Description

Technical Field

[0001] The present application relates to the field of automatic feeding, and in particular, to an automatic feeding device and a detection and control method. Background Art

[0002] Currently, when performing processing operations such as grinding and polishing on parts such as metal shafts, in order to improve the production efficiency of the parts and the safety of the part processing process, an automatic feeding method is usually adopted to add raw materials.

[0003] In the related art, a Chinese patent with the publication number CN216127042U discloses an automatic feeding device, which includes a base, a feeding component, and a transmission component. The feeding component includes a receiving bin for placing the metal shaft, a connector, a moving plate, and a vertical driving member. A shaft transportation groove for placing a single metal shaft is formed on the moving plate. The vertical driving member is used to drive the moving plate to move upward, so that the metal shaft in the shaft transportation groove falls into the connector. A sliding channel for the metal shaft to slide through is formed in the connector. The metal shaft falls onto the transmission component through the sliding channel, and then a single metal shaft is transported between two friction rollers for grinding and polishing the metal shaft.

[0004] In view of the above related art, the inventor found that since there are many types of metal shafts, for example, some specific metal shafts have distinguishing features such as bosses at the ends, resulting in certain differences between the two ends of the metal shaft. At this time, the friction rollers need to grind the end of the metal shaft that needs to be processed. Therefore, during the process of placing the metal shaft in the receiving bin, it is necessary for the staff to distinguish the ends of the metal shaft and place the end of the metal shaft that needs to be processed on the side of the receiving bin close to the friction rollers, thereby increasing the workload of the staff. Summary of the Invention

[0005] In order to reduce the workload of the staff in selecting and differentially placing the metal shafts, the present application provides an automatic feeding device and a detection and control method.

[0006] In a first aspect, the present application provides an automatic feeding device, adopting the following technical solution:

[0007] An automatic feeding device includes a receiving bin for placing a metal shaft;

[0008] An ejecting component for individually ejecting the metal shaft in the receiving bin;

[0009] A sliding channel for receiving the metal shaft ejected by the ejecting component. A second blocking component and a first detection device are arranged on the sliding channel. The first detection device is used to detect the end processing position of the metal shaft in the sliding channel, and the second blocking component is used to block or release the metal shaft in the sliding channel according to the detection result of the first detection device;

[0010] The first pushing component, the first pushing component includes a first transport table and a first pushing driving member. A first sliding groove for receiving the metal shaft falling from the sliding channel is formed on the first transport table, and the first pushing driving member is used to push the metal shaft in the first sliding groove into the first friction mechanism.

[0011] The second pushing component, the second pushing component includes a second transport table and a second pushing driving member. A second sliding groove for receiving the metal shaft falling from the sliding channel is formed on the second transport table, and the second pushing driving member is used to push the metal shaft in the second sliding groove into the second friction mechanism.

[0012] By adopting the above technical solution, the end position of the metal shaft is detected by the first detection device, and then the metal shaft is blocked or squared by the second blocking component to adjust the speed of the metal shaft sliding out of the sliding channel, so that the metal shaft falls on the first transport table or the second transport table, and then is sent into the first friction mechanism or the second friction mechanism. By setting the first detection device, the staff can directly put a plurality of metal shafts into the storage bin, thus reducing the workload caused by distinguishing and placing the metal shafts.

[0013] Optionally, a first shaft storage box is arranged at the bottom of the first transport table, a first dropping opening for the metal shaft in the first sliding groove to fall into the shaft storage box is arranged on the first transport table, and a first lifting driving member is arranged at the bottom of the first shaft storage box. The driving part of the first lifting member slidably penetrates through the shaft storage box and is used to support the metal shaft.

[0014] By adopting the above technical solution, by setting the first oil storage tank, the quantity control of the metal shafts in the first transport box is carried out, so that the situation of too many or too few metal shafts on the first transport table is not likely to occur.

[0015] Optionally, a first support block for filling the first dropping opening is arranged on the first transport table. The top of the first support block is the bottom of the first sliding groove, and the first support block is connected with a first opening cylinder for driving the first support block to move.

[0016] By adopting the above technical solution, by setting the first support block, the sliding movement process of the metal shaft in the first dropping opening is made smoother.

[0017] In a second aspect, the automatic feeding detection control method includes:

[0018] Obtain the end processing position information of the metal shaft, and the end processing position information includes left processing position information and right processing position information;

[0019] Generate second blocking control information according to the corresponding relationship between the preset end machining position information and the second blocking control information;

[0020] Emit second blocking control information for controlling the operation of the second blocking component;

[0021] Obtain pushing control information according to the corresponding relationship between the preset end machining position information and the pushing control information;

[0022] Emit pushing control information for controlling the first pushing driving part or the second pushing driving part to push the metal shaft.

