Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a charging device for a rail-mounted robot. Background Technology

[0002] Currently, rail-mounted robot charging equipment generally uses inductive wireless charging, which utilizes the principle of electromagnetic induction to achieve power transmission through magnetic field coupling between the charging platform and the robot. This method offers advantages such as high convenience and reduced physical connections.

[0003] However, the speed of a track-mounted robot is affected by various factors during its movement, including track slope, load, and control system response time. Therefore, the robot's speed is not constant when approaching the charging device. Inductive wireless charging relies on precise docking and relative positioning between the robot and the charging device. Consequently, in existing technologies, track-mounted robots cannot stop at the designated charging location, and the inductive charging system cannot establish stable electromagnetic coupling. This leads to charging failure or significantly reduced charging efficiency, ultimately resulting in charging failure and affecting the stability and reliability of the entire charging process. Consequently, precise stopping is impossible.

[0004] Therefore, existing technologies have shortcomings and need to be improved and developed. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art to which this invention pertains.

[0030] The terms "first," "second," and similar words used in the specification and claims of this patent application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, unless the context clearly indicates otherwise, the singular forms of "an," "a," or "the," etc., do not indicate a quantity limitation, but rather indicate the presence of at least one. Terms such as "comprising" or "including" mean that the element or object preceding "comprising" encompasses the features, integrals, steps, operations, elements, and / or components listed following "comprising" or "including," and do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or collections thereof. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0031] In existing technologies, the moving speed of the track-mounted robot approaching the charging device is not constant, so the track-mounted robot cannot stop at the charging position. The inductive charging system cannot establish a stable electromagnetic coupling, which leads to the charging process failing to start or the charging efficiency being greatly reduced, ultimately resulting in charging failure, thus affecting the stability and reliability of the entire charging process.

[0032] Therefore, this utility model embodiment provides a charging device for a rail-mounted robot, referring to... Figures 1-3 The system includes a guide rail 1, one end of which is detachably connected to a charging component. A rail-mounted robot 2 is slidably connected to the guide rail 1, and an RFID antenna 201 is detachably connected to the rail-mounted robot 2. When viewed from above, the RFID antenna 201 is projected onto the surface of the guide rail 1. A first stop block 202 and a first limit switch 203 are also detachably connected to the rail-mounted robot 2. A first support plate 3 is detachably connected to the surface of the guide rail 1, and an RFID card 4 is detachably connected to the first support plate 3. The height of the RFID card 4 is the same as the height of the RFID tag.

[0033] The charging assembly includes a second support plate 5, which is detachably connected to the rail surface of the guide rail 1. A wireless charging transmitting coil 6 is detachably connected to the second support plate 5 and electrically connected to a power source. A power disconnect device is electrically connected between the power source and the wireless charging transmitting coil 6. The power source is an external, independent device designed to supply power to the wireless charging transmitting coil 6. The height of the wireless charging transmitting coil 6 is the same as the height of the wireless charging receiving coil 204 of the rail-mounted robot 2. The second support plate 5 is also detachably connected to a second stop 7 and a second limit switch 8. The second stop 7 and the first limit switch 203 are located on a straight line parallel to the guide rail 1, with the lowest surface of the second stop 7 lower than the highest surface of the first limit switch 203. The second limit switch 8 and the first stop 202 are located on a straight line parallel to the guide rail 1, with the lowest surface of the second limit switch 8 lower than the highest surface of the first stop 202. When the second stop 7 contacts the first limit switch 203 to output a signal to the rail-mounted robot 2, causing the rail-mounted robot 2 to stop, the first stop 7 simultaneously contacts the second limit switch 8 to output a signal to the power-off device, causing the power-off device to supply power to the wireless charging transmitting coil 6 after a delay. After the wireless charging transmitting coil 6 is energized, it senses the wireless charging receiving coil 204 and can start charging the rail-mounted robot 2.

