Description

Technical Field

[0001] This invention relates to the field of automotive air conditioning manufacturing technology, specifically, to an automotive air conditioning pipe pressing device. Background Technology

[0002] As a core component of the air conditioning system, automotive air conditioning piping is like the "blood vessels of the human body," undertaking the vital functions of connecting various key components and transporting refrigerant. The processing quality of its ports directly determines the sealing performance and operational reliability of the air conditioning system, thus affecting driving comfort and overall vehicle quality. With the automotive industry moving towards lightweighting and high performance, the market is placing higher demands on the processing precision, finished product qualification rate, and production efficiency of air conditioning piping. In particular, the need for standardization and stability in plastic forming processes such as upsetting and radial extrusion of pipe ports is becoming increasingly urgent.

[0003] Currently, traditional automotive air conditioning pipe port processing suffers from fragmented processes and low automation, involving numerous manual interventions. This leads to defects such as pipe tilting, unevenness, and burr residue, causing problems like insufficient coaxiality, eccentricity, and cracking in subsequent upsetting and radial extrusion processes. These issues severely impact sealing performance and increase the risk of refrigerant leakage. Furthermore, traditional processing methods lack effective online inspection tools, making it difficult to detect defective products in real time after processing. This necessitates additional manual re-inspection, increasing labor costs and reducing production efficiency, making it difficult to meet the demands of large-scale production.

[0004] To address the aforementioned technical challenges, automate, standardize, and refine the processing flow, improve processing quality and production efficiency, and reduce errors caused by manual intervention, it is imperative to develop a specialized pipe-pressing device that integrates feeding, processing, unloading, and quality inspection. By optimizing the processing flow, adding a precise transfer mechanism and an online inspection unit, the device can ensure stable and controllable processing quality at the pipe ends, meeting the large-scale, high-precision processing requirements of automotive air conditioning pipes. Summary of the Invention

[0009] To better realize the present invention, the feeding unit further includes a right limiting plate and a left limiting plate. The left limiting plate and the right limiting plate are both vertically arranged to form a feeding channel. One end of the feeding channel is connected to the feeding roller and is provided with a spacing greater than the diameter of the processing tube. Along the axial direction of the processing tube, the left limiting plate is shorter than the right limiting plate.

[0010] To better realize the present invention, the visual inspection unit further includes a visual inspection component and an inspection bracket. The visual inspection component is mounted on the inspection bracket, and the inspection bracket is mounted on the left limiting plate. The optical axis of the visual inspection component is perpendicular to the unloading channel. The image acquisition area of ​​the visual inspection component coincides with the area of ​​the right limiting plate and the area of ​​the left limiting plate.

[0011] To better realize the present invention, the unloading unit further includes a cylinder and a support slide plate. The cylinder is mounted on the unloading base, and the support slide plate is slidably connected to the right limit plate. The output end of the cylinder is connected to the support slide plate, and the support slide plate is used to carry the processing tube and make it roll.

[0012] To better realize the present invention, the temporary storage box further includes a temporary storage box body, an adjusting plate, a lead screw, and an adjusting motor. The temporary storage box body is installed on the feeding base. The adjusting plate is rotatably connected to the rotating shaft and slides in the temporary storage box body. The adjusting motor is installed on the adjusting plate. The lead screw is installed at the output end of the adjusting motor. The lead screw is threadedly connected to the bracket on the temporary storage box body.

[0013] To better realize the present invention, a guide limiting plate is further installed on the adjusting plate, and the guide limiting plate is vertically arranged.

[0014] To better realize the present invention, the conveying module further includes springs, which are distributed on both sides of the feed roller, with one side spring abutting against the adjusting plate and the other side spring abutting against the end of the rotating shaft.

