Description
Technical Field
[0001] The present invention relates to the technical field of neatly stacking parts, in particular to a stacking device for automatically stacking parts. Background Art
[0002] The structure of multiple carriers 1 provided by a customer to the workshop is as follows Figure 1 As shown, a plurality of rows of receiving slots 2 are provided on the top surface of each carrier 1 and along its width direction, wherein a part 3 is placed in the receiving slot 2 of each row of receiving slots 2. The structure of the part 3 is as shown in FIG. Figure 1~Figure 2 As shown, the thickness of the part 3 is 1~2mm, a through hole 4 is provided in the part 3, a countersunk hole 5 is provided in the top end of the through hole 4 and is connected to the through hole 4, the diameter of the countersunk hole 5 is larger than the diameter of the through hole 4, and the countersunk hole 5 is coaxial with the through hole 4, the depth of the countersunk hole 5 is 0.6mm, and an oblique cut (6) is provided at one corner of the part 3.
[0003] Since the parts 3 are arranged randomly, the countersunk holes 5 of the parts 3 in some of the accommodating grooves 2 are facing upward [the parts 3 with the countersunk holes 5 facing upward are called positive parts], while the countersunk holes 5 of the parts 3 in other of the accommodating grooves 2 are facing downward [the parts 3 with the countersunk holes 5 facing downward are called negative parts].
[0004] When the workers in the workshop receive a batch of trays 1 loaded with parts 3, the customer requires that the front parts in each tray 1 be neatly stacked together. At the same time, the customer also requires that the back parts in each tray 1 be turned over and then neatly stacked together. The customer also requires that the direction of the bevel cuts (6) of each stacked part 3 be consistent. The state of the stacked parts 3 is as follows: Figure 4 shown.
[0005] The workers in the workshop stack the front parts and back parts in each carrier 1 together in the following way: S1. A worker takes out a carrier plate 1 loaded with a part 3 and places the carrier plate 1 flat on the machine table. S2. The worker first identifies the front part and then takes it out from the corresponding receiving slot 2. After taking it out, the worker puts the front part on the column; S3. After all the front parts in a carrier 1 have been identified, the worker takes out the remaining back parts 3 in the carrier 1 from the corresponding receiving slots 2. After taking them out, the worker flips the back parts 180° and then puts the back parts on the pillars, thus completing the stacking of the front and back parts in a carrier 1. S4. The worker repeats steps S1 to S3 multiple times to stack the front and back parts in all the carriers 1. At this time, there are parts stacked on the column to a certain height, and the countersunk holes 5 of each part 3 are facing upward.
[0006] However, although the worker's operation method can stack the front parts and back parts in the customer's carrier 1 together, in actual operation, the following technical defects are still reflected: I. The customer provided a tray 1 with as many as 200 to 233 parts. After workers identified the front parts, they had to manually place them on the columns. This undoubtedly increased their workload and took a long time to stack all the front parts, resulting in a technical defect of low part stacking efficiency.
[0007] II. After the front parts are stacked, the worker needs to turn over the remaining reverse parts in the carrier 1, and then put the reverse parts on the pillars. The entire operation is done manually, which not only increases the worker's workload, but also takes a long time to stack all the reverse parts, thereby further reducing the efficiency of stacking parts.
