Detailed Description

The present application is described in detail below with reference to the attached drawings.

This application has provided an industrial digital production online quality intellectual detection system sorting unit for overcoming prior art's not enough, utilize the irregular columniform structural feature of round pin axle self, improve current round pin axle transfer passage and proposed first round pin axle transfer mechanism and round pin axle detection mechanism that uses with it, can not only keep standing of round pin axle in detecting the intracavity throughout and placing the gesture, satisfy the not unidimensional of round pin axle under the different models, and can realize under the condition of the bionical arm that does not rely on complexity and cost height to the round pin axle all-round outward appearance detection, this application has avoided complex equipment and loaded down with trivial details technology and has realized lower cost and more excellent detection effect with the help of the ring week difference in height of round pin axle promptly.

Fig. 1 shows a simplified schematic diagram of the overall structure of the industrial digital production online quality intelligent detection sorting device provided by the present application, and the device has a detection cavity 5 and a pin conveying channel 1. Pin shaft conveying channel 1 is arranged above detection cavity 5, and conveys pin shaft 6 to detection cavity 5 from top to bottom for appearance detection and mechanical sorting. As shown in fig. 1 and 4, the pin shaft conveying channel 1 may be divided into a first channel inner wall section 17, a second channel inner wall section 18, and a third channel inner wall section 19 in this order. The pin conveyor channel 1 is provided with a transport mechanism 20 in its inner wall. The conveyor belt of the conveyor means 20 runs continuously along the second channel inner wall section 18 and the third channel inner wall section 19 for conveying the pins 6.

The length of the first channel inner wall section 17 is shorter than the length of the pin 6 at the shortest dimension. So that one end of the pin 6 placed in the first channel inner wall section 17 abuts against the conveyor belt on the second channel inner wall section 18. The conveyer belt opens and to drive round pin axle 6 and move towards detection chamber 5. In the process, the plurality of pins 6 can be driven by the conveyor belt to move forwards, unnecessary pressure action cannot be generated between the front pin 6 and the rear pin 6, and meanwhile, the unexpected abrasion of the pins 6 is greatly reduced.

In order to transfer the pins 6 from the pin conveyor channel 1 to the test chamber 5 and to avoid the occurrence of unintended wear and tear in the process due to the pins 6 falling down and impacting the inner wall as in the prior art, a plurality of first-tier pallets 7 are provided on the conveyor belt. A plurality of first cascade cards 7 are arranged in series along the length of the conveyor belt. The first hierarchical pallet 7 has an open end for receiving the body portion of the pin 6.

In the present application, a plurality of pins 6 are dropped to the pin conveyor channel 1 in a consistent dropping direction. The casting direction means that the pin cap 16 of the pin 6 is always at a higher level than the free end of the pin body 15. The first and second channel inner wall sections 18 are both downward inclined slopes, i.e. when the pin 6 is dropped, the end of the pin cap 16 contacts the first channel inner wall section 17, and the free end of the pin body 15 contacts the second channel inner wall section 18. From this, when placing the round pin axle 6 that will detect on round pin axle transfer passage 1, transport mechanism 20 starts, and first hierarchical formula cardboard 7 moves upwards along the conveyer belt and makes round pin axle 6 enter until butt between round pin axle 6 and the cardboard from the open end of cardboard. The transmission mechanism is started, and simultaneously, the first-level clamping plate 7 and the pin shaft 6 are driven to move downwards.

Preferably, the release of the pin shaft 6 can be manually operated, a placing point is drawn on the inner wall of the first channel in advance, and an operator only needs to place the pin shafts 6 one by one in a mode that the pin shaft caps 16 are aligned with the placing point. Preferably, the release of the pin 6 can also be a mechanical automation with controllable operating times.

The third channel inner wall section 19 extends vertically with respect to the ground, whereby the pin 6 entering this inner wall section changes from an inclined state to a vertical position. At this time, the first hierarchical pallet 7 abuts against the lower end surface of the pin boss 16, and the pin 6 is kept from being separated from the pallet.

