DETAILED DESCRIPTION

[0039] 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 intended to limit the present invention.

[0040] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0041] like Figure 1 , Figure 6 and Figure 7 As shown, in one embodiment, a stable chain conveying device for automobile parts is provided, the device comprising:

[0042] The main frame 1 includes a mounting plate 101 disposed on the main frame 1;

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

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

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

[0046] Limiting mechanism 5: used to limit the thrust rod 201 from resetting;

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

[0048] Plate chain mechanism 8: used for supporting the parts box.

[0049] In practical application, when the parts box is transported, Figure 1 As shown, when the plate chain line at the lower position moves to the plate chain mechanism 8, it should be noted that although the plate chain mechanism 8 causes the parts box to slip, due to the pushing effect of the plate chain line at the lower position, the parts box will still change its posture upward following the plate chain mechanism 8. At this time, through the action of the external photoelectric sensor, when the parts box completely moves to the plate chain mechanism 8, the feedback of the electrical signal is performed, as shown in FIG. Figure 7 As shown, from Figure 7From the front view, the rack rod 203 is driven to move upward by the action of the magnetic attraction mechanism 3, and the upward movement of the rack rod 203 drives the rotating gear 202 to rotate counterclockwise, thereby driving the thrust rod 201 to rotate, and the opposite thrust rod 201 rotates synchronously. At this time, the sliding part box is blocked by the thrust rod 201 and moves upward. The supporting effect of the thrust rod 201 allows the part box to be smoothly transported during the ascending stage to avoid 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 driving 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 effect of quickly separating the part boxes and avoiding collision and extrusion between the part boxes.

[0050] like Figure 8 and Fig.12 As 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 also includes a plurality of magnetic balls 302 installed on the mounting plate 101, and the magnetism of the electromagnet 301 after being energized is different from that of the magnetic ball 302, each magnetic ball 302 passes through the fixed frame 305 and is slidably connected to the fixed frame 305, and the surface of the magnetic ball 302 is rotatably connected to a swing rod 303, and one end of the swing rod 303 away from the magnetic ball 302 is rotatably connected to the rack rod 203, the rack rod 203 is connected to the fixed frame 305 through a tension spring 304, and the rack rod 203 is slidably connected to the fixed frame 305.

[0051] In actual application of the embodiment of the present invention, when the parts box moves to the plate chain mechanism 8, the electrical signal fed back by the induction photoelectric sensor is Fig.12 As shown, at this time, the electromagnet 301 is energized, and the electromagnet 301 generates magnetism to attract the magnetic ball 302 instantly after being energized, as shown in FIG. Figure 8 As shown, from Figure 8 From the front view direction, the magnetic ball 302 moves to the right, and the movement of the magnetic ball 302 drives the swing rod 303 to swing. Figure 7 As shown, the rack rod 203 is driven to move upward so that the thrust rod 201 rotates, thereby providing a limiting support for the parts box.

[0052] like 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, a sliding ball rod 402 passes through the surface of the L-shaped connecting rod 401 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 mounted on a fixed frame 305, the fixed frame 305 is fixedly mounted on a connecting block 410, the sliding ball rod 402 is in contact with the inner wall of a sliding groove provided on a sliding plate 405, and the sliding plate 405 is in contact with the connecting rod 401. The connecting block 410 is slidably connected, and the first ratchet gear 406 and the second ratchet gear 407 are fixedly installed at both ends of the sliding plate 405, and the surface of the sliding plate 405 is rotatably connected with a toggle rod 408, and the end of the toggle rod 408 away from the sliding plate 405 is rotatably connected to the moving block 413, and the sliding plate 405 and the moving block 413 are connected by a toggle spring 409, and the moving block 413 is slidably connected to the inner wall of the connecting block 410, and the connecting block 410 is fixedly installed on the surface of the circulating belt 411, and the two ends of the circulating belt 411 are mounted on the belt pulley 412, and the belt pulley 412 is rotatably connected to the inner wall of the mounting plate 101.

[0053] In practical application of the embodiment of the present invention, when the magnetic attraction mechanism 3 moves, Figure 8As shown, at this time, the magnetic ball 302 drives the L-shaped connecting rod 401 to move rightward, and then the sliding ball rod 402 drives the sliding plate 405 to move rightward. 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 is engaged with the driving mechanism 7. At this time, the movement speed of the connecting block 410 is accelerated under the action of the driving mechanism 7. 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 by the action of the driving mechanism 7, the speed of the first ratchet gear 406 is also increased. Through the action of the ratchet gear, the teeth of the other first ratchet gear 406 are toggled with the driving mechanism 7 to avoid affecting the speed-up movement of the driving mechanism 7. The driving mechanism 7 accelerates the movement speed of the thrust rod 201 to push the parts box, so as to achieve rapid separation between the parts boxes. It should be noted that, in the process of pushing the sliding plate 405 to move to the right by the sliding ball rod 402, the toggle spring 409 is squeezed so that the toggle spring 409 is continuously compressed. When the toggle rod 408 reaches its swing limit, it instantly moves to the right under the action of the toggle spring 409, so that the second ratchet gear 407 is engaged with the driving mechanism 7. At the same time, the sliding ball rod 402 continues to rise 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 sliding groove on the sliding plate 405 through the sliding ramp 404, so that when the sliding plate 405 is reset at a later stage, 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 when resetting, and no hard squeezing occurs.

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

[0055] In practical application of the embodiment of the present invention, when the magnetic ball 302 is attracted by the electromagnet 301, Fig.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. Fig.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 , Fig.14 and Fig.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, Fig.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 Fig. 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: Fig. 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 arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
