[0047] like Figure 3-19As shown, in one embodiment of the present invention, there is provided an automatic assembly system for automobile door panel buckles, comprising a frame 100, two material storage rails 200, two feeding mechanisms 300, an assembly mechanism 400 and a feeding mechanism 500. The frame 100 is provided with two fixture stations 101 for fixing the door panel, and the two material storage rails 200 are arranged in parallel on the frame 100, each material storage rail 200 corresponds to a fixture station 101, and the two material storage rails 200 correspond to buckle A and buckle B respectively. Each feeding mechanism 300 corresponds to a material storage rail 200, and the feeding mechanism 300 is used to convey the corresponding buckle into the material storage rail 200.

[0048] The assembly mechanism 400 includes a first driving member 401, a charging clip 402 and a clamping assembly 403. The first driving member 401 is arranged on the frame 100, and the first driving member 401 is a manipulator. The charging clip 402 and the clamping assembly 403 are both arranged on the first driving member 401. The charging clip 402 can be connected to the discharge end of one of the storage rails 200. The clamping assembly 403 can clamp the buckle A or the buckle B in the charging clip 402. The first driving member 401 is used to drive the charging clip 402 and the clamping assembly 403 to move. The feeding mechanism 500 is used to transport the buckle in one of the storage rails 200 to the charging clip 402, and the charging clip 402 can be loaded with the buckle A and the buckle B.

[0049] The clamping assembly 403 includes two clamps 4031 and a second driving member 4032. The clamps 4031 have a first end and a second end opposite to each other. A first groove 4033, a second groove 4034 and a third groove 4035 are provided on the side wall of the clamp 4031 facing the other clamp 4031. The first groove 4033, the second groove 4034 and the third groove 4035 are connected in sequence. The depth of the first groove 4033 is greater than the depth of the second groove 4034. The third groove 4035 runs through the end surface of the first end. The depth of the third groove 4035 gradually becomes shallower in the direction away from the second groove 4034. The second driving member 4032 is respectively connected to the second ends of the two clamps 4031. The second driving member 4032 is used to drive the two clamps 4031 to move closer to or away from each other.

[0050] To facilitate the description of the working principle of the assembly system, the two storage rails 200 are respectively referred to as storage rails 200a and storage rails 200b, and the two feeding mechanisms 300 are respectively referred to as feeding mechanisms 300a and feeding mechanisms 300b. The storage rail 200a is applicable to buckle A, and the storage rail 200a corresponds to the feeding mechanism 300a. The storage rail 200b is applicable to buckle B, and the storage rail 200b corresponds to the feeding mechanism 300b.

[0051] When the assembly system is working, the feeding mechanism 300a will convey the buckle A to the storage track 200a, and the feeding mechanism 300b will convey the buckle B to the storage track 200b, and the first driving member 401 will drive the charging clip 402 to align with one of the storage tracks 200 to load the buckle A and / or the buckle B. For example, when it is necessary to load the buckle A, the first driving member 401 drives the charging clip 402 to align and connect with the discharge end of the storage track 200a. Then, the feeding mechanism 500 can convey the buckle A in the storage track 200a to the charging clip 402. Subsequently, under the drive of the first driving member 401, the clamping assembly 403 can assemble the buckle A and the buckle B in the charging clip 402 on the door panel, thereby realizing the automatic assembly of the two buckles.

[0052] When the second driving member 4032 drives the two clamps 4031 to clamp the buckle A in the charging clip 402, the space formed by the two first grooves 4033 can accommodate the waterproof ring on the buckle A, thereby preventing the waterproof ring from being damaged due to clamping. The structural design of the third groove 4035 can be close to the root of the buckle A column, so that the buckle A can be clamped. Under the drive of the first driving member 401, the buckle A can finally be assembled on the door panel, thereby realizing the automatic assembly of the buckle A.

[0053] When the second driving member 4032 drives the two clamps 4031 to clamp the buckle B in the loading clip 402, the structural design of the third groove 4035 can be close to the root of the buckle B column, so that the buckle B can be clamped. With the cooperation of the robot, the buckle B can finally be assembled on the door panel, thereby realizing the automatic assembly of the buckle B.