The first pin transfer mechanism 2 can take the pin 6 off the first hierarchical pallet 7. The first hierarchical pallet 7 without the pin 6 rotates along with the conveyor belt and returns to the first channel inner wall section 17 again to support a new pin 6 to be detected.

Preferably, a collecting means is provided at the vertical bottom end of the third channel inner wall section 19. Therefore, if a certain pin shaft 6 cannot be effectively transferred by the first pin shaft transfer mechanism 2 in the operation of releasing the pin shaft 6, namely the first-layer clamping plate 7 cannot be clamped, the pin shaft 6 which fails to be released still moves along with the conveyor belt until falling down at the turning part between the second and third channel inner wall sections 19, and is collected by the collecting mechanism for releasing again. The collection mechanism may be a conveyor belt. The collecting mechanism can be designed to extend to the outside of the detection cavity 5 to be observed by an operator, and the operator can clearly determine the internal operation condition, so that the parameters of the device and the like can be timely adjusted, and the serious influence caused by the fact that the pin shaft 6 fails to transfer in time in the prior art is also avoided.

As shown in fig. 5, the hierarchical cardboard is plate-shaped structure, and it is fixed on the conveyer belt with the gesture of placing perpendicularly, and the one end that deviates from the conveyer belt on its plate body has the breach that is open form, and the inward flange of this breach extends towards conveyer belt place side, and the inward flange of this breach forms the shape that can adapt to the round pin axle body 15 of different model round pin axles 6 on the plate body. The shape may be a multiple step incremental bracket like a gourd-shaped profile. The notch is gradually increased from the degree of curvature of the bracket shape at the opening, and when the pin shaft 6 is thrown in, the pin shaft 6 can be clamped to the position matched with the diameter size of the notch of the hierarchical clamping plate based on the inclined first and second channel inner wall sections 18.

Preferably, the end of the level gauge at which the notch is located may be provided with a bent bar 24. The bodies of the bending rods 24 are all parallel to the plates of the layered clamping plates. The bending rod 24 is arranged in a hollow inner cavity formed on the clamping plate. The bending point of bending rod 24 is pivotally connected within the hollow interior of the catch plate. The first support rod of the bending rod 24 is arranged at the side of the notch, and the second support rod extends out of the clamping plate body. When aligning round pin axle 6 the breach and putting in, round pin axle 6 contacts first branch and its gravity forms the exogenic action to first branch, and first branch rotates towards the breach is inside, and the synchronous inwards rotation of second branch and butt to round pin axle body 15 are last.

Preferably, bending rods 24 are mechanically controlled. The first sensor is arranged on the first rod body of the bending rod 24, and can sense that the pin shaft 6 is thrown into the notch. After sensing that the pin shaft 6 is thrown into the notch, the driving bending rod 24 is driven to rotate towards the inside of the notch, and the second rod body is provided with a second sensor which can sense whether the second rod body is in contact with the pin shaft 6. The sensor may be an acceleration sensor, a pressure sensor, or the like. With the second sensor, the second rod body can always maintain its contact relationship with the pin shaft body 15. Therefore, the pin 6 cannot be separated from the clamping plate in the conveying process of the pin 6.

The first pin transfer mechanism 2 includes a first turntable base 21 controllably rotatably connected in the inner wall of the detection chamber 5. The first pin transfer mechanism 2 can take the pin 6 to separate from the first hierarchical pallet 7 along the notch of the first hierarchical pallet 7. The pin 6 conveying mechanism is arranged above the first pin transfer mechanism 2 according to the condition that the opening direction of the notch of the first hierarchical clamping plate 7 is the tangential direction of the first rotary table base 21.

