[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0050] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0051] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0052] In addition, the descriptions of "first", "second", etc. in the present invention are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0053] See Figures 1-13 As shown, the present invention provides a middle box assembly line for a vehicle air conditioning control panel, which is used to assemble structural components in a box body 90. The structural components include a light guide column 91, a slider 92, and a hinge 93. The middle box assembly line includes a circular conveyor line 1 and a loading station 2, a first pressing station 3, an oiling station 4, an assembly station 5, a marking station 6, and an unloading station 7 arranged in sequence on the conveying path of the circular conveyor line 1.

[0054] Among them, several carrier jigs 55 are placed at intervals on the circular conveyor line 1 to drive the several carrier jigs 55 to be transported along the conveying direction of the circular conveyor line 1; corresponding to each workstation, a jacking mechanism 66 is provided under the circular conveyor line 1, and each jacking mechanism 66 is used to perform jacking operations when the carrier jig 55 is transported to the corresponding workstation.

[0055] In the technical solution provided by this embodiment, the circular conveyor line 1, the plate carrier jig 55, and each workstation are all mounted on a frame 100. The circular conveyor line 1 includes two opposing conveyor belts, and the two sides of the plate carrier jig 55 are overlapped on the conveyor belts for transportation. A lifting mechanism 66 is installed between the two opposing conveyor belts, corresponding to each workstation position. In other embodiments, the conveyor belts can also be replaced with conveyor rollers.

[0056] In some embodiments, the middle box assembly line further includes a positioning and blocking mechanism (not shown in the drawings) configured in conjunction with the lifting mechanism 66. The positioning and blocking mechanism may be provided with a position sensor and a blocking block. The position sensor is used to detect whether the transported carrier jig 55 has reached the work station. When the carrier jig 55 reaches the work station, the blocking block blocks the continued transport of the carrier jig 55, and the lifting mechanism 66 further lifts the carrier jig 55. Furthermore, the working process and principle of the technical solution provided in this embodiment are as follows:

[0057] The carrier jig 55 is transported on the return conveyor line 1. When the carrier jig 55 is transported to the loading station 2, the corresponding lifting mechanism 66 lifts the carrier jig 55 off the return conveyor line 1. After the slider 92, hinge 93 and box body 90 are placed at the corresponding positions of the carrier jig 55 by manual or automated equipment, the carrier jig 55 returns to the return conveyor line 1. The conveyor line continues to carry the carrier jig 55 to the next station. Similarly, it is lifted by the lifting mechanism 66 set at each station and then operates. Based on the same principle, the corresponding steps in each station are completed, and finally the assembled middle box 99 is unloaded by the unloading mechanism.

[0058] In summary, the present invention adopts a circular conveyor line 1 to convey the carrier jig 55, and the carrier jig 55 can be transported in a circular manner, thereby reducing the loading and unloading equipment used for loading and unloading the carrier jig 55, reducing the complexity of operation, and saving costs; the loading station 2, the first pressing station 3, the oiling station 4, the assembly station 5, the marking station 6 and the unloading station 7 are arranged in sequence along the conveying direction of the circular conveyor line 1, and the jacking mechanism 66 arranged below the circular conveyor line 1 is cooperated, so that the corresponding process steps can be completed at each station based on the carrier jig 55, with high integration, reducing manual transportation costs and improving production efficiency.

[0059] See Figure 3 As shown, in some embodiments, the carrier jig 55 is provided with a plurality of placement positions, including a slider placement position 551, a hinge placement position 552 and a box body placement position 553, each placement position is designed as a contoured boss corresponding to the local contour of each structural member; wherein, a light guide column 91 is pre-installed in the slider 92.

[0060] The technical solution provided by this embodiment is that the slider placement position 551, the hinge placement position 552, and the box body placement position 553 can be arranged in a plurality of stepped layers in sequence. When placing the slider 92, the hinge 93, and the box body 90, the structural components are placed in a certain order. Furthermore, the placement position is designed in the form of a contoured boss to prevent the structural components from being placed incorrectly or upside down. In some cases, the slider 92 includes multiple sliders, and the multiple sliders can be divided into multiple groups and also placed in a plurality of stepped layers. For example, the present application requires six sliders to be assembled in the box body 90. The six sliders are divided into three groups and are placed on three slider placement positions 551 arranged in stepped layers. Among them, the first slider placement position corresponds to the placement of one slider, the second slider placement position corresponds to the placement of two sliders, and the third slider placement position corresponds to the placement of three sliders.