[0054] The embodiment discloses an automatic assembly system for automobile door panel buckles, which can realize the feeding operation of buckle A and buckle B by designing two material storage tracks 200 and two feeding mechanisms 300. The feeding mechanism 500 can transport the buckles in one of the material storage tracks 200 to the loading clip 402. Under the drive of the first driving member 401, the clamping assembly 403 can assemble the buckle A and buckle B in the loading clip 402 on the door panel, thereby realizing the automatic assembly of the two buckles.

[0055] At the same time, the structural design of the clamp 4031 enables the space formed by the two first grooves 4033 to accommodate the waterproof ring on the buckle A, thereby preventing the waterproof ring from being damaged due to clamping. The structures of the second groove 4034 and the third groove 4035 can cooperate with the roots of the buckle A and buckle B columns, so that the clamping assembly 403 can adapt to buckles of both buckle A and buckle B at the same time, without the need to replace the clamping tooling, thereby improving the scope of application and production efficiency.

[0056] The automobile door panel buckle automatic assembly system can realize the continuous feeding, loading and assembly of two buckles, has a wide range of applications, a high degree of automation, and is more efficient than a tool that can only assemble one buckle, thereby improving production efficiency. At the same time, it also reduces the labor intensity and assembly errors caused by manual assembly.

[0057] In one embodiment, the groove wall of the first groove 4033 is an arc surface, the groove walls of the second groove 4034 and the third groove 4035 are both conical surfaces, the axis of the first groove 4033 is parallel to the length direction of the chuck 4031, the axes of the first groove 4033, the second groove 4034 and the third groove 4035 coincide with each other, and the groove depth of the second groove 4034 gradually deepens in the direction away from the first groove 4033.

[0058] The structural design of the first groove 4033, the second groove 4034 and the third groove 4035 needs to adapt to the column of the buckle A (for the convenience of description, it will be referred to as column A below), the column of the buckle B (for the convenience of description, it will be referred to as column B below) and the waterproof ring at the same time. Since the depth of the second groove 4034 gradually deepens in the direction away from the first groove 4033, the connection between the groove wall of the second groove 4034 and the groove wall of the third groove 4035 can effectively avoid the protrusion of column A and the protrusion of column B, thereby making the two clamps 4031 more stable when clamping the buckle A or the buckle B.

[0059] In one embodiment, the clamp 4031 is provided with a fourth groove 4036, the fourth groove 4036 is connected with the third groove 4035 and passes through the end surface of the first end, the groove wall of the fourth groove 4036 is a conical surface, the fourth groove 4036 coincides with the axis of the third groove 4035, and the groove depth of the fourth groove 4036 gradually becomes shallower in the direction away from the third groove 4035. When the two clamps 4031 clamp the buckle A or the buckle B, the connection between the fourth groove 4036 and the end surface of the first end will be pressed against the root of the column A or the column B, so that the clamping effect of the clamping assembly 403 can be further improved, and the buckle A or the buckle B can be clamped more stably.

[0060] In one embodiment, there is a gap 4037 between the two clamps 4031, and the connection between the first groove 4033 and the second groove 4034, the connection between the second groove 4034 and the third groove 4035, and the connection between the third groove 4035 and the fourth groove 4036 are arc transitions. The root of the column A and the root of the column B have different sizes. Therefore, the design of the gap 4037 between the two clamps 4031 ensures that the clamps 4031 are in effective contact with the root of the column A or the column B when clamping different buckles, thereby improving the clamping effect and avoiding the possibility of the buckle shaking when clamping.

[0061] In one embodiment, the two ends of the storage track 200 are respectively provided with a first feed port and a first discharge port, and the feeding mechanism 500 includes a base 501, two first push arms 502, a third driving member 503 and two clutch mechanisms. The base 501 is arranged on the frame 100, each first push arm 502 corresponds to a storage track 200, and the first push arm 502 is slidably matched on the base 501 along a direction parallel to the length direction of the storage track 200. The third driving member 503 is arranged between the two storage tracks 200, and the third driving member 503 can drive one of the first push arms 502 to extend into the corresponding first feed port, and push the buckle in the storage track 200 out of the first discharge port. Each clutch mechanism corresponds to the third driving member 503 and a first push arm 502, and the clutch mechanism is used to connect or disconnect the third driving member 503 and the first push arm 502.

