Description

Technical Field

[0001] The utility model relates to the technical field of back plate automatic part taking and cloth hanging tooling, in particular to a back plate automatic part taking and cloth hanging tooling. Background Art

[0002] Low-pressure molding is a process method that uses very low injection pressure to inject packaging materials into the mold and quickly solidify them. Before low-pressure injection molding of the front guard plate, the leather needs to be pre-hung on the four leather positioning pins of the mold movable mold. After the leather is hung, the mold closing, injection molding, pressure holding, cooling, and part removal injection molding cycle operations are completed.

[0003] When using the existing back panel automatic picking and cloth hanging tooling, staff often find that most of the leather is automatically grabbed, hung and picked up using suction cups. When the suction cup grabs the leather, due to its soft texture, if it is not flattened before grabbing, the leather will become wrinkled and not smooth, which will reduce the product quality. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a back plate automatic taking and cloth hanging tool.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a back plate automatic picking and cloth hanging tooling, including a base plate and a hanging rail, a fixed mold is fixedly connected to the base plate, a movable mold is slidably connected to the base plate, a leather frame is fixedly connected to the base plate, a slider is slidably connected to the hanging rail, a first cylinder is fixedly connected to the slider, a rectangular block is fixedly connected to the piston rod of the first cylinder, a motor is fixedly connected to the rectangular block, a rotating plate is fixedly connected to the output shaft of the motor, a rectangular plate is fixedly connected to the rotating plate, and a sliding plate is slidably connected to the rotating plate. A sliding plate is connected, a first mounting frame is fixedly connected to the sliding plate, a second cylinder is fixedly connected to the rectangular plate, a second mounting frame is fixedly connected to the piston rod of the second cylinder, a plurality of suction cups are provided on the first mounting frame and the second mounting frame, a flattening structure is provided on the second mounting frame, the flattening structure is mainly composed of a rectangular groove, the rectangular groove is opened on the second mounting frame, two rotating shafts are rotatably connected in the rectangular groove, a rotating block is fixedly connected to the rotating shaft, a connecting rod is provided on the rotating block, and a pressure roller is rotatably connected to the connecting rod.

[0006] The effects achieved by the above components are as follows: the leather is stacked on the leather rack, and the control device is started through the operation panel to make the slider slide on the hanging rail and slide to the top of the leather rack, and the second cylinder is started, and the second cylinder drives the second mounting frame to descend, so that the four suction cups on the second mounting frame absorb and grab the leather, and the slider continues to slide. When the slider is above the fixed mold, the movable mold is slid to separate the movable mold from the fixed mold, and the motor is started. The output shaft of the motor drives the rotating plate to rotate, and the rotating plate rotates ninety degrees. The second cylinder is started, and the second cylinder drives the second mounting frame to approach the movable mold until the leather is hung on the positioning pin of the movable mold. At this time, the suction cup releases the limit of the leather, and the slider slides. The movable plate makes the first mounting frame approach the fixed mold, so that the four suction cups on the first mounting frame can pick up the product formed in the fixed mold. When picking up the leather, when the second mounting frame descends, it will drive the two rotating blocks to descend. Since the position of the pressure roller is lower than the suction cup, the two pressure rollers will preferentially contact the leather surface to flatten the leather, and in the process of the second mounting frame continuing to move downward, the two pressure rollers will automatically roll to both sides of the leather to make its surface flat before picking it up, thereby avoiding the situation where the leather is grabbed by the suction cup, due to its soft texture. If it is not flattened before grabbing, the leather will be wrinkled and not flat, thereby reducing the product quality.

[0007] Preferably, two first springs are sleeved on the rotating shaft, one end of the first spring is fixedly connected to the rotating block, and the other end of the first spring is fixedly connected to the inner wall of the rectangular groove.

