Description

Technical Field

[0001] This utility model relates to the field of piezoelectric vibrator feeding technology, and in particular to a feeding mechanism. Background Technology

[0002] A feeding mechanism is a device that uses vibration to transport workpieces. During operation, the high-frequency vibration generated by a vibrator causes the workpiece to jump forward along the feeding track, achieving continuous and directional transport. It is widely used in automated production lines and is suitable for transporting various workpieces such as parts and electronic components.

[0003] However, when the feeding mechanism is conveying workpieces, the workpieces usually enter the feeding track in a random direction, and the inlet of the existing direct vibration feeding track is usually a simple open structure or only a limit block structure, lacking a workpiece dispersion or guiding device, which causes the workpieces to pile up at the inlet of the feeding track, causing jamming. Utility Model Content

[0004] Therefore, it is necessary to provide a feeding mechanism that effectively solves the technical problem of the inability to transport workpieces in an orderly manner, and achieves efficient and orderly transport of workpieces.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A feeding mechanism includes: a feeding driver and a aligning block. The output end of the feeding driver is drivenly connected to a feeding track. A limiting block and a first blowing component are disposed opposite each other on the feeding end of the feeding track. A first feeding channel is formed between the first blowing component and the limiting block. The first blowing component is used to blow air toward the outer surface of the feeding track. The aligning block is disposed at the feeding end of the feeding track and is located behind the first blowing component. An aligning face is provided on the side of the aligning block facing the first blowing component.

[0007] Preferably, the first blowing assembly includes: a first air plate and a first air blowing driver, the first air plate is disposed at the feeding end of the feeding track, and the first air plate and the limiting block are spaced apart to form the first feeding channel; the first air plate has a first air hole, and the first air blowing driver is connected to the first air hole through a first air pipe.

[0008] Preferably, the feeding mechanism further includes: at least one slide rod, the feeding track is connected to the limiting block through the slide rod, and the limiting block is slidably disposed on the slide rod.

[0009] Preferably, a track pressing block and a track stop are provided in the middle of the feeding track, and the track pressing block and the track stop are spaced apart to form a second feeding channel.

[0010] Preferably, the feeding mechanism further includes: a material picking component, which is disposed at the discharge end of the feeding track. The material picking component includes: a first suction driver and a material picking element. The material picking element has a suction chamber inside. The outer surface of the material picking element near the discharge end of the feeding track has a plurality of first suction holes communicating with the suction chamber. The first suction driver is connected to the suction chamber through a first suction pipe.

[0011] Preferably, the feeding mechanism further includes a rotary driver and a slide, wherein a pusher is sleeved on the output end of the rotary driver, the pusher abuts against the suction member, and the suction member is slidably disposed on the slide.

[0012] Preferably, the feeding mechanism further includes a base, wherein the feeding driver, the rotary driver and the slide are all disposed on the base, and the feeding track is located above the feeding driver.

[0013] Preferably, the discharge end of the feeding track is provided with a first detection element, and the detection end of the first detection element extends into the middle of the feeding track.

[0014] Preferably, the feeding mechanism further includes a material positioning component, which includes a second suction driver and a material positioning block. The material positioning block is disposed at the discharge end of the feeding track, and a second suction hole is provided on the material positioning block. The second suction driver is connected to the side wall of the second suction hole through a second suction pipe.

[0015] Preferably, the feeding mechanism further includes: a second blowing assembly and a throwing pipe. The second blowing assembly includes: a second air plate and a second air blower. The second air plate is disposed at the discharge end of the feeding track and is located behind the material fixing assembly. The second air plate has a second air hole. The second air blower is connected to the second air hole through a second air pipe. The throwing pipe is disposed at the discharge end of the feeding track and is disposed opposite to the second air plate. The inlet end of the throwing pipe is aligned with the second air hole.

