Description

Technical Field

[0001] The invention relates to the technical field of automatic detection, and in particular to a controller automatic detection device. Background Art

[0002] The controller is the core part of the control system. Its main function is to generate control signals according to a certain control strategy based on the given input signal and the system's feedback signal, so that the system's output can track the input signal or remain in the desired state. The controller generally needs to perform product testing during the production process.

[0003] In the prior art, the controller inspection generally includes appearance inspection and signal inspection. Appearance inspection is to check the physical appearance of the controller. For example, the housing, internal electronic components, and connection ports; for signal inspection, for digital input and output, the output pin (port) is connected to a suitable load device, such as an indicator light, a relay, etc. The controller sends an output signal instruction, and observes whether the load device responds correctly to determine whether there is a problem with the controller.

[0004] In the prior art, the input / output (I / O) ports, communication ports and power interfaces on the controller circuit board are inspected to determine whether they are damaged. In the prior art, the inspection is generally performed manually or by machine. For manual inspection, a handheld inspection device is required to inspect the ports on the controller circuit board in sequence, which is inefficient. During machine inspection, the inspection is performed by connecting the inspection terminal on the inspection device to the port on the controller circuit board. Since the inspection terminal on the inspection device is fixed on the drive device in the prior art, the controller circuit board is generally transported to the vicinity of the inspection device during inspection, and after it is in place, it is transferred to the position corresponding to the inspection terminal again. After that, it is driven by the drive device to move to the port on the controller circuit board to complete the inspection of the controller circuit board. In this process, multiple drive devices are required to start and stop together, and highly automated equipment is required, which increases the cost investment of automatic inspection of the controller. In addition, the subsequent use of the equipment will have a large energy demand, further increasing the cost of automatic inspection of the controller. Summary of the invention

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below with reference to the accompanying drawings.

[0036] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 As shown, a controller automatic detection device includes a device base 2, an arch frame 1 is provided on the device base 2, a driving mechanism 21 is provided on the device base 2, a detection mechanism 41 is provided in the arch frame 1, a transmission member 31 is provided in the detection mechanism 41, the driving mechanism 21 drives the transmission member 31 to move up and down, and the driving mechanism 21 drives the detection mechanism 41 to move left and right through the transmission member 31, circuit board conveying frames 51 are provided on both sides of the arch frame 1, and a limiting mechanism 61 is provided on the circuit board conveying frame 51;

[0037] The equipment base 2 is supported by the present invention, and a control module, a toolbox, etc. can be arranged inside. The driving mechanism 21 can drive the detection mechanism 41 to move left and right and the two circuit board conveying racks 51 to move up and down alternately through the transmission member 31. The arch frame 1 is supported by the working area of ​​the present invention. The detection mechanism 41 can detect the controller circuit board port, and the circuit board conveying rack 51 can transfer the controller circuit board to the position of the detection mechanism 41. The limiting mechanism 61 can limit the position of the controller circuit board on the circuit board conveying rack 51.

[0038] Combined with Figure 2 , Attachment Figure 4 , Attachment Figure 5 As shown, the left and right ends of the arch frame 1 are provided with side blocks 6 located on both sides of the operation slot 3, and the side blocks 6 are provided with a conveying structure 7. The arch frame 1 is provided with a plurality of detection support frames 4 located below the operation slot 3, and the circuit board brackets 519 are arranged alternately with the detection support frames 4.

[0039] The conveying structure 7 can be driven by a driving device to achieve the function of conveying the controller circuit board. The circuit board bracket 519 and the detection support frame 4 are staggered to avoid contact with the detection support frame 4 during the downward movement of the circuit board bracket 519.

[0040] Combined with Figure 4 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 As shown, the driving mechanism 21 includes a rotating shaft 211 rotatably arranged in the device base 2, one end of the rotating shaft 211 passes through the device base 2 and a cam member 213 is arranged at the end, and two track grooves 214 are arranged on the arc-shaped end surface of the cam member 213. The two track grooves 214 are in a cross state when they are located in the base circle profile, and in a parallel state when they are located in the working profile;

[0041] The other end of the rotating shaft 211 passes through the device base 2 and is provided with a worm gear 212 at the end. The worm gear 212 is meshed with a worm located on the device base 2, and the worm gear 212 is driven to rotate by the worm gear.

