Description

Technical Field

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

[0002] Well plates are a very common and crucial instrument in biological experiments. Their main function is to provide multiple, independent storage spaces for small reagent samples. Depending on the type of biological contamination, the cleaning standards for well plates vary. For well plates that require simple rinsing, the common method is to move the well plate to a clamping device for positioning, then clean it using a rinsing device, and finally remove the rinsed well plate to complete the cleaning process.

[0003] Currently, a utility model patent with announcement number CN213001336U discloses a high-efficiency cleaning and maintenance device for medical equipment. This patent includes a support plate, clamping components, a motor, and a brush. Two sets of baffles are fixed to the bottom wall of the support plate, and pads are fixed to the bottom ends of both sets of baffles. A moving device is provided between the two sets of baffles. Two sets of vertical plates are fixed to the top wall of the support plate, and a top plate is fixed to the top of the two sets of vertical plates. A motor, a brush, and an adjusting component are provided between the two sets of vertical plates. The motor is connected to the adjusting component via bolts, and the motor's output shaft is connected to a flange. The flange is connected to the brush via bolts. A water storage tank is provided below the brush, and the four inner walls of the water storage tank are integrally formed with support blocks for supporting a perforated plate. Two sets of clamping components are provided, each connected to one of the two sets of vertical plates. By using the two sets of clamping components that move in opposite directions, equipment of different volumes can be fixed, improving cleaning efficiency.

[0004] In the prior art, when cleaning plates, the positioning method is mostly carried out as described above. This clamping and positioning method mainly relies on manual judgment of the position when correcting the position of the plate. If there is a deviation in the placement position, it will lead to the problem that some areas cannot be effectively cleaned during the rinsing process. In this regard, this application provides a positioning mechanism for a clamping device for cleaning perforated plates to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a positioning mechanism for a clamping device for perforated plate cleaning, in order to solve the problem that the existing plate positioning mechanism cannot guarantee that the positioning point remains accurate every time during continuous operation.

[0006] The technical solution of this utility model to solve the above technical problems is as follows: A positioning mechanism for a clamping device for cleaning perforated plates includes a chassis, a support plate on the chassis, a perforated plate placed on the support plate, and a driving mechanism. The driving mechanism is provided with rotating modules that can be driven to move, and the rotating modules can all move in the vertical direction. The rotating module is provided with a swing arm that swings above the support plate. A fixed-point module is provided between the swing arm and the opposite side of the rotating module. A lifting component is provided at the bottom of the swing arm to lift the perforated plate. The positioning module includes two sensors located at the bottom of the rotating module and a trigger located at the top of the swing arm. The trigger can be moved to the outside of the sensors.

[0007] Through the above technical solution, the rotating module can be stopped after rotating to the corresponding angle by the cooperation of the sensing and triggering components; the driving mechanism can drive the rotating module, swing arm and lifting component to move in the vertical direction, and then the lifting component can lift the perforated plate on the support plate to facilitate rinsing by external cleaning equipment.

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

[0009] Furthermore, the rotating module includes a lifting box and a linear motor, with the linear motor located inside the lifting box and a rotation hole provided at the bottom of the lifting box; The top of the swing arm is fixed with a shaft, which is rotatably connected to the rotating hole through a bearing, and the output shaft of the linear motor is fixed to the end of the shaft.

[0010] The above technical solution enables a linear motor to drive the shaft and swing arm to rotate.

[0011] Furthermore, the sensing element includes a second photoelectric switch disposed at the bottom of the lifting box, and the two second photoelectric switches are disposed on the same straight line, and the straight line is perpendicular to the front of the lifting box; The trigger includes a first light-blocking plate and a second light-blocking plate disposed at the top of the swing arm. The included angle between the first light-blocking plate and the second light-blocking plate is α, where α = 90°. The first light-blocking plate and the second light-blocking plate can be moved to the outside of the two second photoelectric switches, respectively.

[0012] The above technical solution allows the first and second light-blocking sheets to block the two second photoelectric switches respectively, achieving the effect of induction detection.

[0013] Furthermore, the lifting assembly includes a support box located at the bottom of the swing arm, the support box being located on the side of the swing arm away from the linear motor, and the support box containing a servo motor and a bearing plate; The output shaft of the servo motor is rotatably connected to the bearing plate through the bearing. The output shaft of the servo motor passes through the bearing plate and is fitted with a gear. Two racks mesh on the outer side of the gear, and a support component is provided on the opposite side of the two racks.

[0014] The above technical solution uses a servo motor to drive a gear that moves two racks in opposite directions, which changes the distance between the two lifting components and facilitates the lifting of the perforated plate.

[0015] Furthermore, the lifting component includes a connecting plate located on the outside of the rack, and a fixing plate on each of the two connecting plates facing away from each other. The fixing plate is provided with a clamping plate, which is inverted U-shaped. The bottom of the clamping plate is provided with two bent portions, which are bent toward the side closer to the support box and are set parallel to the ground. The support plate has several clamping holes for the bottom and bending part of the clamping plate to move.

