Description

Technical Field

[0001] This utility model relates to the field of material transfer technology, specifically to a material transfer device for a smart laboratory. Background Technology

[0002] In electronic metrology laboratories, laboratory transport devices are specialized mechanisms used to move electronic measuring instruments from one location to another. The typical procedure involves manually moving the electronic measuring instrument onto the device's surface, then manually pushing or pulling it to allow the device to move using its casters, thus completing the transport of the electronic measuring instrument.

[0003] However, current laboratory transport equipment still has significant drawbacks in practical use. Specifically, the equipment often encounters uneven surfaces when transporting electronic measuring instruments. Due to the large size of the instruments, they are prone to bumping and jolting on uneven surfaces. Existing laboratory transport equipment lacks a clamping structure to stably hold the electronic measuring instruments during transport. To prevent displacement or tipping during bumps, multiple workers must simultaneously apply force to secure the instruments before transport can continue. This not only significantly reduces work efficiency but also is time-consuming and labor-intensive, negatively impacting the efficient operation of daily laboratory tasks.

[0004] Therefore, in view of the above-mentioned problems existing in the transport of electronic measuring instruments by existing laboratory material transfer devices, it is urgent to propose a new technical solution to solve them. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the aforementioned background technology and provide a smart laboratory material transfer device that can solve the problems of existing transfer devices being unable to stably clamp electronic measuring instruments during transportation, and requiring multiple people to cooperate during transportation, which is time-consuming and labor-intensive.

[0006] To achieve this objective, the intelligent laboratory material transfer device designed in this utility model includes a movable base, a fixed block set on the base, a moving block, a first lead screw and nut mechanism, a second lead screw and nut mechanism, a third lead screw and nut mechanism, a fourth lead screw and nut mechanism, a transmission block, a clamping plate mechanism, a transmission rod, and a power mechanism.

[0034] like Figure 1As shown in Figure 3, the intelligent laboratory material transfer device designed in this utility model includes a movable base 1, a fixed block 2 set on the base 1, a moving block 3, a first lead screw and nut mechanism 4, a second lead screw and nut mechanism 5, a third lead screw and nut mechanism 10, a fourth lead screw and nut mechanism 11, a transmission block 6, a clamping plate mechanism 7, a transmission rod 8, and a power mechanism 9.

[0035] The fixed block 2 is fixedly mounted on the base 1, and the movable block 3 is slidably mounted on the base 1. A power mechanism 9 is located between the movable block 3 and the fixed block 2, and is used to push the movable block 3 to move back and forth relative to the fixed block 2. A movable groove 16 is provided on the base 1, allowing the movable block 3 to move along the groove 16 under the action of the power mechanism 9. A rubber pad 14 is provided on the base 1 to prevent items from moving; clamped items can be placed on the rubber pad 14. A handle 12 for pushing the entire transfer device is fixed on the side of the base 1 away from the clamping mechanism 7. Multiple rollers 13 are provided at the bottom of the base 1 to facilitate the movement of the entire transfer device. A connecting block 15 is also provided on one side of the base 1, and the handle 12 is hinged to the connecting block 15. A rubber sleeve is provided in the middle of the handle 12; the rubber sleeve increases the friction between the hand and the push / pull rod when manually pushing and pulling the transfer device, thus reducing effort during pushing and pulling. The power mechanism 9 can be an electric telescopic rod, including a cylinder 91 and a telescopic rod 92. The cylinder 91 is fixedly installed inside the fixed block 2, and the end of the telescopic rod 92 is fixedly installed on the moving block 3.

[0036] There are three clamping mechanisms 7. Two clamping mechanisms 7 are used to clamp the left and right sides of the item, and one clamping mechanism 7 presses the top of the item. Together with the base 1, they form an upper and lower positioning and clamping structure for the item, thereby positioning, supporting and clamping the item on the base 1.

