Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated production equipment technology, and in particular to a pipette filter assembly device. Background Technology
[0002] A pipette is a tool used for the quantitative transfer of liquids. In analytical testing, pipettes are typically used to transfer small or minute amounts of liquid, with the pipette tip used to aspirate the liquid. When the pipette tip aspirates liquid, the liquid drawn into the tip generates aerosols. To prevent aerosols or liquid from entering the pipette and contaminating it, a filter cartridge is usually installed inside the pipette tip.
[0003] In existing technologies, automated assembly equipment is typically used to assemble filter cartridges and pipette tips. A large number of filter cartridges are added to a hopper, and then a conveyor transports them to a receiving trough on a docking platform connected to the feeding channel. The docking platform then flips the filter cartridges upwards, and the suction nozzle of the pick-up device picks up the cartridges from the receiving trough and moves them above the pipette tip. Finally, the cartridges are lowered, assembling them into the pipette tip. However, due to the soft material and numerous burrs on the surface of the filter cartridges, adjacent cartridges often stick together. When the docking platform flips the cartridges upwards, cartridges not yet in the receiving trough are also flipped upwards by those already in the trough and accumulate at the trough opening. When the suction nozzle picks up the cartridges, it simultaneously picks up cartridges from both the receiving trough and the opening, assembling them all into the pipette tip. This renders the produced pipette tips unusable, reducing production efficiency and increasing production costs. Utility Model Content
[0004] The purpose of this invention is to provide a pipette filter cartridge assembly device that can avoid adsorbing excess filter cartridges, prevent the production of defective products, ensure the efficiency of production work, and avoid increasing production costs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pipette filter cartridge assembly device is provided, comprising:
[0007] The storage bin and the discharge channel are configured to hold a large number of filter elements.
[0008] The vibrating receiving device is provided with a receiving port, a receiving chamber and multiple material transfer channels. The receiving port is directly opposite the discharge port of the material transfer channel. The receiving port and the receiving chamber are interconnected. All of the multiple material transfer channels are connected to the receiving chamber.

[0013] Optionally, the feeding device further includes multiple material detection elements. The feeding roller is provided with multiple through channels along the axial direction. The multiple through channels are connected to the multiple receiving grooves one by one. The through channels extend along the axial direction of the receiving grooves to the bottom wall of the receiving grooves. At the receiving position, the multiple material detection elements can pass through the multiple through channels one by one and abut against the bottom wall of the through channels.
[0014] Optionally, the feeding device further includes a rotary drive mechanism, the housing of which is disposed on the feeding platform, and the output end of which is connected to the feeding roller for driving the feeding roller to rotate in a horizontal direction.

[0016] Optionally, the vibrating material conveying device includes a material conveying platform, a second pressure plate, and a first vibrating element. The material conveying platform is provided with multiple feeding channels. The second pressure plate is pressed onto the material conveying platform. The material conveying platform is disposed on the first vibrating element. The vibrating element is used to drive the material conveying platform to vibrate, so that the filter element in the feeding channel moves along the feeding channel.
[0017] Optionally, the second pressure plate includes a first pressure plate segment and a second pressure plate segment. The first pressure plate segment is located on the side of the material transfer platform near the material transfer channel.

[0020] Optionally, the vibratory receiving device includes a vibratory plate.
[0021] The beneficial effects of this utility model are:
[0022] This invention provides a pipette filter cartridge assembly device, including a storage bin, a feeding channel, a vibrating receiving device, a vibrating conveying device, a feeding device, and a picking device. When assembling the pipette tip and filter cartridge of a pipette, a large number of filter cartridges can be fed into the storage bin. As filter cartridges are continuously added, a large number of cartridges enter the feeding channel through the outlet and fall from the outlet. Then, a large number of filter cartridges enter the receiving chamber through the receiving port of the vibrating receiving device. The vibrating receiving device then vibrates the filter cartridges in the receiving chamber, allowing the large number of filter cartridges to be arranged horizontally one by one. Under the vibration of the vibrating receiving device, the horizontally arranged filter cartridges are conveyed one by one into the conveying channel. As filter cartridges continuously enter the conveying channel, the rear filter cartridges push the front filter cartridges towards the feeding channel, thus allowing the filter cartridges to continuously enter the feeding channel. The vibrating conveying device then vibrates the filter cartridges in the feeding channel, allowing the filter cartridges to move forward sequentially along the feeding channel and continuously approach the feeding device, controlling the feeding device to roll horizontally. The roller rotates to connect the receiving groove of the feeding roller with the feeding channel, putting the feeding roller in the feeding state. As the filter element moves forward, it enters the receiving groove through the feeding channel. Then, the feeding roller is controlled to rotate 90° around the horizontal direction so that the receiving groove is vertically upward. At this time, the filter element in the receiving groove is vertically upward, that is, the axis of the filter element is vertical. Then, the picking component is controlled to move the adsorption component to directly above the limiting baffle. Then, the adsorption component is moved vertically downward so that it can pass through the through hole and extend into the receiving groove to adsorb the filter element. Then, the picking component moves the adsorption component vertically upward so that the adsorption component and the filter element pass through the through hole. Since the ratio of the diameter of the through hole to the diameter of the filter element is greater than or equal to 1 and less than 2, only a single filter element is allowed to pass through. Finally, the picking component moves the adsorption component to directly above the pipette tip for assembly.
