Description

Technical Field

[0001] This invention relates to the field of clamp structure technology, specifically to a natural rubber block peeling clamp and its rubber removal method. Background Technology

[0002] In the natural rubber processing production line, the rubber material, after coagulation, sheeting, and granulation, needs to be sent to a tunnel-type hot air penetration drying oven for drying. The rubber material is loaded on a drying cart, which consists of a base plate with rollers and a detachable feeding frame. The base plate has a porous mesh structure to facilitate hot air penetration and baking. The feeding frame divides the base plate into several storage compartments, each for holding the rubber material. After drying and shaping, several rubber blocks weighing approximately 10-20 kg are obtained. Because the drying cart's base plate has a porous mesh structure, some of the rubber material softened by heat during the drying process embeds into the mesh. After drying, the two interlock. Simultaneously, natural rubber itself has adhesiveness and elasticity, forming a strong interfacial bond after extensive contact with the drying cart's base plate. Based on these two points, a significant adhesion effect occurs between the bottom surface of the rubber block and the drying cart's base plate. Tests have shown that the maximum pull-out force required to remove a single rubber block from the drying cart can exceed 588 N.

[0003] After drying, the drying cart exits from the furnace opening. The rubber blocks need to be removed from the drying cart's floor and transferred for subsequent processes such as weighing and packaging. This unloading process is a necessary node between the drying line and the packaging line, but it generally suffers from the following problems: First, the rubber removal process generally involves manual peeling. Specifically, workers manually lift each rubber block from the side, using that position as the starting point for peeling, and gradually tear the rubber block off the drying truck floor until it is completely removed. This method requires overcoming the adhesion between the bottom of the rubber block and the drying truck floor, then bearing the weight of the rubber block, and transporting it to the conveyor equipment. This results in high labor intensity, low efficiency, and high labor costs. Second, although anti-stick coatings or insulating mats can be applied to the drying truck floor to reduce the adhesion between the bottom of the rubber block and the drying truck floor, the durability of anti-stick coatings is insufficient, requiring re-coating for each vehicle and each round. Insulating mats increase the consumption of auxiliary materials and replacement processes, both of which generate high ongoing costs.

[0004] Secondly, regarding the structure of natural rubber blocks, the formed rubber blocks are made of loosely stacked particles dried by hot air penetration. The overall structure is a two-layer structure: the upper layer is a loosely aggregated layer with high porosity, and the lower layer is a dense, continuous, and high-strength rubber layer. Based on these structural characteristics of natural rubber blocks, if conventional unloading jigs are used to vertically remove the rubber blocks from the drying truck floor, the following issues will arise: 1. For example, a pin-type clamp is used, in which multiple pins are vertically inserted into a molded rubber block, and then the pins are driven to deflect inside the rubber block to clamp the rubber block and pull it out of the drying cart. However, the overall tensile strength of the rubber block is low, and the loose upper structure is particularly unable to withstand concentrated loads, which can easily lead to the upper structure being torn apart. The pins detach directly from the rubber block, and the actual pulling force cannot be effectively applied to the entire rubber block. In the end, the rubber block is in a broken state and still adheres to the bottom plate of the drying cart, increasing the additional rubber block cleaning work.

[0005] 2. For example, a plate-type friction clamp is used, which clamps multiple plates simultaneously around the sides of the rubber block. Each plate has an anti-slip pad on its inner side. The friction is used to lift the rubber block and remove it from the drying cart. However, the friction coefficient of the rubber block surface is limited, and the upper structure is loose and easily deformed. The actual friction force is sometimes insufficient to overcome the bottom adhesion force, causing the rubber block to slip frequently. Repeated clamping and gripping are required, resulting in low actual rubber removal efficiency and easy damage to the rubber block. Summary of the Invention

[0006] The purpose of this invention is to provide a natural rubber block peeling clamp and a rubber removal method thereof, which can simulate the action of manually tearing rubber and quickly and completely peel the rubber block from the dry vehicle floor, greatly reducing the cost of rubber removal.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a natural rubber block peeling clamp, comprising: The movable frame assembly includes a frame unit and a first drive unit. The first drive unit is disposed on the frame unit and is used to drive the frame unit to change between a first state and a second state. When the frame unit is in the first state, both ends of the frame unit extend in the left and right directions so that the bottom surface of the frame unit forms a horizontal plane. When the frame unit is in the second state, both ends of the frame unit bend upward so that the bottom surface of the frame unit forms a convex arc surface. The movable gripper assembly includes a second drive unit and two gripper assemblies. The two gripper assemblies are respectively hinged to both ends of the frame unit. The second drive unit is disposed on the frame unit and is used to drive the two gripper assemblies to open or clamp.

