A box loading device

Abstract

The present invention provides a box loading device, which comprises a base, a feeding mechanism and a combing box. When the box loading device works, the combing teeth pick up the pipette tips, and the combing box continues to move forward along the first direction until the box body moves to directly below the feeding mechanism. The pipette tip enters the guiding sliding hole through the feeding port, and the bottom of the pipette tip extends to the accommodating cavity. The tip box is placed in the accommodating cavity. During the process of the pipette tip sliding into the guiding sliding hole, it simultaneously enters the strip-shaped sliding hole of the tip box to pre-insert the lower part of the pipette tip into the tip box. After each pipette tip moves and aligns with the tip hole, the combing box moves away from the feeding mechanism along the extending direction of the sliding hole, and the frontmost pipette tips in each row of the sliding holes fall to the guiding sliding hole through the tail of the sliding hole, and then fall to the tip hole through the guiding sliding hole. Before the pipette tip falls, its lower part has been pre-inserted into the tip box, and the falling distance is short, effectively preventing the pipette tip from tilting and ensuring the loading effect and loading efficiency of the pipette tip.

Description

Technical Field

[0001] The present invention relates to the technical field of packaging for biological experiment utensils, and particularly to a box loading device. Background Art

[0002] Some equipment, such as pipette tips, are basic consumables for pipettes to aspirate liquids. For convenient use, the pipette tips are usually neatly arranged in a tip box. When the tips in a tip box are used up, generally, people need to manually rearrange and insert the loose pipette tips into the tip box, which takes a long time.

[0003] In the prior art, a box loading device for transferring loose pipette tips into a tip box includes a feeding mechanism and a picking mechanism. The feeding mechanism is used to convey pipette tips to a picking station. The head of the pipette tip is clamped by the feeding mechanism. Before picking, the picking mechanism is located on the side of the conveying direction of the feeding mechanism. Manually operate to make the picking mechanism insert and pick up the pipette tip from the bottom. The picking mechanism moves perpendicular to the conveying direction until it runs directly below the feeding mechanism to position the pipette tip on the picking mechanism. Then, the tip box is clamped at the bottom of the picking mechanism, and the clamping of the feeding mechanism on the pipette tip is released so that the pipette tip falls through the dropping hole on the picking mechanism into the tip hole.

[0004] In the above box loading device, the pipette tip freely falls and inserts into the tip hole. Since there is a picking mechanism between the feeding mechanism and the tip box during dropping, the dropping distance of the pipette tip is high. Due to the light weight of the pipette tip, with a high dropping distance, the pipette tip is prone to skew during the dropping process and cannot be inserted into the corresponding tip hole, resulting in low transfer efficiency.

[0056] Embodiment

[0057] This embodiment provides a cartoning device, such as Figure 1 and Figure 2As shown in the figure, it includes a base 50, a feeding mechanism 10 and a material sorting box 30. Among them, the feeding mechanism 10 includes a feeding mechanism 102 arranged on the base 50; multiple rows of parallel and spaced sliders 10221 are arranged on the feeding mechanism 102; the feeding mechanism 102 is used to convey pipette tips to the tail ends of the sliders 10221; the material sorting box 30 is arranged below the sliders 10221 and can move horizontally in two dimensions; the material sorting box 30 includes a box body 301 and multiple rows of material sorting teeth 302. Among them, a receiving cavity 3013 and an open opening 30111 communicating with the receiving cavity 3013 are arranged on the box body 301; multiple rows of parallel strip-shaped guiding sliders 3014 are arranged on the top of the box body 301; a feeding port 30121 is arranged on the box body 301 at the end of the guiding slider 3014, and the feeding port 30121 communicates with the guiding slider 3014 and the receiving cavity 3013. The guiding slider is suitable for the pipette tip to fall through; a tip box 20 is suitable for being arranged in the receiving cavity 3013; multiple rows of parallel strip-shaped sliders 2021 are opened on the top plate 202 of the tip box 20, and multiple rows of tip holes 2022 are arranged on the strip-shaped sliders 2021. The diameter of the tip holes 2022 is larger than the width of the strip-shaped sliders 2021; an opening 20111 is arranged on the first side plate 2011 at one end of the strip-shaped slider 2021. The opening 20111 is arranged corresponding to and communicating with the strip-shaped slider 2021; the opening 20111 corresponds to and communicates with the feeding port 30121 one by one.

