[0056] In order to solve the problem of low efficiency of measuring the length of the U-shaped copper pipe of the heat exchanger by the staff in the prior art, the present application provides a detection equipment.

[0057] As shown in Figures 1 to 23 The detection equipment includes a base 10, a positioning structure 20 and a positioning structure 20. The base 10 is used to carry the to-be-detected piece 1. The positioning structure 20 is movably arranged on the base 10. The detection structure 30 is adjustably arranged on the base 10, so that the detection part 31 of the detection structure 30 abuts against the pipe opening of the to-be-detected piece 1 and detects the length of the to-be-detected piece 1. The positioning structure 20 has a positioning position and a avoiding position. When the positioning structure 20 is in the positioning position, the positioning structure 20 is in contact with the pipe opening to position the to-be-detected piece 1. When the positioning structure 20 is in the avoiding position, the positioning structure 20 avoids the detection part 31.

[0058] The base 10 of the detection device is used for carrying the to-be-detected piece 1. The positioning structure 20 is movably arranged on the base 10. The detection structure 30 is adjustably arranged on the base 10, so that the detection part 31 of the detection structure 30 abuts against the pipe opening of the to-be-detected piece 1 and detects the length of the to-be-detected piece 1. The positioning structure 20 has a positioning position and a avoiding position. When the positioning structure 20 is in the positioning position, the positioning structure 20 abuts against the pipe opening to position the to-be-detected piece 1. When the positioning structure 20 is in the avoiding position, the positioning structure 20 avoids the detection part 31. In this way, when the worker needs to measure the length of the U-shaped copper pipe of the heat exchanger, the worker places the U-shaped copper pipe on the base 10. When the positioning structure 20 is in the positioning position, the positioning structure 20 abuts against the U-shaped copper pipe to position the U-shaped copper pipe, thereby ensuring the accuracy of the placement of the U-shaped copper pipe. Then, the positioning structure 20 is in the avoiding position, the detection structure 30 is adjusted to move to the U-shaped copper pipe, and the length of the U-shaped copper pipe is detected by the detection part 31. This reduces the manual measurement steps of the worker, reduces the working strength of the worker, improves the measurement efficiency of the worker, improves the accuracy of the length measurement of the U-shaped copper pipe, and improves the detection speed and detection efficiency of the detection structure 30, thereby further improving the detection efficiency of the worker on the length of the U-shaped copper pipe.

[0059] In this embodiment, the to-be-detected piece 1 is a U-shaped copper pipe, and the U-shaped copper pipe includes an arc-shaped pipe and a straight pipe connected to both ends of the arc-shaped pipe.

[0060] In this embodiment, the detection structure 30 is a laser displacement sensor.

[0061] As Figure 1 , Figure 7 and Figures 10 to 12As shown, the detection device further comprises a limiting structure 40 movably arranged on the base 10. The limiting structure 40 has a limiting position and a reset position. When the limiting structure 40 is in the limiting position, the limiting structure 40 abuts against the arc-shaped tube of the U-shaped copper pipe away from the pipe opening, so as to limit and stop the to-be-detected piece 1. When the limiting structure 40 is in the reset position, the limiting structure 40 avoids the to-be-detected piece 1. In this way, during the abutting of the detection part 31 against the pipe opening of the straight tube, the limiting structure 40 is in the limiting position, and the limiting structure 40 abuts against the arc-shaped tube of the U-shaped copper pipe, so that the detection part 31 can measure the length of the U-shaped copper pipe with the limiting structure 40 as a reference, thereby ensuring the detection reliability and accuracy of the detection structure 30. When the detection of the length of the U-shaped copper pipe placed on the base 10 is completed, the limiting structure 40 is in the reset position, so that the worker can smoothly place the next batch of U-shaped copper pipes on the base 10, thereby ensuring the smoothness of the U-shaped copper pipes, and improving the detection efficiency of the detection device.

