Description

Technical Field

[0001] The invention relates to the field of mechanical technology, in particular to an inner star wheel feeding device. Background Art

[0002] The inner star wheel is one of the important parts of the automobile constant velocity joint.

[0003] For the existing inner star wheel blanks, before fine processing, they are usually randomly stacked in a workpiece basket. Based on this workpiece placement situation, at present, human wisdom and consciousness are needed to complete sequential operations such as taking the inner star wheel blanks, adjusting the posture of the inner star wheel blanks, and placing the inner star wheel blanks into the inner star wheel workpiece processing equipment.

[0004] In order to reduce labor costs, collaborative robots have been introduced in production practice to replace manual labor to carry out the picking and placing operations of the inner star wheel blanks. After the inner star wheel blanks are picked up, they are placed in the existing inner star wheel workpiece processing equipment for further processing.

[0005] However, when the existing collaborative robots are working, they cannot replace human wisdom and consciousness. The mechanical arms of the collaborative robots cannot identify the front and back sides of the inner star wheel blanks with the correct posture, so the picking direction of the inner star wheel blanks is prone to errors, which will cause the inner star wheel blanks to be placed in the existing inner star wheel workpiece processing equipment with the wrong orientation (for example, some inner star wheel blanks are facing up, some are facing up, and some are even placed at an angle). That is, when the collaborative robots take and place the inner star wheel blanks, there is a problem of wrong orientation placement.

[0006] If the collaborative robot places the inner star wheel blank in the wrong orientation, it will cause the workpiece to be installed in reverse, and the inner star wheel workpiece processing equipment to crash, which will lead to the risk of long-term equipment shutdown, seriously affecting the overall product production efficiency and increasing production costs.

[0007] Therefore, there is an urgent need to develop a device that can cooperate with the robotic arm of the existing collaborative robot so that the robotic arm of the existing collaborative robot can pick up and place the inner star wheel blank placed in the correct orientation, thereby ensuring that the collaborative robot places the inner star wheel blank in the correct posture (specifically orientation) into the existing inner star wheel workpiece processing equipment.

[0067] See also Figures 1 to 6 , the present invention provides an inner star wheel feeding device, comprising a device main support 100;

[0068] The upper part of the main support of the device is fixedly provided with a first supporting frame 1 and a second supporting frame 9;

[0069] The second supporting frame 9 is located directly above the first supporting frame 1;

[0070] Wherein, for the first supporting frame 1, a first supporting plate 2 (such as an iron plate) distributed laterally is fixedly arranged on the top of the first supporting frame 1;

[0071] A second electric cylinder 10 distributed laterally is fixedly arranged on the top of the first support plate 2;

[0072] The slider at the top of the second electric cylinder 10 is connected to the bottom of the second support plate 3 distributed longitudinally;

[0073] A longitudinally distributed first electric cylinder 4 is fixedly arranged on the top of the second support plate 3;

[0074] An L-shaped workpiece push plate 26 is installed on the slider at the top of the first electric cylinder 4;

[0075] Wherein, for the second supporting frame 9, a plurality of pairs of optical axis bases 13 are fixedly arranged on the top of the second supporting frame 9;

[0076] The rear end top of the second support frame 9 has a rear aluminum profile bracket 52 distributed laterally;

[0077] Each pair of optical axis bases 13 are fixedly arranged at the top of the front frame of the second support frame 9 and the top of the rear aluminum profile bracket 52 symmetrically front and rear;

[0078] A pair of first optical axes 15 distributed longitudinally are mounted on each pair of optical axis bases 13;

[0079] The front end of each pair of first optical axes 15 is covered with a same slide block 16;

[0080] Each pair of first optical axes 15 are spaced apart in the transverse direction;

[0081] Each pair of first optical axes 15 is combined together to form a workpiece slideway (each pair of first optical axes 15 serves as the left and right sides of the workpiece slideway respectively);

[0082] The workpiece slideway formed by each pair of first optical axes 15 is used to place a plurality of inner star wheel blanks 17 that need to be loaded, and the plurality of inner star wheel blanks 17 are located directly behind the slideway push blocks 16 of the pair of first optical axes 15;

[0083] It should be noted that, for the present invention, in order to avoid disorderly and random stacking of the inner star wheel blanks 17, a workpiece slide (composed of two first optical axes 15) with low friction is designed according to the shape of the inner star wheel blanks 17, and multiple inner star wheel blanks 17 can be arranged in order on the workpiece slide and arranged on the slide according to the required posture (for example, the front side faces forward, the back side faces backward, and they are placed flat axially).