[0008] Therefore, there is an urgent need for a stacking device that can greatly reduce the workload of workers and greatly improve the efficiency of stacking parts. Summary of the Invention

[0026] The working method of the present invention is: S1. The worker will provide multiple Figure 1 The carrier plates 1 are shown arranged from front to back on the belt 16 of the belt conveyor 7; S2. Control the belt conveyor 7 to start, and the belt conveyor 7 drives the belt 16 to rotate, and the belt 16 drives the carrier plate 1 thereon to move backward. After the belt conveyor 7 runs for a period of time, the controller controls the belt conveyor 7 to stop. At this time, the first carrier plate 1 is below the vertical screw module A13; S3, stacking the front parts and the back parts in the first carrier 1 together, the specific operation steps are as follows: S31. The controller controls the horizontal screw module A12 to start. The moving part of the horizontal screw module A12 drives the vertical screw module A13, the connecting frame A14, and the nine suction heads A15 to move in a horizontal square. When the nine suction heads A15 are respectively directly above the nine parts in the carrier 1, the controller controls the horizontal screw module A12 to close. S32: Control the vertical screw module A13 to start. The moving part of the vertical screw module A13 drives the connecting frame A14 and the nine suction heads A15 to move downward synchronously. The nine suction heads A15 move toward the nine parts respectively. When the nine suction heads A15 respectively contact the top surfaces of the nine parts, the controller controls the vertical screw module A13 to close and then controls the nine vacuum pumps A to start. The vacuum pumps A evacuate the suction heads A15 connected to them. Under negative pressure, the nine parts are respectively fixed to the nine suction heads A15 by suction. S33, controlling the vertical screw module A13 to start, the moving part of the vertical screw module A13 drives the connecting frame A14 and the nine suction heads A15 to move upward synchronously, and the nine suction heads A15 respectively drive the nine parts to move upward, thereby lifting the nine parts; S45. After the nine parts are lifted, the horizontal screw module A12 is controlled to start. The moving part of the horizontal screw module A12 drives the vertical screw module A13, the connecting frame A14 and the nine suction heads A15 to move synchronously to the left, thereby driving the nine parts to move synchronously to the left. When the movement of the nine parts is directly above the CCD lens 8, the controller controls the horizontal screw module A12 to close. At this time, the CCD lens 8 identifies the bottom surfaces of the nine parts. If the CCD lens 8 identifies that there is a countersunk hole 5 on the bottom surface of the part, the CCD lens 8 determines that the identified part is a reverse part, and the CCD lens 8 transmits the position of the reverse part to the controller; if the CCD lens 8 identifies that there is no countersunk hole 5 on the bottom surface of the part, the CCD lens 8 determines that the identified part is a front part, and the CCD lens 8 transmits the position of the front zero to the controller; S35. Control the transverse screw module A12 to start. The moving portion of the transverse screw module A12 drives the vertical screw module A13, the connecting frame A14, and the nine suction heads A15 to move synchronously to the left, thereby driving the front and back parts to move synchronously to the left. When the transverse screw module A12 runs for a set time, the controller controls the transverse screw module A12 to close. At this time, the nine parts are respectively located directly above the grooves 28 of the flip assembly 9. S36: Control the vertical screw module A13 to start. The moving portion of the vertical screw module A13 drives the connecting frame A14 and the nine suction heads A15 to move downward synchronously, thereby driving the nine parts downward. When the nine parts respectively enter the respective grooves 28 of the flip assembly 9, the controller controls the vertical screw module A13 to close. Then, the controller controls the vacuum pump A corresponding to the reverse part to close. At this time, the reverse part falls into the corresponding groove 28, thereby temporarily retaining the reverse part in the groove 28 of the flip assembly 9. S37, controlling the vertical screw module A13 to start, the moving part of the vertical screw module A13 drives the connecting frame A14 and the nine suction heads A15 to move upward synchronously, thereby driving the front part to move upward, thereby lifting the front part; When the front part is lifted, the controller controls the transverse screw module A12 to start, and the moving part of the transverse screw module A12 drives the vertical screw module A13, the connecting frame A14 and the nine suction heads A15 to move synchronously to the left, thereby driving the front part to move to the left. When the transverse screw module A12 runs for a set time, the controller controls the transverse screw module A12 to close. At this time, the front part is directly above the step groove 38 of the turnover assembly 10; Then the vertical screw module A13 is controlled to start, and the moving part of the vertical screw module A13 drives the connecting frame A14 and the nine suction heads A15 to move downward synchronously. When the front part enters the step groove 38 of the turnover assembly 10, the vacuum pump A corresponding to the front part is controlled to be turned off. At this time, the front part is temporarily placed on the shoulder of the step groove 38; Then the vertical screw module A13 is controlled to start, and the moving part of the vertical screw module A13 drives the connecting frame A14 and the nine suction heads A15 to move upward synchronously, so that the suction heads A15 move away from the step groove 38; S38, flip the reverse part temporarily retained in step S36: control the servo motor 35 