Description

Technical Field

[0001] The present invention relates to the field of intelligent warehousing, and particularly to a method for adjusting and fixing a wire harness of a weighing component and a weighing device. Background Art

[0002] With the rise of big data and cloud services, industrial Internet technology has empowered new business scenarios in the field of intelligent warehousing, giving birth to unmanned intelligent warehousing equipment such as vending machines, intelligent AGV cars, and intelligent shelves. In the vending field, there are some intelligent devices that use weighing technology as the physical perception of material information, such as weighing cabinets and weighing shelves, which play an important role in the refined management of materials. As a key unit of weighing equipment, the weighing component / weighing module needs to be deployed in large quantities on weighing equipment to achieve refined material weighing. However, in the prior art, the weighing component has problems such as difficult installation and maintenance of components, poor anti-fooling performance, and high cost, which affect the production, assembly, and operation and maintenance efficiency. Specifically, referring to the prior art documents 1-3, the prior art problems are described as follows: When the weighing component is modularly installed into the cabinet, it is easy to cause mistakes in the wire harness direction and requires secondary disassembly, with low flexibility and fault tolerance in assembly; the method of installing the weighing component into the cabinet is complex, and the installation and fixation are carried out from an ergonomically inappropriate angle, and the degree of freedom limitation effect on the weighing component is not enough, resulting in some looseness and increasing the weighing data error; the number of components and the connection relationship are not concise enough, and the operation efficiency remains at a low level. Summary of the Invention

[0003] According to a first aspect of the present disclosure: A weighing component includes a tray (11), a sensor (12), and a chassis (13). The chassis (13) is provided with an anchor (13A) for fixing the wire harness of the sensor (12) and a wire groove (13B) for the wire harness to exit.

[0004] The wire groove is provided with a clamping portion (13B1) and a limiting portion (13B2). The wire harness is clamped into the clamping portion (13B1) and extends into the limiting portion (13B2), thereby restricting the movement degree of freedom of the wire harness in the clamping direction of the clamping portion (13B1).

[0005] In a preferred technical solution, the weighing component further includes an overload protection portion.

[0006] Preferred technical solution: The weighing assembly further includes a baffle installed on the tray (11) to restrict the position of the material or the material carrier. The baffle (14) includes vertical wall surfaces that block the material or the material carrier on three sides, namely a left wall (14A), a rear wall (14B), and a right wall (14C). The portions of the left wall (14A) and the right wall (14C) that contact the load-bearing surface are provided with a left fixing wall (14A1) and a right fixing wall (14C1), and the left fixing wall (14A1) and the right fixing wall (14C1) abut against the load-bearing surface.

[0007] Preferred technical solution: The method for fixing the baffle includes: snapping the baffle (14) into the tray from the rear of the tray;

[0008] At the front of the tray, connect the baffle (14) to the load-bearing surface of the tray (11) to completely restrict the freedom of the baffle.

[0009] According to the second aspect of the present disclosure: A method for fixing a weighing assembly module, including a weighing assembly (1), a first guiding assembly (21), and a second guiding assembly (22). The fixing method is as follows:

[0010] Adjust the position where the wire harness is snapped in according to the placement position of the weighing assembly (1);

[0011] The weighing assembly (1) is snapped into the second guiding assembly (22) under the guiding action of the first guiding assembly (21);

[0012] Implement the connection between the weighing assembly and the first guiding assembly (21).

[0013] Preferred technical solution: It further includes a step of reducing the penetration area (A1) of the wire harness slot (13B) during the snapping-in process. During the process of the weighing assembly (1) being snapped in, there is a relative offset in the pushing direction of the position of the weighing assembly (1) relative to the first guiding assembly (21), so that there is an adjustment of the penetration area (A1) determined by the wire harness slot during the offset between the wire harness slot (13B) and the guiding member (21). The penetration area can be gradually reduced during the pushing process of the weighing assembly, and the finally reduced penetration area can clamp or restrict the position of the wire harness.

