Description

Technical Field

[0001] This application relates to the field of injection molding machine processing, and in particular to an automatic feeding device for a blower injection molding machine. Background Technology

[0002] Rotors and shafts are used as components in fans or other rotating machinery. A rotor is a collection of parts that can rotate about a certain axis, usually including blades, while a shaft is a key component that supports the rotor and transmits the mechanical energy it generates to other mechanical parts.

[0003] In related technologies, traditional rotor and shaft feeding processes mainly rely on manual labor and semi-automatic equipment. Typically, the rotor and shaft are manually placed in designated positions and then assembled using semi-automatic equipment.

[0004] However, this feeding process has the following drawbacks: the traditional rotor and shaft feeding process relies heavily on manual operation, which increases the time cost of manual intervention and leads to low efficiency. Summary of the Invention

[0005] In order to reduce the time cost of manual intervention and improve production efficiency, this application provides an automatic feeding device for a blower injection molding machine.

[0006] The automatic feeding device for a blower injection molding machine provided in this application adopts the following technical solution:

[0007] An automatic feeding device for a blower injection molding machine includes a conveying mechanism, a positioning mechanism, and a second gripper. The conveying mechanism and the positioning mechanism are both mounted on the machine body. The positioning mechanism is provided with a first gripper. The conveying mechanism, in cooperation with the first gripper, conveys the rotor and shaft to the positioning mechanism. The second gripper assembles the rotor and shaft and conveys them into the injection molding machine.

[0008] By adopting the above technical solution, the rotor and shaft can be quickly and accurately transported to the designated position, reducing the time cost of manual intervention, improving production efficiency, and also reducing errors caused by human fatigue or negligence, thus lowering production risks.

[0009] Preferably, the conveying mechanism includes a rotor conveying assembly, which includes a first linear vibrator and a first conveying track. The first linear vibrator is mounted on the machine body, and the first conveying track is mounted on the first linear vibrator. One end of the first conveying track is located on one side of the positioning mechanism.

[0010] By adopting the above technical solution, with the first linear vibrator providing power, the first conveying track can continuously transport the rotor to one side of the positioning mechanism, which speeds up the production process, improves overall work efficiency, and reduces the need for manual intervention.

[0011] Preferably, the rotor conveying assembly further includes a ramp guide rail, the lower end of which is fixedly connected to the side of the first conveying track away from the positioning mechanism to form an inclined sliding path for the rotor.

[0012] By adopting the above technical solution, the operator can place the workpiece on the top of the inclined guide rail, and the rotor can be made to slide naturally down the inclined guide rail by its own gravity, thus realizing the continuity of the production process and improving efficiency.

[0013] Preferably, the conveying mechanism further includes a shaft conveying assembly, which includes a vibratory plate, a second linear vibrator, and a second conveying track. The shaft is placed in the vibratory plate, the second conveying track is mounted on the second linear vibrator, the second conveying track is fixedly connected to the vibratory plate, and the second conveying track extends to one side of the rotor conveying assembly.

[0014] By adopting the above technical solution, the shaft is automatically arranged into an orderly single row in the vibratory feeder, and then conveyed by the second linear vibrator through the second conveying track connected to the vibratory feeder. The rotor can be conveyed from one end of the second conveying track to the other end, reducing labor costs and improving production efficiency.

[0015] Preferably, a sensor is provided at the starting position of the second conveying track. The sensor includes a sensor and a controller, and the sensor and the controller are electrically connected to the conveying mechanism and the positioning mechanism.

[0016] By adopting the above technical solution, the sensor can detect the arrival status of the shaft in real time and transmit the signal to the controller. The controller adjusts the operation and pause of the conveying mechanism according to the signal feedback, thereby ensuring the precise connection between the shaft and the positioning mechanism.

[0017] Preferably, the positioning mechanism includes a positioning fixture, which has a plurality of positioning bosses arranged at equal intervals. The positioning bosses are vertically fixed to the upper surface of the positioning fixture, and the external structure of the positioning bosses matches the internal structure of the rotor, so that the first gripper grips the rotor and fits the rotor onto the positioning bosses.

[0018] By adopting the above technical solution, the outer wall of the positioning boss contacts the inner wall of the rotor, reducing the probability of the rotor moving or shifting during further operations. The first gripper can quickly and accurately place the rotor onto the positioning boss, reducing the need for manual operation. Multiple positioning bosses arranged at equal intervals allow multiple rotors to be processed simultaneously, improving production efficiency.