[0023] By setting up a vibrating receiving device, a large number of filter elements can be arranged horizontally one by one in the material transfer channel and move along the extension direction of the material transfer channel. This allows the filter elements to be conveyed into the feeding channel. The vibrating material transfer device then drives the filter elements in the feeding channel to vibrate, so that the filter elements can continue to be conveyed forward to the receiving groove of the feeding roller. The vibrating receiving device and the vibrating material transfer device work together to not only convey the filter elements, but also to separate the filter elements that are stuck together by vibration, preventing the filter elements from getting stuck in the conveying path due to the burrs on their surface. By setting a limiting baffle with a through hole above the feeding roller, when the feeding roller rotates to the material picking position, the adsorption element passes through the through hole and extends into the receiving groove to adsorb the filter element. Then the adsorption element will carry the filter element through the through hole. At this time, the through hole only allows a single filter element to pass through. Therefore, it can avoid a single adsorption element adsorbing multiple filter elements at the same time for assembly work, avoid producing defective products due to adsorbing excess filter elements, ensure the efficiency of production work, and also avoid increasing production costs.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0041] This embodiment provides a pipette filter cartridge assembly device, such as... Figures 1 to 5 As shown, this can avoid adsorbing excess filter elements, prevent the production of defective products, ensure the efficiency of production work, and also avoid increasing production costs.
[0042] like Figures 1 to 3As shown, the pipette filter cartridge assembly equipment includes a storage bin 1, a feeding channel 2, a vibrating receiving device 3, a vibrating conveying device 4, a feeding device 5, and a picking device 6. The inner cavity of the storage bin 1 is connected to the feeding channel 2 via a discharge port, and the storage bin 1 is configured to hold a large number of filter cartridges. The vibrating receiving device 3 is provided with a receiving port 31, a receiving chamber 32, and multiple conveying channels 33. The receiving port 31 is directly opposite the discharge port of the feeding channel 2. The receiving port 31 is connected to the receiving chamber 32, and the multiple conveying channels 33 are all connected to the receiving chamber 32. The vibrating receiving device 3 is used to drive the filter cartridges to vibrate, so that the filter cartridges in the receiving chamber 32 are arranged laterally and conveyed into the conveying channels 33. The vibrating conveying device 4 is provided with multiple feeding channels 411, which are connected one-to-one with the multiple conveying channels 33. The feeding channel 411 can receive the filter element in the material transfer channel 33, and the vibrating material transfer device 4 can drive the filter element to vibrate so that the filter element moves along the feeding channel 411.
[0043] like Figures 1 to 3 As shown, the feeding device 5 includes a feeding platform 51, a feeding roller 52, and a limiting baffle 53. The feeding roller 52 is rotatably mounted on the feeding platform 51 in a horizontal direction. Multiple receiving grooves 521 are spaced apart along the axial direction of the feeding roller 52, extending radially along the roller. The feeding roller 52 has a receiving position and a feeding position. In the receiving position, the multiple receiving grooves 521 are connected to multiple feeding channels 411 in a one-to-one correspondence, and the receiving grooves 521 can accommodate multiple filter elements. The limiting baffle 53 is located above the feeding roller 52 and has multiple through holes 531. In the feeding position, the multiple through holes 531 are vertically aligned with the multiple receiving grooves 521, and the ratio of the diameter of the through hole 531 to the diameter of the filter element is greater than or equal to 1 and less than 2. The material handling device 6 is equipped with a material handling component 61 and multiple adsorption components 62. The material handling component 61 can move along the X, Y, and Z directions. Multiple adsorption components 62 are disposed on the material handling component 61. The adsorption components 62 can penetrate through the through hole 531 and extend into the receiving groove 521 to adsorb the filter element. The X, Y, and Z directions are perpendicular to each other.
