At present, a robotic arm is combined with a clamp with a vacuum suction cup to pick up the stamped air-conditioning outdoor unit panel on the conveyor line and hang it on the hook of the chain. However, when there are slight bumps or debris on the air-conditioning outdoor unit panel, air leakage is likely to occur, resulting in unstable holding of the air-conditioning outdoor unit panel, causing the air-conditioning outdoor unit panel and the clamp to shift relative to each other, which will cause the air-conditioning outdoor unit panel to be unable to be hung on the hook, or even the air-conditioning outdoor unit panel may fall off during the transfer process, which is not conducive to the stable progress of automated production. Therefore, it is necessary to improve the above-mentioned clamp. Summary of the invention

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] The utility model of the air conditioner external unit panel hanging pick and place device, such as Figure 1 , Figure 2 and Figure 6 As shown, it includes a connecting plate 1 for installing and connecting the end of the robot arm 901, two carrying rods 2 are installed on one side of the connecting plate 1, and magnetic suction heads 3 are respectively provided at both ends of the carrying rods 2, so the number of magnetic suction heads 3 is four, as shown in FIG. Figure 1 , Figure 2 and Figure 4 As shown, the magnetic head 3 includes a lifting plate 31, a telescopic rod 32, a cylinder mounting plate 33, a magnetic cylinder 34 and a first compression spring 35 (it should be noted that only Figure 2 and Figure 4The first compression spring 35 is schematically drawn, a suction cup portion 341 for contact-holding the outer surface 991 of the panel 99 is formed at one end of the magnetic cylinder 34, and the other end of the magnetic cylinder 34 is connected to the cylinder mounting plate 33, and one end of the telescopic rod 32 is connected to the cylinder mounting plate 33, and the telescopic rod 32 is slidably connected to one end of the lifting plate 31, and a T-slot 21 is formed on the carrying rod 2, and the other end of the lifting plate 31 is relatively fixedly connected to the T-slot 21 through corresponding fasteners, and the first compression spring 35 is sleeved on the outside of the telescopic rod 32, and the first compression spring 35 is arranged between the cylinder mounting plate 33 and the lifting plate 31. Specifically, as Figure 5 As shown, the shoulder bar 2 can be made of aluminum profile, and T-slots are formed around the shoulder bar 2, so the connecting plate 1 can be connected to the T-slot on the upper part of the shoulder bar 2 by screws in combination with square nuts. The above-mentioned square nuts slide into the T-slots from the end of the shoulder bar 2, and the above-mentioned screws pass through the connecting plate 1 and are screwed with the above-mentioned square nuts; the magnetic suction cylinder 34 is a product on the market, and a permanent magnet is provided in the cylinder body of the magnetic suction cylinder 34, and the permanent magnet is relatively fixed to the piston of the magnetic suction cylinder 34. When the piston drives the permanent magnet to move to the rear side (inner side) of the suction cup part 341, the permanent magnet can hold the steel parts across the suction cup part 341. When the piston drives the permanent magnet to leave the suction cup part 341, the permanent magnet is away from the steel parts, so that the magnetic force of the permanent magnet on the steel parts is weakened to the point that the magnetic suction cylinder 34 cannot drive the steel parts; the cylinder mounting plate 33 is connected to the tail of the magnetic suction cylinder 34 by corresponding screws. Figure 4 As shown, the lower end of the telescopic rod 32 is mounted to the upper side of the cylinder mounting plate 33 by a screw coaxial with the telescopic rod 32, so that the telescopic rod 32 is coaxial with the piston of the magnetic suction cylinder 34; the telescopic rod 32 vertically passes through the lifting plate 31, and a baffle is installed at the upper end of the telescopic rod 32 to prevent the telescopic rod 32 from falling downward. Figure 2 As shown, the nut 41 is a square nut, and the nut 41 is adapted to slide into the T-slot 21 at the lower part of the stretcher 2, so that the nut 41 cannot rotate in the corresponding T-slot 21, and the pick plate 31 is abutted against the lower side of the stretcher 2, and the mounting screw 4 passes through the pick plate 31 and is threadedly connected to the nut 41, so that the pick plate 31 is relatively fixed to the stretcher 2.

