There is a need to further reduce the costs of the robotic teach pendant 10.
[0028] Popular use of portable electric devices, such as mobile phone, a laptop, a tablet, and various other smart electric devices, makes it possible to take over some functions of the robotic teach pendant 10. For example, some components, such as the keyboard and the display may be removed from the robotic teach pendant 10 so as to reduce the costs of the robotic teach pendant 10. According to the present disclosure, there is provided a novel robotic teach pendant which can be used with a portable electric device.
[0029] Fig. 2 is a schematic view of a robotic teach pendant 10 according to one example embodiment of the present disclosure. As shown in Fig. 2, the robotic teach pendant 10 may include a housing 12, an enabling button 14 and an emergency stop button 17. The enabling button 14 and emergency stop button 17 may be provided on an outer surface of the housing 12 which can be easily accessed by the user’s hand. The robotic teach pendant 10 also includes a magnetic attaching device 16. The magnetic attaching device 16 is provided on the housing 12. The magnetic attaching device 16 is configured to magnetically attract a portable electronic device 20 comprising a display such that the display of the portable electronic device 20 can be used as an interface for teaching and / or programming the robot.
[0030] The magnetic attaching device may be provided at a proper position on the housing 12 where a secure connection can be established. The size of the magnetic attaching device should provide sufficient magnetitic attractive forces for holding the portable electronic device 20. In some embodiments, the magnetic attaching device 16 may be provided on an outer surface of the housing 12. In some embodiments, the magnetic attaching device 16 may be embedded in the outer surface of the housing 12.
[0031] During use, the portable electronic device 20 should be securely and detachably fixed to the robotic teach pendant 10. The undesired detachment of the portable electronic device 20 from the robotic teach pendant 10 should be avoided. In some embodiments, as shown in Fig. 1, the magnetic attaching device 16 comprises a plurality of magnets 162 (also called magnet array) . Each magnet 162 of the magnet array has a magnetic pole direction perpendicular to a flat surface where the magnetic attaching device 16 is located. When a plurality of magnets is comprised by the magnetic attaching device 16, a larger magnetic attractive force is provided compared with a single one magnet.
[0032] In some embodiments, the magnet array may be shaped in a ring shape. As shown in Fig. 2, the plurality of magnets 162 are circumferentially arranged one by one. A circumferential gap is defined between two adjacent magnets. The ring shape of the magnet array may bring about additional function in addition to providing sufficient magnetic attractive force, which is described later.
[0033] There are many ways for arranging the magnetic attaching device 16 on / in the housing 12 of the robotic teach pendant 10. Fig. 3 is a perspective view a magnetic attaching device 16 comprised by the robotic teach pendant according to one example embodiment of the present disclosure. As shown in Fig. 3, the magnetic attaching device 16 may comprise a bracket 164 configured to support the plurality of magnets 162. The bracket 164 may fixed to the housing 12. In some embodiments (not shown) , the housing 12 may includes a plurality of grooves for receiving the plurality of magnets of the magnetic attaching device 16. The plurality of magnets of the magnetic attaching device 16 may be mounted in the plurality of grooves of the housing. In some embodiments, the magnetic attaching device 16 may be exposed to the user. Alternatively, the magnetic attaching device 16 may be hidden in the housing.
[0034] In some embodiments, the robotic teach pendant 10 may further comprise a second magnetic attaching device 26 (referring to Fig. 5) for cooperating with the first magnetic attaching device 16. The second magnetic attaching device 26 may be fixed to the portable electronic device 20 such that the portable electronic device 20 is magnetically fixed to the robotic teach pendant 10 via interaction between the first and the second magnetic attaching devices. In some embodiments, the second magnetic attaching device 26 may be made of a magnetic conductive material and / or one or more magnets. In some embodiments, as shown in Fig. 5, the second magnetic attaching device 26 may be formed as an integral iron ring. It is to be understood that the second magnetic attaching device may be of any other proper shapes.
[0035] In some embodiments, the second magnetic attaching device 26 may be used as an accessory to the robotic teach pendant 10. When there is a need to attach the electronic device 20 to the robotic teach pendant 10, the second magnetic attaching device 26 may be used to be fixed to the electronic device 20.
