Description

Technical Field

[0001] This application relates to the field of washing machines for electronic components, and in particular to a washing machine and its conveying device. Background Technology

[0002] Washing machines are used for cleaning electronic components such as semiconductors and chips. In actual production, due to the diverse materials and varying shrinkage rates of the electronic components being cleaned, warping can occur after washing and drying. When these warped components are conveyed and / or diverted on the washing machine's conveyor system, they often do not fit properly with the conveyor rollers, easily causing jamming, blockages, and / or overlapping. This disrupts the smoothness of the normal production process and poses a significant risk to the final product quality, drastically reducing the product qualification rate and increasing production costs. Utility Model Content

[0003] This application provides a washing machine and its conveying device to avoid blockage and / or stacking problems caused by warping of electronic components when they are conveyed on the conveying device of the washing machine.

[0004] To address the aforementioned technical problems, a first aspect of this application provides a conveying device for a washing machine. The conveying device includes: a group of multiple conveying rollers arranged sequentially along a first direction; and a first conveying rope and a second conveying rope. Each conveying roller includes a first contracting section and a second contracting section that gradually narrows from both sides towards the center. The first conveying rope and the second conveying rope are respectively arranged on the first contracting section and the second contracting section of the conveying roller.

[0005] To address the aforementioned technical problems, a second aspect of this application provides a washing machine. This washing machine includes a washing and drying zone, a diversion zone, and a discharge zone connected in sequence. The diversion zone includes a conveying device as described in the first aspect of this application.

[0006] The washing machine and its conveying device of this application include a first conveyor rope arranged on a first contraction section of the conveyor rollers and a second conveyor rope arranged on a second contraction section of the conveyor rollers. The first contraction section, the second contraction section, the first conveyor rope, and the second conveyor rope can cooperate with each other. The first and second contraction sections can confine warped electronic components within the conveying channel of the conveying device, while the first and second conveyor ropes can support the warped electronic components and prevent them from getting stuck between the front and rear conveyor rollers. In this way, the first contraction section, the second contraction section, the first conveyor rope, and the second conveyor rope can cooperate with each other to ensure that the warped electronic components are smoothly conveyed from one conveyor roller to the next, effectively solving the problems of jamming, blockage, and / or stacking of warped electronic components during conveying and / or diverting on the conveying device of the washing machine, improving the product qualification rate and reducing production costs.

[0012] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0013] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0014] In this article, the term "and / or" simply describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, "more" in this article means two or more objects.

[0015] The terms "first," "second," and "third" in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified in some embodiments. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indications also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0016] In related technologies, such as Figure 1 As shown, Figure 1 This diagram illustrates the structure of a warped electronic component. Washing machines are used to clean electronic components such as semiconductor devices, chips, and circuit boards. Various forms of warping may occur in electronic components after cleaning and drying. Figure 1 An electronic component is shown that, when facing upwards, arches upwards in the middle and warps downwards at both ends. The electronic component can also exhibit other warping shapes, such as bending on one side, bending in the middle, bulging in the middle, and / or combinations thereof; this application does not impose specific limitations on these. When these warped electronic components are conveyed on a transport device, their contact with the conveyor rollers is often poor, and they can become stuck between two conveyor rollers due to changes in the center of gravity, preventing them from moving normally from one conveyor roller to the next. This can cause jamming, blockages, and / or rear-end collisions and stacking on the transport device.

[0017] To address the aforementioned technical problems, this application provides a conveying device for a washing machine. (Reference) Figures 2 to 4 , Figure 2 This diagram shows a structural schematic of a transmission device 100 according to some embodiments of the present application. Figure 3 Some embodiments according to this application are shown. Figure 2 A perspective view of the conveyor roller 110 in the middle. Figure 4 Some embodiments according to this application are shown. Figure 2 A front view of the conveyor roller 110.