[0016] The above technical solution enables the bent part to move normally through the clamping hole to the bottom of the perforated plate, facilitating the lifting action.

[0017] Furthermore, the support box has extension holes on its outer side for two connecting plates to pass through and slide, the bearing plate has two fixed sliders, and the connecting plate has a guide rail on the side near the bearing plate. The guide rail is slidably connected to the corresponding fixed slider.

[0018] The above technical solution enables the guide rail to move smoothly under the constraint of the corresponding fixed slider.

[0019] Furthermore, the drive mechanism includes a drive box mounted on the chassis, a hydraulic cylinder inside the drive box, a lifting plate at the piston end of the hydraulic cylinder, a limit guide rail and two first photoelectric switches inside the drive box.

[0020] The above technical solution enables the lifting plate to be lifted by a hydraulic cylinder.

[0021] Furthermore, the outer side of the lifting plate is provided with a light-blocking part, and the lifting plate is provided with a sliding groove that matches the outer side of the limiting guide rail. The top and bottom of the sliding groove are both open. The two first photoelectric switches are located in the same vertical plane, and the light-blocking part corresponds to the position of the first photoelectric switch. The light-blocking part can be moved to the outside of the first photoelectric switch.

[0022] By using the above technical solution, the first photoelectric switch can be triggered by blocking the light-blocking part, which can locate the position of the lifting plate.

[0023] Furthermore, the lifting plate is fixedly connected to the lifting box, and the drive box has a movable hole for the lifting box and the lifting plate to be inserted and slid at the connection point.

[0024] The above technical solution enables the lifting box to move normally by being driven by the lifting plate.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. The lifting component can be moved above the support plate by rotating the module and swinging the arm, so that the lifting component can easily clamp and lift the perforated plate placed on the support plate; and under the limiting action of the positioning module, the swing angle can be fixed, thereby meeting the requirements of accurate positioning and positioning cleaning. 2. Under the action of the lifting component, the bottom of the perforated plate can be lifted and positioned by the opposing clamping action, which can provide a gentle and stable positioning effect and facilitate subsequent cleaning work.

[0028] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. 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.

[0029] 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.

[0030] Example: Reference Figure 1 A positioning mechanism for a clamping device for cleaning perforated plates includes a chassis 1, a support plate 2 on the chassis 1, a perforated plate 4 placed on the support plate 2, and a drive mechanism 3. The drive mechanism 3 has rotating modules 5 that can be moved by it, and each rotating module 5 can move in the vertical direction. The rotating modules 5 have swing arms 6 that swing above the support plate 2. A fixed point module 7 is provided between the swing arms 6 and the opposite side of the rotating modules 5. The bottom of the swing arms 6 has a lifting component 8 that lifts the perforated plate 4. The fixed point module 7 includes two sensors located at the bottom of the rotating modules 5 and a trigger located at the top of the swing arms 6. The trigger can be moved to the outside of the sensors.

[0031] It should be noted that the chassis 1 is equipped with a linear transmission module that drives the support plate 2 to move linearly, and the linear transmission module is equipped with several proximity switch sensors; the side of the linear transmission module near the swing arm 6 has two proximity switch sensors, and the support plate 2 has two grooves for placing the perforated plate.

[0032] It should also be noted that when the linear transmission module stops due to the trigger signals of two proximity switch sensors near the side of the swing arm 6, the swing arm 6 can drive the lifting assembly 8 to rotate above the perforated plate near the side of the drive mechanism 3; the drive mechanism 3 drives the lifting assembly 8 to move vertically through the rotation module 5 and the swing arm 6, so that the lifting assembly 8 can properly clamp and position the perforated plate 4 on the support plate 2.

[0033] In addition, the cleaning machine for cleaning the perforated plate 4 is set on the ground or other base layer on the front side of the chassis 1. The cleaning machine can be a cleaning structure composed of multiple water pipes. When the swing arm 6 drives the lifting assembly 8 and the perforated plate 4 clamped and positioned by the lifting assembly 8 away from the support plate 2, the perforated plate 4 at this position can be rinsed and cleaned by the water pipe rinsing function of the cleaning machine.

[0034] refer to Figure 1 and Figure 2The rotating module 5 includes a lifting box 51 and a linear motor 52. The linear motor 52 is located inside the lifting box 51, and a rotation hole is provided at the bottom of the lifting box 51. A shaft is fixed at the top of the swing arm 6. The shaft is rotatably connected to the rotation hole through a bearing. The output shaft of the linear motor 52 is fixed to the end of the shaft. The linear motor 52 can drive the shaft and the swing arm 6 to rotate.

