Description

Technical Field

[0001] The present invention relates to the field of material clamps, and in particular to a material deformation clamping mechanism. Background Art

[0002] With the continuous improvement of automation technology, facing the increasing labor costs, more and more manufacturing companies are developing automated equipment to assist production. On the one hand, it can effectively reduce labor costs, and on the other hand, it eliminates human subjective factors and can effectively improve product production quality and production efficiency.

[0003] In automated production, the most common step involves product transfer, or moving a product from one location to another. For example, in the injection molding process, plastic parts are transferred from the mold to a conveyor belt. Or, in an automated spray painting line, workpieces to be sprayed (including but not limited to various plastic parts and hardware) are transferred from a conveyor belt to the spray booth. Therefore, the core challenge in automated production lies in how to smoothly drive the clamping mechanism to grasp and transfer the product. There are many different types of drive sources, including but not limited to pneumatic cylinders, motors, and their combinations.

[0004] However, the above-mentioned clamping mechanism has the following defects: when the driving source drives the clamp to grab the product, there must be no obstacles between the clamp and the product, especially for regularly arranged products, such as Figure 1 In the example of products arranged in rows and columns, the front products block the back products. When grabbing, the drive source can only drive the clamp to grab the front products first, and then grab the back products. It is impossible to grab them simultaneously, resulting in low grabbing efficiency. Therefore, in order to solve the above technical problems, the material deformation clamping mechanism of the present application is proposed. Summary of the Invention

[0026] In order to facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown.

[0027] See also Figures 1 to 3A material deformation clamping mechanism 10 includes a base plate 100 and an extension component 200. The base plate 100 is provided with a fixed clamping head 300. The extension component 200 includes a driving member 210, a main slide 220, a secondary slide 230, an elastic member 241, a side slide 250 and a connecting rod 260. The driving member 210 is provided on the base plate 100, the main slide 220 is slidably provided on the base plate 100, and the secondary slide 230 is slidably provided on the main slide 220. The secondary slide 230 and the driving member 210 are connected. The output shaft is connected, and the side slide 250 is slidably set on the main slide 220, and the sliding direction of the side slide 250 is perpendicular to the sliding direction of the secondary slide 230. The two ends of the connecting rod 260 are rotatably connected to the side slide 250 and the secondary slide 230 respectively. The two ends of the elastic member 241 are respectively in contact with the secondary slide 230 and the main slide 220. A dynamic chuck is provided on the side slide 250, and the driving member 210 is used to drive the side slide 250 to move so that the dynamic chuck and the fixed chuck 300 are arranged longitudinally.

[0028] It should be noted that the fixed chuck 300 is fixedly mounted on the base plate 100. The driving member 210 is fixedly mounted on the base plate 100, and the main slide 220 is slidably mounted on the base plate 100. For example, a guide rail is mounted on the main slide 220, and a slider is mounted on the base plate 100. The slider and the slide rail cooperate to enable the main slide 220 to slide relative to the base plate 110. The secondary slide 230 is slidably mounted on the main slide 220. Similarly, slide rails are mounted on the top and bottom surfaces of the main slide 220, and sliders are mounted on the base plate 100 and the secondary slide 230. The two slide rails of the main slide 220 cooperate with the sliders on the base plate 100 and the secondary slide 230, respectively, allowing the main slide 220 to slide relative to the base plate 100 and the secondary slide 230 to slide relative to the main slide 220 simultaneously. It should be noted that the direction in which the main slide 220 slides relative to the base plate 100 is the same as the direction in which the secondary slide 230 slides relative to the main slide 220. The secondary slide 230 is connected to the output shaft of the driver 210, and is driven by the driver 210 to slide. The side slide 250 is slidably mounted on the main slide 220. For example, the side slide 250 and the main slide 220 also cooperate with each other via slide rails and sliders. It should be noted that the direction in which the side slide 250 slides relative to the main slide 220 is perpendicular to the direction in which the secondary slide 230 slides relative to the main slide 220. The connecting rod 260 is rotatably connected at both ends to the secondary slide 230 and the side slide 250, respectively, allowing the side slide 250 and the secondary slide 230 to slide synchronously. Because the sliding direction of the side slide 250 is perpendicular to the sliding direction of the secondary slide 230, the side slide 250 is in an outwardly extended position relative to the secondary slide 230. The elastic member 241 is abutted at both ends against the secondary slide 230 and the main slide 220. A dynamic chuck is mounted on the side slide 250.