[0062] As shown in Figure 1 , the limiting structure 40 has a limiting recess 41, and the inner wall of the limiting recess 41 is matched with the arc-shaped tube. When the limiting structure 40 is in the limiting position, the detection part 31 abuts against the pipe opening and pushes the arc-shaped tube to move towards the limiting recess 41, so as to limit and stop the to-be-detected piece 1 by the inner wall of the limiting recess 41. In this way, the inner wall of the limiting recess 41 of the limiting structure 40 is matched with the arc-shaped tube of the U-shaped copper pipe, so that the limiting recess 41 can accurately and gently limit and stop the arc-shaped tube, avoiding the damage of the arc-shaped tube due to the hard collision between the limiting structure 40 and the arc-shaped tube, thereby ensuring the structural integrity of the U-shaped copper pipe and the product quality of the U-shaped copper pipe.

[0063] As shown in Figure 3 , Figure 13 , Figure 14 and Figure 1 , the detection device further comprises a bearing structure 50 arranged on the base 10. The bearing structure 50 has a bearing part 511 for bearing the to-be-detected piece 1. In this way, the detection device realizes the bearing of the U-shaped copper pipe through the bearing part 511 of the bearing structure 50, thereby ensuring the stability and reliability of the placement of the U-shaped copper pipe.

[0064] As shown in Figures 13 to 15 , Figures 16 to 18As shown, the detection device further comprises a bearing driving structure 60 arranged on the base 10 and drivingly connected with the bearing structure 50 to drive the bearing structure 50 to move the to-be-detected piece 1 towards or away from the positioning structure 20. In this way, the bearing driving structure 60 drives the bearing structure 50 to move towards or away from the positioning structure 20, so that when the positioning structure 20 is in the positioning position, the contact between the pipe opening of the U-shaped copper pipe and the positioning structure 20 is automated, and after the detection of the detection structure 30 is completed, the automatic resetting of the bearing structure 50 is realized, the operation step of manually pushing the U-shaped copper pipe by the worker is reduced, and the worker is also facilitated to timely place the U-shaped copper pipe on the bearing structure 50, the automation degree of the detection device is improved, the working strength of the worker is reduced, and the working efficiency of the worker is improved.

[0065] In the embodiment, the bearing driving structure 60 comprises a servo motor and a transmission structure, the servo motor is arranged on the base 10, and the transmission structure is arranged at one end of the bearing structure 50 close to the base 10, and the servo motor drives the bearing structure 50 to move through the transmission structure.

[0066] Optionally, the transmission structure is a ball screw.

[0067] In the embodiment, the detection device further comprises a bearing guide rail arranged on the base 10, and the bearing structure 50 is provided with two groups of bearing sliding block structures at one end close to the base 10, and the bearing sliding block structures are slidingly matched with the bearing guide rail to reduce the friction of the bearing structure 50, and the smoothness of the bearing structure 50 is improved.

[0068] Specifically, each group of bearing sliding block structures comprises two bearing sliding block structures, and the two bearing sliding block structures are arranged at intervals along the extension direction of the sliding rail to balance the stress of the bearing structure 50 and ensure the running stability of the bearing structure 50.

[0069] As Figure 2As shown, the bearing part 511 has two bearing holes 5111, which are arranged at intervals along the first preset direction, and are respectively used for the two straight pipes of the to-be-detected piece 1 to pass through. Among them, the detection part 31 is two, which abuts against the pipe openings of the two straight pipes. In this way, the bearing part 511 realizes the bearing of the two straight pipes of the U-shaped copper pipe through the two bearing holes 5111, which guarantees the bearing reliability of the bearing part 511. At the same time, the straight pipes of the U-shaped copper pipe pass through the bearing holes 5111, so that the hole walls of the bearing holes 5111 can limit and stop the straight pipes of the U-shaped copper pipe, avoiding the phenomenon that the U-shaped copper pipe shakes and deviates under the action of external force, guaranteeing the bearing stability of the bearing part 511, and also guaranteeing the detection accuracy of the detection equipment. At the same time, the two detection parts 31 can correspondingly abut against the pipe openings of the two straight pipes of the U-shaped copper pipe, so that the detection structure 30 can detect the lengths of the two straight pipes of the U-shaped copper pipe at the same time, improving the detection efficiency of the detection structure 30, and further improving the detection efficiency of the detection equipment.

