[0044] Combination Figure 1 and Figure 2 The embodiment of the utility model provides a fully automatic DCT testing device, including: a first conveyor line 1, a second conveyor line 6, a detection circulation line 2, two grabbing mechanisms 3 and a DCT testing device 4; the detection circulation line 2 is located on one side of the first conveyor line 1; the DCT testing device 4 is located on one side of the detection circulation line 2, the first conveyor line 1 is used to convey the workpiece to be tested 7 and the workpiece 7 that has passed the test, and the second conveyor line 6 is used to convey the workpiece 7 that has failed the test; the second conveyor line 6 is located on one side of the first conveyor line 1; a grabbing mechanism 3 moves between the first conveyor line 1 and the detection circulation line 2 and is used to grab the workpiece to be tested 7; the DCT testing device 4 is used to test the workpiece to be tested 7 on the detection circulation line 2; another grabbing mechanism 3 moves between the first conveyor line 1, the detection circulation line 2 and the second conveyor line 6 and is used to grab the tested workpiece 7.

[0045] In this embodiment, the detection circulation line 2 can be located above the first conveyor line 1 so that the air-conditioning electrical box transported by the first conveyor line 1 will pass through the bottom of the detection circulation line 2. A grabbing mechanism 3 is located between the first conveyor line 1 and the detection circulation line 2. The air-conditioning electrical box (workpiece 7) on the first conveyor line 1 is grabbed onto the detection circulation line 2 by the grabbing mechanism 3. The DCT testing equipment 4 is located in the conveying direction of the detection circulation line 2. When the air-conditioning electrical box on the detection circulation line 2 passes through the DCT testing equipment 4, the DCT testing equipment 4 performs a DCT test on the air-conditioning electrical box, and the air-conditioning electrical box after the DCT test continues to be transported on the detection circulation line 2; another grabbing mechanism 3 is located between the first conveyor line 1, the detection circulation line 2 and the second conveyor line 6. When the air-conditioning electrical box after the DCT test reaches another grabbing mechanism 3, the grabbing mechanism 3 grabs the air-conditioning electrical box after the DCT test and places it on the first conveyor line 1 or the second conveyor line 6.

[0046] In this embodiment, the conveying line of the detection circulation line 2 is a closed ring conveying, so that the air-conditioning electrical box is conveyed on the detection circulation line 2 in a reciprocating manner. Only when the grabbing mechanism 3 detects that the air-conditioning electrical box on the detection circulation line 2 has undergone the DCT test, the grabbing mechanism 3 will grab the air-conditioning electrical box from the detection circulation line 2 and place it on the first conveying line 1 or the second conveying line 6, and the air-conditioning electrical box that has not been tested by the DCT test equipment 4 will continue to move in a circular manner on the detection circulation line 2 until it has been tested by the DCT test equipment 4, and then it can be grabbed by the grabbing mechanism 3 from the detection circulation line 2 and placed on the first conveying line 1 or the second conveying line 6. Through such a setting, it can be ensured that each air-conditioning electrical box on the detection circulation line 2 undergoes the DCT test, thereby distinguishing qualified and unqualified air-conditioning electrical boxes, which is conducive to avoiding the situation of confusing unqualified products with qualified products, and improving the production efficiency of air-conditioning electrical boxes.

[0047] In this embodiment, since the test time of the DCT test device 4 is relatively long, multiple DCT test devices 4 can be set, and the multiple DCT test devices 4 are distributed around the side of the detection loop line 2. When there are many air-conditioning electrical boxes on the detection loop line 2, multiple DCT test devices 4 improve the DCT test efficiency of the air-conditioning electrical boxes.

[0049] In this embodiment, the detection clamping mechanism 5 is distributed around the side of the detection circulation line 2. When there are multiple DCT test devices 4, the multiple DCT test devices 4 can be distributed around the periphery of the detection clamping mechanism 5, so that the detection clamping mechanism 5 can grab the air-conditioning electrical box on the detection circulation line 2 to each DCT test device 4.

