[0025] 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.

[0026] Example 1

[0027] like Figure 1-Figure 4 As shown, this embodiment provides an automatic flipping mechanism for a box, including a first belt line 1 and a second belt line 2, wherein the first belt line 1 is located above the second belt line 2; the sides of the first belt line 1 and the second belt line 2 are connected to a flip frame 3, and the flip frame 3 is connected to a flip motor 4; the flip motor 4 is used to drive the flip frame 3 and the box 5 to flip to a first angle when the box 5 reaches the flipping station 6 on the second belt line 2.

[0028] A first belt line 1 and a second belt line 2 are sequentially arranged from top to bottom along the height direction. Both sides of the first belt line 1 are connected to the flip frame 3 , and both sides of the second belt line 2 are connected to the flip frame 3 .

[0029] The flip frame 3 is a rectangle with a hollow part, and the first belt line 1 and the second belt line 2 both extend from the hollow part of the flip frame 3. The first belt line 1 and the second belt line 2 are parallel to each other. In this embodiment, the box body 5 is a packaging box of the air conditioner indoor unit as an example. The height difference between the first belt line 1 and the second belt line 2 can be fixed or adjustable. If the position between the first belt line 1 and the second belt line 2 is fixed, the height difference between the first belt line 1 and the second belt line 2 is equal to the height of the box body 5. If the position between the first belt line 1 and the second belt line 2 is adjustable, and the height difference between the first belt line 1 and the second belt line 2 is greater than the height of the box body 5, the height of the first belt line 1 is adjusted downward using a height adjustment mechanism, that is, the first belt line 1 moves in a direction close to the second belt line 2. If the position between the first belt line 1 and the second belt line 2 is adjustable, and the height difference between the first belt line 1 and the second belt line 2 is less than the height of the box body 5, the height of the first belt line 1 is adjusted upward using a height adjustment mechanism, that is, the first belt line 1 moves in a direction away from the second belt line 2. The height adjustment mechanism can be a retractable lifting rod or a lifting platform, and the first belt line 1 is detachably connected to the lifting rod or the lifting platform.

[0030] A feed roller line 8 is provided on the first side of the second belt line 2. The box 5 moves along the feed roller line 8 toward the second belt line 2. The box 5 moves from the feed roller line 8 to the second belt line 2. The second belt line 2 drives the feed roller line 8 to continue to move forward until the box 5 moves to the flipping station 6. The second belt line 2 stops moving, so that the box 5 is fixed at the flipping station 6. The first belt line 1 abuts against the box 5, the first belt line 1 squeezes the box 5 downward, and the second belt line 2 drags the box 5 upward. Under the joint action of the first belt line 1 and the second belt line 2, the box 5 is clamped to prevent the box 5 from displacement.

[0031] The output shaft of the flipping motor 4 is connected to the flipping frame 3. After the box 5 moves to the flipping station 6, the output shaft of the flipping motor 4 drives the flipping frame 3 to flip clockwise or counterclockwise at a first angle. In this embodiment, the first angle is 180 degrees as an example, so that the first belt line 1 flips to the original position of the second belt line 2, and the second belt line 2 flips to the original position of the first belt line 1, thereby driving the box 5 clamped between the first belt line 1 and the second belt line 2 to flip 180 degrees.

[0032] Since the processes of unpacking and putting the air conditioner split unit into the box have been completed before flipping, the automatic flipping mechanism of the box 5 of the present invention only flips the box 5 and does not need to open both sides of the box 5. Therefore, the automatic flipping mechanism of the box 5 of the present invention can improve the product yield and production efficiency and reduce labor costs without damaging the foam in the box 5.

[0033] This embodiment provides an automatic flipping mechanism for a box 5, comprising a first belt line 1 and a second belt line 2, wherein the first belt line 1 is located above the second belt line 2; the sides of the first belt line 1 and the second belt line 2 are connected to a flip frame 3, and the flip frame 3 is connected to a flip motor 4; the flip motor 4 is used to drive the flip frame 3 and the box 5 to flip to a first angle when the box 5 reaches the flip station 6 on the second belt line 2. When the box 5 is transported to the second belt line 2, the second belt line 2 continues to move forward until the box 5 reaches the flip station 6 on the second belt line 2, at which time the second belt line 2 stops moving forward. The first belt line 1 moves downward, and under the joint action of the first belt line 1 and the second belt line 2, the box 5 is clamped, and then the flip motor 4 drives the flip frame 3 to flip to a first angle. The flip frame 3 can flip clockwise or counterclockwise. After the flip frame 3 flips to the first angle, the first belt line 1 is located below the second belt line 2, the position of the first belt line 1 is the original position of the second belt line 2, and the position of the second belt line 2 is the original position of the first belt line 1. After the flipping is completed, the first belt line 1 drives the box 5 to move forward and transports the box 5 to the discharging structure, such as the discharging roller line 10. The automatic flipping mechanism of the box 5 of the present invention uses the first belt line 1 and the second belt line 2 to clamp the box 5 at the same time, thereby avoiding damage to the foam in the box 5. Improve the yield rate of the product. The automatic flipping mechanism of the box 5 can realize automatic flipping of the box 5, thereby improving production efficiency and reducing labor costs.

