Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a finished product receiving and detecting device for an injection molding machine. Background Art

[0002] In injection molding production, after the injection molded parts are formed, the mold of the injection molded parts will push the injection molded parts out. Some injection molded parts can be directly pushed to the discharge trough when being pushed out by the mold, and are tilted and unloaded by the feed trough. Some injection molded parts are fragile and need to be taken out with the assistance of mechanical clamps and other structures. At present, there are many automatic material picking mechanisms for injection molded parts on the market, most of which use suction cups to suck out the injection molded parts, and there is instability in sucking out the injection molded parts with suction cups alone. When the air pressure of the compressed air connected to the suction cup changes, it is easy to cause the injection molded parts to fall and be damaged. Therefore, some automatic material picking mechanisms will use grippers to assist in picking up the injection molded parts. When most injection molding machines are demolding, the injection molded parts are required to be pulled out in a direction perpendicular to the mold in order to be demolded smoothly. When the combined force direction of the grip of the gripper on the injection molded part and the suction of the suction cup on the injection molded part is inconsistent with the demolding direction of the injection molded part, it will cause the injection molded part to be demolded unsmoothly, which may cause the injection molded part to deform and produce defective products.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN117087112A, patent name: a device for picking up injection molded parts) is: the device for picking up injection molded parts includes a frame, on which are provided a clamping member, an adsorbing member and a moving component, wherein the clamping member can specifically be an automatic gripper for clamping the injection molded parts, the adsorbing member can specifically include a suction cup and an exhaust member, one end of the suction cup is provided with an adsorption port, the end of the suction cup close to the adsorption port is used to adhere to the surface of the injection molded part, the exhaust member is used to extract the air at the adsorption port so that a negative pressure is formed at the adsorption port, thereby realizing a fixed connection between the injection molded part and the suction cup, and the exhaust member can specifically be an air pipe connected to the adsorption port of the suction cup, an exhaust pump connected to the air pipe, and a pressure relief valve arranged on the air pipe. The method of using the adsorbent to absorb and pick up materials can be applied to the picking up of injection molded parts of various shapes and structures, and it can cooperate with the clamping part to achieve stable fixation of the injection molded parts; and the moving component is used to drive the clamping part and the adsorbent to move toward or away from the injection molded parts, so as to drive the injection molded parts out of the mold after they are fixed by the clamping part and the adsorbent, thereby finally achieving the picking up of the injection molded parts.

[0004] It can be seen from the above implementation scheme that the injection molded parts picking device is provided with an automatic gripper and a suction cup to take out the injection molded parts. However, it can be seen from the schematic diagram that the clamping direction of the automatic gripper is downward, and the suction direction of the suction cup is adjustable. Therefore, when clamping the injection molded parts, it is necessary to adjust the direction of the forces of the two to achieve a resultant force that is parallel to the demolding direction of the injection molded parts. The adjustment process is relatively complicated, and once the adjustment is not done properly, it is easy to cause damage to the injection molded parts. Summary of the invention

DETAILED DESCRIPTION

[0020] The preferred embodiments of the invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the invention, and are not used to limit the invention.

[0021] like Figures 1 to 16As shown, a finished product receiving and detecting device for an injection molding machine comprises a truss manipulator 2, which is arranged at one side of an injection molding machine 1, and is provided with an X-axis component 201, a Y-axis component 202, and a Z-axis component 203 connected together, and a material taking component 204 is hinged at the lower end of the Z-axis component 203, and the material taking component 204 can move along the X-axis, Y-axis and Z-axis directions relative to the injection molding machine 1; a cooling component 3, a sorting component 4 and a visual detection component 5 connected in sequence are also arranged at one side of the injection molding machine 1; The material picking component 204 includes a rotating seat body 2041, on which a suction cup 2042 is arranged, and a clamp 20A is arranged directly in front of the suction cup 2042. The clamping center point of the clamp 20A is coaxial with the suction point of the suction cup 2042. Therefore, when the injection molded part is grasped, the combined force of the force applied by the suction cup 2042 to the injection molded part and the force applied by the clamp 20A to the injection molded part can be consistent with the demolding direction of the injection molded part, so that the injection molded part can be demolded smoothly. Compared with the traditional method of grasping the injection molded part with only the suction cup 2042, this can avoid the suction cup 2042 from failing to grasp due to unstable air pressure during the grasping process. Setting the grasping force of the two on the injection molded part on the same axis can also avoid the injection molded part from being damaged during the demolding process, thereby ensuring the quality of the injection molded part.

