Description

Technical Field

[0001] This invention relates to the field of automatic packaging technology, and in particular to an automatic packaging equipment for automotive stamping parts. Background Technology

[0002] After processing, automotive stamping parts are usually wrapped with stretch film to effectively protect the surface of the stamping parts from scratches, collisions and corrosion, ensure the appearance quality of the parts, and wrap the parts into a whole for easy transportation, containerization and handling, reducing the risk of damage and loss. The existing packaging method for stamping parts is to place a pallet with a certain amount of stamping parts on a rotating platform using a forklift, then place the stretch film roll on a lifting device, and then the rotating platform drives the pallet to rotate, while the lifting device slowly moves the stretch film roll upward to achieve the packaging process of the stamping parts.

[0003] However, the current packaging process for automotive stamped parts has the following problems: the existing packaging process does not have an additional useful device to fix the pallet and stamped parts, which causes the pallet and stamped parts to move or slip under the pull of the stretch film during the rotation of the turntable, causing damage to the stamped parts or personal injury. Moreover, the movement of the pallet and stamped parts means that more time is needed to ensure that the automotive stamped parts are properly and fully packaged, thereby reducing the efficiency of the entire packaging process.

[0018] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: This invention uses the upward movement of the screw block to drive the linkage unit, which in turn drives the limiting unit to align and fix the pallet. Then, the pressing unit fixes the stamped parts, thereby ensuring the stability of the stamped parts during the wrapping process and preventing movement of the pallet and stamped parts. This improves the efficiency and quality of stamped parts packaging. When the screw block moves down to reset, the linkage unit drives the limiting unit to release the fixation of the pallet. Thus, the up and down movement of the screw block realizes the alignment, fixation, and release of the pallet, achieving a continuous and efficient integrated operation. This helps reduce the processing time of stamped parts packaging and further improves the processing efficiency of stamped parts packaging.

[0019] The push-pull mechanism of this invention uses the upward movement of the screw block to push the lifting rod to rotate, which in turn pushes the connecting block downward. This, in turn, fixes the tray through the limiting part. After the connecting block is in place, the limiting post moves into the through hole through a return spring to restrict the movement of the connecting block. After the screw block moves upward and disengages from the lifting rod, the limiting part can continue to fix the tray. When the screw block moves downward, the pushing rod pushes the limiting post out of the through hole, at which point the connecting block can move upward to release the limiting part from fixing the tray. Thus, the limiting part can fix and release the tray by moving up and down with the screw block, enabling quick fixing and releasing of the tray and improving work efficiency.

[0020] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1 As shown, an automatic packaging equipment for automotive stamping parts includes an equipment frame 10; a base plate 11 is installed on the equipment frame 10, a drive mechanism 2 for driving the winding film roll to move up and down is provided on the upper right side of the base plate 11, and a rotating mechanism 3 for driving the stamping parts to rotate is provided on the left side of the drive mechanism 2.

[0033] like Figure 1 and Figure 2As shown, the driving mechanism 2 includes a fixed plate 20, which is mounted on the base plate 11. A sliding groove is provided on the left side of the fixed plate 20, and a lead screw 21 is rotatably mounted in the sliding groove. A screw block 22 is threadedly connected to the lead screw 21, and the screw block 22 is slidably mounted in the sliding groove. A stepper motor 23 for driving the lead screw 21 to rotate is mounted on the upper end of the fixed plate 20. A linkage part 24 is provided on the base plate 11, and a fixing part 25 for fixing the winding film roll is provided on the left side of the screw block 22.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the rotating mechanism 3 includes a rotating tube 30, which is rotatably mounted on the base plate 11. A turntable 31 is mounted on the upper end of the rotating tube 30, and a limiting part 34 is provided on the turntable 31. The linkage part 24 cooperates with the screw block 22 to drive the limiting part 34 to straighten and fix the pallet. A pressing part 35 is provided on the base plate 11 to limit the stamping part. The lower end of the rotating tube 30 and the lower end of the lead screw 21 both rotatably pass through the base plate 11 and are connected by a belt pulley mechanism.

