Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0019] This application provides a method for testing the service life of a slider in a pathological sectioning machine, specifically the slider in the vertical drive structure of the sample feeding mechanism of the pathological sectioning machine. The method for testing the service life of the slider includes the following steps: The drive unit of the pathology microtome drives the slider at a preset rotation speed M revolutions per minute for a preset time T. A sectioning experiment is performed using a pathology microtome equipped with the drive unit. The quality of the sections obtained from the sectioning experiment is determined to meet the preset requirements. If the section quality does not meet the preset requirements, the lifespan K of the slider is determined based on the preset time T. If the section quality meets the preset requirements, the drive unit of the pathology microtome continues to drive the slider at the preset rotation speed M revolutions per minute for the preset time T, and the above steps are repeated until the section quality does not meet the preset requirements. The lifespan K of the slider is determined based on the preset time T and the number of times the drive unit drives the slider at the preset rotation speed M revolutions per minute for the preset time T, N.
[0020] In this first instance, the weight and dimensions of the slide were measured and recorded before the drive unit of the pathology slicer was driven at a preset rotation speed M revolutions per minute for a preset time T.
[0021] After each sectioning experiment using a pathology microtome equipped with a drive unit, the weight and dimensions of the slider were measured and recorded, and the degree of wear on the slider was determined.
[0022] The lifespan K of the slider is determined based on a preset time T, specifically by determining the lifespan K of the slider based on the degree of wear and the preset time T. Further, in determining the lifespan K of the slider based on the degree of wear and the preset time T, the lifespan K of the slider is first determined as K < T, and then the lifespan K of the slider is determined as K < T1 based on the degree of wear, where T1 ≤ T. In other words, the range for determining the lifespan K of the slider is narrowed down based on the degree of wear.
[0023] The lifespan K of the slider is determined based on a preset time T and the number of times the drive unit rotates at a preset speed M revolutions per minute (N). Specifically, the lifespan K of the slider is determined based on the degree of wear, the preset time T, and the number of times the drive unit rotates at a preset speed M revolutions per minute (N). Further, in determining the lifespan K of the slider based on the degree of wear, the preset time T, and the number of times the drive unit rotates at a preset speed M revolutions per minute (N), the lifespan K of the slider is first determined as: (N-1)T < K < NT. Then, based on the degree of wear, the lifespan K of the slider is determined as: (N-1)T2 < K < NT3, where T2 > T and T3 < T. In other words, the range of the lifespan K of the slider is narrowed down based on the degree of wear.
[0024] See Figure 1-2 The vertical drive structure includes a slider 114, a guide rail 115, a drive shaft 118, and a drive unit.
[0025] The slider 114 is mounted on a vertical slide in the sample feeding mechanism of the pathology slideer, which can slide vertically and is used for mounting the sample connecting seat. Specifically, the slider 114 is mounted on an adjusting seat detachably mounted on the vertical slide in the sample feeding mechanism of the pathology slideer. Moreover, the slider 114 can slide laterally.
[0026] There are two guide rails 115. Both guide rails 115 are mounted on the adjusting seat. Both guide rails 115 are arranged laterally and longitudinally. Under the above conditions, the slider 114 is disposed between the two guide rails 115, so that the slider 114 is mounted on the adjusting seat and can slide laterally.
[0027] The drive shaft 118 is connected to the slider 114. Moreover, the centerline of the drive shaft 118 extends longitudinally.
[0028] The drive unit is connected to the drive shaft 118. Furthermore, the drive unit can rotate about a longitudinal line that is parallel to the center line of the drive shaft 118.
[0029] The drive shaft 118 is connected to the slider 114 or the drive unit via the bearing 119, so that the rotating drive unit drives the slider 114 to slide laterally via the drive shaft 118, and drives the slider 114, the adjusting seat and the vertical slide to slide vertically, and reduces the friction between the drive shaft 118 and the slider 114 or the drive unit via the bearing 119.
