Description

Technical Field

[0001] The invention relates to the technical field of blade processing, and in particular to a blade screening device. Background Art

[0002] The vane of the vane pump is an important part of the pump body. During the production process of the vane, we need to process the vane to improve the strength of the workpiece. The size and shape accuracy of the blade edge are the focus of the inspection during the machining accuracy inspection.

[0003] The vane pump has a small blade size, which is suitable for batch processing in actual processing. There are usually three situations for blades that have been processed in batches: 1. Both sides of the blade are processed; 2. Only one side of the blade is processed; 3. Both sides of the blade are not processed. The blades that have been processed in batches will directly enter the next process.

[0004] Due to the lack of screening process in the blade processing, the unprocessed blades will immediately enter the next process, making it difficult to ensure that the processed blades meet the processing requirements of the next process. Summary of the invention

[0005] The invention discloses a blade screening device to achieve batch screening of blades to meet subsequent processing requirements.

[0006] In order to achieve the above object, the technical solution of the present invention is:

[0007] A blade screening device comprises a power mechanism, a material channel, a detection mechanism, an exclusion mechanism and a conveying mechanism. The material channel is connected to the conveying mechanism, the power mechanism can move the blades along the material channel, the detection mechanism can detect whether the edges of the blades on the material channel have been processed, and when it is detected that the edges of the blades have not been processed, the exclusion mechanism can cause the blades to leave the material channel.

[0008] Furthermore, the power mechanism is a vibration plate, the material channel is connected to the material outlet of the vibration plate, and under the action of the vibration plate, the blade can move along the length direction of the material channel, and the material channel is gradually inclined along the movement direction of the blade, so that the blade deflects around one side edge;

[0009] A rib is provided on a lower side of the material channel, and the blade gradually slides toward the rib during movement along the material channel, so that the edge of the blade abuts against the rib.

[0010] Further, the detection mechanism includes a laser sensor, which can emit laser light to the edge of the blade and detect the laser light reflected by the edge of the blade;

[0011] The exclusion mechanism is arranged above the material channel. The exclusion mechanism is provided with air blowing holes facing the edge of the blade, and the air blowing holes are communicated with a high-pressure air source.

[0012] Further, the conveying mechanism includes a feeding mechanism, a conveying mechanism and a conveying channel. The feeding mechanism has a feeding channel. The screening mechanism includes a material channel. The blades sequentially enter the interior of the conveying channel through the material channel and the feeding channel. The conveying mechanism can push the blades in the conveying channel to move along the length direction of the conveying channel.

[0013] Further, rollers are arranged at the connection of the material channel and the feeding channel. When the blades enter the feeding channel horizontally from the material channel, the lower side of the blades abuts against the rollers, and the moving direction is changed to downward movement.

[0014] Further, the conveying mechanism further includes a first cylinder. The axis direction of the piston rod of the first cylinder coincides with the length direction of the conveying channel. The piston rod of the hydraulic rod extends into the interior of the conveying channel. The piston rod of the first cylinder pushes the blades to move. Preferably, the first cylinder is selected from other linear motion devices such as a hydraulic cylinder or a servo electric push rod.

[0015] Further, the conveying mechanism further includes a mounting seat, a push rod and a first spring. The mounting seat is fixedly connected to the piston rod of the first cylinder. One end of the push rod extends into the conveying channel, and the other end extends into the interior of the mounting seat and is connected to the mounting seat through the first spring.

[0016] Further, a first elastic clip is arranged at the feeding end of the conveying channel. An interval is formed between the first elastic clip and the side wall of the conveying channel. When the blade moves to this interval, the first elastic clip can clamp the blade.

[0017] And / or a second elastic clip is arranged at the discharging end of the conveying channel. An interval is formed between the second elastic clip and the side wall of the conveying channel. When the blade moves to this interval, the second elastic clip can clamp the blade.

[0018] Further, a width measuring sensor is arranged outside the feeding mechanism. The feeding mechanism is provided with a width measuring sensor hole communicated with the feeding channel. The end of the width measuring sensor extends into the feeding channel from the width measuring sensor hole, and the end of the width measuring sensor abuts against the edge of the blade. Preferably, the width measuring sensor is selected from a probe.

[0019] Further, a blanking detection device for detecting whether there are blades inside the conveying channel is further arranged outside the feeding mechanism.