[0061] In some embodiments, a sensor may be provided corresponding to each placement position, and each sensor is used to detect whether a structural component is placed at each placement position.

[0062] In the technical solution of the present application, when the carrier jig 55 is transported to the loading station 2, the slider 92, hinge 93, and box body 90 and other structural components are loaded manually. Because the light guide 91 is inserted into the slider 92, the light guide 91 can be pre-installed and the slider 92 can be loaded directly at the loading station 2. In addition, due to the fluctuation of assembly time during manual operation, a corresponding control button can be provided to allow the operator to control the return and lowering of the lifting mechanism 66 in the loading station 2.

[0063] See Figure 4 As shown, in some embodiments, the jacking mechanism 66 includes a jacking fixed seat 661, a jacking platform 662 and a first driving member 663, wherein the jacking fixed seat 661 is provided with a movable guide rail 666 along the vertical direction, the jacking platform 662 is connected to a side plate 665, and the side plate 665 is connected to the movable guide rail 666 through a slider A664, and the first driving member 663 is connected to the jacking platform 662 for driving the jacking platform 662 to move back and forth along the movable guide rail 666.

[0064] The technical solution provided in this embodiment is that the lifting mechanism 66 can lift the carrier jig 55 from the return conveyor line 1 at the corresponding workstation without affecting the conveyance of other carrier jigs 55, that is, processing at one workstation does not affect processing at other workstations, thereby improving assembly production efficiency.

[0065] In this embodiment, movable guide rails 666 can be respectively set on the two opposite sides of the jacking fixed seat 661, and the jacking platform 662 is correspondingly provided with two opposite side panels 665. Each side panel 665 is respectively connected to the movable guide rails 666 on both sides to form a good support for the jacking platform 662.

[0066] In addition, a positioning hole is provided on the bottom surface of the carrier jig 55, and a positioning column 667 is provided on the upper surface of the jacking platform 662. The jacking platform 662 is used to support the carrier jig 55, and when contacting the carrier jig 55, the positioning column 667 is inserted into the positioning hole to improve the support stability.

[0067] See Figure 5 、 Figure 6 As shown, in some embodiments, the first pressing station 3 includes a first pressing mechanism 30, which is arranged above the circular conveyor line 1 and is used to move downward to press the slider 92, the hinge 93 and the box body 90, and press the light guide column 91 and the slider 92.

[0068] It is understandable that in some embodiments, in the loading station 2, the slider 92, the hinge 93 and the box body 90 can be loaded manually, but as the working time goes by, the working status of the loading operator will inevitably decline, which will cause the loading of various structural parts to be not placed in place. The technical solution provided in this embodiment is to set a first pressing mechanism 30 behind the loading station 2. The first pressing mechanism 30 can press and correct the slider 92, the light guide column 91, the hinge 93 and the box body 90, and can further press the slider 92 and the light guide column 91.

[0069] See Figure 5 、 Figure 6 As shown, in some embodiments, the first pressing mechanism 30 includes a movable plate 31, a guide post 32, a second driving member 33, and a pressing module 34. The guide post 32 is vertically arranged and passes through the movable plate 31. The second driving member 33 is connected to the movable plate 31 to drive the movable plate 31 to move back and forth along the guide post 32. The pressing module 34 is arranged on the side of the movable plate 31 facing the return conveyor line 1 and moves with the movable plate 31.

[0070] There may be a plurality of guide posts 32 . Preferably, there are four guide posts 32 , which are arranged at the four corners of the movable plate 31 . The movable plate 31 and the guide posts 32 are connected via sliding bearings.

[0071] In addition, a driving member mounting plate 341 is provided. The top ends of the four guide columns 32 support the driving member mounting plate 341. The driving member mounting plate 341 is arranged above the movable plate 31. The second driving member 33 is installed on the driving member mounting plate 341, and its output end is connected to the movable plate 31 to drive the movable plate 31 to move along the guide column 32.

