Description

Technical Field

[0001] The present invention belongs to the technical field of vibration plate equipment, and in particular relates to an automatic feeding device for a vibration plate and a control method thereof. Background Art

[0002] The vibration plate is an auxiliary equipment of automatic assembly machinery, which can discharge various products in an orderly manner. It can cooperate with automatic assembly equipment to assemble various parts of the product into a complete product, or cooperate with automatic processing machinery to complete the processing of workpieces. There is a pulse electromagnet under the vibration plate hopper, which can make the hopper vibrate in the vertical direction. The inclined spring sheet drives the hopper to perform torsional vibration around its vertical axis. The parts in the hopper rise along the spiral track due to this vibration. During the rising process, they pass through a series of track screening or posture changes. The parts can automatically enter the assembly or processing position in a unified state according to the requirements of assembly or processing. Its working purpose is to automatically and orderly arrange the disordered workpieces in a directional and accurate manner through vibration and transport them to the next process.

[0003] When using a traditional vibrating plate, most people add materials to the inside of the vibrating plate manually. However, manual loading requires workers to always stay next to the vibrating plate and add materials to the inside of the vibrating plate at regular intervals, which wastes human resources, increases labor costs to a certain extent, and is not convenient to use. Summary of the Invention

[0004] The present invention provides an automatic feeding device for a vibration plate and a control method thereof, which are used to solve the technical problem that the existing vibration plate needs to add materials autonomously and regularly when feeding.

[0005] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: A vibration disk automatic loading device includes a base, a vibration disk, a turntable, a support rod, a discharge box and a driving member. The vibration disk is mounted on the base. One side of the turntable is rotatably mounted on the base, and an eccentric wheel is mounted on the other side of the turntable. The support rod is mounted on the base. The opposite sides of the discharge box are rotatably mounted on the two support rods respectively, the discharge box is located above the vibration disk, the discharge box has an opening on the side close to the vibration disk, the support rod is located on the side of the discharge box close to the opening, and the eccentric wheel abuts against the bottom of the discharge box away from the opening. The driving member is mounted on the base, and one end of the driving member is transmission-connected to the turntable so that the turntable rotates intermittently to drive the eccentric wheel to rotate, thereby causing the discharge box to rotate along the first direction relative to the support rod.

[0006] When in use, the vibration plate automatic feeding device provided by the present invention first places the material in the discharge box, and the driving member drives the turntable to rotate intermittently, and drives the eccentric wheel to rotate, so that the discharge box rotates in a first direction relative to the support rod. After a part of the material enters the vibration plate, the driving member continues to drive the turntable to rotate, and drives the eccentric wheel to rotate, so that the discharge box rotates in the opposite direction of the first direction under the action of gravity, and then stops feeding.

[0007] Optionally, the driving member includes a disc, a fixed rod, and a transmission rod. The disc is rotatably mounted on the base, and a transmission shaft is mounted on the side of the disc away from the base, and the transmission shaft is located at the edge of the disc. The fixed rod is mounted on the base. The transmission rod is sleeved on the fixed rod and rotates relative to the fixed rod. One side of the transmission rod has a slide groove, and the transmission shaft is slidably mounted in the slide groove. Two abutment blocks are mounted on the other end of the transmission rod, and a plurality of protrusions are spaced apart on the circumferential outer side of the turntable. The disc rotates to make the transmission rod swing along the second direction and the third direction, so that the two abutment blocks abut against the protrusions and drive the turntable to rotate.

[0008] Optionally, the protrusion is cylindrical, and there is an angle between the two abutment blocks, and they are spaced apart on the end of the transmission rod away from the slide groove, so that when the transmission rod moves along the second direction and the third direction, the two abutment blocks abut against the protrusion and drive the turntable to rotate.

[0009] Optionally, the driving member further comprises a driving motor which is mounted on the base, and an output shaft of the driving motor is connected to a side of the disc away from the transmission shaft.

[0010] Optionally, the vibrating plate automatic feeding device further comprises a mounting plate, wherein the mounting plate is mounted on the base, and the rotating plate is rotatably mounted on the mounting plate at a side away from the eccentric wheel.

[0011] Optionally, the vibrating plate automatic feeding device further comprises a connecting rod, one end of which is connected to a side of the rotating plate away from the mounting plate, and the other end of which is connected to the eccentric wheel.

[0012] Optionally, the automatic feeding device for a vibrating plate further comprises a material guide frame, which is installed at the opening and is used to guide the material in the discharge box into the vibrating plate.

