Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to an automatic shunt detection device for an injection molding machine. Background Art

[0002] After the injection molded parts are demolded from the injection molding machine, they generally need to be precisely measured before entering the next production link. For the detection of injection molded parts, it is generally about their dimensions and surface defects. At present, most detection devices on the market require manual operation. The workpiece is clamped on the detection device by a person and then removed after the detection is completed. In this way, the detection time for each workpiece is relatively long, and the temperature of the injection molded parts coming out of the injection molding machine is relatively high. These injection molded parts need to be cooled to room temperature before their correct dimensions can be detected, so the detection time is further lengthened, resulting in low production efficiency.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN213918158U, patent name: An injection molded part detection device) is as follows: a machine body, a detection device, a horizontal turning device, a clamping device, and a vertical turning device. A detection table is provided on the machine body. The detection device is fixedly connected to the machine body. The horizontal turning device facilitates the horizontal rotation detection of the injection molded parts. The clamping device facilitates clamping injection molded parts of any size and can adjust the height of the injection molded parts after clamping. The vertical turning device facilitates the vertical rotation detection of the injection molded parts and can adjust the force of the vertical rotation so that it can stop and rotate at any angle. This injection molded part detection device solves the problems that it is difficult to adjust the fixation and turning of the existing injection molded part detection device at multiple angles, and it is difficult to stop and rotate the injection molded part at any angle during turning. The device is simple and fast to operate, can adjust the height of the injection molded parts after clamping, is convenient for detecting the injection molded parts from multiple angles and in all directions, improves the detection accuracy, and is convenient for people to use.

[0004] From the above implementation scheme, it can be seen that the injection molded part detection device requires a person to clamp the injection molded part on the detection device and then detect the dimensions of the injection molded part. Such a detection method requires many operation steps and takes a long time, resulting in low production efficiency of the production line. Summary of the Invention

Detailed implementation manners

[0057] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0058] As Figures 1 to 15As shown in the figure, an automatic shunt detection device for an injection molding machine includes a correction and alignment frame 2, which is connected to the injection molding part outlet of the injection molding machine 1. The correction and alignment frame 2 arranges the chaotic injection molding parts just output from the injection molding machine. The correction and alignment frame 2 is connected to a cooling drive assembly 4. The cooling drive assembly 4 includes a cooling fan 405, which cools the injection molding parts when transporting them. Due to the principle of thermal expansion and contraction, the temperature of the injection molding parts is relatively high when they are just produced by the injection molding machine, and the size of the injection molding parts will be larger. After the injection molding parts are cooled, their sizes basically reach a stable state. At one end of the cooling drive assembly 4 far from the correction and alignment frame 2, there is a sorting assembly 6. Since the time taken for arranging and cooling the injection molding parts is short, while the time taken for detecting the injection molding parts is long, the sorting assembly 6 can sort the arranged injection molding parts, and multiple detection assemblies 7 are used to detect the injection molding parts simultaneously, greatly improving the detection efficiency.

[0059] The sorting assembly 6 is connected to the detection assembly 7. The detection assembly 7 includes a weight detection group 701 and a dimension detection group 702. The weight detection group 701 screens out the first batch of defective products by detecting whether the weight of the injection molding parts is within the qualified range. The dimension detection group 702 screens out the second batch of defective products by detecting the inner and outer dimensions of the injection molding parts. The other end of the dimension detection group 702 is connected to the manual detection assembly 10.

[0060] The opening on the side of the material receiving groove 201 close to the injection molding machine 1 is larger than the opening on the side of the material receiving groove 201 close to the alignment and conveying section 202. The side of the material receiving groove 201 close to the injection molding machine 1 is higher than the side of the material receiving groove 201 close to the alignment and conveying section 202. Therefore, when the lampshade falls out of the injection molding machine, it first falls into the material receiving groove 201. Since the material receiving groove 201 is inclined, the lampshade slides from the high end of the material receiving groove 201 to the low end of the material receiving groove 201. At this time, the lampshades in the material receiving groove 201 are placed in an irregular shape.

[0061] The automatic shunt detection device of this embodiment mainly detects the injection-molded lampshade. The lampshade has a trumpet shape with one end small and the other end large. There is also an annular ring at the large end of the lampshade, which is the part with the largest cross-sectional area of the lampshade.

