Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic screw feeding device. Background Art

[0002] At present, the injection molding and rubber coating of screws all rely on manual operation to place the screws in the injection mold. After the injection molding is completed, the finished product and the sprue need to be manually removed from the mold and placed in different material boxes. The production efficiency is extremely low, the labor intensity of the workers is very high, and the cost of the product is very high. At the same time, injection molding production requires manual operation, which can easily have an adverse effect on the lives and property of the workers. Due to long working hours, workers will become tired during the production process and are prone to misoperation, which may cause damage to the mold and seriously affect the normal production. The utility model CN210233768U discloses an automatic loading and unloading device for screw rubber coating, which can realize the removal and separation of the finished product and the sprue, and realize unmanned production. This not only improves production efficiency but also reduces labor costs, greatly reducing product costs. However, in this solution, on the one hand, the screw loading adopts a one-by-one transmission method, which reduces production efficiency. On the other hand, the number of screws that the robot can clamp at one time is only 1 to 2, and the transmission efficiency is low, resulting in low efficiency in batch production. Utility Model Content

[0003] The utility model discloses an automatic screw feeding device, which aims to solve the problem of low efficiency of the existing manipulator feeding mechanism.

[0004] The utility model adopts the following scheme:

[0005] The lifting mechanism is suitable for lifting all the screws when the robot picking mechanism picks up the materials so that the robot picking mechanism can grab the materials; the robot picking mechanism includes a robot and a picking clamp, and the picking clamp is provided with a plurality of clamp assemblies for clamping all the screws on the picking plate and transporting them to the downstream process.

[0006] Furthermore, the spacing between the conveying slots of the first conveying track and the second conveying track is equal to the spacing between three adjacent material receiving slots, and the double-track conveying mechanism conveys two screws to the two spaced material receiving slots at the same time in an interlaced manner.

[0007] Furthermore, the material picking fixture includes two rows of fixture groups formed by arranging a plurality of the fixture components, and the spacing between two adjacent fixture components in each row of the fixture group is equal to the spacing between three adjacent material receiving troughs, so as to respectively clamp the spaced screws out from the swing plate.

[0008] Furthermore, the material removal fixture is also provided with two rows of suction cup assemblies for removing the processed screws after the downstream processing is completed, and the arrangement spacing of the suction cup assemblies is the same as the arrangement spacing of the fixture group.

[0009] Furthermore, the suction cup assembly is connected to a telescopic cylinder, and the telescopic cylinder is suitable for driving the suction cup assembly to telescope.

[0010] Furthermore, a material blocking mechanism is provided at the end of the double-track conveying mechanism to control the output of the screws at the end of the double-track conveying mechanism.

[0011] Furthermore, the material blocking mechanism includes a transverse stopper provided below the double-track conveying mechanism, and the transverse stopper is suitable for blocking the first conveying track and the second conveying track to block the output of the screws.

[0012] Furthermore, it also includes a material unloading mechanism, which includes a material receiving slide rail and a magnetic roller assembly line. The material receiving slide rail is suitable for receiving the processed screws transported by the suction cup assembly of the manipulator material picking mechanism, and the magnetic roller assembly line is suitable for unloading the processed screws.

[0013] Beneficial effects:

[0014] This solution can simultaneously transmit two screws to the swing plate by setting up a double-track transmission mechanism. The spacing between adjacent receiving slots on the swing plate is smaller than the spacing between the two transmission tracks, and the spacing between the two transmission tracks is equal to the spacing between three adjacent receiving slots, so that staggered loading can be achieved, and more intensive material swinging can be achieved on the swing plate, which solves the influence of the spacing of the transmission track arrangement on the swing material spacing, and more screws can be placed on the swing plate to improve the loading efficiency.