[0062] For ease of description, the two push arms are referred to as the first push arm 502a and the first push arm 502b, and the two clutch mechanisms are referred to as the clutch mechanism a and the clutch mechanism b. The storage track 200a, the first push arm 502a and the clutch mechanism a correspond to each other, and the storage track 200b, the first push arm 502b and the clutch mechanism b correspond to each other.

[0063] When the loading clip 402 needs to be loaded with buckle A, the first driving member 401 drives the loading clip 402 to align and connect with the discharge end of the storage track 200a. Then, the clutch mechanism a connects the third driving member 503 with the first push arm 502a, and the clutch mechanism b disconnects the first driving member 401 from the first push arm 502b. In this way, the third driving member 503 can drive the first push arm 502a to push the buckle A in the storage track 200a into the loading clip 402 through the clutch mechanism a. After the first driving member 401 drives the first push arm 502a to reset, according to actual conditions, the clutch mechanism a can be realized to disconnect the third driving member 503 from the first push arm 502a, and the clutch mechanism b can be realized to connect the third driving member 503 from the first push arm 502b, thereby realizing the loading of buckle B.

[0064] At the same time, by designing a third driving member 503 and two clutch mechanisms, the clutch mechanism can realize the connection or disconnection between the third driving member 503 and the corresponding first push arm 502, so that when only one third driving member 503 is designed, the feeding operation of the buckles in the two storage rails 200 can be realized respectively, which simplifies the structure and improves the degree of automation.

[0065] In one embodiment, the clutch mechanism includes a first connection block 504, a second connection block 505, an insert block 506 and a lifting assembly. The first connection block 504 is connected to the third driving member 503, and the third driving member 503 is provided with a connecting arm, and the connecting arm is connected to two first connection blocks 504. The second connection block 505 is provided on the first push arm 502, and the horizontal height of the bottom surface of the second connection block 505 is higher than the horizontal height of the top surface of the first connection block 504, and the second connection block 505 is provided with a plug hole 5051. The plug block 506 is vertically slidably fitted on the first connection block 504, and the plug hole 5051 can be inserted into the plug hole 5051.

[0066] The lifting assembly is used to drive the plug block 506 to rise and insert into the plug hole 5051, and prevent the plug block 506 from exiting the plug hole 5051, or to allow the plug block 506 to descend and exit the plug hole 5051. The lifting assembly includes a limit block 507 and a fourth driving member 508. The limit block 507 is vertically lifted and matched on the base 501. The length direction of the limit block 507 is parallel to the length direction of the storage track 200. The limit block 507 is arranged below the plug block 506 and can lift the plug block 506. The plug block 506 can move against the top surface of the limit block 507. The fourth driving member 508 is arranged on the base 501, and the fourth driving member 508 is used to drive the limit block 507 to perform lifting actions.

[0067] When the buckle A in the material storage track 200a needs to be pushed into the loading clip 402, the first connection block 504a needs to be connected to the second connection block 505a. Therefore, the fourth driving member 508a will lift the limit block 507a, and the limit block 507a will push the insertion block 506a to move upward, so that the insertion block 506a can be inserted into the insertion hole 5051a, thereby achieving the connection between the first connection block 504a and the second connection block 505a.

[0068] At this time, the insert block 506b is not inserted into the insertion hole 5051b, and the first connection block 504b and the second connection block 505b are disconnected. Therefore, when the connecting arm drives the first connection block 504a and the first connection block 504b to move, it will only drive the second connection block 505a and the first push arm 502a synchronously, and will not drive the second connection block 505b and the first push arm 502b.

[0069] Next, the third driving member 503 drives the connecting arm to move, and the connecting arm will synchronously drive the first connecting block 504a, the second connecting block 505a and the first pushing arm 502a to move synchronously, so that the first pushing arm 502a can push the buckle A in the storage track 200a into the loading clip 402. Since the limit block 507a always abuts against the bottom of the plug block 506a, the plug block 506a will always slide against the top surface of the limit block 507a, so the plug block 506a will not be separated from the insertion hole 5051a, so that the stability of the connection between the first connecting block 504a, the second connecting block 505a and the first pushing arm 502a is guaranteed.