[0023] Optionally, obtain a first quantity, where the first quantity represents the number of metal shafts on the first transport table;

[0024] Obtain first pushing stroke information according to the corresponding relationship between the first quantity and the first pushing stroke information of the first pushing driving part. The first pushing stroke information includes first to-be-machined station stroke information and first machining station stroke information;

[0025] Obtain a machining time value;

[0026] Judge whether the first machining time value is greater than the preset full machining time value;

[0027] If so, judge whether there is a metal shaft rolling onto the first transport table according to the end machining position information. When and only when there is a metal shaft rolling onto the first transport table, emit pushing control information for controlling the first pushing driving part to push the metal shaft according to the first machining station stroke information;

[0028] If not, judge whether there is a metal shaft rolling onto the first transport table according to the end machining position information. When and only when there is a metal shaft rolling onto the first transport table, emit pushing control information for controlling the first pushing cylinder to push the metal shaft according to the first to-be-machined station stroke information.

[0029] By adopting the above technical solution, when the number of metal shafts on the first conveyor changes, the pushing stroke of the first pushing driving part also changes accordingly. Therefore, it is necessary to adjust the pushing stroke of the first pushing part according to the first quantity. At the same time, according to whether the previous metal shaft is processed, control whether the first pushing driving part needs to push the next metal shaft into the first friction mechanism or the second friction mechanism.

[0030] Optionally, when the first quantity reaches the preset first saturation quantity;

[0031] Emit a first release message, where the first release message is used to control the driving part of the first lifting driving part to move downward so that the metal shaft falls from the bottom of the first dropping port into the first shaft storage box.

[0032] By adopting the above technical solution, when the quantity on the first transport table reaches a certain amount, the metal shafts on the first transport table are temporarily stored in the first shaft storage box.

[0033] Optionally, when the first quantity reaches the first compensation quantity;

[0034] A first compensation message is sent, and the first compensation message is used to control the piston rod of the first lifting cylinder to rise so that the metal shaft re-enters the first transport table.

[0035] By adopting the above technical solution, when the number of metal shafts on the first transport table is small, the metal shafts originally stored in the first shaft storage box are pushed back onto the first transport table, so that it is not easy for the first transport table to lack metal shafts.

[0036] Optionally, the automatic feeding detection control method further includes a method for controlling the quantity of metal shafts in the first shaft storage box and the second shaft storage box:

[0037] Obtain the end processing position information of all metal shafts in the accommodation bin;

[0038] According to the end processing position information of all metal shafts in the accommodation bin, obtain the quantity of the processing ends corresponding to the first side plate of the accommodation bin and the quantity of the processing ends corresponding to the second side plate of the accommodation bin;

[0039] Calculate the first processing allowance value according to the sum of the first quantity and the number of metal shafts in the first shaft storage box;

[0040] Calculate the second processing allowance value according to the sum of the second quantity and the number of metal shafts in the second shaft storage box;

[0041] When the first processing allowance is greater than the second processing allowance;

[0042] If the quantity of the processing ends corresponding to the first side plate is greater than the quantity of the processing ends corresponding to the second side plate, a reminder signal for reminding the staff to make the first side plate correspond to the second pushing component is sent. If the quantity of the processing ends corresponding to the first side plate is less than the quantity of the processing ends corresponding to the second side plate, a reminder signal for reminding the staff to make the first side plate correspond to the first pushing component is sent;

[0043] When the first processing allowance is less than the second processing allowance;

[0044] If the quantity of the processing ends corresponding to the first side plate is greater than the quantity of the processing ends corresponding to the second side plate, a reminder signal for reminding the staff to make the first side plate correspond to the first pushing component is sent. If the quantity of the processing ends corresponding to the first side plate is less than the quantity of the processing ends corresponding to the second side plate, a reminder signal for reminding the staff to make the first side plate correspond to the second pushing component is sent.

[0045] By adopting the above technical solution, according to the first machining allowance and the second machining allowance, the remaining workloads of the first friction mechanism and the second friction mechanism are counted, so that by adjusting the placement direction of the next receiving bin, the newly added workloads of the subsequent first friction mechanism and the second friction mechanism are adjusted, and thus the situation that there are too many or too few metal shafts in the first shaft storage box is not likely to occur.

[0046] Optionally, it includes obtaining the moving image information of the metal shaft in the connector;

[0047] According to the moving image information of the metal shaft, the moving offset direction information of the metal shaft is obtained;

[0048] According to the corresponding relationship between the end machining position information and the moving offset direction information, the end machining position information of the metal shaft is obtained.

[0049] By adopting the above technical solution, when the shape sizes at both ends of the metal shaft are relatively close, compared with the method of graphic recognition, by judging the moving trajectory of the metal shaft, the recognition result of the end position of the metal shaft is more accurate.

[0050] In summary, the present application includes at least one of the following beneficial technical effects:

[0051] 1. Reduce the workload of the staff in selecting and placing the metal shafts separately;

[0052] 2. By setting the first shaft storage box and the second shaft storage box to adjust the quantity of the metal shafts on the first transportation platform and the second transportation platform, so that the situation that there are too many or too few metal shafts on the first transportation platform and the second transportation platform is not likely to occur;

