Description

Technical Field

[0001] This utility model relates to the field of material conveying, and more specifically, to a suction gun assembly. Background Technology

[0002] In current industrial production, especially in the lithium battery manufacturing field, solvent absorption and delivery is a common and crucial step. While existing suction gun assemblies have achieved automated material absorption, they still have some shortcomings in practical applications, including: 1. Material residue issues: After absorbing material, existing suction guns often leave liquid residue on their outer walls. If there is no effective scraping mechanism during subsequent lifting and movement, this residue may drip, polluting the production environment and increasing material waste. Furthermore, the residue, after solidification, may become foreign matter, falling into the solvent and affecting product quality. 2. Lack of bottom-contact detection: Existing suction guns typically lack bottom-contact detection components. This means that when the height of the material container or tray changes slightly, the suction gun cannot accurately determine its relative position to the bottom of the container, potentially leading to insufficient or excessive insertion. The former affects the efficiency and quantity of material absorption, while the latter can damage the container or the suction gun itself, increasing equipment maintenance costs. 3. Inadequate guiding mechanism: Due to the lack of an effective guiding component, the suction gun is prone to deflection or jamming. This not only affects the normal operation of the suction gun, but may also lead to the inability to accurately insert it into the designated position of the material bucket, or cause the suction gun to interfere with other components during the lifting process, affecting the stability and safety of the entire equipment. Utility Model Content

[0003] The main objective of this invention is to provide a suction gun assembly to solve the problem of material residue on the outer wall of the suction gun in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a suction gun assembly is provided, including a base, a suction gun for suctioning materials, and a floating component. The suction gun is vertically movable relative to the base. The floating component is connected to the base, and an movable gap is formed between the floating component and the base. The floating component is sleeved on the outside of the suction gun and scrapes off the material on the outside of the suction gun when the suction gun is raised or lowered.

[0005] Furthermore, there are movable gaps between the floating assembly and the base body along both the axial and radial directions of the suction gun.

[0006] Furthermore, the suction gun assembly also includes a connector. The base has an adjustment hole. The connector is connected to the floating component and passes through the adjustment hole. There are movable gaps between the inner wall of the adjustment hole and the connector, and between the end face of the adjustment hole and the connector. The connector can be moved along the axial and radial directions of the adjustment hole.

[0007] Furthermore, the floating assembly includes a mounting flange and a scraper. The mounting flange is fitted around the periphery of the suction gun and connected to the connector. The inner periphery of the mounting flange has a mounting groove, and the scraper is disposed in the mounting groove and contacts and engages with the outer side of the suction gun.

[0008] Furthermore, the mounting flange has a central hole, the suction gun passes through the central hole, and the maximum gap between the connector and the adjustment hole is less than the maximum gap between the suction gun and the central hole.

[0009] Furthermore, the scraper is a flexible component.

[0010] Furthermore, the suction gun assembly also includes a drive unit, an intermediate transmission assembly, and a bottom-contact detection unit. The drive unit is connected to the base. The intermediate transmission assembly is located between the drive unit and the suction gun. The drive unit drives the suction gun to move up and down through the intermediate transmission assembly. The intermediate transmission assembly and the suction gun have a flexible transmission connection. When the suction gun is raised or lowered to its limit position, the intermediate transmission assembly has a free stroke relative to the suction gun. The bottom-contact detection unit is used to detect the relative positional relationship between the intermediate transmission assembly and the suction gun, and controls the drive unit to stop when there is relative movement between the suction gun and the intermediate transmission assembly.

[0011] Furthermore, the intermediate transmission assembly includes a mounting bracket and an elastic element. The mounting bracket is drivenly connected to the drive element and has a mounting cavity. The suction gun has a drive unit, which is disposed in the mounting cavity and abuts against the lower surface of the inner wall of the mounting cavity. The elastic element is disposed between the upper surface of the inner wall of the mounting cavity and the drive unit. The mounting bracket drives the drive unit to descend through the elastic element. The bottom-touching detection element is disposed between the drive unit and the mounting bracket.

[0012] Furthermore, the bottom-touching detection component includes a first detection part and a second detection part, the first detection part being disposed on the drive part and the second detection part being disposed on the mounting bracket.

