Description

Technical Field

[0001] The invention belongs to the technical field of air conditioner production devices and relates to an automatic transport device for air conditioner production. Background Art

[0002] Air conditioners are an indispensable electrical appliance in modern life. They provide comfortable temperature and air quality for people's living and working environment and are widely used in homes, offices, factories and other places. As people's living standards improve, the demand for air conditioners is increasing, and the performance and quality requirements for air conditioners are also getting higher and higher.

[0003] The production of air conditioners involves multiple links, mainly including raw material procurement, parts processing, assembly, testing and packaging. Air conditioners are usually produced and processed using assembly line operations, and all links from processing to assembly are transported by assembly line. After the assembly of the air conditioner outdoor unit is completed, it is transported by assembly line operations, and a manipulator is set at an appropriate position on the assembly line. The assembled finished air conditioner outdoor unit is grabbed from the assembly line and transported to the wooden pallet by a grabbing mechanism, and then transferred. The traditional grabbing mechanism generally directly uses the cylinder clamping mode to clamp and transport the air conditioner outdoor unit. The cylinder clamping method is not conducive to the control of the clamping force. If the clamping force is too large, it is easy to cause the air conditioner outdoor unit to be clamped and damaged. If the clamping force is not enough, the air conditioner outdoor unit is easy to fall during the transportation process, directly causing damage. Therefore, we propose an automatic handling device for air conditioner production to solve the above-mentioned problems. Summary of the invention

It should be noted that the illustrations provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] Example 1

[0036] like Figure 1 - Figure 3As shown, an automatic handling device for air-conditioning production includes a hanging plate 1 connected to a mechanical arm, and the hanging plate 1 is controlled by the mechanical arm to transfer horizontally and move up and down. The traditional mechanical arm is a prior art, and those skilled in the art can know its principle when designing and installing it. As long as the mechanical arm can realize the horizontal adjustment, angle adjustment and lifting adjustment of the hanging plate 1, it can be used in the present invention, and no specific details are given here; the two sides of the bottom of the hanging plate 1 are symmetrically slidably connected with two mounting seats 2, and the bottom of the hanging plate 1 is provided with a first adjustment mechanism for adjusting the distance between the two mounting seats 2, so as to adapt to different widths The air conditioner outdoor unit, the first adjustment mechanism includes a screw motor 3 and a fixed block 8 fixedly connected to the bottom of the hanging plate 1, a screw 12 is fixedly connected to the output shaft of the screw motor 3, and the other end of the screw 12 is rotatably connected to one side of the fixed block 8, the outer wall of the screw 12 is provided with a nut block 13 slidably connected to the bottom of the hanging plate 1, and the bottom two sides of the nut block 13 are symmetrically rotatably connected to two first connecting rods 14, and the two sides of the two mounting seats 2 close to each other are slidably connected to the connecting block 10, and the other ends of the two first connecting rods 14 are respectively rotatably connected to the tops of the two connecting blocks 10. Starting the screw motor 3 to drive the screw 12 to rotate can drive the nut block 13 to move, and through the cooperation of the two first connecting rods 14 and the connecting block 10, the two mounting seats 2 can be driven to slide at the bottom of the hanging plate 1, so that the two mounting seats 2 are close to or away from each other, thereby adjusting the distance between the two mounting seats 2.

[0037] The bottom of the two mounting seats 2 are provided with two transport arms 4 symmetrically sliding in pairs, and the bottom of the mounting seats 2 is provided with a second adjustment mechanism for adjusting the spacing between the two transport arms 4, which is used to adapt to air conditioner outdoor units of different thicknesses. The air conditioner outdoor unit can be transported from both sides thereof through four transport arms 4. The second adjustment mechanism includes a fixing plate 16 symmetrically fixedly connected to the edges of both sides of the bottom of the mounting seat 2, and the two fixing plates 16 are rotatably connected to the same bidirectional screw 25 on the side close to each other, and the two transport arms 4 are respectively threadedly sleeved on the positive and negative thread segments of the bidirectional screw 25, and the outer wall of the bidirectional screw 25 is fixedly sleeved with a rotating handle 36 located between the two transport arms 4. By adjusting the spacing between the two mounting seats 2, the spacing between the two groups of transport arms 4 can be adjusted, so as to adapt to air conditioner outdoor units of different widths and facilitate the transport of air conditioner outdoor units of different models; by rotating the rotating handle 36 to drive the bidirectional screw 25 to rotate, the two transport arms 4 can be driven to move closer or farther from each other, thereby adjusting the spacing between the two transport arms 4, so as to adapt to air conditioner outdoor units of different thicknesses and facilitate the transport of air conditioner outdoor units of different models.