[0053] 3. By adopting the method of moving trajectory recognition, the way of obtaining the machining end position information of the metal shaft is more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] In order to make the purpose, technical solutions and advantages of this application clearer, the following is combined with the attached Figure 1-10Embodiments are used to further elaborate on this application in detail. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0066] An embodiment of this application discloses an automatic feeding device. Refer to Figure 1 and Figure 2 , the automatic feeding device is used to push the metal shaft 9 into the first mechanism or the second friction mechanism 102 for grinding. In this embodiment, both the first friction mechanism 101 and the second friction mechanism 102 include two friction rollers 103. Among them, the end of the metal shaft 9 has a processing end 91, and the shape of the processing end 91 of the metal shaft 9 is different from the shape of the other end of the metal shaft 9. In this embodiment, the specific difference of the processing end 91 of the metal shaft 9 is that the radius of the processing end 91 of the metal shaft 9 is greater than the radius of the other end of the metal shaft 9, and a tapered portion 92 extends integrally from the processing end 91 of the metal shaft 9 near the other end of the metal shaft 9. When grinding the processing end 91 of the metal shaft 9, the processing end 91 of the metal shaft 9 is sent between the two friction rollers 103 so that the two friction rollers 103 grind and polish the processing end 91 of the metal shaft 9.

[0067] Refer to Figure 2 and Figure 3 , the automatic feeding device includes a mounting table 1, a storage bin 2, an ejection assembly 3, a sliding channel 4, a first pushing assembly 5, a second pushing assembly 6, and a first detection device 41. In this embodiment, there are two mounting tables 1, and the first friction mechanism 101 and the second friction mechanism 102 are respectively arranged on the two mounting tables 1, and the friction rollers 103 are rotatably arranged on the mounting table 1. The storage bin 2 is located between the two mounting tables 1. A first blocking assembly 43 and a second blocking assembly 44 are arranged above the sliding channel 4.

[0068] Refer to Figure 2 and Figure 3 , when the automatic feeding device works, the metal shafts 9 in the storage bin 2 enter the ejection assembly 3 one by one, the ejection assembly 3 pushes the metal shaft 9 upward, the metal shaft 9 in the ejection assembly 3 enters the sliding channel 4, the first blocking assembly 43 blocks the metal shaft 9, and then the first detection device 41 detects the end of the metal shaft 9 to judge the orientation of the processing end 91 of the metal shaft 9, so as to select the first pushing assembly 5 to push the metal shaft 9 or the second pushing assembly 6 to push the metal shaft 9, and then judge whether the second blocking assembly 44 needs to block the metal shaft 9.

[0069] Refer to Figure 2 and Figure 3, the second blocking component 44 is located below the first blocking component 43. The first pushing component 5 is located on the side of the second pushing component 6 away from the inside of the sliding channel 4. When the second blocking component 44 blocks the metal shaft 9 in the sliding channel 4, the metal shaft 9 is paused again in the sliding channel 4 and its speed is reduced to zero. When the second blocking component 44 releases the metal shaft 9, the metal shaft 9 drops onto the first pushing component 5, and then the first pushing component 5 pushes the metal shaft 9 into the first friction mechanism 101.

[0070] Referring to Figure 2 and Figure 3 , when the second blocking component 44 does not need to block the metal shaft 9 in the sliding channel 4, at this time when the metal shaft 9 slides out from the outlet of the sliding channel 4, the metal shaft 9 has a greater sliding-out speed compared to when the second blocking component 44 blocks the metal shaft 9. At this time, the metal shaft 9 can slide out of the sliding channel 4 and fall onto the second pushing component 6, and then the second pushing component 6 pushes the metal shaft 9 to the second friction mechanism 102 for friction.

[0071] Referring to Figure 4 and Figure 5 , an installation vertical plate 11 is provided on the installation table 1, an inclined plate 12 is provided on the installation vertical plate 11, two triangular plates 13 are welded and fixed to the bottom of the inclined plate 12, and the two triangular plates 13 are welded and fixed to the installation vertical plate 11, so that the inclined plate 12 is fixed to the installation vertical plate 11 through the triangular plates 13. The accommodation bin 2 is located above the inclined plate 12.

[0072] The ejecting component 3 includes an ejecting cylinder 31 welded and fixed to the installation vertical plate 11 and located below the inclined plate 12, and an ejecting plate 32 is welded and fixed to the piston rod of the ejecting cylinder 31. The ejecting plate 32 includes a sliding part 321 and a connecting part 322 integrally connected to and perpendicular to the sliding part 321, and the connecting part 322 is welded and fixed to the piston rod of the ejecting cylinder 31. There is a sliding gap 14 between the inclined plate 12 and the installation vertical plate 11 for the sliding part 321 to slide through.

[0073] Referring to Figure 5 and Figure 6, a placement groove 3211 for placing a single metal shaft 9 is formed on the sliding part 321, and the accommodating bin 2 has an accommodating outlet through which the metal shaft 9 can slide out of the accommodating bin 2. The inclined plate 12 is arranged to incline downward from the side far away from the mounting vertical plate 11 to the side close to the mounting vertical plate 11, so that the accommodating bin 2 is also arranged to incline downward from the side far away from the mounting vertical plate 11 to the side close to the mounting vertical plate 11. When the ejecting cylinder 31 drives the placement groove 3211 of the sliding part 321 to slide to a position corresponding to the accommodating outlet, the metal shafts 9 in the accommodating bin 2 roll into the placement groove 3211 one by one, and then the ejecting cylinder 31 pushes the sliding part 321 to move upward until the height of the placement groove 3211 of the sliding part 321 is higher than the height at the entrance of the sliding channel 4. The placement groove 3211 communicates with the two side walls of the sliding part 321, and the bottom of the placement groove 3211 is arranged to incline downward, so that the metal shafts 9 in the placement groove 3211 can slide into the sliding channel 4 under the action of gravity.

