[0009] Preferably, the clamping mechanism includes two symmetrically arranged second L-shaped plates fixedly connected to the top of the annular tube, and a connecting rod is fixedly connected to the bottom of each second L-shaped plate. A connecting plate is fixedly connected to the lower end of the connecting rod, and a moving block is connected to the side wall of the connecting plate through a telescopic mechanism.

[0010] Preferably, the telescopic mechanism includes two symmetrically arranged second sleeves fixedly connected to the side wall of the connecting plate, and a second sleeve rod is inserted into each second sleeve. The other end of the second sleeve rod is fixed to the side wall of the moving block, and a third spring is sleeved on the side wall of each second sleeve.

[0012] Preferably, the pushing mechanism includes a pushing rod fixedly connected to the end of the T-shaped guide rod, and an L-shaped frame is fixedly connected to the side wall of the pushing plate. The side wall of the L-shaped frame is connected to a plurality of arrayed triangular blocks through a one-way rotation mechanism.
[0013] Preferably, the unidirectional rotation mechanism includes a first connecting block fixedly connected to the side wall of each triangular block, and a second connecting block is rotatably connected to the side wall of the first connecting block via a rotating shaft.

[0015] A fully automatic dial pointer pressing method, using the aforementioned fully automatic dial pointer pressing equipment, includes the following steps:
[0016] S1: When it is necessary to press the dial pointers, the positioning mold is transported by the conveyor belt. When it is transported into the box, the dial is adsorbed by the pneumatic suction cup of the first robot and placed on the positioning mold for positioning. Then, the mounting plate is moved by the second robot to move above the first material tray. Then, the mounting plate is moved downward by the second robot so that the rectangular tube fits with the pointer. At the same time, the solenoid valve is opened and the external air extraction device is used to perform air extraction. Air can be extracted through the air extraction hole to adsorb the pointer. Then, the second robot moves to the top of the dial and presses the three pointers in sequence.
[0017] S2: During press-fitting, the second robotic arm drives the mounting plate and pointer downwards. When the pointer is pressed onto the pointer shaft, the second spring can be gradually compressed, and the distance between the mounting plate and the rectangular tube gradually decreases. At the same time, the distance sensor detects the change in the distance of the rectangular tube, which determines the compression amount of the second spring. This, in turn, controls the squeezing force of the rectangular tube on the pointer during press-fitting, ensuring the quality and efficiency of the press-fitting. Furthermore, when the annular tube moves downwards, the second L-shaped plate and connecting rod can drive the connecting plate downwards, and the telescopic mechanism can drive the moving block and V-shaped block downwards, so that the V-shaped block can be aligned with the pointer shaft and located below the pointer body.
[0018] S3: When the mounting plate moves towards the rectangular tube, it can drive the push plate to move downward. When the inclined surface abuts against the top of the moving block, it can push the two moving blocks to move closer to each other. At the same time, the third spring is stretched, causing the V-block to abut against the side wall of the pointer shaft, thus clamping and fixing the pointer shaft. Furthermore, when the push plate moves downward, it can drive multiple triangular blocks to move downward through the L-shaped frame and the one-way rotation mechanism. When the triangular block abuts against the end of the push rod, the triangular block can rotate upward along the rotation axis. At this time, it will not push the T-shaped guide rod to move.