[0084] The second electric cylinder 10 is used to drive the first electric cylinder 4 to move left and right in the lateral direction;

[0085] The first electric cylinder 4 is used to move the workpiece push plate 26 on its slider to the front side of the slide block 16 on the pair of first optical axes 15 when it is necessary to push multiple inner star wheel blanks 17 on the pair of first optical axes 15, and then push the slide block 16 backward in the longitudinal direction through the workpiece push plate 26.

[0086] In the present invention, specifically, the top surface height of the workpiece push plate 26 is lower than the bottom surface height of the first optical axis 15 and higher than the bottom surface height of the slide block 16.

[0087] In the present invention, specifically, the longitudinal cross-sectional shape of the slide block 16 is L-shaped.

[0088] In the present invention, specifically, the preset length part at the front end of the first optical axis 15 is a thick diameter part 150;

[0089] The diameter of the thick diameter part 150 is larger than the diameter of other parts of the first optical axis 15 and larger than the diameter of the through hole in the slide block 16 for passing the first optical axis 15.

[0090] Therefore, based on the above design, the slide block 16 can be restricted at the preset position at the front end of the first optical axis 15.

[0091] In the present invention, specifically, the first support frame 1 and the second support frame 9 are of a rectangular structure with a hole in the middle.

[0092] In the present invention, specifically, at the front and rear ends of the bottom of the second support plate 3, one first support block 24 is fixedly arranged vertically;

[0093] On the opposite sides of the two first support blocks 24, one roller 27 is pivotally connected (i.e., rotatably connected);

[0094] The bottoms of the two rollers 27 are respectively in contact with the top of the front frame and the top of the rear frame of the first support frame 1.

[0095] Specifically, at the rear end of the bottom of the second support plate 3, a sensor detection block 28 is further arranged vertically;

[0096] The sensor detection block 28 is located in front of the sensor bracket 11 and behind the second electric cylinder 10.

[0097] Specifically, each roller 27 is connected to the first support block 24 through a bolt 23 (as a pivot shaft).

[0098] It should be noted that through the design of the roller 27, the load-bearing of the first electric cylinder 4 can be divided into grades.

[0099] In specific implementation, the two first support blocks 24 are also fixed to the bottom of the second support plate 3 through an angle iron 25 respectively (for example, by welding one end of the angle iron to the first support block 24 and the other end to the bottom of the second support plate 3).

[0100] In specific implementation, the first support frame 1 is also equipped with a transversely distributed sensor bracket 11;

[0101] The sensor bracket 11 is located directly behind the first support plate 2;

[0102] A plurality of position sensors 29 (eg, proximity sensors, such as existing ultrasonic proximity switches) are installed on the sensor bracket 11 at equal intervals.

[0103] In a specific implementation, the plurality of position sensors 29 are respectively located directly below the plurality of first optical axes 15 .

[0104] It should be noted that, in specific operation, when the position sensor 29 detects that an object (such as the sensor detection block 28) is approaching a preset distance range, it sends a trigger stop signal to the second electric cylinder 10 to stop the second electric cylinder from moving, and sends a trigger start signal to the first electric cylinder to trigger the movement of the slider on the first cylinder, thereby allowing the workpiece push plate to work. When the preset workpiece push plate completion time period (such as 10 seconds) is reached, the second electric cylinder resumes moving and moves to an adjacent position. The position sensor 29 at the adjacent position continues to trigger the work, triggering the first electric cylinder and the second electric cylinder to perform the above work, and repeats the process, thereby completing the pushing and loading operations of multiple pairs of inner star wheel blanks 17 on the first optical axis.

[0105] In the present invention, in a specific implementation, the inner star wheel blank 17 is axially placed on the first optical axis 15 .