[0014] Preferred technical solution: The first guiding assembly (21) is provided with an open slot corresponding to the wire harness slot (13B). During the process of the weighing assembly being snapped in, the wire harness slot and the wire harness passing direction of the open slot form an overlap, jointly forming a closed space for restricting the wire harness.

[0015] Preferred technical solution: The first guiding assembly is further provided with an abutting portion (21A) for abutting against the weighing assembly. After the abutting portion (13D) abuts against the connecting portion (13D) of the weighing assembly, they are connected.

[0016] Preferably, the second guiding component (22) is provided with a guiding portion for guiding the rear part of the weighing component to be inserted and restricting two degrees of freedom of movement perpendicular to the insertion direction of the weighing component.

[0017] According to the third aspect of the present disclosure: A weighing device includes a weighing component wire harness adjustment method, a weighing component, and a weighing component module fixing method. The weighing component is placed on a placing layer provided with a first guiding component and a second guiding component. When the weighing component, the first guiding component, and the second guiding component are cooperatively fixed, the wire harness adjustment and the weighing component module fixing method of the above technical solution are realized.

[0018] The beneficial effects achieved by the present invention are as follows: On the one hand, the present application proposes a weighing component wire harness adjustment method, which effectively solves the problems of rapid adjustment and anti-fooling of the weighing component wire harness when installed in a modular form in a container, and improves the operation efficiency.

[0019] A weighing component module fixing method and device proposed by the present application effectively solve the problems of effectively restricting the degrees of freedom of the weighing component and the installation convenience when installed in a modular form in a container.

[0020] The present application proposes a weighing device, which, while having the above two beneficial effects, effectively simplifies the number of components and connections of the weighing component, and greatly improves the installation and maintenance efficiency while enhancing the structural stability and reducing the cost.

[0033] To make the above - mentioned objects, features and advantages of the embodiments of this application more obvious and understandable, the following detailed description of the specific embodiments of this application will be given with reference to the accompanying drawings.

[0034] It should be noted that in the coordinate system XZ provided in this article, the positive direction of the X - axis represents the right side, the reverse direction of the X - axis represents the left side, the positive direction of the Z - axis represents the upper side, and the reverse direction of the Z - axis represents the lower side. At the same time, it should be noted that the terms "first", "second", etc. in the description of the present invention and the claims and the above - mentioned drawings are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order different from those illustrated or described here.

[0035] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above - mentioned terms in the present invention can be understood according to specific situations.

[0036] In the description of this specification, the descriptions referring to terms such as "embodiment", "one embodiment", and "one implementation manner" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or implementation manner are included in at least one embodiment or implementation manner of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or implementation manner. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or implementation manners.

[0037] Embodiment 1, as shown in the attached Figure 7 and 8 A weighing assembly, comprising a tray 11, a sensor 12, and a chassis 13. The chassis 13 is provided with an anchor 13A for fixing the wire harness of the sensor 12 and a wire groove 13B for the wire harness to exit.

[0038] The wire groove is provided with a clamping portion 13B1 and a limiting portion 13B2. The wire harness is clamped into the wire groove from the clamping portion 13B1 and extends into the limiting portion 13B2, thereby restricting the freedom of movement of the wire harness in the direction of being clamped into the clamping portion 13B1.

[0039] It should be noted that when the weighing assembly 1 is installed on the warehousing equipment, the wire harness is clamped into the wire groove 13B at a suitable position according to the placement position of the weighing assembly 1 in the cabinet.

[0040] The wire groove 13B is an open groove; the wire groove 13B includes a clamping portion 13B1 and a limiting portion 13B2. The wire harness is clamped from the clamping portion 13B1 of the wire groove into the limiting portion 13B2, restricting the freedom of movement of the wire harness in the direction of being clamped into the clamping portion 13B1.