[0022] After the mold of the injection molding machine 1 is opened, the rotating seat body 2041 rotates to a direction parallel to the Z axis and the X axis and perpendicular to the Y axis, and the rotating seat body 2041 enters the gap opened by the mold. After the injection molding machine mold pushes out the injection molded part, the rotating seat body 2041 approaches the injection molded part, the suction cup 2042 sucks one end of the injection molded part, and the clamp 20A clamps the middle part of the injection molded part. Then the material taking component 204 pulls the injection molded part out of the mold along the Y axis direction, and then the material taking component 204 withdraws to the top of the injection molding machine 1 along the Z axis direction. After withdrawing, the rotating seat body 2041 rotates to a direction parallel to the X axis and the Y axis and perpendicular to the Z axis. The rotating seat body 20 41 moves to the top of the cooling component 3, the suction cup 2042 no longer sucks one end of the injection molded part, the clamp 20A is loosened and no longer clamps the injection molded part, and the injection molded part is placed on the cooling component 3 for cooling; the cooling component 3 can quickly cool the injection molded part just taken out of the injection molded part, so that the injection molded part can form the outer dimensions set by the product at room temperature, and the sorting component 4 makes the injection molded parts line up with the large end facing up and the small end facing down, so as to facilitate the injection molded parts to be input into the visual inspection component 5, and the visual inspection component 5 uses the camera 5061 to quickly take pictures and analyze the injection molded parts, judge defective products and finished products, and transport the defective products and finished products separately.

[0023] The rotating seat body 2041 is connected to the clamping base plate 2043, the clamping base plate 2043 is provided with a clamping base shaft 20431, and the clamp 20A is connected to the clamping base shaft 20431; The clip 20A includes a first clamp body 20A1 and a second clamp body 20A2 which are hinged together. The first clamp body 20A1 and the second clamp body 20A2 are both provided with a soft padding strip on one side facing the injection-molded part, so that when the clip 20A clamps the injection-molded part, the part in contact with the injection-molded part is the soft padding strip. In this embodiment, the soft padding strip is a high-temperature resistant silicone strip. The use of the soft padding strip ensures that when the inner side of the clip contacts the injection-molded part, the injection-molded part will not be scratched, and no clamping marks will be formed on the outer side of the injection-molded part.

[0024] The first clamp body 20A1 is provided with a first rotating shaft hole 20A11, and the second clamp body 20A2 is provided with a second rotating shaft hole 20A23. The first rotating shaft hole 20A11 and the second rotating shaft hole 20A23 are both rotatably connected to the clamping base shaft 20431; the second clamp body 20A2 is provided with an interlocking groove 20A21, and the first clamp body 20A1 is movably plugged into the interlocking groove 20A21; an upper pull rod 20A13 is provided at one end of the first clamp body 20A1, and the upper pull rod 20A13 is vertically connected to the first swing pull shaft 20A12; an upper stop block 20A22 and a second swing pull shaft 20A24 are provided at one end of the second clamp body 20A2; when the first clamp body 20A1 and the second clamp body 20A2 rotate, the upper stop block 20A22 serves to limit the upper pull rod 20A13. Therefore, when the first clamp 20A1 and the second clamp 20A2 are closed toward the middle, the middle of the two can only merge into a circle and cannot continue to move toward the middle. This limits the pressure on both sides of the injection-molded part when the first clamp 20A1 and the second clamp 20A2 clamp the injection-molded part, avoiding deformation of the injection-molded part due to excessive clamping of the injection-molded part by the first clamp 20A1 and the second clamp 20A2.

[0025] Two clamping power members 20B are respectively arranged on both sides of the clamping base plate 2043, and the clamping power member 20B includes a clamping cylinder 20B1, and the output end of the clamping cylinder 20B1 is connected to the clamping push block 20B2, and the clamping push block 20B2 is provided with an active track groove 20B21; the first swing pull shaft 20A12 and the second swing pull shaft 20A24 are respectively connected to the clamping linkage rod 20C, and one end of the clamping linkage rod 20C is provided with a connecting plug shaft 20C1, and the connecting plug shaft 20C1 is connected to the clamping power member 20B, and the connecting plug shaft 20C1 is inserted into the active track groove 20B21 When the two clamping cylinders 20B1 push the clamping push block 20B2 toward the two sides of the clamping substrate 2043, the two clamping linkage rods 20C are pulled to move toward the two sides of the clamping substrate 2043 respectively, so that the first clamp 20A1 and the second clamp 20A2 are separated and do not clamp the injection molded part; when the two clamping cylinders 20B1 push the clamping push block 20B2 toward the middle of the clamping substrate 2043, the two clamping linkage rods 20C are pushed to move toward the middle of the clamping substrate 2043 at the same time, so that the first clamp 20A1 and the second clamp 20A2 are moved closer to the middle and clamp the injection molded part.

