A smart sealing device for furniture brackets

Abstract

A smart sealing device for furniture supports includes a material distribution chute with screening grooves arranged sequentially on it. A guide chute is located at the lower end of the material distribution chute and is connected to one of the screening grooves. The bottom wall of the guide chute has impact holes with reciprocating impact pins inside. Anti-tilting cones are symmetrically arranged in the guide chute, with a separation groove in the middle of each cone. The separation groove is configured to match the impact holes. In this invention, the screening grooves on the material distribution chute can screen and seal from three dimensions, allowing seals in the desired direction to be screened out and proceed to the next process. The impacting pins then dislodge upward-opening seals, leaving downward-opening seals that meet the requirements. The anti-tilting cones on the guide chute ensure that the seals are transported perpendicular to the chute, preventing tipping during transport. This eliminates the need for AOI (Automated Optical Inspection) equipment.

Description

Technical Field

[0001] This invention belongs to the field of furniture packaging technology, specifically referring to an intelligent sealing device for furniture brackets. Background Technology

[0002] After the furniture frame is painted, the open ends need to be sealed. Sealing protects the cleanliness of the pipe, preventing contaminants from entering the frame tube, and also acts as a buffer, protecting the pipe ends. Commonly used seals have equidistantly arranged corrugated protrusions on their outer wall, and the end of the seal that embeds into the frame tube is designed as a hollow opening to reduce material usage. The corrugated design increases the contact area between the seal and the inner wall of the pipe, enhancing sealing with less material and absorbing deformation of the frame tube under pressure changes or temperature fluctuations, thus adapting to pipe deformation.

[0003] In actual assembly, controlling the direction of the seal becomes a significant technical challenge. Existing production processes mainly rely on automated optical inspection (AOI) equipment to ensure the correct installation orientation of the seal. While this approach is effective, it also introduces a significant operational burden. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an intelligent sealing device for furniture brackets, which at least partially solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes an intelligent sealing device for furniture brackets, including a material distribution chute for screening and sealing. The material distribution chute is provided with a plurality of screening grooves arranged in sequence. The size of each screening groove is configured to match the size of each cross section of the sealing component in three-dimensional space, so as to screen and guide the sealing component.

[0006] A guide trough is connected to the lower end of the material distribution chute. The guide trough is connected to one of the screening troughs of the material distribution chute. The bottom wall of the guide trough is provided with a striking hole, and a reciprocating sliding striking pin is provided in the striking hole.

[0007] Anti-tilting cone plates are symmetrically arranged in the guide chute, and a separation groove is provided in the middle of the anti-tilting cone plate, the separation groove being adapted to the position of the impact hole;

[0008] A pre-compression cylinder is located at the end of the anti-tilting cone plate. A secondary compression cylinder is also provided at the rear end of the pre-compression cylinder. The pre-compression cylinder is used to pre-compress the seal into the bracket, and the secondary compression cylinder compacts the pre-compressed seal a second time.

[0009] In some embodiments, the lower wall of the feed trough is provided with multiple sets of guide posts, and flanges are slidably provided on the guide posts. The striking needle is located on the side of the flange close to the feed trough.

[0010] In some embodiments, a cam is connected to the side end of the flange, a second motor is connected to the side end of the cam, and a first spring is connected between the flange and the side wall of the guide trough.

[0011] In some embodiments, the anti-tilting cone plate is slidably disposed on the walls of the guide trough on both sides, and multiple sets of screws are provided through the upper walls of both sides of the guide trough. The lower ends of the screws are disposed on the upper walls of the anti-tilting cone plate, and a second spring is connected between the lower wall of the anti-tilting cone plate and the bottom wall of the guide trough.

[0012] In some embodiments, the anti-tilt cone is provided with an open cone on the inner side near the end region, and the opening direction of the open cone is toward the pre-compression cylinder.

[0013] In some embodiments, the end of the guide trough is provided with a discharge notch, and the discharge notch is adapted to the position of the opening cone.

[0014] In some embodiments, the anti-tilt cone plate has an arc plate at its end, and the end of the arc plate is horizontally positioned.

[0015] In some embodiments, the intelligent sealing device for furniture brackets proposed in this invention further includes a hopper for holding the sealing material. The lower end of the hopper is provided with a first motor, and the output shaft of the first motor is provided with a material distribution wheel. The material distribution wheel is rotatably located at the outlet of the hopper and is used to control the amount of material discharged from the hopper each time.