[0034] The robot stops and charges via a sliding connection between the track-mounted robot 2 and the guide rail 1, positioning via the RFID antenna 201 and the RFID card 4, and wireless charging via the wireless charging transmitting coil 6 and the wireless charging receiving coil 204. A power-off device controls the wireless charging to ensure safety and facilitate successful charging of the track-mounted robot 2. A second limit switch 8 is connected to the power-off device, which is positioned between the power supply and the wireless charging transmitting coil 6 to control the power-on time of the wireless charging transmitting coil 6. When the track-mounted robot 2 stops on the guide rail 1, the second stop 7 contacts the first limit switch 203, which outputs an I / O signal to stop the robot 2. During this process, the first stop 202 and the second limit switch 8 simultaneously contact each other, and the second limit switch 8 outputs an I / O signal to the power-off device. After a delay of several seconds, the power supply is restored to the wireless charging transmitting coil 6, enabling wireless charging of the track-mounted robot 2. When the track-mounted robot 2 finishes charging and leaves, the first stop 202 disengages from the second limit switch 8, the power-off device immediately cuts off power, the second stop 7 disengages from the first limit switch 203, and the track-mounted robot 2 continues to move. The limit switches and stops ensure the robot stops in the correct position, avoiding incorrect wireless charging starts due to inaccurate positioning or external interference. The positioning of the RFID antenna 201 and RFID card 4 improves the accuracy of the charging process. When the track-mounted robot 2 is charging, it needs to pass over the RFID card 4. After the RFID antenna 201 reads the RFID card 4, the speed of the track-mounted robot 2 changes, allowing it to stop smoothly at the charging component position. Compared with existing technologies, the use of RFID technology, limit switches, and stops provides more precise and stable charging control.

[0035] In some embodiments, when the rail-mounted robot 2 is slidably connected to the guide rail 1, it is divided into a first body 205 and a second body 206 by the guide rail 1, with the first surface of the first body 205 facing the second surface of the second body 206; the RFID antenna 201 is threaded to the first surface, the first stop 202 is threaded to the first surface, and the first limit switch 203 is threaded to the second surface.

[0036] The RFID antenna 201 and the first stop 202 are threadedly connected to the first surface, and the first limit switch 203 is threadedly connected to the second surface. The threaded connection allows the RFID antenna 201, the first stop 202, and the first limit switch 203 to adjust their angle, position, height, etc., according to different models of the rail-mounted robot 2.

[0037] The charging assembly also includes a first connector 9, a second connector 10, and a third connector 11. The direction in which the rail-mounted robot 2 moves along the guide rail 1 is defined as forward. The first connector 9 is located on the left side of the second support plate 5, and the second connector 10 is located on the right side of the second support plate 5. The first connector 9 and the second connector 10 are detachably connected to the second support plate 5 by bolts. The space formed by the second support plate 5 and the second connector 10 is used to accommodate the first main body 205. The third connector 11 is detachably connected to the first connector 9 on the same side of the second support plate 5 by bolts.

[0038] The first connecting member 9, the second connecting member 10, and the third connecting member 11 are designed to install the second stop 7, which is adapted to the first limit switch 203, and the second limit switch 8, which is adapted to the first stop 202. They are detachably connected by bolts, allowing the second stop 7 and the second limit switch 8 to be adaptively adjusted according to the angle, position, and height of the first stop 202 and the first limit switch 203. The second connecting member 10 and the third connecting member 11 are flat plates with holes for bolts to pass through.

[0039] The second connector 10 includes, from left to right, a first extension, a second extension, and a third extension. The first extension is parallel to the rail surface of the guide rail 1. The bottom surface of the second extension forms an obtuse angle with the first extension. The third extension is perpendicular to the rail surface of the guide rail 1. A second stop 7 is threaded onto the first extension. A wireless charging transmitting coil 6 is threaded onto the third extension. When the rail-mounted robot 2 is charging, the wireless charging transmitting coil 6 is directly facing the wireless charging receiving coil 204. A second limit switch 8 is threaded onto the third connector 11.

[0040] By designing the first extension, the second extension, and the third extension, space is provided for charging the rail-mounted robot 2, which facilitates the contact between the first limit switch 203 and the second stop 7, and the contact between the second limit switch 8 and the first stop 202.

[0041] In some embodiments, reference is made to Figure 4 The first limit switch 203 includes a first connecting seat 2031, a first rotating shaft 2032, and a first rotating wheel 2033. The connecting seat is detachably connected to a first surface. One end of the first rotating shaft 2032 is rotatably connected to the connecting seat, and the other end of the first rotating shaft 2032 is rotatably connected to the first rotating wheel 2033. (Refer to...) Figure 5 The second stop 7 includes, from top to bottom, an adjusting part 701 and a receiving part 702. The adjusting part 701 is detachably connected to the first extension. The receiving part 702 is an inverted isosceles trapezoid. The waist side of the receiving part 702 is used to receive the first rotating wheel 2033. The shorter side of the parallel opposite sides of the receiving part 702 is lower than the highest point of the first rotating wheel 2033.

