[0046] Referring to Figure 1 As shown in the drawings, the present application proposes a motor load test equipment 100, which comprises a rack 10, and a test device 20, a positioning assembly 30, a feeding device 40 and a discharging device 50 arranged on the rack 10; the test device 20 is arranged side by side along the length direction of the rack 10, and at least two groups are arranged; the number of the positioning assembly 30 corresponds to the number of the test device 20, and is arranged in abutment with each test device 20; the feeding device 40 comprises a moving module arranged on the rack 10 and a grabbing module 44 connected to the moving module, the moving path of the moving module covers the positioning assembly 30, and the grabbing module 44 is used for grabbing the motor; the number of the discharging device 50 corresponds to the number of the positioning assembly 30, and is arranged in abutment with the positioning assembly 30 on the rack 10, and the discharging device 50 is used for discharging the tested motor.

[0047] In the technical solution of the present application, the test device 20 is an existing product, which can establish a test connection with the positioned motor after the motor is positioned. Among them, one test device 20 can realize the load test of one motor, and the number of test devices 20 arranged on the rack 10 is the number of motors that can be simultaneously tested by the motor load test equipment 100 of the present application.

[0048] In order to simultaneously realize the load test of multiple test devices 20, the present application further sets the positioning assembly 30, the feeding device 40 and the discharging device 50. Among them, the positioning assembly 30 is to realize the positioning of the motor, so as to facilitate the abutment of the test device 20 and the motor. In the specific arrangement, one test device 20 is correspondingly arranged with one positioning assembly 30 to position the motor, and when the feeding device 40 is arranged, only one feeding device 40 can be arranged to abut each positioning assembly 30, which is used for feeding the motor on each positioning assembly 30, and discharging the motor through the discharging device 50 corresponding to each positioning assembly 30.

[0049] Referring to Figure 1 and Figure 2As shown in some embodiments, the positioning assembly 30 comprises a positioning block and a rotating pressing block 33; the positioning block comprises a first positioning block 31 and a second positioning block 32 arranged in parallel and spaced apart, a clearance is formed between the first positioning block 31 and the second positioning block 32, and a positioning groove 311 adapted to the motor shell is formed at the top end of the first positioning block 31 and the second positioning block 32; the rotating pressing block 33 is arranged opposite to the positioning block, and is used to press the motor from above after the motor is placed on the positioning block.

[0050] In this embodiment, the first positioning block 31 and the second positioning block 32 are vertical plate structures, and the positioning groove 311 formed at the top of the first positioning block 31 and the second positioning block 32 can form a good limiting effect on the motor placed thereon. Generally, the groove depth of the positioning groove 311 does not exceed half the thickness of the motor, which facilitates the placement of the motor in the positioning groove 311 by the grabbing assembly.

[0051] Among them, one of the first positioning block 31 and the second positioning block 32 supports the front end of the motor, and the other supports the rear end of the motor, that is, the first positioning block 31 and the second positioning block 32 jointly support and position the motor. A clearance is left between the first positioning block 31 and the second positioning block 32 to cooperate with the blanking device 50 to realize the blanking of the motor.

[0052] Further, the rotating pressing block 33 is arranged opposite to the positioning block, and the action process of the rotating pressing block 33 comprises: after the motor is placed on the positioning block, the rotating pressing block 33 is rotated to above the motor, and then the rotating pressing block 33 is moved downward to cooperate with the positioning block below to fix the motor. In this way, the load test of the motor can be carried out after the motor is stabilized.

[0053] As shown in Figure 1 , Figure 3 and Figure 4 in some embodiments, the moving module comprises a horizontal moving module 41, a vertical moving module 42 and a rotating conversion module 43; the horizontal moving module 41 is arranged opposite to each positioning assembly 30 on the rack 10; the vertical moving module 42 is connected to the horizontal moving module 41 to follow the driving of the horizontal moving module 41 to move horizontally and can provide a downward driving force; the rotating conversion module 43 is connected to the vertical moving module 42 to follow the driving of the vertical moving module 42 to move vertically and can provide a rotating driving force in the horizontal plane; the grabbing module 44 is connected to the rotating conversion module 43 to follow the driving of the rotating conversion module 43 to rotate in the horizontal plane.

[0054] In the embodiment, when the horizontal moving module 41 moves across each positioning assembly 30 on the rack 10, the vertical moving module 42 is driven to move above each positioning assembly 30. It can be understood that the horizontal moving module 41 also interfaces with a previous processing device, and the previous processing device provides an assembled motor to be tested. After the vertical moving module 42 moves in the vertical direction, the motor can be gripped and placed by the gripping module 44.