[0044] When assembling the pipette tip and filter cartridge of the pipette, a large number of filter cartridges can be put into the storage bin 1. As filter cartridges are continuously added, a large number of filter cartridges will enter the discharge channel 2 through the discharge port and fall out of the discharge port of the discharge channel 2. Then, a large number of filter cartridges will enter the receiving chamber 32 through the receiving port 31 of the vibrating receiving device 3. Afterwards, the vibrating receiving device 3 will drive the filter cartridges in the receiving chamber 32 to vibrate, so that a large number of filter cartridges can be arranged horizontally one by one. Under the vibration of the vibrating receiving device 3, they are arranged in a certain way. The horizontally arranged filter elements are conveyed one by one into the conveying channel 33. As the filter elements continuously enter the conveying channel 33, the filter elements behind push the filter elements in front towards the feeding channel 411, thus allowing the filter elements to continuously enter the feeding channel 411. Then, the vibrating conveying device 4 will drive the filter elements in the feeding channel 411 to vibrate, so that the filter elements can move forward along the feeding channel 411 in sequence and continuously approach the feeding device 5. The feeding roller 52 is controlled to rotate horizontally, so that the feeding roller 52... The receiving trough 521 is connected to the feeding channel 411. At this time, the feeding roller 52 is in the feeding state. As the filter element moves forward, it enters the receiving trough 521 from the feeding channel 411. Then, the feeding roller is controlled to rotate 90° around the horizontal direction so that the receiving trough 521 is vertically upward. At this time, the filter element in the receiving trough 521 is vertically upward, that is, the axis of the filter element is vertical. Then, the picking component 61 is controlled to move the adsorption component 62 to directly above the limiting baffle 53. The adsorption element 62 is moved vertically downwards, allowing it to pass through the through hole 531 and extend into the receiving groove 521 to adsorb the filter element. Then, the pick-up element 61 moves the adsorption element 62 vertically upwards, allowing the adsorption element 62 and the filter element to pass through the through hole 531. Since the ratio of the diameter of the through hole 531 to the diameter of the filter element is greater than or equal to 1 and less than 2, only a single filter element is allowed to pass through. Finally, the pick-up element 61 moves the adsorption element 62 to directly above the pipette tip for assembly.
[0045] By setting up the vibrating receiving device 3, a large number of filter elements can be arranged laterally one by one in the conveying channel 33 and move along the extension direction of the conveying channel 33, so that the filter elements can be conveyed into the feeding channel 411. The vibrating conveying device 4 then drives the filter elements in the feeding channel 411 to vibrate, so that the filter elements can continue to be conveyed forward into the receiving groove 521 of the feeding roller 52. The vibrating receiving device 3 and the vibrating conveying device 4 work together to convey the filter elements and separate the sticky filter elements through vibration, preventing the filter elements from getting stuck in the conveyor due to the burrs on their surface. Within the path; by setting a limiting baffle 53 with a through hole 531 above the feeding roller 52, when the feeding roller 52 rotates to the material picking position, the adsorption element 62 passes through the through hole 531 and extends into the receiving groove 521 to adsorb the filter element. Then the adsorption element 62 will carry the filter element through the through hole 531. At this time, the through hole 531 only allows a single filter element to pass through. Therefore, it can avoid a single adsorption element 62 adsorbing multiple filter elements at the same time for assembly work, avoid producing defective products due to adsorbing excess filter elements, ensure the efficiency of production work, and also avoid increasing production costs.
[0046] For example, the vibrating receiving device 3 includes a vibrating plate.
[0047] In this embodiment, there are two storage bins 1, each with two feeding channels 2, two vibrating receiving devices 3 and two vibrating conveying devices 4. Each vibrating receiving device 3 has eight conveying channels 33 and each vibrating conveying device 4 has eight feeding channels 411. Therefore, there are 16 receiving troughs 521 and 16 through holes 531.
