[0001] The utility model relates to the technical field of electron microscope sample preparation, in particular to a bottom core embedding machine for an electron microscope. Background Technique

[0002] An electron microscope, abbreviated as EM, has become an essential and important tool in modern science and technology after more than fifty years of development. An electron microscope consists of three parts: an electron gun, a vacuum system, and a power supply cabinet. The electron lens is used to focus electrons and is the most important component in the electron microscope column. Generally, magnetic lenses are used, and sometimes electrostatic lenses are also used. It uses a spatially symmetric electric or magnetic field along the axis of the column to bend the electron trajectory towards the axis to form a focus. Its function is the same as that of an optical lens in an optical microscope to focus a light beam, so it is called an electron lens.

[0003] Since the bottom core carried during the electron microscope sample preparation process needs to be embedded at the bottom of the embedding material by hot melting, but the temperature is too high after production, it will cause damage during the handling process. For this reason, we propose a new type of bottom core embedding machine for an electron microscope.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Next, in combination with specific implementation cases and attached Figures 1-7 The present utility model will be further described, but the present utility model is not limited to these embodiments.

[0032] A bottom core embedding machine for an electron microscope, comprising a base 1. A processing table 2 is provided on the top of the base 1, and the processing table 2 is fixedly attached to the upper surface of the base 1. A feeding groove 6 is embedded at the top of the processing table 2, and the feeding groove 6 is used for placing the embedding material of the bottom core. An installation groove hole communicating with the inner cavity is opened at the top of the processing table 2, and the feeding groove 6 is fixedly embedded inside the installation groove hole. A through hole communicating with the inner cavity of the processing table 2 is opened at the top of the feeding groove 6. A hot-melt base 3 is slidably arranged in the inner cavity of the feeding groove 6, and the shape of the hot-melt base 3 corresponds to that of the feeding groove 6, so that the hot-melt base 3 moves up and down in the inner cavity of the feeding groove 6.

[0033] A heating sleeve 18 is fixedly installed at the bottom of the hot-melt base 3. A groove 31 is opened at the top of the heating sleeve 18, and a heater 30 is fixedly embedded inside the groove 31. The top of the heater 30 is in the same plane as the top of the heating sleeve 18. The heater 30 is heated by the electric heating wire arranged inside, and the heater 30 is electrically connected to an external power supply through a wire. The hot-melt base 3 is fixedly attached to the top of the heating sleeve 18, so that the hot-melt base 3 is attached to the top of the heater 30.

[0034] A displacement component for driving the heating sleeve 18 to move longitudinally is arranged in the inner cavity of the base 1. The position of the heating sleeve 18 is adjusted through the displacement component, so that the heating sleeve 18 drives the hot-melt base 3 to move to a suitable adjusted feeding position. A pressing cap 8 for pressing the bottom core is arranged above the feeding groove 6. Supporting plates 4 for supporting the bottom core are symmetrically arranged on both sides of the feeding groove 6. A linkage mechanism for driving the supporting plates 4 and the pressing cap 8 to move simultaneously is arranged on the processing table 2. Through the linkage mechanism, the pressing cap 8 moves while the two supporting plates 4 move relatively.

[0035] When making a sample for an electron microscope, first, the displacement component is used to drive the heating sleeve 18 to drive the hot-melt base 3 to move inside the feeding groove 6. After the hot-melt base 3 is adjusted to a suitable feeding position, the bottom core is placed on the upper surface of the hot-melt base 3 in a fitting manner, and then the embedding material is placed on the surface of the bottom core through the feeding groove 6. Then, the linkage mechanism is used to make the pressing cap 8 move towards the feeding groove 6. As the pressing cap 8 presses on the top of the feeding groove 6, the two supporting plates 4 move away from each other on both sides.

[0036] When taking out after the hot-melt processing of the bottom core and the embedding material is completed, the linkage mechanism is used again to move the pressing cap 8 away from the top of the feeding groove 6, and at the same time, the two supporting plates 4 move relatively towards the feeding groove 6. At this time, the displacement component is used to drive the heating sleeve 18 to drive the hot-melted bottom core to move out of the feeding groove 6 through the hot-melt base 3 on the top. As the two supporting plates 4 move relatively, they move to both sides of the hot-melt base 3 and are in the same plane as the top of the hot-melt base 3.

