Description

Technical Field

[0001] The utility model belongs to the technical field of ultrasonic cleaning machines, and more specifically, relates to a discharging device for ultrasonic cleaning machines. Background Art

[0002] In powder metallurgy production, due to the influence of the molding process and the metalworking fluid and other grease liquids used in the processing process, the surface of the finished powder metallurgy workpiece will be attached with oil, cutting chips, dust and other impurities, which are difficult to completely remove even after the burrs are removed. Because powder metallurgy workpieces involve many special-shaped structural parts, manual cleaning is difficult to clean the inside of the special-shaped structural parts and cannot meet the cleaning requirements. Therefore, ultrasonic cleaning machines or ultrasonic cleaning lines are now mostly used to clean the powder metallurgy workpieces placed in the cleaning frame; however, when a large number of powder metallurgy workpieces are ultrasonically cleaned and dried and transported by mesh belt conveyors, When it reaches the discharge port, due to the bottom plate frame at the bottom of the cleaning frame, the workpieces cannot all fall into the collection box at the discharge port with the mesh belt conveyor. It is often necessary to manually take out the powder metallurgy workpieces from the cleaning frame one by one and align and stack them in the collection box, which is time-consuming and labor-intensive. In the process of manually grabbing the workpieces, the workpieces are prone to fall and be damaged due to failure to grasp the workpieces tightly, resulting in problems affecting the discharge efficiency and workpiece quality. In addition, manual grabbing will affect the cleanliness of the powder metallurgy workpieces and easily cause secondary pollution, thereby affecting the quality of the powder metallurgy workpieces, resulting in low discharge efficiency, high labor intensity and poor workpiece quality.

[0028] The utility model has a high overall automation degree, and integrates multiple functions such as automatic discharging and conveying, automatic removal of the bottom plate 6 of the cleaning frame 5, automatic positioning and discharging, and automatic loading of all workpieces at one time, so that all workpieces can be automatically discharged into the collection box 4 at one time, accurately and quickly, without the need for manual workpiece removal from the cleaning frame 5 one by one and stacking them in the collection box 4, which saves time and effort, and at the same time, avoids secondary contamination of the workpiece due to manual grasping of the workpiece, or damage to the workpiece and reduced discharging speed due to manual failure to grasp the workpiece tightly, and has the advantages of high discharging efficiency, good workpiece quality and low labor intensity as a whole.

[0029] Please refer to Figures 1 to 8 As shown, a discharging device for an ultrasonic cleaning machine comprises a frame 1, a mesh belt conveyor 2 is installed on the frame 1, a cleaning frame 5 for placing workpieces is arranged on the mesh belt conveyor 2; the cleaning frame 5 has an open bottom, and a bottom plate 6 for supporting the bottom of the workpiece is inserted and slidably inserted at the lower end; a plate taking hole 7 for the bottom plate 6 to slide out of the cleaning frame 5 is opened on one side of the cleaning frame 5; a discharging track 3 and a collecting box 4 are arranged in sequence along the conveying direction at the outer side of the output end of the mesh belt conveyor 2; the discharging track 3 is arranged downwardly in a direction close to the collecting box 4, and is equipped with an automatic tool for automatically taking out and recovering the bottom plate 6 Movable plate mechanism; the output end of the discharging track 3 is rotatably connected to a discharge table 8 whose upper end surface is flush with its upper end inclined surface; the discharge table 8 is provided with a discharge hole 19 for discharging all workpieces in the cleaning frame 5 and an automatic opening and closing door for sealing the discharge hole 19; a blocking plate 9 is installed on the discharge table 8 to block the cleaning frame 5 to the discharge hole 19; a pressure sensor is connected to the blocking plate 9; the frame 1 is provided with a first driving mechanism for driving the discharge table 8 to rotate to the upper end parallel to the upper end of the collecting box 4; a second driving mechanism for driving the collecting box 4 to move to the position directly below the discharge hole 19 is provided on one side of the frame 1.