[0042] The arch frame 1 is provided with an operation slot 3, the detection mechanism 41 includes a detection frame 411 slidably arranged in the operation slot 3, the transmission member 31 includes a transmission rod 311 passing through the detection frame 411 and slidably connected to the detection frame 411, a rotating base 312 is rotatably provided at the bottom of the transmission rod 311, a bottom block 313 is provided at the bottom of the rotating base 312, a roller 314 rolling in the track slot 214 is provided inside the bottom block 313, and a guide block 315 slidably connected to the track slot 214 is rotatably provided outside;

[0043] The transmission rod 311 is connected to a spring 316 between the rotating base 312 and the detection frame 411, and a top block 317 is provided on the top of the detection frame 411.

[0044] Start the driving device on the worm, and the worm can drive the worm wheel 212 to rotate. The worm wheel 212 drives the cam member 213 to rotate through the rotating shaft 211. At this time, the cam member 213 can drive the transmission member 31 to move back and forth up and down and left and right. When the roller 314 is transferred from the working contour to the base circle contour, the roller 314 can move from the track groove 214 in a parallel state on one side through the track groove 214 in a cross state to the track groove 214 in a parallel state on the other side. The direction can be limited by the sliding direction of the guide block 315 in the track groove 214 to prevent the roller 314 from deviating from the predetermined track.

[0045] When the roller 314 moves on the track groove 214 in a parallel state on one side, the lateral position of the transmission member 31 remains unchanged, that is, the detection mechanism 41 has moved to one side and started to work, and the transmission rod 311 moves upward at the same time. During the process, the spring 1 316 is compressed, and the transmission rod 311 pushes the circuit board conveying rack 51 on the other side upward. Before this, the circuit board conveying rack 51 on the other side has completed the auxiliary detection of the controller circuit board. The upward movement of the circuit board conveying rack 51 can drive the controller circuit board to move up to the initial state, and start the limiting mechanism 61 to cancel the limit of the controller circuit board, so that the detected circuit board is out of contact with the circuit board conveying rack 51.

[0046] At the same time, the circuit board conveying rack 51 on one side is in the state of being moved down and in place, and the limiting mechanism 61 is limiting the circuit board. When the detection mechanism 41 moves to one side and is in place, the circuit board detection work begins;

[0047] When the roller 314 moves to the top of the working contour, the circuit board conveying rack 51 moves up to its position and detaches from the circuit board after detection and continues to receive the subsequent circuit boards. After limiting, when the roller 314 continues to move from the top of the working contour, the circuit board conveying rack 51 moves down. When the roller 314 moves from the working contour to the base circle contour, the circuit board conveying rack 51 moves down to its position and the detection mechanism 41 moves horizontally to its position and can detect the circuit board.

[0048] In order to allow the circuit board conveying rack 51 to stay at the top for a certain period of time after moving up to the position, the track radius of the track groove 214 at the top of the working profile can be made the same as the rotation radius of the top of the working profile.

[0049] Combined with Fig.10 , Attachment Fig.11 , Attachment Fig.12As shown, grooves 412 are provided at both ends of the detection frame 411, and a detection assembly 413 is provided in the groove 412. The detection assembly 413 includes a plurality of detection members 414 slidably connected to the grooves 412. The bottoms of the plurality of detection members 414 are connected by a telescopic transmission assembly 423, and the inside is penetrated by a bidirectional screw rod 424. The detection members 414 at both ends are threadedly connected to the bidirectional screw rod 424, and the detection members 414 and the bidirectional screw rod 424 in the middle are in a non-contact state. A gear groove 425 is provided at the side end of the detection frame 411, and the bidirectional screw rod 424 passes through the detection frame 411 and a driven gear 426 located in the gear groove 425 is provided at the end thereof. A transmission gear 427 meshing with the driven gear 426 is provided in the gear groove 425, and two transmission gears 427 are meshed with a driving gear 428 located in the gear groove 425, and an adjustment block 429 is provided on the driving gear 428.