[0037] After adjusting the position of the hot-melt base 3 again, the hot-melt base 3 is retracted into the feeding groove 6. As the hot-melt base 3 moves, the bottom core on the surface of the hot-melt base 3 remains on the two pallets 4. This avoids direct contact after the sample preparation is completed and prevents burns caused by direct picking, thus ensuring the safety of the sampling process.

[0038] Among them, the linkage mechanism includes a cylinder 9 arranged on the top of the pressing cap 8. One end of two mutually parallel support columns 12 is fixedly installed vertically on both sides of the top of the processing table 2, and the other ends of the two support columns 12 are vertically and fixedly installed parallel to each other on the lower surface of the top plate 10. The top plate 10 is fixed above the processing table 2 through the two support columns 12. The cylinder barrel end of the cylinder 9 is fixed inside the top plate 10, and the movable end of the cylinder 9 is vertically fixed on the top of the pressing cap 8.

[0039] One end of a transmission rod 5 is symmetrically and rotatably arranged on both sides of the outer wall of the pressing cap 8. On both sides of the outer wall of the pressing cap 8, first fixing frames 37 are symmetrically and fixedly installed. Bearings are embedded in the opposite inner walls of the two first fixing frames 37. Both ends of a first central shaft 38 are respectively embedded in the two bearings. One end of the transmission rod 5 is sleeved outside the first central shaft 38 through a first connecting piece 39 installed. On the surfaces of the two moving seats 14 opposite to the pressing cap 8, second fixing frames 34 are fixedly installed. Bearings are embedded in the opposite inner walls of the second fixing frames 34. Both ends of a second central shaft 36 are respectively embedded in the two bearings. The other end of the transmission rod 5 is sleeved outside the first central shaft 38 through a second connecting piece 35 installed, so that both ends of the transmission rod 5 are hinged to the pressing cap 8 and the moving seat 14 respectively.

[0040] The other end of the transmission rod 5 is rotatably provided with a moving seat 14, and the pallet 4 is fixedly installed on the side wall of the moving seat 14 opposite to the pressing cap 8. The moving seat 14 is slidably arranged on the top of the support seat 7, and a guiding component is arranged between the support seat 7 and the moving seat 14. Through the guiding component between the moving seat 14 and the support seat 7, the moving seat 14 fits and moves on the upper surface of the support seat 7, and the direction deviation of the moving seat 14 is prevented through the guiding component.

[0041] During sample preparation, the hot-melt base 3 is adjusted to the corresponding position of the feeding groove 6 through the displacement component. Then, the bottom core is placed on the surface of the hot-melt base 3 in a fitting manner, and then the embedded material is placed inside the feeding groove 6 and pressed on the bottom core. Then, the solenoid valve of the air duct connected to the inside of the cylinder 9 is opened, so that the movable end of the cylinder 9 drives the pressing cap 8 to move towards the feeding groove 6, and at the same time, the two pallets 4 linked move towards both sides, so that the inner wall of the pressing cap 8 presses on the top of the embedded material, and the embedded material is pressed on the bottom core. Then, the bottom core is melted by the heater 30 inside the heating sleeve 18, so that the bottom core is embedded at the bottom of the embedded material.

[0042] After that, the movable end of the cylinder 9 drives the compression cap 8 to move again, so that the compression cap 8 moves away from the feeding groove 6. During this process, one end of the transmission rod 5 hinged on both sides of the compression cap 8 is driven to move, so that the two moving seats 14 hinged at the other ends of the two transmission rods 5 drive the two supporting plates 4 to move relatively. At the same time, the displacement assembly moves the embedded material on the hot-melt base 3 to the outside of the feeding groove 6. Then continue to adjust the position of the compression cap 8 so that the two supporting plates 4 on both sides fit symmetrically on the outer walls of both sides of the heating sleeve 18. After that, the displacement assembly makes the heating sleeve 18 drive the hot-melt base 3 to retract into the inside of the feeding groove 6, and at the same time, the embedded material remains on the upper surfaces of the two supporting plates 4 and waits to be taken after cooling, making the process of taking materials safer, avoiding damage caused by too high temperature of the sample, and thus bringing convenience to the operation process of relevant personnel.

