Summary of the invention

[0004] The purpose of the present invention is to provide a multi-station automatic laser marking device to solve the above-mentioned deficiencies in the prior art.

[0009] As a further description of the above technical solution: a resistance structure, whose power input end is connected to the transmission structure, and whose power output end is connected to the long-distance clamping structure, wherein the resistance structure is provided with resistance rods which are slidably inserted at both ends of the tissue wax block marking plate, and a slide plate is fixedly connected to one end of the resistance rod and a long-distance clamping plate is installed, and the other end of the resistance rod is slidably and resistantly connected to a trapezoidal resistance plate in a right-angle trapezoidal shape, so that the tissue wax block marking plate slides up and down, and the resistance rod and the trapezoidal resistance plate are slidably resistant to each other, thereby driving the relative movement of the two groups of slides and the long-distance clamping plate on the surface of the tissue wax block marking plate, thereby realizing the clamping and release of the marking object.

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] See also Figure 1-Figure 7 The embodiment of the present invention provides a technical solution for a multi-station automatic laser marking device: comprising: a marking box 1 for laser marking medical embedding boxes, slices, reagent kits, and culture media, and a protective door 2 that is flipped open from top to bottom is provided on the surface of the marking box 1:

[0043] It also includes a transmission structure fixedly installed at the connection position between the protective door 2 and the marking box 1 for rotation. The transmission structure transmits the power of rotation when the protective door 2 is opened and closed to the long-distance clamping structure, the short-distance clamping structure and the linkage structure through the meshing between the gear and the toothed plate 22. The sliding contact connection between the trapezoidal contact plate 14 in the shape of a right-angled trapezoid and the contact rod 17 provided in the contact structure is realized to achieve the clamping of the two groups of long-distance clamping plates 20 provided in the long-distance clamping structure on the two ends of the long ends of the marking object to be marked. At the same time, the linkage structure drives the short-distance clamping structure to clamp the two ends of the short ends of the marking object, thereby realizing the power input to the long-distance clamping structure and the short-distance clamping structure through the opening and closing of the protective door 2, and the marking object is automatically clamped and fixed for use in laser marking.

[0044] In another embodiment provided by the present invention, a transmission structure is installed at the connection between the two ends of the inner bottom of the protective door 2 and the marking box 1, so that the protective door 2 can be flipped from top to bottom, and the power generated during the flipping can be transmitted to the long-distance clamping structure and the short-distance clamping structure through the resistance structure to automatically clamp and fix the marking object.

[0045] The transmission structure includes: a transmission shaft 11 fixedly installed at both ends of the bottom of the inner side of the protective door 2, one end of the transmission shaft 11 is rotatably connected to the two ends of the bottom of the marking box 1, and the other end of the transmission shaft 11 is rotatably inserted in the marking box 1 and fixedly connected to a rotatable transmission gear 13, one side of the transmission gear 13 is meshedly connected with a tooth plate 22, and the top of the tooth plate 22 is fixedly connected to the two ends of the tissue wax block marking plate 10, so that the rotation of the transmission gear 13 can drive the meshed tooth plate 22 to slide up and down at the bottom of the marking box 1, thereby driving the tissue wax block marking plate 10 to adjust the upper and lower positions in the marking groove 12.

[0046] In another embodiment provided by the present invention, the resistance structure has a power input end connected to the transmission structure, and a power output end connected to the long-distance clamping structure. The resistance structure is provided with a resistance rod 17 that is slidably inserted at both ends of the tissue wax block marking plate 10, and a slide plate 18 is fixedly connected to one end of the resistance rod 17 and a long-distance clamping plate 20 is installed, and the other end of the resistance rod 17 is slidably and resistantly connected to a trapezoidal resistance plate 14 in a right-angle trapezoidal shape, so that the resistance rod 17 and the trapezoidal resistance plate 14 slide up and down, and the relative movement of the two groups of slide plates 18 and the long-distance clamping plate 20 on the surface of the tissue wax block marking plate 10 is driven by the sliding of the tissue wax block marking plate 10, thereby clamping and releasing the marking object.