[0030] From the above description, it can be known that after the powder metallurgy workpiece is cleaned and dried by the ultrasonic cleaning machine, the workpiece is transported to the top of the discharge track 3 by the mesh belt conveyor 2 along with the cleaning frame 5. First, through the discharge track 3, since the discharge track 3 is inclined downward in the direction away from the mesh belt conveyor 2, under the action of gravity, the cleaning frame 5 containing the workpiece automatically tilts and slides downward on the discharge track 3, which plays a role in the preliminary automatic transportation of the workpiece and the cleaning frame 5; before the workpiece slides to the lower section of the discharge track 3, the bottom plate 6 is automatically taken out from the cleaning frame 5 through the plate taking hole 7 through the automatic plate taking mechanism and the plate taking hole 7 and recycled for the next use. Since the bottom of the cleaning frame 5 is an open end, the bottom of all the workpieces in the cleaning frame 5 falls to contact with the upper end inclined surface of the discharge track 3, which plays a role in automatically taking out the bottom plate 6 in the cleaning frame 5;

[0031] When the cleaning frame 5 of the removed bottom plate 6 slides out of the output end at the bottom of the discharge track 3, it passes through the unloading platform 8 and the blocking plate 9. Since the upper end surface of the unloading platform 8 is flush with the upper end inclined surface of the unloading track 3, under the action of gravity, the cleaning frame 5 with the removed bottom plate 6 and the workpiece automatically slides downward on the unloading platform 8 until the cleaning frame 5 slides down to the blocking plate 9, and the blocking plate 9 is used to stop the cleaning frame 5 at the unloading position of the unloading platform 8, that is, the unloading hole 19 and the automatic opening and closing door, to prevent the cleaning frame 5 from sliding out of the range of the unloading hole 19, thereby playing the role of automatic secondary transportation and preliminary positioning of the cleaning frame 5 loaded with the workpiece; then, through the pressure sensor and the first driving mechanism, the pressure sensor detects a pressure signal of the cleaning frame 5 sliding down to the blocking plate 9 on the unloading platform 8, and sends the pressure signal to the external control system, and the external control system controls the first driving mechanism to start, and the first driving mechanism drives the unloading platform 8 to rotate to be parallel to the upper end of the collecting box 4, thereby playing the role of secondary positioning of the workpiece and the cleaning frame 5;

[0032] Afterwards, through the second driving mechanism, the collection box 4, the discharge hole 19 and the automatic opening and closing door, the second driving mechanism is started first, and the second driving mechanism drives the collection box 4 to move to the bottom of the discharge hole 19, and then the automatic opening and closing door is started. The automatic opening and closing door opens, and under the action of gravity, all the workpieces in the cleaning frame 5 fall into the collection box 4 through the discharge hole 19 at the same time. Afterwards, the second driving mechanism drives the collection box 4 filled with workpieces to reset in the direction away from the discharge hole 19, which plays the role of discharging all the workpieces in the cleaning frame 5 at one time; finally, the empty cleaning frame 5 is moved out of the discharge table 8 for recycling by an external manipulator or manually, so that it can be placed in the ultrasonic cleaning machine for reuse next time.

[0033] Furthermore, the discharge track 3 includes a group of upper transmission rollers 10 and lower transmission rollers 11 with the same diameter and arranged at equal intervals. Both ends of the upper transmission rollers 10 and both ends of the lower transmission rollers 11 are rotatably connected to both sides of the frame 1; the gaps between adjacent lower transmission rollers 11 are provided with long plates 12 for supporting the workpiece and the bottom of the cleaning frame 5, and both ends of the long plates 12 are fixedly connected to both sides of the frame 1, and the automatic plate taking mechanism is located outside the side of the upper transmission roller 10 close to the long plates 12. The upper transmission rollers 10, the lower transmission rollers 11 and the long plates 12 jointly form a conveying surface for the cleaning frame 5 to slide down toward the unloading table 8, and the angle between the conveying surface and the horizontal plane is in the range of 6° to 10°. Both sides of the cleaning frame 5 are connected with slide rails 13, and both sides of the upper transmission rollers 10 and both sides of the lower transmission rollers 11 are provided with sliding grooves 14 for the slide rails 13 to slide along the length direction of the discharge track 3.

