Description

Technical Field

[0001] The present invention belongs to the technical field of automobile air-conditioning assembly, and in particular relates to an assembly robot for upper and lower shells of new energy automobile air-conditioning. Background Art

[0002] During the assembly process of the automobile air conditioner, it is common to fix the lower housing on the workbench, and then press-fit and seal the upper housing and the lower housing by a press-fit mechanism; after the press-fitting is completed, the upper and lower housings need to be fixed with screws.

[0003] In the prior art, a Chinese patent with announcement number CN 117817318 A discloses an intelligent screw-driving device for an automobile air-conditioning assembly robot, which prevents the axis of the screw from being aligned with the axis of the screw hole during the process of tightening the upper and lower shells with the screw by setting an anti-skewing mechanism. However, in the above technology, the guide plate of the anti-skewing mechanism abuts against the tip of the screw. During the screw-in process, since the thickness of the tooth portion of the threaded portion of the screw is relatively small, in order to ensure the verticality of the screw, the guide plate needs to be tightly pressed against the threaded portion of the screw, which makes it easy to cause the tooth portion of the screw to deform during the screw-in process, thereby affecting the locking effect of the upper and lower shells of the air conditioner.

[0004] Therefore, it is necessary to propose an assembly robot for the upper and lower shells of new energy vehicle air conditioners to solve the above problems. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide an assembly robot for the upper and lower shells of new energy vehicle air conditioners, which is used to solve the problem in the prior art that the guide plate needs to be tightly pressed against the threaded portion of the screw, which makes it easy to cause the tooth portion of the screw to deform during the screw-in process, thereby affecting the locking effect of the upper and lower shells of the air conditioner.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] The present invention provides an assembly robot for the upper and lower shells of air conditioners of new energy vehicles, comprising a mechanical arm and a nail feeding assembly installed on the mechanical arm, wherein an anti-skewing assembly is fixedly installed at the output end of the nail feeding assembly, wherein the anti-skewing assembly comprises a base, wherein the axis of the base is provided with a through hole capable of allowing a screw to pass axially, wherein a plurality of slide grooves are axially arranged in the base with the axis of the base as the center, wherein a slider capable of sliding radially along the base is limitedly slidably installed in the slide groove, wherein a groove connected to the through hole is provided in the slide groove, wherein a clamping block capable of sliding axially along the base is slidably installed in the groove, and a positioning device matched with a tail of the screw is installed between the plurality of circumferentially arranged clamping blocks. The cam is provided with a protrusion which is fixed in the groove and is provided with a limit slide which cooperates with the protrusion. The limit slide is provided with a vertical section and an inclined section connected with the vertical section. The protrusion slides along the vertical section so that the supporting plate can support the bottom wall of the screw tail. The protrusion slides to the inclined section so that the supporting plate can be separated from the screw. A first spring is fixedly connected between the slider and the bottom wall of the slide groove.

[0008] Furthermore, the side wall of the slider away from the through hole is rotatably connected to a threaded rod, the threaded rod extends out of the base and is threadedly connected to the base, the end of the threaded rod extending out of the base is fixedly connected to a gear, and a gear ring is rotatably installed on the outer wall of the base, and the gear ring meshes with the gear.

[0009] Furthermore, a support plate connected to the clamp block is fixedly provided on the clamp block, the bottom wall of the positioning ring is provided on the support plate, the outer peripheral wall of the positioning ring is abutted against the side wall of the clamp block, and a sliding hole is provided on the support plate for the receiving plate to slide radially along the base.

[0010] Furthermore, a baffle is installed on the top wall of the clamping block, and the baffle can extend into the through hole. The baffle cooperates with the receiving plate to clamp the tail of the screw to limit the axial displacement of the screw.

[0011] Furthermore, the top wall of the clamp block is provided with an empty groove, and the baffle is radially slidably installed in the empty groove along the base. Sliding the baffle along the empty groove can make the baffle resist or break away from the positioning ring and the top wall of the screw.

The present application optimizes the anti-skewing assembly 3; the anti-skewing assembly 3 comprises a base 301, the axis of the base 301 is provided with a through hole that can allow the screw 4 to pass axially, and the base 301 is provided with a plurality of sliding grooves 302 circumferentially with the axis of the base 301 as the center, and a slider 303 that can slide radially along the base 301 is limitedly slidably installed in the sliding groove 302, a groove 304 connected to the through hole is provided in the slider 303, and a clamping block 305 that can slide axially along the base 301 is slidably installed in the groove 304, and a plurality of clamping blocks 305 arranged circumferentially are provided with the screw 4. The tail of the screw 4 is positioned in the positioning ring 5, and the receiving plate 306 can support the bottom wall of the tail of the screw 4. One end of the receiving plate 306 extends into the slide groove 302 and is fixedly connected with a protrusion 307. The inner wall of the slide groove 302 is provided with a limiting slide 308 that cooperates with the protrusion 307. The protrusion 307 is slidably connected to the limiting slide 308. Inside, the limiting slide 308 is provided with a vertical section 3081 and an inclined section 3082 connected to the vertical section 3081. The protrusion 307 is located in the vertical section 3081 so that the receiving plate 306 can support the bottom wall of the tail of the screw 4. The protrusion 307 slides to the inclined section 3082 so that the receiving plate 306 can be separated from the screw 4. A first spring 309 is fixedly connected between the slider 303 and the bottom wall of the slide groove 302, and the first spring 309 is used to support the slider 303.