[0047] The resistance structure includes: a trapezoidal resistance plate 14 in a right-angled trapezoidal shape fixedly installed at both ends of the bottom of the marking box 1, and the inclined surface of the trapezoidal resistance plate 14 faces the two ends of the tissue wax block marking plate 10, and a slide groove 15 is opened on both sides of the trapezoidal resistance plate 14, and a rotating wheel 28 is slidably connected in the slide groove 15. The rotating wheel 28 is rotatably installed at both ends of the inner side of the slide 16, and the slide 16 is slidably connected to the inclined surface of the trapezoidal resistance plate 14. The slide 16 is fixedly connected to one end of the resistance rod 17, and the other end of the resistance rod 17 is slidably inserted into the two ends of the tissue wax block marking plate 10 and fixedly connected to the slide plate 18 set in the long-distance clamping structure.

[0048] In another embodiment provided by the present invention, a long-distance clamping structure and a short-distance clamping structure are arranged at the long end of the surface of the tissue wax block marking plate 10, and the power input end of the long-distance clamping structure is connected to the resistance structure. The resistance rod 17 arranged in the resistance structure is used to randomly check the inside of the tissue wax block marking plate 10, thereby driving the slide plate 18 and the long-distance clamping plate 20 to slide relative to each other on the surface of the tissue wax block marking plate 10.

[0049] In another embodiment provided by the present invention, the short-distance clamping structure is arranged at the short end of the surface of the tissue wax block marking plate 10, and the power input end of the short-distance clamping structure is connected to the middle section of the resistance rod 17, so that the resistance rod 17 first pushes and clamps the long-distance clamping structure and then clamps the short end, so that the marking object is first fixed in the middle position of the surface of the tissue wax block marking plate 10 by the long-distance clamping structure and then the other two sides are clamped and fixed.

[0050] The long-distance clamping structure includes: a slide rail 21 transversely opened on the surface of the tissue wax block marking plate 10, a slide plate 18 is slidably connected in the slide rail 21, the bottom end of the slide plate 18 is fixedly connected to one end of the abutment rod 17, and the surface of the slide plate 18 is connected to the long-distance clamp plate 20 through a compression spring 19;

[0051] The short-distance clamping structure includes: a slide rail 21 opened on the surface of the tissue wax block marking plate 10 in a cross shape with the transverse slide rail 21, and a short-distance clamping plate 9 is slidably connected in the slide rail 21;

[0052] When marking a marking object with a small difference in length and width, the difference in clamping force on the four sides can be reduced through the stepped structure between the long-distance clamping structure and the short-distance clamping structure. When fixing a marking object with a large difference in length and width, the long-distance clamping plate 20 first fixes the marking object in the middle of the surface of the tissue wax block marking plate 10, and then cooperates with the compression spring 19 between the slide plate 18 and the long-distance clamping plate 20 to provide the difference between the length and width, thereby reducing the difference in clamping force on the four sides of the marking object and better clamping the marking object.

[0053] In another embodiment provided by the present invention, a linkage structure is provided on the surface of the resistance rod 17 and connected to the short-distance clamping structure, which converts the lateral force generated by the resistance rod 17 into a longitudinal force through the linkage gear 27, thereby realizing a power source driving transmission in multiple directions, thereby clamping the four sides of the marking object on the surface of the tissue wax block marking plate 10 at the same time.

[0054] The linkage structure includes: a baffle 24 fixedly installed on the middle end of the surface of the resistance rod 17, and a slip ring 25 slidably connected to the surface of the resistance rod 17, one side of the slip ring 25 is fixedly connected to one end of an L-shaped connecting rod 23, and the other end of the connecting rod 23 is fixedly connected to a linkage rack 30, the linkage rack 30 is meshed with the upper half of one side of the linkage gear 27, and the lower half of the other side of the linkage gear 27 is meshed with the changing rack 26, and the top of the changing gear is fixedly connected to the short-distance splint 9, and the linkage gear 27 is rotatably installed in the tissue wax block marking plate 10 through a torsion spring shaft 31, so as to realize the extension and retraction of the resistance rod 17 and drive the linkage rack 30 to rotate the linkage gear 27 through the L-shaped connecting rod 23, and drive the two groups of short-distance splints 9 to slide relative to each other through the changing rack 26.