[0026] The material picking component 204 is connected to the rotating driving part 205, and the rotating driving part 205 is connected to the lower end of the Z-axis component 203. The rotating driving part 205 includes a rotating connecting seat 2051, and the rotating connecting seat 2051 is connected to the rotating motor 2052. The rotating connecting seat 2051 is rotatably connected to the second gear 2054, and the rotating motor 2052 is connected to the first gear 2053. The first gear 2053 is meshed and connected with the second gear 2054; the rotating seat body 2041 is provided with a rotating shaft 20411, and the rotating shaft 20411 is connected to the second gear 2054. Therefore, the rotating motor 2052 drives the first gear 2053 to rotate, and can drive the second gear 2054 to rotate through the meshing between gears, thereby realizing the rotation of the material picking component 204, so that the material picking component 204 is perpendicular to the plane formed by the X-axis and the Y-axis when entering the injection molding machine to pick up materials, and after the injection molded parts are taken out, the material picking component 204 can be rotated to a state parallel to the plane formed by the X-axis and the Y-axis, so that the injection molding machine can be stably placed on the cooling component 3.

[0027] The X-axis component 201 includes an X-rod body 2011, on which a first slide rail 2012 and a first rack 2013 are disposed, the first slide rail 2012 is slidably connected to a first moving seat 2014, the first moving seat 2014 is connected to a first motor 2015, and a gear connected to the first motor 2015 is meshedly connected to the first rack 2013; The Y-axis component 202 is connected to the first movable seat 2014, and the Y-axis component 202 includes a Y-rod body 2021, on which a second slide rail 2024 and a second rack 2025 are arranged, the second slide rail 2024 is slidably connected to the second movable seat 2023, the second movable seat 2023 is connected to the second motor 2026, the gear connected to the second motor 2026 is meshedly connected to the second rack 2025, and a counterweight 2022 is arranged at one end of the Y-rod body 2021 away from the second movable seat 2023; the counterweight 2022 makes the weight at both ends of the Y-rod body 2021 close to balance, avoiding that one end of the Y-rod body is too heavy and increases the lateral pulling force of the first movable seat 2014 on the first slide rail 2012, so that the Y-rod body is more stable during the movement, thereby ensuring the stable operation of the equipment.

[0028] The Z-axis component 203 includes a Z-direction drive seat 2031, which is connected to the second moving seat 2023. A third motor 2033 is arranged on the Z-direction drive seat 2031. The Z-direction drive seat 2031 is slidably connected to the Z-rod assembly 2032. The Z-rod assembly 2032 includes a Z-rod body 20321, which is connected to the third rack 20322 and the third slide rail 20323. The upper and lower ends of the Z-rod body 20321 are rotatably connected to the lifting synchronous wheel 20325, and the lifting synchronous wheel 20325 is connected to the lifting synchronous belt 20324; the Z-direction drive seat 2031 is slidably connected to the third slide rail 20323, and the Z-direction drive seat 2031 is connected to the lifting synchronous belt 20324; the gear connected to the third motor 2033 is meshed and connected to the third rack 20322, and the third motor 2033 drives the third rack 20322 The Z-rod assembly 2032 is lifted and lowered, and during the lifting process, the Z-drive seat 2031 drives the lifting timing belt 20324 to rotate. If the third motor 2033 fails, the third rack 20322 will drop uncontrollably, and the lifting timing belt 20324 will be connected to the lifting timing belt 20324, and the Z-drive seat 2031 will be connected to the lifting timing belt 20324, so that the Z-rod assembly 2032 will not be completely separated from the Z-drive seat 2031, so that the Z-rod assembly 2032 will not fall completely and injure the person or object under the Z-rod assembly 2032, thereby ensuring the safety of the equipment.

[0029] The cooling component 3 includes a conveying belt 301, a cooling fan 302 is arranged above the conveying belt 301, and a single output groove 303 is arranged at one end of the conveying belt 301. The inner groove size of the single output groove 303 is larger than the cross-sectional size of one injection molded part but smaller than the cross-sectional size of two injection molded parts. Therefore, only one injection molded part can be output through the single output groove 303 at a time, and the end of the single output groove 303 close to the cooling component 3 is higher than the end close to the sorting component 4. Due to gravity, after the injection molded part is conveyed to the single output groove 303, it will slide from the cooling component 3 to the sorting component 4.