[0072] See Figure 6As shown, in some embodiments, the pressing module 34 includes a mounting plate 341, a pressing block 342, and a connecting rod 343. The mounting plate 341 is connected to the movable plate 31 via a connecting column 344; a plurality of pressing blocks 342 are provided corresponding to the placement positions, and the pressing blocks 342 are provided on the side of the mounting plate 341 facing the circular conveyor line 1; a plurality of connecting rods 343 are provided corresponding to the pressing blocks 342, and each connecting rod 343 movably passes through the mounting plate 341, with one end connected to the pressing block 342 and the other end having a limiting ring around its circumference. An elastic member 345 is provided between the mounting plate 341 and the pressing block 342.

[0073] In this embodiment, the diameter of the retaining ring at the other end of the connecting rod 343 is larger than the diameter of the through-hole formed by the connecting plate through the mounting plate 341. This prevents the pressing block 342 and the connecting rod 343 from detaching from the mounting plate 341 under their own weight when the pressing block 342 is connected to one end of the connecting rod 343. Each pressing block 342 is provided with a corresponding connecting rod 343 connected to the mounting plate 341, and each pressing block 342 operates independently. An elastic member 345 is provided between the mounting plate 341 and the pressing block 342, providing a flexible pressure to prevent excessive pressure from damaging the underlying structural components.

[0074] The elastic member 345 may be a telescopic spring, which is mounted on the connecting rod 343 between the mounting plate 341 and the pressing block 342. A plurality of sensors 346 are provided on the other side of the mounting plate 341 away from the pressing block 342. Each sensor 346 is provided corresponding to each connecting rod 343 and is used to detect the pressing state of each pressing block 342.

[0075] See Figure 5 As shown, in some embodiments, the first pressing mechanism 30 further includes a limiting module 35 , which includes a first limiting structure 351 provided on the movable plate 31 , and a second limiting structure 352 provided opposite to the first limiting structure 351 .

[0076] The technical solution provided in this embodiment is to set a limit module 35 to limit the downward movement distance of the first pressing mechanism 30, which is intended to prevent the pressing module 34 from moving downward too far and damaging the underlying structural parts.

[0077] It is understood that the first limiting structure 351 is disposed on the movable plate 31, and the second limiting structure 352 is disposed relative to the first limiting structure 351. As the first limiting structure 351 moves and presses with the movable plate 31, the distance between the first limiting structure 351 and the second limiting structure 352 becomes increasingly closer. Therefore, the first limiting structure 351 and the second limiting structure 352 may be two opposing limiting blocks that, when the two limiting blocks touch, limit the pressing process of the pressing module 34. In some other embodiments, the first limiting structure 351 or the second limiting structure 352 may also be a distance sensor to control the pressing process of the first pressing mechanism 30 by measuring the distance between the first limiting structure and the second limiting structure 352.

[0078] See Figure 1 As shown, in some embodiments, the oiling station 4 includes a slider oiling mechanism 41 and a hinge oiling mechanism 42 arranged on one side of the circular conveyor line 1, so as to oil the slider 92 through the slider oiling mechanism 41 and oil the hinge 93 through the hinge oiling mechanism 42.

[0079] In the technical solution provided in this embodiment, the purpose of the oiling station 4 is to apply lubricating oil to the slider 92 and hinge 93 using an oiling mechanism to enhance lubrication during assembly. As will be appreciated, the slider 92 and hinge 93 are structurally distinct components, requiring different oiling locations. Using a single oiling mechanism would be difficult to address both components. For example, oiling the hinge 93 also includes lubricating the sides, while oiling the slider 92 only requires oiling the top portion. Therefore, to achieve the desired lubrication effect on these different components, separate slider oiling mechanisms 41 and hinge oiling mechanisms 42 are provided.

[0080] See Figure 7 As shown, in some embodiments, the slider oiling mechanism 41 includes a first three-axis moving module 411 and a slider oiling module 412, wherein the first three-axis moving module 411 is used to realize movement in the X-axis, Y-axis and Z-axis directions; the slider oiling module 412 is connected to the first three-axis moving module 411, and is used to move to the position to be oiled of the slider 92 for oiling operation.