[0030] Furthermore, the outer ring of the bearing 119 is fixedly mounted on the slider 114 or the drive unit. Specifically, the slider 114 or the drive unit has a mounting groove, the center line of which extends longitudinally, and the bearing 119 is fixedly mounted in the mounting groove. The first end of the drive shaft 118 on its center line is inserted into the inner ring of the bearing 119. Moreover, the first end of the drive shaft 118 is fixedly connected to the inner ring. Specifically, the first end of the drive shaft 118 is fixedly connected to the inner ring via a pin. The above arrangement allows the first end of the drive shaft 118 to be connected to the slider 114 or the drive unit via the bearing 119.
[0031] The drive unit or slider 114 has a mounting hole with its centerline extending longitudinally. A second end of the drive shaft 118 along its centerline is inserted into the mounting hole. Furthermore, the second end of the drive shaft 118 is fixedly connected to the drive unit. Specifically, the second end of the drive shaft 118 is fixedly connected to the drive unit via adhesive. This arrangement ensures that the second end of the drive shaft 118 is fixedly connected to the drive unit or slider 114.
[0032] Optionally, the outer ring of the bearing 119 is fixedly mounted on the slider 114, and the first end of the drive shaft 118 on its center line is inserted into the inner ring of the bearing 119 and fixedly connected to the inner ring. Furthermore, the drive unit has a mounting hole, and the second end of the drive shaft 118 on its center line is inserted into the mounting hole and fixedly connected to the drive unit. Alternatively, the outer ring of the bearing 119 is fixedly mounted on the drive unit, and the first end of the drive shaft 118 on its center line is inserted into the inner ring of the bearing 119 and fixedly connected to the inner ring. Furthermore, the slider 114 has a mounting hole, and the second end of the drive shaft 118 on its center line is inserted into the mounting hole and fixedly connected to the slider 114.
[0033] The drive unit includes a bracket 120, a support bearing 121, a handwheel shaft 122, a handle (not shown in the figure), a gear disk 123, a locking rod 124, and a locking buckle 125.
[0034] The support 120 defines a receiving cavity 1201, which is arranged in a flat, longitudinal shape. Both sides of the receiving cavity 1201 have circular openings 1202, namely a first circular opening 1205 and a second circular opening 1206. Both sides of the receiving cavity 1201 have strip-shaped openings 1203 in the transverse direction. The lower side of the receiving cavity 1201 has a communicating opening 1204. The four corners of the lower part of the support 120 are respectively bolted to the base 101 of the sample feeding mechanism of the pathology slide machine.
[0035] There are two support bearings 121, namely a first support bearing 1211 and a second support bearing 1212. The center lines of both the first support bearing 1211 and the second support bearing 1212 extend longitudinally. The first support bearing 1211 and the second support bearing 1212 are respectively fixed in the first circular opening 1205 and the second circular opening 1206 of the bracket 120.
[0036] The handwheel shaft 122 includes a shaft body 1221 and a disc body 1222. The shaft body 1221 is a columnar shape with its center line extending longitudinally, and any cross-section of it is circular. The disc body 1222 is a circular plate with its center line extending longitudinally. The disc body 1222 is fixed to one end of the shaft body 1221, and is perpendicular to the shaft body 1221. The center line of the disc body 1222 coincides with the center line of the shaft body 1221. The shaft body 1221 passes through two support bearings 121 on the bracket 120. The handwheel shaft 122 is rotatable about a horizontal line extending longitudinally. The disc body 1222 is connected to the drive shaft 118.
[0037] Under the above conditions, the drive unit of the pathology slicer drives the slider at a preset rotation speed M revolutions / minute for a preset time T. Specifically, the handwheel shaft rotates at a preset rotation speed M revolutions / minute for a preset time T.
[0038] The handle is fixed to the free end of the shaft 1221 of the handwheel shaft 122. The handle drives the handwheel shaft 122 to rotate about a horizontal line extending longitudinally.
[0039] The centerline of the gear disk 123 extends longitudinally. The gear disk 123 is disposed in the receiving cavity 1201 of the bracket 120 through the strip-shaped opening 1203. The gear disk 123 is fixed to the middle of the shaft body 1221 of the handwheel shaft 122. The gear disk 123 rotates with the handwheel shaft 122 about the horizontal line extending longitudinally.
