Description

Technical Field

[0001] The utility model relates to the technical field of stacking devices, in particular to a double-layer stacking device for split inner units of an air conditioner. Background Art

[0002] After the air conditioner split unit is assembled and packaged on the production line, it is transported to the palletizing position through the production line. The palletizing robot grabs the air conditioner split unit and places it on the plug-in board.

[0003] However, the palletizing robot can only grab and place one air conditioner split unit at a time. When there are a large number of air conditioner split units that need to be grabbed and placed, the palletizing efficiency is limited in the one-by-one grabbing mode, which will lead to a decrease in the overall production efficiency of the processing line.

[0004] Therefore, there is a need for a method for stacking air conditioner split units in double layers so that a palletizing robot can grab and place two air conditioner split units at a time, thereby improving the overall production efficiency of the processing line. Utility Model Content

[0005] In order to overcome the problems existing in the related technology, the purpose of the utility model is to provide a double-layer stacking device for air-conditioning split units, which can stack the first split unit on the top of the second split unit, so that the first split unit and the second split unit form a whole, so that the drum line can transport two split units at a time, and the stacking robot can grab and place two air-conditioning split units at a time, thereby improving the overall production efficiency of the processing line.

[0006] A double-layer stacking device for split units of an air conditioner comprises a lifting mechanism, which is located above a drum line; a plurality of blocking mechanisms are arranged near the drum line, the lifting mechanism is used to drive a first split unit to rise and fall until the first split unit is stacked above a second split unit, and the blocking mechanism is used to block other split units when the lifting mechanism drives the first split unit to move upward.

[0007] When the first split unit moves to the bottom of the lifting mechanism, the blocking mechanism isolates the first split unit from the second split unit. When the lifting mechanism drives the first split unit to move upward, the blocking mechanism descends and the second split unit moves forward. When the second split unit moves to the bottom of the lifting mechanism, the blocking mechanism rises to isolate the second split unit from the third split unit. The lifting mechanism drives the first split unit to descend until the first split unit is stacked on top of the second split unit, at which point the first split unit and the second split unit form a whole. The blocking mechanism descends, and the first split unit and the second split unit move to the palletizing station, so that the roller line can transport two split units at one time, and the palletizing robot can grab and place two air-conditioning split units at one time, thereby improving the overall production efficiency of the processing line.

[0008] In a preferred technical solution of the utility model, the lifting mechanism includes a first lifting cylinder and a suction cup, the bottom of the first lifting cylinder is connected to the suction cup, and the suction cup faces the drum line.

[0009] When the first split internal unit moves to the bottom of the lifting mechanism, the first lifting cylinder descends, the suction cup contacts the top of the first split internal unit, and the suction cup absorbs the first split internal unit.

[0010] In a preferred technical solution of the utility model, the double-layer stacking device for split units of air conditioners further comprises a positioning mechanism, which is arranged close to the lifting mechanism and is used for correcting the position of the split units below the lifting mechanism.

[0011] The positioning mechanism is connected to the roller line. When the first split unit reaches below the lifting mechanism, the positioning mechanism fixes the position of the first split unit, making it convenient for the suction cup of the lifting mechanism to adsorb the first split unit.

[0012] In a preferred technical solution of the utility model, the positioning mechanism includes a positioning fixing end, the positioning fixing end is arranged on the first side of the roller line, and the positioning fixing end is used to clamp the first end of the first split internal machine.

[0013] The positioning fixing end can fix the first end of the first split internal unit when the first split internal unit moves to below the lifting mechanism.

[0014] In a preferred technical solution of the utility model, the positioning and fixing end includes a fixing member and a first clamping member, the fixing member is connected to the first side of the drum line, and the fixing member is provided with a through hole; the first end of the first clamping member is inserted into the through hole, and the second end of the first clamping member is abutted against the first end of the first split machine.

[0015] The first clamp passes through the through hole of the fixing member, the first end of the first clamp extends relative to the through hole of the fixing member, and the second end abuts against the first end of the first split unit. The first clamp can fix the first end of the first split unit.

[0016] In a preferred technical solution of the utility model, the positioning mechanism also includes a positioning movable end, which is arranged on the second side of the roller line, the second side of the roller line is arranged opposite to the first side of the roller line, and the positioning movable end is used to clamp the second end of the first split machine.

[0019] The positioning cylinder can drive the second clamping member to move forward and backward. When there is no need to clamp the second end of the first split unit, the positioning cylinder drives the second clamping member to move in a direction away from the first split unit; when there is a need to clamp the second end of the first split unit, the positioning cylinder drives the second clamping member to move in a direction close to the first split unit until the second clamping member abuts against the second end of the first split unit.