[0070] As shown in Figure 13 , the detection structure 30 further comprises an elastic piece 32, which is connected to one end of the detection part 31 away from the bearing structure 50, so as to compensate for the distance difference between the two pipe openings during the abutment of the two detection parts 31 and the two pipe openings. In this way, during the abutment of the two detection parts 31 of the detection structure 30 and the two pipe openings of the U-shaped copper pipe and the abutment of the U-shaped copper pipe and the limiting structure 40, once the lengths of the two straight pipes of the U-shaped copper pipe are inconsistent, the elastic piece 32 can compensate for the deviation of the two straight pipes, avoiding the phenomenon that one of the straight pipes is too long and the other straight pipe cannot abut against the detection part 31, guaranteeing the detection accuracy and reliability of the detection structure 30. At the same time, the setting mode of the elastic piece 32 can also buffer the detection part 31, avoiding the phenomenon that the detection part 31 shakes or is damaged due to the action of external force, achieving the protection of the detection part 31, and prolonging the service life of the detection part 31.

[0071] In this embodiment, the elastic piece 32 is a spring.

[0072] As shown in Figure 16 and Figure 16 , the bearing structure 50 comprises a bearing piece 51, which is plate-shaped and has a bearing part 511. Among them, the bearing part 511 is multiple, which is arranged at intervals along the length direction or width direction of the bearing piece 51. In this way, the bearing structure 50 realizes the bearing of the U-shaped copper pipe through the bearing piece 51, and the bearing piece 51 realizes the bearing of multiple U-shaped copper pipes through the multiple bearing parts 511, so that multiple U-shaped copper pipes can contact the positioning structure 20 at the same time, achieving the preliminary positioning of multiple U-shaped copper pipes, and enabling the detection structure 30 to detect multiple U-shaped copper pipes, improving the detection efficiency of the detection structure 30.

[0073] In the embodiment, as shown in Figure 1 , the carrier 51 is in the shape of a rectangular plate, and a plurality of carrier portions 511 are arranged at intervals along the length direction of the carrier 51. Meanwhile, the first preset direction is consistent with the length direction of the carrier 51.

[0074] In the embodiment, the limiting structure 40 is in the shape of a cuboid, and a plurality of limiting recesses 41 are arranged at intervals along the length direction of the limiting structure 40. When the limiting structure 40 is in the limiting position, the plurality of limiting recesses 41 can accommodate the arc-shaped tubes of the plurality of U-shaped copper tubes, thereby ensuring the detection reliability and accuracy of the plurality of U-shaped copper tubes.

[0075] In the embodiment, in the process of detecting the plurality of U-shaped copper tubes, the detection structure 30 records the length data of the plurality of U-shaped copper tubes, compares the detected length data with the standard value, and records the qualified length and the unqualified length, so that the unqualified U-shaped copper tubes can be placed in the unqualified area when the plurality of U-shaped copper tubes enter the next process.

[0076] As shown in Figures 19 to 20 , Figure 1 , the detection device further comprises a first sliding assembly 70 and a second sliding assembly 80. The first sliding assembly 70 comprises a first sliding rail structure 71 and a first sliding block structure 72, the first sliding rail structure 71 is arranged on the base 10 and extends along the second preset direction, and the first sliding block structure 72 is in sliding cooperation with the first sliding rail structure 71.

Among them, the second preset direction and the third preset direction are arranged at an included angle. In this way, the first sliding assembly 70 can drive the second sliding assembly 80 to slide along the second preset direction, thereby driving the detection structure 30 to slide along the second preset direction. Meanwhile, the second sliding assembly 80 can drive the detection structure 30 to slide along the third preset direction, so that the detection structure 30 can be slidably arranged from the second preset direction and the third preset direction, so that the activity range of the detection structure 30 is more abundant, the detection range of the detection structure 30 is expanded, the detection versatility of the detection structure 30 is improved, so that the same detection structure 30 can detect the length of the plurality of U-shaped copper tubes, which reduces the detection cost, and further improves the detection efficiency and detection versatility of the detection device. Meanwhile, the setting mode of the first sliding assembly 70 and the second sliding assembly 80 can reduce the sliding resistance of the detection structure 30, and improve the sliding smoothness and sliding reliability of the detection structure 30.

[0077] In the embodiment, as shown in Figure 1 , the detection device further comprises a first sliding assembly 70 and a second sliding assembly 82. The first sliding assembly 70 comprises a first sliding rail structure 71 and a first sliding assembly 72, the first sliding rail structure 71 is arranged on the base 10 and extends in the second preset direction, and the first sliding block structure 72 is in sliding cooperation with theAs shown, the first preset direction is consistent with the length direction of the bearing 51, the second preset direction is arranged in parallel with the first preset direction, and the third preset direction is arranged perpendicularly in the same plane as the second preset direction.

