Description

Technical Field

[0001] The utility model relates to the technical field of seal strip processing, in particular to a rubber seal strip flipping and blanking device. Background Art

[0002] The rubber seal strip for automobiles is generally flat. During the assembly production process, it needs to go through processes such as extrusion molding, cutting, dotting, flaring, and inspection in sequence before assembly work can be carried out. In some processes, extrusion molding may be carried out by upstream manufacturers, and the actual assembly manufacturers directly purchase the rolled seal strips for direct cutting and use. Currently, after the rubber seal strip is flared by the assembly manufacturer, the rubber seal strip needs to be flipped, that is, turned over, which is beneficial for the later assembly equipment to directly pick up and assemble, improving work efficiency.

[0003] Currently, the commonly used equipment for flipping rubber seal strips generally adopts the method of directly driving the rubber seal strip to rotate around its own length direction. For example, mechanical claws are used to grasp the whole rubber seal strip and rotate it around an axis parallel to the length direction of the rubber seal strip, so as to achieve flipping. Such a rotation method is simple and convenient. However, since the rubber seal strip is relatively long as a whole, if it is flipped around its own length direction, it needs to overcome its own deflection, and at the same time, it is necessary to clamp the whole rubber seal strip or most of the areas of the rubber seal strip for flipping, and at the same time, it is necessary to avoid local torsion of the rubber seal strip. Therefore, such a flipping method is difficult to ensure the quality of flipping. Moreover, with the increasing degree of automation, generally a separate manipulator is configured to perform blanking processing on the flipped rubber seal strip. These manipulators are generally integrated structures, so the overall volume of the equipment is relatively large, and the connection between the manipulator and the flipping equipment is not coherent enough, and the overall efficiency is restricted. Therefore, a device integrating flipping and blanking is needed to complete the process of flipping and blanking transfer of the rubber seal strip. Content of the Utility Model

[0013] In some possible implementation manners, each receiving assembly includes a rotating cylinder and a limiting member arranged on the outer wall of the outer end of the rotating cylinder.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present disclosure, unless otherwise stated, the meaning of "a plurality" is two or more.

[0025] Referring to Figures 1 to 4 A rubber sealing strip flipping and discharging device as shown, including a frame 100, a positioning mechanism 200, a flipping mechanism 300, a receiving and discharging assembly 400, and a discharging manipulator 500; the positioning mechanism 200 is installed on the frame 100 and is used to receive and position the rubber sealing strip; the flipping mechanism 300 is installed on the frame 100 and is used to clamp and drive the rubber sealing strip in the positioning mechanism 200 to turn over; the receiving and discharging assembly 400 is installed on the frame 100 and is used to receive the rubber sealing strip after flipping output by the flipping mechanism 300; the discharging manipulator 500 is installed on the frame 100 and is used to clamp and transfer the rubber sealing strip output by the receiving and discharging assembly 400.

[0026] In this application, the flipping mechanism 300 can adopt a traditional flipping method and can adopt a rotating method perpendicular to the length direction of the rubber sealing strip for flipping. The discharging manipulator 500 in this application can be a common multi-axis manipulator. In the accompanying drawings of this application, the structure where the discharging manipulator 500 is directly connected to the frame 100 is not drawn. Omitting this structure is beneficial to seeing other structures clearly.

[0027] The rubber sealing strip flipping and unloading device of the utility model adopts a positioning mechanism 200 to receive and position the rubber sealing strip, which is conducive to the flipping mechanism 300 to clamp and drive the rubber sealing strip to flip, thereby ensuring the quality of flipping. The receiving and unloading component 400 is used to receive the rubber sealing strip output by the flipping mechanism 300 after flipping, thereby ensuring that the unloading manipulator 500 can accurately clamp the rubber sealing strip after flipping for transfer. In addition, the design of the receiving and unloading component 400 can ensure that the unloading manipulator 500 has sufficient installation space to clamp the rubber sealing strip, while reducing the motion interference between the unloading manipulator 500 and the flipping mechanism 300, thereby ensuring the quality of clamping.

[0028] See also Figures 1 to 4 In order to facilitate the working end of the flipping mechanism 300 to effectively clamp the rubber sealing strip, the positioning mechanism 200 includes a base 210 and limiting guide plates 220 arranged on both sides of the base 210. The base 210 is installed on the frame 100 below the flipping mechanism 300. The area between the two limiting guide plates 220 forms a feeding channel 230. The base 210 is located at the end of the feeding channel 230 and a limiting plate 240 is arranged. The base 210 is located at the end of the feeding channel 230 to form a clamping station. The working end of the flipping mechanism 300 can clamp the end of the rubber sealing strip in the clamping station.

