[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached 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.

[0040] It is understood that the terms "first", "second", etc. used in the present application may be used herein to describe various components, but unless otherwise specified, these components are not limited by these terms. These terms are only used to distinguish a first component from another component.

[0041] As Figure 1 , Figure 6 and Figure 7 shown, in one embodiment, a stable chain conveyor device for automotive parts is proposed. The device includes:

[0042] Main frame 1: including a mounting plate 101 provided on the main frame 1;

[0043] Thrust mechanism 2: including a plurality of thrust rods 201 mounted on the mounting plate 101. A rotating gear 202 is fixedly installed on the surface of each thrust rod 201, and the rotating gear 202 meshes with a rack bar 203;

[0044] Magnetic attraction mechanism 3: used to drive the thrust rod 201 to limit the parts box;

[0045] Swing mechanism 4: used to accelerate the conveying speed of the parts box through the thrust rod 201;

[0046] Limit mechanism 5: used to limit the reset of the thrust rod 201;

[0047] Drive mechanism 7: used to drive the thrust rod 201 to drive the parts box to move;

[0048] Plate chain mechanism 8: used to support the parts box.

[0049] In the actual application of the embodiment of the present invention, when conveying the parts box, as Figure 1 shown, when moving from the lower plate chain line to the plate chain mechanism 8 at this time, it should be noted that although the parts box will slip due to the action of the plate chain mechanism 8, due to the pushing action of the lower plate chain line, the parts box will still change its posture upward following the plate chain mechanism 8. At this time, through the action of an external photoelectric sensor, when the parts box completely moves onto the plate chain mechanism 8, at this time, through the feedback of an electrical signal, as Figure 7 shown, from Figure 7When viewed from the front view direction, the rack bar 203 is driven to move upward by the action of the magnetic attraction mechanism 3. The upward movement of the rack bar 203 drives the rotating gear 202 to rotate counterclockwise, and then drives the thrust rod 201 to rotate. The opposing thrust rods 201 rotate synchronously. At this time, the descending parts box is blocked by the thrust rod 201 and moves upward. The support of the thrust rod 201 enables the parts box to be smoothly conveyed during the ascending stage, achieving the purpose of avoiding slipping. At the same time, the movement of the magnetic attraction mechanism 3 drives the swing mechanism 4 to move. At this time, under the action of the drive mechanism 7, the magnetic attraction mechanism 3 increases the moving speed of the thrust rod 201 along the plate chain mechanism 8, thereby achieving the function of quickly separating the parts boxes and avoiding collision and extrusion between the parts boxes.

[0050] As Figure 8 and Figure 12 shown, as a preferred embodiment of the present invention, the magnetic attraction mechanism 3 includes an electromagnet 301 installed on the mounting plate 101, and further includes a plurality of magnetic balls 302 installed on the mounting plate 101. The magnetism carried by the electromagnet 301 after being energized is different from that of the magnetic balls 302. Each magnetic ball 302 passes through the fixed frame 305 and is slidably connected to the fixed frame 305. A swing rod 303 is rotatably connected to the surface of the magnetic ball 302. One end of the swing rod 303 away from the magnetic ball 302 is rotatably connected to the rack bar 203. The rack bar 203 is connected to the fixed frame 305 through a tension spring 304, and the rack bar 203 is slidably connected to the fixed frame 305.

[0051] In the actual application of the embodiment of the present invention, when the parts box moves onto the plate chain mechanism 8, at this time, through the electrical signal feedback by the induction photoelectric, as Figure 12 shown, at this time the electromagnet 301 is powered on. The electromagnet 301 generates a magnetic attraction for the magnetic balls 302 instantaneously after being powered on. As Figure 8 shown, when viewed from the Figure 8 front view direction, at this time the magnetic balls 302 move to the right. The movement of the magnetic balls 302 drives the swing rod 303 to swing. As Figure 7 shown, and then drives the rack bar 203 to move upward, causing the thrust rod 201 to rotate, playing a role of limiting and supporting the parts box.