[0008] Furthermore, the frame unit includes a main frame and multiple sub-supports. The multiple sub-supports are symmetrically arranged on both sides of the main frame with the main frame as the center. There is a gap between adjacent main frames and sub-supports, and between every two adjacent sub-supports, and they are connected to each other by a first hinge.

[0009] Furthermore, the first drive unit is provided with two components, each including a first hydraulic cylinder, a second hinge, and a first sleeve. The two first hydraulic cylinders are respectively mounted on both sides of the main frame via the second hinge, and the output ends of the two first hydraulic cylinders are respectively hinged to the two outermost sub-supports via the first sleeve.

[0010] Furthermore, the two first drive units are configured to be staggered in the lateral direction.

[0011] Furthermore, the gripper assembly includes a hinge rod, a fixed rod, and multiple hooks. One end of each hook is hinged to the end of the frame unit via the hinge rod, and the other end of each hook has a pointed structure. The hooks are arranged parallel to each other and spaced apart along the axis of the hinge rod. The fixed rod is mounted on the hook and is parallel to the hinge rod. The second drive unit has two components, each including a second hydraulic cylinder and a second sleeve. The two second hydraulic cylinders are located at both ends of the frame unit, and the output ends of the two second hydraulic cylinders are hinged to the two fixed rods via the second sleeves.

[0012] Furthermore, the two second drive units are configured to be staggered in the lateral direction.

[0013] Furthermore, it also includes a connection structure for interconnecting with the robotic arm, the connection structure being located at the top center of the frame unit.

[0014] Furthermore, it also includes a connection structure for interconnecting with the robotic arm. The natural rubber block peeling clamps are provided in two and arranged side by side in the front-rear direction. The connection structure is located at the center top between the two frame units and fixes the two natural rubber block peeling clamps together.

[0015] Furthermore, the connection structure is a flange.

[0016] The present invention also provides a method for removing rubber, wherein the method uses the aforementioned natural rubber block peeling clamp and includes the following steps: Step 1: Install the natural rubber block peeling clamp at the end of the robotic arm; Step 2: For the rubber block adhering to the drying cart, the robotic arm is used to move the natural rubber block peeling clamp, while the first drive unit drives the frame unit to change to the first state, so that the bottom surface of the frame unit abuts against the upper surface of the rubber block. Step 3: The second drive unit drives the two gripper assemblies to perform a gripping action and inserts them into the bottom positions on both sides of the rubber block; Step 4: The first drive unit drives the frame unit to change to the second state. The two ends of the frame unit drive the two sides of the rubber block to be gradually lifted through two gripper assemblies. At the same time, the rubber block is gradually separated from the drying cart along the opposing path from the bottom edge of its two sides to the bottom center, until the two ends of the frame unit bend upward and extend to the limit position. Step 5: Use the robotic arm to lift the natural rubber block peeling fixture so that the rubber block is completely removed from the drying cart. Then move the rubber block to the waiting station. The second drive unit drives the two gripper assemblies to perform an opening action and place the rubber block in the waiting station. Step Six: After completing one rubber block peeling operation, return to Step Two until all rubber blocks are transferred from the drying cart to the waiting station.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This fixture requires a robotic arm for movement and positioning. The fixture inserts two gripper assemblies into the bottom edges of the rubber block from both sides, hooking onto the dense and compact lower structure of the rubber block while avoiding the loose and easily deformable upper structure. This ensures that the force is stably transmitted to the bottom sides of the rubber block. As the frame unit changes from the first state to the second state, the two gripper assemblies gradually lift the sides of the rubber block, causing the adhesive surface of the rubber block to be peeled off from the sides towards the center. Finally, the entire rubber block is peeled off the dry car floor, achieving automated mechanical degumming, reducing the labor intensity of workers, greatly improving degumming efficiency, and significantly reducing degumming costs.

[0018] 2. Unlike existing methods of vertically pulling off rubber blocks, this clamp simulates manual tearing action for rubber blocks that are adhered to a large area on the dry vehicle floor. The actual force required to peel off the rubber block is much less than the force required to vertically pull off the rubber block, achieving low-resistance unloading and greatly improving the stability of unloading.

[0019] 3. For the removal of rubber blocks using this clamp, since the two gripper assemblies only hook onto the dense and compact lower structure, the force application point is located in the lower structure with strong load-bearing capacity, while the loose upper structure is only deformed by pressure. This not only enables stable gripping and tearing of the rubber block, but also ensures that the removed rubber block is not damaged excessively, thus maintaining the integrity of the original shape of the rubber block.