[0106] In the present invention, in specific implementation, a front aluminum profile bracket 51 distributed laterally is fixedly provided on the top of the front frame of the second support frame 9;

[0107] A first fixing block 12 (for example, an iron block fixed by welding) is fixedly provided at the left and right ends of the top of the front aluminum profile bracket 51;

[0108] The tops of the two first fixing blocks 12 are fixed with transversely distributed metal baffles 6;

[0109] Among them, a plurality of magnets 14 (not limited to two) are installed on the front end surface of the slide push block 16;

[0110] The metal baffle plate 6 is used to form a magnetic attraction with the magnet 14 on the slideway push block 16 .

[0111] It should be noted that, for the present invention, through the setting of the magnet 14, when the workpiece push plate 26 on the slider of the first electric cylinder 4 no longer pushes the slide push block 16, the slide push block 16 made of the magnetic metal material can be magnetically adsorbed, thereby resetting the slide push block 16, so that the slide push block 16 moves along the first optical axis 15 toward the magnetic metal baffle 6.

[0112] In a specific implementation, the installation height of the metal baffle 6 is the same as the installation height of the magnet 14 on the slideway push block 16 .

[0113] In the present invention, in a specific implementation, a second fixing block 20 (for example, an iron block fixed by welding) is fixedly provided at the left and right ends of the top of the rear frame of the second supporting frame 9;

[0114] The two second fixing blocks 20 are respectively provided with optical axis plugging holes;

[0115] The left and right ends of the transversely distributed second optical axis 21 are respectively plugged into the optical axis plugging holes of the two second fixing blocks 20;

[0116] A plurality of discharge channels 19 tilted backward are fixedly disposed at the top of the second optical axis 21 at positions corresponding to the rear ends of each first optical axis 15;

[0117] The multiple discharge channels 19 are parallel to each other and have the same height;

[0118] A third support plate 8 is fixedly provided (for example, welded) on the rear side of the rear frame of the second support frame 9;

[0119] A transversely distributed smooth strip 7 is fixedly arranged (for example, welded) on the rear side of the third support plate 8;

[0120] The height of the smooth bar 7 gradually increases from left to right.

[0121] In a specific implementation, the front and rear sides of the flow strip 7 are respectively provided with vertically distributed guard plates.

[0122] In specific implementation, the height of the highest point of the flow strip 7 is lower than the height of the rear end discharge port of the discharge channel 19 .

[0123] It should be noted that, through the provision of the smooth strip 7, the inner star wheel blank 17 can be slid out.

[0124] In a specific implementation, the center point of the first optical axis 15 and the center point of the front end feed port of the discharge channel 19 are located on the same axial straight line.

[0125] In specific implementation, a vertically distributed column 22 is fixedly provided on the left side of the left frame and the right side of the right frame of the second supporting frame 9;

[0126] The tops of the two uprights 22 are connected to the left and right ends of a pull rope 18;

[0127] The pull rope 18 is located just above the front end feed port of the discharge channel 19 .

[0128] It should be noted that the bottom of the pull rope 18 is in contact with the top surface of the inner star wheel blank 17 placed on the first optical axis 15 .

[0129] It should be noted that the arresting rope is located above the outlet of the workpiece slideway and is used to adjust the posture of the inner star wheel blank 17. The arresting rope can not only play a blocking role, but also can make the inner star wheel blank 17 fall backward smoothly without jamming.

[0130] It should be noted that, in the present invention, the first electric cylinder 4 and the second electric cylinder 10 can be two low-thrust electric cylinders (within 75N). By cross-mounting them, they can not only move the workpiece push plate 26 to any point within the specified range, but also the workpiece push plate 26 is metal iron and can also be attracted to the magnet 14 on the slide push block 16.

[0131] In a specific implementation, the first electric cylinder 4 and the second electric cylinder 10 are existing slider-type electric cylinders, for example, they may be slider-type electric cylinders of model RCP6-SA6C-WA-42P-12-500-P3-M produced by IAI Corporation (Shanghai).

[0132] In the present invention, a metal baffle plate 6 is installed at the front end of the workpiece slideway composed of each pair of first optical axes 15. The metal baffle plate 6 can not only meet the positioning requirements, but also allow the workpiece push plate and the slideway push block 16 to be automatically separated under its obstruction (the workpiece push plate moves forward with the slider of the first electric cylinder, and the slideway push block 16 is blocked by the metal baffle plate 6, wherein the rear side of the slideway push block 16 protrudes backward from the rear side surface of the front aluminum profile bracket 51 and the rear side surface of the front frame of the second support frame 9).

