Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated equipment for biochemical experiments, and in particular to a biological sample heating unit. Background Technology
[0002] In biological experiments, at each stage of handling biological samples, processes such as cooling and heating of the sample tubes (centrifuge tubes) are required to better preserve or separate the components in the sample.
[0003] For the heating process, the existing method is to arrange centrifuge tubes on a heating plate and heat them by passing electricity through the heating plate. The heating process is controlled by a control unit to make the centrifuge tubes quickly reach the predetermined temperature and maintain it.
[0004] However, when replacing centrifuge tubes after heating is complete, the power must be turned off first, the heating plate removed, the centrifuge tube taken out, a new centrifuge tube to be heated placed in it, and the heating plate covered again before heating can be restarted. Sometimes, specific treatment is required when removing the centrifuge tubes, which causes the heat to dissipate by the time the heating plate is powered on again, increasing the time of the second heating process and affecting the progress and accuracy of the experiment. Utility Model Content

[0042] The specific embodiments of the biological sample heating unit of this utility model are described in detail below with reference to the accompanying drawings.
[0043] See appendix Figure 1 The biological sample heating unit mainly includes a heating section 1, a backup heating section 2, and a spare parts section 3, which are arranged close to each other. The heating section 1 is used to heat the sample in the centrifuge tube 4, the backup heating section 2 is used to assist the heating section 1 in heating, and the spare parts section 3 is used to dispense the centrifuge tube 4.
[0044] See appendix Figures 2 to 5 The heating unit 1 includes a base 5, a sample card plate 6, a heating plate 7, and a hot pressing plate 8. The sample card plate 6 is fitted into a slot on the sample base 5. The sample base 5 is provided with an insertion hole 9. A sample tube is inserted into the sample card plate 6. The heating plate 7 is arranged above the sample card plate 6, and the hot pressing plate 8 is arranged above the heating plate 7.
[0045] The base 5, sample card plate 6, heating plate 7 and hot press plate 8 are all provided with card holes at both ends. The above components are stacked by inserting pins 10 into the card holes. The area of sample card plate 6, heating plate 7 and hot press plate 8 is equivalent to the area of base 5.
[0046] The sample card plates 6 are arranged in two rows side by side on the base 5. Each sample card plate 6 has a card hole at both ends. The base 5, sample card plates 6, heating plate 7 and hot pressing plate 8 each have two corresponding card holes on each side. The pins 10 are set in correspondence with the card holes.
[0047] See appendix Figures 6 to 8 The backup heating unit 2 includes a bracket 11, a backup heating plate 12 and a backup hot press plate 13. The backup heating plate 12 is mounted on the bracket 11 through a heat insulation plate 14, and the backup hot press plate 13 is located above the backup heating plate 12. The backup heating plate 12 is the same as the heating plate 7 and can be substituted.
[0048] The spare hot press plate 13 can be interchanged with the hot press plate 8, or only one can be used. When the hot press plate 8 is removed, the hot press plate is placed on the standby heating section 2 for heating. After the sample tube is placed in the heating section, the hot press plate is removed from the standby heating section and moved to the heating section. In addition to heat preservation, the hot press plate 8 is also used to balance the sample tube on the sample holder 6.
[0049] The bracket 11, the spare heating plate 12 and the spare hot pressing plate 13 are all provided with locking holes at both ends. The above components are stacked by inserting the pin 10 into the locking holes. The area of the spare heating plate 12 and the spare hot pressing plate 13 is equivalent to the area of the bracket 11.
[0050] Similarly, when the locking pin 10 of the heating part 1 is fixed by double locking pins at both ends, the locking pins and pins 10 on both sides of the heat preparation part 2 correspond to the locking pins and pins 10 on both sides of the heating part 1.
[0051] Each sample tray 6 has four insertion holes 9, and one sample tube (centrifuge tube 4) is inserted into each insertion hole 9. The insertion holes 9 on the base 5 of the heating unit 1 are used for inserting the centrifuge tube 4.
[0052] The hot press plate 8 and the spare hot press plate 13 can be arranged side by side, with clamping ports 15 on both sides for loading and clamping by the robot arm, which facilitates robot arm operation.
[0053] See appendix Figure 1 , 5 A spare part 3 is also provided on one side of the heating part 1, including a positioning seat 16 and a spare card plate 17. The spare card plate 17 is fixed in the slot of the positioning seat 16. The spare card plate 17 is used interchangeably with the sample card plate 6. Similarly, the positioning seat 16 also has a hole 9 for inserting centrifuge tube 4.
[0054] A vibration unit is installed below the heating unit 1 and the spare part 3. While the heating unit 1 heats the sample tube, it also vibrates the sample tube. At the same time, it also vibrates the unheated sample in the spare part to mix the solution in the sample tube.
[0055] The heating plate 7 and the standby heating plate 12 of the heating unit 1 and the standby heating unit 2 include a base plate 18, an upper plate 19, and a heating film 20. There are two heating films 20, which are disposed between the base plate 18 and the upper plate 19. A temperature sensor 21 is also disposed between the base plate 18 and the upper plate 19. Both the heating film 20 and the temperature sensor 21 are connected to the control unit.
[0056] This patent can be directly applied to automated scenarios. The heating unit 1, standby heating unit 2, and spare parts unit 3 are installed on an automated workbench. A robotic arm is positioned on the workbench. When heating the sample tube, the robotic arm removes the pressure plate and heating plate 7 of the heating unit 1 and places the sample holder 6 onto the base 5. Simultaneously, the spare heating plate 12 of the standby heating unit 2 heats and holds the spare pressure plate 13. The robotic arm places the heating plate 7 of the heating unit 1 onto the sample holder 6, then removes the spare pressure plate from the standby heating unit 2 and places it onto the heating plate 7 of the heating unit 1. The pressure plate 8 of the heating unit 1 is then placed onto the standby heating unit 2 for heating. The spare parts unit 3 is used to hold the sample holder 6, whether it is to be heated or has been heated, for use in other experimental procedures or for transfer from other locations.
[0057] During the heating process, the standby heating unit 2 keeps the hot plate 8 in standby mode. When the sample clamping plate 6 is replaced in the heating unit 1, the hot plate is replaced, so that when the heating unit 1 heats the sample, there is always a hot plate to keep the temperature maintained.
[0058] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