[0020] In a preferred technical solution of the utility model, the double-layer stacking device for the split unit of the air conditioner further comprises a photoelectric detector, which is arranged below the drum line and is used to detect whether the split unit is in place.

[0021] The first split unit moves toward the lifting mechanism. When the first split unit passes the photoelectric detector, it indicates that the first split unit has reached the position. At this time, the first clamping member and the second clamping member are controlled to clamp the first split unit together.

DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0036] Example 1

[0037] like Figure 1 As shown, this embodiment provides a double-layer stacking device for split units of an air conditioner, including a lifting mechanism 1, which is located above the drum line 4; a plurality of blocking mechanisms 2 are arranged near the drum line 4, and the lifting mechanism 1 is used to drive the first split unit 5 to rise and fall until the first split unit 5 is stacked above the second split unit 6, and the blocking mechanism 2 is used to block other split units when the lifting mechanism 1 drives the first split unit 5 to move upward.

[0038] The drum line 4 is arranged between the air-conditioning indoor unit production line and the industrial palletizing robot. The air-conditioning indoor unit production line is used to assemble the air-conditioning split unit. The drum line 4 is used to transport the assembled air-conditioning split unit to the palletizing station. The palletizing robot carries the assembled air-conditioning split unit on the palletizing station and places the assembled air-conditioning split unit on the plug-in board.

[0039] Blocking mechanisms 2 are provided at multiple positions of the drum line 4. The blocking mechanisms 2 are related to the length of the drum line 4. The longer the length of the drum line 4, the more blocking mechanisms 2 there are. In this embodiment, two blocking mechanisms 2 are provided on the drum line 4, wherein one blocking mechanism 2 is located in front of the lifting mechanism 1 and the other blocking mechanism 2 is located behind the lifting mechanism 1. The blocking mechanism 2 is used to block adjacent split machines. For example, the second split machine 6 is located behind the first split machine 5. When the first split machine 5 moves to the bottom of the lifting mechanism 1, the blocking mechanism 2 rises between the first split machine 5 and the second split machine 6 to isolate the first split machine 5 and the second split machine 6. When the lifting mechanism 1 drives the first split machine 5 to rise, the blocking mechanism 2 falls, so that the second split machine 6 moves forward, thereby ensuring that the adjacent first split machine 5 and the second split machine 6 do not interfere with each other during transportation.

[0040] After the blocking mechanism 2 is lowered, the second split machine 6 moves toward the first split machine 5. When the second split machine 6 is located below the lifting mechanism 1, the blocking mechanism 2 rises to isolate the second split machine 6 from the third split machine 10. The lifting mechanism 1 drives the first split machine 5 to move downward until the first split machine 5 is stacked on top of the second split machine 6, so that the first split machine 5 and the second split machine form a whole. The first split machine 5 and the second split machine move forward to the palletizing station, and the palletizing robot grabs the first split machine 5 and the second split machine 6.

[0041] like Figure 4 As shown, the blocking mechanism 2 includes a blocking plate 21 and a second lifting cylinder 22. The bottom of the blocking plate 21 is connected to the second lifting cylinder 22, and the second lifting cylinder 22 drives the blocking plate 21 to move upward or downward. The blocking plate 21 is in a T-shape. When the first split unit 5 reaches the bottom of the lifting mechanism 1, the position of the first split unit 5 is corrected. At this time, the second lifting cylinder 22 drives the blocking plate 21 to rise, and the blocking plate 21 blocks the second split unit 6, thereby separating the first split unit 5 and the second split unit 6. When the lifting mechanism 1 drives the first split unit 5 to move upward, the second lifting cylinder 22 drives the blocking plate 21 to move downward, so that the second split unit 6 moves forward to the bottom of the lifting mechanism 1. When it is necessary to isolate adjacent split units, multiple blocking mechanisms 2 rise synchronously; when it is not necessary to isolate adjacent split units, multiple blocking mechanisms 2 fall synchronously.

[0042] The present embodiment provides a double-layer stacking device for split units of an air conditioner, comprising a lifting mechanism 1, the lifting mechanism 1 being located above the drum line 4; a plurality of blocking mechanisms 2 being arranged near the drum line 4, the lifting mechanism 1 being used to drive the first split unit 5 to rise and fall until the first split unit 5 is stacked above the second split unit 6, and the blocking mechanism 2 being used to block other split units when the lifting mechanism 1 drives the first split unit 5 to move upward. When the first split unit 5 moves to the bottom of the lifting mechanism 1, the blocking mechanism 2 rises to isolate the first split unit and the second split unit 6. When the lifting mechanism 1 drives the first split unit 5 to move upward, the blocking mechanism 2 falls, and the second split unit 6 moves forward. When the second split unit 6 moves to the bottom of the lifting mechanism 1, the blocking mechanism 2 rises to isolate the second split unit 6 and the third split unit 10. The lifting mechanism 1 drives the first split unit 5 to fall until the first split unit 5 is stacked on top of the second split unit 6, at which time the first split unit 5 and the second split unit 6 form a whole. The blocking mechanism 2 descends, and the first split machine 5 and the second split machine 6 move to the palletizing station, so that the roller line 4 can transport two split machines at one time, and the palletizing robot can grab and place two split machines at one time, thereby improving the overall production efficiency of the processing line.

