Description

Technical Field

[0001] This utility model relates to the field of automated testing of medical devices, and in particular to an inkjet printing device for printing markings on glass slides. Background Technology

[0002] In automated testing of medical devices, it is often necessary to print identification information on glass slides for sample tracking and management. Compared to thermal transfer printing, inkjet printing offers faster printing speeds and more convenient and quicker consumable (ink cartridge) replacement. However, practical applications have revealed drawbacks. In intermittent operation scenarios, the printhead of an inkjet printer exposed to air can cause the ink to evaporate and dry out. The longer the downtime, the greater the probability of the printhead becoming clogged due to drying, leading to print line breaks or ink splattering upon restarting.

[0003] In existing technologies, methods such as daily manual cleaning or covering the printhead with a moisturizing sponge can prevent the printhead from clogging due to intermittent operation. However, these methods undoubtedly increase the workload or, due to the uncontrollable pressure of the moisturizing sponge in sealing contact with the printhead, can easily damage the printhead surface. Furthermore, they still cannot simultaneously address the need for automatic unclogging and cleaning, which seriously affects the printing reliability and equipment efficiency. Utility Model Content

Detailed Implementation

[0019] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] like Figures 1-7 As shown, this utility model provides an inkjet printing device for printing markings on glass slides, which includes a glass slide transport mechanism, a printing mechanism, and an anti-blocking mechanism. The glass slide transport mechanism is used to transport glass slides 000 to the printing mechanism, and the printing mechanism prints marking information on the glass slides 000 for subsequent tracking and management of the glass slide samples. The anti-blocking mechanism is located below the printing mechanism and is used to automatically block or clear the printhead of the printing mechanism when the printing mechanism stops.

[0021] The slide transport mechanism includes a linear transport drive module (not shown) with the drive direction along X and a slide tray 800 connected to the drive end of the linear transport drive module. The slide 000 is placed on the slide tray 800 and is transported to the printing mechanism by the linear transport drive module.

[0022] The linear transport drive module used in this utility model is existing technology and can be a linear slide module, a lead screw drive module, etc., which will not be described in detail here.

[0023] The slide tray 800 is a long rectangular block, with its top surface sinking downwards to form a long rectangular receiving compartment. The two sides along the length of the slide tray 800 become the two side guards 8001 of the receiving compartment. Each of the two side guards 8001 extends towards the center of the slide tray 800 and sinks downwards to form a tray step surface 801 for holding the slide. The length of each tray step surface 801 is the same as the length of the receiving compartment. The slide 000 is placed on the two tray step surfaces 801. In order to facilitate the removal and placement of the slide, the width between the two side guards 8001 is slightly larger than the width of the slide 000.

[0024] As a preferred option, to further ensure the stability of the slide 000 on the slide tray 800, a pair of slide clamping components are also provided on the slide tray 800.

[0025] Each slide clamping assembly includes a clamping plate 900 and a clamping spring 906. The clamping plate 900 is a strip with a length greater than the width of the slide tray 800. One end of the clamping plate 900 is provided with a clamping plate stepped surface 901 and a clamping plate retaining edge 902 in sequence along its length direction. The clamping plate retaining edge 902 is located on the outer side and its top surface is higher than the top surface of the clamping plate stepped surface 901. A clamping plate guide rail 904 is fixedly connected to the bottom surface of each clamping plate 900 along its length direction. Each clamping plate 900 has a clamping spring hole 905 near the clamping plate retaining edge 902. The clamping spring hole 905 is parallel to the length direction of the clamping plate 900, and one end of the clamping spring 906 is placed in the clamping spring hole 905.

[0026] Furthermore, a handhold 903 is provided on the other end of the clamp 900 opposite to the clamp edge 902, protruding from the upper surface of the clamp 900, to facilitate pushing and pulling the clamp 900.

[0027] To install the slide clamping assembly, a mounting groove 802 is symmetrically provided at both ends of the slide tray 800 along its length direction. Each mounting groove 802 is located within the length range of the tray step surface 801. The length direction of each mounting groove 802 is perpendicular to the length direction of the slide tray 800, that is, the mounting groove 802 is set along the Y direction, and its length is greater than the width of the aforementioned receiving compartment. Each mounting groove 802 has an opening at one end along its length direction to facilitate the movement of the clamping plate 900 along the Y direction.