[0016] The beneficial effects of this invention are as follows: After the workpiece is conveyed onto the feeding track, the feeding driver drives the feeding track to vibrate, causing the workpiece to begin moving towards the first air blowing assembly and the straightening block. Misaligned workpieces are restricted by the limiting block and the first air blowing assembly, preventing them from entering between them. Then, the first air blowing assembly blows air onto the workpieces that have entered between the limiting block and the first air blowing assembly. Accompanied by the vibration of the feeding track, stacked or too close workpieces will separate. The workpieces are then vibrated until they come into contact with the straightening block, thus straightening the workpiece and allowing it to move on the feeding track in the correct posture. This design effectively solves the problem of workpiece stacking and greatly improves the practicality of the equipment. Attached Figure Description

[0026] Example 1

[0027] like Figures 1 to 3As shown, a feeding mechanism includes: a base 10, a feeding track 20, a first blowing assembly 30, a limiting block 40, and a leveling block 32. A feeding driver 11 is provided on the base 10, wherein the feeding driver 11 is a linear vibrator. The feeding track 20 is located above the feeding driver 11. A transmission shaft with vibration function is provided on the output end of the linear vibrator. A flange is provided at the end of the transmission shaft. A base is welded to the bottom end of the feeding track. A buffer washer is provided between the base and the flange. The base is rigidly connected to the flange through a stainless steel connecting rod, so that the feeding track is connected to the output end of the driver. Alternatively, a threaded hole can be opened at the end of the transmission shaft, and a through hole can be opened in the middle of the base. A limiting pin can be screwed into the threaded hole after passing through the through hole, which can also connect the feeding track to the output end of the driver. The workpiece to be conveyed is placed on the feeding track 20. The magnetic interaction between the electromagnet and armature inside the vibrator can convert electrical energy into mechanical vibration and transmit it to the transmission shaft at the output end of the vibrator. This drives the surface of the feeding track 20 to produce a small vibration, so that the workpiece on the feeding track 20 moves on the feeding track 20 with the vibration of the feeding track 20, thereby realizing the conveying of the workpiece.

[0028] Specifically, the first blowing assembly 30 is disposed on the first side of the feed end x1 of the feeding track 20, and the limiting block 40 is disposed on the second side of the feed end x1 of the feeding track 20, so that the first blowing assembly 30 and the limiting block 40 are arranged face to face. At least part of the top surface of the limiting block 40 is flush with the top surface of the feeding track 20, so that the limiting block 40 and the feeding track 20 are at the same horizontal height, ensuring that the feeding track 20 and the limiting block 40 cooperate to transport the workpiece smoothly. A first feeding channel 36 is formed between the first blowing assembly 30 and the limiting block 40, and the first feeding channel 36 is located on the top surface of the feeding track 20. When in use, it needs to be used in conjunction with an external feeding mechanism. For example, the vibrating feeding plate is used to transport the workpiece to the front of the first blowing component 30 and the limiting block 40. The linear vibrator drives the feeding track 20 to vibrate, so that the workpiece moves in the direction of the first blowing component 30 and the limiting block 40. Workpieces that are not aligned with the first feeding channel 36 will be blocked by the first blowing component 30 and the limiting block 40 and will not be able to enter the first feeding channel 36. They will fall back into the vibrating feeding plate. The first feeding channel 36 can be used to perform the initial screening of the workpiece. Then, the first blowing assembly 30 blows air onto the workpieces entering the first feeding channel 36. Combined with the vibrating feeding track 20, this separates stacked and closely spaced workpieces, preventing them from piling up. Finally, the workpieces are conveyed to the first side of the feeding end x1 of the feeding track 20, behind the first blowing assembly 30, at the aligning block 32. The aligning block 32 has an aligning face 321 on its side facing and close to the first blowing assembly 30. The aligning face 321 is arc-shaped. When the workpiece is vibrated to the aligning block 32, the outer surface of the workpiece... The curved surfaces 321 of the aligning block 32 come into contact with each other, causing the outer surface of the workpiece to move along the curved surfaces 321. The smaller contact area between the workpiece and the aligning block 21, and the fact that they are in curved contact, results in less friction and makes it easier for the workpiece to move along the surfaces 321. The surfaces 321 also provide a natural sliding path. The surfaces 321 enhance the guiding effect on the workpiece, thereby aligning it and allowing it to move on the feeding track 20 in the correct posture, effectively solving the problem of workpiece accumulation.

[0029] Preferred, such as Figure 1 and Figure 2As shown, the first blowing assembly 30 includes a first air plate 34 and a first air blowing driver. The first air plate 34 and the limiting block 40 form a first feeding channel 36. The first driver is an air pump. The first air plate 34 is disposed on the first side of the feeding end x1 of the feeding track 20 and is perpendicular to the top surface of the feeding track 20. The first air plate 34 has a first air hole 341. The first air blowing driver is connected to the first air hole 341 through a first air pipe 35. By using the first driver in conjunction with the first air pipe 35, air can be supplied to the first air hole 341. The air from the first air hole 341 is in conjunction with the vibrating feeding track 20, thereby separating workpieces that are stacked together or too close together.