[0045] like Figure 6 As shown, the lifting mechanism 1 includes a first lifting cylinder 11 and a suction cup 12 , the bottom of the first lifting cylinder 11 is connected to the suction cup 12 , and the suction cup 12 faces the drum line 4 .

[0046] In this embodiment, the lifting mechanism 1 includes two first lifting cylinders 11, and two suction cups 12 are provided at the bottom of each first lifting cylinder 11. When the first split machine 5 moves to the bottom of the lifting mechanism 1, the first lifting cylinder 11 descends, and the suction cup 12 contacts the top of the first split machine 5, and the suction cup 12 adsorbs the first split machine 5. The first lifting cylinder 11 moves upward to lift the first split machine 5 upward.

[0047] The double-layer stacking device for split units of an air conditioner further comprises a positioning mechanism 3 , which is arranged close to the lifting mechanism 1 , and is used for correcting the position of the split unit below the lifting mechanism 1 .

[0048] The positioning mechanism 3 is connected to the roller line 4 . When the first split machine 5 reaches below the lifting mechanism 1 , the positioning mechanism 3 fixes the position of the first split machine 5 , making it convenient for the suction cup 12 of the lifting mechanism 1 to adsorb the first split machine 5 .

[0049] The lifting mechanism 1 of this embodiment includes a first lifting cylinder 11 and a suction cup 12, the bottom of the first lifting cylinder 11 is connected to the suction cup 12, and the suction cup 12 faces the drum line 4. The double-layer stacking device of the split unit of the air conditioner also includes a positioning mechanism 3, which is arranged close to the lifting mechanism 1, and the positioning mechanism 3 is used to correct the position of the split unit below the lifting mechanism 1. When the first split unit 5 moves to the bottom of the lifting mechanism 1, the positioning mechanism 3 fixes the position of the first split unit 5. The first lifting cylinder 11 drives the suction cup 12 to descend, and the suction cup 12 adsorbs the first split unit 5. The first lifting cylinder 11 moves upward to lift the first split unit 5 upward.

[0051] like Figure 1 As shown, this embodiment provides a double-layer stacking device for split units of an air conditioner, including a lifting mechanism 1, which is located above the drum line 4; a plurality of blocking mechanisms 2 are arranged near the drum line 4, and the lifting mechanism 1 is used to drive the first split unit 5 to rise and fall until the first split unit 5 is stacked above the second split unit 6, and the blocking mechanism 2 is used to block other split units when the lifting mechanism 1 drives the first split unit 5 to move upward.

[0052] The double-layer stacking device for split units of air conditioners also includes a positioning mechanism 3, which is arranged close to the lifting mechanism 1. The positioning mechanism 3 is used to correct the position of the split units below the lifting mechanism 1, for example, to correct the position of the first split unit, the second split unit and the third split unit.

[0053] like Figure 2 As shown, the positioning mechanism 3 includes a positioning fixing end 31 , and the positioning fixing end 31 is arranged on a first side of the roller line 4 , and the positioning fixing end 31 is used to clamp the first end of the first split inner machine 5 .

[0054] like Figure 3 As shown, the positioning fixing end 31 includes a fixing member 311 and a first clamping member 312, the fixing member 311 is connected to the first side of the drum line 4, and the fixing member 311 is provided with a through hole; the first end of the first clamping member 312 is inserted into the through hole, and the second end of the first clamping member 312 is abutted against the first end of the first split machine 5.

[0055] The side wall of the fixing member 311 is provided with a square or circular through hole, and the first clamping member 312 passes through the through hole of the fixing member 311. The first end of the first clamping member 312 extends relative to the through hole of the fixing member 311, and the second end abuts against the first end of the first split internal unit 5. The shape of the first clamping member 312 is T-shaped. Preferably, a positioning column is provided on the top of the fixing member 311, and the positioning column passes through the through hole on the top of the fixing member 311 and abuts against the first clamping member 312, thereby enhancing the stability of the first clamping member 312 and preventing the first clamping member 312 from being displaced in the through hole of the side wall of the fixing member 311.

[0056] Alternatively, a square or circular blind hole is formed on the side wall of the fixing member 311 , the first end of the first clamping member 312 is inserted into the blind hole, and the second end of the first clamping member 312 abuts against the first end of the first split unit 5 .