[0058] When the cartoning device with this structure is working, the bulk pipette tips are placed on the feeding mechanism 102. Under the action of external force, multiple columns of pipette tips fall into the sliding holes 10221 and are conveyed towards the tail end of the sliding holes 10221. The head of the pipette tip is clamped on the top surface of the sliding hole 10221, and the tail extends below the sliding hole 10221. The combing box 30 is initially located on the side of the feeding mechanism 102. The combing box 30 moves from the side towards the bottom of the feeding mechanism 102 in the first direction. The combing teeth 302 pick up the pipette tips. The combing box 30 continues to move forward in the first direction until the box body 301 moves to directly below the feeding mechanism 102. The pipette tips enter the guiding sliding hole 3014 through the feeding port 30121, and the bottom of the pipette tip extends into the accommodating cavity 3013. The tip box 20 is placed in the accommodating cavity 3013. During the process of the pipette tip sliding into the guiding sliding hole 3014, it simultaneously enters the strip-shaped sliding hole 2021 of the tip box 20, so as to pre-insert the lower part of the pipette tip into the tip box 20. After each pipette tip moves and aligns with the tip hole 2022, the combing box 30 moves away from the feeding mechanism 102 along the extension direction of the sliding hole 10221 (the second direction). The frontmost pipette tips on each column of the sliding holes 10221 fall into the guiding sliding hole 3014 through the tail end of the sliding hole 10221, and then fall to the tip hole 2022 through the guiding sliding hole 3014. Before the pipette tip falls, its lower part has been pre-inserted into the tip box 20, and the falling distance is short, effectively preventing the pipette tip from tilting and ensuring the loading effect and loading efficiency of the pipette tip. The combing box 30 continues to move in the second direction until all rows of pipette tips pass through the tail end of the sliding hole 10221 and fall to the tip hole 2022, completing the transfer and installation of the pipette tips.

[0059] On both sides outside any opening 20111, there are guiding inclined surfaces 20112. The guiding inclined surfaces 20112 are arranged to connect with the feeding port 30121, so as to guide the pipette tip from the feeding port 30121 to the strip-shaped sliding hole 2021 and guide the pipette tip to smoothly enter the opening 20111. The guiding inclined surfaces 20112 on both sides outside any opening 20111 are in a flared shape.

[0060] The guiding inclined surface 20112 is formed on the first side plate 2011, that is, the guiding inclined surface 20112 is located on the outer side in the thickness direction of the first side plate 2011, and the opening 20111 is located on the inner side. The outer end of the guiding inclined surface 20112 is flush with the outer wall of the first side plate 2011, and the structure is flat and compact. The side plate 201 of the tip box 20 is flat, which is convenient for inserting it into the accommodating cavity 3013 for positioning.

[0061] See Figure 6 and Figure 7 , the end of the tip box 20 extends out of the accommodating cavity 3013, that is, the length of the tip box 20 is greater than the length of the accommodating cavity 3013, which is convenient for placing or taking out the tip box 20 from the end.

[0062] See Figure 8, the bottom of the opening 20111 is arranged close to the bottom surface of the first side plate 2011, and the vertical depth of the opening 20111 is deep. The depth at which the pipette tip extends below the top plate 202 is relatively deep, that is, its preloading depth is deep. As a result, the part of the pipette tip located above the top plate 202 is short, and the free fall distance of the pipette tip is short, further ensuring that the pipette tip falls vertically through the tip hole 2022 during the falling process. At the same time, the vertical depth of the opening 20111 is relatively deep, allowing the pipette tip box 20 with a longer depth to enter to accommodate the filling of pipette tips of different specifications.

