[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0035] like Figures 1 to 7 As shown, the workpiece packaging machine disclosed in the embodiment of the present application includes: a first conveying component 10, a swinging component 20 and a force-applying component 30. The packaging sleeve is arranged on the first conveying component 10. The swinging component 20 includes a swinging structure 21, a fixed structure 22 and an assembly platform 23. The fixed structure 22 is connected to the swinging structure 21. The fixed structure 22 has a grasping state close to the unloading end of the first conveying component 10 and a placing state close to the assembly platform 23. The force-applying component 30 is arranged toward the assembly platform 23. The workpiece to be packaged is arranged between the assembly platform 23 and the force-applying component 30. The force-applying component 30 has a force-applying state close to the assembly platform 23 and a force-to-apply state away from the assembly platform 23.

[0036] Using the technical solution of this embodiment, the swinging structure 21 swings and drives the fixed structure 22 to the unloading end of the first conveyor assembly 10. After the fixed structure 22 secures the packaging sleeve, the swinging structure 21 continues to swing and drives the fixed structure 22 to the assembly platform 23, where the packaging sleeve is placed. The force-applying assembly 30 applies force to the workpiece to be packaged, pushing it into the packaging sleeve, completing the matching of the workpiece and the packaging sleeve. The technical solution of this embodiment effectively solves the problem of low efficiency in the workpiece packaging process in the prior art.

[0037] The first conveying assembly 10 includes a first conveying section, a second conveying section, a blowing structure, and a baffle structure. After the processed packaging sleeve is demolded, its opening faces the vertical direction and is conveyed by the first conveying section. The loading end of the second conveying section is correspondingly arranged to the unloading end of the first conveying section. The blowing structure is located on the side of the unloading end of the first conveying section away from the second conveying section. By blowing air, the packaging sleeve is caused to fall down. At this time, the opening faces the vertical direction and partially enters the loading end of the second conveying section and is further conveyed by the second conveying section until it is fixed by the fixed structure 22. The baffle structure is located between the first conveying section and the second conveying section. The baffle structure includes a baffle and a third vertical drive unit. The third vertical drive unit drives the baffle to move in the vertical direction. When the number of packaging sleeves is sufficient, the baffle rises to prevent the packaging sleeves from continuing to enter the second conveying section. In order to facilitate the observation of other structures, the second conveying section is not drawn in the accompanying drawings.

[0038] like Figures 1 to 7 As shown, in the technical solution of this embodiment, the swinging structure 21 includes a mounting seat 211, a rotating portion 212, a connecting portion 213 and a swinging portion 214. The rotating portion 212 is rotatably connected to the mounting seat 211, the first end of the connecting portion 213 is rotatably connected to the first end of the rotating portion 212 away from the mounting seat 211, the second end of the connecting portion 213 is rotatably connected to the swinging portion 214, the first end of the swinging portion 214 is rotatably connected to the mounting seat 211, the fixed structure 22 and the swinging portion 214 are rotatably connected on the same rotating shaft, and the connection is located on the side of the connecting portion 213 away from the first end of the swinging portion 214. The rotation of the rotating portion 212 drives the first end of the connecting portion 213 to rotate. The rotation radius of the connection between the rotating portion 212 and the connecting portion 213 is smaller than the distance from the first end of the connecting portion 213 to the second end of the connecting portion 213. Since the second end of the connecting portion 213 is rotatably connected to the swinging portion 214, and the first end of the swinging portion 214 is rotatably connected to the mounting seat 211, the second end of the swinging portion 214 swings, driving the fixed structure 22 to rotate along the Figure 1 The fixed structure 22 reciprocates along the x-axis shown. By properly sizing the various components, the fixed structure 22 can reciprocate between the unloading end of the first conveyor assembly 10 and the assembly platform. By converting rotational motion into oscillating motion using this structure, the overall equipment footprint is reduced. Furthermore, the rotational speed can be set based on the conveying speed of the packaging sleeve and workpiece, achieving periodic continuous operation and stable mechanism operation.

[0039] like Figures 1 to 7As shown, in the technical solution of this embodiment, the fixed structure 22 includes a first vertical drive unit 221 and a fixed unit 222. The fixed unit 222 is connected to the first vertical drive unit 221, and the first vertical drive unit 221 is rotatably connected to the swing unit 214. The fixed unit 222 has a fixed state close to the packaging sleeve and a waiting state away from the packaging sleeve. The first vertical drive unit 221 drives the fixed unit 222 to move in the vertical direction. When the fixed unit 222 moves to the top of the first conveying assembly 10, the first vertical drive unit 221 drives the fixed unit 222 to move downward. After fixing the packaging sleeve, the first vertical drive unit 221 drives the fixed unit 222 to move upward, away from the first conveying assembly 10, to avoid interference between the packaging sleeve and the first conveying assembly 10 during the swinging process. After swinging to the top of the assembly platform 23, the first vertical drive unit 221 drives the fixed unit 222 to descend, placing the fixed unit 222 on the assembly platform 23 to wait for assembly. The first vertical driving portion 221 and the fixing portion 222 are provided to achieve fixed placement of the packaging cover, and avoid interference with other structures during transportation of the packaging cover.