[0034] Example 2

[0036] A clamping mechanism is provided on a side of the first belt line 1 away from the second belt line 2 , and the clamping mechanism is arranged toward the second belt line 2 .

[0037] The clamping mechanism includes a clamping cylinder 7 , and the clamping cylinder 7 is used to drive the first belt line 1 to clamp the box body 5 after the box body 5 moves to the flipping station 6 .

[0038] A plurality of clamping cylinders 7 are arranged above the first belt line 1. In this embodiment, two clamping cylinders 7 are arranged as an example. When the box body 5 moves to the flipping station 6, the push rods of the two clamping cylinders 7 extend, and the push rods drive the first belt line 1 to squeeze the box body 5 downward.

[0039] The first belt line 1 applies a downward force to the box body 5, and the second belt line 2 holds the box body 5 upward. The second belt line 2 applies an upward force to the box body 5. Under the joint action of the first belt line 1 and the second belt line 2, the box body 5 is in a force balance state, thereby fixing the box body 5.

[0040] The flip motor 4 drives the flip frame 3 to flip 180 degrees counterclockwise, so that the first belt line 1 flips to the position where the second belt line 2 was originally located, and the second belt line 2 flips to the position where the first belt line 1 was originally located. At this time, the second belt line 2 is located above the first belt line 1. The push rods of the two clamping cylinders 7 drive the first belt line 1 to retract, and then start the first belt line 1. The first belt line 1 starts to move and transports the box 5 on the first belt line 1 to the discharge roller line 10. The flip motor 4 drives the flip frame 3 to flip 180 degrees clockwise, so that the first belt line 1 and the second belt line 2 return to their original positions, that is, the first belt line 1 and the second belt line 2 return to their original positions, and the first belt line 1 is located above the second belt line 2.

[0041] The above operation process is the process of turning over a box 5. The box 5 in this embodiment is a packaging box of an air conditioner indoor unit. After completing the turning process of a box 5, the above process is repeated to turn over the next box 5.

[0042] In this embodiment, a clamping mechanism is provided on the side of the first belt line 1 away from the second belt line 2, and the clamping mechanism is provided toward the second belt line 2. The clamping mechanism includes a clamping cylinder 7, and the clamping cylinder 7 is used to drive the first belt line 1 to clamp the box body 5 after the box body 5 moves to the flipping station 6. Two clamping cylinders are provided above the first belt line 1. When the box body 5 moves to the flipping station 6, the push rods of the two clamping cylinders 7 extend, and the push rods drive the first belt line 1 to squeeze the box body 5 downward. The first belt line 1 applies a downward force to the box body 5, and the second belt line 2 holds the box body 5 upward, and the second belt line 2 applies an upward force to the box body 5. Under the joint action of the first belt line 1 and the second belt line 2, the box body 5 is in a force balance state, thereby fixing the box body 5.

[0043] Example 3

[0044] like Figure 1-Figure 6 As shown, this embodiment provides an automatic flipping mechanism for a box, including a first belt line 1 and a second belt line 2, wherein the first belt line 1 is located above the second belt line 2; the sides of the first belt line 1 and the second belt line 2 are connected to a flip frame 3, and the flip frame 3 is connected to a flip motor 4; the flip motor 4 is used to drive the flip frame 3 and the box 5 to flip to a first angle when the box 5 reaches the flipping station 6 on the second belt line 2.

[0045] A feed roller line 8 is disposed on a first side of the second belt line 2 . A guide structure 9 is disposed on the feed roller line 8 . The feed roller line 8 is used to transport the box 5 to the second belt line 2 .

[0046] A discharge roller line 10 is provided on the second side of the second belt line 2 , and the discharge roller line 10 is used to transport the box body 5 after being turned over.

[0047] The feed roller line 8 and the discharge roller line 10 are respectively arranged on both sides of the second belt line 2 before flipping, and the guide structure 9 is arranged on the side of the feed roller line 8 away from the second belt line 2. The guide structure 9 includes two guide plates arranged opposite to each other, and the guide plates extend along the length direction of the feed roller line 8. The guide plate is divided into two parts, one of which is a horizontal section and the other is a gradient section. The horizontal section is arranged close to the second belt line 2, and the gradient section is arranged away from the second belt line 2. The horizontal section is connected to the gradient section or formed in one piece.