[0030] The sorting component 4 includes two parallel transmission limit rollers 401, and the distance between the two transmission limit rollers 401 is greater than the smaller end of the injection molded part but smaller than the larger end of the injection molded part; the first section of the two transmission limit rollers 401 close to the cooling component 3 is higher than the end thereof close to the visual detection component 5, and when the injection molded part falls from the cooling component 3 to between the two transmission limit rollers 401, the smaller end of the injection molded part will fall to the lower side of the two transmission limit rollers 401, while the larger end will be stuck to the upper end of the two transmission limit rollers 401, one end of the transmission limit roller 401 is connected to the passive synchronous wheel 401, and the passive synchronous wheel 4011 is connected to the active synchronous wheel 4021 through a synchronous belt, and the active synchronous wheel 4021 is connected to the fourth motor 402; the two transmission limit rollers 401 both rotate toward the middle, so that when the injection molded part falls, no matter where it falls on the two transmission limit rollers 401, it will eventually be moved to the gap between the two transmission limit rollers 401.

[0031] A transition cover 403 is provided at one end of the transmission limit roller 401 close to the visual inspection component 5. Both sides of one end of the transition cover 403 cover both sides of the entrance 5011 of the inspection frame 501, so that the injection molded part can slide into the entrance 5011 smoothly.

[0032] The visual inspection component 5 includes an inspection frame 501, the inspection frame 501 is rotatably connected to a turntable 505, the inspection frame 501 is connected to a fifth motor 502, an outer rotating circle 503 is arranged on the inspection frame 501, the outer rotating circle 503 is rotatably connected to an inner rotating circle 504, the turntable 505 is connected to the inner rotating circle 504, and the turntable 505 is connected to the fifth motor 502; a plurality of product card slots 5051 are arranged on the circumference of the turntable 505, and a plurality of product card slots 5051 are arranged on the circumference of the inspection frame 501. There are an entrance 5011, a defective product exit 5012 and a finished product exit 5013. When the turntable 505 stops, the three product slots 5051 correspond to the entrance 5011, the defective product exit 5012 and the finished product exit 5013 respectively. Two discharging cylinders 507 are also arranged on the detection frame 501, and the output end of one discharging cylinder 507 is directly opposite to the defective product exit 5012, and the output end of the other discharging cylinder 507 is directly opposite to the finished product exit 5013. A visual inspection component 506 is arranged on the detection frame 501; the visual inspection component 506 includes a camera 5061, and the camera 5061 is arranged in the light ring 5062; when the turntable 505 does not rotate, in addition to the entrance 5011, the defective product exit 5012 and the finished product exit 5013, the other product slots 5051 are provided with visual inspection components 506 on both sides. After the injection molded part slides into the visual inspection component 5 from the sorting component 4, it is first at the entrance 5011, and then the turntable 505 rotates to the position where the visual inspection component 506 is provided for inspection. If the inspection result is that the injection molded part is defective, then when the injection molded part is rotated by the turntable 505 to the defective product outlet 5012, the ejection rod of the discharge cylinder 507 there extends to push out the injection molded part. When it is detected that the injection molded part is genuine, when the injection molded part passes through the defective product outlet 5012, the discharge cylinder 507 there does not move, and when the injection molded part moves to the finished product outlet 5013, the ejection rod of the discharge cylinder 507 there extends to push out the injection molded part, thereby separating the injection molded parts into genuine and defective products. The defective product outlet 5012 and the finished product outlet 5013 are both connected to the output guide rail 5014. After the injection molded part is pushed out of the visual inspection component 5, it can slide along the output guide rail 5014 to the corresponding collection point.

[0033] The equipment is provided with a truss robot 2, which can take out the injection molded parts from the injection molding machine without manual operation, so as to prevent the workers from being harmed by the high temperature of the injection molded parts. A cooling component 3 is also provided to quickly cool the injection molded parts so that the outer dimensions of the injection molded parts quickly reach the dimensions at room temperature. The injection molded parts are then sorted by a sorting component 4, and then the outer dimensions and injection surface defects of the injection molded parts are identified by a visual inspection component 5 to distinguish defective products from finished products. The defective products and finished products are then transported separately. The whole process does not require human intervention and is highly efficient.
