Description

Technical Field

[0001] This utility model relates to the field of positioning technology for perforated plates, and specifically to a clamping mechanism for rinsing perforated plates. Background Technology

[0002] Perforated plates are plates with multiple through holes on their surface. In fields such as biological experiments, it is necessary to limit the position of reagents and samples through the through holes so that the same perforated plate can hold a large number of reagents and samples. During the experiment or movement, biological samples inevitably contaminate the surface of the perforated plate, so it needs to be cleaned after use.

[0003] Currently, a utility model patent with announcement number CN221453543U discloses a clamping device for forging support production, including a base with a fixed plate movably connected to the base, a clamping mechanism, and a rinsing mechanism. The rinsing mechanism is set on the base and is used to clamp the forging. The rinsing mechanism is set on the connecting platform and is used to rinse sand or metal impurities from the surface of the forging. The slider moves left and right through the screw sleeve on the bidirectional screw, and the fixed plate fixed on the slider clamps the forging from left and right. Finally, the surface of the forging is rinsed by high-pressure spray.

[0004] In existing technologies, when cleaning perforated plates, in order to ensure that water can flow out through the through holes, a counter-clamping method is mostly used to fix the plate in the air, so that the plate is positioned in the air and then rinsed by cleaning equipment. For example, the bidirectional screw counter-drive method mentioned above is one of the commonly used clamping and positioning methods. This method can prevent the clamping structure from blocking the through holes, thereby ensuring the effectiveness of rinsing inside the through holes. However, for mechanical clamping, in order to ensure the stability of clamping, the applied pressure needs to overcome the weight of the perforated plate. During long-term use, this can easily lead to wear on the edges of the perforated plate, affecting its use. In order to ensure the effectiveness of rinsing and the stability of positioning, this application provides a clamping mechanism for rinsing perforated plates to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a clamping mechanism for rinsing perforated plates, which solves the problem that the positioning and clamping action of perforated plates during cleaning in the prior art easily leads to wear on the edges of the plates.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A clamping mechanism for rinsing perforated plates includes a base, a vertical box and a tray on the base, a storage plate placed in the tray, a hydraulic cylinder in the vertical box, a connecting shell on the piston end of the hydraulic cylinder, and the connecting shell moving closer to or further away from the tray in the vertical direction by the drive of the hydraulic cylinder. A rotating arm is rotatably connected to the bottom of the connecting shell, and a clamping module is provided on the rotating arm. The clamping module is located above the tray. The clamping module includes a fixed box located at the bottom of the rotating arm. The fixed box contains opposing moving modules. Both moving ends of the opposing moving modules are provided with support members. The cross-section of the support members is L-shaped. The placement plate can be placed between the opposite sides of the two support members.

[0007] The above technical solution drives two supporting components to move in opposite directions through a countermoving module, enabling the supporting components to open and close normally, pass over the shelf, and then close to lift the shelf, thus meeting the lifting and positioning requirements.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, a DC motor is provided on the connecting shell, and a drive shaft is fixed on the rotating arm. The outer side of the drive shaft is rotatably connected to the bottom of the connecting shell through a bearing, and the output shaft of the DC motor passes through the top of the connecting shell and is fixed to the top of the drive shaft. The fixed box is located on the side of the bottom of the rotating arm away from the drive shaft, and the outside of the upright box is provided with a vertical sliding hole for the connecting shell to pass through and slide.

[0010] The above technical solution allows the DC motor to drive the rotating arm to rotate via the drive shaft; the vertical movement hole allows the connecting shell to be moved normally by the hydraulic cylinder.

[0011] Furthermore, the support includes a movable plate, and each of the two movable plates is provided with a clamping piece on its opposite side. The bottom of the clamping piece is provided with two lower edges, and a support piece is provided on the outer side of the lower edges. The two lower edges are symmetrically distributed, and the support piece is arranged parallel to the tray.