[0038] The present invention can be used in the field of automatic transportation in air-conditioning production, and can also be applied to other fields of the present invention.

[0039] Example 2

[0040] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 8 As shown, a cylindrical groove 11 is provided at the top of the transport arm 4, and a rotating rod 30 is passed through the bottom inner wall of the cylindrical groove 11. The bottom end of the rotating rod 30 passes through the bottom of the transport arm 4 and is fixedly sleeved with a collar 32. The outer wall of the collar 32 is annular and equidistantly fixed with three receiving blocks 33 for supporting the air conditioner outdoor unit. According to the model of the air conditioner outdoor unit to be transported, the distance between the two mounting seats 2 and the distance between the two transport arms 4 are adjusted respectively. Since the assembled air conditioner outdoor units are automatically transported through the assembly line, the robot arm installed on the assembly line can be controlled at this time so that the entire transport device is transferred to the top of the air conditioner outdoor unit under the control of the robot arm, and then the hanging plate 1 is controlled to move downward so that the entire transport device is docked with the air conditioner outdoor unit. At this time, the angular positions of the three receiving blocks 33 are as shown in FIG. Fig.10 As shown, they are all located at the outer side of the bottom of the air-conditioning outdoor unit. Since a base for installation is provided at the bottom of the air-conditioning outdoor unit, a certain gap is reserved between the bottom of the air-conditioning outdoor unit and the conveying table or the placement table, and the positions of the three receiving blocks 33 correspond to the gaps. When the entire transport device is docked with the air-conditioning outdoor unit, the angular positions of the three receiving blocks 33 will change, and they will rotate 60 degrees at the same time, so that one of the receiving blocks 33 is rotated to the bottom of the air-conditioning outdoor unit, and its position is as shown in FIG. Fig.11 As shown, finally, the mechanical arm controls the hanging plate 1 to move upward, and at this time, the bottom of the air-conditioning outdoor unit can be supported by the receiving block 33, thereby realizing the transportation of the air-conditioning outdoor unit.

[0041] In one aspect of the present embodiment, the top end of the cylindrical groove 11 is rotatably penetrated by an inner spline shaft tube 15, the bottom end of the inner spline shaft tube 15 is slidably penetrated by an outer spline shaft 29, and the bottom end of the outer spline shaft 29 is fixedly connected to the top of a rotating rod 30, the outer wall of the bottom end of the inner spline shaft tube 15 is rotatably sleeved with a fixing ring 27 fixedly connected to the cylindrical groove 11, the outer wall of the rotating rod 30 is rotatably sleeved with a sliding ring 34 slidably connected to the cylindrical groove 11, and a second spring 35 sleeved on the outer wall of the rotating rod 30 is fixedly connected between the sliding ring 34 and the fixing ring 27. When the inner spline shaft tube 15 rotates, the outer spline shaft 29 can be driven to rotate, and the rotating rod 30 can be driven to rotate, thereby driving the ring 32 to rotate, thereby driving the receiving block 33 to rotate to achieve the effect of angle conversion and adjustment; when the receiving block 33 is located below the bottom of the air-conditioning outdoor unit, the air-conditioning outdoor unit can be lifted and carried; when the receiving block 33 is located outside the bottom of the air-conditioning outdoor unit, the entire carrying device can be put down and docked with the air-conditioning outdoor unit, or after the carrying is completed, the entire carrying device can be taken out upwards; By setting the second spring 35, when the receiving block 33 is not subjected to the pressure of the air-conditioning outdoor unit, the receiving block 33 can correspond to the gap position at the bottom of the air-conditioning outdoor unit when it is lowered. When the air-conditioning outdoor unit is lifted for transportation, the receiving block 33 can move downward and drive the rotating rod 30 to move downward through the sleeve ring 32, thereby driving the sliding ring 34 to move downward and stretching the second spring 35. The sliding ring 34 can limit the downward movement of the rotating rod 30, and the rotating rod 30 simultaneously drives the outer spline shaft 29 to slide downward in the inner spline shaft tube 15.

