Therefore, according to another aspect of the utility model, a spotting device is also provided. The feeding device and the spotting device of the utility model embodiments will be described in detail below in combination with the drawings.

[0026] As Figures 1-2As shown, the loading device can include a main body 100, a tray assembly 200, a fixing assembly 300, and a releasing assembly 400.

[0027] The main body 100 can have various structures, such as a frame, a support, or a base.

[0028] The tray assembly 200 can be used to place materials 700 thereon. The materials 700 include, but are not limited to, spotting liquid, spotting plate, or spotting needle. In an embodiment where the materials 700 include spotting liquid, the spotting liquid can be contained in a bulk bottle. In this way, the tray assembly 200 can be used to place bulk bottles containing spotting liquid thereon. The number of bulk bottles can be arbitrary. In some embodiments, 200 bulk bottles can be placed on the tray assembly 200. The 200 bulk bottles can be arranged in a 20x10 array.

[0029] The tray assembly 200 is movably connected to the main body 100 between a loading station and a feeding station. The tray assembly 200 can move in a horizontal direction, a vertical direction, or any other suitable direction between the loading station and the feeding station. The loading station is used to manually or automatically carry the materials 700 to the tray assembly 200 at this location, thereby completing the loading of the materials 700. It can also be understood that the relevant personnel manually or through any suitable carrying device such as a mechanical hand places the materials 700 on the tray assembly 200 at the loading station. Then, the tray assembly 200 can be moved to the feeding station. The feeding station is used to automatically or manually carry the materials 700 on the tray assembly 200 to a designated working position, thereby completing the feeding of the materials 700. It can also be understood that the relevant personnel can manually or through any suitable carrying device such as a mechanical hand take out the materials 700 on the tray assembly 200 at the feeding station, which can be carried to the next process (i.e., the designated working position). In an embodiment where the materials 700 include spotting liquid, the relevant personnel can take out the spotting liquid on the tray assembly 200 at the feeding station through a spotting device, which can be used for subsequent spotting operations.

[0030] Exemplarily, when the tray assembly 200 is at the feeding station, it can be inside the main body 100. In this way, the main body 100 can play a protective role to prevent the tray assembly 200 from being affected by factors of the main body 100. When the tray assembly 200 is at the loading station, it can be outside the main body 100. In this way, the tray assembly 200 can not be limited by the main body 100, thereby facilitating the loading of the materials 700. Exemplarily, in an embodiment where the main body 100 includes a frame, the frame can be provided with an opening. The tray assembly 200 can extend outside the frame through the opening to move to the loading station, and can enter the frame through the opening to move to the feeding station.

[0031] Exemplarily, the tray assembly 200 can be provided with a positioning groove 210. The positioning groove 210 can be used to place the tray 600. That is, the tray 600 can be at least partially embedded in the positioning groove 210. The tray 600 can be the material 700 itself, or the material 700 can be placed on the tray 600. The positioning groove 210 can play a role in positioning the tray 600 to ensure that the position of the tray 600 relative to the tray assembly 200 is relatively fixed. Moreover, the positioning groove 210 can also play a role in limiting the tray 600 from moving during the movement of the tray assembly 200 between the feeding station and the feeding station. In the embodiment in which the material 700 is placed on the tray 600, the material 700 can be placed on the tray 600 of the tray assembly 200 located at the feeding station, or the material 700 can be pre-placed on the tray 600 and then placed together on the positioning groove 210 of the tray assembly 200; similarly, the material 700 can be taken out from the tray 600 of the tray assembly 200 located at the feeding station, or the material 700 and the tray 600 can be taken out together from the positioning groove 210 of the tray assembly 200. The positioning groove 210 can play a role in positioning the tray 600 to ensure that the position of the tray 600 relative to the tray assembly 200 is relatively accurate. Moreover, the positioning groove 210 can also play a role in limiting the tray 600 from moving during the movement of the tray assembly 200 between the feeding station and the feeding station. In the embodiment in which the material 700 includes a crude bottle, the tray 600 can be provided with a plug hole 610. Each crude bottle can be inserted into the plug hole 610.

[0032] The fixing assembly 300 can be provided on the main body 100. The fixing assembly 300 can be used to fix the tray assembly 200 located at the feeding station. The fixing assembly 300 includes but is not limited to a magnetic assembly, a suction cup assembly, or a clamping assembly.

[0033] The releasing assembly 400 can be provided on the main body 100. The releasing assembly 400 can be used to drive the tray assembly 200 located at the feeding station to move towards the feeding station. Exemplarily, the releasing assembly 400 can drive the tray assembly 200 to move directly to the feeding station, or can drive the tray assembly 200 to move between the feeding station and the feeding station. The releasing assembly 400 includes but is not limited to a magnetic assembly, a suction cup assembly, a pushing assembly, or a pulling assembly.

[0034] In actual application, the material 700 can be placed on the tray assembly 200 at the feeding station. Then, the tray assembly 200 can be moved towards the feeding station. When the tray assembly 200 moves to the feeding station, the fixing assembly 300 can fix the tray assembly 200. When the feeding of the material 700 is completed, the releasing assembly 400 can drive the tray assembly 200 to move towards the feeding station, so that the tray assembly 200 can be released from the fixing of the fixing assembly 300. In the embodiment in which the tray assembly 200 is located in the main body 100 at the feeding station, the releasing assembly 400 can drive the tray assembly 200 to at least partially extend out of the main body 100, so that the relevant personnel can drive the tray assembly 200 to continue to move by pushing or pulling, etc. In some embodiments, the tray assembly 200 can be provided with a handle 220. The relevant personnel can drive the tray assembly 200 to move by the handle 220.

