Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and specifically to a detection device for electrical automation equipment. Background Art

[0002] Electrical automation equipment plays a crucial role in industrial production. The accurate detection of its operating state is the core link to ensure the reliability of the equipment and production efficiency. Most of the existing detection technologies adopt the method of cooperating a fixed detection device with a conveyor belt, that is, the device to be detected is conveyed to the detection area through the conveyor belt, and temperature, pressure, vibration and other parameters are collected in real time by a probe.

[0003] However, such methods have significant defects: there is a continuous relative displacement between the detection device and the electrical equipment during the conveying process, resulting in the probe being unable to stably contact the target to be measured, and further causing problems such as data acquisition distortion and a decrease in the monitoring accuracy of dynamic parameters. For this reason, we propose a detection device for electrical automation equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a detection device for electrical automation equipment, and its advantage is that by synchronizing the detector with the device to be detected, it is ensured that the detector and the device to be detected are relatively stationary during the detection process, and the problem that the probe cannot stably contact the target to be measured due to relative displacement when the detection device detects the device to be detected on the conveyor belt is solved.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A detection device for electrical automation equipment, including: a conveyor belt, on the surface of which there are uniformly distributed shielding blocks for pushing the device to be detected to move; a detection component, including a detector and movable frames symmetrically arranged on both sides of the conveyor belt. A detection probe is provided at the bottom of the detector. Fixed plates are fixedly provided on the brackets on both sides of the conveyor belt. The movable frames are slidably connected to the sliding openings of the fixed plates and are fixedly connected to telescopic cylinders fixedly arranged on the brackets on both sides of the conveyor belt through first compression springs. A shielding plate is fixedly provided on the outer side of the bottom of the detector. A shielding frame is provided inside the movable frame. The two sides of the device to be detected are clamped by the shielding plate and the shielding frame so that the detector can move synchronously with the device to be detected; a driving component for driving the detector to move away from the device to be detected after the detection is completed; a limiting component for fixing the position of the movable frame after the detection is completed to ensure that the device that has completed the detection is transported out of the movable frame.

[0006] Preferably, the driving component includes a gear, a rack and a fixed rail. The fixed rail is fixed to the outside of the fixed plate. The fixed rail is arranged above the sliding opening and is fixedly provided with external teeth at the bottom. The external teeth are arranged at one end of the fixed rail away from the feeding end of the conveyor belt. The gear is rotatably connected to the movable frame through a mounting block. The mounting block is slidably arranged in the sliding opening. The rack is fixed to the outside of the detector and meshes with the gear. The rack is slidably connected to the movable frame through a slide rail and a slide groove, and the displacement control of the detector is realized through the meshing of the gear and the external teeth.

[0007] Preferably, the limiting component includes a limiting cylinder, a positioning block and a limiting shaft. The limiting cylinder is fixedly arranged in the movable frame. A piston block with a limiting spring is slidably arranged in the limiting cylinder. A piston rod is slidably arranged on one side of the limiting cylinder close to the conveyor belt. One end of the piston rod is fixed to the piston block, and the other end is fixed to the limiting shaft. The positioning block is arranged in the brackets on both sides of the conveyor belt. A limiting groove matching the limiting shaft is arranged on the outer side of the positioning block. The engagement or separation of the limiting shaft and the limiting groove is realized through the telescopic movement of the piston rod. An auxiliary component for pushing the limiting shaft out of the limiting groove is arranged in the movable frame.

[0008] Preferably, the auxiliary component includes a second compression spring, a fixed cylinder, a sliding frame and a piston plate. The fixed cylinder is fixed in the movable frame. The fixed cylinder is communicated with the limiting cylinder through a fixed air pipe. One end of the fixed air pipe is fixed to the fixed cylinder, and the other end is fixed to the side where the limiting cylinder is connected to the piston rod. The piston plate is slidably arranged in the fixed cylinder. The piston plate is fixedly connected with the sliding frame through a pressing rod fixed thereto. The sliding frame is slidably arranged in the movable frame. One end of the pressing rod away from the piston plate penetrates through the movable frame and is slidably connected with the movable frame. The second compression spring is fixed in the movable frame, and the end not fixed to the movable frame is fixed to the sliding frame. The movement of the sliding frame is used to control the limiting shaft to move out of the limiting groove.