[0037] like Figure 9 As shown in Figure 10, the clamping mechanism 7 includes multiple spring telescopic sleeves 71 for elastically clamping items and preventing hard contact between the clamping mechanism 7 and the clamped items, as well as a first clamping plate 72 and a second clamping plate 73 arranged parallel to each other. The multiple spring telescopic sleeves 71 are fixedly connected between the first clamping plate 72 and the second clamping plate 73. Each spring telescopic sleeve 71 includes a spring 711 and a telescopic sleeve 712 coaxially arranged inside the spring 711. The first clamping plate 72 is provided with multiple grooves 721 for placing the spring 711 and the telescopic sleeve 712. The two ends of the telescopic sleeve 712 are fixedly connected to the first clamping plate 72 and the second clamping plate 73, respectively. The upper and lower ends of the spring 711 are fixedly connected to the first clamping plate 72 and the second clamping plate 73, respectively.

[0038] A first rotating rod 74 is fixed inside one side of the first clamping plate 72. The first clamping plate 72 is hinged to the first adjusting block 41 or the third adjusting block 101 via the first rotating rod 74. Specifically, the hinged connection structure between the clamping plate mechanism 7 and the first adjusting block 41 and the third adjusting block 101 is as follows:

[0039] like Figure 1 As shown, a first lead screw and nut mechanism 4 is provided on the left and right sides of the fixed block 2, and a third lead screw and nut mechanism 10 is provided in the middle of the fixed block 2.

[0040] Among them, such as Figure 6 and Figure 8 As shown, the first lead screw and nut mechanism 4 includes a first adjusting block 41 that can move horizontally left and right relative to the fixed block 2 and a first lead screw 42 arranged in the left and right direction of the fixed block 2. A first lead screw groove 21 for accommodating the first lead screw 42 is opened on the left and right sides of the fixed block 2, respectively. One end of the first lead screw 42 is rotatably disposed in the first lead screw groove 21, and the other end extends out of the first lead screw groove 21 and is fixedly connected to a first adjusting handle 421. By rotating the first adjusting handle 421, the first adjusting block 41 can be moved on the first lead screw 42 in the left and right direction of the fixed block 2. A first opening 411 for the first rotating rod 74 to pass through and a second opening 412 for the first lead screw 42 to pass through are opened on the first adjusting block 41. The first opening 411 and the second opening 412 are arranged perpendicular to each other. The first lead screw and nut mechanism 4 also includes a first limiting plate 43 fixedly disposed on the left or right side of the fixed block 2 to prevent the first adjusting block 41 from falling out of the first lead screw groove 21. A lead screw through hole that cooperates with the first lead screw 42 is opened in the first limiting plate 43.

[0041] like Figure 4 As shown, the third lead screw and nut mechanism 10 includes a third adjusting block 101 that can move vertically up and down relative to the fixed block 2, and a third lead screw 102 arranged along the vertical direction of the fixed block 2. A second lead screw groove 22 for accommodating the third lead screw 102 is provided in the middle of the fixed block 2. One end of the third lead screw 102 is rotatably disposed within the second lead screw groove 22, and the other end extends out of the second lead screw groove 22 and is fixedly connected to a second adjusting handle 1021. By rotating the second adjusting handle 1021, the third adjusting block 101 can move along the vertical direction of the fixed block 2 on the third lead screw 102. A third opening 1011 is provided on the third adjusting block 101 for the first rotating rod 74 to pass through (e.g., ...). Figure 6 (as shown) and a fourth opening 1012 through which the third lead screw 102 passes. The third opening 1011 and the fourth opening 1012 are arranged perpendicular to each other. The third lead screw nut mechanism 10 also includes a second limiting plate 44 fixedly disposed on the top of the fixing block 2 to prevent the third adjusting block 101 from coming out of the third lead screw groove 22. A lead screw through hole that cooperates with the third lead screw 102 is opened in the second limiting plate 44.

[0042] Two clamping mechanisms 7 are respectively hinged to the first adjusting blocks 41 of the first lead screw and nut mechanism 4 located on the left and right sides of the fixed block 2 via their respective first rotating rods 74. The remaining clamping mechanism 7 is hinged to the third adjusting block 101 of the third lead screw and nut mechanism 10 located in the middle of the fixed block 2 via its own first rotating rod 74. The clamping mechanisms 7 located on the left and right sides of the fixed block 2 are arranged perpendicularly to the clamping mechanism 7 located in the middle of the fixed block.