[0042] The design incorporates a first limit switch 203 and a second stop block 7. The first rotating wheel 2033 can slide on the side of the receiving part 702, and the first rotating shaft 2032 can rotate. When the first rotating wheel 2033 slides on the receiving part 702, the rotation of the first rotating shaft 2032 prevents it from affecting the speed of the rail-mounted robot 2, thereby improving the alignment accuracy of the rail-mounted robot 2 during charging. The introduction of the linkage between the first rotating shaft 2032 and the first rotating wheel 2033 makes the triggering of the first limit switch 203 more stable and reliable, reducing wear and improving durability compared to traditional mechanical structures.

[0043] In some embodiments, reference is made to Figure 5 The second stop 7 also includes a bending portion 703, which includes a first bending surface and a second bending surface. The first bending surface is attached to the upper surface of the first extension and is connected to the first extension by a bolt thread. The first extension has a hole that passes through it, and the adjusting portion 701 is inserted into the hole. The second bending surface is perpendicular to the upper surface of the first extension, and the adjusting portion 701 has a long slot. The adjusting portion 701 is connected to the second bending surface by a bolt thread inserted into the long slot.

[0044] The second stop 7, with its bending section 703, allows for easy position adjustment. The detachable design of the adjustment section 701 provides flexibility, allowing for vertical adjustment of the second stop 7 as needed, ensuring smooth contact with the first limit switch 203 and triggering the correct signal when the robot stops. The bending section 703 design achieves a more stable adjustment method for the second stop 7. Furthermore, the combination of the adjustment section 701 and the bending surface allows the charging equipment to adapt to the parking requirements of different rail-mounted robots 2, improving the adjustability and adaptability of the equipment.

[0045] In some embodiments, a rubber ring is fitted on the outer contour of the first rotating wheel 2033.

[0046] A rubber ring is fitted around the outer contour of the first rotating wheel 2033 to enhance contact and ensure more precise operation of the limit switch. The rubber ring design makes the contact between the rotating wheel and the stop block smoother, reducing misoperation caused by vibration or impact. It also reduces operational inaccuracies due to wear, making the mechanical system more precise and stable, and extending the service life of the equipment.

[0047] In some embodiments, the hole is a long slot.

[0048] The hole is designed so that the adjusting bolt can move the second stop 7 left and right more flexibly and adjust it. The relative position of the second stop 7 can be adjusted according to actual needs to match the first limit switch 203, which improves the adaptability and operability of the charging system.

[0049] In some embodiments, reference is made to Figure 6 The second limit switch 8 includes a second connecting seat 801, a second rotating shaft 802, a rotating rod 803, and a second rotating wheel 804. One end of the third connecting member 11 is threadedly connected to the first connecting member 9 by a bolt. The second connecting seat 801 is threadedly connected to the third connecting member 11 by a bolt. The second rotating shaft 802 is rotatably connected to the second connecting seat 801, and the axis of the second rotating shaft 802 is perpendicular to the second connecting seat 801. The end of the second rotating shaft 802 not connected to the third connecting seat is fixed with the rotating rod 803. The end of the rotating rod 803 not connected to the second rotating shaft 802 is rotatably connected to the second rotating wheel 804. The first stop 202 is an isosceles trapezoid. The waist side of the first stop 202 is used to support the second rotating wheel 804. The shorter side of the parallel opposite sides of the second stop 7 is higher than the lowest point of the second rotating wheel 804.

[0050] The design incorporates a second limit switch 8 and a first stop block 202. The second rotating wheel 804 can rotate freely. After the second rotating wheel 804 deflects, the rotating rod 803 rotates, thereby driving the second rotating shaft 802 to rotate. The second rotating wheel 804 can rotate freely and can also be pushed and slid off the side by the first stop block 202. Because the second rotating shaft 802 can rotate, when the second rotating wheel 804 slides on the first stop block 202, the rotation of the second rotating shaft 802 prevents it from affecting the speed of the rail-mounted robot 2, thus improving the alignment accuracy of the rail-mounted robot 2 during charging. The introduction of the linkage between the second rotating shaft 802 and the second rotating wheel 804 makes the triggering of the second limit switch 8 more stable and reliable, reducing wear and improving durability compared to traditional mechanical structures.

