Description

Technical Field

[0001] The present invention relates to the technical field of automotive component processing, and particularly to an assembly method and an assembly production line for an air intake housing and an air conditioning box housing. Background Art

[0002] An automotive air conditioner is a device that realizes refrigeration, heating, ventilation, and air purification of the air inside the vehicle compartment. It can provide a comfortable riding environment for passengers, reduce the fatigue intensity of the driver, and improve driving safety. There are many components in an automotive air conditioner, and the assembly is also relatively complex. For example, when assembling the air intake housing onto the air conditioning box housing, it is necessary to fit the air intake housing onto the air conditioning box housing from top to bottom. As Figures 1-3 shown, a notched clamping groove 11 is provided on the air intake housing 1, and a sponge ring 21 is provided at the position corresponding to the clamping groove 11 on the air conditioning box housing 2. During assembly, it is necessary to fit the clamping groove 11 onto the sponge ring 11. However, during the fitting process, the end of the clamping groove at the notch will scratch the sponge ring 11, resulting in damage to the sponge ring 11. Therefore, how to avoid scratching the sponge ring 11 is an assembly difficulty that needs to be solved urgently. Summary of the Invention

[0003] To overcome the above drawbacks, an object of the present invention is to provide an assembly method and an assembly production line for an air intake housing and an air conditioning box housing, which can ensure the stability of the assembly and protect the sponge ring during the assembly process, reducing the risk of scratching the sponge ring.

[0004] One of the technical solutions adopted by the present invention to achieve the above object is: an assembly method for an air intake housing and an air conditioning box housing, including the following steps: fitting a profiling clamping member onto the sponge ring of the air conditioning box housing; clamping the sponge ring by the profiling clamping member to make the sponge ring in a radially contracted state; assembling the air intake housing onto the air conditioning box housing, and making the clamping groove of the air intake housing fit onto the profiling clamping member; and axially withdrawing the profiling clamping member from the clamping groove along the axis of the sponge ring to make the sponge ring radially rebound in the clamping groove.

[0005] First, fit the profiling clamping member onto the sponge ring, and use the profiling clamping member to wrap the outer wall of the sponge ring; then clamp the sponge ring by the profiling clamping member to make the sponge ring radially contract until the outer side of the profiling clamping member can match the inner wall of the clamping groove of the air intake housing; then assemble the air intake housing onto the air conditioning box housing, and make the clamping groove of the air intake housing fit onto the profiling clamping member, and then indirectly fit onto the sponge ring located inside the profiling clamping member; then axially withdraw the profiling clamping member from the clamping groove along the axis of the sponge ring. The sponge ring is no longer subjected to the clamping force of the profiling clamping member, and can thus radially rebound to abut against the inner wall of the clamping groove, realizing the assembly of the sponge ring and the clamping groove.

[0006] The beneficial effect of the assembly method of the present invention is as follows:

[0007] 1. When assembling the intake housing onto the air-conditioning box housing, since the card slot of the intake housing is sleeved onto the profiling clamping piece and does not directly contact the sponge ring, the card slot is prevented from scratching the sponge ring during the assembly process. At the same time, by utilizing the telescopic property of the sponge ring, the profiling clamping piece can radially compress the sponge ring, enabling the outer wall dimension of the profiling clamping piece to be tightened to match the inner wall of the card slot of the intake housing, thus avoiding the problem of increased assembly difficulty of the card slot caused by the thickness of the profiling clamping piece when adding the profiling clamping piece between the sponge ring and the card slot. When the profiling clamping piece withdraws from the card slot, the telescopic property of the sponge ring enables the sponge ring to automatically rebound, thereby realizing the assembly of the sponge ring and the card slot.

[0008] 2. The assembly of the card slot of the intake housing and the sponge ring of the air-conditioning box housing is carried out in two steps: The first step is when the entire intake housing is assembled onto the air-conditioning box housing, the card slot of the intake housing is simultaneously sleeved onto the profiling clamping piece, and at this time, the sponge ring has entered the card slot. The second step is to withdraw the profiling clamping piece from the card slot and utilize the rebound of the sponge ring to realize the assembly of the card slot and the sponge ring. In this assembly method, the final assembly of the card slot and the sponge ring is achieved by the radial rebound of the sponge ring. Therefore, this assembly method can effectively prevent the scratching of the sponge ring caused by directly sleeving the card slot on the sponge ring.