[0057] Alternatively, a square or circular through hole is provided on the side wall of the fixing member 311, and a plurality of support members are provided in the fixing member 311. If there are two support members, the two support members abut against the first end of the first clamping member 312 in the vertical direction or the horizontal direction; if there are four support members, the two support members abut against the first end of the first clamping member 312 in both the vertical direction and the horizontal direction. The support member can be a support column or a support block, which is not limited here. The first clamping member 312 can be limited by using the plurality of support members in the fixing member 311.

[0058] The first clamping member 312 is located above the roller line 4 , and the second end of the first clamping member 312 extends along the length direction of the roller line 4 , thereby increasing the contact area between the first clamping member 312 and the first split machine 5 .

[0062] The double-layer stacking device for split units of an air conditioner further comprises a positioning mechanism 3 , which is arranged close to the lifting mechanism 1 , and is used for correcting the position of the split unit below the lifting mechanism 1 .

[0063] like Figure 5 As shown, the positioning mechanism 3 also includes a positioning movable end 32, which is arranged on the second side of the drum line 4, and the second side of the drum line 4 is arranged opposite to the first side of the drum line 4, and the positioning movable end 32 is used to clamp the second end of the first split machine 5.

[0064] The positioning movable end 32 includes a positioning cylinder 321 and a second clamping member 322 . The positioning cylinder 321 is connected to the second side of the drum line 4 . The output shaft of the positioning cylinder 321 is connected to the second clamping member 322 . The second clamping member 322 abuts against the second end of the first split machine 5 .

[0065] The second clamping member 322 may be in a straight line shape or in a straight line shape in the middle, with both ends forming a certain angle with the middle. The extension direction of the second clamping member 322 is the same as the length direction of the drum line 4, thereby increasing the contact area between the second clamping member 322 and the first split machine 5.

[0066] The positioning cylinder 321 can drive the second clamping member 322 to move forward and backward. When it is not necessary to clamp the second end of the first split unit 5, the positioning cylinder 321 drives the second clamping member 322 to move in a direction away from the first split unit 5; when it is necessary to clamp the second end of the first split unit 5, the positioning cylinder 321 drives the second clamping member 322 to move in a direction close to the first split unit 5 until the second clamping member 322 abuts against the second end of the first split unit 5.

When the first split body 5 is in place, the second clamping member 322 clamps the second end of the first split body 5. When the lifting mechanism 1 moves downward until the lifting mechanism 1 contacts the top of the first split body 5, the positioning cylinder 321 drives the second clamping member 322 to move in a direction away from the first split body 5, so that the second clamping member 322 is separated from the first split body 5, and the lifting mechanism 1 drives the first split body 5 to move upward.

The first clamp 312 and the second clamp 322 may abut against the first split unit 5 at the same time, or the first clamp 312 and the second clamp 322 may abut against the first split unit 5 in sequence, which is not limited here. Under the joint action of the first clamp 312 and the second clamp 322, the first split unit 5 is fixed in position.

[0079] After fixing the position of the first split machine 5, the first lifting cylinder 11 drives the suction cup 12 to move from top to bottom until the suction cup 12 adsorbs the top of the first split machine 5. At this time, the positioning cylinder 321 drives the second clamping member 322 to move away from the first split machine 5, so that the second clamping member 322 is separated from the first split machine 5, and the first lifting cylinder 11 drives the first split machine 5 to move upward. When the second split machine 6 approaches the bottom of the second split machine 6, the positioning cylinder 321 drives the second clamping member 322 to move toward the second split machine 6 until the second clamping member 322 abuts against the second end of the second split machine 6. At this time, the first clamping member 312 and the second clamping member 322 jointly fix the position of the second split machine 6, and the first lifting cylinder 11 drives the first split machine 5 to descend until the first split machine 5 is stacked on top of the second split machine 6, so that the first split machine 5 and the second split machine 6 form a whole.

[0080] After the first split machine 5 is stacked on top of the second split machine 6, the blocking mechanism 2 between the second split machine 6 and the palletizing station moves downward, so that the two stacked split machines move toward the palletizing station. When the two stacked split machines reach the palletizing station, the palletizing robot grabs the two stacked split machines.

[0081] The positioning mechanism 3 of this embodiment includes a positioning fixed end 31 and a positioning movable end 32. When the first split unit 5 needs to be fixed, the positioning cylinder 321 drives the second clamping member 322 to move toward the direction close to the first split unit 5, so that the second clamping member 322 abuts against the second end of the first split unit 5. With the cooperation of the first clamping member 312 and the second clamping member 322, the first split unit 5 can be better fixed to prevent displacement after the first split unit 5 is in place.
