Description

Technical Field

[0001] This application relates to the technical field of jewelry processing, and particularly to a gold wire positioning device for gold jewelry processing. Background Art

[0002] In the field of gold jewelry processing, as a classic ornament, a gold necklace is usually composed of multiple oval gold rings connected in series. The raw materials of these gold rings are cylindrical metal bars or gold wires, with iron inside and gold wrapped outside. During the processing, the iron inside needs to be melted through a chemical reaction and flow out through pre-set small holes to form a hollow gold structure with a higher purity. However, the position of the small holes has an important impact on the aesthetics of the finished gold jewelry. If the small holes are located in the outer ring part of the gold ring, it will not only affect the comfort during wearing, but also damage the overall beauty of the jewelry and reduce its market value. Therefore, during the processing, it is necessary to ensure that the small holes are accurately set in the inner ring part of the gold ring.

[0003] Traditional processing has deficiencies in adjusting the position of the small holes. Due to the diverse specifications of metal bars, different batches and different specifications of gold chains require small hole designs at different positions. In traditional processing, manual adjustment of the small hole positions of metal bars is often relied on, which is not only inefficient, but also difficult to ensure the adjustment accuracy. In addition, manual adjustment is prone to introducing human errors, further affecting the processing quality. Summary of the Invention

Detailed implementation manners

[0032] The following will further describe the present application in detail Figures 1-5 with reference to the attached drawings.

[0033] The embodiment of the present application discloses a gold wire positioning device for gold jewelry processing.

[0034] Refer to Figure 1 And Figure 2A gold wire positioning device for gold jewelry processing includes a machine table 1, a detection seat 2 is arranged on the top of the machine table 1, and an identification device is arranged on the detection seat 2. The identification device includes a scanning identification head 21, and the scanning identification head 21 is electrically connected to an external terminal system. The scanning identification head 21 and the external terminal system use existing graphic visual positioning technology to scan and identify the metal strip passing in front of the scanning identification head 21, and the direction and position of the small hole are determined by an image processing algorithm. A discharge hole 11 is opened on the top side of the machine table 1, and the discharge hole 11 is located below the scanning identification head 21. A feeding drum 31 and a drum driving member 32 for driving the feeding drum 31 to rotate are provided on the top of the seat 2. The rotation axis of the feeding drum 31 extends in the horizontal direction. The drum driving member 32 is a motor. The driving end of the drum driving member 32 is connected to the feeding drum 31. The middle part of the feeding drum 31 is concave, which is convenient for the central transmission of the metal strip. A steering assembly for driving the feeding drum 31 and the drum driving member 32 to turn is also provided on the detection seat 2. The direction of the steering axis of the feeding drum 31 and the drum driving member 32 is perpendicular to the rotation axis of the feeding drum 31 itself.

[0035] When it is necessary to scan and identify the raw materials of the gold chain, the metal bar can be placed on the feeding drum 31, and the drum driving member 32 is started to rotate the feeding drum 31 for transportation, so that the metal bar passes in front of the scanning and identification head 21. The scanning and identification head 21 scans and identifies the metal bar, and determines whether the preset direction and position of the small hole are aligned through the image processing algorithm. During identification, the position of the scanning and identification head 21 is set as the preset position direction. When the scanning and identification head 21 determines that the preset small hole position of the metal bar is not facing the preset direction, the steering component drives the feeding drum 31 and the drum driving member 32 to turn, so that the preset small hole position faces the scanning and identification head 21, thereby accurately aligning with the preset position, reducing errors, facilitating the next step of processing, and improving processing quality.

[0036] The steering assembly includes a feed rack 4 and a steering drive 22. The feed rack 4 is rotatably connected to the detection seat 2. The feed drum 31 is rotatably connected to the feed rack 4. The rotation axis of the feed rack 4 is perpendicular to the rotation axis of the feed drum 31. The rotation axis of the feed rack 4 extends in the vertical direction. The steering drive 22 is a motor. The feed rack 4 is transmission-connected to the driving end of the steering drive 22.

[0037] When the preset small hole position of the metal strip is not facing the preset direction, the steering drive 22 can drive the feeding rack 4 to rotate, so that the metal strip being transported rotates, so that the preset position of the metal strip faces the scanning recognition head 21.