[0020] 4. Because the drying vehicle floor plate is a deformable porous mesh structure, compared with the existing method of vertically pulling out rubber blocks, this clamp will not cause excessive bending deformation to the drying vehicle floor plate when tearing off the rubber blocks. It has better adaptability and fault tolerance to the deformation of the drying vehicle floor plate, thus extending the service life of the drying vehicle floor plate.

[0021] 5. This fixture has a simple overall structure and requires fewer parts. It can be quickly maintained and replaced on-site and is suitable for high-intensity processing and production environments. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Rather, the use of the words "for example" or "for instance" is intended to present the relevant concepts in a specific manner.

[0030] In the description of the embodiments of this application, the term "multiple" means two or more. For example, multiple systems means two or more systems, and multiple screen terminals means two or more screen terminals. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. The terms "comprising," "including," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0031] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the present invention provides a natural rubber block peeling clamp, comprising: The movable frame assembly includes a frame unit 1 and a first drive unit 2. The first drive unit 2 is disposed on the frame unit 1 and is used to drive the frame unit 1 to change between a first state and a second state. When the frame unit 1 is in the first state, the two ends of the frame unit 1 extend in the left and right direction so that the bottom surface of the frame unit 1 forms a horizontal plane. When the frame unit 1 is in the second state, the two ends of the frame unit 1 bend upward so that the bottom surface of the frame unit 1 forms a convex arc surface. The movable gripper assembly includes a second drive unit 3 and two gripper assemblies 4. The two gripper assemblies 4 are respectively hinged to both ends of the frame unit 1. The second drive unit 3 is disposed on the frame unit 1 and is used to drive the two gripper assemblies 4 to open or clamp.

[0032] In this embodiment, for the actual use of this clamp, it needs to be assembled at the end of a robotic arm. The robotic arm is used to move the clamp so that it can position, align, and transport the rubber block 6 to be removed from the drying truck floor. The working process of this clamp is as follows: For the rubber block 6 that is adhered to the drying truck floor over a large area, the first drive unit 2 drives the frame unit 1 to the first state. With the movement control of the robotic arm, the bottom surface of the frame unit 1 is made to fit against the upper surface of the rubber block 6. Then, the second drive unit 3 drives the two gripper assemblies 4 to perform a clamping action, so that the two gripper assemblies 4 are inserted from the bottom edges on both sides of the rubber block 6, thereby hooking the rubber block 6. The dense lower structure avoids the loose and easily deformable upper structure, ensuring that the force can be stably transmitted to the bottom sides of the rubber block 6. Then, the first drive unit 2 drives the frame unit 1 to change to the second state, with the two ends of the frame unit 1 bending and extending upwards. The two gripper assemblies 4 drive the two sides of the rubber block 6 to gradually lift, so that the adhesive surface of the rubber block 6 is torn off from the two sides to the center until the two ends of the frame unit 1 bend and extend upwards to the limit. At this time, the adhesive area between the bottom surface of the rubber block 6 and the bottom plate of the drying cart is minimized. Then, through the lifting process of the robotic arm, the entire rubber block 6 can be easily peeled off the bottom plate of the drying cart, realizing automated mechanical unloading.

[0033] It should be understood that for the rubber block 6 that is adhered to a large area on the dry vehicle floor, this clamp simulates the action of manually tearing the rubber. Compared with the existing vertical pulling of the rubber block 6, the force required to actually peel off the rubber block 6 is much less than the force required to vertically pull the rubber block 6, so as to achieve low-resistance unloading of the rubber block 6. This not only effectively improves the unloading efficiency, but also greatly improves the stability of unloading and the success rate of rubber removal.

[0034] It is important to understand that, in the process of removing the rubber block 6, since the two gripper assemblies 4 hook onto the dense and compact lower structure, the point of force is located in the lower structure with strong load-bearing capacity. The loose upper structure is deformed by the clamping action. This not only enables a stable clamping and tearing action for the rubber block 6, but also prevents the rubber block 6 from easily detaching from the clamp during the tearing process. Furthermore, it ensures that the removed rubber block 6 is not damaged excessively, thus maintaining the integrity of the original shape of the rubber block 6.

[0035] It should be noted that, since the floor of the drying vehicle is a deformable porous mesh structure, compared with the existing vertically pulled rubber block 6, this clamp will not cause excessive bending deformation to the floor of the drying vehicle when tearing off the rubber block 6. It has better adaptability and fault tolerance to the deformation of the floor of the drying vehicle, and extends the service life of the floor of the drying vehicle.