[0009] The second technical solution adopted by the present invention is: An assembly production line for an intake housing and an air-conditioning box housing, including:

[0010] A housing conveying line for conveying the air-conditioning box housing;

[0011] A rotary lifting mechanism arranged on the housing conveying line for moving the air-conditioning box housing on the housing conveying line to the assembly station;

[0012] A clamping mechanism located on one side of the housing conveying line for clamping the sponge ring of the air-conditioning box housing located at the assembly station;

[0013] A driving mechanism fixedly connected to the clamping mechanism for driving the clamping mechanism to move in a direction closer to or farther from the assembly station;

[0014] An assembly manipulator for assembling the intake housing onto the air-conditioning box housing located at the assembly station.

[0015] The beneficial effects of the assembly production line of the present invention are as follows:

[0016] Through the setting of the rotating and lifting mechanism, the air conditioner cabinet on the cabinet conveyor line can be switched to the assembly station; then, the driving mechanism drives the clamping mechanism to move towards the air conditioner cabinet and clamp the sponge ring of the air conditioner cabinet; then, the assembly manipulator operates to assemble the intake housing onto the air conditioner cabinet. Since the sponge ring is clamped within the clamping mechanism, the clamping groove of the intake housing can only be sleeved onto the clamping mechanism; finally, the driving mechanism drives the clamping mechanism to move away from the air conditioner cabinet so that the driving mechanism withdraws from the clamping groove of the intake housing, and the sponge ring and the clamping groove are assembled.

[0017] Through the cooperation of the clamping mechanism and the driving mechanism, not only the stable assembly of the clamping groove and the sponge ring is ensured, but also the sponge ring during the assembly process can be protected, reducing the risk of scratching the sponge ring.

[0018] Furthermore, a carrier plate capable of moving along the transmission direction is provided on the cabinet conveyor line, and the carrier plate is used to place the air conditioner cabinet.

[0019] Furthermore, the rotating and lifting mechanism includes a lifting substrate that can move up and down under the action of a lifting driving member, and a turntable that can rotate under the action of a rotating driving member is installed on the lifting substrate; when the lifting substrate moves upward, the turntable can support the carrier plate on the cabinet conveyor line and drive the carrier plate to move upward.

[0020] When the carrier plate with the air conditioner cabinet moves above the rotating and lifting mechanism, the lifting driving member drives the lifting substrate to move upward, and the turntable moves upward synchronously to support the carrier plate on the cabinet conveyor line. As the lifting substrate continues to move upward, the turntable can drive the carrier plate to move upward to disengage from the cabinet conveyor line; then, the rotating driving member drives the turntable to rotate, thereby driving the carrier plate and the air conditioner cabinet on the carrier plate to rotate so that the sponge ring of the air conditioner cabinet can face the clamping mechanism. Through the setting of the rotating and lifting mechanism, the switching of the carrier plate and the air conditioner cabinet on the carrier plate between the cabinet conveyor line and the assembly station can be achieved.

[0021] Furthermore, the lifting driving member includes a driving frame fixed on the cabinet conveyor line, and a pair of synchronous cylinders located on both sides of the lifting substrate are provided on the driving frame. The piston rod of each synchronous cylinder is fixedly connected to the lifting substrate through a connecting plate. Through the setting of the pair of synchronous cylinders, the stability of the movement of the lifting substrate can be improved.

[0022] Furthermore, a limiting portion for restricting the movement position of the lifting substrate is also installed on the driving frame. A plurality of limiting portions are provided and evenly distributed on the lifting substrate; each limiting portion includes a guiding rod and a guiding sleeve that are used in cooperation. The guiding rod is penetrated through the lifting substrate, its lower end is fixedly connected to the driving bracket, and a limiting block is provided at its upper end; the guiding sleeve is sleeved on the guiding rod and fixedly connected to the lifting substrate. In the limiting portion, the cooperation between the guiding rod and the guiding sleeve can guide the movement of the lifting substrate, further improving the movement stability of the lifting substrate. The setting of the limiting block can limit the highest point of the movement of the lifting substrate.