[0015] To better realize the present invention, the feeding device further includes a movable base, a support chaff, a feeding assembly, and a storage hopper. The feeding assembly includes a conveyor frame, a conveyor belt, and a conveyor roller. One end of the conveyor frame is mounted on the movable base, and the other end is mounted on the support chaff. The support chaff is mounted on the movable base. The conveyor roller is rotatably connected to the conveyor frame. The conveyor belt is sleeved on the conveyor roller, and a material-pulling plate is provided on the conveyor belt.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: (1) This invention forms a continuous automated processing flow by setting up a feeding device, a processing device and a unloading device. It uses a three-axis transfer claw to realize the orderly flow of pipe fittings between the end flattening unit, the end upsetting unit, the radial extrusion unit and the end deburring unit. First, the pipe end is flattened to effectively avoid pipe end tilting, unevenness and initial burr problems, and ensure the coaxiality of the subsequent upsetting and radial extrusion processing to prevent pipe fitting eccentricity and cracking defects. Then, the pipe end upsetting, multi-ring sealing rib radial extrusion forming and deburring are completed in sequence. The forming accuracy of the pipe end is high, the structural sealing and the overall finished product quality are greatly improved. At the same time, a vision inspection unit is integrated in the unloading device, which can detect the pressing and processing quality of the pipe fittings in real time during the unloading process, automatically identify unqualified pipe fittings and remind manual removal, realize the integrated operation from feeding, multi-process pipe end plastic forming and trimming to online quality inspection and automatic unloading. The degree of automation is high, the process connection is compact, effectively reduce the labor intensity of manual labor, and improve production efficiency and product yield. (2) In this invention, the feeding unit, through the cooperation of a temporary storage box, a feeding roller with a single tube receiving groove and a driving mechanism, realizes the orderly and quantitative feeding of air conditioning pipes one by one, and the feeding cycle is stable and reliable; the left and right limit plates form a feeding channel, which not only constrains the falling trajectory of the pipes, but also uses the height difference to expose the processing area of ​​the pipe end, providing an unobstructed field of view for visual inspection. The visual inspection unit can collect the forming images of the pipe upsetting ribs and annular sealing ribs in real time, intelligently identify defects and alarm for unqualified parts, suspend feeding, and resume operation after manual removal and reset; at the same time, the cylinder drives the support slide plate to support and drive the pipe to rotate, realizing 360° all-round inspection of the processing part without dead angles, which greatly improves the quality inspection accuracy. The support slide plate is equipped with silicone rubber pads, which can increase the friction to drive the pipe to rotate, and protect the surface of the pipe from bumps and scratches. The whole system integrates automatic feeding, pipe rotation, online full inspection, and defective product warning and shutdown functions into one, with a compact structure, strong linkage, reduced manual intervention, and effectively improved production efficiency and pipe forming yield. (3) In this invention, the temporary storage box forms an adjustable spacing structure through the temporary storage box body, adjusting plate, lead screw and adjusting motor, which can be adapted to processing tubes of different lengths. The motor drives the lead screw to drive the adjusting plate to slide, accurately adjusting the internal accommodating spacing, so that the processing end of the tube is always in close contact and positioned, ensuring that the processing area is accurately within the visual inspection and shooting range when the tube falls into the unloading channel; the added guide limiting plate can limit the tube axially, avoiding axial offset and misalignment, further ensuring the accuracy of the detection position. At the same time, symmetrical springs are set on both sides of the unloading roller, which automatically squeeze and compensate as the position of the adjusting plate changes, driving the unloading roller to adaptively slide on the rotating shaft and keep it centered, so that the support force of tubes of different lengths is balanced and the placement is stable, effectively preventing the tubes from tilting or tipping over. It is compatible with unloading of tubes of multiple specifications, with strong self-adaptation and high positioning accuracy, providing a reliable guarantee for subsequent stable rotation and accurate visual inspection.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Example 1:

[0027] This embodiment provides a crimping device for automotive air conditioning pipes, specifically as follows: Figure 1 As shown, it includes: The feeding device 10 is used to transport the processing tubes 40 one by one to the processing device 20 for processing; Processing device 20 is used to perform plastic forming processing on the end of processing tube 40; The unloading device 30 performs the unloading operation on the processed tube 40 after processing; The processing device 20 includes a port leveling unit 201, a port upsetting unit 202, a radial extrusion unit 203, a port deburring unit 204, and a three-axis transfer claw 205 mounted on a frame. The three-axis transfer claw 205 is used to grip the processing tube 40 and transfer it. All components included in the processing device 20 are existing technologies and will not be described in detail. The feeding device 30 includes a feeding unit and a vision inspection unit; the feeding unit is used to output the processing tubes 40 one by one, and the vision inspection unit is set on the output path of the processing tubes 40 to detect the processing quality of the processing position of the processing tubes 40.

[0028] When processing the end of the processing tube 40, the processing tubes 40 to be processed are first placed in batches into the feeding device 10. The feeding device 10 then transports the processing tubes 40 one by one to the processing device 20. The three-axis transfer claw 205 clamps the processing tubes 40 and transfers them to the end leveling unit 201 for end leveling. This avoids tilting, unevenness, burrs, etc., at the end of the processing tube 40. This setting ensures high coaxiality, no eccentricity, and no cracking during subsequent upsetting and radial extrusion. After the leveling is completed, the three-axis transfer claw 205 clamps the processing tube 40 and transfers it to the end upsetting unit 202, where the processing tube 40 undergoes upsetting. Afterward, the three-axis transfer claw 205... 5. The processed tube 40 is clamped and transferred to the radial extrusion unit 203, where the processed tube 40 undergoes radial extrusion to form multiple ring-shaped sealing ribs. Then, the three-axis transfer claw 205 clamps and transfers the processed tube 40 to the port deburring unit 204, where the processed tube 40 undergoes trimming to remove burrs that may have been generated during the previous processing, thereby improving the quality of the finished product. Subsequently, the three-axis transfer claw 205 clamps the processed tube 40 and puts it into the unloading unit of the unloading device 30, where the unloading unit completes the unloading. During the unloading process, the vision inspection unit detects the processing position of the processed tube 40, identifies unqualified processed tubes 40, and reminds the operator to remove them manually.