[0043] It should be noted that the guiding assembly includes a guiding rod 29 embedded and installed in the inner cavity of the supporting seat 7, and the supporting seat 7 is fixedly installed on the top of the processing table 2. The two supporting seats 7 are symmetrically fixed on both sides of the feeding groove 6, and the supporting seat 7 fits on the upper surface of the processing table 2. A groove 28 is longitudinally opened on the contact surface between the supporting seat 7 and the moving seat 14, and both ends of the guiding rod 29 are vertically fixed on the inner walls on both sides of the groove 28. A guiding seat 40 is arranged at the bottom of the moving seat 14, and the guiding seat 40 is sleeved outside the guiding rod 29. One end of the connecting rod 41 is vertically fixed at the bottom of the moving seat 14, and the other end of the connecting rod 41 is fixed at the top of the guiding seat 40. The guiding seat 40 is movably sleeved outside the guiding rod 29 through a mounting hole opened on the surface and penetrating the inner cavity.

[0044] During the process of adjusting the positions of the two supporting plates 4, when the moving seat 14 is driven to move by the transmission rod 5, the moving seat 14 drives the guiding seat 40 to slide on the outer wall of the guiding rod 29. Through the sliding cooperation between the guiding seat 40 and the guiding rod 29, the stability of the moving direction of the moving seat 14 is ensured, and further the accuracy of the bottom supporting position of the sample-making bottom core is ensured.

[0045] In addition, the displacement assembly includes a first movable shaft 21 rotatably arranged in the inner cavity of the base 1. A second movable shaft 20 is rotatably arranged in the inner cavity of the base 1, and the second movable shaft 20 is relatively perpendicular to the first movable shaft 21. Two mutually parallel horizontal first support rods 24 are vertically fixedly installed in the inner cavity of the base 1. The other ends of the two first support rods 24 are both fixedly installed with first bearing seats 23. The first movable shaft 21 is simultaneously embedded in the two first bearing seats 23, and both ends of the first support rod 24 extend outside the first bearing seats 23. So that the first movable shaft 21 rotates in a position parallel to the horizontal plane inside the base 1.

[0046] Two longitudinal second support rods 32 are fixedly installed in parallel in the inner cavity of the base 1. The other ends of the two second support rods 32 are fixedly installed with second bearing seats 22. The second movable shaft 20 is longitudinally embedded in the interiors of the two second bearing seats 22, and both ends of the second movable shaft 20 extend outside the second bearing seats 22. Thus, the second movable shaft 20 and the first movable shaft 21 are in a relatively perpendicular position.

[0047] The outer wall of the first movable shaft 21 near the top is threadedly connected to the heating sleeve 18. The heating sleeve 18 sequentially penetrates through the top of the base 1 and the bottom of the processing table 2 and extends into the inner cavity. The first movable shaft 21 drives the second movable shaft 20 to rotate through a transmission mechanism. The top of the heating sleeve 18 sequentially penetrates through the top of the base 1 and the bottom of the processing table 2 and extends into the inner cavity of the processing table 2. An external thread 19 of a certain length is provided on the outer wall at the top of the first movable shaft 21. An internal thread 33 corresponding to the depth of the external thread 19 is provided on the bottom surface of the heating sleeve 18. The first movable shaft 21 and the heating sleeve 18 are threadedly connected through the internal thread 33 and the external thread 19.

[0048] The transmission mechanism includes a first bevel gear 16 sleeved on the outer wall of the first movable shaft 21. A second bevel gear 17 is sleeved on the outer wall of the second movable shaft 20 near the bottom, and the second bevel gear 17 meshes with the first bevel gear 16. A positioning component for preventing the heating sleeve 18 from shifting in position is provided in the inner cavity of the processing table 2. The first bevel gear 16 is longitudinally fixedly sleeved on the outside of the first movable shaft 21 through a mounting hole provided in the center. The second bevel gear 17 is horizontally fixedly sleeved on the outside of the second movable shaft 20 through a mounting hole provided in the center. The first movable shaft 21 penetrates through the side wall of the base 1 and extends to the outside. An operating wheel 15 is fixedly installed at the end of the first movable shaft 21 extending outside the base 1. The first movable shaft 21 is driven to rotate by rotating the operating wheel 15.

[0049] When adjusting the position of the hot melting base 3, rotate the operating wheel 15, so that the operating wheel 15 drives the first movable shaft 21 to rotate, so that the first movable shaft 21 drives the first bevel gear 16 on its outer surface to rotate, so that the second bevel gear 17 meshing with the first bevel gear 16 drives the second movable shaft 20 to rotate. The heating sleeve 18 threadedly connected to the second movable shaft 20 moves in the vertical direction, thereby adjusting the position of the hot melting base 3. Adjust according to the sampling position, which brings convenience to the operation process of relevant personnel.