[0023] Furthermore, the lifting driving member further includes a buffer portion provided corresponding to each synchronous cylinder. The buffer portion includes a buffer rod and a buffer plate that are used in cooperation. The buffer plate is installed on the cylinder barrel of the corresponding synchronous cylinder; the buffer rod is movably penetrated through the driving frame, and an elastic buffer block facing the buffer plate is provided at its upper end; and the buffer rod is connected to the lifting substrate. When the synchronous cylinder drives the lifting substrate to move upward, the buffer rod moves upward accordingly, and the elastic buffer block moves toward the buffer plate until the elastic buffer block presses against the buffer plate. Through the setting of the buffer portion, when the lifting substrate moves upward to be close to the limiting block, the buffer plate can buffer the elastic buffer block, slowing down the moving speed of the elastic buffer block and the buffer rod, and further slowing down the moving speed of the lifting substrate toward the limiting block.

[0024] Furthermore, the rotary driving member includes a gear and a rack that are in meshing transmission. The gear is installed on the lifting substrate, and a turntable is fixedly connected thereto; the rack can move under the action of the linear transmission portion; the linear transmission portion includes a linear guide rail fixedly connected to the lifting substrate, a slide plate is slidably arranged on the linear guide rail, one side of the slide plate is fixedly connected to the rack, and the other side is connected to a linear cylinder installed on the lifting substrate. The linear transmission portion drives the rack to move linearly, thereby causing the gear meshing with the rack to rotate, so as to drive the turntable to rotate.

[0025] Furthermore, the clamping mechanism includes a pneumatic gripper. The pneumatic gripper is provided with a profiling clamping member that can open or close. When the profiling clamping member closes, a clamping groove that can press on the sponge ring is formed on the inner side of the profiling clamping member, and a profiling surface that matches the inner wall of the clamping groove of the air inlet housing is formed on the outer side.

[0026] Furthermore, the driving mechanism includes a driving substrate. An installation plate that can move in a direction close to or away from the air conditioner housing under the action of a driving cylinder is slidably arranged on the driving substrate. The installation plate is used to install the clamping mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following elaborates on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0044] Embodiment

[0045] An assembly method of an air intake housing and an air conditioner box housing according to the present invention includes the following steps: sleeving a profiling clamping member on a sponge ring 21 of the air conditioner box housing 2; clamping the sponge ring 21 by the profiling clamping member to make the sponge ring 21 in a radially contracted state; assembling the air intake housing 1 onto the air conditioner box housing 2, and sleeving a clamping groove 11 of the air intake housing 1 on the profiling clamping member; and axially withdrawing the profiling clamping member from the clamping groove 11 along the sponge ring 21 to make the sponge ring 21 radially rebound in the clamping groove 11.

[0046] First, sleeve the profiling clamping member on the sponge ring 21, and use the profiling clamping member to wrap the outer wall of the sponge ring 21; then clamp the sponge ring 21 by the profiling clamping member to make the sponge ring 21 radially contract until the outer wall of the profiling clamping member can match the inner wall of the clamping groove 11 of the air intake housing 1; then assemble the air intake housing 1 onto the air conditioner box housing 2, and sleeve the clamping groove 11 of the air intake housing 1 onto the profiling clamping member, and then indirectly sleeve it on the sponge ring 21 located inside the profiling clamping member; then axially withdraw the profiling clamping member from the clamping groove 11 along the sponge ring 21, and the sponge ring 21 is no longer subjected to the clamping force of the profiling clamping member, and thus can radially rebound to abut against the inner wall of the clamping groove 11 to realize the assembly of the sponge ring 21 and the clamping groove 11.

[0047] When the air intake housing is assembled onto the air conditioner box housing according to the assembly method of the present invention, since the clamping groove of the air intake housing is sleeved on the profiling clamping member and the clamping groove does not directly contact the sponge ring, the scraping of the sponge ring by the clamping groove during the assembly process is avoided; at the same time, by utilizing the elastic performance of the sponge ring, the profiling clamping member can radially compress the sponge ring so that the outer wall dimension of the profiling clamping member can be tightened to match the inner wall of the clamping groove of the air intake housing, avoiding the problem of increased assembly difficulty of the clamping groove caused by the thickness of the profiling clamping member when adding the profiling clamping member between the sponge ring and the clamping groove; when the profiling clamping member withdraws from the clamping groove, the elastic performance of the sponge ring is utilized to make the sponge ring automatically rebound, thereby realizing the assembly of the sponge ring and the clamping groove. In addition, the assembly of the clamping groove of the air intake housing and the sponge ring of the air conditioner box housing is carried out in two steps: the first step is that when the air intake housing is integrally assembled onto the air conditioner box housing, the clamping groove of the air intake housing is simultaneously sleeved on the profiling clamping member, and at this time, the sponge ring has entered the clamping groove; the second step is to withdraw the profiling clamping member from the clamping groove and utilize the rebound of the sponge ring to realize the assembly of the clamping groove and the sponge ring. In this assembly method, the final assembly of the clamping groove and the sponge ring is realized by the radial rebound of the sponge ring. Therefore, this assembly method can effectively avoid the scraping of the sponge ring caused by directly sleeving the clamping groove on the sponge ring.