[0048] The gradient section of the guide plate starts from the side close to the second belt line 2 and gradually extends outward to the side away from the second belt line 2, that is, the gradient sections of the two guide plates are arranged opposite to each other, and the closer to the second belt line 2, the smaller the distance between the two gradient sections. The box 5 enters from a larger opening formed between the two gradient sections, and then the opening gradually shrinks. The two guide plates can guide the box 5 on the feed roller line 8 and further limit the box 5.

[0049] After the box 5 is guided by the gradient section of the two guide plates, it enters the area between the horizontal sections of the two guide plates and continues to move toward the second belt line 2 until the feeding roller line 8 transports the box 5 to the second belt line 2. After the box 5 reaches the second belt line 2, the second belt line 2 drives the box 5 to continue to move forward until the box 5 reaches the flipping station 6, and the second belt line 2 stops moving.

[0050] The first belt line 1 moves downward, and under the joint action of the first belt line 1 and the second belt line 2, the box body 5 is clamped. The flip motor 4 drives the flip frame 3 to flip 180 degrees counterclockwise, so that the first belt line 1 flips to the position where the second belt line 2 was originally located, and the second belt line 2 flips to the position where the first belt line 1 was originally located. At this time, the second belt line 2 is located above the first belt line 1.

[0051] After the flipping operation is completed, the flipped box 5 is located above the first belt line 1, and the first belt line 1 is started, and the first belt line 1 drives the flipped box 5 to continue to move forward, and transports the flipped box 5 from the first belt line 1 to the discharge roller line 10. The flipped box 5 continues to move forward with the discharge roller line 10 until the flipped box 5 moves to the discharge position.

[0052] The feed roller line 8 and the discharge roller line 10 are independent of each other, and two driving devices are used to respectively control the feed roller line 8 and the discharge roller line 10. The speeds of the feed roller line 8 and the discharge roller line 10 can be equal or unequal, which is not limited here.

[0053] A feed roller line 8 is provided on the first side of the second belt line 2 of this embodiment, and a guide structure 9 is provided on the feed roller line 8.

A discharge roller line 10 is provided on the second side of the second belt line 2, and the discharge roller line 10 is used to transport the box body 5 after flipping. The feed roller line 8 and the discharge roller line 10 are respectively arranged on both sides of the second belt line 2 before flipping, and the guide structure 9 is arranged on the side of the feed roller line 8 away from the second belt line 2. The guide structure 9 includes two guide plates arranged opposite to each other, and the guide plates extend along the length direction of the feed roller line 8. The guide plate is divided into two parts, one of which is a horizontal section and the other is a gradient section. The horizontal section is arranged close to the second belt line 2, and the gradient section is arranged away from the second belt line 2. The horizontal section is connected to the gradient section or formed in one piece. The box body 5 enters from a larger opening formed between the two gradient sections, and then the opening gradually shrinks. The two guide plates can guide the box body 5 on the feed roller line 8 and further limit the box body 5.

[0054] Example 4

[0055] like Figure 1-Figure 6 As shown, this embodiment provides an automatic flipping mechanism for a box, including a first belt line 1 and a second belt line 2, wherein the first belt line 1 is located above the second belt line 2; the sides of the first belt line 1 and the second belt line 2 are connected to a flip frame 3, and the flip frame 3 is connected to a flip motor 4; the flip motor 4 is used to drive the flip frame 3 and the box 5 to flip to a first angle when the box 5 reaches the flipping station 6 on the second belt line 2.

[0056] The automatic box turning mechanism further comprises a first belt motor 11 , the output shaft of the first belt motor 11 is connected to a first roller 12 , and the outer side of the first roller 12 is connected to the first belt line 1 .

[0057] The automatic box turning mechanism further comprises a second belt motor 13 , the output shaft of the second belt motor 13 is connected to a second roller 14 , and the outer side of the second roller 14 is connected to the second belt line 2 .

[0058] The output shaft of the first belt motor 11 is inserted into the mounting hole of the first roller 12. When the first belt motor 11 is working, the output shaft of the first belt motor 11 rotates, driving the first roller 12 to rotate. The first belt line 1 is wrapped around the outside of the first roller 12, and the first roller 12 rotates, driving the first belt line 1 to rotate.

[0059] The output shaft of the second belt motor 13 is inserted into the mounting hole of the second roller 14. When the second belt motor 13 is working, the output shaft of the second belt motor 13 rotates, driving the second roller 14 to rotate.

[0060] The first belt motor 11 and the second belt motor 13 are independently controlled. When the box 5 moves from the feed roller line 8 to the second belt line 2, the second belt motor 13 is started, and the second belt motor 13 drives the second belt line 2 to move forward, and the box 5 moves forward with the second belt line 2 until the box 5 moves to the flipping station 6. The flipping motor 4 drives the flipping frame 3 to flip 180 degrees counterclockwise, so that the first belt line 1 is located at the position where the second belt line 2 was originally located, and the second belt line 2 is located at the position where the first belt line 1 was originally located. At this time, the box 5 completes the flipping operation. The flipped box 5 is located on the first belt line 1, and the first belt motor 11 is started. The first belt motor 11 drives the first belt line 1 to move forward, and the flipped box 5 moves forward with the first belt line 1. The first belt line 1 transports the flipped box 5 to the discharge roller line 10.

