[0041] Example 1

[0042] This embodiment provides a correction device, such as Figure 1-12As shown, the correction device is used to correct the position of the workpiece 6, and the correction device includes a mounting frame 5 and a conveying component 1, a lifting and rotating component 2, a positioning component 3 and a correction sensing component 4 arranged on the mounting frame 5, the conveying component 1 is located above the lifting and rotating component 2, and the positioning component 3 and the correction sensing component 4 are arranged around the lifting and rotating component 2; after the workpiece 6 reaches the top of the lifting and rotating component 2 after passing through the conveying component 1 and is positioned by the positioning component 3, the lifting and rotating component 2 lifts and rotates the workpiece 6, and at the same time, the position of the workpiece 6 is corrected by the correction sensing component 4.

[0043] The workpiece 6 in this embodiment can be various parts that need to be fixed in position or posture during packaging. For example, in a split air conditioner, the air conditioner connecting pipe is used to connect the indoor unit and the outdoor unit. In the packaging line at the back of the production line, the connecting pipe needs to be placed on both sides of the outdoor unit. Because the joint of the connecting pipe is not wrapped with sponge and the material is relatively hard, in order to prevent the joint of the connecting pipe from scratching the surface of the outdoor unit during the later transportation process, the head of the connecting pipe needs to be placed downward to avoid protruding sheet metal. During the packaging process, the connecting pipe has only one qualified position.

[0044] More specifically, the mounting frame 5 is connected by a plurality of horizontal bars and vertical bars, and is used to support the conveying assembly 1, the lifting and rotating assembly 2, the positioning assembly 3 and the calibration sensing assembly 4. In the space formed by the mounting frame 5, the conveying assembly 1 is located in a relatively middle position of the space, the lifting and rotating assembly 2 is provided above the conveying assembly 1, and the positioning assembly 3 and the calibration sensing assembly 4 are provided on both sides of the conveying assembly 1. The conveying assembly 1 is used to convey the workpiece 6, the lifting and rotating assembly 2 is used to lift the workpiece 6 and enable the workpiece 6 to rotate, the positioning assembly 3 is used to position the workpiece 6, and the calibration sensing assembly 4 is used to make the posture and position of the workpiece 6 meet the requirements by sensing, thereby achieving qualified conveying of the workpiece 6. In this embodiment, the workpiece 6 is first conveyed by the conveying assembly 1, and when it is conveyed to the top of the lifting and rotating assembly 2, the positioning assembly 3 positions it; the lifting and rotating assembly 2 rises and connects with the workpiece 6; then the calibration sensing assembly 4 senses the position and posture of the workpiece 6, and if the position and posture are unqualified, the lifting and rotating assembly 2 drives the workpiece 6 to rotate until its posture and position meet the requirements. The correction device provided in this embodiment adopts a mechanical correction method, combined with the external shape of the workpiece 6. Since the posture of the workpiece 6 has only one qualified position, accurate correction of the workpiece 6 can be achieved, avoiding the technical problem of inadequate correction and quality abnormality caused by traditional manual visual correction.

[0045] In a specific embodiment, Fig. 9As shown, the lifting and rotating assembly 2 includes a lifting unit 21, a rotating unit 22 and an adsorption unit 23. The lifting unit 21 is connected to the adsorption unit 23 to drive the adsorption unit 23 to move up and down, and the rotating unit 22 is connected to the adsorption unit 23 to drive the adsorption unit 23 to rotate; the workpiece 6 can be adsorbed and connected to the adsorption unit 23 during calibration.

[0046] More specifically, the lifting and rotating assembly 2 has two functions. The first function is to lift the workpiece 6 from the conveying assembly 1 so that it can be flush with the positioning assembly 3, and then realize positioning through the positioning assembly 3; the second function is to drive the workpiece 6 to rotate so that the workpiece 6 is adjusted to a qualified posture and position. Therefore, the lifting and rotating assembly 2 includes a lifting unit 21 and a rotating unit 22. In addition, during the rotation process, in order to prevent the workpiece 6 from being affected by centrifugal force and causing position deviation, the present embodiment also provides an adsorption unit 23. Before the rotation, the adsorption unit 23 can firmly adsorb the workpiece 6 to make its rotation more stable.