[0029] Example 2:

[0030] This embodiment further extends the above embodiment, specifically as follows: Figures 2-5 As shown, the unloading unit includes an unloading base 301, a temporary storage box, a conveying module, and a collection box 307. The temporary storage box and the collection box 307 are installed on the unloading base 301. The conveying module includes an unloading roller 305 and a drive source for rotating the unloading roller 305. A support plate 304 is installed on the unloading device 30. The unloading roller 305 is rotatably connected to the support plate 304. The unloading roller 305 is provided with multiple receiving slots 313. The unloading roller 305 is located at the bottom of the temporary storage box and communicates with it. Each receiving slot 313 can and can only accommodate one processing tube 40.

[0031] Specifically, the three-axis transfer claw 205 puts the processing tube 40 into the temporary storage box. The processing tube 40 falls to the bottom of the temporary storage box. When the feed roller 305 rotates to the receiving groove 313 and is in the temporary storage box, the processing tube 40 automatically falls into the receiving groove 313. As the three-axis transfer claw 205 rotates, the adjusting plate 303 brings out the corresponding processing tube 40 and realizes the unloading of the processing tube 40. The processing tube 40 will fall into the collection box 307 and be collected. The vision inspection unit also performs the inspection operation during the period when the processing tube 40 falls from the receiving groove 313 into the collection box 307.

[0032] Furthermore, the drive source includes a rotating shaft 316, a drive motor 317, and a transmission belt 319. The drive motor 317 is mounted on the unloading base 301, and the transmission belt 319 is sleeved on the output end of the drive motor 317 and the rotating shaft 316. The unloading roller 305 is mounted on the rotating shaft 316. The drive motor 317 drives the transmission belt 319, which in turn drives the rotating shaft 316, which in turn drives the unloading roller 305 to rotate.

[0033] Furthermore, the feeding unit also includes a right limiting plate 308 and a left limiting plate 312. The left limiting plate 312 and the right limiting plate 308 are both vertically arranged and form a feeding channel. One end of the feeding channel is connected to the feeding roller 305 and is provided with a spacing larger than the diameter of the processing tube 40. Along the axial direction of the processing tube 40, the left limiting plate 312 is shorter than the right limiting plate 308.

[0034] The feeding channel can limit the falling trajectory of the processing tube 40, while the left limiting plate 312 is shorter than the right limiting plate 308 in order to expose the processing position at the end of the processing tube 40, so as to facilitate the visual inspection unit to collect image information.

[0035] Furthermore, the visual inspection unit includes a visual inspection component 309 and an inspection bracket 320. The visual inspection component 309 is mounted on the inspection bracket 320, and the inspection bracket 320 is mounted on the left limiting plate 312. The optical axis of the visual inspection component 309 is perpendicular to the unloading channel. The image acquisition area of ​​the visual inspection component 309 coincides with the area of ​​the right limiting plate 308 and the left limiting plate 312.

[0036] During operation, the vision inspection component 309 will point to the area where the right limit plate 308 overlaps with the left limit plate 312. When the processing tube 40 falls from the feeding channel, the vision inspection component 309 will acquire the processing position image of the processing tube 40 and transmit the image information to the processing terminal for identification. If it is unqualified, an alarm will be triggered to prompt the staff to remove it, and the drive motor 317 will stop rotating to prevent further feeding. After the staff removes the unqualified processing tube 40 and presses the reset button, the above process continues.

[0037] Furthermore, the unloading unit also includes a cylinder 306 and a support slide plate 310. The cylinder 306 is mounted on the unloading base 301, and the support slide plate 310 is slidably connected to the right limit plate 308. The output end of the cylinder 306 is connected to the support slide plate 310, and the support slide plate 310 is used to carry the processing tube 40 and make it roll.

[0038] Initially, cylinder 306 is extended. When the processing tube 40 passes through the feeding channel, it is blocked by the support slide 310. A silicone rubber pad is provided on the contact surface between the support slide 310 and the processing tube 40 to increase friction. Then, cylinder 306 retracts, and the support slide 310 moves synchronously. At this time, the support slide 310 drives the processing tube 40 to rotate, while the vision inspection component 309 performs a 360° inspection of the processing position of the processing tube 40 to improve the inspection effect. The process continues until the support slide 310 no longer supports the processing tube 40, at which point the processing tube 40 falls into the collection box 307. Then, cylinder 306 extends, causing the support slide 310 to reset, and the feeding roller 305 delivers another processing tube 40 to the feeding channel, and the cycle repeats.