The first pin shaft transfer mechanism 2 comprises a second level type clamping plate 8, the first turntable base 21 rotates, and the second level type clamping plate 8 is in contact with the pin shaft 6 and exerts a thrust effect on the pin shaft 6 under the continuous rotation of the first turntable base 21. When the second sensor collects sensing data exceeding a preset pressure threshold value, the second rod body is indicated to rotate reversely to release the pin shaft 6. The pins 6 are thereby transferred from the pin conveyor channels 1 onto the second level cards 8.

Preferably, the first and second level cards 8 are identical in structure.

The device further comprises a pin detection mechanism 3, wherein the pin detection mechanism 3 comprises a first image collector 10 and two second image collectors 12, as shown in fig. 3, the first image collector 10 and the second image collector 12 are respectively arranged at two different positions around the circumference of the first turntable base 21. As shown in fig. 2, two second image collectors 12 are disposed opposite to each other on the inner wall of the detection cavity 5, respectively, and are used for collecting image data of the upper and lower end surfaces of the pin 6 to be detected.

The pin detection mechanism 3 further includes an auxiliary column 9 located closer to the first turntable base 21 with respect to the first image collector 10. The auxiliary column 9 can be driven by external force to extend and retract up and down and rotate. According to the mode that the center of the auxiliary column 9 corresponds to the shaft center of the pin shaft 6, the second-level clamping plate 8 can move to the position right above the position of the auxiliary column 9 in a rotating mode of the first turntable base 21. The auxiliary column 9 can extend up and down to abut against the bottom end face of the pin shaft 6 and is fixed relative to the bottom end face of the pin shaft 6, so that the pin shaft 6 can be driven to move up and down and/or rotate.

The second hierarchical cardboard 8 is arranged on the vertical rod 23, and the vertical rod 23 is fixedly arranged at the edge position of the first turntable base 21. The vertical rod 23 is further provided with a telescopic mechanism 25, and the telescopic mechanism 25 can drive the second-level clamping plate 8 to move towards the direction far away from or close to the vertical rod 23. Because second image collector 12 collects the image data of the lower end surface of pin shaft 6, the position data of the central position of the lower end surface of pin shaft 6 in detection cavity 5 can be analyzed and obtained. Based on the predetermined relative position relationship between the second image collector 12 and the auxiliary column 9 and the relative position relationship between the shaft center of the auxiliary column 9 and the disc, the relative position relationship between the center position of the lower end surface of the current pin shaft 6 to be detected and the shaft center of the auxiliary column 9 can be calculated. Based on the calculation result, the rotation angle of the first turntable base 21 and the telescopic length of the telescopic mechanism 25 on the vertical rod 23 can be determined. Thereby making the center of the auxiliary column 9 correspond to the axial center of the pin shaft 6.

The auxiliary columns 9 are fixed relatively to the pin shaft 6 or isolated from each other based on the opening and closing of the composite microarray arranged on the top end face of the auxiliary columns. Because the upper end joint of round pin axle 6 is in the breach of second level formula cardboard 8, auxiliary column 9 can take round pin axle 6 to rotate steadily from this. The first image collector 10 is aligned with the corresponding detection area above the auxiliary column 9, so that the pin shaft 6 can be subjected to full-circle image collection under the condition that the pin shaft 6 rotates. The full circumferential image acquisition may refer to the complete acquisition of the side faces of the pin 6 in the circumferential direction.

The composite microarray can be a gecko bionic mushroom array structure, the auxiliary column 9 is provided with a through hole, a vacuum suction nozzle is embedded in the through hole, and the vacuum suction nozzle is connected with a negative pressure supply mechanism. The high-strength adhesive force of the gecko bionic mushroom-shaped array structure is utilized, so that the composite microarray can obtain the large adhesive force of the composite microarray on the end face of the bottom of the pin shaft 6 under the condition of small vacuum degree. The gecko bionic mushroom array structure can reduce the vacuum degree of negative pressure. When negative pressure is applied, normal prestress can be generated on the gecko bionic mushroom array structure, and the adhesive force of the gecko bionic mushroom array structure is increased.

