Description

Technical Field

[0001] This utility model relates to the field of automatic watch buckle assembly, and more specifically to a watch buckle assembly feeding mechanism. Background Technology

[0002] During the watch manufacturing process, the clasps need to be fed and assembled. Usually, a vibratory feeder is used in the conveying process. The working principle of the vibratory feeder is to automatically sort the clasps through a frequency converter and a motor, so that the clasps can be conveyed neatly. Then, the clasps that are in contact with each other are conveyed by a belt or chain conveyor line. Finally, the individual clasps are pushed into the assembly equipment for assembly.

[0003] However, in the existing buckle assembly feeding mechanism, the conveying of several buckles in contact with each other during the conveying process causes the buckle at the conveying head end to easily come into contact with the conveying end of the cylinder when the cylinder pushes the buckle into the assembly equipment. This causes the position of the previous buckle to shift, resulting in the buckle being conveyed crookedly and making it impossible to assemble. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a buckle assembly feeding mechanism to solve the problem in the background art that the previous buckle at the conveying head end is prone to contact with the cylinder conveying end, causing the position of the previous buckle to be offset, resulting in the subsequent buckle being conveyed crookedly and unable to be assembled.

The rotating mechanism is located at the bottom of the extension plate, and one end of the rotating mechanism is in contact with the bottom of the squeezing mechanism, and the other end extends into the inside of the conveyor table and is in contact with the bottom of the limiting mechanism.

[0006] Furthermore, the conveying mechanism includes a conveyor belt, a connecting channel, a conveying channel, and a motor. The conveyor belt is installed on the top of the conveying platform, and one end of the conveyor belt extends to the outside of the conveying platform. A connecting channel is provided on the top of the conveying platform near the end of the conveyor belt. A conveying channel communicating with the connecting channel is provided on one side of the top of the conveying platform. A motor connected to the drive shaft of the conveyor belt is installed on one side of the conveying platform.

[0007] Furthermore, the pushing mechanism includes a mounting plate, a cylinder, a slide groove, a sliding plate, and a push plate. The mounting plate is fixedly connected to the top of the extension plate. A cylinder is installed at the top of the mounting plate. A slide groove is opened on one side of the mounting plate. A push plate is fixedly connected to the output end of the cylinder. A sliding plate is fixedly connected to one side of the push plate near the inside of the slide groove.

[0008] Furthermore, the extrusion mechanism includes a guide plate, a guide block, a pressure rod, and a support spring. The top of the extension plate has an installation hole near the left side of the extrusion pusher. The guide plate is slidably connected inside the installation hole. The top of the guide plate is fixedly connected to a guide block that passes through the installation hole. The bottom of the guide plate is fixedly connected to a pressure rod that passes through the installation hole. A support spring is sleeved on the outside of the pressure rod. The bottom end of the support spring is fixedly connected to the bottom of the installation hole, and the other end is fixedly connected to the bottom of the guide plate.

[0009] Furthermore, the limiting mechanism includes a movable plate, a positioning block, a support plate, a tension spring, a connecting rod, and a pressure plate. A movable groove is provided on one side of the conveyor table near the outer side of the rotating mechanism. A receiving groove communicating with the movable groove is provided inside the conveyor table. The top of the receiving groove communicates with the surface of the conveying mechanism. Two limiting grooves are provided inside the receiving groove, and the two limiting grooves are symmetrically arranged. The two sides of the movable plate are slidably connected to the two limiting grooves respectively. A positioning block passing through the top of the receiving groove is fixedly connected to the top of the movable plate. Two support plates are fixedly connected to the inner wall of the receiving groove, and the two support plates are symmetrically arranged.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. In this utility model, when several watch buckles are conveyed to the connecting channel via a conveyor belt and reach the connection between the connecting channel and the conveying channel, a cylinder can drive the push plate and the slide plate to move. When the push plate and the slide plate contact the guide block, the guide block compresses the support spring through the guide plate. The pressure rod drives one end of the rotating plate to rotate downwards, and the other end drives the pressure plate to move upwards. At this time, under the action of the connecting rod and the moving plate, the pressure rod drives the positioning block to pass through the connecting channel. At this time, the moving plate drives the tension spring to stretch, and the positioning block is locked inside the previous watch buckle at the connection point, thereby restricting and fixing the position of the previous watch buckle. This prevents the push plate from contacting the previous watch buckle when pushing the watch buckle at the connection point, which would cause the position of the previous watch buckle to shift, resulting in the watch buckle being conveyed crookedly when pushing the watch buckle again, causing assembly problems. When the push plate and the slide plate reset, the reaction force of the support spring and the tension spring drives the guide block and the positioning block to reset, facilitating continued use.

