Description

Technical Field

[0001] The present application relates to the technical field of feeding equipment, and in particular to a combined feeding mechanism. Background Art

[0002] A wall switch is an electrical switch installed on the wall to connect and disconnect the circuit and control the lighting. During the production of a wall switch, multiple parts need to be assembled.

[0003] In order to improve the assembly efficiency of wall switches, fully automatic assembly machines are generally used to assemble wall switches. During the assembly process, the parts of the wall switches need to be fed through a feeding mechanism. The existing feeding mechanism is generally used alone, and cannot accurately guarantee the feeding time interval, feeding position and feeding angle, which is inconvenient for users. Utility Model Content

[0004] The utility model aims to solve or at least alleviate the problem that the existing feeding mechanism is generally used alone, cannot accurately guarantee the feeding time interval, feeding position and feeding angle, and is inconvenient for users to use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A combined feeding mechanism comprises a vibration material plate with a spiral track inside, a material guide plate connected to the spiral track is fixedly connected to the outer wall of the vibration material plate, a linear vibration material machine is fixedly installed on the lower surface of the material guide plate, and notches aligned with each other are arranged on the side walls of the end of the material guide plate away from the spiral track, two pushing structures with pushing directions perpendicular to each other are installed on both sides of the material guide plate, and a programmable controller for controlling the pushing structure to push materials is also fixedly connected to the outer wall of the vibration material plate.

[0007] By adopting the above technical solution, when using, the user first puts the parts into the vibration tray. After the vibration tray is started, the parts rise along the spiral track due to vertical vibration. During the rising process, they undergo a series of track screening and posture changes, so that the parts can automatically enter the inner cavity of the guide plate in a unified state according to the assembly requirements. The linear vibration machine installed on the bottom wall of the guide plate controls the vibration frequency of the motor through the inverter, thereby controlling the uniform movement of the wall switch parts on the guide plate until the parts are moved to the position where the notches are opened on the side walls of the guide plate. At this time, the programmable controller first controls one of the pushing structures to push the parts along the connecting direction of the two notches, and pushes the parts from the guide plate to the pallet through the notch, and then controls the other pushing structure to push the parts along the length direction of the guide plate, so as to accurately load the parts, thereby avoiding the problem that the existing loading mechanism is generally used alone, cannot accurately guarantee the loading time interval, loading position and loading angle, and is inconvenient for users to use.

[0008] Optionally, the vibration plate includes a hopper and a pulse electromagnet installed below the hopper to drive the hopper to vibrate in a vertical direction, and the spiral track is arranged in the inner cavity of the hopper.

[0009] By adopting the above technical solution, when in use, the parts in the hopper rise along the spiral track due to vertical vibration. During the rising process, they undergo a series of track screening and posture changes, so that the parts can automatically enter the inner cavity of the guide plate in a unified state according to assembly requirements.

[0010] Optionally, one end of the material guide plate away from the material vibration plate is bent upward to form a first blocking portion, and the distance between the first blocking portion and the side wall of the notch is equal to the width of the material conveyed by the feeding mechanism.

[0011] By adopting the above technical solution, a first blocking portion is provided to block parts from the end of the guide plate, thereby avoiding the problem of parts falling from the end of the guide plate due to vibration as much as possible.

[0012] Optionally, the bottom wall of the notch on one side extends outward to form a support plate, and the side of the support plate away from the material guide plate is bent upward to form a second blocking portion, and the distance between the second blocking portion and the outer wall of the material guide plate is equal to the length of the material transported by the feeding mechanism.

[0013] By adopting the above technical solution, a support plate is provided to support the parts pushed out through the notch from below, and a second blocking portion is provided to limit the parts pushed onto the support plate to prevent the parts from sliding off the support plate.

[0014] Optionally, the pushing structure includes two U-shaped brackets, and a cylinder is fixedly connected to the outer wall of the middle section of the two brackets. A piston rod is installed on the output end of the cylinder. The piston rod passes through the bracket and is slidably connected to the bracket, and a push plate is fixedly connected to the end of the piston rod away from the cylinder.

[0015] By adopting the above technical solution, when in use, the programmable controller controls the cylinder to start, pushes the piston rod to extend, and thus drives the push plate to move to push the material.

[0016] Optionally, both ends of the two brackets are fixedly connected to a mounting plate, and bolts are passed through the mounting plate, one of the brackets is screwed to the first blocking portion through the bolts, and the other bracket is screwed to the second blocking portion through the bolts.

[0017] By adopting the above technical solution, a mounting plate is provided to improve the stability of the bracket installation, and a screw connection method is adopted, which not only ensures a stable connection, but also facilitates the user to install and disassemble the bracket.

[0018] Optionally, the push plate is in a rectangular block structure, and a rubber pad is bonded to a side of the push plate away from the piston rod.

[0019] By adopting the above technical solution, rubber pads are set to protect parts, so as to avoid the problem of hard squeezing of the push plate and the parts during the pushing process, which may cause deformation and damage of the parts.

[0020] In summary, the beneficial effects of this application are as follows:

[0021] The present application achieves this by coordinating the structures such as a vibration tray, a guide plate, a linear vibration machine, a cylinder and a programmable controller. In the process of conveying the parts to the guide plate, the vibration tray can go through a series of track screening and posture changes, so that the parts can be in a unified state according to the assembly requirements. The linear vibration machine can be used to adjust the vibration frequency to make the parts move at a uniform speed. Finally, the programmable controller is used to control the cylinder to push the parts out within the set time interval for precise loading. This avoids the problem that the existing loading mechanism is generally used alone, cannot accurately guarantee the loading time interval, loading position and loading angle, and is inconvenient for users.

