Description

Technical Field

[0001] This application relates to the field of electronic component manufacturing equipment technology, and in particular to a feeding and positioning device for a shielding ring. Background Technology

[0002] like Figure 1 The shielding ring shown includes an interconnected annular portion 100 and cylindrical portion 110, resulting in a T-shaped longitudinal cross-section. A mounting hole is formed through the cylindrical portion of the shielding ring. As a core auxiliary component for electromagnetic interference shielding, the shielding ring typically needs to be assembled with electronic components. These electronic components are inserted into the mounting hole, thus placing stringent requirements on the continuity of the shielding ring's material supply and the high precision and consistency of its positioning.

[0003] Currently, the technological upgrades in material feeding and positioning during the shielding ring processing stage are lagging behind. Most small and medium-sized production lines still rely on the traditional method of manual feeding combined with manual positioning. This method not only makes it difficult to ensure the continuity of material feeding, leading to production line interruptions, but also makes the positioning accuracy of manual operation susceptible to human factors, resulting in poor consistency. This directly restricts the processing quality and production efficiency of subsequent processes and cannot meet the precision manufacturing requirements of modern production lines. Therefore, it needs to be improved. Utility Model Content

[0004] To facilitate the feeding and positioning of shielding rings and improve production efficiency, this application provides a device for feeding and positioning shielding rings.

[0005] The shielding ring feeding and positioning device provided in this application adopts the following technical solution: A device for feeding and positioning shielding rings includes a vibratory feeder, a conveying track, a base, a positioning seat, a clamping member, and a position sensor. The vibratory feeder is used to vibrate and feed the shielding rings. The conveying track is connected to the output end of the vibratory feeder and has a conveying groove for conveying the shielding rings. The base is located on one side of the vibratory feeder. The positioning seat is located on the base and on the side of the conveying track away from the vibratory feeder. The positioning seat has a positioning groove communicating with the conveying groove for accommodating a single shielding ring. The clamping member is located on the positioning seat for clamping the shielding ring in the positioning groove. The position sensor is located on the positioning seat for detecting whether the shielding ring is in position.

[0006] By adopting the above technical solution, the shielding rings are arranged in an orderly manner under the vibration of the vibratory feeder, and then conveyed in rows along the conveying groove of the conveying track and approach the positioning seat until a single shielding ring falls into the positioning groove. At this time, the position sensor detects that the shielding ring in the positioning groove has moved to the preset position, and outputs a position detection signal to the drive control unit of the vibratory feeder through the signal transmission link, thereby triggering the vibratory feeder to stop vibrating and feeding, avoiding continuous vibration interference from the vibratory feeder when the shielding rings are pressed together.

[0007] Then, the clamping device clamps the shielding ring in the positioning groove to achieve positioning, reduce the adverse effects of the shielding ring assembly position deviation on subsequent processes, and improve the processing quality. Finally, the workers use tools to insert the corresponding electronic components onto the shielding ring. After the assembly is completed, the pressure of the clamping device is released, and the workers remove the finished product. This process is repeated to achieve continuous production.

[0008] The position sensor is a contact-type position sensor (such as a mechanical contact limit switch or a contact proximity switch). After making mechanical contact with the workpiece and reaching a preset trigger threshold, it converts the mechanical contact signal into an electrical signal (usually a switching signal, such as an on / off signal or a high / low level signal). The position signal output by the sensor is transmitted to the drive controller of the vibratory feeder (such as a relay, PLC, or dedicated drive circuit board) via wired transmission (such as a wire connection) or a wireless transmission module. The position sensor is also an existing device and can be selected appropriately according to actual needs.

[0009] Preferably, the clamping component is a gripper cylinder, and the positioning seat has a clearance hole for the gripper of the gripper cylinder to pass through and move. Both grippers of the gripper cylinder are detachably connected to clamping plates, and the two clamping plates are used to clamp the shielding ring.

[0010] By adopting the above technical solution, the two grippers of the gripper cylinder can drive the two clamping plates to move closer to each other, thereby clamping the cylindrical part of the shielding ring.

[0011] Preferably, the clamping plate is fastened to the gripper by fasteners, the fasteners being fastening bolts or fastening screws, and the clamping plate has an arc-shaped groove that fits against the cylindrical surface of the shielding ring.

[0012] By adopting the above technical solution, the arc-shaped groove can fit the outer surface shape of the cylindrical part, which facilitates increasing the contact area between the clamping plate and the cylindrical part and improving the stability of the shielding ring after clamping. Fasteners pass through the clamping plate and are threaded onto the jaws, enabling the clamping plate to be detachable and easily replaced, thus improving practicality. During the production process, the clamping plate can be replaced to accommodate shielding rings of different specifications, simplifying the specification switching process and reducing adaptation costs.

[0013] Preferably, the conveying track includes a track body and a fixed seat. The two ends of the track body are respectively connected to the vibrating plate and the fixed seat. The fixed seat is located between the track body and the positioning seat. The fixed seat is provided with an inclined guide surface, which is inclined along the conveying direction of the shielding ring.

