Description

Technical Field

[0001] This invention relates to a fastener processing apparatus, and more particularly to a processing apparatus capable of continuously applying liquid adhesive to fasteners. Background Technology

[0002] Please refer to the following: Figure 6 As shown, the existing fastener liquid adhesive coating and conveying device uses a conveyor belt 91 to transport the fastener F to be coated with liquid adhesive to a coating mechanism 92. Then, a camera 93, together with a PLC (Programmable Logic Controller), performs visual positioning of the fastener F. After positioning, the PLC controls the coating mechanism 92 to accurately apply liquid adhesive to the fastener F based on the visual positioning result.

[0003] When using camera 93 for visual positioning, fastener F needs to be completely stationary. Therefore, in practice, the conveyor belt 91 transports a batch of fasteners F to be coated with glue to the bottom of the glue coating mechanism 92 and then gradually slows down. After the fasteners F are completely stationary, the camera 93 takes a picture first, and then the PLC judges the glue coating path before the glue coating action can be performed. Then the same operation is performed on the next batch of fasteners F to be coated with glue.

[0004] However, waiting for the fastener F to decelerate to a standstill, and the actions of taking pictures and judging the glue application path take a certain amount of time. This causes the existing coating conveyor to often be in a waiting state and unable to perform glue application continuously, which in turn leads to a reduction in production capacity.

[0005] Therefore, the existing fastener liquid adhesive coating and conveying device needs to be improved. Summary of the Invention

[0006] In view of the aforementioned shortcomings and deficiencies of the prior art, the present invention provides a fastener pre-coating continuous coating conveying device capable of performing glue application without interruption to improve production capacity.

[0007] To achieve the aforementioned objectives, the present invention employs a design of a fastener pre-coating continuous coating and conveying device for processing a plurality of fasteners. This fastener pre-coating continuous coating and conveying device comprises:

[0008] Two conveying mechanisms are arranged side by side, each conveying the fastener from its input end to its output end;

[0009] A magnetic turntable mechanism, comprising two adjacent conveying mechanisms, and including:

[0010] A turntable is located above the two input ends of the two conveying mechanisms;

[0011] Several magnetic components are spaced apart along the periphery of the turntable, and each magnetic component is used to attract fasteners;

[0012] A drive device is connected to the turntable and can drive the turntable to rotate in a forward or reverse direction, wherein the forward and reverse directions are opposite to each other.

[0013] Two separators are respectively located at the two input ends of the two conveying mechanisms and are respectively close to the opposite sides of the turntable;

[0014] When the turntable rotates in the forward direction, one of the separating components is used to separate the fasteners adsorbed on the magnetic components from the magnetic components and transfer them to the corresponding conveying mechanism; when the turntable rotates in the reverse direction, another separating component is used to separate the fasteners adsorbed on the magnetic components from the magnetic components and transfer them to the corresponding conveying mechanism.

[0015] A flat conveying mechanism for conveying fasteners toward the periphery of the turntable of the magnetic turntable mechanism;

[0016] A stop mechanism is provided on the flat conveying mechanism and can prevent or allow the fasteners on the flat conveying mechanism to move toward the turntable;

[0017] A vision positioning component is positioned above the two conveying mechanisms and is used to measure the position of the fasteners on the two conveying mechanisms;

[0018] The adhesive application mechanism can move back and forth above the two conveying mechanisms and apply adhesive to the fasteners on the two conveying mechanisms based on the measurement results of the vision positioning component.

[0019] For ease of identification, the two conveying mechanisms will be referred to as the first conveying mechanism and the second conveying mechanism, respectively. In use, the flat conveying mechanism transports the fasteners to be glued to the periphery of the turntable of the magnetic turntable mechanism. The turntable rotates in one of two directions, either forward or reverse. Through the rotation of the turntable, the cooperation of the magnetic components around the turntable, one of the separating components, and the stop mechanism, a specific number of fasteners are moved from the flat conveying mechanism to the first conveying mechanism for visual positioning and glue application. When the glue application mechanism applies glue to the fasteners on the first conveying mechanism, the turntable rotates in the other direction to guide the fasteners to the second conveying mechanism for visual positioning. Once the fasteners on the first conveying mechanism have been glued, the glue application mechanism can immediately move to the second conveying mechanism to continue the glue application process.

[0020] The advantage of this invention is that by setting up two conveying mechanisms and a magnetic turntable mechanism, when the fastener on one of the conveying mechanisms is still being glued, the magnetic turntable mechanism can convey the fastener to the other conveying mechanism for pre-visual positioning, so that the glue-applying mechanism can continuously apply glue to the fastener, thereby increasing production capacity.

[0021] A further improvement of the fastener pre-coating continuous coating conveying device of the present invention is that the magnetic component of the magnetic turntable mechanism is a permanent magnet, which is embedded in the side of the turntable.

[0022] A further improvement of the fastener pre-coating continuous coating conveying device of the present invention is that: the turntable of the magnetic turntable mechanism is a disc; the width of the separator of the magnetic turntable mechanism decreases toward the tip of the separator, and the tip is close to the turntable.