[0052] In this embodiment, the mounting frame includes a first mounting frame 21, a second mounting frame 22 and a plurality of support frames 23. The first mounting frame 21 and the second mounting frame 22 are arranged at intervals in the conveying direction of the first conveyor line 1. The plurality of support frames 23 are arranged between the first mounting frame 21 and the second mounting frame 22. The first mounting frame 21, the second mounting frame 22 and the plurality of support frames 23 are all located above the first conveyor line 1. The annular track assembly 24 is arranged on the first mounting frame 21, the second mounting frame 22 and the plurality of support frames 23 so that the annular track assembly 24 is located above the first conveyor line 1. Through such an arrangement, the annular track assembly 24 and the first conveyor line 1 do not interfere with each other, and it is also convenient for the grasping mechanism 3 to place the air-conditioning electrical box of the first conveyor line 1 on the workpiece position 243 of the annular track assembly 24.

[0053] In this embodiment, the driving assembly 25 is connected to the circular track assembly 24 to provide the circular track assembly 24 with the power required for rotating in a circular direction, ensuring that the multiple air-conditioning electrical boxes located on the circular track assembly 24 can automatically move to the position of the DCT testing equipment 4, and then the DCT testing equipment 4 tests the air-conditioning electrical boxes. The tested air-conditioning electrical boxes are then moved to the grabbing mechanism 3 located between the first conveyor line 1, the circular track assembly 24 and the second conveyor line 6 through the circular conveyance of the circular track assembly 24, so that the grabbing mechanism 3 grabs the air-conditioning electrical boxes from the circular track assembly 24, and then places them on the first conveyor line 1 or the second conveyor line 6 according to the qualified and unqualified test results.

[0054] In one embodiment, the annular track assembly 24 includes an annular conveying member 241, an annular guide rail 242 and a plurality of tooling seats; the annular conveying member 241 is arranged on the annular inner side of the annular guide rail 242, a plurality of tooling seats are slidably assembled on the annular guide rail 242, and the annular conveying member 241 is connected to the plurality of tooling seats; the driving assembly 25 is used to drive the annular conveying member 241 to transmit along the annular direction.

The annular guide rail 242 passes between the two rollers 2435 and is clamped in the recessed groove, so that the tooling seat and the annular guide rail 242 can be stably slidably installed, and the tooling seat can roll on the annular guide rail 242 through the rollers 2435.

[0056] In a more specific embodiment, a plurality of connecting members 2412 are arranged along the annular direction on the annular conveyor 241, and the plurality of connecting members 2412 are respectively connected to a plurality of tooling seats one by one. A connecting groove 2436 is also provided on the lower positioning plate 2432, and the connecting member 2412 is connected to the connecting groove 2436. Through such an arrangement, when the driving assembly 25 drives the annular conveyor 241 to rotate in the annular direction, the annular conveyor links the tooling seat through the connecting member 2412, thereby enabling the tooling seat to roll on the annular guide rail 242.

[0057] In one embodiment, the driving assembly 25 may be a gear driving structure, a roller transmission structure or other similar transmission forms, as long as it can rotate along a ring to drive the ring track to rotate. The specific structure and working principle of the gear driving structure and the roller transmission structure are described in detail below:

[0058] In the first gear drive structure, the annular transmission member 241 is a chain transmission structure mounted on the driving assembly 25 .

[0059] In this embodiment, the gear drive structure includes a motor 251 and two gears 252, the two gears 252 are rotatably mounted on the first mounting frame 21 and the second mounting frame 22 respectively, the chain 2411 in the chain transmission structure is connected at both ends to form an annular chain 2411, the inner side of the annular chain 2411 is meshed and connected to the two gears 252, the output end of the motor 251 can be connected to any gear 252 to drive the gear 252 to rotate, so that the gear 252 links the chain 2411 to rotate in the annular direction. Among them, the connecting member 2412 is arranged on the outer side of the annular chain 2411, so that the connecting groove 2436 of the tooling seat can be connected to the connecting member 2412.