[0074] Referring to Figure 5 and Figure 6 , the sliding channel 4 is arranged to incline downward from the end close to the accommodating bin 2 to the end far away from the accommodating bin 2. A first mounting plate 42 and a second mounting plate are welded and fixed above the sliding channel 4. The first blocking assembly 43 includes a first blocking cylinder 431 welded and fixed on the first mounting plate 42 and a first blocking plate 432 welded and fixed on the piston rod of the first blocking cylinder 431. By driving the first blocking plate 432 to move in the vertical direction through the first blocking cylinder 431, the blocking or releasing of the metal shaft 9 in the sliding channel 4 is realized. The second blocking assembly 44 includes a second blocking cylinder 441 welded and fixed on the second mounting plate and a second blocking plate 442 welded and fixed on the piston rod of the second blocking cylinder 441, so as to realize the blocking or releasing of the metal shaft 9 passing through the first blocking plate 432.

[0075] Referring to Figure 5 and Figure 6, the first pushing component 5 includes a first transport table 51 and a first pushing driver 52 welded and fixed on the first transport table 51. A support cross plate 15 is welded and fixed on the installation vertical plate 11, and the first transport table 51 is welded and fixed above the support cross plate 15. The first pushing driver 52 can be a cylinder or an oil cylinder, or a linear module. In this embodiment, the first pushing driver 52 is a linear module. A pushing rod 521 is welded and fixed on the sliding part 321 of the linear module to realize the linear pushing of the metal shaft 9. A first sliding groove 511 for receiving the metal shaft 9 falling from the sliding channel 4 and allowing the metal shaft 9 to slide through is provided on the first transport table 51. The longitudinal section of the first sliding groove 511 along its length direction is V-shaped. The first pushing driver 52 is used to push the metal shaft 9 falling into the first sliding groove 511 onto the first friction mechanism 101, so as to polish the processing end 91 of the metal shaft 9.

[0076] Refer to Figure 5 And Figure 6 , the second pushing component 6 includes a second transport table 62 and a second pushing driver 61 welded and fixed on the support cross plate 15. In this embodiment, the second pushing driver 61 is also a linear module. A second sliding groove 63 for receiving the metal shaft 9 and allowing the metal shaft 9 to slide through is provided on the second transport table 62. The second pushing driver 61 is used to push the metal shaft 9 in the second sliding groove 63 into the second friction mechanism 102 to polish the processing end 91 of the metal shaft 9.

[0077] In this embodiment, both the first sliding groove 511 and the second sliding groove 63 can accommodate multiple metal shafts 9 at the same time. When there are multiple metal shafts 9 placed in the first sliding groove 511 and the second sliding groove 63, the metal shaft 9 being polished is pushed out by the latter metal shaft 9 between the two friction rollers 103. At the same time, a collection box 16 is welded and fixed on the installation table 1. When the metal shaft 9 is pushed out from the first friction mechanism 101 or the second friction mechanism 102, the polished metal shaft 9 falls into the collection box 16. Among them, when there is only one metal shaft 9 left in the first sliding groove 511 or the second sliding groove 63, the first pushing driver 52 or the second pushing driver 61 can push the metal shaft 9 into the collection box 16 by direct contact.

[0078] Since the polishing time of the metal shaft 9 is generally a fixed value. For example, when the polishing time required for each metal shaft 9 is 40 seconds, if the ejecting assembly 3 ejects a metal shaft 9 into the sliding channel 4 every 40 seconds at this time, that is, one feeding is completed every 40 seconds, it will cause one friction mechanism to work and the other friction mechanism to idle, resulting in a relatively low working efficiency of the friction mechanism. Therefore, in this embodiment, by increasing the feeding rate of the ejecting assembly 3, the feeding time of the ejecting assembly 3 is half of the polishing time of the metal shaft 9, that is, when one friction mechanism completes one polishing of the metal shaft 9, the ejecting assembly 3 completes two feeding processes.

[0079] Taking the metal shaft 9 that needs to be polished for 40 seconds and the ejecting mechanism feeding once every 20 seconds as an example for introduction.

[0080] Refer to Figure 3 And Figure 7 , since the distribution of the processing ends 91 of the metal shafts 9 in the accommodation bin 2 is a quadratic random distribution, it is impossible to always alternately transport the metal shafts 9 to the first transport platform 51 and the second transport platform 62. There may be multiple consecutive metal shafts 9 pushed onto the first transport platform 51. At this time, due to the limited working efficiency of the first polishing mechanism, the number of metal shafts 9 stacked on the first transport platform 51 increases, and the number of metal shafts 9 on the second transport platform 62 decreases, and even decreases to zero. In order to alleviate the consequences of the excessive stacking or lack of metal shafts 9 on the first transport platform 51 and the second transport platform 62 caused by the uneven feeding, the following measures are taken:

[0081] Refer to Figure 3 And Figure 7 , a first shaft storage box 7 for storing the metal shafts 9 is provided at the bottom of the first transport platform 51, and a second shaft storage box 8 is provided at the bottom of the second transport platform 62. The first shaft storage box 7 and the second shaft storage box 8 are respectively used to adjust and control the number of metal shafts 9 on the first transport platform 51 and the second transport platform 62. A fixed cross plate 111 is welded on the installation vertical plate 11, and the first shaft storage box 7 and the second shaft storage box 8 are both welded and fixed above the fixed cross plate 111.

