Description

Technical Field

[0001] The present invention relates to the technical field of fan production equipment, and in particular to a positioning device and a feeding device comprising the same. Background Art

[0002] The production of electric fan blades requires installing a sleeve in the mold cavity and then injection molding. Currently, an automatic loader is commonly used in production to complete the automated production of sleeve loading in conjunction with a pneumatic clamp. However, the loader does not have a positioning function. When the pneumatic clamp is used to clamp the sleeve and then place it in the positioning shaft for rotational positioning, there is an error in the cylinder positioning, and the pneumatic clamp also has a certain offset when clamping the sleeve. As a result, the pneumatic clamp often cannot place the sleeve into the positioning shaft or directly hits the positioning shaft. This not only causes the produced fan blades to be defective, but also causes damage to the clamp many times, unstable production, and a lot of wasted debugging time. Summary of the Invention

DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0034] like Figure 1 and Figure 2 As shown, the present invention provides a positioning device for accurately positioning a sleeve when it is installed on a positioning shaft, comprising a discharge assembly 1, a feed assembly 2, a receiving assembly 3 and an adjustment assembly 4, wherein:

[0035] The discharge assembly 1 is set at the material taking position, and is used to send the materials to the material taking position after being arranged and sorted once, that is, the sleeves are arranged vertically with the center holes facing upwards;

[0036] The feeding component 2 is movably arranged between the material taking position and the material dropping position, thereby completing the removal of the sleeve from the material taking position and then feeding it to the material dropping position;

[0037] The adjustment component 4 is set in the adjustment position and is used to adjust the position of the sleeve for the second time to ensure the accurate positioning between the sleeve and the mounting shaft;

[0038] The material receiving component 3 is movably arranged between the blanking position and the adjustment position; the material receiving component 3 is used to receive the shaft sleeve at the blanking position, and then move to the position of the adjustment component 4, and use the adjustment component 4 to adjust and shift the shaft sleeve located on the material receiving component 3 so that the shaft sleeve and the mounting shaft are accurately positioned.

[0039] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, as an optional embodiment of the present invention, the discharge assembly 1 includes a workbench 11 and a feeding vibration plate 12 arranged on the workbench 11, and the material taking position is a discharge port opened on the top side wall of the feeding vibration plate 12, and the material is adjusted and arranged for the first time in the feeding vibration plate 12.

[0040] like Figure 1 、 Figure 3 and Figure 7 As shown, it should be noted that the workbench 11 and the feed vibration plate 12 are both implemented using products in the prior art. There is a spiral arrangement track in the feed vibration plate 12. When the feed vibration plate 12 vibrates, the sleeves in the plate are vibrated into the track and move upward. The vertically arranged sleeves enter the feeding assembly 2 through the discharge port and are transported. The horizontal sleeves that are not well arranged leak back into the plate through the leakage port on the upper side of the vibration plate. It should be noted that since the sleeves are cylindrical in structure and their height is greater than their diameter, when they are vertical, that is, when the center hole is facing upward, they will not leak out through the leakage port. When they are horizontal, the specifications of the leakage port are compatible with the specifications of the sleeve diameter, so that the sleeves that are not well arranged will leak out from the leakage port for rearrangement and then be transported upward. The working principle introduced above is the working principle of the existing feed vibration plate 12, which will not be elaborated on here.

[0041] like Figure 1 and Figure 4 As shown, further, the discharge component 1 also includes a low material level sensor 7 and an alarm component 8. The low material level sensor 7 is arranged in the feeding vibration disk 12. Specifically, the low material level sensor 7 is a multi-circle infrared sensing optical fiber arranged along the circumferential direction of the feeding vibration disk 12. When the shaft sleeve is too little and the infrared sensing optical fiber is exposed, the system determines that the material is less and needs to be replenished in time; the alarm component 8 is installed on the workbench 11 and is electrically connected to the low material level sensor. Furthermore, the alarm component is an alarm light that can display sound and light. It is electrically connected to the low material level sensor through the PLC control module. When the low material level sensor senses that the shaft sleeve is too little, it will send a signal to the PLC control system, and the PLC control system will send a signal to the alarm light to make the alarm light emit an sound and light alarm.

[0042] As an optional embodiment of the present invention, the feeding assembly 2 includes a linear vibrator 21, a pushing cylinder 22, a pushing plate 23 and a material belt 24. One end of the linear vibrator 21 is located at the material taking position, and the other end is located at the top of the pushing plate 23. The linear vibrator 21 is a product in the prior art. The upright shaft sleeve enters the linear vibrator 21 through the top of the feed vibration disk 12 and is transported to the material taking position. The bottom of the pushing plate 23 is fixed on the workbench 11 through a supporting structure, and the top surface of the pushing plate 23 is located at the material taking position. At the lower end of the outlet of the linear vibrator 21, the sleeve is pushed out of the linear vibrator 21 and onto the pushing plate 23. Furthermore, the pushing plate 23 is provided with a blanking port corresponding to the blanking position. The specification of the blanking port can be larger than the diameter of the sleeve or equal to the diameter of the sleeve. When the sleeve is pushed to the blanking port position, the sleeve will fall into the receiving assembly 3 below through the blanking port under the action of gravity; the pushing cylinder 22 is connected to the material belt 24, and can drive the material belt 24 to move back and forth between the end of the linear vibrator 21 and the blanking port.

