Detailed Description
The present invention will be described in further detail with reference to the following examples:
embodiment 1 is shown in fig. 1 and 2, and the utility model relates to a table tennis service robot, in which a ball passing device is arranged at a ball outlet 4 of the service robot. The ball passing device is arranged on the inner side of the ball outlet 4 of the pitching machine and used for protecting the ball passing device and avoiding the damage of the ball passing device caused by external force impact. The ball passing device comprises a blocking part 1 and a resetting part 2, wherein the blocking part 1 is arranged on the inner wall of a ball outlet 4 of the pitching machine and can rotate around one point. Blocking part 1 part shelters from service robot ball outlet 4, and blocking part 1 shelters from ball outlet 4 one end tip and can reduce the friction to the table tennis for the arc, extension blocking part 1 life, and the blocking part 1 other end is rectangle or other suitable shapes, and blocking part 1 adopts the preparation of high rigidity material like polycarbonate. Reset portion 2 sets up at service robot outlet 4 inboardly, and reset portion 2 is made for the spring, and spring one end is connected on stopping portion 1, and the spring other end is fixed on service robot outlet 4 inboard lateral wall. When table tennis passes through the ball outlet 4, the blocking part 1 is extruded by the table tennis and moves out of the ball outlet 4 of the ball serving machine, and the table tennis smoothly passes through the ball outlet 4 of the ball serving machine. After the table tennis passes through the ball outlet 4 of the pitching machine, the blocking part 1 is dragged by the resetting part 2 to reset to the blocking part 1 to partially shield the ball outlet 4 of the pitching machine.
In the preferred scheme, the counting device 3 is a Hall sensor arranged at one end of the blocking part 1 far away from the outlet of the pitching machine, and when the blocking part 1 partially blocks the pitching machine outlet 4, one end of the blocking part 1 far away from the outlet of the pitching machine partially blocks the counting device 3. The end part of one end of the blocking part 1, which is far away from the outlet of the pitching machine, is provided with a triggering magnetic sheet 5. When table tennis passes through ball outlet 4, blocking part 1 is shifted out service robot ball outlet 4 by the extrusion of table tennis, triggers magnetic sheet 5 and follows blocking part 1 and remove and keep away from counting assembly 3, and hall sensor triggers and transmits the count signal to receiving arrangement count, and the table tennis passes through service robot ball outlet 4 smoothly. After the table tennis passes through the service robot ball outlet 4, the blocking part 1 is dragged by the resetting part 2 to reset to the blocking part 1 to partially shield the service robot ball outlet 4, and the triggering magnetic sheet 5 is reset to the Hall sensor of the counting device 3 along with the blocking part 1.
Embodiment 2 as shown in fig. 3 is different from embodiment 1 mainly in that the counting device 3 is a pressure sensor, the reset portion 2 is a spring with one end fixed in the middle of the blocking portion 1 and the other end contacting with the pressure sensor. When table tennis passes through ball outlet 4, stopping part 1 receives the extrusion of table tennis to shift out service robot ball outlet 4, and stopping part 1 drives the spring and moves to pressure sensor direction, and the spring contracts and contacts pressure sensor, and the pressure sensor is given to the spring, and pressure sensor triggers the count. After the table tennis passes through the ball outlet 4 of the ball serving machine, the spring automatically expands to drive the blocking part 1 to partially shield the outlet of the ball serving machine from the blocking part 1.
The embodiment 2 of the utility model also has a second implementation mode as shown in figure 4, a ball outlet 4 of the spring one end fixed connection pitching machine and a blocking part 1 of the spring other end fixed connection. When table tennis passes through ball outlet 4, stopping part 1 is shifted out service robot ball outlet 4 by the extrusion of table tennis, and stopping part 1 drives the spring and moves to pressure sensor direction, and the spring extension, stopping part 1 contact pressure sensor and give pressure sensor pressure, and pressure sensor triggers the count. After the table tennis passes through the ball outlet 4 of the ball serving machine, the spring automatically contracts to drive the blocking part 1 to partially shield the outlet of the ball serving machine from the blocking part 1.
The embodiment 3 is different from the embodiment 1 mainly in that when the counting device 3 is a photoelectric sensor and the counting device 3 is arranged as a photoelectric counting sensor, the blocking part 1 blocks the counting device 3 to judge the passing of the table tennis balls and count the table tennis balls, so that an accurate counting result is obtained. Counting assembly 3 is that photoelectric sensor sets up and keeps away from service robot export one end at blocking part 1, and when blocking part 1 part sheltered from service robot output mouth 4, blocking part 1 kept away from service robot export one end and sheltered from counting assembly 3. When table tennis passes through ball outlet 4, blocking portion 1 is shifted out service robot ball outlet 4 by the extrusion of table tennis, and blocking portion 1 removes and keeps away from counting assembly 3, and photoelectric sensor triggers and transmits the count signal to receiving arrangement count, and the table tennis passes through service robot ball outlet 4 smoothly. After the table tennis passes through the ball outlet 4 of the pitching machine, the blocking part 1 is dragged by the resetting part 2 to reset to the blocking part 1 to partially shield the ball outlet 4 of the pitching machine, and the blocking part 1 resets to the photoelectric sensor of the counting device 3 to shield the photoelectric sensor.
