A blanking and arranging device for a fully automatic assembly machine for wheel screws

Abstract

The present invention discloses a blanking and arranging device for a fully automatic assembly machine for wheel screws, which belongs to the technical field of wheel screw assembly and includes a main board, the upper end of which is rotatably connected to a detection carrier, and a blanking mechanism is installed around the detection carrier. The blanking mechanism includes a driving mechanism and a blanking assembly arranged below the driving mechanism for receiving materials, and the blanking assembly can be used as an arrangement mechanism for transporting materials in a certain state. In order to allow the head and tail of the wheel screw to be arranged in the same manner, the initial height of the connecting rod and the bottom of the blanking frame is less than the height of the screw head. Therefore, when the wheel screw passes through the through-cavity formed by the connecting rod and the bottom of the blanking frame under the action of kinetic energy, the larger head will be confined in the through-cavity, but under the action of kinetic energy, the tail will still pass through the through-cavity to the lower end of the connecting rod, thereby achieving the effect of neatly arranging the entire screw on the through-cavity.

Technical Field

[0001] The invention relates to the technical field of wheel screw assembly, in particular to a blanking and arranging device of a fully automatic wheel screw assembly machine. Background Art

[0002] The working principle of the wheel screw automatic assembly machine is to clamp the workpiece into the mold through the vibration plate, feeding device and loading device, and then the turntable runs to the pre-locking station to pre-lock the screws and nuts. After the pre-locking is completed, it enters the screw locking station and judges the good and defective products by the locking torque and stroke.

[0003] During the process of completing the above actions, there is a process of placing the locked materials into a collecting device. Because the screw parts have a head and a tail, if they are placed directly into the collecting device, the screws will be randomly arranged inside the collecting bin, which will affect the stacking space of the screws and their subsequent use to a certain extent.

[0011] As a further solution of the present invention: wherein, a reset spring is provided between the connecting rod and the sliding groove, and in the initial state of the reset spring, the distance between the connecting rod and the bottom of the blanking frame is just the height of the through cavity.

[0012] As a further solution of the present invention: wherein, slots are provided on both sides of the connecting arm at a distance away from the connecting rod and less than half the length of the connecting arm, and a support frame is slidably connected to the slots, and the bottom of the support frame is fixedly connected to the bottom of the blanking frame.

[0013] As a further solution of the present invention: wherein, the contact surface of the receiving plate is configured as an arc-shaped structure with an arc, and the upward curved arc surface can slow down the screw.

[0015] As a further solution of the present invention: wherein, the movement trajectory of the material moving rod is arc-shaped, and when the material moving rod moves to the lowest point, it can move the screw on the bottom of the blanking frame.

[0016] As a further solution of the present invention: wherein, the driving mechanism includes a support column, the bottom of the support column is fixedly mounted on the main board, a connecting plate is provided on the top of the support column, a fixed plate is fixedly mounted on the end face of the connecting plate away from the support column, a movable plate that can move forward and backward is fixedly mounted on the bottom of the fixed plate, a clamping mechanism is fixedly mounted on the inner side of the movable plate, and the clamping mechanism includes a clamping column that can clamp and fix the screws.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the fully automatic wheel bolt assembly machine of this embodiment, when the wheel bolt is clamped by the clamping column and moved backward into the upper area of ​​the blanking assembly, the clamping column releases the clamping force, and the wheel bolt falls into the blanking frame, that is, onto the receiving plate. The receiving plate's cushioning effect can not only reduce the impact force generated by the bolt's free fall under the action of gravity, but also protect the durability of the blanking frame bottom. In addition, the receiving plate made of rubber material can protect the receiving plate through the cushioning effect and deformability of the rubber material, while also cushioning the impact force of the bolt's fall.

[0019] 2. In the fully automatic assembly machine for wheel screws in this embodiment, after the wheel screw enters the interior of the blanking frame, in order to arrange the head and tail of the wheel screw in the same manner, the initial height of the connecting rod and the bottom of the blanking frame is smaller than the height of the screw head. Therefore, when the wheel screw passes through the through cavity formed by the connecting rod and the bottom of the blanking frame under the action of kinetic energy, the larger head will be confined in the through cavity, but under the action of kinetic energy, the tail will still pass through the through cavity to the lower end of the connecting rod, thereby achieving neat arrangement of the entire screw on the through cavity, that is, the screw head is on top and the screw tail is on the bottom.