[0035] In summary, the feeding device provided by the embodiment of the present application can fix the tray assembly 200 by the fixing assembly 300 when the tray assembly 200 moves to the feeding station, so as to accurately position the tray assembly 200. In this way, the tray assembly 200 can be at the expected position, so as to smoothly feed. Therefore, the feeding device has high reliability, and the user has good experience.

[0036] Exemplarily, the fixing assembly 300 can include an electromagnet assembly. The electromagnet assembly can be used to adsorb the tray assembly 200 at the feeding station. Specifically, the electromagnet assembly can be used to adsorb the tray assembly 200 at the feeding station when the electromagnet assembly is powered. Exemplarily, when the tray assembly 200 moves to the feeding station, the electromagnet assembly can be continuously powered, or the electromagnet assembly can be powered only for a first predetermined time (for example, 1 second, 2 seconds or other time). After the first predetermined time, the electromagnet assembly no longer consumes energy due to power loss, and will not generate heat again, so as to avoid burning the coil and weakening the magnetic force, thereby improving the performance and service life, and avoiding safety risks. The electromagnet assembly can cancel the adsorption of the tray assembly 200 at the feeding station when the electromagnet assembly is powered off. In this way, the structure of the tray assembly 200 does not need to be changed, so that the existing structure can be used. Moreover, the electromagnet assembly can be convenient to install and control.

[0037] Exemplarily, the electromagnet assembly can be used to adsorb the tray assembly 200 at the feeding station when the electromagnet assembly is powered. When the electromagnet assembly is powered off, the electromagnet assembly cancels the adsorption force of the tray assembly 200, and the releasing assembly 400 can be used to drive the tray assembly 200 at the feeding station to move towards the feeding station. In this way, the energy consumption of the releasing assembly 400 to drive the tray assembly 200 is small.

[0038] Exemplarily, the fixed assembly 300 can be located at one side of the tray assembly 200 along the moving direction thereof. Compared with being located at other positions (for example, at a side perpendicular to the moving direction), the tray assembly 200 can abut against the fixed assembly 300 when moving to the feeding station. In this way, the fixed assembly 300 can not only be used for fixing the tray assembly 200, but also can limit the position of the tray assembly 200.

[0039] Exemplarily, the releasing assembly 400 can include a push-pull electromagnet assembly. The push-pull electromagnet assembly can be used for pushing the tray assembly 200 located at the feeding station to move towards the feeding station. In this way, the structure of the tray assembly 200 does not need to be changed, so that the existing structure can be used. Moreover, the push-pull electromagnet assembly can be convenient to install and control.

[0040] Exemplarily, the push-pull electromagnet assembly can include a housing 410 and an electromagnet 420. The housing 410 can be arranged on the main body 100. The electromagnet 420 is movably connected to the housing 410, so that the tray assembly 200 located at the feeding station can be pushed to move towards the feeding station. Specifically, the electromagnet 420 can move on the housing 410 by being powered and de-energized, so that the tray assembly 200 located at the feeding station can be pushed to move towards the feeding station. In this way, the structure of the push-pull electromagnet assembly is relatively simple, which is convenient to manufacture. Exemplarily, after the tray assembly 200 finishes feeding, the electromagnet 420 can be powered for a second predetermined time length (for example, 1 second, 2 seconds or other time length), so that the tray assembly 200 located at the feeding station can be pushed to move towards the feeding station. After the second predetermined time length, the electromagnet 420 can move to the original position due to de-energization. In this way, the electromagnet 420 does not consume energy and does not generate heat due to de-energization, so that the coil can be prevented from burning out, the magnetic force can be inhibited from weakening, and thus the performance and service life can be improved, and the safety risk can be avoided.

[0041] Exemplarily, the feeding device can further include a button and a controller. The button can be arranged on the main body 100. The controller can be electrically connected to the fixed assembly 300 and the releasing assembly 400. The controller can be built by using electronic elements such as timers, comparators, registers, digital logic circuits, or realized by using processor chips such as single-chip microcomputers, microprocessors, programmable logic controllers (PLC), digital signal processors (DSP), field programmable gate arrays (FPGA), programmable logic arrays (PLA), application-specific integrated circuits (ASIC) and peripheral circuits thereof. When the relevant personnel triggers the button, the controller can be used for controlling the fixed assembly 300 to cancel fixing the tray assembly 200 located at the feeding station, and controlling the releasing assembly 400 to drive the tray assembly 200 located at the feeding station to move towards the feeding station. In this way, the feeding device has a relatively high degree of automation, so that the production efficiency can be improved.

[0042] Exemplarily, the feeding device can further include a first sliding rail 510 and a second sliding rail 520. The first sliding rail 510 and the second sliding rail 520 can extend along the sliding direction of the tray assembly 200 respectively. The first sliding rail 510 can be arranged on the main body 100. The second sliding rail 520 can be slidably connected to the first sliding rail 510. The tray assembly 200 can be slidably connected to the second sliding rail 520. The first sliding rail 510 and the second sliding rail 520 can guide and limit the tray assembly 200, so as to improve the sliding accuracy of the tray assembly 200. Moreover, since the second sliding rail 520 can slide relative to the first sliding rail 510 and the tray assembly 200 respectively, the sliding distance of the tray assembly 200 is larger. Moreover, the tray assembly 200 is more easily slid out of the main body 100.
