeding device 4 and the slide collecting device 6. The plug-in positioning protrusion 692 and the plug-in positioning hole 14 are matched in shape, but neither is circular to prevent relative rotation between the two and avoid angular deviation after assembly. In this way, the first electrical connector 15 and the second electrical connector 693 can be smoothly docked, so that the slide positioning and feeding device 4 and the slide collecting device 6 can be electrically connected. In addition, the inner wall of the insertion positioning hole 14 is provided with an elastic ball 16, and the side of the insertion positioning protrusion 692 is provided with an arc-shaped anti-retraction groove 694. When the insertion positioning protrusion 692 is inserted into the insertion positioning hole 14, the elastic ball 16 on the side is first compressed and then locked into the anti-retraction groove 694, which can effectively prevent the insertion positioning protrusion 692 from coming out. When it is necessary to disassemble the slide collecting device 6, a large pulling force is applied to compress the elastic ball 16 back, which can release the lock. The slide collecting device 6 is a functional module that can be quickly disassembled and assembled, reducing the assembly difficulty and making it easy to use. In addition, in order to further improve the connection stability between the slide positioning and feeding device 4 and the slide collecting device 6, a magnetic adsorption structure (not shown) can be added between the two.

[0063] The working principle of the slide collecting device 6 is as follows: Under the action of gravity, the slide 100 can slide down along the first inclined slide 44 and enter the second inclined slide 61 in the slide collecting device 6, and then slide onto the lifting handle 63. The second motor 64 and the lead screw slider transmission assembly 65 can drive the lifting handle 63 to rise and fall in the slide collecting groove 62. When the lifting handle 63 rises, it can move the slide 100 above the first one-way check block 66 and the second one-way check block 67. Since the first one-way check block 66 and the second one-way check block 67 can rotate, they will not affect the rise of the slide 100. However, when the lifting handle 63 descends, the first one-way check block 66 and the second one-way check block 67 will block the descent of the slide 100 to prevent the slide 100 from falling back onto the second inclined slide 61. At the same time, the first one-way check block 66 and the second one-way check block 67 can also support all the slides 100 above. By repeating the above steps, slides 100 can be inserted one by one from the bottom into the slide collection slot 62. Since the slides 100 are generally very thin and are stored in layers in the slide collection slot 62, a typical slide collection slot 62 can store dozens or even hundreds of slides 100, providing a large capacity and significantly reducing the frequency and labor intensity of workers handling the slides. Furthermore, it allows for a first-in, first-out system, with the first-printed slide number on top of the last collected slides 100. Once the slot is full, the entire collection is removed without needing to adjust the placement order of the slides 100.

[0064] Reference Figures 21 to 24 The medical slide marking machine also includes a purification system 7, which comprises a dust collection hood 71, a manifold hood 72, an intermediate air duct 73, a primary filter element 74, a secondary filter element 75, a tertiary filter element 77, and a first fan 76. The dust collection hood 71 collects dust and odors generated by the laser marking device 5. The primary filter element 74 is disposed on the inner wall of the dust collection hood 71. The first fan 76 is disposed on the outer wall of the dust collection hood 71. One end of the intermediate air duct 73 is connected to the first fan 76, and the other end is connected to the manifold hood 72. The secondary filter element 75 is disposed inside the intermediate air duct 73. The first fan 76 draws air from the dust collection hood 71 and sends the drawn air into the intermediate air duct 73 and the manifold hood 72. The manifold hood 72 combines the cooling airflow from the laser marking device 5 with the airflow generated by the first fan 76. The manifold hood 72 has an air outlet 721. Figure 27 The three-stage filter element 77 is located inside the air outlet 721 of the manifold 72.

[0065] In this embodiment, the primary filter element 74 is a dust filter, the secondary filter element 75 is an odor filter, and the tertiary filter element 77 is an odor filter. When the medical slide marking machine is operating, the generated dust and odor rise into the dust collection hood 71. The first fan 76 is in the activated state, drawing away the dust and odor from the dust collection hood 71. The primary filter element 74 filters out most of the dust and also filters out a small portion of the odor (generally 10-20%). A very small portion of the dust and a considerable portion of the odor enter the intermediate duct 73. The secondary filter element 75 filters out the remaining dust again and removes most of the odor; only a small portion of the odor can pass through these two filters. Adding only the tertiary filter element 77 would not be sufficient to remove the odor more efficiently and thoroughly, because the more adhesive odor molecules have already been adsorbed and filtered out by the secondary filter element 75, and the escaping odor molecules have poor adhesion. This application also includes a manifold 72, which allows the airflow that has undergone double filtration to enter the manifold 72. At the same time, the heat dissipation airflow from the laser marking device 5 also enters the manifold 72. The laser marking device 5 generates a large amount of heat, and the heat dissipation airflow has a relatively high temperature. After the two airflows merge, they can heat the airflow after double filtration. The odor molecules in this airflow increase in temperature, activity, and adhesion, making it easier for them to be adsorbed onto the third-stage filter 77 when passing through it. The odor molecules are further filtered efficiently, and the airflow coming out of the air outlet 721 of the manifold 72 will be cleaner.

[0066] The laser marking device 5 is equipped with a dedicated fan for heat dissipation, drawing out hot air. In this embodiment, the hot airflow is then directed into the manifold 72.

[0067] Reference Figure 26 The airflow from the intermediate duct 73 enters the manifold 72 from top to bottom, while the cooling airflow from the laser marking device 5 enters the manifold 72 from bottom to top. Utilizing the principle of hot air rising and cold air falling, the mixing effect of the two airflows is increased, improving heating efficiency. The first fan 76 is a turbine fan, which is small in size, has a large air volume, and strong suction.

[0068] Example 2:

[0069] The glass slides are made of glass and are fragile. When placing the glass slides into the slide loading box or pushing the slides with the slide pusher, there is still a chance that the glass slides will break. Once broken, it may affect the stable operation of the entire equipment and the machine needs to be stopped in time to clean up the fragments.

[0070] Reference Figure 28 and Figure 29The medical slide marking machine described in this embodiment differs from that in Embodiment 1 in that a cleaning brush 37 is also provided at the front end of the horizontal drive block 32. The cleaning brush 37 moves horizontally along with the horizontal drive block 32. The mounting frame 1 is provided with a fragment collection platform 17, and the front end of the fragment collection platform 17 is provided with a fragment guide groove 18. A fragment storage box 19 is provided below the fragment collection platform 17. When fragments are generated, they fall onto the fragment collection platform 17, and the slide pusher 33 on the horizontal drive block 32 has no slide to push. The cleaning brush 37 on the horizontal drive block 32 pushes the fragments on the fragment collection platform 17 forward, and then into the fragment guide groove 18. The fragments fall into the fragment storage box 19 along the fragment guide groove 18, thereby realizing the fragment processing and collection function without stopping the machine and without affecting the stable operation of the entire device.

[0071] Reference Figure 28 The position of the first position sensor 311 is also different; in this embodiment, it is positioned above the debris collection platform 17, and both can detect the position of the horizontal drive block 32. Other structures and beneficial effects are the same as in Embodiment 1, and will not be repeated here.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