[0023] A further improvement of the fastener pre-coating continuous coating conveying device of the present invention is that: a guide groove is formed in the flat conveying mechanism, one end of the guide groove is adjacent to the periphery of the turntable of the magnetic turntable mechanism, and the guide groove is used for the fastener to slide through; the stop mechanism has: a cylindrical body disposed in the flat conveying mechanism; and a rod body that can slide through the cylindrical body and can pass through the guide groove of the flat conveying mechanism to prevent the fastener on the flat conveying mechanism from moving toward the turntable.

[0024] A further improvement of the fastener pre-coating continuous coating conveying device of the present invention is that it has a removal mechanism that can move back and forth above the two conveying mechanisms and can remove the fastener coated with adhesive from the two conveying mechanisms.

Detailed Implementation

[0031] Please see Figures 1 to 3 As shown, the fastener pre-coating continuous coating conveyor can process several fasteners F, which are preferably magnetic screws. The fastener pre-coating continuous coating conveyor includes two conveying mechanisms 10, a magnetic turntable mechanism 20, a flat conveying mechanism 30, a stop mechanism 40, a vision positioning component 50, and an adhesive application mechanism 60; and in this embodiment, it further includes a removal mechanism 70.

[0032] The two conveying mechanisms 10 mentioned above are arranged side by side, and each conveying mechanism 10 can convey the fastener F from its input end 11 to its output end 12. Specifically, each conveying mechanism 10 is a straight conveyor belt, and the long sides of the two conveying mechanisms 10 are preferably parallel to each other. For ease of explanation, the two conveying mechanisms 10 are respectively named the first conveying mechanism 101 and the second conveying mechanism 102.

[0033] The aforementioned magnetic turntable mechanism 20 is adjacent to the conveying mechanism 10 and includes a turntable 21, a plurality of magnetic components 22, a drive device 23, and two separating components 24. The turntable 21 is located above and between the two input ends 11 of the two conveying mechanisms 10; the turntable 21 is preferably a disc. The magnetic components 22 are spaced apart along the periphery of the turntable 21, and each magnetic component 22 can attract fasteners F, thereby the turntable 21 can attract and fix multiple fasteners F at specific intervals to the side 211 of the turntable 21 by means of the magnetic components 22. Each magnetic component 22 is preferably a permanent magnet, which is embedded in the side 211 of the turntable 21, but the magnetic components 22 are not limited to permanent magnets, as long as they can generate magnetic force to attract fasteners F, for example, they can be electromagnets, or permanent magnets with a magnetic force greater than that of ferrite magnets, such as various rare earth magnets. If the fastener is non-magnetic or weakly magnetic, it can be transferred using, for example, a divider combined with a disc with equally spaced angles.

[0034] Please refer to the following: Figure 1 , Figure 3 and Figure 4 As shown, the drive device 23 is connected to the turntable 21 and can drive the turntable 21 in a forward direction D1 to a reverse direction D2 (e.g., Figure 4As shown, the forward direction D1 and the reverse direction D2 are opposite to each other. Specifically, the drive device 23 is a servo motor, and the forward direction D1 and the reverse direction D2 are counterclockwise and clockwise, respectively.

[0035] Two separators 24 are respectively located at the two input ends 11 of the two conveying mechanisms 10, and are respectively adjacent to opposite sides of the turntable 21. Specifically, each separator 24 is a block, one separator 24 is fixed to the outer frame of the first conveying mechanism 101, and the other separator 24 is fixed to the outer frame of the second conveying mechanism 102. Both separators are located above the belt of the corresponding conveying mechanism 10 but do not move with the belt. In addition, the separator 24 being adjacent to the turntable 21 means that there is still a gap between the separator 24 and the turntable 21, and the separator 24 will not rotate with the turntable 21. The width of each separator 24 preferably decreases towards the tip 241 of the separator 24, and the tip 241 is adjacent to the turntable 21.

[0036] When turntable 21 rotates in the positive direction D1, the attracted fastener F and the magnetic element 22 move together around the center of turntable 21 until they contact one of the separating elements 24 (i.e., Figure 3 The lowermost separator 24) extends to the tip 241. Upon contact with the tip 241, the gap between the fastener F and the turntable 21 is inserted by the tip 241, and the gap gradually widens due to the pushing action of the tip 241, thereby causing the fastener F to separate from the magnetic member 22 and transfer to the belt of the first conveying mechanism 101. When the turntable 21 rotates in the reverse direction D2, another separator 24 causes the fastener F, which is attracted to the magnetic member 22, to separate from the magnetic member 22 and transfer to the belt of the second conveying mechanism 102.

[0037] The aforementioned flat conveying mechanism 30 conveys the fastener F to be coated with adhesive toward the periphery of the turntable 21 of the magnetic turntable mechanism 20. Specifically, a guide groove 31 is formed in the flat conveying mechanism 30. One end of the guide groove 31 is adjacent to the periphery of the turntable 21 of the magnetic turntable mechanism 20. The fastener F can slide through the guide groove 31 and move sequentially along the guide groove 31 to the periphery of the turntable 21 and is attracted by the magnetic component 22.