[0014] By adopting the above technical solution, the shielding rings gradually approach the positioning seat along the conveying groove. By setting an inclined guide surface near the positioning seat, the inclined guide surface can prevent the shielding rings from getting stuck in the conveying groove and improve the smoothness of material conveying.

[0015] Preferably, it further includes a support bar, a fixed shaft, and a guide wheel. The support bar is disposed on the positioning seat and is arranged along the moving direction of the gripper. The fixed shaft is disposed on the support bar. The guide wheel is rotatably connected to the fixed shaft and is tangent to the clamping plate.

[0016] By adopting the above technical solution, when the two clamping plates approach each other, one side of the clamping plate can move linearly along the guide wheel. Rolling friction occurs between the guide wheel and the clamping plate, reducing static friction. The presence of the guide wheel restricts the lateral position of the clamping plates, improving their stability during movement.

[0017] Preferably, it further includes a guide post and a return spring. The positioning seat has a guide hole, and the return spring is horizontally disposed in the guide hole. The two ends of the return spring are respectively connected to the positioning seat and the guide post. The guide post is parallel to the elastic force direction of the return spring. The support bar is disposed on the end of the guide post away from the return spring, and the support bar and the guide post are perpendicular to each other.

[0018] By adopting the above technical solution, during the movement of the clamping plate, the guide wheel will inevitably be subjected to the force of the clamping plate, meaning the guide wheel has a tendency to move away from the clamping plate. The guide wheel can transfer the force to the support bar and guide post, causing the return spring to be compressed and generate elastic potential energy. This elastic force reacts on the guide post, thus preventing the guide wheel from moving away from the clamping plate. The presence of the return spring ensures that the contact between the clamping plate and the guide wheel is elastic rather than rigid, facilitating the removal and installation of the clamping plate from the gripper cylinder.

[0019] Preferably, it also includes an electric push rod and a pressure block. The electric push rod is disposed on the base, and the pressure block is connected to the electric push rod and located directly above the positioning groove for pressing the shielding ring and other electronic components together.

[0020] By adopting the above technical solution, after the staff places the electronic components into the shielding ring in the positioning groove, the electric push rod can be used to control the pressure block to move vertically downward, thereby realizing the pressing assembly.

[0021] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up a vibratory feeder, conveying track, base, positioning seat, clamping parts and position sensor, the vibratory feeder vibrates to feed the shielding ring, and the clamping parts clamp the individual shielding rings to fix the shielding rings, reduce the adverse effects of the shielding ring assembly position deviation on subsequent processes, and improve the processing quality of the process.

[0022] (2) By setting the clamp plate to be detachably connected to the clamp cylinder, it is convenient to replace the clamp plate to adapt to different specifications of shielding rings, thus improving practicality.

[0023] (3) By setting guide wheels, the guide wheels can restrict the lateral position of the clamping plate without interfering with the normal movement of the clamping plate. Attached Figure Description

For example, they can refer to a fixed connection; a detachable connection; an integral part; or a mechanical connection.

[0029] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0030] This application discloses a feeding and positioning device for a shielding ring. (Refer to...) Figure 2 and Figure 3 The feeding and positioning device includes a vibratory feeder 1, a conveying track 2, a base 3, a positioning seat 4, a clamping element 5, and a position sensor 6. The vibratory feeder 1 is used to vibrate and feed the shielding rings. The vibratory feeder 1 is an existing device and can be directly applied to this application. The conveying track 2 is horizontally arranged and fixedly connected to the output end of the vibratory feeder 1. The conveying track 2 has a conveying groove 7 for horizontally conveying the shielding rings.

[0031] The base 3 is located on one side of the vibratory feeder 1. The positioning seat 4 is fixedly installed on the base 3 and located on the side of the conveying track 2 away from the vibratory feeder 1. The positioning seat 4 has a positioning groove 8 that communicates with the conveying groove 7. The positioning groove 8 is used to accommodate a single shielding ring. The clamping member 5 is installed on the positioning seat 4 and is used to clamp the shielding ring in the positioning groove 8. The position sensor 6 is installed on the positioning seat 4 and is close to the positioning groove 8. The position sensor 6 is used to detect whether the shielding ring is in position.

[0032] The shielding rings are arranged in an orderly manner by the vibration of the vibratory feeder 1, and then conveyed in rows along the conveying groove 7 of the conveying track 2 and approach the positioning seat 4 until a single shielding ring falls into the positioning groove 8. At this time, the position sensor 6 detects that the shielding ring in the positioning groove 8 has moved to the preset position, and outputs a position detection signal to the drive control unit of the vibratory feeder 1 through the signal transmission link, thereby triggering the vibratory feeder 1 to stop the vibration feeding action, so as to avoid the vibratory feeder 1 from continuously generating vibration interference when the shielding ring is pressed together.

