[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0030] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] To address the problem of excessive solvent residue in the material tank in existing technologies, this invention provides a solvent feeding machine.

[0032] like Figures 1 to 9 The solvent feeding machine shown includes: a frame 10, a support member 20, a moving device 30, and a suction device 40. The support member 20 is connected to the frame 10 and has a support surface 21 for placing a material container 100. The support surface 21 is inclined relative to the horizontal plane. The moving device 30 is movably connected to the frame 10. At least a portion of the moving device 30 is inclined relative to the horizontal plane, and the inclination direction of the moving device 30 is the same as the inclination direction of the support surface 21. The suction device 40 is connected to the moving device 30 and moves synchronously with the moving device 30. The suction device 40 includes a suction gun 41, which is vertically adjustable relative to the moving device 30 so that the suction gun 41 can extend into the material container 100 to suction material.

[0033] In this embodiment, the support surface 21 is inclined relative to the horizontal plane, so that when the material bucket 100 is placed on the support surface 21, a low point is naturally formed at the bottom of the material bucket 100. Thus, when the suction gun 41 rises and falls to the low point at the bottom of the material bucket 100 to suction material, the amount of solvent residue in the material bucket 100 can be minimized, thereby significantly reducing the amount of solvent residue, improving material utilization, reducing material waste, and ultimately saving costs. Furthermore, this embodiment also includes a moving device 30, and at least a portion of the moving device 30 is in the same direction of inclination as the support surface 21. This allows the suction device 40 to move along the inclined direction of the support surface 21, so that the distance between the suction device 40 and the support surface 21 does not change when the suction device 40 is not raised or lowered. This allows the suction device 40 to be used with multiple material bins 100 in different positions, while avoiding interference or collision between the suction device 40 and the material bin 100 when it moves. After the suction device 40 is moved into place by the moving device 30, it can be raised and lowered to extend into the material bin 100. After suction is completed, it can be raised and lowered to exit the material bin 100. The whole process is highly automated and simple and convenient to operate.

[0034] It should be noted that, as Figure 1 , Figure 2 , Figure 3As shown, the support 20 of the embodiment is arranged at the lower position of the rack 10, and the moving device 30 and the material suction device 40 are arranged above the support 20, and the material barrels 100 are placed between the support 20 and the moving device 30, wherein the up-down direction is also the up-down direction in Figure 3 The support 20 can be fixed by an inclined tool or supported and fixed by a civil structure such as an inclined platform.

[0035] The material barrels 100 of the embodiment are arranged in multiple, specifically four, in a rectangular shape. Of course, the number and arrangement of the material barrels 100 can be adjusted according to actual needs, as long as the inclination angle of the support surface 21 is ensured. As shown, Figure 3 The angle between the support surface 21 and the horizontal plane is α, and the angle between a part of the moving device 30 and the horizontal plane is also α, and the size of α can be adjusted according to actual conditions. Optionally, an in-place detection member 22 can be arranged on the support 20 or the rack 10 to detect the in-place condition of the material barrel 100.

