Description

Technical Field

[0001] The invention relates to a packaging line for electronic components to be assembled on site. Background Art

[0002] In electronics-related industries, such as the aerospace sector, a large number of power supply components, controllers, and other electronic components are required, which need to be assembled on-site. Existing solutions generally use boxes for packaging. The characteristic of the box is that the box is set up for easy storage. However, in actual use, it has the following problems: the boxes are close together with no gaps, which is not conducive to later movement. The accessories are placed in the box with no space, which makes it inconvenient to take them out. In practice, although electrical components generally use rectangular motherboards, due to their three-dimensional structure, space is still wasted, which is not much different from boxes with rounded corners. The space can be filled by adding some spare parts and documents. How to achieve full automation has become a technical problem that needs to be solved urgently. Existing assembly methods generally use assembly lines or rotating disks to realize the assembly and cover of accessory electronic components. Although the lines appear to be neatly distributed, they occupy a large area of ​​factory buildings in the current land-scarce environment, resulting in a waste of fixed assets.

[0048] The automatic loading process for aerospace electrical parts of this embodiment, wherein at least a portion of the outer wall of the box is a body of revolution; the process comprises the following steps:

[0049] S1, first, place the empty box at the input end of the accessory loading section; then, a conveyor belt with a pusher pushes the box forward, so that the empty box changes from a horizontal state to a vertical state and is transported to the guide input station 11; secondly, when the box reaches the guide input station 11, the cone head stop rod 13 is inserted into the gap between adjacent boxes to block the subsequent box output;

[0050] S2, with the help of the rotating working disk 7, the box is rotated in the plastic bag placing station 15, the accessories loading station 16, the sealing station 17, the labeling station 18 and the output station 19.

[0051] Among them, the following steps are performed in S2:

[0052] S2.1, at the guide input station 11, first, the C-shaped side frame 20 enters the gap of the bottom support seat 23 with the help of the C-shaped side opening 21 to push the box onto the bottom support seat 23; then, the bottom bracket 22 swings so that the side of the box is attached to the C-shaped side frame 20 for side positioning.

[0053] Among them, after S2.1, S 2.2 is executed, and the plastic bag is placed in the work station 15. First, the packaging bag feeding channel 24 sends the plastic bag, and the plastic bag is opened through the packaging bag back side suction nozzle 25 and the packaging bag same side suction nozzle 26; then, the packaging suction nozzle 32 blows air to the plastic bag; secondly, the packaging lifting rod 27 pushes down and enters the plastic bag opening; thirdly, the packaging sliding sleeve 29 moves downward, and the packaging umbrella-shaped opening hinge rod 28 is opened through the packaging linkage rod 30, so that the outer wall of the plastic bag contacts the inner wall of the box.

[0054] After S2.2, S2.3 is executed. At the accessory loading station 16, the bottom of the box is first lifted off the bottom bracket 22 by the bottom weighing unit 34. Then, the robot arm of the accessory feeding unit 33 places the accessory into a plastic bag, which is then inspected by the output inspection camera 12.

[0055] In S2.4, at the sealing station 17, first, the closing robot empties the plastic bag and closes it; then, the heat sealer closes the plastic bag;

[0056] In S2.5, at the labeling station 18, a labeling machine applies labels to the plastic bags;

[0058] The present invention is aimed at the falling packaging of existing electrical parts and accessories, and has good versatility. The work station connection is achieved by rotating the working disk 7, and the rotation guide direction of the box is achieved by the curved first side portion 8 and the curved second side portion 9. The box is fed into the guiding input station 11 through the guiding hollow portion 10 and the gap (added or removed as needed), and the output detection camera 12 is used for detection. The cone head shift lever 13 utilizes the characteristics of the rotating body to separate the boxes and block subsequent boxes. The output side lever 14 realizes the box output, and the corresponding process is completed in the plastic bag placing station 15, the accessories loading station 16, the sealing station 17, the labeling station 18, and the output station 19. The C-shaped side frame 20 has a C-shaped side opening 21 and a C-shaped side wall, which is convenient for the upper and lower boxes and the box handover. The bottom bracket 22 swings to facilitate the box to be thrown out from the opening under the action of the rotational inertia force due to sudden parking during the rotation process.