[0063] See Figure 8 and Figure 9 , the inner wall of the opening 20111 is flush with the inner wall of the strip-shaped sliding hole 2021 to ensure the passing of the pipette tip and enable the pipette tip to smoothly slide into the strip-shaped sliding hole 2021 from the opening 20111. That is, the widths of the opening 20111 and the strip-shaped sliding hole 2021 are the same, and this width is the first width. The first width is less than the head diameter of the pipette tip and greater than its tail diameter. The diameter of the tip hole 2022 is less than the head diameter of the pipette tip, so that the head of the pipette tip is clamped at the top of the tip hole 2022. The sizes of the first width and the diameter of the tip hole 2022 can be adjusted adaptively according to different models of pipette tips.

[0064] The pipette tip box 20 includes a top plate 202 and side plates 201. The top plate 202 is arranged on the inner wall of the side plates 201, and the top surface of the top plate 202 is flush with the top surface of the side plates 201. The pipette tip box 20 has a compact structure and good integrity.

[0065] Optionally, the pipette tip box 20 is in the shape of a rectangular box. The strip-shaped sliding holes 2021 extend along the width direction of the top plate 202, and each row of strip-shaped sliding holes 2021 is arranged at equal intervals along the length direction of the top plate 202. Multiple columns of tip holes 2022 are arranged at equal intervals.

[0066] Optionally, the top plate 202 and the side plates 201 are integrally formed, and the pipette tip box 20 has good structural integrity and a stable and reliable overall structure.

[0067] See Figures 3 to 5 , multiple columns of falling holes 3015 are provided on the guiding sliding holes 3014 of the combing box 30. The diameter of the falling holes 3015 is greater than the width of the guiding sliding holes 3014; the falling holes 3015 are arranged in one-to-one correspondence with the tip holes 2022. The diameter of the falling holes 3015 is greater than the head diameter of the pipette tip, and the head diameter of the pipette tip is greater than the width of the guiding sliding holes 3014. The pipette tip can only fall from above the falling holes 3015 to the tip holes 2022. The falling holes 3015 are arranged in one-to-one correspondence with the tip holes 2022 to ensure that the pipette tip accurately falls into the tip holes 2022. The pipette tip box 20 is placed in the accommodating cavity 3013 to ensure that the tip holes 2022 and the falling holes 3015 are vertically aligned.

[0068] The cartridge body 301 includes a first side portion 3011 and a second side portion 3012. An open mouth 30111 is provided on the first side portion 3011, and a feeding port 30121 is provided on the second side portion 3012 and is arranged in one-to-one correspondence with the guiding sliding holes 3014. Multiple rows of comb-shaped teeth 302 are arranged at intervals at the outer end of the cartridge body 301. The adjacent comb-shaped teeth 302 enclose a material guiding channel 303, and the material guiding channel 303 communicates with the feeding port 30121.

[0069] Optionally, the cartridge body 301 is in the shape of a rectangular box. The guiding sliding holes 3014 extend along the width direction of the cartridge body 301, and each row of guiding sliding holes 3014 is arranged along the length direction of the cartridge body 301. Preferably, each row of guiding sliding holes 3014 is arranged at equal intervals, and each column of dropping holes 3015 is arranged at equal intervals to adapt to the positions of the nozzle holes 2022 on the nozzle cartridge 20. Optionally, the first side portion 3011 is adjacent to the second side portion 3012; the spacing between each row of guiding sliding holes 3014 and the spacing between each column of dropping holes 3015 can be adaptively adjusted according to the positions of the nozzle holes 2022. The width of the guiding sliding holes 3014 and the diameter of the dropping holes 3015 are adjusted according to the model of the pipette nozzle to be installed to adapt to the installation of nozzle holes 2022 of different models.

[0070] See Figure 3 and Figure 5 , the upper part of any dropping hole 3015 is in the shape of a flared inclined plane to guide the pipette nozzle to slide down. The dropping hole 3015 is formed by two arc surfaces recessed on the inner wall of the guiding sliding hole 3014, and the upper half opening 20111 of the dropping hole 3015 gradually decreases from top to bottom.