[0016] In some embodiments, the hopper is also connected to a vibration device, which can drive the hopper, the material distribution chute and the guide chute to vibrate together.

[0017] In some embodiments, the intelligent sealing device for furniture brackets proposed in this invention further includes a conveyor belt for conveying the brackets.

[0018] The beneficial effects achieved by this invention are as follows:

[0019] The screening trough on the material distribution chute can screen the plugs from three dimensions, allowing plugs in the required direction to be screened out and enter the next process. Then, the impacting needles will knock out the plugs with upward openings, thus retaining the plugs with downward openings that meet the requirements. The anti-tilting cone plate on the guide chute can keep the plugs perpendicular to the guide chute during transportation, preventing them from tipping over during transportation. The above equipment can intelligently screen the plugs that meet the requirements to the port of the bracket, and then intelligently maintain the direction of the plugs so that they are embedded into the port of the bracket tube. It can achieve intelligent positioning and installation throughout the process without relying on AOI equipment. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] like Figure 1 and Figure 7 As shown in the figure, an intelligent sealing device for furniture brackets proposed in this embodiment of the invention includes a hopper 1, a conveyor belt 5, and a material distribution chute 3. The hopper 1 contains sealing materials, and a first motor 2 is provided at the lower end of the hopper 1. A material distribution wheel (not shown in the figure) is provided on the output shaft of the first motor 2. The material distribution wheel is rotatably located at the discharge port of the hopper 1 and is used to control the amount of material discharged from the hopper 1 each time. In some embodiments, the material distribution wheel releases only one sealing material at a time. The material distribution chute 3 is connected to the discharge port of the hopper 1 and is used to screen the sealing materials. Screening grooves 22 are arranged sequentially on the material distribution chute 3. The dimensions of 2 are adapted to the cross-sectional dimensions of the sealing in each three-dimensional plane. In some embodiments, the screening groove 22 is provided in three sets, corresponding to the three planes of the three-dimensional coordinate system. That is, the sealing needs to go through three layers of screening: screening in one direction according to the length and width, screening in one direction according to the length and height, and screening in one direction according to the width and height. Only the sealing groove 22 with the direction matching the screening groove 22 can enter the required screening groove 22 for subsequent sealing of the support. The conveyor belt 5 is located below the hopper 1. The conveyor belt 5 is used to transport the support M to be sealed, so that the support M to be sealed is arranged in sequence to the position of sealing and pressing.

[0034] like Figure 2 and Figure 4As shown, a guide trough 4 is connected to the lower end of the material distribution chute 3. Both the material distribution chute 3 and the guide trough 4 are inclined downwards to allow the seal to slide under gravity. The guide trough 4 is connected to one of the screening grooves 22 of the material distribution chute 3. The connection channel of the guide trough 4 is selected according to the requirements and the model and specifications of the seal. All three sets of screening grooves 22 can be connected to the guide trough 4. It is only necessary to ensure that the seal separating the screening groove 22 from the guide trough 4 meets the installation requirements. In some embodiments, the seal separating to the guide trough 4 still has two distribution directions, namely, one end embedded in the hollow opening of the bracket. With the hollow opening of the plug facing upwards or embedded in the bracket facing downwards, the bottom wall of the feed trough 4 is provided with a striking hole 18. A reciprocating striking needle 10 is provided in the striking hole 18. When the striking needle 10 reciprocates, if the hollow opening of the plug is downwards, the striking needle 10 will insert into the hollow opening. The striking needle 10 will not contact the plug and will not affect the normal movement of the plug. If the hollow opening of the plug is upwards, the striking needle 10 will quickly strike the end cap of the plug, causing the plug to fly away from the feed trough 4 under the action of external force, thereby completing the screening of the plug.

[0035] In some embodiments, a vibration device is also connected to the hopper 1. The vibration device can drive the hopper 1, the material distribution chute 3 and the guide chute 4 to vibrate together, so as to promote the movement of the blockage in each component and avoid the blockage phenomenon.

