[0036] The core of the utility model is to provide a hinge shaft threading device, which realizes the shaft threading operation by alternating motion through a staggered shaft threading mechanism, thereby realizing the automatic and continuous production and processing of hinge shaft threading.

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the hinge threading device of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Combination Figure 1 , Figure 2 As shown, the utility model provides a hinge shaft threading device, including a hinge feeding mechanism 1, a shaft feeding mechanism 2, a staggered shaft threading mechanism 4 and other structures. The hinge feeding mechanism 1 is used to convey hinges to realize hinge supply. When conveying hinges, multiple hinges are conveyed in rows, and each hinge keeps the same state and moves in sequence. The shaft feeding mechanism 2 is used to supply the hinge shaft so that the hinge shaft moves along a straight line; the hinge shaft is a straight rod structure made of metal material, and the hinge shaft can be inserted into multiple hinges at one time to form a string.

[0039] It should be noted that a hinge generally includes two different leaf plates and a hinge shaft, and the two different leaf plates can rotate around the hinge shaft. For the convenience of explanation, except for this, the present invention uses "hinge" to refer to one of the leaf plates; the present invention is applied to the situation where the hinge shaft is inserted into a plurality of identical leaf plates, and another leaf plate is installed in the subsequent processing process.

[0040] The offset shaft threading mechanism 4 includes a hinge carrier 41 and an offset driver 42. The hinge carrier 41 is used to place hinges in rows so that each hinge maintains the same state. The shaft threading holes of each hinge are in a straight line and opposite to each other, and the hinge shaft can pass through. The offset driver 42 is used to drive the hinge carrier 41 to alternately reciprocate between the material receiving station and the shaft threading station, and perform different operations at the material receiving station and the shaft threading station. At the material receiving station, the hinge carrier 41 is opposite to the hinge feeding mechanism 1, and the hinge carrier 41 receives a number of hinges distributed in rows from the hinge feeding mechanism 1, and the hinges are arranged in a straight line on the hinge carrier 41. At the shaft threading station, the hinge carrier 41 is opposite to the shaft feeding mechanism 2, and the hinges arranged on the hinge carrier 41 are used to cooperate with the hinge shaft supplied by the shaft feeding mechanism 2. It should be noted that different types of hinges correspond to different hinge carriers 41. When changing styles, the corresponding hinge carrier 41 can be replaced.

[0041] The dislocation driver 53 drives the hinge carrier 52 to alternately reciprocate between the material receiving station and the shaft insertion station, receiving rows of hinges at the material receiving station and inserting hinge shafts at the shaft insertion station, and continuously alternately moves to realize the shaft insertion operation, thereby realizing the automatic continuous production and processing of hinge shaft insertion. When the shaft insertion is completed, the multiple hinges that have been inserted with the hinge shaft are removed together with the hinge shaft.

[0042] On the basis of the above scheme, the hinge threading device of the utility model further includes a hinge transfer mechanism 3, which is an active transfer structure and is used to move the hinge on the hinge feeding mechanism 1 to the hinge carrier 41. The hinge transfer mechanism 3 can transfer one hinge at a time or a row of hinges at a time.

[0043] Specifically, combined Figure 3 As shown, the hinge transfer mechanism 3 includes an auxiliary brush 31 and a transfer driver 32. The outer periphery of the auxiliary brush 31 is provided with cylindrical bristles. The auxiliary brush 31 is directly or indirectly mounted on the output shaft of the transfer driver 32. A reducer may be provided. The transfer driver 32 drives the auxiliary brush 31 to rotate. The rotation axis direction of the auxiliary brush 31 is perpendicular to the direction in which the hinge moves from the hinge feeding mechanism 1 to the hinge carrier 41. The auxiliary brush 31 is located above the hinge. When the hinge passes under the auxiliary brush 31, the bristles of the auxiliary brush 31 will contact the hinge and exert a sweeping force on the hinge to continue to move forward, brushing the hinge from the hinge feeding mechanism 1 to the hinge carrier 41. The auxiliary brush 31 provides further driving force for the hinge transfer process. The auxiliary brush 31 is used to drive one hinge each time. When the hinge passes under the auxiliary brush 31, a thrust is generated on the hinge to achieve further acceleration, thereby achieving the transfer of a single hinge. When a row of multiple hinges needs to be transferred simultaneously, multiple clamps can be set to clamp them simultaneously, and the transfer can be achieved by a mechanical arm or other mechanism.

[0044] Combination Figure 3 As shown, in a preferred embodiment, two sets of hinge transfer mechanisms 3 are sequentially arranged along the conveying direction of the hinge feeding mechanism 1, that is, two auxiliary brushes 31 are arranged in total, one of which is located at the junction of the hinge feeding mechanism 1 and the hinge carrier 41, and the other is located above the hinge feeding mechanism 1. The two auxiliary brushes 31 can rotate independently. The hinge transfer mechanism 3 at the rear can be provided with a lifting mechanism to independently control the lifting and lowering of the auxiliary brush 31. When the auxiliary brush 31 is lifted upward, it can stop working; the front auxiliary brush 31 is always working. When the number of hinges is small or the hinge is short, only the front auxiliary brush 31 can be used. When the number of hinges is large or the length of a single hinge is long, two auxiliary brushes 31 can be used at the same time.