[0008] The effect achieved by the above components is: when the pressure roller rolls on the leather surface, the first spring is in a twisted state, so when the leather is taken, the two rotating blocks will be reset under the rebound force of the first spring, and the elastic force of the first spring is much smaller than the suction force of the suction cup.

[0009] Preferably, two limit blocks are fixedly connected in the rectangular groove.

[0010] The effect achieved by the above components is that the two limit blocks can limit the rotating block, preventing the rotating block from rotating inwards under the action of the first spring and making it difficult to push outwards.

[0011] Preferably, a sliding groove is provided in the rotating block, a sliding rod is slidably connected in the sliding groove, and the sliding rod is fixedly connected to the connecting rod.

[0012] The effect achieved by the above components is that the slide bar slides down under the action of gravity, which can lengthen the length of the rotating block, thereby increasing the rolling range of the pressure roller.

[0013] Preferably, a second spring is fixedly connected to the slide rod, and one end of the second spring is fixedly connected to the inner wall of the slide groove.

[0014] The effect achieved by the above components is: when the pressure roller rolls on the leather, it pushes the slide bar to shrink into the slide groove, squeezing the second spring at this time, and the rebound force of the second spring acts on the slide bar, thereby increasing the pressure applied by the pressure roller on the leather and improving the flattening effect.

[0015] Preferably, a mounting structure is provided on both the first mounting frame and the second mounting frame, and the mounting structure is mainly composed of four fixing blocks, and the fixing blocks are fixedly connected to the first mounting frame and the second mounting frame, and circular holes are opened on the fixing blocks, and a round rod is fixedly connected to the suction cup, and the circular hole is adapted to the size of the round rod.

[0016] The effect achieved by the above components is that the round rod can be inserted into the round hole to install the suction cup, and a damaged suction cup can be easily replaced.

[0017] Preferably, four fixing plates are fixedly connected to the first mounting frame and the second mounting frame, limiting rods are slidably inserted on the fixing plates, and limiting grooves are provided on the round rods.

[0018] The effect achieved by the above components is that the limiting rod is inserted into the limiting groove to enhance the limiting effect on the suction cup.

[0019] Preferably, a third spring is sleeved on the limiting rod, one end of the third spring is fixedly connected to the limiting rod, and the other end of the third spring is fixedly connected to the fixing plate.

[0020] The effect achieved by the above components is: when the limit rod is stuck in the limit slot, the third spring is in a stretched state, so the rebound elastic force of the third spring acts on the limit rod, which can strengthen the connection effect between the limit rod and the limit slot.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are that, in the utility model, by setting a flattening structure, when the leather is taken, when the second mounting frame descends, the two rotating blocks will be driven to descend, and since the position of the pressure roller is lower than the suction cup, the two pressure rollers will preferentially contact the leather surface to flatten the leather, and in the process of the second mounting frame continuing to move downward, the two pressure rollers will automatically roll to both sides of the leather to make its surface flat before taking it, and when the pressure rollers roll on the leather surface, the first spring is in a twisted state, so when the taking is completed, the two rotating blocks will be reset under the action of the rebound elastic force of the first spring, and the elastic force of the first spring is much smaller than The suction force of the suction cup and the two limit blocks can limit the rotating block to prevent the rotating block from rotating inward under the action of the first spring and being difficult to push outward. The slide bar slides down under the action of gravity, which can lengthen the length of the rotating block, thereby increasing the rolling range of the pressure roller. When the pressure roller rolls on the leather, it will push the slide bar to shrink into the slide groove, squeezing the second spring at this time. The rebound elastic force of the second spring will act on the slide bar, thereby increasing the pressure applied by the pressure roller to the leather and improving the flattening effect, thereby avoiding the situation where the leather is wrinkled and not smooth enough when the suction cup grabs the leather due to its soft texture, if it is not flattened before grabbing, thereby reducing the product quality.