[0060] More specifically, the chain transmission structure further includes a chain track 2413 , which is disposed on a plurality of support frames 23 , and the chain 2411 is slidably assembled on the chain track 2413 to enhance the rotation stability of the chain 2411 .

Among them, the connecting member 2412 is arranged on the outer side of the belt so that the connecting groove 2436 of the tooling seat can be connected to the connecting member 2412.

[0063] Combination Figure 7 , the grabbing mechanism 3 is introduced in more detail below.

[0064] In one embodiment, the gripping mechanism 3 includes a driving member, a clamping claw 36 and a first scanner 37; the driving member is mounted on a mounting frame, and the clamping claw 36 and the first scanner 37 are mounted on the driving member;

[0065] Among them, the driving member of one grasping mechanism 3 moves between the first conveyor line 1 and the detection circulation line 2; the driving member of another grasping mechanism 3 moves between the first conveyor line 1, the detection circulation line 2 and the second conveyor line 6 and is used to grasp the workpiece to be tested 7; the clamp 36 is used to clamp the workpiece to be tested 7, and the first scanner 37 is used to scan the workpiece position 243.

[0066] In this embodiment, the first mounting frame 21 can correspond to the upstream conveying end of the first conveyor line 1 (for conveying the workpiece 7 to be tested), the second mounting frame 22 and the second conveyor line 6 can correspond to the downstream conveying end of the first conveyor line 1 (for conveying the tested workpiece 7 to the subsequent link), and the two grasping mechanisms 3 are respectively arranged on the first mounting frame 21 and the second mounting frame 22, and the detection clamping mechanism 5 and the DCT test equipment 4 are arranged on one side of the detection circulation line 2 between the two grasping mechanisms 3; through such an arrangement, when the air conditioner electrical box conveyed on the first conveyor line 1 reaches the first mounting frame 21, the first grasping mechanism 3 located on the first mounting frame 21 can grasp Take the air-conditioning electrical box and place it on the detection circulation line 2; when the air-conditioning electrical box is transported to the detection clamping mechanism 5 on the detection circulation line 2, the detection clamping mechanism 5 clamps the air-conditioning electrical box and places it on the DCT test equipment 4 for DCT testing. After the test of the DCT test equipment 4 is completed, the detection clamping mechanism 5 clamps the air-conditioning electrical box from the DCT test equipment 4 and puts it back on the detection circulation line 2; the air-conditioning electrical box after the test is completed is then transported from the detection circulation line 2 to the grasping mechanism 3 located on the second mounting frame 22, and the grasping mechanism 3 on the second mounting frame 22 grasps the air-conditioning electrical box according to the DCT test result of the air-conditioning electrical box and places it on the first conveyor line 1 or the second conveyor line 6.

[0067] Among them, the grabbing mechanism 3, the detection clamping mechanism 5 and the DCT testing equipment 4 are all communicatively connected with the control system in the fully automatic DCT testing device of the present application, so as to be used for mutual signal transmission between the grabbing mechanism 3, the detection clamping mechanism 5 and the DCT testing equipment 4; through such a setting, when the air-conditioning electrical box transported on the first conveyor line 1 arrives at the first mounting rack 21, first, the control system can control the clamping claw 36 of the grabbing mechanism 3 to grab the air-conditioning electrical box, and then the control system scans the workpiece position 243 on the detection circulating track through the first scanner 37 to identify whether the workpiece position 243 is vacant, and chooses to place the air-conditioning electrical box or wait for the next workpiece position 243 to place the air-conditioning electrical box according to the vacancy situation.

[0068] In a more specific embodiment, the two gripping mechanisms 3 in this embodiment have the same structural principle, and the driving parts in the gripping mechanism 3 include multiple cylinders integrated into one body, and the multiple cylinders are respectively oriented in multiple directions to drive the clamp 36 and the first scanner 37 to move in multiple directions.

[0069] In this embodiment, multiple cylinders allow the clamp 36 and the first scanner 37 to move in multiple directions in space, thereby improving the accuracy and convenience of the clamp 36 grabbing the air conditioner electrical box and the first scanner 37 scanning the workpiece position 243.