[0019] S4: After pressing is completed, the second robotic arm moves the mounting plate upward. At this time, the second spring gradually returns to its original position. Then, the push plate and L-shaped frame can drive multiple triangular blocks to move upward. When the triangular blocks abut against the end of the push rod, the stop block abuts against the side wall of the limit block, preventing the triangular blocks from rotating downward. At this time, the T-shaped guide rod can be pushed to move away from the triangular blocks. At the same time, the first spring is compressed. When the end of the push rod passes the triangular blocks, the T-shaped guide rod can move and return to its original position under the action of the first spring. This process is repeated to make the T-shaped guide rod move back and forth. At the same time, it drives the rubber rod to move back and forth and abut against the side wall of the pointer body. By observing whether the pointer body rotates through the visual sensor, the tightness after pressing can be determined, ensuring the quality of pressing.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] (1) This fully automatic dial pointer pressing equipment, by setting a pressure control mechanism, etc., when it is necessary to press the dial pointer, the positioning mold is conveyed by the conveyor belt. When it is conveyed into the box, the dial is adsorbed by the pneumatic suction cup of the first robot and placed on the positioning mold for positioning. Then, the mounting plate is moved by the second robot to move above the first material tray. Then, the mounting plate is moved downward by the second robot so that the rectangular tube fits with the pointer. At the same time, the solenoid valve is opened and the external air extraction device is used to perform air extraction, so that air can be extracted through the air extraction hole to adsorb the pointer. Then, the second robot moves to the dial. Above, three pointers are pressed in sequence. During pressing, the second robotic arm moves the mounting plate and pointers downward. When the pointers are pressed onto the pointer shaft, the second spring is gradually compressed, and the distance between the mounting plate and the rectangular tube gradually decreases. At the same time, the distance sensor detects the change in the distance to the rectangular tube, which determines the compression of the second spring and the squeezing force of the rectangular tube on the pointers, ensuring the quality and efficiency of pressing. Furthermore, when the annular tube moves downward, the second L-shaped plate and connecting rod can drive the connecting plate downward, and the telescopic mechanism can drive the moving block and V-shaped block downward, so that the V-shaped block can be aligned with the pointer shaft and located below the pointer body.
[0022] (2) This fully automatic dial pointer pressing equipment, by setting up a detection mechanism, etc., during pressing, when the mounting plate moves towards the rectangular tube, it can drive the push plate to move downward. When the inclined surface abuts against the top of the moving block, it can push the two moving blocks to move closer to each other. At the same time, the third spring is stretched, and the V-block abuts against the side wall of the pointer shaft, thereby clamping and fixing the pointer shaft. Furthermore, when the push plate moves downward, it can drive multiple triangular blocks to move downward through the L-shaped frame and the one-way rotation mechanism. When the triangular block abuts against the end of the push rod, the triangular block can rotate upward along the rotation axis. At this time, it will not push the T-shaped guide rod to move. After pressing is completed, the second robot arm drives the mounting plate towards the rectangular tube. As the pointer moves upward, the second spring gradually returns to its original position. At this point, the push plate and L-shaped frame can drive multiple triangular blocks to move upward. When the triangular blocks abut against the end of the push rod, the stop block abuts against the side wall of the limit block, preventing the triangular blocks from rotating downward. At this point, the T-shaped guide rod can be pushed to move away from the triangular blocks. Simultaneously, the first spring is compressed. When the end of the push rod passes the triangular blocks, the T-shaped guide rod can move and return to its original position under the action of the first spring. This process is repeated, allowing the T-shaped guide rod to move back and forth. At the same time, it drives the rubber rod to move back and forth and abut against the side wall of the pointer body. By observing whether the pointer body rotates through a visual sensor, the tightness after pressing can be determined, ensuring the quality of pressing. Attached Figure Description

A clamping mechanism for clamping and fixing the pointer shaft is provided on the side wall of the annular tube 1103. After the press-fitting is completed, the pointer shaft is clamped and fixed by the clamping mechanism. At the same time, the T-shaped guide rod 402 is moved by the pushing mechanism, which drives the rubber rod 404 to move back and forth and abut against the side wall of the pointer body. The tightness after press-fitting can be determined by observing whether the pointer body rotates through the vision sensor 405, thus ensuring the quality of press-fitting.