[0050] The detection member 414 includes a detection box 415 passed through by a bidirectional screw 424, a bidirectional screw 416 is arranged in the detection box 415, a bevel gear 1 417 is arranged at the center of the bidirectional screw 416, an adjustment terminal 420 is rotatably arranged on the detection box 415, a shaft 419 passing through the detection box 415 is arranged at the bottom of the adjustment terminal 420, a bevel gear 2 418 meshing with the bevel gear 1 417 is arranged at the bottom of the shaft 419, both ends of the bidirectional screw 416 are threadedly sleeved with a connecting member 421, and the end of the connecting member 421 is provided with a detection terminal 422 fixed by a bolt;

[0051] When the detection frame 411 moves into position, the internal detection terminal 422 can contact the circuit board port and perform detection work;

[0052] After the detection frame 411 is moved horizontally to a position, the circuit board port can be detected through the detection terminal 422. A detection device such as a load and a signal transmission module can be arranged in the detection box 415. When the detection terminal 422 contacts the circuit board port, the signal transmission module transmits the data in the form of an electrical signal to the control module to determine whether there is a problem with the circuit board.

[0053] When it is necessary to detect the circuit boards in different controllers, the active gear 428 can be directly adjusted. The active gear 428 drives the two transmission gears 427 to rotate, and the transmission gear 427 drives the driven gear 426. The driven gear 426 drives the bidirectional screw 424 to rotate, and the bidirectional screw 424 drives the detection members 414 at both ends to move, that is, all the detection members 414 on the inner side are driven by the telescopic transmission assembly 423 to achieve the same distance between all the detection members 414. When it is necessary to adjust the distance between the two detection ends 422 in a single detection member 414, the adjustment end 420 is manually rotated, and the adjustment end 420 drives the bevel gear 2 418 to rotate through the shaft 419, and the bevel gear 2 418 drives the bidirectional screw 416 to rotate through the bevel gear 1 417. The rotation of the bidirectional screw 416 can drive the distance between the two connecting members 421 to change.

[0054] When the detection terminal 422 needs to be replaced to adapt to a different port (such as a pin port) of the circuit board, the original detection terminal 422 can be directly removed by unscrewing the bolts and replaced with the corresponding detection terminal 422.

[0055] Combined with Figure 5 , Attachment Figure 8 As shown, the two circuit board conveying racks 51 each include a push rod 511 that slides through the top of the arch frame 1, and the transmission member 31 drives the two circuit board conveying racks 51 to move up and down alternately by alternately pushing the push rods 511 on the two circuit board conveying racks 51;

[0056] The circuit board conveying frame 51 comprises a U-shaped plate 513 located on a top rod 511, a limiting rod 8 passing through the U-shaped plate 513 and slidably connected to the U-shaped plate 513 is provided on the arch frame 1, a cross bar 514 is provided at the end of the U-shaped plate 513, a connecting rod 517 is provided at the bottom of the cross bar 514, a bottom plate 518 is provided on the connecting rod 517, a plurality of circuit board brackets 519 are provided on the end surface of the bottom plate 518 close to the limiting rod 8, a cover frame 520 is provided on the circuit board bracket 519 and the bottom plate 518, a slot 521 is provided on the cover frame 520, a limiting mechanism 61 is slidably provided in the slot 521;

[0057] The arch frame 1 is provided with side end plates 5 located on both sides of the circuit board bracket 519, and both ends of the cross bar 514 are provided with side plates 515, and the bottom of the side plate 515 is provided with a limit plate 516 located between the side end plate 5 and the conveying structure 7;

[0058] After the circuit board conveying rack 51 moves up to its position, the limiting mechanism 61 is started to separate the circuit board from the circuit board bracket 519. A driving device for driving the circuit board bracket 519 to rotate can be set on the bottom plate 518. The driving device can be started only after the circuit board bracket 519 is at the top. The circuit board bracket 519 rotates to separate the detected circuit board and receive the subsequent undetected circuit board. Before receiving, the limiting mechanism 61 is started to limit, and the circuit board stops when it moves to the position of the limiting mechanism 61.