[0055] In another embodiment provided by the present invention, the height of the linkage gear 27 is greater than the added thickness of the linkage rack 30 and the changing rack 26, and the linkage rack 30 and the changing rack 26 are respectively meshed with the top and bottom of the linkage gear 27, and at the same time, the linkage rack 30 and the changing rack 26 are arranged at a vertical angle, thereby realizing the conversion of the lateral force into the longitudinal force.

[0056] In another embodiment provided by the present invention, the trapezoidal abutment plate 14 has a right-angle trapezoidal cross section, and the inclined surface faces the two ends of the tissue wax block marking plate 10;

[0057] A glass slide laser marking machine 32 which can be used alone is detachably mounted on one side of the marking box 1. The glass slide laser marking machine 32 can be used in combination with the marking box 1, or the glass slide laser marking machine 1 can be used alone.

[0058] In another embodiment provided by the present invention, the control structure includes a network component and a power supply component 4 arranged outside the marking box 1, and the network component 3 is configured as a scannable QR code, which can be connected to a mobile phone or a computer after scanning the code to join the Internet or a local area network to control the marking box 1.

[0059] In another embodiment provided by the present invention, preferably, the control structure also includes an illumination light source 6 for providing illumination arranged inside the marking box 1, the illumination light source 6 is installed at the top of the marking box 1, and a robotic arm 7 is also installed at the top of the marking box 1, a laser light source 8 for laser marking is installed at one end of the robotic arm 7, and a heat sink 5 is installed in the marking box 1 for dissipating heat inside the marking box 1.

[0060] This equipment can be used for marking on plastic, metal, glass, wood and other materials, mainly used for embedding number marking, slide number marking, reagent bottle number marking, etc.

[0061] At the same time, this equipment is intelligent: it can be controlled by mobile phones or computers, and can also be remotely controlled; it is easy to operate and does not take up space; it is equipped with a voice assistant for easy operation; it has a wide range of uses, not just limited to embedding boxes and slice numbering; this equipment is simple and practical, not only can it meet the needs of pathological slice and embedding box marking, but can also be used for reagent kits, culture media, experimental glassware, etc.

[0062] When the marking machine is used, the embedding boxes, slices, reagent kits, culture media, experimental glassware, etc. that need to be marked are placed on an independent fixed base, and the protective door 2 of the marking box 1 is opened. During the opening process of the protective door 2 flipping from top to bottom, the transmission shaft 11 rotatably installed between the two ends of the inner bottom and the marking box 1 rotates. The marking box 1 and the transmission shaft 11 are rotatably connected, and the transmission shaft 11 and the protective door 2 are fixedly connected. Therefore, when the protective door 2 is flipped, the protective door 2 will rotate with the transmission shaft 11 as the center of the circle and drive the transmission shaft 11 to rotate. During the rotation of the transmission shaft 11, the transmission gear 13 fixedly connected to the transmission shaft 11 on both sides of the marking box 1 is driven to rotate counterclockwise. While the transmission gear 13 rotates counterclockwise, it drives the toothed plate 22 meshed with the inner side to be lifted upward along with the counterclockwise rotation of the transmission gear 13. The toothed plate 22 is fixedly installed at the middle position of both ends of the tissue wax block marking plate 10. Therefore, when the gear drives the toothed plate 22 to be lifted upward, it also drives the tissue wax block marking plate 10 to be lifted upward in the marking groove 12, thereby ejecting the tissue wax block marking plate 10 from the marking groove 12.

