Description

Technical Field

[0001] The utility model belongs to the technical field of dishwashing basket assembly equipment, and more specifically relates to an automatic loading device for upper and lower bowl baskets of a dishwasher. Background Art

[0002] With the development of science and technology and the improvement of living standards, especially the rapid development of home appliance technology, there are special dishwashing equipment for tableware cleaning. A multifunctional dishwasher generally has functions such as spraying, drying, and sterilization. Users only need to put dishes and other tableware into the dishwasher, and the dishwasher can automatically complete a series of cleaning tasks according to the user's settings. It is easy to use and fully automated, which effectively reduces the user's operation. Therefore, dishwashers are becoming more and more popular in thousands of households and are deeply loved by the majority of users.

[0003] The dish rack is an important part of the dishwasher. It is assembled in the bowl basket body. Its function is to support and fix the bowls and plates so that they can maintain a stable position during the washing process. At the same time, it can also allow the washing water and detergent to fully contact the surface of the bowls and plates to ensure thorough cleaning. The dish rack is mainly welded by a crossbeam with a turning section and a stirrup head with a ball head. In the traditional operation, manual loading is used to place the stirrup head on the crossbeam according to the specified spacing and parallelism, and then weld it. This manual operation method not only reduces work efficiency, but also cannot ensure the spacing and parallelism of the stirrup head, thus affecting the appearance of the product.

[0004] To solve the above problems, a series of automatic feeding equipment have appeared on the market. For example, the patent CN112093428A discloses a vibration plate for directional sorting and conveying of injection needle seats; the patent CN112158540A discloses a feeding device for automatic sorting and screening of lighter base plates; the patent CN107695772A discloses a pliers vibration plate vibration feeder for automatic sorting of pliers bodies; and the patent CN212314699U discloses a vibration plate that can be used for automatic sorting of nail clippers.

[0005] The above-mentioned vibration plates can realize automatic sorting and loading of workpieces, but for the stirrup head parts of the plate rack, while automatically sorting, it is also required that the placement direction of the stirrup head parts must remain consistent, that is, the ball head ends are aligned with the ball head ends, and the non-ball head ends are aligned with the non-ball head ends, so as to facilitate the subsequent grasping and welding operations.

[0040] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0041] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0042] like Figure 6 As shown, it is a schematic diagram of the structure of the stirrup head member 6 in the utility model. The stirrup head member 6 is a basic component of the rack, and it includes a rod body and a ball head located at the end of the rod body. As described in the background technology, when the stirrup head member 6 is assembled, there are certain requirements for the orientation of its ball head. This requires that after the loading is completed, the stirrup head members 6 must not only be arranged one by one in sequence, but also the orientation of the ball heads must be consistent. For this reason, the utility model aims to provide an automatic feeding device that can sort the stirrup head members 6 in the same direction and in sequence.

[0043] The utility model is further described below in conjunction with specific embodiments.

[0044] like Figure 1 As shown, an automatic loading device for upper and lower baskets of a dishwasher in this embodiment includes a frame 1, a vibration plate 2 and a first sorting mechanism 3 arranged on the frame 1. The vibration plate 2 is used to output the stirrup head pieces 6 one by one; the first sorting mechanism 3 is used to receive the stirrup head pieces 6 output by the vibration plate 2, and sort the stirrup head pieces 6 in the same direction and in sequence to meet the assembly requirements of the subsequent sequence.

[0045] It should be noted that, in this embodiment, the vibration plate 2 can be a device in the prior art, and its structure and working principle are also in the prior art, which will not be described in detail here. The first sorting mechanism 3 is the focus of this article and will be described in detail below.

[0046] refer to Figure 2 As shown, the first sorting mechanism 3 is mainly composed of two first baffles 31 arranged relatively parallel to each other. A first slideway 32 is formed between the two first baffles 31, and the width of the first slideway 32 (i.e., the spacing between the two first baffles) is greater than the rod diameter of the stirrup head 6 and smaller than the ball head diameter of the stirrup head 6, so that the rod body of the stirrup head 6 can be accommodated in the first slideway 32, and the ball head of the stirrup head 6 is located outside the first slideway 32 and supported by the top of the first baffle 31, thereby ensuring that the stirrup head 6 entering the first slideway 32 are all in a state of ball heads facing upward and distributed one by one.

[0047] In this embodiment, an automatic loading device for the upper and lower baskets of a dishwasher is provided with a first slide 32, so that the stirrup head member 6 coming out of the discharge port of the vibration plate 2 can be arranged in the same direction with the ball head facing upwards, whether in the forward direction or the reverse direction, thereby providing a good foundation for subsequent operations and making the connection between processes smoother. The forward direction here means that the ball head part of the stirrup head member 6 leaves the discharge port of the vibration plate 2 first; and the reverse direction means that the rod part of the stirrup head member 6 leaves the discharge port of the vibration plate 2 first.

[0048] In addition, it is worth mentioning that the ball head diameter mentioned above refers to the ball head diameter within the standard range, that is, the ball head diameter that meets the requirements. For some ball heads with too small diameters that do not meet the requirements, the width of the first slide 32 can be controlled, that is, the width of the first slide 32 is greater than the ball head diameter of some small diameters (depending on actual production needs), but smaller than the ball head diameter within the standard range. This design allows some small ball heads that do not meet the requirements to fall directly from the first slide 32, thereby realizing the automatic screening operation of some defective stirrup head pieces 6, which is conducive to ensuring the overall quality and appearance of the assembled product.

[0049] In this embodiment, as an implementation of the first baffle 31, the first baffle 31 is tilted as a whole to facilitate the stirrup head 6 to slide along the first slideway 32 to the discharge port of the first sorting mechanism 3 under the action of its own gravity.