[0030] Preferably, in some embodiments, such as Figures 1 to 2 The feeding mechanism also includes: multiple sliding rods 41; mounting holes 21 spaced apart on the feeding track 20; and through holes 42 spaced apart on the limiting block 40. The first end of each sliding rod 41 is disposed within the mounting hole 21, and the limiting block 40 is fitted onto the second end of each sliding rod 41 through the through holes 42. Specifically, by pulling the limiting block 40, the limiting block 40 slides on the sliding rod 41, allowing the limiting block 40 to move closer to or away from the feeding track 20, thereby changing the distance between the limiting block 40 and the first air plate 34 to form first feeding channels 36 of different sizes. Simultaneously, the distance between the mounting hole 21 and the through hole 42 is limited to be less than the size of the workpiece, thus meeting the conveying requirements of different workpieces. Furthermore, the limiting block 40 can be an L-shaped structure, with a portion of its top surface protruding upwards to prevent the workpiece from falling out of the first feeding channel 36.

[0031] Preferred, such as Figure 1 , Figure 2 and Figure 4As shown, a track clamping block 50 is provided on the first side of the middle section x3 of the feeding track 20, and a track stop block 51 is provided on the second side of the middle section x3 of the feeding track 20. The track clamping block 50 and the track stop block 51 form a second feeding channel. The straightening stop block 32 and the track clamping block 50 are both located on the first side of the feeding track 20. The straightening stop block 32 is located to the left front of the track stop block 51 and forms a gap between them. After the workpiece is straightened by the straightening stop block 32, the workpiece enters the middle section x3 of the feeding track 20 through the gap. Each workpiece enters the second feeding channel in sequence. The second feeding channel restricts each workpiece to prevent it from shaking or deviating when being fed by the feeding track 20. Along the conveying direction of the feeding track 20, a plurality of adjustment holes 22 are spaced apart on the top surface of the second side of the feeding track 20. The track stop 51 has an equal number of elongated holes 52 as the adjustment holes 22. By moving the track stop 51, different positions of the elongated holes 52 on the track stop 51 are aligned with the adjustment holes 22, thereby forming a second feeding channel of different sizes according to the size or specifications of the workpiece, so as to clamp workpieces of different sizes. It should be noted that after aligning the elongated holes 52 with the adjustment holes 22 as required, fasteners such as bolts are used. One end of the bolt passes through the elongated hole 52 and is connected to the adjustment hole 22, and the other end of the bolt is connected to the outer surface of the track stop 51, thereby fixing the adjusted track stop 51 on the feeding track 20.

[0032] Preferred, such as Figure 1 , Figure 4 and Figure 6 As shown, the feeding mechanism also includes a material handling component 60, which is located at the discharge end x2 of the feeding track 20. The material handling component 60 includes a first suction driver and a material handling element 61. The material handling element 61 has a suction chamber 62. Multiple first suction holes 63 communicating with the suction chamber 62 are formed on the outer surface of the end of the material handling element 61 near the feed end x1 of the feeding track 20. The first suction driver is connected to the suction chamber 62 via a first suction pipe 64. When a workpiece is transferred to the discharge end x2 and needs to be unloaded, the first suction driver, in conjunction with the first suction pipe 64, can draw gas out of the suction chamber 62 through the first suction holes 63, thereby generating suction near the first suction holes and drawing the workpiece to the unloading area of ​​the feeding mechanism. It should be noted that the first suction driver is an air pump.

[0033] Preferred, such as Figure 2 , Figure 4 and Figure 5As shown, the base 10 is also equipped with a rotary driver 12 and a slide 13. The rotary driver 12 is a motor. A pusher 121 is sleeved on the output end y of the rotary driver 12. The suction member 61 is slidably disposed on the slide 13. The pusher 121 abuts against the suction member 61. When unloading is required, the rotary driver 12 drives the pusher 121 to rotate. The pusher 121 squeezes the surface of the suction member 61 to push the suction member 61 to slide on the slide 13, thereby pushing the suction member 61, which has picked up the workpiece, to the unloading area of ​​the feeding mechanism. Then the air pump stops pumping air into the suction chamber 62, and the workpiece falls into the unloading area, thus completing the unloading operation.