[0060] An inlet drive gear shaft 42 is provided at the inlet 39 of the channel, and the inlet drive gear shaft 42 is transmission-connected to an inlet reciprocating rack portion 43. An inlet drive flexible line 44 is provided at the end of the inlet reciprocating rack portion 43, and an inlet drive baffle 45 is provided at the end of the inlet drive flexible line 44. A hollow inlet process through hole 46 is provided at the bottom of the conical spiral transmission channel 36, and the cross section of the conical spiral transmission channel 36 is two L-shaped symmetrical structures.

[0061] An inlet process channel 47 is provided on the inlet drive baffle 45.

[0062] An inlet push front guide shaft 48 is provided at the end of the inlet drive flexible line 44, and an inlet guide taper head 51 is provided at the end of the inlet push front guide shaft 48. An inlet rear top plate 49 and an inlet front baffle 50 are provided on the inlet push front guide shaft 48, which are located on both sides of the inlet drive baffle 45.

[0063] The inlet push front guide shaft 48 is rotatably arranged in the inlet process channel 47.

[0064] An internal process auxiliary spiral brush roller 38 is rotatably arranged in the central hollow portion.

[0065] An auxiliary conveyor belt is provided at the hollow channel.

[0066] A channel deceleration baffle 41 is provided at the channel lower outlet 37 .

[0067] The inlet drive flexible line 44 is a steel wire rope or a soft shaft or is connected through several universal couplings.

[0068] The spiral conveying loading process of this embodiment includes the following steps: S3, conveying the box through the tapered spiral conveying channel 36 with a small upper part and a large lower part to complete the corresponding capping process on the tapered spiral conveying channel 36; specifically includes the following steps;

[0069] S3.1. First, the upper inlet 39 of the conical spiral conveyor channel 36 receives the pre-loaded box loaded with accessories from the loading conveyor 35. Then, the inlet drive gear shaft 42 engages the inlet reciprocating rack 43 and advances. Next, the inlet drive flexible wire 44 advances along the inlet process through-hole 46, driving the inlet rear top plate 49 to push the inlet drive baffle 45 forward in the conical spiral conveyor channel 36, allowing the box to move forward. Finally, the inlet front baffle 50 drives the inlet drive baffle 45 back to its initial position, ready for subsequent boxes to be dropped.

[0070] S3.2, first, the boxes are capped on the conical spiral conveying channel 36; then, the capped boxes are inspected; secondly, unqualified boxes are output through the channel side output channel 40, and qualified boxes are output through the channel lower outlet 37; thirdly, under the action of the channel lower outlet 37, the boxes are decelerated and blocked by the channel deceleration baffle 41.

[0071] During the conveying process of the conical spiral conveying channel 36, the inner process assists the spiral brush roller 38 to rotate to push the box forward flexibly.

[0072] The present invention realizes unloading through the loading conveyor part 35 (which can be a conventional push rod, conveyor belt or manipulator, etc.), and the conical spiral conveying channel 36, thereby gradually increasing the pitch, so that the boxes are automatically separated. The design is ingenious. During this period, an auxiliary speed-increasing conveyor belt or manipulator or an internal process auxiliary spiral brush roller 38 can be added to avoid jamming and achieve better separation. The lower outlet 37 of the channel is connected with the next process. This is one of the differences between the present invention and the traditional assembly line. It makes full use of the high three-dimensional space to match the corresponding auxiliary equipment. Waste discharge or corresponding output is achieved through the channel side output channel 40, and the channel deceleration baffle 41 achieves buffering. As the second improvement of the present invention, the inlet 39 on the channel is optimized, the inlet drive gear shaft 42, and the inlet reciprocating rack part 43 realize linear reciprocating drive, realize auxiliary pushing one by one, and increase the initial power. Compared with the traditional push rod, the imported drive flexible line 44 is well suited for spiral structures and has good flexibility. It realizes spiral guidance through the imported process channel 47 and uses its own elastic force to solve the problem of changing direction, so that the imported drive baffle 45 can be pushed forward in a spiral manner. The imported process through hole 46 realizes the rotation connection of the imported push front guide shaft 48, and spiral pushing and reverse pullback are realized through the imported rear top plate 49 and the imported front baffle 50. The imported guide tapered head 51 has good guiding properties, so that the flexible line can change direction better. Since there is no restriction on the rotational freedom of the flexible line at the end, the stress generated during its flexible rotation can be fully released, which is not available in the existing technology.