[0009] Preferably, slots are arranged on the outer sides of the brackets on both sides of the conveyor belt. The positioning block is slidably arranged in the slots through a screw rod. The screw rod is driven by a motor. The screw rod is rotatably arranged in the slots. The motor is fixed outside the slots and is used to adjust the lateral position of the positioning block to adapt to different sizes of devices to be detected.

[0010] Preferably, an auxiliary opening is arranged on one side of the slot close to the feeding end of the conveyor belt. An auxiliary plate is fitted in the auxiliary opening. The auxiliary plate is fixed to the positioning block and its surface is in sliding contact with the limiting shaft, and is used to guide the limiting shaft to accurately enter the limiting groove.

[0011] Preferably, a ball is rotatably arranged at one end of the limiting shaft away from the piston rod to reduce the frictional resistance when the limiting shaft contacts the auxiliary plate or the positioning block.

[0012] Preferably, the shielding frame is rotatably arranged inside the sliding frame. The shielding frame can be rotated upward to form a placing opening for the device to be detected to enter between the two movable frames.

[0013] Preferably, auxiliary brackets are fixedly arranged on the outer sides of the brackets on both sides of the conveyor belt and are used to provide auxiliary support for the sliding of the movable frame. The bottom of the movable frame is slidably matched with the inside of the auxiliary brackets.

[0014] Preferably, the first compression spring is sleeved on the telescopic cylinder. One end of it is fixed to the end of the telescopic cylinder, and the other end is fixedly connected with the movable frame. The elastic reset is used to ensure that the detection component automatically returns to its original position after the detection is completed.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. During the process of the conveyor belt driving the device to be detected, the two sides of the device to be detected are clamped by the baffle and the shielding frame so that the detector can move synchronously with the device to be detected, enabling the detector to accurately detect the moving device to be detected and ensuring that the probe of the detector can stably contact the target to be measured.

[0017] 2. The present invention is provided with a structure in which a gear, a rack, and a fixed rail with external teeth cooperate with each other. When the detector starts to move with the device to be detected, the gear slides on the part of the fixed rail without external teeth, and at this time, the detector detects the device to be detected. When the detection is completed, the gear moves to the part of the fixed rail with external teeth. As the detector continues to move, the gear meshes and rotates on the external teeth, thereby driving the rack to move upward, and further driving the entire detector to move away from the device to be detected, facilitating the removal of the detected device.

[0018] 3. When the detector moves away from the device to be detected, the present invention can limit the entire movable frame on the brackets on both sides of the conveyor belt through the limiting component (the limiting shaft is embedded in the limiting groove of the positioning block), preventing the movable frame from moving accidentally, so that the detected device can be smoothly removed from between the movable frames without being blocked by the internal structure of the movable frame (because when the movable frame resets, the gear will roll back on the external teeth, which will drive the detector to move downward). The shielding frame moves together with the sliding frame and the device under the action of the second compression spring. When the device is removed from the movable frame, the second compression spring pushes the sliding frame to squeeze the pressure rod and the piston plate, and uses air pressure to push the piston block to move, thereby moving the limiting shaft out of the limiting groove of the positioning block and releasing the movable frame. The movable frame can smoothly return to the initial position under the action of the first compression spring. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Please refer to Figure 1 - Figure 8 , an electrical automation equipment detection device shown in the figure, including: a conveyor belt 1, on the surface of which uniformly distributed blocking blocks 2 are provided for pushing the equipment to be detected to move; a detection component 3, including a detector 4 and movable frames 5 symmetrically arranged on both sides of the conveyor belt 1, a detection probe 6 is provided at the bottom of the detector 4, fixed plates 7 are fixedly provided on the brackets on both sides of the conveyor belt 1, the movable frames 5 are slidably connected in the sliding openings 8 of the fixed plates 7, and are fixedly connected to the telescopic cylinders 10 fixedly provided on the brackets on both sides of the conveyor belt 1 through the first compression springs 9. A baffle plate 11 is fixedly provided on the outer side of the bottom of the detector 4, and a blocking frame 12 is provided in the movable frame 5. The two sides of the equipment to be detected are clamped by the baffle plate 11 and the blocking frame 12 so that the detector 4 can move synchronously with the equipment to be detected; the first compression spring 9 is sleeved on the telescopic cylinder 10, one end of which is fixed to the end of the telescopic cylinder 10, and the other end is fixedly connected to the movable frame 5, and the detection component 3 is automatically reset through elastic reset after the detection is completed;