[0051] In some embodiments, reference is made to Figures 1-3 The second connecting seat 801 has an elongated slot, and the third connecting seat is threadedly connected to the second connecting seat 801 by a bolt inserted into the elongated slot.

[0052] The overall design incorporates a long slot, and the adjusting bolts allow the third connector to move back and forth more flexibly. The relative position of the third connector can be adjusted according to actual needs to match the first stop 202 and the second limit switch 8. The contact between the first stop 202 and the second limit switch 8, and between the second stop 7 and the first limit switch 203, occurs simultaneously, thereby improving charging accuracy.

[0053] In some embodiments, a rubber ring is fitted onto the outer contour of the second rotating wheel 804.

[0054] Similar to the first rotary wheel 2033, the second rotary wheel 804 has a rubber ring fitted around its outer contour to enhance contact and ensure more precise operation of the limit switch. The rubber ring design makes the contact between the rotary wheel and the stop block smoother, reducing misoperation caused by vibration or impact. This reduces operational inaccuracies due to wear, making the mechanical system more precise and stable, and extending the service life of the equipment.

[0055] In some embodiments, a slot is provided through the second extension.

[0056] By designing a slot that runs through the second extension, this slot is used as an observation window to observe the contact between the first limit switch 203 and the second stop 7, so that countermeasures can be taken at any time to ensure smooth standard charging.

[0057] The charging device for a rail-mounted robot provided by this utility model can be summarized by the following four processes, as described above. Figures 1-3 :

[0058] First process: Before the rail-mounted robot 2 enters, the RFID card 4 is located between the charging component and the rail-mounted robot 2. The rail-mounted robot 2 moves towards the RFID card 4.

[0059] The second process: The track-mounted robot 2 moves into a position where the RFID card 4 and RFID antenna 201 are directly aligned. At this point, after the RFID antenna 201 reads the RFID card 4, the speed of the track-mounted robot 2 is adjusted from its initial speed (V1) towards the RFID card 4 to its current speed (V2) towards the charging component. V2 is a pre-set, fixed speed; for example, if V1 < V2, V1 increases; if V1 > V2, V1 decreases. By using the RFID card 4 and RFID antenna 201 to maintain a fixed speed for the track-mounted robot 2, regardless of its initial speed (when moving towards the RFID card 4), V2 remains constant, ensuring that the robot 2 stops at a fixed position after entering the charging component.

[0060] The third process: The track-mounted robot 2 moves into the wireless charging transmitter coil 6 and aligns with the wireless charging receiver coil 204. During this process, the track-mounted robot 2 travels at a speed of V2 to the charging assembly. The second stop 7 contacts the first limit switch 203, which outputs an I / O signal to the track-mounted robot 2, stopping it. The wireless charging transmitter coil 6 is now directly facing the wireless charging receiver coil 204. Simultaneously, the second stop 7 contacts the first limit switch 203, and the first stop 202 contacts the second limit switch 8. The second limit switch 8 outputs an I / O signal to the power-off device. After a 30-second delay, the power supply returns power to the wireless charging transmitter coil 6, enabling the track-mounted robot 2 to begin automatic charging. The charging principle of the track-mounted robot 2 is based on electromagnetic induction. When current flows through the wireless charging transmitter coil 6, it generates a magnetic field, which in turn generates an electromotive force on the wireless charging receiver coil 204, thus producing a current that charges the track-mounted robot 2.

[0061] Fourth process: The rail-mounted robot 2 moves away from the charging unit. After the rail-mounted robot 2 is charged, the first stop 202 moves away from the second limit switch 8, and the power-off device immediately cuts off the power; the second stop 7 moves away from the first limit switch 203, and the rail-mounted robot 2 continues to move.

[0062] In summary, the charging device for a rail-mounted robot provided by this utility model adopts a combination of RFID positioning and limit switches. Through precise mechanical control and positioning technology, it ensures that the rail-mounted robot 2 can accurately stop and smoothly perform wireless charging. With the cooperation of RFID antenna 201 and RFID card 4, the rail-mounted robot 2 automatically enters the charging component at a set speed and stops, ensuring a fixed speed each time it enters the charging component, thus fixing the stopping position of the rail-mounted robot 2 and ensuring more precise charging start and stop. The use of RFID positioning and limit switch control allows the rail-mounted robot 2 to reach the charging position and stop at a fixed speed.