[0063] When the tissue wax block marking plate 10 is lifted upward in the marking groove 12, the resistance rods 17 movably connected at both ends are restricted by the bottom slide 16 and the slide groove 15 bracket and are pulled out from the tissue wax block marking plate 10 to both ends, thereby driving the two sets of slide plates 18 on the surface of the tissue wax block marking plate 10, which are slidably connected in the slide rail 21 and fixedly connected to the top of the resistance rods 17 at the bottom, to slide on the surface of the tissue wax block marking plate 10 to both ends, and at this time, the clamping force on the surface of the tissue wax block marking plate 10 in the long-distance direction is released;

[0064] At this time, due to the extension of the abutment rod 17, the torsion spring shaft 31 in the linkage gear 27 is free from restriction and rotates back. At the same time, the connecting rod 23 drives the meshing linkage gear 27 to rotate clockwise as the abutment rod 17 is pulled outward, thereby pulling the short-distance clamping plate 9, which is meshed with the changing rack 26 on one side of the linkage gear 27, to gradually release the clamping force.

[0065] At this time, after the tissue wax block marking plate 10 is completely lifted out of the marking groove 12, the previously marked objects together with the base can be taken out, the marked objects on the base can be removed and new marked objects can be placed, and the base with the marked objects placed can be directly placed on the surface of the tissue wax block marking plate 10. After the marked objects are placed on the surface of the tissue wax block marking plate 10, the protective door 2 can be directly closed;

[0066] When the protective door 2 is closed, the protective door 2 drives the transmission gear 13 to rotate clockwise through the transmission shaft 11. The clockwise rotation of the transmission gear 13 drives the meshing toothed plate 22 to slide downward, thereby driving the tissue wax block marking plate 10 to move downward in the marking groove 12. When the tissue wax block marking plate 10 moves downward, the resistance rods 17 slidably inserted at both ends of the tissue wax block marking plate 10 will also slide downward accordingly. At the same time, the bottom end of the resistance rod 17 is attached to the surface of the trapezoidal resistance plate 14 and is slidably connected to the slide grooves 15 on both sides of the trapezoidal resistance plate 14 through the slide 16 and the rotating wheel 28. The trapezoidal resistance plate 14 is in a right-angled trapezoidal shape and faces the hypotenuse to the tissue wax block marking plate 10 and is slidably and resistively connected on the slide 16 and the bottom end of the resistance rod 17. The hypotenuse of the trapezoidal resistance plate 14 is from top to The spacing between the lower and tissue wax block marking plate 10 gradually decreases. Therefore, when the tissue wax block marking plate 10 slides downward, the bottom end of the resistance rod 17 slides and resists on the hypotenuse of the trapezoidal resistance plate 14. Limited by the size of the hypotenuse of the trapezoidal resistance plate 14, the top end of the resistance rod 17 is inserted into the tissue wax block marking plate 10, thereby driving the slide plate 18 fixedly connected above the top end of the resistance rod 17 to slide in the slide rail 21 toward the middle of the surface of the tissue wax block marking plate 10. During the movement of the two groups of slide plates 18 at both ends of the surface of the tissue wax block marking plate 10 approaching each other, the long-distance clamping plate 20 connected by the compression spring 19 on the surface of the slide plate 18 will contact the two ends of the long distance of the base on which multiple marking objects are placed, thereby clamping and fixing the multiple groups of marking objects on one side at a long distance;

[0067] At the same time, when the abutment rod 17 is inserted into the tissue wax block marking plate 10 to a certain extent, this extent is the difference between the long distance section and the short distance section of the clamping, which means that the clamping is first performed at one end of the long distance, and the bases of the multiple groups of marking objects are first clamped on the left and right sides and pushed to the middle position of the surface of the tissue wax block marking plate 10, and then the clamping of the short distance side is driven, and the marking object is first fixed at the middle position of the surface of the tissue wax block marking plate 10 by the long distance clamping structure, and then the other two sides are clamped and fixed;

