DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0029] Example 1

[0030] Reference Figures 3 to 5 As shown, a box body cover device of the present invention comprises: a conveying component 1 for conveying a box body 9 to be covered; an assembling component 3, comprising a flipping mechanism and a shaping mechanism, wherein the flipping mechanism comprises a top plate 32 capable of moving toward the edge of the conveying component 1, the top plate 32 capable of folding the end plate on the box body 9 to be covered, the shaping mechanism comprises a baffle 39 and a movable pressing plate 36, the pressing plate 36 capable of bending the tongue on the box body 9 to be covered that extends from the baffle 39 away from the conveying component 1; a first guide component 4, comprising a guide seat 41, a first guide rod 44, a first guide plate 42 and a second guide rod 43. Plate 43, the first guide plate 42 and the second guide plate 43 are both connected to the guide seat 41, and a guide space is formed between the first guide rod 44 and the guide seat 41. The first guide plate 42 can keep the end plate on the box body 9 to be covered in a folded state during the movement, and the second guide plate 43 can keep the tongue on the box body 9 to be covered in a bent state during the movement; the cover-closing component 5 is located at the end of the first guide component 4 away from the assembly component 3, and the cover-closing component 5 includes a first push rod 52 and a second push rod 54 that can move respectively toward the direction close to the conveying component 1.

[0031] The box body cover-locking device of this embodiment drives the box body 9 to be covered to move by the conveying component 1, and the box body 9 to be covered moves to the assembly position of the assembly component 3, and then the top plate 32 folds the second end plate 94 on the box body 9 to be covered, and the first end plate 91 of the box body 9 to be covered is located on the pressure plate 36, and the first latch 92 connected to the end plate is extended from the baffle 39, and the pressure plate 36 bends the first latch 92. After the assembly is completed, the conveying component 1 drives the box body 9 to be covered to continue moving, and the hanging plate 93 of the box body 9 to be covered is located on the first guide rod 44, and the second end plate 94 is abutted against the first guide plate 42, and the first end plate 91 and the latch are abutted against the second end plate 94. Finally, the box body 9 to be covered moves to the cover-locking position of the cover-locking component 5, and the push rod squeezes the two ends of the first latch 92 respectively, so that the first latch 92 extends into the bayonet 95 on the second end plate 94 to complete the cover-locking action. By assembling the component 3, the second end plate 94 can be folded and the first tongue 92 can be bent at the same time. The setting of the first guide rod 44 can prevent the angle between the suspension plate 93 and the first end plate 91 from being too small to affect the subsequent cover-fastening action. The first guide plate 42 can keep the second end plate 94 in a folded state during the movement, and can also keep the first rocker leaf 96 in a folded state during the movement. The second guide plate 43 can keep the first tongue 92 in a bent state during the movement. The push rod can enable the first tongue 92 to be inserted into the bayonet 95 to complete the cover-fastening action. The overall cover-fastening action does not require manual operation, thereby improving the cover-fastening efficiency of the box body.

[0032] Reference Figure 1 and Figure 2 As shown, the box body 9 to be covered includes openings at both ends, the edge of one opening is provided with a first end plate 91 and a second end plate 94 arranged opposite to each other, and the edge of the other opening is provided with a third end plate 97. A hanging plate 93 is provided on the first end plate 91, a first latch 92 is provided on the edge of the first end plate 91, and a bayonet 95 is provided on the second end plate 94 to cooperate with the first latch 92. The width of the bayonet 95 is smaller than the width of the first latch 92. A card slot 921 is provided at both ends of the connection position between the first latch 92 and the end plate, so that after the first latch 92 is inserted into the bayonet 95, the card slot 921 can be engaged with the edge of the bayonet 95. A second latch 98 is provided on the edge of the second end plate 94. The box body 9 to be covered has the first end plate 91 and the second end plate 94. The opening edges at one end are also provided with a first rocking leaf 96 arranged opposite to each other, and the opening edge at one end of the box body 9 to be covered has the third end plate 97. It is also provided with a second rocking leaf 99 arranged opposite to each other.

[0033] Reference Figure 3As shown, the conveying assembly 1 is used to convey the box body 9 to be covered. The conveying assembly 1 includes a movable plate 11 and a limit seat 2. The limit seat 2 is connected to the movable plate 11, and the movable plate 11 can rotate. The movable plate 11 is annular as a whole. The movable plate 11 is driven to rotate by a motor. The box body 9 to be covered is engaged with the limit seat 2. The rotation of the movable plate 11 drives the box body 9 to be covered to move. The annular structure of the movable plate 11 and the rotating conveying method enable the assembly component 3, the first guide component 4 and the cover-covering component 5 to be arranged along the edge of the movable plate 11. Compared with the existing linear conveying method, the annular structure of the movable plate 11 and the rotating conveying method make the box body cover-covering device occupy a smaller area.

