[0031] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1 As shown, the auxiliary loading tooling for the core rib of an automobile seat of the present invention comprises a carrier plate 1, a first guide member 2, a second guide member 3 and a limit member 4.

[0033] like Figure 3As shown in the figure, the core rib corresponding to the present tool is recorded, and the core rib includes a bending portion, and hook portions arranged at both ends of the bending portion, two U-shaped sections are arranged on the bending portion, one of the two hook portions is U-shaped, and the other is C-shaped, and the bending portion and the two hook portions are not in a straight line. In addition to the core rib shown in the figure, it is not ruled out that there are other core ribs with similar structures that can use this tool for auxiliary loading.

[0034] The extension line of the carrier plate 1 intersects with the horizontal plane to form an acute angle. The carrier plate 1 is a plate-shaped component, and its length direction is the extension direction of the extension line of the carrier plate 1. The carrier plate 1 is the main bearing structure of the tooling and needs to have a certain rigidity to carry multiple arranged core ribs.

[0035] There are two first guide members 2, which are parallel to each other and fixed relatively to the carrier plate 1. A movable gap is provided between the first guide member 2 and the carrier plate 1. The first guide member 2 is used to guide the hook portion of the core rib, and the movable gap is used for the hook portion of the core rib to slide between the first guide member 2 and the carrier plate 1.

[0036] Specifically, the first guide member 2 is a long strip member, and two symmetrical first guide members 2 are used to limit the two hook parts of the core rib. Before the hook part moves, it needs to pass through the movable gap and penetrate from one side of the first guide member 2 to the other side. That is to say, the hook part passes through the bottom of the first guide member 2 and is arranged on the outside of the first guide member 2 in a semi-sleeved form, so that the hook part of the core rib will not be skewed during the sliding process. At the same time, in order to avoid the first guide member 2 hindering the sliding of the hook part of the core rib, the first guide member 2 only contacts the hook part of the core rib during the sliding process of the core rib. After the core rib is in place, its two hook parts do not contact the first guide member 2. That is to say, when the core rib slides, the first guide member 2 will not pull or squeeze the core rib to avoid the hook part of the core rib being stuck on the first guide member 2. In addition, in order to reduce the friction resistance between the core rib and the first guide member 2, the contact part of the first guide member 2 and the core rib can be polished or other treatments.

[0037] The second guide member 3 is fixed on the carrier plate 1. The second guide member 3 is located between the two first guide members 2 and is parallel to the first guide members 2. The second guide member 3 is used to guide the bending portion of the core rib so that the core rib slides to the material picking end of the second guide member 3 under the action of the gravity component force. The material picking end is the end of the second guide member 3 close to the ground.

[0038] Specifically, in the present embodiment, two U-shaped sections are arranged on the bending part of the core rib, and between the two U-shaped sections, there is also a connecting section, which has a U-shaped groove, and the U-shaped groove can be buckled on the second guide member 3, and the hook part and the bending part of the core rib are respectively limited and guided by two first guide members 2 and one second guide member 3. During the movement, the core rib contacts the guide members through three parts to perform posture correction, thereby limiting its sliding direction and posture after stopping, so that subsequent equipment can accurately locate and grasp it.

[0039] The limiting member 4 is fixed on one end of the carrier plate 1 close to the horizontal plane, and is used to prevent the core rib on the material taking end of the second guide member 3 from leaving the second guide member 3 under the action of the gravity component force.

[0040] The limiter 4 is fixed at the top of the bottom end of the carrier plate 1, which can prevent the core bars on the three guide members from continuing to slide under the action of the gravity component force. After the limiter 4 contacts the core bar on the feeding end of the second guide member 3, it can prevent the core bar from continuing to slide. At the same time, the core bars arranged behind the core bar will be blocked from continuing to slide. Only after the core bar on the feeding end of the second guide member 3 is taken away, a feeding gap is formed. The arranged core bars can fill the feeding gap by sliding, and this cycle is repeated. The core bars will be continuously replenished after feeding until all the core bars on the carrier plate 1 are taken away.

[0041] In this embodiment, the core rib removed from the carrier plate can be directly installed on the seat frame without manual pre-installation for subsequent removal by the robotic arm.

[0042] As a preferred embodiment, the limit member 4 is arranged in a V shape and has a limit surface, which intersects with the horizontal plane to form an acute angle. The limit surface is used to contact the core rib at the material picking end of the second guide member 3 and prevent the core rib from leaving the second guide member 3 under the action of the gravity component.

[0043] The side of the limit member 4 facing the core rib is a limit surface for contacting the core rib, and the other side is a mounting surface, on which a waist-shaped hole is provided. The limit member 4 can be fixed on the carrier plate 1 through bolts and the waist-shaped hole, and the limit member 4 can be adjusted according to the structural characteristics of the core rib, so that when the limit member contacts the core rib, the position of the core rib can be corrected through the limit surface, so that it can be fully adjusted to the posture required for the equipment to grasp.