[0034] From the above description, it can be known that when the workpiece is transported to the discharge track 3 by the mesh belt conveyor 2 along with the cleaning frame 5, under the action of gravity, the cleaning frame 5 enters the conveying surface, and the cleaning frame 5 is first slid and transported in the direction close to the lower transmission roller 11 through a group of upper transmission rollers 10. Without using additional driving force, it can ensure that the cleaning frame 5 slides down smoothly while reducing the friction between the upper section of the discharge track 3 and the bottom of the cleaning frame 5. When the cleaning frame 5 is about to slide down and be transported to the lower transmission roller 11 and the long board 12, the automatic board taking mechanism automatically takes out the bottom plate 6 from the cleaning frame 5 through the board taking hole 7 and recycles it. The cleaning frame 5 without the bottom plate 6 slides down to the long board 12 and the lower transmission roller 11, and the workpiece without the bottom plate 6 is supported by the long board 12 and the lower transmission roller 11. The long board 12 avoids In order to prevent the bottom part of the workpiece from being stuck in the gap between adjacent lower transmission rollers 11, the friction between the lower section of the discharge track 3 and the cleaning frame 5 and the bottom of the workpiece is reduced through the rotation of the lower transmission roller 11, while the cleaning frame 5 without the bottom plate 6 and the workpiece in the cleaning frame 5 are smoothly slid and conveyed toward the unloading platform 8, thereby realizing the automatic secondary discharge conveying and preliminary positioning of the cleaning frame 5 containing the workpiece; by setting the conveying surface to have an angle range of 6° to 10° with the horizontal plane, it is avoided that the cleaning frame 5 has a large impact force on the blocking plate 9 due to the large sliding speed of the cleaning frame 5, causing the workpiece to fly out of the cleaning frame 5 or the cleaning frame 5 and the workpiece to be damaged by collision, thereby further ensuring the quality of the workpiece and improving the discharge efficiency.

[0035] Furthermore, a partition 15 is detachably installed in the cleaning frame 5, and a plurality of limit holes 16 are provided on the partition 15 for the workpieces to be inserted. Slide grooves 17 are provided on both inner sides of the long sides of the cleaning frame 5 close to the discharge track 3. Both sides of the bottom plate 6 are slidably inserted into the slide grooves 17 along the workpiece conveying direction. The front side of the slide groove 17 is connected to the plate taking hole 7. The bottom plate 6 is provided with a group of filtrate grooves 18 for the cleaning liquid to flow out, and the upper and lower grooves of the filtrate grooves 18 are both provided with arc portions.

[0036] As can be seen from the above description, the workpieces are inserted into the limiting holes 16 through the partitions 15 and the limiting holes 16, which plays the role of separating and positioning the multiple workpieces in the cleaning frame 5, and avoiding collisions between the workpieces or tilting of the workpieces during the process of the workpieces sliding downward along the discharge track 3 and the discharge table 8 with the cleaning frame 5, or during the process of the bottom plate 6 being taken out of the cleaning frame 5, thereby affecting the workpiece quality and discharge efficiency, and playing the role of further improving the discharge efficiency and the workpiece quality; since the partition 15 is detachably installed in the cleaning frame 5, when loading workpieces of different models, it is only necessary to remove the partition 15 and replace it with a partition 15 with a corresponding model of limiting holes 16;