DETAILED DESCRIPTION

[0020] Combine Figures 1 to 4 As shown, this embodiment provides a screw automatic feeding device, comprising: a vibration plate 1, a double-track conveying mechanism 2, a swinging mechanism 3, and a manipulator picking mechanism 4; wherein, the double-track conveying mechanism 2 is connected to the vibration plate 1, and comprises a first conveying track 21 and a second conveying track 22 arranged in parallel; the first conveying track 21 and the second conveying track 22 are suitable for synchronously conveying two rows of screws 6 to the swinging mechanism 3; the swinging mechanism 3 comprises a transverse mechanism 32, a swinging plate 31 arranged on the transverse mechanism 32, and a lifting mechanism 33 arranged below the swinging plate 31, wherein the transverse mechanism 32 is suitable for Drive the swing plate 31 to move gradually in front of the discharge port of the first conveying track 21 and the second conveying track 22; a plurality of receiving troughs facing the double-track conveying mechanism 2 are arranged at equal intervals on the swing plate 31 to receive the screws 6 transported from the double-track conveying mechanism; the lifting mechanism 33 is suitable for lifting all the screws when the manipulator picking mechanism 4 picks up the material so as to facilitate the manipulator picking mechanism 4 to clamp them; the manipulator picking mechanism 4 includes a manipulator and a picking clamp, and the picking clamp is provided with a plurality of clamp assemblies 421 for clamping all the screws 6 on the swing plate 31 and transporting them to the downstream process.

[0021] In this embodiment, the screw 6 includes a screw head and a screw rod. An injection molding device is provided at the downstream end of the automatic screw feeding device for injection molding the screw head to form an adjustable foot product. The injection molding device is an existing device capable of injection molding the screw head, and its structure and principle are not further described.

[0022] Combine Figures 1 to 3As shown, in this embodiment, the vibrating plate 1 is a conventional device, connected to a dual-track conveyor mechanism for synchronously conveying two sets of screws 6. The dual-track conveyor mechanism includes a first conveyor track 21 and a second conveyor track 22. Each of the first and second conveyor tracks 21 and 22 is provided with a transmission slot 23. After being acted upon by the vibrating plate 1, the screws 6 enter the transmission slot 23, with the screw heads emerging from the slot and the screw shafts extending below the slot. During the vibration process, the screws 6 are gradually conveyed toward the ends of the conveyor tracks. The first and second conveyor tracks 21 and 22 can be tilted downward toward the swing mechanism 3 to facilitate downward conveyance of the screws 6 to the swing mechanism 3. A stopper mechanism 24 is provided at the ends of the first and second conveyor tracks 21 and 22 to control the delivery of the screws. Specifically, the stopper mechanism 24 includes a transverse stopper disposed below the dual-track conveyor mechanism. The transverse stopper is adapted to block the delivery slots of the first and second conveyor tracks 21 and 22 to prevent the delivery of the screws 6. This solution can control the output of screws as needed, and can also prevent the mechanism from getting stuck due to continued output of screws 6 after the swing mechanism 3 is filled with screws 6.

[0023] Combine Figures 2 to 3As shown, the swing mechanism 3 includes a transverse movement mechanism 32, a swing plate 31 disposed on the transverse movement mechanism 32, and a lifting mechanism 33 disposed below the swing plate 31. The transverse movement mechanism 32 is equipped with a servo motor for driving the swing plate 31 to achieve step-by-step movement. The swing plate 31 is disposed in front of the end position of the dual-track conveyor mechanism 2. An open swing trough 311 is provided on the side of the swing plate 31 facing the dual-track conveyor mechanism 2. The height of the swing plate 31 is the same as that of the conveyor trough and is close to the conveyor trough. The sliding direction of the swing plate 31 is perpendicular to the transmission direction of the screw 6. When the swing trough 311 moves to align with the conveyor trough, the screw 6 enters the swing trough 311. The swing plate 31 continues to move, aligning the rear swing troughs 311 with the conveyor trough one after another, so that each swing trough 311 is filled with a screw 6. In this embodiment, the distance between the first conveying track 21 and the second conveying track 22 is equal to the distance between three adjacent material receiving troughs, and the double-track conveying mechanism 2 conveys two screws to the two spaced material receiving troughs at the same time in an interlaced manner. When the first material trough 31 is moved to align with the first conveying track 21, the transverse stop block is moved away to allow the screw 6 to be output. At this time, the first conveying track 21 and the second conveying track 22 align the first material trough with the third material and convey a screw 6 respectively. Then the material trough 31 moves forward by the spacing of the material trough 311, so that the second material trough is aligned with the first conveying track 21. At this time, the second conveying track 22 is aligned with the fourth conveying track, and the loading of the first four material troughs 311 is completed. Then the material trough 31 continues to move until the fifth material trough is aligned with the first conveying track 21, and the cycle is repeated until screws 6 are placed in all the material troughs 311. Through this setting, the dual-track conveying mechanism 2 can load materials at the same time, and the distance between the swing troughs 311 can be smaller than the distance between the first conveying track 21 and the second conveying track 22, so that more swing troughs 311 can be arranged on the same swing plate 31 to place more screws 6 at the same time, which helps to improve efficiency.