[0020] The beneficial effects of a blade screening device disclosed by the present invention:

[0021] A power mechanism is used to make the blades move along the material channel to realize the transmission of the blades. While the blades are being transmitted, a detection mechanism is used to detect whether the edge of the blades on the material channel has been processed. When it is detected that the edge of the blades has not been processed, the exclusion mechanism does not work and the blades continue to move along the material channel. When it is detected that the edge of the blades has been processed, the exclusion mechanism causes the blades to leave the material channel and re-transmit and detect the blades that have left the material channel through the power mechanism. The above operation is repeated many times to realize batch screening of blades, which is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will combine the accompanying Figures 1-5 drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are 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 belong to the scope of protection of the present invention.

[0030] Refer to Figure 1 , a blade screening device that can screen out the blades 30 to be processed, including a power mechanism 1, a material path 2, a detection mechanism, an exclusion mechanism 4 and a conveying mechanism 5.

[0031] Refer to Figure 1 , the power mechanism 1 is a vibrating disk, the vibrating disk has a feeding tray 11 and a guide plate 12. Among them, the guide plate 12 is spirally distributed with the feeding tray 11 as the center, and the power mechanism 1 can make the blade 30 move along the material path 2. The blades 30 to be screened are put into the inside of the feeding tray 11. Under the vibration of the vibrating disk, the blades 30 can move along the length direction of the guide plate 12 and the blades 30 can be distributed in a single row during the movement.

[0032] Combined with Figure 1 and Figure 2, the material channel 2 is arranged at the outlet of the material guiding plate 12. The material channel 2 and the material guiding plate 12 are integrally formed, and the whole formed by the material channel 2 and the material guiding plate 12 is still spiral. The width of the material channel 2 gradually decreases from the side close to the material guiding plate 12 to the side far from the material guiding plate 12 until the width of the material channel 2 is equal to the width of the blade 30. When the width of the material channel 2 is equal to the width of the blade 30, the material channel 2 begins to gradually incline along the movement direction of the blade 30. The higher side of the material channel 2 is located on the side close to the center of the vibrating disk, and a retaining edge 21 that can prevent the blade 30 from detaching from the material channel 2 under the vibration action is integrally formed on the lower side of the material channel 2. During the movement of the blade 30 along the material channel 2, under the action of the inclined surface of the material channel 2, the blade 30 gradually slides towards the retaining edge 21, and the blade 30 deflects with its side far from the center of the vibrating disk as the center until the blade 30 is tangent to the inclined surface of the material channel 2. At this time, the edge of the blade 30 abuts against the retaining edge 21.

[0033] Combined with Figure 1 and Figure 2 , there are multiple material channels 2, and the multiple material channels 2 are arranged side by side. The number of the material channels 2 in this application is not limited. Taking two material channels 2 as an example in this embodiment, the two material channels 2 are arranged side by side along the width direction of the material guiding plate 12, and a partition plate 22 is arranged between the two material channels 2. The height of the partition plate 22 is greater than the thickness of a single blade 30 and less than the sum of the thicknesses of three blades 30. When multiple blades 30 reach the connection part of the material guiding plate 12 and the material channel 2 at the same time, the multiple blades 30 are likely to be stacked on top of each other. At this time, the blade 30 located on the upper layer crosses the partition plate 22 under the vibration of the vibrating disk and enters the adjacent material channel 2, and the blade 30 located on the lower layer enters the material channel 2.

[0034] Combined with Figure 3 and Figure 4 , the detection mechanism is preferably the laser sensor 3. The laser sensor 3 is arranged above the material channel 2. When the blade 30 moves along the material channel 2 to the lower part of the laser sensor 3, the laser sensor 3 can emit laser to the edge of the blade 30 and detect the laser reflected by the edge of the blade 30. By analyzing the data of the reflected laser, it is further judged whether the edge of the blade 30 irradiated by the laser is processed. When it is detected that the edge of the blade 30 is not processed, the blade 30 can continue to move along the material channel 2. When it is detected that the edge of the blade 30 has been processed, the exclusion mechanism 4 can make the blade 30 detach from the material channel 2.

[0035] Combined with Figure 3 and Figure 4, the exclusion mechanism 4 is arranged above the material channel 2. The exclusion mechanism 4 includes an air duct 41 having a blow hole 411 and a high-pressure air source. The air outlet direction of the blow hole 411 is inclined, so that the air outlet direction of the blow hole 411 covers the edge of the blade 30. The air duct 41 is communicated with the high-pressure air source. When it is detected that the edge of the blade 30 has been processed, the high-pressure air source can supply high-pressure gas to the air duct 41, and the blow hole 411 blows air towards the edge of the blade 30, thereby blowing the blade 30 off the material channel 2, so as to blow the processed blade 30 off the material channel 2 and retain the unprocessed blade 30 on the material channel 2 for subsequent processing.