[0019] Preferably, the positioning boss is provided with a positioning groove, which matches the lower structure of the shaft, so that the first gripper inserts the lower structure of the shaft into the positioning groove.

[0020] By adopting the above technical solution, the positioning groove matches the lower structure of the shaft, ensuring that the shaft can be accurately aligned when placed. The lower surface of the upper end of the shaft contacts the upper surface of the positioning boss, further limiting the shaft and reducing the probability of offset and tilt. The first gripper achieves automated operation, which can quickly and accurately place the shaft onto the positioning boss, reducing the need for manual operation.

[0021] Preferably, the positioning mechanism further includes a linear module, the positioning fixture is mounted on the linear module, the linear module is horizontally arranged, the linear module is used to realize the transfer of the positioning fixture between the first gripper and the second gripper, the second gripper grips the shaft located on the positioning boss and inserts it into the rotor located on the positioning boss, and sends the assembled component into the injection molding machine.

[0022] By adopting the above technical solution, the linear module transfers the positioning fixture between the first gripper and the second gripper, realizing a continuous production process and improving production efficiency. The second gripper reconfirms and adjusts the position of the shaft, ensuring that the shaft can be accurately installed inside the rotor, thereby improving the overall assembly accuracy.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the conveying and positioning mechanisms, the rotor and shaft are conveyed quickly and accurately, which greatly improves production efficiency and reduces errors and risks caused by manual intervention;

[0025] 2. The first linear vibrator drives the first conveying track to automatically and continuously transport the rotor to the positioning mechanism, thereby improving production efficiency and reducing manual intervention;

[0026] 3. The sensor monitors the arrival status of the shaft in real time and transmits signals. The controller adjusts the operation and pause of the conveying mechanism according to the signal feedback, thereby ensuring the precise connection between the shaft and the positioning mechanism.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses an automatic feeding device for a blower injection molding machine. (Refer to...) Figure 2 An automatic feeding device for a blower injection molding machine includes a machine body, a conveying mechanism, a positioning mechanism, and a second gripper 7. The conveying mechanism, the positioning mechanism, and the second gripper 7 are all installed on the machine body. The coordinated work of the conveying mechanism, the positioning mechanism, and the second gripper 7 assembles the rotor and the shaft, and feeds the assembled finished product into the injection molding machine. This reduces the time cost of manual intervention, improves production efficiency, and also reduces errors caused by human fatigue or negligence, thus lowering production risks.

[0035] Reference Figure 3 The conveying mechanism includes a rotor conveying assembly 1 and a shaft conveying assembly 2. The rotor conveying assembly 1 conveys the rotor to the positioning mechanism, and the shaft conveying assembly 2 conveys the shaft to the positioning mechanism.

[0036] Specifically, the rotor conveying assembly 1 includes a ramp guide rail 11, a first conveying track 12, and a first linear vibrator 13. The ramp guide rail 11, the first conveying track 12, and the first linear vibrator 13 are all mounted on the machine body. The first conveying track 12 is mounted on the first linear vibrator 13. One end of the first conveying track 12 is located on one side of the positioning mechanism. The operator feeds the rotor into the ramp guide rail 11 accordingly. The lower end of the ramp guide rail 11 is fixedly connected to the side of the first conveying track 12 away from the positioning mechanism to form an inclined sliding path for the rotor.

[0037] Specifically, a support rod 111 is provided at the bottom of the starting end of the ramp guide rail 11. The lower surface of the bottom of the starting end of the ramp guide rail 11 is connected to the upper surface of one end of the support rod 111. The other end of the support rod 111 is vertically fixed to the machine body. The height of the support rod 111 is higher than the conveying plane of the first conveying track 12, thereby forming an inclination angle between the ramp guide rail 11 and the working plane of the first conveying track 12.

[0038] Furthermore, the end of the ramp guide rail 11 is fixedly connected to one end of the first conveying track 12 and is in communication with it. The tilt angle allows the rotor to slide autonomously along the path of the ramp guide rail 11 under the action of gravity, ensuring that the rotor can successfully slide to the first conveying track 12.