[0029] The following describes the working principle of the material deformation clamping mechanism 10. In its natural state, the output shaft of the driver 210 is retracted, and the dynamic chuck and the fixed chuck 300 are on the same starting line. For ease of description, the positions of the dynamic chuck and the fixed chuck 300 at this time are defined as being arranged horizontally. When the output shaft of the driver 210 is actuated, the driver 210 pushes against the secondary slide 230. Since the secondary slide 230 can slide relative to the primary slide 220, and the primary slide 220 can slide relative to the base plate 100, the secondary slide 230 and the primary slide 220 are supported by the elastic member 241. The elastic force of the elastic member 241 reduces the sliding friction between the primary slide 220 and the base plate 100. The secondary slide 230 and the primary slide 220 are integrally formed, so the driver 210 drives the primary slide 220 to slide relative to the base plate 100. For ease of description, the sliding directions of the primary and secondary slides 220 and 230 are both defined as longitudinal sliding, while the sliding direction of the side slide 250 is defined as transverse sliding. Since there is no sliding between the secondary slide 230 and the primary slide 220, there is also no sliding between the side slide 250 and the primary slide 220. This allows the dynamic chuck mounted on the side slide 250 to be driven by the primary slide 220 to pass the fixed chuck 300. When the primary slide 220 slides a certain distance, it should be noted that the distance the primary slide 220 slides depends on the front-to-back distance between the two products in actual production. At this time, the main slide 220 is stuck by the bottom plate 100, making it impossible for the main slide 220 to continue sliding, which is equivalent to the main slide 220 and the bottom plate 100 being fixed as a whole. As the driving member 210 continues to move, the secondary slide 230 is pushed by the driving member 210, and then overcomes the elastic thrust of the elastic member 241, causing the secondary slide 230 to slide relative to the main slide 220. The secondary slide 230 drives the side slide 250 to slide horizontally relative to the main slide 220 through the connecting rod 260, thereby driving the dynamic clamp on the side slide 250 to slide horizontally to the rear of the fixed clamp 300. For the sake of convenience of description, the position between the dynamic clamp and the fixed clamp 300 at this time is defined as longitudinal arrangement, so that the dynamic clamp and the fixed clamp 300 can clamp the products in the front and rear positions at the same time, realizing synchronous grasping. After the product is grasped, as the output shaft of the driving member 210 contracts, the elastic member 241 will first extend to its initial position because it will respectively support the secondary slide 230 and the main slide 220. During this process, the side slide 250 will drive the movable chuck to slide in the opposite direction, and finally pull the movable chuck back so that the movable chuck and the fixed chuck 300 return to the horizontal position. In this way, the material deformation clamping mechanism 10 of the present application can make the movable chuck and the fixed chuck 300 switch between horizontal and vertical arrangements, and can achieve synchronous grasping of products arranged in rows and columns, effectively improving grasping efficiency.

[0030] See also Figures 1 to 3 In one embodiment, a limit block 500 is provided on the base plate 100, the main slide 220 is passed through the limit block 500, a clamping block 270 is provided on the end of the main slide 220, and the driving member 210 is used to drive the clamping block 270 to approach or move away from the limit block 500.

[0031] It should be noted that the limit block 500 is mounted on the base plate 100 so that the main slide 220 passes through the bottom of the limit block 500, and the driving member 210 is fixedly mounted on the limit block 500. In this way, when the driving member 210 pushes the secondary slide 230, the secondary slide 230 and the main slide 220 can maintain a force balance, thereby enabling smooth sliding. The clamping block 270 is fixedly mounted on the main slide 220 so that the limit block 500 clamps the clamping block 270, thereby fixing the position of the main slide 220 and the base plate 100.

[0032] See also Figure 1 and Figure 4 In one embodiment, a buffer rod 280 is provided on the clamping block 270, and the buffer rod 280 is aligned with the limit block 500. It should be noted that when the main slide 220 slides to drive the clamping block 270 to abut against the limit block 500, the buffer rod 280 abuts against the limit block 500, reducing the impact force on the main slide 220 and preventing damage.

[0033] See also Figures 1 to 3 In one embodiment, the fixed chuck 300 includes an air gripper 310 and two clamping blocks 320. The air gripper 310 is arranged on the base plate 100. The two clamping blocks 320 are both arranged on the output shaft of the air gripper 310. The air gripper 310 is used to drive the two clamping blocks 320 to close or open each other.