[0062] The temperature reduction driving component 4 includes a correction component 401 and a correction conveying component 402. The correction conveying component 402 is located inside the alignment conveying section 202, and the correction component 401 is located above the correction conveying component 402. The correction conveying component 402 includes a correction conveying motor 4021. The correction conveying motor 4021 is connected to a driving component 4022. The driving component 4022 is connected to a conveying circular belt 4024. The conveying circular belt 4024 is connected to a driven component 4023. The driving component 4022 includes a driving shaft 402A. Both ends of the driving shaft 402A are connected to driving wheels 402B. The conveying circular belt 4024 includes a first circular belt and a second circular belt. The first circular belt and the second circular belt are respectively connected to the two driving wheels 402B. The distance between the two driving wheels 402B is less than the maximum diameter of the injection molded part in the vertical direction, and the distance between the two driving wheels 402B is greater than the lateral dimension of the injection molded part. The driven component 4023 includes a driven shaft 402C. Both ends of the driven shaft 402C are connected to driven wheels 402D. The correction component 401 has the same structure as the storage pushing component 403. The correction component 401 includes a correction motor 4011. The correction motor 4011 is connected to a correction impeller 4012. The correction impeller 4012 includes a plurality of arc-shaped blades 401A distributed in a ring shape. The correction component 401 is used to push the injection molded part with its bottom or side facing above the conveying circular belt 4024, so that its direction rotates.

[0063] Therefore, when the lampshade is conveyed from the receiving chute 201 to the correction conveying component 402, if the small end of the lampshade faces downwards, the annular ring of the lampshade is placed on the two conveying circular belts 4024, and the other parts of the lampshade fall between the two conveying circular belts 4024. At this time, the rotation of the conveying circular belt 4024 drives the lampshade to move. When the bottom of the lampshade faces upwards, the entire lampshade is placed on the conveying circular belt 4024. At this time, the lampshade is driven by the conveying circular belt 4024 to move, and it will hit the correction component 401 located above the conveying circular belt 4024. The correction impeller 4012 of the correction component 401 deflects the lampshade, causing it to rotate, so that the small end of the lampshade faces downwards and the large end faces upwards. When the side of the lampshade faces downwards and falls between the two conveying circular belts 4024, since the distance between the two driving wheels 402B is greater than the lateral dimension of the injection molded part, the lampshade will directly fall between the two conveying circular belts 4024, and the lampshade falls into the recycling box 302.

[0064] A recycling component 3 is arranged on the side of the alignment correction frame 2. The recycling component 3 includes a recycling bin 302 and a recycling power unit 301. The recycling power unit 301 is arranged at one end of the recycling bin 302. The bottom of the recycling bin 302 is connected by a first inclined plate 3021 and a second inclined plate 3022. One end of the first inclined plate 3021 and the second inclined plate 3022 close to the recycling component 3 is lower than the end far from the recycling component 3. One end of the first inclined plate 3021 far from the alignment correction frame 2 is lower than the end close to the alignment correction frame 2. Therefore, the lamp shades falling into the recycling bin 302 will eventually fall to the lower end of the recycling power unit 301 along the inclined first inclined plate 3021 and the second inclined plate 3022.

[0065] The recycling power unit 301 includes a recycling motor 3011. The recycling motor 3011 is connected to a recycling conveyor belt 3012. A number of object-carrying plates 301A are arranged on the recycling conveyor belt 3012. Side guard plates 301B are arranged on both sides of the recycling conveyor belt 3012. The side guard plates 301B prevent the injection molded parts from falling off from the side during transportation. The recycling motor 3011 drives the recycling conveyor belt 3012 to rotate. The lamp shades are carried to a higher place by the recycling conveyor belt 3012 as the object-carrying plates 301A move, and finally fall into the receiving chute 201 from the upper end of the recycling power unit 301, and are re-conveyed to the alignment correction frame 2 together with the injection molded parts taken out from the injection molding machine for alignment.