[0012] The above technical solution enables the support plate to support the shelf.

[0013] Furthermore, the tray is provided with a limiting groove for placing the shelf, and several through holes for the lower edge and support plate to move. The shelf has evenly distributed through holes, the distance between the outermost through hole and the outer side of the shelf is L1, and the length of the support piece is L2, where L1>L2.

[0014] The above technical solution ensures that the support plate will not block the through holes on the shelf.

[0015] Furthermore, the opposing moving module includes a motor and an assembly plate housed in a fixed box. The assembly plate is provided with two slide rails, and a slider is slidably connected to the outside of the slide rails. A push-pull plate is provided on the slider. Both of the two push-pull plates have toothed plates on opposite sides. The output shaft of the first motor passes through the assembly plate and is fitted with a gear. Both toothed plates mesh with the gear. The two toothed plates are centrally symmetrical about the gear. The output shaft of the first motor is rotatably connected to the outside of the assembly plate through a bearing.

[0016] The above technical solution enables the gear to drive two racks to move in opposite directions.

[0017] Furthermore, the opposite sides of the two push-pull plates are respectively fixed to the outer side of the two movable plates, and the outer side of the fixed box is provided with two push-pull holes for the two push-pull plates to move.

[0018] The above technical solution enables the push-pull plate to move normally within the corresponding push-pull hole.

[0019] Furthermore, the opposing moving module includes a bidirectional lead screw rotatably connected to the fixed box via a bearing. Two sliders are threadedly connected to the outside of the bidirectional lead screw. The two sliders are symmetrically distributed, and a linkage plate is provided on the outside of the sliders. The fixed box is equipped with a second motor and a second slide rail for the two second sliders to slide together. The output shaft of the second motor and the outer side of the bidirectional lead screw are both fitted with synchronous pulleys, and a synchronous belt meshes between the outer sides of the two synchronous pulleys.

[0020] The above technical solution enables two sliders to move in opposite directions via a bidirectional lead screw; and through the transmission of the synchronous pulley and synchronous belt, the motor can provide power for the rotation of the bidirectional lead screw.

[0021] Furthermore, the opposite sides of the two linkage plates are respectively fixed to the outer sides of the two movable plates, and the outer side of the fixed box is provided with two movable holes for the two movable plates to slide.

[0022] The above technical solution enables the mobile board to operate normally.

[0023] Furthermore, a support base is provided inside the fixed box, and the output shaft of the second motor is rotatably connected to the support base through a bearing.

[0024] The above technical solution can provide stability for the two output shafts of the motor.

[0025] Furthermore, the fixed box is provided with two limiting blocks, and the limiting blocks have round holes for the bidirectional lead screw to pass through. The outer side of the bidirectional lead screw is rotatably connected to the round hole through a bearing. The two limiting blocks are symmetrically distributed on both sides of the synchronous pulley.

[0026] The above technical solution enables the bidirectional lead screw to rotate more stably.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. The opposing clamping action of the clamping module can meet the clamping and placement requirements of shelves of different sizes; and under the support of the support plate, the lifting method can be used to replace clamping and positioning, so that the shelf can be lifted in the air to wait for washing, preventing excessive wear on the outer wall of the shelf. 2. The rotating arm is driven by a DC motor, which allows the shelf supported by the support plate to move closer to or further away from the tray, so that the shelf can be rinsed and cleaned on the side away from the tray. After rinsing, the rotating arm puts it back on the tray. The whole process is highly automated and convenient to use. Attached Figure Description

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Example 1:

[0032] refer to Figure 1 A clamping mechanism for rinsing perforated plates includes a base 1, a vertical box 2 and a tray 6 on the base 1, a shelf 7 placed in the tray 6, a hydraulic cylinder in the vertical box 2, a connecting shell 3 on the piston end of the hydraulic cylinder, the connecting shell 3 being driven by the hydraulic cylinder to move closer to or further away from the tray 6 in the vertical direction; a rotating arm 4 is rotatably connected to the bottom of the connecting shell 3, a clamping module 5 is provided on the rotating arm 4, the clamping module 5 is located above the tray 6; the clamping module 5 includes a fixed box 51 located at the bottom of the rotating arm 4, a countermoving module is provided in the fixed box 51, both moving ends of the countermoving module are provided with support members, the cross-section of the support members is L-shaped, and the shelf 7 can be placed between the two opposite sides of the support members.