[0038] The detection base 2 is provided with a discharge clamp 23. A discharge roller 231 is rotatably connected to the side wall of the discharge clamp 23. The number of discharge rollers 231 is two and they are symmetrically arranged. The scanning and recognition head 21 is located between the discharge roller 231 and the feeding rotating cylinder 31. A discharge driving member 24 is provided on the side wall of the discharge clamp 23. The discharge driving member 24 is a motor, and the driving end of the discharge driving member 24 is connected to the discharge roller 231. After the metal strip passes through the scanning and recognition head 21, it will continue to move downward and approach the position between the two discharge rollers 231. By making the discharge driving member 24 drive the discharge roller 231 to rotate, the metal strip can be transported downward and discharged. The discharge roller 231 can clamp and pull down the metal strip.

[0039] Refer to Figure 3 , a push plate 12 and a pressure-receiving rod 13 are arranged in the discharge hole 11. A pushing driving member 14 for driving the push plate 12 to approach or move away from the pressure-receiving rod 13 is installed on the hole wall of the discharge hole 11. The pushing driving member 14 is a cylinder, and the driving end of the pushing driving member 14 is connected to the push plate 12. One end of the pressure-receiving rod 13 is connected to the hole wall of the discharge hole 11, and the end of the pressure-receiving rod 13 away from the hole wall of the discharge hole 11 is in an arc-shaped concave state. The side of the push plate 12 close to the pressure-receiving rod 13 is in an arc-shaped convex state. The push plate 12 and the pressure-receiving rod 13 are adapted to each other. The arrangement direction of the push plate 12 and the pushing driving member 14 in the discharge hole 11 is the same as the arrangement direction of the scanning and recognition head 21 on the detection base 2.

[0040] After the metal strip passes through the discharge roller 231, it passes through the space between the push plate 12 and the pressure-receiving rod 13. The pushing driving member 14 can drive the push plate 12 to move closer to the pressure-receiving rod 13. Utilizing the characteristic that the metal strip is relatively soft in hardness, the metal strip is pre-bent with a small arc, so that the position of the preset small hole of the metal strip is located on the inner arc surface of the bend, thus facilitating subsequent identification and processing.

[0041] Refer to Figure 1 And Figure 2 , the rotation axis of the feeding rack 4 is close to the vertical tangent plane on the transportation side of the feeding rotating cylinder 31. A fixed clamping roller 41 is rotatably connected to the feeding rack 4. The number of fixed clamping rollers 41 is two and they are symmetrically arranged. The rotation axis of the fixed clamping roller 41 extends along the vertical direction. A fixed clamping groove 411 for the metal strip to pass through is formed on the roller surface of the fixed clamping roller 41. The horizontal height of the fixed clamping groove 411 is close to the horizontal tangent plane on the top transportation side of the feeding rotating cylinder 31. Since the metal strip before entering the feeding rack 4 for transportation is generally placed at a specific position, the fixed clamping roller 41 and the fixed clamping groove 411 can make the metal strip pass through the fixed clamping roller 41 before being fed by the feeding rotating cylinder 31, so that the metal strip can still be in a horizontal state and approach the feeding rotating cylinder 31 for transportation at different rotation angles of the feeding rack 4 as much as possible, reducing the situation that the position of the metal strip on the feeding rotating cylinder 31 deviates seriously after the feeding rack 4 rotates.

[0042] Refer to Figure 4 AndFigure 5 A plurality of pinching rollers 42 are provided at one end of the feeding rack 4 away from the detection seat 2. The number of pinching rollers 42 is two, and the pinching rollers 42 are symmetrically arranged. The feeding rack 4 is also provided with a pinching driving member 43 for driving the pinching rollers 42 to rotate. The pinching driving member 43 is a motor. The driving end of the pinching driving member 43 is connected to the pinching rollers 42. The fixed pinching roller 41 is located between the pinching rollers 42 and the feeding drum 31. The metal strip passes through the pinching rollers 42 before passing through the fixed pinching rollers 41. The pinching rollers 42 can clamp the metal strip. When passing through, the pinching driving member 43 drives the pinching rollers 42 to rotate and transports the metal strip to the fixed pinching rollers 41. The pinching driving member 43 and the drum driving member 32 jointly control the feeding speed of the metal strip.

