Description

Technical Field

[0001] This utility model relates to the field of purification column equipment technology, specifically a novel OLED material purification column equipment. Background Technology

[0002] In the field of organic light-emitting diode (OLED) display technology, the purity of OLED materials plays a decisive role in the luminous efficiency, color purity, and lifespan of the device.

[0003] Novel OLED material purification column equipment typically consists of a precision separation column, an intelligent temperature control system, a pressure regulating device, a solvent circulation module, and an online detection system. The separation column employs special packing materials and column tube design to improve separation efficiency and selectivity; the intelligent temperature control system precisely controls the temperature during the purification process to prevent degradation of heat-sensitive materials; the pressure regulating device optimizes the separation effect by dynamically adjusting the pressure inside the column; the solvent circulation module enables solvent recovery and reuse, reducing production costs and environmental pollution; and the online detection system uses a spectrometer to monitor the purity of the effluent in real time.

[0004] However, in actual use, traditional equipment can only process a single sample column at a time. To complete multiple batches of purification, the sample column needs to be changed manually frequently, and each column change takes 5-10 minutes. Especially in laboratory scenarios with multiple sample requirements, the efficiency is extremely low. In the case of a sample column switching structure without power drive, relying on manual rotation or handling can easily lead to eluent leakage or sample contamination. Moreover, the positioning accuracy is insufficient, which affects the repeatability of column passing. In view of this, we propose a new type of OLED material purification column passing device. Utility Model Content

[0005] The purpose of this invention is to provide a novel column purification device for OLED materials to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel column chromatography device for purifying OLED materials includes a mounting frame, a sample column disposed on the outside of the mounting frame, a stopper being snapped onto the sample column, and an adjustment assembly disposed on the mounting frame, the adjustment assembly comprising:

[0008] The motor is fixedly mounted on the mounting bracket, a cam is fixedly mounted on the output end of the motor, an adjusting column is fixedly mounted on the cam, and a support column is fixedly mounted on the mounting bracket.

[0009] A disc is rotatably mounted on the support column, a petal bracket is fixedly mounted on the disc, a connector is fixedly mounted on the petal bracket, and one end of an installation rod is fixedly mounted at the center of the disc.

[0010] A circular plate is fixedly installed at the other end of the mounting rod. The circular plate has a placement hole, and the mounting rod has a placement groove. A conveying pipe is snapped into place below the connector.

[0011] In a further embodiment, the petal holder, connector, and placement hole are provided in multiple sets.

[0012] In a further embodiment, the sample column is placed on the petal holder through the placement hole, and the bottom of the sample column is connected to one end of the connector.

[0013] In a further embodiment, a funnel is placed in the placement groove on the mounting rod, and the adjusting column is positioned between multiple sets of petal supports.

[0014] In a further embodiment, the mounting rod is provided with an auxiliary component, which includes a ring. The ring is fixedly mounted on the mounting rod, and a clamping arm is fixedly mounted on the ring. A circular groove is provided on the clamping arm, and one end of a spring is fixedly mounted inside the clamping arm. A rubber head is fixedly mounted on the spring.

[0015] In a further embodiment, multiple sets of clamping arms, circular grooves, springs, and rubber heads are provided.

[0016] In a further embodiment, the spring is disposed inside the circular groove, the rubber head slides inside the circular groove, the sample column passes through the clamping arm, and the rubber head is attached to the sample column.

[0017] Compared with the prior art, this utility model provides a novel column purification device for OLED materials, which has the following beneficial effects:

[0018] 1. This novel OLED material purification column chromatography device, designed to meet the rapid purification needs of multiple batches of samples in the laboratory, incorporates an adjustment component. This component, in conjunction with a motor-driven cam, rotates the petal holder around the support column via the adjustment column, causing the disc to synchronously rotate the sample column. This facilitates switching between different sample column chromatography positions. The design of the petal holder and connector allows for automatic docking with the delivery tube when the sample column rotates to the designated position, ensuring precise delivery of the eluent. The placement holes on the disc correspond one-to-one with the petal holders, ensuring the sample column is vertically fixed. Multiple sets of petal holders can simultaneously carry multiple sample columns. Through the intermittent movement of the cam, continuous multi-position column chromatography is achieved, significantly improving efficiency compared to traditional single-column manual operation.

[0019] 2. This novel OLED material purification column equipment incorporates an auxiliary component to prevent eluent leakage. This component, in conjunction with multiple sets of clamping arms on a circular ring, uses springs to elastically hold the sample column. The rubber head adheres to the column surface, forming a flexible, circumferential fixation that can accommodate sample columns of different outer diameters. This avoids damage to the glass column caused by rigid clamping. The preload of the springs automatically compensates for sample column installation errors, ensuring a tight fit between the connector and the bottom of the sample column, thus preventing eluent leakage.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A novel column chromatography device for purifying OLED materials includes a mounting frame 1, a sample column 2 disposed on the outside of the mounting frame 1, and a plug 3 snapped onto the sample column 2.