[0039] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0040] Example 3:

[0041] This embodiment further extends the above embodiment, specifically as follows: Figure 2 , Figure 4 , Figure 5 As shown, the temporary storage box includes a temporary storage box body 302, an adjusting plate 303, a lead screw 314, and an adjusting motor 315. The temporary storage box body 302 is mounted on the unloading base 301. The temporary storage box body 302 is tilted at the top to facilitate the three-axis transfer claw 205 to place the processing tube 40 into the temporary storage box, and the bottom is vertical to facilitate the limitation of the position of the processing tube 40. The adjusting plate 303 is rotatably connected to the rotating shaft 316 and slides in the temporary storage box body 302. The adjusting motor 315 is mounted on the adjusting plate 303, and the lead screw 314 is mounted on the output end of the adjusting motor 315. The lead screw 314 is threadedly connected to the bracket on the temporary storage box body 302.

[0042] Since the processing tubes 40 have different lengths, the adjusting motor 315 drives the lead screw 314 to rotate. Under the action of the threaded connection, the adjusting motor 315 drives the adjusting plate 303 to slide on the temporary storage box 302, thereby adjusting the distance between the adjusting plate 303 and the opposite surface of the temporary storage box 302. This ensures that the processing end of the processing tube 40 is always in contact with the opposite surface of the temporary storage box 302 and the adjusting plate 303. This ensures that when the processing tube 40 falls into the unloading channel, the processing end is exactly in the area where the right limit plate 308 is longer than the left limit plate 312, ensuring that the processing position can be identified by the vision inspection component 309.

[0043] Furthermore, a guide limiting plate 311 is installed on the adjusting plate 303, and the guide limiting plate 311 is vertically arranged. The guide limiting plate 311 can axially limit the falling processing tube 40, thus ensuring that when the processing tube 40 falls into the unloading channel, the processing end is exactly in the area where the right limiting plate 308 is longer than the left limiting plate 312, and there is no axial displacement.

[0044] Furthermore, the conveying module also includes springs 318, which are distributed on both sides of the feed roller 305. One side of the spring 318 abuts against the adjusting plate 303, and the other side of the spring 318 abuts against the end of the rotating shaft 316. The feed roller 305 is slidably connected to the rotating shaft 316.

[0045] Because the processing tubes 40 have varying lengths, springs 318 are used to ensure that the weight at both ends of the processing tube 40 is balanced when the feeding roller 305 supports it. When the adjusting plate 303 is in the adjusted position, it also compresses the springs 318. Since the springs 318 on both sides are of the same specification, the compression is the same. That is, the feeding roller 305 slides on the rotating shaft 316 and is always at the center position between the adjusting plate 303 and the end face of the temporary storage box 302. Figure 4 As shown, at this time, the feeding roller 305 supports the processing tube 40, and the two ends of the processing tube 40 can reach a balanced state.

[0046] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0047] Example 4:

[0048] This embodiment further extends the above embodiment, specifically as follows: Figure 6As shown, the feeding device 10 includes a movable base 101, a support chaff 102, a feeding assembly, and a storage hopper 106. The feeding assembly includes a conveyor frame 103, a conveyor belt 104, and a conveyor roller 105. One end of the conveyor frame 103 is mounted on the movable base 101, and the other end is mounted on the support chaff 102. The support chaff 102 is mounted on the movable base 101. The conveyor roller 105 is rotatably connected to the conveyor frame 103. The conveyor belt 104 is sleeved on the conveyor roller 105. A material-pushing plate 107 is provided on the conveyor belt 104. The height of the material-pushing plate 107 is approximately equal to the diameter of the processing tube 40, so that only one processing tube 40 can be pushed upwards at a time.

[0049] The height of the support 102 is adjustable, thereby adjusting the tilt angle of the conveyor frame 103 and thus adjusting the conveying height. Two conveyor belts 104 are fitted on both sides of the conveyor roller 105 with a gap in the middle. The gap space facilitates the three-axis transfer claw 205 to clamp the processing tube 40. During feeding, the feeding motor drives one conveyor roller 105 to rotate, which in turn makes the conveyor belt 104 run. At this time, the material-pushing plate 107 starts to push one of the processing tubes 40 in the storage hopper 106 and slowly conveys it upward. When it is conveyed to the top, the three-axis transfer claw 205 will clamp the processing tube 40. Then the feeding motor stops running. After the three-axis transfer claw 205 conveys the processing tube 40 on the port leveling unit 201 to the port upsetting unit 202, the feeding motor conveys another processing tube 40 to the top for the three-axis transfer claw 205 to clamp.

[0050] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