[0039] In addition, both the ramp guide rail 11 and the first conveying track 12 are long strips. Baffles are provided on both sides of the ramp guide rail 11 and the first conveying track 12. The baffles are vertically fixed to the ramp guide rail 11 and the first conveying track 12, which restricts the rotor from slipping due to lateral displacement during the sliding and conveying process.

[0040] Meanwhile, two first linear vibrators 13 are provided, arranged side by side and in contact with the upper plane of the machine body. Fixing strips 131 are provided on both sides of the two first linear vibrators 13, which are vertically fixed to the machine body to fix the two first linear vibrators 13, reducing the probability of the two first linear vibrators 13 shifting to the sides. The bottom plane of the first conveying track 12 is in close contact with the driving end face of the first linear vibrator 13. The vibration direction of the first linear vibrator 13 is consistent with the rotor movement path, which can continuously convey the rotor to one side of the positioning mechanism, speeding up the production process, improving the overall work efficiency, and reducing the need for manual intervention.

[0041] On the other hand, the shaft conveying assembly 2 includes a vibratory plate 21, a second linear vibrator 22 and a second conveying track 23. The shaft is placed in the vibratory plate 21, the second conveying track 23 is installed on the second linear vibrator 22, the second conveying track 23 is fixedly connected to the vibratory plate 21, and the second conveying track 23 extends to one side of the rotor conveying assembly 1.

[0042] Specifically, the vibratory feeder 21 is fixedly connected to the machine body by a fastener 211. The vibratory feeder 21 has a spiral guide rail inside that is fixedly connected to the second conveying rail 23. After the shaft is automatically arranged into an orderly single row by vibration in the vibratory feeder 21, it spirals upward along the guide rail. The shaft cap is locked in the guide rail by the locking mechanism of the vibratory feeder 21. The vibration of the vibratory feeder 21 transfers the shaft to the second conveying rail 23.

[0043] Furthermore, a limiting baffle 231 extending laterally along the second conveying track 23 is provided above the second conveying track 23. There is a certain gap between the lower surface of the limiting baffle 231 and the top of the shaft, ensuring that the shaft maintains the correct posture during transmission and reducing the probability of tilting and overturning. A guide guard plate 232 is provided on the outside of the second conveying track 23. There is a certain gap between the inner wall of the guide guard plate 232 and the tail column of the shaft. The guide guard plate 232 provides support from the outside to allow the shaft to move along a predetermined path.

[0044] Meanwhile, the second linear vibrator 22 is located at the bottom of the second conveying track 23. A fixed base 221 is provided at the bottom of the second linear vibrator 22. The fixed base 221 is fixedly connected to the machine body. The upper surface of the fixed base 221 is in contact with and fixedly connected to the bottom of the second linear vibrator 22. The bottom plane of the second conveying track 23 is in close contact with the driving end face of the second linear vibrator 22. The vibration direction of the second linear vibrator 22 is consistent with the axis movement path, which can continuously convey the axis to one side of the rotor conveying assembly 1.

[0045] Reference Figure 4 Furthermore, the conveying mechanism also includes a sensing element 3, which includes a sensor and a controller. The sensor and controller are electrically connected to the conveying mechanism and the positioning mechanism. Both the sensor and the controller are installed inside the second conveying track 23. In this embodiment, the sensor is an infrared sensor, which is fixed on the limiting baffle 231. The sensing end of the sensor is vertically facing the bottom inner wall of the second conveying track 23 near the vibrating plate 21. The sensor is used to detect the straight-line distance between the sensing end and the bottom of the second conveying track 23. Under normal conditions, the straight-line distance between the sensing end and the bottom of the second conveying track 23 is D1, that is, the axis is in the normal position and blocks the rays of the sensing end. When the axis is not in position, the straight-line distance between the sensing end and the bottom of the second conveying track 23 is D2, which is greater than D1, that is, the axis does not block the rays of the sensing end. The sensor can detect the arrival status of the axis in real time and transmit the signal to the controller. The controller adjusts the operation and pause of the conveying mechanism according to the signal feedback.

[0046] Reference Figure 5On the other hand, the positioning mechanism includes a positioning fixture 4, a first gripper 5, and a linear module 6. The linear module 6 is mounted on the machine body, and the positioning fixture 4 is fixedly mounted on a sliding seat. The sliding seat slides back and forth on the linear module 6, causing the positioning fixture 4 to move between the first gripper 5 and the second gripper 7.

