DETAILED DESCRIPTION

[0019] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figure 1-Figure 3 : It includes a guide rail 11, on which are provided two mounting seats 2 that can move along the guide rail 11; a rotating shaft 21 is rotatably provided on the mounting seat 2, and a clamping block 211 for clamping a workpiece is sleeved on the end of the rotating shaft 21 away from the mounting seat 2; at least two processing stations are provided on the guide rail 11, and each processing station is provided with a rotating mechanism 3 for driving the rotating shaft 21 to rotate; when the mounting seat 2 moves to the processing station, the rotating mechanism 3 at the processing station drives the rotating shaft 21 to rotate.

[0021] The present invention realizes the function of adjusting the angle of the workpiece through the guide rail 11, the mounting seat 2 and the rotating mechanism 3. The rotating mechanism 3 at multiple processing stations can control the workpiece to rotate to the corresponding angle when the workpiece moves to the designated processing station, thereby achieving the effect of automatically adjusting the angle of the workpiece according to the position of the workpiece, and solving the problem that traditional processing equipment cannot complete the installation of parts due to processing dead angles during the assembly process. The two mounting seats 2 are connected by a telescopic rod. In the process of controlling the mounting seat 2 to slide along the guide rail 11, the relative position between the two clamping blocks 211 is kept unchanged, thereby stably clamping the workpiece. A plurality of processing robots are provided on the frame 1, and the plurality of processing robots are respectively located at a plurality of processing stations. The side of the clamping block 211 away from the mounting seat 2 is provided with an anti-slip strip, and the anti-slip strip is made of rubber. In the working state, the operator clamps the workpiece through the clamping blocks 211 on the two mounting seats 2. Mounting base 2 is then controlled to move along guide rail 11. When mounting base 2 reaches a processing station, rotating shaft 21 is controlled to rotate via rotating mechanism 3. Rotating shaft 21 drives clamping block 211 and the workpiece to rotate, adjusting the workpiece angle. The processing robot then assembles the part in the set position. Adjustment by rotating mechanism 3 ensures stable exposure to the set processing station, preventing blind spots from affecting part assembly.

[0022] Reference Figure 2 、 Figure 4 and Figure 5 : The guide rail 11 includes two first ring rails 111, and the two mounting seats 2 slide with the two first ring rails 111 respectively; the mounting seat 2 is provided with a main wheel 22 rollingly connected to the first ring rail 111, and the mounting seat 2 has a built-in motor for driving the main wheel 22 to rotate.

[0023] The present invention achieves the function of controlling the periodic movement of the mounting base 2 along a specified path through the cooperation of the first ring rail 111 and the main wheel 22, thereby achieving the effect of sequentially moving the workpiece to multiple processing stations for processing, maintaining the continuity of assembly work, and improving assembly efficiency. Furthermore, the provision of the main wheel 22 can reduce wear on the mounting base 2 and the first ring rail 111 while controlling the stable movement of the mounting base 2. The first ring rail 111 is provided with an electric slip ring, and the mounting base 2 is provided with brushes electrically connected to the electric slip ring, thereby maintaining power to the internal motor of the mounting base 2 during movement. The two first ring rails 111 are coplanar and have a larger and smaller diameter. The two clamping blocks 211 are located in the annular area between the two first ring rails 111. In operation, the operator clamps the workpiece using the clamping blocks 211 on the two mounting bases 2. The motor built into the mounting base 2 then drives the main wheel 22 to rotate, thereby propelling the mounting base 2 along the first ring rail 111. The mounting seat 2 drives the clamping block 211 and the workpiece to move, and then moves the workpiece to each processing station in sequence for assembly.

[0024] Reference Figure 1 、 Figure 2 and Figure 6 : The rotating mechanism 3 includes a fixed seat 31, a bracket 32 ​​and a rotating driver 33; the fixed seat 31 is arranged on the mounting seat 2, and a transmission shaft 311 that is rotatably connected to the rotating shaft 21 is rotatably arranged on the fixed seat 31, and a docking disk 312 is sleeved on the transmission shaft 311; the bracket 32 ​​is arranged on the guide rail 11, and the rotating driver 33 is installed on the bracket 32, and the connecting frame 331 is rotatably arranged on the bracket 32, and the rotating driver 33 is used to drive the connecting frame 331 to rotate; when the connecting frame 331 cooperates with the docking disk 312, the rotating driver 33 drives the transmission shaft 311 to rotate through the connecting frame 331 and the docking disk 312.

