Description

Technical Field

[0001] The invention relates to the field of hardware accessories assembly and manufacturing, specifically to the field of plate support production, and in particular to automatic assembly equipment for layer plate supports. Background Art

[0002] Shelf supports are common hardware accessories in life and are mostly used in panel furniture, especially wardrobes, cabinets, shoe cabinets, bookcases and other cabinet-type layered furniture. One end is fixed to the side wall of the furniture or wall, and the other end is parallel to the ground. It is used to place wooden boards or glass shelves. There are many types of shelf supports, which can be divided into wooden shelf supports, glass shelf supports, metal shelf supports, etc. according to their uses.

[0003] Attachment Figure 1 What is shown is a common shelf support in life, including an L-shaped body a, with screw holes on the vertical plate of the body a. When in use, the expansion sleeve c is inserted into the connecting hole of the wall panel, and then the vertical plate of the body a is fitted with the wall panel and the screw b is passed through the screw hole to form a threaded connection with the expansion sleeve c. Then, the screw b is screwed with a tool such as a screwdriver to expand the expansion sleeve c, forming a firm connection with the connecting hole, thereby achieving fixation between the shelf support and the wall panel. Since the shelf support includes three parts: the body a, the screw b and the expansion sleeve c, the quantity of the three parts needs to be counted when it is sold and shipped, and it is easy to miss parts. Therefore, when producing the shelf support, you can do the following: Figure 1 In the picture on the right, the three parts are assembled first. This way, it is unlikely that one part will be delivered in excess and another part will be delivered in short supply.

[0004] In the prior art, such as Figure 2 and Figure 3 As shown, during the assembly of the three parts of the shelf support, the end of the screw b is generally pushed through the screw hole by a cylinder and then inserted into the expansion sleeve c. The expansion sleeve c is generally made of materials such as rubber or silicone. Although this method can realize the assembly of the shelf support, it is easy for the screw b to damage the expansion sleeve c.

[0005] Based on the above, the present invention proposes an automatic assembly device for a shelf support, which can drive the end thread of the screw b to screw into the expansion sleeve c, thereby realizing the automatic assembly of the shelf support with high efficiency and without damaging the various parts of the shelf support.

DETAILED DESCRIPTION

[0040] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0041] In the attached drawings of this scheme, def refers to the vibrating plate, which is respectively connected to the first conveying pipe 101, the second conveying pipe 102 and the third conveying pipe 103, and conveys the three parts constituting the layer support thereto in an orderly manner. This is achievable with existing technology and will not be described in detail.

[0042] Reference Figure 4-Figure 12 , a layer tray automatic assembly device includes an assembly frame and an assembly mechanism 100 arranged on the assembly frame.

[0043] The assembly mechanism 100 includes an assembly seat 107, a screw feed assembly located above the assembly seat 107, an expansion sleeve feed assembly located below the assembly seat 107, and a body feed assembly located on the side of the assembly seat 107. The body, screw and expansion sleeve are three parts that make up the shelf support and will not be described in detail.

[0044] During use, the body is pulled into the assembly seat 107 through the body feeding assembly, and the body is pushed into the assembly position through the assembly seat 107. Then, through the cooperation of the screw feeding assembly and the expansion sleeve feeding assembly, the screw is moved down through the screw hole set on the body, and the expansion sleeve is moved up. At the same time, the screw rotates and the thread is screwed into the expansion sleeve, thereby completing the assembly of the shelf support. Finally, the assembled shelf support is pushed away by the assembly seat 107, and then reset to the next assembly. This process is repeated to realize the automated assembly line of the shelf support.

[0045] Assembly seat 107: Refer to Figure 7 and Figure 8The assembly seat 107 includes an upper plate seat 1071 and a lower plate seat 1072 arranged on the assembly frame, and a movable seat 1074 and a horizontal column 1073 located therebetween.

[0046] An assembly hole is provided on the end surface of the upper plate seat 1071 , and an output notch 1076 is provided on the end surface of the lower plate seat 1072 . The output notch 1076 is located below the movable seat 1074 and one side of the output notch 1076 is configured to be an arc shape coaxial with the assembly hole.

