Description

Technical Field

[0001] This utility model belongs to the field of barcode scanning technology, specifically relating to a posture self-detection angular barcode scanning device. Background Technology

[0002] During gear assembly, the first step is to scan the marking code on the outer circumference of the gear with a barcode scanner to obtain its information and send it to the control unit. Then, the robot arm picks up the gear and places it on the machine tool for subsequent assembly. However, after scanning, the gear is usually directly sent to the machine tool without any position detection measures, so it is impossible to align the gear to ensure the required position. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem that in the prior art, after scanning, the material is generally directly transported to the machine tool without any posture detection measures, so it is impossible to align the gears to ensure the position requirements of the gears. Here, a posture self-detection angular scanning device is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a posture self-detection angular scanning device, comprising:

[0005] A clamping assembly for holding the gear and rotating it;

[0006] The barcode scanning component includes a barcode scanner with an oscillating setting;

[0007] The device includes a position and orientation detection component located on the unloading path of the gear, comprising a probe holder, a probe for contacting the outer peripheral surface of the gear and slidably mounted on the probe holder, a sensing element located on the probe moving path, and a reset elastic element for driving the probe to reset.

[0008] Furthermore, the scanning assembly also includes a first rotary drive mechanism for driving the barcode scanner to rotate and a linear reciprocating drive mechanism for driving the first rotary drive mechanism to translate.

[0009] Furthermore, the clamping assembly includes a chuck for clamping the gear and a second rotary drive mechanism for driving the chuck to rotate.

[0010] Furthermore, the chuck includes a base and a plurality of jaws that are spaced apart circumferentially along the base and can move closer to or further away from each other, each jaw having a plurality of clamping steps formed radially.

[0011] Furthermore, the clamping assembly also includes a transition plate connected to the output end of the second rotary drive mechanism and a mounting plate for mounting the chuck, the mounting plate protruding radially from the chuck and fixed to the transition plate.

[0012] Furthermore, the substrate is formed with a clamping cavity into which the shaft of the gear extends.

[0013] Furthermore, the pose detection component also includes a laser detection mechanism located at the front end of the probe along the gear feeding path.

[0014] Furthermore, a sliding seat is fixed on the probe holder for the probe to pass through, and a protruding ring is formed on the radially protruding end of the probe away from the sliding seat. One end of the reset elastic member abuts against the protruding ring, and the other end abuts against the sliding seat.

[0015] Furthermore, the mounting plate protrudes towards the chuck to form an upper positioning protrusion for positioning the chuck, and the mounting plate protrudes towards the transition plate to form a lower positioning protrusion for positioning both.

[0016] Furthermore, the probe has a radially protruding end near the sensing element, which is formed with a limiting protrusion for limiting the probe's travel.

[0017] The beneficial effects of this utility model are: this utility model uses a swing-mounted barcode scanner to meet the barcode scanning requirements of gears of different sizes, and uses an elastically mounted probe in conjunction with a sensing element to detect the gear position after scanning, thereby improving the positional accuracy of the gear.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0033] like Figure 1 and Figure 2 As shown, a self-detecting angular scanning device is used to scan the identification code on the outer peripheral surface of a gear 5. The gear 5 includes a cylindrical gear or a bevel gear, etc. The angular scanning device includes a base 4, on which a clamping assembly 1, a scanning assembly 2 and a pose detection assembly 3 are installed. The scanning assembly 2 and the pose detection assembly 3 are arranged around the clamping assembly 1.

[0034] The clamping assembly 1 is used to clamp the gear 5 and drive it to rotate. When scanning, the clamping assembly 1 is first used to clamp the gear 5, and then the gear 5 is driven to rotate so that the identification code on it faces the scanning assembly 2.

[0035] The barcode scanning component 2 includes a barcode scanner 201 that is oscillating, so that it can scan gears 5 of different sizes;

[0036] The pose detection component 3 is located on the unloading path of the gear 5. After the gear 5 has been scanned, it detects the pose of the gear 5 grasped by the robot arm, ensuring the gear 5 can maintain its pose and proceed to the next process. The pose detection component 3 includes a probe base 301, a probe 302 that contacts the outer peripheral surface of the gear 5 and is slidably mounted on the probe base 301, a sensing element 303 located on the moving path of the probe 302, and a reset elastic element 304 for resetting the probe 302. The reset elastic element 304 can be a spring, and the sensing element 303 can be, but is not limited to, a proximity switch. The surface includes tooth grooves and tooth tips. After the robot arm drives the gear 5 on it to the position of the probe 302, when the tooth tip is aligned with the probe 302, the tooth tip will push the probe 302 to move. At this time, the reset elastic element 304 is compressed. The sensing element 303 can sense the movement and position of the probe 302 and transmit the signal to the control unit. When the tooth groove is aligned with the probe 302, the probe 302 can extend into the tooth groove. At this time, the position of the probe 302 does not change. Therefore, the current posture of the gear 5 can be determined according to whether the probe 302 moves. When the posture is different from the initial program setting, it can be corrected to achieve the requirement of uniform posture of the gear.

