[0042] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any changes in the device, method, or function made by a person skilled in the art based on the embodiments are all within the protection scope of the present invention.

It is understood that, depending on the placement of the product, the terms of relative spatial positions may be intended to include different orientations other than those shown in the drawings, and should not be construed as limitations on the claims. In addition, the descriptor "horizontal" used herein is not completely equivalent to being perpendicular to the direction of gravity, and a certain angle of inclination is allowed.

[0044] like Figure 1-2 As shown, the door body 100 of the refrigeration equipment includes an insulating glass 110 and a plurality of frames 120 arranged around the insulating glass 110. The frames 120 can be bonded around the insulating glass 110 by glue (such as silicone glue). Two adjacent frames 120 can be connected by angle brackets 130. The angle brackets 130 are generally L-shaped and include a first connecting portion and a second connecting portion that are relatively vertical. The first connecting portion and the second connecting portion can be connected to a frame 120 respectively by fasteners such as screws. In this way, the plurality of frames 120 can be connected and fixed as a whole by using a plurality of angle brackets 130. Specifically, a first connecting hole 121 for connecting with the angle bracket 130 is provided on one side of the frame 120 in the thickness direction. The angle bracket 130 is provided with a second connecting hole 131 that matches the first connecting hole 121. In this embodiment, the one side of the door body 100 in the thickness direction where the first connecting hole 121 is located is defined as the back side of the door body 100, and the other side is defined as the front side of the door body 100. The first connection hole 121 is arranged upward, that is, the back side of the door body 100 is arranged upward, and vice versa, the front side of the door body 100 is arranged upward. The frame 120 and the corner bracket 130 can be fixedly connected by connecting the first connection hole 121 and the second connection hole 131 with a fastener.

[0045] like Figure 3 As shown, an embodiment of the present invention provides an assembly line 200 of a refrigeration equipment door body, comprising a conveying device 10 extending along a first direction, a centering assembly device 20 and a flipping device 30 arranged on a conveying path of the conveying device 10. The conveying device 10 is used to convey the insulating glass 110 and the frame 120 along its extension direction, and to convey the door body 100 after the insulating glass 110 and the frame 120 form the door body 100.

[0046] like Figure 4-7As shown, the centering assembly device 20 includes a first lifting frame 21, a first driving member 22 for driving the first lifting frame 21 to move up and down, the first lifting frame 21 includes a bearing plate 211 located above it, and a plurality of clamping blocks 212 arranged on the bearing plate 211, and the plurality of clamping blocks 212 are surrounded to form a clamping space for clamping the door body 100. The centering assembly device 20 also includes a plurality of vertically arranged top rods 23, and a second driving member 24 for driving the plurality of top rods 23 to move up and down relative to the bearing plate 211. Under the drive of the second driving member 24, the plurality of top rods 23 have a first position in which their top surfaces are higher than the clamping blocks 212, and a second position in which their top surfaces are lowered to below the top surface of the bearing plate 211.

[0047] After the frame 120 is bonded to the hollow glass 110 around to form the door body 100, it takes some time for the glue to solidify to obtain sufficient bonding strength. When the door body 100 is in the clamping space, multiple clamping blocks 212 can clamp the door body 100 around (i.e., the side edges of the frame 120), adjust the door body 100 to a preset shape and maintain it for a preset length of time to allow the glue to solidify, so that the door body 100 can be formed in a preset shape.

[0048] During specific operation, the insulating glass 110 is placed on the conveying device 10 for conveying. When it is conveyed to the centering assembly device 20, the push rod 23 rises to the first position to lift the insulating glass 110 from the conveying device 10, and the carrying plate 211 rises to a position higher than the conveying device 10. At this time, the insulating glass 110 is higher than the clamping block 212. The operator can conveniently bond the frame 120 coated with glue to the surrounding of the insulating glass 110 to assemble and form the door body 100. After the bonding is completed, the push rod 23 drops to the second position to make the door body 100 fall on the carrying plate 211. Then, the clamping space formed by the multiple clamping blocks 212 can define the shape of the door body 100. After the door body 100 is clamped by the clamping blocks 212 for a period of time, the glue evaporates and solidifies, and the door body 100 can be initially maintained in a predetermined shape. Then the carrying plate 211 drops, so that the door body 100 falls on the conveying device 10 and continues to be transported.

