Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automation equipment, and in particular relates to a fully automatic sample box picking and placing device for a pneumatic sample delivery system. Background Technology
[0002] In existing technologies, sample box handling typically involves the following methods and equipment: 1. Manual operation: This is the most traditional method. Operators directly place or remove sample boxes from the pneumatic sample delivery system by hand. This method is simple but inefficient and prone to human error, failing to meet the efficiency and accuracy requirements of modern production. 2. Semi-automatic auxiliary equipment: To reduce manpower and improve efficiency, some systems employ semi-automatic auxiliary equipment, such as slide rails and rollers, to help operators handle sample boxes more easily. While these devices reduce labor intensity, they still require manual intervention and do not achieve true automation. 3. Industrial robots: With the development of automation technology, industrial robots have been introduced into the sample box handling process. Robots can accurately and quickly complete sample box handling according to preset programs. However, the cost of using industrial robots is high, and they require significant space for installation and operation, making them uneconomical for small laboratories or production lines. 4. Dedicated automated devices: There are also specially designed automated devices on the market for sample box handling. These devices are typically tightly integrated with pneumatic sample delivery systems, enabling automatic loading and unloading of sample boxes. While these systems improve automation, they are often complex in design, costly, and may take a long time to customize and integrate.
[0003] In summary, existing sample box handling methods suffer from problems such as high cost, large space occupation, and insufficient automation. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the present invention aims to provide an improved fully automatic sample box picking and placing device to solve these problems.
[0005] The fully automatic sample box loading and unloading device provided by this utility model includes: a guide rod cylinder, parallel grippers, a vacuum suction cup, a rodless cylinder, a standard cylinder, a frame, a safety light curtain, a conveyor line, and a sample box fixing base. The vacuum suction cup is fixed at the root of the parallel grippers in the middle, and the parallel grippers are mounted on the guide rod cylinder. The vacuum suction cup can be tightly attached to the bottom of the sample box. Both the parallel grippers and the guide rod cylinder are mounted on the rodless cylinder. When the vacuum generator is activated, the vacuum suction cup picks up the sample box, the guide rod cylinder pulls the sample box out to a position sufficient for the grippers to hold it, and the parallel grippers close to hold the sample box. The guide rod cylinder is controlled by a three-position center-sealed solenoid valve.
[0006] The rodless cylinder is mounted at an angle on the frame, with one end directly above the sampling port of the pneumatic equipment. The sample box holder is mounted on the conveyor line, with one end of the conveyor line mounted on the frame directly below the other end of the rodless cylinder. The guide rod cylinder and the rodless cylinder work together. When the guide rod cylinder retracts, it completely detaches the sample box from the pneumatic equipment. The rodless cylinder then moves the entire assembly to the other end, releasing the sample box into the sample box holder on the conveyor line. The conveyor line then transports the sample box to the next process.
[0007] The standard cylinder is fixed on the frame and is used to control the sampling port switch. The piston rod of the standard cylinder is connected and fixed to the pneumatic switch handle of the pneumatic sample delivery equipment. The standard cylinder extends to push the pneumatic switch handle to open the air delivery pipe. The standard cylinder is controlled by a three-position central leakage solenoid valve. When the solenoid valve is in the depressurization position, the operator can manually push and pull the pneumatic switch handle for manual operation.
[0008] In addition, a safety light curtain is erected in front of the fully automated sample box handling equipment to ensure the safety of operators.
[0009] The fully automatic sample box picking and placing device of this utility model can realize displacement in both horizontal and vertical directions by installing the rodless cylinder at a certain angle to the horizontal plane, thus realizing the precise movement and full automation of sample box picking and placing, and increasing the upstream and downstream linkage distance of the pneumatic sample delivery equipment. The standard cylinder is controlled by a three-position central leakage solenoid valve, which supports the switching between manual and automatic modes to meet the needs of different working conditions, and also has the advantages of low cost and small space occupation.

[0012] To further illustrate this utility model, the specific embodiments of the sampling rack of this utility model are described in detail below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are merely illustrative examples of this utility model and are not intended to limit it in any way.
[0013] The fully automatic sample box loading and unloading device for the pneumatic sample delivery system includes a guide rod cylinder (1), a parallel gripper (2), a vacuum suction cup (3), a rodless cylinder (5), a standard cylinder (6), a frame (9), a safety light curtain (10), a conveyor line (11), and a sample box fixing seat (12). The vacuum suction cup (3) is fixed at the root of the middle of the parallel gripper (2), which is mounted on the guide rod cylinder (1). The vacuum suction cup (3) can be pressed against the bottom of the sample box (4). The parallel gripper (2) and the guide rod cylinder (1) are both mounted on the rodless cylinder (5). The rodless cylinder (5) is mounted at an angle on the frame (9). One end of the rodless cylinder (5) is directly above the sampling port of the pneumatic equipment. The sample box fixing seat (12) is mounted on the conveyor line (11), and one end of the conveyor line (11) is mounted on the frame (9) directly below the other end of the rodless cylinder (5).
[0014] When the rodless cylinder (5) moves to one end of the conveyor line (11), the sample box (4) on the parallel gripper (2) aligns with the sample box fixing seat (12). The guide rod cylinder (1) extends out of the sample box (4) and enters the sample box fixing seat (12). The vacuum suction cup (3) releases from the parallel gripper (2), and the guide rod cylinder (1) retracts into the conveyor line (11), thus conveying the sample box (4) to the next station. Then, the empty sample box is returned. The above actions are reversed to put the empty sample box (4) back into the pneumatic sample delivery equipment. The guide rod cylinder (1) is controlled by a three-position center-sealed solenoid valve.
[0015] The standard cylinder (6) is fixed on the frame (9), and the piston rod of the cylinder is connected and fixed to the pneumatic switch handle (7); the standard cylinder (6) is controlled by a three-position central leakage solenoid valve, which allows manual operation when the solenoid valve is depressurized.
[0016] Safety light curtain (10) is erected in front of the fully automatic sample box handling equipment. The equipment stops when staff enters to prevent injury.
[0017] When in operation, the three-position venting solenoid valve is in the venting state, and there is no air pressure in the standard cylinder. At this time, the operator can easily push the switch lever to manually pick up and place samples.
[0018] During automatic sampling, the standard cylinder extends to push the pull rod to open the sampling port of the pneumatic device. With the parallel grippers open, the guide rod cylinder extends, and the vacuum suction cup is aligned with the bottom of the sample box, presses it, and then opens the vacuum to suction it. The guide rod cylinder, controlled by a three-position centrally sealed solenoid valve, pulls the sample box out to a position where the grippers can hold it. The parallel grippers close and hold the sample box. The guide rod cylinder continues to retract, completely detaching the sample box from the pneumatic device. The rodless cylinder moves the entire device to the other end. The above actions are repeated in reverse to release the sample box into the sample box holder on the conveyor line. The conveyor line then transports the sample box to the next process. The above describes the sample box removal action. The sample box placement action can also be performed in reverse.
[0019] The above description of this utility model is merely a specific embodiment of the utility model and is not intended to limit the utility model in any way. Any equivalent changes and modifications made to it based on the spirit of this utility model shall be within the scope of the technical protection scheme of this utility model.