[0037] By providing the slide grooves 17 for sliding and plugging on both sides of the bottom plate 6, it is ensured that a part of the bottom plate 6 located in the cleaning frame 5 always slides smoothly along the workpiece conveying direction, and it is avoided that during the process of taking the bottom plate 6 out of the cleaning frame 5, a part of the bottom plate 6 located in the cleaning frame 5 is tilted and the supporting force of the bottom plate 6 on the bottom of the workpiece is affected, which plays a role in further ensuring the good quality of the workpiece; arc portions are provided at the upper and lower notches of the filtrate groove 18 for the outflow of the cleaning liquid, so as to avoid the sharp edge of the upper notch of the filtrate groove 18 colliding with the bottom of the workpiece when the bottom plate 6 is drawn out of the cleaning frame 5, thereby damaging the workpiece, which plays a role in further improving the quality of the workpiece.

[0038] Furthermore, the automatic plate taking mechanism includes a long rod 20 that is against the outside of the front side of the cleaning frame 5 and a group of material taking baffles 21 for preventing the long rod 20 from moving downward along the length of the discharge track 3. A group of material taking baffles 21 are respectively mounted on both sides of the upper section of the discharge track 3, and the plate taking hole 7 is arranged on the front side of the cleaning frame 5. The length of the long rod 20 is greater than the bottom edge length of the front side of the cleaning frame 5; the front side of the bottom plate 6 passes through the plate taking hole 7 and is fixedly connected to the long rod 20. The upper section of the discharge track 3 is provided with a material unloading groove 22 for the long rod 20 and the bottom plate 6 to fall and be recovered. The material unloading groove 22 is located between the sliding grooves 14 of the same group; the distance D between the rear groove wall of the material unloading groove 22 and the front side surface of the material taking baffle 21 is greater than the length L of the bottom plate 6, and is less than or equal to the distance B between the front outer wall of the cleaning frame 5 and the rear inner wall of the cleaning frame 5.

[0039] From the above description, it can be known that when the rear inner wall of the cleaning frame 5 has passed the rear groove wall of the material discharge groove 22 and has slid down to the lower section of the discharge track 3, the two ends of the long rod 20 that is against the front outside of the cleaning frame 5 contact the material fetching baffle 21. As the cleaning frame 5 continues to automatically slide down on the discharge track 3 toward the material discharge platform 8, under the action of the blocking force of the material fetching baffle 21, the long rod 20 and the bottom plate 6 are prevented from continuing to move with the cleaning frame 5. Since the distance D between the rear groove wall of the material discharge groove 22 and the front side surface of the material fetching baffle 21 is greater than the length L of the bottom plate 6, and is less than or equal to the distance B between the front outer wall of the cleaning frame 5 and the rear inner wall of the cleaning frame 5, the material discharge groove 22 is located between the sliding grooves 14 of the same group, that is, the material discharge groove 22 Located between the sliding guide rails 13 on both sides of the cleaning frame 5, there are slide grooves 17, partitions 15 and limit holes 16. During the separation of the bottom plate 6 from the cleaning frame 5, when the bottom plate 6 has not completely left the bottom of the workpiece or has just left the bottom of the workpiece, it is ensured that the workpiece is always stably placed on the bottom plate 6 or stably placed at the lower end of the discharge track 3, avoiding the workpiece without the support of the bottom plate 6 from tilting and falling into the material taking slot. After the long rod 20 drives the bottom plate 6 to completely slide out of the moving cleaning frame 5, the cleaning frame 5 has already completely slid down to the lower section of the discharge track 3. Under the action of gravity, the long rod 20 and the bottom plate 6 fall into the discharge slot 22, and fall to the outside of the discharge track 3 through the discharge slot 22 for collection, thereby automatically taking out and recovering the bottom plate 6.