[0040] like Figures 1 to 7 As shown, in the technical solution of this embodiment, the swing structure 21 also includes a first pulley 215, a second pulley 216, and a transmission belt 217. The transmission belt 217 is tensionally connected to the first pulley 215 and the second pulley 216. The first pulley 215 is connected to the fixed structure 22, and the second pulley 216 is rotatably connected to the mounting base 211. The mounting base 211 includes a first shaft, and the second pulley 216 and the first end of the swing portion 214 are both rotatably connected to the first shaft. The swing structure 21 also includes a second shaft, which is fixedly connected to the first pulley 215. The second end of the swing portion 214 is rotatably connected to the second shaft, and the fixed structure 22 is fixedly connected to the second shaft. When the swing portion 214 swings, the first pulley 215 swings with the second end of the swing portion 214, while the second pulley 216 remains in position. The fixed structure 22 always maintains the fixed portion 222 facing downward under the action of gravity. If the fixing structure 22 cannot ensure that the fixing portion 222 faces downward during the swinging motion, the second pulley 216 is rotated to make the transmission belt 217 drive the first pulley 215 to rotate, and the second shaft rotates to drive the fixing structure 22 to rotate, thereby ensuring the direction of the fixing portion 222 and avoiding the problem of the packaging sleeve being unable to be fixed due to the wrong direction of the fixing portion 222.

[0041] like Figures 1 to 7As shown, in the technical solution of this embodiment, the fixing portion 222 includes a plurality of negative pressure portions 2221, and the plurality of negative pressure portions 2221 are arranged toward the assembly platform 23. The negative pressure portion 2221 includes an air suction pipe and a suction cup, and the suction cup is arranged in a vertically downward direction, and the air suction pipe is connected to the suction cup. The plurality of negative pressure portions 2221 fix the packaging sleeve, and the packaging sleeve is not easy to fall off. The negative pressure adsorption method can effectively prevent the packaging sleeve from being deformed, and prevent the workpiece from being difficult to push into the packaging sleeve. In this embodiment, the packaging sleeve is made of lightweight plastic material, which is light in weight and easy to transport.

[0042] like Figures 1 to 7 As shown, in the technical solution of this embodiment, the force-applying assembly 30 includes a first horizontal drive structure 31 and a second horizontal drive structure 32. Both the first and second horizontal drive structures 31 and 32 are positioned toward the assembly platform 23 and are perpendicular to each other. Both the first and second horizontal drive structures 31 and 32 utilize pneumatic cylinders. The first horizontal drive structure 31 is used to push the workpiece into the packaging sleeve, while the second horizontal drive structure 32 is used to push the packaged workpiece into the third conveyor assembly 50. The first and second horizontal drive structures 31 and 32 operate alternately, achieving continuous packaging and unloading, thereby improving packaging efficiency.

[0043] like Figures 1 to 7 As shown, in the technical solution of this embodiment, the workpiece packaging machine also includes a second conveyor assembly 40. The workpiece to be packaged is disposed on the second conveyor assembly 40, and the second conveyor assembly 40 is located between the first horizontal drive structure 31 and the assembly platform 23. The second conveyor assembly 40 includes a first guide rail and a first conveyor belt. The first conveyor belt is disposed within the first guide rail, and the workpiece to be packaged is disposed within the first guide rail. The first conveyor belt rotates to drive the workpiece to move. The first guide rail guides the workpiece to prevent it from deviating from the first conveyor belt during movement. The first horizontal drive structure 31 is located on the side of the first conveyor belt away from the assembly platform 23. When the first horizontal drive structure 31 is activated, it applies a thrust to the workpiece, causing it to enter the packaging sleeve. The length of the first guide rail is less than the length of the first conveyor belt, and the difference between the two is greater than the size of the workpiece along the y-axis, to prevent interference between the workpiece and the first guide rail when the first horizontal drive structure 31 pushes the workpiece.