[0034] Reference Figure 6 As shown, a plurality of limit seats 2 are equidistantly arranged along the edge of the movable plate 11. The limit seats 2 include a connecting plate and a receiving member 21. The receiving member 21 includes a receiving space for receiving the box body 9 to be covered. Openings are provided at both ends of the receiving member 21, and the openings are arranged along the radius of the movable plate 11. The opening position of the box body 9 to be covered corresponds to the opening of the receiving member 21. The size of the receiving space corresponds to the main body of the box body 9 to be covered. The first end plate 91 and the second end plate 94 of the box body 9 to be covered can extend from the opening of the receiving member 21 away from the rotation axis of the movable plate 11, and the third end plate 97 of the box body 9 to be covered can extend from the other opening of the receiving member 21. When the box body 9 to be covered is located in the receiving space, the first end plate 91 and the third end plate 97 are located at the top of the box body 9 to be covered, and the second end plate 94 is located at the bottom of the box body 9 to be covered. The bottom of the accommodating member 21 is connected to the connecting plate. A barrier rod 22 is hingedly connected to both sides of the connecting plate and the corresponding side walls of the accommodating member 21. The barrier rod 22 is generally U-shaped, and the end of the barrier rod 22 is rotatably connected to a roller 23. The roller 23 abuts against the external boss, allowing the barrier rod 22 to rotate into the accommodating space, thereby allowing the top of the barrier rod 22 to extend into the accommodating space and abut against the top of the main body of the box body 9 to be covered in the accommodating space. At this time, the box body 9 to be covered is engaged with the limit seat 2 and fixed in position. Preferably, a stopper 24 is also connected to the connecting plate, which can abut against the barrier rod 22 to limit the rotation angle of the barrier rod 22.

[0035] Reference Figure 5As shown, the assembly component 3, the first guide component 4, and the cover component 5 are sequentially arranged along the conveying path of the conveying component 1. The assembly component 3 includes a flipping mechanism and a shaping mechanism. The flipping mechanism includes a top plate 32 that can move toward the edge of the conveying component 1. Specifically, the flipping component also includes a first driving member 31. The top plate 32 is connected to the output end of the first driving member 31, and the first driving member 31 is fixed to the outside via a first mounting bracket 33. The assembly component 3 is located below the movable plate 11. The first driving member 31 can drive the top plate 32 to rise and move toward the edge of the movable plate 11. The moving path of the top plate 32 is perpendicular to the movable plate 11. When the top plate 32 is in an extended state, there is a gap between the top plate 32 and the edge of the movable plate 11. The top of the top plate 32 and the side of the top plate 32 facing the feeding direction of the conveying component 1 are both arc-shaped. After the second end plate 94 of the box body 9 to be covered is abutted against the top plate 32, it will be guided by the arc-shaped side and will tilt up. Then the first driving member 31 drives the top plate 32 to drop quickly and then rise again. Since the second end plate 94 loses the support of the top plate 32, it will remain in the tilted state for a certain period of time. When the second end plate 94 starts to rotate downward, the top plate 32 again abuts against the second end plate 94 and drives the second end plate 94 to fold upward, so that the second end plate 94 is located close to the opening position of the box body 9 to be covered.

[0036] The shaping mechanism includes a baffle 39 and a movable pressure plate 36. The pressure plate 36 is capable of bending the tab on the cover box body 9 that extends away from the conveyor assembly 1 from the baffle 39. Specifically, the shaping mechanism also includes a second drive member 35 and a third drive member 37. The second drive member 35, the third drive member 37, and the baffle 39 are all fixed to the exterior via a second mounting bracket 34. The baffle 39 is generally L-shaped. The position where the baffle 39 abuts the first end plate 91 extends along a tangent to the travel path of the movable plate 11. After the first end plate 91 abuts the baffle 39, the edge of the baffle 39 away from the conveyor assembly 1 corresponds to the connection position between the first end plate 91 and the first tab 92. The pressure plate 36 is connected to the output end of the second drive member 35, and the movement path of the pressure plate 36 is perpendicular to the plane of the movable plate 11. The output end of the third drive member 37 is connected to the first push plate 38, and the movement path of the first push plate 38 is parallel to the plane of the movable plate 11. When the first push plate 38 is in the extended state, it is located below the baffle 39 and there is a gap between it and the baffle 39. The pressing plate 36 can extend between the first push plate 38 and the baffle 39, and when the pressing plate 36 is in the extended state, there is a gap between them. After the first end plate 91 of the cover box body 9 is positioned on the baffle 39, the second driving member 35 drives the pressing plate 36 to press down and bend the first latch 92, so that the first latch 92 is perpendicular to the first end plate 91. The pressing plate 36 then retracts, and the third driving member 37 drives the first push plate 38 to bend the first latch 92 again, so that the first latch 92 bends toward the conveying assembly 1. At this time, the first latch 92 forms an acute angle with the first end plate 91.