[0081] The technical solution provided in this embodiment is understood to be a three-axis motion module composed of three linear modules: X, Y, and Z. The horizontal axis for left-right linear motion is the X-axis, the axis for front-back linear motion is the Y-axis, and the axis for up-and-down linear motion is the Z-axis, achieving a system operating in three-dimensional space. Typically, the Z-axis is used to mount operating components, such as the slider oiling module 412 in this embodiment. Driven by the three-axis motion module, the slider oiling module 412 can be moved above the slider 92, allowing precise oiling of the desired area.

[0082] The slider oiling module 412 comprises an oil barrel 4121 and an oiling nozzle 4123 connected to the barrel via a control valve. The oil barrel 4121 stores lubricating oil and contains a level sensor for detecting the remaining lubricating oil. This sensor monitors the lubricating oil level in real time and, when insufficient, alerts the operator to add lubricant via an alarm. Furthermore, the oiling nozzle 4123 is rotatable within a plane, specifically with a corresponding rotation mechanism. Typically, the oiling nozzle 4123 is tilted at a certain angle, allowing for lubrication of most structural components.

[0083] In addition, the slider oiling mechanism 41 further includes an image sensor, which is provided on the first three-axis moving module 411 and is used to detect whether the lubricating oil is applied in place.

[0084] It should be noted that when there are many sliders 92, more locations require lubricating oil. If lubricating all sliders 92 is performed on only one slider lubricating mechanism 41, it will take a long time, and this delay is likely to affect the normal progress of other processes. Therefore, in some preferred embodiments, multiple slider lubricating mechanisms 41 are provided. For example, two slider lubricating mechanisms 41 are provided. Based on the conveying direction of the circular conveyor line 1, the front slider lubricating mechanism is used to lubricate the sliders at the first and second slider placement positions, and the rear slider lubricating mechanism is used to lubricate the sliders at the third slider placement position.

[0085] See Figures 8-10 As shown, in some embodiments, the hinge oiling mechanism 42 includes: a rotating worktable 421, a second three-axis moving module 422, a hinge clamping module 423, and a hinge oiling module 424. The rotating worktable 421 is rotatably disposed on one side of the return conveyor line 1 and is used to place the hinge 93 thereon to drive the hinge 93 to rotate. The second three-axis moving module 422 is used to achieve movement in the X-axis, Y-axis, and Z-axis directions. The hinge clamping module 423 is connected to the second three-axis moving module 422 to transfer the hinge 93 to be oiled on the carrier jig 55 to the oiling worktable or to transfer the hinge 93 that has been oiled to the carrier jig 55 based on the second three-axis moving module 422. The hinge oiling module 424 is connected to the second three-axis moving module 422 and is used to oil the hinge 93 on the rotating worktable 421.

[0086] Compared to the slider oiling mechanism 41, the hinge oiling mechanism 42 provided in this embodiment requires transferring the hinge 93 from the carrier jig 55 to the rotating worktable 421. The rotating nature of the rotating worktable 421 is then used to drive the hinge 93 to rotate, exposing the side surface of the hinge 93 to be oiled to the hinge oiling module 424, completing the oiling process. Therefore, compared to the slider oiling mechanism 41, the hinge oiling mechanism 42 adds a hinge clamping module 423 for transporting the hinge 93 and a rotating worktable 421 for rotating the hinge 93. The second three-axis movable module 422 shares the same structural principles as the first three-axis movable module 411, and the hinge oiling module 424 shares the same structural principles as the slider oiling module 412, which will not be further described here. The slider oiling module 412 and the hinge clamping module 423 can be connected to the second three-axis movable module 422 via a connecting plate.

[0087] See Figure 9 As shown, in this embodiment, the rotating workbench 421 includes: two oppositely disposed vertical plates 4211, a placement panel 4212, and a third driving member 4213. The placement panel 4212 is rotatably mounted between the two oppositely disposed vertical plates 4211, and is used to place the transferred objects. Opposite shaft holes are formed on the two oppositely disposed vertical plates 4211, and rotation axes are provided on the two sides of the placement panel 4212, which are respectively inserted into the shaft holes. Furthermore, the output end of the third driving member 4213 is connected to the placement panel 4212, preferably to one of the rotation axes, to drive the placement panel 4212 to rotate between the two oppositely disposed vertical plates 4211.