[0048] It should be noted that when the profiling clamping member clamps the sponge ring, the outer wall contour of the profiling clamping member should not be larger than the outer wall contour of the sponge ring in its natural state, so as to ensure that the assembly difficulty of the card slot sleeved on the profiling clamping member is not greater than that of the card slot directly sleeved on the sponge ring.

[0049] In order to prevent the profiling clamping member from scratching the sponge ring when it exits the card slot, in some embodiments, the dimension of the profiling clamping member along the axial direction of the sponge ring should be greater than the axial dimension of the sponge ring. So that when the profiling clamping member is sleeved on the sponge ring, the profiling clamping member can completely wrap the outer wall of the sponge ring, and when the profiling clamping member clamps the sponge ring, the sponge ring can be integrally compressed in the axial direction.

[0050] Based on the above assembly method, an assembly production line for an intake housing and an air-conditioning box housing of the present invention is shown in the attached Figure 4 As shown, it includes a housing conveying line 3, a rotating lifting mechanism 4, a clamping mechanism 5, a driving mechanism 6 and an assembly manipulator (not shown in the figure). Among them, the housing conveying line 3 is used to convey the air-conditioning box housing 2, the rotating lifting mechanism 4 is arranged on the housing conveying line 3 and is used to move the air-conditioning box housing 2 on the housing conveying line 3 to the assembly station; the clamping mechanism 5 is located on one side of the housing conveying line 3 and is used to clamp the sponge ring 21 of the air-conditioning box housing 2 located at the assembly station; the driving mechanism 6 is fixedly connected to the clamping mechanism 5 and is used to drive the clamping mechanism 5 to move in a direction close to or away from the assembly station; the assembly manipulator is used to assemble the intake housing 1 onto the air-conditioning box housing 2 located at the assembly station.

[0051] Through the setting of the rotating lifting mechanism 4, the air-conditioning box housing 2 located on the housing conveying line 3 can be switched to the assembly station; then the driving mechanism 6 drives the clamping mechanism 5 to move towards the air-conditioning box housing 2 and clamps the sponge ring 21 of the air-conditioning box housing 2; then the assembly manipulator operates and assembles the intake housing 1 onto the air-conditioning box housing 2. Since the sponge ring 21 is clamped in the clamping mechanism 5, the card slot 11 of the intake housing 1 can only be sleeved on the clamping mechanism 5; finally, the driving mechanism 6 drives the clamping mechanism 5 to move away from the air-conditioning box housing 2, so that the clamping mechanism 5 exits the card slot 11 of the intake housing 1, and the sponge ring 21 and the card slot 11 are completed for assembly.

[0052] In some embodiments, as shown in the attached Figure 4 As shown, the housing conveying line 3 includes a conveying frame 31, and a carrier plate 32 that can move along its conveying direction is provided on the conveying frame 31. The carrier plate 32 is used to place the air-conditioning box housing 2 to be assembled, and a limiting member 33 for restricting the position of the air-conditioning box housing 2 is provided thereon.

[0053] See the attached Figures 5-6As shown in the figure, the rotary lifting mechanism 4 is located below the carrier plate 32. It includes a lifting base plate 41 that can move up and down under the action of a lifting driving member, and a turntable 42 that can rotate under the action of a rotation driving member is installed on the lifting base plate 41. When the lifting base plate 41 moves upward, the turntable 42 can support the carrier plate 32 on the housing conveyor line 3 and drive the carrier plate 32 to move upward, so that the carrier plate 32 is separated from the housing conveyor line 3.

[0054] Specifically, the lifting driving member includes a driving frame 43 fixedly connected to the conveyor frame 31. A pair of synchronous cylinders 44 located on both sides of the lifting base plate 41 are provided on the driving frame 43. The piston rod of each synchronous cylinder 44 is fixedly connected to the lifting base plate 41 through a connecting plate 45. When the pair of synchronous cylinders 44 are started simultaneously, the piston rods of the pair of synchronous cylinders 44 extend or retract simultaneously to drive the lifting base plate 41 to move up or down.