[0024] After the swing plate 31 is filled with screws 6, it moves to the material picking area of ​​the manipulator material picking mechanism 4 under the drive of the transverse movement mechanism 32. At this time, the lifting mechanism 33 arranged under the swing plate 31 works to lift all the screws to a preset height so that the screw heads are exposed on the surface of the swing plate 31 to facilitate subsequent grabbing.

[0025] Combine Figure 4As shown, the material picking fixture includes two rows of fixture groups formed by arranging a plurality of the fixture components 421, and the spacing between two adjacent fixture components 421 in each row of fixture groups is equal to the spacing between three adjacent material receiving troughs, so as to respectively clamp the spaced screws 6 from the swing plate 31. The two rows of fixture groups are defined as the first row of fixture groups and the second row of fixture groups 42. The fixture components 421 on the two rows of fixture groups are arranged relative to each other, and the distance between adjacent fixture components 421 is equal to the distance between three adjacent material receiving troughs. When clamping, the first row of fixture groups can simultaneously clamp the screws on the first swing trough, the third swing trough, the fifth swing trough, ... After the first row of fixture groups is clamped, the manipulator controls the material picking fixture to move a certain distance so that the second row of fixture components aligns with the screws on the second swing trough, the fourth swing trough, the sixth swing trough, ... and clamps them, thereby achieving the effect of clamping all the screws on the swing plate 31 at one time, thereby improving the efficiency of clamping. In this embodiment, the manipulator can be an existing five-axis manipulator, etc., for controlling the material picking fixture to switch between the swing plate 31 and the injection molding equipment to achieve material handling. In this embodiment, the clamp assembly 421 can be an existing pneumatic clamp, which is an existing design and will not be described here.

[0026] In one embodiment, the material removal fixture is further provided with two rows of suction cup assemblies 43 for removing the processed screws after the injection molding equipment is completed. The arrangement spacing of the suction cup assemblies 43 is the same as the arrangement spacing of the fixture group. Specifically, a plurality of suction cup devices are arranged on the suction cup assembly 43, and the spacing between adjacent suction cup devices is the same as the spacing between adjacent fixture assemblies. The suction cup assembly 43 is arranged on the opposite side of the fixture group so that the two do not affect each other, and the switching of the suction cup assembly 43 and the fixture group is controlled by the rotation of the manipulator. Preferably, the suction cup assembly 43 is connected to a telescopic cylinder 44, and the telescopic cylinder 44 is suitable for driving the suction cup assembly 43 to telescope, so that the suction cup assembly 43 has a larger movable stroke.

[0027] This embodiment also includes a material unloading mechanism, which includes a material receiving slide 51 and a magnetic roller assembly line 52. The material receiving slide 51 is suitable for receiving the processed screws transported by the suction cup assembly 43 of the manipulator material picking mechanism 4, and the magnetic roller assembly line is suitable for unloading the processed screws.

[0028] Through the solution of this embodiment, the efficiency of loading screws can be improved, more screws can be loaded at one time in a smaller space, and the efficiency of screw plastic coating is improved.