[0028] Furthermore, a slider 803 is fixedly attached to the bottom surface of each mounting groove 802.

[0029] Each clamping plate 900 is slidably installed in each mounting groove 802 along the Y direction. Specifically, the clamping plate guide rail 904 on the bottom surface of each clamping plate 900 is slidably connected to the slider 803 in the mounting groove 802. The other end of the clamping spring 906 in the clamping plate 900 is connected to the inner wall of the mounting groove 802. When the clamping plate 900 is placed in the mounting groove 802, the clamping plate step surface 901 and the tray step surface 801 are on the same horizontal plane to facilitate the placement of the slide. The clamping plate edge 902 and the upper surface of the slide tray 800 are on the same horizontal plane. When the slide tray 800 of this utility model is in its normal state, under the elastic support of the clamping spring 906, there is an appropriate distance between the outer side of the clamping plate edge 902 of each clamping plate 900 and the inner wall of the opposite mounting groove 802, and the distance between the inner side of the clamping plate edge 902 and the inner wall of the opposite storage side edge 8001 is equivalent to the width of the slide 000. When the clamping plate 900 is pushed along the Y-axis towards the inner wall of the mounting groove 802, the clamping spring 906 is compressed, and the clamping plate side 902 moves synchronously. The distance between the clamping plate 902 and the inner wall of the opposite side side 8001 is approximately the same as the distance between the inner walls of the two side side 8001s, making it convenient to pick up and put in the slide 000. After the slide 000 is placed in, the pushing force applied to the clamping plate 900 disappears, and the clamping spring 906 causes the clamping plate 900 to spring back to the normal position of the slide tray 800. At this time, the slide 000 is clamped between the clamping plate side 902 and the inner wall of the side side 8001. That is, the clamping spring 906 provides clamping force to make the clamping plate side 902 and its opposite side side 8001 clamp the slide, thereby achieving the stability of the slide 000 during operation.

[0030] Preferably, to increase the operational stability of each glass slide clamping assembly, each clamping plate 900 in the mounting groove 802 is symmetrically provided with two clamping spring holes 905, and each clamping spring 906 is installed in the two clamping spring holes 905 of each clamping plate 900.

[0031] The printing mechanism is located on the transport path of the glass slide 000 and includes a fixed bracket and an inkjet printer 200. The fixed bracket includes a bracket back plate 101 arranged vertically in the vertical direction and a transverse panel 102 connected horizontally and vertically to the bracket back plate 101 in the Y direction. A panel slot 103 is formed on the front end of the transverse panel 102 away from the bracket back plate 101. The inkjet printer 200 is prior art. A printhead 201 for printing preset marking information onto the glass slide is disposed on the bottom surface of the inkjet printer 200. The inkjet printer 200 is fixed on the transverse panel 102, and the printhead 201 is located above the panel slot 103 and within the area enclosed by it.

[0032] When the linear transport drive module moves the slide tray 800 to the printing mechanism, the position of the pre-printed marking information on the slide 000 on the slide tray 800 is exactly below the printhead 201, so as to facilitate accurate printing.

[0033] Preferably, a side baffle 104 is also fixed vertically upward on one side of the support back plate 101, and the side of the inkjet printer 200 near the side baffle 104 is connected to the side baffle 104 to increase its stability.

[0034] The anti-clogging mechanism is located below the horizontal panel 102 and on the side near the panel slot 103. The anti-clogging mechanism includes a horizontal movement drive assembly 300, a lifting drive assembly 400, a waste ink cartridge 500, a floating sealing assembly 600, and a mounting platform 700 for mounting the various components.

[0035] The lateral movement drive assembly 300 includes a stepper motor 301, a synchronous belt 302, two synchronous pulleys 303, and a lateral guide rail 304.

[0036] A transverse guide rail 304 is mounted on one side of the upper surface of the mounting platform 700 along the X direction. The fixed end of the stepper motor 301 is fixed to the lower surface of the mounting platform 700, and its driving end passes through the mounting platform 700 and connects to a synchronous pulley 303. Another synchronous pulley 303 is mounted on the mounting platform 700. The two synchronous pulleys 303 are coaxially arranged opposite each other along the X direction. A synchronous belt 302 is sleeved on the two synchronous pulleys 303. The synchronous belt 302 is located on one side of the transverse guide rail 304, and the synchronous belt 302 between the two synchronous pulleys 303 is parallel to the transverse guide rail 304. The bottom surface of the support plate 701 is slidably connected to the transverse guide rail 304. One side of the support plate 701 is fixed or snapped to the synchronous belt 302 between the two synchronous pulleys 303. When the stepper motor 301 drives the synchronous pulley 303 to rotate, the synchronous belt 302 simultaneously drives the support plate 701 to reciprocate along the transverse guide rail 304. The bearing plate 701 is a long rectangular plate whose length extends horizontally away from the support back plate 101.