[0037] In some examples, the scanning assembly 2 further includes a first rotary drive mechanism 202 for rotating the barcode scanner 201 and a linear reciprocating drive mechanism 203 for translating the first rotary drive mechanism 202. The first rotary drive mechanism 202 may be, but is not limited to, a swing cylinder, a motor, etc., and the linear reciprocating drive mechanism 203 may be, but is not limited to, a linear module, a cylinder, etc. The first rotary drive mechanism 202 can drive the barcode scanner 201 to rotate to meet the scanning requirements of gears 5 of different sizes, and the linear reciprocating drive mechanism 203 can increase the swing range of the barcode scanner 201, further improving its applicability.

[0038] In some examples, the scanning assembly 2 includes a chuck 101 for holding the gear 5 and a second rotary drive mechanism 102 for driving the chuck 101 to rotate. The second rotary drive mechanism 102 may be a motor, which can drive the gear 5 on the chuck 101 to rotate so that the identification code on it faces the barcode scanner 201.

[0039] In some examples, the chuck 101 includes a base 1011 and a plurality of jaws 1012 that are spaced apart circumferentially along the base 1011 and can move closer to or further away from each other. Each jaw 1012 has a plurality of clamping steps 1012a formed radially. The number of clamping steps 1012a on each jaw 1012 can be, but is not limited to, one, two or three, etc. The clamping steps 1012a further improve the applicability of the jaws 1012.

[0040] In some examples, the clamping assembly 1 further includes a transition plate 103 connected to the output end of the second rotary drive mechanism 102 and a mounting plate 104 for mounting the chuck 101. The mounting plate 104 protrudes radially from the chuck 101 and is fixed to the transition plate 103. The fixing method can be a bolt connection, which passes through the mounting plate 104 and the transition plate 103 from top to bottom. When the chuck 101 needs to be disassembled, the operator can simply loosen the bolts. This avoids the situation in the prior art where the second rotary drive mechanism 102 is only connected to the chuck 101 through the transition plate 103, and the bolts can only be screwed in from bottom to top, which requires bending over to the bottom of the transition plate 103 to operate when disassembling the chuck 101, making the operation extremely inconvenient.

[0041] In some examples, the base 1011 is formed with a clamping cavity 1011a into which the shaft of the gear 5 extends. The gear 5 can be a hollow structure as shown in the figure or a solid structure with a shaft. The clamping cavity 1011a allows the shaft to extend into, which further improves the applicability of the chuck 101.

[0042] In some examples, the pose detection component 3 also includes a laser detection mechanism 305 located at the front end of the probe 302 along the feeding path of the gear 5. It can be a laser rangefinder. After the probe 302 detects the posture of the gear 5 once based on the different distances between the laser rangefinder and the tooth tip and tooth groove, the probe 302 performs a second detection on the posture of the gear 5. The orientation detected by the laser detection mechanism 305 and the orientation detected by the probe 302 can both be the tooth tip or tooth groove, but the two detection orientations should be consistent. When the orientation detected by the laser detection mechanism 305 is different from the initial setting, the second rotation drive mechanism 102 can drive the gear 5 to rotate slightly to perform posture correction.

[0043] In some examples, a sliding seat 306 for the probe 302 to pass through is fixed on the probe seat 301, and a protruding ring 3021 is formed radially at one end of the probe 302 away from the sliding seat 306. The protruding ring 3021 and the probe 302 can be integrally formed or threaded onto a nut on the probe 302. One end of the reset elastic member 304 abuts against the protruding ring 3021, and the other end abuts against the sliding seat 306. An oil-free bushing 307 is installed between the inner peripheral wall of the sliding seat 306 and the outer peripheral wall of the probe 302.

[0044] In some examples, the mounting plate 104 protrudes toward the chuck 101 to form an upper positioning protrusion 1041 for positioning the chuck 101, and the mounting plate 104 protrudes toward the transition plate 103 to form a lower positioning protrusion 1042 for positioning both, and the inner peripheral wall of the transition plate 103 forms an annular groove for the lower positioning protrusion 1042 to be engaged.

[0045] In some examples, the probe 302 has a radially protruding limiting protrusion 3022 at one end near the sensing element 303 to limit the travel of the probe 302, and the probe seat 301 has a through hole for the probe 302 to pass through, and the limiting protrusion 3022 is used to abut against the through hole.

[0046] Working principle:

[0047] First, the chuck 101 clamps the gear 5. The second rotary drive mechanism 102 drives the gear 5 to rotate so that the identification code on it rotates towards the barcode scanner 201. At the same time, the first rotary drive mechanism 202 and the linear reciprocating drive mechanism 203 work together to make the scanning direction of the barcode scanner 201 aligned with the identification code for scanning. After scanning is completed, the laser detection mechanism 305 performs a first detection on the position of the gear 5. Then, the robot arm transports the barcode scanner 201 to the next process. During the transport process, it drives the gear 5 it is holding to move towards the probe 302 for a second detection.