[0043] like Figure 1 As shown in Figure 3, a second lead screw and nut mechanism 5 is provided on the left and right sides of the moving block 3, and a fourth lead screw and nut mechanism 11 is provided in the middle of the moving block 3.

[0044] like Figure 6 As shown, the second lead screw and nut mechanism 5 includes a second adjusting block 51 that can move horizontally left and right relative to the moving block 3, a U-shaped first locking block 52 fixed to the left or right side of the moving block 3, and a second lead screw 53 arranged along the left and right direction of the moving block 3 (e.g., ...). Figure 2 As shown, the moving block 3 has first notches 31 on its left and right sides, which together with the first locking block 52 form the arrangement groove structure of the second lead screw 53. One end of the second lead screw 53 is rotatably connected to the moving block 3 and located in the U-shaped groove of the first locking block 52. The other end passes through the U-shaped groove of the first locking block 52 and is fixedly connected to a third adjusting handle 531. The second lead screw 53 is threadedly connected to a second adjusting block 51. The inner surface of the U-shaped groove of the first locking block 52 is fixedly connected to the moving block 3. The inner surface of the U-shaped groove of the first locking block 52 forms a limiting surface for the second adjusting block 51, preventing the second adjusting block 52 from coming out of the U-shaped groove of the first locking block 52, and preventing the second adjusting block 51 from rotating synchronously with the second lead screw 53. The second adjusting block 51 is fixedly connected to a second rotating rod 511 that is hinged to the other end of the transmission rod 8.

[0045] like Figure 5 and Figure 7 As shown, the fourth lead screw and nut mechanism 11 includes a fourth adjusting block 111 that can move vertically up and down relative to the moving block 3, a U-shaped second locking block 112 fixed in the middle of the moving block 3, and a fourth lead screw 113 arranged along the vertical direction of the moving block 3 (as shown). Figure 2As shown, the moving block 3 has a second notch 32 in the middle, which together with the second locking block 112 forms the arrangement groove structure of the fourth lead screw 113. One end of the fourth lead screw 113 is rotatably connected to the moving block 3 and located in the U-shaped groove of the second locking block 112. The other end passes through the U-shaped groove of the second locking block 112 and is fixedly connected to the fourth adjusting handle 1131. The fourth lead screw 113 is threadedly connected to the fourth adjusting block 111. The inner surface of the U-shaped groove of the second locking block 112 is fixedly connected to the moving block 3. The inner surface of the U-shaped groove of the second locking block 112 forms the limiting surface of the fourth adjusting block 111, preventing the fourth adjusting block 112 from coming out of the U-shaped groove of the second locking block 112, and at the same time preventing the fourth adjusting block 112 and the fourth lead screw 113 from rotating synchronously. The fourth adjusting block 111 is fixed with a third rotating rod 1111 that is hinged to the other end of the transmission rod 8.

[0046] like Figure 1 As shown in Figure 2, each second adjusting block 31 and fourth adjusting block 111 is hinged to one end of two transmission rods 8, and the other end of each transmission rod 8 is hinged to a transmission block 6. Two transmission blocks 6 are fixed on each of the three clamping mechanisms 7. The two clamping mechanisms 7 located on the left and right sides of the fixed block 2 are respectively hinged to the second adjusting blocks 51 of the second lead screw nut mechanism 5 on the left and right sides of the moving block 3 through two transmission blocks 6 and two transmission rods 8. The clamping mechanism 7 located in the middle of the fixed block 2 is hinged to the fourth adjusting block 111 of the fourth lead screw nut mechanism 11 through two transmission blocks 6 and two transmission rods 8. Multiple strip-shaped clearance grooves 23 for the transmission rods 8 to pass through are provided on the left and right sides and top of the fixed block 2 along the moving direction of the moving block 3. Figure 3 As shown, the transmission block 6 includes two support blocks 61 that are fixedly mounted on the first clamping plate 72 and are parallel to each other, and a fourth rotating rod 62 that is fixedly connected between the two support blocks 61. One end of the transmission rod 8 is hinged to the fourth rotating rod 62.

