Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, and in particular to a wireless power supply device for sorting equipment. Background Technology

[0002] Wireless power supply technology has been widely used in automated logistics sorting systems due to its advantages such as flexibility and maintenance-free operation. In this system, electrical energy is emitted in the form of an alternating magnetic field through a transmitting coil embedded in the track. The energy is received by a pickup (receiving coil) installed on the sorting cart and converted into electrical energy, thereby driving the cart to run.

[0003] However, this magnetic field coupling-based power supply method requires a high level of cleanliness in the working environment. In actual sorting operations, especially when handling packages or mail containing metal parts (such as zippers and buttons), there is a possibility that small metal objects (such as screws, staples, and metal shavings) may loosen and fall out of the package or the equipment itself. These accidentally dropped metal objects can easily fall into the narrow gap between the pickup and the track.

[0004] Once a metallic foreign object enters this critical area, it can cause a series of serious problems: First, it may cause an electrical short circuit between the transmitting and receiving coils, leading to equipment failure or even a safety accident; second, the metallic foreign object will generate eddy current losses in a strong alternating magnetic field, resulting in local overheating, which not only wastes energy but may also burn the equipment or cause a fire hazard; third, the presence of the foreign object will interfere with the originally stable magnetic field distribution and reduce the efficiency of power transmission; fourth, larger foreign objects may cause the pickup to get stuck or scratch when sliding on the track, affecting sorting efficiency and damaging the equipment.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1

[0028] Reference Figures 1 to 6 As shown, this is the first embodiment of the present invention. This embodiment provides a wireless power supply device for sorting equipment, including an input power supply 1, a transmitter controller 11 electrically connected to the input power supply 1, a compensation capacitor 12 electrically connected to the transmitter controller 11, a track 2 electrically connected to the compensation capacitor 12, a pickup 3 slidably disposed on the track 2, a control receiver 13 electrically connected to the pickup 3, and a sorting trolley 14 electrically connected to the control receiver 13.

[0029] A shielding aluminum plate 4 has several brackets 41 fixedly connected to its upper surface, and a track 2 is installed on the top of the brackets 41.

[0030] The connecting plate 5 is installed on the upper surface of the pickup 3, and the pickup 3 is fixedly connected to the sorting cart 14 through the connecting plate 5;

[0031] A baffle 31 is fixedly connected to the top of the pickup 3 by screws, and a positioning block 32 is fixedly connected to the upper surface of the pickup 3. A positioning groove 33 is provided on the baffle 31.

[0032] It should be noted that the baffle 31 is preferably made of insulating non-magnetic material such as engineering plastic. Its width and length cover the key area of ​​the top of the pickup 3. The baffle 31 is arc-shaped. The positioning block 32 cooperates with the positioning groove 33 to ensure that the baffle 31 is accurately positioned, stable and without shaking after installation. The shielding aluminum plate 4 and the bracket 41 are electromagnetic shielding and support structures commonly used in the prior art.

[0033] When in use, the sorting trolley 14 runs along a predetermined path in the warehouse or sorting center. The input power supply 1 provides electrical energy, which is converted into high-frequency alternating current by the transmitter controller 11. After resonance compensation by the compensation capacitor 12, the power is delivered to the transmitting coil in the track 2, thereby establishing a high-frequency alternating magnetic field around the track 2. The pickup 3 installed on the sorting trolley 14 contains a receiving coil. When it slides over the track 2, the receiving coil cuts the magnetic field lines and induces a current. The induced current is rectified, regulated, and power regulated by the control receiver 13 to provide stable electrical energy for the drive motor and control system of the sorting trolley 14.

[0034] During this process, the baffle 31 acts like an "umbrella" covering the top of the pickup 3, effectively intercepting any metal or non-metal objects that accidentally fall from above, preventing them from falling directly into the precision gap between the pickup 3 and the track 2, thus avoiding potential short circuits, magnetic interference, mechanical jamming, or arc discharge. The shielding aluminum plate 4, as an existing technology structure, simultaneously performs the dual functions of supporting the track and shielding the downward diffusion of the magnetic field.