[0036] Combined with Figure 3 and Figure 4 , taking each detection mechanism and the exclusion mechanism 4 as a group, a group of detection mechanism and the exclusion mechanism 4 are correspondingly arranged on each material channel 2. The detection mechanism and the exclusion mechanism 4 located on the same material channel 2 are arranged side by side along the width direction of the material channel 2, and the adjacent groups of detection mechanisms and exclusion mechanisms 4 are connected in series. The distance between the detection mechanism and the exclusion mechanism 4 in the same group and the edge of the blade 30 can be adjusted synchronously.

[0037] Combined with Figure 3 and Figure 4 , a horizontally arranged connecting rod 6 is fixedly provided between the detection mechanism and the exclusion mechanism 4 in the same group. One end of the connecting rod 6 extends to the outside of the vibrating disk, and a lifting mechanism for adjusting the height of the connecting rod 6 is arranged outside the vibrating disk.

[0038] Combined with Figure 3 and Figure 4 , the lifting mechanism includes a support 71, a lifting rod 72 and a lifting slider 73. The lifting rod 72 is vertically arranged on the support 71. A through hole is formed in the lifting slider 73, and the lifting rod 72 passes through the through hole and is slidably connected with the lifting slider 73. A handle 74 with a bolt is arranged on the lifting slider 73, and the bolt of the handle is inserted into the through hole from the side of the lifting slider 73 and presses against the lifting rod 72.

[0039] Combined with Figure 3 and Figure 4 , a horizontally arranged sliding rod 75 is also fixedly provided on the lifting slider 73. A sliding block 76 with an upper end opening is sleeved on the sliding rod 75. The distance between the opening ends of the sliding block 76 can be adjusted by adjusting the handle 77, and the adjusting handle 77 is threadedly connected with the sliding block 76. The connecting rod 6 is fixedly connected with the sliding block 76. As the opening of the sliding block 76 decreases, the sliding block 76 can clamp the sliding rod 75, so that the relative position of the sliding block 76 and the sliding rod 75 is fixed.

[0040] Combined with Figure 1 and Figure 5, the conveying mechanism 5 includes a feeding mechanism 51, a conveying mechanism 52, and a conveying channel 53. The feeding mechanism 51 has a vertically arranged feeding channel 511. The number of the feeding channels 511 is equal to the number of the material channels 2. The feeding channels 511 are communicated with the material channels 2. The blades 30 sequentially enter the inside of the conveying channel 53 through the material channels 2 and the feeding channels 511. A roller 8 is arranged at the communicating part of the feeding channel 511 and the material channel 2. When the blade 30 enters the feeding channel 511 from the material channel 2, the lower side edge of the blade 30 contacts the roller 8. Under the action of the roller 8, the moving direction of the blade 30 rotates by 90°. The blades 30 are vertically arranged and stacked up and down inside the feeding channel 511. The conveying channel 53 is horizontally arranged below the feeding channel 511. The entrance of the conveying channel 53 faces upward. The blades 30 located inside the feeding channel 511 can enter the inside of the conveying channel 53 under the action of gravity and are vertically arranged inside the conveying channel 53.

[0041] Combined with Figure 1 and Figure 5 , the conveying mechanism 52 is arranged at the end of the conveying channel 53. The conveying mechanism 52 further includes a first cylinder 521, a mounting seat 522, a push rod 523, and a first spring 524. The central lines of the piston rod of the first cylinder 521, the push rod 523, and the conveying channel 53 are on the same horizontal plane. In this application, the first cylinder 521 can be selected from other linear motion devices such as a hydraulic cylinder or a servo electric push rod 523. In this embodiment, a hydraulic cylinder is taken as an example. A cylinder extended position sensor 401 and a cylinder retracted position sensor 402 capable of determining whether the cylinder is in place are installed on the first cylinder 521.

[0042] Combined with Figure 1 and Figure 5 , the mounting seat 522 is arranged outside the conveying channel 53. The mounting seat 522 is fixedly connected to the piston rod of the first cylinder 521. A buffer cavity is opened along the length direction of the mounting seat 522. One end of the push rod 523 extends into the conveying channel 53, and the other end extends into the buffer cavity inside the mounting seat 522. The push rod 523 is arranged in a plate shape. The width of the plate-shaped push rod 523 is smaller than the length of the blade 30. The plate surface of the push rod 523 is flush with the blade 30 located inside the conveying channel 53. The push rod 523 can contact the unprocessed side edge of the blade 30. The first spring 524 is arranged inside the buffer cavity. The push rod 523 is connected to the mounting seat 522 through the first spring 524. The setting of the spring can reduce the cumulative motion error of multiple blades 30.