[0055] The rotating conversion module 43 is further provided and connected with the vertical moving module 42. The gripping module 44 is connected with the rotating conversion module 43, and the gripping module 44 rotates the motor gripped by the gripping module 44 in the horizontal plane to adjust the direction of the motor to be tested by the testing device 20, so as to facilitate the load test after the motor is placed on the positioning assembly 30.

[0056] Referring to Figure 4 In some embodiments, the gripping module 44 includes a first gripper 441, a second gripper 442, and a first driving member that drives the first gripper 441 and the second gripper 442 to move towards or away from each other.

[0057] In the embodiment, the first gripper 441 and the second gripper 442 are provided with a structure design that fits the motor housing, and can stably clamp the motor for transfer. The first driving member drives the first gripper 441 and the second gripper 442 to move towards or away from each other, which is a conventional setting scheme in a mechanical hand structure and will not be described here.

[0058] Referring to Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, the discharging device 50 includes a discharging conveying assembly 51, a turnover assembly 52, and a material blocking assembly 53. The discharging conveying assembly 51 includes a conveying belt 511 that interfaces with each positioning assembly 30 on one side of the positioning assembly 30, and is used for conveying and discharging the tested motor. The turnover assembly 52 is provided between the conveying belt 511 and the positioning assembly 30, and includes a turnover motor 521 and a turnover rod 522 connected with the turnover motor 521. After the turnover motor 521 drives the turnover rod 522 to turn over, the free end of the turnover rod 522 is located in the avoidance gap to grip the motor, or the free end of the turnover rod 522 is located above the conveying belt 511. The material blocking assembly 53 is movably provided on the other side of the conveying belt 511 and interfaces with the turnover assembly 52, and is used for cooperating with the turnover assembly 52 to realize the falling of the motor onto the conveying belt 511 when the free end is located above the conveying belt 511.

[0059] In the embodiment, the reasonable position arrangement among the conveying belt 511, the positioning assembly 30, the turnover assembly 52 and the material blocking assembly 53 is based on the fact that the free end of the turnover rod 522 is conveniently moved back and forth between the positioning assembly 30 and the conveying belt 511, and the material blocking assembly 53 cooperates with the turnover assembly 52 to realize the discharging of the motor.

[0060] In the application, the conveying belt 511 in each discharging device 50 can be separately arranged to independently convey and discharge the motors that have completed the test in each test device 20. In a preferred embodiment, the conveying belts 511 in each discharging device 50 share the same conveying belt 511 (discharging conveying assembly 51), and the motors that have completed the test can be dropped onto the conveying belt 511 under the cooperation of the corresponding turnover assembly 52 and the material blocking assembly 53.

[0061] Referring to Figure 5 In some embodiments, a discharging guide 512 is arranged at the discharging end of the conveying belt 511, and the discharging guide 512 is arranged obliquely. The discharging guide 512 is formed with a discharging chute 513, one end of the discharging chute 513 is connected to the discharging end of the conveying belt 511, and the motor conveyed by the conveying belt 511 enters the discharging guide 512 and slides along the discharging chute 513 under the action of its own gravity.

[0062] Referring to Figure 6 In some embodiments, the free end of the turnover rod 522 is provided with a clamping groove 523 for clamping the motor, and a magnetic attraction member 524 is arranged on the turnover rod 522 corresponding to the clamping groove 523.

[0063] In the embodiment, the motor is fixed on the turnover rod 522 based on the magnetic force between the motor and the magnetic attraction member 524, so as to move with the turnover rod 522. It can be understood that before the motor is placed on the positioning assembly 30, the free end of the turnover rod 522 needs to be driven by the turnover motor 521 to be located in the avoidance gap formed in the positioning assembly 30, and when it is located in the avoidance gap, the clamping groove 523 is arranged upwardly, and then after the motor is installed, the motor can enter the clamping groove 523 and be fixed by the magnetic attraction member 524.

[0064] One way to fix the motor on the turnover rod 522 is that when the motor is placed on the positioning assembly 30, it can be embedded in the clamping groove 523 and fixed by the magnetic attraction member 524. The magnetic attraction member 524 is arranged side by side on the turnover rod 522, so as to increase the magnetic attraction fixing force on the motor. The magnetic attraction member 524 can be a strong magnet.

[0065] Referring to Figure 6As shown, in some embodiments, the turnover assembly 52 further comprises a vertical driving mechanism 525, and the turnover motor 521 is arranged on the vertical driving mechanism 525 to move in the vertical direction under the driving of the vertical driving mechanism 525.