[0041] In the above embodiment, the wire grooves 13B are provided on both the left and right sides of the chassis 13. After the sensor wire harness can be clamped into the wire groove from the clamping portion 13B1 without restraint, at this time, it is equivalent to the wire harness being clamped in the Z direction. At this time, the freedom of movement of the wire harness in the Y direction is restricted. Then, the wire harness is further toggled into the limiting portion 13B2. At this time, it is equivalent to the wire harness being clamped in the Y direction. At this time, the freedom of movement of the wire harness in the Z direction is restricted.

[0042] The difference between Embodiment 2 and Embodiment 1 is that the tray is provided with a tray storage space 11a, and the tray storage space 11a accommodates the head of the fastener when the weighing sensor is connected to the tray.

[0043] The tray further includes a second tray stiffening rib 112 for strengthening the stiffness of the load-bearing surface of the tray. The second tray stiffening rib 112 is arranged on both sides of the first tray stiffening rib 111.

[0044] In the above embodiments, the chassis further includes a first chassis reinforcing rib 131 for strengthening the connection strength between the chassis 13 and the sensor 12. The first chassis reinforcing rib 131 is provided with a third through-hole group 131A. The axial direction of the holes in the third through-hole group 131A corresponds to a fourth through-hole group 13B provided on the tray 13. The first chassis reinforcing rib 131 and the chassis 13 are connected to form a chassis receiving space 13a.

[0045] The chassis receiving space 13a houses the head of the fastener when the weighing sensor is connected to the chassis.

[0046] The chassis further includes a second chassis reinforcing rib 132 for strengthening the stiffness of the chassis placement surface. The second chassis reinforcing rib 132 is arranged on both sides of the first chassis reinforcing rib 131.

[0047] In some embodiments, when the hexagon socket head cap screws connect the tray and the sensor, the screw head just falls into the tray receiving space 11a between the first tray reinforcing rib 111 and the tray 11. The similar structure and purpose on the chassis are the same as those of the tray and will not be elaborated here.

[0048] The difference between Embodiment 3 and Embodiments 1 and 2 is that the weighing assembly further includes an overload protection part.

[0049] It should be noted that: by setting a height threshold, the weighing assembly is restricted from being damaged due to placing an overweight load on the tray or suddenly encountering an impact.

[0050] The overload protection part is served by the front wall surface 13C of the chassis. When the load is applied to the load-bearing surface of the tray and causes structural deformation, the front wall surface 13C first abuts against the first tray reinforcing rib 111 to achieve overload protection through a preset wall surface height.

[0051] A specific distance is set between the overload protection part and the tray for structural protection when an over-range or severely off-center load is placed on the tray. The specific distance is determined through experimental tests.

[0052] Taking a rectangular tray as an example, one specific method can be: divide the tray 11 into three equal parts in the front, middle, and rear perpendicular to the direction sensitive to force deformation (such as the cantilever direction when the weighing sensor is of the cantilever type). By placing equal-range loads at the front or rear division positions to cause the tray displacement, the distance is made less than or equal to the tray displacement.

[0053] Furthermore, as Figure 3 、 Figure 5 and Figure 7 shown, the weighing assembly further includes a connecting part 13D for abutting against the first guiding assembly 21 and implementing the connection.

[0054] In this embodiment, the connecting portion 13D is formed by the front wall surface 13C of the chassis. When the weighing assembly 1 is pushed into the first guiding assembly 21 and the second guiding assembly 22, it finally abuts against the end surface of the first guiding assembly 21. The connecting portion and the first guiding assembly 21 are respectively provided with a first connecting hole 13D1 and a second connecting hole 21A at the abutting position, and the first connecting hole 13D1 and the second connecting hole 21A are fastened by a combination screw.

[0055] The difference between Embodiment 4 and Embodiments 1 - 3 is as Figure 9 shown, the weighing assembly further includes a baffle 14 installed on the tray 11 to limit the position of the material or the material carrier. The baffle 14 includes vertical wall surfaces that block the material or the material carrier on three sides, namely a left wall 14A, a rear wall 14B, and a right wall 14C. The parts of the left wall 14A and the right wall 14C in contact with the load-bearing surface are provided with a left fixing wall 14A1 and a right fixing wall 14C1, and the left fixing wall 14A1 and the right fixing wall 14C1 abut against the load-bearing surface.