[0043] Furthermore, the material-carrying member 24 includes a first baffle 241, a second baffle 242 and a first detection member 243 arranged side by side. The first baffle 241 is blocked at the end of the linear vibrator 21, and the pushing cylinder 22 is connected to the first baffle 241. Specifically, the first baffle 241 is an L-shaped structure, with a first side connected to the pushing cylinder 22, and a lower surface of the second side flush with the surface of the workbench 11, and an outer wall surface attached to the outlet of the linear vibrator 21, so that when the first baffle 241 moves relative to the linear vibrator 21, the shaft sleeve located in the vibrator cannot fall out because it is close to the vibrator outlet, and the second baffle 242 is fixed on one side of the port of the linear vibrator 21. Specifically, the second baffle 242 is connected to the end of the pushing plate 23, and there is a gap between the second baffle 242 and the first baffle 241 to form a conveying track; the first baffle 241 and the second baffle 242 are connected. The distance between the two baffles 242 is smaller than the material specifications, that is, the distance between the first baffle 241 and the second baffle 242 is smaller than the diameter of the sleeve. The first baffle 241 is also provided with an inwardly recessed slot 244 for accommodating the material. When the slot 244 moves to the outlet position of the linear vibrator 21, the sleeve can automatically fall into the slot 244. Then, the pushing cylinder 22 extends to drive the first baffle 241 to move. At this time, the sleeve is stuck in the slot 244 and blocked by the second baffle 242 so that it will not fall out. The sleeve moves along the surface of the pushing plate 23 along the conveying track formed between the first baffle 241 and the second baffle 242. When it moves to the drop-out port, the sleeve falls into the material receiving assembly 3 below under the action of gravity. The first detection member 243 is provided on a side wall of the slot 244. Specifically, the first detection member 243 is a photoelectric sensor switch. A fixed conveying track is formed between the first baffle 241, the slot 244, and the second baffle 242 to facilitate the movement of the sleeve.

[0044] Furthermore, the feed assembly 2 includes a limit switch 245 disposed on the push plate 23, corresponding to the position of the material dropout opening. When the first edge of the first baffle 241 reaches the limit switch 245, and the sleeve in the retaining groove 244 is positioned directly above the material dropout opening, the limit switch 245 sends a signal to the PLC control module to inform it that the material has arrived, and the PLC control module controls the push cylinder 22 to stop extending.

[0045] As an optional embodiment of the present invention, the material receiving assembly 3 includes a base body 31, a positioning guide column 32, a material receiving cylinder 33 and a second detection component 34. The second detection component 34 is arranged on the second baffle 242 and is located below the blanking port; the base body 31 is movably connected to the workbench 11 through the material receiving cylinder 33, and the positioning guide column 32 is installed on the base body 31. When the material receiving assembly 3 moves to the blanking position, the positioning guide column 32 is located below the blanking port, and the material is automatically inserted into the positioning guide column 32 through the blanking port under the action of gravity.

[0046] Specifically, the second detection member 34 is a photoelectric sensor switch, which is used to determine whether the sleeve falls into the material receiving component 3.

[0047] Specifically, a positioning platform for supporting and limiting the material is provided at the bottom of the positioning guide column 32. This platform is larger than the positioning guide column 32. A guide portion, smaller than the material cavity, is provided at the top of the positioning guide column 32. It should be further noted that the guide portion is smaller than the sleeve cavity to provide initial support when the sleeve is not inserted into the positioning guide column 32. It should be noted that when the sleeve is inserted into the guide portion but not into the positioning guide column 32, the top of the sleeve should be below the bottom surface of the push plate 23 to prevent interference between the sleeve and the push plate 23 when the receiving cylinder 33 is extended or retracted.

[0048] Furthermore, when the material cavity is non-circular, such as when the sleeve cavity is D-shaped, the shape of the guide part is the same as the shape of the material cavity, that is, the cross-section of the guide part is also D-shaped, and the guide part is a structure with increasing specifications, with the top specification being the smallest and the bottom specification being the same or similar to the specification of the positioning guide column 32, and the positioning guide column 32 is a circular cylindrical structure.