[0047] The sliding directions of the movable seat 1074 and the horizontal column 1073 are consistent and initially, the two are located on both sides of the assembly hole. A spring 1077 is arranged between the movable seat 1074 and the assembly frame. The elastic force of the spring 1077 is used to drive the movable seat 1074 to move closer to the assembly hole. A linear module 115 is provided on the assembly frame for driving the horizontal column 1073 to move.

[0048] An input notch 1078 is provided on the assembly rack. Initially, the area between the horizontal column 1073 and the assembly hole is connected to the input notch 1078 .

[0049] Furthermore, there is a guide sleeve 1075 below the assembly hole, and the guide sleeve 1075 is connected to the movable seat 1074. The purpose of providing the guide sleeve 1075 is to play a limiting and guiding role for the screw during the subsequent assembly process.

[0050] Body feed assembly: refer to Figure 4 The main body feeding assembly includes a first conveying pipe 101 arranged at the mouth of the input notch 1078. The first conveying pipe 101 can pull the main body close to the input notch 1078, and finally the main body can enter the area between the cross column 1073 and the assembly hole through the input notch 1078. The first conveying pipe 101 and the second conveying pipe 102 mentioned later can adopt the existing vibration plate technology and will not be elaborated.

[0051] Screw feed assembly: refer to Figure 5 、 Figure 9 and Figure 10 The screw feeding assembly includes an upper rotating body 105 which is mounted on the upper surface of the upper plate seat 1071 and is in the shape of a cylinder with a vertical axis. The upper rotating body 105 is power-connected to a first motor 110 provided on the assembly frame, and the upper rotating body 105 can be driven to rotate by the first motor 110.

[0052] An upper storage hole is provided through the end surface of the upper rotating body 105. A plurality of upper storage holes are arranged in an array along the circumferential direction of the upper rotating body 105. During the rotation of the upper rotating body 105, the upper storage holes can be coaxially connected with the assembly hole.

[0053] A third conveying pipe 103 is installed on the assembly frame and is located above the upper rotating body 105. When one of the upper storage holes is coaxial with the assembly hole, the third conveying pipe 103 is coaxial with any one of the remaining upper storage holes. When the screw is inserted into the third conveying pipe 103, the screw can fall into the upper storage hole under the action of gravity. Afterwards, as the upper rotating body 105 rotates, the screw can fall into the assembly hole.

[0054] The screw feeding assembly also includes a connecting bracket 112 and a linear module 111 that drives the connecting bracket 112 to move in the vertical direction. A motor frame is provided on the connecting bracket 112 through a pressure sensor, and a second motor 113 is installed on the motor frame. The output end of the second motor 113 is coaxially connected to a rotating shaft 116. The rotating shaft 116 is coaxial with the assembly hole and is located above the upper rotating body 105.

[0055] The bottom of the rotating shaft 116 is provided with a screwdriver head 117, and the outer sleeve of the rotating shaft 116 is provided with a ring magnet 118. Furthermore, the bottom of the rotating shaft 116 is provided with an external step, and the upper end of the ring magnet 118 is provided with an internal step. The internal step is sleeved on the outside of the rotating shaft 116 and supported by the external step. Initially, the screwdriver head 117 is hidden in the ring magnet 118, and the outside of the rotating shaft 116 is provided with a limiting ring located above the ring magnet 118. A spring 2 119 is provided between the limiting ring and the ring magnet 118. Therefore, the ring magnet 118 can move in the vertical direction and form a rotational fit with the rotating shaft 116. The screw can be magnetically attracted by the ring magnet 118. Therefore, when the screw is rotated to the top of the assembly hole, it will be magnetically attracted by the ring magnet 118 at the first time. Afterwards, the connecting bracket 112 is driven downward by the linear module 2 111, and the downward movement of the connecting bracket 112 can carry electricity The frame, the second motor 113, the rotating shaft 116, the annular magnet 118 and the screw move downward together, so that the screw passes through the assembly hole and the guide sleeve 1075. When the bottom of the screw contacts the expansion sleeve, the downward movement of the screw is hindered and temporarily does not move. The annular magnet 118 also does not move, and the screwdriver head 117 and the rotating shaft 116 continue to move downward. The second spring 119 is compressed. When the screwdriver head 117 contacts the screw, the downward movement of the rotating shaft 116 is also hindered. This situation can be detected by the pressure sensor, and then a signal is sent to rotate the second motor 113, and the rotating shaft 116 and the screwdriver head 117 rotate together until the screwdriver head 117 is aligned with the cross slot on the screw. The obstruction disappears, and the rotating shaft 116 can continue to move downward, so that the screwdriver head 117 is inserted into the cross slot of the screw. The rotation of the second motor 113 can rotate with the screw, and cooperate with the downward movement to screw the screw into the expansion sleeve.

