Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of biological experiment equipment, in particular to an automatic multi-station hole plate washing machine. BACKGROUND

[0002] In biological experiments, hole plates are often washed. The manual hole plate washing method mainly involves holding the hole plate in the hand with the hole facing outward, and then swinging the hole plate to shake off the liquid in the hole plate. This method is relatively convenient, but the washing effect is different depending on the swinging speed of different operators, and the cleaning consistency is poor. Moreover, when the number of hole plates is large, the operator will be very tired.

[0003] There are two types of automatic hole plate washing machines on the market. One type is a washing head and a washing machine assembly as disclosed in patent CN102794273. The method for washing the hole plate mainly involves injecting liquid into the hole plate and then pumping out the liquid. However, this method cannot completely pump out the liquid in the hole plate, and there is liquid residue in the hole. The other type of hole plate washing machine is a vertical centrifugal hole plate washing machine. The disadvantage of this type of patent is that the hole plate needs to be placed vertically into the washing machine, and then the liquid in the hole plate is shaken out by centrifugal force. This inevitably causes the liquid in the hole plate to flow out during the vertical placement of the hole plate, resulting in contamination between the holes. SUMMARY

[0004] The purpose of the present application is to provide an automatic multi-station hole plate washing machine that can ensure less liquid residue after washing the hole plate and avoid cross contamination caused by liquid overflow between the holes.

[0005] To solve the above problems, the present application provides an automatic multi-station hole plate washing machine, which comprises:

[0006] A centrifugal assembly, comprising a centrifugal turntable, a centrifugal motor and a plurality of receiving frames, the centrifugal turntable is driven by the centrifugal motor to rotate around a vertical axis, and the plurality of receiving frames are arranged circumferentially on the outer periphery of the centrifugal turntable;

[0007] A plurality of receiving assemblies correspond to the receiving frames one by one, the receiving assembly comprises a receiving disc, an adapter rod and a swing rod; when the centrifugal turntable is in a stationary state, the receiving disc is in a horizontal state, the upper side of the receiving disc is provided with a resting area for fixing a target piece, the middle part of the receiving disc is rotationally connected to the corresponding receiving frame with the rotation axis being transverse and perpendicular to the radial direction of the centrifugal turntable, the adapter rod and the swing rod are both located below the receiving disc, the middle part of the swing rod is rotationally connected to the corresponding receiving frame with the rotation axis being transverse and perpendicular to the radial direction of the centrifugal turntable, the lower end of the swing rod is provided with a weight pendulum, one end of the adapter rod is rotationally connected to the upper end of the swing rod and the other end is rotationally connected to the side of the receiving disc away from the centrifugal turntable with the rotation axis being transverse and perpendicular to the radial direction of the centrifugal turntable;

[0008] When the centrifugal motor drives the centrifugal turntable to rotate, the lower end of the swing rod is away from the centrifugal turntable due to the centrifugal force of the weight swing hammer, and at this time the upper end of the swing rod drives the receiving disc to move along the direction of downward and close to the centrifugal turntable through the connecting rod, so that the receiving disc is rotated to the vertical state.

[0009] In the above scheme, the resting area of the receiving disc is used for placing and fixing the target object such as the hole plate, when the centrifugal turntable is in a static state, the receiving disc is in a horizontal state, so the hole plate can be placed horizontally in the resting area, avoiding the problem of cross contamination caused by the vertical placement of the hole plate; when it is necessary to clean the hole plate, the centrifugal motor drives the centrifugal turntable to rotate, the centrifugal turntable drives the receiving disc to rotate, and the lower end of the swing rod is away from the centrifugal turntable due to the centrifugal force of the weight swing hammer, so the upper end of the swing rod drives the side of the receiving disc away from the centrifugal turntable to move along the direction of downward and close to the centrifugal turntable through the connecting rod, so that the receiving disc and the hole plate are gradually rotated to the vertical state, and at this time, due to the existence of the centrifugal force, the liquid in the hole of the hole plate will be directly thrown out without cross contamination, and the rotation speed of the centrifugal motor corresponds to the degree of spin-drying cleaning of the hole plate, which is efficient and stable in cleaning effect.

[0012] In an improved scheme, the rotation axis of the rotationally connected locking block and receiving disc is transversely and perpendicularly to the radial direction of the centrifugal turntable, and the end of the locking block provided with the hook is further provided with a weight swing pin, so that when the centrifugal turntable rotates, due to the greater centrifugal force of the weight swing pin, the side of the locking block provided with the hook will further protrude from the upper end surface of the receiving disc, realizing the more stable limiting function of the target piece.

[0013] In an improved scheme, the transverse section of the receiving frame is U-shaped and the U-shaped opening faces away from the centrifugal rotating table, and the receiving assembly is located in the U-shaped opening of the receiving frame, so that the connection is stable and the structure is compact.