[0070] Specifically, five cylinders can be provided, including a first cylinder 31, a second cylinder 32, a third cylinder 33, a fourth cylinder 34 and a fifth cylinder 35, wherein the first cylinder 31 and the second cylinder 32 are respectively provided on opposite sides of the first mounting frame 21, both ends of the third cylinder 33 are respectively slidably assembled on the two first cylinders 31 and the second cylinder 32, the fourth cylinder 34 is slidably assembled along the length direction of the third cylinder 33, the fifth cylinder 35 is slidably assembled on the fourth cylinder 34 along the height direction of the first mounting frame 21, and the clamp 36 and the first scanner 37 are installed on the fifth cylinder 35; through such an arrangement, the clamp 36 and the first scanner 37 can move left and right, front and back, and up and down, thereby ensuring the convenience of adjusting the position of the clamp 36 and the first scanner 37.

[0071] Combination Figure 6 In a more specific embodiment, the detection and clamping mechanism 5 includes a multi-axis robot arm 51, a slide cylinder 52, a fixture cylinder 53, a fixture 54 and a second scanner 55; the slide cylinder 52 is arranged at the free end of the multi-axis robot arm 51, the fixture cylinder 53 and the second scanner 55 are arranged on the output end of the slide cylinder 52, and the fixture 54 is arranged at the output end of the fixture cylinder 53; the fixture cylinder 53 is used to drive the clamping movement of the fixture 54, and the second scanner 55 is used to scan and identify the test records of the workpiece 7.

[0072] In this embodiment, when it is necessary to clamp the air-conditioning electrical box, the multi-axis robotic arm 51 controls the slide cylinder 52 to move to the air-conditioning electrical box so that the air-conditioning electrical box is within the clamping range of the clamp 54. At this time, the clamping cylinder drives the clamp 54 to relatively clamp the air-conditioning electrical box and moves to the DCT testing equipment 4 under the control of the multi-axis robotic arm 51. At this time, the clamping cylinder drives the clamp 54 to open so that the air-conditioning electrical box is placed on the DCT testing equipment 4 for DCT testing.

[0073] Before the control system controls the clamp 54 to clamp the air-conditioning electrical box, it is first necessary to scan the code on the air-conditioning electrical box through the second scanner 55 to identify whether the air-conditioning electrical box has undergone a DCT test and upload it to the control system. If the air-conditioning electrical box has undergone a DCT test, the control system controls the clamp 54 not to clamp the air-conditioning electrical box. If the air-conditioning electrical box has not undergone a DCT test, the air-conditioning electrical box is clamped and placed on the DCT test device 4 for testing. After the DCT test device 4 completes the test, the test result is uploaded to the control system, and then the multi-axis robot arm 51 clamps the air-conditioning electrical box from the DCT test device 4 and puts it back on the detection circulation line 2; the detection circulation line 2 conveys the air-conditioning electrical box to the second mounting rack 22, and the control system controls the first scanner 37 of the gripping mechanism 3 on the second mounting rack 22 to scan the code of the air-conditioning electrical box, thereby obtaining the test result of the air-conditioning electrical box, and the test result includes qualified and unqualified. The control system controls the gripping mechanism 3 to place the qualified air-conditioning electrical box on the first conveyor line 1 and the unqualified air-conditioning electrical box on the second conveyor line 6.

[0074] It should be noted that when the first scanner 37 does not recognize the test result of the air-conditioning electrical box, the grasping mechanism 3 does not grasp the air-conditioning electrical box, so that the air-conditioning electrical box continues to move in a cycle on the detection circulation line 2, and then continues to wait for scanning the next air-conditioning electrical box, and repeats this cycle, thereby ensuring that the fully automatic DCT testing device can automatically grasp the air-conditioning electrical box to the detection circulation line 2, automatically perform the DCT test, and finally automatically place the air-conditioning electrical box on the first conveyor line 1 and the second conveyor line 6 according to the qualified or unqualified test results. In this way, automatic DCT testing of the air-conditioning electrical box is realized, and fatigue caused by long-term manual operation is avoided, which leads to confusion between qualified and unqualified air-conditioning electrical boxes, which is conducive to reducing labor costs and improving the automation function of the DCT test of the air-conditioning electrical box.

