Example

This embodiment provides a turntable-type detection device for detecting a workpiece 10 with a circular edge. As shown in Figure 4 of the specification, the turntable-type detection device includes a turntable 7 and a liftable guide for the turntable-type detection device. Mechanism, four detection mechanisms 8, cleaning combination mechanism 9 and control mechanism, and the liftable guiding mechanism of the turntable type detection equipment, four detection mechanisms 8 and cleaning combination mechanism 9 are all located around the turntable 7, and on the turntable 7 It has a loading area 71 and an unloading area; among them, the loading area 71 is used to place the workpiece 10 to be detected, and along the rotation direction of the turntable 7, the lifting guide of the turntable type detection equipment is set behind the loading area 71 The mechanism is used to guide and position the workpiece 10 in the feeding area 71, so that the workpiece 10 is in a preset detection area that is convenient for detection; after the lifting and guiding mechanism of the turntable type detection equipment, there are four detection mechanisms 8 If the setting position is set, the workpiece 10 after passing through the lifting and guiding mechanism of the turntable type detection equipment can enter the detection process; it should be noted that the above-mentioned preset detection area is an area that can be completely exposed to the field of view of the four detection mechanisms 8 , that is, the workpiece 10 can be completely exposed within the detectable range of the detection mechanism 8, and the liftable guiding mechanism of the turntable type detection equipment is used to limit the workpiece 10 within the preset detection area to ensure accurate and reliable detection results; In a possible implementation of this specification, the preset detection area can be selected as an annular area near the edge of the turntable 7, and this annular area can fall within the visual range of each detection mechanism 8, then During the rotation of the turntable 7, it can be ensured that the workpiece 10 can be monitored comprehensively and completely during detection, with high accuracy.

Specifically, as shown in the accompanying drawings 1-3 of the specification, the liftable guiding mechanism of the turntable type detection equipment is used to guide the position of a workpiece 10 with a round edge on the turntable 7, so that the workpiece 10 falls into the predetermined position. The detection area is set to ensure the accuracy of the detection results; wherein, as shown in Figure 1, the liftable guiding mechanism of the turntable type detection equipment includes a connecting block 1 and two limit blocks 2, and the limit blocks 2 are set on The lower surface of the connecting block 1 protrudes downward, so that the connecting block 1 plays the role of connecting and fixing the two limiting blocks 2, and also enables the connecting block 1 to drive the two limiting blocks when it moves The blocks 2 move together in the vertical direction; in a possible implementation of this specification, the connecting block 1 and the limiting block 2 can be set as an integrated structure, which further simplifies the structure, speeds up the processing efficiency, reduces assembly steps, and saves processing and configuration costs.

Specifically, the two limiting blocks 2 play a positioning role to limit the position of the workpiece 10. During the guiding process, the workpiece 10 needs to pass between the two limiting blocks 2 to realize the guiding, as shown in FIG. 2 , between the two limiting blocks 2 is the guiding channel 3, and the side of the two limiting blocks 2 facing the guiding channel 3 is the limiting side 21, that is, the two limiting sides 21 cooperate to form the guiding channel 3 , is used to limit the position of the workpiece 10 in the guiding channel 3 when the workpiece 10 passes through, then the annular area formed by the two limiting sides 21 rotating one turn along the turntable 7 is the preset detection area, and passing The workpiece 10 of the guide channel 3 must be located in the preset detection area, and the positioning is accurate; and in a possible implementation of this specification, the limit side 21 is an arc-shaped edge. When the workpiece 10 passes by, if the feeding area If the placement position of the workpiece 10 in 71 deviates from the preset detection area, at least one limit edge 21 can contact and be tangent to the edge of the workpiece 10, thereby applying a thrust towards the guide channel 3 to the workpiece 10, pushing the workpiece 10 to fall. It is easy and convenient to enter the preset detection area.

Specifically, in a possible implementation of this specification, a safety distance is set in the guiding channel 3 between the two limit sides 21, and the safety distance is the minimum distance reserved along the diameter direction of the turntable 7, that is, The minimum setting width of the guide channel 3 is equal to the sum of the maximum width of the workpiece 10 and the safety distance, so as to ensure that when the workpiece 10 passes, it will not be stuck by the two limit sides 21, resulting in failure of the limit and abnormal accumulation of the workpiece 10.