The second hierarchical cardboard 8 shields part of the pin shaft body 15, and the shielded part forms a first shielded area. And a second shielding area is formed on one side of the pin shaft 6 to be detected, which deviates from the image collector. The first shielding area and the second shielding area can be eliminated by driving the auxiliary column 9 to drive the pin shaft 6 to move up and down and rotate. The first image collector 10 realizes the full circumferential collection of the pin shaft 6 based on the image collection operation of at least two time-sharing. Time sharing may refer to different times.

The second pin transfer mechanism 4 includes a second turntable base 22 and at least one clamping portion 13. The first turntable base 21 is arranged side by side with the first turntable base 21. The clamping portion 13 has an arc-shaped plate-like structure. The clamping portion 13 may be fixed to the edge of the second turntable base 22 by a vertical rod 23. A plurality of airbag strips which are vertically arranged and are arranged side by side are arranged on the inner wall of the clamping part 13. The air bag strip is connected with a negative pressure supply mechanism. The negative pressure supply mechanism can be used for air inflation and air suction. At least one sensor can be arranged on the plate body of the clamping part 13 and used for sensing whether the pin shaft 6 is placed in the clamping part 13.

Based on the size data of the pin shaft 6 to be transferred on the first pin shaft transfer mechanism 2, the opening of the valve at the inflating end corresponding to at least one air bag strip on the clamping portion 13 is regulated and controlled, when the sensor senses that the pin shaft 6 is placed in the clamping portion 13, the negative pressure supply mechanism is driven to operate, and the air bag strip inflates and expands to encircle the pin shaft 6 in the clamping portion 13.

The transferring operation of the first pin transferring mechanism 2 is performed by means of the relative movement speed difference between the first turntable base 21 and the conveyor belt on the pin conveying channel 1. Likewise, the transfer operation of the second pin transfer mechanism 4 is performed by means of the relative movement speed difference between the first and second turntable bases 22.

The first and second turntable bases 22 rotate in opposite directions.

Preferably, each second level card 8 corresponds to an identification code. An identification code sorting table is available along the circumferential direction of the first turntable base 21.

Preferably, the identification codes may be provided on the sides of the first carousel base 21 at positions corresponding to the second level cards 8. An auxiliary base arranged opposite to the first turntable base 21 is arranged below the auxiliary column 9, and a first recognizer is arranged on the auxiliary base. The identifier may be a third image collector to identify the identification code.

Preferably, the identification code may be provided on a vertical bar 23 on the first turntable base 21 towards the side of the second image collector 12. Preferably, the identification code can be provided on the end of the first pallet 7 facing the side on which the second image collector 12 is located. Thus, by analyzing the image data acquired by second image acquisition device 12, the identification code corresponding to the image data can be obtained at the same time.

Preferably, a second identifier is provided on a side surface of the second turntable base 22 at a position corresponding to each clamping portion 13 to identify the identification code.

The pin detection mechanism 3 may acquire the size data and the appearance data of the pin 6, and bind the analysis result, the size data, and the appearance data, which are obtained based on the analysis of the data, with the identification code acquired by the first identifier.

The clamping part 13 can regulate and control the clamping space thereof based on the size data of the pin 6 to be transferred acquired by the pin detection mechanism 3 so as to realize stable transfer of the pin 6 with different sizes. When the identification code located one bit before the identification code is acquired by at least one second identifier, the identification code corresponding to the pin 6 to be transferred next and the clamping portion 13 corresponding to the pin 6 to be transferred next can be determined based on the identification code sorting table. Based on this, the operation of the holding portion 13 corresponding thereto can be regulated in advance based on the analysis result, the dimensional data, and the appearance data of the pin 6 to be transferred next. Preferably, when the diameter of the pin 6 to be transferred is small, the clamping portion 13 corresponding thereto is set to inflate the airbag strip at a position closer to the center thereof.