[0018] Figure 2The diagram illustrates a first direction X and a second direction Y. The first direction X and the second direction Y may be perpendicular to each other. The first direction X and the second direction Y may form a planar coordinate system. In this application, the first direction X and the second direction Y are used for descriptive purposes only and are not intended to limit the specific arrangement or installation orientation of the conveying device 100.

[0019] The conveying device 100 includes: a group of multiple conveying rollers 110 arranged sequentially along a first direction X; and a first conveying rope 140 and a second conveying rope 160. The first conveying rope 140 and the second conveying rope 160 may also be collectively referred to as conveying rope 130. The conveying rope 130 may have a loop shape and be configured to rotate around the group of multiple conveying rollers 110. The two sides of the multiple conveying rollers 110 in the group may be aligned to define a conveying channel. (Reference) Figures 3 to 4 Each conveyor roller 110 includes a first contraction section 1101 and a second contraction section 1102 that taper from both sides toward the center. The first contraction section 1101 and the second contraction section 1102... Figure 3 and Figure 4 The symbols are marked with curly brackets. The first conveyor rope 140 and the second conveyor rope 160 are respectively arranged on the first contraction section 1101 and the second contraction section 1102 of the conveyor roller 110. In this application, the first contraction section 1101, the second contraction section 1102, the first conveyor rope 140, and the second conveyor rope 160 can cooperate with each other. The first contraction section 1101 and the second contraction section 1102 can restrict the warped electronic components in the conveying channel of the conveying device 100, while the first conveyor rope 140 and the second conveyor rope 160 can support the warped electronic components and prevent them from getting stuck between the front and rear conveyor rollers 110. In this way, the first contraction section 1101, the second contraction section 1102, the first conveyor rope 140, and the second conveyor rope 160 can cooperate with each other to ensure that the warped electronic components are smoothly conveyed from one conveyor roller 110 to the next conveyor roller 110. This effectively solves the problems of jamming, blockage, and / or stacking of warped electronic components when they are conveyed and / or diverted on the conveyor device 100 of the washing machine, thereby improving the product qualification rate of electronic components and reducing production costs.

[0020] In some embodiments, such as Figure 2 As shown, the conveying device 100 includes multiple sets of conveying rollers 110 and multiple conveying rods 180 arranged sequentially along a first direction X. Each set of conveying rollers 110 includes multiple conveying rollers 110 arranged sequentially along the first direction X to define a conveying channel. Conveying rollers 110 from different sets and aligned with each other along a second direction Y are mounted on the same conveying rod 180 among the multiple conveying rods 180.

[0021] Specifically, multiple sets of conveyor rollers 110 are arranged side by side, forming multiple conveyor channels. The washed electronic components can be conveyed to different sets of conveyor rollers 110 to achieve diversion. Figure 2 Four sets of conveyor rollers 110 are shown. The conveyor device 100 may also include more or fewer sets of conveyor rollers 110, such as 2 sets, 3 sets, 5 sets, 6 sets, or more sets of conveyor rollers 110. Each set of conveyor rollers 110 defines a corresponding conveyor channel or conveyor flow path for conveying electronic components.

[0022] Multiple transmission rods 180 are arranged sequentially along the first direction X and are parallel to each other. For example... Figure 2 As shown, the transmission rod 180 is configured as a shaft extending along the second direction Y. The cross-section of the shaft can be circular, rectangular, or other shapes, and this application does not impose specific limitations on this. Figure 3 As shown, the conveyor roller 110 can define a mounting through hole 1105. A conveyor rod 180 can pass through the mounting through hole 1105 of the conveyor roller 110 and drive the conveyor roller 110 to rotate. The conveyor rod 180 can be connected to the corresponding conveyor roller 110, for example, via a hub connection, to drive the conveyor roller 110 to rotate. The hub connection can be, for example, a key connection, a spline connection, etc., and this application does not impose specific limitations. The conveyor roller 110 can further drive a conveyor rope 130 disposed on the conveyor roller 110 to travel, so that the conveyor rope 130 can rotate around a set of conveyor rollers 110. In this way, the conveyor roller 110 and the conveyor rope 130 can cooperate with each other under the drive of the conveyor rod 180 to convey electronic components.

