Description

Technical Field

[0001] The utility model relates to the technical field of jewelry spring buckle processing equipment, in particular to a jewelry spring buckle automatic assembly machine. Background Art

[0002] In today's society, jewelry has become an indispensable part of human life. Most non-elastic chain jewelry, such as necklaces, bracelets, waist chains, decorative belts, etc., are equipped with various types of connecting buckles at both ends for easy use. Among them, spring buckles are the most common and stable connecting buckles. They control the opening and closing of spring buckles through the cooperation of paddles and springs. The opening and closing action is passive, and external force is required to move the paddles to compress the springs. The closing is driven by the active rebound of the springs. Therefore, once the jewelry is connected and the spring buckle is locked, the connection part is not easy to slip off.

[0003] The existing spring buckle mainly consists of three parts, namely, the buckle body, the spring and the pick; the buckle body is a hollow tube, the buckle body is an arc shape with one side open, and the outer wall of the buckle body is provided with a slot-shaped through hole connected to the inside of the buckle body. In the process of assembling these three parts, the spring needs to be installed inside the buckle body first, and then the pick is installed inside the buckle body through the slot-shaped through hole, one end of which abuts against the spring, and the other end abuts against the end of the buckle body. Under normal conditions, the pick is subjected to the elastic force of the spring, and the pick abuts against the buckle body to complete the closed state. Traditionally, the assembly of the spring buckle is completed by workers manually, or after the spring is installed to the buckle body by equipment, the subsequent installation of the pick needs to be completed manually, but in the process of assembly, it needs to be completed manually, this assembly method is inefficient and has high labor costs; moreover, some spring buckles are relatively small, which makes it difficult to assemble them. During the assembly process, it is easy to cause low assembly precision and reduce product yield. Utility Model Content

[0054] In the present invention, in order to meet the continuous feeding of the button body 91, the button body translation mechanism 13 also includes a button body material dividing plate 134 installed on the button body translation pushing seat 1321, and the button body material dividing plate 134 is arranged on the outside of the button body downward movement guide rail assembly 12; the button body material dividing plate 134 is protruded outwardly on one side of the button body downward movement guide rail assembly 12 with a button body material dividing upper limit protrusion 1341 and a button body material dividing lower limit protrusion 1342, and the button body material dividing upper limit protrusion 1341 and the button body The lower limit protrusions 1342 for material distribution are all arranged along the X direction; along the vertical direction, there is a distance between the upper limit protrusion 1341 for buckle body material distribution and the lower limit protrusion 1342 for buckle body material distribution, the upper limit protrusion 1341 for buckle body material distribution is correspondingly arranged above the buckle body push notch 1323 and close to the buckle body downward guide rail assembly 12, and the lower limit protrusion 1342 for buckle body material distribution is arranged along the X direction on the outside of the upper limit protrusion 1341 for buckle body material distribution and close to the buckle body translation push plate 1322.

[0055] In the process of the buckle body 91 falling along the buckle body downward guide rail 121, it is first blocked by the buckle body material separation upper limit protrusion 1341, and then the buckle body material separation plate 134 moves along the X direction with the buckle body translation push seat 1321 to the side close to the assembly turntable 6. In the process of movement, the buckle body material separation upper limit protrusion 1341 gradually separates from the buckle body 91, and the buckle body 91 gradually falls and contacts the buckle body material separation lower limit protrusion 1342. Therefore, the buckle body 91 is blocked by the buckle body material separation lower limit protrusion 1342 at this time. Block; when the buckle body dividing plate 134 moves in the opposite direction with the buckle body translation push seat 1321, the buckle body 91 gradually separates from the buckle body dividing lower limit protrusion 1342, and then freely falls on the buckle body loading carrier 1312. During this process, the buckle body dividing upper limit protrusion 1341 continues to block the subsequent buckle body 91 falling thereon to prevent it from falling together, thereby realizing that each buckle body 91 is placed separately on each assembly station 611 of the assembly turntable 6, and continuous loading is realized.