[0029] Among them, in the above-mentioned embodiment, one end of the two limiting guide plates 220 for feeding is provided with a tip that bends outwards, and cooperates with each other to form a bell mouth, which is conducive to the expansion device to convey the rubber sealing strip into the feeding channel 230. In addition, in some embodiments, a positioning plate is provided on one end of the feeding channel 230 located at the clamping station, which is conducive to the accurate clamping of the working end of the flip mechanism 300.

[0030] See also Figures 1 to 3In order to better turn over the rubber sealing strip and ensure the quality of turning over, the turning mechanism 300 includes a turning motor 310, a plurality of large sprockets 320, and a turning chain 330 wound around all the large sprockets 320. All the large sprockets 320 are rotatably mounted on the frame 100. The turning motor 310 is mounted on the frame 100 and connected to any large sprocket 320. The turning chain 330 is provided with a clamping gripper 340. The clamping gripper 340 can clamp the rubber sealing strip in the positioning mechanism 200. The receiving and unloading assembly 400 is arranged below the top of the turning chain 330. The receiving and unloading assembly 400 can receive and support the rubber sealing strip clamped by the clamping gripper 340. The turning chain 330 as a whole forms an annular structure, which is conducive to realizing the cyclic clamping of the rubber sealing strip in the feeding channel 230. It should be noted that in the improved scheme of the above embodiment, the flip chain 330 drives the clamping gripper 340 to move to the top of the clamping station, and then the clamping gripper 340 extends to clamp the rubber sealing strip in the clamping station, so as to clamp the end of the entire rubber sealing strip. In this way, under the rotation of the flip chain 330, the clamping gripper 340 can drive the entire rubber sealing strip to rotate around its rotation center following the flip chain 330. Since the clamping station in this application is located at the bottom, and the receiving and unloading assembly 400 is arranged below the top of the flip chain 330, when the flip chain 330 drives the clamping gripper 340 and the rubber sealing strip to move to the top of the receiving and unloading assembly 400, the end of the rubber sealing strip has been turned over, and as the flip chain 330 continues to move, the entire rubber sealing strip is finally turned over.

[0031] In some possible implementations, to facilitate the grasping of the rubber sealing strip and the subsequent turning and blanking, the turning chain 330 that rotates around all the large sprockets 320 has at least one bottom flat section 331 and a pair of top flat sections 332. The receiving and blanking assembly 400 is arranged on the frame 100 below the top flat section 332, and the positioning mechanism 200 is arranged on the frame 100 below the bottom flat section 331. Such an arrangement is beneficial for the clamping gripper 340 to move to the clamping station and for the receiving and blanking assembly 400 to receive the turned rubber sealing strip. Among them, the length of the top flat section 332 is less than the length of the rubber sealing strip. Such a design can reduce the size of the entire device, and at the same time, appropriately allow the two ends of the rubber sealing strip to droop naturally and the middle part to be received by the receiving and blanking assembly 400, which can ensure the placement stability of the rubber sealing strip on the receiving and blanking assembly 400. In fact, during the actual operation of this application, the rubber sealing strip is driven by the turning chain 330 to bypass the receiving and blanking assembly 400, and then the middle part of the rubber sealing strip is received by the receiving and blanking assembly 400. After the clamping gripper 340 moves to the set position following the turning chain 330, it will automatically release the clamped rubber sealing strip, and then the turning chain 330 continues to rotate into the next turning cycle.

[0032] See Figure 3 and Figure 4 In order to facilitate the receiving and blanking assembly 400 to effectively receive the rubber sealing strip driven by the clamping gripper 340 and at the same time to be able to convey the rubber sealing strip outwards to the working area of the blanking manipulator 500, the receiving and blanking assembly 400 includes a pair of receiving assemblies 410 and a conveying assembly 420. The conveying assembly 420 is arranged on the frame 100 in the area below the top of the turning chain 330, and a pair of receiving assemblies 410 are arranged on the frame 100 in the corresponding areas on both sides of the conveying assembly 420. The pair of receiving assemblies 410 can jointly receive the middle area of the rubber sealing strip driven by the clamping gripper 340, and then lower the rubber sealing strip to the input end of the conveying assembly 420. The conveying assembly 420 can drive the rubber sealing strip to be conveyed to the working area of the blanking manipulator 500. Among them, in this embodiment, the main purpose of the receiving assembly 410 is to receive the rubber sealing strip running to the top and at the same time to avoid the situation where the rubber sealing strip droops automatically. In fact, the receiving assembly 410 provides a support point to support the middle part of the turned rubber sealing strip. The design of the pair of receiving assemblies 410 can ensure that the rubber sealing strip can be stably received. The conveying assembly 420 can be a traditional conveyor belt or a clamping structure in this embodiment.