[0071] See Figures 3 to 5 , the total length of the first ends 3021 of all the comb-shaped teeth 302 facing away from the cartridge body 301 is less than the length of the cartridge body 301, and the comb-shaped teeth 302 extend in an arc towards the second end 3022 of the cartridge body 301. That is, the spacing between the first ends 3021 of the adjacent comb-shaped teeth 302 is small, and the spacing between the second ends 3022 is large. A feeding mechanism 10 for transporting pipette nozzles is provided with multiple columns of sliding holes 10221 arranged at intervals. When the pipette nozzles are transported to the rear ends of the sliding holes 10221, the multiple pipette nozzles on each column of sliding holes 10221 are arranged in contact with each other front and back. The first spacing between the front and back rows of pipette nozzles is small, but the second spacing between the front and back rows of nozzle holes 2022 on the nozzle cartridge 20 is greater than the first spacing. The comb-shaped teeth 302 pick up the pipette nozzles from the side and continue to move forward. After each column of pipette nozzles reaches the second end 3022 of the comb-shaped teeth 302, the spacing between the front and back rows of pipette nozzles becomes larger to screen the pipette nozzles into the required row spacing.

[0072] The second end 3022 of the material combing tooth 302 is smoothly connected to the inner wall of the material inlet 30121. The inner side wall of the material inlet 30121 is flush with the inner side wall of the guiding sliding hole 3014. During the process of inserting and taking the pipette tip into the falling hole 3015, the inner walls it contacts are all smooth inner walls, avoiding damaging the pipette tip during the transfer and installation process.

[0073] Each material combing tooth 302 is thinner at the top and thicker at the bottom, so that the adjacent material combing teeth 302 enclose a material guiding channel 303 that is wider at the top and narrower at the bottom. Since the pipette tip is thicker at the top and thinner at the bottom, the material guiding channel 303 that is wider at the top and narrower at the bottom can better fit the outer wall of the pipette tip, preventing the pipette tip from tilting, so as to guide the pipette tip to slide smoothly into the guiding sliding hole 3014.

[0074] See Figures 3 to 5 , a first bottom plate 304 is arranged outside the second side part 3012, and the material combing teeth 302 are arranged on the first bottom plate 304 to improve the strength of the material combing teeth 302 and keep their shapes fixed to ensure the material taking and guiding effects.

[0075] Optionally, the bottom surface of the first bottom plate 304 is flush with the bottom surface of the box body 301. The material combing box 30 is integrally formed, and its structure is stable and firm.

[0076] See Figure 1 and Figure 2 , the box loading device further includes a translation mechanism 40. The translation mechanism 40 includes a mounting seat 401, a first translation driving mechanism 402 and a second translation driving mechanism 403. Among them, the material combing box 30 is movably arranged on the mounting seat 401; the first translation driving mechanism 402 is adapted to drive the mounting seat 401 to move along the extension direction (the second direction) of the sliding hole 10221; the second translation driving mechanism 403 is adapted to drive the material combing box 30 to move along the direction perpendicular to the extension direction (the first direction) of the sliding hole 10221. The second translation driving mechanism 403 drives the material combing box 30 to reciprocate along the first direction, and the first translation driving mechanism 402 drives the material combing box 30 to reciprocate along the second direction, realizing full-automatic material taking and blanking, automatically completing the transfer and installation of the pipette tip, and having high transfer and installation efficiency.

[0077] Optionally, the translation mechanism 40 further includes a first rack, a first gear, a second rack, a second gear, and a support base. The first rack is fixed to the top surface of the base 50. The first translation driving mechanism 402 is a first motor, which is fixed to the mounting base 401 and its output shaft extends to the bottom of the mounting base 401 to connect to the first gear, and the first gear meshes with the first rack. On each side of the first rack, there is a set of first guiding mechanisms for guiding the mounting base 401 to move in the second direction. Any set of first guiding mechanisms includes a first guide rod and bearing seats supported at both ends of the guide rod; at least two linear bearing seats are sleeved on each guide rod, the top of the linear bearing seat is connected to the mounting base 401, and the linear bearing seat slides along the guide rod to guide the smooth movement of the mounting base 401. The first rack extends in the second direction. The second rack is fixed to the top surface of the mounting base 401 and extends in the first direction, and the extending direction of the second rack is perpendicular to the first rack. The support base is arranged above the mounting base 401, the material combing box 30 is fixed to the support base, the second translation driving mechanism 403 is a second motor, which is fixed to the support base and its output shaft extends to the bottom of the support base to connect to the second gear, and the second gear meshes with the second rack. On each side of the second rack, there is a set of second guiding mechanisms for guiding the movement of the support base. The difference between the structure of the second guiding mechanism and the first guiding mechanism is that a bearing seat support is added in the middle of its second guide rod.