[0052] As Figure 8As shown, as another preferred embodiment of the present invention, the swing mechanism 4 includes an L-shaped connecting rod 401 whose inner wall is fixedly connected to the magnetic ball 302. The surface of the L-shaped connecting rod 401 is penetrated by a sliding ball rod 402 and is slidably connected to the sliding ball rod 402. The sliding ball rod 402 is connected to the L-shaped connecting rod 401 through a compression spring 403. The sliding ball rod 402 is in contact with two sliding ramps 404. Each sliding ramp 404 is fixedly installed on a fixed frame 305. The fixed frame 305 is fixedly installed on a connecting block 410. The sliding ball rod 402 is in contact with the inner wall of a chute opened on a sliding plate 405. The sliding plate 405 is slidably connected to the connecting block 410. First and second ratchet gears 406 and 407 are respectively fixedly installed at both ends of the sliding plate 405. A toggle rod 408 is rotatably connected to the surface of the sliding plate 405. One end of the toggle rod 408 away from the sliding plate 405 is rotatably connected to a moving block 413. A toggle spring 409 is connected between the sliding plate 405 and the moving block 413. The moving block 413 is slidably connected to the inner wall of the connecting block 410. The connecting block 410 is fixedly installed on the surface of a circulating belt 411. Both ends of the circulating belt 411 are sleeved on a belt runner 412. The belt runner 412 is rotatably connected to the inner wall of a mounting plate 101.

[0053] In the actual application of the embodiment of the present invention, when the magnetic attraction mechanism 3 moves, such as Figure 8As shown, at this time, the magnetic ball 302 drives the L-shaped connecting rod 401 to move to the right, and then drives the sliding plate 405 to move to the right through the sliding ball rod 402. The rightward movement of the sliding plate 405 causes the first ratchet gear 406 to disengage from the driving mechanism 7, and at the same time, the second ratchet gear 407 engages with the driving mechanism 7. At this time, under the action of the driving mechanism 7, the movement speed of the connecting block 410 is increased. The purpose of setting the first ratchet gear 406 and the second ratchet gear 407 as ratchet gears is that when the speed is increased under the action of the driving mechanism 7, the speed of the first ratchet gear 406 also increases accordingly. Through the action of the ratchet gear, the teeth of other first ratchet gears 406 are toggled with the driving mechanism 7 to avoid affecting the speed-up movement of the driving mechanism 7. The driving mechanism 7 speeds up the movement speed of the thrust rod 201 to push the parts box, achieving the purpose of quickly separating the parts boxes. It should be noted here that during the process of the sliding ball rod 402 pushing the sliding plate 405 to move to the right, the toggle spring 409 is continuously compressed by extrusion. When reaching the swing limit of the toggle rod 408, at this time, under the action of the toggle spring 409, it moves to the right instantaneously, causing the second ratchet gear 407 to engage with the driving mechanism 7. At the same time, the sliding ball rod 402 continuously rises under the action of the sliding ramp 404. After the sliding plate 405 suddenly moves to the right, the sliding ball rod 402 gradually disengages from the chute on the sliding plate 405 through the sliding ramp 404. Thus, when the sliding plate 405 is reset later, it will not be interfered by the sliding ball rod 402. At the same time, through the setting of the compression spring 403, the sliding ball rod 402 slides on the surface of the sliding plate 405 during reset, without causing hard extrusion.

[0054] As Figure 10 , Figure 11 , Figure 12 and Figure 13 shown, as another preferred embodiment of the present invention, the limiting mechanism 5 includes a limiting plate 501 fixedly installed on the mounting plate 101. An electromagnet 301 is fixedly installed on the surface of the limiting plate 501. A U-shaped groove 502 and a straight groove 503 are formed on the limiting plate 501, and both ends of the straight groove 503 are respectively connected to the two U-shaped grooves 502.

[0055] In the actual application of the embodiment of the present invention, when the magnetic ball 302 moves under the attraction of the electromagnet 301, as Figure 12As shown, at this time, with the movement of the driving mechanism 7, the magnetic ball 302 passes through the U-shaped groove 502. When the electromagnet 301 is powered off, the magnetic ball 302 is limited by the linear groove 503 and cannot be reset under the action of the tension spring 304. It should be noted here that the electromagnet 301 will only be energized for a short time. When the thrust rod 201 supports the part box to move upward, the magnetic ball 302 moves synchronously. When it moves to the linear groove 503, the electromagnet 301 is powered off to prevent the subsequent movement of the magnetic ball 302 from being attracted and causing the thrust rod 201 to swing, thereby affecting the movement of the part box from the lower plate chain line to the plate chain mechanism 8. When the thrust rod 201 pushes the part box from the plate chain mechanism 8 to the higher plate chain line, as shown in FIG. Figure 13 As shown, at this time, the magnetic ball 302 is released from the limit and reset by the U-shaped groove 502 at the other end connected by the straight groove 503, thereby avoiding the motion interference between the thrust rod 201 and the high plate chain line.