[0047] In a specific embodiment, Fig. 9 As shown, the lifting unit 21 includes a first cylinder 211, a connecting plate 212 and a transmission rod 213, the output end of the first cylinder 211 is connected to the connecting plate 212, the transmission rod 213 passes through the connecting plate 212, and one end of the transmission rod 213 is connected to the adsorption unit 23, and the other end of the transmission rod 213 is fixed by a bearing 214, and the bearing 214 is located in a bearing seat 215. More specifically, the first cylinder 211 is fixed on the mounting frame 5, and its output end is connected to the connecting plate 212, and the transmission rod 213 passes through the connecting plate 212 and then is connected to the adsorption unit 23 at one end, and the other end is fixed by a bearing 214. In this embodiment, after the first cylinder 211 is working, it can push the adsorption unit 23 to rise through the connecting plate 212 and the transmission rod 213, and then cooperate with the workpiece.

[0048] In a specific embodiment, Fig. 9 As shown, the rotating unit 22 includes a motor 221, a synchronous belt 222, a driving wheel 223 and a driven wheel 224. The motor 221 passes through the connecting plate 212 and is connected to the driving wheel 223. The driving wheel 223 and the driven wheel 224 rotate synchronously through the synchronous belt 222. The driven wheel 224 is connected to the adsorption unit 23. In the specific use process, the motor 221 is a servo motor. The servo motor rotates, thereby causing the driving wheel 223 to rotate. The driving wheel 223 drives the driven wheel 224 to rotate through the synchronous belt 222, thereby driving the adsorption unit 23 connected to the driven wheel 224 to rotate, so that the workpiece 6 adsorbed on the adsorption unit 23 can be driven to rotate so that its position and posture meet the requirements.

[0049] In a specific embodiment, Figure 9-12 As shown, the adsorption unit 23 includes a turntable 231, a suction cup 232 and a connecting rod 233. There are multiple suction cups 232 and the connecting rod 233, and the multiple suction cups 232 are evenly distributed on the turntable 231 through the corresponding connecting rods 233, and are all fixed by nuts 234. The turntable 231 is a circular structure. On the upper surface of the circular structure, a circle of suction cups 232 is arranged along the circumference. The bottom of the suction cup 232 is connected to the connecting rod 233. The connecting rod 233 passes through the turntable 231 and is fixed by nuts 234. In this embodiment, the shape of the turntable 231 and the arrangement of the suction cups 232 are set for the air conditioning connecting pipe. If the workpiece 6 is of other shapes or structures, the shape of the turntable 231 and the arrangement of the suction cups 232 can be adaptively adjusted according to needs.

[0050] In a specific embodiment, in order to better position the workpiece 6, at least two groups of the positioning components 3 are provided, and at least two groups of the positioning components 3 are evenly distributed on both sides of the lifting and rotating components 2. In one embodiment, four groups of positioning components 3 are provided, two of which are located on one side of the lifting and rotating components 2, and the other two are located on the other side of the lifting and rotating components 2. In this way, when the lifting and rotating components 2 drive the workpiece 6 to rise to the specified position, the four groups of positioning components 3 position the workpiece 6 from four directions, making the positioning more accurate.

[0051] like Figure 7 As shown, the positioning assembly 3 includes a second cylinder 31 and a second cylinder mounting plate 32, and the second cylinder 31 is arranged on the mounting frame 5 through the second cylinder mounting plate 32. In addition, the positioning assembly 3 also includes a follower bearing 33 and a bearing connector 34, and the bearing connector 34 is located at the end of the second cylinder 31, and the output end of the second cylinder 31 passes through the bearing connector 34. The follower bearing 33 is movably arranged at the output end of the second cylinder 31 and can rotate with the workpiece 6. In this way, after adopting the above structure, when the workpiece 6 rotates with the jacking and rotating assembly 2, the follower bearing 33 in contact with the workpiece 6 will also rotate accordingly, avoiding the end of the second cylinder 31 from causing wear to the workpiece 6.

[0052] In a specific embodiment, Figure 3 As shown, the calibration sensing assembly 4 includes a first calibration unit 41, which is located at a first position and is used to sense the position of the workpiece 6. That is, when the workpiece 6 rotates following the lifting and rotating assembly 2, when the first calibration unit 41 senses the workpiece 6, it proves that the position and posture of the workpiece 6 meet the requirements, otherwise, the requirements are not met and the workpiece 6 needs to continue to rotate.