[0078] The middle of the support base is concave upward to raise the height of the material combing box 30. The material combing box 30 is close to the feeding mechanism 102 in the height direction, and at the same time provides a receiving space for accommodating the first motor. The two sides of the support base extend horizontally to connect to the bearing seats.

[0079] See Figure 10 and Figure 11 As shown in and, the feeding mechanism further includes a frame 101 and a conveying driving mechanism 103. Among them, the frame is arranged on the base, and the feeding mechanism 102 is arranged on the frame 101; a storage bin 1021 is arranged on one side of the feeding mechanism 102, a sliding hole 10221 is arranged on the second bottom plate 1022 of the feeding mechanism 102, the sliding hole 10221 extends along the length direction of the second bottom plate 1022, and the head and tail ends of the sliding hole 10221 are respectively located inside and outside the storage bin 1021; on the baffle 1023 of the storage bin 1021 spanning the sliding hole 10221, there is a convex feeding port 10231, and the feeding port 10231 is arranged in one-to-one correspondence with the sliding hole 10221; the head of the pipette tip is adapted to be clamped on the top of the sliding hole 10221, and the feeding port 10231 allows the head of the pipette tip to slide through; the conveying driving mechanism 103 is used to drive the feeding mechanism 102 to move to convey the pipette tip to the tail end of the sliding hole 10221.

[0080] When the feeding mechanism is working, the loose pipette tips are poured into the storage bin 1021. The conveying drive mechanism 103 moves, causing the pipette tips to fall into the sliding holes 10221. The head of the pipette tip is clamped at the top of the sliding hole 10221, and the lower part of the tip extends below the sliding hole 10221 and enters the sliding hole 10221 outside the storage cavity through the feeding port 10231. Multiple pipette tips in each column of sliding holes 10221 are arranged in sequence front and back to form multiple rows of pipette tips. Multiple columns of neatly arranged pipette tips are simultaneously automatically conveyed towards the tail of the sliding hole 10221, facilitating the subsequent material taking by the combing box.

[0081] See Figure 10 and Figure 11 , the feeding mechanism further includes a clogging prevention mechanism 104. The clogging prevention mechanism 104 includes a rotary drive source 1041 and a cleaning component 1042 provided at the drive end of the rotary drive source 1041. The cleaning component 1042 is located inside the storage bin 1021, and the rotation path of the cleaning component 1042 covers the feeding port 10231. Since the upper part of the sliding hole 10221 is blocked by the baffle 1023, the pipette tips are prone to clogging at the baffle 1023. When the clogging prevention mechanism 104 is working, the rotary drive source 1041 drives the cleaning component 1042 to rotate. The cleaning component 1042 rotates from top to bottom to the feeding port 10231 and sweeps the accumulated pipette tips towards the storage bin 1021 in the direction away from the feeding port 10231, preventing the pipette tips from clogging at the feeding port 10231.

[0082] Optionally, the rotary drive source 1041 is a motor, which is fixed on the outer side wall of the storage bin 1021, and the motor shaft extends into the storage bin 1021 to connect the cleaning component 1042. For example, the cleaning component 1042 is a brush, the brush fixing rod is connected to the motor output shaft, and the brush is horizontally arranged above the sliding hole 10221 in front of the feeding port 10231. Optimally, the brush is in a vertical state, and the bottom cleaning surface of the brush fits the top surface of the second bottom plate 1022, with good cleaning effect.