[0037] The first guide assembly 4 comprises a guide base 41, a first guide rod 44, a first guide plate 42 and a second guide plate 43, the first guide plate 42 and the second guide plate 43 are connected with the guide base 41, and the first guide rod 44 is connected with the external support. The first guide rod 44, the first guide plate 42, the second guide plate 43 and the guide base 41 all extend along the conveying path of the movable plate 11 in the conveying assembly 1 near the edge of the conveying assembly 1, that is, the first guide rod 44, the first guide plate 42, the second guide plate 43 and the guide base 41 all have an arc shape. The first guide plate 42 is located on the guide base 41 near the edge of the conveying assembly 1, the second guide plate 43 corresponds to the shaping position of the shaping mechanism near one end of the shaping mechanism, the first guide rod 44 corresponds to the position of the baffle 39 near one end of the baffle 39, and the end of the first guide rod 44 near the baffle 39 is higher than the end of the first guide rod 44 near the baffle 39. After the bending of the first clamping tongue 92 is completed, in the movement of the to-be-latched cover box body 9 driven by the movable plate 11, the first end plate 91 and the first clamping tongue 92 can enter the guide space formed between the first guide rod 44 and the guide base 41 through the gap between the first guide rod 44 and the baffle 39, the connection position of the first end plate 91 and the first clamping tongue 92 abuts against the second guide plate 43, thereby preventing the first clamping tongue 92 from rebounding and enabling the first clamping tongue 92 to continue to maintain the bent state in the movement; meanwhile, the suspension plate 93 abuts against the position of the first guide rod 44 away from the guide base 41, thereby preventing the angle between the suspension plate 93 and the first end plate 91 from being too small, avoiding that the small included angle between the suspension plate 93 and the first end plate 91 affects the subsequent latching action, and preferably, the minimum included angle between the suspension plate 93 and the first end plate 91 is greater than 30°. The end of the first guide plate 42 corresponds to the folding position of the second end plate 94, and after the folding of the second end plate 94 is completed by the folding mechanism, in the movement of the to-be-latched cover box body 9 driven by the movable plate 11, the second end plate 94 abuts against the first guide plate 42, thereby enabling the second end plate 94 to maintain the folded state in the movement.

[0038] The first guide plate 42 is provided with a third guide plate 45 extending away from the conveying assembly 1 near one end of the assembly assembly 3, and the plane where the first guide plate 42 is located forms an obtuse angle with the plane where the third guide plate 45 is located, that is, the third guide plate 45 is arranged in an inclined manner, which can guide the movement of the second end plate 94 and position the second end plate 94, so that the second end plate 94 is closer to the opening of the to-be-latched cover box body 9. The second guide plate 43 is connected with a fourth guide plate 46 near one side of the guide base 41, the fourth guide plate 46 extends towards the conveying assembly 1, and the plane where the second guide plate 43 is located forms an obtuse angle with the plane where the fourth guide plate 46 is located, thereby enabling the first clamping tongue 92 to abut against the fourth guide plate 46 in the movement of the first end plate 91, thereby further preventing the first clamping tongue 92 from rebounding and enabling the first clamping tongue 92 to maintain the bent state.

[0039] The buckle cover assembly 5 is located at the end of the first guide assembly 4 away from the assembling assembly 3, the buckle cover assembly 5 comprises a push rod capable of extruding the clamping tongue, specifically, the buckle cover assembly 5 comprises a fourth driving member 51 and a fifth driving member 53, the push rod comprises a first push rod 52 and a second push rod 54, the output end of the fourth driving member 51 is connected with the first push rod 52, the output end of the fifth driving member 53 is connected with the second push rod 54, the fourth driving member 51 and the fifth driving member 53 are fixed outside through the third mounting frame. The distance between the first push rod 52 and the second push rod 54 gradually increases in the direction approaching the conveying assembly 1, that is, the distance between the first push rod 52 and the second push rod 54 approaching the conveying assembly 1 forms a V-shaped space. The distance between the first push rod 52 and the second push rod 54 corresponds to the width of the first clamping tongue 92, the fourth driving member 51 drives the first push rod 52 to abut against one end of the first clamping tongue 92 and extrude the first clamping tongue 92, so that one end of the first clamping tongue 92 first extends into the clamping hole 95, then the fifth driving member 53 drives the second push rod 54 to abut against one end of the second clamping tongue 98, so that the first clamping tongue 92 extends into the clamping hole 95 completely, and the second end plate 94 is fixed in position. The distance between the first push rod 52 and the second push rod 54 gradually increases in the direction approaching the conveying assembly 1, so that one end of the first clamping tongue 92 can enter the clamping hole 95 in an oblique and inclined manner, so that the first clamping tongue 92 can enter the clamping hole 95 with a smaller width than the width of the first clamping tongue 92.

[0040] Referring to Figure 7 As shown in the drawings, the middle position of the movable plate 11 is slidingly connected with the mounting plate 12, and the mounting plate 12 is fixed outside. The mounting plate 12 is also provided with a second limiting assembly 6, the second limiting assembly 6 comprises a sixth driving member 61, the sixth driving member 61 is connected with the mounting plate 12, and the output end of the sixth driving member 61 is connected with a second push plate 62, the second push plate 62 can move in the direction approaching the movable plate 11, and the second push plate 62 can push the third end plate 97 in the direction approaching the opening of the to-be-buckled cover box body 9, so as to make the third end plate 97 fold.
