Abstract
Description
Technical Field
[0001] This application relates to the field of production and processing technology, and in particular to a rapid in-mold transport mechanism and processing production line. Background Technology
[0002] In existing technology, after a punch press completes a mold opening and closing process, the product cannot be automatically unloaded and needs to be taken out from inside the mold. At the same time, the product is also prone to scratches, and manual handling is not possible, which can lead to personal safety risks. Using other material handling mechanisms (such as robotic arms, modules, etc.) results in a longer material handling time due to the limited speed and accuracy of material handling, which to some extent limits the improvement of production efficiency. Summary of the Invention
[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a rapid in-mold material handling mechanism and processing production line, which can simultaneously pick up materials during mold opening, thereby improving processing efficiency and the safety of material handling.

[0030] In existing technology, after a punch press completes a mold opening and closing process, the product cannot be automatically unloaded and needs to be taken out from inside the mold. At the same time, the product is also prone to scratches, and manual handling is not possible, which can lead to personal safety risks. Using other material handling mechanisms (such as robotic arms, modules, etc.) results in a longer material handling time due to the limited speed and accuracy of material handling, which to some extent limits the improvement of production efficiency.
[0031] Based on this, this application provides a rapid in-mold handling mechanism and processing production line to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.
[0032] Firstly, referring to Figure 1 This application provides a rapid in-mold transfer mechanism, including: a frame 100, a lower template 200, an upper template 300, and a linkage structure. The side wall of the frame 100 is provided with a guide structure and a gripping structure. The gripping structure is movably disposed on the guide structure and is used to guide the gripping structure to move horizontally. The lower template 200 is disposed on the frame 100. The upper template 300 is movably disposed above the lower template 200 and is used to cooperate with the lower template 200 to press the workpiece. One end of the linkage structure is connected to the upper template 300, and the other end is connected to the guide structure. The linkage structure is used to drive the gripping structure to move closer to the lower template 200 when the upper template 300 moves away from the lower template 200; or, when the upper template 300 moves closer to the lower template 200, it drives the gripping structure to move away from the lower template 200.
[0033] The side wall of the frame 100 is provided with a guide structure and a gripping structure. The gripping structure is movably mounted on the guide structure. Through the action of the guide structure, the gripping structure can only move horizontally when driven, that is, it can move towards or away from the lower template 200 horizontally. When the gripping structure approaches and is above the lower template 200, the gripping structure removes the stamped workpiece located on the lower template 200. In addition, one end of the linkage structure is connected to the upper template 300, and the other end is connected to the guide structure, as shown in the figure. Figure 4 When the upper mold plate 300 moves away from the lower mold plate 200 (i.e., when the mold opens), the upper mold plate 300, through the action of the linkage structure, drives the material gripping structure to approach the lower mold plate 200 and remove the workpiece from the lower mold plate 200. (Refer to...) Figure 3When the upper template 300 approaches the lower template 200 (i.e. when the mold is closed), the upper template 300, through the action of the linkage structure, drives the material gripping structure to leave from above the lower template 200, thus entering the next punching process. At the same time, it can also simultaneously bring out the processed part. This application converts the vertical power of the upper template 300 into the horizontal power of the material gripping structure through the linkage structure, which can realize material picking simultaneously when the mold is opened, improving processing efficiency and material picking safety.
[0034] Reference Figure 1 and Figure 2 It is understood that the guiding structure includes a back plate 111, a fixing plate 112, and a guide shaft 113. The back plate 111 is disposed on the side wall of the frame 100, and the back plate 111 has a first guide hole 114 in the horizontal direction. There are two fixing plates 112, which are respectively located on both sides of the back plate 111. The two ends of the guide shaft 113 are respectively connected to the two fixing plates 112, and the guide shaft 113 is parallel to the first guide hole 114. The material gripping structure can be movably inserted through the guide shaft 113 and inserted into the first guide hole 114. By setting the first guide hole 114 and the guide shaft 113, the position of the material gripping structure is restricted. When the upper template 300 transmits power to the material gripping structure through the linkage structure, due to the action of the first guide hole 114 and the guide shaft 113, the power is converted into the power to drive the material gripping structure to move horizontally. Specifically, there can be two guide shafts 113 to provide stability for directional guidance.