[0033] Then, clamping component 5 clamps the shielding ring in the positioning groove 8 to achieve positioning, reducing the adverse effects of shielding ring assembly position deviation on subsequent processes and improving process quality. Finally, the operator uses tools to insert the corresponding electronic components onto the shielding ring, and after assembly, releases the pressure of clamping component 5, and the operator removes the finished product. This cycle is repeated to achieve continuous production. Specifically, the clamping component 5 is a gripper cylinder, and the positioning seat 4 has a clearance hole for the gripper of the gripper cylinder to pass through and move. Both grippers of the gripper cylinder are detachably connected to clamping plates 9, which are used to clamp the shielding ring. The clamping plates 9 are locked to the grippers by fasteners, such as bolts or screws. The clamping plates 9 also have arc-shaped grooves 10 that fit against the cylindrical surface of the shielding ring, increasing the contact area between the clamping plates 9 and the cylindrical part, thus improving the stability of the shielding ring after clamping. During production, the clamping plates 9 can be replaced to accommodate shielding rings of different specifications, reducing adaptation costs.

[0034] In this embodiment, the conveying track 2 includes a track body 21 and a fixed seat 22. The two ends of the track body 21 are connected to the vibrating plate 1 and the fixed seat 22, respectively. The fixed seat 22 is located between the track body 21 and the positioning seat 4. An inclined guide surface 11 is provided on the fixed seat 22. The inclined guide surface 11 is located within the conveying groove 7 and is inclined along the conveying direction of the shielding rings. The inclined guide surface 11 can prevent the shielding rings from getting stuck in the conveying groove 7, improving the smoothness of material conveying to the positioning groove 8.

[0035] Combination Figure 4 In some embodiments, a support bar 12 is also installed on the positioning seat 4, and the support bar 12 is arranged along the moving direction of the gripper. A fixed shaft 13 is fixedly connected to the support bar 12, and a guide wheel 14 is rotatably connected to the fixed shaft 13. The guide wheel 14 uses the fixed shaft 13 as its pivot, and one side of the clamping plate 9 is tangent to the guide wheel 14. When the two clamping plates 9 approach each other, one side of the clamping plate 9 can move linearly along the guide wheel 14. Rolling friction occurs between the guide wheel 14 and the clamping plate 9, reducing static friction. The presence of the guide wheel 14 restricts the lateral position of the clamping plate 9, improving the stability of the clamping plate 9 during movement. The positioning seat 4 also has a guide hole 15, in which a return spring 16 and a guide post 17 are installed. The two ends of the return spring 16 are connected to the guide seat and the guide post 17, respectively. Both the return spring 16 and the guide post 17 are horizontally positioned, so that the guide post 17 is parallel to the direction of the spring force of the return spring 16. A portion of the guide post 17 is located inside the guide hole 15, and another portion is located outside the guide hole 15. A support bar 12 is installed on the end of the guide post 17 furthest from the return spring 16, and the support bar 12 and the guide post 17 are perpendicular to each other.

[0036] During the movement of the clamping plate 9, the guide wheel 14 inevitably experiences a force from the clamping plate 9, meaning the guide wheel 14 tends to move away from the clamping plate 9. The guide wheel 14 can transmit this force to the support bar 12 and the guide post 17, causing the return spring 16 to be compressed and generate elastic potential energy. This elastic force reacts on the guide post 17, thus preventing the guide wheel 14 from moving away from the clamping plate 9. The presence of the return spring 16 ensures that the clamping plate 9 and the guide wheel 14 have elastic contact rather than rigid contact, facilitating the removal and installation of the clamping plate 9 from the gripper cylinder.

[0037] Reference Figure 5 In addition, in some embodiments, an electric push rod 18 is also installed on the base 3. A pressure block 19 is connected to the piston rod of the electric push rod 18. The pressure block 19 is located directly above the positioning groove 8 and is used to press the shielding ring and the pad components together. The electric push rod 18 is used to drive the pressure block 19 to move up and down. After the operator places the electronic components into the shielding ring in the positioning groove 8, the electric push rod 18 can be run to control the pressure block 19 to move vertically downward, thereby realizing the pressing assembly.

[0038] The implementation principle of the shielding ring feeding and positioning device in this application embodiment is as follows: After the shielding rings are arranged in an orderly manner by the vibration of the vibrating plate 1, they are transported in rows along the conveying groove 7 of the conveying track 2 and gradually approach the positioning seat 4, and finally a single shielding ring falls into the positioning groove 8. When the position sensor 6 detects that the shielding ring in the positioning groove 8 has reached the preset position, it sends a position detection signal to the drive control unit of the vibrating plate 1 through the signal transmission link, thereby triggering the vibrating plate 1 to stop the vibration feeding action, so as to avoid the vibrating plate 1 continuously generating vibration interference during the shielding ring pressing process.

[0039] Subsequently, clamping component 5 is activated to clamp and position the shielding ring within the positioning groove 8, effectively reducing the adverse effects of shielding ring assembly position deviations on subsequent processes and improving process quality. Finally, the electric push rod 18 drives the pressure block 19 to move vertically downwards, completing the pressing assembly operation. After assembly, clamping component 5 releases pressure on the shielding ring, and the worker removes the finished product. This process is repeated continuously to achieve continuous production.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