[0013] Furthermore, both the mounting bracket and the drive unit have anti-rotation surfaces, which abut against each other to prevent rotation. The drive unit is anti-rotated relative to the mounting bracket through the anti-rotation surfaces.

[0014] Furthermore, the mounting bracket has a guide portion extending along the axial direction of the suction gun, and the suction gun passes through the guide portion.

[0015] By applying the technical solution of this utility model, a floating component is set up so that the suction gun can scrape off the material on the outside of the suction gun when it rises and falls, thereby reducing the material residue on the surface of the suction gun and improving work efficiency and environmental cleanliness. Specifically, on the one hand, the floating component is sleeved on the outside of the suction gun and can scrape off the material residue on the outer periphery of the suction gun, thereby preventing the material from falling and causing pollution. It can also prevent the residual material from solidifying on the outside of the suction gun and falling into the material bucket to contaminate the material inside the bucket. On the other hand, the movable gap allows the floating component to move relative to the base, thereby allowing the suction gun to have an appropriate displacement relative to the base when it rises and falls. This provides guidance for the suction gun and improves the smoothness of the suction gun's movement, thereby reducing the probability of malfunctions such as skewness and jamming of the suction gun, and thus ensuring the effectiveness and adaptability of scraping and guiding.

[0026] To address the problem of material residue on the outer wall of existing suction guns, this invention provides a suction gun assembly.

[0027] like Figures 1 to 4 The illustrated suction gun assembly includes: a base 10, a suction gun 20 for suctioning materials, and a floating component 30. The suction gun 20 is vertically adjustable relative to the base 10. The floating component 30 is connected to the base 10, and a movable gap is formed between the floating component 30 and the base 10. The floating component 30 is sleeved on the outside of the suction gun 20 and scrapes off the material on the outside of the suction gun 20 when the suction gun 20 is raised or lowered.

[0028] This embodiment, by setting a floating component 30, enables the suction gun 20 to scrape off the material on its outer side when it rises and falls, thereby reducing material residue on the surface of the suction gun 20 and improving work efficiency and environmental cleanliness. Specifically, on the one hand, the floating component 30 is sleeved on the outside of the suction gun 20, which can scrape off the material residue on the outer periphery of the suction gun 20, thereby preventing material from falling and causing pollution. It can also prevent residual material from solidifying on the outside of the suction gun 20 and falling into the material hopper to contaminate the material inside the hopper. On the other hand, the movable gap allows the floating component 30 to move relative to the base 10, thereby allowing the suction gun 20 to have an appropriate displacement relative to the base 10 when it rises and falls. This provides guidance for the suction gun 20 and improves the smoothness of its movement, thereby reducing the probability of malfunctions such as deflection and jamming of the suction gun 20, and ensuring the effectiveness and adaptability of scraping and guiding.

[0029] It should be noted that in this embodiment, the suction gun 20 is positioned above the material hopper. When the suction gun 20 is inserted into the material hopper, it can suck up the material inside. When the suction gun 20 is not in use, it can retract back above the material hopper. Of course, the device used to carry the material is not necessarily a material hopper; it can also be a tray or other devices.

[0030] In this embodiment, the floating component 30 and the base 10 have movable gaps along both the axial and radial directions of the suction gun 20. This allows the floating component 30 to float freely when the suction gun 20 rises and falls, thus avoiding jamming caused by the fixed position of the floating component 30 and ensuring the safe use of the suction gun 20. In other words, the movable gaps in this embodiment are not limited to one direction; the suction gun 20 is floating in all directions. This allows the suction gun 20 to automatically adjust within the range of movable gaps when the height of the material bucket is inconsistent or there is a slight tilt, ensuring that the suction gun 20 can accurately insert into the material bucket to pick up materials.