[0070] After the connecting arm, the first connecting block 504a, the first connecting block 504b, the second connecting block 505a and the first pushing arm 502a are reset, the second driving member 4032a will drive the limit block 507a to descend, and the plug block 506a will also descend along with the limit block 507a until the plug block 506a is completely separated from the insertion hole 5051a, thus achieving the disconnection between the first connecting block 504a and the second connecting block 505a. Finally, the feeding mechanism 300a will transport the buckle A into the storage track 200a, waiting for the next feeding.

[0071] In one embodiment, two first guide rods 509 are provided on the bottom surface of the first connection block 504, and a first stopper is provided at the bottom of the first guide rod 509. Two ears are provided on both sides of the plug block 506, and each ear is slidably fitted on the corresponding first guide rod 509 and abuts the first stopper. Each first guide rod 509 is sleeved with a first elastic member 510, and the two ends of the first elastic member 510 respectively abut the bottom surface of the first connection block 504 and the bottom surface of the ear. This structural design ensures the stability of the connection between the plug block 506 and the first connection block 504, and when the stopper 507 lifts the plug block 506 to rise and insert it into the socket 5051, the ear will further compress the elastic member. After the stopper 507 is lowered, the plug block 506 can not only be lowered under its own gravity, but also driven by the elastic member, thereby ensuring that the plug block 506 can smoothly exit the socket 5051.

[0072] In one embodiment, the clutch mechanism also includes a mounting bracket 511 connecting arm; 512, an electromagnet 513 and a magnetic attraction member 514, the mounting bracket 511 connecting arm; 512 is arranged on the base 501, the electromagnet 513 is arranged on the mounting bracket 511 connecting arm; 512, the magnetic attraction member 514 is arranged on the second connecting block 505, and the electromagnet 513 can be magnetically attracted to the magnetic attraction member 514.

[0073] When the first push arm 502 is at the initial position, the electromagnet 513 is energized and magnetically attracted to the magnetic attraction member 514 , thereby ensuring that the second connecting block 505 and the first push arm 502 do not move, so that the insertion block 506 can be aligned with the insertion hole 5051 .

[0074] When the push arm a is about to move, the electromagnet 513a is powered off, and the electromagnet 513a will no longer magnetically attract the magnetic element 514a. In this way, the third driving element 503 can drive the connecting arm, the first connecting block 504a, the first connecting block 504b, the second connecting block 505a and the first push arm 502a to move.

[0075] In one embodiment, the assembly mechanism 400 further includes a support frame 404, a material blocking assembly 405, an assembly drive assembly 406, a material pushing assembly 407, and a yielding drive assembly 408. The support frame 404 is disposed on the first drive member 401, the loading clip 402 is disposed on the support frame 404, a loading trough is disposed in the loading clip 402, a second feeding port is disposed at one end of the loading trough, and two clamps 4031 are disposed above the loading trough and close to the second feeding port.

[0076] The material blocking component 405 is used to block or open the second feed port, the assembly drive component 406 is used to drive the second drive member 4032 to perform a lifting action on the support frame 404, the pushing component 407 is used to push the buckle in the loading trough to move toward the second feed port, and the yielding drive component 408 is used to drive the loading clip 402 to yield to avoid the lifting action of the two chucks 4031.

[0077] The yield driving assembly 408 includes a base plate 4081, a first sliding unit 4082 and a fifth driving member 4083. The base plate 4081 is slidably fitted on the support frame 404 through the first sliding unit 4082. The loading clip 402, the material blocking assembly 405 and the material pushing assembly 407 are all arranged on the base plate 4081. The sliding direction of the base plate 4081 is parallel to the length direction of the loading trough.

[0078] The material blocking assembly 405 includes a sixth driving member 4051 and a first stopper 4052. The sixth driving member 4051 is installed on the bottom plate 4081. The sixth driving member 4051 drives the first stopper 4052 to open or block the second feed port. The assembly driving assembly 406 includes a seventh driving member 4061 and a second sliding unit 4062. The second driving member 4032 is installed on the support frame 404 through the second sliding unit 4062. The seventh driving member 4061 is used to drive the second driving member to move on the second sliding unit 4062.