[0020] 3. In the fully automatic assembly machine for wheel screws in this embodiment, when the previous screw enters the through-hole, the next screw will continue to be released from the clamping column and fall into the receiving plate. After the receiving plate is hit by the screw, it will be subjected to a downward impact force. Combined with the action of the connecting arms on both sides, the connecting arms will rotate with the support frame as the fulcrum, thereby changing the height of the through-hole. When the height of the through-hole is greater than the diameter of the screw head, the wheel screw will keep the head up and the tail down and slide out of the blanking frame. In summary, this device can achieve the effect of fully automatic arrangement and collection of screws, and can cooperate with the assembly inspection machine to achieve the effect of collecting materials without the need for an additional power mechanism.

[0021] 4. The fully automatic assembly machine for wheel screws in this embodiment will drive the rotating gear to rotate through the above-mentioned movement. During the rotation process, the rotating gear will drive the fixed rods on both sides to deflect, and a material shifting rod is fixedly installed at the bottom of the fixed rod. When the fixed rod is deflected, it will synchronously drive the material shifting rod to approach the bottom of the flat area of ​​the lower material frame, thereby shifting the previous screw so that it leaves the flat area and enters the collection box.

[0034] See also Figure 1, which is a schematic diagram of the overall structure of this embodiment. The device includes a main sheet metal and a main board 10 installed inside the main sheet metal. The upper end of the main board 10 is rotatably connected to a test carrier 20. In addition to the blanking mechanism installed around the test carrier 20, there are also a loading mechanism, a pre-tightening station, a locking station 1, a locking station 2, a good product station, and a defective product station, from the left in a clockwise direction. The blanking mechanism is installed at the good product station and is used to accept products that meet production conditions. In this embodiment, the screws are transported to the test carrier 20 by starting the loading mechanism. The material screws are driven by the rotation of the test carrier 20. When the screws are transmitted to the locking stations 1 and 2, the two screws on the test carrier 20 are tightened respectively. After being tightened, they pass the inspection station. If they pass the inspection, they are discharged from the good product station. Unqualified screws will be classified and collected in the defective station. With the cooperation of the above device and the automation system module, fully automatic wheel screw locking assembly can be achieved.

[0035] like Figure 1 As shown, the blanking mechanism includes a driving mechanism 30 and a blanking assembly 40 arranged below the driving mechanism 30 for receiving the material. The driving mechanism 30 includes a support column 31, the bottom of the support column 31 is fixedly mounted on the main board 10, the top of the support column 31 is provided with a connecting plate 32, the end face of the connecting plate 32 away from the support column 31 is fixedly mounted with a fixing plate 33, the bottom of the fixing plate 33 is fixedly mounted with a movable plate 34 that can move forward and backward, and the inner side of the movable plate 34 is fixedly mounted with a clamping mechanism 35, and the clamping mechanism 35 includes a clamping column 36 that can clamp and fix the screws. In this embodiment, the control system controls the clamping column 36 to clamp the screws on the detection carrier 20, and then controls the movable plate 34 to move forward or backward to realize the transportation of the screws on the detection carrier 20 to the blanking assembly 40. The effect of material screw transportation is realized.

[0036] Moreover, in the above embodiment, the blanking assembly 40 includes a blanking frame 41 inclined downward, and the blanking frame 41 inclined downward can increase the falling speed of the screw, so that the gravitational potential energy after it falls from the clamping column 36 into the blanking frame 41 can be converted into kinetic energy sliding down the inclined surface.

[0037] like Figure 1 、 Figure 2 and Figure 4As shown, vertically distributed sliding slots 42 are provided on the front and rear sides of the blanking frame 41, and a connecting rod 43 is provided between the two sliding slots 42. Connecting arms 44 are fixedly mounted on both sides of the connecting rod 43. A receiving plate 45 for receiving the screw is fixedly mounted on the end face of the connecting arm 44 away from the connecting rod 43. In this embodiment, when the wheel screw is clamped by the clamping column 36 and moved backward into the upper area of ​​the blanking assembly 40, the clamping column 36 releases the clamping force, and the wheel screw falls into the blanking frame 41, that is, falls onto the receiving plate 45. The cushioning effect of the receiving plate 45 can not only reduce the impact force generated by the screw's free fall under the action of gravity, but also protect the durability of the bottom of the blanking frame 41.

[0038] In this embodiment, the receiving plate 45 can be made of rubber material. Due to the characteristics of the rubber material, on the one hand, it can play a buffering role. On the other hand, its elastic and deformable characteristics can be used to avoid screw collisions to produce pits, which affects the appearance.