[0042] Example 3

[0043] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 8As shown, the interior of the mounting seat 2 is a hollow structure, and a sliding plate 17 is slidably connected to the interior of the mounting seat 2. Two sliders 21 are symmetrically slidably connected to one side of the sliding plate 17, and the two sliders 21 are respectively slidably connected to the top of the corresponding carrying arm 4. The bottom of the mounting seat 2 is symmetrically provided with two moving holes 26 used in conjunction with the two sliders 21, one side of the two sliders 21 is fixedly connected with an L-shaped rod 23, one side of the two L-shaped rods 23 is fixedly connected with a first rack 24, the top end of the inner spline shaft tube 15 extends to the interior of the mounting seat 2 and is fixedly sleeved with a one-way bearing 19, and a gear 22 meshing with the corresponding first rack 24 is fixedly sleeved on the one-way bearing 19, and the bottom of the mounting seat 2 is symmetrically provided with two bar holes 18 used in conjunction with the two inner spline shaft tubes 15. By setting the strip hole 18 and the moving hole 26, when adjusting the distance between the two transport arms 4, the inner spline shaft tube 15 can be moved in the strip hole 18, so that the two sliders 21 can slide on the sliding plate 17 while moving in the moving hole 26, and the slider 21 can drive the L-shaped rod 23 to move synchronously, and make the first rack 24 move together with the gear 22 and always keep in meshing state; when the sliding plate 17 moves, the first rack 24 can be driven to move by the L-shaped rod 23, and then the gear 22 can be driven to rotate by the meshing movement with the gear 22, and the one-way bearing 19 can be set. , when the sliding plate 17 slides toward the gear 22, the inner spline shaft tube 15 is driven to rotate through the one-way bearing 19, and then the rotating rod 30 is driven to rotate through the outer spline shaft 29, so that the receiving block 33 is driven to rotate and adjust through the collar 32; when the sliding plate 17 slides away from the gear 22, the inner spline shaft tube 15 will not be driven to rotate through the one-way bearing 19, and the gear 22 can only rotate with the movement of the first rack 24, so the receiving block 33 will not be driven to rotate; when the sliding plate 17 slides back and forth, it can also drive the slider 21 to move in the moving hole 26.

[0044] In one aspect of the present embodiment, two groups of slide bars 6 are fixedly connected to the bottom inner wall of the mounting seat 2, and the number of slide bars 6 in each group is at least two. The same limit plate 7 is slidably sleeved on each group of slide bars 6, and the outer walls of the plurality of slide bars 6 are sleeved with a first spring 9, and the two ends of the first spring 9 are respectively fixedly connected to the bottom of the limit plate 7 and the bottom of the inner wall of the mounting seat 2, and the tops of the two limit plates 7 are fixedly connected to the sliding column 5, and the tops of the two sliding columns 5 slide through the top of the mounting seat 2 and are slidably connected to the bottom of the hanging plate 1, and the bottoms of the two limit plates 7 are rotatably connected to the second connecting rod 20, and the other ends of the two second connecting rods 20 are rotatably connected to the side of the sliding plate 17 away from the slider 21. Fig.10As shown, when the air-conditioning outdoor unit is not being transported, the hanging plate 1 and the mounting seat 2 are slidably connected by the sliding column 5, and there is a certain height interval. When the entire transport device is connected to the air-conditioning outdoor unit, under the restricted effect of the conveying table or the placing table, the receiving block 33 corresponds to the bottom gap of the air-conditioning outdoor unit and cannot continue to move downward, and the hanging plate 1 will continue to move downward for a distance until it contacts the top of the mounting seat 2; during the downward movement of the hanging plate 1, the sliding column 5 will be driven to move downward, thereby squeezing the limit plate 7 to slide downward on the slide rod 6, and squeezing the first spring 9, and at the same time, the sliding plate 17 can be driven to slide through the second connecting rod 20, thereby driving the slider 21 to move closer to the gear 22; when the hanging plate 1 contacts the mounting seat 2, the sliding plate 17 moves to the maximum stroke, and the three receiving blocks 33 are rotated 60 degrees, so that one of the receiving blocks 33 rotates to the bottom of the air-conditioning outdoor unit, as shown in FIG. Fig.11 As shown, the mechanical arm then controls the hanging plate 1 to move upward, and at the same time drives the sliding column 5 upward, so that the limit plate 7 and the first spring 9 are reset synchronously, and the sliding plate 17 is driven to reset and move through the second connecting rod 20, thereby driving the slider 21 to move away in the direction of the gear 22. During this process, the one-way bearing 19 is set so that the receiving block 33 will not be driven to rotate, so that it maintains the supporting state for the air conditioner outdoor unit. When the hanging plate 1 continues to move upward, it can drive the mounting seat 2 to move upward, and then drive the transport arm 4 to move upward, and finally lift the air conditioner outdoor unit upward through the receiving block 33 to achieve the transport effect. When the air conditioner outdoor unit is transported to the transfer pallet, similarly, the receiving block 33 contacts the pallet, and the hanging plate 1 continues to move downward with the mechanical arm, and also drives the sliding column 5 to move downward, and pushes the sliding plate 17 to move, thereby driving the three receiving blocks 33 to rotate 60 degrees again, so that the three receiving blocks 33 rotate again to the position as shown in the figure. Fig.10 The states shown are all located at the bottom outer side of the air conditioner outdoor unit. At this time, the hanging plate 1 continues to move upward through the mechanical arm, and the receiving block 33 will not rotate again, so that the entire transport device can be moved out to transport the next air conditioner outdoor unit.