[0043] Combined with Figure 1 and Figure 5, a first elastic clip 91 is provided at the feeding end of the conveying channel 53. A gap is formed between the first elastic clip 91 and the side wall of the conveying channel 53. When the blade 30 enters the conveying channel 53 through the feeding channel 511, the first cylinder 521 is started. The first cylinder 521 drives the push rod 523 to move through the mounting seat 522, so that the push rod 523 located inside the conveying channel 53 pushes the blade 30 into this gap, and the blade 30 is clamped by the first elastic clip 91, which can prevent the blade 30 from moving excessively. The blades 30 located inside the conveying channel 53 push each other, so that the blade 30 moves along the length direction of the conveying channel 53.

[0044] Combined with Figure 1 and Figure 5 , a second elastic clip 92 is provided at the discharging end of the conveying channel 53. A gap is formed between the second elastic clip 92 and the side wall of the conveying channel 53. When the blade 30 moves to this gap, the second elastic clip 92 can clamp the blade 30, so that the blade 30 is not easily disengaged from the conveying channel 53.

[0045] Combined with Figure 1 and Figure 5 , a width measurement sensor 10 is fixedly provided above the mounting seat 522. In this embodiment, the width measurement sensor 10 is preferably a probe. The width measurement sensor 10 can move synchronously with the mounting seat 522. The feeding mechanism 51 is provided with a width measurement sensor 10 hole communicating with the feeding channel 511. When the push rod 523 pushes the blade 30, the end of the width measurement sensor 10 extends from the width measurement sensor 10 hole. The end of the width measurement sensor 10 abuts against the edge of the blade 30 at the connection of the conveying channel 53 and the feeding channel 511. The width measurement sensor 10 remains stationary under the action of the blade 30. Since the push rod 523 continues to push the blade 30 located in the conveying channel 53 at this time, the mounting seat 522 drives the width measurement sensor 10 seat to continue to move. At this time, the width measurement sensor 10 has a certain amount of shrinkage. The thickness of the blade 30 is calculated and analyzed through the shrinkage amount fed back by the width measurement sensor 10.

[0046] Combined with Figure 1 and Figure 5 , a blanking detection device 20 for detecting whether there is a blade 30 inside the conveying channel 53 is further provided outside the feeding mechanism 51. The blanking detection device 20 is preferably a blanking detection sensor.

[0047] The implementation principle of this application is as follows: Place the blade 30 to be screened on the feeding tray 11. Under the vibration of the vibrating bowl, the blade 30 can move in a single row along the length direction of the guiding plate 12. When the blade 30 moves to the connection between the material channel 2 and the guiding plate 12, the blade 30 horizontally enters the interior of the material channel 2. Since the material channel 2 gradually inclines along the movement direction of the blade 30, the blade 30 inclines synchronously with the material channel 2, causing the blade 30 to deflect from the horizontal state to the vertical state. At this time, one of the sides of the blade 30 to be detected faces upward; when the blade 30 continues to move along the material channel 2 to below the detection mechanism, the laser sensor 3 can emit laser light towards the edge of the blade 30 and detect the laser light reflected by the edge of the blade 30. By analyzing the reflected laser light, it is determined whether the edge of the blade 30 irradiated by the laser has been processed. When it is detected that the edge of the blade 30 has not been processed, the blade 30 can continue to move along the material channel 2. When it is detected that the edge of the blade 30 has been processed, the high-pressure air source can supply high-pressure gas to the air duct 41, and the air blowing holes 411 blow air towards the edge of the blade 30, thereby blowing the blade 30 off the material channel 2. Thus, the processed blade 30 is blown off the material channel 2, and the blown-off blade 30 is placed back on the feeding tray 11. Repeat the above operations. The unprocessed blades 30 remain on the material channel 2 and move along the material channel 2. When the blade 30 moves to the connection between the material channel 2 and the feeding channel 511, the movement direction of the blade 30 rotates 90°, and the blade 30 vertically enters the feeding channel 511 and moves downward under its own gravity until it enters the connection between the feeding channel 511 and the conveying channel 53. The first cylinder 521 drives the push rod 523 to push the blade 30, enabling the blade 30 to move along the conveying channel 53 and enter the next process, thereby completing the screening work of the blade 30.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