[0030] In addition, auxiliary brackets 38 are fixedly arranged on the outer sides of the brackets on both sides of the conveyor belt 1, which are used to provide auxiliary support for the sliding of the movable frame 5. The bottom of the movable frame 5 is slidably matched with the inside of the auxiliary bracket 38. The movable frame 5 slides in the sliding opening 8 under the support of the auxiliary bracket 38, and the movement is more stable and smooth.

[0031] In the specific implementation process, each component of the electrical automation equipment detection device realizes the high-efficiency detection function through coordinated operation. The shielding blocks 2 on the surface of the conveyor belt 1 are evenly distributed. When the device to be detected is placed on the conveyor belt 1, the shielding blocks 2 push the device to move along the conveying direction. At this time, the movable frame 5 in the detection component 3 is embedded in the sliding opening 8 of the fixed plate 7 through a sliding connection, and is fixedly connected with the telescopic cylinder 10 on the bracket through the first compression spring 9 to form an elastic support structure. When the device enters the detection area, the shielding plate 11 at the bottom of the detector 4 and the shielding frame 12 on the inner side of the movable frame 5 act together to clamp both sides of the device, so that the detector 4 and the device move synchronously. During this process, the detection probe 6 remains in stable contact with the surface of the device, avoiding detection errors caused by relative displacement.

[0032] The driving component 13 is used to drive the detector 4 to move away from the device to be detected after the detection is completed; the driving component 13 includes a gear 15, a rack 16 and a fixed rail 17. The fixed rail 17 is fixedly connected to the outside of the fixed plate 7. The fixed rail 17 is arranged above the sliding opening 8 and is fixedly provided with external teeth 18 at the bottom. The external teeth 18 are arranged at one end of the fixed rail 17 away from the feeding end of the conveyor belt 1. The gear 15 is rotatably connected to the movable frame 5 through a mounting block 19. The mounting block 19 is slidably arranged in the sliding opening 8. The rack 16 is fixed to the outside of the detector 4 and meshes with the gear 15. The rack 16 is slidably connected to the movable frame 5 through a slide rail and a slide groove, and the displacement control of the detector 4 is realized through the meshing of the gear 15 and the external teeth 18.

[0033] The driving component 13 controls the displacement of the detector 4 through the meshing relationship between the gear 15 and the fixed rail 17. When the device starts to move, the gear 15 is located in the toothless area of the fixed rail 17. At this time, the gear 15 only slides with the movable frame 5, and the rack 16 meshes with the gear 15 to keep the detector 4 in a horizontal state to complete the dynamic detection. When the detection is completed, the gear 15 moves to the external teeth 18 part of the fixed rail 17. As the conveyor belt 1 continues to run, the gear 15 meshes with the external teeth 18 and rotates, driving the rack 16 to move upward, thereby lifting the detector 4 as a whole and separating it from the device. This action ensures that the detected device can smoothly leave the detection area, avoiding secondary contact or interference between the probe and the device.

[0034] The limiting component 14 is used to fix the position of the movable frame 5 after the detection is completed, ensuring that the equipment that has completed the detection is transported out of the movable frame 5. The limiting component 14 includes a limiting cylinder 20, a positioning block 21 and a limiting shaft 22. The limiting cylinder 20 is fixedly arranged in the movable frame 5. A piston block 23 with a limiting spring is slidably arranged in the limiting cylinder 20. A piston rod 24 is slidably arranged on one side of the limiting cylinder 20 close to the conveyor belt 1. One end of the piston rod 24 is fixed to the piston block 23, and the other end is fixed to the limiting shaft 22. The positioning block 21 is arranged in the brackets on both sides of the conveyor belt 1. A limiting groove 25 matching the limiting shaft 22 is arranged on the outer side of the positioning block 21. The engagement or separation of the limiting shaft 22 and the limiting groove 25 is realized through the expansion and contraction of the piston rod 24. An auxiliary component 26 for pushing the limiting shaft 22 out of the limiting groove 25 is arranged in the movable frame 5.

