Description

Technical Field

[0001] The utility model relates to the technical field of hinge assembly, in particular to an assembly tool for hinges and a production line using the assembly tool. Background Art

[0002] A hinge is a mechanical device used to connect two relatively independent solids and enable them to rotate relative to each other. A hinge is a very common furniture door connector. It uses the principle of movable hinges to allow the door to be opened or closed around an axis. In the current hinge processing, due to the increasingly high performance requirements for hinges, it is necessary to assemble more hinge parts to form a finished hinge. The hinge is mainly assembled from a cup head, a rocker arm, an arm body, a base, a U-shaped nail, an inner bar assembly, a torsion spring, a plastic round tube, a number of connecting nails and screws.

[0003] A hinge with a door opening angle of 90 degrees, which makes the two door panels parallel to each other at 180 degrees after closing, and the opening angle is 90 degrees, that is, it can be used on cabinets with two consecutive doors connected in parallel, or on cabinets with a fixed section at one end of the door panel, and is also widely used for the inner cover connection of corner cabinet doors. When the cup head and the arm body are hinged and fixed, it is difficult to fix the arm body and the torsion spring, resulting in low production efficiency, long production cycle, low positioning accuracy, and difficulty in ensuring the yield rate. Therefore, it is necessary to design an assembly vehicle suitable for the hinge, which can bear the carrier of parts such as rocker arms, torsion springs, inner bar components, cup heads, U-shaped nails, etc. The carrier serves as a carrier for placing the hinge, and each position can be accurately positioned.

[0030] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] As Figures 1-6 shown, an assembly carrier 1 of a hinge 2, the hinge 2 includes an arm body 21 and a cup head 22, and includes a base 11, a limiting member 12 and a stopper 13. The base 11 has a positioning surface adapted to the surface shapes of the arm body 21 and the cup head 22. The stopper 13 is fixedly arranged on both sides of the base 11, and the limiting member 12 is movably arranged on both sides of the base 11. The base 11, the limiting member 12 and the stopper 13 jointly form a groove for accommodating the hinge 2.

[0032] As Figures 1-6 shown, the positioning surface includes a cup head positioning surface 111 and an arm body positioning surface 112. The cup head positioning surface 111 is arranged at the front part of the base 11. The cup head positioning surface 111 has a convex surface 1111, and the cup part 221 of the cup head 22 is buckled on the convex surface 1111. The arm body positioning surface 112 is arranged at the middle and rear parts of the base 11. The arm body positioning surface 112 includes a curved surface 1121 and an inclined surface 1122. The curved surface 1121 and the inclined surface 1122 are respectively adapted to the surface shapes of the bending part 211 and the straight rod part 212 of the arm body 21. The positioning surface further includes a vertically arranged rocker arm positioning surface 113. The rocker arm positioning surface 113 is vertically connected to the cup head positioning surface 111 and the arm body positioning surface 112, and the rocker arm positioning surface 113 is adapted to the surface shape of the rocker arm 23 of the hinge 2. The carrier includes a cup head positioning surface 111, an arm body positioning surface 112 and a rocker arm positioning surface 113, and can accommodate the whole hinge 2. In the production line applying the assembly carrier 1, the whole hinge 2 can be assembled on the assembly carrier 1 without changing the carrier due to assembling some parts halfway.

[0033] As Figure 1 , 3As shown in FIGS. 3 and 4, the limiting member 12 includes a torsion spring limiting block 121 and an arm body limiting block 122. The torsion spring limiting block 121 is used to limit the torsion spring 24 to a preset position, and the arm body limiting block 122 is used to limit and fix the arm body 21 on the assembly carrier 1. The torsion spring limiting block 121 is in an "L" shape and includes a first sliding end 1211 and a first limiting end 1212 that are vertically connected. The first sliding end 1211 is slidably disposed on the base 11, and the first limiting end 1212 has a first extension portion 1213 facing the base 11 to limit the torsion spring 24 of the extension portion limiting hinge 2 to a preset position. The arm body limiting block 122 is in an "L" shape and includes a second sliding end 1221 and a second limiting end 1222 that are vertically connected. The second sliding end 1221 is slidably disposed on the base 11, and the second limiting end 1222 has a second extension portion 1223 facing the base 11. The second extension portion 1223 limits the arm body 21 within the base 11. After the assembly carrier 1 is placed into the hinge 2, the torsion spring limiting block 121 and the arm body limiting block 122 respectively clamp the torsion spring 24 and the arm body 21 of the hinge 2. The torsion spring limiting block 121 limits the torsion spring 24 to a preset position for subsequent processes. The arm body limiting block 122 cooperates with the stop block 13 to limit and fix the arm body 21 on the base 11 from different directions, so that the hinge 2 is not easily slid during the assembly process.

[0034] As Figure 2 and 5 shown, the stop block 13 includes a first stop block 131 and a second stop block 132. The first stop block 131 is symmetrically disposed on both sides of the bent portion 211, and the second stop block 132 is symmetrically disposed on both sides of the straight rod portion 212. A positioning post 14 is provided on the base 11, and the positioning post 14 is adapted to the positioning hole 213 of the arm body 21. The stop block 13 abuts against both sides of the arm body 21 to prevent the hinge 2 from falling during the operation of the production line. By positioning the arm body 21 with the positioning post 14, the compatibility with the same type of hinge 2 is high, and there is no need to replace the assembly carrier 1 for different hinges 2. Taking the arm body 21 as the carrier for accommodating the hinge 2 parts, the assembly carrier 1 only needs to meet the requirement that the positioning post 14 coincides with the product positioning hole 213, so it can be universal without re-designing the assembly carrier 1, which greatly saves the rework cost and time and better meets the production requirements.

[0035] As Figure 7 and 8As shown in the figure, a production line uses the assembly carrier 1 of any of the above technical solutions. The production line further includes a fixing member 3 that can be lifted and arranged above the assembly carrier 1 and an unlocking member 4 that can be telescopically arranged on both sides of the assembly carrier 1. The fixing member 3 includes a first fixing block 31 and a second fixing block 32. When the first fixing block 31 and the second fixing block 32 descend, they respectively press the cup head 22 and the arm body 21 of the hinge 2. The unlocking member 4 includes a first unlocking block 41 and a second unlocking block 42. The first unlocking block 41 and the second unlocking block 42 are respectively arranged on both sides of the assembly carrier 1. When the first unlocking block 41 and the second unlocking block 42 extend, they respectively push the torsion spring limiting block 121 and the arm body limiting block 122 to unlock the hinge 2, and the hinge 2 can be taken out in the next process.