[0082] Refer to Figure 7 And Figure 8 , taking the first shaft storage box 7 as an example for elaboration. A first dropping port 53 is provided on the first transport platform 51, and a first lifting driving member 71 is provided at the bottom of the first shaft storage box 7. The first lifting driving member 71 can be a cylinder or an oil cylinder, or can also be a linear module. In this embodiment, the first lifting driving member 71 is an oil cylinder. The piston rod of the first lifting driving member 71 slides through the inside of the box body, and a lifting plate 72 is welded and fixed at the end of the piston rod of the first lifting driving member 71. The lifting plate 72 is used to support the metal shafts 9 in the first shaft storage box 7 and lift and lower the metal shafts 9.

[0083] When the number on the first transport platform 51 reaches a preset first saturation number, the number of metal shafts 9 on the first transport platform 51 needs to be reduced. At this time, the lifting plate 72 moves downward, and the metal shafts 9 on the first transport platform 51 fall into the first drop port 53 or the first shaft storage box 7.

[0084] In one embodiment, the metal shaft 9 falls into the first drop opening 53. At this time, the metal shaft 9 in the first shaft storage box 7 supports the metal shaft 9 in the first drop opening 53. At the same time, the metal shaft 9 in the first drop opening 53 serves as the bottom of the first sliding groove 511 to support the metal shaft 9 moving on the first transport platform 51.

[0085] In another embodiment, in order to make the movement process of the metal shaft 9 in the first drop opening 53 and the first sliding groove 511 smoother, a first support block 54 for filling the first drop opening 53 is provided on the first transport platform 51, and the top of the first support block 54 serves as the bottom of the first sliding groove 511 to support the passing metal shaft 9. The first support block 54 is connected to the first opening cylinder 74, and the top of the first shaft storage box 7 is welded and fixed with a cylinder support plate 73. The first opening cylinder 74 is welded and fixed above the cylinder support plate 73, and the piston rod of the first opening cylinder 74 is welded and fixed to the support block, so as to move the first support block 54.

[0086] Reference Figure 7 and Figure 8 When the number of metal shafts 9 on the first transport platform 51 reaches the first saturated number, the first opening cylinder 74 drives the first support block 54 away from the first transport platform 51, and at the same time, the lifting plate 72 moves downward so that the first shaft storage box 7 has a clearance space for the next metal shaft 9 to enter. At this time, the metal shaft 9 on the first support block 54 falls on the top of the cavity in the first shaft storage box 7, and finally the first opening cylinder 74 drives the first support block 54 to move to close the first drop opening 53.

[0087] When the number of metal shafts 9 on the first transport platform 51 reaches the first compensation number, the first opening cylinder 74 drives the first support block 54 away from the first transport platform 51, and then the lifting plate 72 moves upward. At this time, the metal shafts 9 in the first shaft storage box 7 rise and abut against the first support block 54. Then, the first opening cylinder 74 drives the first support block 54 to move toward the first transport platform 51, thereby refilling the first drop port 53 and fixing the metal shaft 9 in the first sliding groove 511.

[0088] Among them, the length of the first dropping port 53 is slightly greater than the length of the metal shaft 9, so that the metal shaft 9 drops into the first shaft storage box 7 individually. And the position of the first dropping port 53 can be selected according to the length of the metal shaft 9, the first compensation quantity and the first saturation quantity, which not only ensures that the metal shaft 9 can drop into the first shaft storage box 7, but also ensures that when the metal shaft 9 in the first shaft storage box 7 enters the first transportation table 51, the metal shaft 9 does not interfere with the metal shaft 9 on the original first transportation table 51, that is, the distance between the first dropping port 53 and the first friction mechanism 101 is greater than the product of the first saturation quantity and the length of the metal shaft 9.

[0089] Referring to Figure 9 , an installation groove 121 for placing the accommodation bin 2 is formed on the inclined plate 12. The accommodation bin 2 is detachably connected to the inclined plate 12 by placing the accommodation bin 2 in the installation groove 121. The accommodation bin 2 includes a first side plate 21, a second side plate 22, a bottom plate 25, a first insertion plate 23 and a second insertion plate 24. The first side plate 21 and the second side plate 22 are arranged opposite to and parallel to each other. The first insertion plate 23 and the second insertion plate 24 are arranged opposite to and parallel to each other. First slots 26 for the first insertion plate 23 to slide and insert and second slots 27 for the second insertion plate 24 to slide and insert are formed on both the first side plate 21 and the second side plate 22.