[0036] In some embodiments, such as Figures 4-6 As shown, to prevent the seals from tilting in the feed chute 4 and to ensure that all seals maintain a consistent direction, anti-tilting cone plates 14 are symmetrically provided on both sides of the feed chute 4. The inner side of the anti-tilting cone plate 14 is set as a cone, which can be embedded between adjacent corrugated protrusions N on the seal, such as... Figure 8 As shown, the sealing provides a certain supporting force to prevent the sealing from tipping over when it slides in the guide trough 4. The sealing in the same direction and the anti-tilting cone plate 14 are in the same position. The sealing in different directions and the anti-tilting cone plate 14 may be in different positions. That is, the sealing with the hollow opening facing upward and the corrugated protrusion N are at the same height. The sealing with the hollow opening facing downward and the corrugated protrusion N are at the same height. However, the height of the sealing with the hollow opening facing upward and the sealing with the hollow opening facing downward may be different, but it does not affect the conveying of the sealing. The anti-tilting cone plate 14 is provided with a separation groove 19 in the middle. The separation groove 19 is adapted to the position of the striking hole 18. When the striking needle 10 hits the sealing and separates the sealing from the guide trough 4, the separation groove 19 can provide a clearance space for the sealing to fly away and avoid obstructing the sealing.

[0037] In some embodiments, such as Figure 1As shown, the anti-tilting cone plate 14 is equipped with a pre-compression cylinder 6 at its end. When the plug falls from the guide chute 4, it will align with the port of the support M to be plugged, which is moved here by the conveyor belt 5. The pre-compression cylinder 6 applies pressure to the plug, pre-compressing the plug into the support, so that the plug and the support are initially fitted together. The rear end of the pre-compression cylinder 6 is also equipped with a secondary compression cylinder 7. When the secondary compression cylinder 7 extends and retracts, it will compress the pre-compressed plug a second time, so that the plug is completely embedded in the support.

[0038] In some embodiments, such as Figure 2 As shown, the lower wall of the guide trough 4 is provided with multiple sets of guide posts 8, and a flange 9 is slidably provided on the guide posts 8. The striking needle 10 is located on the side of the flange 9 near the guide trough 4. The side end of the flange 9 is connected to a cam 12 through an eccentric shaft. The side end of the cam 12 is connected to a second motor 13. A first spring 11 is connected between the flange 9 and the side wall of the guide trough 4. When the second motor 13 rotates, it drives the cam 12 to rotate eccentrically. The cam 12 drives the flange 9 to move up and down reciprocally, thereby driving the striking needle 10 to slide up and down reciprocally, so as to achieve the effect of high-frequency striking and blocking.

[0039] In some embodiments, such as Figure 3 and Figure 4 As shown, the anti-tilt cone plate 14 is slidably mounted on the walls of the guide trough 4 on both sides. Multiple sets of screws 15 are installed through the upper walls of both sides of the guide trough 4. The lower ends of the screws 15 are mounted on the upper walls of the anti-tilt cone plate 14. A second spring 16 is connected between the lower wall of the anti-tilt cone plate 14 and the bottom wall of the guide trough 4. Due to the different types of sealing, the height of the corrugated protrusions N is also different. By rotating the screws 15, the anti-tilt cone plate 14 is moved up and down so that the cone of the anti-tilt cone plate 14 is moved to the position where it is engaged with the corrugated protrusions N. This allows the anti-tilt cone plate 14 to be suitable for the production and assembly of various sealing applications. The second spring 16 pushes the anti-tilt cone plate 14 upward to keep the anti-tilt cone plate 14 fixed.

[0040] In some embodiments, such as Figure 3 and Figure 5 As shown, the anti-tilting cone plate 14 has an open cone 20 on the inner side near the end area. The opening direction of the open cone 20 faces the pre-compression cylinder 6. The end of the guide trough 4 has a discharge notch 17. The position of the discharge notch 17 is adapted to the open cone 20. When the plug moves to the end of the guide trough 4, in order to make the plug fall smoothly onto the port of the support and avoid the plug tilting during the fall, the distance between the two open cones 20 gradually increases and the cone height of the open cone 20 gradually decreases, thereby gradually reducing the engagement depth with the corrugated protrusion N on the plug. Finally, at the current angle, it automatically slides from the discharge notch 17 onto the support, avoiding the problem of the plug deviating from its angle when sliding.

[0041] In some embodiments, combined with Figure 6As shown, the anti-tilting cone plate 14 has an arc plate 21 at its end. The end of the arc plate 21 is set horizontally. The arc plate 21 can adjust the plug that slides down the guide chute 4 to a horizontal state so that it can cooperate with the horizontal conveying bracket and embed the plug into the bracket port.