[0031] In this embodiment, the suction gun assembly also includes a connector 40. The base 10 has an adjustment hole. The connector 40 is connected to the floating component 30. The connector 40 passes through the adjustment hole. There are movable gaps between the inner wall of the adjustment hole and the connector 40, and between the end face of the adjustment hole and the connector 40. The connector 40 can be moved along the axial and radial directions of the adjustment hole, thereby allowing the suction gun 20 to have a certain offset space during the lifting process. This prevents jamming or wear caused by mechanical vibration or slight changes in the position of the material barrel, thereby improving the overall stability and durability of the suction gun assembly and reducing maintenance costs.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, the base 10 has a rectangular support frame, which includes a horizontally positioned upper plate, a horizontally positioned lower plate, and two vertically positioned upright plates. The two upright plates are positioned opposite each other, as are the upper and lower plates. A portion of the lower plate, together with the upper plate and the upright plates, forms a rectangular support space. Another portion of the lower plate extends to the bottom of the suction gun 20, and the lower plate has a through hole. The suction gun 20 passes through the through hole, and to prevent jamming, there is a gap between the suction gun 20 and the through hole to ensure smooth movement of the suction gun 20. An adjustment hole is also provided on the outer periphery of the through hole, and the connecting piece 40 is buoyantly positioned within the adjustment hole. Figure 4As shown, the connector 40 can be configured as a three-section structure, comprising a large-diameter section, a medium-diameter section, and a small-diameter section connected axially in sequence. The diameter of the large-diameter section is larger than the diameters of the medium-diameter section and the small-diameter section, and also larger than the diameter of the adjusting hole, to prevent the large-diameter section from entering the adjusting hole. The diameter of the medium-diameter section is larger than the diameter of the small-diameter section but smaller than the diameter of the adjusting hole. The radial clearance between the medium-diameter section and the diameter of the adjusting hole is the radial movement clearance of the floating component 30 along the suction gun 20. The small-diameter section is the part connected to the floating component 30. The small-diameter section can be connected to the floating component 30 by thread or welding, so that when the lifting direction of the suction gun 20 deviates slightly from the original lifting direction due to external factors, the suction gun 20 can move within the range of the movement clearance through the connector 40, driving the floating component 30 to move. This allows the suction gun 20 to have a certain amount of wobbling, preventing jamming during the lifting process of the suction gun 20. In this embodiment, the length of the middle diameter section of the connector 40 is greater than the length of the adjustment hole, allowing the connector 40 to move within the adjustment hole and enabling it to tilt to a certain extent within the adjustment hole, thereby allowing the suction gun 20 to tilt relative to the base 10 to a certain degree. Of course, the structure of the base support is not limited to this; it can have a horizontally extending plate with the aforementioned through hole, allowing the connector 40 to pass through the through hole.

[0033] In this embodiment, multiple connectors 40 are provided, and correspondingly, multiple adjustment holes are also provided, with each connector 40 and adjustment hole corresponding to the other. In this embodiment, three sets of connectors 40 and adjustment holes are provided, i.e., three connectors 40 and three adjustment holes are provided, arranged circumferentially on the lower plate along the suction gun 20, thereby ensuring the stability of the floating component 30. Of course, the number of connectors 40 and adjustment holes is not limited to this; it can also be set to two sets, four sets, or other quantities.

[0034] Preferably, an elastic washer is provided between the large-diameter section of the connector 40 and the surface of the lower plate. The elastic washer is sleeved on the outside of the middle-diameter section of the connector 40, thereby further preventing the large-diameter section of the connector 40 from entering the adjustment hole, thus improving the stability and reliability of the connection between the connector 40 and the seat 10. An elastic washer can also be provided between the small-diameter section and the middle-diameter section of the connector 40. The elastic washer is sleeved on the outer periphery of the connection between the small-diameter section and the middle-diameter section, so that the elastic washer is positioned between the lower plate of the seat 10 and the floating assembly 30, thereby providing the necessary movement space for the floating assembly 30 and reducing wear on the floating assembly 30. Alternatively, a compression spring can be provided between the large-diameter section of the connector 40 and the surface of the lower plate, and between the lower plate and the floating assembly 30.

[0035] Preferably, the lower plate includes a limiting sleeve 11, which forms the inner wall of the adjustment hole. The limiting sleeve 11 is a tubular structure with a circular hole in the middle portion. The two ends are bent and connected to the middle portion, forming an annular surface perpendicular to the axis of the limiting sleeve 11. The middle portion of the limiting sleeve 11 forms the inner wall of the adjustment hole, and the two ends of the limiting sleeve 11 abut against the upper and lower surfaces of the lower plate, thereby improving the strength and stability of the adjustment hole. Simultaneously, the limiting sleeve 11 is easy to replace, improving the convenience of maintenance of the adjustment hole. Optionally, the limiting sleeve 11 can be configured as an elastic element 62, which helps to mitigate the impact of the connecting member 40 on the adjustment hole, thus extending the service life of the connecting member 40. The number of limiting sleeves 11 corresponds one-to-one with the number of adjustment holes, and both are the same.

