By fixing the actuation mechanism to the transmission mechanism and placing it on the side edge of the top cover, when the actuation mechanism is manually operated to move relative to the top cover, the support mechanism, fixed to the transmission mechanism, can drive the transmission mechanism to move relative to the top cover. This, in turn, drives the gripper seat to rotate relative to the top cover, allowing the grippers fixed to the gripper seat to move closer or further apart, thus enabling the clamping or loosening of the micro-titer plate. This structure makes clamping and unclamping the micro-titer plate more convenient, thereby improving operational efficiency. Attached Figure Description

[0060] See Figures 1 to 8A test fixture clamping device includes a top cover 100, gripper seats 200, grippers 300, a transmission mechanism 400, and an actuation mechanism 500. The gripper seats 200 are rotatably connected to the top cover 100. At least one pair of gripper seats 200 are provided at each of at least one set of obliquely opposite corners of the top cover 100. The grippers 300 are used to clamp workpieces and are connected to and correspond one-to-one with the gripper seats 200. The claw 300 is offset from the axis of the gripper seat 200; the transmission mechanism 400 is connected to the top cover 100 and is in transmission cooperation with the gripper seat 200; the actuation mechanism 500 is fixedly connected to the transmission mechanism 400 and is located on the side of the top cover 100, and can be operably driven to move relative to the top cover 100 to drive the gripper seat 200 to rotate relative to the top cover 100, so that the paired grippers 300 switch between open and clamped states.

[0061] This technical solution provides a test fixture clamping device, which is applied in an oscillation device 800 and used to clamp a micro-titer plate. A pair of gripper seats 200 are provided at at least one set of obliquely opposite corners of the top cover 100, and the gripper seats 200 are rotatably connected to the top cover 100. Grippers 300 are connected to the gripper seats 200 off-axis, so that when the gripper seats 200 rotate relative to the top cover 100, the distance between the two grippers 300 can decrease or increase. When the distance between the two grippers 300 is reduced to its minimum position, the grippers 300 are in a clamped state; when the distance between the two grippers 300 is increased to its maximum position, the grippers 300 are in an open state. Specifically, by providing a transmission mechanism 400 on the top cover 100 and engaging it with the gripper seat 200, the transmission mechanism 400 drives the gripper seat 200 to rotate relative to the top cover 100, thereby causing the two grippers 300 located at the same corner to switch between clamping and opening states. By fixing the actuation mechanism 500 to the transmission mechanism 400 and placing it on the side edge of the top cover 100, when the actuation mechanism 500 is manually operated to move relative to the top cover 100, the support mechanism, fixed to the transmission mechanism 400, can move relative to the top cover 100, thereby driving the gripper seat 200 to rotate relative to the top cover 100. This allows the grippers 300 fixed to the gripper seat 200 to move closer or further apart, thus achieving the clamping or releasing of the micro-titer plate. This structure makes clamping and disassembling the micro-titer plate more convenient, thereby improving operational efficiency.

[0062] It is understood that in this embodiment, the top cover 100 is constructed as a rectangular structure. In some embodiments, a pair of gripper seats 200 may be provided at one set of diagonally opposite corners of the top cover 100, or a pair of gripper seats 200 may be provided at both sets of diagonally opposite corners of the top cover 100.

[0063] The positions of the transmission mechanism 400 and the actuation mechanism 500 on the top cover 100 are not limited. The transmission mechanism 400 and the actuation mechanism 500 can be arranged on the same side as the gripper 300. In another embodiment, the transmission mechanism 400 and the actuation mechanism 500 can be arranged on two different sides. In this application, the latter is adopted. On the one hand, from the outside, only the gripper 300 is provided on the top surface of the top cover 100, which not only improves the appearance of the clamping structure, but also prevents the transmission mechanism 400 and the actuation mechanism 500 from bumping into the micro-titer plate when clamping it. On the other hand, it is also beneficial to arrange the transmission mechanism 400 and the actuation mechanism 500, thereby improving the compactness of the test vehicle clamping device.

[0064] The specific position of the actuation mechanism 500 on the top cover 100 is not limited. The actuation mechanism 500 can be set on the side of the top cover 100 along the width direction or on the side of the top cover 100 along the length direction.