[0066] In the present embodiment, when the turnover motor 521 is arranged on the vertical driving mechanism 525, the height of the turnover rod 522 can be changed because the turnover motor 521 can be driven to move in the vertical direction. In this case, one way to fix the motor is that when the motor is placed on the positioning assembly 30, there is a gap between the bottom of the slot of the clamping groove 523 on the turnover rod 522 and the motor, and the motor is not fixed in the clamping groove 523. After the test of the motor is completed, the turnover rod 522 can be moved upward by the vertical driving mechanism 525 to magnetically attract and fix the motor in the clamping groove 523. This way of fixing the motor after the test of the motor is completed can prevent the turnover assembly 52 from being damaged by the pressing process in the test of the motor.

[0067] Referring to Figure 2 As shown, in some embodiments, the material blocking assembly 53 comprises a second driving member 531 and a material blocking plate 532; the material blocking plate 532 is connected to the second driving member 531; the material blocking plate 532 is provided with a clamping groove 533 at one end close to the conveying belt 511; and when the free end of the turnover rod 522 is located above the conveying belt 511, the second driving member 531 can drive the material blocking plate 532 to move towards the turnover rod 522, so that the turnover rod 522 is clamped into the clamping groove 533, and the material blocking plate 532 is clamped above the motor.

[0068] In the present embodiment, the material blocking plate 532 is connected with a guide slide rail 535 through a sliding block 534, and the second driving member 531 drives the sliding block 534 to move to drive the material blocking plate 532 to move along the guide slide rail 535. This can make the cooperation between the material blocking plate 532 and the turnover rod 522 more accurate.

[0069] The process of supplying the motor to the conveying belt 511 based on the cooperation between the material blocking assembly 53 and the turnover rod 522 is as follows: the turnover rod 522 is turned over under the drive of the turnover motor 521, the free end of the turnover rod 522 is located above the conveying belt 511, at this time, the orientation of the clamping groove 523 is downwardly arranged, and the motor will not fall off the turnover rod 522 in the process of turning over due to the suction force of the magnetic suction member 524. After the turnover rod 522 is turned over in place, the second driving member 531 drives the material blocking plate 532 to move towards the turnover rod 522, so that the turnover rod 522 is clamped in the clamping opening 533, and the material blocking plate 532 is clamped above the motor. Then, the turnover motor 521 drives the turnover rod 522 to perform a recovery action, and the motor is prevented from following the movement of the turnover rod 522 due to the limiting of the material blocking plate 532, and the motor falls off the turnover rod 522 and falls onto the conveying belt 511 below, and is conveyed along the conveying belt 511.

[0070] In addition, a sensing detection module can be arranged on the side of the conveying belt 511 to detect whether the motor is clamped on the turnover rod 522, and then drive the material blocking assembly 53 to act. The sensing detection module can be an infrared grating sensor arranged in a diagonal opposite state, which has the effect of large detection area and high accuracy. When the free end of the turnover rod 522 is located above the conveying belt 511, the motor is relatively close to the conveying belt 511, so that damage to the motor during falling can be prevented.

[0071] Referring to Figure 1 As shown in the drawings, in some embodiments, the discharging device 50 further comprises a defective product collecting assembly 54, which comprises a defective product guide 541 and a defective product collecting box 542. The defective product guide 541 is arranged obliquely, and a defective product chute is formed on the defective product guide 541. The inlet port of the defective product chute is arranged in abutment with the movement path of the feeding device 40. The defective product collecting box 542 is arranged below the defective product guide 541 and is used to collect the defective motors flowing into the defective product guide 541.

[0072] In this embodiment, after testing by the testing device 20, there will inevitably be defective products that do not meet the testing requirements. At this time, the defective product collecting assembly 54 can be used to collect these defective products. When the inlet port of the defective product chute is arranged in abutment with the feeding device 40, the motor that is defective after testing can be transferred to the defective product assembly for collection by the feeding device 40 again.

[0073] Referring to Figure 1 As shown in the drawings, in some embodiments, each testing device 20 is correspondingly provided with one defective product collecting assembly 54, so as to reduce the action process of the feeding device 40 and improve the production efficiency.

[0074] In summary, the application provides a motor load test device 100, which can improve the load test efficiency of the motor.

[0075] The above only describes some or preferred embodiments of the application, and neither the text nor the drawings can limit the scope of protection of the application. Any equivalent structural transformation based on the content of the specification and drawings, or direct / indirect application in other related technical fields is included in the scope of protection of the application.