[0035] Reference Figures 1 to 4 It is understood that the material-grabbing structure includes a movable block 121 and a material-grabbing component. The movable block 121 is movably mounted on the guide shaft 113, and the lower end of the material-grabbing component passes through the movable block 121 and is inserted into the first guide hole 114. The guide shaft 113 mainly guides the movement direction of the movable block 121, and the first guide hole 114 mainly guides the movement direction of the material-grabbing structure. At the same time, the material-grabbing component passes through the movable block 121, and the two provide a certain constraint. The other end of the linkage structure is specifically connected to the movable block 121. When the position of the upper template 300 changes, the linkage structure drives the movable block 121 to move along the length of the guide shaft 113, and at the same time drives the constrained material-grabbing component to move along the length of the first guide hole 114, thereby achieving simultaneous material grabbing during mold opening, improving processing efficiency and material grabbing safety.
[0036] Reference Figure 2It is understood that the material handling assembly includes a first vertical plate 123, a material handling component, a connecting shaft 122, a first bearing 124, and a second bearing 125. One end of the connecting shaft 122 is inserted into the lower part of the first vertical plate 123 through the first bearing 124, and passes through the movable block 121 and the second bearing 125 in sequence and is inserted into the first guide hole 114. The back plate 111 is provided with a sliding groove 115 matching the second bearing 125 at a position around the first guide hole 114. The second bearing 125 is disposed in the sliding groove 115. The back plate 111 is also provided with a first guide rail parallel to the first guide hole 114. The first vertical plate 123 is slidably disposed on the first guide rail through the first slider 118. The material handling component is disposed at the upper end of the first vertical plate 123. The back plate 111 is provided with a sliding groove 115 matching the second bearing 125 at the circumferential position of the first guide hole 114. When the material picking assembly moves, the second bearing 125 can drive the connecting shaft 122 to roll in the sliding groove 115. The other end of the connecting shaft 122 rolls in the first vertical plate 123 through the first bearing 124, so that the material picking assembly can slide more smoothly along the first guide hole 114. In addition, the first vertical plate 123 is slidably set on the first guide rail through the first slider 118, which further improves the smoothness of the movement of the material picking assembly and improves the stability of material picking.
[0037] Reference Figure 2 and Figure 4It is understood that the back plate 111 is provided with a second guide hole 116 in the vertical direction. The upper end of the second guide hole 116 is connected to the end of the first guide hole 114 away from the material picking component. The movable block 121 is provided with an oblique hole 129. The connecting shaft 122 passes through the oblique hole 129 on the movable block 121 and the first guide hole 114 or the second guide hole 116 on the back plate 111 in sequence. The material picking component also includes a second vertical plate 126. The second vertical plate 126 is disposed between the first vertical plate 123 and the first slider 118. The second vertical plate 126 is slidably disposed on the first guide rail through the first slider 118. The second vertical plate 126 is provided with a second guide rail 127 on the side of the second vertical plate 123 close to the first vertical plate 123. The second guide rail 127 is parallel to the second guide hole 116. The first vertical plate 123 is slidably disposed on the second guide rail 127 through the second slider 128. During the mold opening process, the upper mold plate 300 gradually moves away from the lower mold plate 200 until the connecting shaft 122 reaches the end of the first guide hole 114. At this time, the upper mold plate 300 continues to move upward a short distance. Due to the constraint between the inclined hole 129 on the movable block 121 and the connecting shaft 122, the connecting shaft 122 will move downward along the second guide hole 116. In addition, through the action of the second guide rail 127 and the second slider 128, the stability of the first vertical plate 123 relative to the second vertical plate 126 is improved. When the first vertical plate 123 moves downward, it will drive the material picking component to move downward, so that the material picking component contacts the workpiece on the lower mold plate 200 to pick up the workpiece. Similarly, during mold closing, the upper mold plate 300 gradually approaches the lower mold plate 200. Due to the constraint between the inclined hole 129 on the movable block 121 and the connecting shaft 122, the connecting shaft 122 moves upward along the second guide hole 116 until it reaches the end of the first guide hole 114. As the upper mold plate 300 continues to approach the lower mold plate 200, the connecting shaft 122 moves along the direction of the first guide hole 114, thus exiting between the lower mold plate 200 and the upper mold plate 300. Through the above steps, material removal is achieved simultaneously during mold opening, without the need for manual intervention, improving processing efficiency and the safety of material removal.
