Technical Field

[0001] This utility model relates to the field of experimental equipment, and in particular to a picking and boxing device for sorting gun tips. Background Technology

[0002] A pipette tip (or simply "tip") is a container used with a pipette to measure small amounts of liquid. Due to their convenience, speed, accuracy, and affordability, pipettes are highly favored by biological and chemical laboratories and medical institutions.

[0003] Currently, the price of pre-packaged pipette tips is very expensive, while the quantity of pipette tips used in experiments is large, and pre-packaged tips would increase experimental costs. Therefore, to save costs, users often purchase large quantities of loose pipette tips and manually pack them into boxes for convenient use in experiments. However, manually packing loose pipette tips one by one is time-consuming, increases the experimental cycle, and can easily lead to pipette tip contamination, loss, and waste if not handled properly. Therefore, manufacturers are focusing on research into automated pipette tip packing. Current automated packing processes use a sorting device to sort the pipette tips, then separate the sorted tips to match the dimensions of the box, and finally use a pick-up device to move the tips into the box. This results in a complex and time-consuming sorting process, leading to low efficiency. Utility Model Content

Figures 2A-2C These are schematic diagrams of some structures of the automatic gun tip boxing device from different angles. Figure 2D This is a schematic diagram of the internal structure of the automatic gun tip boxing device.

[0026] As shown in the figure, the automatic boxing device for pipette tips (hereinafter referred to as "automatic boxing device") 100 includes a base 110, a feeding device 120, a feeding trough 130, a feeding device 140, a feeding trough 150, and a conveying device 160. The unloading device 120, feeding trough 130, feeding device 140, unloading trough 150, and conveying device 160 are arranged above the base 110. The unloading device 120 can organize the bulk gun heads entering it, so that the gun heads are arranged neatly and orderly in the unloading device. The feeding trough 130 can be used to hold bulk gun heads. The feeding device 140 can be used to convey the bulk gun heads in the feeding trough 130 to the top of the unloading device. The unloading trough 150 can be used to hold gun heads that have not entered the unloading device. The conveying device 160 can be used to convey the bulk gun heads in the unloading trough 150 that have not entered the unloading device to the feeding trough. The gun heads can be conveyed back to the unloading device through the feeding device 140, thereby realizing the automated sorting of gun heads. In some embodiments, the automatic boxing device 100 may not include the feeding device 140. That is, the feeding trough 130 may be directly set above the unloading device 120, and the gun heads in the feeding trough may be directly poured into the unloading device, while the gun heads that do not fall into the unloading trough enter the unloading trough, and the conveying device may transport the gun heads back to the feeding trough.

[0027] In some embodiments, the base 110 is elongated, with its upper surface defining the working surface of the automatic cartoning device. The unloading device 120, the feeding trough 130, the feeding device 140, the unloading trough 150, and the conveying device 160 are disposed on it. In some embodiments, the upper surface of the base 110 may include an outer edge 111 around its perimeter, which can shield the bulk nozzles to prevent them from falling outside the automatic cartoning device during movement, thus avoiding contamination and waste. In some embodiments, the base 110 may include multiple chambers (such as a storage chamber 112, an electrical control chamber 113, etc.), which can accommodate structures with different functions. For example, the storage chamber 112 can be used to store bulk nozzles, nozzle boxes, etc.; the electrical control chamber 113 can be used to house an electrical control box that controls the operation of the automatic cartoning device, etc. In some embodiments, each chamber on the base can be opened to facilitate the loading and unloading of items and / or maintenance and repair.

[0028] In some embodiments, the discharge device 120 is inclinedly disposed above the base 110, with its lower end disposed on the upper surface of the base. Bulk discharge nozzles can slide down from the upper end to the lower end of the discharge device. During the sliding process, the nozzles can enter the discharge device due to their own gravity. No nozzles that do not enter the discharge device slide down from the lower end of the discharge device into the discharge trough 150. In some embodiments, the inclination angle of the discharge device 120 can be 120-140 degrees, preferably 130 degrees, so that the nozzles can also enter the discharge device while sliding down it.