[0040] Furthermore, a recovery box 23 for recovering the bottom plate 6 is provided below the upper section of the discharge track 3, and rollers and a push rod are respectively provided at the bottom and one side of the recovery box 23, and a feed port 24 communicating with the bottom of the discharge slot 22 is provided at the upper end of the recovery box 23, and a group of guide plates 25 are installed on both sides of the feed port 24, which are inclined upward in a direction away from both sides of the feed port 24, and a buffer plate 26 for placing the bottom plate 6 is provided in the recovery box 23, and a buffer spring 27 is connected between the bottom of the buffer plate 26 and the bottom of the recovery box 23.

[0041] From the above description, it can be seen that after the long rod 20 and the bottom plate 6 fall downward through the unloading slot 22, the long rod 20 and the bottom plate 6 are first adjusted by the guide plate 25, and then enter the recovery box 23 through the feed port 24, which plays the role of automatically collecting the long rod 20 and the bottom plate 6; the long rod 20 and the bottom plate 6 that fall into the recovery box 23 are buffered by the buffer plate 26 and the buffer spring 27, so as to prevent the long rod 20 and the bottom plate 6 from being damaged due to collision with the bottom of the recovery box 23, thereby protecting the long rod 20 and the bottom plate 6; when the discharge is stopped, the hand push rod is manually pushed, and under the rolling action of the roller, the recovery box 23 and the long rod 20 and the bottom plate 6 therein are easily pushed together to be reassembled with the recovered cleaning frame 5.

[0042] Furthermore, the automatic opening and closing door includes a sealing plate 28 for sealing the unloading hole 19 and a translation driving mechanism for driving the sealing plate 28 to slide back and forth along the width direction of the unloading platform 8. Long sliders 29 are fixedly connected on both sides of the sealing plate 28, and a group of sliding grooves 30 for the long sliders 29 to slide along the width direction of the unloading platform 8 are opened in the unloading platform 8; the length direction of the sliding groove 30 is parallel to the width direction of the discharge track 3, and is connected to the opposite side walls of the unloading hole 19; the translation driving mechanism is installed on the frame 1, the sealing plate 28 is fixedly connected with a push block 31, and the driving end of the translation driving mechanism is connected to the push block 31, and a clearance hole 32 for the sealing plate 28 and the long slider 29 to slide to the outside of the unloading platform 8 is opened on one side of the unloading platform 8.

[0043] From the above description, it can be known that after the first driving mechanism drives the unloading platform 8 to rotate to be parallel to the upper end of the collecting box 4, and the second driving mechanism drives the collecting box 4 to move to just below the unloading hole 19, the translation driving mechanism is started, and the driving end of the translation driving mechanism extends or contracts, driving the push block 31 and the sealing plate 28 to move. The sealing plate 28 passes through the long slider 29 in the sliding groove 30 along the width direction of the unloading platform 8 through the give way hole 32 in the direction away from the unloading hole 19 until the sealing plate 28 moves to the unloading hole 19 and is fully opened. All the workpieces in the cleaning frame 5 on the unloading platform 8 fall into the collecting box 4 through the unloading hole 19, which plays the role of automatically discharging all the workpieces into the collecting box 4 at one time; after all the workpieces have fallen into the collecting box 4, and the second driving mechanism drives the collecting box 4 to reset in the direction away from the unloading platform 8, the driving end of the translation driving mechanism is reset, driving the push block 31 and the sealing plate 28 to reset and move to re-seal the unloading hole 19, which plays the role of automatically controlling the opening and closing of the unloading hole 19.

[0044] Furthermore, the second driving mechanism includes a trolley 35, a support plate 36 for stacking multiple layers of workpieces, and a group of screw guide rails 37 for driving the support plate 36 to rise and fall. A sliding plate 39 is fixedly connected between the sliders of a group of screw guide rails 37 and the opposite sides of the support plate 36. Limiting grooves 40 for the sliding plate 39 to rise and fall are provided on the opposite sides of the collection box 4. The support plate 36 slides up and down and is connected in the collection box 4. The trolley 35 slides up and down and is connected with a fixed plate 38. The collection box 4 and the screw guide rails 37 are both installed on the fixed plate 38. A lower lifting cylinder 41 is provided under the unloading table 8. The trolley 35 is provided with a through hole, and a limiting groove 42 is provided at the bottom of the fixed plate 38; the top rod of the lower lifting cylinder 41 passes through the through hole and abuts against the limiting groove 42. The translation driving mechanism is a group of translation cylinders 33; one side of the sealing plate 28 passes through the give way hole 32 and is fixedly connected to the top rod of the translation cylinder 33 through the push block 31.