[0023] like Figure 2 As shown, in the case where the conveying device 100 includes multiple sets of conveying rollers 110, the conveying rollers 110 from different sets are aligned along the second direction Y, such that the mounting through holes 1105 of these conveying rollers 110 are aligned along the second direction Y. A conveying rod 180 can be inserted through these mounting through holes 1105 aligned along the second direction Y. Figure 2 In the example shown, of the four sets of conveyor rollers 110, the first conveyor roller 110 from each set is aligned with each other along the second direction Y and is simultaneously driven by the first conveyor rod 180 passing through the mounting through hole 1105. The second conveyor roller 110 from each set is aligned with each other along the second direction Y and is simultaneously driven by the second conveyor rod 180 passing through the mounting through hole 1105, and so on, until the last conveyor roller 110.

[0024] refer to Figure 3 and Figure 4 The conveyor roller 110 may include a main body structure 1106 that smoothly expands from the center to both sides. The main body structure 1106 includes a first contracting section 1101 and a second contracting section 1102. For example... Figure 3As shown, the first contraction segment 1101 and the second contraction segment 1102 are both funnel-shaped structures. Each funnel-shaped structure includes a first end and a second end, with the diameter of the second end being larger than the diameter of the first end. The first ends of the two funnel-shaped structures are connected together to form the main structure 1106.

[0025] In this application, by providing a first contraction segment 1101 and a second contraction segment 1102, movement, especially offset, of electronic components during the transmission process can be effectively prevented. In some embodiments, the first contraction segment 1101 and the second contraction segment 1102 are symmetrically distributed. The first contraction segment 1101 and the second contraction segment 1102 can be collectively referred to as contraction segments. The contraction segment can be, for example, a cone, especially a cross-sectional cone. The upper and lower base surfaces of the cross-sectional cone are both circular. All cross-sections of the cross-sectional cone parallel to the upper or lower base surface are circular.

[0026] The generatrix of the cone surface of the cross-section cone can be a straight line, hyperbola, parabola, or elliptical arc, etc. When the generatrix is ​​a parabola or elliptical arc, the slope of the inner part of the conical contraction section is relatively gentle, while the slope of the edge part is steeper. This ensures that the electronic components being transported can more easily move automatically to the middle part of the transport roller 110 where the contraction section is located, thereby ensuring that the transport device 100 of this application has a good gathering effect on the transported electronic components.

[0027] Continue to refer to Figure 2 Along a first direction X, each group of multiple conveyor rollers 110 includes a head conveyor roller 111 at one end and a tail conveyor roller 112 at the other end. A first contraction section 1101 of the head conveyor roller 111 and a first contraction section 1101 of the tail conveyor roller 112 each define a first annular groove 1103. A second contraction section 1102 of the head conveyor roller 111 and a second contraction section 1102 of the tail conveyor roller 112 each define a second annular groove 1104. A first conveyor rope 140 is configured to be embedded in the first annular groove 1103 of the head conveyor roller 111 and the first annular groove 1103 of the tail conveyor roller 112. Similarly, a second conveyor rope 160 is configured to be embedded in the second annular groove 1104 of the head conveyor roller 111 and the second annular groove 1104 of the tail conveyor roller 112. By embedding the first conveyor rope 140 in the first annular groove 1103 and the second conveyor rope 160 in the second annular groove 1104, the head conveyor roller 111 and the tail conveyor roller 112 can limit the first conveyor rope 140 and the second conveyor rope 160 to travel substantially along the first direction X, thereby ensuring the stability and accuracy of the electronic component conveying process. At the same time, the first annular groove 1103 and the second annular groove 1104 can also increase the friction between the corresponding conveyor rope 130 and the conveyor roller 110, preventing the conveyor rope 130 from slipping on the conveyor roller 110.