[0045] Example 4

[0046] This embodiment is a further improvement of the previous embodiment: Figure 8 As shown, the bottom end of the rotating rod 30 is rotatably connected to the chassis 31. Through the arrangement of the chassis 31, when the air conditioner outdoor unit is docked or transported to the pallet, the chassis 31 can be brought into contact with the conveying table or the placing table, and a certain downward pressure is generated during the downward movement of the hanging plate 1. Therefore, its force acts between the chassis 31 and the table, which makes the rotation of the receiving block 33 smoother.

[0047] Example 5

[0048] This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig. 9 As shown, the interior of the transport arm 4 is provided with an installation cavity 28, the interior of the installation cavity 28 is vertically rotatably connected with a rotating rod 37, the outer wall of the rotating rod 37 is fixedly connected with a stop plate 40 for limiting the position of the two sides of the air conditioner outdoor unit, and a clearance hole 44 is provided on one side of the transport arm 4, and one side of the stop plate 40 passes through the clearance hole 44 and extends outward. When the air conditioner outdoor unit is lifted and transported by the receiving block 33, the other two sides of the air conditioner outdoor unit can be simultaneously protected by the stop plate 40 to prevent the air conditioner outdoor unit from falling due to unstable center of gravity during transportation.

[0049] In one aspect of the present embodiment, an L-shaped block 38 is fixedly connected to the outer wall of the sliding ring 34, a through hole 41 is opened between the mounting cavity 28 and the cylindrical groove 11, one side of the L-shaped block 38 extends through the through hole 41 into the mounting cavity 28 and is rotatably connected to a third connecting rod 43, a second rack 42 is slidably connected to the inner wall of one side of the mounting cavity 28, and one end of the third connecting rod 43 is rotatably connected to the top of the second rack 42, and an incomplete gear 39 meshing with the second rack 42 is fixedly sleeved on the outer wall of the rotating rod 37. When the receiving block 33 lifts the air conditioner outdoor unit, it will be affected by the gravity of the air conditioner outdoor unit, driving the receiving block 33 to move downward, and driving the rotating rod 30 to move downward through the collar 32, and the rotating rod 30 drives the sliding ring 34 to slide downward and stretch the second spring 35, and at the same time drives the L-shaped block 38 to move downward in the through hole 41, and drives the second rack 42 to move through the third connecting rod 43, and then drives the incomplete gear 39 to rotate a certain angle, so that the stop plate 40 is driven to rotate a certain angle in the clearance hole 44 through the rotating rod 37, so that the stop plate 40 contacts one side of the air conditioner outdoor unit; Fig.11 As shown, a plurality of abutment plates 40 are used to respectively block and protect the two sides of the air-conditioning outdoor unit, so that during the process of carrying the air-conditioning outdoor unit, it can have a certain protective effect and prevent the air-conditioning outdoor unit from falling and being damaged.

[0050] However, as is well known to those skilled in the art, the working principle and wiring method of the screw motor 3 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