[0055] In some embodiments, a limiting portion for limiting the moving position of the lifting base plate 41 is further installed on the driving frame 43. A plurality of limiting portions are provided and are evenly distributed on the lifting base plate 41. Each limiting portion includes a guiding rod 451 and a guiding sleeve 452 that are used in cooperation. Among them, the guiding rod 451 penetrates through the lifting base plate 41, its lower end is fixedly connected to the driving bracket 43, and a limiting block 453 is provided at its upper end. The guiding sleeve 452 is sleeved on the guiding rod 451 and is fixedly connected to the lifting base plate 41. In the limiting portion, the movement of the lifting base plate 41 can be guided through the cooperation of the guiding rod 451 and the guiding sleeve 452, further improving the movement stability of the lifting base plate 41. The highest point of the movement of the lifting base plate 41 can be limited through the setting of the limiting block 453.

[0056] It should be noted that when the carrier plate 32 is located on the housing conveyor line 3, there is a gap between the upper end of the guiding rod 451 and the lower end of the carrier plate 32, and there is also a gap between the turntable 42 and the carrier plate 32 when the lifting base plate 41 is at the lowest point of movement, so as to prevent the rotary lifting mechanism 4 from touching the carrier plate 32 during the transmission of the carrier plate 32 along the housing conveyor line 3.

[0057] During the upward movement of the lifting base plate 41, if the moving speed of the lifting base plate 41 is too high, resulting in too large a movement inertia when the lifting base plate 41 abuts against the limiting block 453, there is a risk that the limiting block 453 will break away from the guiding rod 451. Therefore, refer to the appendix Figure 7As shown, in some embodiments, a buffer portion may be added to reduce the risk of the limit block 453 disengaging from the guide rod 451. Specifically, the buffer portions are provided in one-to-one correspondence with the synchronous cylinders 44, and each buffer portion includes a buffer rod 461 and a buffer plate 462 that are used in cooperation. The buffer plate 462 is fixedly installed on the cylinder barrel of the corresponding synchronous cylinder 44. The buffer rod 461 is movably inserted through the driving frame 43, and an elastic buffer block 463 facing the buffer plate 462 is provided at the upper end thereof. The buffer rod 461 is fixedly connected to the jacking substrate 41 through a support plate 47. During the upward movement of the jacking substrate 41, when the elastic buffer block 463 contacts the buffer plate 462, there is still a gap between the jacking substrate 41 and the limit block 453. By providing the buffer portion, when the jacking substrate 41 moves upward to be close to the limit block 453, the buffer plate 462 can buffer the elastic buffer block 463, slow down the moving speed of the elastic buffer block 463 and the buffer rod 461, and further slow down the moving speed of the jacking substrate 41 in the direction of the limit block 453.

[0058] In some embodiments, referring to the attached Figure 6 As shown, the rotation driving member includes a gear 481 and a rack 482 that are in meshing transmission. Among them, the gear 481 is installed on the jacking substrate 41, and a turntable 42 is fixedly connected thereto. The rack 482 can perform linear movement under the action of the linear transmission portion and mesh with the gear 481 for transmission. Specifically, the linear transmission portion includes a linear guide rail 483 fixedly connected to the jacking substrate 41. A sliding plate 484 is slidably provided on the linear guide rail 483. One side of the sliding plate 484 is fixedly connected to the rack 482, and the other side is connected to a linear cylinder 485 installed on the jacking substrate 41. When the linear cylinder 485 is activated, the sliding plate 484 slides along the linear guide rail 483, thereby driving the rack 482 to move. Due to the meshing of the rack 482 and the gear 481, the gear 481 rotates accordingly and drives the turntable 42 to rotate.

[0059] In some embodiments, the driving frame 43 includes a U-shaped frame. The two ends of the U-shaped frame are bent outward to form folding plates for connecting the conveying machine frame 31. A receiving space for receiving the jacking substrate 41 is defined inside the U-shaped frame.