Specifically, as shown in the accompanying drawing 2 of the specification, the two limit blocks 2 are misplaced so that the centers of the two limit blocks 2 are not located on the same diameter of the turntable 7; along the diameter direction of the turntable 7, Assuming that a limit block 2 that is farther from the center of the turntable 7 is the first limit block, and a limit block 2 that is closer to the center of the circle is the second limit block, then the misalignment setting can be that the first limit block is at the circumference Direction (here and the following circumferential direction includes the positive direction and the negative direction along the rotation direction of the turntable 7) is closer to the feeding area 71, and the second limit block is correspondingly farther away from the feeding area 71; it can also be set Because the first limiting block is farther away from the feeding area 71 in the circumferential direction, and the second limiting block is correspondingly closer to the feeding area 71; in this embodiment, the first limiting block can be optionally arranged on the connecting block 1 close to the end face of the feeding area 71, and the second limit block can be optionally arranged on the end face of the connecting block 1 far away from the feeding area 71, at this time, the distance between the first limit block and the second limit block The distance is the farthest, but in other possible implementations, the distance between the first limit block and the second limit block in the direction of rotation of the turntable 7 can also be selected to be smaller than the distance in this embodiment, and the present invention does not make any It is limited, as long as the distance between the two in the circumferential direction is greater than zero, that is, the two are arranged in a misaligned direction in the circumferential direction, and such an arrangement can be within the protection scope of the present invention.

Specifically, the dislocation setting is also beneficial to avoid the workpiece 10 from being jammed and piled up; The front end of the front end, that is, the end close to the feeding area 71 can be set as a transition edge 22, and the rear end of the transition edge 22 is connected to the front end of the limit edge 21. The transition edge 22 is a gradual structure in the horizontal direction, that is, the transition edge 22 is formed by The width of the guiding channel 3 is greater than the width of the guiding channel 3 formed at the rear end of the transition edge 22, so that the guiding channel 3 forms an outer figure-eight channel as a whole, that is to say, the workpiece 10 rotates with the turntable 7 to the turntable type detection When the position of the guiding mechanism of the equipment can be raised and lowered, the width of the entrance of the guiding channel 3 is larger than the width of the middle part, so that the workpiece 10 can enter the guiding channel 3 smoothly, and the width limitation of the middle part effectively limits the workpiece 10 to move along the turntable. 7 the position on the diameter direction, and then the width of the exit is also greater than the width of the middle part, which is convenient for the workpiece 10 to pass through smoothly, and avoids the failure of the entire turntable type detection equipment caused by a plurality of workpieces 10 piled up at the exit.

Specifically, in the vertical direction, as shown in Figure 1, the liftable guiding mechanism of the turntable type detection equipment also includes a lifting member 4, a lifting cylinder 5 and a fixing member 6, wherein, as shown in Figure 3, the fixing member 6 is used to fix the lifting and guiding mechanism of the turntable type detection equipment around the turntable 7, and the fixing piece 6 is also fixedly connected with the lifting cylinder 5, so that the lifting cylinder 5 is fixed stably and reliably; and the lifting cylinder 5 and the lifting piece 4 It is relatively movable in the vertical direction, and the lifting cylinder 5 is used to provide power for the movement of the lifting member 4, so that the lifting member 4 can move up and down under the driving force of the lifting cylinder 5, and the lifting member 4 is also connected with the lifting member 4. The connection block 1 is fixedly connected to enhance the structural strength of the liftable guiding mechanism of the turntable type detection equipment, reduce the load of the connection block 1, and prolong the overall service life of the liftable guiding mechanism of the turntable type detection equipment, then when the lifting cylinder 5 outputs When powered, the lifting member 4 can drive the connecting block 1 and the limiting block 2 to move up and down together; in addition, in a possible implementation of this specification, on the basis of ensuring the overall structural strength, the lifting cylinder 5 can be directly connected to the Block 1 is relatively movable, which further simplifies the structure, improves the driving efficiency, and saves energy.

In addition, corresponding to the lifting cylinder 5, in a possible embodiment of this specification, a transverse driving member can also be provided for driving the connecting block 1 to move along the diameter direction of the turntable 7, so that the guiding channel 3 and the turntable 7 The distance between the centers of the circles is adjustable, the fault tolerance rate is high, and it can adapt to various preset detection areas to expand the scope of application.

Specifically, the limit block 2 moves up and down synchronously with the lifting of the connecting block 1, and enters the normal working state when the alignment is performed, and the lifting cylinder 5 is driven down; on the contrary, when it is converted into a standby state, the lifting cylinder 5 is controlled to drive up; In order to ensure that the limit block 2 will not hinder the rotation of the turntable 7 when it descends, or cause damage to the equipment due to bumping against the turntable 7, the limit block 2 has the lowest position when it moves in the vertical direction, and it is in the lowest position state, that is, it is in the normal working state , the height of the lower surface of the limiting block 2 is lower than the upper surface of the workpiece 10, so as to ensure that the limiting edge 21 can touch the workpiece 10, and apply a thrust to it for guidance, but at the same time, the height of the lower surface of the limiting block 2 is higher than The height of the bottom surface of the workpiece 10 is also higher than the height of the upper surface of the turntable 7 to ensure sufficient safety, avoid unnecessary equipment damage, and reduce maintenance costs; The height difference reserved between them can be selected as 3-5mm, which not only ensures that the position of the workpiece 10 can be effectively corrected, but also avoids damage caused by the limit block 2 bumping the turntable 7, or scratches on the surface of the turntable 7, which will affect the detection results. accuracy.