[0066] The alignment correction frame 2 includes a material receiving groove 201. The material receiving groove 201 is connected to an alignment conveying section 202, and the alignment conveying section 202 is connected to a storage conveying section 203. A sliding strip 2031 is arranged inside the storage conveying section 203. After the lamp cover is transported by the conveying circular belt 4024 to the end farthest from the material receiving groove 201, it will be pushed onto the sliding strip 2031. The annular ring of the lamp cover hangs above the sliding strip 2031, and the small end of the lamp cover falls between the two sliding strips 2031. A storage pushing component 403 is arranged below the sliding strip 2031. The storage pushing component 403 is used to toggle the bottom end of the injection molded part, so that the injection molded part moves along the sliding strip 2031. The transportation mode of the storage pushing component 403 is different from that of the conveying circular belt 4024. The lamp cover is placed on the conveying circular belt 4024. If there are too many lamp covers in the front or blocked, due to the large contact area between the lamp cover and the conveying circular belt 4024, the friction force is large during transportation, and the lamp covers will pile up at one end of the conveying circular belt 4024. The piled-up lamp covers may cause the equipment to be stuck and malfunction. However, the storage pushing component 403 only toggles the lamp cover at the bottom, with a small contact area. When there are many lamp covers and the front end of the sliding strip 2031 is already full, the lamp covers can be temporarily stored on the sliding strip 2031. At this time, the storage pushing component 403 only toggles the lower part of the lamp cover to make the lower end shake until the lamp covers at the front end of the sliding strip 2031 are conveyed away, and the lamp covers at the rear end will move only when toggled by the storage pushing component 403. Therefore, the storage pushing component 403 plays a role in conveying the lamp covers, but at the same time can prevent the lamp covers from piling up on the conveying line and causing the conveying line to get stuck.

[0067] A heat dissipation partition 404 is arranged above the sliding strip 2031, and a heat dissipation fan 405 is located above the heat dissipation partition 404. The annular ring of the lamp cover is located between the sliding strip 2031 and the heat dissipation partition 404. Even if the lower end of the lamp cover is toggled by the storage pushing component 403, since the gap between the sliding strip 2031 and the heat dissipation partition 404 only allows the thickness of one annular ring to pass through, it further ensures that the lamp covers will not stack up on the sliding strip 2031. The wind of the heat dissipation fan 405 blows away the heat of the lamp cover through the heat dissipation partition 404, so that the lamp cover can be quickly cooled down.

[0068] One end of the sorting component 6 close to the alignment correction frame 2 is higher than the end far from the alignment correction frame 2. Therefore, when the lamp cover slides out from the sliding strip 2031 and falls to the sorting component 6, it will fall from the high end to the low end.

[0069] The sorting component 6 includes a sorting material rail 601, and a guiding rail 602 is arranged inside the sorting material rail 601. When the lamp cover falls into the sorting component 6, the annular ring of the lamp cover will slide from the upper end of the sliding strip 2031 to the upper end of the guiding rail 602. The guiding rail 602 plays a role in sliding transition for the lamp cover, preventing the lamp cover from tipping over when sliding down and destroying the arrangement rule of the lamp covers, so that the lamp cover can remain stable during the movement process.

[0070] The sorting material rail 601 includes a pre-sorting storage section 6011. One end of the pre-sorting storage section 6011 is bifurcated and connected with a first blanking channel 6012 and at least one second blanking channel 6013; a sorting door 603 is arranged at the connection port of the second blanking channel 6013 and the pre-sorting storage section 6011. When the sorting door 603 toggles towards the first blanking channel 6012, the lamp cover will slide to the second blanking channel 6013. When the sorting door 603 toggles towards the second blanking channel 6013, the lamp cover will slide to the first blanking channel 6012. Therefore, the lamp covers are sorted and conveyed.

[0071] A single out-of-line component 5 is arranged above one end of the guiding rail close to and away from the rectifying and arranging frame 2. The single out-of-line component 5 includes a positioning component 501 and a blocking component 502; the positioning component 501 includes a positioning lifting power component 5011. In this embodiment, the positioning lifting power component 5011 is a cylinder, and the output end of the positioning lifting power component 5011 is connected to a positioning rod 5012; the blocking component 502 includes a blocking lifting power component 5021. In this embodiment, the blocking lifting power component 5021 is a cylinder, and the output end of the blocking lifting power component 5021 is connected to a blocking plate 5022. Before blanking, the first lamp cover is in the position closest to the blocking plate 5022, and the positioning rod 5012 is in the lowered position. The positioning rod 5012 is inserted between the second lamp cover. When blanking, the blocking plate 5022 rises, and the first lamp cover falls into the first blanking channel 6012 or the second blanking channel 6013. The second lamp cover will not slide down because it is fixed by the positioning rod 5012. Then the blocking plate 5022 descends, the positioning rod 5012 rises, and the second lamp cover slides down to the position close to the blocking plate 5022. The positioning rod 5012 descends and is inserted between the third lamp cover, and so on, ensuring that only one lamp cover is discharged each time.