[0045] As can be seen from the above description, after the first driving mechanism drives the blanking table 8 to rotate until it is parallel to the upper end of the collection box 4, first, the motor of the screw guide rail 37 starts, driving the slider of the screw guide rail 37 to move upward in the direction close to the blanking table 8, thereby driving the sliding plate 39 to move upward in a fixed direction in the limit through groove 40 in the direction close to the blanking table 8, and further driving the support plate 36 to rise to the preset highest position in the collection box 4. Then, the lower lifting cylinder 41 is started, and the ejector rod of the lower lifting cylinder 41 extends, driving the fixing plate 38 to rise, thereby driving the screw guide rail 37 and the collection box 4 to rise together in the direction close to the blanking table 8 until the upper end surface of the collection box 4 contacts the bottom end surface of the blanking table 8. Then, the translation cylinder 33 is started, and the ejector rod of the translation cylinder 33 extends, driving the push block 31 and the sealing plate 28 to move away from the blanking table 8 until the blanking hole 19 is completely opened. After all the workpieces in the cleaning frame 5 fall through the blanking hole 19 onto the support plate 36, the ejector rod of the translation cylinder 33 resets, driving the push block 31 and the sealing plate 28 to reset to seal the blanking hole 19 again. The motor of the screw guide rail 37 rotates in the reverse direction, and the slider of the screw guide rail 37 drives the sliding plate 39 and the support plate 36 to move downward by a preset fixed value to facilitate the loading of all the workpieces in the next cleaning frame 5. After the workpieces in the next cleaning frame 5 fall onto the support plate 36, repeat the above action of the screw guide rail 37 driving the support plate 36 to descend by a preset fixed value until the collection box 4 is full. Replace the next empty collection box 4, and use the trolley 35 to push the collection box 4 filled with workpieces to the next process.

[0046] Further, the second driving mechanism includes a receiving table 43 installed directly below the blanking table 8 and a second conveyor 44 for conveying the collection box 4; the second conveyor 44 is located on the other side of the blanking table 8, and the conveying direction is parallel to the conveying direction of the mesh belt conveyor 2; the receiving table 43 is located on one side of the second conveyor 44, and the upper end surface is flush with the upper conveying end surface of the second conveyor 44. A set of limiting plates 45 for preventing the collection box 4 from shaking are installed on the receiving table 43. The push block 31 is fixedly connected to the bottom of the sealing plate 28 on the side away from the让位孔32. The translation driving mechanism includes a translation cylinder 33 and a return spring 34 connected between the blanking table 8 and the push block 31. The ejector rod of the translation cylinder 33 is connected to an upper lifting cylinder 46, and the ejector rod of the upper lifting cylinder 46 is connected to a push plate 47 for pushing the push block 31 and the collection box 4; the push plate 47 is arranged in a U shape, and the two vertical sections are parallel to the conveying direction of the second conveyor 44; a photoelectric switch 48 for detecting the collection box 4 is installed on the push plate 47.