[0090] Referring to Figure 2 , a preparation groove 17 is arranged on the installation table 1. The preparation groove 17 is used for the prepared accommodation bin 2. When the metal shafts 9 in the accommodation bin 2 on the inclined plate 12 are used up, the accommodation bin 2 in the preparation groove 17 is placed in the installation groove 121 on the inclined plate 12 for continuous use. A fixing groove 171 for placing the accommodation bin 2 is formed at the bottom of the preparation groove 17. When the accommodation bin 2 in the preparation groove 17 is placed on the inclined plate 12, the first insertion plate 23 and the second insertion plate 24 can be removed so that the metal shafts 9 in the accommodation bin 2 roll out of the accommodation bin 2.

[0091] Based on the above automatic feeding device, an embodiment of the present invention provides an automatic feeding detection control method, including:

[0092] S101: Obtain the end processing position information of the metal shaft 9. The end processing position information includes left processing position information and right processing position information;

[0093] Above the sliding channel 4, a detection device is provided. Inside the detection device, a camera mechanism for photographing the metal shaft 9 is provided. When the metal shaft 9 slides within the sliding channel 4 or is blocked within the sliding channel 4 by the first blocking member, the image information of the metal shaft 9 can be obtained through the camera mechanism. Then, through the method of pattern recognition, the position of the processing end 91 of the metal shaft 9, that is, the end processing position information of the metal shaft 9, can be judged, so as to judge whether to polish the metal shaft 9 through the first friction mechanism 101 or through the second friction mechanism 102. Among them, the left processing position information and the right processing position information do not specifically refer to the left and right orientations of the metal shaft 9. "Left" and "right" are only a preset name for the position of the processing end 91.

[0094] S102: Generate second blocking control information according to the corresponding relationship between the preset end processing position information and the second blocking control information;

[0095] After judging the end processing position, the second blocking control information can be obtained through the corresponding relationship between the end processing position information and the second blocking control information. For example, when the left processing position information is obtained, the second blocking control information is sent; when the right processing position information is obtained, the second blocking control information is not sent.

[0096] S103: Send out the second blocking control information for controlling the operation of the second blocking component 44;

[0097] Whether the second blocking component 44 blocks the metal shaft 9 is controlled through the second blocking control information, so as to transport the metal shaft 9 to the corresponding first transport table 51 or the second transport table 62 by adjusting the sliding-out speed of the metal shaft 9.

[0098] S104: Obtain the pushing control information according to the corresponding relationship between the preset end processing position information and the pushing control information;

[0099] S105: Send out the pushing control information for controlling the first pushing driving member 52 or the second pushing driving member 61 to push the metal shaft 9.

[0100] The pushing control information is used to push the metal shaft 9, so as to push the metal shaft 9 into the first friction mechanism 101 or the second friction mechanism 102.

[0101] In this embodiment, since the radius difference between the processing end 91 of the metal shaft 9 and the other end of the metal shaft 9 is small, and due to the existence of the tapered portion 92, the accuracy of the recognition result is poor by using the method of pattern recognition for the processing end 91 of the metal shaft 9. In this embodiment, another acquisition direction of the end processing position information is also disclosed, which is specifically as follows:

[0102] Refer to Figure 10, S1011: Obtain the moving image information of the metal shaft 9 within the sliding channel 4;

[0103] In this embodiment, since the metal shaft 9 is not completely cylindrical, and the radius of the machining end 91 of the metal shaft 9 is greater than the radius of the other end of the metal shaft 9, when the metal shaft 9 slides downward within the sliding channel 4, the metal shaft 9 does not slide straight downward, but will have a certain degree of deflection, and the deflection direction of the metal shaft 9 during sliding is related to the position of the machining end 91 of the metal shaft 9.

[0104] S1012: According to the moving image information of the metal shaft 9, obtain the moving offset direction information of the metal shaft 9;

[0105] According to the corresponding relationship between the end machining position information and the moving offset direction information, obtain the end machining position information of the metal shaft 9.

[0106] Based on the characteristic that the metal shaft 9 will deflect, in another embodiment, it is also possible to judge the end machining position information of the metal shaft 9 by judging the landing position of the metal shaft 9, specifically as follows

[0107] When the first blocking member temporarily blocks the metal shaft 9 within the sliding channel 4, by judging the relative position relationship between the metal shaft 9 and the first blocking plate 432, the deflection situation of the metal shaft 9 during sliding can be judged, and thus the end machining position of the metal shaft 9 can be judged. Among them, the relative position between the metal shaft 9 and the first blocking plate 432 is also obtained by shooting with a camera mechanism.

[0108] When the number of metal shafts 9 on the first transport table 51 is different, the pushing stroke of the first pushing driving member 52 is also different. In this embodiment, a control method for the first pushing driving member is also disclosed:

[0109] S1041: Obtain the first quantity, where the first quantity represents the number of metal shafts 9 on the first transport table 51;

[0110] S1042: According to the corresponding relationship between the first quantity and the first pushing stroke information of the first pushing driving member 52, obtain the first pushing stroke information, and the first pushing stroke information includes the first stroke information for the workpiece to be machined and the first stroke information for the machining station;

[0111] The stroke of the first workpiece to be processed station refers to the pushing stroke corresponding to the first pushing driving member 52 when the metal shaft 9 just dropped on the first transport table 51 is pushed to the workpiece to be processed station. The workpiece to be processed station refers to pushing the metal shaft 9 dropped from the sliding channel 4 towards the position where the previous metal shaft 9 is located. At this time, the pushed metal shaft 9 will not push the metal shaft 9 on the original first transport table 51, but only to push the metal shaft 9 forward a certain distance from its dropping point, so that the metal shaft 9 dropped from the sliding channel 4 later is not likely to fall above the metal shaft 9, thus making it less likely for the two metal shafts 9 to interfere with each other.