[0035] Furthermore, the auxiliary component 26 includes a second compression spring 27, a fixed cylinder 28, a sliding frame 29 and a piston plate 30. The fixed cylinder 28 is fixed in the movable frame 5. The fixed cylinder 28 is communicated with the limiting cylinder 20 through a fixed air pipe 31. One end of the fixed air pipe 31 is fixed to the fixed cylinder 28, and the other end is fixed to the side where the limiting cylinder 20 is connected to the piston rod 24. The piston plate 30 is slidably arranged in the fixed cylinder 28. The piston plate 30 is fixedly connected to the sliding frame 29 through a pressure rod 32 fixed thereto. The sliding frame 29 is slidably arranged in the movable frame 5. One end of the pressure rod 32 away from the piston plate 30 penetrates through the movable frame 5 and is slidably connected to the movable frame 5. The second compression spring 27 is fixedly arranged in the movable frame 5, and the end not fixed to the movable frame 5 is fixed to the sliding frame 29. The movement of the sliding frame 29 is used to control the limiting shaft 22 to move out of the limiting groove 25.

[0036] After the detection is completed, the limiting component 14 realizes the fixation and release of the movable frame 5 through pneumatic and mechanical linkage. The piston block 23 in the limiting cylinder 20 is connected to the limiting shaft 22 through the piston rod 24. When the detector 4 is lifted, the movable frame 5 moves to a predetermined position, and the limiting shaft 22 is embedded in the limiting groove 25 of the positioning block 21, locking the movable frame 5 on the bracket to prevent its accidental movement. At this time, the equipment that has completed the detection is transported out between the movable frames 5 under the push of the conveyor belt 1. When the equipment has completely passed, the sliding frame 29 in the auxiliary component 26 moves towards the fixed cylinder 28 under the action of the second compression spring 27, pushing the pressure rod 32 to squeeze the piston plate 30 and compressing the air in the fixed cylinder 28. The air pressure is transmitted to the limiting cylinder 20 through the fixed air pipe 31, pushing the piston block 23 to drive the limiting shaft 22 to withdraw from the limiting groove 25. The movable frame 5 then returns to the initial position under the elastic reset action of the first compression spring 9, preparing for the detection of the next equipment. In the whole process, each component realizes seamless connection through mechanical linkage and elastic reset mechanism, ensuring the detection efficiency and stability.

[0037] It should be noted that the shielding frame 12 is rotatably arranged inside the sliding frame 29. The shielding frame 12 can be rotated upward to form a placement opening for the device to be detected to enter between the two movable frames 5, so that the device to be detected can smoothly enter the detection area, facilitating the shielding plate 11 and the shielding frame 12 to be on both sides of the device to be detected.

[0038] The implementation steps of this technical solution are as follows:

[0039] S1. After the device to be detected is placed on the surface of the conveyor belt 1, the conveyor belt 1 starts to run. The shielding blocks 2 evenly distributed on its surface push the device towards the detection area through physical blocking. The layout of the shielding blocks 2 ensures the stability of the device during transportation, avoiding deviation or tilt. During this process, the device is in the clamping area between the movable frames 5, and the shielding frame 12 and the shielding plate 11 at the bottom of the detector 4 jointly clamp both sides of the device. The movable frames 5 are slidably connected to the fixed plate 7 through the sliding openings 8 and adapt to the thickness of the device under the elastic support of the first compression spring 9, ensuring an appropriate clamping force without damaging the surface of the device. The detection probe 6 at the bottom of the detector 4 is in stable contact with the surface of the device. At the same time, the conveyor belt 1 continues to run, and the movable frames 5 move synchronously with the device, keeping the probe and the device in a relatively static state all the time, thus realizing the dynamic and accurate detection of the moving device;