[0034] It should be noted that the air gripper 310 is fixedly mounted on the base plate 100 , and the two clamping blocks 320 are respectively mounted on the output shafts of the air gripper 310 , so that the air gripper 310 drives the two clamping blocks 320 to move closer to or away from each other to achieve an open or closed clamping function.

[0035] In one embodiment, the fixed chuck 300 is a vacuum suction cup, which can suck up smooth products.

[0036] Furthermore, in one embodiment, the structure of the dynamic chuck is identical to that of the fixed chuck 300. For example, the dynamic chuck may be a combination of an air gripper 310 and two clamping blocks 320, or a vacuum suction cup.

[0037] Furthermore, in one embodiment, the driving member 210 is a cylinder. Thus, the material deformation clamping mechanism 10 of the present application can transform the single stroke of the cylinder into a combined stroke capable of sliding in both the horizontal and vertical directions, thereby eliminating the need for a driving member and making the structure more compact and reducing the weight of the structure.

[0038] See also Figures 1 to 3 In one embodiment, a fisheye joint 290 is provided at both ends of the connecting rod 260, and the two fisheye joints 290 are rotatably connected to the secondary slide 230 and the side slide 250 in a one-to-one correspondence.

[0039] It should be noted that the fisheye joint 290 allows the connecting rod 260 to rotate smoothly with the secondary slide 230 and the side slide 250 , thereby enabling the side slide 250 to slide reliably and synchronously with the secondary slide 230 .

[0040] See also Figure 3 In one embodiment, the expansion component 200 further includes a guide rod 242 , one end of the guide rod 242 is disposed on the secondary slide 230 , the other end of the guide rod 242 is passed through the main slide 220 , and the elastic member 241 is sleeved inside the guide rod 242 .

[0041] It should be noted that, in one embodiment, the elastic member 241 is a spring. In order to prevent the spring from deforming when compressed, a guide rod 242 is installed on the secondary slide 230 so that the guide rod 242 passes through the spring. At the same time, the guide rod 242 also passes through the main slide 220, thereby achieving a guiding effect on the elastic member 241.

[0042] See also Figures 1 to 3 In one embodiment, two side slides 250 are provided, and two connecting rods 260 are provided. The two side slides 250 are both slidably provided on the main slide 220, and one end of the two connecting rods 260 is rotatably connected to the secondary slide 230, and the other ends of the two connecting rods 260 are rotatably connected to the two side slides 250 in a one-to-one correspondence.

[0043] It should be noted that, in one embodiment, two fixed chucks 300 are provided, and the two fixed chucks 300 are respectively located at the two ends of the bottom plate 100 in the horizontal direction. Furthermore, two dynamic chucks are also provided, and correspondingly, two side slides 250 are also provided. The two side slides 250 are both slidably mounted on the main slide 220, and the two side slides 250 are respectively connected and driven by two connecting rods 260. In this way, when arranged horizontally, the two dynamic chucks are both located between the two fixed chucks 300, so that the two dynamic chucks are both located in a straight line with the two fixed chucks 300. In the longitudinal arrangement state, after the two dynamic chucks slide out from the two fixed chucks 300, and then slide horizontally to the rear of the two fixed chucks 300, they can simultaneously grasp four products arranged in rows and columns, realize synchronous material picking, and improve grasping efficiency.

[0044] In one embodiment, the maximum travel of the driving member 210 is greater than the maximum distance between the locking block 270 and the limiting block 500 .

[0045] It should be noted that, in this way, when the driving member 210 drives the main slide 220 to slide, when the blocking block 270 abuts against the limiting block 500 , the output shaft of the driving member 210 can continue to drive the secondary slide 230 to continue sliding relative to the main slide 220 .

[0046] See also Figures 1 to 4 In one embodiment, the material deformation clamping mechanism 10 further includes a support base 600, on which the base plate 100 is slidably mounted. Thus, when a screw module driven by a cylinder or a motor is mounted on the support base 600, the fixed chuck 300 and the movable chuck can be driven to slide together toward or away from the product.

[0047] It should be noted that if Figure 1 The four vertical rods shown are product placement locations, but the products are not limited to a cylindrical structure. It only shows that the products are arranged in rows and columns, and the products at the back are blocked by the products at the front.

[0048] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
