Description

Technical Field

[0001] The utility model relates to an online full-automatic sample feeding system for pre-treatment of plated parts, belonging to the technical field of sample detection. Background Art

[0002] Traditional testing of plating pretreatment bath liquid usually adopts a single-point sampling method, which cannot fully reflect the status of the entire bath liquid and easily leads to one-sided test results. In addition, single-point sampling cannot monitor the changes in components at different locations in the bath liquid, which is not conducive to timely detection and treatment of local abnormalities. Pretreatment bath liquid testing mainly relies on manual sampling and laboratory titration, which is inefficient, time-consuming, and easily affected by human errors. Traditional detection methods cannot achieve real-time monitoring,

[0003] To address this, we have developed a multi-point sampling system for pre-treatment of plated parts, which can achieve multi-point sampling. After achieving multi-point sampling, the collected samples need to be transmitted to the detector. Therefore, it is necessary to develop a corresponding online fully automatic sampling system for pre-treatment of plated parts. Utility Model Content

[0004] The utility model aims to provide an online fully automatic sample feeding system for pre-treatment of plated parts.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An online fully automatic sampling system for pre-treatment of plated parts comprises a syringe pump bracket and a plurality of syringe pumps mounted on the syringe pump bracket; a multi-way valve is arranged at the sampling port of the syringe pump; and a sampling unit is also included; the multi-way valve can be connected to the syringe pump, the sampling unit and a detector.

[0007] A further improvement of this technical solution is that the multi-way valve is a rotary multi-way valve.

[0008] A further improvement of the technical solution of the present utility model is that the system also includes a central controller that plays a control role.

[0009] Due to the adoption of the above technical solution, the technical effects achieved by the utility model are as follows:

[0010] The sampling system of the utility model can inject samples collected by multiple sampling units of the multi-point sampling system into the detector, thereby realizing fully automated operation from sampling to analysis, improving work efficiency, reducing human errors, and ensuring the accuracy of analysis results and the stability of the production process.

[0011] The utility model provides a practical rotary multi-way valve, which can be easily controlled and can be perfectly matched with a multi-point sampling system. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] The utility model is an online fully automatic sampling system for plating pre-treatment, which is used for sampling bath liquid in plating pre-treatment. The sampling system cooperates with a sampling system and a detector to realize sampling, sampling and detection of bath liquid.

[0017] like Figure 1 、 Figure 2 As shown, the system mainly includes a syringe pump bracket 1 and a syringe pump 1 mounted on the syringe pump bracket 1. The syringe pump bracket 1 is used to mount the syringe pump 1. Several syringe pumps 1 are mounted on the syringe pump bracket 1 to process the bath liquid collected by multiple sampling units. Each syringe pump 1 corresponds to a multi-way valve 3, which in turn corresponds to a sampling unit in the sampling system through the multi-way valve 3.

[0018] A multi-way valve 3 is provided at the injection port of the syringe pump 2, and the flow channel of the bath liquid is switched by the multi-way valve 3. The front end of the injection system is a sampling unit, and the rear end is a detector. The multi-way valve 3 can be connected to the syringe pump 2, the sampling unit, and the detector. The sampling unit is responsible for collecting and filtering the bath liquid in the plating pretreatment tank. Then, through the action of the multi-way valve 3, the injection system injects the bath liquid collected by the sampling unit into the detector, where the bath liquid is detected.

[0019] In a specific implementation, preferably, the multi-way valve 3 is a rotary multi-way valve. When changing the channel, the multi-way valve 3 rotates.

[0020] The system also includes a central controller that plays a control role. The central controller is responsible for controlling the operation logic of each unit.

[0021] The fully automatic sampling system is installed on the hot-dip galvanizing production line. After the automatic sampling system selects the sampling point by controlling the multi-way valve, it controls the injection pump to quantitatively take liquid from the sampling unit. At this time, the sample liquid is in the injection pump. Then, the multi-way valve is rotated, and the injection pump injects the sample liquid into the detector at the rear through the multi-way valve. Other reagents are quantitatively added to the detector at the rear in the same way.

[0022] The utility model realizes the fully automated operation from sampling to analysis, improves the work efficiency, reduces the human error, and ensures the accuracy of the analysis result and the stability of the production process.

[0023] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
