Description

Technical Field

[0001] This invention belongs to the technical field of automated equipment for mechanical products, specifically relating to a rapid screening machine for the external dimensions of multi-section thin shafts and its usage method. Background Technology

[0002] When multi-section thin shafts are machined on a CNC lathe, products with non-compliant dimensions may be produced. (See attached document.) Figure 1 The multi-section thin shaft 1 to be screened in this invention has the following structure: the middle part of the multi-section thin shaft 1 is a middle diameter reduction section 1.1, the diameter of which is smaller than the diameter of the multi-section thin shaft body; both ends of the multi-section thin shaft 1 are machined with end diameter reduction sections 1.2, the diameter of which is also smaller than the diameter of the multi-section thin shaft body. The goal is to detect whether the middle part of the multi-section thin shaft 1 has a dimensionally acceptable middle diameter reduction section 1.1. Using existing glass disk image recognition systems would require dedicated testing equipment, leading to increased costs and a large footprint, making it unsuitable for flexible production.

[0018] In the above technical solution, each of the second upper air outlet ducts is parallel to the second outlet shaft channel; the second lower air outlet duct is composed of multiple parallel grooves pointing in the outlet shaft direction, and each of the grooves is connected to the second outlet shaft channel.

[0019] In the above technical solution, an auxiliary shaft output component is embedded at the output end of the second output shaft channel to facilitate the subsequent assembly of the qualified multi-section thin shaft.

[0020] In the above technical solution, the discharge mechanism is placed on the work frame, the image support is installed on the work frame, the screening platform is fixedly installed on the image support, and the backlight panel is installed below the screening platform.

[0021] The method of using the multi-section thin shaft rapid dimensional screening machine is as follows:

[0022] The discharge mechanism is activated, arranging the multi-section thin shafts and outputting them to the first output channel of the pre-feeding mechanism. At this time, the lowering cylinder of the pre-feeding mechanism is in a retracted state, and compressed air is blown into the first upper air outlet duct from the first air inlet connector. Then, under the action of the first lower air outlet duct, the multi-section thin shafts in the first output channel are blown into the detection channel of the translation mechanism. Afterwards, the lowering cylinder extends and fixes the subsequent multi-section thin shafts fed into the pre-feeding mechanism. Once the laser detector of the rejection mechanism detects that a multi-section thin shaft has been blown into the detection channel, the image detection unit starts working, capturing images to determine if the multi-section thin shaft is qualified. When the image detection unit detects… When the multi-section thin shaft is in a defective state, the discharge cylinder of the discharge mechanism retracts, the translation plate of the translation mechanism remains stationary, and the compressed air blown from the pre-feeding mechanism blows the defective multi-section thin shaft into the collection box. Then, the discharge cylinder of the discharge mechanism extends forward to return to its initial state, and the pressing cylinder of the pre-feeding mechanism changes from a pressing fixed state to a retracted state, so that the subsequent multi-section thin shafts fixed in the pre-feeding mechanism are no longer fixed and are blown into the detection channel of the translation mechanism under the action of compressed air. When the image detection unit detects that the multi-section thin shaft is in a qualified state, the discharge cylinder of the discharge mechanism remains stationary, and the pressing cylinder of the pre-feeding mechanism... The cylinder remains in a depressed, fixed state, securing the multi-section thin shafts subsequently fed into the pre-feeding mechanism. The push cylinder of the translation mechanism extends, and the translation plate of the translation mechanism slides forward under the action of the push cylinder until the two sides of the detection channel are aligned with the second output shaft channel of the output shaft mechanism and the second auxiliary air duct of the auxiliary blower, respectively. The qualified multi-section thin shafts are blown into the second output shaft channel of the output shaft mechanism by the auxiliary blower. Then, it returns to the initial state, the push cylinder of the translation mechanism retracts, and the translation plate of the translation mechanism slides backward under the action of the push cylinder until the detection channel of the translation mechanism is aligned with the first output shaft channel of the pre-feeding mechanism. The first auxiliary air duct of the translation mechanism is aligned with the second auxiliary air duct of the auxiliary shaft blower. At this time, the compressed air blown out by the auxiliary shaft blower continues to blow the qualified multi-section thin shafts of the shaft outlet mechanism through the second auxiliary air duct. Under the combined action of the compressed air blown in by the second air inlet joint and the compressed air blown out by the auxiliary shaft blower, the qualified multi-section thin shafts are blown out of the shaft outlet mechanism. In addition, after the push cylinder of the translation mechanism retracts to the initial state, the pressing cylinder of the pre-feeding mechanism retracts, so that the multi-section thin shafts subsequently fed into the pre-feeding mechanism are sent into the detection channel of the translation mechanism under the action of compressed air. At this time, one work cycle is completed.