[0060] When the carrier plate 32 with the air conditioner casing 2 placed thereon moves along the casing conveying line 3 to the upper side of the rotary lifting mechanism 4, a pair of synchronous cylinders 44 are started simultaneously. The lifting base plate 41 moves upward accordingly, the guide sleeve 452 moves upward along the guide rod 451 accordingly, the buffer rod 461 moves toward the buffer plate 462 accordingly, and the rotary driving member and the turntable 42 move upward to the turntable 42 supporting the carrier plate 32. When the lifting base plate 41 continues to move upward, the turntable 42 drives the carrier plate 32 to move upward until the elastic buffer block 463 abuts against the buffer plate 462. At this time, there is a gap between the lifting base plate 41 and the limit block 453. As the lifting base plate 41 continues to move upward, the elastic buffer block 463 deforms and presses against the buffer plate 462, and the moving speed of the lifting base plate 41 slows down accordingly until the lifting base plate 41 abuts against the limit block 453. At this time, the carrier plate 32 and the air conditioner casing 2 on the carrier plate 32 move to the highest point. Then the linear cylinder 485 is started, the slide plate 484 slides along the rail 483 accordingly and drives the rack 482 to move, the gear 481 rotates accordingly and drives the turntable 42 to rotate, and the carrier plate 32 and the air conditioner casing 2 on the turntable 42 rotate accordingly until the sponge ring 21 of the air conditioner casing 2 faces the clamping mechanism 5. At this time, the sponge ring 21 moves to the position to be assembled. Through the setting of the rotary lifting mechanism 4, the switching between the carrier plate 32 and the air conditioner casing 2 on the carrier plate 32 between the casing conveying line 3 and the assembly station can be realized.

[0061] In some embodiments, referring to the attached Figure 8 shown, the driving mechanism 6 includes a driving base plate 61 fixedly connected to one side of the conveying machine frame 31. A mounting plate 63 that can move in the direction approaching or departing from the air conditioner casing 2 under the action of a driving cylinder 62 is slidably arranged on the driving base plate 61, and a clamping mechanism 5 is mounted on the mounting plate 63.

[0062] In some embodiments, referring to the attached Figures 8-9 shown, the clamping mechanism 5 includes a pneumatic gripper 51. A pair of clamping arms 52 that can move toward or away from each other are arranged on the pneumatic gripper 51. A first clamping plate 53 and a second clamping plate 54 are respectively mounted on the pair of clamping arms 52, and the first clamping plate 53 and the second clamping plate 54 jointly form a profiling clamping member that can be opened or closed under the action of the pneumatic gripper 51. When the pair of clamping arms 52 move toward each other, the first clamping plate 53 and the second clamping plate 54 are closed to each other so that the inner sides of the first clamping plate 53 and the second clamping plate 54 jointly form a clamping groove that can press on the sponge ring 21, and the outer sides of the first clamping plate 53 and the second clamping plate 54 can jointly form a profiling surface that matches the inner wall of the clamping groove 11 of the intake housing 1.

[0063] In the initial state, the profiling gripper is in an open state. The driving cylinder 62 is activated to drive the mounting plate 63 to move the clamping mechanism 5 towards the air-conditioning box housing 2. The first clamping plate 53 and the second clamping plate 54 can be jointly sleeved on the sponge ring 21. At this time, there are gaps between the inner sides of the first clamping plate 53 and the second clamping plate 54 and the outer wall of the sponge ring 21. The pneumatic gripper 51 is activated, and a pair of clamping arms 52 move towards each other. The first clamping plate 53 and the second clamping plate 54 simultaneously clamp the outer wall of the sponge ring 21 and compress the sponge ring 21 until the outer sides of the first clamping plate 53 and the second clamping plate 54 can jointly form a profiling surface matching the inner wall of the clamping groove 11 of the air intake housing 1. Then, an assembly manipulator (not shown in the figure) assembles the air intake housing 1 onto the air-conditioning box housing 2 and makes the clamping groove 11 of the air intake housing 1 sleeved on the outer sides of the first clamping plate 53 and the second clamping plate 54. Then, the driving cylinder 62 is activated again to drive the mounting plate 63 to move the clamping mechanism 5 away from the air-conditioning box housing 2. The first clamping plate 53 and the second clamping plate 54 then withdraw from the clamping groove 11, and the assembly of the air intake housing 1 and the air-conditioning box housing 2 is completed. Finally, the assembled air-conditioning box housing 2 is moved to the housing conveying line 3 again through the rotary lifting mechanism 4.

[0064] It should be noted that the assembly manipulator is a prior art and will not be elaborated in this embodiment.

The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it. It cannot be used to limit the protection scope of the present invention.