[0036] Please see Figure 5 The pressure control mechanism includes two symmetrically arranged first sleeves 202 fixedly connected to the bottom of the fixed plate 1101, and a first sleeve rod 201 is inserted into each first sleeve 202. The lower end of the first sleeve rod 201 is fixed to the top of the rectangular tube 1102. A second spring 203 is sleeved on the side wall of each first sleeve 202. A distance sensor 204 is fixedly connected to the bottom of the fixed plate 1101. During the pressing process, the second manipulator 109 drives the mounting plate 10 and the pointer to move downward. When the pointer is pressed onto the pointer shaft, the second spring 203 can be gradually compressed, and the distance between the mounting plate 10 and the rectangular tube 1102 gradually decreases. At the same time, the distance sensor 204 detects the change in the distance of the rectangular tube 1102, thereby determining the compression amount of the second spring 203 and the squeezing force of the rectangular tube 1102 on the pointer during pressing, ensuring the quality and efficiency of the pressing process.
[0037] Please see Figure 7The clamping mechanism includes two symmetrically arranged second L-shaped plates 501 fixedly connected to the top of the annular tube 1103, and a connecting rod 505 fixedly connected to the bottom of each second L-shaped plate 501.

A V-shaped block 504 is fixedly connected to the side wall of the moving block 503, and the movement of the moving block 503 is driven by a pushing component. The pushing component pushes the two moving blocks 503 to move closer to each other, and drives the two V-shaped blocks 504 to move closer to each other, so that the V-shaped block 504 abuts against the side wall of the pointer shaft, thereby clamping and fixing the pointer shaft.
[0038] Please see Figure 7 The telescopic mechanism includes two symmetrically arranged second sleeves 601 fixedly connected to the side wall of the connecting plate 502, and a second sleeve rod 602 is inserted into each second sleeve 601. The other end of the second sleeve rod 602 is fixed to the side wall of the moving block 503, and a third spring 603 is sleeved on the side wall of each second sleeve 601, which guides and resets the movement of the moving block 503.

The bottom of the pushing plate 701 is provided with an inclined surface 702, and the moving block 503 can slide on the inclined surface 702. When the mounting plate 10 moves towards the rectangular tube 1102, it can drive the pushing plate 701 to move downward. When the inclined surface 702 abuts against the top of the moving block 503, it can push the two moving blocks 503 to move closer to each other.
[0040] Please see Figure 7 and Figure 8The pushing mechanism includes a pushing rod 801 fixedly connected to the end of the T-shaped guide rod 402, and an L-shaped frame 802 fixedly connected to the side wall of the pushing plate 701. The side wall of the L-shaped frame 802 is connected to multiple arrayed triangular blocks 803 via a one-way rotation mechanism. During press-fitting, when the mounting plate 10 moves towards the rectangular tube 1102, it can drive the pushing plate 701 downwards. When the inclined surface 702 abuts against the top of the moving block 503, it can push the two moving blocks 503 closer together. Simultaneously, the third spring 603 is stretched, causing the V-shaped block 504 to abut against the side wall of the pointer shaft, achieving clamping and fixing of the pointer shaft. Furthermore, when the pushing plate 701 moves downwards, it can... The L-shaped frame 802 and the one-way rotation mechanism drive multiple triangular blocks 803 to move downwards. When the triangular block 803 abuts against the end of the push rod 801, the triangular block 803 can rotate upwards along the rotating shaft 902. At this time, it will not push the T-shaped guide rod 402 to move. After the pressing is completed, the second robot arm 109 drives the mounting plate 10 to move upwards. At this time, the second spring 203 gradually resets. At this time, the push plate 701 and the L-shaped frame 802 can drive multiple triangular blocks 803 to move upwards. When the triangular block 803 abuts against the end of the push rod 801, the triangular block 803 cannot rotate downwards. At this time, it can push the T-shaped guide rod 402 to move away from the triangular block 803.
[0041] Please see Figure 8 The one-way rotation mechanism includes a first connecting block 903 fixedly connected to the side wall of each triangular block 803, and a second connecting block 901 rotatably connected to the side wall of the first connecting block 903 via a rotating shaft 902.