[0033] In order to better receive the rubber seal strip and facilitate the rubber seal strip to move along with the operation of the flip chain 330, each receiving assembly 410 includes a rotating drum 411 and a limiting member 412 arranged on the outer wall of the outer end of the rotating drum 411. The inner ends of the two rotating drums 411 can be rotatably mounted on the frame 100. The rotating drum 411 can receive the rubber seal strip on the clamping gripper 340. The rotating drum 411 drives the limiting member 412 to rotate around the rotation center of the rotating drum 411. The input end of the conveying assembly 420 can hook or take away the rubber seal strip between the two rotating drums 411. When the rubber seal strip moves to the first rotating drum 411 following the flip chain 330, the rubber seal strip begins to turn along one end of the movement direction, and its tail naturally droops due to its own weight; as the flip chain 330 continues to move in the top plane section 332, the drooping part naturally bypasses the first rotating drum 411 and turns into the horizontal section until it enters the working area of the second rotating drum 411. When the flip chain 330 continues to rotate, it will gradually change from the top plane section 332 to downward movement. At this time, the end of the rubber sealing strip will also move downward and begin to bypass the rotating drum 411 until it follows the clamping clamp 340 to move to the preset position and is released by the clamping clamp 340. At this time, both ends of the rubber sealing strip bypass the two rotating drums 411 respectively and droop naturally, while the middle area is jointly supported by the two rotating drums 411, which is conducive to being received by the conveying component 420.

[0034] See also Figure 3 and Figure 4 In order to improve the quality and stability of conveying, the conveying assembly 420 includes a mounting frame 421, a plurality of small sprockets 422 rotatably arranged on the mounting frame 421, and a conveying chain 423 wound around all the small sprockets 422, a plurality of load-bearing hooks 424 are arranged on the conveying chain 423, and a conveying motor for driving any small sprocket 422 to rotate is arranged on the mounting frame 421. The mounting frame 421 is arranged on the area where the frame 100 is located below the top of the flip chain 330.

[0035] Among them, since the middle of the rubber sealing strip is between the two rotating drums 411, and the conveying chain 423 is located between the two rotating drums 411, the middle of the rubber sealing strip can be hooked by the load-bearing hook 424, and it will not slide down from any side. It should be noted that in this application, in order to improve the stability of transportation, the small sprockets 422 are respectively arranged on both sides of the mounting frame 421, and all the small sprockets 422 on each side are individually wrapped by a conveying chain 423, so that the width of the mounting frame 421 is used to improve the stability of transportation and prevent the rubber sealing strip from sliding down from one side.

[0036] In some possible implementations, in order to facilitate receiving the rubber sealing strip conveyed by the conveying chain 423, the mounting frame 421 is provided with a receiving bracket 425 at the end of the conveying chain 423, and a plurality of rollers 426 arranged in a straight line are arranged on the receiving bracket 425. Two parallel receiving support rods 427 are arranged below the roller 426 at the bottom of the receiving bracket 425, and the two receiving support rods 427 can jointly support the rubber sealing strip, and the unloading robot 500 can clamp the rubber sealing strips on the two receiving support rods 427. In fact, a slope is provided on the outward side of the mounting frame 421, so that the conveying chain 423 can drive the rubber sealing strip to move outward and forward, so that the height of the rubber sealing strip can be reduced and adapted to the working end of the unloading robot 500. The main reason is that during the actual installation process, the unloading robot 500 is installed on the top of the frame 100, and the top plane section 332 is close to the top of the frame 100. At this time, there is not enough movement space for the unloading robot 500 to move, so it is necessary to reduce the height of the rubber sealing strip. The top plane section 332 is set at the top of the frame 100 mainly to adapt to the length of the rubber sealing strip to prevent the two ends of the rubber sealing strip from hanging down to the ground when being transported by the conveying chain 423, thereby affecting the normal assembly work.

[0037] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto.
