Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Example 1

[0033] like Figures 1-5 As shown, a roller-based glass slide transport device includes a mounting base plate 1, a glass slide box 2, a glass slide 3, a connecting rod structure 4, a slider fixing block 5, a linear guide rail 6, an idler wheel 7, a synchronous wheel 8, a synchronous belt 9, and a drive motor 10.

[0034] The connecting rod structure 4 includes: a support shaft 41, a first bushing 42, a bearing 43, an L-shaped connecting rod 44, a roller fixing shaft 45, a roller bearing 46, a rolling roller 47, a first locking screw 48, a connecting rod 49, a second bushing 4a, and a second locking screw 4b.

[0035] The L-shaped connecting rod 44 includes a first connecting rod 441 and a second connecting rod 442, a roller fixing shaft mounting hole 443 connected to the front end of the first connecting rod 441, a support shaft mounting hole 444 connected at the junction of the first connecting rod 441 and the second connecting rod 442, and a plug screw mounting hole 445 connected to the end of the second connecting rod 442. The bearing 43 is threaded in the support shaft mounting hole 444, the roller fixing shaft 45 passes through the roller fixing shaft mounting hole 443, and the first plug screw 48 passes through the plug screw mounting hole 445.

[0036] Linear guide rail 6 is fixed to mounting base plate 1 with screws. Then, slider fixing block 5 is fixed to linear guide rail 6. Second locking screw 4b is passed through connecting rod 49 and fixed to slider fixing block 5 with second bushing 4a. Then, support shaft 41 is fixed to mounting base plate 1. Next, L-shaped connecting rod 44 is passed through bearing 43 and fixed to support shaft 41 with screws. One end of L-shaped connecting rod 44 is fixed to one end of connecting rod 49 with first locking screw 48 passing through first bushing 42. The other end of L-shaped connecting rod 44 is fixed to roller fixing shaft 45 below the connecting rod with screws. Roller bearing 46 is fixed to inside rolling roller 47 with snap ring. Then, rolling roller 47 is fixed to the other end of roller fixing shaft 45 with screws. In this way, one set of structure is installed at each of the left and right ends of slide box 2. An idler wheel 7 is installed on the support shaft 41 of one set of structure with snap ring. Synchronous belt 9 is sleeved between idler wheel 7 and synchronous wheel 8. Synchronous wheel 8 is fixed to the shaft of drive motor 10 with set screw.

[0037] This mechanism mainly uses other power mechanisms to drive the slider fixing block 5 to move back and forth on the linear guide rail 14. The opening and closing of the two rolling rollers 47 are achieved through a linkage structure. The L-shaped linkage 44 has a strip-shaped mounting hole 443 (as shown below). Figure 3 The roller 47 is brought into close contact with the synchronous belt 9 on the idler wheel 7, and the drive motor 10 drives the synchronous belt 9 to rotate. The roller 47 rotates freely through friction with the synchronous belt 9, thus easily extruding the slide 3. Ten slides 3 can be installed in the slide box 2 at the same time. The slide box 2 moves up and down through other lifting mechanisms. When the slide box 2 rises to the first slide 3 reaching the designated position, the two rollers 2 close through the linkage structure 4 to clamp the first slide 3. At this time, the drive motor 10 is started to drive the synchronous belt 9 and rollers 2 to rotate and transport the slide 3 to the designated position. When the slide 3 has finished working, the two rollers 47 open through the linkage mechanism 4, and the slide 3 is pushed back to the slide box 2 through other power mechanisms. At this time, the slide box 2 is moved up to the second slide 3 reaching the designated position. The above steps are repeated to complete the sweeping of all slides 3 on the slide box 2.

[0038] The surface of the rolling roller 47 is treated with two knurled straight lines (such as...). Figure 4 As shown, one area features knurled straight lines on the upper and lower outer edges, primarily to increase friction with the timing belt and effectively prevent slippage of the rolling roller 47; the other area features knurled straight lines on the concave part of the rolling roller 47, mainly to increase friction between the rolling roller 47 and the slide 3, effectively facilitating the smooth extrusion of the slide 3. The slide box 2 adopts a design with a partially cut-off front end (as shown below). Figure 5 This design is specifically tailored to complement the extrusion structure of the rolling roller 47. In summary, this design is simple in structure, easy to operate and maintain, and suitable for the field of automated testing of medical devices.

[0039] The L-shaped connecting rod 44 that fixes the rolling roller 47 adopts a strip-shaped mounting hole (such as... Figure 3 As shown, the contact tightness of the synchronous belt on the roller and the idler wheel can be easily adjusted. At the same time, the roller fixing shaft 45 rotates with the support shaft 1 of the fixed idler wheel 7 as the center. This ensures that when the rolling roller 47 opens and closes, the synchronous belt 9 on the rolling roller 47 and the idler wheel 7 are always in contact and friction, ensuring the smooth extrusion of the glass slide 3. This greatly simplifies the structure of the entire system and reduces production costs and maintenance difficulty.

[0040] Slide box 2 adopts a design with a portion cut off at the front end (e.g.) Figure 5 As shown, it is a unique design mainly to complement the extrusion structure of the rolling roller 47.

[0041] In this embodiment, the mounting base plate 1 has a length, width, and height of 142*91*8mm and is made of 6061 aluminum alloy. The angle of the L-shaped connecting rod 44 is 110°. The outer diameter of the bearing 43 is 7mm, the inner diameter is 4mm, and the height is 2.5mm. The synchronous pulley 8 is of model MXL-20 teeth with an inner diameter of 5mm, and the idler pulley 7 is of model MXL-20 teeth with an inner diameter of 4mm.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