[0035] In practice, the operator manually places the stretch film roll onto the fixing part 25, which then secures the roll. An external forklift moves the pallet and the stamped parts stacked on it onto the turntable 31. The stepper motor 23 then drives the lead screw 21 to rotate, causing the screw block 22 to move upwards a certain distance. This, through the linkage 24, drives the limiting part 34 to align and fix the pallet. The stepper motor 23 then continues to move the screw block 22 upwards via the lead screw 21, which in turn drives the rotating tube 3 through a pulley mechanism. The rotating tube 30 rotates, and the rotating tube 30 drives the fixed pallet and the stamped parts on the pallet to rotate through the turntable 31, so as to wrap the stretch film around the stamped parts and the pallet to realize the packaging process of the stamped parts. After the stamped parts are packaged, the stretch film is cut manually. Then the stepper motor 23 drives the lead screw 21 to rotate in the opposite direction. The lead screw 21 drives the screw block 22 to move down and reset. The limit part 34 is released from fixing the pallet through the linkage part 24. Then the external forklift removes the pallet and the stamped parts packaged on the pallet from the turntable 31 for centralized processing.

[0036] like Figure 2 and Figure 3As shown, the fixing part 25 includes a support plate 250. The support plate 250 is installed on the left end of the screw block 22. A first support plate 251 is installed on the lower part of the left end of the support plate 250. A second support plate 252 is slidably installed on the upper end of the support plate 250 through a guide rod. A compression spring 253 is installed between the lower end of the second support plate 252 and the support plate 250. A stop plate 254 is rotatably installed on the opposite surfaces of the first support plate 251 and the second support plate 252. A positioning post 255 is installed on the opposite surfaces of the two stop plates 254. A positioning element 7 is provided between the second support plate 252 and the screw block 22.

[0037] like Figure 2 and Figure 3 As shown, the positioning component 7 includes a rectangular plate. The rectangular plate is installed on the upper surface of the second support plate 252. A T-shaped column 70 is slidably installed on the rectangular plate. A tension spring 71 is installed between the vertical section of the T-shaped column 70 and the rectangular plate. A limiting hole is opened on the screw block 22 to cooperate with the T-shaped column 70 to limit the movement of the second support plate 252.

[0038] In practice, the T-shaped post 70 is manually pulled to the left, causing it to disengage from the limiting hole and simultaneously stretching the tension spring 71. Meanwhile, the second support plate 252 moves upward under the action of the compression spring 253, making the distance between the two positioning posts 255 greater than the height of the wrapping film roll. The wrapping film roll is then placed on the lower abutment plate 254, and the second support plate 252 is manually pressed down, causing the upper positioning post 255 to insert into the wrapping tube on the wrapping film. At the same time, the upper abutment plate 254 presses against the wrapping tube. At this point, the T-shaped post 70 moves to the position of the limiting hole, and under the action of the tension spring 71, it is inserted into the limiting hole to ensure that the wrapping tube rotates stably between the first support plate 251 and the second support plate 252.

[0039] like Figure 1 and Figure 2 As shown, the limiting part 34 includes a slot. The upper end of the turntable 31 has two slots symmetrically opened on the left and right. A slider is slidably installed in the slot. A connecting plate 340 is installed on the upper end of the slider. Two clamping plates 341 that are symmetrically arranged on the left and right sides of the two connecting plates 340 are slidably installed on the opposite sides. The clamping plates 341 have an L-shaped structure. The upper end of the turntable 31 is provided with a guide component that corresponds one-to-one with the clamping plates 341. The rotating tube 30 is provided with an actuator 4 for cooperating with the linkage part 24 to drive the two connecting plates 340 to move towards each other.