[0022] During the production process, Figure 7 and Figure 8 As shown, the panel 99 (i.e., the air conditioner outdoor unit panel) is transported from the punch press and placed on the conveyor line 97. During this period, the outer surface 991 of the panel 99 is upward, and the conveyor line 97 stops the panel 99 in place. The robot arm 90 is a six-axis robot arm. The robot arm 90 moves the upper hanging pick-and-place device of the utility model and adjusts the posture to make the connecting plate 1 horizontal and the suction cup part 341 of the magnetic suction cylinder 34 downward, as shown in FIG. Figure 3As shown, the robot arm 90 moves the upper hanging picker down, and when the suction cup portion 341 contacts the outer surface 991 of the panel 99, the permanent magnet of the magnetic suction cylinder 34 descends, and the magnetic suction cylinder 34 holds the panel 99. Then the robot arm 90 moves the upper hanging picker and the panel 99 upward away from the conveyor line 97, and then the robot arm 90 moves the upper hanging picker of the utility model and adjusts the posture to make the connecting plate 1 vertical, as shown in FIG. Figure 7As shown, the ventilation hole 9901 on the panel 99 is put on the hook 981 of the suspension chain 98, and then the magnetic cylinder 34 releases the panel 99, and the panel 99 is hung on the hook 981. During this period, the motor used to drive the suspension chain 98 to operate is provided with an encoder, and the position of the hook 981 is detected by the "hanging sensor". The "hanging sensor" feeds back a signal to the robot arm 90, and the robot arm 90 synchronously follows the speed given by the encoder to hang the panel 99 on the hook 981. Since the magnetic cylinder 34 utilizes magnetic force to hold the panel 99, as long as the distance between the permanent magnet in the magnetic cylinder 34 and the panel 99 is within a certain (small) range, the magnetic cylinder 34 can hold the panel 99. In other words, if there is debris on the panel 99 or the panel 99 has microscopic bumps, or there are dents on the panel 99, it will not affect the holding effect of the magnetic cylinder 34 on the panel 99, thereby avoiding the situation where the panel 99 is unstable. That is, the upper hanging pick-up and place device of the utility model has better stability, which is conducive to stable production. Since the magnetic cylinder 34 is suspended by a structure in which the telescopic rod 32 is combined with the first compression spring 35, the amplitude of the downward movement of the connecting plate 1 by the mechanical arm 90 can be appropriately increased during the process of the magnetic cylinder 34 moving downward to hold the panel 99. That is to say, after the suction cup portion 341 contacts the panel 99, the connecting plate 1 and the lifting plate 31 will also move downward by a certain amplitude, so that the telescopic rod 32 slides upward relative to the lifting plate 31, and at the same time, the first compression spring 35 is elastically compressed and deformed, and the elastic restoring force of the first compression spring 35 presses the magnetic cylinder 34 down to the panel 99, ensuring that the magnetic cylinder 34 is in effective contact with the panel 99, thereby avoiding the magnetic cylinder 34 and the panel 99 from being in contact with each other due to errors in the height dimensions of the panel 99 or errors in the operation of the mechanical arm 90. The panel 99 has poor contact and may be twisted and deformed, causing the magnetic cylinder 34 to drive the panel 99 to swing slightly on the conveyor line 97 when it just contacts the panel 99. Since the magnetic cylinder 34 can move upward relative to the connecting plate 1, the remaining magnetic cylinders 34 can follow up and stick to the panel 99. Through the independent movement of each magnetic cylinder 34, the upper-hanging picker and placer can flexibly adapt to the actual deformation of the panel 99; the first compression spring 35 also plays a role in buffering collisions to prevent the magnetic cylinder 34 from denting the panel 99; when the robot arm 90 moves the upper-hanging picker and placer and the panel 99 upward away from the conveyor line 97, the magnetic cylinder 34 will move downward relative to the connecting plate 1 and reset, and the first compression spring 35 will reset elastically.When the external dimensions of the panel 99 change, the mounting screws 4 can be loosened, and then the pick plate 31 can be moved along the extension direction of the T-slot 21 to conveniently and quickly adjust the position of the magnetic head 3. Since the magnetic head 3 is also hung on the stretcher 2 by the mounting screws 4, it can be directly adjusted on the robot arm 90, avoiding the need to remove the upper pick-and-place device from the robot arm 90. After the adjustment is completed, the mounting screws 4 can be retightened. If some types of panels 99 have larger holes, the corresponding magnetic head 3 can also be adjusted so that the magnetic cylinder 34 can avoid the above-mentioned holes.

[0023] Furthermore, if Figure 1 As shown, the two carrying bars 2 are arranged parallel to each other. Figure 2 As shown, the two stretching rods 2 are respectively installed at the two ends of the connecting plate 1, which is conducive to the dispersed arrangement of the four magnetic heads 3, so that the panel 99 can be relatively fixed by the magnetic cylinder 34 over a larger range, thereby preventing the panel 99 from shaking during the transfer by the robot arm 90 and causing the suction cup part 341 to separate from the panel 99.

[0024] Furthermore, if Figure 4 As shown, a first linear bearing 36 is installed on the lifting plate 31, and the telescopic rod 32 is adapted to be slidably connected in the first linear bearing 36, so as to facilitate the smooth movement of the magnetic cylinder 34 relative to the lifting plate 31 and avoid the telescopic rod 32 from getting stuck and causing the magnetic cylinder 34 to dent the panel 99.