[0050] Specifically, the first baffle 31 includes an inclined section, an arc-shaped transition section and a horizontal section connected in sequence. Among them, the end of the inclined section away from the horizontal section is the feed port end, and the end of the horizontal section away from the inclined section is the discharge port end. In order to facilitate the stirrup head 6 to enter the first slide 32, an inclined surface is provided on the inner side of the feed port end of the first baffle 31 (the opposite side of the two first baffles), and a guide groove 33 is formed between the inclined surfaces of the two first baffles 31. The guide groove 33 is provided at the discharge port of the vibration disk 2, so that the stirrup head 6 sorted by the vibration disk 2 can enter the first slide 32 more smoothly.

[0051] As a preferred implementation of the first sorting mechanism 3, a clamping assembly 34 is provided at the first baffle plate 31 near the discharge port end, and the clamping assembly 34 is used to squeeze from the outside of the first baffle plate 31 so that the ends of the two first baffle plates 31 are close to each other to clamp the rod body of the stirrup head member 6 to prevent the stirrup head member 6 from automatically sliding out of the first slide 32 and affecting subsequent operations.

[0052] refer to Figure 3As shown, the pressing assembly 34 includes an elastic member 341, a first connecting block 342 and a second connecting block 343. The first connecting block 342 and the second connecting block 343 are arranged on the same outer side wall of the first baffle 31, and a notch is arranged on the side of the first connecting block 342 close to the first baffle 31, and the second connecting block 343 is located in the notch.

[0053] The elastic member 341 is compressed between the inner wall of the notch and the outer wall of the second connecting block 343. Preferably, the elastic member 341 can be a compression spring. The compression spring applies an inward elastic force to the end of the first baffle 31 through the second connecting block 343, so that the first baffle 31 undergoes a certain deformation and approaches each other, and the rod body of the stirrup head member 6 can be clamped to prevent the stirrup head member 6 from sliding off from the first slideway 32.

[0054] Of course, the first slideway 32 can also be designed with a variable diameter to ensure that the stirrup head 6 can be stuck at the discharge port of the first slideway 32. However, it should be noted that whether the clamping assembly 34 or the variable diameter method is used, it is only to prevent the stirrup head 6 from naturally sliding out of the first slideway 32, but not to completely restrict the movement of the stirrup head 6. In other words, the stirrup head 6 can be restricted from sliding out freely at the discharge port of the first slideway 32, and at the same time, it is necessary to ensure that the stirrup head 6 can be taken out under the action of external force.

[0055] like Figure 2 As shown, in this embodiment, an automatic loading device for upper and lower baskets of a dishwasher is provided with a fixture 35, such as a robot, at the discharge port end of the first sorting mechanism 3, and the robot is used to take out the stirrup head member 6 in the first slide 32 and transfer it to the next process. In order to prevent the fixture 35 from interfering with the first baffle plate 31 when clamping the stirrup head member 6 in the first slide 32, an avoidance groove 311 for the fixture 35 to extend into is provided at a position near the discharge port end of the first baffle plate 31.

[0056] Preferably, the avoidance groove 311 is opened at the middle position of the first baffle plate 31, thereby dividing the end of the first baffle plate 31 into two parts, an upper and a lower part, so that the rod body part of the stirrup head piece 6 is respectively stuck in the first slide way 32 of the two parts to prevent the bottom of the stirrup head piece 6 from swinging, which is not conducive to the clamping operation of the clamp 35.

[0057] At the same time, due to the existence of the avoidance groove 311, the height of the side wall corresponding to the first baffle 31 becomes relatively small. At this time, the pressing assembly 34 is arranged on the smaller outer side wall of the first baffle 31, which is conducive to the extrusion deformation operation of this part.

[0058] As an automatic loading device for the upper and lower baskets of a dishwasher in this embodiment, a second sorting mechanism 4 is also provided on the frame 1. The second sorting mechanism 4 is used to receive the stirrup head member 6 transferred from the first sorting mechanism 3 and screen the straightness of the stirrup head member 6.

[0059] Specifically, refer to Figure 4 As shown, the second sorting mechanism 4 is located as a whole below the fixture 35, and includes two second baffles 41 placed vertically, and a second slideway 42 is formed between the two second baffles 41. The width of the second slideway 42 (the distance between the two second baffles) is slightly larger than the rod diameter of the stirrup head 6. By controlling the width of the second slideway 42, the stirrup head 6 with poor straightness can be identified and stopped online, so that it cannot pass through the second slideway 42 smoothly and is rejected, which is conducive to ensuring the quality and appearance of the final product.

[0060] In addition, a positioning fixture 5 is provided on the frame 1 for receiving the stirrup head 6 transferred from the second sorting mechanism 4. Figure 5 As shown, the positioning fixture 5 is arranged near the discharge port of the second sorting mechanism 4, and is provided with a plurality of equally spaced and parallelly distributed positioning grooves 51. The stirrup head pieces 6 in the second sorting mechanism 4 are transferred to the corresponding positioning grooves 51 by a manipulator, which can ensure that the stirrup head pieces 6 are equally spaced and arranged in parallel with each other, so as to meet the subsequent assembly requirements.

[0061] Preferably, the positioning groove 51 is a contoured groove matching the shape of the stirrup head member 6. The positioning fixture 5 can be slidably arranged on the frame 1 via a slide 52 to facilitate its transfer between different workstations.

[0062] At the same time, in order to prevent the lack of material in the positioning groove 51, which may cause defects in the later product assembly. In this embodiment, a sensor 43 is provided on the side of the positioning groove 51 to sense whether there is a lack of material in the positioning groove 51. Of course, the sensor 43 can also be provided on the second baffle plate 41 and the first baffle plate 31 to monitor the stirrup head member 6 in each slideway.

[0063] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