[0044] like Figures 1 to 7As shown, in the technical solution of this embodiment, the assembly platform 23 includes a base plate 231, a first side plate 232, a clamping portion 233 and a second vertical drive portion 234. The clamping portion 233 is connected to the second vertical drive portion 234. The clamping portion 233 has a clamping state higher than the base plate 231 and a to-be-clamped state lower than the base plate 231. The first side plate 232 is connected to the base plate 231. The first side plate 232 is located on the side of the base plate 231 away from the first horizontal drive structure 31. The fixing portion 222 places the packaging cover on the base plate 231, and the first horizontal driving structure 31 pushes the workpiece into the packaging cover. The setting of the first side plate 232 limits the packaging cover to prevent the packaging cover from falling off the base plate 231 due to the force from the workpiece. The clamping portion 233 includes two jaws. When the clamping portion 233 is opened, the distance between the two jaws in the y-axis direction is greater than the size of the base plate 231 in the y-axis direction. The clamping portion 233 is used to clamp the packaging cover to prevent the position of the packaging cover from being offset, thereby preventing the opening on the packaging cover from being misaligned with the position of the workpiece, which causes the packaging cover to be compressed and deformed during the pushing of the workpiece.

[0045] like Figures 1 to 7 As shown, in the technical solution of this embodiment, the assembly platform 23 also includes a second side plate 235, which is arranged opposite the first side plate 232. The second side plate 235 has a guide hole, the size of which decreases as it approaches and moves away from the first horizontal drive structure 31. The minimum size of the guide hole is larger than the size of the workpiece. The workpiece is pushed into the packaging sleeve along the guide hole. The provision of the guide hole prevents the workpiece from shifting relative to the packaging sleeve during movement, which could cause the packaging sleeve to deform under pressure.

[0046] like Figures 1 to 7 As shown, in the technical solution of this embodiment, the workpiece packaging machine also includes a third conveyor assembly 50, which is located on the side of the assembly platform 23 away from the second horizontal drive structure 32. The packaged workpieces are pushed into the third conveyor assembly 50 by the second horizontal drive structure 32. As the packaged workpieces are continuously pushed in, the previously packaged workpieces are moved along the arrangement direction of the third conveyor assembly 50 under the action of the thrust and conveyed to the subsequent process. The third conveyor assembly 50 includes two guide side plates, each of which includes a guide segment. The spacing between the two guide segments decreases as they move from the assembly platform 23. The guide segments guide the packaged workpieces to ensure that the second horizontal drive structure 32 pushes the workpieces into the third conveyor assembly 50.

[0047] From the above, it can be seen that the workpiece is quickly pushed into the packaging sleeve by the action of the cylinder (first horizontal drive structure 31), and the workpiece is quickly pushed into the packaging sleeve, and the position of the positioning block is adjustable to correspond to a variety of sizes; vacuum adsorption (negative pressure part 2221) is introduced to prevent damage to the packaging sleeve during movement, and the structure is compact and occupies a small space. Initial state: the baffle cylinder (third vertical drive part) rises to push the jacking baffle (baffle) to the highest point, and the packaging sleeve is in place, waiting for the start of work instructions; the packaging sleeve is blown down by the blowing nozzle (blowing structure) and transported to the front of the suction nozzle (negative pressure part 2221), and the suction nozzle sucks air inward to adsorb the workpiece packaging sleeve; the motor starts working, driving the rocker (rotating part 212) to rotate, and the connecting rod (connecting part 213) performs push-pull reciprocating motion, while the large pulley (second pulley 216) is fixed, and the large pulley and the small pulley (first pulley 215) are connected by a belt, so the small pulley The moving cylinder (first vertical drive part 221) performs a left-right circular motion while performing a swinging motion. When the suction nozzle adsorbs the packaging sleeve to the specified position, the moving cylinder extends, and the suction nozzle changes from suction to blowing, and the packaging sleeve is placed on the clamp (clamping part 233); after the lifting cylinder returns to its original position, it transmits a signal to the pushing cylinder (first horizontal drive structure 31) to push the workpiece into the placed packaging sleeve. The signal is then transmitted to the pushing cylinder (second horizontal drive structure 32) to push the finished workpiece with the packaging sleeve onto the conveyor belt (third conveying component 50) for subsequent operation and processing by the mechanism. The method of removing the packaging sleeve in the present application achieves a high frequency of taking out parts and a fast working speed; the workpiece is quickly pushed into the packaging sleeve by the action of the cylinder, and the position of the positioning block is adjustable to correspond to a variety of sizes; vacuum adsorption is introduced to prevent damage to the packaging sleeve during movement, and the structure is compact and occupies a small space. Through the above improvements, the speed problem of workpiece matching for general machines can be solved, and it plays an important role in improving the efficiency of workpiece matching, reducing the matching error rate and avoiding damage to the workpiece packaging sleeve.

To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art can fully understand how to implement the technical solutions of this application.