[0045] Combination Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the hinge feeding mechanism 1 of the utility model comprises a hinge conveyor belt 11, a flat hinge push plate machine 12, a fan hinge push plate machine 13, a frame hinge vibration plate 141 and a frame hinge elevator 142. The hinge conveyor belt 11 is used to carry hinges and drive the hinges to translate. The hinge conveyor belt 11 is docked with the hinge carrier 41 at the material receiving station. The hinge conveyor belt 11 and the hinge carrier 41 are arranged in the same direction, and the hinge is transported from the hinge conveyor belt 11 to the hinge carrier 41 in a straight line. The flat hinge push plate machine 12 is used to provide flat hinges, the fan hinge push plate machine 13 is used to provide fan hinges, and the frame hinge vibration plate 141 and the frame hinge elevator 142 cooperate to provide frame hinges; flat hinges, fan hinges and frame hinges are three different types of hinges, each type of hinge is fed by different mechanisms, and the corresponding hinge can be placed on the hinge conveyor belt 11. It should be noted that the flat hinge push plate machine 12, the fan hinge push plate machine 13, the frame hinge vibration plate 141 and the frame hinge elevator 142 are used for the three types of hinge feeding equipment and can be set at the same time, or one of them can be selected and set separately.

[0046] Furthermore, the hinge threading device of the utility model also includes an orientation detector and an air blow rejector. The orientation detector is used to detect the orientation of the hinge during the conveying process, and the air blow rejector rejects the hinges with incorrect orientations to ensure that each hinge is fed in the same direction. The orientation detector and the air blow rejector can be arranged beside the hinge conveyor belt 11, or at the corresponding feeding positions of the flat hinge push plate machine 12, the fan hinge push plate machine 13, the frame hinge vibration plate 141 and the frame hinge elevator 142.

[0047] Combination Figure 2 , Figure 3 , Figure 5As shown, the shaft loading mechanism 2 includes a shaft push plate machine 21, a shaft conveying belt 22, a first feeding roller 23, a second feeding roller 24, a third feeding roller 25 and a shaft in-place detector 26. The shaft push plate machine 21 is used to output a hinge shaft, and the output hinge shaft is sequentially conveyed to the hinge carrier 41 located at the shaft threading station through the shaft conveying belt 22, the first feeding roller 12, the second feeding roller 13 and the third feeding roller 14. After the hinge shaft is output, it reaches the shaft conveying belt 22 and is driven by the shaft conveying belt 22 to continue to move forward; the first feeding roller 12, the second feeding roller 13 and the third feeding roller 14 are sequentially arranged along the moving direction of the hinge shaft, and the first feeding roller 12, the second feeding roller 13 and the third feeding roller 14 can rotate to form an effect of squeezing and moving the hinge shaft, so that the hinge shaft continues to move forward; when the hinge shaft passes through each hinge, the shaft threading is completed when the shaft in place detector 26 detects the shaft, and the shaft conveying belt 22, the first feeding roller 23, the second feeding roller 24 and the third feeding roller 25 stop moving. The shaft in place detector 26 can be a photoelectric sensor or an in place switch.

[0048] The movement forms of the dislocation drive 42 include two situations:

[0049] The first type: the offset driver 42 is used to drive the hinge carrier 41 to make horizontal displacement; the feeding directions of the hinge feeding mechanism 1 and the shaft feeding mechanism 2 are parallel; in the embodiment shown in the attached drawings of the utility model, the offset driver 42 is shown as a straight line as an example, and the moving direction of the offset driver 42 is perpendicular to the feeding directions of the hinge feeding mechanism 1 and the shaft feeding mechanism 2, and the feeding directions of the hinge feeding mechanism 1 and the shaft feeding mechanism 2 are parallel to each other. The offset driver 42 drives the hinge carrier 41 to move perpendicular to the feeding directions of the hinge feeding mechanism 1 and the shaft feeding mechanism 2, so that the hinge carrier 41 is aligned with the hinge feeding mechanism 1 or the shaft feeding mechanism 2.

[0050] The second type: the offset driver 42 is used to drive the hinge carrier 41 to rotate; the feeding directions of the hinge feeding mechanism 1 and the shaft feeding mechanism 2 form an angle. In this embodiment, it is only necessary to rotate the hinge carrier 41. The feeding directions of the hinge feeding mechanism 1 and the shaft feeding mechanism 2 are along the radial direction of the circumference, forming a certain central angle. When the hinge carrier 41 rotates, it can be connected to the hinge feeding mechanism 1 or the shaft feeding mechanism 2.

[0051] The utility model also includes a finished product discharging and transporting mechanism 5, which is used to take out the products with completed shaft threading from the hinge carrier 41 and place them on the finished product discharging trolley 6. The finished product discharging trolley 6 is provided with a plurality of stations for placing the products with completed shaft threading, and a plurality of products can be placed side by side.

[0052] Combination Figure 1 , Figure 2As shown, the finished product discharge and handling mechanism 5 includes a translation driver 51 and a material picking clamp 52. The material picking clamp 52 is installed at the output part of the translation driver 51. The translation driver 51 is used to drive the material picking clamp 52 to translate. The material picking clamp 52 is used to clamp the product with the shaft threaded from both ends. The clamp of the material picking clamp 52 can be lifted vertically and clamp the two ends of the hinge shaft respectively, driving the product with the shaft threaded to move from the hinge carrier 41 to the finished product discharge cart 6. An empty hinge carrier 41 can repeatedly receive new hinges and complete the shaft threading operation.