[0028] Reference Figure 3The second mounting frame 16 is provided with a flattening structure 8, which is mainly composed of a rectangular groove 81. The rectangular groove 81 is opened on the second mounting frame 16. Two rotating shafts 82 are rotatably connected in the rectangular groove 81. A rotating block 83 is fixedly connected to the rotating shaft 82. A connecting rod 84 is provided on the rotating block 83. A pressing roller 85 is rotatably connected to the connecting rod 84. The leather is stacked on the leather frame 5 and started by the operation panel control device, so that the slider 6 slides on the hanging rail 2 and slides above the leather frame 5. The second cylinder 14 is started. The second cylinder 14 drives the second mounting frame 16 to descend, so that the four suction cups 17 on the second mounting frame 16 absorb and grab the leather. The slider 6 continues to slide. When the slider 6 is located above the fixed mold 3, the movable mold 4 is slid so that the movable mold 4 Separate from the fixed mold 3, start the motor 11, the output shaft of the motor 11 drives the rotating plate 18 to rotate, the rotating plate 18 rotates ninety degrees, and the second cylinder 14 is started. The second cylinder 14 drives the second mounting frame 16 to approach the movable mold 4 until the leather is hung on the positioning pin of the movable mold 4. At this time, the suction cup 17 limits the leather, and slides the sliding plate 13, so that the first mounting frame 15 approaches the fixed mold 3, so that the four suction cups 17 on the first mounting frame 15 take the product formed in the fixed mold 3. When taking the leather, when the second mounting frame 16 descends, it will drive the two rotating blocks 83 to descend. Since the position of the pressure roller 85 is lower than the suction cup 17, the two pressure rollers 85 will preferentially contact the leather surface to flatten the leather, and as the second mounting frame 16 continues to move downward During the process, the two pressing rollers 85 will automatically roll to the two sides of the leather to make its surface flat before picking it up, thereby avoiding the situation that when the suction cup 17 grabs the leather, due to its soft texture, if it is not pressed flat before grabbing, the leather will be wrinkled and not flat, which will reduce the product quality. Two first springs 86 are sleeved on the rotating shaft 82, one end of the first spring 86 is fixedly connected to the rotating block 83, and the other end of the first spring 86 is fixedly connected to the inner wall of the rectangular groove 81. When the pressing roller 85 rolls on the leather surface, the first spring 86 is in a twisted state. Therefore, when the picking is completed, the two rotating blocks 83 will be reset under the action of the rebound elastic force of the first spring 86, and the elastic force of the first spring 86 is much smaller than the suction force of the suction cup 17. 1, there are two limit blocks 87 fixedly connected, the two limit blocks 87 can limit the rotating block 83, prevent the rotating block 83 from rotating inwardly under the action of the first spring 86, and make it difficult to push outward. A slide groove 88 is provided in the rotating block 83, and a slide rod 89 is slidably connected in the slide groove 88. The slide rod 89 is fixedly connected to the connecting rod 84. The slide rod 89 slides down under the action of gravity, which can lengthen the length of the rotating block 83, thereby increasing the rolling range of the pressure roller 85. A second spring 810 is fixedly connected to the slide rod 89, and one end of the second spring 810 is fixedly connected to the inner wall of the slide groove 88. When the pressure roller 85 rolls on the leather, the slide rod 89 will be pushed to shrink into the slide groove 88, at this time, the second spring 810 will be squeezed, and the rebound elastic force of the second spring 810 will act on the slide rod 89.This increases the pressure applied by the pressing roller 85 to the leather and improves the flattening effect.