[0023] The advantages and beneficial effects of this invention are as follows:

[0024] (1) The present invention has a simple structure, low cost, and high screening efficiency. It does not require a complex electrical control system and only requires three cylinders to control the equipment. The pressing cylinder can control the multi-section thin shaft to be blown out of the pre-feeding mechanism to prevent the multi-section thin shaft in the translation mechanism from being pushed out of the translation mechanism by the subsequent multi-section thin shaft before it has been fully tested. The pushing cylinder can control the translation mechanism to move back and forth so as to transport the qualified multi-section thin shaft to the blowing port of the auxiliary blowing machine. The control of the discharge cylinder to retract can release the limit on the unqualified multi-section thin shaft, so that the unqualified multi-section thin shaft can be blown into the collection box.

[0025] (2) The present invention provides a shaft output mechanism and an auxiliary shaft output component embedded in the shaft output end of the second shaft output channel of the shaft output mechanism, so as to facilitate the subsequent assembly of the qualified multi-section thin shafts output.

[0026] (3) The present invention also includes a backlight panel to enhance the shooting effect.

[0027] (4) The end of the collection box of the present invention is provided with an upwardly extending baffle to prevent unqualified multi-section thin shafts from flying out of the collection box.

[0028] The pre-feeding mechanism, translation mechanism, rejection mechanism, shaft exit mechanism, auxiliary shaft blower and imaging unit of the present invention work together to quickly achieve a defective product screening efficiency of 0.35S / piece. At the same time, the equipment investment is low, the footprint is small and the structure is compact, and the detection accuracy of shaft parts is high. Attached Figure Description

[0043] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0044] Example 1

[0045] A rapid screening machine for the external dimensions of multi-section thin shafts and its usage method are described below. (See attached document for details on the rapid screening machine for the external dimensions of multi-section thin shafts.) Figure 2 It includes a discharge mechanism 2, a pre-feeding mechanism 3, an image detection unit 4, a translation mechanism 5, an exclusion mechanism 6, a shaft discharge mechanism 7, a work frame 8, a screening platform 9, and an auxiliary shaft blower 10.

[0046] The discharge mechanism 2 is placed on the work frame 8. The pre-feeding mechanism 3 and the auxiliary blower 10 are fixedly installed on the screening platform 9 in parallel along the discharge shaft direction, and the pre-feeding mechanism 3 is aligned with the discharge shaft end of the discharge mechanism 2. The translation mechanism 5 is perpendicular to the discharge shaft direction and is located at the discharge shaft end of the pre-feeding mechanism 3. The rejection mechanism 6 and the discharge shaft mechanism 7 are fixedly installed on the screening platform 9 in parallel along the discharge shaft direction, and the rejection mechanism 6 and the discharge shaft mechanism 7 are located at the discharge shaft end of the translation mechanism 5. In other words, the rejection mechanism 6 and the pre-feeding mechanism 3 are arranged on the same straight line, and the discharge shaft mechanism 7 and the auxiliary blower 10 are arranged on the same straight line.