When the turntable type testing equipment is turned on, the turntable 7 starts to rotate, then the lifting cylinder 5 in the liftable guiding mechanism of the turntable type testing equipment outputs power to drive the lifting part 4 down, and at the same time drive the connecting part 1 and the two limit blocks 2 down synchronously , until it descends to the preset lowest position, stops descending, and starts to enter the working state, and guides the passing workpieces 10 one by one, so that the workpieces 10 fall into the ring-shaped area where the guiding channel 3 is located, which is convenient for subsequent detection; At the end of the detection, the lifting cylinder 5 outputs power in reverse, drives the lifting part 4 to rise, drives the connecting part 1 and the two limit blocks 2 to rise synchronously, until it rises to the original position height, stops rising, enters the standby state or closes, and waits The opening of the next round of detection has accurate positioning, convenient operation, simple structure and low energy consumption.

And for the whole turntable type testing equipment, the blanking area is arranged after the last testing mechanism 8, and is used to take away the workpiece 10 that has been tested from the turntable 7, but, in the rotation process of the turntable, it may happen that after the detection In the case that the workpiece 10 is accidentally missed in the blanking area, the cleaning combination mechanism 9 is provided with a rejecting station 92, which is positioned after the blanking area. As shown in Figure 4, the rejecting station 92 is located after the blanking area and next to the next Before turning the feeding area, it is used to remove the workpieces 10 left on the turntable 7 after the unloading area, that is, it can absorb the accidentally missed workpieces 10, so as to leave the turntable 7, and prevent these workpieces 10 from following the next turn of the turntable 7 Rotation enters the feeding area 71 again, which affects the next round of detection; similarly, in order to ensure the accuracy of detection, a cleaning station 91 is also set in the cleaning combination mechanism 9 to clean the surface of the turntable 7 and ensure the cleanliness of the surface of the turntable 7 , to avoid adverse effects on the accuracy of the detection results; in addition, the control mechanism can control the rejecting station 92 and the cleaning station 91 to work at the same time, that is, the cleaning combination mechanism 9 works synchronously to clean the workpiece 10 and the turntable 7. The cleaning process is completed synchronously, and the cleaning station 91 does not take up extra time for cleaning, which saves time and speeds up the detection efficiency; while the cleaning combination mechanism 9 is working, the control mechanism controls the feeding area 71 to stop feeding to avoid cleaning by mistake, but at the same time Maintain the normal operation of the liftable guide mechanism and four detection mechanisms 8 of the turntable type detection equipment, avoid unnecessary energy consumption caused by repeated opening and closing, more energy-saving and efficient, and save operating costs.

Wherein, as shown in Figure 5, the cleaning station 91 includes two dust removal structures arranged symmetrically with the horizontal plane as the axis of symmetry, which are respectively located above and below the turntable 7, that is, the two dust removal structures are symmetrically arranged about the turntable 7, and the two dust removal structures The structure is turned on or off at the same time. The upper dust removal structure is used to clean the upper surface of the turntable 7, while the lower dust removal structure is used to clean the lower surface of the turntable 7, so as to ensure that the upper and lower surfaces of the turntable 7 are kept clean and have high transparency; what needs to be explained Yes, the cleaning station 91 can complete the cleaning during the rotation of the turntable 7, and there is no need to reserve additional time to stop the turntable 7 before cleaning, avoiding energy loss and time loss caused by unnecessary switching processes, and the cleaning is efficient and fast .

Rotating automatically cleans, which is convenient and fast, with a high degree of automation and saves manpower; Top cylinder, simple and convenient assembly, low cost, direct drive mode, less energy loss.