[0083] See Figures 10 to 12 , the baffle 1023 is inclined downward towards the inside of the storage bin 1021. When the pipette tips are docked at the baffle 1023, they can automatically slide down along the inclined surface of the baffle 1023 to the second bottom plate 1022, enabling the pipette tips to enter the rotation path area of the brush and cooperating with the brush to effectively prevent the accumulation of pipette tips.

[0084] See Figure 12 , the baffle 1023 is thinner at the top and thicker at the bottom, and the feeding port 10231 is along the thickness direction of the baffle 1023 ( Figure 12extends in the left - right direction (in the figure); the feeding mechanism further includes a cover plate 1024, which is connected to the baffle 1023 and is arranged outside the storage bin 1021 and covers the upper part of the sliding hole 10221. The cover plate 1024 has a limiting surface 10241 for restricting the upward jump of the pipette tip; the limiting surface 10241 is located above the top wall of the feeding port 10231 or is flush with the top wall of the feeding port 10231. That is, the limiting surface 10241 is connected to the top wall of the feeding port 10231 of the baffle 1023. When the feeding mechanism works, the limiting surface 10241 and the top wall of the feeding port 10231 are located above the end of the pipette tip. In the case where the vibration force of the conveying driving mechanism 103 is relatively large, it can effectively prevent the pipette tip from jumping upward out of the sliding hole 10221, so as to convey the pipette tip along the sliding hole 10221 to the tail of the sliding hole 10221. Optimally, the limiting surface 10241 is located above the top wall of the feeding port 10231 to ensure that the pipette tip smoothly enters the area of the cover plate 1024.

[0085] Optionally, the longitudinal section of the baffle 1023 is a right - angled triangle. The side wall of the storage bin 1021 outside the baffle 1023 is fixed to the baffle 1023 by bolts. The side wall of the storage bin 1021 is a rectangular frame, and there is a flanging at the bottom of one end of the rectangular frame, and the flanging is fixed to the second bottom plate 1022. The two sides of the rectangular frame outside the storage bin 1021 extend towards the tail direction of the second bottom plate 1022 to form a retaining wall for shielding the cover plate 1024. There is an inner flanging on the retaining wall, and the retaining wall is fixed to the second bottom plate 1022 through this flanging.

[0086] See Figure 14 As shown in, a plurality of sliding grooves 10242 are correspondingly arranged on the cover plate 1024 above the sliding hole 10221. The bottom wall of the sliding groove 10242 is the limiting surface 10241, and the width of the sliding groove 10242 is greater than the width of the sliding hole 10221. The pipette tip slides out of the storage bin along the sliding hole 10221, and the head of the pipette tip is placed in the sliding groove 10242 to guide the movement of the pipette tip and prevent the pipette tip from skewing. The bottom surface of the cover plate 1024 outside the sliding groove 10242 is attached to the top surface of the second bottom plate 1022, and both sides in the width direction of the cover plate 1024 are fixed to the second bottom plate 1022.

[0087] See Figure 11 As shown in, an elastic limiting member 1025 is provided at the top of the tail end of the sliding hole 10221. The elastic limiting member 1025 extends along the length direction of the sliding hole 10221, and one end of the elastic limiting member 1025 facing the storage bin 1021 is adapted to abut against the head of the pipette tip. See Figure 13, the width of the tail end of the sliding hole 10221 is greater than that of its front end. Since the comb teeth of the combing box are arranged at equal intervals, multiple rows of pipette tips are conveyed to the elastic limiting member 1025. The limiting member abuts against the pipette tips, causing the pipette tips in each row to abut against each other successively front and back. The elastic limiting member 1025 arranges the frontmost row of pipette tips close to the tail end of the sliding hole 10221, so that the pipette tips in each row are aligned, facilitating the combing box to insert and pick up the pipette tips correspondingly from the bottom of the second base plate 1022. The combing box inserts and picks up the pipette tips from one side of the second base plate 1022 and moves downward towards the directly below of the second base plate 1022. Then the combing box moves towards the tail of the sliding hole 10221, driving the pipette tips to squeeze the elastic limiting member 1025. The frontmost row of pipette tips moves to the tail end of the sliding hole 10221. Due to the large width of the tail end of the sliding hole 10221, the pipette tips automatically fall onto the combing box under the action of gravity. The subsequent rows of pipette tips move to the tail of the sliding hole 10221 in sequence and fall onto the combing box, realizing the simultaneous picking of multiple rows and multiple columns of pipette tips.