[0040] The locking rod 124 is vertically positioned. The lower end of the locking rod 124 is inserted into the first mounting hole 1011 of the base, and the upper end of the locking rod 124 passes through the communicating opening 1204 of the bracket 120, and is positioned opposite to the gear disc 123. The upper end of the locking rod 124 is wedge-shaped. The lower end of the locking rod 124 has a insertion hole 1241, the centerline of which extends longitudinally.
[0041] When the locking rod 124 moves to the first position, it engages with the gear disk 123, locking the gear disk 123. When it moves to the second position, it disengages from the gear disk 123, unlocking the gear disk 123. The locking rod 124 can move elastically in the vertical direction. Under the action of external force, the locking rod 124 moves downward to the second position, and after the external force is removed, it moves upward to the first position. A spring is sleeved on the outside of the locking rod 124. The lower end of the spring abuts against the bracket 120, and the upper end of the spring abuts against the retaining ring 126 set on the locking rod 124, allowing the locking rod 124 to move elastically in the vertical direction. The retaining ring 126 is sleeved and fixed on the outside of the locking rod 124.
[0042] The locking buckle 125 includes a rod 1251 and a button 1252. The rod 1251 is a rod-shaped structure with its center line extending longitudinally, and any cross-section of it is circular. The button 1252 is a circular plate-shaped structure with its center line extending longitudinally. The button 1252 is fixed to one end of the rod 1251, and is perpendicular to the rod 1251. The center line of the button 1252 coincides with the center line of the rod 1251. The free end of the rod 1251 is inserted into the second mounting hole 1012 of the base 101, and the button 1252 is located on one side of the base 101 in the longitudinal direction.
[0043] The insert rod 1251 can be inserted into the socket 1241, so that the locking rod 124 is held in the second position. The insert rod 1251 has a first insert segment 1253, a second insert segment 1254 and a third insert segment 1255. The first insert segment 1253 is cylindrical. The second insert segment 1254 is located at the end of the first insert segment 1253 away from the button 1252. The second insert segment 1254 is tapered and gradually tapers away from the first insert segment 1253. As the second insert segment 1254 is inserted into the socket 1241, the locking rod 124 gradually moves downward to the second position. After the first insert segment 1253 begins to be inserted into the socket 1241, the locking rod 124 is held in the second position. The third insertion segment 1255 is located at the end of the second insertion segment 1254 away from the first insertion segment 1253. The third insertion segment 1255 is cylindrical, so that when the locking rod 124 is in the first position, the third insertion segment 1255 is still inserted in the insertion hole 1241, thus preventing the relative displacement of the locking rod 124 and the locking buckle 125.
[0044] See Figure 3-4 The pathology slicer sample feeding mechanism includes a base 101, a horizontal slide 102, a horizontal drive structure, a vertical slide 112, an adjustment seat 113, the aforementioned vertical drive structure, and a sample connection seat 116.

[0049] A detection element 110 is installed on the lead screw box 1021. A sensor 111 is installed on the base 101. The sensor 111 senses the detection element 110, so that the lateral sliding distance of the lead screw box 1021 can be obtained based on the sensing information of the sensor 111.
[0050] The guide rail fixing plate 1022 has a preset height in the vertical direction. The first side of the guide rail fixing plate 1022 in the horizontal direction is installed at one end of the screw box 1021 in the horizontal direction, and the vertical slide 112 is installed on the second side of the guide rail fixing plate 1022 in the horizontal direction.

[0058] The drive component 105 is mounted on the lead screw box 1021 and connected to the lead screw 103, causing the drive component 105 to drive the lead screw 103 to rotate around its own center line. The lead screw 103 and the lead screw box 1021 slide laterally relative to the lead screw nut 1031, the connecting block 104, and the base 101. The drive component 105 is a motor. The drive component 105 is mounted on the lead screw box 1021 via a drive component connecting box 109 and connected to the lead screw 103 via a coupling 108.