When the push plate 701 moves downward, it can drive multiple triangular blocks 803 downward through the L-shaped frame 802 and the one-way rotation mechanism. When the triangular block 803 abuts against the end of the push rod 801, the triangular block... 803 can rotate upward along the pivot 902. At this time, it will not push the T-shaped guide rod 402 to move. After the pressing is completed, the second robot arm 109 drives the mounting plate 10 to move upward. At this time, the second spring 203 gradually resets. At this time, the push plate 701 and the L-shaped frame 802 can drive multiple triangular blocks 803 to move upward. When the triangular block 803 abuts against the end of the push rod 801, the stop block 904 can abut against the side wall of the limit block 905, so that the triangular block 803 cannot rotate downward. At this time, the T-shaped guide rod 402 can be pushed to move away from the triangular block 803.
[0042] Please see Figure 5The air extraction mechanism includes multiple fixed blocks 301 fixedly connected to the side wall of the mounting plate 10, and a solenoid valve 302 is fixedly connected to the top of each fixed block 301. The solenoid valve 302 is connected to an external air extraction device through an air pipe. The rectangular tube 1102 is connected to the solenoid valve 302 through a flexible tube 303. When the solenoid valve 302 is opened, the external air extraction device performs an air extraction operation, thereby extracting air through the air extraction hole 1104, thereby attracting the pointer.
[0043] A fully automatic dial pointer pressing method, using the aforementioned fully automatic dial pointer pressing equipment, includes the following steps:
[0044] S1: When it is necessary to press the dial pointer, the positioning mold 104 is conveyed by the conveyor belt 103. When it is conveyed into the box 102, the dial is adsorbed by the pneumatic suction cup 108 of the first robot arm 107 and placed on the positioning mold 104 for positioning. Then, the mounting plate 10 is moved by the second robot arm 109 to move above the first material tray 105. Then, the mounting plate 10 is moved downward by the second robot arm 109 so that the rectangular tube 1102 is in contact with the pointer. At the same time, the solenoid valve 302 is opened and the external air extraction device is used to perform air extraction, so that air can be extracted through the air extraction hole 1104 to adsorb the pointer. Then, the second robot arm 109 moves to the top of the dial and presses the three pointers in sequence.
[0045] S2: During the pressing process, the second robotic arm 109 drives the mounting plate 10 and the pointer to move downwards. When the pointer is pressed onto the pointer shaft, the second spring 203 can be gradually compressed, and the distance between the mounting plate 10 and the rectangular tube 1102 gradually decreases. At the same time, the distance sensor 204 detects the change in the distance of the rectangular tube 1102, thereby determining the compression amount of the second spring 203. This ensures the pressing force of the rectangular tube 1102 on the pointer, guaranteeing the quality and efficiency of the pressing process. Furthermore, when the annular tube 1103 moves downwards, the second L-shaped plate 501 and the connecting rod 505 can drive the connecting plate 502 to move downwards, and the telescopic mechanism can drive the moving block 503 and the V-shaped block 504 to move downwards, so that the V-shaped block 504 can be aligned with the pointer shaft and located below the pointer body.
[0046] S3: When the mounting plate 10 moves toward the rectangular tube 1102, it can drive the push plate 701 to move downward. When the inclined surface 702 abuts against the top of the moving block 503, it can push the two moving blocks 503 to move closer to each other. At the same time, the third spring 603 is stretched, and the V-shaped block 504 abuts against the side wall of the pointer shaft, thereby clamping and fixing the pointer shaft. When the push plate 701 moves downward, it can drive multiple triangular blocks 803 to move downward through the L-shaped frame 802 and the one-way rotation mechanism. When the triangular block 803 abuts against the end of the push rod 801, the triangular block 803 can rotate upward along the rotating shaft 902. At this time, it will not push the T-shaped guide rod 402 to move.