[0048] In other embodiments, other numbers of storage bins 1, feeding channels 2, vibrating receiving devices 3 and vibrating conveying devices 4 may be provided according to actual needs, and the number of conveying channels 33, feeding channels 411, receiving grooves 521 and through holes 531 are not limited.
[0049] Optionally, such as Figure 1 , Figure 2 and Figure 4 As shown, the feeding device 5 also includes a buffer receiving platform 54 and a pressure plate 55. The buffer receiving platform 54 is disposed between the feeding roller 52 and the vibrating conveyor 4, and the pressure plate 55 presses against the buffer receiving platform 54. The buffer receiving platform 54 is provided with multiple buffer receiving channels 541 (e.g., Figure 4 and Figure 5As shown, multiple buffer receiving channels 541 are connected to multiple feeding channels 411 in a one-to-one correspondence. In the receiving position, the end of the buffer receiving channel 541 facing away from the feeding channel 411 is connected to the receiving trough 521. Under the transmission action of the vibrating conveyor 4, the filter element in the feeding channel 411 is gradually conveyed and gradually approaches the buffer receiving platform 54. Then, the filter element in the feeding channel 411 continuously enters the buffer receiving channel 541. The filter element in the buffer receiving channel 541 will no longer vibrate, but will only move towards the feeding roller 52 under the pushing action of the rear filter element. As the rear filter element continues to push, the front filter element will gradually enter the receiving trough 521. When the filter element enters the receiving trough 521, the feeding roller 52 is controlled to rotate until the receiving trough 521 is in a vertically upward position, facilitating subsequent assembly work. By setting up a buffer receiving platform 54, the filter element moves only axially into the feeding trough, instead of entering the receiving trough 521 in a vibrating manner. Even if the feeding roller 52 rotates and the receiving trough 521 and the buffer channel are no longer connected (i.e., the feeding roller 52 no longer receives filter elements from the buffer receiving channel 541), the filter element located at the port of the buffer receiving channel 541 will not fall off due to vibration, thus avoiding material waste. In addition, by setting up a pressure plate 55, the filter element in the buffer receiving channel 541 can be vertically limited, preventing the filter element from detaching from the buffer receiving channel 541 due to excessive vibration frequency.
[0050] In this embodiment, two vibrating material conveying devices 4 are provided. Each vibrating material conveying device 4 is provided with a buffer receiving platform 54 and a pressing plate 55. Each buffer receiving platform 54 is provided with eight buffer receiving channels 541.
[0051] Optionally, such as Figures 3 to 5 As shown, the feeding device 5 also includes multiple material detection elements 56. Multiple through-channels 522 are axially arranged on the feeding roller 52, each through-channel 522 corresponding to a multiple receiving groove 521, and the through-channels 522 extend axially along the receiving groove 521 to the bottom wall of the receiving groove 521. In the receiving position, the multiple material detection elements 56 can pass through the multiple through-channels 522 and abut against the bottom wall of the through-channels 522. When conveying filter elements, the feeding roller 52 is controlled to rotate to the receiving position. At this time, the material detection elements 56 will pass through the through-channels 522 and abut against the bottom wall of the through-channels 522. The filter element will gradually move along the direction from the buffer receiving channel 541 to the receiving groove 521 and gradually enter the receiving groove 521. When the material detection element 56 detects that the filter element has reached the bottom wall of the receiving groove 521, the feeding roller 52 is controlled to rotate to the feeding position again.
[0052] It should be noted that the length between the bottom wall of the receiving trough 521 and the opening of the receiving trough 521 is greater than or equal to 2 / 3 of the filter element length and less than or equal to the filter element length.
[0053] For example, material detection component 56 includes a fiber optic sensor.
[0054] Optionally, the feeding device 5 also includes a rotary drive mechanism. The housing of the rotary drive mechanism is mounted on the feeding platform 51, and the output end of the rotary drive mechanism is connected to the feeding roller 52 for driving the feeding roller 52 to rotate in the horizontal direction. When it is necessary to rotate the feeding roller 52, simply start the rotary drive mechanism, and the output end of the rotary drive mechanism will drive the feeding roller 52 to rotate. The structure is simple and the operation is convenient.
[0055] For example, the rotary drive mechanism includes a rotary motor.