[0036] There are various means for attaching the second magnetic attaching device 26 to the electronic device 20. In some embodiments, the second magnetic attaching device 26 is detachably fixed to the electronic device 20 via adhesive. In some embodiments, the second magnetic attaching device 26 may comprise an adhesive tape. The second magnetic attaching device 26 may be fixed to the portable electronic device 20 via the adhesive tape.
[0037] In some embodiments, the robotic teach pendant 10 may also provide charging function for the portable electronic device 20. As shown in Fig. 2, the robotic teach pendant 10 may comprise a charging coil 18 configured to charge the portable electronic device 20 when the portable electronic device 20 is fixed to the housing 12 of the robotic teach pendant 10. The charging coil 18 may be placed in a center of the magnet array ring. In some embodiments, the robotic teach pendant 10 may comprise an aligning apparatus for aligning the charging coil 18 with a respective charging coil 28 (referring to Fig. 5) in the portable electronic device 20. The charging coil 18 should be aligned with the respective charging coil 28 during a charging process. When the charging coil 18 and the respective charging coil 28are misaligned, energy is often lost as heat, which is also not good for battery health. In some embodiments, the magnetic attaching device 16 may also be used as the aligning apparatus. In particular, when the magnetic attaching device 16 is formed as magnetic array ring formed by a plurality of magnets 162, the magnetic attaching device 16 is attached to the portable electronic device 20 at a predetermined position in a self-aligned way.
[0038] Fig. 4 is perspective view after a portable electric device 20 is attached to the robotic teach pendant 10 according to one example embodiment of the present disclosure; and Fig. 5 is perspective view before the portable electric device is attached to the robotic teach pendant according to one example embodiment of the present disclosure. The state shown in Fig. 4 may be corresponding to a state that the user is programming the robot by using the screen of the portable electric device 20. Fig. 5 is perspective view before the portable electric device 20 is attached to the robotic teach pendant 10 according to one example embodiment of the present disclosure. Fig. 5 also schematically shows the magnetic attaching device 16 and the charging coil 18 on the robotic teach pendant 10 and the respective magnetic attaching device 26 and the respective charging coil 28 on the robotic teach pendant 10. The shown arrangement is merely illustrative. It is to be understood that the magnetic attaching device 16 and the charging coil 18 on the robotic teach pendant 10 and / or the respective magnetic attaching device 26 and the respective charging coil 28 on the robotic teach pendant 10 may be invisible to the user.
[0039] In some embodiments, as shown in Fig. 5, the robotic teach pendant 10 may further comprise a wireless connection 11; at least one processor 13; and at least one memory 15 including computer program code. The computer program code, when executed by the processor 13, is configured to: detect whether the robotic teach pendant 10 is charging the portable electronic device 20; and in response to determining that the robotic teach pendant 10 is not charging the portable electronic device 20, disconnecting the wireless connection 11 between the portable electronic device 20 and the robotic teach pendant 10. This may further improve the safety.
[0040] After the portable electronic device 20 and the robotic teach pendant 10 establishes a wireless connection, the user can program and / or control the robot 30 by the portable electronic device 20. Controlling the robot 30 merely by the portable electronic device 20 may be dangerous. Thus, the portable electronic device 20 should not be physically separated from the robotic teach pendant 10. Taking the following scenario as an example, the portable electronic device 20 such as phone or tablet is held by a first person while the teach pendant unit is held by the second person control the phone or the tablet. The user would be more likely to operate the portable electronic device 20 than the robotic teach pendant because the portable electronic device 20 has better user interface such as screen and joystick. However, if an emergency circumstance occurs, since the portable electronic device 20 is not equipped with stop and enabling buttons, the first person cannot stop the robot in time, which would be quite dangerous and is not allowed by safety regulations. Therefore, it is required to make the communication between the teach pendant 10 unit and the portable electronic device 20 to be disconnected quickly as soon as they are physically disconnected. According to the present disclosure, by detecting whether the robotic teach pendant 10 is charging the portable electronic device 20, it provides an easy way for disconnecting the wireless connection 11 between the portable electronic device 20 and the robotic teach pendant 10. This is beneficial in terms of safety.