[0047] See appendix Figure 2-4The pre-feeding mechanism 3 is used to transport the multi-section thin shaft 1 to the translation mechanism 5. The pre-feeding mechanism 3 is composed of a first upper seat 3.1 and a first lower seat 3.2. A first groove 3.31 is provided on the lower surface of the first upper seat 3.1. A second groove 3.32 is provided on the upper surface of the first lower seat 3.2 at the position of the first groove 3.31 on the lower surface of the first upper seat 3.1. The first groove 3.31 and the second groove 3.32 form a transverse through first shaft outlet channel 3.3. On the first upper seat 3.1, first upper air outlet ducts 3.13 are symmetrically arranged on both sides of the first outlet shaft channel 3.3. More specifically, each of the first upper air outlet ducts 3.13 is parallel to the first outlet shaft channel 3.3. On the first lower seat 3.2, first lower air outlet ducts 3.21 are symmetrically arranged on both sides of the first outlet shaft channel 3.3 to guide compressed air towards the outlet shaft direction. More specifically, the first lower air outlet ducts 3.21 are composed of multiple parallel grooves pointing towards the outlet shaft direction, and each groove is connected to the first outlet shaft channel 3.3. The upper end of the first upper seat 3.1 is connected to the first air inlet pipe connector 3.12. The first air inlet pipe connector 3.12 is connected downward to the first upper air outlet duct 3.13. Compressed air enters the first upper air outlet duct 3.13 from the first air inlet pipe connector 3.12, and then, under the action of the first lower air outlet duct 3.21, blows the multi-section thin shaft 1 in the first shaft outlet channel 3.3 to the translation mechanism 5. On the first upper seat 3.1, the first upper seat 3.1 is provided with an auxiliary air outlet 3.4 that is connected to the first upper air outlet duct 3.13 for blowing air to the auxiliary shaft blowing machine 10. The first upper seat 3.1 is provided with a pressing channel (not shown in the figure) perpendicular to the first output shaft channel 3.3, and the pressing channel is connected to the first output shaft channel 3.3. A pressing cylinder 3.11 is provided on the first upper seat 3.1 at the position corresponding to the pressing channel. The piston of the pressing cylinder 3.11 can reciprocate in the pressing channel. When the multi-section thin shaft 1 in the translation mechanism 5 is being detected, the piston of the pressing cylinder 3.11 fixes the multi-section thin shaft 1 that is subsequently sent into the first output shaft channel 3.3, to prevent the multi-section thin shaft 1 in the translation mechanism 5 from being pushed out of the translation mechanism 5 by the subsequent multi-section thin shaft 1 before the detection is completed.

[0048] See appendix Figure 2-4 and attached Figure 10The auxiliary shaft blowing machine 10 is provided with a second auxiliary air blowing duct 10.1. The auxiliary air blowing port 3.4 on the pre-feeding mechanism 3 is connected to the second auxiliary air blowing duct 10.1 provided in the auxiliary shaft blowing machine 10 through an air pipe (not shown in the figure). That is to say, after the compressed air enters the first upper air outlet duct 3.13 from the first air inlet pipe joint 3.12 of the pre-feeding mechanism 3, part of it enters the first shaft outlet channel 3.3, and the other part is blown out from the auxiliary air blowing port 3.4, and then enters the air pipe (not shown in the figure) and is blown into the second auxiliary air blowing duct 10.1 provided in the auxiliary shaft blowing machine 10.

[0049] See appendix Figure 5-6 and attached Figure 10 The translation mechanism 5 is perpendicular to the output shaft direction and is located at the output shaft end of the pre-feeding mechanism 3. The translation mechanism 5 includes a fixed base 5.1, a translation plate 5.2, and a pushing cylinder 5.3. The fixed base 5.1 is fixedly installed on the screening platform 9, and the translation plate 5.2 is slidably installed on the fixed base 5.1. The pushing cylinder 5.3 is connected to the rear of the translation plate 5.2. The translation plate 5.2 can slide back and forth on the fixed base 5.1 under the action of the pushing cylinder 5.3. Furthermore, a translation slide rail 5.11 is provided on the fixed base 5.1, and a sliding protrusion 5.21 is provided under the translation slide rail 5.11. The device slides back and forth in .11; a transversely penetrating detection channel 5.22 is provided inside the translation plate 5.2, and a transversely penetrating first auxiliary air blowing duct 5.24 is arranged parallel to the front of the detection channel 5.22; a symmetrical front-to-back imaging hole 5.23 is provided on the upper surface of the translation plate 5.2 corresponding to the middle part of the multi-section thin shaft 1 in the detection channel 5.22, and the image detection unit 4 is arranged above the imaging hole 5.23. The image detection unit 4 can clearly capture the middle part of the multi-section thin shaft 1 through the imaging hole 5.23, and thus identify whether the size of the middle diameter reduction section 1.1 of the multi-section thin shaft 1 is qualified; in the initial state (see Appendix) Figure 10 The detection channel 5.22 is aligned with the first output shaft channel 3.3 of the pre-feeding mechanism 3, and the first auxiliary air blowing duct 5.24 is aligned with the second auxiliary air blowing duct 10.1 of the auxiliary air blowing machine 10.

[0050] See appendix Figure 5 The image detection unit 4 is mounted on the image bracket 4.3, and a backlight plate 4.2 is also provided to enhance the shooting effect.