[0029] Reference Figure 2 and Figure 4 The first mounting frame 15 and the second mounting frame 16 are both provided with a mounting structure 9, and the mounting structure 9 is mainly composed of four fixing blocks 91, and the fixing blocks 91 are fixedly connected to the first mounting frame 15 and the second mounting frame 16. A round hole 92 is opened on the fixing block 91, and a round rod 93 is fixedly connected to the suction cup 17. The round hole 92 is adapted to the round rod 93 in size, and the round rod 93 can be inserted into the round hole 92 to install the suction cup 17, which can facilitate the replacement of the damaged suction cup 17. The first mounting frame 15 and the second mounting frame 16 are both fixedly connected with four fixing plates 94, which are fixed A limit rod 95 is slidably inserted on the plate 94, and a limit groove 96 is provided on the round rod 93. The limit rod 95 is inserted into the limit groove 96 to enhance the limiting effect on the suction cup 17. A third spring 97 is sleeved on the limit rod 95, and one end of the third spring 97 is fixedly connected to the limit rod 95, and the other end of the third spring 97 is fixedly connected to the fixed plate 94. When the limit rod 95 is stuck in the limit groove 96, the third spring 97 is in a stretched state, so the rebound elastic force of the third spring 97 acts on the limit rod 95, which can enhance the connection effect between the limit rod 95 and the limit groove 96.

[0030] Working principle: stack the leather on the leather rack 5, start the control device on the operation panel, so that the slider 6 slides on the hanging rail 2 and slides to the top of the leather rack 5, start the second cylinder 14, the second cylinder 14 drives the second mounting frame 16 to descend, so that the four suction cups 17 on the second mounting frame 16 absorb and grab the leather, continue to slide the slider 6, when the slider 6 is above the fixed mold 3, slide the movable mold 4, so that the movable mold 4 is separated from the fixed mold 3, start the motor 11, the output shaft of the motor 11 drives the rotating plate 18 to rotate, the rotating plate 18 rotates ninety degrees, start the second cylinder 14, the second cylinder 14 drives the second mounting frame 16 to move closer to the movable mold 4 until the leather is hung on the movable mold 4, at this time, the limit of the leather on the suction cup 17 is released, and the sliding plate 13 is slid to make the first mounting frame 15 close to the fixed mold 3, so that the four suction cups 17 on the first mounting frame 15 can pick up the product formed in the fixed mold 3. When picking up the leather, when the second mounting frame 16 descends, it will drive the two rotating blocks 83 to descend. Since the position of the pressure roller 85 is lower than the suction cup 17, the two pressure rollers 85 will first contact the leather surface to flatten the leather, and when the second mounting frame 16 continues to move downward, the two pressure rollers 85 will automatically roll to both sides of the leather to make its surface flat before picking it up, thereby avoiding the suction cup 17 grabbing the leather. Since the leather is soft in texture, if it is not flattened before being grabbed, the leather will be wrinkled and not smooth enough, which will reduce the product quality. When the pressure roller 85 rolls on the leather surface, the first spring 86 is in a twisted state. Therefore, when the leather is picked up, the two rotating blocks 83 will reset under the rebound force of the first spring 86, and the elastic force of the first spring 86 is much smaller than the suction force of the suction cup 17. The two limit blocks 87 can limit the rotating block 83 to prevent the rotating block 83 from rotating inwardly under the action of the first spring 86 and being difficult to push outward. The sliding rod 89 slides down under the action of gravity, which can lengthen the length of the rotating block 83, thereby increasing the rolling range of the pressure roller 85. When rolling on the leather, the slide bar 89 will be pushed to shrink into the slide groove 88, and the second spring 810 will be squeezed at this time. The rebound elastic force of the second spring 810 will act on the slide bar 89, thereby strengthening the pressure applied by the pressing roller 85 to the leather and improving the flattening effect. The round rod 93 can be inserted into the round hole 92 to install the suction cup 17, which can facilitate the replacement of the damaged suction cup 17. The limiting rod 95 is inserted into the limiting groove 96 to strengthen the limiting effect of the suction cup 17. When the limiting rod 95 is stuck in the limiting groove 96, the third spring 97 is in a stretched state, so the rebound elastic force of the third spring 97 acts on the limiting rod 95, which can strengthen the connection effect between the limiting rod 95 and the limiting groove 96.