[0036] In the embodiment, the material suction device 40 further comprises a material suction lifting assembly 42, which is connected with the moving device 30 and moves synchronously, and is drivingly connected with the material suction gun 41 and drives the material suction gun 41 to lift, and the lifting direction of the material suction gun 41 is arranged vertically to the horizontal plane, so as to ensure that the material suction gun 41 can accurately extend into the low point at the bottom of the material barrel 100 to suck the material, thereby improving the precision and stability of the material suction. Specifically, as shown, Figure 4As shown, the material suction device 40 of the embodiment further has a material suction gun mounting plate, a material suction gun rack plate, and a material suction gun buffer assembly. The material suction gun mounting plate is provided in a plate shape and is vertically placed. The material suction lifting assembly 42 is connected to the moving device 30 through the material suction gun mounting plate. The material suction gun rack plate is provided at the bottom of the material suction device 40 and is connected perpendicularly to the material suction gun mounting plate, that is, the material suction gun rack plate is provided horizontally. A mounting hole for the material suction gun 41 to pass through is provided at one edge of the material suction gun rack plate, so as to provide a guiding effect for the material suction gun 41, so that the material suction gun 41 can be lifted in the vertical direction. In this way, the other edge of the material suction gun rack plate is provided with the material suction gun 41 and the material suction gun mounting plate respectively, so that space is left below the material suction gun rack plate to provide other fixing members that avoid the material suction gun 41. The material suction gun 41 is provided in a columnar structure that is vertically placed and can be lifted vertically under the driving of the material suction lifting assembly 42. The material suction gun buffer assembly is connected to the material suction gun mounting plate and the material suction gun 41, so as to ensure that the material suction gun 41 can be smoothly and gently contacted when contacting the inner wall or bottom of the material bucket 100, so as to avoid the impact force caused by hard contact from damaging the material suction gun 41, and also prevent the splashing of the solvent in the material bucket 100, so as to ensure the stability and accuracy of the material suction process. Optionally, the material suction gun buffer assembly can be provided in the form of a spring buffer, a gas pressure buffer, a damping member, etc. The material suction lifting assembly 42 can be provided in a lead screw nut system driven by a servo motor, a cylinder driving system, an electric cylinder driving system, a gear rack lifting system, etc. Of course, the structure of the material suction gun buffer assembly and the material suction lifting assembly 42 is not limited to this, and the material suction gun 41 can be smoothly and vertically lifted. It should be noted that the vertical lifting here refers to lifting in a direction perpendicular to the horizontal plane, which is different from the lifting direction perpendicular to the support surface 21. In this way, the vertical lifting of the material suction gun 41 is ensured through the material suction device 40, and the stability of the material suction process is ensured, so as to improve the accuracy and efficiency of the material suction and reduce the problem of uneven material suction caused by the inclination of the material suction gun 41. The liquid suction gun of the embodiment includes a liquid suction driving member that provides power for liquid suction. Of course, the liquid suction driving member can also be provided on the liquid suction gun mounting plate or the rack 10, and the liquid suction driving member can provide power for the liquid suction gun.

[0037] In the embodiment, the solvent feeding machine further comprises a liquid receiving tray 50 arranged below the material suction device 40, and a telescopic assembly 60 connected with the material suction device 40 and drivingly connected with the liquid receiving tray 50. The telescopic assembly 60 can drive the liquid receiving tray 50 to extend to the position directly below the material suction gun 41 and to avoid the position directly below the material suction gun 41, so that the telescopic assembly 60 controls the extension and retraction of the liquid receiving tray 50, thereby preventing solvent overflow and improving the cleanliness and safety of the production environment. Specifically, the liquid receiving tray 50 of the embodiment is arranged as a disc-shaped container with a certain volume and an upward opening to facilitate the collection of solvent that may be overflowed from the bottom of the material suction gun 41. When the material suction gun 41 is lowered for material suction, the liquid receiving tray 50 avoids the position directly below the material suction gun 41, so that the material suction gun 41 can extend into the interior of the material bucket 100 from top to bottom, avoiding collision between the liquid receiving tray 50 and the material suction gun 41. When the material suction gun 41 exits the interior of the material bucket 100 and continues to rise, the liquid receiving tray 50 extends to the position directly below the material suction gun 41 to collect solvent that may be overflowed from the material suction gun 41, thereby effectively preventing solvent overflow and preventing residual liquid from flowing into new material in the material bucket 100. The telescopic assembly 60 of the embodiment is arranged below the material suction gun bracket plate to avoid the lifting of the material suction gun 41. The telescopic assembly 60 is used to control the extension and retraction of the liquid receiving tray 50, so that the liquid receiving tray 50 can retract when the material suction gun 41 is inserted into the material bucket 100 to avoid collision with the material bucket 100, and extend when the material suction gun 41 is pulled out of the material bucket 100 to collect the residual liquid that may be dropped. The telescopic assembly 60 can adopt an electric cylinder telescopic structure, a pneumatic cylinder telescopic structure, a spring telescopic structure, etc. Of course, the liquid receiving tray 50 can also be manually pushed out or retracted, which can drive the liquid receiving tray 50 to extend and retract.

