Description

Technical Field

[0001] This utility model relates to the field of pin assembly, specifically to an automatic feeding assembly mechanism for toolboxes. Background Technology

[0002] The flip-top toolbox opens and closes via hinges, with a latch serving as the core component of the hinge. Currently, installing the latch into the pre-drilled hole in the toolbox is done manually. Specifically, a person manually places the latch into a fixture beforehand, then places the toolbox into the fixture to align with the latch, and finally uses a cylinder to push the latch into the toolbox hole to complete the assembly. This assembly method requires repeated manual placement of the latch and control of the cylinder each time, resulting in low production efficiency and significantly impacting the production cycle. Furthermore, manual placement and assembly of the latch with the toolbox can easily lead to misalignment between the latch and the hole, causing severe bending, deformation, or even breakage of the latch, rendering it unusable.

Detailed Implementation

[0073] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0074] Example:

[0075] like Figures 1 to 16 As shown, an automatic feeding and assembly mechanism for a toolbox 20 includes:

[0076] Feed rack 1;

[0077] The feeding roller has several strip-shaped material distribution grooves 211 evenly distributed around its axis on its cylindrical surface; the material distribution grooves 211 pass through both ends of the feeding roller; the feeding roller is rotatably mounted on the feeding frame 1 around its axis.

[0078] The feeding motor 3 is coaxially connected to the feeding roller and is mounted on the feeding roller to control the rotation of the feeding roller.

[0079] The material box has a funnel-shaped structure with an opening at the bottom that wraps around the upper parts of both ends of the feeding roller and the upper part of the feeding roller, and is used to accommodate the pin 10.

[0080] The receiving mechanism is located below the feeding roller, and its upper surface is provided with a receiving groove 541 parallel to the feeding roller's distributing groove 211;

[0081] The material guiding mechanism is located on the outer cylindrical surface of the feeding roller. Its upper end is connected to the surrounding box, and its lower end is located directly above the receiving groove 541. It controls the pin 10 located inside the feeding roller to fall into the receiving groove 541. The minimum distance between the inner side of the material guiding mechanism and the cylindrical surface of the feeding roller is less than the diameter of the pin 10.

[0082] The material pushing mechanism is located outside the material receiving mechanism. Its telescopic end pushes the pin 10 located in the material receiving groove 541 to slide along the material receiving groove 541.

[0083] Toolbox fixture 8 is set at one end of receiving groove 541. When toolbox 20 is placed into toolbox fixture 8, pin 10 in receiving groove 541 can be collinear with the insertion hole of toolbox 20.

[0084] The pin 10 is manually placed into the feeding box. The feeding motor 3 controls the rotation of the feeding roller, which has several feeding slots 211 with the same width as the pin 10. Each rotation causes one pin 10 to be inserted into one of these slots. As the pin 10 rotates to the bottom of the feeding roller, it falls naturally due to gravity. Below is a reciprocating mechanism that causes the pin 10 to fall into the receiving seat 54. The pushing mechanism then assembles the pin 10 with the toolbox 20. This embodiment can automatically feed the pins, achieving continuous and rapid feeding of the pins 10, greatly improving production efficiency and reducing manual operation time and labor intensity. Compared with the traditional method of manually placing the pins 10, the automatic feeding equipment can greatly shorten the cycle time and improve the enterprise's production capacity and market competitiveness. This embodiment, through its designed mechanical structure, ensures accurate positioning of the pins 10 during the feeding process, avoiding jamming or misalignment.

[0085] In this embodiment, the feeding roller includes:

[0086] The roller body 21 is cylindrical, and several strip-shaped material distribution grooves 211 are evenly distributed around its axis on its cylindrical surface; both ends of the roller body 21 are provided with concave grooves 212.

[0087] The head shaft 213 has its tail end set in the groove 212 at the head end of the roller body 21 and is coaxially fixed to the roller body 21. The head end is rotatably set on the feeding frame 1 through a bearing and coaxially connected to the distributing motor 3.

