[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] A feeding device, such as Figure 1As shown, it includes a vibration plate 1, a material rail 2, a discharge mechanism 3, a first conveying mechanism 4 and a second conveying mechanism 5. The discharge port of the vibration plate 1 is connected to the discharge mechanism 3 through the material rail 2. The parts are poured into the vibration plate 1, arranged by the vibration plate 1, and guided into the discharge mechanism 3 through the material rail 2. The first conveying mechanism 4 is arranged below the discharge mechanism 3, and the parts are discharged one by one through the discharge mechanism 3 and fall into the first conveying mechanism 4 below it, and the first conveying mechanism 4 is used to move the single parts horizontally. The second conveying mechanism 5 is arranged on one side of the first conveying mechanism 4, and the second conveying mechanism 5 is used to take out the parts on the first conveying mechanism 4 and transfer them to the target position (the processing station of the processing equipment).

[0031] In one embodiment, the material rail 2 includes a hard groove rail 21 and a hose 22, one end of the hard groove rail 21 is connected to the vibration plate 1, and the other end is connected to one end of the hose 22, and the other end of the hose 22 is connected to the discharge mechanism 3. The hard groove rail 21 allows the parts to be arranged in order; the hose 22 is connected to reduce the vibration of the vibration plate 1 from being transmitted to the discharge mechanism 3, causing the discharge mechanism 3 to shake; and the shaking of the discharge mechanism 3 may cause the connection between the parts of the discharge mechanism 3 to become loose; it may also cause the parts to fail to fall accurately onto the first conveying mechanism 4.

[0032] In one embodiment, if Figure 3-5As shown, the material discharge mechanism 3 includes a material discharge bracket 31, a material storage block 32, a baffle 33, a first actuator 34, a first gripper cylinder 35 and a gripper 36. The material storage block 32 is arranged on the material discharge bracket 31. A guide hole 321 for guiding the parts to fall is provided in the vertical direction of the material storage block 32, and side holes 322 connected to the guide hole 321 are provided on the two symmetrical side walls of the material storage block 32. The gripper 36 is arranged in the side hole 322. The first gripper cylinder 35 is fixed on the material discharge bracket 31, and its output end is connected to the gripper 36. The first gripper cylinder 35 controls the gripper 36 arranged in the side hole 322 to move toward and away from each other, thereby realizing the clamping or release of the parts in the guide hole 321. The top of the guide hole 321 is connected to the hose 22, the baffle 33 is slidably arranged at the bottom of the guide hole 321, the first actuator 34 is arranged on the discharge bracket 31, and its output end is connected to the baffle 33, and the baffle 33 is driven by the first actuator 34 to move horizontally, thereby opening or closing the bottom of the guide hole 321. Among them, the first actuator 34 can be a cylinder. When in use, the first actuator 34 drives the baffle 33 to close the bottom of the guide hole 321, and the parts are arranged by the vibration plate 1 and then transmitted to the storage block 32 through the material rail 2, and are sequentially stacked and stored in the guide hole 321. The first clamping cylinder 35 drives the clamping hand 36 to clamp the second to last part, and then open the bottom of the guide hole 321, and the last part falls into the first conveying mechanism 4; then the guide hole 321 is closed again, and the clamping hand is opened, so that the parts fall onto the baffle 33. Repeat the above operation to discharge the parts one by one.

[0033] In a preferred embodiment, if Figure 3-5 As shown, the side hole 322 is a waist-shaped hole arranged vertically. When producing parts of different heights, it is only necessary to adjust the upper and lower positions of the clamping hand 36 so that the clamping hand 36 can clamp the second to last part.

[0034] In one embodiment, if Figure 6 As shown, the first conveying mechanism 4 includes a first cylinder 41, a second cylinder 42 and a receiving tray 43. The second cylinder 42 is arranged on the first cylinder 41, and the first cylinder 41 is used to drive the second cylinder 42 to move horizontally. The receiving tray 43 is arranged on the second cylinder 42, and the second cylinder 42 is used to drive the receiving tray 43 to move horizontally. The receiving tray 43 is provided with a mold mounting position 44 for mounting and matching parts of different sizes. Different molds are selected on the mold mounting position according to parts of different sizes. Specifically, the mold mounting position is a recessed mounting groove, the mold is placed in the mounting groove, and the mold is fixed to the mold mounting position by screws. Through the dual-cylinder structure design, the two cylinders are driven to one side synchronously, which increases the moving speed and thus improves the transmission efficiency.

[0035] In one embodiment, if Figure 7As shown, the second conveying mechanism 5 includes a clamping mechanism 51 and a moving device 52 . The moving device 52 drives the clamping mechanism 51 to move up and down and horizontally; the parts are grasped by the clamping mechanism 51 .

[0036] like Figure 8 As shown, the clamping mechanism 51 includes a clamping cylinder 511 and a clamping claw 512. The clamping claw 512 is arranged on the clamping cylinder, and the clamping claw is driven to move by the clamping cylinder.

[0037] like Figure 9-10 As shown, the moving device 52 includes a mounting bracket 521, a first guide rail 522, a second guide rail 523, a connecting block 524, a guide plate 525, a driving block 526, a guide column 527 and a rotating cylinder 528. The first guide rail 522 is horizontally arranged on the mounting bracket 521, the connecting block 524 is slidably arranged on the first guide rail 522, the second guide rail 523 is vertically and slidably arranged on the connecting block 524, and the clamping mechanism 51 is arranged at the lower end of the second guide rail 523. The horizontal and vertical movements of the clamping mechanism 51 are realized by the first guide rail 522 and the second guide rail 523. The guide plate 525 is arranged on the mounting bracket 521, and a guide groove 529 is arranged on the guide plate 525. One end of the guide column 527 is fixed on the second guide rail 523, and the other end is placed in the guide groove 529. The driving block 526 is respectively connected to the rotating cylinder 528 and the guide column 527. The driving block 526 is driven by the rotating cylinder 527 to push the guide column 527 to move in the guide groove 529.

