Referring to the fourth figure, a panel (12〇) is provided on the back of the casing (2〇), and a plurality of buttons (122) are provided to realize the setting function of the circuit device 'issuing mechanism (5〇), servo motor (60) (65) The angle sensor (8〇) (85) and the detecting member (90) are electrically connected to the circuit device (100) to generate the necessary electromechanical cooperation. The invention can be powered by an alternating current or a battery, and the panel (12〇) is provided with a switch for switching alternating current or direct current power. Referring to Figures 6 and 7, the rear end of the frame (40) has a space (48)' for mounting a battery (13〇). In this embodiment, the battery (130) is placed in a battery holder (135), and the battery holder (135) is slid into the space (48) from the rear end of the rack, as shown in the third figure. To charge the battery, pull the battery holder (135) out of the opening (28) on the back of the housing (20) (as shown in Figure 4). After the charging is completed, move the battery holder from the opening (28) into the space. (48). Therefore, the present invention is quite convenient for taking and discharging the battery without disassembling the outer casing. The ball machine (10) can be used for tennis, squash or similar ball linkage. Start the power supply of the ball machine (10) and start using it. When the service angle (104) is set, the first servo motor (60) will vertically oscillate the ball delivery mechanism (5〇) via the first link group (70), and the signal of the first angle sensor (80) The circuit device (1QQ) can be made to discriminate the rotation angle of the frame (55) of the ball feeding mechanism (50). The ball is swung to a set angle. The circuit device (100) stops the operation of the first servo motor (6〇), and the ball is positioned at the angle, so that the ball can be emitted at that angle. 200918130 The ball feeding mechanism (50) of this embodiment can be moved in an angular range of several tens of degrees. When setting the vertical swing angle (106) 'The pendulum=circle of the controllable ball-feeding mechanism (5〇) is set to swing within an angle range of 10 degrees, for example, and the upper limit angle (for example, elevation angle of 45 degrees) and the lower limit of the b range can be set. Angle (for example, elevation; degree). When the rotating shaft of the first servo motor_ rotates clockwise, that is, the frame (55) of the ball feeding mechanism is driven upward by the first link group (70) to the upper limit angle, and then the first-angle sensor bay is It is detected that the circuit device (10) rotates the clockwise direction of the motor (60) and reverses the motor (6〇) counterclockwise to drive the ball mechanism to swing downward, and the lower limit of the swing range is reached. After the angle, the '帛-angle sensor _ is detected, and the circuit device then moves (60) clockwise to make the ball-feeding mechanism (5〇) swing upward again, so that the ball-feeding mechanism can be set at an angle. Swing up and down within the range, such as the eleventh W to change the length of the tee. The vertical swing angle of the serving mechanism can be matched with the aforementioned serve angle, that is, after setting the serve angle (1〇4), the serve angle can be set as the reference angle from the reference angle by a few degrees and a few degrees downward, as the upper and lower When the horizontal swing angle is set (108), the frame (40) can be horizontally oscillated back and forth within a set angle range, for example, 8 degrees to the left and right. When the rotating shaft of the second servo motor (65) rotates in one direction, the second connecting rod group is driven (the second angle sensor (85) can detect when the rack swings to the left when the rack swings to the left. The pot swing angle is discriminated by the circuit device (100). After the frame reaches the left swing angle of the horizontal swing, the circuit device (100) stops the motor (65) from rotating and rotates the shaft in another direction. In order to drive the frame (40) to swing to the right and swing it to the right angle, the circuit device detects the second angle sensor (85) and drives the horse = (65) to drive the frame to the left again. Swing so that the ball machine (1〇) can swing horizontally back and forth, so that the ball falls on the left and right sides of the court. The user can set the ball machine to swing vertically and horizontally, so that the ball falls 11 200918130 points. In addition, the second angle sensor (85) may not be provided in practice, and when the second motor (65) rotates one week, the frame can be driven to swing horizontally back and forth via the second link set (75). The embodiment does not have the function of setting the horizontal swing angle; the frame is simply moved by the mechanism of the link set On the other hand, in the case where the second sensor (85) is provided, 'if the abnormality occurs, although the horizontal swing angle cannot be set', the ball machine still has the function of horizontal swing. b Set the serve frequency (110) When the service speed (112) is set, the rotation speed of the service wheel (54) can be adjusted to control the speed of the ball speed. The double-play mode (114) is set to activate the detection component (9) 〇) and cooperate with the horizontal swing function of the ball machine. When the frame swings to the right, the ball mechanism (5〇) is used to shoot the ball, the detecting member (9〇) and generates a tee signal, the operation list π (ΐ〇ρ detects the signal from the ball, which causes the machine (4〇) to swing to the left and mine the ball to the left of the court. After serving to the left, the gamma (9〇) will be $ Send-delete _ 峨, the transport element is the repair of the new right lion and then send the 'ball ° so so every time a ball is launched, the ball machine (10) horizontally moves to the other side, the next ball is sent The other side of the field. b » When the spin effect (116) is fixed, the two serve wheels are rotated at different speeds to make the ball spin up or down. The above functions can be used together. You, ίί^ The circuit device is additionally equipped with a safety switch (118). (When the panel (120) is operated, the silk ball machine is pressed, press the safety switch to stop the turntable. (22) 5 does not cut off the main power of the ball machine. In this way, there will be no ball, and one side will provide a safe side to prevent the person from being mistaken by the ball when the slave is in the position. The operation of the ball mechanism. 'Ϊ 测 (1f Wei' can detect the operation of the ball machine. When a certain part is abnormal, the code or code of the part will be displayed on the panel (120) and the crystal display screen ( Each part has no 12 200918130 code or code), so that you can quickly find out where the fault has occurred, without having to check it one by one. The ball machine of the present invention provides a variety of use functions as described above. According to the present invention, the first motor and the first link set can displace the ball delivery mechanism to the required serve angle ', and the motor and the link set can drive the ball delivery mechanism to continuously swing up and down without using another motor. Make the ball machine swing vertically. The present invention drives the ball machine to swing in a second motor and a second link group. The present invention senses the vertical and horizontal swing angles of the ball machine with an angle sensor to set the swing angle of the ball machine. The battery of the ball machine is easy to take, and the invention has a safe design, is safe, and provides a comprehensive inspection of the moonlight. The above is intended to illustrate the invention and not to limit it. Any equivalent implementations that are based on the following ranges should be considered as part of the present invention. The month of the invention is a new design, with specific effects, reduced to the patent requirements of the invention, and love to apply in accordance with the law.曰 [Simple description of the diagram] The i-th view is a right-view perspective view of the real side of the H.