[0056] It should be noted that the buckle body downward positioning piece 122 is arranged close to the buckle body material distribution upper limit positioning protrusion 1341; in the process that the buckle body 91 falls behind the buckle body material distribution upper limit positioning protrusion 1341 and gradually separates from it, the buckle body 91 is affected by the movement of the buckle body material distribution upper limit positioning protrusion 1341, and rotates around the axis of the buckle body downward guide rail 121. When its opening moves to the buckle body downward positioning piece 122, under the action of its own gravity, the opening of the buckle body 91 contacts the buckle body downward positioning piece 122. The buckle body downward positioning piece 122 restricts the rotation of the buckle body 91 and at the same time limits the opening direction of the buckle body 91, thereby setting the opening of the buckle body 91 to a uniform direction.

The good product detection action member 44 is provided with an arc-shaped toggle groove 441 matched with the paddle 92; the good product detection sensor 46 is matched with the good product detection action member 44. In a normal state, the good product detection action member 44 abuts against the good product detection sensor 46.

[0081] The spring buckle feeding device 5 includes a spring buckle feeding cylinder 51 arranged vertically, and a good product feeding pipe 52 and a defective product feeding pipe 53 arranged vertically from top to bottom are installed on the driving end of the spring buckle feeding cylinder 51; or, a defective product feeding pipe 53 and a good product feeding pipe 52 arranged vertically from top to bottom are installed on the driving end of the spring buckle feeding cylinder 51. The spring buckle feeding cylinder 51 is controlled by the good product detection sensor 46.

[0082] The assembly turntable 6 includes a turntable body 61 and a station opening and closing mechanism 62; the turntable body 61 is rotatably arranged, and at least four assembly stations 611 are arranged equidistantly along its circumference on the turntable body 61, and the assembly stations 611 are used to fix or release the buckle body 91; the station opening and closing mechanism 62 is driven and connected to the external power device 8, and the station opening and closing mechanism 62 is used to control one of the assembly stations 611 to open and receive the buckle body 91, and simultaneously control another assembly station 611 to open and release the buckle body 91.

[0083] The following is a brief description of its working principle based on the above structural description:

[0084] First is the loading process of the button body 91: the button bodies 91 that are sequentially arranged and moved out of the button body vibration plate 11 slide freely downward along the button body downward guide rail 121, and in the process of falling, the button body dividing plate 134 divides the button bodies 91, and a button body 91 after dividing slides freely onto the button body loading carrier plate 1312; the button body translation push seat 1321 pushes the button body translation push plate 1322 to move along the X direction, and the button body translation push plate 1322 pushes the button body 91 to move to the side close to the assembly turntable 6, so that it is pushed to an assembly station 611 of the assembly turntable 6, completing the loading process of the button body 91.

[0085] The buckle body 91 pushed onto the assembly station 611 is driven by the turntable body 61 to move the buckle body 91 toward the spring feeding device 2 to perform the spring assembly process, specifically as follows: the spring moved out of the spring vibration disk 21 enters the spring through-hole 2221 through the spring receiving through-hole 2211 after being divided by the spring dividing mechanism 26; the spring reversing member 222 drives the spring to reverse, so that the end of the spring faces the side close to the assembly turntable 6. At this time, the spring through-hole 2221 is aligned with the spring pushing member 231, and the spring pushing member 231 passes through the spring pushing through-hole 2212, and pushes the spring located in the spring through-hole 2221 to the side close to the assembly turntable 6, and pushes it through the grooved through-hole on the buckle body 91 until it is pushed to the inside of the buckle body 91, thereby completing the spring feeding action on the buckle body 91.

[0086] After the buckle body 91 is assembled with the spring, the buckle body 91 is driven by the turntable body 61 to move together with the spring to the shifting piece blanking and feeding device 3 to perform the shifting fork assembly process, which is specifically as follows:

[0087] When the paddle 92 is formed, the paddle material strip 7 is clamped to the material strip channel 32211, and enters the punching mounting seat 3221 through the material strip channel 32211. The punch transmission assembly 341 drives the punch 3223 to move upward, and the punch 3223 cooperates with the punching and forming block 3222 to punch the paddle material strip 7 to form the paddle 92. Then the punch 3223 continues to move upward, driving the paddle 92 to move up to the paddle pushing groove 32222, waiting to be pushed out.

[0088] When the paddle 92 moves out, the paddle push rod transmission assembly 342 drives the paddle push rod 3231 to slide back and forth along the Y direction. When the paddle push rod 3231 moves toward the side close to the punch 3223, the paddle push rod 3231 pushes the paddle 92 to move it out. When the paddle push rod 3231 moves away from the punch 3223, a space is left for the paddle forming hole 32221, so that the punch 3223 can continue to drive the next paddle 92 to move up into the paddle pushing groove 32222.