[0047] In this embodiment, the first gripper 5 is configured as a first industrial robot, and the second gripper 7 is configured as a second industrial robot. The end effectors of the first and second industrial robots are integrated with a CCD vision system. Under the drive of the linear drive module, the first and second industrial robots can move in the X / Y / Z directions on the machine body.

[0048] Specifically, the positioning fixture 4 is provided with four positioning bosses 41 arranged in parallel. The positioning bosses 41 are vertically fixed to the upper surface of the positioning fixture 4. The first industrial robot sequentially places the rotor and the shaft on the positioning bosses 41, with the shaft and rotor arranged side by side. The linear module 6 transfers the positioning fixture 4 between the first industrial robot and the second industrial robot.

[0049] In addition, each positioning boss 41 is provided with a positioning groove 411 that is adapted to the structure of the shaft tail column, so that the first industrial robot can insert the tail column of the shaft into the positioning groove 411 through the CCD vision system. At the same time, the outer contour of the positioning boss 41 is perfectly matched with the geometry of the rotor cavity. When the first industrial robot clamps the rotor through the CCD vision system and presses it down in the vertical direction, the inner wall of the rotor and the outer wall of the boss form a guiding constraint, which lays the foundation for the subsequent precise assembly of the rotor and shaft. At the same time, the positioning fixture 4 also reduces the probability of slippage when transferring between the first industrial robot and the second industrial robot.

[0050] Furthermore, when the positioning fixture 4 moves to the working range of the second industrial robot via the linear module 6, the second industrial robot first uses precision grippers to grasp the tail of the shaft and insert it into the rotor. The external clamping mechanism simultaneously clamps the outer wall of the rotor and sends them into the injection molding machine together.

[0051] The implementation principle of the automatic feeding device for a blower injection molding machine in this application embodiment is as follows:

[0052] An automatic feeding device for a blower injection molding machine, through the coordinated work of a conveying mechanism, a positioning mechanism and a second gripper, quickly and accurately transports the rotor and shaft to a designated position, realizing the automated assembly of the rotor and shaft and feeding to the injection molding machine, reducing the time cost of manual intervention, improving production efficiency, and also reducing errors caused by human fatigue or negligence, thus lowering production risks.

[0053] The conveying mechanism includes a rotor conveying assembly and a shaft conveying assembly. The rotor conveying assembly includes a ramp guide rail, a first conveying track, and a first linear vibrator. The shaft conveying assembly includes a vibrating plate, a second conveying track, and a second linear vibrator.

[0054] The rotor slides onto the first conveying track driven by the first linear vibrator via the inclined guide rail. Relying on the vibration of the first linear vibrator and the constraints of the inclined guide rail baffle and the first conveying track, it is conveyed along a fixed path to one side of the positioning mechanism. The shaft center is arranged into a single row by the vibratory plate and transmitted to the second conveying track by the vibration of the vibratory plate. It is then transmitted to one side of the rotor conveying assembly via the second conveying track driven by the second linear vibrator. During the process, the rotor is maintained by the limit baffle and the guide guard plate. The limit baffle reduces the probability of tilting and overturning, and the guide guard plate provides support from the outside to make the shaft center move along the predetermined path. The infrared sensor monitors the position of the shaft center in real time, and triggers the controller to stop the conveying when there is an abnormality.

[0055] The positioning mechanism includes a positioning fixture and a first gripper, which is a first industrial robot and a second gripper, which is a second industrial robot. The upper surface of the positioning mechanism is provided with four low positioning bosses, and the positioning bosses are provided with positioning grooves. The first industrial robot uses a CCD vision system to grip the rotor and the shaft, and places them in the corresponding positions of the positioning bosses. The inner wall of the rotor contacts the outer wall of the positioning boss, and the tail column of the shaft is inserted into the positioning groove.

[0056] Once the rotor and shaft are successfully placed on the positioning fixture, the positioning fixture is then moved to the working area of ​​the second robot via a linear module. The second industrial robot uses a CCD vision system and precision grippers to grasp the tail of the shaft, inserts it vertically into the rotor cavity, and simultaneously clamps and fixes the outer wall of the rotor to complete the assembly. The assembled components are then transferred to the injection molding machine by the second robot.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