[0028] In some embodiments, a first contraction section 1101 of each conveyor roller 110 defines a first annular groove 1103, and a second contraction section 1102 of each conveyor roller 110 defines a second annular groove 1104. A first conveyor rope 140 is configured to be embedded in the first annular groove 1103 of each conveyor roller 110, and a second conveyor rope 160 is configured to be embedded in the second annular groove 1104 of each conveyor roller 110.

[0029] Specifically, the term "annular groove" refers to the fact that the annular groove can be configured as a ring around the surface of the contraction section. The annular groove can be parallel to the upper or lower bottom surface of the contraction section. The cross-section of the annular groove can be rectangular, domed rectangular, trapezoidal, arc-shaped, etc., and this application does not impose any specific limitations on it.

[0030] The depths of the first annular groove 1103 and the second annular groove 1104 can be 1.0-1.5 mm, for example, 1.0 mm. The widths of the first annular groove 1103 and the second annular groove 1104 can be 2.0-2.5 mm, for example, 2.0 mm. The interval between the first annular groove 1103 and the second annular groove 1104 can be 50-55 mm, for example, 50 mm. Those skilled in the art can set the interval between the first annular groove 1103 and the second annular groove 1104 according to the size of the electronic component being conveyed. This interval is smaller than the size of the electronic component being conveyed. This ensures that normal electronic components or those with minor warping are supported by the conveyor roller 110, while severely warped electronic components can be supported by at least one conveyor rope 130 when tilted or drooping. Thus, severely warped electronic components can be conveyed from one conveyor roller 110 to the next under the support of the conveyor rope 130, preventing blockage of the electronic component conveying channel.

[0031] In some embodiments, the head conveyor roller 111 and the tail conveyor roller 112 are metal rollers, and the first conveyor rope 140 and the second conveyor rope 160 are anti-static conveyor ropes, or include an anti-static coating. In some embodiments, each conveyor roller 110 is a metal roller, and the first conveyor rope 140 and the second conveyor rope 160 are anti-static conveyor ropes, or include an anti-static coating.

[0032] Metal rollers can be made of materials such as stainless steel, aluminum alloy, or carbon steel. Metal rollers possess good structural strength and toughness, and can effectively conduct away static electricity from the conveyed electronic components, preventing static electricity buildup and damage. Similarly, anti-static conveyor ropes can effectively conduct away static electricity from the conveyed electronic components, preventing static electricity buildup and damage. Anti-static conveyor ropes may include portions formed of anti-static materials. Specifically, anti-static conveyor ropes may include at least a surface portion formed of anti-static material. The anti-static conveyor rope may also be entirely formed of anti-static material; this application does not impose specific limitations on this. Anti-static materials may include, for example, anti-static plastics with added anti-static agents, anti-static rubber with added anti-static agents, anti-static fabrics with added conductive fibers, conductive metal materials, carbon fiber materials, or any combination thereof. Anti-static agents may be, for example, hexadecyltrimethylammonium bromide, octadecyldimethylbenzylammonium chloride, alkylimidazoline, sodium dodecylbenzenesulfonate, sodium dioctylsulfosuccinate, etc.; this application does not impose specific limitations on this.

[0033] In some embodiments, the first conveyor rope 140 and the second conveyor rope 160 each include an antistatic coating. The antistatic coating may include the aforementioned antistatic material. The antistatic coating may be an outer sheath formed of antistatic fabric. The antistatic coating may also be a sheath woven from metal wires.