[0049] As a preferred solution of this embodiment, the centering assembly device 20 also includes a connecting frame 25 connecting multiple push rods 23, and the second driving member 24 is arranged between the connecting frame 25 and the supporting plate 211. The second driving member 24 can drive the connecting frame 25 to rise and fall relative to the supporting plate 211. The multiple push rods 23 can be raised and lowered under the drive of the connecting frame 25, and the supporting plate 211 can be provided with multiple openings for the push rods 23 to pass through.

[0050] In the above process, the frame 120 is bonded to the four sides of the insulating glass 110 to form the door body 100, and the door body 100 is in a front-facing position. In order to facilitate the use of fasteners to assemble the frame 120 and the corner code 130 on the back of the door body 100, the assembly line 200 of the refrigeration equipment door body also includes a flipping device 30. The flipping device 30 can drive the door body 100 to flip 180°, so that the door body 100 can switch between the front-facing and back-facing states.

[0051] Specifically, Figure 8-10 As shown, the flip device 30 includes a first bracket 31, a rotating shaft 32 rotatably connected to the first bracket 31, a driving component for driving the rotating shaft 32 to rotate, a flip frame 34 connected to the rotating shaft 32, a suction cup component 35 slidably connected to the flip frame 34 along the up-down direction, and a third driving member 36 for driving the suction cup component 35 to rise and fall. The suction cup component 35 is used to absorb the door body 100, and includes a connecting member 351 slidably connected to the flip frame 34 along the up-down direction, and a plurality of suction cups 352 connected to the connecting member 351. The plurality of suction cups 352 are located on one side of the axis of the rotating shaft 32 in the first direction, and are also located on one side of the axis of the rotating shaft 32 in the height direction (such as Fig.10 As shown), the plurality of suction cups 352 are turned over with the turning frame 34, and can have a third position (as shown) located below the top surface of the conveying device 10. Fig. 9 ), a fourth position (as shown) located above the conveying device 10 after flipping from the first position Fig.10 shown).

[0052] The multiple suction cups 352 are in the third position in the initial state. After the door body 100 is transported to the top of the multiple suction cups 352 by the conveying device 10, the third driving member 36 drives the multiple suction cups 352 to rise, and the suction cups 352 adsorb the door body 100. Then the flipping frame 34 flips and flips the multiple suction cups 352 to the fourth position. During this process, the door body 100 flips 180° following the suction cups 352. Then the third driving member 36 drives the door body 100 to descend, and the suction cups 352 release the door body 100. The door body 100 falls on the conveying device 10 and continues to be transported by the conveying device 10. It can be seen that the flipping device 30 not only flips the door body 100, but also makes the door body 100 move forward a certain distance.

[0053] The driving assembly includes a driving motor 331, a first sprocket connected to the output shaft of the driving motor 331, a second sprocket connected to the rotating shaft 32, and a transmission chain connected to the first sprocket and the second sprocket. The driving motor 331 drives the first sprocket to rotate, and the rotating shaft 32 is rotated through the transmission of the transmission chain and the second sprocket. The rotation of the rotating shaft 32 can drive the turning frame 34 to rotate, so that the suction cup assembly 35 can be turned over. At least two limit blocks 37 are arranged on the first bracket 31, and the at least two limit blocks 37 are respectively arranged on both sides of the first direction to limit the turning position of the turning frame 34.

[0054] In this embodiment, Fig. 9 As shown, the conveying device 10 includes at least two conveying sections 11 arranged along a first direction, and the flipping device 30 is disposed between two adjacent conveying sections 11. When the flipping device 30 drives the door body 100 to flip, the door body 100 is transferred from one conveying section 11 to another conveying section 11 at the same time. Fig.11 As shown, the conveying section 11 includes a second bracket 111 and two conveying lines 112 respectively located on both sides of the second bracket 111 in a second direction perpendicular to the first direction.

[0055] When the door body 100 is placed on the conveying section 11, its length direction is arranged along the second direction. In this case, both sides of the length of the door body 100 exceed the conveying section 11. Therefore, in conjunction with the reference Figure 5 As shown, the supporting plate 211 includes a first supporting plate 2111, two second supporting plates 2112 respectively located on both sides of the first supporting plate 2111 in the second direction, and gaps are formed between the first supporting plate 2111 and the two second supporting plates 2112 for the conveying line 112 to pass through, so that the supporting plate 211 can match the length of the door body 100, and will not interfere with the two conveying lines 112 during the lifting process.