[0033] It should be noted that the outer side of the vertical box 2 is provided with a vertical sliding hole for the connecting shell 3 to pass through and slide. The connecting shell 3 can be moved normally by the hydraulic cylinder through the vertical sliding hole.

[0034] It should also be noted that a rinsing device is provided next to the base 1, which can rinse the shelf 7 that has been moved to the outside of the tray 6. The rinsing device can be any existing rinsing device such as a water spray pipe, so it will not be described in detail.

[0035] refer to Figure 2 and Figure 3 A DC motor 31 is provided on the connecting shell 3, and a drive shaft 32 is fixed on the rotating arm 4. The outer side of the drive shaft 32 is rotatably connected to the bottom of the connecting shell 3 through a bearing. The output shaft of the DC motor 31 passes through the top of the connecting shell 3 and is fixed to the top of the drive shaft 32, so that the DC motor 31 can drive the rotating arm 4 to rotate through the drive shaft 32. The fixed box 51 is located on the bottom of the rotating arm 4 away from the drive shaft 32, so that the fixed box 51 can be driven by the rotating arm 4 to make arc-shaped displacement.

[0036] It should be noted that the output shaft of the DC motor 31 is equipped with an encoder, which can emit certain pulses when the output shaft rotates, thereby determining the rotation angle value, or other sensors with angle sensing function can be used to achieve this effect. All of these are existing publicly available motor drive technologies, which enable the drive angle of the DC motor 31 to be fixed.

[0037] In use, the DC motor 31 drives the rotating arm 4 to move above the tray 6 via the drive shaft 32, the hydraulic cylinder drives the connecting shell 3 to move down, and the clamping module 5 positions the placement plate 7; finally, the hydraulic cylinder lifts the placement plate 7 through the connecting shell 3, the rotating arm 4 and the clamping module 5, and the rotating arm 4 drives the placement plate 7 away from the tray 6, so that the rinsing work can be started.

[0038] refer to Figure 3 and Figure 5 The support includes a movable plate 52. Each of the two movable plates 52 has a clamping piece 53 on one side facing away from each other. The bottom of the clamping piece 53 has two lower edges 531. A support piece 54 is provided on the outer side of the lower edge 531. The two lower edges 531 are symmetrically distributed. The support piece 54 is set parallel to the tray 6 so that the support piece 54 can support the shelf 7.

[0039] refer to Figure 2 and Figure 3 The tray 6 has a limiting groove 61 for placing the shelf 7, and several through holes 62 for the lower edge 531 and the support plate 54 to move, so that the lower edge 531 and the support plate 54 can move normally through the through holes 62 to the bottom of the shelf 7, which facilitates subsequent lifting actions.

[0040] refer to Figure 3 and Figure 4 The shelf 7 has evenly distributed through holes. The distance between the outermost through hole and the outer side of the shelf 7 is L1. The length of the support piece 54 is L2, where L1>L2. Specifically, the length of the support piece 54 in contact with the bottom of the shelf 7 is less than the distance between the inner wall of the outermost through hole and the adjacent clamping piece 53, so that the support piece 54 can support the shelf 7 and will not block the through holes on the shelf 7, allowing the water or cleaning agent to pass through the through holes normally.