[0038] In the embodiment, the mobile device 30 further comprises a first mobile assembly 31 and a second mobile assembly 32. The first mobile assembly 31 is movably arranged on the rack 10, and the moving direction of the first mobile assembly 31 is obliquely arranged. The oblique direction of the first mobile assembly 31 is the oblique direction of the mobile device 30. The second mobile assembly 32 is movably connected with the first mobile assembly 31, and the moving direction of the second mobile assembly 32 is arranged at an angle with the moving direction of the first mobile assembly 31. The material suction device 40 is connected with the second mobile assembly 32, so that through the combined movement of the first mobile assembly 31 and the second mobile assembly 32, the precise positioning of the material suction device 40 in the three-dimensional space is realized. The oblique arrangement of the first mobile assembly 31 matches the oblique direction of the support surface 21, which can ensure the precise positioning of the material suction gun 41 in the vertical direction. The moving direction of the second mobile assembly 32 is arranged at an angle with the first mobile assembly 31, so that the material suction device 40 can move laterally in the horizontal direction, thereby realizing the material suction operation on different position material buckets 100. Figure 1 、 Figure 2As shown, the first moving assembly 31 and the second moving assembly 32 of the present embodiment are arranged in a gate structure, the first moving assembly 31 is arranged in a symmetrical structure, and the second moving assembly 32 is arranged between the symmetrical first moving assemblies 31. The second moving assembly 32 is connected with the sliders of the first moving assemblies 31 and can move as a whole along the tilting direction of the first moving assemblies 31. Meanwhile, the sliders of the first moving assemblies 31 can drive the suction gun 41 to move along a direction that forms an angle with the tilting direction of the first moving assemblies 31, so as to realize the movement of the suction gun 41 in different directions and cooperate with the material barrels 100 at different positions to suck materials.

[0039] Specifically, the rack 10 comprises a first inclined support and a second inclined support, both of which are consistent with the inclination direction of the support surface 21 and are connected with the rack 10, and the first inclined support and the second inclined support are arranged along the inclination direction of the support surface 21. The first moving assembly 31 is arranged on the inclined support, so that the moving direction of the first moving assembly 31 forms an angle α with the horizontal plane, thereby helping to reduce the amount of solvent remaining at the bottom of the material barrel 100 during the material suction process. The first moving assembly 31 can be in the form of a slider and a guide rail structure, driven by a servo motor, and the slider moves linearly along the guide rail. The mounting surface of the slider and the guide rail both form an angle α with the horizontal plane, thereby ensuring that the movement direction is parallel to the support surface 21, so as to perform operations on material barrels 100 at different positions. In this way, when the suction gun 41 moves to different positions along the first moving assembly 31 and cooperates with the material barrels 100 at different positions, it can ensure that the distance between the first moving assembly 31 and the support surface 21 is fixed, thereby ensuring that the movement path of the suction gun 41 is the same when the suction gun 41 suctions the material barrels 100 at different positions, so that the operation of the solvent feeding machine is more simple, convenient and safe. The second moving assembly 32 can be installed on the slider above the first moving assembly 31, so that the mounting surface of the second moving assembly 32 installed on the first moving assembly 31 and the mounting surface of the first moving assembly 31 installed on the second moving assembly 32 both form an angle α with the horizontal plane, thereby enabling the second moving assembly 32 as a whole to move along the inclination direction of the support surface 21. The second moving assembly 32 can be driven by a servo motor and a linear guide rail system to achieve precise movement in the horizontal direction. The movement direction of the second moving assembly 32 of the present embodiment is perpendicular to the inclination direction of the support surface 21, that is, the movement directions of the first moving assembly 31 and the second moving assembly 32 are perpendicular, thereby ensuring that the suction gun 41 can be accurately positioned above the material barrel 100 to perform material suction and other tasks. In this way, through the combined movement of the first moving assembly 31 and the second moving assembly 32, the suction device 40 can be moved above the material barrel 100, the suction gun 41 can be vertically lowered to the bottom low point of the material barrel 100 for material suction, and after the material suction is completed, the suction gun 41 can be vertically raised, which can improve the positioning accuracy and flexibility of the suction device 40, so that the solvent feeding machine can adapt to material barrels 100 at different heights and positions, thereby improving the compatibility and automation level of the equipment. Of course, the structure of the first moving assembly 31 and the second moving assembly 32 is not limited to this, as long as it can meet the movement form of the present embodiment.