[0088] The tail shaft 214 has its tail end set in the groove 212 at the tail end of the roller body 21 and is coaxially fixed to the roller body 21. Its head end is rotatably set on the feed rack 1 through a bearing.

[0089] This design of the feed roller facilitates maintenance and replacement.

[0090] In this embodiment, the surrounding box includes:

[0091] Two first side columns 41 are arranged vertically side by side on one side of the feeding roller;

[0092] The first side plate 42 is inclined and its two ends are flush with the two ends of the feeding roller; its outer side plate surface is fixed to the upper end of the two first side columns 41, and the lower end of the first side plate 42 points to the cylindrical surface of the feeding roller, and the gap between it and the cylindrical surface of the feeding roller does not exceed the diameter of the pin 10.

[0093] Two second side columns 43 are arranged vertically side by side on one side of the feed roller;

[0094] The second side plate 44 is inclined and its two ends are flush with the two ends of the feeding roller; its outer side plate surface is fixedly connected to the upper end of the two second side columns 43, and the lower end of the second side plate 44 points to the cylindrical surface of the feeding roller, and the gap between it and the cylindrical surface of the feeding roller does not exceed the diameter of the pin 10; the upper end of the guiding mechanism is fixedly connected to the lower end of the second side plate 44.

[0095] The head side plate 45 is located on the outer side of the feeding roller head end, and the inner side plate surface is fixedly connected to the end faces of the corresponding first side plate 42 and second side plate 44; the lower end of the head side plate 45 covers the end face of the material distribution groove 211 at the upper part of the feeding roller head end.

[0096] Tail side plate 46 is disposed on the outer side of the tail end of the feeding roller, and the inner side plate surface is fixedly connected to the end face of the corresponding first side plate 42 and second side plate 44; the lower end of the tail side plate 46 covers the end face of the material distribution groove 211 at the tail end of the feeding roller.

[0097] The first side plate 42, the second side plate 44, the head side plate 45, and the tail side plate 46 form a funnel-shaped structure with an opening pointing towards the feed roller.

[0098] In this embodiment, the lower end of the first side plate 42 is lower than the lower end of the second side plate 44; the distance between the plane of the first side plate 42 and the axis of the feeding roller is greater than the distance between the plane of the second side plate 44 and the axis of the feeding roller.

[0099] By setting the first side plate 42 to be more inclined and the lower end lower, the pin 10 is more easily agitated when the feeding roller rotates from the first side plate 42 to the second side plate 44, thus falling into the distributing trough 211.

[0100] In this embodiment, the material guiding mechanism includes:

[0101] The guide plate 61 has a tile-shaped structure and is set on the outer cylindrical surface of the feeding roller. Its upper end is connected to the surrounding box, and its lower end is located directly below the axis of the feeding roller. The two ends of the guide mechanism are flush with the two ends of the feeding roller.

[0102] The support base 62 is disposed on the outer side of the guide plate 61, and its outer surface is in contact with the outer surface of the guide plate 61;

[0103] A support plate 63 is disposed below a support base 62 and is fixedly connected to the support base 62; both ends of the support plate 63 are fixedly connected to a receiving mechanism; when the pushing mechanism pushes the insertion holes of the pin 10 and toolbox 20 in the receiving groove 541 to move, the support plate 63 covers the upper part of the receiving groove 541.

[0104] The guide plate 61 ensures that the pin 10 moves smoothly to the bottom of the feed roller. The support base 62 prevents deformation of the guide plate 61, and the support plate 63 provides support and protects the pin 10 during insertion into the socket.

[0105] In this embodiment, the material guiding mechanism further includes:

[0106] The upper end of the feeding plate 64 is fixedly connected to the lower end of the guide plate 61, and the plate surface is perpendicular to the horizontal plane.

[0107] The guide blocks 65 are respectively set at the head and tail of the feeding roller and are fixedly connected to the feeding frame 1; the side of the guide block 65 facing the feed plate 64 is an inclined surface 651, which guides the pin 10 falling from the feeding roller to fall downward.