[0051] See appendix Figure 7 and attached Figure 10-11The rejection mechanism 6 includes a collection box 6.1, a rejection cylinder 6.2, and a laser detector 6.3. The collection box 6.1, used to collect defective multi-section thin shafts, is horizontally mounted on the screening platform 9. An upwardly extending baffle 6.11 is provided at the tail end of the collection box 6.1 to prevent defective multi-section thin shafts 1 from flying out of the collection box 6.1. The rejection cylinder 6.2 is fixedly mounted on the screening platform 9 perpendicular to the shaft exit direction. The laser detector 6.3 is fixedly mounted on the left side of the piston of the rejection cylinder 6.2. A laser detection hole 6.21 is provided on the piston of the rejection cylinder 6.2 corresponding to the laser emission direction of the laser detector 6.3. In the initial state (see Appendix...), Figure 10 The laser detection hole 6.21 is aligned with the detection channel 5.22 of the translation mechanism 5. The laser detector 6.3 is used to detect whether the multi-section thin shaft 1 has been blown into the detection channel 5.22 of the translation mechanism 5. When the laser detector 6.3 detects that the multi-section thin shaft 1 is located in the detection channel 5.22 of the translation mechanism 5, the image detection unit 4 starts to work, that is, the image detection unit 4 can capture whether the size of the multi-section thin shaft 1 is qualified through the imaging hole 5.23.

[0052] When the image detection unit 4 detects that the multi-section thin shaft 1 is in a defective state (see appendix) Figure 11 The discharge cylinder 6.2 of the discharge mechanism 6 retracts, the translation plate 5.2 of the translation mechanism 5 remains stationary, and the compressed air blown from the pre-feeding mechanism 3 blows the defective multi-section thin shaft 1 into the collection box 6.1. Then, the discharge cylinder 6.2 of the discharge mechanism 6 extends forward and returns to its initial state (see Appendix). Figure 10 The pressing cylinder 3.11 of the pre-feeding mechanism 3 changes from the pressing fixed state to the retracting state, so that the subsequent multi-section thin shaft 1 that was fixed in the pre-feeding mechanism 3 is no longer fixed and is blown into the detection channel 5.22 of the translation mechanism under the action of compressed air.

[0053] See appendix Figure 8-10 The output shaft mechanism 7 is used to output qualified multi-section thin shafts 1. The output shaft mechanism 7 is composed of a second upper seat 7.1 and a second lower seat 7.2. A fourth groove (not shown in the figure) is provided on the lower surface of the second upper seat 7.1. A third groove 7.3 is provided on the upper surface of the second lower seat 7.2 at the position of the fourth groove on the lower surface of the second upper seat 7.1. The third groove 7.3 and the fourth groove form a transversely penetrating second output shaft channel. In the initial state (see Appendix), Figure 10The second outlet shaft channel is aligned with the first auxiliary air duct 5.24 of the translation mechanism 5. On the second upper seat 7.1, second upper air ducts (not shown in the figure) are symmetrically arranged on both sides of the second outlet shaft channel. More specifically, each of the second upper air ducts is parallel to the second outlet shaft channel. On the second lower seat 7.2, second lower air ducts 7.21 for guiding compressed air towards the outlet shaft direction are symmetrically arranged on both sides of the second outlet shaft channel 7.3. More specifically, the second lower air duct 7.21 is composed of multiple parallel grooves pointing in the outlet shaft direction, and each groove is connected to the second outlet shaft channel. The upper end of the second upper seat 7.1 is connected to the second air inlet pipe connector 7.11. The second air inlet pipe connector 7.11 is connected downward to the second upper air outlet duct. Compressed air enters the second upper air outlet duct from the second air inlet pipe connector 7.11. Then, under the action of the second lower air outlet duct 7.21, the multi-section thin shaft 1 in the second shaft outlet channel 7.3 can be blown out.

[0054] In this design, an auxiliary shaft output component 7.4 is embedded at the output end of the second output shaft channel to facilitate subsequent assembly of the qualified multi-section thin shaft 1.