[0056] like Figure 2 and Figure 3 As shown, as another preferred embodiment of the present invention, the device also includes an extrusion mechanism 6, which includes an extrusion block 601 fixedly mounted on the inner wall of the mounting plate 101, and the surface of the extrusion block 601 is provided with an arc surface that cooperates with the sliding plate 405 to slide.

[0057] In practical application, the embodiment of the present invention is as follows: Figure 3 As shown, from Figure 3 When viewed from the front, after the driving mechanism 7 completes the acceleration and elevation of the thrust rod 201 for a certain distance, the sliding plate 405 comes into contact with the extrusion block 601, and the sliding plate 405 is squeezed to move to the left by the trajectory of the extrusion block 601, and then reset by the toggling action of the swing mechanism 4, thereby reducing the speed at which the parts box is pushed by the thrust rod 201. When the parts box is transported again on the plate chain mechanism 8, the speed is increased again, thereby increasing the distance between the parts boxes to avoid transportation extrusion.

[0058] like Figure 4 , Figure 5 , Figure 14 and Figure 15As shown, as another preferred embodiment of the present invention, the driving mechanism 7 includes a driving motor 701 fixedly mounted on the mounting plate 101, the output end of the driving motor 701 passes through the mounting plate 101 and is rotatably connected to the mounting plate 101, the output end of the driving motor 701 is coaxially fixedly mounted with a large gear 702 and a small gear 703, the large gear 702 is meshed with a follower gear 704, the follower gear 704 is fixedly mounted on the surface of the outer transmission shaft 710, the surface of the follower gear 704 is sleeved with a first chain 705, and the side of the first chain 705 is provided with a The teeth of the two ratchet gears 407 match each other, the pinion 703 meshes with the plate chain gear 706, the plate chain gear 706 is fixedly mounted on the surface of the plate chain shaft 707, the plate chain gear 706 is rotatably connected to the inner wall of the mounting plate 101, the outer transmission shaft 710 passes through the plate chain shaft 707 and is rotatably connected to the plate chain shaft 707, the plate chain shaft 707 is rotatably connected to the belt pulley 412, the surface of the plate chain shaft 707 is sleeved with a main chain 708, the surface of the main chain 708 is fixedly mounted with a second chain 709, the second chain 709 meshes with the first ratchet gear 406.

[0059] In practical application of the embodiment of the present invention, when transporting the parts box, Figure 15 As shown, at this time, the driving motor 701 starts to run, and the driving motor 701 drives the large gear 702 and the small gear 703 to rotate, and then drives the follower gear 704 and the plate chain gear 706 to rotate through the meshing action. Since the large gear 702 transmits to the follower gear 704 from a large radius to a small radius, and the small gear 703 transmits to the plate chain gear 706 from a small radius to a large radius, the rotation speed of the follower gear 704 is greater than the rotation speed of the plate chain gear 706, that is, the rotation speed of the first chain 705 is greater than the rotation speed of the second chain 709, so that when the swing mechanism 4 is driven to engage the second ratchet gear 407 with the first chain 705, it accelerates at this time, and at the same time drives the plate chain mechanism 8 to perform cyclic conveying through the transmission action of the main chain 708.

[0060] like Figure 9 As shown, as another preferred embodiment of the present invention, the plate chain mechanism 8 includes a plurality of chain blocks 801 fixedly mounted on the main chain 708, a movable support plate 802 is fixedly mounted on the surface of the chain block 801, and a plurality of rotating rollers 803 are rotatably mounted on the inner wall of the movable support plate 802.

[0061] In practical application, the embodiment of the present invention is as follows: Figure 9 As shown, when the thrust rod 201 pushes the part box to move upward, although the speed of the chain block 801 is low, the part box is rolled on the rotating roller 803 by the setting of the movable support plate 802, thereby increasing the conveying speed of the part box.

[0062] The technical features of the above-described embodiments may be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0063] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