[0079] The push assembly 407 includes a third sliding unit 4071, an eighth driving member 4072 and a second push arm 4073. The second push arm 4073 is installed on the bottom plate 4081 through the third sliding unit 4071. The eighth driving member 4072 is used for the second push arm 4073 to move on the third sliding unit 4071. The second push arm 4073 can extend into the loading chute and push the buckle in the loading chute toward the second feeding port for the clamp assembly to clamp.

[0080] After the clamping component 403 clamps the buckle near the second feed port, the sixth driving member 4051 drives the first stop block 4052 to open the second feed port, and then the fifth driving member 4083 drives the base plate 4081 to move away from the first stop block 4052 relative to the support frame 404. At this time, the loading clip 402, the blocking component 405 and the pushing component 407 will all move with the base plate 4081, and the assembly drive component 406 is installed on the support frame 404, so the assembly drive component 406 and the clamping component 403 will not move.

[0081] In this way, when the charging clip 402 and the bottom plate 4081 move, the clamp 4031 can be avoided, and the buckle clamped by the clamping assembly 403 will also slide out from the second feed port of the charging trough. Then the sixth driving member 4051 drives the first block 4052 to block the second feed port, and the seventh driving member 4061 drives the second driving member 4032 and the two clamps 4031 to continue to descend, and the first driving member 401 can drive the clamping assembly 403 to slide the clamped buckle into the slot on the door panel, and the second driving member 4032 drives the two clamps 4031 to open, so that the buckle can be released, thereby realizing the assembly of the buckle. After the clamping assembly 403 rises and resets, the fifth driving member 4083 will drive the bottom plate 4081, the charging clip 402, etc. to reset again, waiting for the next assembly.

[0082] In one embodiment, the feeding mechanism 300 includes a vibration plate 301, a feeding track 302, a linear vibrator, a transposition block 303, a ninth driving member 304, and a tenth driving member 305. The feeding track 302 is parallel to the storage track 200 and is arranged in a staggered manner. The feeding track 302 has a second discharge port. The feeding track 302 is installed on the linear vibrator. After the vibration plate 301 is started, the buckle in the vibration plate 301 will continuously move upward through the spiral track of the vibration plate 301 and finally transport the buckle to the feeding track 302. Under the action of the linear vibrator, the buckle in the feeding track 302 will continuously move toward the second discharge port.

[0083] The transposition block 303 is provided with a receiving groove that can accommodate a buckle. When the receiving groove is aligned with the second discharge port, the buckle closest to the second discharge port in the feed track 302 enters the receiving groove under the action of the linear vibrator, and then the third driving member 503 drives the transposition block 303 to move, and finally aligns the receiving groove with the first feed port. In this process, the transposition block 303 blocks the second discharge port, and even under the action of the linear vibrator, the buckle closest to the second discharge port in the feed track 302 can only rest on the transposition block 303 and cannot continue to move.

[0084] After the receiving groove is aligned with the second feeding port, the tenth driving member 305 drives the first pushing arm 502 to push the buckle in the receiving groove into the storage track 200. Then, the fourth driving member 508 drives the first pushing arm 502 to reset so that it avoids the transposition block 303, so that the ninth driving member 304 can drive the transposition block 303 to move, so that the receiving groove is aligned with the second feeding port. In this way, under the action of the linear vibrator, the buckle in the feeding track 302 will move to the receiving groove again, waiting for the next transposition.

[0085] In this embodiment, the second driving member 4032, the third driving member 503, the fourth driving member 508, the fifth driving member 4083, the sixth driving member 4051, the ninth driving member 304 and the tenth driving member 305 are all cylinders, and the seventh driving member 4061 and the eighth driving member 4072 are motors and gear rack structures. Some structures in the feeding mechanism 300 and the assembly mechanism 400 are prior art and are not described in detail in this embodiment. The feeding mechanism 500 also includes a second stopper for blocking or opening the storage track 200, and the second stopper is prior art and is not described in detail in this embodiment.
