Description

Technical Field

[0001] This invention belongs to the field of engine manufacturing, and more specifically, relates to an engine packaging box opening and closing device and method. Background Technology

[0002] Currently, on a certain small engine automated assembly line, during the engine boxing process, a warehouse robot places the packaging box on a roller conveyor. The roller conveyor then twists the box to a manual operation area where the lid is opened. The automated boxing station completes the engine boxing, and the roller conveyor twists the box back to the manual operation area where the engine is placed and the lid is closed. Finally, the roller conveyor twists the box back to the robot's pickup station for warehousing. The disadvantages are: due to the large size of the box lids, two people are required to operate the manual opening / closing process. Furthermore, the current production line has a compact structure and lacks a temporary storage area for the lids, which would obstruct personnel movement. During the opening / closing process, errors in coordination between the two operators can easily result in the product being dropped or bumped. The temporary storage area for the lids also poses a significant tripping hazard, creating a high safety risk. Manual operation is inefficient, and since engines are hazardous materials, requiring two operators increases overall assembly costs and the upper limit of personnel safety requirements in the workshop.

Detailed Implementation

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1-10 As shown, an engine packaging box opening and closing device includes a roller conveyor 1, and an opening and closing mechanism frame 2 and an unlocking and positioning component 3 are provided on the frame of the track line 1.

[0041] like Figures 4-5 As shown, the unlocking and positioning component 3 includes a positioning frame 301, on which a positioning cylinder 302 is provided. The telescopic end of the positioning cylinder 302 is provided with a positioning block 303 for positioning the packaging box 4. In this embodiment, the end of the positioning block 303 is an arc-shaped surface that matches the corner of the packaging box 4, so that the positioning cylinder 302 extends and the positioning block 303 positions the two sides of the packaging box 4.

[0042] Preferably, the positioning frame 301 is equipped with an unlocking cylinder 304 for the latch of the packaging box 4. The unlocking cylinder 304 extends and pushes to unlock the latch of the packaging box 4, facilitating the separation of the top cover from the box body when opening the lid.

[0043] The lid picking mechanism 5 and the lid temporary storage mechanism 6 are mounted on the lid opening and closing mechanism frame 2, such as... Figures 8-10 As shown, the box cover temporary storage mechanism 6 includes a temporary storage base plate 601, which is fixedly installed on the opening and closing mechanism frame 2, and the box cover 7 is stacked on the temporary storage base plate 601.

[0044] Preferably, a lid positioning fixture 602 is provided at the upper corner of the temporary storage base plate 601. The lid positioning fixture 602 positions the stacked lids 7 and is located at the four corners of the stacked lids 7. A sliding seat 603 is provided at the lower end of the lid positioning fixture 602. A sliding through hole is provided on the temporary storage base plate 601 for the sliding seat 603 to slide. A slide rail 604 and a positioning fixture pull rod 605 are provided on the lower side of the temporary storage base plate 601. The sliding seat 603 is connected to the slide seat of the slide rail 604. One end of the positioning fixture pull rod 605 is hinged to the sliding seat 603, and the other end is hinged to the rotating seat 606 provided on the temporary storage base plate 601. The tail end of the lid positioning cylinder 607 is hinged to the mounting base 608, and the telescopic end of the lid positioning cylinder 607 is hinged to the connecting seat 609 on the rotating seat 606.

[0045] The lid positioning cylinder 607 drives the rotating seat 606 to rotate. Under the pull of the positioning fixture pull rod 605, the lid positioning fixture 602 moves along the slide rail 604, thereby causing the lid positioning fixture 602 to move away from the stacked lids 7, releasing the limit on the stacked lids 7, making it easier to put down or take out the lids 7. The lid positioning cylinder 607 retracts, driving the rotating seat 606 to rotate in the opposite direction, causing the lid positioning fixture 602 to move towards the opposite direction, clamping the stacked lids 7, which can prevent the lids 7 from shifting horizontally, thus preventing the lid picking mechanism 5 from closing the lids due to positional deviation. It can accurately position the lids 7, ensuring the accuracy of lid closing alignment.

[0046] Preferably, the temporary storage base plate 601 is provided with a sensor mounting bracket 610. The sensor mounting bracket 610 is provided with a lid layer detection sensor 611 along the height of each lid 7. By setting the lid layer detection sensor 611, the position of the empty layer can be detected, so that the lid picking mechanism 5 can accurately move the suction cup assembly 8 to the target layer to pick up the lid 7.

[0047] like Figures 2-3 As shown, the lid picking mechanism 5 includes a displacement cylinder 501 and a guide rail 502 mounted on the lid opening and closing mechanism frame 2. The displacement cylinder 501 is a rodless cylinder. The direction of the guide rail 502 is the same as the moving direction of the displacement cylinder 501. The bottom of the displacement frame 503 is connected to the slider of the displacement cylinder 501. The bottom of the displacement frame 503 is provided with a guide block 504 that cooperates with the guide rail 502. The displacement frame 503 is provided with a lifting mechanism 505. The picking column 506 is mounted on the moving part of the lifting mechanism 505. The lower end of the picking column 506 is provided with a suction cup assembly 8.

[0048] In this embodiment, the lifting mechanism 505 is a screw jack, and the nut of the screw jack is connected to the picking column 506. A lifting cylinder can also be used instead of a screw jack.

[0049] like Figures 6-7 As shown, the suction cup assembly 8 includes a suction cup holder 801, and a vacuum suction cup 802 is mounted on the suction cup holder 801. In this embodiment, the vacuum suction cup 802 is a sponge vacuum suction cup, and two sets are selected to improve the picking stability.

[0050] A buffer spring 803 is provided between the vacuum suction cup 802 and the suction cup fixing frame 801. The buffer spring 803 is fitted onto the guide rod 804. The suction cup fixing frame 801 is provided with a through hole for the guide rod 804 to pass through.

[0051] By setting a buffer spring 803, adaptive operation is achieved when the height dimension of the packaging box 4 is unstable.

[0052] Preferred, such as Figure 7 As shown, the bottom of the suction cup holder 801 is provided with a box cover detection assembly, which includes a detection rod 9. The suction cup holder 801 is provided with a through hole for the detection rod 9 to pass through. The detection rod 9 can move up and down along the through hole. Limiting nuts 10 are provided at both the upper and lower ends of the detection rod 9. A spring 11 is mounted on the detection rod 9. The spring 11 is located between the lower limiting nut 10 and the suction cup holder 801. A limit switch 12 is provided above the detection rod 9. Specifically, the limit switch 12 is located on one side directly above the detection rod 9.

[0053] When in use, after the vacuum suction cup 802 adsorbs the box cover 7, the box cover 7 will push the detection rod 9 upward and move it to the side of the limit switch 12. The limit switch 12 can determine that the adsorption of the box cover 7 has been completed by detecting the signal, thus preventing the box cover 7 from not being adsorbed.

[0054] The suction cup mounting bracket 801 has a locking cylinder 13 at its bottom corresponding to the latch of the box cover 7. The locking cylinder 13 extends vertically. When the locking cylinder 13 is activated, it extends downwards, pressing down and locking the box latch, thus achieving automatic locking between the box cover 7 and the box body.

The box cover positioning cylinder 607 pushes the rotating seat 606 to rotate. Under the pull of the positioning fixture pull rod 605, the box cover positioning fixture 602 moves along the slide rail 604. The lifting mechanism 505 is started, which drives the suction cup assembly 8 to move down. The vacuum suction cup 802 is closed, and the box cover 7 is placed on the box cover temporary storage mechanism 6.