[0073] The present invention realizes transformation of the assembly line, thereby solving the occupation of land resources and realizing smooth advancement of the spiral circling push.

After the buckle cover guide conical surface 79 descends and enters the buckle cover process gap 78, it is in elastic pressure and friction contact with the outer wall of the descending elastic radial telescopic arm 66 of the buckle cover. The buckle cover swing arm 69 is provided with a buckle cover hinge portion 70, which serves as a fulcrum for the buckle cover swing arm 69 to swing.

[0079] A first guide groove 71 for the buckle cover is provided in the middle of the lifting buckle cover swing arm 69, and a buckle cover linkage pin 74 provided with a buckle cover front stop driving arm 72 moves in the first guide groove 71;

[0081] The buckle cover assembly process of this embodiment includes step S5, in which the buckle cover is buckled onto the box located in the conical spiral conveying channel at the buckle cover loading station; specifically, the following steps are included:

[0082] S5.1, first, the buckle cover is sent to the buckle cover loading terminal 62 through the buckle cover feeding conveyor 61; then, the buckle cover changing output part 64 drives the buckle cover lifting rack 65 to descend; secondly, after the buckle cover guide cone 79 descends and passes through the buckle cover process gap 78, the outer wall of the buckle cover elastic radial telescopic arm 66 elastically contacts the corresponding side wall of the buckle cover process gap 78 with the elastic radial telescopic arm 66 on the buckle cover with dynamic friction, so that the buckle cover swing arm 69 swings; then, the buckle cover linkage pin 74 slides in the buckle cover first guide groove 71, so that the buckle cover front stop driving arm 72 descends along the buckle cover guide column 73; then, the buckle cover front stop driving arm 72 drives the buckle cover process bent arm 75 to swing downward and insert into the conical spiral conveying channel to block the box at the buckle cover loading station, and at the same time, the buckle cover magnet of the buckle cover swing bent arm 69 attracts the corresponding buckle cover magnetic seat 77 and is blocked from continuing to descend;

[0083] S5.2, first, the elastic radial telescopic arm 66 on the buckle cover dynamically rubs against the corresponding side wall of the buckle cover process gap 78 and continues to move downward; then, the buckle cover negative pressure adsorption lower head 68 pushes the buckle cover located on the buckle cover feeding terminal 62 downward, pushes the buckle cover open and downwardly engages the baffle 63, so that the buckle cover is buckled onto the box pre-loaded with electrical accessories on the conical spiral transmission channel.

[0084] After the buckle is engaged, after S5.2, S5.3 is executed. First, the buckle cover lifting rack 65 is driven to move in the opposite direction, and the elastic radial telescopic arm 66 on the buckle cover rubs against the corresponding side wall of the buckle cover process gap 78 and moves upward in the opposite direction, so that the buckle cover magnet of the buckle cover swing arm 69 is separated from the buckle cover magnetic seat 77, and the buckle cover downward engaging baffle 63 automatically elastically resets and closes upward; then, the buckle cover lifting rack 65 continues to move upward, so that the elastic radial telescopic arm 66 on the buckle cover is separated from the corresponding side wall of the buckle cover process gap 78; finally, the buckle cover lower support plate 67 lifts the tail of the buckle cover swing arm 69 and engages with the corresponding buckle cover magnetic seat 77, so that the buckle cover front stop arm 76 rises, and the buckled box continues to move forward and leaves the buckle cover loading station.

[0085] The present invention addresses the problem of snapping the cover on the spiral channel, and realizes automatic loading through the snapping cover feeding conveyor 61. The snapping cover feeding terminal 62 completes the installation of the snapping cover on the box. The downward-engaging baffle 63 of the snapping cover is reset by a spring and opened by downward force. The snapping cover changing output part 64 can realize linkage control with other workstations, thereby replacing the sensor. The design is ingenious and reduces costs. The snapping cover lifting rack 65 realizes linear drive. The elastic radial telescopic arm 66 on the snapping cover of the present invention can realize the opening of the external top support through the retaining spring, thereby realizing elastic pressure contact with the snapping cover process gap 78, and can realize downward movement of friction while maintaining the position limit, thereby solving the problem of action difference and ensuring that the box is pre-positioned when the snapping cover falls.