[0038] The trajectory of the guide groove 529 is the trajectory of the clamping mechanism 51. Figure 9-11 As shown, in one embodiment, the guide groove 529 is composed of three sections, namely, the first section guide groove 5291 and the third section guide groove 5293 are arranged vertically and in parallel, and the second section guide groove 5292 is arranged horizontally to connect the upper ends of the first section guide groove 5291 and the third section guide groove 5293, which are combined into an inverted U-shaped structure; the first section guide groove 5291 and the third section guide groove 5293 guide the clamping mechanism 51 to move up and down, and the second section guide groove 5292 guides the clamping mechanism 51 to move horizontally; in addition, the horizontal movement distance of the clamping mechanism 51 can be changed by changing the length of the second section guide groove 5292. Preferably, the second section guide groove 5292 is connected to the first section guide groove 5291 and the third section guide groove 5293 respectively in an arc-shaped structure; in this way, the moving direction of the clamping mechanism 51 can be switched more smoothly.

[0039] In one embodiment, if Fig.11As shown, in order to achieve adjustable horizontal movement distance of the clamping mechanism 51, the guide plate 525 includes a left plate 5251, a middle plate 5252 and a right plate 5253, and the guide groove 529 is formed by splicing the left plate 5251, the middle plate 5252 and the right plate 5253. Specifically, the left plate 5251 and the right plate 5253 are respectively provided with a first section guide groove 5291 and a third section guide groove 5293, and the middle plate 5252 is provided with a second section guide groove 5292.

[0040] In one embodiment, if Figure 9-12 As shown, a limiting mechanism is also included, and the limiting mechanism is used to limit the downward movement distance of the second guide rail 523. Specifically, the limiting mechanism includes a limiting block 531 and a stopper 532, the stopper 532 is fixedly arranged on the mounting bracket 521, and the limiting block 531 is arranged on the second guide rail 523. In a specific embodiment, the limiting block 531 includes a body 5311 and a limiting portion 5312 extending horizontally to both sides of the body 5311; the whole is T-shaped; the body is used to be fixed to the second guide rail 523, and the limiting portion 5312 is blocked by the stopper 532, so that the clamping mechanism 51 cannot continue to move downward.

[0041] In one embodiment, if Figure 9-12 As shown, it also includes a screw 541, a pressure pad 542 and a nut 543. The limiting portion 5312 is vertically provided with a screw hole, the screw 541 is arranged in the screw hole, the pressure pad 542 is arranged at the lower end of the screw 541, and the nut 543 is arranged on the screw 541 to lock and fix the screw 541. When it is necessary to adjust the downward position of the clamping jaw mechanism 51, the upper and lower positions of the stopper 532 can be adjusted. However, the position adjustment of the stopper 532 is cumbersome; therefore, through the above structure, adjusting the pressure pad 542 to a position can play the same role; in addition, by converting the rotational motion of the screw 541 into linear motion, the adjustment is convenient and fine-tuning can be achieved. Each rotation of one circle realizes the movement of one pitch. The screw 541 can be quickly locked by the nut 543.

[0042] In one embodiment, if Figure 9-12 As shown, it also includes a hydraulic buffer rod 55, which is arranged on the block 532; the hydraulic buffer rod 55 is arranged so that in the next process after the pressure pad 542 contacts the hydraulic buffer rod 55, the clamping mechanism 51 can slowly descend, thereby reducing the degree of shaking of the clamping mechanism 51 when it approaches the target position.

[0043] In one embodiment, if Figure 9-13 As shown, the driving block 526 includes a driving body 5261 and a fixing hole 5262 and a waist-shaped hole 5263 arranged on the driving body 5261. The driving block 526 is fixed to the rotating cylinder 528 by passing a screw through the fixing hole 5262; the guide column 527 is placed in the waist-shaped hole 5263, and the guide column 527 is pushed to move through the side walls of the waist-shaped hole 5263.

[0044] When the present invention is used, Figure 1-14 As shown, Fig.14 The structural diagram of the parts is shown in FIG. 1. The vibration plate 1 arranges the parts and then feeds them into the discharge mechanism 3 through the material rail 2. The discharge mechanism 3 drops the parts one by one into the mold of the first conveying mechanism 4. The parts are then conveyed to the bottom of the second rotating mechanism 5 by the first conveying mechanism. The rotating cylinder rotates clockwise to drive the driving block 526 to rotate clockwise, pushing the guide column 527 to move downward in the guide groove 529 until it contacts the hydraulic buffer rod 55. The guide column 527 is slowly lowered by the buffering force of the hydraulic buffer rod 55, reducing the shaking degree of the second guide rail 523. The parts are grasped by the clamping mechanism 51, and then the driving block 526 is reversely driven by the rotating cylinder 528 to rotate counterclockwise, pushing the guide column 527 to move in the guide groove 529, and passing through the third section of the guide groove 5293 in sequence, that is, moving up, translating and moving down. After the parts are moved to the specified position, the clamping mechanism 51 is opened, and then the rotating cylinder 528 rotates clockwise again, and the above actions are repeated.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should all be included in the protection scope of the claims of the present invention.