[0038] The aforementioned stop mechanism 40 is disposed on the flat conveying mechanism 30 and can prevent or allow the fastener F on the flat conveying mechanism 30 to move toward the turntable 21. Specifically, the stop mechanism 40 has a cylindrical body 41 and a rod 42. The cylindrical body 41 is disposed on the flat conveying mechanism 30; the rod 42 slidably passes through the cylindrical body 41 and can, as appropriate, pass into the guide groove 31 of the flat conveying mechanism 30 to prevent the fastener F on the flat conveying mechanism 30 from moving toward the turntable 21 (e.g., ...). Figure 3 (as shown), or retract the cylinder body 41 to allow the fastener F on the flat conveying mechanism 30 to move toward the turntable 21 (as shown). Figure 4 (As shown). In this embodiment, the stop mechanism 40 is a cylinder.

[0039] The aforementioned visual positioning component 50 is positioned above the two conveying mechanisms 10 and measures the position of the fasteners F on the two conveying mechanisms 10. Specifically, the visual positioning component 50 includes a camera and a computing module. The camera is positioned above the two conveying mechanisms 10 to capture a complete image of the fasteners F on the two conveying mechanisms 10. The image is then sent to the computing module to determine the precise position of the fasteners F and to plan the action path of the glue application mechanism 60.

[0040] Please refer to the following: Figures 3 to 5 As shown, the aforementioned adhesive application mechanism 60 can move back and forth above the two conveying mechanisms 10, and can apply adhesive to the fasteners F on the two conveying mechanisms 10 according to the measurement results of the vision positioning component 50. The aforementioned removal mechanism 70 can move back and forth above the two conveying mechanisms 10, and can remove the fasteners F coated with adhesive from the two conveying mechanisms 10. The adhesive application mechanism 60 and the removal mechanism 70 are standard components in the prior art, so their details will not be described further.

[0041] The operation of this invention is as follows:

[0042] Please refer to the following: Figure 3 As shown, shortly after the process starts, the first batch of fasteners F in the process has been conveyed to the second conveying mechanism 102. When the gluing mechanism 60 applies glue to the first batch of fasteners F on the second conveying mechanism 102, the flat conveying mechanism 30 conveys the second batch of fasteners F to the periphery of the turntable 21 of the magnetic turntable mechanism 20. The turntable 21 rotates in the positive direction D1. With the rotation of the turntable 21 and the cooperation of the magnetic components 22 on the periphery of the turntable 21, one of the separating components 24 and the stop mechanism 40, the second batch of fasteners F moves towards the first conveying mechanism 101 via the turntable 21. The fasteners F are separated from the magnetic components 22 and fall onto the first conveying mechanism 101 by the push of the tip 241 of the separating component 24. After this batch of fasteners F has completely entered the first conveying mechanism 101 and been conveyed to a specific position, the first conveying mechanism 101 will stop conveying. Then, the visual positioning component 50 measures the precise position of the fasteners F on the first conveying mechanism 101.

[0043] Please refer to the following: Figure 4As shown, since the fasteners F on the first conveying mechanism 101 have already completed visual positioning, after the gluing mechanism 60 completes the gluing action on all the fasteners F on the second conveying mechanism 102, it immediately moves above the first conveying mechanism 101 to continue gluing the fasteners F. At this time, the next batch (third batch) of fasteners F moves towards the second conveying mechanism 102 via the turntable 21. After this batch of fasteners F has completely entered the second conveying mechanism 102 and been conveyed to a specific position, the removal mechanism 70 removes the fasteners F coated with adhesive from the second conveying mechanism 102. In this embodiment, the removal mechanism 70 is a gripper. After this batch of fasteners F coated with adhesive has completely entered the gripping range of the removal mechanism 70, the removal mechanism 70 grips the fasteners F and moves them to the next process.

[0044] Please refer to the following: Figure 5 As shown, after the gluing mechanism 60 completes the gluing action on all the fasteners F on the first conveying mechanism 101, it moves again to the top of the second conveying mechanism 102 to continue gluing the fasteners F. At this time, the next batch of fasteners F moves towards the first conveying mechanism 101 via the turntable 21. After this batch of fasteners F has completely entered the first conveying mechanism 101 and been conveyed to a specific position, the removal mechanism 70 moves to the top of the first conveying mechanism 101 and removes the fasteners F coated with glue.

[0045] In summary, by setting up two conveying mechanisms 10 and a magnetic turntable mechanism 20, when the fastener F on one of the conveying mechanisms 10 is still being glued, the magnetic turntable mechanism 20 can transport the fastener F to the other conveying mechanism 10 for pre-visual positioning, so that the glue application mechanism 60 can continuously and uninterruptedly apply glue to the fastener F, thereby increasing production capacity.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