[0056] Optionally, the pipette filter cartridge assembly equipment also includes a control module, which is communicatively connected to both the material detection element 56 and the rotary drive mechanism. When conveying filter cartridges, the control module first controls the rotary drive mechanism to rotate to the receiving position, thereby connecting the receiving trough 521 with the buffer receiving channel 541. Then, the filter cartridges in the buffer receiving channel 541 are gradually conveyed into the receiving trough 521. When the material detection element 56 detects that the filter cartridge has reached the bottom wall of the receiving trough 521, it sends a signal to the control module. At this time, the control module controls the rotary drive mechanism to rotate to the loading position.
[0057] In this embodiment, the control module can also be communicatively connected to both the vibrating receiving device 3 and the vibrating transmitting device 4 to control the vibration frequency of both and the stopping or starting of their vibration.
[0058] Optionally, such as Figure 1 and Figure 2 As shown, the vibrating conveying device 4 includes a conveying platform 41, a pressure plate 42, and a vibrating element 43. The conveying platform 41 has multiple feeding channels 411, and the pressure plate 42 is pressed onto the conveying platform 41. The conveying platform 41 is mounted on the vibrating element 43, which drives the conveying platform 41 to vibrate, causing the filter element within the feeding channels 411 to move along the feeding channels 411. When the filter element is conveyed from the conveying channel 33 to the feeding channel 411 of the conveying platform 41, the vibrating element 43 drives the conveying platform 41 to vibrate, which in turn drives the filter element within the feeding channel 411 to vibrate. This allows the filter element to move along the feeding channel 411 and gradually approach the feeding device 5. Furthermore, any adhered filter elements will separate under the vibration, preventing them from getting stuck in the feeding channel 411. In addition, the pressure plate 42 is pressed on the material transfer platform 41, which can vertically limit the filter element in the feeding channel 411 and prevent the filter element from falling out of the feeding channel 411 due to excessive vibration frequency.
[0059] Preferably, the control module can also be connected to the vibrating element 43 for controlling the vibration frequency of the vibrating element 43 and the opening or closing of the vibrating element 43.
[0060] For example, vibrating element 43 includes a linear vibrating feeder.
[0061] Optionally, the pressure plate 42 includes a first pressure plate segment and a second pressure plate segment. The first pressure plate segment is located on the side of the material transfer platform 41 near the material transfer channel 33, and the second pressure plate segment is spaced apart from the first pressure plate segment. The vibrating material transfer device 4 also includes a swing plate 44, which is rotatably disposed above the first pressure plate segment in a horizontal direction and located on the side of the first pressure plate segment near the second pressure plate segment. The swing plate 44 has a first state of striking the first pressure plate segment and a second state of moving away from the first pressure plate segment. By setting the swing plate 44 to strike the first pressure plate segment, the filter element in the material transfer channel 411 can be vibrated again by striking, thereby further breaking the mechanical interlocking and adhesion of adjacent filter elements caused by burrs. This can effectively separate the adhered filter elements, avoid the jamming phenomenon caused by burrs, and provide driving force for the forward movement of the filter elements again, ensuring the smooth operation of the filter element transfer. In addition, the second pressing plate segment is spaced apart from the first pressing plate segment to avoid the swing plate 44 hitting the second pressing plate segment, and to prevent the filter element conveyed to the feeding device 5 from vibrating violently due to excessive vibration frequency, thus ensuring the smooth conveying of the filter element.
[0062] Optionally, such as Figure 1 and Figure 4 As shown, the vibratory material conveying device 4 also includes a mounting plate 45 and multiple material detection elements 2. The mounting plate 45 is positioned above the pressure plate 2 42, and the multiple material detection elements 2 are installed at intervals on the mounting plate 45. Each of the multiple material detection elements 2 corresponds to a multiple material conveying channel 33, and a material detection element 2 is installed in each material conveying channel 33. By setting the material detection elements 2, it is possible to detect whether there is a filter element in the material conveying channel 33. If a filter element is continuously detected, it indicates that the filter element conveying operation is normal, ensuring the normal progress of the assembly operation. If the material detection elements 2 do not detect a filter element in the material conveying channel 33, it indicates that the filter element conveying operation is abnormal, which can remind the staff to check and repair it in time. The mounting plate 45 provides the mounting base for the material detection elements 2.
[0063] It should be noted that if the material detection component 2 does not detect a filter element in the material transfer channel 33, it may be that the filter element put into the storage bin 1 has been completely transferred, i.e., there is a shortage of material, or it may be that the equipment is malfunctioning and needs to be repaired.