[0036] It is understandable that both the fixture and the robotic arm can be connected to the remote control system of the production line. The remote control system can realize the coordinated movement control of the robotic arm and the fixture to ensure the orderly execution of operations such as positioning, gripping, lifting, tearing, peeling, moving and releasing of the rubber block 6. This allows the rubber block 6 to be completely peeled off from the drying car floor plate quickly and stably, so that the unloaded rubber block 6 can be transferred, weighed and packaged for subsequent processes. It also eliminates the need for workers to stay in the high-temperature and harsh working environment for a long time, greatly reducing the labor intensity of workers and reducing labor costs.

[0037] The frame unit 1 includes a main frame 1a and multiple sub-supports 1b. The multiple sub-supports 1b are symmetrically arranged on both sides of the main frame 1a with the main frame 1a as the center. There is a spacing 1d between adjacent main frames 1a and sub-supports 1b, and between every two adjacent sub-supports 1b, and they are connected to each other through a first hinge 1c.

[0038] The first drive unit 2 is provided with two components, each including a first hydraulic cylinder 2a, a second hinge 2b, and a first sleeve 2c. The two first hydraulic cylinders 2a are respectively arranged on both sides of the main frame 1a through the second hinge 2b. The output ends of the two first hydraulic cylinders 2a are respectively hinged to the two outermost sub-supports 1b through the first sleeve 2c.

[0039] It should be noted that the output ends of the two first hydraulic cylinders 2a push and pull the outermost sub-supports 1b at both ends of the frame unit 1, thereby realizing the state change of the frame unit 1. When the frame unit 1 is in the first state, the output ends of the two first hydraulic cylinders 2a extend and push the two ends of the frame unit 1 through the first sleeve 2c. The outermost sub-supports 1b at both ends move away from the main frame 1a. The movement of the outermost sub-supports 1b at both ends is transmitted to the adjacent sub-supports 1b and the main frame 1a in sequence through the first hinge 1c, so that there is a distance between each two adjacent sub-supports 1b and the adjacent main frame 1a. Both the support a and the sub-support 1b are separated from each other and form a gap 1d so that the bottom surface of the frame unit 1 forms a horizontal plane. When the frame unit 1 needs to be in the second state, the output ends of the two first hydraulic cylinders 2a retract and pull the two ends of the frame unit 1 through the first sleeve 2c. The outermost sub-supports 1b at both ends move towards the main frame 1a. The configured gap 1d provides space for each adjacent two sub-supports 1b and adjacent main frames 1a and sub-supports 1b to approach each other, so that the two ends of the frame unit 1 bend upward and extend, and the bottom surface of the frame unit 1 forms a convex arc surface.

[0040] The two first drive units 2 are configured to be staggered in the lateral direction. The positional limitation of the two first drive units 2 enables the first drive units 2 to achieve a stable push-pull effect on the end of the frame unit 1, and the frame unit 1 is less likely to experience serious displacement or excessive shaking during the change of state, so as to make the glue removal operation of this fixture more stable and efficient.

[0041] The gripper assembly 4 includes a hinge rod 4a, a fixed rod 4b, and multiple hooks 4c. One end of each hook 4c is hinged to the end of the frame unit 1 via the hinge rod 4a. The other end of each hook 4c has a sharp structure. The hooks 4c are arranged parallel to each other and spaced apart along the axis of the hinge rod 4a. The fixed rod 4b is disposed on the hook 4c and is parallel to the hinge rod 4a. The second drive unit 3 has two components, each including a second hydraulic cylinder 3a and a second sleeve 3b. The two second hydraulic cylinders 3a are located at both ends of the frame unit 1. The output ends of the two second hydraulic cylinders 3a are hinged to the two fixed rods 4b via the second sleeves 3b.

[0042] It should be noted that the output end of the second hydraulic cylinder 3a pushes and pulls the fixing rod 4b through the second sleeve 3b, driving the hook body 4c to perform a clamping or opening action. At the same time, the end of the hook body 4c has a sharp structure. Based on the above operation control, on the one hand, the hook body 4c in the two gripper assemblies 4 can be inserted to the bottom positions on both sides of the rubber block 6, stably hooking and clamping the rubber block 6, so as to stably perform the subsequent tearing action of the rubber block 6. On the other hand, the hook body 4c in the two gripper assemblies 4 can perform an opening action to release the rubber block 6.