[0075] In this embodiment, the multi-axis robot arm 51 is disposed on the ground on one side close to the detection loop line 2 through a base, and can also be directly disposed on the detection loop line 2.

[0076] The present utility model also provides a testing method for a fully automatic DCT testing device, such as Figure 8 As shown, the method includes steps S101 to S104:

[0077] S101, conveying the workpiece 7 to be tested through the first conveyor line 1;

[0078] S102, gripping the workpiece 7 to be tested on the first conveying line 1 by a gripping mechanism 3 and transferring it to the inspection circulation line 2;

[0079] S103, testing the workpiece 7 to be tested on the detection cycle line 2 by the DCT testing device 4 and determining whether it is qualified;

[0080] S104 , gripping the qualified tested workpiece 7 and transferring it to the first conveying line 1 through another gripping mechanism 3 , and gripping the unqualified tested workpiece 7 and transferring it to the second conveying line 6 .

[0081] In this embodiment, the detection loop line 2 can be located above the conveying direction of the first conveyor line 1, so that the workpiece 7 to be tested conveyed on the first conveyor line 1 can be conveyed to the vicinity of the detection loop line 2, and the two grasping mechanisms 3 are respectively located upstream of the first conveyor line 1 near the detection loop line 2 and downstream of the first conveyor line 1 near the detection loop line 2. When the workpiece 7 to be tested is close to a grasping mechanism 3 at the detection loop line 2, the grasping mechanism 3 can grasp the workpiece 7 to be tested, and then place the grasped workpiece 7 to be tested on the detection loop line 2 for conveyance; wherein, the DCT test equipment 4 is arranged on the side of the detection loop line 2 and is located between the two grasping mechanisms 3, so that the workpiece 7 to be tested is first placed on the detection loop line 2 by a grasping mechanism 3, and then confirmed. Ensure that the workpiece 7 to be tested passes the DCT test and is then conveyed to the position of another grabbing mechanism 3 by the detection circulation line 2. The other grabbing mechanism 3 places the qualified workpieces 7 to be tested after the DCT test on the first conveyor line 1 and the unqualified ones on the second conveyor line 6 according to the test results. Through such a setting, it is ensured that the workpiece 7 to be tested can be automatically grabbed and put on the detection circulation line 2, and then after the DCT test of the DCT testing equipment 4, the grabbing mechanism 3 automatically places the tested workpiece 7 on the first conveyor line 1 or the second conveyor line 6 according to the test results, thereby effectively reducing the labor cost and avoiding the qualified workpiece 7 and the unqualified workpiece 7 being mixed up on the first conveyor line 1 or the second conveyor line 6 due to fatigue during manual operation.

[0082] Among them, when there are many workpieces 7 on the detection loop line 2, the test position of the DCT test equipment 4 is fully occupied because the test time of the DCT test equipment 4 is long. When other workpieces 7 pass through the DCT test equipment 4, the DCT test equipment 4 does not have time to perform DCT tests on other workpieces 7, which will cause the workpieces 7 on the detection loop line 2 to gradually accumulate, and the workpieces 7 that are not tested by the DCT test equipment 4 in time will continue to move on the detection loop line 2 to the position of another gripping mechanism 3. If the other gripping mechanism 3 does not obtain the qualified or unqualified information of the workpiece 7, then the other gripping mechanism 3 will be 3 does not grab, so that the workpiece 7 moves in a circle on the detection circulation line 2 until it passes through the DCT testing device 4 again. After the DCT testing device 4 tests the workpiece 7, the other grabbing mechanism 3 can obtain the qualified or unqualified information of the workpiece 7, so that the workpiece 7 can be grabbed and unloaded to the first conveyor line 1 or the second conveyor line 6; through such a setting of the detection circulation line 2, it is ensured that each workpiece 7 to be tested on the detection circulation line 2 can be subjected to the DCT test, and it is avoided that the other grabbing mechanism 3 confuses the qualified and unqualified workpieces 7 to the first conveyor line 1 or the second conveyor line 6.