[0041] In use, the opposing moving module drives the two clamping pieces 53 to open and close, so that the clamping pieces 53 can be located on the outside of the shelf 7. The connecting shell 3 drives the clamping pieces 53 to descend together, so that the lower edge 531 and the support piece 54 can move to the bottom of the shelf 7. The opposing moving module drives the two clamping pieces 53 to close, so that the support piece 54 moves below the shelf 7. The connecting shell 3 drives the clamping pieces 53 to rise together, so that the support piece 54 fits against the bottom of the shelf 7, completing the lifting action.

[0042] refer to Figure 6 The opposing moving module includes a motor 55 and an assembly plate 56 housed in a fixed box 51. The assembly plate 56 is provided with two slide rails 57. A slider 58 is slidably connected to the outside of the slide rails 57, so that the slider 58 can slide on the outside of the corresponding slide rail 57. The slider 58 is provided with a push-pull plate 59. The opposite sides of the two push-pull plates 59 are respectively fixed to the outside of the two moving plates 52. The outside of the fixed box 51 is provided with two push-pull holes for the two push-pull plates 59 to move, so that the push-pull plates 59 can move normally in the corresponding push-pull holes.

[0043] refer to Figure 6 Each of the two push-pull plates 59 has a toothed plate 510 on one side opposite to the other. The output shaft of the motor 55 passes through the mounting plate 56 and is fitted with a gear 511. Both toothed plates 510 mesh with the gear 511. The two toothed plates 510 are centrally symmetrically distributed with the gear 511 as the center. The output shaft of the motor 55 is rotatably connected to the outside of the mounting plate 56 through a bearing, so that the gear 511 can drive the two racks to move in opposite directions.

[0044] In use, the motor 55 drives the gear 511 to rotate, causing the two gear plates 510 to move in opposite directions. With the sliding cooperation of the slider 58 and the slide rail 57, the slider 58 can drive the push-pull plate 59 to move, thereby realizing the opening and closing or closing of the two moving plates 52. Example 2:

[0045] refer to Figure 7 This embodiment is largely the same as Embodiment 1, except that the opposing moving module includes a bidirectional lead screw 81 rotatably connected to the fixed box 51 via bearings. Two sliders 82 are threadedly connected to the outside of the bidirectional lead screw 81. The two sliders 82 are symmetrically distributed and can be driven by the bidirectional lead screw 81 to move in opposite directions. A linkage plate 83 is provided on the outside of the sliders 82. The opposite sides of the two linkage plates 83 are fixed to the outside of the two moving plates 52 respectively. The outside of the fixed box 51 is provided with two moving holes for the two moving plates 52 to slide, so that the moving plates 52 can move normally.

[0046] refer to Figure 7 The fixed box 51 contains a motor 85 and a slide rail 84 for two sliders 82 to slide together. The output shaft of the motor 85 and the outer side of the bidirectional lead screw 81 are both fitted with synchronous pulleys 87. The outer sides of the two synchronous pulleys 87 are meshed with a synchronous belt 88. Through the transmission of the synchronous pulleys 87 and the synchronous belt 88, the motor 85 can provide power for the rotation of the bidirectional lead screw 81.

[0047] In use, motor 85 drives the bidirectional lead screw 81 to rotate through synchronous pulley 87 and synchronous belt 88. With the sliding cooperation of slider 82 and slide rail 84, the two sliders 82 can move in opposite directions, which in turn drives the two moving plates 52 to open or close through linkage plate 83.

[0048] refer to Figure 7 The fixed box 51 is equipped with a support base 86. The output shaft of the second motor 85 is rotatably connected to the support base 86 through a bearing, which can provide stability during the transmission process of the output shaft of the second motor 85.

[0049] refer to Figure 7 The fixed box 51 is provided with two limit blocks 89. The limit blocks 89 have round holes for the bidirectional lead screw 81 to pass through. The outer side of the bidirectional lead screw 81 is rotatably connected to the round hole through a bearing. The two limit blocks 89 are symmetrically distributed on both sides of the synchronous pulley 87, which can make the bidirectional lead screw 81 rotate more stably.