[0038] Reference Figure 1 , Figure 3 and Figure 4 It is understood that the material handling component includes a connecting frame 131, an extension plate 132, and several suction nozzles 133. The end of the connecting frame 131 is connected to the upper end of the first vertical plate 123. One side of the extension plate 132 is disposed on the connecting frame 131, and the other side of the extension plate 132 protrudes from the connecting frame 131 toward the lower template 200. The suction nozzles 133 are spaced apart on the extension plate 132. The other side of the extension plate 132 protrudes from the connecting frame 131 toward the lower template 200 to more easily reach the position of the workpiece. The workpiece is picked up by the spaced suction nozzles 133, thereby achieving the purpose of simultaneous material handling during mold opening.
[0039] Reference Figure 1 , Figure 3 and Figure 4 It is understood that there are two guiding structures. The material gripping structure includes two movable blocks 121, which are located on both sides of the frame 100 and can be movably inserted through the corresponding guide shafts 113. The material picking assembly includes two first vertical plates 123, which are located on both sides of the frame 100. The two ends of the connecting frame 131 are respectively connected to the upper ends of the two first vertical plates 123. That is, guiding structures are provided on both sides of the frame 100 to guide the material gripping structure, which improves the balance of force applied by the material gripping structure when it moves and prevents the material gripping structure from shaking and causing the positions of the two ends to shift, so as to ensure that the material gripping structure can complete the operation of picking up material from the lower template 200.
[0040] Continue to refer to Figure 1 , Figure 3 and Figure 4 It is understood that the linkage structure includes a first link 410, a second link 420, and a third link 430. A fixing block 440 is also provided on the side of the back plate 111. One end of the first link 410 is rotatably connected to the upper mold, one end of the second link 420 is rotatably connected to the movable block 121, one end of the third link 430 is rotatably connected to the fixing block 440, and the other ends of the first link 410, the second link 420, and the third link 430 are rotatably connected. The first link 410 and the second link 420 are connected to movable parts at one end, and the third link 430 is connected to a fixed part at one end. At the same time, the other ends of the first link 410, the second link 420 and the third link 430 are rotatably connected and mutually constrained. The lengths of the first link 410, the second link 420 and the third link 430 are fixed. When the angle of the first link 410 changes, the power will be transmitted to one end of the second link 420 through the constraint between the three, thereby pulling the movable block 121 to move. That is, through the linkage of the three, the vertical power of the upper template 300 can be converted into the horizontal power of the material grabbing structure, and the material can be picked up simultaneously when the mold is opened, improving processing efficiency and the safety of material picking.
[0041] Secondly, this application also provides a processing production line, including a rapid in-mold transfer mechanism according to any embodiment of the first aspect. The function and principle of the processing production line in this embodiment are based on the above-mentioned rapid in-mold transfer mechanism. Therefore, the processing production line in this embodiment has the same beneficial effects as the above-mentioned rapid in-mold transfer mechanism, and will not be repeated here for the sake of saving space.
[0042] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