[0043] One end of the feeding rack 4 away from the detection seat 2 is slidingly connected to a sliding seat 44. There are two sliding seats 44 and they are symmetrically arranged. The clamping roller 42 is rotatably connected to the sliding seat 44. The clamping driving member 43 is installed on the sliding seat 44. The feeding rack 4 is provided with a sliding driving member 45. The sliding driving member 45 is a cylinder. The driving end of the sliding driving member 45 is connected to the sliding seat 44. The sliding driving member 45 is used to drive the sliding seats 44 to move closer to or away from each other. The feeding rack 4 is also provided with a supporting platform 46 for supporting the metal strip. There are two supporting platforms 46. The clamping roller 42 is located between the two supporting platforms 46.

[0044] Since the clamping and shifting driving member 43 and the rotating drum driving member 32 can jointly control the feeding speed of the metal strip, during feeding, a part of the metal strip can be pre-pulled into between the fixed clamping roller 41 and the clamping and shifting roller 42 by the clamping and shifting driving member 43 and the clamping and shifting roller 42, so that the length of the metal strip between the fixed clamping roller 41 and the clamping and shifting roller 42 is increased. When the feeding rack 4 is rotated, the sliding driving member 45 can be started to make the sliding seats 44 move away from each other, so that the pre-pulled metal strip between the fixed clamping roller 41 and the clamping and shifting roller 42 is pulled out, leaving a rotation space, and trying to avoid the metal strip from being broken before the feeding rack 4 rotates. When the feeding rack 4 rotates, the metal strip is easy to cling to the roller surface of the clamping and shifting roller 42. When the metal strip is not clinging to the clamping and shifting roller 42, the supporting platform 46 can provide bottom support to reduce the metal strip from falling.

[0045] The end of the feeding rack 4 away from the detection seat 2 is rotatably connected to a swing arm 5, and the rotation axis of the swing arm 5 extends in the vertical direction. The rotation axis of the swing arm 5 is located between the end of the feeding rack 4 away from the detection seat 2 and the sliding seat 44. The swing arm 5 is in the shape of a bent rod. The end of the swing arm 5 away from the end of the feeding rack 4 bypasses the sliding seat 44 and extends between the fixed clamping roller 41 and the clamping roller 42. The end of the swing arm 5 away from the end of the feeding rack 4 is rotatably connected to a clamping wheel 51, and the rotation axis of the clamping wheel 51 extends in the vertical direction. The sliding seat 44 The side away from the clamping roller 42 abuts against the inner wall of the swing arm 5, and when the sliding seats 44 approach each other, the locking wheel 51 is located between the fixed clamping roller 41 and the clamping roller 42. When the sliding seats 44 move away from each other, the sliding seats 44 push the swing arm 5 to rotate outward, so that the locking wheel 51 moves away from the straight line space between the fixed clamping roller 41 and the clamping roller 42. A reset torsion spring 52 is provided at the connection between the swing arm 5 and the feeding rack 4. The reset torsion spring 52 is used to reset the locking wheel 51 to between the fixed clamping roller 41 and the clamping roller 42 when the sliding seats 44 move away from each other.

[0046] The positioning wheel 51 can position the metal strip between the fixed clamping roller 41 and the clamping roller 42, and try to avoid the situation that the metal strip between the fixed clamping roller 41 and the clamping roller 42 is in a straight line, and ensure that there is a metal strip with an extra length reserved between the fixed clamping roller 41 and the clamping roller 42, and at the same time reduce the situation that the metal strip between the fixed clamping roller 41 and the clamping roller 42 falls, thereby reducing the wear of the fixed clamping roller 41 and the clamping roller 42 on the metal strip. When the feeding frame 4 rotates, the sliding seats 44 move away from each other, pushing the swing arm 5 and the positioning wheel 51 to rotate outward, so that the metal strip can In order to be pulled out between the fixed clamping roller 41 and the clamping roller 42, the metal strip does not fall, and the wear of the metal strip is minimized. On the other hand, when the feeding rack 4 rotates but does not drive the sliding seats 44 away from each other, it is possible to pull the metal strip fed into the material. When the sliding seats 44 move away from each other, the swing arm 5 and the positioning wheel 51 are pushed to rotate outward, so that the metal strip with an extra length reserved can be moved in the direction away from the fixed clamping roller 41, thereby reducing the pulling and deformation of the metal strip, which affects the surface structure of the metal strip and the subsequent processing quality.