[0034] Preferred, such as Figure 1 and Figure 2 As shown, a first detection element 70 is provided on the first side of the discharge end x2 of the feeding track 20. The detection end of the first detection element 70 extends into the second feeding channel. The first detection element 70 is used to detect whether there is a workpiece on the discharge end x2 of the feeding track 20. When the first detection element 70 detects that there is a workpiece on the discharge end x2 of the feeding track 20 and that it needs to be unloaded, the first detection element 70 sends the detection information to the control module of the feeding mechanism. The control module of the feeding mechanism issues an instruction to make the first suction driver and the rotary driver 12 start working, so that the suction member 61 picks up the material and is pushed to the unloading area by the pusher 121.

[0035] Preferably, the feeding mechanism further includes a material-fixing component 80, which includes a second suction driver and a material-fixing block 81. The material-fixing block 81 is disposed on the first side of the discharge end x2 of the feeding track 20, and a second suction hole 83 is provided on the material-fixing block 81. The second suction driver is connected to the side wall of the second suction hole 83 through a second suction pipe 82. When it is necessary to sample workpieces, in order to prevent workpieces from accumulating at the discharge end x2 of the feeding mechanism, the second suction driver, in conjunction with the second suction pipe 82, can suck up the workpieces for sampling inspection. The remaining workpieces continue to move along the feeding track 20, avoiding blockage of other workpieces during sampling inspection.

[0036] Preferably, the feeding mechanism further includes a second blowing assembly 90 and a throwing pipe 93. The second blowing assembly 90 includes a second air plate 91 and a second air blower. The second air plate 91 is disposed on the first side of the discharge end x2 of the feeding track 20 and is located behind the stationary assembly 80. The second air plate 91 has a second air hole 92. The second air blower is connected to the second air hole 92 through a second air pipe 94. The throwing pipe 93 is disposed on the second side of the discharge end x2 of the feeding track 20, and the inlet end of the throwing pipe 93 is aligned with the second air hole 92. When the second detection element 70 of the feeding mechanism detects a defective workpiece, the control module issues a command to drive the second air blower to cooperate with the second air pipe 94 to supply air into the second air hole 92, thereby blowing the defective workpiece into the throwing pipe 93.

[0037] Example 2

[0038] Unlike Embodiment 1, the track stop 51 is slidably disposed on the feeding track 20. A magnetic suction component is disposed on the outer surface of the feeding track 20, and a magnetic element is disposed on the bottom surface of the feeding track 20 at a position corresponding to the position of the magnetic suction component. The magnetic suction component and the magnetic element attract each other. By sliding and changing the position of the track stop 51 on the feeding track 20, the distance between the track stop 51 and the first air plate 34 can be changed, thereby changing the size of the first movable channel. Then, the magnetic suction component is used to attract the magnetic element, so that the track stop 51 is fixed on the feeding track 20, thus fixing the size of the second movable channel.

[0039] Preferably, the magnetic component includes: an energized coil, an iron core, and a power supply component. A placement cavity is provided within the feeding track 20, and the energized coil, iron core, and power supply component are all housed within the placement cavity. One end of the iron core protrudes from the placement cavity and is flush with the outer surface of the feeding track 20. The coil is sleeved on the iron core, and the power supply component is electrically connected to the coil. After the track stop 51 is positioned correctly on the feeding track 20, the power supply component energizes the iron core, causing the iron core to generate a magnetic force that attracts the magnetic component, thereby fixing the track stop 51 onto the feeding track 20. It should be noted that the power supply component is a power source, specifically a linear regulated power supply, such as the LM317 series, but other power sources capable of supplying power to the coil are also acceptable.

[0040] Preferably, a slider is provided at the bottom end of the track stop 51, and a groove is provided on the top surface of the feeding track 20, with the slider slidably disposed within the groove. The size of the second feeding channel can be stably adjusted by sliding within the slider using the groove.

[0041] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0042] Example 3

[0043] Unlike Embodiment 1, the second side of the feeding end of the feeding track 20 is internally equipped with multiple pusher drivers, and the output end y of the pusher drivers is driven and connected to the limiting block 40. The pusher drivers drive the limiting block 40 to move closer to or further away from the first air plate 34, thereby flexibly changing the size of the first feeding channel 36 to meet the screening requirements of workpieces of different specifications. The pusher drivers are electric push rods or cylinders; other types of drivers capable of pushing the limiting block 40 can also be used. Using electric push rods or cylinders to move the limiting block 40 is a common practice among those skilled in the art; therefore, its working principle and structure will not be described in detail.

[0044] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.