[0072] Above the detection component 7, a positioning and moving component 8 is provided. The positioning and moving component 8 includes a moving motor 801. The moving motor 801 is connected to a moving module 802. The moving module 802 is connected to a positioning and lifting component 803. In this embodiment, the positioning and lifting component 803 is a cylinder. The positioning and lifting component 803 is connected to a positioning member 804. The positioning member 804 is provided with a number of limiting rods 8041. When the positioning and lifting component 803 descends, the limiting rods 8041 surround the periphery of the lampshade. At this time, the moving module 802 drives the positioning member 804 to move, and then the lampshade can be driven to move. The movement of the positioning member 804 can drive the lampshade, so that the lampshade is respectively moved to the weight detection group 701, the size detection group 702, and finally moved to the manual detection component 10.

[0073] The weight detection group 701 includes a weighing component 7011. The weighing component 7011 is a weighing mat scale. The weighing component 7011 measures the weight of the lampshade. The lampshade with a weight within a certain range is a qualified product. If the weight is too low or too high, it means that the lampshade has certain defects and is a defective product. On one side of the weighing component 7011, a first motor 7012 is provided. The first motor 7012 is connected to a first extension plate 7013. The first extension plate 7013 is rotatably connected to the end of the weighing component 7011 away from the sorting component 6. The lampshade after weighing is driven by the positioning member 804 to the first extension plate 7013. If the lampshade is a finished product, the first extension plate 7013 extends to the size detection group 702, so that the lampshade can be subjected to the next round of detection. If the lampshade is a defective product, the first extension plate 7013 rotates downward. When the lampshade moves above the first extension plate 7013, it falls due to no support below and drops into the waste recycling bin 9.

[0074] The size detection group 702 includes an outer dimension detection component 7021. On both inner sides of the outer dimension detection component 7021, laser detectors 702A are provided. In the middle of the outer dimension detection component 7021, a middle hole 702B is provided. The lampshade is sent directly above the middle hole 702B, and the laser detectors 702A measure the outer dimensions of the lampshade by the principle of laser reflection.

[0075] Below the size detection group 702, there is an internal size detection component 703. The internal size detection component 703 includes a lifting module 7031. The lifting module 7031 is connected to a rotary cylinder 7032, and the rotary cylinder 7032 is connected to a detector 7033. The detector 7033 includes a detection seat 703A. The detection seat 703A is connected to a laser emitter 703B. A reflector 703C is arranged directly above the laser emitter 703B. The reflector 703C is arranged at a 45-degree inclination. Driven by the lifting module 7031, the detector 7033 rises from the middle hole 702B to the inside of the lamp cover. The laser emitter 703B emits laser light, which reaches the inner wall of the lamp cover through the reflection of the reflector 703C. As the lifting module 7031 drives the detector 7033 to rise, the detector 7033 measures the sizes of different positions inside the lamp cover. By measuring the internal and external sizes of the lamp cover, it is determined whether the lamp cover is a qualified product.

[0076] A second motor 7022 is arranged on the side of the peripheral size detection component 7021. The second motor 7022 is connected to a second extension plate 7023. The second extension plate 7023 is rotatably connected to one end of the peripheral size detection component 7021 away from the weight detection group 701. The measured lamp cover comes above the second extension plate 7023 driven by the positioning member 804. If the lamp cover is a qualified product, the second extension plate 7023 extends to the manual detection component 10, enabling the lamp cover to enter the next detection link. If the lamp cover is a defective product, the second extension plate 7023 rotates downward, and when the lamp cover moves above the second extension plate 7023, it will fall into the waste recycling bin 9 because it is not supported.

[0077] A waste recycling bin 9 is arranged below the detection component 7. The waste recycling bin 9 includes a box body 901. A drawer 903 is slidably inserted into the lower part of the box body 901. When the operator processes the waste, just pull out the drawer 903 and the waste will be taken out. To prevent the waste from piling up too high and getting stuck when the drawer is pulled out, a upper rotating plate 902 is rotatably connected to one side of the box body 901. When the height of the piled-up waste is higher than the highest end face of the drawer, the upper rotating plate 902 can rotate outward, enabling the drawer to be pulled out smoothly.

[0078] The lamp covers screened twice are conveyed to the manual detection component 10. The table board of the manual detection component 10 is made of light-transmitting frosted glass or PVC material. A lamp is arranged below the table board. The lamp can illuminate the injection molded part from the bottom upwards through the table board, facilitating manual detection of defects such as spots on the injection molded part. Therefore, compared with the traditional method of clamping and detecting injection molded parts individually, this automatic shunt detection method makes the detection of injection molded parts more accurate and efficient. Moreover, the operator only needs to observe the surface of the injection molded part, greatly reducing the labor intensity of the operator and making the working process of the operator simpler.

[0079] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