[0040] S2. During the detection process, the gear 15 moves in the toothless section of the fixed rail 17. When the detection is completed, the movable frame 5 moves with the device to the external tooth 18 section of the fixed rail 17. At this time, the gear 15 connected to the movable frame 5 meshes with the external teeth 18. As the conveyor belt 1 continues to run, the gear 15 rotates and drives the rack 16 to rise vertically, lifting the entire detector 4 away from the surface of the device. This action ensures that the detection probe 6 is completely separated from the device, avoiding secondary contact or interference with the detected device, and at the same time creating space for the device to be transported out of the detection area;

[0041] S3. During the lifting process of the detector 4, the movable frame 5 moves to a preset position, and the piston rod 24 in the limit cylinder 20 pushes the limit shaft 22 to embed into the limit groove 25 of the positioning block 21, fixing the movable frame 5 to the brackets on both sides of the conveyor belt 1. This prevents the movable frame 5 from moving accidentally when the device is transported out, ensuring the continuity of the detection process;

[0042] The device that has completed the detection is smoothly transported out from between the movable frames 5 under the push of the conveyor belt 1, and the shielding frame 12 moves along with the device. During the process of the device passing through, the second compression spring 27 in the auxiliary assembly 26 pushes the sliding frame 29 towards the fixed cylinder 28, and the pressing rod 32 accordingly squeezes the piston plate 30, compressing the air inside the fixed cylinder 28. The compressed air is transmitted to the limiting cylinder 20 through the fixed air pipe 31, pushing the piston block 23 to retract and driving the limiting shaft 22 to gradually withdraw from the limiting groove 25. When the device has completely passed through, the limiting shaft 22 completely withdraws from the limiting groove 25, releasing the locking state of the movable frame 5. Under the elastic reset action of the first compression spring 9, the movable frame 5 smoothly returns to the initial position along the sliding opening 8, preparing for the detection cycle of the next device;

[0043] S4. The conveyor belt 1 continues to run, repeating the above processes of clamping, detecting, separating, locking, and resetting. Through the precise cooperation of each structure, the device realizes the efficient and accurate detection of electrical automation devices, and at the same time is compatible with the dynamic requirements of devices of different sizes.

[0044] Embodiment 2: This embodiment further elaborates on Embodiment 1. As Figure 5 shown, the difference lies in the optimization of the position of the positioning block 21;

[0045] Specifically, on the outer sides of the brackets on both sides of the conveyor belt 1, there are slots 33. The positioning block 21 is slidably arranged in the slots 33 through screws 34. The screws 34 are driven by a motor 35. The screws 34 are rotatably arranged in the slots 33, and the motor 35 is fixed outside the slots 33, used to adjust the lateral position of the positioning block 21 to adapt to devices to be detected of different sizes;

[0046] In addition, on one side of the slot 33 close to the feeding end of the conveyor belt 1, there is an auxiliary opening. An auxiliary plate 36 is fitted in the auxiliary opening. The auxiliary plate 36 is fixed to the positioning block 21, and its surface is in sliding contact with the limiting shaft 22, used to guide the limiting shaft 22 to accurately enter the limiting groove 25;

[0047] By driving the screw 34 to rotate through the motor 35, the positioning block 21 is driven to move outside the conveyor belt 1, and the positioning block 21 is moved to the appropriate external teeth 18, thereby adjusting the moving distance of the gear 15 on the external teeth 18, and further regulating the rising distance of the rack 16 and the detector 4, so as to meet the detection requirements of electrical devices of different sizes.

[0048] Embodiment 3: This embodiment further elaborates on Embodiment 1. As Figure 7 shown, the difference lies in the optimization of the limiting shaft 22;

[0049] Specifically, at one end of the limiting shaft 22 away from the piston rod 24, a ball 37 is rotatably provided to reduce the frictional resistance when the limiting shaft 22 contacts the auxiliary plate 36 or the positioning block 21, ensuring the accuracy and smoothness of the limiting action.