[0039] like Figure 8 As shown, after the wheel screw enters the interior of the blanking frame 41, in order to allow the head and tail of the wheel screw to be arranged in the same manner, the initial height of the connecting rod 43 and the bottom of the blanking frame 41 is less than the height of the screw head. Therefore, when the wheel screw passes through the through cavity 43a formed by the connecting rod 43 and the bottom of the blanking frame 41 under the action of kinetic energy, the larger head will be confined in the through cavity 43a, but under the action of kinetic energy, the tail will still pass through the through cavity 43a to the lower end of the connecting rod 43, thereby realizing the neat arrangement of the entire screw on the through cavity 43a, that is, the screw head is on the top and the screw tail is on the bottom.

[0040] In order to realize the automation of the discharge mechanism, a return spring 43b is provided between the connecting rod 43 and the sliding groove 42. In the initial state of the return spring 43b, the distance between the connecting rod 43 and the bottom of the discharge frame 41 is just the height of the through cavity 43a. The two sides of the connecting arm 44 are provided with a slot 50 at a distance away from the connecting rod 43 and less than half the length of the connecting arm 44. The slot 50 is slidably connected to the support frame 51. Figure 4As shown. And the bottom of the support frame 51 is fixedly connected to the bottom of the blanking frame 41. In this embodiment, when the previous screw enters the through cavity 43a, the next screw will continue to be released from the clamping column 36 and fall into the receiving plate 45. After the receiving plate 45 is hit by the screw, the receiving plate 45 will be subjected to a downward impact force, thereby cooperating with the action of the connecting arms 44 on both sides, and will rotate with the support frame 51 as the fulcrum, thereby changing the height of the through cavity 43a. When the height of the through cavity 43a is greater than the diameter of the screw head, the wheel screw will keep the head up and the tail down and slide down from the blanking frame 41. In summary, the present device can achieve the effect of fully automatic arrangement and collection of screws, and can cooperate with the assembly inspection machine to achieve the effect of material collection without the need for an additional power mechanism.

[0041] In order to better utilize the receiving plate 45 to receive the screw, the contact surface of the receiving plate 45 is configured as an arc structure with a certain curvature. The upward curved surface has a certain deceleration effect. When the receiving plate 45 receives the screw, the screw will first generate a downward impact force on the receiving plate 45. Under the action of the curved structure, the screw will be decelerated, thus preventing the screw from falling too quickly and flying off the receiving plate 45 at the moment of contact with the receiving plate 45.

[0042] like Figure 5 and Figure 6 、 Figure 7 As shown, a pushing mechanism 60 is provided at the rear of the blanking frame 41, and the pushing mechanism 60 includes a tooth plate 61 fixedly connected to the connecting rod 43. The tooth plate 61 is designed to be tilted upward, and a groove cavity is opened at the top of the blanking frame 41. The interior of the groove cavity is rotatably connected to a rotating gear 62 through a connecting shaft. The tooth plate 61 is meshed when in contact with the rotating gear 62, as shown in FIG. Figure 9 When the current screw passes through the through cavity 41a under the action of the next screw, it will come to the rear of the blanking frame 41, that is, the flat area. Compared with the inclined surface in front of the blanking frame 41, the flat area is relatively fast for the blanking of the screws.

[0043] When the third set of screws is about to enter the blanking assembly 40, the screws will have two states in the blanking frame: one is that the previous screw reaches the flat area, and the other is that the next screw is confined to the through cavity 41a. When the third set of screws contacts the receiving plate 45, the above action will be repeated, and the connecting rod 43 will move upward, cooperating with the toothed plate 61 to move upward synchronously. This will drive the rotating gear 62 to rotate. During the rotation process, the rotating gear 62 will drive the fixed rods 63 on both sides to deflect, and the bottom of the fixed rods 63 is fixedly installed with a material removal rod 64. When the fixed rod 63 deflects, it will simultaneously drive the material removal rod 64 to approach the bottom of the flat area of ​​the blanking frame 41, thereby moving the previous screw out of the flat area and into the collection box.

[0044] The interior of the collection box is distributed in a disc shape, such as Figure 10 As shown, under the action of the material-moving rod 64, the screws can be pushed into the disc of the collection box in the previous state. After a group (i.e., two) of screws are pushed into the disc of the collection box, the disc advances under the action of the driving mechanism, and the distance of the advance is equal to the distance the next group of screws are pushed into the disc. By following the above sequence, the screws can be evenly arranged one by one. In this process, it is worth noting that the material-moving rod 64 pushes the screws to move, and it still maintains the previous state to move. Finally, the wheel screws are arranged in the same order with the screw heads on top and the tails on the bottom.