[0044] In this embodiment, since two U-shaped sections are provided on the bending portion of the core rib, correspondingly, the number of the limiting members 4 is two, and they are respectively located on both sides of the material picking end of the second guide member 3. When the core rib contacts the limiting surfaces of the two limiting members 4, the two hook portions of the core rib leave the first guide member 2. After the core rib at the material picking end of the second guide member 3 is in place, the two U-shaped sections will respectively contact the two limiting members 4, and limit the three parts in combination with the second guide member 3, thereby effectively adjusting the posture of the core rib. At the same time, since the hook portion of the core rib leaves the first guide member 2 after being in place, the grasping device can directly grasp the core rib from the side of the core rib, and remove the core rib from the carrier plate 1 along the limiting surface on the limiting member 4, to avoid the first guide member 2 obstructing the core rib.

[0045] In addition, in the present embodiment, two fixing components 5 are provided, and both of the two fixing components 5 are fixed on the carrier plate 1 and are mirror images of each other. The two first guide members 2 are respectively fixed on the two fixing components 5. The two first guide members 2 are fixed to the carrier plate 1 by the two fixing components 5, and a movable gap is left at the same time to avoid contact with the core rib during the sliding process of the core rib.

[0046] Specifically, the fixing assembly 5 includes a vertical plate 51 and a connecting member 52. The vertical plate 51 is fixed on the carrier plate 1. There are multiple connecting members 52, and they are all fixed on the side of the vertical plate 51 facing the first guide member 2. The multiple connecting members 52 are arranged along the length direction of the first guide member 2 and are all fixed to the first guide member 2. The connecting member 52 is L-shaped, and the two ends are respectively fixed to the vertical plate 51 and the first guide member 2, specifically to the top of the first guide member 2, so that the outside of the first guide member 2 can be covered with a hook part, and the hook part can be moved. Since the hook part is a non-closed loop shape, the connecting member 52 is located on the open side when the hook part slides, thereby not hindering the sliding of the hook part.

[0047] As a preferred embodiment, the acute angle formed by the intersection of the extension line of the carrier plate 1 and the horizontal plane is 10°-30°. When the acute angle formed by the intersection of the extension line of the carrier plate 1 and the horizontal plane is less than 10°, the gravity component may be equal to the static friction force of the core rib, resulting in the core rib being unable to slide under the action of the gravity component. On the contrary, when the acute angle formed by the intersection of the extension line of the carrier plate 1 and the horizontal plane is greater than 30°, the gravity component of the core rib will be too large. During the sliding process of multiple core ribs, strong mechanical collisions may occur, resulting in core rib dislocation or skewness of the bottom core rib, affecting the normal material picking action of the grasping device. Therefore, the acute angle formed by the intersection of the extension line of the carrier plate 1 and the horizontal plane is preferably about 20°.

[0048] In order to further reduce the friction resistance between the core rib and the tooling and improve the sliding stability of the core rib, a chamfered surface is provided on the side of the second guide member 3 away from the carrier plate 1, and a curved surface is provided on the side of the first guide member 2 facing the movable gap. The chamfered surface and the curved surface are respectively used to contact the bending portion and the hook portion of the core rib. By providing the chamfered surface and the curved surface, unstable direct contact between the corner and the core rib is avoided. By contacting the core rib with the curved surface, the friction threshold of the core rib converted from static friction to dynamic friction can be reduced, thereby improving the sliding smoothness.

[0049] like Figure 2 As shown, the automobile seat core rib auxiliary feeding device of the utility model comprises a plurality of the above-mentioned automobile seat core rib auxiliary feeding tools, and the plurality of the automobile seat core rib auxiliary feeding tools are relatively fixed.

[0050] By arranging a plurality of feeding tools on the feeding device, a core bar storage warehouse can be formed, thereby arranging more core bar stocks per unit volume and extending the feeding cycle.

[0051] As a preferred embodiment, the extension lines of the carrier plates 1 of the plurality of auxiliary feeding tools for the core ribs of the automobile seat are parallel to each other, and the feeding ends of the second guide members 3 are all located in the same vertical plane to form the feeding end of the auxiliary feeding device, and the feeding end is used for the feeding equipment to grab the core ribs. The ends of the plurality of carrier plates 1 away from the feeding end are all located in the same vertical plane to form the feeding end of the auxiliary feeding device, and the feeding end is used to supplement the core ribs to the feeding device. This arrangement allows the feeding equipment to perform feeding operations from one side of the feeding device. It only needs to set the coordinates of the feeding ends of each feeding tool to perform feeding in sequence. The other side serves as the feeding end of the feeding device, and the core ribs can be supplemented manually or by other means, so that the feeding and feeding do not affect each other, thereby achieving uninterrupted feeding action of the equipment to improve the seat production efficiency.

[0052] In this embodiment, in order to fix multiple auxiliary loading tools together, a fixing frame 10 is also provided, and multiple auxiliary loading tools for automobile seat core bars are fixed on the fixing frame 10 and arranged in an array. By fixing multiple auxiliary loading tools for automobile seat core bars on the fixing frame 10 and arranging them in an array, the material picking device can take away at least two core bars at the same time in one material picking action, thereby improving the efficiency of taking the core bars.

[0053] In addition, the material picking equipment can pick up two core bars at a time by setting four hooks, with two hooks corresponding to one core bar. For one core bar, the two hooks grab the core bar by grabbing the bent part of the core bar. A pneumatic active end is set on the hook, and the bent part of the core bar is pressed tightly against the hook by pneumatic means, thereby realizing material picking and preventing the core bar from changing its relative posture and falling during the material picking process.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