of the flipping assembly 9 to start, the servo motor 35 drives the rotating shaft 24 to rotate counterclockwise, the rotating shaft 24 drives the connecting plate 25 to rotate counterclockwise, the connecting plate 25 drives the supporting plate 26 and the strip plate 27 to rotate counterclockwise synchronously, and then drives the movable slider 30, the roller 33 and the reverse part in the strip plate 27 to rotate counterclockwise synchronously. During the rotation process, the roller 33 gradually disengages from the right inclined surface 20 of the right side plate 19. After disengagement, under the elastic restoring force of the spring 34, the top part of the clamp 31 clamps and fixes the reverse part in the groove 28. As the reverse part continues to rotate, when the reverse part rotates 107°, the controller controls the servo motor 35 to turn off. At this time, the roller 33 presses against the left inclined surface 23 of the left side plate 22. Figure 17 As shown, the movable slider 30 drives the chuck 31 to move away from the reverse part, and the chuck 31 no longer clamps the reverse part. The reverse part falls onto the shoulder of the corresponding step groove 38 under its own gravity. At this time, a part is placed in each of the nine step grooves 38 of the hollow rotating table 37, and the countersunk holes 5 of the nine parts are all facing upwards, and the directions of the bevel cuts 6 of the nine parts are inconsistent, as shown in FIG. Figure 18 As shown; S39: The main motor 36 of the turnover assembly 10 is started, and the main motor 36 drives the hollow rotating table 37 to rotate, and the hollow rotating table 37 drives the nine parts to rotate synchronously. After the nine parts rotate 180 degrees on the horizontal plane, the controller controls the main motor 36 to be turned off. At this time, the nine parts are respectively directly under the nine suction heads C46, and the nine parts are respectively directly under the nine lifting plates 51 of the adjustment assembly 47; S40, the piston rod of the lifting cylinder 48 of the control adjustment component 47 extends upward, the piston rod drives the frame 49 to move upward, the frame 49 drives nine stepper motors 50 and nine lifting plates 51 to move upward synchronously, the nine lifting plates 51 respectively pass through the nine step grooves 38 upward, and lift the parts in the step grooves 38; the controller controls the stepper motors 50 corresponding to the parts with inconsistent directions to start, the stepper motors 50 drive the lifting plates 51 to rotate, and the lifting plates 51 drive the parts to rotate synchronously until the directions of the bevel cuts 6 of the nine parts are consistent, as shown in FIG. Figure 19 As shown; S41. Control the vertical screw module C44 to start. The moving portion of the vertical screw module C44 drives the connecting frame C45 and each suction head C46 to move downward synchronously. The nine suction heads C46 move toward the nine parts respectively. When the bottom surfaces of the nine suction heads C46 respectively contact the top surfaces of the nine parts, the vertical screw module C44 is controlled to close. Then, the vacuum pump C connected to the nine suction heads C46 is controlled to start, and the vacuum pump C draws a vacuum on the suction heads C46. Under negative pressure, the nine parts are respectively adsorbed on the nine suction heads C46. Then, the vertical screw module C44 is controlled to start, and the moving part of the vertical screw module C44 drives the connecting frame C45 and the nine suction heads C46 to move upward synchronously, thereby lifting the nine parts. S42. After the nine parts are lifted, the horizontal screw module C43 is controlled to start, and the moving part of the horizontal screw module C43 drives the connecting frame C45 and the suction head C46 to move synchronously to the left, thereby driving the nine parts to move synchronously to the left. When the nine parts move to the top of the nine columns 40 of the material receiving assembly 11, the horizontal screw module C43 is controlled to close; then the vertical screw module C44 is controlled to start, and the moving part of the vertical screw module C44 drives the connecting frame C45 and the nine suction heads C46 to move downward synchronously, thereby driving the nine parts to move toward the nine columns 40 respectively. When the nine parts are respectively sleeved on the nine columns 40, the nine vacuum pumps C are controlled to close. At this time, the nine parts are respectively sleeved on the nine columns 40; S43. Repeat steps S31 to S42 multiple times to stack the front and back parts in the first carrier 1 together. When the stacking is complete, the worker removes the parts neatly stacked on the pillars 40. S4. The worker repeats steps S1 to S3 for several times to stack the front and back parts of all the carriers 1 together, and also ensures that the countersunk holes 5 of each part stacked on the column 40 are facing upward.
[0027] Among them, it can be seen from steps S1 to S4 that the stacking device can stack the parts in the carrier 1 in rows on the column 40 only through the linkage cooperation of the horizontal screw module A12, the vertical screw module A13, the flip assembly 9, the adjustment assembly 47, the turnover assembly 10, the horizontal screw module C43, and the vertical screw module C44, and can also ensure that the countersunk holes 5 of the parts stacked on the column 40 are all facing upward.
[0028] It can be seen from this that compared with the manual stacking method in the workshop, this stacking device does not require workers to first find the front parts and then put the front parts on the column 40, nor does it require workers to turn over the back parts and then put them on the column 40. Instead, it realizes the continuous and automatic stacking of parts in the carrier 1, which not only greatly reduces the work intensity of the workers, but also shortens the stacking time of parts, thereby greatly improving the stacking efficiency of parts.