[0040] In the embodiment, the solvent feeding machine further comprises a detection device 70 movably arranged relative to the frame 10, the detection device 70 comprising a visual detection device 71 and a height detection device 72, the visual detection device 71 being arranged to be liftable relative to the support surface 21 and capable of acquiring the bar code information of the bucket 100 and the state of the inner cover of the bucket 100, and the height detection device 72 being connected with the visual detection device 71 and capable of measuring the height of the bucket 100, thereby realizing automatic recognition and height detection of the bucket 100, wherein the visual detection device 71 can simultaneously consider the visual guidance and bar code recognition functions, on one hand, the visual detection device 71 can acquire the bar code information of the bucket 100, thereby recognizing the type and material information of the bucket 100, on the other hand, the visual detection device 71 can also detect the state of the inner cover of the bucket 100, to facilitate cooperation with the inner cover opening device 90 to realize the inner cover opening operation, and the height detection device 72 provides accurate positioning basis for the lifting of the material suction device 40, the visual detection device 71 and the like by measuring the height of the bucket 100. The detection device 70 of the embodiment is connected with the slider of the second moving assembly 32 and synchronously moves with the movement of the second moving assembly 32, specifically, the visual detection device 71 is connected with the slider of the second moving assembly 32, and the height detection device 72 is directly fixed on the visual detection device 71 due to its small size, of course, the height detection device 72 can also be directly fixed on the slider of the second moving assembly 32 according to the actual situation. Optionally, the visual detection device 71 can be arranged in the structure form of an industrial camera, a light source, a lens, a visual processing system and the like, and the height detection device 72 can be arranged in the form of a laser ranging sensor, an ultrasonic sensor and the like. In this way, the use of the detection device 70 can improve the automation degree and operation safety of the solvent feeding machine, ensure correct recognition of the material and correct opening of the inner cover, and at the same time, the vertical lifting position of the material suction gun 41 can be automatically adjusted according to the height of the bucket 100, thereby improving the compatibility and efficiency of the equipment.

[0041] As Figure 5As shown, in the embodiment, the detection device 70 is connected with the mobile device 30 and moves laterally under the driving of the mobile device 30, and the detection device 70 further comprises a detection lifting assembly 73, which is drivingly connected with one of the visual detection device 71 and the height detection device 72 and drives the visual detection device 71 and the height detection device 72 to synchronously lift, so as to control the lifting of the visual detection device 71 and the height detection device 72 through the detection lifting assembly 73, thereby realizing automatic identification and height detection of the material bucket 100, and improving the compatibility and efficiency of the solvent feeding machine. Specifically, the detection device 70 of the embodiment further comprises a detection mounting plate and a mounting arm, the detection mounting plate is provided in a plate shape and is vertically placed, and is used for fixing and supporting the visual detection lifting assembly 73, the mounting arm and the visual detection device 71, so as to ensure the stability of the entire visual detection device 71. The mounting arm extends from one side of the detection mounting plate, one end of which is connected with the detection mounting plate, and the other end of which is connected with the visual detection device 71, so as to ensure that the visual detection device 71 can keep stable during movement. The height detection device 72 is directly fixed on the visual detection device 71 and synchronously lifts with the visual detection device 71. The detection lifting assembly 73 can be composed of a servo motor, a linear guide rail, a sliding block and the like, and is used for adjusting the height of the visual detection device 71 and the height detection device 72, so that they can be aligned with the material bucket 100 of different heights. In this way, it can be ensured that the information of the material bucket 100 can be accurately and correctly identified and the height of the material bucket 100 can be measured before the suction operation is performed, thereby improving the automation level of the solvent feeding machine, reducing the labor intensity of the operator, and through the automatic height detection, enhancing the compatibility of the solvent feeding machine to different heights of the material bucket 100, avoiding the problems of too shallow or too deep suction caused by the change of the height of the material bucket 100, thereby improving the suction efficiency and reducing the solvent residue.