[0088] See Figure 12 , the sliding groove 10242 extends above the tail of the sliding hole 10221. There are multiple elastic limiting members 1025 which are arranged in the sliding groove 10242 in one-to-one correspondence. Each elastic limiting member 1025 can separately and independently abut against each column of pipette tips. The elastic limiting member 1025 is embedded in the sliding groove 10242 to guide and limit it during the contraction process.

[0089] The tail end of the sliding groove 10242 is closed to limit the elastic limiting member 1025. The tail end of the elastic limiting member 1025 is fixed on the cover plate 1024 by bolts. Optionally, the elastic limiting member 1025 is a spring.

[0090] Preferably, multiple rows of sliding holes 10221 are arranged at equal intervals to convey multiple rows of pipette tips arranged at equal intervals simultaneously.

[0091] See Figure 10 and Figure 11 , the conveying driving mechanism 103 is a linear vibrator. The linear vibrator is arranged on the frame 101; the linear vibrator is connected to the feeding mechanism 102. The linear vibrator reciprocates to convey the pipette tips towards the tail end of the sliding hole 10221. The top of the linear vibrator is connected to the second base plate 1022 of the feeding mechanism 102.

[0092] This loading device is also suitable for conveying and transferring any equipment with a large head and a small lower part. The lower part of the equipment can automatically slide into the sliding hole 10221 under the vibration action of the conveying driving mechanism 103, and the head can be clamped at the top of the sliding hole 10221 and then freely fall into the tip hole. For example, the equipment can be a test tube or the like.

[0093] As the first alternative embodiment of this embodiment, the conveying drive mechanism 103 can also be a vibration motor. The bottom plate 1022 of the feeding mechanism 102 is fixed to the frame 101 through springs, and the vibration motor is fixed to the feeding mechanism 102. The conveying drive mechanism 103 can also be a reciprocating motor. One end of the reciprocating motor is fixed to the frame 101, and the output end is connected to the feeding mechanism 102. The reciprocating motor drives the feeding mechanism 102 to reciprocate horizontally back and forth to feed materials.

[0094] As the second alternative embodiment of this embodiment, the elastic limiting member 1025 can also be any other element having the same performance as the spring. The elastic limiting member 1025 can also be an integral structure, and its width extends along the width direction of the bottom plate 1022. The elastic limiting member 1025 abuts against each row of pipette tips as a whole or is compressed under pressure. At this time, a through groove for accommodating the elastic limiting member 1025 is correspondingly provided on the cover plate 1024.

[0095] As the third alternative embodiment of this embodiment, the chute 10242 may not be provided on the cover plate 1024, and the bottom surface of the cover plate 1024 directly serves as the limiting surface 10241 to limit the jumping of the pipette tips.

[0096] As the fourth alternative embodiment of this embodiment, the first translation drive mechanism 402 and the second translation drive mechanism 403 can also be linear drivers such as hydraulic cylinders or air cylinders. The driving ends of the two linear drivers are respectively connected to the mounting seat 401 and the combing box 30 to drive the combing box 30 to move automatically in two dimensions.

[0097] As the fifth alternative embodiment of this embodiment, the falling hole 3015 may not be provided in the guiding sliding hole 3014, so that the width of the guiding sliding hole 3014 is greater than the head of the pipette tip, and the pipette tip directly falls into the tip box 20 through the guiding sliding hole 3014.

[0098] As the sixth alternative embodiment of this embodiment, the tail of the sliding hole can be provided with an opening, and a shielding plate is provided at the tail of the sliding hole. When the combing box takes materials, the shielding plate is opened so that the pipette tip slides out through the opening at the tail of the sliding hole.

[0099] As the seventh alternative embodiment of this embodiment, the conveying drive mechanism 103 may not be provided on the feeding mechanism, and the feeding mechanism is directly shaken manually to make the pipette tips fall into the sliding hole.

[0100] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