[0014] In an improved scheme, the receiving frames are uniformly spaced from each other, so as to ensure stability during rotation of the centrifugal frame.

[0015] In an improved scheme, a waste liquid collecting assembly is further included, which comprises a waste liquid collecting cover in the shape of a cylinder with an axis vertically arranged around the centrifugal assembly, and a ring-shaped liquid collecting disc is arranged at the lower part of the inner circumferential wall of the waste liquid collecting cover, so that when the centrifugal rotating table rotates, the liquid thrown out from the hole plate of the resting area will be blocked by the waste liquid collecting cover and collected in the liquid collecting disc.

[0016] In an improved scheme, the waste liquid collecting assembly further comprises a lifting driving member and a lifting frame, the output end of the lifting driving member acts on the lifting frame to drive the lifting of the lifting frame, and the waste liquid collecting cover is connected to the lifting frame, so that when the lifting driving member drives the lifting frame to move to a position around the centrifugal rotating table, the liquid thrown out by the hole plate due to the rotation of the centrifugal rotating table will be guided to the liquid collecting disc by the waste liquid collecting cover, and when the lifting driving member drives the lifting frame to move to a position above or below the centrifugal rotating table, the hole plate on the receiving disc can be more conveniently accessed.

[0017] In an improved scheme, an automatic feeding assembly is further included, which comprises a rack and a feeding driving member, the rack is arranged adjacent to the centrifugal rotating table and is provided with guide grooves in which a plurality of target pieces can be sequentially placed, the guide grooves are provided with outlets, and the feeding driving member is used to push the target pieces in the guide grooves to enter the receiving disc from the outlets, so that the operator only needs to place the target pieces into the guide grooves, and the target pieces in the guide grooves can be automatically transferred to the receiving disc by the feeding driving member.

[0018] In an improved scheme, the centrifugal rotating table is cylindrical, the guide grooves are arranged in the radial direction of the centrifugal rotating table, and the outlets of the guide grooves face away from the side of the receiving disc in the horizontal state and away from the centrifugal rotating table, the feeding driving member comprises a synchronous belt, a push block and a feeding motor, the long side direction of the synchronous belt is parallel to the guide grooves, one end of the push block is connected to the synchronous belt and the other end extends to the guide grooves, and the feeding motor is used to drive the synchronous belt to make the push block reciprocate in the direction parallel to the guide grooves, so that the structure is simple and the operation is efficient.

The spring is located inside the pressure cylinder. One end of the spring is connected to the pressure cylinder, and the other end is connected to the upper end of the pressure rod and is used to apply a downward pushing force to the pressure rod. The pressure plate is positioned towards the receiving plate. When the lifting drive causes the lifting frame to descend so that the waste liquid collection hood is lower than the centrifugal turntable, the pressure plate presses against the upper side of the receiving plate to keep the receiving plate horizontal. Thus, when storing or retrieving the perforated plate on the receiving plate, the receiving plate can be kept horizontal due to the action of the pressure plate, making operation more convenient and effectively improving the storage and transfer efficiency of the perforated plate.

[0038] When the centrifugal motor 2 drives the centrifugal turntable 1 to rotate, the lower end of the swing rod 6 is away from the centrifugal turntable 1 due to the centrifugal force of the counterweight pendulum 61, at this time, the upper end of the swing rod 6 drives the receiving disc 4 away from the side of the centrifugal turntable 1 to move along the direction of downward and close to the centrifugal turntable 1 through the connecting rod 5, so that the receiving disc 4 is rotated to a vertical state.

[0039] In the above scheme, the resting area 4a of the receiving disc 4 is used for placing and fixing the target object taking the hole plate as an example, when the centrifugal turntable 1 is in a stationary state, the receiving disc 4 is in a horizontal state, so the hole plate can be placed horizontally into the resting area 4a, avoiding the problem of cross contamination caused by the hole plate being placed vertically; when it is necessary to clean the hole plate, the centrifugal motor 2 drives the centrifugal turntable 1 to rotate, the centrifugal turntable 1 drives the receiving disc 4 to rotate, and the lower end of the swing rod 6 is away from the centrifugal turntable 1 due to the centrifugal force of the counterweight pendulum 61, so the upper end of the swing rod 6 drives the receiving disc 4 away from the side of the centrifugal turntable 1 to move along the direction of downward and close to the centrifugal turntable 1 through the connecting rod 5, so that the receiving disc 4 and the hole plate are gradually rotated to a vertical state, at this time, due to the existence of centrifugal force, the liquid in the hole of the hole plate will be directly thrown out without cross contamination, the rotation speed of the centrifugal motor 2 corresponds to the degree of spin-drying cleaning of the hole plate, which is efficient and stable in cleaning effect.