[0042] In the embodiment, the lifting direction of the detection lifting assembly 73 is vertically arranged with the support surface 21, which is different from the vertical lifting direction of the suction gun 41. Alternatively, the extension direction of the mounting arm can be parallel to the inclination direction of the support surface 21, or the setting direction of the detection mounting plate can be arranged to form an angle α with the vertical surface, so as to ensure that the lifting direction of the visual detection device 71 and the height detection device 72 is perpendicular to the support surface 21. In this way, the accurate positioning of the visual detection device 71 and the height detection device 72 in the vertical direction can be ensured, thereby improving the accuracy of identification and detection of the material bucket 100.

[0043] It should be noted that the material bucket 100 of the embodiment adopts a structure with an inner cover and an outer cover, and adopts the outer cover opening device 80 to open the outer cover and the inner cover opening device 90 to open the inner cover. When the material bucket 100 only has one kind of cover, one kind of cover opening device can be used. When the structure of the cover of the material bucket 100 does not match the inner cover opening device 90 and the outer cover opening device 80, the structure of the cutter 84 and the like can be adjusted to adapt to the cover of the material bucket 100 with different structures.

[0044] As Figure 6As shown, in the present embodiment, the solvent feeding machine further comprises an outer cover opening device 80, which comprises an outer cover opening mounting frame 81, an outer cover opening lifting assembly 82, an outer cover opening rotating assembly 83, a cutter 84 for cutting the outer cover, and an outer cover positioning member 85.

In this way, the outer cover opening device 80 can realize automatic cutting and opening of the outer cover of the material barrel 100. The outer cover opening mounting frame 81 is connected with the moving device 30, specifically connected with the slider of the second moving assembly 32, so that the outer cover opening device 80 can be driven by the moving device 30 to move transversely above the material barrel 100.

The cap opener 94 can be shaped to cooperate with the groove or edge of the inner cap of the material barrel 100, and is rotated by the inner cap opening rotating assembly 93 to unlock or lock the inner cap. The cap opener 94 needs to have sufficient strength and durability to adapt to different inner cap materials and shapes. The inner cap positioning member 95 is used for accurately positioning the position of the inner cap, to ensure that the cap opener 94 can accurately act on the inner cap. Optionally, the inner cap positioning member 95 and the outer cap positioning member 85 can adopt mechanical positioning pins, sensors or visual positioning structures, to ensure the accuracy and reliability of the cap opening operation. Of course, the structure of the inner cap opening device 90 is not unique and a jaw structure can also be adopted to open and close the inner cap. The inner cap opening lifting assembly 92 and the outer cap opening lifting assembly 82 can adopt a servo motor structure or an electric cylinder structure.

Specifically, the cap pushing-out assembly 96 is connected with the inner lid opening and lowering assembly 92, so that the cap pushing-out assembly 96 can be lowered above the inner lid under the driving of the inner lid opening and lowering assembly 92, and then the cap pushing-out assembly 96 pushes out the cap opener 94, so that the cap opener 94 can act on the inner lid. In this way, when the inner lid rotating assembly 93 rotates, the cap opener 94 can drive the inner lid to rotate, thereby realizing the locking and unlocking of the inner lid. Optionally, the cap pushing-out assembly 96 can adopt a driving system such as a pneumatic cylinder or a motor. The inner lid opening device 90 of the embodiment further comprises a cap pushing-out buffer assembly, an inner lid opening buffer device, and a suction accessory 97. The cap pushing-out buffer assembly acts on the cap pushing-out assembly 96 or the cap opener 94, so that the cap pushing-out buffer assembly can absorb the impact force during the cap pushing-out process, thereby ensuring the smoothness and safety of the operation and avoiding damage caused by the direct collision between the cap opener 94 and the inner lid. The inner lid opening buffer device is similar to the cap pushing-out buffer assembly. The inner lid opening buffer device absorbs the impact when the inner lid positioning member 95 descends to contact the inner lid of the barrel 100, thereby ensuring the accuracy of the positioning and avoiding damage to the barrel 100. As shown in FIG. 8, the suction accessory 97 can be provided as a vacuum suction cup. After the inner lid is unlocked, the vacuum suction cup adsorbs the inner lid to prevent the inner lid from falling or scattering during the removal process, thereby ensuring the cleanliness and safety of the operation. Meanwhile, after the inner lid is collected by the vacuum suction cup, the inner lid can be reinstalled on the barrel 100 by the cap opener 94 when the material in the barrel 100 is not used up.