[0056] The left fixing wall 14A1 and the right fixing wall 14C1 of the baffle are respectively provided with a third connecting hole 14A11 and a fourth connecting hole 14C11. Correspondingly, the load-bearing surface of the tray is provided with a fifth connecting hole, and the third connecting hole 14A11 and the fourth connecting hole 14C11 are respectively connected to the fifth connecting hole.

[0057] The rear wall 14B of the baffle is provided with a clamping wall 14B1 corresponding to the clamping notch 114A provided on the rear wall 114 of the tray. A pair of the clamping walls 14B1 are inserted into the tray 11 to complete the buckling of the baffle 14 behind the tray 11.

[0058] Above the clamping wall 14B1, there is also a rear bending wall 14B2 for strengthening the stability of the clamping structure. The rear bending wall 14B2 can be located between the clamping walls 14B1, and the rear bending wall 14B2 abuts against the load-bearing surface.

[0059] The method for fixing the baffle is as follows:

[0060] Insert the baffle 14 from the rear of the tray;

[0061] Connect the baffle 14 with the load-bearing surface of the tray 11 at the front of the tray to completely limit the degree of freedom of the baffle.

[0062] It should be noted that: compared with the installation and disassembly principle of the baffle in the prior art, the installation or disassembly process is greatly simplified. For example, it is not necessary to disassemble the weighing assembly in advance, and the installation and disassembly can be quickly realized at the head of the weighing assembly.

[0063] The second aspect of this application is as Figure 1and Figure 2 As shown in the figure: A method for adjusting the wiring harness of a weighing component is disclosed, which includes a weighing component 1 and a sensor 12 fixed on the weighing component 1. The wire harness 121 led out by the sensor is connected to an external interface. The weighing component 1 is provided with a wire groove 13B for the sensor wire harness 121 to pass through. The wire harness adjustment method includes:

[0064] Fix a part of the wire harness between the lead-out end of the sensor wire harness and the end of the wire harness in advance, leaving a part of the free wire harness unconstrained;

[0065] According to the required placement position of the weighing component 1, select a wire groove 13B that matches the position to snap in the free wire harness to adjust the outlet direction of the free wire harness and the position where the wire harness is snapped in.

[0066] It should be noted that: The weighing component 1 is arranged on a warehousing device with multiple compartments distributed. The wire harnesses between adjacent compartments converge in the same wiring space. In this case, it is required that the wire harnesses of the weighing components 1 placed in adjacent compartments exit in the most favorable direction for each other. For example, in the case of corresponding left and right compartments, the outlet direction of the wire harness of the weighing component 1 is not determined in advance. The user directly adjusts the outlet direction of the wire harness according to the placement position of the weighing component 1. For example, when placed in the left compartment, the wire harness can be adjusted to the right wire groove. The same principle applies to the weighing component 1 placed in the right compartment position. In this layout, it allows the wire harness to complete the convergence between the left and right compartments under rapid adjustment. Compared with the existing method, the improvement of the adjustment method effectively improves the flexibility and assembly efficiency of the wire harness, and completely avoids the problem of poor anti-fooling caused by pre-determining the wire harness.

[0067] The third aspect disclosed in this application: As Figure 3 、 Figure 4 and Figure 7 As shown in the figure: A method for fixing a weighing component module, including a weighing component 1, a first guiding component 21, and a second guiding component 22. The fixing method is as follows:

[0068] Adjust the position where the wire harness is snapped in according to the placement position of the weighing component 1;

[0069] The weighing component 1 is snapped into the second guiding component 22 under the guiding action of the first guiding component 21;

[0070] Implement the connection between the weighing component and the first guiding component 21.