[0059] When the circuit board conveying rack 51 moves down to the detection support rack 4, the circuit board bracket 519 and the detection support rack 4 are arranged in a staggered manner. At this time, the circuit board can be transferred from the circuit board conveying rack 51 to the detection support rack 4, and the circuit board bracket 519 is located below the detection support rack 4. When the circuit board conveying rack 51 continues to move down, the cover frame 520 can move from being located above the circuit board to contacting with the circuit board and pressing the circuit board to prevent the instability of the circuit board from affecting the detection;

[0060] When the circuit board conveying rack 51 moves downward, the cross bar 514 drives the limiting plate 516 to move downward through the side plate 515. Since the limiting plate 516 is located between the side end plate 5 and the conveying structure 7, the limiting plate 516 can limit the circuit board on the conveying structure 7 at this time.

[0061] Combined with Figure 8 , Attachment Fig. 9 As shown, the limiting mechanism 61 includes a slider 611 slidably arranged in the slot 521, a slide rod 612 slides through the slider 611, and end blocks 613 are provided at both ends. An elastic block 614 is provided on one end block 613, and a plurality of fixing rods 615 are provided on the other end block 613. A sliding plate 616 is slidably sleeved on the outside of the fixing rods 615, and a limiting block 617 is provided on the top. A return spring 618 located between the limiting block 617 and the sliding plate 616 is connected to the outer surface of the fixing rod 615. An electric telescopic rod 619 is fixed in the sliding plate 616. The top of the electric telescopic rod 619 is connected to the top of the slide rod 612 by a connecting component 620. The slide rod 612 passes through the slider 611 and a baffle 621 is provided at the bottom.

[0062] The bottom of the top rod 511 is provided with a stopper 512 in contact with the top block 317, and the outer cover of the top rod 511 is connected with a spring 2 522 located between the stopper 512 and the arch frame 1;

[0063] When the circuit board is located on the circuit board bracket 519 and is limited, the electric telescopic rod 619 is started to retract, and the electric telescopic rod 619 drives the sliding rod 612 to move downward through the connecting component 620, and the sliding rod 612 drives the baffle 621 to move downward to the position of the circuit board bracket 519. When the circuit board is transported from the conveying structure 7 to the circuit board bracket 519, it cannot move further under the action of the baffle 621. When the circuit board bracket 519 moves down to the position of the detection support frame 4, the baffle 621 will have a contact with the detection support frame 4. When the detection support frame 4 contacts, when the baffle 621 contacts the detection support frame 4, the baffle 621 will move up relative to the slider 611 under the action of the detection support frame 4. Since the electric telescopic rod 619 has no connection with the end block 613, the baffle 621 will drive the electric telescopic rod 619 to move up as a whole through the slide rod 612. At this time, the reset spring 618 is compressed. When the circuit board bracket 519 moves up, the baffle 621 returns to the limited state under the reset and rebound action of the reset spring 618.

[0064] Specific implementation method: The present invention provides a controller automatic detection device. When using the present invention to detect the controller circuit board:

[0065] The driving mechanism 21 is started to rotate the cam member 213, and the cam member 213 drives the transmission member 31 to move reciprocatingly up, down, left, and right. When the transmission member 31 moves to one side, it drives the detection mechanism 41 to move to one side and detect the circuit boards on the circuit board conveying rack 51 on the same side. When the transmission member 31 moves upward on one side, it drives the circuit board conveying rack 51 on the other side to move upward to transfer the detected circuit boards and receive the undetected circuit boards. After the circuit board conveying rack 51 on the other side moves downward, when the transmission member 31 moves to the other side, it drives the detection mechanism 41 to move to the other side and detect the circuit boards on the circuit board conveying rack 51 on the same side.

[0066] When it is necessary to detect the circuit boards in different controllers, the active gear 428 can be adjusted to drive the change of the spacing between all the detection parts 414. When it is necessary to adjust the distance between the two detection ends 422 in a single detection part 414, the adjustment end 420 can be manually rotated.

[0067] The limiting mechanism 61 can be started to limit the circuit board, and the circuit board stops when it moves to the position of the limiting mechanism 61.

[0068] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto.