[0043] The two second drive units 3 are configured to be staggered in the lateral direction. The position of the two second drive units 3 is limited by the weight of the two second drive units 3 as the left and right balance, so that the frame unit 1 is not prone to serious displacement or excessive shaking during the change of state, so as to make the glue removal operation of this fixture more stable and efficient.

[0044] It also includes a connection structure 5 for interconnecting with the robotic arm, the connection structure 5 being located at the top center of the frame unit 1. The connection structure 5 is a flange.

[0045] Understandably, the connecting structure 5 is used to allow the robotic arm and this fixture to be separated or integrated. When the robotic arm malfunctions, it can be quickly replaced on-site, avoiding production interruptions in the natural rubber processing production line.

[0046] Example 2 like Figure 4 , Figure 5 and Figure 6As shown, the natural rubber block peeling fixture also includes a connecting structure 5 for interconnection with the robotic arm. Two natural rubber block peeling fixtures are provided and arranged side-by-side in the front-rear direction. The connecting structure 5 is located at the top center between the two frame units 1, fixing the two natural rubber block peeling fixtures together. The connecting structure 5 is a flange.

[0047] It is understood that this embodiment is a further limitation and adjustment based on embodiment 1. The robotic arm is assembled with two natural rubber block peeling jigs at the same time through the connecting structure 5. After one positioning and alignment, it can peel off two rubber blocks 6 side by side at the same time, and then transport the two rubber blocks 6 at the same time, which greatly improves the rubber unloading efficiency.

[0048] Example 3 Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The present invention also provides a method for removing rubber, which is implemented using the aforementioned natural rubber block peeling clamp, and includes the following steps: Step 1: Install the natural rubber block peeling clamp at the end of the robotic arm; Step 2: For the rubber block 6 adhering to the drying cart, the robotic arm is used to move the natural rubber block peeling clamp, while the first drive unit 2 drives the frame unit 1 to change to the first state, so that the bottom surface of the frame unit 1 abuts against the upper surface of the rubber block 6. Step 3: The second drive unit 3 drives the two gripper assemblies 4 to perform a gripping action and inserts them into the bottom positions on both sides of the rubber block 6; Step 4: The first drive unit 2 drives the frame unit 1 to change to the second state. The two ends of the frame unit 1 are driven by two gripper assemblies 4 to gradually lift the two sides of the rubber block 6. At the same time, the rubber block 6 is gradually separated from the drying cart along the opposing path from the bottom edge position to the bottom center position on both sides until the two ends of the frame unit 1 bend upward and extend to the limit position. Step 5: Use the robotic arm to lift the natural rubber block peeling clamp so that the rubber block 6 is completely removed from the drying cart. Then move the rubber block 6 to the waiting station. The second drive unit 3 drives the two gripper assemblies 4 to perform an opening action and place the rubber block 6 in the waiting station. Step 6: Complete one peeling operation of rubber block 6, return to step 2, until all rubber blocks 6 are transferred from the drying cart to the waiting station.

[0049] It is understood that the natural rubber block peeling clamps described in Examples 1 and 2 can both achieve the simulation of manual tearing action through this rubber removal method, and quickly, effectively and stably peel the rubber block 6 completely from the dry vehicle floor.

A method for obtaining adhesive, characterized in that, The method is implemented using the natural rubber block peeling clamp as described in any one of claims 1 to 9, and includes the following steps: Step 1: Install the natural rubber block peeling clamp at the end of the robotic arm; Step 2: For the rubber block adhering to the drying cart, the robotic arm is used to move the natural rubber block peeling clamp, while the first drive unit drives the frame unit to change to the first state, so that the bottom surface of the frame unit abuts against the upper surface of the rubber block. Step 3: The second drive unit drives the two gripper assemblies to perform a gripping action and inserts them into the bottom positions on both sides of the rubber block; Step 4: The first drive unit drives the frame unit to change to the second state. The two ends of the frame unit drive the two sides of the rubber block to be gradually lifted through two gripper assemblies. At the same time, the rubber block is gradually separated from the drying cart along the opposing path from the bottom edge of its two sides to the bottom center, until the two ends of the frame unit bend upward and extend to the limit position. Step 5: Use the robotic arm to lift the natural rubber block peeling fixture so that the rubber block is completely removed from the drying cart. Then move the rubber block to the waiting station. The second drive unit drives the two gripper assemblies to perform an opening action and place the rubber block in the waiting station. Step Six: After completing one rubber block peeling operation, return to Step Two until all rubber blocks are transferred from the drying cart to the waiting station.