[0112] The processing station refers to the situation where the first friction mechanism 101 has completed the grinding of the metal shaft 9 and needs to grind the next metal shaft 9. At this time, it is necessary to push the metal shaft 9 on the first transport table 51 to make the new metal shaft 9 enter the first friction mechanism 101. The first processing station stroke refers to the stroke corresponding to the first pushing driving member 52 when pushing the next metal shaft 9 into the first friction mechanism 101.

[0113] Among them, both the first workpiece to be processed station stroke and the first processing station stroke are related to the number of metal shafts 9 on the first transport table 51, and the more metal shafts 9 on the first transport table 51, the smaller the first workpiece to be processed station stroke and the first processing station stroke.

[0114] S103: Obtain the processing time value;

[0115] The processing time value refers to the grinding processing time of the first friction mechanism 101 or the second friction mechanism 102 on the processing end 91 of the metal shaft 9.

[0116] S1044: Determine whether the first processing time value is greater than the preset total processing time value;

[0117] The total processing time refers to the total time required to grind one metal shaft 9.

[0118] S1045: If it is, send a pushing control information for controlling the first pushing driving member 52 to push the metal shaft 9 according to the first processing station stroke information;

[0119] When the first processing time value reaches the preset total processing time value, it means that the first friction mechanism 101 has completed the processing of the current metal shaft 9. At this time, it is necessary to push the subsequent metal shafts 9 into the first friction mechanism 101. When the metal shaft 9 is ejected from the first friction mechanism 101, the first quantity is reduced by one, and when a new metal shaft 9 drops on the first transport table 51, the first quantity is increased by one.

[0120] S1046: If the answer is no, based on the end processing position information, determine whether the metal shaft 9 has rolled onto the first transport table 51. Only when the metal shaft 9 has rolled onto the first transport table 51, send the push control information for controlling the first push cylinder to push the metal shaft 9 according to the first to-be-processed station stroke information.

[0121] The first processing time value has not reached the preset full processing time value, indicating that the grinding time of the first friction mechanism 101 on the metal shaft 9 is insufficient. For example, when two metal shafts 9 in the storage bin 2 consecutively fall onto the first transport table 51, and assuming that when the first metal shaft 9 falls onto the first transport table 51, the first push driving member 52 pushes according to the first processing station stroke, and the first friction mechanism 101 starts to process the metal shaft 9. At this time, when the second metal shaft 9 falls onto the first transport table 51, the first friction mechanism 101 has not completed the grinding of the metal shaft 9. At this time, the first push driving member 52 pushes the metal shaft 9 according to the first to-be-processed station stroke.

[0122] Among them, when it is determined through the end processing position information that the next metal shaft 9 will not fall onto the first transport table 51, the first push driving member 52 does not push the metal shaft 9 according to the first to-be-processed station stroke. And if the processing time value reaches the full processing time value at this time, even if no metal shaft 9 has fallen onto the first transport table 51, the first push driving member 52 also pushes the metal shaft 9 according to the first processing station stroke.

[0123] The push control method of the second push driving member 61 is the same as that of the first push driving member 52, and will not be elaborated in this embodiment.

[0124] Since the lengths of the first transport table 51 and the second transport table 62 are limited, and the number of metal shafts 9 they can accommodate is also limited, in this embodiment, the first shaft storage box 7 and the second shaft storage box 8 are used to buffer the number of metal shafts 9. Taking the first shaft storage box 7 as an example for illustration:

[0125] S201: When the first quantity reaches the preset first saturation quantity;

[0126] The first saturation quantity is a preset value, which can be three or four or other values, and can be specifically determined according to the length value of the first transport table 51. When the first quantity reaches the first saturation quantity, it means that the number of metal shafts 9 on the first transport table 51 is relatively large, and there is a risk that the first transport table 51 cannot continue to accommodate the metal shafts 9.

[0127] S202: Send the first release information, and the first release information is used to control the driving part of the first lifting driving member 71 to move downward so that the metal shaft 9 falls from the bottom of the first dropping port 53 into the first shaft storage box 7;

[0128] At this time, through the mutual cooperation of the first opening cylinder 74 and the first lifting driving member 71, the metal shaft 9 on the first transport table 51 falls into the first shaft storage box 7 to reduce the first quantity.

[0129] S301: When the first quantity reaches the first compensation quantity;

[0130] When the first quantity reaches the first compensation quantity, it indicates that the metal shaft 9 needs to be added to the first transport table 51.