[0050] In addition, the orientation component includes a movable frame 25 sleeved outside the heating sleeve 18, and a sleeve rod 26 is fixedly installed at the bottom of the movable frame 25. A stabilizing rod 27 is fixedly installed at the bottom inner wall of the processing table 2, and the sleeve rod 26 is sleeved outside the stabilizing rod 27. The movable frame 25 is fixedly sleeved outside the heating sleeve 18 through a mounting through hole opened at the central position, so that the heating sleeve 18 drives the movable frame 25 to move. The shape of the movable frame 25 corresponds to the inside of the processing table 2, so that the movable frame 25 fits and slides on the inner wall of the processing table 2. The top end of the sleeve rod 26 is fixedly installed vertically at the bottom of the movable frame 25. The stabilizing rod 27 is fixedly installed vertically at the bottom inner wall of the processing table 2, and the bottom end of the sleeve rod 26 is movably sleeved outside the stabilizing rod 27 through a mounting hole opened, so that the sleeve rod 26 fits and slides on the outer wall of the stabilizing rod 27.

[0051] During the process of adjusting the position of the heating sleeve 18 by rotating the second movable shaft 20, the heating sleeve 18 drives the sleeve rod 26 to fit and slide on the outer wall of the stabilizing rod 27 through the movable frame 25. The sleeve rod 26 parallel to the heating sleeve 18 ensures the stability of the moving direction of the heating sleeve 18 and avoids position deviation, thereby ensuring the stability of the moving direction of the hot-melt base 3.

[0052] Furthermore, a slot 13 is circumferentially opened at the top of the material feeding groove 6, and a positioning plug 11 corresponding to the slot 13 is circumferentially arranged at the bottom of the pressing cap 8. During the process of adjusting the position of the pressing cap 8, the positioning plug 11 and the slot 13 are inserted and matched to prevent the position deviation of the pressing cap 8, thereby ensuring the tightness of the fit between the pressing cap 8 and the top of the inserted material, and further ensuring the stability of the bottom core inlay.

[0053] The support plate 4 is an arc-shaped plate, and the radian of the support plate 4 corresponds to that of the heating sleeve 18, ensuring the degree of fit between the support plate 4 and the outer wall of the heating sleeve 18.

[0054] The hot-melt base 3 is a heat conductor, and the heat-conducting material of the hot-melt base 3 ensures the heat conduction during the bottom core inlay process.

[0055] The working principle of the bottom core inlay machine of an electron microscope in this embodiment is as follows: When making a sample for an electron microscope, rotate the operating wheel 15, so that the operating wheel 15 drives the first movable shaft 21 to rotate. The first movable shaft 21 drives the first bevel gear 16 on its outer surface to rotate, so that the second bevel gear 17 meshing with the first bevel gear 16 drives the second movable shaft 20 to rotate. The heating sleeve 18 threadedly connected to the second movable shaft 20 moves in the vertical direction, and the hot-melt base 3 is adjusted to a suitable material feeding position.

[0056] Then, place the bottom core fittingly on the upper surface of the hot-melt base 3. Open the solenoid valve of the air cylinder 9 connected to the inside of the air cylinder, so that the movable end of the air cylinder 9 drives the pressure cap 8 to move towards the material discharge groove 6. At the same time, the two linked support plates 4 move towards both sides, so that the inner wall of the pressure cap 8 presses against the top of the inserted material, and the inserted material is pressed onto the bottom core. Then, heat the bottom core by the heater 30 inside the heating sleeve 18 to melt the bottom core, so that the bottom core is embedded at the bottom of the inserted material.

[0057] After that, drive the pressure cap 8 to move again through the movable end of the air cylinder 9, so that the pressure cap 8 moves away from the material discharge groove 6. During this process, drive one end of the transmission rod 5 hinged on both sides by the pressure cap 8 to move, so that the other ends of the two transmission rods 5 hinged to the two movable seats 14 drive the two support plates 4 to move relatively. At the same time, move the inserted material on the hot-melt base 3 to the outside of the material discharge groove 6 by rotating the operation wheel 15. Then continue to adjust the position of the pressure cap 8 so that the two support plates 4 on both sides fit symmetrically on the outer walls of both sides of the heating sleeve 18. After that, drive the heating sleeve 18 to drive the hot-melt base 3 to retract into the material discharge groove 6 by rotating the operation wheel 15. At the same time, the inserted material melted with the bottom core remains on the upper surfaces of the two support plates 4 and waits to be taken after cooling.