[0089] When the paddle 92 is loaded, the driving end of the cylinder 3325 drives the clamping claw push rod 3324 to move to the side close to the paddle blanking mechanism 322, pushing the rear ends of the upper clamping claw 33231 and the lower clamping claw 33232, so that the front ends of the two are close to each other and cooperate with each other to clamp and fix the paddle 92; the clamping sleeve transmission assembly 351 drives the clamping sleeve 3322 to rotate around its own axis, thereby driving the clamping claw assembly 3323 and the clamped paddle 92 to rotate around the axis of the clamping sleeve 3322 The paddle 92 moves, driving the paddle 92 to move toward the side close to the assembly turntable 6. During the movement of the paddle 92, the assembly station 611 also drives the buckle body 91 to rotate together, and the buckle body 91 and the paddle 92 approach each other until the paddle 92 is inserted into the buckle body 91. During this process, the paddle 92 abuts against the inside of the buckle body 91, and the two legs of the paddle 92 are squeezed and extended to both sides along the inner wall of the buckle body 91, so that one of the legs abuts against the spring, and the other leg extends out of the opening of the buckle body 91 and abuts against the buckle body 91.

[0090] Afterwards, the dial wheel 3326 moves to the side close to the paddle punching mechanism 322, and the dial wheel 3326 drives the front ends of the upper clamping jaw 33231 and the lower clamping jaw 33232 to move away from each other, completing the opening action and releasing the paddle 92. Then, the clamping sleeve transmission assembly 351 drives the clamping sleeve 3322 to rotate in the opposite direction, driving the clamping jaw assembly 3323 to move to the side away from the assembly turntable 6 until it returns to the avoidance groove 32212, thereby clamping and fixing the next paddle 92.

[0091] After the buckle body 91 on the assembly station 611 is assembled with the paddle 92, a spring buckle is formed. A spring buckle that can be opened or closed normally by compressing the spring is defined as a good product; on the contrary, a spring buckle that cannot be opened or closed normally is a defective product. The spring buckle on the assembly station 611 continues to move toward the good product detection device 4. During the movement, the paddle 92 extending out of the buckle body 91 abuts against the arc-shaped paddle groove 441, and the good product detection action piece 44 pushes the paddle 92 to compress the spring. At the same time, the good product detection action piece 44 is separated from the good product detection sensor 46; after the spring buckle continues to be driven, the paddle 92, under the elastic action of the spring, pushes the good product detection action piece 44 to move in the opposite direction and abut against the good product detection sensor 46. At this time, the current spring buckle is defined as a good product. If the spring buckle continues to be driven, and the paddle 92 is not affected by the elastic action of the spring, or the elastic action of the spring does not push the good product detection action piece 44 to move in the opposite direction and abut against the good product detection sensor 46 through the paddle 92, the good product detection action piece 44 will move in the opposite direction and will remain in a separated state with the good product detection sensor 46. At this time, the spring buckle feeding cylinder 51 moves up or down, driving the defective product feeding pipe 53 to correspond to the assembly station 611, and the station opening and closing mechanism 62 controls the assembly station 611 to open and then release the buckle body 91 to enter the defective product feeding pipe 53. Otherwise, it controls the assembly station 611 to open and then release the buckle body 91 to enter the good product feeding pipe 52 for feeding.

[0092] When the good product detection action piece 44 and the good product detection sensor 46 are in a separated state, the defective product reset piece 43 is driven by the good product detection action piece 44 to move in the opposite direction close to the dial wheel 3326, and the clamping sleeve 3322 drives the dial wheel 3326 to move toward the side close to the assembly turntable 6. At this time, the defective product reset piece 43 is toggled by the dial wheel 3326, so that the good product detection action piece 44 rotates toward the side close to the dial wheel 3326 until it abuts against the good product detection sensor 46; when the good product detection action piece 44 and the good product detection sensor 46 are in an abutting state, since the defective product reset piece 43 is driven by the good product detection action piece 44 to follow the dial wheel 3326, there is a gap between the defective product reset piece 43 and the dial wheel 3326, and the dial wheel 3326 cannot toggle the defective product reset piece 43, and there is no need to drive the good product detection action piece 44 to rotate.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