[0047] In this invention, the first lead screw and nut mechanism 4, the second lead screw and nut mechanism 5, the third lead screw and nut mechanism 10, and the fourth lead screw and nut mechanism 11 all include a lead screw that rotates but does not move axially, and a nut (i.e., an adjusting block) threadedly connected to the lead screw. In order to make the lead screw rotate but not move axially, so that the adjusting block threadedly connected to it can move along the lead screw, in addition to restricting the rotation of the adjusting block through the lead screw groove and the U-shaped groove of the locking block, the lead screw is also structurally designed as follows. Taking the second lead screw and nut mechanism 5 as an example, the structures of the other lead screw and nut mechanisms are the same or similar:

[0048] To ensure that the second lead screw 53 only rotates and does not move axially, the end of the second lead screw 53 connected to the moving block 3 can adopt one of the following common structures:

[0049] The deep groove ball bearing with shoulder structure consists of the following: A shoulder is machined at the end of the second lead screw 53 near the moving block 3. The deep groove ball bearing is installed in the corresponding hole of the moving block 3, with the shoulder of the lead screw mating with the inner ring of the deep groove ball bearing. The deep groove ball bearing can withstand both a certain radial load and a small axial load. The shoulder restricts the axial movement of the second lead screw 53 away from the support, while the outer ring of the deep groove ball bearing is fixed to the moving block 3, preventing the second lead screw 53 from moving axially into the moving block 3. This restricts the axial displacement of the second lead screw 53, allowing it to rotate only. When the third adjusting handle 531 is rotated, the second lead screw 53 rotates, and the second adjusting block 51 moves axially along the second lead screw 53.

[0050] The thrust ball bearing with a shoulder structure consists of the following: a shoulder is machined at the end of the second lead screw 53 near the moving block 3, and a suitable mounting hole is made on the moving block 3 to install the thrust ball bearing. One race of the thrust ball bearing mates with the lead screw shoulder, and the other race is fixed to the moving block 3. The thrust ball bearing is specifically designed to bear axial loads, and the shoulder, in conjunction with the thrust ball bearing, effectively restricts the axial movement of the lead screw. When the second lead screw 53 is subjected to axial force, the force is transmitted to the rolling elements (balls) through the race connected to the second lead screw 53, and then to the race fixed to the moving block 3. Since the moving block 3 remains stationary, this restricts the axial displacement of the second lead screw 53, ensuring that the second lead screw 53 can only rotate.

[0051] The angular contact ball bearing structure consists of an angular contact ball bearing installed within the movable block 3, with one end of the second lead screw 53 directly mating with the inner ring of the bearing. The angular contact ball bearing can simultaneously withstand radial and axial loads. By appropriately selecting the contact angle and installation method (e.g., back-to-back, face-to-face, or tandem installation) of the angular contact ball bearing, it can effectively withstand the axial force generated by the second lead screw 53 during rotation, restricting its axial movement and limiting it to rotation only. For example, using back-to-back angular contact ball bearings can better withstand bidirectional axial loads, ensuring the stability of the second lead screw 53's rotation.

[0052] In summary, this utility model achieves the effect of clamping items by coordinating the fixed block 2, the moving block 3, the transmission rod 8, and the clamping mechanism 7. The moving block 3 is moved along the base 1 by the power mechanism 9. The height and left and right position of the clamping mechanism 7 relative to the fixed block 2 are adjusted by the first lead screw and nut mechanism 4 and the third lead screw and nut mechanism 10, and the height and left and right position of the transmission rod 8 relative to the moving block 3 are adjusted by the second lead screw and nut mechanism 5 and the fourth lead screw and nut mechanism 11. This adjusts the clamping mechanism 7 to a suitable angle. In addition, a spring telescopic sleeve 71 is set in the clamping mechanism 7 to better protect the items.