[0037] As a preferred embodiment, to further precisely control the moving distance of the support plate 701, a photoelectric limit sensor 306 is provided on the lower surface of the mounting platform 700, at each end of the transverse guide rail 304 along its length. A transverse limit sheet metal 305 is provided on the side of the support plate 701 near the glass slide transport mechanism. The lower end of the transverse limit sheet metal 305 has a folding part facing the photoelectric limit sensor 306, and the folding part is located between the two photoelectric limit sensors 306 on the mounting platform 700. When the folding part of the transverse limit sheet metal 305 moves to either photoelectric limit sensor 306, the support plate 701 stops.

[0038] The lifting drive assembly 400, waste ink cartridge 500, and floating sealing assembly 600 are mounted on the support plate 701. To facilitate the installation of other components, a lifting back plate 703 is vertically mounted on the back of the support plate 701 away from the bracket back plate 101. The lifting back plate 703 is opposite to and parallel to the bracket back plate 101.

[0039] The lifting drive assembly 400 includes a lead screw stepper motor 401. The fixed end of the lead screw stepper motor 401 is connected to the lower surface of the support plate 701, and its driving end passes through the support plate 701 and is connected to a lead screw nut 402. A lifting fixing block 403 is fixedly connected to the lead screw nut 402. The lifting fixing block 403 is a rectangular block. One end of the block facing the lifting guide rail 404 has a clearance hole to avoid the driving end of the lead screw stepper motor 401. The driving end of the lead screw stepper motor 401 passes through the clearance hole of the lifting fixing block 403, so that the bottom end of the lifting fixing block 403 is fixedly connected to the lead screw nut 402. The lifting back plate 703 is mounted on the side of the lifting back plate 703 facing the horizontal panel 102 along the Z direction. The lifting fixing block 403 is slidably connected to the lifting guide rail 404 away from the back of the support back plate 101.

[0040] As a preferred embodiment, to further precisely control the lifting distance of the lifting fixed block 403, the lifting back plate 703 is located away from the back of the lifting guide rail 404, and a photoelectric limit sensor 306 is provided at each end of the lifting guide rail 404 along its length. A lifting limit sheet metal 405 is connected to one side of the lifting fixed block 403. The lifting limit sheet metal 405 is a rectangular strip, and its tail end has a folded part that flips towards the photoelectric limit sensor 306. When the folded part of the lifting limit sheet metal 405 is driven by the lead screw stepper motor 401 to any photoelectric limit sensor 306 on the lifting back plate 703, the lifting fixed block 403 stops.

[0041] The lifting and fixing block 403 is connected to the floating sealing assembly 600 on the front side facing the printhead 201. The floating sealing assembly 600 is used to seal the printhead 201 when the inkjet printer 200 is stopped to prevent it from drying out in the air. It includes a sealing head fixing seat 601, a sealing head 602, and a sealing spring 603.

[0042] The lower end of the sealing head fixing seat 601 is strip-shaped, and its upper end protrudes in the Y direction towards the nozzle 201 to form a rectangular fixing top block 6011. The upper surface of the fixing top block 6011 is recessed downward to form a receiving groove 6012. The lower end of the sealing head fixing seat 601 is connected to the front side of the lifting fixing block 403 facing the bracket back plate 101, and the fixing top block 6011 is located exactly below the panel groove 103.

[0043] The receiving groove 6012 of this utility model is a long rectangle, and its length direction is set along the Y direction. The bottom center of the receiving groove 6012 is recessed to form a sealing spring limiting hole 6013. Floating limiting ports 6014 are opened on both sides of the groove along the X direction. The floating limiting ports 6014 on the two sides are symmetrically designed, and each floating limiting port 6014 is set along the Z direction in length direction.