[0036] In this embodiment, the floating component 30 includes a mounting flange 31 and a scraper 32. The mounting flange 31 is fitted around the periphery of the suction gun 20 and connected to the connector 40. The inner periphery of the mounting flange 31 has a mounting groove, and the scraper 32 is disposed in the mounting groove and contacts and cooperates with the outer side of the suction gun 20, thereby enabling the scraper 32 to effectively scrape off residual material on the outer side of the suction gun 20, thus reducing the amount of residual liquid material on the outer periphery of the suction gun 20. Specifically, in this embodiment, the floating component 30 is disposed at the bottom of the suction gun 20. During the descent of the suction gun 20, the floating component 30 plays an auxiliary guiding role, ensuring that the suction gun 20 moves smoothly and without obstruction during vertical movement. The mounting flange 31 includes an upper flange 311 and a lower flange 312. Both the upper flange 311 and the lower flange 312 are flat plates, and their surfaces are perpendicular to the axis of the suction gun 20. A mounting groove is provided on the lower surface of the upper flange 311 and / or the upper surface of the lower flange 312, allowing the scraper 32 to be positioned between the upper flange 311 and the lower flange 312. Both the upper flange 311 and the lower flange 312 have a central hole through which the suction gun 20 passes. The mounting groove is located on the inner wall of the central hole, allowing the scraper 32 to be fitted onto the outside of the suction gun 20. The upper flange 311 and the lower flange 312 can be connected by connecting screws 313 or other fixing methods to ensure the stability of the connection and to reliably fix the scraper 32. In this embodiment, the connector 40 is positioned above the floating assembly 30. The small-diameter section of the connector 40 is connected to the upper flange 311. Depending on the actual situation, the connector 40 can also be positioned below the floating assembly 30, connecting to the lower flange 312. In this way, the scraper 32 is reliably fixed to the connector 40 via the mounting flange 31. The shaking of the connector 40 through the adjustment hole allows the scraper 32 to shake synchronously with the connector 40, resulting in a flexible fit between the scraper 32 and the suction gun 20. This prevents the suction gun 20 from jamming while simultaneously scraping away material from its outer side.

[0037] In this embodiment, the mounting flange 31 has a central hole, through which the suction gun 20 passes. The maximum gap between the connector 40 and the adjustment hole is smaller than the maximum gap between the suction gun 20 and the central hole, thereby preventing the connector 40 from shaking relative to the base 10 and damaging the suction gun 20. Specifically, considering that the floating component 30 is connected to the base 10, and the lifting and lowering of the suction gun 20 requires a drive component 50, and the suction gun 20 is connected to the drive component 50, in order to ensure the safety of the suction gun 20 and avoid jamming or jamming between the suction gun 20 and the floating component 30 during the lifting and lowering process, the diameter of the central hole is set to be larger than the diameter of the suction gun 20, so that the floating component 30 floats automatically relative to the suction gun 20 within a certain range, thereby allowing the suction gun 20 to have a certain degree of shaking relative to the floating component 30. Due to the existence of the movable clearance, the floating component 30 is allowed to wobble within a certain range relative to the base 10. When the gap between the suction gun 20 and the center hole is greater than the movable clearance, even if the floating component 30 moves to its limit position relative to the base 10, it can ensure that there is no jamming or jamming between the suction gun 20 and the center hole. This ensures the safety of the suction gun 20 and prevents it from being damaged by impact with the mounting flange 31. This allows the suction gun 20 to be both stable and flexible during lifting and lowering, thereby improving the adaptability of the suction gun assembly. It should be noted that the maximum gap between the connector 40 and the adjustment hole is also the maximum value of the movable clearance.