Specifically, as shown in Figure 5 of the specification, the elastic cleaning part includes a cleaning part and an elastic cleaning part 912, wherein the upper end of the elastic cleaning part 912 is used to connect with the driving part 911, and the lower end of the elastic cleaning part 912 is connected to the cleaning part. The top is fixedly connected, and the cleaning part is used to descend under the driving of the driving part 911 until it contacts the turntable 7 to remove dust. The elastic cleaning part 912 is located between the driving part 911 and the cleaning part, and the cleaning part can be adjusted when the cleaning part descends Adjust the distance between the bottom of the cleaning part and the turntable 7, and form a buffer force; especially once the driver 911 is pressed down excessively and the bottom of the cleaning part has contacted the turntable 7, the elastic cleaning part 912 can be compressed , to eliminate this part of the error caused by the driving member 911, and avoid the cleaning part from continuing to press down, resulting in damage to the turntable 7, that is, it can play a role in protecting the turntable 7; in a possible implementation of this specification, the elastic cleaning part 912 can be set as multiple floating springs, and the elastic buffering effect is good.

Specifically, as shown in Figure 6 of the specification, the cleaning part includes a connecting shaft 914 and a dust removal wheel 915 sleeved on the connecting shaft 914, wherein the connecting shaft 914 is arranged horizontally, and the outer wall of the dust removal wheel 915 is coated with a viscous dust removal wheel. Adhesive tape, then along with the rotation of turntable 7, because the position of cleaning station 91 is fixed, through the contact friction between the surface of dust removal tape and turntable 7, dust removal wheel 915 or dust removal tape can be reversed along with the rotation of turntable 7 Rotate (or roll), and the outer surface of the dust-removing tape is viscous, which can stick to the dust and dirt on the surface of the turntable 7, and take away these substances with the relative rotation between the two, so as to realize the cleaning of the surface of the turntable 7. Cleaning, high cleaning efficiency, convenient and labor-saving; in addition, in a possible implementation of this specification, the dust removal wheel 915 can be selected as a detachable setting, then the dust removal wheel 915 can be disassembled along the axial direction of the connecting shaft 914, so that Quickly replace the used dust removal wheel 915 or dust removal tape, which is convenient, fast and low in cost; similarly, in other possible implementations of this specification, only the dust removal tape can be set as a detachable structure, or the dust removal wheel The 915 and the dust removal tape are set as detachable structures at the same time, so that they can be replaced synchronously, further saving time and improving efficiency.

It should be noted that when the cleaning station 91 is in a standby state, in order to ensure that the cleaning station 91 will not hinder the normal rotation of the turntable 7, the lowest point of the elastic cleaning member, that is, the bottom of the dust removal tape and the upper surface of the turntable 7 There is a safety distance between them; in a possible implementation of this specification, considering that the workpieces carried on the turntable 7 can pass smoothly without being accidentally stuck, in the standby state, the height range of the safety distance can be set to 2 ~5cm; in other possible implementations of this specification, the height range of the safety distance can also be adaptively set according to the thickness of the workpiece carried on the turntable 7, as long as the workpiece can not be in contact with the cleaning station 91 during the normal detection process And when the cleaning station 91 is in working condition, the driving member 911 can drive the elastic cleaning member to move down until it touches the rotating disk 7, and then it can automatically clean with the rotation of the rotating disk 7; Finally, the driving member 911 drives the elastic cleaning member to move upwards, away from the turntable 7, until the height range between the two returns to a safe distance, which is convenient and fast, and saves time.

Specifically, in order to further strengthen the internal structural strength of the elastic cleaning part and enhance durability, a first connecting part 913 is also provided between the connecting shaft 914 and the elastic cleaning part 912, the contact area is larger, and the force of the connecting angle is more dispersed.

The information is transmitted to the control mechanism. When it is detected that there are workpieces on the surface of the turntable 7 after the unloading area, the control mechanism controls the rejecting station 92 to approach the turntable 7 for removal. After the second detection sensor detects that the workpiece disappears, the control mechanism The monitoring information of the second detection sensor can be collected, so as to control the rejecting station 92 away from the turntable 7 and restart standby or shut down, which is convenient, fast and highly automated.

In this embodiment, the control mechanism can control the rejecting station 92 and the cleaning station 91 to work at the same time, and the cleaning process is completed synchronously during the rejecting process, and the cleaning station 91 does not take up extra time for cleaning, saving time and speeding up detection efficiency; and When the rejecting station 92 and the cleaning station 91 are working, the control mechanism controls the feeding area to stop feeding at the same time, so as to avoid mistaken cleaning during the rejecting and cleaning process. It can work normally, avoid unnecessary energy consumption caused by repeated opening and closing, is more energy-saving and efficient, and also saves operating costs; in addition, in a possible implementation of this specification, the first detection sensor and the second detection sensor can be set to the same One, saving the number and cost of sensors, and occupying a smaller space on the turntable 7, avoiding the phenomenon that one of the sensors mistakenly recognizes the other sensor as a stain, and reducing the possibility of detection errors.