[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0020] Appendix Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0021] See attached document Figures 1-5 A buckle assembly feeding mechanism includes a conveyor table 1, an extension plate 2 fixedly connected to the top of the conveyor table 1, a conveying mechanism, a pushing mechanism, a squeezing mechanism, a rotating mechanism, and a limiting mechanism. The conveying mechanism is located at the top of the conveyor table 1, the pushing mechanism is located at the top of the extension plate 2, the squeezing mechanism is located inside the extension plate 2, and the top and bottom of the squeezing mechanism are slidably connected through the top and bottom of the extension plate 2, respectively. The squeezing mechanism and the conveying mechanism are in intermittent contact. The limiting mechanism is slidably located inside the conveyor table 1, and the top of the limiting mechanism is connected through the inside of the conveyor table 1 and extends to the conveying mechanism. The rotating mechanism is located at the bottom of the extension plate 2, and one end of the rotating mechanism is in contact with the bottom of the squeezing mechanism, while the other end extends into the inside of the conveyor table 1 and is in contact with the bottom of the limiting mechanism.

[0022] In this implementation scheme, the conveying mechanism facilitates the transport of the watch buckle at the conveying head to the right side of the pushing mechanism. When the pushing mechanism starts, it first contacts the squeezing mechanism and applies pressure to the squeezing mechanism, causing the bottom of the squeezing mechanism to move downward. At the same time, it drives one end of the rotating mechanism to rotate downward while the other end rotates upward. This, in turn, drives the limiting mechanism to rise, facilitating the locking and fixing of the watch buckle at the conveying head to the position of the previous watch buckle. This prevents the subsequent pushing mechanism from contacting the previous watch buckle when pushing the watch buckle at the conveying head, which could cause the position of the previous watch buckle to shift, resulting in the watch buckle being transported crookedly and making it impossible to assemble.

[0023] Specifically, the conveying mechanism includes a conveyor belt 3, a connecting channel 4, a conveying channel 5, and a motor 6. The conveyor belt 3 is installed on the top of the conveyor platform 1, and one end of the conveyor belt 3 extends to the outside of the conveyor platform 1. A connecting channel 4 is provided on the top of the conveyor platform 1 near the end of the conveyor belt 3. A conveying channel 5 connected to the connecting channel 4 is provided on one side of the top of the conveyor platform 1. A motor 6 connected to the drive shaft of the conveyor belt 3 is installed on one side of the conveyor platform 1.

[0024] In this implementation scheme, the motor 6 is started, which drives the conveyor belt 3 to rotate, thereby conveying several buckles on the conveyor belt 3. The buckles on the conveyor belt 3 come into contact with each other, so the conveyor belt 3 pushes the buckles into the connecting channel 4. When the buckle at the conveying head moves from the connecting channel 4 to the connection between the connecting channel 4 and the conveying channel 5, it is convenient to carry out the subsequent buckle pushing work.

[0025] Specifically, the pushing mechanism includes a mounting plate 7, a cylinder 8, a slide groove 9, a sliding plate 10, and a push plate 11. The mounting plate 7 is fixedly connected to the top of the extension plate 2. The cylinder 8 is installed at the top of the mounting plate 7. A slide groove 9 is opened on one side of the mounting plate 7. The push plate 11 is fixedly connected to the output end of the cylinder 8. A sliding plate 10 is fixedly connected to one side of the push plate 11 near the inside of the slide groove 9.

[0026] In this embodiment, the cylinder 8 drives the push plate 11 to move, thereby the push plate 11 drives the slide plate 10 to move inside the slide groove 9. When the push plate 11 drives the slide plate 10 to contact the top of the extrusion mechanism, the length of the push plate 11 plus the length of the slide plate 10 can continuously apply pressure to the extrusion mechanism. When the push plate 11 contacts the buckle at the connection point, the buckle at the connection point is pushed into the conveying channel 5 and slides from the conveying channel 5 into the subsequent assembly equipment.

[0027] Specifically, the extrusion mechanism includes a guide plate 13, a guide block 14, a pressure rod 15, and a support spring 16. The top of the extension plate 2 has an installation hole 12 near the left side of the extrusion pusher. The guide plate 13 is slidably connected to the inside of the installation hole 12. The top of the guide plate 13 is fixedly connected to the guide block 14, which passes through the inside of the installation hole 12. The bottom of the guide plate 13 is fixedly connected to the pressure rod 15, which passes through the inside of the installation hole 12. The outside of the pressure rod 15 is fitted with a support spring 16. The bottom end of the support spring 16 is fixedly connected to the bottom of the inside of the installation hole 12, and the other end is fixedly connected to the bottom of the guide plate 13.