[0065] like Figure 1 and Figure 4 As shown, in some embodiments, there are four gripper seats 200, each positioned in pairs at a set of diagonally opposite corners of the top cover 100. By positioning the four gripper seats 200 in pairs at a set of diagonally opposite corners of the top cover 100, the opening and closing of the two pairs of grippers 300 can be achieved by rotating the four gripper seats 200 at one set of diagonally opposite corners. This arrangement, when clamping a microtiter plate, only the clamping of the two diagonally opposite corners of the microtiter plate needs to be considered, thus facilitating the clamping of the microtiter plate. Compared to the method of setting gripper seats 200 at both sets of diagonally opposite corners, this technical solution eliminates the need to consider the degree of opening of the grippers 300 at both sets of diagonally opposite corners to prevent interference when clamping the microtiter plate.

[0066] In some embodiments, the two gripper seats 200 rotate in the same or opposite directions relative to the top cover 100 to adjust the distance between the two grippers 300.

[0067] In this embodiment, regardless of whether the two gripper seats 200 located at the same corner rotate in the same direction or in opposite directions, as long as the distance between the grippers 300 on the two gripper seats 200 can be adjusted when both rotate simultaneously, the micro-titer plate can be released or clamped. Specifically, regardless of whether the two gripper seats 200 located at the same corner rotate in the same direction or in opposite directions, when the distance between the grippers 300 on the two gripper seats 200 is at its minimum, the line connecting one gripper 300 to the axis of the gripper seat 200 connected to it is vertical; the line connecting the other gripper 300 to the axis of the gripper seat 200 connected to it is horizontal.

[0068] It is understood that the two gripper seats 200 rotating in the same direction relative to the top cover 100 means that both gripper seats 200 rotate clockwise or counterclockwise simultaneously relative to the top cover 100; while the two gripper seats 200 rotating in opposite directions relative to the top cover 100 means that one gripper seat 200 rotates clockwise relative to the top cover 100, and the other gripper seat 200 rotates counterclockwise relative to the top cover 100. The rotation direction of the two gripper seats 200 at the same angle is related to the transmission mechanism 400, as specifically described below.

[0069] like Figure 4 and Figure 5 As shown, in some embodiments, the transmission mechanism 400 includes an idler shaft 410, an idler wheel 420, two gear assemblies 430, and a timing belt 440. An idler shaft 410 is provided at each of the four corners of the top cover 100, and the idler shaft 410 is tractively connected to the top cover 100. The idler wheel 420 is tractively connected to the idler shaft 410, and the idler wheel 420 corresponds one-to-one with the idler shaft 410. Two gear assemblies 430 are respectively provided at the corners of the top cover 100 where gripper seats 200 are provided, and the gear assemblies 430 are tractively connected to the idler shaft 410. Each gear assembly 430 is tractively connected to the two gripper seats 200 at the corner. The timing belt 440 is stretched on the four idler wheels 420. The actuation mechanism 500 is fixedly connected to the timing belt 440.

[0070] By setting an idler shaft 410 at each of the four corners of the top cover 100 and connecting the idler shaft 410 to the top cover 100, and by connecting the idler 420 to the idler shaft 410, the idler 420 can be driven to rotate relative to the top cover 100 when the synchronous belt 440 stretched between the four idler 420 moves.

[0071] Based on the transmission connection between the gear assembly 430 and the idler shaft 410, and the transmission connection between the gear assembly 430 and the gripper seat 200, the gear assembly 430 is driven to run by the rotation of the idler shaft 410 relative to the top cover 100, thereby driving the gripper seat 200 to rotate relative to the top cover 100, so as to realize the switching of the gripper 300 between the clamping state and the open state.

[0072] Specifically, each idler pulley 420 has teeth extending along its axial direction on its outer peripheral surface, and the synchronous belt 440 has grooves extending along its width on its inner surface. The grooves and teeth mesh to achieve transmission between the synchronous belt 440 and the idler pulley 420. The idler pulley shaft 410 is rotatably connected to the top cover 100 via bearings.