[0023] In this scheme, first select the positioning ring 5 that matches the tail of the screw 4, then place the positioning ring 5 between multiple clamping blocks 305, slide multiple sliders 303 along the radial direction of the base 301, so that the clamping block 305 clamps the positioning ring 5, and then fix the anti-skew component 3 to the output end of the nail feeding component 2. After the nail feeding component 2 sends the screw 4 out, the screw 4 enters along the through hole until the tail of the screw 4 is supported on the receiving plate 306, and then the screw 4 is driven by the screw driving component to rotate into the screw hole of the upper and lower shells of the air conditioner to fix the upper and lower shells of the air conditioner; in this process, the positioning stability of the screw 4 is guaranteed by the positioning ring 5 and the receiving plate 306, and the axial sliding of the clamping block 305 is used to ensure the verticality of the screw 4 screwing-in process; wherein, by setting the positioning ring 5, it can adapt to different screws 4. For example, when the tail of the screw 4 is a polygon, a positioning ring 5 with an inner hole of the corresponding polygon is selected. During the screwing-in process of the screw 4, the screw 4 drives the fixing When the positioning ring 5 rotates and the tail of the screw 4 is circular, a positioning ring 5 with a corresponding circular inner hole is selected. During the screwing-in process of the screw 4, the screw 4 can rotate in the positioning ring 5. The positioning ring 5 is set to adapt to screws 4 with different tails; wherein, during the downward movement of the screw 4, the clamping block 305 is driven to slide downward, and the first spring 309 is compressed, and the receiving plate 306 is driven to move downward. At this time, the protrusion 307 slides downward along the vertical section 3081. When the protrusion 307 moves to the inclined section 3082, the screw 4 has been partially screwed into the screw hole of the upper and lower shells of the air conditioner. At this time, the screw 4 continues to rotate and move downward, and the protrusion 307 slides along the inclined section 3082, so that the receiving plate 306 is separated from the tail of the screw 4, so that the screw 4 can be completely screwed into the upper and lower shells of the air conditioner, avoiding secondary fixation of the screw 4; wherein, the first spring 309 is used to support the clamping block 305 on the one hand, and to ensure the verticality of the downward movement of the screw 4 on the other hand.

[0024] In one embodiment of the present invention, the side wall of the slider 303 away from the through hole is rotatably connected to a threaded rod 310, the threaded rod 310 extends out of the base 301 and is threadedly connected to the base 301, the end of the threaded rod 310 extending out of the base 301 is fixedly connected to a gear 311, and a gear ring 312 is rotatably installed on the outer wall of the base 301, and the gear ring 312 is meshed with the gear 311.

[0025] In this solution, rotating the gear ring 312 can cause multiple gears 311 to rotate synchronously, thereby driving the threaded rod 310 to rotate, thereby pushing the slider 303 to slide along the slide groove 302 so that the clamping block 305 clamps the positioning ring 5 for easy operation.

[0026] In one embodiment of the present invention, a support plate 313 connected to the clamp block 305 is fixedly provided on the clamp block 305, the bottom wall of the positioning ring 5 is provided on the support plate 313, the outer peripheral wall of the positioning ring 5 is abutted against the side wall of the clamp block 305, and the support plate 313 is provided with a sliding hole for the receiving plate 306 to slide radially along the base 301.

[0027] In this solution, the support plate 313 is used to axially support the positioning ring 5, and the receiving plate 306 is used to support the tail of the screw 4 to ensure the stability of the screw 4 during the screwing process.

[0028] In one embodiment of the present invention, a baffle 314 is installed on the top wall of the clamp block 305, and the baffle 314 cooperates with the receiving plate 306 to clamp the tail of the screw 4 to limit the axial displacement of the screw 4 and prevent the screw 4 from tilting.

[0029] In one embodiment of the present invention, a slot 315 is provided on the top wall of the clamp block 305, and the baffle plate 314 is radially slidably installed in the slot 315 along the base 1. Sliding the baffle plate 314 along the slot 315 can enable the baffle plate 314 to resist the top wall of the positioning ring 5 and the screw 4, or detach from the positioning ring 5 to facilitate the installation and removal of the positioning ring 5; and improve the clamping stability of the positioning ring 5.

[0030] In one embodiment of the present invention, a second spring 316 is fixedly connected between the baffle 314 and the inner wall of the slot 315 , so that the baffle 314 can cover the screw 4 under the elastic force of the second spring 316 .

[0031] In one embodiment of the present invention, the baffle 314 extends to the upper end of the screw 4 and is provided with an inclined edge 317. During the process of the screw 4 being fed in by the nail feeding assembly 2, the tail of the screw 4 can squeeze the inclined edge 317 to retract the baffle 314 to open the inner hole of the positioning ring 5. After the tail of the screw 4 can be completely moved to the inner hole of the positioning ring 5, the baffle 314 moves to above the top wall of the screw 4 under the action of the second spring 316, and after the screw 4 fixes the upper and lower shells of the air conditioner, the screw driving assembly is retracted, and at this time, the clamp 305 returns to its position under the action of the first spring 309.