[0038] In this embodiment, the scraper 32 is a flexible component. On one hand, this allows the scraper 32 to better adapt to changes in the shape of the outer wall of the suction gun 20, ensuring a good scraping effect even if the outer surface of the suction gun 20 is slightly deformed or uneven. On the other hand, the scraper 32 protrudes from the inner wall of the central hole, allowing it to fit tightly against the suction gun 20. The flexible scraper 32 ensures the normal lifting and lowering of the suction gun 20. Optionally, the scraper 32 can be an O-ring, and the material of the scraper 32 can be EPDM or PTFE.

[0039] In this embodiment, the suction gun assembly further includes a drive component 50, an intermediate transmission component 60, and a bottom-contact detection component 70. The drive component 50 is connected to the base 10. The intermediate transmission component 60 is disposed between the drive component 50 and the suction gun 20. The drive component 50 drives the suction gun 20 to move up and down through the intermediate transmission component 60, and the intermediate transmission component 60 and the suction gun 20 have a flexible transmission connection. When the suction gun 20 is raised or lowered to its limit position, the intermediate transmission component 60 has a free stroke relative to the suction gun 20. The bottom-contact detection component 70 is used to detect the relative positional relationship between the intermediate transmission component 60 and the suction gun 20, and controls the drive component 50 to stop when there is relative movement between the suction gun 20 and the intermediate transmission component 60. In this way, through the flexible transmission of the intermediate transmission component 60 and the precise detection of the bottom-contact detection switch, it can be ensured that the suction gun 20 can stop in time when it descends to the bottom of the material bucket, avoiding damage to the material bucket or the suction gun 20 caused by excessive insertion of the suction gun 20, thereby improving the safety and accuracy of the suction gun assembly and reducing the failure rate caused by improper operation. Specifically, in this embodiment, the drive component 50 is mounted on the base 10, and can be mounted on the upright plate of the base bracket near the suction gun 20. The drive component 50 is connected to the intermediate transmission assembly 60, and the drive component 50 can drive the intermediate transmission assembly 60 to rise and fall, thereby driving the suction gun 20 to rise and fall. The flexible transmission cooperation between the intermediate transmission assembly 60 and the suction gun 20 equips the suction gun assembly with an adaptive bottom-contact detection function, enabling the suction gun 20 to achieve precise insertion in the height direction even when the height of the bucket or tray changes, while avoiding hard contact between the suction gun assembly and the bottom of the bucket or tray. The drive unit 50 lowers the suction gun 20 via the intermediate transmission assembly 60. When the suction gun 20 touches the bottom, its bottom contacts the bottom of the material container. Due to the flexible transmission between the intermediate transmission assembly 60 and the suction gun 20, the suction gun 20 cannot continue to descend, while the intermediate transmission assembly 60 continues to descend under the drive unit 50. This creates relative movement between the intermediate transmission assembly 60 and the suction gun 20, specifically the idle stroke of the intermediate transmission assembly 60 relative to the suction gun 20 when the suction gun 20 reaches its limit position. This triggers the bottom-touching detection unit 70, which then controls the drive unit 50 to stop descending, ensuring the safety of the suction gun assembly. This allows the suction gun assembly to effectively handle material containers of different heights, thereby improving its flexibility and adaptability. Optionally, the drive unit 50 can be a motor, cylinder, or similar device.