[0061] A blocking mechanism 17 is provided on the side of the second belt line 2 close to the discharge roller line 10, and the blocking mechanism 17 is located between the first belt line 1 and the second belt line 2. The blocking mechanism 17 is used to block the box body 5 from entering the discharge roller line 10 before flipping the box body 5, and to allow the box body 5 to enter the discharge roller line 10 after flipping the box body 5.

[0062] The blocking mechanism 17 is a frame with a baffle, and the height of the blocking mechanism 17 is less than the height of the box 5. When the box 5 is transported from the feed roller line 8 to the second belt line 2, the second belt line 2 drives the box 5 to continue to move forward until the box 5 moves to the flipping station 6. The blocking mechanism 17 is set, if the second belt line 2 does not stop running in time, the box 5 continues to move forward over the flipping station 6, the baffle abuts against the box 5, and the box 5 is limited to prevent the box 5 from moving from the second belt line 2 to the discharge roller line 10 before the flipping operation.

[0063] After the flipping operation of the box body 5 is completed, the second belt line 2 is located at the original position of the first belt line 1, and the blocking mechanism 17 is flipped to the top of the flipped box body 5, and the blocking mechanism 17 no longer blocks the flipped box body 5. The flipped box body 5 can move forward along with the first belt line 1, and the first belt line 1 transports the flipped box body 5 to the discharge roller line 10.

[0064] The automatic flipping mechanism of the box body 5 in this embodiment further includes a first belt motor 11, the output shaft of the first belt motor 11 is connected to a first roller 12, and the outer side of the first roller 12 is connected to the first belt line 1. The automatic flipping mechanism of the box body 5 further includes a second belt motor 13, the output shaft of the second belt motor 13 is connected to a second roller 14, and the outer side of the second roller 14 is connected to the second belt line 2. The first belt motor 11 and the second belt motor 13 are independently controlled. When the box body 5 moves from the feed roller line 8 to the second belt line 2, the second belt motor 13 is started, the second belt motor 13 drives the second belt line 2 to move forward, and the box body 5 moves forward with the second belt line 2 until the box body 5 moves to the flipping station 6. The flipped box body 5 is located on the first belt line 1, the first belt motor 11 is started, the first belt motor 11 drives the first belt line 1 to move forward, the flipped box body 5 moves forward with the first belt line 1, and the first belt line 1 transports the flipped box body 5 to the discharge roller line 10.

[0065] Example 5

In this embodiment, two clamping cylinders 7 are set as an example. The clamping cylinders 7 face the driving plate 16, and the push rods of the two clamping cylinders 7 extend, and the two push rods abut against the driving plate 16. The two push rods apply a downward force to the driving plate 16. Since the fixed plate 15 connects the driving plate 16 and the first belt line 1, the first belt line 1 applies a downward force to the box body 5 between the first belt line 1 and the second belt line 2.

[0071] A driving plate 16 is provided between the first belt line 1 and the clamping cylinder 7, and a fixing plate 15 is used to connect the driving plate 16 and the first belt line 1, so that the clamping cylinder 7 can be prevented from directly contacting the first belt line 1, thereby preventing the clamping cylinder 7 from damaging the first belt line 1. The driving plate 16 and the fixing plate 15 jointly transmit the force provided by the clamping cylinder 7 to the first belt line 1. Before the flipping operation, the driving plate 16 and the fixing plate 15 jointly transmit the force of squeezing the box body 5 downward to the first belt line 1. After the flipping operation, the driving plate 16 and the fixing plate 15 jointly transmit the downward force provided by the clamping cylinder 7 to the first belt line 1, driving the first belt line 1 to retract, and the first belt line 1 drives the flipped box body 5 to move to the discharge roller line 10.

[0072] In this embodiment, a fixing plate 15 is connected to the side of the first belt line 1, and the fixing plate 15 is connected to a driving plate 16; there is a gap between the driving plate 16 and the first belt line 1, and the driving plate 16 is located between the clamping mechanism and the first belt line 1. The driving plate 16 is arranged between the first belt line 1 and the clamping cylinder 7, and the fixing plate 15 is used to connect the driving plate 16 and the first belt line 1, so that the clamping cylinder 7 can be prevented from directly contacting the first belt line 1, thereby preventing the clamping cylinder 7 from damaging the first belt line 1. The driving plate 16 and the fixing plate 15 jointly transmit the force provided by the clamping cylinder 7 to the first belt line 1.