[0025] Furthermore, if Figure 1 , Figure 3 and Figure 4 As shown, the upper hanging pick and place device of the utility model further includes a sensing component 5, which includes a slide bar 52, a second compression spring 53, a flange plate 54 and a sliding support plate 55. The flange plate 54 is relatively fixedly connected to the slide bar 52. The slide bar 52 can pass through the flange plate 54 and be relatively fixed by a set screw. The second compression spring 53 is sleeved outside the slide bar 52 (it should be noted that only Figure 4The second compression spring 53 is schematically drawn, the second compression spring 53 is arranged between the flange plate 54 and the sliding support plate 55, the sliding rod 52 is slidably connected to one end of the sliding support plate 55, specifically, the sliding support plate 55 is installed with a second linear bearing 56, the sliding rod 52 is adapted to be slidably connected in the second linear bearing 56, the other end of the sliding support plate 55 is installed and connected to the corresponding carrying rod 2, the connection structure between the sliding support plate 55 and the carrying rod 2 is the same as the connection structure between the lifting plate 31 and the gear lever 2, and the sensing component 5 includes a proximity switch 991 for detecting the outside of the panel 99 51, the proximity switch 51 is installed at the lower end of the slide bar 52, an external thread is formed on the outer wall of the proximity switch 51, the slide bar 52 is a hollow structure, the upper part of the proximity switch 51 can be coaxially inserted into the slide bar 52, the lower end of the slide bar 52 is provided with an end cover, the proximity switch 51 is screwed to the end cover, the wire of the proximity switch 51 can pass through the slide bar 52, the slide bar 52 is relatively fixedly connected with the corresponding telescopic rod 32, that is, the slide bar 52 is parallel to the corresponding telescopic rod 32, and the slide bar 52 and the telescopic rod 32 can slide synchronously. Specifically, the number of the sensing components 5 can be set to one group, such as Figure 1 As shown, the slide bar 52 is relatively fixedly connected to one of the telescopic rods 32. When the magnetic suction cylinder 34 moves down to contact the panel 99 on the conveyor line 97, the magnetic suction cylinder 34 is blocked by the panel 99, so that the telescopic rod 32 moves up relative to the connecting plate 1. Since the slide bar 52 is relatively fixedly connected to the telescopic rod 32, the proximity switch 51 can move up relative to the connecting plate 1 synchronously with the telescopic rod 32, and the second compression spring 53 is elastically compressed and deformed at the same time, so as to avoid the proximity switch 51 from colliding with the panel 99 and being damaged. When the magnetic suction cylinder 34 leaves the panel 99, the second compression spring 53 drives the proximity switch 51 to reset and move. In actual applications, in order to prevent the proximity switch 51 from colliding with the panel 99, the height position of the lower end of the proximity switch 51 should be slightly above the lower end of the magnetic suction cylinder 34. By setting the proximity switch 51, when the robot arm 90 moves the magnetic cylinder 34 downward to contact the panel 99, the panel 99 will trigger the proximity switch 51, and the control system senses the existence of the panel 99 based on the on signal of the proximity switch 51. Since the magnetic cylinder 34 keeps holding the panel 99 during the process of the robot arm 90 transferring the panel 99, the proximity switch 51 keeps the on signal, and the control system can sense that the panel 99 is effectively transferred. When the panel 99 is hung on the hook 981, the magnetic cylinder 34 releases the panel 99, the robot arm 90 resets and moves, and the proximity switch 51 generates a disconnect signal, so that the control system knows that the panel 99 has been detached from the upper hanging pickup.

[0026] Furthermore, if Figure 1 and Figure 4As shown, the upper hanging pick-and-place device of the present invention further includes a synchronous connecting plate 6, one end of which is relatively fixed to the end of the corresponding telescopic rod 32 by a corresponding fastener. Specifically, one end of the synchronous connecting plate 6 covers the upper end surface of the telescopic rod 32, and a screw is passed through the synchronous connecting plate 6 and is screwed to the telescopic rod 32; Figure 1 As shown, the other end corresponding to the synchronous connecting plate 6 is formed with a clamping portion 61, and the clamping portion 61 clamps the sliding rod 52. Specifically, the other end corresponding to the synchronous connecting plate 6 is formed with a clamping hole and a through groove, and the through groove connects the clamping hole and the outer edge of the synchronous connecting plate 6. The upper end of the sliding rod 52 is adapted to be inserted into the above-mentioned clamping hole, and the structures on both sides of the through groove are connected with corresponding screws. The clamping hole is narrowed by the locking force of the screws to clamp the sliding rod 52. The synchronous connecting plate 6 has a simple structure that relatively fixes the telescopic rod 32 and the sliding rod 52, and has a high structural strength. After the screws used to clamp the sliding rod 52 are loosened, the sliding rod 52 can be conveniently adjusted axially so that the proximity switch 51 has a suitable distance from the panel 99.