[0133] In the present invention, the first supporting frame and the second supporting frame are both frames composed of four hollow square tubes, which play a supporting role.

[0134] Each pair of first optical axes 15 is used to support the inner star wheel blank 17 thereon;

[0135] The workpiece push block 26, driven by the first electric cylinder 4, pushes the slideway push block 16 on the first optical axis 15, thereby further pushing the plurality of inner star wheel blanks 17 on the first optical axis 15 where the slideway push block 16 is located to move backward.

[0136] In order to more clearly understand the technical solution of the present invention, the working process of the present invention is described below.

[0137] The first step is to manually load a plurality of inner star wheel blanks 17 into the plurality of pairs of first optical axes 15 of the present invention in advance;

[0138] See also Figure 1 As shown, in order to avoid disorderly and random stacking of the inner star wheel blanks 17, multiple inner star wheel blanks 17 are arranged in order on the workpiece slideway and arranged on the slideway according to the required posture (for example, the front side faces forward, the back side faces backward, and they are placed flat axially).

[0139] In the second step, the position of the first electric cylinder 4 is moved by the second electric cylinder 10. After the first electric cylinder 4 is moved to the front lower part of the slideway push block 16 on the pair of first optical axes 15, the inner star wheel blank 17 is pushed backward along the first optical axis 15 by the workpiece push plate 26 installed on the slide block of the first electric cylinder 4.

[0140] The third step is to adjust the positioning posture of the inner star wheel blank 17 (i.e., from axially flat placement, with the front side in front and the back side in the back, to vertical placement, with the front side on top and the back side on the bottom) by cooperating with the pull rope 18, the slideway 19 and the smooth strip 7, and then slide down along the smooth strip 7;

[0141] In the fourth step, when the inner star wheel blank 17 slides down to the lowest point of the smooth bar 7, or onto the stopper connected to the lowermost opening of the smooth bar 7 (on the stopper, an inner star wheel blank accommodating groove is set, the groove is semicircular or three-quarter circular, and the opening of the groove faces the smooth bar 7, that is, the incoming direction), the mechanical arm of the existing collaborative robot can sequentially grab multiple inner star wheel blanks with the same required orientation (that is, the correct orientation placed in advance, that is, the inner star wheel blank 17 placed vertically up and down with the front side facing up), and then put them into the existing inner star wheel workpiece processing equipment in turn, and the inner star wheel workpiece processing equipment will perform processing operations.

[0142] It should be noted that the grabbing and placing operations of objects by the mechanical arms of existing collaborative robots are conventional technical means of existing collaborative robots and are existing technologies, which will not be elaborated here.

[0143] In terms of specific implementation, the existing collaborative robot can be an existing four-axis manipulator, which is an existing manipulator capable of high-speed pick-and-place operations and is an existing mature technical equipment.

[0144] In terms of specific implementation, the existing collaborative robot, for example, a small assistant robot (i.e., a collaborative robot) of model JAKA ZU 12 produced by Shanghai JAKA Robot Technology Co., Ltd. can be used.

[0145] Compared with the prior art, the inner star wheel feeding device provided by the present invention has the following beneficial effects:

[0146] 1. By utilizing the present invention, the inner star wheel blank is loaded. The present invention and the existing collaborative robot complete the operation combination, which not only eliminates the reverse installation problem caused by the incorrect placement of the inner star wheel blank, but also eliminates the collision problem caused by the inadequate placement of the inner star wheel blank, thus avoiding long-term equipment repairs;

[0147] 2. By applying the present invention, the collaborative robot can pick up and place the inner star wheel blank in the correct orientation, eliminating misoperation;

[0148] 3. The present invention adopts a low-thrust device to prevent the potential safety hazard of pinching people.

[0149] To sum up, compared with the prior art, the inner star wheel loading device provided by the present invention has a scientific structural design, and can cooperate with the mechanical arm of the existing collaborative robot, so that the mechanical arm of the existing collaborative robot can pick up and place the inner star wheel blank in a specified orientation (i.e., the front side facing up and the back side facing down), thereby ensuring that the collaborative robot places the inner star wheel blank in the correct posture (specifically the correct orientation, i.e., the specified orientation) into the existing inner star wheel workpiece processing equipment, which has great production practical significance.

[0150] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