[0056] Similarly, with reference Fig.12 As shown, the flip frame 34 includes a first flip frame 341, and two second flip frames 342 respectively located on both sides of the first flip frame 341 in the second direction. Gaps for the conveyor line 112 to pass through are formed between the first flip frame 341 and the two second flip frames 342. The first flip frame 341 and the two second flip frames 342 are both connected to a first suction cup assembly 35 and a third driving member 36. In this way, the flipping of the flip frame 34 will not interfere with the two conveyor lines 112, and the distribution of the positions of the flip frame 34 and the suction cup 352 also matches the length of the door body 100.

[0057] like Figure 6-7As shown in 13-14, the plurality of clamping blocks 212 include a first clamping block 2121 and a second clamping block 2122 respectively located on both sides of the first direction, a third clamping block 2123 and a fourth clamping block 2124 respectively located on both sides of the second direction, and the clamping space is formed by the first clamping block 2121, the second clamping block 2122, the third clamping block 2123 and the fourth clamping block 2124. The centering assembly device 20 also includes a fourth driving member 2125 for driving the first clamping block 2121 to move along the first direction, and a fifth driving member 2126 for driving the third clamping block 2123 to move along the second direction. The fourth driving member 2125 and the fifth driving member 2126 drive the first clamping block 2121 and the third clamping block 2123 to move respectively, so as to clamp and release the door body 100. The second clamping block 2122 and the fourth clamping block 2124 can be fixedly connected to the bearing plate 211.

[0058] Specifically, three first clamping blocks 2121 and two second clamping blocks 2122 are provided, so that a first clamping block 2121 and a second clamping block 2122 are provided on each of the first supporting plate 2111 and the two second supporting plates 2112. The centering assembly device 20 also includes a first sliding frame 26 slidably connected to the supporting plate 211 along the first direction, and a plurality of connecting rods 27 connecting the first sliding frame 26 and the plurality of first clamping blocks 2121. The fourth driving member 2125 is provided between the supporting plate 211 and the first sliding frame 26, and is used to drive the first sliding frame 26 to slide relative to the supporting plate 211 along the first direction, thereby driving the three first clamping blocks 2121 to move along the first direction. The first sliding frame 26 includes a connecting plate 261 and a connecting seat 262. The connecting plate 261 is located below the conveyor line 112. One side of the connecting seat 262 is connected to the connecting plate 261, and the other side is slidably connected to the supporting plate 211. A plurality of connecting rods 27 connect the connecting plate 261 and the first clamping block 2121. The connecting plate 261 and the conveyor line 112 are spaced apart in the height direction. In this way, the connecting plate 261 will not interfere with the conveyor line 112 during the process of rising and falling with the supporting plate 211.

[0059] The centering assembly device 20 also includes two adjustment plates 28 respectively arranged on both sides of the supporting plate 211 in the second direction. The two adjustment plates 28 can be adjusted in the second direction. The fifth driving member 2126 includes a main body connected to the first adjustment plate 28 and an output part telescopically arranged relative to the main body. The third clamping block 2123 is connected to the output part, and the fourth clamping block 2124 is connected to the other adjustment plate 28. In this way, the centering assembly device 20 can adapt to door bodies 100 of different lengths.

[0060] At least one first docking hole 281 is provided on the adjustment plate 28, and a plurality of second docking holes 2127 are provided on the supporting plate 211 along the second direction. The centering assembly device 20 also includes a latch member 29. When the latch member 29 connects the first docking hole 281 and different second docking holes 2127, the position of the adjustment plate 28 can be adjusted in the second direction.

[0061] Mate Reference Figures 3 to 19 As shown, the assembly line 200 also includes a lifting device 40, and at least two of the centering assembly devices 20 and the flipping devices 30 can be provided, and each centering assembly device 20 and the flipping device 30 plays a different role in the production process of the door body 100. Specifically, the centering assembly device 20 includes a first centering assembly device 210 and a second centering assembly device 220, and the flipping device 30 includes a first flipping device 310. The first centering assembly device 210, the first flipping device 310, the second centering assembly device 220, and the lifting device 40 are sequentially arranged along the conveying direction of the conveying device 10. The centering assembly device 20 and the flipping device 30 described in this paragraph are the first centering assembly device 210 and the first flipping device 310.