[0033] In one embodiment of this utility model, an adjustment component 4 is provided on the mounting frame 1. The adjustment component 4 includes a motor 41. The motor 41 is fixedly mounted on the mounting frame 1. A cam 42 is fixedly mounted on the output end of the motor 41. An adjustment column 43 is fixedly mounted on the cam 42. A support column 44 is fixedly mounted on the mounting frame 1. A disc 45 is rotatably mounted on the support column 44. A petal holder 46 is fixedly mounted on the disc 45. A connector 47 is fixedly mounted on the petal holder 46. One end of a mounting rod 48 is fixedly mounted at the center of the disc 45. A circular plate 49 is fixedly installed at the other end of the mounting rod 48. A placement hole 410 is provided on the circular plate 49. A placement groove 411 is provided on the mounting rod 48. A delivery pipe 413 is snapped into place below the connector 47. Multiple sets of petal holders 46, connectors 47 and placement holes 410 are provided. The sample column 2 passes through the placement hole 410 and is placed on the petal holder 46. The bottom of the sample column 2 is connected to one end of the connector 47. A funnel 412 is placed in the placement groove 411 on the mounting rod 48. An adjusting column 43 is provided between multiple sets of petal holders 46.

[0034] In this embodiment, after installing multiple sample columns 2, the motor 41 in the adjustment assembly 4 is started. The output of the motor 41 drives the cam 42 to rotate, and the adjustment column 43 fixed on the cam 42 moves accordingly. The adjustment column 43 pushes the petal holder 46 to rotate around the support column 44, thereby driving the disc 45, the mounting rod 48, the disc 49, and the sample column 2 to rotate synchronously. Due to the special design of the petal holder 46 and the connector 47, when the sample column 2 rotates to the designated position, the delivery tube 413 is connected to the connector 47. At the same time, the placement holes 410 on the disc 49 correspond one-to-one with the petal holder 46, ensuring that the sample column 2 always remains vertically fixed. Multiple sets of petal holders 46 can be used simultaneously. The device carries multiple sample columns 2. Through the intermittent movement of the cam 42, continuous column passing at multiple stations is achieved. When the sample column 2 rotates to the station that connects with the delivery tube 413, the eluent flows into the sample column 2 through the funnel 412. During the process of the eluent flowing through the sample column 2, the OLED material is purified. When one sample column 2 has completed purification, the motor 41 is restarted, the cam 42 continues to rotate, and the adjusting column 43 pushes the next sample column 2 to rotate to the designated station. The above eluent delivery and purification process is repeated. After all sample columns 2 have completed purification, the motor 41 is turned off, the device stops running, the sample columns 2 and the funnel 412 are removed, the device is cleaned, and preparations are made for the next experiment.

[0035] In one embodiment of this utility model, an auxiliary component 5 is provided on the mounting rod 48. The auxiliary component 5 includes a ring 51. The ring 51 is fixedly installed on the mounting rod 48. A clamping arm 52 is fixedly installed on the ring 51. A circular groove 53 is opened on the clamping arm 52. One end of a spring 54 is fixedly installed inside the clamping arm 52. A rubber head 55 is fixedly installed on the spring 54. Multiple sets of clamping arms 52, circular grooves 53, springs 54 and rubber heads 55 are provided. The spring 54 is located inside the circular groove 53. The rubber head 55 slides inside the circular groove 53. The sample column 2 passes through the clamping arm 52 and the rubber head 55 is attached to the sample column 2.

[0036] In this embodiment, the OLED material sample to be purified is loaded into the sample column 2, the stopper 3 is placed on it, and then the sample column 2 is passed through the placement hole 410 on the circular plate 49 and placed on the petal holder 46. At this time, the bottom of the sample column 2 is connected to one end of the connector 47, completing the initial installation. At the same time, the auxiliary component 5 plays a role. Multiple sets of clamping arms 52 on the ring 51 surround the outside of the sample column 2, and the spring 54 pushes the rubber head 55 to slide, so that the rubber head 55 fits tightly against the surface of the sample column 2. The elastic clamping of the spring 54 can adapt to sample columns 2 with different outer diameters, avoiding damage to the glass column caused by rigid clamping, and automatically compensating for errors during the installation of the sample column 2.

[0037] All electrical components appearing in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the motor 41. All standard parts used in this application can be purchased from the market.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