[0053] The calibration sensing assembly 4 also includes a second calibration unit 42, which is located at the second position, and is used for when the workpiece 6 moves to the second position, the lifting and rotating assembly 2 rotates a fixed angle to move the workpiece 6 to the first position; wherein the first position and the second position differ by 180°. Specifically, in the process of the workpiece 6 following the rotation of the lifting and rotating assembly 2, there are three situations. The first is that the first calibration unit 41 senses the workpiece 6, which proves that the position and posture of the workpiece 6 meet the requirements, and the workpiece 6 needs to stop rotating at this time; the second is that the second calibration unit 42 senses the workpiece 6, which proves that the workpiece 6 can reach a qualified position and posture after rotating 180° and stopping; the third is that neither the first calibration unit 41 nor the second calibration unit 42 senses the workpiece 6, and at this time the workpiece 6 needs to continue rotating until it is sensed by the first calibration unit 41 or the second calibration unit 42.

[0054] In a specific embodiment, Figure 8 As shown, the first correction unit 41 includes a third cylinder 411, a third cylinder mounting plate 412, a travel switch mounting plate 413 and a travel switch 414. The third cylinder 411 is arranged on the third cylinder mounting plate 412, the output end of the third cylinder 411 is connected to one end of the travel switch mounting plate 413, and the other end of the travel switch mounting plate 413 is connected to the travel switch 414; the second correction unit 42 and the first correction unit 41 have the same structure. In the specific use process, the third cylinder 411 can control the movement of the travel switch 414 through the travel switch mounting plate 413. In the transportation and positioning stage of the workpiece 6, the third cylinder 411 is in a contracted state, and in the correction stage of the workpiece 6, the third cylinder 411 is in an extended stage. The relevant parameters of the third cylinder 411 are set in advance so that the travel switch 414 can just contact the specified position of the workpiece 6 after it is extended.

[0055] In a specific embodiment, Figure 1 As shown, the conveying assembly 1 includes a driving unit, a conveying line 11 and a sensor 12. The driving unit is connected to the conveying line 11 to drive the conveying line 11 to rotate. The sensor 12 is arranged at the lifting and rotating assembly 2 to control the driving unit to stop working when the conveying line 11 drives the workpiece 6 to move directly above the lifting and rotating assembly 2. The sensor 12 is a reflective sensor.

[0056] The working process of the calibration device provided in this embodiment is as follows:

[0057] Assume that workpiece 6 is a connecting pipe; Figure 4-6As shown, first the driving unit works, and the connecting pipe is conveyed through the conveying line 11. During the conveying process, when the sensor 12 detects the connecting pipe, the conveying line 11 stops conveying, that is, the driving unit stops working; then the second cylinder 31 works, the follower bearing 33 is locked on the bearing connector 34, and the bearing connector 34 is locked on the second cylinder 31. The second cylinder 31 extends to drive the follower bearing 33 to contact the connecting pipe. The second cylinder 31 in four directions drives the four follower bearings 33 to extend and contact the connecting pipe at the same time, so as to realize the positioning of the connecting pipe; then the first cylinder 211 works, and the suction cup 232 generates suction to suck and lift the connecting pipe; when the connecting pipe is positioned and lifted, the third cylinder 411 works, so that the travel switch 414 extends into place, and at the same time the positioning assembly 3 returns to its original position. Then the servo motor rotates, and drives the transmission rod 213 to rotate through the driving wheel 223, the synchronous belt 222 and the driven wheel 224, so that the connecting pipe can be rotated in the end. During the rotation process, when the travel switch 414 of the first calibration unit 41 senses the workpiece 6, it proves that the position and posture of the workpiece 6 meet the requirements, and the workpiece 6 stops rotating. When the travel switch 414 of the second calibration unit 42 senses the workpiece 6, the workpiece 6 rotates 180° and stops. Finally, the calibration sensing assembly 4 returns to its original position, and the connecting pipe falls on the conveyor line 11 and continues to be conveyed forward.

[0058] This embodiment adopts a mechanical connecting pipe correction device, which can more accurately determine the posture position of the connecting pipe through sensor detection, effectively solving the position deviation problem, and canceling visual detection, avoiding the technical problem of inadequate correction through manual visual correction, thereby causing quality abnormalities.