[0047] S4: After pressing is completed, the second robotic arm 109 drives the mounting plate 10 to move upward. At this time, the second spring 203 gradually resets. Then, the push plate 701 and L-shaped frame 802 can drive multiple triangular blocks 803 to move upward. When the triangular block 803 abuts against the end of the push rod 801, the stop block 904 can abut against the side wall of the limit block 905, so that the triangular block 803 cannot rotate downward. At this time, the T-shaped guide rod 402 can be pushed to move away from the triangular block 803. At the same time, the first spring 403 is compressed. When the end of the push rod 801 passes the triangular block 803, the T-shaped guide rod 402 can move and reset under the action of the first spring 403. This process is repeated so that the T-shaped guide rod 402 can move back and forth. At the same time, it drives the rubber rod 404 to move back and forth and abut against the side wall of the pointer body. By observing whether the pointer body rotates through the vision sensor 405, the tightness after pressing can be determined, ensuring the quality of pressing.

9. A fully automatic dial hand press fitting method using the fully automatic dial hand press fitting apparatus according to any one of claims 1 to 8, characterized by: The method comprises the following steps: S1: when the dial pointer needs to be pressed, the positioning mold (104) is conveyed through the conveying belt (103), when conveyed into the box (102), the dial is adsorbed and placed on the positioning mold (104) through the pneumatic suction cup (108) of the first mechanical hand (107) for positioning, then the mounting plate (10) is moved by the second mechanical hand (109), and the rectangular pipe (1102) is moved to the upper side of the first tray (105), then the mounting plate (10) is moved downward by the second mechanical hand (109), so that the rectangular pipe (1102) is combined with the pointer, at the same time, the electromagnetic valve (302) is opened, and the air extraction equipment is used for air extraction operation, so that the air extraction hole (1104) is used for air extraction, so that the pointer is adsorbed, then the second mechanical hand (109) is moved to the upper side of the dial, and three pointers are pressed in sequence. S2: When the installation plate (10) is moved towards the rectangular tube (1102), the second spring (203) can be gradually compressed, and the distance between the installation plate (10) and the rectangular tube (1102) gradually decreases. At the same time, the distance sensor (204) detects the change in the distance of the rectangular tube (1102), which determines the compression amount of the second spring (203), and further determines the extrusion force of the rectangular tube (1102) on the pointer during the pressing process, ensuring the quality and efficiency of the pressing process. When the annular tube (1103) moves downward, the second L-shaped plate (501) and the connecting rod (505) drive the connecting plate (502) to move downward, and the telescopic mechanism drives the moving block (503) and the V-shaped block (504) to move downward, so that the V-shaped block (504) can be aligned with the pointer shaft and located below the pointer body; S3: When the installation plate (10) moves towards the rectangular tube (1102), the push plate (701) moves downward, and when the inclined surface (702) abuts against the top of the moving block (503), the two moving blocks (503) are pushed to move closer to each other, and at the same time, the third spring (603) is stretched, and the V-shaped block (504) abuts against the side wall of the pointer shaft, realizing clamping and fixing of the pointer shaft. When the push plate (701) moves downward, the L-shaped frame (802) and the one-way rotation mechanism drive the plurality of triangular blocks (803) to move downward, and when the triangular blocks (803) abut against the end of the push rod (801), the triangular blocks (803) can rotate upward along the rotation shaft (902). At this time, the T-shaped guide rod (402) will not be pushed to move; S4: After the pressing is completed, the second mechanical hand (109) drives the installation plate (10) to move upward, and at this time, the second spring (203) is gradually reset. At this time, the push plate (701) and the L-shaped frame (802) drive the plurality of triangular blocks (803) to move upward, and when the triangular blocks (803) abut against the end of the push rod (801), the stop block (904) abuts against the side wall of the limiting block (905), so that the triangular blocks (803) cannot rotate downward. At this time, the T-shaped guide rod (402) can be pushed to move away from the triangular blocks (803), and at the same time, the first spring (403) is compressed. When the end of the push rod (801) passes the triangular blocks (803), the T-shaped guide rod (402) can move back under the action of the first spring (403). In this way, the T-shaped guide rod (402) can move back and forth, and at the same time, the rubber rod (404) can move back and forth and abut against the side wall of the pointer body. The visual sensor (405) observes whether the pointer body rotates, which can determine the fastening after the pressing.