[0055] When the image detection unit 4 detects that the multi-section thin shaft 1 is in a qualified state (see appendix) Figure 12 The discharge cylinder 6.2 of the discharge mechanism 6 remains stationary, and the pressing cylinder 3.11 of the pre-feeding mechanism 3 remains in a fixed pressing state, fixing the multi-section thin shaft 1 subsequently fed into the pre-feeding mechanism 3. The pushing cylinder 5.3 of the translation mechanism 5 extends, and the translation plate 5.2 of the translation mechanism 5 slides forward along the translation slide 5.11 under the action of the pushing cylinder 5.3 until the two sides of the detection channel 5.22 are respectively aligned with the second shaft outlet channel of the shaft outlet mechanism 7 and the second auxiliary air duct 10.1 of the auxiliary shaft blower 10. The qualified multi-section thin shaft 1 is blown into the second shaft outlet channel of the shaft outlet mechanism 7 under the action of the auxiliary shaft blower 10, and then returns to the initial state (see Appendix). Figure 10The push cylinder 5.3 of the translation mechanism 5 retracts, and the translation plate 5.2 of the translation mechanism 5 slides backward along the translation slide 5.11 under the action of the push cylinder 5.3 until the detection channel 5.22 of the translation mechanism 5 is aligned with the first output shaft channel 3.3 of the pre-feeding mechanism 3, and the first auxiliary blowing duct 5.24 of the translation mechanism 5 is aligned with the second auxiliary blowing duct 10.1 of the auxiliary shaft blowing machine 10. At this time, the compressed air blown out by the auxiliary shaft blowing machine 10 continues to be blown towards the output shaft through the second auxiliary blowing duct 10.1. The qualified multi-section thin shaft 1 of mechanism 7 is blown out of the shaft exit mechanism 7 under the combined action of compressed air blown in by the second air inlet pipe joint 7.11 and compressed air blown out by the auxiliary shaft blower 10. In addition, after the push cylinder 5.3 of the translation mechanism 5 retracts to the initial state, the pressing cylinder 3.11 of the pre-feeding mechanism 3 retracts, so that the multi-section thin shaft 1 subsequently fed into the pre-feeding mechanism 3 is sent into the detection channel 5.22 of the translation mechanism 5 under the action of compressed air. At this time, one working cycle is completed.

[0056] The method of using the multi-section thin shaft rapid dimensional screening machine is as follows:

[0057] The discharge mechanism 2 is activated, arranging the multi-section thin shafts 1 and outputting them to the first output channel 3.3 of the pre-feeding mechanism 3. At this time, the pressing cylinder 3.11 of the pre-feeding mechanism 3 is in a retracted state, and compressed air is blown from the first air inlet joint 3.12 into the first upper air outlet duct 3.13. Then, under the action of the first lower air outlet duct 3.21, the multi-section thin shafts 1 in the first output channel 3.3 are blown to the detection channel 5.22 of the translation mechanism 5. After that, the pressing cylinder 3.11 extends and fixes the multi-section thin shafts 1 that are subsequently fed into the pre-feeding mechanism 3. After the laser detector 6.3 of the rejection mechanism 6 detects that the multi-section thin shafts 1 have been blown into the detection channel 5.22, the image detection unit 4 starts to work and takes pictures to see if the dimensions of the multi-section thin shafts 1 are qualified. When the image detection unit 4 detects that the multi-section thin shafts 1 are unqualified (see Appendix), Figure 11 The discharge cylinder 6.2 of the discharge mechanism 6 retracts, the translation plate 5.2 of the translation mechanism 5 remains stationary, and the compressed air blown from the pre-feeding mechanism 3 blows the defective multi-section thin shaft 1 into the collection box 6.1. Then, the discharge cylinder 6.2 of the discharge mechanism 6 extends forward and returns to its initial state (see Appendix). Figure 10 The pressing cylinder 3.11 of the pre-feeding mechanism 3 changes from the pressing and fixing state to the retracting state, so that the subsequent multi-section thin shaft 1, which was fixed in the pre-feeding mechanism 3, is no longer fixed and is blown into the detection channel 5.22 of the translation mechanism under the action of compressed air; when the image detection unit 4 detects that the multi-section thin shaft 1 is in a qualified state (see Appendix) Figure 12The discharge cylinder 6.2 of the discharge mechanism 6 remains stationary, and the pressing cylinder 3.11 of the pre-feeding mechanism 3 remains in a fixed pressing state, fixing the multi-section thin shaft 1 subsequently fed into the pre-feeding mechanism 3. The pushing cylinder 5.3 of the translation mechanism 5 extends, and the translation plate 5.2 of the translation mechanism 5 slides forward along the translation slide 5.11 under the action of the pushing cylinder 5.3 until the two sides of the detection channel 5.22 are respectively aligned with the second shaft outlet channel of the shaft outlet mechanism 7 and the second auxiliary air duct 10.1 of the auxiliary shaft blower 10. The qualified multi-section thin shaft 1 is blown into the second shaft outlet channel of the shaft outlet mechanism 7 under the action of the auxiliary shaft blower 10, and then returns to the initial state (see Appendix). Figure 10 The push cylinder 5.3 of the translation mechanism 5 retracts, and the translation plate 5.2 of the translation mechanism 5 slides backward along the translation slide 5.11 under the action of the push cylinder 5.3 until the detection channel 5.22 of the translation mechanism 5 is aligned with the first output shaft channel 3.3 of the pre-feeding mechanism 3, and the first auxiliary blowing duct 5.24 of the translation mechanism 5 is aligned with the second auxiliary blowing duct 10.1 of the auxiliary shaft blowing machine 10. At this time, the compressed air blown out by the auxiliary shaft blowing machine 10 continues to be blown towards the output shaft through the second auxiliary blowing duct 10.1. The qualified multi-section thin shaft 1 of mechanism 7 is blown out of the shaft exit mechanism 7 under the combined action of compressed air blown in by the second air inlet pipe joint 7.11 and compressed air blown out by the auxiliary shaft blower 10. In addition, after the push cylinder 5.3 of the translation mechanism 5 retracts to the initial state, the pressing cylinder 3.11 of the pre-feeding mechanism 3 retracts, so that the multi-section thin shaft 1 subsequently fed into the pre-feeding mechanism 3 is sent into the detection channel 5.22 of the translation mechanism 5 under the action of compressed air. At this time, one working cycle is completed.