[0040] In this embodiment, the intermediate transmission assembly 60 includes a mounting bracket 61 and an elastic element 62. The mounting bracket 61 is drivenly connected to the drive element 50 and has a mounting cavity. The suction gun 20 has a drive part 21, which is disposed in the mounting cavity and abuts against the lower surface of the inner wall of the mounting cavity. The elastic element 62 is disposed between the upper surface of the inner wall of the mounting cavity and the drive part 21. The mounting bracket 61 drives the drive part 21 to descend through the elastic element 62. The bottom contact detection element 70 is disposed between the drive part 21 and the mounting bracket 61. The elasticity of the elastic element 62 is used to buffer the bottom of the suction gun 20 when it abuts against the bottom of the material barrel, thus preventing damage to the suction gun 20. At the same time, the bottom contact detection switch can detect the position change of the drive part 21 in real time, thereby ensuring that the suction gun 20 stops descending immediately when it touches the bottom, avoiding damage that may be caused by hard contact. Specifically, in this embodiment, the mounting bracket 61 is configured with a C-shaped structure, and a mounting cavity is formed inside the C-shaped structure. The mounting bracket 61 includes an upper mounting plate 612, a lower mounting plate 613, and a connecting vertical plate 614. The upper and lower connecting plates are arranged opposite each other and are both horizontally arranged. The connecting vertical plate 614 is arranged perpendicular to the upper and lower connecting plates and connects the upper and lower connecting plates. In this embodiment, the connecting vertical plate 614 is connected to the driving member 50 and rises and falls synchronously with the driving member 50. The elastic member 62 is disposed in the mounting cavity and sleeved on the outer periphery of the suction gun 20. The driving part 21 is disposed between the elastic member 62 and the lower mounting plate 613, so that the suction gun 20 stops descending when it touches the bottom. When the intermediate transmission assembly 60 continues to descend under the drive of the driving member 50, the suction gun 20 abuts against and compresses the elastic member 62, thereby changing the relative position of the intermediate transmission assembly 60 and the driving part 21, thereby triggering the bottom-touching detection member 70 and controlling the driving member 50 to stop. Optionally, the elastic element 62 can be a spring, with the compression and extension directions of the spring set along the axial direction of the suction gun 20, thereby ensuring that the suction gun 20 can move axially relative to the mounting bracket 61. Of course, the structure of the mounting bracket 61 is not limited to this; the mounting bracket 61 can also be a one-piece structure, as long as the stability of the mounting cavity is ensured.

[0041] In this embodiment, the bottom-touching detection element 70 includes a first detection part 71 and a second detection part 72. The first detection part 71 is disposed on the drive part 21, and the second detection part 72 is disposed on the mounting bracket 61. Through the interaction of the first detection part 71 and the second detection part 72, accurate detection of the bottom-touching state of the suction gun 20 is achieved. Specifically, the second detection part 72 can be disposed on the connecting plate 614 of the mounting bracket 61, and can be positioned slightly higher than the drive part 21, thus making the second detection part 72 slightly higher than the first detection part 71. When the suction gun 20 touches the bottom, and the mounting bracket 61 continues to move downwards, the second detection part 72 continues to move downwards with the mounting bracket 61, allowing the first detection part 71 and the second detection part 72 to sense each other. This enables the bottom-touching detection element 70 to quickly respond and stop the drive part 50, thereby avoiding damage to the suction gun 20 or the material container caused by detection delays or misjudgments. Of course, the arrangement of the first detection unit 71 and the second detection unit 72 is not limited to this. It can be adjusted according to the actual situation, as long as it can promptly sense the relative movement between the drive unit 21 and the mounting bracket 61 and respond quickly. Optionally, the first detection unit 71 can be configured as a detection plate, and the second detection unit 72 can be configured as a bottom-touch detection switch. When the detection plate rises relative to the second detection unit 72, the second detection unit 72 can detect the first detection unit 71 and stop the drive unit 50.

[0042] In this embodiment, both the mounting bracket 61 and the drive unit 21 have anti-rotation surfaces. These surfaces abut against each other to prevent rotation. The drive unit 21, through this anti-rotation surface relative to the mounting bracket 61, restricts the rotation of the suction gun 20 around its own axis during lifting, thereby reducing the risk of material spillage caused by the rotation of the suction gun 20 and improving operational stability. Specifically, in this embodiment, the edge of the drive unit 21 is rectangular. The surface of the drive unit 21 near the connecting plate 614 of the mounting bracket 61 is an anti-rotation surface, and the surface of the connecting plate 614 near the drive unit 21 is also an anti-rotation surface. The two anti-rotation surfaces abut against each other. Due to the rectangular shape of the drive unit 21, it cannot rotate relative to the mounting bracket 61 along the axial direction of the suction gun 20, thus preventing the suction gun 20 from rotating and ensuring the stability of the suction gun assembly. Of course, the anti-rotation surface is not limited to being a flat surface; it can also be an uneven surface with alternating concave and convex sections, ensuring that the drive unit 21 can move up and down relative to the connecting plate 614 along the axis of the suction gun 20, but cannot rotate along the axis of the suction gun 20.