[0028] In this embodiment, when the push plate 11 drives the slide plate 10 to contact the guide block 14, the guide block 14 is squeezed and moves downward. Then, the guide block 14 drives the guide plate 13 to move inside the mounting hole 12. The guide plate 13 drives the support spring 16 to compress. Then, the guide plate 13 drives the pressure rod 15 to move downward, so that the bottom end of the pressure rod 15 can drive one end of the rotating mechanism to rotate downward.

[0029] Specifically, the limiting mechanism includes a movable plate 22, a positioning block 23, a support plate 24, a tension spring 25, a connecting rod 26, and a pressure plate 27. A movable groove 20 is provided on one side of the conveyor table 1 near the outer side of the rotating mechanism. A receiving groove 19 communicating with the movable groove 20 is provided inside the conveyor table 1. The top of the receiving groove 19 communicates with the surface of the conveying mechanism. Two limiting grooves 21 are provided inside the receiving groove 19, and the two limiting grooves 21 are symmetrically arranged. The two sides of the movable plate 22 are slidably connected to the inside of the two limiting grooves 21 respectively. A positioning block 23 passing through the top of the receiving groove 19 is fixedly connected to the top of the movable plate 22. Two support plates 24 are fixedly connected to the inner wall of the receiving groove 19, and the two support plates 24 are symmetrically arranged. A tension spring 25 is fixedly connected to the top of each support plate 24. The tops of the two tension springs 25 are fixedly connected to the bottom of the movable plate 22. A connecting rod 26 is fixedly connected to the bottom of the movable plate 22, and a pressure plate 27 is fixedly connected to the bottom of the connecting rod 26.

[0030] In this embodiment, when the pressure plate 27 moves upward, the pressure plate 27 drives the connecting rod 26 to move, the connecting rod 26 drives the moving plate 22 to move, and the moving plate 22 drives the tension spring 25 to stretch. Then the moving plate 22 drives the positioning block 23 to pass through the connecting channel 4 and lock into the inside of the previous buckle of the connecting buckle, thereby restricting and fixing the position of the previous buckle.

[0031] Specifically, the rotating mechanism includes a fixed plate 17 and a rotating plate 18. There are two fixed plates 17, and the top ends of the two fixed plates 17 are fixedly connected to the bottom end of the extension plate 2. The rotating plate 18 is connected between the two fixed plates 17 through a rotating shaft.

[0032] In this embodiment, when the bottom end of the pressure rod 15 contacts one end of the rotating plate 18, one end of the rotating plate 18 rotates downward and the other end rotates upward inside the movable groove 20. At this time, the other end of the rotating plate 18 contacts the pressure plate 27, which makes it convenient to lift the pressure plate 27 upward.

[0033] The working principle and usage process of this utility model are as follows: In use, the motor 6 is started, causing the conveyor belt 3 to rotate, thereby conveying several buckles on the conveyor belt 3. The buckles on the conveyor belt 3 contact each other, pushing them into the connecting channel 4. When the buckle at the conveyor head moves from the connecting channel 4 to the connection point between the connecting channel 4 and the conveying channel 5, the cylinder 8 is activated, causing the push plate 11 to move. The push plate 11 then moves the slide plate 10 within the slide groove 9. When the push plate 11 and the slide plate 10 contact the guide block 14, the guide block 14 is compressed and moves downwards. The guide block 14 then moves the guide plate 13 within the mounting hole 12, compressing the support spring 16. The guide plate 13 then moves the pressure rod 15 downwards, causing its bottom end to contact one end of the rotating plate 18. Thus, one end of the rotating plate 18 rotates downwards, while the other end rotates upwards within the movable groove 20. At this time, the other end of the rotating plate 18 contacts the pressure plate 27 and drives the pressure plate 27 to move upward. As a result, the pressure plate 27 drives the connecting rod 26 to move, the connecting rod 26 drives the moving plate 22 to move, and the moving plate 22 drives the tension spring 25 to stretch. Then, the moving plate 22 drives the positioning block 23 to pass through the connecting channel 4 and lock into the inside of the previous buckle of the connecting buckle, thereby restricting and fixing the position of the previous buckle. This prevents the push plate 11 from contacting the previous buckle when pushing the connecting buckle, which would cause the position of the previous buckle to shift. This would result in the buckle being transported crookedly when pushing the buckle again, causing assembly problems. When the push plate 11 contacts the connecting buckle, it pushes the connecting buckle into the conveying channel 5 and slides it into the subsequent assembly equipment. Then, when the push plate 11 and the slide plate 10 reset, the reaction force of the supporting spring 16 and the tension spring 25 drives the guide block 14 and the positioning block 23 to reset, making it convenient for continued use.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