[0029] In some embodiments, the feeding device 120 may include a slide 121, the bottom surface of which includes a sorting screen 122. The nozzles can slide down the slide 121 and, due to their own gravity, enter the sorting screen 122. The sorting screen sorts the nozzles that slide in, and nozzles that do not enter the sorting screen fall into the feeding trough 150. In some embodiments, the sorting screen can be removed from the feeding device, allowing for maintenance or replacement, and can accommodate nozzles of different sizes, increasing the adaptability of the automatic boxing device. In some embodiments, the sorting screen can also be placed in a nozzle box, allowing nozzles that are completely sorted on the sorting screen to be moved to the nozzle box for complete boxing.

[0030] refer to Figure 3A and Figure 3B , Figure 3A and Figure 3B This is a schematic diagram of a sorting screen structure according to an embodiment of this application. As shown, the sorting screen 122 includes a frame 310 and one or more sorting bars 320 disposed within the frame 310. The sorting bars 320 are arranged along the direction of the slide rail 121, and the nozzle can slide between adjacent sorting bars and be sorted among them. In some embodiments, the spacing between adjacent sorting bars is smaller than the maximum diameter of the nozzle, thereby allowing the nozzle to be accommodated between two sorting bars.

[0031] In some embodiments, the frame 310 may include multiple regions. For example, a sorting area 311 for sorting gun heads and other areas 312 outside the sorting area. The sorting area 311 is the same size as the opening at the bottom of the slide 121, allowing the gun heads to fall onto the sorting screen. The slide also conceals the structure of other areas, preventing the gun heads from falling into them. In some embodiments, the frame 310 may also include one or more dividing strips 313, which can be used to separate the sorting area 311 from other areas 312, thereby preventing the gun heads from being contained within the sorting area 311.

[0032] In some embodiments, the sorting screen 122 may further include multiple support legs 330, which may be disposed at the corners of the frame 310 to support the frame and thus support the nozzles arranged between the sorting bars 320, protecting them from contact with other items and causing contamination. In some embodiments, the sorting screen 122 may further include a panel 340, which is disposed on the frame 310 and located on the opposite side of the support legs. It can cooperate with the support legs to support the frame and, when the sorting screen is disposed on the feeding device and / or in the nozzle box, can shield the interior. In some embodiments, the height of the support leg box / or panel is greater than the length of the nozzle, thereby raising the nozzle to a certain height and preventing the nozzle from contacting other items. In some embodiments, the support legs 330 may also be hidden in the frame 310, thereby reducing the thickness of the sorting screen and facilitating storage.

[0033] In some embodiments, the sizing screen 122 may further include an adjusting device 350, which can be used to adjust the spacing between adjacent sizing bars, thereby enabling the sizing screen 122 to adapt to the arrangement of gun heads of different sizes and increasing the adaptability of the sizing screen 122. In some embodiments, the adjusting device 350 may include an adjusting screw 351 and a telescopic device 352. The telescopic device 352 is disposed between multiple sizing bars, and the adjusting screw 351 is connected to one of the sizing bars. By turning the adjusting screw, the telescopic device 352 can be adjusted, thereby adjusting the spacing between adjacent sizing bars. According to one embodiment of this application, the adjusting screw 351 is connected between the panel 340 and the sizing bar near the panel 340, thereby adjusting the position of the sizing bar near the panel 340 by adjusting the screw, and thus adjusting the telescopic device. In some embodiments, the telescopic device 352 may be a telescopic head, a telescopic rod, a hydraulic rod, a pneumatic rod, etc. In some embodiments, the adjusting device 350 may further include an adjusting button 353, which may be disposed on the panel 340 and connected to the adjusting screw, and can be used to turn the adjusting screw.

[0034] In some embodiments, the sorting screen 122 may also include a locking device 360, which may be disposed on the frame to lock and fix the sorting screen to the feeding device and / or the nozzle box, preventing displacement of the sorting screen 122 and affecting the sorting of the nozzles. In some embodiments, the locking device may be a slot, which may be disposed at the corner of the frame and may engage with the feeding device and / or the nozzle box, thereby fixing the frame in the feeding device and / or the nozzle box.

[0035] In some embodiments, the feeding trough 130 is disposed on the upper surface of the base 110, and its horizontal height is lower than the lower horizontal height of the unloading device. The feeding device 140 conveys the nozzle head to the upper end of the unloading device. In some embodiments, the feeding trough may also be inclined towards the unloading device 120 to facilitate the sliding of the nozzle head in the feeding trough towards the unloading device, which is beneficial for the feeding device to convey the nozzle head. In some embodiments, the feeding trough 130 may also be disposed above the base. For example, its horizontal height is higher than the upper end of the unloading device, allowing the nozzle head to slide directly into the upper end of the unloading device via the inclined feeding trough.