[0056] Expansion sleeve feed assembly: refer to Figure 11 and Figure 12The expansion sleeve feeding assembly includes a lower rotating body 106 coaxial with the upper rotating body 105. The lower rotating body 106 is powered by a first motor 110 provided on the assembly frame, and the lower rotating body 106 can be driven to rotate by the first motor 110.

[0057] The upper end surface of the lower rotating body 106 is provided with a lower storage groove. There are several lower storage grooves arranged in an array along the circumferential direction of the lower rotating body 106, and the number is consistent with the upper storage holes. During the rotation of the lower rotating body 106, the lower storage groove can be coaxial with the assembly hole.

[0058] A supporting seat 1061 is slidably installed in the lower storage tank. The supporting seat 1061 is a cylindrical shape with an open upper end and a closed lower end. A convex seat is provided at its lower closed end. The convex seat and the lower storage tank form a sliding guide fit. A spring three 1062 is provided between the convex seat and the fixing ring provided at the notch of the lower storage tank. When the expansion sleeve is located in the supporting seat 1061, the upper end of the expansion sleeve is higher than the upper end of the supporting seat 1061.

[0059] A second conveying pipe 102 is installed on the assembly frame. A blanking hole is opened at the bottom of the output end of the second conveying pipe 102. When a lower storage tank is coaxial with the assembly hole, the blanking hole is coaxially located above any one of the remaining lower storage tanks.

[0060] A through hole is coaxially provided through the bottom of the lower storage tank, and a top column 120 coaxial with the assembly hole is provided below the lower rotating body 106. A linear module three 114 is provided on the assembly frame for driving the top column 120 to move in the vertical direction; when the top column 120 is driven to move upward by the linear module three 114, the supporting seat 1061 can be lifted upward by the top column 120, thereby pushing the expansion sleeve upward, so that the upper end of the expansion sleeve contacts the lower surface of the lower plate seat 1072.

[0061] Working principle of the present invention:

[0062] Step 1: The main body is pulled by the first conveying pipe 101, passes through the input notch 1078, and enters the area between the crossbar 1073 and the assembly hole. Under the action of gravity, the screws in the third conveying pipe 103 can fall into the upper storage hole. The expansion sleeve is pulled by the second conveying pipe 102, falls through the drop hole into the support seat 1061 of the lower storage tank.

[0063] Step 2: The linear module 115 pulls the horizontal column 1073 to move closer to the movable seat 1074. The horizontal column 1073 moves with the main body until the main body contacts the movable seat 1074. At this time, the screw hole on the main body is coaxial with the assembly hole.