[0025] The present invention achieves the function of driving the rotating shaft 21 to rotate by means of a fixed base 31, a bracket 32, a rotary driver 33, and a connecting frame 331. The bracket 32 ​​is provided with an extension frame, which is provided with a connecting shaft, and the connecting frame 331 is sleeved onto the connecting shaft. A pulley is sleeved onto the driving end of both the connecting shaft and the rotary driver 33, and a synchronous belt is provided on the pulleys, connecting the two pulleys. The frame 1 is provided with a controller for human-machine interaction. The rotary driver 33 is preferably a servo motor and is electrically connected to the controller. In operation, when the mounting base 2 moves to a processing station, the connecting frame 331 on the bracket 32 ​​docks with the docking plate 312. The controller then sends a signal to the rotary driver 33. Upon receiving the signal, the rotary driver 33 drives the connecting shaft to rotate via the pulley and synchronous belt. The connecting shaft drives the connecting frame 331 to rotate, which in turn drives the docking plate 312 to rotate. The docking plate 312 drives the transmission shaft 311 to rotate, which in turn drives the rotating shaft 21 and the clamping block 211 via the transmission shaft 311 to adjust the angle of the workpiece. After the adjustment is completed, the assembly work is carried out by the processing hands.

[0026] Reference Figure 3-Figure 5 : A limit block 212 is sleeved on the rotating shaft 21, and a second ring rail 112 is provided on the frame 1 for guiding the movement of the limit block 212; the axis of the second ring rail 112 is collinear with the axis of the first ring rail 111, and the second ring rail 112 is provided with a notch 1121 for the limit block 212 to rotate at each processing station.

[0027] The present invention achieves the function of stabilizing the workpiece posture through the limit block 212 and the second ring rail 112. During the process of transferring the workpiece, the second ring rail 112 and the limit block 212 cooperate to limit the rotation of the rotating shaft 21, thereby preventing the workpiece from swinging back and forth due to inertia during the movement, thereby improving the stability of the workpiece transfer. The limit block 212 is a rectangular block. When controlling the mounting base 2 to move along the guide rail 11, the main wheel 22 is driven to rotate by the motor built into the mounting base 2, pushing the mounting base 2 to move. During the movement, the limit block 212 is limited in rotation by the sliding cooperation with the second ring rail 112. The limit block 212 is connected to the rotating shaft 21, which in turn limits the rotation of the rotating shaft 21, thereby preventing the workpiece and the clamping block 211 from rotating. When the mounting base 2 moves to the processing station, the limit block 212 moves to the notch 1121 of the second ring rail 112. At this point, the rotating shaft 21 is driven to rotate by the rotating mechanism 3, which in turn drives the limit block 212 to rotate. The limit block 212 is located in the notch 1121 of the second ring rail 112, and the second ring rail 112 does not affect the rotation of the limit block 212. When the workpiece is rotated to the specified angle, the rotating mechanism 3 stops driving, and assembly processing continues. After processing is completed, the rotating shaft 21 is again driven to rotate by the rotating mechanism 3 until the rotating shaft 21 rotates 360°, completing the reset of the workpiece. Then, when the mounting base 2 is controlled to move along the first ring rail 111, the limit block 212 will once again slide with the second ring rail 112 to limit the rotation of the rotating shaft 21.

[0028] Reference Figure 6 and Figure 7 : A support 1122 is provided at the notch 1121 of the second ring rail 112, and a sensor 1123 is provided on the support 1122; an annular seat 213 is sleeved on the rotating shaft 21, and a positioning ring 214 is installed on the annular seat 213, and a positioning block 2141 for cooperating with the sensor 1123 is provided on the positioning ring 214.

[0029] The present invention utilizes the support 1122, sensor 1123, annular seat 213, and positioning ring 214 to precisely control the angle of the rotating shaft 21 when the rotating shaft 21 is driven to rotate. The sensor 1123 is a Hall effect sensor 1123, and the positioning block 2141 includes a magnetic head that cooperates with the Hall effect sensor 1123. The sensor 1123 can also be a photoelectric sensor 1123, and a reflector that cooperates with the photoelectric sensor 1123 is provided on the positioning block 2141. The sensors 1123 at different processing stations have different heights, thereby cooperating with the positioning blocks 2141 on positioning rings 214 of different diameters. Multiple positioning rings 214 are provided, each with different diameters. The positioning blocks 2141 on each positioning ring 214 are located at different positions. The sensors 1123 located at different processing stations each cooperate with the multiple positioning blocks 2141, thereby setting different positioning angles at each processing station. During operation, when the mounting seat 2 moves to the processing position, the rotating mechanism 3 drives the rotating shaft 211 to rotate. The rotating shaft 21 drives the annular seat 213 and the positioning ring 214 to rotate, and the positioning ring 214 drives the positioning block 2141 to rotate synchronously. When the positioning block 2141 is aligned with the sensor 1123, the sensor 1123 feeds back a signal to the controller. After receiving the signal, the controller stops the rotating mechanism 3 to improve the processing accuracy.

[0030] Reference Figure 6 and Figure 7 The positioning ring 214 is detachably arranged on the annular seat 213 . The annular seat 213 is provided with a convex tooth 2131 . The positioning ring 214 is provided with a first groove that cooperates with the convex tooth 2131 .

