However, in actual use, it has the following problems: the boxes are close together and there is no gap, which is not conducive to later movement. The accessories are in the box without gaps, which is inconvenient to take. In practice, although electrical parts generally use rectangular motherboards, due to their three-dimensional structure, space is still wasted, which is not much different from boxes with arc corners.

[0060] 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 located on both sides of the inlet drive baffle 45 are provided on the inlet push front guide shaft 48;

[0061] The inlet push front guide shaft 48 is rotatably arranged in the inlet process channel 47.

[0062] An internal process-assisting spiral brush roller 38 is rotatably arranged in the central hollow portion.

[0063] An auxiliary conveyor belt is arranged at the hollow channel.

[0064] A channel deceleration baffle 41 is provided at the channel lower outlet 37 .

[0065] The inlet drive flexible line 44 is a steel wire rope or a flexible shaft or is connected through several universal couplings.

[0066] The spiral conveying feeding process of this embodiment includes the following steps: S3, conveying the box through the tapered spiral conveying channel 36 with a small top and a large bottom, so as to complete the corresponding capping process on the tapered spiral conveying channel 36; specifically includes the following steps;

[0067] S3.1. First, the upper inlet 39 of the conical spiral conveying channel 36 receives the box pre-loaded with fittings sent by the feeding conveying part 35. Then, the inlet driving gear shaft 42 meshes with the inlet reciprocating rack part 43 and advances. Secondly, the inlet driving flexible line 44 advances along the inlet process through-hole 46, driving the rear top plate 49 of the inlet to push the inlet driving baffle 45 to advance in the conical spiral conveying channel 36, so that the box advances. Thirdly, the front baffle 50 of the inlet drives the inlet driving baffle 45 to pull back to the initial station for the subsequent box to fall.

[0068] S3.2. First, cover the box on the conical spiral conveying channel 36. Then, inspect the box after capping. Secondly, for the unqualified boxes, output them through the side output channel 40 of the channel, and for the qualified boxes, output them through the lower outlet 37 of the channel. Thirdly, under the action of the lower outlet 37 of the channel, decelerate and block through the channel deceleration baffle 41.

[0069] During the conveying process of the conical spiral conveying channel 36, the internal process auxiliary spiral brush roller 38 rotates to gently push the box forward.

[0070] The present invention realizes blanking through the feeding conveying part 35 (which can be a conventional push rod, conveyor belt or manipulator, etc.) and the conical spiral conveying channel 36, so as to gradually increase the pitch, so that the boxes are automatically separated. The design is ingenious. During this period, an auxiliary accelerating conveyor belt, manipulator or internal process auxiliary spiral brush roller 38 can be added to avoid jamming and achieve better spacing. The lower outlet 37 of the channel realizes connection with the next process, which is one of the differences between the present invention and the traditional assembly line.

Compared with the traditional push rod, the inlet driving flexible line 44 can be well applied to the spiral structure, has good flexibility, realizes spiral guiding through the inlet process channel 47, and uses its own elasticity to solve the problem of direction change, so that the inlet driving baffle 45 advances spirally to push. The inlet process through-hole 46 realizes the rotational connection of the front guiding rotating shaft 48 of the inlet push. Through the rear top plate 49 of the inlet and the front baffle 50 of the inlet, spiral pushing and reverse pulling back are realized. The inlet guiding taper head 51 has good guiding performance to make the flexible line 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 prior art.

[0079] The buckle cover assembly process of this embodiment includes step S5, at the buckle cover loading station, buckling the buckle cover on the box located in the conical spiral conveying channel; specifically includes the following steps:

[0080] S5.1, first, the buckle cover is sent to the buckle cover feeding 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 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 elastic pressure; again, the buckle cover corresponding side wall of the buckle cover process gap 78 is in dynamic friction contact with the buckle cover elastic radial telescopic arm 66, 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 feeding 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;

[0081] S5.2, first, the elastic radial telescopic arm 66 on the buckle cover rubs against the side wall corresponding to 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 plate 63, so that the buckle cover is buckled onto the box preloaded with electrical accessories on the conical spiral transmission channel.

[0082] After the snap-fitting, after S5.2, S5.3 is executed, first, the snap-cover lifting rack 65 is driven to move in the reverse direction, and the elastic radial telescopic arm 66 on the snap-cover dynamically rubs against the corresponding side wall of the snap-cover process gap 78 and moves upward in the reverse direction, so that the snap-cover magnet of the snap-cover swing arm 69 is separated from the snap-cover magnetic seat 77, and the snap-cover downward engaging baffle 63 automatically elastically resets upward and closes; then, the snap-cover lifting rack 65 continues to move upward, so that the elastic radial telescopic arm 66 on the snap-cover is separated from the corresponding side wall of the snap-cover process gap 78; finally, the snap-cover lower support plate 67 lifts up the tail of the snap-cover swing arm 69 and engages with the corresponding snap-cover magnetic seat 77, so that the snap-cover front stop arm 76 rises, and the snap-fitted box continues to move forward and leaves the snap-cover loading station.

[0083] In view of the problem of screwing on the cover for the spiral channel, the present invention realizes automatic feeding through the cover feeding and conveying part 61, the cover feeding terminal 62 completes the installation of the cover onto the box, the cover downward alignment baffle 63 is reset by a spring and opens under downward force, and through the cover direction-changing output part 64, linkage control with other workstations can be achieved, thus replacing the sensor.