[0036] In some embodiments, the feeding device 140 is inclinedly disposed between the feeding trough 130 and the unloading device 120, and connected to both, so as to convey the nozzle in the feeding trough 130 to the upper end of the unloading device 120. (See reference) Figure 2D In some embodiments, the feeding device 140 may be a push-plate type feeding device, which includes multiple stepped push plates 141 and a driving device 142. The push plates 141 move in a reciprocating linear motion, driving the gun head from the lower end to the upper end of the stepped push plates. The driving device 142 may be disposed in a base and used to drive the reciprocating linear motion of the push plates. In some embodiments, the driving device 142 may be an electric motor or a reducer. In some embodiments, the feeding device may also include a guide groove 143, which can be used to guide the movement trajectory of the push plates and ensure the reciprocating linear motion of the push plates. In some embodiments, the feeding device 140 may also be other structures, such as a conveyor belt or other feeding devices.

[0037] In some embodiments, the discharge trough 150 is disposed on the upper surface of the base 110 and connected to the lower end of the discharge device 120. When the nozzle slides down from the lower end of the discharge device, it can enter the discharge trough 150. In some embodiments, the discharge trough 150 can be slightly inclined, with its inclination direction being the same as that of the discharge device. After the nozzle slides into the discharge trough, it can move away from the discharge device, avoiding the stacking of nozzles that slide into the discharge trough and affecting the nozzle sorting of the discharge device. It also facilitates the entry of the nozzle into the conveying device.

[0038] In some embodiments, the conveying device 160 is disposed on the upper surface of the base 110 and connected to the discharge chute 150 and the loading chute 130, and can convey the gun head in the discharge chute to the loading chute. In some embodiments, the conveying device 160 is connected to the lower end of the discharge chute, thereby facilitating the entry of the gun head into the conveying device. In some embodiments, the conveying device 160 is connected to the upper end of the loading chute, thereby facilitating the entry of the gun head into the loading chute. In some embodiments, the horizontal height of the discharge chute is higher than the horizontal height of the loading chute, and the conveying device 160 can be a rotary slide that connects the loading chute and the discharge chute. After the gun head falls into the discharge chute, it enters the lower end of the discharge chute, thereby entering the rotary slide, and then entering the loading chute via the rotary slide.

[0039] In some embodiments, the automatic cartoning device 100 may further include a cover 170. This cover can be disposed above the base 110 and can cover the material feeding device 120, the feeding chute 130, the feeding device 140, the material feeding chute 150, and the conveying device 160 disposed above the base, preventing dust from entering and preventing the nozzles from falling outside the automatic cartoning device. In some embodiments, the cover 170 can be a split-opening type, allowing selection of the opening method according to actual needs, suitable for different usage scenarios. For example, when part of the nozzle is stuck, only the stuck portion of the cover needs to be opened, avoiding the full opening of the cover affecting other structures.

[0040] The automatic cartoning device of this application places bulk gun heads into the feeding trough. The gun heads automatically slide down the inclined feeding trough to the feeding device, which then conveys them to a discharge device. The gun heads slide down the discharge device and are sorted on it. Gun heads that do not enter the discharge device slide into the discharge trough and are then conveyed back to the feeding trough, thus achieving automatic cartoning. In some embodiments, after the gun heads are sorted on the discharge device, they can be directly placed into the gun head box. In some embodiments, after the gun heads are sorted on the discharge device, a picking and cartoning device can be used to place the sorted gun heads into the gun head box. This application also proposes a gun head picking and cartoning device, which will be described in detail below.

[0041] Figures 4A-4D This is a schematic diagram of a picking and packing device according to an embodiment of this application. Figure 4A and Figure 4B These are a perspective view and a side view of the picking and packing device. Figure 4C and Figure 4D This is a schematic diagram of two different operating states of the picking and packing device.

