Abstract
Description
Technical Field
[0001] This utility model relates to the field of mass loading of gun heads for scientific research instruments, and in particular to a sorting device for mass loading gun heads. Background Technology
[0002] In the field of batch sorting and loading nozzle technology, batch loading instruments for 10ul and 100-200ul nozzles are already quite mature, and can be achieved through two technical means. One is to use an equally spaced sieve device to divide the 10ul and 100-200ul nozzles at equal intervals in the x and y directions. The other is to use a complex CNC system with the help of a motor to complete semi-automatic single-nozzle loading.
[0003] Firstly, CNC machine tools with electric motors are often very expensive, ranging from tens of thousands to hundreds of thousands of yuan, requiring extremely high precision. Secondly, most sorting devices on the market are currently limited to batch loading of 10ul and 100-200ul syringe tips; simple batch loading devices for 1ml syringe tips are almost nonexistent. The key technical challenge in batch loading 1ml syringe tips lies in the fact that the material used to manufacture the 1ml syringe tip boxes is prone to deformation after thinning, leading to tip loss. Secondly, the traditional tooth-counting method cannot perform a secondary equidistant division of the 1ml syringe tips that have already undergone initial sorting. The holes in commercially available 1ml syringe tip boxes are often of varying sizes, or even crisscrossed, making the traditional neat xy-axis division method unsuitable for this practical situation. Utility Model Content

[0030] The present invention will now be further described with reference to the accompanying drawings.
[0031] This utility model embodiment provides a sorting device for batch loading of gun heads, such as... Figures 1 to 3 As shown, the sorting device for batch loading gun heads includes a screening box 100, a pin picker 200, and a pin top plate 300. The pin picker 200 includes a pick-up plate 210 and pick-up plugs 220. The pick-up plate 210 is provided with at least one through hole 211, and there are multiple pick-up plugs 220, all of which are fixed in the through hole 211. The pin top plate 300 includes a main plate 310 and a plug plate 320. The number of plug plates 320 is the same as the number of through holes 211. The plug plates 320 are located at the lower end of the main plate 310. The pick-up plugs 220 are used to pick up gun heads. The size of the plug plate 320 is smaller than the size of the through hole 211, so that the plug plate 320 can extend into the through hole 211 to remove the gun head 400 picked up by the pick-up plug 220 and store it in the screening box 100.
[0032] When the sorting device for batch loading gun heads is not in use, i.e., when the screening box 100 is not yet storing gun heads, the needle pickup 200 can be placed in the screening box 100, and the needle top plate 300 can be placed on the needle pickup 200. In practical applications, one needle pickup 200 and needle top plate 300 can be used with several screening boxes 100.
[0033] In practical use, the handheld needle picker 200 is used to pick up needles through the pick-up plug 220. The pick-up plug 220 can be made of elastic material, with a conical tip and a bottom diameter smaller than that of the nozzle 400. This allows it to penetrate to a certain depth into the nozzle 400. The tip is then squeezed, and the nozzle 400 is fixed in place by the friction between the tip and the inner wall of the nozzle 400. After each pick-up plug 220 has picked up a nozzle, the needle picker 200 is placed above the screening box 100. The insert plate 320 of the needle top plate 300 is inserted into the through hole 211 to remove the nozzle picked up by the pick-up plug 220 into the screening box 100. Since each pick-up plug 220 is evenly arranged on the x-axis and y-axis, the nozzles picked up and placed down are also evenly arranged in the screening box on the x-axis and y-axis, thus quickly realizing the batch packaging of nozzles.
[0034] like Figure 3 As shown, Figure 3 (a) is a structural diagram of the needle pickup 200 when it picks up the nozzle 400, and (b) is a structural diagram of the needle pickup 200 when it does not pick up the nozzle 400.
[0035] In some embodiments, the screening box 100 includes a box body 110 with an opening at the top. At least one partition plate 120 is provided inside the box body 110. At least two grooves 130 are formed inside the box body 110 through the at least one partition plate 120. The grooves 130 are used to store the gun head 400 picked up by the pickup plug 220. The height of the partition plate 120 is lower than the height of the box body 110.
[0036] In this embodiment, as Figure 1 As shown, a groove 130 is formed in the screening box 100 by the partition plate 120 to ensure that the picked-up gun heads 400 can be neatly arranged in the box body 110 without tipping over.
[0037] In some embodiments, such as Figure 2 As shown, the pickup plug 220 includes an inverted cone-shaped plug 221 and a cylindrical connector 222; wherein, the cylindrical connector 222 is fixed in the through hole 211, the lower end of the cylindrical connector 222 is connected to the upper end of the inverted cone-shaped plug 221, and a through hole 223 is provided on the cylindrical connector 222.
[0038] In this embodiment, the inverted cone-shaped plug 221 is inserted into the gun head 400 to fix the gun head 400. The cylindrical connector 222 is connected to the inverted cone-shaped plug 221 and its function is to install the inverted cone-shaped plug 221. When picking up the gun head 400, at least a portion of the cylindrical connector 222 is inserted into the gun head 400. The through hole 223 penetrates through the cross-sectional direction of the cylindrical connector 222, rather than penetrating vertically through the cylindrical connector 222. The insert plate 320 is inserted into the through hole 223 through the through hole 211 to remove the gun head picked up by the pickup plug 220.
[0039] In some embodiments, such as Figure 1 As shown, the pickup plug-in 220 is set to 50-100. The number of pickup plug-ins 220 is determined according to the actual number of gun heads to be picked up in a batch. Currently, 50 and 99 are common. The corresponding number of pickup plug-ins 220 is set according to the pickup requirements of different batches of gun heads.
[0040] In some embodiments, such as Figure 1 As shown, the grooves 130 are set to 9 to 15, for example, they can be as follows: Figure 1 The 12 grooves shown can typically hold 10 1ml pipette tips. Taking the batch loading of 1ml pipette tips as an example, the groove 130 can be a rectangular groove with a width of 7-8mm, a length of 200-240mm, and a depth of 5-6mm, and the spacing between the grooves 130 is 1-2mm.
[0041] For example, the grooves 130 provided inside the box body 110 are 12 rows of rectangular grooves with a width of 7.8mm, a length of 220mm, and a depth of 5.6mm. The groove spacing is 1.45mm or can be adapted to different 1ml box spacings.
[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