[0049] As a further optional embodiment of the present invention, the adjustment assembly 4 includes an adjustment cylinder 41, a turntable 42, an adjustment tube 43 and a third detection component 44. The third detection component 44 is fixed on the base body 31. Specifically, the third detection component 44 is a photoelectric sensor switch; the adjustment cylinder 41 is transmission-connected to the turntable 42, the adjustment tube 43 is arranged on the side wall of the turntable 42, and the end is contact-connected with the positioning guide column 32. The adjustment tube 43 is made of flexible and deformable material.

[0050] Furthermore, the turntable 42 is arranged horizontally, and the adjustment cylinder 41 is a rotary cylinder capable of driving the turntable 42 to rotate horizontally. Two adjustment tubes 43 are symmetrically arranged on opposite side walls of the turntable 42. Furthermore, the adjustment tubes 43 are made of rubber hoses. During use, the rotating rubber hoses contact the sleeves located on the guide portion or the positioning guide column 32. The rotation of the rubber hoses drives the sleeves to rotate, thereby adjusting the sleeves so that the D-shaped hole in the sleeves aligns with the guide portion and the positioning guide column 32.

[0051] The present invention provides a loading device, which includes a workbench 11 and a positioning device arranged on the workbench 11 .

[0052] Furthermore, anti-vibration feet 5 and universal casters 6 are provided at the bottom of the workbench 11 .

[0053] It should be noted that the universal casters 6 and the anti-vibration feet 5 are both implemented using products in the existing technology, and will not be described in detail here.

[0054] Furthermore, the vibration frequency of the feeding vibration plate 12 and the linear vibrator 21 can be adjusted; the installation position of the pushing cylinder 22, the receiving cylinder 33 and the adjustment cylinder 41 can be adjusted, and the specific adjustment method is to select different installation positions during installation; the number of rotations and speed of the turntable can be adjusted.

[0055] The positioning device provided by the present invention arranges and sorts the materials for the first time by setting a discharge component, so that all the materials are arranged in the same direction and are fed into the feeding component. The feeding component transports the arranged materials to the receiving component at the drop position. After the receiving component completes the material receiving action, it moves to the adjustment component and performs a second arrangement through the adjustment component, so that the materials and the positioning guide are completely aligned, thereby achieving precise positioning between the materials and the components to be installed. The structure is simple and the debugging is convenient. The present invention automatically sorts the shaft sleeves through the feeding vibration plate, pushes the shaft sleeves along the fixed track in the conveying component to the positioning guide column in the receiving component, and positions the direction of the D-shaped hole of the shaft sleeve by turning the rubber hose. The track pushing method replaces the original finger cylinder clamping the shaft sleeve to move it to the positioning shaft, and the turning of the adjustment tube replaces the original rotating finger cylinder positioning the shaft sleeve, which simplifies the equipment structure, reduces the difficulty of debugging and maintenance, and reduces the scrap rate.

[0056] The feeding equipment provided by the present invention is mainly composed of an electrical control system, a feeding vibration plate, a linear vibrator, a turntable with a rubber hose, a cylinder moving mechanism, a workbench, etc. The equipment is required to be simple to operate and have stable performance.

[0057] like Figure 8As shown, the electrical control system is controlled by a PLC program, and the material arrival and machine operation status are detected by a photoelectric sensor switch, and the information is reflected in real time; when in use, 1,200 fan blade sleeves can be added to the feeding vibration plate at one time, and the feeding vibration plate automatically arranges the fan blade sleeves; the material is sent to the designated position through the feeding vibration plate and the linear vibrator. When there is a jam or blockage in the middle, the infrared sensor in the feeding vibration plate can automatically detect it and automatically sound an alarm; the pushing cylinder pushes the card slot to push the sleeve to the blanking hole, and the sleeve falls and is covered on the D-type positioning guide column; the receiving cylinder drives the D-type positioning guide column to a position parallel to the turntable of the rubber hose, and the turntable rotates, and the rubber hose moves the sleeve, giving a downward rotating force, so that the sleeve rotates and is stuck in the D-type positioning guide column; it should be noted here that the downward force applied by the rubber hose to the sleeve is composed of the downwardly mounted turntable, the rubber hose and the gravity of the sleeve itself. After the sleeve is positioned, the turntable stops. After the robot removes the fan sleeve, the device automatically pushes the sleeve through infrared detection and positions the next sleeve, repeating the cycle. Specifically, in this embodiment, the position where the fan sleeve is to be picked up by the robot is 1.4 meters above the ground. The entire device has four universal casters with brakes for mobile movement and four anti-vibration feet 6 that can be raised and lowered for support.

[0058] The feeding vibration plate in the feeding equipment of the present invention can load about 1,200 sleeves at a time; a minimum capacity warning line is provided in the feeding vibration plate. When the fan shaft sleeve is lower than the lower limit of the warning line, the equipment will automatically sound an alarm through infrared sensing to remind employees to add sleeves; when the robot takes the sleeve, a position for the robot clamp should be reserved at the fan shaft sleeve standby station.