Each pickup strip 420 may include one or more locking connectors 421 on its outer side facing the box body, which can pick up the sorted gun tips. The adjusting device 430 can be used to adjust the spacing between the pickup strips. For example, after the gun tips are sorted and adjacent gun tips are closely arranged, the adjusting device adjusts the pickup strips to fit tightly together, allowing the pickup strips to pick up the sorted gun tips. After the pickup strips have finished picking up the gun tips, the adjusting device can increase the spacing between the pickup strips to accommodate different gun tip box sizes. In some embodiments, the locking connectors are arranged at equal intervals on the pickup strips. The spacing between the locking connectors is the same as the spacing between the holes in the gun tip box, so as to place the picked-up gun tips into the corresponding holes in the gun tip box.

[0043] In some embodiments, the housing 410 may include baffles 411 and 412 and a connecting rod 413 disposed between the baffles 411 and 412. The connecting rod 413 connects the baffles 411 and 412, and multiple pickup strips pass through the connecting rod 413 and can move between the baffles 411 and 412. In some embodiments, the spacing between the baffles 411 and 412 may be the same as the width of the gun head housing. In some embodiments, the connecting rod 413 may be connected to both ends of the baffles 411 and 412, and the pickup strips are at least disposed on the connecting rod at one end of the baffles 411 and 412. In some embodiments, at least a portion of the connecting rod 413 has a strip-shaped hole for connecting to the baffles 411 and / or baffles 412 to facilitate the movement of the pickup strips.

[0044] In some embodiments, the pickup strip 420 may include a first pickup strip 422 and a second pickup strip 423, which are respectively disposed at both ends of the housing and pass through the connecting rods at both ends of the baffles 411 and 412.

Thus, the second pickup strip 423 can move between a first position and a second position. When the second pickup bar 423 is in the first position, it is away from the first pickup bar 422, and the locking connector on the pickup bar can pick up the gun head. When the second pickup bar 423 is in the second position, it is close to the first pickup bar 422, and the locking connector on the pickup bar can remove the gun head. In some embodiments, similarly, the connecting hole between the connecting rod connected to the first pickup bar 422 and the baffles 411 and 412 can be a strip-shaped hole, the connecting rod connected to the second pickup bar 423 is fixedly connected to the baffles 411 and 412, and the first pickup bar 422 can move between the first position and the second position.

[0045] In some embodiments, the pickup and boxing device 400 further includes an unloading device 440, which may include a plurality of push blocks 441 and support rods 442 connected to the push blocks. The push blocks 441 may be disposed in the second pickup strip and located between the snap-fit ​​connectors of the pickup strip; the support rods 442 may also be connected to the first pickup strip, connecting the push blocks to the first pickup strip. In some embodiments, two adjacent snap-fit ​​connectors 421 may correspond to one push block 441, that is, the push blocks 441 are disposed between two adjacent snap-fit ​​connectors.

[0046] refer to Figure 4C and Figure 4D In some embodiments, the push block can move along the extension direction of the latch connector, thereby pushing the gun head picked up by the latch connector off. For example, pressing the first pickup bar moves the support rod towards the second pickup bar, thereby causing the push block to move in the extension direction of the latch connector and push the gun head off the latch connector. In some embodiments, the position of the push block can also be fixed, and by pressing the second pickup bar, the latch connector can move towards the first pickup bar, thereby pushing the push block to push the gun head off the latch connector.

[0047] In some embodiments, the pickup and packaging device 400 may further include a reset device 450, which may be disposed between the first pickup strip and the second pickup strip, and may reset a moved pickup strip. For example, when the second pickup strip moves, it may restore the second pickup strip to its original position. In some embodiments, the reset device may be a reset spring, which may be sleeved on the support rod 442 and located between the first pickup strip and the second pickup strip.

[0048] In some embodiments, the adjusting device 430 may include a plurality of adjusting rods 431 and a telescopic portion 432.

[0049] In some embodiments, the adjusting rod is connected to a second pickup strip that is further away. By pulling the adjusting rod, the pickup strip can be moved closer to the center or one side of the housing. In some embodiments, multiple adjusting rods 431 can also be connected to multiple different pickup strips, thereby adjusting the spacing between different pickup strips or reducing the difficulty of adjustment. In some embodiments, the adjusting rod can also be a partial connecting rod. In some embodiments, the telescopic part can be one or more of a telescopic head, a telescopic rod, a hydraulic rod, and a pneumatic rod.

[0050] The working process of the pickup and boxing device of this application is as follows: After the gun heads are sorted, the locking connector of the pickup and boxing device is aligned with the sorted gun heads, and the pickup device is pressed down.