[0043] In this embodiment, the mounting bracket 61 has a guide portion 611 extending axially along the suction gun 20. The suction gun 20 passes through the guide portion 611, thereby ensuring that the suction gun 20 is always positioned axially and radially by the guide portion 611. This provides reliable guidance for the suction gun 20 during both static and vertical movements, ensuring the stability and safety of the suction gun 20 during lifting and lowering. The guide portion 611 can be directly connected to the lower mounting plate 613 of the mounting bracket 61. The guide portion 611 is located on the side of the lower mounting plate 613 away from the upper mounting plate 612. The position of the guide portion 611 is fixed relative to the suction gun 20. The guide portion 611 can be configured as a cylindrical tubular structure, sleeved on the outside of the suction gun 20, and rises and falls synchronously with the suction gun 20. This reduces the shaking of the suction gun 20 during lifting and lowering, while improving the safety of the suction gun 20 and preventing it from tilting or being damaged by impacts from other components. Of course, the guide part 611 can also be connected to the upper mounting plate 612, or it can be connected to the drive component 50, which can also achieve synchronous lifting and lowering with the suction gun 20. Preferably, the guide part 611 is made of non-metallic material to avoid damaging the suction gun 20.

[0044] In this embodiment, the mounting bracket 61, connector 40, mounting flange 31, and base 10 of the suction gun assembly can all be made of metal components. It is preferable to set non-metallic isolation pads or isolation sleeves between the metal components to avoid metal friction during the movement of the suction gun assembly, thereby meeting the requirements of the lithium battery industry for metal foreign objects.

[0045] Optionally, a filter 80 can be installed at the top of the suction gun 20 to filter the material sucked up in the hopper; a one-way valve can be installed at the bottom of the suction gun 20 to prevent material backflow and ensure the quality of material conveying.

[0046] The movement process of the suction gun assembly in this embodiment is as follows: According to the instructions of the control system, the drive unit 50 drives the suction gun 20 to descend according to the set target distance. After the bottom of the suction gun 20 touches the bottom of the material barrel, the drive unit 21 on the suction gun 20 rises to compress the elastic member 62, and the corresponding first detection unit 71 rises and is sensed by the second detection unit 72. The second detection unit 72 uploads the signal to the control system, so that the suction gun 20 stops descending. According to the instructions of the control system, the suction gun 20 begins to suck up material. During this process, the filter 80 can filter impurities in the solvent process, and the outer periphery of the suction gun 20 is covered with liquid material. After the suction is completed, the suction gun 20 rises. During the rising process, the scraper 32 scrapes the liquid material on the outer periphery of the suction gun 20.

[0047] The suction gun assembly in this embodiment is equipped with a bottom-contact detection component 70, which enables precise insertion in the height direction even when the height of the hopper or tray changes, thereby preventing damage to the hopper or suction gun 20 when it descends. The guide part 611 can always maintain the radial positioning of the suction gun 20, so that the suction gun 20 has reliable guidance during both static and vertical movements, preventing the suction gun 20 from tilting and failing to be inserted into the designated position in the hopper or causing interference. The scraper 32 can reduce the residue of liquid material on the outer periphery of the suction gun 20, thereby preventing material dripping and environmental damage, and reducing the probability of residual deteriorated material falling into the hopper.

[0048] It should be noted that "multiple" in the above embodiments refers to at least two.

[0049] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0050] 1. Solved the problem of material residue on the outer wall of the suction gun;

[0051] 2. By setting up a floating component, the material on the outside of the suction gun can be scraped off when the suction gun is raised and lowered, thereby reducing the material residue on the surface of the suction gun and improving work efficiency and environmental cleanliness.

[0052] 3. The floating component is fitted on the outside of the suction gun, which can scrape off the material residue on the outer periphery of the suction gun, thereby preventing the material from falling and causing contamination. It can also prevent the residual material from solidifying on the outside of the suction gun and falling into the material hopper to contaminate the material inside. At the same time, the movable gap allows the floating component to move relative to the base, which allows the suction gun to have an appropriate displacement relative to the base when it is raised and lowered. This provides guidance for the suction gun and improves the smoothness of the suction gun's movement, thereby reducing the probability of malfunctions such as deflection and jamming of the suction gun, and thus ensuring the effectiveness and adaptability of scraping and guiding.