[0064] Step 3: The linear module 114 drives the push column 120 upward, and the push column 120 pushes the support seat 1061 upward, thereby pushing the expansion sleeve upward, so that the upper end of the expansion sleeve contacts the lower surface of the lower plate seat 1072;

[0065] At the same time, the screw located just above the assembly hole will be magnetically attracted by the annular magnet 118. Afterwards, the connecting bracket 112 is driven downward by the second linear module 111. The downward movement of the connecting bracket 112 can move the motor frame, the second motor 113, the rotating shaft 116, the annular magnet 118 and the screw downward together, so that the screw passes through the assembly hole and the guide sleeve 1075. When the bottom of the screw contacts the expansion sleeve, the downward movement of the screw is hindered and temporarily does not move. The annular magnet 118 also does not move, while the screwdriver head 117 and the rotating shaft 116 continue to move downward, and the spring 117 and the second spring 117 are in a state of rotation. 19 is compressed. When the screwdriver head 117 contacts the screw, the downward movement of the rotating shaft 116 is also hindered. This situation can be detected by the pressure sensor, and then a signal is sent to rotate the second motor 113, and the rotating shaft 116 and the screwdriver head 117 rotate together until the screwdriver head 117 is aligned with the cross slot on the screw. The obstruction disappears and the rotating shaft 116 can continue to move downward, so that the screwdriver head 117 is inserted into the cross slot of the screw. The rotation of the second motor 113 can rotate with the screw, and cooperate with the downward movement to screw the screw into the expansion sleeve;

[0066] It should be noted that, since the expansion sleeve is in contact with the lower surface of the lower plate seat 1072, the expansion sleeve is blocked and cannot rotate, thereby enabling the screw to be screwed into the expansion sleeve.

[0067] It should be noted that the magnetic attraction between the ring magnet 118 and the screw is relatively weak, as long as it can attract the screw. Therefore, when the bottom of the screw contacts the expansion sleeve, the ring magnet 118 and the screw will not rotate when the screwdriver head 117 rotates, so that the screwdriver head 117 and the cross slot are aligned.

[0068] Step 3: Since the screw and the expansion sleeve form a threaded connection, when the connecting bracket 112 is driven upward by the second linear module 111, the screw and the expansion sleeve will not move upward until the connecting bracket 112 is completely reset. At the same time, the top column 120 is driven downward and reset by the third linear module 114.

[0069] Step 4: The linear module 115 pulls the horizontal column 1073 to continue moving, thereby pushing the assembled layer support to the output gap 1076. At this time, since the layer support is clamped by the horizontal column 1073 and the movable seat 1074, refer to Figure 5A sliding hole can be provided through the end surface of the upper plate seat 1071 above the output notch 1076. A sliding sleeve is connected to the upper opening of the sliding hole. A vertical column 109 is sleeved in the sliding sleeve. A linear module 108 is provided on the assembly frame for driving the vertical column 109 to move in the vertical direction. The linear module 108 drives the vertical column 109 downward, thereby pushing the shelf support down and dropping it onto the output pipe 104, and being guided out by the output pipe 104.

[0070] Step 5: Use the linear module 108 to drive the vertical column 109 to move upward and reset;

[0071] The linear module 4 115 pulls the horizontal column 1073 back to reset, and the spring 1 1077 releases the elastic force to reset the movable seat 1074;

[0072] At the same time, the upper rotating body 105 and the lower rotating body 106 are driven to rotate by the first motor 110, and the rotation angle is equal to the central angle between two adjacent upper storage holes;

[0073] Repeat steps 1 to 5 to achieve automated assembly of the shelf support.

[0074] From the above description we can see that:

[0075] This solution can realize the automated assembly of the layer support. Specifically, on the one hand, this solution realizes the automatic alignment of the screwdriver head and the cross slot on the screw, so that the screw can be screwed into the expansion sleeve during assembly, which has a higher degree of automation and the various components of the layer support will not be damaged due to assembly. On the other hand, during assembly, this solution drives the expansion sleeve to move upward to conflict with the lower plate seat, and drives the screw downward at the same time. This method can increase the relative movement speed between the screw and the expansion sleeve, thereby reducing the time spent on screwing the screw into the expansion sleeve. The time saved by assembling several layer supports is relatively objective, so the assembly efficiency can be improved. In addition, the upward movement of the expansion sleeve and the conflict with the lower plate seat can also cooperate with the screw, so that the screw can be screwed into the expansion sleeve smoothly and smoothly.

Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