[0013] A control method for automatic feeding of a vibrating plate comprises the following steps:

[0014] Step 1: Place the material in the discharge box.

[0015] Step 2: The driving motor drives the disc to rotate, so that the transmission rod swings relative to the fixed rod along the second direction and the third direction, thereby causing the two abutment blocks to abut against the protrusions and causing the turntable to rotate intermittently.

[0016] Step three: the turntable rotates to drive the connecting rod to rotate, and the eccentric wheel rotates, so that the discharge box deflects along the first direction relative to the support rod, and then the material is transported into the vibrating plate.

[0017] Step 4: According to the speed at which the vibration plate arranges the materials, the rotation speed of the output shaft of the driving motor is adjusted to achieve automatic loading of the vibration plate.

[0018] It can be seen from the above technical solution that the beneficial effect of the automatic feeding device of a vibration plate provided by the present invention is that: by setting a driving member and an eccentric wheel, the driving member drives the turntable to rotate intermittently, thereby causing the eccentric wheel to rotate to introduce the material in the discharge box into the vibration plate, solving the technical problem that the existing vibration plate needs to manually and autonomously add materials at a regular time when loading.

[0031] Example

[0032] When using a traditional vibrating plate, most people add materials to the inside of the vibrating plate manually. However, manual loading requires workers to always stay next to the vibrating plate and add materials to the inside of the vibrating plate at regular intervals, which wastes human resources, increases labor costs to a certain extent, and is not convenient to use.

[0033] In order to solve the above technical problems, refer to Figure 1 and3 As shown, this embodiment provides a vibration plate automatic loading device which may include a base 1, a vibration plate 2, a turntable 3, a support rod 5, a discharge box 6 and a driving member 7. The vibration plate 2 is mounted on the base 1. One side of the turntable 3 is rotatably mounted on the base 1, and an eccentric wheel 4 is mounted on the other side of the turntable 3. The support rod 5 is mounted on the base 1. The opposite sides of the discharge box 6 are rotatably mounted on the two support rods 5 respectively. The discharge box 6 is located above the vibration plate 2. The discharge box 6 has an opening on the side close to the vibration plate 2. The support rod 5 is located on the side of the discharge box 6 close to the opening, and the eccentric wheel 4 abuts against the bottom of the discharge box 6 away from the opening. The driving member 7 is mounted on the base 1, and one end of the driving member 7 is transmission-connected to the turntable 3 so that the turntable 3 rotates intermittently to drive the eccentric wheel 4 to rotate, thereby causing the discharge box 6 to rotate along the first direction relative to the support rod 5. Figure 3 The direction indicated by arrow A is the first direction. A cover plate may be provided on the top of the discharge box 6, and the cover plate and the top of the discharge box 6 may be connected by a snap fastener. This prevents the material in the discharge box 6 from falling out of the top of the discharge box 6 when the discharge box 6 rotates relative to the support rod 5 in the first direction.

[0034] Through the above structure, this embodiment provides an automatic feeding device for a vibration plate. When in use, the material is first placed in the discharge box 6, and the drive member 7 drives the turntable 3 to rotate intermittently, and drives the eccentric wheel 4 to rotate, so that the discharge box 6 rotates in the first direction relative to the support rod 5. After a part of the material enters the vibration plate 2, the drive member 7 continues to drive the turntable 3 to rotate, and drives the eccentric wheel 4 to rotate, so that the discharge box 6 rotates in the opposite direction of the first direction under the action of gravity, and then stops feeding.

[0035] On the basis of the above, in order to facilitate the installation of the driving member 7, refer to Figure 5 and Figure 6 As shown, the driving member 7 may include a disc 8, a fixed rod 9, and a transmission rod 10. The disc 8 is rotatably mounted on the base 1, and a transmission shaft 801 is mounted on the side of the disc 8 away from the base 1, and the transmission shaft 801 is located at the edge of the disc 8. The fixed rod 9 is mounted on the base 1. The transmission rod 10 is sleeved on the fixed rod 9 and rotates relative to the fixed rod 9. One side of the transmission rod 10 has a slide groove, and the transmission shaft 801 is slidably mounted in the slide groove. Two abutment blocks 11 are mounted on the other end of the transmission rod 10, and a plurality of protrusions 12 are spaced apart on the circumferential outer side of the turntable 3. The disc 8 rotates to make the transmission rod 10 swing along the second direction and the third direction, so that the two abutment blocks 11 abut against the protrusions 12, and drive the turntable 3 to rotate intermittently, thereby rotating the eccentric wheel 4, and causing the discharge box 6 to rotate along Figure 3 Rotate in the direction indicated by arrow A. Figure 5 and Figure 6 The direction indicated by the arrow B is the second direction. Figure 5 and Figure 6 The direction indicated by the arrow C is the third direction.