[0131] S302: Send a first compensation message, which is used to control the piston rod of the first lifting driving member 71 to rise so that the metal shaft 9 re-enters the first transport table 51;

[0132] At this time, through the mutual cooperation of the first opening cylinder 74 and the first lifting driving member 71, the metal shaft 9 in the first shaft storage box 7 enters the first transport table 51 to increase the first quantity.

[0133] Due to the limited volumes of the first shaft storage box 7 and the second shaft storage box 8, as the automatic feeding device operates for a long time, there may be a situation where the quantity of the metal shafts 9 in the first shaft storage box 7 or the second shaft storage box 8 is too much or too little. For example, when the automatic feeding device completes 10,000 feedings, there may be 5,060 metal shafts 9 transported to the first transport table 51 and 4,940 metal shafts transported to the second transport table 62. At this time, the first shaft storage box 7 may not be able to continue storing the metal shafts 9. And because it is not convenient to disassemble the first shaft storage box 7 and the second shaft storage box 8, the adjustment of the quantity of the metal shafts 9 inside them is rather troublesome. Therefore, in this embodiment, a method for controlling the quantity of the metal shafts 9 in the first shaft storage box 7 and the second shaft storage box 8 is also disclosed:

[0134] Refer to Figure 2 , S401: Obtain the end machining position information of all the metal shafts 9 in the accommodation bin 2;

[0135] Second detection devices 18 are arranged on the groove walls on both sides of the spare shaft groove. A camera mechanism is arranged inside the second detection devices 18, and both the first side plate 21 and the second side plate 22 are made of transparent materials. The specific material can be transparent plastic or transparent glass. The end images of the metal shafts 9 in the accommodation bin 2 on the spare shaft groove are obtained through the second detection devices 18, so as to judge the end machining position information of all the metal shafts 9 in the accommodation bin 2 by means of image recognition. And the metal shafts 9 in the spare shaft groove are in a static state. The accuracy of image recognition is higher than that of image recognition of the metal shafts 9 in the sliding channel 4. Moreover, the accommodation bin 2 in the spare shaft groove is placed for a longer time, and the image recognition time is also longer. The accuracy can be improved through multiple recognitions and calculations.

[0136] S402: Obtain the quantity of the processing ends 91 corresponding to the first side plate 21 of the accommodation bin 2 and the quantity of the processing ends 91 corresponding to the second side plate 22 of the accommodation bin 2 according to the end processing position information of all the metal shafts 9 in the accommodation bin 2;

[0137] S403: Calculate the first machining allowance value according to the sum of the first quantity and the quantity of the metal shafts 9 in the first shaft storage box 7;

[0138] S404: Calculate the second machining allowance value according to the sum of the second quantity and the quantity of the metal shafts 9 in the second shaft storage box 8;

[0139] A display is provided on the installation platform 1, which is used to display the quantity of the processing ends 91 corresponding to the first side plate 21 and the quantity of the processing ends 91 corresponding to the second side plate 22 of the accommodation bin 2. At the same time, the calculated first machining allowance value and second machining allowance value can also be displayed.

[0140] S405: When the first machining allowance is greater than the second machining allowance;

[0141] If the quantity of the processing ends 91 corresponding to the first side plate 21 is greater than the quantity of the processing ends corresponding to the second side plate 22, a reminder signal for reminding the staff to make the first side plate 21 correspond to the second pushing assembly 6 is sent. If the quantity of the processing ends 91 corresponding to the first side plate 21 is less than the quantity of the processing ends 91 corresponding to the second side plate 22, a reminder signal for reminding the staff to make the first side plate 21 correspond to the first pushing assembly 5 is sent;

[0142] When the first machining allowance is greater than the second machining allowance, it means that the remaining workload of the first friction mechanism 101 is greater than the remaining workload of the second friction mechanism 102. At this time, by changing the placement method of the accommodation bin 2, according to the quantity of the processing ends 91 corresponding to the first side plate 21 and the quantity of the processing ends 91 corresponding to the second side plate 22, it is judged that the first side plate 21 or the second side plate 22 corresponds to the first friction mechanism 101, that is, by adjusting the placement method of the accommodation bin 2, the increased workload of the subsequent first friction mechanism 101 is made less than the increased workload of the second friction mechanism 102, so as to reduce the quantity of the metal shafts 9 in the first shaft storage box 7 and increase the quantity of the metal shafts 9 in the second shaft storage box 8.

[0143] S406: When the first machining allowance is less than the second machining allowance;

[0144] If the number of processing ends 91 corresponding to the first side plate 21 is greater than the number of processing ends corresponding to the second side plate 22, a reminder signal is sent to remind the staff to make the first side plate 21 correspond to the first pushing component 5. If the number of processing ends 91 corresponding to the first side plate 21 is less than the number of processing ends corresponding to the second side plate 22, a reminder signal is sent to remind the staff to make the first side plate 21 correspond to the second pushing component 6.

[0145] Similarly, when the remaining workload of the first friction mechanism 101 is less than the remaining workload of the second friction mechanism 102, the increased workload of the subsequent first friction mechanism 101 can be made greater than the increased workload of the second friction mechanism 102.

[0146] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Any feature disclosed in this specification (including the abstract and drawings), unless specifically described, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically described, each feature is only an example of a series of equivalent or similar features.