[0083] In one embodiment, if Fig. 9 As shown, step S102 includes:

[0084] S201, controlling the driving member to drive the clamp 36 and the first scanner 37 to move to the first conveyor line 1 and to clamp the workpiece 7 to be tested through the clamp 36;

[0085] S202, controlling the driving member to drive the clamp 36 and the first scanner 37 to move above the detection circulation line 2, and using the first scanner 37 to scan whether the workpiece position 243 is empty;

[0086] S203, if yes, place the workpiece 7 to be tested in the empty workpiece position 243 through the clamp 36;

[0087] S204, if not, wait for the next workpiece position 243.

[0088] In this embodiment, there are multiple workpiece positions 243 on the detection circulation line 2. When the workpiece 7 is not tested by the DCT testing equipment 4 in time on the detection circulation line 2, the workpiece 7 on the workpiece position 243 will be circulated and moved. When the workpiece 7 is circulated and moved to the position where the gripping mechanism 3 places the workpiece 7 on the detection circulation line 2, in order to avoid repeated stacking of more than two workpieces 7 on the workpiece position 243, after the driving member drives the clamp 36 to clamp the workpiece 7, before placing it on the workpiece position 243, the workpiece position 243 to be placed is scanned by the first scanner 37. If the workpiece position 243 is occupied by other workpieces 7, the clamp 36 does not move, waiting for the arrival of the next workpiece position 243, and then the workpiece position 243 is scanned by the first scanner 37. If the workpiece position 243 is vacant, the workpiece 7 clamped by the clamp 36 is released to be placed on the workpiece position 243. Through such a setting, repeated stacking of the workpiece position 243 is avoided, and the normal operation of the fully automatic DCT testing device is ensured.

[0089] In one embodiment, if Fig.10 As shown, S104 includes:

[0090] S301, control the driving member to drive the clamp 36 and the first scanner 37 to move above the detection cycle line 2, and use the first scanner 37 to scan the workpiece 7 on the workpiece position 243 and identify whether it is a tested workpiece 7,

[0091] S302, if yes, then clamp the tested workpiece 7 and obtain the test result;

[0092] S303, if not, wait for the next workpiece 7;

[0093] S304, when the test result of the clamped tested workpiece 7 is qualified, the clamping claw 36 is driven by the driving member to transfer the tested workpiece 7 to the first conveying line 1;

[0094] S305 , when the test result of the clamped tested workpiece 7 is unqualified, the clamping claw 36 is driven by the driving member to transfer the tested workpiece 7 to the second conveying line 6 .

[0095] In this embodiment, after the workpiece 7 on the detection loop line 2 undergoes the DCT test, the grasping mechanism 3 located on the first conveyor line 1 downstream of the detection loop line 2 first identifies the code of the workpiece 7 through the first scanner 37, and obtains the test result of the workpiece 7, wherein the test result includes qualified and unqualified; then the grasping mechanism 3 grasps the workpiece 7, and places the qualified workpiece 7 on the first conveyor line 1 and the unqualified workpiece 7 on the second conveyor line 6 according to the test results.

[0096] In this embodiment, when the first scanner 37 does not obtain the test result of the workpiece 7, it means that the workpiece 7 has not been tested by DCT, and the clamp 36 of the gripping mechanism 3 does not move, so that the workpiece 7 continues to move on the detection cycle line 2 until it passes the DCT test.

[0097] It should be noted that the gripping mechanism 3 is communicatively connected with the DCT testing device 4 , so that after the DCT testing device 4 tests the workpiece 7 , the gripping mechanism 3 can identify the test result of the workpiece 7 through the first scanner 37 .

[0098] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the testing method described above can refer to the corresponding process of the testing device in the aforementioned method embodiment, and will not be repeated here.

[0099] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