[0027] See also Figure 1-3 A combined feeding mechanism comprises a vibration material tray 1 with a spiral track 2 inside, and a guide plate 3 connected to the spiral track 2 is fixedly connected to the outer wall of the vibration material tray 1. When in use, the user can guide the wall switch parts to be loaded into the sub-vibration material tray 1, and the wall switch parts inside the vibration material tray 1 are transferred to the guide plate 3 in sequence through the vibration of the vibration material tray 1.

[0028] A linear material vibrator 4 is fixedly mounted on the lower surface of the material guide plate 3 . The linear material vibrator 4 controls the vibration frequency of the motor through a frequency converter, thereby controlling the uniform movement of the wall switch parts on the material guide plate 3 .

[0029] Mutually aligned notches 5 are provided on the side walls of the end of the guide plate 3 away from the spiral track 2, and two pushing structures with mutually perpendicular pushing directions are installed on both sides of the guide plate 3. A programmable controller 15 for controlling the pushing structure to push materials is also fixedly connected to the outer wall of the vibration plate 1.

[0030] When the wall switch part on the guide plate 3 moves to the notch 5, the programmable controller 15 first controls one of the pushing structures to push the part along the direction of the line connecting the two notches 5, and pushes the part out of the guide plate 3 through the notch 5, and then controls the other pushing structure to push the part along the length direction of the guide plate 3 to load the part.

[0031] Reference Figure 1 The vibration tray 1 includes a hopper and a pulse electromagnet installed below the hopper to drive the hopper to vibrate in the vertical direction. The spiral track 2 is set in the inner cavity of the hopper. When in use, the parts in the hopper rise along the spiral track 4 due to vertical vibration. During the rising process, they are screened and changed in posture by a series of tracks, so that the parts can automatically enter the inner cavity of the guide plate 3 in a unified state according to the assembly requirements.

[0032] Reference Figure 2The end of the guide plate 3 away from the vibration plate 1 is bent upward to form a first blocking portion 6. The distance between the first blocking portion 6 and the side wall of the notch 5 is equal to the width of the material conveyed by the feeding mechanism. The first blocking portion 6 is provided to block parts from the end of the guide plate 3 to avoid the problem of parts falling from the end of the guide plate 3 due to vibration.

[0033] Reference Figure 2 The bottom wall of the notch 5 on one side extends outward to form a support plate 7, and the side of the support plate 7 away from the guide plate 3 is bent upward to form a second blocking portion 8. The distance between the second blocking portion 8 and the outer wall of the guide plate 3 is equal to the length of the material conveyed by the feeding mechanism. The support plate 7 is provided to support the parts pushed out through the notch 5 from below, and the second blocking portion 8 is provided to limit the parts pushed onto the support plate 7 to prevent the parts from sliding off the support plate 7.

[0034] Reference Figure 3 The material pushing structure includes two U-shaped brackets 9, and the outer walls of the middle sections of the two brackets 9 are fixedly connected with a cylinder 12. The output end of the cylinder 12 is installed with a piston rod 13, which penetrates the bracket 9 and is slidably connected to the bracket 9. The end of the piston rod 13 away from the cylinder 12 is fixedly connected with a push plate 14. When in use, the programmable controller 15 controls the cylinder 12 to start, pushes the piston rod 13 to extend, and thus drives the push plate 14 to move to push the material.

[0035] Reference Figure 3 Both ends of the two brackets 9 are fixedly connected with mounting plates 10, and bolts 11 are passed through the mounting plates 10. One of the brackets 9 is screwed to the first blocking portion 6 through the bolts 11, and the other bracket 9 is screwed to the second blocking portion 8 through the bolts 11. The mounting plates 10 are provided to improve the stability of the mounting of the brackets 9. The screw connection method is adopted, which is not only stable, but also convenient for users to install and disassemble the brackets 9.

[0036] Reference Figure 3 The push plate 14 is a rectangular block structure, and a rubber pad is bonded to the side of the push plate 14 away from the piston rod 13. The rubber pad is provided to protect the parts and to avoid the problem of hard extrusion between the push plate 14 and the parts during the pushing process, which may cause deformation and damage of the parts.

[0037] The implementation principle of the present application is as follows: when in use, the user first puts the parts into the vibration tray 1. When the vibration tray 1 is started, the parts rise along the spiral track 2 due to vertical vibration. During the rising process, they undergo a series of track screening and posture changes, so that the parts can automatically enter the inner cavity of the guide plate 3 in a unified state according to the assembly requirements. The linear vibration machine 4 is installed on the bottom wall of the guide plate 3. The linear vibration machine 4 controls the vibration frequency of the motor through the frequency converter, thereby controlling the uniform movement of the wall switch parts on the guide plate 3 until the parts are moved to the position where the notches 5 are opened on the side walls of the guide plate 3. At this time, the programmable controller 15 first controls one of the pushing structures to push the parts along the connecting direction of the two notches 5, and pushes the parts from the guide plate 3 to the support plate 7 through the notch 5, and then controls the other pushing structure to push the parts along the length direction of the guide plate 3, so as to accurately load the parts, thereby avoiding the problem that the existing loading mechanism is generally used alone, cannot accurately guarantee the loading time interval, loading position and loading angle, and is inconvenient for users to use.