[0035] In summary, by adding a baffle 31 to the top of the pickup 3, the metal foreign objects that fall during the sorting process are effectively prevented from entering the coupling area of ​​the wireless power supply, which solves the problems that may be caused by metal foreign objects, such as short circuits, magnetic field interference, equipment jamming or electric arcing, and improves the reliability and safety of equipment operation.

[0036] like Figures 1 to 2 As shown, in a preferred embodiment, an anti-touch component 6 is provided on the lower surface of the connecting plate 5 and on one side of the pickup 3.

[0037] It should be noted that the anti-touch component 6 is located on the front / rear side of the pickup 3 in the direction of travel, and its installation position should ensure a safe distance between its lowest point and the surface of the track 2 when the sorting trolley 14 is running normally.

[0038] When in use, when the sorting cart 14 sinks, the anti-collision component 6 will act as the first line of defense, contacting the obstacle before the pickup 3.

[0039] In summary, by setting the anti-collision component 6 on the connecting plate 5, an active protection layer is added to the entire device, which solves the risk of the pickup 3 colliding directly with the track 2 due to the sinking of the trolley.

[0040] like Figures 1 to 6As shown, in a preferred embodiment, the anti-touch component 6 includes a riser 61 fixedly installed on the lower surface of the connecting plate 5, a connecting rod 62 slidably disposed on the riser 61, a pressing plate 63 fixedly connected to the top of the connecting rod 62, a limiting block 64 fixedly connected to the pressing plate 63, a tension spring 65 disposed between the pressing plate 63 and the riser 61, and a trigger switch 66 fixedly installed on the lower surface of the connecting plate 5 and located above the pressing plate 63.

[0041] The tension spring 65 always provides downward tension to the pressing plate 63, and the limiting block 64 can limit the sliding length of the connecting rod 62.

[0042] It should be noted that the signal output terminal of trigger switch 66 is connected to the emergency stop circuit of sorting cart 14.

[0043] In normal operation, the tension of the tension spring 65 is transmitted through the pressing plate 63 and the connecting rod 62, keeping the bottom end of the connecting rod 62 in its initial lowermost position. At this time, the pressing plate 63 separates from the contact of the trigger switch 66, and the system operates normally with power. When the sorting trolley 14 experiences a sinking failure, the trigger plate 67 will first contact the shielding aluminum plate 4. As the trolley sinks, the connecting rod 62 will exert an upward thrust on the trigger plate 67 under the pressure. This thrust overcomes the tension of the tension spring 65, pushing the connecting rod 62 to slide upward along the guide hole on the fixing plate 612 of the riser 61. The connecting rod 62 drives the top pressing plate 63 to move upward together. When the pressing plate 63 moves to contact and press the contact of the trigger switch 66, the trigger switch 66 instantly changes state and sends an electrical signal. This signal is immediately transmitted to the main control emergency stop circuit of the sorting trolley 14, and the control system immediately triggers emergency braking, causing the trolley to stop quickly.

[0044] In summary, through the coordinated design of the riser 61, connecting rod 62, pressing plate 63, tension spring 65 and trigger switch 66, accurate detection and rapid response to sinking faults are achieved, power can be cut off before a collision occurs, and the problem of track deformation and damage due to impact is effectively solved.

[0045] like Figure 5 As shown, in a preferred embodiment, the anti-touch component 6 further includes a trigger plate 67 fixedly installed at the bottom of the connecting rod 62, and inclined plates 68 installed on both sides of the trigger plate 67;

[0046] The ramp 68 is used to make initial contact with the surrounding structure when the sorting trolley 14 sinks unexpectedly but the sinking amount does not reach the warning position of the trigger switch 66, so as to provide initial buffering and warning.

[0047] When in use, if the trolley sinks only slightly, the pickup 3 is not in danger, but the inclined plate 68 has already interfered with the height of the guide rail 2. The two ends of the guide rail 2 will push the inclined plate 68, causing the trigger plate 67 to rise, but it does not contact the trigger switch 66.

[0048] Furthermore, support legs 69 are fixedly connected around the pressing plate 63 to prevent the trolley from falling too low and damaging the pressing plate 63, thus preventing the trigger switch 66 from being damaged.

[0049] Furthermore, the riser 61 includes a column 611 mounted on the lower surface of the connecting plate 5, and a fixing plate 612 mounted on the bottom of the column 611.

[0050] Importantly, the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