[0047] It should be noted that there is an unclear "让位孔32" in the original text. You may need to check and correct it according to the actual situation.From the above description, it can be known that after the first driving mechanism drives the unloading platform 8 to rotate to be parallel to the upper end of the collecting box 4, the receiving platform 43 rotates upward together with the unloading platform 8 to be flush with the second conveyor 44, and the second conveyor 44 starts, driving the collecting box 4 to be transported in the direction close to the receiving platform 43 until the collecting box 4 is transported close to the receiving platform 43. The photoelectric switch 48 sends a signal of detecting the presence of the collecting box 4 to the external control system (not shown in the figure, the full text is the same), and the external control system first controls the upper lifting cylinder 46 to start, and the top rod of the upper lifting cylinder 46 is extended, driving the push plate 47 to descend in the direction close to the second conveyor 44 until the collecting box 4 is located between the two vertical sections of the push plate 47, and starts the translation cylinder 33. The top rod of the translation cylinder 33 is extended, driving the push plate 47 to push the collecting box 4 to move on the receiving platform 43, and the push plate 47 is close to the unloading platform 8. The vertical section is used to push the push block 31 toward the clearance hole 32 until the discharge hole 19 is fully opened. At this time, the collection box 4 is located directly below the discharge hole 19. After all the workpieces fall into the collection box 4, the translation cylinder 33 drives the push block 31 and the collection box 4 filled with workpieces to reset and move to the second conveyor 44. The upper lifting cylinder 46 drives the push plate 47 to rise, and the collection box 4 with workpieces is transported to the next process along the second conveyor 44. Under the rebound force of the reset spring 34, the push block 31 and the sealing plate 28 move away from the clearance hole 32 to re-seal the discharge hole 19, thereby automatically controlling the opening and closing of the discharge hole 19. In addition, a limit plate 45 is provided to prevent the collection box 4 from being offset and affecting the discharge accuracy and efficiency during the process of the push plate 47 pushing the collection box 4 to move, thereby further improving the discharge efficiency.

[0048] Furthermore, a buffer pad 49 is connected to the bottom of the collection box 4, a positioning plate 50 is arranged on the buffer pad 49, a groove 51 is opened on the positioning plate 50 for placing the workpiece, and positioning columns 52 are connected to the four sides of the bottom of the collection box 4, and positioning holes 53 are opened on the four sides of the positioning plate 50 for the positioning columns 52 to pass through.

[0049] From the above description, it can be seen that when the collection box 4 is pushed to the bottom of the discharge hole 19 by the push plate 47, the bottom of the fallen workpiece is separated and limited by the groove 51 and the positioning plate 50, so as to avoid the workpieces from colliding with each other during the subsequent transportation, thereby ensuring the accuracy of workpiece discharge and protecting the workpiece; the buffer pad 49 is used to reduce the impact force generated by the workpiece when it falls on the positioning plate 50, thereby further protecting the quality of the workpiece; by providing the positioning column 52 and the positioning hole 53, when the positioning plate 50 is buffered by the buffer pad 49, it is ensured that the positioning plate 50 is slightly moved upward or downward in a directional manner, thereby further ensuring the accuracy of workpiece discharge.

[0050] Furthermore, the first driving mechanism includes a group of telescopic cylinders 53, and support rods 54 are fixedly connected to both sides of the bottom of the unloading platform 8. The unloading hole 19 and the automatic opening and closing door are located between the support rods 54 and the bottom of the discharge track 3. The bottom of the support rod 54 is rotatably connected to the top rod of the telescopic cylinder 53. The bottom of the telescopic cylinder 53 is located below the bottom output end of the discharge track 3, and the bottom of the telescopic cylinder 53 is rotatably connected to the frame 1.

[0051] From the above description, it can be seen that when the pressure sensor detects a pressure signal from the cleaning frame 5 sliding down to the blocking plate 9 on the unloading platform 8, the telescopic cylinder 53 is started, and the top rod of the telescopic cylinder 53 is extended, driving the support rod 54 to rotate the unloading platform 8 upward until the unloading platform 8 rotates to a horizontal plane, that is, the unloading platform 8 is parallel to the upper end surface of the collecting box 4, thereby playing the role of secondary positioning of the workpiece and the cleaning frame 5.