[0035] refer to Figure 2 and Figure 4 The sensing element includes a second photoelectric switch 73 located at the bottom of the lifting box 51. The two second photoelectric switches 73 are arranged on the same straight line, and the straight line is perpendicular to the front of the lifting box 51, which facilitates the subsequent blocking by the first light-blocking plate 71 and the second light-blocking plate 72. The triggering element includes a first light-blocking plate 71 and a second light-blocking plate 72 located at the top of the swing arm 6. The included angle between the first light-blocking plate 71 and the second light-blocking plate 72 is α, where α = 90°. By limiting the angle by 90°, the swing arm 6 can always rotate back and forth on two mutually perpendicular sides. The first light-blocking plate 71 and the second light-blocking plate 72 can be moved to the outside of the two second photoelectric switches 73, respectively. Specifically, the first light-blocking plate 71 can be moved to the outside of the second photoelectric switch 73 on the front side, and the second light-blocking plate 72 can be moved to the outside of the second photoelectric switch 73 on the back side. The first light-blocking plate 71 and the second light-blocking plate 72 can block the two second photoelectric switches 73 respectively, thereby achieving the effect of sensing and detection.

[0036] In use, the linear motor 52 drives the swing arm 6 to rotate via the shaft. When the first light-blocking plate 71 blocks the corresponding second photoelectric switch 73, the lifting component 8 is located above the corresponding perforated plate. When the second light-blocking plate 72 blocks the corresponding second photoelectric switch 73, the lifting component 8 is located on the side away from the support plate 2, which facilitates subsequent rinsing and cleaning work and will not contaminate the support plate 2.

[0037] refer to Figure 1 and Figure 5The lifting assembly 8 includes a support box 81 located at the bottom of the swing arm 6. The support box 81 is located on the side of the swing arm 6 away from the linear motor 52. The support box 81 contains a servo motor 82 and a bearing plate 83. The output shaft of the servo motor 82 is rotatably connected to the bearing plate 83 through a bearing, so that the bearing plate 83 can support the output shaft of the servo motor 82 through the bearing. The output shaft of the servo motor 82 passes through the bearing plate 83 and is fitted with a gear 84. Two racks 85 are meshed on the outer side of the gear 84. The servo motor 82 drives the gear 84 to drive the two racks 85 to move in opposite directions. Lifting members 86 are provided on the opposite sides of the two racks 85. Through the opposite movement of the two racks 85, the distance between the two lifting members 86 can be changed so that the distance between the two lifting members 86 can be greater than the edge line of the perforated plate, so that they can move normally under the perforated plate and facilitate the lifting of the perforated plate.

[0038] refer to Figure 2 and Figure 5 The lifting component 86 includes a connecting plate 861 located on the outside of the rack 85. Each of the two connecting plates 861 has a fixing plate 862 on its opposite side. The fixing plate 862 has a clamping plate 863, which is inverted U-shaped. The bottom of the clamping plate 863 has two bent portions 864, which bend towards the side closer to the support box 81 and are parallel to the ground. The support plate 2 has several clamping holes for the bottom of the clamping plate 863 and the bent portions 864 to move, so that the bent portions 864 can move normally through the clamping holes to the bottom of the perforated plate, which facilitates the lifting action.

[0039] refer to Figure 2 and Figure 5 The support box 81 has extension holes on its outer side for two connecting plates 861 to pass through and slide. The extension holes allow the connecting plates 861 to move normally. The bearing plate 83 has two fixed sliders 88. The connecting plate 861 has a guide rail 87 on the side near the bearing plate 83. The guide rail 87 is slidably connected to the corresponding fixed slider 88. Through the sliding cooperation between the guide rail 87 and the fixed slider 88, the guide rail 87 can move smoothly under the restriction of the corresponding fixed slider 88, thereby allowing the connecting plate 861 to move smoothly.

[0040] refer to Figure 3 The drive mechanism 3 includes a drive box 31 mounted on the chassis 1. The drive box 31 contains a hydraulic cylinder 32. The piston end of the hydraulic cylinder 32 is provided with a lifting plate 34. The drive box 31 contains a limit guide rail 35 and two first photoelectric switches 36. The hydraulic cylinder 32 can drive the lifting plate 34 to perform vertical lifting and sliding movements.

[0041] refer to Figure 3The lifting plate 34 has a light-blocking part on its outer side, and a sliding groove that matches the outer side of the limiting guide rail 35 is opened on the lifting plate 34. The top and bottom of the sliding groove are open. The two first photoelectric switches 36 are located in the same vertical plane. The light-blocking part corresponds to the position of the first photoelectric switch 36. The light-blocking part can be moved to the outside of the first photoelectric switch 36. By blocking the first photoelectric switch 36 with the light-blocking part, the sensor can be triggered, and the position of the lifting plate 34 can be located.

[0042] refer to Figure 2 and Figure 3 The lifting plate 34 is fixedly connected to the lifting box 51, so that the lifting box 51 can be driven by the lifting plate 34 to move synchronously. The drive box 31 is provided with a moving hole 33 for the connection between the lifting box 51 and the lifting plate 34 to be inserted and slid. The moving hole 33 allows the lifting plate 34 to drive the lifting box 51 to move normally.

[0043] In use, the hydraulic cylinder 32 drives the lifting plate 34 to move, which in turn drives the lifting box 51 to move vertically, so that the swing arm 6 moves synchronously, allowing the support box 81 and the lifting member 86 to move closer to or further away from the support plate 2.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