[0034] In some embodiments, the first conveyor rope 140 and the second conveyor rope 160 respectively include an antistatic coating layer and an elastic core. The antistatic coating layer may be, for example, an outer jacket, a sleeve, or a sheath. The antistatic coating layer may include a textured surface. The texture may be, for example, interlaced grooves, parallel grooves, or a grid pattern. The antistatic coating layer can quickly dissipate static electricity generated by friction or other reasons during operation of the conveyor rope 130 or the electronic components in contact with the conveyor rope 130, preventing static electricity accumulation. This can prevent static electricity from damaging the conveyed electronic components, reduce contamination of the conveyed electronic components due to adsorption of dust, impurities, etc., and improve the yield of the production line. The textured surface can increase the static friction force between the conveyor rope 130 and the conveyed electronic components, preventing the electronic components from slipping and moving on the conveyor rope 130, and reducing the static electricity accumulation caused by the movement of the electronic components. Textured surfaces such as interlaced grooves, parallel grooves, or a grid pattern can also facilitate the isolation of dust, impurities, etc., reducing contamination of the conveyed electronic components by the conveyor rope 130.

[0035] The elastic core can be formed, for example, from spandex fibers, polyester elastic fibers, rubber, thermoplastic elastomers, etc., and this application does not impose specific limitations on it. The elastic core can absorb the stress generated by the conveyor rope 130 during start-up, stopping, speed changes, or operation, reduce the impact force on the conveyed electronic components, better conform to the surface of the conveyed electronic components, provide uniform support and conveying force, and ensure the stability of the conveyed electronic components during the conveying process.

[0036] refer to Figure 5 , Figure 5 A schematic diagram of the structure of a washing machine 10 according to some embodiments of this application is shown. For example... Figure 5 As shown, the washing machine 10 includes a washing and drying zone 11, a diversion zone 12, and a feeding zone 13 connected in sequence. The diversion zone 12 includes the conveying device 100 described in any of the above embodiments. Figure 5 The black arrows before and after the washing machine 10 in the diagram indicate the direction of transport for the electronic components to be cleaned, dried, and diverted.

[0037] The washing machine 10 is configured to wash, dry, and / or divert electronic components such as chips and circuit boards. The electronic components can be washed and dried in the washing and drying zone 11, and then conveyed to the unloading zone 13 via the diversion zone 12.

[0038] The cleaning and drying zone 11 can clean electronic components, for example, by spraying or rinsing, to effectively remove contaminants from the electronic components. The cleaning and drying zone 11 can then dry the electronic components by hot air drying or heating drying to remove residual moisture. For example, the cleaning and drying zone 11 of the washing machine 10 conveys electronic components via a conveyor belt, and its interior can be divided into four flow channels. The cleaning and drying zone 11 alternately washes the electronic components in each flow channel.

[0039] The diversion zone 12 is configured to transfer the cleaned and dried electronic components to the corresponding unloading zone 13. The diversion zone 12 includes the components mentioned above. Figure 2-4 The conveying device 100 is described above. For example, the conveying device 100 may include four flow channels, each flow channel including eight conveying rollers 110. The conveying device 100 may also include other numbers of flow channels and conveying rollers 110, and this application does not impose specific limitations on this.

[0040] The unloading area 13 can be configured to collect and / or store electronic components conveyed from the diversion area 12. The unloading area 13 is, for example, a receiving clip, a receiving cart, etc.

[0041] In some embodiments, the washing machine 10 may further include a loading area 14. The electronic components to be cleaned can enter the cleaning and drying area 11 via the loading area 14 to complete the cleaning and drying operations.

[0042] The washing machine 10 of this application is equipped with a conveying device 100 as described above. Through the cooperation between the first shrinking section 1101, the second shrinking section 1102, the first conveying rope 140 and the second conveying rope 160, it can ensure that warped electronic components are smoothly conveyed from one conveying roller 110 to the next conveying roller 110. This effectively solves the problems of jamming, blockage and / or stacking of warped electronic components when they are conveyed and / or diverted on the conveying device 100 of the washing machine 10, thereby improving the product qualification rate and reducing production costs.