[0047] Reference Figure 1 and Figure 2, a connecting ring 47 is connected to the bottom of the feeding rack 4. The connecting ring 47 is slidably connected to the detection base 2. An annular sliding strip 471 is provided on the inner side wall of the connecting ring 47. The connecting ring 47 is slidably engaged with the detection base 2 through the annular sliding strip 471. A connecting inner ring 25 is slidably connected to the side wall of the detection base 2. Sliding rings are provided on both the top side and the bottom side of the connecting inner ring 25. The connecting inner ring 25 is in an embedded sliding fit with the detection base 2 through the sliding rings. The discharging clamp 23 is connected to the inner side wall of the connecting inner ring 25. The connecting inner ring 25 is in driving cooperation with the connecting ring 47. A first external gear ring 472 is connected to the outside of the connecting ring 47. A second external gear ring 251 is connected to the outside of the connecting inner ring 25. The specifications of the first external gear ring 472 and the second external gear ring 251 are the same. A rotating shaft 26 is rotatably connected to the side wall of the detection base 2. One end of the rotating shaft 26 is connected with a steering gear 261, and the other end is connected with an inner ring gear 262. The steering gear 261 is meshed with the first external gear ring 472. The specifications of the steering gear 261 and the inner ring gear 262 are the same. The inner ring gear 262 is meshed with the second external gear ring 251. The connecting ring 47 is in driving connection with the driving end of the steering driving member 22. The steering driving member 22 is installed on the side wall of the detection base 2. The driving end of the steering driving member 22 is connected with the rotating shaft 26.

[0048] When the feeding rack 4 and the feeding rotating cylinder 31 need to be steered, the steering driving member 22 is made to drive the rotating shaft 26 to rotate. The rotating shaft 26 drives the connecting ring 47 and the connecting inner ring 25 to rotate synchronously and at the same speed through the steering gear 261 and the inner ring gear 262 respectively, so that the feeding rotating cylinder 31 and the discharging roller 231 rotate simultaneously, enabling the metal strip between the feeding rotating cylinder 31 and the discharging roller 231 to rotate as a whole, reducing the situation where only a part of the metal strip between the feeding rotating cylinder 31 and the discharging roller 231 is twisted, reducing the recognition and scanning error, improving the processing quality, and at the same time reducing the situation where the metal strip is twisted and the structure is deformed.

[0049] A number of marking clamping members 27 are provided on the detection base 2. The number of the marking clamping members 27 is two and they are symmetrically arranged. An extension plate 28 is installed on the side wall of the detection base 2. The marking clamping members 27 are slidably connected to the extension plate 28. The marking clamping members 27 are located between the feeding rotating cylinder 31 and the scanning and recognition head 21. A transverse movement driving member 29 for driving the marking clamping members 27 to approach or move away from each other in the horizontal direction is provided on the extension plate 28. The transverse movement driving member 29 is a cylinder. The driving end of the transverse movement driving member 29 is connected with the marking clamping members 27.

[0050] Before the metal strip passes through the scanning and identifying head 21, it first passes between two marking clamping devices 27. The transverse driving member 29 drives the marking clamping devices 27 to approach each other horizontally, and tiny marking grooves are clamped out on the metal strip, so as to perform segmented marking on the metal strip according to the required unit length of processing. Every two marking grooves are one unit length. After the scanning and identifying head 21 identifies the marking grooves, it can be determined that it is a new unit length of the metal strip, which is convenient for identifying each unit length, improving the processing efficiency, and at the same time facilitating the determination of the pushing positions of the pushing plate 12 and the pressure-receiving rod 13 on the metal strip.

[0051] The implementation principle of the gold wire positioning device for gold jewelry processing in the embodiment of the present application is as follows: When it is necessary to scan and identify the raw material of the gold chain, the metal strip can be transported to the front of the scanning and identifying head 21 through the clamping and moving rollers 42, the fixed clamping rollers 41 and the feeding rotating cylinder 31 in sequence for identification and scanning. When the scanning and identifying head 21 determines that the preset small hole position of the metal strip is not facing the preset direction, it drives the connecting ring 47 and the inner connecting ring 25 to rotate, driving the feeding frame 4, the feeding rotating cylinder 31 and the discharging roller 231 to rotate simultaneously, so that the preset small hole position faces the scanning and identifying head 21, thereby accurately aligning the preset position, reducing errors and improving the processing quality. The clamping and moving rollers 42 and the positioning wheels 51 can reserve an extra length of the metal strip for the rotation of the feeding frame 4, reducing the situation of metal strip damage and indirectly improving the processing quality.

[0052] The above are all the preferred embodiments of the present application. This embodiment is only an explanation of the present application and does not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