[0088] In order to improve the stability of the hinge 93 after it is rotated on the placement panel 4212, a clamping block 4214 and a driving cylinder 4215 connected to the clamping block 4214 are also provided. The driving cylinder 4215 drives the clamping block 4214 to move to clamp and stabilize the hinge 93.

[0089] See Figure 10 As shown, in this embodiment, the hinge clamping module 423 includes: a first clamping member 4232, a second clamping member 4233, and a clamping cylinder 4231. The second clamping member 4233 is arranged opposite to the first clamping member 4232, and the output end of the clamping cylinder 4231 is connected to the first clamping member 4232 and / or the second clamping member 4233 to drive the first clamping member 4232 and the second clamping member 4233 to move toward or away from each other.

[0090] Therefore, the working process of the hinge oiling mechanism 42 in this embodiment is as follows: the clamping cylinder 4231 is actuated to open the first clamping member 4232 and the second clamping member 4233. Under the drive of the second three-axis moving module 422, the hinge clamping module 423 moves to the hinge 93 on the carrier jig 55. The clamping cylinder 4231 is actuated again, and the first clamping member 4232 and the second clamping member 4233 move toward each other to clamp the hinge 93. After that, the second three-axis moving module 422 is driven to open the hinge 93. The hinge clamping module 423 that clamps the hinge 93 is driven to move to the placement panel 4212 for placement. According to actual needs, the third driving member 4213 drives the placement panel 4212 to rotate, exposing different positions on the hinge 93 to be oiled. The hinge oiling module 424 performs the oiling work. After the oiling is completed, the hinge clamping module 423 clamps the hinge 93 again and, driven by the second three-axis moving module 422, places the oiled hinge 93 back on the carrier fixture 55.

[0091] In some embodiments, flexible members 4234 are provided on opposite sides of the first clamping member 4232 and the second clamping member 4233. The flexible members 4234 can be made of silicone, foam, etc. to protect the clamped member during clamping.

[0092] At this point, the oiling process of the slider 92 and the hinge 93 is completed. The slider 92 and the hinge 93 are further assembled in the box body 90.

[0093] In some embodiments, the middle box assembly line is provided with an assembly station 5, which is manually assembled. A slider 92 and a hinge 93 are provided in the box body 90 with corresponding placement positions and limit structures to form a good connection relationship.

[0094] A preferred assembly method is as follows: when assembling the various structural components, the operator picks up the box body 90 from the carrier jig 55, moves the box body 90 over the slider 92, and presses it downward to snap the slider 92 in. Then, the box body 90 with the slider 92 assembled is moved over the hinge 93 in the same manner and pressed downward to snap the hinge 93 in. A snap-fit ​​structure is configured between the hinge 93 and the box body 90. Finally, the assembled middle box 99 is positioned on the hinge 93 placement position 552. If there are multiple sliders 92, it is understandable that the multiple sliders 92 need to be snapped in order.

[0095] See Figure 11As shown, in some embodiments, the marking station 6 includes a marking device 61 and a transfer mechanism 62. The marking device 61 is provided on one side of the return conveyor line 1 and is used to mark the assembled middle boxes 99 that have completed the assembly work at the assembly station 5; the transfer mechanism 62 includes a third three-axis moving module 621, a transfer robot 622, and a transfer flip module 623. The transfer robot 622 is connected to the third three-axis moving module 621 and is used to transfer the middle boxes to be marked on the carrier jig 55 to the transfer flip module 623, or to transfer the marked middle boxes on the transfer flip module 623 to the carrier jig 55. The transfer flip module 623 is used to transfer the middle boxes to be marked or the marked middle boxes between the transfer robot 622 and the marking device 61.

[0096] In the technical solution provided in this embodiment, marking device 61 may be a laser marking device 61. Laser marking is a marking method that locally irradiates a structural component, vaporizing or changing the color of the surface material, thereby leaving a permanent mark. Laser marking can produce various text, symbols, and patterns by adjusting laser parameters. Character sizes can range from millimeters to microns. Marking can also record identification information such as the manufacturer, production date, and serial number, which is important for product traceability.