[0036] On the basis of the above, in order to facilitate the transmission rod 10 to drive the turntable 3 to rotate, refer to Figure 2 and Figure 6 As shown, the protrusion 12 can be cylindrical, with an angle between the two abutting blocks 11, and spaced apart on the end of the transmission rod 10 away from the slide slot, so that when the transmission rod 10 moves in the second direction and the third direction, the two abutting blocks 11 abut against the protrusion 12, and drive the turntable 3 to rotate. When the transmission rod 10 rotates in the third direction, the abutting block 11 away from the disc 8 abuts against the protrusion 12, and causes the protrusion 12 to rotate along the circumference of the turntable 3. When the transmission rod 10 rotates in the second direction, the other abutting block 11 close to the disc 8 abuts against the protrusion 12, and continues to drive the protrusion 12 to rotate along the circumference of the turntable 3. This reciprocating movement drives the turntable 3 to rotate. The speed of rotation of the turntable 3 can be controlled by the reciprocating swing speed of the transmission rod 10.

[0037] On the basis of the above, in order to facilitate the rotation of the disc 8, refer to Figure 5 As shown, the driving member 7 may further include a driving motor 13. The driving motor 13 is mounted on the base 1, and the output shaft of the driving motor 13 is connected to the side of the disk 8 that is away from the transmission shaft 801. The output shaft of the driving motor 13 rotates to drive the disk 8 to rotate, thereby causing the transmission rod 10 to perform an oscillatory motion in the second and third directions.

[0038] On the basis of the above, in order to facilitate the installation of the turntable 3, refer to Figure 2 and Figure 3 As shown, an automatic vibrating plate feeding device may further include a mounting plate 14. The mounting plate 14 is mounted on the base 1, and the turntable 3 is rotatably mounted on the mounting plate 14 on the side away from the eccentric wheel 4. The mounting plate 14 is arranged on the side of the base 1 away from the opening of the discharge box 6, and the support rod 5 is located between the mounting plate 14 and the vibrating plate 2.

[0039] On the basis of the above, in order to facilitate the driving of the eccentric wheel 4, refer to Figure 5 As shown, an automatic vibrating plate feeding device may further include a connecting rod 15. One end of the connecting rod 15 is connected to the side of the turntable 3 away from the mounting plate 14, and the other end is connected to the eccentric wheel 4. The rotation of the turntable 3 drives the connecting rod 15 to rotate, thereby rotating the eccentric wheel 4.

[0040] On the basis of the above, in order to facilitate the pouring of materials into the vibration plate 2, refer to Figure 1 As shown, an automatic feeding device for a vibrating plate may further include a material guide frame 16. The material guide frame 16 is installed at the opening and is used to guide the material in the discharge box 6 into the vibrating plate 2. The material guide frame 16 may have a guide surface to prevent the material from falling outside the vibrating plate 2 when passing through the material guide frame 16.

[0041] In summary, in the use of a vibrating plate automatic feeding device, first, the material is placed in the discharge box 6, and the driving motor 13 drives the disc 8 to rotate, so that the transmission rod 10 swings along the second direction and the third direction relative to the fixed rod 9. When the transmission rod 10 rotates along the third direction, the abutment block 11 away from the disc 8 abuts against the protrusion 12, and causes the protrusion 12 to rotate along the circumference of the turntable 3. When the transmission rod 10 rotates along the second direction, the other abutment block 11 close to the disc 8 abuts against the protrusion 12, and continues to drive the protrusion 12 to rotate along the circumference of the turntable 3, and so on and so forth, so as to drive the turntable 3 to rotate, and the speed of the material arranged by the vibrating plate 2 is adjusted by adjusting the speed of the output shaft of the driving motor 13 to adjust the reciprocating swinging speed of the transmission rod 10, thereby controlling the rotation speed of the turntable 3, so that the turntable 3 rotates intermittently. The rotation of the turntable 3 drives the connecting rod 15 to rotate, and the eccentric wheel 4 rotates, thereby causing the discharge box 6 to deflect in the first direction relative to the support rod 5, and then the material is transported to the vibrating plate 2 through the material guide frame 16, thereby realizing automatic loading of the vibrating plate 2. This solves the technical problem of the existing vibrating plate that requires manual and regular addition of materials when loading.

[0042] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