[0108] The design of the feed plate 64 and the guide block 65 ensures that the pins 10 falling from the feed roller will fall smoothly into the receiving groove 541.

[0109] In this embodiment, the receiving mechanism includes:

[0110] The receiving guide slide rail 51 has its axis perpendicular to the axis of the feeding roller;

[0111] The sliding seat 52 is mounted on the receiving guide slide rail 51;

[0112] The receiving cylinder 53 is located outside the receiving guide slide rail 51, and its telescopic end is connected to the sliding seat 52 to control the sliding displacement of the sliding seat 52 on the receiving guide slide rail 51.

[0113] The receiving seat 54 is set on the sliding seat 52, and the upper surface is provided with a receiving groove 541 parallel to the material distribution groove 211 on the feeding roller.

[0114] Because the gap between the receiving groove 541 and the feeding roller is small, the sliding seat 52 is set to a variable position in order to facilitate the pushing mechanism to push the pin 10 to rotate.

[0115] In this embodiment, the receiving mechanism further includes:

[0116] The head end seat 55 is set on the head end side of the receiving seat 54, and its upper surface is provided with a head end groove 551 with the same outline size as the receiving groove 541.

[0117] Tail end seat 56 is provided on the tail end side of receiving seat 54, and its upper surface is provided with a tail end groove 561 with the same outline size as receiving groove 541.

[0118] The receiving seat 54, under the control of the receiving cylinder 53, has a receiving groove 541 that is collinear with the head end groove 551, the tail end groove 561, and the insertion hole of the toolbox 20 located in the toolbox fixture 8.

[0119] Setting the head end seat 55 and the tail end seat 56 can better guide and limit the movement of the pin 10.

[0120] In this embodiment, the pushing mechanism includes:

[0121] The pusher cylinder 71 is positioned on the outside of the toolbox fixture 8, parallel to the axis of the feed roller.

[0122] The pusher guide 72 is arranged parallel to the axis of the feed roller and is located on the outside of the feed roller;

[0123] The pusher slider 73 is mounted on the pusher slide rail and is connected to the telescopic end of the pusher cylinder 71;

[0124] The pusher 74 is connected at one end to the pusher slider 73, and the other end is located in the receiving groove 541, directly facing the end face of the pin 10 in the receiving groove 541.

[0125] In this embodiment, the outer side of the material receiving mechanism facing the pusher slider 73 forms a guide rail structure 9 with the material receiving groove 541; the lower surface of the pusher 74 is provided with a guide groove 741 that matches the guide rail structure 9.

[0126] The guide rail structure 9 and the guide slide rail can form another guide limit, which, together with the pusher guide rail 72, forms a double slide rail limit structure to ensure the smooth operation of the pusher component 74. The pusher component 74 can complete the seamless double slide rail limit under the guidance of the head end seat 55 and the tail end seat 56.

[0127] The automatic feeding assembly mechanism of toolbox 20 in this embodiment works as follows: Figure 17 As shown, insert the pin 10 into the material box and place the toolbox 20 into the toolbox fixture 8. Start the material distribution motor 3 and rotate it at intervals according to a certain rotation angle, so that the pin 10 falls into the material distribution groove 211 in the feeding roller.

[0128] When the feeding roller rotates to a certain angle, that is, when the pin 10 inside the feeding roller is no longer restricted by the guide plate 61 and thus falls into the feeding roller, the distributing motor 3 is stopped. The pin 10 falls into the receiving groove 541 of the receiving seat 54 under the restriction of the feeding plate 64 and the guide block.

[0129] Control the receiving cylinder 53 to align the receiving seat 54 with the head end seat 55 and the tail end seat 56. Then control the pushing cylinder 71 to shorten, and the ejector pushes the pin 10 to slide into the insertion hole of the toolbox 20 until the pin 10 is fully inserted into the insertion hole.

[0130] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