[0073] like Figure 4 and Figure 5 As shown, specifically, each gear assembly 430 includes a driving gear 431 and two driven gears 432. The driving gear 431 is fixedly connected to the idler shaft 410, and each of the two gripper seats 200 is fixedly connected to a driven gear 432. Each driven gear 432 meshes with the driving gear 431. The two driven gears 432 are used to drive the movement of the two grippers respectively.

[0074] The driving gear 431 is fixedly connected to the end of the idler shaft 410 opposite to the idler wheel 420. When the synchronous belt 440 moves relative to the top cover 100, it drives the idler wheel 420 to rotate relative to the top cover 100, thereby causing the idler shaft 410 to rotate relative to the top cover 100. Consequently, the driving gear 431 rotates relative to the top cover 100 under the drive of the idler shaft 410. Since the driven gear 432 meshes with the driving gear 431, the rotation of the driving gear 431 can drive the two driven gears 432 to rotate relative to the top cover 100, thereby causing the gripper seat 200 to rotate relative to the top cover 100.

[0075] It is understandable that when the driving gear 431 meshes with the driven gear 432 fixedly connected to the gripper seat 200 on both radial sides, when the driving gear 431 rotates clockwise, the driven gears 432 on both sides of the driving gear 431 simultaneously rotate counterclockwise. In this structural configuration, the specific position and transmission ratio of the two grippers 300 when they are in the open state need to be considered. Specifically, when the two grippers 300 are in the open state, with... Figure 4Taking the gear assembly 430 in the upper left corner as an example, the line connecting the jaw 300 on the left jaw seat 200 and the axis of the jaw seat 200 is horizontal and positioned close to the left side of the top cover 100; the line connecting the jaw 300 on the right jaw seat 200 and the axis of the jaw seat 200 is vertical and positioned away from the upper side of the top cover 100. When the driving gear 431 rotates counterclockwise, the driven gear 432 rotates clockwise. The left jaw 300 rotates to a vertical position under the influence of the jaw seat 200 and is positioned close to the upper side of the top cover 100. The right jaw 300 rotates to a horizontal position under the influence of the jaw seat 200 and faces the left side of the top cover 100. The gear assembly 430 located in the lower right corner operates on the same principle as the one located in the upper left corner, except that the position of the gripper 300 relative to the top cover 100 is different. The specific principles will not be elaborated here. Figure 6 As shown, each gear assembly 430 further includes a reversing wheel 433 rotatably connected to the top cover 100. The reversing wheel 433 meshes with one of the two driven gears 432 and with the driving gear 431. The other driven gear 432 meshes with the driving gear 431.

[0076] In this embodiment, a reversing wheel 433 is provided between one of the driven gears 432 and the driving gear 431 to change the rotation direction of the driven gear 432 meshing with the reversing wheel 433, thereby making the rotation directions of the two driven gears 432 opposite. This arrangement allows the two grippers 300 to rotate towards each other when they need to be clamped, and to rotate away from each other when they need to be opened. This structure of the reversing wheel 433, which allows the two driven gears 432 to rotate in opposite directions, facilitates control of the clamping and opening states of the two grippers 300, thus reducing the positional requirements of the gripper seat 200 and the transmission ratio requirements between the gear assemblies 430.

[0077] It should be understood that the driven gear 432 is fixedly connected to the gripper seat 200 via the driven shaft, and the reversing wheel 433 is rotatably connected to the top cover 100 via the reversing wheel shaft.

[0078] like Figure 2As shown, in some embodiments, the top cover 100 includes a cover plate 110 and a support plate 120. The top cover 100 is configured with a receiving cavity. The gripper seat 200 is rotatably disposed on the cover plate 110, and the gripper 300 extends from the side of the cover plate 110 away from the receiving cavity. The support plate 120 is disposed in the receiving cavity. The idler wheel shaft 410 is rotatably connected to the support plate 120, and the two ends of the idler wheel shaft 410 extend out from opposite sides of the support plate 120. The idler wheel 420 and the timing belt 440 are disposed on the side of the support plate 120 away from the gripper seat 200. The gear assembly 430 is disposed between the cover plate 110 and the support plate 120.