[0040] like Figure 2 As shown, the guide assembly includes a guide groove 342. The guide assembly consists of two guide grooves 342 that correspond to the transverse and longitudinal sections of the corresponding L-shaped plates, respectively. The clamping plate 341 is slidably connected to the corresponding guide groove 342 through guide posts.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, the pressing part 35 includes several bases 350 evenly distributed around the turntable 31. The lower end of the base 350 is connected to the upper end of the base plate 11 via an electric slider. The base 350 has an L-shaped structure. A support frame 351 is slidably installed on the horizontal section of the base 350. The support frame 351 has an F-shaped structure. A pressing rod 352 is rotatably installed on the two horizontal sections of the same support frame 351. A guide rod 353 that slides through the corresponding base 350 is installed at the end of the support frame 351 away from the turntable 31. A pressing spring 354 is provided between the support frame 351 and the corresponding base 350.

[0042] In actual operation, after the external forklift places the pallet and the stamped parts on the pallet onto the turntable 31, the stepper motor 23 drives the screw block 22 to move upward through the lead screw 21. The screw block 22 drives the actuator 4 through the linkage part 24. The actuator 4 then drives the two connecting plates 340 to move closer to each other. The connecting plates 340 drive the clamping plate 341 to move. The clamping plate 341 moves obliquely through the guide groove 342 until the clamping plate 341 presses against the pallet to restrict the pallet's forward, backward and left and right movement.

[0043] The end of the stretch film is then wrapped around the rear of the adjacent and front-positioned pressure bar 352 and fixed to the tray and stamping part. Then, the electric slider pushes the corresponding base 350 to move radially along the turntable 31 closer to the stamping part until the pressure bar 352 presses against the stamping part to limit its position. However, at this time, the pressure spring 354 is not in a fully contracted state, that is, it still has a certain amount of contraction to accommodate the increase in the thickness of the stretch film to be wrapped later. Then, the turntable 31 rotates synchronously through the pulley mechanism, causing the stamping part and the tray to rotate and pull out the stretch film for wrapping. During the wrapping process, the pressure bar 352 always limits the stamping part under the reaction force of the compressed pressure spring 354, thereby maintaining the stability of the stamping part. At the same time, the pressure bar 352 also always presses the stretch film against the stamping part to improve the adhesion between the stretch film and the stamping part, thereby improving the packaging quality of the stamping part.

[0044] like Figure 1 , Figure 5 and Figure 7 As shown, the linkage 24 includes a bearing seat. The lower end of the base plate 11 is equipped with a bearing seat. A drive rod 240 is rotatably mounted on both the front and rear ends of the bearing seat. A disc 241 is slidably mounted inside the rotating tube 30. A shaft 242 is rotatably mounted on the lower end of the disc 241. A rectangular block 243 is mounted on the lower end of the shaft 242 after passing through the rotating tube 30. A first waist groove is opened at both the left and right ends of the drive rod 240. A first roller shaft is slidably mounted on both the front and rear ends of the rectangular block 243, passing through the corresponding first waist groove. A push-pull member 5 for pushing and pulling the drive rod 240 to rotate is provided on the fixed plate 20.

[0045] like Figure 2 , Figure 7 and Figure 8 As shown, the actuator 4 includes a connecting plate 40. The upper end of the disc 241 is equipped with the connecting plate 40. The rotating tube 30 has two rectangular holes symmetrically opened on the left and right sides above the base plate 11. The two ends of the connecting plate 40 slide through the corresponding rectangular holes. The lower end of the turntable 31 is provided with a waist-shaped groove that corresponds to the slot. The lower end of the slider is equipped with a shaft column. After the shaft column slides through the corresponding waist-shaped groove, a sliding plate 41 is installed. A connecting rod 42 is hinged between the sliding plate 41 and the connecting plate 40.