[0071] It should be noted that: it also includes a step of reducing the penetration area A1 of the wire slot 13B during the process of snapping in the wire harness. During the process of the weighing assembly 1 being snapped in, there is a relative offset in the pushing direction of the position of the weighing assembly 1 relative to the first guiding assembly 21, so that there is an adjustment of the penetration area A1 determined by the wire slot 13B and the guiding member 21 during the offset process. The penetration area can be gradually reduced during the process of the weighing assembly being pushed in, and the finally reduced penetration area can clamp or limit the position of the wire harness.

[0072] The first guiding assembly 21 is provided with an open slot corresponding to the wire slot 13B. During the process of the weighing assembly being snapped in, the wire slot and the wire passing direction of the open slot form an overlap, jointly forming a closed space for restricting the wire harness.

[0073] In a preferred technical solution, the first guiding assembly is further provided with an abutting portion (21A) for abutting against the weighing assembly. After the abutting portion (13D) abuts against the connecting portion (13D) of the weighing assembly, they are connected.

[0074] In a preferred technical solution, the second guiding assembly (22) is provided with a guiding portion for guiding the rear part of the weighing assembly to be snapped in and restricting two degrees of freedom of movement perpendicular to the direction of the weighing assembly being snapped in.

[0075] It should be noted that: refer to Figure 3 、 4 As shown in FIGS. 5, etc., the weighing assembly 1 is pushed in from the outside of the device to the inside under the guiding action of the guiding member 21, for example, from outside the cell to the inside of the cell. During this process, the guiding member 21 has a notch allowing the wire harness to pass through. The penetration area of this notch and the penetration area of the wire slot have an overlapping part during the process of the weighing assembly 1 being pushed in, and this overlap gradually becomes smaller to a determined value during the process of the weighing assembly being snapped in. In some embodiments, the overlapping penetration cross-section is a closed rectangle, and at least the length dimensions of the opposite sides are smaller than the diameter of the wire harness. During the process of the weighing assembly 1 being snapped in, the reduction of the overlapping part allows a section of the wire harness in the overlapping part to be clamped by the first guiding member 21 and the weighing assembly 1.

[0076] In an embodiment, when the second guiding component 22 is used to push the weighing component 1 into the device from the outside of the device (in the Y direction), it guides and positions the inner part of the weighing component 1 inside the device. The second guiding component 22 includes two positioning pins 221 for guiding and inserting into the weighing component 1. When the weighing component 1 is pushed into the action range of the positioning pins 221, the weighing component 1 is allowed to abut against the root of the positioning pins 221 and the substrate 222 for fixing the positioning pins under the guiding action of the positioning pins 221, thereby effectively positioning the weighing component 1 inside the device. At this time, under the action of the first guiding component 21 and the second guiding component 22, the weighing component 1 is restricted in the X, Z translational degrees of freedom and the X, Y, Z rotational degrees of freedom.

[0077] Under the guiding action of two symmetric guiding members on the left and right, all the processes of installing the weighing component in the above embodiment can be realized according to different wire outlet directions.

[0078] Compared with the prior art, the above implementation method reduces the number of wire harness anchorings and effectively avoids the influence of the wire harness on the effective weighing sensitive area (such as the tray) of the weighing component 1.

[0079] According to the fourth aspect of the present disclosure: A weighing device includes a weighing component wire harness adjustment method, a weighing component, and a weighing component module fixing method, the weighing component, and a placement layer for placing the weighing component. The placement layer is provided with a first guiding component and a second guiding component. When the weighing component, the first guiding component, and the second guiding component are cooperatively fixed, the wire harness adjustment and the weighing component module fixing method of the above technical solution are realized.

[0080] The present invention solves the problems that when the weighing component is modularly installed in the container, it is easy to cause mistakes in the wire harness direction and requires secondary disassembly, and the flexibility and fault tolerance of assembly are low; the method of installing the weighing component in the container is simple, and the installation and fixation are carried out from the ergonomic angle, and the effect of restricting the degrees of freedom of the weighing component is increased, thereby improving the accuracy of weighing data; the number of components and the connection relationship are relatively streamlined, and the operation efficiency is maintained and improved.

[0081] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