[0031] The present invention realizes the function of quickly adjusting the installation angle of the positioning ring 214 through the protruding teeth 2131 of the annular seat 213 and the first groove. In order to improve the installation portability and installation stability of the positioning ring 214, magnetic installation or bolt connection can be used to quickly install the positioning ring 214. In order to quickly locate the processing angle of the workpiece, the sensor 1123 cooperates with the positioning block 2141 on the positioning ring 214 at the processing station to accurately position it. When adjusting the processing position of the processing station, the operator removes the positioning ring 214, adjusts the positioning block 2141 on the positioning ring 214 to the specified position, and then reinstalls the positioning ring 214, thereby quickly adjusting the positioning position of the positioning ring 214.

[0032] Reference Figure 6 and Figure 7 : A first rotating gear 215 is provided on the mounting base 2 and is transmission-connected to the rotating shaft 21 , and a second rotating gear 3111 is sleeved on the transmission shaft 311 and is meshedly connected to the first rotating gear 215 .

[0033] The present invention realizes the function of driving the rotating shaft 21 to rotate when the transmission shaft 311 rotates through the first rotating gear 215 and the second rotating gear 3111. The first rotating gear 215 is sleeved on the annular seat 213. A movable frame 24 is slidingly provided on the mounting seat 2, and the movable frame 24 is connected to the mounting seat 2 through a compression spring. The rotating shaft 21 is rotatably provided on the movable frame 24, and a telescopic shaft is rotatably provided on the movable frame 24. The transmission shaft 311 is sleeved on the telescopic shaft so as to be able to move axially, while retaining the buffering effect of the movable frame 24, maintaining the transmission connection between the transmission shaft 311 and the rotating shaft 21. When the mounting seat 2 moves to the processing station, the transmission shaft 311 is driven to rotate by the rotary driver 33, and the transmission shaft 311 drives the second rotating gear 3111 to rotate, and the second rotating gear 3111 drives the first rotating gear 215 meshed with it to rotate.

[0034] Reference Figure 4 、 Figure 5 、 Figure 8 and Figure 9 : A movable seat 23 is provided on the mounting seat 2, and a second elastic member 231 connected to the mounting seat 2 is provided on the movable seat 23; an annular slide rail is provided on the first ring rail 111, and a secondary wheel 232 is rotatably provided on the movable seat 23 and is rollingly connected to the first ring rail 111, and the secondary wheel 232 is located in the annular slide rail; a loading station and an unloading station are provided on the first ring rail 111, and a second groove 1111 is provided at the loading station and the unloading station of the first ring rail 111; when the mounting seat 2 moves to the second groove 1111, the distance between the two mounting seats 2 increases and the workpiece is released.

[0035] The present invention realizes the function of automatically adjusting the distance between the two mounting seats 2 through the second groove 1111 and the movable seat 23, thereby achieving the function of automatically loosening the workpiece during blanking. The elastic force provided by the second elastic member 231 enables the main wheel 22 on the mounting seat 2 to stably fit the first ring rail 111. When the mounting seat 2 moves to the second groove 1111, the mounting seat 2 moves into the second groove 1111, thereby increasing the distance between the two mounting seats 2. The distance between the clamping blocks 211 on the two mounting seats 2 also increases, thereby loosening the workpiece. When clamping the workpiece, the workpiece is placed between the two clamping blocks 211. During the process of the mounting seat 2 moving out of the second groove 1111, the distance between the two clamping blocks 211 gradually decreases, thereby clamping the workpiece. During the movement of the mounting seat 2, the two second ring rails 112 guide the mounting seat 2, so that the clamping blocks 211 can stably clamp the workpiece.

[0036] Reference Figure 1 、 Figure 2 and Figure 10: A clamping block 332 is provided on the connecting frame 331, and a third elastic member 333 connected to the connecting frame 331 is provided on the clamping block 332; a docking groove 3121 that cooperates with the clamping block 332 is opened on the docking plate 312.

[0037] The present invention realizes the function of quickly connecting the docking plate 312 and the connecting frame 331 through the clamping block 332, the third elastic member 333 and the docking groove 3121. A bevel is provided on one side of the clamping block 332. When the mounting seat 2 approaches the processing station, the docking plate 312 squeezes the bevel of the clamping block 332, and the clamping block 332 shrinks. Even if the limit block 212 is no longer restricted by rotation at this time, the docking plate 312 can rotate, and the docking plate 312 can also press the clamping block 332 into the connecting frame 331 during the rolling process. When the mounting seat 2 moves to the processing station, the docking plate 312 moves to the connecting frame 331, and the axis of the docking plate 312 is collinear with the axis of the connecting shaft. Then the rotary driver 33 drives the connecting shaft and the connecting frame 331 to rotate through the pulley and the synchronous belt. The connecting frame 331 drives the clamping block 332 to rotate. When the clamping block 332 is aligned with the docking groove 3121, the clamping block 332 is plugged into the docking groove 3121 under the elastic force of the third elastic member 333, and then the clamping block 332 pushes the groove wall of the docking groove 3121 to push the docking plate 312 to rotate.