[0079] A receiving cavity is provided on the top cover 100 to accommodate the support plate 120, transmission mechanism 400, and actuation mechanism 500, etc. Specifically, the gripper seat 200 has a cylindrical structure, and a mounting hole is provided on the top cover 100. The gripper seat 200 is rotatably disposed in the mounting hole. A gripper 300 is fixedly connected to the side of the gripper seat 200 away from the receiving cavity, and the gripper 300 is offset from the axis of the gripper seat 200. The support plate 120 is fixedly disposed in the receiving cavity on the cover plate 110, and the support plate 120 is spaced apart from the cover plate 110. The idler pulley 420 and the timing belt 440 are disposed on the side of the support plate 120 away from the gripper seat 200, so that only the idler pulley 420 and the timing belt 440 are on the side of the support plate 120 away from the gripper seat 200, thereby preventing the timing belt 440 from interfering with other components. Accordingly, the gear assembly 430 is positioned between the support plate 120 and the cover plate 110, which facilitates the distribution of the gear assembly 430 and also facilitates the rotation of the gripper seat 200 via the gear assembly 430. In this embodiment, since the idler wheel shafts 410 are positioned at the four corners of the support plate 120, the synchronous belts 440 tensioned on the four idler wheels 420 form a rectangle.

[0080] like Figure 2 and Figure 3 As shown, specifically, the actuation mechanism 500 includes a fixing component 510 and a lever 520. The fixing component 510 is fixedly connected to a section of the timing belt 440 extending along the side of the top cover 100. One end of the lever 520 is fixedly connected to the fixing component 510, and the other end passes through the guide groove 111 on the side of the top cover 100 and protrudes from the end face of the top cover 100. The lever 520 can be operably moved along the guide groove 111.

[0081] The fixing component 510 is used to establish the connection between the timing belt 440 and the lever 520. The lever 520 is used to manually apply force, thereby realizing the movement of the timing belt 440 relative to the top cover 100. Further, a sliding groove 121 extending along the thickness direction of the support plate 120 is provided at one end of the support plate 120 along its length direction, and the sliding groove 121 extends along the width direction of the support plate 120. The fixing component 510 includes a sliding seat 511, a fixing seat 512, and a fixing plate 513. The sliding seat 511 is located on the side of the support plate 120 away from the timing belt 440, and the fixing seat 512 and the fixing plate 513 are located on the side of the support plate 120 facing the timing belt 440. The sliding seat 511 has a guide protrusion matching the groove width of the sliding groove 121. One end of the lever 520 is pressed between the guide protrusion and the fixing seat 512, and the fixing seat 512 and the guide protrusion are fixed. The fixing assembly 510 is fixedly connected to the fixing base 512, which has a clearance groove for the timing belt 440 to pass through. The fixing plate 513, at one end facing the timing belt 440, has teeth that mesh with the grooves on the timing belt 440. The fixing plate 513 is fixedly connected to the fixing base 512, and the fixing plate 513 and timing belt 440 are fixedly connected by the clamping force between the fixing plate 513 and the fixing base 512, thus achieving a fixed connection between the entire fixing assembly 510 and the timing belt 440. A guide groove 111 is provided on the side of the cover plate 110. The end of the lever 520 facing away from the fixing base 512 extends from the guide groove and protrudes outside the top cover 100. The lengths of the guide groove 111 and the sliding groove 121 are approximately equal, or the length of the guide groove 111 is less than the length of the sliding groove 121.

[0082] like Figure 4 As shown, in some embodiments, the test vehicle clamping device further includes an elastic element 600, one end of which is connected to the fixing component 510 and the other end is fixedly connected to the top cover 100. The elastic element 600 provides a restoring force for the gripper 300 to switch from the open state to the clamping state. By providing the elastic element 600 between the fixing component 510 and the top cover 100, the restoring force of the elastic element 600 pulls the synchronous belt 440 to move, thereby causing the gripper 300 to return from the open state to the clamping state, and providing a preload force for locking the clamping state.