[0078] In the embodiment, the first sliding assembly 70 and the second sliding assembly 80 are both linear modules.

[0079] In the embodiment, two first sliding rail structures 71 are arranged, and the first sliding block structure 72 is in sliding connection with the two first sliding rail structures 71 in the third preset direction, so as to balance the stress of the detection structure 30 and improve the sliding smoothness of the first sliding block structure 72.

[0080] As shown in Figure 9 and ​ As shown, the detection device further comprises a positioning driving structure 90 arranged on the base 10 and in driving connection with the positioning structure 20 to drive the positioning structure 20 to move towards or away from the base 10, and / or the detection device further comprises a limiting driving structure 100 arranged on the base 10 and in driving connection with the limiting structure 40 to drive the limiting structure 40 to move towards or away from the base 10. In this way, the positioning driving structure 90 drives the positioning structure 20 to switch between the positioning position and the avoiding position, avoiding manual adjustment by the staff, reducing the labor intensity of the staff, improving the operation automation degree of the positioning structure 20, and further improving the automation degree of the detection device. At the same time, the limiting driving structure 100 drives the limiting structure 40 to switch between the limiting position and the reset position, avoiding manual adjustment by the staff, reducing the labor intensity of the staff, improving the operation automation degree of the limiting structure 40, and further improving the automation degree of the detection device.

[0081] In the embodiment, the positioning structure 20 is in the shape of a cuboid, and the positioning driving structure 90 is three, which are arranged at intervals along the length direction of the positioning structure 20 to balance the stress of the positioning structure 20.

At this time, the limiting driving structure 100 drives the limiting structure 40 to move to the limiting position, then the detection structure 30 moves horizontally to the U-shaped copper pipe to be detected through the first sliding assembly 70, then the second sliding assembly 80 drives the detection structure 30 to move towards the pipe opening of the U-shaped copper pipe, after the detection part 31 of the detection structure 30 abuts against the pipe opening of the U-shaped copper pipe, drives the U-shaped copper pipe to abut against the limiting recess 41 of the limiting structure 40, then detects the lengths of the two straight pipes of the U-shaped copper pipe, and compares the measured length data with the standard value, so as to calibrate the U-shaped copper pipe as qualified products and unqualified products. After the plurality of U-shaped copper pipes on the bearing 51 are all detected, the limiting driving structure 100 drives the limiting structure 40 to move to the reset position, the bearing driving structure 60 drives the bearing structure 50 to move the plurality of U-shaped copper pipes away from the positioning structure 20 to the initial position, the worker correspondingly places the qualified U-shaped copper pipes in the qualified area, and places the unqualified U-shaped copper pipes in the unqualified area, thus the detection equipment completes the whole detection process.

The detection structure is adjustably arranged on the base, so that the detection part of the detection structure abuts against the pipe opening of the to-be-detected piece and detects the length of the to-be-detected piece. The positioning structure has a positioning position and a avoiding position. When the positioning structure is in the positioning position, the positioning structure abuts against the pipe opening to position the to-be-detected piece. When the positioning structure is in the avoiding position, the positioning structure avoids the detection part. In this way, when a worker needs to measure the length of the U-shaped copper pipe of the heat exchanger, the worker places the U-shaped copper pipe on the base. At this time, the positioning structure is in the positioning position, the positioning structure abuts against the U-shaped copper pipe to position the U-shaped copper pipe, and the placement accuracy of the position of the U-shaped copper pipe is ensured. Then, the positioning structure is in the avoiding position, the detection structure is adjusted to move to the position of the U-shaped copper pipe, and the length of the U-shaped copper pipe is detected by the detection part. The steps of manual measurement of the worker are reduced, the working strength of the worker is reduced, the measurement efficiency of the worker is improved, and the accuracy of the length measurement of the U-shaped copper pipe is improved. Meanwhile, the positioning structure is arranged in the manner, which can preliminarily position the U-shaped copper pipe, ensure that the U-shaped copper pipe is in the correct starting position in the subsequent measurement process, improve the detection speed and detection efficiency of the detection structure, and further improve the detection efficiency of the worker on the length of the U-shaped copper pipe.