[0046] like Figure 1 , Figure 2 and Figure 5 As shown, the push-pull component 5 includes a through groove. The right end of the fixed plate 20 has two through grooves that communicate with the slide groove. A lifting rod 50 is rotatably installed in the through groove via a torsion spring rod. The lifting rod 50 has an L-shaped structure, and one end of the lifting rod 50 abuts against the screw block 22. The other end of the lifting rod 50 has a second waist groove 51. A connecting block 52 located between the two lifting rods 50 is slidably installed on the bottom plate 11. The lower end of the connecting block 52 penetrates the bottom plate 11. Square plates located above the bottom plate 11 are installed at both the front and rear ends of the connecting block 52. A compression spring 53 is installed between the square plate and the bottom plate 11. A second roller shaft that slides through the corresponding second waist groove 51 is installed at both the front and rear ends of the upper part of the connecting block 52. A roller shaft that slides through the corresponding first waist groove is installed at both the front and rear ends of the lower part of the connecting block 52. A locking component 6 for fixing the connecting block 52 is provided on the fixed plate 20.

[0047] In operation, the stepper motor 23 drives the screw block 22 to move upward via the lead screw 21. The screw block 22 then pushes the connecting block 52 downward via the push-pull component 5. The connecting block 52 then pushes the right end of the drive rod 240 to rotate downward, causing the left end of the drive rod 240 to rotate upward and push the rectangular block 243 upward. The rectangular block 243 then pushes the connecting plate 40 upward via the disc 241 and the shaft 242. The connecting plate 40 then pushes the corresponding connecting plate 340 towards the pallet via the connecting rod 42 and the sliding plate 41 to fix the pallet via the limiting part 34. After the stamped parts are packaged, the stepper motor 23 drives the screw block 22 to move downward and reset via the lead screw 21, and drives the connecting plate 40 downward via the push-pull component 5 and the linkage part 24. The connecting plate 40 then pulls the clamping plate 341 away from the end face of the pallet via the connecting rod 42, the sliding plate 41 and the connecting plate 340. At this time, the packaged stamped parts and the pallet can be removed.

[0048] like Figure 2 , Figure 5 and Figure 6As shown, the locking component 6 includes a through hole. The connecting block 52 has two through holes symmetrically opened at the front and back. The fixing plate 20 is provided with a limiting post 60 corresponding to each of the through holes. The left end of the limiting post 60 slides through the fixing plate 20 into the slide groove. The limiting post 60 is provided with a protruding ring located in the slide groove. A return spring 61 is installed between the protruding ring on the limiting post 60 and the inner wall of the slide groove. An unlocking component that cooperates with the screw block 22 to push and pull the limiting post 60 to the left is provided in the slide groove.

[0049] like Figure 2 , Figure 4 and Figure 5 As shown, the unlocking component includes a push rod 62. Each of the two limiting posts 60 is hinged to a push rod 62 on its opposite side. The front and rear ends of the fixing plate 20 are provided with a third waist groove 63 at the position corresponding to the push rod 62. A third roller 64 is installed on the upper end of the push rod 62, which slides through the third waist groove 63.

[0050] In actual operation, as the screw block 22 moves upward, it abuts against the lifting rod 50, causing the lifting rod 50 to rotate clockwise. This rotation pushes the connecting block 52 downward, which in turn drives the limiting part 34 to fix the tray via the linkage part 24. As the connecting block 52 is pushed downward by the lifting rod 50, the through hole on the connecting block 52 moves to align with the limiting post 60. At this time, the limiting post 60 is pushed into the corresponding through hole by the return spring 61 to restrict the movement of the connecting block 52, thus keeping the limiting part 34 fixed to the tray. Then, the screw 21 continues to rotate, causing the fixing part 25 to move upward to... After the stamped parts are packaged, the stepper motor 23 drives the lead screw 21 to reverse, causing the screw block 22 to move downward. The screw block 22 will then come into contact with the push rod 62 and push the push rod 62 downward through the cooperation of the third roller shaft 64 and the third waist groove 63. The downward movement of the push rod 62 will pull the limiting post 60 to move to the left, causing the limiting post 60 to disengage from the limiting hole. The connecting block 52 will move upward and reset under the action of the compression spring 53. The upward movement of the connecting block 52 will release the limiting part 34 from fixing the pallet through the linkage part 24. At this time, the packaged stamped parts and the corresponding pallets are removed, and the above operation is repeated to continue the packaging process of the stamped parts.