[0058] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0059] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0060] The present invention has been described above by way of example. It should be noted that any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort without departing from the core of the present invention fall within the protection scope of the present invention.

A method of using a multi-section thin shaft rapid dimensional screening machine as described in any one of claims 1-9, characterized in that: The discharge mechanism is activated, arranging the multi-section thin shafts and outputting them to the first output channel of the pre-feeding mechanism. At this time, the lowering cylinder of the pre-feeding mechanism is in a retracted state, and compressed air is blown into the first upper air outlet duct from the first air inlet connector. Then, under the action of the first lower air outlet duct, the multi-section thin shafts in the first output channel are blown into the detection channel of the translation mechanism. Afterwards, the lowering cylinder extends and fixes the subsequent multi-section thin shafts fed into the pre-feeding mechanism. Once the laser detector of the rejection mechanism detects that a multi-section thin shaft has been blown into the detection channel, the image detection unit starts working, capturing images to determine if the multi-section thin shaft is qualified. When the image detection unit detects… When the multi-section thin shaft is in a defective state, the discharge cylinder of the discharge mechanism retracts, the translation plate of the translation mechanism remains stationary, and the compressed air blown from the pre-feeding mechanism blows the defective multi-section thin shaft into the collection box. Then, the discharge cylinder of the discharge mechanism extends forward to return to its initial state, and the pressing cylinder of the pre-feeding mechanism changes from a pressing fixed state to a retracted state, so that the subsequent multi-section thin shafts fixed in the pre-feeding mechanism are no longer fixed and are blown into the detection channel of the translation mechanism under the action of compressed air. When the image detection unit detects that the multi-section thin shaft is in a qualified state, the discharge cylinder of the discharge mechanism remains stationary, and the pressing cylinder of the pre-feeding mechanism... The cylinder remains in a depressed, fixed state, securing the multi-section thin shafts subsequently fed into the pre-feeding mechanism. The push cylinder of the translation mechanism extends, and the translation plate of the translation mechanism slides forward under the action of the push cylinder until the two sides of the detection channel are aligned with the second output shaft channel of the output shaft mechanism and the second auxiliary air duct of the auxiliary blower, respectively. The qualified multi-section thin shafts are blown into the second output shaft channel of the output shaft mechanism by the auxiliary blower. Then, it returns to the initial state, the push cylinder of the translation mechanism retracts, and the translation plate of the translation mechanism slides backward under the action of the push cylinder until the detection channel of the translation mechanism is aligned with the first output shaft channel of the pre-feeding mechanism. The first auxiliary air duct of the translation mechanism is aligned with the second auxiliary air duct of the auxiliary shaft blower. At this time, the compressed air blown out by the auxiliary shaft blower continues to blow the qualified multi-section thin shafts of the shaft outlet mechanism through the second auxiliary air duct. Under the combined action of the compressed air blown in by the second air inlet joint and the compressed air blown out by the auxiliary shaft blower, the qualified multi-section thin shafts are blown out of the shaft outlet mechanism. In addition, after the push cylinder of the translation mechanism retracts to the initial state, the pressing cylinder of the pre-feeding mechanism retracts, so that the multi-section thin shafts subsequently fed into the pre-feeding mechanism are sent into the detection channel of the translation mechanism under the action of compressed air. At this time, one work cycle is completed.