[0044] Preferably, on both sides of the receiving groove 6012 along the X direction, two floating limit ports 6014 are symmetrically arranged side by side, and the inner walls of both ends of each floating limit port 6014 along its length direction are arc-shaped transition surfaces.

[0045] The sealing head 602 has a T-shaped cross-section, including a sealing base 6021 and a sealing top plate 6022 located on the top surface of the sealing base. Both are long rectangles, and their lengths extend along the Y direction towards the nozzle 201. The length of the sealing base 6021 is smaller than the length of the receiving groove 6012, while the length of the sealing top plate 6022 is larger than the length of the receiving groove 6012. The bottom surface of the sealing base 6021 has a sealing spring hole 6023 along the Z direction, and the sealing spring 603 is placed in the sealing spring hole 6023. The side surface of the sealing base 6021 has two pin holes arranged in parallel along the X direction. A pin 6024 is fixedly connected in each pin hole, and the two ends of each pin 6024 are located outside the pin hole. A silicone pad 6025 is detachably connected to the upper surface of the sealing top plate 6021 facing the nozzle. The size and shape of the silicone pad 6025 are compatible with the size of the nozzle 201. In this utility model, the silicone pad 6025 is illustrated as a long rectangle.

[0046] Preferably, the length and width of the silicone pad 6025 are slightly larger than those of the nozzle 201 to ensure complete coverage and sealing of the nozzle 201.

[0047] Preferably, to facilitate subsequent replacement of the silicone pad 6025, the upper surface of the sealing top plate 6021 is recessed downward to form a top plate concave surface for loading the silicone pad 6025, and the silicone pad 6025 is snapped or pasted onto the top plate concave surface.

[0048] To allow the sealing base 6021 to slide along the Z-direction into the receiving groove 6012, the other end of the sealing spring 603 in the sealing base 6021 is connected to the sealing spring limiting hole 6013, and the two ends of each pin 6024 are correspondingly located in the floating limiting port 6014. The sealing top plate 6022 is located above the receiving groove 6012, and the silicone pad 6025 on the sealing top plate 6022 is correspondingly located below the panel groove 103.

[0049] When slide 000 is printed at printhead 201, the lifting drive assembly causes the silicone pad 6025 to descend and avoid being positioned below the slide tray 800.

[0050] When the sealing spring 603 is not in working state, the sealing head 602 is supported upward by the sealing spring 603, so that each pin 6024 abuts against the upper end of the floating limit port 6014. When the glass slide 000 is printed and the inkjet printer 200 is in a stopped state, the lateral displacement drive component drives the sealing head 602 to move below the printhead 201. The lifting drive component continues to drive the silicone pad 6025 of the sealing head 602 to rise and seal against the printhead 201. At the same time, the sealing spring 603 is simultaneously subjected to downward pressure. When its compression deformation is in the working state, the sealing head 602 also descends. Each pin 6024 also descends and abuts against the lower end of the floating limit port 6014. That is, the floating distance of the sealing head 602 is limited by the length of the floating limit port 6014 to control the density pressure of the sealing head 602. This ensures the sealing effect of the silicone pad 6025 on the printhead 201 without excessive pressure that could damage the printhead 201, ultimately achieving a long-term and stable working effect of the floating sealing component 600.

[0051] Furthermore, a waste ink cartridge 500 is also fixed to the side of the sealing head fixing seat 601 near the glass slide transport mechanism by bolts. That is, the sealing head fixing seat 601 and the waste ink cartridge 500 are arranged sequentially along the X direction and are separated by an appropriate clearance. The waste ink cartridge 500 is a box-shaped object, and its top surface has an ink inlet 501 that is compatible with the size of the print head 201. When the sealing spring 603 is in the working state, the top surface of the waste ink cartridge 500 is not higher than the top surface of the silicone pad 6025.

[0052] In this utility model, the ink inlet 501 is illustrated by an example of a long rectangular inlet.

[0053] The printhead 201 of the inkjet printer 200 can automatically eject a certain amount of ink. Before restarting the printer after it has been stopped, or during routine maintenance, the horizontal movement drive component moves the ink inlet 501 of the waste ink cartridge 500 to below the printhead 201. The lifting drive component then moves the ink inlet 501 of the waste ink cartridge 500 to the printhead 201, and the printhead 201 ejects a certain amount of ink into the waste ink cartridge 500, thereby clearing the printhead and achieving self-maintenance.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