[0068] After the resistance rod 17 is inserted to a certain extent, the slip ring 25 slidably connected to the surface of the resistance rod 17 cooperates with the baffle 24 fixedly installed on the surface of the resistance rod 17 to squeeze the buffer spring 29 arranged between the two. After the compression spring 19 is squeezed to a certain extent, when the resistance rod 17 continues to be inserted into the tissue wax block marking plate 10, the resistance rod 17 will pass through the baffle 24 and squeeze the L-shaped connecting rod 23 fixedly connected to one side of the slip ring 25 into the tissue wax block marking plate 10. During the insertion process of the connecting rod 23 into the tissue wax block marking plate 10, the linkage rack 30 connected to one end of the connecting rod 23 inserted into the tissue wax block marking plate 10 will drive the linkage gear 27 rotatably installed on the upper and lower sides of the tissue wax block marking plate 10 through the torsion spring shaft 31 to rotate counterclockwise, thereby driving the reversing rack 26 meshing and connected on the other side of the linkage gear 27 to drive the two sets of short-distance clamping plates 9 to approach each other, thereby fitting and clamping the other two sides of the base where multiple groups of marking objects are placed. After the four sides of the marking object are clamped, the protective door 2 is completely closed;

[0069] The laser light source 8 can be driven by the mechanical arm 7 to cooperate with the lighting light source 6 to perform laser marking on the surfaces of multiple groups of marking objects. During the marking process, a heat sink 5 is provided in the marking box 1 to dissipate heat inside the marking box 1, and a network component 3 is provided on the surface of the marking box 1. The network component 3 can be set to connect to a QR code. The user can connect to the marking box 1 by scanning the QR code, so as to control the marking box 1 with a mobile phone or other device. At the same time, the power supply component 4 of the marking box 1 is provided on the surface of the marking box 1, so that the marking box 1 can be quickly turned on and off.

[0070] This solution is equivalent to utilizing the rotational power generated by the opening and closing of the protective door 2 of the marking box 1, and dividing the power into multiple parts:

[0071] The first part drives the tissue wax block marking plate 10 to be lifted and lowered in the marking groove 12 through the meshing between the transmission gear 13 and the tooth plate 22;

[0072] In the second part, during the lifting and lowering process of the tissue wax block marking plate 10, the distance between the oblique side of the trapezoidal resistance plate 14 and the tissue wax block marking plate 10 is used to generate a resistance force on the resistance rod 17, and the two sets of long-distance clamping plates 20 arranged on the long sides are fitted together to clamp the marking object;

[0073] In the third part, a stepped clamping structure is set according to the distance difference between the long side and the short side, and the power generated by the long side during the clamping process is used by the meshing between the linkage gear 27, the linkage rack 30 and the direction-changing rack 26, so that the long-distance clamping plate 20 set on the long side and the short-distance clamping plate 9 set on the short side are moved synchronously, so as to realize the synchronous clamping of the four sides of the marking object, and the marking object is first fixed in the middle position of the surface of the tissue wax block marking plate 10 by the long-distance clamping structure, and then the other two sides are clamped and fixed;

[0074] The opening and closing movement of the protective door 2 provides power to the long-distance clamping structure and the short-distance clamping structure, and the transmission is carried out in a progressive manner. There is no need to clamp the marking object separately, and the force difference of the clamping on the four sides of the marking object can be reduced, making the operation more convenient.

[0075] Furthermore, when marking an object with a smaller difference between length and width, the difference in clamping force on the four sides can be reduced through the stepped structure between the long-distance clamping structure and the short-distance clamping structure. When fixing an object with a larger difference between length and width, the long-distance clamping plate 20 first fixes the object to be marked in the middle of the surface of the tissue wax block marking plate 10, and then cooperates with the compression spring 19 between the slide plate 18 and the long-distance clamping plate 20 to provide the difference between the length and width, thereby reducing the difference in clamping force on the four sides of the object to be marked and better clamping the object to be marked.

[0076] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