[0097] In this embodiment, after the middle box 99 is assembled, the middle box to be marked is transported along the circular conveyor line 1 to the marking station 6. The transfer mechanism 62 then transfers the middle box to the bottom of the marking mechanism for marking. The third three-axis moving module 621 has the same structure and operating principle as the first three-axis moving module 411, and the transfer robot 622 has the same structure and operating principle as the hinge clamping module 423, so these details will not be repeated here.

[0098] See Figure 12 As shown, in some embodiments, the transfer and flipping module 623 includes a transfer guide rail 6231, a flipping platform 6232, and a fourth drive member 6233. The transfer guide rail 6231 is provided corresponding to the transfer robot 622 and extends to the bottom of the marking device 61; the flipping platform 6232 is connected to the transfer guide rail 6231 via a guide block, and the flipping platform 6232 is connected to the flipping motor 6234 to drive the assembled middle box 99 to flip under the drive of the flipping motor 6234; the fourth drive member 6233 is connected to the guide block and is used to drive the guide block to move back and forth along the transfer guide rail 6231.

[0099] Specifically, the flipping platform 6232 is connected to the transfer guide rail 6231 through the sliding support seat 6235, and the working process of completing the marking of the middle box 99 is as follows: the flipping platform 6232 is first located on the side close to the circular conveyor line 1, and the transfer robot 622 clamps the assembled middle box and places it on the flipping platform 6232. The fourth driving member 6233 drives the flipping platform 6232 to move along the transfer guide rail 6231 until it is located below the marking device 61. Then the flipping motor 6234 drives the flipping platform 6232 to flip, exposing the position of the middle box 99 to be marked under the laser head of the marking device 61. The marking device 61 completes the marking operation and flips back. Driven by the fourth driving member 6233, the marked middle box returns to the side close to the circular conveyor line 1 along the transfer guide rail 6231, and the transfer robot 622 transfers the marked middle box 99 to the carrier fixture 55 and flows to the next process.

[0100] See Figure 11 As shown, in some embodiments, the middle box assembly line also includes a second pressing mechanism 63, which is arranged above the moving path of the flip platform 6232 and is used to press the slider 92 and the light guide column 91 after the slider 92 is installed into the light guide column 91 at the assembly station 5.

[0101] It is understandable that the light guide column 91 has different structures and shapes. If some of the light guide columns 91 are assembled at the loading station 2, it will affect the subsequent assembly. For example, if some of the light guide columns 91 are oblique light guide columns, they are bent in shape and take up a large space. During the assembly work, they will hinder the insertion of the slider 92. Therefore, the operator can insert the oblique light guide column after the slider 92 is inserted. The second pressing mechanism provided in this embodiment is arranged above the moving path of the flip platform 6232, and is intended to press the newly added light guide column 91 in the assembly station 5 with the slider 92 when the flip platform 6232 moves to the lower side. The structure and working principle of the second pressing mechanism are similar to those of the first pressing mechanism 30, and will not be repeated here.

[0102] See Figure 13 As shown, in some embodiments, the unloading station 7 includes an unloading mechanism 70, which includes a fourth three-axis moving module 710 and an unloading robot 720. The fourth three-axis moving module 710 is used to achieve movement in the X-axis, Y-axis, and Z-axis directions; the unloading robot 720 is connected to the fourth moving module to complete the unloading operation of the middle box 99 on the carrier fixture 55.

[0103] In the technical solution provided by this embodiment, the fourth three-axis mobile module 710 has the same structure and operating principle as the first three-axis mobile module 411, and the unloading robot 720 has the same structure and operating principle as the hinge clamping module 423, so they will not be repeated here. The middle box 99 moves along the return conveyor line 1 to the unloading station 7, where the corresponding lifting mechanism 66 lifts the carrier jig 55. Through the coordinated operation of the unloading robot 720 and the fourth three-axis mobile module 710, the unloading process of the middle box 99 is completed.

[0104] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. Any equivalent structural transformation made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields, is included in the scope of protection of the present invention.