[0062] like Fig.15 As shown, the lifting device 40 includes a second lifting frame 41 and a sixth driving member 42 for driving the second lifting frame 41 to lift and lower. The second lifting frame 41 includes a lifting plate 411 located above it and a plurality of bearing blocks 412 arranged on the lifting plate 411 for bearing the door body 100. When the door body 100 moves to the lifting device 40, the lifting plate 411 rises, and the plurality of bearing blocks 412 lift the door body 100 from the conveying device 10. Then, a flexible belt can be manually wrapped around the door body 100 to prevent the door body 100 from deformation.

[0063] Similar to the carrying plate 211 in the centering assembly device 20, the lifting plate 411 includes a first lifting plate 4111 and two second lifting plates 4112 respectively located on both sides of the first lifting plate 4111 in the second direction, and gaps are formed between the first lifting plate 4111 and the two second lifting plates 4112 for the conveyor line 112 to pass through. In this way, the lifting plate 411 can match the length of the door body 100, and will not interfere with the two conveyor lines 112 during the lifting process.

[0064] In this embodiment, two first centering assembly devices 210 are provided, and the two first centering assembly devices 210 can work simultaneously to ensure that the process rhythm of assembling the door body 100 can be coordinated.

[0065] The present invention also provides a method for producing a refrigeration equipment door body 100, the method using the above-mentioned refrigeration equipment door body assembly line body 200 and comprising the following steps:

[0066] S1. Provide an insulating glass 110 and place the insulating glass 110 on a conveying device 10 for conveying. During conveying, a person may manually check the appearance of the insulating glass 110 to determine whether there are defects such as scratches on the surface of the insulating glass 110. When necessary, a person may also manually attach an advertising logo to the insulating glass 110.

[0067] S2. Provide multiple frames 120, install corner brackets 130 for connecting two adjacent frames 120 in some of the frames 120, and apply glue on the inner sides of multiple frames 120. The insulating glass 110 is rectangular, and the number of frames 120 is specifically four, and the number of corner brackets 130 is also four, so as to connect the frames 120 in pairs. However, at this time, the corner brackets 130 are not connected to the two frames 120 by fasteners, and the corner brackets 130 are only pre-inserted into the frames 120. When electrical components such as identification lights are provided on the door body 100, wires can also be pre-inserted into the frames 120. The frames 120 that have completed the above process can be placed on the insulating glass 110 and transported on the transport device 10 together with the insulating glass 110.

[0068] A semi-automatic glue applying device (not shown) may also be provided beside the assembly line 200. The operator may use the glue gun of the glue applying device to apply glue on the inner side of the frame 120. The glue dispensing speed and flow rate of the glue gun may be controlled by a control switch provided thereon. Since glue has a pungent odor and is a flammable item, the assembly line 200 further includes a dedicated glue applying room 50. The conveying device 10 is provided through the glue applying room 50. The glue applying room 50 is preferably made of transparent materials such as glass, and is provided with explosion-proof fire extinguishing supplies and temperature control supplies.

[0069] S3, the insulating glass 110 moves to the first centering assembly device 210, the carrying plate 211 rises, and the push rod 23 lifts the insulating glass 110 from the conveying device 10, and the lifted insulating glass 110 is located above the clamping block 212, which is convenient for the operator to bond the frame 120 around the insulating glass 110. The carrying plate 211 specifically rises to a position where its top surface is higher than the conveying device 10.

[0070] S4. Glue the frame 120 around the insulating glass 110 to form the door body 100, and then the top rod 23 descends to make the door body 100 fall on the supporting plate 211. After the door body 100 falls on the supporting plate 211, multiple clamping blocks 212 clamp the door body 100 around and maintain a preset time length so that the door body 100 can be shaped. The preset time here is preferably 10s-15s.

[0071] S5, the clamping block 212 is released, the carrying plate 211 descends, and the door body 100 falls on the conveying device 10 and is further conveyed by the conveying device 10. At this time, the first connecting hole 121 is set downward, that is, at this time, the front side of the door body 100 faces upward and the back side faces downward.

[0072] S6. The door body 100 moves to the first flipping device 310. The first flipping device 310 drives the door body 100 to flip 180 degrees so that the first connecting hole 121 is set upward, so as to facilitate the subsequent connection between the corner code 130 and the frame 120.

[0073] S7, use fasteners to connect the first connection hole 121 and the second connection hole 131, so that the multiple frames 120 are connected as a whole through the corner code 130.