[0083] Specifically, the elastic element 600 is a spring. Two springs are spaced apart within the sliding groove 121. One end of the spring is fixedly connected to the sliding seat 511, and the other end is fixedly connected to the support plate 120, specifically to the side wall of the sliding groove 121 on the support plate 120. When the lever 520 is manually moved relative to the cover plate 110, the lever 520 drives the fixing assembly 510 to move relative to the support plate 120, thereby driving the synchronous belt to move relative to the support plate 120. The idler wheel 420 rotates relative to the support plate 120 under the drive of the synchronous belt 440, thereby driving the idler wheel shaft 410 to rotate. The driving gear 431 rotates along with the idler wheel 420 to drive the driven gear 432 to rotate relative to the cover plate 110, which in turn drives the gripper seat 200 to rotate, causing the two grippers 300 to open. During this process, the spring is stretched. When the microporous titration plate is placed on the cover plate 110, the lever 520 is released. At this time, the spring retracts and pulls the sliding seat 511 back to its original position, thereby pulling the synchronous belt 440 to move in the opposite direction, which in turn causes the two grippers 300 to switch to the clamping state and hold the microporous titration plate.

[0084] The above technical solution involves manually driving the gripper seat 200 to rotate. In another embodiment, the gripper seat 200 in this application can also be driven electrically.

[0085] like Figure 7 and Figure 8 As shown, in some embodiments, the test vehicle clamping device further includes a drive mechanism 700, which includes a drive motor 710 and a linkage sliding assembly 720. The motor mount of the drive motor 710 is fixedly connected to the base 810. One end of the linkage sliding assembly 720 is connected to the output shaft of the drive motor 710, and the other end of the linkage sliding assembly 720 is linked with the fixing assembly 510 to push the fixing assembly 510 to move relative to the top cover 100.

[0086] In this embodiment, the base 810 is the base 810 of the oscillation device 800, and the top cover 100 is placed on the base 810. The motor mount of the drive motor 710 is fixedly connected to the base 810, and the connecting rod sliding assembly 720 is connected to the output shaft of the drive motor 710, so that the output shaft of the drive motor 710 drives the connecting rod sliding assembly 720 to move. The connecting rod sliding assembly 720 is linked with the fixed assembly 510 to achieve movement of the fixed assembly 510 relative to the top cover 100, thereby driving the synchronous belt 440 to move relative to the top cover 100.

[0087] Specifically, the linkage sliding assembly 720 includes a first linkage 721, a second linkage 722, a slider 723, and a paddle 724. One end of the first linkage 721 is connected to the output shaft of the drive motor 710; one end of the second linkage 722 is hinged to the other end of the first linkage 721; one end of the slider 723 is hinged to the second linkage 722, and the slider 723 slides in the guide groove on the base 810; one end of the paddle 724 is fixedly connected to the slider 723, and the other end is bent and abuts against one end of the fixing assembly 510.

[0088] By connecting the first link 721 to the output shaft of the drive motor 710, the rotation of the output shaft of the drive motor 710 drives the first link 721 to rotate. Since one end of the second link 722 is hinged to the end of the first link 721 opposite to the output shaft, the first link 721 can drive the second link 722 to rotate. The end of the second link 722 opposite to the first link 721 is hinged to the slider 723. Since the slider 723 slides in the positioning groove 811 on the base 810, the slider 723 can only move along the extension direction of the positioning groove 811. Therefore, the second link 722 can only pull the slider 723 to move along the positioning groove 811. Since a lever 724 is connected to the slider 723, one end of the lever 724 is bent and can abut against one end of the fixing component 510. Thus, during the movement of the slider 723 relative to the positioning groove 811, the lever 724 can drive the fixing component 510 to move relative to the top cover 100, thereby driving the synchronous belt 440 to move.

[0089] An embodiment of this utility model also provides an oscillation device, which includes the test carrier clamping device as described above.

[0090] Specifically, a rotating shaft is installed on the base of the oscillation device, and the top cover is fixedly connected to the rotating shaft. The top cover rotates relative to the base under the drive of the rotating shaft. The micro-titer plate is clamped onto the top cover by a test fixture clamping device, thus facilitating the circular motion of the micro-titer plate holder as the rotating shaft drives the top cover relative to the base. By applying the above-mentioned test fixture clamping device to the oscillation device, the clamping and disassembly of the micro-titer plate becomes more convenient, thereby improving operational efficiency.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
